One of the wood industry activities in forestry sector is Eucalyptus sp at PT.Riau Mainstay Pulp and Paper Riau Province. The production process used for pulpand has many factors its productivity. them planting with weedcontrol problems, which use herbicide active ingredient glyphosate. glyphosate not effective against all types weeds. Therefore, it necessary to know right combination weed cont...

THES P A C E P R O B L E M S of large collections as well as those of libraries that have almost reached their capacity are obvious. What has been belatedly recognized are the signscant secondary problems and costs that are involved. Collections containing a significant number of necessary but little-used books are an impediment to the patrons’ accessibility to titles. Such collections increase...

a series of polystyrene hybrid nanocomposites have been fabricated with varying amounts of tio2 viz., 0, 0.5 and 1 % w/w along with 3% ts by in-situ polymerization method. the influence of surface modified tio2 nanoparticles on the thermal properties of ps matrix was examined using thermogravimetry and differential scanning calorimetry. thermal characteristics of the polystyrene/ts/tio2 hybrid ...

an experiment was conducted in bandar kyashahr research field in 2002 to evaluate the effects of plant density and planting pattern on weed populations and yield of peanut (arachis hypogaea l.). the experiment was of a randomized complete block design with three replications. a factorial trial with two factors of planting pattern (square and rectangular arrangements) and plant density (3, 5.3, ...

a new mechanical cultivator was proposed for mechanical weeding in part one. the precise point method was used to geometric design of this new cultivator. the aim of this research is selecting the suitable mechanism of the studied mechanisms in part one. the velocity and acceleration of links (kinematic) is the base of dynamic analysis of the systems. the variation of velocity, acceleration and...

North American prairie vegetation has been a role model for designing highly attractive plantings for German urban green spaces for the past decade. In combination with gravel mulch top layers on planting sites and non-selective maintenance techniques like mowing or burning, prairie plantings are considered to be cost-effective and low-maintenance. This study was undertaken to assess the impact...
