Islands in the eastern Pacific. Scientists exploring the area along the mid-oceanic ridge had noticed drastic temperature changes in their data. With the help of ALVIN, a research deep sea submersible, they discovered vents that were pouring out hot fluids from beneath the ocean floor (Hydrothermal Vents). Hydrothermal vents are fissures in the earth’s surface from which geothermally heated water rises. They are normally found near volcanically active areas, usually in clusters above the given…

otherwise known as fracking. The concept of fracking is quite simple. Rocks such as shale which are about 2.000 feet underneath us contain natural gasse. To get to them, a horizontal well-like construction is built to reach down to the rocks and a fluid is pumped down, causing the…

What is HIV? Human immunodeficiency virus (HIV) is a Lentivirus from the family Retroviridiae[1] ,which infects CD4+ T cells, dendritic cells and macrophages[2]. This results in a loss in immune function and eventually acquired immune deficiency syndrome (AIDS) when CD4+ cell count is very low[3]. There were approximately 1.5 million deaths in 2013 as a result of HIV-related causes[4] , many of these deaths occur due to the immune system being too weak to defend itself against opportunistic…

that the different bodies stay within a couple hours drive of each other. A’s looks, body, situation, and gender change every day. Since A doesn’t feel any stability with one gender or the other they cannot be assigned to one gender; they’re gender fluid. A isn't a boy or a girl. For example when A says “I had yet to learn that when it came to gender, I was both and neither” (David levithan, 254). This quote…

of his diagnosis of congestive heart failure and his age. The oedema is caused by an accumulation of fluid build up that is causing swelling in Williams’s lower legs and has become perfused by his peripheral vascular system. The excess total body water in the patient measures peripheral oedema; it is best treated by eliminating the excess fluid, with medicating or mechanically removing the fluid (Clarke, Cleland…

Associated problem one Due to Beryl not being very mobile, having a poor diet and being incontinent she is at risk of developing pressure ulcers. A pressure ulcer is the localised injury to the skin or underlying tissue usually over a bony prominence as a result of pressure (Delves-Yates, Everett & Wright, 2015). All patients regardless of age are potentially at risk of pressure ulcers (Myers, 2014). There are around 410,000 people who develop pressure ulcers a year which costs the NHS £1.8-£2.6…

amounts of toxic fluid, loaded with silica sand and chemicals, are pumped into the ground. This fluid is not always pumped back out of the ground and seeps into surrounding groundwater. North America should stop the use of fracking because it can cause earthquakes, puts the public at risk, lowers the quality of life for people near fracking grounds, and pollutes the environment. In Western Canada there have been many earthquakes directly related to fracking. When the fracking fluid and sand are…

concentration of S0 (g/g leaf particles) to form a packed bed system. Fresh supercritical solvent is fed in to the bed, the pore and void volumes () are initially free of solute, and the process is isothermal. The total mass balance in the supercritical fluid phase of this system can be described by the following expression: α ∂C/∂t+u ∂C/∂z-α(D_z (∂^2 C)/(∂z^2 )+D_r (∂^2 C)/(∂r^2 ))=-(1-α) ∂S/∂t (1) In spite of extraction vessel dimension with length to diameter ratio…

How does one even extract natural gas and oils? Once the injection process is completed, the initial pressure of the rock formation that they injected the solution into causes fluid to return to the surface via the wellbore. This fluid may contain the injected chemicals plus naturally occurring materials. These naturally occurring materials can be anything from brines and metals to radionuclides and hydrocarbons. The flowback and produced water is typically…

According to TheJoint.com, your body stops directly supplying blood to the intervertebral discs by the age of six. After that, you’re on your own! By keeping your spine moving, you promote the passage of fluids into you discs, thereby promoting a healthier, pain-free back. Back doctor Plano: Stretching and dynamic movements Here are three additional keys to a healthy back: dynamic motions, stretching, and strengthening exercises. Experts recommend performing…
