On the Mechanical and Thermal Behavior of PLA, PBAT, and PHBV‐Based Ternary Blends and the Effect of Short Flax Fibers as Reinforcing Agents

open access: yesPolymer Composites, EarlyView.
Preparation and testing of biodegradable polymer ternary blends and composites with short flax fibres. ABSTRACT Bioplastics offer environmental benefits but they are costly and exhibit lower mechanical and thermal performance compared to fossil‐based counterparts. Poly(butylene adipate‐co‐terephthalate) (PBAT) exhibits high ductility but relatively low

Las limitaciones de la matriz hobbesiana en la actualidad política

open access: yesDoisPontos, 2009
In the present article we make two Hobbesian problems converge, to wit, what we call “Hobbesian Matrix” of the contemporary political culture and the “decisionist” aprouch of the order.

Mechanical, Thermal, and Morphological Behavior of Sustainable PC/ASA Composites Reinforced With Walnut Shell Powder

open access: yesJournal of Polymer Science, EarlyView.
Processing scheme of walnut shell reinforced PC/ASA biocomposites. ABSTRACT This study explores the effect of walnut shell (WS) powder as a bio‐based filler on the mechanical and thermal performance of polycarbonate (PC)/acrylonitrile–styrene–acrylate (ASA) composites.

RESULTS OF OPTIMIZATION OF PARAMETERS AND OPERATING MODES OF THE DISK PNEUMATIC SOWING DEVICE

open access: yesСельскохозяйственные машины и технологии, 2015
Technological effectiveness and qualitative characteristics of pneumatic sowing devices are higher than ones of lots produced rollers for a number of reasons, caused by decrease in number of doubles, increased evenness of seeds in a row.

Bio‐Based Multilayer Composites Based on Blended Electrospun Fibers and Luffa Cylindrica for Enhanced Low‐Frequency Noise Absorption

open access: yesJournal of Polymer Science, EarlyView.
Bio‐based multilayer composites consisting of Luffa Cylindrica and electrospun microfibers exhibit enhanced sound absorption, shifting peak performance towards lower frequencies. The multilayer configuration improves acoustic wave dissipation, providing a tunable and sustainable solution for urban and traffic‐related noise mitigation.

Global Health Governance Cannot Keep Relying on the Development‐Goals Model to Effectively Address Health Inequalities Around the World

open access: yesSustainable Development, EarlyView.
ABSTRACT The Sustainable Development Goals (SDGs) are nearing their end in 2030, and it is highly unlikely that many of the SDGs would be met by the target date. This calls for the urgent need for an upgraded approach or a new strategy from the “development‐goals” model.

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

open access: yesAmerican 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.

Cell wall gene expression in two sub-species of flax

open access: yesThe EuroBiotech Journal, 2017
In this work, we attempted to elucidate mechanisms of flax fiber biogenesis by measuring, using qPCR, expression of the cellwall related genes (cellulose synthase, cellulose synthase-like and chitinase-like genes) in stems of two contrasting fiber ...
