Effect of some environmental factors on the tolerance of Bacillus subtilis to heavy metals
...Show More Authors

Abstract Twelve isolates of bacteria were obtained from samples of different soils and water amended with 100µg/ml of five heavy metals chlorides (i.e: Aluminum Al+2, Iron Fe+2, Lead Pb+2, Mercury Hg+2 and Zinc Zn+2). Four isolates were identified as Bacillus subtilis and B. subtilis (B2) isolate was selected for this study according to their resistance to all five heavy metals chlorides. The ability of B. subtilis (B2) isolate for growing in different concentration of heavy metals chlorides ranging from 200-1200 µg/ml was tested. The highest conc. that B. subtilis (B2) isolate tolerate was 1000 µg/ml for Al+2, Fe+2, Pb+2, and Zn+2and 300 µg/ml for Hg+2 for 24hour. The effect of heavy metals chlorides on bacterial growth for 72 hrs was studied. B. subtilis (B2) isolate had not affected by presence of pbCl2 FeCl2and AlCl2 in growth media. However, it was slightly affected by ZnCl2 during incubation period while mercury causes no bacterial growth. The effect of temperature on bacterial growth in media with heavy metals was studied. B. subtilis (B2) isolate showed growth in temp. range (30-50) °C with the present of the four heavy metals chlorides Al+2, Fe+2, Pb+2and Zn+2 while there are no growth in the presence of Hg+2 at all temperatures. The effect of different pH values on growth of B. subtilis (B2) isolate in media with heavy metals was studied. Results showed the ability of B2 isolate for growing in different pH values 4,7,9 with presence of the four heavy metals chlorides Al+2, Fe+2, Pb+2and Zn+2 in all pH values at conc. 1000 µg/ml and unability for growing in media with 300 µg/ml Hg+2. The ability of B. subtilis (B2) isolate for removal of heavy metals chlorides was studied and showed that the highest Zn+2 removal ratios 75% then Fe+2removal ratio 71% while Pb+2 has the lowest removal ratio 37%.

Effect of some sugars on carbapenemase gene expression in Pseudomonasaeruginosa
...Show More Authors

Forty eight isolates (41.02%) were obtained from 117 wound and burn samples. The isolates that showed high resistance for both antibiotic was two only that represent 4,1% from all isolates. The result of PCR product electrophoresis was referred that the gene is VIM gene. Lactose and raffinose showed double increasing in diameter of inhibition zone of imipenem with 1% that mean showed highest susceptibility that decreased with the concentration increasing, the same result were with meropenem. But no effect were detected on meropenem inhibition zone diameter. Mannose have no effect on the resistance in 1%, 3% and 7%. Results showed that only three case that increase the expression of gene, they were lactose at 1% concentration that increased

"Compared some of the semi-parametric methods in analysis of single index model "
...Show More Authors

As the process of  estimate for model and variable selection significant is a crucial process in the semi-parametric modeling At the beginning of the modeling process often At there are many explanatory variables to Avoid the loss of any explanatory elements may be important as a result , the selection of significant variables become necessary , so the process of variable selection is not intended to simplifying  model complexity explanation , and also predicting. In this research was to use some of the semi-parametric methods (LASSO-MAVE , MAVE and The proposal method (Adaptive LASSO-MAVE) for variable selection and estimate semi-parametric single index model (SSIM) at the same time .

Effect of Some Storage Conditions upon the Survival of Some Fungal Spores
...Show More Authors

Folic acid and multivitamin tablets containing Aspergillus flavus Penicillia spp. and Cladosporia spores were prepared at a compression pressure of 148 MN/m2 and stored at 35°C under different relative  humidifies (75,85, and 95)% within air tight containers, to study the effect of storage condition on them, as well as ,the estimation of the microbial level of the raw materials intended to be used in the two kinds of tablets . Result showed that some raw materials derived from natural origin were heavily contaminated with microorganism compared to that of synthetic origin ,the results also indicated the effect of relative humidity , types of fungal spore , and the hygroscopic nature of exicpient upon survival.

A relationship study of coronavirus (COVID-19) infection, blood groups, and some related factors in Iraqi patients
...Show More Authors

Many studies of the relationship between COVID-19 and different factors have been conducted since the beginning of the corona pandemic. The relationship between COVID-19 and different biomarkers including ABO blood groups, D-dimer, Ferritin and CRP, was examined. Six hundred (600) patients, were included in this trial among them, 324 (56%) females and the rest 276 (46%) were males. The frequencies of blood types A, B, AB, and O were 25.33, 38.00, 31.33, and 5.33%, respectively, in the case group. Association analysis between the ABO blood group and D-dimer, Ferritin and CRP of COVID-19 patients indicated that there was a statistically significant difference for Ferritin (P≤0.01), but no-significant differences for both D-dimer and CRP.

Effect of Lanthanum Addition on the Microstructure of Mg-4Al Alloy
...Show More Authors

 This research was to determine the effect of rare earth metal (REM) on the as-cast microstructure of Mg-4Al alloy. The rare earth metal used here is Lanthanum to produce Mg-4Al-1.5La alloy. The microstructure was characterized by optical microscopy. The phases of this alloy were identified by X-ray diffraction. The microstructure of Mg-4Al consists of α-Mg and grain boundaries with precipitated phase particles. With the addition of Lanthanum, three distinct phases were identified in the X-ray diffraction patterns of the as cast Mg-4Al-1.5La:  Mg, Al11La3, Al4La. The Mg17Al12 phase was not detected. The addition of Lanthanium increases the hardness and dec
