6%, 77.2%, and 81.8% at channel-, segment-, and EEG-level. The channel- and segment-level performance is comparable to the intra-rater agreement (IRA) of an expert of 72.4% and 82%. The DLDS can process a 30 min EEG in 4 s and can be deployed to assist clinicians in interpreting EEGs.Oil spills in aquatic ecosystems cause irreparable damage to marine life and the coastal populations of affected areas. In recent years, chemical dispersants have been extensively used to remedy these impacted ecosystems, although these agents have been increasingly restricted due to their toxic potential. In this context, biosurfactants are emerging as a promising alternative to chemical dispersants, which have some advantages including low toxicity, high biodegradability and good ecological acceptability. Thus, this study aimed to the production of biosurfactant by the bacteria Serratia marcescens UCP 1549 for application as biodispersant. The experiment was carried out using wheat bran as substrate in solid-state fermentation (SSF) as low-cost technology. Biosurfactant production was verified by the reduction of surface tension (28.4 mN/m) and interfacial tension (4.1 mN/m) with n-hexadecane. Also, promising result of emulsification (94%) with burned motor oil was obtained. Acid precipitation yielded 52.0 g/kg dry substrate of biosurfactant, that was identified as an anionic compound of a lipopeptide nature by the Zeta potential and FTIR spectrum, respectively. The biomolecule showed stability under extreme conditions of temperature, pH and salinity, as well as low toxicity against the microcrustacean Artemia salina. In addition, the biosurfactant demonstrated excellent properties to dispersing burned motor oil in water (ODA = 50.24 cm2) and to washing of marine stones (100% removal of burned motor oil). Therefore, these results confirm SSF as a sustainable technology for the production of biodispersant by S. marcescens UCP 1549, promising in the bioremediation of marine ecosystems impacted by petroderivatives.Existential nihilism is on the rise in modern societies, but no previous work has investigated the social psychology of seeing no meaning in life. click here In the current research, five studies (N = 1,634) show that targets' existential nihilist beliefs elicit a range of negative stereotypes about personality traits, commonly valued social traits, and targets' ability to perform basic adaptive social tasks. Results demonstrate that these negative stereotypes are mediated by belief that the target is depressed more than the belief the target is non-religious or that the target does not plan for the future. link2 Unlike atheists, who are seen as competent, no positive stereotypes emerged for nihilists, suggesting both future research and interventions aimed at updating false beliefs about nihilists.In this study, a biofilm model was developed for sulfur-based denitrification in a moving bed biofilm reactor (MBBR), including mass transport as well as the conversion kinetics of sulfur-oxidizing bacteria (SOB). The experimental reactor simulated received a synthetic wastewater containing nitrate, sulfide and thiosulfate. The substrate affinity of SOB for intermediary elemental sulfur (S0) was found the most sensitive parameter. After estimating this single parameter, the model could adequately describe the steady state performance of the experimental MBBR. The experimental and simulated mass balances indicated that a fraction of influent sulfur accumulated into intermediate S0. Furthermore, the simulations showed that SOB were active over the entire thickness of a 200 µm biofilm. The simulation results allowed to quantify the extent of diffusion and substrate limitation. Scenario analyses indicated that the specific nitrogen loading rate could be increased from 0.05 to 0.20 kg N.kg-1 VSS.day-1 (corresponding to 0.22-0.86 kg N.m-2.day-1 expressed per biofilm surface area) while maintaining nitrogen removal efficiencies above 70%. An increasing specific nitrogen loading rate in this range resulted in an almost linearly increasing specific nitrogen removal rate, independent from whether it was realized through a decreasing HRT, carrier filling ratio or biofilm thickness.Mycobacterium tuberculosis has been observed to develop resistance to the frontline anti-tuberculosis drug rifampicin, primarily through mutations in the rifampicin resistance-determining region (RRDR) of rpoB. While these mutations have been determined to confer a fitness cost, compensatory mutations in rpoA and rpoC that may enhance the fitness of resistant strains have been demonstrated. Recent genomic studies identified several rpoB non-RRDR mutations that co-occurred with RRDR mutations in clinical isolates without rpoA/rpoC mutations and may confer fitness compensation. In this study, we identified 33 evolutionarily convergent rpoB non-RRDR mutations through phylogenomic analysis of public genomic data for clinical M. tuberculosis isolates. We found that none of these mutations, except V170F and I491F, can cause rifampin resistance in Mycolicibacterium smegmatis. The compensatory effects of five representative mutations across rpoB were evaluated by an in vitro competition assay, through which we observed that each of these mutations can significantly improve the relative fitness of the initial S450L mutant (0.97-1.08 vs 0.87). Furthermore, we observed that the decreased RNAP transcription efficiency introduced by S450L was significantly alleviated by each of the five mutations. Structural analysis indicated that the fitness compensation observed for the non-RRDR mutations might be achieved by modification of the RpoB active centre or by changes in interactions between RNAP subunits. Our results provide experimental evidence supporting that compensatory effects are exerted by several rpoB non-RRDR mutations, which could be utilized as additional molecular markers for predicting the fitness of clinical rifampin-resistant M. tuberculosis strains.We aimed to determine whether there were any differences in how surfers used their lead and trail limbs when landing two variations of a simulated aerial manoeuvre, and whether technique affected the forces generated at landing. Fifteen competitive surfers (age 20.3 ± 5.6 years, height 178.2 ± 9.16 cm, mass 71.0 ± 10.5 kg) performed a Frontside Air (FA) and Frontside Air Reverse (FAR), while we collected the impact forces, ankle and knee muscle activity, and kinematic data. A principal component analysis (PCA) was used to reduce 41 dependent variables into 10 components. A two-way MANOVA revealed that although there were no limb x aerial variation interactions, surfers generated significantly higher relative loading rates at landing for the trail limb compared to the lead limb (+28.8 BW/s; F(1,303) = 20.660, p less then 0.0001, η2 = 0.064). This was likely due to the surfers "slapping" the trail limb down when landing, rather than controlling placement of the limb. Similarly, higher relative loading rates were generated when landing the FA compared to the FAR (+23.6 BW/s; F(1,303) = 31.655, p less then 0.0001, η2 = 0.095), due to less time over which the forces could be dissipated. No relationships between aerial variation or limb were found for any of the kinematic or muscle activity data. Practitioners should consider the higher relative loading rates generated by a surfer's trail limb and when surfers perform a FA when designing dry-land training to improve the aerial performance of surfing athletes.
This study examined the mediating effect of life satisfaction and the moderating effect of the availability of community recreational facilities (CRF) in the association between loneliness and depression in rural older adults and urban older adults, respectively.

