Here, a equilateral triangular shaped circular feed network is designed. This circular feed network can radiate in eight different directions. This radiation is depending on four inputs ports which are excited. It can cover wide area within upper hemisphere. This antenna is designed in such a way that it is useful for any applicable GHz ISM band frequency and utilizes a suspended FR4 substrate. For this antenna we used positive microstrip elements, so that it will make easy to manufacture.

The furthermost impact of the climate change would be displacement of people, leading mass migration at a large scale. The affected communities would be largely from climate vulnerable island nations and also from developing countries which will not have the infrastructure to cope with the climate change induced natural disasters. The main issue here would be the cross-border migration leading to refugee status claims. But the present international refugee law framework governed by the Refugee Convention, 1951 is in no way equipped in dealing with climate refugees. This clearly calls for international co-operation and consensus building for dealing with the climate refugees as a part of the climate change adaptation mechanism. An effective and binding provision in the climate change agreements for tackling climate change induced migration through co-operation is crucial. This paper points out the lacunae in the present international refugee law framework and discusses regarding mitigating this gap and provides pointers regarding the way forward.

In this research, optimization of electromagnetic shielding tester process parameters for conducting textile composite materials through Taguchi design and ANOVA has been reported. The electromagnetic shielding tester process parameters were selected to optimize the EMSE. The effect of the size of the test Conductive Textile Material Composite sample on EMSE, effect of distance between Conductive Textile Material Composite sample and transmitting antenna on EMSE, effect of distance between the Conductive Textile Material Composite sample and receiving antenna on EMSE, and effect of RH% on EMSE were analyzed and optimized by Taguchi design and ANOVA. It was observed that the electromagnetic shielding effectiveness of conductive textile Composite materials were dominantly influenced by Conductive Textile Material Composite sample size and significantly influenced by distance between Conductive Textile Material Composite sample and transmitting antenna.

Organotin compounds have attracted global attention due to their extensive use for agricultural, industrial, medicinal, and domestic applications. These applications have made them enter the environment. This has caused environmental concerns due to the proven toxicological relevance of the compounds. Their toxic effects result in extensive damage to non-target organisms at ultratrace concentration levels (ppt) and accumulation in sediments and biota. This leads to the legislative restriction place on the uses of some of these compounds. Despite the legislative restriction, their environmental pollutions continue. Hence, this review which is aimed at providing an overview of the application of organotin compounds and their environmental toxicities.

Osteoid osteoma is a benign osseous tumor of unknown origin, which affects preferentially the long bones. The localization in the phalanx is unusual and difficult to diagnose. We present a case of a twenty-year-old student, presenting with a painful swelling of the first phalanx of the right second finger of six months duration, not responding to anti-inflammatory drugs. The lesion was excised, and the histology confirmed the diagnosis of osteoid osteoma. Through our observation and after a review of the literature, we analyze the clinical and paraclinical appearance of this uncommon localization, the differential diagnosis, and finally the therapeutic possibilities.

A study on rotifers was conducted to count percentage prevalence from Upper Dudhana dam of Jalna district, Maharashtra, India. Rotifera is major group from zooplankton having divers planktonic forms and they shows variation in occurrence amongst them. Samples were collected fortnightly interval for a period of one year from February 2014 to January 2015 and percentage prevalence was counted. Result indicated that the highest percentage prevalence was showed by Brachionus caudatus (87.5%) whereas lowest by Keratella vulga (20.83%) during the period of sampling. The authors concluded that Brachionus caudatus was persistently present in all the seasons of sampling period. The above study gives information of the status of rotifers and providing new insights into its ecology.

The balance of physical, emotional, spiritual and intellectual student can be generated from both the academic and non-academic education. Student involvement in co-curricular activities can help to shape the soft skills of the students as the supply of self-promotion in the workplace. Student involvement, directly or indirectly can improve their soft skills, especially problem-solving skills that have a low percentage of the graduates in the country. The researchers wanted to investigate the students' perceptions of involvement in co-curricular activities to enhance the development of soft skills.

This research examines the effects of personality characteristics of mothers on the level of socialization and desocialization of preschoolers. Survey prepared in accordance with the purpose has been applied to parents and teachers of three different nurseries in Atasehir, Istanbul. The data attained from the surveys have been evaluated with SPSS statistics program in computer environment. In determining the levels of the social adaptation and maladaptation of preschoolers and showing their mothers’ personality characteristics, average and standard deviation statistics were used, to determine the relations between mothers’ personal characteristics and the children’s state of social adaptation and maladaptationthe correlation analysis and in determining the effects of the personal characteristics on children’s state of social adaptation and maladaptation regression analysis were used. As the result of the research, it has been found out that the preschoolers are affected by their mothers’ personal traits of compatibleness and emotional disorder negatively. As the mothers’ level of showing their responsibility and emotional disorder personal traits increases, the children’s social maladaptation level decreases. Other personal characteristics do not affect the social adaptation and the maladaptation level of children.

The organizations are interacting with suppliers, customers and even competitors in order to achieve the customer satisfaction as well as the greater success and profitability in the new commercial environment. Supply chain management is the most important part of the company’s strategy to optimize the planning and implementation of the processes to respond to the market changes and it will not be possible without the efficient and effective internal process. Certainly, to ensure effectiveness of the integrated processes, they should be periodically evaluated by some indicators. Therefore, this study has discussed the effectiveness of supply chain management using the balanced scorecard methodology, to do which a goal programming model is presented to minimize sum of deviations. In this study, first, the indices affecting the four perspectives (financial, customer, internal process and learning and growth) of balanced scorecard in ISACO Corporation are identified. Then, the weight and prioritization of the indices affecting the four perspectives of balanced scorecard are calculated, and then, the distance of performance of each one of the perspectives of balanced scorecard from the goals of the studied company has been measured. In addition, the goal programming model is presented to evaluate the effectiveness of supply chain in order to minimize sum of absolute deviations using the goal programming model.
