3D Numerical Investigation Of Ground Settlements Induced By Construction Of Istanbul Twin Metro Tunnels With Special Focus On Tunnel Spacing
(2019)
One of the most important considerations of tunneling in urban areas is controlling the amount of surface settlement that occurs during construction stages. The goal of this paper is to investigate the effect of spacing ...
Evaluation Of The Alternatives For Gold Ore Grinding Circuits By Using Of Laboratory Studies Results And Simulation Method; Case Study: Iranian Gold Co
(2019)
In this study, simulation aided design of grinding circuit for a gold mine in Iran is presented. The main parameters for the design of the grinding circuit are the ore specifications and the considered operating conditions. ...
Estimating Specific Energy From The Brittleness Indexes In Cutting Metallic Ores
(Southern African Inst Mining Metallurgy, 2016)
Specific energy (SE) is a very useful parameter for assessing rock excavation by machine. Predicting the SE from the brittleness will be practical, especially for preliminary studies, due to the fact that determining the ...
Metaheuristic Kriging: A New Spatial Estimation Method
(Hacettepe University, 2017)
Kriging is one of the most widely used spatial estimation method. In
kriging estimation, weights assigned to the neighboring data are determined by minimizing the estimation error variance (EEV). Due to
the minimization ...
Controlled Synthesis, Characterization And Thermal Properties Of Mg2B2O5
(De Gruyter Poland Sp Zoo, 2010)
Optimum conditions for synthesizing monoclinic and triclinic Mg2B2O5 compounds by high-temperature solid-state reactions were investigated. Mixtures composed of boric acid and magnesium oxide at MgO:B2O3 mole ratios of ...
Examining The Effect Of Adverse Geological Conditions On Jamming Of A Single Shielded Tbm In Uluabat Tunnel Using Numerical Modeling
(CSRME, 2017)
Severe shield jamming events have been reported during excavation of Uluabat tunnel through adverse geological conditions, which resulted in several stoppages at advancing a single shielded tunnel boring machine (TBM). To ...
Effect of Acidulated Phosphate Fluoride and Casein Phosphopeptide-Amorphous Calcium Phosphate Application on Shear Bond Strength of Orthodontic Brackets
(E H Angle Education Research Foundation, Inc, 2008)
Objective: To evaluate the effect of a recently introduced prophylactic agent, casein phospho-peptide-amorphous calcium phosphate (CPP-ACP), on shear bond strength of brackets and compare it with the effect of acidulated ...
Modelling Electrical Conductivity Of Groundwater Using An Adaptive Neuro-Fuzzy Inference System
(Pergamon-Elsevier Science Ltd, 2006)
Electrical conductivity is an important indicator for water quality assessment. Since the composition of mineral salts affects the electrical conductivity of groundwater, it is important to understand the relationships ...
Effects of A Fluoride-Containing Casein Phosphopeptide-Amorphous Calcium Phosphate Complex on The Shear Bond Strength of Orthodontic Brackets
(Oxford Univ Press, 2012)
The purpose of this study was to investigate the effects of enamel pre-treatment with a new fluoride-containing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) complex on the shear bond strength (SBS) of brackets ...
Interaction Of Celestine Concentrate And Reagent Grade Srso4 With Oxalate Solutions
(Berg Fac Technical Univ Kosice, 2012)
The interaction of reagent grade strontium sulphate and celestine concentrate with aqueous solutions of oxalic acid, sodium oxalate and ammonium oxalate for the production of strontium carbonate were investigated for ...
