equation (Fig. 2(a), 2(b) and 2(c)), the initial rate of adsorption (h, mg g-1min-1) was obtained (Table 1). The highest initial sorption rate (0.462 mg g-1min-1) was obtained from nickel sorption at 5% adsorbent dosage and initial pH 5.0. By increasing biomass dosage (from 3 to 5%), the metal removal tended to increase. These results are in agreement with the finding of Galedar and Younesi (2013). For the effect of initial pH, Sujatha et al. (2013) explained that at higher pH (>4.5), the…

Ocean acidification can be defined as the change in ocean chemistry driven by the oceanic uptake of chemical inputs to the atmosphere, including carbon, nitrogen, and sulfur compounds (Guinotte and Fabry, p.320). Today, the overwhelming cause of ocean acidification is anthropogenic atmospheric carbon dioxide. Over the past two-hundred years, the rapid increase in anthropogenic atmospheric carbon dioxide has directly led to decreasing ocean pH through air-sea gas exchange, driven by the land-use…

Though Biomass is a renewable fuel its use can still contribute to global warming. • Hydropower plants installed to generate electricity also create problems like human displacements and are damaging the ecosystem. Environment concerns about the effects of reservoirs…

Snails dominated the dry biomass of free-living organisms with a percentage of 60% across streams. In addition, Alabama streams have more snails than any place in North America. However, for a long time, there is being an issue on determining the variables that lead them to their…

The Pacific Ocean Paradise documents the reefs of five islands named Flint, Vostok, Starbuck, Malden, and Millennium Atoll. With a small group of people that go on a mission to raise awareness and show “ ocean lovers” what is going on at these reefs of the islands. The leader of the group is Dr. Enric Sala who is a research scientist and Natural Geographic Explorer. He sees Tahiti as an almost impossible goal to preserve and is looking for untouched places where no humans have been. They say it…

Lionfish Invasive Introduction Non-native species have be released and introduced all over the world, but nothing quite compares to the invasion of the Lionfish. Species invasions, such as the Lionfish, can serve as a major threat to native ecosystems by causing ecological damage (Côté, 2013). Finding out what these ecological damages might be and how to slow down the process is Pterois volitans & Pterois miles The fish commonly known as the Lionfish has two species, Pterois volians and…

ae/ha (Collier et al. 2007). The Montana trial herbicides were applied July 8, 2006 and for the Wyoming trials July 10, 2005 and July 15, 2006. After a 90 day, period the Canada thistle was then destructed for the drying and measurement of height, biomass and root…

oil each year to fill its ever growing need for fuel. The United States needs to use new alternative energy sources to to prevent the spending of millions more on foreign oil. Renewable sources such as wind, solar, geothermal, hydroelectric, and biomass provide alternative energy sources. Implementing alternative energy sources will decrease the dependency on oil which will save the country millions of dollars, while also creating many jobs. The U.S.’s dependence…

backwash still remain as the major drawbacks during long-term filtration. Therefore, more study is required to understand fouling phenomenon of nonwovens. As a conclusion, nonwovens cannot yet replace microfiltration membranes in bioreactors for biomass separation; further studies are inevitable to produce low-fouling…
