Tabletop divergent-light halos

We study artificial halos generated by microscopic crystals suspended in an aqueous solution which is illuminated by a divergent light source. By measuring the diameters of the halos we can deduct the refracting angles of the crystals and compare them with known values.

Showcasing Seventeenth-Century Jesuit Astronomy In Asia : The Lead Up To The First Scientific Observations Of A Solar Eclipse Made In Siam

The first great ruler to encourage the adoption of Western culture and technology throughout Siam was King Narai, who also had a passion for astronomy. He showed this by encouraging French and other Jesuit missionaries, some with astronomical interests and training, to settle in Siam from the early 1660s. One of these was Father Antoine Thomas, and he was the first European known to have carried o

Cortical and white matter correlates of language-learning aptitudes

People learn new languages with varying degrees of success but what are the neuroanatomical correlates of the difference in language-learning aptitude? In this study, we set out to investigate how differences in cortical morphology and white matter microstructure correlate with aptitudes for vocabulary learning, phonetic memory, and grammatical inferencing as measured by the first-language neutral

A participatory approach to tracking system transformation in clusters and innovation ecosystems – evolving practice in Sweden’s Vinnväxt programme

For decades, cluster initiatives and funding programmes have been used as instruments of industrial and innovation policy – addressing system failures by strengthening linkages among actors, fostering innovation and developing more effective innovation systems. More recently, a growing segment of these initiatives are also focused on driving system-level transformation and contributing to broader For decades, cluster initiatives and funding programmes have been used as instruments of industrial and innovation policy – addressing system failures by strengthening linkages among actors, fostering innovation and developing more effective innovation systems.

Moving beyond traditional measures – lessons from evaluating collaborative initiatives at Lund University

Over the last decade, universities and other institutions of higher education (HEIs) worldwide have witnessed an evolution to their role relative to society – with increasing attention to external engagement and expectations on societal impact. This has fostered an upswing in activity as research and innovation funding bodies and universities alike explore new approaches to working with external eOver the last decade, universities and other institutions of higher education (HEIs) worldwide have witnessed an evolution to their role relative to society – with increasing attention to external engagement and expectations on societal impact.

Goffin's Cockatoos (Cacatua goffiniana) Can Solve a Novel Problem After Conflicting Past Experiences

Novel problems often partially overlap with familiar ones. Some features match the qualities of previous situations stored in long-term memory and therefore trigger their retrieval. Using relevant, while inhibiting irrelevant, memories to solve novel problems is a hallmark of behavioral flexibility in humans and has recently been demonstrated in great apes. This capacity has been proposed to promo

Characteristics of children diagnosed with type 1 diabetes before vs after 6 years of age in the TEDDY cohort study

AIMS/HYPOTHESIS: Prognostic factors and characteristics of children diagnosed with type 1 diabetes before 6 years of age were compared with those diagnosed at 6-13 years of age in the TEDDY study.METHODS: Genetically high-risk children (n = 8502) were followed from birth for a median of 9.9 years; 328 (3.9%) were diagnosed with type 1 diabetes. Cox proportional hazard model was used to assess the

Measuring the human element in cluster evaluation- evidencing collaborative dynamics

There is a general acceptance that social capital and trust are critical for effective cluster development. While this behavioural additionality forms the central rationale for cluster policies, it remains poorly captured in evaluation. This paper explores progress in evidencing the ‘human element’ in cluster performance.The paper describes a long-term process of collaboration between academics, c

Spatial Structures Formed during High-Temperature Vacuum Annealing of Diamond-Like Film Deposited on a Silicon Substrate

The process of an ultrahigh vacuum annealing of a diamond-like carbon film deposited on a silicon substrate has been studied in situ using a photoemission microscope mounted at the MAX-lab synchrotron's radiation source. After the annealing the film was examined ex situ using an atomic force microscope. It is revealed that the graphitization of the film occurs and round formations of several micro

Age and gender differences in risk factor burden, myocardial dysfunction and cardiovascular events in relation to glucose metabolism

Popular Abstract in Swedish Studier har visat att inte bara individer med diabetes utan ocksa de som har forstadier till diabetes, namligen forhojt fasteblodsocker och nedsatt glukostolerans, loper en okad risk for att drabbas av saval hjartkarlsjukdom som hjartsvikt. Daremot har man sett att den okade risken forenad med diabetes verkar minska med aldern. Studier pa aldre individer ar dock sparsamThe risk of cardiovascular disease (CVD) and heart failure (HF) among individuals with diabetes is at least two times greater than in non-diabetic subjects. However, the excess risk of CVD in diabetic subjects seems to decrease with age. As the majority of patients with diabetes, CVD and HF are elderly it is important to establish the extent to which the associations between these conditions diffe

Optimization of image quality and radiation dose in neuroradiological computed tomography

Background: The goal of clinical computed tomography (CT) is to produce images of diagnostic quality using the lowest possible radiation exposure. Degradation of image quality, with increased image noise and reduced spatial resolution, is a major limitation for radiation dose reduction in CT. This can be counteracted with new post-processing image filters and iterative reconstruction (IR) algorith

The life cycle costs of indoor climate systems in dwellings and offices taking into account system choice, airflow rate, health and productivity

The life cycle cost (LCC) of the heating, cooling and ventilation system was simulated for a typical cell office building, multi-family dwelling and detached house. Different ventilations systems were simulated resulting in different heating and cooling system designs. A health-related cost dependent on the airflow rate which was based on recent studies was added to the LCC for the dwellings as we

Lack of evidence for a role of islet autoimmunity in the aetiology of canine diabetes mellitus.

Diabetes mellitus is one of the most common endocrine disorders in dogs and is commonly proposed to be of autoimmune origin. Although the clinical presentation of human type 1 diabetes (T1D) and canine diabetes are similar, the aetiologies may differ. The aim of this study was to investigate if autoimmune aetiology resembling human T1D is as prevalent in dogs as previously reported.

Sexually Coercive Behavior in Male Youth: Population Survey of General and Specific Risk Factors.

Little is known about risk/protective factors for sexually coercive behavior in general population youth. We used a Swedish school-based population survey of sexual attitudes and experiences (response rate 77%) and investigated literature-based variables across sexually coercive (SEX), non-sexual conduct problem (CP), and normal control (NC) participants to identify general and specific risk/prote

Evaluation of Systolic and Diastolic Hypotension in Dementia with Lewy Bodies and Alzheimer’s Disease.

BACKGROUND: Orthostatic hypotension (OH) can be seen in as many as 30% to 50% of the elderly population as well as in dementia. OH is part of the autonomic dysfunction in dementia with Lewy bodies (DLB) and prevalent in the majority of these patients. It is also suggested to be a negative prognostic factor for survival in DLB. A detailed interpretation of the 10-minute orthostatic blood pressure m
