The variation in the composition of fresh tea leaves with season and shoot maturity, and to the applicability of cold storage (4C and 90% relative humidity [RH]) for the purpose of withering of tea leaves were studied. The results showed that the levels of polyphenol oxidase (PPO) activity and the polyphenolic content changed significantly with plucking season and shoot maturity. No significant...
The effects of growth of two strains of lactic acid bacteria on microbial flora of ground beef after packaging in air permeable packs were studied under workshop conditions. The strains isolated from dairy products were added to ground beef at a density of 104 CFU/g after identification and antibiosis test against indicator bacteria (Escherichia coli and Staphylococcus aureus). The two strains ...

In this research, the survival of probiotic microorganisms in yogurts stored at room temperature (cold chain interruption conditions) was studied. Milk inoculated with yogurt bacteria (mixed culture of Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus) and a single probiotic culture (L. acidophilus LA-5 or Bifidobacterium lactis Bb-12 or L. rhamnosus HN001 or L. paracasei...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
one very decisive factor in students’ academic destiny is the result they get at final term examinations. because of its importance, both students and teachers are curiously anxious about them. as normally it is the case, these final term tests are prepared hurriedly in short time by teachers which result in students’ dissatisfaction, complaining on how the test was different from their expecta...
"نگهداری در سرما" از معمول ترین روش های ذخیره ی زنبورهای پارازیتویید در پرورش انبوه این دشمنان طبیعی می باشد. هدف از انجام این پژوهش، امکان سنجی نگهداری در سرمای مراحل رشدی لارو سن آخر و شفیره ی جمعیت دوجنسی زنبور پارازیتویید(marshall) lysiphlebus fabarum به میزبانی شته سیاه باقلا، aphis fabae scopoli بود. همچنین چگونگی تاثیر دمای ثابت یا نوسان دار (انتقال روزانه 2 ساعت به دمای بهینه ی 1±21 درج...
to evaluate the effects of accelerated aging and cold stress on seed germination and seedling growth indices in five oilseed rape cultivars (hyola330, hyola401, hyola420, syn3 and pr401/15e), an experiment was carried out in a completely randomized design of three replications. results indicated that the cultivars were significantly different in germination percentage, seed vigour, germination ...
The genus AnthemisL. (Asteraceae) as medicinal plants are used both for pharmaceutical purposes and in folk medicine. In order to study of seed priming effects on seedling growth of two species of Anthemis spp., an factorial experiment based on randomized complete design with three replications was conducted under greenhouse conditions in Research Institute of Forests...
