Lake ice is a sensitive indicator of climate change. Based on the disparities between the brightness temperatures of lake ice and water, passive microwave data can be used to monitor the ice variations of a lake. With focus on the analysis of long time series variability of lake ice, this study extracts four characteristic dates related to lake ice (the annual freeze start, freeze completion, abla

The information of water surface temperature (WST) is essential for many applications such as the estimation of evaporation from lakes and reservoirs. Generally, there is rarely continuous long-term in-situ measurement of water surface temperature for most lakes especially in developing countries. The freely available satellite data is an alternative or even the only data source for obtaining WST

The information of water level variations in lakes and reservoirs is essential for many applications such as water resources management. The conventional in-situ measurements of water levels based on gauge station are often rarely available or difficult to be shared to the public especially for lakes in the developing countries and transboundary basins. Satellite altimetry provides an alternative

Inslag av ämnesdidaktik i de högskolepedagogiska kurser som erbjuds idag är i stort sett obefintligt. För att råda bot på den bristen när det gäller matematik har en fem veckors kurs i matematikdidaktik för högskolan utvecklats och givits vid matematikcentrum under år 2005. Kursen fick många deltagare bland doktorander och yngre lärare och blev uppskattad. Vi beskriver motiven till att kursen kom

The purpose of this essay is to demonstrate how a new history of the postwar humanities could be written. Drawing on approaches from the history of knowledge and other adjacent fields, it outlines a study of the conditions of the circulation of knowledge in the public sphere during the 1960s and 1970s. By introducing “arena of knowledge” as an analytical concept, the essay highlights certain media

Psychological models of pediatric obsessive-compulsive disorder (OCD) place a heavy emphasis on harm avoidance as a maintaining factor and target for treatment. Incompleteness and disgust may also play a role in pediatric OCD but remain under studied. Youth with OCD (n=100), anxiety disorders (n=96), and no psychiatric disorder (n=25) completed self-report measures of trait-level incompleteness, h

The global public health problem of intimate partner violence against women (IPVAW) is typically tied to gender inequality. Contrary to what would be expected, however, a 2012 survey conducted by the European Union Agency for Fundamental Rights (FRA) showed lifetime prevalence rates of IPVAW in the Nordic countries which were among the highest of the 28 EU member states, despite these countries be

Parkinson’s Disease (PD) is the most prevalent neurodegenerative movement disorder. Despite investigative efforts into the pathogenesis of the disease, the aetiology and mechanism of PD remains unknown, with multiple factors and cellular pathways known to play a part. But the genetic component of the disease, as well as enhanced vulnerability of the midbrain dopaminergic neurons of the Substantia

Hybrid organo-metal halide perovskites are an exciting new class of solar absorber materials and have exhibited a rapid increase in solar cell efficiencies throughout the past two years to over 17% in both meso-structured and thin-film device architectures. We observe slow transient effects causing hysteresis in the current-voltage characterization of these devices that can lead to an over- or und

We combine droplet epitaxy with low-energy electron microscopy imaging techniques to map the surface phase diagram of GaAs(001). The phase patterns produced in droplet epitaxy are interpreted using a simple model which links the spatial coordinates of phase boundaries to the free energy. It is thereby possible to gain important information on surface phase stability, based on the observed sequenti

Background: The dGEMRIC (delayed Gadolinium-Enhanced MRI of Cartilage) technique has been used in numerous studies for quantitative in vivo evaluation of the relative glycosaminoglycan (GAG) content in cartilage. The purpose of this study was to determine the influence of pre-contrast T1 and cartilage thickness when assessing knee joint cartilage quality with dGEMRIC. Methods: Cartilage thickness

Previous studies report that dental caries is partially heritable, but there is uncertainty in the magnitude of genetic effects and little understanding of how genetic factors might influence caries progression or caries subtypes. This study aimed to estimate the relative importance of genetic and environmental factors in the etiology of different caries outcomes using a twin-based design. Analysi

Using a dataset with over 24 million year-employment observations and the universe of more than 230,000 entries into entrepreneurship in one economy we analyze the gross (including the founders), net (excluding the founders), and new (jobs to the former unemployed or those outside the labor force) job creation by entrepreneurs two and six years after start-up. These novel measures of job creation

BACKGROUND: We investigated the potential associations between cerebro-spinal fluid (CSF) levels of phosphorylated tau (P-tau) and total tau (T-tau) with short-term response to cholinesterase inhibitor (ChEI) treatment, longitudinal outcome and progression rates in Alzheimer's disease (AD). METHODS: This prospective, observational study included 129 participants clinically diagnosed with mild-to-m
