At an aquaponics farm in Luxembourg called “Fësch Haff” the effect of the water quality on the growth rate and behaviour of the rainbow trout has been analysed. Three times a week the water quality in the fish tank expressed by temperature, KH (carbonate hardness), pH, ammonium/ammonia, nitrite, nitrate …

Designing lead-free piezoelectric ceramics with tailored electrical properties remains a critical challenge for various applications. In this paper we present a novel methodology integrating Machine Learning (ML) and optimization procedures to fine-tune electrical properties in lead-free (1-x) Na0.5 …

This study sought to comprehensively examine the complex relationship between de-icing substances and asphalt pavement, with an emphasis on understanding how freeze-thaw cycles and various deicers affect infrastructure performance and longevity. The primary focus was centered around strengthening understanding …

High level circular use of post-consumer insulating glass units will contribute to lower the environmental and social impact of insulation glass industry. The application of various circular strategies for insulating glass units (IGU’s) is rising. The product age will give an indication of the remaining …

The built environment requires energy-flexible buildings to reduce energy peak loads and to maximize the use of (decentralized) renewable energy sources. The challenge is to arrive at smart control strategies that respond to the increasing variations in both the energy demand as well as the variable …

Species rich grasslands provide ecosystem services such as floral and faunal diversity, livestock forage, carbon sequestration and water regulation. However, the best combinations of sward diversity and management intensity to achieve the above-mentioned ecosystem services are not fully known. To address …

Per-fluoroalkyl and polyfluoroalkyl substances (PFASs) are persistent organic pollutants and do not degrade in the environment. They contain a carbon-fluorine bond, and these are called organic fluorides. A group of PFASs, which can be extracted from soil samples and be analysed, are called extractable …

The long spined sea urchin Diadema antillarum was an abundant grazer on Caribbean coral reefs, until 1983–1984, when densities were reduced by ∼98% during a region wide die-off. Since then, there has been very little natural recovery of the species and interest is growing in applying aquaculture as a …

Floating photovoltaics (FPV) is emerging as a promising renewable energy technology which enables the production of electricity on surface waters. While this technology could potentially make an important contribution to the energy transition, the current uncertainty about the water quality effects of …

Since the start of the COVID-19 pandemic, organisations have drastically started to reformulate the functionalities of their offices. The trend hybrid working has caused office buildings to have considerable low occupancy rates, as employees rather perform certain tasks at home and do not feel like the …
