A espécie Prochilodus lineatus é de grande importância comercial na região dos rios Grande, Pardo e Mogi-Guaçu e tem como característica a formação de grandes cardumes, apta a desenvolver amplos deslocamentos migratórios. O presente trabalho objetivou avaliar, por meio das características morfométricas e etária, se os curimbatás (P. lineatus) dos diferentes estoques migradores e residentes constituem uma única população, havendo interação entre as sub-populações no período de piracema (migração reprodutiva). Utilizou-se um delineamento inteiramente casualizado em esquema fatorial 4 x 2, com quatro tipos de estoques (um residente e três migradores) e dois sexos (macho e fêmea) com trinta repetições, considerando cada peixe como unidade experimental. Foi observada variação de 80,19% para o primeiro componente principal e 8,09% do segundo componente principal fornecida pelas dez variáveis morfométricas dos estoques residentes e migradores. O estoque residente correspondeu aos maiores valores para todas as variáveis morfométricas. Houve sobreposição dos escores individuais das mesmas características entre os estoques migradores. Observou-se predominância de machos entre os estoques residentes e migrador I e II. As semelhanças morfométricas verificadas entre os estoques migradores indicam tratar-se de uma única população, com pequenas variações interpopulacional.

Introducción Ya en la primera fase del movimiento independentista hispanoamericano varios ciudadanos paraguayos formaron en Asunción, en mayo de 1811, un gobierno propio que declaró su desvinculación del virreinato del Rio de la Plata. En Octubre de 1813 la provincia se separó de España, y manteniendo su viejo nombre indígena de Paraguay, proclamó la República.

El cerro Chopo (también llamado Anunciación, Coronación, Asunción), consiste en un cono de piroclastos de tamaños variados: cenizas finas, lapilli y bombas tipo “corteza de pan”, además de un conjunto de relictos de pequeñas coladas de lava de composición pleistocenica o más joven. En sus alrededores afloran lavas que. Dadas su morfología, composición y algunas pequeñas evidencias estructurales, hacen especulativo su origen, así como el del cono, del tipo fisural. A estas lavas se les denomina como Formación Las Pulgas; intercaladas con ellas se encuentran tobas que, junto con las ignimbritas que afloran extensamente en toda la región, vienen a ser el complemento de los procesos eruptivos regionales.

Historic house museums form a significant component of the built heritage and social history of a country. They vary from the elaborate mansions of the wealthy to modest dwellings of the working class. Regardless of the original owner's status in society these house museums are vital to an understanding of architecture, culture and society from a bygone era. The Newstead House, the oldest surviving residence, in Brisbane, is the first house to be designated a 'Historic House Museum' in Queensland. It is a representative example of a house that demonstrates the British colonial heritage of 19th century Australia. Originally a modest cottage, on 34 acres of land, the Newstead house was built by a Scottish migrant. The ownership of the house and land changed many times, during the period from 1847 to 1939. During this period a series of prominent residents of Brisbane either owned or rented this residence. They included, an officer of the Royal Navy, politicians, magistrates, merchant ship owners, and a Consul General of the United States of America. As a result, the house went through a series of renovations and extensions to accommodate the needs of its owners and their position in society. This paper aims to investigate the significance of historic museum houses in educating the community on aspects of social history, culture and architecture of 19th century Australia. It will focus on the heritage listed Newstead House as a case study to demonstrate the significance of the house as an artefact and an educational tool.

In vitro studies indicate that folate in collected human blood is vulnerable to degradation after exposure to ultraviolet (UV) radiation. This has raised concerns about folate depletion in individuals with high sun exposure. Here, we investigate the association between personal solar UV radiation exposure and serum folate concentration, using a three-week prospective study that was undertaken in females aged 18–47 years in Brisbane, Australia (153 E, 27 S). Following two weeks of supplementation with 500 μg of folic acid daily, the change in serum folate status was assessed over a 7-day period of measured personal sun exposure. Compared to participants with personal UV exposures of <200 Joules per day, participants with personal UV exposures of 200–599 and >600 Joules per day had significantly higher depletion of serum folate (p = 0.015). Multivariable analysis revealed personal UV exposure as the strongest predictor accounting for 20% of the overall change in serum folate (Standardised B = −0.49; t = −3.75; p = <0.01). These data show that increasing solar UV radiation exposures reduces the effectiveness of folic acid supplementation. The consequences of this association may be most pronounced for vulnerable individuals, such as women who are pregnant or of childbearing age with high sun exposures.

