RESUMO
Several aspects of past culture, including historical trends, are inferred from time-based patterns observed in archaeological artifacts belonging to different periods. The presence and variation of these objects provides important clues about the Neolithic revolution and given their relative abundance in most archaeological sites, ceramic potteries are significantly helpful in this purpose. Nonetheless, most available pottery is fragmented, leading to missing morphological information. Currently, the reassembly of fragmented objects from a collection of thousands of mixed fragments is a daunting and time-consuming task done almost exclusively by hand, which requires the physical manipulation of the fragments. To overcome the challenges of manual reconstruction and improve the quality of reconstructed samples, we present IberianGAN, a customized Generative Adversarial Network (GAN) tested on an extensive database with complete and fragmented references. We trained the model with 1072 samples corresponding to Iberian wheel-made pottery profiles belonging to archaeological sites located in the upper valley of the Guadalquivir River (Spain). Furthermore, we provide quantitative and qualitative assessments to measure the quality of the reconstructed samples, along with domain expert evaluation with archaeologists. The resulting framework is a possible way to facilitate pottery reconstruction from partial fragments of an original piece.

A transversal study was conducted at the University City campus of the National Autonomous University of Mexico (UNAM) in Mexico City, with the goal of estimating the university community preference for drinking either tap water or bottled water and the reasons for their selection. A representative sample of three university community subpopulations (students, workers/administrative staff, and academic personnel) were interviewed with respect to their water consumption habits. The results showed that 75% of the university community drinks only bottled water and that the consumption of tap water is low. The interviewees responded that the main reason for this preference is the organoleptic features of tap water independent of quality. In general, the participants in this study do not trust the quality of the tap water, which could be caused by the facilities that distribute bottled water encouraging a general disinterest in learning about the origin and management of the tap water that is distributed on campus.

El propósito de este estudio es determinar la frecuencia de anticuerpos anti-tiroideos (anti-tiroglobulina y anti-microsoma) en pacientes con lupus eritemaso sistémico y artritis reumatoide. Cuarenta y seis pacientes con lupus y 73 pacientes con artritis reumatoide fueron estudiados y comparados con 110 controles (donadores de sangre). Los resultados mostrados anticuerpos en 12 pacientes con lupus (26.9 por ciento), en 9 pacientes con artritis reumantoide (12.3 por ciento) y en 9 donadores de sangre (8.1 por ciento). Cuatro pacientes con artritis reumatoide (5.47 por ciento) presentan hipotiroidismo y 1 hipertiroidismo (6.5 por ciento). En conclusión los pacientes con lupus eritematoso sistémico, tienen una frecuencia aumentada de anticuerpos anti-tiroides, cuando se comparan con la población normal (p. 0.01)
