This study investigated the influence of various native and modified starches on the quality and staling behaviour of gluten-free bread. Four starch types: native wheat starch, cross-linked tapioca starch, fractionated native potato starch (FPS), and acetylated potato starch (Amylacetate) were evaluated by incorporating them into a standardized gluten-free bread formulation as the main starch sour

Polyhydroxybutyrate-co-valerate (PHBV), a biodegradable biopolymer, holds promise as a sustainable alternative to petroleum-based plastics. In this study, PHBV was biosynthesized and extracted, followed by an extensive evaluation of various downstream purification methods focusing on surfactant-based washing protocols. Different conditions of sodium dodecyl sulphate (SDS) washing varying in temper

Småhus med småskalig solproduktion och elbil kommer bidra med skarpa förändringar i elsystemet. Denna studie undersöker hur möjliggörande tekniker i form av smart laddning, Vehicle-to-Grid (V2G) och hembatterier samtsamhällsvetenskapliga påverkansfaktorer kommer vidare bidra till denna förändring. Studien visar att formen av styrande prissignalsamt utbredningsgraden av dessa tekniker kommer ha en The objective of this study is to investigate how the power profiles of residential houses in Sweden may look like in the future. Median power profiles for typical summer and winter days were created using real customer data. The customer group analyzed consists of houses in southern Sweden, SE4, equipped with both solar electricity production (PV) and electric vehicles (EVs) with home charging st

The increase in contact resistance within battery systems remains poorly understood, despite being one of the primary contributors to battery degradation. This project aims to investigate this phenomenon by modeling the electrical interface as a contact between a pin and a busbar. The main goal is to build a DOE and machine learning framework, using Bayesian optimization to efficiently explore the

EU aims to achieve climate neutrality in 2050, 23 cities in Sweden aim to reach that goal already by 2030. A new city district in Helsingborg - southern Sweden - is being developed with the goal of achieving near net-zero carbon emissions. This study evaluates the first completed phase and aims to draw learning outcomes to lower carbon emissions for the remaining upcoming development phases. The

This study investigated the sustainable extraction of protein from field cress (Lepidium Cam-pestre) press cake, an underutilized by-product of oil extraction from a novel oilseed crop, which is currently being domesticated in Sweden. Field cress is recognized for its resilience in Nordic climates and its potential as a source of sustainable aviation fuel (SAF), yet the protein and fibre-rich cake

This thesis explores the heterologous expression of six fungal enzymes with potential polyurethane (PUR) degrading activity in two strains of the filamentous fungus Aspergillus oryzae: the standard Ory6 and a knock-out variant with disrupted transcription factors to potentially reduce native protease activity. Each enzyme was expressed in three gene formats: a native version (including any introns

Trots ökad medvetenhet om digitala hot är svaga lösenord och lösenordsåteranvändning fortsatt vanliga, vilket äventyrar informationssäkerheten. Integrerade lösenordshanterare, som de inbyggda i webbläsare och operativsystem, erbjuder ett potentiellt verktyg för att stärka säkerhetsbeteenden, men användningen varierar kraftigt. Denna kvantitativa studie syftar till att undersöka hur dessa verktyg p

I brottmålsförfarandet förordnas ofta sakkunniga. Sakkunniga tillför domstolarna kunskap inom ett visst ämne. Domstolarna ska fastställa bevisvärdet av den sakkunnigas slutsatser, ofta utan egen kunskap inom ämnet. Psykologer är en typ av experter som ofta förordnas som sakkunniga. Slutsatser presenterade av psykologer tenderar att vara särskilt svårbedömda då den psykologiska disciplinen är komplExperts are commonly appointed in criminal cases to provide the court with relevant insight based on specialized knowledge within their area of professional experience. The court must determine the evidential value of the expert’s testimony, despite having little or no knowledge or training in the field of expertise. Conclusions provided to the court by psychologists tend to be particularly proble

Advokatyrket har en ovanlig plats i samhället. Advokater är inte statligt anställda men statligt reglerade, anses väsentliga för en demokratisk rättsstat och står under konstant granskning. Dessa förutsättningar ställer krav på advokaternas moraliska rättfärdighet och särskiljer yrket från gängse förtjänstorienterade konsulttjänster. Denna ställning i samhället kan ge intrycket av en sedan länge eThe legal profession holds a unique position in society. Lawyers are not government employees but are state regulated, considered essential for a democratic rule of law, and are under constant legal and public scrutiny. These conditions demand moral integrity from lawyers and distinguish the profession from typical profit-oriented consultancy services. This position in society might give the impre

Denna kandidatuppsats undersöker hur digitala lärverktyg används i teknikundervisning i mellanstadiet (årskurs 4–6), med fokus på lärares upplevda för- och nackdelar. Utifrån kvalitativ data baserat på semistrukturerade intervjuer med fyra mellanstadielärare som undervisar i teknik utforskar studien både hur digitala lärverktyg används i praktiken i klassrummet och hur organisatoriska förutsättnin

At the intersection of natural and social sciences, interest in river sedimentary fluxes and their alteration by human activities is increasing in the context of general retreat of delta formations. Since the 1950s, the construction of large dams in the main course of rivers has produced, among other impacts, a radical decrease in sedimentary fluxes — a key factor in the worldwide sedimentary cris

The history of hydraulic infrastructures is plagued with failures often with catastrophic consequences. Although the agency of water in disasters has been widely documented less well known are the substances in water such as salt that may cause infrastructural collapse and harm humans, flora and fauna. In the Llobregat River Basin (Barcelona), a 120-km long pipe transports salt-saturated wastewate

Debates on the total or partial privatization of water usually follow the rationale that efficient and rational management is best left to the private sphere. In this paper and using a historical example, we attempt to assess critically this assumption arguing that efficiency and rationality in resource management are and have been an asset of collective management as well. We present the case of

Combining historical climatology and environmental history, this article examines the diverse range of strategies deployed by the city government of Barcelona (Catalonia, NE Spain) to confront the recurrent drought episodes experienced between 1626 and 1650. Our reconstruction of drought in Barcelona for the period 1525-1821, based on pro pluvia rogations as documentary proxy data, identifies the
