Ecologia e manejo de patauå (Oenocarpus bataua Mart.) para produção de frutos e óleo.
O patauĂĄ (Qenocarpus bataua) Ă© uma palmeira com ocorrĂȘncia em toda RegiĂŁo AmazĂŽnica, da qual se utilizam as folhas, frutos, estipe e raĂzes. Dos frutos pode ser extraĂdo um Ăłleo semelhante ao azeite de oliva, muito apreciado para uso na culinĂĄria. No Brasil, o Ăłleo de patauĂĄ jĂĄ foi muito consumido, tendo sido inclusive exportado para outros paĂses. No entanto, sua exploração nĂŁo foi feita de forma sustentĂĄvel, levando ao extermĂnio grandes populaçÔes naturais, principalmente na AmazĂŽnia Oriental. Hoje, a exploração do patauĂĄ para produção de suco e Ăłleo Ă© praticamente inexistente, ocorrendo apenas para uso domĂ©stico apesar de seu excelente potencial como produtor de Ăłleo. Este trabalho tem a finalidade de fornecer informaçÔes gerais sobre a espĂ©cie e tambĂ©m um pequeno estudo da produtividade de Ăłleo de patauĂĄ em um local de ocorrĂȘncia no Vale do Rio Acre. Espera-se que a comercialização de frutos do patauĂĄ e tambĂ©m a produção de Ăłleo venham a ser uma realidade no Estado, contribuindo para diversificar a produção extrativista.bitstream/item/117339/1/12179.pd
Consistency of Financial Interest Disclosures in the Biomedical Literature: The Case of Coronary Stents
Background
Disclosure of authors' financial interests has been proposed as a strategy for protecting the integrity of the biomedical literature. We examined whether authors' financial interests were disclosed consistently in articles on coronary stents published in 2006.
Methodology/Principal Findings
We searched PubMed for English-language articles published in 2006 that provided evidence or guidance regarding the use of coronary artery stents. We recorded article characteristics, including information about authors' financial disclosures. The main outcome measures were the prevalence, nature, and consistency of financial disclosures. There were 746 articles, 2985 authors, and 135 journals in the database. Eighty-three percent of the articles did not contain disclosure statements for any author (including declarations of no interests). Only 6% of authors had an article with a disclosure statement. In comparisons between articles by the same author, the types of disagreement were as follows: no disclosure statements vs declarations of no interests (64%); specific disclosures vs no disclosure statements (34%); and specific disclosures vs declarations of no interests (2%). Among the 75 authors who disclosed at least 1 relationship with an organization, there were 2 cases (3%) in which the organization was disclosed in every article the author wrote.
Conclusions/Significance
In the rare instances when financial interests were disclosed, they were not disclosed consistently, suggesting that there are problems with transparency in an area of the literature that has important implications for patient care. Our findings suggest that the inconsistencies we observed are due to both the policies of journals and the behavior of some authors
SARchaeologyâDetecting Palaeochannels Based on High Resolution Radar Data and Their Impact of Changes in the Settlement Pattern in Cilicia (Turkey)
The fertile alluvial plain of Cilicia is bordered by the Taurus and Amanus mountain ranges to the west, north and east and the Mediterranean Sea to the south. Since the Neolithic Period, Plain Cilicia was an important interface between Anatolia and the Levant. The alluvial plain is dominated by three rivers: Tarsus, Seyhan and Ceyhan. The avulsion history of the lower course of the rivers Seyhan and Ceyhan during the Holocene remains an unresolved issue. The knowledge about how former river courses have changed is essential for the identification of ancient toponyms with archaeological sites. The analysis of silted up riverbeds based on high-resolution digital elevation models (TanDEM-X) and historic satellite imagery (CORONA) in this paper provide the first indications for the reconstruction of former river channels. Further evidence is given by the evaluation of the settlement patterns from 3rd to 1st millennium BC
Does the Establishment of Sustainable Use Reserves Affect Fire Management in the Humid Tropics?
Tropical forests are experiencing a growing fire problem driven by climatic change, agricultural expansion and forest degradation. Protected areas are an important feature of forest protection strategies, and sustainable use reserves (SURs) may be reducing fire prevalence since they promote sustainable livelihoods and resource management. However, the use of fire in swidden agriculture, and other forms of land management, may be undermining the effectiveness of SURs in meeting their conservation and sustainable development goals. We analyse MODIS derived hot pixels, TRMM rainfall data, Terra-Class land cover data, socio-ecological data from the Brazilian agro-census and the spatial extent of rivers and roads to evaluate whether the designation of SURs reduces fire occurrence in the Brazilian Amazon. Specifically, we ask (1) a. Is SUR location (i.e., de facto) or (1) b. designation (i.e. de jure) the driving factor affecting performance in terms of the spatial density of fires?, and (2), Does SUR creation affect fire management (i.e., the timing of fires in relation to previous rainfall)? We demonstrate that pre-protection baselines are crucial for understanding reserve performance. We show that reserve creation had no discernible impact on fire density, and that fires were less prevalent in SURs due to their characteristics of sparser human settlement and remoteness, rather than their status de jure. In addition, the timing of fires in relation to rainfall, indicative of local fire management and adherence to environmental law, did not improve following SUR creation. These results challenge the notion that SURs promote environmentally sensitive fire-management, and suggest that SURs in Amazonia will require special attention if they are to curtail future accidental wildfires, particularly as plans to expand the road infrastructure throughout the region are realised. Greater investment to support improved fire management by farmers living in reserves, in addition to other fire users, will be necessary to help ameliorate these threats
