Experimental investigation of microscale mechanisms during compressive loading of paperboard

Compression of paperboard is a common procedure during industrial package forming and better knowledge of the material response is needed to avoid defective packages and waste. To go beyond current modelling approaches, experimental identification of mechanisms underlying the macroscopic stress–strain responses is needed. In this study, in-situ uniaxial compression of paperboard is studied through

Habitat area and local habitat conditions outweigh fragmentation effects on insect communities in vineyards

Fragmentation of habitat, for example by intensive agricultural practices, can be detrimental to local biodiversity. However, it often remains unclear whether such biodiversity declines are caused by loss of habitat area or increased fragmentation, and how habitat quality factors into it. In our study system, vegetated vineyards are typically small, and isolated from one another, potentially limit

Spatial and temporal wave climate variability along the south coast of Sweden during 1959–2021

This study presents 62 years of hindcast wave climate data for the south coast of Sweden from 1959–2021. The 100-km-long coast consists mainly of sandy beaches and eroding bluffs interrupted by headlands and harbours alongshore, making it sensitive to variations in incoming wave direction. A SWAN wave model of the Baltic Sea, extending from the North Sea to the Åland Sea, was calibrated and valida

Konjunkturrådets rapport 2018. Kapitalbeskattningens förutsättningar

I rapporten från SNS Konjunkturråd 2018 analyserar och diskuterar tre nationalekonomer kapitalbeskattningens förutsättningar i Sverige. Författarna finner brister i kapitalinkomsternas beskattning och föreslår en enhetligare beskattning. De förespråkar också en löpande fastighetsskatt för både småhus och bostadsrätter men lägre skatt på omsättning av fastigheter. Rapporten pekar också på att en sk

Arktis, en plats för både soft och hard power?

The Arctic is a changing place where the melting of the ice creates new opportunities and shipping lanes, such as Northern Sea Route and possibility for raw material extraction. However, this prospects can also be a road to conflict. Russia and China are very active in the area with both soft and hard power, where China has focused on values, research and cooperation and Russia puts efforts on its

Ett gott ledarskap – viktigast på Första Ubåtsflottiljen

The First Submarine Flotilla is expanding. Four submarines are to become five and a new, larger signal intelligence ship is to replace the current one. At the same time many employees are on the verge of retiring and new ones in need of training arrives. It is therefore of utmost importance that the existing staff want to remain in their workplace. The purpose of this study was, through a survey b

Har mellanmänsklig tillit påverkan på människors hemberedskap?

In a recent survey made on behalf of The Swedish Civil Contingencies Agency it shows that 37 per cent of the Swedish population meet the governmental recommendations about civilian readiness during a societal emergency. In a different survey about interpersonal trust the results show that approximately 40 per cent of the people in Sweden do not feel high levels of trust towards others. This st

Small but mighty: Learning outcomes and impacts of microplastic focused citizen science

Microplastics are a present and future threat to the sustainability of coastal socio-economic systems. Current solutions and management could be improved by developing citizen science programs to foster community engagement and knowledge generation. However, research is limited on the actual learning outcomes and impacts of citizen science. To help close this gap, this research builds upon existin

Particle identification in the low-GeV/c regime using Octafluoropropane (R-218) as Cherenkov radiator

Particle identification with threshold Cherenkov detectors, using a moderately pressurized radiating gas with an adequate refractive index, is one of the most common techniques employed in high-energy physics. However, available gases with relatively high refractive indices, that simultaneously preserve their gaseous phase at room temperature and moderate pressures, are rare. Until recently, R-12

Hållbarhet, en kostnad eller en möjlighet? En kvantitativ studie om relationen mellan riskjusterad avkastning och hållbarhet hos de fem största GICS sektorerna inom euroområdet

Relationen mellan hållbarhet och riskjusterad avkastning har intresserat akademiker och investerare länge. Denna uppsats ämnar dels att studera hurvida investerare kan använda hållbarhetsinformation för att öka den riskjusterade avkastningen inom olika sektorer, dels att undersöka om skillnader går att observera sektorer emellan. Vi undersöker de fem största GICS-sektorerna inom euroområdet: Healt

Understanding Areas of Parallelograms Through Virtual Geometrical Representations : A Pilot Study

Do virtual representations, intended for teaching and learning, afford different constraints and affordances compared to their physical twins, and may this lead to different ways of interaction and understanding? In this line of inquiry, and with the perspective on learning as an extended activity, where learning can be mediated through the interaction with artefacts, the present study has transla

Interaction between vitamin D deficiency and COVID-19

Coronavirus Disease 2019 (COVID-19) poses an enormous challenge to health care systems throughout the world, but it doesn’t affect every individual to the same extent. There is great variability in disease outcomes. Therefore, identifying the main prognostic risk factors is of paramount importance. These include increased age, skin pigmentation, obesity, pre-existing illness, and vitamin D deficie

Civilplikten åter aktuell?

Civil conscription was a way to supply personnel for the civilian part of Swedish total defence. In 2010, the Swedish government chose to replace civil conscription with voluntary service. However in 2023, 13 years after the decision, it seems as reactivation is underway as the Swedish Civil Contingencies Agency (MSB) has been tasked to prepare for the activation of civil conscription for municipa

Survival of the Un-Fittest? A Study of Social Media-Based New Crisis Initiatives in the COVID 19 Pandemic

Focusing on Sweden in the COVID 19 pandemic, this paper explores theorganizational/communicational practices of new crisis initiatives, defined as informal,emergent, and loosely coordinated interactions between individuals and/or organizations using social media to engage in crisis relief efforts. By manually tracing crisis relief efforts on Facebook in the spring of 2020 and the fall of 2021, we

The verification of wildland–urban interface fire evacuation models

This paper introduces a protocol for the verification of multi-physics wildfire evacuation models, including a set of tests used to ensure that the conceptual modelling representation of each modelling layer is accurately implemented, as well as the interactions between different modelling layers and sub-models (wildfire spread, pedestrian movement, traffic evacuation, and trigger buffers). This w

Outpatient vs inpatient induction of labor with oral misoprostol : A retrospective study

Introduction: Induction of labor is one of the most common obstetrical procedures today, with a successively rising rate. With a limited number of hospital beds, the option of starting induction at home has gained increasing attention. The primary aim of this study was to compare the proportion of women achieving vaginal delivery and the duration of hospital stay before delivery in induction of la
