Time-resolved luminescence spectra of oriented PbWO(4) crystals have been measured for polarizations with the electric vector parallel to the crystallographic c axis (E is parallel to c) and perpendicular to it (E is perpendicular to c). All the three emission bands (I, II and III) due to the Jahn-Teller split states of a self-trapped exciton (STE) located on the (WO(4))(2-) complex anion are f...

forest roads are directions in natural habitats that used to transport wood products, secondary forest products and recreation. constructing forest roads causes trees clearing with specified width thus lead to direct or indirect changes in forest ecosystems and forest environment. this study aims to assess the changes of diversity and richness indices in main and secondary forest roads in a par...

The sand dunes and inter-dune zones of the hyper-arid central Namib Desert represent heterogeneous soil habitats. As little is known about their indigenous edaphic bacterial communities, we aimed to evaluate their diversity and factors of assembly and hypothesized that soil physicochemistry gradients would strongly shape dune/interdune communities. We sampled a total of 125 samples from 5 paral...

Joe Colletti, Steven Hoff, Janette Thompson and John Tyndall Iowa State University Abstract In Iowa at a commercial poultry facility, we are assessing the ability of a multi-row vegetative environmental buffer (VEB) to mitigate odor, ammonia, and particulates. In 2004 and 2005 Eastern redcedar (Juniperius virginiana), hybrid willow (Salix X) and limber pine (Pinus flexilis) were planted in rows...

If the fifth dimension is one-dimensional connected manifold, up to diffeomorphic, the only possible space-time will be M4 ×R1, M4 ×R/Z2, M4 × S1 and M4 ×S/Z2. And there exist two possibilities on cosmology constant: the cosmology constant is constant along the fifth dimension, and the cosmology constant is sectional constant along the fifth dimension. We construct the general models with paral...

PURPOSE The aim of this study was to assess the feasibility and advantages of a patient-specific breast bolus made using a 3D printer technique. METHODS We used the anthropomorphic female phantom with breast attachments, which volumes are 200, 300, 400, 500 and 650 cc. We simulated the treatment for a right breast patient using parallel opposed tangential fields. Treatment plans were used to ...

Abstract The fuel quality of hydrogen dispensed from 10 refuelling stations in Europe was assessed. Representative sampling conducted the nozzle by use a adapter allowing to bleed sample gas parallel while an FCEV. Samples were split off and distributed four laboratories for analysis accordance with ISO 14687 SAE J2719. results indicated some inconsistencies between but still conclusive. genera...

The objective of this study was to analyze the density and distribution of the bivalve Anomalocardia brasiliana in beaches in the estuarine region of the semiarid in Rio Grande do Norte State, Barra and Pernambuquinho (04°56.978'S and 37°08.961'W and 04°56.792'S and 37°09.375'W, respectively). Samples were collected monthly during 37 months using five transects (300 m long and 400 m apart) laid...

In this paper, the LogP model is used to analyze four parallel sorting algorithms (bitonic, column, radix, and sample sort). LogP characterizes the performance of modern parallel machines with a small set of parameters: the communication latency (L), overhead (o), bandwidth (g), and the number of processors (P ). We develop implementations of these algorithms in Split-C, a parallel extension to...
