Effects of a macroscopic fixed charge inhomogeneity on some membrane transport properties

1991

Abstract The effects that a macroscopic fixed charge inhomogeneity exerts on some membrane transport properties have been theoretically analyzed. To this end, we introduce two particular inhomogeneous fixed charge distributions on the basis of previous experimental work, and the transport equations are assumed to be the Nernst-Planck equations. It is found that a macroscopic redistribution of a constant quantity of fixed charge groups can modify the observed transport properties, the two inhomogeneous membranes here considered exhibiting permselectivities different from those of otherwise identical homogeneous membranes. Although the main emphasis of the study is on the basic aspects of tra…

Extracting work from random collisions: A model of a quantum heat engine

2022

We study the statistical distribution of the ergotropy and of the efficiency of a single-qubit battery ad of a single-qubit Otto engine, respectively fuelled by random collisions. The single qubit, our working fluid, is assumed to exchange energy with two reservoirs, a non-equilibrium "hot" reservoir and a zero temperature cold reservoir. The interactions between the qubit and the reservoirs is described in terms of a collision model of open system dynamics. The qubit interacts with the non-equilibrium reservoir (a large ensemble of qudits all prepared in the same pure state) via random unitary collisions and with the cold reservoir (a large ensemble of qubits in their ground state) via a p…

The Feasibility of a Text-Messaging Intervention Promoting Physical Activity in Shift Workers : A Process Evaluation

2023

Workplace health promotion programs (WHPPs) can improve shift workers’ physical activity. The purpose of this paper is to present the process evaluation of a text messaging health promotion intervention for mining shift workers during a 24-day shift cycle. Data collected from intervention participants with a logbook (n = 25) throughout the intervention, exit interviews (n = 7) and online surveys (n = 17) examined the WHPP using the RE-AIM (Reach, Efficacy, Adoption, Implementation and Maintenance) framework. The program reached 66% of workers across three departments, with 15% of participants dropping out. The program showed the potential to be adopted if the recruitment strategies are impr…

Work-life balance: lo stato dell’arte e la sua applicazione nell’emergenza epidemiologica

2020

The essay examines the measures undertaken both at EU and national level to face the needs of work-life balance. More speci&cally, the paper analyzes the main provisions introduced by EU Directive 2019/1158 on the balance between private and professional life, as well as the subsequent Italian regulatory framework with particular reference to the rules carried-out during the epidemiological emergency: the Author highlights how work-life balance policies have effects not only on female employment but also on the distribution of care burdens between men and women and, consequently, on gender equalit

La presa in carico residenziale: percorsi di ricerca nelle comunità per minori.

2012

Le comunità residenziali possono essere concepite come “campi esperienziali”, luoghi di esperienza condivisa all’interno dei quali, nel qui e ora della quotidianità e nell’intreccio di storie, esperienze, culture, visioni del mondo, orientamenti e bisogni diversi, gli “abitanti” della comunità, minori e operatori, intrecciano reti relazionali complesse. L’esplorazione di tali campi esperienziali e del loro funzionamento, la definizione di setting di lavoro clinico e formativo nei quali avviare percorsi trasformativi, è l’interesse che ha mosso il progetto di ricerca e intervento che qui presentiamo. Nella prospettiva della valutazione del lavoro clinico e della qualità dei servizi offerti a…

GENETIC AND ENVIRONMENTAL VARIATION IN PERCEIVED EXERTION AND HEART RATE DURING BICYCLE ERGOMETER WORK

1977

The relative contributions of heredity and environment to the variance in heart rate (HR) and rating of perceived exertion (RPE) during the bicycle ergometer work were studied with 14 pairs of male (6 monozygous (MZ) and 8 dizygous (DZ)) and 22 pairs of female (8 MZ and 14 DZ) twins ranging in age from 11 to 20 years. The results showed for both sexes that no significant differences in the intrapair variances of HR and RPE could be observed between the MZ and DZ twin samples. Thus it was concluded that in contrast to several other parameters of the measurements of the physical work capacity HR and RPE are not influenced to any significant degree by the genetic factors.

Recognition, Work, Treatment

2017

The article I am going to propose is a reflection on the theme of recognition in working and social contexts, and focuses on problems and troubles people cope with in this historical moment. This is a period during which reciprocity and recognition relationships involving our education and work career seem to have no more value, because the world of work now focuses on involving people in production and does not care about involved subjects' life plans. I also wish to point out risks and sufferance affecting subjects who perceive with always greater precision that they are more and more often oppressed by labor and mind exploitation, rather than considered human resources with a working com…

Vulnerability in Migration: The Applicability of European Recommendations, International Reports and Guidelines to the Italian System of Reception an…

2018

The European Parliament’s Report focuses on the integration processes for a particular category of refugees, considered as belonging to “vulnerable groups”, namely women seeking international protection and female refugees. Women seeking international protection or refugees, in fact, are bearers of demands and needs which, in part, are specific to all those people who, often forced to abruptly abandon their countries of origin, seek protection in host countries, bringing with themselves a heavy burden of persecution, war, violence and poverty. The humanitarian response along the routes of the eastern Mediterranean and the western Balkans has set as a priority the introduction of measures to…

Perspectives of health personnel on how to preserve and promote the patients' dignity in a rehabilitation context.

2013

Aims and objectives To explore how healthcare personnel comprehend the term dignity and what they do to attend to, preserve and promote the dignity of patients in the rehabilitation context. Background Literature reveals that knowledge exists concerning the nature of dignity. Literature is scant on how health personnel think the reasons may be when patients do not maintain their dignity or how caregivers might improve and strengthen their concern in preserving and promoting the patients' dignity in a rehabilitation context. Design The study was explorative and descriptive, with content analysis of gathered empirical data. Methods Qualitative focus group interviews with representatives from …
