background and purpose: occular toxicity is one of the most important complications of hydroxychloroquine. not any type of treatment has so far been found and recommended for this disorder. the purpose of this study was to report some characteristics of patients with hydroxychloroquine induced retinopathy.    materials and methods: from 107 patients with rheumatoid arthritis (ra) and/or systemi...

background: the advancement of technology in recent decades has been lead to use the electrophysiology cardiac devices. although these devices are used increasingly, but the frequency of subclinical infection is unknown. we investigate bacterial infections due to implantable cardioverter defibrillator (icds) in patients with endocarditis. m aterials and methods: population of the study was cons...

abstract purpose-the purpose of this paper is to review a sample of the literature relating to interpretive structural modelling (ism) and its deployment for modelling purposes in the area of supply chain management (scm). design/methodology/approach- the literature is examined from the three perspectives. first, concept of ism and examines ism as modelling technique. second, use of ism by the ...

interpreters have emphasize the necessity of knowing e’rab (diacritic) and syntax in the holy quran and none of them has been doubtful in the significance of the role of e’rab in interpreting. tabarsi in his interpretation book has exerted his efforts in delineating e’rab and after mentioning verses for interpreting, firstly explains lexical elements and then, discusses their e’rab. the signifi...

Seismic upgrading and retrofitting of existing constructions is a pressing need for designers researchers. The necessity efficient seismic upgrading/retrofitting techniques is, therefore, required in seismic-prone countries, such as Italy. In this framework, steelwork has clearly shown many advantageous applications the last century. Nonetheless, if compared to other different technologies, sti...

The seismic vulnerability of existing RC framed buildings in seismic-prone areas requires affordable and practice-oriented solutions for their retrofitting. In this paper, the authors present a retrofitting solution based on combined use cross-laminated timber (CLT) panels asymmetric friction connections (AFCs). AFC connection is activated when force level reaches design threshold. energy dissi...

Seismic risk scenarios are obtained for an informal settlement in Mérida (Venezuela), which is representative of an important number of urban areas in earthquake-prone regions of the developing world. The vulnerability indices of the buildings range between 0.64 and 0.80 on a scale of 0 to 1. In an intensity IX earthquake scenario, more than 32% of the buildings would suffer damage of grade 4 (...

This paper describes an experimental program that deals with retrofitting of infill un-reinforced masonry walls (URM) with Fiber Reinforced Polymer (FRP). The primary objective of this research is to develop a retrofit strategy that while economical will minimize the influence of the retrofit on the overall performance of structural frames in predominant seismic regions. Allowing some damage to...

Models of real systems are of fundamental importance in virtually all disciplines. Models make possible to predict or simulate a system’s behavior. Since the quality of the model typically determines an upper bound on the quality of the final problem solution, modeling is often the bottleneck in the development of the whole system. As a consequence, a strong demand for advanced modeling and ide...
