Taking off from Natural Resources? Fiscal dependence in Andean and Nordic countries, 1850s-1930s

Natural resources can have a powerful impact on the public budget but may also hinder the development of other sources of revenue, thus limiting the long-term development of fiscal capacity in resource-rich countries. This article evaluates both possible effects bycomparing the long-term evolution (1850s-1930s) of public revenues in Andean (Bolivia,Chile and Peru) and Nordic (Norway and Sweden) co

Mapping of domestic hot water circulation losses in buildings – results from 134 measurements

The hot water circulation system in a building is a system which helps prevent Legionella problems whilst ensuring that tenants have access to hot water quickly. Poorly designed or implemented systems not only increase the risk to people’s health and thermal comfort, but even result in an increase in the energy needed for this system to function properly. Results from previous studies showed that The hot water circulation system in a building is a system which helps prevent Legionella problems whilst ensuring that tenants have access to hot water quickly.

Thermodynamic modelling of composition and crystal structure of ternary nanowires

An analytic expression for the composition of a ternary solid material nucleating from a quaternary liquid melt has been derived. This theory has been applied to Au-catalyzed and self-catalyzed, nucleation limited VLS growth of ternary III-V nanowires. Next, the developed model has been applied for the description of the composition dependence of the ZB/WZ polytypism in ternary nanowires.

Characterization and modeling of acousto-optic signal strengths in highly scattering media

Ultrasound optical tomography (UOT) is an imaging technique based on the acousto-optic effect that can perform optical imaging with ultrasound resolution inside turbid media, and is thus interesting for biomedical applications, e.g. for assessing tissue blood oxygenation. In this paper, we present near background free measurements of UOT signal strengths using slow light filter signal detection. W

Assembly mechanisms of the bacterial cytoskeletal protein FilP

Despite low-sequence homology, the intermediate filament (IF)-like protein FilP from Streptomyces coelicolor displays structural and biochemical similarities to the metazoan nuclear IF lamin. FilP, like IF proteins, is composed of central coiled-coil domains interrupted by short linkers and flanked by head and tail domains. FilP polymerizes into repetitive filament bundles with paracrystalline pro

Tailored emission to boost open-circuit voltage in solar cells

Recently, a lot of research focus has been on how to make solar cells more efficient. One direction is to enhance the open-circuit voltage Voc by optimizing the emission of photons in the cell, where emission is a necessary loss process due to the reciprocity between absorption and emission of light. Here, we performed a Shockley-Queisser detailed balance analysis to predict the benefit of managin

Self-adaptation of software using automatically generated control-theoretical solutions

Control theory has contributed a set of foundational techniques to handle "change" at runtime in software applications. These techniques however have fundamental limitations as well: (i) they require the development and understanding of mathematical models; (ii) synthesizing solutions is often done on a per-problem basis, discouraging flexibility and generality. Software engineering, as a discipli

Ny dynastisk historia

Är det möjligt att diskutera ett nytt forskningsfält som heter ”ny dynastisk historia”? Fanns det då något som vi brukade benämna ”gammal dynastisk historia”? Detta bidrag hävdar att en ny dynastiska historia faktiskt finns – ett fält som har vuxit ut ur många andra fält, såsom statsbildningshistoria, hovstudier, adelsstudier, kvinnohistoria, familjehistoria med mera. Nya insikter om alla dessa fä

The Emergence of Hypervirulent M1T1 Clone of Group A Streptococcus via Genetic Recombination and Host Selection

Streptococcus pyogenes (Group A Streptococcus, GAS) is a strictly human bacterial pathogen. Since the mid-1980s, GAS M1T1 clone has been the most prevalent and globally disseminated serotype and is the culprit causing invasive and severe streptococcal infections, urging a better understanding of the emergence of hypervirulent M1T1 clone from an evolutionary perspective. This review highlights the

Education, Home Exercise, and Supervised Exercise for People With Hip and Knee Osteoarthritis As Part of a Nationwide Implementation Program : Data From the Better Management of Patients With Osteoarthritis Registry

Objective: To compare the effectiveness of education (ED) plus home exercise (HE) and ED plus supervised exercise (SE) according to information provided by the Better Management of Patients With Osteoarthritis (BOA) Registry, a nationally implemented rehabilitation program for patients with hip and knee osteoarthritis (OA). In addition, we investigated whether or not the effect of the treatments d

Confident millennials : Differences in consumer confidence across five generations

This paper investigates if individuals experiencing different socio-economic environments during their formative years have different expectations about future economic conditions. We use Swedish survey data to analyse differences in expectations across five generations of consumers by testing if they have different levels of confidence. The paper focuses on all the different generations of the 19

Identity, Image and Brand

This chapter highlights how organizational images and efforts to manage those images through branding influence the identities of individuals within organizations. The authors discuss the ways in which individuals’ identity projects are regulated, challenged, or supported by images and brands. They argue that identity is a particularly important concept for understanding organizing in today’s ‘bra

From carbohydrates to fat : Trends in food intake among Swedish nutrition students from 2002 to 2017

Earlier studies have implied a change in dietary habits of the Swedish population towards a low carbohydrate, high fat diet. Questions have been raised about the development in recent years and potential health effects. We have investigated the dietary intake of Swedish female students enrolled in a university nutrition course between 2002 and 2017. The students carried out self-reporting of all f

A meta-analysis of the efficacy of HAART on HIV transmission and its impact on sexual risk behaviours among men who have sex with men

Evidence showed preventive impacts of the highly active antiretroviral therapy (HAART) on the Human Immunodeficiency Virus (HIV) transmission amomg heterosexual population, however, that is of deficit among men who have sex with men (MSM). The aim was to systematically examine the efficacy of HAART on HIV transmission and the association between the HAART initiation and unprotected anal intercours
