Agroecological heuristics: Xi (Ξ) biomathematical models of alpha diversity and Lambda functional entropy index (λ) applied for macrofauna in diversified agroecosystems of Nicaragua
(2021-12-08)
Agriculture causes chaos on the macrofauna associated with agroecosystems. The functions developed by macrofauna species in agroecological environments are harmful, beneficial and fundamental for food production. In order to design Xi (Ξ) biomathematical models of alpha diversity and to create a functional entropy index (λ), the taxonomic identification of macrofauna was carried out in 10 agroecosystems with conventional and agroecological production approach in five locations of Nicaragua: Boaco, Carazo, Chinandega, ...

Effects of agroecological practices on soil organic carbon sequestration using synchronic and diachronic approaches in Madagascar
(2020-06-16)
Soil organic carbon (SOC) sequestration in agricultural systems is a key indicator of soil fertility improvement and climate change mitigation at the global scale. In Madagascar, the effect on SOC sequestration of converting from traditional practices to agroecological ones remains unclear. The objectives of this study were (i) to assess the impact of agroecological practices, such as agroforestry (AF), tree plantation (TP) and improved farming practices (IFPs), on SOC sequestration at the field level; and (ii) to ...

Morphology, biochemistry, and management of Russian olive (Elaeagnus angustifolia L.) accessions in Gilgit-Baltistan, northern Pakistan
(2020-07-30)
Russian olive (Elaeagnus angustifolia L., Elagnaceae) is a native multi-purpose medicinal shrub or tree of Asian regions and an integral component of high altitude terraced agroforestry systems of Gilgit-Baltistan, northern Pakistan. The strong increase in deforestation, urbanisation, and the loss of ethnically-based medication practices in local communities are gradually leading to depletion of its stands and knowledge of its use. In view of these circumstances, this study was undertaken to characterise Russian olive ...

Characterization of Mechanical Properties, Macroscopic Deformation Behavior, and Microstructure of Functionally Graded 22MnB5 Steel
(2021-03-24)
The focus of this study is on the characterization of the local plastic deformation and failure of functionally graded 22MnB5 plates after hot stamping using an in situ approach. Various forming strategies at elevated temperatures are performed using differentially tempered forming tools to locally tailor the microstructure. By controlling the cooling rate, graded as well as martensitic and ferritic–pearlitic microstructures are obtained. Experimental analysis includes evaluation of the material- and geometry-dependent ...

Variation in baobab (Adansonia digitata L.) root tuber development and leaf number among different growth conditions for five provenances in Malawi
(2020-08-21)
The baobab tree is an underutilised indigenous fruit tree in sub-Saharan Africa which, at the same time is vulnerable to overexploitation in areas close to centres of demand, as currently baobab use is limited to wild, baobab trees. Baobab seedlings are known to form root tubers, but little is known about their growth characteristics and its yield potential. This study aims to investigate the root tuber and leaf development of baobab seedlings grown from seeds of five provenances, sown at three different planting ...

Application of non-linear models in description of growth of dual purpose FUNAAB Alpha chickens
(2021-08-03)
Growth is explained mathematically by models that have parameters with biological interpretations. This study was conducted to compare five non-linear growth models (Gompertz, Brody, Logistics, Von Bertalanffy and Negative exponential) in order to describe growth in the three genotypes (normal feather, naked neck and frizzle feather) of the dual purpose FUNAAB Alpha chickens (n=332). Doesn’t Use Derivative iterative method of nonlinear procedure in SAS was used to estimate the model parameters. Computational difficultly, ...

[Rezension zu:] Westphal, Manuela; Wansing, Gudrun (Hrsg.) (2019): Migration, Flucht und Behinderung. Herausforderungen für Politik, Bildung und psychosoziale Dienste Wiesbaden: VS. 326 S., € 29,99
(2021)
Manuela Westphal und Gudrun Wansing legen hier einen Folgeband zu „Behinderung und Migration“ (2014) vor, mit der eigenen Einschätzung, dass es sich um eine praxisnahe Fortsetzung handelt. Von einem gestiegenen fachlichen Interesse ist im Lichte der Fluchtzuwanderungen in den deutschsprachigen Raum seit 2015 auszugehen. Forschung und Praxisreflexionen an der Schnittstelle Behinderung/Flucht bleiben weiter hochaktuell und rar, weshalb der vorliegende Sammelband Anschlussfähigkeit an die Praxis verspricht. Er ist in ...
