A two-stage procedure for pretreatment of fast-growing willow with steam has been investigated. The first stage was performed at temperatures in the range 180°C to 220°C for times between 6 and 10 minutes while the second stage was performed at 220°C for 10 minutes. The fibrous material was washed between the two stages to remove the pentosans and thus increase the pentose yield. The pretreatment
I denna skrift ges en heltäckande beskrivning av de byggnadsfysikaliska förhållandena i konstruktioner med golv på mark. Olika fuktbelastningar och deras konsekvenser beskrivs i detalj. Stor vikt läggs vid att skapa förståelse för olika byggnadsfysikaliska samband, speciellt mellan värme och fukt. Vidare tillämpas fuktdimensioneringsmetodiken på tre noggrant beskrivna grundkonstruktioner
Efficacy of veno-right ventricular bypass as a total extracorporeal lung assistance was studied for a period of 24 hours in six healthy pigs with a mean weight of 60 kg. A covalently bonded heparin-coated extracorporeal membrane oxygenation system and a roller pump were used for the bypass. No local or systemic heparin was administered. The bypass was established with an open chest with two 28F ve
Popular Abstract in Swedish Avhandlingen består av fyra kapitel som behandlar olika aspekter av internationell handel och dess effekter på konkurrens och produktivitet. Särskilt behandlas effekterna av EU:s expansion och fördjupade integration. Första kapitlet använder den så kallade gravitationsmodellen för att analysera hur integrationsprocessen av de Central- och Östeuropeiska länderna i EU haThis thesis consists of four papers on trade, competition and productivity with particular emphasis on the effects of various aspects of the deepening and widening of the European Union. The first paper Trade Creation, Diversion and Displacement of the EU Enlargement Process provides an assessment of the effects of the EU enlargement process on trade. A new method of estimating the gravity model
PURPOSE. To compare a fundus image-analysis algorithm for automated detection of hemorrhages and microaneurysms with visual detection of retinopathy in patients with diabetes. METHODS. Four hundred fundus photographs (35-mm color transparencies) were obtained in 200 eyes of 100 patients with diabetes who were randomly selected from the Welsh Community Diabetic Retinopathy Study. A gold standard re
Ca2+ sensitization of smooth muscle contraction involves the small GTPase RhoA, inhibition of myosin light chain phosphatase (MLCP) and enhanced myosin regulatory light chain (LC20) phosphorylation. A potential effector of RhoA is Rho-associated kinase (ROK). The role of ROK in Ca2+ sensitization was investigated in guinea-pig ileum. Contraction of permeabilized muscle strips induced by GTPgammaS
Real world systems are normally considered as hierarchically organized, for example, we see those as hierarchies of systems including subsystems. Examples on this can be seen in organizations where people act in environments and carry within themselves their own internal subsystem of thinking processes. Another example relates to robotics where robots may be seen as hierarchical constructions, bot
Simultaneous measurements of early flame speed and local measurements of the major parameters controlling the process are presented. The early flame growth rate was captured with heat release analysis of the cylinder pressure. The local concentration of fuel or residual gas were measured with laser induced fluorescence (LIF) on isooctane/3-pentanone or water. Local velocity measurements were perfo
Popular Abstract in Swedish Schizofreni är en kronisk och handikappande sjukdom som karakteriseras av allvarliga men fluktuerande symtom, med återkommande akuta episoder. Sjukdomen är förknippad med reducerad kognitiv och social funktionsförmåga. Patienterna vilka i regel insjuknar i unga år, bibehåller vanligtvis kvarstående restsymtom och därmed associerade stigma fram till ålderdomen. Det överObjective: To explore the long-term course and to study factors of potential relevance for the treatment and rehabilitation process of patients with schizophrenia and schizophrenia-like disorders. Specific issues concerned cognitive reduction, tardive dyskinesia (TD), prolactin-induced side effects, remission and lack of insight. Method: A naturalistic multicenter study of 225 patients, diagnosed

BACKGROUND: Death of smooth muscle cells in the atherosclerotic plaques makes the plaques more prone to rupture, which can initiate an acute ischemic event. The development of atherosclerosis includes the migration of immune cells e.g. monocytes/macrophages and T lymphocytes into the lesions. Immune cells can release antimicrobial peptides. One of these, human cathelicidin antimicrobial peptide hC
In the article a simulation model of pricing behaviour on the gasoline market in Sweden is reported. First a brief review of price-changes during a historical period is provided. Next the model is presented in three steps with increasing level of detail for each step. The companies in the model are assumed to have three goals but only one variable for action
In this paper, the further development of a silicon flowthrough microdispenser is described. Previously reported designs of the dispenser used bimorph, and later multilayered, piezoelectric actuator elements for the generation of droplets. The introduction of a multilayered actuator significantly reduced the voltage amplitude needed to dispense droplets. Dispenser properties relevant for chemical
OBJECTIVE. Our goal was to investigate whether outcome in extremely low birth weight infants changes over time in Finland. PATIENTS AND METHODS. All infants with a birth weight < 1000 g born in Finland in 1996 - 1997 and 1999 - 2000 were included in the study. Perinatal and follow-up data were collected in a national extremely low birth weight infant research register. Data concerning cerebral pal
Pseudomonas aeruginosa colonizes 20-30% of all venous leg ulcers. Hypothetically, P. aeraginosa could release proteases and cytotoxic substances in the environment of chronic ulcers, thus negatively affecting the wound-healing activity in this patient group. Here we show that P. aeruginosa isolates from leg ulcers exhibit a highly variable expression of the proteinases elastase and alkaline protei
The high-spin structure of Er-157 has been greatly expanded using the Gammasphere spectrometer to investigate the Cd-114(Ca-48,5n) reaction at 215 MeV. Many new transitions have been placed in a greatly augmented level scheme up to spin 40h with many collective rotational sequences established. With increasing angular momentum, this nucleus undergoes a Coriolis-induced shape transition from a defo
Popular Abstract in Swedish I september 1989 kom det till kanadensiska mi’kmaqindianers kännedom att ett enormt granitbrott (ett av de tre största i världen) planerades att öppnas vid Kellys Mountain på ön Cape Breton i östra Kanada. Mi’kmaqtraditionalister organiserade genast en fredlig trumceremoni på berget och en talesman deklarerade att det planerade granitbrottet var en förolämpning mot bådeThis dissertation seeks to explore historical changes in the lifeworld of the Mi’kmaq Indians of Eastern Canada. The Mi’kmaq culture hero Kluskap here serves as a key persona in discussing issues such as traditions, changing conceptions of land, and human-environmental relations. In order not to depict Mi’kmaq culture as timeless, two important periods in its history are examined. The first study
