Dynamics of carbon, biomass, and structure in two Amazonian forests

Amazon forests are potentially globally significant sources or sinks for atmospheric carbon dioxide. In this study, we characterize the spatial trends in carbon storage and fluxes in both live and dead biomass (necromass) in two Amazonian forests, the Biological Dynamic of Forest Fragments Project (BDFFP), near Manaus, Amazonas, and the Tapajos National Forest (TNF) near Santarem, Para. We assessed coarse woody debris (CWD) stocks, tree growth, mortality, and recruitment in ground-based plots distributed across the terra firme forest at both sites. Carbon dynamics were similar within each site, but differed significantly between the sites. The BDFFP and the TNF held comparable live biomass (167 +/- 7.6 MgC.ha(-1) versus 149 +/- 6.0 MgC.ha(-1), respectively), but stocks of CWD were 2.5 times larger at TNF (16.2 +/- 1.5 MgC.ha(-1) at BDFFP, versus 40.1 +/- 3.9 MgC.ha(-1) at TNF). A model of current forest dynamics suggests that the BDFFP was close to carbon balance, and its size class structure approximated a steady state. The TNF, by contrast, showed rapid carbon accrual to live biomass (3.24 +/- 0.22 MgC.ha(-1).a(-1) in TNF, 2.59 +/- 0.16 MgC.ha(-1).a(-1) in BDFFP), which was more than offset by losses from large stocks of CWD, as well as ongoing shifts of biomass among size classes. This pattern in the TNF suggests recovery from a significant disturbance. The net loss of carbon from the TNF will likely last 10 - 15 years after the initial disturbance (controlled by the rate of decay of coarse woody debris), followed by uptake of carbon as the forest size class structure and composition continue to shift. The frequency and longevity of forests showing such disequilibruim dynamics within the larger matrix of the Amazon remains an essential question to understanding Amazonian carbon balance.

Projecto de Cooperacao Bilateral entre Cabo-Verde e os Países Baixos - Energias Renováveis - Relatório Final - 2ª Fase

