Contemporary engagements within corridors of the past: temporal elasticity, graffiti, and the materiality of St. Rock Street, Barcelona

In a medieval Barcelonan side-street, urine, rubbish, and a bewildering array of graphic imagery splatters the narrowing walls between two major thoroughfares. A contemporary conflict between residents, unknown artists and others is played out using banners, bottles, stickers, posters, stencils, spray paint, and bodily substances. In this shadowed liminality, local and global debates are superimposed upon substructures constructed from disease, prostitution, and the Saint of the Plague. The continuing urban struggle constitutes temporal statements of dirt and purity, violence and humour, dominance and resistance, death and salvation. Like the renovated facades masking the crumbling remains of structures long neglected, the government’s literal whitewashing of the art is a temporal cover-up of a discursive symptom stretching from deeply embedded preconditions. However, from his niche in the angular bend of the alley bearing his name, the statue of St. Rock remains unblinkingly staring, raised above the contestations expressed below.

Irrigation performance and gross water productivity in furrow-irrigated ornamental tree production

In the ornamental plant production region of Girona (Spain), which is one of the largest of its kind in southern Europe, most of the surface is irrigated using wide blocked-end furrows. The objectives of this paper were: (1) to evaluate the irrigation scheduling methods used by ornamental plant producers; (2) to analyse different scenarios in order to assess how they affect irrigation performance; (3) to evaluate the risk of deep percolation; and (4) to calculate gross water productivity. A two-year study in a representative commercial field, planted with Prunus cerasifera ‘Nigra’, was carried out. The irrigation dose applied by the farmers was slightly smaller than the required water dose estimated by the use of two different methods: the first based on soil water content, and the second based on evapotranspiration. Distribution uniformity and application eff iciency were high, with mean values above 87%. Soil water content measurements revealed that even at the end of the furrow, where the infiltrated water depth was greatest, more than 90% of the infiltrated water was retained in the shallowest 40 cm of the soil; accordingly, the risk of water loss due to deep percolation was minimal. Gross water productivity for ornamental tree production was € 11.70 m–3, approximately 20 times higher than that obtained with maize in the same region.

Caracterização morfológica de seis variedades cítricas com potencial ornamental

Embora o Brasil seja o maior produtor mundial de citros, a produção de mudas cítricas para fins ornamentais é pequena, e a pesquisa nessa área ainda é escassa. Os citros são atrativos para o paisagismo principalmente por seus frutos, que são de tamanhos, formatos e cores variados e que, em sua maioria, podem ser ingeridos in natura. O objetivo deste trabalho foi caracterizar, para fins paisagísticos, seis variedades cítricas com potencial ornamental: cidra Mão-de-Buda, kunquat Nagami, laranja Cipó, laranja Imperial, limão Faustrine e tangerina Venezuela, cultivadas no Banco Ativo de Germoplasma do Centro APTA Citros Sylvio Moreira, do Instituto Agronômico, em Cordeirópolis-SP. Para cada variedade, foram coletados 30 folhas adultas, 30 flores totalmente abertas e 30 frutos maduros para análise de seus caracteres morfológicos. As características das árvores também foram avaliadas. O delineamento utilizado foi o inteiramente casualizado, e a média das 30 medidas de cada variável representou a variedade. Foram observadas diferenças morfológicas acentuadas entre as seis variedades e todas apresentaram potencial ornamental.

Japanin musiikkimarkkinat : Japanin pop- ja rock-markkinoiden erityispiirteet suomalaisen musiikin näkökulmasta

