ABSTRACT

A study on the effect Moringa Oleifera leaf extract on Citrullus lanatus was carried out at the Biological Garden of Usman Danfodiyo University, Sokoto. The aim was to determine the effect of Moringa leaf extract at different concentration on seed germination and early seedling growth of C. Lanatus (water Mellon). Aqueous extract was prepared by driving freshly leaf formed Moringa leaves e water and filtered out to obtain liquid extract which was then diluted with water in the following concentrations: 0ml, 20ml, 40ml, 60ml, 80ml. control treatment was set up using disliked water only. The six treatment were applied directly on C. lanatus seeds raised in 18 poly pots of 18cm long 2cm wide. The experiment was laid out in a completely randomize design in three (3) replicate. It was run for 15 days. Data were collected on number of leaves, stem high, root length, shoots fresh and dry weight at harvest, while germination rate was within 15 days of the experiment and where subjected to analysis of varience. Result obtain showed significant (P˂ 0.05) effect of the treatment on all the characters measured. Base on the results obtain, Moringa leaf extract has an improving effect on seed germination and growth of C. lanatus parts farmers are therefore recommended to adopt the use of this extract since it is easier, inexpensive, cheaper and can be obtain in large quantities in order to meet up demand of large hectares of land.

ABSTRACT

Several factors are responsible for neighborhood preferences and choices ranging from neighborhood attributes to benefits derived from it as well as personal values of neighborhood user.  As a geographically localized community within a larger city, it is of utmost importance for people to choose the kind of neighborhood they live therein. The quality of the neighborhood environments and their evaluations are so significant to the residents. These evaluations are often based on the diversity and complexity of personal senses of looking at the neighborhood setting as well as the varied lifestyles, personal demands, and preferences. More often than not, the choices of a given neighborhood are motivated or otherwise by the outcomes of the evaluations made by potential residents. The aim of this paper is to present factors influencing residents’ choices and preferences of neighborhood environments in Yola, Nigeria. The study was conducted within the methodological framework of means-end chain (MEC) research model, using the laddering interview technique. Ten respondents were interviewed, response recorded, transcribed and content analyzed. The results showed that several neighborhood attributes (proximity, family setup, accessibility, quietness, terrain, and not overcrowded) are reasons for preference and choice. Six of the Schwartz’s value domains of hedonism, security, universalism, achievement, self-direction, and benevolence were found to motivate these preferences and choices factors. It is important to plan neighborhoods that will engender safety of residents, make them very happy and give them a sense of satisfaction.

ABSTRACT

In Nigeria, Compensation valuation as a result of oil spill is undertaken based on the provision of the enabling laws and other relevant status. There are several augments as regards the factors to be considered  when valuing  for compensation payable as a result of oil spill. This study  aimed at ascertaining the benefits of incorporating long term impact of oil spills into oil spill compensation valuation. Compensation provision of the various laws were reviewed and found to only provide assessment and payment of compensation on land, buildings, crops and economic trees, no provisions was made for the long-term impact of the spill. Consequently, both primary and secondary data were collected through questionnaires and interviews. The analysis identified the benefits as; Increase in compensation payable, improvement on already existing claims factors, increase in pipeline maintenance and surveillance and reduction in oil spill incidences. Recommendations were made and if adhered to, there is the tendency that the present inadequate compensation crisis among polluters and victims which have caused serious and lengthy litigation in the court will be reduced to the barest minimum.  The researcher made the following recommendations having identified the importance of the long-term impact of oil spill in compensation determination, it is recommended that the long-term impact (value) of oil spill be incorporated into compensation valuation and the regulations governing compensation practices in Nigeria be reviewed, so as to incorporate long term impact of oil spill as an important factor in compensation determination.

ABSTRACT

In view of the usefulness of chemistry to nearly all fields of human endeavor, the poor achievement and retention of student in chemistry in college has been a source of concern. Most of the time, poor achievement and retention are caused by poor teaching methods used by chemistry teachers, therefore this study examined possible ways of enhancing chemistry students’ achievement by creating enabling learning community through activity based approach. The study employed pretest-posttest, control group quasi experimental research design. Chemistry achievement test (CAT) was developed by the researchers and administered to 150 chemistry student (boys and girls) in secondary school in SS2 from six (6) randomly selected secondary schools. Data were analyzed using descriptive statistics and the hypotheses were tested using chi-square which gave result that there is significant difference between student exposed to ABA and those exposed to conventional learning. Hypothesis one, t-calculated=23.605 and t-critical=1.960 with a significance level of p<0.05, hypothesis two t-calculated=0.623 and t-critical =1.960. Results obtained reviewed that students perform better in chemistry when taught using ABA as compared to conventional method. However, findings from hypothesis two reveal that gender has no significant effect on students’ academic achievement. Analysis of the study also found that post-test scores shows that experimental group had a mean score of 19.25 while the control group had a mean score of 8.62, this implies that ABA had a positive effect on the student’ academic achievement. It was concluded that ABA is more effective than conventional learning strategy. It was also recommended that ABA should be replicated in all science disciplines.

