Authors: S. RAJKUMARI
Published: October 2023

The research was conducted with the aim of understanding the relationship between teachers’ knowledge, attitude, and practice towards learning disabilities of the students. For this study, 133 primary school teachers were chosen at random in 2022. The information on primary school teachers’ Knowledge, Attitude, and Practices (KAP) was collected by a KAP scale developed by the researcher. The scale wasvalidated and verified for reliability using Cronbach’s Alpha. The reliability score of the constructed KAP scale was 0.829, 0.854, and 0.700 correspondingly suggesting good reliability. Results showed that more than half of teachers (69.2%) had a moderate degree of knowledge and 54.9% were found to have a neutral attitude towards learning disability of the students. In terms of practices, a good level of practicesamong nealry three-fourth(72.9%) of the teachers was noted. A significant association was recorded between the knowledge and attitude of primary school teachers towards learning disabilitiesof the students. However, the results did not record practices being significantly interrelated to the knowledge and attitude towards learning disabilities of the students among primary school teachers, implying that knowledge or attitude might not influence practices as the practices remains self-regulated.

Published: October 2023

The study focused on the integration of domestic and international markets for sweet limes during 2021. The co-integration of commodity prices was considered to be necessary for the implementation of a successful marketing reform for which both domestic and international market prices are required. Due to the lack of information regarding international prices, export price information was gathered from thewebsite of the Agricultural and Processed Food Products Export Development Authority (APEDA), and secondary data regarding domestic prices of sweet lime was gathered from the website of the Agricultural Marketing Information Network (AGMARKNET). The annual average prices data for the chosen markets were gathered, and the Pearson correlation coefficient and Johansen’s co-integration analysis approaches were used to analyse the relationship between the chosen market pair. Both markets were found to be correlated through correlation analysis, and the findings of the Johansen Co-integration rank, trace test, and eigen value statistics test were used to analyse the integration among the markets. The study’s findings on market integration reveal how closely related the selected market places’ pricing are to one another. Additionally, this research demonstrated that the model’s variables exhibited an equilibrium longrun co-movement with the market price series.

Authors: Patel Priyanka , Joshi Purvee , Patadiya Tarang , Singh Sushil Kumar , Yadav Kunvar , Oza Sandip
Published: October 2023

Antarctic Ice Sheet (AIS) surface elevation change plays a crucial role in understanding the ice sheet mass balance. The present study focuses on improving AIS surface elevation estimations by incorporating slope correction methods called Direct Method (DM) using SARAL/AltiKa 40 Hz geophysical data record for 2013 (Exact Repeat Mission) and 2020 (Drifting Phase) with terrain slope ranges from 0° to 0.85°. The NASA's Ice, Cloud, and land Elevation Satellite (ICESat) Digital Elevation Model (DEM) has been utilized as a priori topography model to retrieve slope of the AIS terrain. While comparing the two direct methods (DM1 & DM2) based slope corrected elevations with Operation Ice Bridge (OIB) elevation data of November 2013, the RMSE resulted in 0.35 and 0.37 m and biases of the order of 0.26 m and 0.28 m for DM1 and DM2 respectively. Moreover, comparison with ICESat DEM showed the RMSE of the order of 1.81 and 2.09 m, and biases of the order of 0.95 and 0.99 m for DM1 and DM2, respectively. It has been observed that DM1 is the most suitable method for correcting terrain slope with the lowest RMSE and bias. Moreover, the slope induced error correction methods show utmost importance in estimating accurate elevation, especially over undulating terrain of AIS.

