Controlled Release, Biochemical Effects of Pesticides, Inhibition of Plant Pathogenic Fungi (Chemistry of Plant Protection #6)

by Mufit Bahadir Peter Böger Heinrich Buchenauer Morifusa Eto Mohammed A.Q. Khan Gerd Pfister Gerhard Sandmann

Since the middle of the Sixties, new types of formulation for biologically active com­ pounds have been developed, which have been introduced into the literature under the term Controlled Release Formulations (CRF). Stimulated by results from former and successful pharmaceutical research, which was engaged in the production of prepa­ rations with protracted effects (introduction onto the market in the year 1952 of D­ amphetamine in the form of pellets, coated to varying degrees with fats and waxes) 1), experiments were carried out to transfer the prolongation of effectiveness to pesticidal substances also, by means of a depot formulation. Initial work was concerned with the production of protective coatings for sonar systems in marine ecosystems. By means of antifouling paints or rubber coatings containing tri-n-butyl-tin oxide (TBTO), the growth of marine organisms on sonar domes, buoys and hulls in the water could be effectively prevented 2. 3). Controlled release formUlations of pesticides are defined as depot systems which continuously release their toxic constituents into the environment over a specified period of time (usually months to years) 4). According to this definition, such formu­ lations can be successfully employed where a chronic exposure to biologically active compounds is required over a longer period. The following hypothetical example is intended to illustrate this 5). In Fig. 1, the duration of activity of a non-persistent pesticide with a loss rate under environmental conditions of t1/2 = 15 days, is graphically illustrated.

Controlling Asbestos in Buildings: An Economic Investigation (Routledge Revivals)

by Donald N. Dewees

Asbestos dust is well-known for causing cancer and other life-threatening illnesses yet still contaminates countless schools, factories and office buildings. This raises the issue of the best way to deal with Asbestos; immediate removal, containment or removal at renovation or demolition. Originally published in 1986, this report aims to evaluate these methods of dealing with asbestos in relation to their cost-effectiveness to conclude the most appropriate solution. This title will be of interest to students of Environmental Studies and Economics.

Controlling Differential Settlement of Highway Soft Soil Subgrade: A New Method and Its Engineering Applications (SpringerBriefs in Applied Sciences and Technology)

by Hanhua Zhu Zhijun Wu Mengchong Chen Yongli Zhao

Drawing on years of practical on-site experience, this book presents a new method for controlling "bridge-head bumping" in soft soil ground. Based on deformation compatibility and control theory of structure, it proposes strategies for improving the design method of soft soil ground and the effective "bridge-head bumping" control method. Soft soil ground is chiefly characterized by a large void ratio, high compressibility, high water content, low impermeability, low strength, strong structure and high sensitivity. As a result, it has pronounced rheological properties, and controlling "bridge-head bumping" in soft soil ground is essential to control the amount of soil rheology-induced unstable successive settlement. The book offers extensive information on this and related topics, making it a valuable guide for engineers in Civil Engineering and Geotechnical Engineering alike.

Controlling International Shipping and Aviation Emissions: Governing the Global Climate Crisis (Routledge Research in Global Environmental Governance)

by David A. Deese

This book assesses the extent to which two specialized UN agencies- the International Maritime Organization (IMO) in London and the International Civil Aviation Organization (ICAO) in Montreal - have been able to regulate environmental pollution in the global commons. Since the Kyoto Protocol and its tasking of these two International Organisations (IOs) in 1997 to regulate greenhouse gas emissions from the fast-growing international shipping and aviation sectors, they have struggled with the assignment even as the external pressure has mounted for them to act. David Deese examines why these two UN agencies have largely failed to execute their critical missions to date and explores the most promising emerging and feasible routes to control and reduce these emissions by other means. Drawing on a range of sources including interviews with key actors in the IMO and ICAO, as well as from industry and national governments, Deese looks at the multifaceted politics that drive these IOs and considers how this has delayed and frustrated the execution of their assigned climate mitigation missions. He also explains how the limitations of the IMO and ICAO are likely to be found to a degree in other UN specialized agencies and examines how lessons learned here will be helpful in understanding the operations of other IOs. The book will be of great interest to students and scholars of global governance and international organisations, transport and environment and climate change. It will also be a useful resource for industry and non-profit experts and public officials working in shipping and aviation regulation.

