Ühis- ning erijooni Soome ja Eesti Kaitseliitude puhkpillimuusikas aastatel 1925-1934.

This study focuses on the similarities and differences between the Estonian Defence League and the Finnish Civil Guard brass bands during the period 1925-1934. By 1934 this paramilitary volunteer state defence organisation had reached stability in its development, such that social, cultural and patriotic education of the people - with the help of brass band music among other means- had acquired a significant role, in addition to prioritised military and sports activities. The study begins with introductory paragraphs I and II, which describes the founding of the organisations, their participation in the Wars of Independence and their subsequent peace time activities as well as their representation in the media at the time. The thesis also briefly introduces military music in Finland and Estonia, as well as describes the influence of military music on the Defence League brass bands. The period under review includes the global economic crisis, which undoubtedly concerned the Defence League/Civil Guard and the Lapua and War of Independence movements, which greatly affected the apolitical principles of the organisations. The main emphasis of the thesis is the Defence League/Civil Guard brass band`s musical activities in two counties - Etelä-Pohjanmaa and Pärnumaa, while also including a general overview of the Estonian Defence League brass bands´ activities. One of the most important benefits of the thesis is its introduction of the brass band repertoire in use at the time, which was played by both professional and as well as amateur orchestras the latter of which also included the brass bands of the Defence League/Civil Guard and the Fire Services. Brass band music held a secondary, yet significant position in the Defence League/Civil Guard, where the orchestra as a musical grouping was obliged to perform not only at inner-organisational and national celebrations but also at any event requiring brass band music, such as song festivals, singing days, and other local cultural events. The professional preparation of the band conductors at the beginning of the period under review was not well specialised, but the training of the Defence League/Civil Defence brass band conductors was carried out regularly in both republic according to the opportunities and dedicated training programmes available. The musicians of the Defence League/Civil Defence brass bands were at the same time members of the military organisations as well as amateur musicians, which placed upon them extra demands - they were under close public supervision in all situations. Based on the principle of chronology it appeared that both Finnish and Estonian respective organisations´ brass bands used the gradually improving economic situation for purchasing musical instruments, obtaining repertoire and training musicians/conductors. Despite the fact that brass band music in the Defence League/Civil Guard was considered an amateur activity and a hobby, the more far-reaching objective of the organisation was to resemble the Defence Forces´ orchestras as closely as possible in all aspects. The Defence League/Civil Guard brass band music definitely had a significant influence on forming, developing and enriching music life in both republics. The reviewed nine-year period introduced the musical activities of the Defence League/Civil Guard against the background of the everyday life of the organisation and the need for brass band music and its continuity in the voluntary state defence institutions of both republics.

High precision Mg isotope measurements of meteoritic samples by secondary ion mass spectrometry

The possibility of establishing an accurate relative chronology of the early solar system events based on the decay of short-lived Al-26 to Mg-26 (half-life of 0.72 Myr) depends on the level of homogeneity (or heterogeneity) of Al-26 and Mg isotopes. However, this level is difficult. to constrain precisely because of the very high precision needed for the determination of isotopic ratios, typically of +/- 5 ppm. In this study, we report for the first time a detailed analytical protocol developed for high precision in situ Mg isotopic measurements ((25)mg/(24)mg and (26)mg/Mg-24 ratios, as well as Mg-26 excess) by MC-SIMS. As the data reduction process is critical for both accuracy and precision of the final isotopic results, factors such as the Faraday cup (FC) background drift and matrix effects on instrumental fractionation have been investigated. Indeed these instrumental effects impacting the measured Mg-isotope ratios can be as large or larger than the variations we are looking for to constrain the initial distribution of Al-26 and Mg isotopes in the early solar system. Our results show that they definitely are limiting factors regarding the precision of Mg isotopic compositions, and that an under- or over-correction of both FC background instabilities and instrumental isotopic fractionation leads to important bias on delta Mg-25, delta(26)mg and Delta Mg-26 values (for example, olivines not corrected for FC background drifts display Delta Mg-26 values that can differ by as much as 10 ppm from the truly corrected value). The new data reduction process described here can then be applied to meteoritic samples (components of chondritic meteorites for instance) to accurately establish their relative chronology of formation.

