Impact of Pollution on Animal Products

The present workshop contributed highly to the exchange between scientists giving the opportunity for researchers from Central Asia to access to new scientific approaches and methodologies, and for European scientists to assess the extent of the environmental problems in this part of the world. No doubt that these exchanges were the main success of the workshop marked by very stimulating discussions. Such meeting was also the opportunity to put on the first stone of a scientific network focused on the subject of the workshop. The importance of pollution in Central Asia in general and in Kazakhstan in p- ticular is a well-known feature and several references are available on the source and localization of pollution problems in those countries. The references are also abundant on the impact of the environmental failures on human health.

Immobilisation of DNA on Chips II

DNA chips are gaining increasing importance in different fields ranging from medicine to analytical chemistry with applications in the latter in food safety and food quality issues as well as in environmental protection. In the medical field, DNA chips are frequently used in arrays for gene expression studies to identify diseased cells due to over- or under-expression of certain genes, to follow the response of drug treatments, or to grade cancers), for genotyping of individuals, for the detection of single nucleotide polymorphisms, point mutations, and short tandem reports, or moreover for genome and transcriptome analyses in the quasi post-genomic sequencing era. Furthermore, due to some unique properties of DNA molecules, self-assembled layers of DNA are promising candidates in the field of molecular electronics.the main focus of these two volumes is on the immobilization chemistry, considering the various aspects of the immobilization process itself, since different types of nucleic acids, support materials, surface activation chemistries and patterning tools are of key concern.

Immobilisation of DNA on Chips I

the main focus of these two volumes is on the immobilization chemistry, considering the various aspects of the immobilization process itself, since different types of nucleic acids, support materials, surface activation chemistries and patterning tools are of key concern.the focus of the major part of the chapters lies on the coupling chemistry used for DNA immobilization. Successful immobilization techniques for DNA appear to either involve a multi-site attachment of DNA (preferentially by electrochemical and/or physical adsorption) or a single-point attachment of DNA (mainly by surface activation and covalent immobilization or (strept)avidin-biotin linkage).

Hydroboration and Organic Synthesis : 9-Borabicyclo [3.3.1] nonane (9-BBN)

Borabicyclo [3.3.1]nonane, a commercially available reagent, is the most versatile hydroborating reagent to synthesize organoboranes (B-R-9-BBN). The reagent exhibits remarkable regio-, chemo-, and stereoselectivity during hydroboration reactions. The organoboranes can be converted to C-H, C-O, C-N, C-S, C-halogen, C-metal and above all C-C bonds. In addition, the suitable substituted / unsaturated R of B-R-9-BBN can be utilized to produce dienes, enynes, allenes etc. with defined stereochemistry. 9-BBN’s derivatives have been elegantly used for the asymmetric reduction of ketone moiety. Diels-Alder and Suzuki reactions have expanded the utility of 9-BBN for the synthesis of a variety of organic compounds required for industry. Consequently, this vast field in the form of a book will be helpful to synthetic organic chemists for easy access to literature, required for chemical transformations.

Hot cracking phenomena in welds

The first chapter provides an overview of the various hot cracking phenomena. Different mechanisms of solidification cracking proposed in the past decades are summarized and new insight is particularly given into the mechanism of ductility dip cracking. The effects of different alloying elements on the hot cracking resistance of various materials are shown in the second chapter and, as a special metallurgical effect, the initiation of stress corrosion cracking at hot cracks has been highlighted. The third chapter outlines how numerical analyses and other modelling techniques can be utilized to describe hot cracking phenomena and how such results might contribute to the explanation of the mechanisms. Various hot cracking test procedures are presented in the final chapter with a special emphasis on standardization. For the engineering and natural scientists in research and development the book provides both, new insight and a comprehensive overview of hot cracking phenomena in welds.

Heterogeneous Enantioselective Hydrogenation : Theory and Practice

The book looks at the first relatively ineffective catalysts right through to modern highly effective enantioselective catalytic systems, comparable in their efficiency to chiral metal complexes and enzymatic systems. The book begins with a summary of the first work on heterogeneous metal catalysts, which showed only the principal possibilities of enantioselective reactions. The book then elaborates on metal catalysts which have enantioselectivities close to 100%. Finally, the book describes the practical utilization of chiral catalytic systems in processes of hydrogenation. The a - and b -hydroxy carboxylic acid esters produced are precursors for manufacturing many synthones used for medicines as well as for monomers used for biodegradable polyesters, both of which have important practical applications. The book summarizes more than 800 scientific papers in the field of enantioselective catalytic hydrogenation reactions, mainly those using heterogeneous metal catalysts. It provides detailed explanations of special techniques for the preparation of effective dissymmetric catalysts which provide highly efficient catalytic systems.
