Chlorine dioxide is a broad-spectrum disinfectant against Shiga toxin-producing Escherichia coli and Listeria monocytogenes in agricultural water

Agricultural water is commonly treated with chlorine-based disinfectants, which are impacted by water quality. Understanding how water quality influences disinfectants such as chlorine dioxide (ClO2) against pathogenic bacteria is important for creating efficacious sanitation regimens. In this study, the minimum inhibitory concentration (MIC) of ClO2 needed to achieve a 3-Log reduction against Shiga toxin-producing Escherichia coli (STEC) and Listeria monocytogenes was compared across agricultural water samples. Sterile ddH2O served as a control to compare with environmental samples from Salinas Valley, CA, and laboratory standards. To test different dosages and water qualities, stock ClO2 was diluted in 24-well plates with target concentrations of 10, 5, 2.5, and 1.25 mg/L. Well plates were inoculated with pathogens and treated with sanitizer for 5 min. Following treatment, surviving pathogens were enumerated using viable cell counts. The results demonstrate that groundwater samples had the highest water quality of the environmental samples and required the lowest concentration of disinfectant to achieve 3-Log reduction against both bacteria, with MIC between 1.4 and 2.0 mg/L. Open-source samples had lower water quality and required a higher concentration of ClO2 for 3-Log reduction, with MIC between 2.8 and 5.8 mg/L for both pathogens. There was no correlation between pH, turbidity, or conductivity/TDS and reduction for either STEC or L. monocytogenes, suggesting no individual water metric was driving reduction. A lower dosage was required to achieve 3-Log reduction against STEC, while L. monocytogenes required greater concentrations to achieve the same level of reduction. Overall, these results help guide growers in using ClO2 as a broad-spectrum disinfectant and demonstrate its efficacy in reaching 3-Log reduction across agricultural water samples.

Transcriptional and physiological plasticity of the green peach aphid (Hemiptera: Aphididae) to cabbage and pepper plants.

Defensive metabolites and nutrient restriction of host plants are 2 major obstacles to the colonization of insect herbivores. The green peach aphid (GPA) Myzus persicae (Sulzer) broadly colonizes plants with diverse nutritional and defensive traits. However, how GPA adapts to nutritional and defensive traits within different plants remains largely unknown. To elucidate this, we first investigated the performances and transcriptomes of GPA feeding on cabbage Brassica oleracea and pepper Capsicum annuum. The green peach aphid had lower weight and fecundity when feeding on cabbage than on pepper. The transcriptomic analysis found 824 differentially expressed genes (DEGs), and 13 of the top 20 Kyoto Encyclopedia of Genes and Genomes pathways are related to nutrient metabolism, energy metabolism, and detoxification. Specifically, we found 160 DEGs associated with the metabolism of protein and amino acids, sugar and lipids, and xenobiotic substances, 86 upregulated in cabbage-fed GPA. Fourteen cathepsin B genes were strongly upregulated in cabbage-fed GPA, and were enriched in lysosome pathway and 2 dominated gene ontology terms peptidase activity and proteolysis. In addition, cabbage-fed GPA upregulated sugar and lipid digestion, while downregulated lipid biosynthesis processes. Furthermore, 55 metabolic detoxification enzyme genes were differentially expressed between GPA on 2hosts, and detoxification enzyme activities of GPA indeed changed accordingly to the host. Then, we found that cabbage has lower amino acids nutrition quality for GPA compared to pepper. Our results suggested that adjustment of nitrogen nutrient metabolism, sugar and lipid metabolism, and metabolic detoxification in a host-specific manner play crucial roles in the adaptations of GPA to different host plants.

Geographic inequities in hemodialysis access: a call to reassess dialysis facility locations in Brazil.

