Centrality-dependent forward J/ψ production in high energy proton-nucleus collisions
2016
Forward $J/\psi$ production and suppression in high energy proton-nucleus collisions can be an important probe of gluon saturation. In an earlier work we studied this process in the Color Glass Condensate framework and showed that using the Glauber approach to extrapolate the dipole cross section of a proton to a nucleus leads to results closer to experimental data than previous calculations in this framework. Here we investigate the centrality dependence of the nuclear suppression in this model and show a comparison of our results with recent LHC data.
Forecasting the Cell Temperature of PV Modules with an Adaptive System
2013
The need to reduce energy consumptions and to optimize the processes of energy production has pushed the technology towards the implementation of hybrid systems for combined production of electric and thermal energy. In particular, recent researches look with interest at the installation of hybrid system PV/T. To improve the energy performance of these systems, it is necessary to know the operating temperature of the photovoltaic modules. Furthermore, when photovoltaic (PV) systems replace the traditional building envelope materials and they are fully integrated (building integrated photovoltaic (BIPV)), it is very important to correctly assess their thermal behaviour. The determination of …
Suppliers and Strategies for Upgrading in Global Production Networks: The Case of a Supplier to the Global Automotive Industry in a High-cost Location
2009
The paper analyses the possibilities for a Norwegian supplier incorporated into global production networks in the automotive industry to perform knowledge upgrading and innovation activity. A consistent finding is that different departments of the supplier are parts of different types of global network. The serial production of the supplier is distinguished by quasi-hierarchical governance by customers and by lean forms of work organization in the production that stimulate continuous, incremental upgrading of the production process. The development department has network relations with customers and learning forms of work organization, which triggers production and functional upgrading. The…
Etic and emic data production methods in the study of journalistic work practices: A systematic literature review
2021
This methodological paper discusses the application of etic and emic perspectives in producing data sets for the study of journalistic praxis. The concepts refer to the researcher-analyst’s and the practitioner-informant’s viewpoints, respectively, and that being the case, they have inherent weaknesses if used independently. We argue that these shortcomings can be mitigated through an integrated application of the concepts and by seeing the two perspectives as complementary to each other. Combining etic and emic perspectives will allow for a more comprehensive understanding of complex yet routinized real-life behaviour such as journalistic work. Following the appraisal of the etic-emic com…
Comparisons Of Labour Productivity And Per Capita Income In The Nordic Countries (2000-2010)
2013
Due to increased international trade for the last decades and also increased labour and capital mobility, there has been increased interest in international comparisons of economic performance and living standard among countries. Economic performance for a country may be measured by average labour productivity while living standard is measured by production per capita. Differences in these figures among countries are determined by differences in the number of working hours per person per year and the share of the population that works. This approach gives us the opportunity to examine how living standard and economic performance are related. Labour productivity depends, in general, on the a…
Content Production Strategies for E-Government
2008
The terms electronic government (e-government) and digital government are used to refer to the utilization of the Internet and other information and communication technologies (ICT) effectively in public sectors. In e-government development activities, the concern is often in building new means to support and strengthen democracy (e.g., Watson, Alselsen, Evjemo, & Aarsæther, 1999). In other cases, the main concern may be in supporting the work of people in public sectors (e.g., Mustajärvi, 2003), or in building new kinds of services for citizens (e.g., Lyytikäinen, Tiitinen, & Salminen, 2000). Common to most development activities is the need to have the content of public sector inf…
The Athena X-ray Integral Field Unit: a consolidated design for the system requirement review of the preliminary definition phase
2023
The Athena X-ray Integral Unit (X-IFU) is the high resolution X-ray spectrometer, studied since 2015 for flying in the mid-30s on the Athena space X-ray Observatory, a versatile observatory designed to address the Hot and Energetic Universe science theme, selected in November 2013 by the Survey Science Committee. Based on a large format array of Transition Edge Sensors (TES), it aims to provide spatially resolved X-ray spectroscopy, with a spectral resolution of 2.5 eV (up to 7 keV) over an hexagonal field of view of 5 arc minutes (equivalent diameter). The X-IFU entered its System Requirement Review (SRR) in June 2022, at about the same time when ESA called for an overall X-IFU redesign (i…
Sildenafil protects epithelial cell through the inhibition of xanthine oxidase and the impairment of ROS production
2009
Recent reports suggest that xanthine oxidase (XO), a modified form of the native xanthine dehydrogenase enzyme, plays an important role in various forms of ischemic and vascular injuries, inflammatory diseases, and chronic heart failure. The XO inhibitors allopurinol and its oxidation product oxypurinol held considerable promises in the treatment of these conditions both in experimental animals and in human clinical trials. More recently, an endothelium-based protective effect of sildenafil, a well-known type-5 phosphodiesterase inhibitor, has been reported in preconditioning prior to ischemia/reperfusion in healthy human subjects. Based on the structural similarities between allopurinol an…
Thermodynamic and Kinetic Modeling of Co-utilization of Glucose and Xylose for 2,3-BDO Production by Zymomonas mobilis
2021
Prior engineering of the ethanologen Zymomonas mobilis has enabled it to metabolize xylose and to produce 2,3-butanediol (2,3-BDO) as a dominant fermentation product. When co-fermenting with xylose, glucose is preferentially utilized, even though xylose metabolism generates ATP more efficiently during 2,3-BDO production on a BDO-mol basis. To gain a deeper understanding of Z. mobilis metabolism, we first estimated the kinetic parameters of the glucose facilitator protein of Z. mobilis by fitting a kinetic uptake model, which shows that the maximum transport capacity of glucose is seven times higher than that of xylose, and glucose is six times more affinitive to the transporter than xylose.…
