Studying the effect of Cyclone’s dimensions on the separation efficiency of wheat using computational fluid dynamics method
No full textCyclone is one of the most important components of pneumatic conveying system which is used for separating particles from gas stream. A CFD study was conducted to investigate the effect of Cyclone’s dimensions on its efficiency during wheat separation process. The main aim was alignment of the particles from different parts of the input and understanding the movement and separation of wheat particles. Cyclone type was high efficiency Stair and. It was designed in Solid works 2010 and meshed using Gambit software. In Fluent software based on a comparison with experimental results, the second order Reynolds stress model (RSM) was selected as the most appropriate method to model cyclone separation performance. It was found that at ratio of De/D=0.45 resulted high collection efficiency for particle size less than 4mm. In general at high 0.5 the separation efficiency for small seeds (d<4mm) was significantly less in comparison with the other ratios. Results showed that for wheat grains with approximate size of 3 mm and more, the ratio of h/d= 0.75 was the most appropriate option. However, for seeds size less than 3 mm h/d=0.5 was more appropriate. Considering the numerical results of this study, it was found that the smaller outlet diameter cyclone has a high collecting efficiency in comparison with large diameter cyclones
Prevalence of diseases in the canine referred to a private practice in Baghdad in 2015-2016
No full textDog ownership is an increasing aspect of veterinary practice in Iraq and it needs special attention since it lacks necessary information such as prevalence of various diseases and other basic information in this regard. In this study 258 dogs referred to a small animal private practice in 2015-6 in Baghdad were assessed. The mean ± SD of these dogs' age was 9.19 ±19.4 months and men presented more dogs than women (222 compared to 36). German shepherd dog was the most popular dog breed presented in this study while the most commonly presented health conditions were GI infections, Canine parvovirus, musculoskeletal conditions, respiratory infections, and canine distemper respectively. Additional 75 dogs were healthy and presented for check up and vaccination. Finally, German shepherd dogs were more likely to be presented with a disease compared to other breeds specially mixed breeds.
Assessment Of Differante Techniques For Oocyte Collection For Ivf In The Camel (Camelus dromedarius)
No full textThe aims of the present study were to compare between the harvested methods of oocytes of she camel ovaries and their effect on the numbers of oocytes collection, Grad of oocytes and ratio of maturation oocytes from AL-Najaf slaughterhouse from December 2017 to January 2018 in rutting season . The oocytes numbers, graded of oocytes and the rate of maturation oocytes. The collection of oocytes was done by aspiration, slicing and slashing .One hundred ninety quality oocytes (190) were recovered from 90 ovaries from she camel at age (4-7) years. The study revealed that slicing method yielded significantly different (p<0.05) number of oocytes from the others methods as 77 oocytes distribution Grad A, B and C 25 (32.4%), 30 (38.9%), 22 (28.7%), respectively. While the aspiration method yielded 54 oocytes distribution Grad A, B and C 22(40.7%), 18(33.3%), 14(25.9%), respectively. The slashing method yielded 59 oocytes distributed grad A, B and C 23(38.9%), 20(33.9%), 16(27.11%).The study appearance the aspiration method was better than the slashing and slicing method which obtained higher quality oocytes maturation percentages and significant different( p<0.05) compared to the other methods. From the forty oocytes cultured in TCM- 199, 18 oocytes showed cumulus expansion with cytoplasmic density and first polar body, The percentages 45% (18/40 mature oocyte). The slashing method collection culture 43 oocytes 15 oocytes showed cumulus expansion and cytoplasm density and first polar body the percentage 34% (15/43). Slicing method collection in same medium, out of 55 oocytes cultured only 11 oocytes showed cumulus expansion with cytoplasm density and first polar body. The percentage was 20% (11/55). There was a significant difference (p<0.01) between different collected method

