What my project is about: I will be comparing results from water testing I did at two different water bodies to prove that the catchment area has an influence over the water quality in the different water bodies. The first water body I tested was the small dam in the bokkie park situated in between residential areas and in the middle of a piece of land solely used for animals. The second water body I tested was the small dam across the road from the Trinity Church in Boksburg on Rondebult Road‚ which

Feasibility trails were carried out by melt granulation method. Method: Drug was passed from 40# sieve. Weigh accurately drug‚ polymer and other excipients. Wax was melted at 60-65°C. After that drug and other ingredient were added to wax and mixing of drug and wax was done. Prepared lump was passed from 10# sieve. Granules were dried at 40°C. Lubricant was added to granules. Granules were compressed to prepare tablets. Table 4.6: composition of trail F1 and F2 Ingredients F1 F2 Metformin Hydrochloride

TITLE: Water Based Drilling Fluid Analysis EXECUTIVE SUMMARY: Analysis of drilling fluids is essential to their performance. In this laboratory exercise the aim is to test three drilling fluid samples for; density and rheological properties‚ Fluid loss‚ chemical analysis i.e. testing pH‚ alkalinity‚ testing for chloride ions‚ calcium carbonate‚ calcium‚ bentonite; also determining the amount of solids present in the samples as well as volumes of oil‚ water and solids contained in the sample‚ and

and sensuous beauty is the Onyx gemstone. The semiprecious stone‚ Onyx‚ is a chalcedony quartz. It is mined today in Brazil‚ Afghanistan‚ India‚ North America‚ and Uruguay. Onyx has a fine texture‚ wax-like luster‚ and a hardness between 6 and 7 on the Mohs scale of mineral hardness. It features various bands of color‚ but black is the most popular. Common onyx

Class 1 Metallic bonding: Found in metals and alloys‚ 1‚ 2‚ or 3 valence electrons that are not bound to any particular atom in the solid. They drift throughout the entire metal. This results in a sea of electrons. These free electrons result in good electrical and heat conductivity. Coordination number is 8 or 12 (number of nearest neighbors). Ionic Bonding Found in compounds that are composed of both metallic and nonmetallic elements. Metallic element gives up valence electrons to the

Citric acid is used mainly for home use‚ for getting rid of lime scale (kettles‚ baths‚ toilets)‚ in hard water areas. Citric acid is a weak acid found in fruits such as lemons and oranges. Like other acids‚ citric acid can help you remove stains and rust deposits from toilet bowls without causing any damage to the porcelain surface. Citric acid contains just enough acidic concentration to get the job done without etching or damaging household surfaces in any way. It doesn’t harm the environment

Valuable Experience Gained During the Training Period The valuable experience that I gained during the training is when we are in the furnace of the boiler where the combustion takes place. The furnace is a internal parts of the boiler so we are taking the advantage to see what’s inside the boiler. We saw the generating tubes‚ bunker fuel injector‚ grates that we need to fix because of mis-alignment of the grates base. Grate is use for de ashing to avoid clogging up of the boiler. The second

Choose three physical properties that might vary considerably between samples of the same mineral and explain why such variability might exist. Hardness- Kyanite can contain differential hardness in each mineral. Color- Spahlerite can be many colors including‚ black‚ brown‚ red‚ green‚ white‚ or yellow. Habit- Pyrite can be massive‚ cubic‚ or octahedral 2) Using the information from Table 2.1 (chapter 2) in
