  • Environmental Burden of Heavy Metal Contamination Levels in Soil from
           Sewage Irrigation Area of Geriyo Catchment, Nigeria

    • Authors: Hong; Aliyu Haliru, Law puong Ling, Onni Suhaiza Selaman
      Abstract: The heavy metal concentration levels and contamination/pollution index of agricultural soils taken from 0 – 30 cm depth from site I and II of sewage irrigation area and from a control site of Geriyo catchment in Adamawa State, Nigeria was determined using atomic absorption spectrophotometer standard method. The mean concentration levels of trace and heavy metals (Fe, Zn, Mn, Cu, Cd, Cr and Pb) at site I are 89.90 mg/kg for Fe, 74.39 mg/kg for Zn, 12.79 mg/kg for Mn, 15.09 mg/kg for Cu, 9.86 mg/kg for Cd, 11.2 mg/kg for Cr and 7.18 mg/kg for Pb, while at site II, the concentrations levels of  294.7 mg/kg for Fe, 310.2 mg/kg for Zn, 131.9 mg/kg for Mn, 254.8 mg/kg for Cu, 240.2 mg/kg for Cd, 199.6 mg/kg for Cr and 159.2 mg/kg for Pb were observed. The concentration levels of trace and heavy metals of site II soil is significantly higher than site I and the control site with values of (Cu, Cd, Cr and Pb) mostly above the maximum permissible heavy metal concentration levels in soil set out by EU, UK and USA. The contamination/pollution index assessment of the soils revealed that the soils belong to slight pollution to excessive heavy metal pollution soil category with the potentials of negative effect on plants and ground water reserve contamination. Leaching and liming of the soil to reduce the level of metals is recommended in the context of very high land competition for sustainable agricultural productivity.

  • Effect of Activated Sludge Preservation on Its Adsorption Capacity in
           Treatment of Wastewater

    • Authors: Miriam Tsiboe, Emma Haun, Karl-Heinz Rosenwinkel, Julius Musyoka Ndambuki
      Abstract: Adsorption by activated sludge which plays a significant role in substrate removal has received a lot of recognition. A number of studies have been conducted into understanding this mechanism. However, the impact of activated sludge preservation on the adsorption capacity test results has not been documented. Live activated sludge is usually preserved after sampling to maintain the original sludge characteristics in order not to alter its adsorption capacity. Preservation of the sludge is relevant when the sludge has to be transported over long distances before adsorption experiments can be conducted. This paper seeks to present the effects of preservation of activated sludge on its adsorption capacity. The preservation methods considered were pre-aeration and cold-storage of the sludge. Sludge samples were pre-aerated for periods of 4 and 24 hours at room temperature and some were stored at 4?C for 6 hours. Adsorption batch experiments were then carried out on both fresh and preserved activated sludge samples. Glucose was used as an external substrate in these experiments. The results revealed a difference between the adsorption capacity of the fresh and preserved sludge samples. Sludge pre-aeration increased the adsorption capacity of the sludge. There was however, no significant difference in the adsorption capacities for 4h and 24h pre-aerated sludge samples. Adsorption capacity of the 6h cold-stored activated sludge was poor compared to that of the fresh sludge. Keywords: Activated sludge, Activated sludge preservation, Adsorption capacity, Glucose

  • Agricultural Waste Pulping in Nigeria: Prospects and Challenges

    • Authors: Ogunwusi; A.A
      Abstract: The paper industry in Nigeria has undergone serious travails as a result of the high dependence on imported inputs, most especially, long fibre pulp.  Thus, Nigeria depend extensively on paper importation.  As the nation is an agricultural country, it generates substantial volume of agricultural waste in all its ecological zones.  The waste can be a sustainable source of raw material for the nation’s pulp and paper industry.  The utilisation of agricultural waste as raw material for the paper industry had been going on in a number of countries that does not have sustainable supply of wood.  This practice will substantially assist the nation in eliminating the current import dependence of the paper industry to a reasonable extent. Keywords: pulping, waste, kraft, soda, straw.

