Analysis of molecular mobility in corn and quinoa flours through ¹H NMR and its relationship with water distribution, glass transition and enthalpy relaxation por Rolandelli, Guido, Farroni, Abel Eduardo, Buera, María del Pilar

“…Enthalpy relaxations, identified by thermal analysis at 50–70 °C were studied through transverse relaxation times (T2) measured after Hahn spin-echo sequence, which revealed a rearrangement of the biopolymers structures that cause immobilization of polymer chains and reduced mobility of water molecules with weak interactions with solids (lower T22). …”

The positive effect of plant diversity on soil carbon depends on climate por Spohn, Marie, Bagchi, Sumanta, Biederman, Lori A., Borer, Elizabeth T., Bråthen, Kari Anne, Bugalho, Miguel N., Caldeira, Maria C., Catford, Jane A., Collins, Scott L., Eisenhauer, Nico, Peri, Pablo Luis, Yahdjian, Laura

“…Yet, this knowledge is of crucial importance in times of climate change and biodiversity loss. Here, we show that plant diversity is positively correlated with soil carbon content and soil carbon-to-nitrogen ratio across 84 grasslands on six continents that span wide climate gradients. …”

Actividad fito-estrogénica del trébol blanco in vitro e in vivo y su fluctuación en relación a variables climáticas. Estado metabólico y fermentación ruminal por Gil, L.A, Díaz, M.C, Ramírez, J, Mayorga, M.

“…These effects were similar in both the injected application and the oral application, although accumulated oral doses contain one hundred times the amount in infected doses. The fermented extract, administered orally, appears to have affected fertility more than the fermented extract, but parenteral action was undifferentiated.…”
