Full textAlsace has been profoundly marked by the textile industry. For two centuries, its textile heritage has experienced numerous fluctuations, rising and falling according to the structural and cyclical growth rate of the economy and to industrial crises. Fluctuations that, though completely random and uncontrollable (strategies, even short-term, cannot be implemented), have occurred in a timely manner, thus giving rise to constantly changing unique cultural, scientific, technical and industrial landscape.It is thus only right to wonder how the memory of the development of this industrial fabric can be preserved in all its complexity? There are three possible means of preservation: material (retro-presence to neo presence concept), immaterial (concept of memo-retroconstruction) and virtual (concept of what is "areal", clearly promoting position take-up on material and immaterial concepts to be protected). Even if all these possibilities exist side by side, one problem remains unanswered, namely what is the outlook for the preservation of the textile heritage in Alsace? The literature on preservation of industrial heritage available since the 1970s tends to overlook the existing relationships of interdependence between these three modes of preservation. The shortage of results does not allow us to appraise the potential offered by proper management of a combination of these three modes of preservation. This research work thus aims to propose some possible schemes to define a new preservation model, based on the example of the textile industrial heritage in Alsace. The first part of this study explains the processes that have allowed the textile industry in Alsace to accede to heritage status some 200 years ago. Choices guided by discretionary powers, opposable preservation logics, discontinuity in course of action over short and long periods alike, reclaiming more often oriented by lections rather than of a scientific nature, opting-out of those with responsibilities, not to mention the lack of coherence between players and institutions: these are all factors that will guide a Region's preservation policy strategy. What state of affairs can be drawn up today by historical sources? What is the outlook for the future? The second part asks the same questions, but this time seeks for the answers based only on media sources. It questions the pertinence of the current textile heritage preservation processes, material, immaterial and virtual alike, but from a viewpoint different from and complementary to the first part, namely the viewpoint of journalists and public and political contributors. Do communication sciences offer heritage reservation new horizons? Yes they do, but that is not all they offer. We shall see that, far from being mere tool, they play a decisive role in the reconstruction of a heritage, grouping themselves to move with society in order to define it by using all the meanings accumulated in the semes relating to the textile industrial heritage. Through this they form a collective reference, formulating hypotheses for future transformation, adaptation and projections. We shall then see whether it is possible for them to play a role in heritage preservation.The third part highlights the convergences and divergences of the three preservation modes. lt suggest concrete solutions for Alsace, followed by transposable concepts to extend these new preservation processes to other regions in France and, why not, to other areas
Pironti, Elinor Dei Tos. "The interconnection of culture and manufacture in Japanese No theater costume| Conservation of an Edo Period choken." Thesis, Fashion Institute of Technology, SUNY, 2016. http://pqdtopen.proquest.com/#viewpdf?dispub=10140949.
Full textThe subject of this qualifying paper is an Edo Period Nō theater chōken. Upon receipt, this choken was in very poor condition. There were six types of damage that needed treatment.
First, there was extensive warp breakage along the full length of the shoulders and sleeve bottoms and one area of full loss to the base fabric, exposing wefts. Second, a couched metallic thread was used as an outline to five vase motifs and as patterning for four butterflies. All used ‘urushi,’ better known as Japanese lacquer, for an adhesive binding a metal foil its paper substrate. This couched thread had either loss to the metallic surface, to the combined metallic and lacquer surface, or was hanging, and at times twisted back upon itself. Third, there was a cut and finely woven, metallic coated paper used for some of the leaf and insect wing motifs that was tattered, unaligned, had loss to its metallic surface, and was not secure to the base fabric. Fourth, there were areas of weft breakage exposing warps. Fifth, the six exposed selvages that run the full length of the two sleeves and one body panel all needed to be strengthened. Sixth, there was one 3 by 4 inch area in the lower back of the body panel which had complete fabric loss.
Untreated areas were: areas of warp distortion in the front body panel; a few loose embroidery threads throughout the five floral/vase motifs; and a small amount of loss due to insect infestation.
Research was done and methods developed in order to find treatment techniques for the lacquer based metallic thread, the cut and woven paper motifs, and the extensive warp breakage extending along the shoulders and sleeve bottoms.
Due to the difficulty of finding English equivalents to Japanese textile terminology, I included a Comparative Glossary that I hope will be useful to other researchers in this field.
This project proved to be challenging, but in the end, very rewarding with a new body of knowledge concerning materials used in this type of cultural object.

