Influence of AISI D2 Workpiece Roughness on Heat Partition and Plasma Channel Radius in the WEDM Process
(MDPI, 2020-10-12)
As an important advanced machining process, in Wire Electrical Discharge Machining (WEDM) certain fundamental issues remain need to be studied in-depth, such as the effect of part surface roughness on heat transfer mechanisms. ...
Using Y-chromosome capture enrichment to resolve haplogroup H2 shows new evidence for a two-path Neolithic expansion to Western Europe
(Nature, 2021-07-22)
Uniparentally-inherited markers on mitochondrial DNA (mtDNA) and the non-recombining regions of the Y chromosome (NRY), have been used for the past 30years to investigate the history of humans from a maternal and paternal ...
Tool-Path Problem in Direct Energy Deposition Metal-Additive Manufacturing: Sequence Strategy Generation
(IEEE, 2020)
The tool-path problem has been extensively studied in manufacturing technologies, as it has a considerable impact on production time. Additive manufacturing is one of these technologies; it takes time to fabricate parts, ...
Dimensions of social categorization: inside the role of language
(Public Library of Science, 2021-07-12)
[EN] The present pre-registration aims to investigate the role of language as a dimension of social
categorization. Our critical aim is to investigate whether language can be used as a dimension
of social categorization ...
Sorption enhanced ethanol steam reforming on a bifunctional Ni/CaO catalyst for H-2 production
(Elsevier, 2021-12)
[EN]The activity and stability of a 10 wt%NiO/CaO catalyst were tested in the sorption enhanced ethanol steam reforming (SEESR) in a fluidized bed reactor. The effect of temperature in the 600-750 degrees C range was ...
The Effect of Different Cadence on Paddling Gross Efficiency and Economy in Stand-Up Paddle Boarding
(MDPI, 2020-07-07)
Background: Due to the importance of energy efficiency and economy in endurance performance, it is important to know the influence of different paddling cadences on these variables in the stand-up paddleboarding (SUP). The ...
Thermodynamic assessment of the oxidative steam reforming of biomass fast pyrolysis volatiles
(Elsevier B.V, 2020-04-30)
[EN] The joint process of pyrolysis-steam reforming is a novel and promising strategy for hydrogen production from biomass; however, it is conditioned by the endothermicity of the reforming reaction and the fast catalyst ...
Expectations and limitations of Cyber-Physical Systems (CPS) for Advanced Manufacturing: A View from the Grinding Industry
(MDPI, 2020-09-22)
Grinding is a critical technology in the manufacturing of high added-value precision parts, accounting for approximately 20–25% of all machining costs in the industrialized world. It is a commonly used process in the ...
A comparative analysis of detachment forces and energies in initial and mature cell-material interaction
(Elsevier, 2020-06)
Single cell force spectroscopy (SCFS) enables data on interaction forces to be acquired during the very early adhesion phase. However, SCFS detachment forces and energies have not been compared so far with the forces and ...
Assessment of product yields and catalyst deactivation in fixed and fluidized bed reactors in the steam reforming of biomass pyrolysis volatiles
(Elsevier, 2020-08-02)
[EN] The performance of fixed and fluidized bed reactors in the steam reforming of biomass fast pyrolysis volatiles was compared, with especial attention paying to the differences observed in catalysts deactivation. The ...
