This paper deals with the home-leaving of young adults in Gothenburg, Sweden, in the period 1915–1943. We used individual-level panel data from population registers and poll-tax records, taking a competing risk design for the analysis of the determinants of leaving home to marry, or for non-familial living. We found a transitional, marriage-driven pattern of leaving home that neither fits the old
Background and Objectives: Temporomandibular disorders (TMDs) is an umbrella term for pain and dysfunction involving jaw muscles and/or the temporomandibular joint, with whiplash trauma suggested to be one risk factor. The aim was to evaluate prevalence and relative risk of TMDs in the acute and chronic stages after whiplash trauma. Databases and Data Treatment: This review was registered in Prosp
The principal results of project 440 "Assembly and Breakup of Rodinia" of the International Geological Correlation Programme (IGCP) are reviewed in this work. A map of that supercontinent compiled using geological and paleomagnetic data describes global paleogeography 900 Ma ago. The assembly of Rodinia, which comprised most of Precambrian continental blocks, lasted ca. 400 m.y. (from 1300 to 900
Applications of microchannel heat sinks for dissipating heat loads have received great attention. Wavy channels are recognized to be an alternative cooling technology to enhance the heat transfer, and are successfully applied in heat exchangers. In this article, three kinds of liquid-cooling double-layer microchannel heat sinks, such as a rectangular straight microchannel heat sink, a parallel-flo
The aim of this research is evaluation of land suitability for urban land-use planning. Four factors and fourteen criteria were selected for suitability analysis and land-use planning. Factors and criteria were defined based on literature survey, experts' opinions, local contexts and availability of data. GIS-based Analytical Hierarchy Process (AHP) was used as a Multi-criteria Decision Making mod
We consider a class of external potentials on the complex plane C for which the coincidence set to the obstacle problem contains a Jordan curve in the exterior of the droplet. We refer to this curve as a spectral outpost. We study the corresponding Coulomb gas at β=2[jls-end-space/].Generalizing recent work in the radially symmetric case, we prove that the number of particles which fall near the s
Dryland ecosystems are globally important, yet state-of-the-art dynamic vegetation models often lack specific processes or parameterizations that are critical for accurately simulating dryland dynamics. These missing processes include a realistic calculation of soil water movement, detailed plant–water relations, or a representation of deep water uptake. In this study, we show how including a proc
The Intermediate Wheatgrass (IWG) Thinopyrum intermedium (Host) Barkworth & D.R. Dewey, marketed under the trade name Kernza® has been tested in France with a group of farmers since 2017. The Life Cycle Assessment (LCA) is a recognized methodology to assess the potential environmental impacts and resources consumption associated with a production system. An attributional LCA following ISO 1404
BackgroundThe use of single-use laryngeal masks has increased in recent decades; yet, their climate and environmental impacts remain poorly understood. This study aimed to compare the climate impacts of reusable and single-use laryngeal masks.MethodsWe conducted a life cycle assessment that compared the reusable Ambu Aura40 with the single-use Ambu AuraStraight and Intersurgical Igel+ laryngeal ma
Fire is a pivotal aspect of human involvement in the carbon cycle. However, the precise timing of the large-scale human fire use remains uncertain. Here, we report a pyrogenic carbon record of East Asian fire history over the past 300,000 y from the East China Sea. This record suggests a rapid increase in fire activity since approximately 50,000 y ago, indicating a decoupling from the monsoon clim
The acidobasic and complexing properties of 1-methyl-2-mercaptoimidazole (Methimazole, an anti-thyroid drug) were investigated. The pKa 11.49 ± 0.03 was estimated by molecular absorption spectroscopy (I = 0.10 M NaCl, t = 25.0 ± 0.1 °C). This value is in good agreement with the value 11.58 ± 0.05, obtained using the solvent-extraction technique. Theoretical (LFER and quantum chemical calculations)
Tropical oceans are the main global water vapor and latent heat sources, but their responses to radiative forcing remain unclear. Here, we investigate oceanic moisture dynamics of the western tropical Pacific (WTP) over the past 210,000 years through an approach of planktonic foraminiferal triple oxygen isotope (Δ′17O). The Δ′17O record is dominated by the precession cycles (~23,000 years), with l
Prostate-specific antigen (PSA) and human glandular kallikrein 1 (hGK-1) are structurally similar products of the human glandular kallikrein gene locus on chromosome 19 that become selectively expressed by human prostate tissue. PSA is one of the most abundant prostate-derived proteins in the seminal fluid. The mature form of PSA, a single-chain glycoprotein of 237 amino acids, is a serine proteas
The structural and dielectric properties of gadolinium oxide (Gd2O3) grown on Si(001) depending on the epitaxial growth conditions were investigated. Gd2O3 layers were grown at temperatures between 250 °C and 400 °C with an oxygen partial pressure between 2 x 10-7 mbar and 5 x10-7 mbar. The crystal structure of the Gd2O3 turns out to be monoclinic with rotational domains as revealed by x-ray diffr
Forests mitigate climate change by storing carbon and reducing emissions via substitution effects of wood products. Additionally, they provide many other important ecosystem services (ESs), but are vulnerable to climate change; therefore, adaptation is necessary. Climate-smart forestry combines mitigation with adaptation, whilst facilitating the provision of many ESs. This is particularly challeng
Strengthening of feed security in the Sahel is urgently needed given the climate change and growing human population. A prerequisite to this is sustainable use of rangeland forage resources for livestock. Many studies have focused on the assessment of rangeland resources during the rainy season, while only a few have focused on the dry season which is the longest and most demanding period for live
