The aim of this thesis is to explore the evolving relationship between neighborhood change and public housing in the historically black neighborhood of Rosewood in Austin, Texas. In October 2010, the Housing Authority of the City of Austin was awarded a grant to begin the process of redeveloping one of the nation’s oldest federally funded public housing facilities – Rosewood Courts. As the once segregated public housing complex is slated for redevelopment, community members representing an assortment of interests have engaged in a series of heated exchanges and elevated discourse surrounding the legacy of public housing in Austin, Texas. At the same time, the Rosewood Neighborhood has witnessed a dramatic transformation in recent decades, losing much of its long-standing black community to an ever emergent gentrifying population. This research evaluates the relationship between neighborhood change and public housing (re)development, highlighting the position of Rosewood Courts within larger processes of policy and political economy transformation. / text

"The purpose of this study was to survey the cases of forty mentally retarded patients who have been presented by the Pre-parole Service to the Social Service Planning Staff of the Rosewood State Training School, Owings Mills, Maryland, from March through October 1959, in order to describe the differences--if any--on 18 selected items between the 28 retarded patients approved and the 12 disapproved for eventual return to the community. It was anticipated that such an analysis might more clearly define the term 'readiness for parole'"--Introduction. / Typescript. / "June, 1960." / "Submitted to the Graduate Council of Florida State University in partial fulfillment of the requirements for the degree of Master of Social Work." / Advisor: Merle M.

"The purpose of this study was to describe to a limited degree the characteristics of five patients of the Rosewood State Training School under consideration for discharge from the institution through the Community Adjustment Unit during December, 1958. It was believed that a case study of five patients would reveal some of the observable factors which may have influenced these five patients being ready for discharge. In addition, the five case illustrations descriptively present the function and procedures of one unit of the Social Services Department, Rosewood State Training School, Owings Mills, Maryland"--Introduction. / Typescript. / "June, 1959." / "Submitted to the Graduate Council of Florida State University in partial fulfillment of the requirements for the degree of Master of Social Work." / Advisor: Dorothy D.

Its essential oil is made up mainly of linalool, used as a fixative in perfumery. The byproducts of the rosewood extraction are generally employed as an energy source for heating boilers in their own plants. These byproducts contain substances with high potencial for use as biobased. The present work aims to study the byproducts of extraction of Aniba rosaeodora Ducke essential oil to enable a better understanding of the metabolites found in the byproducts, as well as better use of raw material by industry. Branches and leaves of Aniba rosaeodora were collected in the Reserva Ducke. The solid and liquid byproducts of industrial oil extraction of A. rosaeodora were obtained in partnership with Magaldi Agro Industrial Ltda. The collected branches were submited to six different methods of alkaloids extraction. Among then, three were selected due the yield obtained, the quality and the practicality of the methods. These three selected methodologies were applied to the industrial solid byproducts. The alkaloidal fracions obtained were analysed by mass spectrometry to compare the alkaloidal profiles. The liquid byproducts were centrifuged to obtain the oily fractions, which were analysed by gas chromatography coupled to flame ionization detector and a mass spectrometer. An aliquote of hydrolate was lyophilized and another aliquote was subjected to experiments with XAD-4 resin, in order to obtain concentrated fractions of organic substances present in hydrolate. These samples were analysed by mass spectrometry in a similar way to alkaloidal fractions obtained of solid byproducts. The chemical alkaloidal profiles obtained by mass spectrometry of alkaloid fractions showed peaks consistent with the alkaloids anibine, duckein and reticuline. Others peaks detected were consistent with coclaurine, N-methylcoclaurine, boldine and norboldine, already reported in Lauraceae. Among the alkaloids detected, the anibine, reticuline and