Ionic liquids (ILs) have been used as an alternative green solvent for lignocelluloses pretreatment. However, being a salt, ILs exhibit an inhibitory effect on cellulases activity, thus making the subsequent saccharification inefficient. The aim of the present study is to produce salt-tolerant cellulases, with the rationale that the enzyme also tol

A means of supercontinuum (SC) generation is proposed and demonstrated, using femtosecond mode-locked pulses with sub-megahertz repetition rate based on the nonlinear polarization rotation technique. Total cavity length is approximately 522 m, which includes an additional 500 m single mode fiber (SMF) and the fundamental repetition rate obtained is

This study aims to investigate the impact of Computer Based Test in enhancing students’ academic performance, its acceptance and how it can be improved upon. In addition, the study also tries to access the computer ownership and its impact to students’ performance in Computer Based Testing. The study use questionnaire-based survey to gather res

A passively mode-locked, bismuth–erbium-codoped fiber (Bi-EDF) with a pulse width of 460 fs is proposed and demonstrated. A highly doped, 180-cm Bi-EDF with an erbium concentration of 3,250 ppm/wt and an absorption rate of 133 dB/m at 1,530 nm serves as the gain medium. The cavity is 11.6 m long with an overall group velocity dispersion of ?0.063

A dual-wavelength (DW) fiber laser with a closely spaced single longitudinal mode (SLM) output is proposed and demonstrated. The proposed fiber laser utilizes a conventional fiber Bragg grating with a center wavelength of about 1546.8 nm in conjunction with an ultranarrow bandwidth tunable optical filter to generate the desired DW SLM output. Obser

The individual extraction of a Brillouin Stokes line from a 20 GHz comb generated from the compact configuration of a multiwavelength Brillouin fiber ring laser configuration has been achieved using an ultranarrow bandwidth (UNB) optical filter. The narrowest bandwidth transmission of a UNB optical filter that is 50 pm is used in order to get parti

Generation of single longitudinal mode operation based on distributed Bragg reflector (DBR) cavity configuration, using a depressed-cladding erbium-doped fiber as the gain medium collectively with fiber Bragg grating (FBG) and Faraday rotator mirror (FRM) performing as the end mirrors, is proposed and demonstrated in this work for operation in the

This paper is a doctrinal legal research that adopts descriptive and comparative tools of analysis to review the concept of right in two different systems of jurisprudence, Western and Islamic. The review reveals that methodological approach to law, and in particular to the concept of right, are quite different under the two systems. Indeed, concep

Alkohol adalah satu istilah yang sinonim dengan arak, sejenis minuman yang dilarang dalam Islam. Justeru itu, muncul tanggapan bahawa kehadiran etanol yang turut dikenali sebagai alkohol, juga tidak dibenarkan dalam makanan halal. Ini secara tidak langsung menyebabkan kehadiran atau penambahan etanol dalam makanan menjadi satu isu yang cukup berkon

Health Information Technology (HIT) has the potential to improve the quality, efficiency, outcomes, patient safety and reduce the cost of healthcare. But HIT systems are not widely available, and even if available are not properly utilized. This paper reviewed some available HIT systems in order to have an idea on their availability. Also works on