Patients who travel more than 60 min to undergo hemodialysis may experience higher mortality and lower quality of life. The primary aim of this study was to calculate the travel distance between patient city areas and dialysis facility care locations in Brazil, to highlight barriers and need to optimize access to chronic dialysis. We conducted a retrospective cohort study using claims data from the Brazilian Public Health System's database, focusing on kidney replacement therapy (KRT) by hemodialysis. Our study population comprised all patients undergoing hemodialysis in Brazil between January 2023 and December 2023. For patients from different city areas, we calculated the Haversine distance between the patient city area and the dialysis facility. We evaluated 154,788 patients who received hemodialysis funded by the Brazilian Public Health System. Fifty-nine percent of the patients underwent dialysis in the same city area. Overall, patients traveled a median (IQR) distance of 35.9 [19.5 - 64.2] kilometers to the facilities, 48% traveled more than 40 km, with a maximum traveling distance of 353 km. Notably, the median distance traveled was shortest in the Southeast (27.6 km) and longest in the North (84.3 km). The number of patients that traveled more than 40 km was lower in the Southeast (32%) and higher in the North region (77%). The travel distance to the dialysis facility is an important inequity to KRT access in Brazil. In the South and Southeast, where there is a higher dialysis unit density, patients have greater regional availability of dialysis centers, and shorter traveling distances than in the North, Midwest, and Northeast regions.

Range and Nature of Social Services for Children With Disabilities and Their Families: A Descriptive Study.

Children with disabilities and their families continue to face challenges in social inclusion and accessing resources. This study aimed to evaluate the availability and associated challenges of using services for these children and their families. A descriptive study was conducted to analyze social services for children with disabilities. Data were collected from the official websites of both public and private institutions across three regions in South Korea. These data included information on the service contents and the characteristics of the target beneficiaries. A total of 12,841 service units were analyzed and grouped into 10 domains and 35 categories of social services. The most frequently identified service content was "Healthcare," followed by "Child and family care" and "Community services." The most frequently used characteristic of target beneficiaries was "Residential area," followed by "Income level," "Benefit," and "Type of disability." The current services are limited in meeting the needs of children with disabilities, particularly in terms of selection criteria, service content, and the integration of policies and delivery systems, contributing to a lack of social inclusion and lower quality of life. Constructing a national scheme to expand eligibility and support tailored to individual circumstances and needs is necessary.

High prevalence of comorbidities in older adult patients with type 2 diabetes: a cross-sectional survey

BackgroundDiabetes is a global health problem, and its incidence and complications increase with the duration of the disease and over time. This increase in complications in older patients can lead to disability and a lower quality of life. This study aimed to investigate the rate of diabetes control and complications in older adults.MethodThis was a cross-section of an ongoing cohort of patients with type 2 diabetes mellitus (T2DM) aged 65 years and older. The clinical and laboratory characteristics of older adult patients with T2DM in good and intermediate health conditions were collected between 2010 and 2022.ResultsA total of 2,770 older adult patients with T2DM were enrolled, including 1,530(55.3%) female and 1,240 (44.7%) male participants. Metabolic syndrome, hypertension, and coronary artery disease were the most common comorbidities, affecting 1,889 (71.4%), 1,495 (54.4%), and 786 (29.2%) patients, respectively. Albuminuria was present in 626 (22.6%) patients, while retinopathy was detected in 408 (14.7%) patients, including 6% with proliferative retinopathy. Most patients were treated with oral antidiabetic agents (88.9%), with metformin being the most prescribed medication (85.6%). Statins were prescribed to 71.8% of the patients. The most prescribed antihypertensive medications were angiotensin receptor blockers and angiotensin-converting enzyme inhibitors, prescribed to 54% and 15% of patients, respectively. The hemoglobin A1c (HbA1c) goal (HbA1c < 7.5%) was achieved in 1,350 (56.4%) patients, and the low-density lipoprotein cholesterol (LDL-C) goal (LDL < 100) was achieved in 1,165 (45.6%) patients. Blood pressure control (BP < 140/90) was achieved in 1,755 (65.4%) patients. All three goals were achieved in 278 (10.3%) patients. There were no significant differences in clinical laboratory results and the patients’ characteristics based on gender.ConclusionThe rate of progression of complications in older adult patients is higher than the effectiveness of the treatment, indicating the need for increased social support for this age group.

