Long-span floors are particularly sensitive to footfall-induced vibrations, making their analysis and design critical for ensuring occupant comfort. Cross-laminated timber (CLT) panels have high stiffness relative to their self-weight and are commonly made of spruce. Hardwoods such as birch and beech possess higher stiffness and mass density, which can potentially improve the vibrational performan

Softwood species are the most commonly used species in structural applications in north-ern Europe. However, in the last couple of years, utilization of hardwoods has gatheredincreased momentum, and different hardwood species, such as birch, have even been uti-lized in cross laminated timber and glued laminated timber [1]. In general hardwoodsshow an increase in strength and stiffness as compared

Background: Medical student master’s theses are often carried out as research projects, and some are published as research papers in journals. We investigated the percentage of master’s theses conducted by 5th -year students at the Medical Degree Program at Lund University, Sweden, that subsequently served as the basis for research publications. In addition, we explored both student and supervisor

Climate change is expected to increase the frequency and intensity of extreme weather events. Individualized and timely advice on how to cope with thermal stress is therefore needed to encourage protective strategies and reduce morbidity and even mortality among vulnerable populations. Such advice can be based on integration of human thermal models, weather forecasts and individual user characteri

Sveriges neuro­psykologers förening: Ökningen av adhd-diagnoser är ett samhälls­problem som inte kan lösas enbart av vården, och lösningen finns knappast i en växande mängd av utredningar, diagnoser och medicinering.

Patientsäkerheten är hotad vid neuropsykiatriska utredningar, och främst gäller det adhd och autism. Alltför snäva tidsramar ger inte utrymme för den noggrannhet som krävs vid utredningar, skriver flera debattörer.

PURPOSE: The aim was to study the association between dietary intake of B vitamins in childhood and the risk of islet autoimmunity (IA) and progression to type 1 diabetes (T1D) by the age of 10 years.METHODS: We followed 8500 T1D-susceptible children born in the U.S., Finland, Sweden, and Germany in 2004 -2010 from the Environmental Determinants of Diabetes in the Young (TEDDY) study, which is a p

Biografisk artikel om Dagmar Karlberg (1866-1845), Kalmars första och Lunds universitets sjuttonde studentska, fil lic i matematik men främst verksam som "utländsk korrespondent" och översättare, känd för att ha kunnat 28 språk.

This article presents an online survey with 323 respondents and 28 semi-structured interviews performed to investigate people’s perceptions of fire evacuation training and their attitudes towards it. The survey results showed that respondents with experience in fire evacuation training judge a fire in buildings that feature non-combustible materials to be more severe than other people, but no effe

The question of the rationality of conspiratorial belief divides philosophers into mainly two camps. The particularists believe that each conspiracy theory ought to be examined on its own merits. The generalist, by contrast, argues that there is something inherently suspect about conspiracy theories that makes belief in them irrational. Recent empirical findings indicate that conspiratorial thinki

Blinks, the closing and opening of the eyelids, are used in a wide array of fields where human function and behavior are studied. In data from video-based eye trackers, blink rate and duration are often estimated from the pupil-size signal. However, blinks and their parameters can be estimated only indirectly from this signal, since it does not explicitly contain information about the eyelid posit

The present paper investigates the impact of different water penetration criteria on the risk for damage in a common type of building envelope in Nordic countries, timber frame walls with brick masonry veneer. The studied walls are evaluated based on one damage criterion, the risk of mold growth. The study investigates several parameters: water penetration criterion, type of moisture source (unifo

This article introduces a novel testing system for investigating rock hydromechanical behavior with neutron and X-ray imaging techniques. The system comprises four subsystems: an axial compression system, a confining pressure system, a fluid flow system, and a triaxial cell. In order to enable imaging with both modalities to track fluid flow and deformation in situ and 3D, the cell was designed to

Engineering energy storage/extraction for geoenergy applications (e.g., geothermal energy extraction, CO2 and/or Hydrogen storage) requires a very good knowledge of subsurface heterogeneities. One of the principal factors that influences the response of the underground system is the continuously evolving pore networks of the targeted rocks. This work aims to understand the pore network of a natura

This research study investigates the response of clay brick masonry with different crack widths before and after repointing subjected to water spray. In doing so, 3-course masonry prisms containing artificial cracks were exposed to a water spray during 23 hours of testing. Forty-nine cracked 3-course masonry prisms were prepared with a crack width varying between 0.3 mm and 0.9 mm, whereas thirtee
