Quick scan

A quick scan of the collection of structures in Part Three will confirm the high level of activity and accomplishment which has been associated with the field of chemical synthesis over the past three decades. Upon closer inspection, it becomes apparent that the rate of achievement of successful syntheses has been increasing steadily with time. As of this writing (1988) there are many laboratories in which outstanding work on multistep synthesis of complex molecules is being carried out. One consequence of this intense effort is that the problem of keeping track of the literature of synthesis has become a difficult one for investigators and students. The... [Pg.359]

A slightly more subtle heuristic lies behind the conditions "y + Y2 = 1 + MinCx x-j )" and "y + y3 = xq + in A. A quick scan of verification conditions (5) and (6) shows that within the main loop whenever is decreased by 1 (and we lave already agreed that at g, > 1 and so... [Pg.171]

Recently, we described the application of a silicon microfluidic reactor to the assembly of oligo-0-peptides (Llogel et al. 2006). The microreactor not only allowed for quick scanning of reaction conditions, but also the procurement of synthetically useful amounts of peptides (Curran 2001 Curran and Luo 1999 Zhang 2004). [Pg.13]

Are the results applicable to my patient Is my patient represented Were the clinically important outcomes considered How long did the treatment last Are the treatments worth the potential benefits, harms, and costs Can we provide the treatment In the Methods section, quickly scan the inclusion and exclusion ctitetia to see if yout patient falls within the type of patient enteted into the study. If necessary, adjust the NNT so that the expectations for benefit match the divergence of your patient from the average patient in the study population. Factor in your preferences and expectations and preferences of your patient and family. [Pg.430]

Stoddard solvent, etc. Other organic compounds containing C-H bonds will introduce positive interferences in the IR method however, the NIOSH GC methods are also very susceptible to extraneous compounds. With less sophisticated infrared spectrometers, the analysts will have to manually measure the peak intensities. However, since a majority of samples are usually negative, a quick scan can eliminate these without any measurement. The working range is somewhat small, up to approximately 2 mg hydrocarbons per tube being on chart. For off-chart samples, dilutions can be made quickly and simply. [Pg.48]

Quick scan survey of the industrial processes at plant level to get an initial overview of the processes and technologies used as well as a collection of basic data, e.g. amount of chemicals used, cost of chemicals purchased, number of pieces or other indications that might be used as unit of payment2 in the Chemical Leasing contract. [Pg.135]

As discussed in Chapter 20 by Apte and Ugwu, the future for new, unusual excipients that have exotic properties is hot and sunny. A quick scan of pharmaceutical science and pharmacology journals demonstrates very active research that could bear fruit unimaginable at this time. [Pg.13]

Despite increasing acceptance by scientists, some people viewed the synthesis of natural compounds as unnatural. Indeed proponents of the vital force theory can still be found on a quick scan of the Internet more than 100 years after it was discredited as a scientific theory. For example, vestiges of the vital force theory linger in the belief that vitamins from natural sources are somehow healthier than vitamins that are synthesized. [Pg.56]

A quick scan of newspapers, television, science magazines, or the internet on any given day has a fairly high likelihood of encountering a story (usually accompanied by a creative headline such as those above) regarding human health concerns linked to dusts, soils, or other earth materials. Many such concerns have been recognized and studied for decades, but new concerns arise regularly. [Pg.4805]

No powder diffraction experiment should be started at 20s = 0°, since the extremely high intensity of the incident beam at full tube power may damage the detector even when the narrowest slits have been used. The most dependable way to determine 20s for an overnight or a weekend experiment is to perform a quick scan at 5 to 10 deg/min beginning at the minimum allowable Bragg angle and ending at 20e = 30 to 40°. Based on this result, the correct 20s may be properly selected. ... [Pg.324]

The end angle should be selected as high as possible when experimental data will be used for precise unit cell or crystal structure refinement. This usually can be established by a quick scan (5 to 10 deg/min) with 20s ... [Pg.325]

You are using Fe Ka radiation to collect powder diffraction data employing powder diffractometer C (see problem 4). After several quick scans, you established that the receiving slit with the aperture of 0.03° results in both acceptable resolution and intensity. Bragg peaks appear to have a full width at half maximum between 0.4 and 0.5° 20. What is the largest allowable step during data collection and why ... [Pg.337]

You are about to perform a quick scan from 5 to 70° 20 to verify the crystallinity of your material and to check whether or not the receiving slit is of adequate width. You are planning for the experiment which will take 10 to 15 min overall. Which scanning mode (step scan or continuous scan) is the best to accomplish the task and why ... [Pg.337]
