factors hindering the development of inundative biological control are insect rearing costs and provide an adequate amount of natural enemies at the appropriate time. storage of natural enemies is a useful technique to increase time flexibility of parasitoids production, and coincide the natural enemies release with pest outbreaks period, and also could reduce costs of mass production. another ...

conclusions this study indicated that the rv systolic strain and strain rate can be used to detect early rv systolic dysfunction in ssc patients without pulmonary hypertension. these parameters may be useful for the provision of a more adequate management of ssc patients. results in the ssc patients, the rv strain (- 19 ± 10 vs. - 25 ± 4 %; p = 0.004) and the systolic strain rate (- 1.3 ± 0.5 v...

The mechanical response of Polyethylene Terephthalate (PET) in elongation is strongly dependent on temperature, strain and strain rate. Near the glass transition temperature Tg, the stress-strain curve presents a strain softening effect vs strain rate but a strain hardening effect vs strain under conditions of large deformations. The main goal of this work is to propose a viscoelastic model to ...
