ORJECI1VE: To evaluate the effect of copper-silver ionization on Legionella colonization and nosocomial legionnaires' disease and to compare the efficacy of metal ions versus the superheat-and-tlush method of disinfection. DESIGN: Prospective determination over a 36-month period of copper and silver ion concentrations in the recirculating hotwater system, Legionella colonization of the hospital...

the main idea of this paper is to study the dependence between the probability of default and the recovery rate on credit portfolio and to seek empirically this relationship. we examine the dependence between pd and rr by theoretical approach. for the empirically methodology, we use the bootstrapped quantile regression and the simultaneous quantile regression. these methods allow to determinate...

The need for treatment of dilute metal contaminated water as a residual from mining and mineral processing facilities is ubiquitous. Electrochemical technologies have the potential to provide selective and measurable recovery of base metals from dilute mining influenced water. However, the technology is currently not widely used in the treatment of mining influenced water (MIW). The principles ...

conclusions the sex differences in the neuroanatomy of the human mirror neuron system affect functional recovery of patients with hemiparesis. the improvement in studied women was found to be significantly greater than studied men. the results indicate a higher chance of recovery among hemiparetic women, especially those watching functional movies. results comparison of all variables related to...

Copper and iron may be sequentially measured in a single aliquot of a protein-free filtrate by use of bis(1 -piperidylthiocarbonyl) disulfide and disodium 3(2pyridyl) -5,6-bis(4-phenylsulfonic acid) -1, 2,4-triazine (also known as ferrozine). Recovery studies showed excellent results for both metals in various concentrations. Copper interference has been obviated by use of thiourea in mercaptoa...
