ThermocinétiqueIndex. décimale : 668.4 Plastiques, vinyles Résumé : In mould curing process or composite functionalization is concerned by power exchange limitations and often requires stretchable fatigue withstanding heating circuits, because of the repeated heat cycles dilatation constraints. Note de contenu : - Inserting functional layers
- The three principal constraints : fatigue strength - dielectric constraints - heat exchange
- Specific case of carbon or conductive composites
- Micromesh for safety and to regulate ther thermal gradient

Traction (mécanique)Index. décimale : 668.5 Parfums et cosmétiques Résumé : The prolonged use of heat styling devices may lead to cumulative effects on the hair fibre. These involve various physical and chemical changes of hair cuticle and cortex structure that seem significantly linked to a gradual protein thermal denaturation after exposure to high temperatures. The worsening of hair sensory attributesland hair breakage increase caused by cuticle and cortex layers degradation, are amongst the long-term damages of heat hairstyling : The aim of the present study was to evaluate the potential use of two Kelisema's protein hydrolysates derived from sesame seeds (Kelipro Sesame, INCI : Hydrolyzed Sesame Protein) and hemp seeds (Kelihemp, INCI : Hydrolyzed Cannabis Sativa Seed Extract) as hair heat protectants. Simulating a customer hair care practice, virgin hair tresses were pre-treated with protein hydrolysates aqueous solutions and subjected to repetitive thermal stress cycles using a straightening iron. Single-fibre tensile testing was performed to assess hair damage ; dry-state hair break stress and hair diameter change were evaluated. Note de contenu : - OBJECTIVE :
- MATERIALS AND METHODS : Protein hydrolysates and test solutions - Hair samples - Thermal treatment of hair - Hair strength evaluation

Traîtements de surfaceIndex. décimale : 667.9 Revêtements et enduits Résumé : The authors describe the many interrelated elements that must be simultaneously considered to achieve a successful installation of flooring over concrete. Examination of different options is necessary to ensure a balance between a satisfied owner, a profitable installation and something everyone involved can be proud of producing.

- Pre-project determinations
- Applications constraints : Environmental conditions - Application method
- Specifications and regulations
- Material selection

- Fig. 2 : Heavy-duty vehicles such as front-end loaders introduce grinding and impact service as they routinely drop their bucket and scrape the edge along a floor that may have broken glass on its surface
- Fig. 3 : The chemical composition, concentration and temperature of what comes into contact with the flooring are primary considerations as is the duration of contact such as incidental spills versus continuous contact