ABSTRACT

Ideology in architectural practice consists of architectural ideologies or the ideas that drive the styles and designs and the corporate ideology or the shared belief of the principal architects that guide the running of the architectural firm. Corporate ideologies play a significant role in strategy formulation, as an organisations’ core ideology is essentially the ‘glue’ that holds the organisation together. Studies have also shown that ideology has an effect on the firms’ management structure. Ideologies can also illuminate the core values of an organisation. Studies assert that core values are important tools of measurement when determining if organisational approaches are viable. Firm ideology as a component of firm culture is, by implication a critical factor for determining viability of the firm. The objectives include identifying the prevalent ideologies in architectural firms in North Central Nigeria, relating the ideologies to viable and sustainable architectural practice in Nigeria. The sample was derived from firms in the Architects Registration Council of Nigeria (ARCON) Register, purposively selecting cities where architectural firms were most concentrated in North Central Nigeria. The principal survey instrument was a structured questionnaire, and a total of one hundred and two (102) questionnaires were collated and analysed. Data from the questionnaires were also analysed using Pearson’s product-moment correlation coefficient, and regression analysis. Results of the study revealed most firms intuitively operated with architectural practice ideologies which significantly enhanced viability. These findings have created awareness that while Nigerian architecture practice does not show commitment to ideology, ideologies exist.

ABSTRACT

Nigerians are experiencing a lot of difficulties as a result of poor Generation, Transmission and Distribution of electricity. As of 2016, the electricity energy consumption in the world from the world fact book revealed that the average power per capital (watts per person) in the United States is 1,377 Watts. In Canada, it is as high as 1,704 Watts per person and in South Africa; it is 445 Watts per person. The average power per capital in Australia is 1,112 Watts and in New Zealand it is 1,020 W per person. Whereas, the average electricity consumed in watts per person in Nigeria is just 14 Watts.  This has put Nigeria in a rank of 189 out of 219 countries estimated. 

Currently, power generating capacity in Nigeria is estimated to be 6,803 megawatts, with average working capacity between 3,500 MW for over 170 million people (20.59 W/person). The power Companies in Nigeria face a lot of problems. Some of the highest priority issues being low generation of power, inadequate equipment and technical team for the clearance of faults, inadequate protection devices, transmission losses and low reliability of the distribution system. The Nigerian power problem has resulted to incessant planned, forced and unplanned outages. This has grounded many activities and has destroyed many industrial operations and processes. In addition, it has resulted to erratic and unreliable supply of electricity. It has reduced productivity and has increased unemployment and crime rates in the country. Hence, an analytical method is developed to study the dynamic- reliability of the distribution system, as well as optimizes the occurrence of faults and outages along the consumer point in each feeder in order to improve the performance of the system. A great need for fault evaluation and reliability studies of electric power system was observed. This research work analyzed the problems facing the Distribution System. Efforts were made to provide adequate solutions to the problems. The research work evaluated the occurrence and causes of faults and outages in the Distribution Network Area for a period of 8 years. In addition, it analyzed and reduced the effects of power losses along each of the feeders in the Distribution Network Area. This research work revealed the downtime, failure rate and reliability index along each of the eight feeders. It also improved the reliability and performance of the distribution system

ABSTRACT

Entrepreneurship involves identification and creation of a previously unexploited opportunities followed by will and initiative to seize these opportunities. The classical model of entrepreneurship involves creation of new venture, but modern entrepreneurial approaches are also an integral part of establishing corporate academics and government organizations. Polymer materials can be found everywhere nowadays, such as plastic water and beverages bottles, the silicon rubber tips on your phone, the nylon and polyesters in your jacket or sneakers, plastic hospital and domestic waste among others are all polymers. This paper tends to review the entrepreneurial opportunity from recycling of these waste plastic materials. The plastics materials can be recycled and reuse as packaging materials ranging for local soft drinks makers such as Sobo and ginger. Similarly different source of energy can be generated from these waste plastics ranging from solid briquettes, liquid fuels as well as combustible gaseous fuels. Therefore, these techniques such as recycling, reuse and energy generation from these waste materials can provide many entrepreneurial opportunities to teaming chemistry graduates as well as wealth creation, thus improving revenue generation to the nation entirely. Polymer recycling technique is also an amiable in reducing environmental problems caused by these polymeric waste accumulations on daily basis. It will also help in conserving our natural resources being from petrochemicals.

ABSTRACT

In this study we, developed and analysed a deterministic model for the transmission dynamics and control of Gonorrhea. Three nonlinear ordinary differential equations were used to describe this spread. The equilibrium points of the model are found and their stabilities are investigated. The basic reproduction number  was also calculated. The model exhibits two equilibria namely the disease free equilibrium in which all infected compartments are zero and the endemic equilibrium in which all the compartments are greater than zero. It was found that for, the Disease Free Equilibrium is locally asymptotically stable and unstable if otherwise.

Keywords: Stability, Disease Free Equilibrium, Gonorrhea,Basic reproduction number.
