Georeferencing of the Nile River in Piri Reis 1521 map, using artificial neural network method
(Springer, 2019)
For many years, the adaptation of the historical maps to those used today has been one
of the felds of study of cartography and geodesy. In this process, the frst problem is that
the coordinate system in historical maps ...
Effect of hydrocarbon chain length on adsorption of cationic surfactants onto clinoptilolite
(Elsevier, 01.01.2003)
The adsorption behavior of quaternary ammonium cationic surfactants with different
hydrocarbon chain lengths, i.e. HDTMA (hexadecyltrimethylammonium), TDTMA (tetradecyltrimethy-
lammonium) and DDTMA (dodecyltrimethylammonium), ...
Effects of La2O3 addition on the thermal stability of γ-Al2O3 gels
(Elsevier, 01.01.2004)
The effects of La2O3 additions up to 5 wt.% on the thermal stabilities of sol-gel derived alumina gels were studied. Observations
were made on pore size, total pore area, phase changes at various sintering temperatures ...
Experimental and statistical evaluation of cutting methods in relation to specific energy and rock properties
(Springer, 2013)
In a processing plant, natural stone can be cut by methods such as circular sawing (CS), frame sawing (FS), water jet cutting (WJC) and abrasive water jet cutting (AWJC). The efficiency of cutting systems can be compared ...
Development of efflorescence control methods of fly ash based foam geopolymers
(ICIVILTECH Afyonkarahisar, 2020)
Since the environmental impacts of carbon emissions due to the cement production have started to be discussed, an alternative material has been sought. Geopolymers are new generation materials which are good candidates to ...
Adsorption of Cr(VI) Ions on Magnetite Nano-Particles (Fe3O4): Kinetic and thermodynamic studies
(El-Cezerî Journal of Science and Engineering, 01.10.2016)
This article intends to investigate the kinetic and thermodynamic properties of adsorption process of hexavalent chromium [Cr(VI)] ions on magnetite nano-particles (Fe 3 O , MNPs). In accordance with this purpose, MNPs ...
Determination of actual dissolution rates from some rock properties in construction of deep salt cavern for natural gas storage
(Elsevier, 2020)
Available energy resources should be efficiently used to meet the global energy demand. The storage of energy resources, especially as natural gas, is important to balance extreme fluctuations in demand and supply of energy. ...
Data mining techniques for the prediction of Bohme surface abrasion rates from rock properties
(ASTM International, Ocak 2020)
Abrasion refers to the wearing down of rock surfaces due to abrasive grains. Abrasion resistance
refers to the ability of rocks to withstand wear. Abrasion resistance is used to determine
the resistance of building ...
Colloidal stability-slip casting behavior relationship in slurry of mullite synthesized by the USP method
(Elsevier, 30.07.2011)
This
study presents the outcome of a research concerning the relationship between the colloidal stability of mullite powders synthesized by the
USP
(ultrasonic spray pyrolysis) method and its slip casting behavior. ...
Effect of pH and polymer charge density on settling rate and turbidity of natural stone suspensions
(Elsevier, 02.02.2005)
In the present paper, the effects of suspension pH and charge density of anionic polyacrylamide (PAA) on flocculation
behavior of two different natural stone suspensions (NSS) marble and travertine were investigated by ...
