The importance of vernacular architecture and historical treatments in the contemporary city
No full textNão é possível fazer uma avaliação do patrimônio histórico somente por meio de valores estéticos; o desenho e os símbolos da cidade também se tornam memória na medida em que adquirem uma dimensão coletiva: é necessário considerar a importância da edificação como característica de um processo de reconhecimento do lugar e não da capacidade do seu autor. A cidade resulta das relações que cada elemento estabelece com todos os outros, da existência de traçados históricos e de edificações capazes de manter e traduzir a memória histórica do lugar, também e principalmente com aqueles espaços imateriais, como os vazios urbanos, ou com edifícios industriais, pois eles marcam o território. Técnicas de expansão urbana foram substituídas na Europa por práticas de recuperação e remodelação fundamentadas na história, por meio de significados coletivos, intrínsecos e estratificados, ou seja, baseados nas tradições regionais e pertencentes à cultura popular. Esta se manifesta de modo muito diferente em cada região, em função de suas raízes, costumes e identidade. Para exemplificar esse fenômeno, foram selecionadas duas situações de recuperação arquitetônica em Milão que se desenvolvem em duas escalas de interferência urbana diferentes, considerando em ambos os casos os efeitos de re-equilíbrio e impacto no entorno; um edifício de arquitetura vernacular com fortes relações com o entorno, cuja localização é central, e uma área extensa de obsolescência industrial de forte impacto urbano localizada em área periférica.It is not possible to make an assessment of the historical patrimony only by means of esthetical values; the design and the symbols of a city also become part of its memory as they acquire a collective dimension; it is necessary to consider the importance of the buildings as a characteristic of a process of knowing the place and not the skill of its author. The city is the result of the relationships that each element establishes with all the others, of the existence of a historical heritage and of buildings able to maintain and translate the historical memory of the place, also and mainly with those immaterial spaces, as the urban emptiness, or with industrial buildings, because they mark the territory. Urban expansion techniques were substituted in Europe by recuperation and remodeling practices based on History, by means of collective, intrinsic and stratified meanings; that is, based on the regional and collective traditions belonging to popular culture. This culture manifests itself in very different ways in each region, as a function of its roots, habits and identity. To exemplify this phenomena, two situations of architectural recuperation in Milan were selected that develop in two different scales of urban interference. In both cases the effects of re-equilibrium and impact on their surroundings were considered; a building of vernacular architecture with strong relationships with its surroundings in a central location, and a large area of industrial obsolescence with a strong urban impact situated in a peripheral area
SRD5A3 is required for converting polyprenol to dolichol and is mutated in a congenital glycosylation disorder.
No full textN-linked glycosylation is the most frequent modification of secreted and membrane-bound proteins in eukaryotic cells, disruption of which is the basis of the congenital disorders of glycosylation (CDGs). We describe a new type of CDG caused by mutations in the steroid 5a-reductase type 3 (SRD5A3) gene. Patients have mental retardation and ophthalmologic and cerebellar defects. We found that SRD5A3 is necessary for the reduction of the alpha-isoprene unit of polyprenols to form dolichols, required for synthesis of dolichol-linked monosaccharides, and the oligosaccharide precursor used for N-glycosylation. The presence of residual dolichol in cells depleted for this enzyme suggests the existence of an unexpected alternative pathway for dolichol de novo biosynthesis. Our results thus suggest that SRD5A3 is likely to be the long-sought polyprenol reductase and reveal the genetic basis of one of the earliest steps in protein N-linked glycosylation
Bixin Extraction From Defatted Annatto Seeds
No full textBixin is the major carotenoid in the seed of the Annatto plant (Bixa orellana L.). The aim of this study was to obtain extracts containing bixin from seeds that had been partially defatted by supercritical fluid extraction. Pressurized liquid extraction (PLE) and low-pressure solvent extraction (LPSE) methods were used, and the effects of the solvent, temperature, pressure, solvent mass to feed mass (S/F) ratio and ultrasonication were evaluated for the global yield (X0(%)) and the bixin yield (BY(%)). Extraction conditions producing high yields of bixin were established for both the PLE and LPSE methods. Analysis of variance was used to examine the influence of the individual extraction variables in LPSE and PLE. For LPSE; significant effects were found for solvent, temperature, and the interactions of temperature with solvent and temperature with S/F. Solvent was the only variable that significantly affected X0(%) and BY(%), for PLE. While ultrasonication did not significantly affect X0(%) or BY(%), scanning electron microscopy analysis revealed structural changes in the vegetal matrix following this treatment. © 2013 Académie des sciences.173268283(2006) Joint FAO/WHO Expert Committee on Food Additives, Compendium of Food Additive Specifications, 67th MeetingBarrozo, M.A.S., Santos, K.G., Cunha, F.G., (2013) Ind.

