Ptercarpus santalinus is an important endemic medicinal plant with high medicinal values that interfere with DNA extraction procedures and qualitative, quantitative agaros gel electrophoresis. An effective and low-cost protocol for isolating genomic DNA from the roots of Pterocarpus santilinus and Pimpinella tirupatiensis was described in this paper. It involved a modified CTAB method with distilled water pretreating samples. The A260/A280 absorbance ratio of extracted DNA was found to be free from polysaccharide, poly-phenols and tannins contaminants ranged from 2.2 to 2.8 within the high level of purity.

Nine specimens of the cestode parasites were recovered from the intestine of Clarias batrachus at Amravati, in the month of March, 1984. They were stained in Borax carmine, whole mount and histological slides of the worm were prepared for detail studies. The mature flattened specimens were long, cylindrical and measure 4.805 in length and 0.674-1.484 in breadth. Morphology and anatomy of the worm is fully discussed in this paper.

Since muscle is more dense than fat, athletes tend to have greater mass and BMI than similarly sized non-athletes. Comparing direct adiposity measures and BMI confirms that BMI is a biased proxy for adiposity for elite athletes. A similar bias should exist for non-elite athletes as well as fit individuals.This paper provides a methodology for indirectly estimating the size of the fitness bias in BMI using median physical activity performances. Approximately 30% of females and 33% of males are fit using this definition.Using data from 9 062 students, regressions suggest 3.1, 95% CI [0.9, 5.3], of a female’s BMI percentile of 85, and 3.6% of her weight, CI [1.6%, 5.6%], is due to being fit, but 5.6, CI [3.3, 7.9], of a male’s BMI percentile of 85, and 5.9% of his weight, CI [3.9%, 7.9%], is due to being fit. These increases in weight are smaller than, but consistent with, the bias of more than 20% for elite athletes.Strong performance on individual physical activities decreases BMI percentile and BMI, but doing well on multiple physical activities has the reverse effect. This provides evidence of a fitness bias. BMI report cards should include the caveat that BMI may overstate the adiposity status of fit children.

The paper refers to the use of project method by students who were attending the first, second and third grade of High School in Greece. We designed and realized a research in order to examine the improvement of students’ attitudes and views towards the subject of Arts using the project method. The subject of the project in the first grade of High School was “the traditional village of Lindos”, the subject of the project in the second grade was “the medieval city of Rhodes” and the subject of the project in the third grade was "the acropolis of Filerimos". All the areas under study were in Rhodes, Greece. Questionnaires were given to the students before and after the teaching interventions which was realized during the first quarter of the school year 2014-2015. The results showed that the use of project method vindicated the goals of the research and improved significantly the students' views and attitudes towards the subject of Arts.

Undergraduate students were instructed how to assess the health of 24 urban willow oak trees. Students received hands-on training using the Resistograph 400 on two sites: a depressional site and a well-drained site on the campus of Stephen F. Austin State University in an upper division Urban Forestry course. Students followed the instructed and prescribed method of drilling three holes at 120 degree intervals at 3.5 feet in height above ground in each oak tree. Tree condition data were recorded on paper strips and analyzed in laboratory for percent decay measured for each sample. The results were averaged for the three samples per tree and the percent of soundwood was determined. Resistograph data were then analyzed by the students using SAS ANOVA for the 24 trees within the two sites. Results indicted a significantly higher amount of decay on the depressional sites compared to the well-drained sites. Data collected using the standard CTLA tree health assessment method indicated willow oaks in depressional sites had a significantly lower condition rating based on six measured tree variables. This study demonstrated that incorporating intensive hands-on instruction within an undergraduate student’s education increases retention rates, enhances their educational experience, and produces a more well-rounded urban forester.

Integrating songs and stories in mathematics learning constitutes an important tool for cultivating mathematical literacy as well as one of the ways of overcoming learning difficulties. Learning mathematics is attributed greater importance if it integrates topics associated with children's environment. This paper makes use of one of Mother Goose songs for implementing a mathematical activity dealing with the issue of series and their graphic presentation.

