Chemical composition and processing effects on the pseudoelastic response of α’ ferromagnetic martensite
Processing effects caused by homogenization heat treatment, hot rolling and solution treatment in three Fe-Cr-Ni-C alloys, with different Ni amounts, were analysed by optical and scanning electron microscopy. X-Ray diffraction (XRD), magnetic hysteresis data, Vickers micro-hardness and micro-indentation measurements were used in order to reveal chemical composition and processing effects. Dendrite fragmentation, caused by hot rolling and thermoelastic

Possible relationships between tropospheric and stratospheric temperatures in the Northern Hemisphere and atmospheric oscillations, solar and geomagnetic activity are described, using correlation analysis. The dependence of correlations on season, solar activity level and phase of the Quasi Biennial Oscillation (QBO) is also investigated. An important finding is that the variability of the hemispheric tropospheric temperature is well connected to

In a modern and postmodern conception of the educational process, teaching-learning means search, understand and interpret of its own, and the student has an active role, the educational desire being the demonstration of certain skills, attitudes, competencies. At the same time, curricula contents are diverse and synthetic, therefore instructive-educative strategies are educational dominantly, applicable both, independently and in groups. To achieve

Academic learning improves and continues the scholar learning, being distinguished by both the specificity that it involves higher/university education compared to pre-university education, and especially, the characteristics of personality development in every stage of life. In academic environment, for students engaged in education, the sources of stress can be found either at the level of learning context people in the close group, teachers,
Read moreApproaches to learning process: superficial learning and deep learning at students
The forms of learning are varied, among them we could count superficial and deep learning. The theme proposed is an extension of our doctoral research concerns in Educational Sciences, concerns regarding learning activity as an activity under a continuous process of restructuring / reconsideration, through the influence of the new postmodern paradigms in education. Based on the comparison of the two forms, we find that each is associated with other
