A quadrilateral flat-shell element for the static and dynamic analysis of composite and sandwich cylindrical, spherical and conical shell panels
Authors: Dagade Vaishali Atulkumar , Kulkarni Shripad 
Published: May 2022

Abstract
A quadrilateral flat-shell element is developed for analysing the deflections, stresses and natural frequencies along with their allied mode shapes of cylindrical, spherical, and conical shell panels made up of layered composite and sandwich material. The developed element (DKZigTS1) is based on zigzag theory and has seven local as well as global DOF per node. The concept of obtaining transformation matrix is used for transforming actions and reactions from local to global direction to convert the plate bending into a flat-shell element. The two separate coordinate systems are used to transform rotational and translational degrees-of-freedom (DOF), from local to global direction. The local translational DOF are transformed to global Cartesian coordinates (x, y, z) and the local rotational DOF are transformed to the surface coordinate system (ξ
1, ξ
2, ξ
3), in which ξ
3 is perpendicular to the surface. The DKZigTS1 element gives fairly accurate results that align with the 2D analytical and the 3D elasticity solutions, reported in the literature for moderately thick and thick shell panel. The present results are also in good agreement with the 3D finite element solutions for shallow and deep shell panels having various material properties, boundary restrained environments, and geometrical shapes considered in this study.

Published: May 2022

Abstract
Free Space Optics (FSO) is one the most in-demand technology, and is used indoors, on the ground, in space, and even underwater. It is used to broaden communication access to places where bandwidth is insufficient or where difficult topography prevents the use of cable communications. One of the foremost communication challenges that contribute to the degradation of FSO performance is the environmental condition. Hilly regions experience heavy rainfall and have rough terrain which may demean the FSO link communication. In this work, for real-time rain rate analysis of the Meghalaya region two unique rain attenuation models are investigated for monsoon months from the years 2014 to 2020. Considering Marshall and Palmer’s model and by employing 8, 16 and 32-quadrature amplitude modulation (QAM) schemes, radio-over-free space optical (RoFSO) system has been evaluated by varying FSO channel range, power and bit rate.

Zusammenfassung
Gesundheitskompetenz ist der Grad, zu dem Individuen durch das Bildungs-, Sozial- bzw. Gesundheitssystem in die Lage versetzt werden, die für angemessene gesundheitsbezogene Entscheidungen relevanten Gesundheitsinformationen zu finden, zu verarbeiten und zu verstehen. Individuelle Fähigkeiten dürfen nicht die Voraussetzung sein, in einem komplexen Gesundheitssystem zurechtzukommen, sondern es ist vielmehr das System, das der Komplexität der Menschen gerecht werden muss.
Participatory viewers’ engagement with the dual translation problem on the danmu interface: a social semiotic case study
Authors: Yuhong Yang 
Published: May 2022

Abstract
This article looks at participatory viewers’ engagement with foreign language video contents facilitated by the danmu interface on a video-sharing website in China. Using the video of the Chinese athlete Sun Yang’s public hearing hosted on Bilibili as a case study, this article investigates Bilbili users’ danmu-based translational efforts and their engagement with the translation problem inherent in the hearing through multimodal discourse analysis, with supportive analysis of individual users’ danmu footprints from a diachronic perspective. Danmu-based viewer activities are approached from the social semiotic perspective and situated in the distribution stratum of the communicative practice of video sharing, with a view to understand participatory viewers’ meaning making processes in their consumption of videos on the danmu interface. The findings show a manifest willingness from participatory viewers to engage with the dual translation problem specific to this case, who submit different kinds of translational inputs onto the video frame in response to the untranslated video and articulate translation-related discourses as prompted by the inherent translation problem in the video. This study contributes to social semiotic discourse analysis of danmu-mediated communication as well as to non-professional translation studies through a focus on novel translation practices emergent in the Chinese context of participatory viewing.

