1. GALILEO’S PENDULUM AS A MAGNETIC BALANCE FOR STUDYING CHEMICAL MAGNETISM AT HOME
A very simple, but rich experiment, encompassing a classical Galileo’s pendulum, has been devised to be performed at home, especially during the Covid-19 pandemics. The experiment uses a miniature supermagnet rod as the pendulum oscillating element suspended from a fixed sewing thread. Its physics can be fully investigated, allowing to study the oscillatio

2. KLOBUCHAR AND NEQUICK G IONOSPHERIC MODELS COMPARISON FOR MULTI-GNSS SINGLE-FREQUENCY CODE POINT POSITIONING IN THE BRAZILIAN REGION
Abstract One of the main error sources in GNSS positioning comes from the ionosphere, an atmospheric layer that stays in the signal path between the satellite and the receiver. For single frequency positioning, the ionospheric effects can be minimized by using an ionospheric model e.g. Klobuchar or NeQuick G. These models are respectively associated to GPS a

3. Relação da vegetação natural do Estado do Rio Grande do Sul com as disponibilidades climáticas
Resumo O clima do estado do Rio Grande do Sul (RS) é temperado úmido, condições de vegetação natural do tipo floresta temperada ou decidual, entretanto, em aproximadamente 46,3% de sua área, a vegetação é campestre. Assim, neste estudo, procurou-se colaborar no sentido de melhor entender as relações entre as condições climáticas e a vegetaçã

4. A new genus, a new species and taxonomic notes in Oxycoleini Martins & Galileo, 2003 (Coleoptera, Cerambycidae, Cerambycinae)
Abstract Oxylopsebus Clarke, 2008 is considered as a junior synonym of Oxycoleus Lacordaire, 1868. Equescollum is proposed as a new genus for E. birai sp. nov. from Costa Rica, which is described and illustrated.

5. Description of the female of Poeciloxestia plagiata (Waterhouse, 1880), and of the male of Iuati spinithorax Martins & Galileo, 2010 (Coleoptera, Cerambycidae)
Abstract Based on material recently collected in Peru (Loreto department) the female of Poeciloxestia plagiata (Waterhouse, 1880), and the male of Iuati spinithorax Martins & Galileo, 2010 are described and figured for the first time. Both species are recorded for the first time from Peru.

6. A new species of Malthonea Thomson, 1864 (Coleoptera, Cerambycidae, Lamiinae) from Ecuador
Abstract Malthonea keili, a new species from Ecuador, is described and illustrated. A key to species of Malthonea is provided. Photographs of the types of Malthonea minima, Prymnopteryx glaucina, Malthonea ruficornis, and Ptericoptus guttatus are provided as an aid to understanding the key (photographs of the types of the last three are provided for the firs

8. Fourier analysis of nonlinear pendulum oscillations
Since the times of Galileo, it is well-known that a simple pendulum oscillates harmonically for any sufficiently small angular amplitude. Beyond this regime and in absence of dissipative forces, the pendulum period increases with amplitude and then it becomes a nonlinear system. Here in this work, we make use of Fourier series to investigate the transition f

9. Phylogeny of the Neotropical longhorn beetle genus Ateralphus (Coleoptera: Cerambycidae: Lamiinae)
ABSTRACT Ateralphus Restello, Iannuzzi & Marinoni, 2001 is a Neotropical genus of longhorn beetles composed of nine species. This genus was proposed from splitting Alphus White, 1855 into other two genera: Ateralphus and Exalphus Restello, Iannuzzi & Marinoni, 2001. Even though Ateralphus (nine species), Alphus (four) and Exalphus (18) were recently revised,

10. Leonhard Euler's “principle of mechanics” (an essay on the foundations of the equations of motion)
Leonhard Euler derived equations of motion for both (in modern terminology) point mass mechanics and analytic mechanics. In order to derive the equations, some dynamic premise has to be introduced; this is the “principle of mechanics”. It stems from the recognition that infinitesimal motions are uniformly accelerated. Then, using Galileo Galilei's theore

11. Description of a new species of Adetus and of the female of Wappesoeme camiri, new records and updates to type depository for three species of Amphicnaeia Bates (Coleoptera, Cerambycidae)
ABSTRACT A new species of Adetus LeConte, 1852 is described from Bolivia. Additions to the description of Wappesoeme Galileo et al., 2015 and differences between males and females of Wappesoeme camiri Galileo et al., 2015 are provided. New country and state records are provided in Cerambycinae and Lamiinae. The type depository is corrected for three species

12. A non-hepatotropic parasite infection increases mortality in the acetaminophen-induced acute liver failure murine model: possible roles for IL-5 and IL-6
We evaluated the effects of a non-hepatotropic parasite infection (Taenia crassiceps) on the outcome of acetaminophen-induced acute liver failure in mice. Uninfected and T. crassiceps infected mice orally received either 300 mg/kg acetaminophen or water as vehicle (n = 5 per group). Survival analysis, hepatocyte necrosis, alanine aminotransferase (ALT) level
