The Routes of Man: How Roads are Changing the W...

Roads bind our world—metaphorically and literally—transforming landscapes and the lives of the people who inhabit them. Roads have unparalleled power to impact communities, unite worlds and sunder them, and reveal the hopes and fears of those who travel them.With his marvelous eye for detail and his contagious enthusiasm, Ted Conover explores six of these key byways worldwide. In Peru, he traces the journey of a load of rare mahogany over the Andes to its origin, an untracked part of the Amazon basin soon to be traversed by a new east-west route across South America. In East Africa, he visits truckers whose travels have been linked to the worldwide spread of AIDS. In the West Bank, he monitors highway checkpoints with Israeli soldiers and then passes through them with Palestinians, witnessing the injustices and danger borne by both sides. He shuffles down a frozen riverbed with teenagers escaping their Himalayan valley to see how a new road will affect the now-isolated Indian region of Ladakh. From the passenger seat of a new Hyundai piling up the miles, he describes the exuberant upsurge in car culture as highways proliferate across China. And from inside an ambulance, he offers an apocalyptic but precise vision of Lagos, Nigeria, where congestion and chaos on freeways signal the rise of the global megacity.A spirited, urgent book that reveals the costs and benefits of being connected—how, from ancient Rome to the present, roads have played a crucial role in human life, advancing civilization even as they set it back. 1.

Various governmental and non governmental efforts are being exerted to combat the HIV/AIDS pandemic by sentinel surveys. Unfortunately, there has not been any organized survey in Nigeria to extensively determine the opportunistic infections associated with HIV/AIDS. This book therefore, highlights specifically on some pulmonary bacterial and fungal opportunistic infections in Kano metropolis, the isolation and identification of opportunistic bacterial and fungal agents causing pulmonary infections, the relationships between pulmonary opportunistic pathogens and CD4 count and immune status and viral load of HIV positive clients. This will contribute towards management and care of AIDS clients and will provide the need for monitoring by health care facilities and related agencies.

Sustainable Sediment Management

Sedimentation is a significant natural phenomenon affecting hydro power reservoirs. Apart from major watershed problems such as loss of soil fertility and productivity caused by soil erosion, increased sediment load associated with erosion processes reduces the storage capacity and shortens the useful life of reservoirs. In view of this, an investigation of the hydrological processes and sediment transport mechanism at the upstream catchments of hydro power reservoirs is critical to the sustainable operations of hydro power dams. This book therefore provides a detailed sediment management modelling procedure using the Soil and Water Assessment Tool (SWAT) interfaced with Mapwindow-GIS to simulate the hydrology, predict the sediment yield and identify erosion prone areas of a watershed upstream of Jebba Reservoir in Nigeria. Four sediment management scenarios were considered while cost implications of different management scenarios were also examined. This book can be useful to professionals in Water Resources Engineering, Lecturers,graduate and postgraduate students and other individuals interested in the area of sustainable management of water and sediments in a watershed

Purifying Ability of a Constructed Solar Still ...

This book discusses the comparative performance of a locally constructed basin type single plate solar still with a refill and a standard electronic distiller unit (AQUATRON C72-8010 MODEL A4000). The still was used in Girei, North Eastern Nigeria, for the production of clean water for human consumption and other hygenic uses such as in hospitals and pharmaceuticals. The still utilizes solar energy and some environmental factors like wind speed and ambient temperature. A well water sample was collected in sterile Jerry can from Girei town, and fed into both the constructed still and the Electronic still. Enumerations of aerobic contaminants, coliform bacteria, pH value and iron II (Fe2+) were noted both before and after the distillation. The sample was heavily contaminated with an average microbial load of 30000 cfu/ml, 100% distribution of coliform bacteria and 260 mg/L calcium carbonate CaCO3. The analysis on the distillates indicated that all these were removed completely. The cumulative yield collected from the constructed still per day is 3.6 L and the still has a thermal efficiency of 26% on a clear summer day.

The evaluation of community- directed treatment with ivermectin (CDTI) was carried out in Abia State, Nigeria from February 2009 to November 2011, to assess the progress of the programme which has lasted for over a decade. Abia State is made up of 17 Local Government Areas, eight of which are endemic for onchocerciasis (2 hyper-endemic and 6 meso- endemic LGAs) according to REMO assessment. The survey involved the collection of data from the different levels that participate in the collection and distribution of ivermectin. Ten indicators that promote sustainability were used, grouped under activities and processes which support CDTI, resources provided and results achieved. To ascertain the level of progress, the survey also carried out some aspects of disease containment using skin snipping method to determine the community microfilarial load. A study questionnaire was designed and administered to ascertain the knowledge of the people on the drug, its perceived efficacy, compliance rate and the willingness of the community members to sustain the treatment programme. The study population involved both high and low compliers groups. The result obtained revealed that Abia State CDTI

Smart Materials in Reinforced Concrete Bridges

Earthquakes constitute a major problem for mankind resulting in loss of lives and structures. Though, Nigeria is not situated where major seismic activities are observed in the world, the country has experienced pockets of tremors comprising magnitudes ranging from 4.3 to 4.5. Smart structural materials suppress the structural vibration in a structure by adjusting the dynamic performance of the structure. One of such materials is the Shape Memory Alloy (SMA). SMA rods are unique for their shape memory effect and superelasticity and have been used as structural reinforcement for earthquake retrofits. This book focused on investigating the appropriate percentage of shape memory alloy and steel reinforcements for the least deflection in the column-capping beam of a 3-span composite bridge subjected to seismic load using finite element method with the aid of SAP2000 software. Five different earthquake scenarios (including Newhall Accelerogram) were used to obtain the best combination of steel and SMA reinforcement in the columns and capping beam for the best resistance to the Earthquake response.

This book x-rays the food safety condition of raw and ready-to-eat (RTE) beef, fish, and poultry in a major city in southern Nigeria with the view to compare it with standard microbiological benchmarks available worldwide. It also focuses on the microbiological quality of some abattoirs. In addition antibiotics sensitivity profile was determined for organisms detected. Recommendations for improvement to reduce microbial load especially on RTE food are also outlined.

In Nigeria, economic tree species in natural forests have suffered progressive depletion from over-exploitation. This necessitates seeking alternatives from lesser-used species (LUS). This book is a study on the wood properties of Ficus mucuso a LUS. The property variations axially and radially within the tree were also presented.Random sampling survey was conducted in Ibadan using structured questionnaire to establish the status of LUS and the species investigated. Five matured trees of Ficus mucuso a LUS were randomly selected and felled from Onigambari Forest Reserve. Samples were obtained at axial heights 10%, 25%, 50% and 75% of tree bole and further partitioned into corewood, middlewood and outerwood. Physical, mechanical, anatomical, chemical and machining properties of the specimens were determined in accordance with ASTM (1991) and BS373 (1983) standard methods. Results showed that Ficus mucuso wood is of low strength when compared with structural grade woods. It may however be utilized for items subjected to low-to-medium load applications such as light cabinet, chair frames, plywood, veneer and composite production.
