Proposing and investigating PCAMARS as a novel model for NO2 interpolation

Effective measurement of exposure to air pollution, not least NO2, for epidemiological studies along with the need to better management and control of air pollution in urban areas ask for precise interpolation and determination of the concentration of pollutants in nonmonitored spots. A variety of approaches have been developed and used. This paper aims to propose, develop, and test a spatial pred

Sand drift events and surface winds in south-central Sweden : From the deglaciation to the present

During the transition from the last glacial into the Holocene interglacial, the atmospheric circulation in the North Atlantic area changed from a glacial mode, influenced by the presence of large ice sheets, into a system more similar to that of the present day. This change had implications for wind, temperature and precipitation patterns that can be traced in geological archives. Here, we focus o

Need a bag? A review of public policies on plastic carrier bags – Where, how and to what effect?

The plastic carrier bag epitomises many of the features that have transformed plastics into a material that defines our contemporary modern culture. The versatility, durability, strength and low cost have made it into an indispensable companion for consumers. In parallel with plastic becoming an increasingly contested material, the plastic carrier bag has emerged as a controversial object in many

An assessment of achievements of the WEEE Directive in promoting movement up the waste hierarchy : experiences in the UK

Rapidly developing technology and an increasing number of products containing electrical or electronic functions, has led to discarded electrical and electronic equipment (EEE) being one of the fastest growing waste streams. The European Union (EU) has enacted several iterations of the Waste Electrical and Electronic Equipment (WEEE) Directive to address this complex waste stream. However, recycli

Pressure measurement in combusting and non-combusting gases using laser-induced grating spectroscopy

The measurement of pressure using laser-induced thermal grating spectroscopy, LITGS, with improved accuracy and precision is reported. Pressure values are derived from the record of the time-profile of LITGS signals by fitting of modelled signals to experimental data. The procedure is described for accurate modelling of the LIGS signals involving a sequence of calculation steps with appropriate w

APP depletion alters selective pre- and post-synaptic proteins

The normal role of Alzheimer's disease (AD)-linked amyloid precursor protein (APP) in the brain remains incompletely understood. Previous studies have reported that lack of APP has detrimental effects on spines and electrophysiological parameters. APP has been described to be important in synaptic pruning during development. The effect of APP knockout on mature synapses is complicated by this role

The populist allure of social media activism: Individualized charismatic authority

This article argues that the type of individualized social media activism that has been conceptualized as ‘connective action’ has affinities to populism, and may have detrimental consequences for democratic procedures and the bureaucratic structures that enable them. We trace the normative allure of individualized digital engagement to the libertarian roots of techno-utopianism and argue that this

Come together-the development of Swedish energy communities

Community energy (CE) and grassroots innovations have been widely studied in recent years, especially in the UK, Germany, and the Netherlands, but very little focus has been placed on Sweden. This paper describes and analyses the development and present state of several types of community energy initiatives in Sweden. The methodology uses interviews, document studies, analysis of previous studies,

A walk through tau therapeutic strategies

Tau neuronal and glial pathologies drive the clinical presentation of Alzheimer's disease and related human tauopathies. There is a growing body of evidence indicating that pathological tau species can travel from cell to cell and spread the pathology through the brain. Throughout the last decade, physiological and pathological tau have become attractive targets for AD therapies. Several therapeut

Att låna (fruar och salt)

Ofta används uttrycket 'får jag låna...' utan att riktigt att ha en tanke på att lämna tillbaks saltkornen, toaletten eller tändstickan. Bidraget diskuterar vad som upplevs som oproblematiskt att låna, och vilka förfrågningar som kan orsaka starka känslor.

Inga minskade utsläpp utan marknadsekonomi

Planekonomi kommer aldrig att kunna lösa klimatproblemen. Statens roll i att bidra till en klimatomställning handlar enbart om att skapa incitament för marknaden att lösa problemen. ”Lösningar” som beskattning av utsläpp är inte relevanta förrän marknaden kan erbjuda verkliga alternativ till fossila bränslen.

Equalization of four cardiovascular risk algorithms after systematic recalibration: individual-participant meta-analysis of 86 prospective studies

AIMS: There is debate about the optimum algorithm for cardiovascular disease (CVD) risk estimation. We conducted head-to-head comparisons of four algorithms recommended by primary prevention guidelines, before and after 'recalibration', a method that adapts risk algorithms to take account of differences in the risk characteristics of the populations being studied. METHODS AND RESULTS: Using indivi
