Sustainable livestock systems in Ethiopia: Assessment of the status quo and options for improvement with a focus on animal welfare, market systems, gender roles and human-wildlife conflict management
Full text linkThis study brings together three strands of research to provide a holistic understanding of animal welfare challenges and opportunities in Ethiopia, focusing on farmers' willingness to engage in welfare initiatives, market-level welfare conditions, and traditional methods for managing human-wildlife conflict. Together, these findings offer critical insights for policy and program development aimed at improving both animal well-being and rural livelihoods.
The first chapter explores farmers’ preferences and willingness to participate in voluntary animal welfare schemes using mixed logit models in preference and willingness to pay space to assess the relative importance of different attributes of animal welfare schemes on farm households’ participation. Results show that financial incentives are the most significant factor influencing participation. Farmers indicated a need for compensation equivalent to 11% of their annual livestock sales to participate in welfare programs. More demanding welfare improvements such as optimal welfare standards or improved training required significantly higher compensation, up to 25–26% of livestock sales per year. These findings underline the importance of aligning welfare improvements with tangible economic benefits to ensure farmer engagement. Policy recommendations include the development of flexible, farmer-oriented schemes that combine financial incentives with accessible training and community-based approaches.
The second chapter assesses the state of animal welfare in three livestock markets: Addis Ababa (terminal), Adama (secondary), and Meki (local). The analysis reveals substantial variation in infrastructure and animal handling practices. While the terminal market offers relatively humane conditions and access to basic amenities such as water and shelter, the local and secondary markets lack such facilities and are characterized by poor handling practices, including forceful movement and lack of rest. These conditions contribute to animal stress and injury, undermining both welfare and market efficiency. Additionally, the study highlights gender inequalities in market participation, with women facing systemic barriers. To address these challenges, the study recommends investment in welfare-supportive infrastructure, implementation of enforceable national welfare standards, comprehensive training for handlers, and policies that actively promote gender inclusion.
The third chapter focuses on human-wildlife conflict around Nech Sar National Park, analyzing the economic and social impact of livestock predation and crop damage. Households within 16 kilometers of the park suffer average annual losses of $76.78, which is approximately 77% of their annual income, due to wildlife incursions. While traditional guarding practices are widely used, most respondents viewed them as ineffective unless rigorously applied. Gender differences were also evident: male-headed households experienced greater cattle losses, while female-headed households were more affected by poultry predation which reflects differences between genders in species kept. The findings emphasize the need for a combination of modern and traditional strategies, including expanded buffer zones, improved fencing, gender-sensitive planning, and community engagement to reduce conflict and protect livelihoods.
Taken together, these three studies provide a comprehensive picture of the multifaceted issues affecting animal welfare and rural livelihoods in Ethiopia. They underscore the importance of integrating financial incentives, infrastructure investment, gender equity, and local knowledge into national policy. By addressing the economic factors of farmers, improving market conditions, and supporting community-based conservation, Ethiopia can move toward more sustainable and inclusive animal welfare systems
On the 21 Card Trick and Verini's Lost Trick
Full text linkWe provide a necessary and sufficient condition for the solvability of generalized variants of the twenty-one card trick (21CT). The 21CT works by dealing the cards into three stacks several times and, after the spectator identifies the stack containing their card each round, arranging the stacks so the performer always knows where the chosen card ends up for the final reveal. Our analysis extends to any number of cards, arranged in multiple stacks, with an arbitrary number of cards per stack and an arbitrary number of iterations of dealing into stacks. We also allow for flexible collection of the stacks induced by face-down or face-up dealing of the deck of cards, ensuring that the unknown card appears at a predetermined position within the deck. Notably, this also allows us to analyze the historically first card trick to appear in print, proposed by Verini in 1542---a lost card trick that was rediscovered only recently: it turns out that the trick does not work. But, we also demonstrate how it can be fixed

Reconstruction of the Sigma0 baryon in Ag+Ag collisions at sqrt(s_NN) =2.55 GeV with HADES
No full textThis work presents the experimental reconstruction of the Sigma0 baryon in – with respect to NN interactions – subthreshold Ag+Ag collisions at 1.58 AGeV kinetic beam energy measured with the HADES experiment.
