Tierra del Fuego represents the southernmost limit of human settlement in Americas. While people may have started to arrive there around 10 500 BP, when it was still connected mainland, main wave occupation occurred 5000 years later, by which time had become an island. The co-existence area maritime hunter-gatherers (in canoes) with previous terrestrial occupants pre-echoes culturally distinctive groups encountered first European visitors sixteenth century. study also provides a striking...
The aim of this work is to analyse and discuss a spectroscopic method diagnosis based on the Stark broadening emission lines determine electron density temperature in atmospheric-pressure plasmas. Usually, when previously known, certain spectral spontaneously emitted by plasma used rapid inexpensive way. However, comparing two or more can allow us diagnose simultaneously. To carry out cross-point method, we must know dependence for different lines. In have first three Balmer series hydrogen...
Historical ecology draws on a broad range of information sources and methods to provide insight into ecological social change, especially over the past ∼12000 yr. While its results are often relevant conservation restoration, insights from diverse disciplines, environments, geographies have frequently remained siloed or underrepresented, restricting their full potential. Here, scholars practitioners working in marine, freshwater, terrestrial environments 6 continents various archipelagoes...
Se presentan los resultados del estudio de un sondeo sitio arqueológico Tilly Este, ubicado en la bahía mismo nombre isla Carlos III, estrecho Magallanes (Chile). El yacimiento es conchal multicomponente canoeros que abarca ocupaciones pre-contacto y post-contacto histórico. registro indica presencia eventos ocupacionales con diferentes intensidades incluye, momentos históricos, una industria mayor diversidad actividades. Estos últimos registros se asocian abundantes materiales líticos...
This paper discusses the possibility of determining, at same time, both electron density and temperature in a discharge produced atmospheric pressure using Stark broadening lines spontaneously emitted by plasma. direct method allows us to obtain experimental results that are good agreement with others previously obtained for type discharge. Its advantages disadvantages compared other methods diagnostics, namely Thomson scattering, also discussed.
ABSTRACT Palaeoenvironmental data for the Late Glacial and Holocene periods are provided from Caleta Eugenia, in eastern sector of Canal Beagle, southernmost Patagonia. The record commences at c. 16 200 cal a bp following glacier retreat response to climatic warming. However, cooler conditions persisted during period. onset more temperate after 12 390 is indicated by arrival southern beech forest later establishment 10 640 , but woodland growth was restricted lower levels effective moisture....
Resumen es: El siguiente trabajo es una aproximacion al desarrollo de las estrategias pesca utilizadas por los grupos cazadores recolectores terrestres del norte ...
Presentamos los resultados obtenidos durante una investigación orientada a la identificación de yacimientos y análisis sus evidencias para reconstruir secuencias ocupación cazadores-recolectores marinos en diferentes puntos específicos Patagonia Meridional.En este trabajo abordamos caracterización tres arqueológicos localidad Punta Santa Ana, estrecho Magallanes.Los conjuntos estudiados corresponden campamentos emplazados distinta elevación sobre el nivel del mar actual, con antigüedades...
El desarrollo de una prospección arqueológica en la costa isla Dawson e Wickham, ubicadas posición estratégica entre las diferentes vías comunicación que conectan porción central del estrecho Magallanes con el archipiélago fueguino, registró 27 yacimientos corresponden a antiguos campamentos cazadores-recolectores marinos habitaron zona.La realización excavaciones sondeo seis estos sitios permitió recuperar un interesante conjunto restos arqueofaunísticos.A partir análisis éstos conjuntos,...
The context of an archaeological site with special characteristics, because it is immerse in a peat bog and for its dated age ca.4.000 BP, described.The lithic archaeofaunistic analysis Myren 2 support the idea that hard to ascribe functionally, thought contains interesting information outstanding character Tierra del Fuego.
Las primeras ocupaciones de canoeros, 6000 años AP en la zona del estrecho Magallanes y mar Otway, cuentan con importante información sobre caza mamíferos marinos su importancia el modo vida canoero (Legoupil 1997
A continuación se presentan los resultados obtenidos en trabajos de excavación y análisis del sitio Playa Negra 9 (PN-9) ubicado la bahía Concepción, región
We describe sclerochronological analyses of tadpole codling (Salilota australis) vertebrae as a proxy for the seasonal timing fishing activities at one Middle Holocene (6500 BP) and three Late–Middle (3500–2500 years archaeological sites located in Seno Otway central zone Strait Magellan, Chile. These data provide an approximation population characteristics species past by estimating relationship between size age fish comparing their growth rate to those modern specimens captured monthly...
We present an experimental study of a hydrogen plasma produced by microwave axial injection torch, launching the in helium-filled chamber. Three different diagnostic methods have been used to obtain electron density and temperature as follows: The Stark intersection method Balmer spectral lines (already tested argon helium plasmas); modified Boltzmann-plot showing that is far from local thermodynamic equilibrium but ruled excitation-saturation balance; disturbed bilateral relations theory....
The use of the Stark broadening Balmer lines spontaneously emitted by atmospheric-pressure plasmas as a method to determine both electron density and temperature in high-pressure is discussed this paper. This applied argon helium produced microwave discharges. Especially for Ar plasmas, valuable reliable results are obtained.
El sitio arqueológico Punta Baxa 7 es un extenso yacimiento caracterizado como agregado de diversas concentraciones material (conchales, talleres líticos
We present preliminary results of an experimental study a hydrogen plasma flame produced using microwave axial injection torch (torche axiale or TIA). This device usually runs in argon helium at atmospheric pressure providing stable discharge high HF power levels and two-temperature plasma. In the current work, is launched filled chamber to prevent hydrogen-air explosive reactions. Seven spectroscopic lines have been detected visible spectrum (the Balmer series hydrogen). Using Boltzmannplot...
