In this study, the effects of three different viscous damper configurations, chevron, diagonal and toggle, as well as brace stiffness on the performance of brace-viscous damper system in various steel frams under different earthquake records were investigated. A finite element software, ANSYS, is exploited to develop the numerical models. To verify the numerical simulations, their results were ...

14 ________________________________________________________________________ 15 The ca. 1.8 Ga Duck Creek Formation, Western Australia, preserves 1000 m of 16 carbonates and minor iron formation that accumulated along a late Paleoproterozoic 17 ocean margin. Two upward-deepening stratigraphic packages are preserved, each 18 characterized by peritidal precipitates at the base and iron formation a...

Currently, fluid inclusions in halite have been frequently studied for the purpose of paleoclimate reconstruction. For example, to determine air temperature Middle Miocene (Badenian), we examine single-phase primary bottom halites (chevron and full-faceted) near-surface (cumulate) collected from salt-bearing deposits Carpathian region. Our analyses showed that temperatures near-bottom brines va...

We compared folding properties of designed protein Top7 and natural protein S6 by using coarse-grained chain models with a mainly native-centric construct that accounted also for nonnative hydrophobic interactions and desolvation barriers. Top7 and S6 have similar secondary structure elements and are approximately equal in length and hydrophobic composition. Yet their experimental folding kinet...

The B domain of staphylococcal protein A (BdpA) is a small helical protein that has been studied intensively in kinetics experiments and detailed computer simulations that include explicit water. The simulations indicate that BdpA needs to reorganize in crossing the transition barrier to facilitate folding its C-terminal helix (H3) onto the nucleus formed from helices H1 and H2. This process su...

UNLABELLED Reconstructive osteotomies for the treatment of Hallux valgus are among the most prevalent procedures in foot and ankle surgery. The combination of biodegradable materials with an innovative method for fixation by application of ultrasonic energy facilitates a new bonding method for fractures or osteotomies. As clinical experience is still limited, the aim of this study was to assess...

This paper covers the recognition of textual entailment by means of an approach based on knowledge. Our approach consists of two stages. The first stage infers the logic forms from two fragments of text. These logic forms are obtained by analysing the dependency relations between words. And the second stage carries out several methods in order to achieve a score that determines the semantic sim...

In this paper, use of folded patterns as core structures for paper-based flexible wall panels and floorboards building materials was investigated. Effect of changing the geometrical parameters/conditions of the Chevron and the Mating Surfaces Chevron (MSC) patterns on panel core structure performance were studied, aim is to achieve high compressive strength and equal bending stiffness in both t...

This paper presents the design and simulation of an improved electro-thermal micromachined pump for drug delivery applications. Thermal actuators, which are a type of Micro Electro Mechanical system (MEMS) device, are highly useful because of their ability to deliver with great force and displacement. Thus, our structure is based on a thermal actuator that exploits the Joule heating effect and ...