Published: May 2022

The Business-to-Business Meeting Scheduling problem consists of scheduling a set of meetings between given pairs of participants to an event, while taking into account participants’ availability and accommodation capacity. A crucial aspect of this problem is that breaks in participants’ schedules should be avoided as much as possible. It constitutes a challenging combinatorial problem that needs to be solved for many real world brokerage events.
In this paper we present a comparative study of Constraint Programming (CP), MixedInteger Programming (MIP) and Maximum Satisfiability (MaxSAT) approaches to this problem. The CP approach relies on using global constraints and has been implemented in MiniZinc to be able to compare CP, Lazy Clause Generation and MIP as solving technologies in this setting. We also present a pure MIP encoding. Finally, an alternative viewpoint is considered under MaxSAT, showing best performance when considering some implied constraints. Experiments conducted on real world instances, as well as on crafted ones, show that the MaxSAT approach is the one with the best performance for this problem, exhibiting better solving times, sometimes even orders of magnitude smaller than CP and MIP.
Accounting for ESG Risks in the Discount Rate for Business Valuation
Authors: Захматов Дмитрий , Вагизова Венера , Валитов Гаяз 
Published: May 2022

The research is aimed at developing tools for determining and justifying specific ESG risks for the purpose of accounting for projected cash flows in the discount rate in business valuation. A study of modern methods, standards and publications in this area has been conducted, and the need for their refinement and development for practical use has been determined.
The research used the results of the works by foreign and domestic authors, as well as their own professional experience. The authors used general scientific methods of cognition, such as classification, logical and system analysis, typology and generalization.
The proposed tools are aimed at substantiating, supplementing and clarifying the discount rate model (CAPM) by introducing additional coefficients that take into account the influence of ESG factors. The article proposes a scoring model for assessing risks on a point scale and tools for their subsequent translation into correction coefficients using the method of expert assessments, which already allow them to be applied in practice today. The model of accounting for specific risks is based on data from literary sources, and demonstrated using a practical example.
The author’s tool is designed to provide analysts, appraisers and experts with a qualitative justification and calculation of specific risks associated with ESG factors when evaluating a business. It is also assumed that the proposed tools will serve as one of the criteria for managing business value, allowing for measures to reduce specific risks and increase company capitalization.
Remodeling of the bioelectric activity of the brain in the outcome of cortical resection
Authors: Astakhova Ekaterina A. , Marchenko Elena V. , Chukhlovin Alexander A. , Aleksandrov Mikhail V. 
Published: May 2022

Background: The total scalp electrorencephalography shows the activity of groups of cortical neurons. But each of these groups does not exist in isolation, but they are influenced by other areas, both cortical and subcortical systems of the brain. In the course of neurosurgical treatment, patients underwent resection of cortical areas in which the epileptiform focus was located. In patients with resection of the temporal lobe with structural drug-resistant epilepsy, EEG patterns of loss of activity are not recorded above the remote areas.
Aim: to study the mechanisms underlying the formation of electrorencephalography patterns recorded in the projection of the resected temporal lobe of the brain in patients operated on for focal drug-resistant epilepsy.
Materials and methods: There were examined 22 patients with structural pharmacoresistant epilepsy. Coherent analysis of the electrorencephalography was performed for an epoch of 30 seconds in transverse and longitudinal intrahemispheric pairs of leads.
Results: Correlation interactions between the temporal leads and their surrounding areas are enhanced after removal of the temporal lobe involved in the epileptic system.
Conclusion: The activity recorded in the postoperative period in the projection area on the scalp of the resected area is formed as a result of signal transmission from other departments.

Published: May 2022

Background: Dichorionic diamniotic twin pregnancy resulting from IVF can lead to isthmic-cervical insufficiency with concomitant complications. Against the background of the initial genital chronic infection in a woman there is a threat of septic complications for the mother-fetal couple. The complex pathology is accompanied by an accumulation of toxic substances in the mother-placenta-fetus system that requires pathogenetic treatment measures.
Clinical Cases: This paper presents data on the results of efferent therapy in two pregnant women with dichorionic diamniotic twin pregnancy complicated by fetal bladder prolapsing into the cervical canal up to the external pharynx (1 case) and with premature amniotic fluid outflow of the first fetus (2 cases). The patients received preserving therapy at the hospital and then were transferred to the perinatal center with the clinical signs of threatening abortion, endotoxemia, and moderate inflammatory response, which were treated with efferent therapy in the form of medium-volume membrane plasmapheresis combined with photodilution with ultraviolet and laser beams. There were no complications during efferent therapy. In 1 and 2 observations the pregnancies of women in the perinatal center were prolonged by 45 and 34 days with operative delivery at 27 and 31 weeks, respectively. There were no septic complications in women and children. The newborn premature infants after therapeutic and rehabilitative measures had good prospects for a full life.
Conclusion: The efferent therapy methods are safe and, in cases of IVF-infant foetuses with complicated isthmic-cervical insufficiency, are a pathogenetic measure; they help to prolong pregnancy and prevent infectious complications in the mother and fetus.

