دسته ای از ترکیبات شیمیائی که مخصوصا با گسترش زندگانی جدید (ماشینی)اهمیت فرآینده ای پیدامی کنند، افزودنیهای مختلف غذائی میباشند که در صنایع مربوطه بکار گرفته می شوند بکارگیری بخشی از این موا تحت عنوان طعم دهنده ها بمنظور تامین طعم و مزه طبیعی درفرآورده های صنعتی تقریبا اجتناب ناپذیر گشته و همگام با توسعه تولیدات روبه توسعه می رود. یک شناخت سیستماتیک و جامع از خواص و آثار اینگونه مواد طبیعتا مست...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
Genomewide Variation in an Introgression Line of Rice-Zizania Revealed by Whole-Genome re-Sequencing
BACKGROUND Hybridization between genetically diverged organisms is known as an important avenue that drives plant genome evolution. The possible outcomes of hybridization would be the occurrences of genetic instabilities in the resultant hybrids. It remained under-investigated however whether pollination by alien pollens of a closely related but sexually "incompatible" species could evoke genom...
This study was conducted to produce a high percentage of genetically male tilapia through interspecific hybridization between Nile tilapia, Oreochromis niloticus and Blue tilapia, O. aureus and evaluate sex ratio, productive performance and heterosis of the progeny produced. The results revealed that sex ratios of the progenies of (♀ O. aureus x ♂ O. niloticus) and (♀ O. niloticus x ♂ O. aureus...
with the growth of more humanistic approaches towards teaching foreign languages, more emphasis has been put on learners’ feelings, emotions and individual differences. one of the issues in teaching and learning english as a foreign language is demotivation. the purpose of this study was to investigate the relationship between the components of language learning strategies, optimism, duration o...
in the present work we studied the birth order in progenies of lranian survivors of iraqi chemical attacks during a period from 1984 to 1989. then we compared the results with the birth order of the control group. despite a slight difference between the birth order in the two groups of progenies, this was not statistically significant. this does not mean, however, that there are no genetic cons...
in order to increase drought tolerance in bread wheat, an appropriate breeding program based on inheritance of drought tolerance is recommended. in the present study, nine bread wheat cultivars and their f2 progenies were evaluated in a randomized complete block design under normal and drought stress conditions. nine sensitivity/tolerance indices were calculated for studied genotypes and stress...
the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...
The construction of the 28-chromosome karyotype Dasypyrum breviaristatum was undertaken using multicolor non-denaturing fluorescent in situ hybridization (ND-FISH) and Oligo-FISH painting protocols. A novel wheat-D. line D2138 contained 44 chromosomes including a pair D. 6VbS.2VbL translocation chromosomes. Individual F2 F3 progenies cross between with wheat lines CM62, MY11 JM22, respectively,...
