Postoperative Quality of Life after Single-Visit Root Canal Treatment Performed with Reciprocating Shaping Systems: An Observational Study

Postoperative pain is a frequent complication of root canal treatment. It could worse patients’ quality of life (QoL) and it may be associated to several factors, including the shaping technique. The aim of the study was to compare the impact of WaveOne Gold (WOG) and WaveOne Classic (WOC) reciprocating instrumentation on postoperative QoL after single-visit primary root canal treatment. Healthy subjects with pulp necrosis on multirooted teeth were observed. Canal shaping was performed with WaveOne Gold Primary (n = 25) or WaveOne Classic Primary (n = 29) and canal filling was completed with a carrier-based technique. Mean and maximum scores for postoperative pain were assessed through a Visual Analogue Scale (VAS) and QoL indicators were evaluated with a self-assessment questionnaire based on a Likert scale. Postoperative pain curves were similar in both groups (mean pain p = 0.43; maximum pain p = 0.27) and quality of life indicators showed no significant differences (p > 0.05). There was a more favourable trend of QoL values in the WOG group, reaching statistical significance on day six posttreatment (p = 0.021). Within the limitations of the study, reciprocating instrumentation may have an impact on patients’ QoL, but the innovative geometrical and alloy properties of the WaveOne Gold seemed to induce a faster resolution of the postoperative symptoms.
Seismic Structural Curvature Volume Extraction With Convolutional Neural Networks

Structural curvatures are widely used seismic attributes that help interpreters to understand both structural and stratigraphic features. Traditional structural curvature extractions are mainly calculated from dip estimations through lateral scanning of seismic events, which is not only a very time-costing approach but also influenced by parameter settings, seismic frequency, and data quality. In this article, we propose a deep learning-based volumetric curvature extraction approach that directly derives structural curvature volumes from the seismic response. To realize the above approach, we develop a suite of sample generation and augmentation methods to synthesize seismic samples with accurate curvature labels. Then, a multitask end-to-end convolutional neural network architecture and a geometric loss function are proposed to establish the volume mapping model from complex seismic responses to the most positive and negative curvature volumes. The performance of the proposed curvature extraction approach is evaluated on both the synthetic data and the Netherlands F3 field seismic data. Extensive experiments demonstrate that curvature volumes extracted with the proposed approach are not only more accurate and less influenced by the noises of poststack seismic data but also more friendly for structure interpretation. Therefore, we believe that our proposed deep learning curvature extraction approach can be a useful tool for further seismic structure interpretation practices.
The Nexus Between Economic Freedom and Tourist Arrivals: Evidence from Mediterranean Countries

Mediterranean countries are indispensable places of tourism with their world-famous shores, wonderful climate and impressive historical places. The aim of this paper is to investigate the relationship between tourist arrivals and economic freedom indicators such as government integrity, tax burden, government spending, business freedom and trade freedom. For this purpose, the panel vector autoregression (PVAR) method was used for a Mediterranean countries sample covering the period from 1996 to 2016. The results of causality testing showed that the tourist arrivals have a bidirectional causality relationship with each explanatory variable, while the coefficient estimates showed that an increase in economic freedom indices affected tourist arrivals negatively in Mediterranean countries. That is, economic freedoms do not mean an advantage for tourists without supportive public policies for tourism. The test results suggest that policymakers should take into account the various aspects of the tourism sector, particularly natural resources and environmental factors, while making policies that increase economic freedom in Mediterranean countries
A Hybrid Intervention Combining Group-Based Physical Activity and an Individual Goal-Oriented Approach for Children with Developmental Disabilities: A Pre-Post Intervention Study

ABSTRACT This study aimed to examine the outcomes and feasibility of a hybrid group-based intervention combining physical activity and an individual goal-oriented approach for children with developmental disabilities. We employed a single-arm pre-test/post-test repeated-measures design. Outcome measures were based on participants’ achievement of individual goals in daily activities, as well as physical and psychosocial functioning. We also report qualitative data from one example case. The intervention consisted of eight sessions, each incorporating a goal-oriented approach and including group-based physical activities, practice with daily activities, and team meetings. Participants were seven children (all boys; age: 7y 10mo ± 1y 6mo) diagnosed with autism spectrum disorders, attention-deficit/hyperactivity disorder, developmental coordination disorder, or a combination thereof. Significant improvements were observed in participants’ achievement of individual goals and their physical functioning. No significant changes in psychosocial functioning were noted. The example case showed the changes related to everyday life. No participants dropped out, and no complaints or severe accidents or injuries were recorded. All participants expressed hopes of continuing to participate in this program. This approach has high feasibility and could help to amplify the effects of physical activity interventions.
The influence of auditory information on performance in table tennis