Seasonal variability of rainfall recorded in growth bands of the Giant African Land Snail Lissachatina fulica (Bowdich) from India

Seasonal rainfall patterns in Bangalore, India, have been reconstructed using stable isotopic ratios in the growth bands of Giant African Land Snail shells. The present study was conducted at Bangalore, India which receives rain during the summer months. The oxygen isotopic record in the rainwater samples collected during different months covering the period of the summer monsoon of the year 2008 is compared with the isotopic ratio in the gastropod growth bands deposited simultaneously. The chronology of the shell growth band is independently established assuming the growth rate observed in a chamber experiment maintaining similar relative humidity and temperature conditions. A consistent pattern observed in the isotopic ratio in the gastropod growth bands and rainwater is demonstrated and provides a novel approach for precipitation reconstruction at seasonal and weekly time scales. This approach of using isotopic ratios in the gastropod growth bands for rainfall can serve as a substitute for filling gaps in rainfall data and for cases where no rain records are available. In addition, they can be used to determine the frequencies and magnitudes of dry spells from the past records. (C) 2013 Elsevier B.V. All rights reserved.

Sheltered coastal environments as archives of paleo-tsunami deposits: Observations from the 2004 Indian Ocean tsunami

The 2004 earthquake left several traces of coseismic land deformation and tsunami deposits, both on the islands along the plate boundary and distant shores of the Indian Ocean rim countries. Researchers are now exploring these sites to develop a chronology of past events. Where the coastal regions are also inundated by storm surges, there is an additional challenge to discriminate between the deposits formed by these two processes. Paleo-tsunami research relies largely on finding deposits where preservation potential is high and storm surge origin can be excluded. During the past decade of our work along the Andaman and Nicobar Islands and the east coast of India, we have observed that the 2004 tsunami deposits are best preserved in lagoons, inland streams and also on elevated terraces. Chronological evidence for older events obtained from such sites is better correlated with those from Thailand, Sri Lanka and Indonesia, reiterating their usefulness in tsunami geology studies.

Cells Producing Their Own Nemesis: Understanding Methylglyoxal Metabolism

Methylglyoxal, which is technically known as 2-oxopropanal or pyruvaldehyde, shows typical reactions of carbonyl compounds as it has both an aldehyde and a ketone functional group. It is an extremely cytotoxic physiological metabolite, which is generated by both enzymatic and nonenzymatic reactions. The deleterious nature of the compound is due to its ability to glycate and crosslink macromolecules like protein and DNA, respectively. However, despite having toxic effects on cellular processes, methylglyoxal retains its efficacy as an anticancer drug. Indeed, methylglyoxal is one of the well-known anticancer therapeutic agents used in the treatment. Several studies on methylglyoxal biology revolve around the manifestations of its inhibitory effects and toxicity in microbial growth and diabetic complications, respectively. Here, we have revisited the chronology of methylglyoxal research with emphasis on metabolism of methylglyoxal and implications of methylglyoxal production or detoxification on bacterial pathogenesis and disease progression.

Optically Stimulated Luminescence (OSL) Dating of Sediments from Himalaya

Optically Stimulated Luminescence (OSL) dating gives the age of most recent daylight exposure or heating of samples to >400 degrees C or the formation events of authigenic minerals. These correspond to the age of sedimentation and burial, ages of thermal events like contact heating by lava flows and heating during faulting and sand dyke formation, and the formation of a mineral via chemical precipitation. With the first observation of OSL in 1985, this method now occupies centre stage in Quaternary Geochronology. The use of OSL method for sediments from Himalaya began over three decades ago. The method has since provided chronology for a variety of events, such as past glaciation events, formation ages of river terraces, paleo-lacustrine deposits, landslides, floods, seismic events with substantive new insights into timing and style of geological processes. Theoretically, the dating range of method is present to a Million years, and this critically depends on two factors, viz, luminescence properties of mineral and their radiation environments. The general working range using quartz is 200ka, and using feldspars is up to Brunhes Matuyam Boundary. Extensions beyond this limit are currently being explored.

[ES] En este trabajo se analizan los glacis de la Cuenca de Miranda, en la que constituyen una de las morfologías de mayor relevancia paisajística. Se han establecido dos niveles de glacis cuyas características topográficas, morfológicas y sedimentológicas se integran plenamente dentro de los rasgos propios de estas morfologías. El significado ambiental de estas formaciones y su correlación con los depósitos aluviales del Ebro, han permitido establecer un marco cronológico para ambos niveles, asociando su génesis a los estadios isotópicos 2 y 4, y todo ello dentro de un marco regional coherente.

Damage detection in civil structures using high-frequency seismograms

The dynamic properties of a structure are a function of its physical properties, and changes in the physical properties of the structure, including the introduction of structural damage, can cause changes in its dynamic behavior. Structural health monitoring (SHM) and damage detection methods provide a means to assess the structural integrity and safety of a civil structure using measurements of its dynamic properties. In particular, these techniques enable a quick damage assessment following a seismic event. In this thesis, the application of high-frequency seismograms to damage detection in civil structures is investigated.

