Two sets of opaque water-based acrylic coatings were prepared with IR-reflective pigments and conventional pigments. The objective of this work was to determine the efficiency of IR-reflective pigments in limiting the heat buildup of opaque coating formulations. Experiments performed on PVC substrates revealed that IR-reflective pigments significantly decreased the temperature increase above ro...

Colony defense by social wasps includes aggressive behavior and camouflage with a high diversity of adaptation their nests to the environment, including substrate choice. The objective this study was present new data on nesting colony Neotropical Metapolybia cingulata docilis (Hymenoptera: Vespidae). Field observations were made January 4th 5th, 2022 at State Park Iguaçu, state Paraná, Brazil, ...

By-products of the agri-food sector are increasingly employed in production new organic preparations, with biofertilizer and biostimulating functions, thus reducing consumption non-renewable resources turning chains towards circular economy sustainability. Two composts were produced solid digestate (85%) as a common component different sources recyclable materials (15%): vine pruning wood (comp...

Traumatic Brain Injury (TBI) in all degrees of injury severity mainly induces deviant cognitive, emotional and behavioral alterations that lead to their respective disorders. This brief overview strives to define the variables that determine the risk of occurrence of these disorders and to describe the common patterns of these disorders and their relevant neuropathogenetic mechanism(s). In addi...

in this paper coupled nonlinear equations of motion of a suspended cable with time dependent tension and velocity are derived by using hamilton’s principal. a modal analysis for a stationary sagged cable is initially carried out in order to identify the dynamic system. the natural solution is directed to compute the natural frequencies and mode shapes of the free vibration of a suspended cable....

Two-dimensional superlattices of organically passivated 2.6-nm silver quantum dots were prepared as Langmuir monolayers and transferred to highly oriented pyrolytic graphite substrates. The structural and electronic properties of the films were probed with variable temperature scanning tunneling microscopy. Particles passivated with decanethiol ~interparticle separation distance of ;1.160.2 nm)...
