Numerical Study of Mixed Convection Heat Transfer in Methanol based Micropolar Nanofluid about a Horizontal Circular Cylinder
No full textIn this article, the mixed convection boundary layer flow about a horizontal circular cylinder with a micropolar
nanofluid, which is maintained at a constant surface heat flux, has been investigated. Three types of nanoparticles with
distinct conductivities, namely, graphene oxide, copper and copper oxide are considered and suspended in methanol
based micropolar nanofluid. The governing equations are transformed into nonlinear PDEs by applying the similarity
transformations and then solved numerically by an implicit finite difference scheme known as Keller-box method. The
results for the local wall temperature, local skin friction coefficient, temperature, velocity and angular velocity are
plotted and discussed for different parameters such as nanoparticles volume fraction and mixed convection parameter
in view of thermo-physical properties of nanoparticles and base fluid. Moreover, numerical results for the local wall
temperature and local skin friction coefficient are obtained. It is found that copper (Cu) suspended methanol based
micropolar nanofluid have higher velocity than the copper oxide (CuO) or graphene oxide (GO) methanol based
micropolar nanofluid. Comparison have been made with published results on Newtonian fluid under special cases and
obtained in close agreement
The Fall Of Dominant Party And The Rise Of The New Alliance Party: Pre And Post 14th General Election In Malaysia
No full textThis paper is to examine how the biggest political party in Malaysia had risen and fall. The biggest
dominant coalition party, The National Front, ‘Barisan Nasional’, was established during 1973, as a
coalition party, consists of UMNO, MCA and MIC, as a race-based component parties. It established
after the independence day of Malaysia. The rising of The National Front were ruling coalition of Malaya
from 1957 to 1963, and Malaysia from 1963 to 1973. It was then became ‘Barisan Nasional’, The
National Front from ‘Parti Perikatan’, The Alliance Party. The Alliance Party had won the most seats in
the General Election on 1959, after Malaya had gained independence on 31 August 1957, which won
74 of the 104 seats contested. Later on, the alliance party has failed and lost the 14th General Election,
2018. The research paper investigated on the reason that contributed to the downfall of the previous
government in the 14th General Election, and the rise of new coalition, and Malaysian view on the
current government in regard to its performance. Secondary sources are utilised in conducting the
research, such as books, journals, newspaper and other relevant materials. The findings shown that
certain corrupt allegations and policies implemented by previous government as contributed heavily to
the result of the 14th General Election, also other sensitive racial and religious issues had partially
contributed. While the current administration is still struggling to win the heart of majority of the
populace, promises were made to fulfil their manifesto despite numerous challenges confronted
Vis-screen: easy and rapid identification of visual impairment
No full textVisual impairment and blindness is a global problem and one of the main agenda of World Health Organization program
worldwide. Early detection and treatment are imperative for restoring normal vision. However, despite the ease of
treatment, refractive errors and cataract remain the most common causes of visual impairment and blindness due to
poor awareness and late detection. Early identification and presentation is important to improve eye care provision, in
the effort to reduce visual impairment and blindness. Vis-Screen mobile application is developed for easy and rapid
identification of visual impairment by any layperson. It is user-friendly and available in Google Play store for offline use
by anyone, anywhere, and anytime in the community. The result is auto-generated according to WHO classification and
can be shared to facilitate access with any vision and eye care providers available throughout the country

Physical Activity and Depression during Pregnancy: A Scooping Review
No full textBackground: Physical activity is considered a proper approach for physical and emotional health
improvement and maintenance. A rising body of proof defends the claim that physical activity
improves physical and mental health through down-regulation of the hypothalamic pituitary
adrenal and sympathetic nervous system. Physical activity plays an important role in the
improvement and maintenance of physical and mental health. Objectives: To identify the effect
of physical activity in reducing depression symptoms during pregnancy through scoping review.
Method: A scoping review of English academic journals based on Arskey and O’Malley (2005)
methodology framework was conducted by using three electronic databases for the period of
2015 to 2019. The review and research articles which tested the effect of any type of physical
activityor exercise measured during pregnancy on depression or depressive symptoms were
included. However, articles on pregnancy related diseases such as gestational diabetes mellitus,
hypertension, mental disorder and etc. were excluded. Relevant articles were extracted
independently. Result: Among 110 articles of the search results of electronic databases, Scopus
(n=39), Ebscohost (n=40), science direct (n=31), only thirty seven studies met our selection
criteria after screening, of which includes meta-analysis (n=8), systematic review (n=9), cohort
studies (n=11), and intervention (n=9) for antenatal depression. Conclusion: Physical activity
during pregnancy reduce depressive symptoms and may prevent depression. Studies focusing on
the effect of physical activity on depression during pregnancy and its impact on mother’s mental
health are necessary in Malaysia and Asian countries
A review of theories for metaphore examination in the expository writing of EFL learners
No full textThis paper reviews the relevant literature and theories adopted to examine the comprehension
of semantics interpretation of metaphors in the expository writing of EFL learners. Three
related theories are discussed; the cognitive theory of metaphor, the conceptual theory of
metaphor and scaffolding theory. These theories constitute the paradigms related to figurative
language in linguistics and are concerned with cognition, conceptualisation of meaning, and
the usage of language in a particular context. Whereas the cognitive metaphor theory
explicates the cognitive processes which prompt the EFL learners to acquire, reconstruct and
map both written and spoken English metaphorical expressions in mind, the conceptual
metaphor theory enables the EFL learners to make perceptual comparisons between the
metaphorical concepts in their native language and those in English. The third theory, the
scaffolding theory is useful to assess whether the comprehension of the semantic interpretation
of metaphorical expressions in a binary discussion, between Arabic and English, helps the EFL
learners to comprehend the metaphorical expressions in English language and use them in
their expository writing. This paper concludes that metaphors are not mere literary elements
for a particular group or a specified language speaker, but are integral elements of daily
human interaction with their environment and can be shared across languages, based on their
conceptual connotation
