Differential Equations Johann Bernoulli
2,228 words... see the general scheme of the works with them, and they developed his ideas, calculating tables, and sometimes compiled examples. For example Euler credits Albrecht, Krafft and Lexell for their help with his 775 page work on the motion of the moon, published in 1772. Fuss helped Euler prepare over 250 articles for publication over a period on about seven years in which he acted as Euler's assistant, including an important work on insurance which was published in 1776.

Td Tr Tr Td Erectile Dysfunction
1,318 words... The physiologic mechanism of erection of the penis involves release of nitric oxide (NO) in the corpus cavernous during sexual stimulation. NO then activates the enzyme guanylate cyclase, which results in increased levels of cyclic guanosine monophosphate (cGMP), producing smooth muscle relaxation in the corpus cavernous and allowing inflow of blood. Sildenafil has no direct relaxant effect on isolated human corpus cavernous, but enhances the effect of nitric oxide (NO) by inhibiting phospho...

858 wordsAlthough Bryophytes and Pterophytes are both plant divisions with a common ancestor, they have little in common. While Bryophytes (mosses) are generally nonvascular and very short in height, Pterophytes (ferns) are vascular plants that usually grow much taller than mosses. While the dominant generation in mosses is the gametophyte, ferns exhibit the sporophyte generation. The details of their alternations of generation vary as well, although both have diploid and haploid stages. Alteration of ge...

Gas Chromatography Data Collection
939 wordsGas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to be a ...
