Kvinnor är sjukskrivna och förtidspensionerade i högre grad än män. En orsak till kvinnors höga sjuktal är en dåligt fungerande sjukförsäkring i kombination med en problematisk arbetsmarknad.

There is an increasing challenge for chemical industry and research institutions to find cost-efficient and environmentally sound methods of converting natural resources into fuels chemicals and energy. Catalysts are essential to these processes and the Catalysis Specialist Periodical Report series serves to highlight major developments in this area. This series provides systematic and detailed re

Popular Abstract in Swedish Den här avhandlingen behandlar hur fettdroppar i mjölk slås sönder i en mjölkhomogenisator. Mekanismerna bakom sönderslagningen har analyserats genom uppmätning av flödesfältet i spalten samt genom att fotografera dropparna, när de slås sönder. För att möjliggöra mätning och fotografering har två skalmodeller av en homogenisator tagits fram. En fullskalemodell, vilken The overall aim of this project was to investigate the drop break-up process in milk homogenisers. This was done by measurements and calculations of the flow fields in the gap region and by visualisation of drops being broken up. To make visualisation and measurements possible, two scale models of a homogeniser gap were developed. The full-scale model was a direct copy of the gap in a production-

To optimize productivity and working-life quality, it is important to understand and utilise the connections between productivity and working environment. Culture and the state of the market may affect the strength of these connections. However, in order to ensure flexibility and quality in products and services, it may be useful to have motivated, skilled and responsible coworkers at all levels.

The article is based on a pilot study of the stories of Swedish patients having had a kidney transplant abroad. Our focus is on how people who have been transplanted abroad talk about and handles the dilemma that may arise due to the transplantation trips.

Jason 85 ls är en testbildsgenerator konstruerad för de färgbildsplottrar som framtagits vid institutionen. Den är uppbyggd kring Intels mikrodatorkretsar med CPU 8085 och DMA-kanal 8257-5. Minnet består av 1.5k RAM-minne och 3k PROM-minne. Testbildsgeneratorn simulerar bandstationen som normalt arbetar mot plottern och ger denna data för uppbyggandet av bilden. Testbildsgeneratorn kan generera f

The dynamic instability and related problems when turning high chromium cast iron (HCCI) with two polycrystalline cubic boron nitride (PCBN) tools in wide range of cutting speeds and feed rates were studied in the article. The tool wear mechanisms and specifics for both tools as a main criterion of appearance of process instability were investigated. In spite of the chatter-like surface of machine

The first part of this paper aims at identifying the timing of famines in the Nordic countries since the middle ages. This is done by using qualitative famine reports from the literature since quantitative data on famines are scarce or non-existent, at least before the early modern period. We supplement the reports with climate data and price data. Our survey indicates that widespread famine was a

Ternary isothermal (25°C) polyoxyalkylene triblock block copolymer ((EO)x(PO)y(EO)x where x is the number of ethylene oxide, EO, segments and y is the number of propylene oxide, PO, segments) systems with water and p-xylene as selective solvents for the PEO and PPO blocks, respectively, were chosen as study systems in this thesis as these ternary systems are good model systems for the self-assembl

Popular Abstract in Swedish Under det senaste årtiondet har förekomsten av läkemedel i miljön rönt stor uppmärksamhet. Studier har visat att flera läkemedel hittats i sjöar och vattendrag och kan förorsaka negativa effekter hos vattenlevande organismer. Den i särklass största vägen via vilken läkemedel når miljön är avloppsreningsverk. Efter att vi ätit ett läkemedel kommer kroppen också att utsönThis thesis addresses the application of hollow fiber liquid phase microextraction as a simple, efficient and environmentally friendly tool to study the fate of four common anti-inflammatory drugs (ketoprofen, naproxen, diclofenac and ibuprofen) during wastewater treatment. Initial experiments verified that this technique is applicable on aqueous as well as suspensions of solid samples, thus great

Stability in presence of (possibly varying)time-delays in a control loopconsisting of a continuous-time plant and a discrete-time controlleris studied.A simple stability criterion is developed—agraphical test in a Bode plot of the closed loop system. The graphicaltest makes it very easy to design the controller for time-delayrobustness.
