The modernisation of Swedish households during the twentieth century prompted a considerable productivity growth in household production. This paper examines the association between this process and the allocation of female time in Swedish urban households during the period 1920-1990. Estimates presented in the paper suggest a minimum potential time reduction for a fixed volume of routine househol
Various ecosystems, including shallow lakes, are suggested to possess alternative stable state dynamics. The response of such systems to environmental change is non-linear and not fully reversible, which calls for identification of feedback mechanisms and subtle changes connected to structural stability. Here, we used a 25-year data series on water chemistry to make inferences on processes prior t
Purpose - This paper has three purposes. The first is to introduce the concept of fantasy, based on Lacanian pyschoanlysis, in order to link theoretically the role of narrative and affect in organizational strategies of control. The second is to use this concept to illuminate the fantasmatic as well as ideological character of so-called "market rationality." The third is to reveal three dominant f
The concentration of cholesterol in cell membranes affects membrane fluidity and thickness, and might regulate different processes such as the formation of lipid rafts. Since interpreting experimental data from biological membranes is rather intricate, investigations on simple models with biological relevance are necessary to understand the natural systems. We study the effect of cholesterol on th
Oxy-fuel combustion is one of the proposed technologies which have the potential to achieve zero CO2 emission. Strontium cobalt based perovskite oxygen carriers are promising materials for air separation with a high selectively for oxygen. And these perovskites can produce an oxygen enriched carbon dioxide stream for an oxy-fuel combustion process. The relatively low oxygen production yield may be

Avhandlingen fokuserar på musikdramaturgi i opera som har en story. Jag tycker att min egen musik blir bättre när jag skriver opera än konsertverk, frågan är varför? Syftet är att undersöka förhållandet story och musik och hur det påverkar komponerandet. Förloppet är undersökningens utgångspunkt eftersom story och musik pågår parallellt i tiden. Den konstnärliga verksamheten tas metodiskt i anspråTitle: The Twofold Rhythm of Duration in Opera. The Musical Dramaturgy of the Car Radio Opera "Cleansing of the Soul through Fun and Games". This thesis focuses on musical dramaturgy in operas with a story. I believe my own music is better when I write operas than instrumental music. The question is why? The aim of this thesis is to investigate the relationship between story and music and see how
AIM AND OBJECTIVE: To describe the study design of a randomised controlled trial with the aim of comparing two different regimes for children with newly diagnosed type 1 diabetes; hospital-based care and hospital-based home care. BACKGROUND: Procedures for hospital admission and sojourn in connection with diagnose vary greatly worldwide and the existing evidence is insufficient to allow for any c
Preface: This report has been produced in order to celebrate the 60th anniversary of professor Lars Erik Nevander on the 11th of November, 1981. A number of topics are presented within the field of building physics. They relate to heat transfer in buildings, air infiltration, moisture darnages etc, varying from energy conservation aspects to failures of the building and its design for moisture pro
Invasive species can displace natives, and thus identifying the traits that make aliens successful is crucial for predicting and preventing biodiversity loss. Pathogens may play an important role in the invasive process, facilitating colonization of their hosts in new continents and islands. According to the Novel Weapon Hypothesis, colonizers may out-compete local native species by bringing with
Popular Abstract in Swedish POPULÄRVETENSKAPLIG SAMMANFATTNING Halsbränna och sura uppstötningar är vanliga åkommor i den svenska befolkningen där upp till 20 procent av de tillfrågade uppger sig ha besvär av dessa symtom varje vecka. Både halsbränna och sura uppstötningar anses vara symtom på att magsäcksinnehåll flödar tillbaka upp genom övre magmunnen till matstrupen sk gastroesofageal reflux.This thesis investigates several aspects on gastroesophageal reflux disease (GERD) and associated complications as Barrett’s esophagus and esophageal adenocarcinoma. I. To clarify the natural course of GERD, a pH-metry verified cohort was re-evaluated after 20 years. The course of GERD may well be progressive. A statement based on the evidence that reflux induced complications as esophagitis and
Seed particles of elements or compounds which may or may not form alloys are now used extensively in promoting well-controlled nanowire growth. The technology has evolved following the well-known Vapour-Liquid-Solid (VLS) model which was developed over 40 years ago. This model indicates that a liquid alloy is formed from the seed particle and the growth precursor(s), resulting in crystal growth by
Thesis purpose: In order to contribute to Consumer Culture Theory, as well as critical dimensions in the foodie literature namely authenticity, democracy/distinction and gender, the study’s aim is to explore how discourses and socio-cultural meanings underlie identity constructions in the specific sourdough culture. Theoretical framework: As no research addresses the sourdough phenomenon directly
The construction sector is often criticized for its lack of efficiency and quality.When the construction industry is compared to the rest of the domestic manufacturing industry, the general conclusions of the industry’s low efficiency is confirmed. The purpose has been to clarify why there is no sustainable building, despite the well-developed technology that now is available. The report also exam
Background The fierce competition in the telecom industry makes operators heavily invest in acquiring new customers. This is most often done with marketing campaigns and subsidies of handsets. But to be truly profitable, it is crucial not only to attract new customers, but also to make sure they retain with the company for as long time as possible. This turns the mobile operators’ attention to cus
This thesis investigates how cooperative membership impacts on the well-being of the individual. The case of the umbrella cooperative El Ceibo, operating in Bolivia, is investigated. Organizations such as the UN, the World Bank, and the ILO have high hopes for agricultural cooperatives as partners in the struggle for rural development. However, there is a lack of empirical studies investigating th
In the E. ON sponsored research project, Distibution LABoratory, at the Department of Industrial Electrical Engineering and Automation at LTH the impact of the increased move towards use of cables in the Swedish distribution grid is examined. The project also built a model of a small distribution grid. The model was used to simulate a Petersen coil earthed grid system. Petersen coil earthing lower
Purpose: The purpose is to explore a potential adoption of RFID technology in Spanish oranges producers´ outbound flow of the grey RFID-tagged plastic pallets that are delivered to Swedish wholesalers. The exploration will be focus on aspects regarding RFID technology, like level of knowledge and awareness, the willingness to invest on it, the attitude of the companies regarding the adoption, the
Global demands for water continue to rise while at the same time, the availability of reliable water resources are deteriorating. As 70% of the world’s human consumption of water resources is directed towards agricultural production, the need to improve water use efficiency and sustainability in these areas is of utmost importance. In order to tackle these issues, the concept of “Integrated water
Quantication of cardiovascular flow and blood volumes are useful tools in diagnosing cardiovascular disease such as congenital heart defects and different kinds of valve leakage. Medical imaging techniques enables non-invasive analysis of anatomy and physiology. In order to perform flow quantification from medical image sequences, the boundaries of the vessels of interest are usually delineated ma
