An ethnobotanical survey of medicinal plants in the Eastern Himalayan zone of Arunachal Pradesh, India

Aim of the study: The medicinal plants are integral source of easily available remedy used in rural healthcare system. This study was conducted among three major ethnic groups namely the Nocte, the Nyishi and the Adi in the Eastern Himalayan region of Arunachal Pradesh to evaluate their comparative knowledge on medicinal plants. Materials and methods: The three remote districts of Arunachal Pradesh namely the Tirap, the Dibang Valley and the Papum Pare were surveyed through interviewing of randomly selected 237 participants using semi-structured questionnaire and regular field visits to selected districts. Results: We recorded the traditional use of 74 medicinal plants species belonging to 41 taxonomic plant families used for treating a total of 25 different diseases/ailments. The informant consensus factor (ICF) values demonstrated that local people tend to agree more with each other in terms of the plants used to treat malaria (0.71), jaundice (0.62), urological problems (0.56), dermatological disorders (0.45), pain (0.30), and respiratory disorder (0.33), and while the general health (0.15) and gastro-intestinal disorders category (0.28) were found low ICF values. Conclusion: Of the total 74 species recorded, the highest number of medicinal plants (36 species) was reported from the Adi of Lower Dibang Valley followed by the Nocte of the Tirap (25 species) and the Nyishi ethnic groups of Papum Pare districts (13 species). In the present study, we found that the men, elder people and illiterate ones had better knowledge on medicinal plants as compared to women, younger and literate people. Findings of this documentation study can be used as an ethnopharmacological basis for selecting plants for future phytochemical and pharmaceutical studies. (C) 2010 Elsevier Ireland Ltd.

Arquitetura crustal da bacia de Almada no contexto das bacias da margem lesste da América do Sul

A Bacia de Almada, localizada no estado da Bahia, compartilha características similares com as outras bacias da margem leste do Brasil, quando é analisada segundo aspectos como os processos sedimentares e o regime de esforço dominante durante a sua formação. Observa-se uma diferença marcante em relação as outras bacias quando é analisada sob a ótica da composição da crosta transicional, uma vez que não se registra atividade vulcânica durante a fase rifte. A aquisição de um extenso levantamento sísmico 3D, com cabos de 6 km de comprimento e 9.2 segundos de tempo de registro (tempo sísmico duplo), resultaram em imagens sísmicas de boa qualidade das estruturas profundas do rifte. Adicionalmente, estudos de modelagem gravimétrica foram integrados com a análise sísmica para corroborar o modelo geológico. A Bacia de Almada é parte dos sistemas de rifte continentais, desenvolvidos durante o Berriasiano até o Aptiano, que antecederam a quebra do continente do Gondwana, evoluindo posteriormente para uma margem passiva divergente. O processo do rifteamento desenvolveu cinco sub-bacias de orientação NNE-SSO, desde posições terrestres até marinhas profundas, produzindo um arcabouço estrutural complexo. Os perfis da sísmica profunda mostram o afinamento progressivo da crosta continental até espessuras da ordem de 5 km, abaixo da sub-bacia mais oriental, com fatores de estiramento crustal próximo a 7 antes do desenvolvimento de crosta oceânica propriamente dita. As imagens sísmicas de boa qualidade permitem também o reconhecimento de sistemas de falhas lístricas que se iniciam na crosta superior, evoluem atravessando a crosta e conectando as sub-bacias para finalizar em um descolamento horizontal na crosta inferior estratificada. Adicionalmente, a bacia apresenta um perfil assimétrico, compatível com mecanismos de cisalhamento simples. As margens vulcânicas (VM) e não vulcânicas (NVM), são os extremos da análise composicional das margens divergentes continentais. Na Bacia de Almada não se reconhecem os elementos arquiteturais típicos das VM, tais como são as grandes províncias ígneas, caracterizadas por cunhas de refletores que mergulham em direção ao mar e por intenso vulcanismo pré- e sin-rifte nas bacias. Embora a margem divergente do Atlântico Sul seja interpretada tradicionalmente como vulcânica, o segmento do rifte ao sul do Estado da Bahia apresenta características não-vulcânicas, devido à ausência destes elementos arquiteturais e aos resultados obtidos nas perfurações geológicas que eventualmente alcançam a seqüência rifte e embasamento. Regionalmente a margem divergente sul-americana é majoritariamente vulcânica, embora a abundância e a influência do magmatísmo contemporâneo ao rifte seja muito variável. Ao longo da margem continental, desde a Bacia Austral no sul da Argentina, até a Bacia de Pernambuco no nordeste do Brasil, podem ser reconhecidos segmentos de caráter vulcânico forte, médio e não vulcânico. Nos exemplos clássicos de margens não vulcânicas, como a margem da Ibéria, a crosta transicional é altamente afinada podendo apresentar evidências de exumação de manto. Na Bacia de Almada, a crosta transicional apresenta importante estiramento embora não haja evidências concretas de exumação de manto. Os mecanismos responsáveis pela geração e intrusão dos grandes volumes de magma registrados nas margens divergentes são ainda sujeitos a intenso debate. Ao longo da margem divergente sul-americana há evidências da presença dos mecanismos genéticos de estiramento litosférico e impacto de plumas. Alternativamente estes dois mecanismos parecem ter tido um papel importante na evolução tectônica da margem sudeste e sul, diferenciando-as da margem continental onde foi implantada a Bacia de Almada.

