The objective of this report was to investigate different types of glass when exposed to heat radiation from a typical fire in a dangerous goods carrier. The purpose was to evaluate if tempered glass could be used in facades instead of the more expensive fire resistant glass. Experiments were made in a cone calorimeter where different thicknesses of laminated, tempered and fire resistant glass wer
Lime-hemp concrete is an old insulation material, made out of hemp shiv and lime, making its way back onto the market. This thesis focuses on the usage of lime-hemp as an alternative insulation material for restoration of older wooden buildings in the town of Visby in Gotland, Sweden. The aim of this report is to investigate fire resistance properties of lime-hemp concrete and to compare it to oth
Coastal areas around the world are being shaped by many natural phenomena, as well as by man-induced activities. Hydrodynamic phenomena such as wind-generated waves, extreme storms and seasonal tides cause a continued change in topography and the natural sediment formation in the nearshore zone as a result of erosion and accumulation. Therefore, the nature of the nearshore zone and its protection
Many industries, which are producing sludge in large quantities, depend on sludge dewatering technology to reduce the corresponding water content. A key design parameter for dewatering equipment is the capillary suction time (CST) test, which has, however, several scientific flaws, despite that the test is practical and easy-to-perform. The standard CST test has a few considerable drawbacks: its l
In the last century, starch present in foods was considered to be completely digested. However, during the 1980s, studies on starch digestion started to show that besides digestible starch, which could be rapidly ors lowly hydrolysed, there was a variable fraction that resisted hydrolysis by digestive enzymes. That fraction was named resistant starch (RS )and it encompasses those forms of starch t
A double burden of malnutrition occurs when individuals, household members or communities experience both undernutrition and overweight. Here, we show geospatial estimates of overweight and wasting prevalence among children under 5 years of age in 105 low- and middle-income countries (LMICs) from 2000 to 2017 and aggregate these to policy-relevant administrative units. Wasting decreased overall ac
Nonparametric efficiency analysis has become a widely applied technique to support industrial benchmarking as well as a variety of incentive-based regulation policies. In practice such exercises are often plagued by incomplete knowledge about the correct specifications of inputs and outputs.

Recently, the number and amount of biogenically emitted volatile organic compounds (VOCs) has been discussed in great detail. Depending on the ecosystem, the published number varies between a dozen and several hundred compounds. We present ecosystem exchange fluxes from a mixed oak–hornbeam forest in the Po Valley, Italy. The fluxes were measured by a proton transfer reaction-time-of-flight (PTR-T
Purpose - To offer knowledge about the global development of largescale demand responsive transport systems (DRT), and to stimulate dialogue and collaboration for further innovation and improvement of these systems. Design/methodology/approach - A review of the literature shows how DRT has evolved from the first applications in the 1970s to very complex operations in the last two decades with hund
Aim: The Swedish Social Board has implemented a support strategy to guide out-of-home care for children, which translates as children's needs in focus (CNIF) and includes a systematic health assessment. It was fully introduced into the Skåne province in 2012 and our study covered the first four years of the CNIF health assessments, from 2012 to 2015. Methods: We studied children aged 0–17 years in
The aim of this study was to investigate calcium chloride-induced gelatinization of oat starch, and its effects on the properties of oat starch-based Pickering emulsions. The starch granules were gelatinized in CaCl2 for up to 24 h and the results indicate that the salt-induced gelatinization of oat granules is not a surface phenomenon, as gelatinization and dissolution of the whole starch granule
In the presence of ouabain (1 mM), acetylcholine and KCl (5 mM) evoked endothelium-independent relaxations in rat hepatic arteries. Treatment with capsaicin (10 μM), scopolamine (1 μM) or CGRP8-37 (3 μM) prevented these relaxations. Acetylcholine-induced relaxations in intact arterial segments in the presence of indomethacin (10 μM) and N(G)-nitro-L-arginine (0.3 mM) were only partially inhibited
The Intergovernmental Panel on Climate Change (IPCC) has provided periodic assessments of the state of knowledge on climate change for 30 years. While these assessments have been central to the making of international climate policy, their relevance has been questioned in the post-Paris era. Can the IPCC's global kinds of knowledge match the demands of an increasingly decentralized and polycentric
In the context of complex intergenerational challenges such as climate change and sustainable development, it is increasingly important for scientists and policy-makers to actively engage with and support the meaningful participation of youth in policy and decision-making. This research evaluates the effectiveness and impact of the Youth in Landscapes Initiative in supporting the active participat
Background: We have previously reported quantitative exposure-response relationships between physical exposures recorded by technical methods, and complaints and diagnoses in the neck/shoulders, and the elbows/hands, based on group data. In the present study the number of workers was doubled, and information on individual factors, and psychosocial working conditions was used. Relationships between
Objective: Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is associated with life-threatening bleeding. This systematic review of postnatal management of FNAIT examined transfusion of human platelet antigen (HPA) selected or unselected platelets, and/or IVIg on platelet increments, hemorrhage and mortality. Study design: MEDLINE, EM
The possible association between stress-related exhaustion and reduced activity in the hypothalamo-pituitary-adrenal (HPA) axis is increasingly in focus. The aim of the present study was to examine whether exhaustion measured in a non-patient population is associated with alterations in diurnal cortisol profile. The study population included 78 working individuals. The study group was dichotomised
This randomized trial evaluates whether automated telephony could be used to perform daily assessments in paroled offenders (N = 108) during their first 30 days after leaving prison. All subjects were called daily and answered assessment questions. Based on the content of their daily assessments, subjects in the intervention group received immediate feedback and a recommendation by automated telep
Developing correlations between various soil parameters are considered the major challenge to diminish time and cost associated with field measurements. Soil hydraulic and physical properties were extensively characterized using tension disc infiltrometer and soil sampling in a silty clay agricultural field in Kalaat El-Andalous, Tunisia. Tension disc infiltrometer experiments were conducted at 10
Until recently, the only way to describe microbial communities was by cultivation. This is a major obstacle because typically only a small fraction of the microbes can be cultivated by standard techniques. However, the use of rRNA and molecular phylogenetic techniques has allowed us to bypass this limitation. In this thesis, both of these approaches were used to describe the bacterial diversity o
