Understanding the factors controlling fine root respiration (FRR) at different temporal scales will help to improve our knowledge about the spatial and temporal variability of soil respiration (SR) and to improve future predictions of CO2 effluxes to the atmosphere. Here we present a comparative study of how FRR respond to variability in soil temperature and moisture in two widely spread species, Scots pines (Pinus sylvestris L.) and Holm-oaks (HO; Quercus ilex L.). Those two species show contrasting water use strategies during the extreme summer-drought conditions that characterize the Mediterranean climate. The study was carried out on a mixed Mediterranean forest where Scots pines affected by drought induced die-back are slowly being replaced by the more drought resistant HO. FRR was measured in spring and early fall 2013 in excised roots freshly removed from the soil and collected under HO and under Scots pines at three different health stages: dead (D), defoliated (DP) and non-defoliated (NDP). Variations in soil temperature, soil water content and daily mean assimilation per tree were also recorded to evaluate FRR sensibility to abiotic and biotic environmental variations. Our results show that values of FRR were substantially lower under HO (1.26 ± 0.16 microgram CO2 /groot·min) than under living pines (1.89 ± 0.19 microgram CO2 /groot·min) which disagrees with the similar rates of soil respiration previously observed under both canopies and suggest that FRR contribution to total SR varies under different tree species. The similarity of FRR rates under HO and DP furthermore confirms other previous studies suggesting a recent Holm-oak root colonization of the gaps under dead trees. A linear mixed effect model approach indicated that seasonal variations in FRR were best explained by soil temperature (p<0.05) while soil moisture was not exerting any direct control over FRR, despite the low soil moisture values during the summer sampling. Plant assimilation rates were positively related to FRR explaining part of the observed variability (p<0.01). However the positive relations of FRR with plant assimilation occurred mainly during spring, when both soil moisture and plant assimilation rates were higher. Our results finally suggest that plants might be able to maintain relatively high rates of FRR during the sub-optimal abiotic and biotic summer conditions probably thanks to their capacity to re-mobilize carbon reserves and their capacity to passively move water from moister layers to upper layers with lower water potentials (where the FR were collected) by hydraulic lift.

The present study examines the repertory of liturgical chant known as St. Petersburg Court Chant which emerged within the Imperial Court of St. Petersburg, Russia, and appeared in print in a number of revisions during the course of the 19th century, eventually to spread throughout the Russian Empire and even abroad. The study seeks answers to questions on the essence and composition of Court Chant, its history and liturgical background, and most importantly, its musical relationship to other repertories of Eastern Slavic chant. The research questions emerge from previous literary accounts of Court Chant (summarized in the Introduction), which have tended to be inaccurate and generally not based on critical research. The study is divided into eight main chapters. Chapter 1 provides a survey of the history of Eastern Slavic chant and the Imperial Court Chapel of St. Petersburg until 1917, with special emphasis on the history of singing traditional chant in polyphony, the status of the Court Chapel as a government authority, and its endeavours in publishing church music. Chapter 2 deals with the liturgical background of Eastern chant, the chant genres, and main repertories of Eastern Slavic chant. Chapter 3 concentrates on chant sources: it introduces the musical notations utilised, after which a typology of chant books is presented. The discussion continues with a survey of the sources of Court Chant and their content, the specimens selected for closer analysis, the comparative materials from other repertories, and ends with a commentary on some chant sources that have been excluded. The comparative sources include a specimen from around the beginning of the 12th century, a few manuscripts from the 17th century, and printed and manuscript chant books from the early 18th to early 20th century, covering the geographical area that delimits to the western Ukraine, Astrakhan, Nizhny Novgorod, and the Solovetsky Monastery. Chapter 4 presents the approach and methods used in the subsequent analytical comparisons. After a survey of the pitch organization of Eastern Slavic chant, the customary harmonization strategy of traditional chant polyphony is examined, according to which a method for meaningful analysis of the harmony is proposed. The method is based on the observation that the harmonic framework of chant polyphony derives from the standard pitch collection of monodic chant known as the Church Gamut, specific pitches of which form eight harmonic regions that behave like the usual tonalities of major and harmonic minor. Because of the considerable quantity of comparative chant forms, computer-assisted statistical methods are applied to the analysis of chant melodies. The primary chant forms and their respective comparative forms have been pre-processed into reduced chant prototypes and divided into redactions. The analyses are carried out by measuring the formal dissimilarities of the primary chant forms of the Court Chant repertory against each comparative form, and also by measuring the reciprocal dissimilarities of all chant versions in a redaction, the results of which are subjected to agglomerative hierarchical clustering in order to find out how the chant forms relate to each other. The dissimilarities are determined by applying a metric dissimilarity function that is based on the Levenshtein Distance. Chapter 5 provides the melodic and harmonic analyses of generic chants (chants used for multiple texts of different lengths), i.e., chants for stichera samoglasny and troparia, Chapter 6 of pseudo-generic chants (chants that are used for multiple texts but with certain restrictions), i.e., chants for heirmoi, prokeimena, and three other hymns, and Chapter 7 of non-generic chants, covering nine chants that in the Court repertory are not shared by multiple texts. The results are summarized and evaluated in Chapter 8. Accordingly, it can be established that, contrary to previous conceptions, melodically, Court Chant is in effect a full part of the wider Eastern Slavic chant tradition. Even if it is somewhat detached from the chant versions of the Synodal square-note chant books and the local tradition of Moscow, it is particularly close to chant forms of East Ukraine and some vernacular repertories from Russia. Respectively, the harmonization strategies of Court Chant do not show significant individuality in comparison with those of the available polyphonic comparative sources, the main difference being the part-writing, which generally conforms to western common practice standard, whereas the deviations from this tend to be more significant in other analysed repertories of polyphonic chant. Thus, insofar as the subsequent prevalence of Court Chant is not based on its forceful dissemination by authorities (as suggested in previous literature but for which little tangible evidence could be found in Chapter 1), in the present author’s interpretation, Court Chant attained its dominance principally because musically it was considered sufficiently traditional, and as a chant body supported by the government, was conveniently available in print in serviceable harmonizations.

