English in Nepal is taken as a foreign language but ground reality shows that it one of the primary and dominant languages, which extensively used various spheres such academic institutions, technology, business, tourism, social gatherings, daily lives. This study attempts to analyze growing craze use Nepali public domains. We collected qualitative data from both secondary sources. purposively ...

Crazing is a failure mode of bulk polymers and occurs under predominant uniaxial tensile load when the bulk eventually forms denser ligaments (or fibrils) while preserving its continuity. The bridging of cracks by such fibrils is an importantmechanism for energy dissipation and toughening in thermoplastic polymers. However, craze phenomena are not observed in thermosetting polymers such as epox...

The pandemic has accelerated urban people to conduct transactions, commerce, business and online movement. However, before outside the pandemic, there is a trend towards increasing religiosity, hijab as fashion trend, coffee craze, corporatization of warteg, tendency shop via smartphones, fondness for antiques, sluggishness in contemporary art, which should be noted. There L-project, an art pro...

fast fracture is one of the major failure modes in brittle polymers. generally, crack growth in these polymers may occur under combined tensile-shear loading. however, the fracture test data reported previously for some dental restorative resins can not be predicted by using the available fracture criteria.in this paper, a modified fracture criterion is used for estimating the fracture load for...

INTRODUCTION The aim of this study was to compare the formation of dentinal crack and craze lines in the root dentin during root canal preparation with three different NiTi endodontic systems, naming Reciproc (RCP), ProTaper Universal (PTU) and Mtwo. METHODS AND MATERIALS One hundred extracted mandibular premolars with single canals were selected and decoronated. The teeth were randomly divid...

The purpose of this study was to compare the incidence and longitudinal propagation of dentin defects after gutta-percha removal with hand and rotary instruments using microcomputed tomography. Twenty mandibular incisors were prepared using the balanced-force technique and scanned in a 19.9 μm resolution. Following filling with the lateral compaction technique, gutta-percha was removed with Pro...

The purpose of this study was to compare the incidence of dentinal defects (fractures and craze lines) after canal preparation with different nickel-titanium rotary files. Two hundred sixty mandibular premolars were selected. Forty teeth were left unprepared (n = 40). The other teeth were prepared either with manual Flexofiles (n = 20) or with different rotary files systems: ProTaper (Dentsply-...
