Achieved significance

Whereas soHd wastes can achieve significant flame temperatures, they are substantially below those associated with fossil fuels. These differences are... 

The hterature notes many other polyamide hoUow fibers, none of which have achieved significant commercial success. Included in this category are such polymers (some of which are cross-linked) as piperazinamides, hydrazine, substituted acrylamide, and modified and grafted nylons. 

Polyamines, such as diethylenetriamine [111 0-0] are used at times ia the syathesis of microporous weak base resias to achieve significantly higher capacity. However, these resias geaerally have lower physical and chemical stabiHty than resias prepared from primary or secoadary amines. 

There are vastly more complex examples of difficult vectorization decisions. A great deal of effort has been devoted to writing vector code, or code that compilers can safely translate into vector instmctions. As compilers become more sophisticated, their ability to recognize vectorization opportunities increases. The vendors of vector computers often claim that vectorization is automatic and that end users need not be concerned with it. This claim is usually tme only if the end user is similarly unconcerned with achieving maximum performance. More often than not, codes that have not been written for vector architecture machines must undergo substantial restmcturing in order to achieve significant performance enhancements on vector-architecture machines. 

The CAAA90 offers a comprehensive plan for achieving significant reductions in emissions of hazardous air pollutants from major sources. The new law will improve EPA s ability to address this problem effectively and it will accelerate progress in controlling major toxic air pollutants. 

The EEA aims to support sustainable development and to help achieve significant and measurable improvement in Europe s environment by providing timely, targeted, relevant and reliable information to policy making agents and the public. The home page of EEA has links to environmental agencies in 26 European countries. 

In the last few years, methods based on Density Functional Theory have gained steadily in popularity. The best DFT methods achieve significantly greater accuracy than Harttee-Fock theory at only a modest increase in cost (far less than MP2 for medium-size and larger molecular systems). They do so by including some of the effects of electron correlation much less expensively than traditional correlated methods. 

The dry cell was invented by Leclanche in the 1860s. This type of battery was developed in the 19th century. In the 1940s, Rubel achieved significant progress in alkaline-zinc batteries, and manufactured zinc powder with high surface area to prevent zinc passivation. 

One may envisage polymerizations analogous to the thiol-enc process using other bis- or multi transfer agents (e.g. radical-induced hydrosilylation between bis-silanes and dienes). However, none has been described or achieved significance. 

There are relatively few other reactive groups which react by nucleophilic addition and which have achieved significant commercial success. However, one particular system which is worthy of note is the a-bromoacrylamido group, found in the Lanasol dyes (Ciba), which are among the most widely used reactive dyes for wool. The chemistry... 

Typically, only those sites that have aerobic conditions in the contaminated zone because of shallow water tables and high rates of groundwater recharge have achieved significant natural biodegradation of MTBE and other oxygenates.65... 

Brazilian cement plants are relatively modem due to the country s more recent industrialization in comparison with many other countries. For example, the average energy consumption per tons of cement produced in Brazil is 112 kWh/t, while in the United States this is around 140 kWh/t. The efforts of companies in the sector have achieved significant progress in terms of more efficient production systems with lower energy consumption. At the same time, the use of additives mixed with clinker, such as blast furnace slag, also has helped reduce C02 emissions per tonne of cement, because this pollutant is formed during the production of clinker. 

Practically wastewater reuse in another cleaning cycle can only be done in steps two, three and four. The water from the first step has a very high contaminant concentration, and reuse of this water in another cleaning operation would not achieve significant wastewater reductions. The wastewater from the other three steps has relatively low concentrations of contaminants and reuse of the water is feasible. In the application of the derived methodologies to the case study, the last three steps were modelled as one processing step. 

However, as the negative animal welfare impact associated with caged and other intensive indoor production systems became apparent, animal welfare became a primary driver for consumer demand and product differentiation in the poultry sector. As a result, both organic and conventional free range products have achieved significant market shares and price premiums compared to products from intensive indoor production in most European countries (Hamm et al., 2002). 

A photonic realization of qubit can be obtained through the polarization state of a photon or usingthe continuous phase and amplitude of a many-photon laser beam [5,48]. At first, the difficulty in achieving significant photon-photon interactions necessary for multi-qubit operations can be seen as a drawback of this proposal. However, it was demonstrated that scalable QC is possible using only linear optical circuits and single-photon sources and detectors [16]. The method (known as the KLM scheme for Knill, Laflamme and Milburn) [49] uses quantum interference with auxiliary photons at a beam splitter as the source of interactions, and has...
