Abstract Trafficking in human beings is closely related to the cross-border movements of people and smuggling migrants. However, victim-centred regulatory approach this reality internationally adopted places protection victims’ rights at centre demands an institutional response focused on their detection protection. In order determine whether type being Spain, online survey was conducted 150 bo...

aquaculture is among the oldest occupations of human being. over the past quarter of century, the aquaculture industry has grown rapidly. the effect of water containing sodium sulfate on long term compressive strength of concrete of fishing ponds and channels is investigated in this paper. aim of this paper was to analyze the strength of concrete channels and of aquaculture which are in direct ...

The strength of concrete is a function of the proportions of the constituent materials, namely, cement, water, fine and coarse aggregates. The conventional methods used to determine the mix proportions that will yield the desired strength, are laborious, time consuming and expensive. In this paper, a mathematical method based on modified regression theory is formulated for the prediction of con...

superior performances of self-compacting concrete (scc) in fresh state to achieve a more uniform distribution encourage the addition of fibers in concrete which is a motivation for structural application of fiberreinforced concrete. fiber addition reduces the workability of self-compacting fiber reinforced concrete (scfrc). to provide required workability of the scfrc, more paste is needed in t...

   This paper reviews some progressive studies and innovations in cement and concrete materials in nano field. Due to the widespread acceptance of the special properties of nano materials and using them for engineering concrete performance, understanding and directing their properties are not achievable without instructing concepts and investigating interactions among components. Due to ach...

Social computing systems collect, aggregate, and share usercontributed content, and therefore depend on contributions from users to function properly. However, humans are intelligent beings and cannot be programmed to behave; system designers must provide incentives to encourage users to contribute. We explore the behavioral consequences of one simple incentive mechanism: require users to contr...

My goal is to outline an evolutionary neuropsychological foundation for spiritual and religious experiences. Central to this account are concepts from archetypal psychology, which, on the one hand, explain the structure of common religious experiences, but, on the other, are grounded in ethology and evolutionary biology. From this it follows that certain religious phenomena are objective, in th...

Today due to increasing development and importance of petroleum activities andmarine transport as well as due to the mining of seabed, building activities such as construction of docks, platforms and structures as those in coastal areas and oceans has increased significantly. Concrete strength as one of the most important necessary parameters for designing, depends on many factors such as mixtu...
