Shear wave velocity is an important feature in the seismic exploration that could be utilized in reservoir development strategy and characterization. Its vital applications in petrophysics, seismic, and geomechanics to predict rock elastic and inelastic properties are essential elements of good stability and fracturing orientation, identification of matrix mineral and gas-bearing formations. However, the shear wave velocity that is usually obtained from core analysis which is an expensive and time-consuming process and dipole sonic imager tool is not commonly available in all wells. In this study, a statistical method is presented to predict shear wave velocity from wireline log data. The model concentrated to predict shear wave velocity from petrophysical parameters and any pair of compressional wave velocity, porosity and density in carbonate rocks. The established method can estimate shear wave velocity in carbonate rocks with a correlation coefficient of close to unity.
Five isolates (25%) of Klebsiella pneumoniae were isolated from urine samples. In addition also isolated bacteria were (10) 50% Escherichia coli, while (3)15% Proteus spp., (2)10% Pseudomonas aeruginosa. The ethanolic extract of Cinnamomum zeylanicum bark were tested against Klebsiella pneumoniae by using the well agar diffusion test, the alcoholic bark extract from (200 -12.5) mg/ml possessed antimicrobial activity against tested microorganism. At 200 mg/ml, and 100 mg/ml concentrations was diameter of inhibition zone rang from (18-26mm), (14-16mm) respectively, and these results compared to antibiotics Norfloxacin(10µg) inhibition zone (24-30mm), and Cefotaxim (10 µg) (26-27mm) as

Limestone is the main source of carbonates, while clay collected from arable land is the main source of silica. The marl in the Euphrates Formation was studied as an alternative to arable lands. Nine boreholes drilled and penetrated the marl layer in selected locations at the Kufa cement quarry. Forty-one samples of marl from boreholes and four samples of limestone from the closed area were collected. The chemical content of the major oxides and the hardness of the marl layer was very encouraging as a raw material for Portland Cement as they are SiO2 (17.60),

Seventy-six urine specimens were collected from of patients suffering from recurrent
urinary tract infections (UTIs). Specimens were bacteriologically analyzed, fifty
(65.8%) of isolated bacterial strains were belonged to E.coli. 100% of isolated
uropathogenic E.coli (UPEC)strains displayed a biofilm positive phenotype under
optimized condition using microtiter plate assay. 21 of E.coli strains classified as highly
positive biofilm producers (42%), and 29 (58%) as weakly positive biofilm producers.
A Simple, rapid and sensitive extractive and spectrophotometric method has been described for the analysis of diphenhyldramine –HCl (DPH) in pure form and in pharmaceutical formulations. The method is based on the formation of chloroform soluble ion-pair complex with Bromophenol blue(BPB) in a phthalate buffer at pH 3.0.The extracted complex shows maximum absorbance at 410 nm. Beer's law is obeyed in the concentration range 0.2-25.0 µg.ml-1. The molar absorptivity and Sandell's sensitivity for the system being 2.416x104 L.mol-1.cm-1 and 0.012µg.cm-2, respectively. The limit of detection was found to be 0.155 µg.ml-1. The proposed me

The classical autoimmune diseases, have adaptive immune genetic associations with autoantibodies and major histocompatibility complex (MHC) class II such as rheumatoid arthritis (RA), diabetes mellitus type two (DM II). Serum of99 males suffering from RA without DMII as group (G1), 45 males suffering from RA with DM II as group (G2) and 40 healthy males as group (G3) were enrolled in this study to estimation of alkaline phosphates (ALP), C-reactive protein (CRP) and Pentraxin-3(PTX). Results showed a highly significant increase in PTX3 levels in G1 and G2 compared to G3 and a significant decrease in G1comparing to G2. Results also revealed a significa

A three dimensional finite element analysis, by using finite element code ANSYS, is employed to investigate shear lag phenomenon and the resulting effective slab width adopted in the classical T-beam approach. According to case studies and comparison with limitations and rules stipulated by different standards and codes of practice it is found that web openings presence and panel proportion are the most critical factors affecting effective slab width, whereas concrete slab thickness and steel beam depth are less significant. The presence of web opening reduces effective slab width by about 21%.
