    Notes: [Auszug] Recently4 the chemisorption of hydrogen by copper has been examined calorimetrically and volumetrically and the equilibrium surface coverage was found to be at a value of q = 0.15, where the heat of adsorption was determined as 10 kcal/mole. Confirmation of these values has been obtained in the ...

    Description / Table of Contents: Résumé Des génisses Ndama pesant initialement 129 kg à l'âge approximatif de 30 mois, ont reçu un supplément de 250, 500 ou 1000 g par tête et par jour de tourteau d'arachide pendant 3 ou 6 mois durant la saison sèche ou les saisons sèche et humide. On a ainsi obtenu des améliorations hautement significatives des taux de gain en poids vif et des performances de reproduction. La supplémentation pendant la seule saison sèche a triplé, en chiffres approchés, la proportion des mises bas dans les deux ans qui ont suivi le début de l'expérience (6% contre 20% avecP〈0,05). L'augmentation a été de l'ordre de 8 fois supérieure chez les animaux qui ont continué à recevoir la supplémentation pendant la saison humide (6% contre 50% pourP〈0,05). La conception est intervenu au poids vif moyen général de 185 kg. L'objectif est un poids vif de 200 kg pour la première fécondation des génisses Ndama, comme base des recommandations pour l'élevage de ces animaux. En conclusion, une telle intervention peut réduire de 12 mois l'âge observé habituellement à la première mise bas chez des génisses Ndama élevées en milieu villageois, et ceci d'une manière àla fois pratique et financièrement avantageuse.
    Abstract: Resumen Vaquillas N'Dama que inicialmente pesaban 129 kg a los 30 meses de edad, fueron suplementadas con 250, 500, ó 1000 g/cabeza/día con torta de nueces molida, durante 3 ó 6 meses durante la estación seca o seca y húmeda. Se obtuvieron ganancias significativas en peso y eficiencia reproductiva. La suplementación durante la estación seca únicamente, triplicaron la proporción de animales que parieron dentro de los dos años del inicio del ensayo (6 Vs 20%,P〈0·05), mientras este incremento fue cerca de ocho veces en los animales que continuaron reciviendo el suplemento durante la estación lluviosa (6 Vs 50%,P〈0·05). Las paraciones ocurrieron a un peso medio general de 185 kg siendo el objetivo propuesto un peso de 200 kg para la primera parición de Vaquillas N'Dama. Se concluye, que este tipo de intervención puede reducir la edad al primer partoa 12 meses, siendo el manejo práctico y económicô meute ventajoso.
    Notes: Summary N'Dama heifers, initially weighing 129 kg at approximately 30 months of age, were supplemented with 250, 500 or 1000 g/head/day groundnut cake for 3 or 6 months during the dry or dry and wet seasons. Highly significant improvements in rates of liveweight gain and reproductive performance were obtained. Supplementation during the dry season only, approximately trebled the proportion of animals calving within 2 years of the beginning of the trial (6 vs 20%, P〈0·05), while this increase was around eight-fold in the animals that continued to receive supplement during the wet season (6 vs 50%, P〈0·05). Conceptions occurred at an overall mean liveweight of 185 kg, and a “target” liveweight of 200 kg for the first conception of N'Dama heifers is proposed as the basis for husbandry recommendations concerning these animals. It is concluded that such intervention can reduce the usually observed age at first calving of village based N'Dama heifers by 12 months, in a fashion that is both practicable and financially advantageous.

    Description: Assessment methodology for squid fisheries is presented, extending previous work by considering migration between adjacent fishing grounds. The methods are based on standard Leslie-Delury analysis but make different assumptions about stock movement and the relation between stock abundance and catch per unit effort. The new methodology is applied to data from the Illex argentinus fishery in the Southwest Atlantic, south of 45 °S. Retrospective assessments for the 1987–1991 fishing seasons are presented, focusing on estimates of recruitment and spawning biomass. Management of the fishery around the Falkland Islands is based on effort control. The objective is to maintain the spawning biomass above a threshold level, thus avoiding high probabilities of low recruitment in the following season. The estimates of spawning biomass and recruitment from the analyses are used to estimate an appropriate threshold level of spawning biomass.

    Description: During the past decade, localization microscopy (LM) has transformed into an accessible, commercially available technique for life sciences. However, data processing can be challenging to the non-specialist and care is still needed to produce meaningful results. PALMsiever has been developed to provide a user-friendly means of visualizing, filtering and analyzing LM data. It includes drift correction, clustering, intelligent line profiles, many rendering algorithms and 3D data visualization. It incorporates the main analysis and data processing modalities used by experts in the field, as well as several new features we developed, and makes them broadly accessible. It can easily be extended via plugins and is provided as free of charge open-source software. Contact: thomas.pengo@gmail.com

    Description: We created a high-throughput modality of photoactivated localization microscopy (PALM) that enables automated 3D PALM imaging of hundreds of synchronized bacteria during all stages of the cell cycle. We used high-throughput PALM to investigate the nanoscale organization of the bacterial cell division protein FtsZ in live Caulobacter crescentus. We observed...
