Nationalism and Education in the Arctic: A Study of Greenland in the Context of the Kingdom of Denmark

Nations and Nationalism, EarlyView.
ABSTRACT This article analyses the coconstitution of nationalism and education in Greenland (Kalaallit Nunaat) within the Kingdom of Denmark. Drawing on Ernest Gellner, Benedict Anderson, Michael Billig and Siniša Malešević, it argues that schooling standardises language, history and civic repertoires, thereby fabricating the modern national subject ...

Alternative approaches to dryland reclamation enhance vegetation cover and soil stability at a former uranium mine

Restoration Ecology, EarlyView.
Abstract Introduction Conventional reclamation methods to recover dryland ecosystems after mineral extraction often have low success. Alternative reclamation techniques may help overcome the many challenges to establishing persistent native vegetation and stable soils.

Sequencing of the rus gene before and after the mutation with DES in the bacterial Acidithiobacillus sp. FJ2

یافته‌های نوین در علوم زیستی, 2019
In Acidithiobacillus ferrooxidans, the proteins present in the electron transfer pathway cause ferrous iron oxidation which leads to uranium extraction. The relationship between gene sequence and uranium extraction has not been investigated yet. Based on

Solvent Extraction of Uranium Using Alkylamines

Journal of the Atomic Energy Society of Japan / Atomic Energy Society of Japan, 1963
The new conversion refining process using high molecular weight alkylamines was developed in order to obtain directly highly purified UF4 or UO3 from ore leaching solution without the precipitation process of yellow cake. Suitable conditions for each of the extraction, conversion and stripping process were described, and also the flow diagram of this ...

Conditions and timing for the precipitation of early marine diagenetic dolomite in the Triassic Dolomia Principale (northern Italy)

Sedimentology, EarlyView.
ABSTRACT Thermodynamic constraints and empirical evidence often suggest that fabric‐retentive replacement dolomites are stable carbonate minerals that preserve ancient seawater properties. This study evaluates this hypothesis by examining the Upper Triassic Dolomia Principale in Northern Italy.

Rare Earth Element Potential in the Araí Rift Metavolcanic, Central Brazil: Gamma‐Ray Signatures, Mineralogy and Exploration Implications

Terra Nova, EarlyView.
ABSTRACT Although central Brazil hosts significant ion‐adsorption rare earth element (REE) deposits associated with A‐type granites, their coeval volcanic counterparts have been largely overlooked as exploration targets. This study demonstrates that acidic metavolcanic rocks of the Araí Group share strong radiometric, geochemical and mineralogical ...

To the question of the intensification of the processes of uranium extraction from refractory raw materials

Metalurgija, 2019
Recently, one of the main directions for increasing the extraction of uranium from difficult-to-hide ores is the use of intensifiers, which allow the most complete transfer of uranium from one valence state to another. In the article, the catalyst “M-1”,
