This study is part of the Floristic and Forest Inventory of Santa Catarina, conceived to evaluate forest resources, species composition and structure of forest remnants, providing information to update forest conservation and land use policy in Southern Brazilian State of Santa Catarina (95 000 km2). In accordance to the Brazilian National Forest Inventory (IFN-BR), the inventory applies system...
We have numerically investigated a three-body problem consisting of the Sun, an asteroid, and an infinitesimal particle initially placed about the asteroid. We assume that the asteroid has the following properties: a circular heliocentric orbit at R -2.55 AU, an asteroid/Sun mass ratio of/~ -5 x 10-12, and a spherical shape with radius R A -100 km; these values are close to those of the minor p...
Variability in woody plant species, vegetation assemblages and anthropogenic activities derails the efforts to have common approaches for estimating biomass and carbon stocks in Africa. In order to suggest management options, it is important to understand the vegetation dynamics and the major drivers governing the observed conditions. This study uses data from 29 sentinel landscapes (4640 plots...
Isothermal magnetization curves are plotted as the magnetization times the magnetic induction, 4πM · B, versus the applied field, H. We show here that this new curve is the average kinetic energy of the superconducting state versus the applied field, for type-II superconductors with a high GinzburgLandau parameter κ. The maximum of 4πM · B occurs at a field, H∗, directly related to the upper cr...
for maintaining of zagros forests role in wild life, water and soil conservation, the suitable solutions and methods for assessing the existing conditions and planning for management of this forests should be given. to detection of suitable sampling method to study tree diameter at breath height in the northern zagros forest, blake forest, in baneeh region, kurdistan province, and west of iran ...
The paper discusses incomplete sensitivity evaluations for shape optimization problems. It also shows how reduced order models can be introduced to extend the validity domain of the approach. 1 ha l-0 07 90 08 5, v er si on 1 19 F eb 2 01 3 Author manuscript, published in "Control and Cybernetics 39, 3 (2010) 615-630"

OBJECTIVES To evaluate the efficacy of intravesical instillation of hyaluronic acid (HA) after hydrodistention for the treatment of patients with interstitial cystitis (IC) having small bladder capacity. METHODS A total of 47 patients with IC (aged 27-76 years) whose functional bladder capacity was less than 200 mL received bladder hydrodistention. Thereafter, 20 patients received intravesica...
Water deficit stress, permanent or temporary, limits the growth and the distribution of natural vegetation and the performance of cultivated plants more than any other environmental factors. Mechanism involved is still not clear. In order to investigate the effect of different irrigation intervals and anti-transpirants compoundson yield and yield components of Black Cumin (Nigella sativa</e...
The objective of this study is to evaluate the capability of satellite imagery for the estimation of basal area in Northern Zagros Forests. The data of the high resolution geometric (HRG) sensor of SPOT-5 satellite dated in July 2005 were used. Investigation of the quality of Satellite images shows that these images have no radiometric distortion. Overlaying of geocoded images with the digital ...
