The source of O(1D) atoms in the auroral ionosphere is investigated using sounding rocket data. Previously, it has been shown that the conventional sources of O(1D) atoms in the aurora, dissociative recombination of O2(plus) and electron impact excitation of atomic oxygen, fail to explain the measured 6300 A volume emission rate profile. It is suggested that the atom-atom interchange reaction of N(2D) with O2 can be the major source of auroral 6300 A emission if O(1D) is created with high efficiency. [less ▲]

Steroid-16α-hydroxylase activities have been measured in normal and induced rat livers using four different substrates. The male/female activity ratio as well as the induction factor vary with the substrate indicating that steroid-16α-hydroxylase activity is a heterogenous enzyme. Experiments using specific inhibitors led to the conclusion that steroid-16α-hydroxylase is supported by at least two cytochrome P-450 forms, different from the cytochrome P-448. [less ▲]

A weakly pre-twisted beam theory is presented by an original way which renders the mathematical developments fairly simple. The proposed approach has the interesting property that in the finite element frame, the error of the theory converges to zero when the mesh is refined. [less ▲]

Four occasional measurements of the altitude distribution of the 2796-2803-Å doublet equatorial airglow have been made with the astronomical TD-1A satellite during winter 1973-1974. The observations indicate the presence of layers of Mg[SUP]+[/SUP] ions in the evening twilight F region in the African sector. Horizontal column densities reaching 8×10[SUP]9[/SUP]Mg[SUP]+[/SUP] ions/cm[SUP]2[/SUP] are observed with peak altitudes varying from 230 to 480 km. Steep topside gradients with scale heights of about 5 km are observed on three occasions. [less ▲]

La dendrométrie est une science qui consiste à mesurer les arbres et les peuplements forestiers ; à ce titre, elle occupe une position charnière d'une part entre les études fondamentales du milieu et la sylviculture et, d'autre part, entre la sylviculture et la planification ou l'utilisation des ressources boisées. La dendrométrie concerne l'activité de production de l'écosystème forestier et plus spécialement celle des arbres, son rôle habituel étant de mesurer ou d'estimer la production utile des forêts. Celle-ci ne représente cependant qu'une fraction de la production primaire totale ou de la productivité, mais en s'orientant depuis peu vers l'estimation volumétrique et pondérale des diverses composantes ligneuses de l'arbre, la dendrométrie moderne assure aussi une liaison particulièrement utile avec les études très actuelles de biomasse. Cette science forestière de base a un champ d'action relativement étendu, elle joue un rôle important dans le contexte de la gestion des ressources naturelles et de la formulation des mécanismes régissant l'évolution d'une forêt. Depuis une quinzaine d'années elle a d'ailleurs pris un essor considérable suite à une plus grande et meilleure utilisation des méthodes statistiques alliée au prodigieux développement de l'informatique. Les études dendrométriques s'appuient souvent sur des fondements statistiques et requièrent un bagage mathématique satisfaisant mais, pour avoir un sens, elles sont et restent fondamentalement tributaires de la connaissance des lois biologiques et des milieux écologiques. Le sujet traité étant particulièrement vaste, par souci de clarté, nous nous limiterons volontairement à l'exposé des bases, du rôle et de l'intérêt de la dendrométrie ; à cet effet nous envisagerons les buts et la spécificité des mesures dendrométriques ainsi que la nature de ces mesures tant pour les arbres que pour les peuplements, nous évoquerons les principales méthodes utilisées en vue de l'estimation de la production forestière et nous formulerons quelques considérations relatives à l'intérêt et à l'importance que revêt la dendrométrie en matière d'étude de productivité des milieux forestiers.

Streptococcus faecalis ATCC 9790 possesses six membrane-bound, penicillin-binding proteins. That numbered 6 (Mr 43000) is the most abundant one and is the DD-carboxypeptidase studied previously. The enzyme has been solubilized and purified to the stage where one single protein band can be detected by gel electrophoresis. The purification procedure does not alter the properties that the enzyme exhibits when it is membrane-bound. The DD-carboxypeptidase itself may be a killing target for penicillin in S. faecalis.

Automated computer systems can be developed not only to analyze Rorschach data, but to serve as other valuable research instruments. Selection, definition, and coding of information permit not only its memorization, but also analysis according to various mathematical methods. Tabulation and frequency analyses are facilitated, while other analyses (discrimination analysis, inverse factor analysis, covariance analysis) are made possible. The collaboration of psychologists, mathematicians, and computer specialists opens interesting avenues. [less ▲]
