A tractable solution is proposed to a classical problem in kinetic theory, namely, given any set of realizable velocity moments up order $2n$, closure for the moment $2n+1$ constructed which system found from free-transport term one-dimensional (1-D) equation globally hyperbolic and conservative form. In prior work, quadrature method (HyQMOM) was introduced close this fourth ($n \le 2$). Here, ...

The mechanical contribution of plant roots to soil strength has typically been studied at the ultimate limit state only. Since many geotechnical problems are related serviceability, such as deformation infrastructure, a new constitutive modelling framework is introduced. rooted treated composite material with separate relationships for and roots, comprehensive stress–strain relationship root co...

for vegetative propagation of nemaguard, st julien a, tetra and gf677 rootstocks via cutting, two separate experiments were carried out in a factorial based on completely randomized design. semi hardwood cuttings were taken in late august and then treated with concentrations of zero, 1500, 2000, 2500 and 3000 mg/l iba. cuttings were cultured in perlite medium and in a greenhouse with mist syste...

To understand the molecular mechanism of auxin action, mutants of Arabidopsis thaliana with altered responses to auxin have been identified and characterized. Here the isolation of two auxin-resistant mutants that define a new locus involved in auxin response, named AXR4, is reported. The axr4 mutations are recessive and map near the ch1 mutation on chromosome 1. Mutant plants are specifically ...

Recently, a lnorthern red oak tree was found on the Bent Creek Experimental Forest, Buncombe County, North Carolina, with an unusual and interesting group of aerial roots originating from the callused area surrounding an old wound. This tree, shown in the accompanying photograph, is about 100 feet high, has approximately 3 log lengths and is 33.5 inches in diameter at 4.5 feet above the ground....