The Japanese in Hawaii : an annotated bibliography of Japanese Americans
No full textRevised by Dennis M. Ogawa with Jerry Y. Fujioka ; supported by the Japanese American Research Center (JARC).The Japanese-American experience in Hawaii spans over one hundred years and encompasses four generations— the issei (first generation), nisei (second), sansei (third), and yonsei (fourth). Compared to the small contingent of less than 150 immigrants who arrived in Honolulu in 1868, Japanese Americans today constitute a substantial portion of the Island population, numbering over 217, 000. Like all of Hawaii's ethnic groups, the experience of the Japanese Americans lends itself to a variety of historical and cultural studies. Researchers from within and without the ethnic group have explored this experience creatively and from a wide range of viewpoints. As a consequence, interpretations regarding the day-to-day affairs, community activities, generational characteristics, and cultural philosophy of the people as a whole have been extremely varied. Due to this diversity, the existing studies on Hawaii's Japanese Americans present a rich background of information that stimulates comparative ethnic perspectives and leads to a greater understanding of the processes of human behavior in the Islands.
This revision of Mitsugu Matsuda's Japanese in Hawaii, 1868-1967: An Annotated Bibliography of the First Hundred Years calls attention to writings which are available to students and individuals interested in Americans of Japanese ancestry. The materials range from scholarly pieces based upon traditional academic sources for documentation to literature found in newspapers, novels, and general periodicals which have historic, biographic or general descriptive value.
The primary purpose of this bibliography is to provide a reference guide for the undergraduate, English-speaking student who is attempting to understand the Japanese-American experience in Hawaii. Consequently, two criteria were established for the listing of materials in this work. First of all, it was felt that a usable guide include only those materials which were in English. However, Japanese language entries from Matsuda's original work were reprinted in the Appendix for researchers who may find such information valuable. Second, writings were selected based on their general availability. Obscure manuscripts, private papers, or articles appearing in journals not available to students were omitted. This bibliography does not pretend to be exhaustive of the wealth of materials written by, for, or about Japanese Americans, but does provide a complete reference of published studies which can be readily obtained.
While this work is largely an update and reorganization of Matsuda's annotated bibliography, certain additions and changes have been made so as to fulfill the objective of providing a useful reference guide for students. The first change was to bring Matsuda's work on English publications up-todate. To add to student usability, a much-needed subject index was developed incorporating both new and old materials. Further, all entries were organized alphabetically by author rather than following Matsuda's original categorization of materials into separate resource headings.
Also included in this publication were selected entries from Judith Rubano's bibliography Culture and Behavior in Hawaii (No. 3 in the Hawaii Series). Rubano's work is an excellent compilation of behavioral science materials but too broad and inclusive for students seeking references solely on Japanese Americans. Consequently, where applicable, this work has been integrated into the present bibliography. Annotations taken from the Matsuda and Rubano bibliographies are followed by the letter designation [M] or [R] and the entry number of the original work
The Chinese in Hawaii; an annotated bibliography
No full textThis bibliography lists and annotates selected materials with significant data on the Chinese in Hawaii without regard to academic field or orientation. Its primary aim is to aid the researcher in locating data on the Chinese— much of which is scattered in a myriad of short articles and brief documents. While emphasis is on the Chinese in the Hawaiian Islands, selected references on the homeland are included to provide background on emigration and the effects of such emigration on the home country.
