Overhead power lines with bundle conductors may be equipped without spacers. In such case overload may induce kissing phenomena or collapsing inside the bundle. This paper , following the first one published also in ELECTRA this year, is describing the final formulation of the kissing current level, validated by scale model and full scale test on unspacered twin bundle line in vertical arrangement.

The aim of this article is to highlight the recent changes in the industries of the Brussels' metropolis and to study the two forces which are face to face : the big movement of the exurbanisation of the activities and the strategy recently put in place by the Agglomeration of Brussels to maintain or receive a renovated field of industry. Although the case of Brussels is particular because of the political status of its sub-spaces, it is noretheless very interesting as there can be no doubt that the new relations between industry and a town are revealing.

The aim of this study is, initially, to compare the attempts at urban reintegration of certain industrial activities at the present time with the considerable ex-urbanisation movement of activities which has been evident since 1960. We then go on to analyse the strenghts and weaknesses of the two trends and seek to define the likely future of the processes and put forward a new urban strategy for a more efficient policy as to receiving certain activities in urban surroundings.

The recent evolution of self service stores and shopping centres in Europe can initially be summed up by three main quantitative factors : an almost general advance of super and hypermarkets, a decline in small self service units and the multiplying of shopping centres. However, the impact of these new kinds of sales outlets is by no means the same in every country. Furthermore there have been many variations in the concept of shopping centre since 1975. [less ▲]

The tobacco plant has been the object of extensive basic research about its genetic, culture, biochemistry and postharvest metabolism. In addition , much is known of its pyrolysis products and the conditions that affect the formation of these products. Tobacco smaoke is a concentrated aerosol of liquid particles suspended in an atmosphere consisting mainly of nitrogen, oxygen and CO2. While the precise chemical composition of the particular and gaseous phases is depended on the characteristics of commercial tobacco and the manner in which it is smoked, both phases contained tens of hundreds of individual constituents. Notable among potentially hazardous constituents of smoke are tar (mainly benzopyrene) nicotine, HCN, acrolein, N-nitrosamines, cadmium and polonium 210. recent advances in tobacco science make it possible to develop a safer tobacco that delivers undesirable smoke compounds at levels that are below the old values, but these results are biologically uninterpretable at present.

The originally penicillin-induced, wall-less stable L-forms of Proteus vulgaris P18, isolated by Tulasne in 1949 and since then cultured in he absence of penicillin, have kept the ability to synthesize the seven penicillin-binding proteins and the various DD- and LD-peptidase activities found in the parental bacteria and known to be involved in wall peptidoglycan metabolism. The stable L-forms, however, secrete during growth both the highly penicillin-sensitive, DD-carboxy-peptidase-transpeptidase penicillin-binding protein PBP4 (which in normal bacteria is relatively loosely bound to the plasma membrane) and the penicillin-insensitive LD-carboxypeptidase (which in normal bacteria is located in the periplasmic region).

The three-dimensional structure of a penicillin-sensitive D-alanyl-carboxypeptidase-transpeptidase has been determined by x-ray crystallography to a resolution of 2.8 angstroms. The site of binding of the beta-lactam antibiotics penicillin and cephalosporin has been located. These findings constitute direct observation of the interaction of beta-lactams with a transpeptidase enzyme and establish the feasibility of defining the molecular stereochemistry of this interaction for purposes of drug design.

The membrane-bound, 26 000-Mr penicillin-binding protein of Streptomyces K15 has been isolated in the form of an effective, penicillin-sensitive D-alanyl-D-alanine-cleaving peptidase exhibiting high transpeptidase activity (greater than 95%) and very low carboxy-peptidase activity (less than 5%). The penicillin-binding protein/transpeptidase can be extracted directly from the mycelium with N-cetyl-NNN-trimethylammonium bromide (Cetavlon) and subsequently obtained at 90% purity and with an 8000-fold specific enrichment (when compared with the activity of the isolated membranes) by a two-step procedure involving Sephadex filtration and affinity chromatography on ampicillin-linked CH Sepharose 4B in the presence of detergent. At saturating concentrations of the co-substrates diacetyl-L-Lys-D-Ala-D-Ala and Gly-Gly, the catalytic-centre activity is about 0.3 s-1. [less ▲]
