Because wind is an intermittent power source, the variability may have significant impacts on system operation. Some studies have shown that this impact on regulation is not significant, but the impact on load following requirements has not yet received much attention. Part of the difficulty of analyzing the load following impact of wind is the inadequacy of most modeling frameworks to accurate...

An efficient transformation and expression system was developed for the industrially relevant basidiomycete Pycnoporus cinnabarinus. This was used to transform a laccase-deficient monokaryotic strain with the homologous lac1 laccase gene placed under the regulation of its own promoter or that of the SC3 hydrophobin gene or the glyceraldehyde-3-phosphate dehydrogenase (GPD) gene of Schizophyllum...

The errors in the first-guess (forecast field) of an analysis system vary from day to day, but, as in all current operational data assimilation systems, forecast error covariances are assumed to be constant in time in the NCEP operational three-dimensional variational analysis system (known as a spectral statistical interpolation or SSI). This study focuses on the impact of modifying the error ...

The ‘short rains’ in East Africa from October to December have significant year-to-year variability. Their abundance or deficiency is often associated with floods droughts for which early warning crucial, though even normal seasons skillful forecasts facilitate planning and preparedness. Here we study the relationship between initial-state sea surface temperatures subseasonal rainfall forecast ...

Despite the obvious desirability of formal testing procedures, earlier efforts at assessing the forecast accuracy of an estimated model revolved around the calculation of summary forecast error statistics e.g., see Klein (1991); Clements and Hendry (1993); Wallis (1995); Newbold, Harvey, and Leybourne (1999); and Stock and Watson (1999). Resort to such an informal approach may be ascribed mainl...

Two rat monoclonal antibodies (BRAC 1 and BRAC 11) have been produced. BRAC 1 recognizes an epitope common to the human erythrocyte membrane glycoproteins glycophorin C (GPC) and glycophorin D (GPD). BRAC 11 is specific for GPC. Fab fragments of these antibodies and BRIC 10, a murine monoclonal anti-GPC, were radioiodinated and used in quantitative binding assays to measure the number of GPC an...

Brown adipose tissue of the rat has been found to have an unusually high activity of mitohondrial alpha-glycerophosphate dehydrogenase (alpha-GPD) when assayed both by a histochemical staining procedure and by a quantitative biochemical method with isolated mitochondria. In contrast to succinic, glutamic, and beta-hydroxybutyrate dehydrogenases, all mitochondrial enzymes, the activity of alpha-...

The method of model fitting, or adjoint method, is applied to a barotropic hurricane track forecast model described by DeMaria and Jones using a large sample of forecast cases. The sample includes all Atlantic tropical cyclones that reached hurricane intensity during the 1989–93 hurricane seasons (141 72-h forecasts of 17 storms). The cases considered by DeMaria and Jones are a subset of the pr...

DNase I was used to probe the molecular organization of the chicken ovalbumin (OV) gene and glyceraldehyde 3-phosphate dehydrogenase (GPD) gene in interphase nuclei and in metaphase chromosomes of cultured chicken lymphoblastoid cells (MSB-1 line). The OV gene was not transcribed in this cell line, whereas the GPD gene was constitutively expressed. The GPD gene was more sensitive to DNase I dig...
