Average depth model has a variety of applications in hydraulic engineering,
especially in applications that flow depth is much smaller than the width of the flow.
In this method the vertical variation is negligible and the hydraulic variables
average integrated from channel bed to the surface free for the vertical axis. in
equations arising management, pure hydrostatic pressure is assumed that
not really valid in the case of flow in the bed is curved and can not be described
curvature effects of the bed.
The book is an edited collection of research articles covering the current state of sonar systems, the signal processing methods and their applications prepared by experts in the field. The first section is dedicated to the theory and applications of innovative synthetic aperture, interferometric, multistatic sonars and modeling and simulation.
This work inevitably sprang out of our environmental biotechnology modules at
the University of Durham, but it is not intended to be just another ‘book of the
course’. Though it is clearly rooted in these origins, it reflects our wider, and
rather varied, experiences of the field. In many respects, we have been fortunate;
teaching has undoubtedly drawn on the ‘theory’, while our own consultancy has
tended to focus us on the ‘application’.
A newcomer to the scene, aerobic granulation is on its way to becoming the hot new technology for high-efficiency wastewater treatment. Thus far, intensive research has been conducted with regard to the understanding of the mechanism of aerobic granulation in sequencing batch reactors (SBR) and its application in treating a wide variety of municipal and industrial wastewater. This basic research has promoted the technology from laboratory-study all the way to the present pilot- and full-scale application.
The rapid pace in which trace analysis is changing has warranted the writing of a
second edition in a relatively short period. What is new? The second edition attempts
to move the reader from the most elementary of principles of trace environmental
quantitative analysis (TEQA) to those techniques and applications currently being
practiced in analytical laboratories dedicated to trace environmental chemical and
trace environmental health quantitative analysis while adding new significant topics....
I have literally handled hundreds of customer calls which ranged through a wide gamut of difficulties and applications challenges. A great majority of these calls could have been avoided had the end user read just the first section of Mr. Broadwell's book'its appeal will span the gamut between the researcher and designing engineer to the actual day to day operator.
This book is written for marine structural engineers and naval architects, as well as mechanical
engineers and civil engineers who work on struch~ral design. The preparation of the book is
motivated by extensive use of the finite element analysis and dynamidfatigue analysis, fast paced
advances in computer and information technology, and application of risk and reliability methods.
Integrating ecotoxicological concepts across a range of hierarchical levels, Ecotoxicology: A Comprehensive Treatmentfocuses on the paradigms and fundamental themes of ecotoxicology while providing the detail and practical application of concepts often found in more specialized books.
Seventy-five percent of the world’s poor live in rural areas and most are involved
in agriculture. In the 21st century, agriculture remains fundamental to economic
growth, poverty alleviation, and environmental sustainability. The World Bank’s
Agriculture and Rural Development publication series presents recent analyses of
issues that affect the role of agriculture, including livestock, fisheries, and forestry,
as a source of economic development, rural livelihoods, and environmental services.
Words can easily borrow, but the meaning of love from the heart of a people is difficult to describe. So I want to ask for forgiveness from the people that support can not be appreciated in the words and from those who, by any chance, I forgot to mention.
First of all what I want to thank prof. dr.ir. Wind Herman and his wife - Joke. The interviews with prof. Wind held in Bangkok and his decision has helped me to be here, at the University of Twente, to carry out my doctoral research. Herman and Joke, I will never forget...
In some cases, the larger cells may be further distinguished based on their scattering
characteristics (coccolithophorids) or the presence of both PE and chlorophyll (cryptophytes)
(Olson et al., 1989; Collier & Campell, 1999).
Many authors have reported the distributions and dynamics of each photosynthetic group
in the water column in different marine environments (Li, 1995; Campbell & Vaulot, 1993;
Vaulot & Marie, 1999).
England’s fisheries in 1871, Congress created the U.S. Commission of Fish and Fisheries (Hobart 1995). The first appointed Commissioner, Spencer Baird, initiated marine ecological studies as one of his first priorities. According to Baird, our understanding of fish “... would not be complete without a thorough knowledge of their associates in the sea, especially of such as prey upon them or constitute their food....” He understood that the presence or absence of fish was related not only to removal by fishing, but also to the dynamics of physical and chemical oceanography.
This standard covers the design, construction, and location of liquefied petroleum gas (LPG) installations at marine and pipeline terminals, natural gas processing plants, refineries, petrochemical plants, or tank farms. This standard covers storage vessels, loading and unloading systems, piping, or and related equipment.
In conclusion, the results reported herewith show a significant relationship between
epifluorescence microscopy and flow cytometry, but coefficients of variation were
considerably lower for bacterial counts estimated by flow cytometry than epifluorescence
microscopy. Generally, the use of flow cytometry in marine microbiology reduces the
processing time of the sample and increases the number of processed samples.
I conceived of the courses that led to this book on sabbatical in
1999–2000, during my time as the Mote Eminent Scholar at Florida
State University and the Mote Marine Laboratory (a chair generously
funded by William R. Mote, who was a good friend of science). While at
FSU, I worked on a problem of life histories in fluctuating environments
with Joe Travis and we needed to construct log-normal random variables
of specified means and variances.
Over the past 25 years the discipline of ecotoxicology has undergone two
major developments. Firstly, new assays have been developed, deploying
organisms that bear added relevance to the specific environment under
investigation. Several new procedures assess the effects on organisms after
exposure to environmental samples rather than to spiked water or sediment
samples. Also noteworthy is the considerable attention given to effects of
chronic exposure to low levels of contaminants.
Tungsten Carbide - Processing and Applications, provides fundamental and practical information of tungsten carbide from powder processing to machining technologies for industry to explore more potential applications. Tungsten carbide has attracted great interest to both engineers and academics for the sake of its excellent properties such as hard and wear-resistance, high melting point and chemically inert. It has been applied in numerous important industries including aerospace, oil and gas, automotive, semiconductor and marine as mining and cutting tools, mould and die, wear parts, etc.
Available data suggest that, in addition to the obvious catches of fish for human needs, the by-
catches in the world’s fisheries have a significant ecological impact and cause mortality amongst fin-fish
(particularly the juveniles of commercial fish species), as well as amongst benthic invertebrates, marine
mammals, turtles and birds.
Commonly referred to as bivalves, are the class of marine and freshwater molluscs with laterally compressed bodies enclosed by a shell in two hinged parts. They include clams, oysters, mussels, scallops, and numerous other families
The changing presence of the Internet from a medium for elites to one in common use in our
everyday lives raises important questions about its impact on access to resources, social
interaction, and commitment to local community. This book brings together studies that cover
the impact of “the Internet” in everyday life in the United States, Canada, Britain, Germany,
India, Japan and globally. These studies show the Internet as a complex landscape of
applications, purposes and users.
