ABSTRACT

The study assessed the Perceived Impact of Peer Assessment on Students’ Practical Skills Acquisition in Electronics Works Trade in Government Science and Technical Colleges of Adamawa State Nigeria’. To carry out the study, two research questions and two hypotheses were formulated. Descriptive survey research design was adopted for the study. Eighty-nine respondents comprising of eighty-three students and six electronics works trade teachers of Government science and Technical Colleges (GSTCs) of Adamawa state formed the population of the study. No sampling was used because the population was manageable. The instrument for data collection was a 57-item structured questionnaire named: ‘Impact of Peer Assessment on Students’ Practical Skills Acquisition Questionnaire (IPSPSAQ) developed by the researcher’. The instrument was validated by three specialists from the Department of Electrical Technology Education. Cronbach Alpha formular was used to compute a reliability index of 0.89 for the instrument. The instrument for data collection was administered to the respondents with the help of two research assistants; data obtained were analyzed using Statistical Package for Social Sciences. Mean and Standard Deviation were used to answer the research questions; while t-test statistic was used to test the hypotheses at 0.05 level of significance. The findings of the study indicated that gender does not have influence on students’ performance in electronics work trade in technical colleges in Adamawa state”. The findings also revealed that, Peer Assessment enhances students’ academic performance in Electronics Works Trade. Both the null hypotheses were upheld. The researcher recommended based on the findings that Electronics Works Trade teachers should adopt the use of Peer Assessment in assessing students since it has been found effective in improving students’ skills acquisition in Electronics Works Trade.  Government should organize workshops, conferences and seminars to train teachers on the use of Peer Assessment

ABSTRACT

Baobab is the most wide spread of Adansonia specie and is native to African continent. The generic name honors Michael Adason, the French naturalist and explorer who describe Adansonia digitata. All baobab trees are deciduous, losing their leaves in the dry season and remain leafless for nine months of the years. They can grow to between 5-25m (16-82 ft) in height. They are in fact known both for their height and trunk’s girth. The trunk tends to be bottle-shaped and can reach a diameter of 10-14m(33-46ft). The Adansonia digitata (baobab) was bought from Sokoto state central market. The fruit (seed and pulp) were analyzed for proximate and mineral composition using AOAC (2003) method. The moisture content of baobab seed and pulp were found to be 8.0 ± 0.52 and 14.0 ± 0.52, the ash content 6.5 ± 0.52 for the seed and 5.5 ± 0.52 for the pulp, the % lipid; pulp contains 1.5 and seed was found to contain 8.5. The fiber in pulp was found to be trace and 1.5 in seed. The nitrogen free in pulp was found to be0.294 and in seed found to be 1.624. the % crude proteins in pulp was also found to be 1.84 and in seed was found to be 10.15. the % carbohydrate (CHO) in pulp was found to be 77.16 and that of sees found to be 65.35 respectively. For the minerals analysis, sodium (Na) in pulp was found to be 72.5mg/kg and in seed 87.5mg/kg, potassium in baobab pulp found to be 5500mg/kg and in seed found to be 3500mg/kg. calcium content was found to be 0.45mg/kg in pulp and 0.55mg/kg in seed, magnesium content was found to be  1.30mg/kg in  baobab pulp and 1.90mg/kg in seed and finally phosphorus content in baobab pulp was found to be 5.26mg/kg and that of baobab seed found to be 8.11mg/kg respectively.  The plant has many health benefits which include; anti-inflammatory, anti-diarrhea, antioxidant, antiviral, control of blood sugar, absorption of iron, anti-fever among other.

ABSTRACT

This study examined the safety measures and effective management of radioactive waste in an environment especially from radioactive waste from nuclear reactor, through theoretical review of some of the basic principle involved in waste management of radioactive material. Radioactive waste comprises a variety of materials requiring different type of management to protect human and their environment. They are normally classified as low – level, medium level and high-level waste according to the amount and types of radioactivity in them. The waste is both concentrated and then isolated, or it is dilute to acceptable level and then discharged to the environment. Delay and decay involve the storage of the waste and its radioactivity is allowed to decrease naturally through decay of the radioisotopes in it. This study is aim to enlighten the public on the way to manage radioactive waste in such a way which can safeguards human health and minimizes the impact to the environment nuclear plant is install.

ABSTRACT

The study examines fuelwood consumption rates. Data was obtained from a survey of 250 systematically selected household, out of which 243 were successfully retrieved, 104 were systematically selected from non-households. The data was subjected to descriptive statistics analysis. The result showed that the rate of fuelwood supplied and consumed was high as both fuelwood supplied and consumed is sourced from or within the area. It is recommended that to avoid total collapse of the ecological balance of the study area, a conscious and sustained afforestation and reforestation programs must be embarked upon. The promotion of the cheap, reliable and safe alternative to fuelwood would free large number of woodland trees which could be used in other woodland demands.

