In spite of its usefulness, initiation rituals in Lugurus have been blamed to impede girls' education. In a research conducted in Morogoro rural district between April and June 2011 with the aim of investigating the effects of initiation rituals to primary and secondary school girls, a sample of 74 respondents were involved of which 46 were girls from Mkambarani ward and from both primary and secondary schools. From the research it was found out that girls attend initiation ceremonies as early as they reach puberty be eleven or twelve years. Further it was established that the girls who attend the ceremonies encounter mistreatments, abuse and sometimes they miss their precious school time. Complementing that it was learnt that after the ceremonies, girls change their behavior and thus some of them feel they cannot cope with formal education. As a result of the change of behavior the girls reported dropping out of school to pursue other womanly responsibilities of getting married and having families.
Laboratory study was conducted to investigate allelopathic effects of seed aqueous extract of Pennisetum glaucum on seedling growth of three cereals; Avena sativa, Triticum durum and Hordeum vulgare Different levels of P. glaucum seed aqueous extracts concentrations (0%, 2%, 4%, 8% and 10%) were used to test its effect on the studied species. Results revealed significant allelopathic effects of seed aqueous extract of P. glaucum on radicle, coleoptile and total plant lengths. However, it was found that Avena sativa was the most susceptible and Triticum durum was the less sensitive on seed aqueous extract of Pennisetum glaucum.
One of the major flaws of the Nigerian industrialization is the over emphasis on temporal growth with little or no emphasis on safety of workers in spite of the existence of Factories Act. This study examined the level of compliance to occupational health and safety standard among small scale industries in Ondo state. Data were collected from industrialists, workers and government's supervisory body through three different set of questionnaires. Data collected were analyzed using simple tables and bar graphs. The grand mean weighted values were compared with the mean weighted value in order to isolate the most important responses. The study discovered a very low level of compliance among small scale industries in the study area Out of 250 enterprises sampled, 62% (155) did not provide safety kits to their employees, 43% (108) did not have adequate ventilation, and 54% (135) did not have sanitary conveniences, while 35% (88) had no recreational facilities at all. In spite of this however wood based enterprises were identified to have the most compliance, although the compliance is only slightly above average (score of 37 out of a total of 60). Regional analysis of the pattern of compliance revealed that out of the 55 industries that had some acceptable level of compliance (which is only22 % of the entire industries sampled), Ondo North region was ahead of the other two regions Ondo North and Ondo South with 62%(34) of industries while others varied from 16%(9) to 22%(12). Reasons for low compliance were sought from proprietors workers and officials in the state ministry of industries which is the supervising body. Reasons given varied from lack of finance to ensure compliance, the belief that OHS was only meant for large scale industries, Proprietors lukewarm attitude to OHS, and fraudulent practices by supervisors.
Religious institutions may be agents of advocacy, funding, innovations, empowerment, social movements and service delivery. This paper attempts to investigate the impact of religious and educational institutions in the livelihoods of the pastoral Maasai. The study was conducted in Monduli District. A cross-sectional design was adopted whereby structured questionnaire was administered to collect primary data. Secondary data were collected from District, religious and educational institutions' offices. A sample of 140 respondents was drawn from the population. The Statistical Package for Social Sciences software was employed for data analysis. From the findings it was observed that religious and educational institutions play their roles in changing the livelihood of the pastoralists by establishing and supervising various socio-economic activities aiming at poverty reduction. These projects include formal education and health services, water supply, food security and income generating activities. Participatory approach is adopted for the sustainable development projects. The opinions of beneficiaries were sought and it was found that religious and educational institutions had brought positive changes on the livelihoods strategies and systems of the pastoralists. It is recommended that religious and educational institutions and other development activists should introduce similar interventions for other tribal people particularly the Barbaig, Hadzabe and Sandawe. Their livelihood patterns need to be changed because of the changing environment.
