Recently, different methods have been proposed to develop wood materials, termed “densified woods”, with density increment and improvement in mechanical proprieties. Almost all the involve use of reducing agents strong bases. In this work, a new method has developed involving less polluting agents. The formation densified woods is divided into two steps: delignification involves removal lignin,...

The first and second Born approximation are studied with the path integral representation for T matrix. The T matrix is calculated for Woods-Saxon potential scattering. To make corresponding integrals solvable analytically, an approximate function for the Woods-Saxon potential is used. Finally it shown that the Born series is converge at high energies and orders higher than two in Born approxim...

in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
Tree fruit orchards in some Mid-Atlantic states are within the geographic range of 17-year periodical cicada Brood X, Magicicada septendecim (L.) and M. cassini (Fisher) (Hemiptera: Cicadidae), can be badly affected by injury from its oviposition branches. Several applications broad-spectrum insecticides, such as pyrethroids, needed to mitigate this injury, but incite secondary pest outbreaks i...
Schnyder woods are a well-known combinatorial structure for plane triangulations, which yields a decomposition into 3 spanning trees. We extend here definitions and algorithms for Schnyder woods to closed orientable surfaces of arbitrary genus. In particular, we describe a method to traverse a triangulation of genus g and compute a so-called g-Schnyder wood on the way. As an application, we giv...
