Copper permalloys for fluxgate magnetometer sensors
Authors: Narod B. Barry , Miles David M. 
Published: June 2024

Abstract. Fluxgate magnetometers are commonly used to provide high-fidelity vector magnetic field measurements. The magnetic noise of the measurement is typically dominated by that intrinsic to a ferromagnetic core used to modulate (gate) the local field as part of the fluxgate sensing mechanism. A polycrystalline molybdenum–nickel–iron alloy (6.0–81.3 Mo permalloy) has been used in fluxgates since the 1970s for its low magnetic noise. Guided by previous investigations of high-permeability copper–nickel–iron alloys, we investigate alternative materials for fluxgate sensing by examining the magnetic properties and fluxgate performance of that permalloy regime in the range 28 %–45 % Cu by weight. Optimizing the alloy constituents within this regime enables us to create fluxgate cores with both lower noise and lower power consumption than equivalent cores based on the traditional molybdenum alloy. Racetrack geometry cores using six layers of ∼30 mm long foil washers consistently yield magnetic noise around 4–5 pT/Hz at 1 Hz and 6–7 pT/Hz at 0.1 Hz, meeting the 2012 1 s INTERMAGNET standard of less than 10 pT/Hz noise at 0.1 Hz.

OBJECTIVES: Several studies have found higher sickness absence in shared and open workspaces than in private offices, but little is known about why these differences occur. We propose and test job control as a potential mechanism underlying observed differences in the risk of physician-certified sickness absence between private offices and shared and open workspaces.
METHODS: We conducted a counterfactual mediation analysis using observational survey data from a nationally representative sample of Norwegian employees merged with prospective data from national registries (N=5512). The registry data included information about whether participants had any physician-certified sickness absence the year following the survey. Models were adjusted for age, sex, education level, occupation group, executive/leadership responsibility, and time spent on office work.
RESULTS: We found significantly higher sickness absence risk in conventional [risk ratio (RR) 1.12, 95% confidence interval (CI) 1.01‒1.25] and non-territorial (RR 1.20, 95% 1.04‒1.37) open-plan and non-territorial shared-room offices (RR 1.29, 95% CI 1.13‒1.48) compared to private offices. Natural indirect effects due to job control were statistically significant in all contrasts and accounted for 19–34% of total effects depending on contrast.
CONCLUSIONS: Findings were in line with hypothesized relationships and suggest that job control may be a mechanism underlying observed differences in sickness absence across office concepts. Future studies should continue to explore potential mechanisms linking shared and open workspaces to higher sickness absence and other unfavorable outcomes in the workplace, particularly with study designs that provide stronger basis for causal inference.
Does job stress mediate the risk of work disability due to common mental disorders among social workers compared with other health and social care, education, and non-human service professionals? A prospective cohort study of public sector employees in Finland

OBJECTIVE: This study aimed to investigate (i) the risk of work disability (>10-day sickness absence spell or disability pension) due to common mental disorders (CMD) among social workers compared with other health and social care, education, and non-human service professionals and (ii) whether the risk was mediated by job stress.
METHODS: A cohort of 16 306 public sector professionals in Finland was followed using survey data from baseline (2004 or if not available, 2008) on job stress [job strain or effort-reward imbalance (ERI)] and register data on work disability due to CMD from baseline through 2011. A Cox proportional hazards model was used to analyze the risk of work disability due to CMD between three occupation-pairs in a counterfactual setting, controlling for age, sex, job contract, body mass index, alcohol risk use, smoking, and physical inactivity.
RESULTS: Social workers’ job stress was at higher level only when compared to education professionals. Thus, the mediation hypothesis was analyzed comparing social workers to education professionals. Social workers had a higher risk of work disability due to CMD compared with education professionals [hazard ratio (HR) 2.08, 95% confidence interval (CI) 1.58–2.74]. This HR was partly mediated by job strain (24%) and ERI (12%). Social workers had a higher risk of work disability than non-human service professionals (HR 1.54, 95% CI 1.13–2.09), but not compared with other health and social care professionals.
CONCLUSIONS: Job stress partly mediated the excess risk of work disability among social workers only in comparison with education professionals.

