Age-related cognitive differences may be due, in part, to difficulties using task-relevant context in a proactive manner. Two studies evaluated different methods for increasing older adults' use of context in the AX-Continuous Performance Task (H. E. Rosvold, A. F. Mirsky, I. Sarason, E. D. Bransome, & L. H. Beck, 1956), which evaluates components of context processing. The results suggest that...

this research, in addition to survey the existing data on the quality of sahebgharanieh wastewater treatment plant's effluent in the previous years, by runing a three months monitoring stage, studies the conditions of the final settling and aeration basin and the variations of the influent and effluent quantity and quality in removing of major pollutants (bod, cod, tss), while scrutinizing the ...

background escherichia coli (e. coli) species are able to produce extended-spectrum β-lactamases (esbls) that cause high resistance to the beta-lactam antibiotics. therefore, determining the antibiotic susceptibility patterns in resistant organisms is necessary for suitable therapeutic approaches. patients and methods totally, 260 clinical isolates of e. coli were collected from hospitals in te...

background & objectives:extended-spectrum-b-lactamase (esbl)-producing strains of klebsiella pneumoniaare an important cause of many serious infections in hospitalized and nonhospitalized patients and delayed treatment of these infections in crease chance of death in patients. this study was performed to determine the prevalence of esbl-producing k. pneumonia and to evaluate the frequency o...

nanofiltration-based separation processes have found diverse applications in industrial and environmentalproblems recently, due to several advantages such as lower energy requirement and elevated flux ratescompared with their reverse osmosis (ro) counterparts. several attempts have been made for modellingnf-based separation processes ranging from rigorous space-charge approaches to simpler irre...

Let X be a topological space and R be a subring of RX. By determining some special topologies on X associated with the subring R, characterizations of maximal fixxed and maximal growing ideals in R of the form Mx(R) are given. Moreover, the classes of zR-ideals and z0R-ideals are introduced in R which are topological generalizations of z-ideals and z0-ideals of C(X), respectively. Various c...

In this paper we further develop the theory of the extended Timoshenko beam model, as first introduced in Part I [5] of this work, with particular emphasis on applications of the model in formation theory [11], [12]. We begin with formal development of the equilibrium equations of static formation theory in the context of the extended Timoshenko model, giving a rigorous discussion of existence,...

We contribute to metadata management by giving a speciication of extended Entity-Relationship schemas with the extended Entity-Relationship model itself. We formulate a number of integrity constraints describing the context-sensitive requirements an extended Entity-Relationship schema has to ful-ll. By doing this, a certain class of schema queries can be formulated.
