Effect of power ultrasonic on the viscosity of anhydride epoxy resin system
Results in Materials, 2020 The effect of power ultrasonic (US) on the viscosity of an anhydride epoxy resin system has been investigated. Especially, the potential reduction of the viscosity could be used prospectively for the production process pultrusion in the variation of ...

Casting propellant in rocket engine [PDF]
, 1976 A method is described for casting a solid propellant in the casing of a rocket engine having a continuous wall with a single opening which is formed by leaves of a material which melt at a temperature of the propellant and with curved edges concentric to

Questionnaire-based pronunciation studies: Italian, Spanish and polish students’ views on their English pronunciation [PDF]
, 2012 Rather than casting new light on teaching pronunciation, the outcome of this study is consistent with the findings of other research on foreign students’ choice of preferred pronunciation model, which is undeniably native rather than foreign ...

Advanced Biology, EarlyView.The unrolling of the peltate leaves in Syngonium podophyllum is analyzed and quantified (left‐hand side to center). These measurements serve to verify a mathematical model for leaf unrolling based on the model used in Schmidt (2007). An additional formula for obtaining a layer mismatch from a prescribed radius is derived.

Efficient Decentralized Visual Place Recognition From Full-Image Descriptors [PDF]
, 2017 In this paper, we discuss the adaptation of our decentralized place recognition method described in [1] to full image descriptors. As we had shown, the key to making a scalable decentralized visual place recognition lies in exploting deterministic key ...

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.
