Introduction: The objective of the study is to evaluate the oral hygiene awareness and the utilization of oral health services by the patients visiting dental OPD of Kalinga Institute of Dental sciences, Bhubaneswar. Methods: A cross sectional based study was conducted among 204 patients . A structured self-administered questionnaire was employed as the instrument for data collection. Statistical analysis was done using SPSS version 26.0 using Chi square test.The Confidence Level and the Level of Significance were set at 95% and 5%, respectively. Results: In our study females were 29.4% (n=60) and 70.6% (n=144) were males.In the study maximum number of participants were found to be in the age range of 21-30 years with 56.9% (n=116) followed by age range of 31-40 years with 13.2% (n=27). Conclusion: The current study reveals a lack of knowledge about oral health among patients visiting dental OPD. Thus there is an urgent need for comprehensive educational programs to promote good oral hygiene and impart education about correct oral hygiene practices.
Changes in egg production, egg quality and egg nutritional values of laying hens in response to dietary supplementation with green tea water extracts

ABSTRACT Our previous studies demonstrated that low-grade tea had some beneficial effects on egg production performance and egg quality. Extracts derived from low-grade tea had high levels of active ingredients. Thus, this study investigated the effects of green tea water extracts (GTWE) supplementation on egg production, egg quality and egg nutritional value of laying hens. A total of 192 laying hens were randomly allotted to four groups T0, T1, T2 and T3, which fed with basal diet supplemented with 0%, 0.3%, 0.5% and 1.0% GTWE, respectively. Results showed that 0.3% GTWE supplementation increased egg production and improved feed conversion ratio significantly, while 0.5% and 1.0% GTWE supplementation resulted in no significant effects. Furthermore, 1.0% GTWE had adverse effects on feed intake. GTWE treatment improved egg quality, as shown by the increased albumen height and Haugh unit. At the same time, GTWE treatment improved the egg nutritional value, as presented by the increased content of vitamin E and lecithin. On the other hand, GTWE treatment decreased cholesterol, triglyceride, and malonaldehyde levels. However, the strength and thickness of eggshell were negatively affected. The comprehensive analysis suggested low dose of GTWE could be used to developing a desired functional feed supplement.
Decreased Interhemispheric Functional Connectivity and Its Associations with Clinical Correlates following Traumatic Brain Injury

Objective To explore the interhemispheric functional coordination following traumatic brain injury (TBI) and its association with posttraumatic anxiety and depressive symptoms. Methods This was a combination of a retrospective cohort study and a cross-sectional observational study. We investigated the functional coordination between hemispheres by voxel-mirrored homotopic connectivity (VMHC). Grey matter volumes were examined by voxel-based morphometry (VBM), and microstructural integrity of the corpus callosum (CC) was assessed by diffusion tension imaging (DTI). The anxiety and depressive symptoms were evaluated with the Hospital Anxiety and Depression Scale. Results The VMHC values of the bilateral middle temporal gyrus (MTG) and orbital middle frontal gyrus (MFG) were significantly decreased in TBI patients versus the healthy controls. Weakened homotopic functional connectivity (FC) in the bilateral orbital MFG is moderate positively correlated with anxiety and depressive symptoms. The white matter integrity in the CC was extensively reduced in TBI patients. In the receiver operating characteristic analysis, the VMHC value of the orbital MFG could distinguish TBI from HC with an area under the curve of 0.939 (sensitivity of 1 and specificity of 0.867). Conclusion TBI disrupts the interhemispheric functional and structural connection, which is correlated with posttraumatic mood disorders. These findings may serve as a clinical indicator for diagnosis.
Antibacterial Activity of Copper Nanoparticles against Xanthomonas campestris pv. vesicatoria in Tomato Plants

