I denna bok utgår författarna både från experimentalfysikens varför och experimentalfysikens hur. De ger bakgrunder och visioner tillsammans med handfasta kunskaper inom den experimentella fysiken. Boken är främst avsedd för teknologer, naturvetare och lärare. Men framställningen är medvetet utformad för att också kunna nå utanför denna krets, och bokens första halva kräver inga speciella matemati
Purpose – The purpose of this article is to understand what role researchers assign to online representations on the new digital communication sites that have emerged, such as Academia, ResearchGate or Mendeley. How are researchers’ online presentations created, managed, accessed and, more generally, viewed by academic researchers themselves? And how are expectations of the academic reward system
Purpose: This study explores how information on air pollution is shaped online on an everyday basis, with a particular emphasis on digital devices and digital representations as constitutive of environmental information practices. Furthermore, this research highlights an understudied aspect of air pollution – the digital flow of multimodal representations that citizens encounter and produce in the
Under andra veckan av augusti genomfördes 1000 telefonintervjuer på temat allmänhetens attityd till användandet av övervakningskameror på gator och torg. 90% av allmänheten svarade positivt när de ställdes frågan ”Vad tycker du om övervakningskameror på allmän plats?” uppdelat på 49% som ställde sig mycket positiva och 41% som ställde sig ganska positiva. Vidare ansåg 72% av de tillfrågade att det
The aim of this research was to develop new biobased non-ionic polymeric additives with significant bacterial inhibition and low leaching potential, so that they can be used to produce biopolymer materials for various applications such as biomedical devices, surgical textile, or food packaging. Two new non-ionic hyperbranched polymers (HBPs) were prepared by a facile solvent-free polymerization of
BackgroundThe demography of the world is changing as the population is ageing. Because of this change to a higher proportion of older people, the WHO has called for improved palliative care for older persons. A large number of all deaths in the industrialised world occur while older people are living in nursing homes and therefore a key question becomes how the principles of palliative care can be
Plastics are versatile materials with environmental, technical, economical and societal benefits, however plastics also contribute negatively to the environment and climate. Put in numbers around 4% of the fossil oil and gas is used as feedstock for plastics while another 4% is used for providing energy for the manufacturing of plastics. Many initiatives on reducing the negative effects of plastic
PurposeThe aim of the study is to create knowledge on how Google and Google search are discursively constructed as a political subject suitable or not suitable for governing in the debate regarding the Right to be Forgotten ruling (RTBF). Design/Methodology/Approach28 texts are analysed using a Foucauldian discourse analysis focusing on political problematisations in the media and in blogs. Find
The ability of state-of-the-art regional climate models to simulate cyclone activity in the Arctic is assessed based on an ensemble of 13 simulations from 11 models from the Arctic-CORDEX initiative. Some models employ large-scale spectral nudging techniques. Cyclone characteristics simulated by the ensemble are compared with the results forced by four reanalyses (ERA-Interim, National Centers for
Radar signature measurements of targets with or without camouflage in different backgrounds using airborne SAR are complex and expensive. Measurements at many orientations as well as illumination angles have to be performed for each target for completeness. A more efficient solution is to use ground based ISAR measurements of the desired targets and then blend these images into measured SAR scenes
Background: To determine the association between time from injury to ACL reconstruction (TimeInjury-ACLR) and biochemical markers of cartilage metabolism and inflammation six months following ACL reconstruction (ACLR). Methods: Individuals with a unilateral ACL injury were enrolled at initial presentation in the orthopedic clinic; blood was collected six months following ACLR. Enzyme-linked immuno
Objective: Retrograde open mesenteric stenting (ROMS) through laparotomy was introduced as an alternative to surgical bypass in patients with acute mesenteric ischemia (AMI). The purpose of this study was to evaluate the indications and outcomes of ROMS for treatment of AMI and chronic mesenteric ischemia. Methods: We reviewed the clinical data and outcomes of all consecutive patients treated by R
Nonlinear light-matter interactions, such as filamentation or high-order harmonic generation, are at the heart of nonlinear optics. Scaling of such effects is crucial to benefit optimally from novel laser developments. We introduce and discuss a general scaling model for nonlinear light-matter interactions in gases.
Background: Lung T1 is a potential translational biomarker of lung disease. The precision and repeatability of variable flip angle (VFA) T1 mapping using modern 3D ultrashort echo time (UTE) imaging of the whole lung needs to be established before it can be used to assess response to disease and therapy. Purpose: To evaluate the feasibility of regional lung T1 quantification with VFA 3D-UTE and to
Background: Optimal follow-up (FU) strategy to detect potentially curable (PC) recurrences after treatment of localised clear cell renal cell carcinoma (ccRCC) is unclear. This study retrospectively analysed a large international database to determine recurrence patterns and overall survival (OS), as part of a wider project to issue recommendations on FU protocols. Objective: To analyse associatio
