اصبحت وسائل الاعلام في ظل المتغيرات الجديدة قادرة على صياغة وعي وثقافة وهوية الشعوب الى حد كبير في المجتمعات المعاصرة , وذلك نظرا لما تتمتع به من اليات مختصة في التأثير والمتمثلة عموما في التكرار المتنوع للرسالة الاعلامية وقدرة الخطاب الاعلامي في معالجة القضايا المختلفة فضلا عن تقديم المعلومات وغزارتها وشرحها المستفيض , وقد بات من الواضح جدا مدى التأثيرات الكبيرة التي من الممكن ان يحدثها تعرض الافراد للمواقع الالكترونية للصحف العراقية المتنوعة والتي تشكل لدى الكثيرين جزءا اساسيا ضمن فعاليات حياتهم اليومية , وعلى الرغم من تعدد ادوات ووسائل الاعلام فيما يطلق عليه اليوم بالأعلام الجديد , الا انه من الملاحظ ان ابرز تلك الوسائل هي المواقع الالكترونية للصحف بمختلف اشكالها وتفرعاتها لما تمتلكه من سمات وخصائص جعلتها تتميز عن غيرها من الوسائل ومن المتعارف عليه ان لكل وسيلة اتصالية وظيفة مجتمعية تحققها في المجتمع الذي تتوجه اليه او الذي يتعرض لرسائلها الاتصالية , وهي تمثل الاداة الفاعلة في تشكيل اتجاهات هؤلاء الافراد او تعزيزها, لذا تتمثل مشكلة البحث في مدى فاعلية المواقع الالكترونية للصحف العراقية في تعزيز القيم الايجابية وترسيخها لدى افراد المجتمع, وتسليط الضوء على اهم القيم الايجابية التي يمكن ان تعززها تلك المواقع الالكترونية, في حين يهدف البحث الى تحديد فاعلية المواقع الالكترونية للصحف العراقية والكشف عن قدرتها في تعزيز القيم الايجابية لدى المجتمع, كما ويهدف الى تحديد ابرز القيم التي تحاول تلك المواقع تعزيزها في المجتمع ,وقد اعتمد البحث على اداة الاستبانة في جمع المعلومات والبيانات الميدانية لقياس مؤشرات مستوى الفاعلية للمواقع الصحفية الالكترونية , مستندا الى بناء اسئلة الاداة وفقا للأطر النظرية المعتمدة في البحث , واختتم البحث بمجموعة من النتائج منها ان مواقع الصحف الالكترونية قادرة على تعزيز قيم محددة ومهمة بالنسبة للمجتمع مثل قيمة حب الوطن و قيمة احترام التراث ام التوصيات فكان اهمها • ضرورة ان تقوم المؤسسات الحكومية ذات العلاقة مثل وزارة العمل والشؤون الاجتماعية المعنية بالمجتمع بالاتجاه الى توظيف المواقع الالكترونية للصحف العراقية من اجل بناء وتشكيل ترسيخ القيم الايجابية لما لهذه المواقع من تأثير كبير وفاعل في خدمة المجتمع .
This study investigated the outcome of Alstonia boonei stem bark on liver enzymes after inducing the Wistar albino rats with carbon tetrachloride (CCl4). This effect of plant extract was compared with silymarin – a drug commonly used for the treatment of chronic hepatocyte disorder. The plant sample was extracted with ethanol; acute toxicity study of the extract was performed on eighteen Wistar mice, while 30 rats were sacrificed for liver enzymes assay. The rats were divided into six clusters: each cluster has five rats, culster 1 served as control and was given 2 mL/kg b.w - distilled water; clusters 2 – 6 were CCl4 induced. Cluster 2 was untreated but served as the negative control while cluster 3 wa

Show MoreA. chroococcum isolate was examined for its ability to produce the hydrolytic enzymes chitinase, pectinase, protease, and lipase, in an effort to enhance the growth of fava bean (Vicia faba). Biological experiment was conducted in pots with complete random design (CRD). The experiment includes three treatments: control (plant without treatment) (P), NPK fertilizer (plant + fertilizer) (PF), and A. chroococcum inoculum (plant + A. chroococcum) (PA). These treatments were performed with sterile and non-sterile soil, which were planted with fava beans. At the end of experiment (seven weeks from planting), length and weight of plant shoot and plant root were calculated. The results show that the isolate wa

Seed morphology and ITS barcoding analysis were performed to assess their diversity and phylogenetic relationship. Sequence’s alignment of nrITS region from different accessions display high levels of genetic similarities. Cluster analysis could not group different accessions according to their geographical distribution. Nevertheless, the genetic barcodes are interestingly matched with the morphological features of the Ricinus seeds. In conclusion, seed morphology proved to be a valuable tool in evaluating biodiversity and phylogenetic relationship in plant species with different loca

Show MoreA freshwater bivalve plays a crucial function in aquatic habitats as the filtered water and burrowing mussels mix the sediment, thus increasing oxygen content and making the ecosystem healthier. The aim of the study is to see how chlorpyrifos affects biochemical markers in freshwater mussel Unio tigridis. About 180 individuals per taxon and water samples were collected from the Qandil water resource on the Greater Zab River, Erbil Province, Iraq. Once arrived at the lab, the individuals were kept in aquaria with river water and an air-conditioned room Temperature: 25±2 and Light: 12h/12h and acclimatized to laboratory conditions for seven days in aged tap water. The mussel's identification molecularly and the DNA sequence of t

Show MoreThe conducted research was done in Grda rasha field (Salahaddin University) for one month to compare the impacts of Alcea kurdica powder, Rifaxmine, and Ranitidine as anti-lesion and immune-strengthening agents on stress-induced quails which are affecting their growth rate and in severe cases causing gizzard erosion and deep intestinal lesions. To do that, 75 quails (12 weeks old) were grouped into six treatments with different additives. (T0-) = Negative control (Stress-induced Without treatment), (T0+) = Positive control (No stress inducing or treatment). T1= (treated with Rifaximine 200mg/L water mixed), T2= (treated with Ranitidine 200mg/L), T3= (treated with A.kurdica extract 100mg/L). The tested groups,

The prepared catalyst underwent a thermal treatment process at 400◦ C, while the reduction reaction under the same condition was done and the obtained catalysts were identified with transmission electron microscopy (TEM) and energy-dispersive spectroscopy (EDS). It has been found that the prepared catalysts have a dimension around 2.5 nm and the particles have uniform orders leading to high dispersion of platinum molecules .The prepared catalysts have been examined as efficient photocatalysts to degrade the Crystal violet dye under UV-light. The optimum values of Bimetallic Au –

In this study, TEC calculation was performed over Baghdad city, Iraq, using a combination of two numerical methods called composite Simpson and composite Trapezoidal methods. TEC was calculated using the line integral of the electron density derived from the International reference ionosphere IRI2012 and NeQuick2 models from 70 to 2000 km above the earth surface. The hour of the day and the day number of the year, R12, were chosen as inputs for the calculation techniques to take into account latitudinal, diurnal and seasonal variation of TEC. The results of latitudinal variation of TE
