Loss and damage in fisheries : Building on fishers’ situated knowledge to inform ways of knowing

Loss and damage in fisheries is acknowledged in climate change policy and science but is both undefined and contested, and there is a lack of empirical exploration of the topic. This paper presents the first in-depth, empirical analysis of how fishers’ situated knowledge of socio-ecological changes can inform our understanding of loss and damage in fisheries. The paper conducts a case study from M

Structural characterization of an extracellular contractile injection system from Photorhabdus luminescens in extended and contracted states

Contractile injection systems (CISs) are phage tail-like nanosyringes that mediate bacterial interactions by puncturing target cell membranes. Within these systems, Photorhabdus Virulence Cassettes (PVCs) can translocate toxins across eukaryotic target cell membranes and have been engineered to deliver diverse protein cargoes into non-natively-targeted organisms. Despite the structural insights in

Den revolterande eliten eller den kreativa klassen? : Christopher Lasch, Richard Florida och det amerikanska presidentvalet 2024

Aims The Trump movement displays several key features of a populist movement with a strong leader and a broad unorganized base of followers opposed to a per-ceived liberal elite establishment. In 2024, Trump gained strong support from strata with low income, low education and Hispanic men, previously not strong support-ers of Republicans. This study investigates the preconditions for a populist moAims The Trump movement displays several key features of a populist movement with a strong leader and a broad unorganized base of followers opposed to a per-ceived liberal elite establishment.

Distribution of mental health diagnoses in relation to sexual orientation and gender discontent in a late adolescent community population

BACKGROUND: Few population studies have assessed the prevalence of various psychiatric disorders separately for sexual and gender minority groups, and none in an adolescent population. Given the increased mental health problems in sexual and gender minority groups combined, the present study aimed to estimate prevalence of mental disorders in separate sexual minority groups as well as gender disco

Rationale and design of a registry-based randomized controlled study of personalized biomarker-based risk score-guided stroke prevention treatment in atrial fibrillation

Background: Stroke and reduced survival are devastating complications of atrial fibrillation (AF). Biomarker-based ABC-AF risk scores improve risk prediction in AF, and risk-guided treatment recommendations may improve patient outcomes. Design: The ABC-AF study is a national, multicenter, prospective, registry-based, randomized controlled, parallel-group, open-label study. Its primary objective is

Prevalence of Sexual and Gender Minorities in a Swedish Adolescent Community Population : Stability vs. Fluidity of Sexual Orientation

This study examined the prevalence, stability, and fluidity of sexual orientation as well as the prevalence of gender discontent. From a community sample (i.e., all adolescents of the age cohort were invited), this study analyzed data from 1513 adolescents (50.5% females), who replied to questions about sexual attraction on at least one of three occasions (age 14: n = 623; age 15: n = 1322; and ag

Understanding the role of obesity in endocrine therapy for postmenopausal breast cancer : significance of the BIG 1–98 and ATAC trial data

Obesity is a known risk factor for poor breast cancer outcomes, but its impact on endocrine therapy efficacy remains unclear. While the ATAC trial suggests reduced effectiveness of aromatase inhibitors (AIs) in women with obesity, the BIG 1–98 trial found no significant differences. Clinical and biological evidence indicates that obesity may impair AI efficacy by increasing aromatase activity and

Engineering bimetallic CuAu to suppress hydrogen evolution and enhance charge transfer for improved photoelectrochemical nitrogen reduction

Green ammonia synthesis from nitrogen via photocatalysis and electrocatalysis has emerged as a pivotal research focus in sustainable chemical processes. The efficient catalytic reduction of nitrogen necessitates concurrent nitrogen activation and hydrogen evolution suppression, representing a significant challenge. In this study, CuAu bimetallic-modified TiO2 catalysts were developed and engineere

Transplacental sirolimus : a new treatment strategy for life-threatening fetal cardiac rhabdomyomas—a case report

Large cardiac rhabdomyomas can disturb hemodynamic flow. Tuberous sclerosis complex is the most common cause of cardiac rhabdomyoma in fetuses. Recently, a mammalian target of rapamycin (mTOR) inhibitor effectively treated rhabdomyomas associated with tuberous sclerosis. Here, we report the effectiveness of an mTOR inhibitor in treating a fetus with large rhabdomyomas exhibiting severe heart failu

Distorted octahedral sites drive early formation and stabilisation of nickel oxyhydroxides in trimetallic nickel–iron–molybdenum oxides

Trimetallic nickel–iron–molybdenum oxides are excellent electrocatalysts for alkaline water electrolysis despite experiencing severe molybdenum dissolution. While the impact of molybdenum on fresh samples is well-understood, its substantial loss during operation without compromising performance presents a unique puzzle. Here, we show that the initial presence of molybdenum induces the formation of

Optimal conjunctive use of surface water and groundwater resources : a systematic state-of-the-art review with potential application in arid and semi-arid regions

We reviewed papers on optimal conjunctive use of surface and groundwater (GW) with application in dry regions. Selected papers from the last 25-year period were reviewed using the PRISMA method. We show that with increasing scarcity of water, objectives of models developed for optimal conjunctive use have become more environmentally and socially oriented. About two-thirds of the studies are dedica

Ethnic and religious differences in female labor force participation : evidence from Syrian census data

This paper investigates the magnitude and drivers of ethnic and religious disparities in Female Labor Force Participation (FLFP) in Syria. Using census data and the Gelbach decomposition method, the analysis reveals substantial FLFP gaps across groups, reaching up to 18 percentage points. To understand the factors underlying these gaps, the analysis exploits the heterogeneity in economic developme

To promote a better understanding of this disabling condition and to foster research

Konsumtion i kristider - effekter av stigande livsmedelspriser

Under 2022 och 2023 ökade livsmedelspriserna kraftigt. Även energipriserna steg kraftigt under 2022. För att motverka den stigande inflationen höjde Riksbanken styrräntan. Sammantaget medförde det betydande kostnadsökningar för de svenska hushållen. I detta projekt har vi studerat hur prisökningarna har påverkat livsmedelsförsäljningen inom detaljhandeln och kostintaget på befolkningsnivå. Analyse

Myeloperoxidase expressing tumor associated neutrophils are associated with worse prognosis in metastatic breast cancer patients

Tumor associated neutrophils (TANs) exert dual and opposing functions in tumors, acting pro-tumorigenic and anti-tumorigenic, depending on tumor progression, polarization state and subtype. Consequently, the prognostic impact of TANs in breast cancer is also contradictory. Since neutrophils are critically needed to fight infections in cancer patients, the mediators leading to tumor progression nee

Oxy-ethane combustion : Measurements of the laminar burning velocities and kinetic insights into CO2 effects

Oxy-fuel combustion is regarded as an underpinning technology for carbon capture and utilization. Ethane (C2H6) is the primary non-methane component in natural gas and a fundamental C2 fuel. In this work, laminar burning velocities (LBV) of C2H6/O2/CO2 mixtures were measured using the heat flux method at atmospheric pressure, spanning initial temperatures of 308–348 K, equivalence ratios of 0.6–1.