Estudo conduzido com o objetivo de avaliar a confiabilidade, acurácia e dificuldades do exame de congelação, utilizando-se pequenos fragmentos de tumores mamários obtidos com a biópsia histológica por agulha grossa (bioptycut). Durante 13 meses, 37 pacientes foram submetidas ao Bioptycut (pistola BIP 2.2 ou Promag 1.2, agulhas l4G), sendo que, de cada uma delas, foram retirados no mínimo dois fragmentos, um a fresco para congelação e outro submerso em formol para inclusão posterior em parafina. O estudo de congelação constituiu-se de exame citológico do "imprimir" da peça e de exame histológico usando cortes através de congelação. Os cortes foram feitos usando criostato e micrótomo, com cortes de 8µ. O tamanho do tumor puncionado variou de 1cm a 12cm (média 4,8cm). A congelação foi conclusiva em 33 casos (89%), sendo trinta carcinomas e três benignos, e inconclusiva em quatro casos (11%). A obtenção deste dia:nóstico se deu pelo "imprint" e corte em 29 casos (78%), só pelo "imprint" em quatro casos (11 %), em dois casos tanto o corte quanto o "imprint" foram inadequados e dois não foram descritos. Posteriormente foram obtidas peças por exérese da lesão (até a análise) em 28 casos, dos quais 25 carcinomas e três tumores benignos (11 %). Houve um caso de congelação conclusiva de benignidade, em que a exérese posterior revelou se tratar de carcinoma (falso-negativo). Não houve falsos-positivos. A sensibilidade foi de 96% e a especificidade de 100%. Assim, conclui-se que o exame por congelação, usando-se peças obtidas com bioptycut se mostrou confiável, evitando biópsias abertas em 81 % dos casos, garantindo rapidez e melhor preparo das pacientes para terapêutica definitiva.

