Invocación y modelo : las nuevas imágenes de la prensa

El estatuto cultural de la fotografía, de carácter esencialmente analógico y referencial en relación a la realidad que toma como punto de partida, fue históricamente legitimado de acuerdo con las condiciones de nacimiento y desarrollo de este medio expresivo. Posteriormente, la prensa de masas afianzó su papel de testimonio de las transformaciones sociales. En la actualidad, no obstante, esa función testimonial de la imagen fotográfica está siendo postergada en favor de su capacidad para generar fascinación y negocio a través de la mera espectacularidad.The cultural statutes of photography, essentially of an analogical and referential nature in relation to reality, which serves as its starting point, was historically legitimised according to the conditions surrounding the birth and development of this medium of expression. Later, the press strengthened its role as providing testimony with regard to social transformations. Nowadays, however, this role of the photographic image is being discarded in favour of its capacity to generate fascination and money by offering images that are merely of a spectacular nature

The long and winding road.

It has been a very long trip since I wrote my last editorial. The first issue of the Journal received a strong welcome from all over the world in the beginning of 2016, but there was something missing that drove us to a winding road that ended in an even stronger situation: the support of the University of Valencia?s Publication Service (UVPS). The missing thing in the first issue was the DOI (Digital Object Identifier). All the online journals have a DOI to identify the papers and allow a permanent link to them. Each DOI is unique for each paper. We look for a DOI provider in our environment and found the UVPS to offer DOIs for free to their teachers. As I am one of them, I went to ask for the requirements and the first one was to have an Open Journal; I emailed the WFOT Board and all agreed to change our journal policy to an Open one. Then, the University offered us to use their Open Journal System (OJS) of edition for free. This was a hard decision to take, because we have spent many hours developing our own free edition system, but the UVPS?s OJS offered something else ? free indexation! So we decided to move the edition process to OJS. It took us ONE YEAR to setup the OJS for our journal and when we finally got it ready, our journal web site (www.jo3t.org) was HACKED. We had then to change our domain name to the current one and use a secure protocol to access the journal (https), modify some security issues and move the contents of the old web site to the new one. Who says that the editorial work is boring? Many papers for issue 2 had been sent using the old editorial manager, so we move them into the new OJS; some authors suffered this migration. Thanks for the patience! Lately, is was impossible to get 10 papers for the second issue in 2017, so we decided to postpone the papers compiled for issue number 2 to issue number 3 and devote this second issue to be the Proceedings of our 5th WFOT Meeting in Mumbai ? India. We upload all the abstracts to the system, that have been peer reviewed and language checked by our language copyeditor. When all this was done, the UVPS updated OJS and included a tool for NLM/Pubmed export that obliged us to re-review the papers for a proper indexation. To finish our trip, we got our desired DOIs for our journal?s papers and we are ready for Pubmed indexing. The papers planned to be published now have been assigned to issue number 3, we want to publish this year in June-July. We have already papers for issues numbers 4 and 5 (2019) so I am happy to say that the Journal of Ozone Therapy is rolling on!!! Again, thanks to every author for their patience. Now we start pushing for Pubmed indexation and have good Impact Factor. We have the tools and the help of the UVPS, but we need you all to get the journal we all need and want

Good prospects

This third issue compiles the papers sent during 2017 and some others sent in 2018, so I apologise all the authors for the delay and thank them for their patience. The 4th issue will be devoted to be the proceeding of the World Congress organized by Dr Lamberto Re in Ancona - Italy in 2017 and will be published by Summer-19. Issue number 5 will be devoted to spine diseases thanks to the wonderful effort done by Dr. Alberto Alexandre from Treviso - Italy. The rest of the papers already sent and new to come will be published on 2020. The indexation of this journal is so fantastic, thanks to the University of Valencia?s Publication Service, that it is quickly compiled in all open journals search indexes. We will be included in other search engines as soon as we fulfil their requirements. By the moment, the only thing we need is papers. This issue has scientific articles devoted to basic investigation, toxicity and security topics, AIDS, cardiology, hepatitis, neurology, odontology and osteoarthritis. All of them are very interesting and try to clarify some basic and clinical aspects of ozone therapy. I want to express my most sincere gratitude to all the reviewers - members of the editorial board - that have collaborated and really helped to increase the quality of all of them. Peer review process is our corner stone in order to publish a good quality journal, as I believe this is. For the readers, I thank them for reading our journal so much and download our papers so many times; you can read in the STATISTIC section (still on testing) the great impact our journal is having in the scientific community. I also encourage them to publish their experience. I know that many of them have never published and are afraid of doing it, but I promise I will help anybody that wants to write a paper to do it. Some of you have already checked this. I wait for your papers meanwhile we prepare the next issues! Prof. Jose Baeza-Noci WFOT Past-President JO3T Editor-in-chie

Traffic Risk in toll motorway concessions in Spain: An analysis of the ramp-up period.

