Since the beginning of research on the éperon barré of Pont-de-Bonne (Modave, Belgium), we have recovered artefacts attributed to the Middle Neolithic. More recently, during excavation of the entrance system of the fortification, a pot hole and a waste accumulation zone have been analysed. These structures contained abundant archaeological material (ceramic sherd, lithic and bone artefact and fauna). Three radiometric dates have been obtained. The ceramic assemblage is typical of the Belgian Michelsberg and a decorated vase shows Bischheim affinities. [less ▲]

Introduction: Miconazole (MCZ) is a time-honored antifungal of the imidazole class. MCZ exerts a multipronged effect on fungi. It inhibits the cytochrome P450 complex, including the 14alpha-demethylase enzyme required for ergosterol biosynthesis, in fungal cell membranes. In addition, intracellular accumulation of toxic methylated sterols occurs and the synthesis of triglycerides and phospholipids is altered. Disturbances in oxidative and peroxidative enzyme activities lead to an intracellular toxic concentration of hydrogen peroxide. As a result, intracellular organelle destruction then leads to cell necrosis. Farnesol synthesis stimulated in Candida spp. prevents the yeast-to-mycelium formation. MCZ is further active against Gram-positive bacteria. Areas covered: This review aims at revisiting the MCZ antifungal activity in dermatomycoses. Expert opinion: MCZ's wide spectrum of activity appears noteworthy. The full pharmacological profile of MCZ indicates its fungistatic profile through its effect on ergosterol biosynthesis. In addition, it exhibits a fungicidal effect against a number of fungal species, due to hydrogen peroxide accumulation. MCZ is characterized by high safety, efficacy and versatility, and a unique, multifaceted nature of activity in the treatment of dermatomycoses. [less ▲]

This paper presents the experimental and numerical tests made on the Titanium based alloy Ti6A14V to identify its yield locus and the hardening behaviour. A bi-axial experimental equipment has been used to perform cyclic shear tests, simple shear tests and successive simple shear tests and plane-strain tests. Coupled with classical tensile tests, these tests enable to identify the yield locus and the hardening model. Teodosiu and Hu’s hardening law and isotropic Swift type hardening and kinematic Armstrong Frederick hardening models have been investigated. [less ▲]

Nowadays, tillage simplification is an increasing practice. Many advantages are cited in the literature, such as energy saving, soil conservation etc. Agricultural management practices influence soil structure, but consequent changes in soil hydrodynamic behaviour at the field scale are still not well understood. Many studies focus only on macroscopic measurements which do not provide mechanistic explanations. Moreover, research shows divergent conclusions over structure modification. The aim of this work is to fill this gap by quantifying soil structure modification depending on tillage intensity through both macroscopic and microscopic measurements, the latter improving our comprehension of the fundamental mechanisms involved.