Authors: Chahar Anuradha , Arun S H  , Singh Charan , John Sebin
Published: October 2023

The reduction in visibility due to fog leads to cancellation of flights, delays and diversions at IGI Airport, New Delhi during the winter season. Accurate prediction of fog/ visibility is required within sufficient lead time to make the flight operations safer, economical and more convenient. This study attempts to improve the fog/visibility forecast at IGI airport for the months of December and January during the winter seasons of 2020-21 and 2021-22. Various meteorological parameters required to predict the fog/visibility are obtained from IMD GFS forecasted meteorological information which are valid for next 24 and 48-hours. Forecast verification was performed using the METAR and synoptic observations. The results for 2020-21 fog/visibility forecast for 24-hours are promising with a POD of 0.92, critical success index as 0.68, and false alarm ratio as 0.28. Moreover, the 2021-22 results for 24 -hours fog /visibility forecast are also observed to be promising with a POD of 0.73, critical success index of 0.54 and false alarm ratio at 0.32.  This method gives fairly accurate predictions in point locations and can also be used for a larger spatial area. However, the 48-hours forecast performance needs further improvement. The method also predicted the wind speed and relative humidity which were found to be in agreement with the observed data to a great extent. In the upcoming years, the fog/visibility forecast method will be more robust with better prediction accuracy of meteorological parameters from model outputs and observations.

Purpose: In an effort to lower the number of falls that occur among hospitalized patients, several facilities have begun introducing various fall prevention programs. However, the efficacy of fall prevention programs is diminished if patients do not consider themselves to be at risk for falls and do not follow recommended procedures. The goal of this study was to characterize how patients in four different acute care specialist services felt about their risk of falling while in the hospital. Methods: One hundred patients admitted to the study hospital with a Morse Fall Scale score of 45 or higher were given the Patient Perception Questionnaire, a tool designed to assess a patient's perception of their own fall risk, fear of falling, and motivation to take part in fall prevention efforts. Scores on the Morse Fall Scale were gathered through a historical assessment of medical records. Descriptive statistics, Pearson's correlation coefficients, and independent sample t tests were used to examine the data. Results: The average age was 65, and around half (52%) were men and half (48%) were women. Based on their ratings on the Morse Fall Scale, all 100 participants were classified as being at high risk for falls. However, only 55.5% of the individuals agreed with this assessment. The likelihood that a patient would seek assistance and the degree to which they feared falling both declined as their faith in their mobility improved. Patients hospitalized after a fall exhibited considerably lower confidence scores and greater fear scores than patients who had not been injured in a fall. Conclusions: Patients who have a high fall risk assessment score may not believe they are at risk for falls and may not take any steps to reduce their risk. The prevalence of falls in hospitals might be mitigated by the creation of a fall risk assessment technique that takes into account both objective and subjective factors.

Nâng cao hiệu quả của bê tông cốt lưới dệt (TRC) đối với dầm bê tông cốt thép được gia cường: Nghiên cứu về sự phát triển vết nứt và liên kết vật liệu
Authors: Trần Nam Hưng , Nguyễn Thị Thu Nga , Võ Thanh Hùng
Published: October 2023

Textile Reinforced Concrete (TRC) is a type of fine-grained concrete that is reinforced with carbon fibers, glass fibers, and other materials in the form of lattice nets. TRC can significantly increase the load-bearing capacity of reinforced concrete beams, especially under dynamic loading conditions. In addition, TRC possibly limits cracks on the beams and the environmental penetrations effects. This study aims to improve the reinforcement efficiency of TRC on reinforced concrete beams for two cases: new structures and retrofitted structures. It has been considered the changes in the strength of the reinforcement layer and the bond between the two layers of materials, namely the reinforced concrete of the beam and the TRC. The results obtained have shown that to strengthen effectively reinforced concrete beams by using TRC, two following factors need to be simultaneously ensured: enhancing the connection between TRC and the concrete in the reinforced concrete beam and TRC must have high strength. Then, TRC helps distribute stress evenly in the reinforced concrete beam, reduces stress in the steel reinforcement, strengthens stress in TRC, and reduces the likelihood of cracks in concrete, thereby improving the load-bearing capacity of the beam.

