Hydraulic fracturing (HF) is one of the methods for making coal mining operation safer and more economical. The most important parameters affecting HF process a seam are dip, thickness, uniformity, roof floor conditions, reserve strength. This paper presents development application fuzzy model predicting efficiency HF, considering aforementioned factors. In developed model, seams calculated as ...

Environmentally and technologically sulphur is a deleterious constitute in coal which makes it unsuitable for use in metallurgical industries unless the sulphur level can be reduced to the tolerable limit. Characterization of the various forms of sulphur and their associations in coal is an essential issue to find and propose a suitable desulphurization method. In this research, to evaluate sul...

“Atherosclerosis 2005: Recent Discoveries and Novel Hypotheses” We thank Drs Williams and Tabas for their interest in our work1 and agree that there is a substantial body of evidence supporting the role of hyperlipidemia in atherogenesis. In our review, we addressed this point and indicated that cholesterol may be sufficient to alter the homeostasis of the arterial wall in susceptible individua...

Pain in ICU patients should be managed effectively and safely. Fentanyl and Paracetamol are used frequently in ICU. However experience using IV Paracetamol in the setting of critically ill patients is limited. We evaluated the analgesic effect and adverse reactions of intravenous Paracetamol compared to Fentanyl in ICU patients with mild to moderate pain. Forty patients in a general ICU were ra...

the stereochemistry of the actinide elements has recently undergone considerable development and a wide variety of coordination numbers and geometries have been observed. this structural versatility arises from the lack of strong crystal field effects for the 5f-electronic configurations as well as from the large ionic radii of these metal ions, which change markedly with oxidation number, or a...
