Book Description
Fruits are an important part of a balanced diet because of their high content in vitamins, minerals, dietary fiber, and bioactive compounds. Since the shelf life of fruits is limited due to microbiological, biochemical, and enzymatic reactions, processing and preservation are necessary to ensure food safety and year round availability. The present thesis aimed to investigate the effects of commonly used processing methods for fruit juice and puree production such as thermal pasteurization, alternative pasteurization (HPP, PEF), ultrasonication, and spray drying on the stability of carotenoids in goldenberry (Physalis peruviana L.) and orange (Citrus sinensis (L.) Osbeck). This thesis reveals the potential of ultrasonication as a homogenization technology that could be applied in the fruit juice industry in combination with pasteurization for the improved production of fruit juices and purees rich in potentially bioavailable carotenoids. Moreover, in comparison to commonly used carrier agents for spray drying, cellobiose showed a high potential for the application as innovative carrier material to obtain fruit juice powders with good physicochemical properties while preserving valuable constituents such as carotenoids.

Book Description
In 1858, Cyprian Clamorgan wrote a brief but immensely readable book entitled The Colored Aristocracy of St. Louis. The grandson of a white voyageur and a mulatto woman, he was himself a member of the "colored aristocracy." In a setting where the vast majority of African Americans were slaves, and where those who were free generally lived in abject poverty, Clamorgan's "aristocrats" were exceptional people. Wealthy, educated, and articulate, these men and women occupied a "middle ground." Their material advantages removed them from the mass of African Americans, but their race barred them from membership in white society. The Colored Aristocracy of St. Louis is both a serious analysis of the social and legal disabilities under which African Americans of all classes labored and a settling of old scores. Somewhat malicious, Clamorgan enjoyed pointing out the foibles of his friends and enemies, but his book had a serious message as well. "He endeavored to convince white Americans that race was not an absolute, that the black community was not a monolith, that class, education, and especially wealth, should count for something." Despite its fascinating insights into antebellum St. Louis, Clamorgan's book has been virtually ignored since its initial publication. Using deeds, church records, court cases, and other primary sources, Winch reacquaints readers with this important book and establishes its place in the context of African American history. This annotated edition of The Colored Aristocracy of St. Louis includes an introductory essay on African Americans in St. Louis before the Civil War, as well as an account of the lives of the author and the members of his remarkable family—a family that was truly at the heart of the city's "colored aristocracy" for four generations. A witty and perceptive commentary on race and class, The Colored Aristocracy of St. Louis is a remarkable story about a largely forgotten segment of nineteenth-century society. Scholars and general readers alike will appreciate Clamorgan's insights into one of antebellum America's most important communities.

Book Description
"In Electing Judges, James L. Gibson responds to the growing chorus of critics who fear that the politics of running for office undermine judicial independence. While many people have opinions on the topic, few have supported them with empirical evidence. Gibson rectifies this situation, offering the most systematic study to date of the impact of campaigns on public perceptions of fairness, impartiality, and the legitimacy of elected state courts-and his findings are both counterintuitive and controversial"--Page [four] of cover.

Book Description
Once a thriving metropolis on the banks of the Mississippi, St. Louis, Missouri, is now a ghostly landscape of vacant houses, boarded-up storefronts, and abandoned factories. The Gateway City is, by any measure, one of the most depopulated, deindustrialized, and deeply segregated examples of American urban decay. "Not a typical city," as one observer noted in the late 1970s, "but, like a Eugene O'Neill play, it shows a general condition in a stark and dramatic form." Mapping Decline examines the causes and consequences of St. Louis's urban crisis. It traces the complicity of private real estate restrictions, local planning and zoning, and federal housing policies in the "white flight" of people and wealth from the central city. And it traces the inadequacy—and often sheer folly—of a generation of urban renewal, in which even programs and resources aimed at eradicating blight in the city ended up encouraging flight to the suburbs. The urban crisis, as this study of St. Louis makes clear, is not just a consequence of economic and demographic change; it is also the most profound political failure of our recent history. Mapping Decline is the first history of a modern American city to combine extensive local archival research with the latest geographic information system (GIS) digital mapping techniques. More than 75 full-color maps—rendered from census data, archival sources, case law, and local planning and property records—illustrate, in often stark and dramatic ways, the still-unfolding political history of our neglected cities.
