Higher order uniication is equational uniication for-conversion. But it is not rst order equational uniication, as substitution has to avoid capture. Thus the methods for equational uniication (such as narrowing) built upon grafting (i.e. substitution without renaming), cannot be used for higher order uniication, which needs speciic algorithms. Our goal in this paper is to reduce higher order u...

considering the importance of grafted seedlings for the development of pecan orchards in subtropical regions of iran, and in order to achieve a scientifically practical method of producing grafted pecan seedlings, this project was carried out in safiabad agricultural research center of dezful during 2011-12. the project investigated three grafting methods including hot cable, hypocotyl and late...

indian ber (ziziphus mauritiana) has growing type as grape and is inclined to horizental and down ward growth. if it is not trained appropriately, it would grow into very bushy with thiny shoots. hence, such trees have short lives, and are liable to pests and diseases with low yield. fruit harvesting is also difficult in bushy trees. therefore, proper pruning and training of young trees is esse...

In this paper, grafting of acrylic acid monomer on Gum tragacanth was performed. Variable of experiment included concentration of initiators and monomer, time, and temperature. Grafting efficiency was measured in the term of percentage of grafting (%G) and percentage of grafting efficiency (%E). Effectiveness of grafted gum in ferrous ion removal at different condition was assessed. According t...

The way of making cross-linkable polyethylene through silane grafting has gained much attention in recentyears because of its various advantages such as easy processing, low cost and capital investment andfavorable properties in the processed materials. This work deals with silane grafting and moisture crosslinkingof linear low density polyethylene (LLDPE). The grafting reaction was performed i...

Hazelnuts are usually propagated by suckers or layering. However, other methods of propagation have been tested with variable results. Grafting is a method that has a few advantages such as fast multiplication rate, earlier fruiting and reducing sucker removal cost on specific rootstocks. Unfortunately, grafting is difficult due to slow formation of callus in hazelnuts. Here, we report the hypo...