Okoubaka aubrevillei is the largest parasitic plant known to man. It is a tropical tree species distributed within West and Central Africa. Concerns were drawn to the tree because of its rarity, disjunct distribution in all its native range, paucity of published scientific information and its hemi-parasitic potentials. This article gathered and synthesized all existing scientific information on the tree to provide a solid foundation for further research on the tree. This article provided detailed information on its name etymology, taxonomic history, and geographical distribution including new locations for the tree, ecological significance and behaviour within its range, supported with an updated map illustrating its distribution within West and Central Africa. The possible causes of its rarity in its range were identified and its hemi-parasitic behaviour was hypothesized. In addition, ethnobotanical uses of the tree, symbolism and dendrolatry, and its significance in modern medicine were extensively discussed. The paper concluded with highlights on prospects for immediate conservation, management and research focus areas for the tree species.

Tourism Industry by its nature in the World, it is the trait that cannot be separated from the social life of the communities as it is practised on their territorial lands that they depend for their socio-economic aspects. That strong relationship has caused rapid growth of tourism activities to developing countries and led to new national and international expectations for tourism as an agent of socio-economic development. The World GDP contributions from tourism by 2013 grew to 3.1% and contribute to 101 million jobs, and in Tanzania total contribution to GDP was 12.7% where by contributed 4.9% direct and total employment contribution were 11.2% and 3.8% direct of the total employment. In Ngorongoro Conservation Area with a population of about 87,851 residents from Maasai, Datoga and Hadzabe tourism contributed to 92% of the total economy of the area where by 8% was from other sources and 48% total community economy and 29.2% direct to people and 9.7% of total employment. The findings revealed that major relationship of the tourism and socio-economic based on economic activities contributions (livestock services), Social services (education, healthy, culture and life style), resources ownerships and infrastructure developments. The paper considered community survey of 120 local residents from 4 wards of the NCA, examines whether tourism has direct relationship to the Socio-economic aspects of the residents of the area and the levels of the contributions to their development. I found that regardless a claimed little contribution to their economy; many people appreciated the social and economic changes related to the tourism of the area.

B. senegalensis leaves and fruits are known to contain glucocapparin which hydrolysis by endogenous myrosinases lead to the release of methylisothiocyanate (MITC). This product is very active against insect stored products by fumigation. This paper reveals that MITC penetrate into seeds during treatment. Multiple Headspace Extraction coupled to GC (MHE-GC) method allowed to evaluate the level of MITC residues sequestrated by exposed seeds to B. senegalensis organs. Furthermore, tests conducted on germination capacity have been demonstrated that MITC doesn’t corrupt the germination capacity of grains.

There is no doubting the fact that eruption of violence in most tertiary institutions nowadays is as a result of dwindling social relationship and loss of cultural values. The unsatisfying consequence therefore, has really taken its toll on the overall development of the educational sector. This paper examines violence in tertiary institution and proffer solutions that will in no small measures reawaken cultural values.

The purpose of this research paper was to explore how HIV/AIDS manipulate nurses’ perception of their workload and pay in the era of HIV/AIDS in Gaborone and the surrounding areas of Botswana. The health care sector in Botswana is overwhelmed by HIV/AIDS, and this takes a toll on the nurses because they are the ones at the forefront in the fight against this demanding and risky illness at the workplace. The focus in this study was on the workload and pay in the era of HIV/AIDS. The general picture that emerges from the current study is that nurses are dissatisfied with their pay and to some extent the workload and this supports some of the earlier studies which reinforce their importance in the workplace. The study used both primary and secondary sources of information. For the purpose of this study convenience sampling was used. A questionnaire was used for data collection. The study adapted Index of Organizational Reactions (IOR). The findings of the current study will help the government to design strategies that will increase the level of job satisfaction among the nurses in the public health care sector of Botswana.
