The present study, is characterized as qualitative investigative, has as main objective to analyze the convergence between the fields of the visual arts and design. To base the analysis, it was developed a bibliographical research that raised the concept of hybrid language, the mixing of different races in Brazilian design, the relations between art and design and the Design Prize Museum of Brazilian House (MCB). As shown on the basis of this theoretical survey, it was presented the designers Luciana Martins and Gerson de Oliveira, from the company, OVO, and the objects selected for this study, that are the two products awarded from the MCB, which contain artistic characteristics and are commercialized and recognized as objects of Brazilian design. These products were analyzed and the hybrid characteristics of them were raised.

Nelson Mandela has been an example of fighting and going over the adversities since his prison in 1962 until his election to be the president of South Africa in 1994. His effort against the apartheid in South Africa might be compared to a classical hero according to the anthropological view of Eliade (1972), Campbell (1991; 2007) and Propp’s structuralist perspective (1984). His journey toward heroism and his strategies to get the adhesion of the white minority (Afrikaners) to his purposes of joining the races in South Africa will be analyzed in this article with the theoretical support of the Greimasian semiotics, Propp’s studies (1984) and anthropology. The movie Invictus will be the object of analysis as it shows the moment of Mandela’s social-political fight as the president, with the support of the local rugby team in order to have the racial integration in the country and the political support of the white minority.

O objetivo deste trabalho foi relacionar a intensidade do exercício físico e as concentrações de cortisol plasmático em cavalos de enduro, uma competição em que somente animais experientes podem competir nas provas mais longas. Foram utilizados 30 equinos Puro Sangue Árabe e mestiços Árabe, machos ou fêmeas participantes de provas de enduro. Foram divididos em três grupos de 10 animais: (G1): percorreram mais de 100km, (G2): percorreram menos de 100km, e (G3): desqualificados por causa metabólica. Foram realizadas dosagens de cortisol plasmático em três momentos diferentes: (t0): dia anterior à competição, (t1): 30 a 60 minutos após o término da prova e, (t2): 90 a 120 minutos após o término da prova. Concluiu-se que o enduro leva ao aumento do cortisol plasmático; animais que percorrem maiores distâncias apresentam menor aumento das concentrações de cortisol; animais desqualificados por causa metabólica, que passam por situações de extremo esforço físico, tendem a valores de cortisol mais elevados e animais menos experientes apresentam valores de cortisol mais elevados mesmo tendo percorrido menores distâncias.

[POR] Descoberto entre 1460 e 1462, o Arquipélago de Cabo Verde, situado no Oceano Atlântico, constituiu ao longo de vários séculos, escala obrigatória dos navios que faziam as ligações atlânticas entre os portos das Américas, da Europa e da África Graças a sua situação privilegiada, o espaço cabo-verdiano não foi um mero ponto de reabastecimento, mas também um importante ponto de cruzamento de culturas e de raças. Pretende-se, neste texto, abordar o papel que Cabo Verde teve no Atlântico incidindo, particularmente, na dimensão cultural resultante do contacto entre povos e culturas provenientes de diferentes paragens que se fixaram no arquipélago ou que por aqui passaram. Procurar-se-á evidenciar não só a importância que Cabo Verde teve enquanto ponto de passagem obrigatória mas, sobretudo, as contribuições que mais marcadamente se denunciaram, isto é, os apports culturais que mais se acentuaram em Cabo Verde, como processos recebidos dos estrangeiros que por estas ilhas se cruzaram.

Eduardo Zamacois (Pinar del Río, 1873- Buenos Aires, 1971) was a main actor of the spanish’s literature and edition movement from the first third of the 20th century. He was the founder of magazines that had a big impact like “Germinal”, introductive of the sicalipsis (“La Vida Galante”) or so innovative that deserved an special chapter in the history of literature (“El Cuento Semanal” e “Los Contemporáneos”). With this work, it is intended to recreate the most significant stages from his autobiography adventure including the new information that offers his non before published letters exchange with his last sentimental partner. As a writer, his work was very popular in his homeland, translated to the world and reissued in Ibero-America. His literature work is based in three different phases. He began with the use of gallant literature (with books like La enferma, Punto negro) and took an adventure with the pays of mystery and irony (El otro, El misterio de un hombre pequñito, La opinion ajena) to finally focused in a narrative style of a realistic kind, that includes social critique (Las raíces). His last published novel in Spain is a portrait of Madrid during its long siege by the nationalist troops (El asedio de Madrid), a profound tribute to the people’s heroism and a declaration of love to the capital, that was his place of residence for a long time. While his exile, that took him to Cuba, New York and Buenos Aires, he worked in the radio, the dubbing industry and in finishing his most detailed bibliography, Un hombre que se va, a valuable document of that time.

