After the oocyte is fertilized, the resulting one-cell zygote gives rise to all stem cell progenies. During the developmental process, these cells are necessary to generate all specialized tissues. However, some of them elude the specification cues and remain quiescent in the adult tissue, as long as the organism does not suffer from injury, illness, or specific cell-type depletion. Most adult ...

Technological approaches for detecting and monitoring fatigue levels of driver fatigue continue to emerge and many are now in the development, validation testing, or early implementation stages. Previous studies have reviewed available fatigue detection and prediction technologies and methodologies. As the name indicates this project is about advanced technologies in cars for making it more int...

Communication of information from the roadway infrastructure to vehicles is expected to enhance Automated Highway Systems (AHS) by supporting subsystem functions like vehicle motion control, multiple vehicle coordination, and vehicle navigation. A suitable communication channel is information coding in the lateral reference used for automatic steering and lane keeping control, e.g. in the magne...

Speed humps used as a tool of traffic calming technique that applied to force drivers to reduce their vehicle’ speeds at some locations. For developed countries, the implementations of speed humps are often used within residential areas as well as at locations of schools crossing.  For developing countries (e.g. Iraq), speed humps are used even at urban and urban highways.   This paper investig...

Highways provide commuter traffic and goods movement among regions and cities through wild, protected areas. Wildlife-vehicle collisions (WVC) can occur frequently when wildlife are present, impacting drivers and animals. Because collisions are often avoidable with constructed mitigation and reduced speeds, transportation agencies often want to know where they can act most effectively and what ...

Currently, increasing the efficiency of using fleet cars and functioning a road enterprise for construction highways by forming an optimal set machines based on developed normative labor intensity production vehicles elements highways, in mixed enterprise, is very relevant task. A technique has been optimizing "norm" input machines. Methodology standardizing equipment calculating rate developed...

Highways play a crucial role in economic development of any country. Besides this, highways are also one the causal agents wild life destruction. The present investigation was based on study mortality rate some selected animal groups road accidents viz., Mammals, Birds and Reptiles national state passing through Indian Thar Desert, survey biodiversity roadside fauna flora. focused effects popul...

environmental pollution of soil, plants and deposits around highways endanger urban environment through heavy metals as the by-products of vehicles and urban industries along with other pollutants. in this research, three main highways of tehran city; namely shahid chamran, shahid hemmat and yadegar emam which had the highest rate of vehicle transportation were selected and required sampling wa...
