Novel of neodymium nanoparticles zinc tellurite glasses in experimental and theoretical elastic properties using artificial intelligence approach
Muhammad Noorazlan Abd Azis
All the parameters under experimental elastic properties showed non-linear variations for Nd2O3 nanoparticles. Rocherulle and Makishima-Mackenzie's model involving theoretical elastic was retrieved and compared, along with bond compression and ring deformation models and experimental elastic properties. The corresponding set of data indicates comparable values with Makishima-Mackenzie and Rocherulle models. Although, the experimental elastic moduli exhibit higher values from bond compression model data in comparison with similar experimental values. Therefore, this model is not suitable for this glass system. Predictions from the artificial neural network (ANN) model interpreted through the relationship between the predicted and the experimental values provide an excellent R2 coefficient, lying between 0.9916 to 1.0000 for all values. This great approach via artificial neural network model has proven its validity for future glass research. 2022..

The bitcoin halving cycle volatility dynamics and safe haven-hedge properties: a MSGARCH approach
Phoong, Seuk Yen
This paper introduces a unique perspective towards Bitcoin safe haven and hedge properties through the Bitcoin halving cycle. The Bitcoin halving cycle suggests that Bitcoin price movement follows specific sequences, and Bitcoin price movement is independent of other assets. This has significant implications for Bitcoin properties, encompassing its risk profile, volatility dynamics, safe haven properties, and hedge properties. Bitcoins institutional and industrial adoption gained traction in 2021, while recent studies suggest that gold lost its safe haven properties against the S&P500 in 2021 amid signs of funds flowing out of gold into Bitcoin. Amid multiple forces at play (COVID-19, halving cycle, institutional adoption), the potential existence of regime changes should be considered when examining volatility dynamics. Therefore, the objective of this study is twofold. The first objective is to examine gold and Bitcoin safe haven and hedge properties against three US stock indices be.....

Intelligent emotion and sensory remote prioritisation for patients with multiple chronic diseases
Alamoodi, Abdullah Hussein
An intelligent remote prioritization for patients with high-risk multiple chronic diseases is proposed in this research, based on emotion and sensory measurements and multi-criteria decision making. The methodology comprises two phases: (1) a case study is discussed through the adoption of a multi-criteria decision matrix for high-risk level patients; (2) the technique for reorganizing opinion order to interval levels (TROOIL) is modified by combining it with an extended fuzzy-weighted zero-inconsistency (FWZIC) method over fractional orthotriple fuzzy sets to address objective weighting issues associated with the original TROOIL. In the first hierarchy level, chronic heart disease is identified as the most important criterion, followed by emotion-based criteria in the second. The third hierarchy level shows that Peaks is identified as the most important sensor-based criterion and chest pain as the most important emotion criterion. Low blood pressure disease is identified as the most i.....

Systematic literature review: Interpretation of lah discourse particles in Malaysian speech [Sorotan literatur bersistematik: Interpretasi partikel wacana lah dalam ujaran masyarakat Malaysia]
Anida Sarudin
The particle "lah" in the aspect of discourse is an affirmative word that has various roles in utterance. The term discourse particle is used to describe the existence of pragmatic interpretation through use in a particular context. The various interpretations of the discourse particle "lah" resulting from existing studies not only provide input related to its structure but also cause confusion regarding its use. In line with that, the need for research to compile the findings of previous studies should be implemented to synthesize the use of these discourse particles in terms of coverage of the debate, its form and function. The methodology of this study which is a Systematic Literature Review study is based on the PRISMA standard (Preferred Reporting Items for Systematic Review and Meta Analysis). Three main databases were used namely Scopus, Dimensions and Google Scholar. This study used thematic analysis with the help of ATLAS.ti 23 software. Based on the analysis conducted, 102 in.....

Development of schoolpreneur model for Malaysian secondary school: a confirmatory factor analysis approach
Sharul Effendy Janudin
This study aims to develop a schoolpreneur model appropriate for Malaysia's secondary school environment. The current study surveyed students participating in the Program Tunas Commerce (PROTUNe) and the Young Entrepreneurs Association (PUM) in the states of Perak, Selangor, and Negeri Sembilan to accomplish these purposes. A survey-based technique was used to collect data, and 400 students participated. With a cross-sectional research design, this research uses a quantitative research methodology. This research employed exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and structural equation modeling (SEM) for statistical analysis. The study's findings show that six highlighted factors can be incorporated to develop a schoolpreneur model. These factors all significantly affect the schoolpreneur model. A significant correlation of the schoolpreneur model of more than 60% indicates the significance of talent skills, mentors, incubators, individual personality, role.....

Embracing gen-z
Embracing gen-z's learning styles with a mobile enthalpy game application (MEGA) for thermochemical equation
Gen-Z is digital natives with unique learning styles. Gen Z is attracted to mobile technology and interactive visual learning materials. Therefore, the mobile game application seems to engage Gen Z in learning abstract chemistry topics. This paper focuses on the effectiveness of an Android game app, mobile enthalpy game application (MEGA) to facilitate students to write thermochemical equations and study its effect on their achievement in the topic. The study involved 72 Malaysian science matriculation students divided into control and treatment groups. The impact of MEGA (treatment group) versus PowerPoint slides (control group) on students performance writing thermochemical equations was compared. Results showed significant differences in pre and post-test scores for students in MEGA and PowerPoint groups. Students in the treatment group surpassed the control group's performance in the post-test scores. To conclude, the mobile game apps (MEGA) seemed to be able to promote gen Zs achi.....

A review: characteristics and prevalence of psychrotolerant food spoilage bacteria in chill-stored meat, milk and fish
Suzita Ramli
As the human population increases globally, the demands for getting high-quality and nutritious food content are also getting higher. However, the emergence of food spoilage microorganisms is remained challenging to fulfil societys demands in the current food industry. Food spoilage microbes can be introduced into any point across the farm-to-fork supply chain to cause notable degradation in contaminated food, therefore making it unsuitable for human consumption. The majority of food spoilage microbes will not cause serious illness even when consumers have accidentally ingested the contaminated food. Chilling and freezing are commonly used to inhibit microbial proliferation on food quality. However, neither chilling nor freezing are ineffective for psychrotolerant and psychrophilic spoilage microbiota, respectively due to their good adaptation to survive in chilling or freezing temperatures (below 4C or lower than 0C) to cause spoilage in refrigerated food. In this article, the process.....

Isotherm behaviour of P3OT, P3HT and PCBM langmuir layer on ionic subphase
Syed Abdul Malik Syed Mohamad
Isotherms are generally curves that depict the phenomena that govern a substances mobility at a constant temperature and pH. In this study, the Langmuir layer of P3OT, P3HT and PCBM were characterised by computing their surface pressure as a function of the surface area available to the molecules at the interface to obtain a curve called surface pressure area (?-A) isotherm. All three polymers were spread on two types of subphases-DI water and water containing bivalent metal ions, Pb2+. None of the Langmuir layers exhibits discrete gas-liquid-solid phase transitions on the water subphase. However, more stable Langmuir layers formed when lead ions were added to the water subphase. The stability enables the capping of lead ions between the polymer chain or within the balls, which can be implemented in flexible electronic devices. 2023, Penerbit Akademia Baru.
