Bio-oxidation is the process of oxidation of metal sulfide using variety of microorganisms for leaching the metal. The aim of the present study was to assess the capacity of Acidithiobacillus ferrooxidans, on the bioleaching of lead from galena concentrate. While the process carried out under the sulfur concentration about 6%, the results showed that the maximum of 79.8% Pb was leached from the galena.

Secondary sexual organ chela of Barytelphusa cunicularis, a freshwater crab was measured in females and males collected random at field from backwaters of Jayakwadi Dam. Segmental growth of major and minor chela was analyzed among sexes. In male all the segments in major and minor chela showed positive allometric growth while in female, merus and propodus only showed positive allometric growth. Analysis of covariance (ANCOVA) of growth of major and minor chelae segments indicated that there was a significant difference in growth pattern between major and minor chela in males whereas in females the growth constants of major and minor chela segments did not differ significantly however, intercepts differ significantly.

Success is a disputed concept which is difficult to exactly define and quote. This study is related to Software Engineering field in which success factors and perception of key stakeholders (i.e. top management, core team and clients etc.) about software project success is tried to identify. Study postulates that there are so many dimensions which are behind of a successful software project. Success has different meanings and varies according projects to projects in Software Engineering industry. It is due to conflict in determination and selection of success factors among stakeholders. Software project stakeholders may differ based on their organizational culture and related goals, current market structure and their customized needs satisfaction (as a client or end user) from intended use of software. Qualitative technique has been applied by using thematic analysis on articles between the time frame of 1991-2010 with major three keywords of “software project success”, “project success” and “perception of stakeholders”. Study provides better understanding why there is a divergent view of success which stakeholders of a software project perceives and must need to know.

The preliminary survey of marine molluscs at 5 coasts of Shreewardhan namely Shreewardhan coast, Shekhadi coast, Dive Agar coast, Sarva coast and Harihareshwar coast were carried out. The occurrence of 65 species belonging to 52 genera, 35 families, 8 orders and 3 classes was noted. The Class- Gastropoda was diverse and represented by 3 orders, 24 families, 32 genera and 42 species. Class- Scaphopoda was represented by single order, family, genus and species whereas Class- Bivalvia was represented by 4orders, 10 families, 19 genera and 22 species of molluscs. Among these 65% of the species are gastropods, 34% are bivalvia and only 1% is Scaphopoda were noted. The present survey indicates that Sarva coast and Shekhadi coast are diversity rich followed by Shreewardhan coast, Harihareshwar coast and Dive Agar coast as far as molluscan diversity is concerned.

This study was carried out to examine survey responses across various levels of response predictors in some selected communities in oyo town, Oyo State, Nigeria. The design for this study was a two-stage stratified random sampling scheme. A Sample of 750 households was randomly selected in fifteen Enumeration Areas in Oyo town. The data were collected by interviewer-administered questionnaire and predictors of response were extracted for the verification of response rates at various levels of these predictors. Out of the 750 respondents that were interviewed in each of the five waves, 545, 615, 610, 615, 605 responded to survey questions respectively. The maximum number of visits considered for this research work is five per wave and after the fifth visits, respondents were regarded as non response. The response rates from the following predictors:- Females, those that were living with their spouse, those that were interviewed with English language, respondents at the middle age (50-79 years), those that are familiar with the interviewer and tenants were observed to be high. Also, the response rates increases from first visit to the fourth visits and at the fifth visit, it declined. We also observed that the more the number of years a respondent has spent in his/her community, the more they response to survey questions.

This paper analyzes sustainability and efficiency of organizations committed to the exploitation’ activities of tule Thypha spp at the Zapotlán’s Lake taking into consideration the socioeconomic and environmental impact in the municipalities of Gómez Farías and Zapotlán el Grande. The initial hypothesis departs from the consideration of the scarce social capital of organizations that limits development’s sustainability. The research method employed is the ethnographic complemented with field work supported by informal interviews, documental and bibliographic research. The hypothesis of this research is proved empirically and confirms similar findings by the research conducted on the mainstream theory of social capital and its implications on economic development. The outcomes of the application demonstrate that the drama of economic efficiency and sustainable development of micro-business is tied to constrain of social capital. This finding has implications for the design and implementation of economic and social policies oriented towards the improvement of economic growth and sustainable development.

From the investigations carried out on the Noctuidae during 2009-2011 in the Nilgiri Biosphere of Tamilnadu, six species of the genus Hypocala were studied. Among them, H. violacea Guenee was reported for the first time from the Nilgiri. Photographic illustrations of the male and female genitalia of all the known species of this moth are presented.

This paper reviews teaching strategies that secondary school (SL) teachers generally used for teaching of Pakistan Studies. Data for the study was collected from SL teachers through a questionnaire. Findings report that SL teachers consider memorisation of taught concepts as the main objective of teaching of Pakistan studies. Teachers perceive that oral lectures cannot develop in students’ desired traits of a citizenship and social values. Lecture strategy was found main strategy for teaching of Pakistan studies at SL. Inquiry or project strategies are usually not used for teaching of Pakistan studies, teachers generally do not plan lesson, they do not use maps or other aids for teaching of content about location, etc. Due to non availability of teaching aids in secondary schools. Pakistan studies may be taught through projects relating to students’ real life. Use of audio visual aids can make learning of Pakistan studies interesting for students. Resources like audio visual aids relating to the content of Pakistan studies for SL may be provided in schools.

The purpose of the given paper is to evaluate American English File (hereafter AEF) series (1st ed.). In so doing, to achieve the very purpose, Daoud and Celce-Murica’s 1979 attitude questionnaire was administrated to 50 EFL learners and 20 teachers in a popular language center, located in Bandare –e Anzali, Iran. The questionnaire aimed to elicit the agreement or disagreement of both learners and teachers on a Likert-scale. Based on the findings, it could be concluded that teachers had higher rating in comparison to the students for all the items. In general, there were significant differences between teachers and students in their attitude towards the textbook. Through this investigation, it is hoped that curriculum developers, before selecting a new material, make sure that it is able to meet both the students and the teachers’ need.

The rate of increase in construction site accident is very large which readily indicate the need to examine and overhaul the existing safety practices deployed in building construction sites. In order to improve the overall safety performance, there is ample need to investigate the root causes of accidents; results of which could be utilized in formulating more conducive working conditions and environments to avert accident. The following were conducted: review of literatures, archives of reported accidents cases kept by the Construction Industry Development Board (CIDB). Also social surveys exercise using structured questionnaire forms were implemented to obtain relevant data from respondents who are mainly contractors, developers and consultant within Imo State, Nigeria. The finding reveals that accident result from critical factors such as unsafe method, human element, unsafe equipment, job site conditions, management and unique nature of the industry. After due analysis the main causes of accident were attributable to workers’ negligence, failure of workers to obey work procedures and safety principles; operating equipment without safety devices; poor site management; harsh work operation work at high elevation; low knowledge and skill level of workers; failure to use personal protective equipment and poor workers attitudes about safety. In general, lack of adherence to safety requirements which has led to increase exposure of workmen and the general public to risk situations on construction resulting in a high rate of incidence of accidents.
