the hurricanes in Atlantic Ocean and floods in this decades. This has resulted in warmer climate that lead to storms. The floods and storms has always made destruction to the lives and materials. The infectious diseases, injuries, contamination of water that ultimately affected the health care. The allergies and respiratory diseases caused to the pollutants in air. Most of the Americans is living in the climate where the standards has exceeded for health. The atmospheric smog has increased the…

sol–gel method using tetra-n-butyl titanate as the precursor. Solution A was prepared by dissolving 17 mL TBT in 30 mL anhydrous ethanol with stirring (300 rpm) for 30 min. The other solution that contained 28.35 mL anhydrous ethanol, 7.25 mL deionized water and 20 mL 3 M acetic acid was slowly added into the above solution with magnetic stirring at room temperature. The prepared mixture was further hydrolyzed for 60 min with stirring until the transparent sol was obtained, which was aged for 20…

Introduction Lead (Pb) contamination is a pervasive issue in many low-income neighborhoods throughout the United States. The toxicity of lead poses significant risks to human health, and proves to be especially harmful for children in terms of cognitive and physical development. Lead in the environment is primarily related to a legacy of anthropogenic sources including leaded gasoline, leaded paint, and various industrial applications. Although the presence of heavy metals is ubiquitous in the…

2. The important smart strategies to deal with the current problems facing agrobiodiversity, CC and food security. (question 3 of Chapter 3) Subsequently, agricultural expansion has contributed to widespread land degradation and climatic changes through the emission of greenhouse gases (GHGs) from sources, such as soils, biomass burning, enteric fermentation, rice cultivation, fertilisers and manure management. Climate change and land degradation are intricately linked because of the feedback…

What does specific heat 4 200 J of heat needs to be supplied to 1 of water 4 200 J kg-1°C-1 kg of water to produce a 1 °C temperature mean? increase. 6. The physical When two objects of equal mass are heated at meaning of equal rates, the object with the smaller specific specific heat heat capacity will have a faster…

Fat was dissolved in 25 mL of the solvent (a mixture of chloroform and acetic acid). Then, 1 mL of saturated solution of potassium iodine was added, and kept in a dark environment for 10 minutes. After this time, 20 mL of distilled water and 1mL of starch solution (1.5%) were added. The sample was titrated by 0.01 N Na2S2O3, until disappearance of the blue color. The amount of peroxide was calculated, using the following equation (Harold, Kirk, and Swayer 1981). PV = (1000 (푉1-푉2)…

ammonium in its tissues. There are two groups of squid in relation to density in water; the first are denser than water and must swim to stay afloat, the second are “nearly neutrally buoyant” (Clarke et al. 1979). The giant squid falls into the second category; it remains buoyant because of ammonium chloride filled pockets in its muscles, which balance its density. This means that it does not need to be active to stay in the water column, freeing it to lie in wait for food to happen by. Recent…

ARCHITECTURE: Most houses were made of block. The banks of the Nile gave the mud used to make blocks. Block creators gathered mud, added straw and water to it as required, and stepped it with their feet until it achieved the correct consistency. The blend was then put in a shape. Once formed, the blocks were expelled from the shape and left on the ground to dry in the sun. Egyptian workers would have lived in basic mud-block homes containing just a couple household items: beds, stools, boxes…

facility the oysters are further cared for and developed, getting ready for shipping and transporting to various markets. This oyster farm makes use of recirculation systems, which uses plenty of energy in order to pump water through its system. So the use of energy is more than the water use, due to the recirculation…
