Little attention has been given to the study of combustion structures in the Prehispanic urban sites of the Central Andes. Our study focused on a sample of the combustion areas registered during the 20 years of research at Huacas del Sol y de la Luna. This study begins with a proposed typology for these structures, as well as an initial proposal co...

This article analyses the ethical consequences for archaeology and archaeologists induced by the process of capitalist globalisation and the integration of archaeological heritage as a resource within the market economy. I propose a theoretical reflection on the current situation as well as on the questions and repositioning of the different actors...

This paper presents a synthetic overview of the results of a multidisciplinary approach –archaeological, experimental and ethnographic – that provides new insights into the fire-related management strategies (from firewood procurement to fire use and cleaning activities) adopted by Yamana groups. We bring to the fore the significance of recent resu...

The site of Crvena Stijena offers an extraordinary opportunity to study a very long sequence of Neanderthal occupations where the traces of fire are well preserved. In this sense, Crvena Stijena could be included in the short list of Lower and Middle Paleolithic sites with features containing abundant ash and charcoal and exhibiting a substrate of...

Hunter-gatherers collected and used various woody species depending on the landscape, availability of plant communities, and sociocultural considerations. With extensive paleo-wetlands and groundwater-fed oases, the Atacama Desert was interspersed with riparian woodlands that provided vital resources (fuel, water, and game) at the end of the Pleist...

This paper deals with the heat transfer between two spherical grains separated by a small gap; dry air is located around the grains and a liquid water meniscus is supposed to be present between them. This problem can be seen as a micro-scale cell of an assembly of solid grains, for which we are looking for the effective thermal conductivity. For a...

The west European Neolithic is famed for its funerary and ceremonial monuments, but the evidence for houses is sparse. Can this be explained by the materials of which they were built? On the northern coast of Brittany, the site of Lillemer rises from the surrounding marshes and presents abundant evidence of Middle Neolithic occupation, contemporary...

The report is basically divided into two main parts. In the first part, we introduce a numerical strategy in both 1D and 3D axisymmetric coordinate systems to estimate the thermophysical properties of the soil (volumetric heat capacity (ρC)s , thermal conductivity λs and porosity φ) of a saturated porous medium where a phase change problem (liquid/...

Studying the Mallaha fire structures is a challenge to understanding how the behavior of hunter-gatherers changed during the first steps of sedentary life. For this purpose it is critical to analyze the different kinds of fire structures, including their shapes and functionality during the history of the various occupations of the site, their contr...
Article
In this paper, the authors introduce a robust numerical strategy to estimate the temperature dependent heat capacity, thermal conductivity and porosity of a saturated porous medium, basing on the knowledge of heating curves at selected points in the medium. In order to solve the inverse problem, we use the least squares criterion (in which the sens...

Abstract Studies conducted for several years in the Province of Buenos Aires tend to establish chronological sequences and models of adaptive strategies of hunter-gatherer groups that inhabited the region during the course of the Holocene. The establishment of such models can only be done through a clear definition of the functionality of the Pampe...

Para muchos el fuego nos hizo humanos, nos permitió cocinar los alimentos y de este modo transformar cultural-mente el sustento crudo en cocinado. Como el lenguaje o el pensamiento simbólico, la cocción es una práctica típi-camente humana que nos desmarca de la naturaleza (Lévi-Strauss, 1965). La domesticación del fuego supuso una revolución en las...

This paper treats a one dimensional phase-change problem, ’ice melting’, by a vertex-centered finite volume method. Numerical solutions are obtained by using two approaches where the first one is based on the heat conduction equation with the basic grid (improved by introducing a new adaptive mesh technique), latent heat source approach (LHA), whil...
