  • Utilisation of Nanomaterials in Improving Bitumen and Asphalt Mixtures
           Characteristics: A review

    • Authors: Hamad Al-Ajami
      Abstract: This paper reviews the utilisation of nanotechnology in improving bitumen and asphalt mixtures characteristics.  Nanotechnology means the ability to take control of matter at nanometer scale and to take advantage of the phenomena and properties of this dimension in tools, materials, and modern systems. Researchers and engineers have explored the potential of nanotechnology for many years, products based on this new technology will cause major mutation in the quality of life, economic displacement and environmental and defence capabilities. Therefore, public and private sectors in countries such as Europe Union, United states and Japan are in intense competition for being the worlds leading in one area of this technology at least. The nanotechnology is widely applied in pavement engineering nowadays, in order to enhance the properties and performance of the materials. This paper showed that adding nano-particles such as: nanosilica, nanoclay, and nanotubes to the asphalt mixtures improve the rutting and fatigue resistance of the asphalt mixtures and increase the viscosity of asphalt binders. Keywords: Nanotechnology; Asphalt mixtures; Nanoclay; Nanotubes; Nanosilica.

  • Effects of Global Climate Change on Wildlife: A Review

    • Authors: Wondimagegnehu Tekalign
      Abstract: Global warming, which is also referred to as climate change, is an increase in the world’s temperature, believed to be caused in part by the greenhouse effect. Climate change can have serious consequences on a variety of species and their habitats. Accumulation of carbon dioxide, methane and other greenhouse gases in the atmosphere is the root cause of global warming. Anthropogenic activities such as deforestation, extensive burning of fossil fuel, commercial agriculture, chemical industries and automobiles contribute highly for greenhouse gas emission. Every year, human activities release 28 billion tones of CO2 and half of which remains in the atmosphere. About 80% of CO2 emission is from industries and the rest is affected by land-use changes including deforestation. With continued and more severe changes in the climate, the ability of wildlife to adapt through physiological and behavioural changes will be increasingly limited. It is clear that global warming has started negatively affecting a wide variety of wildlife worldwide. Extinctions have started, and much wildlife is being pushed closer to extinction or local extermination as a direct or indirect result of climate change. For the continued existence of wildlife, it is essential to limit greenhouse gas emissions and mitigate the threat of global warming. Key words: Adaptation, Climate change, Global warming, Green house effect, Mitigation, Wildlife

  • Economic Model for Household Solid Waste Collection

    • Authors: Mustafa Elkhedr
      Abstract: Protection of public health and water resources is partly maintained through efficient waste collection. This paper presents a model to calculate collection and transfer cost of household solid waste. The model was applied to estimate the collection and transfer cost of household waste for a district in Cairo, Egypt. The model was calibrated and verified using data that was collected through surveying 30 waste collectors. The model is applied for both new and used trucks and was successful in determining the required fee to be collected per household and per ton of waste. The collection and transfer cost model is based on variable and fixed costs. Collection and transfer costs, in Egypt, were less than those presented in literature. This was attributed to lower labour cost and lower capital costs needed for waste collection and transfer. Keywords: Municipal solid waste management system; Collection and transfer cost; Household Waste, Waste collection model

  • Assessment of Maintenance Management Culture of Tertiary Institutions in

    • Authors: Samuel Olusola; Olatunji, Douglas Omoregie, Aghimien, Ayodeji Emmanuel, Oke, Akinkunmi, Temitope
      Abstract: Buildings are critical factors in achieving desirable outcomes for tertiary institutions. Any inadequacy in building facilities represents a loss in value of the institution, its users and stakeholders. Hence, institution buildings require maintenance in order to create a conducive environment that supports and stimulates learning, teaching, innovation and research as there seems to be a strong correlation between learning and the environment in which knowledge is imparted. In this research, maintenance management structure of tertiary institutions was assessed and the usual maintenance procedures as well as means of funding maintenance activities in the institutions were examined and evaluated. Data used for this research work were collected using structured questionnaires and interview which were administered to workers of the various departments in charge of maintenance work. Data received were analyzed using simple statistical tools such as mean item score, percentage and frequency. The research shows that institutions have a structure in place to carryout maintenance work but do not have a formal organogram showing the hierarchy flow of authority and that maintenance department is characterized by inexperienced staff. It also revealed that maintenance works are properly funded but characterized by frequent occurrences like underestimating and cost overrun. The research recommends that the institution should have a formal organogram to show the distribution of power and to carry out proper training of maintenance staff especially the quantity surveyors in preparing maintenance budgets. Keywords: Tertiary Institutions, Maintenance, Maintenance Department, Maintenance Practice, Nigeria.

