Abstract:

The purpose of this paper is the digitization process and the techniques used, in cases of archival material preservation. Digitization as a process, whether it involves old documents and old maps, or audio and video clips, is the most appropriate process not only for the protection, but also for the reuse, upgrading and highlighting of cultural heritage elements. In this paper, the main problems are presented divided into the main categories of archival material (photographic material, printed material, audio, and video material) while at the same time the equipment and means used are presented.

Abstract:

The conservation of historic stone sculptures and buildings is a focus of research. But there are no completely satisfying protective materials until now. In this paper, a conservative film of apatite has been prepared on the surface-modified marble stone by using a solution of CaCl2 and (NH4)2HPO4 as the precursor through a biomimetic method. The prepared material was characterized by some instruments. Its performances were also evaluated by its ability to consolidate, resist soil and acid. The obtained results indicate that the conservative effects are satisfying and the biomimetic synthesis should represent a new prospective in stone conservation.

Abstract:

Virgin plastic pellets are widely used as raw materials in flexible plastic packaging which generate abundant postconsumer plastic waste. The widespread use of recycled plastic pellets as raw materials will reduce plastic waste generation significantly. However, substitution of virgin materials need high quality of recycled plastic pellets which produced from good quality of plastic waste. Design for material value conservation in this case study was a trial implementation of design principles of plastic bag in order to minimize its value degradation of plastic waste, and therefore increase its acceptance by plastic recycling industries. A Structural Equation Modelling (SEM) with Lisrel 8.8 software used as tool of analysis in evaluating consumer acceptance of the two types of design paradigm, current design and material value conservation based design. The results indicated that consumers accepted both type of packaging. With final standard factor loading, the proposed design indicated slightly better correlation coefficients: 0.46 for Ease of Information Delivery and 0.74 for Informational Content variables, better than current design with 0.44 and 0.73 coefficients. Widespread implementation of design for material value conservation will save virgin plastic consumption for plastic packaging production, reduce plastic waste generation as well as support material resource conservation in a better condition of environment. The social and economic benefit will also be obtained as multiplier effect of material value conservation.

Abstract:

Material value conservation (MVC) paradigm is an implementation of various approach, design principle, process or treatment of materials, and other efforts to minimize its value degradation and maximize its residual or salvage value, and therefore increase its utilization, life cycle, and the overall value. With design for material value conservation, a serial product utilization will exist in a serial lifetime. Design for material value conservation does not only need its evident of the benefit, but also needs integrated and structured stakeholder roles. For these purpose, properties of material testing and Interpretive Structural Modelling (ISM) implemented in this research. The positive effect of MVC implementation and a final result of ISM suggest an integrated stakeholder roles with appropriate linkage and interrelation of activities which support improvement of the quality of recycled plastic pellet and the material value conservation implementation success.

Abstract:

Impurity and contaminated waste of flexible plastic packaging will not be viable as raw materials for secondary recycling. This problem could be avoided by repetitive implementation of material value conservation through material purity protection since the product design activities up to the end of packaging life cycle. This paradigm also creates new sequential life cycles of products rather than once when only virgin materials were used as raw materials. With repetitive implementation of material value conservation and serial testing in a polymer laboratory, a type of virgin plastic pellet recycled up to the 8th stage of secondary recycling, and then the mechanical properties of materials tested according to the American Society for Testing and Materials (ASTM) standards. This research revealed that flexible plastic packaging materials that managed by Material Value Conservation (MVC) implementations were suitable for secondary recycling in producing the viable quality of recycled plastic pellets in mechanical properties measures, and leverage the potential of virgin plastic pellets utilization. Because of MVC implementations protected the purity of materials intensively, and then increased the value of recycled plastic pellets as raw materials for the new life cycle of plastic products.

Abstract:

Purpose This paper describes a system of collaboration between cultural institutions, conservation scientists and companies focussed on achieving global sustainability in museum and heritage sites through proactive conservation. The purpose of this paper is to propose the Proactive Collaborative Conservation (ProCoCo) as a viable tool to accomplish this objective. Design/methodology/approach The lack of degradation studies on contemporary materials, such as composites, was identified as an issue for the future of cultural heritage. Developing new approaches to heritage and conservation becomes vital and it is in this landscape that ProCoCo is inserted. A concise review of the literature is reported and the process that led to the development of ProCoCo is explained. Backcasting and forecasting were used to develop different parts of the approach. Findings ProCoCo consists in studying parameters of the new materials, manufactured by the commercial partner, then simulating the ageing and, finally, re-studying the same parameters in order to predict lifetime changes. During the case study, it was confirmed that such an approach helps in identifying weaknesses in the material, which can then become useful for conservators and manufacturers. Practical implications The approach allows conservation scientists and conservators to measure the conservation state of materials and to detect degradation at an early stage. Originality/value ProCoCo offers a different vision of the long-term issue of funding accessibility faced by museums and suggests a way of improving heritage global sustainability. It proposes a pragmatic and lasting solution to the insufficient public economic support in the arts which runs parallel to government aid.

