The present study examines behavioral and metacognitive effects of visualizing acquired knowledge in instructional software. This was done by letting 117 Swedish primary school students use two varieties of an educational game – one with and one without a tool where tokens with knowledge related content were received as proofs of achievement. Although no significant positive impact of the tool was
The spatial patterns of precipitation regarding physiography and atmospheric circulations in the Lake Urmia Basin have been investigated. Daily rainfall time series for the 50 most reliable precipitation stations for the period 1980-2010 were analyzed to detect the regional precipitation pattern. To identify rainfall homogeneous regions, principal component analysis was applied to the precipitatio
This article casts light on the development of new regional industrial paths. We explore factors explaining why regional industries with similar early path development trajectories may exhibit diverging outcomes in the longer run and pay particular attention to the role of ‘outsiders’ in the initiation and further development of regional industrial paths. Drawing on a comparative case study of IT
Visually guided behaviour is constrained by the capacity of the visual system to resolve detail. This, in turn, is limited by the spatial resolution and contrast sensitivity of the underlying visual system. Because these properties are interdependent and vary nonuniformly, it is only possible to fully understand the limits of a specific visually guided behaviour when they are investigated in combi
Pancreatic cancer (PC) has an exceptionally low survival rate and primary prevention strategies are limited. Folate plays an important role in one-carbon metabolism and has been associated with the risk of several cancers, but not consistently with PC risk. We aimed to investigate the association between dietary folate intake and PC risk, using the standardised folate database across 10 European c
Våra jordar är basen för en hållbar matproduktion. Vi har tagit jorden och jordarna för självklara men jordens hälsa är en garanti för framtiden. Jorden vi trampar på är av största vikt för allt levande på land. Med tanke på den alarmerande hastighet med vilken världens jordar håller på att förstöras är det viktigt att fästa uppmärksamheten på jord som en värdefull resurs som måste bevaras och utn
A third of dementia cases could be attributable to modifiable risk-factors. Midlife high-density lipoprotein cholesterol (HDL-C) is a measure which could help identify individuals at reduced risk of developing age-related cognitive decline. The Japan Public Health Centre-based prospective (JPHC) Study is a large population-based cohort which started in 1990. This study included 1299 participants f
One aspect of tombs and burials in the BA Aegean in general that has not received much notice is that of color (hue and shine). Were certain hues more predominant than others? Was this significant? Was the presence (or absence) of shine of importance? Following a discussion of ‘what is color?’, the study and results of the colors of the finds from Late Bronze Age tombs at three sites in the Greek
OBJECTIVES: We wanted to examine reasons for the different incidence trends for cervical squamous cell carcinoma (SCC, declining) and adenocarcinoma (increasing).METHODS: The Swedish Family-Cancer Database on 9.6 million individuals was used to derive incidence trends between 1958 and 1996. Cervical cancers were compared to vaginal and vulvar cancers.RESULTS: A total of 15405 invasive cervical SCC
After insulin administration in vivo, changes in pancreatic lipase, colipase and amylase contents and outputs were assayed and quantitatively compared. The incorporation of [35S]cysteine into individual enzymes was measured. The mRNA coding for lipase and amylase were determined by dot-blot hybridization. It was found that insulin dose-dependently decreased lipase and colipase contents, but only s
The shape and diversity of dwarf galaxy rotation curves is at apparent odds with dark matter halos in a Λ Cold Dark Matter (ΛCDM) cosmology. We use mock data from isolated dwarf galaxy simulations to show that this owes to three main effects. Firstly, stellar feedback heats dark matter, leading to a `coreNFW' dark matter density profile with a slowly rising rotation curve. Secondly, if close to a
For classical tomography, it is essential that the sample does not change during the acquisition of one tomographic rotation. We derived and successfully implemented a tomographic reconstruction method, which relaxes this requirement of quasistatic samples. In the present paper, dynamic tomographic data sets are decomposed in the temporal domain by projecting to a lower dimensional subspace of bas
While largely studied in the macroscopic scale, the dynamics leading to the nucleation and fission of atmospheric aerosols are very poorly understood at the nano or molecular scale. A model system consisting on ionized hydrogen-bonded ammonia and water molecules have been studied experimentally using mass- and 3D momentum spectroscopy and theoretically using ab initio molecular dynamics simulation
The effect of electroporation parameters on the reversible permeabilization of cells in Thai basil leaves and, specifically, cells on the leaf surface was investigated, as electroporation of stomatal guard cells decreases drying times. Various combinations of PEF and MEF parameters were applied. The effect of these parameters on the electroporation of the leaf surface was assessed with microscopic
Introduction: The prevalence of arthropathy in moderate haemophilia A (MHA) and B (MHB) is not well known. Aim: We evaluated joint health in Nordic patients in relation to their treatment modality. Methods: A cross-sectional, multicentre study covering MHA and MHB in Sweden, Finland and Norway. Arthropathy was evaluated by ultrasound (HEAD-US) and Haemophilia Joint Health Score (HJHS). Results: We
Citrus intake has been suggested to increase the risk of skin cancer. Although this relation is highly plausible biologically, epidemiologic evidence is lacking. We aimed to examine the potential association between citrus intake and skin cancer risk. EPIC is an ongoing multi-center prospective cohort initiated in 1992 and involving ~ 520,000 participants who have been followed-up in 23 centers fr