Full textThe preservation of biodiversity is a priority issue, both at national, European and international levels. In order to provide a better understanding of ecosystem functioning, spatial heterogeneity of natural environments is becoming one of the key components for the study of biodiversity. The Mediterranean basin is a hotspot of biodiversity for which the synergies between biodiversity and spatial heterogeneity of landscapes are particularly important. Mediterranean environments are organized into heterogeneous mosaics of four vertical strata~: bare soil, herbs, low ligneous and high ligneous. The biodiversity of these unique hotspots is now threatened by a closure of the landscape that leads to the habitat loss and landscape homogenization. The loss of heterogeneity is also leading to an increase in fire risks.This thesis aims to develop indices characterizing the spatial heterogeneity of natural landscapes in a Mediterranean context using very high spatial resolution remote sensing images. Among the various methods dedicated to the characterization of heterogeneity, the FOTO (FOurier Based Textural Ordination) method is particularly relevant because it produces uncorrelated texture gradients in an unsupervised manner, allowing continuous variations in spatial heterogeneity to be characterized at different spatial scales. Thus, the first objective of this thesis is to test the potential of texture indices derived from the FOTO method for the characterization of spatial heterogeneity relative to four vertical strata. The second objective is to test the sensitivity of our approach to technical and environmental factors, in order to ensure its replicability, and promote its use in an operational context of monitoring Mediterranean environments. Finally, based on a case study centered on the spatial distribution of bird species sensitive to vegetation heterogeneity, the last objective is oriented towards the validation of the ecological relevance of the heterogeneity indices.Combined with a vegetation index, NDVI, the texture indices derived from the FOTO method could be interpreted in terms of spatial heterogeneity and make it possible to characterize the composition and organization of the four vertical strata studied. These indices are influenced bymultiple factors, including the anthropization of landscapes showing patterns translated into surfaces such as crops, and the nature of the radiometric information of the remote sensing images processed. This pattern information impacts the apparent contrast of vegetation strata. Thus, the application of the method on a panchromatic band is more sensitive to patterns related to the alternation of bare soil and herbs while the application of the method on NDVI is more sensitive to patterns related to the alternation of ligneous strata with the herbaceous stratum. Finally, we have shown the interest of the approach developed for the prediction of several bird species with high conservation stakes. Heterogeneity indices have made it possible to highlight vegetation structures that are particularly favourable to certain bird species.The approach developed in this thesis is particularly stimulating because it allows the unsupervised production of three complementary indices characterizing several components of spatial heterogeneity related to four strata. Further efforts are needed to improve i) our understanding of the contribution of environmental and instrumental factors to the stability of the approach and ii) its automation for application in an operational context for mapping and monitoring the conservation status of natural habitats and birdlife

Full textDigitization is a major issue of interest in the field of cultural heritage, allowing on the one hand the long-term safeguard of collector’s pieces, and on the other hand to valorize them under a new revelatory way. In collaboration with the Musée d’Ethnographie de Bordeaux (MEB), this thesis work has the objective of proposing an innovative solution in terms of digitization, by answering the following problem : how to faithfully reproduce the appearance of a collector’s piece, such that the digital version is, to the eye, indistinguishable from the real object ? The size of the objects to be digitized as well as the resolution necessary to obtain the desired quality imply an astronomical quantity of measurements to be carried out, forming a real technical and scientific challenge. This thesis proposes to respond to this observation by producing an innovative imagebased acquisition prototype, formed by a dome covered with 1080 LEDs within which a camera on a robotic arm evolves. This work is first supported by a bundle of preliminary research, focusing on the theoretical and practical issues attached to such a measurement. This notably made it possible to highlight to what extent diffraction plays an important role in BRDF measurements, far beyond the usual criteria. In this sense, a new metrologically viable data processing algorithm has been proposed. Supported by these achievements, the digitization prototype has been designed, produced, calibrated and finally successfully used for the safeguarding of the cultural heritage. This new, constantly evolving instrument then lays the foundation stone for many areas of future research, both focused on optimizing the measurement process and on exploiting the generated data

