Process-Property Relationships for Melt-Spun Poly(lactic acid) Yarn.

Poly(lactic acid) (PLA) is an attractive biomaterial due to its biocompatibility, biodegradability, and fiber-forming ability. However, the polymer is highly susceptible to both hydrolytic and thermal degradation during processing. Melt processing conditions typically involve high temperature and shear, whereas to prevent premature degradation, PLA needs to be processed under the mildest conditions that still yield the desired yarn properties.

Border Habitat Effects on Captures of (Hemiptera: Pentatomidae) in Pheromone Traps and Fruit Injury at Harvest in Apple and Peach Orchards in the Mid-Atlantic, USA.

The invasive invades crop fields from various bordering habitats, and its feeding on crops has caused significant economic losses. Thus, is considered a perimeter-driven threat, and research on alternative management tactics against it has focused on intervention at crop edges. Woodlands adjacent to crop fields contain many hosts of and are therefore considered "riskiest" in terms of pest pressure and crop injury.
