Nanoplastics formed during the mechanical breakdown of daily-use polystyrene products

Large amounts of plastics are released into the environment every day. These released plastics have a clearly documented negative effect on wildlife. Much research attention has been given to large plastic pieces and microplastics. However, if the breakdown of plastics is a continous process, eventually nanoplastics will be produced. Nanoplastics will affect wildlife differently from larger plasti

Workshop on Environmental Nanosafety: Biological Interactions of Plastic Nanoparticles

The one-hour workshop, containing both a demonstration and hands-on experiments on the topic of nanosafety, is based on current science on a topic of general interest. The workshop aims to provide a deeper knowledge and understanding of nanoparticles. The participants get an introduction to what nanoparticles are, why nanosized materials are interesting, how nanomaterials interact with biological The one-hour workshop, containing both a demonstration and hands-on experiments on the topic of nanosafety, is based on current science on a topic of general interest.

Tracking linguistic primitives : The phonosemantic realization of fundamental oppositional pairs

This paper investigates how cross-linguistic phoneme distributions of 56 fundamental oppositional concepts can reveal semantic relationships by looking into the linguistic forms of 75 genetically and areally distributed languages. Based on proposals of semantic primes (Goddard & Wierzbicka 2002), reduced Swadesh lists (Holman et al. 2008), presumed ultraconservative words (Pagel et al. 2013),

To learn to design is to learn to learn about possible futures: A learning perspective on design and its implications

Design requires thoughtful application of methods to broaden ones understanding of the task and to generate alternative solutions in the form of possible futures in relation to the task. These kind of activities implies learning. In an interaction design course for undergraduate engineering students, we noticed that students gave little effort to the usage of the design methodologies taught, and n

How European primary care practitioners think the timeliness of cancer diagnosis can be improved : a thematic analysis

BACKGROUND: National European cancer survival rates vary widely. Prolonged diagnostic intervals are thought to be a key factor in explaining these variations. Primary care practitioners (PCPs) frequently play a crucial role during initial cancer diagnosis; their knowledge could be used to improve the planning of more effective approaches to earlier cancer diagnosis. OBJECTIVES: This study sought t

Multiplicity conversion based on intramolecular triplet-to-singlet energy transfer

The ability to convert between molecular spin states is of utmost importance in materials chemistry. Förster-type energy transfer is based on dipole-dipole interactions and can therefore theoretically be used to convert between molecular spin states. Here, a molecular dyad that is capable of transferring energy from an excited triplet state to an excited singlet state is presented. The rate of con

Global microscopic calculations of odd-odd nuclei

The macroscopic-microscopic finite-range droplet model is combined with a particle-rotor coupling model in order to systematically describe low-energy spectra of odd-odd nuclei. The odd proton and neutron are allowed to interact through effective nuclear forces representing the residual neutron-proton interaction. In particular, ground-state spins and parities are calculated and compared to data,

Water and Thermal Properties Characterized in Phases of Wheat Flour Dough during Thawing and Baking Conditions

Phase separation of dough is based on the thermodynamic incompatibility of its components. The studies on phase-separated systems allow to model, understand, and develop foods. Model dough systems made with water and wheat flour were disassembled into their main structural phases, i.e. liquid, gel, gluten and starch phases, by ultracentrifugation, and further characterized with differential scanni

Clinical validation of the Swedish version of Dyspnoea-12 instrument in outpatients with cardiorespiratory disease

Introduction Breathlessness is the cardinal symptom in both cardiac and respiratory diseases, and includes multiple dimensions. The multidimensional instrument Dyspnoea-12 has been developed to assess both physical and affective components of breathlessness. This study aimed to perform a clinical validation of the Swedish version of Dyspnoea-12 in outpatients with cardiorespiratory disease. Method

Att göra trygghet i staden : Ett "samvärkande" projekt mellan kommun och civilsamhälle

I det första kapitlet presenteras tankar och koncept kring tillit och trygghet samt tidigare forskning om civilsamhället och relationen mellan den offentliga och den ideella sektorn. I andra kapitlet redogörs för projektets genomförande och olika steg. I rapportens tredje kapitel presenteras resultaten av arbetet. Rapporten avslutas med en sammanfattande reflektion kring ritualer och improvisation

The new London–Lund Corpus (LLC–2) : Design, compilation, access

This talk reports on the compilation of the new London–Lund Corpus (LLC–2) –a corpus of contemporary spoken British English, collected 2014–2019. The sizeand design of LLC–2 are the same as that of the world’s first corpus of spokenlanguage, namely the London–Lund Corpus (LLC–1), with spoken data mainlyfrom the 1960s. In addition to the fact that we have a corpus of contemporary speech, the existe

A Theoretical Twist on the Transparency of Open Notes : Qualitative Analysis of Health Care Professionals' Free-Text Answers

BACKGROUND: The New Public Management movement strove for transparency so that policy makers and citizens could gain insight into the work and performance of health care. As the use of the electronic health record (EHR) started to diffuse, a foundation was laid for enhanced transparency within and between health care organizations. Now we appear to be experiencing a new kind of transparency in the

Crystal structures of the Bacillus subtilis prophage lytic cassette proteins XepA and YomS.

As part of the Virus-X Consortium that aims to identify and characterize novel proteins and enzymes from bacteriophages and archaeal viruses, the genes of the putative lytic proteins XepA from Bacillus subtilis prophage PBSX and YomS from prophage SPβ were cloned and the proteins were subsequently produced and functionally characterized. In order to elucidate the role and the molecular mechanism o

Tool–chip thermal conductance coefficient and heat flux in machining : Theory, model and experiment

This study proposes a technique for determining a tool–chip thermal conductance coefficient and heat flux in machining. The technique is based on solving an inverse heat transfer problem (IHTP). Because the IHTP is ill-posed, a priori information is required for its effective solution. To derive this information, substantial qualitative and quantitative analysis of a mixed boundary value problem f
