Influence of creep forces on the risk of derailment of railway vehicles
(Taylor & Francis, 2009)The derailment mechanism in a railway vehicle is a complex mechanical phenomenon which has been, and still is, the subject of intense research activity due to the serious consequences it can entail. Since Nadal deduced his ... -
Influence of Cryogenic Treatment on Wear Resistance and Microstructure of AISI A8 Tool Steel
(MDPI, 2018-12)The effects of deep cryogenic treatment (DCT) on the wear behavior of different tool steels have been widely reported in the scientific literature with uneven results. Some tool steels show a significant improvement in ... -
Influence of different dietary fats on triacylglycerol deposition in rat adipose tissue
(Cambridge University Press, 2000-11)It has been demonstrated that triacylglycerol (TAG) mobilization from adipose tissue is selective and depends on fatty acid (FA) chain length, unsaturation and positional isomerism. The present study was performed to ... -