o interesse da República de Cabo Verde na utiliza9ao da energia renovável é basicamente económico. O país é muito pobre e todo o custo de energia pesa profundamente na sua economia nacional,visto nao existirem recursos de energia "tradicional". A utiliza~ao da energia renovável para bombagem de água é por isso, de grande importancia porque reduz a importa~ao de petróleo. Tanto a energia eólica como a energia solar oferecem grandes possibilidades em Cabo Verde. O país está sendo atingido pelo pior e mais langa período de seca jamais experimentado na sua história. Pode-se imaginar os problemas enfrentados para abastecimento de água a populac~o, abeberamento de animais e irriga- .., , ,,, , ~ao das poucas areas agrlcolas. O abastecimento de água potável é extremamente importante neste país, é apenas para a sobrevivencia da maior parte da sua popula9ao rural (190.000 habitantes), com pouco poder aquisitivo dado a diminuisao da área agrícola irrigada e a quantidade de gado, nos últimos 15 anos. Na agricultura irrigada, de momento totalizando apenas 2.000 ha, utilizase relativamente grande quantidade de combustível, porque 50% consiste em irrigasao por bombagem. Por esta razao o governo de Cabo Verde estimula fortemente a utilizasao das energias renováveis. As actividades neste campo come~aram em 1977 com a cria~ao da Divisao de Energias Renováveis (DER) dentro do Ministério do Desenvolvimento Rural (MUR). O governo de Cabo Verde e a PNUD (Projecto PNUD CVI/76/X05 - Demonstrasao de Energia Nao Convenciorial) puseram fundos a disposi~ao. Este projecto contribuiu com 3 aerogeradores e um volontário, Sr. Van Meel, que trabalhou anteriormente no Grupo de Energia Eólica de Eindhoven e que faz parte do CWD. Desde o seu início, a Divisao deu prioridade a bombagem de água para o abastecimento de água potável, o que foi e continua a ser urna necessidade urgente nas Ilhas de Cabo Verde. Os Servi~os da Igreja Mundial ofereceram 25 aerobombas Dempster com ventoinha de 8' de diametro e mais tarde a UNICEF distribuiu 10 Dempsters de ]4'. Gradualmente mais organiza90es financiadoras envolveram-se nas actividades da DER, como por exemplo a ClMADE, FAC, Embaixada An~ricana, Embaixada do Canadá, ICCO, etc. O Ministério do Desenvolvimento e Coopera9ao dos Países Baixos (DGIS) encarregou- se, em 1979, da norneasao do voluntárío da PNUD. Também em 1979 a USAID envolveu-se. Foi reconhecido e implementado um projecto de energia renovável (ref. 1). Este projecto comecou em Agosto de 1980. O papel prin cipal do projecto consistia na aquisiq~o de material e equipamento para urna nova oficina da DER. Urna das premissas do projecto era que o DGIS prestaria assistencia él Divisao. A pedido do DGIS a CWD realizou um estudo sobre a viabilidade de aplica9ao de aerobombas durante o primeiro semestre de 1980 (ref. 2). O estudo revelou que 75% das necessidades de água por bombagem em Cabo Verde, pode ria ser desempenhado pelos moinhos. - O projecto proposto diz respeito nao apenas a assistencia técnica, mas também ao financiamento da nova oficina e a aquisi9ao de cerca de 30 moi nhos. Este projecto bilateral entre Cabo Verde e os Países Baixos - Energias Renováveis", depois da aprova<;ao de Cabo Verde e do DGIS, veia a comecar no dia 1 de Julho de 1981 e estendeu-se por 3 anos. O período de 1977 a Julho de 1981 classifica-se agora como a primeira fase das actividades. Durante este período o CWD contribuiu com a assist€ncia técnica. O período de Julho de 1981 a Julho de 1984 é classificado como segunda fase e será relatado neste documento. O projecto foi executado pela DER. O Director da DER é, desde Fevereiro de 1983, o Sr. Daniel Livramento, licenciado em Física (Brasil 1982). Outros funcionários do corpo directivo sao o Sr. David Cardoso (desde Novem bro de 1983) e muito recentemente, desde Maio de 1984, o Sr. F. Ferreira7 A colaboracao dos Países Baixos para o projecto tem sido efectuada por En genheiros Consultores do DHV, em nome e como associados do CWD. O Sr. K.Versteegh, consultor do CWD, comecou a trabalhar para o projecto em 1 de Julho de 1981 e o Sr. N.Pieterse,~consultordo CWD, em 15 de Setembro de 1981. O Sr. Van Meel deixou o projecto a 1 de Novembro de 1981. O projecto foi avaliado em Novembro de 1983, por urna missao tripartida (Cabo Verde, USAID, DGIS) - Ref. 3. As conclusoes desta missao de avaliacao foram, em geral, positivas e o prolongamento do projecto foi fortemen te recomendado, com €nfase sobre aprodu~ao local. Entretanto, a DER e o CWD prepararam urna proposta para a extensao do projecto por mais 3 anos (Ref. 4). Esta extensao foi aprovada por Cabo Verde e pelo DGIS. O Sr. Versteegh foi substituído em Julho de 1984 e o Sr. Pieterse será substituido em Setembro de 1984 pelos Srs. J.Diepens e H. van der Spek, respectivamente. O conteúdo deste relatório é o seguinte: No capitulo 2 é apresentada urna exposi~ao do trabalho que incluiu um resumo das actividades realizadas na fase 1.

Disputa territorial por las Islas Dokdo en las relaciones políticas entre Corea del Sur y Japón (2005-2012)

Las relaciones políticas y económicas entre Corea del Sur y Japón pasaban por su mejor momento en los primeros años del siglo XXI, cuando la disputa territorial por las islas Dokdo, un grupo de islotes ubicados en el mar de Japón y que por décadas han simbolizado el fin de la ocupación del país nipón en territorio coreano, causara nuevas y significativas tensionen entre los dos países. Dicho fenómeno, se sugiere fundamental en la comprensión de las nuevas relaciones bilaterales entre los dos actores y se presenta como foco de análisis en la presente monografía. El documento, presenta un análisis descriptivo de la disputa territorial por las Islas y de sus efectos en las relaciones entre los dos países, tanto en los ámbitos político, social y económico.

