Levulinic acid (LA) is considered to be one of the promising organic bio-platform chemicals and intermediates for the synthesis of fuels, chemicals, and polymers. In the present study, heterogeneous catalytic dehydration of hexose sugars, fructose and glucose, using a strong cation exchange resin (hydrogen form) as an acid catalyst, was performed to produce LA in an aqueous medium. The effect of s
In this study pause patterns during writing were investigated and compared in a developmental perspective. The material consisted of keystroke logging recordings of the writing process of 30 expository texts written by 30 persons from the age groups 13-year-olds, 15-year-olds and 17-year-olds. A total number of 3080, all pauses longer than two seconds, were identified and categorized, according to
This licentiate thesis in industrial design concerns the challenge and opportunity to meet the demographic changes and the future senior market. The aim is to explore how various user-centered design methods can be combined, modified and practiced to create conditions for the design of totally new or improved products. Design is understood as a process to develop solutions with the starting point
The evolutionary relationship between signals and animal senses has broad significance, with potential consequences for speciation, and for the efficacy and honesty of biological communication. Here we outline current understanding of the diversity of colour vision in two contrasting groups: the phylogenetically conservative birds, and the more variable butterflies. Evidence for coevolution of col
Många beteenden hos djur kan vara oflexibla och mer eller mindre ”hard-wired” i hjärnan. Sådana beteenden kan vara ändamålsenliga för regelbundna och rytmiska förändringar i naturen, såsom dag och natt, årstider, etc. Men många faktorer är naturligtvis oförutsägbara i naturen. För sådana oförutsägbara förändringar är det bättre för djur att vara flexibla i sitt beteende. Kognition är en process soThe Paridae (tits, titmice and chickadees) is a bird family consisting of both food hoarding and non-hoarding species. Many studies have been conducted on birds that are considered to be cognitively advanced, such as parrots and corvids, whereas much less is known about these small passerines. In this thesis, I have investigated the cognitive abilities of two members of the Paridae family; marsh t
Purpose: Many centers aim to plan liver transarterial radioembolization (TARE) with dosimetry, even without CT-based attenuation correction (AC), or with unoptimized scatter correction (SC) methods. This work investigates the impact of presence vs absence of such corrections, and limited spatial resolution, on 3D dosimetry for TARE. Methods: Three voxelized phantoms were derived from CT images of
OBJECTIVE:: To assess the prognostic value of continuous amplitude-integrated electroencephalogram in comatose survivors after cardiac arrest and treated with hypothermia. DESIGN:: Prospective observational study. SETTING:: General intensive care unit at a university hospital. PATIENTS:: Comatose patients after cardiac arrest and treated with hypothermia. INTERVENTIONS:: Patients were sedated and
Peatlands store large amounts of carbon in terrestrial ecosystems and they are vulnerable to recent warming. The ongoing warming may change their carbon sink capacity and could reduce their potential to sequester carbon. In this study, we simulated peatland carbon dynamics in distinct future climate conditions using the peatland-vegetation model (LPJ-GUESS). The study examined whether less pronoun
In an ethyl methanesulfonate oat (Avena sativa) mutant population we have found a mutant with striking differences to the wild-type (WT) cv. Belinda. We phenotyped the mutant and compared it to the WT. The mutant was crossed to the WT and mapping-by-sequencing was performed on a pool of F2 individuals sharing the mutant phenotype, and variants were called. The impacts of the variants on genes
Informed by queer life practices, theories, and affinities, this documented artistic research project (doctoral thesis) draws from new materialist and post-humanist discourse in order to reconsider what role visual media play in the historical need to separate the human and the environmental. It asks, how do we challenge prevailing perceptions of film and photography as inexorably linked to ideas
We report the discovery of a hot (Teq ≈ 1055 K) planet in the small-planet radius valley that transits the Sun-like star TOI-733. It was discovered as part of the KESPRINT follow-up program of TESS planets carried out with the HARPS spectrograph. TESS photometry from sectors 9 and 36 yields an orbital period of {equation presented} days and a radius of {equation presented}. Multi-dimensional Gauss
Hydropower is one of the renewable energy sources having the highest conversion efficiency than other renewable energy sources. The hydro turbine is considered as the main component of a hydropower plant and operation and maintenance of various components are the critical issues for optimal energy generation. Under the present paper, a comprehensive literature review on the operation and maintenan