I. Foehn winds of southern California.
An investigation of the hot, dry and dust laden winds occurring in the late fall and early winter in the Los Angeles Basin and attributed in the past to the influences of the desert regions to the north revealed that these currents were of a foehn nature. Their properties were found to be entirely due to dynamical heating produced in the descent from the high level areas in the interior to the lower Los Angeles Basin. Any dust associated with the phenomenon was found to be acquired from the Los Angeles area rather than transported from the desert. It was found that the frequency of occurrence of a mild type foehn of this nature during this season was sufficient to warrant its classification as a winter monsoon. This results from the topography of the Los Angeles region which allows an easy entrance to the air from the interior by virtue of the low level mountain passes north of the area. This monsoon provides the mild winter climate of southern California since temperatures associated with the foehn currents are far higher than those experienced when maritime air from the adjacent Pacific Ocean occupies the region.

II. Foehn wind cyclo-genesis.
Intense anticyclones frequently build up over the high level regions of the Great Basin and Columbia Plateau which lie between the Sierra Nevada and Cascade Mountains to the west and the Rocky Mountains to the east. The outflow from these anticyclones produce extensive foehns east of the Rockies in the comparatively low level areas of the middle west and the Canadian provinces of Alberta and Saskatchewan. Normally at this season of the year very cold polar continental air masses are present over this territory and with the occurrence of these foehns marked discontinuity surfaces arise between the warm foehn current, which is obliged to slide over a colder mass, and the Pc air to the east. Cyclones are easily produced from this phenomenon and take the form of unstable waves which propagate along the discontinuity surface between the two dissimilar masses. A continual series of such cyclones was found to occur as long as the Great Basin anticyclone is maintained with undiminished intensity.

III. Weather conditions associated with the Akron disaster.
This situation illustrates the speedy development and propagation of young disturbances in the eastern United States during the spring of the year under the influence of the conditionally unstable tropical maritime air masses which characterise the region. It also furnishes an excellent example of the superiority of air mass and frontal methods of weather prediction for aircraft operation over the older methods based upon pressure distribution.

IV. The Los Angeles storm of December 30, 1933 to January 1, 1934.
This discussion points out some of the fundamental interactions occurring between air masses of the North Pacific Ocean in connection with Pacific Coast storms and the value of topographic and aerological considerations in predicting them. Estimates of rainfall intensity and duration from analyses of this type may be made and would prove very valuable in the Los Angeles area in connection with flood control problems.

