Models of stellar clusters link the theoretical gravitational N-body problem to the study of real astrophysical systems. Such models require a description of the stars contained within the cluster. Stars are interesting objects in their own right, and the study of stellar evolution is important across astronomy, from the formation of exotic objects such as X-ray binaries and gamma-ray bursts to me

OBJECTIVES: Deep bone and joint infections (DBJI) are directly intertwined with health, demographic change towards an elderly population, and wellbeing.The elderly human population is more prone to acquire infections, and the consequences such as pain, reduced quality of life, morbidity, absence from work and premature retirement due to disability place significant burdens on already strained heal

AbstractPURPOSE: To determine whether the presence of one or more cilioretinal arteries, a distinct element of the pattern of fundus vessels, is genetically programmed, influenced by environmental factors, or the result of random mechanisms of vascular development. METHODS: The fundi of 112 pairs of healthy monozygotic and dizygotic twins were examined using digital fundus photography and visual a

“Be Prepared!” The motto of the Scout movement seemed fitting when the Second World War broke out in 1939. Sweden maintained a state of neutrality during the entire conflict but this period, known generally as the “Time of Preparedness” (beredskapstiden), affected all parts of society. While the diplomatic and political events of these years have been thoroughly covered in Swedish historiography,

Validated planet candidates need not lie on long-term stable orbits, and instability triggered by post-main-sequence stellar evolution can generate architectures which transport rocky material to white dwarfs, hence polluting them. The giant planet HD 131399Ab orbits its parent A star at a projected separation of about 50-100 au. The host star, HD 131399A, is part of a hierarchical triple with HD

This paper contributes to understanding national variations in using low-carbon electricity sources by comparing the evolution of nuclear, wind and solar power in Germany and Japan. It develops and applies a framework for analyzing low-carbon electricity transitions based on interplay of techno-economic, political and socio-technical processes. We explain why in the 1970s–1980s, the energy paths o

Solar energy is considered to be an alternative sustainable energy source in the urban environment. The potential of using solar energy in urban areas is highly dependent on urban morphology which affects the level of solar irradiance received by individual buildings. Many studies focus on solar energy potential of building form in urban areas but relatively few studies examine how urban morpholog

During the 1970s, pornographic magazines that envisioned the Finnish man sovereignly enjoying sexual pleasures in Eastern Europe, the Soviet Union, the Middle East, and the Far East became extremely popular in Finland. In this article it is argued that pornographic magazines functioned as geographical as well as sexual maps; through the medium of magazines, Finnish readers were educated to think o

Objective: To describe the anatomy of uterine lymphatic drainage following cervical or fundal tracer injection to enable standardization of a pelvic sentinel lymph node (SLN) concept in endometrial cancer (EC). Methods: A prospective consecutive study of women with EC was conducted. A fluorescent dye (Indocyanine green) was injected into the cervix (n = 60) or the uterine fundus (n = 30). A system

We reanalyze the recent multilab preregistered study on ego-depletion by Hagger and Chatzisarantis (2016) as if their data were obtained under the research program-strategy (Witte & Zenker, 2016a, 2016b). This strengthens Hagger and Chatzisarantis’s (2016) main conclusion, because our reanalysis more directly corroborates the absence of a medium-sized, or a small-sized, ego-depletion effect (d

The entrepreneurial ecosystem (EE) literature has attracted much attention, especially in policy circles. However, the concept suffers from a number of shortcomings: (1) it lacks a clear analytical framework that makes explicit what is cause and what is effect in an EE; (2) while being a systemic concept, the EE has not yet fully exploited insights from network theory, and it is not always clear i

A swirl stabilized gas turbine burner has been simulated in order to assess the effects of the fuel properties on spray dispersion and fuel-air mixing. The properties under consideration include fuel surface tension, viscosity and density. The turbulence of the gas phase is modeled applying the methodology of large eddy simulation whereas the dispersed liquid phase is described by Lagrangian parti

Objective: To explore the association between administration-to-birth interval of antenatal corticosteroids (ACS) and survival in extremely preterm infants. Design: Population-based prospective cohort study. Setting: All obstetric and neonatal units in Sweden from 1 April 2004 to 31 March 2007. Population: All live-born infants (n = 707) born at 22-26 completed weeks of gestation. Methods: The rel

Rare cells in blood, such as circulating tumor cells or fetal cells in the maternal circulation, posses a great prognostic or diagnostic value, or for the development of personalized medicine, where the study of rare cells could provide information to more specifically targeted treatments. When conventional cell separation methods, such as flow cytometry or magnetic activated cell sorting, have fa

Heavy-metal homeostasis and detoxification is crucial for cell viability. P-type ATPases of the class IB (PIB) are essential in these processes, actively extruding heavy metals from the cytoplasm of cells. Here we present the structure of a PIB-ATPase, a Legionella pneumophila CopA Cu(+)-ATPase, in a copper-free form, as determined by X-ray crystallography at 3.2 Å resolution. The structure indica
