Thermohaline circulation

In the academic library that I chose to examine, finding the reference desk is no easy task for the unfamiliar patron. With three major entrances and six floors to navigate, this library is an epitome of what most libraries would strive to have: boundless space for patrons and a vast, growing collection. The patron, however, could easily take one glance at this gargantuan building and easily become overwhelmed, despite the services that this one building contains, such as being combined with…

Cardiovascular disease has long been the leading cause of death in the United States, and predicted to affect forty percent of our population by 2030 (Narang et al., 2016). Furthermore, research indicates that the cardiovascular workforce is inadequate to meet the rising demands of this patient population (Narang et al., 2016). In particular, a subset of cardiac care nurses, cardiac catheterization laboratory nurses are key members of this cardiovascular workforce. Although this nursing…

Discovering a new world below the ocean intrigues me. I have never been one for loving ocean creatures, but I do enjoy learning about the world below us. I found several facts interesting as I read the articles including: how osmosis and salinity functions, how seawater cells move, how pH affects the ocean, how decomposition works in the environment, how upwelling stirs up nutrients, and how water temperature affects organisms. One of the interesting facts discusses why osmosis and salinity…

One of the main abiotic factors influencing the distribution of biomes is global atmospheric circulation. Global atmospheric circulation is the mass movement of air around earth caused by thermal energy. This mass movement of air causes three distinct atmospheric circulation cells to form, these are the Hadley Cell, Ferrel Cell and Polar Cell. Between these three cells is a dynamic area called the Intertropical Convergence Zone. Persson (2006) tells us that the Hadley Cell is caused by solar…

In the script Ms. Young complained that at first, she experienced moderate chest pains that progressively got worse before her heart attack. This pain was described as if someone was putting pressure on her chest and it radiated down to her arms. Additionally, she felt as if she was struggling to breathe, nauseated, weak and sweating. This fits with the diagnosis of coronary artery disease that is the source of developing chronic stable angina and can induce a myocardial infraction like she…

Chapter 4 STENT DESIGNS Stents are small meshed spring like tubular structures used in angiolplasty to treat the narrow or weak coronary arteries that carry blood. The implantation of stent prevents the arteries from blowing out for a longer duration after surgery. One of the causes for blockage of arteries is the plaque deposition in the inner parts that eventually block the blood flow and may also lead to heart attacks.…

Atmospheric Global Circulation is the movement of air caused by solar energy and the interaction of warm and cold air - this convergence forms cells or belts over the Earth’s surface. George Hadley (1685–1768) a British physicist and meteorologist, who first described this theory in 1753, did so using what is known as the Single-Cell Atmospheric Global Circulation Model or Hadley Cell (The Editors of Encyclopædia Britannica, 2007). Hadley’s Single-Cell theory failed to consider the Coriolis…

During ten thousand B.C. at the Northern Hemisphere, an abrupt global climate change that led to glacial like weather occured. This period is known as Younger Dryas Climate Event. Due to the earth warming, the ice age starting melting. This huge amount of freshwater started flowing into the gulf through the Mississippi River and also to north Atlantic from the east coast. This unusual flow of freshwater into the saltwater caused the water currents to change suddenly causing different weather…

supposed by some are probably in part the effect of this current. (J. H. Tuckey, 1815) Ocean currents are water movement and circulation forms that effect climate zones and weather patterns around the world. The directions these currents take can be affected by climate, actions of celestial bodies…

deep water formation that alter the thermohaline circulation of the global ocean by the rapid increase in temperatures. Finally, scientists reveal a three-part mechanism whereby the variation in total solar irradiance (TSI) affects Arctic temperatures by modulating the thermohaline circulation (THC), the InterTropical Convergence Zone (ITCZ) rainbelt and tropical Atlantic ocean conditions, and the intensity of the wind-driven subtropical and subpolar gyre circulation, the ring-like system of…
