“…The negative r was because of our infrared measurements for A were suggestive that the glove maker increased A for the thinner gloves to try to compensate for decreasing thickness (Table ) and so is an artifact of glove design. The negative r is opposite to that expected since data in the literature support a direct linear relationship, that is, as A increases so too should SBT, other variables being constant but the thickness is not constant here. − This indicates that one-on-one linear regression results are not necessarily cause and effect if interactions are occurring that may be better described through multivariate analysis.…”

The current technique to assess glove resistance to chemicals for worker protection relies on challenging a flat, 2.54 cm diameter glove piece at or near room temperature. This does not simulate a donned whole glove near the skin temperature subjected to work activity forces. Four different types of disposable nonpowdered unlined/unsupported nitrile gloves in triplicate were measured for thickness, porosity, and for the acrylonitrile content (A) of the challenge and collection sides. Limonene permeation at 35 °C through a whole glove on a clenching and nonclenching dextrous robot hand and with the standard ASTM F739 technique were facilitated by taking samples from the collection sides for GC-MS analysis. The standardized breakthrough time (SBT) when permeation reached 100 ng/cm2/min and the steady state permeation rate (SSPR) depended on A, thickness, and porosity. Only the thinnest glove (Lavender) showed statistically significant (p ≤ 0.05) increased average SSPR for the clenching hand relative to the nonclenching hand and for the ASTM technique. The ASTM test data for the three thickest gloves were not statistically different from those of the robot hand, but differed from the manufacturer’s. More research with different chemicals and higher clenching forces is needed. Clenching forces can enhance the permeation. Workers wearing ultrathin disposable nitrile gloves have a higher potential for chemical penetration/permeation. Company glove permeation data obtained near room temperature may have a longer SBT and lower SSPR than in practice. Double gloving may be advisible in emergencies and for unknown chemicals when no appropriate thicker Chemical Protective glove is available.

“…Nylon can also be resistant, but only at low temperature (< 30°C) [19]. This polymer can consequently be used for intake fuel line, provided the fuel temperature remains low.…”

Résumé -Potentiel de l'éthanol en tant que carburant pour un moteur dédié -Un des défis majeurs de l'industrie automobile est de réduire les émissions de gaz à effet de serre et, en particulier, celles du CO 2 . Plusieurs programmes de recherche sont en cours sur ce sujet, visant la réduction de la consommation des véhicules, mais aussi l'optimisation de la composition des carburants. Il est en effet essentiel de prendre en compte l'ensemble du processus, de la production des carburants aux émissions des véhicules, et un bilan "du puits à la roue" doit être effectué pour chaque technologie.L'éthanol possède des atouts importants pour satisfaire ces nouvelles contraintes : étant extrait de la biomasse, son bilan d'émission du CO 2 "du puits à la roue" est favorable. De plus, ses propriétés, en particulier en termes d'indice d'octane et de chaleur latente de vaporisation, permettent une optimisation du fonctionnement du moteur.La présente étude a pour but d'évaluer la voie éthanol. Les moyens de production sont considérés, en particulier leur bilan énergétique. Les principaux avantages et inconvénients de l'utilisation d'un tel carburant sont résumés. Enfin, nous présentons un exemple des gains qui peuvent être réalisés en optimisant un moteur pour l'utilisation de l'éthanol pur. Un moteur suralimenté de petite cylindrée a en effet été optimisé afin de bénéficier du potentiel de l'éthanol, notamment en termes de réduction du cliquetis. Les performances de ce moteur sont comparées à celles du moteur initial à essence, démontrant que des gains importants peuvent être obtenus avec une telle technologie.
