ZnO nanorods with various lengths were synthesized by a two-stage route (by changing the time of growth between 0-240 min) and were characterized using XRD, SEM, UV–Vis and PL techniques. The SEM and XRD results confirmed a fast growth of (0 0 2) plane in the preferential longitudinal orientation, in contrast to lateral growth and therefore, by increasing the time of hydrothermal growth, nanoro...

background the treatment of onychomycosis is a challenge and infections are typically more severe and difficult to treat in toenails than in fingernails. objectives the current study aimed to investigate the fungicidal effect of ultraviolet radiation on the growth of dermatophytes isolated from nails. patients and methods samples from patients with clinical manifestations of onychomycosis were ...

the success rate of embryo production critically depends on several factors. one of the pivotal factors is a technique used for the whole procedure of in vitro fertilization (ivf) and in vitro embryo culture (ivc) (1, 2). besides the technique selected for ivf / in vitro embryo production (ivep), there is an important consideration called ivf/ivep culture dishes disinfection (3). for many years...

The treatment of bleach effluent from pulp and paper Industry for COD, colour and AOX removal was investigated using Ultra violet/Hydrogen peroxide process photocatalysed by Titanium dioxide. The Ultra violet / Titanium dioxide process was able to remove 48% and 37% of COD and colour. The Ultra violet / Hydrogen peroxide process was able to remove 52% and 59% of COD and colour. The combined pro...

In summarizing the results obtained for these 6 groups of animals, the following conclusions may be drawn: Normal rabbits living in total darkness and exposed to ultra-violet radiation at regular intervals showed a more rapid rate of increase in weight than animals living under the same condition, but after an initial period of rapid increase, the irradiated animals maintained a lower body weig...
