Residual sisal fibers treated by methane cold plasma discharge for potential application in cement based material
(2015-12-23)
The use of residual sisal fiber is becoming more frequent as reinforcement element in organic or inorganic matrix due to its low cost, high abundance in some countries and constitutes a renewable material. However, a ...
Influência da redução a frio e da microestrutura e da textura iniciais na microestrutura, textura e propriedades de um aço inoxidável ferrítico estabilizado ao nióbio
(Universidade Federal de Minas GeraisUFMG, 2017-08-30)
The present work investigates the effect of the cold rolling, microstructure and the initial texture of the hot rolled band and intermediate annealing between cold rolling passes on the deformation texture, recrystallization, ...
Assessment of Ichu fibers as non-expensive thermal insulation system for the Andean regions
(Elsevier, 2015-12-01)
In the Andean regions, low temperatures (5 to −25 °C) combined with the wind effect give the sensation of extreme cold. Besides, in the rural areas, dwelling structures are very rudimentary, being based on adobe walls and ...
Action of propranolol on the atrial cardiomyocytes of rats submitted to cold stress
(Editrice Compositori Bologna, 1992-04-01)
Subcellular changes of the atrial cardiomyocytes of rats caused by cold showed a) altered mitochondria with edema and lysis of crests; b) myofibrils with marked heterogeneity of patterns and ruptures, c) myofilaments ...
Vitamin C prevents the effects of high rearing temperatures on the quality of broiler thigh meat
(Oxford Univ Press, 2015-05-01)
We investigated the effects of incubation temperatures and vitamin C injections into eggs (treatments: 37.5 degrees C, 39 degrees C, 39 degrees C+vitamin C) on resultant chick pectoralis major and sartorius muscle fiber ...
Modification of kapok fibers by cold plasma surface treatment for the production of composites of recycled polyethylene
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE MATERIAIS, 2018)
Correlação entre densidade de fibras nervosas em biópsia de pele e teste de quantificação da sensibilidade térmica em pacientes com hanseníase
(Universidade Federal de Minas GeraisUFMG, 2011-02-25)
It is known that, in lesions of leprosy, loss of tactile sensitivity, mediated by thick myelinated A-beta type nerve fibers, is preceded by the loss of thermal sensitivity, mediated by thin myelinated A-delta type and thin ...
Appraisal of fiber-metal laminate panels reinforced with metal pins deposited by CMT welding
(2017-11-15)
Adhesion between metal and composite is key to fiber-metal laminates (FML). CMT (Cold Metal Transfer) welding has been used for hybrid joints that couple metal pin anchoring with adhesive bonding, but this concept has not ...
