P1, Parkinson’s disease Nature of disaster
Causes, Parkinson’s disease is caused by a loss of nerve cells in the part of our brain and this is called substantia nigra. Also the nerve cells in our brain are responsible for producing a chemical and that is called the dopamine. However the dopamine acts like a messenger between the parts of the brain and then the nervous system that helps to control and to co-ordinate body movements. If our nerve cells gets damaged then the dopamine in our brain is reduced, and this shows that the part of our brain controlling movement will not work as before. It will cause the movements and abnormal to become slow. It is not known why the loss of nerve cells associated with Parkinson's disease occurs, currently; it is …show more content…
This will give you troubles when you are trying to move your limbs, another symptom is that Slowness of movement is the common in people with Parkinson’s disease for example; this can become more of an effort to walk or to get up out of a chair or anything.

...Osteoporosis P1 Explanation of the condition Osteoporosis is a bone condition in which the bones become very brittle and weak, usually from a lack of vitamin D and calcium in the bones. Osteoporosis increases the risk of a bone fracture. It is a condition that affects almost 3 million people who live in the UK. Over 300,00 people who have osteoporosis are in hospital every year from fractures caused by osteoporosis. (http://www.nhs.uk/conditions/Osteoporosis/Pages/Introduction.aspx/accessed on 13th December 2015) https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcRlYCA4Mm1Mtu_adX98fE_fTtEqOFOmKhbEwE-Jvl4kOE2Tj03cjg Causes of the physiological disorder When we are children, our bones tend to grow and repair very easily but this works but the density of our bones continues until we reach our late twenties or early thirties. Then our bone density will start to decrease. Bone loss tends to happen when women start the menopause because they stop getting their periods. When women stop getting their periods, the level of oestrogen in their body stops and people need it in their body to have healthy bones. This means women are more likely than men to develop osteoporosis or suffer from a fracture. In men, it has been known that the risk of them developing osteoporosis relates to the low levels of testosterone in their bodies which they need for healthy bones. Although bone loss is the main cause of osteoporosis, there are many other factors that increase your risk of developing...

Income and Substitution Effect

...Substitution Effects — A Summary What are Income and Substitution Effects? When the price of q1, p1, changes there are two effects on the consumer. First, the price of q1 relative to the other products (q2, q3, . . . qn) has changed. Second, due to the change in p1, the consumer's real income changes. When we compute the change in the optimal consumption as a result of the price change, we do not usually separate these two effects. Sometimes we might want to separate the effects. The Substitution Effect is the effect due only to the relative price change, controlling for the change in real income. In order to compute it we ask what is the bundle that would make the consumer just as happy as before the price change, but if they had to make their choice faced with the new prices. To find this point we consider a budget line characterized by the new prices but with a level of income such that it is tangent to the initial indifference curve. In the diagram on the next page, the initial consumer equilibrium is at point A where the initial budget line is tangent to the higher indifference curve. Consumption at this point is 11 units of good 1 and 8 units of good 2. After an increase in the price of good 1, the consumer moves to point E, where the new budget line is tangent to the lower indifference curve. Consumption of good 1 has fallen to 4 units while consumption of good 2 has increased to 10 units. The substitution effect is the movement from point A to point G. This point is characterized...

...the spaces provided. Be brief and precise. Question 1: Refer to Figure 6 below Figure 6 [pic] a. Equilibrium price and quantity before trade would be ▪ Price = $14; ▪ Quantity = 600 b. The price and domestic quantity demanded after trade would be ▪ Price = $ 18; ▪ Domestic quantity demanded = 400 c. After trade domestic production would be ▪ Domestic production = 800 d. How much of this product would be exported after trade ▪ Amount exported = 800 - 400 = 400 e. Calculate the consumer surplus before trade ▪ CS before trade = (26-14)*600*0.5 = 3600 f. Calculate the consumer surplus after trade ▪ CS after trade = (26-18)*400*0.5 = 1600 g. Calculate the producer surplus before trade ▪ PS before trade = (14-3)*600*0.5 = 3300 h. Calculate the producer surplus after trade ▪ PS after trade = (18-3)*800*0.5 = 6000 i. Calculate the net effect of trade on total surplus ▪ Net effect of trade = change in PS - change in CS = (2700- 2000) = 700 Note: An alternative and correct way to compute this is to calculate the area of the triangle showing the gain in surplus. This area is (18-14)*400*0.5 = 800. This is different from 700 because of a slight mislabeling of the diagram. Therefore award the full points for this answer as well. Question 2 a. What are...

