the influence of long-term mixed organic and inorganic contamination on soil microbial activity, community structure and genetic diversity was investigated in soil samples from a coke oven plant located in upper silesia, poland. the tested soils were heavily contaminated with polycyclic aromatic hydrocarbons (pahs) and heavy metals. the microbial communities were characterized using the phospho...

in this study, government budgets in the last 150 years have been examined based on leviathan state and the selection process theories. using this descriptive-historical method we evaluate the impact of financial behavior of government on development. in the first section of this paper, the concept of government nature has been defined and its influence on public finance is fully explained. mor...

background: spermatogonial stem cells are subpopulation of spermatogonial cells in testis tissue that support beginning and maintenance of spermatogenesis. ubiquitin carboxy-terminal hydrolase l1 (uchl1) could be a specific marker for identification of spermatogonial stem cells including spermatogonial sperm cells (sscs) in testis tissue and during the culture; therefore we undertook this study...

introduction: over the last decade, exposure to non-ionizing electromagnetic waves due to base station antenna has increased. this in vivo study was planned for evaluating the effects of whole-body exposure to 950 mhz field of gsm mobile phone system on rat dentate gyrus long-term potentiation. materials and methods: 24 naive male wistar rats (3 month old, 225|¡|25 g) were randomly divided in t...

sewage effluent is the carrier of huge amounts of n (0.09 to 0.16%), p (0.023 to 0.029 %), and k (0.11 to 0.18%) and as well as it is rich in organic carbon (3.27%). transfer of the toxic trace metal (pb) from the contaminated site can be seized out from the food chain through application of feso4.7h2o and caso4 in a larger area. the efficacy of the toxic metal immobilization through an applica...

Continual improvement is central to all organizational frameworks such as the IT Infrastructure Library (ITIL). Typically, data are collected through the lifecycle of a business process and analyzed asynchronously to identify long-term improvements. This position paper illustrates a limitation of this approach of continual improvement. When a support process is spawned to address a customer iss...

More than one hundred countries are using wind energy due to their easy implementation, cheap energy, and high energy efficiency. Implementation of FACTS devices in Wind Energy Conversion Systems (WECS) has been dramatically improved due to cooperative and accurate performance of FACTS devices. However, dealing with wind turbine faults promptly is crucial. Short-term and long-term faults may ha...

in this paper we examine the effect of the oil volatility, consumer price index (cpi) and industrial production on the stock market return in tehran stock exchange (tse). we used seasonal data in period 1378-1390 and auto regressive distributed method (ardl) for the short-term and long-term relationship between the variables. as results of research indicate, we find that there is positive short...

This paper classifies dipping tones in the framework of the Multi-Register and Four-Level tonal model. There are six types of dipping tones, four in Register M and two in Register L. The former includes (1) low dipping {323}, (2) back dipping /523/, (3) front dipping /324/, and (4) double circumflex /3232/, and the latter includes (5) creaky dipping {202} and (6) slack dipping /213/. After the ...
