Do Nitrogen and Phosphorus Additions Affect Nitrogen Fixation Associated with Tropical Mosses?

Tropical cloud forests are characterized by abundant and biodiverse mosses which grow epiphytically as well as on the ground. Nitrogen (N)-fixing cyanobacteria live in association with most mosses, and contribute greatly to the N pool via biological nitrogen fixation (BNF). However, the availability of nutrients, especially N and phosphorus (P), can influence BNF rates drastically. To evaluate the

Slow conformational changes in the rigid and highly stable chymotrypsin inhibitor 2

Slow conformational changes are often directly linked to protein function. It is however less clear how such processes may perturb the overall folding stability of a protein. We previously found that the stabilizing double mutant L49I/I57V in the small protein chymotrypsin inhibitor 2 from barley led to distributed increased nanosecond and faster dynamics. Here we asked what effects the L49I and I

Oxygen saturation mapping during reconstructive surgery of human forehead flaps with hyperspectral imaging and spectral unmixing

BACKGROUND: Optical spectroscopy is commonly used clinically to monitor oxygen saturation in tissue. The most commonly employed technique is pulse oximetry, which provides a point measurement of the arterial oxygen saturation and is commonly used for monitoring systemic hemodynamics, e.g. during anesthesia. Hyperspectral imaging (HSI) is an emerging technology that enables spatially resolved mappi

LONG-TIME BEHAVIOR AND STABILITY FOR QUASILINEAR DOUBLY DEGENERATE PARABOLIC EQUATIONS OF HIGHER ORDER

We study the long-time behavior of solutions to quasilinear doubly degenerate parabolic problems of fourth order. The equations model, for instance, the dynamic behavior of a non-Newtonian thin-film flow on a flat impermeable bottom and with zero contact angle. We consider a shear-rate dependent fluid the rheology of which is described by a constitutive power law or Ellis law for the fluid viscosi

Adapting Household Energy Consumption: How Consumers in Germany and Sweden Managed the European Energy Crisis

Residential energy consumption in Europe is unsustainable, relying heavily on fossil fuels and contributing to climate change. The European energy crisis, as a naturally occurring experiment, disrupted energy consumption in households due to drastically increased prices and raised public awareness while creating a unique opportunity to study the dynamics of change in household energy consumption.

The life of young working class mothers in Sweden

Which are the features marking modern motherhood? Our attempts to answer this are based on an investigation among young working-class mothers. Our focus is norms pertaining to the relation between mother and child. Some of these seem distinctly subcultural working-class norms, while others are supposed to be more general. However, norms here presented are held to be the marks of young families, in

The Modern Poor: On the Sociological Position of Social-Aid Clients

The social-aid institution has been analyzed almost exclusively from a social problems approach, aiming at the understanding of social aid clients as a social problem. This article views them from a different angle, as a sociological category occupying a unique position in society. Following Simmel, we deal here with those who are poor in a social sense, i.e., anyone receiving public assistance. I

Population-based prognostic instrument (SweMR 2.0) for melanoma-specific survival - An ideal tool for individualised treatment decisions for Swedish patients

INTRODUCTION: The prognosis for patients with melanoma has improved due to better treatments in recent years and updated tools to accurately predict an individual's risk are warranted. This study aims to describe a prognostic instrument for patients with cutaneous melanoma and its potential as a clinical device for treatment decisions.METHODS: Patients with localised invasive cutaneous melanoma di

Model ensembles of ecosystem services fill global certainty and capacity gaps

Sustaining ecosystem services (ES) critical to human well-being is hindered by many practitioners lacking access to ES models (“the capacity gap”) or knowledge of the accuracy of available models (“the certainty gap”), especially in the world’s poorer regions. We developed ensembles of multiple models at an unprecedented global scale for five ES of high policy relevance. Ensembles were 2 to 14% mo

Cobalt nanoparticles cause allergic contact dermatitis in humans

Background: Cobalt (Co) causes allergic contact dermatitis (ACD) and the emerging use of Co nanoparticles (CoNPs) warrants gaining further insight into its potential to elicit ACD in sensitized individuals. Objectives: The aims of the study were to clarify to what extent CoNPs may elicit ACD responses in participants with Co contact allergy, and to evaluate whether the nanoparticles cause a distin

Sub-Picosecond Carrier Dynamics Explored using Automated High-Throughput Studies of Doping Inhomogeneity within a Bayesian Framework

Bottom–up production of semiconductor nanomaterials is often accompanied by inhomogeneity resulting in a spread in electronic properties which may be influenced by the nanoparticle geometry, crystal quality, stoichiometry, or doping. Using photoluminescence spectroscopy of a population of more than 11 000 individual zinc-doped gallium arsenide nanowires, inhomogeneity is revealed in, and correlati

The Reflection Pier - A Hospital Safe Haven

Hospitals have been a crucial element of healthcare for centuries, providing a space for diagnosis, treatment, and recovery. The design of hospitals has evolved dramatically throughout history, with significant changes in both the form and function of these institutions. Ancient hospitals were closely connected to nature, with an emphasis on the role of surroundings in the healing process. However

The importance of context-a qualitative study exploring healthcare practitioners' experiences of working with patients at home after a stroke

BACKGROUND: Stroke significantly impacts individuals, leading to the need for long-lasting rehabilitation and adaptation to environmental demands. Rehabilitation after stroke is increasingly performed in patients' homes, and it is argued that rehabilitation in this context is more person-centred and positively impacts client outcomes. However, the role of environmental factors in this process is l

Phosphorus regulates ectomycorrhizal fungi biomass production in a Norway spruce forest

Ectomycorrhizal fungi (EMF) are important components of soil microbial communities, and EMF biomass can potentially increase carbon (C) stocks by accumulating in the soils as necromass and producing recalcitrant structures. EMF growth depends on the C allocated belowground by the host trees, and the nutrient limitation on tree growth is expected to influence this allocation. Therefore, studying EM
