Migratory birds regularly perform impressive long-distance flights, which are timed relative to the anticipated environmental resources at destination areas that can be several thousand kilometres away. Timely migration requires diverse strategies and adaptations that involve an intricate interplay between internal clock mechanisms and environmental conditions across the annual cycle. Here we revi
Transdisciplinary research and collaboration is widely acknowledged as a critical success factor for solution-oriented approaches that can tackle complex sustainability challenges, such as biodiversity loss, pollution, and climate-related hazards. In this context, city governments’ engagement in transdisciplinarity is generally seen as a key condition for societal transformation towards sustainabi
A sorption isotherm expresses the relation between ambient relative humidity (RH) and equilibrium moisture content of a material for a specific temperature. The sorption isotherm can generally be divided into a hygroscopic part covering low, medium and high RH levels, and an over-hygroscopic part close to 100% RH. For wood, the hygroscopic part is dominated by water uptake in cell walls and the ov
In order to fulfil the requirements of available energy resources, there is a great need to obtain a sustainable and environmentally friendly energy utilization using combustion processes. In order to do this, it is of utmost importance to utilize non-intrusive diagnostic techniques with high spatial and temporal resolution which can characterize the combustion process and also validate combustion
Introduction: Lactate concentration is known to be a strong predictor of mortality, but is not included in any of the major intensive care scorings systems such as the Simplified Acute Physiology Score (SAPS 3). The objective of this study was to investigate the prognostic value of lactate concentration when combined with SAPS 3. Materials and methods: In the period of 2008 to June 2017 the genera
Aims. We aim to study the variability properties of bright hard X-ray selected active galactic nuclei (AGN) in the redshift range between 0.3 and 1.6 detected in the Chandra Deep Field South (XMM-CDFS) by a long (∼3 Ms) XMM observation. Methods. Taking advantage of the good count statistics in the XMM CDFS, we search for flux and spectral variability using the hardness ratio (HR) techniques. We al
During substrate-limited growth, some strains of Thiosphaera pantotropha nitrify heterotrophically and denitrify aerobically. These processes are thought to be used as NADH overflow mechanisms, resulting from a restricted oxygen respiration capacity. In this study, the behavior of T. pantotropha regarding the NADH overflow in the presence of substantial concentrations of substrate was examined. Co
PURPOSE: To describe and evaluate the new rapid SITA Fast computerized perimetric threshold strategy.METHOD: Computer simulations of visual fields were used to develop a new rapid threshold strategy, SITA Fast. In a clinical evaluation 30 patients were examined twice with each of the Full Threshold, Fastpac and SITA Fast strategies.RESULTS: SITA Fast had significantly shorter test time using on av
Inside-out submitochondrial particles (IO-SMP) were isolated and purified from potato (Solanum tuberosum L. cv.) tubers. When these IO-SMP were incubated with [γ32P]ATP more then 20 proteins became labelled as a result of phosphorylation. The 32P incorporation was stimulated by the oxidizing reagent ferricyanide. Except for a 17 kDa protein which was phosphorylated only in the absence of divalent
Background: To establish integrated healthcare pathways for patients with neurodevelopmental disorders (ND) such as autism spectrum disorder and attention-deficit hyperactivity disorder is challenging. This study sets out to investigate the main concerns for healthcare professionals when integrating ND care pathways and how they resolve these concerns. Methods: Using classic grounded theory (Glase
A housing adaptation (HA) can enable independent living in one's own home, but deciding to change the home environment can be a thought-provoking matter. The aim of this study was to explore the applicant's perspective and decision-making process when applying for an HA grant. Seventeen persons were interviewed about their application for such a grant, and the data were analyzed using a constant c
The conversion of technical lignin into valuable chemicals is important for the complete utilization of lignocellulose. The kraft process dominates the pulp industry, and large amounts of kraft lignin are produced worldwide. However, the complexity of lignin limits its valorization. In this study, a kraft lignin, Indulin AT, was depolymerized under base conditions, and the effects of substrate loa
Lantbruket rankas konsekvent som en av de mest riskfyllda sektorerna i Sverige såväl som i många andra delar av världen. Förutom lidande för den enskilde beräknas dödliga och icke dödliga skador i svenskt lantbruk kosta samhället 2 – 3 miljarder kr per år. I Sverige inträffade det cirka 5 000 olyckor på jordbruksföretag 2004. Detta innebar att minst en olycka inträffade på 8% av svenska gårdar som
Is there a variation in facial ideals depending on ethnic background that affects judgements of outcome in orthognathic surgery? How does the evaluation correlate with patient-reported outcome measures? Two evaluation panels, Singaporean and Swedish, judged photographs of patients undergoing orthognathic surgery taken before and after operation. Improvement in facial aesthetics was calculated betw
The least absolute shrinkage and selection operator (LASSO) algorithm is a promising method for sparse source location in time–division multiplexing (TDM) multiple–input, multiple– output (MIMO) radar systems, with notable performance gains in regard to resolution enhancement and side lobe suppression. However, the current batch LASSO algorithm suffers from high– computational complexity when deal
In this paper, we propose a novel 3-DOF visual odometry method to estimate the location and pose (yaw) of a mobile robot when the robot is navigating indoors. Particularly, we mainly aim at dealing with the corridor-like scenarios where the RGB-D camera mounted on the robot can capture apparent planar structures such as floor or walls. The novelties of our method lie in two-folds. First, to fully
When it comes to the field of drug studies, researchers have tended to privilege men’s perspectives and experiences, assuming women to be mostly marginal, as primarily victims and accomplices. Further, when women’s experiences are taken into account, a view of them as only women has tended to be pushed to the forefront. As such, we are sorely lacking research departing from women’s own recollectio
Software reliability is an important characteristic for most systems, but due to its dynamic properties it is hard to assess until very late in the development. Nevertheless, the testing must be planned to meet the reliability requirements. In test planning, the notion of usage coverage may be used as an indicator of reliability as they are correlated with each other. When the testing is planned,
