Drainage

diagram for inorganic compounds which are likely to exist under different pH and Oxidation states. Overall, Aresenite is generally found under reducing conditions especially within areas suffering from a high pH such as land contaminated by acid mine drainage. Whereas arsenate is typically the more dominant under oxidizing conditions, and therefore is likely to occur within the upper well ventilated zones of soil. Additionally, in the presence of microorganisms the formation of organic arsenic…

Today, olive oil is widely used for a variety of purposes such as cooking, beauty products, and medicine, leading to a world consumption of about 535 million gallons per year on average. Evidence shows that olive oil was being produced during 4500 B.C. in modern day Israel. What is olive oil? Olive oil is the oil acquired from olives. This fat is obtained by pressing olives, but the process is not as simple. Olive trees need numerous years and extra care to be ready and to produce an optimized…

Research objective 3: Evaluating the coastal vulnerability to sea level rise and hurricane for the coupled human and nature system under consistent or even increasing urban growth process. Question 3.1: How to define the vulnerability in the coupled human and nature system? Based on the vulnerability conceptual framework in Turner (2007), three general components, namely exposure, sensitivity and resilience are considered. With the first two components considered separately for nature and human…

When scientists entered the Galapagos Rift they found a variation in temperature that changed drastically. The data collected by researchers revealed temperatures fluctuating between 320F to 7500F, within a relatively short distance (NOAA). Not only high temperatures were registered, but a complete ecosystem was surrounded by a unique marine life capable of surviving the extreme conditions. Since then, not just the ocean floor has been part of the scientist 's investigation; but the marine…

Statement of Problem The Ely Copper Mine was declared a superfund site in 2001. Mining activity occurred from 1821 to 1920 Ore body discovered in 1813 Location The Ely Copper Mine is located in East Central Vermont in the rural town of Vershire, Orange County. The site is part of a region referred to as the Vermont Copper Belt, or the Orange Country copper district. Over 30 miles long, the belt runs in a NNE–SSW direction. The Ely Mine is one of three major mine sites in the region. It…

Caspian Sea, Black Sea, and Azov Sea ("Zebra and quagga mussels | GLEAM," n.d.). The first appearance of Quagga mussels was in Lake Erie in 1989 ("Zebra and quagga mussels | GLEAM," n.d.). The native habitat of Quagga mussels is the Dneiper River drainage of Ukraine. In the Great Lakes Quagga mussels are a dominant invasive species ("Zebra and quagga mussels | GLEAM," n.d.). Profound impacts are experienced in the Great Lakes ecosystem due to the colonization of zebra and quagga mussels ("Zebra…

Asphalt milling is often performed to eliminate low spots, smooth the transition between pavements, level rutted pavement or eliminate bumps in the pavement. It is common to perform milling prior to installing an asphalt overlay to help resolve drainage issues or refine the pavement's…

Fluctuations of temperature and moisture are common in Iowa during December and January. These variations from rain, freezing rain to snow events, occur throughout the early winter months. Because of these transitory thaws and freezes, turf potentially develops an ice layer over the top of the turf canopy. The thickness and type of ice is dependent on the weather and site specific conditions. When thick dense ice coats the surface it can create hypoxic conditions (lack of oxygen) in combination…

There is a saying that “All roads lead to Rome.” Well, at one time this was true. Rome was one of the first civilizations to pave its roads. These roads were first built around 312 B.C.E. and some roads remained until the 1900s. Many of the roads were built by soldiers, who were the first ones to actually use the paved roads. Because the roads were paved, the citizens thought that Rome would last forever, so the empire had to build and have strong roads that wouldn’t have to be repaired often,…

When rolling out industrial or mining operations, one equipment that we should never overlook is a prime generator. These large machines are indeed very essential in applications in remote areas or in situations where there is no backup power as they serve as your primary electricity source. In other words, there are something that you can rely on. They are even the ideal choice if you're searching for units that can provide that "unlimited run time". Now in case you're in the hunt for a prime…
