Release experiments as an indicator of flying activities of stingless bees in urban areas

Autor: Mariana V. N. Arena, Rogério H. Toppa, Marcos Martines, Isabel Alves-dos-Santos

Publikováno v: Frontiers in Sustainable Cities, Vol 4 (2023)

Contemporary urban ecology views cities as heterogeneous and dynamic ecosystems, composed of biotic, physical, social, and man-made systems. In this context, urban beekeeping stands out as a growing practice that demands further studies. Many species

Factors affecting faecal glucocorticoid levels in domestic cats (Felis catus): a pilot study with single and large multi-cat households

Autor: Priscila Viau, Archivaldo Reche-Junior, Angélica da Silva Vasconcellos, Alexandre Gonçalves Teixeira Daniel, Daniela Ramos, Cláudio Alvarenga de Oliveira, M. N. Arena, M. V. C. Albino

Domestic cats (Felis catus) are widely believed to be highly sensitive to the effects of social stress, especially when living in high density populations. Cats are capable of adapting to living in a group, but this will often require opportunities f

Forward and backward electron emission cross-sections for 23 MeVu-1 C , Ni and Au projectiles traversing C , Al , Ni , Ag , Au and Bi foils

Autor: A. Anzalone, G. Lanzano, M. Geraci, N. Arena, C. Volant, Hermann Rothard, E. De Filippo, F. Giustolisi, A. Pagano

Publikováno v: The European Physical Journal A. 32:349-356

A rather complete experimental study of forward and backward electron velocity spectra from thin foils bombarded with ions at constant velocity of 30 atomic units (23MeV u^-1) was performed. Three different beams ( 12C3+ , 58Ni14+ and 197Au36+ and si

Fast electron production in collisions of swift heavy ions (20MeV/u

Autor: A. Anzalone, Hermann Rothard, G. Lanzano, N. Arena, C. Volant, A. Pagano, F. Giustolisi, E. De Filippo, M. Geraci

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 233:31-42

In nuclear and atomic experiments at high incident ion energies, 20 MeV/ u E u , the impact of swift heavy ions on thin solid targets is a source of fast electrons. The knowledge of their spatial and kinematical distributions is very useful for exper

Fast-electron ejection from C, Ni, Ag and Au foils by 36 Ar 18 + (95 MeV/u): Measurements of absolute cross-sections

Autor: C. Volant, Sebastiano Aiello, A. Anzalone, G. Lanzano, F. Giustolisi, N. Arena, Hermann Rothard, A. Pagano, E. De Filippo, M. Geraci

Publikováno v: The European Physical Journal A. 21:169-174

Doubly differential electron velocity spectra induced by 36Ar18 + (95 MeV/u) from thin target foils (C, Ni, Ag, Au) were measured at GANIL (Caen, France) by means of the ARGOS multidetector and the time-of-flight technique. The main features observed

Recent results on fast intermediate velocity electron production induced by 19 + 45 A MeV 58 Ni highly charged ions on thin solid targets

Autor: C. Volant, Hermann Rothard, G. Lanzano, M. Geraci, Angelo Pagano, E. De Filippo, A. Anzalone, N. Arena, F. Giustolisi

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 205:841-846

In order to study the emission of energetic electrons induced by the impact of swift heavy ions on thin solid targets, we carried out a series of experiments at the superconducting cyclotron of the Catania Laboratori Nazionali del Sud. We report resu
