Ein Platz an der virtuellen Sonne
(2021)
Diese Arbeit möchte untersuchen, wie die Kolonialzeit im digitalen Spiel „Anno 1800“ verhandelt wird, wie ludischer Imperialismus An-wendung findet und wie mit diesem gebrochen wird sowie welche Geschichtskulturen dadurch gestiftet werden.
Um dem zuvor formulierten Forschungsinteresse nachzugehen, kann die Arbeit auf geschichtswissenschaftliche Forschung zurückgreifen. Sie untersucht, wie sich die spezifischen Besonderheiten des Mediums auf dessen Konstruktion und Verhandlung von Geschichte auswirken. Daher kommt ...

Identifying critical demand scenarios for the robust capacitated network design problem using principal component analysis
(2021-11-30)
In this paper, we consider the single-commodity robust network design problem. Given an undirected graph with capacity installation costs on its edges and a set S of scenarios with associated flow balance vectors that represent different scenarios of node supplies and demands, the goal is to find integer edge capacities that minimize the total installation cost and permit a feasible single commodity flow for each scenario. This problem arises, for example, in the design of power networks, which are dimensioned to ...

A Self-Organising Multi-Agent Knowledge Base
(2021-12)
Digitale Städte sind zunehmend auf IT- und Kommunikationsinfrastruktur angewiesen. Sie können als große verteilte Systeme betrachtet werden, die aus heterogenen und autonomen Teilnehmern bestehen. Besonders in Notfall- und Krisensituationen muss kritisches Wissen, beispielsweise über verletzte Personen oder beschädigte Infrastruktur, zuverlässig auch unter eingeschränkter Kommunikation erreichbar sein. In einer solchen Umgebung würde eine zentrale Verwaltung des kritischen Wissens einen Engpass verursachen. Daher ...

Influencing factors of adopting solar irrigation technology and its impact on farmers’ livelihood. A case study in Bangladesh
(2021-12-15)
Sustainable irrigation access is considered critical for agricultural growth in Bangladesh, which vindicates the food and livelihood security. Solar powered irrigation system had emerged as promising technology to make sustainable irrigation in Bangladesh. This study examines the factors affecting the adoption of solar powered irrigation system and the impact of this technology on livelihood of farmer. To conduct this analysis, data were collected from Meherpur district of Bangladesh. Simple random sampling technique ...

Food rescue and donation in socioenvironmental policies on tackling food loss and waste: a systematic review
(2021-12-20)
In recent years, there has been an increasing concern among governments about food loss and waste – FL&W and, in this context, the food rescue and donation – FR&D has emerged in the scenario of socioenvironmental policies as a strategic factor for FL&W reduction. Despite FR&D have potential to establish a “win-win” arrangement between the spheres of waste management and demands of food security, it still has been perceived as a less attractive alternative than forwarding the surplus food to the waste treatment system. ...

Decontamination of Pineapple (Ananas comosus) juice using Ozone as a Non-thermal Sterilization method
(2021-12-15)
Ozone is a non thermal preservation technology used for enhancing shelf life and the safety of the food products. The objective of this study was to evaluate the effect of gaseous ozone on microbial decontamination and on some physicochemical characteristics (soluble solids content, pH, titratable acidity and color), bioactive compounds and total antioxidant activity of Pineapple juice. Ozone treatments were applied for Pineapple juice at 4 different exposure times as 15 mins, 30 mins, 45 mins and 60 mins at 250C and ...

Three-dimensional hydrodynamic and ecosystem modeling of warm-monomictic reservoirs (Maroon and Abolabbas, Iran) under the impact of 21st century climate change
(2021-11)
Lakes and reservoirs, as the endpoint of their upstream catchment, collect their water as the resultant of the hydrological and ecosystem processes and, thus, act as a gauge of their catchment’s management. Physical processes, e.g. stratification and mixing and propagation of density currents, are the main drivers of the biochemical factors in lakes and reservoirs and are prone to be altered and affected by climate change. Hydrodynamic models are the tools to simulate the behavior of the water body under various ...

Las tradiciones discursivas
(Walter de Gruyter, 2021-01-18)
La tradición discursiva como molde cultural para la configuración de discursos y textos es un concepto clave de la lingüística del hablar. Este concepto, derivado del modelo de las reglas y tradiciones del hablar de Coseriu, desempeña además un papel primordial en la lingüística del texto y la pragmalingüística, debido al potencial analítico y la agudeza explicativa que proporciona el modelo coseriano. Es capaz de diferenciar claramente entre la historicidad y la universalidad del hablar y, asimismo, permite identificar ...