At the HADES experiment, which is located at GSI in Darmstadt, Germany, heavy ion collisions at moderate freeze-out temperatures and high baryon chemical potential are measured, analyzed, and evaluated in comparison with the existing data as well as theoretical predictions. This kinetic beam energy corresponds to a center of mass energy of sqrt(s_NN) = 2.55 GeV, which is the Lambda baryon production threshold in NN collisions. With only a small mass difference of Sigma0 to the Lambda baryon of 77 MeV/c^2, Sigma and Lambda baryons are the lightest strangeness containing baryons. Since all quantum numbers of the Sigma0 and the Lambda baryon are identical, their production mechanisms are expected to be very similar. Due to a different spin configuration of the valence quarks inside the Sigma0 , the Sigma0 is slightly more heavy and decays with nearly 100 % branching ratio into Lambda-photon. However, the reconstruction of the low-energy photon is challenging for most detectors, particularly when attempting to concurrently satisfy the requirements of Lambda reconstruction.
For the beamtime of the analyzed Ag+Ag collisions, 15 billion events were recorded. The newly installed electromagnetic calorimeter enables photon reconstruction for HADES for the first time without relying on the previously used conversion method. Within the 0-40 % most central events, around 8000 Sigma0 baryons were reconstructed in the Lambda-photon channel with a significance of approximately 10. In addition to the newly installed electromagnetic calorimeter, the RICH was upgraded with newmulti-anode photomultipliers which strongly enhance reconstruction efficiency as well as lepton purity. These advantages were used for feasibility studies in the Lambda-e+e− decay channel. Hints for a signal were found that are consistent with the extracted signal from the Lambda-photon channel, but due to the small statistics, only a significance level of less than 3 was achieved.
A full efficiency and acceptance correction was performed with a resulting multiplicity of 0.014 ± 0.002stat. ± 0.004sys. produced Sigma0 per event which corresponds to a Lambda/Sigma0 ratio at freeze-out of 3.2 ± 0.3stat. ± 0.6sys.. This represents the first measurement of this ratio for a subthreshold Sigma0 production in nucleus nucleus collisions.
Comparing to the available world data of p+p collisions close to the Sigma0 production threshold, this ratio increases in p+p to values of 30 and higher. Even more, the measured ratio compares well to measurements in p+p far from threshold. This indicates that the NN threshold has no influence on the Sigma0 production for this energy. The Lambda-photon channel result is compared to statistical hadronization model fit as well as to several transport model predictions. The statistical model calculations are in good agreement to our measurement which endorses the possibility of hyperon production in a thermally equilibrated medium. In this case, the freezeout ratio is directly connected to the mass difference of two states with the same quantum numbers, resulting in a temperature estimation of the created matter by only measuring Lambda and Sigma0. From these measurements T=66 MeV is extracted, which compares well with fits of all hadrons with a statistical model
Retrospektive Analyse der Verknöcherung der Transitionszonen nach freiem Fibulatransplantat: Vergleich zweier Osteosyntheseverfahren – konventionell vs. patientenspezifisches Implantat (PSI)
