Stable isotopes reveal the common winter moult of central rectrices in a long‑distance migrant songbird
(Springer Link, 2019)
By analysing the deuterium concentration in the scapulars and rectrices (δ2Hf) of breeding and spring migrating Ortolan
Buntings (Emberiza hortulana), we found a high correlation attesting that spring body and central ...
Effects of selected inorganic chemical activators on properties and hydration mechanism of high volume fly ash (HVFA) binders
(Elsevier Ltd., 2023)
Effects of Na2SO4, Na2CO3, and Na2SiO3 on setting time, compressive strength (up to 90 days), and hydration mechanism of binders with high volume (70 wt%, HVFA binders) of fly ash (FA) were investigated. Before chemical ...
Electrical and sensing properties of indium-doped barium cerate
(Elsevier LtdTechna Group S.r.l., 2023)
Systematic analysis of electrical characteristics of BaCe0.75In0.25O3-δ (BCI25) sintered sample was performed in a
dry and a wet argon atmosphere in the 250 ◦C–700 ◦C temperature range. The water vapor sensing properties ...
What’s the rumpus? Resident temperate forest birds approach an unfamiliar neotropical alarm call across three continents
(The Royal Society, 2023)
Alarm signals have evolved to communicate pertinent threats to conspecifics,
but heterospecifics may also use alarm calls to obtain social information. In
birds, mixed-species flocks are often structured around focal ...
Synthesis and thermal stability of cis-dichloro[(E)-ethyl-2-(2-((8- hydroxyquinolin-2-il)methylene)hidrazinyl)acetate-κ2N]-palladium(II) complex
(Springer Science & Business MediaAkadémiai Kiadó, 2017)
The structure of new cis-dichloro[(E)-ethyl-2-(2-
((8-hydroxyquinolin-2-il)methylene)hidrazinyl)acetate-j2N]-
palladium(II) complex was determined using a combination
of XRD and IR measurements and DFT calculations.
Inherent ...
Ductile-to brittle transition of ferritic steels: A historical sketch and some recent trends
(Elsevier, 2023)
The phenomenon of ductile-to-brittle transition in ferritic steels has been a ubiquitous research challenge
for the last 50 years. The characterization of this problem using the fracture mechanics concept, from the
earliest ...
A three-step process of manganese acquisition and storage in the microalga Chlorella sorokiniana
(Oxford University Press, 2023)
Metabolism of metals in microalgae and adaptation to metal excess are of significant environmental importance. We report a three-step mechanism that the green microalga Chlorella sorokiniana activates during the acquisition ...
An Eco-friendly Approach to ZnO NP Synthesis Using Citrus reticulata Blanco Peel/Extract: Characterization and Antibacterial and Photocatalytic Activity
(American Chemical Society, 2024)
Emission of greenhouse gases and infectious diseases caused by improper agro-waste disposal has gained significant attention in recent years. To overcome these hurdles, agro-waste can be valorized into valuable bioactive ...
Uptake of vanadium and its intracellular metabolism by Coprinellus truncorum mycelial biomass
(Elsevier Gmbh, Munich, 2024)
BACKGROUND
Fungi absorb and solubilize a broad spectrum of heavy metals such as vanadium (V), which makes them a main route of its entry into the biosphere. V as vanadate (V5+) is a potential medical agent due to its many ...
Determinants of avian malaria prevalence in mountainous Transcaucasia
(Springer Link, 2018)
Deforestation, urban development, and global climate change can lead to dramatic changes of ecological communities and increase
prevalence of infectious diseases at higher latitudes and altitudes. Identification of factors ...
