CONJUNTURA POLíTICA BRASILEIRA, A GEOGRAFIA E A AGB
Adauto de Oliveira Souza
Boletim Goiano de Geografia , 2006,
Abstract: Neste artigo fizemos uma análise da atual conjunturapolítica brasileira incorporando discuss es relativas àatua o da AGB. A análise da realidade brasileira, demonstraque o País se defronta, internamente, comimensos problemas e, ideologicamente, propala-se,que em decorrência há necessidade de reformas. Taisreformas envolvem diversas dimens es da realidade nacional,desde, economicamente, a supera o do modeloneoliberal, até as reformas política, urbana, universitária,entre outras. E, mesmo no interior da AGB, também sefala em reforma estatuária. Estamos diante de uma conjunturana qual a forma o da Na o, como o espa o dedisputa do sentido político comum é substituída por umconsenso for ado. é a política como administra o. Nessecontexto, uma das principais mudan as refere-se aopapel do Estado. A AGB, por sua vez, tem a sua atua orelacionada com as condi es materiais da sociedadebrasileira: aristocraticamente, criada em 1934, efetivamentese nacionalizou nos anos de 1940, democratizando-se a partir dos anos 80, momento em que passou aconstituir-se num referencial político, além de científicoe cultural em todo o País. Mesmo diante dessa constata o,consideramos que o desafio de repensar a entidadedeve ser permanente para que a AGB continue dando suacontribui o para a democratiza o do conhecimento geográficoe o fortalecimento da categoria profissional.

Abstract: FUNDAMENTOS: A infec o por dermatófitos afeta aproximadamente 40% da popula o mundial, representa 30% de todas as infec es micóticas cutaneas, e a onicomicose por dermatófito é a mais freqüente, representando entre 18 e 40% de todas as onicopatias. A onicomicose é causada primariamente por dermatófitos, Candida spp. e outros fungos n o dermatófitos. Entre os agentes fúngicos, os dermatófitos, particularmente Trichophyton rubrum, s o os mais comuns desses patógenos. Atualmente, Candida spp. pode invadir a unha distal e proximal. As onicomicoses provocadas por fungos n o dermatófitos vêm aumentando em sua prevalência, e, pela similaridade clínica com a onicomicose por dermatófito, é necessário o diagnóstico laboratorial para sua diferencia o. OBJETIVOS: O objetivo do presente trabalho é avaliar a ocorrência de onicomicose na cidade do Rio de Janeiro. MéTODOS: Foram avaliados 2.920 pacientes entre janeiro de 1998 e dezembro de 1999, dos quais 1.416 apresentaram anormalidades nas unhas. RESULTADOS: A confirma o micológica de onicomicose foi possível em 565 dos 2.920 pacientes, e a prevalência estimada pontual na cidade do Rio de Janeiro é 19,34%. Os homens foram responsáveis por 34,16% das onicomicoses, e as mulheres por 65,84%. A distribui o por agente etiológico dos 224 pacientes com onicomicose que apresentaram cultura positiva foi: dermatófitos 64,7%, Candida spp. 30,1% e outros n o dermatófitos 5,2%. CONCLUS O: A microbiota fúngica é completamente trocada no mundo periodicamente em sua composi o quantitativa e qualitativa, sendo afetada por vários fatores ambientais. Assim, o exame periódico da composi o desta microbiota vem a ser vantajoso e de importancia epidemiológica e terapêutica.

