Pan African Medical Journal , 2011,
Abstract: Annular pancreas is a rare congenital anomaly characterized by the presence of ectopic pancreatic tissue surrounding the descending part of the duodenum. It is one of the few congenital anomalies of the gastrointestinal tract which can produce symptoms late in life. In adults, the factors initiating symptoms are recurrent pancreatitis, duodenal stenosis at the site of the annulus, or duodenal or gastric ulceration. We report a new case involving a 24-year-old woman hospitalised for epigastric pain, nausea and vomiting. Radiological examination was consisted with an annular pancreas. At operation a complete obstruction of the second part of the duodenum was found, caused by an annular pancreas, no other congenital anomaly of the intra-abdominal organs was noted. A gastroenterostomy was performed.

Abstract: The main aim of this work is to introduce the analytical approximate solutions of the water wave problem for a fluid layer of finite depth in the presence of gravity. To achieve this aim, we begun with the derivation of the Korteweg-de Vries equations for solitons by using the method of multiple scale expansion. The proposed problem describes the behavior of the system for free surface between air and water in a nonlinear approach. To solve this problem, we use the well-known analytical method, namely, variational iteration method (VIM). The proposed method is based on the use of Lagrange multipliers for identification of optimal value of a parameter in a functional. The proposed method provides a sequence of functions which may converge to the exact solution of the proposed problem. Finally, we observe that the elevation of the water waves is in form of traveling solitary waves.

Abstract: From the marine environment, woodlice gradually colonized terrestrial areas benefiting from the symbiotic relationship with the bacterial community that they host. Indeed, they constitute the only group of Oniscidea suborder that has succeed to accomplish their lives in terrestrial even desert surfaces. Herein they play an important role in the dynamic of ecosystems and the decomposition of litter. So to enhance our understanding of the sea-land transition and other process like decomposition and digestion of detritus, we studied the bacterial community associated with 11 specimens of terrestrial isopods belonging to six species using a Culture independent approach (DGGE). Bands sequencing showed that the cosmopolitan species Porcellionides pruinosus has the most microbial diversity. Screening demonstrated the predominance of Proteobacteria followed by members from Actinobacteria, Firmicutes and Cyanobacteria phyla. In fact we detected some symbionts like Wolbachia, Mycoplasma and Spiroplasma for the first time in a terrestrial isopod species.

Journal of Electrical and Computer Engineering , 2007, DOI: 10.1155/2007/45301
Abstract: A 2×1 LINC transceiver based on linear amplification using nonlinear components (LINC) architecture for wireless systems applications is proposed. The layout of the new architecture is presented and the simulation results show that the overall power efficiency of this architecture is superior by more than 300% when compared with that of a regular LINC amplifier. Also the adjacent channel power ratio (ACPR) is lowered to −64.2 dBc, compared to −26.1 dBc for regular LINC, which improves the system immunity against complex gain imbalances between LINC branches.

Survey of Students' Opinions as a Strategy for Improving Lerner-friendly and Defective Classroom Encounters
CM Anikweze
Ethiopian Journal of Education and Sciences , 2007,
Abstract: Based on the fact that virtually all the experiences to which learners are exposed in formal education are derived from a combination of psychological considerations, the expectations and prescriptions of the subject discipline, the society and its culture, the ideas of educational philosophers and curriculum experts, and that no conscious effort is normally made to consult the learners for opinions even at the secondary and tertiary education levels, the deschoolers have accused the school of teaching a hidden curriculum. Worried that even the prescriptions that are usually considered as contributory to effective teaching methodology are attributable to the ideas and principles enunciated by educational psychologists and philosophers, the researcher embarked on a pilot survey of students' opinions about teacher effectiveness. A questionnaire of the data blank to was administered to a sample of 80 Senior Secondary II students randomly selected from two Federal government Colleges (one boys' and one girls') located in the Federal Capital Territory Abuja. Effort was made to ensure gender balance in the selection of samples. The subjects were asked to state three objectives of being in school, three expectations from teachers and three objectives of being in school, three expectations from teachers and three hateful teacher-behaviors. Data were analyzed with descriptive statistics. Results showed that adolescents in secondary schools were fully aware why they were in school and could discriminate the qualities of effective teachers. The researcher recommends that a realistic perception of effective teaching methodology should be a blending of the perspectives from teachers' pedagogical insights, the students' perspectives and the perspectives of the society that is the consumer of the college output.

