Microstructure and ionic conductivity investigation of samarium doped ceria (Sm0.2Ce0.8O1.9) electrolytes prepared by the templating methods

Sm0.2Ce0. 8O1.9 (SDC20) electrolytes were synthesized with cellulose templating (CT) and PVA templating (PVAT) methods. Powder characteristics were examined using TG/DTA, XRD, and SEM. Pellets are sintered at various temperatures for different durations. Mean grain sizes were calculated from SEM micrographs using the linear intercept method. Grain growth behavior of the electrolytes was investigated and the dominant diffusion mechanism was examined. The grain growth activation energies were obtained for the first time for the mentioned electrolytes prepared by the mentioned methods. The ionic conductivities were calculated by electrochemical impedance spectroscopy. The highest ionic conductivity value was found to be 0.050 S cm−1 for the cellulose templating method.
Dietary Intervention and Supplements in the Management of Psoriasis: Current Perspectives

Abstract Nutrition is a complex topic encompassing diet and a variety of supplements including vitamins, fish oil, herbal products, and probiotics. Patients with psoriasis display high interest in understanding the potential impact of nutritional modifications on their psoriasis. In this review, we examine the evidence for nutritional interventions in psoriasis and summarize important concepts. We found that certain diets, such as low-calorie diets for obese patients, gluten-free diets for patients with comorbid celiac disease, and the Mediterranean diet, may have benefits for psoriasis patients. Supplements in general do not show strong evidence of benefit, though more studies are required given the heterogeneity of these trials. Finally, the gut microbiome has drawn considerable interest in recent years, with specific probiotics showing promising results for psoriasis patients and warranting further exploration.
Neutronics modeling of the CROCUS reactor with SERPENT and PARCS codes

This paper reports the methodology used for the neutronic modelling of the CROCUS reactor and discusses the challenges encountered during the process. Full-core steady-state neutronics solutions were computed with the PARCS code. The Serpent Monte Carlo code was used for few-group constant generation. The full-core Serpent model of the reactor was also used as reference for the comparison against PARCS results. The comparison between Serpent and PARCS solutions was successful, achieving good level of agreement for eigenvalue (418 pcm difference) and control rod reactivity worth (1 pcm difference). In terms of radial neutron flux profiles, differences in the inner fuel region were within 5% and 1% for the thermal and fast fluxes respectively. However, in the outer fuel lattice region, differences were considerably higher due to the mismatch between PARCS nodes and heterogeneous fuel pins. Also, PARCS post-processing for intranodal reconstruction proved to be an effective way to observe heterogeneities within nodes, which cannot be otherwise captured by PARCS solution. Some of the modelling challenges were overcome with the use of transport-corrected diffusion coefficients and the implementation of albedo boundary conditions. A parametric analysis reflected the importance of the transport correction of diffusion coefficients for producing good eigenvalues in reactor cores with large neutron leakage.
Sleep Problems and 6-Sulfatoxymelatonin as Possible Predictors of Symptom Severity, Adaptive and Maladaptive Behavior in Children with Autism Spectrum Disorder

In children with autism spectrum disorder (ASD), sleep disturbances are a frequent comorbidity with an adverse effect on their behavior and functioning. It was suggested that melatonin deficit is at least partly responsible for the sleep problems. The study aimed to investigate, in a sample of 56 children with ASD aged 2.8–13.3 years, if the sleep problems and melatonin secretion can serve as predictors of adaptive functioning and severity of the ASD core symptoms. We demonstrated that, after adjustment for age, the Sleep score assessed by the Children’s Sleep Habits Questionnaire predicts the Adaptive behavior composite score only in children younger than 6 years, and the preferred predictive model is for the domain Socialization. The age-adjusted Sleep score predicted Externalizing and Internalizing maladaptive behavior, with a near-zero contribution of age to the relationship between the Internalizing maladaptive behavior and Sleep score. After adjustment for age, the reduced night-time melatonin secretion predicted a higher severity of ASD symptoms in the domain Social affect and the Calibrated Severity Score, but not the sleep problems. Our results emphasize the importance of assessing sleep problems as a modifiable predictor of behavior in children with ASD and support the hypothesis about the role of melatonin in pathophysiology of ASD.
Pedestrian Patterns at Railway Platforms during Boarding: Evidence from a Case Study in Switzerland

The boarding/alighting process at railway platforms is an important determinant of the railway system performance and depends on the characteristics of passengers, the layout of the platform, and the rolling stock. This research aims to increase the understanding of the process, providing a methodological approach to model the passengers’ behaviour when boarding at railway platforms. Adequate criteria were selected to define the so called “boarding cluster” and an easy mechanism was developed to select the boarding clusters. Passenger flow data collected at Bern railway station in Switzerland was used to test the proposed approach. The results show that (a) the clusters near the doors grow in the longitudinal direction with a rate of 6:1 between the length and width of clusters, and that (b) the growth curves rise quickly when clusters are still small, i.e., at the beginning of the boarding/alighting activity. Further research is needed to extend the validation of the model, considering other variables, such as critical pedestrian densities which occur at specific hot spots near obstacles at platforms.
The role of the river in the functioning of marginal fen: a case study from the Biebrza Wetlands

