Computing Ground States for Fermi-Bose Mixtures through Efficient Numerical Methods
(2023-05)
In this work, we will first review the Quantum Mechanics theory to derive the main equations. Next, we will analyze these equations by Functional Analysis methods to find conditions for existence, uniqueness, multiplicity, and other properties as positivity. Next, we will review and develop some numerical methods for solving the nonlinear Schrödinger equation, its time version, generalizations with rotational terms, and systems of NLSE (NLSS). We notice that the main problem to run numerical methods is the memory ...

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 ...

Thermal Properties of Plasticized Cellulose Acetate and Its β-Relaxation Phenomenon
(2021-04-21)
Cellulose acetate (CA), an organic ester, is a biobased polymer which exhibits good mechanical properties (e.g., high Young’s modulus and tensile strength). In recent decades, there has been significant work done to verify the thermal and thermomechanical behaviors of raw and plasticized cellulose acetate. In this study, the thermomechanical properties of plasticized cellulose acetate—especially its β-relaxation and activation energy—were investigated. The general thermal behavior was analyzed and compared with ...
