  • Satellite altimetry was developed in the 1960s soon after the flight of artificial satellites became a reality. From the vantage point in space, a radar altimeter is able to measure the shape of the sea surface globally and frequently. Such measurements have a wide range of applications to oceanography, geodesy, and geophysics. The results are often revolutionary. For example, in oceanography; it takes a ship weeks or months to cross the ocean making measurements while the ocean is constantly changing its circulation, temperature, and salinity.

  • The first half of the 20th century saw a trend to increasing engine power, particularly in the American models. Design changes incorporated all known methods of raising engine capacity, including increasing the pressure in the cylinders to improve efficiency, increasing the size of the engine, and increasing the speed at which power is generated. The higher forces and pressures created by these changes created engine vibration and size problems that led to stiffer, more compact engines with V and opposed cylinder layouts replacing longer straight-line arrangements....

  • A mathemalical model is presented that describes heat and moisture transfer during the holpressing of MDF. The model includes conduction of heat between the press platens and the central layer of the mattress, phase change of water from the adsorbed to the vapor state and the convective heat and mass transfer through the edges of the mattress. This approach results in a three-dimensional unsleady-state problem in which the properties of the wood fibers, water and the wood-water system are dependent on temperature, mattress moisture content and steam pressure.

  • The mass media proclaimed the above as the new millennium began. Acad- emics and professionals have been holding conferences about it for a while now. Designers themselves have insisted on it all along. But what, exactly, does that statement mean? A proliferation of hip hotels and award-winning potato peelers do not an era make.

  • Perhaps nothing is so ingrained in our senses as the perpetual pulling of the earth on our surroundings. It’s always there, never changing. It’s been hugging solids, liquids and gases to the earth’s surface for over 4 billion years. Earth’s gravity is built into our descriptions of our world with words like up, down, and weight. Exactly what is weight? A weight is a force, nothing more. Your weight is the pull of earth’s gravity on your body. Likewise, the weight of your car is the force of the earth’s attraction for it. The greater the mass is, the...

  • Population Screening Mass genetic screening programs require tests of high enough sensitivity and specificity to be cost-effective. An effective screening program should fulfill the following criteria: that the tested disorder is prevalent and serious; that it can be influenced presymptomatically through lifestyle changes, screening, or medications; and that identification of risk does not result in undue discrimination or harm.

  • Introduction into CNC Technology In CNC milling the main function of the work part clamping devices is the correct positioning of the work parts. The work part clamping should allow a work part change which is as quick, easy to approach, correctly and exactly positioned, reproducible as possible. For simple machining controllable, hydraulic chuck jaws are sufficient. For milling on all sides the complete machining should be possible with as few re-clamping as possible.

  • Combustion involves change in the chemical state of a substance from a fuel state to a product state via a chemical reaction accompanied by release of heat energy. Design or performance evaluation of equipment also requires knowledge of the rate of change of state. This rate is governed by the laws of thermodynamics and by the empirical sciences of heat and mass transfer, chemical kinetics and fluid dynamics. Theoretical treatment of combustion requires integrated knowledge of these subjects and strong mathematical and numerical skills.

  • In the light of changes to health and safety law, and the continuing development of best practice by the event industry, the guide has been reviewed and revised. The advice in this publication has been tried and tested and lays down a firm foundation on which to organise health and safety at music events. Many of the chapters can be applied to other types of event which, although not necessarily having a musical theme, share some of the common characteristics of music events. This publication will enable event organisers, local authorities, the emergency services...

  • Substantial changes from the first English edition of this book (1993, Plenum Press, New York) have been introduced in this second edition. The content was rearranged such that all basic knowledge is contained in the first part of the book. This part was rewritten and to some extent simplified and can be used as a textbook for undergraduate students in electrochemistry and related branches. More advanced topics that will be of interest for people at a postgraduate level can be found in the subsequent parts....

  • Owners of high cash businesses used multiple cash equivalents from different banks and money services businesses to pay into policies and annuities. In one case, an insurer reported the owner of a landscaping business who paid the premiums on a universal life insurance policy with multiple money orders of no more than $1,000 each, some purchased on the same day at different post offices, or on separate visits to the same post office, creating the appearance of structuring.

  • In a certain sense, the field of drug metabolism (DM) is standing still. More specifically, the basic experiment of drug metabolism (i.e., administering a new drug to an animal or human and determining the structures, amounts, and disposition of the metabolites) has changed very little over a period of decades. Remarkably, the experimental design and resulting data set from a typical absorption, distribution, metabolism, and excretion (ADME) study conducted today would be instantly recognized and understood by DM scientists from 50 years ago.

  • The issues of media, identity and gender are being discussed all over today. They have become integral to the discipline of media studies. The reason is the popularity and diversity of media as a source of mass consumption and its influence on constructing ideas and generating debate. The media scene in India has expanded in the recent times as there is a plethora of media choices available to the audiences. Media structures and systems have also undergone a sea change with privatization and globalization. Huge corporations with their own profit motives own media houses.

  • In classification, we wish to construct a model from a set of historical data. The model should describe a predetermined set of data classes. For example, in traditional direct marketing there are usually two predetermined classes, namely the “responder” class and the “non-responder” class. An observation or sample is a record representing an entity, e.g. a customer. Each observation is associated with a certain number of characteristic attributes and belongs to exactly one of the predetermined classes.

  • Furthermore, much has changed in north India since Dyson and Moore’s account was written. In addition to the cumulative impact of family planning programmes (which have made contraception an issue that can be discussed publicly) and changes in consumption patterns (with the rise of mobile phones, and a great extension of mass media into rural and poor urban areas, for example) there have also been major attempts to raise school enrolment levels and to reduce gender disparities.

  • DNA testing is performed by mutational analysis or linkage studies in individuals at risk for a genetic disorder known to be present in a family. Mass screening programs require tests of high sensitivity and specificity to be costeffective. Prerequisites for the success of genetic screening programs include the following: that the disorder is potentially serious; that it can be influenced at a presymptomatic stage by changes in behavior, diet, and/or pharmaceutical manipulations; and that the screening does not result in any harm or discrimination.
