Comparative Study of the Concept of Death in Children Based on the Nagy and Piaget Cognitive Pattern: Directed content Analysis

Introduction: The death of an important person in every person's life is the hardest event that can experience. In the meantime, the bereaved children   of a vulnerable population are at risk of social and psychological harm. The aim of this study was to investigate how children understand the concept of death and its components in cognitive-evolutionary periods based on Piaget's theory and Nag...

Analytic Erdös-Turán conjectures and Erdös-Fuchs theorem

We consider and study formal power series, that we call supported series, with real coefficients which are either zero or bounded below by some positive constant. The sequences of such coefficients have a lot of similarity with sequences of natural numbers considered in additive number theory. It is this analogy that we pursue, thus establishing many properties and giving equivalent statements ...

Intrahepatic ramifications of the portal vein in the horse

The ramifications of the portal vein in the liver of horses were studied by using corrosion casting and gross dissection. The portal vein in the horse supplies the hepatic lobes by six major branches. The right lobe is supplied by three main branches, namely the dorsal diaphragmatic, the right caudodorsal and the right intermediate branches. The left branch supplies the left lateral and medial ...
