Analysing spatial familiarity aims to measure how places included in the life-world and in the cognitive map are familiar. Based on the study of Gale, Golledge, Halperin & Couclelis (1990), this paper explores the spatial familiarity of the inhabitants of two municipalities at the fringe of Liege (Belgium): it questions the links between the cognitive dimensions (visual, nominal, localisation) and themselves and the behavioural dimension (passing). It seeks new relevant places for the population of these urban fringe as well as the favourable factors to a good familiarity of a place. Finally, it scrutinizes the influence of people's mobility – period of residence, commuting to work, modes of transport – on spatial familiarity. [less ▲]

The lightweight concrete with bio-based products knows an interesting development in the construction field, especially as thermal insulation panels for walls in buildings. Before identifying and quantifying the basic physical characteristics of concrete made from wood, miscanthus, hemp or bamboo (acoustic and thermal properties in particular), it is necessary to optimize the composition of the product. It is clear that the final product is not unique and a compromise has to be found between insulation and mechanical properties. The long term stability as well as the reinforcement may be obtained by means of a mineralization process of the natural product: a preparation with a lime and/or cement-based material is necessary to reinforce the cohesion of the bio-based product. Optical and SEM analysis helped to clearly understand the interactions between the bio-based fibrous material and the cementitious materials, the quality of the bond and their effects on the properties of the cement-based concrete products.

Meprin-α is a metalloprotease overexpressed in cancer cells, leading to the accumulation of this protease in a subset of colorectal tumors. The impact of increased meprin-α levels on tumor progression is not known. We investigated the effect of this protease on cell migration and angiogenesis in vitro and studied the expression of meprin-α mRNA, protein and proteolytic activity in primary tumors at progressive stages and in liver metastases of patients with colorectal cancer, as well as inhibitory activity towards meprin-α in sera of cancer patient as compared to healthy controls. We found that the hepatocyte growth factor (HGF)- induced migratory response of meprin-transfected epithelial cells was increased compared to wild-type cells in the presence of plasminogen, and that the angiogenic response in organ-cultured rat aortic explants was enhanced in the presence of exogenous human meprin-α. In patients, meprin-α mRNA was expressed in colonic adenomas, primary tumors UICC (International Union Against Cancer) stage I, II, III and IV, as well as in liver metastases. In contrast, the corresponding protein accumulated only in primary tumors and liver metastases, but not in adenomas. However, liver metastases lacked meprin-α activity despite increased expression of the corresponding protein, which correlated with inefficient zymogen activation. Sera from cancer patients exhibited reduced meprin-α inhibition compared to healthy controls. In conclusion, meprin-α activity is regulated differently in primary tumors and metastases, leading to high proteolytic activity in primary tumors and low activity in liver metastases. By virtue of its pro-migratory and pro-angiogenic activity, meprin-α may promote tumor progression in colorectal cancer. [less ▲]

due to their tracking experience in pursuing Polar Bears (Ursus maritimus), Inuit hunters could provide non-invasive estimates of Polar Bear characteristics from tracks, and Polar Bear monitoring programs could benefit from Inuit input. We determined i) inter-rater reliability of estimates of the sex, age, and size of Polar Bears, and estimates of the age of tracks made by a group of nine Inuit hunters who interpreted 78 tracks; ii) we made preliminary comparisons of sex and size estimates with conventional (scientific) estimates; iii) we catalogued the Polar Bear hunting experience and track interpretation techniques of nine Inuit hunters; and iv) we explored relationships between hunting experience and the ability to interpret tracks. The group of Inuit hunters made reliable and consistent estimates of Polar Bear sex, age, and size, as well as estimates of age of track (after data from one participant was excluded). Although our comparisons are based on small samples, our findings suggest that Inuit hunters may be accurate in estimating the sex of Polar Bears (74.42% agreement with genetic determinations) and the size of Polar Bears from their tracks. our data indicate shared tracking techniques used by hunters may explain high agreement in making specific estimates, while individual hunting experience and particular methods used to interpret tracks may lead to inter-rater reliability and accuracy in interpreting tracks.