Copper-based bactericides have appeared as a new tool in crop protection and offer an effective solution to combat bacterial resistance. In this work, two copper nanoparticle products that were previously synthesized and evaluated against major bacterial and fungal pathogens were tested on their ability to control the bacterial spot disease of tomato. Growth of Xanthomonas campestris pv. vesicatoria, the causal agent of the disease, was significantly suppressed by both nanoparticles, which had superior function compared to conventional commercial formulations of copper. X-ray fluorescence spectrometry measurements in tomato leaves revealed that bioavailability of copper is superior in the case of nanoparticles compared to conventional formulations and is dependent on synthesis rather than size. This is the first report correlating bioavailability of copper to nanoparticle efficacy.
Production function estimation controlling for endogenous productivity disruptions

We modify the standard production function estimation framework to incorporate endogenous disruptions in the productivity process due to lumpy firm investment. We investigate the differences between the existing (baseline) approach and our own (disruption) on a large proprietary panel of Greek Manufacturing firms. We find significantly different production function estimates and different results for subsequent inference. The implied average levels of productivity and magnitude of endogenous disruptions are different. The baseline model cannot capture the full dynamics of disruption costs, which extend across time. The decomposition of Aggregate Productivity Growth is substantially different under the disruption model.
ORGANIZATIONAL SERVICE INNOVATION: THE CASE OF THE RENSSELAER SATELLITE VIDEO PROGRAM AT THE RENSSELAER POLYTECHNIC INSTITUTE

The objective of this study is to develop a model for organizational service innovation success by exploring in detail the reasons behind the success of an organizational service innovation. Since prior researchers on organizational innovation have approached the issue from the purpose of adoption, change, and incremental new service development, it is difficult to extend their conclusions for organizational service innovations because of the contextual differences in these three lines of research. The unique attribute of this study is that it considers a new-to-the-world innovation. The Rensselaer Satellite Video Program (RSVP) of the Rensselaer Polytechnic Institute (RPI) is a distance education program for working professionals. It was set up as a transparent organization within RPI to handle all of the needs and wishes of distance students and corporate customers. The study combines multiple data collection methods such as interviews and archival sources because multiple data collection techniques make the triangulation possible to provide strong conclusions. Designed and tested before the interviews, a case study protocol with open-ended questions was used during interviews. The results of the study indicate that there are four major dimensions for the success of organizational service innovations Each dimension is explained and theoretical and practical implications as well as future research directions are discussed.
The Effect of Corporate Governance Mechanism and Company Size on Financial Distress

This study aims to examine the effect of corporate governance mechanisms and company size on the condition of a company experiencing financial distress. The indicators used to measure the corporate governance mechanism in the sample companies are the board of directors, the proportion of independent commissioners, managerial ownership, institutional ownership, and the audit committee. Meanwhile, financial distress is measured using a Springate model. This study uses secondary data from the entire population of mining companies listed on the IDX in 2016-2019. The sampling technique used purposive sampling. The analytical method used is ordinal logistic regression. The results of hypothesis testing show that the board of directors, the proportion of independent commissioners, the audit committee, and company size do not significantly affect the condition of the company experiencing financial distress. Meanwhile, managerial ownership and institutional ownership have a significant effect on companies experiencing financial distress.
Mechanism of thaumasite sulphate attack in cements, mortars and concretes