Abstract: FUNDAMENTOS: As dermatomicoses causadas por fungos emergentes s o entidades clínicas raras, à exce o das onicomicoses. Como certos fungos e leveduras podem residir na pele, a positividade em culturas de escamas ungueais deve ser interpretada obrigatoriamente em concordancia com os respectivos dados clínicos, exames diretos das amostras, quantifica o das col nias isoladas em rela o aos pontos de inocula o e, principalmente, deve a positividade ser mantida após a repeti o dos cultivos. A invas o da unha por fungos n o dermatofíticos (nondermatophytic molds, NDM) em diferentes estudos varia de 1,45% a 17,6%. OBJETIVOS: Os objetivos do trabalho s o mostrar a ocorrência e real ar a importancia dos fungos emergentes como causadores de onicomicose. MéTODOS: As unhas dos pacientes atendidos nos consultórios dos dermatologistas foram examinadas, e, caso houvesse suspeita clínica de onicomicose, coletavam-se amostras que eram enviadas para exame micológico no laboratório. RESULTADOS: Neste estudo, foram avaliados 2.271 pacientes e diagnosticada onicomicose em 400 deles, sendo 264 com acometimento das unhas do pé, e 136 das unhas da m o. O agente etiológico foi confirmado pelo exame micológico direto e crescimento em cultura. A onicomicose por fungos emergentes representou 4,5% de todas as infec es de unha. Foram detectadas as leveduras do gênero Candida (49%) como agentes etiológicos mais freqüentes de onicomicoses nas unhas das m os e em mulheres. Em contraste, os dermatófitos foram os mais freqüentes de todas as onicomicoses dos pés, no total de 186 (46,5%). CONCLUS O: Ao contrário da rotina diagnóstica hoje utilizada, concluiu-se que o diagnóstico correto do agente etiológico da onicomicose n o dermatofítica deve obedecer a determinados critérios, dos quais se destaca o conjunto formado pela positividade no exame direto, na cultura, com comprova o na repeti o do exame.

Abstract: peat was taken from the sergipe state, brazil and characterized by several techniques: elemental and thermal analyses; fourier infrared (ftir) and solid state 13c nuclear magnetic resonance (nmr) spectroscopies; scanning electron microscopy (sem), environmental scanning electron microscopy (esem) and x-ray diffractometry (xrd). also, the sergipe state peat samples were compared with other peat sample from later from sao paulo state, brazil. the lowest o/c and e4/e6 ratios and differential thermal analysis (dta) curves of the santo amaro (sao) sample indicated that this sample had the highest degree of decomposition. ftir results showed that itabaiana (ita) and s?o paulo (sap) samples presented more prominent peak at 1086 cm-1 attributed the presence of si-o than sao sample spectra. the sao sample showed two more intense peaks at 2920 cm-1 and 2850 cm-1. these results were corroborated by 13c nmr and thermal gravimetric (tg) where the relative abundance of the alkyl-c groups was greater in the sao sample. the x-ray diffractometry (xrd) of sao sample is characteristic of amorphous matter however, the sap and ita samples revealed the large presence of quartz mineral. the scanning electron microscopy (sem) and environmental scanning electron microscopy (esem) showed that the surface of peat samples have porous granules of organic material. the ita and sap peat samples are alike while sao peat sample is richer in organic material. only the sao sample has truthful characteristics of peat. the results of this study showed that the samples are very different due to variable inorganic and organic material contents.

Abstract: the experiment was carried out in the sheep division of universidade federal de lavras, aiming to evaluate the effect of different concentrate : voluminous ratio on the performance of santa inês lamb after wean. 40 lambs, male uncastrated, were used and fed with four different diets: diet a (100% concentrate), diet b (75:25 concentrate : voluminous) , diet c (50:50 concentrate : voluminous) , diet d (25:75 concentrate : voluminous). the experimental diets were isoproteic, differing only on its levels of concentrate : voluminous and balanced to meet the nutritional demands according to the recommendation of the agricultural research council (1980). the experimental period was not pre-established, because it corresponded to the necessary period for the last lamb to reach the live weight of 35kg. the dry matter consumption (dmc), crude protein consumption (cpc), fiber in neutral detergent consumption (fndc) and fiber in acid detergent consumption (fadc), were affected by the different concentrate : voluminous ratio, in which, the animals that received diets with higher concentrate inclusion presenting better results for the variables related to the development. the lambs fed with the diet containing higher inclusion of voluminous did not present weight gain, on the contrary, presented weight loss, since none of the animals reached slaughter weight and the mortality rate was extremely high (80%).