Tephritis conura parasitiert verschiedene Kratzdistel-Arten (Cirsium sp.), darunter Cirsium heterophyllum und C. oleraceum. Vorhergehende Studien hatten gezeigt, dass T. conura auf diesen Wirten zumindest partiell reproduktiv isolierte Wirtsrassen ausgebildet hat. Ziel der vorliegenden Arbeit war es durch die Kombination von genetischen und morphometrischen Analysen mit direkten Untersuchungen von potentiellen Isolationsbarrieren einerseits, und die Einbeziehung verschiedener Verbreitungsmuster der Wirtspflanzen andererseits, die Artbildungsprozesse bei T. conura besser zu verstehen. Der Genfluss zwischen Heterophyllum- und Oleraceum-Fliegen wird durch eine Reihe von Isolationsbarrieren eingeschränkt: Habitatspräferenzen und Unterschiede im Zeitpunkt der sexuellen Aktivität wirken als präzygotische Barrieren, mangelnde Adaptation der Larven an den Alternativwirt sowie möglicherweise genomische Inkompatibilitäten bei Hybriden stellen postzygotische Barrieren dar. Das Maß der genetischen Differenzierung (Allozyme und mtDNA) lässt den Schluss zu, dass diese Barrieren in einer nahezu kompletten reproduktiven Isolation resultieren, so dass Heterophyllum- und Oleraceum-Fliegen eher als eigene Arten denn als Wirtsrassen angesehen werden können. Die mtDNA-Daten deuten darauf hin, dass C. heterophyllum der ursprüngliche Wirt gewesen ist und dass der Wirtswechsel im Laufe der letzten Eiszeit stattgefunden hat. Dabei scheint ein peripatrisches Szenario am wahrscheinlichsten, bei dem die relative Häufigkeit der Wirte für den Differenzierungsprozess die entscheidende Rolle spielte.

In wheat, stem rust is known to rapidly evolve new virulence to resistance genes. While more than 50 stem rust resistance (Sr) loci have been identified in wheat, only a few remain effective, particularly against the highly virulent race Ug99 (TTKSK race) and a mixture of durum-specific races. An association mapping (AM) study based on 183 durum wheat accessions was utilized to identify resistance loci for stem rust response in Ethiopia over four seasons and artificial inoculation with Ug99 (TTKSK race) and a mixture of durum-specific races under field conditions as well as in greenhouse test at seedling stage under controlled conditions for resistance to four highly virulent stem rust races: TRTTF, TTTTF, (TTKSK (Ug99) and JRCQC. The panel was profiled with 1,253 SSR and DArT markers. Twelve QTL-tagging markers were significant (P < 0.05) across three to four seasons. The role of Sr13, Sr9, Sr14, Sr17, and Sr28 was confirmed. Thirteen significant markers were in regions with no Sr genes/QTLs. The results under controlled conditions showed that 15, 20, 19 and 19 chromosome regions harbored markers that showed significant effects for races TRTTF, TTTTF, TTKSK and JRCQC, respectively. These genomic regions showed marker R2 values ranging from 1.13 to 8.34, 1.92 to 17.64, 1.75 to 23.12 and 1.51 to 15.33% for races TRTTF, TTTTF, TTKSK and JRCQC, respectively. The study demonstrates that stem rust resistance in durum wheat is governed in part by shared loci and in part by race-specific ones. The QTLs identified in this study through AM will be useful in the marker-assisted development of durum wheat cultivars with durable stem rust resistance.

The aim of this study was to examine whether a real high speed-short term competition influences clinicopathological data focusing on muscle enzymes, iron profile and Acute Phase Proteins. 30 Thoroughbred racing horses (15 geldings and 15 females) aged between 4-12 years (mean 7 years), were used for the study. All the animals performed a high speed-short term competition for a total distance of 154 m in about 12 seconds, repeated 8 times, within approximately one hour (Niballo Horse Race). Blood samples were obtained 24 hours before and within 30 minutes after the end of the races. On all samples were performed a complete blood count (CBC), biochemical and haemostatic profiles. The post-race concentrations for the single parameter were corrected using an estimation of the plasma volume contraction according to the individual Alb concentration. Data were analysed with descriptive statistics and the percentage of variation from the baseline values were recorded. Pre- and post-race results were compared with non-parametric statistics (Mann Whitney U test). A difference was considered significant at p<0.05. A significant plasma volume contraction after the race was detected (Hct, Alb; p<0.01). Other relevant findings were increased concentrations of muscular enzymes (CK, LDH; p<0.01), Crt (p<0.01), significant increased uric acid (p<0.01), a significant decrease of haptoglobin (p<0.01) associated to an increase of ferritin concentrations (p<0.01), significant decrease of fibrinogen (p<0.05) accompanied by a non-significant increase of D-Dimers concentrations (p=0.08). This competition produced relevant abnormalities on clinical pathology in galloping horses. This study confirms a significant muscular damage, oxidative stress, intravascular haemolysis and subclinical hemostatic alterations. Further studies are needed to better understand the pathogenesis, the medical relevance and the impact on performance of these alterations in equine sport medicine.
