Development and analysis of ventilation models in Building Energy Simulations

The ventilation systems are responsible for the preservation of indoor air quality in buildings. However, their operation involves energy costs that cannot be neglected. This aspect is often overlooked, and this thesis tries to boost the research on the topic. The activities involved in the thesis project adopt a modelling approach as it allows to simulate the system under different scenarios and rapidly evaluate energy efficiency solutions. The reported works focus on the development and ana...

La vita quotidiana dell'Età del Bronzo attraverso lo studio dei reperti di origine vegetale: due siti del Bronzo Medio del Veneto a confronto

Archaeological domestic contexts represent an important opportunity to obtain information on the use of plants and space by ancient communities. Living spaces are indeed the fundamental place where everyday life takes place and where activities related to the production, storage and consumption of goods are carried out. The aim of this study is to improve knowledge on various aspects of daily life in Bronze Age communities through the study of plant finds recovered from two sites with domesti...

NOVEL EULERIAN APPROACH FOR THE NUMERICAL SIMULATION OF THE PERFORMANCES OF HYDRAULIC MACHINERIES IN SEDIMENTS – LADEN FLOW CONDITIONS AND THE ESTIMATION OF THE EROSION PATTERNS

The sediment management strategy of a hydropower plant is one of the key aspects affecting the plant environmental impact, since both completely interrupting the sediment flow through the plant and letting uncontrolled streams of sediments flow through the power plant can cause counterproductive results in terms of environmental impact and erosion damages respectively. Therefore, over the past decades, different strategies (e.g sluicing, flushing, coatings application…) have been put in place...

Francesco Zugno (1707-1787): da allievo di Giambattista Tiepolo a protagonista della pittura veneta del Settecento.

La ricerca condotta per la tesi di dottorato ha permesso di ricostruire la biografia e l’attività di Francesco Zugno, esponente di spicco della bottega di Giambattista Tiepolo (1696-1770) e protagonista della stagione settecentesca della pittura veneta. L’obiettivo della ricerca è stato quello, dunque, di ricostruire il profilo di Francesco Zugno, operazione che non poteva prescindere dalla redazione di un catalogo ragionato delle opere realizzate dal pittore in modo da ripercorrere tutta la ...

Development of Innovative Design Strategies for the Optimization of the Performances at Partial Loads of Reversible Pump Turbines

Pump-turbines are essential components in pumped-hydro power plants, frequently switching between pumping and generating modes for grid balancing. These machines are often required to operate under deep partial load conditions, which can compromise both their operability and lifespan. Depending on their specific speed, pump-turbines may exhibit an "S-shaped" discharge-speed and torque-speed characteristic curve during generating mode, leading to instability, increased structural vibrations, a...

Geoarchaeology of Domestic Spaces: Formation Processes and Daily Life in the Bronze Age

This PhD research is conducted within the framework of the ERC Consolidator 2020 project “GEOarchaeology of DAily Practices: Extracting Bronze Age lifeways from the domestic stratigraphic record” (GEODAP - project n. 101001839), led by prof. Cristiano Nicosia (Department of Geosciences, University of Padova). The project aims to reconstruct the daily life of Bronze Age communities by focusing on domestic structures, treating dwellings and their related stratifications as archives preserving e...

Investigation of compressors and dual-source heat pumps working with natural refrigerants

This thesis focuses on the investigation of the performance different types of compressors and the study of dual-source heat pumps using natural refrigerants. Compressor efficiency is a crucial factor in improving system performance and is influenced by the operating conditions. Therefore, experimental studies were conducted on three different compressors. The first was a rotary compressor using CO₂ as refrigerant, where the effects of compressor speed, high pressure, and evaporation tempera...

Terapia di mantenimento della glomerulonefrite lupica con micofenolato mofetile: risultati di uno studio condotto su 70 pazienti

Coinvolgimento del sistema peptidergico centrale nocicettina/orfanina FQ, N/OFQ al recettore NOP nella modulazione del dolore e nei disturbi dell'umore: ansia e depressione

La Nocicettina/Orfanina FQ (N/OFQ) è un peptide endogeno non oppioide agonista dei recettori ORL1, attualmente chiamati recettori NOP. N/OFQ e il NOP sono altamente espressi nel sistema nervoso centrale (SNC), in particolare nelle strutture coinvolte nei processi emozionali (ponte, corteccia frontale). La Nocicettina è coinvolta in molti sistemi e funzioni biologici integrati a livello periferico, spinale e sopraspinale; nel SNC, questo peptide ha infatti un'importante influenza sulla rispost...