Quantitative data collected from 7547 Chinese older adults were analyzed using the SPSS macro PROCESS to test a moderated mediation model with life satisfaction as the mediator and CRF availability and residency type (rural vs. urban) as moderators.

Loneliness negatively predicted life satisfaction, life satisfaction negatively predicted depression, and loneliness positively predicted depression. The interaction of loneliness and CRF availability had a significant effect on depression for urban older adults but not for rural older adults. The direct impact of loneliness on depression differed significantly between rural and urban older adults.

Life satisfaction mediated the association between loneliness and depression in both rural and urban older adults; CRF availability unexpectedly boosted the effect of loneliness on depression in urban older adults but not in rural older adults. Given the same level of loneliness, urban older adults were more likely to be depressed than rural older adults.

Psychogeriatric practitioners may embed life satisfaction into intervention programs to minimize depression among older adults. Public administrators should examine the utilization of public facilities to avoid wasted resources and counterproductive effects on older adults. Lonely urban older adults deserve special attention.

To evaluate the pregnancy-related risk factors and incidence rate (IR) of systemic sclerosis (SSc) in primipara using the Health Insurance Review and Assessment database, covering all medical claims in South Korea.

From the database, 2,260,952 primipara aged 18-49 years from 2008 to 2018 were identified. The patients were followed up after their index delivery until December 2019. A Cox proportional hazard analysis was performed to identify the association of pregnancy-related factors with SSc development.

The SSc IR was 0.62 cases per 100,000 patient-years. Primipara had a higher risk of developing SSc after 3 years postpartum than in the first 3 years of delivery (OR = 1.98, 95% CI 1.36-2.78,
 < .001). A multivariate analysis showed that older age (35-49 years) (HR = 2.14, 95% CI 1.05-4.35,
 = .037) and a Caesarean section (CS) (HR = 1.86, 95% CI 1.10-3.15,
 = .021) are risk factors for SSc. At 3 years postpartum, CS (HR = 2.97, 95% CI 1.39-6.32,
 = .005) and a female infant (HR = 2.28, 95% CI 1.11-4.71,
 = .026) were associated with SSc development.

Having a CS, late childbirth, and a female infant are the risk factors for SSc in primipara. This study establishes the IR of SSc in primipara.

Farming has always been considered a physically active lifestyle. However, in recent times, with the increased use of technology and machinery, farmers may not be completing as much physical activity as before. link3 There is a lack of research on physical activity patterns, fitness, and perception about exercise among farmers. Physical activity patterns were assessed using ActivPAL₃ micro monitors for a duration of 7 consecutive days. Aerobic capacity was measured using a validated sub-maximal exercise test to calculate Metabolic Equivalent Task (MET) levels. The Exercise Benefits and Barriers Scale (EBBS) questionnaire was used to explore perceived benefits and barriers towards exercise. Farmers completed a mean (standard deviation) of 16,452 (5,170) steps and 124 (43) minutes of moderate-vigorous intensity physical activity (MVPA) daily.