  • Biosorption of Ni(II) Ions from Electroplating Industrial Effluent using
           Tinospora cardifolia Biomass

    • Authors: Kajal Sao, Madhurima Pandey, Piyush Kant Pandey, F. Khan
      Abstract: A biomass derived from the plant Tinospora cardifolia has been found to be very efficient in Nickel(II) adsorption. An attempt was made to use this biomass for Nickel(II) removal under different conditions. The parameters optimized were contact time (5–1440 min), pH (1–10), concentration of adsorbent (1–7 gm/L), concentration of adsorbate (10–500 mg/L), etc. It was observed that the pH had a strong effect on biosorption capacity. The optimum pH obtained for nickel adsorption was 4.0. The influence of common ions such as Cu(II), Zn(II), Cd(II), Fe(III), Mn(II), Pb(II) and Cr(VI)  and NO3-, SO4- PO4- and Cl- at concentrations varying from 10 to 500 mg/l was investigated. To establish the most appropriate correlation for the equilibrium curves, isotherm studies were performed for Ni(II) ion using Freundlich and Langmuir adsorption isotherms. The pattern of adsorption fitted well with both models. The biomass of T. cardifolia was found to be effective for the removal of Ni(II) with 92.3% sorption efficiency at a concentration of 50 mg/l of Ni(II) solution, and thus uptake capacity(qm) according to Langmuir isotherm is 4.48 mg/g of biomass and in column mode 2.49 mg/g of biomass. Keywords: Nickel; Adsorption; Biomass; Tinospora cardifolia

  • Analysis of Blast Loading Effect on High Rise Buildings

    • Authors: A. V. Kulkarni, Sambireddy G
      Abstract: This paper presents the dynamic response of a High Rise Structure subjected to blast load. The fundamentals of blast hazards and the interaction of blast waves with structures are examined in this study it is about the lateral stability of a high rise building modeled using SAP2000. The model building was subjected to two different charge weights of 800lbs and 1600lbs TNT at a two different standoff distances of 5m and 10m.The blast loads are calculated using the methods outlined in section 5 of TM5-1300 and a nonlinear modal analysis is used for the analysis of the dynamic load of the blast. The primary performance parameters that will be used to evaluate the behavior of the building from a global perspective are the total drift and the inter-storey drift. They are good indicators of nonstructural damage, collapse and ability of the structure to resist P-delta effect. Behavior of R.C frame and concrete infill frame will be computed in Dynamic condition Keywords: Blast loading; Inter-storey Drift; Standoff Distance; TNT; Positive Phase

  • The Effect of Superplasticizer Type on Compression Failure of
           High–Strength Concrete

    • Authors: Chatarina Niken, Elly Tjahjono, Bambang Soegijono, Vera Indrawati
      Abstract: Although superplasticizer has been used widely on buildings and bridge structures around the world, the concrete’s behavior has not yet been understood well by civil engineers.  The use of superplasticizer should guarantee that abnormal failure does not occur. This paper presents  different compression failure types of cylindrical specimens using two kinds of superplasticizer based on experimental research for compression test of high strength concrete  (HSC) with a minimum compressive strength of 60 MPa. Cylindrical specimens measuring 15 cm in diameter and 30 cm of high were used. Seven mixtures using H superplasticizer and 7 mixtures using V superplasticizer were used. Failure observations were conducted as compression load was applied until failure occured. There were two types of compression failure which were vertical and horizontal according to two types of FT-IR graphs of superplasticizer. FT-IR simple fingerprint of superplasticizer exhibited normal compressive failure, while complex fingerprint showed dangerous compressive failure.

