Compatibility Between HPEG Type PCEs With Various Anionic Charge Densities and Portland Cements With Different C3A Contents

open access: yesJournal of Applied Polymer Science, EarlyView.
Evaluation of the compatibility between PCEs possessing varying anionic charge densities and Portland cements with different C3A contents. ABSTRACT This study focused on the compatibility of phosphate and sulfonate‐substituted polycarboxylate ether‐based water‐reducing admixtures (PCE) exhibiting different anionic charge densities with Portland cements

Istanbul Flower Auction: The Need for Speed [PDF]

open access: yesarXiv
We examine a unique auction format used in the Istanbul flower market, which could transform into either Dutch or English auction depending on bidders' bidding behaviors. By introducing a time cost that reduces the value of a perishable good as time passes, we explore how this hybrid auction format accommodates the desire for speed via an adaptive ...

Violence and the City of Istanbul

open access: yesProcedia - Social and Behavioral Sciences, 2015
AbstractThe city of Istanbul historically witnessed many cases of violence. The nature of the violence changed with times and its aggravation had seasons, while some violence was almost always present in some form or another. Being a cosmopolitan urban center, violence seems to be one of the “additives” in the city's very essence and nature.

Investigation of Voltage Rise Rate Effect on the Breakdown Voltage of Solid Insulating Materials Considering Different Electrode Configurations

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT For reliable power equipment designs, it is critical to investigate the breakdown performances of insulating materials for a variety of scenarios, including various electrode geometries and voltage characteristics. In this study, the effect of voltage rise rate on the breakdown voltages of presspaper and styrene‐butadiene rubber/natural rubber

Synthesis and Characterization of Bio‐based Polybenzoxazine Hybrids From Vanillin, Thymol, and Carvacrol

open access: yesChemistry – An Asian Journal, EarlyView.
In this study, we synthesized hybrid benzoxazines from the bio‐phenolic compounds—vanillin, thymol, and carvacrol— Jeffamine D‐230, and paraformaldehyde through a Mannich reaction. The thermal polymerizations of the hybrid benzoxazines were analyzed using differential scanning calorimetry (DSC).
