Synthesis of Na2Ti3O7 nanorods by a V-assisted route and investigation of their battery performance

We report the V-assisted synthesis of Na2Ti3O7 nanorods via a conventional solid state reaction technique. Energy dispersive X-ray spectroscopy (EDS) mapping showed that V-ions are not incorporated into the main structure of the nanorods but rather V behaves as a flux agent during the growth of the nanorods. The cyclic voltammetry (CV) analysis of the samples shows changes in the redox peaks as a

Agricultural productivity in relation to climate and cropland management in West Africa

The climate of West Africa is expected to become more arid due to increased temperature and uncertain rainfall regimes, while its population is expected to grow faster than the rest of the world. As such, increased demand for food will likely coincide with declines in agricultural production in a region where severe undernutrition already occurs. Here, we attempt to discriminate between the impact

Reducing deforestation in Colombia while building peace and pursuing business as usual extractivism?

In this article, I examine the contradictions and tensions in Colombia's simultaneous embrace of REDD+ and a peace-building process premised on continued extractivism. Colombia is emerging from an internal conflict that lasted more than 50 years. In this process rural land-use is being transformed, generating new conflicts over land use and control with detrimental effects on Colombia's forests. B

Maintaining registration and tax benefits: Consequences for professionalisation of voluntary membership organisations in Norway and the UK

This article investigates how regulation related to maintaining state registration and tax beneficial status affects professionalisation, covering paid staff and volunteers with specialist skills, of political parties, advocacy groups and service providing organisations. The article fills a gap in the literature which until now has been mainly concerned with the influence of state funding on profe

Institutional and symbolic aspects of illiberal politics: the case of North Macedonia (2006–2017)

The paper discusses the underlying characteristics of Macedonian illiberal politics during the 11-year rule of the centre-right party VMRO-DPMNE (2006–2017) focusing on two aspects: institutional and symbolic. We argue that the unfair political competition was enabled by the weakness of pre-existing institutions and the population’s clientelist preferences, which were systematically exploited and

The matched reassigned cross-spectrogram for phase estimation

In this paper, the matched reassigned spectrogram is expanded into a novel matched phase reassignment (MPR) method based on the reassigned cross-spectrogram. It is shown that for two phase synchronized oscillating transient signals, the method gives perfect time-frequency (TF) localization. The MPR is thereby a TF local measure of phase synchronization and can also be used to measure phase differe

Labour and the ‘law of one price’ : regional wage convergence of farm workers in Sweden, 1757–1980

Economic theory predicts that differences in wages for workers with similar skills will decline as labour mobility increase. This prediction is reminiscent of the ‘law of one price’, the notion that markets, if unfettered, eliminates price differentials of similar commodities across space. But can we really apply the economic logic of the commodity market to the labour market, governed as it is by

Primary fatty amides in plasma associated with brain amyloid burden, hippocampal volume, and memory in the European Medical Information Framework for Alzheimer's Disease biomarker discovery cohort

Introduction: A critical and as-yet unmet need in Alzheimer's disease (AD) is the discovery of peripheral small molecule biomarkers. Given that brain pathology precedes clinical symptom onset, we set out to test whether metabolites in blood associated with pathology as indexed by cerebrospinal fluid (CSF) AD biomarkers. Methods: This study analyzed 593 plasma samples selected from the European Med

When technology enters the home – a systematic and integrative review examining the influence of technology on the meaning of home

Aim: To analyse and synthesise the research that has investigated the experience of home in relation to home mechanical ventilation (HMV). Method: Systematic integrative review. Four electronic databases (CINAHL, PubMed, Scopus and ISI Web of Knowledge) were searched between January 2010 and April 2017 as well as reference lists of included studies. Quantitative and qualitative studies meeting the

A quantitative model of cellular decision making in direct neuronal reprogramming

The direct reprogramming of adult skin fibroblasts to neurons is thought to be controlled by a small set of interacting gene regulators. Here, we investigate how the interaction dynamics between these regulating factors coordinate cellular decision making in direct neuronal reprogramming. We put forward a quantitative model of the governing gene regulatory system, supported by measurements of mRNA

Huntingtons sjukdom – kliniska prövningar inger nu optimism - Vanligaste formen av ärftlig neurodegenerativ sjukdom i västvärlden ger svåra symtom och förtidig död

Huntington's disease is an autosomal dominant neurodegenerative disease that leads to premature death. The disease is caused by a pathological CAG triplet expansion in the huntingtin gene. The disease is most common in Western populations, with onset in middle age and causing progressive motor, cognitive, and psychiatric symptoms. Currently, only symptomatic treatment is provided, but new molecula

Bat Fatalities at Wind-Farms in the Lowland Mediterranean of Southern Spain

Wind energy is an important source of bat mortality worldwide. Extensive mortality data were gathered by a provincial surveillance program carried out at wind farms in lowland Mediterranean areas of the province of Cadiz, Andalusia (South Spain) between 2005 and 2016. As many as 2,371 bat fatalities were found. We determined the patterns of fatality in this sample and tested the quality of the sur

Renewable Energy Adoption: Is current growth enough to meet future climate targets?

Every year, the world adds more renewable energy production capacity than the year before. But, looking historically, is this growth enough to achieve our climate targets? According to a recent publication in ‘Nature Energy’, the short answer is “no” – to meet the climate goals requires decades of growth in renewables at rates higher than those observed historically in most countries. In this epis

Mercury–Selenium Accumulation Patterns in Muscle Tissue of Two Freshwater Fish Species, Eurasian Perch (Perca fluviatilis) and Vendace (Coregonus albula)

Mercury (Hg) in the form of highly toxic methyl mercury (MeHg) accumulates in aquatic food webs to an extent where it may threaten fish health in many freshwaters. Selenium (Se) mitigates the toxicity of accumulated Hg by forming strong bonds with it, a drawback being diversion of Se from biosynthetic pathways of essential selenoenzymes. We measured Se and Hg in muscle tissue of Eurasian perch (Pe

A model of wild bee populations accounting for spatial heterogeneity and climate-induced temporal variability of food resources at the landscape level

The viability of wild bee populations and the pollination services that they provide are driven by the availability of food resources during their activity period and within the surroundings of their nesting sites. Changes in climate and land use influence the availability of these resources and are major threats to declining bee populations. Because wild bees may be vulnerable to interactions bet

Early and Late Migrating Avian Individuals Differ in Constitutive Immune Function and Blood Parasite Infections – But Patterns Depend on the Migratory Strategy

Billions of birds migrate every year. To conduct a successful migration, birds undergo a multitude of physiological adaptions. One such adaptation includes adjustments of immune function, however, little is known about intraspecies (between-individual) and interspecies (between-species) variation in immune modulations during migration. Here, we explore if early and late migrating individuals diffe

Accuracy of a Bayesian technique to estimate position and activity of orphan gamma-ray sources by mobile gamma spectrometry : Influence of imprecisions in positioning systems and computational approximations

The purpose of this study was to investigate the effects of experimental data on performance of a developed Bayesian algorithm tailored for orphan source search, estimating which parameters affect the accuracy of the algorithm. The algorithm can estimate the position and activity of a gamma-ray point source from experimental mobile gamma spectrometry data. Bayesian estimates were made for source p

Why having 10,000 parameters in your camera model is better than twelve

Camera calibration is an essential first step in setting up 3D Computer Vision systems. Commonly used parametric camera models are limited to a few degrees of freedom and thus often do not optimally fit to complex real lens distortion. In contrast, generic camera models allow for very accurate calibration due to their flexibility. Despite this, they have seen little use in practice. In this paper,
