Experimental Investigation on Stiffness and Strength of Single-Lap Z-Pinned Joints in a Laminated CFRP Stress-Ribbon Strip

2016

Carbon fiber-reinforced polymer (carbon-polymer) is an advanced lightweight composite material with high strength and excellent resistance to corrosion and fatigue. Over the past decades, application of fiber-reinforced polymers has been spread from the aerospace to other branches of industry such as automobile and civil engineering. Unidirectional carbon-polymers have a high potential for replacing steel in tensile members. Recently, the first carbonpolymer stress-ribbon bridge has been constructed in Germany. The non-laminated strip-loop carbon-polymer thin strips were used as the load bearing components in this bridge. In comparison with the laminated components, the applied cables are c…

Stranding patterns of the striped dolphin (Stenella coeruleoalba, Meyen 1833, Delphinidae) along the Sicilian coast (Mediterranean Sea)

2019

Along the coasts of Sicily, 73 striped dolphins strandings were recorded from 2013 to 2016. The specimens were collected at the Centro di Monitoraggio e Controllo per Tartarughe marine e Cetacei [Monitoring and Control Centre for Marine Turtles and Cetaceans] at the Istituto Zooprofilattico Sperimentale della Sicilia. Subsequent necropsies were performed to determine the cause of death. The date and stranding location were recorded for each specimen. Total body length, weight, sex, and other key biometric measurements were also recorded for fresh and moderately decomposed specimens. The individuals were divided into three life stage categories on the basis of total body length: (1) newborns…

COMMUNITY DETECTION IN TRIPARTITE NETWORKS OF UNIVERSITY STUDENT MOBILITY FLOWS

2021

The purpose of this study is to explore how the multimode network approach can be used to analyse network patterns derived from student mobility flows. We define a tripartite network based on a three-mode data structure, consisting of Italian provinces of residence, universities and fields of study, with student exchanges representing the links between them. A comparison of algorithms for detecting communities from tripartite networks based on modularity optimization is provided, revealing relevant information about the phenomenon under analysis over time. The findings are applied to a real dataset containing micro-level longitudinal information on Italian university students’ careers.

Optical study of gallium and nitrogen polarity layers of GaN grown on sapphire

2003

A confocal Raman spectroscopic study was carried out on either side of an intentionally grown GaN inversion domain boundary between a pair of strips with opposite (Ga- or N-) polarity. It is shown that the Raman spectra on the N-polarity side displays an A1(TO) mode, prohibited by symmetry considerations, meanwhile on Ga-polarity material this peak is absent, indicating a lower density of defects present in this region. The Raman spectra reveal that in the lateral direction, the change in structural quality accross the inversion domain boundary is rather continuous and extends along 4 ± 1 μm.

Customer Perception Driven Product Evolution - Facilitation of Structured Feedback Collection

2016

Competitive environment not only requires effective advertising strategies from the product producers and service providers, but also to do comprehensive and sufficient analysis of their customers to understand their needs and expectations. Successfully involving customers into a product/service co-creation process, companies more likely increase their future revenue. Customer feedback analysis is widely applied in marketing and product development. Among other challenges (e.g. customer engagement, feedback collection, etc.) automation of customer feedback analysis becomes very demanding task and requires advance intelligent tools to understand customers’ product perception and preferences.…

Molecule-like photodynamics of Au102(pMBA)44 nanocluster.

2015

Photophysical properties of a water-soluble cluster Au102(pMBA)44 (pMBA = para-mercaptobenzoic acid) are studied by ultrafast time-resolved mid-IR spectroscopy and density functional theory calculations in order to distinguish between molecular and metallic behavior. In the mid-IR transient absorption studies, visible or near-infrared light is used to electronically excite the sample, and the subsequent relaxation is monitored by studying the transient absorption of a vibrational mode in the ligands. Based on these studies, a complete picture of energy relaxation dynamics is obtained: (1) 0.5-1.5 ps electronic relaxation, (2) 6.8 ps vibrational cooling, (3) intersystem crossing from the low…

Structural Evolution of Atomically Precise Thiolated Bimetallic [Au12+nCu32(SR)30+n]4– (n = 0, 2, 4, 6) Nanoclusters

2014

A series of all-thiol stabilized bimetallic Au-Cu nanoclusters, [Au(12+n)Cu32(SR)(30+n)](4-) (n = 0, 2, 4, 6 and SR = SPhCF3), are successfully synthesized and characterized by X-ray single-crystal analysis and density functional theory (DFT) calculations. Each cluster consists of a Keplerate two-shell Au12@Cu20 core protected by (6 - n) units of Cu2(SR)5 and n units of Cu2Au(SR)6 (n = 0, 2, 4, 6) motifs on its surface. The size and structural evolution of the clusters is atomically controlled by the Au precursors and countercations used in the syntheses. The clusters exhibit similar optical absorption properties that are not dependent on the number of surface Cu2Au(SR)6 units. Although DFT…

Transferencia génica hepática hidrodinámica en modelos de cerdo in vivo y segmento humano ex vivo

2015

Introducción: La terapia génica es una estrategia terapéutica que pretende utilizar ácidos nucleicos como medicamentos para el tratamiento temporal o permanente de patologías hereditarias o adquiridas. En base al vehículo utilizado para entregar el gen, podemos clasificar la terapia génica en dos grupos: la terapia génica viral (vectores virales) y la terapia génica no viral (vectores no virales o ADN desnudo). La terapia no viral resulta menos eficiente pero más segura. La hidrofección (transferencia génica hidrodinámica) ha mostrado un gran potencial, con resultados terapéuticos en ratón. Sin embargo, cuando la hidrofección se ha trasladado a animales de mayor tamaño, el procedimiento ha …

Edición génica del gen SERPINA1 mediante el uso de CRISPR/Cas9 en células sanguíneas de pacientes con déficit de alfa-1 antitripsina

2022

Introducción. El déficit de alfa-1 antitripsina (DAAT) es una enfermedad rara caracterizada por niveles bajos en sangre de una proteína denominada alfa-1 antitripsina (AAT), principal enzima antiproteasa del suero. El DAAT está provocado por mutaciones en el gen SERPINA1, que codifica para la AAT. Las dos mutaciones más frecuentes se denominan Pi*Z y Pi*S, provocando la primera una sintomatología más grave. A la variante normal se le denomina Pi*M. CRISPR/Cas9 es una herramienta de edición génica adaptada del sistema de inmunidad adquirida presente en bacterias y arqueas que consiste en una endonucleasa, Cas9, guiada por una molécula de RNA simple (sgRNA), complementaria al gen diana. Objet…