In this paper, mitochondrial mutants of Chlamydomonas reinhardtii defective for respiratory complex I (NADH:ubiquinone oxidoreductase), complex III (ubiquinol cytochrome c oxidoreductase) and both complexes I and III were analyzed for H2 photoproduction. Several parameters were followed during the S-deficiency stage and the anaerobic stage leading to H2 photoproduction. At the early aerobic S-deficiency stage, starch and neutral lipids accumulated in all strains but their amount was significantly decreased in mutants compared to wild type. During the H2 photoproduction process, whereas starch content strongly decreased in all strains, neutral lipid amount remained nearly unchanged, suggesting that starch degraded by glycolysis is the preferential substrate for energy production during anaerobiosis. The mutants displayed a decrease in H2 photoproduction correlating to the number of active mitochondrial proton-pumping sites lost in the strains. Our results thus highlight the critical role of oxidative phosphorylation during the first (aerobic) stage of S-starvation when carbon resources are accumulated. [less ▲]

Peut-on substituer l'image au discours et conserver une démarche scientifique ? Dans ce livre, une équipe interdisciplinaire, réunissant des chercheurs belges et québécois, explore cette question à travers l'outil « carte mentale ». Rarement utilisé en science politique, cet instrument de collecte de l'information permet d'accéder à des données originales, spontanées et libres à propos d'une multitude d'objets, allant du cyberespace au fédéralisme, en passant par des politiques publiques et des sujets sensibles tels que les génocides. En mettant en évidence les différentes acceptions et les diverses formes de la carte mentale et en soulignant les forces mais également les limites de cet outil, l'objectif de cet ouvrage est d'identifier les potentialités que recouvre cet instrument de collecte de l'information pour la science politique et les sciences sociales en général.

Bone fracture healing is a complex process in which angiogenesis or the development of a blood vessel net work plays a crucial role. In this paper, a mathematicalmodel is presented that simulates the biological aspects of fracture healing including the formation of individual blood vessels. The model consists of partial differential equations, several of which describe the evolution in density of the most important cell types, growth factors, tissues and nutrients. The other equations determine the growth of blood vessels as a result of themovement of leading endothelial (tip) cells. Branching and anastomoses are accounted for in the model. The model is applied to a normal fracture healing case and subjected to a sensitivity analysis. The spatiotemporal evolution of soft tissues and bone, as well as the development of a blood vessel network are corroborated by comparison with experimental data. Moreover, this study shows that the proposed mathematical framework can be a useful tool in the research of impaired healing and the design of treatment strategies. [less ▲]

Pharmaceutical counterfeiting is a permanently growing problem. Control laboratories are constantly analysing counterfeit medicines. In industrialised countries, one of the main counterfeited class of medicines are erectile dysfunction drugs. This paper describes the development and validation of a fast method to detect and quantify the three authorised phosphodiesterase type 5 inhibitors and five analogues. The method is based on the use of a sub-2 microns polar-embedded column with a gradient using acetonitrile as organic modifier and 10 mM ammonium formate buffer (pH 3.5) as aqueous component of the mobile phase. The separation was achieved in less than 4.5 min. The method has also been compared to the registered HPLC method for the assay of Viagra® which was considered as the reference method. The method is also compatible with on-line coupling mass spectrometry and will significantly reduce analysis times and solvent consumption. [less ▲]

En Guatemala, para alcanzar los Objetivos de desarrollo del Milenio se implemen- tan Programas Conjuntos con el apoyo del Sistema de Naciones Unidas. Existen en la actualidad cinco Programas Conjuntos apoyando temas de seguridad alimen- taria, construcción de la paz, cambio climático, género y gobernabilidad económi- ca del agua. En el marco del programa conjunto: “Gobernabilidad económica en agua y sanea- miento” se decidió realizar un estudio que permitiera conocer la gobernabilidad en el sector a partir de hacer un inventario de las agrupaciones usuarias de agua con fines agrícolas y conocer algunas de sus características, este estudio contó con la asesoría técnica de la Organización de las Naciones Unidas para la Agricultura y la Alimentación –FAO– y el apoyo en campo de las comunidades asociadas por el agua y el medio ambiente de la cuenca del río Naranjo –CADISNA– en coordina- ción con el Ministerio de Agricultura Ganadería y Alimentación –MAGA– y go- biernos locales. El estudio se realizó en 8 municipios, 3 del departamento de Quetzaltenango y 5 de San Marcos, se identificaron 126 grupos de riego, de ellos, 73 pudieron ser carac- terizados. Se conoció que el 92% de los 73 grupos tiene una junta directiva que vela por el funcionamiento del sistema y la producción se ve diversificada en al menos 14 diferentes hortalizas siendo la principal el cultivo de la Papa. Sin embar- go sólo el 45% paga una tarifa a su grupo y el 60% de los usuarios necesita crédito para poder producir, haciendo uso de al menos 271.99 Lts/seg de agua para fines agrícolas. [less ▲]