Full textBecause of public health problems, the food industry must lower sodium content in all food products, therefore in cured meat products. During the dry-cured ham elaboration process, decreasing salt content may induce microbial safety problems and texture defects due to an excessive proteolysis that could affect later the industrial stage of slicing. On account of that, this work of thesis aims at (1) studying the relationship between proteolysis, structure and texture during the various stages of dry-cured ham manufacture, and (2) building a “numerical ham” model to predict spatially the time course of water and salt content, and thus water activity (a w ), and to couple these variations with proteolysis. This work combines experimental studies and numerical modelling and simulation. Firstly, a new and powerful technique for quantifying proteolysis that uses “Fluorescamine” was developed and validated on pork meat samples and samples extracted from industrial dry-cured hams; a new proteolysis index (PI) was defined. Based on an experimental design, the time course of proteolysis was quantified in laboratory-salted and dried pork meat samples prepared from five different types of pork muscle. Applying multiple linear regression enabled us to build phenomenological models relating, for each pork muscle, PI velocity to temperature, and to water and salt content. Using Comsol ® Multiphysics software, these phenomenological models were then combined with heat and mass transfer models and associated with calculation of a w , thus constituting the “numerical ham” model. In addition, the time course of PI, five textural parameters (hardness, fragility, cohesiveness, springiness and adhesiveness), and four structural parameters (fiber number, extracellular spaces, cross section area, and connective tissue area) was quantified on samples extracted from two different muscles of industrial dry-cured hams removed from the process at five different processing times. Multiple polynomial regression was applied to build phenomenological models relating PI, salt and water content to some textural and structural parameters investigated. These last models could be rapidly incorporated in the “numerical ham” model to constitute a real process simulator. In the future, the “numerical ham” model should be improved in order to take into account (1) the strong decrease in ham volume due to drying and also (2) the decrease in proteolysis velocity with time as a result of the reduction in the amount of protein that can be hydrolysed in the ham. Once completed and improved, the process simulator will be available to professionals to test scenarios allowing sodium content to be reduced in dry-cured hams without altering their final quality

This paper gives a innovative scientific research and supplementary anthropological field study on the glove puppet clothing embroidery products, which aims at achieving a simpler and more efficient preservation and conservation of a very unique cultural heritage of puppet art. Since Chiang, Jia-Zon glove puppets were made of extremely exquisite and precious historical textiles, non-destructive analysis methodologies are adopted for material characterization. We have developed an analytical system combined with multiple spectroscopic methods such as visible reflection, fluorescence, XRF, and FT-IR. Using these advanced testing machines, we are able to tell if the embroidery products that were used on the glove puppet clothing are organic or inorganic. These tested pairs include metallic material of embroidery threads, or the fiber; glasses or celluloid; organic colloid or inorganic material resin. In the past, to determine the nature of these material would usually be highly complex and tedious; however, here we will demonstrate a much simpler and efficient application of this analytical system. In addition to adopting non-destructive analysis methodologies, a supplementary field research has been conducted due to the lacking of related embroidery making process. This field study includes field research. Through the combination of both non-destructive testing of advanced lab technique and careful, detailed field research, scientific methodologies and anthropological study are brought together to create a more efficient identification of the material and hence better understanding and preservation of an unusually delicate embroidery material of Chiang, Jia-Zon glove puppets.

Full textX-Radiography is widely used in the investigation of works of art and other culturally significant artefacts to reveal and record details of their construction, modification and state of preservation. Radiography is considered to be a non-destructive technique but its increasing use in the study of historic textiles has prompted the testing of this assumption as X-rays and other forms of electromagnetic radiation, such as light and micro-waves, cause changes in materials which may be detrimental to their physical stability. An experiment was undertaken to test the safety ofradiography for the imaging of silk fabrics as these are particularly susceptible to photodegradation. The results from a series of radiographic exposures of modern and historic fabrics show that excessive exposure to low energy X-rays produced no detectable changes in their mechanical integrity. This indicates that the customary levels of radiographic exposure used in imaging will not be detrimental to textiles.

