Helicoidal single-layer cylindrical coil self-inductance evaluation : a didactic method
(2001) [Journal article]This paper presents a didactic mathematical method to evaluate the self-inductance of a nonmagnetic core single-layer cylindrical and helicoidal coil presenting voids between turns. This type of calculation, using Biot–Savart ... -
Heterogeneidade de temperaturas em fornos de nitretação a plasma
(2008) [Journal article]Nitretação a plasma é um processo que tem sido mais fortemente estudado nos últimos 30 anos e suas vantagens técnicas, econômicas e ambientais sobre os processos convencionalmente utilizados já estão bem estabelecidas no ... -
Heterogeneous photocatalytic degradation of dyes in water/alcohol solution used by the brazilian agate industry
(2019) [Journal article]The agate dyeing industry has been commonly seen as a high-pollution industry. Dyeing wastewater treatment is considered one of the most important categories for water-pollution control, because of its intense colour and ... -
Hide unhairing and characterization of commercial enzymes used in leather manufacture
(2011) [Journal article]The enzymatic treatment of hides in tannery processes is a promising technology. However, the reaction kinetics of commercial enzymes available to the leather industry are not fully understood and their activities have ... -
Hidratação na idade inicial de cimentos contendo ye’elemita (YCC) produzidos com catalisador gasto (SFCC)
(2024) [Journal article]Diante dos impactos ambientais associados à produção do cimento Portland convencional, o estudo de cimentos especiais de reduzido impacto ambiental tem sido uma tendência. Neste contexto, os cimentos contendo ye’elimita ... -
A hidrogeomorfologia como ferramenta para popularização e desenvolvimento de SABO no Brasil
(2021) [Journal article]A gestão integrada de redução de desastres com base em SABO vem se popularizando no Brasil, que por sua vez é tradicionalmente conhecido no Japão como o conjunto de ciência-tecnologia-cultura, o qual busca sistemas de ... -
A high-fault-coverage approach for the test of data, control, and handshake interconnects in mesh networks-on-chip
(2008) [Journal article]A novel strategy for detecting interconnect faults between distinct channels in networks-on-chip is proposed. Short faults between distinct channels in the data, control, and communication handshake wires are considered ... -
High-order finite volume method for solving viscoelastic fluid flows
(2008) [Journal article]Computational Fluid Dynamics (CFD) is widely used by polymer processing industries in order to evaluate polymeric fluid flows. A successful computational code must provide reliable predictions (modeling) in a fast and ... -
High-pressure structural phase transitions in semiconducting niobium dioxide
(1999) [Journal article]Niobium dioxide was studied up to 47 GPa by angle-dispersive, x-ray powder diffraction. Semiconducting α − NbO 2 (space group I 4 1 / a , Z = 32 ) was found to transform to β − NbO 2 (space group I 4 1 , Z = 16 ) above 5 ... -
High-temperature mechanical properties of cast Al–Si–Cu–Mg alloy by combined additions of cerium and zirconium
(2020) [Journal article]The main aim of this work is to investigate the effects of combinative Ce and Zr additions (0.3 wt% Ce+0.16 wt% Zr; 0.3 wt% Ce+0.27 wt% Zr and 0.3 wt% Ce+0.36 wt% Zr) on the microstructure and mechanical properties ... -
H-induced subcritical crack propagation and interaction phenomena in (001) Si using He-cracks templates
(2010) [Journal article]H and He ion implantations allow the formation of nanocracks within controlled subsurface depths in semiconducting materials. Upon annealing, crack propagation and coalescence provides a way of cutting monocrystalline thin ... -
Historical analyses of debris flow disaster occurrences and of their scientific investigation in Brazil
(2015) [Journal article]Considering the debris flow as highly-destructive flow of water and sediment mixture in a way where it is a gravity-governed continuous flow, the present paper conducted a Web survey of technical-scientific studies that ... -
How the use of stratigraphic coordinates improves grade estimation
(2015) [Journal article]Some mineral deposits show mineralization along layers. These layers may pass through several subsequent geological events such as folding and/or severe erosional processes. Grades within these deposits tend to be correlated ... -
Human dental pulp stem cell adhesion and detachment in polycaprolactone electrospun scaffolds under direct perfusion
(2018) [Journal article]Cell adhesion in three-dimensional scaffolds plays a key role in tissue development. However, stem cell behavior in electrospun scaffolds under perfusion is not fully understood. Thus, an investigation was made on the ... -
