In this study we evaluated the diffusion of nitrous oxide in a few operating rooms, using spatial data modelling techniques, in order to assess hospital staff exposure and to promote risk management. Indoor air sampling was carried out, during routine operating activity, by means of transportable infrared spectrometer, with geostatistical techniques. We detected high average concentrations of n...

The aluminum (Al) interlayer with various thicknesses ranging from 0.75 to 6 nm was deposited on silicon (Si) substrates prior to the deposition of ultra-thin iron (Fe) catalyst for the growth of carbon nanotubes. In this paper we report the effect of ultra-thin Al interlayer on the growth of multiwalled carbon nanotubes (MWCNTs). The SEM was used to examine the microstructures of nanotubes. We...

Peregrine Laziosi (1265-1345), an Italian priest, became the patron saint of cancer patients when the tumour in his left leg miraculously disappeared after he developed a fever. Elevated body temperature can cause tumours to regress and sensitizes cancer cells to agents that break DNA. Why hyperthermia blocks the repair of broken chromosomes by changing the way that the DNA damage checkpoint ki...

The current research aims to know the quantitative characteristics of groundwater and its spatial distribution in Tal Afar district. It was relied on a set data related groundwater. All them were entered into GIS environment for purpose performing digital manipulations drawing out maps. found that depth ranges between (0-519) m, stable level is within (0-89) variable (0-165) m. And amount decre...

Abstract The ZnO-BaO-B 2 O 3 -TeO (ZBBoT) glass samples were prepared, and their properties affected by varied concentrations of Nd doped in investigated. traditional melt quenching process was conducted to synthesize the which explored identify density, molar volume, refractive index, absorption, photoluminescence (PL) PL decay spectral profiles. optical absorption has been used derive Judd-Of...
