Quantitative Structure Activity Relationship Analysis of Selected Chalcone Derivatives as Mycobacterium tuberculosis Inhibitors  [PDF]
Alisi Ikechukwu Ogadimma, Uzairu Adamu
Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1102432
Abstract: In order to gain further insights into the structural requirements for anti-tuberculosis activity by chalcone derivatives of 1,3-diphenylprop-2-ene-1-one, quantitative structure activity relationship (QSAR) was performed using genetic function approximation (GFA). Geometry optimization was achieved at the density functional theory (DFT) level using Becke’s three-parameter Lee-Yang- Parr hybrid functional (B3LYP) in combination with the 6-31G* basis set. Subsequently, quantum chemical and molecular descriptors were generated and divided into training and test sets by Kennard Stone algorithm. Internal and external validations as well as Y-randomization tests were employed in model validation. Five predictive models were generated by GFA. The generated models showed that constitutional indices, 2D autocorrelations and radial distribution function (RDF) descriptors were important contributors to anti-tuberculosis activity of 1,3-diphenylprop-2-ene-1-one derivatives. Based on validation results, model 4 was chosen as the best of the five models.
Re-Strategising for Effective Health and Safety Standards in Small and Medium-Sized Enterprises  [PDF]
Ikechukwu A. Diugwu
Open Journal of Safety Science and Technology (OJSST) , 2011, DOI: 10.4236/ojsst.2011.13013
Abstract: Poor health and safety record impact on the image/reputation and operational capabilities of businesses, especially those within the small and medium enterprise (SME) sector. Given the role of SMEs in the economy, this paper attempts to highlight the issue of poor health and safety performance of the SME sector and suggest a strategy for improving the level of performance. To this end, survey questionnaires were distributed to assess the overall awareness of people about health and safety issues, motivations and constraints, vis-a-viz supply chain improvement initiatives. Based on the findings (responses from questionnaires) and existing literature, the unique characteristics of the supply chain network makes it a suitable medium through which health and safety improvement in small and mediumsized enterprises can be realised. Additionally, the findings show that good health and safety management culture enhances image, lowers costs, and improves the overall competitiveness of organisations. To complement the efforts/desires of health and safety regulators, there is need to leverage on the relationships that exist in supply chains, shown in this exercise to have a major influence on the activities of organisations.
Character and Culture: Towards a Man of Character—The Relevance of Traditional Igbo Family Values  [PDF]
Paul Ikechukwu Ogugua
Open Journal of Philosophy (OJPP) , 2013, DOI: 10.4236/ojpp.2013.31A014

Character and culture describe man both as an active and a passive agent in life. It is by being fashioned by culture that man cultivates character and by the use of this character so acquired that he develops and upgrades his culture; for culture is dynamic, that is elastic; as such there is need for eternal vigilance on the part of man to see his culture evolve and become better at every point in time. This can come about either spontaneously or through an agency; it is the duty of an agency to act upon what is given, required to produce a good result, in our instance to act on Igbo-African family values. This entails a dialogue of man and his milieu, for character grows form a healthy and salutary agent, so knowledge of, belief in and application of values is indeed a precondition.

The efficacy of crude extracts of Senna alata in the improvement of vegetative and reproductive growth in Celosia aregentea was investigated. Fresh leaves of S. alata were blended with a homogenizer in 1 litre of distilled water. The resultant green paste was filtered under suction. Different concentrations (75%, 50%, 40%, 30%, 25%, 12%, 10%, and 5%) were prepared from the 100% crude extract. Seeds of C. argentea were presoaked in these different concentrations including a control (0%) and planted out after 24 hours. Results obtained showed that seedling height, leaf area, dry weight and leaf area ratio were promoted and enhanced by presoaking seeds in the extract. At the end of the experimental period (six weeks), seedling height in 75% and 100% treatments were 109 ± 16.12 cm and 117 ± 19.32 cm, leaf area 128 ± 17.91 cm2 and 125 ± 18.12 cm2, dry weight 7.48 kg and 7.0 kg respectively. Seedlings raised from seeds presoaked in water (control) however, flowered earlier (8 weeks) than the treatments (10 weeks in 75% and 100%). Presoaking seeds of C. argentea in crude extracts of S. alata before planting is recommended for optimum production of the leafy vegetable. The procedure is cheap and easily implementable by resource-poor farmers who are the main growers of C. argentea.

Synergism of Dance Theory and Practice: The Requisite for Dance Development in Nigeria  [PDF]
Christian Ikechukwu Nwaru
Art and Design Review (ADR) , 2014, DOI: 10.4236/adr.2014.24011
Abstract: In the history of dance development, organise systems of accepted knowledge as applied in variety of circumstances were used in explaining different set of phenomena that informed the action, operation or behaviour of dance and vis-à-vis. This paper traces the long aged dichotomy between the theorists and pragmatic dance practitioners in Nigeria. The researcher observes that this un- healthy division among the dance artists in Nigeria is delaying the progress of the already margi- nalised section of the performative art. He submits that for virile development of dance to take place in Nigeria, the balance application of the theory and practice of dance art is necessary.

