hemp, and flax composites
This study characterizes the acoustical behavior of natural fiber composites. Regenerated cellulose fibers (Lyocell), hemp fibers, and flax fibers were embedded in an epoxy-matrix. These unidirectional composites were tested for their logarithmic damping decrement, the resonance frequency, the ultrasound velocity, the dynamic and static modulus of elasticity, and bending strength and density. G...

The archaeological evidence of flax cultivation dates back to >6000 BC and it is considered as one of the oldest and most useful crops. Components of flax have diverse uses. Cultivar development of flax is currently focused on enhancing the oil content and nutritional value to meet the demand of nutraceutical market supply, as an alternate source of fish oil, a rich source of eicosapentaenoic a...
متن کاملMortality of flax workers.
A total of 2528 workers in flax mills in Northern Ireland were followed up for 16 years. Follow-up was 97% complete. Deaths were identified and date and cause ascertained. Expected deaths were calculated on the basis of age and sex specific rates for Northern Ireland.

Unambiguous and quick identification of D variants is of immediate clinical relevance, with implications for transfusion strategy. STUDY DESIGN AND METHODS A total of 628 samples with ambiguous serologic results f...
متن کاملBiotechnology of Flax (Linum usitatissimum)
Biotechnology can offer useful tools to complement conventional breeding programs. The techniques of in vitro selection, that exploit phenomenon, called somaclonal variation, by screening cell cultures for resistance to herbicides, different types of stress or diseases, already helped to obtain tolerant lines of flax (Linum usitatissimum), which were used in further commercial breeding programs...
