Effect of different kinematics on the cyclic fatigue resistance of Reciproc Blue file in different canal curvatures

Introduction: Ni-Ti instruments used in reciprocation reduce instrument separation. Reciproc-Blue is a thermally-treated NiTi single reciprocating system coated by an oxide layer caused by the thermomechanical process improving fatigue resistance. Aim: To evaluate the effect of different kinematics on the cyclic fatigue resistance of the Reciproc-Blue file and examine the influence of different canal curvatures on its cyclic fatigue resistance. Method: Eighty new Reciproc-Blue files divided into four groups (n=20) according to the reciprocation angles 150°CCW– 30°CW, 210°CCW–30°CW, 90°CCW–40°CW and 360°CCW(continuous-rotation), each group was subdivided into two subgroups (n=10) according to the canal curvature 45°and 60°angles. All instruments were operated until the fracture occurred, Cyclic fatigue resistance was determined by recording the time to fracture in seconds. Data were statistically analyzed by applying ANOVA test followed by Post Hoc Tukey test at 95% significance level. Results: all reciprocating motions yielded a significant increase in time to failure when compared to continuous rotation in both canal curvatures. There was a significant difference in time to failure among all reciprocating groups in both canal curvatures. All experimental groups revealed greater cyclic fatigue resistance at 45°compared to 60°angles of curvature. There was no significant difference in the length of the fractured fragment for all tested groups in both canal curvatures. Conclusion: Movement kinematics has a significant influence on the cyclic fatigue life of Reciproc-Blue instruments. Also, Increasing the angle of progression for each reciprocation cycle decreases the cyclic fatigue resistance of NiTi instruments.
Pseudo rough Vol-of-Vol through Markovian Approximation

We discuss a possible framework for a (pseudo) rough vol-of-vol model through a multi-factor Markovian approximation of the vol-of-vol process. We identify a key martingale condition which may allow to express the VIX in terms of the solution of a certain Riccati ordinary di(cid:27)erential equation. We derive this equation and provide su(cid:30)cient conditions for the existence of solutions. We also provide some partial results regarding the martingale condition. In particular, we verify a local martingale condition
Bamboo (Poales, Poaceae): An Important Maintainer of Immature Mosquitoes (Diptera: Culicidae) in a Biodiversity Hotspot in the City of Rio de Janeiro, Brazil

Although tropical forests are home to most of the global diversity, they suffer from the most significant knowledge gaps concerning their fauna. Despite its high biodiversity, Brazil is facing an alarming destruction of habitats, with species becoming extinct before they can be discovered or described via science. Therefore, there is an urgent need to expand wildlife inventories, including entomofauna surveys. The present study aimed to analyze the bionomic aspects and the influence of abiotic factors on mosquito fauna whose immature phases develop in two bamboo species, Guadua tagoara and Bambusa vulgaris, in Tijuca National Park, Rio de Janeiro, Brazil. Immatures were collected in 10 artificially drilled bamboo plants, in five stalk internodes per plant, at two sampling points, from March 2022 to March 2023, during 23 collections. A total of 1845 immatures were obtained, 72.14% at sampling point 1 and 27.86% at sampling point 2. Of this, 1162 individuals reached adulthood, belonging to the following species: Culex iridescens, Culex neglectus, Haemagogus leucocelaenus, Orthopodomyia albicosta, Sabethes identicus, Sabethes melanonymphe, Sabethes purpureus, Toxorhynchites bambusicola, Toxorhynchites sp. , Trichoprosopon compressum, Trichoprosopon pallidiventer, Wyeomyia arthrostigma, Wyeomyia codiocampa, Wyeomyia lutzi, Wyeomyia oblita, Wyeomyia personata, Wyeomyia serrata, and Wyeomyia sp. The Tijuca National Park is a tourist spot and receives a large number of visitors. Thus, humans can become an accessible food source for mosquitoes in this area, making the species survey critical since important arbovirus vectors have been recorded in Rio de Janeiro.
Do Snow-Based Sport Participants Intend to Purchase Products from Environmentally Friendly Companies?

