Trimethylolpropane (TMP) is an important industrial chemical used to produce various value-added chemicals and polymers. In this study, both biobased butyraldehyde and formaldehyde were produced by the incomplete oxidation of bio-1-butanol and biomethanol, respectively, and were then used to produce a biobased TMP. High selective incomplete oxidation of primary alcohol to aldehyde is a challenging
This article investigates trapping mechanisms in AlGaN/GaN high electron mobility transistors (HEMTs) at cryogenic temperatures (CTs) down to 4.2 K, using pulsed I–V and drain current transient spectroscopy (DCTS) measurements. The results revealed an overall increase of trapping effects at CT. In particular, a substantial increase in current collapse at low temperatures was observed and predomina
BACKGROUND: Sharp force injuries display varying patterns depending on the manner of death (homicide, suicide, accidental). The purpose of this study was to analyse forensic autopsy data to examine the characteristics of sharp force injuries on the extremities, to differentiate between different manners of death and to examine demographic differences.METHODS: This retrospective cohort study utiliz
High-grade serous ovarian cancer (HGSOC) is the most prevalent and aggressive subtype of ovarian cancer. The combination of late-stage diagnosis and the tendency to exhibit resistance to existing treatments highlights a critical gap in effective therapeutic options. There is thus a need for novel strategies for targeting HGSOC, particularly in its advanced stages. To address this gap, we developed
An experimental study of smoke propagation from an apartment to an escape route corridor in a real-scale residential building is presented in this paper. The experiments were performed using the same experimental setup but with different ventilation and apartment door opening times. The setup consisted of a fire in a two-seater sofa in an apartment connected to a corridor and other apartments. A t
We aimed to determine if thyroid autoimmunity is associated with a child's risk for subsequent development of islet or celiac autoantibodies. Children at high genetic risk of type 1 diabetes were followed for thyroid autoimmunity (thyroid peroxidase antibodies [TPOAb] and thyroglobulin antibodies [TGAb]), islet autoimmunity (IA), and celiac disease autoimmunity [CDA] in The Environmental Determina
Risk factors for developing bloodstream infections (BSIs) caused by Aerococcus bacteria remain insufficiently examined. In this nationwide case–control study in Sweden, 19 of 23 clinical microbiological laboratories identified patients who had aerococcal BSIs during 2012–2016. We compared each of those index patients with 4 controls matched for age, sex, and county of residence. Overall, 588 episo
Introduction. There is no water-tight division between different categories of human rights. In particular, it is important to note that although the project of transforming the 1948 Universal Declaration of Human Rights into treaty form culminated in separate Covenants including, on the one hand, civil and political Rights and, on the other hand, economic, social and cultural Rights, it did not r
General issues Basic features The International Covenant on Civil and Political Rights (ICCPR) was adopted by the United Nations General Assembly in 1966, and, after the required number of ratifications, it entered into force on 23 March 1976. To a large extent the Covenant, together with the simultaneously adopted International Covenant on Economic, Social and Cultural Rights, codifies in the for
Musculoskeletal disorders are a significant public health burden concern, projected to increase in the coming decades, and will substantially contribute to the rising prevalence of functional impairment, frailty and disability in a growing global population. Since persons with musculoskeletal disorders tend to have immune dysfunction, inflammation or be taking immunosuppressive medication, prevent
Proenkephalin (PENK) is assumed to be freely filtered by the glomerulus, thus potentially useful for estimating glomerular filtration rate (eGFR). Recently developed eGFR-equation based on PENK and creatinine has not been validated against existing cystatin C-based equations. This study aimed to test the hypothesis of free filtration of PENK. Also, the PENK-creatinine based eGFR-equation was valid
Dance as an art form is strongly connected to the experience of movement. Dance is also connected to the experience that occur in the relation between the audience and the performers on stage. Therefore, information is based on subjective impressions. It’s something limited and framed in a certain time and space that arises, lives and dissolves in the body and in the now. To add the archival funct
Author: Ebba Eiroff Title: Students narratives of loneliness Supervisor: Kristina Göransson Assessor: Mats Hilte The aim for this qualitative study was to examine university students experiences of loneliness based on Erving Goffman’s dramaturgy theory, together with the conceptions of normality, shame and guilt. How students describe feelings of loneliness and how they relate their experiences t
The preferred method for synthesising therapeutic peptides today is by Solid-Phase Peptide Synthesis (SPPS). SPPS is a wasteful process, where the main component of the waste is hazardous solvents, i.e., N,N-dimethylformamide (DMF), N-methylpyrrolidone (NMP) or dichloromethane (DCM). 3 It is therefore desirable to search for new and greener solvents to use for SPPS, which is what has been studied
This qualitative study applies to young men between the ages of 18 and 21 who live in community homes (HVB hem), and have an ongoing substance abuse and addiction problem. The focus will be on the motivation and treatment that from the young men's perspective promotes the process of change to start a life without addiction. This activity, which fulfills an incredibly essential function in soci
