Efforts to reduce greenhouse gas emissions, globalized markets with intense competition, and generally rising transportation costs emphasize the importance of achieving economically and environmentally sustainable distribution systems. Many international organizations predict that if no new measures are implemented, global carbon dioxide emissions from freight transport will increase to even highe
Unpigmented skin cancer is the most prevalent form of cancer, and it burdens healthcare substantially even if it is not as aggressive as the more well-known malignant melanoma. Dermatoscopy images are commonly used for diagnosis, but differentiating between the many sub-diagnoses is a hard task. In this study we focus on these unpigmented cancers, performing both detection of basal cell carcinoma
High humidity, high ash content and low heating values are the major disadvantages of using lignite without ant pretreatment. High moisture content and low energy density make some of the biomass resources disadvantages in direct energy production. In this thesis, the main aims to reduce the disadvantages of both sources and obtain fuel with different structural/physical properties by hydrothermal
The many challenges of our time call for changes in regional economies, increasingly motivating scholars to dive deep into the mechanisms and possibilities for delivering such change. However, the link between regional change and people’s well-being has often been neglected, assuming that new job opportunities, green industrial path development, or higher-value economic activities are inherently g
It is an open question whether small planets around M dwarfs are able to maintain atmospheres. The Hot Rocks Survey aims to address this question by observing nine rocky exoplanets orbiting M dwarfs with MIRI emission photometry to constrain the onset of atmospheres. In this paper, we present two MIRI F1500W (15 μm) eclipses of LTT 3780 b, an ultrashort-period super-Earth (P = 0.768 days, R = 1.32
Traffic accidents cause over 1.2 million deaths, and tens of millions of people are injured or disabled every year. Advanced driver assistant systems and other safety features have the possibility to reduce traffic accidents but do not account for human errors. Studies show that over 90% of all traffic accidents are caused by human errors. One way to reduce human errors is to introduce automation,
Employment is a potential socioeconomic co-benefit of renewable energy deployment. However, renewable energy is often more expensive than conventional resources, putting pressure on the economy, and during an energy transition employments can be lost from the conventional energy sector, e.g. from phased out nuclear plants. The purpose of this study was to clear the field of whether a promotion of
The origin of many environmental and health hazardous emissions from diesel engines are the crankcase gases. Since no regulations of the emission levels from the crankcase have existed in the past, no attention has been paid to cleaning crankcase gases. New regulations are coming up and they will all demand lower emissions from the engine. This has lead to the introduction of the Alfdex separator.
In 2012 the Swedish government decided that Sweden’s first high speed rail shall be constructed. The railway is titled Ostlänken and forms a part of a potential high speed rail network. It also sets the technical standard for the new network, and therefore the possibility to improve technical solutions should be evaluated. The Swedish power supply system currently in use differs from the internati
With the sustainable potential of the city as a starting point, this thesis examines brownfield redevelopment in an existing urban context. The Nørrebro neighborhood of Copenhagen serves as a case. The focus is on learning from and reinterpreting existing urban structure, hierarchy, density and scale. Legislation allowing car free development at the chosen site, Vingelodden, also prompts explorati
The thesis investigates the perceptions about the importance of sustainability issues in the Millennial generation and the connection of the results to sustainability accounting to show how useful it is. The focus is particularly on sustainability as a criterion for job decisions and the extent to which it influences the motivation at work. In addition, differences in perception about age, gender,
Europeiska unionen har länge arbetat för att uppnå fri rörlighet på den inre marknaden. På de flesta områden har arbetet nått långt men det finns undantag. Hypotekslånemarknaden inom EU är, trots betydande ekonomisk storlek, inte harmoniserad och ett flertal hinder mot den fria rörligheten av kapital existerar. Fokus i uppsatsen ligger framförallt på harmonisering och införande av en europeisk hThe European Union has long worked to achieve free movement within the internal market. In most areas, work has come a long way but there are exceptions. The mortgage market in the EU, despite significant economic size, is not harmonized, and a number of obstacles to achieve free movement of capital exist. The focus of the essay is primarily on the harmonization and implementation of a European
Despite the fact that men dominate substance abuse research and that most programs to target substance abuse therefore are developed by and for men, very little is known about the fact that substance abusing men can also be parents. Mothers are up until today regarded as the most important parent even though society is changing and fathers are taken a more active part in childrearing. The average
Purpose: This paper aims to uncover the associations and expectations consumers develop from a brand taking a political or social stance. We build upon existing literature to offer managers, and the research field, valuable insights to bridge the knowledge gap on what to consider before taking a stance. This paper guides the reader through a set of key considerations to evaluate before taking acti
BACKGROUND: The early detection of circulatory failure in patients with sepsis is important for successful treatment. Heparin-binding protein (HBP), released from activated neutrophils, is a potent inducer of vascular leakage. In this study, we investigated whether plasma levels of HBP could be used as an early diagnostic marker for severe sepsis with hypotension. METHODS: A prospective study of 2
Eighty basal cell carcinomas (BCCs) in 21 patients, 10 lesions of Bowen's disease in three patients, and four lesions of cutaneous T-cell lymphoma in two patients, were treated with photodynamic laser therapy (PDT), using topical application of the haem precursor delta-amino levulinic acid (ALA). The diagnoses were confirmed histologically prior to treatment. Fifty-five of the BCCs were superficia
Welding fumes include agglomerated particles built up of primary nanoparticles. Particles inhaled through the nose will to some extent be deposited in the protein-rich nasal mucosa, and a protein corona will be formed around the particles. The aim was to identify the protein corona formed between nasal lavage proteins and four types of particles with different parameters. Two of the particles were
OBJECTIVE:: The aim of the trial was to compare laparoscopic technique with open technique regarding short-term pain, quality of life (QoL), recovery, and complications. BACKGROUND:: Laparoscopic and open techniques for incisional hernia repair are recognized treatment options with pros and cons. METHODS:: Patients from 7 centers with a midline incisional hernia of a maximum width of 10 cm were ra
Working as hairdressers has been associated with increased risk for cancer, particularly bladder cancer. To evaluate if current hairdressers have elevated risks of adverse health effects, we measured several biomarkers related to cancer-related DNA alterations. We enrolled 295 hairdressers and 92 non-hairdressers (all female non-smokers) from Stockholm and southern Sweden. Questionnaire data were
Objective Nocturnal gastroesophageal reflux (nGER) has been associated with respiratory diseases. Our aim was to study a questionnaire method to identify nGER subjects with respiratory involvement in a general population. Material and methods A subgroup of Icelandic participants in the European Community Respiratory Health Survey III (ECRHS III) reporting symptoms of nGER (n = 48) as well as age a
