This practical report refers to the farm's own data (weight development, sow behavior and lactation) from 2 farrowing passages (DG) in a free-range forest enclosure (DG 1 Feb. 2025: 5 sows; DG 2 May 2025: 3 sows). An additional trial passage (5 sows) in the summer of 2024 was included for the production data. The sows, which were artificially inseminated with Pietrain semen (crossbred sows: Schwäbisch-Hällisch*Pietrain), had 5 farrowing pens with heated piglet nests available for birth in a barn; a feeding area in the barn, the planned space with drinking troughs and a piglet free-range forest enclosure with 620 m² were accessible to sows and piglets at the latest from the 11th day of life (LT) of the first litter of each DG. A few weeks later, the pasture (3,000 m²) and main free-range forest enclosure (16,000 m²) were also opened. Feeding took place with organic concentrate feed components with 11.22 MJ ME/kg, 12.8% crude protein content and large quantities of acre-grass (supplied or grazing). The piglets were not weaned and remained with the sows until natural weaning.On average (trial passage, DG 1 and DG 2), 82.3% of liveborn piglets reached a weight of approx. 25 kg. Losses by crushing were 12.3% (mainly on the first day after birth) and other losses were 5.4%. The average daily weight gain of piglets in DG 1 and DG 2 was between LT 29 (8.01 kg live weight) and LT 78 (29.18 kg live weight) at 432 grams; at the end of week 10, an average group weight of 25 kg was reached. The sows behaved mostly relaxed and neutral towards the farm staff, with a few animals being nervous occasionally. No sow showed aggressive behavior. Recognizable weaning took place from the 13th/14th week of life (LW), with the largest part of weaning completed by the 16th/17th LW.For the presented practical farm keeping sows with piglets in a free-range forest enclosure is an effective way of production. The husbandry system shows adequate daily weight gains, and the sows' distinct feed conversion capability during the natural lactation period means that they can be fed 100% organic feed without any problems. With regard to losses by crushing on the first day of life, management must be further optimized in terms of selection of sows and factors such as bedding.

Habitat Network for the Large Scabious Mining Bee (Andrena hattorfiana): Development of tall oat-grass meadows in the Terminal Moraine Area of the former Inn Glacier // The project "Habitat Network for the Large Scabious Mining Bee" in the northern district of Rosenheim promotes the development of species-rich tall oat-grass meadows (Salvia-Arrhenatherum) on nutrient-poor steep slopes to support the rare Large Scabious Mining Bee (Andrena hattorfiana). The primary threat to these specialized habitats arises from land abandonment or insufficient land use. By analyzing a digital terrain model, potential habitat areas were identified, and land availability was subsequently assessed. Within the scope of the project, the establishment of a functional habitat network comprising 68 individual sites (totaling 39.5 hectares) was achieved through the facilitation of agri-environmental schemes and targeted management measures. Land availability and stakeholder acceptance were exceptionally high (74 %); however, the project was constrained by reduced funding and a shortage of landscape management personnel. This project represents a significant contribution to the local habitat connectivity and aligns with both national and European conservation objectives for the maintenance and restoration of lowland hay meadows (Habitat Type 6510 under the EU Habitats Directive).

Abstract Enbridge aims to assess the transport of hydrogen blends through an existing gas distribution network. Demonstrating suitability of existing pipelines for hydrogen repurposing is a complex task, with limited industry consensus or historic empirical data on hydrogen pipelines adding uncertainty to the process. The 2023 edition of CSA Z662 [1] has provided some clarity through the Engineering Assessment approach introduced for hydrogen repurposing; however, it leaves aspects of the assessment to be further defined. Whilst more prescriptive requirements may be referred to in other standards, such as ASME B31.12 [2], these requirements are liable to change with regular updates and industry research on hydrogen. The subject pipeline network poses particular challenges for Engineering Assessment due to assets being unpiggable, limited availability of integrity data, and the wide range of pipe populations, with construction spanning multiple decades. In the absence of specific data, inspection and testing are essential to reduce the conservatisms and refine risk assessments. Recognizing the challenges in collecting data for an unpiggable and urban distribution system, it is critical to optimize the strategy for testing and inspection. This paper details a project completed between Enbridge and ROSEN to explore the effects of hydrogen on the integrity of the pipeline system in the face of limited data, with an approach centred around an extensive sensitivity study assessing fracture and fatigue. The approach also used an asset ranking model drawing on the findings of the sensitivity study to support effective targeting of inspection and testing to maximize the value from gathered data. In addition to the project findings, this paper provides insights on the implications for hydrogen repurposing of distribution pipelines and systems with limited specific data to support detailed Engineering Assessments.

ABSTRACT Borna disease virus 1 (BoDV-1) was just recently shown to cause predominantly fatal encephalitis in humans. Despite its rarity, bornavirus encephalitis (BVE) can be considered a model disease for encephalitic infections caused by neurotropic viruses and understanding its pathomechanism is of utmost relevance. Aim of this study was to compare the extent and distribution pattern of cerebral inflammation with the clinical course of disease, and individual therapeutic procedures. For this, autoptic brain material from seven patients with fatal BVE was included in this study. Tissue was stained immunohistochemically for pan-lymphocytic marker CD45, the nucleoprotein of BoDV-1, as well as glial marker GFAP and microglial marker Iba1. Sections were digitalized and counted for CD45-positive and BoDV-1-positive cells. For GFAP and Iba1, a semiquantitative score was determined. Furthermore, detailed information about the individual clinical course and therapy were retrieved and summarized in a standardized way. Analysis of the distribution of lymphocytes shows interindividual patterns. In contrast, when looking at the BoDV-1-positive glial cells and neurons, a massive viral involvement in the brain stem was noticeable. Three of the seven patients received early high-dose steroids, which led to a significantly lower lymphocytic infiltration of the central nervous tissue and a longer survival compared to the patients who were treated with steroids later in the course of disease. This study highlights the potential importance of early high-dose immunosuppressive therapy in BVE. Our findings hint at a promising treatment option which should be corroborated in future observational or prospective therapy studies.
