The leaves, stems and whole plant of Ilex paraguariensis (yerba mate) were characterized in terms of their chemical composition and biological activities in order to determine which part of the plant is more interesting to develop bioactive formulations. The yerba mate samples contain at least five free sugars, five organic acids, eighteen fatty acids, one tocopherol, nine hydroxycinnamoyl deri...

Our modelling approach shows the predominance of facilitative over competition effects in controlling regeneration studied species, thus pointing out to intra- and inter-specific coexistence mechanisms. Natural is a main issue management continental Mediterranean forests. Ensuring natural forest therefore vital for preserving ecosystem function under climate warming increased frequency intensit...

In this paper we construct a global, continuous flow of solutions to the Camassa-Holm equation on the entire space H. Our solutions are conservative, in the sense that the total energy ∫ (u + ux) dx remains a.e. constant in time. Our new approach is based on a distance functional J(u, v), defined in terms of an optimal transportation problem, which satisfies d dtJ(u(t), v(t)) ≤ κ · J(u(t), v(t)...

Knowing one's mate value (mate-value accuracy) is an important element in reproductive success. We investigated within- and between-sex differences in this ability in a real-life speed-dating event. A total of 190 men and 192 women filled out a personality questionnaire and participated in speed-dating sessions. Immediately after each date, participants recorded who they would choose as mates a...

To date, the study of collective behaviour has mainly focused on intraspecific situations: the collective decision-making of mixed-species groups involving interspecific aggregation-segregation has received little attention. Here, we show that, in both conspecific and heterospecific groups, the larvae of two species (Lucilia sericata and Calliphora vomitoria, calliphorid carrion-feeding flies) ...

Mastopexy associated with augmentation for small vol­ ume and mild ptotic breasts has historically challenged plastic surgeons’ creativity. The perfect balance between breast volume, scar, shape, and long­lasting results has been the main focus of the work of many authors. Circumareolar, periareolar, and donut mastopexy are different names for a common approach to patients with a ptotic breast....
