background and aim : )co-op( is a client-centered cognitive-based approach that focuses on individual abilities to achieve his/her functional goals. this approach is based on the assumption that cognition plays an important role in acquisition of functional skills, and is used to gain new skills and improve previous skills. the purpose of this paper is to systematically review studies on co-op ...
background: early puberty is a common worldwide problem. different parameters as genetics, metabolic diseases, obesity, as well as environmental factors may affect the age of puberty. this systematic review aims to survey the related literature on the effects of environmental pollutants and especially organohalogens and phthalates on early puberty. materials and methods: a systematic review of ...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
