Skin Erythema Assessment by an RGB Imaging Device: a Clinical Study
2015
In this study, skin erythema assessment of 90 rosacea patients was estimated by a simple, low-cost RGB imaging device. A new erythema index assessment algorithm is proposed and clinically validated. Comparison with dermatologist’s visual assessment shows high correlation.
A review of hydropower plants in Romania: Distribution, current knowledge, and their effects on fish in headwater streams
2021
Abstract Hydropower is currently experiencing a boom in southeast Europe. For Romania, the number of hydropower plants is estimated to be between 545 and 674, but little has been published about their environmental impact. We provide the first overview of the geographical distribution of hydropower plants in Romania, supplemented by a review of current knowledge about their environmental impact, and present case study evidence on the effects of small hydropower plants on fish in headwater streams of the Carpathian Mountains. We show that 49% of the documented 545 hydropower plants in Romania are located in Natura 2000 or other protected areas, 5% are located in water bodies with ‘very good’…
Radiation Hardness Assurance Through System-Level Testing: Risk Acceptance, Facility Requirements, Test Methodology, and Data Exploitation
2021
International audience; Functional verification schemes at a level different from component-level testing are emerging as a cost-effective tool for those space systems for which the risk associated with a lower level of assurance can be accepted. Despite the promising potential, system-level radiation testing can be applied to the functional verification of systems under restricted intrinsic boundaries. Most of them are related to the use of hadrons as opposed to heavy ions. Hadrons are preferred for the irradiation of any bulky system, in general, because of their deeper penetration capabilities. General guidelines about the test preparation and procedure for a high-level radiation test ar…
Ex-Ante Business Model Evaluation Methods: A Proposal of Improvement and Applicability
2019
[EN] Purpose: The purpose of this paper is to choose the best method for ex ante business model evaluation, improve it and provide a framework to put it into practice. Design/Methodology/Approach: After an in-depth review, we chose the best method for ex ante business model evaluation, improved this method, and applied it to a real case study in which business models had been proposed for a Sustainable Smart District project. Findings: We analysed existing ex ante business model evaluation methods, justifying our choice of the best one. We improved this key question-based method by combining classic management tools and a new, promising procedure. We finally found a strong tool to improve b…
Wearable PPG Sensor Matrix for Cardiovascular Assessment
2014
Wearable biomonitoring systems and smart textiles for healthcare are gaining more importance and significance in the R&D sphere due to their potentials in healthcare and sports. Such biomonitoring systems offer a number of advantages in comparison to the conventional equipment proving mobility of the wearer during a long-term monitoring of vital parameters. There are different options to set up the physiological monitoring using wireless and wearable technologies. One of the scenarios is addressing textiles as a carrier of electronics. Moreover, those differ by their functional applications, registered physiological parameters and technology solutions. Still, the most demanded biomonitoring…
Contributions to risk assessment in the departments of welding mechanical engineering companies
2017
The risk assessment professional should cover every activity and every workstation in an enterprise engineering, considering each component of the production system (the system working), each duty, work equipment and working environment. This represents an extremely complicated and complex problem because of production system that is a powerful polluting technology, especially of the atmosphere and soil. The formation of gas welding process is the result of electrodes burning, fluxes, and development of bath fused metal the welded seam. In welding processes, human operators are exposed to smoke and toxic gases, arising from the welding process, which can be dangerous to health. Many acute i…
Circulating tumor and immune cells for minimally invasive risk stratification of smoldering multiple myeloma
2022
Abstract Purpose: Early intervention in smoldering multiple myeloma (SMM) requires optimal risk stratification to avoid under- and overtreatment. We hypothesized that replacing bone marrow (BM) plasma cells (PC) for circulating tumor cells (CTC), and adding immune biomarkers in peripheral blood (PB) for the identification of patients at risk of progression due to lost immune surveillance, could improve the International Myeloma Working Group 20/2/20 model. Experimental Design: We report the outcomes of 150 patients with SMM enrolled in the iMMunocell study, in which serial assessment of tumor and immune cells in PB was performed every 6 months for a period of 3 years since enrollment. Resul…
Racing with superior and inferior team-members: an experimental test of effort changes in a cycling team sprint
2020
The study purpose was to investigate the effect of ability on effort within a sport-specific conjunctive task. The hypothesis was that, compared to working alone, inferior team members would increa...
Language and Symbolic Play in Toddlers
1997
Language-play relations were examined in 110 18-month-old toddlers by observing their play actions in the Symbolic Play Test and assessing their language skills with the CDI parental report and the Reynell Developmental Language Scales. Significant associations between both language comprehension and production (vocabulary, use of suffixes, utterance length) and play were found when percentage of symbolic play was used as the measure of play competence. The total play score which included both functional-relational toy manipulation and symbolic play was not as strongly associated with the language measures. In both play measures relations were, however, higher between play and language com…
Majority and minority influence, task representation and inductive reasoning
1996
One hundred and fifty-five participants had to solve a set of 2–4–6 like reasoning problems (Wason, 1960), in which they were told which hypothesis a majority (or a minority) proposed, as well as which example was used for the test. In a 2 × 2 design, participants were also told that the problems allowed either one single correct answer or several possible answers. Results show that, when the source is a majority and the problem allows one single answer, most participants adopt the source's hypothesis and use confirmatory testing. On the contrary, it is when the source is a minority and the problem allows several answers that most participants give alternative hypotheses and use disconfirma…