Association Between Irritable Bowel Syndrome and Lower Urinary Tract Symptomatology: A Cross-sectional Study in Mexican Population.

This study aimed to investigate the clinical phenotype of urinary symptoms in patients diagnosed with irritable bowel syndrome, the factors associated with this overlap, and the impact of urinary symptoms on their quality of life. Irritable bowel syndrome is a common disorder, affecting up to 3.8% of the population. The overlap with other disorders of the gut-brain interaction, psychiatric disorders, and other somatic disorders is common. Moreover, the association between irritable bowel syndrome and urinary symptoms has been recognized, but the clinical phenotype remains unclear. This cross-sectional study involved patients with irritable bowel syndrome according to Rome IV. Lower urinary tract symptoms were classified using the International Continence Society's classification. Data on demographics, medical history, medication use, anxiety, depression, and quality of life were collected and analyzed using logistic regression analysis. The study included 428 subjects, 86 diagnosed with irritable bowel syndrome. Patients exhibited a higher prevalence of lower urinary tract symptoms (60.5%, 95% CI: 50.5-71.9). Multivariate analysis revealed associations between irritable bowel syndrome and lower urinary tract symptoms (OR: 2.49, 95% CI: 1.48-4.18, P=0.001), particularly storage urinary symptoms (OR: 1.94, 95% CI: 1.10-3.40, P=0.021). Patients with urinary symptoms reported significantly lower quality of life compared with those without these symptoms (50.8±17.2 vs. 76.7±21.8, P<0.001). Irritable bowel syndrome is associated with lower urinary tract symptoms, contributing to a significant reduction in quality of life. Clinicians should consider referring patients with irritable bowel syndrome and lower urinary tract symptoms to experts in urodynamics to provide targeted management.

Mathematical modelling, energy consumption, and quality evaluation of wheat seeds subjected to intermittent drying

AbstractThis work aims to evaluate the kinetic profile of intermittent drying of wheat seeds using traditional models from the literature and the fractional calculus technique. Furthermore, it aims to verify the application of the intermittent drying process on the amount of antioxidant compounds, protein, and lipid content of the grain, in addition to energy consumption to obtain the desired final moisture content of the wheat. It was verified that the prediction of drying kinetics by Page and fraction order models were similar (modelling efficiency varying between the range of 0.917–0.995, varying the drying condition and wheat cultivar). Regarding antioxidant compounds for the three wheat cultivars, it can be seen that the higher fraction of ethanol (74.0% and 90.36%) used for extraction had greater process efficiency. Regarding the protein content in the three wheat cultivars, lower drying temperatures and intermittency periods result in lower quality losses of material (12.3% for BRS‐Atobá wheat, 9.89% for BRS‐Jacana wheat, and 18.71% for BRS‐Sanhaço wheat). In terms of lipids, it was found that the influence of temperature was greater on the lipid content than on the protein content of the material (for the best drying condition, there were percentage decreases for the best condition of 36.16% for the BRS‐Atobá wheat, 34.9% for BRS‐Jacana, and 52.2% for BRS‐Sanhaço). Regarding energy consumption during the drying process, it can be seen that the conditions used for intermittency and drying time, in addition to the sample conditions, directly impact energy consumption.

PFAS Exposure is Associated with a Lower Spermatic Quality in an Arctic Seabird.

