Alkaline soil is referred to by some gardeners as”sweet soil”. The pH level of alkaline soil is above 7‚ and it usually contains a great deal of sodium‚calcium and magnesium. (1) Alkaline soil occurs in areas with high limestone content‚ easy souble phosphorus and calcium binding‚ formation of insouble calcium salts of phosphorus‚ reducing the effectiveness of phosphorus. Also‚ in calcareous soils‚ boron‚ manganese‚ molydenum‚ zinc‚ iron greatly reduces the effectiveness of the crop often feel inadequate

One of the types of rocks that can be found on the Earth are sedimentary rocks. There are two other kinds which are igneous and metamorphic rock. Sedimentary rocks cover about 75 to 85 % of the land on Earth. When pieces of rock or parts of once- living organisms or minerals from precipitation deposit and solidify on Earth’s surface they for sedimentary rocks. (Murck‚ et al.‚ 2008) In addition‚ the way the plate tectonics move‚ can significantly affect sedimentation and the formation of sedimentary

Africa is the world’s second-largest and second-most populous continent. In measure of wealth it is one of the wealthiest continents in terms as natural resources. Although Africa’s abundant amount of natural resources‚ it remains the world’s poorest and most underdeveloped continent. This could be a result of many things such as corruption within the government‚ failure in central planning‚ and lack of access to foreign capital. Sub-Saharan Africa is the least successful region in the world in reducing

procedures are usually very accurate‚ but more tedious than other methods. The only major equipment needed for gravimetric analysis is an accurate balance. Sulfur can be determined gravimetrically. Sulfur is found in minerals such as iron pyrite‚ gypsum and coal. Coal may contain as much as 4% sulfur in various forms: pyritic sulfur (as S 2 2-)‚ sulfur in sulfates (as SO42-) and in a variety of organic forms‚ such as thiophenols and thiophenes. When coal with high sulfur content is burned sulfur

their structure forming a complex in which water generally bonds with the cation in ionic substances. The water present in the latter case is called water of hydration or water of crystallization. Common examples of minerals that exist as hydrates are gypsum (CaSO4•2H2O)‚ Borax (Na3B4O7•10H2O) and Epsom salts (MgSO4•7H2O). Hydrates generally contain water in stoichiometric amounts; hydrates’ formulae are represented using the formula of the anhydrous (non-water) component of the complex followed by a

Formal Analysis: The Cylinder seal and The Ashurbanipal hunting lions The purpose of this paper is to examine the differences and similarities between early Akkadian and Assyrian art forms by comparing two figural sculptures‚ the Cylinder Seal (Ca. 2254 – 2193 BCE) and the Ashurbanipal hunting scene (Ca. 645 – 640 BCE). Due to cultural and periodical differences‚ it is unavoidable to find varying mastery of techniques‚ negotiated objects or subjects being depicted in the sculptures. These
