We analyse the impact of regulation, industrial policy and jurisdictional allocation on broadband deployment using a theoretical model and an empirical estimation. Although central powers may be more focused and internalize interjurisdictional externalities, decentralized powers may internalize local horizontal policy spillovers and use a diversity of objectives as a commitment device in the pr...

and t6 are the isospin raising and lowering single-particle operators. Two main proposals were made to explain this puzzling quenching of the GT strength; ~1! the missing strength is removed to the very high excitation energy of about 300 MeV above the ground state due to the process in which a nucleon is transformed into a D33 resonance, or more precisely the GT strength is removed due to the ...

Centralized wage-setting institutions compress relative wages. Motivated by this fact, we investigate the effects of centralized wage setting on the industry distribution of em-ployment. We examine Sweden’s industry distribution from 1960 to 1994 and compare it to the U.S. distribution over the same period. We relate U.S.-Swedish differences in the industry distribution and their evolution over...

The Hartree–Fock self-consistent-field approximation has provided an invaluable conceptual framework and a standard computational procedure for atomic and molecular quantum theory. Its shortcomings are significant however, and require remediation. Mo”ller–Plesset perturbation theory offers a popular correction strategy: it formally expands eigenfunctions and eigenvalues as power series in a cou...

It is well established that increasing mesh number in the circumference of a diamond-mesh trawl codend can reduce size selection for round fish, whereas selection for flat fish species is unaffected. This effect has also been documented in Mediterranean trawl fisheries. In contrast, no information is available with regard to the effect of increasing mesh number in the circumference of square-me...

One of the most important sources of noise pollution in urban areas is traffic noise. The aim of the present study was to determine noise pollution in the different parts of Yazd city in 2010 and to compare them with current standard levels. In total, 135 samples were obtained from both residential and commercial areas according to the ISO 1996-2002 method in order to measure noise pressure lev...

RNA binding properties of proteins from the large subunit of bovine mitochondrial ribosomes were studied using four different approaches: binding of radiolabeled RNA to western blotted proteins; disassembly of the intact 39 S ribosomal subunits with urea; binding of ribosomal proteins to RNA in the presence of urea; and binding of proteins extracted with lithium chloride to RNA. Results from th...

Production of bacteriocins is a potential probiotic feature of many lactic acid bacteria (LAB) as it can help prevent the growth of pathogens in gut environments. However, knowledge on bacteriocin producers in situ and their function in the gut of healthy animals is still limited. In this study, we investigated five bacteriocin-producing strains of LAB and their isogenic non-producing mutants f...

C sapidus fisheries has a significant influence on the economy of some countries in North America and has a relative extensive literature in these regions. However, only few papers discuss the ecology of C. sapidus in the South Atlantic, despite its economic importance in that region. We studied the fecundity, reproductive seasonality and maturation size of C. sapidus females captured in the So...

Bread wheat (Triticum aestivum L.) is the most important staple food crop for 35% of the world's population. International efforts are underway to facilitate an increase in wheat production, of which the International Wheat Genome Sequencing Consortium (IWGSC) plays an important role. As part of this effort, we have developed a sequence-based physical map of wheat chromosome 6A using whole-geno...