Rangia and Marsh Clams, Rangia cuneata, R. flexuosa, and Polymesoda caroliniana, in Eastern México: Distribution, Biology and Ecology, and Historical Fisheries

Rangia and marsh clams, Rangia cuneata, R. flexuosa, and Polymesoda caroliniana, occur in brackish waters along México’s eastern coast from the northern State of Tamaulipas to the southern State of Campeche. The clams were important to the prehispanic people in the southern part of the State of Veracruz, where they were used as food and as construction material. In modern times, they are harvested for food. The fishermen wade in shallow water and harvest the clams in soft sediments by hand. Annual landings of whole clams during a recent 5-yr period, 1998–2002, were 1,139–1,695 t. The only area with a substantial ongoing clam fishery is in the Lower Papaloapan River Basin, including Alvarado Lagoon, where as many as 450 fishermen are licensed harvesters. This fishery for the Rangia and marsh clams is the most important clam fishery along México’s Gulf Coast.

下扬子北缘前陆盆地形成演化与油气赋存条件

The foreland basin on the northern margin of the lower reach of the Yangtze river (the lower Yangtze foreland basin) is tectonically situated in the basin-mountain transitional area along the southeastern flank of the Dabie mountains. The early formation and development of the basin is closely related to the open-up of the Mian-Lue paleo-oceanic basin on the southern margin of the Central Orogenic System represented by Qinling-Dabei orogenic belt, while the tectonic evolution of the middle-late stage of the basin is mainly related to development of the Mian-Lue tectonic zone that occurred on the basis of the previous Mian-Lue paleo-suture. The foreland basin of the northern rim of the lower reach of the Yangtze river was formed during the middle-Triassic collision between the Yangtze and North China plates and experienced an evolution of occuirence-development-extinction characterized by marine facies to continental facies and continental margin to intracontinent in terms of tectonic setting.The foreland basin (T2-J2) was developed on the basis of the passive continental marginal basin on the south side of the Mian-Lue paleo-ocean and superimposed by late Jurassic-Tertiary fault basin. The tectonic setting underwent a multiple transformation of rifting-collisional clososing-tensional faulting and depression, which resulted in changes of the property for the basin and the final formation of the superposed compose basin in a fashion of 3-story-building. According to the tectonic position and evolution stages of plate collision happening on the southeastern margin of the Dabie mountains, and tectono-tratigraphic features shown by the foreland basin in its main formational period, the evolution of the foreland basin can be divided into four stages: 1) pre-orogenic passive margin (P2-Ti). As the Mian-Lue ocean commenced subduction in the late-Permian, the approaching of the Yangtze and North China plates to each other led to long-periodical and large-scale marine regression in early Triassic which was 22 Ma earlier than the global one and generated I-type mixed strata of the clastic rocks and carbonate, and I-type carbonate platform. These represent the passive stratigraphy formed before formation of the foreland basin. 2) Foreland basin on continental margin during main orogenic episode (T2.3). The stage includes the sub-stage of marine foreland basin (T2X remain basin), which formed I-type stratigrphy of carbonate tidal flat-lagoon, the sub-stage of marine-continental transition-molasse showing II-type stratigraphy of marine-continental facies lake - continental facies lake. 3) Intracontinental foreland basin during intracontinental orogeny (Ji-2)- It is characterized by continental facies coal-bearing molasses. 4) Tensional fault and depression during post-orogeny (J3-E). It formed tectono-stratigraphy post formation of the foreland basin, marking the end of the foreland evolution. Fold-thrust deformation of the lower Yangtze foreland basin mainly happened in late middle-Jurassic, forming ramp structures along the Yangtze river that display thrusting, with deformation strength weakening toward the river from both the Dabie mountains and the Jiangnan rise. This exhibits as three zones in a pattern of thick-skinned structure involved the basement of the orogenic belt to decollement thin-skinned structure of fold-thrust from north to south: thrust zone of foreland basin on northern rim of the lower reach of the Yangtze river, foreland basin zone and Jiannan compose uplift zone. Due to the superposed tensional deformation on the earlier compressional deformation, the structural geometric stratification has occurred vertically: the upper part exhibits late tensional deformation, the middle portion is characterized by ramp fault -fold deformation on the base of the Silurian decollement and weak deformation in the lower portion consisting of Silurian and Neo-Proterozoic separated by the two decollements. These portions constitutes a three-layered structural assemblage in a 3-D geometric model.From the succession of the lower reach of the Yangtze river and combined with characteristics of hydrocarbon-bearing rocks and oil-gas system, it can be seen that the succession of the continental facies foreland basin overlies the marine facies stratigraphy on the passive continental margin, which formed upper continental facies and lower marine facies hydrocarbon-bearing rock system and oil-gas forming system possessing the basic conditions for oil-gas occurrence. Among the conditions, the key for oil-gas accumulation is development and preservation of the marine hydrocarbon-bearing rocks underlying the foreland basin. The synthetic study that in the lower Yangtze foreland basin (including the Wangjiang-Qianshan basin), the generation-reservoir-cover association with the Permian marine facies hydrocarbon-bearing rocks as the critical portion can be a prospective oil-gas accumulation.Therefore, it should aim at the upper Paleozoic marine hydrocarbon-bearing rock system and oil-gas forming system in oil-gas evaluation and exploration. Also, fining excellent reservoir phase and well-preserved oil-gas accumulation units is extremely important for a breakthrough in oil-gas exploration.