It is well-known that visual information is essential for anticipation in table tennis but it not clarified whether auditory cues are also used. Therefore, we performed two in-situ studies, in which novices (study A) and advanced players (study B) responded to strokes of a real opponent or a ball machine by returning with forehand counters (study A) and forehand top spins (study B) to a given target area on the table. We assessed the parameters “hit quality” and “subjective effort”. In study A, we provided four conditions: normal, a noise-cancelling headphone and earplugs to dampen auditory information, other noise-cancelling headphones and earplugs to remove almost all environmental sounds, and the same head-phones with additional bright noise to remove all sounds. In study B, we performed three tests (irregular play and regular play with an opponent and response to regular balls of a ball machine) under two conditions: normal and noise-cancelling headphones with the additional bright noise. In both studies, no significant differences between all conditions for “hit quality” and “subjective effort” (all p>0.05) were found. We conclude that auditory information, as well as their volume, have no influence on the hit quality in table tennis for novices and advanced players.
Need Analysis of Virtual Laboratories For Science Education In Jambi, Indonesia

The needs of technological advancement which is infused into education system are more and more inviting thorough researches since digital environment influences educational settings. In specific, virtual laboratories as the digital environment is now not used only in engineering and computer science fields but also in educational field in general. Digitalized teaching aids, web-based learning, e-learning etc. are such possible prospective fields that need virtual labs in them. In regard to that, this study is initiated to conduct a need analysis of virtual labs for Jambi province context through library research. This study employs documentary analysis techniques to assimilate reliable information regarding virtual labs from the related literatures. Purposively, this study selects online journals that are correlated to virtual labs and analysed the variables, methods, and results of study. This study finds that studies done yield few shortcomings of virtual labs usages to only the lost opportunity of students to involve their senses during the use of virtual labs. However, in general virtual labs usages contribute benefits to science education such as: a) Virtual labs assist students to link between theoretical and scientific concepts to practical laboratory techniques and skills; b) Virtual labs provide simulations that make students more engaged in learning scientific phenomena; c) Although some important opportunities of learning experiences are not provided by virtual labs such as sensory involvement in learning, most virtual labs are developed to fulfil the characteristics of teaching aids; d) Virtual labs abbreviate the preparation steps of practicum activities, hence they make class-time used effectively; and e) Virtual labs allow students to repeat experiment for multiple times. In addition, virtual labs usages also bring prospects to some important aspects of educational field namely financial resources, academic advancement, technological computer simulation improvement, and cultural aspects. This study suggests the Jambi Education Board to recommend virtual labs usages at schools to equip science education as supplemental and supporting teaching aids.
Molecular epidemiology, risk factors, species distribution, antifungal susceptibility and outcome of candidemia in the capital of Iran: a prospective study

Background Candidemia is a major cause of morbidity and mortality among patients receiving immunosuppressive therapy and those hospitalized with serious underlying diseases despite the commencement of antifungal therapy. We investigated the molecular epidemiology, clinical characteristics, comorbidity risk factors, species distribution, antifungal susceptibility profile, and outcome of candidemia to provide appropriate perspectives in Tehran, Iran. Methods A prospective observational study of all patients diagnosed with candidemia was performed at two referral teaching hospitals in Tehran. Demographic characteristics, underlying diseases, risk factors, clinical symptoms, and laboratory analyses were mined. Results One-hundred and fifty-two Candida isolates from 89 patients with candidemia were recovered. The overall crude mortality was 47.2%. The most common underlying disease was sepsis (48.3%) followed by malignancy (46.1%), renal failure/ dialysis (43.8%), and Hypertension (40.0%). C. albicans (43.8%) was the most frequent causative agent followed by C. glabrata (21.3%), C. parapsilosis complex (15.7%), C. tropicalis (11.2%), and C. lusitaniae (3.4%). Result of antifungal susceptibility test show that activity of all the four azole antifungal agents was low against non-albicans Candida species, especially C. tropicalis. Conclusion Increase in non-albicans Candida species with reduced susceptibility to antifungal drugs might be alarming in high-risk patients. Therefore, accurate knowledge of predisposing factors and epidemiological patterns in candidemia are effective steps for managing and decreasing the mortality rate in candidemia.
Components of Cowpea Resistance to the Seed Beetle Callosobruchus maculatus (Coleoptera: Chrysomelidae: Bruchinae)

