A Modified Pressure–Sinkage Model for Studying the Effect of a Hard Layer in Sandy Loam Soil

open access: yesApplied Sciences, 2021
The applicability of the typical pressure–sinkage models used to characterize the soil’s bearing properties is limited to homogeneous soils (infinite thickness) that have no hard layer. At a given depth, a hard layer can have a considerable impact on the

Voice pitch preferences of adolescents: Do changes across time indicate a shift towards potentially adaptive adult-like preferences? [PDF]

open access: yes, 2013
An evolutionary approach to attractiveness judgments emphasises that many human trait preferences exist in order to assist adaptive mate choice. Here we test an adaptive development hypothesis, whereby voice pitch preferences indicating potential mate ...