N-methylcoclaurine were observed with higher relative abundance in the mass spectra. The oily fractions obtained from hydrolates showed constituents in common with the essential oil, with differences in the concentrations of these substances. The oily fractions showed linalool as majoritary substance, besides the α-terpineol and geraniol. The fractions obtained from lyophilized hydrolates and XAD-4 resin experiments showed complex composition, suggesting the presence of several substances. Some of alkaloidal fractions obtained from industrial byproducts have shown promise in relation to cytotoxic activity. There were also observed antimicrobial activity of alkaloidal fractions obtained from industrial byproducts and anibine against Bacillus subtilis. The results showed that the byproducts present the same alkaloids found in A. rosaeodora, indicating that the industrial extraction of the essential oil did not cause significant degradation of these molecules. Thus the byproducts of extraction of A. rosaeodora essential oil can be potencial sources of new products, promoting the best use of raw material. / A família Lauraceae destaca-se por apresentar espécies com grande importância econômica, dentre elas Aniba rosaeodora Ducke, utilizada na extração de óleo essencial. Seu óleo essencial é formado majoritariamente por linalol, utilizado como fixador na perfumaria. Os subprodutos da extração do pau-rosa são geralmente empregados como fonte de energia para o aquecimento das caldeiras nas próprias usinas. Estes subprodutos contêm substâncias com grande potencial de aproveitamento como bioprodutos. O presente estudo tem como objetivo estudar os subprodutos da extração do óleo essencial de Aniba rosaeodora Ducke a fim de possibilitar um maior conhecimento dos metabólitos encontrados nos subprodutos, assim como um melhor aproveitamento da matéria prima utilizada pela indústria. Galhos e folhas de Aniba rosaeodora foram coletados na Reserva Ducke. Os subprodutos sólidos e líquidos da extração industrial do óleo essencial de A. rosaeodora foram obtidos em parceria com a Magaldi Agro Industrial Ltda. Os galhos coletados foram submetidos a seis metodologias diferentes de extração de alcaloides. Dentre estas, três foram selecionadas devido aos rendimentos obtidos, a qualidade das frações e a praticidade dos métodos. As três metodologias selecionadas foram aplicadas ao subproduto sólido industrial. As frações alcaloídicas obtidas foram analisadas por espectrometria de massas para a comparação dos perfis alcaloídicos. Os subprodutos líquidos foram centrifugados para a obtenção das frações oleosas, as quais foram analisadas por cromatografia em fase gasosa acopladas a detectores de ionização de chamas e espectrômetro de massas. Uma alíquota do hidrolato foi liofilizada e outra foi submetida a experimentos com resinas XAD-4, visando à obtenção de frações concentradas das substâncias orgânicas presentes no hidrolato. Essas amostras foram analisadas por espectrometria de massas de forma similar às frações alcaloídicas obtidas do subproduto sólido industrial. Os perfis químicos obtidos por espectrometria de massas das frações alcaloídicas mostraram picos compatíveis com os alcaloides anibina, duckeina e reticulina, já relatados nesta espécie. Outros picos detectados foram compatíveis com coclaurina, N-metilcoclaurina, boldina e norboldina, que já são relatados em Lauraceae. Dentre os alcaloides detectados, a anibina, reticulina e N-metilcoclaurina foram observados com maior abundância relativa nos espectros de massa. As frações oleosas obtidas dos hidrolatos mostraram constituintes em comum com o óleo essencial, com diferenças nas concentrações dessas substâncias. As frações oleosas apresentaram o linalol como substância majoritária, além do α-terpineol e geraniol. As frações obtidas do hidrolato liofilizado e do experimento com a resina XAD-4 mostraram-se complexas, sugerindo a presença de diversas substâncias. Algumas das frações alcaloídicas obtidas dos subprodutos industriais mostraramse promissoras em relação a atividade citotóxica. Foi observada também atividade antimicrobiana das frações alcaloídicas obtidas do subproduto industrial e da anibina frente ao Bacillus subtilis. Os resultados obtidos mostraram que os subprodutos apresentam os mesmos alcaloides encontrados na espécie A. rosaeodora, indicando que a extração industrial do óleo essencial não causa degradação significativa dessas moléculas. Sendo assim os subprodutos da extração do óleo essencial de A. rosaeodora podem ser possíveis fontes de novos produtos, promovendo o melhor uso da matéria prima.

