Microbial Enhancement of Oil Recovery - Recent Advances
1st Edition
Volume 31
E.C. Donaldson
English
This conference was instituted to examine field activities in Microbial Enhancement of Oil Recovery. The U.S. Department of Energy has sponsored several field projects and the details from some of these were presented, as well as a few from industry. The balance of the program was concerned with new developments in research.Today's oil production technology leaves one third to one half of the original oil in place in the reservoir at abandonment of secondary recovery (waterflooding). This leaves a very large target for microbial enhanced oil recovery which was shown by the research papers of this conference to be capable of producing up to 50% of the residual oil. The field trials show that the normal projected oil production decline curve can be reversed, or leveled off by microbial enhancement of oil recovery.This conference has shown that a variety of applications are possible to correct oilfield problems as well as to enhance oil recovery. Among these is the suppression of hydrogen sulfide production which alone is a tremendous advance because of the large quantity of sour oil production. If hydrogen sulfide production can be curtailed it would increase the value of the produced oil, decrease it toxicity, and largely decrease it corrosiveness. All of these would be welcome both in the field and at the petroleum refinery where special precautions must be taken to process sour crude oil.Another very important discovery is the ability of certain bacteria to eliminate paraffin deposition around the producing well and in the tubulars. This is a welcome improvement for many producers who have considerable difficulty in controlling paraffin deposition.

The Prefrontal Cortex: Its Structure, Function and Pathology
1st Edition
Volume 85
J.P.C. de Bruin + 4 more
English
Thanks to a resurgence of interest and a recent proliferation of research techniques, much new and illuminating data has emerged during the last decade relating to the prefrontal cortex, particularly in primates and rodents. In view of this progress, the 16th International Summer School of Brain Research was held in Amsterdam, The Netherlands from 28 August to 1 September 1989, devoted to the topic of `The Prefrontal Cortex: Its Structure, Function and Pathology'.The edited proceedings, embodied in this 85th volume of `Progress in Brain Research', fall into three sections - the first of which, following two introductory chapters, discusses the present knowledge of the organization of prefrontal cortical systems. In the second section, developmental and plasticity aspects in rodent and human cortex are considered, whilst the third section deals extensively with the functional aspects characteristic for the prefrontal cortex in primates, rats and rabbits. The last section reviews several topics on dysfunction of prefrontal cortex in rat and man, including a historical review on psychosurgery.
Water Resources Development in Developing Countries
1st Edition
Volume 41
M.S. Peterson + 1 more
English
Water resources exploitation has been regarded as a way of initiating economic development in many countries. Planning concepts are now changing. Thorough environmental studies, sociological and economic studies now preceed project formulation. Justification solely on the basis of benefit cost studies is no longer sufficient for many development agencies. The broader approach is introduced in this book, but the real emphasis is on the situation in and needs of developing countries.Some of the problems experienced in building water resources in developing countries are described in this book, and methods of solution based on the limited experience of the authors, are offered. These range from use of unbiased common sense, coupled with a close understanding of people's requirements, to a comprehensive computer simulated planning model. Some types of water resources development are described in more detail. These include irrigation, hydro electric power and rural water supply. Sections on socio-economics and human resource development are also included, as well as on data collection, and project planning. Lessons from the failure of multimillion dollar projects are not hard to come by, and examples and pointers which will assist future planners are given. Attention is paid to the need for aid to include training and to stimulate local economies. However big water projects appear, they cannot escape the effects of the rest of the country's economy. Attention is also drawn to environmental problems, particularly soil erosion, often caused by water resources development. The fact that water resources development cannot be carried out by engineers only, is recognized. The input of many professions, and vast experience, is needed. Drawn on international case studies, much of the material has been presented in postgraduate courses by the authors.
Introduction to Zeolite Science and Practice
1st Edition
Volume 58
E.M. Flanigen + 2 more
English
Zeolites and related molecular sieves have quickly become important pathways to new opportunities in the fields of oil processing and petrochemical synthesis. The signs of intense activity in both industry and academia are evident: burgeoning papers and patent applications; increasing numbers of industrial zeolite-based processes and their rapid expansion into organic chemicals manufacturing; recent progress in zeolite accessibility range, matrix behaviour, lattice components and satellite structures; and the recognition that zeolites, which are stable and can be regenerated, may be incorporated into new, environmentally friendly processes. This volume offers a thorough, up-to-date introduction to zeolites and such related materials as crystalline aluminium phosphates and clays. Its 16 chapters, each written by specialists, provide detailed treatments of zeolite theory (including a review of major developments), zeolite laboratory and research practice, and zeolite industry applications. Students and individuals entering the field will find Introduction to Zeolite Science and Practice a thorough guidebook. Experienced researchers will appreciate its in-depth coverage of the zeolite spectrum, including the latest views on zeolite structure, characterization and applications.
Heat Transfer with Freezing and Thawing
1st Edition
Volume 65
V.J. Lunardini
English
This volume provides a comprehensive overview on the vast amount of literature on solidification heat transfer. Chapter one develops important basic equations and discusses the validity of considering only conductive heat transfer, while ignoring convection, in the large class of materials which make up the porous media. Chapters 2 to 4 deal with problems that can be expressed in plane (Cartesian) coordinates. These problems are further divided into boundary conditions of temperature, prescribed heat flux, and surface convection. Chapter 5 examines some plane geometries involving three-dimensional freezing or thawing. Problems in the cylindrical and spherical coordinate systems are covered in chapters 6 and 7. Chapter 8 is an introduction to solidification in porous media.Many of the applications have been directed to water/ice soil-systems, but it should be clear that the basic techniques and solutions can be applied to such diverse areas as metallurgy, biological systems, latent heat storage, and the preservation of food.
Agricultural Economics and Policy: International Challenges for the Nineties
Essays in Honour of Prof. Jan de Veer
1st Edition
Volume 7
K. Burger + 3 more
English
International challenges in agricultural economics for the nineties will come from a redirection of the EC policy, stimulated by GATT negotiations, the opening towards Eastern Europe and environmental considerations, from a production oriented policy towards rural policy, aiming at protecting vulnerable regions, maintaining a rural population, curtailing production in the West and fostering it in the East, and aiming at the provision of environmentally desirable output.This book focusses on developments that are bound to dominate the discussion of agricultural economics and policy in the years to come. Together, the contributions give a vivid picture of the dynamic times that lie ahead for both Eastern and Western European agriculture, and of the profound changes that will be forced upon agricultural policy.

Evaluation of Environmental Data for Regulatory and Impact Assessment
1st Edition
Volume 41
S. Ramamoorthy + 1 more
English
Mounting concern for the state of the environment has led to a substantial increase in the collection of environmental data in the past two decades. This trend raises issues with regard to the quality assurance and quality control of the data gathering process, from sampling to analysis. The evaluation of environmental data in terms of quality, and relevance for use in the management of toxic chemicals in the enviroment, has reached a critical phase. An enormous volume of data is being generated, on both residue levels and their effects, to meet short- and long-term needs for regulatory procedures and (environmental) impact assessments. Therefore, it is important to verify not only the quality of the data collected, but also the choice of relevant test parameters. This volume deals with the evolution of analytical methodologies to the current state-of-the-art techniques, quality assurance/quality control of data acquirements, and testing procedures for screening of toxic chemicals - including their hazard identification, persistence, and fate processes in the environment. The models currently employed in environmental impact assessment and risk assessment are also discussed in detail. Public involvement and participation in regulatory decision-making processess is also described. It is intended for managers and scientists involved in environmental management and research of toxic chemicals in the environment.
