    • English
    Biology of Insect Eggs is a three-volume account of the biology of insect eggs and covers topics ranging from oviposition and respiratory systems to the respiratory efficiency of egg plastrons. Hydropyles and water relations are also discussed, along with colleterial glands, enemies of insect eggs, and devices used by insects to defend their eggs against enemies. The first volume of this book begins with an overview of a number of controversial points related to insect eggs, such as size of eggs, the kinds of metamorphosis, apolysis and ecdysis, and arrangement of orders of insects. The second volume contains chapters that deal with the structure of the female reproductive system; vitellogenesis; and the development of the micropylar complex. It also provides an account of the eggs of each order of insects, including Ephemeroptera, Orthoptera, and Cheleutoptera as well as Phthiraptera, Hemiptera, and Coleoptera. The third volume is the index to subjects, species, and the bibliography which contains more than 4,000 entries. This monograph will be of interest to biologists and entomologists.

  • Wind Engineering

    Proceedings of the Fifth International Conference, Fort Collins, Colorado, USA, July 1979
    • 1st Edition
    • J. E. Cermak
    • English
    Wind Engineering is a compendium of papers from the Fifth International Conference on Wind Engineering held in Colorado, USA, on July 8-14, 1979. Papers discuss the social and economic impact of wind storms, particularly the need for improvement in decision making in building construction, development of design and construction criteria for low-income housing. Other papers describe snow-management and microzonation studies to quantify, with better precision, the probabilities used in decision models. Some papers describe localized wind environments and wind loading (fluctuating internal, fluctuating external). Other papers analyze the dynamic response of tall buildings and towers, such as in crosswinds, wind direction, alongwind, and wind action with interference effects from similar surrounding buildings. Experiments show that by properly modeling a structure in a boundary layer wind tunnel, the investigator can obtain results which are dynamically fully comparable to a full scale situation. Another paper discusses the recommendations of the European Convention for Constructional Steelwork in calculating the wind effects on buildings and structures. The compendium can be appreciated by environmentalist, civil engineers, structural engineers, architects, physicists, students and professors of meteorology.

    • English
    Heating in Toroidal Plasmas 1978, Volume 1 contains the proceedings of the 2nd Joint Grenoble-Varenna International Symposium held in Grenoble, France, on July 3-7, 1978. The symposium provided a forum for reviewing the status of heating of toroidal plasmas as a means of creating a practically inexhaustible source of energy with maximum safety and economy. Topics covered range from nuclear beam injection to heating at ion cyclotron- and lower frequencies, as well as lower hybrid resonance heating and electron cyclotron heating. Comprised of 52 chapters, this volume first looks at the implications of Theoretical scaling laws, followed by a detailed account on the use of duality and complex vectorial space for the orthonormal decomposition of the electromagnetic field in anisotropic media. The reader is then introduced to the topology of Tokamak orbits; behavior of fast ions in a large Tokamak plasma during nuclear beam injection heating; and heating of a toroidal plasma by skin current. Subsequent chapters focus on parametric instabilities in weakly-inhomogeneous hot plasmas; wave trajectory and electron cyclotron heating in toroidal plasmas; considerations on the design of a 50-GHz gyrotron; and nonlinear dissipation of a finite bandwidth radiation in a plasma near electron cyclotron harmonic resonances. This monograph will be of interest to practitioners and research workers engaged in plasma physics.

The book focuses on the potential of solar energy as an alternative energy source. The selection first elaborates on plane incident solar radiation, relationship between global and net radiation, atmospheric pollution and solar radiation, and solar energy at ground surface. The manuscript then ponders on contribution to the study of nocturnal radiation very near the ground, computation of the diffuse solar radiation for Egypt, solar data application to Egypt, global radiation in Italy, and the distribution of solar energy in Greece. The text explores a simulated comparison of the useful energy gain in a fixed and a fully tracking flat plate collector; flat plate boosters for elevating temperatures; passive solar wall collectors; and a two-dimensional finite-difference solution for the transient thermal behavior of a tubular solar collector. The book then explores the optical and thermal performances of a half-circular, cylindrical concentrator; high-efficiency solar concentrator; scheme of automatic adjustment of accuracy of the inflatable solar collector; and solar battery system and its use for irrigation in Egypt. The selection is a valuable source of data for researchers interested in solar energy.

