A FEM-based model to study the behaviour of corroded RC beams shear repaired by NSM CFRP rods technique

This paper presents the main features of finite element FE numerical model developed using the computer code FEMIX to predict the near-surface mounted NSM carbon-fiber-reinforced polymer CFRP rods shear repair contribution to corroded reinforced concrete RC beams. In the RC beams shear repaired with NSM technique, the Carbon Fibre Reinforced Polymer (CFRP) rods are placed inside pre-cut grooves onto the concrete cover of the RC beam’s lateral faces and are bonded to the concrete with high epoxy adhesive. Experimental and 3D numerical modelling results are presented in this paper in terms of load-deflection curves, and failure modes for 4 short corroded beams: two corroded beams (A1CL3-B and A1CL3-SB) and two control beams (A1T-B and A1T-SB), the beams noted with B were let repaired in bending only with NSM CFRP rods while the ones noted with SB were repaired in both bending and shear with NSM technique. The corrosion of the tensile steel bars and its effect on the shear capacity of the RC beams was discussed. Results showed that the FE model was able to capture the main aspects of the experimental load-deflection curves of the RC beams, moreover it has presented the experimental failure modes and FE numerical modelling crack patterns and both gave similar results for non-shear repaired beams which failed in diagonal tension mode of failure and for shear-repaired beams which failed due to large flexural crack at the middle of the beams along with the concrete crushing, three dimensional crack patterns were produced for shear-repaired beams in order to investigate the splitting cracks occurred at the middle of the beams and near the support

Study on behaviour of corroded RC beams repaired in shear with NSM CFRP rods

The near surface mounted reinforcement technique (NSM) is one of the promising techniques used nowadays. In the NSM technique, the Carbon Fibre Reinforced Polymer (CFRP) rods are placed inside pre-cut grooves and are bonded to the concrete with epoxy adhesive. Experimental results obtained on concrete short beams taken from one beam exposed to a natural corrosion for 25 years then repaired only in flexion or in flexion and shear are reported. Results were compared to control beams. One 6-mm-diameter NSM CFRP rod is used to repair the beams. The beams were tested statically in three-point bending up to failure. Results showed that the failure mode of all repaired RC beams in flexion was by shear failure after CFRP rods slip. But the failure mode of the corroded RC beams repaired in both flexion and shear occurred due to concrete crushing. An increase was noticed in the ultimate shear capacity of those repaired beams

The Impact of Mobile Payment on the Financial Inclusion Rates

In this paper, we discuss the impact of the mobile payment system on increasing financial inclusion ratios. We have followed the quantitative and analytical approach to test the studys hypotheses. A questionnaire was designed to consist of two dimensions and (22) questions. The study sample consisted of the Arab Bank and the Housing Bank and the multiple regression is used to test the collected data. The result of the regression equation showed a statistically significant effect of service price, the quality of the service, the ease of using service, and the security of the service provided through the mobile payment system, on the financial inclusion. It is shown that the mobile payment system plays an important role on increasing the financial inclusion rates and is recommended to be included in all banks operating in Jordan. Mobile money adoption, financial inclusion, and the substitutability of mobile money for traditional finance are among the challenges that need additional examination. Regulatory arrangements for institutions offering mobile money services are also highlighted

Multiple Lingual Cusps Trait on Mandibular Premolars and Hypoconulid Reduction Trait on Mandibular First Molar in Living Jordanian Population. Intra- and Inter-trait Interactions

The objective was to determine the expression and fluctuating asymmetry of two dental morphological traits in the living Jordanians: The lingual cusp number on the lower premolars (LP1 and LP2) and the hypoconulid (distal cusp) reduction on the lower first molar (LM1). In addition, both intra- trait and inter- trait interactions were analyzed. Three hundred school children (15.5± 0.4 years) were involved. Impressions for the mandibular dental arches were taken, and dental casts were reproduced. The above-mentioned traits were observed. Paired sample t test and nonparametric corre- lation analysis were used for data analysis. Three-cusped LP1 was found in 11.40 % of the examined students, while the two-cusped LP1 was found in 88.60%. In comparison, the Three-cusped LP2 was found in 61.40% while the two-cusped LP2 was found in 38.60% of the observed subjects. The frequencies of the 4-cusped and 5-cusped LM1 were found to be 8.65% and 91.35%, respectively. Nonparametric correlation analysis revealed positive and statistically significant asso- ciation between the expression of two lingual cusps on LP1 and on LP2 in both genders (p0.05). Bilateralism was highly significant in the tested traits in both genders (p<0.001).This finding might be a sign of relatively low environmental stresses experienced by the living Jordanians and/or great ability of its individuals to buffer the adverse effects of such stresses on dental development. This study is a useful addition to the ex- isting literature in that it examines a previously poorly characterized population and assists in placing the contemporary Jordanian population within the current framework of human population groups globally

