Wireless ECG and cardiac monitoring systems: State of the art, available commercial devices and useful electronic components

2021

Abstract Wireless ElectroCardioGram (ECG) systems are employed in manifold application fields: tele-monitoring, sport applications, support to ageing people at home, fetal ECG, wearable devices and ambulatory monitoring. The presence of cables often hinders user’s free movements, alongside clinicians’ routine operations. Therefore, wireless ECG systems are desirable. This paper aims at reviewing the solutions described in the literature, besides commercially available devices and electronic components useful to setup laboratory prototypes. Several systems have been developed, different in terms of the adopted technology; when approaching the development of a wireless ECG system, some import…

Crystal structure of bis(cyclohexylammonium) diphenyldioxalatostannate(IV)

2015

In the title salt, (CyNH3)2[Sn(Ph2)(C2O4)2] (Cy is cyclo­hexyl and Ph is phen­yl), the SnPh2 moiety is chelated by two oxalate anions, leading to a cis arrangement within the distorted octa­hedral coordination sphere of the SnIV atom.

The Impact of Internet and Social Media Use on Well-Being

2021

The present research examines the longitudinal average impact of frequency of use of Internet and social networking sites (SNS) on subjective well-being of adolescents in Germany. Based on five-wave panel data that cover a period of nine years, we disentangle between-person and within-person effects of media use on depressive symptomatology and life satisfaction as indicators of subjective well-being. Additionally, we control for confounders such as TV use, self-esteem, and satisfaction with friends. We found that frequency of Internet use in general and use of SNS in particular is not substantially related subjective well-being. The explanatory power of general Internet use or SNS use to p…

Problematic internet use prior to and during the COVID-19 pandemic

2021

The health and socio-economic challenges arising from the COVID-19 pandemic have led to greater reliance on the internet to meet basic needs and responsibilities. Greater engagement in online activities may have negative mental and physical health consequences for some vulnerable individuals, particularly under mandatory self-isolation or ‘lockdown’ conditions. The present study investigated whether changes in levels of involvement in online activities during the COVID-19 pandemic (i.e., watching TV series,online sexual activities, video games, social networks, gambling, online shopping, and instant messaging) were associated with problematic internet use, as well as whether certain psychol…

An over-the-distance wireless battery charger based on RF energy harvesting

2017

An RF powered receiver silicon IC (integrated circuit) for RF energy harvesting is presented as wireless battery charger. This includes an RF-to-DC energy converter specifically designed with a sensitivity of -18.8 dBm and an energy conversion efficiency of ∼45% at 900 MHz with a transmitting power of 0.5 W in free space. Experimental results concerned with remotely battery charging using a complete prototype working in realistic scenarios will be shown.

Impacto de la formación educativa de los enfermeros sobre la comunicación, la inteligencia emocional y la empatía

2019

ABSTRACT Objective: To determine the influence of nurse education and training on attitudes towards communication, emotional intelligence, and empathy. Method: A cross-sectional study was conducted using three separate instruments to measure attitudes towards communication, empathy, and emotional intelligence, and two questions to determine the academic qualifications of the study participants. The effect of the variables was tested using one-way ANOVA, Pearson correlations, and hierarchical multiple linear regression. Results: The study sample comprised 438 nurses from hospitals in Valencia, Spain. Differences in subscale scores of the instruments according to degree level and specialized …

Dicyclopentaannelated Hexa-peri-hexabenzocoronenes with a Singlet Biradical Ground State

2021

Abstract Synthesis of two dicyclopentaannelated hexa‐peri‐hexabenzocoronene (PHBC) regioisomers was carried out, using nonplanar oligoaryl precursors with fluorenyl groups: mPHBC 8 with two pentagons in the “meta”‐configuration was obtained as a stable molecule, while its structural isomer with the “para”‐configuration, pPHBC 16, could be generated and characterized only in situ due to its high chemical reactivity. Both PHBCs exhibit low energy gaps, as reflected by UV‐vis‐NIR absorption and electrochemical measurements. They also show open‐shell singlet ground states according to electron paramagnetic resonance (EPR) measurements and density functional theory (DFT) calculations. The use of…

European comission's identity during brexit : a communication strategy change on twitter

2021

The European Union (EU) was founded to promote peace, prosperity and other values between an increasing number of member states (European Commission, 2001). However, Brexit has activated a reputation crisis that reinforces Euroscepticism (Borzel; Risse, 2018). The objective of the study is to identify the differences in the semantic construction and thematic framing of the European Commission during a two-year period, previous to Brexit and after Brexit, on a sample of 4827 tweets posted by the European Commission. Findings show that in the period before Brexit, the EU is presented as an abstract political body, highly informative on major crisis, and reactively framing messages with values…
