The Neurobiology of Parkinsons Disease Essay - 1531 Words

The Neurobiology of Parkinsons Disease In neuroscience it is assumed that the central nervous system governs and defines all aspects of behavior (Grobstein, 1998). Therefore, the brain, the hub of the central nervous system, is responsible for integrating all sensory and motor patterning. To understand the mechanisms of neurobiology it is often useful to observe the nervous system at the level of the neuron. Integration and communication between neurons is facilitated by neurotransmitters, chemicals which act as intermediaries at the synaptic gap (Delcomyn, 1998). Many behavioral disorders have a neurochemical basis, oftentimes associated with abnormal neurotransmitter activity. These abnormalities are thought to stem from†¦show more content†¦The National Parkinsons Foundation estimates that each PD patient pays $2500 a year on medicines alone. When accounting for Social Security and nursing home payments, Parkinsons Disease costs over $5.6 billion annually to the nation (PD Web, 1998). Despite the high occurren ce of Parkinsons, it is still not always recognized as a significant medical problem. The symptoms are often ignored in the elderly because they are thought to be part of the natural process of aging (PD Web, 1998). Symptoms include tremors in hands, arms, legs, jaw, and face; slowness of movement, or bradykinesia, and difficulties in balance and coordination. As the chronic disease progresses, PD patients may have difficulty with simple tasks, such as walking and talking (PD Web, 1998). Much of the oversight of PD in medical research, and of other neurodegnerative diseases associated with elderly populations, like Alzheimers, could be a reflection of a dismissive attitude towards the aging process in the medical community and American culture. The primary symptoms of Parkinsons Disease stem from the deterioration of the part of the brain that controls motor functioning (NHGRI, 1998). This region is the substantia nigra which is found deep within the brain stem and contains neuronomelanin, pigment cells, which synapse to cells of the striatum. The striatum is responsible for balance, control of movements, andShow MoreRelatedA Red Shifted Variant Of Channelrhodopsin Allows Deep Transcranial Optogenetic Excitation770 Words   |  4 Pageswill assist in providing background information regarding transcranial options for the use of chronic studies.

Another chemical commonly used is ethanol in the aseptic technique and this too was varied in the amount of time the seeds were soaked before being placed in varying times and concentrations of the sodium hypochlorite. Ultimately, in order to use the barley seeds we need have a sterilization technique that can eliminate majority of fungal contamination while not harming the germination of the chosen seeds. I propose an experimental idea to eliminate fungal contamination from barley seed germination. Materials and Methods Aseptic Technique The working area was sprayed down completely with 95% Ethanol before the seeds were used.The forceps used to transfer the seeds from liquid to media were sterilized using the ethanol. Seed Sterilization Procedure Using aseptic techniques 20 barley seeds obtained from the paper bag kept in the fridge were transferred into sterile distilled water and let to sit in a drawer for 20 hours overnight before being transferred to 100% bleach with a drop of dish liquid (Inatomi and Slaughter, 1971). We will write a custom essay sample on Using an Experimental Technique or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The seeds were soaked in the bleach for a total of 2 hours before being dipped in sterile distilled water and placed on Petri dishes with minimal media and placed in a growth chamber.The germination of the seeds was monitored for 7 days for any fungal contamination. Results After 3 days the seeds were germinating (13 out of 20) and there was no visible evidence of fungal growth. 5 Days: there were no contaminants. 7 Days: no contaminants. || 3 Days seed growth. No contaminants. |3 Days seed growth. No contaminants. | || 5 Days seed growth. No contaminants. |5 Days seed growth. No contaminants. | Discussion Fungal contaminations can be a problem when trying to germinate seeds and a successful experiment is needed to sterilize the barley seeds for further experimentation.I proposed a sterilization experiment for barley seeds and had success with 65% germination and 0% fungal growth. This sterilization technique could provide a good beginning point to begin other experimentation on germination success of barley seeds, without the hassle of fungal contamination to destroy possible results. The overnight soak in the water forced the fungal spores to begin germinating and thereby making it possible for the 2 hour bleach soak to become more effective in eliminating the fungus and other contaminants from the seed coat.The few seeds which did not germinate could have had too much bleach penetration and therefore killed these seeds, however the success was more beneficial than the failure, and so this novel sterilization technique was effective in its elimination of fungal contaminations while providing a good germination rate of the barley seeds.

Zigbee Essay Example

Zigbee Essay A typical IEEE 803. 15. 4-based, ZigBee-complaint device is shown in figure 1. [pic] Figure 1. Typical 802. 15. 4/ZigBee Device that has included antenna, RF data modem, applications processor, all necessary passive and 16MHz crystal about 15x40mm – Courtesy Freescale Semiconductor. The ZigBee Alliance released their specification to the public in June 2005, and since then the playing field has become much simpler for product designer who want to their sensor or control application. An open and growing industry group of more than 180 companies from product/system OEMs to application developers to semiconductor companies, the Alliance has worked hard to provide a technology that takes best advantages of the robust IEEE STD 802. 15. 4 short-range wireless protocol, adding flexible networking, strong security tools, well-defined application profiles, and a complete interoperability, compliance and certification program to ensure that end products designed for residential, commercial and industrial spaces work well and network information smoothly. Need of ZigBee: There are a multitude of standards that address mid to high data rates for voice, PC LANs, video, etc. However, up till now there hasn’t been a wireless network standard that meets the unique needs of sensors and control devices. Sensors and controls don’t need high bandwidth but they do need low latency and very low energy consumption for long battery lives and for large device arrays. There are a multitude of proprietary wireless systems manufactured today to solve a multitude of problems that also don’t require high data rates but do require low cost and very low current drain. We will write a custom essay sample on Zigbee specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on Zigbee specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on Zigbee specifically for you FOR ONLY $16.38 $13.9/page Hire Writer These proprietary systems were designed because there were no standards that met their requirements. These legacy systems are creating significant interoperability problems with each other and with newer technologies. The ZigBee Alliance is not pushing a technology; rather it is providing a standardized base set of solutions for sensor and control systems. The physical layer was designed to accommodate the need for a low cost yet allowing for high levels of integration. The use of direct sequence allows the analog circuitry to be very simple and very tolerant towards inexpensive implementations. The media access control (MAC) layer was designed to allow multiple topologies without complexity. The power management operation doesn’t require multiple modes of operation. The MAC allows a reduced functionality device (RFD) that needn’t have flash nor large amounts of ROM or RAM. The MAC was designed to handle large numbers of devices without requiring them to be â€Å"parked†. The network layer has been designed to allow the network to spatially grow without requiring high power transmitters. The network layer also can handle large amounts of nodes with relatively low latencies. Network Feature: While ZigBee supports a variety of network topologies, including star, mesh and cluster networks, mesh networking is a fundamental and differentiating attribute to ZigBee’s design. In fact, mesh network support is so integral to ZigBee’s value proposition that the name is based on the ZigBee Principle; the zigzag path of bees that serves to signal a new food source to other members of the colony. The bees’ survival depends on the continuous communication of information between every member of the colony. A mesh network is comprised of a network coordinator or master device and can connect up to 65,000 network nodes, serving as full-function devices (FFD) or reduced-function devices (RFD). A full-function device (FFD) carries full 802. 15. 4 functionality and all features specified by the standard. Its computing power makes it well suited for a network router function. A reduced-function device (RFD) is generally used at the network edge. All of these devices can be no more complicated than a transceiver, a simple 8-bit MCU and a pair of AAA batteries. Through a series of redundant pathways, a signal initiated from a sensor or node on the network seeks out the closest connection for routing data and allows for either a single hop to the master device or multiple hops to successfully conclude its data transmission. The continuous flow of communication exacted by a mesh network topology provides the reliability required for wireless-based connectivity of remote monitoring and sensing controls. By providing multiple pathways for data to travel, a mesh network eliminates the single point of failure scenario and affords a transparent recovery of a network node. Designed to be highly adaptive and scalable, the ZigBee specification allows a new device or network node to be added and adjusts to the addition through a simple request to the master device. Low power consumption, simply implemented. Users expect batteries to last many months to years! Consider that a typical single family house has about 6 smoke/CO detectors. If the batteries for each one only lasted six months, the homeowner would be replacing batteries every month! Bluetooth has many different modes and states depending upon your latency and power requirements such as sniff, park, hold, active, etc. ZigBee/IEEE 802. 15. 4 has active (transmit/receive) or sleep. Application software needs to focus on the application, not on which power mode is optimum for each aspect of operation. Even mains powered equipment needs to be conscious of energy. Consider a future home with 100 wireless control/sensor devices, ZigBee devices will be more ecological than its predecessors saving megawat ts at it full deployment. Low cost (device, installation, maintenance). Low cost to the users means low device cost, low installation cost and low maintenance. ZigBee devices allow batteries to last up to years using primary cells (low cost) without any chargers (low cost and easy installation). ZigBee’s simplicity allows for inherent configuration and redundancy of network devices provides low maintenance. High density of nodes per network. ZigBee’s use of the IEEE 802. 15. 4 PHY and MAC allows networks to handle any number of devices. This attribute is critical for massive sensor arrays and control networks. Simple protocol, global implementation. ZigBee’s protocol code stack is estimated to be about 1/4th of Bluetooth’s or 802. 11’s. Simplicity is essential to cost, interoperability, and maintenance. The IEEE 802. 15. 4 PHY adopted by ZigBee has been designed for the 868 MHz band in Europe, the 915 MHz band in N America, Australia, etc; and the 2. 4 GHz band is now recognized to be a global band accepted in almost all countries. ?