In the process of locating materials for inclusion in this bibliography, I relied heavily upon other bibliographic works— especially previous publications in the Social Science Research Institute Hawaii Series: The Japanese in Hawaii, 1868-1967: A Bibliography of the First Hundred Years, by Mitsugu Matsuda; The Koreans in Hawaii: An Annotated Bibliography by Arthur L. Gardner; and Culture and Behavior in Hawaii: An Annotated Bibliography by Judith Rubano. A number of annotations from these works were quoted in their entirety or with slight modification. Where this was done, the author of the bibliography and the number of the item quoted follows the annotation. Also very useful were English in Hawaii: An Annotated Bibliography, co-authored by Stanley Tsuzaki and John Reinecke (1969) and two SSRI working papers: "The Chinese in Hawaii: A Selected and Annotated Bibliography" by C. H. Lowe and "The Filipinos in Hawaii: An Annotated Bibliography" by Ruben R. Alcantara and Nancy S. Alconcel, with Cesar S. Wycoco.
Materials on the Chinese in Hawaii were searched at public libraries throughout Honolulu. A search of libraries on the other Islands or on the mainland United States may yield further data, but is beyond the scope of this project. The location of each work cited is indicated at the extreme right of the entry, preceding the annotation. Additional locations of general materials have been omitted if they are available on the University of Hawaii campus; in the case of rare documents all possible locations are listed.
The most extensive collection of works is found at the Hawaiian and Pacific Collection of the University, but important documents are also held by the Hawaii Chinese History Center, the Hawaiian Historical Society, the Hawaiian Mission Children’s Society, the Archives of Hawaii, and the Hamilton Library of the University of Hawaii. B. A. honors’ theses are housed separately on the fourth floor of Sinclair Library at the University, but selected theses are currently being Xeroxed for inclusion in the Hawaiian and Pacific Collection. Some materials are also available at the Hawaii State Library, the Chinese Chamber of Commerce, the United Chinese Society, the University of Hawaii Asia Collection and various State offices, such as the Department of Land and Natural Resources. Limited information on the Chinese is housed at the ILWU and Hawaiian Sugar Planters Association (HSPA) libraries, but since these libraries are not open to the general public, their materials are not reported in this bibliography. Holdings of the Bernice Pauahi Bishop Museum duplicate University materials, and thus the museum location is not reported.
Newspaper articles reporting current news on the Chinese are excluded. Regular news articles are indexed in the Index to the Honolulu Advertiser and Honolulu Star Bulletin, 1929-1968, published in 1968 by the Office of Library Services of the Hawaii Department of Education. The Archives of Hawaii has indexed a number of Hawaii newspapers, although the indexing is incomplete. However, special articles such as the 1961 supplements to the Honolulu Star Bulletin and Honolulu Advertiser commemorating the fiftieth anniversary of the Chinese Chamber of Commerce, are listed.
Materials on the Chinese on the mainland United States are purposely omitted as these have been covered elsewhere. Three useful bibliographies of Asians on the mainland U. S. are: Asians in America: A Bibliography of Master's Theses and Doctoral Dissertations by William Wong Lum (1970); Asians in America: A Selected Annotated Bibliography by Isao Fujimoto, Michiyo Yamaguchi Swift and Rosalie Zucker (1971); and Asian Americans: An Annotated Bibliography, Harry Kitano, ed. (1971). The Hawaii Chinese History Center has collected a large amount of printed materials from various organizations in Honolulu. For many organizations these documents consist of minutes, financial records, and other raw data retained by the present officers. Those interested in such materials can consult the list of "Presidents of the Chinese Organizations in Honolulu, " issued annually by the United Chinese Society, and then contact the current president.
