Redovisning och ansvar - det ålagda och det självpåtagna

Att kunna redovisa resultat ser vi i dagens samhälle som en självklar del av en organisations verksamhet. Privata profitdrivna företag liksom även alltmer offentliga organisationer styrs idag genom en marknadslogik som bland annat bygger på kontraktsbaserade uppdrag vilka förutsätter en granskning av hur de offentliga medlen används. Liknande krav på att utvärdera resultat och framgång blir i allt

Snails have stronger indirect positive effects on submerged macrophyte growth attributes than zooplankton

Phytoplankton and epiphyton often compete with submerged macrophytes. Grazing by zooplankton and/or epiphyton grazers should promote an indirect positive effect on submerged macrophyte growth rate. Hence, we mimicked shallow lakes conditions in mesocosms using a factorial design to evaluate the indirect effects of no grazers, zooplankton, snails or both grazers on macrophyte growth attributes. Aft

Spatial Statistical Modeling of Insurance Risk An epidemiologist approach to car insurance

Spatial models, such as the Besag, York and Mollie (BYM)model, have long been used in epidemiology and disease mapping. A commonproblem in these subjects is the modelling of number of disease eventsper region; here the BYM models provides a holistic framework for bothcovariates and dependencies between regions.We use these tools to assess the relative insurance risk associated withthe policyholderSpatial models, such as the Besag, York and Mollie (BYM)model, have long been used in epidemiology and disease mapping.

A Sustainable Century?: Genuine Savings in Developing and Developed Countries, 1900-2000

This chapter traces the long-run development of Genuine Savings (GS) using a panel of eleven countries during the twentieth century. This panel covers a number of developed countries (Great Britain, Germany,Switzerland, France, the US, and Australia) as well as a set of resource-abundant countries in Latin America(Argentina, Brazil, Chile, Colombia, and Mexico). These countries represent approxima

Application of iterative robust model-based optimal experimental design for the calibration of biocatalytic models

The aim of model calibration is to estimate unique parameter values from available experimental data, here applied to a biocatalytic process. The traditional approach of first gathering data followed by performing a model calibration is inefficient, since the information gathered during experimentation is not actively used to optimize the experimental design. By applying an iterative robust model-

Counseling for childbirth fear - a national survey

Background: Counseling by experienced midwives is offered to women with childbirth fear in most obstetric clinics in Sweden, but information about the content of such counseling is lacking. Aim: To study comprehensiveness, content and organization of the midwife-led counseling for childbirth fear in all obstetric clinics in Sweden. Methods: In this cross-sectional study, data were collected using

Tubular repair of the median nerve in the human forearm. Preliminary findings

Transected median nerves in the forearm of two male patients, 12 and 21 years of age, were treated with a chamber technique leaving a 3 to 5 mm gap between the nerve ends. The nerve ends were enclosed in a silicone tube of such a dimension that would not cause compression of the nerve. Post-operative examination including sensory evaluation and assessment of muscle contraction force was carried ou

Characterization of neurotrophic activity in the silicone-chamber model for nerve regeneration

In the present study, the authors reevaluated the temporal course and properties of neurotrophic activities present in the fluid accumulating in the silicone-chamber model for nerve regeneration. The fluid collected from silicone chambers was tested in four different dissociated neuronal cell cultures. Furthermore, the activity of the chamber fluid was examined, using a cell blot technique. There

Fibroblast growth factor effects on peripheral nerve regeneration in a silicone chamber model

We have developed a silicone nerve regeneration chamber that is partitioned into two compartments by a strip of nitrocellulose paper. The modified two-compartment chamber allows the investigation of the effects on rat sciatic nerve regeneration of trophic or growth factors that are initially bound to the nitrocellulose partition. In this study we compared the effects of untreated nitrocellulose, a

Effects of epidural and intrathecal application of collagenase in the lumbar spine : an experimental study in rabbits

An experimental model is described in which collagenase in different concentrations and volumes were applied epidurally or intrathecally in the rabbit lumbar spine. This made it possible to study the tissue effects in a situation similar to that of collagenase leaking from a disc or accidental epidural or intrathecal injection at chemonucleolysis. Epidurally applied collagenase, in higher concentr

Effects of nerve compression or ischaemia on conduction properties of myelinated and non-myelinated nerve fibres. An experimental study in the rabbit common peroneal nerve

Compound action potentials of both myelinated (A) and non-myelinated (C) fibres in the common peroneal nerve of rabbits were studied during and after acute, graded compression of the nerve at 200 or 400 mmHg applied for 2 h or during ischaemia created by nitrogen inhalation or aortic occlusion. Compression of the nerve at 200 mmHg blocked the AI component (large myelinated fibres) after about 23 m

Hydration properties of briquetted wheat straw biomass feedstock

Biomass densification elevates the bulk density of the biomass, providing assistance in biomass handling, transportation, and storage. However, the density and the chemical/physical properties of the lignocellulosic biomass are affected. This study examined the changes introduced by a briquetting process with the aim of subsequent processing for 2nd generation bioethanol production.
