Cím: Weak Ascent Sequences and Related Combinatorial Structures
Szerző: ; ;
Dátum: 2023
Feltöltve: 2023-02-14
(2023)
In this paper we introduce weak ascent sequences, a class of number sequences that properly contains ascent sequences. We show how these sequences uniquely encode each of the following objects: permutations avoiding a ...
Cím: Mammal Extinction Facilitated Biome Shift and Human Population Change During the Last Glacial Termination in East-Central Europe
Szerző: ; ; ; ; ; ; ; ; ;
Dátum: 2022

"The study of local extinction times, together with the associated environmental and human population changes in the last glacial termination, provides insights into the causes of mega- and microfauna extinctions. In ...
Cím: Density and Diversity Differences of Contemporary and Subfossil Cladocera Assemblages: A Case Study in an Oxbow Lake
Szerző: ; ; ; ; ; ;
Dátum: 2022

Cladocerans are biological indicators of environmental changes. Their remains provide information on past changes in lake environments. We studied the correspondence between con- temporary Cladocera assemblages and their ...
Cím: Evaluation of the biostimulant effects of two Chlorophyta microalgae on tomato (Solanum lycopersicum)
Szerző: ; ; ;
Dátum: 2022

(2022)
Eukaryotic microalgae from the Chlorophyta division are used in various bio-industries due to their ability to produce high value compounds. Some of these compounds show plant biostimulant properties when applied to plants, ...
Cím: Passive tracer advection in the equatorial Pacific region: statistics, correlations and a model of fractional Brownian motion
Szerző: ; ; ;
Dátum: 2022
Feltöltve: 2023-02-14
(2022)
Evaluating passive tracer advection is a common tool to study flow structures, particularly Lagrangian trajectories ranging from molecular scales up to the atmosphere and oceans. Here we report on numerical experiments in ...
Cím: Fine-Tuning the Aeration Control for Energy-Efficient Operation in a Small Sewage Treatment Plant by Applying Biokinetic Modeling
Szerző:
Dátum: 2022
Feltöltve: 2023-02-14
(2022)
Wastewater treatment is an energy-intensive process for treating liquid-phase pollutants in urban settlements. The aerobic processes of the biological treatment involve a significant air demand. An optimal control strategy ...
Cím: How the morning-afternoon cloudiness asymmetry affects the energy-maximizing azimuth direction of fixed-tilt monofacial solar panels
Szerző: ; ; ; ; ;
Dátum: 2022
Feltöltve: 2023-02-14
(2022)
In the Northern Hemisphere, south is the conventional azimuth direction of fixed-tilt monofacial solar panels, because this orientation may maximize the received light energy. How does the morning-afternoon cloudiness ...
Cím: Sorption of selected pharmaceuticals on river benthic biofilms formed on artificial substrata
Szerző: ; ; ; ; ; ; ; ;
Dátum: 2022

(2022)
The dissolved organic and inorganic contaminants in rivers, lakes and seas are distributed among the aquatic phase, biota, sediments and biofilms formed on different artificial and natural substrata. Since the biofilms ...
Cím: Set partitions and non-crossing partitions with l-neighbors and l-isolated elements
Szerző: ; ;
Dátum: 2022
