The onslaught of COVID-19 has impacted all the spheres of life and caused the entire world to halt. The present study has attempted to investigate whether fear aroused by COVID-19 has raised e-governance adoption in the developing countries, specifically focusing on the rural regions. The study has utilized the learning from the protection motivation theory. The results show that COVID-19 has emerged as an unexpected thrust for e-governance adoption. The severity, vulnerability, response-efficacy, and self-efficacy components of protection motivation are found to have positive relationship with the attitude to adopt e-governance. The intrinsic and extrinsic rewards associated with not following the lockdown are found to have a negative relationship with the attitude to adopt e-governance. The response cost component of protection motivation is found to have an insignificant relationship with the attitude to adopt e-governance. The attitude is found to have positive relationship with the intention to adopt e-governance services.

Published: July 2021

This research proposed optimization models for task scheduling and sequencing in work-intensive multiple projects under normal and unexpected events. The objectives of scheduling model were minimizing the total overtime/under-time costs and maximizing satisfaction values on tasks due dates and processing standard times. Further, the sequencing model aimed to minimize the sum of tasks' start times, maximize resource utilization, and maximize satisfaction on project completion times. Illustrations of the proposed scheduling and sequencing optimization models were provided where the results showed effective scheduling and sequencing of project tasks at minimal costs and achieved the desired satisfaction levels on tasks and projects and significantly enhanced resource efficiency at minimal overtime and under-time costs. Further, optimization models were modified to deal with unexpected events. In conclusion, the proposed models may support project managers in planning project tasks in a cost-effective manner under normal and unexpected events.

Authors: Kurakin Artur I. , Strukov Ilya G. , Skoblikov Iakov P. , Karpov Vyacheslav M. , Efimov Evgeny I.
Published: July 2021

This paper presents studies about the influence of the surfacing mode on the formation of defects in the deposited metal produced by WAAM using Al-Mg alloy. As the main parameters that affected on the surfacing mode were the travel speed and the frequency of current pulses. Graphs about an influence of the travel speed on a size of pores and an influence the frequency of current pulses on a specific area of pores were constructed. It was concluded that with increasing of the surfacing speed, the size of defects decreased. Increasing the frequency of current pulses affected on increasing the specific area of pores. Changing the frequency of the current pulses leads to a change in the metal transfer. When using large-drop transfer metal, the defect concentration is minimal, but when using small-drop transfer, the arc stability decreases, which contributes to a higher pore concentration in the deposited metal.

Authors: Unyanin Alexander N. , Finageev Pavel R.
Published: July 2021

To predict the parameters of the quality of the processed parts and the period of durability of the cutting tool, mathematical models are needed that will allow us to calculate not only the mathematical expectation of the parameters of the machining process, but also the dispersion of these parameters. The working capacity of the tool and the quality parameters of the parts depend significantly on the temperature on the contact surfaces of the tool, as well as on the surface of the workpiece. Mathematical dependences for calculating the components of the total heat generation capacity during turning are given. It is assumed that the yield stress, which determines the cutting and friction forces on the contact surfaces of the cutter, workpiece and chip, depends on the temperature in the area of plastic deformation. The heat transfer at the boundaries of objects in contact with the process fluid or air is given in the form of the Newton-Richman law. The equations of thermal conductivity of contacting objects were solved together with the general boundary conditions in the contact zone, using the finite element method. The results of numerical simulation of the main component of the cutting force and temperatures in the contact zones of the face of the cutter with the chips and the fiank surface with the workpiece, depending on the yield strength of the workpiece material, are presented. The values of fluctuations in the cutting force and contact temperatures depending on the spread of the yield stress of the workpiece material during turning of workpieces made of 45 and 12X18H10T steels are determined. Based on the results of numerical modeling, regression equations are obtained for calculating the tangential component of the cutting force, the temperatures on the face and flank surfaces of the cutter, and the temperature on the surface of the workpiece.

Authors: Eremin Evgeniy N. , Yurov Viktor M. , Guchenko Sergey A.
Published: July 2021

In this work, a high-entropy alloy and CrZrTiNiCu coating were synthesized by mechanical alloying. It is shown that the microhardness of the CrZrTiNiCu coating is not inferior to and in most cases exceeds the hardness of high-entropy equiatomic alloys. The wear resistance of such a coating is 3·10-4 g/min, which also corresponds to special steels in terms of wear resistance. The high-entropy coating has a low coefficient of friction. It turns out to be antifrictional, which obviously leads to energy savings. For the first time, the surface energy, contact potential difference and work function of electrons for CrZrTiNiCu coating were determined.

