Freshwater creek is a freshwater stream located in North Cairns, and flows through the Redlynch area-which consists of rainforest, housing, farming and recreational areas. In order to have an indication of general health levels for Freshwater creek, measurements of the water parameters must be regularly checked. This is done to maintain health and prevent abnormal water qualities. Certain water qualities like dissolved nitrates, ammonia and oxygen will be measured at a site upstream from…

kind of physical forces which related to protein structure. The component of amino acid may be distinguished based on chemical nature of side chain group at the α-carbon atom. The side chain group determine the physicochemical properties, such as solubility, charge and chemical reactivity. Aliphatic (Ala, Ile, Lue, Met, Pro, and Val) and aromatic (Phe, Trp, and Tyr) side chain are nonpolar. Thereby, it is cause less soluble in the water. In contrast to amino acid with charges (Arg, Lys, his,…

Cancer is a disease that have been infecting people for centuries. It is also the leading cause of disease worldwide. According to the cancer research group in the uk, in the year 2012 there was an estimate of 14.1 million new cases of cancer. This was split 53% in males and 47% in females. Several cancer types exists and I will be focusing on breast cancer. In the years 2013 the American Cancer Society stated that there was 64,640 new in Situ cases and 232,340 new invasive cases. In situ cancer…

The Specimen Reception – where I spent most of my day-to-day work – is part of the Lab-Med group that is situated in the Central Pathology lab, and is made up of the biochemistry laboratory, the haematology laboratory – which includes cryobiology and coagulation, the microbiology lab, the histopathology lab – which includes cytopathology, the immunology lab, cancer molecular diagnostics, and transfusion medicine, as well as the Irish mycobacterium reference lab, and the national MRSA reference…

within the atmosphere and in oceans, by 2100 it’s predicted that the oceans will have a pH of 7.76-7.86. Nonetheless depending on where in the world you are the pH could differ slightly, due to the fact that carbon dioxide is more readily soluble (Solubility means the ability of a chemical substance, the solute to dissolve in another chemical solution the solvent. This forms the solution) colder water as opposed to warm meaning countries such as New Zealand are particular susceptible to the…

same results – both the prediction and the hypothesis were supported (the substance is a salt). Moreover, the prediction and the hypothesis about the dissolving of the powder in water were not supported. Compound X is insoluble (it has very low solubility). Lastly, both the prediction and the hypothesis about compound X’s reaction with hydrochloric acid (HCL) were supported. There is a reaction whose products are water and salt (and a gas – carbon dioxide). The reaction is as follows: X + 2HCL =…

Pentane and Diethylamine have many similarities, but they also have their differences. Pentane comes from the Greek word pente meaning “five” as the atom is comprised of five carbon atoms as shown in the formula C5H12. Some characteristics of the molecule is that it gives off a gasoline-like odor, generally does not have a color, and is a liquid. Pentane is commonly used in fuels, building construction materials, explosive materials, food packaging, paint, liquid chromatography, and toys just to…

Microstructure was observations of milk candy carried out using Scanning Electron Microscopy (SEM). Samples were observed samples that show the best treatment and the bad treatment by using the index of effectiveness. The microsture of the best and bad treatments milk candy were presented in Figure 1. Figure 1. Microstructure of milk candy. (A) the best treatment and (B) the bad treatment. (1) magnification 1500x and (2) to 2000x magnification. Figure 1 showed the spread protein matrix and…

where mCO2 is the mass fraction of CO2 in the solution, and MWsolution, MWbrine, and MWCO2 are the molecular weight of the solution, of the brine, and of CO2, respectively. Considering the definition of density as shown on 5.5, equation 5.3 can be modified to equation 5.6. ρ_CO2=MW_CO2/V_CO2 (5.5) "1" /"ρ" _" solution" =("1-" "m" _"CO2" )/"ρ" _" brine" "+" "m" _"CO2" /〖"ρ" _"CO2" 〗_" " (5.6) where ρ solution and ρ brine are density of solution and brine, MW CO2 and ρm CO2 is…

Dissolution test will be carried out in a simulated gastric fluid (SGF) using hydrochloride acid or a neutral buffer phosphate solution. The simulated gastric fluid without enzyme (SGF) at pH 1.2 and pH 3 containing sodium chloride and hydrochloric acid in 900ml deionized water will be prepared. Thus, the pH will be adjusted using hydrochloride(Ghazal et al., 2015). The simulated gastric media containing milk (whole milk, skimmed milk) will be prepared using an equal volume of milk and (SGF) pH…
