چکیده

Charcoal fragments from five historic campsite locations in the Galápagos Islands were identified and radiocarbon dated to investigate postulated early human presence in the archipelago, historic fuel wood collection patterns and the resultant impact on native vegetation. A variety of taxa and fuel types were revealed to be present in the charcoal assemblages, indicating geographically driven rather than species-specific methods of collection. Historic anthropogenic impact was therefore spread amongst woody taxa in the lowland plant communities, with severity dependent on proximity to campsite location. All charred remains were found to date from within the historic period, supporting the preponderance of archaeological evidence indicating that human presence did not begin in Galápagos until after European discovery.

The Effect of Air Fuel Ratio and Temperature on Syngas Composition and Calorific Value Produced from Downdraft Gasifier of Rubber Wood-Coal Mixture

Rubber wood (Ficus elastica) is one the biomass waste that can be used as raw material for a gasification process and has a calorific value of 4,069 cal/gram. Gasification is a process to convert a solid fuel to syngas (CO, CH4, and H2) through a combustion process using limited air between 20% to 40% of air stoichiometry. Depending on the direction of airflow, the gasifiers are classified as u...

Charring does not affect wood infestation by subterranean termites

Fire is an important part of forest ecosystems, as is the insect fauna. Changes in wood brought about by fire may alter the ability of termites to use the wood, interrupting the decay cycle of woody debris. The ability of termites to find, infest, and feed upon wood after it had been charred was evaluated in the laboratory and field. Eastern subterranean termites, Reticulitermes flavipes (Kolla...

Intentional Burning of Dung as Fuel: A Mechanism for the Incorporstion of Charred Seeds Into the Archaeological Record

An important concern of paleoethnobotanists is accounting for the presence and charring of seeds recovered archeologically. The possibility that seeds can be brought to a site incorporated in animal dung and charred when that dung is burned as fuel is considered. Researchers have shown that animal dung can contain seeds. Ethnoarcheological data from the rural village of Malyan, Iran demonstrate...

In the third millennium B.C., the inhabitable zones in the southern part of Sistan Plain were confined to the deltaic lands around the Rud-i Biyaban River. One of the main climatological characteristics of that time was the abundance of water resources in the Hilmand basin. The formation and dynamism of human settlements in this region have always been related to the water fluctuations of the H...
