This dissertation describes a comprehensive study of the Zγ → eeγ/μμγ/νν̄γ process. The data have been collected with the DØ detector at the Fermilab Tevatron pp̄ collider with the center-of-mass energy of 1.96 TeV, and correspond to up to 3.6 fb−1 of integrated luminosity. Firstly, in this study we perform a measurement of the Zγ production cross section. The measured cross sections in both ``γ ...

This paper has two themes. In the first instance, we are concerned with uncovering the impact of intellectual thought on the practice of economic policy specifically, the influence of Keynesianism on fiscal policy. Keynes' idea that national governments can stabilize aggregate economic activity, presented in his General Theory of Employment, Interest and Money (1936), is one of the most importa...

No past studies of diarrhea in children of the Middle East have examined in detail the phenotypes of enterotoxigenic Escherichia coli (ETEC) strains, which are important pathogens in this setting. During a prospective study conducted from November 1993 to September 1995 with 242 children under 3 years of age with diarrhea living near Alexandria, Egypt, 125 episodes of diarrhea were positive for...

The study observes the size of Spanish State by analyzing composition public spending policies in Public Budget for years 2007-2012. government expenditure (central State, autonomous communities and local authorities) has not been reduced to level required achieve control debt. Furthermore, fiscal adjustment must be done without tax increases because they are harmful dynamic efficiency economy....

Context. Due to the sparsity and rapid evolution of high-mass stars, a detailed picture evolutionary sequence massive protostellar objects still remains be drawn. Some early phases their formation are so short that only select number throughout Milky Way currently find themselves spending time in those phases. Aims. Star-forming regions going through shortest stages star present different obser...

Unlike Shiga toxin 2 (stx(2)) genes, most nucleotide sequences of Shiga toxin 1 (stx(1)) genes from Shiga toxin-producing Escherichia coli (STEC), Shigella dysenteriae, and several bacteriophages (H19B, 933J, and H30) are highly conserved. Consequently, there has been little incentive to investigate variants of stx(1) among STEC isolates derived from human or animal sources. However stx(1OX3), ...