Madagascar Conservation & Development , 2012,
Abstract: This research examines local perceptions of social well - being in two forest - dependent communities near Zahamena National Park (ZNP), Madagascar. Key informant interviews were conducted to observe how local context, including community and ecological factors, influenced perceptions of social well - being. Overall, residents expressed a broad sense of decreased well-being as local forest resource access changed following the creation of ZNP. While one community was more dependent on forest and non - timber forest products for their livelihood, both communities believed lack of access to the park and its resources negatively affected local social well - being. Further, both communities felt ZNP provided few benefits to local residents. In addition, informants alluded to a sense of distrust of conservation managers and believed their needs and concerns were neither heard nor addressed by current conservation programs. Such data confirm people living in rural communities adjacent to protected areas have limited impact on conservation policies and initiatives on the island. Implications of this research suggest a reassessment of institutional conservation policy and practices to reflect locally held social traditions and community beliefs about conservation. RéSUMé Cette étude examine les perceptions locales de la qualité de vie dans deux communautés dépendantes de la forêt et vivant à proximité du Parc National de Zahamena à Madagascar. Des entretiens ont été menés pour analyser comment le contexte local, tant au niveau des facteurs communautaires qu’écologiques, a influencé les perceptions portant sur la qualité de vie. En général, les résidents ont constaté une baisse de leur qualité de vie depuis la création du Parc à cause du changement d accès aux ressources forestières locales. Une des communautés dépendait des produits forestiers ligneux et non ligneux pour sa subsistance et une autre communauté a estimé que le fait de ne pouvoir accéder au Parc et à ses ressources avait détérioré son niveau de vie. En outre, les deux communautés ont considéré que le Parc avait fourni peu d’avantages aux résidents. Les personnes interviewées ont également exprimé une certaine méfiance à l’égard des gestionnaires du programme de conservation qui, selon elles, n’ont répondu ni à leurs besoins ni à leurs préoccupations. Ces résultats confirment que les communautés rurales vivant à proximité des aires protégées ont une influence limitée sur la politique et les initiatives de conservation à Madagascar. Cette recherche suggère que la politique de conservation doit être réévaluée et qu’il y a lieu de rechercher de nouvelles pratiques permettant d’intégrer les traditions sociales locales et les croyances communautaires dans les actions de conservation.

Abstract: – a risk factor for stroke Review (1549) Total Article Views Authors: Ryan CM Published Date December 2011 Volume 2011:1 Pages 43 - 57 DOI: http://dx.doi.org/10.2147/CPT.S16490 Clodagh M Ryan Centre for Sleep Health and Research, University of Toronto/Toronto General Hospital, Toronto, Canada Abstract: Obstructive sleep apnea is a sleep breathing disorder characterized by recurrent and intermittent hypoxia with continued respiratory effort against a closed glottis. The result of this is a cascade of acute and chronic systemic pathophysiological responses that cause endothelial dysfunction, atherosclerosis and lead to cardiovascular and cerebrovascular disease. This article focuses on the clinical evidence linking obstructive sleep apnea and stroke and on the specific mechanisms perpetuating stroke risk in this population.

Abstract: rmacokinetics and pharmacodynamics of insulin analogs in special populations with type 2 diabetes mellitus Review (5096) Total Article Views Authors: Morello CM Published Date December 2011 Volume 2011:4 Pages 827 - 835 DOI: http://dx.doi.org/10.2147/IJGM.S26889 Candis M Morello1,2 1Skaggs School of Pharmacy and Pharmaceutical Sciences, University of California San Diego, 2School of Pharmacy, University of California San Francisco, Veterans Affairs San Diego Healthcare System, San Diego, CA, USA Introduction: The goal of insulin therapy in patients with either type 1 diabetes mellitus (T1DM) or type 2 diabetes mellitus (T2DM) is to match as closely as possible normal physiologic insulin secretion to control fasting and postprandial plasma glucose. Modifications of the insulin molecule have resulted in two long-acting insulin analogs (glargine and detemir) and three rapid-acting insulins (aspart, lispro, and glulisine) with improved pharmacokinetic/pharmacodynamic (PK/PD) profiles. These agents can be used together in basal-bolus therapy to more closely mimic physiologic insulin secretion patterns. Methods: This study reviews effects of the multiple demographic and clinical parameters in the insulin analogs glargine, detemir, lispro, aspart, and glulisine in patients with T2DM. A search was conducted on PubMed for each major topic considered (effects of injection site, age, race/ethnicity, obesity, renal or hepatic dysfunction, pregnancy, exercise, drug interactions) using the topic words and name of each type of insulin analog. Information was also obtained from the prescribing information for each insulin analog. Results: The PK/PD profiles for insulin analogs may be influenced by many variables including age, weight, and hepatic and renal function. However, these variables do not have equivalent effects on all long-acting or rapid-acting insulin analogs. Conclusion: Rapid-acting and long-acting insulin analogs represent major advances in treatment for patients with T2DM who require insulin therapy. However, there are potentially important PK and PD differences between the two long-acting agents and among the three rapid-acting insulin analogs, which should be considered when designing treatment regimens for special patient groups.
