Metro Manila’s Challenges: Flooding, Housing and Mobility
2014
Among the many challenges faced by MetroManila, the National Capital Region of the Philippines, three appear as the most pressing issues for the everydaylife of its citizens: housing, flooding and traffic. The rapid increase in population of the metropolitan area had led to a mushrooming of substandard housing and squatting, sometimes in danger areas such as waterways and transport lanes. In a tropical context of heavy monsoon rains and frequent typhoons, riverside slums impeding the flow of water appear as one of the reasons—not the only one—why Manila floods, when at the same time people are placed at high risk. Coupled with a lack of available space throughout the metropolis, the high po…
COVID-19 and globalization
2020
The world is experiencing a major pandemic caused by SARS-CoV-2, the Coronavirus causing COVID-19. This disease first entered the human population in Hubei province, China, in mid-November 2019 and manifested in Wuhan, the largest metropolitan area of Hubei, when a cluster of patients were admitted to hospital with a ‘severe pneumonia of unknown cause’ in early December. Although humanity has survived previous pandemics by infectious agents, the present one is unprecedented in its capacity to take advantage of modern globalization allowing for massive transborder spread at a surprising speed. When writing these lines, the pandemic affects 181 countries and territories, with around 1,084,000…
An Analysis of the Residential Segregation of Foreigners in the Municipality of Palermo
2021
Ethnic residential segregation in Italy is emerging as a key question, which will be crucial in the definition and implementation of both urban and social policies. This chapter focuses on this phenomenon in the Italian Metropolitan Area of Palermo. We use individual data for all the population residing in the city on 31 December 2011, organised by ethnicity and neighbourhood to describe the spatial distribution and the residential segregation of foreigners in the city, applying many different segregation measures. Results show that the top ten nationalities in Palermo are not uniformly spread across the different parts of the city but tend to cluster in specific areas. The most segregated …
Comparison of mechanical properties and composition of magnetron sputter and plasma enhanced atomic layer deposition aluminum nitride films
2018
A comparative study of mechanical properties and elemental and structural composition was made for aluminum nitride thin films deposited with reactive magnetron sputtering and plasma enhanced atomic layer deposition (PEALD). The sputtered films were deposited on Si (100), Mo (110), and Al (111) oriented substrates to study the effect of substrate texture on film properties. For the PEALD trimethylaluminum–ammonia films, the effects of process parameters, such as temperature, bias voltage, and plasma gas (ammonia versus N2/H2), on the AlN properties were studied. All the AlN films had a nominal thickness of 100 nm. Time-of-flight elastic recoil detection analysis showed the sputtered films t…
Improved calculations of beta decay backgrounds to new physics in liquid xenon detectors
2020
We present high-precision theoretical predictions for the electron energy spectra for the ground-state to ground-state $\beta$ decays of $^{214}$Pb, $^{212}$Pb, and $^{85}$Kr most relevant to the background of liquid xenon dark matter detectors. The effects of nuclear structure on the spectral shapes are taken into account using large-scale shell model calculations. Final spectra also include atomic screening and exchange effects. The impact of nuclear structure effects on the $^{214}$Pb and $^{212}$Pb spectra below $\approx100$ keV, pertinent for several searches for new physics, are found to be comparatively larger than those from the atomic effects alone. We find that the full calculatio…
Vulvar involvement in pediatric Crohnâs disease: a systematic review
2018
Purpose: The aim of the study is to report a systematic review (from 2000 to 2017) of all pediatric cases of vulvar Crohnâs disease (VCD) and to highlight the key-points for a correct diagnosis and management of this rare condition. Methods: An electronic search using the Pubmed/Medline, Scopus, EMBASE, Cochrane database and Google Scholar database was performed according to PRISMA guidelines. Results: Twenty pediatric studies and 22 cases of VCD were included for analysis. All the articles reported a single case, except two articles where two cases, respectively, are described. Clinical vulvar examination showed the following main manifestations: vulvar erythema (9/22 cases, 40.9%), vulv…
Urbs et Civitas: strategies and technologies for the exploitation of “Metropolis South of the third millennium” (CESCAM 2010)
2011
The contribution illustrates a part of the research: "Strategies and Technologies for the valorization of heritage". Objective of the research is to realize new strategies of building recovery and to promote the cultural patrimony local. Le “metropoli del sud del mondo” sono fortemente caratterizzate da significative densità abitative, anche a causa di un incontrollato consumo di suolo e dell’uso improprio del costruito esistente. In Italia, ed in particolare nel centro-sud di questo paese, città come Roma e Napoli e non ultima Palermo presentano forti criticità in termini di degrado edilizio ed ambientale. Il progetto di ricerca sulle “Strategie e tecnologie per la rigenerazione urbana” (t…

Diseño físico-matemático de un espectrómetro óptico
2016
[EN] This work presents the design and construction of a spectrometer made in the laboratory and the development of mathematical models needed to process and analyze the acquired spectrum. For modeling functions it has been used LabVIEW program. The aim is to bring this type of instrumentation to engineering students from both, physical and mathematical point of view. The application has been successfully integrated in the learning strategies of the course Sensores Fisicos, Master Universitario en Sensores Para Aplicaciones Industriales at the Universitat Politecnica de Valencia. As an example, we have characterized different light sources emitting in different regions of the electromagneti…
