background welding is defined as linking two metals with a local conjunction in sufficient thermal, pressing and metallurgical condition. there are several methods for linking two metals in welding. objectives welding is one of the professional jobs in iran, yet there have not been considerable studies on its harmful effects. the current study aimed to compare lung functional tests between weld...

in order to study planting date impacts and ending season drought stress  on grain yield and  gaining weight  rate  and wheat filling period characteristics in new advanced bread wheat genotypes ,this research  is done by using plan statistical  of spilt plot  in form of complete random blocks basic  plot with 3 replications in both common separated irrigation  and ending season drought  stress...

In this study, the progressive collapse potential of seismically designed steel plate shear wall (SPSW) systems is investigated using the alternate path method, and their performances are compared with those of the conventional special moment frame (SMF) systems. Nonlinear static and dynamic analyses are conducted to follow the progressive collapse of the structures, and their ability of absorb...

An innovative type called "butterfly-shaped links steel plate shear wall (BLSPSW)" was proposed as a lateral load resisting system. In this novel system, by creating butterfly-shaped links in the four sides of the web plate, the lateral load resisting mechanism is not the development of a diagonal tension field on the web plate (similar to Conventional SPSWs), but the capacity of the system is ...

Recent work has considered the possibility of utilizing symbolic representations of controlled chaotic orbits for communicating with chaotically behaving signal generators. The success of this type of nonlinear digital communication scheme relies on partitioning the phase space properly so that a good symbolic dynamics can be defined. A central problem is then how to encode an arbitrary message...

Background With an increasingly aged, frail population that holds a disproportionate amount of wealth, clinicians (especially those with expertise in older adults) may be asked with more frequency to offer a clinical opinion on testamentary capacity (TC), the mental capacity to make a will. Method This paper reviews the legal criteria as well as the empirical research on assessment tools for ...
