BACKGROUND: Transmission of coronavirus disease 2019 (COVID-19) can occur through inhalation of fine droplets or aerosols containing infectious virus. The objective of this study was to identify situations, patient characteristics, environmental parameters, and aerosol-generating procedures (AGPs) associated with airborne severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus.METHODS:

Alongside established heritage institutions, family historians are central figures in the ecosystem of digital heritage, both as contributors to and users of digitized historical sources. With that in mind, this research aims for a wide examination of family historians’ engagement with the broader selection of available digital platforms, providing knowledge about how and why they choose to use on

5G cellular networks can utilize millimeter wave signals, and support large bandwidths and large antenna arrays, which provide more geometric-based signals and higher delay and angle resolutions. These merits bring new opportunities in positioning the user with limited infrastructure through the use of combined angle and delay information. However, there are many practical challenges to overcome,

Integration of emerging membrane processes [i.e., forward osmosis (FO), membrane distillation (MD), reverse electrodialysis (RED)] and mature membrane processes [i.e., reverse osmosis (RO)] can address the need for efficient desalination solutions. Utilization of different membrane units in pre- and post-treatment stages allows lowering the energy requirements and environmental impacts of the proc

T-cell lymphoma (TCL) is a rare group of malignancies and one of the important aims in this thesis has been to broaden the general knowledge of TCL with descriptive patient data. Main focus has been to examine prognosticfactors for overall survival (OS) and progression-free survival (PFS), and to evaluate different treatment approaches and follow-up (FU) after treatment.The purpose of the first st

This chapter provides an overview of the multi-faceted landscape of methods used to study the steering effects of the Sustainable Development Goals. After a discussion of the political use of science and the complex relations between science and politics, the chapter showcases a selection of different methods that are employed to trace the steering effects of the Sustainable Development Goals. Sel

This work is concerned with determining optimal sensor placements that allow for an accurate location estimate of structured signal sources, taking into account the expected location areas and the typical range of the parameters detailing the signals. In the presentation, we illustrate the technique for tonal sound signals, exploiting the expected harmonic structure of such signals. To determine p

Since the 1980s, central governments have decentralized forestry to local governments in many countries of the Global South. More recently, REDD+ has started to impact forest policy-making in these countries by providing incentives to ensure a national-level approach to reducing emissions from deforestation and forest degradation. Höhne et al. analyze to what extent central governments have rebuil

Objective: To compare the efficacy of angioplasty using drug-eluting balloons (DEB) compared with plain old balloon angioplasty (POBA) to reduce the rate of restenosis. Methods: This prospective, single-centre, single-blinded, 1:1 randomized, clinical trial enrolled patients that had primary or restenotic lesions in native upper extremity arteriovenous (AV) fistulas or at the graft-venous anastomo