Abstract:

Considering ancient monuments and historical buildings, it seems that these mortars have proved to be durable and reliable materials. The restoration and maintenance of old renders is one of the key aspects of correct rehabilitation practice. The ideal course of action is to replace the damaged material by a material with compatible characteristics.The study in development presents the chemical, physical and morphologic analysis performed for ancient air lime mortars belonging to historical monuments: Santa Marta Fortress in the coast line Lisbon-Cascais dated from XVII century and Defense Wall of Lisbon dated from XI century, which layout could be associated to roman period. It is important to underline that the studied samples of ancient portuguese air lime mortars, have been submitted during centuries to very severe maritime environment that includes daily cycles of wet/dry, wind, friction and the constant presence of salts, generally aggressive. However, they show very good performance and conservation state, unlike most of the new air lime mortars, which are generally considered weak, not very durable, materials. This work is included in a study intending to determine key factors to the durability of these ancient materials in presence of water. Visible reaction rims around some aggregates suggests the occurrence of pozzolanic reactions between aggregates and the lime binder that creates neoformation products, such as calcium-silico-aluminates, which seems be, besides the pores filling, the responsible for the resistance and cohesion of these ancient mortars submitted to aggressive humid environments.

Abstract:

AbstractThe information potential of human skeletal remains—as for any excavated material—is impacted by the conditions of archaeological burial, and the environments and actions experienced during subsequent excavation, laboratory processing, study, and storage. A conservation approach emphasizes the mitigation of threats to material stability and integrity, which for excavated collections are often most critical at the point of archaeological exposure and recovery. Conservation techniques involving application of modern synthetic materials for stabilizing skeletal remains in the field are discussed, using case examples primarily from terrestrial archaeological projects in Mesoamerica. The potential effects of the use of various conservation materials on results of biomolecular instrumental analysis are included.

Abstract:

In situ conservation is considered as conservation of wild biota in the natural habitat (locality). The authors extend the term to cultivated fruit species naturalised in the landscape, such as occasional spontaneous seedlings, and planted material such as old solitary trees among fields, old groves, avenues (country lanes), wind-breaks, and abandoned remnants of orchards. In situ conservation is also used to mark unique materials during collecting expeditions, before they will be taken as ex situ or proclaimed as permanent in situ. Important landraces found within 12 regions of the Czech Republic were registered, evaluated, and in situ localised by Global Positioning System (GPS). The following accessions were marked for in-situ conservation: apple (401), sweet cherry (263), pear (91), plum (42), sour cherry (27), and berry fruits (18).

Abstract:

Inappropriate plastic packaging design with excessive use of color and printing ink affected to the high cost of sorting, separation and cleaning, and low acceptance level of plastic waste for secondary recycling. This research proposed design for material value conservation which elaborated with a set of design criteria for rigid plastic packaging production as key solution in avoiding value degradation of the plastic waste. The existing design criteria of products have various approach which affected on how to manage abundant plastic waste with no or very low value of materials that has been generated by daily consumption of plastic packaging. Otherwise, the proposed design criteria conserve the material value systematically which make the post use materials of plastic packaging more financially feasible as raw materials in plastic recycling industry. Widespread implementation of the new design criteria in industry will generate broader impact and more benefits in economic, social and environment, especially for countries or regions with high density of people and high consumption rate of conserved products.

Abstract:

Flexible plastic packaging which rejected or with low acceptance as raw materials for secondary recycling need relevant evidence and explanation of its cause, and then, need a systemic solution on how to increase the acceptance level. Coloring and printing on flexible plastic packaging were predicted as the significant source of impurity that reduces the value of plastic material at the end of packaging life cycle. Otherwise, optimum use of label or sticker as printing media for informational and promotional purpose on the packaging proposed as a key solution in material value conservation. The existing practices which focused on how to manage abundant plastic waste generation, replaced by a new paradigm which focused on how avoid waste generation by conserving the material value systematically. This research revealed that flexible plastic packaging materials with no color pigment and no printing ink were suitable for secondary recycling to produce high quality of recycled plastic pellets and leverage the selling price. Therefore, labelling on the surface of packaging that protect purity of the material can be considered as one of methods in the implementation of material value conservation on flexible plastic packaging. Another benefits of the implementation of material value conservation are to improve the utilization of virgin plastic and its recycled plastic pellets as raw materials with better quality.

Abstract:

The study of material culture encompasses the material and the symbolic properties of things. Approaches based on an understanding of material culture can help with the conservation of textiles because they encourage considerations regarding changes in their properties, both material and symbolic, over time. Examples of textile conservation illustrate material culture in action to the extent that they analyze the challenges posed by garments deliberately concealed within buildings to conservation. The significance attributed to such textiles varies: some are valued as rare samples of clothing; others are appreciated for their protective function; while others are viewed as rubbish. The conservation strategies are indicated by the significance attributed to these textiles.