Abstract Cowpea, Vigna unguiculata (L.) Walp. , serves as a major source of dietary protein in many tropical and subtropical regions around the world. To identify loci associated with agronomically desirable traits, eight elite cowpea cultivars were systematically inter-crossed for eight generations to yield 305 recombinant inbred lines. Here, we investigated whether these founder parents also possess resistance to the seed beetle Callosobruchus maculatus (F.), a highly destructive post-harvest pest. We estimated larval survival in seeds, egg-to-adult development time, adult mass at emergence, and seed acceptance for oviposition. Survival varied significantly among cowpea cultivars, but the pattern was complicated by an unexpected source of mortality; on three cultivars, mature larvae in a substantial fraction of seeds (20–36%) exited seeds prematurely, and consequently failed to molt into viable adults. Even if such seeds were eliminated from the analysis, survival in the remaining seeds varied from 49 to 92% across the eight parents. Development time and body mass also differed among hosts, with particularly slow larval development on three closely related cultivars. Egg-laying females readily accepted all cultivars except one with a moderately rugose seed coat. Overall, suitability ranks of the eight cultivars depended on beetle trait; a cultivar that received the most eggs (IT82E-18) also conferred low survival. However, one cultivar (IT93K-503-1) was a relatively poor host for all traits. Given the magnitude of variation among parental cultivars, future assays of genotyped recombinant progeny can identify genomic regions and candidate genes associated with resistance to seed beetles.
Influence of laminar-to-Turbulent transition on model scale propeller performances. Part II: cavitating conditions

ABSTRACT The numerical study presented in Part I (Gaggero, 2020), focused on the prediction of the laminar-to-turbulent boundary layer transition on model scale propellers, is extended to cavitating conditions. In the previous study, the application of the γ-Reθ Local Correlation Transition Model allowed for significant improvements in model scale performance prediction and highlighted the role of the turbulence intensity on the transition onset. In this second part of the study, the influence of the same transition model on the inception and development of cavitation is considered. To this aim, a modification of the Schnerr-Sauer mass transfer model, useful for engineering-oriented applications, is proposed to account for the role of the laminar boundary layer in the inception and development of the leading edge sheet cavitation. The proposed analyses, compared with the available measurements at the cavitation tunnel, confirm the improvements of the numerical predictions using the modified model.
Community structure and seasonal changes in population structure of pelagic polychaetes collected by sediment traps moored in the subarctic and subtropical western North Pacific Ocean

Community structure and seasonal changes in the population structure of pelagic polychaetes were studied based on zooplankton samples collected by sediment traps moored at 200 m depth in the subarctic and subtropical western North Pacific throughout the year. Eight species belonging to seven genera and seven families occurred at the subarctic station, while twelve species belonging to ten genera and seven families were identified at the subtropical station. Polychaete abundance was 5.37 ± 0.44 ind. m-2 day-1 (annual mean ± standard error) at the subarctic station, and 1.36 ± 0.15 ind. m-2 day-1 at the subtropical station. Polychaete abundance at the subarctic station was high from May to August, but no seasonal patterns were observed at the subtropical station. The dominant species in the subarctic was Tomopteris septentrionalis, which accounted for 62.9% of annual mean abundance; at the subtropical station, the dominant species was Pelagobia sp. (22.8%). In the subarctic, small specimens of T. septentrionalis (<3 mm in body length) occurred only in winter (December-March). No clear seasonal changes in population structure of the subtropical Pelagobia sp. were detected. The latitudinal patterns we observed in the polychaete communities of the western North Pacific were similar to those previously observed in the eastern North Pacific. Changes in the population structure of T. septentrionalis suggest that the life cycle of this species is seasonal in the subarctic region.
Croatian leadership and Jews in the 1990s

Aim: What was the attitude of the first Croatian president Franjo Tuđman and the Croatian leadership towards the Holocaust and the Jewish community in Croatia in the 1990s? Some considered Tuđman a Holocaust denier because of the purportedly controversial parts of his 1989 book Bespuca povijesne zbiljnosti (Wastelands of Historical Reality). The Croatian leadership was accused of minimizing World War II crimes of the Ustasha regime and rehabilitating the World War II Independent State of Croatia. Methods: We analyzed archival documents, Tuđman’s published correspondence, controversial parts of his Wastelands of Historical Reality, his public statements, biographical writings of contemporary Croatian leaders, and newspaper articles. We scrutinized the Serbian propaganda against Croatia in the 1990s, the position and role of the Jewish community and prominent Jews in Croatian public life as well as the relations between Croatia and Israel. Findings: The Croatian leadership and the Jewish community maintained good relations in the 1990s. Some prominent Croatian Jews actively advocated for Croatia’s international recognition and refuted certain authors’ and some Jewish international circles’ accusations of antisemitism among Croatian leadership. Jews participated at the highest levels of Croatian government. Democratic changes at the beginning of the 1990s enabled national, religious, political and other freedoms for minorities in Croatia, including the Jewish community. Still, some authors considered Tuđman an anti-Semite and a Holocaust denier. These opinions were partly shaped by quotes from the Wastelands of Historical Reality taken out of context and published by Serbian propagandists. This propaganda successfully shaped the false perception of official antisemitism in Croatia and has contributed to the delay in the establishment of the diplomatic relations between Croatia and Israel for more than five years after Israel had recognized Croatia. Conclusion: There is no evidence for claims of political antisemitism in Croatia in the 1990s. This article sheds light on this widely manipulated topic and provides a basis for further researchs.

