ResumoTerrenos khondalíticos representam um significativo componente de áreas de fácies granulito/UHT e os gnaisses que ocorrem associados a esses complexos são, principalmente, tipos aluminosos. Estes terrenos representam uma história de acresção crustal, ocorrendo nas zonas de junções/suturas das massas continentais como, por exemplo, nas que propiciaram a formação do supercontinente Gondwana. Nos Terrenos Khondalíticos presentes no Estado do Rio de Janeiro e em suas regiões limítrofes, registram-se diversas ocorrências de Mn/grafita, Au e Zn/Ag, cujas expressões podem ter caráter tanto regional quanto local. No geral, as mineralizações citadas estão situadas em regiões formadas por intercalações de gnaisses aluminosos, com ou sem sillimanita, e de rochas ortogranulíticas. Nesses terrenos, afloram camadas de gnaisses grafitosos (teor de C~2%). Essas camadas podem estar acompanhadas de corpos de gonditos, alterados para óxidos-hidróxidos de manganês, como nas faixas khondalíticas Marangatu e Palma-Guaçuí, ou somente mineralizados em grafita, como na Faixa Khondalítica São Fidélis. Na Faixa Khondalítica Palma-Guaçuí, particularmente no segmento entre Palma (MG) e Laje do Muriaé (RJ), ocorre um pacote de gnaisse grafitoso sulfetado, interpretado como um antigo folhelho negro, com cerca de 20 km de extensão, contendo mineralizações auríferas. O ouro ocorre na forma livre e como inclusões (ouro invisível) em piritas dos tipos framboidal (singenética), flor de girassol (diagenética) e maciça (metamórfica). A sequência metassedimentar à qual se relaciona a mineralização de zinco de Rio Claro (possivelmente uma extensão da Faixa Khondalítica Marangatu) é bastante semelhante àquelas encontradas em depósitos canadenses sedimentares-exalativos de Zn-Pb-Ag, do tipo Shuswap e Monash. As rochas sílico-carbonáticas da Unidade Lídice, que encerram as zonas sulfetadas, foram geradas em ambiente plataformal raso, possivelmente com um componente evaporítico.Palavras Chave: Terrenos khondalíticos, manganês, grafita, ouro, zinco.AbstractKHONDALITIC TERRAINS: MAIN DOMAINS FOR MANGANESE, GRAPHITE, GOLD AND ZINC IN THE STATE OF RIO DE JANEIRO AND SURROUNDING REGIONS. Khondalite terrains represent a significant element in areas with granulite/UHT facies and the gneiss rocks that occur associated to these complexes are, especially, aluminous type. These terrains represent a history of crustal accretion, occurring in suture zones of continental masses as, for example, in those which contributed to the formation of the supercontinent Gondwana. In khondalite terrains in the State of Rio de Janeiro and in its neighboring regions, there are several occurrences of Mn/graphite, Au and Zn/Ag, whose expressions may have both regional and local character. In general, those mineralizations are located in regions consisting of intercalation of aluminous gneiss, with or without sillimanite, and of ortogranulite rocks. In those terrains, layers of graphitic gneiss (C content ~ 2%) arise. Such layers may be accompanied by gondite bodies, changed to oxide-hidroxide of manganese, as in Marangatu and Palm-Guaçuí Khondalitic Belts, or only mineralized in graphite, as in São Fidelis Khondalitic Belt. In Palma-Guaçuí Khondalite Belt, particularly in the segment between Palma (MG) and Laje do Muriaé (RJ), there is a set of sulphide graphite gneiss, considered as an ancient black shale, about 20 km long, containing auriferous mineralizations. Gold occurs in free form and as inclusions (invisible gold) in pyrites of framboidal type (syngenetic), sunflower type (diagenetic) and massive type (metamorphic). The metasedimentary sequence to which Rio Claro zinc mineralization relates (possibly an extension of Marangatu Khondalitic Belt) is quite similar to those found in sedimentary-exhalative Canadian deposits of Zn-Pb-Ag, Shuswap and Monash types. Silic-carbonate rocks of Lidice Unit, which delimit the sulfide zones, were generated in shallow platformal environment, possibly with a evaporitic component.Keywords: Khondalitic terrains, manganese, graphite, gold, zinc.

