We studied the pattern of distribution of the common genet (Genetta genetta) in areas in mountains and plains of central Spain, in the middle of the range of the species. We evaluated the role of temperature, rainfall, and habitat features in determining the ecological limits of genet distribution. Genets were very scarce on plateaux and the upper parts of the mountains, but were widely distrib...

Anophryocephalus inuitorum sp.nov. and A. arcticensis sp.nov. are described from ringed seals (Phoca hispidu hispida) in the eastern Canadian Arctic; the latter species is also reported from harp seals (Phoca groenlandicu) in the Gulf of St. Lawrence. Anophryocephalus inuitorurn is most similar to A. skrjabini, but can be distinguished by fewer testes (14-27) and smaller dimensions of the strob...

In this note we present a way to approximate the Steiner problem by a family of elliptic energies of Modica-Mortola type, with an additional term relying on a weighted geodesic distance which takes care of the connectedness constraint. Résumé. Dans cette note nous présentons une méthode d’approximation du problème de Steiner par une famille de fonctionnelles de type Modica-Mortola, avec un term...

DNA sequences (~3 kb long) extending from the intergenic spacer 1 (IGS1) region to the 18S gene were obtained for isolates of Armillaria ostoyae, Armillaria calvescens, Armillaria gallica, and Armillaria sinapina. Additional investigation of 16 A. ostoyae, 11 Armillaria gemina, 21 A. calvescens, 18 A. gallica, and 15 A. sinapina isolates produced 117 sequences spanning the 3’ end of the IGS1 th...

Chez les sujets jeunes, la survenue d'un syndrome coronaire aigu (SCA) est souvent la première manifestation de la maladie coronaire. Les objectifs de notre travail étaient de caractériser les données coronarographiques, d'étudier la survie moyenne, et la qualité de vie chez les sujets jeunes caucasiens. C'est une étude rétrospective (2000-2007) descriptive et analytique qui incluaient 62 patie...

Nous exhibons une famille d’automates de McCulloch et Pitts de taille 2nk+2 qui est simulable par un réseau d’automates de Caianiello de taille 2n+2 et de taille mémoire k. Cette simulation nous permet de retrouver l’un des résultats de l’article suivant: [Cycles exponentiels des réseaux de Caianiello et compteurs en arithmétique redondante, Technique et Science Informatiques Vol. 19, pages 985...

First-year seedlings of shortleaf pine (Pinus echinatu Mill.), southern red oak (Quercus falcatu Michx.), and white oak (Quercus alha L.) were subjected to simulated prescribed burns during August (growing season) or January (dormant season) on an IJpper Coastal Plain site in southeastern Arkansas, U.S.A. Survival and growth of resprouting rootstocks were compared with control seedlings through...

Nous montrons que I’ensemble des codes cycliques etendus primitifs, d’une longueur don&e, invariants sous le groupe affine (codes affines-invariants), peut etre identifi6 a I’ensemble des antichaines d’un certain produit de chaines. Nous proposons ainsi une classification de ce corpus de codes dont I’inttret principal est qu’une antichaine donnCe permet d’obtenir de nombreuses propriCtCs sur le...

The two-parameter gamma model is widely used in reliability, environmental, medical and other areas of statistics. It has a two-dimensional sufficient statistic, and a two-dimensional parameter which can be taken to describe shape and mean. This makes it closely comparable to the normal model, but it differs substantially in that the exact distribution for the minimal sufficient statistic is no...
