Structural parameters as grain size, dendritic and cellular spacings, segregated products, porosity and other phases are strongly influenced by the thermal behavior of the metal/mold system during solidification, imposing a close correlation between this and the resulting microstructure.Several unidirectional solidification studies with the objecti
The aim is to analyse the parenting styles effects (acceptance, negative control and negligence) on prosociality and aggressive behavior in adolescents through the mediator variables empathy and emotional instability, and also, if this model fits to the same extent when we study adolescents institutionalized due to problems with the law and adolesc
Despite recent issues, Norway spruce remains the most important commercial tree species which might be demanded henceforth for its broadly utilizable wood.Even before foresters faced both the bark beetle outbreaks and spruce decline, spruce monospecific stands were known to be prone also to other damage due to snow and wind.On this basis, measures
According to Howard Garner, Professor of One-of-a-kind Hair-On Hides Cognition and Education at Harvard University, intelligence of humans cannot be measured with a single factor such as the IQ level.Instead, he and others have suggested that humans have different types of intelligence.This paper examines whether students registered in online or mo
The internal electro-hydraulic servo system of a hydraulic press is affected by the non-linear friction, and it becomes non-linear, unstable under vibration.In this study, the dynamic behavior and control of such a system were investigated.A mathematical model was first built and then proportional-integral-derivative control and sliding mode contro
