Monitoring and influencing safety through safety culture

Organizations need to make sure that their level of safety is acceptable. Therefore it is important to know which factors contribute to the level of safety and how to monitor and improve these factors. One method used today to evaluate the level of safety in organizations is safety culture measurements. In different contexts, different models of safety culture are used. Safety culture is often con

Tumor Necrosis Factor-alpha as a target cytokine in vascular disease

Popular Abstract in Swedish Åderförkalkning, eller rättare sagt åderförfettning är den vanligaste dödsorsakerna i västvärlden och frekvensen ökar samtidigt som symptomen går nedåt i åldrarna. Därför är det mycket viktigt för oss att få reda på vad som grundlägger sjukdomen, hur vi skall kunna motverka dess uppkomst och hur vi skall kunna bota den. Vi vet inte med säkerhet varför en individ drabbasInflammation plays an important role in atherosclerosis. One of the most potent pro-inflammatory cytokines is tumor necrosis factor-alpha (TNF-a), a cytokine identified to have a pathogenic role in chronic inflammatory diseases such as rheumatoid arthritis (RA). The major objectives of this investigation was to establish a role for TNF-a in the development of atherosclerosis and neointimal formati

Detection and Classification of Liquid Explosives using NMR

In this work, we present a novel method for non-invasive identification of liquids, for instance to allow for the detection of liquid explosives at airports or border controls. The approach is based on a nuclear magnetic resonance technique with an inhomogeneous magnetic field, forming estimates of the liquid's spin-spin relaxation time, T2, and diffusion constant, D, thereby allowing for a unique

The van der Waals interaction between colloidal particles and its molecular interpretation

We discuss the relation between a description of the van der Waals interaction between colloidal partic es based on a molecular picture of matter with the Lifshitz description based on quantum electrodynamics. The main observations are as follows: (i) Starting from the Lifshitz description one can derive the exact Hamaker result for the dispersion interaction by applying the Clausius-Mossotti form

Coaching och handledning av grupper - inom universitets- och högskoleutbildning (e-bok)

Denna bok handlar om ett förändringsprojekt vid Lunds universitet som syftade till att förkorta studietiderna utan att kandidat- och magisteruppsatsernas vetenskapliga kvalitet påverkades negativt. Det omedelbara resultatet blev att andelen uppsatser som blev färdiga inom föreskriven tidsram ökade från under 10 % till över 50 % samtidigt som deras vetenskapliga kvalitet inte försämrades. I boken b

Polarizabilities and Fundamental Bounds on Antennas

Fundamental bounds on single-port antennas and on array antennas have been shown to depend on the electric and magnetic polarizability tensors. We show four such cases and compare how the polarizabilities enter into the bounds. One of the critical items in using these bounds is the determination of the polarizabilities. We here review methods to obtain the polarizabilities, and discuss some of the

Selective immunolesion of cholinergic neurons leads to long-term changes in 5-HT2A receptor levels in hippocampus and frontal cortex.

Although loss of cholinergic neurons in the basal forebrain is considered a key initial feature in Alzheimer's disease (AD), changes in other transmitter systems, including serotonin and 5-HT2A receptors, are also associated with early AD. The aim of this study was to investigate whether elimination of the cholinergic neurons in the basal forebrain directly affects 5-HT2A receptor levels. For this
