In continuation of our study of Sumatran plants and the bioactivity of their constituents, Stereocaulon halei Lamb (Stereocaulaceae) was extracted and isolated to obtain atranorin (1), lobaric acid (6), and methyl-β-orcinol carboxylate (9). We also prepared methanolic extracts of some Sumatran medicinal plants, i.e. Alpinia denticulata, Alpinia ma

Successful implementation of supply-chain management in a developing country such as Malaysia is considered a major challenge due to lack of awareness and unclear missions and goals. Focusing on this idea, this article compares the ranking of various demographic groups in relation to the internal and external barriers experienced by Malaysian manuf

Albers- Schonberg disease is an extremely rare genetically inherited disorder. Also known as Autosomal dominant Type II osteopetrosis, it is usually diagnosed incidentally. Due to the rarity of the disease, the condition is often missed and under- diagnosed. This is a case report of an eight- year old Malay girl that was diagnosed retrospectively a

This study aimed at examining the association of Corporate Social Responsibility (CSR) disclosure with access to finance by estimating the level of financial constraints faced by listed firms of the Pakistan Stock Exchange. CSR disclosure (CSRD) is attracting the attention of researchers and stakeholders and also becoming a vital source of competit

Be it academic, industrial or administrative, a continued research process is a tool of salubrious development. The chapter sheds some light on making a good and viable research proposal.

The recent technological advances trigger the emergence of the Industry Revolution 4.0 (IR 4.0) which is very dynamic and progressive to the extent most of the major industries in the world have no option left but to transform the industry accordingly in order to adapt to the changes in the IR 4.0 era. Hence, this paper aims at exploring how the le

Imbalanced class data is a common issue faced in classification tasks. Deep Belief Networks (DBN) is a promising deep learning algorithm when learning from complex feature input. However, when handling imbalanced class data, DBN encounters low performance as other machine learning algorithms. In this paper, the genetic algorithm (GA) and bootstrap

Doppler ultrasound is used in obstetrics and gynecology fields to serve as the complement mode in the standard prenatal scan. It aids in investigating fetus blood flow in expectant mothers’ wombs, usually those who come with pregnancy complications. In the conventional ultrasound beam, the heat produced by attenuation is distributed over the area

Higher education institutions in Malaysia have been facing an overwhelming demand to provide adequate facilities and resources to assist with students’ learning. The resources mentioned include ICT facilities, offices, libraries, as well as positive learning environments. Thus, this study aimed to investigate the level of students’ satisfaction

This paper is a pilot study of the effect of external forcing and passive control on the generation of airfoil whistle noise. Interaction between instability travelling inside laminar boundary layer with the airfoil trailing edge produces discrete tonal noise. This phenomenon commonly found at low-to-moderate Reynolds numbers. The characteristics a