Published: May 2022

Blood smear is considered as the gold standard test to diagnose Malaria parasite. The newer RDTs (malaria antigen) are reported to be highly sensitive, specific and time saving as compared to other diagnostic modalities. This test is undertaken to compare the efficacy of PfHRP-2 tests, PLDH and manual technique. A total of 252 cases of malaria as diagnosed by Composite reference techniquewere studied. The sensitivity of TFM, RDTs and PCR is 71.5%, 84.3% and 82.6% respectively and the specificity is 81.9%, 77.2% and 78.2% respectively.: The fact that the PCR & RDTs are costly, cannot assess the response of patients to treatment and inability to assess parasitic stage and density, makes the old dictum “Blood smears are the gold standard for the diagnosis of Malaria” to still hold truth.

Serum adenosine deaminase activity is associated with coronary artery disease.The present work was done to understand the relation of serum adenosine deaminase activity with dyslipidemia in ischaemic heart disease.This cross-sectional study comprised 200 subjects; healthy and myocardial infarction. Serum ADA and lipids were estimated. Obtained data was statistically analysed.Increase in serum ADA activity correlating with dyslipidemia was found in Myocardial infarction subjects.Increased ADA has role in LDL oxidation, dyslipidemia, foam cell transformation etc. leading to atherosclerosis and ischemic heart disease. Adenosine deaminase has a crucial role in the evolution of ischemic heart disease through dyslipidemia and coronary artery disease.
A study of splanchnic vein thrombosis in cases of acute pancreatitis and its outcome in a tertiary care center
Authors: Chandrashekar S 
Published: May 2022

Splanchnic veins thrombosis(SVT) is one of the rare but known complications of Acute Pancreatitis(AP). It mostly involves Splenic vein(SPV), Superior mes enteric vein(SMV) and often Portal vein(PV) either individually or in combination. Though the cause is thought to be multi-factorial, a direct inflammatory process is implicated in the pathogenesis of SVT in AP. SVT can be sometimes an incidental finding in the radiological evaluation, but it also presents with severe pain, portal hypertension, hepatic dysfunction and bowel ischemia in a life-threatening scenario. Present study aims at understanding incidence, pattern, therapy initiated, complications and outcome of SVT in AP.A serial study of 89 cases of acute pancreatitis who underwent Contrast Enhanced Computed Tomography was conducted at tertiary care centre, department of general surgery, Mysore Medical College and Research Institute, Mysore, Karnataka from the period of January 2021 to June 2021. Out of 89 cases studied, 62 were male, 27 were female with mean age of 39.5 years. Most common cause of AP was Ethanol abuse, followed by Gallstones, Main pancreatic duct (MPD) anamoly, Anamoly of duodenal papillae and idiopathic. 37(41.57%) Patients had SVT. 31(83.78%) were male, 6 (16.22%) were female. 29 patients received anti-coagulation therapy, out of which 24 showed good response. Out of 8 patients who didn’t receive therapy 3 showed reduction in size of clot by 75%. Hence, anticoagulation has a therapeutic role in treatment of SVT (p- 0.0157). SVT is one of the known complications in AP with increase in incidence severity and with presence of peripancreatic collection. Spontaneous resolution of SVT is seen in about 40% of patients whereas anticoagulation therapy has a good role.

The perforated part along with the tumour was resected and histopathological examination revealed that the tumour was gastrointestinal stromal tumour. Postoperatively the patient received Imatinib.Traditionally, the prognostic factors of these tumours are mitotic rate, tumour size and anatomic site. The complete surgical resection and use of Imatinib are the best approach.
Inter thenar skin sparing carpal tunnel release- role of incisions and endoscope - A case report
Authors: Mashalkar Narendra.S. 
Published: May 2022

Endoscope in plastic surgery has played a role, wherever minimal scarring is required. An attempt to decrease the length of scar is one of the priorities of a surgeon, as this brings down the chance of scarring, pain and associated morbidity, with decreased hospital stay. Hand is an organ with intricate anatomy and many vital structures are densely packed in hand. This makes the available space scarce for another instrument to add into the hand. Hence endoscopic intervention in hand is negligible. The margin of error also remains negligible in hand, as it would compromise on the function of hand, which is an absolute necessity. Aesthetic appearance of hand is not as important as function; nevertheless if possible, one should also consider giving an aesthetic scar with good function of hand and these criteria will be the goal for any hand surgeon.

