Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

The Anatomical Record, EarlyView.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Comparison of the Effect of Bioglass, Chitosan, and SDF Compounds on Remineralization of Primary Caries Lesions in Primary Teeth: An in vitro Study [PDF]

Journal of Dentistry
Statement of the Problem: Dental caries are among the most common oral and dental diseases affecting adults and children. To prevent caries, either the factors that cause caries should be reduced or the host resistance should be increased.

Fire Histories and Rainforest Aboriginal Archaeology in the Wet Tropics Bioregion, North Queensland

Archaeology in Oceania, EarlyView.
ABSTRACT Unlike the dominant Australian savanna‐sclerophyll vegetation, tropical rainforests do not burn easily. Any evidence of fire in Australian rainforests therefore invites explanations of its source. Analysis of 187 radiocarbon dates that include selected charcoal fragments from 23 soil pits and 7 archaeological sites from the Wet Tropics ...

Semantic primitives and compositionality: An Annual Review of Information Science and Technology (ARIST) paper

Journal of the Association for Information Science and Technology, EarlyView.
Abstract The term semantic primitives refers to a set of basic, atomic concepts from which all other (compound) concepts are constructed. It presupposes the principle of compositionality—the idea that complex items or expressions can be formed by combining simpler constituents.

Multidecadal Changes and Interannual Variation in Springtime Phenology of North American Temperate and Boreal Deciduous Forests

Geophysical Research Letters, 2018
The timing of leaf emergence is an important diagnostic of climate change impacts on ecosystems. Here we present the first continental‐scale analysis of multidecadal changes in the timing of spring onset across North American temperate and boreal forests

Geographical and climatic gradients of evergreen versus deciduous broad‐leaved tree species in subtropical China: Implications for the definition of the mixed forest

Ecology and Evolution, 2017
Understanding climatic influences on the proportion of evergreen versus deciduous broad‐leaved tree species in forests is of crucial importance when predicting the impact of climate change on broad‐leaved forests.

Production of a nutrient enriched biochar: a techno‐economic feasibility analysis

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract A techno‐economic feasibility analysis was conducted for a biomass pyrolysis plant that utilized Eucalyptus to produce fertilizer‐enriched biochar. Key parameters – biomass throughput, fertilizer loading, and selling price – were optimized for financial viability using net present value (NPV), internal rate of return (IRR), return on ...

Deciduous trees are a large and overlooked sink for snowmelt water in the boreal forest

Scientific Reports, 2016
The terrestrial water cycle contains large uncertainties that impact our understanding of water budgets and climate dynamics. Water storage is a key uncertainty in the boreal water budget, with tree water storage often ignored.

Energy recovery from Ginkgo biloba urban pruning wastes: pyrolysis optimization and fuel property enhancement for high‐grade charcoal productions

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Ginkgo biloba trees are widely planted in urban areas of developed countries for their resilience, longevity and aesthetic appeal. Annual pruning to control tree size, shape and interference with traffic and pedestrians generates large volumes of unutilized Ginkgo biomass.
