Vacuum cleaner motor is an air cooled single-phase induction motor with impeller. Its compact design can result in more than 2 kW of input power per 1 kg of mass. It can operate only if an air flow is cooling the motor; otherwise it is overheated and destroyed. A large production volume of a vacuum cleaner motor classifies it as a mass production product. In the past its development has been mostl
Extracellular histones are present in the airways because of cell death occurring during inflammation. They promote inflammation and cause tissue damage due to their cationic nature. The anionic phosphoglycoprotein osteopontin (OPN) is expressed at high levels during airway inflammation and has been ascribed both pro- and anti-inflammatory roles. In this study, it was hypothesized that OPN may neu
The overall kinetics for manganese(II/III) catalyzed autoxidation of dissolved sulfur dioxide has been studied by UV-vis spectrophotometry. A free-radical mechanism has been proposed, and the rate constant for one of the key reactions between manganese(II) and peroxomonosulfate has been determined by pulse radiolysis. Previous literature on manganese catalyzed autoxidation of SO2(aq) has been thor
With the construction sector being responsible for about 40% of the energy and material use, the sector has a great responsibility for lowering the consumption if we are to succeed in our global pursuit for the green transition. However, buildings must still comply with the demands of users. For long-span, openspace lightweight, multi-storey buildings, this provides a potential risk related to ann
As part of the green transition, a current trend in the construction sector is to utilize more wood and lightweight composites, aiming at a reduction of the embodied energy in buildings. At the same time, with a focus on circularity and reuse, large-span structures are preferable, since they provide more flexibility for future uses of the building. The mix of large spans and lightweight structures
Timber buildings are intrinsically lightweight and hence can be susceptible to low-frequency vibrations and structure-borne noise. So, within the development of technical solutions for mitigating unwanted vibrations and noise, accurate and computationally efficient numerical models are considered to be of great value. Such models should take into account all physical phenomena that are relevant fo
In this study, vegetation optical depth from ESA's Soil Moisture and Ocean Salinity (SMOS) satellite mission is combined with other existing remote sensing, meteorological and literature data in order to obtain values of gravimetric vegetation water content (Mg). The methodology combines an effective medium model valid at passive microwave frequencies with a vegetation dielectric constant model. T
The use of wood as load-bearing material in residential and office buildings has increased significantly in Europe over the last decades. Such buildings often have wooden floors built with boards supported by joists and/or beams. The modal properties of such floors are important regarding the floors’ dynamic response to walking and other usage as well as structure-borne vibration and re-radiated n
Event detection and classification algorithms are resilient towards aggressive resource-aware optimisations. In this paper, we leverage this characteristic in the context of smart health monitoring systems. In more detail, we study the attainable benefits resulting from tailoring Support Vector Machine (SVM) inference engines devoted to the detection of epileptic seizures from ECG-derived features
Background: Methyl mercury (MeHg) is a well-known neurotoxin and evidence suggests that also low level exposure may affect prenatal neurodevelopment. Uncertainty exists as to whether the maternal MeHg burden in Norway might affect child neurodevelopment. Objective: To evaluate the association between prenatal mercury exposure, maternal seafood consumption and child language and communication skill

Bridges are an important part of the traffic infrastructure, which are subjected to high safety requirements and economic consequences in case of functionality failure. Therefore, it is needed to consider potentially substantial direct and indirect risks during service life, i.e., the need for risk and robustness analyses. Over the last decades, various quantitative performance criteria have been
The manual execution of failure mode and effects analysis (FMEA) is time-consuming and error-prone. This article presents an approach in which large language models (LLMs) are integrated into FMEA. LLMs improve and accelerate FMEA with human in the loop. The discussion looks at software tools for FMEA and emphasizes that the tools must be tailored to the needs of the company. Our framework combine
OBJECTIVES: To evaluate if ileo-psoas muscle size and visceral adipose tissue (VAT) can predict long-term survival after endovascular aneurysm repair (EVAR). METHODS: Patients who underwent EVAR between 2004 and 2012 in a single centre were included. Total psoas muscle area (TPA), abdominal VAT area, subcutaneous adipose tissue (SAT), and total adipose tissue were measured on the preoperative CT.
Objectives This study aims to investigate (1) the microbial community composition by work characteristics and (2) the association between microbial genera level and inflammatory markers among recycling workers. Methods In this cross-sectional study, inhalable dust was collected with personal samplers from 49 production (86 samples) and 10 administrative workers (15 samples). Four groups of micro-o
BACKGROUND: Hounsfield unit (HU) measurement obtained from computed tomography (CT) scans of the wrist is a potential new screening method for low bone mineral density (BMD). We hypothesized that HU measurements of the ulnar head obtained from CT scans would correlate with BMD assessed with dual x-ray absorptiometry (DXA) scans of the forearm.METHODS: Patients with both upper-extremity CT and DXA
This chapter presents the long-term clinical outcomes and prognosis of COVID-19. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has triggered a global pandemic infecting over 773 million people and causing over seven million deaths worldwide as of December 2023 (WHO Coronavirus). Despite the United Nations proclaimed the coronavirus disease 19 (COVID-19) pandemic officially over on M
