A large amount of gas is emitted during underground mining processes, so productivity decreases and safety risks increase. Efficient methane drainage from the coal seam surrounding rocks in mines not only improves but also leads to higher productivity. Methane must be performed when ventilation air cannot dilute emissions mine a level below allowed limits. The cross-measure borehole method one ...

In order to compare rectal and intravenous(IV) administration of diazepam for management of convulsions,a prospective cross-sectional case-control study was conducted on 94 convulsive infants and children referring to the Emergency department of the university hospital No.1 in Kerman.all children were randomly divided into two groups.the patients were matched with regard to the cause,type,durat...

This study includes a thorough systematic analysis of the ichnological record in the Late Triassic siliciclastic Nayband Formation of the Tabas Block, Central Iran. A total of 48 ichnospecies representing 28 ichnogenera are identified and their preservation aspects, paleoecological aspects, producers and behavioral aspects are discussed. The ichnofauna includes Arenicolites, Asterosoma, Bergaue...

A mathematical model of sorption of Zirconium and Hafnium cations mixture and elution of these ions from a cation exchange resin bed is developed. Sulfuric acid is selected as the eluent for selective separation of Zr and Hf in a packed bed of Dowex cation exchange resin. The column model is a dispersed plug flow model,and assumed to consist of randomly packed synthetic and spherical resin ...

Tissue repair is an essential component of wound healing and resolution of inflammation that, when uncontrolled, can lead to excessive scarring and organ failure (Majno, 1991). Indeed, exaggerated and persistent extracellular matrix (ECM) deposition in tissues is the hallmark of many pathologies linked to nonresolving inflammation, such as asthma, chronic obstructive pulmonary disease, and athe...