Authors: Petropavlovskaya Victoriya , Novichenkova Tatiana B. , Petropavlovskii Kirill , Aleksandrova Olga V. , Fischer Hans Bertram
Published: July 2021

The paper shows studies of modified cement compositions with micro-filler. As such a micro-filler, an ash product is used - an activated waste of an ash-and-slag mixture. The enriched aluminosilicate waste is characterized by a fairly stable chemical and particle size distribution. The used activation of the ash product allows for a more dense packing of particles in the composition of the binder dispersed system. The high dispersion of the ash component requires additional plasticization of the dispersed system. Despite the fact that during the activation process the destruction of large-pore particles remaining after flotation occurs, the introduction of a plasticizer also improves the rheological characteristics of the compositions, and, consequently, increases the strength and density of the modified cement stone with the addition of a microfiller.

Published: July 2021

Acute suprarenal aortic occlusion, though rarely reported carries a high morbidity and mortality. Renal ischemia is one of the usual presenting features. Limb salvage and renal preservation depend on prompt diagnosis and management. A young patient with acute suprarenal aortic occlusion having renal failure and limb ischemia was managed with suprarenal thrombectomy and aortobifemoral bypass at our centre. Even though the presentation was delayed, renal functions were restored post procedure. This case highlights that renal revascularisation can be attempted in select cases with delayed presentation.
Lifesaving Successful Embolization of Aggressive Vertebral Body Hemangioma and a Large Pulmonary Arteriovenous Malformation
Authors: Pote Prashant Gajanan , Banode Pankaj , Rawekar Shishir
Published: July 2021

Vertebral hemangiomas are incidental finding and most of the time do not necessitate immediate attention unless symptomatic. Vertebral hemangiomas can be very aggressive to the extent that they can produce cord compression and paraplegia/paraparesis. Such cases need evaluation with magnetic resonance imaging to assess the cause, extent, and mass effect on the spinal cord. Transcatheter embolization and decompression surgery are well established modes of treatment as single or combined approach. Pulmonary arteriovenous malformation (AVM) is caused by the direct communication of main pulmonary artery with pulmonary vein, leading to a high-flow right-to-left shunt. This usually presents clinically as hypoxia, cyanosis, and dyspnea. The clinical signs and symptoms vary depending on the size, number, and flow of fistula as well as the associated vascular malformations. Transcatheter embolization is a treatment of choice for pulmonary AVM. However, this method may result in incomplete resolution if the malformation is large in size or supplied by multiple feeding arteries. Surgical resection may be considered in those kinds of cases. As AVM can lead to hemodynamical instability, these lesions need to be addressed first. In this case, pulmonary AVM came to notice post surgical decompression. Here, we report a case of aggressive vertebral body hemangioma and a large pulmonary AVM in the same patient, which were treated by embolization in two different settings.
Evolution of Patient Safety in Surgery
Authors: Tani Sobhana Iftekhar , Haldipur Nandan
Published: July 2021

Medicine since its inception has continued to evolve. The past few decades have seen many specialties branching out. This is been to the increasingly complex nature of the field consequent to advances in technology and understanding of the human body. In addition to advancing technology, there is a relatively recent focus on safety. Studies have shown that there are a significant number of errors with serious consequences that occur among surgical patients. Many of these errors are preventable. Several factors play a role which includes nontechnical aspects such as human factors. This is most evident in high-pressure complex situations such as an operating theatre. This prompted the World Health Organization (WHO) to take up global patient safety challenges. With the motto of “Safe Surgery saves lives,” the WHO has undertaken numerous regional and global initiatives to improve patient safety and pioneered the implementation of the surgical safety checklist. Patient safety has evolved as an important part of surgical practice. This article presents a brief narrative of the development of patient safety in the surgery, its expansion, and future direction.