This paper analyzes the behaviour of actual traffic versus the traffic declared by the concessionaire in its offer in toll motorway concessions in Spain during the first few years of operation (ramp-up period). We obtain the result that, on average, there is a clear bias towards overestimation though the behaviour of any single concession may not have much to do with the average. In addition, we found that unlike what happens with annual traffic volumes, traffic growth rates are mostly underestimated by concessionaires in the ramp-up period. We explain this trend towards overestimation in the strategic behaviour of the bidders in the tender rather than in systematic modelling errors. The cause of this strategic behaviour lies in the willingness to renegotiate as shown by the government of Spain when actual traffic turns out to be lower than expected

Land use / land cover change (2000 – 2014) in the Rio de la Plata grasslands : an analysis based on MODIS NDVI time series

Instituto de Investigaciones Fisiológicas y Ecológicas Vinculadas a la Agricultura (IFEVA). Laboratorio de Análisis Regional y Teledetección (LART) Buenos Aires, Argentina.22Latin America in general and the Rio de la Plata Grasslands (RPG) in particular, are one of the regions in the world with the highest rates of change in land use/land cover (LULC) in recent times. Despite the magnitude of this change process, LULC descriptions in the RPG are far from being complete, even more those that evaluate LULC change through time. In this work we described LULC and its changes over time for the first 14 years of the 21st century and for the entire grassland biome of the Rio de la Plata, one of the most extensive grassland regions in the world. We performed simple but exhaustive classifications at regional level based on vegetation phenology, using extensive LULC field database, time series of MODIS NDVI satellite images and decision trees classifiers, generating an annual map for all RPG. The used technique achieved very good levels of accuracy at the regional (94.3%–95.5%) and sub-regional (78.2%–97.6%) scales, with commission and omission errors generally low (Min = 0.6, Max = 10.3, Median = 5.7, and Min = 0, Max = 41.8, Median = 6.8 for regional and sub regional classification respectively) and evenly distributed, but fails when LULC classifications are generated in years when the climate is very dierent from those used to generate spectral signatures and train decision trees, or when the NDVI time series accumulates large volumes of lost data. Our results show that the RPG are immersed in a strong process of land use change, mainly due to the advance of the agricultural frontier and at the expense of loss of grassland areas. The agricultural area increased 23% in the analyzed period, adding over than 50,000 Km2 of new crops. Most agricultural expansion, and therefore the greatest losses of grassland, concentrates on both sides of Uruguay river (Mesopotamic Pampa and the western portion of Southern and Northern Campos) and the western portion of Inland Pampa. The generated maps open the door for more detailed and spatially explicit modeling of many important aspects of ecosystem functioning, for quantification in the provision of ecosystem services and for more efficient management of natural resources

Highly selective chemical reduction of nitrate in water in carbon-based contactor catalytic membrane reactors

A carbon-based catalytic membrane reactor in a contactor (interfacial) configuration has been used as an approach to control selectivity in the reduction of NO3- in water. Water and hydrogen fed to the reactor circulate tangentially on opposite sides of the membrane, which acts as a separator and contactor, enabling hydrogen transfer to the water phase. Powdered carbons (carbon black, carbon nanofiber, and activated carbon) were used to prepare catalytic membranes that also acted as contactors to transfer H2 from the gas phase to water. The membranes based on the Pd-Cu/carbon black catalyst showed lower selectivity towards unwanted NH4+ than the Pd-Cu and Pd-Sn catalysts supported on carbon nanofibers and activated carbon, due to a good balance among conductivity, external surface area, and particle size. Sensitivity analysis for H2 partial pressure demonstrated that the contactor membrane reactor can be operated with control of H2 mass transfer, hence enabling enhanced control of the selectivity to NH4+. Additional control of selectivity was achieved by reducing the catalytic layer thickness of the membrane, which improved NO3- transport and decreased the H/N ratio at the active centers. With these approaches, NO3- conversion values above 40 % with negligible NH4+ production and NO3- conversions close to 60 % with NH4+ selectivity values around 3 % were achievedRTI2018–098431-BI00, PID2021–122248OB-I0
