Currently, vegetable oils have been studied as biolubricants Acrylic Keychain in order to reach new environmental standards.Besides being non-renewable, mineral oils from petroleum bring consequences to the environment due to its low biodegradability.Thus, the aim of this work is to develop a biolubricant and to add oxide nanoparticles (ZnO and CuO
AIM: To investigate the role of oxidative stress in regulating the functional expression of P-glycoprotein (P-gp) in mitochondria of D407 cells.METHODS: D407 cells were exposed to different ranges of concentrations of H2O2.The mitochondrial location of P-gp in the cells subjected to oxidative stress was detected by confocal analysis.Expression of P
Models of mass distribution in the Milky Way are discussed where those yielding the potential analytically are preferred.It is noted that there are three main contributors to the Milky Way potential: bulge, disc and dark halo.In the case of the disc the Miyamoto-Nagai formula, as simple enough, has shown as a very good solution, but it has not been
Assessment of disturbance can provide forest managers with information to make appropriate decisions on site rehabilitation and CHESTNUT BUD monitoring.This paper evaluates the accuracy of successive estimates of site disturbance using two ground survey methods.The results from the point transect and grid point transect and grid point intercept met
