Biodegradation of Polylactic Acid: Enzymatic and physicochemical approach along with ecotoxicological assessment in Daphnia magna

Plastföroreningar är ett av dagens största miljöproblem. Även om många biologiskt nedbrytbara plaster har utvecklats för att minska denna påverkan, bryts de inte alltid ned effektivt i verkliga miljöer. En av de mest använda biologiskt nedbrytbara plasterna är PLA (polylaktid), som ofta förekommer i förpackningar, 3D-utskrifter och engångsartiklar. Trots att PLA är märkt som biologiskt nedbrytbartIntroduction: Biodegradable plastics such as polylactic acid (PLA) are increasingly used as sustainable alternatives to conventional plastics, yet their degradation in natural environments remains inefficient. Background: Although enzymes such as cutinases can hydrolyse ester bonds in PLA, their behaviour in the presence of PLA nanoparticles and potential inhibitory effects are not well understood

A Theory of Leadership Meta-Talk and the Talking-Doing Gap

We identify managers' meta-level talk about the positive purpose, meaning, and significance of their actions as an overlooked type of leadership behaviour and call it leadership meta-talk. We outline why leadership meta-talk is not necessarily truthful or deceptive, but selective and loosely coupled with leadership practice. We discuss varieties of leadership meta-talk, namely aspirational, sub-te

Verbal memory in major depressive disorder in a long-term perspective : a five-year longitudinal study of first episode patients

Introduction: Major depressive disorder (MDD) is associated with cognitive impairment, including verbal memory. Limited knowledge exists following memory performance in first episode (FE) MDD. This study investigated verbal memory, depressive symptoms, and relapse in FE MDD over five years, from the trait, state, and scar perspectives. These perspectives suggests that deficits in memory either pre

Prevalence of Hidradenitis Suppurativa in Lund and Gothenburg, Sweden : An Analysis from the Global Hidradenitis Suppurativa Atlas Initiative

Methods: This study was a part of the Global Hidradenitis Suppurativa Atlas (GHiSA) initiative. The study was multicentered and included apparently healthy adults accompanying a patient to the Department

Stäpporangelav Caloplaca raesaenenii funnen vid Åhus – en förbisedd eller naturligt sällsynt art i Sverige?

Orangelaven Caloplaca raesaenenii hade bara samlats och artbestämts vid ett tidigare tillfälle i Sverige innan den uppmärksammades häromåret i ett sandmarksreservat vid Åhus i nordöstra Skåne. I denna artikel beskrivs förekomsten på den aktuella lokalen. Dessutom sammanfattas utbredning, ekologi och substratval utomlands, och möjligheten att hitta den på fler ställen i landet samt hot mot de aktue

Assessment of Wind Energy Potential in Ethiopia : A Case Study of the Sela Dingay Wind Farm

Wind energy is an increasingly viable solution for sustainable power generation, particularly in developing regions with high wind potential. This paper presents a comprehensive analysis of the wind power and energy output estimation for the Sela Dingay wind farm, a candidate site in Ethiopia. The study utilizes measured wind speed data at 50 meters and interpolates it to different hub heights (91

Critical Management Studies : From One-Dimensional Critique to Three-Dimensional Scepticism

Critical Management Studies (CMS) has largely relied on one-dimensional critique which focus on the negation of a dominant social order. This strong focus has made the field increasingly stale and preoccupied with standard objects for critique. This paper suggests that if CMS is to move beyond these problems, it needs to develop three-dimensional thinking, including understanding, questioning, and

Evaluation of a modified version of the attitudes about mental illness and its treatment instrument : psychometric assessment and attitudes among adolescents in Sweden

Introduction: Globally, many adolescents suffer from mental health problems and related stigma. Assessing mental health stigma among youth is crucial to addressing this problem. The aim of this study was to examine the psychometric properties of a modified version of the Attitudes About Mental Illness and its Treatment (AAMIT) instrument and to describe attitudes according to the instrument, among

THE QUEST FOR TRUST IN DECENTRALISED FINANCE : SCREENING OWNERSHIP IN HIGH TECH START-UPS

Building on the role of trust in finance and screening theory, our research explores the correlation between founders occupying leadership positions such as CEO, CTO, or CFO and the funds raised through Initial Coin Offerings (ICOs). We analyse data from 2,047 ICOs between 2017 and 2021 and reveal that founders occupying positions of authority within their organisations are perceived by investors

Longitudinal decline in upper-limb range of motion in adults with cerebral palsy

To analyse longitudinal changes in passive range of motion (ROM) in the upper limb in adults with cerebral palsy (CP). Method: Passive ROM for shoulder abduction and flexion, supination, and elbow and wrist extension was analysed in a longitudinal cohort of adults aged 16 to 76 years from the Swedish CP registry. Individual ROM trajectories and mean ROM curves were calculated using the Manual Abil

Prevalence of atrial fibrillation among Swedish adults participating in the general population study EpiHealth

Objectives. This study aimed to estimate the prevalence of atrial fibrillation (AF) and identify its associated comorbidities in adults aged 45 years and older, using data from the Swedish general population study EpiHealth. Design. In a cross-sectional design, data of health history, lifestyle factors, anthropometric measurement, and 1-lead ECG recordings from participants in the EpiHealth study

Innovative radiotherapy approaches

Radiotherapy (RT) with concurrent chemotherapy is the standard of care for squamous-cell carcinoma of the anal canal (SCCAC), achieving favorable results in terms of local control and overall survival. However, locoregional failure remains common despite advances such as intensity-modulated radiotherapy (IMRT), which reduces toxicity but has limitations. Despite the benefits of IMRT, frequent and

Floating charges in the Nordic countries

This chapter analyses floating charges in the Nordic countries, focusing on Denmark, Norway, Sweden and Finland. Nordic property laws are known for their functional approach, and while property law rules in the Nordic countries are generally fragmentary, Nordic security rights laws are more codified. The four Nordic countries all have floating charges (or equivalent security rights). The chapter d

Tending to the Particular : Navigating Tensions Around Principles of Alternativity Through an Ethics of Care

Alternative organizations must continuously address conflicts that emerge regarding diverging prioritizations and interpretations of autonomy, solidarity, and responsibility. We explore how tensions around alternative moral principles can be navigated through relational processes that attune to others' needs, emotions, and concerns. Building on an organizational ethnography of a cooperative campai

A Prospective Study of Immune Response After COVID-19 or Vaccination and Correlation Between Avidity Index and Neutralizing Capacity

Background: Serological response is an important aspect of COVID-19, especially for evaluation of vaccine effect and risk of severe infection. The gold standard to assess this is analysis of neutralization capacity, but such assays are not widely available, with antibody levels often used as an approximation of the neutralizing ability. Avidity index is a measure of antibody function and avidity m
