Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

The Slavonian Dialect: between Autochtony and Influence

open access: yesMigracijske i etničke teme, 2003
The paper examines the Slavonian dialect on all linguistic levels. Special attention is given to the genesis of this štokavian dialect, and to the problems of its subdivision.

Domination parameters of a graph with added vertex [PDF]

open access: yesOpuscula Mathematica, 2004
Let \(G=(V,E)\) be a graph. A subset \(D\subseteq V\) is a total dominating set of \(G\) if for every vertex \(y\in V\) there is a vertex \(x\in D\) with \(xy\in E\).

Accuracy and safety of tablet subdivision

open access: yesMedycyna Ogólna i Nauki o Zdrowiu, 2020
Introduction Tablet subdivision is a common practice among patients and doctors. Tablets can be divided into smaller parts to obtain the desired dose and adjust this dose to the actual needs of the patient.

An interpolatory subdivision algorithm for surfaces over arbitrary triangulations [PDF]

open access: yes, 1992
In this paper, an interpolatory subdivision algorithm for surfaces over ar-bitrary triangulations is introduced and its convergence properties over nonuni-form triangulations studied.

Characterization of Nitinol Produced by Laser Powder Bed Fusion for Mechanical Metamaterial Applications

open access: yesAdvanced Engineering Materials, EarlyView.
Stabilization of L‐PBF Ni50.7Ti49.3 under low‐cycle loading was investigated. Recoverable strain after cycling was dependent on the amount of applied load. Recovery ratio was 53.4% and 35.1% at intermediate and high load, respectively. The maximum total strain reached 10.3% at a high load of 1200 MPa.

On the Influence of Antioxidants and Recycled MgO–C Source Material on the Mechanical Properties of Carbon‐Bonded Magnesia Refractories

open access: yesAdvanced Engineering Materials, EarlyView.
The presented study focuses on the fracture behaviour of carbon‐bonded magnesia MgO–C refractories, where environmentally friendly fructose, collagen and lignin serve as temporary binding agents. The partial substitution of the source material with recycled MgO–C reduces the fracture resistance, which can be counteracted by the additional introduction ...

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

open access: yesAdvanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

On Subdivision of Cycles with Two Blocks in Chromatic Digraphs Spanned by Hamiltonian Directed Paths

open access: yesMathematics
Let C be an oriented cycle with two blocks and let n denote the number of its vertices. We show that every (n+2)-chromatic digraph spanned by a Hamiltonian directed path contains a subdivision of C. This bound is tight.