Several studies have reported an increasing occurrence of poly- and perfluorinated alkyl substances (PFASs) in Arctic wildlife tissues, raising concerns due to their resistance to degradation. While some research has explored PFAS's physiological effects on birds, their impact on reproductive functions, particularly sperm quality, remains underexplored. This study aims to assess (1) potential association between PFAS concentrations in blood and sperm quality in black-legged kittiwakes (Rissa tridactyla), focusing on the percentage of abnormal spermatozoa, sperm velocity, percentage of sperm motility, and morphology; and (2) examine the association of plasma levels of testosterone, corticosterone, and luteinizing hormone with both PFAS concentrations and sperm quality parameters to assess possible endocrine disrupting pathways. Our findings reveal a positive correlation between the concentration of longer-chain perfluoroalkyl carboxylates (PFCA; C11-C14) in blood and the percentage of abnormal sperm in kittiwakes. Additionally, we observed that two other PFAS (i.e., PFOSlin and PFNA), distinct from those associated with sperm abnormalities, were positively correlated with the stress hormone corticosterone. These findings emphasize the potentially harmful substance-specific effects of long-chain PFCAs on seabirds and the need for further research into the impact of pollutants on sperm quality as a potential additional detrimental effect on birds.

Static and Dynamic Modeling of Non-Performing Loan Determinants in the Eurozone

The issue of non-performing loans (NPLs) in a bank’s portfolio is important for a bank’s stability and sustainability. Their increased presence indicates a potential worsening of the economy and a lower quality of the bank’s assets. We estimated determinants of non-performing loans in the Eurozone for quarterly data 2015–2020. The results confirmed spatial spillover effects within Eurozone countries, which means that when a shock happens in one country in the Eurozone, it will also affect the other economies of the Eurozone area. Based on the Hausman test, a fixed-effects model was chosen as appropriate and showed that bank-specific and macroeconomic determinants significantly affect NPLs in these economies. In relation to previous studies that dealt with this issue, a co-integration analysis was introduced. A significant impact of return on assets, return on equity, and the loan-to-deposit ratio, as well as the gross domestic product, inflation, and exchange rate on NPLs in the short run and long run, was confirmed using a Pooled Mean Group (PMG) estimator. Bank management should customize credit policy based on both internal and external conditions to improve their performance, focusing on enhancing profitability and maintaining a lower loan-to-deposit ratio to reduce NPLs. The research suggests that a higher gross domestic product (GDP) growth rate is associated with fewer NPLs, while inflation uncertainty and a volatile exchange rate can increase NPLs, highlighting the importance of adjusting strategies to the macroeconomic landscape.

Oral Health-Related Quality of Life in Dutch Adults With Osteogenesis Imperfecta.

To explore the oral health-related quality of life and its possible risk factors among adults with Osteogenesis Imperfecta using the Oral Health Impact Profile (OHIP)-49 questionnaire. Secondary objectives were to investigate the impact of self-reported Osteogenesis Imperfecta, Dentinogenesis Imperfecta, and age on various dental parameters. A cross-sectional questionnaire was distributed online to 417 Dutch adults with Osteogenesis Imperfecta at three national referral centers. Multivariate linear regression was performed to identify indicators for OHIP-49 Scores. The effect of Osteogenesis Imperfecta, Dentinogenesis Imperfecta, and age on various dental parameters was investigated using logistic regressions (p < 0.05). One hundred and fifty-five questionnaires (37.2%) were suitable for analysis. Osteogenesis Imperfecta type III was significantly associated with higher OHIP-49 scores as compared to type I. Symptoms of temporomandibular disorders, missing teeth or dentures also increased the OHIP-49 scores significantly. Osteogenesis Imperfecta type IV and increasing age were associated with missing teeth. There was a 31.94 times (95% CI: 8.56-119.13) higher odds of tooth fracture with self-reported Dentinogenesis Imperfecta. Adults with Osteogenesis Imperfecta type III report a lower oral health-related quality of life compared to Osteogenesis Imperfecta type I adults.

