Reducing.CH4 and N20 emissions from rice cropping.systems while sustaining.production levels with less water requires a better understanding.of the key processes involved. Alternate wetting.and drying.（AWD） irrig.tion is one promising.practice that has been shown to reduce CH4 emissions. However, little is known about the impact of this practice on N20 emissions, in particular under Mediterranean climate. To close this knowledg. g.p, we assessed how AWD influenced g.ain yield, fluxes and annual budg.ts of CH4 and N20 emissions, and g.obal warming.potential （g.P） in Italian rice systems over a 2-year period. Overall, a larg.r g.P was observed under AWD, as a result of hig. N20 emissions which offset reductions in CH4 emissions. In the first year, with 70% water reduction, the yields were reduced by 33%, CH4 emissions decreased by 97%, while N20 emissions increased by more than 5-fold under AWD as compared to PF; in the second year, with a 40% water saving. the reductions of rice yields and CH4 emissions （13% and 11%, respectively） were not sig.ificant, but N20 fluxes more than doubled. The transition from anaerobic to aerobic soil conditions resulted in the hig.est N20 fluxes under AWD. The duration of flooding. transition to aerobic conditions, water level above the soil surface, and the relative timing.between fertilization and flooding.were the main drivers affecting.g.eenhouse g.s mitig.tion potential under AWD and should be carefully planned throug. site-specific manag.ment options.

The increasing.use of bioabsorbable polymeric materials in medicine has stimulated researchers in the materials field to search for solutions for the replacement of metallic artifacts by bioabsorbable polymers. Therefore, this study describes the in vitro deg.adation of PHBV, PCL and the blends of these polymers, both of which are bioabsorbable polymers. The samples were prepared by extrusion followed by injection, and subjected submitted to in vitro deg.adation in phosphate buffered saline solution with pH 7.3 and kept at 37° C. Throug. the characterization of the variation of mass, molar mass, mechanical properties and morpholog., the results indicated that the samples analyzed are more stable to hydrolytic deg.adation when compared to other bioabsorbable polymers. The materials indicate sig.s of deg.adation after 30 days, with a small reduction in the molar mass. After 180 days, the materials indicated a sig.ificant reduction of molar mass and reduction in the mechanical properties.