Background Aquatic exercise has been widely used for rehabilitation and functional recovery due to its physical and physiological benefits. However, there is a high variability in reporting on the muscle activity from surface electromyographic (sEMG) signals. The aim of this study is to present an updated review of the literature on the state of the art of muscle activity recorded using sEMG during activities and exercise performed by humans in water. Methods A literature search was performed to identify studies of aquatic exercise movement. Results Twenty-one studies were selected for critical appraisal. Sample size, functional tasks analyzed, and muscles recorded were studied for each paper. The clinical contribution of the paper was evaluated. Conclusions Muscle activity tends to be lower in water-based compared to land-based activity; however more research is needed to understand why. Approaches from basic and applied sciences could support the understanding of relevant aspects for clinical practice.

Background The aim of this study was to compare through surface electromyographic (sEMG) recordings of the maximum voluntary contraction (MVC) on dry land and in water by manual muscle test (MMT). Method Sixteen healthy right-handed subjects (8 males and 8 females) participated in measurement of muscle activation of the right shoulder. The selected muscles were the cervical erector spinae, trapezius, pectoralis, anterior deltoid, middle deltoid, infraspinatus and latissimus dorsi. The MVC test conditions were random with respect to the order on the land/in water. Results For each muscle, the MVC test was performed and measured through sEMG to determine differences in muscle activation in both conditions. For all muscles except the latissimus dorsi, no significant differences were observed between land and water MVC scores (p = 0.063–0.679) and precision (%Diff = 7–10%) were observed between MVC conditions in the muscles trapezius, anterior deltoid and middle deltoid. Conclusions If the procedure for data collection is optimal, under MMT conditions it appears that comparable MVC sEMG values were achieved on land and in water and the integrity of the EMG recordings were maintained during wáter immersion.

Treasures of a Patriot Eliel Aspelin-Haapkylä as an art collector and art historian Treasures of a Patriot is a study of Eliel Aspelin-Haapkylä (1847 - 1917), professor of aesthetics and modern literature, as an art collector and art historian. The study combines the biographical perspective, art history as a discipline in the 19th-century Finland, and Aspelin-Haapkylä s art historical scholarship. My intention was to answer to questions such as what kind of an art collector an academic art historian was, why he collected art and cultural-historical objects and what the purpose of his collecting was. Aspelin-Haapkylä was an ideal choice for the main character because the ideologies of the era, culture, art and European ideas, especially German ideas about museums, are intertwined in his life. In addition, the ideas of the Fennomen can be found in his ideological background. Together with his wife, Ida Aspelin-Haapkylä, he bequeathed a rich donation to the National Museum of Finland, and a wideranging archive concerning the collection, his writings, and letters to the Finnish Literature Society. I have highlighted the materials from the archives related both to the collection and art history, especially the letters between Aspelin-Haapkylä and artists, fellow members of academia, his spouse and relatives. The content and the structure of the research are divided into seven main chapters. First, I discuss Susan M. Pearce s theory of collecting and the history of collecting. I also introduce some other art historians who were private collectors. The late 19th-century Fennomen and other nationalists who were active in cultural life and the arts, are introduced in the second chapter. In the third I deal with Aspelin-Haapkylä s collection of European art combined with his writings, his early published works, studies and many trips to Europe. The fourth and the fifth chapters are dedicated to those Finnish artists who he wrote biographies of, and the artists of his own era whom he supported. The sixth chapter discusses institutions and channels of influence and power through which the initiative to found the National Museum of Finland, his action in the Antell Delegation and co-operation with the art merchant Henryk Bukowski, rise up to the fore. Finally, I process the last will and the fate of the collection from 1917 until 1932. As an appendix, I have included a report and reconstruction of the art collection. The catalogue is based on the words in Aspelin-Haapkylä s the so-called blue notebooks, which I have completed with additions from other sources.
