In these lectures I will study some properties that are shared by many glassy systems. I will shown how some of these properties can be understood in the framework of the mean field approach based on the replica method and I will discuss which are the difficulties which we have to face when we apply the replica method to realistic short range models. We finally present a partially successfully ...

Increased rate of exam failure in mathematics is observed at many educational institutions in the last years. Various approaches have been applied to resolve that problem. Some of them like e-learning methodologies and intelligent tutoring systems are more technologically oriented while others focus on face to face communications and group study techniques. In this work we consider a way to adj...

A new simple analytical model for prediction of cooling rate in the solidification process based on the local heat flux density extracted during solidification is introduced. In the modeling procedure, a solidifying control volume is considered in the mushy zone in which a heat balance equation is used to derive the present model. As the local heat flux density is a measurable parameter, the pr...

Many adolescents experience difficulties with traditional face-to-face mental health care approaches. Personal Investigator (PI) is a 3D computer game specifically designed for use in adolescent interventions. The game implements a model of Solution Focused Therapy. It aims to assist in easing the difficulties experienced by adolescents with direct face-to-face approaches. In sessions a therapi...

This article focused on issues relating to the career transitioning of students with visual impairments (SVIs). This article utilized a narrative-integrative research design.  Literature review shows that many educators and other stakeholders in the transition process are still unaware of the difficulties that SVIs experience.  Literature shows a mixed attitude on the part of some educators tow...

In 1890, Coley observed that cancer patients who developed infections had smaller tumors. From this, he developed Coley’s toxin and treated tumors with injections of infectious materials. In 1960s,  Mahaley used monoclonal antibodies to treat central nervous system(CNS)  tumors, that research and clinical investigations in brain tumor immunotherapy became a serious undertaking. ...
