New biogeographical, ecological and phenological data on Rhacocleis poneli Harz & Voisin, 1987 (Orthoptera, Decticinae). Recent data widens considerably the geographical distribution of Rhacocleis ...poneli, which remains however endemic to the département du Var (France). This katydid was previously regarded as strictly dependent on coastal riverine forests ; in fact this species proved to be much less stenotopic since the new localities scattered throughout the département show a wide range of ecological conditions. Finally, its activity period persists relatively late in the year since singing specimens displaying a reproductive behaviour where observed until early December.
Des observations récentes élargissent considérablement la répartition géographique de Rhacocleis poneli Harz & Voisin, 1987 (Orthoptera, Decticinae), qui reste pour l'instant endémique du département du Var (France). Considérée initialement comme propre aux ripisylves côtières, cette espèce s'avère en fait bien moins sténotope que prévu puisque des stations très variées sur le plan écologique ont été mises en évidence en divers points du département. Enfin, sa période d'activité se prolonge relativement tard dans l'année puisque des individus chanteurs présentant un comportement reproductif ont été observés jusque dans les premiers jours de décembre.

This paper represents a contribution toward finding a complete set of electron collision cross sections for the methane molecule by revising all of the collision cross sections and adding the partial ...collision cross sections data relating to dissociation by electron impact. For the latter, there are no available measurements data for each channel of dissociation and no validated recommended data for use in the modeling, although these data are very important in order to determine different species in a methane plasma. The rate coefficients of the partial dissociative collisions into neutrals and the partial ionization collisions are also calculated, and when fitted, these can be used as input for fluid models. This paper is concluded by the validation of our set of data through a comparison between the transport coefficients calculated by using our data and the measurements of the transport coefficients that already exist in the literature.
In the Covid-19 outbreak, the teacher should have the performance to be able to deal with the problems, opportunities, and challenges they face during distance learning. A phenomenological ...qualitative research method was used in this research to explore the identity of the Arabic language teacher at MIN 04 West Kotawaringin represented by their performance in the daily learning process. The data of this study were obtained from the analysis of interviews, observations and documentation. Interviews were conducted with two Arabic language teachers at MIN 04, students and the principal as the informants. The results showed that the teacher's performance could be seen from; the responsibilities in carrying out the task as a representation of their identity as an Arabic teacher who deal the problems and conditions about the learning facilities, enjoyable technique of teaching and learning, adapt to the use of digital-based media, take different learning resources, and take the initiative to use the most accessible and affordable methods. It was in line with the theory of teacher identity by Anne Graham and Renata Phelps that the teacher should be able to overcome the obstacles faced by both problems from students and infrastructure. This research could be a reference so that teachers can represent their performance, not only as a responsibility but also as a teacher's identity. Furthermore, this research hopefully can examine quantitatively regarding the identity of Arabic teacher in Central Kalimantan.
Mediterranean ecosystems are subject to the influence of particular climatic conditions characterized by scarcity or irregular rainfall and long dry summer periods. These climatic restrictions ...generally disturb the vegetation. In order to overcome these problems. The use of pioneer tree species, adapted to climatic hazards, remains the most recommended solution. The carob tree (C.siliqua) is an agro-sylvo-pastoral species with enormous socio-economic and ecological interests. This Mediterranean tree is favourably established in semi-arid and arid areas. For the success of reforestation projects, the management and preservation of this species requires prior assessment and characterization of their variability. This approach is based on multidisciplinary studies involving the analysis of the diversity of agro-morphological, adaptive traits. In this context, the present study aims to explore, using agro-morpho-metric markers of the carob tree in central and north-western Algeria. We use the pods and leaves to identify, label or characterize the different collections or germplasm of the carob tree in the world. This study was carried out on the variability of nine morpho-metric traits related to fruits (pods) and leaves through a comparative study at the level of provenances (Larabaa, BordjBounaama, Aflou, Remchi and Ain Sefra). Carob plants from three contrasting ecotypes of Ceratoniasiliqua (Remchi ecotype from the sub-humid stage, Tissemsilt and BordjBounaama ecotype from the semi-arid stage and Ain Sefra and Aflou ecotype from the arid stage) were subjected to a thorough biometric study of the leaves and pods collected after a field survey in June-July 2013. The results showed the highest mean values for the majority of the traits studied, thus indicating the importance of the provenance factor. Based on the analyses of variance and their decomposition, and depending on the biometric traits studied, the carob resource management strategy can be chosen either for the pod factor (pod weight, pod length, number of seeds per pod and number of infested seeds per pod) or the leaf factor (petiole length and leaf area). In the case of our collections, the longest size was recorded in the Bordj Bounaama population (16.66 cm ± 2.36) and Remchi (16.10 cm ± 2.78) and the smallest in the Aflou population (9.40 cm ± 1, 27). Indeed, a positive correlation between the measured parameters (length, width, thickness and weight of the pod) was observed. Differences between ecotypes were observed for all morphological traits studied.
