2. Edaphic and Topographic Factors and their Relationship with Dendrometric Variation of Pinus Taeda L. in a High Altitude Subtropical Climate
ABSTRACT The study of the relationships between the yield potential of forest stands and the conditions offered for plant development is fundamental for the adequate management of the forest when aiming at sustainable high yields. However, these relations are not clear, especially in commercial forests, on rugged terrain where relationships between the lands

3. High-resolution topography for Digital Terrain Model (DTM) in Keller Peninsula, Maritime Antarctica
Abstract High resolution topography (HRT) surveys is an important tool to model landscapes, especially in zones subjected to strong environmental changes, such as Antarctica, where landform is highly influenced by cryoclasty and permafrost melting. The aim of this work was to obtain a high accurate DTM for Keller Peninsula, Maritime Antarctica. The survey st

4. Synergistic effect of honey and Nigella sativa on wound healing in rats
Abstract Purpose: To investigate the therapeutic potential of honey, Nigella sativa (N. sativa) and their combination in rat model of excisional wound healing. Methods: A circular excision wound was established in the back region of 50 Wistar rats. Subsequently, they were divided into 5 groups and daily topical administration of lanolin in the control gr

7. Experimental analysis and theoretical predictions of the limit strains of a hot-dip galvanized interstitial-free steel sheet
In this work, the formability of a hot-dip galvanized interstitial-free (IF) steel sheet was evaluated by means of uniaxial tensile and Forming Limit Curve (FLC) tests. The FLC was defined using the flat-bottomed Marciniak's punch technique, where the strain analysis was made using a digital image correlation software. A plastic localization model was also p

9. Comparação entre mapas de solos obtidos pelos métodos convencional e digital numa área complexa / Comparison between soil maps obtained by conventional and digital methods in complex area
Soil maps are essential for the development of agricultural areas in an economically viable and environmentally friendly manner. So far, Brazil only has soil maps of small scale (1:250,000 to 1:1,000,000), whose use is limited to agricultural and environmental planning at the farm. Despite its importance, in Brazil a few mappings have been carried out by pub

11. BUILDING 3D DETECTION AND EXTRACTION IN INFORMAL SETTLEMENT AREAS / DETECÇÃO E EXTRAÇÃO 3D DE EDIFICAÇÕES EM ÁREAS DE ASSENTAMENTOS INFORMAIS
Informal settlements in many Brazilian urban centers are growing up quickly. Remote Sensing techniques provide a cost-effective mean to measure such an expansion. In cities with rough topography, like the city of Rio de Janeiro, the initial expansion, predominantly horizontal, is gradually being shifted to vertical, as new floors are being built on the exist

12. Modeling and simulation of device variability and reliability at the electrical level
In nanometer scale complementary metal-oxide-semiconductor (CMOS) parameter variations pose a challenge for the design of high yield integrated circuits. This work presents models that were developed to represent physical variations affecting Deep- Submicron (DSM) transistors and computationally efficient methodologies for simulating these devices using Elec
