Popular Abstract in Swedish Olyckor i järnvägssektorn kan ge upphov till katastrofala konsekvenser. I första hand kan människors liv och hälsa drabbas, men allvarliga konsekvenser kan även uppstå för samhället i stort. Detta beror på att järnvägssystemet, liksom en rad andra infrastruktursystem är väsentliga för att vårt moderna samhälle ska fungera. Under de senaste decennierna har dessa system bIn recent decades, the Swedish railway system has faced substantial deregulations. As a result, management of risk is often carried out in settings involving multiple stakeholders having various roles, mandates, and viewpoints on risk, and where no single stakeholder has the superior authority. In order to manage risks in this type of multi-actor setting, the traditional elements of risk assessmen

Previously not shown this study support that mfVEP is an indicator of optic nerve neuropathy in diabetic patients and there could be a correlation between the optic nerve dysfunction and diabetic poly neuropathy. The early optic nerve involvement might explain some of the visual complain in this group of diabetic patients.

Sequential Monte Carlo (SMC) methods have demonstrated a strong potential for inference on the state variables in Bayesian dynamic models. In this context, it is also often needed to calibrate model parameters. To do so, we consider block maximum likelihood estimation based either on EM (Expectation-Maximization) or gradient methods. In this approach, the key ingredient is the computation of smoot

Laser-induced fluorescence (LIF) for in vivo point monitoring and fluorescence microscopy incorporating a CCD camera were used to study the fluorescence distribution of 5-aminolevulinic acid (ALA)-induced protoporphyrin IX (PpIX) in tumours. Fluorescence in a chemically induced adenocarcinoma in the liver of rats and in an aggressive basal cell carcinoma in a patient were studied after intravenous

Context: Long-term data are missing in GH-treated acute lymphoblastic leukemia (ALL) patients. GH therapy may result in poorer outcome regarding cardiovascular (CV) and particularly cardiac effects than in patients with hypothalamic-pituitary disease. Objective: Our objective was to evaluate GH therapy on CV risk, cardiac function, physical activity, and quality of life in ALL patients treated wit

This longitudinal study examines the relationship between family and friend social support, health, and life satisfaction for a single cohort of eighty-year-old persons living in Lund, Sweden. Results indicate that participants who remained in the study are healthier and score higher on life satisfaction when compared with those who either drop-out or die prior to age eighty-three. Even though wel

Natural radiative lifetimes of eight levels in Tm m were measured with the time-resolved laser-induced fluorescence (LIF) technique. Free doubly ionized thulium ions were obtained in a laser-produced plasma. Three even-parity levels were excited from the ground state with one-photon excitation, using a laser system generating pulses of 1 ns duration. Five odd-parity levels were excited from the gr

Studien utgör en del i ett tvärvetenskapligt forskningsprogram, ¯Effekthushållning i byggnader¯, genomfört vid Lunds Universitet. Den här studien har fokuserat energianvändning i bostäder ur ett kulturanalytiskt perspektiv. Detta har inneburit ett åskådliggörande av möten mellan bransch och brukare på den omreglerade elmarknaden. Här har vardagslivet varit en metodisk och analytisk utgångspunkt fö

B-cell development into antibody producing cells is a complex process that relies on the tightly controlled production of hundreds of genes and proteins. A B-cell is activated through the B-cell receptor (BCR) and this activation is modified by different co-stimulatory or inhibitory co-receptors. The concerted action of signals from BCR and from co-receptors decides the fate of the B-cells. The ma
