Authors: Sahoo Jyoti Prakash , Goutam Siddhartha 
Published: August 2022

Abstract
Introduction: Mental health illness has increased substantially since the COVID-19 pandemic. Estimating anxiety and depression in healthcare providers can clarify the dimensions of this burden. The objectives of the study were to compare the levels of anxiety and depression in the study population (COVID-positive versus COVID-negative) with Hamilton's anxiety (HAM-A) and Hamilton's depression (HAM-D) scales, respectively, and to estimate the relative risk of anxiety and depression in the COVID-positive participant to COVID-negative participant with subgroup analyses as per gender and occupation.Materials and Methods: In this cross-sectional study, we recruited 983 healthcare professionals from SCB Medical College, India, to assess their levels of anxiety and depression during the COVID-19 pandemic. We compared the HAM-A and HAM-D scores of COVID-positive and COVID-negative participants. We also calculated the relative risks of developing anxiety and depression symptoms. We used R software (version 4.1.2) for the statistical analyses and generation of plots. Results: The mean age of the study population was 35.95±11.54 years. Six hundred thirteen participants (62.36%) were positive for COVID infection. 575 (58.49%) persons had anxiety, as suggested by their HAM-A scores. The majority of them were nurses and pharmacists (245, 24.92%), followed by students (236, 24.01%) and clinicians (94, 9.56%). 620 (63.07%) persons had depression. Most of them were medical students (301, 30.62%), followed by nurses and pharmacists (211, 21.46%) and clinicians (108, 10.99%). The COVID-positive individuals were less anxious [relative risk: 0.614; 95% CI: 0.538-0.701] and more depressed [relative risk: 2.541; 95% CI: 2.079-3.106] than the COVID-negative individuals. Subgroup analysis of the HAM-A and HAM-D scores yielded similar results.Conclusion: The majority of the study population had symptoms of anxiety and depression during this pandemic. The COVID-negative individuals were more anxious than the COVID positives. Nevertheless, the symptoms of depression were more common in COVID-positive individuals.

Abstract
The influence of aeration time and concentration of sodium silicate (Na2SiO3) in the cultivation of the microalgae Nannochloropsis oculata was studied. Aeration pumps were turned off for 2, 4, and 6 h, while cells were exposed to Na2SiO3 at concentrations of 40.0, 50.0, and 60.0 g.L− 1 under constant artificial lighting. It was observed that cell growth and bio-oil production were dependent on Na2SiO3 concentration but not on aeration time. Cellular density of 132.104 cel. mL− 1, and about 15% of oil yield were obtained.

Published: August 2022

Abstract
High strength steel plates with doubly curved surface in small batch have been widely applied in shipbuilding, aerospace, automobile and other manufacturing fields to meet the lightweight market demand. To achieve the doubly curved high strength steel plates with smaller forming force, the multi-point incremental bending process was proposed. In addition, to deform the high strength steel Q345B plates efficiently and accurately, the tools’ loading path strategy under the minimum strain energy field (that is, along the principle curvature direction) with considering the springback height was proposed. In this paper, the influence of single point bending-springback characterization at different bending positions and that with different incremental bending depths are analyzed based on experiments and numerical simulations to finally determine the whole springback height distribution for the entire high strength steel plate. Then the high strength steel plate with target doubly curved surface was deformed experimentally by the multi-point incremental bending experiments based on two kinds of tools’ loading paths according to whether considers the springback height of the high strength steel plate. The maximum loading forces and the absolute shape error were compared and analyzed. Results validated the reliability of the multi-point incremental bending experiment along the principle curvature direction with considering the springback height and the paper also puts forward the following up to be improved for the flexible incremental bending process in the future.