ABSTRACT

The aim of this study is to assess the quality of the shallow groundwater quality of Michika area of Nigeria for irrigation and domestic purposes. Geological mapping revealed the area is underlain by granitic rocks of Pan-African age. These rocks are grouped into three types: coarse grained biotite granites, coarse porphyritic granites and medium grained granites which are intruded by the new basaltic rocks of Tertiary age. Forty water samples collected from wells tapping shallow aquifer were used. Chemical analyses were performed in the laboratory employing standard methods viz Atomic Adsorption Spectrophotometry for cations and conventional titration for anions. In addition ions in milligram per liter were converted to mill equivalent per liter and anions balanced against cations as a control check of the reliability of the analyzed results. The analyzed chemical parameters were interpreted and the result revealed that most of the samples are slightly acidic to alkaline, largely soft with fairly low to moderate concentrations of dissolved solids that fall within the international limits for domestic purposes. However, the concentration of iron and nitrate in less than 1% and 25% respectively is higher than the maximum acceptable concentration of 0.3 mg/l and 10 mg/l respectively and should be treated before use. The hydro geochemistry of the study area indicate two water type that is Ca-mg-HC03 and Na-C03 for both hand dug well and boreholes Thus most of the samples will neither cause salinity hazards nor have an adverse effect on the soil properties and are mostly suitable for domestic and irrigation purposes.

ABSTRACT

The private sector in housing provision continually take steps towards addressing part of the problem of cushioning the effect of housing shortage in Nigeria by establishing housing estates since government alone cannot provide housing for everyone. This research examined and reported findings from a research conducted on the state of repair of buildings in private housing estates in Enugu metropolis, Enugu state Nigeria. The objectives of the study were to: examine the physical conditions of the building fabrics and appraise the performance of infrastructural services provided in the buildings. Questionnaire was used as research instrument to elicit data from respondents. Stratified sampling of the estates based on building type was adopted as sampling method for this study.Findings from the research show that the state of repair of most buildings require minor repairs to make them fit for habitation and sound to ensure well-being of the residents. In addition, four independent variables from the nine independent variables investigated, significantly explained residual variation in the dependent variable – state of repair of the buildings in the study area. These variables are: Average Monthly Income of Residents (AMIR), Length of Stay of the Residents in the estates (LSY), Type of Wall Finishes on the buildings (TWF) and Time Taken to Respond to Resident’s complaints by the estate managers (TTRC). With this, linear model was established for predicting the state of repair of buildings in private housing estates in the study area. This would assist in identifying variables that are lucid in predicting state of repair of the buildings.

ABSTRACT

Museums are places of natural and human creativity as well as history. The aim of museums is to provide examples of each classification available for a field of knowledge. Museums employ two main strategies for its lighting which includes: daylighting and artificial lighting. This study was able to identify and discuss the different daylighting systems, and the existing museums which used daylighting were analysed properly to see how daylighting was harnessed in their respective internal spaces. The research methodology used for this research work includes case studies and extensive literature reviews. Deductions from these case studies showed the various natural lighting techniques used which include clerestory windows, luminous ceilings and cove luminaires. All of these played a major role in harnessing daylight in the museums studied. In the course of research, Lighting is significant in museum artifact display, as it helps with the interaction between the artifact and the human in a defined space. Daylighting, as it is significant to the artifact, if not properly controlled, can cause discomfort in the eyes of the observer, at the same time be destructive to the objects on display. Other methods used for introducing daylighting into the spaces include the use of diffuse lighting throughLuminous ceilings,skylights, cove luminaires and also clerestory windows which help light reflects deeper into the exhibition halls. The design parameters and considerations indicate that buildings using these methods use less energy to lighten up their spaces, at the same time improving visibility and appreciation of artifacts.

ABSTRACT

It is well ascertained that for water to penetrate a wall, this three conditions must be true at the same time and location: Water on the surface of the wall, An opening through which water may pass, Any one of five external forces which include surface tension, momentum, air pressure differences, gravity flow and capillary action. Capillary Action (Capillarity) is the movement of water (or any liquid) through a tube. Moisture which is the relative amount of water vapor contained is the air is generated through several source and cause lot of harsh effect on the building and its content. Possible strategies that will mitigate this effect are what this paper seek to highlight and resolve critically by emphasising the possible guidelines that will that will mitigate regular occurrence.Keywords: Relative Humidity, Moisture control, Capillary action Mitigation

ABSTRACT

Buildings are meant to complete their service life before undergoing deterioration, but this has become a mirage in the building lifecycle because of negligence in the careful conceptualization of designs. Design for maintainability, with emphasis on access to maintenance deals with creating proper designs that will incorporate accessibility that will enhance and enable maintenance. This will mitigate building defects, combat inappropriate and buildings that are not conceptually sustainable in designs and thereafter increase the maintenance culture of buildings in Nigeria. The negligence of the subject matter has caused buildings to encounter multiple defects, deterioration, and obsolescence in edifice that would have served their functions completely before the end of their service-life. Therefore, this paper seeks to adopt an analytical approach through the comparism of related journals, books to resolving this ever-trending challenge in the building and construction sector.

Keywords: Design maintainability, building life cycle, sustainability, accessibility.
