Bioarcheological Perspectives on the Timing of Adolescence in Rural Avar‐Age Austria, 7th–9th Centuries ce

open access: yesAmerican Journal of Biological Anthropology, Volume 188, Issue 1, September 2025.
ABSTRACT Objectives This study provides insights into adolescent development during the early medieval period in Austria and offers a point of comparison of the timing of sexual maturation relative to the Imperial Roman and the late medieval periods. Materials and Methods The timing of adolescent development of 89 individuals in two rural cemeteries ...

Some Vegetable Oil‐Based Additives for Petroleum Industry: A Review of Sunflower, Rapeseed and Used Cooking Oil‐Derived Surfactants

open access: yesEngineering Reports, Volume 7, Issue 9, September 2025.
Green additives in the petroleum industry: Vegetable oil‐based surfactants and EP additives offer a sustainable alternative for the petroleum industry. ABSTRACT The increasing environmental concerns associated with conventional petroleum‐based additives—such as high toxicity, poor biodegradability, and long‐term ecological persistence—have driven the ...

Variation in DRD4 gene methylation in wild great tits is associated with behavioural tolerance to human disturbance but not with habitat urbanization

open access: yesJournal of Avian Biology, Volume 2025, Issue 5, September 2025.
The increasing presence and activities of people in both urban environments and non‐urban areas result in the exposure of many wild animal populations to persistent human disturbance. As a response, individuals in disturbed populations often become tolerant towards humans, which can have significant ecological and societal consequences, for example by ...

Is High‐Touch Enough? Personalization‐Supporting Technology in Hotel Service: A Data‐Driven Approach

open access: yesStrategic Change, Volume 34, Issue 4, Page 609-630, July 2025.
ABSTRACT The paper examines personalization‐supporting technologies (PST) in hotel service, differentiating between high‐touch (personal) and high‐tech (digital) technologies. It reveals that in the sampled hotel industry, high‐touch technologies are the preferred choice.

Continental Patterns of Phenotypic Variation Along Replicated Urban Gradients: A Mega‐Analysis

open access: yesEcology Letters, Volume 28, Issue 7, July 2025.
Using a mega‐analysis approach with long‐term data from 21 urban and nonurban great and blue tit populations, we introduce and test hypotheses to determine how urbanisation affects tarsus length and lay date variation at different population levels. We find that urbanisation is associated with increases in phenotypic variation within subpopulations by ...

Synthesis of 16‐Electron RuHCl(CO)(PPh3)2 Catalyst Rendering Superior C═C Double Bond Isomerization Activity

open access: yesChemCatChem, Volume 17, Issue 11, June 6, 2025.
Coordinatively unsaturated ruthenium(II) hydride complex, RuHCl(CO)(PPh3), has been synthetized showing high efficiency in C═C isomerization of terminal alkenes at room temperature and low catalyst loadings. The double bond isomerization of alfa olefins plays a key role in converting plastic waste into propylene via isomerization metathesis (ISOMET ...

Birdsong as an Indicator of Habitat Structure and Quality

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
We investigated the relationship between song traits of the collared flycatcher (Ficedula albicollis) and habitat structure and quality. We found that collared flycatcher males sing at lower frequencies when the canopy is more closed, which may be an adaptive plastic response to the acoustic properties of their environment, or in this way they can ...

On Illyrian component of population in southeastern part of lower pannonia according to contemporary research

open access: yes, 2002
Following the Symposium on distribution of the Illyrians (4th to 2nd centuries B.C., Sarajevo, 1964), the view that the northern border of the Illyrians ran along the line even much southerner than the Sava (nn.2-8) has been firmly established in our archeology; this attitude has been extended to the Illyrian tribes in Roman times (n.7).
