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 ...
Comparing the innovation performance of EU candidate countries: an entropy-based TOPSIS approach
(Taylor and Francis Ltd., 2017)
Innovation is important for countries in the competitive global economy. It is one of the main criteria for countries to be superior, to remain competitive, and to produce high technology products. Countries allocate ...
Amino acid and fatty acid composition of freshwater mussels, anodonta pseudodopsis and unio tigridis
(University of Punjab (new Campus), 2018)
Proximate composition, fatty acid and amino acid levels were measured in A. pseudodopsis and U. tigridis from the Lake Golbasi. Crude protein and lipid contents were higher in U. tigridis (10.75%, 0.96%) than in A. ...
Micro-abrasion wear behavior of thermal-spray-coated steel tooth drill bits
(Polish Academy of Sciences, 2016)
Wear behavior of four kinds of thermally sprayed coatings on steel tooth drill bits have been investigated by micro-abrasion wear test. The fixed ball micro abrasion wear test was applied for bare substrate and for thermal ...
Experimental and numerical analysis of a dam-break flow through different contraction geometries of the channel
(MDPI, 2020)
Dam-break wave propagation usually occurs over irregular topography, due for example to natural contraction-expansion of the river bed and to the presence of natural or artificial obstacles. Due to limited available dam-break ...
The determination of the leaching ratios of microdiets containing algae used as direct and indirect in aquaculture
(Taylor and Francis Ltd., 2018)
The purpose of the study was to determine the biochemical compositions and the leaching ratios according to different times (1 minute, 3 minutes, 5 minutes and 15 minutes) of microdiets containing Spirulina sp., Chlorella ...
Novel Metamaterials-Based Hypersensitized Liquid Sensor Integrating Omega-Shaped Resonator with Microstrip Transmission Line
(Mdpi, 2020)
In this paper, a new metamaterials-based hypersensitized liquid sensor integrating omega-shaped resonator with microstrip transmission line is proposed. Microwave transmission responses to industrial energy-based liquids ...
River Flow Estimation Using Artificial Intelligence and Fuzzy Techniques
(MDPI, 2020)
Accurate determination of river flows and variations is used for the efficient use of water resources, the planning of construction of water structures, and preventing flood disasters. However, accurate flow prediction is ...
Proximal probe-like nano structuring in metal-assisted etching of silicon
(American Institute of Physics Inc., 2019)
We use silicon having multiple crystalline orientation domains and high metal doping in metal assisted chemical etching (MACEtch) in HF/H2O2. In device-quality silicon, MACEtch produces high-aspect ratio anisotropic (1-D) ...
Wideband luminescence from bandgap-matched Mg-based Si core-shell geometry nanocomposite
(American Institute of Physics Inc., 2018)
We use wet treatment to integrate red-luminescent Si nanoparticles with Mg-based wide-bandgap insulators Mg(OH) and MgO (5.7 and 7.3 eV respectively). In the process, Mg2+ is reduced on Si nanoparticle clusters, while ...
