Olot, Barcelona and Avila and the introduction of the Arkwright technology to Catalonia
Get PDFEditada en la Fundación SEPIEste articulo muestra los medios a través de los cuales la industria algodonera
catalana logró independizarse de las importaciones de hilo en una
etapa crítica de su desarrollo entre 1790 y la Guerra de la Independencia.
Ello fue posible gracias a la temprana difuisión de la tecnología Arkwright,
a lo cual contribuyeron hombres de negocios de Olot, Barcelona y Ávila vinculados
a distintas ramas manufactureras. El artículo también muestra el carácter
de la industria productora de maquinaria textil y los intentos realizados para
limitar la difusión de la nueva tecnología.This article clarifies the means whereby the Catalán cotton índustry
attained independence from imported yarn in a critical stage of its development
between the 1790s and the War of Independence. It does so by tracking the
origins, and early diffusion, of the Arkwright technology in Catalonia in the
form of a machine-making and spinning company formed between an Olotí
stocking frame knitter, a Barcelona silver-smith and an Ávila trained machinemaker.
The spinning and weaving initiatives of the Company inform on the circunstances conditioning the Catalán industry's incorporation of the spinning
processes. Light is also thrown on the character of machine-making at
this stage of Catalán industrialízation in a pilot-entetpríse anxious to restríct
technical díffusion.Publicad
A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
Extracting Boer-Mulders functions from p+D Drell-Yan processes
No full textWe extract the Boer- Mulders functions of valence and sea quarks in the proton from unpolarized p + D Drell- Yan data measured by the FNAL E866 Collaboration. Using these Boer- Mulders functions, we calculate the cos2 phi asymmetries in unpolarized pp Drell- Yan processes, both for the FNAL E866/ NuSea and the BNL Relativistic Heavy Ion Collider experiments. We also estimate the cos2 phi asymmetries in the unpolarized p (P) over bar Drell- Yan processes at GSI.Astronomy & AstrophysicsPhysics, Particles & FieldsSCI(E)37ARTICLE5null7

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
Get PDFBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Measurement of the D+/- production asymmetry in 7 TeV pp collisions
Get PDFThe asymmetry in the production cross-section \sigma of D+/- mesons, A_P = (\sigma(D+) - \sigma(D-))/(\sigma(D+) + \sigma(D-)), is measured in bins of pseudorapidity \eta and transverse momentum p_T within the acceptance of the LHCb detector. The result is obtained with a sample of D+ -> K_S pi+ decays corresponding to an integrated luminosity of 1.0 fb^-1, collected in pp collisions at a centre of mass energy of 7 TeV at the Large Hadron Collider. When integrated over the kinematic range 2.0 K_S pi+ decay is negligible. No significant dependence on \eta or p_T is observed
