Light-responsive artificial ion channels are created using self-organized TiO(2) nanotubular arrays, whose ion transport properties can be regulated by external ultraviolet light. The formation of electrostatic traps within TiO(2) nanotubes by UV light contributes to the light-regulated ion transport.

We conducted two experiments to determine the best CDC-trap configuration for catching male and female Phlebotomus papatasi. First, visual features were evaluated. Standard CDC traps were modified to have black or white catch bags, black or white lids, or no lids and these were tried in different combinations. Significantly more male sand flies were caught by darker traps; significantly more fe...

eucalyptus species are cultivated in homogeneous plantations in brazil, mainly to supply woodfor the cellulose and steel industries, which favors the establishment of insect pests. the objective was todetermine the geographical distribution and structure abundance of lepidoptera defoliators of eucalypt.primary pest species of eucalypt of the order lepidoptera were found in all areas sampled and...

Malaria infection is a serious public health problem throughout Liberia, but vector surveillance is limited or nonexistent in remote regions of the country. To better understand the spatial and temporal distribution of malaria vectors in Liberia and to support vector and malaria activities of the Liberian Ministry of Health, a study was conducted to determine the efficacy of light traps baited ...

OBJECTIVE The western borderland between Yunnan Province, China, and Myanmar is characterized by a climate that facilitates year-round production of mosquitoes. Numerous mosquito-transmitted viruses, including Japanese encephalitis virus circulate in this area. This project was to describe seasonal patterns in mosquito species abundance and arbovirus activity in the mosquito populations. METH...

background: wearing spectacles is the most common approach in correcting the refractive errors worldwide. due to harmful effects of overexposure to solar ultraviolet radiations, the usage of multi-layer coatings in ophthalmic lenses has recently been increased. these lenses can reduce the reflections and hence increase the transmission of visible light; they can also decrease the transmission o...

Ultrafast time-resolved photoluminescence spectroscopy following oneand two-photon excitation of ZnO powder is used to gain unprecedented insight into the surprisingly high external quantum efficiency of its “green” defect emission band. The role of exciton diffusion, the effects of reabsorption, and the spatial distributions of radiative and nonradiative traps are comparatively elucidated for ...
