Report on "Formation of Nitric Oxide in Premixed Hydrocarbon Flames" by C. P. Fenimore, Proceedings of the Combustion Institute, Vol. 13, p. 373, 1971. (You can't review this one since I've already given you the "answer" below.) At the time this paper was written, the formation of nitric oxide in premixed hydrocarbon flames had not been completely characterized. Concentrations of NO resulting from simple N2O2-NO combinations could be calculated but it was still uncertain how fuel-rich flames could produce such high levels of nitric oxide . Fenimore set out to test the known laws of NO formation in relation to hydrocarbon flames in an attempt to find a more accurate explanation for how an ...

    HW Paper

    Drexel, MEM 444

    Excerpt: ... compression stocking, as mentioned in the article, are seemingly excellent ways to keep blood flowing. In my mind, a dialysis machine hooked up to the legs would be another way to go, but this brings infections and even more complications into the picture. As learned in class, Nitric Oxide (NO) is released into the body to reduce the value of the wall shear stress and to dilate the vessel. If the wall shear stress is too large, NO can be introduced into the surgery process to decrease the wall shear stress. Another idea is to increase the level of oxygen in the blood. "After a major surgery, hematocrit often drops from 45 to 30%" (MEM 444 Lecture Notes), and this can lower the oxygen-carrying capacity of the blood. Giving the patient oxygen could be another potential suggestion. The increase of blood clots after surgery (from 9/1000 in 1996 to 14/1000 in 2006) is not something to be taken lightly. The fact that these hospitals are participating in the "Partnership for Patient Care" means that the hospitals ...

He tells you that the dentist is going to give him nitric oxide as an anesthetic. Alarmed, you tell him that he must be sure not to take Viagra before the appointment. What are you concerned about? Provide a complete molecular explanation (a drawing plus a couple of sentences is one way to answer this). You father actually confused nitrous oxide (laughing gas) with nitric oxide the signaling molecule, but you are right to be alarmed based on what he told you. Nitric oxide , if it were to get to the smooth muscle cells in the penis, will cause those cells to produce cGMP by activating a guanyl cyclase (+5). The cGMP will cause the smooth muscl ...

    Literary review

    Emory, BIO 142

    Excerpt: ... Musi Nde February 10, 2008 Literary Review Bioligy 142 9A The question posed for this particular research project is what the effects of Nitric Oxide (NO) are on bacteria that are collected the waterways of the Mt. Arabia outcrops. Based on research, it is proposed that the addition of nitric oxide to the bacteria samples will facilitate the growth of the bacteria and increase the rate at which the bacteria multiplies and increase the colony sizes. In the article" Effects of nitric oxide and nitrogen dioxide on bacterial growth" The effects of NO are not bactericidal, but rather are bacteriostatic. This means that at the concentrations that were tested, it was shown that nitric oxide halted the reproduction of the bacteria. rather than kill the bacteria. The reproduction of the bacteria became static, no deaths and no reproductions. It was shown however that bacterial survival rates increased when the initial concentrations of nitric oxide were increased past 1.0 ppm. The second article, , bacteria that is ...
