Given that macrophages can proliferate and that certain microbes survive inside phagocytic cells, the question arises as to the post-mitotic distribution of microbial cargo. Using macrophage-like cells we evaluated the post-mitotic distribution of intracellular Cryptococcus yeasts and polystyrene beads by comparing experimental data to a stochastic model. For beads, the post-mitotic distributio...

Recently, special attention has been paid to artificial groundwater recharge in water resource management in arid and semi-arid regions. Water resources distribution in these regions is extremely uneven, both in spatial and temporal forms and groundwater is the only water resource and is a major constraint on economic and social development. Artificial groundwater recharge is considered an appr...

The consequence of human activities caused destructive and irreversible problems to the original state in the few past decades that has attracted the attention of all walks of life. The sinkholes are one of the mentioned effects in different parts of the planet such as Iran, Hamadan and especially have been happened in Kaboudarahang-Famenin plain. Researchers believe that the most important con...

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

the mahabad river watershed has been exposed to severe erosion as a result of landuse change. the aim of this study is to quantify the amount of sediment yield and the relationship between land use change and slope. different sources such as geologic and topographic maps, satellite images, hydrometric as well as meteorological data were used to extract and gather the information needed for this...

Features provide a comprehensive global overview of extent and diversity of grasslands. Analyzes how humans shaped grasslands through millennia of use and which role they play in present-day agriculture. Quantifies the role of grasslands as biodiversity hotspots as well as the drivers threatening these. Evaluates the ecosystem services grasslands provide e.g. in terms of soil protection and car...

Soil carbon and nitrogen contents play an important role in sustaining soil physical and chemical quality and help to have healthy environments. The continues conversion of rangelands to arable lands has the potential to change carbon and nitrogen sequestration. In this study to evaluate the effects of land use change on soil organic carbon and nitrogen stock, forty samples collected from north...

health care is considered a universal human right greatly emphasized in social welfare development in most countries. in this regard, public health care with its pervasive effects on the general level of communities' health is a top priority drawing the attention of planners and decision-makers a like. unequal and inharmonious distribution of such services leads to unequal accessibility ca...

The aim of this research is spatial Simulation and land subsidence susceptibility mapping using maximum entropy model in Jiroft and Anbarabad Townships. At first, land subsidence locations were recognized using extensive field surveys and subsequently the land subsidence distribution map was made in the geographic information system. Then, each of effective factors on land subsidence occurred i...
