Elsystemet står inför en stor förändring som kommer av omställningen till ett utsläppsfritt samhälle. Elsystemet är en central del av vår samhälleliga infrastruktur och dess utveckling har till stor del styrts av politiska beslut även om marknaden fått allt större utrymme sedan 1990-talet. Stora tekniska system utvecklas alltid i samklang med samhällets institutioner där samhällets ramar och regl

Scan circuit testing generally causes excessive switching activity compared to normal circuit operation. This excessive switching activity causes high peak and average power consumption. Higher peak power causes, supply voltage droop and excessive heat dissipation. This paper proposes a scan cell reordering methodology to minimize the peak power consumption during scan shift operation. The propose

It has been suggested that neural mechanisms may contribute to effects of the incretin hormones, and, therefore, also to the effects of dipeptidyl peptidase (DPP-4) inhibition. We therefore examined whether muscarinic mechanisms are involved in the stimulation of insulin secretion by DPP-4 inhibition. Fasted, anesthetized mice were given intraperitoneal saline or the muscarinic antagonist atropine

The purpose of this work is the investigation of some constitutive and configurational aspects of phenomenological model formulations for a class of materials with history-dependent gradient microstructure. The assumption that the behavior of a material point is affected by history-dependent processes in a finite neighbor of this point yields an extended continuum characterized by non-simple mater

Summary Background: The aim was to assess sexual risk-taking behaviour in a sample of Swedish youth who were sexually active while travelling abroad and to examine possible associations with sexual risk-taking behaviour during such travel.Methods: From a population-based sample of 2189 Swedes 18e29 years 768 who were sexually active while abroad, were assessed by a questionnaire concerning socio-dSummary Background: The aim was to assess sexual risk-taking behaviour in a sample of Swedish youth who were sexually active while travelling abroad and to examine possible associations with sexual risk-taking behaviour during such travel.Methods: From a population-based sample of 2189 Swedes 18e29 years 768 who were sexually active while abroad, were assessed by a questionnaire concerning socio-d

BACKGROUND: We report the surgical treatment of a consecutive series of scan negative patients with the intention of unilateral parathyroid exploration with the aid of intraoperative quick PTH (qPTH).MATERIALS AND METHODS: The study included 35 consecutive sestamibi scan negative patients (27 women, eight men) with sporadic pHPT subjected to first time surgery. Median age was 70 years and median p

High resolution photoemission applied to the C 1s and Rh 3d core levels has been used to investigate the adsorption sites at low temperature of CO on the Rh(111) single crystal surface as a function of CO coverage. Two different sites are found to be occupied by the CO molecules. At coverages up to 0.5 monolayers the majority of the molecules are found to adsorb in on-top sites whereas at higher c

The International Aid Transparency Initiative (IATI) is an agreement establishing a common standard for the reporting of information about aid and development funding. Signatories include nations, intergovernmental organizations (IGOs), nongovernmental organizations (NGOs), civil society organizations (CSOs) and private foundations, which together account for approximately 80 per cent of all inter

This paper deals with a novel constitutive framework suitable for non-coherent interfaces, such as cracks, undergoing large deformations in a geometrically exact setting. For this type of interface, the displacement field shows a jump across the interface. Within the engineering community, so-called cohesive zone models are frequently applied in order to describe non-coherent interfaces. However,

Recent genome-wide association studies confirm that human leukocyte antigen (HLA) genes have the strongest associations with several autoimmune diseases, including type 1 diabetes (T1D), providing an impetus to reduce this genetic association to practice through an HLA-based disease predictive model. However, conventional model-building methods tend to be suboptimal when predictors are highly poly

The main limitation of operating sensor networks autonomously is the finite battery capacity of sensor nodes. Sensors are usually operated at low duty cycle; that is, they remain in active mode for short duration of time, in order to prolong the network lifetime. However, operating at low duty cycle may result in significant performance degradation in system operation. Hence, in this work, we quan

The purpose of this contribution is to present a survey of the recent developments in constructing composite science and technology (S&T) indicators on a national level as well as new evidence of the variability of such S&T indicators which opens the gateway to "country-tuning". It has become standard practice to combine several indicators for science, technology, and innovation to form co

The purpose of this qualitative 2-year follow-up study was to obtain a deeper understanding of motivation for change towards an active and independent life in patients with prolonged musculoskeletal disorders and to explore and identify personal resources that might influence such improvements. Data collection and analysis were performed according to the qualitative case study design. An initial c

Hydrogenolysis of biodiesel-derived glycerol to value-added chemicals has emerged as an innovative approach to biowaste valorization for a more sustainable society. In the present work, Ru catalysts on Al2O3/AlF3 supports with different AlF3 content were prepared by the aqueous incipient wetness method and tested in the reaction of glycerol hydrogenolysis for the first time. The prepared catalysts

A successful previous project E-GIS (Leonardo da Vinci programme) was implemented during 2002-2006. The objectives were to establish co-operation between European Universities and GIS users and to develop modularised courses intended for flexible learning. Ten partners from six European countries (BU, LT, NO, NL, PT, SE) participated. During the project a study program, 100 % Internet based, corre

This paper presents a practical risk analysis method for critical, large-scale IT systems in an organisation. The method is based on reliability block diagram modelling and was adapted to fit the requirements of governmental organisations and to reduce the effort required to capture complex failure behaviour. Through the use of different failure categories the risk analysis can be simplified, the
