Cím: Fluid Flow Model Applied for Environmental Problems at a Combined Sewer Structure
Szerző: ; ;
Dátum: 2021

(2021)
A junction structure of the greatest combined sewers of Budapest (Hungary) was under hydrodynamic and water quality examinations. The selected junction performs an important role in the operation of a combined sewer overflow. ...
Cím: Warm Younger Dryas summers and early late glacial spread of temperate deciduous trees in the Pannonian Basin during the last glacial termination (20-9 kyr cal BP)

This paper focuses on the last glacial termination vegetation and climate reorganization of the Eastern Pannonian Plain via the multi-proxy paleoecological analysis of Kokad mire in Eastern Hungary. Grains size, sediment ...
Cím: Heterogeneity and Anthropogenic Impacts on a Small Lowland Stream
Szerző: ; ; ; ; ; ; ;
Dátum: 2019

During our work, we investigated the physical and chemical variables of a small surface watercourse to investigate how different anthropogenic effects affect its water quality. Along this small watercourse, there are ...
Cím: Trait-based community assembly of epiphytic diatoms in saline astatic ponds: a test of the stress-dominance hypothesis
Szerző: ; ; ; ; ; ; ; ;
Dátum: 2019

The stress dominance hypothesis (SDH) postulates that strong environmental gradients drive trait convergence in communities over limiting similarity. Previous studies, conducted mostly with terrestrial plant communities, ...
Cím: Unfair distributions counted by the generalized Stirling numbers
Szerző: ; ;
Dátum: 2022
Feltöltve: 2023-02-17
(2022)
We investigate the generalized Stirling numbers S(n, k; α, β, γ) introduced by Hsu
and Shiue from a combinatorial point of view. We present a combinatorial interpretation in terms of certain restricted distributions of ...
Cím: Weather-Influenced Water-Crossing Behaviour of Black Kites (Milvus Migrans) During Migration
Szerző: ; ; ; ; ; ; ; ;
Dátum: 2021

(2021)
From 2014 to 2020, 32 black kites from various European countries were tagged with telemetry devices and tracked to study their spatiotemporal behaviour. Eleven birds which crossed the Mediterranean Sea and the Black Sea ...
Cím: On Higher Order Generalized Geometric Polynomials with Shifted Parameters
Szerző: ; ;
Dátum: 2022
Feltöltve: 2023-02-20
(2022)
We study a special class of higher order generalized geometric polynomials. Based on our combinatorial interpretation of labeled barred preferential arrangements, we prove several recursions. We also study the polynomials ...
Cím: On q-Poly-Bernoulli Numbers Arising from Combinatorial Interpretations
Szerző: ;
Dátum: 2021
Feltöltve: 2022-09-09
(2021)
In this paper we present several natural q-analogues of the poly-Bernoulli numbers arising in combinatorial contexts. We also recall some relating analytical results and ask for combinatorial interpretations.