Published: July 2021

Thoracic aortic aneurysm (TAA) is a dilation of the aorta of >150% of its normal diameter for a given segment. Weakening of aortic walls results in saccular, fusiform, or diffuse dilation. The incidence of TAA is about 10 for every 100,000 adults, with 20% being of familial origin. TAA carries a high risk of morbidity and mortality, with surgery and thoracic endovascular aortic repair being the definitive treatment. In this case report, we present an innovative approach for addressing concomitant coronary artery disease and TAA repair using double-arterial cannulation and differential hypothermic circulatory arrest without any postoperative neurological sequelae.
Venous Thromboembolism in COVID 19 Infection
Authors: Rao U Vasudeva , Wasim MD
Published: July 2021

The aims of this review are to ascertain the true prevalence of venous thromboembolism (VTE) in critically ill COVID 19 patients, to explore the strategy regarding prophylaxis and whether intensified prophylaxis is required for critically ill patients and to review the published guidelines to identify areas where clarity is required. An electronic search of the literature on VTE in COVID patients with reference to prevalence and prophylaxis was made using PubMed as the main search engine. A snowball search was followed to retrieve additional relevant data. The database consisted of prospective and retrospective studies and systematic reviews. The results showed that the reported incidence of VTE varies from <10% to more than 60%. Majority of studies reported a higher incidence of VTE in critically ill COVID 19 patients. Few authors, therefore, suggested a higher dose of low molecular weight heparin (LMWH), but this approach has not been validated. There is also a suggestion to extend the prophylaxis postdischarge. There are also reports of thromboprophylaxis with LMWH improves outcome in critically ill patients. This review confirms the generally held view that the incidence of VTE is higher in COVID 19 patients who are critically ill. However, whether they will benefit from a higher or intensified dose of Heparin is not fully assessed, with opinion equally divided among researchers there are few other grey areas like prophylaxis post discharge and in ambulatory patients.

Authors: Kwon Hyeong Mok , Kim Gyu Yeong , Shin Dong Hoon , Bae Young Kyung
Published: July 2021

Background: Cutaneous metastasis (CM) is the spread of cancer cells from a primary site to the skin and is rarely the first sign of silent cancer. We investigated the clinicopathological characteristics of CM from internal malignancies in Korean patients treated at our institution over 20 years. Methods: The clinicopathological findings of 112 patients (62 females, 50 males) with CM diagnosed at Yeungnam University Hospital between 2000 and 2020 were retrospectively reviewed. Results: Mean patient age was 58.6 years (range, 26 to 87 years), and the most common primary cancer site was breast (74.2%) in women and lung (36.0%) in men. Ninety-six patients (85.7%) presented with CM after primary tumor diagnosis. CM from the lung or biliary tract usually occurred within 2 years of primary tumor diagnosis, whereas metastases from the breast and kidney occurred several years later. The chest, abdomen, and scalp were common sites of CM. Breast cancer usually metastasized to chest skin, while gastrointestinal tract cancers commonly metastasized to the abdomen. The scalp was a common location for CM from various tumors. The most common dermatologic presentations were nodules and masses. Immunohistochemical studies helped identify underlying malignancies when primary tumors were unknown.Conclusions: The relative frequency of CM parallels the overall incidence of primary malignant tumors, and CMs usually occur at anatomic sites close to the primary tumor. CM can be diagnosed based on clinical, radiological, and histological features; however, immunohistochemical study is required in some cases.

used after the removal of lime using ammonium sulphate. In this study, the isolated
third fraction Fleshing Sludge (FS) from the hydrolyzed fleshing wastes used
fertilizer on the six different plants on growth commonly named Ghobi, Cran Dola,
Patunia, Placus, Dentist and Dalia. The observations were taken during 30 days of
incubation, at the usual temperature. The application of FS in plants observed that
growth was enhanced in significant proportion as compare to reference plants
supplemented with commercial fertilizer except in the Ghobi sample PS1 which
shows some phytotoxicity confirmed by leaf yellowing. The results revealed that the
applied sludge has no adverse effect on the growth of other experimental plants.
Results were taken by measuring plants according to standard methods

Authors: Vepa Vishnu Vardhan Reddy  , P.Sreenivasa Prasanna  , K. Thejomoorthy
Published: July 2021

A simple, Accurate, precise method was developed for the simultaneous estimation of the Levodropropizine and Chlorpheniramine in Tablet dosage form. The chromatogram was run through Ascentis C18 150 x 4.6 mm, 5m. Mobile phase containing Buffer Kh2po4: Acetonitrile was taken in the ratio 40:60was pumped through the column at a flow rate of 1.0ml/min. The buffer used in this method was Kh2po4. The temperature was maintained at 30°C. The optimized wavelength selected was260nm. The retention time of Levodropropizine and Chlorpheniramine was found to be 2.276min and 2.848. %RSD of the Levodropropizine and Chlorpheniramine was and found to be 0.7 and 0.7 respectively. %Recovery was obtained as 100.73% and 99.03% for Levodropropizine and Chlorpheniramine respectively. LOD, LOQ values obtained from regression equations of Levodropropizine and Chlorpheniramine were 0.14, 0.02, and 0.43, 0.06 respectively. Regression equation of Levodropropizine is y = 67089x + 5956.8 and y = 226526x + 13941 of Chlorpheniramine. Retention times were decreased and that run time was decreased, so the method developed was simple and economical that can be adopted in regular Quality control tests in Industries.
Estratégias de leitura: caminhos para autonomia leitora
Authors: Gonçalves Jaynne Kathleen Bueno , Sabatine Heloise Marques
Published: July 2021