Application: ZigBee networks consist of multiple traffic types with their own unique characteristic, including periodic data, intermitted data and repetitive low latency data. The characteristics of each are as follows: * Periodic data- usually defined by the application such as a wireless sensor or meter. Data typically is handled using a beaconing system whereby the sensor wakes up at a set time and checks for the beacon, exchanges data and goes to sleep. * Intermitted data- either application or external stimulus defined such as a wireless light switch. Data can be handled in a beaconless system or disconnected operation, the device will only attach to the network when communication is required, saving significant energy. *Repetitive low communication data- uses time slot allocation such as a security system. These applications may use the guaranteed time slot (GTS) capability. GTS is a method of QoS that allows each device a specific duration of time as defined by the PAN coordinator in the Superframe to do whatever it requires without contention or latency. Market Opportunities: ZigBee is the only standards-based technology designed to address the unique needs of low-cost, low-power, wireless sensor networks for remote monitoring, home control, and building automation network applications. Within the residential control market, intelligent sensors will provide greater control of lighting, heating, cooling, watering, appliance-use and security systems from anywhere in the home. With greater automation of home control systems, homeowners can adjust their environment to run more efficiently, reducing utility costs. Homeowners will be able to buy off-the-shelf products and be assured that they’ll work together in their networked environment. Because ZigBee is well suited for applications that require low power, such as light switches and sensors, it can operate using standard off-the-shelf batteries for months, years or even decades. Homes equipped with ZigBee-based networks will make it easy for builders, contractors, and home-supply manufacturers to reconfigure heating, lighting, and security systems to accommodate additions and the remodeling of kitchens, bathrooms and other property-value–enhancing projects. Developers for building automation can take advantage of the ZigBee specification to build and deploy wireless monitoring networks that help to centralize the management of lighting, heating, cooling and security systems and provide the flexibility to reconfigure systems quickly and ost-effectively to adjust for individual or tenant changes within a building structure. While initially focused on the home automation and building automation market segments, ZigBee has the potential to be a key driver in enabling the broad-based deployment of wireless networks for a variety of market segments including industrial automation and controls, automatic meter reading, personal health-care–monitoring devices, PCs and peripherals, supply-chain and logistics management, and other future market segments. ? ZigBee v/s Bluetooth: Bluetooth seems best suited for: Synchronization of cell phone to PDA Hands-free audio PDA to printer @ While ZigBee is better suited for: †¢ Controls †¢ Sensors †¢ Lots of devices †¢ Low duty cycle †¢ Small data packets †¢ Long battery life is critical @ Air Interface comparison: ZigBee Bluetooth Peak Information Rate Peak Information Rate ~128 Kbit/second ~108-723 Kbit/second @ Power consideraion: ZigBee Bluetooth # 2+ years from ‘normal’ batterie# Power model as a mobile phone (Regular daily charging) Designed to optimize slave# Designed to maximize ad-hoc Power requirements functionality ? Conclusion: ZigBee devices can quickly attach, exchange information, detach, and then go to deep sleep to achieve a very long battery life. ZigBee devices have a real potential to solve the challenge of bringing simple, effective wireless connectivity to low-rate sensors and control devices at an effective cost. ?

Come to Pass

Come to Pass Come to Pass Come to Pass By Maeve Maddox A common English idiom is â€Å"come to pass†: to come to pass: to happen, take place in the course of events, come about, occur, be fulfilled. Here are some correct uses of the expression: all things, good and bad, come to pass. It shall come to pass. Don’t give up on your God-given dreams. it seems slow, do not despair, for these things will surely come to pass. Lately, I’ve noticed an odd distortion of this idiom into â€Å"goes to pass†: Love remember who comes 1st in your life, everything goes to pass, but Gods spirit will always surround usAmen! Most of the time, the first thought that comes is of that everything goes to pass, if everything goes to pass, we will eventually be merging with 3SA. I have done as much as I can to make sure people dont get evicted from our ceremony venue, and that everything goes to pass without riots. These examples come from forums, inspirational blogs, and blog commentscontexts in which nonstandard English is well-represented. However, I found an example of a similar distortion on a page that has the Quaker Oats logo at the top.

I'm sending you two articles could you please use them only, extract the info and write about Non Lipid Cardiovascular Risk Factors and Flow basis Markers - Essay Example While the classical view of IHD has been the accumulation of plasma lipids and other sedimentary substances (plaques) on arterial walls, diminishing the lumens by large percentages till serious impediment to blood flow occurs that lead to the pathological condition. There are also other factors that progressively weaken and rupture arterial walls and also seriously affect blood flow (Libby, 2006). The principal predictive potential to assess degrees of progression towards cardiovascular disease is assaying the levels of these risk factors in the blood. These factors are consequently called biomarkers and since they generally affect blood flow to the heart they are also called flow basis biomarkers. This paper is assessing the predictive values of some non-lipid biomarkers. Biomarkers capable of predicting cardiovascular risk are generally categorised into eight groups - 'inflammatory markers, markers for plaque erosion and thrombosis, lipid-associated markers, markers of endothelial dysfunction, myocardial injury or dysfunction markers, oxidative stress, metabolic markers and markers of neovascularisation' (Cooke, 2006). Common lipid biomarkers are low density lipoprotein (LDL) and high density lipoprotein (HDL) cholesterol including oxidised LDL cholesterol, small dense LDL cholesterol, lipoprotein and lipoprotein-associated phosphol

