Khorvash, M., Colombatto, D., Beauchemin, K. A., Ghorbani, G. R. and Samei, A. 2006. Use of absorbants and inoculants to enhance the quality of corn silage. Can. J. Anim. Sci. 86: 97–107. This study examined whether inoculants and various absorbent materials could be used during ensiling to reduce effluent losses and improve nutritive value of corn silage. Two corn forages were harvested: conve...

Abstract Understanding the mechanisms of strain localization leading to brittle failure in reservoir rocks can shed light on geomechanical processes such as porosity and permeability evolution during rock deformation, induced seismicity, fracturing, subsidence geological reservoirs. We perform triaxial compression tests three types porous reveal local deformation that control system-size failur...

for obtaining reservoir petrophysical properties, for example porosity, non-destructive methods such as x-ray computed tomography, ct, seems to be precise and accurate. porosity is deducted from the ct image with a single scan via different techniques, such as pore space detection by image segmentation techniques then correlation with porosity. more than one hundred samples with carbonate li...

Historically, the Everglades Agricultural Area (EAA) evolved under seasonally-flooded conditions that predominately supported sawgrass and other wetland vegetation. Over several thousand years, Histosol “muck” soils were deposited as organic matter accumulated above the limestone (calcium carbonate) bedrock. In the early 1900s, these soils were drained. Declining water table levels coupled with...

Inherent dangers in mining operations motivate the use of robotic technology for addressing hazardous situations that prevent human access. In the context of this case study, we examine the application of a robotic tool for map verification and void profiling in abandoned limestone mines for analysis of cavity extent. To achieve this end, our device enables remote, highly accurate measurements ...

UPV as non-destructive technique can effectively contribute to the low invasive in situ analysis and diagnosis of masonry elements related to the conservation, rehabilitation and strengthening of the built heritage. The use of non-destructive and non-invasive techniques brings all the times many advantages in diagnostic activities on pre-existing buildings in terms of sustainability; moreover, ...

The objective was to quantify how the concentration and particle size of unreacted “residual” limestone affected pH buffering capacity for ten commercial and nine research container substrates that varied in residual calcium carbonate equivalents (CCE) from 0.3 to 4.9 g CCE·L. The nine research substrates contained 70% peat:30% perlite (by volume) with dolomitic hydrated lime at 2.1 g·L, follow...

Fully automated online measurement of the size distribution of limestone fragments on conveyor belt is presented based on 3D range data collected every minute during 13 hours of production. The research establishes the necessary measurement technology to facilitate automatic control of particle breaking or aggregating processes to improve both energy efficiency and product quality. Techniques a...

Introduction. The current hypothesis is that Martian sinkholes do not exist. It is proposed that the low pH environment resulting from the high CO2 content of the atmosphere will cause calcium carbonate to be deposited as calcite cemented sandstone rather than limestone [5]. Calcite, as well as gypsum, halite, smectite and illite, has been detected in Martian meteorites providing proof of the p...
