We have investigated the light intensity distributions of a 7-inch LGP to increase output illuminance uniformity by reducing the bright and dark areas caused by a plurality of LED. We analyzed the effects of the LED–LED gap and LED–LGP space to the light intensity distribution in the LGP inside. We have found that the density function of LGP pattern has a simple exponential terms. We analyzed t...

Aside being a key nocturnal Agricultural pest, the two spotted cricket is an important source of protein for humans and livestock. While control is largely by synthetic pesticides, collection is majorly through hand picking and pouring of water into their burrows. In this study, we determined their phototactic response to LED and incandescent bulb light of different colours. An experiment was s...

Introduction: The aim of this study was to evaluate the influenceof different light curing systems and curing times on the micro-hardness of aresin modified glass ionomer. Methods: Forty two samples of ResinModified Glass Ionomer (RMGI) were prepared using stainless steel cylindrical mold(8 × 2 mm) and randomly divided into six groups of seven. Three groups werecured with a Quartz Tungsten Halo...

introduction: application of light transmitting posts to restore greatly damaged endodontically treated teeth has been increased. it is suspected that light intensity decreases as it passes throughout different materials. this can reduce the degree of conversion required for adequate bond strength throughout the length of these posts. the objective of this study was to evaluate the amount of li...
