Single-stranded regions in RNA secondary structure are important for RNA-RNA and RNA-protein interactions. We present a probability profile approach for the prediction of these regions based on a statistical algorithm for sampling RNA secondary structures. For the prediction of phylogenetically-determined single-stranded regions in secondary structures of representative RNA sequences, the proba...

In recent years, the poultry industry has seen a steady growth in Iowa. With the increase in the broiler and egg industry, the public is concerned about the potential threat to environmental quality (surface and subsurface water and air quality) from increased volumes of poultry manure. Although the effect of poultry manure on crop production has been studied, its effects on water quality, unde...

Motivated by observations of the subglacial drainage of water, we consider a hydraulic fracture problem in which the crack grows parallel to a free surface, subject to fully turbulent fluid flow. Using a hybrid Chebyshev=series-minimization numerical approach, we solve for the pressure profile, crack opening displacement, and crack growth rate for a crack that begins relatively short but eventu...

The degradation behavior of cefquinome sulphate in alkaline medium at different temperatures was investigated using both first derivative spectrophotometric and HPLC methods. The drug degradation was found to be pH and temperature dependant. The pH-rate profile indicated a first order dependence of Kobs on [OH(-)] at pHs ranging between 9 and 11. Arrhenius plot obtained at pH 10 was linear betw...

SAS/GRAPH is a powerful tool for customizing the box plot to detect and identify outliers. This paper shows how to use the ANNOTATE facility and annotate data set to customize box plots and profile plots of outliers using data from a dietary-health study. This paper assumes: • A working knowledge of basic SAS/GRAPH procedures. • The ability to display or print graphics on your operating system...

Climate-induced changes in regional precipitation could have important implications for the carbon, water, and nutrient cycles of forest ecosystems. However, few studies have examined the response of deciduous forests to increases or decreases in precipitation. Therefore, the throughfall displacement experiment (TDE) was established in 1993 near Oak Ridge, Tennessee to examine the sensitivity o...

The addition of exogenous fibrolytic enzymes (EFEs) and length storage can affect the quality maize silage. Therefore, objective this study was to evaluate fermentative profile nutritive value silage treated with different doses EFEs ensiled for 30, 60, or 90 days. designed as completely randomized in a split-plot arrangement treatments, where four were assigned main plot three lengths sub-plot...
