Analyzing the Process of Formation and Retaining of Straightness of Flax Stem Strips during Flax Harvesting

Engineering technologies and systems
Introduction. The effectiveness of flax cultivation largely depends on the degree of mechanization of harvesting processes. At the same time, a high productivity of flax stem pick-ups with minimal product losses can be ensured only when working on straight flax stem strips.Aim of the Study.

Adsorption Mechanisms and AI‐Driven Discovery of Biomass‐Based CO2 Sorbents

Small, EarlyView.
This review analyzes recent advances in biomass‐derived activated carbons for CO2 capture. It highlights the influence of precursors, activation methods, and surface modifications on adsorption performance. The integration of AI‐driven approaches for material optimization is discussed.

Market regulation and productivity: The case of the Canadian Wheat Board

American Journal of Agricultural Economics, EarlyView.
Abstract Changes to regulatory environments influence firm‐level incentives, which can move the productivity frontier or reposition firms within an existing frontier. Estimating causal effects of policy changes requires a credible counterfactual for productivity in the absence of policy change.

Evaluation of Camelina Sativa as an Alternative Oilseed Crop [PDF]

, 1999
End of Project ReportThe increasing awareness of the value of oils with a low content of saturated fat and a high proportion of OMEGA-3 to OMEGA-6 type fatty acids has focused attention on finding commercial sources of such oils.

Harvesting benefits: Exploring the effects of second‐best policies on enhancing soil organic carbon stocks in agriculture

American Journal of Agricultural Economics, EarlyView.
Abstract Agricultural subsidies can be an effective policy tool to enhance soil organic carbon sequestration. This paper assesses the effectiveness of a second‐best hypothetical policy which subsidizes additional canola hectares optimally for each soil zone in Saskatchewan in an effort to increase soil organic carbon.

The yielding capacity and plant stand of fiber flax with respect to the plant stand density before harvesting

, 2021
The fiber flax yielding capacity and plant stand prove to be the factors affecting the choice of the operation regimes of flax harvesters, whereas the changes and variability of morphological characters of stalks compli-cates their technological adjustment, thus making it impossible to use mechanization means under preparing and harvesting dew retted ...

From rhetoric to measurement: The economics of wetland conservation

Canadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract Wetland conservation continues to be a pressing issue as wetlands continue to be lost due to urban, industrial, and agricultural expansion. This paper synthesizes the current knowledge about wetland conservation economics in Canada, with a focus on prairie landscapes. We review the methods economists use to empirically measure the costs (i.e.,

Erweiterung der Studie «Torf und Torfersatzprodukte im Vergleich» : Eigenschaften, Verfügbarkeit, ökologische Nachhaltigkeit und soziale Auswirkungen [PDF]

, 2019
Der Abbau von Torf ist mit relevanten Treibhausgasemissionen verbunden und führt zur Zerstörung sensibler Ökosysteme. Aus diesem Grund bestehen in den Garten- und Gemüsebau-Branchen Bestrebungen, den Torf-verbrauch zu reduzieren.

Utilising plant‐derived dyes for designed changeability in textiles

Coloration Technology, EarlyView.
Abstract Natural plant extracts have been used for dyeing textiles since prehistoric times. With the discovery of synthetic dyes in 1856, the consumption of natural dyes declined sharply. However, the current focus on closed‐loop systems, the circular economy and the promotion of sustainable industries aimed at reducing environmental impact (eg, The ...
