Abstract in UndeterminedSometimes energy security is used as an advocacy for renewable energy systems. Although renewable energy systems can surely have such characteristics they will not per se solve all types of security problems, and new problems will most certainly arise. In this paper, energy security aspects of renewable energy systems are analysed taking the starting point in a broad typolo

This research explores socio-technical perspectives of the demand-side management strategy of using the built environment for short term thermal energy storage. Here conceptualised as a niche innovation within the Danish socio-technical district heating landscapes, the research explores potentials and limitations of this building energy flexibility strategy from the perspective of district heating

In fifth generation district heating and cooling (5GDHC), the temperature range of the heat source is wider then in current common heat pump systems. The results of this study show that the heat pumps and chillers that are available in the market are not well adapted to 5GDHC applications due to the wide working range of 5GHDC. In order to maintain a high efficiency, current design parameters shou

In the continuous work on improving product quality and reducing energy consumption at The Danish Steel Works Ltd. the importance of optimal furnace operation has been recognised in many different contexts. Therefore a joint project with the Department of Automatic Control at Lund Institute of Technology has been started with the purpose of developing a novel slab temperature control algorithm for

Mojtaba Khamenei’s rise to Iran’s supreme leadership represents the consolidation of dynastic power within the Islamic Republic. Long operating behind the scenes through the Supreme Leader’s office and the Islamic Revolutionary Guards, he has been widely viewed as the most likely successor to his father. His leadership signals continuity with the regime’s totalitarian structure and suggests a furt

Suppressor of cytokine signaling 2 (SOCS2) is known as a feedback inhibitor of cytokine signaling and is highly expressed in primary bone marrow (BM) cells from patients with chronic myeloid leukemia (CML). However, it has not been established whether SOCS2 is involved in CML, caused by the BCR/ABL1 fusion gene, or important for normal hematopoietic stem cell (HSC) function. In this study, we demo

There are many reasons why heat transfer and heat exchangers play a key role in the development of sustainable energy systems as well as in the reduction of emissions and pollutants. In general, all attempts to achieve processes and thermodynamic cycles with high efficiency, low emissions, low costs include heat transfer and heat exchangers to a large extent. It is known that sustainable energy de

European renewable energy policy has gone through a remarkable development over the last few years. It has moved from being a predominantly national-level concern with a focus on environmental issues to a top European policy agenda item where security of supply and competitiveness concerns figure with equal prominence. In 2007 and 2008 EU established a very forceful policy framework with ambitiou

Perennial energy crop development is just starting in Poland and there are great expectations on this sector to make a substantial contribution to the achievement of renewable energy targets defined in the European Union (EU) directive 28/2009/EC. Insights into the economics of energy crop production may lead to a better understanding of the dynamics of developments in the field. This work address

The aim of this work was to explore the possibility of mixed feedstocks utilization using acid-catalyzed steam pretreatment in the context of forest biomass. Three steam pretreatment conditions were applied to characterize the interactions between spruce (softwood) and poplar (hardwood) that were concurrently processed by SO2-catalyzed steam pretreatment and enzymatic hydrolysis. The effects of bl

We use data from the Radial Velocity Experiment (RAVE) and the Tycho-Gaia astrometric solution (TGAS) catalogue to compute the velocity fields yielded by the radial (VR), azimuthal (Vϕ),and vertical (Vz) components of associated Galactocentric velocity. We search in particular for variation in all three velocity components with distance above and below the disc midplane, as well as how each compon

Background: Caldicellulosiruptor saccharolyticus is an attractive hydrogen producer suitable for growth on various lignocellulosic substrates. The aim of this study was to quantify uptake of pentose and hexose monosaccharides in anindustrial substrate and to present a kinetic growth model of C. saccharolyticus that includes sugar uptake on defined and industrial media. The model is based on Monod

The environmental footprint of IT products are significant and, in spite of manufacturing and product design improvements, growing consumption of electronics results in increasing absolute environmental impact. Computers have short technological lifespan and a lot of the in-build performance, although necessary, remains idling for most of the time. Today, most of computers used in non-residential