  • Assessment of the Quality of Drinking Water Supply, and the Status of

    • Authors: Tegomejech D. Daniel, Daniel F. Fitamo, Brook A. Abate, Alemu O. Osore
      Abstract: Limited access associated with poor water supply, hygiene and sanitation is widening the poverty gap, gender inequality and prevalence of water born diseases. This research work is aimed to examine the quality of existing water supply, sanitation and hygiene status of Mudula Town. To achieve this objective, the household survey and Water samples were collected from three water sources (spring), storage and taps. With the exception of Kalahiwot spring for Turbidity (7.75NTU), all others were within the standards. For bacteriological analysis, Gofore spring is within the standard. But samples tested from Bada and Kalahiwot did not meet the WHO and EPA bacteriological standards for drinking water. The correlation result of physical parameters shows that for all sources turbidity, TDS and EC has strong positive correlation with each other. With the exception of Gofere spring source, fecal coliform (E.coli) is negatively correlated with Temperature and positivity correlated with Total coliform for both spring water sources. The current average per capital water converge in the area is 68% and its consumption is strongly correlated with house hold income amount. Similarly for sanitation, from total respondents 5% use pit latrine without house, 10% pit latrine with house and remain 85% use pit latrine with wall and roof. Regarding to solid waste, 55% dispose solid waste on garden and 45% have sanitary pit. From total respondents, up to 55% do not use water after defecating. The rest also have a gap on using soap continuously. Therefore, to overcome the problems regular chlorination of water, sanitation and hygiene practicing awareness may be required. Keywords: Water Supply, Coverage, Water Quality, Sanitation and Hygiene practices

  • Sediment Yield Assessment for Tannur Dam Reservoir in Jordan

    • Authors: Abbas Ijam, Areej Al-Bdoor
      Abstract: Reservoir sedimentation is caused from erosion process in the catchment area, the sediment build up in the reservoir, reduce its capacity and affect the aim for which the dam was constructed. This study presents an application of the Soil and Water Assessment Tool (SWAT) to simulate the water and sediment yield for Tannur dam reservoir in Jordan. The model was calibrated and verified using the monthly average surface flow and sediment measurements at Tannur gauging station. The optimum curve number (CN) was found in the range 82 to 86 and land cover factor (C) in range 0f 0.003 to 0.03. Model validation results estimated the total volume of water of 110.5 MCM and total amount of sediment yield of 0.8 million ton reached Tannur dam reservoir during the period from October 2003 to December 2009. Total sediment yield of 2.5 million ton was predicted for the period 2010-2030. Subbasins 14 and 30 are more susceptible to soil erosion and sediment yields. The present work could assist in quantifying sediment yields in the long-term as well as in identifying the most susceptible areas within the catchment in order to assist policy makers in taking cost-effective management decisions. Keywords: Sediment yield, Erosion, Reservoirs, Tannur dam, Jordan

  • Obligation and Violation of Safety Standards in Construction Industry of

    • Authors: Muhammad Yousaf, Ahmad Bilal khattak
      Abstract: In developing countries like Pakistan, construction is one of the most hazardous industrial sectors. Every year, thousands of workers received serious injuries and accidents and this uninterrupted dilemma is growing day by day. Due to this alarming position, there is a need to evaluate the construction accidents along with their causes related to them. This research presents the identification of the factors contributing to construction accidents in Pakistan and suggests key prevention measures on the basis of statistical analysis. A survey questionnaire has been developed and used for the data collection. In total, 164 respondents ranging from foreman to unskilled labor were approached and the questionnaires were filled. Response rate was excellent resulting in 143 valid responses. The results were analyzed and ranked. The accidents are attributed mainly due to. (a) tool accidents; (b) fall from height; and (c) struck by material. Results indicated that management factors largely contributing to the accidents causation rather than workers factors or social factors and need serious consideration. Based on the results of the analysis, prevention measures are recommended which includes: (i) involvement and commitment of top management; (ii) safety education in terms of training for all managers and supervisors; (iii) awareness and identification of unsafe work practices (iv) necessity of personal protective equipment and first aid equipment; and (v) reporting and maintaining injuries and accident records. This work may be useful for the construction practitioners to minimize the accident rate at High rise building construction Projects.

