A new low pressure fuel system implementation for Scania’s trucks is being investigated. The main challenge consists in exchanging the mechanical pump with electrical pumps. The electrical pumps must then be controlled to supply exactly the demanded amount of fuel at the required pressure. System redundancy allows a lot of degrees of freedom influencing the final performance. This thesis studies t
Gone are the days when women were exclusively confined to care work in the private sphere and men dominated in the public sphere. Still, the increase in the number of women in gainful employment has not engendered a more equitable division of family responsibilities inside the family unit. In fact, the birth of a child often entails in itself a ‘re-traditionalisation’ of working and family pattern
Purpose: A well-functioning curbside system must consider several properties, such as the location of collection points, from a logistical standpoint to ensure efficient hauling and transportation. The collection point itself should also promote a good working Environment for the collection personnel. However, many older urban areas were not designed with modern logistical and environmental aspect
The fast-increasing demand and relatively slow growth of infrastructure capacity are providing a strong motivation for research in real-time urban traffic controls that make the best use of novel sensing in order to increase efficiency and resilience of the transportation system. In our contribution, we focus on a class of dynamic feedback traffic signal control policies that are based on a genera
Despite numerous recent studies of Italic textiles and textile production etc., no systematic study has so far been attempted regarding the textile terminology of Italic languages besides Latin. The present study seeks to remedy this, making a first step into the textile terminology of Sabellic languages, predominantly Oscan and Umbrian. There are two types of sources for Sabellic textile terminol
Purpose: The purpose of this paper is to advance knowledge about the mechanisms behind, and the implications of, varying involvement in digitally enhanced employee-driven innovation (EDI) by studying how a firm integrates a web-based tool in the organization of its EDI process. Design/methodology/approach: Based on a qualitative in-depth interview study with managers and employees at one high-perf
We show that the 2.4σ signal of the leptonic flavor violating (LFV) Higgs boson decay h→μτ, as observed by the CMS Collaboration recently, can be explained by a certain class of two-Higgs doublet models that allow controllable flavor-changing neutral current with a minimal number of free parameters. We postulate that (i) the alignment limit is maintained, which means the lightest neutral scalar (h
November 2011 saw the opening of the exhibition "Archeovirtual" organized by CNR ITABC - Virtual Heritage Lab - and V-MusT Network of Excellence, in Paestum, Italy, under the general direction of BMTA1. The event, that was part of a wider European project focus on virtual museums, turned to be a great opportunity to show many different projects, applications and installations about Virtual Reality
Avhandlingens titel "Kustnära yrkesfiske i förändring. Från mångsysslare till entreprenör" hänvisar till de förändringar som fiskenäringen har genomgått under flera decennier. Fiskenäringen har rationaliserats samtidigt som besöksnäringen vid kusten expanderat. Antalet yrkesfiskare i kustnära yrkesfiske har därför minskat och näringen måste förhålla sig till nya informella krav och förväntningar pIn this dissertation inshore commercial fisheries are being studied from a cultural analytical perspective with a focus on service production and hospitality. The dissertation title, ”Inshore commercial fisheries in change. From pluri-activity to entrepreneurship”, refers to the multiple kinds of change that the fishing industry has undergone for a long period in time. They include rationalization
Background: This case control study aimed to investigate whether symptoms of sexual dysfunction are more common in males from infertile couples than in the general population and to explore whether symptoms of sexual dysfunction are associated to hypogonadism. Objectives: Participants were 165 subfertile men in infertile heterosexual relationships, 18–50 years of age, with sperm concentrations < 1
Ship traffic is a major source of aerosol particles, particularly near shipping lanes and harbours. In order to estimate the contribution to exposure downwind of a shipping lane, it is important to be able to measure the ship emission contribution at various distances from the source. We report on measurements of atmospheric particles 7-20 km downwind of a shipping lane in the Baltic Se
A majority of households in developing countries use biomass energy for cooking and heating due to its affordability and accessibility. However, unsustainable biomass use leads to deforestation, environmental degradation and climate change. The pollution from open burning of biomass is a major health concern especially for women and children as they spend a lot of time in the kitchen. Biochar-prod
The metal-poor stars in the bulge are important relics of the Milky Way's formation history, as simulations predict that they are some of the oldest stars in the Galaxy. In order to determine if they are truly ancient stars, we must understand their origins. Currently, it is unclear if the metal-poor stars in the bulge ([Fe/H] < -1 dex) are merely halo interlopers, a unique accreted population, pa
Choosing to continue working after retirement eligibility can attract both negative and positive sentiments from the general public. Studies examining the motivations of older workers have so far been conducted in times of relative social and economic stability. However, little is known about what it means for older workers to work during a lockdown or pandemic situation. The present longitudinal
Exclusive dimuon production in ultraperipheral collisions (UPC), resulting from photon-photon interactions in the strong electromagnetic fields of colliding high-energy lead nuclei, PbPb(γγ) → μ+μ-(Pb(∗)Pb(∗)), is studied using Lint = 0.48 nb-1 of √sNN = 5.02 TeV lead-lead collision data at the LHC with the ATLAS detector. Dimuon pairs are measured in the fiducial region pT,μ > 4 GeV, |ημ| <2.4, i
There is a battle in the supermarket isle, a battle between what the consumer wants and what the retailer and others want her to see, and subsequently to buy. Product packages and displays contain a number of features and attributes tailored to catch consumers' attention. These are what we call external factors comprising the visual saliency, the number of facings, and the placement of each produc
The lipid-protein film covering the interface of the lung alveolar in mammals is vital for proper lung function and its deficiency is related to a range of diseases. Here we present a molecular-level characterization of a clinical-grade porcine lung surfactant extract using a multitechnique approach consisting of 1H-13C solid-state nuclear magnetic spectroscopy, small-And wide-Angle X-ray scatteri
Material and energy costs represent about 50% of the operating costs incurred by European small and medium-sized enterprises (SMEs). Although the potential for resource efficiency improvements is high, the necessary awareness and human resource capacities to explore this potential are limited. Existing tools for exploration of resource efficiency improvement potentials have several shortcomings: t
