We present a case of a myxoid and lipomatous solitary fibrous tumor that was observed in a 67-year-old man. The tumor, which had a maximum diameter of 10 cm, was located in the soft tissues of the dorsal region and appeared macroscopically well delimited and encapsulated. Upon cutting, a markedly gelatinous internal surface was observed. A microscopic study revealed an intense and diffusely myxoid neoplasia, with small areas of adipose aspect, in which histological (staghorn vessels, perivascular hyalinization, fusiform cells of benign aspect) and immunohistochemical (intensive positivity for CD34, Bcl-2 and Cd99 and negativity for muscle markers) data were consistent with a solitary fibrous tumor were observed. To conclude, the main characteristics of this lesion are discussed, and a differential diagnosis is established with other entities.

The Global Reaction Model describes a set of chemical reactions that can potentially occur during the process of obtaining silicon rich oxide (SRO) films, regardless of the technique used to grow such films which are an outside stoichiometry material. Particularly, chemical reactions that occur during the process of growing of SRO films by LPCVD technique are highlighted in this model. We suggest and evaluate either some types of molecules or resulting nanostructures and we predict theoretically, by applying the density functional theory, the contribution that they may have to the phenomenon of luminescence which is measured in SRO films. Also, we have calculated the opto-electronic properties of SRO films. The suggested model provides enough information required to identify the molecular structures resulting from the presence of defects in SRO films and also those corresponding to charged structures. It is also possible to detect the molecular structures which are modified due to the effect of heat treatment, and identify the presence of different oxidation states inclusive the formation of siloxanes.

The amalgamation of the southern Rio de la Plata craton involves two possibly coeval Rhyacian sutures associated with the Transamazonian orogeny, rather than a single one as previously envisaged, i.e. the El Cortijo suture zone and the Salado suture. We circumscribe the Tandilia terrane to the region between these two sutures. The E1 Cortijo suture zone runs along a roughly WNW oriented magnetic low aligned along the southern boundary of the Tandilia terrane, i.e. boundary between the Tandilia and Balcarce terranes. This extensive magnetic low, ca. 300 km long, and ca. 90 km wide, would be caused by demagnetization associated with shearing. At a more local scale, the trend of the El Cortijo suture zone often turns toward the E-W. At this scale, WNW trending tholeiitic dykes of Statherian age are seen to cut the Rhyacian E1 Cortijo suture zone. Spatially associated with the El Corti]o suture zone, there are small magnetic highs interpreted to be related to unexposed basic bodies of ophiolitic nature related to those forming part of the El Cortijo Formation. We envisage the pre-Neoproterozoic evolution of the Tandilia belt to have been initiated by the extension of Neoarchean （ - 2650 Ma） crust occurred during Siderian times （2500-2300 Ma）, causing the separation between the Balcarce, Tandilia and Buenos Aires terranes, and the development of narrow oceans at both north and south sides of the Tandilia terrane, accompanied by -2300-2200 Ma sedi- mentation over transitional -continental to oceanic- crust, and arc magmatism developed in the Tan- dilia terrane. The island arc represented by the El Cortijo Formation was also developed at this time. At late Rhyacian times, it occurred in both the closure of the narrow oceans developed previously, the entrapment of the El Cortijo island arc, as well as anatectic magmatism in the Balcarce terrane.