The electrical discharge plasma in methane is used in many fields of technology and the knowledge of the electron impact cross sections with the molecule of this gas is necessary for the modeling, ...which represents a good tool for understanding this phenomenon. The main object of this work is a finding the important electron impact cross sections with the methane molecule through the reviewing the theoretical and measured data found in the literature
To develop the modeling of electrical discharges in a gaseous medium, it must to know a numbers of basic data such as: the electron collision cross sections for particle modeling or the electron ...swarm parameters in the case of the fluid modeling. The knowledge of all the electron swarm parameters as a function of the reduced electric field is indispensable for the fluid models based on the first and the second moment of the electron energy distribution function. The objective of this work is to calculate the mobility, the characteristic energy, and the ionization coefficient in the case of the mixtures Ar/H2 and Kr/H2. The results obtained will be compared with measurements already made by different authors.
Introduction La présentation clinique du pied diabétique est très variable, d’évolution imprévisible, dépendante des facteurs favorisants, et des complications associées. Matériels et méthodes Nous ...décrivons le cas d’un patient hospitalisé pour pied diabétique dont la lésion était atypique. Cas clinique Mr A. R âgé de 81 ans, diabétique type 2 connu depuis 31 ans sous insulinothérapie, hypertendu bien équilibré sous mono thérapie, admis pour ulcération sur infectée de la face latéro externe du pied gauche. Le début d’apparition remontait à un an après l’application par automédication d’un coricide pour hyper kératose plantaire. Le patient était en bon état général, un BMI à 27 kg/m2 et présentait une neuropathie périphérique bilatérale en chaussettes. La lésion était une perte de substance superficielle de 2 × 2 cm, dure en son milieu, avec nécrose superficielle, il n’y avait pas à la radiographie du pied une ostéolyse, le doppler artériel des membres inférieurs révélait une AOMI ; le patient a reçu une antibiothérapie à large spectre et des soins locaux qu’il a continué à recevoir après sa sortie pendant 4 semaines. Un hématome est apparu 20 jours après au niveau de la lésion, une thrombopénie modérée a été retrouvé, l’hématologue a indiqué une surveillance. L’évolution était marquée par l’apparition d’une nécrose sèche sur le pourtour de la lésion avec hyper bourgeonnement, le patient recevait toujours une antibiothérapie et des soins locaux, la nécrose avait disparu, il ne persistait que l’hyper bourgeonnement. À noter que le patient n’a reçu aucun facteur de croissance en application locale. Devant cette excroissance tissulaire à masse bourgeonnante polylobée qui saignait au contact et qui résistait aux différents traitements, une biopsie a été faite révélant un mélanome malin nodulaire ! le patient a été confié aux dermatologues pour prise en charge. Conclusion Les lésions du pied chez le patient diabétique peuvent être trompeuses nécessitant une vigilance au moment du diagnostic et tout le long du suivi.