Online Assessment - Essay Example RESPONSE 1 Samba Bank uses two Cialdini weapons of influence (Polanski 1-6), which includes reciprocity and scarcity intentionally. Notably, reciprocity dictates that whenever we receive value, we get an impulse to give value back (Cialdini 3-8). Indeed, in some cases, we may even get inspired to give back more value than we received. Indeed, whenever we receive value free in the marketing, it is for impelling reciprocity. Hence, we have so many promotions, discounts, and gifts in the market to trigger us into buying more (Cialdini 3-8). In the case of Samba bank, this weapon applies where the bank hospitalizes customers with expensive kinds of coffee, dates, and chocolates, which get customers satisfaction. The reciprocity effect is that the bank will maintain its customers and encourage them to do more transactions. As branch manager, I also use this weapon mostly when dealing with a customer who is out of the country and his time deposit has matured. I seek to satisfy such custome rs when they call the bank for a renewal instead of following the formal paper work process of renewal. As such, I renew their accounts over the phone and wait for their signatures until they come. Hence, I satisfy their needs with an aim of maintaining them and gaining reciprocity when they return. Moreover, I unfreeze customers’ accounts while they are abroad if the cause to freeze was a simple issue like expiry of their ID. In this way, the customers will be able to use the account while travelling and update their ID when they return. This results to reciprocity as such customers invest in the bank for a long time. I also ensure that customers seeking business loans get the money within a short time with an aim of gaining reciprocity when their businesses grow. Scarcity is other weapon used in Samba bank to derive a perception that a financial product or service is limited or diminishing thus, creating more demand for the product (Cialdini 199-207). Indeed, the scarcity w eapon creates promotions, which seemingly end at a certain time but actually never ends. They only encourage more sales at the end of the promotion time (Cialdini 199-207). In Samba bank, there are random offers to attract more customers to the bank or increase the cash flow. Indeed, the bank offers a chance for customers to deposit smaller amounts than normal to upgrade their accounts. For example, the bank allows customers to upgrade from the Blue to Gold segment on depositing only $ 25000 instead of the normal $75000. This compels customers to deposit in their accounts with money from other banks thus increasing Samba’s cash flow. Moreover, the bank offers the customers a chance to enjoy free credit card life at no annual fee for a short period. This attracts new customers to the benefit of the bank. RESPONSE 2 Samba bank uses various marketing strategies that relate to the concepts/theories in Ariely’s Predictably Irrational book. Such concepts include the cost of zero cost concepts and the power of price concept. The concept of cost of zero cost implies that humans consider losses and profits before purchasing but when something is free, customers do not consider the losses (Ariely 50-56). Indeed, customers get the perception that the product on offer has more value than its face value. Indeed, people would wait for long to get a free thing (Ariely 49-54). As such, this concept is very powerful in triggering customer’

DBQ Reconstruction Essay Example for Free

DBQ Reconstruction Essay The union victory in the Civil War gave four million slaves their freedom, but reuniting the South with the North introduced a new set of significant challenges. The Congress Reconstruction were the efforts to establish and protect citizens rights of freedom. Democrats led to the failure of the Congress Reconstruction by forgiving those who participated in the Civil War who were still in favor of slavery and inequality. This act of Amnesty led to three major obstacles for reconstruction: the emergence of the Ku Kux Klan, the development of black codes, and the Compromise f 1877. The emergence of the Ku Kux Klan was one of the main contributors to the failure of the Congress Reconstruction, leaving open spots for other major events that brought completely down the reconstruction. On November 23, 1868, in Tennessee, General George Thomas explained that the purpose of the Ku Kux Klan was to allow the Southern people that participated in the Civil War to come in union with those who had abandoned the thought of inequality. This gave them the advantage to bring back inequality and kill black men. (Document 2). By forgiving these Southern people, illing freedmen became easy. These people that were being forgiven had the same mentality from before the war, which was involved with the approval of slavery and the inequality there should be because black men werent like white men. Kenneth Stampp, a history professor form the University of California at Berkeley, expressed himself in The Era of Reconstruction, 1865-1877 about how in May 1872, the Congress developed an Amnesty act to reestablish the right to vote for the majority of those Southerners that had been forgiven. (Document 3). Giving the right to vote to these eople, put the reconstruction in danger. The right of voting allowed Southerners to vote for someone that would still want slavery. Voting for someone with a mentality like that would Just allow slavery back, and thats why The Congress Reconstruction started to fail. Even though the black codes were created with the purpose of giving freedmen equal rights like white men, the codes werent followed correctly and black men were still being discriminated. The black codes were supposed to follow the 13, 14, and 15th amendment, but they werent quite followed the way it was supposed to. Both black and white men were given the same rights, but everything was separated between races, one was for black men and one for white men, showing discrimination. When the black codes were established, black men became freedmen, but even though these men could start living as freedmen, many decided to stay as slaves. In a compilation of these interviews published by Benjamin Botkin in 1945, John McCoy is quoted as saying, l works for Marse John he says one morningJohn, you can go the government say you is free l didnt know nothing what money was, nohow, but I knows Ill git plenty victuals to eat, so I stays (Document 7). The majority of slaves had been slaves through their entire life. These people didnt know how to live themselves. Black men were ignorants on how to live without being a slave, so many, just like McCoy, decided to stay where they were working so their owners would provide them an easier way of surviving even though they were still working as slaves. In 1935, an African-American historian, Dr. W. E. B. DuBois, published a book of the history of Reconstruction where he wrote, Negros who wanted to work must not dabble in politics. Negroes who wanted to increase their income must not agitate the Negro problem in order to earn living, the American Negro was compelled to give up his political power (Document 6). This excerpt of the book shows how black men where not only being discriminated, but being left out politically too. If black men wanted work being freedmen, then they would have to stay out of the political power. White men were powerful and this is why giving up political power wasnt an option, but a forceful act from the white. Black codes were not being followed, white men always managed to find a way to obtain what they wanted. The reconstruction was failing because nobody was respecting laws anymore, and black men couldnt do anything about it besides remaining quiet and following white mens instructions, which became their only real guarantee of surviving. The Compromise of 1877 was created to decide which candidate should be taken as a winner, either Hayes or Tilden, leading towards a decision that helped the Congress Reconstruction fail. As can be seen in the electoral distribution map from the election of 1876, Hayes won by only one electoral vote and lost the popular vote by 254,235. Document 8). The 1877 Compromise was an agreement to take away Northern troops from the South. This agreement was made due to Tildens request so he would let Hayes win. The removal of Northern troops left freedmen without protection, and became easy targets for Southerners to attack. If Hayes wanted to win, he had to accept the request, so he took away the troops because if not, Tilden would have stayed in the power and done worse acts. In November 4 and 5, 1874, the front-page of New York Times published two headlines that announced how Democrats entered he House of Representatives and convert the Congress to be Democratic as well. (Document 5). These Democratic victories helped undermine Congress efforts to help freedmen by creating laws and acts that followed racism ideas. There was no more hope for the reconstruction at this point. Democrats were taking all the power and black men could not do anything anymore. Being free was not an option anymore, but a far away dream instead. Even though black people were given the opportunity to have some rights and equality, the Congress Reconstruction failed because events such as the creation of he Ku Kux Klan, the construction of the black codes, and the Compromise of 1877, kept their old beliefs of slavery and inequality.

