The combustion of conventional Jet A, alongside two alternative jet fuels, C1 and C5, is simulated with Large Eddy Simulations (LES) in a generic single-cup spray combustor during idle and cruise conditions. The spray is modeled using Lagrangian particle tracking and the combustion chemistry of each fuel is modeled by skeletal reaction mechanisms. The volatility and atomizability of each fuel dire

Den gemensamma jordbrukspolitiken (CAP) reformeras regelbundet och arbetet pågår nu inför nästa programperiod som börjar 2028. En betydande del av jordbruksstöden utgörs av gårdsstöd, nötkreatursstöd, kompensationsstöd, omfördelningsstöd och ersättning till naturbetesmarker. Vi analyserar hur förändringar av nivåerna på dessa stöd skulle påverka jordbrukets produktion, konkurrenskraft och miljöpåv

Lean, premixed, swirl-stabilized flames are widely used in modern Dry Low Emissions gas turbine combustors; however, the turbulent combustion process under those conditions is known to be extremely sensitive and prone to instabilities. Numerical simulations can be a valuable tool in predicting the effects of alternative fuels; however, the sensitivity of the results to different models ought to be

During epileptic seizures, neuronal network activity is hyper synchronized whereby GABAergic parvalbumin-interneurons may have a key role. Previous studies have mostly utilized 4-aminopyridine to induce epileptiform discharges in brain slices from healthy animals. However, it is not clear if the seizure-triggering ability of parvalbumin-interneurons also holds true without the use of external conv

Osteosarcoma is a malignant cancer of the bone mainly affecting adolescents. Despite progress, the clinical management of osteosarcoma is still challenging. With the current chemotherapy protocol being used for more than 30 years, the number of poor responders is increasing. Although new treatments have been explored since then, no improved tumor eradication effect have been found. In the present

This study aimed to investigate self-reported physical activity levels, perceived body appearance, and body functioning in relation to perceived wellbeing among adolescents. A cross-sectional survey was performed in four upper secondary schools in one municipality in southern Sweden. Data were obtained from questionnaires completed by 1,491 adolescents (55.4% females; median age 16; range 15–17 ye

Introduction The purpose of this systematic review and meta-analysis was to evaluate the effects of exercise on (i) the prevention of cancer-related lymphedema (CRL) and (ii) the treatment of CRL, lymphedema-associated symptoms, and other health outcomes among individuals with CRL. Methods An electronic search was undertaken for exercise studies measuring lymphedema and involving individuals at ri

This paper investigates how multilingual speakers may recognize compounds, focusing on the theory that a multilingual recognizes a compound equivalent of a compound faster than a monomorphemic equivalent of a compound. To test this, I administered a translation recognition task to native speakers of Swedish who spoke English as their first L2. The informants were shown the pairs in sequence and ei

Low tax revenues in many African countries are hindering sustained economic development and aid could have an inhibiting effect on the development of fiscal capacity. This paper will use newly published high-quality data on tax revenues to dive deeper into the effects of aid on hard-to-collect taxes in Africa between 1960-2015. Previous aid literature has mostly focused on short-term effects on re

The most well researched associative memory illusion (AMI) is the Deese–Roediger–McDermott (DRM) paradigm: a list learning task found to induce false memories though study lists with associated words. Typically, the study lists are composed of the 12—15 most frequent Kent-Rosanoff word-pair associations of a "critical lure". This thesis attempts a different approach to list generation.

The compositions of alternative jet fuels can vary radically, and the consequences of these differences are a subject of ongoing investigation. Numerical combustion simulations are vital to this research and require chemical reaction mechanisms that efficiently and accurately capture the chemical pathways of combustion. Here, we present the recently developed Z79 collection of small pathway-centri

This study looks at the investment decision-making process of institutional Venture Capitalists. Prior research has shown that general criteria for the valuation of new ventures have not significantly changed over time. Studies looking at the stage-specific criteria however consider different factors important. Using the verbal protocol method in the screening phase with two venture capitalists, w

Forum för ofrivilligt celibata män, incels, har fått mycket uppmärksamhet från den samhällsvetenskapliga forskningen på grund av dess våldsbejakande och hatiska natur. Detta fokus ifrågasätts i denna studie då det bidrar till att fenomenet ofrivilligt celibata ofta ses som en manlig företeelse, vilket osynliggör ofrivilligt celibata kvinnors, femcels, uteslutning ur romantik i dagens samhälle. I d

Ribbed channel flows play a crucial role in various engineering systems where turbulence enhancement and improved heat transfer are required, such as in turbine blade cooling and combustor wall applications. Numerical simulations have emerged as an essential tool for analyzing the intricate turbulence dynamics and flow separation phenomena, which are fundamental for optimizing the channel performa

Efter kandidatexamen i Service Management sökte Emmy sig vidare till masterprogrammet i Sustainable Service Management. Idag studerar hon med fokus på hållbarhet, strategiskt tänkande och tjänsteutveckling, och ser en framtid där hon kan hjälpa organisationer att navigera mot hållbara verksamheter.
