Inutile de le présenter : Google est le moteur de recherche le plus connu et le plus utilisé au monde. Mais comment les concepteurs de Google font-ils pour classer les milliers de pages se rapportant à un mot-clé donné, de façon telle que les pages les plus représentatives occupent toujours les premières positions du classement ? Ce tour de force repose sur de véritables résultats mathématiques combinant théorie des graphes et algèbre linéaire. [less ▲]

L’étude présentée propose d’examiner, parmi 184 travailleurs luxembourgeois, le lien entre le temps de travail, y compris les horaires atypiques, l’interaction vie privée-vie professionnelle et le bien-être au travail. Les résultats principaux relèvent un effet significatif (négatif) du travail de week-end, du travail de nuit et des horaires compressés sur l’influence négative travail-famille. Un effet significatif (négatif) de l’horaire compressé sur l’influence positive travail-famille est aussi mis en évidence. Enfin, le temps partiel serait lié à un niveau de stress plus faible et une influence négative du travail sur la famille plus faible. Cette dernière jouerait par ailleurs un rôle de modérateur partiel entre le temps de travail et le stress négatif. [less ▲]

This research is part of an integrated paleoecological project which aims at coupling reconstructions of past vegetation and water-quality changes with climate variability. Crater-lakes from East Africa are favourable to the conservation of proxy indicators such as plant macrofossils used to reconstruct the lake ecosystem. The study of modern macrophytic communities in relationship with present environmental parameters was the first step of this research. Eventually, it will allow us to select species with high proxy-indicator value. Phytosociologic and environmental data were collected in 18 crater-lakes in South-western Uganda. In each relevé, species abundance and habitat conditions were described. Environmental parameters were used to develop a lake typology. A cluster analysis identified 6 aquatic and semi-aquatic communities and the indicator species were highlighted. The CA ordination emphasized the importance of geography, physico-chemistry and trophic level in the community structure. Temperature, pH, sediment type, depth and slope were the most correlated parameters to floristic variation in the CCA ordination. These preliminary results give some trends about the ecology of macrophytes communities. A complete dataset and the study of species ecological range will allow us to go further in the ecological significations of macrofossils. [less ▲]

Aims.For Seyfert galaxies, the AGN unification model provides a simple and well-established explanation of the type 1/type 2 dichotomy through orientation-based effects. The generalization of this unification model to the higher luminosity AGNs that quasars are remains a key question. The recent detection of type 2 radio-quiet quasars seems to support such an extension. We propose a further test of this scenario. Methods: On the basis of a compilation of quasar host-galaxy position angles consisting of previously published data and of new measurements performed using HST Archive images, we investigate the possible existence of a correlation between the linear polarization position angle and the host-galaxy/extended emission position angle of quasars. Results: We find that the orientation of the rest-frame UV/blue extended emission is correlated to the direction of the quasar polarization. For type 1 quasars, the polarization is aligned with the extended UV/blue emission, while these two quantities are perpendicular in type 2 objects. This result is independent of the quasar radio loudness. We interpret this (anti-)alignment effect in terms of scattering in a two-component polar+equatorial model that applies to both type 1 and type 2 objects. Moreover, the orientation of the polarization -and then of the UV/blue scattered light- does not appear correlated to the major axis of the stellar component of the host-galaxy measured from near-IR images.

The urban infrastructure, particularly water supply and drainage systems, have deteriorated severely in the past two decades in Phnom Penh, the capital city and the economic center of Cambodia. Water pollution caused by untreated wastewater is one of the serious problems that confront most developing countries (Kwai et al.1991). In Phnom Penh City, all kinds of wastewater are discharged to rivers, lakes and wetlands throughout the city without proper treatment causing serious surface water pollution. Water testing is an essential factor to control water pollution. However, water quality data and water quality testing systems are still poorly developed in Cambodia due to lack of facilities and technical expertise. Therefore, there is no information available on sewage water quality in Phnom Penh City. That’s why the work is aimed at collating basic information about the situation of water supply, waste water system and solid waste. The present information will provide the basis for targeting further field research. This is included the overview of sources and activities that may lead to pollution, with an appreciation of type of water pollutants involved, their magnitude and movement. Types of waste and effluent disposal including sanitation, liquid and solid waste management systems are described. After reviewing all the available, we found that the distribution of water has been well organized by the Phnom Penh Water Supply Authority while the managements of the wastewater, storm water and solid waste are poor due to the rapid urbanisation and industrialisation.
