Autor: Zubieta, E., Garcia, F., del Palacio, S., Furlan, S. B. Araujo, Gancio, G., Lousto, C. O., Combi, J. A., Espinoza, C. M.

Context. Pulsars have a very stable rotation. However, sudden increases in their rotation frequency known as glitches, perturb their evolution. While large glitches are commonly detected, small glitches are harder to detect because of the lack of dai

Pulsar Observations at low latitudes and low frequencies

Autor: Lousto, Carlos O., Missel, R., Zubieta, E., del Palacio, S., Garcia, F., Gancio, G., Wang, L., Furlan, S. B. Araujo, Combi, J. A.

The Pulsar Monitoring in Argentina (PuMA) is a collaboration between the Argentine Institute for Radioastronomy (IAR) and the Rochester Institute of Technology (RIT) that since 2017 has been observing southern sky pulsars with high cadence using the

Adapting and Verifying the Liming Index for Enhanced Rock Weathering Minerals as an Alternative Liming Approach

Autor: Francisco S. M. Araujo, Andrea G. M. Chacon, Raphael F. Porto, Jaime P. L. Cavalcante, Yi Wai Chiang, Rafael M. Santos

Publikováno v: Land, Vol 13, Iss 11, p 1839 (2024)

Acidic soils limit plant nutrient availability, leading to deficiencies and reduced crop yields. Agricultural liming agents address these issues and are crucial for deploying silicate amendments used in enhanced rock weathering (ERW) for carbon seque

Sarcocystis cruzi (Hasselmann, 1923) Wenyon, 1926: redescription, molecular characterization and deposition of life cycle stages specimens in the Smithsonian Museum

Autor: J. P. Dubey, Aditya Gupta, Larissa S. de Araujo, Oliver C. H. Kwok, Asis Khan, Benjamin M. Rosenthal

Publikováno v: Parasitology, Vol 150, Pp 1192-1206 (2023)

Currently, 7 named Sarcocystis species infect cattle: Sarcocystis hirsuta, S. cruzi, S. hominis, S. bovifelis, S. heydorni, S. bovini and S. rommeli; other, unnamed species also infect cattle. Of these parasites of cattle, a complete life cycle descr

Potential use of pepper waste and microalgae Spirulina sp. for bioelectricity generation

Autor: W. Rojas-Villacorta, S. Rojas-Flores, Santiago M. Benites, D. Delfín-Narciso, M. De La Cruz-Noriega, L. Cabanillas-Chirinos, H. Rodríguez-Serin, S. Rebaza-Araujo

Publikováno v: Energy Reports, Vol 9, Iss , Pp 253-261 (2023)

The research aimed to generate bioelectricity using pepper waste and the microalgae Spirulina sp by a double-chamber microbial fuel cell (dcMFC). A dcMFC was constructed with Cu and Zn electrodes, where organic waste and microalgae were placed in the

Publikováno v: Emerging Infectious Diseases, Vol 29, Iss 5, Pp 977-987 (2023)

Combining genomic and geospatial data can be useful for understanding Mycobacterium tuberculosis transmission in high-burden tuberculosis (TB) settings. We performed whole-genome sequencing on M. tuberculosis DNA extracted from sputum cultures from a

Cluster size effects in the magnetic properties of Fe$_p$-Al$_{q=1-p}$ alloys

Autor: Santos-Filho, João B., Santos, Alan V., Batista, Tatiana S. de Araujo, Plascak, João A.

A spin-1/2 Ising model, defined in the body centered cubic lattice, is used to describe some of the thermodynamic properties of Fe$_p$-Al$_q$ alloys, with $p+q=1$. The model assumes, besides the nearest-neighbor exchange coupling, the existence of fu
