In the present study the thermo-hydraulic characteristics of geyser in the cryogenic fuel transportation pipe of a liquid rocket is experimentally investigated using liquid nitrogen. The typical thermo-hydraulic appearances are characterized and analyzed in the geyser process to effectively recognize the occurrence of geyser in practical engineering. The effect of interfering factors such as heat

Byggnaders energieffektivitet är ett fokusområde i arbetet med att minska klimatförändringarna, då byggnader står för cirka 40 procent av den totala energianvändningen i Europeiska unionen. En lösning som tillämpas för att minska byggnaders energibehov är att ständigt införa strängare byggregler. Följaktligen ökar betydelsen av precisa och effektiva simuleringar för att kunna beräkna byggnaders frAs most countries worldwide continue to mitigate climate change, one area of focus is a building's energy efficiency. Buildings currently account for approximately 40 per cent of the total energy use in the European Union. One solution for reducing the energy demand from buildings is by continually implementing more stringent building regulations. Consequently, the importance of accurate and effic

Archaeological radiocarbon dating in coastal northern Hokkaido is challenged by the marine reservoir effect and the scarcity of materials with terrestrial carbon sources. This has contributed to gaps and general uncertainty in the timing of the region's culture-historical periods. The Late Holocene site of Hamanaka 2 on Rebun Island, featuring a stratified shell midden context with excellent prese

Data paper. How are particular material culture traditions passed from one generation to the next? This digital archive supports "Technology as Human Social Tradition: Cultural Transmission among Hunter-Gatherers" (Jordan 2015) published by University of California Press. The archive consists of 15 Excel files which were used to conduct in-depth analysis of the factors driving diversity and change

Determining the proportion of males and females in zooarchaeological assemblages can be used to reconstruct the diversity and severity of past anthropogenic impacts on animal populations, and can also provide valuable biological insights into past animal life-histories, behaviour and demography, including the effects of environmental change. However, such inferences have often not been possible du

We explore peoples' dispositions and practices with regard to social–ecological transformations based on a sustainable welfare policy strategy in Sweden. We draw on Bourdieu's concept of habitus to highlight the relations between social positions, dispositions, and position-takings. Using data from an own survey, we identify habitus types and place these in the space of social positions. We apply

This ethnographic dataset provides a trait-based survey of variability in traditional clothing and footwear among seven Northern Khanty communities living in the Lower Ob' region of Northwestern Siberia. The data were originally gathered by A.M. Siazi and published in Russian (2000). The information was then translated and converted into the current binary dataset which records the presence/absenc

The goal of this contribution is to stimulate a wider reflection on the role of food consumption practices throughout prehistory. We focussed on the Jōmon communities of Hokkaidō Island in Northern Japan since these mobile foragers underwent a process of economic diversification and intensification, eventually leading to higher levels of sedentism across the Pleistocene-Holocene transition.

Background: The literature concerning research methodologies and methods has increased in software engineering in the last decade. However, there is limited guidance on selecting an appropriate research methodology for a given research study or project.Objective: Based on a selection of research methodologies suitable for software engineering research in collaboration between industry and academia

Background: The socio-technical characteristic of software engineering is acknowledged by many, while the technical side still dominates research. As software engineering is a human-intensive activity, the cognitive side of software engineering needs more exploration when trying to improve its efficiency.Aim: The aim of this study is to increase the understanding of the impact of cognitive load in

The crystal structures of domain-swapped tryptophan repressor (TrpR) variant Val58Ile before and after soaking with the physiological ligand l-tryptophan (l-Trp) indicate that l-Trp occupies the same location in the domain-swapped form as in native dimeric TrpR and makes equivalent residue contacts. This result is unexpected because the ligand binding-site residues arise from three separate polype

Falls are common among persons with late effects of polio (LEoP), which may lead to fear of falling and activity avoidance in everyday life. Here, we assessed the occurrence of fall-related activity avoidance among persons with LEoP and explored how these experiences influenced daily life. Fourteen ambulatory persons (seven women; mean age 70 years) with LEoP participated. They responded to the mo

The aim of this study was to explore how general practitioners cope with the challenges they face when trying to provide effective interventions to pain patients within the organizational context of a health center. Based on interviews with 15 Swedish providers, the study suggests that the challenges that general practitioners experience in the consultations with patients must be understood in a tThe aim of this study was to explore how general practitioners cope with the challenges they face when trying to provide effective interventions to pain patients within the organizational context of a health center.

Från politiskt håll finns idag en tydlig politisk intention att studenter med funktionshinder ska inkluderas i högskolornas och universitetens utbildningar. Denna artikel tar upp vad som hindrar respektive möjliggör att dessa politiska intentioner om tillgänglighet och mångfald implementeras i undervisningen. Analysen baseras på en fallstudie av en samhällsvetenskaplig institution vid ett svenskt

Artikeln berör problematiken om hur tjänstemän reagerar på förändringar i sin yrkesroll. Som specifikt fall används kampen mot ohälsan och Försäkringskassans handläggare. Författaren, Stina Hall, är doktorand vid Lunds universitet i ämnet statsvetenskap. Studien som redovisas är en del av ett större projekt om tjänstemannaroller i förändring.

Background: To demonstrate extended protection against meningococcal serogroup B (MenB) disease after MenB-FHbp (bivalent rLP2086) vaccination, this study evaluated immunopersistence through 26 months following MenB-FHbp boosting after 2 or 3 primary doses in adolescents. Study design: This phase 3, open-label study was an extension of 3 phase 2 studies with participants aged 11–18 years randomize

Background: Group B Streptococcus (GBS) is the leading cause of life-threatening infections in new-borns and may cause invasive disease, stillbirth and preterm delivery during pregnancy. While no licensed vaccine exists, maternal immunization might protect against neonatal disease and adverse pregnancy outcomes. We assessed the safety and immunogenicity of a prototype vaccine consisting of the fus