The Controversy over Marine Protected Areas: Science meets Policy (SpringerBriefs in Environmental Science #0)

by Alex Caveen Nick Polunin Tim Gray Selina Marguerite Stead

This book is a critical analysis of the concept of marine protected areas (MPAs) particularly as a tool for marine resource management. It explains the reasons for the extraordinary rise of MPAs to the top of the political agenda for marine policy, and evaluates the scientific credentials for the unprecedented popularity of this management option. The book reveals the role played by two policy networks – epistemic community and advocacy coalition – in promoting the notion of MPA, showing how advocacy for marine reserves by some scientists based on limited evidence of fisheries benefits has led to a blurring of the boundary between science and politics. Second, the study investigates whether the scientific consensus on MPAs has resulted in a publication bias, whereby pro-MPA articles are given preferential treatment by peer-reviewed academic journals, though it found only limited evidence of such a bias. Third, the project conducts a systematic review of the literature to determine the ecological effects of MPAs, and reaches the conclusion that there is little proof of a positive impact on finfish populations in temperate waters. Fourth, the study uses discourse analysis to trace the effects of a public campaigning policy network on marine conservation zones (MCZs) in England, which demonstrated that there was considerable confusion over the objectives that MCZs were being designated to achieve. The book’s conclusion is that the MPA issue shows the power of ideas in marine governance, but offers a caution that scientists who cross the line between science and politics risk exaggerating the benefits of MPAs by glossing over uncertainties in the data, which may antagonise the fishing industry, delay resolution of the MPA issue, and weaken public faith in marine science if and when the benefits of MCZs are subsequently seen to be limited.

Convection and Substorms: Paradigms of Magnetospheric Phenomenology (International Series on Astronomy and Astrophysics)

by Charles F. Kennel

The magnetosphere is the region where cosmic rays and the solar wind interact with the Earth's magnetic field, creating such phenomena as the northern lights and other aurorae. The configuration and dynamics of the magnetosphere are of interest to planetary physicists, geophysicists, plasma astrophysicists, and to scientists planning space missions. The circulation of solar wind plasma in the magnetosphere and substorms have long been used as the principle paradigms for studying this vital region. Charles F. Kennel, a leading scientist in the field, here presents a synthesis of the convection and substorm literatures, and an analysis of convection and substorm interactions; he also suggests that the currently accepted steady reconnection model may be advantageously replaced by a model of multiple tail reconnection events, in which many mutually interdependent reconnections occur. Written in an accessible, non-mathematical style, this book introduces the reader to the exciting discoveries in this fast-growing field.

Convection in Ferro-Nanofluids: Physical Mechanisms, Flow Patterns, and Heat Transfer (Advances in Mechanics and Mathematics #40)

by Aleksandra A. Bozhko Sergey A. Suslov

This book covers the experimental and theoretical study of convection in non-isothermal ferro-nanofluids (FNFs). Since FNFs are not transparent and magnetic fields are very sensitive to the shape of the boundary between magnetic and nonmagnetic media, special flow visualization techniques based on the use of thermo-sensitive liquid crystal films, infrared cameras, as well as local and integral temperature sensors are discussed in the book. This book considers several major configurations of convective chambers and the applied magnetic field. For each of them, the stability boundaries are determined theoretically and experimentally. The physical types of dominant instabilities and the characteristics of their interactions are subsequently established using linear and weakly non-linear hydrodynamic stability analyses and elements of bifurcation theory. The book also discusses the potential of using magnetically controlled ferro-nanofluids as a heat carrier in situations where heat removal by natural convection is not possible due to the lack of gravity (orbital stations) or extreme confinement (microelectronics). Researchers and practitioners working in the areas of fluid mechanics, hydrodynamic stability, and heat and mass transfer will benefit from this book.

Convection in Rotating Fluids (Fluid Mechanics and Its Applications #29)

by B.M. Boubnov Georgi S. Golitsyn

Spatial inhomogeneity of heating of fluids in the gravity field is the cause of all motions in nature: in the atmosphere and the oceans on Earth, in astrophysical and planetary objects. All natural objects rotate and convective motions in rotating fluids are of interest in many geophysical and astrophysical phenomena. In many industrial applications, too (crystal growth, semiconductor manufacturing), heating and rotation are the main mechanisms defining the structure and quality of the material. Depending on the geometry of the systems and the mutual orientation of temperature and gravity field, a variety of phenomena will arise in rotating fluids, such as regular and oscillating waves, intensive solitary vortices and regular vortex grids, interacting vortices and turbulent mixing. In this book the authors elucidate the physical essence of these phenomena, determining and classifying flow regimes in the space of similarity numbers. The theoretical and computational results are presented only when the results help to explain basic qualitative motion characteristics. The book will be of interest to researchers and graduate students in fluid mechanics, meteorology, oceanography and astrophysics, crystallography, heat and mass transfer.

Convective Heat and Mass Transfer in Porous Media (NATO Science Series E: #196)

by Sadik Kakaç Birol Kilkis Frank A. Kulacki Faruk Annç

The rapid growth of literature on convective heat and mass transfer through porous media has brought both engineering and fundamental knowledge to a new state of completeness and depth. Additionally, several new questions of fundamental merit have arisen in several areas which bear direct relation to further advancement of basic knowledge and applications in this field. For example, the growth of fundamental heat transfer data and correlations for engineering use for saturated media has now reached the point where the relations for heat transfer coefficients and flow parameters are known well enough for design purposes. Multiple flow field regimes in natural convection have been identified in several important enclosure geometries. New questions have arisen on the nature of equations being used in theoretical studies, i. e. , the Validity of Darcy assumption is being brought into question; Wall effects in high and low velocity flow fields have been found to play a role in predicting transport coefficients; The formulation of transport problems in fractured media are being investigated as both an extension of those in a homogeneous medium and for application in engineering systems in geologic media and problems on saturated media are being addressed to determine their proper formulation and solution. The long standing problem of how to adequately formulate and solve problems of multi-phase heat and mass transfer in heterogeneous media is important in the technologies of chemical reactor engineering and enhanced oil recovery.

