LIFE CYCLE ASSESSMENT EXPERIENCES FOR SOLAR HEATING AND COOLING SYSTEMS

2018

Solar heating and cooling systems can significantly contribute to the energy and climate European goals. A complete assessment of this contribution needs the analysis of these systems from a life-cycle perspective, in order to estimate the energy and environmental costs of their manufacturing and end-of-life, and to compare these costs with the benefits obtained during operation. A well-established methodology to fulfil this task is the Life Cycle Assessment (LCA). The paper describes some LCA experiences of solar heating and cooling systems, developed within the Task 53 “New generation solar cooling & heating systems (PV or solar thermally driven systems)” of the International Energy A…

On-Orbit Degradation of Solar Instruments

2013

International audience; We present the lessons learned about the degradation observed in several space solar missions, based on contributions at the Workshop about On-Orbit Degradation of Solar and Space Weather Instruments that took place at the Solar Terrestrial Centre of Excellence (Royal Observatory of Belgium) in Brussels on 3 May 2012. The aim of this workshop was to open discussions related to the degradation observed in Sun-observing instruments exposed to the effects of the space environment. This article summarizes the various lessons learned and offers recommendations to reduce or correct expected degradation with the goal of increasing the useful lifespan of future and ongoing s…

Shell-model computed cross sections for charged-current scattering of astrophysical neutrinos off 40Ar

2018

Charged-current (anti)neutrino-$^{40}\mathrm{Ar}$ cross sections for astrophysical neutrinos have been calculated. The initial and final nuclear states were calculated using the nuclear shell model. The folded solar-neutrino scattering cross section was found to be $1.78(23)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}42}\phantom{\rule{4pt}{0ex}}{\mathrm{cm}}^{2}$, which is higher than what the previous papers have reported. The contributions from the ${1}^{\ensuremath{-}}$ and ${2}^{\ensuremath{-}}$ multipoles were found to be significant at supernova-neutrino energies, confirming the random-phase approximation (RPA) result of a previous study. The effects of neutrino flavor conve…

Cheap sensor made of multicrystalline silicon for insolation and temperature measurements

2016

In the paper some results on measurement of insolation and „real” cell’s temperature carried out with use of standard silicon solar cells are presented. Two identical cells are applied in such a sensor. Short circuit current of one cell is a direct indication of insolation value and open circuit voltage of the other cell is indirect indication of actual sensor’s temperature but in this case more complex formula must be used for temperature calculation.

Characterization of Ruthenium-based Dye-Sensitized solar cells

2015

In this paper, we measure the main photoelectrical parameters of Dye Sensitized Solar Cells (DSSCs) based on ruthenium complexes at different irradiance levels, incident wavelengths, temperatures and hours of light soaking.

I soldati nelle città: osservazioni sul lessico epigrafico di età ellenistico-romana

2013

Il lessico utilizzato in iscrizioni di età ellenistico-romana, in cui si fa riferimento al soggiorno di guarnigioni in città, rivela una comunicazione che privilegia la sfera emotiva per ottenere privilegi o sgravi da abusi. In particolare sono oggetto di analisi: decreti civici in onore di comandanti elogiati per l’eutaxia; lettere reali che contengono provvedimenti volti a reprimere gli abusi degli eserciti, probabilmente risposte ad ambascerie delle popolazioni che lamentavano situazioni di disagio; documenti che riguardano città ellenistiche ed imperium Romanum, con ottenimento di esenzione dall’alloggiamento dei soldati attraverso l’intervento di evergeti.

Optimising Training Adaptations and Performance in Military Environment

2018

Abstract Objectives Worldwide decreases in physical fitness and increases in body fat among youth have set challenges for armed forces to recruit physically capable soldiers. Therefore, knowledge of optimizing physical adaptation and performance through physical training is vital. In addition, maintaining or improving physical performance among professional soldiers in various military environments is crucial for overall military readiness. The present review focuses on the effects of military training on physical performance by searching for optimal methods to do it. Design and methods Review article based on selected literature searches using the main keywords ‘physical performance’ and ‘…
