With the expansion of our nation, so has the expansion of supply and demand for agricultural consumer goods, which led to technological advancements to mass produce and shipment. It was not noticed that this drive for agricultural needs would have a devastating impact on the environment…

Fig. 6 shows the results of air permeability, total water absorption, and voids. R mortars had lower permeability than the mortars with WTS. Air permeability of R was 1.13 x 10-13 m², a value 5 times higher than L60. The air permeability increased with increasing WTS content. The water absorption values ranged from 10.6% to 13.7%, and the voids from 9.6% to 12%. The results show that WTS replacement increased the porosity and permeability of geopolymer mortars. The geopolymer binders with WTS…

Background information on the area affected by the disaster: The diseases were first identified in the city of Minamata, Japan in 1956 which is Kumamoto Prefecture in the island of Kyushu and next it was at Niigata City, Niigata Prefecture, Japan. Minamata diseases are a neurological syndrome that results from pollution and environmental contamination. Types of ecosystems: Mercury contamination occurs through aquatic ecosystems in this case of Minamata Japan. Inorganic waste, like mercury,…

The Susquehanna River is home for many: animals, fish and people alike. It is also a key contributor to the Chesapeake Bay, being the largest tributary within the watershed. The pollution of the Susquehanna directly impacts the health of the bay. To understand the importance of the river to the bay, it is necessary to understand what is causing pollution and what solutions can be introduced to lessen the negative impacts. Pennsylvania is a large participant in rural farming as well as urban…

the author finds that the increase in globalization has led to the need for a global public sphere. However, the author discusses concerns with new forms of public spheres being mediated through advertisers. Thus, while one can deduce that the surface web and many forms of traditional media do not follow Habermas’ requirement of a public sphere being free from the economic markets (like advertising), the article will benefit my argument by showing that the Deep Web presents an unmediated…

surface area vs rate of time Introduction: In the investigation an experiment is conducted investigate if the breaking of alka seltzer into ½, ¼ and none effect the time it dissolves. The context of the problem is the time it dissolves to have the medicine show its effect. This problem exist in real life as people take alka seltzer to relief heartburn, acid digestion and stomach aches. This experiment would benefit society because it informs the society the better way of consuming medicine or…

How To Prevent Algae And Moss Damage From Happening To A Cedar Roof One thing that can cause damage to a cedar roof is algae and moss growth. It will eventually cause rooting and cracking, as well as the potential failure of your cedar roofing. In order to get the longest lifespan possible from your cedar roof, you’ll need to follow some tips to prevent the algae and moss growth from occurring. Get An Annual Roof Inspection If you do not work with roof every single day, you may not be aware of…

water fantastic troubles every 12 months. due to manure management troubles (EPA, 2001). This contamination may be because of surface discharges or different kinds of discharges. surface discharges may be due to heavy storms or floods that purpose garage lagoons to overfill, walking off into nearby our bodies of water. Contaminants can also portable over land or through surface drainage systems to close by our bodies of water, be discharged thru artificial ditches or flushing structures locate…

Introduction The starch factory stream is located in Proctor Park in Utica, NY. This stream eventually flows into the Mohawk River. It is located on the Mohawk River watershed. The Mohawk River Watershed contains “4,086 miles of fresh water rivers and streams.” (McGivern 1). A water shed is the section of land in which run off “drains” into a “common outlet” (Lattuca 123 and Raven et.al. 66). The Environmental lab students conducted this study to answer few questions like: is the water less…
