Nitrogen

Nitric oxide can be administered by a few different ways. When a patient is on a ventilator, nitric oxide is nebulized on the inspiratory cycle. Nitric oxide can also be given by a facemask or even a nasal cannula. The normal ranges for nitric oxide is 1 – 80 parts per million. High levels of nitric oxide can be very harmful and may even cause death, pulmonary edema or methemoglobinemia. A high concentration would be considered to be between 5,000 and 20,000 ppm. The length of time that…

A detailed description of soil locations, textures and physio-chemical properties can be found in Sections 2.3.1(page 41) and 3.3.1(page 56). We selected four types of soils out of seven types of soils, namely MGA, KBA, TAA and DUA. Key soil characterisation of these four soils is summarised in Table 4.2. The reason why these four types of soils were chosen for this chapter was that they had distinct soil parameters in terms of total organic carbon (TOC), Fe oxide, Al oxide, pH which have been…

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…

Pollinators, flowers, and their relationship play an essential role in ecosystems. Pollinators are responsible for facilitating fertilization in flowering plants, which provides seed production in fruits and vegetables. Pollination is important in agricultural communities with the fertilization of crops. It is estimated that pollinators contribute to the global economy by adding 217 billion dollars from pollinating a vast array of crops (Gallai et al., 2009). The pollinator-flower relationship…

Lemna is a free- floating aquatic plant from the duckweed family, that consists of small, individual thalli (Tkalec et.al, 2001). Lemna are small, fast growing plants and they develop dense mats on ponds, especially when enough light and nutrients are available (Gérard et.al, 2014). Salt is the most toxic substance, as it causes an inhibition of plant growth and a decrease in nutrient uptake (Chang et.al, 2012). Salt stress induces the production of abscisic acid (ABA), a plant stress hormone,…

We applied the thermodynamic model developed in this research to compare the equilibrium and experimental mole fraction of the product gases obtained from different bed materials. Figure 5 illustrates the evolution of the experimental mole fraction of the product gases for various bed materials. Also, a horizontal line indicates equilibrium mole fractions estimated by the thermodynamic model. It must be pointed out that the estimated equilibrium mole fractions of the product gases are expressed…

Bam! Bam! Bam! goes the gun of a soldier. Have you ever wondered where gunpowder came from? Gunpowder, as well as silk and paper, are just some of many objects traded along the Silk Road that have an impact on our lives today. To begin with the silk road was a trading system and gunpowder was one of the objects exchange on the silk road.Gunpowder is made out of charcoal but it is also known as black powder. Gunpowder is a explosive chemicals which means it is very dangerous. Back to what I was…

Explosion The explosion was a nice thing to learn if you want to be a bomb maker, I’m going to research the history about the bomb and explosion and then I’m going to research the step and the material about the bomb and how to make a bomb easy to carry and make the bomb not easy to be founded. If you want it to explosion, you have to have to material of that, so the material of that have a lot of kind such as: Octanitrocubane HMX Tetry Trinitrotoluene and the most famous one and the most…

Phosphorus Reduction: The New Pig in Town The 21st century is one abloom with scientific and technological advancement. From the sequencing of the human genome to the development of touchscreen phones, this century, albeit just beginning, has already surmounted the expectations of what people ever imagined possible. Advances in genetics have become especially important to swine production and, consequently, to the environment as well. Excess phosphorus in manure has the potential to runoff into…

Christian Friedrich Schonbein One of the more obscure scientists, Christian Friedrich Schonbein was well known for his discovery of ozone as well as work on fuel cells. He along with Friedrich Goppelsroeder discovered and coined capillary analysis, and later on, paper chromatography. My project centers on ink chromatography and capillary action, both of which were discovered by Friedrich Goppelsroeder and Christian Friedrich Schonbein. Of the two men, Christian Friedrich Schonbein was a more…
