Attēla kvalitātes ietekme uz acs struktūru izvērtēšanu foto-diagnostikā
2021
Darba mērķis bija izpētīt 18 samazinātas kvalitātes spraugas lampas attēlu, kuros attēloti acu priekšējo daļu struktūras, ietekmi uz 5 profesionāļu atzinumiem. Attēli, kas sadalīti 3 6 attēlu komplektos trim samazināšanas filtriem, izplūdums (1-6), troksnis (7-12) un kontrasts (13-18), tika parādīti datora ekrānā un salīdzināti ar oriģinālajiem attēliem. Rezultāti tika saskaņoti ar īsto attēla diagnozi un novērtēti 3 punktu sistēmā, pareizs atradums: 1 un 0,5 (daļēji) punkti, nepareizs vai nav atrasts: 0 punkti. Tika reģistrēti 53 punkti no 90 (58% pareizi un 41% nepareizi). Rezultāti liecina, ka attēla kvalitātes samazināšana būtiski neietekme…
Problemi attuali della valutazione della ricerca giuridica
2016
The present contribution aims at underlying that the research quality assessment, beyond the debate on the functions of its system, is nowadays - even in the field of legal research - a fundamental tool for related public policies. At the same time, the increasing complexity of the evaluation's systems and methods is taken into account, especially with regard to the peculiarities of research in the legal field. Examples thereof may be found in the relationship between theory and praxis, in the importance of vocational training and, more generally, of didactics, as well as in the international dimension of the legal problems and in the growing tendency to provide researches, including the le…
Rethinking validity in qualitative sport and exercise psychology research: a realist perspective
2019
Over the last two decades, the relativist approach has significantly shaped debates about the quality and rigour of qualitative research in sport and exercise psychology (SEP). In the absence of any published critiques of relativism in SEP, this paper problematises its central claims with a focus on the most recent contribution offered by Smith and McGannon (2018 Smith, B., & McGannon, K. R. (2018). Developing rigor in qualitative research: Problems and opportunities within sport and exercise psychology. International Review of Sport and Exercise Psychology, 11, 101–121. doi: 10.1080/1750984X.2017.1317357[Taylor & Francis Online], [Web of Science ®], , [Google Scholar]. Developing rigor in …
Mineral Reactions in the Geological Underground Induced by H2 and CO2 Injections
2014
Abstract The R&D project H2STORE is part of the German program to reduce environmental pollution by energy production and in saving fossil natural resources. Thereby physico-chemical processes in the CO2-H2 system by organic and inorganic reactions receive increasing attention. In H2STORE siliciclastic reservoirs and their caprocks from 25 well sites in Germany and Austria are investigated by different analytical methods before and after H2/CO2 batch experiments under sample specific reservoir conditions (p, T, XFluid). Mineral dissolution, precipitation and their impact on reservoir quality (poro-perm, fluid pathways) and on the generation of methane by microbial metabolism triggered by CO…
Determination of Changes in the Quality of Surface Water in the River—Reservoir System
2021
Assessing the changing parameters of water quality at different points in the river–reservoir system can help prevent river pollution and implement remedial policies. It is also crucial in modeling water resources. Multivariate statistical analysis is useful for the analysis of changes in surface water quality. It helps to identify indicators that may be responsible for the eutrophication process of a reservoir. Additionally, the analysis of the water quality profile and the water quality index (WQI) is useful in assessing water pollution. These tools can support and verify the results of a multivariate statistical analysis. In this study, changes in water quality parameters of the Turawa r…
Electrical Safety Analysis in the Presence of Resonant Grounding Neutral
2019
The resonant grounding is one of the possible methods of the system neutral grounding for the medium voltage distribution. IEEE standards do define this grounding configuration, but important advantages and drawbacks of the resonant grounding might not be fully known, due to its rather uncommon application in North America. On the other hand, resonant grounding in Europe is imposed by the increased requirements for power quality, especially for medium-voltage (MV) industrial users, imposed to electric utilities by regulatory authorities, with the purpose to protect the interests of users and consumers. Level of the continuity of the service, magnitude and phase of ground-fault currents, mag…
La investigación en enfermería y la revisión por expertos
2008
Con la revisión por expertos una revista intenta garantizar que los artículos publicados tienen calidad. Este artículo pretende analizar el difícil trabajo de evaluación en el ámbito de la enfermería española. Presentamos algunas sugerencias sobre cómo desempeñar esta función, a la vista de datos recogidos de revistas españolas, y así contribuir a la mejora de las publicaciones en enfermería. Se presenta asimismo una encuesta realizada por contacto personal con revistas relevantes con unas recomendaciones puntuales para los profesionales de enfermería. Through peer review a journal tries to guarantee the quality of published articles. This paper intends to analyze the difficult assessment t…
Are subjective outcomes a “missing link” between driving stress and risky driving behaviors of commuters? Assessing the case of a LMIC
2023
Despite the efforts made by different stakeholders, most of Low and Middle-Income Countries (LMICs) continue to systematically report very negative road safety outcomes. In fact, in countries like Colombia, the rate of deaths from traffic crashes has increased in recent years. One of the most affected collectives in this regard -and at the same time one of the least addressed in specialized literature- are driving commuters, which are commonly exposed to several types of threats and stressors configuring an “everyday risk” potentially impairing their health and safety. This study aimed to assess whether there exists an indirect path -mediated by subjective outcomes- linking driving stress a…
Environmental hazard and water quality: the River Platani basin
2007
The River Platani, situated in the western side of Sicily, is one of the greatest rivers of the island. It runs for about 103 Km and the basin extends to about 1,784.9 Km. It rises near Santo Stefano Quisquina (Ag); the river flows to Capo Bianco (Ag) ends in the Mediterranean Sea. The morphology of the basin is predominantly characterized by rises of modest entities with slopes sweet or calanques. In the containing gypsum and carbonatic stony heaps are diffused the karst phenomena. In the Platani basin some mines are located of rock salt and potassium salts; today the mines are closed after a long activity and they interact with the geomorphology of the territory and on the water quality o…
A sustainable city environment through child safety and mobility:A challenge based on ITS?
2012
Our cities should be designed to accommodate everybody, including children. We will not move toward a more sustainable society unless we accept that children are people with transportation needs, and ‘bussing’ them around, or providing parental limousine services at all times, will not lead to sustainability. Rather, we will need to make our cities walkable for children, at least those above a certain age. Safety has two main aspects, traffic safety and personal safety (risk of assault). Besides being safe, children will also need an urban environment with reasonable mobility, where they themselves can reach destinations with reasonable effort; else they will still need to be driven. This p…
