Importance of the toxicological tests in the application and safety of ozone therapy
2018
Until today, there is not any official registry of the different routes of systemic ozone therapy. With the aim to prove the safety of this therapy, several ways of ozone (O3) applications were evaluated, such as rectal insufflation (RI), major autohemotherapy (M-AHT) and intraperitoneal application (IP). For RI, some toxicological tests were performed such as: acute, sub-chronic, mutagenic (bone marrow chromosomic aberrations and micronucleus), teratogenic and irritation studies (at 40 mg/L and 10 mL during 15 days). For M-AHT, acute toxicological (in rats with 21, 47 and 64 mg/L and a volume of 2 mL with daily evaluation up to 15 days) and mutagenic (chromosomal aberration analysis, micr…
Export market integration in the European Union
2004
This paper examines the degree and recent evolution (1988-2001) of export-price dispersion among European Union countries. It also explores the effect of exchange rates on exportprice dispersion by reviewing the experience of some European countries that participated in the exchange rate stability zone. The results indicate that export-price dispersion across European Union countries was usually lower than across OECD countries. Moreover, although there is little evidence of convergence, this is stronger across European Union countries. Finally, even though price dispersion was often lower across European Union countries where exchange rates have been relatively stable than across countries…
Risks and Crises in Virtual Publicity — Can Publicity Crises Be Prevented by Public Relations in the Cyberspace?
2008
The absolute amount of Internet users is growing dramatically, and the cyberspace has become the privileged domain of counter-publicity. Weblogs have already consolidated their position as a communication channel alongside the traditional established media. Weblogs and the blogosphere also offer a new arena for corporate communication. However, the standing of the blogosphere is different compared to the traditional information exchange relationship between corporate communication and the traditional mass media. This chapter is about the new communication sphere, which implies revision of the traditional schemes of public relations and new ethical guidelines for communication.
The game of rankings in a quality world university space
2019
The objective of this text is to proceed to an analysis of international classifications and their impact on two levels: a) their unexpected public success, and b) their decisive influence on higher education policy and strategy. We argue that defining quality assurance is crucial in order to legitimize choices about evaluation on a political and institutional level. In any case, it seems clear that rankings are a dubious construction but highly legitimized by the public and governments. So, under these circumstances, rankings are here and they will probably stay, together with the financial issues they create. Indeed, rankings are an interesting new global market product which universities…
The Role of the Integrated Public Transport Network for Reducing the Congestion in the City of Palermo
2019
The railway link of Palermo is part of the Palermo – Trapani railway line and it is located in the urban site of Palermo. Works funded by the European Union have been started in 2008 for developing a metropolitan service through the improvement of the infrastructure and of the transport service characteristics. The aim of the paper is the analysis of the capacity of the railway infrastructure in terms of frequency and integration with the public transport service of Palermo. Using the Origin-Destination matrix of the Urban Transport Plan of Palermo, the competition between the private car mode and the public transport mode has been simulated, taking into account the improving of the railway…
Ligand-Length Modification in CsPbBr3 Perovskite Nanocrystals and Bilayers with PbS Quantum Dots for Improved Photodetection Performance
2020
Nanocrystals surface chemistry engineering offers a direct approach to tune charge carrier dynamics in nanocrystals-based photodetectors. For this purpose, we have investigated the effects of altering the surface chemistry of thin films of CsPbBr3 perovskite nanocrystals produced by the doctor blading technique, via solid state ligand-exchange using 3-mercaptopropionic acid (MPA). The electrical and electro-optical properties of photovoltaic and photoconductor devices were improved after the MPA ligand exchange, mainly because of a mobility increase up to 5 ×
Internet Access in Rural Areas: Brake or Stimulus as Post-Covid-19 Opportunity?
2020
The lack of internet access in most rural areas has become a challenge worldwide. The Covid-19 pandemic has highlighted trends such as teleworking and e-commerce, meaning an opportunity for the local economy of these areas, but with serious difficulties in carrying it out. This paper aims to detect this lack of internet in inland areas of the region of Valencia through local actors, in order to identify clear priorities and real needs through an explorative and replicable approach based on agglomerative hierarchical clustering (AHC). The main findings suggest that there are different patterns in the rural internet access related to adequate infrastructure and planned actions by local counci…
Electoral Debates. The Last Stronghold Against Mediatization? A Case Study of the 2015 Spanish General Elections
2018
26 Páginas La mediatización de la política alcanza su máxima expresión con motivo de las campañas electorales, en las que los actores políticos se afanan por lanzar sus mensajes persuasivos al espacio público, con el fin de acceder y, en última instancia, convencer al electorado. Este artículo se propone analizar el discurso político en los debates electorales televisados durante la campaña de las elecciones generales españolas de diciembre de 2015. El objetivo del análisis es observar qué temas destacaron en las intervenciones de los actores políticos y determinar si la mediatización afecta el contenido de los debates electorales, o si, por el contrario, estos espacios se mantienen como fo…
First Measurement of the $Q^2$ Dependence of the Beam-Normal Single Spin Asymmetry for Elastic Scattering off Carbon
2018
We report on the first Q^{2}-dependent measurement of the beam-normal single spin asymmetry A_{n} in the elastic scattering of 570 MeV vertically polarized electrons off ^{12}C. We cover the Q^{2} range between 0.02 and 0.05 GeV^{2}/c^{2} and determine A_{n} at four different Q^{2} values. The experimental results are compared to a theoretical calculation that relates A_{n} to the imaginary part of the two-photon exchange amplitude. The result emphasizes that the Q^{2} behavior of A_{n} given by the ratio of the Compton to charge form factors cannot be treated independently of the target nucleus.
DIVIDEND POLICY AND THE NATURE OF CASH FLOWS OF SELECTED COMPANIES LISTED ON THE FRANKFURT STOCK EXCHANGE
2021
The main purpose of the article was to investigate whether there are joint-stock companies listed on the FSE between 2000-2017 that paid regular dividends. The sample was divided into dividend companies and other companies. A subsidiary objective was to compare the dividend companies and other companies concerning the direction of their cash flows (positive/negative). Based on the conducted research, it should be stated that dividend companies had on average higher DPS than other companies. The conducted research shows that the percentage of dividend companies in variants 1-4 among the models of eight cases based on selected information on cash flows is greater than that of other companies.…
