Alternative containers for preserving peaches

Schoonenberg, Rolf January 1992 (has links)
Thesis (Masters Diploma (Food Technology)) -- Cape Technikon, Cape Town, 1992 / Kakamas peaches and Bulida apricots were heat processed in transparent and aluminium laminated plastic bags and compared with fruit heat processed in standard cans. Heat processing conditions were optimized to produce acceptable processed products. Appropriate chemical and microbiological properties of all treatments as well as sensory quality of peaches were investigated. Although rectifiable disadvantages such as texture softening and fading of colour appeared during storage, peaches and apricots were successfully heat processed in aluminium laminated pouches. Heat processed peaches had a maximum storage life of 12 months and apricots 6 months when stored at ambient temperature in aluminium laminated pouches.

Understanding a Historic Downtown as a “New” Vernacular Form: Immigrant Influence in Woodburn, Oregon

Larson, Julia 18 August 2015 (has links)
What does historic preservation mean in a historic downtown with a long-standing immigrant population? With 90% of the business owners in the historic downtown identifying as Latino, Woodburn, Oregon presents the convergence of historic preservation advocates and Latino business owners. Some stakeholders view historic preservation as maintenance to preserve what exists, while some view preservation as restoring a building to its build date aesthetics. This thesis addresses what the field of preservation and the stakeholders in Woodburn value and how that causes conflicts when dealing with preservation efforts. The main method employed for study in this thesis was collection of qualitative data through interviewing historic preservation advocates, city officials, and Latino business representatives. By understanding Woodburn as an example of a “new” vernacular form, the analysis explores how the community of Woodburn can negotiate its regional dynamics to create a local distinctiveness, which includes a many-layered historical narrative.

Invention And Contention: Identity, Place, And Memory Of The Spanish Past In The American Southwest, 1848-1940

Luna Lucero, Brian January 2013 (has links)
As the twentieth century unfolded, American writers, critics, and boosters presented a narrative of the arid Southwest as an exotic place blessed with a romantic history that could inspire, captivate and renew the many new white citizens flocking to rapidly growing cities. The history of Spanish colonialism in the area became a precious and exclusive cultural and economic resource. This dissertation tells the story of the commemoration of the Spanish past from 1848 to 1940 in three Spanish towns that grew into prominent American cities: Tucson, Arizona; Albuquerque, New Mexico; and San Antonio, Texas. In chapters centered on space, historic preservation, Mexican folk ritual, and pageants, this work examines the stories told about the Spanish past in these cities and reveals how people of differing classes and ethnicities gave meaning to the places they lived and to the process of American annexation of the region. That meaning shaped individual and social identities as well as the flow of power between them.

What Do We Mean by ‘Preserving Digital Information’? Towards Sound Conceptual Foundations for Digital Stewardship

Sacchi, Simone January 2015 (has links)
Digital preservation is fundamental to information stewardship in the 21st century. Although much useful work on preservation strategies has been accomplished, we do not yet have an adequate conceptual framework that articulates precisely and formally what preservation actually is. The intention of the account provided here is to bring us closer to this goal. Following an initial analysis of the concept of preservation as it occurs in ordinary discourse around digital stewardship, several influential preservation models are analyzed, identifying both useful insights and problems. A framework of interrelated concepts is then developed that analyzes the challenges of long term digital stewardship through the lens of information communication. Successful digital stewardship is understood as reliable, mediated, intentional communication with an emphasis on the agents involved in the process and the roles they play in supporting the intended flow of information through time and inevitable changes in the underlying mediating communication technology. The complex notion of the digital object, commonly considered the persistent unit of digitally–communicated information, is unpacked into its fundamental abstract and concrete components, avoiding the common category mistakes that pervade digital preservation discourse and impede a clear understanding of the nature of preservation. This conceptual framework makes use of the conceptual machinery of Situation Theory [Devlin, 1995] and the Gricean theory of meaning [Grice, 1957,Grice, 1968]. The notion of an interpretive frame [Dubin et al., 2011] is adopted here to model the contingent mapping between the fundamental components involved in the representation of information and extended with the notion of a constraint (from Situation Theory) to clarify the role of agent intentionality in the process of establishing the appropriate mappings that ultimately support the successful communication of units of information. This agent–based intentional perspective not only captures the social and contextual nature of successful digital stewardship, but also promises to support a finer grained analysis of preservation expectations from different stakeholders and the potential practical strategies to fulfill them. This research is intended as a contribution to the overall digital preservation agenda by bringing us closer to sound conceptual foundations for the long–term stewardship of our digital scientific and cultural heritage.

Preservation of ecosystems of international watercourses and the integration of relevant rules

Lee, Jing January 2012 (has links)
The unprecedented degradation of freshwater ecosystems due to the rampant exploitation of water resources re-establishes the importance of preserving freshwater ecosystems in order to ensure their continued viability that supports the attainment of sustainable development. This concern is addressed in Article 20 of the 1997 Watercourses Convention that specifically provides for the preservation of ecosystems of international watercourses. However, the interpretation and the subsequent application of this obligation are complicated by the proliferation of international instruments concerning the environment, which leads to the fragmentation of international law. In response to the apprehension raised over the undesirable consequences of the fragmentation of international law, the potential of Article 31(3)(c) of the 1969 Vienna Convention as an interpretative mechanism that enables the systemic integration of rules has come into the limelight. The objective of the present thesis, titled ‘Preservation of Ecosystems of International Watercourses and the Integration of Relevant Rules’ is to develop a interpretative framework for the operationalisation of Article 31(3)(c) that allows the full realisation of its potential as a tool of integration. A three-tier operationalisation framework that re-interprets the salient features of Article 31(3)(c) through the prism of an interactional understanding of international law is developed and executed through Chapters Two to Eight, where Chapter Nine provides a general conclusion of the thesis. The reconstruction of existing interpretation of Article 31(3)(c) provides a new understanding of this Article, which enables the realisation of its systemic integration potential. The application of this framework of operationalisation in the interpretation of the obligation to preserve ecosystems of international watercourses stipulated under Article 20 reflects contemporaneous development in international environmental law, and enhances the normative content and scope of Article 20.

Studies of Phormium tenax fibre prepared in the traditional Maori manner

Twose, Megan Frances, n/a January 1988 (has links)
Museum textiles provide priceless documentation of the activities of people throughout time. They record human interests and serve as resources for students of many disciplines. In New Zealand there are artefacts made from Phormium tenax which are extremely important in terms of providing a record of early New Zealand life and links to our past as both artistic and cultural symbols: they present an insight into the many faceted nature of early Maori culture. However there are some which are clearly in need of preservative treatment. Others may need care in the future for inevitably they are, or will be, subject to degradation during storage, when on display and during cleaning and refurbishing. Conservators, who embark occasionally on restorative treatments designed to reverse or arrest the symptoms of degradation, have begun to address the causes and future fundamental affects of their procedures. However there have been few scientific studies of the properties of the fibres and, therefore, there is little information to help the conservators in their tasks. This study has a twofold purpose. The first aim is to provide a short survey of the literature on Phormium and relate it to other lignocellulosic fibres. The emphasis in the survey is to put the conservation problem in context and to point to those technical articles which may be relevant to someone dealing with ancient materials. Secondly there is a practical study of the impact of heating the fibres in the absence and presence of oxygen and in water. These two agencies are ones which are directly relevant to the conservator.
