Metodi Chemiometrici per la sintesi razionale di Nanowires di ZnO per l'elettronica su Circuiti

2019

I nanowires di ZnO (ZnO NWs) rappresentano uno dei materiali 1D di maggiore interesse per lo sviluppo di sensori e/o trasduttori, date le loro ot time proprietà piezoelettriche e semiconduttive1 . Tuttavia, la sintesi chimica di ZnO NWs ad alto “aspect ratio” da soluzione acquosa a basse temperature stemi elettronici completi. Recentemente abbiamo sviluppato2 un metodo per il controllo razionale della sintesi di nanowires di ZnO (Figura 1) su supporti conduttivi in rame per la realizzazione di nanotrasduttori...

IL SOFTWARE IRRILAB PER GLI IMPIANTI MICROIRRIGUI: VERIFICHE NUMERICHE E SPERIMENTALI

2018

Nell’ambito delle attività di ricerca condotte presso il Dipartimento di Scienze Agrarie, Alimentari e Forestali dell’Università di Palermo è stato di recente messo a punto un nuovo metodo di calcolo ottimale delle ali gocciolanti, usate nella mi-croirrigazione, attualmente patent pending (“Metodo speditivo per il dimensiona-mento di ali gocciolanti in pendenza”, Università deli Studi di Palermo, Ministero dello Sviluppo Economico - Ufficio Italiano Brevetti e Marchi). Il metodo è stato successivamente esteso ai settori microirrigui, di forma rettangolare e comunque inclinati, in un software applicativo, denominato IrriLab. L’obiettivo del lavoro è quello di “testare” il funzionamento del s…

Estudio del papel de la EMT y las vías de control inmunológico en las micrometástasis moleculares detectadas en ganglio centinela de pacientes con ca…

En los últimos años se ha incrementado el uso de técnicas de biología molecular para mejorar el diagnóstico y conocer mejor la etiología del CP (cáncer pulmonar), debido a que la posibilidad de padecerlo ha sido definida como la interrelación entre la exposición a carcinógenos ambientales y la susceptibilidad individual determinada genéticamente (D’Amico et al., 1999). Dicha susceptibilidad genética es la que resulta determinante para entender por qué, siendo el tabaco responsable de más del 90% de los CP en el hombre y del 80% en la mujer, sólo un 11-12% de los fumadores desarrollan un cáncer (Kratz et al., 2012). Sin embargo, comprender qué factores genéticos determinan una mayor propensi…

Manual Projecte Micromón 2021-22

2021

Aquest manual forma part dels materials oficials utilitzats en el marc de la Small World Initiative™ (SWI). SWI és un programa innovador concebut per Jo Handelsman (Universitat de Yale, EUA) el 2012 per motivar els estudiants cap a l’elecció d’un grau en ciències experimentals, al mateix temps que aborda una amenaça per a la salut a escala global: la disponibilitat reduïda d’antibiòtics eficaços. SWI se centra en la idea d’un curs de biologia bàsic basat en el descobriment, en què estudiants de tot el món porten a terme treball de camp i investigació en el laboratori sobre mostres de sòl a la recerca de nous antibiòtics. Dos terços dels antibiòtics disponibles procedeixen de bacteris o fong…

Comparación de las temperaturas de brillo en Banda L proporcionadas por SMOS y Aquarius sobre distintas zonas de la Tierra

2017

En esta Tesis Doctoral se analizan datos procedentes de dos misiones espaciales de observación de la Tierra que han coincidido en el tiempo, SMOS (Soil Moisture Ocean Salinity), de la European Space Agency (ESA) y Aquarius, de la National Aeronautics and Space Administration (NASA). Estas misiones miden la temperatura de brillo de la Tierra en la banda L de microondas, entre otras variables geofísicas. Este trabajo se centra, fundamentalmente, en la comparación de este parámetro proporcionado por ambas misiones. Las diferentes resoluciones espaciales que proporcionan los sensores de ambos satélites hace difícil la comparación y esto ha motivado la aplicación de diferentes técnicas o métodos…

Response of Soil Microbial Communities to Iron-Porphyrin Catalytic Amendments.

2010

Intensive agricultural practices strongly increase CO2 emission from soil. Synthetic metal-porphyrins were shown to significantly decreased CO2 emission from soil due to an in-situ catalysis of oxidative polymerization of soil organic matter. This research aimed to assess the effects of iron-porphyrin (POR) amendments on soil microbial communities in three arable soils under wheat and maize cropping located in Naples, Turin and Piacenza, characterized by different pedological and climatic conditions. Bulk-soil and rhizo-soil were sampled during 4 years and the microbial groups directly involved in organic matter (OM) mineralization and in key processes of the nitrogen cycle were examined. M…

Scientific Opinion addressing the state of the science on risk assessment of plant protection products for in‐soil organisms

2017

Abstract Following a request from EFSA, the Panel on Plant Protection Products and their Residues developed an opinion on the science behind the risk assessment of plant protection products for in‐soil organisms. The current risk assessment scheme is reviewed, taking into account new regulatory frameworks and scientific developments. Proposals are made for specific protection goals for in‐soil organisms being key drivers for relevant ecosystem services in agricultural landscapes such as nutrient cycling, soil structure, pest control and biodiversity. Considering the time‐scales and biological processes related to the dispersal of the majority of in‐soil organisms compared to terrestrial non…

Infective Endocarditis: Preliminary Results of a Cohort Study in the Southern Italian Population.

2020

Background Infective endocarditis (IE) is an uncommon disease with an involved interplay of clinical and surgical team management. We aimed to define diagnosis parameters and delineate in-hospital management in patients with IE admitted in a tertiary hospital of Southern Italian. Materials and methods Fifty-six consecutive patients (42 males, 14 females; age range: 34-85 years) admitted for IE in the Infectious Diseases, Cardiac Surgery, and Cardiology units, between January 2011 and August 2017, were enrolled. Demographic data, mortality, comorbidities, specimen type, microscopy results, special histological staining performed, and antimicrobial therapy were collected and analyzed. Any com…