Published: October 2023

Ultra-performance concrete (UHPC) is a new material with many outstanding features such as compressive and tensile strength that are both very high compared to conventional concrete. In precast reinforced concrete structures, the beam-column joint is one of the most important parts. In this type of connection, the beam is connected to the column through post-tensioned prestressing steel bars (PC bars), making the connection resistant to bending moments as well as shear forces. This paper presents the behavior of this type of connection under the effect of seismic loads on the following criteria: flexural resistance, moment-rotational relationship, change of PC bars’ prestress during and after cyclic loading.
Phân tích tương tác nền-công trình của nhà máy điện hạt nhân
Authors: Trần Phương
Published: October 2023

Nuclear power plants are special facilities with large foundation designs, located in areas with good geology. However, in areas where seismic loads need to be considered, analyzing the soilstructure interaction of nuclear power plants is essential. Nonlinear analyses of soil-structure interaction can be performed in the time domain or frequency domain. Time domain analysis has the advantage of easily incorporating nonlinear material models or geometric nonlinearity. However, this method is limited by the boundary conditions of the geological region near the structure, as current analysis methods assume vertically propagating seismic waves towards the structure. This assumption is made to limit the errors that finite element methods can introduce at the boundaries.
This paper presents a new computational method that combines finite element method and boundary element method, in which the propagation of seismic waves towards the structure can be considered at a predetermined angle. The paper analyzes the impact of wave propagation on the response spectrum of the Kashiwazaki-Kariwa Nuclear Power Plant Unit 7. The results of the analysis show that the new computational method can consider the influence of the angle of incoming wave on the soil-structure interaction analysis.
Shear span behavior of reinforced concrete beams with circular and rectangular openings
Authors: Nguyen Trung Hieu , Pham Xuan Dat
Published: October 2023

In reinforced concrete (RC) beams, opening is frequently required for the passage of utility ducts and/or pipes. The presence of such web openings leads to a reduction of the strength and sitffeness of the beam. This paper aims to contribute to better understanding the shear behavior of RC beam with web opening in the shear span. The study is based on an experimental program carried out on three RC beams. All beam specimens were 850 mm long with a cross section of 150 × 250 mm and a shear span to beam depth ratio (a/d) of 1.48. One beam without any openings served as the control specimen, while the remaining two beams featured circular or rectangular openings within the shear span. The test results obtained from this experimental program offer insights into the shear behavior of beams with openings. Furthermore, a simplified calculation was conducted to determine the shear strength of the test specimens, considering the influence of openings. This calculation provided a deeper understanding of how openings contribute to the reduction in the shear strength of RC beams.

Authors: Tran Xuan Vinh , Nguyen Trung Hieu , Pham Xuan Dat
Published: October 2023

This paper presents an experimental study on the flexural behavior of bonded prestressed concrete (PC) beams strenthening using CFRP sheet. Two (PC) beams were fabricated, with overall dimensions of 150 × 200 × 2700 mm. One specimen served as an unstrengthened control, while the other was strengthened using CFRP sheets to enhance flexural performance. The specimens were simply supported and subjected to a four-point bending test until failure, allowing assessment of their flexural behavior. The results show that the CFRP-strengthened PC beams exhibited a 24% increase in load-bearing capacity compared to the control specimen. The stiffness of the strengthened beams was also significantly enhanced, leading to a reduction in deflection. Based on the obtained results, it is evident that the application of CFRP sheets for strengthening PC beams is a viable solution.

Authors: Sequera Jorge , Gil Javier
Published: October 2023

El monográfico que hemos coordinado y que aquí presentamos espera ser una pequeña pero necesaria contribución al estudio y comprensión de la plataformización urbana. Nuestro objetivo ha sido observar cómo el capitalismo de plataforma está transformando las ciudades, las formas del trabajo y los estilos de vidas urbanos de forma desigual y asimétrica. Donde la posición de clase (el capital económico, cultural, o social), junto a factores como el origen étnico o el género, influyen en la forma en que se participa y los efectos que tiene para los distintos grupos sociales. Para algunos, significa ampliar sus posibilidades de consumo y/o aumentar los beneficios que obtienen de sus activos. Para otros, representa una mayor precariedad, donde la inseguridad se extiende del trabajo a todos los ámbitos de la vida urbana cotidiana. En definitiva, cómo el capitalismo de plataforma está produciendo entornos urbanos que refuerzan las posiciones de clase y aumentan la desigualdad.