Published: August 2022

Abstract
Objective: Our study was aimed to understand the importance of FA-BRCA pathway genes in cervical carcinogenesis and their association with the prognosis of the disease. Material and methods: we analysed the molecular profiles of the key regulatory genes of FA-BRCA pathway (BRCA1, BRCA2, FANCC, FANCD2) in 109 cervical lesions at different clinical stages and validated in different bioinformatical analysis as well. The results were next correlated with different clinicopathological parameters. Furthermore, the drug tolerance mechanism of the genes was characterized by treating two CACX cell lines (SiHa and HeLa) in presence of the chemotherapeutic drug cisplatin. Result: Our data showed that the expression pattern (mRNA/Protein) of the genes of FA-BRCA pathway was gradually decreased from normal cervical epithelium to the development of carcinogenesis, also validated in different GEO datasets. Further, in-depth look into the results revealed that genetic (deletion) and epigenetic alterations (promoter methylation) [30 to 55 %] of the genes was strongly correlated with their reduced expression and development of cervical cancer among the patients, resulting in worst 5-year overall survival trend. Incidentally, the prevalence of promoter methylation in both plasma and respective tumour DNA of invasive cervical carcinoma patients implicated its prognostic importance and association with disease recurrence in this study. In continuation of that, our in-vitro study revealed that cisplatin could upregulate the FA-BRCA pathway genes gradually with increasing drug concentrations in the CACX cell lines through promoter hypomethylation due to reduced expression of DNMT1, indicating the intrinsic mechanism of drug tolerance of residual tumour cells of the disease.Conclusion: Our data showed that the inactivation of FA-BRCA pathway was associated with the development and prognosis of CACX. Up-regulation of the pathway genes in presence of cisplatin in the CACX cell lines suggested a plausible mechanism of non-responsiveness to the therapy.

Published: August 2022

ABSTRACT

Objectives
To compare mandibular incisor root volume change (RVC) after 6 months between an anterior bite plane fabricated from acrylic resin (ABP) and thermoplastic materials (TBP) in a group of growing patients.

Materials and Methods
Thirty-four deep bite patients (age: 11.57 ± 1.30 years) were randomized into the ABP or TBP group. The RVC from before treatment (T0) to 6 months after treatment (Tct) at the labio-coronal (La1), labio-middle (La2), labio-apical (La3), linguo-coronal (Li1), linguo-middle (Li2), and linguo-apical (Li3) segments were investigated from cone beam computed tomography (CBCT) images. Cephalometric changes between T0 and the visit that normal overbite was achieved (Tcep) were also assessed (α = 0.05).

Results
Thirty-four patients completed the trial. Treatment duration was 5.0 ± 2.9 months. Significant decrease in root volume (RV) was found at the La2, La3, and Li3 segments of the ABP group (P &lt; .05). No significant RVC was found in any segment of the TBP group (P ≥ .05). Comparing between groups, the RVC at La3 and Li3 of the ABP group was significantly greater than that of the TBP group (P &lt; .05). However, total RVC between groups was not significantly different (P ≥ .05).

Conclusions
Growing patients undergoing deep bite correction for 6 months with ABP displayed more apical RVC of mandibular incisors than those who used TBP. However, total RVC between appliances was not significantly different.

Background: Despite the technological advances the zygomatic implants (ZI) and its proven success, this rehabilitation option is sensitive, not a routine in dental practice, requiring technical mastery, surgical experience, and in-depth anatomical knowledge, which makes it quite susceptible to complications. In addition, little is discussed about these disorders, whether immediate or late, although they are essential knowledge for the surgeons who perform this procedure. Aim: The objective of the study was to answer the question through literature review: "Are there surgical complications in zygomatic implants?" As well as to argue the main intercurrences found. Material and Methods: The review of the literature was conducted on PubMed/Medline, Cochrane and SciELO using the descriptors: “Complications” or “Failure” and “Zygomatic Implants”. The included articles were observational studies that related ZI and complications. The initial research identified 448 articles, but 42 of them that mentioned complications associated with ZI were considered in this study. Results: The most common complication is sinusitis followed by peri-implantitis, problems with the prosthetic connection, fistula towards the implant, paresthesia, hematoma, lip laceration, ecchymosis, penetration of the orbital cavity, aspergillosis, intracranial penetration, and intraorbital hemorrhage. 44 out of 2835 ZIs placed in immediate or late loading were lost (1.5%). There were 223 minor or major complications in the 2827 implants (7.86%). Conclusions: The low morbidity of this treatment for maxillary atrophy, there are some immediate and late complications to be considered in the choice of rehabilitation treatment and that these should be reported preoperatively to the patients.

