A capillary plasma z-pinch as an alternative active medium of soft X-Ray lasers was studied experimentally and theoretically. The theoretical analysis was based on the self consistent solution of the so called “snow plow” model. The dynamics of pinched plasma is determined by the capillary parameters and by the time dependence of electrical current passing through it. The current time dependenc...

This study analyzed the performance of cabbage marketing in Abia State, Nigeria. Specifically the study sought to: describe socio-economic characteristics of cabbage marketers; identify marketing channels of cabbage; determine marketing cost components of cabbage marketers; determine marketing margins, market share and marketing efficiency of cabbage marketers; and determine socio-economic fact...

isolation of cell free fetal dna (cffdna) from maternal serum usually leads to very low concentrations of dna impeding further resolving through conventional methods of electrophoresis. although several protocols have been described for capillary electrophoresis (ce) of double stranded dna, they usually need using special polymers or coated capillaries which degrade over time. herein, we propos...

the purpose of this study was to evaluate the use of glass capillary micropipette (gcm) as a vessel forvitrification of bovine oocytes. cumulus-oocyte complexes (cocs) were obtained from slaughter-house andwashed 5 to 6 times in the washing medium (tcm-199 + 20% fbs) and randomly assigned to treatment andcontrol group. in the first step of vitrification, cocs were exposed to first vitrification...

human interferons (ifns) are key cytokines secreted by immune system. they have several effects such as antiviral and anti tumors activity, activating immune cells and healing of multiple sclerosis. the type ifns present in humans are α, β and υ. ifn β is a polypeptide, normally produced by fibroblasts and seems to be more species-specific than ifn . structural properties of i fns are importan...

two capillary zone electrophoresis (cze) methods were developed in this study, one using an acidic buffer (sodium citrate ph = 2.5) and the other using a basic buffer (sodium tetraborate ph = 9.8). the two methods were compared on the basis of repeatability and reproducibility of results and the cze method developed with the basic buffer was then selected for further studies. the method was ful...

one of the problems encountered in ce separations of basic compounds is the adsorption of analytes onto the negatively charged capillary wall which could lead to poor repeatability of migration time and peak area. additionally, separation of enantiomers of chiral of basic drugs is commonly carried out in low ph buffer which contributes to strong ionic interaction of the cationic drug ions with ...

background and objectives: fine needle aspiration cytology (fnac) is an established out- patient procedure used in primary diagnosis of palpable thyroid lesions. a modified technique fine needle capillary sampling (fncs) obviates the need of suction, is less painful, patient friendly and reported to overcome the problem of inadequate and bloody specimens. the aim of our study was to compare the...

introduction: lobular capillary hemangioma (lch) is a benign lesion of vascular origin. it rarely involves nasal cavity which most commonly manifests as progressive nasal obstruction and epistaxis. case report: in this report we present a case of lch of the nasal cavity which occurred approximately one month after delivery. there was no recurrence after complete endoscopic resection during one ...

This work focuses on the characterization of the rosmarinic acid (RA)-β-cyclodextrin (CD) complex in aqueous solution by (1)H NMR (1D- and 2D-ROESY), completed with studies by capillary electrophoresis (CE). From the (1)H NMR data, the stoichiometry of the complex was determined by a Job's plot and the binding constant was estimated from a linear regression (Scott's method). At pH 2.9, the resu...