Study region The area of interest is the Upper Biebrza Valley, located in NE Poland. Study focus We examined water exchange at the river-fen interface in a near-natural wetland system using the combined field research-modeling approach. The authors chose the Biebrza River as the research object: it is a specific case of fen marginal valley rivers, and it flows in the peat layer without direct connection to the mineral soil layer. Our case study introduces two new aspects not yet considered in the scientific literature: (1) the riparian aquifer is fen and (2) the river has no direct contact with the mineral layer. The following research questions were investigated: What is the role of the river in feeding and draining a fen? Which drainage paths are important for water exchange in a near-natural river-fen system? How important are the morphological settings for the river-fen relations? We applied a systematic hydrological research approach based on field measurements and observations of the river and surrounding fen hydrological characteristics, as well as on the modelling results. New hydrological insights for the region We demonstrated that morphological settings have a significant influence on river-fen relations. We also demonstrated that due to the undeniable need to introduce increased protection and restoration of marginal fens, we may focus on river status in narrow valleys; however, in the wide valleys, the limitation of the drainage layer by decreasing the intensity of evapotranspiration is more promising. We propose to distinguish zones in the fen river valley to include them when proposing protection or conservation plans.
Chemical Compositions of Leaf Protein Concentrate and Bagasse of Pride of Barbados (Caesalpinia pulcherrima) Leaves obtained from three Different Locations in Benin City, Nigeria

To optimize food and feed production in Nigeria and meet protein demands, viable options need to be explored. Therefore, this study aimed to determine the chemical composition of Pride of Barbados leaf protein concentrate and bagasse. Freshly harvested Pride of Barbados leaves were obtained from three different locations in Benin City and processed for its leaf protein concentrate and bagasse using heat coagulated method. Pride of Barbados leaf protein concentrate and bagasse were analysed for proximate and mineral compositions using standard analytical procedures. Proximate analysis revealed that the dry matter, crude protein, ether extract, crude fibre, ash, and nitrogen free extract contents of Pride of Barbados leaf protein concentrates were 91.17%, 31.12%, 8.33%, 7.92%, 8.2%, and 35.3%, respectively. Pride of Barbados bagasse had a lower crude protein (9.22%) but higher fibre content (10.72%) compared to those of Pride of Barbados leaf protein concentrate. Na, K, Ca, and Mg were the most abundant minerals in Pride of Barbados leaf protein concentrate and bagasse. Chromium was very low in the leaf protein concentrate and bagasse. Proximate compositions were significantly (p<0.05) affected by location. Pride of Barbados leaf protein concentrate and bagasse can be used as livestock feed ingredient.
Shedding Light onto the City Blues Myth—The Potential of Stimulating and Activating Effects of Urban Public Spaces and the Role of City Relatedness

The present study aims to investigate whether a sense of relatedness to a city helps to broaden understanding of the restorative potential of urban public spaces. Findings based on a sample of German adults (n = 249) confirm that people experience relatedness to a city. The study’s 3 × 3 (built, mixed, natural environment) × (average, livability environment, bird’s-eye view) design revealed disordinal interactions for being away, fascination, preference, mental fatigue, and stimulating and activating effects associated with cities. This implies that humans’ place perceptions are more complex than previously assumed. Both city and nature relatedness were relevant covariates of these findings. Surprisingly, the construct ‘activating effects’, was found to be mostly perceived as more positive for mixed and built environments compared to natural environments. Thus, complementing restorative environments research by introducing a measure for city relatedness significantly enhances understanding of the potential of urban public spaces for promoting human health and well-being.
‘Prevention is better than cure’: warning for comedications in patients receiving immune checkpoint inhibitors to avoid acute kidney injury

ABSTRACT The introduction of immune checkpoint inhibitors (ICI) has resulted in significant improvement in cancer care, but has been accompanied by the occurrence of immune-related adverse events (irAEs). Also, kidney irAEs have been reported, and the most frequent one is acute tubulointerstitial disease which impacts renal and overall prognosis. There is an unmet need to stratify renal risk in oncologic patients, to allow individualized monitoring and therefore, early detection of ICI-related acute kidney injury (ICI-AKI). Although risk factors for ICI-AKI have been described in previous case–control studies, where ‘cases’ were ICI-AKI patients and ‘controls’ ICI-treated patients without AKI, there is limited epidemiologic knowledge concerning patients developing different irAEs. In this issue of the Clinical Kidney Journal, Gerard et al. describe five factors that were associated with the development of ICI-AKI: older age, previous chronic kidney disease, and concomitant use of fluindione, non-steroidal anti-inflammatory drugs and proton pump inhibitors. These findings suggest that ICI may be a ‘second hit’ that precipitates AKI caused by a concomitant drug. These results urge an increased focus to prevent the prescription of potential nephrotoxic drugs in ICI-treated patients, avoiding iatrogenic events.
Hukou-Based Rural–Urban Migration Status and Domestic Violence Against Wives in China: Implications for Policy and Practice

