Material & Methods: The study was a cross sectional study. It was a part of a one day training programme oriented for the up gradation of knowledge about the recent advances in the field of leprosy management and also to highlight the salient features of National Leprosy Eradication Programme (NLEP). All the students who reported on that day were given a questionnaire to be filled before the st...

In this paper, the flexural response of functionally graded plates with porosities is investigated using a novel higher order shear deformation theory, which considers the influence of thickness stretching. This theory fulfills the nullity conditions at the top and bottom of the plate for the transverse shear stresses, thus avoids the need of a shear correction factor. The effective material pr...

The quality of an aggregate in a concrete mixture is one the factors that affect concrete. Geographically, Payakumbuh City and District 50 cities are passed by several rivers where river's products used local community as building material. This research uses quantitative approach, method experiment. results this study found average compressive strength normal fc was 19.3 Mpa at age 14 days usi...

In this paper, we introduce a new enhanced method utilizing the approach of advancing front technique for generating unstructured meshes in the simplified version of ethylene conceptual model. The method is called as Seven Cases Unstructured Triangulation Technique (7CUTT) where it is based on seven categories of cases for element creation procedure and the layer concept for mesh gradation cont...

The assessment of the influence of the work-hardening of material on the optimum die profile and drawing force  in rod drawing process is the main objective of the present paper. The upper bound solution, based on the assumption of perfect plasticity, has been extended to consider the work-hardening of the material during the rod drawing process through curved dies. Analytical results of drawin...

in this paper, the mixed-mode dynamic fracture analysis of a fgm plate is performed using mlpg method also the effect of changes in value and angle of material gradation on the dynamic stress intensity fctor(sif) of mode i, ii, and effective are investigated. to solve time dependent equations that discretized by mlpg method, the central difference method (cdm) and the newmark method are used. a...

The optimal distribution of the reinforcing fibers for stiffening hollow cylindrical composites is explored using the linear elasticity theory. The spatial distribution of the vascular bundles in wild bamboo, a nature-designed functionally graded material, is the basis for the design. Our results suggest that wild bamboos maximize their flexural rigidity by optimally regulating the radial grada...

For the analysis of composite media, three different compatible and mixed finite element formulations are presented which apriori enforce the continuity of stresses as well as displacements at the element interfaces. The formulations are applied for the analysis of hi-material interfaces in two problems often encountered in the field of orthopaedic biomechanics, that is the fixation analysis in...
