nowadays green house gases such as carbon have the most effect on global climate changes that can be decreased by plant and soil carbon sequestration of rangelands. livestock grazing has high potential to decrease or increase carbon storage. so this research investigated the effects of enclosure on plant carbon storage in rangeland of enclosure (shah tappeh-chah mahmood) and no enclosure (chiro...

BACKGROUND Elastomeric pumps are often used to administer intravenous antibiotics in the outpatient setting, but effective infusion requires that the drug remain stable in solution throughout the procedure. OBJECTIVE To determine the chemical stability of ceftolozane/tazobactam when reconstituted and stored over an extended time in the AccuFlo (EMED Technologies, El Dorado Hills, California) ...

A kind of noise is dominated by broadband noise with low frequency tonal components. To achieve noise control on whole frequency band, it is necessary to implement hybrid control technique combining passive control and active control. There are three methods to combine passive control and active control, including active control in passive enclosures, active control outside passive enclosure an...

BACKGROUND There is a risk of drug sorption into an intravenous administration set composed of polyvinyl chloride (PVC), polyurethane (PU), or polyolefin (PO). This has implications on the dose of the active ingredient the patient receives, and thus therapeutic success. This study aimed to determine the plasma concentration of nitroglycerin and the effect of nitroglycerin on patients based on t...

In this paper, new results for two fundamental problems in the field of computational geometry are presented: orthogonal point enclosure query (OPEQ) in R and point location in orthogonal subdivisions in R. All the results are in the pointer machine model of computation. (1) In an orthogonal point enclosure query, a set S of n axes-parallel rectangles in R is to be preprocessed, so that given a...
