Ce travail se propose d’analyser les phénomènes du séchage convectif d’un milieu poreux non saturé. Le modèle de calcul considère le couplage des équations de la couche limite et celles qui décrivent le transfert de chaleur et de masse dans un milieu poreux, ayant les caractéristiques du béton renforcé avec des coupeaux de bois. La simulation effectuée montre l’effet de certains paramètres pertinents du matériau comme la température initiale et l’humidité initiale, sur le processus du séchage [less ▲]

Various measurements were introduced at the European level following the awakening of the degradation of the agro-ecosystems and the decline of the species which were dependant, of which agri-environment schemes. This work studies one of these schemes setting up in Walloon Region: the sown wildflower strips. This work has been integrated in a follow-up of the sown wildflower strips organized by the Laboratory of ecology of FUSAGx and aCrea-ULg since 2007. A ground field in 2009 has allowed to collect data necessary to the follow-up which is focused on two taxons indicating with the success of the strips: flora and diurnal butterflies. Firstly, this work has set up and has described several indicators in order to evaluate the success of the sown wildflower strips. Secondly, this work has studied the influence of internal (characteristics of the site) and external factors to the strips (landscape context) on the composition and the evolution of the communities. For the study of the butterflies, the floristic characteristics of the strips have been also taken into account as elements of the habitat. It comes out from this work that the success of the strips is not systematic and that certain descriptive variables of the landscape seem to influence mainly the communities of butterflies. [less ▲]

Several studies have been done on the agency relationship in the social economy (Spear, R., 2004; Huybrechts, et al, 2013.), but few studies focused on the chain agency relationship (Jegers,M. et al.,2012). Recently, Manirambona, C.(2013) showed that a chain agency relationship has materialized in Africa through the financing circuit of the actors in relation: foreign donors-international NGOs-local NGOs-endogenous groups-beneficiaries. By essence, an agency relationship exists when the mandate delegates to the mandatory a portion of his authority (Jensen & Meckling, W.H.,1976). This problem happens whenever there is the presence of elements that affect the basic assumptions of the agency relationship such as opportunism, asymmetric information (Nyssen, M.,1998). Among these ones, there are elements of context, which result from the distance. The distance has attracted more interest in the literature on the company internationalization by approaching through the psychic distance concepts (Johanson et Vahlne,1977). The basic principle of most of the researches is that increasing the distance increases uncertainty and a potential risk of information asymmetry between partners in relation (Hutzschenreuter et al., 2014). Given this impressive literature addressing the concept of psychic distance leads to a high complexity of information asymmetry strengthening the agency problem in international trade, it is striking that we lack a literature of psychic distance effect on the agency relationship in social economy, even less when the latter is in Chain. So, we ask then the question of how the psychic distance influences the agency relationship between different levels of actors in relation in the NGO world. This study proposes a combination of differentiated theories between economic, socio-cultural theories and agency theory, thus an empirical examination through a case study of the factors influence of the psychic distance components (cultural, governance and economic distances) on the agency relationship.

Through a wide review of the litterature (330 references), the authors have tried to describe the determinant or predisposing effects of factors usually involved in the reproduction problems in beef or dairy cattle. These factors have been qualified as individual or herd factors. The first ones involve the animal itself like age, genetic, milk production level, dystocia, twinning, perinatal mortality, placental retentio, milk fever, uterine involution, metritis, post-partum ovarian activity. The second ones concern the environnement of the animal i.e. first insemination policy, oestrus detection, insemination time and technic, nutrition, season, stabulation, herd size or management capacity of the farmer. The authors conclude to the multifactorial etiology of the reproduction pathologies. It also appears necessary to develop data collection systems like herd health management programs. Such systems should be able to offer to the practitionner the opportunity to be involved more efficiently in the economic health of the herd using epidemiological tools to study the different implied factors.

L'actinomycétine (1*), filtrat de culture bactériolytique de certains Streptomyces, provoque la dissolution des bactéries tuées d'une part de certains microorganismes gram-positifs vivants d'autre part (2*). Ces deux activités sont attribuables, au moins en partie, à des agents distincts (3*, 4*, 5*, 6*), que nous pouvons désigner commodément sous les noms respectifs de : principe colilytique et principe staphylolytique. Nous montrons, dans cette note, que la présence de cations bivalents, dans le milieu de culture où l'actinomycétine est élaborée, modifie le rendement en principes lytiques et la cinétique de leur activité.

A sample of 150 jaws of hinds was collected from 1982 to 1984 in two different areas (Hautes Fagnes and Ardenne) where two different methods of hunting are applied. The age of the animals was determined by using tooth wear annual layers. Life tables showed that there are no high differences in the structure of the two populations according to the kind of hunting. [less ▲]
