In the classical case, the evolution of the kicked rotor dynamics is described by the well-known standard map (Chirikov, 1979). This map greatly facilitates the qualitative treatment of the system. A map describing the evolution of the wave function can be obtained in the quantum case, too (Casati et.al., 1979). In spite of the fact, that the first work with detailed treatment of the quantum kicked rotor appeared 23 years ago (Casati et.al., 1979), this system is still studied extensively (Casati et.al., 1987 Izrailev, 1990). 

In 1962, while still studying at the Stroganov School, Kosmatschof began teaching art at a People s University , a kind of open university for students from the distant provinces of the Soviet imperium he taught at this institution until 1968. There he built up... 

As you know, Dalton s atomic theory no longer applies in its original form, and Mendeleev s periodic table has undergone many changes. For example, scientists later discovered that atoms are not the most basic unit of matter because they are divisible. As well, the modern periodic table lists the elements in order of their atomic number, not their atomic mass. Of course, it also includes elements that had not been discovered in Mendeleev s time. Even so, in modified form, both of these inventions are still studied and used today in every chemistry course around the world. 

Of course, we do not think that we have completely solved the puzzle of the taste tetrahedron. We are still studying saltiness of 0-aminoacyl sugars although we have not found even a piece of the answer to a saltiness mechanism for these compounds. The most serious problem, which we have to solve first, is why we have been unable to design 0-aminoacyl sugars fiom which salty potency is stronger than that of sodium... 

Traditionally, solid acidic catalysts are applied in industry for the oligomerization of butenes and are still studied. MTS-type aluminosilicates,522 a NiCsNaY zeolite,523 and a silica-alumina containing 13% alumina524 proved to be active and selective catalysts. Moreover, deactivation rates of these catalysts are also favorable. Sulfated zirconia promoted with Fe and Mn was active and selective to yield primarily dimethylbutene isomers under supercritical conditions.525 A small amount of water improved productivity and decreased deactivation. A study showed that the blending octane number of Cg hydrocarbons is directly linked to the number of allylic hydrogens in the molecules.526... 

The reader may ask, "How can we study awareness or consciousness when we don t know what it basically is " The answer is, "in the same way that physicists studied and still study gravity they don t know what it is, but they can study what it does and how it relates to other thinqs."(back)... 

In the Ga2S3-MnS system, we observed several definite compounds between the compositions 2Ga2S3-MnS and Ga2S3-MnS. The compound MnGa2S4 has three polymorphic modifications. We are still studying this region. 

In this case we can incorporate the consumption of the reactant and still study (true) steady-state behaviour. Setting d[A]/dt = d[A /dr = 0 we obtain... 

However, the two major branches of chemistry are still studied separately. This is because there is a useful distinction to be drawn between the two. Yet, this distinction is no longer based on the presence or absence of a vital force, but rather is partly derived from the practical consequences of the stability of the homoatomic carbon/carbon bond. One such consequence is that the chemistry of carbon-containing compounds often involves the study of molecules that contain many such bonds. Thus, because of the multitude and variety of these compounds, it is convenient to study them separately. In contrast, inorganic chemistry is often concerned with the structure and utility of molecules that contain heteroatomic bonds, either ionic or covalent. This means that in an inorganic molecule, there are often two or more elements that could be said to be of equal prominence. In addition, there still remains the point that carbon compounds form the vast majority of the constituent components of living beings, while non-carbon compounds comprise the environment in which those beings exist. So the distinction is the same, but the justification is different. 

In 20 years, do you think scientists will still study biology in a laboratory— or will they just do everything on a computer Give a reason for your answer. 

The 2-pentenenitrile, 2-methyl-3-butenenitrile, and methylglutaronitrile in Figure 1.1 are by-products of this reaction sequence. duPont is still studying the phosphines used as ligands for the nickel in an effort to find one bulky enough to favor terminal addition only.214 Reduction of the various nitriles leads to the amines in Figure 1.1, including the cyclic ones. The 2,3-dichloro-l,3-buta-diene is probably a by-product in the synthesis of 2-chloro-1,3-butadiene used to make Neoprene rubber. duPont also polymerizes acrylonitrile to prepare poly (acrylonitrile) fiber (Orion). Acetonitrile is obtained as a by-product of the ammoxidation of propylene to produce acrylonitrile (reaction 1.20). 

The activity of some Y zeolites showing different Lewis and Bronsted acid sites density is still studied in the acylation of dimethoxyarenes (with particular attention to veratrole. Scheme 4.7) with different acyl chlorides as a function of zeolite acidity and the lipophilic nature of acyl chlorides. Because of the particularly soft reaction conditions, namely, 65°C and 1 h reaction, 3,4-dimethoxyphenyl ketones 12 are the sole isomers recognized in the reaction mixture. Results of the catalytic tests (yield of compounds 12) confirm that the best catalyst is Y(14), characterized by an optimum ratio between Lewis and Bronsted acidity (medium-strength acid sites density for Lewis and Bronsted acid = 17.0 and 11.0 mmol x g- py. 

Racheli 1 do not recall how you actually convinced me. But what attracted me for sure were the prospects of a unique experience to teach such a course to humanities and social science students. As you know, I play the piano and sing, and I still study chemistry. So it looked natural to me that anyone, even staunch artists, should learn chemistry. 

On further standing, the AD bisimidazole catalyst converts 14 into its dehydrated product 15 [13]. This process also involves enolization, of course, and we are still studying whether our two catalytic groups play other roles as well. For instance, they could promote the addition of the enol to the aldehyde group in the original condensation, or serve to promote the dehydration by using BH+ to... 

Percolation of capillary pores in cement paste. A few remarks are needed as a reminder that all the processes considered develop in highly disordered media. High porosity does not necessarily mean high permeability, because only interconnected pores represent channels for the possible flow of gases and fluids. The relationships governing the flow are linear only within narrow limits and more often high non-linearity should be expected. For basic information on percolation processes in strongly disordered media, the reader is referred to Mandelbrot (1982), but the application of the notion of percolation to cement-based materials is still studied by many authors.

This topic is still studied and in recent papers Thicket and Gilbert focused their investigations on the aspects concerning the mechanism of the emulsion polymerization, for both electrostatically and electrosterically stabilized particles [275,276] various kinetic limits has been described to explain an emulsion polymerization... 

In these models the odds are estimated for students who started flieir bachelor programme in 2006/07, 2007/08 and 2008/09. As there was hardly enough time for students to already have graduated by June 2010, we calculate the odds of whether a student who was still studying respectively graduated (coded 0) or dropped out (coded 1). About one fourfli (25.6 %) have already dropped out from VUT within the first three years of observation. As indicated in Table 2, the explained variance in this model is relatively low compared to the model for diploma students. We assume that... 

Still, study author Dr. Brad A. Racette of the Washington University School of Medicine in St. Louis said that, with more than a million welders in the U.S., a proven link between neurotoxic effects and manganese fumes would have a substantial public health impact for the U.S. workforce and economy. ...
