The objective of this study was to assess the levels of antiMullerian hormone (AMH), Follicle stimulating hormone (FSH), testosteron, luteinizing hormone (LH), and estradiol (E2) as markers of spermatogenesis between fertile and infertile males. This study was conducted at (AlRamadi Teaching Hospital for maternity and children) and included 136 males partners of infertile couples. Samples were classified according to the WHO criteria of semen analysis into three groups; Azoospermia, Oligospermia, and normal(control). Assay levels of these hormones were made in the serum and the semen of each sample. The results showed that the level of AMH in serum samples was non-significantly decreased (P>0.05) in both Azoospermia and Oligospermia groups compared to control (6.74±3.21 ng/ml and 6.01±0.25 ng/ml vs. 12.81±7.69 ng/ml). While FSH and LH levels, there were non-significantly(P > 0.05) increased in both azoospermia and Oligospermia compared to control (FSH: 12.11±8.14 mIU/ml and 7.22±6.06 mIU/mlvs.3.14±1.27 mIU/ml; LH: 10.04±7.23 mIU/ml and 7.62±3.30 mIU/ml vs.5.57±2.03mIU/ml).In addition, there were non- significant differences (P> 0.05) of testosterone hormone level among the studied groups. Such, there was a non-significant decreased level of E2 (P> 0.05) in both Azoospermia and Oligospermiagroups compared to control (170.49±37.57 ng/ml and 137.20±53.92 ng/ml vs. 194.91±41.66 ng/ml).İn contrast to semen samples, the results of AMH showed a significant (P< 0.05) decreased level in both Azoospermia and Oligospermia compared to control (8.24±4.17 ng/ml and 8.85±4.79 ng/ml vs. 13.33±0.77 ng/ml). FSH level was non-significant (P> 0.05) increased in Azoospermia and Oligospermia compared to control (3.97±1.91 mIU/ml and 4.09±2.50 mIU/ml vs. 2.47±1.29 mIU/ml). Such, there were non-significant (P> 0.05) increased levels of LH and testosterone hormones in both Azoospermia and control compared to Oligospermia (9.35±6.02 mIU/ml and 5.99±4.43 mIU/ml vs. 4.06±2.82 mIU/ml), and significant (P< 0.05) increased level of E2 in both Azoospermia and Oligospermia compared to control (241.36±35.32 ng/ml and 220.86±48.96 ng/ml vs. 170.71±73.52 ng/ml).The study concluded that the AMH, FSH and E2 hormones levels in serum and semen samples may have been associated with the sperm production and may be a good marker for spermatogenesis, as well as Sertoli cell development. In addition, the age played a critical role in the level of the studied hormones.

Fourier Transform-Infrared (FT-IR) spectroscopy was used to analyze gasoline engine oil (SAE 5W20) samples that were exposed to seven different oxidation times (0 h, 24 h, 48 h, 72 h, 96 h, 120 h, and 144 h) to determine the best wavenumbers and wavenumber ranges for the discrimination of the oxidation times. The thermal oxidation process generated oil samples with varying total base number (TBN) levels. Each wavenumber (400–3900 cm−1) and wavenumber ranges identified from the literature and this study were statistically analyzed to determine which wavenumbers and wavenumber ranges could discriminate among all oxidation times. Linear regression was used with the best wavenumbers and wavenumber ranges to predict oxidation time.

Abstract
This work involves studying the effect of adding some selective organic component mixture on corrosion behavior of pure Al and its alloys in condensed synthetic automotive solution (CSAS) at room temperature. This mixture indicates the increasing of octane number in previous study and in this study show the increasing in corrosion resistance through the decreasing in corrosion rate values.
Electrochemical measurements were carried out by potentiostat at 3 mV/sec to estimate the corrosion parameters using Tafel extrapolation method, in addition to cyclic polarization test to know the pitting susceptibility of materials in tested medium.
The cathodic Tafel slope

Methodology: The sample consisted of (100) women, (50) considered as study group, and another (50) the control
group. A pre test was done for both groups (study and control), and then the study samples were exposed to an
instructional intervention and three-dimensional post tests and the length of time between each test 21 days in
the Institute and Hospital of Radiation and Nuclear Medicine. The questionnaire composed of three parts, first,

This study was conducted in Wasit governorate for the period between February 2012 to February 2013 to determine the impact of Castor seed oil at different concentrations 100, 75, 50 and 25% in inhibition of the growth of E. coli isolated from 52 male and female patients (2-70 yrs) attending Al Zahra Hospital and Al Karama Hospital in Kut city. Oil was extracted from seeds of Castor had the ability to inhibit E. coli isolated from patients presented with recurrent urinary tract infections . Zone of inhibition accomplishing was 9.06 mm in diameter.HPLC analysis revealed that the content of α-linolenic in Castor seed oil (18.90 μg\ml) was higher than other fatty acids followed by oleic. Perhaps this is why it able to inhibit E. coli; whi

In current study, the dye from flowers petals of Strelitzia reginae used for the first time to prepare natural photosensitizer for DSSC fabrication. Among five different solvents used to extract the natural dye from S. reginae flowers, the ethanol extract of anthocyanin dye revealed higher absorption spectrum of 0.757a.u. at wavelength of 454nm. A major effect of temperature was studied to increase the extraction yield. The results show that the optimal temperature was 70 °C and there was a sharp decrease of dye concentration from 0.827 at temperature of 70 °C to 0.521 at temperature of 90°C. The extract solution of flowers of S. reginae showed higher co
