In this study, presence principles were developed for dynamic display design and evaluation of dynamic display for designing mixed reality space. This is a research to classify the indicators collected through the researches about the existing measurement and evaluation of the existence felling and information suggestion methods in mixed reality as the evaluation principles of the displays and ...

Effective management of invading alien plants in natural and semi-natural systems is imperative if we are to prevent enormous impacts. An integrated approach involving the combined use of a range of methods is usually necessary to control invasive alien plants effectively. The various methods that are available are usually classified as: mechanical methods (felling, removing of invading alien p...

An invasive shrub, Chinese privet (Ligustrum sinense Lour.), was removed from heavily infested riparian forests in the Georgia Piedmont in 2005 by mulching machine or chainsaw felling. Subsequent herbicide treatment eliminated almost all privet by 2007. Recovery of plant communities, return of Chinese privet, and canopy tree growth were measured on removal plots and heavily invaded control plot...

AbstractGlobally, about 20 million ha of land area is occupied by plantations Eucalyptus . Motor-manual tree harvest-ing techniques (using chainsaws) are still applied in eucalypt plantations, especially difficult terrains or for large- sized trees where mechanised felling may not be an effective and safe possible option to apply. There little information available on motor-manual stands. This ...

This study was conducted in order to determine motivations and to identify its relationship with socioeconomic conditions of male and female participants in public exercises in the city of Tabriz. To do this, a sample containing 200 people was selected by simple randoming from statistical population. To collect information, we used SMS-6 Malite cliford et.al questionnaire for recognition of mot...

The relationship between acoustic velocity (vd) and the dynamic modulus of elasticity (me), wood density (wd), microfibril angle, tracheid wall thickness (wt,), radial and tangential diameters, fibre coarseness (co) and specific surface area (sa), within standing red pine (Pinus resinosa Ait.) trees, was investigated. The data acquisition phase involved 3 basic steps: (1) random selection of 54...
