Disinfectant Decay and Corrosion: Laboratory and Field Studies (Paperback): F. Diganio, V Speight, W. Zhang Disinfectant Decay and Corrosion: Laboratory and Field Studies (Paperback)
F. Diganio, V Speight, W. Zhang
R2,798 Discovery Miles 27 980 Ships in 12 - 17 working days

The primary objective of this research was to develop and test a pipe-section reactor to measure the decay rate of disinfectant at the pipe wall. The pipe-section reactor is more convenient than pipe loop reactors which require a large laboratory and large supply volume of water. It is also a more realistic representation of the pipe surface than provided in pipe coupon experiments or annular reactors. The effects of water velocity and corrosion rate can be investigated using a pipe-section reactor, while still affording the simplicity of laboratory-scale, batch reactor operation. The secondary objective was to collect field data from two distribution systems in North Carolina (North Chatham County and Durham) to measure the decay of free chlorine by two alternative methods and to explore a relationship with corrosion rate. The ultimate goal would be to achieve a better understanding of disinfectant decay at the pipe walls such that a set of default values for decay rate coefficients could be specified for free chlorination and chloramination, the two most common secondary disinfectants.The pipe-section reactor consisted of a 20-inch (508 mm) length of either a six-inch (152 mm) diameter section of cast iron (CI) or cement-lined ductile iron (DI) pipe. An inner cylinder of Plexiglas was inserted to create a narrow annular space between pipe wall and the Plexiglas wall. A large, propeller-type stirrer was inserted into the inner cylinder to circulate water from the inner cylinder to the annular space. The water velocity adjacent to the pipe wall was controlled by the rotational speed of the stirrer motor; the velocity range was from about 0.5 to 2.0 ft/s (0.16 to 0.62 m/s). The pipe-section reactor can be operated in both continuous flow and batch modes of operation. In either mode, experiments can be designed easily to test different rate models for wall reactions. The reactor was filled with the tap water distributed by the Orange Water and Sewer Authority (OWASA) which on annual average is of very low alkalinity (3.1 mg/L as CaCO3) with a pH of 7.4 and a total organic carbon (TOC) of 3.2 mg/L. The average annual concentration of a phosphate-based corrosion inhibitor was 1.3 mg/L.Except in experiments in which dissolved oxygen (DO) was removed, the DO was between 7 and 8.5 mg/L in the test water within the reactor at the beginning of the experiment. The decay rate in bulk water was measured in independent experiments in which 2 L of OWASA tap water was placed in a 2-L clean glass bottle in a dark place at room temperature (21C). Sample volumes of 25 mL were withdrawn for each chlorine measurement, giving a total withdrawal of 200 to 300 mL in each rate test. The experiments with the CI pipe-section reactor measured the effects of initial chlorine concentration, water velocity, pH, Cl - and DO on the rate of chlorine decay. The same parameters with the exception of DO were investigated in a DI pipe-section reactor.

Lessons in Sustainable Development from Japan and South Korea (Hardcover): S. Hsu, M. Naoi, W. Zhang Lessons in Sustainable Development from Japan and South Korea (Hardcover)
S. Hsu, M. Naoi, W. Zhang
R2,026 Discovery Miles 20 260 Ships in 10 - 15 working days

Lessons in Sustainable Development from Japan and South Korea provides a concise overview of sustainable development in Japan and South Korea. Hsu, Naoi, and Zhang focus on environment, energy, health, technology, biodiversity, production, governance, well-being, livelihood, regulation, property rights, and minerals as indicators of sustainable development. Japan has greatly improved its environment since the industrialization process ended in the 1970s. The nation also has excellent health care and transportation systems. However, Japan continues to struggle with gender inequality and traffic congestion. Poverty and inequality have remained challenges since the 1990s. Similarly, South Korea is continuing to improve its environment, as well as its health care system, but struggles with gender inequality, poverty, and inequality. The countries can benefit from better social policies, as well as from a partnership in improving energy self-sufficiency, including enhancement of renewable energy technologies.

R5,019 Discovery Miles 50 190 Ships in 10 - 15 working days

The emergence of a new macro economy in Euro-Asia is a great challenge for academics and policy makers alike. Our book focuses on this macro economy and the monetary and fiscal policy responses. As the new environment has evolved over time, private behaviour as well as policy responses have changed. Policy makers as well as private agents had to learn the new environment. In our book we thus put heavy emphasis on uncertainty and learning. The first part of the book explores monetary policies allowing for uncertainty and time-varying behaviour of economic agents in markets, in particular in the labour market and the monetary policy responses to it. We study both forward and backward looking behaviour, learning and robust control as well as the role of financial markets for policies. The second part explores fiscal policy in the Euro-area, its sustainability, its effects on economic growth and the attempts of the Euro-area to stabilize the public debt. The third part explores monetary and fiscal policy interactions in the Euro-area countries. Since there are many national fiscal authorities but only one monetary authority this is a particularly challenging problem of Euro-area countries. Methodologically, we use modern methods such as advanced econometric methodology, learning models that allows to study time varying behaviour, and dynamic macro modelling and dynamic optimization.

W. Zhang
R3,536 Discovery Miles 35 360 Ships in 12 - 17 working days

Microarray technology provides researchers in the life sciences with a revolutionary tool for measuring gene expression. However, this highly developed process involves multiple steps, from sample selection to data analysis, each susceptible to potentially costly errors. Without sound quality control, experimental microarrays may produce useless or, even worse, misleading results.

Microarray Quality Control provides a comprehensive resource for ensuring quality control in every step of this complex process. From experimental design to data processing, analysis, and interpretation, the emphasis in this text remains on practical advice for each stage of planning and running a microarray study. Chapters cover:

  • Quality of biological samples
  • Quality of DNA
  • Hybridization protocols Scanning
  • Data acquisition
  • Image analysis
  • Data analysis

Written for the broad group of workers-biologists, mathematicians, statisticians, engineers, physicians, and computational scientists-involved in microarray studies, Microarray Quality Control features a straightforward style easily accessed by various disciplines. Useful checklists and tips help ensure the integrity of results, and each chapter contains a thorough review of pertinent literature.

The only complete, systematic treatment of the topic available, Microarray Quality Control offers students and practitioners an invaluable resource for improving experimental quality and efficiency.
