In this paper we found an exact formula for a finite sub-tree counting problem. Note that the formulas, which correspond to two extremal cases, are Catalan Triangle introduced by Shapiro and ballot Catalan triangles. The general formula could be expressed as a linear combination of these Catalan triangles.Southeast Asian Bulletin of Mathematics c/â

In the present paper,we investigate stability of trajectories ofLotka–Volterra (LV) type operators defined in finite dimensional simplex.We prove that any LV type operator is a surjection of the simplex. It is introduced a newclass of LV-type operators, called MLV type ones, and we show that trajectories of the introduced operators converge. More

This study on the tangible cultural heritage of the Dutch, Baba Nyonya and Chinese was conducted at the Heeren Street and Jonker Street, focuses on whether the elements of architecture buildings, landscape, street lifestyle and economy practiced by the people are recognisable by the tourists.These also reflects the successions of the identity of th

Background: Textile and dye industries pose a serious threat to the environment. Conventional methods used for dye treatment are generally not always effective and environmentally friendly. This drove attention of scores of researchers to investigate alternative methods for biodegradation of dyes using fungal strains. In this work, whiterot fungus

In the present paper, we consider orthogonal preserving quadratic stochastic operators defined on infinite dimensional simplex. We provide a full descriptions of such kind of operators. Moreover, certain examples are given.5 / 1 2 / 2 0 1 7 J o u r n a l o f P h y s i c s : C o n f e r e n c e S e r i e s , V o l u m e 8 1 9 , 2 0 1 7 ­ I O P s c

Processing of rare earth elements produces environmental wastewater pollution containing toxic contaminants. However, these pollutants could be monitored through bioaccumulation using aquatic plant, Pistia stratiotes. Thus, the present research aims to determine the effectiveness of P. stratiotes in the bioaccumulation of rare earth metals through

The period of 1970s was the time when Malaysia started to experience environmental problems including various threats facing the wildlife as a result of rapid economic growth, deforestation and urbanization. In an effort to solve these environmental problems, Malaysia took a number of countermeasures including the enactment of the Protection of Wil

Telecommuting has been recognized and promoted as a strategy for alleviating traffic congestion in urban areas, especially reducing rush-hour traffic. Substantial evidence in the literature suggests that Telecommuting is more suited to women who when compared to men, experience more work/non-work role conflict and more career interruptions. This re

The 13th general election in 2013 (GE13) was the most recent general election in Malaysia. It was a display of stiff competition as the main opposition coalition at the time, Pakatan Rakyat (PR), was a strong competitor for Barisan Nasional (BN), the ruling coalition. BN learned its lesson from the 12th general election campaign in 2008 (GE12) and

Purpose – Since middle of 1960, the clove production has continually and significantly decreased due to some problems and challenges which include financial ones. The financial intermediaries such as banks, cooperatives and micro-enterprises provide micro-financing to the farmers with high interest rates along with collateral requirements. The nu