  • Sustainable Construction: Comparative Advantages of Expanded Polystyrene
           (EPS) Fascia in Housing Delivery in Nigeria

    • Authors: Ibukunoluwa A. Ogundiran, Y. M. D. Adedeji
      Abstract: Various environmental challenges posed by the application of non-sustainable construction materials and techniques and higher cost of same in the recent time have made the search for better and cheaper alternatives a crucial task in the provision of housing in Nigeria. As a product of research and technological advancements, modern eco-friendly building materials are currently emerging to satisfy the requirements of sustainable developments and mitigate environmental challenges. One of such materials is the expanded polystyrene or EPS. This paper focuses on sustainable construction with emphasis on the comparative advantages of expanded polystyrene fascia over the conventional concrete fascia in the delivery of housing in Nigeria. The data for the research were obtained through primary sources of data gathering. This involves primary stage of purposeful selection from two cities namely Abuja and Akure, Nigeria, where the material (EPS) was extensively used in housing estates. Analysis of the findings from the two housing estates selected as case studies, reveal that EPS fascia demonstrates faster construction time, flexibility of design, lesser number of labor to be engaged, higher strength, cheaper cost and higher sustainability potentials over the conventional concrete fascia used for similar housing units in same locations. While it was discovered that there is little or no availability of the material in most Nigerian building markets due to lack of awareness among the various stakeholders and practitioners in the building industry, it x-rayed the need for a paradigm shift from the conventional system of building characterized by waste, cradle to grave (demolition) and global warming to a waste-free, recyclable, eco-friendly and cheaper alternative way of building construction.

  • Geohazard Evaluation of Bukit Merah/ Malaysia using Geospatial Information
           Technique

    • Authors: A'kif Al-Fugara, Rida Al-Adamat, Omar Al-Kouri, Saleh Taher
      Abstract: Geospatial technology (that includes Remote Sensing and Geographical Information System GIS) has opened up opportunities for qualitative analyses of sinkholes distribution with multi thematic maps to define the relationship of GIS database. Kinta Valley have been deteriorating dramatically as a result of changes that had occurred in the past and continues due to the close relationship between the fast rate of lateral urbanization and extensive dimensional expansion of surface mining and quarrying activities, where sinkholes are the main crux of the geohazard in Kinta Valley. Geospatial information system for sinkholes had been established using pictorial, tabular and ancillary data to build a relational GIS database. The application is capable of analyzing an entire data set of sinkholes to create sinkholes distribution map. The objective of this paper is to highlight the value of Geospatial Information System as a tool to define sinkhole distribution and change detection for geohazard evaluation. Keywords: Geospatial, Karst, Sinkholes distribution, Geohazard, Malaysia.

  • An Experiment to Determine the Prospect of using Cocoa Pod Husk Ash as
           Stabilizer for Weak Lateritic Soils

    • Authors: Anthony Woode, David Kwame Amoah, Daniel Nartey, Daniel Misefah, Felix Anyetei Nai, Robert Abane Nsoh, Nuamah Isaac Addae
      Abstract: A study was conducted to determine the extent to which the engineering and geotechnical properties of a lateritic soil for road construction works can be improved by using cocoa pod husk ash (CPHA) additive.Natural lateritic soil samples were collected from test pits near El wak Sports Stadium, Accra, Ghana and were subjected to Atterberg’s limit and particle size distribution tests as well as compaction and California Bearing Ratio (CBR) tests. The soil was then treated with 0.5%, 1.0%, 2.0%, 4.0%, 6.0%, 8.0%, and 10.0% of CPHA and then tested for variations in the engineering properties.From the various tests carried out on the natural soil sample, and when CPHA was added, it was observed that CPHA has a significant negative effect on the maximum dry density and a positive significant effect (p<0.05) on the liquid limit. The addition of CPHA to the soil however, did not significantly (p>0.05) affect the California Bearing Ratio, optimum moisture content, plastic limit and plasticity index, and therefore the CPHA is regarded as a poor soil stabilizer. Other findings show that CPHA has no pozzolanic properties. Keywords: Cocoa pod husk ash, stabilizer, lateritic soil, pozzolanic properties

