MEDLINE. Washington, DC National Library of Medicine. MEDLINE is a premier clinical literature database, providing abstracted information from over 4800 journals. MEDLINE covers the preclinical sciences, biomedicine, nursing, dentistry, veterinary medicine, and the healthcare system. The most effective way to find device information is to use appropriate Medical Subject Headings (MeSH) and subheadings. The relevant instrument-related MeSH terms are Surgical Equipment, with the narrower term Surgical Instruments. 

Drug delivery is covered more adequately, with a variety of MeSH terms including drug delivery systems, drug carriers, and infusion pumps, which has narrower terms such as infusion pumps, implantable, and insulin infusion systems. 

MEDLINE and PubMed, both produced by the National Library of Medicine (NLM), are the largest and best known bibliographic databases of biomedical journal literature. PubMed s iu-process records provide basic citation information and abstracts before the citations are indexed with NLM s Medical Subject Headings (MeSH) Terms and added to MEDLINE. To optimize the efficiency of a clinical search, PubMed offers specialized searches usiug method-ologic filters. These filters, based on work by Haynes and colleagues, are validated search strategies to identify clinically relevant studies...

In other searches, using only one of the four MeSH terms (isofluorate, DFP, diisopropylphosphofluoridate, or diisopropylphosphoro-fluoridate), 3,085 results were found for those terms. Therefore, the PubMed database uses these four terms as synon3uns and the same references are foimd in any cases. They represent most, but not all, tire publications involving DFP. It should be noted that with the abbreviation of "DFP" some nonrelated publications are referred to (i.e., "bacterial DFP-flavoproteins"). Unfortunately, there is not an established tradition of indicating the CAS number for a unique reference of the chemicals in scientific publications, and standard chemical nomenclature is not always used. The statistics of the distribution of publications over time is shown in Figure 57.1. 

As the number of elements in the mesh increases the sparse banded nature of the global set of equations becomes increasingly more apparent. However, as Equation (6,4) shows, unlike the one-dimensional examples given in Chapter 2, the bandwidth in the coefficient matrix in multi-dimensional problems is not constant and the main band may include zeros in its interior terms. It is of course desirable to minimize the bandwidth and, as far as possible, prevent the appearance of zeros inside the band. The order of node numbering during... 

Motor-driven, multistage reciprocating compressors have reportedly been the most popular choice for aeroderivatives. Motor-driven, oil-fiooded screw compressors are also used in some cases. High horsepower, multistage centrifugal compressors, similar to those used at many pipeline compressor stations, may be required for the newer heavy-duty units if the distribution pipeline pressure is insufficient (see Pipelines). Gas turbines have more stringent fuel-gas specifications in terms of cleanliness than do gas-fired boilers. Thus oil- and water-knockout systems, coalescing filters, and fine-mesh filters are used. 

Fermentation. The term fermentation arose from the misconception that black tea production is a microbial process (73). The conversion of green leaf to black tea was recognized as an oxidative process initiated by tea—enzyme catalysis circa 1901 (74). The process, which starts at the onset of maceration, is allowed to continue under ambient conditions. Leaf temperature is maintained at less than 25—30°C as lower (15—25°C) temperatures improve flavor (75). Temperature control and air diffusion are faciUtated by distributing macerated leaf in layers 5—8 cm deep on the factory floor, but more often on racked trays in a fermentation room maintained at a high rh and at the lowest feasible temperature. Depending on the nature of the leaf, the maceration techniques, the ambient temperature, and the style of tea desired, the fermentation time can vary from 45 min to 3 h. More highly controlled systems depend on the timed conveyance of macerated leaf on mesh belts for forced-air circulation. If the system is enclosed, humidity and temperature control are improved (76). 

Packed-Bed Fixed-Film Systems These systems were originaUy termed anaerobic trickhng filters because the first systems were submerged columns filled with stones run under anaerobic conditions (Fig. 25-57). A wide variety of packed media is now used ranging in size from graniiles 40 mesh to 7.5-cm (3—in) stones. Many systems use open structure plastic packing similar to that used in aerobic trickhng filters.
