Tree barks are continually used and sold for medicinal purposes in Nigerian markets. Incessant debarking of trees, particularly the young trees by bark harvesters poses danger on the growth and survival of the plants. As it cannot be ascertained if the ha... see more

AbstractBackground: A reliable prediction of foetal birth weight aids in decision regarding time and mode of delivery.Aim: This study aimed to determine the accuracy of the product of symphysio-fundal height and abdominal girth in predicting birth weight ... see more

Locating-dominating sets and identifying codes are two closely related notions in the area of separating systems. Roughly speaking, they consist in a dominating set of a graph such that every vertex is uniquely identified by its neighbourhood within the d... see more

ABSTRACT. Penelitian ini bertujuan untuk mengetahui hubungan antara ukuran tubuh linier dengan bobot badan domba Texel dan Awassi. Materi penelitian adalah 35 ekor domba yang terdiri dari 20 ekor domba Texel betina umur 1-1,5 tahun dan 15 ekor domba Awass... see more

The search for the smallest possible dd-regular graph of girth gg has a long history, and is usually known as the cage problem. This problem has a natural extension to hypergraphs, where we may ask for the smallest number of vertices in a dd-regular, rr-u... see more

For a field F\mathbb{F} and functions f,g,h,j:F?Ff,g,h,j\colon\mathbb{F}\to \mathbb{F}, we define GF(f(X)h(Y),g(X)j(Y))\Gamma_\mathbb{F}(f(X)h(Y),g(X) j(Y)) to be a bipartite graph where each partite set is a copy of F3\mathbb{F}^3, and a vertex (a,a2,a3)... see more

As a natural variant of domination in graphs, Dankelmann et al. [Domination with exponential decay, Discrete Math. 309 (2009) 5877-5883] introduced exponential domination, where vertices are considered to have some dominating power that decreases exponent... see more

The tree species diversity and population structure were studied in four stands of the tropical forests in the north-central Eastern Ghats, based on tree inventories conducted on four 1-ha plots. In the four independent plots, two 5 x 1000 m transects wer... see more

The aim of this study was to compare some estimation methods (LS, M, S, LTS and MM) for estimating the parameters of simple linear regression model in the presence of outlier and different sample size (10, 20, 30, 50 and 100). To compare methods, the effe... see more
