Authors: Gen Palma Allan , Padilla Mora Eric Ricardo 
Published: December 2023

En este artículo se exponen los resultados de una investigación de tipo cualitativa y descriptiva que tuvo por objetivo determinar las dificultades que presenta el estudiantado, en formación para profesores de matemática, en la asignatura geometría euclídea I, al resolver demostraciones y problemas que requieran para su solución del razonamiento y la argumentación. Para el estudio se seleccionó cinco ítems de la primera prueba ordinaria del I cuatrimestre del 2019; los investigadores clasificaron los ejercicios seleccionados y realizaron una propuesta según su nivel de dificultad la cual se sometió a revisión y valoración por expertos, además, el análisis se realizó a partir de dos tablas que permitieran resumir la información: una para los ítems relacionados con demostraciones y la otra para los de razonamiento, inventiva y argumentación.
En cuanto a las demostraciones se logró determinar que si logran reconocer las hipótesis, definiciones, postulados y teoremas que le podrían permitir resolverlas, pero no logran establecer las inferencias lógicas entre ellas para lograr justificar de forma correcta lo solicitado. Respecto a los ejercicios que requieren razonamiento y argumentación, se logró evidenciar que los estudiantes presentan mayores dificultades, y que por lo general emplean elementos auxiliares que poco contribuyen con la solución. Se recomienda el diseño y elaboración de recursos que ayuden con la solución de las situaciones encontradas, específicamente, se recomienda la implementación de talleres pedagógicos con los estudiantes.

Authors: Bangalore Sathyananda Rajeshwari , De Rijk Angelique , Manjunath Usha , Krumeich Anja , Van Schayck, Onno 
Published: December 2023

Background: Primary healthcare in India comprises health promotion and preventive health interventions at the population level, which are rendered at dedicated centres called Primary Healthcare Centres (PHCs). The performance of PHCs is vital for overall improvement in the general health of the population, specifically in a low- and middle-income country like India. It is unknown how performance at the centre level is related to performance at the provider and patient levels. The aim of this study is to explore patterns in the performance of three PHCs with a low, medium and the high number of babies delivered.
Methodology: Primary and secondary data from the three selected PHCs were collected. Two questionnaire studies were done: one on the well-being of providers (Quality of Life and Engagement), and another on PHC performance as assessed by patients using the newly developed tool ‘Questionnaire for Patient’s Perspective on Performance of Primary Healthcare Centres’. The data from the centre, provider and patient levels were compared across the three centres using ANOVA tests.
Results: The new tool had high internal consistency at Cronbach’s alpha score of 0.938. It was found that the PHC with the least delivery had significantly higher PHC performance in comparison with high and medium-delivery PHCs (p<0.000).
Conclusion: The PHC performance assessment from multiple perspectives offers a realistic insight into the centres, which is valid even though agreement on the various perspectives could not be obtained. The new Q4PHC is a reliable instrument to assess PHC performance from the patient’s perspective.
M/F ratios of four different closing loops: 3D analysis using the finite element method (FEM)
Authors: Safavi Mohammad Reza , Geramy Allahyar , Khezri Amir Kamyar 
Published: December 2023

Abstract

Background
It has been claimed that the opus loop is capable of delivering a constant and optimum M/F ratio without the need for gable bends.

Objective
To compare the forces, moments and moment/force (M/F) ratios of the opus loop, L–loop, T–loop and vertical helical closing loop (VHC loop) in a segmented arch with the finite element method (FEM).

Methods
The FEM was used to compare 3D models of closing loops in rectangular (0.016 x 0.022 inch) stainless steel wire. The L–, T– and VHC loops were designed with and without preactivation bends. The opus loop had no preactivation bends.
The T–Loops were 10 mm in height and 10 mm in length. The horizontal and vertical forces, the moments and the M/F ratios at the alpha and beta ends were recorded at 0, 0.1, 0.4, 0.7 and 1 mm intervals.

Results
The highest horizontal and vertical forces were produced by the L–loop (with and without preactivation bends) and in most cases the lowest forces were produced by the VHC loop. Loops with preactivation bends produced marked changes in the M/F ratio and loops without preactivation bends low, but relatively constant, M/F ratios over the full range of activation. Of the loops modelled without preactivation bends the opus and T-loop had the highest M/F ratios (7.20 – 7.67 mm at the anterior ends).

Conclusion
Stainless steel opus and T–loops without preactivation bends had constant M/F ratios, but both loops failed to deliver the optimum M/F ratio of 10:1.

Published: December 2023

Abstract

Background
Unilateral condylar hyperplasia can lead to marked and disfiguring changes in the face and occlusion. A method of determining side-to-side differences in condylar activity is an important step in managing this condition.

Aims
To determine the growth activity in normal mandibular condyles and to devise an index of side-to-side differences in condylar activity in different individuals.

