Nitric oxide

oxygen when there is there is dilation of blood vessels, which decreases blood pressure. This is also known as vasodilation. Thus, the blood vessels relax and widens enabling greater blood flow or the tissue allows greater perfusion by the use of nitric oxide. Hypoxemia which is also known as low oxygen level can affect the brain, liver, and other organs can…

My aim is to determine the different effects that various pH levels have on the growth of cyanobacteria, by testing various concentrations of nitric acid in different samples of cyanobacteria of equal masses. My hypothesis is that acid rain will greatly affect the growth of cyanobacteria. The higher the acidity level of the water, the less the cyanobacteria will grow. I chose this topic because due to human activities, many different chemicals have been released into the air and they changed…

The patient was admitted into a small, rural hospital at 1900 for an ongoing complaint of unrelieved indigestion. The patient, 48 year old male has a history of and is presently involved with smoking. After admission into the hospital it is ruled out that the patient underwent a rule out myocardial infarction with further testing involving a cardiac catheterization to be done after admission upon a separate medical center. The patient also presents to the hospital with a history of a high-fat…

Introduction Acid rain is a rain that contains a high concentration of pollutants, chiefly sulfur dioxide and nitrogen oxide, released into the atmosphere by the burning of fossil fuels such as coal or oil .It can have harmful effects on plants, aquatic animals and infrastructure, when the sulfur dioxide and nitrogen oxide, react with the water . The chemicals in acid rain can cause paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues.…

Anthony Alvarado Bio 1A Chronic oxidative stress via hydroxyl radical and imbalanced redox homeostasis Redox hemostasis has been shown to be an important factor in the overall aging and neurodegeneration processes in mammalian models; such as, Alzheimer’s and Parkinson’s. As a result, redox homeostasis has been a key point of interest in current research. Redox homeostasis is the balance between electrophiles and nucleophiles in a system, more importantly in a biological system. These…

treatments were applied to clean heavily n-doped Si substrates acting as the gate electrodes for transistors and as the input electrodes for inverters. Approximately 10 nm-thick HfOx films were prepared by spin coating with a HfCl4 precursor solution (nitric acid added to HfCl4 dissolved in absolute ethanol) on the substrates at 5,000 rpm for 30 s and then annealed at 500 °C for 1 h. For the COC passivation the HfOx surface was spin coated with 0.5 wt% COC in toluene with an average thickness…

Climate change is an extraordinarily important problem, and requires immediate and radical government intervention on the sources of greenhouse gas emissions. Climate change’s effects are already being felt around the globe in the form of coral bleaching, erratic and extreme precipitation and weather patterns, rising sea levels, arctic ice melt, and unprecedented record temperatures. If mitigation efforts are not implemented, it will impose epoch-making impacts geographically, environmentally,…

when it falls through the atmosphere and forms carbonic acid (H_2 CO_3), lowering the pH of rain to around 5.6. However, the release of nitrogen and sulfur from burning hydrocarbon fuels can lower the pH of rain to as low as 2.  Nitrogen and sulfur oxide are common in the air around industrial areas and has serious negative effects of aquatic environments. Acid rain forms because petroleum naturally has impurities in it. This is because when the plant or animal died millions of years ago the…

Burning fossil fuels release nitric oxide which combine with other elements to form acid rain and also smog. Fertilizers put my nitrogen into the soil, which in the end add more nitrogen to the cycle. Lastly, deforestation is an issue because the nitrates in the soil can’t be absorbed…