ABSTRACT To extend the literature on consumer pro-environmentalism, this study explores the relationships between individuals’ participation in outdoor, snow-based sport; their pro-environmental behavioral intentions (PBIs); and their intentions to purchase from environmentally friendly companies (PI-EFCs). Participants were recruited from an international ski resort in Japan (N = 286). The results indicate that snow-based sport involvement influences PI-EFCs through PBIs when associated actions were perceived to be directly relevant to the outdoor sports environment (i.e. PBI to reduce CO2 emission). Conversely, the relationship was not mediated by PBIs when environmental issues were less relevant to a snow-based sport environment (i.e. air pollution, water pollution). The findings imply that pro-environmental marketing efforts can be an effective approach to increase PI-EFCs when corporations focus on sport-specific environmental issues germane to snow-based sport participants such as global warming.
A unified approach to parasitic gap and across‐the‐board constructions: Evidence based on Mandarin Chinese

Despite the lack of consensus on English facts, this study demonstrates that both parasitic gap (PG) and across‐the‐board (ATB) constructions in Mandarin Chinese exhibit paralle effects in variable binding reconstruction, while also displaying asymmetries in gap licensing categories. I argue that these patterns in Mandarin Chinese align with the sideward movement approach, supporting a version of the unified approach to deriving both constructions. Specifically, the gaps in question are filled by variables, consistent with both constructions being derived via sideward movement. The observed asymmetries lend support to the view that the licensing of ATB gaps is more permissive than that of PGs, as additional conditions (such as the Parallelsim Requirement) on coordinate structures can license sideward movement in ATB sentences.
Digital Capability and Performance of Micro, Small, and Medium-Scale Enterprises: A Review

Digital Capability is considered one of the cardinal strategies that MSMEs can adopt to enhance their competitiveness and improve performance. However, several business enterprises continue to experience various setbacks, such as poor performance and slow growth, where almost 70 percent of SMEs close their businesses before their third year in operation. This may be attributed to an unfavorable business environment and rapid technological changes, requiring an equal and efficient change in business strategy. This paper, therefore, sought to assess the effect of digital capability on the performance of micro, small, and medium enterprises. Specifically, the study aimed to evaluate the influence of digital infrastructure, organization competency, and digital operations on the performance of Micro, Small, and medium-scale enterprises. The study adopted a qualitative survey design where the scholar did a literature search on different online databases, mainly Google Scholar, EBSCO, and Science Direct. The study was desk research, which involved reviewing academic journals, scholarly articles, and published research. The findings indicated that digital infrastructure, organization competency, and digital operations significantly positively affected the performance of micro, small, and medium enterprises. The study recommended that further studies be carried out using quantitative techniques to assess further the relationship between digital capability and the business sustainability of MSMEs
Exploring Symptom Clusters in Chinese Patients with Diabetic Kidney Disease: A Network Analysis

Purpose The research on symptom management in patients with diabetic kidney disease (DKD) has shifted from separate symptoms to symptom clusters and networks recently. This study aimed to evaluate the unpleasant symptoms of DKD patients, and to investigate how these symptom clusters could affect patients. Methods 408 DKD patients were recruited in this cross-sectional study. The symptoms of DKD patients were measured using the modified Dialysis Symptom Index. Network analysis was employed to evaluate the symptom network and the characteristics of individual nodes, while factor analysis was utilized to identify symptom clusters. Results Blurred vision was the most prevalent symptom among DKD patients. The symptoms identified as the most distressing, severe, and frequent were light headache or dizziness, arteriovenous fistula/catheterization pain, and diarrhea, respectively. Five symptom clusters were obtained from factor analysis, and the most central symptom cluster in the entire symptom network was sexual dysfunction. Conclusion This study identified five symptom clusters in Chinese DKD patients, with sexual dysfunction emerging as the most central cluster. These findings carry significant clinical implications, underscoring the necessity of assessing symptom clusters and their associations to enhance symptom management in DKD patients. Further research is essential to elucidate the underlying mechanisms of symptoms and to clarify the associations among symptoms in DKD patients across different disease trajectories or treatment modalities.
Can Three-Dimensional Power Doppler Detect Placental Involvement in pregnant women with COVID-19? An observational study

Objective: Placental involvement in pregnant women with covid–19 has been proved by postnatal histopathological examination in many studies even in absence of fetal infection. Whether this placental involvement can be detected prenatally using ultrasonography has not been investigated. Materials and Methods: This is a cross-sectional study including 40 women attending for second trimester scan divided into two groups; Group A (pregnant women with mild Covid-19 infection requiring home isolation), Group B (control group). Three-dimensional (3-D) power Doppler ultrasonography of the placenta using VOCAL technique, calculating the placental volume and placental vascular indices including Flow Index (FI), VI (Vascularity index), VFI (Vascularity flow index). The Pulsatility index (PI) of the uterine artery was also measured. Results: Baseline characteristics were similar between both groups. Placental volume was significantly higher in Covid group than control group. Mean FI was significantly less while VI and VFI were higher in Covid group compared to control group. Uterine artery doppler did not show any differences between both groups. Conclusion : Mild Covid-19 infection can have an impact on placental volume and placental vascularity and perfusion observed by three-dimensional ultrasonography. In mild cases, whether these changes are transient or permanent, and whether it can have an impact on pregnancy outcomes need to be investigated in future research.
Leaf extract of Garcinia atroviridis promotes anti-heat stress and antioxidant effects in Caenorhabditis elegans