This paper investigates chemical bleaching of wood and its ageing to make specie specific recommendations on which bleaching solutions to use when color adjusting veneer for furniture restoration.  In more detail, chemical bleaching of European walnut (Juglans regia), Rio rosewood (Dalbergia nigra), purpleheart (Peltogyne spp.), Honduras mahogany (Swietenia macrophylla) and padauk (Pterocarpus spp.) has been investigated using eleven different bleaching solutions. Both oxidative (e.g. hydrogen peroxide and potassium permanganate) and reductive (e.g. oxalic acid and sodium bisulfite) solutions have been used. Furthermore, to investigate aging of the bleached surfaces they were subjected to sunlight behind a glass window until a change in Blue Wool Scale 3 was obtained. Visual examination has been used to rank the color change after the chemical bleaching and the sun light exposure experiment. A small color change after the sun light exposure experiment indicates a high degree of lightfastness and is preferred for long term stability when restoring furniture. The results show that the wood species react in different ways to the investigated bleach solutions and to sun light exposure. It can also be noted that all investigated solutions were not suitable for all wood species. Moreover, the sun light exposure experiment identified effective bleach solutions that gave an unacceptable low lightfastness for mahogany and padauk after chemical bleaching. Based on the chemical bleaching and sun light exposure results, preferred bleaching solutions are recommended for the investigated wood species. / En vanlig restaureringsuppgift är att ställvis ersätta borttappat träfaner på en möbel. Originalfaneret har blekts med tiden, varför det nya faneret ofta är för färgstarkt och färgen behöver reduceras. När vi upplever en bit padouk som intensivt röd eller amarant som lila, beror det på att det i trät finns ämnen som tar upp energi motsvarande energin i våglängder av synligt ljus. När ämnena absorberar en del av det synliga ljuset registrerar våra näthinnor att de saknas, vilket tolkas som en färg av vår hjärna. De ämnen som absorberar synligt ljus kan brytas ner av solljus över längre tid eller på några minuter genom tillförseln av ett oxidations- eller reduktionsmedel. I mitt examensarbete undersöker jag hur olika oxidations- och reduktionsmedel bleker olika träslag. Jag har valt att undersöka hondurasmahogny, europeisk valnöt, brasiliansk jakaranda, padouk och amarant, då det är träslag som ofta behöver blekas när de används i kompletteringar. Vidare undersöker jag hur den genom blekning erhållna färgen i trät i sin tur påverkas av solljus. Detta är viktigt för att förstå hur de restaurerade delarna på möbeln kommer att åldras. De viktigaste resultaten sammanfattas nedan: Valnöt, jakaranda och amarant reagerade på liknande sätt vid kemisk blekning med de i studien använda lösningarna. De blekas mest av natriumhydroxid och salter med väteperoxid. Mahogny och padouk reagerade på liknande sätt vid kemisk blekning. De blektes mest, med ett jämnt resultat, av väteperoxid med natriumhydroxid eller ammoniak. Oxidationsmedel blekte effektivare än reduktionsmedel. Enbart väteperoxid gjorde jakaranda mörkare. En hög ammoniakkoncentration gav blekare resultat än en låg på alla träslag utom amarant. Valnöt var mest ljusäkta av de undersökta träslagen. Majoriteten av mahognyproverna mörknade av solljusexponeringen. Jakaranda och padouk blektes av solljusexponeringen. Flertalet amarantprover mörknade och ett mindre antal blektes av solljusexponeringen. Solljusexperimentet identifierade blekningslösningar som gav oacceptabelt låg ljusäkthet på mahogny och padouk.   För effektiv blekning och godtagbar ljusäkthet rekommenderas följande lösningar för respektive träslag. Välj lösning beroende på önskad blekningsgrad (se Tabell 2 sid 10). Mahogny: väteperoxid, oxalsyra eller kaliumpermanganat och natriumbisulfit. Valnöt: väteperoxid med eller utan ammoniak, väteperoxid och natriumhydroxid med eller utan salter eller natriumbisulfit och oxalsyra. Jakaranda: väteperoxid med ammoniak, oxalsyra, väteperoxid och natriumhydroxid med eller utan salter, natriumbisulfit och oxalsyra eller kaliumpermanganat och natriumbisulfit. Padouk: natriumhydroxid, natriumsilikat och kalciumhydroxid följt av väteperoxid. Amarant: väteperoxid med eller utan ammoniak, väteperoxid och natriumhydroxid med eller utan salter eller kaliumpermanganat och natriumbisulfit.
