TL;DR: The application of textile reinforced mortar (TRM) as a means of increasing the shear resistance of reinforced concrete members is investigated in this article, where it is concluded that textile-mortar jacketing provides substantial gain in shear resilience; this gain is higher as the number of layers increases and is sufficient to transform shear type failure to flexural failure.
Abstract: The application of textile reinforced mortar (TRM) as a means of increasing the shear resistance of reinforced concrete members is investigated in this study. TRM may be considered as an alternative to fiber reinforced polymers (FRP), providing solutions to many of the problems associated with application of the latter without compromising much the performance of strengthened members. Based on the experimental response of reinforced concrete members strengthened in shear it is concluded that textile-mortar jacketing provides substantial gain in shear resistance; this gain is higher as the number of layers increases and, depending on the number of layers, is sufficient to transform shear-type failure to flexural failure. TRM jackets were provided in this study either by conventional wrapping of fabrics or by helically applied strips. Both systems resulted in excellent results in terms of increasing the shear resistance. However, compared with their resin-impregnated counterparts, mortar-impregnated textiles may result in reduced effectiveness. Modelling of reinforced concrete members strengthened in shear with TRM jackets instead of FRP ones is presented by the authors as a rather straightforward procedure by the proper introduction of experimentally derived jacket effectiveness coefficients. From the limited results obtained in this study it is believed that TRM jacketing is an extremely promising solution for increasing the shear resistance of reinforced concrete members.

TL;DR: In this article, the performance of exterior reinforced concrete (RC) joints strengthened with fiber reinforced polymers (FRP) under simulated seismic load was examined through 2/3-scale testing of 18 exterior RC joints.
Abstract: The results of a comprehensive experimental program, aimed at providing a fundamental understanding of the behavior of shear-critical exterior reinforced concrete (RC) joints strengthened with fiber reinforced polymers (FRP) under simulated seismic load, are presented in this study. The role of various parameters on the effectiveness of FRP is examined through 2/3-scale testing of 18 exterior RC joints. Conclusions are drawn on the basis of certain load versus imposed displacement response characteristics, comprising the strength (maximum lateral load), the stiffness, and the cumulative energy dissipation capacity. The results demonstrate the important role of mechanical anchorages in limiting premature debonding, and they provide important information on the role of various parameters, including: area fraction of FRP; distribution of FRP between the beam and the column; column axial load; internal joint (steel) reinforcement; initial damage; carbon versus glass fibers; sheets versus strips; and effect of transverse beams.

TL;DR: LSG and LRYGB are equally safe and effective in the amelioration of comorbidities, while LSG is associated with fewer postoperative metabolic deficiencies, without the need of supplementation at 3 years follow up on weight reduction.
Abstract: Background
Laparoscopic Roux-en-Y gastric bypass (LRYGB) is currently the gold standard bariatric procedure for the treatment of morbid obesity. Laparoscopic sleeve gastrectomy (LSG) is a relatively innovative procedure which has been increasingly applied lately as a sole bariatric procedure. A randomized trial was conducted in a Greek population to evaluate perioperative safety and 3-years results.

TL;DR: Complications after PNL can be kept to a minimum in experienced hands with the development of new techniques and improved technology and a modified procedure-specific Clavien classification should be established that would need to be validated in prospective trials.
