Numerical Procedures and their Practical Application in PV Module Analyses. Part IV: Atmospheric Transparency Parameters - Application
2020
Abstract The presented article relates to aspects of PV module testing using natural sunlight in outdoor conditions. It is a continuation of the article Part III: parameters of atmospheric transparency - determining and correlations. This article discusses the practical application of the indexes: atmosphere purity - k Tm , diffused component content - k s/o , beam clear sky index - K b - in testing various modules in outdoor conditions. Their influence on the conversion of modules made from various absorbers and various technologies is demonstrated. Their practical application in module testing in outdoor conditions is described and it - has been demonstrated that the results of the analys…
Applications of a new set of methane line parameters to the modeling of Titan's spectrum in the 1.58 μm window
2012
International audience; In this paper we apply a recently released set of methane line parameters (Wang et al., 2011) to the modeling of Titan spectra in the 1.58 mu m window at both low and high spectral resolution. We first compare the methane absorption based on this new set of methane data to that calculated from the methane absorption coefficients derived in situ from DISR/Huygens (Tomasko et al., 2008a; Karkoschka and Tomasko, 2010) and from the band models of Irwin et al. (2006) and Karkoschka and Tomasko (2010). The Irwin et al. (2006) band model clearly underestimates the absorption in the window at temperature-pressure conditions representative of Titan's troposphere, while the Ka…
Servicios de intermediación en línea en Europa : diseño de un sistema específico de solución de controversias
2021
Este trabajo analiza el sistema de solución de controversias específicamente diseñado, con la introducción de alternativas a la jurisdicción, en el Reglamento (UE) 2019/1150 sobre el fomento de la equidad y la transparencia para los usuarios profesionales de servicios de intermediación en línea, que ha entrado recientemente en vigor.
Derecho de acceso a la información : el desafío de una sociedad guiada por la transparencia en el ordenamiento jurídico español
2021
This study will address the two aspects of rights linked to information, the right to information and the right to information, to end with the formulation of some conclusions that, distancing themselves from a mere summary, seek to encourage doctrinal and political debate on assumptions that, being peacefully settled, should be reformulated in light of the repeated crisis of transparency. For this, it will be articulated by addressing, first, the most significant aspects of the right to information and its link with the right to freedom of expression, as well as the new challenges that these rights face in the digital age, to then analyze the right to information, its regulation in the Spa…
Rydberg excitation of cold atoms inside a hollow core fiber
2017
We report on a versatile, highly controllable hybrid cold Rydberg atom fiber interface, based on laser cooled atoms transported into a hollow core Kagom\'{e} crystal fiber. Our experiments are the first to demonstrate the feasibility of exciting cold Rydberg atoms inside a hollow core fiber and we study the influence of the fiber on Rydberg electromagnetically induced transparency (EIT) signals. Using a temporally resolved detection method to distinguish between excitation and loss, we observe two different regimes of the Rydberg excitations: one EIT regime and one regime dominated by atom loss. These results are a substantial advancement towards future use of our system for quantum simulat…
Polylactic is a Sustainable, Low Absorption, Low Autofluorescence Alternative to Other Plastics for Microfluidic and Organ-on-Chip Applications
2020
Organ-on-chip (OOC) devices are miniaturized devices replacing animal models in drug discovery and toxicology studies. The majority of OOC devices are made from polydimethylsiloxane (PDMS), an elastomer widely used in microfluidic prototyping, but posing a number of challenges to experimentalists, including leaching of uncured oligomers and uncontrolled absorption of small compounds. Here we assess the suitability of polylactic acid (PLA) as a replacement material to PDMS for microfluidic cell culture and OOC applications. We changed the wettability of PLA substrates and demonstrated the functionalization method to be stable over a time period of at least 9 months. We successfully cultured …
European Union Directive: the 8th company law directive on discosure and transparency

Abstract not needed because the work is a voice of an encyclopedia
Oneri di sbilanciamento (diritto dell'energia)
2018
The article aims to explore to what extent consumers protection, as principle constitutionally guaranteed by art.38 of EU’s Charter of Fundamental Rights, should affect the rules governing the electricity dispatching service and the balancing system. On a market such as the electricity market, where demand is inflexible and the product concerned cannot be stored, electricity dispatching service is designed to ensure that, within the national transmission system, the supply of electricity matches demand, thereby guaranteeing security and continuity in the energy supply. Transparent market-based mechanisms for the supply and purchase of electricity needs to be combined with balancing measures…
The Role of Institutions in the Migration of Corporate Governance Practice into Emerging Economies The Case of Africa
2016
This study examines the role of institutional environment in influencing the migration of corporate governance best practice into 22 emerging African economies. Using a unique and comprehensive sample hand-collected sample of 202 IPO firms from across the continent we adopt a novel institutional logics perspective in studying the diffusion of CEO salary disclosure – a central element of corporate transparency. Our findings reveal that the adoption of CEO salary disclosure by firms is more likely in more homogenous informal institutional contexts. Complementarities arising from disclosure originating from an Anglo-American shareholder value governance framework and indigenous formal institut…
Nonlinear pulse deceleration using photorefractive four-wave mixing
2009
We investigate the possibilities of the backward four-wave coupling based on the nonlocal photorefractive response for the nonlinear deceleration of light pulses. The presence of an additional external variable parameter—the pump intensity ratio—allows to improve the output characteristics of the decelerated pulses compared to those typical of the two-wave coupling. In particular, large delay times of the output pulses can be achieved without their strong amplification. This positive distinctive feature of the pulse deceleration occurs far from threshold of the mirrorless optical oscillation.
