OBJECTIVE: This study aimed to quantify the risk of COVID-19-related hospital admission in spouses living with partners in at-risk occupations in Denmark during 2020-21.METHODS: Within a registry-based cohort of all Danish employees (N=2 451 542), we identified cohabiting couples, in which at least one member (spouse) held a job that according to a job exposure matrix entailed low risk of occupati

Pelvic floor reconstructive surgery (PFRS) has suffered from high recurrence rates ever since its birth. Implants were thus quickly employed, initially autologous grafts and allografts. Technological development led to the manufacturing of synthetic implants that were believed to provide the support needed during urinary incontinence and pelvic organ prolapse (POP) surgery. However, due to a surge

We synthesized policy implications of tourism and hospitality research by reviewing 12,269 articles published in 10 leading journals from 2012 to 2021. The most common rationale for policies (i.e., the why) is market failure, while the most typical role of policies (i.e., the how) is to create incentives. In addition, policies are typically hybrid and include suggestions for formal and informal in

The bowing of the energy of the three lowest band-to-band transitions in β−(AlxGa1−x)2O3 alloys is resolved using a combined density-functional theory (DFT) and generalized spectroscopic ellipsometry approach. The DFT calculations of the electronic band structure of both β−Ga2O3 and θ−Al2O3 allow the linear portion of the energy shift in the alloys to be extracted, and provide a method for quant

We report growth optimization of Nitrogen (N)-polar GaN epitaxial layers by hot-wall metal–organic vapor phase epitaxy on 4H-SiC (000) with a misorientation angle of 4° towards the [110] direction. We find that when using a 2-step temperature process for the N-polar GaN growth, step bunching is persistent for a wide range of growth rates (7 nm/min to 49 nm/min) and V/III ratios (251 to 3774). This

Nitrogen-polar III-nitride heterostructures offer advantages over metal-polar structures in high frequency and high power applications. However, polarity control in III-nitrides is difficult to achieve as a result of unintentional polarity inversion domains (IDs). Herein, we present a comprehensive structural investigation with both atomic detail and thermodynamic analysis of the polarity evol

BACKGROUND: Elevated pulmonary vascular resistance (PVR) in the setting of left heart failure may contribute to poor outcomes after pediatric heart transplant (HTx), but peri-transplant management is variable.METHODS: We sought to characterize international practice by surveying physicians at pediatric HTx centers.RESULTS: We received 49 complete responses from 39 centers in 16 countries. Most res

Climate change is expected to alter the frequency and intensity of soil drying-rewetting (D/RW) and freezing-thawing (F/TW) events, with consequences for the activities of microorganisms. Although both D/RW and F/TW events cause respiration pulses from soil to the atmosphere, it remains unknown whether the underlying microbial control is similar. Recent work has revealed that soil microbial respon

A series of ether-free poly(p-terphenyl piperidinium)s carrying both cationic and zwitterionic groups were prepared and evaluated as anion-exchange membranes (AEMs). First, a zwitterionic monomer (zwPip) was synthesized by sulfoalkylation of N-methyl-4-piperidone (Pip) using 1,4-butane sultone. Pip and zwPip were then employed in superacid-mediated polyhydroxyalkylations with p-terphenyl to prepar

Punctuality is an important aspect of train operations, highly valued by passengers. Both Swedish and Norwegian railways have introduced frameworks to systematically improve punctuality in their systems, inspired by an extensive literature on Total Quality Management. After about a decade with these frameworks, we can see that punctuality has risen by about 2-3 percentage points. However, this pac

Due to the rise in the demand for semi-dairy beverages (vegetable fat in a de-fatted dairy matrix) as well as for fully plant-based formulations, there is a growing interest in better understanding how emulsification processes are influenced by raw material choices. Semi-dairy beverages, for example, utilize a wide variety of vegetable oils in their formulation. This contribution combines traditio

Conditions involving intracranial vascular anomalies are increasingly diagnosed, not least incidentally, with the increasing availability of neuroradiological investigations. Acute deterioration and development of symptoms due to a vascular condition could require neurosurgical intervention depending on the nature of the condition and status of the patient. On the other hand, asymptomatic patients
