| Uma série de três ensaios com nove inseticidas diferentes foi realizada para estudar seus efeitos sôbre o contrôle do tripes vector de vira-cabeça. Granutox-5, aplicado no solo, Folidol 60 (0,25%) e Dieldrex 20. (2,0%), em pulverizações foliares, apresentaram os melhores resultados; Metasystox (i) (0,4%) e Phosdrin C. E. 2 (1,0%), em pulverizações, também foram bastante promissores para o contrôle da moléstia. À redução na porcentagem de infecção com a moléstia nos melhores tratamentos não correspondeu grande aumento de produção, em comparação com a testemunha. Isto foi atribuído, em parte, ao efeito fitotóxico de alguns inseticidas, uma vez que foram aplicados em concentrações bem mais elevadas do que as recomendadas pelos fabricantes. |

| A fim de estudar o comportamento de tubérculos de batatinha - Solanum tuberosum L. - cortados em diferentes épocas após a colheita e submetidos a diferentes ambientes durante o armazenamento, foram feitos quatro, ensaios de caráter preliminar, com material de diferentes procedências. Foram plantados em Campinas, onde a altitude aproximada de 600 m não é recomendada para essa operação. Em dois dêsses ensaios foram comparados cortes longitudinais e transversais e em outros dois, sòmente no sentido longitudinal. Compararam-se produções, falhas, desenvolvimento das plantas etc, de tubérculos cortados logo após a colheita e antes da brotação, com os mesmos dados dos tubérculos cortados depois de brotados, pouco antes do plantio. De modo geral, não houve... |

| Critical Path Planning and Scheduling is a labour management aid considerably in advance of those previously available. First devised for the U.S. Navy in 1958, it divides project programming into two phases planning, and scheduling. In the planning phase a graphic representation of all activity relations is obtained by constructing an arrow network diagram. In the scheduling phase, duration times are assigned to activities and the three floats (spare time) available to each are computed. This allows the determination of the critical path of the project. Variable activity duration times and associated costs can also be handled. The techniques of Critical Path Planning and Scheduling are described in Section 3. The discussion, however, is confined to... |

| Lorsqu'il faut se contenter d'espaces restreints, comme c'est le cas dans le bâtiment des singes du jardin zoologique d'Anvers, il peut arriver facilement que des représentants de différentes espèces soient logés dans une même cage. Ce fut entre autre le cas d'un mâle cercopithèque mona, Cercopithecus mona mona (Schreber), et d'une femelle singe argenté, Cercopithecus mitis doggetti Pocock (anciennement l'espèce était connue sous le nom C. leucampyx Fischer). Cette dernière avait été accouplée auparavant à un mâle de la même espèce; le jeune qui vint au monde ne vécut que 44 jours; lorsqu'il naquit, son père était déjà mort. La femelle qui survécut fut placée auprès d'un cercopithèque mona très robuste, de sorte qu'il fut ainsi possible d'exposer les deux... |

| Au cours de ce travail, nous nous sommes efforcés de rendre compte des principaux caractères de l'ostréiculture méditerranéenne, particulièrement dans l'étang de Thau, en situant le plus exactement possible les taux de croissance observés, les rendements obtenus et les principaux facteurs qui influencent cette croissance. De cette étude, il se dégage que l'étang de Thau constitue un milieu particulièrement favorable à l'élevage des huîtres. Cependant, nous avons vu que le taux de croissance présentait des variations locales importantes : excellent en de nombreux points, il n'est que moyen en beaucoup d'autres. La principale cause de ces différences doit être attribuée à une mauvaise répartition des éléments nutritifs, due elle-même à une concentration... |

| De Candolle (1830) divided the genus Campanula into two large sections on basis of the presence or absence of calyx-appendages between the calyx-lobes. Boissier (1875) attached great value to the mode of dehiscence of the capsule, and divided the genus into two sections. None of the existing classifications seems to be a natural one. As cytological investigations and crossing experiments might give valuable information for a natural classification, it was decided to investigate: a. The classification of the species within the genus Campanula based on morphological, cytological, and genetic data. b. The variability of a number of species, based on cytological investigations and growing experiments carried out under uniform conditions. In Chapter I a survey... |

Tomes 1-10, 1910-1922”, several publication dates of the parts of French works could be stated with more certainty.

| In het standaardwerk „Die Säugetiere" van Max Weber (1904) treffen wij op p. 550 de taxonomie aan van de Trichechidae, welke thans Odobenidae worden genoemd. Op genoemde pagina lezen wij: „Pliocäne Reste aus England und Belgien beweisen die frühere grössere Verbreitung". Pliocene overblijfselen uit ons land waren dus in 1904 blijkbaar nog niet bekend. In 1906 werd in Nederland de eerste duidelijke aanwijzing gevonden van een fossiele Odobenus. Een visser vond toen namelijk tegenover Breskens, Zeeuwsch Vlaanderen, in de Wester-Schelde een schedel met de beide slagtanden. Hieronder hoop ik op deze en dergelijke vondsten terug te komen. In 1927-1928 kwam de tweede druk van „Die Säugetiere" uit; Weber had zich toen verzekerd van twee medewerkers, O. Abel en H.... |

| This paper gives a survey of the forms of Scorpiurus muricatus L. In contradistinction to Thellung who distinguished in his “Flore adventice de Montpellier” 4 subspecies, the present authors subdivide the species into 2 subspecies, each with some varieties. They can be identified with the aid of the following key. In using this key, one must be aware of the fact that several transitions between the subspecies and the varieties exist. 1. Calyx-teeth triangular, shorter than to about as long as the tube. Pod loosely coiled, almost in one plane. Ribs of pod all smooth or only the outer ones muricate or spiny; spines stout, at most as long as the diameter of the pod. Seeds mostly slightly curved subsp. muricatus 2. Ribs of pod all smooth ........... var.... |

| De soorten van het genus Cyphon Paykull, vooral die uit de verwantschap van C. variabilis (Thunberg), zijn zeer moeilijk op uitwendige kenmerken te determineren. Dit kan eigenlijk alleen met verse of zeer schoon geprepareerde exemplaren. Goede kenmerken zijn echter te vinden in de copulatieorganen 1), zowel bij de mannelijke als bij de vrouwelijke individuen. Bij de mannelijke organen ziet men in ventraal aanzicht de volgende onderdelen (fig. 1) : het negende sterniet (s), de ventrale (ν) en de dorsale (d) plaat van de aedeagus, en daarnaast, bij de meeste soorten, de staafvormige zijkanten van het achtste en negende tergiet (t). Bij het vrouwtje bezit de „prehensor", een chitineus orgaan in de vagina dat dient om de spermatophoor op te nemen, goed... |