Students That Suffer With ADD Should NOT Be Placed In Specialized Class

Should Students that Suffer with ADD Be Placed in Specialized Classes? Many adults and caregivers do not know what Attention Deficit Disorder (ADD) is and therefore do not know how to properly care for those children. They believe that because their children have ADD, they will not be able to learn or succeed in a normal class with other normal students. The truth is that only 1 out of every 35 students with ADD need additional help outside of the classroom because they are not sufficiently learning in it(Cowan). Many teachers and parents believe that putting children with ADD in specialized classes will help them to overcome their problems and become more successful in the classroom, but instead it will slow down their learning process, slow down their social skill development, and it will also teach them that they can use ADD as an excuse in other areas in their life(Child Development Institute). Attention Deficit Disorder is a disorder that is growing daily. In the 1920's only one out of every eight children, since then that number steadily increasing by the year, now one in every three children suffers from ADD(Cowan). Attention Deficit Disorder is a condition that causes people to have problems learning, behaving and even getting along with others. People that are diagnosed with ADD usually struggle with one or more of these common symptoms. The first symptom is inattention, which is where they will have problems with focusing in on one thing at a time, or paying attention for any amount of time. People that are inattentive have serious problems with distractions. This can severely affect a student in a classroom. Every little thing that goes on in that classroom gets their attention, whether it is from a child talking, som... ...Parent and Teacher Ratings of ADHD Symptoms: Psychometric Properties in a Community-Based Sample" Journal of Critical Child Psychology. 1991, Vol. 20, No. 3, Pages 245-253 Kraus, Jeanne.

Strength of Association

Strength of Association In research. Several principles have been shown to affect the strength of association between stimuli. Based on your own experiences in learning, provide an example of each of the following principles of association: contiguity, frequency, and intensity. Select one of your examples. Describe how a deferent principle of association might explain this example. Contiguity- Association by contiguity refers to the belief that our ideas, memories and experiences are link together when Is frequently experienced with the other, because tit contiguity the closer in time two events occurred. He more likely or strongly they would be associated. (Lieberman, 2012). When I was a little girl I would get into my mother's makeup and use her lipstick to draw on the bathroom wall. This upset my mother so she told me to stop doing this, but oddly enough I continued. As time went on she to spank me and say No when I did this, but when she would wake up and tint the bathroom walls clean tort my art work she would smile and say good girl. Then she would reward me with markers and other art supplies.I began to understand that if did what she said she would be happy and think I was a good girl and I would get art supplies for my good behavior. Frequency- With frequency this is an event or situation that would happen repeatedly. The frequency of association states that the more often two or more things occur together the more they will be associated together. An example that comes to mind Is that as a teen my mother would wake me up early In the morning everyday, which Is pretty hard, but In doing so she would get me a French vanilla cappuccino.I begin to feel every time I wake up n the morning I would get my lovely French vanilla cappuccino. I associated mornings and I guess my mother with a coffee beverage. Intensity- With intensity it involves stimuli. It is associations involving emotional or traumatic events. It occurs when I see places from the past that re mind me of a traumatic event. Trauma and memory form a generalization of fear as stimuli, which resembles those present during a traumatic event. (Lessee, Rabin, Heeler, Laughing, Garage, Pine, ; Grilling, 2010). When AAAS II years old my hip slipped out of place and AAAS in so such pain.I had been diagnosed for hip dysphasia. I was in tears form the pain that had increased over the previous year. By time got to the hospital was at my worst and I was put in the waiting room form six in the morning to 12 in the afternoon, before I was seen, then had x-rays done. By six in the evening I was fed up with the hospital and the staff and just wanted to go home, but I was forced to stay for emergency surgery the next mooring. After this situation I never really liked going to the hospital, because It reminds me of the pain I felt as a child.With my first example I would say it could fall into frequency, because the more I did one thing the more I did one thing such as drawing on the wall I would get spanked. So because of the frequency of the two together I begin to associate one with the other due to it happening do often. Reference Lieberman, D. A. (2012). Psychology of learning.

Theoretical Considerations Regarding Hazards And Risks Environmental Sciences Essay

