In this study, we examined the effect of light intensity on colony development regulation in Lasius japonicus Santschi. Queens were collected soon after their nuptial flight Okayama, Japan. They reared under 16L-8D（16 h light, 8 dark）and 12L-12D at 25°C with four conditions: 50, 200, 800, and 3000 lux. The queens started oviposition collection. Thereafter, larvae, pupae, workers emerged 50–800 ...

abstract the ability to monitor particular microorganism in an environment is a difficult task. many genes permit the differentiation of strains by conferring production of unique phenotypes such as bioluminescence [marine bacterial luciferase (luxab)]. therefore, lux-ab gene was cloned into two endemic plant pathogens pseudomonas syringae and ralostonia solanacearum by electrotransformation. l...

This study measured the radiant power (mW), irradiance (mW/cm2) and emission spectra (mW/cm2/nm) of 22 new, or almost new, light curing units (LCUs): - Alt Lux II, BioLux Standard, Bluephase G2, Curing Light XL 3000, Demetron LC, DX Turbo LED 1200, EC450, EC500, Emitter C, Emitter D, KON-LUX, LED 3M ESPE, Led Lux II, Optilight Color, Optilight Max, Optilux 501, Poly Wireless, Radii cal, Radii p...

A face detection experiment based on OpenCV is a technology used to identify and find human faces in digital images or videos. This uses algorithms image processing techniques analyze the pixels an video frame determine if they contain face. The aim of this research effectiveness OpenCV-based using Viola-Jones algorithm with low-intensity brightness environmental conditions. was conducted light...
