Human Processing of Rodents in Patagonia: The Relevance of Historical and Ethnographical Data for Archaeological Interpretations

The consumption of small mammals was a widespread practice between indigenous societies worldwide. Modern taphonomic studies carried out upon bone assemblages from archaeological sites in northern Patagonia (Argentina) demonstrate thatCaviomorph rodents were also included in the diet of Patagonian populations, both from the steppe and the forests, at least since the Late Holocene. The revision of historical and ethnographical documents written by priests, naturalists and ethnographers during c.XVI-XX allow to corroborate that rodents were intensively exploited in Patagonia, continental and insular. Bones, meat and skin of the animals were employed for diverse purposes, and the gathering activity was guided by women and children.Fil: Andrade, Analia.

InGaN LEDs for General Lighting: Overcoming Efficiency Droop at High Current Injection

According to the Energy Information Administration\u27s Annual Energy Outlook report in 2011, the United States alone consumed 97.8 quadrillion Btus (quads) of primary energy in 2010. Roughly 41% of this energy was consumed for electricity use, with 18% of the electricity being dedicated to lighting. The International Energy Agency (IEA) estimated light consumption of this scale translates to CO2 production equivalent to 70% of the emissions from all of the world\u27s light passenger vehicles. Pollution levels at this rate caused 18,200 premature deaths, 2,100,000 days of medication, and 29 million cases of lower respiratory symptoms

Does memory priming during anesthesia matter?

This editorial argues that there is evidence for memory priming during adequate anaesthesia, and that research in the field of social cognition suggests that such priming may have important behavioural consequences. Comments made in the operating room about a patient's prognosis, appearance or state of consciousness could exacerbate their existing anxieties about the operation, themselves or the anaesthetic and may contribute to postoperative anxiety, depression and insomnia