أحمد بن هلال العبرتائي بين التضعيف والتوثيق
No full textتعتبر السّنّة الشّريفة أحد مصدري التّشريع والثّقافة الإسلامية، وهي تتلو القرآن الكريم في كونها الرّصيد العلميّ الّذي تتوارثه الأجيال إلى أن يرث الله الأرض ومن عليها.وتعتمد السّنة الشّريفة على النّقل والإسناد عبر رجال تحمّلُوا مسؤولية الاستماع والتّلقِي والحفظ والنّقل إلى الأجيال اللاحقة.وقد اجتمعت عدّة عوامل تاريخية أدّت إلى تسرّب الضّعف إلى إسناد الأحاديث، ممّا حدى بالعلماء إلى التّصدي لتقويم رجال الإسناد لغرض التّثبت من طرق الرّواية.ولهذا دونت الأصول الرجالية التي اهتمت برصد الرواة وتصدّت لبيان وثاقتهم أو ضعفهم ومدى إِمكان الاعتماد على روايتهم.من هنا كانت هذه الترجمة الوافية لأحد رجال أسانيد الأحاديث الشّريفة الواردة عن أهل البيت : ألا وهو: (أحمد بن هلال العَبَرْتائي) وقد انتظم هذا البحث على مقدمة ومبحثين هما
الإرادة ومفهومها في آية التطهير
No full textلمعني ومفهوم " الإرادة" في آية التطهير أثر مباشر في إثبات أو نفي العصمة عن أهل البيت(G). فالكثرة الكاثرة من علماء الإمامية يميلون إلي الرأي القائل بكونية الإرادة في آية التطهير ومن خلال هذا الموقف يثبتون العصمة للأهل البيت(G). في المقابل الكثير من علماء أهل السنة يميلون إلي الرائ القائل بشرعية الإرادة في آية التطهير وعلي ضوء ذلك الفهم ينفون العصمة عن أهل البيت(G).لذلك يسعي الباحث من خلال هذه الدراسة معالجة الآراء الواردة في هذا الصدد واثبات كونية الإرادة في آية التطهير وحللة الشبهة المنافية لعصمة الأئمة الأطهار متطرقاً إلي الأصوات المنادية القائلة بعصمة أهل البيت(G) عبر الإرادة التسديدية الإلهية و المقولات الآخري. وعلي ضوء تلك المعطيات ناقش الباحث تلك الآراء بالنقد والتحليل

Effect of Ramadan Fasting Upon Perforated Peptic Ulcer Patients: A Descriptive Analysis
No full textABSTRACTBackground: Perforated peptic ulcer (PPU) is relatively rare, but life threatening with the mortality varying from 10% to 40%. While common causes of peptic ulcer disease are H. Pylori, increased inadvertent use of NSAIDS, smoking and stress of modern life, the specific etiologic agent cannot be incriminated in the causation of its perforation.Objective: The aim of this study is to evaluate the effect of perforated peptic ulcer in fasting Muslims.Methods: This prospective analysis was conducted for the risk factors associated with perforated peptic ulcer (PPU) in patients attending Surgical Emergency hospital &Sulaimaniyah Teaching Hospital on 312 cases (246 male & 66 females) during the period of one month before Ramadan (Shaban), holy Ramadan and one month after Ramadan (Shawal) for ten successive years from 2006 to 2015. Descriptive analysis and Chi square test was used to find an association between studying variables.Result: The number of PPU per month was higher in Ramadan, 16.6 patients per month vs. 7.3 patients per each other month and also high among group 1 fasting patients. Predisposing factors played a major role in these differences.Conclusion: This study found that the incidence of PPU is relatively high among people who have predisposing factors, including young adults age, but earlier in non-fasting people , male gender, but no difference between the two groups in those using non -steroidal anti-inflammatory drugs, history of dyspepsia. Those patients have previous peptic ulcer disease diagnosed on esophagogastroduodenoscopy more prone to perforation. Long period day after day fasting, but not daytime length duration may increase PPU.Recommendations: This study recommends that the people with these risk factors must be well informed and need special care to avoid such complications. This study also suggests further studies regarding this subject.Keywords: Peptic ulcer perforation, risk factors, Ramadan fasts, duration of fasting, Shawal, Shaban