Introduction: Garcinia atroviridis has been used for traditional medicines, healthy foods and tea. The chemical compositions and biological activities of fruit, stem bark and root have been widely studied. However, the phytochemical components and the biological activities in Garcinia atroviridis leaves (GAL) are limited. This research aims to study the phytochemical components and the stress resistance effects of GAL in Caenorhabditis elegans (C. elegans). Methods: To investigate the chemical components and antioxidant activities of GAL extract, the ethanol extract was characterized by liquid chromatography-quadrupole time-of-flight mass spectrometry (LC-QTOF MS) analysis and C. elegans was used to evaluate the effects of GAL extracts on longevity and stress resistance. Results and discussion: The results revealed that the ethanol extract of GAL possesses free radical scavenging activities. Furthermore, GAL extract increased the lifespan of C. elegans by 6.02%, 15.26%, and 12.75% at concentrations of 25, 50, and 100 μg/mL, respectively. GAL extract exhibited improved stress resistance under conditions of heat and hydrogen peroxide-induced stress. The survival rates of GAL extract-treated worms were significantly higher than those of untreated worms, and GAL extract reduced reactive oxygen species (ROS) accumulation. Additionally, GAL extract treatment upregulated the expression of stress resistance-associated genes, including gst-4, sod-3, skn-1, and hsp16.2. GAL extract supplementation alleviated stress and enhanced longevity by inducing stress-related genes in C. elegans. The observed effects of GAL extracts may be attributed to the stimulation of oxidant enzymes mediated through DAF-16/FOXO and SKN-1/NRF2, as well as the enhancement of thermal defense in C. elegans. Collectively, this study provides the first evidence of the antioxidant activities of GAL and elucidates the underlying mechanisms of stress resistance.
Characteristics of intestinal microbiota in preterm infants and the effects of probiotic supplementation on the microbiota

Objective In this study, we investigated the characteristics of the intestinal microbiota of preterm infants, and then analyzed the effects of probiotics supplementation on intestinal microbiota in preterm infants. Methods This study enrolled 64 infants born between 26 and 32 weeks gestational age (GA) and 22 full-term infants. 34 premature infants received oral probiotic supplementation for 28 days. Stool samples were obtained on the first day (D1) and the 28th day (D28) after birth for each infant. Total bacterial DNA was extracted and sequenced using the Illumina MiSeq Sequencing System, specifically targeting the V3-V4 hyper-variable regions of the 16S rDNA gene. The sequencing results were then used to compare and analyze the composition and diversity index of the intestinal microbiota. Results There was no significant difference in meconium bacterial colonization rate between premature and full-term infants after birth (p > 0.05). At D1, the relative abundance of Bifidobacterium, Bacteroides, and Lactobacillus in the stool of preterm infants was lower than that of full-term infants, and the relative abundance of Acinetobacter was higher than that of full-term infants. The Shannon index and Chao1 index of intestinal microbiota in preterm infants are lower than those in full-term infants (p < 0.05). Supplementation of probiotics can increase the relative abundance of Enterococcus and Enterobacter, and reduce the relative abundance of Escherichia and Clostridium in premature infants. The Chao1 index of intestinal microbiota decreased in preterm infants after probiotic supplementation (p < 0.05). Conclusion The characteristics of intestinal microbiota in preterm infants differ from those in full-term infants. Probiotic supplementation can reduce the relative abundance of potential pathogenic bacteria and increase the abundance of beneficial microbiota in premature infants.
The Mediating Role of Satisfaction between Emotional Values, Social Values, and Behavioral Intentions of Muslim Students

The study focuses on the behavior of Muslim students’ intentions to revisit halal tourist attractions that have added value. Additionally, it explores the act of revisiting Borobudur Temple as a means of fostering a sense of patriotism and national pride. This study contributes to the existing body of literature on perceived value by investigating the relationship between emotional values, social values, and satisfaction as a mediating factor. The study involves a significant number of participants, including 115 Muslim students living in the Java province. The existing circumstances are transitioning into the new normal, requiring the ongoing implementation of environmental health policies due to the presence of COVID-19. The data analysis utilizing Partial Least Squares (PLS) reveals that emotional and social values have a positive impact on Muslim students’ intention to engage in repetitive behavior. This study also found that there was an indirect influence of the satisfaction variable as a mediation. The primary elements that contribute to enhancing the motives of Muslim students to revisit Borobudur Temple are behavioral intentions and the satisfaction of Muslim visitors. Furthermore, it is essential for stakeholders in tourism-related businesses to enhance awareness and support the development of halal tourism by offering halal tourism services and recognizing its potential as a thriving sector within the tourism industry.
Public investment as a growth driver for a commodity-exporting economy: Sizing up the fiscal-monetary involvement

