Simultaneous degradation of sulfadiazine, naproxen, diclofenac, ketoprofen and ibuprofen from drinking water was investigated by different technologies including photolysis, electrooxidation, photo-electrooxidation, zero-valent iron their combinations. All oxidation were very effective for the all drugs under anoxic conditions efficiency decreased oxic conditions. Results also revealed that can...

We propose a simple model in which an agent observes not only the choices made by others, but also some information about the process that led them to those choices. We consider two cases: In the first, an agent observes whether another agent has compared the alternatives before making his choice. In the second, an agent observes the time invested in deliberation before the other agent makes hi...

Zvi Miller and Nadav M. Shnerb Department of Physics, Bar-Ilan University, Ramat-Gan 52900, Israel Abstract The extinction transition in the presence of a localized quenched defect is studied numerically. When the bulk is at criticality, the correlation length diverges and even an infinite system cannot ”decouple” from the defect. The results presented here suggest that, in 1+1 dimensions, the ...

Laron syndrome (LS) is a rare, genetic disorder inherited in an autosomal recessive manner. The disease is caused by mutations of the growth hormone (GH) gene, leading to GH/insulin-like growth factor type 1 (IGF1) signalling pathway defect. Patients with LS have characteristic biochemical features, such as a high serum level of GH and low IGF1 concentration. Laron syndrome was first described ...

Yakimenko NSLS, BNL, Upton, NY 11973 Abstract The Photoinjected Energy Recovery Linac (PERL) design study at the NSLS is considering the feasibility of a new synchrotron light source based on a 3-7 GeV energy recovering superconducting linac initiated by a photoinjected RF gun [1]. To be a competitive light source the photoinj...

This paper utilizes unique survey data on labor union coverage at the firm level to examine union effects on the profitability of 705 U.S. companies during the 1970s. Market value and earnings are estimated to be about 10-15 percent lower in an average unionized company than in a nonunion company, following extensive control for firm and industry characteristics. Deleterious union effects on fi...
