Bibi Hakimeh oilfield consists of more than 145 oil producing wells. Its Oligomiocene Asmari reservoir is dominantly made of limestone. The act of a reverse fault on the north flank of Bibi-Hakimeh Field caused a significant thickness reduction in Gachsaran formation in the way that in some drilled wells, members No. 2, 3, 4, 5 and 6 of Gachsaran cap rock have been totally eliminated. This caus...

a high pressure drop happens when heavy oil with high viscosity moves through the oil pipeline. a variety of methods to avoid this pressure drop is available. one of which is injection of chemicals to reduce the viscosity and ultimately reduce pressure drop. using the pipesim software, the effect of dispersion of nano and micro-particles into the oil has been simulated to study the amount of th...

mazandaran province, northern iran, has been an area with highest prevalence of infectivity with human taeniasis during past decades. in order to assess current situation of taeniasis in the province by a method which can yield a correct estimation of infection rate, this study was performed by administrating anti-taenia drug, during 2003-2004. a total of 417 people were randomly selected from ...

the objectives of this paper were production of probiotic yoghurt using l. paracasei ssp. tolerans, and evaluation of ph changes, viable counts, and organoleptic properties of the produced yoghurt. it was observed that the ph decrease during the fermentation period was faster in the milk inoculated with l. paracasei ssp. tolerans plus starter culture. there was a gradual decrease in ph in both ...

During recent years, increasing exploitation of groundwater aquifers has caused a substantial and sharp drop in groundwater table in the plains of Iran. Artificial discharge of aquifer using flood spreading in plains is an approach that has been implemented in many parts of the country so far. In this method, by flowing flood into the aquifer, will control flooding and soil conservation. In add...

pistachio is one of the most important export items in iran, comprising more than 23% of iran non-oil exports. yazd is considered as the second biggest province of iran from the viewpoint of pistachio production, standing after kerman province. since frostbite phenomenon, especially, strong spring frostbite, has incurred many damages into pistachio gardens of this area, it is necessary to study...

Amorphous (Ni0.6Nb0.4)1−xZrx membranes were investigated by means of X-ray diffraction, thermogravimetry, differential thermal analysis and tensile modulus measurements. Crystallization occurs only above 673 K, and even after hydrogenation the membranes retain their mainly amorphous nature. However, after exposure to gaseous hydrogen, the temperature dependence of the tensile modulus, M, displa...

We show that whenever there is a sharp drop in the numerical rank defined by a personalized PageRank vector, the location of the drop reveals a cut with small conductance. We then show that for any cut in the graph, and for many starting vertices within that cut, an approximate personalized PageRank vector will have a sharp drop sufficient to produce a cut with conductance nearly as small as th...

Temperature dependencies of GaSb whiskers' resistance doped with Te to concentration of 1.7 × 1018 cm-3 were measured in temperature range 1.5-300 K. At 4.2 K temperature, a sharp drop in the whisker resistance was found. The observed effect is likely connected with the contribution of two processes such as the electron localization in the whiskers and transition in superconducting state at tem...

Telephone surveys made of 800-1,000 randomly selected residents of the United States and New Jersey in 2003 show a sharp decline in support for antipollution regulations, although pollution remains a major concern. This drop in support is associated with slowing of the economy, fear of terrorism, and other competing priorities. The leading proponents of maintaining strong environmental regulati...
