| 1761 | 2024 Article | Mining secondary metabolites of chassalia curviflora leaves using SIRIUS and high-resolution mass spectrometry data Aina Syuhada Ammar Chassalia curviflora Thwaites is a flowering plant from Rubiaceae family. Previous phytochemical investigations on Chassalia species led to the isolation of benzoic acid, benzoquinone derivatives, flavonoids, monoterpenoid, indole alkaloids and its essential oil composition. However, these are still scarce in terms of scientific reports on the studied species. This study was carried out to investigate the fast screening of secondary metabolites by using data-dependent acquisition (DDA) LC-MS/MS analysis of methanolic extract of the leaves of C. curviflora in positive ionization mode. The data were analysed using the computational mass spectrometry method from the molecular structure database search implemented in Sirius. This led to the discovering of 13 known secondary metabolites from distinct tandem MS data. De novo molecular formula annotation and predictions from SIRIUS suggested five major class compounds classified as coumarins, benzofuran, fatty acids, esters, and triterpenes. ..... 269 hits |
| 1762 | 2024 Thesis | Obstacles of applying e-training in the training and professional development centers in the Sultanate of Oman from the point of view of the trainers Al Makhashni, Sulaiman Khalaf Saeed The study aimed to identify the obstacles to the application of e-training in

| 1763 | 2024 Article | Estimating upsurge of HIV cases in Malaysia by using heun's predictor-corrector method Emmanuel, Sabastine The prevalence of HIV/AIDS remains a significant global health concern, including in Malaysia. In this study, a mathematical model was developed to simulate the dynamics of HIV transmission and progression within the Malaysian population. The model incorporates various factors such as population size, infection rate, progression to AIDS, recruitment, natural death, and death due to the disease. Heun's predictor-corrector method was applied to numerically solve the model equations and predict the population of susceptible individuals, infected individuals, and AIDS cases over time. Real-world data on HIV/AIDS cases in Malaysia were used to validate the model and provide accurate predictions. The results indicated a gradual decline in the number of susceptible individuals and an increase in the number of infected individuals and AIDS cases over the simulation period. These findings can contribute to a better understanding of the dynamics of HIV/AIDS transmission in Malaysia and aid in th..... 336 hits |
| 1764 | 2024 Thesis | An investigation of heritage architectural identity formation in globalization through painting Gharezeddin, Amjad Hani This research project investigated the formation of the architectural heritage identity in
Damascus within the context of globalization by analyzing the architectural principles of
Damascus's prevailing architecture in the contemporary era. The research aims to identify
the impact of globalization on the formation of heritage identity in terms of design and
characteristics, influence on social lifestyle and architectural aesthetics on space and
environment. The key elements in the research project consist of design and features, social
lifestyle, space and environment. The main artists involved in this research are Nazem Al-
Jaafari, Mamdouh Qashlan, Abdelkader Al Rayes, Fahd Khalif, Mohamed Salmi, Fadel
Abbas Al-Daami, Mohamed Sabry, John Sloan and Pham Xuan Trung. Work references of

architecture, the social lifestyle within the heritage and the relationship of the architecture of..... 865 hits |
| 1765 | 2023 Thesis | Exploring challenges and coping mechanisms of mental health among firefighters Nuramalina Samar This study aimed to explore the challenges of Malaysian firefighters, the impact of the
challenges, and to understand the coping strategies. The study adopted a qualitative
research method through semi-structured interviews with 23 firefighters in the central
region of Malaysia, consisting of 8 supervisors and 15 subordinates. Findings suggest
that two superordinate themes emerged relating to challenges, workplace challenges
and personal challenges, which are aligned with the affective experience as explained
through AET. The challenges impact the firefighters psychologically, which is aligned
with the affective reaction as explained by the AET but further divided into mental and
physiological, emotional as well as behavioural and psychosocial impacts. The findings
also suggest the coping strategies were derived based on emotion-focused coping,
problem-focused coping, and serving both emotion-focused and problem-focused,
reflected through social support. By uncovering the th..... 329 hits |

| 1769 | 2010 Thesis | Using process writing approach to write narrative essays Kam, Su San Most students need to improve their writing skills. Writing can be challenging. Process writing
approach can help students to develop the ability to explore new ideas through writing. During
process writing activities, students are given ample time to write, think and analyse their
narrative writing and they will be able to express ideas in new ways. The process writing does not
merely provide language exercise for the writers but gives them a chance to be adventurous with the
language as well.
The outcome of this study proved that there was improvement in the students' writing scores after
the implementation of the process writing approach. The outcome of the study also showed that there
was improvement in the organization of the narrative essays and linguistics used in the narrative
essays after the process writing activities.
Students included the characteristics of the narrative essays in their essay writing after the
second process writing activity. Th..... 523 hits |