Terdapat hubungan jangka panjang untuk peubah-peubah yang ada dalam persamaan kointegrasi pertama terhadap perubahan inflasi yaitu inflasi, kurs dan ekspor pada satu periode sebelumnya. Terdapat hubungan jangka panjang untuk peubah-peubah yang ada dalam persamaan kointegrasi kedua terhadap perubahan inflasi yaitu impor, kurs dan ekspor pada satu periode sebelumnya. Catalbas' research (2016) was modified in this study by adding an inflation variable. Vector Error Correction Model (VECM) is used in this study to predict variables. This study aims to model the exchange rate, inflation, imports and exports, forecast exchange rates, inflation, imports and exports, and determine the long-term relationship between variables. The inter-variable model in this study is VECM with a lag of 2, using a deterministic trend assuming none intercept no trend, and there are 2 cointegration. This research model is said to be good for predicting exports and imports with a tolerance limit of 5%. Based on the VECM, it is found that there is a long-term relationship for the variables that exist in the second cointegration equation to changes in imports, namely imports, exchange rates and exports in one previous period. There is a long-term relationship for the variables in the first cointegration equation to changes in inflation, namely inflation, exchange rates and exports in the previous period. There is a long-term relationship for the variables in the second cointegration equation to changes in inflation, namely imports, exchange rates and exports in the previous period.

Published: August 2022

Celem artykułu jest prezentacja sposobów opisywania różnorodności i wielokulturowości w serii Detektywi na kółkach Marcina Kozioła. Seria ta składa się z trzech książek: Skrzynia Władcy Piorunów (2014), Tajemnica Przeklętej Harfy (2017) oraz Gwiazda Blachonosego (2020). Autorka wychodzi od problemów związanych z reprezentacją różnych systemów wartości i kultur we współczesnej Polsce, w tym braku widoczności poszczególnych typów różnorodności (takich jak odmienna od dominującej religia czy nieneurotypowość). Następnie przechodzi do analizy różnych aspektów wielokulturowości w serii Kozioła. Na podstawie tych analiz można stwierdzić, iż sposób ujęcia różnorodności społecznej w tych trzech powieściach stanowi etap pośredni między tradycyjnymi przedstawieniami tego tematu a wrażliwością czytelników XXI wieku.
Moving robotics competitions virtual: The case study of RoboCupJunior Soccer Simulation (SoccerSim)
Authors: Martins Felipe N. , Matejov Adrián , Šuppa Marek 
Published: August 2022

For almost 25 years, the goal of the RoboCup has been to build soccer robots capable of winning against the FIFA World Champion of 2050. To foster the participation of the next generation of roboticists, the RoboCupJunior competition takes place in parallel and provides a similar challenge of appropriate difficulty for high school students. RoboCupJunior has three main categories: Soccer, Rescue and OnStage. For the Soccer category, participants need to design, build and program a team of autonomous robots to play soccer against an opponent team of robots. The competition is physical in nature, since it assumes physical robots playing against one another. In 2020 and 2021, the COVID-19 pandemic has made it difficult for a competition of this type to take place, due to obvious restrictions on physical gatherings. To allow for some sort of participation, and inspired by positive experience of the larger RoboCup community, the Organizing Committee of RoboCupJunior Soccer has explored porting a portion of the challenge to a simulated environment. Many of the existing environments, however, are built for higher education/research teams competitions or research, making them complex to deploy and generally unsuitable for high school students. In this paper we present the development of SoccerSim, a simulated environment for RoboCupJunior Soccer, based on the Webots open-source robotics simulator. We also discuss how the participation of students was key for its development and present a summary of the competition rules. We further describe the case study of utilizing SoccerSim first as a testbed for a Demo competition, and later as part of RoboCup Worldwide 2021. The participation of more than 60 teams from over 20 countries suggests that SoccerSim provides an affordable alternative to physical robotics platforms, while being stable enough to support a diverse userbase. The experience of using SoccerSim at RoboCupJunior Worldwide 2021 suggests that a simulated environment significantly lowers the barrier to entry, as evidenced by the participation of many teams that have not participated before. To make it easy for similar competitions to take place in the future, we made the code of SoccerSim available as open-source, as well as the associated tooling required for using it in a tournament.