Two novel methods for SHM are developed and validated using small-scale experimental testing, existing structures in situ, and numerical testing. The first method is developed for pre-Northridge steel-moment-resisting frame buildings that are susceptible to weld fracture at beam-column connections. The method is based on using the response of a structure to a nondestructive force (i.e., a hammer blow) to approximate the response of the structure to a damage event (i.e., weld fracture). The method is applied to a small-scale experimental frame, where the impulse response functions of the frame are generated during an impact hammer test. The method is also applied to a numerical model of a steel frame, in which weld fracture is modeled as the tensile opening of a Mode I crack. Impulse response functions are experimentally obtained for a steel moment-resisting frame building in situ. Results indicate that while acceleration and velocity records generated by a damage event are best approximated by the acceleration and velocity records generated by a colocated hammer blow, the method may not be robust to noise. The method seems to be better suited for damage localization, where information such as arrival times and peak accelerations can also provide indication of the damage location. This is of significance for sparsely-instrumented civil structures.

The second SHM method is designed to extract features from high-frequency acceleration records that may indicate the presence of damage. As short-duration high-frequency signals (i.e., pulses) can be indicative of damage, this method relies on the identification and classification of pulses in the acceleration records. It is recommended that, in practice, the method be combined with a vibration-based method that can be used to estimate the loss of stiffness. Briefly, pulses observed in the acceleration time series when the structure is known to be in an undamaged state are compared with pulses observed when the structure is in a potentially damaged state. By comparing the pulse signatures from these two situations, changes in the high-frequency dynamic behavior of the structure can be identified, and damage signals can be extracted and subjected to further analysis. The method is successfully applied to a small-scale experimental shear beam that is dynamically excited at its base using a shake table and damaged by loosening a screw to create a moving part. Although the damage is aperiodic and nonlinear in nature, the damage signals are accurately identified, and the location of damage is determined using the amplitudes and arrival times of the damage signal. The method is also successfully applied to detect the occurrence of damage in a test bed data set provided by the Los Alamos National Laboratory, in which nonlinear damage is introduced into a small-scale steel frame by installing a bumper mechanism that inhibits the amount of motion between two floors. The method is successfully applied and is robust despite a low sampling rate, though false negatives (undetected damage signals) begin to occur at high levels of damage when the frequency of damage events increases. The method is also applied to acceleration data recorded on a damaged cable-stayed bridge in China, provided by the Center of Structural Monitoring and Control at the Harbin Institute of Technology. Acceleration records recorded after the date of damage show a clear increase in high-frequency short-duration pulses compared to those previously recorded. One undamage pulse and two damage pulses are identified from the data. The occurrence of the detected damage pulses is consistent with a progression of damage and matches the known chronology of damage.

Dinâmica de crescimento de Cedrela odorata L. (Meliaceae) na Floresta Atlântica do Estado do Rio de Janeiro: fenologia, atividade cambial e dendrocronologia

Ao longo do século XX, poucos estudos de dendrocronologia foram desenvolvidos com espécies de ambientes tropicais, em função da crença de que as condições climáticas nessas regiões não apresentavam variações suficientemente marcantes e regulares para induzir um ritmo anual de crescimento radial. A realização de trabalhos sobre esse tema nas últimas décadas revelou que a formação de anéis de crescimento anuais nos trópicos pode estar associada a fatores diversos, como: existência de estação seca bem definida, ocorrência de inundações sazonais, respostas ao comportamento fenológico, respostas ao fotoperíodo e a ritmos endógenos. O presente estudo tem por objetivo compreender a dinâmica de crescimento radial de uma espécie da Mata Atlântica se desenvolvendo em ambiente natural. Para tanto, propôs-se: i) investigar a periodicidade da atividade cambial e dos fatores que a influenciam; ii) estimar a idade e taxa de crescimento diamétrico e iii) correlacionar os fatores ambientais com os anéis de crescimento, em indivíduos de Cedrela odorata L. Para o estudo da atividade cambial, foram obtidas amostras de caule a 1,30 m do solo, contendo periderme, faixa cambial e xilema e floema secundários, por métodos não destrutivos. A fenologia vegetativa e a frutificação dos indivíduos amostrados foram acompanhadas durante todo o período do experimento. O material coletado foi processado segundo técnicas usuais em Anatomia Vegetal e analisado sob microscopia óptica e de fluorescência. Os dados de fotoperíodo, precipitação, temperatura e fenologia vegetativa foram correlacionados à atividade cambial. Para o estudo dos anéis de crescimento, as coletas também foram realizadas a 1,30 m do solo, por meio de sonda de Pressler. As amostras obtidas foram polidas e analisadas sob microscópio estereoscópio, para demarcação e aferição do número de anéis de crescimento, e a largura dos anéis foi mensurada para a determinação das taxas de crescimento radial. A série histórica de temperatura e precipitação foi correlacionada à cronologia dos anéis de crescimento. Os resultados indicaram que a atividade cambial segue um ritmo anual de crescimento, correlacionado à sazonalidade do fotoperíodo, da precipitação e da fenologia vegetativa. A análise dos anéis de crescimento permitiu estimar a idade dos indivíduos e determinar a taxa média de incremento e as taxas de incremento diamétrico acumulado e incremento médio anual para a espécie no sítio de estudo. Os dados de incremento radial evidenciaram a ausência de relação entre a idade e o diâmetro das árvores. A análise da variação na largura dos anéis não apresentou correlações significativas com os fatores climáticos analisados.

