Nests are structures built to support and protect eggs and/or offspring from predators, parasites, and adverse weather conditions. Nests are mainly constructed prior to egg laying, meaning that parent birds must make decisions about nest site choice and nest building behavior before the start of egg-laying. Parent birds should be selected to choose nest sites and to build optimally sized nests, ye
Introduction Given the safety issues of nonsteroidal anti-inflammatory drugs (NSAID) and the robustness of guidelines, making treatment choices in daily clinical practice is increasingly difficult. This study aimed systematically to analyse the opinions of a multidisciplinary European expert panel on the appropriateness of different NSAID, with or without the use of a proton pump inhibitor (PPI),
Through an agreement with EEE producers, Swedish municipalities are responsible for collection of hazardous waste and waste electrical and electronic equipment (WEEE). In most Swedish municipalities, collection of these waste fractions is concentrated to waste recycling centres where households can source-separate and deposit hazardous waste and WEEE free of charge. However, the centres are often
Building on a framework introduced by Chaney and Ossa (2013), we construct a task-based model of the firm’s choice of occupational inputs to examine how that choice varies with greater global engagement. We depart from Chaney and Ossa by assuming that more complex tasks are more costly to complete. Within the structure of our model, firms skew employment toward occupations engaged in more complex
En ökning av skador på kalla ventilerade vindar orsakade av kondensproblem har iakttagits. En ökad isolering i vindsbjälklaget i kombination med att skorstensstocken numera är kall, eller saknas helt, har bidragit till att vindsutrymmet blivit kallare. Med skorsten säkerställdes alltid ett undertryck i hela byggnaden samt en bättre luftomsättning under uppvärmningssäsongen. Utan skorsten får vi fö
Feather mosses utilize various sources of nitrogen (N): they absorb N deposited on leaf tissue, they host N-2 fixing cyanobacteria, and they are able to take up N directly from soil. In addition to their importance as primary producers in boreal ecosystems, feather mosses play a significant role in N cycling. However, estimates of their ability to take up N from soil in situ are scarce. Further, c
This article concerns itself with the early twentieth-century documentation of different phenomena in the Swedish countryside considered crucial to an understanding of rural lifestyle in the past. This research was motivated out of a concern for a vanishing peasant culture. Vast quantities of photographs, drawings and descriptions of houses and settlements were compiled into archives and later on,
This is a study of wool in Icelandic history in a broad context, whereby wool production serves as a channel to central aspects of 18th-century society. The objective is to explore ideas about Iceland’s economy that were current in the 18th century in the light of developments in Denmark at the time, to place these ideas in the context of the recent introduction of workshopmanufacturing to Iceland
Safe coexistence of industrial robots and human operators in the same workspace is one of the long standing goals of robotics research. One way to enforce safety is to endow the robotic system with additional sensors that can to some extent monitor the environment surrounding the robot and allow fast reaction to unexpected obstacles. This paper discusses the design of one such anti-collision syste
Abstract in Norwegian Det østkirkelige vigselsritualet presenteres med vekt på tekstenes tilknytning til fortellingen i Joh 2,1-11 og andre bibelske ekteskap: Hvordan etablerer ritualet det nye paret som et par i Guds frelseshistorie?
Obesity is a well-established risk factor for colorectal cancer (CRC), and accumulating evidence suggests a differential influence of sex and anthropometric factors on the molecular carcinogenesis of the disease. The aim of the present study was to investigate the relationship between height, weight, bodyfat percentage, waist- and hip circumference, waist-hip ratio (WHR), body mass index (BMI) and
Context: Late-onset hypogonadism (LOH) has recently been defined as a syndrome in middle-aged and elderly men reporting sexual symptoms in the presence of low T. The natural history of LOH, especially its relationship to mortality, is currently unknown. Objective: The aim of this study was to clarify the associations between LOH, low T, and sexual symptoms with mortality in men. Design, Setting, a
We have recently reported Monte Carlo simulations for a system of two infinite like-charged plates in a dipolar fluid solvent (Pegado et al 2008 J. Chem. Phys. at press). The pressure as a function of plate separation qualitatively reproduces the ion-ion correlation attraction picture seen in primitive model studies, where the solvent only enters the picture implicitly through its dielectric const
P>Overactivity of striatal alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) glutamate receptors is implicated in the pathophysiology of l-DOPA-induced dyskinesia (LID) in Parkinson's disease (PD). In this study, we evaluated the behavioural and molecular effects of acute and chronic blockade of Ca2+-permeable AMPA receptors in animal models of PD and LID. The acute effects of the Ca
Here we present the first four dimensional (time and three dimensional space resolved) experiment on a strongly deformed geological material. Results show that even complicated microstructures with large continuous and discontinuous changes in crystallographic orientation can be resolved quantitatively. The details that can be resolved are unprecedented and therefore the presented technique promis
We outline a descriptive framework of how candidate alleles of the immune system associate with infectious diseases in natural populations of animals. Three kinds of alleles can be separated when both prevalence of infection and infection intensity are measured-qualitative disease resistance, quantitative disease resistance and susceptibility alleles. Our descriptive framework demonstrates why all
