In this contribution, we report about tomographic nanoscale imaging using a laser-produced plasma-based laboratory transmission X-ray microscope (LTXM) in the water window. The soft X-ray radiation of the LTXM is provided by a high average power laser-produced (1.3 kHz repetition rate, 0.5 ns pulse duration, 140 W average power) plasma source, a multilayer condenser mirror, an objective zone plate
Background: Behavioral testing provides an essential approach in further developing our understanding of brain structure and function. The aim of our study was to outline a more expanded approach to cognition- and anxiety-related behavior in the rabbit. Methods: Twenty-one 70-day old rabbits (13 female, 8 male) were exposed to open field test, dark-light box test and object recognition testing wit
Here, we report a sol-gel integrated affinity microarray for on-chip matrix-assisted laser desorption/ionization time-offlight mass spectrometry (MALDI-TOF-MS) that enables capture and identification of prostate-specific antigen (PSA) in samples. An anti-PSA antibody (H117) was mixed with a sol-gel, and the mixture was spotted onto a porous silicon (pSi) surface without additional surface modifica
In the era of the Internet of Things and social media; communities, governments, and corporations are increasingly eager to exploit new technological innovations in order to track and keep up to date with important new events. Examples of such events include the news, health related incidents, and other major occurrences such as earthquakes and landslides. This area of research commonly referred t
OBJECTIVE/BACKGROUND: To develop a procedure specific global rating scale for assessment of operator competence in endovascular aortic repair (EVAR).METHODS: A Delphi approach was used to achieve expert consensus. A panel of 32 international experts (median 300 EVAR procedures, range 200-3000) from vascular surgery (n = 21) and radiology (n = 11) was established. The first Delphi round was based o
DN DEBATT 22/3. Det svenska valet hotas av digitala påverkansoperationer där falska robot-konton och så kallade ”dark ads” kan dränka det politiska samtalet. Vi utmanar nu riksdagspartierna: Ge ett enkelt löfte till väljarna om att ni inte kommer att använda er av oetiska metoder på nätet, skriver Jonas Andersson Schwarz, Stefan Larsson och Anders Mildner.
Public relations was historically an isolated theoretical field and an, in practice, undeveloped organizational publicity function for many years. From the perspective of strategy research, theory as well as practice has traditionally been dominated by traditional, rational, linear and functionalistic approaches (Whittington, 2000). The foundation in functionalism has led researchers to focus on e
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
