After 1980, as the supply of conventional energy has not been able to follow the tremendous increase of the production demand in rural areas of the world, a renewed interest for the application of solar and wind energy has shown in many places. Therefore, the researchers and engineers began to pay more attention to wind and solar energy utilisation in rural areas. Because the wind energy resource in many rural areas is sufficient for attractive application of wind pumps, and as fuel is insufficient, the wind pumps will be spread on a rather large-scale in the near future. Wind is a form of renewable energy, which is always in a non-steady state due to the wide temporal and spatial variations of wind velocity. The need for the provision of new data stations in order to enable a complete and reliable assessment of the overall wind power potential of the country is to be identified and specific locations suggested. This article presents the background and ideas of the development of the concept as well as the main results and experience gained during ongoing projects up to now. In the world, various designs of wind machines for water pumping have been developed and some designs are presently manufactured commercially. Results suggest that wind power would be more profitably used for local and small-scale applications especially for remote rural areas. It is concluded that many parts of the world is enjoyed with abundant wind and solar energy resources.","PeriodicalId":21707,"journal":{"name":"Scientific Journal of Review","volume":"88 1","pages":"271-288"},"PeriodicalIF":0.0,"publicationDate":"2016-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83440951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These constituents play an important role in immunity and health of the newborn calves, as they are born with weak immunity and acquire their immunity after birth within three weeks continuously after being fed the colostrums. Feeding colostrums immediately after birth is found to protect the calves from the pathological factors which are around them at birth and at the beginning of breath. The synthesis of the colostrum takes place at the end of pregnancy during the dry period after increasing the hormones receptors on the epithelial cells in the udder. Colostrum production continues after birth for five days and it is the source of immunoglobulin G (IgG) and a part of IgA, IgM, in colostrums is the blood, whereas the plasma of the epithelial cells in udder synthesizes 50% of IgA and IgM. IgG forms the greatest part in colostrum approximately 85-90% and the remaining parts are IgM at rate 7% and IgA at rate 5%. Controlling udder within the dry period is basic to prevent inflammation especially subclinical mastitis, because it will lead to retard the colostrum quantity after birth and decrease its concentration of Ig especially IgG. It is important to determine immunoglobulin level produced after birth using different methods especially the field ones, which are simple and available. These methods will help to categorize and freeze the good quality surplus colostrum to feed the newborn of low quality colostrum producing cows.","PeriodicalId":21707,"journal":{"name":"Scientific Journal of Review","volume":"9 9 1","pages":"242-249"},"PeriodicalIF":0.0,"publicationDate":"2015-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88702602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The preceding review explores the opportunities and constraints that are associated with increasing the development impact of agricultural research in enhancing food and nutrition security in Sub Saharan Africa. The engendered agricultural research approach in promoting food production and security is examined. There is an attempt to describe the impact of gender-sensitive agricultural research on food production and its implication for food and nutrition security. The influence of policy environment, inclusion of micro-livestock and insects farming in the mainstream agriculture production and agricultural research priorities in increasing the development impact of agricultural research are highlighted. It is also suggested that incorporating indigenous knowledge as the basis of agricultural research may promote increasing development impact of agricultural research in the region. Climate smart agricultural research should become increasingly important such that it influences food production and achieve the primary objective of achieving food and nutrition security. Sub Saharan Africa is endowed with potential good agricultural space which can be put in good use through increasing the development impact of agricultural research in a manner that the ultimate goal of self food and nutrition sustenance is attained. The review concludes that in the planning and implementation of agricultural research to enhance food and nutrition security, gender sensitive agricultural policies should be put in place such that women become the focal point of food production in Sub Saharan Africa. The sustainable development goals aimed at achieving food security and improved nutrition and promoting sustainable agriculture can be only realized through increasing the development impact of agricultural research in Sub Saharan Africa.","PeriodicalId":21707,"journal":{"name":"Scientific Journal of Review","volume":"123 1","pages":"232-241"},"PeriodicalIF":0.0,"publicationDate":"2015-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76662340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It puts under investigation literary pieces of language and yields an understanding of the components has in its very texture. The aim of this article is to provide insights about the field of ‘narratology’ and its associated subject of study ‘narrative’. It also tries to sketch the main issues concerning these two concepts. For this, the present review is presented in two major sections, each with related discussions about narratology and narrative. The first major part, narratology, will be presented in three sections: the first section, deals with the definitions and origins of narratology. The definitions are inspected and the researchers show how they go from general (encompassing all which is narrated) to more specific (encompassing literary narratives told by a narrator) ones. The second section, focuses on the two phases of narratology which are classical and post-classical ones in which narratology changed its orientations and scope. The last section is devoted to some of the elements and components of which narratology is made up, such as narration, focolization, narrative situation, action, story analysis, tellability, tense, time, and narrative modes which will be elaborated on in more details. The second major part, narrative, will be presented in four sections: first the concept will be defined and introduced. Then the features which make a narrative will be specified and elaborated on. In the third section, some of the elements of narratives like story, discourse, events, and existents are stressed. In the last section, it is elucidated that narrative is not just a written printed genre, rather it consists of performed genres such as plays, films, and operas.","PeriodicalId":21707,"journal":{"name":"Scientific Journal of Review","volume":"7 1","pages":"182-192"},"PeriodicalIF":0.0,"publicationDate":"2015-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77332520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each node is responsible for gathering environment data and sending it to BS in order for received data to be analyzed. One of the main problems of this kind of network is the little primary energy of nodes and the little space of node memories. Each time data is sensed, node energy is reduced. Continuation of this situation results in the reduction of network lifetime or death. Suitable methods are presented for data transfer from nodes to BS. These methods have been able to optimize energy consumption in comparison with similar previous methods. One of the methods of acceptable optimization of energy consumption and network lifetime is the use of genetic algorithm in the network process of routing. Each method makes to using of different parameters that these parameters have created strengths and weaknesses. In this research, we present useful solutions for the reduction of energy consumption in network by the use of genetic algorithm. The main idea is to consider the methods proposed in recent years. The simulation results of creditable essays have been used to show the strong and weak parts of presented methods. Then, optimization solutions have been proposed by the use of simulation results and the weaknesses of existing methods.","PeriodicalId":21707,"journal":{"name":"Scientific Journal of Review","volume":"4 1","pages":"165-181"},"PeriodicalIF":0.0,"publicationDate":"2015-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85244934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
