Stochastic model for crop water stress during agricultural droughts

open access: yesEngineering Reports, 2019
The increasing occurrence of severe droughts and sparse rainfall due to climate change is resulting in high and costly demand for water resources. A greater understanding of uncertainties associated with the creeping occurrence of agricultural drought ...

Effect of Coarse Aggregate Sizes and Replacement Levels on the Strength of Palm Kernel Shell (PKS) Concrete [PDF]

open access: yes, 2013
The maximum coarse aggregate size used in concrete can impact on its strength. An investigation of the effect of coarse aggregate size and replacement level of granite with palm kernel shell (PKS) on the compressive and tensile strengths of PKS concrete ...

Application of Ti-in-zircon thermometry to granite studies: problems and possible solutions

open access: yesContributions to Mineralogy and Petrology, 2019
The application of the Ti-in-zircon thermometer to granitic rock requires consideration of $$a_{{{\text{TiO}}_{2} }}$$aTiO2 and $$a_{{{\text{SiO}}_{2} }}$$aSiO2 during zircon crystallization.

AE Characteristics of Rockburst Tendency for Granite Influenced by Water Under Uniaxial Loading

open access: yesFrontiers in Earth Science, 2020
In deep mining, granite is stored with high energy duing to its structural integrity and brittleness. Rock bursts usually occur because stress changes and mining disturbances during mining, which seriously threaten safe production. Focusing on the factor

Laboratory testing and numerical simulation of properties and thermal-induced cracking of Eibenstock granite at elevated temperatures

open access: yesActa Geotechnica, 2020
The knowledge about thermo-mechanical properties of granite is still limited to some extent. Individual measurements are necessary to obtain reliable properties for specific granite types.
