Surface Rights: Sovereignty, Citizenship and the Question of Mineral Rights in the Woodward Commission

open access: yesAustralian Journal of Politics &History, EarlyView.
ABSTRACT This article retraces the Woodward Commission on Aboriginal Land Rights in the Northern Territory, focusing on the question of mineral rights. Mineral rights were assumed in the Commission's terms of reference and expected by many Aboriginal people. Why, then, were they not recommended by the Commission?

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions

open access: yesArchaeometry, EarlyView.
ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

Photoisomerization-mediated tunable pore size in metal organic frameworks for U(VI)/V(V) selective separation

open access: yesNature Communications
Selective extracting uranium from seawater is quite challenging, particularly the presence of vanadium, which poses a significant obstacle for most amidoxime absorbents.

A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe

open access: yesArchaeometry, EarlyView.
ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).

Electrochemical techniques for uranium extraction from water

open access: yesChemical Engineering Journal
Electrochemical removal of uranium from water is an emerging topic that addresses the treatment of drinking water, remediation of contaminated sites, and mining from seawater. Electrochemical strategies compare favorably to conventional processes, such as adsorption and coagulation/flocculation, with advantages in speed and efficiency, materials ...

Environmental Legitimation in A Global Context: Emerging Market Multinational Enterprises Versus Developed Market Multinational Enterprises

open access: yesBusiness Ethics, the Environment &Responsibility, EarlyView.
ABSTRACT The purpose of this paper is to study the differences and similarities between emerging market multinationals (EMNEs) and developed market multinationals (DMNEs) in their levels of adoption of environmental management policies and environmental disclosure practices when they increase their international diversification.

A New Comprehensive Model to Simulate and Optimize Fluid Flow in Complex Well‐Formation System for In Situ Leaching Uranium

open access: yesEnergy Science & Engineering
In situ leaching (ISL) is an important method for green and efficient development of sandstone‐type uranium ore. It achieves ISL of uranium through the deployment of injection and extraction vertical well patterns.

Cortical‐Hypothalamic Assembloids Uncover the Cortical Regulation of Hypothalamic Responses to Fatty Acid

open access: yesCell Proliferation, EarlyView.
By assembling cortical‐hypothalamic circuits, we show that cortical input protects hypothalamic neurons from fatty acid‐induced damage, which activates PGC1α to boost mitochondrial function. This reveals a cortico‐hypothalamic axis that defends against metabolic stress.
