Peculiarities of stems flattening at two-phase fiber flax harvesting technology

open access: yesTractors and Agricultural Machinery, 2023
BACKGROUND: Based on the analysis of the morphological features of fiber flax, authors focus on the technical part of the stem, which contains fiber. To improve the quality and for most complete isolation of this product, the process of tissue maceration should be stimulated by stem flattening.

EFFECT OF HARVESTING DATES ON THE YIELD AND QUALITY OF SOME FLAX GENOTYPES

open access: yesArab 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 ...

Low Participation and Risk Reduction Potential of Supplemental Crop Insurance in the United States

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Federally subsidized crop insurance is a cornerstone of U.S. farm risk management, yet policies with the greatest share of participation only trigger indemnities after losses exceed 15%. Supplemental insurance was introduced to cover part of this deductible, but participation remains largely unchanged.

Circular Transformation in the Silk Sector: A Fuzzy Delphi–DEMATEL Analysis of Critical Factors

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The circular transformation in the silk industry is crucial for enhancing resource efficiency and minimizing waste. Despite growing interest in circularity within the textile sector, the silk industry remains underexplored. This study addresses this gap by systematically assessing the barriers and enablers influencing circular economy adoption

Effects of hybrid metal oxide nanoparticles on the tribological and emission attributes of algae‐derived biofuel in compression ignition engines

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract The growing demand for sustainable fuels has accelerated the development of algae‐derived biodiesel for compression‐ignition engines. In this study, Chlorella vulgaris methyl ester (AME) exhibited physicochemical properties comparable to diesel and satisfied ASTM D6751 fuel quality requirements, making it suitable for blending.

Influence of natural fibers on physical, mechanical, and fire‐resistant properties of microconcrete

open access: yesStructural Concrete, EarlyView.
Abstract This study examined the influence of natural fibers on the physical, mechanical, and fire‐resistant properties of microconcrete, in comparison with conventional polypropylene fibers used in cement composites. The fibers were characterized by FTIR and TGA/DSC to assess their composition and thermal stability, and FTIR was also performed after ...

LOW-QUALITY FLAX STRAW BIOMASS HARVESTING FOR SUBSEQUENT USE AS FUEL: A REVIEW

open access: yesСІЛЬСЬКОГОСПОДАРСЬКІ МАШИНИ, 2022
Unfavorable conditions for flax growing, harvesting and dew-retting are the reason for the low-quality flax biomass production. This biomass cannot be processed for fiber or other purposes. Therefore, flax straws are burned in the fields or are used as fertilizer by plowing into the soil, which are not good solutions for the environment and subsequent ...

HOST MATTER: Parasite infection drives chemical reconfiguration of decomposing host and shapes insect behavioural responses

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Host–parasite interactions shape ecosystems by driving species dynamics, yet their influence is typically considered in terms of host mortality rather than the chemical environments generated during infection and decomposition.
