Turpentine as an additive for diesel engines: experimental study on pollutant e...
Chivu, Robert Mădălin; Martins, Jorge; Popescu, Florin; Uzuneanu, Krisztina; Ion, Ion V.; Gonçalves, Margarida; Codau, Teodor Cezar; Onofrei, ElenaThe need for reducing fossil fuel consumption and greenhouse gas (GHG) emissions in internal combustion engines has raised the opportunity for the use of renewable energy sources. For the progressive replacement of fossil fuels like diesel, those derived from the sustainable management of forest resources may be a good option. In Portugal, pine trees (pinus pinaster) are among the most widely cultivated tree sp...
Investigating the effect of moisture on the thermal comfort properties of funct...
Catarino, André P.; Rocha, Ana; Onofrei, ElenaThermo-physiological wear comfort is mainly determined by the thermal and moisture performance of clothing. Moreover, moisture is widely recognized as one of the most important factors contributing to discomfort sensations. Functional yarns with a thermo-regulating effect improve thermal and moisture performance of fabrics, but the integration of elastic yarns into the fabric structure can impair thermo-physiol...
Thermal comfort properties of knitted fabrics made of elastane and bioactive yarns
Onofrei, Elena; Rocha, A. M.; Catarino, André P.In the last years an increasing improvement in qualitative standards of human lifestyles determined a greater sense of comfort for the textiles used in indoor and outdoor activities. These textiles must fulfill the consumer requirements of comfort, fit and easy of movement. New fibres have been produced and many studies are carrying on for fabric structure optimization in order to obtain functional products. Th...
