The impact of green bond issuance on carbon emission intensity and path analysis.

Reducing carbon emission intensity is crucial for achieving sustainable development. Carbon emission intensity is expressively affected by the issuance of green bonds. Thus, it is imperative to assess the influence of green bond issuance on carbon emissions and examine their correlation.

[The study on the treatment of Oviducts Ranae protein with enzyme hydrolysis].

The paper introduced a process to enhance the yield of Oviducts Ranae protein using in vitro enzyme hydrolysis. The treatment process included two steps: (1) a 3 - 4 h of hydrolysis of a 0.025 g x g(-1) concentration of substance, at pH 7 and 60 degrees C, using 4% of papain; and (2) followed with a 6 - 8 h hydrolysis, at pH 2 - 2.
