Szintetikus fürdővizek makro- és mikroelem tartalmának vizsgálata

International Journal of Engineering and Management Sciences, 2019
Vizsgálataink során szintetikusan előállított fürdővizek mikro- és makroelem tartalmát elemeztük. A Debreceni Egyetem Környezetmérnöki Tanszékén korábban folyó kutatások során széleskörű laboratóriumi vizsgálatokkal sikerült bebizonyítani, hogy a ...

The averaging of nonlocal Hamiltonian structures in Whitham′s method

International Journal of Mathematics and Mathematical Sciences, Volume 30, Issue 7, Page 399-434, 2002., 2002
We consider the m‐phase Whitham′s averaging method and propose the procedure of “averaging” nonlocal Hamiltonian structures. The procedure is based on the existence of a sufficient number of local‐commuting integrals of the system and gives the Poisson bracket of Ferapontov type for Whitham′s system.

A Quantitative Printability Framework for Programmable Assembly of Pre‐Vascular Patterns via Laser‐Induced Forward Transfer

Advanced Healthcare Materials, Volume 15, Issue 8, 23 February 2026.
Laser‐Induced Forward Transfer (LIFT) is presented as a powerful micropatterning tool. An objective printability framework is developed to assess optimal printing parameter combinations. The technology is further explored for its ability to deterministically deposit microdroplets at predefined locations following CAD designs, enabling the patterning of

Air pollution and greenness independently and interactively influence bird communities in an urban neighborhood

Conservation Science and Practice, Volume 7, Issue 10, October 2025.
In this study, we examined relationships between bird community metrics and environmental measures related to vegetation and air pollution within a residential neighborhood at multiple spatial scales. Greenness and air pollution measures independently and interactively influenced the bird community metrics we evaluated.

Non‐Native Bird Populations Respond Differently to Their Environment and Exhibit Shifts in Ecological Niche Limits Across Continents

Diversity and Distributions, Volume 31, Issue 10, October 2025.
ABSTRACT Aim The degree to which species' niches remain stable over space and time–the niche conservatism hypothesis–is critical for predicting species' responses to environmental change. Tests of this hypothesis typically focus on changes in niche centroids and boundaries.

Exploring High‐Charge‐Density Polyelectrolytes as Membrane Component for Solid Contact Ion‐Selective Electrodes

Electroanalysis, Volume 37, Issue 9, September 2025.
Real‐time potential recording of two potassium‐selective electrodes, each with a different ion‐selective membrane (ISM): a traditional four‐component ISM (light green, bottom) and a new, three‐component one where the matrix polymer and lipophilic salt are replaced by a high‐charge‐density polyelectrolyte (PE) ISM (dark green, top). The incorporation of

Ispitivanje sinterovane cink-kalaj-oksidne keramike fotoakustičnom spektroskopijom [PDF]

Hemijska industrija, 2007
Prahovi ZnO i SnO2 pomešani u molamom odnosu 2:1 mehanički su aktivi- rani u planetamim mlinu sa kuglama u intervalu od 10 do 160 minuta. Do- bijene smeše presovane su i izotermski sinterovane na 1300 °C, dva sata. Uzorci su analizirani primenom rendgenostruktume analize, mikrostmktume analize i fotoakustične spektroskopije.
