The environmental persistence of organotin compounds
The wide application of organotin compounds have caused considerable amounts of these compounds to enter the different ecosystems. Organotins have been of environmental concerns due to their direct introduction into the environment, bioaccumulation, and toxicities even to non-target organisms both aquatic and terrestrial. They are notable sources of pollution and may be of ecotoxicological effects on the various ecosystems. It is not only the particular organisms that may be affected but the whole ecosystems. They are very persistent and bioavailable to biota even after a long time. The persistence of organotins in polluted ecosystem is a function of adsorption and degradation processes. Hence, this review which aim at providing an overview of the environmental persistence of organotin compounds.

The performance of small medium enterprises (SME’S) operated by women and men in the non agriculture role enterprise in nandi county, Kenya
Entrepreneurship development is increasingly becoming important in economic growth in many countries. The majority of workers in the developing World cluster in small and micro enterprises in the private sectors. They may be on account workers in services or employees in small and medium-sized firms in manufacturing. Entrepreneurship and investment influences the rate and linkages, which develop in an economy, the labor demanded and the human capital investment required meeting these labor demands. Rapid growth can contribute to poverty reduction. Although there are variations across countries, social norms strongly influence men’s and women’s work and working environments. Some tasks and jobs are considered more appropriate for men or women and covert screening filters out applicants who defy these norms. These gender norms frequently underpin sex-segmented labor markets typically confine women workers to low-wage, low productivity employment and can limit the responsiveness of labor to new demands for high skilled workers. Sluggish labor markets can impede adjustment, distort human capital investment and inhibit a firm’s ability to switch to new activities and compete in a dynamics and globalizing market. Development occurs within an institutional and economics environment that is similarly shaped by customers, social norms, implicit and explicit codes and conduct. The study sought to establish the impact of gender on micro-enterprises performance. The main objective was to establish the differences in the constraint facing female and male owned micro-enterprises respectively in Nandi County in Kenya. Data from a survey of 180 micro-enterprises were used in the modified ordinary least square (OLS).

The relationship between economic status, level of education, formality of context and the use of requests in young Iranian couples
This study focused on investigating the relationship between making requests on one hand, and economic status, level of education and formality of context on the other. It examined the differences in the realization of requests in one area of Iran, i.e. Shahrekord, to account for pragmatic variations based on these three variables. To this end, sixty young couples based on their education and economic status were selected and surveyed in six different situations: 1) indoors, alone; 2) indoors, close family gatherings; 3) indoors, formal gatherings; 4) outdoors, with their relatives; 5) outdoors, being with a stranger; 6) outdoors, formal situations. A discourse completion test (DCT) was used as an elicitation device and a Chi-square was run to analyze the data. The results showed the preference order for the type of request used as direct, conventional indirect and non-conventional indirect. It was also found that as the degree of formality of context increases, the use of mitigation devices tends to increase as well.

The Relationship between Intermediate EFL Students’ Oral Production and their Lexical Knowledge and Self-Efficacy
Oral performance in general plays a significant part in any academic field and it is a flexible tool that can be used to meet a variety of goals (Diamond, 1999; Graham, 2006). This study aimed to illuminate and investigate one psychological and crucial factor influencing the oral performance: Self-efficacy (SE). Lexical knowledge (LK) also plays a significant role in oral performances. An attempt was made to assess the relationship among self-efficacy, lexical knowledge, and oral performance. In so doing, after homogenizing the students as Intermediate ones via a placement test, a standard questionnaire of SE (Owen&Froman, 1988) was administered to intermediate students. In addition a lexical knowledge test was taken. Afterwards, the researcher asked the subjects to deliver a speech on a general topic. Based on the results, the subjects were divided into four groups: 1) High SE, High LK, 2) High SE, Low LK, 3) Low SE, High LK, and 4) Low SE, Low LK. The data collected as well as the scores given to their oral performances were analyzed through SPSS (21.00). Results indicated that there were statistically significant differences between the two groups of High self-efficacy, high lexical knowledge and Low self efficacy, low lexical knowledge. The former group outperformed the latter one. The outcomes of this study can have benefits for both foreign language teachers and learners. They both can attain better results by focusing more on the psychological factor of self-efficacy and linguistic factor of lexical knowledge in their roles. The findings of the present study demonstrated that more concentration ought to be placed on this psychological factor as well as lexical knowledge of the learners in order to enhance their oral performances.

