Potential and risks of water reuse in Brandenburg (Germany) – an interdisciplinary case study
(2024)
For Brandenburg, a region in Germany with increasing water shortage and drought events, water reuse can counteract competition scenarios between drinking water supply, agricultural irrigation, and industrial use. Centralized and decentralized sources for reclaimed water are found to potentially substitute 245 or 28% of irrigation water, respectively, in agriculture production in Brandenburg. For such a reuse scenario, the
fate of organic micropollutants is examined for diatrizoate (DZA) and carbamazepine (CBZ). Retention in local sandy soil and transfer into roots and leaves of arugula are analyzed in lysimeter studies and greenhouse pot experiments. Vertical transport was found for DZA and accumulation in or on arugula roots with a root concentration factor of 1,925+34% but a low bioconcentration factor due to intrinsic molecule properties. CBZ was not found to be mobile in the sandy soil but accumulates in arugula roots and leaves by factors of 70+7% and 155+12%, respectively. Further research on potential plant uptake and groundwater enrichment for more substances is highly recommended as well as tertiary wastewater treatment prior to water reuse.
The preservation of water bodies continuity is fundamental
for aquatic communities, particularly for fish
populations. Various structures impede watercourse
continuity, impacting fish migration and habitat distribution.
Conventional fish passages often fall short
in diverse scenarios, prompting the development of
specialized solutions. This article proposes a criteria
catalog for these special fish passage solutions based
on DWA leaflet DWA-A 509. It discusses the need
for these solutions, presents a selection of specialized
options, and outlines criteria from DWA-M 509, construction
guidelines, and economic perspectives. It
scrutinizes criteria ranging from target fish species to
cost considerations. Three examples, including the
Runserau fish lift, the bristle ramp fish lock, and the
Fishcon sluice, illustrate these specialized solutions,
their functionalities, advantages, and drawbacks. Additionally,
the article compiles criteria from industry
standards and guidelines into a comprehensive evaluation
catalog. The criteria, when applied, assist in the
selection of suitable fish passage solutions based on
specific site conditions and fish species requirements.
This holistic approach aims to optimize fishway selection,
fostering the ecological sustainability of watercourses.
However, this catalog remains dynamic
and open to expansion with evolving research and
practical application, urging further exploration and
validation of these criteria through diverse case studies
and technological advancements in the field.
The urge for personalisation and the rise of technological advancements
in the 21st century is pushing for more innovative marketing strategies. As such, this dissertation examines the impact of personality-tailored
campaigns (PTC) and how it affects purchasing decisions among
Generation Z, focusing on theoretical and practical implications.
A conceptual framework for the process of personality-tailored marketing has been developed to provide tangible value for businesses of
various industries in particular the fragrance, smartphone, and food
industry.
Die Integration von Künstlicher Intelligenz (KI) im Gesundheitswesen ist zu einem Schwerpunktthema geworden und dominiert aktuell Diskussionen in Kliniken allgemein als auch Pathologien spezifisch. Trotz des Enthusiasmus klafft nach wie vor eine Lücke zwischen den Erwartungen der Anwender und den tatsächlichen Vorteilen nach der Implementierung. Dies spiegelt sich in den Herausforderungen der KI-Integration wider.
In der folgenden wissenschaftlichen Studie widmen wir uns den Erwartungen von Akteuren im Gesundheitswesen – spezifisch in Kliniken und Pathologien – an KI-Lösungen und ihren Einsatz. Dabei wird ein besonderer Fokus auf die dahinterliegenden Faktoren gelegt, die die aktuellen Erwartungen und die daraufhin ergriffenen Maßnahmen beeinflussen. Unsere Ergebnisse stützen sich sowohl auf den wissenschaftlichen Diskurs als auch auf die weite, öffentliche Diskussion zur praktischen Umsetzung – wie in Expertenberichten, Interviews, Konferenzbeiträgen und Artikeln aus Politik, Kliniken und weiteren Institutionen.
Dadurch trägt die Studie zu einem besseren Verständnis der aktuellen KI-Erwartungen und ihrer beeinflussenden Faktoren bei und befähigt Akteure in dem Markt, die Zukunft von KI im Gesundheitswesen mitzugestalten.
