On the north coast of present-day Peru, between the Andes and the Pacific Ocean, prospered approximately between 1000 BC and 1375 AD, several relevant cultures: Chavín (1000-200 BC), Vicús and Frías (200 BC - 300 AD), Moche (400 BC-700 AD), Sicán (700-1375 AD). These cultures are interconnected and characterized by a high metallurgical ability, demonstrated by the presence of beautiful artifacts on gold, silver and copper alloys. More than hundred metal artefacts from these cultures were analyzed with a portable equipment which uses the non-destructive and non-invasive technique of energy-dispersive X-ray fluorescence (EDXRF). Following objects were analyzed: (1) gold, silver and copper objects from the Chavín culture (Museo Municipal of Piura and and Museo Enrico Poli in Lima); (2) gold and silver objects from the Vicús and Frías cultures (Museo Municipal of Piura); (3) gold, silver and copper objects from the Moche culture ("Museo Tumbas Reales de Sipán", "Museo de Sitio de Huaca Rajada" in Lambayeque and Museo Enrico Poli in Lima); (4) gold, silver and copper objects from the Sicán culture (Museum of Sicán, Ferra?afe). Portable equipments were employed, mainly composed of a small size X-ray tube and a thermoelectrically cooled, small size, Si-PIN or Si-drift X-ray detectors. The main characteristics of the EDXRF-technique is of being non destructive and multi-elemental. Standard samples of gold and silver alloys were employed for calibration and quantitative analysis. The aims of this campaign of analysis were: (1) to analyze a large number of objects; (2) to differentiate gold, gilded copper and tumbaga (this last being a poor gold alloy enriched at the surface by depletion gilding); (3) to correlate, when possible, composition of analyzed alloys to the specific culture; (4) to determine a possible evolution of metallurgy; (5) to better determine characteristics and beginning time of tumbaga production. It was determined that the analyzed artefacts are composed

Background:In Brazil,people still fall ill and die from tuberculosis(TB),and this can be explained by the significant impasse in the equity of distribution of therapeutic resources to the population as a *** aim was to identify geographical areas which have shown progress in terms of equity(of income,schooling and urban occupancy)and test its effect on mortality from TB in a municipality of southeast ***:It is an ecological study considering TB as the basic cause for deaths registered between 2006 and 2013 on the Mortality Information System and other variables obtained through the Demographic Census of the Brazilian Institute of Geography and Statistics(2010).The geographical area for analysis comprised the areas of coverage of the health *** indicators have been constructed through the Principal Component Analysis(PCA).The cases were geocoded and the annual mortality rate from TB was calculated with smoothing using the local empirical Bayesian *** linear regression was then *** was confirmation of the existence of spatial dependence of residue through the application of the Global Moran I test,and application of the Models with Global Spatial Effects,to identify the best standard of spatial ***:The mortality rates ranged from 0.00 to 2.8 deaths per 100,000 people,per *** the PCA,three indicators were constructed,and designated as indicators of income,social inequality,and social *** multiple linear regression,the indicator of social equity was statistically significant(P<0.0001)but had a negative association,an adjusted R^(2)of 28.36%and with spatial dependence(Moran I=0.21,P=0.003455).The best model to deal with existing spatial dependence was the Spatial Lag ***:The better social conditions have shown progress in reducing mortality from TB,thereby reinforcing the achievement of Sustainable Development *** addition,cartography was also applied,which can be replicated
