Evaluation of the response of some lettuce cultivars to growth, production and quality indicators using hydroponic systems
(2023-12-28)
The research was conducted at Abi Jarsh Farm in the Faculty of Agricultural Engineering at Damascus University during the first season of 2020-2021 and the second season (experimental repetition) of 2021-2022. The experiment aimed to study the evaluation of growth, production, and quality indicators for two lettuce varieties, Romaine and Iceberg, within various hydroponic techniques: Nutrient Film Technique (NFT), Drip System Technique (DST), Deep Water Culture (DWC), and using three different concentrations of ...

The effect of wuluh starfruit (Averrhoa bilimbi L.) added on the physicochemical and antimicrobial characteristics of chitosan-pva edible film
(2023-12-28)
Edible film is an eco-friendly packaging innovation that can be a solution in dealing with the plastic waste problem. Apart from that, edible film is expected to have antimicrobial properties that can extend packaged food products' shelf life. Wuluh starfruit (Averrhoa bilimbi L.), a tropical plant from Southeast Asia that contains organic acid compounds, functions as an antimicrobial that can be added to edible films. This research aims to determine the effect od wuluh starfruit juice addition in making edible film ...

Preferences of market gardeners for traditional vegetables and associated factors in urban areas of southern Benin
(2023-12-28)
There is a growing interest in the promotion of the use of traditional vegetables to reduce vitamins, minerals, and dietary fibres’ gaps of populations and to support rural and urban livelihoods in sub–Saharan Africa, including in Benin, because they are considered as more nutritious, accessible, and more culturally acceptable for consumers than many exotic vegetables. Meanwhile, the extent to which these traditional vegetables are preferred by the target populations, and especially by the local market gardeners who ...

A Unifying Theory for Runge-Kutta-like Time Integrators: Convergence and Stability
(2024)
The work deals with two major topics concerning the numerical analysis of Runge-Kutta-like (RK-like) methods, namely their stability and order of convergence. RK-like methods differ from additive RK methods in that their coefficients are allowed to depend on the solution and the step size. As a result of this, we also refer to them as non-standard additive RK (NSARK) methods. We motivate and introduce modified Patankar (MP) schemes as a subclass of NSARK methods and emphasize their importance. The first major part ...

Immobilization of Neodymium Complexes on Semiconductor Surfaces and Processing of GaAs-based Photonic Crystals
(2024)
Lanthanide ion luminescence exhibits characteristic narrow emission bands ranging from VIS to NIR along with relatively long emission lifetimes which makes them attractive for applications in lighting, sensing, and display technologies. The focus of this dissertation lies on the optical characterization of newly synthesized neodymium complexes bearing phosphonate ester ligands and the fabrication of photonic crystal (PhC) cavities. Micro-photoluminescence (PL) spectroscopy is used to investigate the NIR emission bands ...

The potential of mangrove as a food source in Riau
(2023-12-28)
Mangrove fruit has been utilized as a food by people in several regions in Indonesia, especially as traditional food. Information about the potential and benefits of mangrove fruit is still limited. There is not much information regarding physico-chemical properties of mangrove fruit as a potential food source. This study aims to gather and review various scientific information related to the potential of mangrove fruit and its use as foodstuff. This information can be used as a basis to conduct further research ...

Prozessintegration von induktiver Wärmebehandlung und Festwalzen – sichere und zuverlässige Komponenten mit hoher Schwingfestigkeit
(2017-02-08)
Mechanische Oberflächenbehandlungen, beispielsweise das Festwalzen, spielen in der technischen Praxis eine bedeutende Rolle und tragen wesentlich zur Steigerung der Zuverlässigkeit hochbeanspruchter Komponenten bei. In einer Reihe von Fällen wurde gezeigt, dass eine Erhöhung der Prozesstemperatur die Wirksamkeit der Verfahren noch steigert, weil dies zu einer besseren Stabilisierung der eingebrachten Druckeigenspannungen führt. Eine wesentliche Voraussetzung zur Einführung dieser Verfahren in die Praxis ist allerdings, ...
