Journal 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.

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.

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.

EFFECT OF HARVESTING DATES ON THE YIELD AND QUALITY OF SOME FLAX GENOTYPES
Arab Universities Journal of Agricultural Sciences, 2010 ABSTRACT Two field experiments were conducted during the two successive seasons 2007/2008 and 2008/2009 at Sakha Agric. Res. Station, Kafr El-Sheikh Governorate to study the effect of four harvesting dates i.e. 135, 145, 155 and 165 days after sowing on yield and its quality of six flax genotypes namely, Sakha1, Sakha 2, Sakha 3 and Giza 9 varieties ...

Engineering technologies and systemsIntroduction. 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.
