Seasonally variations in Physio-chemical parameters of Al-Auda Marsh were investigated from November 2012 to July 2013. In this research examine pH, turbidity, EC, DO, BOD5 and Ca+2, Mg+2, NO2 , NO3 , PO4 , SiO3 ions. Six sites were randomly located and water samples. pH values varied from (7.3 ±0.0) in site 4 during autumn to (8.5±0.5) in site 6 during winter, EC values ranged from (2020±186) μ.s/cm in site 5 during autumn to (6390±875) μ.s/cm in site 6 during summer, mean turbidity data were found to vary from (6.5 ±1.8) NTU in site 4 in summer to (31.0 ±1.6) NTU in site 3 in autumn. DO highest mean value (10.9 ± 0.6) was for site 6 in autumn and the lowest value (6.5±0.9) mg/l for site3 in spring. In case of BOD5 highest and lowest mean values were (4.8 ±0.3) mg/l in site 3 during autumn and (1.2 ±0.3) mg/l in site 2 during winter. Mean Ca+2 ions ranging from (46±9.4) mg/l in site 4 during autumn to (361±19.6) mg/l in site 1 during summer, mean value of Mg+2 ion varied from (18 ±9.5) mg/l in site 5 in autumn to (274 ±44.2) mg/l in summer for site 1. Also, mean PO4-3 values of varying from (0.01±0.0) mg/l in sample of site 6 during winter to (0.3±0.08) mg/l in sample of site 6 during spring. The mean NO3 values was varied from (1.8±0.8) mg/l in site 6 during winter to (6.9 ±0.5) mg/l in site 5 during autumn while in case of NO2 were (0.1±0.0) mg/l in both sites 5 and 6 during spring to (0.35 ±0.01) mg/l in site 1 during autumn. SiO3 data found to vary from (1.0±0.5) mg/l in site 6 during autumn to (6.35 ±0.5) mg/l in site 2 during summer.
The present study was used 20 adult male rats that distributed to four groups (each group consist 5 rats); control group that administrated normal saline, rats group that exposure to X ray for two weeks, rats group that exposure to X ray with 50ug of green silver nanoparticles for two weeks, rats group that exposure to X ray with 100ug of green silver nanoparticles for two weeks. The results show high significant increased (P < 0.01) in levels of malonedialdehyied (MDA), and high significant decreased (P < 0.01) in levels glutathione (GSH) and significant increased (P < 0.01) in levels of Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), Alkaline Phosphatase (ALP), compared with control group.

Show MoreThe study was conducted over the period of Oct 2018 to Apr 2019 and is aimed for the detection and estimation of four hazardous Volatile Organic Compounds VOC (benzene, toluene, ethylbenzene, and xylene) so-called (BTEX) in samples collected from the produced water in the Al-Ahdab oil field in Iraq also to track their availability in the important natural water sources around the field. These compounds pose a risk to human health as well as environment. To avoid the laborious and tiresome conventional extraction methods, water samples were collected and concentrated using solid-phase extraction technique (SPE) which is a robust and cost-effective method of sample extraction with minimal exposure and handling of solvents and then to be analy

Abstract
The Classical Normal Linear Regression Model Based on Several hypotheses, one of them is Heteroscedasticity as it is known that the wing of least squares method (OLS), under the existence of these two problems make the estimators, lose their desirable properties, in addition the statistical inference becomes unaccepted table. According that we put tow alternative, the first one is (Generalized Least Square) Which is denoted by (GLS), and the second alternative is to (Robust covariance matrix estimation) the estimated parameters method(OLS), and that the way (GLS) method neat and certified, if the capabilities (Efficient) and the statistical inference Thread on the basis of an acceptable

The present study was conducted in order to focus on the effect of the addition of Carnitine and Niacin on some blood serum parameters of Common Carp Cyprinus Carpio. 48 fish carp mean weight 44.13 gm were distributed randomly on four feeding treatments (12 fish each) with replicates (6 fish each) in 8 glass aquaria. Treatments were as follows: fish were fed on basic diet without any addition and conducted as control (T1); addition of 200 mg Carnitine/ Kg diet, (T2) addition of 28 mg Niacin/Kg diet (T3), addition of a mixture of 200 mg Carnitine and 28 mg Niacin/ Kg diet as (T4).