Synthesis of the Piacenzian onshore record between the Aveiro and Setubal parallels (Western portuguese margin)

Onshore, the Piacenzianof the Mondego and Lower Tagus Tertiary basins comprises siliciclastic sediments deposited in shallow marine to continental environments. The outcrops of the deposits are relatively widespread in the Aveiro and Seuibal region. A lithostratigraphic synthesis based on the correlation of geological sections, is presented for the two basins. In general, the Piacenzian sediments display a regressive sucession. The Late Tortonian-Zanclean (?) confined drainage pattern changed at the beginning of Piazencian, to fluvial systems draining to the Atlantic, and capturing the drainage of the inner parts of the Hesperic Meseta. The Piacenzian sedimentary sequence post-dates one of the uprising phases during Neogene compression, recorded by a strong regional unconformity. Some local active faulting - as in Lousa, Rio Maior and Senibal- Pinhal Novo - allowed the local thickening of the sedimentary record. Later compressive tectonism continues to generate reverse faulting and diapiric reactivation, affecting those sediments. Currently, the Piacenzian deposits culminates the marginal piedmonts, widely eroded by the Quaternary fluvial dissection.

Estudo do impacte da institucionalização em lares na satisfação das necessidades humanas fundamentais : perspectiva dos idosos residentes

RESUMO O envelhecimento populacional, nos países ditos “desenvolvidos”, tem sido largamente discutido a nível internacional pelas suas implicações económicas, sociais e de saúde. Uma das prioridades de intervenção face a este fenómeno é promover o aumento de pessoas idosas autónomas inseridas no seu contexto social e familiar habitual. No entanto, nem sempre esse objectivo é atingido e a muitas pessoas idosas restam os lares, ou preferem-nos, como opção de alojamento e de satisfação das necessidades humanas fundamentais. O principal objectivo deste estudo foi procurar saber se a institucionalização no lar teve impacte na satisfação habitual das necessidades humanas fundamentais das pessoas idosas. Como objectivos secundários pretendeu-se complementar esta informação com alguns aspectos relacionados com o processo de institucionalização e perceber se existem diferenças significativas no que respeita ao sexo, grupo etário ou tempo de internamento. Foram incluídas no estudo 125 pessoas com 65 ou mais anos, residentes em 15 lares com alvará de iniciativa privada, pertencentes à Região de Lisboa e Vale do Tejo, no distrito de Setúbal. Os dados foram obtidos através de um questionário construído para o efeito pela autora. As principais conclusões do estudo apontaram para um impacte negativo da institucionalização na satisfação habitual de algumas necessidades que se enquadram no plano social, nomeadamente ocupar-se para se sentir útil, recrear-se e comunicar com os semelhantes. Nas diferentes necessidades, de uma forma geral, a institucionalização teve um impacte negativo no que respeita às dimensões relacionadas com privacidade e preferência individual. Por outro lado, a institucionalização parece ter tido um impacte positivo nas dimensões relacionadas com a segurança e a acessibilidade. Não foram encontradas diferenças significativas no que respeita ao número médio de respostas favoráveis ao lar ou à casa entre os grupos etários ou quanto ao tempo de internamento. Apesar disso, encontraram-se diferenças no que respeita ao grau de satisfação em residir num lar, sendo que o nível de satisfação com a institucionalização foi maior nas pessoas que residiam no lar há mais de um ano, comparativamente às que residiam no lar há um ano ou menos.-------------------------------------------- ABSTRACT: The ageing of the population of the more developed countries has been largely discussed internationally because of its economic, social and health implications. One of the priorities of intervention facing the ageing phenomenon is to promote the increase of autonomous elderly, within their usual social and familiar environment. Not always this goal is achieved and many elderly have nursing homes as option, or voluntary choose them, for lodgement and fundamental human needs satisfaction. The main goal of this study was to search whether the nursing home institutionalization had impact in the satisfaction of fundamental human needs. As secondary goals it was established to complement this information with some aspects of the institutionalization process, as well as to analyse if there were significant differences as far as sex, age groups or institutionalization time. The study sample included 125 individuals aged 65 years or more, living in 15 private nursing homes with approved legal certification, belonging to the Lisboa and Tagus Valley Region, in the district of Setúbal. Data were collected through a questionnaire designed for this study by the author. The main conclusions of this study pointed at a negative impact of institutionalization on the usual satisfaction of some human needs included at the social field, namely occupation, recreation and communication. At another level of needs, in a general way, institutionalization had negative impact concerning privacy and individual preferences dimensions. On the other hand, institutionalization appeared to have a positive impact in safety and accessibility dimensions. It was not found significant differences between age groups or institutionalization time as far as the average positive answers in favour to nursing home or house. Notwithstanding, there were differences relating to satisfaction in living at the nursing home being the satisfaction higher in residents who lived at the nursing home for more than a year, comparatively to those that lived at the nursing home for a year or less.

