What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

Some examples of research questions include: What framework of circular strategies should local practitioners use? How should practitioners organize their monitoring of the circular economy activities in the region of interest? What are the main products that have the most circular potential in the…

Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.

Phospholipase A/acyltransferase 3 (PLAAT3) and PLAAT4 are enzymes involved in the synthesis of bioactive lipids. Despite sequential and structural similarities, the two enzymes differ in activity and specificity.

This thesis describes biochemical investigations of glucocerebrosidase (GBA), the lysosomal β- glucosidase that is deficient in Gaucher disease (GD).

What are the global relationships between environmental conditions and abundance of distinct types of mycorrhizal fungi in soil and plant roots?

This thesis describes the structural and biochemical characterization of the β-lactamase BlaC from Mycobacterium tuberculosis (Mtb), and the Alr and YlmE proteins from Streptomyces coelicolor A3(2).Mtb is the main cause of tuberculosis.

The aims of the project are to: further clarify 'inhibition by safety'; explore and describe all possible sagety factors, with a special focus on the primary human safety source: social connectedness; reviewing prolonged stress responses without stressors.

Taking as a point of departure the Italian American community in Boston and its process of collective remembrance surrounding Saint Anthony’s Feast, we addressing the limits and potential of montage.

There is accumulating evidence for an increase in severe global drought events. In particular, Europe experienced several severe droughts in 2003, 2015, and 2018 (unprecedented in the past 2,110 years). Such droughts have caused serious and far-reaching impacts on terrestrial ecosystems.

Bacteriophages, or phages for short, are the most abundant biological entity in nature. They shape bacterial communities and are a major driving force in bacterial evolution.

Model based approaches, integrating physiological parameters or linking exposure with response, are powerful tools to quantify and evaluate the impact of genetic differences that are reflected as variability of drug exposure and/or clinical response(s).

The aim is to discover where differently shaped metal nanoparticles distributes in Danio rerio, linking the distribution with genomic responses and so come up with a Mode of Action.

Tin electrodeposition applications have rapidly evolved in the past 25 years.

Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…

In the current global context, there is a pressing need to address sustainable energy supplies to safeguard our Planet and its ecosystems. The choices made by human society have a significant impact on genetic evolution and climate.

The experiences of ethnic ‘Other’ females have – until recently – been widely overlooked in the study of sport. There continues to be a need to produce critical scholarship about ethnic 'Other' girls and women in sport and physical culture, in order to represent their complex, multifarious and dynamic…
