This book presents a case study on a new approach for the optimum design of rooftop, grid-connected photovoltaic-system installation. The study includes two scenarios using different brands of commercially available PV modules and inverters. It investigates and compares several different rooftop grid-connected PV-system configurations taking into account PV modules and inverter specifications. The book also discusses the detailed dynamic MATLAB/Simulink model of the proposed rooftop grid-connected PV system, and uses this model to estimate the energy production capabilities, cost of energy (COE), simple payback time (SPBT) and greenhouse gas (GHG) emissions for each configuration. The book then presents a comprehensive small signal MATLAB/Simulink model for the DC-DC converter operated under continuous conduction mode (CCM). First, the buck converter is modeled using state-space average model and dynamic equations, depicting the converter, are derived. Then a detailed MATLAB/Simulink model utilizing SimElectronics (R) Toolbox is developed. Lastly, the robustness of the converter model is verified against input voltage variations and step load changes.

One of the early set of reforms that South Africa embarked on after emerging from apartheid was in the water sector, following a remarkable, consultative process. The policy and legal reforms were comprehensive and covered almost all aspects of water management including revolutionary changes in defining and allocating rights to water, radical reforms in water management and supply institutions, the introduction of the protection of environmental flows, and major shifts in charging for water use and in the provision of free basic water. Over ten years of implementation of these policy and legislative changes mean that valu-able lessons have already been learned and useful experiences gained in the challenge of effective water resources management and water services provision in a middle income country.

Offering a cross-country examination and comparison of drought awareness and experience, this book shows how scientists, water managers, and policy makers approach drought and water scarcity in arid and semi-arid regions of Spain, Mexico, Australia, South Africa and the United States.

Leaving aside human and social capital for a future volume, the book should be viewed as a crucial first step in developing indicators for total wealth in the countries covered by the case studies, which include Kenya, Uganda, Tanzania, Ethiopia, Mozambique and South Africa. These case studies experiment with implementing the SEAA in sub-Saharan nations known to suffer from the 'resource curse': their wealth in resources and commodities has allowed inflows of liquidity, yet this cash has not funded crucial developments in infrastructure or education. What's more, resource-driven economies are highly vulnerable to commodity price mutability. The new measures of wealth deployed here offer more hope for the future in these countries than they themselves would once have allowed for.

Thermofluid Modeling for Sustainable Energy Applications provides a collection of the most recent, cutting-edge developments in the application of fluid mechanics modeling to energy systems and energy efficient technology. Each chapter introduces relevant theories alongside detailed, real-life case studies that demonstrate the value of thermofluid modeling and simulation as an integral part of the engineering process. Research problems and modeling solutions across a range of energy efficiency scenarios are presented by experts, helping users build a sustainable engineering knowledge base. The text offers novel examples of the use of computation fluid dynamics in relation to hot topics, including passive air cooling and thermal storage. It is a valuable resource for academics, engineers, and students undertaking research in thermal engineering.

The Qattara Depression is part of the Northwestern Desert in Egypt and is home to the second lowest point in Africa at -133 meters below sea level. Therefore, before any projects can be carried out in this area, we must first understand the geology of the land. The present study deals with the high-resolution sequence stratigraphic analysis of the Lower Miocene Moghra Formation outcrops in the Qattara Depression Region. The literature on the sedimentology and sequence stratigraphy of the Moghra Formation has been sparse to date, despite some excellent work over the years by academic and petroleum workers. Moreover, the area studied is within what was once a front-line of World War II, where mine fields and war relics are scattered and cover wide reaches. This has resulted in limited geologic mapping in the past. Thus, great attention is paid in this study to establishing a robust sedimentology and high-resolution sequence stratigraphic framework for the Lower Miocene Moghra Formation. Included are works based on outcrops and, most importantly, new sedimentological and chronostratigraphic information not previously available.

This Medical Instrumentation handbook establishes an easy approach for the students going through their studies in Medical Laboratory Technology. This handbook describes the principles, applications, and design of the medical instruments most commonly used in laboratory, because equipment changes with time, we have stressed fundamental principles of operation and general types of equipment, avoiding detailed descriptions and photographs of specific models. Furthermore, because Medical Technology is an interdisciplinary field requiring good communication with health-care personnel, we have provided some applications for each type of instrument. Medical laboratories play a major role in the diagnosis, treatment, prognosis and monitoring of diseases. Moreover it contains in-depth information about the structure and function of each part of Laboratory instruments. In short the aim of this book is to provide a meaningful and comprehensive picture of Medical Instruments including Microscope, Autoclave, PCR, Electrophoresis, Chromatography, Ovens, Blood Gas Analyzers and many other basic instruments of Medical Laboratory.