Published: October 2023

Changes in global precipitation would affect Indonesia to improve its water resource management system. As most watersheds are in a critical stage nowadays, it is urgent to develop a new plan and policy on water conservation that integrates the most important parameters reasonably. It has the purpose of ensuring that water resources are available for all activities and purposes within the area, especially for future periods. Integrated Water Resources Conservation Management is one of the promising approaches that is being mainly developed, particularly through the participation of all stakeholders. This participation brings equal responsibility to protect and sustainably manage the water resources, which might differ from one area to another in Indonesia. This study shows that it is important to bring up local wisdom practices on water conservation management. These could help overcome the problems related to water management in different locations in Indonesia and encourage all the stakeholders to take responsibility. All the inputs from the stakeholders are very helpful to identify the strategy at the national level, and thus it would minimize the misinterpretation between local and national levels in terms of regulation or policy. Furthermore, the approach strategies provided in this paper could improve the water national policy in Indonesia and minimize the negative potential impacts due to the lack of precipitation in the upcoming years.
Influence of Powder Oxygen Level and Particle Size on the Properties of Copper Binder Jetting Parts
Authors: Özateş Cem , Genç Bülent , Ertuğrul Onur
Published: October 2023

Copper has a huge application area thanks to its high conductivity; however, it is difficult to print additively manufactured parts with powder bed fusion methods due to its high reflectivity and thermal conductivity. Binder jetting method has a high potential for use to eliminate these drawbacks. In this study, the effects of particle size distribution and oxygen level of the copper powders on physical, and mechanical properties were investigated. It is seen that 1070°C temperature and 100% H2 atmosphere are highly required. According to Archimedes tests, lower oxygen content (LO) 10-63 powder resulted in higher density compared to LO 15-45 powder. However, image analysis show that 15–45 μm powder yields better densification, and smaller internal porosities. In higher oxygen (HO) 15-45 samples, there is inhomogeneity of pore distribution along the cross section. Consequently, LO 15–45 µm powder yields better tensile properties than HO powder.

Published: October 2023

Increasing the operating pressure and temperature of power plants is one method to increase their efficiency and hence lower CO2 emissions. The materials employed define the maximum operating parameters of a plant, ergo, it is crucial to develop new materials to raise its working conditions. Currently, alumina-forming austenitic steels), alloys vulnerable to stress corrosion cracking and irradiation swelling, are one of the materials used for temperatures about 750°C. A novel type of material is proposed, alumina-forming ferritic-martensitic steels, which have superior corrosion and swelling resistance. Advanced fabrication techniques like field-assisted sintering and selective laser melting are explored to achieve different microstructures, starting from pre-alloyed atomized powders. These microstructures were studied with SEM and EBSD, while their mechanical behaviour was observed at room temperature. Finally, corrosion tests were conducted at temperatures of 800°C for 500 hours.

Published: October 2023

Plasma Metal Deposition is a manufacturing technology which allows the fabrication of large structures. Especially for space relevant components with sizes larger than 0.5 meter, it offers a potential to fabricate parts made from light-weight metals with enhanced stiffness. The PMD process uses a plasma welding torch where powder or wire is used as a feedstock. The layer-by-layer processing allows to realize near-net-shape structures. Especially by using powder as a feedstock, there is a large flexibility in creating various alloys as well as metal matrix composites with modified properties. The aim of this study was to improve the specific modulus (ratio of Young´s modulus/density) by introducing ceramic particles into a titanium matrix. Besides addressing the main challenges in the manufacturing of composites by blown powder methods, an overview on various particles is provided. Based on microstructural analysis and mechanical testing, the influence of the different ceramic fillers is discussed.

Published: October 2023

Os silêncios de Clio, acerca das homossexualidades no Brasil, não deixa de ser surpreendente se lembrarmos que, desde a segunda metade do século XX, a historiografia brasileira, seja aquela praticada a partir de uma perspectiva marxista, seja aquela afinada com o pensamento da escola dos Annales, introduziu uma série de novos sujeitos, novas abordagens e novas problemáticas. Todavia, tal silêncio, que parece ecoar o “pensamento heterossexual”  na produção histórica, está timidamente sendo rompido. Neste artigo, analisamos as condições político-epistemológicas que têm contribuído para despertar Clio de seu longo sono heteronormativo e os desafios propostos à escrita historiográfica a partir da emergência dos estudos queer.  Palavras-chave: Historiografia; Homossexualidades; Teoria Queer.

