هدفت الدراسة الحالية الى التعرف ما اذا كان هناك تقبل اجتماعي للتلاميذ بطيئي من قبل اقرانهم العاديين؟ وكذلك معرفة ما اذا كان هناك فروق ذات دلالة في التقبل الاجتماعي بين افراد عينة الدراسة على وفق المتغيرات الاتية:

أ- العمر (9-13)

ب- الجنس (ذكور –اناث)

ج- المرحلة الدراسية

د- الحالة الاقتصادية (جيدة –متوسطة –جيدة جدا)

    ولغرض تحقيق اهداف الدراسة قامت الباحثة ببناء اداة تم جمع فقراتها من الادبيات والدراسات السابقة ولغرض ايجاد صدق وثبات الاداة اتبعت الاجراءات المتفق عليها لايجاد الصدق الظاهري ، والصدق التلازمي لفقرات الاداة.

كما تم ايجاد ثبات الاداة باستخدام طريقة كيودر– ريتشارد سون الصيغة (20).

وبعد ان تم التأكد من صلاحية الاداة للاستخدام ، قامت الباحثة بتطبيقها على عينة من التلاميذ العاديين من الصف (الرابع - الخامس) الابتدائي ممن تتراوح اعمارهم     (13-9) سنة ومن كلا الجنسين ، اذبلغ عدد افراد العينة (200) تلميذ وتلميذة.

ولقد تم المقارنة بين الوسط الحسابي للعينة مع الوسط الحسابي للمجتمع للتعرف على درجة التقبل الاجتماعي لدى إفراد العينة وبصورة عامة.فأشارت النتائج إلى عدم وجود تقبل اجتماعي للتلاميذ بطيئي التعلم من قبل اقرأنهم العاديين

واستخدمت الاختبار الثاني لعينتين مستقلتين في تحليل البيانات فيما يتعلق بالهدف الثاني للتعرف على دلالة الفرق في ضوء متغير العمر، استخدمت تحليل البيانات فيما يتعلق بالهدف الثاني من الدراسة للتعرف على دلالة الفرق في ضوء متغير الجنس, وكذلك استخدام اختبار للمقارنات البعدية لمعرفة دلالة الفرق في ضوء متغيري الحالة الاقتصادية والمرحلة الدراسية ، واظهرت نتائج الدراسة ان التلاميذ العاديين لايتقبلون زملائهم من بطيئي التعلم.

Determination of Antibodies (IgG, IgM) against Toxoplasma gondii in Some Iraqi individuals by using ELISA technique
...Show More Authors

A total of 258 voluntary blood donors (males 101; females 157) in the age range of 18-52 yr among males and 18-55 yr among females were examined for Toxoplasma gondii antibodies (IgG), and (IgM) by immunological technique (Enzyme linked Immunosorbant Assay) during the period from March 2009 to April 2010. This study covered a wide range of factors including immunological, age ,sex , place of residence and symptoms that may have a possible relationship with toxoplasmosis. Results presented in this study showed clearly that 38 (14.7%) of individuals participated in this study having IgG Toxoplasma Ab, among those 10 samples (9.9%) were males and 28 samples (17.8%) were females. Moreover, we found the prevalence of IgM seropositivity in th

Identification of Candida species Isolated From Vulvovaginal Candidiasis Patients by Chromgen agar and PCR-RFLP Method
...Show More Authors

This study focuses on diagnosis of Candida species causing Vulvovaginal Candidiasis using phenotype and genotype analyzing methods, and frequencies of candida species also using Vulvovaginal Candidiasis patients. 130 samples (100 from patients and 30 from non infected women) were collected and cultured on biological media. Identifying the yeasts, initially some phenotypic experiments were carried out such as germ tube, from motion of pseudohyphae and clamydospores in CMA+TW80 medium, API20 candida and CHROMagar Candida. Genomic DNA of all species were extracted and analyzed with PCR and subsequent Polymerase Chain Reaction - Restriction Fragments Length Polymorphism (PCR-RFLP) methods. Frequency of C. albicans, C. krusei, C. tropicalis , C.

Compensation of the Nonlinear Power Amplifier by Using SCPWL Predistorter with Genetic Algorithm in OFDM technique
...Show More Authors

The High Power Amplifiers (HPAs), which are used in wireless communication, are distinctly characterized by nonlinear properties. The linearity of the HPA can be accomplished by retreating an HPA to put it in a linear region on account of power performance loss. Meanwhile the Orthogonal Frequency Division Multiplex signal is very rough. Therefore, it will be required a large undo to the linear action area that leads to a vital loss in power efficiency. Thereby, back-off is not a positive solution. A Simplicial Canonical Piecewise-Linear (SCPWL) model based digital predistorters are widely employed to compensating the nonlinear distortion that introduced by a HPA component in OFDM technology. In this paper, the genetic al

Epicatechin product of Camellia sinensis leaves detection by thin layer chromatography and high performance liquid chromatography
...Show More Authors

The current study performed in order to detect and quantify epicatechin in two tea samples of Camellia sinensis (black and green tea) by thin layer chromatography (TLC) and high performance liquid chromatography (HPLC). Extraction of epicatechin from black and green tea was done by using two different methods: maceration (cold extraction method) and decoction (hot extraction method). Qualitative and quantitative determinations of epicatechin in two tea samples were investigated. Epicatechin identification was made by utilizing preliminary chemical tests and TLC. This identification was also boosted by HPLC and then quantified epicatechin in all ethyl acetate fractions of two tea samples. This research revealed the existence of epica

Research Octane Number Improvement of Iraqi Gasoline by Adsorption of n-Paraffins Using Zeolite Molecular Sieves
...Show More Authors

This study focused on the improvement of the quality of gasoline and enhancing its octane number by the reduction of n-paraffins using zeolite 5A. This study was made using batch and continuous mode. The parameters which affected the n-paraffin removal efficiency for each mode were studied. Temperature (30 and 40 ˚C) and mixing time up to 120 min for different amounts of zeolite ranging (10-60 g) were investigated in a batch mode. A maximum removal efficiency of 64% was obtained using 60 g of zeolite at 30 ˚C after a mixing time 120 min. The effect of feed flow rate (0.3-0.8 l/hr) and bed height (10-20 cm) were also studied in a continuous mode. The equilibrium isotherm study was made using different amounts of zeolite (2-20 g) and the

Comparative Study for Removal of Zn+2 Ions from Aqueous Solutions by Adsorption and Forward Osmosis
...Show More Authors

The aim of this paper was to investigate the removal efficiencies of Zn+2 ions from wastewater by adsorption (using tobacco leaves) and forward osmosis (using cellulose triacetate (CTA) membrane). Various experimental parameters were investigated in adsorption experiment such as: effect of pH (3 - 7), contact time (0  - 220) min, solute concentration (10 - 100) mg/l, and adsorbent dose (0.2 - 5)g. Whereas for forward osmosis the operating parameters studied were: draw solution concentration (10 - 150) g/l, pH of feed solution (4 - 7), feed solution concentration (10 - 100) mg/l. The result showed that the removal efficiency by using adsorption was 70% and the removal efficiency by using forward osmosis was 96.2 %.
