In this study, it is aimed to improving the extrusion capability of AA5083 aluminium alloy with high magnesium (Mg). The thermo mechanical response of a magnesium alloy directly affected by extrusion parameters is highly complex. First of all, the casting experiments with chemical composition based on different rate of the magnesium (Mg) and chrome (Cr) were performed in this study. In the homogenization heat treatment, the billets have a 127 cm diameter were heated at 480°C and 500°C with 480 and 600 minutes. The homogenized billets were subjected to shock cooling till reach room temperature. In the extrusion process, the investigation of the different parameters (billet and mold temperature, press speed (mm/s), press pressure (bar), press time (s) on the extrusion capability were performed..........

The study developed and implemented an interactive web-based student complaint management system that addressed the challenges faced by students in tertiary institutions. Currently, students struggle with the difficulties of registering complaints and receiving slow responses. The computerized complaint management system provides students with a safe space to express their concerns without the fear of consequences. The design of the system was based on the data flow model and was developed using PHP, JavaScript, HTML, CSS, and MySQL. The MySQL server served as the database management system and Visual Studio Code was used as the integrated development environment. The final outcome of this research is an effective and user-friendly web-based student complaint management software that meets its objectives and provides an efficient solution to the challenges faced by university students.

Machine learning is a brand-new frontier in healthcare. Yet, it is unclear if the introduction of machine learning would have a favorable or detrimental impact on the healthcare industry. This paper thoroughly examines this argument. This is accomplished by looking at data that was gathered via an online poll that included 10 questions asking medical professionals about the impact machine learning has on various aspects of healthcare. The results of the study share how automation enhances operational efficiency, communication, and reduces medical error, etc.

The reaction of isoprene with ozone have been conducted. The reaction samples were analyzed by FTIR and GC/MS at various time. After reaction,new observed absorptions in IR spectrum included -OH, C=O, and C-O vibrational modescombined with the fragment analysis of new observed peaks of GC/MS spectrum,indicated the isolated products areformaldehyde, methacrolein,methyl vinyl ketone, 3-methylfuran,3,4-epoxy-3-methyl-1-butene, 3,4-epoxy-2-methyl-1-butene, methacrylic acid, and methyl-1,2,3,4-diepoxybutane.These products were resulted in three possible reaction paths, reaction of isoprene with O3 (as Scheme I),isoprene with O atom(as Scheme III), and isoprene with OH and O2 (as Scheme IV).

Research in the past has identified several frameworks associated with Corporate Social Responsibility (CSR) and suggested that there may be a correlation between a corporation's CSR activities and consumer behavior. This paper explores the concept of CSR through an economic and psychological lens by diving deeper into the theoretical aspects of CSR and conducting case studies of global companies across various industries. Economic graphs are first drawn to explain how CSR revolves around the concept of externalities and deadweight loss. By developing a 3-step psychological framework, the paper highlights how CSR can influence customer perception of a brand in both the short and long term.........

The main objective of this research work is to demonstrate the effectiveness of a group psychoeducational workshop based on cognitive-behavioral techniques, on addictive behavior to video games in a group of adolescents from the Instituto Bolívar school. For this study, a quantitative approach methodology was developed, with a quasi-experimental pretest-posttest research design of a single group. The sample was taken as 12 young people from the Bolívar Institute in an age range of 13 to 16 years, identified with problems of addiction to video games, according to the pretest evaluation carried out through the instrument Evaluation and prevention of addiction to the Internet, Mobile and video games. (ADITEC-M)..........

Thoi Trang Canal area in Kien Binh commune, Kien Luong district, Kien Giang province, Vietnam has many peat mining enterprises operating because the quality of peat meets the requirements for organic fertilizer. This study aims to identify the impacts on the natural environment of the area due to peat mining activities. The long-term mining process may cause some negative impacts on the environment, if there are no measures to prevent, control and treat environmental pollution. The next possible impacts are effects on the area's landscape and natural resources, air pollution from mining and transportation activities, possibility of surface water pollution due to mining activities and daily life of workers on the construction site.
