objective: diacylglycerol acyltransferase 1 is a microsomal enzyme that catalyzes the final step of triglyceride synthesis. the objective of this project is to check out the polymorphism at the exon 8 region of dgat1 gene using pcr-sscp technique in iranian water buffaloes (bubalus bubalis). recent activities have shown that a significant association between lysine at amino acid position 232 wi...

This paper evaluates the positioning performance of a single-frequency software GPS receiver using Ionospheric and Tropospheric corrections. While a dual-frequency user has the ability to eliminate the ionosphere error by taking a linear combination of observables, a single-frequency user must remove or calibrate this error by other means. To remove the ionosphere error we take advantage of the...

This work includes synthesis a series of some new derivatives triazine from reaction between the sulfur amino acid (L-cysteine) and different aldehydes in dry ethanol to obtain thiazolidine ring as diastereo isomers (Cis Trans)- 2- alkylthiazolidine-4- carboxylic acids (1).
 The (1) suffered esterfication presence drops concentrated sulfuric catalyst give esters :
 ethyl alkylthiazoli...

diallel crosses of eight genotypes of safflower were conducted and f1 and f2 generations were evaluated to estimate genetic parameters for seed-quality related traits including protein contents (%), fiber, ash and oil yeild. griffing’s methods 1 and 2 for f1 and f2 generations was used, respectively. sixty four genotypes including 8 parents and 56 f1 progenies, and half diallel crosses of f2 ge...

objective: to modify yeild of milk fat and to improve fatty acids profile of milk fat with supplementation of the diet with fish oil enrich in omega-3 fatty acids, especially, eicosapentaenoic acid (epa) and docosahexaenoic acid (dha). design: clinical trial. animals: ten dairy cows (treatment group, n=5 and control group, n=5). procedure: different amounts of fish oil were fed to the treatment...
