Advances in gear hobbing are driven to give higher cutting speeds, longer tool life and higher feed rates. Recently, a new type of hob with carbide inserts has been introduced with benefits in all these conditions compared to regrindable high speed steel hobs. However, with this kind of hob, new challenges occur due to positional errors of the cutting edges when mounted on the tool. These errors i

Popular Abstract in Swedish Allt fler människor drabbas av cancer, som idag är den ledande dödsorsaken globalt. De vanligaste cancerformerna i världen är lungcancer, bröstcancer och tjocktarmscancer och det är störst risk att dö i lungcancer, levercancer och magcancer. Även i Sverige ökar antalet cancerfall, till stor del på grund av att vi lever allt längre och cancer är idag en av våra stora folCancer incidence is increasing and it is the number one cause of death worldwide. Cancer is a highly heterogeneous disease and there is a great need for new early diagnostic, prognostic and treatment predictive biomarkers in order to improve patient outcomes. The RNA-binding motif protein 3, RBM3, is an emerging candidate biomarker of favourable prognosis and treatment response in several types of

Laurentia, the core of Paleo- to Mesoproterozoic supercontinent Nuna, has remained largely intact since assembly 2.0 to 1.8 billion years ago [Ga]. For earlier times, previous paleomagnetic data on poorly dated Paleoproterozoic mafic intrusions yielded ambiguous estimates of the amount of separation between key cratons within Nuna such as the Slave and Superior. Recent developments in paleomagneti

The AFm phase, one of the main products formed during the hydration of Portland and calcium aluminate cement based systems, belongs to the layered double hydrate (LDH) family having positively charged layers and water plus charge-balancing anions in the interlayer. It is known that these phases present different hydration states (i.e. varying water content) depending on the relative humidity (RH),

Complement activation occurs during inflammatory joint diseases such as rheumatoid arthritis (RA) and is thought to contribute to the chronic inflammation observed within the joints. Previous studies have shown that certain cartilage components of the small leucine-rich repeat protein (SLRP)-family regulate complement activity, thereby possibly contributing to disease progression. The aim of this

The Intermediate Data Structure (IDS) provides a common structure for storing and sharing historical demographic data. The structure also facilitates the construction of different open-access software to extract information from these tables and construct new variables. The article Using the Intermediate Data Structure (IDS) to Construct Files for Analysis (Quaranta 2015) presented a series of con

This study examines the influence of vortex core precession on flame flashback of swirl-stabilised hydrogen flames. Theoretical considerations suggest that the angular velocity of a swirling flow is reduced as vortex precession causes it to acquire an eccentric motion around the central axis of the burner. The eccentric motion of the vortex generates a secondary flow, which is thought to reduce th

This article presents results from 23 structured interviews focused on creative meetings (a crucial part of the definition being that something new is created in the meeting, through interaction between people). The interviewees represented many different fields of industry and academia, and together many hundred years of experience of meetings. Six main perspectives pertaining to creative process

Biochemical reactions powered by ATP hydrolysis are fundamental for the movement of molecules and cellular structures. One such reaction is the encapsidation of the double-stranded DNA (dsDNA) genome of an icosahedrally symmetric virus into a preformed procapsid with the help of a genome-translocating NTPase. Such NTPases have been characterized in detail from both RNA and tailed DNA viruses. We p

Objectives - In patients with large middle cerebral artery (MCA) infarcts, maximum brain swelling leading to cerebral herniation and death usually occurs 25 days after onset of stroke. The study aimed at exploring the pattern of compounds related to cerebral energy metabolism in infarcted brain tissue. Methods - Forty-four patients with malignant MCA infarcts were included after decision to perfor

The PreSPEC setup for high-resolution 'gamma-ray spectroscopy using radioactive ion beams was employed for experimental campaigns in 2012 and 2014. The setup consisted of the state of the art Advanced GAmma Tracking Array (AGATA) and the High Energy gamma cleteCTOR (HECTOR+) positioned around a secondary target at the final focal plane of the GSI FRagment Separator (FRS) to perform in-beam gamma-r

Paracetamol is the most commonly used over-the-counter drug in pregnancy. It is generally considered to be safe, but prolonged antenatal exposure has been associated with offspring short- and long-term morbidity. Our aim was to describe the pattern of paracetamol use with a focus on frequent ingestion (more than once a week), 3months before and in early pregnancy. In this cohort, 8650 pregnant wom

Smoking, diabetes, male sex, hypercholesterolaemia and hypertension are well-established risk factors for the development of coronary artery disease (CAD). However, less is known about their role in influencing the outcome in the event of an acute coronary syndrome (ACS). The aim of this study was to determine if these risk factors are associated specifically with acute myocardial infarction (MI)

Background In many scientific domains, it is becoming increasingly common to collect high-dimensional data sets, often with an exploratory aim, to generate new and relevant hypotheses. The exploratory perspective often makes statistically guided visualization methods, such as Principal Component Analysis (PCA), the methods of choice. However, the clarity of the obtained visualizations, and thereby
