SHIFTS AND HARVESTING SYSTEMS ON QUALITY OF IMPURITIES SAMPLES IN SUGARCANE
(Soc Brasil Engenharia Agricola, 2017-05-01)
Semi-mechanical and mechanical harvesting methods may influence the content of impurities in harvested sugarcane. This study aimed to evaluate the quality of three mechanical methods of sugarcane harvesting: one semi-mechanical, ...
6061 Al reinforced with silicon nitride particles processed by mechanical milling
(Pergamon-elsevier Science LtdOxfordInglaterra, 2002)
Radiative processes in jets
(World Scientific, 2010-06)
Relativistic jets and collimated outflows are ubiquitous phenomena in astrophysical settings, from young stellar objects up to Active Galactic Nuclei. The observed emission from some of these jets can cover the whole ...
Mechanical behavior of isolated intervertebral disc
The study on several components of intervertebral joints is essential to understand the spine's degenerative mechanisms and to assess the best method for their treatment. For such study it is necessary to know the mechanical ...
Pellets prepared with mechanically activated iron ore
This work analyses pellets prepared with iron ore that has been mechanically activated by high energy ball milling. Pellet feed iron ore was submitted to high-energy ball milling for 60 minutes, and the resulting material ...
Bovine Bone Screws: Metrology and Effects of Chemical Processing and Ethylene Oxide Sterilization on Bone Surface and Mechanical Properties
(SAGE PUBLICATIONS LTD, 2009)
We assess the effects of chemical processing, ethylene oxide sterilization, and threading on bone surface and mechanical properties of bovine undecalcified bone screws. In addition, we evaluate the possibility of manufacturing ...
Processing, thermal and mechanical behaviour of PEI/MWCNT/carbon fiber nanostructured laminate
In this work, nanostructured composites of polyetherimide (PEI) with addition of functionalized multiwall carbon nanotube (MWCNT) were processed via solution mixing. After processing, these nanocomposites were evaluated ...
Comparison of Mechanical and Microstructural Characteristics in Maraging 300 Steel Welded by three Different Processes: LASER, PLASMA and TIG
The maraging steel are considered ultra high strength due to its yield strength greater than 1400 MPa and are part of a set of advanced materials of interest for technological development, mainly for aeronautics and aerospace ...
Assessment of the mechanics of a tissue-engineered rat trachea in an image-processing environment
(Universidade de São Paulo (USP), Faculdade de Medicina, 2014-07-01)
OBJECTIVES: Despite the recent success regarding the transplantation of tissue-engineered airways, the mechanical properties of these grafts are not well understood. Mechanical assessment of a tissue-engineered airway graft ...