Methods
Thirty eight patients, ranging from 13 to 34 years, who were undergoing skeletal scintigraphy for a variety of conditions agreed to participate in this study. No subjects had clinical or radiographic signs of mandibular hyperplasia. After injection of 25 mci Tc99 the uptake by the right and left mandibular condyles was measured and the side-to-side differences used to calculate an index.

Results
The maximum side-to-side differences were 6.2 per cent (Right side versus Left side: 53.1 per cent and 46.9 per cent respectively) in the male patients and 5.7 per cent in the female patients (Right side versus Left side: 52.85 per cent and 47.15 per cent respectively).

Conclusions
The variation in growth activity in normal right and left mandibular condyles was less than 6.2 per cent. (Aust Orthod J 2006; 22: 127–130)
The reliability of bonded lingual retainers
Authors: Cerny Robert 
Published: December 2023

AbstractBackgroundBonded lingual retainers have become increasingly popular, but there is little information on their long-term reliability.ObjectivesThe aims of this retrospective study were to investigate the reliability of bonded upper and lower lingual retainers and the factors contributing to their failure.MethodsThe study group were 149 patients who returned between 2002 and 2005 with failed upper and/or lower fixed lingual retainers. Approximately 230 patients were debonded each year and approximately 1150 patients were covered annually by a 5-year guarantee of replacement or repair of failed retainers. The retainers were made from 0.018 inch round stainless steel heat-treated orthodontic wire. The upper retainers had loops opposite the embrasures and the lower retainers had loops between the lateral incisors and canines. The following details were recorded: teeth involved, patient gender, the likely cause of any damage and the time taken for each repair.ResultsBetween 35 and 40 patients required repair/replacement of their retainers each year. Multiple bond failures occurred in approximately 9 per cent of these patients. Male patients had twice the fracture rate of female patients. Extra-oral trauma was the most frequent cause of failure followed by intra-oral trauma, operator error and wire fracture. The central incisors in both arches were the most frequent sites of failure. Single tooth repairs required approximately 12 minutes of the orthodontist’s chair-side time.ConclusionsBonded lingual retainers are a reliable form of retention after orthodontic treatment.
Effects of Sway and Roll Excitations on Sloshing Loads in a KC-1 Membrane LNG Tank

Abstract
This study investigates the effects of sway and roll excitations on sloshing liquid loads in a tank, using Ansys Fluent software. The model considered in the study is a 1:50 scaled membrane-type tank, based on a KC-1 membrane LNG tank designed by Korea Gas Corporation (KOGAS). The volume of fluid (VOF) method is used to track the free surface inside the tank, and the standard k-ε model is applied to express the turbulent flow of the liquid. To explore the motion of the tank under excitation, a user-defined function (UDF) and a dynamic mesh technique are employed to control the external forces exerted on the tank through its motion. The results, in the form of time series data on the sloshing pressures in the tank under pure sway, roll, and coupled sway-roll, are analysed, with specific ranges for the excitation amplitudes and frequencies. We show that variations in excitation frequency and amplitude significantly influence the sloshing loads. Sloshing loads are found to intensify when the excitation frequency matches the tank’s primary natural frequency, 1.0 ω1′. Furthermore, with coupled sway-roll excitations, the sloshing loads are weakened when the sway and roll are in-phase and are intensified when these are out-of-phase. Fast Fourier transform analysis provides insights into the frequency domain, showing that the dominant frequency is 0.88 Hz and it is approximately equal to the tank’s primary natural frequency, 1.0 ω1′.

Abstract
The utilisation of the thermal emissions of modern ship power plants requires the development and implementation of essentially new methods of using low-temperature waste heat. Thermoacoustic technologies are able to effectively use low-temperature and cryogenic heat resources with a potential difference of 500–111 K. Thermoacoustic heat machines (TAHMs) are characterised by high reliability, simplicity and environmental safety. The wide implementation of thermoacoustic energy-saving systems is hampered by the low specific power and the difficulties of directly producing mechanical work. An efficient approach to converting acoustic energy into mechanical work entails the utilisation of axial pulse bidirectional turbines within thermoacoustic heat engines. These thermoacoustic turbogenerators represent comprehensive systems that consist of thermoacoustic primary movers with an electric generator actuated by an axial-pulse bidirectional turbine. The development of such a thermoacoustic turbogenerator requires several fundamental issues to be solved. For this purpose, a suitable experimental setup and a 3D computational fluid dynamics (CFD) model of a thermoacoustic engine (TAE) with bidirectional turbines were created. The research program involved conducting physical experiments and the CFD modelling of processes in a TAE resonator with an installed bidirectional turbine. The boundary and initial conditions for CFD calculations were based on empirical data. The adequacy of the developed numerical model was substantiated by the results of physical experiments. The CFD results showed that the most significant energy losses in bidirectional turbines are manifested in the output grid of the turbine.
