Impact high rate

MPI is especially valuable for elemental analyses with typical useful yield of 10 . Because SALI is laser-based, expected improvements over the next few years, in particular for vacuum-ultraviolet laser technology, should have a significant impact. High repetition rate Nd—YAG systems with sufficient pulse energy are already available to 50 Hz, and probably can be extended to a few hundred Hz. 

The suppliers of nylon 46 have laid particular emphasis on the fact that this polymer, with its highly symmetrical chain structure, leads to both a high level of crystallinity and a high rate of nucleation. In turn the high nucleation rate leads to a fine crystalline structure which in this case is claimed to lead to a higher impact strength (dry as moulded) than with nylons 6 and 66. 

If this is a correct analysis of it, then the chief problem with Brush s overall account—aside from any issue about the historical evidence in its favour—is that, by agreeing with Maher and Lipton that the novel predictions counted more while denying that they counted sufficiently more to outweigh the total effect of the accommodations, it ends up in no man s land. Brush may have an explanation for why special attention should have been paid to the predictive successes (they carried a lot of impact per unit , as it were) but this does not, despite his claims and despite, perhaps, first appearances, translate into an explanation for what he accepts is the historical fact that Mendeleev s periodic law attracted little attention before 1874—that is, before the initial success of the predictions. What his account would lead us to expect is, on the contrary, a high rate of credit for, and interest in, Mendeleev s scheme before 1874 and a somewhat higher rate afterwards. 

Campbell and coworkers269 also published a kinetics study of the reverse water-gas shift over Cu(110) in 1992, and the results were cast in terms of the redox mechanism (reverse of Scheme 60, left side). A hydrogen-induced surface phase transition was suggested to impact the rate at high H2/C02 ratios, as the rate was found to exhibit a saturation-like behavior with increasing P(H2) when 5 Torr of C02 was used, but continued on a log-linear trend when 150 Torr of C02 was... 

Gratton et. al. in [34] describes a least squares regression method to model heartbeat artifacts and to filter it out adaptively. Since the heartbeat rate is approximately 1 Hz, it is necessary that data is sampled at a sufficiently high rate (e.g. above the Nyquist rate) so as to represent and filter the artifacts out correctly and have minimal impact on the signal of interest itself [98]. 

The last include wet and dry deposition of particles and solutes and gas exchange across the air-sea interface. Because of proximity to source, coastal waters tend to be more polluted than the open ocean. A notable exception is the worldwide acidification of surface waters caused by CO2 emissions. Of all the coastal waters, estuaries tend to be the most impacted. This is due to high rates of pollutant loading and to natural processes that act to concentrate these pollutants in the local sediments and biota. This is most unfortunate as estuarine waters support the world s largest fisheries and are where recreation is concentrated. 

The disruption and fragmentation of the reactor core as a result of the excursion hurled all the capsules from both locations at least 500 feet away. The Pb styphnate sample which had been mounted on the pressure vessel showed evidenoe of a high-order detonation, which was assumed to be the result of the high rate of energy input from the KIWI—TNT test. This assumption was based upon several premises. Primarily, the possibility of the material detonating as a result of impact rather than by radiation did not seem reasonable, since the other sample... 

If, on the other hand, the excitation energy of the metastable is lower than the dissociation energy of the species AB, the latter can only be decomposed either by dissociative de-excitation of short-lived electronically excited states, or by ion-molecule reactions, or by electron impact. Much higher plasma energy values are necessary to produce a high rate of decomposition of the species AB in such systems28,44 (e.g. C/02,TiN/Cl2). 

Inhalant abuse is found in both urban and mral areas of the United States and Canada. Research indicates social and economic rather than racial and cultural factors in general impact the rate of inhalant abuse. Poverty, physical or mental abuse as a child, poor grades in school, and dropping out of school are all associated with increased inhalant abuse. At particularly high risk are Native American youths who live on reservations where poverty and school dropout rates are high. 

Interactive consideration of the dynamics of the biosphere as a climatic system component is particularly interesting. The importance of this problem can be exemplified by estimates of the climatic impact of the clearing of tropical forests in the Amazon basin obtained by Bunyard (1999). The Amazon River basin, consisting mainly of wet tropical forest (WTF), performs several important and still inadequately considered functions, including the input of energy from tropical to higher latitudes, which is under threat in view of the high rate of WTF destruction. 

Obviously, results vary a great deal between countries and the aggregate results underplay the regional dimension within Europe. In the countries with high rates of import from non-EU countries before the implementation of a climate policy, imports have already deeply penetrated their territory. Therefore, they are less protected by transportation costs and are more sensitive than countries with low rates of non-EU imports. The trade impact also depends on the size and location of the country, and the location of its population (due to transport costs, inland countries or large countries with population living mostly inland are proportionally less impacted than small countries near the coast) and on its extended cost increase. 

For many applications the resistance of the material to shock loading is an important property. Here we find ourselves, contrary to the previous section, on the very short side of the time scale. For the impact strength the short-term tensile strength as well as the ultimate strain play a role the impact strength is, in fact, the energy needed for rupture at a high rate of deformation, J impact strength accurately and uniquely. 

Another problem is the impact of "mild" mutations— those which produce only small effects, which arise at relatively high rates, and which are inefficiently selected out of populations. Although it is currently virtually impossible to detect such effects clinically in humans, it is clear that they contribute markedly to the total mutational load in Drosophila, where they outnumber "severe" (recessive lethal and semilethal) mutations by a factor of at least 10 and significantly reduce the health of the typical wild fly. The same is true for mutations induced by ethyl methanesulfonate, but other chemicals have not been tested.
