Language Reconciliation: Is It Theoretical, Applied or L2 (ESL/EFL) Curriculum & Instruction?

The current study aimed to demonstrate the importance of including the specialization of Curricula and Instruction of teaching English language under the general umbrella of the major of Applied Linguistics at the Faculties of Education in Egypt at the Governmental Universities. This will have several benefits, whether academic, economic or affective. The study included 50 Faculty Members specializing in Curricula and Instruction of teaching the English language selected from different Egyptian Governmental Universities at the Faculties of Education, in addition to 10 Faculty Members specializing in Applied Linguistics in the English language nominated from the Governmental Faculties of Arts at the Egyptian Universities. The study employed two instruments: TEFL Applied Linguistics Questionnaire (TALQ) and TEFL Applied Linguistics Semi-Structured Interviews (TALSSI). The data was analyzed via descriptive statistics. The study findings demonstrated the consensus of the study participants on the academic, economic and affective significance of including the major of Curricula and Instruction of TEFL under the general umbrella of the specialization of Applied Linguistics in Egyptian Higher Education Governmental Institutions. Thus, it became very highly recommended and indispensable not to separate the two majors of Curricula and Instruction of TEFL and Applied Linguistics within the Egyptian Governmental Faculties of Education

Using Online LWIBTA to Enhance EFL Intermediate Learners’ Listening and Writing Skills

The current study used a novel integrated approach based on integrating listening and writing skills which is different from the other integrated approaches, to enhance the English language listening and writing skills of the intermediate EFL Saudi undergraduate learners. The study included 100 participants, divided into 50 males and 50 females. The study employed a mixed quantitative and qualitative approach. The study instruments were the pre/post listening writing test (PPLWT), writing scoring rubric, students' weekly reflective journals (SWRJ) and the online listening and writing skills integrated-based teaching approach program (LWSIBTAP). The results of the study proved that the implementation of the 13-week study program through the Blackboard virtual sessions of one of the Saudi universities had achieved the desired results in terms of enhancing the participants' writing and listening skills. Furthermore, the collected data confirmed that the participants had strong motivation and enthusiasm to study the paragraph and the essay writing skills according to the current study program (LWSIBTAP) rather than the traditional way by just focusing on writing skills. Finally, based on the study findings, it is recommended that listening skills should be merged with writing ones when teaching writing skills to intermediate and advanced EFL learners

Combustion Characteristics for Turbulent Prevaporized Premixed Flame Using Commercial Light Diesel and Kerosene Fuels

Experimental study has been carried out for investigating fuel type, fuel blends, equivalence ratio, Reynolds number, inlet mixture temperature, and holes diameter of perforated plate affecting combustion process for turbulent prevaporized premixed air flames for different operating conditions. CO2, CO, H2, N2, C3H8, C2H6, C2H4, flame temperature, and gas flow velocity are measured along flame axis for different operating conditions. Gas chromatographic (GC) and CO/CO2 infrared gas analyzer are used for measuring different species. Temperature is measured using thermocouple technique. Gas flow velocity is measured using pitot tube technique. The effect of kerosene percentage on concentration, flame temperature, and gas flow velocity is not linearly dependent. Correlations for adiabatic flame temperature for diesel and kerosene-air flames are obtained as function of mixture strength, fuel type, and inlet mixture temperature. Effect of equivalence ratio on combustion process for light diesel-air flame is greater than for kerosene-air flame. Flame temperature increases with increased Reynolds number for different operating conditions. Effect of Reynolds number on combustion process for light diesel flame is greater than for kerosene flame and also for rich flame is greater than for lean flame. The present work contributes to design and development of lean prevaporized premixed (LPP) gas turbine combustors

Exploring novel applications of stochastic differential equations: Unraveling dynamics in plasma physics with the Tanh-Coth method

This study addresses the solution of differential equations converted into stochastic differential equations with the introduction of a noise term. To simplify the stochastic complexity, we employ a transformation, converting the equations into ordinary differential equations. The well-established Tanh-Coth method is then applied for analytical solutions to the resulting ordinary differential equations. Graphical representations of the solutions are presented, providing insights into the system's dynamics. The proposed methodology offers a robust approach to tackle the challenges posed by stochasticity in differential equations. The Tanh-Coth method efficacy in handling nonlinearities is leveraged, contributing to the analytical solution. The graphical analysis enhances the interpretation of results, shedding light on the impact of stochastic components on the system's behavior. Overall, this study provides a valuable tool for researchers and practitioners dealing with stochastic processes, offering a concise yet comprehensive approach to understanding and solving differential equations in the presence of randomness. The study aims to address the complexity of stochasticity in differential equations by introducing a noise term and transforming them into ordinary differential equations for easier analysis. Leveraging the Tanh-Coth method, it provides analytical solutions to the transformed equations, offering insights into system dynamics through graphical representations. Ultimately, the study aims to offer a robust approach to tackle stochastic processes in differential equations, benefiting researchers and practitioners dealing with stochastic phenomena

A Study on the Fiber YAG Laser Welding of 304L Stainless Steel

This work aims to optimize the main YAG fiber laser parameters to weld 304L stainless steel plates of 3 mm thick. Different laser powers (2500, 2000, and 1500 W) and speeds (60, 40, and 20 mm/s) were used and merged in heat input, maintaining the defocusing distance at –2 mm to get full penetration. The weld quality and the effect of the laser heat input on the microstructures of the weld and heat-affected zones were investigated. Besides, the fracture strength of the welded joints and hardness distribution through the cross-sections were evaluated. The weld width has a direct relationship with heat input. The laser power of 2800 W produced full penetration joints without any macro defects while reduction in laser power pronounced partial penetration defects. The size of the heat-affected zone in all the processing parameters was very small. The microstructure of the weld zone shows columnar dendrite austenite grains with small arm spacing in most of the welded zone. The size of the dendrites became finer at lower heat input. At a higher heat input, a reasonable amount of lathy equiaxed grains with some delta ferrite occurred. A small amount of delta ferrite was detected in the heat-affected zone, which prevented the crack formation. The hardness of the weld metal was much higher than that of the base metal in all processing parameters and it has a reverse relationship with the heat input. The fracture strength of the welded joints was very close to that of the base metal in the defect-free samples and it increased with decreasing the heat input
