OBJECTIVES We investigated general working conditions in the carpet manufacturing industry and assessed the health risk factors of weavers working in this industry. MATERIALS AND METHODS Noise level, light intensity, temperature and humidity were measured with the help of sound level meter, lux meter and thermohygrometer, respectively at the workplace and the result were subjected to One Way ...

Kenyamanan ruang dapat mempengaruhi perilaku dan psikologis penggunanya. yang perlu untuk diperhatikan diantaranya adalah kenyamanan termal visual. Masyarakat terbiasa menggunakan alat ukur suhu berupa termometer intensitas cahaya lux meter mengetahui kondisi ruang. Alat tersebut menghasilkan besaran terukur tanpa disertai justifikasi apakah memenuhi baku mutu atau tidak. Tanpa pemenuhan mutu, ...

Just as engineers learnt to harness the power of electrons in transistors and microchips—which revolutionized modern society—physicists and biologists are now learning how to tame photons. Their work is generating exciting new possibilities for optical microscopy, with a resolution and level of detail hitherto undreamt of. Biophotonics is a new and exciting research field that is already delive...

Circadian clocks allow organisms to anticipate daily changes in the environment to enhance overall fitness. Transcription factors (TFs) play a prominent role in the molecular mechanism but are incompletely described possibly due to functional redundancy, gene family proliferation, and/or lack of context-specific assays. To overcome these, we performed a high-throughput yeast one-hybrid screen u...

The Vibrio fischeri luminescence (lux) operon is regulated by a quorum-sensing system that involves the transcriptional activator (LuxR) and an acyl-homoserine lactone signal. Transcriptional activation requires the presence of a 20-base inverted repeat termed the lux box at a position centered 42.5 bases upstream of the transcriptional start of the lux operon. LuxR has proven difficult to stud...

Solar Power Plant is a system that able to convert solar energy into electrical energy, it incorporated in several components the form of panels (photovoltaic), battery testing (solar charger controller), inverter, battery, Lux Meter and other accessories. In order get maximum voltage, current, power results, necessary place correctly, by determining angle inclination according previous researc...

PURPOSE To assess the effect of light-rearing history on the photon-capturing ability, amplitude, and kinetics of the fast-PIII response of the retina. METHODS Albino rats were raised on 12-hour light-12-hour dark cycles, with illumination at 3 lux or 200 lux, and killed at approximately 12 weeks. Retinal rhodopsin content was measured spectrophometrically. The morphology of the rod outer seg...