Abstract:

This paper presents the Scanning Electron Microscopy (SEM) observations conducted for the project "Heritage preservation and ethnobotany. Analysis of the influence of conservation treatment on genetic material comprised in historic herbaria“ (project no. 2014/13/N/HS2/03118) funded by the National Science Centre in Poland. The main aim of the project is to establish if treatment methods used by herbarium conservators and mounters in different countries are harmful for the DNA material comprised in herbarium specimens. In order to analyse this problem the author conducted an international survey among specialists with documented experience in herbarium treatment. The next step was the evaluation of the results and the choice of materials. The chosen materials were then applied to samples of herbarium specimens, artificially aged in the climatic chamber, and subjected to DNA analysis. The results of the survey illustrated the variety of the materials used to treat and mount specimens. Some of them, such as methyl cellulose, were used in different concentrations and different degrees of polymerization. The project limitations determined the selection of materials for further testing, particularly when it comes to the concentration of a particular adhesive/consolidant. At the same time the main assumption was to identify versions of the material that can effectively penetrate the specimen in order to intensify the potential influence on its DNA. Dessicated plant specimens are not a common material in conservation research because their structure is highly heterogenic, fragile and brittle. Moreover, the materials used for mounting and conservation treatment are most often adapted from bookbinding and paper conservation disciplines. They are not always suitable for the treatment of botanic material and may cause damage. When observations of stratigraphic samples under a traditional microscope proved unsatisfactory, the potential of SEM imaging was examined. SEM turned out to be a very useful tool to observe the effects of simulated conservation treatments conducted on herbarium specimen samples, but only when samples were coated with gold. The conclusions from these observations informed decisions about what versions of the conservation and mounting materials should be used for further testing. Additionally, some samples were observed after artificial aging in aclimatic chamber. It enabled us to observe the degradation of the layers of materials applied onto the specimens. The analysis focussed on the leaves of two species, Fragaria vesca (wild strawberry) and Arabidopsis thaliana (thale cress).

Preservation of our Historical Cultural Heritage built in stone requires studies on the material itself, on the environment where the monument is located, and even on the microclimate affecting a particular stone in the building. The knowledge of the decay processes, as well as mechanisms governing these processes, and the real effect of factors depending on the intrinsic properties of the material to be studied, and external agents of decay, will allow a rationale use of these materials and to anticipate their behaviour beforehand, in order to success in restoration

Abstract:

The influence of conservation compounds on maintenance of operation properties of equipment during a period of seasonal storage has been examined. It was found out that the use of conservation compounds allowed one to achieve maximum possible service life of equipment with minimum labor and material costs. The most widely-distributed types of conservation compounds (lubricants, oils, corrosion inhibitors, barrier materials, etc.), their application fields, the main advantages and disadvantages were analyzed.

Abstract:

Contaminated plastic waste if undergo a mechanical recycling process will have a low value. This can be overcome by repetitive implementation of Material Value Conservation (MVC) through material purity protection from design stage to the end of the material life cycle. Repetition of recycling up to eight times caused degradation of mechanical properties of plastics by up to 20%. The repetition was done on a laboratory scale with pure polypropylene as raw material. This research was conducted to overcome the degradation of plastic properties by mixing recycled plastic pellets with virgin plastic in the most optimal proportion. Plastic blends with certain compositions were recycled up to 8 times, then its mechanical properties are tested with the American Society for Testing Materials (ASTM) methods. This research revealed the opportunities to utilize the 6th recycled plastic pellets by mixing it with virgin plastic to improve its mechanical properties. Furthermore, this research shows that repetitive recycling of plastic blends with the implementation of material value conservation (MVC) could increase the value of recycled plastic pellets as raw materials and extend the life time of plastic materials.

Abstract:

Observation of stone deterioration using in situ,time-lapse microscopy techniques has revealed previously undescribed material behaviors that help to explain the destructive effects of several important processes in wall paintings, historic structures and monuments. It has long been acknowledged that cyclic stresses imparted by humidity changes, wet-dry cycling, and the crystallization and hydration of soluble salts, are important agents in the deterioration of these porous structures. The crystallization of salts is a particularly serious conservation problem (Arnold, 1975). Over time, cyclic salt crystallization results in the physical breakdown of the material (Goudie, 1993). Objects affected by such processes are often difficult to conserve since they are weak to begin with and the presence of salt inhibits the curing of some common conservation materials (Price and Kumar, 1994).Sodium sulfate is one of the most damaging of salts, apparently because it expands during the transition from the anhydrous phase (Na2SO4; thenardite) to the decahydrate form (Na2SO4•l0H2O; mirabilite).