Seguindo a conjectura de que a leitura é uma ação que deve ser ensinada e que contribui para a sensibilização, humanização e formação do leitor autônomo, este trabalho teve como base a mediação da leitura a partir das estratégias propostas por Girotto e Souza (2010), que contribuem para melhor compreensão do texto literário pelo aluno. Considerando que o ato de ler está presente na vida cotidiana e que neste processo o leitor apresenta trabalho ativo para a compreensão e interpretação do texto, como nos apresenta os PCN (1998), faz necessário o desenvolvimento de estratégias que contribuam para melhor desenvoltura do leitor na relação com o texto literário. O trabalho foi realizado com alunos do 7º ano do Ensino Fundamental, da rede pública estadual para a constatação das eficácias das estratégias no ato da leitura. As oficinas foram desenvolvidas tendo como base o conto ―Façanhas de Zé Burraldo‖, do livro Histórias de bobos, bocós, burraldos e paspalhões, de Ricardo Azevedo. Nas oficinas foram realizados discussões e registros escritos antes, durante e após a leitura, em que os alunos se utilizaram de conexões (texto-leitor, texto-texto, texto-mundo), inferências, visualizações, sumarizações e sínteses, sugeridas por Girotto e Souza (2010). Foi possível perceber o quanto essas atividades contribuíram para maior autonomia leitora e aumento de repertório literário, bem como o estabelecimento de relação significativa com o conto utilizado.

Authors: by PANLAR Global Rheumatology
Published: July 2021

"Aprincipios del año 2000, el Instituto de Medicina de los Estados Unidos publicó el resultado de una investigación realizada sobre los errores médicos en pacientes atendidos en forma hospitalaria. El informe titulado 'Errar es humano' concluyó que entre 44.000 a 98.000 personas morían anualmente en los hospitales de ese país como resultado de errores que sucedían en el proceso de atención, esta cifra se encontraba incluso por encima de la mortalidad producida por accidentes de tránsito, por cáncer de mama o por VIH en esa época. Desde entonces se han desarrollado y adoptado intervenciones altamente eficaces para evitar estos desenlaces relacionados con la seguridad de nuestros pacientes y ampliándolas más allá del ámbito hospitalario, incluyéndolas en la atención ambulatoria y, por supuesto, en el ejercicio reumatológico."
Classification is the Method of System Problems Detection
Authors: Lobanovsky Yury I.
Published: July 2021

It has been shown by historical examples that neglect of the basic system principles in creation or development of complex systems led always to problems, failures and/or disasters. System engineering techniques were used to build a common classificatory of system problems. Its structure have been validated and verified. No projects, events or processes have been identified that could not find its natural place in this classificatory. Classification of system problems helps to better understand the reasons why complex systems are not able to perform the tasks assigned to them.
Corruption, Ritualism and Prophetic Role of the Catholic Church
Authors: Aryanto Antonius Galih Arga , Lelono Martinus Joko
Published: July 2021

This interdisciplinary study attempts to relate corruption with the Catholic Church's role as the moral and social critics that compel believers to participate in confronting corruption and bribery. The interdisciplinarity is also the method applied in the study. It includes an exposition of the economic data of the GDP, its theological interpretation based on the story of Naboth and the king in the Old Testament, and strategic action field theory. The article begins with widespread corruption in ASEAN, then continues with a theological foundation for believers’ role as guardians of moral and social values. The Church, however, faces ritualism and religious formalism that cause faith values do not influence to eradicate corruption. Finally, by implementing the social study of Strategic Action Field (SAFs) theory, the paper proposes an anti-corruption movement as a strategic action for the Catholic Church to tackle corruption. The study found that the social study of Strategic Action Field (SAFs) theory allows the Church to develop the anti-corruption movement as the strategic action to create pastoral works to tackle corruption
