determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
OBJECTIVE To evaluate the effect of magnetic-activated cell sorting in cryopreservation-thawing protocols on sperm motility and cryosurvival rate. DESIGN Prospective-controlled study. SETTING Andrology department at a university-based medical institution. PATIENT(S) Ten healthy volunteer sperm donors. INTERVENTION(S) Sperm populations were separated using annexin-V magnetic-activated ce...
A series of phosphinic glutamate derivatives (e.g.LSP1-2111) have been proven to be potent agonists of metabotropic glutamate (mGlu) receptors and shown promising in vivo activity. However, so far all were synthesized and tested as a mixture of two diastereomers whose absolute and relative configurations are not known. In this study, the stereomers were separated on a Crownpack CR(+) column and...
In this study antimicrobial effects of Salivia mirzayanii and Saliva atropatana were evaluated against six gram-positive and gram-negative bacteria by immersion bioautography, cylinder plate and tube dilution methods separately. In bioautography method, essential oils of Salvia mirzayanii and Salvia atropatana were separated on silicagel TLC plates by toluene-ethyl acetate (93-7). In cylander p...
Given a set S of n points in IR D , D 2. Each point p 2 S is assigned a color c(p) chosen from a xed color set. The All-Nearest-Foreign-Neighbors Problem (ANFNP) is to nd for each point p 2 S its nearest foreign neighbors, i.e. the set of all points in Snfpg that are closest to p among the points in S with a color diierent from c(p). We introduce the Well Separated Color Decomposition (WSCD) wh...
