    Disserta√ß√£o (mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ci√™ncias Humanas, Programa de P√≥s-Gradua√ß√£o em Geografia, Florian√≥polis, 2011O setor leste catarinense √© caracterizado pela presen√ßa de terrenos elevados, representados por planaltos e seq√ľ√™ncia de serras costeiras subparalelas, cuja altitude superiores a 1000m decresce em dire√ß√£o ao oceano. Este setor est√° freq√ľentemente submetido √† atua√ß√£o dos ciclones extratropicais, que geralmente ocasionam ventos fortes causando preju√≠zos as cidades litor√Ęneas e proximidades. Este trabalho analisa a influ√™ncia dos ciclones extratropicais nas mesorregi√Ķes Serrana e do Leste de Santa Catarina e suas rela√ß√Ķes com a Oscila√ß√£o Decadal do Pac√≠fico (ODP). Os ciclones extratropicais que atuaram nas proximidades do litoral de Santa Catarina, entre 1998 e 2008, foram levantados atrav√©s de um esquema num√©rico identifica√ß√£o e rastreamento de ciclones. A influ√™ncia destes sistemas no comportamento do vento e da precipita√ß√£o foi avaliada atrav√©s de c√°lculos de correla√ß√£o entre a profundidade do ciclone e o vento e a precipita√ß√£o observada em sete esta√ß√Ķes meteorol√≥gicas que est√£o distribu√≠das nas mesorregi√Ķes Serrana e do Leste de Santa Catarina. Os resultados mostraram estatisticamente que n√£o h√° correla√ß√£o da profundidade dos ciclones com a ocorr√™ncia de precipita√ß√£o. Embora os ciclones influenciem a ocorr√™ncia de vento no setor leste de Santa Catarina, √© necess√°rio levar em considera√ß√£o os efeitos locais em torno de cada esta√ß√£o meteorol√≥gica, como relevo, altitude e maritimidade. Quanto √† rela√ß√£o da ocorr√™ncia de ciclones com a ODP verificou-se que durante a fase fria ocorreu um aumento de anomalias negativas de ciclones, e na segunda metade da fase quente um aumento de anomalias positivas. A an√°lise de freq√ľ√™ncia de ocorr√™ncia mostrou que a primavera e ver√£o s√£o as esta√ß√Ķes com um m√°ximo de ocorr√™ncia de ciclones extratropicais, embora exer√ßam pouca influ√™ncia durante o ver√£o em Santa Catarina.The East Sector of the Santa Catarina state is characterized by the presence of elevated terrain such as plateaus, and a sequence of sub-parallel coastal mountain ranges of altitudes above 1000m, which decrease towards the ocean. This sector is often under extratropical cyclones which usually bring high winds and material damage to coastal cities and their proximities. This paper analyzes the influence of extratropical cyclones in the eastern and mountain range mesoregions in the Santa Catarina state, and its relation to the Pacific Decadal Oscillation (PDO). Extratropical cyclones acting in the area of coastal Santa Catarina state between 1998 and 2008 were gathered through a numeric system of cyclone identification and tracking. The influence of such weather systems in the behaviors of wind and precipitation was evaluated through correlation calculations between cyclone depth and wind and precipitation observed in seven weather stations located throughout the mountain range and eastern mesoregions in the Santa Catarina state. Results show statistically that there is no correlation between cyclone depth and precipitation events. Although cyclones do influence wind events in the East sector of the state, local effects in the vicinity of each weather station such as terrain, altitude, and maritime climate, must also be taken into consideration. As regards to the relation between event occurrence and the DPO, it was possible to observe that during the cool phase the number of negative-cyclone anomalies increased, whereas in the second stage of the warm phase the number of positive anomalies increased. The occurrence frequency analysis has shown that the spring and summer seasons have a peak of extratropical cyclone occurrences, albeit having little influence over the state of Santa Catarina during the summer

