We used the nation-wide Swedish Family-Cancer Database to examine the familial risks of histology-specific bone cancers in offspring by parental or sibling probands. Adjusted standardised incidence ratios (SIRs) were used to measure the risk. Among the 1327 offspring bone cancers, only two parent-offspring pairs and one sibling pair were noted with concordant bone cancer but the SIRs were not sign
Although many studies have examined the associations between occupational exposures and kidney cancer, the evidence is not consistent. To examine the risk of occupational exposures on kidney cancer, we carried out a follow-up study on the economically active Swedish population, based on the latest update of the Swedish Family-Cancer Database. We calculated standardized incidence ratios (SIR) and 9
Cyanobacteria in fresh water can cause serious threats to drinking water supplies. Managing cyanobacterial blooms particularly at small drinking water treatment plants is challenging. Because large amount of cyanobacteria may cause clogging in the treatment process and various cyanotoxins are hard to remove, while they may cause severe health problems. There is lack of instructions of what cyanoba
This study suggests an optimization framework to plan and design a network of bike lanes in an urban context, based on equity principles and subject to a given available budget. The novelty of the proposal consists in an objective function that aims at minimizing the existing inequities among different population groups in terms of accessibility/opportunity to the bikeways. The proposed methodolog
The essay argues that between the world we aim to study and the realities we describe there is no straight, neutral relation. Instead, through our scientific practices we simplify that world as well as contribute to shape it. Methods are not mere procedures to mirror the world; rather, methods mediate between the world and our descriptions of it, and in the process they contribute to both simplify
In type 1 diabetes, pancreatic beta cells are destroyed by chronic autoimmune responses. The disease develops in genetically susceptible individuals, but a role for environmental factors has been postulated. Viral infections have long been considered as candidates for environmental triggers but, given the lack of evidence for an acute, widespread, cytopathic effect in the pancreas in type 1 diabet
We considered nonlinear solvers inside implicit time integration schemes for the time dependent compressible Navier-Stokes equations. The existing solvers turn out to be adequate, but amenable to significant improvements. Regarding multigrid schemes, we demonstrated that reoptimizing a multigrid scheme for the case of a time dependent equation leads to significant improvements in convergence speed
This paper presents a cryptographic processor compliant with the security algorithms specified by the 3rd Generation Partnership Project (3GPP) specifications for Long Term Evolution (LTE). The proposed processor has been adapted to the needs of the low end portfolio technologies that compose the Internet of Things (IoT) market, which addresses low-Area, low-cost and low-data rate applications. Th
OBJECTIVE: To present findings that suggest steroid treatment within 24 hours of onset of vestibular neuronitis results in better restitution of vestibular function than treatment between 25 and 72 hours. PATIENTS: Thirty-three consecutive patients (17 men, 16 women, mean age 57 yr, range 17-85 yr) with acute vestibular neuronitis and treated with steroids within 72 hours after symptom onset. Pati
Objectives: The purpose of this study was to modify a clinical linear accelerator, making it capable of electron beam ultra-high dose rate (FLASH) irradiation. Modifications had to be quick, reversible, and without interfering with clinical treatments. Methods: Performed modifications: (1) reduced distance with three setup positions, (2) adjusted/optimized gun current, modulator charge rate and be
Phased array antennas are cornerstones in many proposed antenna solutions concerning the next generation of both airborne radar systems and wireless communication systems (5G). Additionally, millimeter wave (mm-wave) frequencies are expected to play an integral role in 5G, and are deemed well-suited for inspecting structural components used in the aerospace industry.This dissertation consists of a
Aims. We aim to measure lifetimes of levels belonging to the 3d 3 ( 4 F)4d subconfiguration in Va II, and derive a
Different virtual reality (VR) experimental tools and equipment are available for evacuation research, ranging from highly immersive systems such as cave automatic virtual environments (CAVEs) to head-mounted displays (HMDs). In particular, mobile-powered HMDs are an extremely cost-efficient solution, for which the research potential for evacuation studies needs to be assessed. This study compares
Some theoretical approaches are reviewed to analyze crystallographic and optical properties of phosphors for white light emitting diodes. Stresses are placed on 1) local electro-neutrality for the structural stability of hosts, and 2) dielectric property and coordination of anion ligands around rare-earth luminescent centre for the tuning of emission colour. First-principles calculation results ar
We consider least-squares approximation of a function of one variable by a continuous, piecewise-linear approximand that has a small number of breakpoints. This problem was notably considered by Bellman who proposed an approximate algorithm based on dynamic programming. Many suboptimal approaches have been suggested, but so far, the only exact methods resort to mixed integer programming with super
This article reports findings from a study of weaning from a perspective informed by practice theory. The overall aim is to examine how parents integrate convenience baby food into their everyday feeding practices. The focus is the embedding of convenience baby foods in the routines and rhythms of everyday life and the “do-ability” of different practices. The study is based on fieldwork with ninet
