title: Synthesis and elastase inhibition activities of novel aryl, substituted aryl, and heteroaryl oxime ester derivatives
abstract: Fifteen novel aryl, substituted aryl and heteroaryl g hydroxy (2a e) g methoxyimino (3a e) and g benzyloxyimino (4a e) butyric acid methyl esters were investigated for their enzyme inhibition, and the synthesis of 10 compounds (3a e, 4a e) is given in this study. The other five compounds (2a e) were synthesized before in another study. Compounds 3a e and 4a e were synthesized in this work as original compounds and characterized by 1H and 13C NMR, IR, mass, and elemental analyses. Their (E/Z) isomerisation ratios were analyzed by 1H and 13C NMR. All of them are of pure (E) configuration. Due to the literature survey, the elastase inhibition activity was not studied for these compounds. Elastase inhibition ability was investigated in this work for five g hydroxy (2a e) five g methoxy (3a e) and five g benzyloxyimino (4a e) butyric acid methyl esters. All these 15 compounds showed elastase inhibition activity. Compound 2b was the best one and exhibited a better activity than the standard ursolic acid whereas compound 2a worked like the standard. All these compounds can be novel elastase inhibitor agents in the pharmaceutical and cosmetic industries.

title: Different bio/Lewis acid catalyzed stereoselective aldol reactions in various mediums
abstract: In this work eight different crude biocatalysts together with six Lewis and three Bronsted acids were used for asymmetric aldol reactions of aromatic, heteroaromatic, cyclic, and acyclic six ketones and eleven aldehydes. Optimum reaction conditions were determined by changing temperature and enzyme, ketone, aldehyde, solvent, cofactors types, amounts, and ratios. PPL (porcine pancreatic lipase) of animal and AL AN (amano lipase A from Aspergillus niger) of fungal origins were the best ones and compared with each other. CoCl2 was the best cofactor and catalyzed the enzymatic aldol reaction better than without cofactor. CoCl2 was not used before for enzymatic aldol reactions. The method in this study, using crude biocatalysts (PPL or AL AN) and CoCl2 in acetonitrile water was found as an conventionally useful biocatalytic way for asymmetric aldol reaction and has given better ee values than in the literature.

title: An Air Cooled YASA Motor for in Wheel Electric Vehicle Applications
abstract: In wheel motors present a range of opportunities for innovation in electric vehicle design as the torque produced at each of two or four wheels can be controlled individually. A high aspect ratio (large radius, short axial length) motor is required to fit within the wheel. Due to its location, liquid cooling of the in wheel motor is difficult and undesirable, but a high power density is required to reduce the mass which is particularly important as it is unsprung and fit the space envelope. Furthermore, a high torque density is required to eliminate the need for a gearbox. These constraints create a real challenge for the design of a machine for this application. An axial field machine using a Yokeless and Segmented Armature (YASA) topology is designed to fit these requirements as such a machine has clear advantages when considering the high aspect ratio. A soft magnetic composite (SMC) material is utilised to carry the flux in its non planar path without incurring excessive losses or requiring an impractical and difficult to manufacture lamination design. A novel cooling arrangement involving heat spreading elements on each armature segment is employed to improve heat dissipation and hence power density. The design, analysis, manufacturing and testing of the motor is described in this paper to verify the concept against the requirements outlined above.
