Veterinary cordon fences are used in Southern Africa to separate wildlife from domestic animals in order to prevent transmission of infectious diseases. Such fences are a control method recognized by the World Organization for Animal Health (OIE) for establishing disease-free zones in beef exporting countries. However, few studies have evaluated the ecological impact of these physical barriers ...

  Introduction:    Multileaf collimators (MLCs) are computer-controlled devices which are Useful and cost-effective tools for conformal therapy and intensity modulation radiotherapy (IMRT). Nowadays MLCs are important and standard configuration of the new medical linear accelerators which are substitute of conventional Blocks and has eliminated the ...

For some emergency situations an effective response can be reliant on sensor data (e.g. river level, traffic flow, weather conditions) to provide situation awareness, in order to help authorities make informed decisions. Gathering data in a traditional approach, i.e. using precise physical sensors, is a highly expensive task, involving procurement, installation and maintenance of a number of se...

BACKGROUND Human-elephant conflict (HEC) is a recurring problem that appears wherever the range of elephants and humans overlap. Different methods including the use of electric fences are used worldwide to mitigate this conflict. Nonetheless, elephants learn quickly that their tusks do not conduct electricity and use them to break down fences (fence-breakers). METHODOLOGY/PRINCIPAL FINDINGS I...

Fence method (Jiang and others 2008. Fence methods for mixed model selection. Annals of Statistics 36, 1669-1692) is a recently proposed strategy for model selection. It was motivated by the limitation of the traditional information criteria in selecting parsimonious models in some nonconventional situations, such as mixed model selection. Jiang and others (2009. A simplified adaptive fence pro...

abstract:â green spaces, especially urban gardens have been a subject of study in many countries for a long time, but the subject has been mostly overlooked in iran. therefore, this study tries to analyze the changes in land use and how we can protect green spaces (gardens) in jahrom in line with sustainable development in 1996-2006. the data in this study were collected through local investiga...

Movement of sand particles in nature creates many problems for humans. One of these problems is deposition of particles on rails that decrease the speed of the train or in some cases hampers the reversal of the train rails. In this paper the motion of sand particles over a railway track embankment, and how these particles settle on railway tracks are investigated. Moreover,the performance of di...