This study explored the in situ conservation principles and measures for textile collections adopted by the Bei-Gang Chao-Tian Temple (hereafter referred to as the Chao-Tian Temple); investigated the methods employed by the Chao-Tian Temple and surrounding folk art parade performance groups when preserving textile collections (to determine the feasibility of in situ conservation development); and analyzed efforts made and enthusiasm shown by the Chao-Tian Temple and the Traditional Parade Formation (a local folk art parade performance group) when preserving cultural artifacts. In addition, this study adopted the perspectives of museology and cultural artifact preservation to identify new ways to preserve religious objects (as opposed to simply storing them in museums). The author of this study referred to her own experience in artifact preserving at the Chao-Tian Temple as well as field research records obtained to propose a model for in situ artifact conservation. Assessments were made to determine whether this model can strengthen and solidify the history and knowledge transmission of local temples and preserve the local history, local culture, folk arts, and people’s memories of the Bei-Gang region in a complete and comprehensive manner. The various types of textile collections collected and stored by the Chao-Tian Temple over the years served as the sources of inspiration of this study. The religious functions and meanings given to these textile collections were used to examine the holiness and secularity of temples and religion-related objects, on the basis of which the following suggestion was made: by allowing the Chao-Tian Palace (a place with a wealthy collection of cultural artifacts) and local folk art parade performance groups to share the same ideology in artifact conservation, having the latter learn the artifact preservation methods utilized by the former, planning proper artifact preservation policies, and using artifacts or their cultural significance to link artifacts to local circles and related groups, the value of in situ artifact conservation will be higher than simply preserving them in museums for worship. In addition, by engaging in the aforementioned endeavors, the multidimensional qualities of cultural assets will be strengthened and solidified.

Painted-textiles are made of clothes and pigments, it is very sensitive to the changes of humidity and light, and also be damaged easily by mould. The painted textile object may consolidated by binding media in lining. In other words, it is important to choose the type of binding media and the way of application. In this study, non-water-soluble binding media : Polyvinyl butyral(PVB)and BEVA 371 film are chosen, which are usually used for consolidation in textile conservation treatments. Different environment will have different effects on properties of these binding media, therefore, accelerate ageing, including heat and humidity, light exposure and thermal ageing are given. These binding media will applied on the crepeline, to simulate treatment practicing. Analysis have shown that PVB is relatively stable than BEVA 371. It has less color changes than BEVA 371. In addition, it can also keep the silk out of the moisture but decrease the flexibility of textile. Experiments show that thermal ageing will result in chain breaking and produce aldehyde group in PVB. The weatherability of BEVA 371 is not as well as PVB, it can seep into the supporting layer easily under thermal environment , increasing peel strength of the textile. According to the results of degradation under various accelerate ageing experiments, it is suggested that before applying lining to the painted textile object, thoroughly examination of the textile and choose the appropriate material should be taken.

Full textLong term no-till (NT) farming can improve the CH4 oxidation capacity of agricultural lands through creation of a favorable soil environment for methanotrophs and diffusive gas transport. However, limited data is available to evaluate the merit of that contention. Although the potential for biological CH4 oxidation may exist in NT soils, restricted diffusion could limit expression of that potential in fine-textured soils. A study was conducted to assess the CH4 oxidation potential and gaseous diffusivity of soils under plow till (PT) and NT for > 50 years. Intact cores and composite soils samples (0-10 and 10-20 cm) were collected from NT and PT plots located at a well-drained site (Wooster silt loam) and at a poorly-drained (Crosby silt loam) site in Ohio. Adjacent deciduous forest soils were also sampled to determine maximum rate expected in undisturbed soils in the region. Regardless of study sites and soil depth, CH4 oxidation rate (measured at near ambient CH4) and oxidation potential (Vmax, measured at elevated CH4) were 3-4 and 1.5 times higher in NT than in PT soils, respectively. Activity in the NT soils approached (66-80 %) that in the forest soils. Half saturation constants (Km) and threshold for CH4 oxidation (Th) were lower in NT (Km: 100.5 µL CH4 L-1; Th: 0.5 µL CH4 L-1) than in PT soils (Km: 134 µL CH4 L-1; Th: 2.8 µL CH4 L-1) suggesting a greater affinity of long-term NT soils for CH4, and a possible shift in methanotrophic community composition. CH4 oxidation rates were lower in intact soil cores compared to sieved soils, suggesting that CH4 oxidation was limited by diffusion, a factor that could lead to lower field-measured CH4 uptake than suggested by biological oxidation capacity measured in the laboratory. Regardless of soil drainage characteristic, long-term NT resulted in significantly higher (2-3 times) CH4 diffusivity (mean: 2.5 x 10-3 cm2 s-1) than PT (1.5 x 10-3 cm2 s-1), probably due to improved soil aggregation and greater macro-pores volume in NT soils. Overall, these results confirm the positive impact of NT on the restoration of the biological (Vmax, Km and Th) and physical (diffusivity) soil attributes essential for CH4 uptake in croplands. Long-term implementation of NT farming can therefore contribute to the mitigation of CH4 emission from agriculture.
