A trigonometric beam theory (TBT) is developed for the bending analysis of laminated composite and sandwich beams considering the effect of transverse shear deformation. The axial displacement field uses trigonometric function in terms of thickness coordinate to include the effect of transverse shear deformation. The transverse displacement is considered as a sum of two partial displacements, the displacement due to bending and the displacement due to transverse shearing. Governing equations and boundary conditions are obtained by using the principle of virtual work. To demonstrate the validity of present theory it is applied to the bending analysis of laminated composite and sandwich beams. The numerical results of displacements and stresses obtained by using present theory are presented and compared with those of other trigonometric theories available in literature along with elasticity solution wherever possible.

Since the introduction of the implantable cardioverter defibrillator (ICD) by Michel Mirowski in the 1980's, these devices have become an important tenet in management of ventricular arrhythmias1. Numerous observational and randomized trials have demonstrated the superiority of this device over antiarrhythmic drugs in treating ventricular arrhythmias. The clinical implications of these trials are tremendous as sudden cardiac death (SCD) maybe the presenting symptom in these arrhythmias. It is estimated that in the United States alone around 350,000 deaths occur each year due to SCD alone2 . As resuscitation is seldom successful in the community, methods to identify and appropriately treat such patients alone can prevent these events. However, the public health impact of this approach is tremendous, as the ICD is extremely expensive and is out of reach for many individuals. Moreover, not all patients with structural heart disease and ventricular arrhythmias have a malignant outcome. Thus efforts to appropriately stratify patients according to their risk profile and accordingly advocate ICD implant has important fiscal implications for the state with meager health resources, especially in those patients in whom survival benefit with the ICD is modest.

Abstract.Cloud computing is quickly expanding, with applications in practically every industry, including education. E-learning systems often necessitate a large number of hardware and software resources. Many educational institutions cannot afford such investments, thus cloud computing is the best solution. Here, the Matrix Factorisation-based maximum rate recommendation system (MatFac-Maxirate RS) is utilised to recommend the courses for students to choose their career. According to user access, the e-learning application server is acquired from the E-Khool dataset which is subjected to learner or course agglomerative matrix calculation. The E-learning application server is executed based on Minkowski and Kumar Hasebrook's distance to retrieve learner preference items. The recommended course having the maximum rating is considered which is forecasted with matrix factorisation considering the course ID and learner ID. The MatFac-Maxirate RS generated the finest efficacy with the best precision of 88.9%, recall of 88.2% and F-measure of 87.5%. [ABSTRACT FROM AUTHOR]

Background: The choice of sealing material is a crucial factor that influences the outcome of endodontic treatment. Aim: The purpose of this study was to compare the sealing ability of mineral trioxide aggregate (MTA) Angelus, Endocem MTA, and NeoPutty MTA when used as furcal perforation repair materials. Materials and Methods: A total of 45 mandibular molars were used. Root canal treatment was carried out following which standardized furcal perforations were made. The specimens were randomly divided into three groups of 15 teeth each. Group A-Furcal perforation repair by means of MTA Angelus, Group B-Furcal perforation repair using Endocem MTA, and Group C-Furcal perforation repair by NeoPutty MTA. Following the repair procedure, the pulp chambers and access openings were filled with temporary restorative material and immersed in 1% basic fuchsin dye for 24 h. The teeth were sectioned longitudinally and the linear dye penetration was measured using a stereo-microscope. Results: The one-way analysis of variance (ANOVA) revealed a statistically significant difference among the groups (F = 16.15, P < 0.001). On calculating the depth of leakage to the total length of the perforation, it was observed that the mean leakage was 32.83% in Group I, 52.92% in Group II and the lowest, 16.35% in Group III. The ANOVA test reveals a statistically significant difference among the groups (F = 15.92, P < 0.001). Comparing the depth of dye penetration of dye, 33.3% of the Group I samples showed ≥50%, 49%–25%, and <25% dye penetration. Although 56.7% of Group II samples showed ≥50% dye penetration, whereas 63.3% of Group III showed <25% dye penetration. Conclusion: The present study indicated that NeoPutty MTA had the least dye penetration followed by MTA Angelus and Endocem MTA. [ABSTRACT FROM AUTHOR]
