The energy system is currently in a rapid transformation with increasingly growing renewable electricity production. One way through which companies can buy renewable electricity is through long - term corporate Power Purchase Agreements (PPAs), in which they agree on a fix price and other terms with a project developer. To determine a fair fix PPA price, the future electricity market price needs

It is easy to demonstrate the naivety of many people preparing messages for intelligent beings on other planets using pictures. On the other hand, constructivism, which supposes all our perception to rely on social constructs, has long been shown to be untenable, notably by Gibson, who instead suggested that some general ecological principles have to be taken into account. In a parallel fashion, I

This study investigated the impact of well geometry and surface reflectance on the vertical daylight factors of walls in atria with square plan forms under a CIE standard overcast sky. Artificial sky scale model measurements were used to validate predicted values of vertical daylight factors using the software package Radiance. More simulated vertical daylight factors data for a much wider range o

In this note, we investigate relations between tree-level off-shell currents in nonlinear sigma model. Under Cayley parametrization, all odd-point currents vanish. We propose and prove a generalized U(1) identity for even-point currents. The off-shell U(1) identity given in [1] is a special case of the generalized identity studied in this note. The on-shell limit of this identity is equivalent wit

This study investigated the impact of well geometry and surface reflectance on vertical daylight factors on the walls of rectangular atria under a CIE standard overcast sky. The vertical daylight factors predicted using the modelling software Radiance were validated by artificial sky scale model measurements. More simulated data of vertical daylight factors for a very wide range of rectangular atr

Strategic critical minerals are essential materials that will dominate the energy transition and technological revolution. In the context of global climate change and industrial transformation, the geopolitical phenomenon of major powers competing for critical minerals has rapidly emerged, yet relevant research remains relatively limited. Therefore, this paper aims to summarize the geopolitical re

The shift from internal combustion to electric engines is currently transforming the automotive industry. Yet, the business model path forward for electric vehicles (EVs) is still uncertain, as the perspectives of different industry actors, especially incumbents and new entrants deviate. The understanding of varying views regarding business model design thus needs to be intensified. Therefore, the

Daylight plays a major role in making atrium spaces appealing to building users. This appeal is also evident in the spaces adjoining the atrium. A key component of atrium daylighting, especially in tall atria, is the daylight reflected on to the atrium walls. This study examines the impacts of well geometries and different diffuse reflectance distributions of walls on variations of vertical intern

Popular Abstract in English Oil resources are finite; and political and economic factors affecting oil production,together with the environmental damage associated with the increased use of oil by a rapidly growing population, have underscored the need for developing cleaner technologies based on sustainable resources. In this context, any lignocellulosic biomass that is not used in the food chainThe present work was aimed at developing industrial S. cerevisiae strains with improved tolerance to two types of stressors encountered during the fermentation of lignocellulosic biomass that affect ethanol yield and productivity, namely hydrolysate-derived inhibitors and high temperature, and at understanding the response of yeast and mechanisms of adaptation to such stressors. In one part of the

Endwall film cooling upstream of the leading edge (LE) of a vane presents a relatively complex flow phenomenon due to the horseshoe vortices (HVs) generated at the LE region. Upstream of the LE region, the coolant flow has difficulties to eject out. This research work focuses on controlling the jet holes coolant coverage upstream of the LE region. Compound angle holes in staggered arrangement are

A sense can be given, in qualitative rather than quantitative terms, to the three-part distinction, within the semiotics of culture, of Culture, Non-culture, and Extra-culture, by having recourse to the analysis of pronouns into two binary correlations, personality and subjectivity, originally proposed by Benveniste. The present communication will address two related themes: the possible relations
