SALINITY AND DEEP OCEAN CURRENTS OVERVIEW Ocean currents arise in many different ways. For example‚ wind pushes the water along the surface to form wind-driven currents. Deep ocean currents are caused by differences in water temperature and salinity. In this experiment‚ the students will hypothesize the cause of ocean currents and then develop a model to explain the role of salinity and density in deep ocean currents. CONCEPTS Salt water is more dense than fresh water‚ and is therefore

Deep venous thrombosis Deep venous thrombosis is a blood clot that forms in a vein deep inside a part of the body. It mainly affects the large veins in the lower leg and thigh. Causes When a clot breaks off and moves through the bloodstream‚ this is called an embolism. An embolism can get stuck in the brain‚ lungs‚ heart‚ or other area‚ leading to severe damage. Blood clots may form when something slows or changes the flow of blood in the veins. Risk factors include: • A pacemaker catheter that

In response to this article I would have to say that it is quite an unprepared protestor unknowing of his own stupidity. He calls out the scientists fighting the overgrowth of this knotweed saying this and that‚ with reasonable arguments in my opinion‚ but then concludes with an overwhelmingly lacking solution of his own. John Stahl states‚ "I’m not sure how good knotweed will be as a paper source but it doesn’t matter." Let’s review John’s solution . John’s solution was to use knotweed as a paper

INTRODUCTION BP originated from a British petroleum company founded in 1909. After experiencing crises during the 1980s-1990s‚ the company started to have a cost cutting culture. During mid-1990s‚ with an aggressive growth strategy‚ BP started to grow and reposition. After BP merged with Amoco in 1998‚ John Browne started to serve as chief executive until May 2007.

I dive and twirl‚ gazing up at the surface and see beams of sunlight penetrating the speckled density‚ shining sparkling rays down into the abyss. The deep green kelp sways with the rhythm of the tides‚ dancing back and forth. The water is cool‚ enlivening. When I dive deeper‚ through spiraling threads of light‚ I enter a bright kind of darkness. Here there is a silence that consumes me. Although
