The effect of the frequency of prescribed burning on annual soil carbon balance in a loblolly-shortleaf pine forest in East Texas Open
Prescribed burning is a common forest management tool, and is expected to affect soil carbon (C) content and dynamics, yet data on this remain limited. Here we report the effect of prescribed burning frequency on net soil C balance in thre…

Simplified measurement and verification combined with quality assurance instruments: a more practical and accessible method for M&V of energy savings Open
Energy efficiency (EE) is our “first fuel” and an essential resource in reaching climate goals, reducing dependence on fossil fuels, increasing security of supply, and many other “Multiple Benefits.” However, by their nature, savings are i…

Reaction dynamics and early-time behaviour of chemical decontamination Open
When a hazardous chemical soaks into a porous material such as a concrete floor, it can be difficult to remove. One approach is chemical decontamination, where a cleanser is added to react with and neutralise the contaminating agent. The g…

Preliminary vegetational changes in frequently burned and unburned upland pine-hardwood forests at Cook’s Branch Conservancy in Montgomery County, Texas, U.S.A. Open
Vegetational changes over a 6-year period (2012 to 2017) were recorded in upland pine – hardwood forests on Cook’s Branch Conservancy (CBC) in Montgomery County, Texas, using permanent vegetation monitoring plots as a basis for following f…

On steady natural convection in a vertical porous slab with permeable boundaries Open
In this paper, we consider the steady-state base flow for natural convection in a vertical porous slab with permeable boundaries. Although recent work proposed a one-dimensional solution for this flow, we make a strong case for this flow t…

Safe Storage of Sugar Bagasse Open
In this report we investigate the thermal evolution in a one-dimensional bagasse stockpile. The mathematical model is taken from the work of Gray et al. and involves four unknowns, the temperature, oxygen, liquid water and water vapour. We…

Rough or Smooth Balls? That is the Question Open
The question posed at the study group, by a South African premiership team based in Johannesburg, was basically, ‘Can we choose a match ball that will disadvantage opponents?’ In this report we answer the question through focussing on the …

A validated asymptotic thermomechanical model for air-gap formation in tapered moulds in the continuous casting of steel Open
A recent asymptotics-based thermomechanical model is adapted and applied to the mould region in the continuous casting of round steel billets, with a view to describing the complex interplay between air-gap formation, mould taper, cooling …

On small-time similarity-solution behaviour in the solidification shrinkage of binary alloys Open
In the one-dimensional solidification of a binary alloy undergoing shrinkage, there is a relative motion between solid and liquid phases in the mushy zone, leading to the possibility of macrosegregation; thus, the problem constitutes an in…

Analysis of a model for the formation of fold-type oscillation marks in the continuous casting of steel Open
This paper investigates the different possible behaviours of a recent asymptotic model for oscillation-mark formation in the continuous casting of steel, with particular focus on how the results obtained vary when the heat transfer coeffic…

Office building deep energy retrofit: life cycle cost benefit analyses using cash flow analysis and multiple benefits on project level Open
Deep energy retrofit (DER) of the existing building stock is a meaningful strategy to reduce fossil fuel consumption and CO2 emissions. However, the investment volumes required to undertake DER are enormous. In Europe, cumulative demand fo…

On the formation of fold-type oscillation marks in the continuous casting of steel Open
Asymptotic methods are employed to revisit an earlier model for oscillation-mark formation in the continuous casting of steel. A systematic non-dimensionalization of the governing equations, which was not carried out previously, leads to a…

An asymptotic analysis of the laminar-turbulent transition of yield stress fluids in pipes Open
The work in this paper concerns the axisymmetric pipe flow of a Herschel-Bulkley fluid, with the aim of determining a relation between the critical velocity (defining the transition between laminar and turbulent flow) and the pipe diameter…

A model of flow in a sugar diffuser Open
In the sugar industry a major component of the extraction process is a device known as a diffuser. Crushed and shredded cane is repeatedly washed by warm water as it travels along a conveyor, leaching the sugar from the cane. An important …