ABSTRACT Financing the rural economy has always been one of the main preoccupations of the Cameroonian economy which is 80% agricultural. The 1980-1990 decade has been marked in Cameroon by the drastic fall in the kilogram price of coffee and cocoa; state disengagement from the sector of activities in the rural world and the implementation of the structural adjustment policies. In the context of economic and financial crisis, promoters of microfinance establishments invented new development strategies from the base. These new strategies were based on inclusive co-production, to tackle the financial exclusion and the social security of low income rural populations. Among the microfinance establishments intervening in financing in rural areas, figures the network of MC² (Community Growth Assistance or Village Community Bank), which is a group of agencies whose principal objective is to restore hope to the poor. The research question that has guided this work to progress: are MC² agencies proposing a different approach to financing economic and social projects in the rural world of Cameroon? To answer this question, we set as objective to analyse changes in the social-economic status of promoters of projects in Village Community Bank (MC²). The general hypothesis to be verified is as follows: MC² agencies propose a different approach to financing economic and social projects in the rural world Cameroon. This Doctorate/Ph.D work is organised in three parts: the first part presents the network of MC² agencies in Cameroon. The second one treats the initiatives of MC² in Cameroon. The third part is interested at the outcomes of the initiatives of MC² in Cameroon. The methodology adopted for the realisation of these three parts is based on the exploitation of data from documented sources from libraries, from the MC² network and from seminar and colloquium reports. To complete these data, direct field observations and field, surveys using questionnaires and semi-guided interviews were conducted with resource persons of MC² agencies, the Camccul, Adeac, Nowefor network and administrative sources. According to surveys results carried out from 1992 to 2008, all the 79 agencies and rural development funds MC² distributed in the 10 administrative regions of Cameroon have mobilised funds of about 20 billions CFA francs of savings, representing 18.18% of the total funds collected by EMF in Cameroon. During the same period, they collected and distributed 30 billions CFA francs of loans, representing 22.5% in total loans of the EMF of the country. This sum represented 22.53% of EMF credit of the country. The credits thus collected were directed towards the financing of 29 920 economic and social projects (individual and community). More than 600 000 customers of MC², representing 11.53% of the total EMF customers with 93 410 individual members (82 280 men and women) and 11 130 groups of 50 people on average as against 5 200 000 customers of all the EMF of Cameroon were directly affected and 1000 000 persons indirectly, by a varied gamme of financial and non financial products and services. These banking products comprise of: loans, savings, transfer of funds, training and taking care of the members, advice on householding. This research work has demonstrated that from of the 420 customers surveyed, whose economic projects benefited from MC² financing, 300 of them representing 71.41% witnessed an annual increase in their incomes of at least 150 000 CFA francs. In like manner, 35.71% of agricultural and commercial project promoters, 11% of cattle, pigs, sheep, goats and poultry rearing projects, 9.52% promoters of fish rearing projects and 7.14% of promoters of crafts projects became autonomous after reimbursing at 100% the loans to their MC² agencies. The distribution of economic and social projects has been unequal across all the regions of Cameroon. This unequal distribution concerned the different types of projects financed as well as the accumulated amount given out. For example, the MC² agencies of West Cameroon financed in 2008, some 5 300 individual economic projects to the tune of 3 500 000 000 CFA francs against 250 individual economic projects financed by the MC² of South Cameroon to the tune of 20 000 000 CFA francs. The immediate gains of these projects permitted promoters to ameliorate their well being as concerns: access to basic necessities, basic education; access to health care; the construction and the amelioration of dwellings. The different approaches of MC² in the sustainable financing of economic project in the villages of Cameroon, therefore, concern: the availability of credit, provision of consumption loans, availability of investment loans. It also concerns support to the organisation of mini agricultural shows in MC² villages, support to projects and programs of women independence, the democratisation of access to credit using authentic collateral security and the follow up - evaluation of conception, implementation and profit stages of customers projects, by the managers and qualified agronomists. The diversity of non financial services and the financing strategies of social projects have permitted: to creat four solidarity health centres, five multi-media centres, four stores, one school farm training centre, support to the training of householding councellors and the vulgarisation of agricultural innovation. Changes that have resulted from these different approach and strategies put in place by these agencies in MC² villages of Cameroon are: increase in purchasing power has given opportunity to average, big customers and promoters of economic projects to change their social status and to build new social identities. In like manner, increase in the revenue of small customers, promoters of small economic projects has permitted the later to ameliorate their well being. This Doctorate/Ph.D thesis brings out the possibility to reduce the negative effects of poverty on the rural population, on the condition that the microfinance structure associate to their traditional services of micro credit and savings, innovating and complementary micro insurance and solidarity health association. Defeating poverty in rural areas rests on integrating the 3M model to the process of community development, where the formula VP= 3M. The main objective of this study has been achieved. Its general hypothesis confirmed since the MC² agencies have succeeded in proposing in 79 villages a new approach of rural financing based on the solidarity chain in intergrating the rich cultural heritage to financial innovation. Key words: microfinance, financial exclusion, MC² network, inclusive co- production, 3M model. [less ▲]

Stiction is a major failure mode in micro-electromechanical systems. In previous works, a statistical rough surfaces interaction model, for which only elastic adhesive contact has been considered, was developed for multiscale analyzes. However, during the impact between rough surfaces, plastic deformations of asperities cannot always be neglected. In the present work, the adhesion between rough surfaces is studied considering the elasto-plastic deformations of the asperities, and a model predicting the resulting micro adhesive-contact forces is derived. For illustration purpose, an electrostatic-structural analysis is performed on a micro-switch. To determine the degree of plasticity involved, the impact energy of the movable electrode at pull-in is estimated. Thus the maximal adhesive force evolution during cyclic loading is predicted using the developed model. [less ▲]

