Highlights in Teaching Ethical Management Applied in Achieving Economic Sciences
2018
Talking about ethical strategies for teaching economics subjects is in the same time very easy and very difficult. It’s easy because the capacity of these ethical concerns of crossing the strict framework of the disciplines it is absolutely obvious. It is difficult, because the most difficult thing in the world is to talk about something that it is obvious. Moreover, the capacity of being surprises by the Obvious, the ability of questioning where most of the people see only certainty it is the genuine original impulse of philosophizing.
Random vibration mitigation of beams via tuned mass dampers with spring inertia effects
2019
The dynamics of beams equipped with tuned mass dampers is of considerable interest in engineering applications. Here, the purpose is to introduce a comprehensive framework to address the stochastic response of the system under stationary and non-stationary loads, considering inertia effects along the spring of every tuned mass damper applied to the beam. For this, the key step is to show that a tuned mass damper with spring inertia effects can be reverted to an equivalent external support, whose reaction force on the beam depends only on the deflection of the attachment point. On this basis, a generalized function approach provides closed analytical expressions for frequency and impulse res…
Illness Narrative and Self-Help Culture – Self-Help Writing on Age-Related Infertility
2014
Both self-help books and illness narratives are motivated by an impulse to overcome a crisis and, simultaneously, to help others who suffer from similar conditions. In doing so, authors of self-help and illness narratives move in between polar opposites: they have both individual and collective motives, they have a desire to overcome uncertainty and achieve control and they negotiate the authority of experience versus the authority of expertise. This paper has two objectives: (1) It describes the intersections of illness life writing and self-help culture and traces the thematic, cultural and historical similarities. (2) It analyzes a selection of four autobiographical, U.S.-American self-h…
Optical multichannel monitoring of skin blood pulsations for cardiovascular assessment
2004
Time resolved detection and analysis of the skin back-scattered optical signals (reflection photoplethysmography or PPG) provide rich information on skin blood volume pulsations and can serve for cardiovascular assessment. The multichannel PPG concept has been developed and clinically verified in this work. Simultaneous data flow from several body locations allows to study the heartbeat pulse wave propagation in real time and to evaluate the vascular resistance. Portable two- and four-channel PPG monitoring devices and special software have been designed for real-time data acquisition and processing. The multi-channel devices were successfully applied for cardiovascular fitness tests and fo…

Pulsatile and steady 24-h blood pressure components as determinants of left ventricular mass in young and middle-aged essential hypertensives
2003
In order to explore the relations between left ventricularmass (LVM) and the pulsatile (pulse pressure) andsteady (mean pressure) components of the bloodpressure (BP) curve, 304 young and middle-agedessential hypertensive patients were studied by meansof 24-h ambulatory BP monitoring and echocardio-graphy. In the overall study population, both the BPcomponents showed significant correlations with LVM.These correlations were unevenly distributed in thesubgroups of subjects younger and in those older than50 years. While in this latter subgroup, in multivariateanalysis, both 24-h mean BP (24-MBP) (b¼0.27;P¼0.008) and 24-h pulse pressure (24-h PP) (b¼0.23;P¼0.02) were associated with LVM, in th…

Blood Pressure Measurement Before and After Intervention
2016
The complexity and the uncertainties about long-term effect of the invasive interventions to treat essential hypertension (HTN) require a precise diagnosis about the real “resistance” to the antihypertensive treatment given, and it is defined when a therapeutic strategy that includes appropriate lifestyle measures plus a diuretic and two other antihypertensive drugs belonging to different classes at adequate doses fails to lower systolic blood pressure (SBP) and diastolic blood pressure (DBP) values to <140 and 90 mmHg, respectively. Consequently, in the process of diagnosis and follow-up, blood pressure (BP) measurement is the first step that is not exempt of difficulties due to the variab…
Arterial Stiffness: Effects of Anticancer Drugs Used for Breast Cancer Women
2021
Purpose: It is well known that anticancer drugs used for treating breast cancer can cause cardiac toxicity, and less is known about vascular toxicity. The aim of this study was to assess subclinical vascular effects of anthracyclines and trastuzumab (TRZ) in women treated for breast cancer.Methods: We enrolled 133 female patients with breast cancer undergoing adjuvant treatment with anthracycline-containing chemotherapy (CT) followed by taxane (paclitaxel/docetaxel) + TRZ. Patients underwent a standard echocardiography including measurement of left ventricular ejection fraction and global longitudinal strain at baseline and at follow-up. Vascular toxicity was evaluated by measuring brachial…
