The purpose of this research was analyzing factors affecting non-participation of stakeholders in rangeland management projects. The research method was descriptive-correlative design in ranches of Piranshahr rangelands in western Azerbaijan province, Iran. All ranches that studied (Zioke Yurd, Ziuke Mirgah Chaku, Khargedashan Yurd and Gardeh Bon), are utilized in common use manner. Simple rand...

The energies of oligopeptide segments of lysozyme are minimized with respect to the dihedral angles of the central residue. As the length of the oligopeptide segment increases, up to a nonapeptide, the low-energy conformation becomes that observed in the x-ray structure in most cases. This finding suggests that, while short-range interactions appear to play the dominant role in determining the ...

there are some barriers for rangers to take part in range plan projects andevaluation. their participation is very useful for range managers to plan and provide solutionsfor solving problems. this study aims at comparing barriers of participating from rangers andexperts point of view in lar moor rangelands, tehran, iran. in this research, data werecollected based on documentation-library and fi...

Terrestrial free-space quantum key distribution is ideally suited for deployment in dense urban environments. The transition from laboratory to commercial deployment, however, raises a number of important engineering and issues. Here, we investigate these issues efficient BB84 using weak coherent pulse-decoy state protocol. We calculate expected lengths different environmental conditions when t...

Studies on experts' understanding of the public have mainly focused on the views of scientists. We add to the literature on constructions of the public by analyzing the views of decision-makers, professional science communicators and scientists involved in 'space' communication on the public and public participation in policy. Findings show that contextual situations and roles determine the way...

the selection of a growing medium is one of the most important decisions in the culture of hydroponic crops. in order to select a suitable medium for hydroponic cucumber (cucumis sativus l. cv. negin), an experiment was carried out on growing media containing different particle sizes of perlite and organic substrates in a run-to-waste system in a greenhouse experiment. the growing media tested ...
