REMARK system

Biosystems are remarkable systems for what they do. They can remove nitrogen, reduce phosphorous and remove it from wastewater, and destroy any wide variety of organic compounds by turning them into CO2 and water. However, they cannot create nor destroy matter. If you have toxics, you will need to handle the toxics in a pretreatment system or somehow dilute them down to the level where they can be treated. Metals are a particular problem because they bio accumulate even in bacterial systems. 

In the REMARK system, estimated effects (e.g., hazard ratios) with confidence intervals for the marker were recommended for univariant and key multivariable analyses, and a Kaplan-Meier plot was recommended to represent the effect of a tumor marker in a time-to-event outcome. The discussion section should interpret the results in the context of the pre-specified hypothesis and describe limitations of the study as well as implications for future research and clinical value. These guidelines were advocated for reporting of tumor marker studies in breast cancer research and treatment (63). 

The fundamental theme for this review was the attempt to illustrate the "flavor of current research in this area. If one were to summarize (62, 146) the present status of our knowledge of these remarkable systems, it might be that most of the properties of excess electrons in solution can be interpreted in terms of models that are (qualitatively) easily understood, but quantitatively evaluated only with considerable effort. This is, indeed, an observation pertinent not only to metal solutions, but to inorganic chemistry in general ... 

This estimate is independent of a particular location in phase space. This implies that all points of phase space, in particular the period-1 points, are linearly unstable. Thus we have proved that the positively kicked hydrogen atom does indeed not possess any first order eUiptic islands in phase space. It is possible to extend this proof to period-iV points and to show that all period-N points, N integer, are Unearly unstable (Bliimel (1993c)). This implies that the positively kicked hydrogen atom is completely chaotic. We emphasize that, as far as we know, the kicked hydrogen atom is the only model for a physically realizable system where a numerically motivated chaos conjecture was followed up by an analytical proof. In this sense the kicked hydrogen atom is a most remarkable system.

The present book consists of ten articles containing lecture notes written by the lecturers of the NATO AST The first article discusses general aspects of pattern formation and universal features of self-organization in non-equihbrium systems. The next two articles are devoted to pattern formation and nonlinear phenomena in liquid crystals - a most remarkable system in which nano-... 

A later variant involved incorporation of an oxidant, Pt(IV), which led to formation of functionalized species, RX, from alkane, RH. In the typical chloride-rich Shilov systems, X is commonly Cl and OH. The Pt(IV) oxidant is reduced to Pt(II) during the reaction, but it has proved hard to replace this expensive oxidant by a cheaper one while retaining activity. A remarkable system of this type discovered by Periana [109] uses cone. H2SO4 as both oxidant and solvent and a Pt(II) 2,2 -bipyrimidine complex as catalyst with the result that CH3OSO3H, a methanol derivative, is formed from methane. 

The genetic information that makes each organism s offspring look and behave like its parents is encoded in molecules called nucleic acids. Together with a set of specialized enzymes that catalyze their synthesis and decomposition, the nucleic acids constitute a remarkable system that accurately copies millions of pieces of data with very few mistakes. 

Differences in coordination number become significant in mixed oxide systems, where we find many examples of enhanced Lewis or Bronsted acidity, even for binaries such as Si02-Mg0. However, the best known and possibly most remarkable system of this type is silica-alumina. Typical materials have acid titres of the order 1 milliequivalent/g, but only a small proportion of the acid sites show — Hq values of 3 or more. 

In her studies on the /-block metals, Patricia Watson found a remarkable system in which successive alkene insertions into a Lu—R bond can be observed step by step (Eq. 11.62). Not only do the alkenes insert, but the reverse reaction, P elimination of an alkyl group, as well as the usual p elimination of a hydrogen, are also observed. For the d-block this p elimination of an alkvl erouo would normally not be possible it is probably the larger M—R... 

The remarkable system used by nature to convert sunlight into more useful energy equivalents is the source of inspiration for artificial photosynthesis - the development of synthetic systems that mimic the natural photosynthetic processes of light-driven water splitting and CO2 reduction, for the production of solar fuels. ...