Upgrading of Egyptian Newly Discovered Phosphate Ore of Nile Valley
Phosphate ores are used for phosphoric acid, fertilizers and animal feed production. In Egypt phosphate ore reserves are present in three main localities namely; Nile valley, new valley in western desert, and the eastern desert along the red sea coast. Currently, newly discovered phosphate ores are being mined from Nile valley areas mainly for exportation and partially for local production of fertilizers. However, in exporting such ores, the mining companies export only the coarse fractions of the run of mine ores of high grade (over 30 % P2O5) while the fine fractions of low grade (~ 18-22 % P2O5 content), for the time being, are rejected. This is because such fine fractions contain different gangue minerals such as calcite and silica. This paper aims at studying the amenability of upgrading such rejected fine fractions of Nile valley areas through application of froth flotation process. Such flotation technique is investigated to separate the associated gangues (silica and calcite) from the fine fractions of phosphate ores. The different operating conditions affecting on the efficiency of separation of phosphate mineral from its associated gangues are studied. These parameters, among others, are collector dosage, depressant dose, and pH. At the optimum conditions of flotation, a phospho-concentrate of about P2O5 of 29.5 % and 7.6 % A.I. is obtained from a feed sample containing about 21.13 % P2O5 and 19 % A.I.

What Do Donors Want of NGOs? Some Empirical Evidences from Indian NGOs
This article is based on a Ph.D. research study of the voluntary sector in India, of which non-governmental organizations are a part. The perceptions, assessment and recommendations of donors and experts on various aspects of NGO functioning were examined in depth as one of the components of the research, in the backdrop of social marketing objectives. The study covered the most important aspect of the application of marketing principles to socio-economic development, besides identifying important issues governing the operating effectiveness of NGOs and the traits and qualities that make them eligible for donor support on a sustained basis. .The results suggest that in the Indian context, level of funding significantly influences performance of NGOs. While the program component of social marketing effectiveness had a significant relationship with level of expenditure, there was, however, no relationship between level of expenditure and social marketing effectiveness as a whole. A significant conclusion of the paper is that NGOs should project a more positive image of their performance and credibility to donors. The paper also suggests that systematic outcome measurement is critical to assess NGO performance.

A Case Report of Scrub Typhus patient reported from SBS Nagar, Punjab, 2015
Scrub typhus is an acute, febrile, infectious illness caused by Orientia tsutsugamushi. Humans are accidental hosts in this zoonotic disease1. Scrub typhus presents as fever with little to distinguish it clinically from co-endemic diseases like typhoid, leptospirosis, and dengue. The presence of an eschar supports the diagnosis but is variably present.2 Scrub typhus is prevalent in many parts of India but specific data are not available3. There have been outbreaks in areas located in the sub-Himalayan belt, from Jammu to Nagaland. There were reports of scrub typhus outbreaks in Himachal Pradesh, Sikkim and Darjeeling during 2003-2004 and 2007. Scrub typhus is a re-emerging infectious disease in India4.

A new approach to evaluate higher order differential equations by differential transformation method and homotopy perturbation method using boundary value problems
We have to make comparison among differential transformation method (DTM) and Homotopy Perturbation Method (HPM). We provide two examples in order to compare our results and find exact solutions also. The numerical examples show that the DTM is a good method compared to the HPM since it is effective, uses less time in computation, easy to implement and achieve high accuracy. From the numerical results, DTM is suitable to apply for nonlinear problems. Numerical results show that DTM is a promising and powerful tool for solving the higher-order boundary value problems as compared to HPM.
