Tick-borne encephalitis (TBE) has become an increasing public health threat in recent years, ranging from Europe, through far-eastern Russia to Japan and northern China. However, the neglect of its expansion and scarce analyses of the dynamics have made the overall disease burden and the risk distribution of the disease being unclear in mainland China. In this study, we described epidemiologica...
عملکردهای زیستی پروتئین ها به واکنش های شیمیایی آنها با محیط پیرامون و سایر پروتئین ها بستگی دارد. به عبارت دیگر، ساختار سه بعدی و نحوه تاخوردن اجزای پروتئین ها در فضا، چگونگی این تعاملات را تعیین می کند. تشخیص صحیح الگوی تاخوردگی پروتئین با استفاده از اطلاعات استخراج شده از توالی آن، یکی از مسائل پیچیده و بحث برانگیز در زمینه بیوانفورماتیک می باشد. در این پایان نامه، سه روش نوین مبتنی بر الگور...
The cumulative effect of many local forest land use turnover reflects the character of the local site; disturbances can be estimated from an analysis of forest there is no evidence of region-wide gradients of regeneration distribution at the scale of the entire landscape. To gauge or clearance. the regional impact of forest clearance and regeneration, a Modern forest is concentrated along steep...
This study aimed to assess the impact of climatic variability on growth performance Fogera cattle at Metekel breeding and multiplication ranch. About 15-years meteorological data were collected from National Meteorological Agency. Then, heat stress (HS) condition ranch location was calculated by temperature-humidity index (THI). Moreover, all animals born calves that weaned 2005 2019 included i...

Maintaining and enhancing soil organic carbon storage can mitigate climate change while promoting forage growth. California has adopted incentive programs to promote rangeland practices that build carbon. However, there is no standard framework for assessing the baseline level of at ranch scale. Here, we use Ecological Site Description — a land-type classification system help managers set prior...
In East Africa, human population growth and demands for natural resources cause forest loss contributing to increased carbon emissions and reduced biodiversity. Protected Areas (PAs) are intended to conserve habitats and species. Variability in PA effectiveness and 'leakage' (here defined as displacement of deforestation) may lead to different trends in forest loss within, and adjacent to, exis...
conservation of biodiversity in protected areas will be more challenging if local communities are heavily dependent on them for various products and subsistence needs. this study estimated forest dependency and identified factors influencing dependency for households living around kasane forest reserve (kfr). data collected from 237 households were analyzed using logistic regression model. logi...
abstract marketing element’s contrastive behaviors toward price risk had considerable effect on marketing margin in a way that transferring increase in price to final consumer, reduces purchasing power and so consumption amounts of consumers. present study evaluated effective parameters on marketing margin in 2 level of ranch-processing and processing- retail of beef and lamb with consideration...
