Investigating the efficacy of common agricultural practices for the management of fall armyworm (Spodoptera frugiperda (J.E. Smith)) on cereal crops
(2023-07)
In Benin, the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is the most important polyphagous noctuid pest. This study aimed to assess the impact of agricultural practices on the abundance of this pest and determine whether its feeding preference and larval development differ among four cereal types. First, we conducted a descriptive survey of 80 farmers randomly selected for farm visits and oral interviews using a structured questionnaire to ascertain their preferred agricultural practices ...

„Jetzt kommt da so ne fremde Frau.“ Eine qualitative Analyse zur Beziehungsgestaltung in der ehrenamtlichen Betreuung von Menschen mit Demenz
(2023-06)
Angesichts der steigenden Demenzprävalenz gilt die Sicherstellung einer angemessenen Versorgung von Menschen mit Demenz als besondere Herausforderung unserer Zeit. Um die häusliche Sorge zu stärken und pflegende Angehörig zu entlasten, bietet die Pflegeversicherung Betreuungsleistungen als niedrigschwellige Unterstützung an. Nach § 45a SGB XI können Ehrenamtliche diese Leistung erbringen und Menschen mit Demenz stundenweise betreuen.
Die Dissertation stellt die bislang kaum erforschte soziale Beziehung zwischen den ...

Market-driven harvesting of non-timber forest products and the governance of communal forests in the south-east lowveld of Zimbabwe.
(2023-07)
Despite forests providing a wide range of important products and services for much of Zimbabwe’s population, natural forests are threatened by deforestation. The highest rates of deforestation occur in communal forests. Communal forest resources in Zimbabwe show evidence of increased degradation and signs of a breakdown of local institutions for resources management. These signs of a breakdown of local institutions are coupled with evidence of a lack of any emerging alternative institutions for conservation of forest ...

Hotspot 17 der biologischen Vielfalt - Konzeption zur Förderung der biologischen Vielfalt in der Region „Werratal mit Hohem Meißner und Kaufunger Wald“
(2023)
Im Rahmen des Projektes „Schaf schafft Landschaft“ wurde von Oktober 2019 bis April 2022 eine Konzeption zur Förderung der biologischen Vielfalt in der Region „Werratal mit Hohem Meißner und Kaufunger Wald“ (Hotspot 17) erarbeitet. Bei dieser Hotspotkonzeption wurde ein überregionaler, umsetzungsorientierter Ansatz verfolgt und die gesamte Region des Hotspot 17 in den Blick genommen, um möglichst umfassend die Themen mit besonderer naturschutzfachlicher Relevanz für den Erhalt der Biodiversität zu erkennen und mit ...

Situative Teams in Cooperative Autonomous Systems
(2023)
Distributed systems have been established in many areas of IT and will play an even more significant role in the future. Such systems are no longer limited to specific fields of application but interconnect many different domains. They encompass, e. g. Cloud Computing, Internet of Things, service robotics, and autonomous vehicles. The integrated sub-systems communicate in order to exchange information and, if necessary, perform tasks together. Moreover, the number of interconnected sub-systems is constantly growing. ...

The Computing Boom in the U.S. Aeronautical Industry, 1945–1965
(2023-05-15)
Whereas standard accounts on the history of modern computing tell the development of the digital computer as an isolated event on the East Coast of the U.S., this paper will show the history of machine computing in the context of the broad and rapid development of aeronautical weapons in the U.S. military since 1945. Analogue computing plays an important role that is nearly completely ignored by standard accounts. The extensive literature on the history of electronic digital computers does not take into account the ...

Control of Open Quantum Systems: Examples & Methods for Non-Markovian Dynamics
(2023)
Usually open quantum systems are considered to be under the influence of noise and therefore faulty. On the other hand, a controlled system is regarded as something stable and predictable. It is often neglected, that the two aspects are very closely related. A perfectly isolated quantum system will not be subject to environmental influences, but this makes it also impossible to interact with it in any manner. Controlling and measuring such a system is impossible and therefore of no technical relevance. Every system ...

Numerical simulation of a sub-wavelength plasmonic THz antenna for bio-sensing applications
(2023)
In the past decades, bio-sensing has become a steadily growing field in the life-sciences. Popular subjects of investigation are proteins, which for instance mediate intra-cellular transfer of substances and thus are attractive drug targets. They are also responsible for the occurence of degenerative diseases such as Alzheimer’s disease and the Creutzfeld-Jakob disease. Examining proteins to uncover their fundamental properties and behavior is important in order to advance modern health care and medicine. One way to ...

Gold Mining (artisanal gold mining): Is it an engine of development in Mauritania?
(2023)
• In 2021, Mauritania exported approximately 13 million tons of iron, 20% of which was bound for Western Europe.
• The economic structure of this country is increasingly rent based.
• The extractive sector does not act as a catalyst for the country's development. Its contribution to poverty reduc-tion remains insignificant.
• Poverty remains a significant feature of the country, ranking 157th out of 189 according to the Human Development Index in 2020.