No full textDie vorliegende monozentrische, retrospektive Studie untersucht Patienten, die einer Rekonstruktion des Ober- oder Unterkiefers mittels freien Fibulatransplantats (FFF) aus dem Zeitraum von Januar 2005 bis Dezember 2021 unterzogen wurden. Mithilfe von Orthopantomogramm- (OPG), Computertomografie- (CT) sowie Volumentomografie- (DVT) Aufnahmen erfolgte eine detaillierte Analyse der knöchernen Vereinigung an den intersegmentalen Übergängen zwischen dem nativen Ober- oder Unterkiefer und dem Fibulaknochen. Der zentrale Parameter der Untersuchung war dabei der Status der knöchernen Vereinigung in Abhängigkeit vom Osteosynthesetyp. In die Analyse wurden insgesamt n = 133 Patientenfälle eingeschlossen, wobei die Aufteilung in PSI (64 Patienten) und Non-PSI (69 Patienten) erfolgte. Das mittlere Alter betrug 56,7 ± 14,0 Jahre, wobei die primäre Diagnose bei 78,9% der Fälle ein Malignom und bei 15,0% ein gutartiger Tumor war. Bei 103 Patienten (77,4%) wurde eine Unterkieferrekonstruktion durchgeführt und bei 30 Patienten (22,6%) eine Oberkieferrekonstruktion. Die radiologischen Aufnahmen zeigten eine Rate unvollständiger knöcherner Fusion (IOU) von etwa 90% in beiden Gruppen in den ersten sechs Monaten. Die Bildgebung zwischen 6 und 12 Monaten zeigte eine IOU-Rate in der Non-PSI-Gruppe von 46,3% gegenüber 52,5% in der PSI-Gruppe, während zwischen 12 und 24 Monaten eine IOU-Rate von 19,6 % in der Non-PSI-Gruppe und 26,1 % in der PSI-Gruppe festgestellt wurde. Zwischen 24 und 36 Monaten war die IOU-Rate 8,9 % in der Non-PSI-Gruppe gegenüber 21,7 % in der PSI-Gruppe. Nach 36 Monaten sank die IOU-Rate auf 4,2% gegenüber 18,2%. Die multivariate logistische Regressionsanalyse identifizierte den Osteosynthesetyp (OR = 3,945 [95 %-KI = 1,319 – 11,795], p = 0,014) sowie die adjuvante Radiochemotherapie (OR = 7,737 [95 %-KI = 2,239 – 25,058], p = 0,001) als unabhängige Risikofaktoren für eine unvollständige knöcherne Konsolidierung. Die Cox-Regression zeigte, dass sowohl das verwendete Plattensystem (HR = 5,014; 95 %-KI: 1,826 – 3,769; p = 0,002) als auch die adjuvante Radiochemotherapie (HR = 5,710; 95 %-KI: 2,066 – 15,787; p < 0,001) Prädiktoren für eine unvollständige Ossifikation darstellen. Die Analyse hebt insebesondere die signifikant höhere Rate unvollständiger Ossifikation in der PSI-Gruppe hervor, wobei Übergangszonen Kiefer-Fibula stärker betroffen waren als intersegmentale Zonen. In der multivariaten Analyse wurde eine Kombination aus Osteosynthese mit PSI und adjuvanter Radiochemotherapie als Risikokonstellation für unvollständige Verknöcherung identifiziert
Dynamics and Cultivation of Gut Microbiota in Hermetia illucens Larvae
No full textUnderstanding the interplay between Hermetia illucens larvae and their gut microbiome is essential for harnessing these insects in waste management and animal feed production. This investigation assessed the bacterial communities within the larval gut and the accompanying feed residue throughout the rearing process. The findings indicate that the larval gut maintains a stable core microbiome comprising genera such as Dysgonomonas, Morganella, Enterococcus, Providencia, and Klebsiella, with high strain-level diversity that may underline the larvae’s adaptability to various substrates. In contrast, the feed residue exhibits marked shifts in the bacterial composition during rearing, including a significant reduction in potential pathogenic taxa.
Dynamic changes in antibiotic and disinfectant resistance genes were observed: the methicillin resistance gene (mecA ), initially prevalent in the residue, was reduced over time; the β-lactamase gene (blaSHV) remained consistently present in the larval gut but disappeared from later residue samples; and while quaternary ammonium compound resistance genes (qacE/qacEΔ1) were absent from the gut; their abundance increased in the residue. Additionally, the sulfonamide resistance gene (sul2) showed a significant increase in the residue, whereas tetracycline resistance gene (tetM) levels remained constant across both matrices.
