Cocktail source

Up to now, the precursor solutions for Ba, Sr, and Ti are usually contained in separate reservoirs to permit variation in the input ratio of the cationic elements. However, for mass-production it is much more desirable to use the cocktail source which contains all three precursors in one reservoir for more reproducible deposition. Use of the cocktail source is not proper for research because changing the cationic composition is not easy. Furthermore, the cationic composition of BST films is not only dependent on the input precursor ratio hut also on the deposition temperature, as discussed helow. Therefore, use of a cocktail source is possible only... 

In addition to protein impurities emanating directly from the source material, other proteins may be introduced during upstream or downstream processing. For example, animal cell culture media are typically supplemented with bovine serum/foetal calf serum (2-25 per cent), or with a defined cocktail of various regulatory proteins required to maintain and stimulate growth of these cells. Downstream processing of intracellular microbial proteins often requires the addition of... 

Nearly 40 million people are infected with the human immunodeficiency virus (HIV). Over half of those infected reside in sub-Saharan Africa. Worldwide during 2004, it is estimated that nearly 14,000 people a day were infected. Human immunodeficiency virus type 1 is the primary etiological source for the acquired immunodeficiency syndrome (AIDS). Fortunately, people infected with HIV are leading longer and more productive lives due to the availability of more effective therapies. Better medicines have evolved due to the efforts of scientists worldwide who find targets and compounds that inhibit the virus life-cycle. The current treatment for HIV infection is via a drug cocktail that usually includes a protease inhibitor (PI), a nucleoside reverse transcriptase inhibitor (NRTI), and a non-nucleoside reverse transcriptase inhibitor (NNRTI). 

The nature of study objectives in environmental research is often multivariate. Several pollutant patterns from different, sometimes unknown, sources may occur. The state of pollution of a sampling point, line, or area in any environmental compartment, whether atmosphere, water, soil, or biota, depends mostly on the nature of the different sources of pollution. Stack emissions are characterized by a multi-element pattern. Waste water effluents contain different contaminants, ranging from heavy metals to cocktails of organic compounds. 

As with any diet, it s best to avoid alcoholic beverages for two reasons. First, they obviously are a source of empty calories. Second, they relax inhibitions and might lead you to eat more than you really want to. That said, when my wife went on the diet to lose a few pounds before we headed off on holiday, she replaced one of the mini-meals with a glass of wine in the evening. A 5-ounce serving has about 100 calories. If you d prefer a cocktail in the evening, an ounce and a half shot of distilled spirits of your choice—gin, vodka, rum—has 90 calories. Mix it with diet soda or water. 

Usually removal of the cell wall is reaUzed by treatment of plant material (leaves, tissue cultures, suspended cells, etc.) with a designed cocktail of enzymes such as cellulases, pectinases and/or hemicellulases, in an incubation medium of the appropriate osmolality to avoid cell burst. In addition, the physiological status of the source plant material also influences the release of viable protoplasts, and several other factors affect protoplasts release, including the extent of cell wall thickening, temperature, duration of enzyme incubation, pH of the enzyme solution, gentle agitation, and nature of the osmoticum [40].
