Marburg is an infectious virus that hinders the lives of many people, often occurring in the most rural regions of Africa (35). The Hot Zone by Richard Preston and “Stalking a Killer” by David Quammen both explain Marburg’s severity, among the other filoviruses, and the proper precautions that occurs when handling this agent. “Stalking a Killer” is an article that touches on Marburg and the different types of Ebola; it tells short accounts of infected victims. The Hot Zone is a study about the…

I also prefer the term "melting", though I recognise that this term is potentially confusing for a lay or beginners' audience. The analogy with melting of water ice, while intuitive, may invite the misconception that DNA "dissolves" into very small molecules rather than separates into its two strands. The lede states "These thermal cycling steps are necessary to physically separate the strands (at high temperatures) in a DNA double helix (DNA melting)", and in the description of the PCR steps it…

Some of these particles are from the sun’s atmosphere and are charged. From the different gas particles, different color variations are created. Thus from the northern lights , we get combinations such as blue green purple, green purple pink and black green hair colors. After applying the colors, you may leave…

How Does Temperature (thermal kinetic energy) Affect the Phases of Matter? Observation Can matter be in anything that elements can mix to something different? Why does matter have to have more than 2 elements? What things do not have matter? Why does matter have to have more of, weight, volume or density? Why is there such things called matter? Why is the earth made of matter? How much does matter influence the earth and what it does to help? What is matter? How does…

Livestock production and climate change affect and get influenced by each other. The most important effects of climate change on the environment and livestock include rise in temperature, elevation in sea level, alteration in microbial eco-system and several others effects, known or unknown which might affect the livestock positively or negatively. There have been various predictions about the quantum of sea level rise with varying degree of confidence because many of the natural phenomena have…

classified as: high-density lipoproteins (HDL), low-density lipoproteins (LDL), intermediate-density lipoproteins (IDL), very low-density lipoproteins (VLDL) and ultra low-density lipoproteins or chylomicrons (ULDL). [10] Low-density lipoprotein particles, which are more specifically the objects of…

minimal intervention. Air abrasion is a treatment modality, which preserves the structural integrity of the sound tooth structure remaining around a carious lesion. Hydro air abrasión propels a stream of aluminum oxide particles generated from compressed air with water. The abrasive particles strike the tooth at high speeds and removes carious tooth structure preferentially. Clinically, air abrasion offers numerous benefits; it is kind to pulp and reduces enamel without the inherent micro…

the chemical in grams” ("Propulsion." What Is a Mole?). “The amount of a pure substance is expressed by the SI base unit of the mole”. One mole of a substance contains 6.02 x10^23 particles of the substance. That number is known as Avogadro’s number ("Amount of." SI Units Explained). “The number of atoms or other particles in a mole is the same for all substances” (The Editors of Encyclopædia Britannica). That…

radionuclides in plants depend on their precipitation and adsorption with soil particles while concentration of radionuclides in soil decreases by a leaching process. Additionally,…

Breathe The Air. “ The outdoors was once a simple prescription for good health. No longer.” Summer time, we all can’t wait until its here, but then it arrives and the heat arrives with it. During the summer month’s people are most exposed to particles in the air causing bad air making it hard to breathe. “Chemical processes…
