ABSTRACT

The present Covid-19 emergency has dramatically increased the demand for pharmaceutical containers and the amounts of related waste. This paper aims at present-ing the upcycling of discarded pharmaceutical glass into various porous ceramics, starting from the activation of fine powders suspended in weakly alkaline solutions (2.5 M NaOH/KOH). The alkaline attack determines the gelation of glass suspen-sions, according to hydration of glass surfaces, followed by condensation starting from 40°C (‘cold consolidation’). Alkali are mostly expelled from the gel, according to the formation of water-soluble hydrated carbonates. The mutual binding of activated powders was exploited for the encapsulation of waste-derived glass (from the plasma processing of municipal solid waste) and quartz sand as coarse aggre-gate. Moreover, industrial mud could be used instead of water in the preparation of alkaline solutions. Depending on the formulations, products comparable to facing bricks can be obtained directly after cold consolidation or after application of low temperature (700°C) firing. In addition, selected formulations led to highly porous glass foams, to be used for thermal and acoustic insulation. © 2022, Cisa Publisher - Eurowaste Srl. All rights reserved.

ABSTRACT

The rapid spread of COVID-19 has highlighted the need for rapid and digital monitoring means for managing information relating to the spread of the virus. The researchers have produced some innovative experiments in this sense, using geomatics technologies and technologies for the treatment of Big Data. In this research, we used an integrated platform (still under experimentation and validation) that allows the treatment of Big Data to obtain forecast models that can be viewed in a GIS. The advantages of the proposed methodology are the ability to use and correlate a lot of data together through a single platform and view the results on a WebGIS platform. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

Accelerated by the COVID-19 pandemic, global digital transformation plays an important role in the green transition. Effective coordination between green and digital transitions is therefore currently considered to be crucial for the European recovery. Specifically, with the advent of Smart Cities, the transposition and consultation of large amounts of data on digital media, the creation of new methods of interaction with places of interest and services, through the use of apps and digital platforms, considerably reduces emissions and climate impact, thus promoting the green transition. In this context, the aim of this research is to help clarify (for cultural heritage and tourism) how these major changes in global systems can shape these transitions and positively influence people and places, in particular by helping to break down territorial inequalities and the phenomena of social exclusion, useful objectives in the strategy of the European Green Deal (EGD). © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

The novel coronavirus disease 2019 (COVID-19) is a truly wicked problem which has remained a stubborn issue plaguing multiple countries worldwide. The continuously increasing number of infections and deaths has driven several countries to implement control and response strategies including community lockdowns, physical distancing, and travel bans with different levels of success. However, a disease outbreak and the corresponding policies can cause disastrous economic consequences due to business closures and risk minimization behaviors. This paper develops a system dynamics framework of a disease outbreak system covering various policies to evaluate their effectiveness in mitigating transmission and the resulting economic burden. The system dynamics modeling approach captures the relationships, feedbacks, and delays in such a system, revealing meaningful insights on the dynamics of several response strategies. © 2021, The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd. part of Springer Nature.

ABSTRACT

RESUMEN Objetivo Describir las características clínico-epidemiológicas y el análisis del tiempo de sobrevida en fallecidos por COVID-19 que fueron atendidos en establecimientos de la Red Sabogal-Callao, en 2020. Materiales y métodos Estudio observacional, descriptivo y retrospectivo en un grupo de 23 pacientes fallecidos por COVID-19, desde el inicio del estado de emergencia (11 de marzo de 2020) hasta el 15 de abril en dos hospitales de la Red Sabogal en el Callao. Los datos fueron analizados en el software estadístico Stata(R) edición 16.0. El tiempo de sobrevida se evaluó con el análisis de Kaplan Meier, log-rank, con un nivel de confianza del 95 %. Resultados Las características epidemiológicas predominantes fueron sexo masculino, edad de 60 a 79 años y comorbilidades (hipertensión arterial y obesidad). Los principales signos y síntomas al ingreso hospitalario fueron disnea, fiebre, tos y frecuencia respiratoria aumentada. Los exámenes de laboratorio mostraron alteraciones: PaFi <300, leucocitosis, linfopenia y lactato aumentado. Entre los informes radiológicos revisados predominan el patrón de vidrio esmerilado y el compromiso pulmonar bilateral. Durante la estancia hospitalaria, el 60,87 % de los pacientes fueron atendidos en la Unidad de Cuidados Intensivos (UCI) y el 69,57 % estuvieron en ventilación mecánica. El 39,13 % recibieron un esquema terapéutico de hidroxicloroquina más azitromicina y en el 39,13 % agregaron corticoides al tratamiento mencionado. Los pacientes fallecieron antes de los 20 días de hospitalización, al día cinco la probabilidad de sobrevida general fue del 43,48 %;la probabilidad de sobrevida fue mayor en quienes estuvieron en ventilación mecánica, aunque sin significancia estadística (p = 0,17). Conclusiones Los pacientes fallecidos fueron, principalmente, adultos mayores de sexo masculino con enfermedades preexistentes como hipertensión arterial y obesidad y clasificados con infección COVID-19 moderada a severa al ingreso hospitalario. El mayor tiempo de sobrevida se observó entre los que estuvieron en ventilación mecánica. ABSTRACT Objective To describe the clinical-epidemiological characteristics and the survival time of deceased COVID-19 patients treated at hospitals belonging to Red Sabogal-Callao in 2020. Materials and methods An observational, descriptive and retrospective study conducted in a population of 23 patients who died of COVID-19 from the beginning of the state of emergency (March 11, 2020) to April 15 at two hospitals belonging to Red Sabogal-Callao. The data was analyzed using the Stata Statistical Software: Release 16. The survival time was assessed by means of the Kaplan-Meier survival analysis and the log-rank test, with a 95 % confidence interval. Results The predominant epidemiological characteristics were male sex, 60 to 79 years of age and comorbidities (hypertension and obesity). The main signs and symptoms at hospital admission were dyspnea, fever, cough and increased respiratory rate. Laboratory tests showed abnormal values: PaO₂/FiO₂ratio <300, leukocytosis, lymphopenia and increased lactate levels. Ground-glass opacities with bilateral pulmonary involvement prevailed in the radiological reports. During the hospital stay, 60.87 % of the patients were treated in the Intensive Care Unit (ICU), 69.57 % were on mechanical ventilation, 39.13 % received a therapeutic scheme consisting of hydroxychloroquine plus azithromycin, and 39.13 % received corticosteroids additionally to the aforementioned treatment. The patients died before reaching 20 days of hospital stay;on day five, the general survival probability was 43.48 %;and the survival probability was higher, although without statistical significance (p = 0.17), in those on mechanical ventilation. Conclusions Deceased patients were mainly males, older adults, those with underlying health conditions such as hypertension and obesity, and those classified as having moderate to severe COVID-19 infection at hospital admission. The longest survival time was observed among those on mechanical ventilation.
