Lighting is an essential element for human life. Based on the decree of Minister Health No.1405/Menkes/SK/XI/2002 Date: 19 November 2002 concerning requirements and procedures implementation healthy working environment. Indonesian National Standard 16-7062-2004 states that quality inadequate lighting gives bad effects visual function, environment around workplace, psychological aspects can be f...
Background and aims: When speaking of stress, it is considered to be the most negative aspects. Stress can develop some of physical, psychological and social illness. Too much stress can reduce performance and increase in accidents in the workplace. In the Cement production lines, there are many deleterious effects that play in outbreak of stress and endanger the health of workers. Methods: ...
The key riboflavin synthesis genes are located immediately downstream of luxG in the lux operon from Photobacterium leiognathi. It is of interest that a site capable of forming a rho-independent terminator does not appear to be present between luxG and ribE in our previous data. These results raise the question of whether the transcription of lux and rib genes is integrated or not. In order to ...
The aim of this study was to examine the effects of salinity and light intensity on the chlorophylls, ?-carotene and protein contents in Dunaliella salina Teod. The algae were grown in inorganic medium containing 0, 0.9, 1.8 (control), 2.6 and 3.5 M NaCl under three illumination regimens [4500 (control), 9000 and 11000 Lux]. The results showed that most electrophoresis protein bands were separa...
aims: work proper lighting means a safe, healthy and comfort conditions for work under a lighting system that includes qualitative and quantitative features. this study aimed to evaluate the surface local lighting of works and eye fatigue among research and development staffs of an automotive industry. instrument & methods: in this descriptive study in research and development department of an ...
Indonesia is a megadiverse country. Butterflies become one of the Indonesian diversities. has second-highest butterfly species in world with more than 2000 species. Flower plants are used by butterflies as hostplants and foodplant. The aims this research were to know butterflies’ diversity food Mount Muria at Kudus City, Central Java. quadran sampling transect method three stations (along 2 km)...
Vibrio fischeri induces both anaerobic respiration and bioluminescence during symbiotic infection. In many bacteria, the oxygen-sensitive regulator FNR activates anaerobic respiration, and a preliminary study using the light-generating lux genes from V. fischeri MJ1 cloned in Escherichia coli suggested that FNR stimulates bioluminescence. To test for FNR-mediated regulation of bioluminescence a...
The Large Underground Xenon (LUX) experiment is a dual-phase xenon time-projection chamber operating at the Sanford Underground Research Facility (Lead, South Dakota). The LUX cryostat was filled for the first time in the underground laboratory in February 2013. We report results of the first WIMP search data set, taken during the period from April to August 2013, presenting the analysis of 85....
Red light (RL) marked higher weight gain (WG) and preference of broilers compared to other light colors. This study aimed to investigate how different intensities of RL affect the performance, behavior and welfare of broilers. RL treatments were T1 = high intensity (320 lux), T2 = medium intensity (20 lux); T3 = dim intensity (5 lux), T4 = control/white light at (20 lux) provided on 20L:4D sche...
