Opis:
Lipid was extracted from the lipid containing muscle of Liner silver grunter (Pomadasys hasta) by solvent extraction and then purified by standard method. The physico-chemical properties of lipid sample were determined and compared with those of other standard fats and oils. Fatty acid composition of the lipid sample was investigated by Thin Layer Chromatographic (TLC) examination. Gas Liquid Chromatographic (GLC) examination was performed by the methyl esters mixture prepared from the lipid sample. The de-oiled muscle of the fish was studied for the determination of ash content, fiber content, moisture content and protein content. The lipid containing selected muscle was analyzed quantitatively for the determination of percentages of protein, cholesterol and minerals (N, P, K, Ca, and Na). The lipid containing muscle was also analyzed for the determination of the amount of eleven metals by using Atomic Absorption Spectrophotometric method. The lipid sample was evaluated by microbial activity (bacterial activity against nine bacteria and fungal activity against seven fungi).

Opis:
Dye sensitized solar cell (DSSC) shows great promise as an alternative to conventional p-n junction solar cells due to their low fabrication cost and reasonably high efficiency. DSSC was assembled by using natural dye extracted from red amaranth (Amaranthus Gangeticus) as a sensitizer and different catalysts for counter electrode were applied for maximum energy conversion efficiency. Annealing temperature and thickness of electrode were also investigated and optimized. Catalyst, annealing temperature and thickness were optimized by the determination of cell performance considering photoelectrochemical output and measuring current and voltage; then calculating efficiency and other electrical parameters. The experimental results indicated that samples having 40 μm electrode thickness and prepared at 450 o C annealing temperature showed the best performance.

Opis:
Lipid was extracted from the muscle of Cuttle fish by solvent extraction method and then purified by suitable conventional method. Various physical constants e.g. refractive index, viscosity, specific gravity, crude fat, crude fibre and ash contents and chemical parameters e.g. saponification value, saponification equivalent value, acid value, iodine value, acetyl value, peroxide value, thiocyanogen value, Reichert-Meissl value, Polenske value, Henher value, cholesterol content etc. of the lipid sample have been determined and compared with those of different standard oils. Fatty acids composition of the sample was investigated by Thin Layer Chromatography (TLC) method. The muscle lipid of Cuttle fish was found to contain palmitic acid, stearic acid, linolenic acid and erucic acid respectively with some other unknown fatty acids. Antimicrobial activities of the lipid were tested by standard method and found moderate to potential antibiotic and antifungal property in this lipid. The lipid containing muscle of Cuttle fish was analyzed quantitatively for the determination of percentages of protein and minerals (N, P, K, Ca) contents by modified Kjeldahl method.

Opis:
A hypothetical accidental case of a 3-MW TRIGA Mark-II research reactor has been assumed to assess the radiological consequences due to the deposition of 137Cs and 90Sr on ground, vegetation, milk and meat. The air concentrations in sixteen cardinal directions have been estimated where the maximum concentration has been found to be at 110 m distance from the core of the reactor for all the directions. Calculated maximum doses of 137Cs, 90Sr and both 137Cs and 90Sr have been found to be within the ranges of 0.005-0.014 μSv hr–1, 0.013-0.036 μSv hr–1 and 0.018-0.05 μSv hr–1, respectively for all the directions, which are below the measured background dose limit 0.25 μSv hr–1 and also within the IAEA acceptable dose rate limit of 0.5 μSv hr–1. The calculated low doses due to the aforementioned radionuclides can be considered negligible with regard to the radiation hazards. The relationship between total effective dose rate for various pathways (i.e. immersion, inhalation, ground deposition, and ingestion of contaminated vegetation, milk, meat) and air concentration in all the directions has been established. Obtained relation reveals that the total effective dose rate is directly proportional to the air concentration, and the overall proportionality constants for 137Cs and 90Sr radionuclides have been obtained as 0.57 and 0.28, respectively. This study might provide information on the radiological safety required for the radiation protection purposes of the people living in the vicinity of the reactor site.
