[more ▼] Initial bound activity of β -galactosidase, immobilized on Sepharose activated with CNBr or coupled to porous glass beads, was 51 and 72% resp. of the free enzyme activity. The enzyme retained its activity after 80 h of continuous operation using milk. Initial activity of chymosin coupled to glass beads was only 8-10% but rose to 38% when protected by an inert protein. Only 40% of initial activity was retained after 1 h continuous exposure to milk.

[more ▼] Le gestionnaire forestier doit prévoir à long terme et organiser à court terme, à cet effet il doit avoir une connaissance aussi précise que possible des potentialités des massifs forestiers. La répartition des zones boisées et des peuplements en classes de productivité joue un rôle déterminant dans le choix des essences à favoriser ou à introduire, ainsi que dans la prévision de la production des peuplements. Cette répartition s'appuie généralement sur l'utilisation d'indices de productivité entre autres établis à partir de méthodes quantitatives ; parmi celle-ci la hauteur dominante atteinte à un âge donné est très intéressante à considérer. Son utilisation nécessite cependant certaines mises au point (relation avec la production totale, nuances d'interprétation selon la stucture des peuplements, etc...). L'approche "factorielle" (indices de productivité mixtes) est sans aucun doute la plus complète et la plus à l'honneur aujourd'hui grâce à l'utilisation croissante de l'informatique ; elle permet d'identifier la productivité sur la base d'une combinaison d'indices écologiques et dendrométriques. Cette méthode doit permettre l'établissement de listes de critères simples, codifiables et synthétiques, de plus elle présente l'incontestable intérêt d'aborder le problème de la productivité forestière sous un angle pluridisciplinaire.

[more ▼] Stand volume tables of Norway Spruce (Picea Abies Karst.) in "Southern Ardennes" have been established in order to estimate directly volumes per hectare. The use of such tables calls for preliminary measurements of the basal area and the top height. Compared to the tree volume approach, fewer measurements and computations are made with great savings in time and little loss in accuracy. The equations should be valid for many inventory purposes. Special attention should be given in future to stand volume equations for other species and local use.
