This study is a continuation of our research on understanding the possible chemical routes to the evolution of life on earth based on the “Selective Energy Transfer” (SET) theory. This theory identifies the specific vibrational mode of the catalyst that is in energy-resonance with a suitable vibrational mode of the reactant. In this way, energy is transferred from catalyst to reactant up to the en

Combined heat and power (CHP) production in combination with a district heating (DH) grid gives an energy-efficient use of wood fuels. The heat demand in the DH grid will, however, decline in the coming decades, and operators are seeking additional heat sinks. In this case study, the integration of a pyrolysis unit into an existing CHP plant was investigated as a possible solution. The retrofitted

In a world where copyright is being infringed in a plethora of ways, consumers find it difficult to access legal digital content. Therefore, this thesis investigates how copyright law governs access to legal content in the digital environment in respect of so-called consumptive use.  By apprehending a user-centric approach I evaluate whether and how copyright law accounts for the consumer interest

De första levande organismerna uppstod på jorden när den funnits i 1,5 miljarder år. Under de följande tre miljarder åren bildades livet på jorden, och existerade i harmoni, med gravitation, kosmisk-strålning, elektriska och magnetiska fält och dess cyklisk-hemlighetsfulla variationer medan exponeringen från den naturlga mikrovågstrålningen var endast i storleksordningen 210-15 W/kg. Det var i deOur team of the clinical researchers in Lund, Sweden, found that electromagnetic radiation, such as those used in mobile communications, even at shallow power values, cause users’ blood albumin to leak through the blood-brain barrier “BBB” into the brain tissue. The BBB is supposed to protect the brain against unwanted and toxic molecules potentially present in the blood, to transfer to the brain

• Misdiagnosed and maltreated scaphoid fractures filed to the Swedish National Patient Insurance Company (LÖF) 2011–2018 were analyzed in terms of complications and costs for society. All filed claims are database-registered (altogether 200 000 claims since 2000). This database was assessed in June 2019 through injury ICD10-SWE-diagnoses. Demographics, complications, complaints, corrective surgeri

OBJECTIVE: To investigate the mode of delivery and birth outcomes in relation to the duration of the passive second stage of labour in nulliparous women. METHODS AND FINDINGS: A retrospective cohort study of all nulliparous women (n = 1131) at two delivery units in Sweden. Maternal and obstetric data were obtained from electronic medical records during 2019. The passive second stage was defined as

Measurements of kinetic energies of highy charged argon ions produced by inner-shell photoionization and by ion-beam impact have been made using time-of-flight techniques. High-charge-state recoil ions produced by beams of ∼ 0.5−1 MeV/u Cl5+ are found to have energies one to two orders of magnitude higher than ions of the same charge produced by vacancy cascades following inner-shell photoionizatiMeasurements of kinetic energies of highy charged argon ions produced by inner-shell photoionization and by ion-beam impact have been made using time-of-flight techniques.

Background: Pesticide use is increasing in low- and middle-income countries (LMICs) including Costa Rica. This increase poses health risks to farm owners, farm workers, and communities living near agricultural farms. Objective: We aimed to examine the health effects associated with occupational pesticide exposure in farm owners and workers from conventional and organic smallholder farms in Costa R

Background: Etranacogene dezaparvovec, the first gene therapy approved for haemophilia B treatment, was shown to be superior to treatment with continuous prophylactic factor IX in terms of bleeding protection 18 months after gene therapy in a phase 3 trial. We report post-hoc 24-month efficacy and safety data from this trial to evaluate the longer-term effects of etranacogene dezaparvovec in indiv

Spondyloarthritis (SpA) has been associated with comorbidities, e.g., cardiovascular disease. However, little is known about the relation between SpA and chronic obstructive pulmonary disease (COPD). The aim of the study was to compare the prevalence of COPD in SpA to the general population. Patients with prevalent SpA in Skåne, Sweden, on December 31, 2018, were identified based on diagnostic cod

Background: Sexual violence is widespread in war-torn North Kivu province in the Democratic Republic of the Congo (DRC). Timely access to care is crucial for the healing and wellbeing of survivors of sexual violence, but is problematic due to a variety of barriers. Through a better understanding of care-seeking behaviours and factors influencing timely access to care, programmes can be adapted to

Industrial relevance is essential for an applied research area like software engineering. However, it is unclear how to achieve industrial relevance and how we communicate and assess it. We propose a reasoning framework to support the design, reporting, and assessment of research for industrial relevance.

To evaluate the possibility of obtaining detailed individual mobility data from archaeological teeth, the strontium isotope ratios on 28 human teeth from three separate Early-Mid Holocene, Swedish, foraging contexts (Norje Sunnansund, Skateholm and Västerbjers) were analysed through laser ablation. The teeth/individuals have previously been analysed using traditional bulk sampled thermal ionisatio

Background Exclusive breastfeeding (EBF) up to six months is sub-optimal globally. Tanzania has surpassed the World Health Assembly (WHA) target of increasing the rate of exclusive breastfeeding among children below six months to at least 50% by the year 2025 the median age of cessation of EBF is only three months. Objective To determine the time to cessation of exclusive breastfeeding and its ass

Background: Post-covid syndrome is an emerging condition involving a wide range of symptoms, including high rates of poor mental health. The diagnostic relevance and clinical severity of these symptoms are largely unknown, and evidence for treatment of post-covid mental health symptoms is lacking. This protocol describes a pilot randomized clinical trial, primarily aiming to assess feasibility, pa