Convergence: An Architectural Agenda For Energy

by Kiel Moe

Convergence is based on the thermodynamic premise that architecture should maximize its ecological and architectural power. No matter how paradoxical it might initially seem, architects should maximize energy intake, maximize energy use, and maximize energy feedback and reinforcement. This presumes that the necessary excess of architecture is in fact an architect’s greatest asset when it comes to an agenda for energy, not a liability. But how do we start to understand the full range of eco-thermodynamic principles which need to be engaged with in order to achieve this? Kiel Moe explicates three factors: materials, energy systems and amortization. When these three factors converge through design, the resulting buildings begin to perform in complex, if not subtle, ways. By drawing on a range of architectural, thermodynamic, and ecological sources as well as illustrated and well-designed case studies, the author shows what architecture stands to gain by simultaneously maximizing the architectural and ecological power of buildings. .

Convergence and Developmental Aspects of Credit Allocations in BRICS Nations: Theoretical and Empirical Inquiries

by Ramesh Chandra Das

This book explores the levels of cooperation and the phenomenon of convergence among BRICS nations. It provides an in-depth look into the financial and banking systems among these rapidly developing economies and the steps they have taken to foster development and counter inequalities.Of the many factors in determining the income and wealth of a country as well as a group of countries, commercial bank credit, a well-known financial indicator, has been an important one. This book analyses the governance and structure of the New Development Bank and its effects on group members for peer growth and to defend against any external economic and political shocks. It looks at how much of an influence the commercial bank credit, or simply the credit, has upon the income levels of the BRICS member countries, how equitable they are, whether they are converging in credits and incomes, and other such issues. It also focuses on India’s credit aspects of inclusiveness and convergence.With a strong empirical model estimation, this book will be of interest to students and researchers of economics, finance, management, political studies, international relations, and international trade.

Convergence Clubs and Spatial Externalities: Models and Applications of Regional Convergence in Europe (Advances in Spatial Science)

by Stilianos Alexiadis

Do dynamic externalities, in the form of technology creation, adoption and spatial agglomeration shape the pattern of regional growth in Europe? This study provides an alternative view on regional convergence. A model is developed which attributes club-convergence to existing differences with respect to the degree of technology adoption. In the first instance, empirical results suggest that the NUTS-2 regions of the EU-27 converge at a very slow rate. Further tests, however, indicate that convergence is restricted to a specific subset of regions. Such conclusions are tested further, using an alternative model of club-convergence, which incorporates the impact of spatial interaction, agglomeration externalities and technology. This shows that the convergence-club in Europe follows a certain geographical pattern and all members share similar characteristics regarding technology creation and adoption, and agglomeration externalities. ​

Convergence-Confinement Method for Tunnel Design (Springer Tracts in Civil Engineering)

by Jean Sulem Marc Panet

This book presents the theoretical bases and the application tools for using the 'convergence-confinement' method which is a rational method largely used in design engineering for tunneling. Until recently, the stability conditions of underground works and the choice of support methods were essentially defined on the basis of good practice or empirical methods. The progress made, on one hand on the knowledge of the constitutive laws of soils and rocks and, on the other hand on the numerical modeling of the interaction between the ground and the structures have led to the development of robust design tools for tunnels supports. The convergence-confinement method makes it possible to simulate the excavation of a tunnel and the installation of the support using a simple plane strain model. The book presents the theoretical bases of the method and its most recent developments. Closed-form solutions for stress and displacement fields around tunnels are provided for elastic, viscoelastic and elasto-plastic behavior of the ground. More generally, the principles for applying the method in numerical models are presented.

Convergent Leadership-Divergent Exposures: Climate Change, Resilience, Vulnerabilities, and Ethics

by Franco Oboni Cesar H. Oboni

This book aims, through its chapters, at providing the knowledge to make competent decisions, convince peers or top management to take appropriate action, or beat out the competition for climate adaptation measures including adjustments for design and operations. Topics discussed include business-as-usual vs. divergence; the effects of public pressure on corporate, industrial and government decision making; techniques for gathering the proper information to assess risks and hazards; the importance determining risk tolerance thresholds; the difference between tolerable risks, intolerable ones that benefit from mitigation and those that require strategic shifts; why common practice approaches such as FMEA, and risk matrices are inadequate in today’s world and do not help ensure infrastructural and systemic resilience and sustainability.Case histories and three complete case studies that can be adapted to any industry or project walk the reader step by step from client request to recommendations and conditions of validity. The ultimate aim is to understand how to reduce risks to tolerable and societally acceptable levels while simultaneously creating sustainable and ethical systems.