  • Oceanography and Surface Layer Meteorology in the B/C Scale

    Global Atmospheric Research Program Atlantic Tropical Experiment (Gate)
    • 1st Edition
    • Gerold Siedler
    • English
    Oceanography and Surface Layer in Meteorology in the B/C Scale is a collection of papers that deals with the oceanic and atmospheric boundary layers in the region in or close to the Intertropical Convergence Zone (ITCZ) in the Eastern Atlantic. Papers discuss global atmospheric circulation to improve weather prediction and climate modeling in line with the objectives of the Global Atmospheric Research Programme (GARP). In particular, the GARP Atlantic Tropical Experiment (GATE) addresses the means of estimating the effects of smaller tropical weather systems on synoptic scale circulations. GATE also facilitates the development of numerical modeling and prediction methods. One paper compares a mathematical representation of the transport of energy by convective clouds and the cloud free environment with a relationship based on the physical structure of the cloud and environment. Another paper analyzes model simulations made for various upwelling velocities, rainfall events, wind stress events, diurnal heating cycles, and internal tidal forcing using the GATE dominant scales of tropical weather systems. The model simulations show that in the GATE C-Scale demarcation area, no single process dominates. The collection will be appreciated by meteorologists, environmentalists, merchant marines, students studying hydrology, and by people working in the general earth sciences.

    Energy Resources and Conservation Related to Built Environment is a collection of papers that discusses energy resources, energy conservation schemes, better structure design or construction, and alternative energy resources. Some papers discuss energy conscious design methodologies for townhouses, use of composite components in structural framing, and also energy and physical planning of houses. One paper explains the process and techniques of the water/energy manual developed as part of the Water/Energy Conservation Project sponsored by the U.S. Department of Energy. Building site selection, window design, energy auditing, boiler efficiency, and power factor correcting capacitors help in preserving energy; at the same time, these also provide thermal comfort. Alternative energy sources include small scale tidal energy generation, airtight woodstoves, wind energy, methane recovery, and hybrid energy systems. Other papers discuss case studies in energy and design, such as the utilization of the Hittman methodology in Boulder, Colorado; the student-performed energy audits done in Minneapolis and Minnesota; and the energy performance of New Zealand's built environment. The collection is beneficial to environmentalists, civil or structural engineers, architects as well as researchers whose works are related with energy conservation and production.

    Advances in Composite Materials is a collection of papers that discusses fiber reinforced composite materials pertaining to their mechanical and failure properties. One paper explains the design and fabrication of a GrFRP concept car by the Ford Motor Company which uses as much as possible graphite fiber in the body, chassis, and powertrain. Another paper discusses the sorption behavior of glass-fiber reinforced composites, as well as the influence of diffusing media on the deformation and failure behaviors. One paper examines the physical, elastic, viscoelastic, and inelastic properties of multiphase short fiber composite materials using the fiber aspect ratio, fiber volume fraction, and properties of the constituent phases as several variables. Another paper describes a procedure to measure the changes in stiffness properties of a unidirectional fibrous composite (such as glass fiber reinforced polyester) caused by fatigue damage. One application of carbon fiber reinforced thermoplastics is in a sleeve bush molded from nylon 66 containing 30 percent fiber reinforcement with PTFE and silicone oil. The material has low frictional, high wear performance characteristics. The Penny and Giles Potentiometers Ltd. use this component on a joystick for gun directional control. The collection can prove useful for design engineers, materials engineers, scientists involved with composite materials, and industrial researchers in the fields of materials science.

  • Global Review of Human Settlements

    A Support Paper for Habitat: United Nations Conference on Human Settlements

    Global Review of Human Settlements: A Support Paper for Habitat: United Nations Conference on Human Settlement reviews global human settlement conditions and the factors affecting their present and future developments. The report presents information, analyses, and conclusions. It analyzes the causes and effects of the urbanization process; describes the quality of life in human settlements; and presents relevant definitions, list of tables, and country composition by regions. The urbanization process pertains to demographical and economical aspects. Demographical aspects include city size, city growth, migration, and natural increase. Natural population increase accounts for about one-half of urban population while migration from rural to urban places account for the other half. One aspect of the quality of life in human settlements is the prevailing housing conditions. According to the report, housing conditions in most developing countries have become worse in the past ten years due to rapid population growth, to rates of migration from rural to urban places, and to the decline of the rate of increase in national output. The report also contains a list of criteria used nationally to distinguish urban areas from rural areas. For example, South Korea defines urban areas as Seoul or municipalities with 5,000 or more inhabitants. The report is suitable for demographers, economists, environmentalists, ecologists, and policy makers involved in rural development and social services.
