The circadian biological clock is essentially based on the light/dark cycle. Some people working with shift schedules cannot adjust their sleep/wake cycle to the light/dark cycle, and this may result in alterations of the circadian biological clock. This study explored the circadian biological clock of shift and daytime nurses using non-invasive methods. Peripheral skin temperature, cortisol an...

In this work, we demonstrate controlled drug delivery from low-temperature-sensitive liposomes (LTSLs) mediated by photothermal heating from multibranched gold nanoantennas (MGNs) in triple-negative breast cancer (TNBC) cells in vitro. The unique geometry of MGNs enables the generation of mild hyperthermia (∼42 °C) by converting near-infrared light to heat and effectively delivering doxorubicin...

Eclosion rhythm parameters of D. ananassae strains originating between 8 degrees-34 degrees N were highly variable and latitude dependent. In the field under naturally fluctuating light intensity, temperature and R.H., the amplitude of the rhythm was high and the eclosion gate was narrow; however, under the naturally fluctuating light intensity but at constant temperature and R.H., the amplitud...

In this study we measured the degrees to which the Schottky barrier heights (SBHs) are lowered in ZnO nanowire (NW) devices under illumination with UV light. We measured the I-V characteristics of ZnO nanowire devices to confirm that ZnO is an n-type semiconductor and that the on/off ratio is approximately 10(4). From temperature-dependent I-V measurements we obtained a SBH of 0.661 eV for a Zn...

Our studies of thermally excited surface waves on liquids by means of light scattering, as described in earlier reports,l'2 have been extended to the problem of surface waves on the interface between two liquids. As a specific example, we have considered the methanol-hexane interface. A laser beam is scattered off the interface, and the light scattered in a certain direction is analyzed by mean...

This work analyzes the long-term functionality of HP (High-power) UV-LEDs (Ultraviolet Light Emitting Diodes) as the exciting light source in non-contact, continuous 24/7 real-time fluoro-sensing pollutant identification in inland water. Fluorescence is an effective alternative in the detection and identification of hydrocarbons. The HP UV-LEDs are more advantageous than classical light sources...

a series of ddt irritability tests with adult a. maculipennis typicus and a. superpictus were carried out in the isfahan area in august-september, 1970. the observations on irritability were measured in accordance with the who method arid the natural populations of anopheline mosquitoes were used. the tests were carried out in a light intensity of approximately 8 foot candles. the engorged mosq...
