on the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
15 صفحه اولTranscatheter fiber heart valve: Effect of crimping on material performances.
Transcatheter aortic valve implantation (TAVI) has become a popular alternative technique to surgical valve replacement. However, the biological valve tissue used in these devices appears to be fragile material in the long term particularly due being folded for low diameter catheter insertion purposes and when released in a calcified environment with irregular geometry. Textile polyester materi...
متن کاملExperimental study of the thermal performances of a composite roof including a reflective insulation material under tropical humid climatic conditions
This paper deals with the evaluation of the outdoor performances of a composite roof, composed of a corrugated iron rooftop, a radiant barrier and a ceiling made of wood, each component being separated by an air space. This assembly is mounted on a small-scale test cell, named Isotest, designed and set up for research purposes. Isotest is installed on an experimental platform, dedicated to the ...
متن کاملEffects on electrochemical performances for host material caused by structure change of modifying material.
High ionic conductive lithium niobium oxides were selected as the modifying material to investigate the effects on the electrochemical performances for host material LiNi1/3Co1/3Mn1/3O2 caused by the structure change of the modifying material at various calcination temperatures and modifying amounts. X-ray diffraction (XRD) studies revealed that the structure of the modifying material was singl...
متن کاملLaser-powder-material interactions in the laser cladding process
In this paper we present briefly two possible approaches for modelling the laser cladding process. The first approach is 2D and consists in finding the shape of the molten pool given the fraction of the laser power which is available at the surface of the workpiece and given the amount of powder sticking to the molten pool. The powder reaching the workpiece is assumed to melt instantaneously at...
