Good quality oil with high unsaturated fatty acids was found in the seed of a medicinal plant Phaleria macrocarpa (Mahkota dewa). Different parts especially fruit flesh of this plant are being traditionally used as important folk medicine whereas seed of this plant is usually neglected. In this study, the oil was extracted from P. macrocarpa seed u

In this work, we analyze Coutte flow problem for an unsteady mangnetohydrodynamic (MHD) third-grade fluid in the presence of a pressure gradient and Hall currnts. Existing literature on the topic shows that the effecs of Hall current on Coutte flow of an unsteady MHD third-grade fluid with a prssure gradient has not yet beeninvestigated. The arisin

Abstract—The pursuit of knowledge and the use of reason, based on sense and observation is a key ingredient for research. Mathematics is a creation of human mind concerned chiefly with ideas, processes and reasoning. In this paper, we will try to give a new comprehensive definition of mathematics to understand “what is mathematics”. We will d

The pursuit of knowledge and the use of reason, based on sense and observation is a key ingredient for research. Mathematics is a creation of human mind concerned chiefly with ideas, processes and reasoning. In this paper, we will try to give a new comprehensive definition of mathematics to understand “what is mathematics”. We will discuss the

An all-fiber dual-wavelength fiber laser operating at room temperature in 1950 nm region is reported. It uses a commercial Thulium-doped fiber (TDF) and homemade double-clad Thulium-Ytterbium co-doped fiber (TYDF) as gain media in conjunction with a multimode interferometer (MMI) filter in a ring configuration. The MMI filter consists of a 13.5 cm

We report a room-temperature all-fibre dual-wavelength thulium-doped fibre laser that operates around 1900 nm and uses a spatial mode-beating filter in a ring configuration. By pumping the gain medium with an 800 nm laser and controlling the phase mismatch at the splicing points of a thulium-doped fibre, the two output lines are obtained at 1844.8

Because of interesting and useful geometric as well as topological properties, alternating knots (links) were regarded to have an important role in knot theory and 3-manifold theory. Many knots with crossing number less than 10 are alternating. It was the properties of alternating knots that enable the earlier knot tabulators to construct tables wi

This paper is devoted to establish a probability measure on a unital commutative separable Fréchet Q lmc* - algebra. Consequently a new technique to define an inner product on a unital commutative semi simple separable Fréchet Q lmc* -algebra. We have shown that the resulting inner product space is a topological algebra. At the end we have establ

Introduction: Nigella sativa seeds “black cumin” have been widely used in traditional medicine for diseases treatment including hypertension. Thymoquinone (TQ) is one of the major active constituents in its volatile oil. Objectives: The objective of the current study was to confirm the blood pressure lowering effect of TQ, and to investigate it

The build, operate and transfer (BOT) contract is a new means of project and construction financing, which includes public-private partnership. Many countries are considering the BOT contract as a mode of financing for construction projects as all citizens need public infrastructure services. This article is an attempt to describe various modes, st
