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 .

Show MoreFifty-Four paddy samples, 45 soil samples, and nine irrigation water samples of some paddy fields at Alfurat Alawsat Area, Iraq were collected to investigate the microbial quality including total count bacteria (TCB), molds and yeast, total coliform (TC), and E. coli bacteria. Paddy samples were processed at the laboratory level to produce rice at 32 and 36 whiteness, and the microbial quality of the produced rice was conducted too. The results showed that all irrigation water samples were overpassed the FDA limit for E. coli. All paddy samples were exceeded the good limit of TCB, but no sample exceeded the acceptable limit. Most paddy samples were exceeded the FDA limit for molds and yeast, and few paddy samples exc

Show MoreIn the present work, the surface properties of mixed binary surfactants containing sodium dodecylbenzene sulfate (SDBS) and Tween 80 (TW80) surfactants in aqueous solutions were studied at temperature 293 K using surface tension measurements. The critical micelle concentration (cmc) magnitude for both individual surfactants and their mixtures were established the obtained results revealed that the magnitude of cmc of the mixtures are less than the magnitude of individual surfactants and decrease with the increase in Tween 80 percent in solution which indicate the nonideal mixing of the two surfactants. The values of molecular interaction parameters and the mole fraction of surfactants in the micelle (X1) were calculated

Show MoreAbstract This dissertation examined the policy of American settlers toward Native peoples in the United States as one of the most complex issues in modern American history, as it was closely connected to the emergence of the new state and to the political, military, and economic transformations that followed the War of Independence, this policy developed within an expansionist context characterized by the pursuit of control over land and resources and the reorganization of geographical space in ways that served settler interests, in contrast to the marginalization of Indigenous presence and the erosion of their political and social systems, historical evidence demonstrated that relations between the two sides did not rest on fixed foundatio

The main advantages of airlift contactor compared with simple bubble column are ease of construction, low shear rate, high capacity, good mixing and liquid circulation without mechanical agitators and circulating pumps.
In this work, growth characteristics of Chlorella vulgaris microalgae were studied in an internal loop airlift photobioreactor for biomass production. The bioreactor operated under batch and semi-continuous culture mode using commercially available 20:20:20+TE NPK fertilizer as nutrients. The experiments were conducted to evaluate the growth rate and biomass productivity of