The cognition of natural and technological hazards is of the extreme importance for carry oning hazard and impact appraisal surveies, every bit good as land usage planning and exigency response planning. This whole mechanism significantly contributes to the society ‘s sustainable development. For the overall comprehension of this issue, it is extremely relevant to specify the repeating constructs of this work, viz. jeopardy and hazard.The jeopardy constructTo get down with, a short ethimological analysis of the word â€Å" jeopardy † is necessary. This term has been taken by the Gallic from Arabic, where it means dice game ( Mac and Petrea, 2002 ) . Harmonizing to the Longman Dictionary of Contemporary English, 2010, † jeopardy † means â€Å" something that may be unsafe, or cause accidents or jobs † . In 1992, the United Nations International Decade for Natural Disaster Reduction secretariat published a multilingual lexicon so as to clear up and unite the significances of such footings. In this dictionary, jeopardy is defined as â€Å" a baleful event or the possibility for a phenomenon with destructive potency to look in a individual part and in a given period of clip † . Another definition is offered by the Grand Larousse Dictionary, volume V, cited by ZA?voianu and Dragomirescu in 1994: â€Å" accidental and, by and large, unforeseeable interface between two or more causal series, whose common dealingss are purely defined in every minute and whose comparative independency can merely be attributed to our ignorance and impotence † . Scheidegger, 1994, cited by ArmaAY , 2003 defined jeopardy as â€Å" the chance of rapid alteration of a system ‘s province or stable conditions † . In 1997 Grecu defined this construct as â€Å" the possibility that a potentially annihilating phenomenon appears in a certain period of clip and in a certain part. † In 1999 Octavia Bogdan and Elena Niculescu specify jeopardy as â€Å" a random phenomenon on a big graduated table, unpredictable, a deficiency of finding between clip and infinite, a qualitative lap, a threshold in the system ‘s development, downloading immense energy and doing upset, instability on the natural environmental development ‘s graduated table, in its manner towards a new province of equilibrium † . In 2000 Ozunu defines the construct under treatment as aˆza state of affairs with the potency of an accident † ; in 2001, BA?lteanu states that jeopardy is aˆza endangering event, stand foring the possibility for a potentially detrimental phenomenon to go on. † Harmonizing to him, harm to people, goods and the environment occur. Alexander, 2000, cited by Thywissen, 2006, defines hazard as aˆzan utmost geophysical event that can do a catastrophe. aˆsExtreme ‘ refers to an either positive or negative characteristic, harmonizing to the tendency it is related to. The jeopardy ‘s cardinal properties are: location, clip, magnitude and frequence. Many utmost phenomena are perennial in clip and predictable in footings of location. We define hazard as an utmost event arising from the biosphere, lithosphere, hydrosphere or atmosphere. † Mac, 2003, considers hazard as aˆzthe beginning of an utmost event with energy discharge in a certain minute and with a instead unforeseeable magnitude. In fact, jeopardy can be referred to as aˆza phenomenological class that refers to objects and phenomena ( air multitudes, H2O, lithomass, biomass, people, twisters, epidemics, temblors, avalanches etc. ) , to their actions ( inundations, clay flows, landslides, illness etc. ) every bit good as to their characteristics † ( Mac, 2003 ) . In 2003, Cardona, cited by Thywissen, 2006, offers another definition of the term: aˆzthe possibility for a natural and unsafe event to go on in a certain clip and infinite † . Generally, the construct of jeopardy is used to mention to a latent danger or to an external hazard factor of a system or exposed capable. A jeopardy is composed of three basic elements ( C. A. Ericson, 2005 ) : 1. Dangerous belongings – the basic beginning of the danger that creates the jeopardy, i.e. a unsafe energy beginning etc. 2. Initiation mechanism – the event that triggers or initiates the happening of the jeopardy, transforming the jeopardy from a inactive province to an active 1. 3. Target and menace – the individual, object, state of affairs vulnerable to damage caused by the materialisation of the jeopardy. These three elements compose the jeopardy trigon shown in figure 2.1: Figure 2.1 – The jeopardy trigon ( C. A. Ericson, 2005 ) The jeopardy trigon illustrates that all three above mentioned are interlinked. All three constituents are necessary in order to organize a jeopardy. The remotion of one portion of the trigon consequences in the riddance of the jeopardy, because it can non take to an incident. By extenuating the induction mechanism the chance of the incident to happen is reduced, and accordingly by extenuating an component of the unsafe belongings or mark and menace the badness of the incident will be reduced. These theoretical facets and categorization prove to be important in any undertaking refering jeopardy designation, extenuation, and hazard and impact appraisal. The basic construct of jeopardy theory can be summarized as follows ( C. A. Ericson, 2005 ) : Hazards are deterministic entities and non a random 1s ; Hazards are constituted accidentally in systems ; Hazards are predictable and hence can be controlled and prevented ; Hazards can be identified by their constituents ; Hazards will happen taking history of the constituents involved ; Hazards consequence in incidents. One of the term ‘s most recent definitions is the 1 offered in 2009 by the International Strategy for Disaster Reduction Secretariat: â€Å" a unsafe phenomenon, substance, human activity or status that may do loss of life, hurt or other wellness impacts, belongings harm, loss of supports and services, societal and economic break, or environmental harm. † As it can be noticed from the above-named definitions, jeopardy is characterized through certain parametric quantities, such as geographical location, strength ( magnitude ) , frequence and its chance to go on. In many of these definitions, one can detect the accent lies upon entropy, deficiency of determinacy and capriciousness ( Mac 2003 ) . In order to measure these phenomena ‘s possibility to go on, surveies refering their extreme values are considered. Furthermore, in all these definitions the construct of jeopardy has a instead negative intension, since it implies a certain grade of danger. Hazard can take the signifier of some remarkable phenomena or of some combines 1s, in footings of infinite and clip. Hazard appraisal purposes at identifying: the likeliness of a specified jeopardy to go on in the hereafter, in a certain period of clip, its magnitude and impact country ( Pine, 2009 ) . For the appraisal of certain jeopardies such as inundations, temblors and vents there are good established, predefined methods. The consequences of these ratings are extremely relevant in footings of lucubrating land usage planning schemes and in implementing accident bar steps.Hazard vs. hazardThe term â€Å" jeopardy † is closely related with the term â€Å" hazard † . Not few are the instances when confusion arises between the significances of these two constructs. This is why it is necessary to separate between them. Hazards are phenomena whose manifestations can barely be predicted and controlled. They have negative effects on population and on the environment. Imputing the characteristic of jeopardy to a natural or anthropic phenomenon is non conditioned by the production of mater ial harm or by the being of victims, but by the potency of these effects to go on. ( Baldea, 2007 ) . Merely when that jeopardy or phenomenon exceeds certain critical values, taking to material harm or casualties, does it go hazard. Therefore, a jeopardy is the menace that an event might go on and non the event itself. Should it impact a human community, to a certain extent, it becomes hazard. It must be mentioned that the term â€Å" hazard † is attributed assorted significances, being used in different contexts. Its definitions have societal, economic, political and environmental values. In order to better understand its deductions, a short diachronic analysis is necessary. To get down with, the term under treatment was foremost used in the fifteenth century, when it referred to the trade ‘s fiscal danger ( Proske, 2008 ) . Initially, this construct was associated with economic activities, being so used in the theory of chance and gaming. In the nineteenth century it is integrated in economic system, experiential doctrine and determination theory, whereas in the twentieth century it was used as political term in atomic engineering in order to gauge the degree of security that was acceptable for people. Until the 8th decennary of the old century constructs such as hazard, jeopardy and hazard direction were associated with natural phenomena. Hazard and natural or anthropic jeopardies analysis became an interdisciplinary kingdom of survey with its specific nomenclature merely in the last 30 old ages. The Longman Dictionary for Contemporary English, 2010, defines hazard as â€Å" the possibility that something bad, unpleasant, or unsafe may go on † . In 2007 ISDR defines hazard as â€Å" the combination of the chance of an event and its negative effects † . In 1999 Octavia Bogdan and Elena Niculescu define hazard as â€Å" the existent chance or possibility for a phenomenon to go on † . This event is someway expected and has negative reverberations, in response to which world can merely be inactive. Another definition is offered by Ozunu in 2000: â€Å" the chance that the existing jeopardy turns into an accident † . Alwang, 2001, cited by Thywissen, 2006, defines hazard as â€Å" the possible distribution of some known or unknown events. These are characterized by magnitude, frequence, continuance and history † . In the same twelvemonth, Peduzzi, cited by Brauch, 2005, considers risk aˆza step of possible losingss generated by a jeopardy of a certain magnitude, produced in a certain part and period of clip † . It must be stated that natural events can turn into social hazards when they surpass the immediate capacity of being counteracted or absorbed. They are, in most of the instances, utmost events. An utmost natural event is any event or series of events that shows a fleeting or durable fluctuation as compared to its common values. ( White, cited by ArmaAY , 2003 ) The widely accepted definition of hazard as the merchandise between the chance for an event to go on and the negative effects it may hold is expressed as follows: R= F x C ( Eq. 2.1 ) where: R- hazard ( losses/unit of clip ) , F- frequence of happening ( no. of events/unit of clip ) , C- effects ( losses/event ) . Hazard can besides be defined as â€Å" the chance of human exposure, of semisynthetic goods and of the environment to the action of a jeopardy of a certain magnitude and their exposure towards it † ( BA?lteanu, 2005 ) . For Petrea, 2009, hazard is â€Å" the possibility that some negative effects for human communities or losingss ( human lives, hurts, diminished agencies of subsistence, goods, harm of the environmental constituents ) appear as an interaction between natural or anthorpic jeopardies and territorial exposure † . This expression associates two distinguishable elements, viz. the jeopardy and the receiving system ( in most of the instances, a certain population ) . In most of the instances, the undermentioned expression is used: R= Hazard x Vulnerability ( Eq. 2.2 ) This underlines the relation between an event and its effects. In a certain country, the hazard is comparatively changeless. What differs is community exposure, in footings of its reaction to menaces or its degree of readiness to confront them. Harmonizing to the above-named expression, hazard may match to a high-frequency jeopardy and a low exposure or to a low-frequency jeopardy and high exposure. The disadvantage of this expression is that it does non see the population denseness, i.e. its exposure to hazard. Mitchell, 1990, cited by Brauch, 2005, completes this expression, sing jeopardy as a map of hazard, exposure, exposure and response: Hazard= degree Fahrenheit ( hazard ten exposure x exposure x response ) ( Eq. 2.3 ) where: hazard – the chance that negative