Abstract: one of the crucial steps of authentication of adna sequences is phylogenetic consistency. amplified sequences should fit into the phylogenetic framework of their supposed origin. an inherent property of adna sequences however, is their short sequence length. additionally, genes for adna studies are often chosen by their preservation potential rather than by phylogenetically informative content. this poses potential challenges regarding their analyses, and might result in an inaccurate reflection of the supposed phylogenetic history of the sequence or organism under study. in this paper some fundamental problems of phylogenetic analysis and interpretation of adna datasets are discussed. suggestions for character sampling and treatment of missing data are made. the publication is the result of a talk from the 1st paminsa meeting in rio de janeiro, july 2005.

Abstract: the serra de itabaiana national park is distinguished by its phytophysiognomic diversity, among which, a locally known as areias brancas (white sands), an open vegetation, ranging from herb-shrub to shrub-tree and classified by some authors as restinga or cerrado, depending on its size. aiming to characterize and classify vegetational type were selected two sites in areias brancas of serra de itabaiana national park and built a list following deposited material in the ase herbarium and additional sampling. to the phytosociological study it was used the wandering quarter method, sampling all individuals with trunk circumference (> 15 cm) at breast height (1.30 m). it was verified, at the areias brancas, the occurrence of 193 species belonging to 145 genera and 60 families that are mostly represented by herb and shrub species. it is noticeable the high number of species found in areias brancas when compared with studies conducted throughout the national park. there are significant floristic similarity between sampling sites, but structurally the two areas should be considered as different sucessional faces, due to variations in density, height and dominance. even with plant species in common, the areias brancas of the national park can not be classified as restinga or cerrado for not having common origins for these formations. the areias brancas should be considered as an ecological refuge, an azonal vegetation derived from the special conditions of substrate formation.

Abstract: Estudos de estrutura de tamanho e de estágios ontogênicos s o importantes para se compreender quais fatores influenciam os processos populacionais, a regenera o e a resposta a perturba es de uma popula o. Este estudo analisou a estrutura de uma popula o de Kielmeyera rugosa Choisy (Clusiaceae) no hábitat de Areias Brancas do Parque Nacional Serra de Itabaiana, Estado de Sergipe. Amostraram-se aleatoriamente 30 parcelas de 20 x 25 m, nas quais se determinou a abundancia de indivíduos jovens e adultos, a circunferência do tronco, a altura da copa e o número de caules por planta. A distribui o espacial de jovens e adultos na popula o é agregada, causada por sua predisposi o em formar grupos em locais onde há maiordisponibilidade de recursos e condi es favoráveis. Outro fator que contribui com a agrega o é a dispers o anemocórica da espécie. A popula o estudada apresentou o maior número de indivíduos nas categorias menores de altura e de DAS, indicando que a popula o está em crescimento ou em processo de autorregenera o. Há maior número de indivíduos de 2-3 m de altura, o que se deve ao fogo ou corte, eventos que n o foram capazes de interromper o processo de recrutamento ou reprodu o da espécie na área, pois n o ocorreram lacunas nas classes de diametro de caule. Studies on structure, size and ontogenic stages are important to understand which factors influence population processes, regeneration and response to disturbances of a population. This study examined thestructure of a population of Kielmeyera rugosa Choisy (Clusiaceae) in white sands habitat of Serra de Itabaiana, Sergipe State. Thirty 20 x 25 m plots were selected randomly selected, and their abundance of young and adult plants was recorded, as well as trunk circumference, crown height and number of stems per plant. The spatial distribution of young and adult population is aggregated, caused by their predisposition to form groups in localities with large availability of resources and favorable conditions. Another factor contributing to the aggregation is the anemochoric dispersion of the species. The study population had the highest number of individuals in lower classes of height, with few individuals in larger classes, indicating that the population is growing or in a process of selfregeneration.There are more individuals 2-3 meters high, due to burning or cutting. These events were not able to stop the recruitment process or reproduction of the species in the area, as observed by the lack of gaps in the classes of stem diameter.
