This paper presents an experimental investigation of the shear performance RC beams strengthened with near surface mounted (NSM) carbon fibre reinforced polymer (CFRP) prestressed concrete prisms (PCPs). The behaviour can be affected by several design variables. In this research, effect following parameters were considered: prestress level, inclination and spacing CFRP-PCPs, material type prism...

This article examines experimentally and numerically the flexural performance of low-strength reinforced concrete (RC) beams strengthened using near-surface mounted (NSM) carbon fibre polymer (CFRP) rods. Five RC rectangular were tested in four-point bending until failure. Four these Bottom NSM (BNSM) or Side (SNSM) The results are discussed terms observed damage, load capacity, midspan deflect...

Nipple-sparing mastectomy (NSM) is an increasingly utilized surgical option in managing breast carcinoma; however, data on malignant involvement of a separately submitted nipple margin are scant. Consecutive NSM, including those performed for therapeutic and prophylactic purposes, over a 4-year period (2007-2011), were studied. A separately submitted nipple margin was evaluated by permanent H&E...

Tetrahydrobiopterin, the cofactor required for hydroxylation of aromatic amino acids regulates its own synthesis in mammals through feedback inhibition of GTP cyclohydrolase I. This mechanism is mediated by a regulatory subunit called GTP cyclohydrolase I feedback regulatory protein (GFRP). The 2.6 A resolution crystal structure of rat GFRP shows that the protein forms a pentamer. This indicate...

Current advances in timber engineering with the use of at longer spans necessitate high performance joints. Glued-in rods exhibit axial load capacity and stiffness are suitable for such applications. FRP can increase their durability fire but ways to produce progressive failure mechanisms necessary enhance resilience. In this study CFRP GFRP glued block laminated epoxy investigated under both m...

BACKGROUND Ischemic complications after nipple-sparing mastectomy (NSM) have been associated with numerous variables. However, the impact of NSM flap thickness has been incompletely evaluated. METHODS NSM flap thickness was determined for all NSMs from 2006 to 2016 with available pre- or postoperative breast magnetic resonance imaging (MRIs). Demographics and outcomes were stratified by those...

–The paper presents the results of a study on the performance of Glass Fibre Reinforced Polymer (GFRP) wrapped high strength concrete columns under uni-axial compression. The columns had slenderness ratios of 8, 16, 24 and 32. Three types of wrap materials (Chopped Strand Mat GFRP, Uni-Directional Cloth GFRP and Woven Roving GFRP) were used with 3 mm and 5 mm thicknesses. The columns were teste...

this study was conducted to investigate the effects of dietary nigella sativa meal (nsm) on the growth performance, blood parameters, carcass characteristics, egg yolk cholesterol and meat quality in japanese quail. for this purpose 300 one-day old japanese quail chicks in a completely randomized design was used with five treatments in four replicates )containing 15 birds each(. the experimenta...

• 20 four-point bending tests on timber beams. NSM BFRP and GFRP reinforced beams were studied. The flexural behaviour was improved by FRP reinforcement. A theoretical model able to predict the strength presented. Near Surface Mounted (NSM) fibre polymer (FRP) bars is an effective technique of improving performance Despite potential technique, literature remains limited, whilst there not any st...

OBJECTIVE In our previous study, glass-fiber-reinforced plastics (GFRPs) made from polycarbonate and glass fibers were prepared for esthetic orthodontic wires using pultrusion. These laboratory GFRP wires are more transparent than the commercially available nickel-titanium wire; however, an investigation of the color stability of GFRP during orthodontic treatment is needed. Accordingly, in the ...
