RCUK policy on open access: Swansea University compliance report 1st April 2015 to 31st July 2016

This Open Access compliance report has been produced to supplement the annual block grant data returned to Research Councils UK (RCUK) by Swansea University. The block grant is provided by RCUK over a five year period to support Gold Open Access for peer-reviewed research articles published in journals or conference proceedings. Since the revised RCUK policy on Open Access was implemented in 2013, Swansea University has received an allocation to facilitate open access through the payment of article processing charges (APCs). This report gives an overview on progress at the institution for implementing the Open Access policy

The compressible granular collapse in a fluid as a continuum: validity of a Navier-Stokes model with μ(J)\mu(J)-ϕ(J)\phi(J)-rheology

The incompressible $\mu(I)$-rheology has been used to study subaerial granular flows with remarkable success. For subaquatic granular flows, drag between grains and the pore fluid is substantially higher and the physical behaviour is more complex. High drag forces constrain the rearrangement of grains and dilatancy, leading to a considerable build-up of pore pressure. Its transient and dynamic description is the key to modelling subaquatic granular flows but out of the scope of incompressible models. In this work, we advance from the incompressible $\mu(I)$-rheology to the compressible $\mu(J)$-$\phi(J)$-rheology to account for pore pressure, dilatancy, and the scaling laws under subaquatic conditions. The model is supplemented with critical state theory to yield the correct properties in the quasi-static limit. The pore fluid is described by an additional set of conservation equations and the interaction with grains is described by a drag model. This new implementation enables us to include most of the physical processes relevant for submerged granular flows in a highly transparent manner. Both, the incompressible and compressible rheologies are implemented into OpenFOAM and various simulations at low and high Stokes numbers are conducted with both frameworks. We found a good agreement of the $\mu(J)$-$\phi(J)$-rheology with low Stokes number experiments, that incompressible models fail to describe. The combination of granular rheology, pore pressure, and drag model leads to complex phenomena such as apparent cohesion, remoulding, hydroplaning, and turbidity currents. The simulations give remarkable insights into these phenomena and increase our understanding of subaquatic mass transports

Evaluating Strategies for Anemone and Ranunculus Cut Flower Production in the US Intermountain West

National growth in small-scale, specialty cut flower farms is reflected in Utah, where 145 members have joined the Utah Cut Flower Farm Association since its 2019 founding. Cool season cut flower production is limited in Utah and the Intermountain West by a narrow harvest window and elevated soil salinity. The objective of this research was to optimize production systems for anemone (Anemone coronaria L.) and ranunculus (Ranunculus asiaticus L.) in the Intermountain West by evaluating season advancement methods within a high tunnel and field production system, as well as the salinity sensitivity of each species. Fall planting dates, combinations of low tunnels and straw mulch, pre-sprouting, and cultivars were trialed in North Logan, UT from 2019 to 2022. Up to four cultivars of anemone tubers and ranunculus tuberous roots were presprouted or directly planted into a high tunnel (left bare or covered with low tunnels) or field (left bare or covered with mulch, a low tunnel, or mulch and a low tunnel) from November to April and evaluated for harvest timing, yield, stem quality, and profitability. Additionally, anemone and ranunculus were grown in pots in a greenhouse, irrigated with nutrient solutions with electrical conductivities (EC) from 0.5 dS·m-1 to 5.5 dS·m-1 for eight weeks, and evaluated for growth, yield, and gas exchange parameters to determine their salinity sensitivity. For anemone, planting pre-sprouted tubers under low tunnels in the high tunnel in November delivered the earliest harvest (2 Mar.), greatest marketable yield (280 stems per m2), and greatest net returns ($38 per m2), with 32$54 per m2), with 39% greater marketable yield for ‘LaBelle’ than ‘Amandine.’ In the salinity trial, visual quality, plant growth, and net photosynthesis decreased when plants were irrigated with EC 2.5 dS·m–1 and above, indicating that the irrigation salinity tolerance threshold for both anemone and ranunculus is likely between 0.5 and 2.5 dS·m–1. High-yielding cultivars, pre-sprouting, fall-planting in high tunnels with frost cloth, and managing soil salinity are recommended for Intermountain West anemone and ranunculus growers

Ranunculus Cut Flower Production in Utah

Ranunculus (Ranunculus asiaticus) is grown as a cool-season annual for cut flower production in Utah. Tuberous roots can be planted as early as November in a high tunnel for blooms beginning in April. For field production, plant in November with insulation or as early as possible in spring for blooms beginning in May. Flower production ceases when temperatures reach approximately 80°F, usually by early July in northern Utah. In North Logan, UT, high tunnels produced an average of 3 to 7 marketable stems per plant, compared to 1 to 2 stems per plant in the field. Profit potential is high when grown in a high tunnel and sold wholesale compared to other Utah-grown cut flowers

Anemone Cut Flower Production in Utah

Anemone (Anemone coronaria) is grown as a cool-season annual for cut flower production in Utah. Tubers can be planted as early as November in a high tunnel for blooms beginning in March. For field production, plant in fall with insulation or as early as possible in spring (i.e., the soil is workable, approximately early March) for blooms beginning in May. Flower production ceases when temperatures reach approximately 80°F, usually by early July in northern Utah. In North Logan, UT, high tunnels produced an average of 2 to 7 marketable stems per plant, compared to 1 to 4 stems per plant when field grown. Anemone is popular with florists for use in spring arrangements. Its wholesale profit potential is moderately high compared to other Utah grown-cut flowers
