---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Target coverage and data collection are the major problem in wireless sensor network. There are two types of nodes used to data collection process and target coverage. One is leaf node another one is parent node. Parent node used to collect the sen...

Rapid leaf area development may be attractive under a number of cropping conditions to enhance the vigor of crop establishment and allow rapid canopy closure for maximizing light interception and shading of weed competitors. This study was undertaken to determine (1) if parameters describing leaf area development varied among ten peanut (Arachis hypogeae L.) genotypes grown in field and pot exp...

The leaf essential oils of six members of the Annonaceae from Monteverde, Costa Rica (Desmopsis bibracteata, Desmopsis microcarpa, Guatteria costaricensis, Guatteria diospyroides, Guatteria oliviformis, and Unonopsis costaricensis) have been obtained by hydrodistillation and analyzed by GC-MS in order to compare and contrast the volatile chemical compositions of these species. The essential oil...

in order to study the effects of nitrogen fertilizer on yield and growth of soybean (glycine max l.) an experiment as factorial in rcb design with three replications was conducted during 2006 and 2007 years at north khorasan. factors were cultivar (hobbit, l.w.k., and williams), and nitrogen fertilizer (0, 50, 100, and 150 kg n/ha from urea source). results indicated that cultivar and n fertili...

In 1918 Prüfer showed a one-to-one correspondence between n-node labeled trees and (n – 2)-tuples of node labels. The proof employed a tree code, computed by iteratively deleting the leaf with the smallest label and recording its neighbor. Since then other tree codes have been proposed, based on different node deletion sequences. These codes have different properties, interesting and useful in ...