  • Post Contract Cost Management Practices of Contractors in Nigeria

    • Authors: Opeyemi Oyeyipo, Kole Odusami
      Abstract: It is a well-known fact that a lot of problems have arisen during the construction projects implementation; out of which, the main distinctive problem is cost overruns. Cost overruns are evidently frequent problems in the construction industries of many developed and developing countries. Once the construction projects implementation begins, the project's costs rarely remain static. There is need for cost control on the part of contractor in order to guarantee profit and ensure the continued achievement of long term goals of the company. This study was therefore carried out to examine the post contract cost management practices of contractors in Nigeria. The study examined the frequency of use of contractor’s cost control methods and their effectiveness. A cross-sectional survey research design was adopted for the study. A structured questionnaire was used as the principal instrument for collecting data from respondents. Random sampling method was used to drawn up sample from the population. A total sample of eighty (80) was drawn from these collections of building construction contractors of various categories (small, medium and large) from Lagos, Nigeria. Thirty four (34) were completed and returned representing a 44% response rate. Frequency, percentage, mean score, spearman rank order correlation and analysis of variance were used in analysing data collected for the study. Findings reveals cost projection measure is the most frequent cost control method used by contractors, while actual versus forecast reconciliation (labour/material/plant) is regarded as the most effective control method. Expatriate and partly expatriate contractors agree on the effective cost control methods in the construction industry. It was recommended that building contractors should ensure reliable and accurate cost estimating, the quantification of actual costs for labour, equipments and plants should be done on site during construction to ensure cost control on construction sites. The feedback which requires adjustments during pricing future estimates should be kept and updated in the form of bills of quantities. This study further recommends contractors should embrace cost control methods which ensure close monitoring and reporting of work progress and cost performance. This is very important for effective cost control process during post contract stage. The report also claimed that IT integration is the only way to get quick and accurate reports to solve cost overrun and its associated problems identified by several literature and professionals. Keywords: Construction project, cost control, cost overrun, Nigeria, post contract.

  • Load - Deflection Characteristics of Reinforced Concrete and Reinforced
           Latecrete Beams at Mid-Span

    • Authors: Samson Imoni, Stephen Pinder Ejeh, Ugama Ikande Terry
      Abstract: A laboratory Investigation of the Flexural Strength of Latecrete materials was carried out. The laterite used falls under AASHTO soil classification A-7-6 (10) with low plasticity clay (CL) according to the Unified soil classification system. This laterite is within zone four gradation characterized by fine laterite and has kaolinite as its dominant clay mineral. The Experimental programme involves the fabrication of twenty beams of concrete and latecrete materials; and testing them for flexural strength. Tests show that The Flexural strength recorded for plain concrete beams was 2.89 N/mm2, while plain latecrete beams has a value 1.44 N/mm2. The flexural strength of 13.58 N/mm2 was recorded for the reinforced concrete beams and 7.80 N/mm2 for reinforced latecrete beams, indicating that the flexural strength of latecrete beam is approximately 50% of that of concrete beam specimens. The load-deflection behaviors of the beams are essentially linear within the elastic range of loading. Based on the findings of this investigation, it was observed that the behavior of latecrete is similar to that of concrete; however, the concrete materials showed better strength characteristics than the latecrete materials. Keywords: Concrete, Latecrete, sand, Reinforcement and flexural strength.

  • Qualitative Assessment of Effects of Encroachment on Water Resources of
           Agba Dam, Ilorin Nigeria

    • Authors: O. S. Oladeji, R. A. Olaoye, I. B. Abioye
      Abstract: The city of Ilorin in Nigeria has experienced high population growth and rapid urbanization. Agba Dam is one of the major sources of potable water in Ilorin, and currently been threatened by anthropogenic induced encroachment activities, with potential for significant derogatory effects on its quality. Therefore, this paper assesses the qualitative impact of encroachment on the water resources regime of Agba Dam, Ilorin, Nigeria. Field survey was carried out to scope proximal anthropogenic activities and to delineate historical and current extent of the encroachment area of the dam. Representative water samples were collected from locations within the dam catchment, and subsequently analyzed for alkalinity, dissolved carbondioxide, chloride, total iron, copper, sulphate, colour, calcium, dissolved oxygen and turbidity. In addition, historical physical and chemical data of water samples obtained from the dam were also acquired, and analyzed to determine temporal variation in the quality. The results show a reduction of 0.89 km2 or 63% in the historical buffer boundary of the dam. The values of the measured physico-chemical parameters were generally similar to that obtained for the historical values and therefore suggest limited impact of the anthropogenic activities on the water quality. However, slight increases were observed in the measured concentrations of the alkalinity, dissolved carbondioxide, chloride, iron, copper and sulphate, and this indicates possibilities of water quality alteration, with potential consequences for ecosystem and aquatic life if the trend is unabated. Keywords: Anthropogenic, Water quality, Agba dam, Ilorin Nigeria
