Geomorphic patterns, internal architecture and reef growth in a macrotidal, high-turbidity setting of coral reefs from the Kimberley bioregion
The coral reefs of the Kimberley bioregion are situated in an area that is considered a significant ‘biodiversity hotspot’ and are poorly known and of recognised international significance. This paper is a review of ongoing research as part of one of the first geoscientific reef studies of the Kimberley Biozone. Remote sensing, sub-bottom profiling and associated sedimentological work have been employed to produce a regional geodatabase of coral reefs and determine the Holocene internal architecture and growth history of the coral reefs. Satellite image analysis has revealed that fringing reefs in the Kimberley bioregion grow very well and differ geomorphologically from planar reefs both inshore and offshore. The acoustic profiles have depicted multiple reef build-ups, demonstrating the reefs’ long-term resilience. This research has provided a better understanding of the Kimberley reefs and demonstrated their capacity to succeed in challenging environments and generate habitats characterised by high complexity and species diversity

Cervical spine radiculopathy epidemiology: systematic review
Background and objective: Cervical spine radiculopathy (CSR) is a disabling condition that has significant negative impacts on a person's mental health, physical functioning and social participation. Research has reported variable CSR incidence and prevalence among different populations. To date, no systematic review has been completed investigating the prevalence or incidence of CSR; therefore, our objective was to determine the incidence and/or prevalence of CSR in adults. Design and method: A systematic review was conducted including searches of PubMed (MEDLINE), EMBASE and CINAHL from inception to February 25, 2020. Studies including data on incidence and/or prevalence of CSR were included. Methodological quality was assessed using a modified Hayden, Cote and Bombardier appraisal checklist. Data were analysed narratively. Results: Nine low- to high-quality studies were included in the final review. Incidence ranged between 0.832 and 1.79 per 1,000 person-years from two high-quality and one low-quality study. Prevalence values ranged from 1.21 to 5.8 per 1,000 from four medium- to high-quality studies. Prevalence values of 1.14% [95% confidence interval (CI): 0.45–1.82] and 1.31% (95% CI: 0.66–1.96) for males and females, respectively, were reported from one medium-quality study. One medium-quality study reported an unadjusted prevalence value of 6.3% for males and females. Conclusions: This is the first systematic review investigating the epidemiology of CSR in an adult population. This review reports a variable incidence rate and prevalence of CSR among specific populations; however, this was based on nine studies. There is a priority to investigate CSR epidemiology across other populations globally and standardising CSR diagnostic criteria
Regional seasonality of fire size and fire weather conditions across Australia's northern savanna
Australia's northern savannas have among the highest fire frequencies in the world. The climate is monsoonal, with a long, dry season of up to 9 months, during which most fires occur. The Australian Government's Emissions Reduction Fund allows land managers to generate carbon credits by abating the direct emissions of CO2 equivalent gases via prescribed burning that shifts the fire regime from predominantly large, high-intensity late dry season fires to a more benign, early dry season fire regime. However, the Australian savannas are vast and there is significant variation in weather conditions and seasonality, which is likely to result in spatial and temporal variations in the commencement and length of late dry season conditions. Here, we assess the temporal and spatial consistency of the commencement of late dry season conditions, defined as those months that maximise fire size and where the most extreme fire weather conditions exist. The results demonstrate that significant yearly, seasonal and spatial variations in fire size and fire weather conditions exist, both within and between bioregions. The effective start of late dry season conditions, as defined by those months that maximise fire size and where the most extreme fire weather variables exist, is variable across the savannas
Microwave pyrolysis of Laminaria digitata to produce unique seaweed-derived bio-oils
Microwave pyrolysis has become an attractive form of processing technology to generate bio-oil, bio-char and syngas from different biomass feedstocks. In this study, microwave pyrolysis was performed on the UK native seaweed Laminaria digitata and its extract residue from a bio-refinery process. Pyrolysis of these two feedstocks was successfully achieved without the requirement of microwave susceptors, as pelletizing the biomass was sufficient to allow microwave pyrolysis to occur. It was found that average energy requirements as low as 1.84–2.83 kJ g−1 were required to pyrolyse 55–70% of both feedstocks and bio-oil yields of 5–8% and 10–14% for native and extraction residue L. digitata were produced, respectively. Maximum microwave pyrolysis processing times were in the order of 200 s. The bio-oil generated from both feedstocks contained no phenolic based compounds, but a greater number of nitrogen-containing compounds and compounds derived from macroalgal polysaccharides. Yields of certain compounds differed in bio-oils generated from the two L. digitata feedstocks, however it was observed that specific energy did not have a direct influence on bio-oil compound yield. Furthermore, the identification of a particular nitrogen-containing compound L-Proline, 1-methyl-5-oxo-, methylester is thought to be a unique product of microwave pyrolysis when carbon-based additives are avoided

The impact of morphological evolution on hydrodynamics and sediment redistribution of the Western Scheldt estuary from 1200-2020
The Western Scheldt, like many estuaries, faces transitions from natural evolution to artificial adjustments by human interventions. Since the Middle Ages, the latter has caused significant morphodynamic changes; especially continuous land reclamation works and the repeated deepening of navigation channels, remain noticeable today. In the face of present and future sea level rise, there is not only the risk of coastal flooding, but also the possibility of changes in the tidal regime. In this study, we aim to explore the connectivity of historical estuaries, by assessing i) how the morphological changes over time have changed the tidal characteristics, and hence sediment transport; and, ii) the sensitivity of prevailing water levels to dominant wind directions/surges