Chinese-language sources are included in the body of this bibliography in alphabetical order according to the English translation of the author or title of the article. The Chinese characters for these sources are listed by item number in the Glossary. This bibliography represents the culmination of a two-year cooperative effort of the Hawaii Chinese History Center and the Social Science Research Institute of the University of Hawaii, and is the first major publication produced by the Hawaii Chinese History Center, an organization initiated in October, 1971
Efecto in vitro del aceite de girasol (Helianthus annuus L.) sobre ácido transvacénico y patrón de ácidos grasos de cadena larga en la digesta rumina
No full textThe addition of vegetable oils rich in long chain fatty acids (LCFA) to ruminant diets has been proposed as an alternative to reduce methane (CH4) and increase levels of conjugated linoleic acid (CLA) in milk and meat, that is preceded by the production of transvacenic acid (TVA) in the rumen. The objective of this study was to evaluate the effect of the supplementation of sunflower oil in proportions of 0%, 1% and 3% (DM bases) to in vitro fermentation substrates (gas production technique):Pennisetum clandestinum or Lolium perenne, on the kinetics and total gas production, CH4 production, concentration of volatile fatty acids (VFA), production of CLA and TVA and the pattern of long chain fatty acids (LCFA). Addition of sunflower oil (1% and 3%) did not decrease gas production (A) or gas production rate (c); however, it increased the time delay to start fermentation (L, 0.042, 0.425 y 0.564 h for control, 1% y 3%, respectively; P<0.001). Oil addition also did not reduce production of CH4. Nevertheless, it slightly increased the percentage of propionic acid (22, 22.5 y 22.6% for control, 1% y 3%, respectively; P<0.05). The proportion of conjugated linoleic acid (CLA) did not change because of the supplementation of oil, but the proportion of transvacenic acid (TVA) increased significantly in response to the addition of oil (13.4, 16% y 21.8% for control, 1% y 3%, respectively; P<0.01). The inclusion of sunflower oil at levels of 1 and 3% of the dry matter increased ruminal production of TVA without affecting negatively the variables that characterize the ruminal fermentation.La adición de aceites vegetales ricos en ácidos grasos de cadena larga (AGCL) a las dietas para rumiantes se ha propuesto como alternativa para disminuir las emisiones de metano (CH4) y aumentar los niveles de ácido linoleico conjugado (ALC) en la leche y la carne, que está mediado por la producción a ácido transvacénico (ATV) en el rumen. El objetivo de este estudio fue evaluar el efecto de la adición de aceite de girasol en proporciones de 0%, 1% y 3% (con base en MS) a substratos de fermentaciónin vitro (técnica de producción de gas): pasto Kikuyo (Pennisetum clandestinum) o pasto Ryegrass (Lolium perenne), sobre la cinética de producción de gas, la producción de CH4, la concentración de ácidos grasos volátiles (AGV), la producción de ALC y ATV y otros ácidos grasos de cadena larga (AGCL). La adición de aceite de girasol (1% y 3%) no disminuyó la producción de gas (A) ni la tasa de producción de gas (c); sin embargo, sí aumentó el tiempo de retardo en el inicio de la producción de gas (0,042, 0,425 y 0,564 h para control, 1% y 3%, respectivamente; P<0,001). La adición de aceites tampoco redujo la producción de CH4. No obstante, la adición de aceite incrementó ligeramente el porcentaje de ácido propiónico (22,0, 22,5 y 22,6% para control, 1% y 3%, respectivamente; P<0,05). La proporción de ácido linoleico conjugado (ALC) no varió como consecuencia de la adición de aceite, pero la proporción de ácido transvacénico (ATV) sí se incrementó significativamente en respuesta a la adición el aceite (13,4, 16% y 21,8% para control, 1% y 3%, respectivamente; P<0,01). La inclusión de aceite de girasol a niveles del 1 y 3% sobre la materia seca aumentó la producción de ATV a nivel ruminal sin afectar negativamente las variables que caracterizan la fermentación ruminal
