  • Behavioral medicine has now matured as a field to the point where all recognize that different populations are presented with different issues. Psychological reactions and patterns affect the health and well-being of children, as well as adults, and numerous standardized instruments for the assessment of a variety of areas of children's functioning are currently available.

  • Introduction: Alcohol usually means ethanol/ethyl alcohol. It has a long history for the human being, and gives euphoric effects and sometimes improves the human relationship. In contrast, there are many cases of violence, injuries, homicides and traffic accidents with drinking; close relation can be observed between ethanol and crimes/accidents. When forensic autopsies are performed, ethanol concentrations in blood and urine are routinely measured. GC analysis of ethanol using the conventional packed columns is described in many of literature [1, 2].

  • Introduction: Oleander (Nerium oleander and Nerium indicum) is a relatively small evergreen tree of an Indian origin, and growing in Honshu, Shikoku, Kyushu and Okinawa islands in Japan. The plant contains cardiac glycosides in its leaves, stems and flowers and is known as one of poisonous plants; poisoning and fatal cases for domestic animals and humans due to ingestion of this plant were reported [1–6]. The main toxin of oleander is oleandrin. Oleandrin can be measured using cross-reaction of an immunoassay kit for digoxin [1], TLC [2], HPLC [7, 8] and LC/MS [3, 6].

  • The first edition of the Handbook of Micro/Nanotribology was published in the Spring of 1995. Soon after its publication, the first-of-a-kind monograph became a reference book for the novice, as well as experts, in the emerging field of micro/nanotribology. Since the field is evolving very rapidly, we felt that the monograph needed a second edition. The second edition is totally revised. The scope of the first edition has been expanded. In the first part, Basic Studies, two new chapters on AFM Instrumentation and Tips and Surface Forces and Adhesion have been added.

  • The purpose of this handbook is to provide in one location detailed, up-to-date information on various facets of mass measurement that will be useful to those involved in mass metrology at the highest level (at national standards laboratories, for example), in science and engineering, in industry and commerce, in legal metrology, and in more routine mass measurements or weighings. We have pursued clarity and hope that we have in some measure succeeded.

  • Quality control is a standard which certainly has become a style of living. With the improvement of technology every day, we meet new and complicated devices and methods in different fields. Quality control explains the directed use of testing to measure the achievement of a specific standard. It is the process, procedures and authority used to accept or reject all components, drug product containers, closures, in-process materials, packaging material, labeling and drug products, and the authority to review production records to assure that no errors have occurred....

  • Standard laboratory methods for measurement of soil nitrate (NO3–N) use various procedures and instruments to analyze soil samples taken from the field and transported to the laboratory. Concerns with these procedures range from delays in measurement time, the high cost of soil sampling and analysis, high labour requirements, and the need to aggregate samples. With recent advances in using the ion-selective electrode, as presented in this chapter, soil NO3–N can now be measured directly, rapidly, accurately, at low cost, at a fine scale, and in real-time right in the field....

  • Aquatic scientists have always been intrigued with concepts of scale. This interest perhaps stems from the nature of ßuid dynamics in oceans and lakes — energy cascades from spatial scales of kilometers down to viscous scales at centimeters or less. Turbulent processes affect not only an organism’s perception of, and response to, the physical environment, but also the interaction between species, both within and across trophic levels.

  • According to most social scientists, a generation is about 25 years in length. By that measure, this second edition of the Handbook of Adolescent Psychology represents a generational shift, for it was fully 25 years ago that the first edition of this volume was published. A cursory glance at this edition’s table of contents will show just how broadly the field has grown in that period of time, and a careful reading of the volume’s chapters will reveal that the generational shift has been as deep as it has been broad...

  • The photodiode device structure, which has developed almost simultaneously with Si based p-n junctions, has had a dramatic impact on everyday life, especially in the field of communication and sensing. The last few decades have seen optical techniques come to dominate long-haul communication and photodiode technologies, serving as an energy transducer in the receiver end, which can convert optical data into electrical signals for further processing.

  • The aim of this work is to provide an introduction into nanotechnology for the scientifically interested. However, such an enterprise requires a balance between comprehensibility and scientific accuracy. In case of doubt, preference is given to the latter. Much more than in microtechnology – whose fundamentals we assume to be known – a certain range of engineering and natural sciences are interwoven in nanotechnology.
