Improvement of N and P ratio for enhanced biomass productivity and sustainable cultivation of microalgae.

Microalgae cultivation could contribute to the achievement of several sustainable development goals (SDGs). However, cultivating , like any other microalgae, is challenging due to various biotic, abiotic and process related factors that can affect its growth and biomass productivity. Nutrient availability, particularly N and P, and their ratio play a crucial role in building cellular structures and maintaining metabolic processes, determining basically the maximum achievable biomass productivity under given circumstances.

Changes in Plant and Grain Quality of Winter Oat ( L.) Varieties in Response to Silicon and Sulphur Foliar Fertilisation under Abiotic Stress Conditions.

In order to investigate the abiotic stress (drought) tolerance of oat ( L.) with silicon and sulphur foliar fertilisation treatments, and monitor the effect of the treatments on the physiology, production, stress tolerance, plant, and grain quality of winter oat varieties, a field experiment was conducted in the growing season of 2020-2021. As a continuation of our article, published in another Special Issue of Plants, in this publication we evaluate the effect of silicon and sulphur treatments on the quality of winter oats.

Shade tolerance as a key trait in invasion success of submerged macrophyte over .

The synergy between climate change, eutrophication, and biological invasion is threatening for native submerged plants in many ways. The response of submerged plants to these changes is a key factor that determines the outcome of biological invasion. In order to explain the invasion successes, we investigated the combined effects of climate change and eutrophication-related environmental factors (temperature, light, and nutrients) on the trait responses of a native () and an alien () submerged species.

Enstrophy change of the Reynolds-Orr solution in channel flow.

The plane Poiseuille flow is one of the elementary flow configurations. Although its laminar-turbulent transition mechanism has been investigated intensively in the last century, the significant difference in the critical Reynolds number between the experiments and the theory lacks a clear explanation. In this paper, an attempt is made to reduce this gap by analyzing the solution of the Reynolds-Orr equation.

Numerical simulation of an acoustically excited plane jet in an incompressible framework and comparison with experimental data.

This paper is concerned with the interaction of a two-dimensional plane jet with transverse plane acoustic waves, which occur, for example, in flue instruments in the vicinity of the nozzle exit. The acoustic excitation is modeled with fluctuating boundary conditions within the framework of an incompressible simulation. This method can be easily implemented in commercial CFD software.

The Ecophysiological Response of Two Invasive Submerged Plants to Light and Nitrogen.

Two submerged species have small differences in their ecophysiological responses when exposed to individual environmental factors. However, field observations showed that under eutrophic conditions with low light availability, could be displaced by . Here we investigated the combined effect of environmental factors on the ecophysiological response of the two species in order to explain the differences in their invasion successes.
