Tissue culture is an attractive alternative for plant propagation. Micropropagation is a technique to ensure a constant and uniform source of ornamental plants. Matthiola incana is an important ornamental species mainly cultivate by seed. Matthiola incana seeds were germinated on solid MS medium without plant growth regulators. Shoot proliferation and root formation are possible using kinetin (...

Let k be an algebraically closed field. The generalized or n-Kronecker quiver K(n) is the with two vertices, called a source and sink, n arrows from to sink. Given finite-dimensional module M of path algebra kK(n)=Kn, we consider its dimension vector dim¯M=(dimkM1,dimkM2). F={(x,y)|2nx≤y≤x}, let (x,y)∈F. We construct X(x, y) Kn, prove it elementary. Suppose that dim¯M=(x,y). show that:if elemen...

In the present study, a Box–Behnken design of response surface methodology (RSM) was employed to optimize processing factors (force: 100, 150, and 200 kN; speed: 3, 5, 7 mm/min; temperature: 40, 60, 80 °C) for extracting pumpkin seeds oil under uniaxial compression. The generated 15 experiments including twelve combinations three replicates at center point. responses: yield (%), expression effi...

A linear k-forest is a forest whose components are paths of length at most k. The linear k-arboricity of a graph G, denoted by lak(G), is the least number of linear k-forests needed to decompose G. In this paper, we completely determine lak(G) when G is a balanced complete bipartite graph Kn,n or a complete graph Kn, and k = 3. © 2007 Elsevier B.V. All rights reserved.
