The classification of bamboos based on floral morphology and reproductive characters is very hard due to erratic flowering behavior and unusually long reproductive cycle. The application of reliable and effective DNA molecular markers is highly essential to address this problem. In the present investigation, inter-simple sequence repeats (ISSR) markers were employed to study phylogenetic relati...
با وجود حجم بالای اطلاعات متنی، نیازمند سیستمی کارا جهت دسته بندی خودکار متون داریم. بنابراین، باید دسته بندی را طوری انجام داد که ضمن افزایش دقت، سبب کاهش زمان و هزینه شود. فرایند دسته بندی متون دارای گامهای پیش پردازش، وزن دهی، کاهش ویژگی و دسته بندی است که برای هر گام روشهای مختلفی تا کنون ارائه شده است. یکی از گامهای تعیین کننده در دسته بندی، کاهش ویژگیها است. این موضوع در زبان فارسی به...
background & aim: german chamomile is one of the most important medicinal plants. so, assessment of genetic diversity and relationship among the traits are very essential in chamomile breeding programs. determination of the best indirect selection criteria for genetic improvement of essence percent and dry flower yield of german chamomile (matricaria chamomilla l.) populations was investiga...
fulani ecotype chickens (fec) and yoruba ecotype chickens (yec) are the two major types of indigenous chickens in nigeria. they subsist under traditional animal husbandry and are thus liable to indiscriminate mating and consequently to loss of genetic diversity. fulani ecotype chickens (fec) and yoruba ecotype chickens (yec) were investigated to determine genetic variation at transferrin locus ...
background: stearoyl-coa desaturase (scd) is a key enzyme that converts saturated fatty acids (sfas) to monounsaturated fatty acids (mufas) in fat biosynthesis. despite being crucial for interpreting scds’ roles across species, the evolutionary relationship of scd proteins across species has yet to be elucidated. this study aims to present this evolutionary relationship based on amino acid sequ...
Determination of degree of relationship traditionally has been undertaken using genotypic data on individual loci, typically assumed to be independent. With dense marker data as now available, it is possible to identify the regions of the genome shared identical by descent (ibd). This information can be used to determine pedigree relationship (R), e.g., cousins vs. second cousins, and also to d...
Within analytical customer relationship management (CRM), customer acquisition models suffer the most from a lack of data quality because the information of potential customers is mostly limited to socio-demographic and lifestyle variables obtained from external data vendors. Particularly in this situation, taking advantage of the spatial correlation between customers can improve the predictive...
in this study, the relationship between teachers’ creative and critical thinking skills and their reflectivity in teaching was investigated. to this end, three questions were raised. these questions were intended to determine whether there was a significant relationship between teachers’ creative thinking skills and their reflectivity in teaching; whether there was a significant relationship be...
in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...