سَعت الدراسة -عبر منهج تحليلي واستقرائي- إلى تقديم مقترح من شأنه أنْ يُسهم في إضافة أداة جديدة -في حدود ما اطلع عليه الباحث من أَدَبيِّات- من أجل التخفيف من الآثار السلبية الناجمة عن التضخم وغيره من الاضطرابات المالية والكوارث الطبيعية التي كثر وقوعها في العقود القريبة الماضية. بُني المقترح على أساس الاستفادة مما توفره مؤسَّسة الوقف من خلال ما تتسم به من مرونة في التأصيل، وسهولة ويسر في التطبيق والممارسة، وعلى أساس الاستفادة مما تتيحه التطورات التقنية الرقمية من فرص وإمكانات واعدة لإشراك قطاع واسع من فئات المجتمع للإسهام في مجالات خير متعددة؛ كل حسب استطاعته وإمكاناته. وقد تم التركيز على صيغة وقف الإرصاد بالنسبة لإسهام القطاع الحكومي في المقترح، وإنشاء منصة تمويل جماعية لتفعيل دور الجمهور (الحشود) فيما يتعلق بالاستفادة من التقنية، وهذا ما يسمح بتكوين شراكة فاعلة بين القطاع العام، والقطاع الأهلي من أجل التخطيط بشكل فاعل لما قد تُواجهُه المجتمعات المسلمة من آثار سلبية ناجمة عن التضخم وغيره من الاضطرابات المالية أو الكوارث والأوبئة الطبيعية، مع تحديد دقيق لمجال سَدِّ الخلَّة حتى لا يتداخل عمل المقترح مع غيره كصناديق الوقف في المجال الصحي. من أجل إنجاح المقترح وتفعيله توصي الدراسة بإنشاء صندوق خيري ذي شخصية اعتبارية يتولى الإشراف على المبادرة، وبنشر الوعي بأهمية المبادرة على نطاق واسع بالنسبة للقطاع الأهلي، مع استحداث التنظيمات والتشريعات المناسبة وتطبيق أدوات الحوكمة لحماية موارد الصندوق حتى تخدم الغرض المحدد لذلك. الكلمات المفتاحية: الوقف، التضخم، الإرصاد، الاضطرابات المالية، منصات التمويل الجماعي، التمويل بالحشود.

Antibiotik adalah obat yang digunakan untuk mengobati infeksi bakteri. Antibiotik dapat bersifat bakterisida (membunuh bakteri) atau bakteriostatik (menghambat pertumbuhan bakteri). Masalah terbesar dengan penggunaan antibiotik yang tidak tepat adalah resistensi. Salah satu faktor penyebab resistensi obat adalah kurangnya pengetahuan masyarakat tentang penggunaan obat terutama antibiotik. Salah satu upaya yang telah dilakukan dalam mengedukasi masyarakat dengan tema rasionalisasi penggunaan antibiotik. Sasaran pengabdian ini adalah masyarakat sekitar Losari. Perancangan pengabdian masyarakat ini menggunakan metode observational deskriptif dengan pendekatan menggunakan Google form berupa kuesioner untuk diisi oleh responden. Jumlah sampel dalam pengabdian masyarakat ini adalah 33 responden yang ditentukan secara acak di masyarakat setempat. Berdasarkan hasil analisis data kuesioner, masyarakat belum memahami penggunaan antibiotik dan resistensi antibiotik. Sehingga dilakukan tindak lanjut berupa edukasi penggunaan antibiotik secara rasional. Dengan harapan dapat meningkatkan pengetahuan masyarakat tentang penggunaan antibiotik yang rasional, maka secara tidak langsung akan menurunkan kejadian resistensi antibiotik.