Abstract: Studying synthetic fuels is imperative due to their potential to offer sustainable alternatives to conventional fossil fuels, thereby addressing environmental concerns, enhancing energy security, and facilitating the transition to cleaner and more efficient transportation systems. This study presents an experiment analysis concentrating on spray characteristics of five types of synthetic fuels (bio-naphtha, EtG, G40, bio-ethanol, and DMC) in a comparison with gasoline. The experiment was conducted ranging from non-evaporated conditions to evaporated conditions, to thoroughly assess the spray behavior of the tested fuels. Results showed that EtG and G40 share similar properties with conventional gasoline. The discharge coefficient (Cd) was found to increase closely linearly with the square root of fuel density. Under non-evaporated condition (Ta = 25 °C), except for DMC, the spray tip penetration of other fuels deviates within ±5% compared to gasoline. Under evaporated condition (Ta = 200 °C), EtG maintains a spray tip penetration within ±5% of gasoline, while bio-naphtha, G40, and DMC fall within ±10% of gasoline. Notably, bio-ethanol shows a 12% higher penetration compared to gasoline, likely due to its slower evaporation and higher latent heat of vaporization.

De Patiëntenrichtlijn en het Nederlandse zorgverzekeringsstelsel: het einde van de discussie over het hinderpaalcriterium?
Op 10 november 2023 sprak de Hoge Raad zich uit over de vraag of de Nederlandse vergoedingsregels voor de kosten van gezondheidszorg, en het zogenoemde ‘hinderpaalcriterium’ in het bijzonder, in overeenstemming zijn met de in 2011 aangenomen Patiëntenrichtlijn. De discussie over deze vraag speelt al langere tijd. Vóór het arrest van de Hoge Raad hadden meerdere auteurs zich al uitgelaten over deze vraag. Zij waren nagenoeg unaniem van mening dat het hinderpaalcriterium niet door de EU-rechtelijke beugel kan. De Hoge Raad kwam echter tot de conclusie dat de Nederlandse regels, in ieder geval in de onderhavige zaak, wel aan de eisen van de Patiëntenrichtlijn voldoen en zag geen noodzaak om prejudiciële vragen aan het Hof van Justitie te stellen. Deze bijdrage analyseert het arrest van de Hoge Raad en laat zien dat het arrest de spanning tussen het Nederlandse stelsel en het EU-recht niet weg heeft genomen. Verwijzing naar het Hof van Justitie was wel degelijk wenselijk geweest.

Relevance. In the realm of elite sports, the necessity for a straightforward, lucid, and dependable assessment of adaptive resources and mechanisms cannot be overstated. Given the prevalence of near maximum loads in athletic endeavors, there exists a propensity for athletes to teeter on the brink of overtraining. The body, being a single whole, responds to any impact, including physical activity, with a set of changes in its indicators. Fundamental research in the field of sports biochemistry carried out in recent decades, and, in particular, on changes in carbohydrate, fat, and protein metabolism under the influence of various sports activities, has made it possible to widely use the parameters of energy metabolism in sports practice. Lactate analysis is a reliable tool for monitoring the training process since changes in lactate levels reflect the intensity of physical activity and the body's adaptation to stress.The purpose of the study was to study the lactate content in the blood of highly qualified football players in the pre-competitive period. The work consists of optimizing the training process to achieve high results in competitions.Methods. The content of lactate in the blood of highly qualified football players in the pre-competition period is being studied, which indicates the importance of this parameter in assessing their physical fitness before competitions. Lactate analysis is an important part of monitoring the training process and allows you to optimize it to achieve the highest results in competitions. To conduct blood lactate testing, a portable lactate analyzer Lactate Plus (Sports) was used.Conclusions. Optimization of the training process provides coaches and medical personnel with information about the reaction of football player's bodies to training loads in the pre-competition period and helps adapt training programs to the individual needs of each athlete.

