Denna rapport sammanfattar några studier som på olika sätt syftar till att förbättra metodiken för att analysera samhällsekonomiska effekter av kollektivtrafikinvesteringar. Förbättringarna som behandlas är 1) vikten av att ta med bristande kapacitet (trängsel) i kalkylerna; 2) förbättrade beräkningar av driftskostnader; 3) effekter av tillgänglighet på arbetsmarknad och produktivitet (s k ”wider

For many applications, including future giant telescopes, there is increased interest in structural cables. Usually integrated models, i.e. combined models of structures, optics and control systems are used for modeling of telescopes. Performance of structural cables is non-linear, so often a linearization is needed to include cable models in integrated models of telescopes. We present two differe

The human genome encodes 13 aquaporin isoforms with characteristic substrate specificity that are expressed at specific locations throughout the body. Of these isoforms, AQPs 1-4 serve important functions in renal water reabsorption. Consequently, specific AQP inhibitors have been proposed as 'aquaretics', a new class of drugs suitable to induce diuresis without concomitant salt wasting. Furthermo

This book provides important insights into the domain of interactions between language and cognition, focusing on SPACE and expressions of SPACE. Both literal and metaphorical forms of expression are included. The research reported is carried out within the broad framework of Cognitive Linguistics, which encompasses a wide variety of empirical methods and research topics. Our approach to the const

Consumer awareness regarding food production and food content is steadily growing. An alternative to the current model of global food chains is local production of food and local sales of food at farmers’ markets. This chapter assesses the social and economic benefits of farmers’ markets both for the farmers taking part in the markets and for the consumers purchasing the products on sale. The deve

In this article the authors reflect upon and critically examine signs of a contradiction in higher education which they discuss in terms of the tension between 'use value' and 'exchange value'. Use value here represents learning as something valuable ‘in itself’ whereas exchange value represents learning as an achievement of grades and credits to be ‘traded’ on a market. Their aim in this article

To evaluate the influence of hard exudates on macular function in patients with diabetic retinopathy. METHODS: Thirty seven eyes from 27 diabetic patients, aged 57 +/- 14 years, diabetes duration 12.5 +/- 9 years, not previously treated with photocoagulation, underwent fundus photography, multifocal electroretinography (mfERG) and optical coherence tomography (OCT). Hard exudates were graded from

In atherosclerotic vascular disease, endothelial dysfunction is induced by risk factors such as arterial hypertension, hypercholesterolemia, and tobacco use. In fl ammatory mechanisms and in fl ammatory cytokines play important roles in all of these mechanisms, and the different steps in atherogenesis involve cytokines as in fl ammatory promoters, stimulating the expression of proatherogenic genes

Bakgrund Framväxten av hälsoapplikationer som gör det möjligt för patienter att kontakta och kommunicera med vårdpersonal digitalt kan förändra hur patienter ser på sin vård och hur de kontaktar vårdpersonalen (WHO, 2011). Digitala system kan också, utifrån sin design, ge förutsättningar för relationscentrerad vård genom att patienterna ges möjlighet att, i samverkan med vårdpersonalen, vara aktiv

Background: In Europe, residential care homes (RCHs) rather than hospitals are the most common care facilities for the older adult and the place where most deaths occur in this age group. There is a lack of knowledge regarding end-of-life (EOL) discussions and how they correlate with symptoms and symptom relief. Objective: The aim was to examine the correlation between EOL discussions and symptom

Gemensamt ägande av energi har funnits i Sverige i många år. Med Ren energi-paketet från EU etableras nu en lagstiftning som introducerar ”energigemenskaper” som en ny organisationsform på energimarknaden. Målet med denna rapport är att introducera energigemenskap, hur det beskrivs i Ren energi-paketet och i Energimarknadsinspektionens förslag till ny lag för Energigemenskaper i Sverige. I rapport

High-ductility ductile iron was alloyed with 0-1.8wt% Ni in this paper. The low-temperature impact toughness test and corrosion test of simulated seawater static whole-soaking were conducted to research the effect of nickel on the low-temperature impact toughness and corrosion resistance of high-ductility ductile iron. The results show that with nickel increasing, the impact toughness under low te

Våra röda blodkroppar lever i genomsnitt 120 dagar och bryts därefter ner avmakrofagerna, immunsystemets medfödda städare av både främmande och egnaceller. De röda blodkropparnas uppgift är att transportera syre från lungorna tillkroppens olika vävnader och föra tillbaka koldioxid. Men vad händer om de rödablodkropparna bryts ner ovanligt snabbt eller helt enkelt inte produceras i tillräckligtsnabRed blood cells are are plentiful, flexible and essential. They are the most abundant cell in our body and their mainobject is to carry oxygen, which is essential for cellular respiration. The formation of red blood cells is callederythropoiesis. Erythropoiesis is intimately coupled to cell division and mitochondrial function. Aberrations in thesetwo processes are often associated with red blood c