Prevenção terciária em saúde mental : novas respostas em Portugal

RESUMO - Apresenta-se a caracterização e a descrição das novas respostas, bem como dos dispositivos que as permitiram organizar, quanto à prevenção terciária em saúde mental em Portugal. Detalha-se a Região de Lisboa e Vale do Tejo por ser a que mais estruturas criou e que foi alvo do estudo das autoras. Até ao final de 2001 beneficiavam 754 pessoas desta oferta de serviços no nosso país, das quais 473 na Região de Lisboa e Vale do Tejo. A maior parte destes beneficiários, 299, participa em actividades de fórum sócio-ocupacional, estando 99 pessoas inseridas em estruturas residenciais. Daí que se entenda que houve uma melhoria quanto à cobertura de necessidades em termos de prevenção terciária/ reabilitação no nosso país. Considera-se, contudo, que ainda muito está por fazer, uma vez que se continua muito aquém dos ratios de oferta de serviços internacionalmente recomendados. Considera-se desejável que se alargue e aprofunde este projecto, enquadrado com mais rigor em termos de diagnóstico de necessidades nacionais e com uma coordenação mais centralizada que potencie uma melhor gestão do seu quadro de exigências.

Reconstruction et étude de la variabilité du régime alimentaire des sociétés préhispaniques de la basse vallée de Santa, Pérou