effects appear, exposure – the size and characteristics of the open population, exposure – the potency of harm to bring forth and response refers to the enforced steps for hazard decrease. Another definition is given by Ozunu and Anghel in 2007: R = F x C x V ( Eq. 2.4 ) where: R – hazard ; F- frequence ; C – effects ; V- exposure ( – ) . The harm produced as a consequence of a catastrophe is really the consequence of the interaction among physical environmental factors ( clime, H2O, landscape etc. ) , population ( societal categories, civilization etc. ) and the built environment ( edifices, substructure etc. ) ( Mileti, 1999 ) . Therefore, jeopardy can be considered the pre-disaster state of affairs, when hazard does non look. A phenomenon ‘s development has three phases, more precisely: the jeopardy one, when merely hazard appears, the hazard phase, when jeopardy can impact human society and, eventually, the catastrophe. ( Alexander, 1993 ) In decision we can province that there are two types of hazards, viz. an acceptable one, where losingss are tolerable for the population and catastrophe, when losingss can non be tolerated by the local community.Categorization of jeopardies and hazardsAs antecedently mentioned, jeopardies and hazards are defined and characterized in multiple ways. In this chapter, a categorization is presented harmonizing to the most relevant features: beginning, effects, frequence, affected surface, etc.Categorization after beginningThe categorization of jeopardies harmonizing to their beginning is presented in table 2.1: Table 2.1 – Categorization after beginning ( BA?lteanu, 2005 ) :Natural jeopardiesEndogenousVolcanic eruptions, seismicityExogenousClimatic Cyclones, twister, storms, lightning, hail, hoar, drouth, etc. Geomorphologic Mass supplanting, eroding Hydrologic Flash-floods Oceanographic Rise of planetal ocean, El Nino Biological Epidemics, viruses, insect invasionsAnthropogenetic jeopardiesTechnologicalIndustrial, agricultural, transport accidentsHuman( Benedek, 2002 ) Social Poverty, unemployment, urbanisation, life style Medical Infectious, viral, chronic, degenerative diseases Demographic Emigration, population growing, aging of population Political Territorial, political differences2.3.2 Classification harmonizing to the manifestation mannerThe categorization of jeopardies harmonizing to their manifestation manner is presented in table 2.2 ( GoA?iu and Surdeanu, 2008 ) : Table 2.2 – Hazards categorization harmonizing to their manifestationViolent jeopardies– temblors – vents – severe storms, twister, etc. – local storms with hail etc. – catastrophic landslides, avalanchesHazards with progressive development– Mediterranean disturbances ( Mediterranean cyclones with retrograde development )Hazards with slow development– drouth – severe drouth – radiation and vaporization mists2.3.3 Categorization after continuanceHazards can besides be classified harmonizing to their temporal development. Harmonizing to ArmaAY , 2008 the categorization after the continuance of jeopardies is presented in table 2.3: Table 2.3 – Hazards categorization harmonizing to their continuanceWith sudden happening and rapid developmentEndogenous, tectonic jeopardies, sudden mass supplantings, flash – inundationsWith long continuanceTerrain debasement, drouths, desertification2.3.4 Categorization after affected surface, and continuance of effectsHazards can endanger assorted extents of a district. Within the affected surface the effects can prevail for assorted sums of clip. Harmonizing to Chardon, 1990 and Grecu, 1997 a categorization after the affected surface and the continuance of effects is presented in table 2.4: Table 2.4 – Hazards categorization harmonizing to affected surface and continuance of effectsCalamity typeAffected surfaceDuration of effectsExamplesGiga calamity100 – 510 mil. km2 several old ages volcanic eruptionsMega calamity1 – 100 mil. km2 several months big temblors volcanic eruptions tropical drouthsMeso calamity10.000 – 1.000.000 km2 several hebdomads – a few months volcanic eruptions temblors, cold moving ridges tropical stormsCalamity100 – 10.000 km2 a few hebdomads little temblors, twister exceeding rainsLocal phenomenaunder 100 km2 a few yearss – a few hebdomads landslides hail storms The present thesis focuses on the appraisal with optoelectronic engineerings of two major jeopardies from the above mentioned categorizations: Natural jeopardies – volcanic ash by active and inactive remote feeling Technological jeopardies – monitoring and patterning the impact of SO2 emanations associated with big burning workss.NATECH jeopardiesThis thesis focuses both on natural and anthropogenetic jeopardies individually. In order to develop efficient schemes for measuring hazards and impact, the NATECH ( natural jeopardies which trigger technological accidents ) rule is necessary to be considered when measuring either of the two above mentioned types of jeopardy. Current EU ordinances in the field of hazard appraisal and catastrophe direction ( European Commission, 2010 ) stress the necessity of a multi-risk and multi-hazard attack in all natural and anthropogenetic jeopardy and hazard surveies. Therefore, there is a turning involvement in the scientific community and among stakeholders sing natural jeopardies which trigger technological accidents ( NATECHs ) . NATECHs have important negative effects on human wellness, the environment and the economic system. The addition in the figure of such events is closely linked with the exponential technological development of the past decennaries, due to the variegation of engineerings, the turning figure of personal exposed, and the substances used in the technological procedures. The effects of NATECH events have become more terrible within this timeframe chiefly due to the exposure of the population life near these installations. Given these facts, there is an pressing demand for raising consciousness about bar and readiness steps refering these high effect low chance events ( Cruz and Okada, 2008 ) . Due to the complexness of NATECH events, their word picture is instead hard, and many NATECHs are analyzed and assessed as separate natural or technological events ( Embelton and Embelton-Hamann, 1997 ) . One needs to take into history that the effects of such an event differ in complexness from the effects of the two events taken individually ( Cruz and Krausmann, 2008 ) . Therefore, there is a demand for scientific research on the interactions and dealingss between natural jeopardies and technological accidents. Addressing NATECHs requires a combined attempt of industrial and technological hazard direction specializers working together with specializers concentrating on natural jeopardy probes. The specific features of a NATECH event ( Domino impacts, multiple effects ) need specific steps for the bar, response and recovery after such an event. An integrated hazard and impact direction scheme must include the possibility of NATECHs to happen, and necessitate specialised planning for extenuation, response, and recovery ( Ozunu et al. , 2011 ) The Activities Report On the Collaboration Agreement between the International Strategy for Disaster Reduction of the United Nations and the Directorate General Joint Research Center of the European Commission proposes a scheme for the extenuation of NATECH events by: iˆ Industry hazard direction specifically turn toing the possible impacts of natural jeopardies on technological installings. Additional hazard direction processs ( Figure 2.2 ) in order to cut down the exposure to NATECHs: the usage of excess safety systems, natural jeopardy resistant designs, guidelines to inform industry about NATECH planning, and strategic arrangement of risky substances inside a unit. Figure 2.2 – Catastrophe Management processs ( Torok et al. , 2009 ) Efficient Emergency planning, including bar and extenuation, and response planning for NATECHs at all degrees of authorities. The purpose of the Risk Analysis procedure is to cut down uncertainnesss by increasing safety degrees by developing more efficient Emergency Plans, offering immediate determinations, detailed, accurate and steady instructions ( ( Torok et al. , 2009 ) iˆ Land usage planning, as an of import tool for setting-up insularity margins in order to protect occupants populating near risky installations. ( Christou et al.,2006 quoted by Torok et Al. 2011c ) . Article 13 of the SEVESO III Directive ( Directive 2012/18/EU ) provinces that: â€Å" Member States shall guarantee that the aims of forestalling major accidents and restricting the effects of such accidents for human wellness and the environment are taken into history in their land-use policies or other relevant policies † Information and instruction of the populace, authorities bureaus and all stakeholders involved in exigency direction, including decision-makers. iˆ Public engagement in NATECH hazard decrease planning, in order to better understand the perceptual experience of the degree of the NATECH hazard and the degree at which this hazard is considered acceptable ( Ozunu et al. , 2011 )Qualitative and quantitative methods for placing jeopardies and measuring hazardsA systematic designation of possible environmental impacts atmospheric pollutants have, every bit good as a strict analysis of their magnitude is required. The intent of such a procedure can be divided in two major issues, on one manus to bring forth quantitatively accurate appraisal of peculiar hazard and a comprehensive list of possible environmental impacts, and on the other manus produce a principle for doing public policy determinations that is both good reasoned, and recognized as legitimate and acceptable by the socio-economical factors. A complex environmental impact appraisal ( EIA ) and hazard appraisal ( RA ) methodological analysis requires assorted sets of informations about beginning footings, emanations, imissions, exposure, local weather forecasting, terrain informations etc.. Most of the air scattering theoretical accounts have been developed for the anticipation of lee concentration of air pollutants and for the appraisal of short-run and medium-term effects of these pollutants. The quality of consequences obtained utilizing these patterning systems depend largely on the versatility and quality of input informations and the right pick of the theoretical account ( Torok et al. , 2011a ) . In instance of EIA surveies, the medium-term effects appraisal requires emanation and meteoric informations for several months in order to obtain a realistic distribution of the largely contaminated countries. The consequence of the complex terrain on the air motion in the commixture bed is important. Therefore the meteoric information for the modeling period should be calculated sing the air flow above the complex terrain. For RA, the appraisal of immediate effects of ague exposure requires on-site informations for a short clip period. These informations sets must incorporate information about emitted substances ( type and concentration ) every bit good as real-time local meteorological informations, which along with terrain informations can be used in a rapid environmental and risk appraisal, which is a valuable tool for on-site exigency planning in instance of accidental or deliberated releases of toxic substances in the ambiance ( Torok et al. , 2011a ) . In the field of hazard analysis and hazard appraisal there are differences of sentiment sing the usage of qualitative or quantitative hazard analysis methods. The qualitative-quantitative factor is the basic belongings of jeopardies analyses methods. Most of the analysis methods are developed in order to place jeopardies and to find the hazard of that jeopardy turning into an accident. For finding the accident hazard of the identified jeopardy, a methodological analysis for the word picture of chance and magnitude parametric quantities must be used. There were developed both qualitative and quantitative methods, which are successfully used, each methods holding its specific advantages and disadvantages ( Torok et al. , 2011a ) .Qualitative methods used in jeopardy analysisA qualitative analysis implies the usage of qualitative standards, utilizing different classs for parametric quantities separation, with qualitative definition which set up the graduated table for each class. Besides, qualitative