Programmes driving ELT design are discussed. The nature and evolution of circum-stellar shells and planetary discs are attractive, while the small angular sizes place basic properties, asymmetry and warps, beyond VLT capability. An ELT is neeed to reveal the conversion processes shell - disc - planets, planetary systems, Earth-like planets, habitability and life signatures. Formation and evolution
Normal ageing in men is associated with a physiological decline in testosterone levels, but adverse environmental or psychosocial factors may also impair testosterone secretion and cause secondary biological changes. In a number of observational or experimental studies in both animals and man, it has been possible to study the influences on gonadal function of stressful life situations. To underst
Transplantation of progenitor cells to the CNS has shown promise in neuronal and glial replacement and as a means of rescuing host neurons from apoptosis. Here we examined the effect of progenitor grafts on neurite extension in the degenerating retina of rd1 ( retinal degeneration 1) mice. Transplantation of retinal progenitor cells induced increased matrix metalloproteinase-2( MMP2) secretion, pa
Popular Abstract in Swedish En god näringstillförsel är viktigt för att ett barn ska växa och utvecklas tillfredställande. De första 2-3 åren innebär en kraftig tillväxt och optimalt kostintag är därför extra viktigt under denna perioden. Barnets vikt tredubblas först året och längden ökar med 50 %. Hjärnan har en kraftig tillväxt de första 3 åren. Således är näringsbehoven relativt sett störst deThe overall aim of this thesis was to describe the prevalence of iron deficiency (ID) and factors influencing iron status and iron intake among otherwise healthy children. The specific aim in paper I+II was to describe the prevalence of ID among 2 ½-year-old children in relation to intake of cow's milk and follow-on formula. The design in the first two papers were cross-sectional and 367 2 ½-year-
In this paper, we discuss the internet low bit rate codec (iLBC) with an emphesis on the frame-independent longterm prediction. The frame-independent long-term prediction is a method to exploit pitch-lag correlations in the encoding of speech without suffering multiple-frame speech degradation in connection with transmission loss. We present mean opinion scores for the iLBC codec and show by means
The thesis consists of an introduction and the following four papers: Paper I: Using resultants for SAGBI basis verification in the univariate polynomial ring. Authors: Anna Torstensson, Victor Ufnarovski and Hans Öfverbeck. Abstract: A resultant-type identity for univariate polynomials is proved and used to characterise SAGBI bases of subalgebras generated by two polynomials. A new equivalent
This study describes frequencies and associations between eating difficulties, assisted eating and nutritional status in 520 elderly patients in hospital rehabilitation. Eating difficulties were observed during a meal and nutritional status was assessed with Subjective Global Assessment form. Eighty-two percent of patients had one or more eating difficulties, 36% had assisted eating and 46% malnut
Induction of the mitochondrial permeability transition (MPT) has been implicated in cellular apoptosis and in ischemia-reperfusion injury. During MPT, a channel in the inner mitochondrial membrane, the mitochondrial megachannel, opens and causes isolated mitochondria to swell. MPT and mitochondrial swelling is inhibited by cyclosporin A (CsA), which may also inhibit apoptosis in some cells. Treatm
This paper describes the extraction of information on lethal events from the Swedish version of Wikipedia. The information searched includes the persons’ cause of death, origin, and profession. We carried out the extraction using a processing pipeline of available tools for Swedish including a part-of-speech tagger, a dependency parser, and manually-written extraction rules. We also extracted stru
En av de mest grundläggande principerna inom aktiebolagsrätten och en stark bidragande faktor till dess popularitet återfinns i 1 kap. 3 § ABL, dvs. aktieägare är som huvudregel inte personligt ansvariga för bolagets förpliktelser. Till varje huvudregel finns undantag och så även här. I Sverige har det diskuterats om aktieägare trotsallt ska kunna hållas ansvariga för bolagets förpliktelser genom One of the most fundamental principles of company law and a strong contributing factor to its popularity can be found in chapter 1. article 3 in the Swedish Companies Act, i.e. shareholders, as a general principle, are not personally responsibility for the debts or actions of a corporation. To every general principle exists exceptions, which applies here as well. In Sweden, the question has been r
Under de senaste åren har ett antal fall av hets till självmord på internet och sociala medier uppmärksammats såväl nationellt som internationellt. Under våren år 2018 rapporterade medier i Sverige om ett svenskt fall där en polisman givit en ung kvinna instruktioner via sms om hur hon bäst skulle begå självmord. Eftersom självmord och självmordsförsök inte är kriminaliserat blir medverkansreglernIn recent years, a number of cases of incitement to suicide on the internet and social media have been highlighted both nationally and internationally. In spring 2018, media reported on a Swedish case where a policeman gave a young woman instructions through text messages about how to best commit suicide. Since suicide and suicide attempts are not criminalized, the rules of complicity are not appl
Bakgrund: Informationsteknologin har genomgått flera dramatiska förändringar under åren. Den senaste stora förändringen var uppkomsten av Internet. Internet skapade billiga och effektiva sätt att koordinera och utbyta information. Det skapade inte bara möjligheter utan även frågor om hur företag borde använda dessa teknologier för att skapa lönsamhet. Ett sätt för företag att svara på des
A flattening filter free x-ray beam mode was added to an Elekta linear accelerator by placing a flat copper plate in the filter carousel and recalibrating the electron steering servo, gun servo and dosimetry system. Machine configurations were saved onto a separate hard disk in order to remain separate from the clinical configuration. Profile measurements with a Schuster BMS diode array show that
Czechoslovak productive efficiency of the iron and steel sector fluctuated below the energy efficiency frontier. Until early 1970s, the country's iron sector was one of the least efficient ones in our sample. It was, however, during the decades of 1970s and 1980s that efficiency measures were adopted and the energy efficiency of the Czechoslovak iron and steel sector increased significantly to, de
