Avance resumido de la monografía posterior 'Epigrafía Romana de la Beturia Céltica' (Madrid, UAM, 1997: https://www.academia.edu/6936842/Epigraf%C3%ADa_Romana_de_la_Beturia_C%C3%A9ltica_ERBC_1997_libro_completo ), donde todas las ideas principales se explayaron más, junto con el catálogo de inscripciones de esta tan importante zona occidental de la vieja "regio" de la Baeturia, dedicada a la explotación de hierros, a la ganadería y a la agricultura, vertebrada en torno a la cuenca del río Ardila y a una altura media s.n.s. de 500 m. Hay en él referencias a trabajos anteriores de 1991, 1993, 1995... (cf. todos ellos ya en Academia.edu), aunque hay también otros posteriores, de 1996, 2011,  etc.  En éste se han añadido ahora al texto estrellas y subrayados en los puntos que la autora considera más novedosos o interesantes, y algunas notas en azul a propósito de usos indebidos (o silencios) por otros autores de algunas ideas y materiales.

Administratively, the research area is located in PT. Vale Indonesia Sorowako region, District of Nuha, Luwu Timur Regency, Province of South Sulawesi This research is aimed to determine the grains size of soil with the content of the elements Ni, Fe, and S / M high in the zone of saprolite-type west block and east block, know the grains size of soil with with the content of the elements Ni, Fe, and S / M were lower in the saphrolite zone type west block and east block, and determine the ratio and the effect of soil grain size in improving the quality levels of Ni, Fe and S / M with analysis XRF method.
Based on research gained 30 sample <25.4 mm of west block and east block type. Each sample then preparated become 7 grain size. The 7 grain size are >6.35 mm, <6.35 – 1.67 mm, <1.67– 0.14 mm,  <0.14 – 0.10 mm, <0.10– 0.07 mm, and <0.07 mm. In type deposition west block, the highest concentration of Ni elements found in the grain size of <0.10 to 0.07 mm that is equal to 2.47%; levels of the elements Fe and SiO2 / MgO (S / M) is the highest found in the grain size of <0.07 mm is equal to 26.57% Fe and 3.11% of the elements on the levels of SiO2 / MgO (S / M). In type deposition east block, the highest concentration of Ni elements found in the grain size of <0.14 to 0.10 mm mm that is equal to 2:04%; The highest levels of Fe element found in grain size <0.07 mm is equal to 28.38%; and levels of SiO2 / MgO (S / M) is the highest found in the grain size of <0.10 to 0.07 mm mm that is equal to 2.4%. In type deposition west block, the levels of the elements Ni, Fe element, and SiO2 / MgO (S / M) the lowest common in grain size >6.35 mm is $ 1.41% for the elements Ni, 10.72% for the elements Fe, and 2.4 % for SiO2 / MgO (S / M). In type deposition east block, the levels of the elements Ni, the elements Fe and SiO2 / MgO (S / M) the lowest common in grain size >6.35 mm is equal to 1.65% for the elements Ni, 13.9% for the elements Fe, and 1.67% for SiO2 / MgO (S / M). There is an opportunity to increase levels of Ni element is to remove material ¼ mesh size fraction. The increase in Ni element in the area of West block of 7% by weight lost by 17.81. In the area of East block of 3% by weight of the weight lost by 17:49%.

The influence of reaction mixtures’ рН within the range 1 – 4.5 on oxidation process of indigo carmine and 3-nitropherol using the systems of Ruff and Fenton was studied. It was demonstrated that in the course of both substrates’ oxidation in reaction mixtures nano-sized particles of ferrum oxide hydrate are formed, the number of which depends on pH value. The value of [zeta]-potential gives evidence about interference of substrate molecules or intermediate oxidation products in agglomeration. Presence of agglomerates facilitates oxidation.
