zno nps (zinc oxide nanoparticles) has generated significant scientific interest as a novel antibacterial and anticancer agent. since oxidative stress is a critical determinant of zno nps-induced damage, it is necessary to characterize their underlying mode of action. different structural and physicochemical properties of zno nps such as particle surface, size, shape, crystal structure, chemica...

Prism elements arise in some printed circuit board modeling contexts, such as visualization and electromagnetic field modeling. Here we consider prisms built by extruding from triangular bases which result from constrained 2d Delaunay triangulation. The goal is to partition each extruded prism into sub-prisms of high quality that fit within the given printed circuit board layers. A prism qualit...

purpose: to present a case of spontaneous resolution of essential esotropia case report: a 22-month-old girl presented with eye deviation since the age of 4 month. in the first examination, visual acuity of both eyes was c+s+m+. the patient had 35 prism diopters of alternative esotropia in primary position and also bilateral inferior oblique overaction (iooa). there was no significant refractiv...

in this study the effect of nitric oxide synthesis inhibition on stress-induced gastric damage was evaluated in bile duel ligated, sham operated and unoperated rats. animals were injected intraperitoneally with ng-nitro-l-arginine methylester (l-name), 40 mglkg, l-argininc, 200 mg/kg or saline, 30 min before water-immersion stress. one hour after water immersion, the animals were killed and the...

The surface stress induced during the formation of alkanethiol self-assembled monolayers (SAMs) on gold from the vapor phase was measured using a micromechanical cantilever-based chemical sensor. Simultaneous in situ thickness measurements were carried out using ellipsometry. Ex situ scanning tunneling microscopy was performed in air to ascertain the final monolayer structure. The evolution of ...

Geographers have long been interested in spatio-temporal patterns of human activity, and in the consequences of these patterns on urban development and transportation networks. Typically, data about individuals’ behaviour in space and time has been collected using activity-travel diaries. Today, automatic tracking by GPS receivers gains importance, e.g. in real-time fleet management, and people...

conclusions regular consumption of various fresh fruits and vegetables, whole grains, legumes and beans, sprouts and seeds is an effective and safe way to meet all antioxidant requirements in physically active persons and athletes. results it seems that the best recommendations regarding antioxidants and exercise are having a balanced diet rich in natural antioxidants and phytochemicals. eviden...

Under the effect of surface tension, a blob of liquid adopts a spherical shape when immersed in another fluid. We demonstrate experimentally that soft, centimeter-size elastic solids can exhibit a similar behavior: when immersed into a liquid, a gel having a low elastic modulus undergoes large, reversible deformations. We analyze three fundamental types of deformations of a slender elastic soli...

Maps of interpolated climate normals have recently become essential tools for many types of forestry research, such as studying genetic adaptation of trees to local environments, modeling species ranges shifts, or forest productivity under climate change scenarios. In this paper, we evaluate two widely used climate models for British Columbia with respect to their general precision and regional...
