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...

Chamomile (Matricaria chamomilla), an important medicinal plant belonging to the Asteraceae family, has a wide distribution in Iran and other parts of the world. The medicinal and pharmacological effects of chamomile are mainly associated with its essential oil content and it is widely used in food, cosmetics and pharmaceutical industries. Despite its wide geographical distribution in Iran, lit...

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...
