Physico-chemical and micro-structural behavior of cemented mine backfill: Effect of pH in dam tailings
(Elsevier, 2022)The tailings created during ore processing have been a serious problem for mining companies and environment since it is a challenging task to effectively manage these highly voluminous/dangerous tailings. Therefore, several ... -
Pilot assisted channel estimation for asymmetrically clipped optical OFDM over visible light channels
(Ieee, 2016)The Visible Light Communication(VLC) has drawn significant attention recently for wireless communication in addressing the performance limitations of wireless systems due to the scarcity of bandwidth. in VLC system, the ... -
Plant biomass: insights from imaging cell walls using molecular probes
(2016)Cell walls are an important and growing subject of research in plant biology. In the last decade, there has been an increasing interest in using cell walls as feedstock for the production of second generation biofuels. ... -
Polymer shape effect on damage evolution, internal defects and crack propagation of 3D-printed polymer-based cementitious backfill
(Elsevier, 2023)The strength property and damage mode of cementitious tailings backfill (CTB) are governed by its structural characteristics in the presence of the microstructure/internal defect effects. However, this correlation is still ... -
Polypropylene fiber effect on flexural strength, toughness, deflection, failure mode and microanalysis of cementitious backfills under three-point bending conditions
(MDPI, 2023)Cemented tailings backfill (CTB) is continually practiced in a large number of metallic mines for re-filling underground ore extraction areas. Re-filling these areas can boost the security of mining teams during construction. ... -
Polypropylene fiber's effect on the features of combined cement-based tailing backfill: Micro- and macroscopic aspects
(MDPI, 2024)In undercut-and-fill mining, backfills show weak tensile strength and poor ductility properties since they act as artificial pillars to support stope roofs. Hence, the enhancement of the stability of mining structures and ... -
Positioning of leakages in underwater natural gas pipelines for time-varying multipath environment
(Pergamon-Elsevier Science Ltd, 2020)Underwater natural gas pipelines (UNGPs) used to typically transport natural gas, which is a very important energy resource, can be punctured due to various reasons such as corrosion and shipping/fishing activities. ... -
Post-variscan autochthonous cover in the eastern Sakarya zone, Turkey: evolution of the late carboniferous back-arc ocean to the triassic Karakaya Ocean
(Elsevier, 2023)The processes that caused removal of the upper Carboniferous to Permian sediments in the eastern Sakarya Zone, Turkey, are modeled by using of geochemical data and LA-ICP-MS U-Pb ages from detrital zircons. A felsic ... -
Postcollisional transition from subduction- to intraplatetype magmatism in the eastern Sakarya zone, Turkey: Indicators of northern Neotethyan slab breakoff
(Geological Soc Amer, Inc, 2019)Postcollisional magmatism in the eastern Sakarya zone was recorded by voluminous basic volcanism and repeated plutonism during the early Cenozoic. the temporal and geochemical evolution of these magmatic rocks is important ... -
Pozzolanic properties of trachyte and rhyolite and their effects on alkali-silica reaction
(Techno-Press, 2021)The alkali-silica reaction (ASR) is a highly complex chemical reaction which causes damage to concrete and thus adversely affects the durability and service life. Significant damage can occur in concrete structures due to ... -
Predicting long-term impact of cementitious mine fill considering sand as a copper-tailings substitution
(Elsevier, 2023)It is of great importance to use different materials or techniques to enhance the quality/behavior of cementitious mine fill (CMF). This leads the mining industry to evaluate new production techniques or resources that ... -
Predicting mechanical properties in geopolymer mortars, including novel precursor combinations, through XGBoost method
(Springer, 2024)Concrete is the most widely used material in the building industry due to its affordability, durability, and strength. However, considering carbon emissions, it is believed that concrete will be replaced by geopolymers in ... -
