Lipases as Biocatalysts in Organic Media. Influence of Enzyme Preparation and Reaction Conditions on Activity and Selectivity

The discovery that enzymes can function in organic solvents has broadened the scope of biocatalysis, making enzymes highly useful tools for organic chemists. The widespread use of enzymes as catalysts in organic solvents has, however, been limited by the low activity obtained for enzymes in organic solvents compared to aqueous solutions. The increasing demand for optically pure enantiomers in phar

Explanations are about concepts and concept formation

In this paper, I wish to argue that an explanation is not a logical structure¸ that it cannot be characterised in syntactic terms, but that it is rather an epistemological structure, and, more specifically, a structure organising conceptual content. I will start from a trivial example and systematically look at the effects of making premises more general or more specific or of reshuffling the same

Robust Initial LLRs for Iterative Decoders in Presence of Non-Gaussian Noise

We consider the decoding of LDPC codes in presence of non-Gaussian noise, especially a set of ¿-mixture models. For each of these models, the optimal LLRs are presented. We study the performance degradation due to the use of incorrect LLR in presence of a given noise model. Without modifying the existing LDPC decoder, we propose robust initial LLR which require minimum knowledge about the underly

Interlaboratory tests on thermal foot models

A limited Round Robin test has been carried out with different types of foot models. Eight laboratories carried out the tests. The foot models varied in sizes from 254 to 275 mm, representing boot sizes from 41 to 44. Tests with both a bare foot and sock were carried out at about +20 °C and 50% RH. The boots, a thin rubber and a winter boot, were tested at about +5 °C and 85% RH. The conditioning

Pondering on methods. A variety of methodological concerns

In this book, ten doctoral students share and discuss a number of metho- dological concerns they have faced in the process of doing research. In the first part, “Capturing the field,” the contributors grapple over issues regarding how to define and demarcate the field of research, for instance in studies on immigrant organizations, red light districts on the Internet, and telephone interviewing. I

Off-line analysis of the load response during large voltage variations

The load response during and after a severe fault is critical for transient stability. This risk increases with the presence of induction motors in the load area. This paper provides analysis of the load voltage characteristic under large voltage variations. Field measurements from a noneffectively earthed system, from phase-to-phase faults at the 50 kV-level in Sweden, have been used. The time-va

Psycho-vibratory evaluation of timber floors

In lightweight constructions using timber floors, vibrations can cause some inconveniences and nuisances for the inhabitants. In order to have a better estimation of an acceptable level of vibrations in dwellings, more studies addressing human response to vibrations are needed. In the study presented in this paper, measurements have been performed on five real floors in a laboratory environment. D
