Konsten att flyga har uppstått fyra gånger under evolutionens gång: hos fåglarna, fladdermössen, insekterna och de nu utdöda flygödlorna. En av dessa grupper – insekterna – har varit otroligt framgångsrik: insekter står för ungefär 80% av världens arter. Troligtvis har förmågan att flyga bidragit till deras framgång. Men trots att det finns många fördelar med att kunna flyga – man kan till exempel fly frAerodynamic theory states that the power required to fly is related to flight speed with a ∪-shaped curve. This has been shown in vertebrates, but insects have been proposed to have a flat, or J-shaped power curve. This means that hovering – flying at zero speed – is energy-efficient, which would explain why it is a relatively common flight mode in insects. In this thesis I show that some insects do, in

Objective: Our report describes clinical, genetic, and biochemical features of participants with a molecularly confirmed congenital disorder of glycosylation (CDG) enrolled in the Frontiers in Congenital Disorders of Glycosylation (FCDGC) Natural History cohort at year 5 of the study. Methods: We enrolled individuals with a known or suspected CDG into the FCDGC Natural History Study, a multicenter

Drawing on data from the United Kingdom, Sweden, Germany, and Switzerland, this article shows that during the process of interpreting the refugee definition and applying it to the context of the Eritrean Military/National Service Programme (MNSP), the definition is subject to various interpretations and applications. As a result, the treatment of similarly situated Eritrean asylum applications dif

Social entrepreneurship research highlights the collaborative nature of social entrepreneurial efforts. Further, acknowledging the embeddedness of social ventures in the wider socio-economic and cultural context, the literature stresses the need to move our analysis from the micro-level of intra-organisational practices to the meso-level of inter-organisational dynamics. To answer to these calls,

The concept of self-stigmatization is guided by a representational account of selfhood that fails to accommodate for resilience against, and recovery from, stigma. Mainstream research on self-stigma has portrayed it only as a reified self, that is, as collectively shared stereotypes representing individuals’ identity. Self-stigma viewed phenomenologically, however, elucidates what facilitates a st

The experimental methodology achieved in the present study signified that the adsorption and precipitation were main mechanisms occurred together in the removal of nickel from aqueous solution by sorption using cement kiln dust (CKD) byproduct as sorbent. Finding the contribution of each mechanism in the removal process and derivation an analytical model for finding the portion of precipitation we

Cardiac thromboembolism attributed to atrial fibrillation (AF) is responsible for up to one-third of ischemic strokes. Stroke may be the first manifestation of previously undetected AF. Given the efficacy of oral anticoagulants in preventing AF-related ischemic strokes, strategies of searching for AF after a stroke using ECG monitoring followed by oral anticoagulation (OAC) treatment have been pro

Paper copies of digital radiographs printed with the continuous ink-jet technique have proved to be of a high enough quality for demonstration purposes. We present a study on the image quality of ink-jet printed paper copies of digital chest radiographs, based on receiver operating characteristic (ROC) analysis. Eighty-three digital radiographs of a chest phatom with simulated tumors in the medias

Insects have evolved diverse and remarkable strategies for navigating in various ecologies all over the world. Regardless of species, insects share the presence of a group of morphologically conserved neuropils known collectively as the central complex (CX). The CX is a navigational center, involved in sensory integration and coordinated motor activity. Despite the fact that our understanding of n

Aim: The aim of the study was to explore the assessment fidelity of Språkfyran, a language screening instrument for four-year-old children. Språkfyran is a mandatory part of the healthcare program within the Swedish Child Health Service (CHS) and is offered to all four-year-olds in the region Scania in Sweden. Methods: The study was based on structured observations of twenty-four specialist CHS nu

The concept of critical performativity–efforts to make critical research more relevant for groups outside academia and develop and communicate action-relevant critical insights with some potential effect–has received considerable interest. Much of this has focused on debates about the core concept and principles. This paper argues for the need to “do”–more than talk about–critical performativity a

In this chapter, an individual life story of a shipyard blacksmith is the point of departure for discussing elderly men’s labour market experiences. This story, which can be summarized as occupational continuity in a turbulent period, is in line with an optimistic view of the situation of elderly men in an era of profound changes in the technology and organization of work, is contrasted against th

Technical innovations in the area of manufacturing logistics are being introduced partially and thus not exploiting their full potential. In order to optimise the efficiency of turning manufacturing processes, the process has been analysed and fundamentally re-engineered. All data from production (operations, quantities, date, time duration of operations, etc.) are now located in ERPsystem. It pro

Previous studies indicate that the sound environments normally present at hospitals in general and intensive care units in particular, may pose a risk for prolonged patient recovery and for the personnel, disruption of concentration, increased tiredness and possibly more errors. As part of a larger study of the effects of the sound environment in intensive care units (ICU), personnel response was

Swedish nursing homes' use of Instagram has increased vastly in the past few years. Instagram is understood as a means to manage the image they wish to mediate to the public. This article examines what is displayed in the nursing homes' Instagram accounts, and what kind of reality is thereby constructed. The data consist of 338 Instagram images from four nursing homes' Instagram accounts. It is fo
