تناولنا في هذا البحث الحافظ محمد بن وضاح الاندلسي، وأقواله في الجرح والتعديل / دراسة مقارنة مع اقوال ائمة الجرح والتعديل ،تكلمنا في المبحث الاول عن ترجمة موجزة عن  حياته: شملت  مولده ، ونسبه، وكنية ، ونشأته ، وشيوخه ، وتلاميذه ،وطلبه للعلم وثناء العلماء عليه، ووفاته. وفي المبحث الثاني: تحدثنا عن الرواة الذين كرر فيهم صفة التوثيق, وفي المبحث الثالث: تناولنا فيه الرواة الذين وثقهم مقارنة مع اقوال ائمة

The present study included the microscopic and molecular identification of Entamoeba histolytica by using specific primers to detect four virulence factors possessed by Entamoeba histolytica. Virulence factors included Active Cysteine proteinase, Galactose/N-acetyl-D-galactose-lectin, Amoeba pore C and Phospholipase. Titanium dioxide nanoparticles (TiO₂NPs) were synthesized from Pseudomonas aeruginosa which producing Pyocyanin pigment as a reducing agent to form it. After that we studied the ability ofTiO₂NPs to inhibit virulence factors production and curing the genes responsible for encoding them by using four different dose 2 ,3, 4, 6 mg/Kg and administered by intraperitoneal injection

يعد الباعث الدنيء من أدق المؤشرات التي تكشف عن مقدار الخطورة الاجرامية التي تنطوي عليه شخصية مرتكب الجريمة والتي على اساسها يقدر الجزاء ، والاصل ان الباعث الدنيء لاتأثير له على وجود الجريمة ولكنه يؤثر في مقدار العقوبة ، وللباعث الدنيء مجموعة من الخصائص والتي تكفل تميزه عن غيره من الحالات التي يكون لها دلالة على خطورة مرتكب الجريمة ، وللباعث الدنيء خصوصية في بعض الجرائم المعاصرة كونه يدخل في تكوين القصد ا

A chemical study was carried out to evaluate the efficiency of the liver enzyme concertation and uric acid level and its antagonists in the serum of the professors exposed to chemicals in the laboratories of the University of Samarra and their comparison with the healthy people. The research included 25 samples of the exposed professors and 20 samples as a group of officers.

              The results of the current study showed a significant increase in the level of   AST, ALT in the serum of professors exposed to chemicals compared to healthy people. The results showed no significant increase in

Seeds, beans, leaves, fruit peel and seeds of five plants (Ferula assa-foetida, Coffea robusta, Olea europaea, Punica granatum and Vitis vinifera, respectively) were extracted with four solvents (distilled water, 80% methanol, 80% acetone and a mixed solvent that included methanol, ethanol, acetone and n-butanol at proportions 7:1:1:1). Such manipulation yielded 20 extracts, which were phytochemically analyzed for total polyphenols (TP) and flavonoids (TF). The DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity (RSA) and DPP-4 (dipeptidyl peptidase-4) relative inhibition activity (RIA) were also assessed for each extract. The results revealed that mixed solvent extract of V.

The Detour distance is one of the most common distance types used in chemistry and computer networks today. Therefore, in this paper, the detour polynomials and detour indices of vertices identified of n-graphs which are connected to themselves and separated from each other with respect to the vertices for n≥3 will be obtained. Also, polynomials detour and detour indices will be found for another graphs which have important applications in Chemistry.

In this study, we made a comparison between LASSO & SCAD methods, which are two special methods for dealing with models in partial quantile regression. (Nadaraya & Watson Kernel) was used to estimate the non-parametric part ;in addition, the rule of thumb method was used to estimate the smoothing bandwidth (h). Penalty methods proved to be efficient in estimating the regression coefficients, but the SCAD method according to the mean squared error criterion (MSE) was the best after estimating the missing data using the mean imputation method

In this paper, we will provide a proposed method to estimate missing values for the Explanatory variables for Non-Parametric Multiple Regression Model and compare it with the Imputation Arithmetic mean Method, The basis of the idea of this method was based on how to employ the causal relationship between the variables in finding an efficient estimate of the missing value, we rely on the use of the Kernel estimate by Nadaraya – Watson Estimator , and on Least Squared Cross Validation (LSCV) to estimate the Bandwidth, and we use the simulation study to compare between the two methods.
