N. antarctica occurs in the widest range of habitat types among all South American Nothofagus. The aim of this Study is to investigate adaptive responses by variation in morphological (tree form and leaf characters), and environmental traits (soils) of the polymorphic N. antarctica. Also we analyze the effect of genetic drift and limited gene flow in such predominantly apomict by means of neutral

Three previously published control strategies for anaerobic digestion were implemented in Simulink/Matlab using Anaerobic Digestion Model No. 1 (ADM1) to model the biological process. The controllers' performance were then simulated and evaluated based on their responses from five different types of process scenarios i.e. start-up and steady state performance as well as disturbances from concentra

Single-file diffusion is a theoretically challenging many-body problem where the calculation of even the simplest observables, e.g. mean square displacement, for a tracer particle requires an elaborate mathematical machinery. There is therefore a need for simple approaches which provide intuitive understandings and predict qualitatively correct behaviours. Here we put forward a scaling-type method

ABSTRACT The aim of the present work was to compare patients with advanced cancer receiving specialized palliative home care with those receiving conventional care. A hospital-based advanced home care programme was initiated, in order to enable patients to remain at home for a longer period and to choose to die at home. The allocation to advanced home care (AHC) or conventional care (CC) was perf

Cerealier och andra fiberrika råvaror är näringsrika och innehåller, förutom kostfiber, olika bioaktiva substanser och mineralämnen. Dessa är nyckelingredienser för formulering av en rad nya livsmedel med hälsopotential.

Background: Emergency contraception (EC) is a type of modern contraception which is indicated after unprotected sexual intercourse when regular contraception is not in use. The importance of EC is evident in preventing unintended pregnancies and its ill consequences like unintended child delivery or unsafe abortion, which are the most common causes of maternal mortality. Therefore, EC need to be a

Associations between genotypes and cognitive outcomes may provide clues as to which mechanisms cause individual differences in old-age cognitive performance. We investigated the effects of five polymorphisms on cognitive functioning in a population-based sample of 2,694 persons without dementia (60-102 years). A structural equation model (SEM) was fit to the cognitive data, yielding five specific

The earthworm, Dendrobaena octaedra, is a common species in the uppermost soil and humus layers of coniferous forests and tundra in temperate and subarctic regions. The species is freeze-tolerant and may survive several months in a frozen state. Upon freezing, glycogen reserves are rapidly converted to glucose serving as a cryoprotectant and fuel for metabolism. In the present study we investigate

A multiscale modeling protocol was sketched for the trihexyltetradecylphosphonium chloride ([P-6,P-6,P-6,P-14]Cl) ionic liquid (IL). The optimized molecular geometries of an isolated [P-6,P-6,P-6,P-14] cation and a tightly bound [P-6,P-6,P-6,P-14]Cl ion pair structure were obtained from quantum chemistry ab initio calculations. A cost-effective united-atom model was proposed for the [P-6,P-6,P-6,P

This study explores mid-alpine ectomycorrhizal communities on Salix herbacea and Salix polaris in plant communities differing in nutrient status and snow conditions. Plant species were identified by tracking roots back to above ground structures while fungal species were identified using molecular methods. The fungi were identified to 34 molecular operational taxonomic units (MOTUs)/species but sp

Personalmotstånd anges ofta som ett problem vid förändringsarbete. I forskningen utgår man gärna från att motståndet beror på emotionella faktorer och man bortser från motståndets faktiska innehåll. I detta papper står detta innehåll i fokus och motstånd tolkas som en begäran om inflytande i ledningens beslutsfattande, med avseende på förändringen. Här väljer ledningen en strategi, som vid förändr

We have designed and tested economical large-area RF strip-line anodes made by silk-screening silver onto inexpensive plate glass, for use in microchannel plate photodetectors to provide measurements of time, position, integrated charge, and pulse waveform shapes. The 229-mm-long anodes are modular, and can be attached in series for economy in electronics channel-count. Measurements of the anode i

We report the discovery of light organs (photophores) adjacent to the dorsal defensive spines of a small deep-sea lanternshark (Etmopterus spinax). Using a visual modeling based on in vivo luminescence recordings we show that this unusual light display would be detectable by the shark's potential predators from several meters away. We also demonstrate that the luminescence from the spine-associate

In this work we report on the production of charged pions, kaons, and (anti) protons in pp and Pb - Pb collisions at root s(NN) = 2.76 TeV for 3 < P-T < 20 GeV/c. The evolution of the nuclear modification factor, R-AA, with collision centrality and transverse momentum is discussed.

We report on the identification and characterization of a mutated alcohol dehydrogenase 1 from the industrial Saccharomyces cerevisiae strain TMB3000 that mediates the NADH-dependent reduction of 5-hydroxymethylfurfural (HMF) to 2,5-bis-hydroxymethylfuran. The co-factor preference distinguished this alcohol dehydrogenase from the previously reported NADPH-dependent S. cerevisiae HMF alcohol dehydr

In this paper, we address distributed convergence to fair allocations of CPU resources for time-sensitive applications. We propose a novel resource management framework where a centralized objective for fair allocations is decomposed into a pair of performance-driven recursive processes for updating: (a) the allocation of computing bandwidth to the applications (resource adaptation), executed by t