...Supply, Demand and Equilibrium in Linear Equation The quantity demanded is the amount of a good that consumers want to buy at a given price, holding constant all other factors that influence purchases. The demand function shows the mathematical relationship between the quantity demanded , the price of the product, and other factors that influence purchases. A demand curve plots the demand function, again holding constant other factors. The quantity supplied is the amount of a good that firms want to sell at a given price, holding constant all other factors that influence firms’ supply decisions. The supply function shows the relationship between the quantity supplied, the price of the product, and other factors that influence the number of units supplied. An equilibrium exists if no market participant wants to change its behavior. In a market, equilibrium occurs at the price and quantity where the demand curve and the supply curve intersect. Example Problem: :SUPPLY AND DEMAND .AT $1.40 PER BUSHEL,THE DAILY SUPPLY FOR OATS IS 850 BUSHELS AND the daily demand is 850 bushels.when the price falls to $1.20 per bushel,the daily supply decreases to 350 bushels,and the daily demand increases to 980 bushels.assume that supply and demand equation are linear A-find the supply equation. B-find the demand equation. C-find the equilibrium price and quantity. Let x1 = 120 cents Let x2 = 140 cents For the supply equation: Let y1 = 350 Let y2 = 850 For the Demand equation:...

...computer It estimates that it will take competitors at least two yeas to produce equivalent products. The demand function for the computer has been estimated to be P = 2,500 - .0005Q The marginal (and average variable) cost of producing the computer is $900. a. Compute the profit-maximizing price and output levels assuming Pear acts as a monopolist for its product. Answer: The monopolist would equate marginal revenue (MR) with marginal cost (MC) Total revenue (TR) = P*Q = 2500Q-Q^2 MR = dTR/dQ = 2500-2Q We have MC = 900 So MR= MC implies 2500-2Q= 900, implies monopoly output Q* = 800 (in units of 100) And monopoly price P = 2500-0.0005*800 = 2499.6 b. Determine the total contribution to profits and fixed costs from the solution generated in part (a). Answer: Total profit = P*Q-MC*Q = 800*2499.6 900*800 = $ 1279680 (in units of 100) Pear Computer is considering an alternative pricing strategy of sliding down the demand curve.

... a) What is the mean or expected number of customers that will arrive in a five-minute period? The expected number is of 0.4*5 = 2 customer is a five-minute period. b) Assume that the Poisson probability distribution can be used to describe the arrival process. Use the arrival rate in part (a) and compute the probabilities that exactly 0, 1, 2, and 3 customers will arrive during a five-minute period. The probabilities of the described scenarios are as follows: P0=20e-20! P0=0.135335283 P1=21e-21! P1=0.270670566 P2=22e-22! P2=0.270670566 P3=23e-23! P3=0.180447044 c) Delays are expected if more than three customers arrive during any five-minute period. What is the probability that delays will occur? This probability can be expressed as the probability of more than 3 customers arriving during the five-minute period, which can be computed as following: P(x > 3) = 1 – P(x ≤ 3) P (x > 3) = 1 – 0.85712346 P(x > 3) = 0.14287654 Thus, there is a 14, 29% probability of expected delays in five-minute period.

...Chapter 6: CPU Scheduling • • • Basic Concepts Scheduling Criteria Scheduling Algorithms Operating System Concepts 6.1 Basic Concepts • Maximum CPU utilization obtained with multiprogramming. • CPU–I/O Burst Cycle – Process execution consists of a cycle of CPU execution and I/O wait. – Example: Alternating Sequence of CPU And I/O Bursts – In an I/O – bound program would have many very short CPU bursts. – In a CPU – bound program would have a few very long CPU bursts. Operating System Concepts 6.2 1 CPU Scheduler • The CPU scheduler (short-term scheduler) selects from among the processes in memory that are ready to execute, and allocates the CPU to one of them. • A ready queue may be implemented as a FIFO queue, priority queue, a tree, or an unordered linked list. • CPU scheduling decisions may take place when a process: 1. Switches from running to waiting state (ex., I/O request). 2. Switches from running to ready state (ex., Interrupts occur). 3. Switches from waiting to ready state (ex., Completion of I/O). 4. Terminates. • Scheduling under 1 and 4 is nonpreemptive; otherwise is called preemptive. • Under nonpreemptive scheduling, once the CPU has been allocated to a process, the process keeps the CPU until it releases the CPU either by terminating or by switching to the waiting state. Operating System Concepts 6.3 Dispatcher • Dispatcher module gives control of the CPU to the process selected by the short-term scheduler;...