A Construção da figura do herói nos mangás e comics: uma análise comparativa entre samurais e super-heróis

Este estudo trata da representação do herói nas histórias em quadrinhos do Japão, os mangás, e dos Estados Unidos, os comics. Esta análise se propõe a comparar a figura do samurai, focada nos títulos Samurai X e Vagabond, e do super-herói, através de Superman e Batman. Para tal, utilizam-se duas minisséries norte-americanas de cada um dos títulos escolhidos publicadas entre o final da década de 1980 e a década de 1990, mesmo período dos quadrinhos japoneses. Os títulos escolhidos ilustram questões-chaves para o entendimento da figura do herói: seu surgimento, morte e confronto com antagonistas. Considerando o vasto material relacionado aos personagens norte-americanos, criados no final da década de 1930, optou-se por trabalhar com sagas específicas ao invés da obra como um todo, o que só foi possível no caso dos mangás. Por isso, essa análise se baseará nas histórias em quadrinhos publicadas a partir do final da década de 1980, preservando assim a paridade cronológica entre comics e mangás, os quais possuem uma cronologia mais rígida se comparada aos primeiros. Quanto aos segmentos escolhidos, no lado do Superman, farão parte dessa análise os arcos Man of Steel, de 1986, com a origem do personagem e A Morte e o Retorno do Superman, de 1992. Já em Batman serão analisadas as HQs Batman: Ano Um, de 1987 e Knightfall, de 1993.

En torno al llamado «arte esquemático-abstracto»: a propósito de unas fechas de Covalanas (Ramales de la Victoria, Cantabria)

[ES] La introducción de técnicas físico-químicas al estudio del grafismo rupestre paleolítico está abriendo nuevos campos de conocimiento sobre los procedimientos técnicos, la cronología y la conservación de los motivos. La utilización de la técnica radiométrica de C14 A.M.S. ha sido aplicada en Covalanas. Las dataciones de época histórica de dos pequeños fragmentos de carbón procedentes de marcas negras sirven para reflexionar en torno al llamado «arte esquemático-abstracto».

Contribución al estudio de las estructuras tumulares en arqueología: entre la similitud morfológica y la disparidad de funciones

[ES] El artículo trata el tema de las estructuras tumulares, su variabilidad formal y funcional (funeraria, lugar de habitación, etc.), así como su distinta cronología. Se describe los casos concretos de Txoritegi (Zerain —Gipuzkoa—) y Galardi (Txoritegi —Gipuzkoa—), unas estructuras tumulares tipo mota utilizadas, posiblemente, a modo de atalaya de vigía en el contexto del período de conflictividad bajomedieval. Es un elemento novedoso en el territorio para cuya interpretación se ha efectuado un análisis de las cuencas visuales mediante SIG.

La cuestión de las azagayas de base hendida magdalenienses en la Cornisa Cantábrica

[ES] Durante la excavación de la cueva de Praile Aitz I (Deba, Gipuzkoa) se ha hallado una azagaya de base hendida sobre un suelo de cantos de caliza en el que se definió un contexto de habitación constituido por un hogar, escasos restos de industria y fauna, y varios colgantes. Estos materiales se atribuyen al Magdaleniense Inferior Cantábrico con fechas que se sitúan entre el 15.190 y 15.810 BP. Aprovechando este descubrimiento se realiza una revisión de ejemplares de similares características hallados en otros yacimientos cantábricos (Balmori, El Castillo) y se plantea la posible cronología magdaleniense del ejemplar de Santimamiñe.

Establecimientos de habitación al aire libre. Los fondos de cabaña de morfología tumular: características, proceso de formación y cronología

[ES] En este artículo se describen una serie de estructuras de tipo tumular, que si aparentemente pudieran recordar a las estructuras funerarias clásicas se alejan de éstas por su morfología, composición, funcionalidad y cronología. Los trabajos de prospección realizados durante los últimos años en la Sierra de Aralar (Gipuzkoa) han permitido localizar medio centenar de estas estructuras tumulares, así como abrir nuevos campos de investigación en torno a la vivienda temporal de los grupos pastoriles en las zonas de montaña.