Fate of prions in soil: Detergent extraction of PrP from soils

The transmissible spongiform encephalopathies (TSEs) are caused by infectious agents whose structures have not been fully characterized but include abnormal forms of the host protein PrP, designated PrPSc, which are deposited in infected tissues. The transmission routes of scrapie and chronic wasting disease (CWD) seem to include environmental spread in their epidemiology, yet the fate of TSE agents in the environment is poorly understood. There are concerns that, for example, buried carcasses may remain a potential reservoir of infectivity for many years. Experimental determination of the environmental fate requires methods for assessing binding/elution of TSE infectivity, or its surrogate marker PrPSc, to and from materials with which it might interact. We report a method using Sarkosyl for the extraction of murine PrPSc, and its application to soils containing recombinant ovine PrP (recPrP). Elution properties suggest that PrP binds strongly to one or more soil components. Elution from a clay soil also required proteinase K digestion, suggesting that in the clay soil binding occurs via the N-terminal of PrP to a component that is absent from the sandy soils tested.

Precipitation variability in Sao Paulo State, Brazil

The State of Sao Paulo is the richest in Brazil, responsible for over 30% of the Brazilian gross rate. It has a population of around 30 million and its economy is based on agriculture and industrial products. Any change in climate can have a profound influence on the socio-economics of the State. In order to determine changes in total and extreme rainfall over Sao Paulo State, climate change indices derived from daily precipitation data were calculated using specially designed software. Maps of trends for a subset of 59 rain gauge stations were analysed for the period 1950-1999 and also for a subset of this period, 1990-1999, representing more recent climate. A non-parametric Mann-Kendall test was applied to the time series. Maps of trends for six annual precipitation indices (annual total precipitation (PRCPTOT), very heavy precipitation days (R20mm), events greater than the 95th percentile (R95p), maximum five days precipitation total (RX5day), the length of the largest wet spell (CWD) and the length of the largest dry spell (CDD)) were analysed for the entire period. These exhibited statistically significant trends associated with a wetter climate. A significant increase in PRCPTOT, associated with very heavy precipitation days, were observed at more than 45% of the rain gauge stations. The Mann-Kendall test identified that the positive trend in PRCPTOT is possibly related to the increase in the R95p and R20mm indices. Therefore, the results suggest that there has been a change in precipitation intensity. In contrast, the indices for the more recent shorter time series are significantly different to the longer term indices. The results indicate that intense precipitation is becoming concentrated in a few days and spread over the period when the CDD and R20mm indices show positive trends, while negative ones are seen in the RX5day index. The trends found could be related to many anthropogenic aspects such as biomass burning aerosols and land use.

Inclusão da criança com deficiência na estratégia de saúde da família

The objective of analyze the shift of the working process of the ESF team in care of children with disabilities, from awareness-raising actions. It is a qualitative study, with the action-research method. Thirteen health professionals were involved from two teams of ESF unit area of the Unidade de Saúde da Família Dr. Chico Porto (UBSFCP) in Mossoró, from March to August 2011. Data were analyzed following the direction of freirean s thematic analysis. In the situational diagnosis of the current reality of CwD assistance in that UBSFCP, through participant observation and application of semi-structured interviews with professionals, we realize that despite these actions carry some assistance to the CwD, in practice few are used for inclusion and accessibility. The monitoring of the CwD is done through individual consultations by each team professional, home visits when possible, both ruled on the complaints and problems, with little solving in the used actions. Since the need for a change in the treatment model and training requirements as pointed out by professionals in the interview, then we decided to build the proposed of training suggested by the multidisciplinary team and put together collectively the achievement of this moment in all its phases. In the step of implementation (action), aspects related to the current situation in Brazil and Mossoró (Laws, policies and health care) for the CwD and CwD Assistance and their family in the ESF in the first two moments of the first training (action) were contemplate. On the second day we discussed the specialized care to CwD, contribution of the Handicapped Parents and Friends Association of Mossoró and in a second moment a workshop was held in which awareness for inclusion of CwD and actions of ESF were discussed. All these moments were discussed and collectively constructed. In the evaluation, we found that implementation (action) allowed to the professional the comprehension of new understandings about people with disabilities, on ways to include, guiding, caring, watching, and mainly to have a new vision on health assistance of the CwD, expanding assistance beyond clinical aspects and recognizing the educational aspects of the rights and duties of citizens and the inclusion of these children in the social spaces area. As difficulties, we face the need for some professionals to be absent to attend another job, solve personal problems, and little or no participation. Thus, during this action-research, the subjects were able to realize the importance of carrying out their practice to the quality of life for him and to the one they care