The study presents a solution to maximize public investment as a growth driver for commodity-exporting economies. The solution is to compensate for the low efficiency of public investment by drawing on internal and external factors within an active fiscal and monetary policy framework. For this, the paper introduces a quantitative model that implements a golden rule of public finance in a resource boom backed by a sovereign wealth fund under an active monetary policy stance. The modeling results show that mobilizing windfall resource revenues to finance increased public investment can limit a crowding-out effect through proper resource allocation and change the sectoral structure in favor of the final goods sector. As confirmed by the sensitivity analysis, the low efficiency of public investment can be partially offset by a less restrictive monetary policy response to fiscal dominance, but this leads to excessive volatility in financial indicators. However, if the public debt burden is an issue due to a more robust fiscal dominance regime, a higher tax rate on exported raw materials can be used to maintain sustainability. By developing a policy goals domain, the paper initiates a discussion that can direct policy recommendations toward a promising growth path by maximizing the public investment driver in the complex policy environment of fiscal-monetary interaction.
Impacts of climate change on coastal ecosystems of Bangladesh

The Sundarbans mangrove ecosystems of Bangladesh’s south-west coastal region are extremely vulnerable to climate change and its impacts particularly salinity increase. Hence. the main aim of this study is to evaluate the impacts of salinity increase on the Sundarbans mangrove ecosystems at different scales (i.e., mangrove vegetation and Royal Bengal Tiger habitat) and on the adjacent coastal communities for identifying target oriented measures to adapt to salinization. To achieve this aim, we have used a multidisciplinary research framework where both qualitative and quantitative approaches are combined. The study reveals that global climate change, regional hydrological modifications and local socio-economic shifts are the major processes associated with rapid salinization across the south-west coastal region of Bangladesh. Salinity increase and its range of processes are not only contributing to reduce world’s largest and last remaining tract of mangrove’s (i.e., Sundarbans) biodiversity, but also degrade quality tiger-habitat requirements (through, for example, availability of fresh drinking water, sufficient prey population and diverse vegetative cover). Furthermore, intensification in salinity across the south-west coast of Bangladesh has become an extensive threat for human health and livelihoods. Further changes in salinity and its range of processes will make future efforts to protect and manage these diverse ecosystems more intricate. Therefore, target oriented adaptation pathways have been developed to cope with and to enhance resilience to salinization. Thus the study provides novel insights for effective and target oriented large-scale adaptation planning in the studied region.

Depositional environment, hydrocarbon generation and expulsion potential of the middle Permian Pingdiquan source rocks based on geochemical analyses in the eastern Junggar Basin, NW China

ABSTRACT As the most important source rocks in the eastern Junggar Basin, the middle Permian Pingdiquan (P2p) source rocks have attracted increasing attention after the discovery of tight oil in the Shazhang uplift. The P2p source rocks are widely distributed (up to 7546 km2) and have an elevated thickness in the eastern Junggar Basin. To explore the P2p tight oil resource in the eastern Junggar Basin, 113 core samples from 34 exploration wells were analysed geochemically and re-examined for their organic matter abundance, type and thermal maturity, hydrocarbon potential and sedimentary environment. Geochemical analysis results indicate that the P2p source rocks are fair to good source rocks dominated by Type II kerogen, presently in a low mature–mature stage, and biomarkers and trace elements indicate deposition in a terrestrial to coastal environment under oxic to dysoxic, and fresh to brackish conditions, with possible intermittent seawater influence, implying proximity to the open sea. Based on hydrocarbon expulsion modelling, hydrocarbon expulsion began at 0.87% Ro, and the peak expulsion occurred at 1.1% Ro. Hydrocarbon generation intensities in the Shazhang uplift and the Wucaiwan sag are relatively large, with values centred at 4–6.5 million t/km2 and 4–6 million t/km2, respectively, with total hydrocarbon generation and expulsion from the P2p source rocks approximately 4.56 × 109 t and 1.44 × 109 t, respectively, indicating significant tight oil exploration potential in the eastern Junggar Basin. The Shazhang uplift and the Wucaiwan sag are two hydrocarbon expulsion centres in the study area with the largest hydrocarbon expulsion intensity centred around the Shazhang uplift, exceeding 3 × 106 t/km2. We suggest that the area with high hydrocarbon expulsion intensities is a favourable target for tight oil accumulation and exploration.
