Published: January 2024

Resume. To develop a mathematical model of the interaction of a carbide steel coating with a steel base under conditions of the formation of a liquid phase.Methods. The average value of the transition zone was experimentally determined using a PMT-3 device. The size of the transition zone in the carbide steel layer was determined using a MAR-2 X-ray microanalyzer.Results. A mathematical model of the interaction of a carbide steel coating with a steel base under conditions of liquid phase formation has been developed. It is established that the distribution of carbon in the transition zone of the carbide steel layer (δL) and the steel base (δS) is described by an exponential dependence, and the above technique allows to predict the size of the transition zone with high accuracy, which confirms the corollary of the theory that when applying a layer on a base with a lower carbon content, the width of the transition zone will be greater, and the speed of the melting of the base is less. properties of coatings made of carbide steels of various compositions. High adhesion strength of coatings to the substrate after vacuum sintering has been established (for carbide steel of 10% TiC, steel Cr6V3Mo 116 MPa; for carbide steel of 40% TiC, steel Cr6V3Mo 131 MPa; for carbide steel of 40% TiC, steel Cr12Mo 220 MPa), which in combination with their high physical-mechanical properties allow us to recommend the method of plasma spraying of coatings made of carbide steels for the restoration of worn surfaces of parts and tools for various purposes.Conclusion. The developed mathematical model makes it possible to calculate the size of the intermediate layer, as well as the diffusion coefficients of carbon in the liquid phase and in the steel base.

Web-based online exhibition using immersive technology, namely Virtual Reality & Augmented Reality, has a major effect on the efficiency of time, place, and cost in providing visitors with an understanding of building architecture. Interaction in understanding architectural modeling is also assisted by a technology called Avatar Mediated Communication (AMC) which is the scope of interaction with other visitors in a Virtual Environment created by Virtual Reality technology. Technology that is able to support all website-based reality activities is made with the Laravel & Express Js framework (Website), Spoke Mozilla Hubs (Virtual Reality Environment), and Library AR Js (Augmented Reality Marker Based). The technology is selected, built, and combined in the stages of the Research & Development (R&D) method, the Multimedia Development Life Cycle (MDLC) model in examining the development stages and user responses to web-based Virtual & Augmented Reality development products. The results of the responses obtained are based on 6 categories in the UEQ (User Experience Questionnaire) instrument. The result showed that the three largest categories that give a positive response are stimulation, attractiveness, and novelty. Meanwhile, the three categories below are efficiency, perspicuity, and dependability. This indicates that the online exhibition in the support of immersive visualization is able to increase user curiosity in trying to enter the virtual reality room presented in web-based Virtual & Augmented Reality.

Tahapan scale–up dari suatu proses kimia, kinetika atau mekanisme dari proses tersebut perlu untuk dipelajari. Hal ini dilakukan untuk meminimalkan kesalahan dalam tahap perancangan suatu alat proses. Studi kali ini bertujuan untuk mengevaluasi model matematika yang dapat menggambarkan fenomena riil dari proses ekstraksi katalis bekas Ni/γ–Al2O3 dengan menggunakan pelarut asam sulfat (H2SO4). Studi ini melibatkan dua tahapan utama, yaitu tahap pengambilan data eksperimen dan tahap simulasi model matematika terhadap data eksperimen. Data untuk studi kinetika diperoleh melalui eksperimen proses ekstraksi dalam kondisi atmosferis di mana temperatur operasi divariasikan pada 30, 60, dan 85oC. Larutan asam sulfat yang digunakan memiliki konsentrasi 1 M, sedangkan ukuran partikel katalis kurang 74 mikron. Proses ekstraksi dilakukan selama 120 menit dengan pengambilan sampel secara berkala. Kandungan nikel pada sampel tersebut dianalisis dengan menggunakan instrumen Atomic Absorption Spectroscopy (AAS). Hasil eksperimen menunjukkan bahwa pada temperatur 85oC dan waktu ekstraksi 120 menit, nikel yang diperoleh paling banyak dibandingkan kondisi operasi lainnya, yaitu sebesar 16,95%. Studi kinetika terhadap data eksperimen tersebut menunjukkan bahwa model lump merupakan model kinetika terbaik untuk menggambarkan fenomena fisis yang terjadi selama proses ekstraksi ini berlangsung. Model lump memberikan persentase kesalahan rata–rata yang lebih kecil dibandingkan model shrinking core. Hal ini mengindikasikan bahwa tahapan difusi internal dan reaksi kimia merupakan tahapan yang mengendalikan proses ekstraksi ini.

The study examined determinants of parental school choice internationally aiming to identify research gaps and providing suggestions for researchers. Articles published between 2000 and 2023 were searched from 9 databases and a total of 30 articles were included in the review. The result showed that parental school choice is critically affected by parent-related factors like parents’ education, income, family size, and education level of the children, and the school-related factors: quality of education, performance of teachers, school facilities, school cost, parent-teacher relationship, and school curriculums are the major ones. The safety/security related and children’s educational achievement is found slightly affecting factor on parental school choice. The research design of reviewed articles is found descriptive research although the explanatory research design was appropriate as it supports better. The study also identified factors for developing and developed countries are different. For developing countries socio-economy, income, family education, cost, curriculum, technology, proximity to home, number of children, and age of the child are the major ones. For developed countries: school quality, teacher performance, special programs, playground, training teachers, library service, student moral development, school performance, environment, school ranking, interaction with parents, discipline, curriculum structure, knowledge, result, and communication skills are paid attention for parental school choice decisions.
A Retrospective Observational Study in Neonates with Transposition of Great Arteries Undergoing Balloon Atrial Septostomy in a Tertiary Care Hospital
Authors: Badge Mohanish , Choudhury Minati , B Pallavi 
Published: January 2024

Objectives:
Transposition of great arteries (TGA) is a common cause of cyanotic newborns. There is an atrioventricular concordance with ventriculoarterial discordance. This parallel circulation is incompatible with life unless communication exists for the inter-circulatory mixing of blood. Balloon atrial septostomy (BAS) is a percutaneously performed interventional procedure in catheterization laboratory, usually in patients with TGA-intact ventricular septum (IVS) to ensure admixture of oxygenated and deoxygenated blood thus improving systemic oxygen delivery, to achieve hemodynamic stability before the definitive procedure (Arterial switch operation), and to determine the risk of intraprocedural complications in neonates undergoing balloon atrial septostomy.

Material and Methods:
This is a retrospective observational study, which included neonatal patients during a single year. All the data were collected from the medical record section of the hospital.

Results:
We included 17 neonates with TGA transferred to our center for definite treatment. Six cases were done under sedation and 11 under general anesthesia. The mean age at the time of BAS was 4.8 days. Procedure-related complications occurred in 41% of patients. In one of the cases, difficult airway management made the periprocedural course daunting. Complications included intraprocedural balloon rupture (1 case), transient atrial arrhythmia (4 cases), hypotension (1 case), and pericardial tamponade due to left atrial wall puncture (1 case).

Conclusion:
BAS is a safe and effective palliative procedure for TGA-IVS, with good immediate results in our institution. Maintaining cardiorespiratory stability, prevention of respiratory depression in a spontaneously breathing neonate, and maintenance of normothermia in the cold temperature of the catheterization laboratory, with eternal vigilance, forms the cornerstone of a successful neonatal outcome.
