<<The>> role of intrinsic and extrinsic signals in the regulation of brest cancer stem cell activity
(2015-12-18)Il carcinoma mammario rappresenta la neoplasia a maggiore incidenza nel sesso femminile. Nonostante i numerosi progressi da un punto di vista diagnostico e terapeutico, metastasi e recidiva tumorale rappresentano ancora ... -
High-repeatable data acquisition systems for pulsed power converts in particle accelerator structures
(2016-11-02)In this Ph.D. thesis, the issues related to the metrological characterization of high-performance pulsed power converters are addressed. Initially, a background and a state of the art on the measurement systems needed ... -
Survey, diagnosis and monitoring of structures and land using geomatics techniques: theoretical and experimental aspects
(2016-02-11)The Geomatics techniques for the detection and representation of the land and objects have seen an exceptional development in recent years. The applications are innumerable and range from land planning to geophysics, ... -
Seismic vulnerability assessment of classes of reinforced concrete structures
(2016-02-11)The modern seismic design is based on the concept to meet different performance levels, for each of which the structure should not exceed the predetermined degrees of damage. The analysis of elastic-linear benefit from ... -
<<Ia>> catestatina migliora la risposta Frank-Starling in cuori di ratto normotesi e ipertesi agendo come attivatore fisiologico del pathway trasduzionale ossido nitrico-dipendente
(16-12-2015)The myocardial response to mechanical stretch (Frank-Starling law) is an important physiological cardiac determinant. Modulated by many endogenous substances, it is impaired in the presence of cardiovascular pathologies ... -
<<Il>> ruolo del GPER nelle arterie uterine e mesenteriche in gravidanza
(2015-12-16)Low uteroplacental blood flow has been implicated as a cause of pregnancy hypertension and intrauterine fetal growth retardation. A successful pregnancy outcome requires a sufficient uteroplacental blood flow, which increases ... -
Design and development of membranes for CO2/CH4 separation
(2015-12-16)The objective of this work is to compare different membrane materials and different operation modes for the separation of CO2 from CH4. In this context, the working principles in terms of gas transport properties will ... -
Study of the electronic and structural properties of tin dioxide and armchair graphene nanoribbons
(2016-02-02)This dissertation is focused on the study of the electrical and structural properties of two emerging materials, the tin dioxide (SnO2) and graphene, which have attracted the interest of the semiconductor-device community ... -
