In this research, a method for producing gum tragacanth (GT) fibers is presented. Ribbon type GT of Astragalus Gummifer species were obtained from local production lands. The gum was treated with alkali to increase its process ability, and allowed to stand for a period of time to reach the proper viscosity and/or to "ripen". Samples with different ripening times were prepared and their viscosit...

We study conditions for the emergence of preformed Cooper pairs in materials hosting flat bands. As a particular example, we consider semimetal, with pair three-band crossing points at which band intersects Dirac cone, and focus on s-wave intervalley pairing channel. The nearly dispersionless nature strong attraction between electrons promotes local formation so that system may be modeled as an...

[1] We use both theory and ocean biogeochemistry models to examine the role of the soft-tissue biological pump in controlling atmospheric CO2. We demonstrate that atmospheric CO2 can be simply related to the amount of inorganic carbon stored in the ocean by the soft-tissue pump, which we term (OCSsoft). OCSsoft is linearly related to the inventory of remineralized nutrient, which in turn is jus...

Conifer defenses against bark beetle attack include, but are not limited to, quantitative and qualitative defenses produced prior to attack. Our objective was to assess host defenses of lodgepole pine and ponderosa pine from ecotone stands. These stands provide a transition of host species for mountain pine beetle (Dendroctonus ponderosae; MPB). We asked two questions: (1) do the preformed quan...
