Modeling, simulation, and analysis of a reactor system for the generation of white liquor of a pulp and paper industry

open access: yesBrazilian Archives of Biology and Technology, 2011
An industrial system for the production of white liquor of a pulp and paper industry, Klabin Paraná Papéis, formed by ten reactors was modeled, simulated, and analyzed. The developed model considered possible water losses by the evaporation and reaction,

Estimating soil aggregate stability with infrared spectroscopy and pedotransfer functions

open access: yesSoil Security, 2023
Soil aggregate stability is an important indicator of soil condition and is directly related to soil degradation processes such as erosion and crusting.

Surface roughness effects on runoff and soil erosion rates under simulated rainfall [PDF]

open access: yes, 2010
Soil surface roughness is identified as one of the controlling factors governing runoff and soil loss. Yet, most studies pay little attention to soil surface roughness.

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

open access: yes, 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

The Material Basis of 18th‐Century Meissen Porcelain

open access: yesArchaeometry, 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.

Factors for strength attenuation of mudstone during slaking and disintegration

open access: yesYantu gongcheng xuebao, 2019
Slaking, a common engineering characteristic, is the main weathering mode from clay-bearing rocks to soils. Due to the influences of wetting-drying cycles of natural climate, mudstone can slake and disintegrate into the grains with different sizes, which

Loess Studies in Aotearoa New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

Development of laboratory instrumentation for the study of soil erodibility [PDF]

open access: yes, 1968
In order to carry out a study of the relative efficiency of various erodibility indices, and of the relative erodibility of soils developed in the Peak District of Derbyshire (England), three instruments were developed.
