Evaluation of air-soil temperature relationships simulated by land surface models during winter across the permafrost region

A realistic simulation of snow cover and its thermal properties are important for accurate modelling of permafrost. We analyse simulated relationships between air and near-surface (20 cm) soil temperatures in the Northern Hemisphere permafrost region during winter, with a particular focus on snow insulation effects in nine land surface models, and compare them with observations from 268 Russian st

In search of the severity dimension of traffic events: Extended Delta-V as a traffic conflict indicator

Most existing traffic conflict indicators do not sufficiently take into account the severity of the injuries resulting from a collision had it occurred. Thus far, most of the indicators that have been developed express the severity of a traffic encounter as their proximity to a collision in terms of time or space.This paper presents the theoretical framework and the first implementation of Extende

The effect of baking and enzymatic treatment on the structural properties of wheat starch

In this study, bread was baked with and without the addition of α-amylase. Starch was extracted from the baked bread and its molecular properties were characterized using 1H NMR and asymmetric flow field-flow fractionation (AF4) connected to multi-angle light scattering (MALS) and other detectors. The approach allows determination of molar mass, root- mean-square radius and apparent density as wel

Labor market consequences of childhood onset type 1 diabetes

This paper examines the effect of the onset of Type 1 Diabetes Mellitus (T1DM) before 15 years of age on labor market outcomes and contributes to the literature on effects of childhood health on adult socioeconomic status. Using national Swedish socioeconomic register data 1991–2010 for 2485 individuals born 1972–1978 with onset of T1DM in 1977–1993, we find that T1DM in childhood has a negative e

Effects of an 8-year childhood physical activity intervention on musculoskeletal gains and fracture risk

Background Physical activity (PA) in childhood is associated with musculoskeletal benefits while the effect on fracture risk is yet to be determined. The aim of this study was to evaluate whether extension of a PA intervention leads to improvement in musculoskeletal traits with an accompanied reduced fracture risk. We hypothesized that the PA program would have beneficial effects in both sexes, bu

Colour in the eye of the beholder : receptor sensitivities and neural circuits underlying colour opponency and colour perception

Colour vision — the ability to discriminate spectral differences irrespective of variations in intensity — has two basic requirements: (1) photoreceptors with different spectral sensitivities, and (2) neural comparison of signals from these photoreceptors. Major progress has been made understanding the evolution of the basic stages of colour vision–opsin pigments, screening pigments, and the first

From REDD+ forests to green landscapes? Analyzing the emerging integrated landscape approach discourse in the UNFCCC

This paper explores an emerging discourse at the UNFCCC level - the integrated landscape approach discourse, which brings new understandings of how to approach forests in a climate change nexus. Its proponents argue that forestry, agriculture and other land uses cannot be seen in isolation, but need to be integrated into a single management process. I apply argumentative discourse analysis (Hajer,

Transient transport of heat, mass, and momentum in paperboard including dynamic phase change of water

A theory to describe deforming moist paperboard in environments where both temperature and pressure change significantly during a short period of time is presented. Paperboard is viewed as an orthotropic triphasic porous medium consisting of fibers, bound water and moist air. Furthermore, the moist air is considered as a mixture of two miscible gases, namely dry air and water vapor. A two–scale hy

Post-cardiac arrest care. Targeted temperature management and coronary care.

AbstractOut-of-hospital cardiac arrest is a devastating manifestation of coronary artery disease. For patients who are initially resuscitated and are admitted to an intensive care unit, mortality is high. Roughly half of all patients die, primarily due to neurological injury. In recent years, some improvement in outcomes has been seen, perhaps in some part due to interventions performed in hospita

Recognition of out-of-hospital cardiac arrest by medical dispatchers in emergency medical dispatch centres in two countries

Introduction Survival after out-of-hospital cardiac arrest (OHCA) remains low. Early recognition by emergency medical dispatchers is essential for an effective chain of actions, leading to early cardiopulmonary resuscitation, use of an automated external defibrillator and rapid dispatching of the emergency medical services. Aim To analyse and compare the accuracy of OHCA recognition by medical dis

Dissociation of metabolic and hemodynamic levodopa responses in the 6-hydroxydopamine rat model

Dissociation of vasomotor and metabolic responses to levodopa has been observed in human subjects with Parkinson's disease (PD) studied with PET and in autoradiograms from 6-hydroxydopamine (6-OHDA) rat. In both species, acute levodopa administration was associated with increases in basal ganglia cerebral blood flow (CBF) with concurrent reductions in cerebral metabolic rate (CMR) for glucose in t

A field study of fluorescent and LED classroom lighting

Indoor lighting is facing a massive retrofit to LED lighting. Research is needed to assess whether LED-based lighting can promote energy efficiency, boost visual comfort and support biological functions. This field study considered the lighting of four identical classrooms in an upper secondary school in Helsingborg, Sweden. Two classrooms were fitted with state-of-the-art ceiling pendants contain

Epigenetic markers to further understand insulin resistance

Epigenetic variation in human adipose tissue has been linked to type 2 diabetes and its related risk factors including age and obesity. Insulin resistance, a key risk factor for type 2 diabetes, may also be associated with altered DNA methylation in visceral and subcutaneous adipose tissue. Furthermore, linking epigenetic variation in target tissues to similar changes in blood cells may identify n

Code Generation for Custom Architectures using Constraint Programming

The computation power we expect from the various smart devices we use keeps increasing. Not only do we want faster devices but also less power hungry and energy efficient devices, both for the environment and our personal convenience (remember that "mobile phone" attached to a power plug at all times?).One way of addressing this demand is to build custom processor architectures that focus on a spe

Early adolescents’ motivations to defend victims in school bullying and their perceptions of student–teacher relationships : A self-determination theory approach

The aim of this study was to investigate whether various dimensions of student–teacher relationships were associated with different types of motivation to defend victims in bullying and to determine the association between these types of motivations and various bystander behaviors in bullying situations among early adolescents in Italy. Data were collected from 405 Italian adolescents who complete

Vegetation-climate feedbacks modulate rainfall patterns in Africa under future climate change

Africa has been undergoing significant changes in climate and vegetation in recent decades, and continued changes may be expected over this century. Vegetation cover and composition impose important influences on the regional climate in Africa. Climate-driven changes in vegetation structure and the distribution of forests versus savannah and grassland may feed back to climate via shifts in the sur

Coordination between governance actors in universities : the role of policy documents

This article focuses on coordination between governance actors in a public university. The purpose of this paper is to illustrate and analyze policy documents as governance tools that allow departmental management to coordinate with the authorities, the board, and the management at different university levels. A central finding is that the importance of policy documents as governance tools takes e