Published: June 2024

Relevance: Researchers have shown that the characteristics of postural control in open-eyed children with visual impairment were higher than in sighted children, and these data are also associated with physical activity in their free time and the age at which they started playing sports. It is possible that people with visual or hearing impairments are more effective at maintaining balance, which may explain why they achieve similar or better results in posture control tasks compared to their normally developed peers.The aim of the study is to study the features of the statokinetic stability of athletes of three nosological groups: with hearing impairment, with visual impairment and with intellectual disabilities.Methods and organization of research. The method of stabilometry was used: the ST-150 stability platform and the STPL program. The area of the statokinesiogram (S, mm2); the average velocity of displacement of the pressure center (V, mm/s) and the energy consumption coefficient (Ke, conl. units) were studied.The results of the study and their discussion. When analyzing intra-group changes in athletes with hearing impairment, a significant deterioration in the function of static equilibrium was found in the test with closed eyes, which is typical for athletes with intellectual disabilities, but the results in the test with open eyes in these athletes are significantly better than in athletes with hearing impairment. Athletes with hearing impairment and athletes with intellectual disabilities have a pronounced forward asymmetry. In the sagittal plane, athletes with visual impairment have a pronounced asymmetry to the left. Normally balanced control revailed among athletes with hearing impairment. Normally balanced and proprioceptive control was revealed in athletes with visual impairment. Visual control prevailed among athletes with intellectual disabilities. The best statistical stability was revealed in athletes with intellectual disabilities, compared with athletes of the studied nosologies.Conclusions. Thus, the features of the statokinetic stability of athletes with hearing impairment, visual impairment and intellectual disabilities were revealed.

Published: June 2024

Background: Pulmonary fibrosis is a chronic, progressive lung condition that involves lung tissue scarring and thickening. The effects of home-based pulmonary rehabilitation (PR) in post-covid pulmonary fibrosis (PCPF) and other forms of fibrosis together have not been evaluated. This study aims to evaluate the effectiveness of home-based pulmonary rehabilitation on pulmonary function, functional capacity, and health-related quality of life in people with pulmonary fibrosis (post-COVID pulmonary fibrosis, pulmonary fibrosis secondary to pulmonary tuberculosis (TB), pulmonary fibrosis secondary to interstitial lung disease (ILD), pulmonary fibrosis secondary to bronchiectasis). Methods: A single-group pretest–posttest experimental study was performed after recruiting 98 pulmonary fibrosis subjects from K.M.C hospitals. After being screened for the inclusion and exclusion criteria, 45 subjects were analyzed, and 6 subjects were lost to follow-up. A home-based pulmonary rehabilitation program was carried out for 8 weeks (warm-up, stretching exercises, aerobic exercise, strength training for upper limb and lower limb, breathing exercises mainly involved; others: energy saving techniques, controlled coughing techniques, dyspnea relieving positions). The program was supervised via weekly phone calls. Pulmonary function (Pulmonary function test), exercise capacity (6-minute walk test), dyspnea (modified Borg scale), and health-related quality of life (SF-36) were evaluated before and after the intervention. During the enrollment and after the 6-minute walk test, saturation of peripheral oxygen (SPO2) level was also evaluated pre-intervention and after the 8-weeks program. Results: Pulmonary function [FVC(L) t = -12.52, p<0.05; FEV1(L) t = -2.56, p<0.05; FEV1/FVC t = 7.98, p<0.05 and DLCO (ml/min/mmHg) t = -5.13, p<0.05], 6MWD [MD 88.66; p<0.05] and HRQOL measured by SF-36 scores (p<0.05) were improved significantly. Both the baseline SPO2 level before the 6MWT [MD 1.07, p<0.05] and the SPO2 level after the 6MWT [MD 1.16, p<0.05] showed a significant improvement. The rating of perceived exertion(dyspnea) [MD 1.30, p<0.05] was reduced significantly after the 8-week program. Conclusion: Our study shows that home-based pulmonary rehabilitation is an effective option for improving lung function and physical functional capacity by reducing dyspnea perception and improving the saturation of peripheral oxygen (SPO2) level, and enhancing the quality of life in people with pulmonary fibrosis.
