A total number of 28 Awassi lambs were used in the research , those lambs were randomly distributed into 7 treatments, lambs fed on 4 experimental rations as follows the first ration was concentrated ration without any supplement (control), the second ration supplemented with 3.0 kg/ton of allicin, the third ration supplemented with 2.0 kg/ton ginger powder, the fourth ration supplemented with a combination of allicin (1.5 kg /ton) and ginger powder (1.0 kg/ton). Lambs fed by group feeding along with the experiment which had been lasted 91 days. The productive traits were studied such as a daily and total weight gain as well as feed conversion ratio and the consumed quantity of concentrated and rough feed. Twenty-one lambs were slaughtered (three lambs for each treatment)  to study the secondary cuts parts of the carcasses. Results revealed no significant differences among treatments in the initial and final weights and daily and total weight gains.  There were no significant differences in the consumed feed among treatments and feed conversion ratio. Results indicated also nonsignificant differences in weights of the head among treatments. Meanwhile, there were significant differences (P<0.05) in skin and legs weights among treatments. &nbsp

Effect of using Imported and Local Premixes on some Blood Parameters of Broiler

    أجريت هذه الدراسة لبيان تأثير استعمال مخاليط علفية مسبقة التحضير (Premix) خلطت مكوناتها محلياً وبتراكيز مختلفة (واطئ وقياسي وعالٍ) بنوعيه الممتاز (يستعمل في عليقتي البادئ والنامي) والعادي ويستعمل في عليقة الناهي كبديل عن المخلوط الأجنبي (بروفيمي، الممتاز والعادي) ومقارنة تأثيراتها في بعض المعايير الدمية لفروج اللحم.     استعمل في البحث 120 فرخاً من افراخ اللحم من سلالة روز 308 بعمر يوم واحد وزعت عشوائياً على اربع معاملات متساوية  احتوت كل معاملة على 30 فرخاً وبواقع مكررين لكل معاملة (15 فرخاً / مكرر). غذيت الافراخ على علائق التجربة اعتماداً المراحل العمرية للأفراخ (عليقة البادئ والنامي والناهي) والتي خلط فيها 2.5 % من أحد البريمكسات قيد التجريب  وكانت كالاتي :     المعاملة الأولى (T1) خلط فيها البريمكس الأجنبي والمستورد علامة بروفيمي أما المعاملات الأخرى T2 و T3 و T4 فقد خلط فيها علائق البريمكس المحلي الصنع والخلط وبثلاثة تراكيز (واطئ وقياسي وعالٍ) على التوالي،اجرى تكوين العلائق وخلط البريمكسات في معامل اعلاف ومختبر غدير بابل في قضاء المحاويل بأستعمال البرنامج الألكتروني الحديث البيست مكس (Best Mix) اصدار 2018، وفقاً لاحتياجات الطيور سلالة روز 308 بأعتماد الدليل الخاص بها أصدار 2014. جمعت عينات دم من الافراخ من جميع المعاملات بعمر 28 و 33 يوماً لغرض تقدير بعض المعايير الدمية. اشارت نتائج البحث الى وجود اختلافات معنوية (p<0.05) بين المعاملات في تراكيز خضاب الدم وعدد الخلايا اللمفية والبروتين الكلي وكلوكوز الدم وبمعنوية عالية (p<0.01) في تركيزي انزيمات الكبد ALP وAST بينما لم تحصل اختلافات في معايير الدم الاخرى مثل مكداس الدم وعدد الخلايا المتغايرة ونسبة الخلايا المتغايرة الى الخلايا اللمفية.     وسجلت افضل النتائج لصالح T4 (البريمكس المحلي ذو التركيز العالي) في معظم معايير الدم المدروسة لكلا السحبتين (يوم 28 و 33 من عمر الأفراخ)  سواءً الخلوية او الكيموحيوية ثم T1 (البريمكس المستورد البروفيمي)، أما ادنى المستويات المتشابهة فقد تميزت بها T2 و T3 اي البريمكس المحلي ذات التركيز الواطئ والقياسي على التوالي.   This study had been conducted to investigate the effect of using premix that been locally mixed by different concentrations (Low , Standard and high) of excellent quality (used in starter and grower rations) and normal which is used in the finisher as alternative for foreign premix (provimi , excellent and normal) with comparison of their effect on some blood parameters of broilers. Total number of 120, one day old broiler chicks , Ross 308 were allotted randomly on 4 equal treatments , each treatment included 30 chicks and each treatment included 2 replicates (15 chick/ replicate). Chicks fed on rations according to ages of chicks (starter, grower and finisher) in which 2.5 % of one premix added in the experiment which were as follow :      Treatment 1 (T1) in which the foreign premix was mixed as an imported one, provimi. Meanwhile, the other treatments T2 , T3 and T4 in which the local premix was mixed by 3 concentrations (low, standard and high) respectively.     Mixing and preparation of rations was done in Al – Ghadder laboratory and factory in Al – Mahweel/ Babylon by depending on Best mix program, 2018 according to birds requirement, Ross 308 by a special manual 2014. Blood samples were collected from birds at 28 and 33 days in all treatments.         Results revealed significant variations (P<0.05) between treatments in hemoglobin , lymphocyte numbers, total protein and blood glucose with a highly significant effect (P<0.01) for liver enzymes which include AST and ALT.      Meanwhile, there were no variation in other blood parameter such as PCV, numbers of Heterophils  and Heterophils / Lymphocyts ratio.      The best results were recoded for T4 (local premix of high concentrations) in most of studied blood parameters for both two blood collections (28 and 33 days of age of chicks). Which were cellular or biochemical then T1 (provimi imported premix). The lowest similar levels were characterized by T2 and T3 which were local premix, low and standard respectively

