construction industry consists of several phases in which a variety of stakeholders are involved. as construction projects are becoming larger, more complex and more diverse, the design phase has been more important factor for the success of projects than ever before. however, it is considered that most of design work occurred in actual design process is intangible. such recognition makes the d...

A calculation is presented for the irreversible entropy production that accompanies the imposition of a pressure perturbation on a two-phase medium consisting of a dilute suspension of one phase (as droplets or snowflakes) in another (liquid) phase of significantly different composition. No metastability is allowed, and the relaxation process is then dominated by the finite diffusivity of solut...

in this paper, the effect of autofrettage process parameters on the ultimate pressure that functionally graded spherical vessel can tolerate are investigated. fgm properties and autofrettage pressure are considered as important parameters. assumptions are variation of properties of fgm in radial direction, the residual stress in the absence of bauschinger effect with the operation of variable m...

in the presence of uncertainty about what a country can be good at producing, there can be great social value to discovering costs of domestic activities, because such discoveries can be easily imitated. two failures of the laissez – faire outcome are being highlighted: there is too little investment and entrepreneurship ex ante, and too much production diversi-fication ex post. optimal policy ...

Statistical business process is variously designed and implemented in different organizations. This makes it difficult to exchange the knowledge, benefit from the good practices and the cooperation between national and international organizations. In order to solve this problem and help statistical organizations discuss developing statistical metadata systems, General Statistical Business Proce...

Abstract Gas to liquid (GTL) process involves heterogeneous catalytic chemical reactions that convert synthesis gas to hydrocarbons and water vapor. A three phase reactor, called Low temperature Fischer-Tropsch (LTFT) is commonly applied for GTL process. In this reactor the gaseous phase includes the synthesis gas, light hydrocarbons and water vapor, the liquid phase is a mixture of the h...

this research considers the recognition and evaluation of identity formation process in new towns, with special reference to hashtgerd new town in iran, located in some 65 kilometers distance on the west of tehran, the capital. the construction of hashtgerd new town and people settlement was started in more than 15 years ago. the concept of city identity, its divisions and elements, explanation...

In this paper some basic aspects of the theory of graded consequence are reconsidered, based on many results that appeared since the inception of graded consequences in 1986. Relationships of the notion of graded consequence with the notions of consequence in many-valued and fuzzy logics are discussed. Following this, a detailed study is carried out on the necessary conditions that follow from ...

clopidogrel, an inhibitor of platelet aggregation, selectively inhibits the binding of adenosine diphosphate (adp) to its platelet receptor and the subsequent adp-mediated activation of the glycoprotein gpiib/iiia complex, thereby inhibiting platelet aggregation. oral bioavailability of clopidogrel is very low (less than 50%), due to its poor water solubility. the aim of this investigation was ...
