Data visualizations make data easier for the human brain to understand, and visualization also makes it easier to detect patterns, trends, and styles in groups of data. With the development of the data visualization, more and more data which contains the information of disabled population has been collected. However, researchers have pointed out some problems with visualizing data especially using traditional methods. Therefore, this study aimed to develop a web-based system for data visualization of disabled people distribution in Kuala Selangor, Selangor, Malaysia. Prototyping methodology was chosen in order to develop the web-based system. The results show two main interfaces of the web system which are the admin module and user module. Users may see a specific area, type of disabled people categories and the number of disabled people in the located area from the Google Map. This web system is hope to help public in identifying disabled people location using data visualization techn.....

The present study was designed to evaluate the anticancer properties of girinimbine and its derivatives. Two different routes for the synthesis of girinimbine involving a two-step reaction or a one-pot reaction were studied. Girinimbine was synthesised through metal-catalysed heterocoupling, indole ring closure, ether formation, and Claisen cyclisation. Girinimbine derivatives were prepared by the semi-synthesis of isolated girinimbine from Murraya koenigii through alkylation or acylation reactions. Natural and synthetic girinimbines, five derivatives of N-substituted girinimbine, and three intermediates from the synthesis of girinimbine were evaluated for cytotoxicity activity against human lung cancer (A549) and normal lung (MRC-5) cell lines. The structures of all the synthesised compounds were confirmed by spectroscopic analysis and comparison with published data. The cytotoxicity assay showed that the natural girinimbine and nitrobiphenyl intermediate exhibited high toxicity (IC50.....

Eleven undescribed triterpenoids (pentandrucines A to K) were isolated from the n-hexane extract of the stem bark of Chisocheton pentandrus (Blanco) Merr. These comprised ten undescribed dammarane-type triterpenoids and one undescribed apotirucallane-type triterpenoid. Additionally, two dammarane-type triterpenoids, four apotirucallane-type triterpenoids and two tirucallane-type triterpenoids were also isolated. The chemical structures of pentandrucine A-K, were fully elucidated using 1D and 2D-NMR, and high resolution MS. All of the compounds were evaluated for cytotoxic activity against MCF-7 breast cancer cells in vitro. Melianodiol proved to be the most active with an IC50 of 16.84 ?M comparing favourably with Cisplatin (13.2 ?M). ? 2021 The Author(s)..

Cyber aggression has become a growing problem in today's society. It offers convenient opportunities to humiliate, bully, or harass others online. Global studies on cyber aggression found that youths who were aggressed online reported feeling depressed, anxious and afraid. They showed poor academic performance, and experiencd eating disorders, alcohol, drugs and substance abuse. Therefore the study aimed to investigate the interrelationships between predictive factors namely peer attachment, parental attachment, exposure to the Internet and cyber aggression-victimization among youths. The renowned general aggression model (GAM) was applied to understand the phenomenon. A sample of 430 urban youths aged between 13 and 18 years living within Klang Valley area were randomly selected to participate in the study. Data were gathered through self-report questionnaires and later analyzed using SPSS and AMOS. The results revealed several noteworthy findings; most of respondents made use of the .....

Solar energy has long been utilised in crop conservation. The use of solar dryers as a drying method overcomes the drawbacks of the traditional approach to drying crops under the sun. Previous studies were coherently described and focused on the development and thermal convection of greenhouse dryers, structural analysis, crops cultivation for offering choices to reader about solar greenhouse dryers in agriculture. Based on the previous related studies, the current work proposes an evolve and detail review of solar-assisted greenhouse dryers, namely, passive dryers, active dryers and hybrid dryers, from the aspects of system performance, collector performance and the drying characteristics of various crops. Drying crops in a solar greenhouse dryer protects crops from insects, rain and dust. Thus, these dryers are preferred in natural and conventional drying. This review provides a satisfactory guide for researchers to compare, develop and improve solar greenhouse drying systems to achi.....

This study aims to identify cultural values present in ?Das Schenkenbuch? by Johann Wolfgang vonGoethe. This study uses qualitative analysisthrough text analysis approach. Data for this studyis focused on cultural values where it is obtainedthrough reading, recording and scoring techniques.Data validity was obtained through an appointedintrarater. The results reveal that there are fewcultural values conveyed by Goethe in this poemwhich resonates with 7 cultural elements proposedby Edmund Anderson (1996). Among the elementsthat were discovered in the poem are values onreligion and belief, confidence, value of humanpractice and the knowledge system is also found inthe Malay culture, including the development ofhuman knowledge and community practices. Thereis no doubt that this poem also contains artisticvalue that is so subtle and distinctive ? 2021, Global Journal Al-Thaqafah. All Rights Reserved...

The purpose of present study is to analyses the critical success factors of WEP implementation in Malaysia. The study indicates six critical success factor of WEP (entrepreneurial traits, entrepreneurial experience, management skill, customer relation, training and education and environment). A total of 38 responses from women entrepreneurs in Malaysia were collected through email and on-line questionnaires. The result shows the mean values are 5.811 to 5.461, consider good at WEP implementation. The dimension TE (5.811) and EE (5.758) have the highest mean value and shown to be the most important dimensions of WEP implementation for women entrepreneur in Malaysia SMEs. The implications present study is anticipated to help better understand women entrepreneurs' condition, needs and provide new insights for the critical success factors of a more gender-specific practice for women entrepreneurs in Malaysia. This study also provides important guidelines to implement WEP. In future researc.....

The versatilities of calixarenes have been known primarily in the host-guest world. In this work, two calix[4]arenes, namely C-DHC4 and N-DHC4, possess the same lower rim but are distinct in the upper rim. The Langmuir Isotherm and optical properties have been carried out using Langmuir?Blodgett trough and UV-Visible spectroscopy, respectively. The topographical image of the calix[4]arenes has been observed using FESEM, and lead cation entrapments of these calix[4]arenes have been inspected using the surface potential sensor. The isotherm graph revealed the size of each calixarene; C-DHC4 ~ 1.90 nm2 and N-DHC4 ~ 2.10 nm2 . The UV-Visible result demonstrated that each calix[4]arene has two firm absorption peaks where C-DHC4 has two broad peaks, which lie in 261 and 330 nm, while N-DHC4 has two shoulders at 275 and 282 nm. FESEM images have shown the formation of calix[4]arene nanocluster. Further monitoring on the surface potential and effective dipole moment indicate that C-DHC4 perfor.....

This corpus-driven study explores the linguistics phenomenon of mental verbs in English song lyrics from 1960s until 2000s. This study aims to identify the frequency distributions of lexical verbs, mental verbs, and to analyze the language uses of mental verbs in the Diachronic Corpus of English Song Lyrics (DCOESL). Quantitative and qualitative methods of analysis were applied. First, quantitative data covering frequency distributions of general verbs was produced via LancsBox. Top three mental verbs in song lyrics were selected for analysis and discussion. The frequency distributions of mental verbs and collocations were produced via LancsBox. Collocational patterns were illustrated through collocational graphs constructed via LancsBox. Frequency distributions of mental verbs were compared to reference corpus Contemporary Corpus of American English (COCA) for the purpose of generalizing the findings from this study as representative of English language. The statistical data were subm.....