    The Falklands/Malvinas war, was one of the most striking and surprising warlike events of modern history in many ways. One of the points that proved to be of great importance during the period in which they occurred fighting were extremely adverse weather conditions in the conflict area and their influence over the fighting. The work presented here deals with the case in which the two maritime forces (Argentine and British) composed of the aircraft carrier, were very close to a real confrontation. The situation could have changed the course of future clashes, but was thwarted by the third factor that acted in this relentlessly scenario, the weather. The presence of an anticyclonic system caused an unexpected calm in the winds in the south of the South Atlantic. This condition coupled with strategic factors that occurred simultaneously made it impossible to launch aircraft from carriers, especially in the case of the Argentine ship and thus the forces in combat had to back down waiting for a new ideal opportunity

    Introdu√ß√£o: a fibrose c√≠stica (FC) √© uma doen√ßa autoss√īmica recessiva caracterizada, especialmente, pela alta produ√ß√£o de muco, em raz√£o de uma altera√ß√£o na prote√≠na regulador transmembrana da FC (RTFC). Dentre as comorbidades secund√°rias, a altera√ß√£o no metabolismo lip√≠deo √© impactante e muito discutida e vem-se estudando a interfer√™ncia dessa altera√ß√£o nos processos inflamat√≥rios que ocorrem frequentemente em pacientes fibroc√≠sticos. Objetivo: Avaliar os poss√≠veis efeitos da suplementa√ß√£o de √°cidos graxos poli-insaturados (PUFAs) na fibrose c√≠stica, notadamente do ponto de vista inflamat√≥rio. Metodologia: revis√£o de literatura, com busca sistem√°tica nas bases de dados Pubmed, Science Direct, Bireme e Peri√≥dicos CAPES. Resultados: a suplementa√ß√£o de PUFAs aumenta os n√≠veis s√©ricos de √°cido linoleico e decosahexaenoico e reduz os n√≠veis s√©ricos do √°cido araquid√īnico (AA) e do √°cido Mead. Conclus√£o: j√° foram realizados ensaios cl√≠nicos com pequeno n√ļmero de indiv√≠duos e em curto per√≠odo de tempo, por√©m, ainda n√£o existe um consenso para o protocolo de suplementa√ß√£o de PUFAs. Nos estudos observados, encontraram-se resultados positivos, sugerindo que essa suplementa√ß√£o pode ser um aliado no manejo da doen√ßa, embora sejam necess√°rios mais estudos para melhor esclarecer o mecanismo desse efeito ben√©fico, bem como para estabelecer a melhor dose para suplementa√ß√£o de PUFAs na F

    Hevea brasiliensis (Willd. Ex Adr. Juss.) Muell.-Arg. is the primary source of natural rubber that is native to the Amazon rainforest. The singular properties of natural rubber make it superior to and competitive with synthetic rubber for use in several applications. Here, we performed RNA sequencing (RNA-seq) of H. brasiliensis bark on the Illumina GAIIx platform, which generated 179,326,804 raw reads on the Illumina GAIIx platform. A total of 50,384 contigs that were over 400 bp in size were obtained and subjected to further analyses. A similarity search against the non-redundant (nr) protein database returned 32,018 (63%) positive BLASTx hits. The transcriptome analysis was annotated using the clusters of orthologous groups (COG), gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Pfam databases. A search for putative molecular marker was performed to identify simple sequence repeats (SSRs) and single nucleotide polymorphisms (SNPs). In total, 17,927 SSRs and 404,114 SNPs were detected. Finally, we selected sequences that were identified as belonging to the mevalonate (MVA) and 2-C-methyl-D-erythritol 4-phosphate (MEP) pathways, which are involved in rubber biosynthesis, to validate the SNP markers. A total of 78 SNPs were validated in 36 genotypes of H. brasiliensis. This new dataset represents a powerful information source for rubber tree bark genes and will be an important tool for the development of microsatellites and SNP markers for use in future genetic analyses such as genetic linkage mapping, quantitative trait loci identification, investigations of linkage disequilibrium and marker-assisted selection.9e10266
