Identifying appropriate conditions for producing spindle-like causticizing precipitated calcium carbonate for paper filler applications [PDF]

BioResources, 2012
Causticizing precipitated calcium carbonate (CPCC) as a by-product of the green liquor causticizing process can be used as paper filler to save resources and reduce costs.

An approach for characterising the weathering behaviour of Flysch slopes applied to the carbonatic Flysch of Alicante (Spain) [PDF]

, 2014
Various studies indicate that most of the slope instabilities affecting Flysch heterogeneous rock masses are related to differential weathering of the lithologies that make up the slope. Therefore, the weathering characteristics of the intact rock are of

Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates

Land Degradation &Development, EarlyView.
ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...

Reclaimed Well Sites on Salt Affected Soils: Electrical Conductivity and Sodium Adsorption Ratio as Plant Community Response Indicators

Land Degradation &Development, EarlyView.
ABSTRACT Salt affected soils are common worldwide, resulting from natural causes and anthropogenic activities. Saline and sodic soils often occur in association with oil and gas production, impacting soil properties which can impede vegetation growth and development.

Landslides induced by slaking of geomaterial

MATEC Web of Conferences, 2018
The geological event that happens because of an unbalance between shear strength and shear stress on rock mass is known as a landslide. This usually occurs due to improper handling of the exposed material.

“Flames Over Persepolis”: New Scientific Evidence Supporting Historical Perspectives

Archaeometry, EarlyView.
ABSTRACT This study investigates the burning of Persepolis Terrace, historically attributed to Alexander III in 330 bce. A review of classical accounts and excavation reports, combined with diagnostic surveys, confirms the fire's historicity and provides novel insights.

Taya Caves, a Buddhist marvel hidden in underground Japan: stone properties, deterioration, and environmental setting

Heritage Science, 2020
The Buddhist sacred site of Taya Caves is a gem hidden underground in Yokohama, Japan. The caves were excavated and sculpted into bare rock by Shingon Buddhist monks from the Kamakura until the Edo period (thirteenth–nineteenth century), and dedicated to

The Material Basis of 18th‐Century Meissen Porcelain

Archaeometry, EarlyView.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Experimental investigation of the influence of the growth of saprotrophic fungi (Pleurotus ostreatus) on the aggregate stability of a silty sand [PDF]

E3S Web of Conferences
Granular soils are highly susceptible to erosion, a process that may contribute to slope instability. For example, gully erosion promotes preferential flow and toe erosion, eventually leading to undercutting and slope failure. Given that soil erodibility

Severity of Betel Quid Use Disorders (BUD) Among Adult Indian Betel Quid Chewers

Oral Diseases, EarlyView.
ABSTRACT Objective Oral cancer is a major public health problem in India, with the highest number of cases and deaths in the world, and Betel Quid (BQ) chewing is responsible for almost 50% of cases. BQ Use Disorder (BUD) prevalence and severity have never been investigated among Indian BQ chewers.