La thaumasite, Ca 6 [Si(OH) 6 ] 2 (CO 3 ) 2 (SO 4 ) 2 . 24H 2 O, est un produit de reaction de l'attaque de sulfate a basse temperature, dans des conditions favorables. Le compose complexe ne peut pas durcir. Pour sa formation, sont essentielles deux reactions, qui se produisent simultanement a des temperatures en dessous de 15°C. Elles sont tres lentes et se limitent aux systemes du ciment Portland. Au cours d'une des reactions, C-S-H est transforme immediatement, avec le carbonate et sulfate en presence d'ions calcium et d'eau. L'autre reaction demarre a partir d'ettringite prealablement formee, qui reagit ensuite avec C-S-H, sulfate et carbonate en presence d'ions calcium. Dans ce cas, l'ettringite est d'abord transformee en wood-fordite, un cristal mixte entre les extremites ettringite et thaumasite, et ensuite en thaumasite. Les deux reactions sont interdependantes, etant dans chaque systeme de ciment en concurrence pour les memes masses de C-S-H, carbonate et sulfate. Pour ces reactions il n'y a pas encore des donnee thermodynamiques. La formation de thaumasite aux basses temperatures et a pression normale peut s'expliquer par la necessite, de stabiliser suffisamment longtemps l'etat de mutation intermediaire, afin de permettre la formation des groupes [Si(OH) 6 ] 2- en configation stable, qui est favorisee par un changement de charge vers des groupes plans CO 2- 3 . Comme la thaumasite de possede pas de pouvoir liant, sa formation provoque des dommages sulfate. Quand la thaumasite se forme, elle est plus stable que l'ettringite. Elle se decompose a 110°C avec la formation d'une structure mal arrangee (verre de thaumasite), qui contient des tetraedres de SiO 2- 4 .
SE—Structures and Environment

Experiments were conducted in a full-scale, commercial greenhouse, to study the vertical distributions of temperature and humidity ratio under closed and naturally ventilated conditions. A comparison was made between ventilation by continuous roof openings only and ventilation by opening both roof and side windows. Two cases were considered for each of the ventilation modes: (i) the plants in the greenhouse were mature and big, and (ii) the plants were young and small. With mature plants, the gradients of temperature and humidity ratio before opening the ventilation windows were considerable and they remained so after the windows were opened (either roof only or both roof and side windows). Smaller gradients were observed with only roof ventilation, than with ventilation via roof and side openings. With young, small plants the gradients were much smaller than with mature plants and they could be assumed negligible for either ventilation mode.
Pupils with Special Educational Needs in Mainstream Schools from the Point of View of Their Peers: A Comparison of Experiences with Inclusive Education in Czech and Russian Primary Schools

ABSTRACT The paper presents the international research study conducted in selected Czech and Russian primary schools in 2020. This research was mainly focused on the issue of pupils’ relationships with their classmates with special educational needs, who are inclusively educated in regular school classrooms. According to the research results, the attitudes of pupils towards their classmates with special educational needs are rather neutral or even slightly negative in primary schools in both countries. However, most teachers do not consider this a problem affecting the classroom climate at all, and it seems that they do not work effectively with this issue as they are not skilled in this area and do not master the appropriate techniques used in support of pupils’ relationships and a quality classroom climate. Although there are some differences between the results in Czech and Russian primary schools, we can suggest the improvement in working with diversity, as well as the development of teachers’ skills for teaching heterogeneous peer group in a school classroom.
Computer simulation and human experiment on the Laplacian electrocardiogram (ECG)

The electrocardiogram (ECG) provides useful global temporal assessment of cardiac activity, but has limited spatial capabilities. Laplacian electrocardiogram (LECG) and body surface Laplacian mapping (BSLM), improvements over ECG provides high spatiotemporal distributed information about cardiac electrical activation. This project was divided into two parts: computer simulation and human experiment. In the computer simulation, a comparison of the performance of the tripolar and bipolar as well as spline LECG and BSLMs for localizing and imaging the cardiac electrical activation has been investigated. A simple planar surface model and a simplified eccentric heart-torso sphere-cylinder homogeneous volume conductor model were developed. Multiple dipoles with different orientations were used to simulate the underlying cardiac electrical activities. The three estimates of LECG and BSLMs were numerically computed from the induced electrical activity in the two models. For the human experiments, we designed and developed LECG tripolar concentric ring electrode (TCE) active sensors based on the finite element algorithm “nine-point method” (NPM). The active sensors were used in an array of six by twelve (72) locations to record bipolar and tripolar LECG from the body surface over the anterolateral chest.
Maternal and Cord Blood Signatures of Birth Weight: An Experience from Western India

