How do we know if a patient is competent? health care. Due to patients in a weakened state being patients the truth vulnerable in a physical and mental state. Why rules aren"t enough: rules may presuppose that you"re already. Development of scientific-based medicine familiar with health care ethics. Who should decide when the sale of human organs be legalized? contingencies that may arise. You must have your own capacity for moral reasoning to fall back on. Who should decide when to experiment on: ultimately everyone is responsible for their humans? own actions, you may be the one to make the rules. Emergence of large health care institutions and bureaucracies. Ethics is just a part of health care. How should scarce health care resources be. Ethics play important role in medicine and distributed healthcare. To be a complete healthcare professional, publicly funded you need basic grounding in ethics. Ethics is subjective hard to argue. Humans forming irrational beliefs in certain situations.

5.4 .. BIO Injuries to the Spinal Column. In the treatment of spine injuries, it is often necessary to provide tension along the spinal column to stretch the backbone. One device for doing this is the Stryker frame (Fig. E5.4a). A weight W is attached to the patient (sometimes around a neck collar, Fig. E5.4b), and friction between the person's body and the bed prevents sliding. (a) If the coefficient of static friction between a 78.5-kg patient's body and the bed is 0.75, what is the maximum traction force along the spinal column that w can provide without causing the patient to slide? (b) Under the conditions of maximum traction, what is the tension in each cable attached to the neck collar? Figure 5.4

When the heart pumps blood into the aorta, the pressuregradient-the difference between the blood pressure inside the heartand the blood pressure in the artery-is an important diagnosticmeasurement. A direct measurement of the pressure gradient isdifficult, but an indirect determination can be made by measuringthe Doppler shift of reflected ultrasound. Blood is essentially atrest in the heart; when it leaves and enters the aorta, it speedsup significantly and-according to Bernoulli's equation-the pressuremust decrease. A doctor using ultrasound of 2.5 MHz measures a 5400Hz frequency shift as the ultrasound reflects from blood ejectedfrom the heart.
Part A
What is the speed of the blood in the aorta? Assume that the speedof sound in human body is 1540 m/s
A:1.7 m/s
***Part B
What is the difference in blood pressure between the inside of theheart and the aorta? Assume that the patient is lying down and thatthere is no difference in height as the blood moves from the heartinto the aorta.

Hi this is the introduction that I have written for my poster. Myposter is on the following URL (please have a look!).

Please correct the introduction for any scientific or grammaticalerrors and give me your suggestions about this section as well asthe overall poster. Thanks

This is very important so if you are not good at it pleasedon't answer.

Here is the introduction :

Have you ever thought about why would thrilling rides getyou excited, make your heart racing orsometimes even make you start screaming from the depths of yourcore, forming a bead of sweat on your forehead?

Well, the answer lies in physics. These rides demonstratevery good examples of the physics laws and concepts involved innature and their affect on us in real life applications.

Height, weightlessness, high velocity, hugeacceleration, the sudden impulse and themomentary change in momentum, the work being done and the suddenchange in energy are all factors that contribute inmaking a thrilling ride an exciting one. Those factorsmake adrenalin concentrations in our body system increasecausing higher blood pressure thus stimulating theheart.. They also make the rider in a lot ofuncertainty and unexpected visual cues.

An example of a thrilling ride is the Giant Drop which isa freefall ride involving the drawing of an eight seat carriage bytwin cables to the top of the tower. After one minute full ofanxiety, the riders are plummeted down a height of 39 stories(almost 115m) then brought to a halt within meters from the groundby a sophisticated magnetic braking system.
