This study investigated the effect of cultivation parameters on microbial oil production from hydrolysate of oil palm empty fruit bunch (EFB) using fungus Mucor plumbeus. The parameters selected for evaluation were sugar concentration (30–100 g/L), yeast extract concentration (0–13.3%, g yeast extract/g sugar), pH (5–7) and spore concentratio

A passively Q-switched S-band fiber laser using Molybdenum Diselenide (MoSe2) saturable absorber (SA) is proposed and demonstrated. The SA is fabricated by depositing MoSe2 onto two fiber ferrules using the drop-cast method before heating and connecting the two fiber ferrules to form the SA. The passively Q-switched fiber laser designed using the M

A thulium-doped fiber laser (TDFL) with a tunable Q-switched output is proposed and demonstrated. A silver nanoparticle based saturable absorber is used to generate the Q-switched pulses, while a tunable Mach-Zehnder filter acts as the wavelength-tuning mechanism. The TDFL has an operating wavelength range of 1916.5-1945.3 nm, with output pulses th

This report makes a comparison between the spectrum features of plasmonic metamaterial metal-insulator-conductor (MIC) sensor with a monolayer of graphene and another MIC sensor with a multilayer of graphite as the back reflector. In both structures, the silicon substrate as an insulator layer was sandwiched between subwavelength periodic nanogold

Poverty is considered one of the basic problems confronted by the developing and underdeveloped countries of the world including Muslim majority countries like Pakistan. During the last two decades, microfinance institutions have been rapidly established all around the world on the premise that they can alleviate poverty. These institutions open ne

Oil palm empty fruit bunch (EFB) is a lignocellulosic biomass and has the potential to be converted into oil that can be used as the feedstock for biodiesel production. The production of microbial oil from EFB can be performed through biochemical routes of cultivating oleaginous microorganism on EFB hydrolysates. Oleaginous microorganisms, includin

This study investigates the steady-mixed convection boundary layer flow near a stagnation point that runs about a linearly stretched vertical surface filled with a Jeffery fluid in the presence of a transverse magnetic field. It is assumed that the external velocity impinges normally to the wall and the wall temperature varies linearly with the dis

The problem of steady Casson nanofluid flow past a wedge is studied in this paper. The presence of magnetic field along with Newtonian heating at the surface is considered. The governing partial differential equations are first transformed into a set of nonlinear ordinary differential equations by similarity transformations, before being solved num

This paper looks into some of the claims made by Mirza Ghulam Ahmad Qadiyani against the Prophet Isa (as). Mirza’s claims were not only discourteous to Isa (as), but were also not in line with the fundamental beliefs propagated by Islam. The Qur’an and Sunnah has emphasized Isa’s Prophet-hood, his reverence, his miracles, his ascending and hi

A classification, up to isomorphism, of two-dimensional (not necessarily commutative) Jordan algebras over any algebraically closed field is presented in terms of their matrices of structure constants.Classification of two-dimensional Jordan algebras Houida Ahmed , Ural Bekbaev , and Isamiddin Rakhimov Citation: AIP Conference Proceedings 1905 , 03
