سعى البحث الحالي الى التعرف على بعض الاضطرابات السلوكية والانفعالية وعلاقتها بالاستعمال المفرط للالعاب الالكترونية لدى تلاميذ المرحلة الابتدائية, إذ يواجه التلاميذ مشكلات سلوكية عديدة ،تظهر من خلال تعاملهم مع اقرانهم في البيت او في المدرسة والتي قد تتطور عند بعضهم وتتحول الى اضطرابات نفسية،مما يؤدي بهم الى ضعف التعلم وسوء التوافق في حياتهم المدرسية ويصبحون عُرضة للا صابة بالامراض النفسية ،إذا لم يتم تشخيصها بوقت مبكر وتوضع الحلول لمعالجتها أو الحد من آثاره وقد ترتبط هذه الاضطرابات بمتغيرات تؤثر في شخصية التلميذ قد تكون منها الافراط في استخدام الالعاب الالكترونية والتي صار الاطفال ينافسون الكبار في إقتنائها وشرائها ،إذ باتت تُشكل ولعاً وشيئاً أساسياً لايمكن الاستغناء عنه حيث هدفت الدراسة الى: 1-التعرف على مستوى الاضطرابات السلوكية والانفعالية (العدوان، الغضب ،العناد ) لدى التلاميذ . 2-التعرف على الفروق في مستوى الاضطرابات السلوكية والانفعالية (العدوان، الغضب ،العناد ) للتلاميذ (ذكور اناث) 3-التعرف على مستوى الاستعمال المفرط للالعاب الالكترونية لتلاميذ المرحلة الابتدائية. 4-التعرف على الفروق في مستوى الاستعمال المفرط على الالعاب الالكترونية للتلاميذ(ذكور اناث ) 5 –العلاقة الارتباطية بين بعض الاضطرابات السلوكية والانفعالية والاستعمال المفرط للالعاب الالكترونية لدى تلاميذ المرحلة الابتدائية) استخدمت فيها الباحثة منهج البحث الوصفي على عينة تتالف من (150) تلميذ وتلميذة ,اختيرت بالطريقة العشوائية,وبواقع (80) تلميذ و(70) تلميذة,للصفين الخامس والسادس الابتدائي ،حيث اظهرت نتائج البحث الى ان افراد عينة البحث لديهم مستوى عال من العدوان والغضب و مستوى منخفض من العناد وإن لديهم استعمالاً مفرطاً للالعاب الالكترونية، ولايوجد فروقا ذات دلالة احصائية بين الذكور والاناث في درجات مقياس الاضطرابات السلوكية والانفعالية (العدوان ،الغضب ،العناد) كما لايوجد فروقا ذات دلالة احصائية بين الذكور والاناث في الاستعمال المفرط للالعاب الالكترونية,وان هناك علاقة طردية موجبة ذات دلالة احصائية بين كل من (اضطراب العدوان والاستعمال المفرط للالعاب الالكترونية) و(الغضب والاستعمال المفرط للالعاب الالكترونية ), أي كلما زاد الافراط في استخدام الالعاب الالكترونية زاد اضطراب العدوان والغضب لدى التلاميذ ولاتوجد علاقة بين اضطراب العناد والاستعمال المفرط للالعاب الالكترونية لدى عينة البحث. استخدمت فيها الباحثة الاختبار التائي (T-test (لعينتين مستقلتين ,ومعاملات الارتباط بيرسون للتعرف على طبيعة العلاقة بين المتغيرين.ثم اوصت الباحثة على الحرص على توعية التلاميذ بمخاطر ممارسة الالعاب وبشكل مستمر وتأثيره على صحتهم النفسية والعقلية وتشجيع رغبات وميول التلاميذ وتنمية روح العمل لديهم بما يحتاج الى جهد جسمي أكثر مما يحتاج الى جهد عقلي عند التلاميذ ذوي النشاط الجسمي الزائد عن المعتاد .
This study focused on the role and importance of alkaloid compounds in Punica granatum peels which is one of many wide distribution medicinal fruits. Two kinds of pathogenic fungi were isolated from patients in Baghdad to be tested, also a type of extracts was prepared, alkaloids were isolated and partially purified and detected by two ways, a classic depended technique also used for determine these alkaloids, results showed an observed differences among extracts or treatments towards the fungi samples. So this study was one of the scientific applications to find natural alternative compounds that inhibit the growth of several pathogenic organisms that cause dangers and harms for human health.