OBJETIVO: Descrever os casos de câncer de mama nas mulheres residentes em Goiânia no período 1989-2003. MÉTODOS: Estudo retrospectivo, descritivo, que incluiu todos os casos de câncer de mama ocorridos nas moradoras de Goiânia, identificados pelo Registro de Câncer de Base Populacional de Goiânia (RCBPGO), no período de 1989 a 2003. As variáveis estudadas foram: idade, método de diagnóstico, localização topográfica, morfologia e extensão do câncer de mama. Foram utilizadas frequências e taxas percentuais, além da regressão de Poisson para determinação da mudança percentual anual (MPA). RESULTADOS: Foram identificados 3204 casos de câncer de mama. A localização topográfica mais frequente foi o quadrante superior lateral (53,7%). O carcinoma ductal infiltrante (CDI) foi o mais freqüente, com 2582 casos (80,6%), seguido pelo carcinoma lobular infiltrante (CLI), com 155 casos (4,8%). Houve aumento significante tanto do CDI quanto do CLI, sendo a MPA de 11,0 % e de 15,4%, respectivamente. A proporção entre CDI e CLI não foi influenciada pela idade (p=0,98). Quanto à extensão do tumor ao diagnóstico, 45,6% dos casos eram localizados na mama, sendo que a MPA foi de 16,1% (IC= 12,4 a 20,0; p<0,001). Houve tendência de redução da MPA dos casos metastáticos (-3,8; IC= -8,6 a 1,2; p=0,12). CONCLUSÃO: A localização topográfica e o tipo histológico do câncer de mama, na cidade de Goiânia, seguem o padrão de outros países. Os principais tipos morfológicos não foram influenciados pela idade. Houve grande aumento de casos iniciais.

Objetivos: avaliar o nível de conhecimento de noções básicas do diagnóstico do câncer de mama entre os alunos de medicina; promover a discussão entre eles e avaliar o aproveitamento dos alunos do 5º ano médico, após cursar a Disciplina de Ginecologia. Métodos: por meio de questionários aplicados a 348 alunos do total de 550 alunos, do 1º ao 5º ano do curso médico, buscaram-se informações a respeito do conhecimento básico do diagnóstico do câncer de mama. Dos 348 questionários aplicados, 55 (16%) foram respondidos por estudantes do 5º ano que haviam cursado a Disciplina de Ginecologia. Destes, 43% eram mulheres, 62% tinham familiares médicos e 17% história familiar de câncer de mama. Resultados: em relação ao conhecimento dos métodos diagnósticos, 84% dos alunos acertaram o sinal mais freqüente do câncer de mama; 34%, o melhor método de rastreio; 49%, quando indicar a mamografia em mulheres assintomáticas; 37%, a periodicidade preconizada da mamografia após 50 anos e 24%, quando associar o ultra-som à mamografia para detecção do câncer de mama. Os alunos do 5º ano apresentaram um índice de acerto para todas as perguntas significativamente maior que os demais. O sexo só apresentou diferença em relação ao maior conhecimento pelas mulheres quanto ao melhor período para o auto-exame e quando indicar a associação do ultra-som à mamografia. A presença de familiares médicos e a história familiar de câncer de mama não influenciaram as respostas. Conclusão: mesmo entre acadêmicos de medicina ainda é grande a desinformação a respeito do diagnóstico do câncer de mama. Não obstante, após cursar a disciplina, esse conhecimento aumenta significativamente.

Objetivo: avaliar o nível de conhecimento e prática do auto-exame da mama entre os estudantes do curso médico e determinar possíveis fatores associados a esta prática. Métodos: foi utilizado um questionário que continha informações sobre os alunos e o seu conhecimento a respeito do auto-exame, permitindo ainda, verificar entre as alunas a prática do mesmo. Utilizaram-se os testes do qui quadrado e "t" de Student, quando aplicáveis, para verificar a associação de alguns fatores com o auto-exame. Resultados: dos 348 questionários respondidos, 55 (16%) pertenciam aos alunos do 5º ano (estudantes que haviam cursado a Disciplina de Ginecologia da Universidade Federal de Goiás), 43% eram mulheres, 62% tinham familiares médicos e 17% apresentavam história familiar de câncer de mama. Em relação ao conhecimento do auto-exame, 95% conheciam o método. Das 149 estudantes, apenas 64% o praticavam. Os motivos para não fazê-lo eram: por ser muito jovem (24%), por não acreditar que pudesse acontecer com ela (4%), por medo (9%) e por preguiça (19%), sendo que 44% das alunas não souberam explicar o motivo. Tanto o conhecimento quanto a prática do auto-exame não estiveram associados ao ano do curso médico, história familiar de câncer de mama ou à presença de familiar médico. Conclusão: o auto-exame é conhecido por praticamente todos os estudantes de medicina mesmo assim, um terço das estudantes não o praticam. Com isso ressalta-se a importância do auto-exame no curso médico, a fim de que os alunos possam levar mais informações à população, não limitando esta tarefa aos meios de comunicação.

