A duplex korrózióálló acélok a kiváló korrózióállóságuk mellett nagy szilárdságú alternatívát jelentenek családján belül, ami kettős szövetszerkezetüknek köszönhető. Ez szövetszerkezet azonban jelentősen befolyásolható hegesztési hőciklussal, ezért hegesztésükre megengedett legnagyobb hőbevitel általában 2,5 kJ/mm. Ebben kutatásban hőbevitelű hegesztésre (~ 3 kJ/mm) kifejlesztett, NSSC 2120 jel...

Abstract Duplex stainless steels offer a high strength alternative to steel, while providing excellent corrosion resistance, due their dual-phase microstructure. This microstructure can be significantly influenced during welding, thus the maximum recommended heat input is usually 2.5 kJ/mm. In this research, we inspected (3 kJ/mm) weldability of NSSC 2120 lean duplex which designed and develope...

PURPOSE The purpose of this study was to assess the susceptibility of children to the future development of caries following comprehensive treatment for early childhood caries (ECC) under general anesthesia. METHODS The patients selected for this retrospective study were identified by analyzing dental records of children receiving treatment at the Franciscan Children's Hospital & Rehabilitati...

pulp and paper effluents are considered as serious environmental hazards and their treatment, because of multiplicity of impurities and complexity of their chemical structures, is one of the most difficult and inconvenient industrial processes. as the most pulp and paper mill work on kraft process, there are few studies in literature on the treatment of neural sulfite semi chemical (nssc) proce...

two uasb reactors r-i and r-ii, each of 10liters capacity, made up of acryl material wereoperated parallel and continuously for a period of 220 days, using actual effluent of the nssc pulp and papermill, at mesophilic temperature and neutral ph. the main objective was to investigate the treatabilityperformance of the reactors at varying olr and hrt in terms of toc and lignin removal. the reacto...