This article is devoted to the influence of short cotton fibers and trash on the yarn quality parameters, as well as the yield of yarn and waste of cotton fiber. Carding process at a spinning mill is the last step of removing trash and defects such as neps, peel, seed count neps. Flaws found in the card sliver directly affect the number of defects in the yarn. These defects can not be detected by weight testing and roving sliver. In order to determine short fibers in the card sliver modern fiber measuring instrument USTER AFIS PRO-2 is used. As an object three different lots of cotton fiber of sort 1 in 4 types of selection C-6524 were taken from three different cotton cleaning factories. Studies have shown that removal of neps, short fibers and trash are not dependent on each other. As well as analysis of the results showed that the yarn produced from cotton fibers in cotton cleaning factory-1 meets 5% level according to international standard USTER tester. In this factory cotton fiber have been reported with short fiber content of about 5.6%, and the number of neps 227 units per gram of fiber. Second and Third cotton factories' fibers comprising a short fiber content of 8.7% and 10.3%, and the number of neps are 269 and 280 units respectively. Studies showed that the content amount of short fibers is not changed, and in the process of carding even increases so that it requires careful research.
The present study therefore, deals the germination and growth status of Caesalpinia bonduc endangered medicinal plant in Meerut district U.P. C. bonduc of family Fabaceae is a moderately size deciduous shrub species, growing wild throughout the deciduous forest of India. Caesalpinia bonduc is highly valued plant species for the human beings and environment management. The plant parts like barks, leaves, root and leaves widely used for medicinally purposes. The plant species is distributed few parts of India but now it is threatened species in many areas in the country. The species does not found in Meerut areas.

It is concluded that the aim of the present study is to spread awareness towards the conservation and establishment of the endangered medicinal plant Caesalpinia bonduc in those areas where the plant species is now does not found.
In this article, we focus our work on the modeling of genetic risk factors on ischemic strokes occurred. To do this, logistic regression was widespread in our study. We proceeded in two stages: the first, we modeled the probability of the occurrence of ischemic stroke in an individual (i) based on genetic risk factors. Our sample consisted of 330 individuals aged at least 40 years, divided into 165 patients who had an ischemic stroke and 165 controls. We applied the Wald test for all variables in the model one by one and we concluded to Reject H0, since the coefficients of our variables are not all zero. In a second step, we studied the effects of these variables on the risk factors and then the effect of variables on Ischemic stroke to present the model equation. We set a prediction threshold after specification test, that allows us to ensure the quality of the fit of the model and its degree of prediction, the proportion of people who have ischemic stroke is (50%). The results showed that 128 of 156 people with Ischemic stroke allowed a positive predictive value of 82%. We conclude that the prediction rate and the success rate of our model is 80.30 %, the results obtained with the «XLSTAT» software show a very good model with (sensitivity 78% and specificity 83%).
In this research we propose a cluster for handling the existing processing problems in distributed environments. The volume of data transmitted through online service provider facility is already measured in terabytes. A single customer support outlet sends approximately 2 GB data in one day. Normal digital computers face instances like resources, cost and processing time for the processing of such large amount of data. Here we propose Cluster computing as solution of processing speed problem in processing huge amount of data transmitted. Experiment results shows that processing speed is directly proportional to computational power.

Robots are being used across the various domains of manufacturing, services, healthcare/medical, defense, and space. Robotics was initially introduced for dirty, dull, and dangerous tasks. Today, robotics is used in a much wider set of applications, and a key factor is to empower people in their daily lives across work, leisure, and domestic tasks.
Process with high dimensional data is enormous issue in data mining and machine learning applications. Feature selection is the mode of recognize the good number of features that produce well-suited outcome as the unique entire set of features. Feature selection process constructs a pathway to reduce the dimensionality and time complexity and also improve the accuracy level of classifier. In this paper, we use an alternative approach, called affinity propagation algorithm for effective and efficient feature selection and clustering process. The endeavor is to improve the performance in terms accuracy and time complexity.
The research paper discusses a user activity based building automation system for real time monitoring and control for a standard one-bedroom unit. Standard buildings designed and built in Nigeria are without any form of automation and with emerging technologies that support automation of certain sections/processes in buildings the intelligent building paradigm can be a realizable objective. This paper thus proposes a microcontroller based design interfaced with appropriate sensors, actuators and voice recognition abilities to develop a building automation system (BAS) whose control action is based on human activity analysis/ human presence detection. The developed system when implemented would offer the advantage of real-time occupancy information for control of lighting and other electronic circuitry so as to save a significant amount of the electrical energy.
