Abstract: We consider convex functions modeling flows in an arborescent network. The notion of majorization on trees is used to study some classical convexity results in this framework.

We combine some important theoretical mathematical results with practical aspects from engineering in a nice framework ofspiders, which forms a space with global nonpositive curvature. Some concavity properties into such framework are derived. As an application, we consider a mathematical model for an engineering problem. More precisely, we are trying to model the behaviour of tension forces appearing in a metallic roof supported on seismic isolators. In fact, we are looking to find the properties of good seismic isolators in order to reduce the destructive power of an earthquake. The answer consists of a concave behaviour in terms of the displacements on the 3D axes of the Cartesian system.

Domestic violence is an offence and is one of the major causes for increase of crime index of the state. it is a social phenomenon that has caught the attention of all and sundry in the recent times. The term domestic includes violence by an intimate partner wherever this violence takes place and by whatever forms. And also this violence is a pattern of assault and coercive behavior including physical, sexual and psychological attacks, by a person against his/her own intimate partner. This study sought to evaluate and examine the problem of domestic violence in general. the author tries to explain the root causes of domestic violence which includes certain factors such as individual, relationship, community, societal, legal and political factors. These factors are responsible for domestic violence and its consequences on the victim's psychological as well as physical health in day to day life. Key words: domestic violence, forms, risk factors, consequences, Iraq.
