Because we synthesized the two most common kidney stones‚ calcium oxalate and calcium phosphate‚ we will focus on those two in the discussion of formation‚ treatment‚ and prevention. Calcium stones like calcium oxalate and calcium phosphate stones form when urine is “supersaturated with the constituent ions that comprise the stone” (Figge). This means‚ when urine is supersaturated with calcium and oxalate ion that type of stone is more likely to form. This supersaturation results from the ionic activity

Ownership of Bodily Fluids and Organs: Do we have the right to sell Organs and Fluids? The advancement of modern technology and our continual progress in medical sciences have made it necessary to debate this topic. There are many cases where it is unclear as to whom has the property rights of bodily fluids‚ cells‚ or organs. These questions of ownership tend to surface in cases where these products are no longer located within a person’s body. The necessity to delegate ownership

Midterm Exam II Solution‚ ME 342 Fluid Mechanics (Spring 2013) 1. Consider a steady‚ incompressible‚ y=+h b viscous flow of viscosity due to y a pressure gradient x inside a channel of two fixed u=u(y) plates at a distance of 2h‚ as shown in the figure. Neglect a gravity effect. The channel width y=h b is W and it is very long compared to the channel length L (i.e.‚ W>>L) so that it is still valid to assume that the channel flow is a two-dimensional plane flow ( ) and an axial flow (v = w = 0)

Kidney plays an important function in regulation the concentration of sodium and potassium in blood. A steroid hormone called aldosterone is secreted by the adrenal cortex in respond to rennin secreted by the kidney cells to stimulate potassium excretion by active reabsorption of sodium in distal and collecting ducts. Aldosterone increase active secretion of potassium in distal convoluted tubules and also stimulates the reabsorption of sodium on collecting ducts. Antidiuretic hormone also helps to

This assignment was made to explain and find the truth about the concept of work life balance which is meaningful for the worker. As many researcher and people arguing about this concept‚ The author comes to the decision which is disagree that work life balance is important for the worker. As a concept‚ the work life balance can be said has a great effect for the worker‚ but in real life work life balance was difficult to maintain. Not all worker can contribute their time only for working without

Importance of balance of trade Balance of trade data is a very important piece of understanding the global puzzle of international trade‚ and thus‚ forex. Much like an income statement‚ balance of trade data clearly defines whether a trade deficit or trade surplus is in play. Why Balance of Trade Matters Balance of trade data shows the imports and exports of goods and how a country competes in a global marketplace. Balance of trade numbers can run a trade deficit‚ showing that a country