Natural Resources (NR) , 2015, DOI: 10.4236/nr.2015.61001
Abstract: Floods are naturally occurring phenomena that are part of the physical and biological process which have shaped our nation’s landscape. It occurs in Nigeria environment when there is heavy rain fall for prolonged period of time. The data collection for this research was by use of primary and secondary information; questionnaire was administered by face to face interviews and key informant surveys. Analytical technique was the univariate statistical methods. The results revealed that there is clear evidence of damages to properties and that there are hazards and risks faced by these households as shown in Tables 1-4 respectively. Table 3 specifically shows the financial losses incurred annually by residents to the tune 5 million naira and above. However, the continued hazards and risks as a result of flood incidence have affected their overall income which hitherto is found within (N20000.00 - N25000.00) about 22.8% of the respondents fall in this income bracket. Furthermore, the research also revealed that about 30% say the flood has affected their income, while 29.4% say their buildings are affected. Also about 37.8% of respondents say that the flood incidence occurs all through the rainy season. The research recommends an aggressive review of the Port Harcourt Master Plan and the implementation of the development control tools in the 1992 Urban and Regional Planning Law.

Journal of Environmental Protection (JEP) , 2015, DOI: 10.4236/jep.2015.63027
Abstract: This study was carried out based on consistent observations on the activities of scavengers of scrap metal in Obio/Akpor local government Rivers State. The study was carried out to ascertain the profitability of scrap metal scavenging and how scrap metal waste can generate wealth to the public and the government. The study made use of primary and secondary data with the former being the main focus. The data were analyzed using the simple percentage, while the hypothesis was tested by means of the chi-square. The study findings revealed that there was a relationship between waste and wealth in relation to scrap metal scavenging. The researches therefore make the following recommendations; that scavengers should form co-operatives so that they can pull their efforts and resources together and bargain collectively. Government and nongovernmental organization should enlighten them through seminars, workshops, etc., on how to carry out their activities in an environmentally safe manner. The state government should encourage scavenging by enacting a law to back the profession and make it attractive for the teaming youths to venture into.

Journal of Environmental Protection (JEP) , 2015, DOI: 10.4236/jep.2015.64033
Abstract: Urban centers are consistently exhibiting higher temperature than its surrounding suburban rural areas. The large amount of heat generated from urban structures such as road materials and pavement materials and other anthropogenic heat sources are the main causes of Urban Heat Island (UHI). The sources of data for this research included primary and secondary sources. Other techniques employed for data collection were direct measurement and readings on the road and pavement materials. The research found out that, there was consistency in rising temperature at different time of the day by the different road and pavement materials. Asphalt has the greatest effect of increasing the urban temperature four degrees higher, followed by concrete, three degree rise in temperature, and earth (ordinary ground) by two degree rise and vegetation (grass) by one degree rise in temperature. The overall effect on the residents of the study area ranges from increase in hotness of the day; 44.6% respondents agrees; while 34.3% says it affects the ambient air quality of the area, and other effects such as increased ground level ozone, suffocation, sleeplessness and restlessness as a result of excessive high temperature especially at night are identified in this paper. The research recommends the review or redesigning of the entire Port Harcourt city Master Plan to make provision for creation of more green areas rather than pavements and concreted areas to reduce the effects of (UHI) and ultimately improve the comfort and living conditions of the people in a the garden city Port Harcourt.

Art and Design Review (ADR) , 2015, DOI: 10.4236/adr.2015.32004
Abstract: This paper starts with explaining the meaning of culture and cultural heritage. The researcher discusses the relevance’s of some of the material culture of the Igbo people, and how such materials could be preserved through the theatre. The development, presentation and preservation of Igbo art, Igbo symbol, Igbo mask, Igbo sound symbol, Igbo literature, Igbo festival and ceremonies through the theatre become necessary for advancement. A look at archival materials on Igbo art led to the submission that the Igbo and Nigeria artists can as a matter of fact draw inspiration from our rich arts and culture for better performances.
The Socio-Economic Impact of the Greater Port Harcourt Development Project on the Residents of the Affected Areas  [PDF]
Elenwo Ephraim Ikechukwu
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.31010
Abstract: This study investigates the relationship between the socio-economic affected Communities and the Greater Port Harcourt Development Project in Rivers State. The data used for study were obtained through questionnaire. The generated data were analyzed using the factor analysis and paired t test. It was observed that the computed t-scores (-2.729) and (-2.895) exceeded the values of t, indicated in the table. The T-test, values showed that the occurrence of hazards and risks on the residents of affected communities in Port Harcourt was significantly related to the activities of greater Port Harcourt project, and also the socio-economic life of residents of the communities was significantly affected by the activities of greater Port Harcourt project. The study has shown that there is an undercurrent of dissatisfaction with the greater Port Harcourt project in many of the comments put forward by the communities because of historical reasons. However, whatever reasons the host communities may have is manifestly not strong enough to stop the government in its proposal to transform the city decay to a world class city internationally recognized for excellence.
