Effect of organic and inorganic consolidation agents on Tlaltecuhtli monolith

A huge monolithic piece corresponding to the first years of the sixteenth century has been discovered in Mexico City. It represents the earth goddess Tlaltecuhtli. The preservation of such a magnificent piece is imperative. Therefore, the surface has to be characterized and the interaction of consolidants with the rock has to be understood.Some of the consolidation methods are impregnation of the mineral with nopal or silicic acid derivatives. In this work we compare the physico-chemical effects of organic and inorganic consolidants. Original and impregnated samples are characterized with a series of original techniques: X-ray diffraction, nuclear magnetic resonance, nitrogen adsorption and small angle X-ray scattering. Fractal dimension, specific surface area and pore size distribution clearly differentiated the samples. The organic materials, nopal gum or slobber, cover the mineral particles with a smooth layer. The KSE solutions react and lead to microporosity.     

Regulation,integration and sustainability in the cultural sector

The paper examines the hypothesis of vertical integration between heritage and the performed arts. This is often a response to scarcity, and in many cases it implies conversion of heritage back to its original function. Various issues arise, due to the dilemma given by the potential cost for future generations of a more intensive present exploitation. On the other hand, many benefits are likely to be generated on cultural, economic and financial grounds. Furthermore, the decision‐making processes become quite complex, and adequate changes in regulation are necessary in order to make such a vertical integration consistent with culturally sustainable growth.     

The Protection of the Site: Discursive Formation and Self-identification in Contemporary Society

The paper argues that rescue archaeological activities in Japan create a discursive space where the future protection and management of the site is debated, notably between academic archaeologists, developers (the financial/administrative force) and the media. This discursive space is more and more dominated by the media agenda, to which the academic force largely conforms.This is connected with the nature of the stability of the lives of the rescue excavation officers themselves, in contradistinction to that of the general public.     

Charity as a Means of Zoroastrian Self-Preservation

Zoroastrian theology's emphasis on living the good life; the encouragement to create material wealth with the accompanying social obligations to put it to good use, explains the immensely extensive welfare system put in place by the Parsi community in India. Following the Arab conquest of Iran, the diminution in numbers and stature of the Zoroastrians in the ancestral land and the subsequent Parsi settlement in India, meant the marginalization of a people whose forebears once ruled a mighty empire. Once the Parsis acquired financial success, they put in place a community-wide network of benevolent institutions. This was followed by extending a muscular benevolence to the Zoroastrians of Iran, which evolved into a highly structured undertaking to ensure the safeguarding of the community from virtual extinction. Thus, Zoroastrian philanthropy was as much a reaffirmation of religious traditions as it was a means of self-preservation.     

Starch residues on museum artefacts: implications for determining tool use

A sample of 11 museum artefacts was examined to assess the preservation of any adhering organic residues, particularly starch granules, and to assess the potential for the identification of cooked starchy foods. The primary aim was to examine starchy deposits, extract starch granules and examine their physical condition to increase our understanding of the taphonomy of starch granules and associated organic residues in archived material and archaeological deposits. The study shows that organic plant residues could be recovered from archived artefacts and makes a significant contribution to understanding the function of this material. Recovered starch granules showed an interesting pattern of varying organic preservation on the surface of stone and wooden artefacts. Some starch granules were found to be well preserved while others in the same sample appeared to have been affected by enzyme degrading micro-organisms. Recovered residues included fully gelatinised starch.

Civiliser en Grèce Ancienne Adoucir la Nature et Naturaliser la Force

Ancient Greeks had neither a single notion nor a single word to express the idea of civilization. As a process of living since the origins, civilization appears as a serie of acquisitions or losses that lead to an ambivalent human condition. As a state, it is a blend of three factors: a diet and an education that tame nature; a legal political system and just foreign politics. But in the Greek language, the same word expresses a political system and domination (archê). Dionysius of Halicarnassus by speaking of the Roman domination as a just and natural phenomena, makes it a civilizing power.     

Reburial of shipwrecks in marine sediments: a long-term study on wood degradation

Historical shipwrecks in marine environments are continuously decomposed by wood-degrading organisms, adapted to this specific environment. To protect the wrecks from degradation and to preserve the unique remains for future generations, reburial of wrecks using various covering materials has been suggested as a long-term preservation method. The following experiment was carried out to study the bio-protective effect of sediment. Sound oak, pine, and birch samples were buried above and within marine sediment in Marstrand harbour, and retrieved for analysis after 6, 12, 24, and 36 months. Macroscopic as well as light-microscopic examinations were carried out on each occasion. Marine borers (shipworm, Limnoria), soft rot and tunnelling bacteria were wood degraders immediately above the seabed; soft rot, tunnelling bacteria, and erosion bacteria were active 10 cm below the seabed; erosion bacteria were the only degraders at a depth of 43 cm below the seabed. The wood species had different durability towards the decay agents. After 3 years, wood samples above the seabed were totally decomposed, whereas wood was highly protected at 43 cm depth in sediment. In the sediment, decay decreased significantly with depth of burial. The results suggest that reburial of shipwrecks in marine sediment can be recommended as a simple and efficient method for long-term preservation of the wooden cultural heritage.     

四川绵阳出土的西汉饱水漆木器的前期保护工作

为保护四川绵阳出土的西汉饱水漆木器,使用脱水定型法对20件物进行了保护。选用甲醇脱水,十八烷醇加固定型的方法,继而作旧,封护。结果表明,经保护处理的物,其弦向平均收缩率为8％左右,径向平均收缩率为1％左右,说明保护处理是成功的。实验说明,甲醇一十八烷醇脱水定型法具有普遍的推广意义。
