The attraction of adult Chironomus salinarius to incandescent 3-W lamps of 7 different colors used in CDC traps was studied on a small island in the lagoon of Venice, Italy. An ANOVA indicated that the lamp type was a highly significant (P < 0.01) factor associated with differences in light trap catch (28% of total variation), as well as catch per lux (18% of total variation). The white lamp at...

Flowering of chrysanthemum plants under short photoperiods, as is well known, is prevented when the plants are illuminated near the middle of the long night. Such illumination inhibits flowering whether it is given continuously or intermittently, and whether it comes from incandescent or from fluorescent lamps. We discovered, however, that fluorescent light applied intermittently (cyclically) t...

Abstract Spectral irradiance scale in the wavelength range from 250 nm to 2500 was realized at National Institute of Metrology (NIM) on basis a large area tungsten carbide–carbon (WC-C) high temperature fixed point blackbody, which is composed 14 mm diameter WC-C cell and variable blackbody BB3500MP as furnace. A series 1000 W FEL halogen lamps were used transfer standards. The new spectral com...

In the present work, the ZnFe2O4 nanoparticle has been successfully synthesized. The obtained sample was characterized by X-ray diffraction (XRD), emission scanning electron microscopy (FE-SEM) and its optical property was examined by UV-Vis spectrophotometer. FE-SEM revealed that the particle size of the ZnFe2O4 of about 47 nm was synthesized. The photocatalytic performance under UV-Vis and vi...

Spectrometer calibration and measurements of spectral radiance are often required when performing ground, aerial, and space measurements. While calibrating a spectrometer in the field using an integrating sphere is practically unachievable, calibration against a quartz halogen (QH) lamp is a quite easy and feasible option. We describe a calibration protocol whereby a professional QH lamp, opera...

BACKGROUND Aberrantly methylated genes represent important markers for cancer diagnosis. We describe a multiplex detection approach to efficiently quantify these markers for clinical applications such as colorectal cancer screening. METHODS Quantitative allele-specific real-time target and signal amplification (QuARTS) combines a polymerase-based target amplification with an invasive cleavage...

The substrate heater designed for this investigation is a front side substrate heating system. It consists of 10 conventional tungsten halogen lamps and an aluminum reflector, total input electrical power of 5 kW. The substrate is heated by means of a radiation from conventional tungsten halogen lamps directed to the substrate through a glass window. This design allows easy replacement of the l...

This paper was investigated the electrical properties for optimal operating conditions of monocrystalline silicon solar cell. The output of electricity for monocrystalline solar cell was investigated according to the distances between solar cell and halogen lamp and to the resistances by the variable resistor.