Hydrodynamics and operation of a multistage fluidized bed with particles of super-high density

High-density particles are commonly used in fluidized bed reactors in uranium recycling processes of nuclear industry, where high fluidization quality (i.e. low gas-solids contacting efficiency) is difficult to achieve, resulting in various problems such as reduced conversion, low product selectivity, stronger equipment vibration and bad operating stability, etc. The objective of this study was to validate the feasibility and advantages of a multistage fluidized bed in processing a super-high-density powder. Wolfram carbide powder of true density of 15630 kg/m3 was used in a cold-model counter-current three-stage fluidized bed with downcomers. Stability of operation, operating range and hydrodynamics were systematically studied. The fluidization quality and operating stability were also compared with a single-stage conical fluidized bed of similar diameter and same solids inventories. The experimental results demonstrated that this high-density wolfram carbide powder could be fluidized and circulated continuously at this multistage fluidized bed, but lower fluidization quality was observed and the stable operating range is narrow. Narrower stable operating range was observed at higher solids circulation rates. At corresponding operating conditions, the fluidization quality of multistage fluidized bed is significantly better than that of the conical fluidized bed with a similar solids inventory.

Adverse Childhood Experiences in Parental History and how they Relate to Subsequent Observed Parent–Child Interaction: A Systematic Review

Abstract Background Adverse childhood experiences (ACEs) in parental history have been associated with higher self-reported rates of negative parenting behaviors and lower self-reported rates of positive parenting behaviors. Further research is needed to explore the association between parental ACEs and the observed parent–child interaction quality. Parent–child interactions are a potential pathway behind the continuity of ACEs across generations. Objective This review aimed to expand on existing literature by synthesizing evidence on the associations between parental ACEs and parent–child interactions, assessed through videotaped observations, the gold standard for interaction assessment. Methods A systematic literature search conducted in October 2022 in Medline, EMBASE, and PsycInfo identified twenty-four articles. The studies assessed parental childhood adversity and the quality of parent–child interaction across high- and low-risk samples. Results In 79% of studies, higher rates of childhood adversity were related to lower quality of observed parent–child interaction. Childhood abuse and neglect were linked to fewer positive and more negative parenting behaviors. Among household challenges, only witnessing family violence negatively impacted interaction quality. In 58% of studies, ACEs directly influenced interaction, while in 21% this effect was mediated by other factors. This pattern held across different sample types. Conclusions The evidence suggesting a relationship between parental ACEs and lower quality of parent–child interaction is robust, given the reliability and validity of observational measures. Considering the influence of the quality of parent–child interaction on a child’s development, interventions and prevention programs focusing on parent–child interaction should consider screening for parental ACEs.

Public Good Superstars: a Lab-in-the-Field Study of Wikipedia

Abstract Many field public goods are provided by a small number of contributors: the ‘superstars’ of their respective communities. This paper focuses on Wikipedia, one of the largest online volunteering platforms. Over 9 consecutive years, we study the relationship between social preferences – reciprocity, altruism, and social image – and field cooperation. Wikipedia editors are quite prosocial on average, and superstars even more so. But while reciprocal and social image preferences strongly relate to contribution quantity among casual editors, only social image concerns continue to predict differences in contribution levels between superstars. In addition, we find that social image driven editors – both casual and superstars – contribute lower quality content on average. Evidence points to a perverse social incentive effect, as quantity is more readily observable than quality on Wikipedia.

Stress and Quality of Life of Parents of Children With POLR3-Related Leukodystrophy: A Cross-Sectional Pilot Study.

