Community Organization, Participation, and Interaction in Renewal Areas of Detroit

This study attempts to examine community group relationships as manifested in the intersection of organized community groups actively involved in, and being themselves affected by urban renewal activities within two Detroit neighborhoods. Basic to this examination is the necessity for understanding the various organizational units making up the community groups commonly found in renewal activities and their functions within such development programs. Background is provided for adequate understanding of such groups by outlining how and under what circumstances community organizations are formed, the effect of their orientation and point of view on inter-group cooperation and the factors that shape community group interaction and give rise to community controversy. It is recognized that urban renewal programs may utilize a combination of differing approaches involving lay group participation to foster general citizen involvement. Therefore, two methods of renewal treatment, redevelopment and neighborhood conservation, are examined from the standpoint of community group interaction on a specific topic of controversy. Using a comparative analysis approach, the basic purpose of this study is to determine significant differences, uniformities, and patterns of behavior of key group organizations relating to, and interacting on a controversial community issue and their impact on the urban renewal administrative process

17α-Ethynyl-5α-androstane-3α, 17β-diol Treatment of MNU-Induced Mammary Cancer in Rats

N-methyl-N-nitrosourea (MNU) induces estrogen-dependent mammary tumors in female Lewis rats. We explored the antineoplastic activity of a synthetic androstane derivative, 17α-ethynyl-5α-androstane-3α, 17β-diol (HE3235), as a single agent or in combination with docetaxel compared to tamoxifen, anastrazole, and docetaxel monotherapies against MNU-induced mammary tumors in female Lewis rats. Treatment with HE3235 alone rapidly reduced tumor burden, similar in effect to tamoxifen and anastrozole. The combination of HE3235 with docetaxel was more effective than any single agent, although without apparent toxicity. Only HE3235 or HE3235 plus docetaxel continued to suppress tumor growth after cessation of treatment. HE3235 treatment increased immunohistochemical markers of apoptosis and expression of proapoptotic genes and estrogen receptor beta and decreased expression of antiapoptotic genes, androgen receptor, and estrogen receptor alpha. These data warrant clinical investigation of HE3235 for breast cancer treatment

Report of the Topical Group on Dark Energy and Cosmic Acceleration: Complementarity of Probes and New Facilities for Snowmass 2021

The mechanism(s) driving the early- and late-time accelerated expansion of the Universe represent one of the most compelling mysteries in fundamental physics today. The path to understanding the causes of early- and late-time acceleration depends on fully leveraging ongoing surveys, developing and demonstrating new technologies, and constructing and operating new instruments. This report presents a multi-faceted vision for the cosmic survey program in the 2030s and beyond that derives from these considerations. Cosmic surveys address a wide range of fundamental physics questions, and are thus a unique and powerful component of the HEP experimental portfolio.Comment: Submitted to the Proceedings of the US Community Study on the Future of Particle Physics (Snowmass 2021); Topical Group Report for CF06 (Cosmic Frontier Topical Group on Dark Energy and Cosmic Acceleration: Complementarity of Probes and New Facilitie

Cachimbos europeus de cerâmica branca, séculos XVI ao XIX: parâmetros básicos para análise arqueológica

O tabaco foi introduzido na Europa no final do século XV. Desde então, uma das formas mais comuns para o seu consumo foi o cachimbo, além do rapé, do tabaco de mascar, do charuto e, mais recentemente, dos cigarros. Os cachimbos de cerâmica branca, largamente produzidos e utilizados na Europa desde o século XV, são encontrados em sítios arqueológicos históricos ao redor do mundo, incluindo no Brasil, em decorrência do comércio internacional, que gradualmente se intensificou após o início da conquista europeia. Eles funcionam como excelentes elementos para datação de sítios e estratos arqueológicos, tendo sido estudados em vários países a partir dessa abordagem. Ainda, esse tipo de artefato, mais que fornecer datações, permite identificar redes comerciais entre nações e desenvolver discussões de cunho social e cultural. Contudo, eles foram pouco estudados no Brasil. Visando contribuir com os estudos nacionais dessa categoria material, este artigo oferece uma revisão da literatura internacional acerca do histórico da produção dos cachimbos europeus de caulim, incluindo apresentação dos principais centros produtores; da morfologia e decoração desses produtos, considerando a cronologia do fabrico; e dos métodos de análise dos diferentes cachimbos de caulim no âmbito da arqueologia histórica.Tobacco was introduced in Europe at the end of the 15th century. Since then, one of the most traditional means for its use has been the pipe, next to the powder version, chewing, cigars, and, more recently, cigarettes. White clay tobacco pipes, widely produced and used in Europe since the 15th century, are found in historical archaeological sites around the world, including Brazil, due to international trade, which gradually intensified with the European conquest of the New World. They are excellent guides for dating archaeological sites and layers. In addition, this type of artifact, more than a dating tool, permits identifying trading networks between nations and developing discussions of cultural and social nature. These pipes, however, have been understudied in Brazil. In order to contribute to studies of this type of artifact in our country, this paper offers a revision of the international literature on the history of clay pipe production in Europe, including the presentation of main production centers; morphology and decoration of these products, considering issues of fabrication chronology; and the methods used in Historical Archaeology for analyzing clay tobacco pipes
