Considers the problem of moving a container with liquid without too much slosh in an industrial packaging machine, There is no measurement of the slosh available in the machine to use for control, it is however possible to measure the slosh in a testbed. The problem is to determine the shape of the open loop acceleration reference that is programmed in the motion control system that controls the m
Popular Abstract in Swedish Det doktorandarbete som framläggs av Pawel Brühl handlar om flera aspekter av ett framgångsrikt genomfört bullerskyddsarbete i en stor svensk industri med mycket hög bullernivå (Volvos pressverk i Olofström). Man har genomfört ett program bestående av bullermätningar, bullerreduktion med flera metoder samt studium av automatiseringens konsekvenser. Arbetstagarna har fåtThe design and implementation of a hearing conservation programme in a heavy industry with high noise levels is described. Action was taken on several points, including noise measurements, noise reduction, education on hearing protector use, and audiometric monitoring. It was found that the noise at the plant has been greatly reduced during a period of 25 years. The reduction in noise was made pos

When thin sheets containing a crack is subjected to tensile loading in the direction perpendicular to the crack surface out of plane displacement will occur in areas surrounding the crack. By this the stress state in the vicinity of the crack tip is changed and leads to a weaker crack tip singularity than the r-1/2 by linear elastic fracture mechanics. During lab testing the buckling is artificial
Popular Abstract in Swedish Storbritannien beslutade sig 1968 för att lämna bakom sig sina koloniala intressen i Persiska gulfen senast 1971. Det brittiska beslutet ledde till att de arabiska gulfstaterna Kuwait, Bahrain, Saudiarabien, Qatar, Förenade Arabemiraten och Oman i sin tur började undersöka möjliga samarbetsformer för att möta en ny tids osäkerhet och hot. Ett stort problem efter det briWhen Britain decided, in 1968, to terminate its official colonial presence in the Persian (Arabian) Gulf as of 1971, this action prompted the Gulf Arab States (Kuwait, Bahrain, Saudi Arabia, Qatar, United Arab Emirates, and Oman) to start the search for a form of partnership that would bring them together to better cope with the insecurity and danger surrounding them and their regimes. A key probl
Since over ten years, the Pordenone Silent Film Festival hosts masterclasses in which renowned pianists every day teaches, discusses and play silent films together with two selected young pianists who in this way get an intensive week of training the art of accompanying films. The masterclasses are open to the participators of the festival, and in this article we become part of the audience in fol
Popular Abstract in Swedish Kognitiv funktion är ett samlingsbegrepp för minne och högre tankeprocceser. Nedgången i dessa verbala, logiskt-induktiva, spatiala och minnes funktioner ses både vid normalt åldrandet och sekundärt till demens, stroke och åldersrelaterad minnesstörning. Förändringar i dessa funktioner kan vara ett tidigt tecken på vaskulärt (kärl-relaterad) betingad sjukdom eller degenThe importance of early detection of brain changes during ageing has been recognised. Single photon emission computed tomography (SPECT) is a method used for estimation of cerebral blood flow (CBF) in clinical work and in research. The aim of thesis was to study CBF in demented and non-demented elderly persons with special reference to blood pressure changes. Elderly women with senile dementia of
Popular Abstract in Swedish Det är välkänt att patienter som har gjort ett suicidförsök löper en ökad risk att i framtiden ta sitt liv. I de flesta fall görs suicidförsök av individer som på något sätt är utsatta för stress. Stress kan orsakas av en psykisk eller fysisk sjukdom. Psykosociala faktorer, såsom en skilsmässa eller en annan ohållbar situation i hemmet eller på arbetet, kan också förorsA suicide attempt is the best known predictor of completed suicide. It has long been assumed that most suicide attempts are the results of stress. The aim of this thesis was to examine some stress related peptides and their relations to the hypothalamic pituitary adrenal (HPA) axis, diagnoses and temperament in a heterogeneous group of suicide attempters shortly after a suicide attempt and at foll
This case book has been compiled within the framework of Phase III of the programme on Regional Air Pollution in Developing Countries (RAPIDC) funded by the Swedish International Development Cooperation Agency (Sida) and coordinated by the Stockholm Environmental Institute (SEI). This work has been produced by the International Institute of Industrial Environmental Economics (IIIEE) at Lund Univer
Popular Abstract in Swedish Ser man bakåt i historien har människan alltid försökt reparera eller ersätta vävnader i kroppen vid skador. En av de äldsta rapporterna om användande av biomaterial är runt 4000 år gammalt. I detta fall användes linnefibrer som suturmaterial. Från början användes naturliga material som collagen, silke, hår, bomull och olika cellulosamaterial. Under senare hälften av 19The aim of the this thesis was surface modification of a biomedical polyurethane (PUR), Pellethane 2363-80AE*, to improve the biocompatibility. Surfaces modified by poly(ethylene oxide) (PEO) were prepared either by grafting PEO covalently at the PUR surface by a two-step reaction, or by using amphiphilic polymers containing PEO as the hydrophilic part. The amphiphilic polymers consisted of one co
Preface to the new Swedish translation of Friedrich Engel's The Origin of the Family, Private Property, and the State.
Primary osteoporosis in children often leads to vertebral fractures, but it remains unknown whether these fractures associate with changes in bone composition. This study aimed to determine the differences in bone composition in fracture‐prone children with and without vertebral fractures, as assessed by Fourier transform infrared spectroscopic imaging (FTIRI) and bone histomorphometry. Iliac cres
The thesis considers the effects of electron correlation by studying the two opposite limits of atoms in the ground state and atoms in strong laser pulses. Computational methods and theoretical approaches differ significantly due to the different physical processes that are studied in these two cases. The thesis has an introductory chapter with a brief discussion of the problem of describing elec
This chapter describes various kinds of artificial light sources of interest to the photobiologist (natural light is described in separate chapters), starting with incandescent lamps and their properties, and continuing with gas discharge lamps, flashlamps and lasers. After a section on light filters the chapter concludes with a treatment of monochromators, in which the mode of action of a grating
