Accurate global estimates of accumulation-mode particle number concentrations (N100) are essential for understanding aerosol–cloud interactions and their climate effects and for improving Earth system models. However, traditional methods relying on sparse in situ measurements lack comprehensive coverage, and indirect satellite retrievals have limited sensitivity in the relevant size range. To over

Quantitative investigation of insect activity in their natural habitat is a challenging task for entomologist. It is difficult to address questions such as flight direction, predation strength and overall activities using the current techniques such as traps and sweep nets. A multi-spectral kHz remote detection system using sunlight as an illumination source is presented. We explore possibilities

Boreal forests are globally important carbon (C) sinks, but strategies for maximising their climate benefit remain under debate. Major uncertainties in this discussion arise from contrasting sink-source estimates, which largely emanate from inherent limitations of standard measurement techniques to distinct spatio-temporal scales. Here, we use a spatially-nested measurement framework that integrat

Current advancements in molecular techniques for identifying multiple species from bulked soil samples have expanded our capacity for large-scale soil biodiversity assessments. However, these methods often lack validation and contextualization. Recent cross-European studies based on environmental DNA (eDNA) have reported unexpectedly high biodiversity in intensively managed agricultural soils comp

This ESMO CPG provides key recommendations and algorithms for managing DLBCL, FL, HL, MCL, MZL, PCNSL and PTCL. •It covers epidemiology, diagnosis, staging, risk assessment, treatment of primary and refractory disease and follow-up. •Treatment algorithms for each lymphoma type are provided. •The author group encompasses a multidisciplinary group of experts from different institutions and countries

We recently published an article that demonstrates how eDNA can reveal shifts in the annual timing of wind-carried dispersal agents (spores) of mosses and liverworts.

A secondary objective of Bryomolecules is to apply methods developed in the project for what is known as ex situ preservation, that is, maintaining collections of endangered species in laboratory cultures. It is undoubtedly always best to preserve the species in their natural environment, but sometimes this is not enough. Lab cultures could potentially be used to replace populations that have gone

The scene floor of the forest theatre consists of a green mat of small plants. For most people it is quite anonymous and un-noticed, but several hundreds of species could thrive in this environment. In my research, I try to understand aspects of this hidden world of mosses and liverworts, including their relations to other plants and animals.

The events of September 8, 1978, in Iran, commonly known as ‘Black Friday’, have long been portrayed as a mass killing of peaceful protesters by the Shah’s regime, with widely cited death tolls ranging from several hundred to several thousand. However, this article presents a comprehensive reassessment of the incident at Jaleh Square in Tehran, arguing that the dominant narrative is rooted more in

Objectives To investigate sex education in Swedish schools regarding content, satisfaction, and suggested improvements, as described by teenagers and young adults. Methods Waiting-room survey conducted among 225 female patients (aged 13-25) at youth and student health clinics in one large-, and one medium-sized Swedish city. Results Most participants (97%, n=218) had received sex education in scho

Objectives: To explore young men's perceptions of (i) the risk for themselves and their partners in connection with unprotected intercourse, and (ii) the main barriers to practising safe sex. Methods:Qualitative latent content analysis of interviews involving 22 Swedish males aged 16-20, who requested a Chlamydia test. Results: The main categories identified were: (1) Low perceived threat regardin

Objective. To explore Swedish women's experiences of clinical abortion care in relation to their need for existential support. Methods. Individual in-depth interviews with 24 women with previous experience of unwanted pregnancy and abortion. Participants were recruited between 2006 and 2009. Interviews were analysed by latent content analysis. Findings. Although the women had similar experiences o

Background. Sweden has the highest abortion numbers among the Nordic countries. Since 1995, the abortion rate among teenagers has increased by nearly 50%. We therefore undertook a study where the overall aim was to gain a deeper understanding on which factors female teenagers believe may explain the increasing numbers of teenage abortions. Teenagers' perceptions of teenage pregnancy, abortion, sex

Gross primary production (GPP) of the vegetation is the largest carbon exchange process of the global carbon cycle. Currently, within satellite-based remote sensing, GPP is generally modelled using linear light use efficiency models where GPP is related to photosynthetically active radiation absorbed by the green vegetation (APAR). These models work well on moderate to low spatiotemporal averaging

The angular correlations between charged Ξ baryons and associated identified hadrons (pions, kaons, protons, Λ baryons, and Ξ baryons) are measured in pp collisions at s = 13 TeV with the ALICE detector to give insight into the particle production mechanisms and balancing of quantum numbers on the microscopic level. In particular, the distribution of strangeness is investigated in the correlations

Study design: Longitudinal prospective cohort study. Objectives: To assess the effects of Active Rehabilitation (AR) training programmes for individuals with spinal cord injury (SCI) on physical independence, self-efficacy and wheelchair skills, and to identify factors that are associated with gains in these outcomes. Setting: Eight consecutive AR programmes in Sweden. Methods: Participants (n = 1

Objectives: Preconception care is important for the screening, prevention and management of risk factors that affect pregnancy outcomes. We aimed to investigate pre-pregnancy care policies, guidelines, recommendations and services in six European countries. Methods: In 2013, an electronic search and investigation was undertaken of preconception policy, guidelines, recommendations and services avai

Objective. To evaluate an intervention involving advance provision of emergency contraceptive pills (ECP) to Swedish teenage girls. Material and methods. Some 420 girls aged 15-19, requesting ECP at a local youth clinic were randomly assigned to intervention group (IG) (n=214) or control group (CG) (n=206). Both groups received ECP on request. The IG received one extra dose of ECP, condoms and an Objective. To evaluate an intervention involving advance provision of emergency contraceptive pills (ECP) to Swedish teenage girls.
