Abstract In this paper, an overview focusing on the bond behavior of recycled coarse aggregate concrete (RAC) with steel bar is carried out. The results show that failure modes RAC specimen were not only influenced by a single factor, it necessary to comprehensively consider influence various factors specimen; diameter, cover diameter ratio and replacement rate RCA all affect load-slip curve Bo...

A 76-year-old woman was referred to the National Cancer Center Hospital for treatment of a large laterally spreading tumor (granular-type) of the rectum (●" Fig.1a). The lesion was >10cm in diameter. There were no endoscopic findings suggesting submucosal invasion, and therefore endoscopic submucosal dissection (ESD) was chosen as radical treatment. The ESD procedure was performed, and a en blo...

Three different samples of Ti -6Al-4V of size 10mm diameter x15mm height compressed at a strain rate of 102 sec -1 in a 100KN servo hydraulic machine (DARTEC, UK make) with three different initial temperatures. First specimen of Ti-6Al-4V was compressed at an initial temp 1123K from initial length 15 mm to 10mm then the temperature was reduced to 1073K and compressed to a length of 7 mm now the...

The patient was a 72-year-old man with a mass in his right axilla for 1 year. The tumor was painless, mobile, and slowly increasing in size; at its largest it measured 3 cm in diameter and was in a subcutaneous location. The clinical presumptive diagnosis was epidermoid cyst, mucocele, adnexial tumor, and nodule. The lesion was excised under local anesthesia. The resected specimen consisted of ...

Three-dimensional residual stress mapping of an aluminum 2024-T3 arcan specimen, butt-welded by the friction stir technique, was performed by neutron diffraction. Results indicate that the residual stress distribution profiles across the weld region are asymmetric with respect to the weld centerline, with the largest gradients in the measured residual stress components occurring on the advancin...

INTRODUCTION To evaluate the effect of two different post space diameters and related resin cement film thicknesses on the bond strength of a polyfiber post. MATERIALS AND METHODS A total of 48 premolars were randomly divided into two according to the post space diameter: 1.1 mm and 1.5 mm. Then each group was divided into three sub-groups according to luting cement used: RelyX U100, Panavia ...

Several surface modification techniques such as ion implantation, surface laser melting, have been employed to improve pitting corrosion resistance of stainless steel. Electropolishing is a technique in which the surface roughness is eliminated through a selective electrochemical dissolution. The effect of electropolishing on pitting corrosion of 304 stainless steel (SS) was investigated employ...

Let G be a connected graph of order n . The Steiner distance d ( S ) set vertices is the minimum size subgraph that contains all For k ≤ , -diameter sdiam maximum among sets generalises classical diameter, which coincides with 2-diameter. problem determining given order, diameter and degree was first studied by Erdös Rényi. In this paper we consider corresponding for -diameter. Δ ∈ N define e a...
