Monolithic silica columns and their use in high peak-capacity HPLC separations are reviewed. Monolithic silica columns can potentially provide higher overall performance than particle-packed columns based on the variable external porosity and variable through-pore size/skeleton size ratios. The high permeability of monolithic silica columns resulting from the high porosity is shown to be advant...

abstract strawberry is one of the most important fruit crops in the world. in this study, effect of different plant densities were studied on yield and fruit quality of strawberry 'selva' in greenhouse and laboratories of university college of agriculture and natural resources during 2002-2003. uniform stolens of strawberry were planted in holes of plastic column according to factorial in compl...

Syntactic structures have been good features for opinion analysis, but it is not easy to use them. To find these features by supervised learning methods, correct syntactic labels are indispensible. Two possible sources to acquire syntactic structures are parsing trees and dependency trees. For the annotation processing, parsing trees are more readable for annotators, while dependency trees are ...
