We investigate patterns of collective phase synchronization in brain activity in awake, resting humans with eyes closed. The alpha range of human electroencephalographic activity is characterized by ever-changing patterns, with strong fluctuations in both time and overall level of phase synchronization. The correlations of these patterns are reflected in power-law scaling of these properties. We p

High-density, 256-channel, event-related potentials (ERP) were recorded in 12 subjects, who had to find a triangle of which only the corners were marked in an array of distracters. The orientation of the corner markers to each other and their proximity varied across trials. An early, pre-attentional, nonspatial effect of marker orientation was found at 64 and 100 ms after stimulus presentation in

Introduction It has been known for centuries that environment in healthcare has an impact, but despite this, environment has been overshadowed by technological and medical progress, especially in intensive care. Evidence-based design is a concept concerning integrating knowledge from various research disciplines and its application to healing environments. Objective The aim was to explore the expe

The fabrication of complex nanoscale electronics with reduced dimensions poses challenges on novel techniques to accurately determine fundamental electronic parameters. In this article, we present a universal contactless method based on Raman scattering for measuring the mobility and hole concentration independently in GaAs:Zn and Mn ion-implanted GaAs:Zn nanowires, potentially of great interest f

Avhandlingen undersöker användares upplevelser och beteende kopplat till belysning, ljusarmaturer och fönsteröppningar i svenska hem såväl dag som natt. En kombinerad undersökningsstrategi används där både kvantitativt och kvalitativt material samlats in i fält och i en fullskalemodell av en lägenhet. I avhandlingen identifieras flera motiv bakom boendes ljusrelaterade beteende och val samt faktorThe thesis examines user experience and behaviour relating to lighting, luminaires and window openings during day and night, in Swedish homes. Applying a mixed methods strategy of inquiry, both quantitative and qualitative data were collected in the field and in a full-scale model of an apartment. The thesis has identified multiple motivations behind residents’ lighting behaviour and choices, enab

Aim and objectives: To explore the experiences and views of nurses who provide nonpharmacological therapies for chronic pain management in palliative care. Background: Nursing expertise in palliative care is essential in providing pain relief to patients with chronic diseases. Examinations of the use of nonpharmacological therapies for chronic pain management in palliative care have revealed what

With the aim of clarifying critical care nursing, six critical care nurses, working in a Swedish intensive care unit (ICU) were each asked to narrate a care situation with which they had been satisfied or dissatisfied. The stories were tape-recorded and analysed using a phenomenological-hermeneutic approach inspired by the philosophy of Ricoeur. The themes uncovered in the analysis describe the nu

In the present paper, the heat transfer of gravity-driven dense particle flow around a hexagonal tube is numerically studied. The velocity vector, time-averaged particle contacting number, particle contacting time and heat transfer coefficient of particle flow are carfully analyzed. Furthermore, the heat transfer performances of particle flow around a hexagonal tube, circular tube and elliptical t

This study investigates the potential for Electrical Resistivity Tomography (ERT) to detect buried glass ‘hotspots’ in a glass waste dump based on results from an open glass dump investigated initially. This detection potential is vital for excavation and later use of buried materials as secondary resources. After ERT, test pits (TPs) were excavated around suspected glass hotspots and physico-chem

Increased divorce rates over the past century are linked to changing macroeconomic conditions, increased female independence and welfare state expenditure, but few studies have assessed these long-term relationships at the macro level. Research has focused on Anglo-Saxon contexts and not considered developments in vanguard countries like Sweden that determined their role as sociodemographic precur

Regeneration of complex multi-tissue structures, such as limbs, requires the coordinated effort of multiple cell types. In axolotl limb regeneration, the wound epidermis and blastema have been extensively studied via histology, grafting, and bulk-tissue RNA-sequencing. However, defining the contributions of these tissues is hindered due to limited information regarding the molecular identity of th

This article explores the paradox of corporations using social and environmental justice concerns to market products that are themselves made in conditions of environmental and social injustice, most often in the Global South. The effects of the fashion industry on people is two-pronged: 1) the unsafe and exploitative conditions under which many garment workers operate, and 2) the severe and harmf

Intense local heating of Si O2 is shown to occur during chemical vapor deposition growth of single-walled carbon nanotubes in the presence of an electric field. This gives rise to the Marangoni effect where strong convection currents are induced in the molten Si O2 layer. Nanoscale trenches and bumps are formed in the insulating layer directly below the growing nanotube.

The streaming instability is a leading candidate mechanism to explain the formation of planetesimals. However, the role of this instability in the driving of turbulence in protoplanetary disks, given its fundamental nature as a linear hydrodynamical instability, has so far not been investigated in detail. We study the turbulence that is induced by the streaming instability as well as its interacti

The article traces the development of narrative complexity in the book and television versions of Lemony Snicket's A Series of Unfortunate Events. The series has been criticized for its repetitive structure; however, drawing on seriality theory by Umberto Eco, Jason Mittell and Frank Kelleter, I demonstrate how it does move beyond repetition and towards a more complex narrative structure. I point

Glioblastoma multiforme is characterized in part by severe hypoxia associated with tumor necrosis. The cellular response to hypoxia can influence several properties of tumor cells associated with aggressive tumor growth, including metabolic adaptations and tumor cell migration and invasion. Here, we found that Delta Like Non-Canonical Notch Ligand 1 (DLK1) expression was elevated as compared with

Nigeria has the highest number of AIDS-related deaths in the world. In this study, we characterised the HIV-1 molecular epidemiology by analysing 1442 HIV-1 pol sequences collected 1999-2014 from four geopolitical zones in Nigeria using state-of-the-art maximum-likelihood and Bayesian phylogenetic analyses. The main circulating forms were the circulating recombinant form (CRF) 02_AG (44% of the an

Objective: Vaccinating healthcare workers (HCWs) against influenza is one of the most important methods of decreasing influenza transmission among at-risk patients in healthcare facilities. However, despite recommendations, the rate of uptake of influenza vaccine among HCWs remains low. The objective of this metaanalysis was to determine the most important predictors of seasonal influenza vaccine

In this licentiate thesis, I explore how two theoretical frameworks—social semiotics and the variation theory of learning—used in physics education research, can be fruitfully combined to obtain additional analytical tools for analysing student learning in introductory level university physics. Each theoretical framework has on their own, or together with other frameworks, been successfully applie
