"Table 3" of "Studies of W boson plus jets production in p\bar{p} collisions at sqrt(s)=1.96 TeV"
2013
Differential production cross-section, normalized to the measured inclusive W boson cross-section, as a function of third jet rapidity for events with three or more jets produced in association with a W boson. First uncertainty is statistical, second uncertainty is systematic.

Thermal characterisation of Bio Based Building Materials
2006
This paper describes how the characterization of indigenous renewable biomass sources that are applicable for making bio-based building (BBB) materials is crucial as it can significantly affect the cost of production and the quality of material. Nowadays, in any specific area, wide ranges of biomass sources are usually available but only a few sources may be suitable for making BBB material. Therefore the suited sources should be determined. In this paper, the use of BBB materials is focused on Insulation Materials which are widely used in the buildings. Compared with currently used materials, these materials are bio-degradable. Insulation material with a good energy-adsorbing property and …
Coadsorption of NRR and HER Intermediates Determines the Performance of Ru-N4 toward Electrocatalytic N2 Reduction
2021
Efficiency of the electrochemical N2 reduction reaction (NRR) to ammonia is seriously limited by the competing hydrogen evolution reaction (HER) but our current atomic-scale insight on the factors controlling HER/NRR competition are unknown. Herein we unveil the elementary mechanism, thermodynamics, and kinetics determining the HER/NRR selectivity on the state-of-the-art NRR electrocatalyst, Ru-N4 using constant potential density functional theory calculations (DFT). The calculations show that NRR and HER intermediates coadsorb on the catalyst where HER is greatly suppressed by the NRR intermediates. The first reaction step leading to either *NNH or *H determines the selectivity towards NRR…
Is Written Language Production more Difficult than Oral Language Production? A Working Memory Approach
1994
Abstract Is written language production more difficult than oral language production? Probably, yes. But why? Several experiments were conducted in order to test the impact of low-level activities involved in writing on the performance of higher-level activities also involved in writing. Three assumptions were made: (1) the capacity of working-memory is limited, (2) every component of writing has a cognitive load, and (3) every increase in the load devoted to the activity of one component would lead to a decrease in the remaining resources available for the other components. These low-level activities are more resource-consuming in children than in adults because children have not yet autom…
Capital humain et compétences de base des adultes : production et valorisation
2013
Basic skills are important in current policies because of high costs generated by illiteracy and supported by the society. The aim of the present thesis is to bring a new contribution on this thematic in a microeconomic approach. It consists of two parts. The first one concerns the valorization of basic skills on the labor market, through chapters 1 and 2, while the second one concerns the production of French skills according to the migratory origins, through chapters 3 and 4. Chapter 1 is about the returns to basic skills on the labor market, in terms of overeducation/undereducation and in terms of wages. The central hypothesis is to assume that education, through the diploma, is not a go…
Translocation of Zymomonas mobilis pyruvate decarboxylase to periplasmic compartment for production of acetaldehyde outside the cytosol
2019
Abstract Acetaldehyde, a valuable commodity chemical, is a volatile inhibitory byproduct of aerobic fermentation in Zymomonas mobilis and in several other microorganisms. Attempting to improve acetaldehyde production by minimizing its contact with the cell interior and facilitating its removal from the culture, we engineered a Z. mobilis strain with acetaldehyde synthesis reaction localized in periplasm. For that, the pyruvate decarboxylase (PDC) was transferred from the cell interior to the periplasmic compartment. This was achieved by the construction of a Z. mobilis Zm6 PDC‐deficient mutant, fusion of PDC with the periplasmic signal sequence of Z. mobilis gluconolactonase, and the follow…
La «innovación escondida» de las pymes industriales en el capitalismo español. Gestión, estrategias y repertorios de prácticas innovadoras en pymes m…
2019
Las pymes industriales dinámicas e innovadoras son una de las bases de prosperidad colectiva en algunos países y regiones europeas. Desde una sociología multinivel que integra los niveles micro (empresarial-organizativo), meso (regional-local y sectorial) y macro (capitalismo estatal-nacional) dentro del sistema de redes-cadenas de producción del capitalismo global, el artículo analiza la actividad innovadora de las pymes industriales, la cual se puede denominar innovación escondida al no aparecer en los indicadores convencionales de innovación. En base a 22 entrevistas semiestructuradas a directivos de pymes manufactureras de Cataluña, se aplica la Teoría Fundamentada para construir catego…
Exergy recovery during LNG regasification: Electric energy production – Part one
2009
Abstract In liquefied natural gas (LNG) regasification facilities, for exergy recovery during regasification, an option could be the production of electric energy recovering the energy available as cold. In a previous paper, the authors propose an innovative process which uses a cryogenic stream of LNG during regasification as a cold source in an improved combined heat and power (CHP) plant. Considering the LNG regasification projects in progress all over the World, an appropriate design option could be based on a modular unit having a mean regasification capacity of 2 × 109 standard cubic meters/year. This paper deals with the results of feasibility studies, developed by the authors at DRE…
