The role of polymeric nanofibers on the mechanical behavior of polymethyl methacrylate resin
(2020-12-01)
This study aimed to synthesize and characterize non-woven acrylonitrile butadiene styrene (ABS), polyamide-6 (P6), and polystyrene (PS) nanofibers, and evaluate their effects on the flexural strength and fracture resistance ...
A Comparative Study on Graphene Oxide and Carbon Nanotube Reinforcement of PMMA-Siloxane-Silica Anticorrosive Coatings
(2016-06-29)
Carbon nanotubes (CNTs) and graphene oxide (GO) have been used to reinforce PMMA-siloxane-silica nanocomposites considered to be promising candidates for environmentally compliant anticorrosive coatings. The organic-inorganic ...
The respiratory mechanics of the yacare caiman (Caiman yacare)
(Company Biologists Ltd, 2019-01-01)
The structure and function of crocodilian lungs are unique compared with those of other reptiles. We examined the extent to which this and the semi-aquatic lifestyle of crocodilians affect their respiratory mechanics. We ...
Initial study of an alternative technology aimed at measuring and controlling the flow rate in air conditioning ducts
(2021-01-01)
This paper states that there might have around 1000 small size business jets (until nine occupants) flying across the world equipped with flow control and regulating shut-off valves that uses hot wire anemometer devices ...
Static Balancing of Four-Bar Linkages with Torsion Springs by Exerting Negative Stiffness Using Linear Spring at the Instant Center of Rotation
(ASME, 2020-08-19)
A design approach for the quasi-static balancing of four-bar linkages with torsion springs is proposed. Such approach is useful on the design of statically balanced compliant mechanisms by setting the stiffness of the ...

Computer simulation of elastic constants of hydroxyapatite and fluorapatite
(2011)
Hydroxyapatite (HAP) and fluorapatite (FAP) are essential components of dental enamel and bone. In this paper, we report a computational study of the elastic properties of HAP and FAP using ab initio and force field ...
Performance evaluation of cement mortars modified with metakaolin or ground brick
(Brasil, 2009)
The work analyzes the performance of mortars prepared with two metakaolin samples and ground calcined-clay brick. Complete stress–strain deformation response under compression, porosity, sorptivity, pore size distribution ...
Lubrication model of a knee prosthesis, with non newtonian fluid and porous rough material
(Planta Piloto de Ingeniería Química, 2009-03)
Tibial component of knee prostheses, made of ultra high molecular weight polyethylene (UHMWPE), experiences a high degree of wear and may be expected to last twelve years on average. In this work, a steady state one-dimensional ...
