The novel method of modification of polyethersulfone (PES) ultrafiltration membranes is proposed. This method involves the use of aqueous solutions of polyacrylic acid (PAA) of different molecular weights (Mn=5.1×103 g·mol–1, Mn=490×103 g·mol–1) as a coagulant in non-solvent induced phase inversion process (NIPS). Addition of PAA (0.05–1.5 wt%) to the coagulation bath leads to marked changes in pe

The incineration furnace at National Veterinary Institute (SVA) in Uppsala, Sweden, generates a large amount of waste heat. Some of this heat is partially recovered and is used for heating one of the main buildings during the furnace operation. However, around 2,000 MWh is wasted annually due to unavailability of any storage system. This work studies in detail four different solutions to utilize t

This study develops a framework for spatiotemporal modeling of dust storm source susceptibility in a critical case study, the Tigris-Euphrates River Basin, as a significant source of dust storms in the Middle East. The study period was divided into four periods, 2000–2004 (hydrological dry year), 2005–2007 (hydrological wet year), 2008–2012 (hydrological dry year), and 2013–2021 (hydrological wet

Eco-roofs are becoming popular for aesthetic reasons and also as units of stormwater systems. It is thought that such roofs with soil cover and vegetation reduces the total runoff, the peak flows and improves the quality of the roof water. Here are reported investigations of runoff from thin, 3-4 cm soil, extensive green roofs with sedum-moss in southern Sweden. The two-year study was performed on

Purpose: Although persistent offenders with histories of imprisonment and violence have disproportionate high rates of psychiatric disorders, little is known of their psychiatric healthcare utilization (HCU) and HCU-associated factors. This study aimed to explore psychiatric HCU, psychiatric morbidity, and psychotropic prescription drugs in violent offenders with a history of incarceration. Method

Introduction: The screening program for cervical cancer in Sweden recommends the use of primary human papillomavirus (HPV) screening for women aged ≥30 to 65 years. Co-testing with both HPV analysis and cytology is recommended at the first screening after the age of 40 years. To fulfil co-testing, all screened women aged 40–42 years within the region of Skåne were co-tested. The aim of the audit w

A new encapsulation strategy for probiotics is highly needed to tackle the challenge of significant viability loss of bacteria during storage and passage through the gastrointestinal system. A new controlled delivery system for probiotics based on EC oleogels is proposed in this thesis. A relatively non-complicated in vitro lipolysis model was established to evaluate the relative conversion from t

Background: Childhood cancer predisposition (ChiCaP) syndromes are increasingly recognized as contributing factors to childhood cancer development. Yet, due to variable availability of germline testing, many children with ChiCaP might go undetected today. We report results from the nationwide and prospective ChiCaP study that investigated diagnostic yield and clinical impact of integrating germlin

Coping with long-term suffering - Effects of Mindfulness-Based Stress Reduction (MBSR) on tinnitus distress Aim: To investigate whether the Mindfulness-Based Stress Reduction (MBSR) program increases mindfulness skills, reduces tinnitus distress and whether there is any correlation between them for the 71 respondents in the study. Methods: Out of 71 respondents with tinnitus distress starting th

This master thesis contributed to a project financed by the Swedish Energy Agency and managed by the housing company Eksta AB in collaboration with the consulting Company WSP. The main aim of this master thesis was to perform a theoretical optimization on the usage of own used solar electricity by transferring the surplus PV between buildings in a demonstration area in a DC-microgrid. To achieve th

Sett till EU:s totala koldioxidutsläpp står byggnadernas energianvändning för en tredjedel av dem (Regeringskansliet 2023). Sverige har ett energipolitiskt mål om att ha en 50 % effektivare energianvändning till 2030, jämfört med 2005, benämnt energiintensitetsmålet. En stor del av den befintliga bebyggelsen i vårt samhälle har ett högt energibehov. Med ökade krav på energieffektivisering av det bOne third of the EU's carbon emissions come from buildings energy use. Sweden aims for 50% more energy efficiency by year 2030, compared to year 2005. Existing buildings, with high energy demands, require renovations for energy efficiency. However, it is crucial to consider the climate impact of such upgrades. Window renovations are one option. This study explores the complexities of improving

This study used the urban context of Brunnshög, Sweden as a real case study to assess non-visual daylight conditions in urban environments. More precisely, the work was focusing on how the light spectrum – through surrounding façade colour and window type – can have an impact on the circadian potential. A one-bedroom apartment opening onto a courtyard on the ground floor and the same apartment on

Försörjning av varor och tjänster är en grundläggande del av ett fungerande samhälle, och stora delar av denna försörjning sker genom näringslivet och kritiska infrastrukturer. Hot i form av klimatförändringar och antagonistiska handlingar är centrala aspekter att beakta i utformningen av viktiga samhällsfunktioner för att kunna förebygga och hantera kriser. Under de senaste 10-15 åren har klimataThe supply of goods and services is a fundamental part of a functional society, and most of this supply is driven by businesses and critical infrastructures. In the shaping of vital societal functions, threats like climate change and antagonistic acts are central aspects to consider to prevent and manage potential crises. In the last 10-15 years, climate change adaption has become a tool for mitig

Adaptive reuse of existing buildings as a part of the circular economy principle has become a more common approach to promote sustainable development, due to increasing urban densification and environmental concerns. Ventilation systems, as a major contributor to energy use in buildings, often face complete replacement during building reconstruction, despite their potential for extended service li

En grundvattenundersökning i ett område präglat av vattenrelaterade problem. Staden Cochabamba i Bolivia står inför flera vattenrelaterade utmaningar såsom brist på ytvatten, en ökande vattenanvändning, urbanisering och en sjunkande grundvattennivå. Samtidigt råder det en brist på kunskap angående de processer som påverkar grundvattnet i området. Något som detta examensarbete ämnar att förändra. The Central Valley of Cochabamba is located in the Andes mountain range, Bolivia. This region experiences several water related challenges such as a scarcity of surface water, an increasing water demand, a growing urbanization in groundwater recharge areas, and a declining water table due to intensive groundwater extraction. The valley has been influenced by both alluvial and fluvial depositions t

Although a large volume of work has been conducted regarding tourism industries across the world, the dominant analysis in the geographies of tourism tends to draw upon post-modern discourse analysis and representational theories. This has resulted in calls to develop more materialist analyses of tourism landscapes. Using the case study of Long Bay, a small coastal settlement in Portland parish, J

With the emergence of industrialisation, the work-life balance has become a point of discussion in many industries, among which the aviation industry. Distortions in the work-life balance became especially apparent when 24/7 economies evolved, and industries made a transition to facilitate and serve these economies. Incidents and accident have since then been related to fatigue more than before. T

Climate change is a fact and the potential climate change impacts on infrastructure are necessary to examine to ensure the safety and performance of societies. The evidence for climate change is overwhelming, the changes have been observed and the projected future based on models indicate further change. Several of the climate change impacts are predictable, though the magnitude of the changes is

Hydropower is simply the largest source of renewable energy in the Nordic countries, where It compose around 90% of power production in Iceland, 70% in Norway, 40% in Sweden and 20% in Finland. Mountainous terrain and abundance in the surface water is a significant contributing factor in hydropower production. Hydropower is also considered more reliable and continuous than other forms of renewable

Background: Ischemia-reperfusion (I/R) in the intestines is an inflammatory condition which activates leukocytes and reactive oxygen species (ROS) and leads to lipid peroxidation and DNA damage. Bilberry and chokeberry fruits are rich sources of polyphenols which may act as antioxidants and prevent lipid peroxidation. Lactic acid bacteria (LAB) may improve microbial status in the intestines and in
