Therapeutic development is increasingly taking advantage of the expanding field of human genetics. The genetic similarity between humans and non-human primates has increased the importance of the non-human primate as a model to develop new therapeutic modalities. DNA analysis of targeted genetic loci has revealed genetic variation and similarities that underlie observed idiosyncratic and genera...
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...
Observed or phenotypic trends in animal performance can be readily quantified from information collected from research or field populations. Phenotypic performance is determined by the collective impact of systematic effects that vary by trait, but may include herd, year, sex, and age; additive genetic effects; and a remainder that is referred to as the lack-of-fit or unexplained residual. It i...
Scrutinizing of different aspects in vegetative propagation of Iranian J. communis L. is of prime importance in order to prevent extinction of such valuable conifer. In this research, the effects of different seasons, gender, different chemical compounds (IBA, PBZ, putrescine and sodium nitroprusside) and three strains of Agrobacterium rhizogenes on ex-vitro rooting c...
Climate change has important effects on earth environment and human life. Therefor, investigation and study of climate change is very essential. This study investigated rainfall, temperature, relative humidity and wind variability by analyzing data for annual and monthly climatic factors collected at 13 synoptic stations (industrial cities of Iran) by using Mann-Kendall test. The results of mon...
The objective of this research was to estimate genetic parameters and trends for length of productive life (LPL), lifetime number of piglets born alive (LBA), lifetime number of piglets weaned (LPW), lifetime litter birth weight (LBW), and lifetime litter weaning weight (LWW) in a commercial swine farm in Northern Thailand. Data were gathered during a 24-year period from July 1989 to August 201...
—This paper proposes the implementation of a 3D virtual library, using open platforms such as OpenSimulator and Sloodle, applied to the integration of virtual learning environments. It also proposes their application to the creation of open libraries to share and disseminate the new dynamic nature of knowledge, in the understanding that 3D virtual worlds may contribute to the future of librarie...
INTRODUCTION Low-carbohydrate diets (LCDs) have regained popularity in recent years, but public awareness and perceived healthfulness of LCDs have not been explored. We describe population awareness, use, and perceptions of the healthfulness of LCDs and examine differences by sociodemographic and communication variables. METHODS Nationally representative data from the Health Information Natio...
The present data article describes high-school drop-out related web activities in Canada, from 2004 to 2012, obtained mining Google Trends (GT), using high-school drop-out as key-word. The searches volumes were processed, correlated and cross-correlated with statistical data obtained at national and province level and broken down for gender. Further, an autoregressive moving-average (ARMA) mode...
BACKGROUND Previous research suggests that certain populations, including rural residents, exhibit health care avoidant behaviors more frequently than other groups. Additionally, health care avoidance is related to sociodemographics, attitudes, social expectations, ability to pay for care, and prior experiences with providers. However, previous studies have been limited to specific geographic a...