Concurrently to research conducted on ordinary Portland cement (PC), new types of binders were developed during the last decades. These are formed by alkali-activation of metakaolin or ground-granulated blast furnace slag (GGBFS) and are named, respectively, geopolymers (GP) or alkali-activated slag (AAS). Four different cementitious materials were synthesised: PC, AAS, GP, and a mix GP-AAS and fully compared about their compositions and (micro)-structures. X-ray diffraction has revealed the presence of semi-crystalline C-S-H gel binding phase in PC while AAS, GP and GP-AAS are nearly amorphous. Progressive structural changes have been observed between the different samples by means of infrared spectroscopy, Si-29 and At-27 magic-angle-spinning nuclear magnetic resonance spectroscopy: there is a polymerisation extent of the (alumino)-silicate framework from PC [SiQ(1) and SiQ(2) units] to AAS [SiQ(2) and SiQ(2)(1Al) units] and finally to GP [SiQ(4)(2Al) and SiQ(4)(3Al) units]. Scanning electron microscopy has shown that GP is a homogeneous matrix while the other materials are composites containing GGBFS grains surrounded by a binding matrix. Energy dispersive X-ray EDX analyses (line scans) have shown the absence of formation of any specific phase at the matrix-grains interfaces. (c) 2006 Elsevier Ltd. All rights reserved. [less ▲]

Hydrologic similarities between catchments can be of use in the context of overland flood and mud flow hazards management. In Wallonia, upstream micro-catchments were mapped for each runoff concentration axis. The outlets of these catchments are considered at the point where water reaches the permanent river stream. No less than 145 547 micro catchments were mapped in Wallonia (16900 km²). Their area varies between 1 and 1233 ha (mean area: 7.8 ha). A data base was built up to synthesize their major characteristics like e.g. area, shape and mean slope. No clear classification appeared. At this stage, it became obvious that the major components of these catchments had to be handled simultaneously from a hydrological point of view in order to produce a clear classification. The main hydrologic significant data are available in Wallonia: the digital soil map at 1/20 000 scale, the DTM (raster file of 10 meters resolution), digital land use at 1/10 000 scale and spatial statistics for rain (IDF curves for each commune). A hydrologic model was developed using the python programming language in the ArcGis 9.3 environment. This model is based on the NRCS – USDA method. Rain abstraction is calculated on the basis of a CN (curve number) which integrates the soil type, the land use and the slope. Water transfer is computed using a convolution based on triangular unit hydrogrammes. This calculation includes the concentration time which integrates the catchment morphology (shape and slope) and the land use (roughness). The MUSLE equation is also computed in order to handle the sediment problem. The results consist in a full project hydrograph, peak flow value, flood water volume and sediment quantification in response to a project rainfall. The CN and MUSLE semi-empirical methods are validated at larger scale in Wallonia but have still to demonstrate their efficiency at the micro-catchment scale. Nevertheless, the aforementioned variables can be considered as integration factors of the whole hydrological context of the micro-catchments. It allows us to build advice on overland flow and mud flow mitigation at watershed scale. This approach can also be of help to compare ungauged micro-catchments between each other and possibly transpose the soil conservation practices from a site to another. [less ▲]

Perfusion bioreactors are known to exert shear stresses on cultured cells, leading to cell differentiation and enhanced extracellular matrix deposition on scaffolds. The influence of the scaffold's porous microstructure is investigated for a polycaprolactone (PCL) scaffold with a regular microarchitecture and a silk fibroin (SF) scaffold with an irregular network of interconnected pores. Their complex 3D geometries are imaged by micro-computed tomography and used in direct pore-level simulations of the entire scaffold-bioreactor system to numerically solve the governing mass and momentum conservation equations for fluid flow through porous media. The velocity field and wall shear stress distribution are determined for both scaffolds. The PCL scaffold exhibited an asymmetric distribution with peak and plateau, while the SF scaffold exhibited a homogenous distribution and conditioned the flow more efficiently than the PCL scaffold. The methodology guides the design and optimization of the scaffold geometry. [less ▲]