Determinants have an important impact in the process of creating and realizing an e-commerce strategy, with all e-commerce companies regardless of their size being aware of their practical impact and importance. It can be concluded the importance and quality of determinants of online shopping behavior correspond to the type of strategy and strategic management process in terms of e-commerce competitiveness.
Species composition, abundance pattern of Bemisia tabaci and its co-inhibitant on eggplants under different chemical fertilization condition

This study assesses the interaction, relationship and recorded several species of insectacarines pest on the underside of eggplant leaves. Variation of infestation levels by a community of insect-acarines detected on the leaves namely Whitefly Bemisia tabaci, aphids Myzus persicae, thrips Thrips palmi, mite and spider mite Tetranychus cinnabarinus caused serious damage at the initial stage of plant growth with flowering and fruiting stage. Different effects by fertilizer levels were observed affected the presence of insect-acarines and dominancy of major pest. The result also showed that all the insectspest was colonized competitively on the leaves for every sampling date due to treatments effect. Whitefly was found to be the most dominant on eggplants which resulted in more than 50% from other insect pest composition, particularly at higher fertilizer levels. Some occasions described that the predator-prey relationship has been identified as a major role in the habitat competition. There was an obvious trend of competitor pest of whitefly such as aphids’ population was found higher than whitefly in all treatments. Generally, this study suggests that the dominant species and the first invader probably could suppress or mediate the other competitor significantly once they occupied on the same quality of host plants.
RHEOLOGICAL BEHAVIOUR AND IN VITRO RELEASE PROFILES OF NAFTIFINE TOPICAL HYDROGELS

The study is presenting the formulation and manufacturing process of 15 hydrogels formed by different cellulose derivative containing 1% naftifine hydrochloride dissolved in a mixture of cosolvents with low amounts of alcoholic components. The obtained products were evaluated by modelling their flow behaviour and by studying the in vitro release profile in vertical diffusion cell systems. The formulations showed a typical pseudoplastic behaviour. The range of variation in diffusion coefficient values is remarkably low, compared to structural differences easily detectable and demonstrated by rheological behaviour analysis. The increase in the concentration of the cellulose derivative matrix former leads to proportional decreases in diffusion coefficient values for naftifine, correlated with structural parameters.
Native or non-native instructors? A case study on foreign language speaking anxiety in EFL classroom

The purpose of this study is to investigate foreign speaking anxiety in the Non-Native and Native Instructors’ classroom. To this end, Horwitz, Horwitz & Cope’s (1986) Foreign Language Classroom Anxiety Scale (FLCAS) was administered to 469 EFL learners studying at three universities. According to the results, there are differences in the items such as preparation and negative evaluation in Non-Native and Native Instructors’ classroom. When the variables such as age, gender and the length of study were taken into consideration, it was found that the participants’ length of study is a significant factor in foreign language speaking anxiety. However, no correlation was found between the anxiety and age and gender.
Morningness, eveningness chronotype traits and sleep quality among healthcare workers in shift work-a cross-sectional study from a tertiary care hospital in Kerala

Sleep is basic physiological requirement, as described in Maslow's hierarchy of needs, for the human body to function normally. The suprachiasmatic nuclei of hypothalamus, circadian clock, controls and regulates sleep/awake cycle daily metabolic rhythm, sleep/wake cycle, feeding behaviour and hormonal secretions. Sleep quality is associated with alertness and our response to environment and sleep quality have an impact on many aspects of employee behaviour within the workplace including alertness at work, error-making and absenteeism. Economically driven studies have explored the impact of shift work rather than individual measures of sleep dysfunction on occupational outcomes such as absenteeism. The sleep disorders of nurses have been reported as a risk factor for patient safety. Prevalence of poor sleep quality among nurses reported from different countries varies between 60-80%. Chronotypes, individual typology (morning-type, evening-type, intermediate type), is an attribute of human beings that reflects their circadian phases of body temperature, hormone levels, and eating and sleeping patterns. Morning-types have a relatively early circadian phase and go to sleep early and wake up early, while evening-types have a relatively late circadian phase and are active ABSTRACT