Background : The thyroid status of mothers as well as neonates has a profound impact on neonatal brain development. Hypothyroidism at birth is one of the preventable causes of mental retardation in children. Low birth weight is an important cause of neonatal morbidity and mortality. Many factors responsible for low birth weight can be classiﬁed as fetal or maternal. Evidence-based interventions could save many newborns. For this, the knowledge has to be transformed into practice. Method : This study was performed at a medical college and tertiary care hospital in western India’s Thane district of Maharashtra. Eligible female participants were those who have enrolled in the hospital over 5 months from February through June 2021. All statistical analyses were performed using Mystat statistical software version 12.0 or Statistical Package of Social Sciences version 20.0 for Windows (IBM Corp, Armonk, NY). The normality of the data distribution was determined using the Kolmogorov-Smirnov test. Result : Maternal TSH and thyroxin are more than that of cord blood counterparts, while cord blood T3 levels were found to be more than maternal T3. Maternal TSH has a positive correlation with the birth weight of neonates. It shows a signiﬁcant negative correlation between the birth weight of cord blood T3 (r = -0.563) and Thyroxin (r = -0.510), respectively. The higher the maternal thyroxin and T3, the lower the birth weight. Conclusion : Present study shows the effect of thyroid status of mother and fetus both has an association with neonatal birth weight. More detailed analysis with sample collection as per trimester is required to know more about the impact of various confounding factors which have an impact on birth weight. Maternal TSH rather than thyroxin is a better predictor of neonatal birth weight.
High Quality Co-Sputtering AlScN Thin Films for Piezoelectric Lamb-Wave Resonators

Doped AlN thin films, especially high Sc-ratio AlScN film, have been reported to significantly improve the piezoelectric properties and draw attention for high performance resonators, transducers and integrated ferroelectric applications. However, many demonstrated devices were limited by poor film stress control, abnormal oriented grains and lack of a good etching profile. Compared to costly single alloy target, co-sputtered AlScN films can benefit customized doping concentrations and provide a unique solution for high Sc-ratio AlScN film quality and device studies. In this work, the optimized co-sputtering deposition and ICP etching processes of 500 nm AlScN thin film were developed and released AlScN Lamb-wave resonators were demonstrated. The influence of stress control by changing N2 process gas on the crystalline orientation, abnormal orientation grains, film roughness and piezoelectric property of AlScN thin films were discussed in detail. The AlScN film with a high Sc content requires a lower deposition pressure to obtain good crystalline quality. Al0.85Sc0. 15N thin films with FWHM of 1.75°, an average stress of −14.5 MPa and a stress range of 156 MPa were obtained. 130 nm/min etching rate and 77° sidewall profile were achieved by optimized ICP etching of Al0.78Sc0. 22N film. Lamb-wave resonators were fabricated based on both Al0.78Sc0. 22N and Al0.85Sc0. 15N thin films, achieving a quality factor of over 1000 at resonant frequency of approximately 300 MHz. The electromechanical coupling coefficients were improved by 152% and 80% compared to pure AlN devices. [2021-0210]
Impact of COVID-19 on the Integrated Master of Mechanical Engineering of the University of Porto

This paper focuses on the effect of the current COVID-19 global pandemic on the education system, namely on Mechanical Engineering courses offered at the Faculty of Engineering of the University of Porto. A brief description of the responsive measures adopted is presented regarding the necessary adaptations to distance learning because of law-enforced social distancing and public hygiene measures. Short surveys were answered by both students and faculty members to evaluate their opinion on this topic. Analogous questions on these surveys allowed for the direct comparison of their perspectives. A statistical analysis of students’ final marks on all lectured courses was also implemented, which provided insight as to whether distance learning and assessment methods have had significant impact on their performance. This study showed that the pandemic had a significant impact, affecting students and professors.
The Sleep-Obesity Nexus: Assessment of Multiple Sleep Dimensions and Weight Status Among Victorian Primary School Children

