About the Triple A. Argentina 1973 - 1976

On May 25, 1973, Peronism returned to govern Argentina after about two decades of prohibition and political persecution. After its establishment, certain crimes began to be signed with “AAA”. The Triple A adopted the particularity of disappearing with the coup on March 24 1976. Why could this organization only exist in a democracy erected in the middle of two military dictatorships? Why did it exist during the very wished Peronist government? The article offers an approach to the Triple A, that is, from the perspectives of history, sociology and politics. It seeks to unravel the socio-historical conditions of the Triple A by analyzing the international, ideological, utilitarian and strategic factors. Our hypothesis is that this illegal group failed in trying a strategy of non-state conducted repression, which ended up legitimizing the coup option crowned on March 24, 1976.

La relación entre el crimen organizado transnacional en la triple frontera y la politica exterior de seguridad de Brasil, Argentina y Paraguay entre 1996 y 2006

Esta monografía analiza la influencia del Crimen Organizado Transnacional en la Triple Frontera compartida por Argentina, Brasil y Paraguay y sus decisiones en Política Exterior durante 1996 y 2006. Se explica cómo el Crimen Organizado Transnacional y sus efectos en la gobernabilidad de los Estados pueden ser un motivo para el análisis de la situación como un Complejo de Seguridad Regional. A partir de la conceptualización de Seguridad Regional de Barry Buzan y Ole Waever y de Robert Stewart y Derrick Frazier, se avanza hacia el resultado de la investigación que permite exponer los factores que conllevaron a el surgimiento de un Complejo de Seguridad Regional entre Argentina, Brasil y Paraguay para diezmar los efectos del Crimen Organizado Transnacional en la Triple Frontera.

Formation of triple helical nanofibers using self-assembling chiral benzene-1,3,5-tricarboxamides and reversal of the nanostructure's handedness using mirror image building blocks

Intertwining triple helical nanofibers with an overall handedness have been formed from self-assembling chiral benzene-1,3,5-tricarboxamides 1, 2 and 3, whereas the achiralbenzene-1,3,5-tricarboxamide 4 upon self-association gives rise to straight nanofibers without any twist and transmission electron microscopy images of chiral compounds clearly demonstrate that the handedness of the triple helical nanofibers can be reversed by using the enantiomeric benzene-1,3,5-tricarboxamide building blocks.

Building integration photovoltaic module with reference to Ghana: using triple junction amorphous silicon

This paper assesses the potential for using building integrated photovoltaic (BIPV) roof shingles made from triple-junction amorphous silicon (3a-Si) for electrification and as a roofing material in tropical countries, such as Accra, Ghana. A model roof was constructed using triple-junction amorphous (3a-Si) PV on one section and conventional roofing tiles on the other. The performance of the PV module and tiles were measured, over a range of ambient temperatures and solar irradiance. PVSyst (a computer design software) was used to determine the most appropriate angle of tilt. It was observed that 3a-Si performs well in conditions such as Accra, because it is insensitive to high temperatures. Building integration gives security benefits, and reduces construction costs and embodied energy, compared to freestanding PV systems. Again, it serves as a means of protection from salt spray from the oceans and works well even when shaded. However, compared to conventional roofing materials, 3a-Si would increase the indoor temperature by 1-2 °C depending on the surface area of the roof covered with the PV modules. The results presented in this research enhance the understanding of varying factors involved in the selection of an appropriate method of PV installation to offset the short falls of the conventional roofing material in Ghana.

On the universal TRO of a JC*-triple, ideals and tensor products

In a development from material introduced in recent work, we discuss the interconnections between ternary rings of operators (TROs) and right C*-algebras generated by JC*-triples, deducing that every JC*-triple possesses a largest universally reversible ideal, that the universal TRO commutes with appropriate tensor products and establishing a reversibility criterion for type I JW*-triples.

Fractal geometry of aggregate snowflakes revealed by triple wavelength radar measurements

Radar reflectivity measurements from three different wavelengths are used to retrieve information about the shape of aggregate snowflakes in deep stratiform ice clouds. Dual-wavelength ratios are calculated for different shape models and compared to observations at 3, 35 and 94 GHz. It is demonstrated that many scattering models, including spherical and spheroidal models, do not adequately describe the aggregate snowflakes that are observed. The observations are consistent with fractal aggregate geometries generated by a physically-based aggregation model. It is demonstrated that the fractal dimension of large aggregates can be inferred directly from the radar data. Fractal dimensions close to 2 are retrieved, consistent with previous theoretical models and in-situ observations.
