Fastighetsägare som prosumenter – stödstrukturer och hinder

Solceller har en viktig roll att fylla för att uppnå politiskt fattade mål om 100%hållbart elsystem. Det är rimligt att anta att det är i bebyggelsen som en storutbyggnad kommer att behöva ske eftersom det är existerande strukturermed nätanslutningar där det också finns möjlighet att använda den solel somproduceras. Fastighetsägare blir därmed en viktig aktörsgrupp att engagera.En relativt outfors

Developmental changes in the rules for B cell selection*

The autoimmune checkpoint during B cell maturation eliminates self-antigen reactive specificities from the mature B cell repertoire. However, an exception to this rule is illustrated by B-1 cells, an innate-like self-reactive B cell subset that is positively selected into the mature B cell pool in a self-antigen-driven fashion. The mechanisms by which B-1 cells escape central tolerance have puzzle

Traffic Networks via Neural Networks : Description and Evolution

We optimize traffic signal timing sequences for a section of a traffic net- work in order to reduce congestion based on anticipated demand. The system relies on the accuracy of the predicted traffic demand in time and space which is carried out by a neural network. Specifically, we design, train, and evaluate three different neural network models and assert their capability to describe demand from

Att ta en tugga av havet. Om blå åkrar, grön ekonomi och den smarta tångens svåra resa

The marine environment has an important role to play in the change-over to a green economy where the blue fields of the sea can form new and ex- panded cultivation spaces. Over the recent years there has been an increasing interest for seaweed as food in Europe. In this article we follow the sea- weed’s journey into the Swedish cuisine by letting it lead us to different places and actors. Seaweed

Stratigraphy of the Gorstian and Ludfordian (upper Silurian) Hemse Group reefs on Gotland, Sweden

The Hemse Group is one of the least understood stratigraphic units of the Silurian sequence of Gotland, Sweden. New results from airborne transient electromagnetic (ATEM) measurements in combination with previously published data from field studies and geophysical investigations shed new light on carbonate platform development during the early- to mid-Ludlow Hemse Group. ATEM reveals a transgressi

Tourism, technology and ICT : a critical review of affordances and concessions

The digital information age has changed global tourism in profound ways. Information and Communication Technologies (ICT) are pervasive, and they have become inextricably linked with contemporary consumer cultures. ICTs represent affordances: to apprise, plan, order, network, socialize, stream, transact and rate. These are remunerated with concessions in the form of consumer data that is used to d

Phonon-Assisted Hot Carrier Generation in Plasmonic Semiconductor Systems

Plasmonic materials have optical cross sections that exceed by 10-fold their geometric sizes, making them uniquely suitable to convert light into electrical charges. Harvesting plasmon-generated hot carriers is of interest for the broad fields of photovoltaics and photocatalysis; however, their direct utilization is limited by their ultrafast thermalization in metals. To prolong the lifetime of ho

Influence of system operation on the design and performance of a direct ground-coupled cooling system

Sizing of borehole heat exchangers (BHEs) for direct ground cooling systems (DGCSs) is a critical part of the overall system design. This study investigates the thermal performance and sizing of a DGCS with two different operation strategies using experimental and simulation approaches. The traditional on/off operation strategy keeps a constant room temperature. The continuous operation strategy h

Acoustic propagation in variable sound speed profiles

An important topic in the area of airborne sound propagation is the prediction of sound propagation above an impedance ground with an atmospheric profile whose sound speed varies with height. Even if this problem is simple in concept, it leads to complications for general velocity profiles. This work illustrates the existence of a large class of realistic atmospheric profiles for which analytical

Natural Resources and Divergence : A Comparison of Andean and Nordic Trajectories

Is the 'natural resource curse' destiny? Are different ways to link natural resources and economic development? Using two particular regions as case studies, this edited collection examines the divergent development paths of natural resource rich countries over the past two centuries. Bolivia, Chile and Peru are neighbour states with a common history and are globally known by their mining endowmen
