There is a vast quantity of information available in unstructured form, and the academic and scientific communities are increasingly looking into new techniques for extracting key elements finding the structure in the unstructured. There are various ways to identify and extract this type of data; one leading system, which we will focus on, is the UIMA framework. Tasks that are often desirable t...

A membrane electrode assembly (MEA) for hydrogen fuel cells has been fabricated using single-walled carbon nanotubes (SWCNTs) support and platinum catalyst. Films of SWCNTs and commercial platinum (Pt) black were sequentially cast on a carbon fiber electrode (CFE) using a simple electrophoretic deposition procedure. Scanning electron microscopy and Raman spectroscopy showed that the nanotubes a...

The accurate recognition of individuals is a cornerstone of social exchange in primates. Current approaches to the study of individual recognition, however, are focused on human performance and only occasionally reference comparative research for support. A number of studies have suggested that humans can easily recognize thousands of individual faces and that this perceptual expertise is suppo...

Nucleotide sequence analysis of the env gene of two different endogenous feline leukemia virus (FeLV) loci, CFE-6 and CFE-16, of domestic cats revealed the following characteristics. (i) Both proviruses contain an open reading frame in the env region; (ii) whereas the full complement of the exogenous FeLV env is generally present in CFE-6 DNA, it is truncated in CFE-16 DNA such that the 5' half...

A characterization of nitrocompounds activation by cell-free extracts (CFE) of wild-type (AB(+)), SnrA deficient (B(+)), Cnr deficient (A(+)) and SnrA/Cnr deficient (AB(-)) Salmonella typhimurium strains has been done. The Ames mutagenicity test (S. typhimurium his(+) reversion assay) was used, as well as nitroreductase (NR) activity determinations where the decrease in absorbance generated by ...

AIM To evaluate the use of human serum (HS) in supporting the in vitro and in vivo proliferation of human conjunctival epithelial cells, and compare it with fetal bovine serum (FBS) and bovine pituitary extract (BPE). METHODS Conjunctival epithelial cells were cultivated in media supplemented with HS (5%, 10%), FBS (5%, 10%), and BPE (70 microg/ml, 140 microg/ml). The colony forming efficienc...

Modifications to the colony assay in vitro for stromal progenitor cells in mouse femoral marrow have been studied so as to optimize the efficiency of colony formation (CFE). The highest reproducible concentration achieved was about 30 colonies (containing fibroblasts, macrophages and endothelioid cells) per 10(6) nucleated marrow cells (range 20-50) in mice 3-4 months old, and higher by 50% in ...

Scotland’s Curriculum for Excellence (CfE) is a good example of a new breed of national curriculum; a curricular model that seeks to combine top-down government prescription with bottom-up school-based curriculum development by teaching professionals. However, in developing a renewed view of teachers as agents of change and relaxing curriculum prescription, CfE has attracted criticism for its v...

We present a simple approach to calculate the thermodynamic properties of single Kondo impurities including orbital degeneracy and crystal field effects (CFE) by extending a previous proposal by Schotte and Schotte (1975 Phys. Lett. 55A 38). Comparison with exact solutions for the specific heat of a quartet ground state split into two doublets shows deviations below 10% in the absence of CFE an...