Published: May 2022

The COVID-19 pandemic created the need for a global change in tertiary education. Universities that traditionally relied on contact with students in physical classrooms were forced to consider modes of remote teaching to mitigate the risks of infection due to physical proximity. This study evaluates the emergency remote teaching implemented within the Department of Information Technology at the Durban University of Technology, South Africa. An emergency remote teaching model with four stages consisting of: preparation, synchronous and asynchronous teaching and learning, e-assessments and reflections are described, analysed and evaluated with reference to both lecturers and students. The evaluation is performed using both qualitative and quantitative research methods. Qualitative analysis was performed on 29 sources using content analysis. 229 initial codes were identified and first categorized into 13 subcategories and finally to the four categories synonymous with the adopted four-stage emergency remote teaching model: preparation (135 references), asynchronous and synchronous teaching and learning (67 references), e-assessments (25 references) and reflections (8 references). Quantitative data on the use of the learning management system from 2019 to 2020 evaluated the results of the applied changes in practice. From the results, it was evident that students and lecturers invested much time in the learning management system with 13 tools being adopted by the 49 analysed subjects. The learning management system was used extensively for communication, assessment and dissemination of subject content. The comparative results of the data from the 2019 and 2020 academic years showed that the majority of the 2020 subjects’ final results were statistically higher than the 2019 results. Results of analysis revealed the success of the implementation of the four-stage emergency remote teaching model.

Revealing invisibility: Interpreting social and behavioral aspects of the Coronavirus pandemic through student documentary photography
Authors: Jirásek Ivo , Stránský Bohuslav 
Published: May 2022

Life for the population in the Czech Republic came to a standstill in spring 2020 due to measures enacted in relation to the Coronavirus epidemic: a travel ban and closed borders, the cancellation of physical lessons at all types of school, the closure of stores except those securing basic necessities, radical restrictions to free movement of people. This unprecedented situation became the inspiration for creative work by students at the Studio of Advertising Photography at Tomas Bata University in Zlin. Since joint work in the studio was not possible, the students were given their assignments as part of the Digital Photography classes in the form of a document reflecting the social situation during the Corona crisis. Selected visual narratives, or photo novellas, are a methodical component of arts-based research, meaning the use of art artefacts and imagination for a more complete knowledge of this mode of social reality. Verbal commentary complements the images’ topic by interpreting the main themes of the selected photographic images: Easter festivities without religious services, sewing facemasks and covering faces, newly discovered meanings of borders and emptiness, the social role of meals in family life. The Coronavirus crisis has revealed the hidden opportunities of a new way to see and discover again how to evaluate our everyday life, something which in the haste of each ordinary day can become subconscious routine.

Response of Nutrients Spray on Physiological and Biochemical Aspects of Seed Quality in Mungbean [Vigna radiata (L.) Wilczek] during Summer
Authors: . Shivani , Jakhar S.S. , Kumar Sunil 
Published: May 2022

Background: Mungbean is considered as one of the most important pulse crop that belongs to the family of leguminosae. Seed is a basic input and vital element that plays a crucial role in agriculture production as well as in the national economy. Good quality seed gives high yield and higher biomass, which ultimately increases farmers’ income. Methods: The investigation was performed at the laboratory and research farm of Department of Seed Science and Technology, CCS HAU, Hisar during the summer season 2020, which consists of foliar application of nutrients at the first fortnight after sowing of the crop i.e., water spray @ 550 L/ha, urea @ 1%, urea @ 2%, NPK (18-18-18) @ 1%, NPK (18-18-18) @ 2%, zinc sulphate + urea @ 2% + 0.5%, SOP (00-00-52) @ 2% and urea phosphate (17-44-00) @ 2% along with control (untreated) on mungbean varieties (MH-421 and MH-318). The harvested seeds were evaluated for physiological and biochemical parameters of seed quality. Result: The seed quality parameters (physiological parameters i.e., germination, seedling length, seedling dry weight, vigour indices and biochemical parameters i.e., peroxidase, superoxidase and dehydrogenase activity) were recorded higher when the foliar application of NPK (18-18-18) @ 2% was done in both the varieties.