determinations are made, based on the field experience, in order to delegate elements into classs. This attack is subjective, but it allows a higher generalisation grade, being less restrictive.2.5.1.1 Designation of jeopardiesThe designation of technological jeopardies is the basic measure in hazard appraisal procedure. Hazards appear in the industry all the clip, due to the procedure and runing conditions of the installings and the physical, chemical and toxicological belongingss of the substances used in these procedures. This is why it is extremely of import to place the substances ‘ risky belongingss and the operating conditions that put at hazard these procedures, the series of events that may take to the materialisation of a jeopardy. In order to develop an in-depth survey of jeopardies and hazard analysis, the risky belongingss of the substances must be identified and assessed in order to find conditions or non they pose a jeopardy to human life, the environment of the technological procedure. From a qualitative point of position this can be achieved utilizing checklists. A comprehensive checklist used in the appraisal of jeopardies and hazards posed by substances is presented in table 2.5: Table 2.5 – Hazardous belongingss of substances- Checklist ( Hyatt, 2003 )TypePropertyGeneral belongingssMolecular construction Freezing point Melting point Vapour force per unit area Boiling temperature Critical force per unit area Critical temperature Critical volume Density Specific heat Viscosity Thermal conduction Fluid denseness Latent vaporisation heat Dielectric invariable Electric conductionFlammabilityExplosion/ Flammability bounds Explosion threshold Auto ignition temperature Minimal ignition energy OverheatingCorrosionCorrosive for building stuffs Incompatibility with other stuffsPolymerizationDecompositionFeatures of polymerisation Features of decomposition Features of hydrolysisImpuritiesImpurities in equipment stuffs Impurities in substanceChemical reactions, detonationsHeat of formation Heat of decomposition Combustion heat Thermal stableness Resistance to impact Potential energy jeopardiesToxicityExposure bounds: IDLH ; ERPG1-2-3 ; AEGL 1-2-3 ; LC50 and LD50 Exposure effects ( inspiration, consumption, tegument and oculus contact ) Effectss of long-run exposure with little sums Warning bounds ( odor threshold )RadiationRadiation bounds I ± , I? , I? atoms Material toxicity It must be stated that stuff toxicity depends on a series of physical and chemical factors, in the type of contact and on the interaction of substances with beings. The ways in which this penetrates the organic structure are assorted, viz. unwritten ( through the oral cavity, in the tummy ) , cuticular ( toxicity enters the tegument ) or by agencies of inspiration ( through the respiratory system ) . The harmful belongingss of risky substances can be divided into the undermentioned classs ( Ozunu and Anghel, 2007 ) : acute toxicity ( really toxic, toxic, harmful, annoying ) specific belongingss ( allergic, carcinogenic, with consequence on reproduction or familial consequence ) with harmful impact on the environment Whereas the first two classs mentioned supra have direct inauspicious consequence on wellness, the last one acts indirectly on human existences by damaging the environment. The harmful actions start when little sums of substances appear in the organic structure ; should larger sums appear, they can take to one ‘s decease. The most normally used indexs to find substance toxicity are ( Torok et al. , 2011c ) : medium deadly dose- LD50 is the dosage at which half of the experimental population of animate beings ( or worlds, should human deceases be registered ) dice. LD50 index at consumption and at the skin degree is shown in milligram ( mgs ) of substance per kg of animate being organic structure, taking into history a individual disposal. the medium deadly concentration – LC50: concentration for inspiration is measured in mgs of substance per litre of air breathed or in volumetric parts per million -ppm ( exposure clip differs depending on substance toxicity ) the immediate unsafe concentration for life and wellness – IDLH is inspiration with irreversible effects on wellness These bounds of concentration are used as indexs in both the US and the EU statute law ( NIOSH, 2012 ) . The bounds of toxicity for a series of substances are set in the Dangerous Substances Directive 67/548/ EEC. They are grouped harmonizing to some classs presented below. Each type of danger has a hazard phrase ( Rphrase ) consisting of a figure and of the appropriate hazard description ( Ozunu and Anghel, 2007 ; Directive 67/548/ EEC ) . Table 2.6 – LD50 ( unwritten )ClassLD50( mg/kg )SymbolRphraseVery toxic& lt ; 25 T+ R26, R27, R28Toxic25 – 200 Thymine R23, R24, R25Harmful200 – 2000 Xn R20, R21, R25 The current thesis focal points on two major jeopardies, natural 1s, with a instance survey on volcanic ash, and anthropogenetic 1s, with instance surveies on S dioxide ( SO2 ) . Sing volcanic ash, the most serious jeopardies can be associated with its: caustic belongingss on stuffs, i.e. aircraft engines, windscreens, etc. , runing point, the volcanic ash runing inside the turbine due to the high temperatures, and so solidifies in the ice chest parts of the engine s. denseness, the denseness of volcanic ash is comparatively high, dry ash being up to 5 times, wet ash about 20 times denser than snow. This fact represents a major jeopardy to edifices when ash accumulates on the roofs in sufficient measures, taking to prostrations. In the instance of SO2, the major jeopardies are associated with:Quantitative methods used in hazard appraisalQuantitative analysis implies the usage of numerical or quantitative informations and provides quantitative consequences. This attack is more nonsubjective and more precise. It must be mentioned that the quantitative consequences can be extremely affected by the preciseness and cogency of the input parametric quantities. Therefore, the quantitative consequences within the hazard analyses should non be taken into consideration as exact Numberss, but as estimations, with a variable graduated table depending on informations quality ( Torok, 2010 ) .2.4.2.1. ModelingThe representation of world through mold is extremely relevant, since it offers one the possibility to analyze and analyze systems in footings of mathematics and technology. It must be mentioned that a system consists of a set of elements that interact with one another within some bounds. Furthermore, this system has a specific behavior. These bounds are really the 1s that separate the system from the other 1s. These theoretical accounts can be divided into two classs, viz. physical and abstract ( fanciful or mathematical ) theoretical accounts. With respect to the physical theoretical accounts, they describe the system from a physical point of position, utilizing the physical Torahs that apply upon the system under treatment. The mathematical theoretical account of a system describes it in footings of mathematical equations, utilizing simplifying hypotheses. Abstractization works in both ways, i.e. from object to its representation ( theoretical account ) and so back to world. Still, it must be stated that this theoretical account does non picture world all the clip ; it tries to be as closer to it as possible. The more complex a system is, the more complicated the theoretical account becomes. In this context, the purpose of patterning systems and processes utilizing the computing machine is to make a theoretical account that contains a description realistic plenty for the given application. The basic stairss for the accomplishment of a mathematical theoretical account are as follows ( Savii and Savii, 2000 ) : job designation and the pick of variables building of mathematical dealingss among variables utilizing simplifying premises the purchase of information sing the size, importance and interrelatednesss for each variable under treatment the choice of input signals ‘ parametric quantities constitution of province variables proof of premises and dealingss utilizing the right theoretical account harmonizing to the state of affairs.2.4.2.2. SimulationWith the development of information engineering and computation equipment, the scrutiny of theoretical accounts utilizing simulations has become possible. Simulation allows proving those systems ‘ functionality theoretical accounts that have yet to be or are presently in design stage. Simulation is the lone possibility of analyzing the dynamic behavior of such a theoretical account. Discrete simulation, utilizing theoretical accounts of distinct systems, is of great aid for projecting production systems, where issues of optimisation appear ( Savii and Savii, 2000 ) . In the present thesis we focus chiefly on the mathematical mold of the gas pollutants ‘ scattering in the ambiance. Beginning theoretical accounts are used to specify the quantitative emanation scenario of substances by gauging their flow rate, the scattering of substance after release. Dispersion theoretical accounts turn the end products from beginning theoretical accounts into isoconcentration curves specifying concentration countries and cipher the development of concentration in clip. The mass conveyance of molecular-scale fluid occurs through diffusion, with a changeless diffusion velocity throughout its motion. However, unstable scattering is a procedure different from molecular diffusion, since the mass conveyance occurs at assorted scale lengths of the disruptive motion. Disruptive scattering is much more efficient than molecular diffusion. The scattering rate is non changeless ; it depends on the size of the whirl and of that of the cloud of spread pollutant. These whirls can be of different sizes ; on a big graduated table, they determine the motion of the pollutant cloud, whereas on a little graduated table they contribute to its dilution. The energy and size of these whirls determine gas plumes scattering. Their continuance, length and strength are the chief factors that influence this procedure. The mathematical mold of gas pollutants in the ambiance is based on equations of mass, energy and impulse preservation. Such an equation must be established for each pollutant. It represents the fluctuation of atoms ‘ denseness in clip and infinite. From these equations one can acquire a complex system of equations that can be solved by agencies of numerical methods, obtaining the existent behavior of concentration in clip and infinite. A literature reappraisal reveals two chief methods used for picturing the behavior of pollutants released into the ambiance, viz. the Eulerian formalism and the Lagrangian 1. Both methods are used to depict the statistical belongingss of pollutant concentration. The Eulerian formalism starts from ciphering fluid speeds in the ten, Y and omega waies, measured in fixed points in the fluid under treatment. Input information is comparatively easy to obtain from the measuring or mold of discharges, but work outing the mathematical equations system can be really complex, ensuing in inaccurate solutions. Dispersion coefficients can be retrieved utilizing the Pasquill-Gifford graduated table ( Pasquill, 1961 ) . After this, the imission map for a beginning point and meteoric scenario can be developed. The Lagrangian formalism uses the statistical belongingss of some fluid atoms that move passively, freely. As compared to the Eulerian formalism, the mathematical equations system is easier to work out, therefore it is computationally really efficient, and merely the fraction of the sphere really involved in the scattering is simulated. Disruptive procedures are included in the theoretical account in a more natural manner, and there is no important numerical diffusion ( Stohl et al. , 2005 ) . Still, the method ‘s pertinence is limited by the troubles encountered when finding the statistics of fluid atoms. The Lagrangian formalism is applicable upon long-distance scatterings, when the complex topography influences the flow of air-pollutant multitudes. Although the scattering procedure is a typically Lagrangian one, about all information available refering the ambiance are based on Eulerian measurings. Therefore, a relation between the Eulerian belongingss and the Lagrangian 1s is ( widely ) accepted ( Sandu et al. , 2004 ) .

