Motivation has been found to play a major role in determining student performance in the academic process. The aim of this study is to identify the intrinsic ＆ extrinsic motivational factors among medical students in the University of Sharjah. A Cross Sectional Study was conducted among university students of medical colleges in the period between February 2011 and March 2011. A total of 452 students （337 females and 115 males） were selected using the Quota sampling method equally between each college. A self-administered questionnaire consisting of 13 demographic questions, an agreement scale of 32 questions about the motivational factors and an open ended question asking students about what the university can do to help motivate them were developed. The most common intrinsic factors chosen by students were grade expectation （94%）, interest in material （92%） and leading an honorable life （88%）. While on the other hand the most common extrinsic factors were upcoming exams （88%）, family expectations （88%） and praise （82%）. The most common factors were similar between all students regardless of their major, gender, or performance. However, differences were visible in other factors such as in high performing students; rewards scored a 71.4% while low performing students scored it at 50%. It also shows that females consider praise as an important factor （86%） on the contrary males gave it a 72%. While the most common intrinsic factors showed to be grades, interest in material and leading an honorable life, the most common extrinsic factors on the other hand were upcoming exams, family expectations and praise.

本研究评价了用不同棉籽粉作铒料蛋白源饲养尼罗罗非鱼的长期效果.用带壳棉籽粉和去壳棉籽粉分别配制成等热值(475kcal总能量/100g饵料)的试验饵料(补充或不补充结晶体L-赖氨酸);粗蛋白含量约30%.用以鱼粉为主的饵料作对照.每一饵料组尼罗罗非鱼(20g)分相同三组进行重复试验.按2%～3%鱼体重量的日投饵量饲养130d.鱼粉饵料组鱼的增重率、特定生长率、饵料转化和蛋白质效率均显著优于用棉籽粉喂养的鱼.去壳棉籽粉饵料组鱼的生长情况和饵料转化显著优于带壳棉籽粉饵料组鱼,但蛋白质效率无显著差异.棉籽粉饵料中结晶体L-赖氨酸的补充对鱼类各方面的性能无显著影响.成本/收益分析结果表明带壳棉籽粉作为尼罗罗非鱼的饵料最经济,去壳棉籽粉次之,鱼粉最差.

Purpose: To evaluate patients with carcinoma of cervical stump (CCS) and analyse different clinico-pathologic factors affect prognosis. Patients and Methods: This study was carried out through review of clinical records of patients. Recorded data included information on age, tumor stage, presenting symptoms, size of tumor, histopathology, grade, type, cause of subtotal hysterectomy (STH), treatment and follow-up results. Staging according to International Federation of Gynecology and Obstetrics (FIGO) staging system was done through: PHySICAL examination, pelvic examination under anaesthesia, chest X-ray, magnetic resonance imaging (MRI) of the abdomen and pelvis, cystoscopy, rectosigmoidoscopy and intravenous pyelography. Prognostic factors as age, size of tumor, stage, lymph node (LN) involvement, pathological type, grade and type of CCS either true or coincidental were analysed through multivariate analysis. Results: 62% of patients are above 50 years with stage II in 48.7%. Squamous cell carcinoma was more common but 54% are of GIII. 89% were true CCS. Positive lymph nodes were reported in 27%. The predominant reason for STH was abnormal bleeding (73%). In about 95% of cases, women seeked medical attention because of symptoms and the most common presenting symptom was bleeding (54%). According to the stage and performance status of patients, treatment consisted of radiotherapy either external or interstitial, chemotherapy and chemoradiotherapy. Through multivariate analysis, the following was found to have adverse impact on survival: Coincidental type (P = 0.04), high grade (P = 0.03), advanced stage (P = 0.01), larger tumor size (P = 0.02), lymph node involvement (P = 0.029) and older age (P = 0.035). While pathological type was not (P = 0.52). After median follow-up of 52 months;5-year overall survival was 65%. Conclusion: CCS has a low morbidity. Adverse survival outcomes can be anticipated in those patients with: high grade lesions, advanced stages, large tu

The Multiple Sequence Alignment problem is considered to be an NP-Hard problem, requiring initially a specific encoding schema and design, as for any other of its siblings, to implement and run any of the main categories of heuristic. This paper intends to discuss our proposed generic implementation of the Tabu Search algorithm, a heuristic procedure proposed by Fred Glover to solve discrete combinatorial optimization problems. In this research, we try to coordinate and synchronize different designs/implementations discussed in many literatures, with some of the references mentioned in this paper. The basic idea is to avoid that the search for best solutions stops when a local optimum is found, by maintaining a list of non-acceptable or forbidden (taboo) solutions/costs, called Tabu list or Short-Term Memory (STM). In our algorithm, we attempt to add some executions tracing functionalities in order to help later analysis for initial parameters tuning. On the other hand, we propose to include the concept of a list called Long-Term Memory (LTM), so that some of the best solutions found so far can be saved, for search diversification.
