Murdered women’s children: A social emergency and gloomy reality
2018
Femicide, defined as the killing of females by males because they are females, is be-coming recognized worldwide as an im-portant ongoing manifestation of gender inequality. Actual or imminent separation, abuser’s access to firearms, prior threats with a weapon, prior threats to kill the victim, a stepchild in the household, prob-lematic alcohol and illicit drug use, as well as mental health problems, are associated with a substantially higher risk of femi-cide. Little is known about the number of orphaned children who have instantane-ously lost both parents. Sparse attention has been focused on children whose moth-er was murdered: these are difficult cases for child psychiatry teams. Decis…
Polymers of Limonene Oxide and Carbon Dioxide: Polycarbonates of the Solar Economy
2018
Limonene epoxide (1,2 limonene oxide) readily reacts with carbon dioxide in a ring opening copolymerization reaction with insertion of CO2 and formation of polycarbonates of exceptional chemical and physical properties. Both poly(limonene carbonate) and poly(limonene dicarbonate) can be synthesized using low cost Zn or Al homogeneous catalysts. This study addresses selected relevant questions concerning the technical and economic feasibility of limonene and carbon dioxide polymers en route to the bioeconomy.
EPR investigations of polymeric and H2O2 -modified C3N4 -based photocatalysts
2019
The C3N4 -based nanopowders prepared by thermal condensation of melamine (MCN) with subsequent thermal etching (MCN-TE) and H2O2 -treatment were investigated by Q- and X-band EPR spectroscopy in dark and upon in situ UVA or visible-light exposure. Lorentzian signal at g = 2.003, more pronounced in the case of the thermally etched material, dominates EPR spectra of MCN and MCN-TE. More complex spectra were found for H2O2 -treated photocatalysts revealing the presence of signals attributed to the radicals produced via H2O2 interaction with C/N sites in the C3N4 polymeric network. The X-band spectra monitored upon in situ irradiation of the C3N4 -based photocatalysts evidenced the intensity gr…
Overview on photoreforming of biomass aqueous solutions to generate H2 in the presence of g-C3N4 based materials
2023
Photoreforming (PR) of biomass can be considered a viable technology under mild experimental conditions to produce hydrogen with a high reaction rate using compounds from renewable resources and waste materials. The application of biomass PR gives rise to both hydrogen generation and biomass waste valorization. The process could be scaled up to obtain hydrogen under natural sunlight irradiation, and research on polymeric carbon nitride (g-C3N4)-based photocatalysts has been widely carried out in recent years. The non-metallic-based carbon nitride materials are economical and (photo)stable polymer semiconductors, and their physicochemical surface and electronic properties are optimal for obt…

Visioni dell’America. Viaggio, spazialità e narrazione in De Amicis e Amado
2021
Nella prospettiva della geografia culturale l’odeporica offre l’opportunità di studiare alcune dinamiche di (ri)produzione simbolica relative al modo di concepire e rappresentare concetti chiave quali lo spazio, il paesaggio e le interazioni umane. Questo lavoro, partendo dall’analisi di alcuni brani significativi di due raccolte di scritti, In America (1897) di Edmondo De Amicis e In giro per le Americhe (2001) di Jorge Amado, studia, con un approccio geografico-culturale e semiotico, le modalità di costruzione e descrizione dello spazio fisico e simbolico comprese le «frontiere», nonché le interazioni e la socialità attraverso la testualizzazione di esperienze diverse. La comparazione fra…
La hospitalización domiciliaria: antecedentes, situación actual y perspectivas
2001
Objetivo. Determinar las distintas variantes que ha tenido el concepto de la hospitalización domiciliaria a lo largo del tiempo, para así contribuir al debate sobre las circunstancias que inciden en la gestión sanitaria frente a futuros retos. Métodos. Se revisa la literatura sobre la atención domiciliaria como modalidad asistencial de salud mediante una exploración de las publicaciones indizadas en MEDLINE, LILACS y el Índice Médico Español durante el período de 1995-2000. Resultados. La hospitalización domiciliaria ha tenido un desarrollo desigual a lo largo del tiempo en diferentes países y son varios los modelos de este tipo de atención, cada uno con sus respectivas ventajas y desventaj…

Predictors for Nursing Home Admission and Death among Community-Dwelling People 70 Years and Older Who Receive Domiciliary Care
2015
Original Research Article Aim: The aim of this study was to analyze which variables predicted nursing home admission (NHA) and death. Methods: 1,001 recipients of domiciliary care were assessed three times in a 3-year period. Through bivariate and multivariate Cox proportional hazards regression models, associations between a covariate and the outcomes were analyzed. Results: Participants with dementia had a higher risk of NHA (odds ratio 3.88, 95% confidence interval 2.92-5.16) compared to participants without dementia. The Neuropsychiatric Inventory sub-syndrome psychosis, poorer functional impairment and age were associated with NHA. Female sex, age, worse medical health and functional i…
Photocatalysis: Applications
2016
Heterogeneous photocatalysis is a sustainable technology mainly employed for water and air cleaning purposes. However, in the last two decades a lot of attention has been given to photocatalysis as an alternative route to be used in place of traditional industrial processes. The sustainability of photocatalysis mainly comes from the exploitation of renewable sources, such as solar light, and the possibility to avoid unsafe reagents/solvents and severe temperatures and pressures. In this chapter we give a critical presentation of some case studies concerning the use of heterogeneous photocatalysts, such as modified and bare TiO2, ZnO, ZnS, WO3, titanium silicalite, V2O5, polyoxometalates, Cd…