Abstract The result of field research conducted in a Rio de Janeiro favela, the article discusses transformations in the organization of community associations. In particular, it describes the weakening of local associations that are traditionally regarded as representative of the community and the rise of new forms of association, indicating their distinctive characteristics in terms of relations with external agents (from the state and other spheres) and forms of organization and action. We place these processes in a long timeframe, prior to the installation of the Police Pacification Units in 2009 and to the following entrance of new state and private agents. We review critical events in the history of the local political organization, to discuss the multiple assemblages that affect the organization of the favela residents.

AbstractLandslides are one of the most vital natural hazards on Earth. To satisfy the demand for protection against landslides, it is necessary to systematically assess and manage landslide hazards and risk. Landslide mechanisms related to hydrology are analyzed with focus in the major risks, and formal risk assessment methodologies are presented in the paper. Issues related to risk assessment are discussed and different steps are described. The management of accidents in slopes is discussed, with particular emphasis to Hong Kong and Rio de Janeiro in Brazil. Hong Kong is a region of China with a large population density and very mountainous. There is a history of tragic accidents in the slopes. The territory has a tradition of a high standard in the practice of slope engineering. The establishment of an efficient security system developed by Geotechnical Engineering Office was established in the territory. Also, specific aspects of slope instability in the state of Rio de Janeiro are discussed, and in Rio de Janeiro city, with focus on cases which occurred in the mountainous region of the State. The mega-disaster that occurred in 2011, with high number of deaths and significant economic losses, is studied with incidence in individual landslides.

El documento tiene como objetivo investigar uma versión de la historia de capoeira en la región sur del Río de Janeiro. Para ello, se realizó una encuesta que se estructura a partir de la metodología de la historia oral y las teorías acerca de la memoria. Las fuentes consultadas tienen como base los informes de ocho maestros de capoeira que trabajan en la región investigada. Los informes permiten observar la importancia de un maestro que es poco recordado por la memoria colectiva de los practicantes más nuevos. También es posible inferir que los maestros que optaron por una raíz que demarca identidad resisten las influencias culturales globalizadas, actualmente tienen menos cuotas de poder en el mercado de capoeira en la región.

Ras a1 Khaimah is the most northerly of the seven states comprising the United Arab Emirates and its Ruler, H. H. Sheikh Saqr bin Mohammad al-Qasimi, is keenly interested in the history of the state and its people. Survey carried out there jointly with Dr D. B. Doe in 1968 had focused attention on the site of JuIfar which lies just north of the present town of Ras a1 Khaimah (de Cardi, 1971, 230-2). Julfar was in existence in Abbasid times and its importance as an entrep6t during the sixteenth and seventeenth centuries-the Portuguese Period-is reflected by the quantity and variety of imported wares to be found among the ruins of the city. Most of the sites discovered during the survey dated from that period but a group of cairns near Ghalilah and some long gabled graves in the Shimal area to the north-east of the date-groves behind Ras a1 Khaimah (map, FIG. I) clearly represented a more distant past.

Portugal has port, Spain has sherry, Sicily has Marsala –– and California has angelica. Angelica is California's original wine: The intensely sweet, fortified dessert cordial has been made in the state for more than two centuries –– primarily made from Mission grapes, first brought to California by the Spanish friars. Angelica was once drunk in vast quantities, but now fewer than a dozen vintners make angelica today. These holdouts from an earlier age are each following a personal quest for the real. For unlike port and sherry, which have strict rules about their production, angelica never gelled into something so distinct that connoisseurs can say, ““This is angelica. This is not.”” This piece looks at the history of the drink, its foggy origins in the Mission period and on through angelica's heyday and down to its degeneration into a staple of the back-alley wino set. Several current vintners are profiled, and they suggest an uncertain future for this cordial.

The Moment

This publication is devoted to one of the episodes of I. A. Ilyin’s activity in the period “between two revolutions”. Before the October revolution, the young philosopher was inspired by the events of February 1917 and devoted a lot of time to speeches and publications on the possibility of building a new order in the state. The published archive text indicates that the development of Ilyin’s doctrine “on legal consciousness” falls precisely at this tragic moment in the history of Russia.

This paper examines the development of modern vaccination programme of Cooch Behar state, a district of West Bengal of India during the nineteenth century. The study has critically analysed the modern vaccination system, which was the only preventive method against various diseases like small pox, cholera but due to neglect, superstation and religious obstacles the people of Cooch Behar state were not interested about modern vaccination. It also examines the sex wise and castes wise vaccinators of the state during the study period. The study will help us to growing conciseness about modern vaccination among the peoples of Cooch Behar district.
