every time a visitor sets foot in an ecotourism site, he/she causes a negative impact. this is an unavoidable fact. an ecotourism program initiates many public use activities that will have impacts ,both positive and negative. an ecotourism management plan seeks to minimize the negative impacts.therefore monitoring and managing of visitor impacts are fundamental ecotourism management strategie...

Theoretical study of non-Newtonian effects of second-order fluids on the performance characteristics of inclined slider bearings is presented. An approximate method is used for the solution of the highly nonlinear momentum equations for the second-order fluids. The closed form expressions for the fluid film pressure, load carrying capacity, frictional force, coefficient of friction, and centre ...

Steel Plate Shear Wall (SPSW) is made from thin steel plate which in turn are framed by the beams and columns of structural system. In recent year they are proved to be very effective and economical for resisting lateral loads such as earthquake and wind loads.The present work targets to study the behaviour of single frame SPSW with different plate thicknesses, rigid and non-rigid frame members...

Abstract. The modern unification of the European standards EUROCODE requires securing a constant quality of metallurgical production in the EU countries. In this paper, experimentally found statistical characteristics of yield stress, ultimate tensile strength and ductility of Czech and Austrian steel are presented. In the probabilistic reliability analysis, the experimentally found yield stres...
