Basic Leaching Behavior of Mechanically Activated Zinc Plant Residue
(Springer, 2019)
Zinc plant residue is a secondary metal source because it has precious metals such as zinc and lead. However, since this residue contains partial ferrite structure, there is no large-scale recovery in metallurgy industry. ...
Exploring service quality of low-cost airlines in Europe: An integrated MCDM approach
(Sciendo, 2019)
This study aims to evaluate service quality performance of major LCCs (Low Cost Carriers) in Europe by the MCDM (Multi-Criteria Decision Making) methodology. In addition it focuses on managerial business models and includes ...
Investigation of microstructure and mechanical properties of friction stir welded dissimilar St37/St52 joints
(Institute of Physics Publishing, 2019)
Although friction stir welding (FSW) has widely been applied to aluminum alloys in several industries over the past three decades, it is not yet used in industry for joining of steels. The aim of this study is to characterize ...
Investigating the effect of solid and lightweight hollow block slabs on construction cost
(Ice Publishing, 2019)
In the design of reinforced-concrete buildings, solid and lightweight hollow block slabs are commonly preferred. In general, it is believed that the cost of lightweight hollow block slabs is higher than that of solid slabs. ...
Determination of seasonal metal concentrations in seawater of the Iskenderun Bay in the eastern Mediterranean, Turkey
(Parlar Scientific Publications, 2019)
In this study, seasonal variations of some heavy metal concentrations (Fe, Zn, Cd, Cu, Co, Ni, Al, Mn, Pb, and Cr) were determined. A total of 108 seawater samples were taken in three different stations with depths of about ...
Thiadiazoloquinoxaline and benzodithiophene bearing polymers for electrochromic and organic photovoltaic applications
(Taylor & Francis Ltd, 2019)
Two novel thiadiazoloquinoxaline and benzodithiophene (BDT) bearing copolymers were designed and synthesized. Different BDT units (alkoxy and thiophene substituted) were used as donor materials and the effect of alkoxy and ...
Properties and Corrosion Resistance of AISI H13 Hot-Work Tool Steel with Borided B4C Powders
(Korean Institute of Metals and Materials, 2019)
Abstract: In this study, the surface of AISI H13 steel was borided with powder blends of B4C and NaBF4 using the powder-pack method at 800, 900 and 1000 °C for 2, 4 and 6 h. The structural and mechanical characteristics ...
The Rheology and Performance of Geothermal Spring Water-Based Drilling Fluids
(Wiley-Hindawi, 2019)
In this study, the rheological properties and performances of mud prepared with geothermal spring water to be used by geothermal drilling operators were examined at ambient and elevated temperatures. In this context, mud ...
Artificial sex reversal of white grouper (Epinephelus aeneus) utilizing aromatase inhibitor (Fadrozole)
(Wiley, 2019)
The white grouper is a desirable aquaculture species that adapts to captivity, grows well and commands a high market price. However, little is known about reproductive biology or control of sex reversal of this protogynous ...
Usage of Olivine as Additive Material in Water-Based Drilling Muds
(Parlar Scientific Publications (P S P), 2019)
Drilling is one of the most common methods for the production of fossil fuels or geothermal energy. The success of drilling operations depends on various parameters. One of these parameters is drilling mud. Drilling mud ...
