Wide tolerances

Look up a standard method of measurement (e.g., the determination of iron in an ore, found in most quantitative analysis textbooks). Are factor tolerances specified What might be the economic consequences of insufficiently controlling a factor that has narrow tolerances What might be the economic consequences of controlling too closely a factor that actually has wide tolerances ... 

Duplicator and Business Form Inks. Duplicator sheet-fed machines require very press-stable yet quicksetting inks. They must also possess good lithographic properties of wide tolerance for fountain solution and provide good printing properties on a wide variety of uncoated papers. 

A cheap and efficient enantioselective aza-Henry reaction of nitromethane with a variety of A-protected arylaldimines has been reported.73 Using zinc triflate and (-)-A-methylephedrine at -20 °C, yields and ees of up to 99% have been achieved with wide tolerance of aryl substituent in terms of both electronic nature and position. The auxiliary is also easily recycled. 

Determination of volatile matter content using a slower heating rate is applicable to a wider variety of coals. However, the values obtained are sometimes lower (1 to 3% absolute) than those obtained from the regular method. This illustrates the empirical nature of this test and the importance of strict adherence to detailed specifications. The complexity of the constituents of coal that undergo decomposition during this test makes it necessary to have wide tolerances for reproducibility and repeatability. 

Trematomus is an Antarctic species, Oncorhynchus has wide tolerance, and the other two species are warmwater fish. 

Most cell lines present a wide tolerance range to osmotic pressure. Given the osmolality of human plasma (290 mOsm/kg), it may be reasonable to assume that this is an optimal value for human cells cultivated in vitro, although it can be different for cells from other species. As a general rule, the optimal osmolality range for mammalian cells in culture is from 260 to 320 mOsm/kg, while for insect cells higher values are optimal, from 340 to 390 mOsm/kg. 

Although hot-pressing is usually regarded as an expensive process and only simple shapes with a wide tolerance on dimensions can be made, it provides the only route for several valuable materials. Continuous hot-pressing methods have been developed for some magnetic ferrites and piezoelectric niobates. They olfer higher production rates but tool wear is very severe. 

The reactions of different individuals to a given potential irritant can vary, as there is a wide tolerance range. The majority of essential oils in aromatherapy used in the correct dilutions are perfectly safe, but potential irritants are usually used at a strength of 1% or less. 

The combination of active drug, preservative, and vehicle usually results in a hypotonic formulation (< 290 mOsm). Simple or complex salts, buffering agents, or certain sugars are often added to adjust osmolarity of the solution to the desired value. An osmolarity of 290 mOsm is equivalent to 0.9% saline, and this is the value sought for most ophthalmic and intravenous medications.The ocular tear film has a wide tolerance for variation in osmotic pressure. However, increasing tonicity above that of the tears causes immediate dilution by osmotic water movement from the eyelids and eye. Hypotonic solutions are sometimes used to treat dry eye conditions and to reduce tear osmolarity from abnormally high values. 

In weaving the wire, there are wide tolerances, especially for the fine mesh. 

Set out balled-and-burlapped plants in early spring. Hornbeams are excellent urban trees and. while preferring full sun, will grow satisfactorily in partial shade. They are widely tolerant of sanous soil tvpes. 

The replacement of the N-acetyl group of the N-acetylglucosaniine unit is widely tolerated (Table 9). Especially striking is again the selective fucosylation of the glycuronamide derivatives (entries 11-15). Heterocyclic substituents on the acceptor apparently do not affect the enzyme either (entries 8-10). Nonnatural fucose donors are also recognized by FucT III and transferred in the expected way to form Lewis trisaccharides or sialyl-Lewis tetrasaccharides, respectively (see Fig. 14). 

The stability of the nonsupported catalyst under the reaction conditions is a prerequisite that must be firmly established both in the presence and in the absence of the intended support. Possible candidates to be supported should be catalysts of great versatility and of wide tolerance of structurally different substrates, possibly with a high catalytic efficiency and with a well-tested stability. The... 

It is appropriate mentioning here again the accuracy problem with respect to kinetic parameters and its relation with general modeling concepts. A distinct uncertainty in the selection of parameters and a wide tolerance box for their variation are among the main reasons for discrepancies between different models, which in turn stimulates the creation of new ones. This is the reason why the idea of using exclusively the kinetic parameters obtained by quantum chemical calculations instead of experimentally determined values seems attractive. Indeed, contemporary theoretical methods can give results, which in some... 

Typically sp or sp-hybridized stannanes with organohalides or triflates, but alkyl, allyl and benzylstannanes also been used Wide tolerance of functional groups. Major drawback use of potentially toxic tin reagents. 

While the survey data sources are limited, the results suggest that, nationwide, our standards have been eroded and that unethical behavior is widely tolerated. 

These data are subject to relative wide tolerance ranges therefore, individual testing of the penetration and the softening point R B is advisable if eventual correlation with other values is attempted,...