Background: RNA polymerase III (POLR3)-related leukodystrophy is a rare, neurodegenerative disorder characterized by hypomyelination, hypodontia, and hypogonadotropic hypogonadism. Despite the challenges of caring for a child with POLR3-related leukodystrophy, few studies have examined parents' disease burden. We sought to investigate quality of life and stress levels amongst parents of children with POLR3-related leukodystrophy. Methods: 43 parents of 32 children completed questionnaires on demographics, stress, quality of life, coping mechanisms, and experience of injustice. Detailed clinical data was collected from all patients. Results: Mothers (t[27] = -8.66, P < .001) and fathers (t[16] = -4.47, P < .001) had lower quality of life scores compared to the normative population, yet 80% of parents' stress scores fell within the normal stress range. Parents' experience of injustice scores were high (>60). Correlations were found between and within parents' scores. Years since disease onset and certain life circumstances correlated to mothers' quality of life scores; however, no correlation was found between modifiable factors and fathers' quality of life scores. Helpful coping mechanisms included those that allowed parents to be involved in their child's life. Conclusions: This is the first study to assess stress and quality of life in this population. These results shed light on the importance of implementing services and social support to improve the well-being of parents.

Mild and Subtle Synthesis of β-Ketoenamine COFs with High Crystallinity and Controllable Solubility Guided by a Monomer Preassembly Strategy.

The stability of covalent organic frameworks (COFs) is crucial for their applications in demanding environments. However, increasing the stability of COFs often comes with challenges such as higher synthesis difficulty, lower crystal quality, and reduced controllability during synthesis, making it difficult to regulate dimensions and morphology, thereby impacting the processing and shaping of stable COFs. Herein, the study presents a novel confined polymerization approach guided by hydrogen bonding preassembly to synthesize a soluble and stable COF featuring β-ketoenamine linkage. The presence of relatively weaker hydrogen bonds accelerates the orderly arrangement of monomers, ensuring appropriate spacing, and orientations among functional groups. This facilitates efficient covalent polymerization, leading to the creation of the framework while minimizing the "self-correction" mechanism during crystal growth, thereby enhancing the efficiency of COF synthesis. Furthermore, this method offers precise control over the size of the synthesized COF. The resulting crystalline COF can be toggled between dissolution and precipitation states, facilitating the fabrication of mixed matrix membranes (MMMs) through leveraging the solubility properties of COF. Overall, this pioneering strategy yields valuable insights for advancing weak bond assembly-mediated confined polymerization approaches, the controlled synthesis of stable COFs, and the preparation and processing of soluble COFs in diverse applications.

An Exploration of Locomotor Syndrome among Geriatric Population – A Narrative Review

A locomotor disability in the geriatric population is a physical condition that impairs mobility and movement in older persons. It is frequently caused by age-related causes such as degenerative diseases, osteoarthritis, or neurological abnormalities. This impairment can have a substantial influence on older people's quality of life by limiting their ability to conduct daily activities independently, such as walking, standing, or climbing stairs. Addressing locomotor impairments in older persons is critical for preserving their mobility, independence, and overall well-being, ultimately improving their quality of life as they age.A comprehensive literature search was conducted, which were sourced from PubMed, google scholar, Japanese government websites, springer link, semantic scholar generated significant studies using the keywords like locomotor disability, older population, mobility, quality of life, aging. We included articles which were published from 2005–2024.Locomotive Syndrome (LS) affects a significant portion of the elderly population, with prevalence ranging from 8.4% to 50.3%, increasing with age and higher in women. It shows the correlations with osteoporosis and sarcopenia, suggesting potential shared risk factors or pathways. By this the older people tend to have lower quality of life, particularly concerning spinal alignment and trunk deformity. Exercise interventions, including locomotive training, aerobic exercise, and muscle training, are suggested for LS prevention. Vitamin D supplementation may benefit bone health and fall prevention in older individuals.Locomotor syndrome is a substantial concern, especially in ageing populations, with considerable implications for quality of life. Its prevalence, which is frequently associated with osteoporosis and sarcopenia, highlights the necessity of preventive measures including exercise and vitamin D supplementation. Recognising the impact of LS on mobility and well-being is critical for establishing focused interventions to prevent and manage its progression, thereby improving the overall health and independence of geriatric population.

