Current analytical free-flow speed models consider all rural two-lane highways as the same road type despite their different functional significance in network. The aim of this paper is to develop a prediction model for function limit and geometric characteristics classes highways. research was conducted on 50 representative sections two equipped with automatic traffic counters Serbia. In order...

There are over 60,000 miles (100,000 km) of coastal highways in the United States (US) that occasionally exposed to waves and water levels. Wise stewardship calls for integration engineering principles practices planning design these roads bridges make them more resilient. A new, 3rd, edition primary guidance document Hydraulic Engineering Circular No. 25 (HEC-25), entitled “Highways Coastal En...

recently, biofertilizer application is growing to meet sustainable agriculture goals. the present experiment was designed to evaluate four nitrogen levels (0, 60, 90 and 120 kg n.ha-1) as main plots, two supernitroplus biofertilizer levels) with and without biofertilizer) as sub-plots on yield and yield components of three sesame cultivars (naz, oltan and varamin (as sub-sub-plots in a split-sp...

background: cutaneous leishmaniasis (cl) is one of the most important neglected tropical diseases and a major public health challenge in iran caused by leishmania spp and transmitted by phlebotomine sand flies. the number of cl cases has shown an increasing pattern all over the country, including the district of varamin, southeast of tehran, iran. this study aimed to identify the leishmania spp...

the melon aphid, aphis gossypii glover (hemiptera: aphididae), is one of the most important pests of agricultural products in iran. in this study, susceptibility of melon aphid that collected from seven regions (yazd, varamin, mohammadshahr, esfehan, karaj, hashtgerd and ramsar) was compared to pirimicarb and malathion after 24 hours in 2009. bioassay experiments on adults were carried out by u...

In August of 1997, The US National Automated Highway System Consortium (NAHSC) presented a proof of technical feasibility demonstration of automated driving. The 97 Demo took place on car-pool lanes on I15 in San Diego, California. Members of the Consortium demonstrated many different functions, including: Vision-based road following Lane departure warning Magnetic nail following Radar reflecti...

Cell-to-cell communication is a crucial prerequisite for the development and maintenance of multicellular organisms. To date, diverse mechanisms of intercellular exchange of information have been documented, including chemical synapses, gap junctions, and plasmodesmata. Here, we describe highly sensitive nanotubular structures formed de novo between cells that create complex networks. These str...

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...
