The present research was conducted to find the influence of some topographic factors on distribution of large-leaved lime (Tilia platyphyllos Scop.) and its natural regeneration characteristics in "Vaz" forest (northern Iran). After identification of site and preparation of topography map, selective sampling method was carried out for tree inventory in plots. The sample plots were circular in 1...

abstract malacoplakia is a rare chronic inflammatory disease associated with infection and immunosuppression, and very few occurrences have been reported in the bone. the authors describe the case of a 22-year-old woman with paraplegia and urinary and fecal incontinence whose thoracic spine magnetic resonance imaging suggested a tumoral or extensive inflammatory process in the body of the 8th, ...
Introduced and invasive species have been recognized as potential threats to natural plant communities. Many such plant species are introduced along roadways, which then can spread to adjacent fields and forests. The West Virginia Division of Highways is required to develop seeding mixtures comprised of native plants for revegetating highway corridors and thereby to reduce the potential for int...

In dry lands, semi-circular bund has been considered as a management practice used to restore the ecological revival in terms of vegetation enrichment and soil amelioration. This study was conducted to investigate the effects of semi-circular bunds on vegetation cover and some soil properties in Koteh rangeland, Sistan and Baloochestan province, Iran (2014). Adjacent to the semi-circular bund a...
One of the methods to increase the incomes utilization of range is recreational use from rangelands, but these uses can have negative effect. So in this study, we were investigated the effect of recreational use from rangeland on carbon sequestration in Miankale biosphere reserves. In order to, after preliminary identification, for sampling from ecotourism area and non-ecotourism area, tw...
Silvicultural operation need to notice the species diversity. To this study Gomarlang district in marivan region, northern zagros forest was selected. In this study 30 circle sample plots (500 m2) were collected by random method. In every sample plot the kind of species and number of trees and shrub were recorded. In the sample plots the micro plots of 5 m by 5 m (i.e. area of 25 m2) were desig...
A mathematical method for accurately determining the upper and lower diffuse-fraction (kd) limits that divide sky into clear, intermediate, overcast is developed. Fourteen sites around world are selected demonstrating methodology. The kd values these determined from scatter plots of direct-normal solar radiation vs. pairs over typical meteorological year each site. They vary between 0.73 0.80 0...