Computed tomography scans image processing for nasal symptoms severity prediction

This paper aims to use a new technique of computed tomography (CT) scan image processing to correlate the image analysis with sinonasal symptoms. A retrospective cross-sectional study is conducted by analyzing the digital records of 50 patients who attended the ear, nose and throat (ENT) clinics at King Abdullah University Hospital, Jordan. The coronal plane CT scans are analyzed using our developed software. The purposes of this software are to calculate the surface area of the nasal passage at three different levels visible on coronal plane CT scans: i) the head of the inferior turbinate, ii) the head of the middle turbinate, and iii) the tail of the inferior turbinate. We employ image processing techniques to correlate the narrowing of nasal surface area with sinonasal symptoms. As a consequence, obstruction in the first level is correlated significantly with the symptoms of nasal obstruction while the narrowing in the second level is related to frontal headache. No other significant correlations are found with nasal symptoms at the third level. In our study, we find that image processing techniques can be very useful to predict the severity of common nasal symptoms and they can be used to suggest treatment and to follow up on the case progression

Wireless strain and temperature monitoring in reinforced concrete using Surface Acoustic Wave (SAW) sensors

Monitoring the health of civil engineering structures using implanted deformation, temperature and corrosion sensors would further improve maintenance and extend the service life of those structures. However, sensor integration poses a number of problems, due to the presence of cables and on-board electronics. Passive, wireless SAW sensors offer a very promising solution, here. We used commercial SAW devices mounted on steel rebars to carry out an initial feasibility study. Without cables or embedded electronics, we were able to measure the deformation of a concrete beam subjected to bending load. We were also able to measure the temperature continuously over a three-week period

Docking, synthesis, and anticancer assessment of novel quinoline-amidrazone hybrids

A group of new amidrazone compounds that include a quinoline component was produced through the reaction of hydrazonyl chloride, derived from 6-aminoquinoline, with appropriate secondary cyclic amines. The new compounds were confirmed through 1H-NMR, 13C-NMR, FTIR, and HRMS, and further verified by single-crystal X-ray diffraction. The antitumor potential of the synthesized compounds was tested against lung cancer (A549) and breast cancer (MCF-7) cell lines. Among the compounds, the ethyl carboxylate and o-hydroxy phenyl piperazine derivatives (10d and 10g) exhibited the strongest activity against both cell lines, with IC50 values of 43.1 and 59.1 μM for the lung and breast cancer cell lines, respectively. Moreover, the most potent compounds were subsequently docked into the c-Abl kinase binding site (PDB code: 1IEP) as a possible anticancer mechanism. In-silico ADMET study shows acceptable pharmacokinetic properties, and the toxicity profile for the most potent compounds is non-carcinogenic

Airway Management in COVID-19 as Aerosol Generating Procedure

2020 has seen the whole world battling a pandemic. Coronavirus Disease 2019 (COVID-19) is primarily transmitted through respiratory droplets when in close contact with an infected person, by direct contact, or by contact with contaminated objects and surfaces. Aerosol generating procedures (AGPs) like intubation have a high chance of generating large concentrations of infectious aerosols. AGPs potentially put healthcare workers at an increased risk of contracting the infection, and therefore special precautions are necessary during intubation. The procedure has to be performed by an expert operator who uses appropriate personal protective equipment (PPE). Modifications of known techniques have helped to reduce the chances of contracting the infection from patients. The use of checklists has become standard safe practice. This chapter looks at the current knowledge we have regarding this illness and how we should modify our practice to make managing the airway both safer for the patient and the healthcare workers involved. It addresses the preparation, staff protection, technical aspects and aftercare of patients who need airway intervention. It recommends simulation training to familiarize staff with modifications to routine airway management
