The Biogents® Sentinel (BGS) trap is the standard tool to monitor adult Aedes (Stegomyia) albopictus (Skuse) (Diptera: Culicidae), the Asian tiger mosquito. BGS traps are commonly placed in residential properties during surveillance operations, but locations within properties may have significant differences in ambient light, temperature, and humidity (e.g. between a sunlit lawn and shady under...

Influence of temperature on photoconductivity of single Se nanowires has been studied. Time response of photocurrent at both room temperature and low temperature suggests that the trap states play an important role in the photoelectrical process. Further investigations about light intensity dependence on photocurrent at different temperatures reveal that the trap states significantly affect the...

the main vector of malaria in europe and palearctic region is anopheles maculipennis complex. in order to determine the survival rate of an. maculipennis s.l. this study was carried out in garaboteh (zanjan province, iran) in july 2003. in this study anophelines were sampled for 31 consecutive days from five fixed animal shelters and five light traps. out of 24481 collected an. maculipennis s.l...

We present the design, implementation and characterization of a dual-species magneto-optical trap (MOT) for fermionic Li and K atoms with large atom numbers. The MOT simultaneously contains 5.2 × 10 Li-atoms and 8.0 × 10 K-atoms, which are continuously loaded by a Zeeman slower for Li and a 2D-MOT for K. The atom sources induce capture rates of 1.2 × 10 Li-atoms/s and 1.4 × 10 K-atoms/s. Trap l...

introduction: telomeric repeat amplification protocol assay (trap assay) is a standard established technique to detect the activity (expression) of telomerase in the cancerous samples. it includes a time-consuming procedure that has significant drawbacks such as high cost, complicacy, time-consuming procedure, equipment-dependent steps and false-positive signals caused by inclusion of pcr insid...

For the application of colloidal semiconductor quantum dots in optoelectronic devices, for example, solar cells and light-emitting diodes, it is crucial to understand and control their charge transport and recombination dynamics at high carrier densities. Both can be studied in ambipolar, light-emitting field-effect transistors (LEFETs). Here, we report the first quantum dot light-emitting tran...

Low frequency noise of current and light intensity of ultraviolet light emitting diodes LED with wavelength from 265 to 340 nm are the superposition of the 1/ f and generation-recombination noise. The dependence of generation-recombination noise on the LED current has a maximum caused by a relatively shallow trap level in the quantum well. The upper bound of this trap level concentration is est...
