Calcium removal by softening of water affects biofilm formation on PVC, glass and membrane surfaces Universiteit Gent
Literature data on the effect of calcium on biofilm structures induced a preliminary study. The effect of calcium removal by water softening (< 1.0 mg Ca2+.L-1) under real-world drinking water conditions on biofilm formation was studied in a pilot plant with reverse osmosis (RO) membranes and in a laboratory-scale biofilm production unit (BPU) with plasticized polyvinyl chloride (PVC-P) and glass as substratum. The results showed a halving of ...
A multiomics integrative analysis of color de-synchronization with softening of 'Hass' avocado fruit: A first insight into a complex physiological disorder KU Leuven
Exocarp color de-synchronization with softening of 'Hass' avocado is a relevant recurrent problem for the avocado supply chain. This study aimed to unravel the mechanisms driving this de-synchronization integrating omics datasets from avocado exocarp of different storage conditions and color phenotypes. In addition, we propose potential biomarkers to predict color synchronized/de-synchronized fruit. Integration of transcriptomics, proteomics and ...
Bean softening during hydrothermal processing is greatly limited by pectin solubilization rather than protein denaturation or starch gelatinization KU Leuven
The rate liming step of bean softening during cooking was evaluated. Red kidney beans (fresh/non-aged and aged) were cooked at different temperatures (70-95 °C) and their texture evolution established. Softening of beans (loss of hard texture) with cooking and increasing cooking temperature was evident at ≥ 80 °C more so for non-aged than aged beans, evidencing hard-to-cook development during storage. Beans at each cooking time and temperature ...
Comparative evaluation of an advanced electrocoagulation treatment system versus a conventional lime softening treatment for removing Ca2+, SO42−, and Mn in groundwater Universiteit Gent
This research aims to evaluate the feasibility of a laboratory-scale batch electrocoagulation system for removing hardness, SO42−, and manganese from groundwater in San Cristobal, a rural community in the Austro region of Ecuador. The efficiency of the electrocoagulation process was compared to the conventional chemical precipitation with lime and alum coagulation. Various variables were analyzed to evaluate the performance of the ...
Thermo-mechanical modelling of UD composites to investigate self-heating and thermal softening effect of polymer matrix Universiteit Gent
The mechanical performance of Fibre-Reinforced Polymer Composites (FRPC) relies highly on the nonlinear thermomechanical behaviour of the polymer matrix with rate- and temperature-dependency. In particular, high strain rate loading can increase the temperature due to self-heating. In this work, a fully coupled thermomechanical FEM-based framework is developed. A constitutive material model is developed to accurately capture the polymer matrix ...
FEM prediction of self-heating and thermal softening in semicrystalline polymers using a unified two-phase intermolecular resistance constitutive model Universiteit Gent
The constitutive modelling of semi-crystalline polymers (SCPs) has to consider several aspects as rate- and temperature- dependencies, self-heating, and in particular, the double yield (DY) phenomenon. Full characterization of all these complex features involves huge efforts in terms of material parameter identification. The contribution of the crystalline phase plays an important role in the evolution of the plastic yield in the SCPs. In this ...
Hardening and softening of multilateral climate governance towards the Paris Agreement Vrije Universiteit Brussel
This article assesses the evolving ‘stringency’ of multilateral climate mitigation governance towards the 2015 Paris Agreement. To do so, we systematically distinguish four key dimensions of hard/soft governance: (1) formal legal status; (2) the nature of the obligations (procedural-substantive); (3) prescriptiveness and precision; and (4) implementation review and response. We find that the governance approach of the Paris Agreement is ...