Purpose To examine the association between sleep and weight status across multiple dimensions of sleep (duration, efficiency, quality and timing) and assess the cumulative influence of these dimensions on the overall sleep-obesity association. Participants and Methods Cross-sectional data from 2253 students aged 8.8 to 13.5 years participating in two monitoring studies across regional Victoria was analyzed. Students were invited to have measures of height and weight taken and to complete a self-report electronic questionnaire on demographic characteristics and health behaviors. Logistic regression models were used to assess association between sleep dimensions and BMI z-scores. Results Beyond sleep duration, poor perceived sleep quality, delayed sleep initiation, later bed times and sleep-wake timing, all significantly increased the odds of overweight/obesity (OR 1.47, 95% CI: 1.07–2.01; OR 1.25, 95% CI: 1.02–1.55; and OR 1.70. 95% CI: 1.28–2.28, respectively). Additionally, a cumulative effect of having multiple poorly scored sleep dimensions was found, where four or more poorly scored sleep dimensions more than doubled the odds of overweight/obesity among children (OR 2.25, 95% CI: 1.41–3.58). Conclusion This study highlights the importance of measuring and considering multiple dimensions of sleep, along with the individual and additive influence of the sleep dimension on the sleep-obesity nexus.
Measuring Food Loss and Waste Costs in the Italian Potato Chip Industry Using Material Flow Cost Accounting

Material flow cost accounting (MFCA) represents an innovative tool to identify inefficiencies in the use of resources in agribusiness, measuring either mass flows or costs incurred along the entire supply chain. The purpose of the article is to estimate the meso-level ecological and economic impacts of food loss and waste in the Italian salty snack sector before and during the COVID-19 lockdown by applying MFCA. Furthermore, in the light of the European Commission Delegated Decision 2019/1597, it aims to assess whether MFCA is a suitable tool to support food waste management along the entire food supply, discussing implications for researchers, academics and managers, as well as for public authorities. The research explores potato chip production from the agricultural stage (either considering plant cultivation and harvest) to the final consumption stage. The functional unit is 1 ton of unpackaged chips produced. The Italian lockdown spurred an intense upsurge in snacking activities (i.e., the consumption of salty snacks), justifying the need to investigate an agri-food segment often overlooked from an economic, resources and waste management perspective. It emerges that the “chips system” generates production valued at EUR 461 million (78%) and costs associated with food loss and waste that exceed EUR 131 million (22%), revealing an economically important potential for savings through a reduction in undesirable negative material flows, or through the valorization of previously hidden material losses according to circular economy paradigms. This suggests that the company-level adoption of appropriate material and financial accounting systems could enhance both internal savings and collective benefits towards sustainable resources and waste management.
Clinical Characteristics and Pulmonary Computerized Imaging Findings of Critically Ill Egyptian Patients with Multisystem Inflammatory Syndrome in Children

Objectives. This study was carried out to delineate the patients’ characteristics and the imaging findings and their relation to some biochemical markers of 31 critically ill patients with MIS-C. Design. A retrospective cross-sectional study including all critically ill MIS-C patients admitted to the PICU from June 23rd to July 22nd, 2020. Results. Eighteen males and 13 females, with a median age of 9 years (interquartile range 6-11) presented mainly with fever (100%) and hypotension (100%). Abnormalities in the chest computed tomography were detected in 22 cases (71%). Consolidation and architecture distortion were detected in 58.1% of patients; bilateral lesions and lower lobe infiltrates, each, was evident in 64.5% of patients, while the peripheral distribution of lesions was seen in 71% of the cases. Pleural thickening and effusion, each, was found in 51.6% of the patients. In this small case series, the presence of high ferritin was significantly associated with the bilaterality of the lesions. Elevated C-reactive protein was associated with the peripheral distribution of the lesions. Thrombocytopenia and hypoalbuminemia were significantly correlated with the CT disease stage and CT severity score respectively. Conclusions. Although a few children in this group of MIS-C patients presented with respiratory manifestations, yet, most of them demonstrated significant radiological lung involvement, which necessitates a longer-term follow-up.
