Surveys release

Probably the most complete study of river water quality w as completed by the U.S. Geological Survey, released in early 1987 and periodically updated. The initial survey was coordinated by Smith and Alexander (USGS) and Wolman (The Johns Hopkins University), including water quality records from two nationwide sampling networks. The network included over 300 locations on the major nvers of the United States. Twenty-four water quality parameters are measured. Originally, the two networks were comprised of (1) the National Stream Quality Accounting Network (NaSQUaN) and (2) the National Water Quality Surveillance System (NWQSS). Locations of stations are shown on the map in Fig. 1. The measured water-quality indicators include ... 

The prevalence of alternative medicine use in the United States is steadily increasing. One may even describe the phenomenon as an explosion. A landmark survey published in 1993 estimated that 33.8% of Americans used one type of alternative therapy. " A follow-up survey released in 1997 reported that...

Ten years ago I worked as a consultant to a dozen medical practitioners. Now, I regularly consult with more than 120 physicians. Why In part, it is because I am better known The more important reason is that most physicians know very little about herbal medicine, and their patients, in large numbers, are now taking herbal products. In fact, a recent consumer research survey released in 1998 reported that 42 percent of the people polled used some form of alternative medicine. The survey also noted that 75 percent of the people said they would be likely to use herbal medicine, and 74 percent of those reporting the use of alternative medical said they used it along with conventional health care. Of those people, 61 percent reported that their physicians were aware of these complementary treatments. 

The use of semi-synthetic derivatives as drugs developed from plant natural product lead compoimds began at the end of the nineteenth century and may be exemplified by drugs like aspirin (acetyl salicylic acid). From then on, the potential of plant-derived compounds as leads in drug discovery has been realized on numerous occasions [8], A survey released recently revealed that over 40% of the new small-molecular single chemical entity drugs introduced to the market from 1981 to 2006 are natural product derivatives, with 28% of them being chemical semi-synthetic modifications...

Conventional TNT-equivalency methods state a proportional relationship between the total quantity of flammable material released or present in the cloud (whether or not mixed within flammability limits) and an equivalent weight of TNT expressing the cloud s explosive power. The value of the proportionality factor—called TNT equivalency, yield factor, or efficiency factor—is directly deduced from damage patterns observed in a large number of major vapor cloud explosion incidents. Over the years, many authorities and companies have developed their own practices for estimating the quantity of flammable material in a cloud, as well as for prescribing values for equivalency, or yield factor. Hence, a survey of the literature reveals a variety of methods. 

A. B. Sheremetev and N. N. Makhova (N. D. Zelinsky Institute of Organic Chemistry, Moscow, Russia) and W. Friedrichsen (University of Kiel, Germany) have reviewed the monocyclic furazans and furoxans. While much of the early work in this area was published in the German and Italian literature, more recently, a large amount has appeared in Russian journals, much of it being released for publication only during the last ten years. This survey should be of great utility to Western readers. 

Opioids. Reactions to morphine, codeine phosphate, meperidine, fentanyl and its derivatives are uncommon. Because of their direct histamine-releasing properties, especially regarding morphine and codeine, distinction between anaphylaxis and non-immune-mediated histamine release is not always easy. Only 12 cases were recorded in the last 2 years epidemiologic survey in France, 9 of them being related to morphine administration [9]. 

Surveys of degree of use to combine with measured releases in such uses are also needed. 

The mounted samples were placed in the XPS vacuum chamber, and the chamber was evacuated prior to testing. The samples were exposed to the X-rays at 14.0 kV and 300 W. The approximate sampling area for the XPS is 1.0mmx3.5mm with a sampling depth of approximately 35.0 A at a 45° exit angle. Figures 16 and 17 show the survey scans from the epoxy and composite sample, respectively. Both show the presence of fluorine, which indicates the probable presence of a mold-release agent. 

A survey of the ability of various marine invertebrates and their isolated tissues to accumulate prostaglandins from surrounding fluids has led to the speculation that some marine invertebrates may rely on this mechanism to obtain their physiological requirement of prostaglandins [107], It is further speculated that P. homomalla, with its wealth of prostaglandins, may be the ultimate provider of these substances in the Caribbean through release and subsequent uptake by dependent species. 

The total and individual flavonoid contents in commonly consumed fruits and vegetables can be found in several recent surveys of the literature (Arabbi and others 2004 Franke and others 2004 Chun and others 2005 Harnly and others 2006 Sun and Powers 2007). They have been collected and compiled into a database (USDA Flavonoids Database Release 2.1, 2007). Table 5.1 enlists some of the most typical flavonoids, found in the major subgroups just discussed, for selected popular fruits and vegetables based on this database and current literature.
