The transaction of collocation is tought for non-native speakers of a language and creates many problems for students, teachers and translators. The present study aimed to determine, examine and investigate the strategies and techniques adopted by students in translating collocations from English to Arabic. The data examined here, consisted of a translation test that comprised 9 relatively short sentences of a contextual collocations selected from different sources. Students were required to translate these collocations from English to Arabic according to Newmark approach (semantic & communicative approaches). So, the findings and results have shown that, students used or resorted various strategies in order to overcome the problems of rendering certain collocation expressions. In addition, the knowledge of collocation leads to the improvement of oral proficiency, listening comprehension, and reading speed.

Background and objective :Helicobacter pylori [H.pylori] infection is one of the most common chronic bacterial infections worldwide especially in the developing countries. This bacterium is the cause of many diseases such as MALT lymphoma, gastritis, peptic ulcers, and stomach cancer. According to recent reports, H.pylori infection may increase the risk of colorectal cancer. The current study aimed at investigating the association of H. pylori infection and the risk of colorectal cancer and adenomatous polyps. Methods: The current study was conducted on 52 patients with colon cancer as the case group and 200 subjects without pathological finding (i e, polyps, neoplasms, or inflammatory diseases) as the control group. Blood samples were collected from the patients in order to assess the presence of anti-H. pylori infection antibodies by the serum titer levels of anti-H. pylori IgG antibodies were measured using enzyme-linked immunosorbent assay (ELISA) with commercial kit by (Dia.Pro Diagnostic Bioprobes-Italy). Results: This study demonstrates distinct associations between H.pylori infection markers and CRC risk. While IgG seropositivity showed a significant 2.16-fold increased CRC risk (p = 0.019). Conclusion: This research finding IgG seropositivity may serve as a broader risk marker.

تقدم هذه الورقة بحثاً حول إطار عمل يعتمد على التعلم العميق للتصنيف متعدد الملصقات لأمراض الصدر باستخدام صور الأشعة السينية وبنية EfficientNet. يعالج هذا الإطار تحدي تشخيص الحالات المتعددة التي تتشابه في المظهر وغالباً ما تحدث معاً. يستخدم إطار العمل تقنية التعلم بنقل الخبرة (Transfer Learning)، مع إجراء ضبط دقيق لعدة متغيرات من نموذج EfficientNet (من B0 إلى B4) باستخدام مجموعة بيانات NIH ChestX-ray14. كما يوظف البحث تقنيات Focal Loss و Stochastic Weight Averaging لمعالجة اختلال توازن البيانات وتحسين قدرة النموذج على التعميم. يعتمد هذا النهج على آليات الانتباه (Attention Mechanisms) وتقنية Grad-CAM لجعل النتائج أكثر قابلية للتفسير، مما يثبت أن التوقعات تستند إلى ميزات سريرية هامة. حقق النموذج درجات عالية في مقياس ROC-AUC للحالات الأكثر وضوحاً مثل الانصباب (0.8545)، وتضخم القلب (0.8003)، والاسترواح الصدري (0.7820). ومع ذلك، واجه النموذج صعوبة أكبر في تصنيف الحالات الأكثر دقة مثل الارتشاح، والعقيدات، والالتهاب الرئوي. يؤدي إطار العمل بشكل يضاهي أو يتفوق على العديد من نماذج الشبكات العصبية التلافيفية (CNN) القائمة من حيث الدقة والكفاءة. يوفر هذا البحث سير عمل قوياً وقابلاً للتكرار لتطبيقات الأشعة، مع إمكانية استخدامه في مهام تشخيصية أخرى. كما تشير الدراسة إلى بعض المعوقات، مثل اختلال توازن الفئات والحاجة إلى دعم أفضل لاتخاذ القرارات السريرية، وتقترح تحسينات مستقبلية مثل تقنيات أفضل لتعزيز البيانات ونمذجة عدم اليقين.

Libya is country of desert and the arid climate makes it in extreme lack of surface water .Groundwater then bececomes a very important resource to meet the economical and agricultural demand ,which believed to be comparatively much cleaner and free from poliution than surface water , water poliution is a state of deviation from pure condition .whereby its normal function and properties are affected .The present study is amied at assesses the bacteriologcal pollution of ground water samples used for humans and animals at different 11 localities in Tripoli rigion , Libya .This study related to the bacteriologcal analysis revealed high values of toral bacterial count in groundwater samples from both tanks (648.85 cfu/ml)and wells (394.34cfu/ml) than standard count imit (100cfu/ml)for driking water by EPA. Naarly similar values of MPN of coliform (58.00MPN/100ml) and E.coli bacteria (0.20) from both tanks and wells, other than zero number per 100 ml set by WHO .Finally , we did not find pathogenic bacteria as Salmonella and Enterococci bacteria , but there is very littel number of pathognic bacteria as Staphylocooccus aurous (1.50) and Pseudomonas aerugnosa (0.07) isoaled from both tanks and wells samples . Hence ,it was concluded that . This research to analysis the bacteriologcal pollution of grandwater used for hnmans and animals for some different localities of Tripoli , Libya with review to the hygienic standards and suggest an approach for imporing and prevent such contamination . Microbiological lested ground waters samples are good and mostly suitable for domestic uses. the coliform and pathogenic bacterial contamination render this water unsatisfactory for driking purposes unless bacteriologically perfactly treated ,if necessary for consideration for utility.
