Identifying environmental factors that structure intraspecific genetic diversity is of interest for both habitat preservation and biodiversity conservation. Recent advances in statistical and geographical genetics make it possible to investigate how environmental factors affect geographic organisation and population structure of molecular genetic diversity within species. Here we present a study o

Many alloys undergo complex changes in local chemistry in the vicinity of weldments due to the thermal excursion during welding. The resulting changes in solute concentrations can lead to significant local variations in the unstrained unit cell parameter which, if not accounted for, can lead to serious error when determining residual stress by diffraction methods. Age-hardening aluminium alloys ar

Objective: A disturbed glucose metabolism has been observed in patients with aggressive behaviour. Interleukin (IL)-1β is a pro-inflammatory cytokine that can induce hypoglycaemia, but has also been suggested to be involved in the generation of hostility and aggression. Our group has previously shown an altered glucose metabolism in patients with self-inflicted aggressive behaviour. We investigat

Objectives Osteoarthritis (OA) is the most prevalent form of arthritis and accounts for substantial morbidity and disability, particularly in older people. It is characterised by changes in joint structure, including degeneration of the articular cartilage, and its aetiology is multifactorial with a strong postulated genetic component. Methods A meta-analysis was performed of four genome-wide asso

Popular Abstract in Swedish Avhandlingen handlar om vetenskaplig osäkerhet i policyprocessen, det vill säga när vetenskaplig kunskap om en fråga saknas eller den existerande kunskapen är osäker. Studiens huvudsyfte är att förstå om och hur vetenskaplig osäkerhet påverkar policyprocessen. För att undersöka detta har utvecklingen av den svenska klimatpolitiken från 1975 fram till 2007 studerats. MatThe dissertation is about scientific uncertainty in the policy process, that is when scientific knowledge about an issue is lacking or the existing knowledge is uncertain. The aim of the study is to understand if and how scientific uncertainty affects the policy process. For that purpose, the development of climate change policy in Sweden is studied, from 1975 until 2007. The material studied cons

In sustainability research and elsewhere the notion of resilience is attracting growing interest and causing heated debate. Those focusing on resilience often emphasize its potential to bridge, integrate, and unify disciplines. This paper attempts to evaluate these claims. Resilience is investigated as it appears in several fields, including materials science, psychology, ecology, and sustainabili

Recent findings have shown that the physiological functions of the hormone aldosterone go far beyond its well-known role in blood-pressure regulation and salt/water homeostasis. Aldosterone is for example involved in the regulation of inflammation, and also binds directly to mineralocorticoid receptors in specific brain regions. Interestingly, depressive symptoms appear to correlate with alteratio

Steep-slope devices, such as tunnel field-effect transistors (TFETs), have recently gained interest due to their potential for low power operation at room temperature. The devices are based on inter-band tunneling which could limit the on-current since the charge carriers must tunnel through a barrier to traverse the device. The InAs/GaSb heterostructure forms a broken type II band alignment wh

We have developed a method to estimate free energies of reactions in proteins, called QM/MM-PBSA. It estimates the internal energy of the reactive site by quantum mechanical (QM) calculations, whereas bonded, electrostatic, and van der Waals interactions with the surrounding protein are calculated at the molecular mechanics (MM) level. The electrostatic part of the solvation energy of the reactant

Supplemental Instruction (SI) is today a well-known academic assistance program that provides help for students in "difficult" courses. SI has repeatedly been shown to decrease the percentage of failures in the course as well as increasing course grades for students who attended SI sessions. Although SI is open for all students, its main objective is to come to terms with students' high failure ra

The key role of tropical forest belowground carbon stocks and fluxes is well recognised as one of the main components of the terrestrial ecosystem carbon cycle. This study presents the first detailed investigation of spatial and temporal patterns of fine root stocks and fluxes in tropical forests along an elevational gradient, ranging from the Peruvian Andes (3020 m) to lowland Amazonia (194 m), w

Background: Our objective was to explore outcome and clinical changes in hand function, satisfaction in daily occupations, sleep disturbances, health and quality of life in consecutive patients after a severe or major hand injury. Our objective was also to investigate possible differences between groups according to severity of injury, presence of peripheral nerve injury and the patients' sense of

A new type of electromagnetic soft magnetic material (SMM) is introduced, based on spherical iron powder particles and a suitable polymer binder. A key feature of this material is that it can be cast or molded into almost any 3D shape, hence the denotation soft magnetic moldable composite ((SMC)-C-2). The SM2C is compared with a set of reference materials, such as ferrites, laminated steels, and s

Song is a sexually selected trait in many bird species and has been suggested to function as a signal of a male's health and parasite resistance. Here we present an experimental field study on the long-term effects of parasite exposure early in life on adult bird song. We exposed nestling great tits (Parus major) to ectoparasitic hen fleas (Ceratophyllus gallinae) and on their recruitment into the

Context: During systematic literature reviews it is necessary to assess the quality of empirical papers. Current guidelines suggest that two researchers should independently apply a quality checklist and any disagreements must be resolved. However, there is little empirical evidence concerning the effectiveness of these guidelines. Aims: This paper investigates the three techniques that can be use

In this paper we discuss $(\epsilon,\delta)$-Freudenthal Kantor triple systems with certain structure on the subspace $L_{-2}$ of the corresponding standard embedding five graded Lie (super)algebra $L(\epsilon,\delta):=L_{-2}\oplus L_{-1}\oplus L_0\oplus L_1\oplus L_2; [L_i,L_j]\subseteq L_{i+j}$. We recall Lie and Jordan structures associated with $(\epsilon,\delta)$-Freudenthal Kantor triple sys
