Document Summary

150 g population is born with only 1 kidney but live normal lives. After blood flows around, it is collected back in the venous system & backtracks the way it came. Each kidney contains ~1 million subunits called nephrons. No proteins in the bowman space fluid = no oncotic pressure: power to pull water back in is because of the [proteins] Figure 14. 08forces involved in filtration(oncoticpressure)glomerular capillary wall(filtration barrier)visceral glomerular epithelial cells (podocytes)gbmendothelial cells. Gfr: the volume of fluid filtered from the glomeruli into bowman"s space per unit time. Normal gfr for a 70kg person is 180l/day. Normal plasma volume is ~3. 5l plasma is filtered 51 times per day at glomeruli. Filtered load: the total amount of any freely filtered substance. Net filtration pressure: only physiologically-significant method, decreased gfr. Measure of kidney failure: increased gfr. Membrane permeability and surface area available for filtration: only relevant in pathological conditions.

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.

It is currently popular for automobiles to use 10% ethanol / 90%gasoline mixtures (âgasoholâ) as fuel. According to popularconsensus the main benefit of gasohol use is that it âreduces ourdependence upon foreign oil.â We test this assertion by making someelementary calculations. Our analysis will unrealistically ignoreengine maintenance issues associated with older automobiles (suchas gasket and seal hardening), added fuel consumption necessary toproduce grain used as a feedstock in ethanol production,incremental food price increases associated with a reduction ingrain stocks, and many other effects. Gasohol use typically reducesaverage fuel economy by approximately 15% and effectively leavesfuel prices unchanged. This article further debates the wisdom ofethanol use and may be of interest outside the problems:

These concerns and problems have been strongly influenced byconversations with Dr. H.J. Harmon, of the OSU physicsdepartment.

2. Consider a 14.2 mpg 1991 Ford F150 driven 761 miles. Calculatethe pure gasoline consumption of this truck when: a) usinggasoline, and b) when using gasohol (with its attendant economyreduction). Determine the total CO2 emissions for each fuelassuming all fuels produce 20 lbs of CO2 per gallon. Comment uponthe wisdom of using gasohol versus pure gasoline in this vehicle.

This is the introduction of my scientific poster presentationplease proofread it grammatically and scientifically and give meany suggestions you have! Thanks.

Have you ever thought about why would thrillingrides get you excited, make your heart racing oreven make you start screaming from the depths of your core, forminga bead of sweat on your forehead?

Well, the answer lies in physics. These rides demonstrateparticularly good examples of the physics laws and conceptsinvolved in nature and their effect on us in real-lifeapplications.

Height, weightlessness, high velocity, huge acceleration,centripetal force, impulse and the momentary change in momentum,the work being done and the change in energy, are all factorsthat contribute in making a thrilling ride an exciting one. Thosefactors cause adrenalin rush which leads to a higher bloodpressure thus stimulating the heart. They also put the riderin a lot of uncertainty and unexpected visual cues.

An example of a thrilling ride is the Giant Drop which isa free-fall ride involving the drawing of an eight seat carriage bya cable to the top of the tower. After one minute full of anxiety,the riders are plummeted down a height of 39 stories (almost 115m)then brought to rest within meters from the ground by asophisticated magnetic braking system.
