magnesium oxide nanoclusters have attracted much attention due to their potential applications to catalysis and novel optoelectronic materials. in the present study, we have studied the electronic and magnetic properties of the stoichiometric magnesium oxide nanoclusters (mgo)n  for n = 2-20. although the binding energy increases with the size of the cluster, it  reaches the asymptotic limit of...

the present investigation entails a procedure by which the surface tension and viscosity of liquids could be redicted.to this end, capillary experiments were performed for porous media by utilizing fifteen different liquids and powders. the time of capillary rise to a certain known height of each liquid in a particular powder was recorded. two artificial neural networks (anns) were designed and...

Introduction: In the past 2 decades, research findings established achievementgoal theory as a powerful framework for conceptualizing difference in thequality of student’s engagement, persistence on task, and academic resilience.So the present study examined the relationship between achievement goalorientations and academic resilience.Method: Participants were 606 students (307 girls and 297 bo...

This exploratory study examines how fire and police departments used online media during the 2012 Hurricane Sandy and how these media can be used to affect trust with members of the public during such an event. Using trust theory, we describe how online communications provide a means for emergency responders to appear trustworthy through online acts of ability, integrity, and benevolence. We co...

Assessing vulnerability is fundamental for efficient risk management and emergency response. Integrating analyses from preparedness and risk reduction to inform the response phase requires that structural information about demographics or industry is combined with specific local information that highlights hotspots or emerging risks in near real-time. Owing to its availability on social media o...
