Hög energieffektivitet och god fordonsdynamik är två av de viktigaste fokusområdena för drivsystem i personbilar. En central komponent i BorgWarner:s produkter för momentöverföring är en lamellkoppling som regleras med hjälp av trycksatt olja från en hydraulisk axialkolvpump. Ett alternativ för att reducera energiförbrukningen och samtidigt förbättra pumpens prestanda är att variera pumpens deplacEnergy efficiency and good vehicle dynamics are two of the main focus areas for passenger car drive systems. A central component in BorgWarner’s torque transfer products is a multi-plate clutch which is actuated by pressurized oil from a hydraulic axial-piston pump. One way to reduce the energy consumption and improve the performance of the pump is to let the displacement of the pump vary dependin

This essay investigates how new innovations are introduced and implemented in the transportation system, and serves to illustrate this through a case study of Skånetrafiken and its plans to integrate mobility services. Mobility stands at the precipice of structural changes which will effectively challenge the social position of the car as the most common and self-evident choice of transportation.

Today, about one-third of all produced food and drinks are neither eaten nor drunk and turn into food waste. To put this number into perspective, the amount of wasted food would feed three billion people each year. From 2012 to 2018, Swedish grocery stores have more than doubled their amount of food waste, now reaching 100 000 tons per year. This is an outcome of deeply rooted norms of hygiene and

The growing proportion of green energy in the electricity grids brings with it a growing need of grid stabilizing resources to counteract the inherent intermittency of renewable energy resources. This is where the grid scale energy storages come in handy. They efficiently offset the intermittencies of solar, wind etc. resources by energy arbitrage and peak shifting. This thesis looks into the econ

Climate change are starting to receive more attention, even so, transport sector is responsible for approximately 20% of energy related GHG emission, which still has increasing trend. Solutions based on using information and communication technologies are started to be used for reducing anthropogenic GHG emissions and replacing business related travels. Meetings that is held by using ICT, can save

This paper challenges the dominant conceptualization of authentic self-presentation as real, genuine or true expression of inner essence or social identity (Lehmann et al., 2019) and calls for its redefinition in light of the rise of AI-generated content within algorithmically mediated online environments. Authenticity has long been central to identity construction and self-presentation, traditionThis paper challenges the dominant conceptualization of authentic self-presentation as real, genuine or true expression of inner essence or social identity (Lehmann et al., 2019) and calls for its redefinition in light of the rise of AI-generated content within algorithmically mediated online environments.

Purpose: Cancer affects a great number of people during working life, and tailored interventions targeting this population are important. The present study, focused on the developmental phase of a work-oriented intervention, aimed to describe work-related experiences and needs among people undergoing curative cancer therapy. Methods: People (n = 22, age md 55 years, range 39–64, purposive sampling

Privacy-preserving blueprint schemes (Kohlweiss et al., EUROCRYPT’23) offer a mechanism for safeguarding user’s privacy while allowing for specific legitimate controls by a designated auditor agent. These schemes enable users to create escrows encrypting the result of evaluating a function y=P(t,x), with P being publicly known, t a secret used during the auditor’s key generation, and x the user’s

By exposing photosystem II (PSII) samples to an incrementing number of excitation flashes at room temperature, followed by freezing, we could compare the Mn-derived multiline EPR signal from the S-2 oxidation state as prepared by 1, 5, 10, and 25 flashes of light. While the S-2 multiline signals exhibited by these samples differed very little in spectral shape, a significant increase of the relaxa

Changes in agricultural land-use have been suggested to contribute to the decline of several bird species through negative effects on their food supply during breeding. One important change in land-Use has been loss of pastures, especially permanent pastures. In this study we investigated how different forms of agricultural land-use affected foraging success or a declining bird species, the Europe

Objective To describe the views of people, 65 years and over, receiving continuous public care and service, on prioritization and resource allocation in health care, in relation to gender, age, housing, health-related quality of life (QoL) and degree of activities of daily living (ADL) dependency. Background How older people receiving continuous public care and service view prioritization and res

To study the effects of elevated ozone concentration on methane dynamics and a sedge species, Eriophorum vaginatum, we exposed peatland microcosms, isolated by coring from an oligotrophic pine fen, to double ambient ozone concentration in an open-air ozone exposure field for four growing seasons. The field consists of eight circular plots of which four were fumigated with elevated ozone concentrat

The X chromosome (chrX) represents one potential source for the "missing heritability" for complex phenotypes, which thus far has remained underanalyzed in genome-wide association studies (GWAS). Here we demonstrate the benefits of including chrX in GWAS by assessing the contribution of 404,862 chrX SNPs to levels of twelve commonly studied cardiometabolic and anthropometric traits in 19,697 Finni

BACKGROUND: The Global burden of disease and injuries study (GBD 2015) reports expected measures for years of life lost (YLL) based on socio-demographic index (SDI) of countries, as well as the observed measures. In this extended GBD 2015 report, we reviewed total and cause-specific deaths and YLL for Iran and all its neighboring countries between 1990 and 2015.METHODS: We extracted data from the

Low-molecular-weight heparin (LMWH) is often recommended as a bridging therapy during temporary interruptions in warfarin treatment, despite lack of evidence. The aim of this study was to see whether we could find benefit from LMWH bridging. We studied all planned interruptions of warfarin within the Swedish anticoagulation register Auricula during 2006 to 2011. Low-molecular-weight heparin bridgi

Despite numerous studies of selection on position and number of spectral vision bands, explanations to the function of narrow spectral bands are lacking. We investigate dragonflies (Odonata), which have the narrowest spectral bands reported, in order to investigate what features these narrow spectral bands may be used to perceive. We address whether it is likely that narrow red bands can be used t

Mega-projects are a growing phenomenon worldwide. More and more projects are started and they grow ever bigger in size. At the same time, there is overwhelming evidence that mega-projects tend to run late, overrun in terms of costs and fail to deliver the expected benefits. Paradoxically, more and more money is invested in projects that fail to deliver on their promises.This dissertation analyses

Objectives: To determine predictors of renal relapse and end-stage renal failure (ESRF) in patients with ANCA-associated vasculitis. Methods: Data from four European Vasculitis Society randomized controlled trials, conducted roughly simultaneously between 15 March 1995 and 30 September 2002, was pooled to determine predictors of long-term renal outcome. The respective trial inclusion criteria cove

The carbon cycle of the terrestrial biosphere plays a vital role in controlling the global carbon balance and, consequently, climate change. Reliably modeled CO2 fluxes between the terrestrial biosphere and the atmosphere are necessary in projections of policy strategies aiming at constraining carbon emissions and of future climate change. In this study, SMOS (Soil Moisture and Ocean Salinity) L3