Våld i nära relationer har länge varit ett stort samhällsproblem. Problematiken utgörs framförallt av systematiskt våld från en närstående, ibland även med dödlig utgång. Våldet förekommer ofta i hemmet och forskning har visat att kvinnor drabbas i större utsträckningen av grövre våld i jämförelse med män. Vid närmare samtal om ämnet har man funnit ytterligare en särskilt utsatt grupp som ofta falDomestic violence has long been a major societal issue. Domestic violence usually consists of systematic violence from a close relative, sometimes even with a fatal outcome. Research has shown that women are affected to a greater extent by more serious violence in comparison to men. During closer discussions on the subject another particularly vulnerable group has been found to often fall between
I december 2019 hittade polisen en termosbomb i ett underjordiskt garage i Malmö. En av personerna som misstänktes för brottet hade tidigare dömts för liknande typer av brottslighet och hade en koppling till Hells Angels. Hans DNA hade även återfunnits på locket till den termos som sprängladdningen var placerad i. Tingsrätten använde hans tidigare brottslighet och bakgrund som bevis för hans skuldIn December 2019, the police discovered a thermos bomb in an underground garage in Malmö. One of the suspects had previously been convicted of crimes similar to this and had connections to the Hells Angels motorcycle club. His DNA also matched DNA found on the cap of the thermos containing the explosive charge. The district court used his criminal record and affiliation with Hells Angels as eviden
Uppsatsen behandlar frågan kring huruvida EU:s sanktionsförfarande mot personer och enheter i syfte att bekämpa terrorism är förenligt med grundläggande rättssäkerhetskrav med fokus på förutsebarhetskravet och processuella rättigheter. Internationella sanktioner är ett instrument för att skapa fred och säkerhet samt främja demokrati och mänskliga rättigheter. Användningen av sanktionsåtgärder har This thesis addresses the question of whether EU sanctions against certain persons and entities to combat terrorism are compatible with fundamental principles of legal certainty, concentrating on predictability and procedural rights. International sanctions are coercive political and legal measures imposed to ensure peace and stability and promote democracy and human rights. The use of sanctions h
Ersättningen till ledande befattningshavare identifierades i slutet av förra millenniet som en bidragande faktor till det låga förtroendet för näringslivet i USA och i Sverige. Lagstiftarna har sedan dess försökt komma till rätta med problemen både genom lagreglering samt via bolagskoder och listningsregler på börser. Det jag fokuserat på är vem som har makten i beslutsfattandet och hur intressen Executive officers and director remuneration was identified as a contributory factor for the low confidence-ratings in trade and industry in the beginning of this millennia. The legislator in both Sweden and in the US has since dealt with the problems by enacting laws as well as regulating through corporate governance codes and stock listing manuals. I have focused on locus of power over executive
Syftet med arbetet har varit att, med hjälp av bayesiansk sannolikhetsteori som bevisvärderingsmetod, kritiskt analysera svenska människohandelsmål. Detta har gjorts för att utröna om det förekommer tecken på bristande bevisvärdering från domstolarna som bidrar till att rekvisit ej anses styrkta i dessa mål där någon blir friad, och i utsträckning bidragit till bevisproblematik kring brottet. SyftThe purpose of this paper has been to critically analyze Swedish court cases of human trafficking where the accused has been acquitted of such a criminal act. The critical analysis has been executed with the aid of Bayesian probability theory as an evidence evaluation method. This has been done to determine whether there are signs of flawed evidence evaluation from the court itself which has contr
Nämndemän, även kallade lekmannadomare, har en lång tradition i Sverige och har en viktig roll när det gäller att representera folket och upprätthålla principen om att man ska dömas av sina likar. Idag har lekmannadomarna individuella röster vilka väger lika tungt som juristdomarens röst. Lekmännen nomineras av politiska partier och vid tillsättning av nämndemannakåren ska en allsidig sammansättniSweden has a longstanding tradition of incorporating lay judges into the judi-cial process. Today, lay judges have individual votes in Swedish courts and play a crucial role in upholding the principle of being judged by one´s peers. Swedish lay judges are nominated by political parties and appointed by the municipal council. When appointing lay judges, effort should be made to en-sure a diverse co
