D-mbtdd: An Approach For Reusing Test Artefacts In Evolving Systems
(IEEENew York, 2016)
Tissue repairing macrophage phenotype is induced by direct interaction with platelets
(2016)
INTRODUCTION: Tissue repair process requires of specialized cells as macrophages.
These cells must be stimulated properly to induce tissue repairing macrophage to finally
heal tissue. Platelets contain many factors that ...
Synthesis and crystal phase evaluation of hydroxylapatite using the rietveld-maximum entropy method
(2004-12-01)
Bioceramic systems based on hydroxylapatite (HAP) are an important class of bioactive materials that may promote bone regeneration. The aim of this research was to evaluate how the stoichiometry of HAP influences its ...
Comparison of pixel and region-based approaches for tree species mapping in atlantic forest using hyperspectral images acquired by uav
(2019-06-04)
The objective of this work was the comparison of two different classification approaches to detect four different tree species of a highly diverse tropical Atlantic Forest area. In order to achieve the objective, images ...
Space systems design for research on the interaction of osteoblast-like cells and biomaterials (hydroxyapatite particles and titanium) in microgravity environment
(2014-01-01)
The space environment is characterized by special conditions such as the microgravity and ionizing radiations. These conditions cause major changes in human bodies, or in biomedical samples. Particularly, the bone tissue ...
Study of a Brazilian spent catalyst as cement aggregate by thermal and mechanical analysis
(2008-04-01)
Fluidized catalytic cracking units of refineries normally use zeolite catalysts to treat heavy oil fractions. This catalyst is regenerated continuously, but due to the reduction of its activity during the process, it is ...
