Effect of mineral additives to a gypsum wet deformation [PDF]

open access: yesE3S Web of Conferences, 2021
The influence of mineral additive, i.e. ground granulated blast-furnace slag on artificial gypsum stone humidity strains has been studied. The slag content was varied in the range from 0 to 0.33 by weight based on the total amount of the mixture.

Functional, inflammatory and interstitial impairment due to artificial stone dust ultrafine particles exposure [PDF]

open access: yesOccupational and Environmental Medicine, 2019
Objective Artificial stone dust (ASD) contains high levels of ultrafine particles (UFP <1 µm) which penetrate deeply into the lungs. This study aimed to demonstrate the direct effect of UFP in the lungs of ASD-exposed workers on functional inflammatory and imaging parameters.

Effect of calcium lignosulfonate on the deformation and failure characteristics of cementing stone and its modification mechanism

open access: yesMeitan xuebao, 2023
In the coalbed methane extraction of surface wells in the mining area, the mining of coal seam in working face will cause a significant disturbance to overlying rock layer, which in turn will lead to the deformation and damage of surface wells.

Feed particle selection and nutrient intake altered by pecking stone consumption and beak length in free-range laying hens

open access: yesAnimal Nutrition, 2019
The present study investigated the effects of pecking stones on feeding behaviour of hens from 16 to 46 weeks of age. Eighteen flocks of Hy-Line Brown hens were housed in 2 commercial free-range housing systems.

Energy spectra of 3He-rich solar energetic particles associated with coronal waves

open access: yes, 2016
In addition to their anomalous abundances, 3He-rich solar energetic particles (SEPs) show puzzling energy spectral shapes varying from rounded forms to power laws where the later are characteristics of shock acceleration. Solar sources of these particles

The food niche overlap of five fish species in the Úpoř brook (Central Bohemia)

open access: yesKnowledge and Management of Aquatic Ecosystems, 2013
The diet and food niche overlap of five fish species in the Úpoř brook was evaluated. The supply of food represented by benthos was studied, and the proportion of total food particles in the intestine of brown trout Salmo trutta L ...

Combined DEM-FDM modelling of encased stone column [PDF]

open access: yesE3S Web of Conferences, 2019
Combination of the continuum-based numerical methods and the discrete element method (DEM) could be a powerful way of simulating complex problems. This approach benefits from the capabilities of both methods.
