PLANETS AROUND LOW-MASS STARS AND STELLAR ACTIVITY EFFECTS

In the last years the field of exoplanet research has focused its interest in M dwarfs. These stars have became the favourite targets in radial velocity surveys, specially when looking for small planets in the habitable zones of their parent stars. Not only for being the M dwarfs the most common objects in our Galaxy also because the Doppler signals due to small planets orbiting around them are larger and more easily detectable than those around FGK stars. However, stellar magnetic activity and rotation affect the measured radial velocities as surface inhomogeneities rotating with the stellar surface can cause periodic changes in the spectral line centroid. Disentangle these stellar activit…

Effect of indoor nitrogen dioxide on lung function in urban environment

2015

BACKGROUND: High levels of indoor NO2 are associated with increased asthma symptoms and decreased expiratory peak flows in children. We investigated the association of exposure to domestic indoor NO2, objectively measured in winter and spring, with respiratory symptoms and lung function in a sample of adolescents from a southern Mediterranean area. METHODS: From a large school population sample (n=2150) participating in an epidemiological survey in the urban area of the City of Palermo (southern Italy), a sub-sample of 303 adolescents was selected which furnished an enriched sample for cases of current asthma. All subjects were evaluated by a health questionnaire, skin prick tests and spiro…

Is quality of life different between diabetic and non-diabetic people? The importance of cardiovascular risks.

2017

BackgroundTo analyse and compare the impact of cardiovascular risk factors and disease on health-related quality of life (HRQoL) in people with and without diabetes living in the community.MethodsWe used data of 1,905 people with diabetes and 19,031 people without diabetes from the last Spanish National Health Survey (years 2011 +/- 2012). The HRQoL instrument used was the EuroQol 5D-5L, based on time trade-off scores. Matching methods were used to assess any differences in the HRQoL in people with and without diabetes with the same characteristics (age, gender, education level, and healthy lifestyle), according to cardiovascular risk factors and diseases. Disparities were also analysed for…

Ischemic cardiovascular disease in workers occupationally exposed to urban air pollution – A systematic review

2018

Introduction Cardiovascular disease is the first cause of morbidity and mortality worldwide. Among several known risk factors, researchers also focus their attention on the chronic exposure to air pollution. There is much evidence that exposure to air pollution, especially to ultrafine particles, can damage the endothelium and can favour cardiovascular diseases in the general population. Occupational exposition could be an additive risk factor for the cardiovascular system. This article presents a scientific review of the linkage between occupational exposure to air pollution and ischemic heart disease. Material and methods A scientific review was undertaken, followed by PRISMA Statements. …

On multiplicities of cocharacters for algebras with superinvolution

2021

Abstract In this paper we deal with finitely generated superalgebras with superinvolution, satisfying a non-trivial identity, whose multiplicities of the cocharacters are bounded by a constant. Along the way, we prove that the codimension sequence of such algebras is polynomially bounded if and only if their colength sequence is bounded by a constant.

Correlation of wood-based components and dewatering properties of waste activated sludge from pulp and paper industry.

2010

Large amounts of wet sludge are produced annually in municipal and industrial wastewater treatment. Already in pulp and paper industry, more than ten million tons of primary sludge, waste activated sludge, and de-inking sludge is generated. Waste activated sludge contains large quantities of bound water, which is difficult to dewater. Low water content would be a matter of high calorific value in incineration but it also has effects on the volume and the quality of the matter to be handled in sludge disposal. In this research waste activated sludges from different pulp and paper mills were chemically characterised and dewatered. Correlations of chemical composition and dewatering properties…

Cardioprotective effects of phytopigments via multiple signaling pathways.

2021

Abstract Background Cardiovascular diseases (CVDs) are among the deadliest non-communicable diseases, and millions of dollars are spent every year to combat CVDs. Unfortunately, the multifactorial etiology of CVDs complicates the development of efficient therapeutics. Interestingly, phytopigments show significant pleiotropic cardioprotective effects both in vitro and in vivo. Purpose This review gives an overview of the cardioprotective effects of phytopigments based on in vitro and in vivo studies as well as clinical trials. Methods A literature-based survey was performed to collect the available data on cardioprotective activities of phytopigments via electronic search engines such as Pub…

Culture, communication and cooperation: the three Cs for a proactive creative city

2009

The network of European Union creative cities is a powerful new configuration of dynamic, innovative and action-oriented cities, able to transform the space using their network of cultural heritage and activities. From a vision in which the more competitive cities are those able to attract the creative class must go to a vision in which the city becomes generates creativity, presents itself as a powerful incubator of economies based on creativity, culture, research and artistic production. The cities will have to invest in the experience economy, strengthening their identity. The Creative City 3.0, therefore, is an active tension, that requires a long-term vision ability, and calls us to ac…

Ethics and Politics of the Built Environment: Gardens of the Anthropocene

2017

This book is a reflection on the role of gardens in our thinking about our environments, and on the role of urban gardening in our acting and for our environments. More generally, it is an exploration of the ethical and political station of individuals in the Anthropocene - this new epoch in which the Earth is being remade by human activity. The book argues that, in the new epoch, urban gardens and gardening are to become 1) conceptual models for reflecting on the human station within the wider workings of things; 2) contexts and practices of stewardship that enable the fulfillment of individual moral obligations against important global challenges - including food security, climate change,…

Virtues for the Anthropocene

2015

The paper discusses some difficulties that life in Anthropocene poses to our ethical thinking. It describes the sort of ethical task that individuals find themselves confronting when dealing with the planetary environmental quandaries that characterise the new epoch. It then asks what, given the situation, would count as environmentally virtuous ways of looking at and going about our lives, and how relevant virtues can be developed. It is argued that the practice of gardening is distinctively conducive to that objective. Finally, some garden virtues that will be of special importance in the Anthropocene, but have so far been largely neglected by environmental ethicists, are listed and descr…
