We test the correlation found by Reichart et al. (2001) between time variability and peak luminosity of Gamma-Ray Bursts (GRBs). Recently Guidorzi et al. (2005) found that this still holds for a sample of 32 GRBs with spectroscopic redshift, although with a larger scatter than that originally found by Reichart et al. (2001). However Guidorzi et al. (2005) also found that a power law does not pr...

Pesticide contamination of river and lake waters from agriculture use is a problem of worldwide importance. Many field data on the pesticide contamination of surface waters and aquatic organisms in rivers and lakes (Amaraneri & Pillala, 2001, Abdel-Halim et al., 2006; Agradi et al., 2000; California Environmental Protection Agency, 2002; California Regional Water Quality Control Board, 2002; Ca...

GTP hydrolysis, for the translocation of the mRNA chain and the tRNA molecules. Analysis of the three-dimensional structures of unbound ribosomal subunits from eubacteria (Figure 1A; Schluenzen et al., 2000; Wimberly et al., 2000; Harms et al., 2001) and archaea (Ban et al., 2000) as well as of the entire ribosome (Yusupov et al., 2001) clearly showed that the centers of the major ribosomal act...

—The effect of feeding three commercial diets on production characteristics and body composition of juvenile cobia Rachycentron canadum reared using recirculating aquaculture systems (RASs) was assessed in a 56-d growth trial. Juvenile cobia (mean weight 6 SE, 29.2 6 0.7 g) were stocked into three 8-m tanks in each of four RASs at an initial density of 1.2 kg/m. After stocking, fish were fed on...

decisions in healthcare should be based on information obtained according to the principles of evidence-based medicine (ebm). an increasing number of systematic reviews are published which summarize the results of prevalence studies. interpretation of the results of these reviews should be accompanied by an appraisal of the methodological quality of the included data and studies. the critical a...

Stomatal closure in response to the hormone abscisic acid (ABA) is mediated by a complex signaling network involving both calcium-dependent and calciumindependent pathways (Assmann and Shimazaki, 1999; Webb et al., 2001), activated by several signaling intermediates (Schroeder et al., 2001) that include hydrogen peroxide (Miao et al., 2000; Pei et al., 2000; Zhang et al., 2001) and lipids such ...
