Ethnic (racial) differences exist for a series of physiological skin characteristics. Colour is responsible for typology and resistance to ultraviolet irradiations. Other differences have also been reported for the transepidermal water loss, the size and cohesion of corneocytes, the vascular reactiviy, the biomechanical properties, the pH, the lipidic content, the superficial microflora and the structure of mast cell granules.

Some cutaneous functions of importance are governed by periodical variations according to the nycthemeral timing. Similarly to other organs, the skin is under the influence of a coherent organisation of circadian and nythemeral rhythms modulating various biological cycles which usually display a wide amplitude. The cutaneous biorhythms in humans suggest that during daylight the skin boosts diverse protective functions with regard to environmental threats. In the evening and at night, the skin increases its renewal and diverse metabolic processes. Biorhythms in the skin which are in line with the organism's needs, merit to be recognized. Chronophysiology, chronopathology and clinical chronopharmacology may help reach optimal therapeutic decisions. [less ▲]

Dermatopathology is a tool using the microscopic examination for diagnosing cutaneous diseases. The frontiers of its field of interest were extended by exploring the physiopathology of skin functional properties. An example is provided by the evaluation of alterations of skin suppleness in various connective tissue disorders. This approach takes profit from both conventional histology and histochemistry. Immunohistology targeting dermal dendrocytes reveals their various shapes reflecting the modifications in tensegrity under the control of mechanobiology. The latter property is an indicator of the evolution and severity of the connective tissue changes. Electron microscopy is also very instructive in this field. The in vivo examination by dermoscopy highlights a similar mechanism involving the melanocytes. From an engineering point of view, the skin and subcutaneous tissue represent an integrated load-transmitting structure. It is subjected to intrinsic and environmental influences. Some models were offered to explain how skin withstands and transmits loads through deforming appropriately or abnormally according to disorders of the connective tissue structure. We report a brief review of the principles of interpretation of the measurements of the skin biomechanical properties, and the histological presentations of mechanobiology. The applications of such investigations are summarized in the Ehlers-Danlos syndrome, inguinal hernias, gravitational syndrome, diabetes, scleroderma, hemodialysed patients, in case of growth hormone administration and during climacteric.

As part of the overhauling of the building energy efficiency regulations (following European directive 2002/91/CE), the Wallonia and Brussels-Capital Region commissioned the LUCID to develop an optional 3D graphic encoding module to be integrated with the core energy efficiency computation engine developed by Altran Europe. Our contribution consisted mostly in analyzing the target users’ needs and representations (ergonomics, UI, interactions) and implementing a bespoke 3D CAD modeler dedicated to thermal models of buildings taking into account the various geometrical and relational constraints specific to thermal modeling.

Tanganyika Lake is frequented by many fish-eating birds, especially kingfishers. Our research has focused in particular on Ceryle rudis Linné, 1758, pied kingfisher. This study, conducted over a period of two months, from June 21 to July 19 and from August 19 to September 16, 2002, aims to analyze the fishery of pied kingfisher, considering fishing time during the day, before and afternoon. This bird was fishing from a perch or a hovering position. This regularly observed behavior allows the bird to fish in the pelagic water, which is uncommon in other species of kingfishers. This part distinguishes direct dives carried out from a perch and dives performed after a hovering position. Results show that, on a total of 583 dives, 324 or 55,5% were dives from perches while the rest were made from a hovering position. We found that Ceryle rudis is very active in fishing until midday and it is less so in the afternoon. The average number of fish eaten per day per bird was 9,3. [less ▲]

The microstructure and the rheological properties of lemon-pectin mixtures were studied and compared to those of pure lemon (high methoxyl: HM) and date (low methoxyl: LM) pectins. Rheological properties were carried out in the presence of 30%, 45% and 60% sucrose, and increasing calcium concentrations (0-0.1%). The presence of date with lemon pectin led to a gel formation at 45% sucrose and in the presence of calcium, which was not the case for lemon pectin alone under the same conditions. It is suggested that lemon and date pectins interacted, leading to gel formations at different gelling temperatures, which were strongly dependant on degree of methylation. These results were confirmed by scanning electron microscopy, which revealed inhomogeneous gels where dense aggregated network and loose, open network areas were present. Addition of calcium to pectin mixture gels led to stronger and faster gel formation. [less ▲]