OBJETIVO: Analisar a mudança temporal do estádio clínico do câncer de mama ao diagnóstico em mulheres residentes em Goiânia entre 1989 e 2003. MÉTODOS: estudo retrospectivo, utilizando-se a base de dados do Registro de Câncer de Base Populacional de Goiânia. As variáveis estudadas foram: idade, diagnóstico histológico, localização do tumor, tipo histológico e estádio clínico da doença. O período estudado foi dividido em três quinquênios: de 1989 a 1993, de 1994 a 1998 e de 1999 a 2003. Utilizou-se o teste Z para comparação das frequências da extensão ao diagnóstico por quinquênio. RESULTADOS: foram identificados 3.204 casos de câncer de mama. A média de idade foi de 56 anos (dp±16 anos). Quanto ao estádio da doença, evidenciou-se que 45,6% dos casos eram localizados na mama, com aumento de 19,2% entre o primeiro e o terceiro quinquênio (p<0,001; IC95%=0,14-0,23) e 10,2% de casos eram metastáticos, Entretanto, foi observada uma redução de 17,7% para os casos metastáticos no mesmo período (p<0,001; IC95%=0,14-0,21). A taxa de casos in situ entre 1989 e 1993 foi de 0,2%, aumentando para 6,2% em 1999-2003 (p<0,001; IC95%=4,9-7,4). CONCLUSÃO: observou-se um aumento dos casos de carcinoma in situ e de carcinomas invasores localizados somente na mama em detrimento de uma redução dos casos com metástases linfonodais e à distância.

Advanced oxidation processes (AOPs) have been studied and developed to suffice the effective removal of refractory and toxic compounds in polluted water. The quality and cost of wastewater treatment need improvements, and electric discharge technology has a potential to make a significant difference compared to other established AOPs based on energy efficiency. The generation of active oxidant species such as ozone and hydroxyl radicals by high voltage discharge is a relatively new technology for water treatment. Gas-phase pulsed corona discharge (PCD), where a treated aqueous solution is dispersed between corona-producing electrodes free of the dielectric barriers, was developed as an alternative approach to the problem. The short living radicals and ozone formed in the gas phase and at the gas-liquid interface react with dissolved impurities. PCD equipment has a relatively simple configuration, and with the reactor in an enclosed compartment, it is insensitive towards gas humidity and does not need the gas transport. In this thesis, PCD was used to study and evaluate the energy efficiency for degrading various organic compounds, as well as the chemistry of the oxidation products formed. The experiments investigate the aqueous oxidation of phenol, humic substances, pharmaceutical compounds (paracetamol, ibuprofen, indomethacin, salicylic acids, -estradiol), as well as lignin degradation and transformation to aldehydes. The study aims to establish the influence of initial concentration of the target pollutant, the pulsed discharge parameters, gas phase composition and the pH on the oxidation kinetics and the efficiency. Analytical methods to measure the concentrations of the target compounds and their by-products include HPLC, spectrophotometry, TOC and capillary electrophoresis. The results of the research included in this summary are presented in the attached publications and manuscripts accepted for publication. Pulsed corona discharge proved to be highly effective in oxidizing each of the target compounds, surpassing the closest competitor, conventional ozonation. The increase in oxidation efficiencies for some compounds in oxygen media and at lower pulse repetition frequencies shows a significant role of ozone. The role of the ·OH radicals was established in the surface reactions. The main oxidation products, formation of nitrates, and the lignin transformation were quantified. A compound specific approach is suggested for optimization of the PCD parameters that have the most significant impact on the oxidation energy efficiency because of the different characteristics and responses of the target compound to the oxidants, as well as different admixtures that are present in the wastewater. Further studies in the method’s safety (nitration and nitrosation of organic compounds, nitrite and nitrate formation enhancement) are needed for promoting the method.