  • Multicultural Work Force in Construction Organisation – Issues of
           Health, Safety & Environment

    • Authors: David Ngwoke Mbazor, Sunday Okuoma Okoh
      Abstract: Multicultural workforce dominates emerging construction Organisation in today’s global business environment and consists of teams from different nationalities with diverse cultural orientations and values. The study examined how issues such as changing age, sex, religion, ethnicity, physical ability, race, sexual orientation of employees affect health, safety and environment. Issues such as language or communication barrier, cultural challenges, religious differences, practice/technological issues are some of the challenges that project and construction managers must embrace and address squarely. It was therefore recommended that construction Organisations must have a unit charged with cultural orientation, language training and better utilisation of government policies regarding migration of workforce.

           Case of Makongo in Dar es Salaam Tanzania

    • Authors: Joseph Paulo Layson, Xia Nankai
      Abstract: This paper examined the community initiated redevelopment in Makongo juu , Tanzania. it is a bottom up planning, researchers were interested  on assessing the redevelopment process, examining the achievements, opportunities and challenges.Based on predictions, almost 60% of the world population will be living in cities by 2030.Tanzania is urbanizing at a rapid rate 4.7% in which 26% of the total population lives in urban area. Planning and implementation of urban redevelopment projects based on public funds has been facing challenges. Thus bottom up approach and community involvement in improving housing and living condition has been a best alternative.Currently the concept and adoption of bottom up planning is one of the most commonly adopted in recent time. In early 1990s, Makongo juu residents in Dar es salaam Tanzania realized that many projects in the settlement could not be implemented through normal government funds, they formed an initiatives to solve their problems. Currently Makongo Juu area in Dar es Salaam, Tanzania is set for major facelift including redevelopment of infrastructures such as roads and improved Housing. About 17,000 residents of the area are affected by the exercise with area covering about 1500Acres. This is a community initiated project by Makongo juu residents. Through explorative research using case study strategy; official, key informant’s interview and in-depth household interview were conducted. This paper examined the application of the concept in the urban redevelopment process in Makongo juu .Achievements are given; problems faced examined and possible solutions are put forward. Challenges and opportunities for replication in similar environments are discussed. A total of 106 people we interviewed in Makongo juu in which 47% were females, and 53% were males. Findings revealed that willingness of residents to release part of their plots for improving public infrastructure has been a challenge. Keywords: bottom up planning, redevelopment, Housing.

  • Effect of Iron Ore Tailing on the Properties of Concrete

    • Authors: T. I. Ugama, S. P. Ejeh, D. Y Amartey
      Abstract: Experiments were conducted to determine the suitability of iron ore tailing (IOT) as fine aggregate replacement of sand (RS) for concrete used for rigid pavement. The use of iron ore tailing (IOT) from Itakpe mines near Okene in north-central Kogi state of Nigeria will ensure economy in concrete production as well as a better way of disposing the tailing. Mix design was carried out for concrete of grade 35 using standard practice for selecting proportions for normal weight, and mass concrete [ACI 211.1-91, 1997]. The constituent materials were batched by weight. The mix with only sand as fine aggregate served as the control mix, while sand was replaced in the other mixes by 20%, 40%, 60%, 80% and 100% iron ore tailing (IOT). Consistency and Strength test were conducted on both concrete specimens. It was observed that concrete workability reduced with increase in the percentage of iron ore tailing in the mix. Twenty-eight (28) days compressive strength and indirect tensile strength values of 43.67N/mm2 and 2.69N/mm2 respectively, were obtained for concrete when 20% iron ore tailing (IOT) was used, Values comparable to 28days compressive strength and indirect tensile strength values of 45.02N/mm2 and 2.64N/mm2 respectively, obtained using only sand as fine aggregate. Keywords: concrete; sand (RS); iron ore tailing (IOT); compressive and tensile strength.
