The main purpose of this paper is to detemine the fine spectrum of the generalized difference operator Delta_{uv} over the sequence space c0. These results are more general than the fine spectrum of the generalized difference operator Delta_{uv} of Srivastava and Kumar.

diesel exhaust particles are a complex mixture of thousands of gases and fine substances that contain more than 40 different environmental contaminants. being exposed to these exhaust particles (called soot) can cause lung damage and respiratory problems. diesel particulate filters are used in many countries for mobile sources as a legal obligation to decrease harmful effect of these fine parti...

in the industrial area of elefsis, greece, aerosol samples from the atmosphere were collected using a stacked filter unit sampler, which separates the airborne particulate matter into coarse (pm2.5-10) and fine (pm2.5) size fractions. the samples collected during the period january 2005 to march 2006, were analyzed by anodic stripping voltammetry (asv) and inductively coupled plasma atomic emis...

We catalog some simple conditions which are sufficient to guarantee that R-parity survives as an unbroken gauged discrete subgroup of the continuous gauge symmetry in certain supersymmetric extensions of the standard model. †Address after Sept. 1, 1992: Dept. of Physics, Northeastern University, Boston MA 02115 Low energy N = 1 supersymmetry has been proposed as a cure for the fine-tuning probl...

Despite extensive prior study, an understanding of the genetic organization of the maroon-like locus (ma-l:1-64n has been elusive. A large-scale, three-point fine structure recombination experiment is described, wholse results provide documentation for an inexcapable argument that maroon-like is a single element rather than a polycistronic system.

Three experiments, using a 2 (study context) x 2 (test context) between-subjects design, were conducted to examine the effects of environmental context manipulated by the combination of two contextual elements, place and task, on free recall. Undergraduates individually studied nouns and received a free-recall test, with a 10-minute filled retention interval. The contexts were manipulated by th...
