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

open access: yesArchaeology 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 ...

"Meta Interpretation": A Method for the Interpretive Synthesis of Qualitative Research

open access: yesForum: Qualitative Social Research, 2005
Recognition of the need for good research synthesis dates back almost half a century (c.f .WRIGHT MILLS, 1959), although it is far more recently that specific methods of synthesis have been developed.

An investigation into the relationship between preceding break crops and weed populations in barley crops in organic ley/arable rotations [PDF]

open access: yes, 2002
This report was presented at the UK Organic Research 2002 Conference. The relationship between weed populations and cereal crops following nine organic break crops was investigated in field trials in Warwickshire, Aberdeenshire and Ceredigion in 2001 ...

Predicting spring barley yield from variety-specific yield potential, disease resistance and straw length, and from environment-specific disease loads and weed pressure [PDF]

open access: yes, 2008
For low-input crop production, well-characterised varieties increase the possibilities of managing diseases and weeds. This analysis aims at developing a framework for analyzing grain yield using external varietal information about disease resistance ...

Usage of the term provenance in LIS literature: An Annual Review of Information Science and Technology (ARIST) paper

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract Provenance is the story of how something has come to be. In this paper, we provide a systematic literature review to categorize the various notions of provenance in Information Sciences. The goal of this review is to paint a broader picture of the multiple uses of provenance at play and to enhance our understanding of the importance of ...

Mobilizing mine lands for biobased decarbonization strategies

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Over 163 000 ha of mine lands in Pennsylvania (PA) have the potential to produce willow as a feedstock for renewable energy generation. Each year these lands could produce between 454 000 and 907 000 dry Mg of willow, which can be a feedstock for bioenergy (i.e., biopower) with carbon capture and sequestration (BECCS) or sustainable aviation ...

Nitrogen and weed management in transplanted tomato in the Nigerian forest-savanna transition zone [PDF]

open access: yes, 2018
Weed infestation and inherent low soil fertility are among primary reasons for low yields of tomato in Nigeria. Field trials were carried out during the wet season of 2015 and 2016 to evaluate yield response of tomato to nitrogen (N) application and weed

A novel treatment of biogas digestate waste for biochar production and its adsorption of methylene blue and malachite green in a binary system

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study presents a novel treatment of biogas digestate to produce biochar at processing temperatures of 500–700 °C. The resulting biochar was applied for the simultaneous removal of methylene blue (MB) and malachite green (MG) in a binary system.
