Seroprevalence of Contagious Caprine Pleuropneumonia in Selected Districts of Borana Zone, Oromia Region, Southern Ethiopia. [PDF]

Vet Med Sci
A cross‐sectional study, conducted on contagious caprine pleuropneumonia (CCPP) in the goat population, revealed a seroprevalence of 15.85% (95% CI: 12.06%–20.54%). Undertaking a broader research involving a larger‐scale study and reservoir species, including sheep, is recommended to gain deeper practical insights into the disease.

Aging of the Hematopoietic System: Mechanisms, Consequences, and Systemic Interactions. [PDF]

Aging Cell
Hematopoietic aging arises from intrinsic stem‐cell decline and bone‐marrow niche dysfunction, leading to myeloid skewing, immunosenescence, and clonal hematopoiesis. These changes drive systemic inflammation and multi‐organ disease, which in turn further disrupt the bone‐marrow niche and hematopoietic stem cell (HSC) function, creating a vicious cycle

Selective and non-selective bottlenecks as drivers of the evolution of hypermutable bacterial loci. [PDF]

Mol Microbiol, 2020
Bottlenecks produce dramatic reductions in the genetic diversity of bacterial populations. Bottleneck events can be selective or non‐selective and occur frequently, particularly during transmission between hosts. Multiple mutational strategies have evolved in bacteria that can regenerate genetic diversity within surviving populations following a major ...

River Damming Impacts on Fish Habitat and Associated Conservation Measures

Reviews of Geophysics, Volume 61, Issue 4, December 2023., 2023
Abstract River damming has brought great benefits to flood mitigation, energy and food production, and will continue to play a significant role in global energy supply, particularly in Asia, Africa, and South America. However, dams have extensively altered global river dynamics, including riverine connectivity, hydrological, thermal, sediment and ...

Reversible pigs

American Ethnologist, Volume 50, Issue 1, Page 115-128, February 2023., 2023
Abstract The idea of “species” is the main unit for representing ecological relations. But what would an ecology look like if we started by tracing its relations from below the species threshold? By deploying an infraspecies ethnography, I show how, in suburban Barcelona, human and wild boar individuals relate in personal, creative ways, and how in ...

Structural Defects Improve the Memristive Characteristics of Epitaxial La0.8Sr0.2MnO3‐Based Devices

Advanced Materials Interfaces, Volume 9, Issue 23, August 11, 2022., 2022
Asymmetric planar Pt/Ti/LSM\Pt (LSM=La0.8Sr0.2MnO3‐δ) memristive devices show clockwise log I(V) characteristics with gradual changes in resistance, and good retention and reproducibility, suitable for neuromorphic computing applications. Compared to defect‐free epitaxial LSM/SrTiO3 (STO) devices, the extended defects present in LSM/LaAlO3 (LAO) boost ...

Radiative and Aerodynamic Contribution to Evaporation: Eddy‐Covariance Comparison Between a Plain and a Plateau Lake

Earth and Space Science, Volume 8, Issue 10, October 2021., 2021
Abstract Water surface‐atmosphere interactions play an important role in the climate system on regional and even global scale. Yet, it remains unclear whether radiative or aerodynamic forces contribute more to water surface evaporation, which may lead to different strategies in model parameterization.

Persistence of microbiological hazards in food and feed production and processing environments. [PDF]

EFSA J
Abstract Listeria monocytogenes (in the meat, fish and seafood, dairy and fruit and vegetable sectors), Salmonella enterica (in the feed, meat, egg and low moisture food sectors) and Cronobacter sakazakii (in the low moisture food sector) were identified as the bacterial food safety hazards most relevant to public health that are associated with ...

Hydro-physical processes at the plunge point: an analysis using satellite and in situ data [PDF]

, 2011
The plunge point is the main mixing point between river and epilimnetic reservoir water. Plunge point monitoring is essential for understanding the behavior of density currents and their implications for reservoir.

Allozyme variation among three populations of the armored catfish Hypostomus regani (Ihering, 1905) (Siluriformes, Loricariidae) from the Paraná and Paraguay river basins, Brazil

Genetics and Molecular Biology, 2008
Three Brazilian populations of the armored catfish Hypostomus regani (Ihering, 1905) were sampled, one from the Corumbá Reservoir in Goiás state, another from the Itaipu Reservoir in Paraná state and a third from the Manso Reservoir in Mato Grosso state.
