  • Continuing and updating the Encyclopedia of Water Science over the past four years has been an exciting but daunting task. It has been exciting because the subject is so critical to life and living, and daunting because the original editors set such a high standard. As ever, water is the central focus in environmental science. In addition to all the critical factors cited in the Preface to the first edition, global warming has now become more certain so that water issues will become even more important....

  • As a major rice exporter worldwide, the quality of rice has become a central issue for farmers in Vietnam, especially in the rainy harvest season. Therefore, it is important to dry the rice as quickly as possible to prevent damage but maintain quality. Conventional drying techniques such as flat bed dryers can take up to 8 hours (or more) to dry the moisture rice to safety. High-temperature drying can allow the rice to dry more quickly, so space and time taken to dry the rice can be shorter nhieu.Nghien agricultural science...

  • My wife Judy, my children, and my friends urged me for some time to write about my life and the fascinating period of science I was lucky to be part of. For years I resisted, mainly because I was still fully occupied with research, teaching, and various other commitments. I also felt it was not yet time to look back instead of ahead. However, I slowly began to realize that, because none of us knows how much time is still left, it might be ill advised to say ‘‘it is not yet the right time.’’ I therefore started to collect material and to organize my thoughts for...

  • Today, through television, most Americans have been exposed to the application of forensic science to the justice system. Programs such as Law and Order, CSI, Crossing Jordan, Cold Case Files, Forensic Files, and American Justice feature police activities, forensic laboratory technology, and courtroom procedures. These programs have made the public aware of the important role that forensic science plays in the criminal justice system, and enrollment in criminal justice and forensic science courses in college and high school has increased markedly within the last 10 years....

Seilacher, Tübingen and YaleIn various periods throughout the younger earth history comparable changes in climate occurred globally and simultaneously. Such global events can be recon- structed with the help of reliefs, sediments and palaeosoils and their specific mor- phological, chemical and mineralogical properties. Desert margins represent inter- sections between arid and humid ecosystems.

  • Science is a way of making and using observations. The ap- plications of science have played a central role in the ad- vancement of civilization.The Latin origin of the word science (scire) can be translated as “to know.” While some people might think of scientific conclusions as unchanging facts, our understanding is never complete. As the understanding of nature grows, old ideas that no longer seem to fit our obser- vations are discarded. The so-called facts of science are often temporary while the methods of science (observation and analysis) are permanent....

  • Monthly rainfall data given by surface meteorological observations during the period 1961-2007 in Central Vietnam is used to calculate drought indices. Results show that drought conditions slightly increase in North Central Vietnam but decrease in South Central and Highland Central Vietnam. Significant drought periods often occur from January to March. The percentage of dry years during the period 1961-2007 is larger than that in the reference period of 1961-1990 in North Central while smaller in South Central and almost similar to that in Highland Central Vietnam.

  • (BQ) Ebook Earth science: Drought helps you know How can a region’s climate make it more likely to suffer from droughts? If seasonal rains are important for crops to grow in a certain country and those rains don’t happen for two years in a row, what may happen to the people of that country? Why do some scientists think that droughts will happen more often in the future?.

  • Changes in the use of land reflect a variety of environmental and social factors, necessitating an equally varied suite of data to be used for effective analysis. While remote sensing, both from satellites and air photos, provides a central resource for study, socio-economic surveys, censuses, and map sources also supply a wealth of valid information. Land Use Change: Science, Policy and Management presents spacial theories and methodologies that support an integrated approach to the analysis of land use change.

  • A: Basically, statistics is the “science of data.” There are three main tasks in statistics: (A) collection and organization, (B) analysis, and (C) interpretation of data. (A) Collection and organization of data: We will see several methods of organizing data: graphically (through the use of charts and graphs) and numerically (through the use of tables of data). The type of organization we do depends on the type of analysis we wish to perform.

  • It is a common practice in computer science for the words “computer” and “processor” to be used interchangeably. More precisely, “computer” refers to the central processing unit (CPU) together with an internal memory. The internal memory or main storage, control and processing components make up the heart of the computer system. Manufacturers design the CPU to control and carry out basic instructions for their particular computer.
