Bakers and Basques
Mexico City’s colorful panaderías (bakeries) have long been vital neighborhood institutions. They were also crucial sites where labor, subsistence, and politics collided. From the 1880s well into the twentieth century, Basque immigrants dominated the bread trade, to the detriment of small Mexican bakers. By taking us inside the panadería, into the heart of bread strikes, and through government halls, Robert Weis reveals why authorities and organized workers supported the so-called Spanish monopoly in ways that countered the promises of law and ideology. He tells the gritty story of how class struggle and the politics of food shaped the state and the market. More than a book about bread, Bakers and Basques places food and labor at the center of the upheavals in Mexican history from independence to the aftermath of the Mexican Revolution.
Rubbers in Contact with Food
This report provides an excellent, clearly written report on the state-of-the-art of food contact elastomers. In the UK, the Ministry of Agriculture Fisheries and Food (MAFF), industry and Rapra have combined forces to study the issues surrounding rubbers in contact with food. A survey has been carried out of the food processing industry to determine which rubber products come into contact with food, contact area, duration of contact and temperature of contact. The results of this survey are found in the report and a compilation of data tables on each food industry studied is included as an appendix. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.
Rubber Product Failure
Rubber components are used in many demanding applications, from tyres and seals to gloves and medical devices, and failure can be catastrophic. This review of Rubber Product Failure outlines and illustrates the common causes of failure, while addressing ways of avoiding it. There has been increasing pressure to improve performance so that rubbers can be used at higher temperatures and in harsher environments. For example, the under-the-bonnet temperature has increased in some vehicles and new medical devices require longer lifetimes in potentially degrading biological fluids. The expectations of tyre performance in particular are increasing, and retreads have been in the spotlight for failur...
Failure of Polymer Products Due to Thermo-oxidation
The combined effects of oxidising media and heat result in degradation by thermo-oxidation. The principles and cases described in this review emphasise long term degradation in service. Two additional phenomena that influence thermo-oxidation are also described: catalysis by certain metal ions, and the influence of stress. An additional indexed section containing several hundred abstracts from the Polymer Library gives useful references for further reading.
Emulsion Polymerisation and Latex Applications
The term latex covers emulsion polymers, polymer dispersions and polymer colloids. This review report provides a general overview of the emulsion polymerisation processes and explains how the resulting latices are used in industrial applications. The classes of emulsion polymers are surveyed and the commercial technologies and potential future uses discussed. An additional indexed section containing several hundred abstracts from the Polymer Library gives useful references for further reading.
Plastics Profile Extrusion
This review describes the changes in the industry over the last 5 years, concentrating on the screw extrusion process where the extruded product has a constant cross-section. Film and sheet production and pultrusion are not included in this review. Products and applications are reviewed in detail and major advances such as computer control, materials and speed and size issues are also covered. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database provides useful references for further reading.
Polymers in Building and Construction
This review outlines the nature, culture and trends in the building and construction industry. It describes the current building and construction market place and the applications and potential for the wide range of polymer materials available today. This review is accompanied by indexed summaries of papers from the Rapra Polymer Library database to allow the reader to search for information on specific topics.
Health and Safety in the Rubber Industry
This report takes a broad overview of the rubber industry and highlights the key concerns over safety that are currently being raised. The statistics on the incidence of accidents are reviewed. The rubber industry has been highlighted as having a higher rate of accidents than other similar industries. Measures that can be taken to avoid injury from machinery are discussed, including advice from the International Labour Organization on mill safety. The review is accompanied by around 400 abstracts from the Rapra Polymer Library database, to facilitate further reading on this subject.
Emissions from Plastics
This report outlines the key issues regarding emissions from plastics. The report covers emissions from plastics during processing, treatment, storage and end-use. It summarises the published research on a wide variety of materials and settings. New methods of analysis and testing have been developed or adapted to examine these emissions. This report discusses the main techniques used. Data from analysis work on air quality and emissions from plastics is also included in this report. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.
Rubber Mixing
This report describes the current state of the art in mixing in the rubber industry from a practical and essentially technological viewpoint. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database provides useful references for further reading.
