Abstract Hydraulic conductivity (K) estimation of porous media is great significance in contaminant movement and groundwater investigations. The present study examines the influence effective grain size (d10) standard deviation (?) on K value borehole soil samples using 5.08, 10.16, 15.24 cm diameter permeameters. A statistical model was developed feasibility seven empirical equations evaluated...

OBJECTIVES To determine the effect of adding dexmedetomidine to bupivacaine for neuraxial anesthesia. METHODS Sixty-six patients were studied between April and May 2008 in the University of Jordan, Amman Jordan. They were randomly assigned into 3 groups, each receiving spinal bupivacaine 12.5mg combined with normal saline (group N) Dexmedetomidine 5 microg (group D5), or dexmedetomidine 10 mi...

Tetragenococcus halophila D10 decarboxylates aspartate to alanine, but T. halophila D10 derivatives generated by a curing treatment could not (Asd(-) derivatives). We observed by electrophoresis three plasmid bands in T. halophila D10; all Asd(-) derivatives lost the largest of these bands. This plasmid, pD1, has two SalI sites. We cloned and sequenced the 10 kb SalI fragment. The DNA sequence ...

The human pathogen Listeria monocytogenes forms biofilms that are relatively resistant to chemical sanitizing treatments. Ionizing radiation effectively inactivates planktonic Listeria, but no information is available on the relative efficacy of the process against biofilm-associated Listeria. The irradiation sensitivity of planktonic or biofilm cells was determined for L. monocytogenes ATCC 43...

OBJECTIVE To assess the value of serum LH measurements in early and late follicular phase as predictors of ovarian response and IVF outcome in patients treated with recombinant FSH with GnRH agonist (GnRH-a) pituitary down-regulation. DESIGN Retrospective cohort analysis. SETTING Institutional. PATIENT(S) Women undergoing 157 consecutive IVF cycles suppressed with leuprolide acetate (LA) ...

Gamma irradiation is widely used for sterilization; however, its effect on elimination of amplifiable DNA, an issue of relevance to molecular diagnostic approaches, has not been well studied. The effect of gamma irradiation on the viability of Staphylococcus epidermidis and Escherichia coli (using quantitative cultures) and on their DNA (using quantitative 16S rRNA gene PCR) was evaluated. Viab...

AIMS As the use of Point of Care Testing (POCT) devices for measurement of glycated haemoglobin (HbA1c) increases, it is imperative to determine how their performance compares to laboratory methods. This study compared the performance of the automated Quo-Test POCT device (EKF Diagnostics), which uses boronate fluorescence quenching technology, with a laboratory based High Performance Liquid Ch...

The human marrow produces approximately 1010 monocytes daily, and this production must be balanced by a similar rate of destruction. Monocytes/macrophages can undergo apoptosis after activating CD4+ T cells, suggesting one mechanism that may contribute to macrophage homeostasis. Previous reports indicate that Fas-Fas ligand interactions are the principle molecules mediating this response. Howev...

OBJECTIVE The use of the levels of hemoglobin A1c for the monitoring of glycemic control in patients with diabetes mellitus (DM) is an accepted method of clinical usefulness. A study was performed to assess the relative costs of hemoglobin A1c determination by diagnostic testing at or near the site of patient care (point-of-care testing, POCT) and using the standard hemoglobin A1c analyzer. MET...
