This paper describes a method of performance evaluation and remaining life prediction for an aged reinforced concrete (RC) T-girder bridge by J-BMS RC version via close visual inspection data, and also verifies the assessment results obtained as outputs from the Bridge Rating Expert System (RC-BREX) which is a subsystem of the J-BMS, to evaluate the effectiveness of the system. The Bridge Manag...

مرحله پاکسازی و شکل دهی کانال ریشه از مهمترین مراحل درمانهای اندودنتیکس می باشد. در بسیاری از موارد، فرایندهای فیزیولوژیک و یا پاتولوژیک بر کانال ریشه اثر می گذارند و این مجرا را بسیار باریک می کنند؛ بنابراین استفاده از وسایل و موادی که بتوان با آنها، عمل پاکسازی و شکل دهی کانال را حتی در کانالهای بسیار باریک، بخوبی انجام داد، ضروری به نظر می رسد. هدف از این مطالعه بررسی اثر دو ماده chelating س...

Region covariance (RC) descriptor is an effective and efficient feature for visual tracking. Current RC-based tracking algorithms use the whole RC matrix to track the target in video directly. However, there exist some issues for these whole RCbased algorithms. If some features are contaminated, the whole RC will become unreliable, which results in lost object-tracking. In addition, if some fea...

Despite the increasing numbers of Americans who die in nursing homes (NHs) and residential care/assisted living (RC/AL) facilities, and the importance of religious and spiritual needs as one approaches death, little is known about how these needs are met for dying individuals in long-term care (LTC) institutional settings. This study compared receipt of religious and spiritual help in four type...

We study the linearized stability of shear flow satisfying Navier slip boundary conditions. The Orr-Sommerfeld equation for the plane Poiseuille flow with Navier slip boundary conditions is solved numerically by the Chebyshev collocation method. Our numerical results show that slip at the boundary increases the critical Reynolds number Rc for instability. The dependence of the this critical Rey...

The temperature dependence of the magnetic viscosity coefficient (Sv), the activation volume (Vact) and the coercivity (Hc) were examined for CoCrTa/Cr and CoCrPtTa/Cr thin films in the temperature range from 200 to 423 K. This experiment shows that the medium noise measured for 150 kFCI is approximately proportional to kT/Sv (=Vact X Ms) at 298K. kT/Sv and the temperature variation of coercivi...

The reverberation chamber (RC) has drawn considerable attention as a multipath emulator over the past decade for both passive and active over-the-air (OTA) tests. This thesis is about RCs for OTA applications. The overview of this thesis is given in Chapter 1. Although the main purpose of this thesis is characterizations of MIMO (multiple-input multiple-output) terminals based on RC measurement...

Daily methane production and feed intake were measured on 160 adult ewes, which were the progeny of 20 sires and 3 sire types (Merino, dual-purpose and terminal) from a genetically diverse flock. All animals were housed in individual pens and fed a 50/50 mix of chaffed lucerne and oaten hays at 20 g/kg liveweight (LW), with feed refusals measured for at least 10 days before the first of three 2...

OBJECTIVE This in vitro study evaluated the effect of two different shades of resin cement (RC- A1 and A3) layer on color change, translucency parameter (TP), and chroma of low (LT) and high (HT) translucent reinforced lithium disilicate ceramic laminates. MATERIAL AND METHODS One dual-cured RC (Variolink II, A1- and A3-shade, Ivoclar Vivadent) was applied to 1-mm thick ceramic discs to creat...
