Multiple Stressors Simplify Freshwater Food Webs

Globally, freshwater ecosystems are threatened by multiple stressors, yet our knowledge of how they interact to affect food web structure remains scant. To address this knowledge gap, we conducted a large-scale mesocosm experiment to quantify the single and combined effects of three common anthropogenic stressors: warming, increased nutrient loading, and insecticide pollution, on the network struc

Adrenaline has a limited effect on myocardial microvascular blood flow : A randomised experimental study in a porcine cardiac arrest model

Background: Adrenaline (ADR) is a cornerstone of advanced life support (ALS) in cardiac arrest (CA), although its neurologically favourable survival outcomes remain unclear. ADR increases coronary perfusion pressure (CPP), with levels >15 mmHg associated with successful defibrillation. This study aimed to elucidate the relationship between ADR, myocardial microvascular blood flow, and resuscitatio

Supporting access and implementation of agricultural extension services for female smallholder farmers : a systematic review

Women have always played a central role in smallholder agriculture in many farming systems of the Global South. However, they have had, and still have, low access to agricultural information, and even less ability to enact on training or advice received, in comparison to male farmers. The paper investigates what is needed for female smallholders to better benefit from agricultural advice and train

The forgotten element: : Why do we ignore calcium in otolith studies?

Typical analyses of otolith microchemistry use calcium, a major constituent, as an internal standard, setting its value as a constant and ignoring any potential variations. In fact, patterns do occur in otolith Ca deposition, as can be observed either by repeating the analysis, by creating two-dimensional maps of Ca, or both. Here we present evidence of Ca variations in fish otoliths from analyses

Expressives, directives and assertions : Cognitive dimensions of speech acts

Despite the considerable amount of research devoted to speech act theory, relatively little attention has been paid to the cognitive foundations underlying different speech act classes. This article addresses this gap by introducing a framework of cognitive dimensions associated with the performance of expressives, directives and assertions. Drawing on empirical data, we argue that each class requ

Incidence of Adult Acquired Flatfoot Deformity Referred to Specialist Care in Sweden

Introduction: Adult acquired flatfoot deformity (AAFD) is a disabling condition that may require complex surgical treatment. Little is known about the incidence of AAFD in the general population and specifically of AAFD requiring specialist care. We aimed to describe the incidence of AAFD referred to specialist care in the Swedish general population. Methods: We conducted a nation-wide epidemiolog

Understanding land use impacts of croplands on biodiversity through UNEP's Global Guidance for Life Cycle Impact Assessment

In a global retrospective assessment, this study quantifies the potential impacts of croplands on biodiversity using the UNEP-Life Cycle Initiative's recommended method for land use that was proposed by the GLAM consensus working group for Global Guidance for Life Cycle Impact Assessment Indicators and Methods. The findings show the importance of using tools that account for both occupied area and

Injectable Functional Polymeric Cryogels for Biological Applications

In recent years, injectable cryogels have been frequently used in various biomedical applications such as tissue engineering, drug delivery, therapeutics, therapy, cell transplantation and immunotherapy. Cryogels, one of the biomaterials with injectable 3D scaffold structures, have important properties such as biocompatibility, physical resistance, macropore and sensitivity. In addition to being b

Apolipoprotein E3 and E4 isoforms exhibit differing effects in countering endotoxins

Apolipoprotein E (APOE) is distributed across various human tissues and plays a crucial role in lipid metabolism. Recent investigations have uncovered an additional facet of APOE's functionality, revealing its role in host defense against bacterial infections. To assess the antibacterial attributes of APOE3 and APOE4, we conducted antibacterial assays using Pseudomonas aeruginosa and Escherichia c

Deficiency of Peptidylglycine-alpha-amidating Monooxygenase, a Cause of Sarcopenic Diabetes Mellitus

Context: Peptidylglycine-α-amidating monooxygenase (PAM) is a critical enzyme in the endocrine system responsible for activation, by amidation, of bioactive peptides. Objective: To define the clinical phenotype of carriers of genetic mutations associated with impaired PAM-amidating activity (PAM-AMA). Design: We used genetic and phenotypic data from cohort studies: the Malmö Diet and Cancer (MDC;

Patterns of systolic blood pressure response at the end of exercise and mortality and morbidity in patients referred for exercise testing

Objectives Peak exercise systolic blood pressure (SBP) is associated with future cardiovascular disease (CVD) and mortality. We aimed to evaluate the predictive value of different SBP patterns at the end of exercise with these outcomes. Methods We studied 6329 adults (45% women) referred for exercise testing, with test duration of 6-14 min, maximal effort and valid SBP measurements at the end of e

Characterizing microplastics in biofertilizer. Insights into particle properties and environmental impact

Karakterisering av mikroplaster i biogödsel - insikter i partikelegenskaper och miljöpåverkan Mikroplaster i biogödsel kan bidra till att sprida giftiga föroreningar i miljön. När all vår plast bryts ner till mikro-plaster och hamnar i naturen kan den sprida toxiska ämnen och problem långt bortom den ursprungliga källan. Bio-gödsel från våra hushållssopor kan upplevas som en grön lösning – men deThe significant increase in global plastic production has led to its widespread environmental accu-mulation. Soil has become a major sink for microplastics, originating from sources like biofertilizers. This study aims to link the characteristics of microplastics in biofertilizer with their possible envi-ronmental effects, specifically focusing on the sorption of contaminants. Microscopy was emplo

Konst i (gt) klimat

Klimatfrågan är ett ämne som många människor pratar om. De senaste årtiondena har klimatfrågan ökat i samband med ökade utsläpp. Effekterna av utsläppen är tydliga i form av höjda vattennivåer, värmeböljor, extremväder och skyfall för att nämna några. Vad människor gör åt saken beror mycket på hur medvetna människor är om klimatförändringarna. Vissa personer märker inte av klimatförändringarna medClimate change is an important topic for a lot of people and the usage of art to draw attention towards the issue is not a novel idea. Each art piece has had a different approach to, not only increase awareness but to also portray climate change. The expressions vary depending on who made the art piece, the context of its creation and similar parameters. Globally, this has been done since at least

Räddningstjänstens insatsmöjligheter vid händelser i större batterilager

Battery energy storage systems (BESS) are becoming increasingly important for storing energy, particularly renewable energy, and stabilizing electricity grids. These systems often use lithium-ion batteries, which are efficient but pose risks during accidents. Rapid implementation of BESS has led to uncertainties in regulations and emergency response protocols. This thesis aims to identify and eval

Exploring Co-cultivation Strategies of Nitrogen-Fixing Bacteria and Recombinant Yeast for Sustainable Biomanufacturing

To reduce reliance on energy-intensive, chemically synthesised nitrogen sources in microbial cultivation, we investigated the integration of the nitrogen-fixing bacterium Azotobacter vinelandii into a bioconversion process with the recombinant yeast Saccharomyces cerevisiae. Our objective was to develop a more sustainable approach by utilising biological nitrogen fixation to supply ammonium direct

Non-Planar 3D Printing - Inspired by the Efficiency of Spider Webs

This project investigates non-planar 3D printing techniques using a robotic system and Polylactic Acid (PLA) filament, drawing inspiration from the spider web’s structure. The primary aim is to develop methods that optimise material usage while maximising print coverage over large areas. Ultimately, the research seeks to expand the capabilities of robotic manufacturing and uncover new architectura
