Optically pure lactic acid (LA) is needed in PLA (poly-lactic acid) production to build a crystalline structure with a higher melting point of the biopolymer than that of the racemic mixture. Lignocellulosic biomass can be used as raw material for LA production, in a non-food biorefinery concept. In the present study, genetically engineered P. acidilactici ZP26 was cultivated in a simultaneous sac
Through a systematic review and a series of meta-analyses, we evaluated the general responsiveness of putative transcriptional biomarkers of general toxicity and chemical stress. We targeted metal exposures performed on bivalves under controlled laboratory conditions, and selected six transcripts associated with general toxicity for evaluation: catalase (cat), glutathione-S-transferase (gst), heat
Ischemic heart disease is the leading cause of death in high-income parts of the world and is caused mainly by atherosclerosis in the coronary arteries. The rupture of an atherosclerotic plaque with subsequent platelet activation and clot formation can lead to myocardial infarction (MI). Atherosclerosis is a complex process, which involves the accumulation and oxidation of low-density lipoprotein
Popular Abstract in Swedish Neuroblastom är den vanligaste solida tumören, utanför hjärnan, hos små barn och finns nästan inte alls hos vuxna. Varje år insjuknar mellan femton och tjugo barn i Sverige, de flesta före två års ålder. Överlevnaden har ökat de senaste tjugo åren men är fortfarande på låga nivåer för de mer aggressiva formerna. Neuroblastom uppstår i det sympatiska nervsystemet. DärförIn this thesis, the main focus has been on the childhood cancer neuroblastoma, one of the most common and lethal childhood tumours. Neuroblastoma has througout the years continued to be a clinical and biological enigma. Our first focus was on one of the most important biological risk factors in neuroblastoma -- amplification of the oncogene MYCN in the tumour cells. Because amplified MYCN typical
This study describes a new method for the fixation of titanium hip stem prostheses based on interdigitation of irregularly shaped porous titanium granules onto bone tissue. The granules were distributed into the prepared femoral cavity using a vibrating tool, and the stem was vibrated and tapped into the bed of granules. In this pilot study, 5 patients were followed between 9 and 15 years. The cli
To link aesthetics to traffic safety, the field of environmental psychology was consid-ered. A new model of driving behaviour was developed, based on Lewin’s (1951) equation, B = f (P,E) and by employing Küllers’ (1991) model of the basic emotional process. The employed model B = f (R(Road), U(Users), A(Task), P(Person)), states that driving behaviour (B) is related to the physical environment (R)
Popular Abstract in Swedish Under den geologiska period som kallas kvartärtiden (de senaste 2,6 miljoner åren) har flera istider (glacialer) och mellanistider (interglacialer) avlöst varandra enligt ett mönster där glacialerna varar i ungefär 100000 år och mellanistiderna i ca 10000 år. Under istiderna täcktes stora landområden på norra halvklotet, bl.a. Skandinavien, av väldiga inlandsisar. Då deThe aim of this thesis was to reconstruct the Holocene vegetational and climatic development in the Sylarna-Storulvån area, western Jämtland, in the central Scandes Mountains. Temporal trends and fluctuations in the elevation and vegetational character of the tree-limit ecotone were studied mainly by means of pollen and plant macrofossil analysis of two lake sediment sequences (Lakes Stentjärn and
Hur mycket information bör noterade bolag offentliggöra? Det är en fråga som har diskuterats tidigare, men som har blivit aktuell på nytt med noteringsaktens (förordning (EU) 2024/2809) ikraftträdande i december 2024. Den här uppsatsen riktar in sig på noteringsaktens regeländringar avseende kraven på offentliggörande av insiderinformation, med särskilt fokus på utvidgade undantag för offentliggörHow much information should be disclosed by listed companies? This is a question that has been discussed previously, but which has become relevant again with the entry into force of the Listing Act (Regulation (EU) 2024/2809) in December 2024. This thesis focuses on the regulatory changes introduced by the Listing Act regarding the requirements for disclosure of inside information, with particular
Marine debris is a major threat to wildlife and human health. This study examines the socioeconomic vulnerability of informal housing as arguably one of the main drivers of the abundance of marine debris in the aftermath of a tropical cyclone. Using the Abaco Islands, Bahamas, as a case, the study applies the capabilities approach to assess the societal impact of Hurricane Dorian. Findings indicat
Crowdfunding is often considered as a financial source to close the early stage financial gap of new ventures. However, there is little research on its impact regarding other liabilities new ventures face. The aim of this study is to find evidence on how crowdfunding can provide new ventures with additional value apart from financial resources. For this purpose, the concept of liability of newness
The Milky Way harbors a supermassive black hole (SMBH) at its dynamical center. Surrounding the SMBH is a dense nuclear star cluster (NSC) which is believed to include a binary population. Beyond $0.1\mathrm{pc}$ from the SMBH, Eccentric-Kozoai Lidov oscillations are suppressed by general relativity precession, and the dynamical evolution of binaries are completely dominated by encounters with oth

The handover (HO) procedure is one of the most critical functions in a cellular network driven by measurements of the user channel of the serving and neighboring cells. The success rate of the entire HO procedure is significantly affected by the preparation stage. As massive Multiple-Input Multiple-Output (MIMO) systems with large antenna arrays allow resolving finer details of channel behavior, w
Human-induced impacts are increasing pressure on coastal ecosystems, particularly on benthic ecosystems in high-latitude regions. It has become evident that three of the greatest marine environmental challenges related to anthropogenic activity are warming, ocean acidification, and deoxygenation. The effect of these environmental changes on our uncertain future has created a need to understand the
The increasing threat of soil degradation presents significant challenges to soil health, especially within agroecosystems that are vital for food security, climate regulation, and economic stability. This growing concern arises from intricate interactions between land use practices and climatic conditions, which, if not addressed, could jeopardize sustainable development and environmental resilie
Background:Preparing for the end of life is believed to help mitigate emotional suffering for both patients and their caregivers. However, empirical evidence on the emotional benefits of feeling prepared for death remains limited.Aim:This study uses data from the international iLIVE project to examine how perceived end-of-life preparedness is associated with emotional suffering among patients and
What are the main challenges for fossil-free agriculture and food systems, according to Swedish farmers? And what do farmers think fossil-free farms should look like, and how should they function? What actions are needed from different actors to achieve these visions by 2050? These questions were discussed during a lunch-to-lunch workshop in Eskilstuna, 13-14 November 2025. The purpose of the work
