    Beschreibung / Inhaltsverzeichnis: Résumé Cette étude comporte un essai de définition de l'apex du cœur et une présentation d'une classification en 3 types: l'apex « anatomique », dont la base est délimitée par l'incisure de l'apex du cœur, l'apex « anatomique élargi », occupant le double volume du précédent et l'apex « géométrique », occupant le tiers distal des ventricules. La vascularisation de ces 3 types d'apex cardiaque par les branches superficielles des artères coronaires, est précisé. Ce travail a été effectué sur 81 cœurs normaux (56 hommes et 25 femmes) dont 60 Caucasiens et 21 non Caucasiens. Les artères ont été injectées avec un mélange de gélatine colorée et de substance radio-opaque. Le nombre des rameaux artériels va en décroissant depuis le type géométrique (le plus volumineux) jusqu'à l'apex anatomique (le plus petit): 27 sont retrouvés à la surface de l'apex géométrique, 14 à la surface de l'apex anatomique élargi et 7 seulement au niveau de l'apex anatomique. Des différences selon le sexe ont été observées au niveau du rameau postérieur du ventricule gauche qui est retrouvé plus souvent chez les hommes que chez les femmes pour les apex anatomiques élargis. Pour les apex géométriques, 3 branches sont également plus fréquentes chez les femmes: le rameau antérieur et inférieur du ventricule gauche, les branches I et IV du rameau postérieur et latéral du ventricule gauche.
    Notizen: Summary The cardiac apex was defined and 3 types were presented: the anatomical apex, the base of which was established at the incisura apicis cordis; the amplified anatomical apex, twice the volume of the preceding; and the geometric apex, the distal third of the ventricles. These types of cardiac apex were studied in connection with the superficial branches of the coronary series at their level. The investigation was conducted on 81 normal hearts (56 males and 25 females) of 60 Caucasian and 21 non-Caucasian individuals. The arteries were injected with colored gelatine mixed with a radiopaque substance. The number of branches decreased from the geometric (the largest type) to the anatomical apex (the smallest): 27 on the surface of the geometric apex, 14 on the surface of the amplified anatomical apex, and 7 on the surface of the anatomical apex. The sternocostal aspect had a higher number of superficial branches than the diaphragmatic aspect in all types of cardiac apex. Sexual differences were found in the incidence of the r posterior ventriculi sinistri intermedius on the amplified anatomical apex as it was more frequent in females than in males. In the geometric apex there were 3 branches also more frequent in females: r anterior ventriculi sinistri inferior, r posterior ventriculi sinistri lateralis I, and r posterior ventriculi sinistri lateralis IV.

    Notizen: Abstract Six cultivars and breeding lines of potato (Solanum tuberosum) differing in susceptibility to verticillium wilt caused by Verticillium dahliae were studied with respect to quantitative and qualitative differences in the bacterial flora of their soil and rhizosphere-rhizoplane. Although, no association was observed between the types of bacteria that inhabited the soil or roots of wilt resistant and susceptible cultivars, quantitative differences were evident. These differences provide the first direct evidence that potato genotypes can influence bacterial populations. Bacterial populations were 9–25-fold higher on roots than in the adjacent soil. As the plants aged, the total number of rootcolonizing bacteria increased between 15 and 245%. Pseudomonas spp. were the most abundant microbes in the soil and rhizosphere-rhizoplane. The bacteria antagonistic to V. dahliae in vitro were identified as members of the genera Bacillus, Pseudomonas, Flavobacterium, and Gluconobacter. A statistically significant trend was evident toward the association of antagonistic bacteria with the more resistant potato cultivars.

    Notizen: Summary Activated sludge was successful in reducing the levels of dissolved organic carbon (DOC) in coal slurry wastewaters. DOC removal by the activated sludge ranged from 61% to 97% with a large percentage (21–41%) of this DOC being completely metabolized to CO2. Second order kinetic constants (k 2) developed for DOC removal ranged from 1.39·10−4 to 2.30·10−1 liter·day−1·(mg of sludge)−1, providing evidence that biological treatment was an effective mechanism for reducing the pollution potential of the slurry wastewaters. After treatment with activated sludge a residual DOC remained in the wastewater and data from ultrafiltration studies indicated that this residual carbon was of MW〉1000. The activated sludge preferentially removed the lower (MW〈1000) molecular weight compounds and the higher molecular weight DOC was more resistant to biological attack. However, extended acclimation (greater than 1 month) enabled the activated sludge to remove the higher molecular weight DOC from the slurry wastewaters.
