this study was performed in order to consider the effect of management plans on forest, through comparison between qualitative and quantitative characteristics of managed and unmanaged forests. compartment no. 149 from shourab district (52.8 ha) and compartment no. 218 from jamand district (68.7 ha) were selected as managed and unmanaged forests, respectively and were inventoried using a system...
Cement bonded particleboards were manufactured from hornbeam (Carpinus betulus L.) wood particles. Hydration tests were carried out to determine the inhibitory index in order to characterise wood-cement compatibility. The results revealed that the mixture of hornbeam -cement can be classifi ed as moderate inhibition. Two wood: cement ratios were applied in this study, namely 1:3 and 1:4, for th...
Number theoretic public-key solutions, currently used in many applications worldwide, will be subject to various quantum attacks, making them less attractive for longer-term use. Certain group constructs are now showing promise providing quantum-resistant cryptographic primitives, and may provide suitable alternatives those looking address known attacks. In this pap...
To date, the lichens Chrysothrix candelaris and Varicellaria hemisphaerica have been classified as accurate primeval lowland forest indicators. Both inhabit particularly valuable remnants of oak-hornbeam forests in Europe, but tend toward a specific kind of vicariance on a local scale. The present study was undertaken to determine habitat factors responsible for this phenomenon and verify the i...
Forest type maps play a significant role in sustainable forest management. For many years aerial photos and satellite data were a primary data source supporting forest type mapping. Recent developments in remote sensing provide opportunities to further enhance forest type maps by introducing variations of spectral, biochemical and biophysical properties at various scales. A structural sampling ...
In the present study, the effect of some pre-treatments implemented on seeds of Oriental hornbeam (Carpinus orientalis), which has wide geographical variation along Turkey on germination percentage values were investigated. For this purpose, 13 different pre-treatments were implemented to seeds obtained from 17 different populations. According to the obtained results (except control seeds), pre...
Projection of stand development over time relies on accurate height-diameter functions. In this study, we evaluated the capability of 43 nonlinear models to estimate hornbeam heights in a portion Rezaeian experimental forest in Gorgan, Golestan province. We applied a systematic random sampling method to collect field data within a 150×200 meter network (3.33% intensity). It resulted in 200 circ...

Borkowski, Department of Psychology, University of Notre Dame. The first author was supported by Grant Number T32 HD07184-27 from the National Institute of Child Health and Human Development. The second author was s...
Abstract At present, ecosystems are facing changes caused by global warming and anthropogenic impacts on geochemical cycles. Both temperature nutrient availability affect litter decomposition; however, little is known about their simultaneous effect decomposition in temperate forests, especially for nutrients such as Na K. To address this perspective, we investigated how N, P, K supply increase...
