Analysis of near-substrate magnetic particle transport for Lab-on-a-chip applications: stray field modulations, influence of particle properties and three-dimensional trajectories
(2022)
Die Entwicklung schneller und zuverlässiger Diagnostik ist ein wichtiges Ziel für die Früherkennung von Krankheiten. Standardisierte Labormethoden sind heutzutage meist langsam und mit hohen Kosten verbunden. Innerhalb der Lab-on-a-chip (LOC)-Technologie kann der Nachweis eines pathogenen Organismus auf die Größe eines kleinen Chips miniaturisiert werden, indem magnetische Partikel als Fängerobjekte integriert werden. Die Kombination einer statischen Magnetfeldlandschaft (MFL) mit zeitlich variierenden externen ...

Consistency and Computation
(2022)
The diagonal arguments by Cantor, Gödel and Turing constitute fundamental results that demonstrate limits to what is mathematically possible. These results can easily appear to us as limits that must hold, as if they were laws of nature that govern the ideal world of platonic numbers and logic, giving them an “ultraphysical” appearance of rigidity and hardness.
In all three cases, Wittgenstein critically examines the formal ideal of consistency and points out that the conclusions of the diagonal arguments only seem ...

Farmers’ attitudes and perceptions of adoption of agricultural innovations in Kenya: a mixed methods analysis
(2022-08-20)
Attitudes and perceptions are key constructs in decision making. Their nature and influence on agricultural technology adoption among smallholder farmers in Kenya has not been adequately researched. The research applied a mixed methods approach to assess the influence of attitudes and perceptions in adoption of agricultural innovations by smallholder farmers in Kenya. The quantitative phase used a survey (n=245) while the qualitative consisted of focus groups (n=28) to elicit subjective farmer views of innovations. ...

Technical and Environmental Assessment of Energy and Material Production from Rural and Urban Residual Biomass
(2020-04)
Die vorliegende Arbeit umfasst Studien zur Untersuchung technischer und ökologischer Aspekte bei der Nutzung von Restbiomassen in den Nutzungspfaden Energieerzeugung und Aktivkohleproduktion. Im Mittelpunkt der jeweiligen Untersuchung stand das Verfahren zur integrierten Erzeugung von Festbrennstoff und Biogas aus Biomasse (IFBB) und dessen Einfluss auf technische und ökologische Aspekte bei der Verwertung von Restbiomassen. Im Zuge von Naturschutz- und Landschaftspflegemaßnahmen auf extensiv bewirtschafteten ...

Horsegram [Macrotyloma uniflorum]: an underutilized pulse crop as a sustainable plant-based protein
(2022-07-31)
The demand of consumers for plant-based protein is high and is anticipated to increase in the future due to various underlying health benefits. Moreover, the production of high-quality animal protein globally results in a challenging situation for the sustainability of the environment. Contemporary, to find new alternative protein sources, underutilized legumes are given more attention to meet the ever-increasing requirement for vegetable protein.One of the indigenous underutilized legumes is Horsegram (Macrotyloma ...

Development of digital fluorescence light sheet microscopy for high-resolution optical imaging
(2021-12-15)
In modern biology investigating the morphological development of an organism is an inevitable task. Optical microscopy has been extensively used to monitor the live tissue changes in a model organism and it is typically used in conjunction with white light or fluorescence microscopy. The fluorescence microscopy occupies a significant place in biological research due to its ability to address various biological question at subcellular level of a biological sample. One of the more recent developments in fluorescence ...

Simulative Research on a Modified VSM Control Scheme for Respecting DC-Side Active-Power Limitations
(2022)
This thesis presents and examines a novel approach to modify the active-power behaviour of a generic virtual synchronous machine (VSM) in order to respect DC-side active-power limitations of converter-coupled generation and loads, thereby enabling them to participate in instantaneous reserve without hardware reinforcements.
A modification to the VSM control is suggested, which consists of a ∆P feedback loop and a dynamic adaptation of the virtual impedance Xvirt. These mechanisms enable the VSM to have a RoCoF-dependent ...

Sustainability Assessment for Asparagus Farms that Work with a Community-Supported Agriculture Model in Turkey
(2022-07-31)
Due to the diversified nature of agricultural systems, it is difficult to handle the sustainability aspects of different farming practices. With an intention to evaluate the sustainability of the community-supported agriculture (CSA) model in Turkey, the current study focuses on asparagus farms and designs farm-specific sustainability indicators that would be helpful for the farmers. The framework developed for this purpose consists of 20 environmental, 8 economic, and 17 social sustainability indicators derived and ...
