Maruthi Rao NVVS Sudheer <p>Quenching media, temperature and time plays vital role to improve the mechanical properties of metal and alloys.&nbsp; Tap water blend with cow urine different compositions hot metal at different temperature interval and quenched the blend and find the hardness values Al 2585 alloy. Cow urine contains different ingredients to enhance the mechanical properties of the meal and alloy. Ingredients like sodium and silicon some other elements present homogeneously improve properties like tensile strength, yield strength and hardness. Sodium refine the micro structure and silicon interlocking the grain boundaries of the metal. The model defined the relationship existing between the two variables of % of blend and temperature of specimen and hardness value, the dependent variables.&nbsp; This was correlated with existing theories are the relationship between Hardness and two variables. A analytical model was developed for the fore casting of hardness, it was proved and certified to be a positive valuation tool for estimating the hardness on the heat treatment process.</p> 2022-10-10T00:00:00-04:00 Copyright (c) 2022 Open Journal of Science and Technology The effectiveness of the use of information and communication technologies (ICT) in the teaching of general engineering in higher education in Uzbekistan 2022-10-10T14:09:40-04:00 Ulugov Bazar Dzhumaevich <p>This paper presents a systematic review of models and methodologies that integrate information and communication technologies (ICT) and education. The starting point of the review is the research questions, then keywords, selection of the databases, definition of the inclusion and exclusion criteria, the definition of the search chains, search process and selection of papers, the analysis of the paper, and the results of the systematic review to answer the questions posed. In the systematic review, 316 papers were found in three academic databases and 75 relevant papers were selected. The work developed intends to know the different models and methodologies that integrate ICT and education. The article describes the solution of problems on the subject "Descriptive geometry and engineering graphics" using computer programs and the role of pedagogical information technologies in the process of teaching students in higher educational institutions. Peculiarities of teaching descriptive geometry and engineering graphics as part of the course of engineering graphics aimed at the mastering of AutoCAD and Compass graphic editor's are considered by the authors. The authors recommend the incorporation of mini-lectures and computer workshops into the training process.</p> 2022-10-10T00:00:00-04:00 Copyright (c) 2022 Open Journal of Science and Technology Theoretical research of the process of separating impurities from cotton flow on the vibrating inclined mesh surface 2022-10-10T14:09:40-04:00 Salokhiddinova Makhliyo Nurmukhammad Qizi Rustam Muradov <p>The theoretical and experimental analysis of movement processes of raw cotton on the inclined surface (a tray) is given in the article and different factors influencing cotton cleaning process are studied. Based on developed models, there is an opportunity to determine the efficiency of raw cotton being cleaned under different angles of the inclined plane and the change in its volume. It was observed that pattern of change in coefficient of cotton cleaning efficiency by time as a result of vibration of a tray is closely dependent on compression module &nbsp;and increase in cleaning efficiency was observed.</p> 2022-10-10T00:00:00-04:00 Copyright (c) 2022 Open Journal of Science and Technology Master block pattern development for fit evaluation based on adult female anthropometric data and body shapes using Telestia-AB patternmaking system 2022-07-21T03:03:32-04:00 Norsaadah Zakaria Rosita Mohd Tajuddin <p>Developing well-fit garments is relevant in the garment industry, especially to achieve the quality of corporate uniform wear. A garment that looks good must also fit the body. The first process for garment fitting is to develop the body pattern that acts as the form for body shape before translating it to the desired garment design. Thus, the focus of this study is to construct a good master block pattern that fit the body well. Size, shape, and proportions are considered factors that contribute to a well-fitted garment. This study involves anthropometric study, master block development, pattern assembly onto fabric, basic garment constructions, and fitting analytics. The fit analytics are a relevant part of a fit evaluation to model the best method to develop body patterns and wear analysis for each individual for better-fit garment consumption. The conclusion showed that using sophisticated Telestia-AB tools and Telestia body key dimensions expedites the process of body block pattern for fit evaluation. The wear trial process is to determine how the bodice block fits before transforming it into the design pattern for corporate wear. This research concludes that developing a proper body pattern based on the anthropometric data is crucial as the fit of the garment is achievable with the right pattern-making system and skillset.</p> 2023-03-26T00:00:00-04:00 Copyright (c) 2023 Open Journal of Science and Technology Are our children financially illiterate? The case in Kedah 2023-03-22T09:03:54-04:00 Hasniza Mohd Taib Rusmawati Ismail Logasvathi Murugiah Shri Dewi Applanaidu Muhamad Noor Habibi B. Hj. Long <p class="RiAbstractText">The main objective of this paper is to identify the level of children financial literacy in Kedah and analyze the significant factors that influenced their level of financial literacy. This study surveyed <a name="_Hlk52079454"></a>320 primary school students in Kedah, aged from 7 to 12 years old using mixed method. Results shows that children in Kedah is financially literate. Besides that, there are significant different in children financial literacy according to their parent education level, parental income, student class group and school location. Based on regression results, showed that saving behavior, spending behavior, peer role, school involvement, parent role, and technology are significantly influence children financial literacy.</p> 2023-03-28T00:00:00-04:00 Copyright (c) 2023 Open Journal of Science and Technology
