“…Herein, we extracted taxanes from Taxus cuspidata via PEF and explored the effects of seven extraction conditions on the yields of target compounds. The Placket–Burman design (PBD) assay revealed that electric field strength, pulse number, and particle size are key factors for taxanes extraction. …”

“…The optimal levels of the most significant identified variables affecting the adsorption process were sequential determined by the response surface methodology (RSM) using Plackett–Burman and Box–Behnken designs. The gained results denoted that the surface of SGO@CA beads displayed the higher negative charges (− 42.2 mV) compared to − 35.7 and − 38.7 mV for pristine CA and SGO, respectively. …”

“…We firstly confirmed that ‘HFBZ’ and ‘LFBZ’ fruit showed respiratory climacteric by detecting respiratory rate and ethylene emission during post-harvest; found that esters were the major aroma components in ‘HFBZ’ fruit, and hexyl 2-methylbutyrate was responsible for the ‘fruity’ note and most potent aroma component, followed by ethyl acetate, ethyl butanoate, (E)-2-hexenal, and 1-hexanol. Regarding aroma synthesis, fatty acid metabolism seemed to be more important than amino acid metabolism for aroma synthesis in ‘HFBZ’ fruit. …”

“…The INA level of bud scales was not high in late August when flower bud formation was ending, but increased to reach the highest level in late October just before the first autumnal freeze. The results support the following hypothesis: the high INA in bud scales functions as the subfreezing sensor, ensuring the primary freezing in bud scales at warmer subzero temperatures, which likely allows the migration of floret water to the bud scales and accumulation of icicles within the bud scales. …”

“…Es claro que, durante los últimos 30 años, el sector empresarial se ha enfocado en las necesidades y preocupaciones de la sociedad (que se conectan directamente con la globalización y estilo de vida) más que en la creación e imposición de productos, debido a que buscan brindar soluciones y atender conflictos propios de cada época.A la vez, la inclusión de compliance permite que sea más fácil la gestión de operaciones, la previsión de riesgos, así como la consolidación de una imagen, ya que esta herramienta le agrega valor económico a la empresa, considerándose una inversión obligada.Son muchos los parámetros que un buen programa de compliance debe cubrir, sin embargo, en este trabajo, se abordarán tres temas que son de suma importancia hoy en día: el compliance, el medio ambiente, -que se ha convertido en uno de los principales aspectos de regulación paras las empresas- y la fusión entre ellos, para mejorar la operatividad al margen del respeto de lo derechos humanos y el desarrollo sustentable.…”
