Natural adhesive systems are adapted to attach to rough surfaces, but the underlying mechanisms have not been fully clarified. Attachment forces for the beetle Gastrophysa viridula were recorded on epoxy casts of surfaces with different roughness using a centrifuge device. Replicas were made of standardized polishing paper with asperity sizes ranging from 0.05 to 30 μm and of dock leaves （Rumex obtusifolius）. Beetles adhered with a safety factor of up to 36 times body weight on smooth substrates or on casts of leaves of their host plant. On the rough substrates, forces were much lower and a minimum at small scale roughness （0.05μm asperity size, with a mean safety factor of S） was observed. Removal of the claws led to a significant reduction in force for rough substrates with asperity sizes ≥ 12 μm. Attachment forces of the hairy adhesive system itself（without the claws） slightly increased from small-scale to large-scale surface roughness, but remained below the level seen on the smooth substrate. This is explained by the inability of setal tips to make full contact to the surface.

The crystallization kinetics of Sn4oSe6o thin films has been successfully investigated using sheet resis- tance versus temperature measurements. Thermal evaporation was used to deposit the films on ordinary glass sub- strates. The crystallization temperature for Sn4oSe60 thin film was found to be 156.6 -t- 0.3 ~C. In the as-deposited state, the sheet resistance was found to be 195 mf2/[2, this value declined to 1560 f2/[2] upon annealing. The value of activation energy obtained from the Kissinger plot was 0.62 ＋ 0.07 eV. From the results obtained, SnaoSe60 is a promising alloy for PCm application because of its high electrical contrast, high crystallization temperature, and relatively high activation energy.

When collecting a flower,bumblebees learn to associate floral features with reward,preferring,and specializing in the most profitable ones they visit(Chittka et al.1999).The proboscis extension reflex(PER)occurs naturally in the feeding context allowing individuals to access the floral *** controlled conditions,the PER paradigm is a well-established controlled learning procedure used in honeybees(Takeda 1961),and some bumblebees of the genus Bombus(Laloi et al.1999).The assessment of cognitive capacities in an operant context has been studied mainly in *** and ***(Chittka 1998;mirwan and Kevan 2014).However,little is known about the ability to evoke associative memories in an operant context,which had been acquired in a classical *** turn,on the contrary,the Bombus genus also has the capacity to form longterm memories(Chittka 1998;mcAulay et al.2015).In particular,the South American bumblebee ***(***)can learn a pure odor when it is presented in a paired association with a sugar reward within a PER paradigm(Palottini et al.2018).As other species,this one is a commercially reared pollinator that is increasingly managed in pollination services of some South American countries and they could be important for increasing production of crops(Palottini et al.2018).
