ABSTRACT In many problems in geostatistics we find that the response variable of interest is strongly related to the underlying geology of the spatial location. In(More)
To date, no direct measurements of primary production were taken in the Amundsen Sea, which is one of the highest primary productivity regions in the Antarctic. Phytoplankton carbon and nitrogen uptake experiments were conducted at 16 selected stations using a 13C–15N dual isotope tracer technique. We found no statistically significant depletions of major(More)
OBJECTIVE The primary aim of this study was to investigate the acute impact of methylphenidate (MPH) on sleep parameters in attention-deficit/hyperactivity disorder (ADHD) children. The second aim was to investigate the different effects of intermediate- and longacting MPH on sleep parameters. The third aim was to test the different effects of dose and age(More)
Ba sed on biophysical ice-core data collected in the landfast ice off Barrow, Alaska, USA, in 2002 and 2003, a one-dimensional ice–ocean ecosystem model was developed to determine the factors controlling the bottom-ice algal community. The data and model results revealed a three-stage ice-algal bloom: (1) onset and early slow growth stage before mid-March,(More)
BACKGROUND/AIMS The reappearance rates of hepatitis C virus (HCV) RNA after a sustained virological response (SVR) have been reported to be 1-2%. We investigated the reappearance rate of HCV RNA after SVR in chronic hepatitis C (CHC) patients treated with pegylated interferon (PEG-IFN) and ribavirin. METHODS In total, 292 CHC patients who achieved an SVR(More)
Since the vessels are getting larger and the efficiency of container terminals is more required, highly automated container terminals are being developed and operated. The ECT in Netherlands and the CTA in Germany-fully automated container terminal (ACT) – have improved productivity through automated yard and transportation areas. But after building these(More)
