Introduced dung beetles suppress methane emissions from cattle dung and alter the temporal dynamics of greenhouse gas flux Los escarabajos peloteros introducidos suprimen las emisiones de metano del estiércol de ganado y alteran la dinámica temporal del flujo de gases de efecto invernadero Besouros coprófagos introduzidos suprimem as emissões de metano do esterco bovino e alteram a dinâmica temporal do fluxo de gases de efeito estufa

Ecological Entomology, EarlyView.
Dung beetles suppressed cumulative methane flux from cattle dung by 85% and reduced total greenhouse gas emissions by 18%. Beetle activity accelerated initial CO2 release but did not alter total cumulative flux. N2O and NH3 fluxes were transient and not consistently driven by beetle presence.

Characterization of Spin-Coated Polymer Films

Journal of the Brazilian Chemical Society, 2002
In this work the morphology of spin-coated polymer films is explained based on the competitive interactions between polymer, solvent and substrate. The films were formed on silicon wafers, a polar surface.

Chemical Degradation of Rigid PVC Film

Chemical Degradation of Rigid PVC Film
The chemical degradation of rigid PVC film in nitric acid solution has been studied in the range of 30 to 80℃ from intrinsic viscosity measurements. It was found that degree of polymerization of PVC decreased remarkably as a result of oxydation and that at 60℃ and above a part of degraded polymer dissolved in nitric acid solution.

Evaluation of physical, chemical, and color‐matching properties of monochromatic resin composites: An in vitro study

European Journal of Oral Sciences, EarlyView.
Abstract The objectives of this study are to evaluate, in vitro, the microhardness, sorption, solubility, color stability, and color‐matching ability of monochromatic resin composites: Palfique Omnichroma / Tokuyama (Mono1) and Vittra APS Unique / FGM (Mono2) compared with the conventional resin composite: Filtek Z250 XT / Solventum (Conv).

Size‐selective mortality evolutionarily alters collective behaviour in response to predation risk in a zebrafish (Danio rerio) harvest‐induced selection model

Journal of Fish Biology, EarlyView.
Abstract Intensive multigenerational size‐selective mortality has been found to alter collective properties like shoaling via evolutionary adaptations of individual‐level behavioural traits. For example, experimental populations of zebrafish (Danio rerio) experiencing intensive large size‐selective mortality over multiple generations developed less ...

Influence of X‐ray beam angulation on the radiographic detection of implant–abutment interface misfits: A quantitative in vitro analysis

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study evaluated the effect of periapical X‐ray angulation on the diagnostic accuracy of detecting vertical misfits at the implant–abutment interface using Medentika Microcone dental implants (4.0 mm diameter, 11 mm length; internal conical connection).
