Achieving a robust ignition with minimal spark plug wear is challenging in heavy duty engines fueled with gaseous fuels like biogas and hydrogen. Thermal energy deposition from the spark to the gas was studied in a 10.9 milliliter custom-built spark calorimeter. An AC capacitive ignition system was used along with a dual-nickel standard J-gap spark plug and the influence of multiple physical and e

BACKGROUND: This study sought to characterize a cohort of talar neck and body fractures, focusing on fracture characteristics, associated injuries, treatment and outcome.METHODS: We reviewed adult patients registered in the Swedish Fracture Register 2011-2021 with talar neck and body fractures. A minimum 2-year follow-up was conducted for treatment outcomes.RESULTS: We included 313 patients (318 f

Som en reaktion på Rysslands fullskaliga invasion av Ukraina har EU och allierade G7-länder infört omfattande sanktioner riktade mot rysk olja och petroleumprodukter. För att kringgå dessa sanktioner har Ryssland i allt större utsträckning förlitat sig på en parallell flotta – en så kallad skuggflotta – som har kommit att spela en betydande roll i finansieringen av den ryska krigföringen. SkuggfloIn response to Russia’s full-scale invasion of Ukraine, EU and allied G7 countries implemented extensive sanctions regimes targeting Russian oil and petroleum products. To circumvent these sanctions, Russia has increasingly relied on a parallel fleet operating without Western ties – a shadow fleet – which has come to play an important role in funding the Russian war effort. Shadow fleet vessels em

Hard-to-heal wounds are a growing human and financial concern, constituting approximately 1–3% of the healthcare budget. Wound care is not a medical specialty and is often not prioritized within healthcare. A large portion of the cost and suffering caused by wounds has the potential to be mediated through improved knowledge and effectivised workflows. One potential way to achieve this is through t

Collective action problems emerge when individual incentives and group interests are misaligned, as in the case of climate change. Individuals involved in these problems are generally considered to have two options: contribute toward public solutions such as global warming mitigation or free ride. However, many collective action problems today involve a third option of investing in a “private solu

This thesis analyses if macroeconomic policy has asymmetric effects on output and unemployment, comparing the effectiveness of monetary policy when the output gap is positive to when it is negative. Asymmetric effects may be present due to uncertainty and loss aversion, the downward-stickiness of prices, or financial market imperfections. The empirical analysis is conducted through a panel data re

Analyzing Baltic trade pattern confirms that the economic transition, following the fall of the Soviet Union, largely involves a regional integration process with western Europe. This thesis examines the trade patterns of the three Baltic States (Estonia, Latvia, Lithuania) focusing on the regional integration process with the EU. The objective is to investigate the trade relations with the EU mem

Får allemansrätten utnyttjas kommersiellt? Bör allemansrätten få utnyttjas kommersiellt? Det är huvudfrågorna i denna uppsats. Efter en inledande introduktion till allemansrätten, med en redogörelse för dess historiska bakgrund och nuvarande ställning i svensk rätt, presenteras vilka problem som är förknippade med kommersiell verksamhet i relation till allemansrätten. Uttrycket ”vinstproblemet” anIs commercial use of the right of public access permitted? Should it be permitted? These are the main questions in this thesis. The piece starts with an introduction to the right of public access, with an overview of its history and current legal status, and continues with a presentation of some problems associated with commercial activities in relation to the right of public access. The question

It is now established that native language affects one's perception of the world. However, it is unknown whether this effect is merely driven by conscious, language-based evaluation of the environment or whether it reflects fundamental differences in perceptual processing between individuals speaking different languages. Using brain potentials, we demonstrate that the existence in Greek of 2 color

• AimsThis research investigates how different ways of referring to anthropogenic climate change produce different sensory and affective perceptions of nature in an urban destination, and how such perceptions sustain or resist the branding strategy of such place. In doing so, it aims at showing that strategic climate communication works not only rhetorically at the level of representation, but als
