Background: Struvite, biochar and ash products (collectively known as STRUBIAS) derived from different waste streams are used as fertilisers in agriculture. Raw dairy processing sludge (DPS) shows promise as bio‐based fertilisers, but secondary STRUBIAS‐derived products need further testing as fertilisers. Aims: The objective of this study was to calculate the phosphorus mineral fertiliser equivalency (P‐MFE) for some STRUBIAS products derived from DPS. Methods: Ryegrass (Lolium perenne L.) and wheat (Triticum aestivum) pot trials were used to determine the P‐MFE using the apparent P recovery (APR) method for Fe‐DPS and DPS‐derived struvites (Struvite 1–4), hydrochars (HC1–3) and ash. Results: The tested STRUBIAS products can be divided into two groups: (1) a range of products that can (i.e. Struvite 1–3) and (2) cannot (i.e., Struvite 4, HC1–3, ash and Fe‐DPS) be considered fertilisers. In the first group, the P‐MFE ranged from 66.8% to 76.7% for ryegrass and from 77.9% to 93.5% for spring wheat grain. In the second group, the P‐MFE ranged from 7.8% to 58.3% for ryegrass and from −34.5% to −151.3% for spring wheat grain. The negative agronomic effects of some products for wheat grain (struvite and HC) in this study were mainly caused by high Fe content, which could be overcome by improved treatment processes. Conclusions: Future policy and research must be aware that not all the DPS‐derived STRUBIAS products are suitable as fertilisers and therefore need to be tested individually. [ABSTRACT FROM AUTHOR]

Adequate vitamin D status may be important in preserving muscle function. We aimed to determine the association between impaired muscle function and serum vitamin D status in community-dwelling older adults. Falls were explored as a secondary aim.Methods: Data were analyzed from adults aged ≥60 years, from Wave 6 of the English Longitudinal Study of Aging (ELSA). Handgrip strength (HGS) and the short physical performance battery (SPPB) were employed as measures of muscle strength and physical function, respectively. Serum 25-hydroxyvitamin D [25(OH)D] was assessed with concentration

Few studies have examined exercise placement within children-specific programming. This study aimed to investigate the frequency and type of exercise placement in children-specific television broadcasts and to compare placements on the UK and Irish television channels.Methods: Content analysis for five weekdays’ worth of children-specific television broadcasting totaling 82.5 hours on both the UK (British Broadcasting Corporation) and Irish (Radió Teilifís Éireann) television channels was performed. For the purposes of comparing the UK and Irish placements, analysis was restricted to programming broadcast between 6 am and 11.30 am. Exercise placements were coded based on type of activity, activity context, activity motivating factors and outcome, and characters involved.Results: A total of 780 cues were recorded during the total recording period. A wide variety of sports were depicted, but dancing-related cues were most commonly seen (n=163, 23.3%), with the majority of cues being of mild (n=365, 65.9%) or moderate (n=172, 31.0%) intensity. The majority of cues were associated with a positive outcome (n=404, 61.4%), and social motivations were most commonly seen (n=289, 30.3%). The Irish and the UK portrayals were broadly similar.Conclusion: This study highlights the wide variety of sports portrayed and the active effort undertaken by television stations to depict physical exercise and recreation in a positive light.
