A loop-mediated isothermal amplification (LAMP) assay was developed for rapid, sensitive and specific detection of African swine fever virus (ASFV). A set of LAMP primers was designed based on the sequence of the ASFV gene K205R. Reaction temperature and time were optimized to 64 o C and 60 min, respectively. LAMP products were detected by agarose gel electrophoresis or visually with the additi...

In an ongoing effort towards a more sustainable rare-earth element market, there is high potential for efficient recycling of elements from end-of-life compact fluorescent lamps by physical separation the individual phosphors. this study, we investigate five lamp particles high-gradient magnetic in rotary permanent magnet separator. We thoroughly characterize phosphors ICP-MS, laser diffraction...

Conidia production is a problem in the study of Alternaria alternata from citrus. Thus, this study aimed to compare existing methodologies for conidial production of A. alternata isolated from Ponkan tangerine (2 isolates), Cravo lemon (1 isolate), Pêra orange (2 isolates) and Murcott tangor (1 isolate). The methodologies used were conidia production with 12 and 24 hours under white fluorescent...

The purpose of this study was to quantify the ultraviolet B (UVB) output and in vitro previtamin D(3) synthesis over time from various artificial light sources. Three incandescent lamps, T-Rex Active UVHeat 160 watt spot, T-Rex Active UVHeat 160 watt flood, and ZooMed PowerSun 160 watt flood, and two 1.2 m fluorescent lamps, Sylvania Blacklight 350 BL and ZooMed Reptisun 5.0, were studied. Tota...

ABSTRACT This study aimed to present the design and field test results of an LED (light emitting diode) lamp for integrated pest management (IPM) other entomological studies. The light spectrum LEDs was tuned optimize insect attraction lower energy consumption. An electronic circuit with control software lamp, enabling it operate in standalone mode, automatically identify night day, monitor bat...

Phosphor molecules are excited by ultraviolet light emitted during the steady electrical discharge of the low-pressure gas inside the lamp, and subsequently de-excite via emission of visible light. Some of this light is absorbed and re-emitted by the phosphor. In this problem, assume that there are no losses in this absorption/re-emission. Compare the intensity, brightness and étendue of the li...
