Aim The objective of the experiment is to explore the process of simple analysis techniques and representative sampling in determining soil nutrient levels. Soil samples collected from Flinders Campus were used to determine their pH, salinity, ammonium, nitrate, phosphate, and nitrite levels. Introduction Unless there is a specific problem detected, the most common reason for undertaking soil analysis is to detect the levels of essential nutrients (Guo, 2009). The commonly analysed nutrients in…

period was the last period of the Mesozoic Era, right after Jurassic period and followed by the Paleogene period of the Cenozoic Era (International Commission Chart, 2014). 'Creta' in Latin means chalk and this is due to the large amount of calcium carbonate deposited by shells of marine animals thus resulting in large quantities of chalk (American Geological Institute, 1972). The shifting of continents as the result of the separation of the world-continent Pangaea continued on in the…

Scientists have discovered that during life on Earth there has been 5 mass extinctions. These mass extinctions are said to be a normal part  of life and might even be an important factor for life on Earth. The main mass extinctions that have been discovered are the Ordovician Mass Extinction, the Devonian, Permian, Triassic, and the Cretaceous Mass Extinction. Scientists now even believe that we are not only part of the problem but the main subjects of the sixth mass extinction caused by…

Discuss fitness tests or methods of evaluation that should be used to assess the client, providing rationale for your recommendations.

2.2.2. a) USING KAOLIN BY-PRODUCT The synthesis process (D. Brahmia 2014) was carried out in two steps namely, (1)Metasilicate sol preparation and (2) Metasilicate destabilization with acid. In the first step, a mixture of sodium carbonate and sand were heated to 1000°C to form silicate. Sodium silicate formed in this study was prepared with different molar ratios, n, ranging from 1 to 4 as shown in Equation (2.1). The result obtained was generally in the ratio of three SiO2…
