SUBJECTS kilogram

More and more authors use Eq. (8) which gives AH and AS a more theoretical base than Eq. (7). However, it must be remembered that relation (8) has been established for reactions in the gaseous phase or at the best in highly diluted phase. This is not the case with many of the polyesterification systems studied where concentrations are high and expressed in term of mole per kilogram and not, as normally, in mole per liter. The consequences of these approximations are not clear and it is obvious that a considerable amount of additional work must be carried out on this subject. 

The volume of distribution is expressed as a fraction of the body weight, and the spreadsheet calculates Vd in liters using the subject weight in kilograms. 

The entire determination, from gas shutoff to printout from the computer, rarely exceeds 3 to 4 minutes for normal solids. And since all measurements are taken by the instrument, they are not subject to personal error of observation. The size of solids test sample is of the order of a kilogram or less. 

The radiofrequency pulses involved in MRI cause thermal heating of the tissues, and are thus subject to FDA limits on the amount of RF power that is transmitted to a subject during a medical scan. The RF power unit is specified as the specific absorption rate (SAR) and is measured in watts per kilogram of body tissue (W/kg tissue). Powers that exceed this level put the subject at risk of tissue damage incurred as a result of the tissue s inability to remove the heat through blood flow. 

Gauthier et al. <2005JOC5938> elaborated a synthetic route to 148, which is an important biologically active compound. These authors found that 147 can be subjected directly to cross-coupling process with the appropriate boronic acid, and there is no need for the halogenation of 147 to an intermediate for this cross-coupling. The product 148 was obtained in kilogram quantities in almost quantitative yield. 

Litre—is defined as the volume occupied hy one kilogram of water at its temperature of maximum density (4°C) and subjected to normal atmospheric pressure . The litre is considered as the standard unit of volume for all volumetric measurements. 

The Allende, Murchison, Murray and Orgueil meteorites are particularly highly prized for research into stellar grains, since several kilograms of this material have been identified in each of them. This is sufficient to be able to take samples of the order of 1 g without damaging the source. Such samples can then be subjected to compositional analysis. But how can we extract these stellar jewels, measuring at most 1 /rm in diameter, from the matrix in which they are embedded The best way of finding a needle in a haystack is to bum the hay. Cosmochemists employ basically the same method when they use chemical processes to isolate star dust trapped in meteoritic stone. They may then analyse... 

Health experts advise that moderated amounts of caffeine from 100 to 300 mg per day are acceptable. Adult Americans consume approximately 250 mg of caffeine per day. The LDJ0 (the lethal dose that kills 50% of a test population of individuals subjected to a substance) of caffeine for humans is estimated between 150 and 200 mg per kilogram of body weight. The amount of caffeine in some popular food items is given in Table 18.1. 

The subject has been discussed by G. W. Stose, C. Herrmann, J. C. Chorley, etc. According to J. W. Richards, the furnaces at Niagara consume 11-6 kilowatts per hour per kilogram of phosphorus. 

Meanwhile, we should avoid terms like "the LSD state." we should not believe that the statement, "x took LSD" (or any powerful psychedelic drug), tells us much about what happened to x s consciousness, indeed, a statement like "subjects were administered 1.25 micrograms of LSD per kilogram of body weight," commonly found in the experimental literature, is especially misleading because it seems so precise. It must be replaced by statements like "subject number 2 was administered such and such as dose of LSD, which then produced a d-ASC of type X, while subject number 3 did not enter a d-ASC with the same dose of LSD."... 

The Sepracor group demonstrated that (l/ ,2S)-indene oxide 26 could be prepared from readily available indene 25 in the presence of 1.5 mol% of (R,R)-MnLCl and 13% NaOCl in dichlo-romethane in 83% yield and 84% ee (Scheme 24.2). Chiral indene oxide 26 was then subjected to nucleophilic opening with ammonia to provide /ram-aminoindanol, which was transformed without isolation to its benzamide under the Schotten-Baumann condition (83% ee, >99.5% ee after recrystallization). The optically pure trans-benzamidoindane was then converted to the optically pure benzaoxazoline 27 by exposure to 80% H2S04, followed by addition of water to give cis-1-amino-2-indanol.53 54 The sequence was demonstrated on multi-kilogram scale to prepare optically pure (IR, 2.S )-1 in 40% yield from indene. 

Black phosphorus was discovered by Bridgman,8 who prepared it by subjecting white phosphorus at 200° C. to pressures of 12,000 to 13,000 kilograms per square centimetre. 

A raw water coutaiuiug 140 mg/L of dissolved solids is subjected to a coagnlatiou treatmeut usiug alum. If the optimum alum dose as determiued by ajar test is 44.86 mg/L, calculate the kilograms of calcium bicarbouate required.