Migration in China has been shaped by the household registration system (hukou) that determines stratified citizenship among migrants. Adopting a feminist intersectionality lens, this study investigated how hukou institution, class, and regionality intersect to have an impact on migrant women's experience of physical, psychological, and sexual violence perpetrated by their husbands. The analysis of nationally representative data from the third wave of Women's Social Status Survey in China (n = 5411) revealed that compared to rural non-migratory wives, (a) return migrants were more likely to experience all three forms of violence; (b) temporary migrants had higher odds to suffer from psychological violence; and (c) permanent migration was not a significant predictor of any form of domestic violence (DV). The findings indicate that migration should be examined in all its complexity from an intersectionality perspective and a within-gender heterogeneity framework may be necessary if we aim to address the multiplicity in migrant women's lives. In practice, attempt to alleviate the negative impact of migration on DV requires reforms or the abolition of the hukou system, and programs and services should be provided in particular to return women migrants who face triple oppression of institutional discrimination, socioeconomic stratification, and regionality marginalization.
Valuation of mortgage-backed securities using Brownian bridges to reduce effective dimension

The quasi-Monte Carlo method for nancial valuation and other integration problems has error bounds of size O((log N) k N ? 1), or even O((log N) k N ? 3=2), which suggests signiicantly better performance than the error size O(N ? 1=2) for standard Monte Carlo. But in high dimensional problems this beneet might not appear at feasible sample sizes. Substantial improvements from quasi-Monte Carlo integration have, however, been reported for problems such as the valuation of mortgage-backed securities, in dimensions as high as 360. We believe that this is due to a lower eeective dimension of the integrand in those cases. This paper deenes the eeective dimension and shows in examples how the eeective dimension may be reduced by using a Brownian bridge representation.
Association of Serum Osteoprotegerin Level With Myocardial Injury and Cardiovascular Calcification in Chronic Kidney Disease Patients

Background Chronic kidney disease has emerged as a significant independent risk factor for cardiovascular disease. Cardiovascular calcification is an active process involving a complex interaction of inducers and inhibitors. High sensitivity cardiac troponin T assay detects troponin T with higher sensitivity and precision at an earlier point of time than the conventional assays, and is associated with poor outcomes. Serum osteoprotegerin is classed as an inhibitory factor for cardiovascular calcification. It is involved in the pathological processes of vascular damage and linked to the excess cardiovascular morbidity. The aim of the present study was to evaluate the extent of cardiovascular calcification and serum high sensitivity cardiac troponin T level, and their association with serum osteoprotegerin level in patients with chronic kidney disease stages 3–5. Methods 90 chronic kidney disease patients were enrolled in this study, and they were divided into two groups: group (1) included 45 non-dialysis-dependent chronic kidney disease patients (stages 3–5) and group (2) included 45 chronic hemodialysis patients. Each group further subdivided according to the presence of cardiovascular calcification into subgroup A and B. Vascular calcifications were assessed by lateral lumbar, pelvis and hands X-ray radiographs. Valvular calcification was assessed by echocardiography. Serum cardiac troponin T was measured by high sensitivity assay and serum osteoprotegerin was measured by ELISA. Results Cardiovascular calcification distribution was 22.2% in group (1) and 33.3% in group (2). Serum osteoprotegerin and troponin T in calcification groups (1A and 2A) were significantly higher than non-calcification groups (1B and 2B; P < 0.001). Osteoprotegerin correlated positively with high sensitivity cardiac troponin T (rs = 0.72, P < 0.001). cardiovascular calcification correlated positively with osteoprotegerin, troponin T, and phosphorus. osteoprotegerin and phosphorus were significant independent predictors of cardiovascular calcification at cut-off values ≥4.6 ng/L and ≥6.95 mg/dl, respectively (P < 0.001). Serum phosphorus and creatinine were independent predictors of osteoprotegerin (P < 0.001 and 0.048, respectively). Conclusion Osteoprotegerin is strongly associated with cardiovascular calcification and high sensitivity cardiac troponin T. In addition, there is a positive association between calcification and troponin T. This suggests a role for osteoprotegerin in the pathogenesis and risk stratification of cardiovascular calcification and myocardial injury in chronic kidney disease patients with a potential role as a therapeutic target.
Large Eddy Simulation of Boundary Layer Transition Mechanisms in a Gas-Turbine Compressor Cascade

