This gazette presents to the reader outside Rome news of recent archaeological activity (July 2023–July 2024) gleaned from public lectures, conferences, exhibitions and newspaper reports.
With the growing global population and climate change, achieving food security is a pressing challenge(1). Vertical farming has the potential to support local food production and security. In the UK population females and younger adults appear to be particularly vulnerable to micronutrient shortfalls from food sources alone. Levels of micronutrient intakes including zinc and iron are below the recommended daily intake(2). As a Total Controlled Environment Agriculture (TCEA) system, vertical farming employs hydroponics using a nutrient solution which offers opportunities to modulate nutrient uptake, and thus influence plant mineral and vitamin composition(3).
In this study we aimed to determine the suitability of different crop types for soilless agronomic biofortification with zinc and iron to achieve biofortified crops.
In this study, we investigated the effect of the addition of 20ppm (+20 mg L−1) of zinc (ZnSO4) or iron (Fe-EDTA) to the nutrient solution on the growth and nutritional components in pea microgreens, kale microgreens and kale baby leaf plants. The growth conditions were kept identical throughout the treatments with photoperiod 18 h d-1, temperature 20-22°C and relative humidity at 70-80%. Plant growth, mineral composition, glucosinolate content and protein content were evaluated. Results were analysed using ANOVA (p<0.05, Tukey’s test).
It was determined that higher amounts of zinc in the nutrient solution resulted in significantly higher levels of zinc in all three crops (p<0.05), with increases of 205% in pea microgreens, 264% in babyleaf kale and 217% in kale microgreens compared to the control plants. Higher amounts of iron in the nutrient solution resulted in significantly higher levels of iron only in pea microgreens, with an increase of 38% (p<0.05). Neither dosing regimen negatively influenced the overall crop performance.
These results suggest that the three different crops are suitable for soilless biofortification with zinc and iron, although pea microgreens were the only crop that had a significant increase in iron upon iron-dosing.
This state-of-the-art paper begins to unpack the concept of a housing crisis. Whilst it may be a useful starting point in recognising the presence of problems within UK housing provision and allocation, its generic and umbrella coverage papers over the diversity of experiences. Similarly, as a concept it neither suggests the causes of the crisis nor possible solutions. With this in mind, this paper explores commodification within housing and uses this to recognise that our relationship to housing and our relationship to the crisis, can be shaped by our relationship to capital. However, the paper takes this further by arguing that the presence of vulnerability should also be borne in mind when considering commodification, where vulnerability includes experiences of discrimination, mental health, and legal status.
This article evaluates a potential angelomorphic tradition in Acts 12.15c. It demonstrates that the most common interpretation of the phrase ὁ ἄγγελός ἐστιν αὐτοῦ (‘it is his angel’, 12.15c) as referring to Peter’s guardian angel fails to account adequately for the evidence. After surveying several different proposals for interpreting the phrase, it argues that angelomorphy/angelisation is the most plausible option available to Luke and his earliest readers. Finally, this article demonstrates how an angelomorphic interpretation of Acts 12.15c is congruent with both the broader concern for angelomorphy/angelisation throughout Luke-Acts, as well as the use of humour and irony in Acts 12.12–15.1
Writing in the first century ce, Columella delineates farming practice based on personal experience and observation. Roman attitudes towards slavery, truth, and torture are highlighted in a particularly graphic description of preparing the soil for sowing.
The Charles Keck reliefs on the Nelson-Atkins Museum of Art in Kansas City, MO, portray the triumph of white settlers over Native Americans, who are depicted as stereotypically aggressive and ‘barbaric’. Keck's sculptures invite comparison to the metopes of the Parthenon, which depict the triumph of Greek and Athenian ‘civilization’ over ‘barbarism’. The central focus of Keck's reliefs is Fortitude, an allegorical figure whose image throughout art history is indebted to depictions of Athena and Minerva, and who serves for the Nelson-Atkins as a modern American proxy for the Athenian goddess. As the Periclean building programme proclaimed Athenian superiority and had long-term cultural and economic impacts for Athens, the Nelson-Atkins is intimately connected to the economic and urban development of Kansas City, including its history of racist real estate practices, engineered by a founding trustee of the museum, which became a national model.
Lozano-Duran et al. (J. Fluid Mech., vol. 914, 2021, p. A8) have recently identified the ability of streamwise-averaged turbulent streak fields ${\mathcal {U}}(y,z,t)\hat {\boldsymbol {x}}$ in minimal channels to produce short-term transient growth as the key linear mechanism needed to sustain turbulence at $Re_{\tau }=180$. Here, in an attempt to extend this result to larger domains and higher $Re_{\tau }$, we model this streak transient growth as a two-stage linear process by first selecting the dominant streak structure expected to emerge over the eddy turnover time on the turbulent mean profile $U(y)\hat {\boldsymbol {x}}$, and then examining the secondary growth on this (frozen) streak field ${\mathcal {U}}(y,z)\hat {\boldsymbol {x}}$. Choosing the mean streak amplitude and eddy turnover time consistent with simulations captures the growth thresholds found by Lozano-Duran et al. (2021) for sustained turbulence. In a larger domain at $Re_{\tau }=180$, the most energetic near-wall streaks observed in simulations are close to the predicted optimal streaks. This most energetic streak spacing, approaches the optimal streak at $Re_{\tau }=550$ where the secondary growth possible on each also comes together. A key prediction from the model is that the threshold transient growth required to sustain turbulence decreases with increasing $Re_{\tau }$. More fundamentally, the work of Lozano-Duran et al. (2021) and our results suggest a subtle but significant revision of Malkus's (J. Fluid Mech., vol. 1, 1956, pp. 521–539) classic hypothesis concerning realisable turbulent mean profiles. The key property for a realisable turbulent mean profile could be the ability to generate sufficient short-term transient growth rather than dependence on its (long-term) linear stability characteristics, which was Malkus's original idea.
