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 ...

Bringing heterodoxy back into a world of pessimism
(2024-01-29)
In this Extractivism Occasional Papers’ volume, we brought together two first-wave scholars working on structuralism, class and development, Luiz Carlos Bresser-Pereira and Hartmut Elsenhans, and upcoming scholars – Ingrid Harvord Kvangraven, Fernando Rugitsky and Johanna Siebert – who build on structuralist thinking to present their own take on the importance of revitalising it. Our project follows the Hegelian dialectics and seeks aufheben, in the sense of learning from the past, preserving what is valuable, and ...

Operaciones de invisibilización. El caso del Portal Único del Estado colombiano (GOV.CO)
(Editorial Biblos, 2023)
La presente contribución tiene como objetivo presentar aproximaciones interdisciplinares a las actividades regulatorias del Estado a la hora de comunicarse con los ciudadanos. Suponemos que tales actividades se asocian a prácticas de invisibilización y simplificación de sus destinatarios que muestran concepciones de la ciudadanía y de la nación fuertemente acotadas que ignoran las realidades de las poblaciones a las que van dirigidas. Para lograr este objetivo, proponemos una lectura multimodal de contenidos seleccionados ...

Searching for a substitute: Algeria and Venezuela as energy security alternatives for Europe?
(2024-01-26)
• Venezuela und Algerien sind für die Europäische Union potenzielle, zukünftige Energiepartner.
• Die EU steht vor einer doppelten Herausforderung: Sie muss kurzfristige Alternativen für Gaslieferungen finden und sich langfristig
einem green deal verpflichten. Dies erfordert einen grundlegenden Wandel der Zusammenarbeit zwischen EU mit ihren
Energielieferländern.
• Algerien verfügt über großes Potenzial erneuerbarer Energien, es mangelt ihnen jedoch an Technologie und Kapital. Eine EUAlgerien
Energiepartnerschäft ...

Les dynamiques socio-économiques du Hirak Algérien : un facteur souvent ignoré
(2023-09)
• In 2019, Algeria experienced one of the largest popular uprisings the country has ever seen in its post-independence history: the Hirak.
• The crisis had been looming for several years, as shifts in the political elite increased. The end of the financial boom exacerbated this process.
• Between 2015 and 2018, oil and gas export revenues declined by an average of 14% per year.
• Socioeconomic factors ultimately contributed to the outbreak of the Algerian hirak.

Twin Basic Quantum Calculus and its Applications
(2024)
We give in this work some results on twin basic quantum calculus. The (p,q)-derivative, the (p,q)-integral and some (p,q)-Taylor formula are discussed. Next, we introduce and provide several results about (p,q)-Gamma and (p,q)-Beta functions. Some (p,q)-Sturm Liouville problems are introduced and some (p,q)-hypergeometric solutions are obtained. The work ends with the introduction (p,q)-Appell polynomials and some (p,q)-Laplace transforms.

Food security status and its determinants: A comparative study between farm households under government and non-government agricultural extension services in Bangladesh
(2024-02-29)
The ability to obtain food security is essential to human existence. Secure food access can have a variety of positive effects, such as economic expansion, the creation of jobs, and the eradication of poverty. This study assessed the food security status of farm households and its determinants in the Dinajpur district of Bangladesh. Efforts were also made to assess and compare the socio-economic demographics and item-wise calorie intake among households receiving government and non-government agricultural extension ...

Development of deep-placement fertiliser applicator and modelling of loads arising in the process of its operation
(2023-12-28)
The article considers the method of minimum tillage, namely soil tillage, loosening the soil, and fertiliser application at a depth below the level of the main crop. This method allows you to minimize the number of operations used in the cultivation of row crops such as soybeans, wheat, and others. The research in the area of soil tillage, namely the mathematical calculation and static analysis performed with the CAD system, revealed the loads that appear directly in the places where the soil deepener is attached to ...

Parameter identification for constitutive models of innovative textile composite materials using digital image correlation
(2019-11-18)
This contribution focuses on an innovative composite material consisting of textile layers made from continuous wooden fibers embedded in a thermoplastic matrix. A finite element simulation of potential use‐cases is planned to support the development process and to study the suitability of the material in an architectural context. The simulation is based on a constitutive model assuming homogenous orthotropic elastic behavior and will be expanded to include multiscale modeling in future research. The material parameters ...
