Inventering av insekter i Benestads backar och Hagestad naturreservat

The two nature reserves Benestads backar and Hagestad in Scania, southernmost Sweden, were surveyed for insect diversity during 2011 and 2012. Because current management plans for both reserves include a size expansion to increase the protective status also of adjacent areas, the aim of this survey was to derive a measure of current insect diversity in both reserves. These estimates can then be us

This contribution deals with the topic of transnationalism as it has developed in the humanities in the last two decades. The starting point for the reflections is the author's experiences over the course of two research projects in the years 1996 to 2003. "Musik baut Brücken?" seeks to highlight some of the definitions and difficulties of "transnationalism" which have become obvious in several de

Flexible Force-Vision Control for Surface Following using Multiple Cameras

A flexible method for six-degree-of-freedom combined vision/force control for interaction with a stiff uncalibrated environment is presented. An edge-based rigidbody tracker is used in an observer-based controller, and combined with a six-degree-of-freedom force- or impedance controller. The effect of error sources such as image space measurement noise and calibration errors are considered. Finall

Protection against cold in prehospital care — thermal insulation properties of blankets and rescue bags in different wind conditions

Introduction: In a cold,wet, or windy environment, cold exposure can be considerable for an injured or ill person. The subsequent autonomous stress response initially will increase circulatory and respiratory demands, and as body core temperature declines, the patient’s condition might deteriorate. Therefore, the application of adequate insulation to reduce cold exposure and prevent body core cool

Methods to Generate Size- and Composition Controlled Aerosol Nanoparticles

Popular Abstract in Swedish Den här avhandlingen beskriver olika experimentella metoder att framställa nanopartiklar med kontroll över storlek och sammansättning. En nanopartikel är en partikel som är mindre än 100 nanometer (1 nm är en miljondels millimeter). Utmaningen ligger i att partiklarna är såpass små. En nanopartikel förhåller sig ungefär storleksmässigt till en tennisboll som en tennisboThis thesis describes experiments performed using different methods to produce aerosol nanoparticles with control over size and composition. The process included differential mobility analyzers (DMAs) as size-selecting instruments and tube furnaces for particle synthesis. A method to estimate the degradation of the DMA performance from the ideal case for individual DMAs was proposed and tested ex

Physiology and Pharmacology of C-fibres in the rabbit eye

C-fibre neuropeptides, such as tachykinins and calcitonin-gene related peptide (CGRP), play an important role in neurogenic inflammation. The present work deals with five different aspects of the physiology and pharmacology of C-fibres. 1) Tachykinin receptor antagonists of peptide and non-peptide nature have been employed to identify the tachykinin receptors of the rabbit iris as NK1 and NK3 type

A Braided View of a Knotty Story

Periodic orbits of 3-d dynamical systems admitting a Poincaré section can be described as braids. This characterisation can be transported to the Poincaré section and Poincaré map, resulting in the braid type. Information from braid types allows to estimate bounds for the topological entropy of the map while revealing detailed orbit information from the original system, such as the orbits tha

Trick or treatment. Brokering biotech.

This chapter focuses on technology-brokers and inventors who operate in a medical context. It aims to discuss how relationships between the actors involved affect the possibility of transforming innovations into consumables, and to describe the kind of social work needed to successfully make this transformation. The chapter explores some of those tricks by using the concept 'net work' when discuss

The positive impact of negative role models

The attitude of teachers towards students can vary substantially in relation to different factors, such as educational background, pedagogical training, teaching methods, etc. In this paper, we explore the impact of negative role-models on future teaching. In particular, past experiences of teachers as students as well as the contextual influence of other teachers on their future teaching has been
