Thermal actions are considered in the design of bridges, as temperature variations can lead to restraint stresses and subsequent cracking. However, load descriptions are in some cases oversimplified or incompatible with modern applications, and background studies are limited. This paper therefore aims to develop a more detailed load description for the load case describing temperature differences

Denna rapport sammanfattar några studier som på olika sätt syftar till att förbättra metodiken för att analysera samhällsekonomiska effekter av kollektivtrafikinvesteringar. Förbättringarna som behandlas är 1) vikten av att ta med bristande kapacitet (trängsel) i kalkylerna; 2) förbättrade beräkningar av driftskostnader; 3) effekter av tillgänglighet på arbetsmarknad och produktivitet (s k ”wider

Hösten 1971 släppte en ny grupp från Malmö, Hoola Bandoola Band, sitt första album, Garanterat individuell, vilket kom att få stor spridning och innebära gruppens genombrott i den svenska populärmusikgenren. En av de sånger som har kommit att göra albumet ihågkommet genom flera decennier är Fred (Till Melanie)skriven av Mikael Wiehe. Den drygt 13 minuter långa sången avslutar albumet och är av när

Våra städer är otroligt sårbara för skyfall. Skyfallen som drabbade Köpenhamn 2011 och Malmö tre år senare blev en ögonöppnare för många. I vår artikel presenterar vi resultaten från en intervjustudie där flera nyckelpersoner i Sverige, Danmark och Norge har fått besvara frågor relaterade till skyfallshantering. Den generella uppfattningen hos de som intervjuats i denna studie är att det saknas st

Separately collected urine is an attractive potential fertilizer because of its high nutrient content, low cost, and inherent linkage of urban wastewater management and peri-urban agriculture. Urine from waterless urinals was applied to corn and lettuce plants to examine the impact of urine application rates and frequency on plant growth and soil parameters. In both corn and lettuce experiments, u

This article aims to demonstrate that building envelopes can be designed to improve the performance of public open space in Hong Kong. It investigates how such improvement can be used to negotiate between objective and regulation in planning standards. Addressing a research site with a publicly accessible pocket park in the Mong Kok area, the article explores generative potentials at the interface

The present study was undertaken to correlate calcium accumulation with the development of neuronal necrosis following transient ischemia. After 10 min of forebrain ischemia in the rat—a period that leads to reproducible damage of CA1 pyramidal cells—determination of calcium concentration and evaluation of morphological signs of cell body necrosis in the dorsal hippocampus were performed at variou

Purpose – The purpose of this paper is to explore in what way gradually increasing teachers’ theory-based instruction affects the students’ learning outcomes, illustrated by the example of learning how to regulate body tension in the upper secondary school. Design/methodology/approach – In total, 72 students from four classes participated in the study. The way the students were offered to understa

In this paper, the connection between the Matérn kernel and scale mixtures of squared exponential kernels is explored. It is shown that the Matérn kernel can be approximated by a finite scale mixture of squared exponential kernels through a quadrature approximation which in turn allows for (i) state space approximations of the Matérn kernel for arbitrary smoothness parameters using established sta

Epidemics and pandemics are associated with a variety of life-threatening conditions and have serious effects on physical as well as mental wellbeing. The Covid-19 pandemic raised the same difficulties for public and private sectors including schools, businesses, healthcare sectors, etc. The disease, which originated in Wuhan, China in December 2019, has ravaged nearly every country in the world.
