There is a growing interest in the area of designing and synthesis of functional dye molecules that can serve as molecular devices for sensors,photo-switching and signal transduction. Among photochromic compounds that could be used for such purpose are spiropyrans. This paper presents an alternative analysis of 6-nitro-1’,3’,3’-1-benzopyran-2

Mosque is one of the major establishment within a Muslim community in countries with Muslim majority as well as countries where Muslims are minority. It is almost inevitable that every Muslim community would have at least one mosque within the locality. For most of the cases in Muslim major countries, there are more than one mosque to be found in a

This paper presents optimization of vibration damping for a rectangular thin plate using a single piezoelectric (PZT) patch shunted with negative capacitance, by utilizing the ant colony optimization (ACO) algorithm. The frequency range to be controlled is presented in the context of statistical energy analysis (SEA) where modal overlap factor (MOF

Orange-spotted grouper (Epinephelus coioides) is known to be one of the economically high values marine. However, its spawning condition is still not well understood by the aqua culturist in Terengganu, Malaysia. Fish farmers depend on natural supply by col-lecting eggs of orange-spotted grouper from the wild. A study was conducted to deter-mine th

This paper examines the acoustic properties of two pairs of English vowels: /i:/, /ɪ/ and /u:/,/ʊ/ produced by two sets of Malay speakers. This study was motivated by claims that Malaysian English (MalE) speakers do not distinguish these vowels’ phonemic lengths. The data was obtained from the recordings of five Malay informants. The recordings

Abstract: Complex fluid problems arise during fluid-structure interactions and pose a major challenge in the development of a stable generic numerical approach. Owing to the robustness of flowfield dependent variation (FDV) method in dealing with complex flow interactions, a new numerical procedure using the FDV method coupled with arbitrary Lagran

The present research study was aimed to isolate and detect for biosurfactant producing microorganisms from Palm Kernal Cake (PKC). Seven bacteria were isolated from PKC and labelled as SV1, SV2, SV3, SV4, SV5, SV6 and SV7. It was found that almost all the bacteria are potential biosurfactant producers as they were positive for most of the detection

Two bright solitons in a dipolar Bose–Einstein condensate (BEC) can form stable bound states, known as soliton molecules. In this paper we study the scattering of a two-soliton molecule by external potential, using the simplest and analytically tractable Gaussian potential barriers and wells, in one spatial dimension. Collisions of soliton molecu

Cu, Zn, Ni and Pb concentrations in surface sediments collected from 10 stations in the western part of the Johor Straits were determined. Samples were acid digested and metal concentrations were determined by atomic absorption spectrometry (AAS). The obtained results showed that Zn had the highest concentration (111.7±78.8 g/g) among the selected

Two anti-phase bright solitons in a dipolar Bose-Einstein condensate can form stable bound states, known as soliton molecules. In this paper we study the scattering of a twosoliton molecule by external potential, using the simplest and analytically tractable Gaussian potential barriers and wells, in one spatial dimension. Theoretical model is based
