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

Stevia rebaudiana bertoni produces sweet glycosides with zero calorie and has strong health and dietary implications. With these properties, it has the potential to substitute sugar. However, poor seed germination in this plant constitute obstacle towards large scale propagation, thereby causing plant materials to be scarce and costly. High percent

This paper presents stability analysis and vibration control of a class of negative imaginary systems. A flexible manipulator that moves in a horizontal plane is considered and is modelled using the finite element method. The system with two poles at the origin is shown to possess negative imaginary properties. Subsequently, an integral resonant co

Metal matrix composites are attractive light weight materials with potential attributes to substitute automotive materials without sacrifing performance. This present study aims to investigate the wear characteristics of aluminium (Al) 6061 reinforced with silicon carbide particles (SiCp) of three (3) different particle sizes. The reinforcement con

Design of rectangular microstrip patch antenna (RMPA) using stepped cut at four corners for broadband/multiband application is presented in this paper. Stepped cut at four corner technique is used in order to increase the bandwidth and gain of the antenna. Design and simulation of Modified rectangular microstrip patch antenna are done by CST Microw

Orifice meter is a flow measuring device which is widely used in various industrial applications. Although the device gives accurate measurement during steady flow, measurement errors related to square root and sampling errors are unavoidable if pulsations exist. This research investigatesand improves the performance of an orifice plate flow meter