Furthermore, the use of both dilution-to-extinction- and direct plating cultivation methods facilitated the isolation of 18 distinct phylotypes, revealing a high genetic diversity within key genera such as Providencia, Enterococcus, and Morganella. These results underline the complexity of microbial dynamics during H. illucens rearing and highlight potential environmental concerns regarding the dissemination of resistance genes through organic waste.
In summary, the findings elucidate the intricate microbial dynamics present during H. illucens rearing. The resilience and diversity of the larval gut microbiome contrast with the substantial compositional and functional changes observed in the feed residue. Moreover, the documented shifts in antibiotic- and disinfectant resistance gene profiles highlight the potential environmental implications that warrant further investigation. These insights provide a foundation for the rational design of bioconversion processes and the optimization of strategies ensuring an improved microbiological safety of animal feed products
Luminescent and Conductive Hybrid Materials based on Nanoscale Metal-Organic Frameworks and (Bio)Polymers
No full textThis PhD thesis is centred around a unifying theme: the design and fabrication of hybrid materials that integrate nanoscale metal-organic frameworks (nanoMOFs) with (bio)polymers, targeting advancements in materials science and greener chemistry. A multi-faceted research approach has been applied to address this topic, with three main objectives: first, to synthesise nanoscale versions of bulk MOFs known from the literature; second, to develop nanoMOF@polymer hybrid materials with multi-level anti-counterfeiting mechanisms; and third, to synthesise environmentally friendly nanoMOF@biopolymer materials according to green chemistry principles. During the elaboration of the set scientific scope, all key objectives were successfully achieved, leading to notable achievements in the areas studied.
A surfactant-assisted bottom-up synthesis route has successfully produced nanoMOFs with enhanced photophysical and morphological properties compared to their bulk versions. Mixed-matrix-membranes (MMMs) and powders composed of lanthanide-containing nanoMOFs (nLn3+-MOFs) and anthropogenic polymers (APs) have been developed, exhibiting multi-level anti-counterfeiting with interconnected properties, making them highly secure and difficult to replicate, thereby suitable for security-related applications. Aiming towards sustainability, developed nLn3+-MOFs were combined successfully with biopolymers yielding biodegradable and recyclable MMMs, hydrogels and cryogels. These bio-based materials demonstrating high regeneration capacity and stability over multiple recycling steps, align with green chemistry principles.
Dispersibility and particle distribution benefit from the nanocharacter of nLn3+-MOF particles, which is a critical requirement for stable and resilient hybrid materials. The visible (Vis= Eu3+, Tb3+) and invisible (NIR= Yb3+) photoluminescence of developed nLn3+-BDC (BDC2−= benzene-1,4-dicarboxylate), together with the conductivity of the APs polystyrene sulfonate (PSS) and pyrolysed resorcinol-formaldehyde (pRF) were used to create an additive multi-level anti-counterfeiting. Each feature (Vis-light, NIRlight, conductivity) represents a certain level of security, while they are interconnected by optical and physical properties – changing one will inevitably change another of the levels. The materials developed are designed to be difficult to replicate for unambiguous marking of valuable goods. As materials science has to address sustainability to overcome environmentally relevant challenges in the future, APs have been replaced by biodegradable nature-based biopolymers agar and gelatine. Luminescent MMMs made from nEu3+-BDC@biopolymers have been successfully recycled ten-times, while the red luminescence allows for the monitoring of the material’s condition. Resilient nEu3+-BDC in boiling water and freezing temperatures as well as water-based synthesis routes, render these materials suitable alternatives for AP-based hybrid materials.
Altogether: improved synthesis techniques, application-driven approaches and biodegradable alternatives enable the creation of advanced nanoMOF@(bio)polymer hybrid materials supporting anti-counterfeiting, sustainability and circular economy.Deutsche Forschungsgemeinschaft (DFG); ROR-ID:018mejw6