Large eddy simulation (LES) is used to explore the boundary layer transition mechanisms in two rectilinear compressor cascades. To reduce numerical dissipation, a novel locally adaptive smoothing (LAS) scheme is added to an unstructured finite volume solver. The performance of a number of subgrid scale (SGS) models is explored. With the first cascade, numerical results at two different freestream turbulence intensities (Ti's), 3.25% and 10%, are compared. At both Ti's, time-averaged skin-friction and pressure coefficient distributions agree well with previous direct numerical simulations (DNS). At Ti = 3.25%, separation-induced transition occurs on the suction surface, while it is bypassed on the pressure surface. The pressure surface transition is dominated by modes originating from the convection of Tollmien–Schlichting waves by Klebanoff streaks. However, they do not resemble a classical bypass transition. Instead, they display characteristics of the “overlap” and “inner” transition modes observed in the previous DNS. At Ti = 10%, classical bypass transition occurs, with Klebanoff streaks incepting turbulent spots. With the second cascade, the influence of unsteady wakes on transition is examined. Wake-amplified Klebanoff streaks were found to instigate turbulent spots, which periodically shorten the suction surface separation bubble. The celerity line corresponding to 70% of the free-stream velocity, which is associated with the convection speed of the amplified Klebanoff streaks, was found to be important.
The impact of strategic inventory and procurement strategies on green product design in a two-period supply chain

This study analyses the impact of power structures and strategic inventory on the development-intensive and marginal-cost-intensive green product types under three procurement strategies. The results suggest that (i) in the manufacturer-Stackelberg game, the retailer retains strategic inventory to earn higher profits. The retailer's decision improves profit for the manufacturer and greening level of the product; (ii) for the marginal-cost-intensive green product, the power structures and procurement strategies cannot make any impact on the greening level and the retailer cannot build up strategic inventory under retailer-Stackelberg game; (iii) under the Nash game, the procurement decision creates conflict between the supply chain members for marginal-cost-intensive green products; (iv) if the retailer does not maintain strategic inventory or procures product in a single lot, then the manufacturer prefers to produce marginal-cost-intensive products and retailer prefers to sale development-intensive products to receive maximum profits under manufacturer-Stackelberg game. The optimal preferences are concurrent under retailer-Stackelberg game, but not under the Nash game; (v) single-period equilibrium solutions may exhibit sub-optimal characteristics, but two-period planning can lead to exemplary outcomes in the perspective of the greening level and profits of the supply chain members.
Helicity conservation laws for fluids and plasmas

Helicity conservation laws in fluid dynamics and magnetohydrodynamics are studied. The rate of fluid helicity dissipation in nonisentropic flow is derived, and the derivation is generalized, introducing the concept of chirality and reinterpreting the Ertel-Katz law as one of a family of laws dictating the variation of the rate of dissipation of some helicity along streamlines. Woltjer's two helicity conservation laws in MHD are reviewed, and the covariant derivation of the second is given. The two Oron helicities are introduced, their conserved character is established, and a type B law arising from the second Oron helicity's conservation is proved. Departures from perfect MHD are addressed, estimating the magnetic helicity (MH) dissipation in magnetized fluids with finite conductivity and deriving a type-B law for the MH dissipation rate in a particularly simple kind of imperfect MHD flow. An Ertel-Katz type law is derived for poorly conducting magnetized fluids. 25 references.
The Effect of Trust, Tax Rates and Tax Awareness on the Compliance Level of MSME Taxpayers at KPP Pratama Batam Selatan

Since the discovery of the Corona virus in Indonesia, economic growth has contracted at 2.97% and 5.32% respectively in the first and second quarters of 2020. Indonesia has just emerged from recession starting in the 3rd quarter with economic growth of 5.05%. But overall, in 2020 the Indonesian economy fell 2.07% compared to the previous years which was stable at 5% (BPS, 2021). This decline in economic growth has had a significant economic impact. In 2020 and 2021, several times the government implemented Large-Scale Social Restrictions (PPKM) so that many businesses, both small and large scale, felt the impact, and even closed their businesses. This systematic impact also affects state revenues from the tax sector. Targeted tax revenues according to Presidential Decree No. 72 of 2020, The Directorate General of Taxes (DGT) of the Ministry of Finance of Rp. 1,198.82 trillion has only realized Rp. 1,069.98 trillion or 89.25%. State revenues from the tax sector long before the outbreak of the Covid-19 pandemic actually tended to be low. One sector that contributes to state tax revenues that should be large but far from the target is the Micro, Small and Medium Enterprises (MSME) sector. Registered MSMEs have a TIN (Setiawan, 2020). Therefore, it is not surprising that the tax contribution from the final PPh of MSME taxpayers is only around Rp. 7.5 trillion or approximately 1.1% of the total income tax revenue.
