The alpha and gamma phases of aluminum oxide were fingerprinted using electron energy-loss spectroscopy (EELS) with an energy resolution of 0.4 eV. Electron diffraction and powder x-ray diffraction were used to determine the phase of micron and nanopowder alumina samples. The results from indexing peak and ring diffraction patterns proved to be ambiguous and were resolved by comparing EELS spec...

An American geographer specializing in southeast Europe and the Middle East examines Turkey’s prospects for membership in the European Union, a process that recently received a positive recommendation by the European Commission. Of particular importance in the debate over Turkish accession are claims that cultural differences divide Europe and Turkey, and overshadow both their shared history an...

1. The binding of prostaglandin A2 and prostaglandin F2, to human plasma proteins was investigated by DEAE-Sephadex chromatography and polyacrylamide-gel electrophoresis. Both prostaglandins, when added to human plasma in vitro, were found to become bound mainly to plasma albumin. 2. The extent of binding of prostaglandins added to human plasma in low to moderate concentrations was found to be ...

In the search for heterologous activators for actinorhodin production in Streptomyces lividans, 3.4 kb of DNA from Streptomyces rochei F20 (a streptothricin producer) were characterized. Subcloning experiments showed that the minimal DNA fragment required for activation was 0.4 kb in size. The activation is mediated by increasing the levels of transcription of the actII-ORF4 gene. Sequencing of...

BACKGROUND This investigation was designed to characterize psychotic disorders among patients originally treated as in- and outpatients by child and adolescent psychiatric services and subsequently followed-up into mid-adulthood. The age at the first onset on symptoms, possible changes in diagnoses, early signs noted prior to or upon admission to child and adolescent psychiatric care and possib...

According to the pollution haven effect (PHE) mobile capital responds to environmental regulation by moving from countries with high regulation to those with low regulation. Previous tests of the PHE have focused on host country regulation effect. This study also examines the effect of home country regulation on foreign direct investment (FDI). I use a panel of 28 OECD countries for 1981-2000 t...

Transportation costs are of central importance in the New Economic Geography literature, though assumptions about transportation costs continue to be simplistic. This paper begins to address these simplifications by assuming that transportation costs for manufactured goods are heterogeneous. Basic results are consistent with standard models showing dispersion of economic activity for high trans...

A new simultaneous autofocus and two-fold astigmatism correction method is proposed for High Angle Annular Dark Field Scanning Transmission Electron Microscopy (HAADF-STEM). The method makes use of a modification of an image variance, which has already been used before as an image quality measure for different types of microscopy. In this paper we describe numerical simulations based on a class...

Phage-displayed alanine shotgun scanning was used to dissect contributions by engrailed homedomain (En-HD) residues 17 through 46, which indirectly influence recognition of DNA. The relative contributions of such indirect contacts, quantified by shotgun scanning, highlight previously unexplored En-HD residues. Two motifs dominate En-HD function in this region. First, two surface-exposed aromati...
