“…In general, the percentages of total nitrogen removal ( The high standard deviation (>10%) observed in the case of FeCl 3 is due to the high nitrogen removal percentage (98.7%) achieved in the experiment that operated at an initial hydrogen peroxide concentration of 20% (w/v), which is approximately double than that reached for the 7.5% of FeCl 3 . A possible reason for this behavior is that nitrogen is generated in specific conditions (abiotic N 2 fixation in presence of CO 2 abundance conditions [38,39]), which was not examined.…”

The high production of raw olive oil mill wastewater (OMW) is a current environmental problem due to its high organic load and phenol compounds. In this work, photo-Fenton reaction as an advanced oxidation process has been chosen for OMW treatment. In this sense, different iron salts (FeCl3, Fe2(SO4)3, FeSO4·7H2O, and Fe(ClO4)3) as catalysts were used in order to compare their effects on treatment. For each catalyst, different H2O2 concentrations (2.5, 5.0, 7.5, 10.0, 15.0, 20.0, and 30.0%, w/v) as oxidizing agents were tested. The common experimental conditions were temperature 20 °C, the catalyst/H2O2 ratio = 0.03, pH = 3, and ultraviolet light. The Lagergren kinetic model, in cases of total organic carbon removal, for the best H2O2 concentration per catalyst was used. During the experiments, the water quality was determined by measuring the removal percentages on chemical oxygen demand, total carbon, total organic carbon, total nitrogen, total phenolic compounds, total iron, turbidity and electric conductivity. The best catalyst was FeCl3 and the optimum H2O2 concentration was 7.5% (w/v). At these optimal conditions, the removal percentages for chemical oxygen demand, total phenolic compounds, total carbon, total organic carbon and total nitrogen were 60.3%, 88.4%, 70.1%, 63.2% and 51.5%, respectively.

“…Es la enzima más abundante en la Tierra (Gómez-Fernández, et al, 2018), que fue determinante en el origen de la vida al permitir la transformación del carbono inorgánico en carbono orgánico (Shih, et al, 2016). La reacción de conversión del CO 2 se ha venido dando desde hace más de 4.000 millones de años, cuando la atmósfera era aún predominantemente reductora (Trigo-Rodríguez, et al, 2013). La enzima rubisco ha evolucionado a través del tiempo, dando origen a la rubisco 1B en las plantas superiores, algas y la mayoría de las cianobacterias, y a la rubisco 1A en las protobacterias y las cianobacterias marinas.…”

El dióxido de carbono es una molécula que ha estado presente en la Tierra desde su formación hasta nuestros días y participa en los diferentes ciclos de transformación del carbono. El más importante es el asociado a la conversión de carbono inorgánico a carbono orgánico a través del proceso de fotosíntesis catalizado por la enzima rubisco, el cual permitió el origen de la vida en la Tierra y el almacenamiento de energía solar durante millones de años en lo que hoy llamamos combustibles fósiles. En esta revisión se presenta un breve recuento de los cambios en la concentración atmosférica del CO2 desde su formación hasta nuestros días. Además, se discute la formación y el estudio de las estructuras químicamente complejas que caracterizan algunos de los combustibles fósiles, así como los mecanismos químicos por los cuales se recupera la energía almacenada y se vuelve a generar CO2 al usar dichos combustibles. Se analizan asimismo las implicaciones del uso acelerado de estos recursos en los últimos 150 años, lo que ha llevado el sistema “tierra” a un aumento crítico de la temperatura, con la consecuente necesidad de acciones urgentes para que el incremento sea inferior a 1,5 oC con referencia a la época preindustrial, pues, de no hacerlo, ello tendría consecuencias catastróficas para la vida en la Tierra.

“…Consequently, we think that there is growing evidence that JFCs can be formed, at least partially, by high-strength materials of chondritic nature. We envision that those reaching the top atmosphere at grazing angles and with moderate velocities (in other words, with the optimal geometrical conditions) could be a source of meteorites, but also of ablation-generated volatiles to Earth's atmosphere (Trigo-Rodríguez 2013).…”

We present the analysis of the atmospheric trajectory and orbital data of four bright bolides observed over Spain, one of which is a potential meteorite dropping event. Their absolute magnitude ranges from -10 to -11. Two of these are of sporadic origin, although a Geminid and a κ-Cygnid fireball are also considered. These events were recorded in the framework of the continuous fireball monitoring and spectroscopy campaigns developed by the SPanish Meteor Network (SPMN) between 2010 and 2012.The tensile strength of the parent meteoroids is estimated and the abundances of the main rock-forming elements in these particles are calculated from the emission spectrum obtained for three of these events. This analysis revealed a chondritic nature for these meteoroids.
