The use of remote sensing techniques as a suitable solution to estimate the levels of species diversity is of high importance for the sustainable management of forests. In order to investigate the potential of using sensor data from Landsat 7 ETM+ to estimate species diversity in the Zagros forests, digital data related to the August 7, 2002 from forests in the Qalajeh Kermanshah Province were ...

the oriental beech constitute one third of northern forests area and stocking volume in the north ofiran. these stands obseve in pure and mixed. in order to properly management which guaranteesustained yield, it is crucial to collect basic information including stocking (volume and stem number),tree growth, diameter distribution pattern, diameter-height relationship, diameter-volume relationshi...

A Hamiltonian framework for 2+1 dimensional gravity coupled with matter (satisfying positive energy conditions) is considered in the asymptotically at context. It is shown that the total energy of the system is non-negative, vanishing if and only if space-time is (globally) Minkowskian. Furthermore, contrary to one's experience with usual eld theories, the Hamiltonian is bounded from above. Thi...

An accuracy assessment of the Moderate Resolution Imaging Spectroradiometer (MODIS) vegetation continuous field (VCF) tree cover product using two independent ground-based tree cover databases was conducted. Ground data included 1176 Forest Inventory and Analysis (FIA) plots for Arizona and 2778 Southwest Regional GAP (SWReGAP) plots for Utah and western Colorado. Overall rms. error was 24% for...

OBJECTIVES This study was conducted to determine the number of hours worked per week by full-time wage workers by using the data of the Korean Labor and Income Panel Study (KLIPS), which represents the domestic urban area household, and to determine the association between weekly working hours and the level of self-rated health. METHODS We used data from the 11th KLIPS conducted in 2008. The ...

Accumulation of dry matter in siliqua, number of siliqua per plant, length of siliqua and seeds per siliqua of rapeseed (Brassica campestris L.) plants were studied under three irrigation levels (no irrigation, one irrigation at 30 DAS and two irrigations at 30 and 60 DAS) and three row spacing (20 cm, 30 cm and 40 cm). Th e experiment was carried out at Sher-e-Bangla Agricultural University (S...

Declining hearing sensitivity is appreciated as a normal age related change. However, studies reveal that health variables other than age play significant role in hearing impairment over time. Hypertension is one such variable. The objective of this study was to assess whether the hypertension has an accelerating effect on age related reduction in hearing function in males in the age group of 4...
