All the efforts put in developing questionnaire by a researcher are in vain if it measures what is not intended to measure. A questionnaire can only be useful if it produces meaningful and trustworthy data. The aim of this study was to develop and assess the validity and reliability of an instrument to measure the perception and attitude of diabeti

This paper considers a mathematical analysis for steady two-dimensional boundary layer flow and heat transfer of a Jeffrey fluid over a stretched sheet. The thermal boundary layer equation takes into account the effect of viscous dissipation along with Ohmic dissipation due to a transverse magnetic field and electric field. The highly non-linear mo

This paper presents a steady two-dimensional boundary layer flow and heat transfer of a Jeffrey fluid over a stretched sheet with non-uniform heat source/sink. The governing equations that govern the fluid flow and heat transfer are solved using the Keller-box method after being reduced to a set of non-linear ordinary differential equations by a si

This paper describes the setup and experimental results for an entirely centred erbium-doped fiber laser with passively mode-locked output. The gain medium of the ring laser cavity configuration comprises a 3m length of two-core optical fiber, wherein an undoped outer core region of 9.38 μm diameter surrounds a 4.00 μm diameter central core regio

Recent theoretical and methodological innovations have given rise to novel approaches for conducting investigations in the multitude of disciplines and topics within the social sciences. This research seeks to explore how poststructuralist theory, as one representative of these approaches, can contribute to debates surrounding multicultural politic

This paper describes a dual wavelength single longitudinal mode (SLM) demonstration for a proposed ytterbium-doped fiber laser. A dualtapered Mach-Zehnder interferometer (MZI) was inserted into the laser ring cavity setup to ensure a stable dual wavelength and SLM operation. The consequent dual wavelength lasing operation had a wavelength spacing o

Natural chitosan derived from chitin can be obtained from crustacean shells as well as squid pen which usually considered as waste materials. Natural chitosan is biodegradable, biocompatible, non-toxic, anti-microbial, and possesses adsorption properties. Squid chitosan which is derived from β-chitin can be used as thickening agent in cosmetics fo

Household debt in Malaysia has been on an upward trend and increasing at a relatively fast pace. This study provides an in-depth micro analysis of the current Malaysian urban households’ vulnerabilities by examining the extent of their ability in dealing with financial shocks and factors that attribute to their financial fragility. Using a recent

The purpose is to provide an overview on the incidence of gallstone disease in patients with various types of inherited (chronic) hemolytic diseases at risk of cholelithiasis/choledocholithiasis with particular emphasis on its pathogenesis, genetic, risk factors and management. A detailed electronic literature search to determine the source of mate

Purpose: To identify the structural requirements for designing a lead key for insulin-like growth factor (IGF-1R) inhibition using group-based quantitative structure activity relationship (GQSAR) and molecular docking. Methods: GQSAR method requires fragmentation of molecules. The molecules in the current dataset were fragmented into three (R1, R2