Effect of Tree Density on Yield and Fruit Quality of the Grafted Hazelnut Cultivar 'Tonda Francescana®'.

Optimizing planting density is crucial for balancing resource competition, light penetration, and tree productivity in orchard systems. This study investigateed the impact of planting density on the yield and fruit quality of the hazelnut cultivar 'Tonda Francescana®' grafted onto Corylus colurna L. rootstocks. The research aimed to assess how different planting densities influenced light penetration, canopy volume, yield, and the nutritional profile of hazelnuts during their sixth growing season. Three planting densities were tested: 625, 1250, and 2500 trees per hectare (low, medium, and high density, respectively). The results show that medium-density planting provided the best balance between light availability, canopy development, and yield efficiency. The synthesis of monounsaturated fatty acids (MUFA) and α-tocopherol (vitamin E) was more prominent in the medium-density system (80.2% and 10.3%, respectively), suggesting a favorable metabolic response to moderate competition for resources. In contrast, high-density planting yielded the most per hectare (2898 kg/ha) but exhibited lower individual tree productivity (1.16 kg). Low-density planting had the highest light penetration (53%) but lower overall yield (822 kg/ha) and quality, with greater starch accumulation in the fruit. In general, medium-density planting optimized both yield and kernel quality, with potential implications for orchard management and breeding strategies to enhance hazelnut production and nutritional value.

Experimental Investigation of Post-Dryout Heat Transfer with R-134a at High Pressures

An experimental study of post-dryout (PDO) heat transfer in the coolant R-134a was performed in a vertical round tube with upward flow. Experiments were conducted at high pressures from 28.4 bars up to 39.8 bars, corresponding to a reduced pressure of 0.7 to 0.98, respectively. Mass flux was varied in the interval of 300 to 1500 kg/m2∙s, and overall equilibrium vapor quality was between −1.88 and 4.89. Depending on the settings of the experimental parameters, the heat flux was varied from around 11 to 100 kW/m2. The uniformly heated tube had an inside diameter of 10 mm and a heated length of 3000 mm. In total, more than 10 000 PDO data points were obtained. In the PDO region, the wall temperature distributions had similar behavior across the pressure range. At the occurrence of dryout, the wall temperature suddenly increased until it reached a peak. For higher mass flux, the wall temperature decreased after reaching the peak, followed by a second temperature increase with a lower slope. For lower mass flux, the wall temperature kept increasing after the dryout point. The temperature peak after the dryout point was smaller at higher pressure, while this effect was even stronger near the critical pressure. Likewise, the vapor quality corresponding to the first peak shifted to even lower values with increasing pressure. Furthermore, it was found that at increasing pressure and at increasing mass flux, the dryout location and the total temperature distribution shifted toward lower vapor qualities. In addition, several PDO correlations were assessed, and a new correlation for high-pressure conditions was developed and compared with the results of the existing ones.

Government affiliation, analyst behavior and the economic consequences

AbstractA significant number of regional brokerage firms in China are owned by their respective local governments. We use this context to examine how local government affiliation affects brokerage firms’ research activities. Using a sample of analyst reports from 2013 to 2021, we find that analysts working at local government‐affiliated brokerage firms are more likely to cover firms within the local government's jurisdiction than non‐affiliated analysts. Local government‐affiliated analysts enjoy an information advantage, as evidenced by the issuance of more accurate earnings forecasts for local firms, compared to those of non‐affiliated analysts. The effect is stronger for local firms with lower information quality. Additionally, local government‐affiliated analysts show more optimism in stock recommendations, but not in earnings forecasts, for local firms, compared to non‐affiliated analysts. The effect is more pronounced for local firms that receive more local government subsidies, operate in regions with greater local government intervention or during the COVID‐19 pandemic and the National Congress conferences, and require more capital market support. The results of this study advance our understanding of the key determinants of analyst performance and provide new evidence in the debate on the role of government intervention in financial institutions.
