We reanalyzed high quality spectra of 158 stars of spectral types A0–F1 and v sin i between 60 and 150 km s−1. Using a Least Squares Deconvolution technique we extracted high S/N broadening profiles and determined the loci of the Fourier transform zeros q1 and q2 where the S/N-ratio was high enough. The values of v sin i were redetermined and found to be consistent with the values derived by Ro...

In this paper we consider the processing of queries posed over multiple information resources that advertise their contents in terms of globally available, domain-specific ontologies. We describe a technique to identify the exact portion of a user’s query that may not be answered by the set of available information agents. This is achieved by reasoning over the advertisements of the agents rela...

The Chryseobacterium sp. kr6 strain has been described as a highly keratinolytic bacterium showing effective feather-degrading and de-hairing activities. A keratinase Q1 enzyme was purified from Chryseobacterium sp. kr6 culture by Phenyl Sepharose and Superose 12HR chromatography. This enzyme showed a specific activity of 967U/mg for keratin azure. Electrophoresis under denaturing conditions sh...

Let G = (V,E,Q) be a undirected graph, where V is the set of vertices, E is the set of edges, and Q = {Q1, . . . , Qq} is a partition of V into q subsets. We refer to Q1, . . . , Qq as the components of the partition. The Partition Coloring Problem (PCP) consists of finding a subset V ′ of V with exactly one vertex from each component Q1, . . . , Qq and such that the chromatic number of the gra...

RATIONALE Leukocyte telomere length (LTL) is a biological marker of aging, and shorter LTL is associated with adverse cardiovascular outcomes. Reduced regenerative capacity has been proposed as a mechanism. Bone marrow-derived circulating progenitor cells are involved in tissue repair and regeneration. OBJECTIVE Main objective of this study was to examine the relationship between LTL and prog...

BACKGROUND Factors contributing to chronic inflammation appear to be associated with increased risk of ovarian cancer. The purpose of this study was to assess the association between circulating levels of inflammation mediators and subsequent risk of ovarian cancer. METHODS We conducted a case-control study of 230 cases and 432 individually matched controls nested within three prospective coh...
