The effect of time on mechanical properties of biocompatible photopolymer resins used for fabrication of clear dental aligners
(Elsevier, Amsterdam, 2021)
Clear dental aligners are used for treating orthodontic anomalies (misaligned teeth, inappropriate contact between upper and lower teeth etc.), minor irregularities and bruxism. Using additive manufacturing technologies ...
Variable Coefficients Model for Drying Processes with Conductive Heat Supply
(Taylor & Francis Inc, Philadelphia, 2009)
The proposed model is for heat and mass transfer inside a layer of moist material placed on hot isothermal surface. The relevant thermophysical properties of the material are considered as fully dependent on local temperature ...
Application of two independent measurement techniques for determination of ductile crack growth initiation
(Springer Netherlands, 1999)
Charpy impact testing of the high strength low-alloyed steel has been performed by simultaneously recording two independent signals. The magnetic emission (ME) and potential drop (PD) techniques were used to determine ...
Crystallographic orientations of Ni3Al-based aluminide
(Elsevier Science Inc, New York, 2000)
Inverse pole figures have been plotted to determine preferred crystallographic orientations in a powder-compacted Ni3Al aluminide prealloyed with Fe, Ti and B. The main textural components, although weak, were noticeably ...
Determination of moist air drying ability using chemical potential of water vapour
(Taylor & Francis Inc, Philadelphia, 1998)
A thermodynamically simple method for calculation of chemical potential of water vapour, contained in the unsaturated moist air used as a drying medium in convective dryers, is developed. The introduced concept enables ...
Failure analysis of the end eye connection of the bucket wheel excavator portal tie-rod support
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
This paper describes the failure analysis results of the bucket wheel excavator (BWE) portal tie-rod support. The results of finite elements analysis (FEA) point out the occurrence of pronounced stress concentration, whereby ...
Austempering study of unalloyed and alloyed ductile irons
(MANEY PUBLISHING, LEEDS, 2010)
Austempered ductile iron (ADI) proved to be an advanced material as it possesses remarkable combination of high strength, ductility and toughness with good wear resistance and machinability. These properties can be achieved ...
Exploring innovative solutions for aged concrete utilization: treatment of liquid radioactive waste
(Springer, New York, 2018)
In this study, the applicability of waste concrete as a sorbent material for the liquid radioactive waste management was considered. The sample was properly characterized in terms of mineralogical and surface composition, ...
Effect of Al2O3 nanoparticles and strontium addition on structural, mechanical and tribological properties of Zn25Al3Si alloy
(Springer Heidelberg, Heidelberg, 2018)
Nanocomposites were synthesized via compocasting using Zn25Al3Si and Zn25Al3Si0.03Sr alloys as the matrices and nanoparticles of Al2O3 (1 wt%) as the reinforcement. Structure of the nanocomposites was examined, and their ...
Experimental Investigation of the Efficiency of Heat Pump Drying System with Full Air Recirculation
(Wiley, Hoboken, 2017)
The paper presents results of an experimental investigation of convective drying of apples var. Idared, potatoes var. Desiree and bananas var. Grand Nein, in full recirculation laboratory-scale dryer. The experiments were ...
