The laparoscopic cholecystectomy nowadays is the method of choice for treatment of patients with cholelithiasis. This surgery involves different types of positioning of the anaesthetized patient. Our study was planned to compare the haemodynamic changes between the pre-induction period with the different positions of the anaesthetized patients during laparoscopic cholecystectomy. Thirty two (32) female patients of ASA physical status - 1 & 11, aged between 18 to 55 years, scheduled for elective laparoscopic cholecystectomy under general anesthesia, were enrolled in the study. All the patients were medicated with tablet clonazepam (0.5mg) on the night before surgery. On arrival to the operation theatre, baseline heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial blood pressure (MAP), and arterial oxygen saturation (SpO2) were recorded. The patients were then induced with Inj. propofol (1.5 to 2mg/kg). Endotracheal intubation was facilitated ...

Over the last thirty years, renewable energy sources have been attracting great attention due to the cost increase, limited reserves, and environmental impact of fossil fuels. In the main time, technological advancements, cost reduction, and governmental incentives have made some renewable energy sources more competitive in the market. Among them, wind energy is one of the fastest growing renewable energy sources. This work is applied to investigate whether WADI-SEIDNA region (North Khartoum, Sudan) is suitable to generate electrical power or not, according to a design and modeling of horizontal blade turbine. A detailed mathematical model of a squirrel-cage induction generator (SCIG) coupled to wind turbine system using vector control computing technique is also done. The performance of wind energy conversion system (WECS) is studied using simulation developed in MATLAB/SIMULINK.

A perspetiva dos alunos sobre a escrita constitui o eixo que percorre transversalmente este texto, a partir do contributo de estudos desenvolvidos em Portugal, desde a década de noventa até à atualidade. Nos primeiros três estudos considerados, essa perspetiva é captada no decurso do processo de escrita, focada na resolução de problemas por parte dos alunos, ao escreverem. As metodologias assentaram na escrita colaborativa e na integração, no processo, de estratégias facilitadoras da revisão. O segundo conjunto de estudos incide sobre as representações dos alunos em relação à escrita, considerando a pluralidade de contextos, géneros, recursos, saberes e atividades que implica. Metodologicamente, estes estudos mobilizaram textos explicitadores, questionários, entrevistas, diários, notas de campo. Os resultados mostram, em relação ao processo, uma progressão que torna salientes as limitações dos níveis de escolaridade mais baixos relativamente à reformulação e revisão. Quanto à relaçã...

This research in Phase II of its development aims to review, explore, identify and map the PLANCON Contingency Plans for Social Assistance prepared in the COVID-19 pandemic between 2020 and 2021 in the capitals of 26 States and DF to identify and explore the logical questions, techniques and policies for planning and managing preventive and mitigating measures for protection and civil defense in response to an emergency situation. Considered a natural disaster, the pandemic was inserted in a biological subgroup, with a sudden, significant and transitory increase in the occurrence of infectious diseases generated by viruses in the Brazilian Classification and Codification of COBRADE Disasters. The capillarity of the Single System of Social Assistance (SUAS) in the Brazilian social protection policy, in connection with the Single Health System (SUS) makes it possible to promote the development of two PLANCONs of Social Assistance for action on Covid-19 in 27 states and 5,570 municipal...
