MHD peristaltic flow of a conducting fluid with heat transfer in a vertical asymmetric channel through porous medium is investigated under long wave length and low Reynolds number assumptions. The flow is examined in a wave frame of reference moving with the velocity of the wave. The channel asymmetry is produced by choosing the peristaltic wave on the walls to have different amplitudes and phase. The analytical solutions have been computed for the axial velocity and temperature. The pressure rise and the frictional force are obtained. The effects of different parameters on the pressure rise, velocity, temperature and shear stress are discussed numerically. The phenomenon of trapping is further investigated.

The aim of this paper is to adopt analytic-deductive method to examine some clues on the existence of the Supreme being in the beliefs and religion of the Ibani; the implication is that hasty generalization and superfluous assumptions, has led some scholars to maintain that the idea of the Supreme Being is of Western importation. Christianity and Ibani traditional philosophy play a major part in contributing to the debate, although the contribution of Christianity outweighs that of the traditional Ibani because Christianity has the epistemological advantage of supernatural revelation and also has the advantage of early documentation. Nevertheless, prior to Christianity, the raw materials for the philosophy of God were stored in oral tradition and highlighted by a highly evidenced and philosophical culture.

This paper presents the impact of Unified Power Flow Controller (UPFC) on transient stability improvement in the Nigeria 330KV transmission network. UPFC is a Flexible AC Transmission System controller (FACTS) that can regulate the Power flow through the Line by controlling its Series and shunt reactance. In shunt connection it has Static Synchronous Compensator (STATCOM) and in the series, Static Synchronous Series Compensator (SSSC) is employed and can independently control the Line Power Flow in order to improve transient stability of the system. This network which consist of 17 generating stations, 41 buses and 40 transmission lines was modeled and simulated using PSAT and Matlab Version 7.5. Fault was initiated with and without UPFC and result showed that Transient Stability of the system is improved.

Genital tract tuberculosis is an unusual cause of infertility. It affects a young woman with an immunodeficiency. The increase in the level of the CA 125 marker can be found. Ultrasound, CT scan and magnetic resonance imaging (MRI) are not specific. We report a new case of fallopian tuberculosis revealed by amenorrhea and chronic pelvic pain.

Population Increasing, garbage producing and land decreasing for burial is problems and issues of today's big cities that the need for recycling and waste reduction techniques in production and landfill and is increasingly considered Day-to-day accordingly. One of the most useful methods in the field of reuse of dry garbage is to segregate from origin by Citizenries and create incentives for their participation increases. For example, the daily productions of 15 tons of paper in Mashhad shows more and more need to review and develop appropriate strategies to encourage citizens and separation of garbage. one of the activities of Mashhad ' municipality is in the field of solid waste transfer station so that in addition to encouraging citizens provide the receive possibility of suitable use of municipal Incorruptible substance solid waste . Thus the present paper is discussed the locating of the stations with respect to the criteria of population, their accessibility, physical analysis of garbage and determine distance to other stations in municipality 's zooms by using GIS software. The results of this research suggest the 1,11,9 and 8 zones as appropriate places to create new stations to collect dry waste.

Necessity is the mother of invention. The superiority of human over other creatures lies in the fact that he can make tools to satisfy his needs. To make bread, they needed to crush the wheat into powder. To achieve this end, the hard-working people of Khuzestan Province tried to use hydropower by building mill and operating it. The utilization of Eco-friend Energy plays the essential role in the environmental protection in the contemporary age, so that many countries have given the importance to such energies in their national programs. The study demonstrates that the issue has been considered in Iran from the early ages. The recognition of watermills utilization experience in the southwestern region of Iran and especially the northern part of Khouzestan province reveals that the use of water energy has been adapted with the daily needs of residents. With regard to the water power transmission mechanism in the studied local watermills known as Asyab, a same mechanism in all two types of Asyabs is recognizable. Based on the study main achievement, such a power transmission mechanism can be applied in the contemporary age even in other countries to replace the energies derived from the fossil fuels with the water energy as a Renewable and Eco-friend Energy Finally, not only, to preserve such valuable historic remnants is an aid to attract Iran and glob tourists and the people who are interested to know about them, but, Capitalizing on the rewarding continental conditions of Dezful city leads to take economical steps to make a steady progress in using modern technologies such as electricity power.

