This study of nesting and associated behavior patterns of Andrena patella was carried out at 27 locations with different landscape categories, from 2013 to 2016. The research areas chosen were generally flat or marshy areas. A total of 15 major nest aggregations were spotted and 120 nests were excavated. This species nests in soil, males emerge earlier than females, and mating occurred on flowers during the foraging season, in the 3rd week of May. The various nest and cell parameters showed low variability in the different years and different sites, but nest cell length, diameter and number varied significantly, as well as depth even at the same site. The nests were multi-cellular, oblique to horizontal, and cell shape was oval. The mating attempts of the pairs and copulatory behavior involved various steps which were completed in a very few seconds. The males appeared first on the flowers, near to the nesting site, and lived shorter than the females. The females started foraging in the 2nd to 3rd weeks of May and laid eggs in the 1st week of June. The adult phenology, egg placement, cell provision and larval feeding are described.

Abstract A three-component model for a belted radial tire, previously developed by the authors for free rolling without slip, is generalized to include longitudinal forces and deformations associated with driving and braking. Surface tractions at the tire-road interface are governed by a Coulomb friction law in which the coefficient of friction is assumed to be constant. After a brief review of the model, the mechanism of interfacial shear force generation is delineated and explored under traction with perfect adhesion. Addition of the friction law then leads to the inception of slide zones, which propagate through the footprint with increasing severity of maneuvers. Different behavior patterns under driving and braking are emphasized, with comparisons being given of sliding displacements, sliding velocities, and frictional work at the tire-road interface. As a further application of the model, the effect of friction coefficient and of test variables such as load, deflection, and inflation pressure on braking stiffness are computed and compared to analogous predictions on the braking spring rate.
