Effects of Visible Light Wavelengths on Seed Germinability in Stevia Rebaudiana Bertoni
Research Output | Dar Al-hikmah Library | IIUM Only

Stevia rebaudiana Bertoni is one of 154 members of the genus Stevia and it produces sweet steviol glycosides .It originated from Paraguay. The leaves were used as general sweetening agent. Seed germination in Stevia isgenerally very low and constituted major obstacle to large scale production of the crop. Different wavelengths from visible light we

On Exactly Solvable Phases of Models with Competing Interactions
Research Output | Dar Al-hikmah Library | IIUM Only

In this paper we consider Ising models with competing interactions defined on semi-infinite Cayley tree of second order. Phase diagram of such models contain new modulated phases, in addition to the expected paramagnetic and ferromagnetic phase. The aim of this paper is to select phases of these models with competing interactions on Cayley tree whi

Research Output | Dar Al-hikmah Library | IIUM Only

The term game in game theory means a problem, where some of the people or groups (players) share a set of rules and regulations that create the conditions and events that make up the beginning of the game. For instance, in the trade market, the buyers and sellers of some commodities interact in a random way. The reputation of sellers effects on inc

Research Output | Dar Al-hikmah Library | IIUM Only

The coronavirus disease 2019 (COVID-19), which emerged from Wuhan, China, is now a pandemic, affecting across the globe. Bangladesh also is experiencing the rapid growth of COVID-19 infection and death cases started from 8th March 2020. The purpose of providing a simple yet effective explanatory model for prediction of the future evolution of the c

Filling and Restoration of Cracked Digitized Paintings Based on Preserved Neighbourhood Pixels
Research Output | Dar Al-hikmah Library | IIUM Only

This paper investigates the applicability of a proposed digital image algorithm for filling cracks in digitized paintings. Filling is defined as a process of modifying/restoring damaged regions or lost areas in images. Old paintings affected by cracks suffer from decreased cultural heritage quality. Paintings that are digitized typically suffer dam

Statistical Study on the Interaction Factors of polypropylene-Graft-maleic Anhydride (pp-G-ma) with Graphene Nanoplatelet (Gnp) at Various Poly(Lactic Acid)/polypropylene (Pla/pp) Blends Ratio
Research Output | Dar Al-hikmah Library | IIUM Only

This paper reports the effects of polypropylene-graft-maleic anhydride (PP-gMA) and graphene nanoplatelet (GNP on tensile stress of various PLA/PP weight ratio. The PLA/PP blends prepared with the ratio 70/30, 80/20, and 90/10 with the addition of PP-g-MA (1 to 5 phr) and GNP (1 to 3 phr) by using an injection molding machine. The tensile stress (M