You measure what you value: how a Middle Eastern Polytechnic developed a sustainable review and improvement framework

Bahrain Polytechnic (BP) was established in 2008 to fill a gap in the Kingdom’s labour market for work ready graduates. Around that time newspaper reports highlighted a lack of quality and consistency in some private universities in Bahrain. Bahrain’s Qualifications and Quality Assurance Authority was in development so, in the absence of national guidelines, BP developed its own Quality Assurance Model to gain stakeholder confidence in the quality of its education. This comprised a Quality Management System with policies and procedures, and a self-review loop. The government was quick to redress quality concerns threatening the reputation of Higher Education in the Kingdom and today there are many external auditing agencies, each with their own paradigms and criteria. However, evidence that accountability audits produce quality improvement where it matters most - in the classroom - is lacking. An essential element in this failure is the dissolution of trust. This case-study tells of BP’s journey towards a more efficient and effective Self-Review model that shifts the focus from accountability and control to improvement and sustainability by taking into account Bahrain’s cultural context and the Polytechnic’s unique curricula and building on existing relationships to engender trust and commitment

Using and reasoning about social strategies in autism spectrum disorder in everyday situations

Although a substantial amount of previous work has been dedicated to the study of the possible theoretical mechanisms underpinning autism spectrum disorder (ASD), little research has examined the types of difficulties experienced by individuals in their everyday social functioning. University students with ASD and matched control participants performed the Social Strategy task. In this, they read a range of descriptions of social interactions, all ending with an awkward question asked by the story main character. The types of strategies they used to answer the awkward questions were examined. Compared to control participants, those with ASD used a more negative emotional tone in responding, generated more simple strategies including acquiescence or refusal, and fewer sophisticated strategies that considered all parties' perspectives. In a novel task condition, participants rank-ordered simple and sophisticated strategies, and gave justifications for their use. Rank-ordering did not differentiate the groups. Justifications given by those with ASD for simple strategies were more practical and less often character-based than those given by control participants; the groups did not differ in the justifications given for sophisticated strategies. The possible explanations of these findings and implications for informing current intervention programmes are considered

Expression in animal cells and characterization of the hepatitis E virus structural proteins

Hepatitis E virus (HEV) is a major human pathogen in much of the developing world. It is a positive-strand RNA virus with a 7.5-kb polyadenylated genome consisting of three open reading frames (ORFs). In the absence of an in vitro culture system, the replication and expression strategy of HEV and the nature of its encoded polypeptides are not well understood. We have expressed the two ORFs constituting the structural portion of the HEV genome in COS-1 cells by using simian virus 40-based expression vectors and in vitro by using a coupled transcription-translation system. We show here that the major capsid protein, encoded by ORF2, is an 88-kDa glycoprotein which is expressed intracellularly as well as on the cell surface and has the potential to form noncovalent homodimers. It is synthesized as a precursor (ppORF2) which is processed through signal sequence cleavage into the mature protein (pORF2), which is then glycosylated (gpORF2). The minor protein, pORF3, encoded by ORF3 is a 13.5-kDa nonglycosylated protein expressed intracellularly and does not show any major processing. pORF3 interacts with a cellular protein of about 18 kDa which we call 3IP, the pORF3-interacting protein. The significance of these findings are discussed in light of an existing model of HEV genome replication and expression

Organisational Justice and Organisational Commitment among Secondary School Teachers

The purpose of this study is to find the relationship between organizational justice (OJ) and organizational commitment (OC) among secondary school teachers. The sample consisted of 98 teachers working in 8 public secondary schools. OJ consists of three dimensions, namely, distributive justice (DJ), procedural justice (PJ), and interactional justice (IJ) which were used to measure the level of perception of justice among teachers, whereas to determine the level of commitment among teachers, the study used OC questionnaire. Pearson correlation and regression analysis methods were used to find the relationship and the impact of OJ on OC. The main findings of the study indicated that there is a positive and significant relationship between OJ dimensions and OC; DJ found highly correlated with OC. However, PJ and IJ positively and significantly predicted OC among secondary school teachers. The study could provide some significant literature contributions on the OJ and OC of secondary school teachers in developing countries
