to investigate the genetic diversity of 21 rapeseeds (brassica napus l.), 20 semi-random isj and ssr primers were used. primers produced a total number of 158 (81.5%) polymorphic bands (51 ssr and 107 isj bands). average numbers of polymorphic bands for isj, ssr and combined of them were 10.7, 5.1 and 7.9, respectively. pic values ranged from 0.0150 for specific primer o110d08 to 0.3420 for sem...

Let G be a simple undirected graph of order n. For an independent set S C V(G) of k vertices, we define the k neighborhood intersections S, = { u E V(G)\SIIN(u) n Sl = 11, 1 5 ir k, with s; = ISJ. Using the concept of insertible vertices and the concept of neighborhood intersections, we prove the following theorem. Theorem. Let G be a graph of order n and connectivity K 2 2. Then G is hamiltoni...

H E amount of selection pressure applied on the phenotypic level to T metric characters can be expressed in terms of the selection differential, defined as the extent of superiority of the individuals which are the parents of the next generation (weighted for the relative number of offspring they produce) over the average of their own generation. For characters showing a discontinuous distribut...

Mutagenesis is an important tool in crop improvement. However, the hexaploid genome of wheat (Triticum aestivum L.) presents problems in identifying desirable genetic changes based on phenotypic screening due to gene redundancy. TILLING (Targeting Induced Local Lesions IN Genomes), a powerful reverse genetic strategy that allows the detection of induced point mutations in individuals of the mut...

Nano-scale nipple array on the body surface has been described from various invertebrates including endoparasitic and mesoparasitic copepods, but the functions of the nipple array is not well understood. Using the hydrophilized nanopillar sheets made of polystyrene as a mimetic material of the nipple arrays on the parasites’ body surface, we assayed the cell spreading and phagocytosis of the he...

The concept of value co-creation and the service encounter as locus of this value co-creation gained much academic interest, notably in marketing research and service sciences. While the current research discourse mainly follows conceptual perspectives, there has been little research on the practical implications on service agents’ enabling co-creation of value in the information technology (IT...