Bargaining Power of Customers Essay Example

Bargaining Power of Customers Essay Example Bargaining Power of Customers Essay Bargaining Power of Customers Essay Bargaining Powers of Customers Porters’ competitive factors theory is a framework for industry analysis and corporate strategy development. It draws an overview picture that industry rivalry is affected by five main forces, which are bargaining powers of customers, bargaining powers of suppliers, threat of new entrant and threats of substitute products. Relating Porters’ thesis and the topic of managing customers, element named bargaining powers of customers, which can be briefly understood as the ability of customers putting to put firm under pressure, is the most important.To be more details, customers who finally consume products has bargaining power refer to the potential of buyers to bargain down the prices charged by the firms in the industry or to increase the firms cost in the industry by demanding better quality and service of product. Strong customers can extract profits out of an industry by lowering the prices and increasing the costs. (Porter, 2008) However , in the 21st century economic context, customers do not only want low price but they also desire to bargain on other aspects such as delivery, supports and performance.Firgure 1: Porters’ Five Competitive Factors Applying Porters’ model to Microsoft, as a company provide software, Microsoft’s customers always demand convenience package of product with affordable price, provision of products, technical supports, products’ performance also efficiency, especially for the group of customers are business as well as enterprises, which can considered as strong customers having direct influence to the company (may be stock price on the market).As is known, human beings want is unlimited so it is easy to understand that customer can bargain on price and quickly delivery at the same time due to the century of technology also faster and faster pace of life. In addition, some customers totally concentrate on requirements of products’ quality and effectiveness in order to minimise the repeating operating expense. Unsatisfactory customers can boycott Microsoft, public bad feedbacks resulting in the customer loss, being defeated by competitors.Microsoft understand the importance of customers so it has provided many programmes with aim to fulfil customers’ needs and make a good deal with them. Customer and Partner Experience (CPE) is one of the most successful customers supporting program of Microsoft. Every year, this team conduct a survey world wide, namely Global Research survey, so as to update customers’ taste as well as expectation. Aiming at raising customers’ opinions, CPE team drives all account managers combining with sales roles to request customers fill out a form.Basing on these examinations, Microsoft sum up a net satisfaction points and put them as goals to improve in the next year. At last but not least, understanding the need of customers on immediately communicate with company, Microsoft have made many direct connection ways available such as hotline (Australian hotline is 13 20 58), social media (Facebook, Twitter), particular email addresses for each different product and Microsoft Connect. With a wide range of instantly communicate, customers can easily get support from Microsoft and their problems can be quickly solved.
