Popular Abstract in Swedish I »operatörens blick« beskrivs ett projekt där möjligheter för IT-stöd i erfarenhetsöverföring undersökts inom ett område där konfrontationen mellan datorisering och yrkeskunnande är särskilt tydlig - operatörsarbete i processindustrin. Driftsstörningar av olika omfattning är ett kontinuerligt inslag i operatörsarbetet och snabba förändringar i risknivå är en central deStudies in process control automation show that manual control skills are important in handling situations where the automatic control system fails. The fact that these skills are particularly difficult to maintain and develop in automated production environments is usually described as one of the ironies of automation. This work explores new roles for computer support in developing and maintainin

Knockout of caspase-8, a cysteine protease that participates in the signaling for cell death by receptors of the TNF/nerve growth factor family, is lethal to mice in utero. To explore tissue-specific roles of this enzyme, we established its conditional knockout using the Cre/loxP recombination system. Consistent with its role in cell death induction, deletion of caspase-8 in hepatocytes protected

Streptococcus pneumoniae infections remain a major cause of morbidity and mortality worldwide. Therefore a detailed understanding and characterization of the mechanism of host cell colonization and dissemination is critical in order to gain control over this versatile pathogen. Here we identified a novel 72 kDa pneumococcal protein endopeptidase O (PepO), as a plasminogen and fibronectin binding p

Finger jointing of unseasoned Norway Spruce was studied with respect to tensile strength, adhesive penetration and durability. Finger joints were manufactured with 1) unseasoned wood and one component polyurethane (PUR) adhesive, 2) dried wood and PUR adhesive and 3) dried wood and phenol resorcinol formaldehyde (PRF) adhesive. Two levels of wood density were used. The tensile strength of the f

Underdrawings and pentimenti-typically revealed through x-ray imaging and infrared reflectography-comprise important evidence about the intermediate states of an artwork and thus the working methods of its creator.(1) To this end, Shahram, Stork and Donoho introduced the De-pict algorithm, which recovers layers of brush strokes in paintings with open brush work where several layers are partially v

Under det senaste decenniet har en rad kvinnliga författare kommit att bli framgångsrika inom den svenska deckargenren. Det vanliga epitetet ”deckardrottning” vittnar om att framgången står i relation till en offentlig och medialiserad version av författarskapen, där den kvinnliga erfarenheten spelar en betydande roll. Liza Marklund och Camilla Läckberg är de två bland dessa författarskap som skap

Streptococcus pneumoniae (pneumococcus) is a pathogen that causes severe local and life-threatening invasive diseases, which are associated with high mortality rates. Pneumococci have evolved several strategies to evade the host immune system, including complement to disseminate and to survive in various host niches. Thus, pneumococci bind complement inhibitors such as C4b-binding protein (C4BP) a

This study deals with physical education (PE) in secondary school. The purpose of the study is to analyze the relationship between PE in secondary schools and leisure time sports. Questions were directed towards discovering what PE teachers recognise as valuable in their teaching, and how physical education is related to factors that characterize the field of sports. The teaching practice of Physi

PURPOSE: To compare the clinical outcome after carpal tunnel release in diabetic and nondiabetic patients. METHODS: We evaluated a prospective, consecutive series of 35 diabetic patients (median age, 54 years; 15 with type 1 and 20 with type 2 diabetes) with carpal tunnel syndrome, who were age- and gender-matched with 31 nondiabetic patients (median age, 51 years) having idiopathic carpal tunnel

We have addressed the importance of B cell tolerance to collagen type II, a matrix protein, which is a target in rheumatoid arthritis (RA) and its mouse models. We generated a germline-encoded anti-collagen type II (CII) IgH replacement anti-C1 B cell mouse strain (ACB) to investigate how B cell tolerance to CII, a matrix protein, is subverted and to further understand pathogenesis of RA. Phenotyp

Anomi är ett centralt rättssociologiskt begrepp introducerat av Émile Durkheim (1858-1917) som beskriver ett tillstånd av oklarhet och normlöshet som överförs på individen vilket får denne att känna otillfredsställelse. Identifieringen av anomi indikerar rättsliga förändringsprocesser och tydliggör samtidens rättskultur när mönster bryts. Kränkningsersättning, s.k. rent ideellt skadestånd, som akt

The antibody response to the envelope proteins of hepatitis C virus (HCV) may play an important role in controlling the infection. To allow molecular analyses of protective antibodies, we isolated human monoclonal antibodies to the E2 envelope glycoprotein of HCV from a combinatorial Fab library established from bone marrow of a chronically HCV-infected patient. Anti-E2 reactive clones were select

A central problem in computer vision is to reconstruct the three-dimensional structure of a scene from a set of two-dimensional images. Traditionally this is done by extracting a set of characteristic points in the scene and to compute a reconstruction of these points. In this thesis we propose a novel method that allows reconstruction of a wider class of objects, including curves and surfaces. As

A new algorithm, based on embedding phase space, to detect the P-wave characteristic points of an ECG signal is reported in this paper. The multi-lead ECG is transformed into points of an embedding phase space where similar ECG morphologies are converted into phase space points that are close using some distance measure. The algorithm is robust with respect to the type of selected characteristic p

The dissertation is confined to the formal work of the boards of the parent companies as recorded in the approved minutes of meetings at Alfa Laval AB, Atlas Copco AB and Kockums Mekaniska Verkstads AB and is based on the Companies Law applying in Sweden since 1848. The study covers the time from the establishment of the joint stock company up to the ordinary general meeting of 1980 (1979 in the c

Rationale, aims and objectives The aim of this study was to compare acute hospital utilization and costs for patients with refractory angina pectoris undergoing spinal cord stimulation (SCS) versus enhanced external counterpulsation (EECP). Method Seventy-three persons were included in this register study. The acute hospital utilization and costs for SCS and EECP were followed over a period from 1

Evaluated the importance of ultrasound to women’s thoughts about their unborn child. 10 first-time mothers (ages 22 – 33 years) with normal pregnancies were interviewed approxi¬mately 1 week before and 1 week after their first ultrasound screening. Analysis of the interviews was conducted using the techniques of grounded theory. The results show that ultrasound was of great importance for increasi

Hydrides GdGaHx were obtained by exposing the Zintl phase GdGa with the CrB structure to a hydrogen atmosphere at pressures from 1.5 to 50 bar and temperatures from 50 to 500 °C. Structural analysis by powder X-ray diffraction suggests that conditions with hydrogen pressures in a range between 15 and 50 bar and temperatures below 500 °C afford a uniform hydride phase with the NdGaH1.66 structure (

Retinal ischemia arises from circulatory failure. As the retinal blood vessels are key organs in circulatory failure, our aim was to study the retinal vasculature separately from the neuroretina to elucidate the role of hypoxia-inducible factor (HIF) 1α and 1β and vascular endothelial growth factor (VEGF) in retinal ischemia. Retinal ischemia was induced in porcine eyes by applying an intraocular