Maulticollinearity is a problem that always occurs when two or more predictor variables are correlated with each other. consist of the breach of one basic assumptions of the ordinary least squares method with biased estimates results, There are several methods which are proposed to handle this problem including the method To address a problem and method To address a problem , In this research a comparisons are employed between the biased method and unbiased method with Bayesian using Gamma distribution method addition to Ordinary Least Square metho

Antibacterial activity of CNSs against Staphylococcus aureus and Escherichia coli was estimated. Higher inhibition zone of 18 mm and 20 mm were observed against S. aureus and E.coli, respectively, at a concentration of 2 mg/ml of carbon nanosphere after 24 hrs of incubation at 37 ºC. In vitro cytotoxicity experiment was performed on two parasite strains of Leishmania donovani and Leishmania tropica by using MTT assay. L. donovani revealed more sensitiv to the CNSs than L. tropica. An intermediate level of cytotoxicity of 51.31 % was observed when 2.4 mg/ml of CNSs was incubated with L. donovani, while weak cytotoxicity of 37.20 % was shown when the
... Show MorePosible interference of vamin with the activity of several antibiotics against E. coli was evaluated in vitro. In MBS- glucose medium, significant growth delay was induced by 8 ug/ml of terramycin (oxytetracycline- polymyxin B) and bactrim (trimethoprim-sulphamethoxazole), and by 16 ug/ml of refocin, lincomycin, and chloramphenicol. Rapid growth inhibition was induced by 32 ug/ml of all an- tibiotic tested separately. Significant inactivation of up to 64 ug/ml of licomycin and bactrim was in- duced by the addition of vamin at a concentration of 1:20 v/v of the medium. This effect was found to be due to the presence of specific amino acids in vamin. Among them is valine, leucine, isoleucine tyrosine, tryptophan, phenylalanine, cysteine, meth
... Show MoreMicroalgae have been increasingly used for wastewater treatment due to their capacity to assimilate nutrients. Samples of wastewater were taken from the Erbil wastewater channel near Dhahibha village in northern Iraq. The microalga Coelastrella sp. was used in three doses (0.2, 1, and 2g. l-1) in this experiment for 21 days, samples were periodically (every 3 days) analyzed for physicochemical parameters such as pH, EC, Phosphate, Nitrate, and BOD5, in addition to, Chlorophyll a concentration. Results showed that the highest dose 2g.l-1 was the most effective dose for removing nutrients, confirmed by significant differences (p≤0.05) between all doses. The highest removal percentage was

It was evident that development only occurred though the mastery of the basic single offence skills as well as the ability to perform compound skills accurately and consistently. Not paying enough attention to compound skills leads evidentially to weakness in the athlete's level that in turn leads to mistakes in performance. Six joiner games of the best four teams in Baghdad were filmed and analyzed. The results of analyzing the compound offence skills were as follows: There was some weakness in the athletes' ability in using compound offence skills specially receiving, dribbling and following through that
... Show MoreThe aim of this research is to estimate the parameters of the linear regression model with errors following ARFIMA model by using wavelet method depending on maximum likelihood and approaching general least square as well as ordinary least square. We use the estimators in practical application on real data, which were the monthly data of Inflation and Dollar exchange rate obtained from the (CSO) Central Statistical organization for the period from 1/2005 to 12/2015. The results proved that (WML) was the most reliable and efficient from the other estimators, also the results provide that the changing of fractional difference parameter (d) doesn’t effect on the results.
Bacterial strains were isolated from oil-contaminated soil, in 2018, these isolates were identified, and with the aim of finding out the ability of these isolates to degrede the oil compounds, the color change of medium which added to it isolates was read by the method of Pacto Bushnell Hans. Then the change in the petroleum compounds was read by gas chromatography, for the most effective isolates.
The nine isolated bacterial showed different degrees of color change, and the isolates (Pseudomonas, Bacillus, Micrococcus) outperformed the color change amount (78, 78, 77) %, respectively, compared to the control, and the three isolates together showed the best color change of 90.7. % Compared to the control, and the
... Show MoreThe adsorption of Malonic acid, Succinic acid, Adipic acid, and Azelaic acid from their aqueous solutions on zinc oxide surface were investigated. The adsorption efficiency was investigated using various factors such as adsorbent amount, contact time, initial concentration, and temperature. Optimum conditions for acids removal from its aqueous solutions were found to be adsorbent dose (0.2 g), equilibrium contact time (40 minutes), initial acids concentration (0.005 M). Variation of temperature as a function of adsorption efficiency showed that increasing the temperature would result in decreasing the adsorption ability. Kinetic modeling by applying the pseudo-second order model can provide a better fit of the data with a greater correla
