Popular Abstract in English Darwin’s masterpiece “On the origin of species” describes how populations (one group of individuals from the same species that can easily mate with each other and that occupy the same geographic area) evolve through the process of natural selection, which can be shortly abbreviated as the survival of the fittest. More specifically, the individuals within one population The gene (Pgi) encoding the enzyme phosphoglucose isomerase (PGI) which plays a central role in the main pathways of carbon metabolism has been shown to be of adaptive significance in a wide range of different species. Earlier studies of enzyme electromorph variation in the grass Festuca ovina suggest that variation in cytosolic PGI (PGIC) may be involved in the adaptive response of F. ovina to th

To provide for a high QoS in a cellular network, each call should be assigned to its preferred cell and priority given to already ongoing calls. Herein, a combined speed-sensitive layer selection method and dynamic guard channel scheme, called CLARR, for use in hierarchical networks, is introduced. To reduce the complexity, partially the same speed estimation and measurement procedures are applied

In this paper the phenomenon of pluralistic ignorance is discussed and it is argued why it is of relevance for epistemic logic and social psychology. Roughly put, pluralistic ignorance is the case when a group of interacting agents all experience a discrepancy between their private opinions and the perceived opinions of the others. After introducing the phenomenon, numerous features of pluralistic

Realistic and accurate reconstructions of past vegetation cover are necessary to study past environmental changes. This is important since the effects of human land-use changes (e.g. agriculture, deforestation and afforestation/reforestation) on biodiversity and climate are still under debate. Over the last decade, development, validation, and application of pollen-vegetation relationship models h

Environmental research infrastructures are often built on a large number of distributed observational or experimental sites, run by hundreds of scientists and technicians, financially supported and administrated by a large number of institutions. It becomes very important to acknowledge the data sources and their providers. There is also a strong need for common data citation tracking systems that

Lung transplantation is currently the only option for patients with end-stage respiratory diseases, but owing to various complications and adverse effects of the treatment in combination with the increasing demand for and limited access to donor organs, new strategies are needed. Recent advances in materials science, culture techniques, cell-phenotyping and isolation techniques, bioreactor enginee

Background and ObjectivesEEG is widely used for prediction of neurologic outcome after cardiac arrest. To better understand the relationship between EEG and neuronal injury, we explored the association between EEG and neurofilament light (NfL) as a marker of neuroaxonal injury, evaluated whether highly malignant EEG patterns are reflected by high NfL levels, and explored the association of EEG bac

Fishing access agreements with developing countries have been widely criticized, for example for contributing to overexploiting fish resources and threatening food security. However, there is littlequantitative evidence of their economic effects. We investigate how European Union (EU) fishing access agreements affect African partner countries’ fishery exports to OECD countries. We find that:• Fish

Since the Middle Ages, there have been Crown estates in Sweden that were to be used by the King. In 1809-10, an agreement was reached between King and Parliament about the financing of the expenses of the Royal Family and the Royal Household and of the right of the King and the Royal Family to use and govern the Royal Palaces. This agreement is still in force, although it has been amended as regar

This study uniquely combines advanced continental-scale data from two distinct sources: pollen-based past land cover (paleoecology) and ancient DNA (aDNA), developing a novel statistical model for spatiotemporal reconstructions of past land use across Europe. This groundbreaking approach integrates paleo-pollen and aDNA data, providing unprecedented insights into the environmental impacts of Holoc

Introduction: Risk evaluation for preeclampsia in early pregnancy allows identification of women at high risk. Prediction models for preeclampsia often include circulating concentrations of placental growth factor (PlGF); however, the models are usually limited to a specific PlGF method of analysis. The aim of this study was to compare three different PlGF methods of analysis in a Swedish cohort t

Listening in public diplomacy is a rather new topic in academic discussions. Early public diplomacy scholarship was dominated, and in large degree continues to be dominated, by a focus on crafting messages and influencing. The more recent focus on relationship management and collaborative public diplomacy allowed for discussions about another role for listening. Yet, as some scholars pointed out,

Background: Apnea of prematurity is a common problem in preterm infants that may have significant consequences on their development. Methylxanthines (aminophylline, theophylline, and caffeine) are effective in the treatment of apnea of prematurity. Doxapram is used as a respiratory stimulant in cases refractory to the methylxanthine treatment. Objectives: To evaluate the benefits and harms of doxa

Popular Abstract in Swedish Global uppvärmning, säkerhetspolitik och framtida minskad tillgång på fossila bränslen har de senaste åren skyndat på sökandet efter nya, förnyelse-bara drivmedel. Användningen av bioetanol har ökat avsevärt och är idag ett av de vanligaste biobränslena i världen. Idag framställs bioetanol vanligen genom jäsning av socker från socker-rör eller från stärkelse (från tillFuel ethanol from lignocellulose is one sustainable alternative to the fossil fuels of today. All sugars in the material must be utilized in order to achieve high overall ethanol yields. Baker’s yeast, Saccharomyces cerevisiae, has been engineered to ferment the pentose sugar xylose from lignocellulose to ethanol. However, ethanol production from xylose is slow and often incomplete. In this work s