Ce projet de recherche porte principalement sur la reconstruction du régime alimentaire à l’aide d’une approche paléochimique. Des analyses isotopiques du carbone de l’azote ont été réalisées sur le collagène des os sur un échantillon de trente-huit individus provenant de trois sites différents de la basse vallée de Santa, sur la côte nord du Pérou : El Castillo, Guadalupito et Huaca China. Parmi les individus sélectionnés, certains sont affiliés aux groupes des Gallinazo, des Mochica, des Tanguche ou des Chimú couvrant ainsi la Période intermédiaire ancienne, l’Horizon moyen et la Période intermédiaire récente. L’approche isotopique a été utilisée afin de caractériser dans un premier temps, le régime alimentaire de la population globale en la comparant à d’autres groupes préhispaniques de l’Aire andine. Les résultats obtenus sur trente-deux individus suggèrent une alimentation variée incluant le maïs ainsi que des ressources marines, illustrant que ces groupes agriculteurs exploitaient les deux types d’écosystèmes à leur portée. Ces résultats sont supportés par l’analyse du carbone sur l’apatite pour cinq individus. Le second but fut d’étudier la variabilité du régime alimentaire entre les différents individus de l’échantillon, en fonction de la période d’occupation, du site de provenance, de l’affiliation culturelle, de l’âge et du sexe et du statut social. La petite taille de l’échantillon a limité considérablement la discussion de ces différents paramètres. Il a toutefois été possible de remarquer un accès aux ressources riches en protéines plus avantageux pour les hommes et la présence de possibles différences dans l’alimentation chez les individus juvéniles. Finalement, la confrontation des données funéraires à la reconstruction du régime alimentaire a été faite pour cinq cas particuliers de pratiques funéraires provenant du site El Castillo, premier centre régional de la civilisation Mochica dans la basse vallée de Santa. Dans tous les cas, le régime alimentaire suggéré par les compositions isotopiques supporte les interprétations des statuts sociaux de ces individus faites à partir des contextes funéraires.

Deteção e Quantificação Precoce de Clostridium perfringens em Frangos de Crescimento Rápido e de Plumagem Branca na Região de Lisboa e Vale do Tejo

Clostridium perfringens é uma bactéria anaeróbia Gram positiva, formadora de esporos e produtora de toxinas capazes de causar um amplo espectro de doenças em humanos e animais. Em frangos de crescimento rápido e de plumagem branca pode causar lesões e manifestações clínicas severas como enterite necrótica aviária (ENA), associada a uma baixa eficiência produtiva e avultadas perdas económicas. Neste estudo pretendeu-se avaliar a utilização de um teste de ensaio imunocromatográfico de fluxo lateral, o Clostridium FirstTestTM, para deteção e quantificação precoce de C. perfringens em frangos de crescimento rápido e plumagem branca e posterior relação entre a presença do agente e as características dos bandos (peso médio à chegada, idade dos bandos à amostragem), fatores ambientais (densidade populacional, temperatura ambiente, humidade da cama) e os indicadores de produção (ganho médio diário, Índice de Conversão Alimentar e percentagem de mortalidade). Para tal, foram analisadas amostras fecais de trinta bandos, em dezoito explorações integradas, na Região de Lisboa e Vale do Tejo. De acordo com a classificação do Clostridium FirstTestTM, dos trinta bandos amostrados entre o décimo primeiro e o décimo quinto dia de vida, 30 % foram classificados como “Positivo” (n=9) e 10 % foram classificados como “Muito Positivo” (n=3); apresentando concentrações médias de C. perfringens de 0,1322 ng/ml e 0,3267 ng/ml, respectivamente. Os restantes bandos, 60% (n=18), foram considerados “Normal” e apresentaram concentrações médias de C. perfringens de 0,0283 ng/ml. As amostras fecais dos bandos classificados de “Positivo” e “Muito Positivo” foram posteriormente sujeitas a análise microbiológica apresentando ambos os grupos unidades formadoras de colónias (UFC), identificadas como C. perfringens. Verificou-se que não existe relação entre os resultados do Clostridium FirstTestTM e as características dos bandos, os fatores ambientais e os indicadores de produção. Verificou-se uma diminuição dos níveis de C. perfringens nos bandos sujeitos a tratamento.

Biała Góra: the forgotten colony in the Medieval Pomeranian-Prussian borderlands

Biała Góra 3 is a small settlement founded in the late twelfth or early thirteenth century AD in the disputed Christian borderlands of Northern Europe. The incorporation of Pomerania into the Polish state in the tenth century was followed by a process of colonisation across the lower Vistula valley, which then stalled before resuming in the thirteenth century under the Teutonic Order. Biała Góra 3 is unusual in falling between the two expansionist phases and provides detailed insight into the ethnicity and economy of this borderland community. Pottery and metalwork show strong links with both Pomeranian and German colonists, and caches of bricks and roof tiles indicate durable buildings of the kind associated with the monastic and military orders. Evidence for the presence of merchants suggests Biała Góra 3 was one of many outposts in the commercial network that shadowed the Crusades.
