Length of growing-season data wete obtained from 90 weather stations covering the core of the U.S. Corn Belt from 1911-2000 and analyzed qualitatively and statistically to ascertain if any systematic trends in warming were/are occurring within
the context of global warming. The AA. found that the 1920s were statistically cooler and the 1990s warmer. No discernible trend was statistically found throughout the 90-year-period.

This paper examines the effects of record length on the precision of turbulence statistics in fluvial boundary layers of gravel-bed rivers. From high-resolution velocity time series lasting 20 to 60 min, a bootstrapping method is used to determine
optimal record lengths and standard errors for 10 commonly used turbulence statistics.

The report is an attempt to estimate the agricultural production value in Slovenia on the basis of estimation districts and geographical regions. The report is based on data of harvest and production, collected by Statistical Office of Slovenia
within the census of agricultural farming in the year 2000, and on the average purchase price for some agricultural products, which are registered in the department of agricultural statistics at the Statistical Office in the year 2003. The results should
