This paper presents new aspects of Anton Tedesko’s design for an important thin shell concrete roof. The study of this roof results from the examination of original engineering drawings and calculations which we present with the goal of promoting a greater understanding of the structural design of a major figure in the tradition of 20th century building. CE Database subject headings: Thin shell...

controlled vocabularies have been frequently used in information retrieval systems. control of the vocabularies and evaluating the utility of their terms are two critical questions. this research aims at the development of persian subject headings through statistical analyses. the current research was conducted on more than 450,000 records extracted from the electronic version of national bibli...

This review is an attempt to untangle the complexity of transtibial prosthetic socket fit and perhaps find some indication of whether a particular prosthetic socket type might be best for a given situation. In addition, we identified knowledge gaps, thus providing direction for possible future research. We followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) ...

AIM To assess how the various methods of intracanal reinforcement (short root canal posts) performed in their clinical and radiographic outcomes for restoring grossly broken down primary anterior teeth after pulpectomy for 1 year or longer follow-up period. MATERIALS AND METHODS Literature search of electronic databases (Sept 2013) and various journals (1980-Sept 2013) using medical subject h...

We report on a simulation study of the performance of the North Tower (WTC-I) of the World Trade Center complex during the impact of American Airline Flight 11, on September 11, 2001. We discuss impact damage the structural core might have sustained and its possible behavior under structural and thermal loading. Our simulations indicate that the worst damage to the core structure was in stories...
