Among plants, gender dimorphism occurs in about 10% of all angiosperms and more than 50% of all moss taxa, with dwarf males (DM) found exclusively in some unisexual mosses. In this study, we explore the role of male dwarfism as a reproductive strategy in the widespread acrocarpous moss Dicranum scoparium, which has facultative male dwarfism, having both dwarf males (DMs) and normal-sized males (NM
OBJECTIVE: The optimal target heart rate in patients with prevalent atrial fibrillation (AF) is not well defined. The aim of this study was to analyse the associations between heart rate and adverse outcomes in a large contemporary cohort of patients with prevalent AF.METHODS: From two prospective cohort studies, we included stable AF outpatients who were in AF on the baseline ECG. The main outcom
We explore the interplay of electron-electron correlations and surface effects in the prototypical correlated insulating material, NiO. In particular, we compute the electronic structure, magnetic properties, and surface energies of the (001) and (110) surfaces of paramagnetic NiO using a fully charge self-consistent DFT+ dynamical mean-field theory method. Our results reveal a complex interplay b
Ekosystemtjänster är alla nyttor som ett fungerande ekosystem ger människan. Att bevara jordbruksmarkens ekosystemtjänster kan vara kostsamt för jordbrukare och då krävs det att de nyttor som tjänsterna ger syns och att bevarandet av ekosystemtjänster är lönsamt. Vi har utvecklat verktyg för att kvantifiera och värdera ekosystemtjänster. Vi presenterar dessa verktyg och visar att:- När det blir lä
Alexander Lingas, Anna Stavrakopoulou, and Thomas Arentzen discuss and present the poetry and music of Byzantium's most outstanding female composer.
Miljöersättningar i landsbygdsprogrammet kritiseras för att inte vara kostnadseffektiva eller attraktiva för många jordbrukare,samt för att inte ta vara på jordbrukarnas kompetens och kreativitet för att lösa miljöproblem. Problemen beror i hög grad på attersättningen betalas ut oavsett storleken på miljöeffekten, bara den avtalade åtgärden utförs. Utvecklingen av ett effektivare system för miljöe
Det pågår en intensiv debatt om hur vi bäst kan använda skogen som resurs. Att ersätta fossila bränslen med förnybara bränslen från den svenska skogen lyfts fram som ett sätt att bidra till klimatmål. Men ett ökat uttag av biomassa kräver att skogen brukas mer intensivt vilket kan vara negativt för en rad andra samhällsmål som skogen bidrar till. Vad skulle ett intensivare skogsbruk totalt sett be
Enligt EU-kommissionen är den gemensamma jordbrukspolitiken central för att nå FN:s globala mål för hållbar utveckling. Nästan 40 procent av EU:s budget går till jordbruksstöd, men i vilken utsträckning stöden bidrar till att uppnå FN-målen är oklart. Vi analyserar hur de 551 miljarder kronor som betalades ut i stöd år 2015 fördelades mellan FN:s 17 hållbarhetsmål. Vi finner att:* 60 procent av st
Postural orthostatic tachycardia syndrome (POTS) is a cardiovascular autonomic disorder with poorly understood etiology and underlying pathophysiology. Since cardiovascular morbidity has been linked to growth hormone (GH), we studied GH levels in patients with POTS. We conducted an age-sex-matched case-control study in patients with POTS (age 31 ± 9 years; n = 42) and healthy controls (32 ± 9 year
OBJECTIVE: Mortality caused by coronary artery disease has markedly decreased in recent years. However, a substantial proportion of patients suffering a coronary event (CE) die within the first day, most of them out of hospital. We aimed to investigate how established cardiovascular (CV) risk factors and CV autonomic indices associate with fatal versus non-fatal CEs in the population.METHODS: 33 0
Airway basal cells are crucial for regeneration of the human lung airway epithelium, and are thought to be important contributors to Chronic Obstructive Pulmonary Disease (COPD) and other lung disorders. In order to reveal how basal cells contribute to disease, and to discover novel therapeutic targets, these basal cells need to be further characterized. In this study, we optimized a flow cytometr
The Intermediate Data Structure (IDS) was developed as a strategy aimed at standardizing the dissemination of micro-level historical demographic data. The structure provides a common and clear data strategy which facilitates studies that consider several databases, and the development and exchange of software. Based on my own experiences from working with the IDS, in this article I provide reflect
Mounting evidence shows that early-life adversity negatively affects health in late life, but much less is known about if and how early-life conditions affect health in mid-life. In particular, knowledge is very limited regarding the connection between early-life adversity and reproductive health. This paper studies the effect of early-life disease exposure on women’s reproductive careers in mid-l
Background: It is currently estimated that one third of all children will sustain fractures. However, there may also be time trends in pediatric fracture incidence. When predicting future fracture incidence, it is further important to evaluate bone mass, as low bone mass is a strong predictor of fractures. Such evaluation would help the society to allocate health care resources adequately. Aims: T
Objectives The recovery after tonsil surgery is often troublesome for children and caregivers often feel insecure regarding optimal post-operative care for their children at home. The aim was to study what the current literature reports regarding the effect of post-operative telephone counselling and Internet support on pain and recovery after paediatric tonsil surgery. Method A systematic literat
While Sweden is positioned as one of the most gender equal countries in the world, survey-reported rates of intimate partner violence against women (IPVAW) are here among the highest in the EU. This apparently contradictory co-existence of high levels of gender equality and of IPVAW rates in Sweden and other Nordic countries, which has been termed the Nordic Paradox, has hitherto not been adequate
