A central facility concept for nuclear microreactor maintenance and fuel cycle management

Nuclear Engineering and Technology
Commercial deployment of nuclear microreactors presents an opportunity for the industry to rethink its approach to manufacturing, siting, operation and maintenance, and fuel cycle management as certain principles used in grid-scale nuclear projects are ...

Water Markets in Georgia: An Overview of Ongoing Sales of Water [PDF]

, 2003
This paper addresses considerations of direct relevance for ongoing debate in the state as to whether or not water should be sold "like a commodity". The primary point made in the paper is that water is and has long been bought and sold as a commodity in

Transfer function-noise modeling and spatial interpolation to evaluate the risk of extreme (shallow) water-table levels in the Brazilian Cerrados [PDF]

Water regimes in the Brazilian Cerrados are sensitive to climatological disturbances and human intervention. The risk that critical water-table levels are exceeded over long periods of time can be estimated by applying stochastic methods in modeling the ...

Patterns of wild meat and other protein consumption in the periphery of Salonga National Park, Democratic Republic of the Congo

People and Nature, EarlyView.
Abstract In Central Africa, human activities are severely impacting terrestrial and aquatic wildlife, threatening the food security of millions of people. Accordingly, sustainable use of wildlife is crucial for the nutrition and livelihoods of many rural communities in the region.

Comparative Trends of Sociality Among Terrestrial Carnivores: A Multivariate Analysis 陆生食肉动物社会性的比较趋势:一项多变量分析

Wildlife Letters, EarlyView.
In this study we analyze the role of phylogeny, environment, and community structure on sociality. Using structural equation modeling (SEM) we aim to quantify the direct and indirect impacts of variables on behaviors including social grouping, reproduction, and space use among Carnivora species.

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

neonSoilFlux: An R package for continuous sensor‐based estimation of soil CO2 fluxes

Methods in Ecology and Evolution, EarlyView.
Abstract Accurate quantification of soil carbon fluxes is essential to reduce uncertainty in estimates of the terrestrial carbon sink. However, these fluxes vary over time and across ecosystem types and so, it can be difficult to estimate them accurately across large scales.

Tectonics, volcanism, landscape structure and human evolution in the African Rift [PDF]

, 2000
Tectonic movements and volcanism in the African Rift have usually been considered of relevance to human evolution only at very large geographical and chronological scales, principally in relation to longterm topographic and climatic variation at the ...
