Optimisation of shear and lateral-torsional buckling of steel plate girders using meta-heuristic algorithms
(Mdpi, 2020)The shear buckling of web plates and lateral-torsional buckling are among the major failure modes of plate girders. The importance of the lateral-torsional buckling capacity of plate girders was further evidenced when ... -
Harmony search optimisation of dispersed laminated composite plates
(Mdpi, 2020)One of the major goals in the process of designing structural components is to achieve the highest possible buckling load of the structural component while keeping the cost and weight at a minimum. This paper illustrates ... -
An improvement on selective separation by applying ultrasound to rougher and re-cleaner stages of copper flotation
(Mdpi, 2020)It has been known that the power ultrasound is used as a pretreatment and rarely applied as a simultaneous method to improve grade and recovery during froth flotation processes. This work aimed at investigating the impact ... -
Multifunctional alginate-based hydrogel with reversible crosslinking for controlled therapeutics delivery
(Elsevier, 2020)Glycan-based alginate hydrogels have great potential in creating new vehicles with responsive behavior and tunable properties for biomedicine. However, precise control and tunability in properties present major barrier for ... -

Measuring co-dependencies of economic policy uncertainty in Latin American countries using vine copulas
(Elsevier Science Inc, 2020)We analyze the dependence structure of economic policy uncertainty in four Latin American economies (Brazil, Chile, Colombia, Mexico) using vine copula modeling with various forms of tail dependence. Our results suggest ... -
Connecting measurements of solar and stellar brightness variations
(Edp Sciences S A, 2020)Context. A comparison of solar and stellar brightness variations is hampered by the difference in spectral passbands that are used in observations, and also by the possible difference in the inclination of the solar and ... -
Evaluation of NaOH pre-treatment on the corrosion behavior and surface characteristics of hydroxyapatite coated NiTi alloy
(Springer Heidelberg, 2020)Successful short-term implementation of nickel-titanium (NiTi) alloys as implants has been a motivation for the development of long-term applications. However, rendering these as safe implant materials is challenging. The ... -
Fabrication and characterization of Yb-doped Y2O3 powders and thin films
(Carl Hanser Verlag, 2020)Yttrium oxide (Y2O3) and ytterbium (Yb)-doped Y2O3 particles were synthesized via the sol-gel method from the aqueous solution of their nitrate salts. The synthesized powders were then deposited on Corning glass substrates ... -
Janus interface materials: a critical review and comparative study
(Amer Chemical Soc, 2020)In recent years, Janus interface materials with wettability contrast have attracted remarkable attention because of their beneficial properties and versatile potential applications in materials science including transport, ... -
Stream processing data decision model for higher environmental performance and resilience in sustainable logistics infrastructure
(Emerald Group Publishing Ltd, 2020)Purpose As the global freight transport network has experienced high vulnerability and threats from both natural and man-made disasters, as a result, a huge amount of data is generated in freight transport system in form ... -
Prohibition of the sale by auction of the pledged goods within the period of the concordat
(Istanbul Univ, Fac Law, 2020)To revitalize the concordat process which has lost its importance for various reasons in recent years, some amendments have been made in the provisions of the Turkish Code of Enforcement and Bankruptcy (IIK) by Law No 7101. ... -
Economic analysis of grid-connected residential rooftop PV systems in Turkey
(Pergamon-Elsevier Science Ltd, 2020)This study presents an economic analysis of grid-connected residential rooftop PVs in Turkey under the current feed-in tariff (FiT) scheme. Three solar parts are formed on the solar map of Turkey to discuss the effect of ... -
