Characterization of Spirulina microalgae as a new alternative food source
A reduction in agricultural productivity associated with water scarcity and land degradation, combined with the growing world population and malnutrition highlights the need for new alternative food sources. In this challenging field, Spirulina microalgae emerges as a promising candidate thanks to its high nutritional value and beneficial effect on human …
Development and employment of untargeted and targeted tools for virus detection in the frame of water-based epidemiology
Traditional methods of studying viruses are limited in their ability to detect novel pathogens, but recent advances in high-throughput sequencing (HTS) are changing that. HTS allows researchers to probe deeply into the virome of various hosts and environments, identifying known and unknown viral species. However, a targeted approach, like quantitative …
An intelligent cognitive system for computational psychotherapy with a conversational agent for attitude and behavior change in stress, anxiety and depression
The increasing prevalence of mental health issues worldwide has amplified the significance of computational psychotherapy, which includes creating computational tools for the mental healthcare and tools to support existing mental health professionals. This work presents a computational psychotherapy system that predicts and forecasts mental health issues in users, and utilizes …
Topology-induced phenomena and caloric effects in condensed matter
The first part of the thesis deals with the impact of surface-functionalized nanoparticles (NP) can have on the stability of liquid crystal (LC) phases. Experimental data of NP concentration-driven phase transition between the isotropic and nematic phase in 5OO8 LCs were used to create a minimal mathematical model that would …
The effect of spaceflight associated factors on the eye
The unexplained aetiology of Spaceflight Associated Neuro-ocular Syndrome (SANS) jeopardises all planned future missions to the Moon and Mars. Various intrinsic and extrinsic potential risk factors have been proposed to contribute to its manifestation. Specifically, the present thesis compared the effect of static exercise (simulating the exercise performed by astronauts …
Atomically resolved transmission electron microscopy and in-situ voltage driven dynamic response of domain walls in lead-free ferroelectrics
Ferroelectric domain walls (DWs) are nano-to-atomic-scale interfaces that separate domains of different polar order. What makes DWs so interesting is their dynamic nature in an electric field, which offers an exciting potential for nanoscale and atomic-scale applications, but, also, more generally, the dynamics of DWs is linked to a fundamental …
In silico approach to understanding the mechanism of action and chemical toxicity prediction on human aromatase enzyme
Aromatase is an enzyme member of the cytochrome P450 superfamily coded by the CYP19A1 gene. Its main biological function in humans is the conversion of androgens into estrogens, transforming androstenedione into estrone and testosterone into estradiol. This enzyme is present in several tissues, and it has a key role in …
Use of information and communication technologies, data and knowledge to increase the impact of digital environments on food choice
Food and eating environments play a crucial role in shaping consumers' food choices. As food decision-making shifts more into the digital environment, it is essential to understand the impact of this setting on consumer's dietary behaviours. Online platforms and mobile apps provide great opportunities for the promotion of healthier food …
Surface modifications of cellulose nanomaterials: mechanisms, kinetics and their applications
Synthesized in green plants, cellulose is the most abundant natural biopolymer on the planet and is thus widely available, cheap and renewable. Furthermore, its hierarchical structure allows extraction of nanosized particles in the form of cellulose nanocrystals (CNCs), obtained with hydrolysis or cellulose nanofibrils (CNFs), isolated through chemical, biological pretreatment …
Computational modelling of information dynamics in children’s melody perception
This thesis focuses on the information dynamics of children’s melody and, more specifically, on modeling children’s perception of melodic surface. The topic of children’s melody has not received much attention in the past, and there are currently no clear definitions of what exactly a “children’s melody” is. As neither children’s …