Climate change and climate variability and financial institutions’ unwillingness to give loans have resulted in many farmers losing confidence in dry land agriculture. Traditional crop insurance methods have also presented challenges due to the risk related to adverse selection and moral hazard resulting in high transaction costs for individual assessment. This study focused on developing a weather index based insurance model that uses artificial neural networks to estimate potential evapotranspiration (ETO) and consequently yield reduction due to moisture stress. Weather data from 2012 to 2015 for Kutsaga area in Harare was used for the study. Seasonal weather data were used as input data to the first model to predict the ETo. The output ETO and effective rainfall data together with the crop factor (Kc), yield reduction factor (Ky), root zone depth (RzD) and root zone moisture (RzM)were used as input data for the second network to compute % yield reduction. Data for maize for the 2012-13 growing season was used for training the network and validating the estimated ETO and % yield reduction. The estimated ETO compared very well with the calculated values with R2 values of above 0.84. The estimated yield reduction % indicated even high accuracies with R2 values of above 0.91. The 2014-2015 growing season resulted in crop loss due to mid-season dry spells and the model predicted a 100% crop loss which means the farmer had to be compensated for the value equivalent to cost of inputs. The model has got potential to be used by insurance companies using weather based data and, with mobile banking transaction costs can be reduced.Climate change and climate variability and financial institutions’ unwillingness to give loans have resulted in many farmers losing confidence in dry land agriculture.

Cystic parotid lymphangiomas are benign vascular tumors that rarely appear in adults; they are usually detected in the first two years of life. Their appearance is due to an abnormal development of the lymphatic system during embryogenesis. Herein we report on two cases of intra-parotid cystic lymphangioma that occurred in teen age. A six year girl and a young girl of 13 years age were admitted in our unit because of an indolent and renitent isolated mass occupying the right parotid region. The diagnostic of an intra-parotid cystic lymphangioma was clinically advocated on echographic and CT imaging findings and then definitely proven after histopathologic studies of the ablation fragments. A total parotidectomy was made, removing the entire tumor. The parotid localization of cystic lymphangioma makes their surgical management difficult because of the development of lymphangioma between the branches of the facial nerve. The question of the benefit / risk ratio makes the therapeutic decision more complex because the aggressiveness of the radical tumor resection encounters a benign tumoral origin. It opposes two fundamental principles, first that of being radical on the tumor which is very recurrent and on the principle of remaining functional while preserving the function of the facial nerve.

Organizations came to the realization that it is not economically feasible to maintain the increasing maintenance costs of maintaining data centers with large floor space. One of the main concerns associated with Cloud Computing is the security of the service is that sensitive and important data is no longer only under the control of the data owner as the service provider also has access to that data. In terms of the methodological approach used by this thesis, this thesis will utilize the use of the qualitative method in answering the research questions posed by this thesis. The systematic literature review has shown that there are novel and innovative ways for organizations to mitigate the inherent risks associated with the use of cloud computing.

In order to better understand the zootechnical and economic characteristics of piglet farming, a diagnostic study was conducted from October to December 2019, three months with 30 pig farmers, in the form of cross-sectional and retrospective surveys in the three municipalities of the town of Kindu in the Democratic Republic of Congo. The results showed that pig farming was practiced by both married and educated men and women. They were mainly zimba, Kusu and Nande and associated livestock with agriculture, private activity or trade. They operated in two different livestock systems (traditional and semi-intensive), with a clear predominance of the traditional system (85.5% of farms). The latter was characterized by semi-intensive hog barns (51.1%), where local-bred pigs were mostly reared (90.4% of farms). The average herd size was 19.2 - 20.1 pigs. In 97% of cases, farmers fed the animals from kitchen waste and agricultural and agro-industrial by-products. The average breeding age was 7.6 -1.8 months and the average litter size was 7.4 - 2.2 piglets. This livestock subsector has real potential for poverty reduction because it generates net incomes on average of $40 per piglet, depending on the system. Nevertheless, the lack of training of herders, inadequate pig habitats, food and health constraints remain the main factors hindering the development of pig farming in this city. It would be useful to find alternative ways to improve the habitat conditions, feeding and health monitoring of pigs, accompanied by better organisation and capacity building for producers and other players in the hog sector.