Tämän opinnäytetyön tavoite on selvittää suomalaisen pop- ja rock-musiikin vientimahdollisuuksia yhteen maailman kiinnostavimpaan ja ostovoimaisimpaan maahan, Japaniin, ja tuoda esille sen luonnetta suhteessa suomalaiseen musiikkiin. Opinnäytetyön teoriaosa selvittää Suomen tämän hetkistä musiikkiviennin tilannetta ja syitä siihen, miksi Japanin markkinat on erittäin kiinnostava alue viennin saralla. Kirjallinen viitekehys työlle muodostuu pääasiassa kootuista musiikkialan raporteista, tilastoista ja artikkeleista. Empiirisessä osassa keskeistä tutkimusmateriaalia ovat Tokion Suomen Instituutissa kolmen kuukauden työharjoittelun yhteydessä kertyneet kokemukset ja asiantuntijahaastatteluaineisto. Nämä avaavat Japanin musiikkimarkkinoita luoden parempaa kuvaa siellä vallitsevista kilpailuolosuhteista, maan tavoista ja kiinnostuksen kohteista, sekä japanilaisten mielikuvaa suomalaisesta musiikista. Suomessa musiikkimarkkinat ovat hyvin pienet, mutta niiden laajentamiseen viennillä on alettu keskittyä yhä enenevissä määrin. Koska Japanissa on maailman toiseksi suurimmat musiikkimarkkinat, se on erittäin varteenotettava kohde myös suomalaisen musiikin viennille. Vaikka suomalainen musiikki on toistaiseksi suhteellisen tuntematonta suurelle osalle japanilaisista, suhtaudutaan siihen positiivisesti. Japanilaisten mielestä Suomesta tuleva musiikki on verrattuna moniin muihin maihin paljon omaleimaisempaa ja tämä tekee siitä kiinnostavan. Viennissä ongelmia kuitenkin luovat kielimuuri ja japanilaisten kulttuurisidonnaiset toimintatavat. Ilman hyviä suhteita toiminta Japanin musiikkialan kentällä on lähes mahdotonta. Keskeistä on huomioida paikalliset toimintatavat ja toimia kiireettä kaukonäköisesti. Tuotteen kaikkien osa-alueiden tulisi olla suunniteltu Japanin markkinoihin soveltuviksi jo tarjontavaiheessa. Parantaakseen suomalaisen musiikin vientiä Japaniin on tärkeää tuotteiden menestyksien yhteydessä tuoda esille niiden suomalaisuutta ja näin lisätä kiinnostusta japanilaisten silmissä. Lähtökohtaisesti suomalaisella musiikilla on kuitenkin hyvät mahdollisuudet menestykseen Japanin musiikkimarkkinoilla. Suurimpina ongelmina voidaan pitää vähäistä tietoa japanilaisten mielenkiinnon kohteista, toimintatapojen kulttuurisia eroja ja suomalaisten vientiin panostettavien varojen vähyyttä.

Gens,humans i rock

El rock'n'roll, un dels estils musicals més influents del segle XX, es va gestar als EUA durant la dècada de 1940 a partir del blues, el rhythm'n'blues i el country. Joel vaig descobrir de forma conscient el 1979, quan tenia 14 anys. I el seu ritme em va captivar tant les neurones que continua sent el meu estil musical predilecte, amb el qual identifico bona part de les meves emocions.

Abutilon ornamental (Abutilon sp. - Malvaceae) mostrando pústulas de Synchytrium australe

Plantas de abutilon recebidas para análise fitopatológica pelo Instituto Biológico, São Paulo, Brasil mostrando como sintomas pústulas semelhantes a ferrugem (Uredinales) sobre folhas e caule foram estudadas para determinar o agente causal. Numerosos esporângios amarelos característicos de fungos zoospóricos pertencentes à Ordem Chytridiales foram encontrados no interior de galhas superficiais. Com base no estudo de KARLING (1955), o patógeno foi identificado como Synchytrium australe Speg. O material foi herborizado e armazenado no Herbário Micológico do Instituto Biológico sob o número IBI/SP 11975. Esta foi a primeira constatação desta espécie no Brasil.

Powdery mildew of ornamental species caused by Oidiopsis haplophylli in Brazil

Oidiopsis haplophylli (syn. Oidiopsis sicula) was identified as the causal agent of powdery mildew diseases occurring on five ornamental species in Brazil. This disease was observed in plastic house-grown lisianthus (Eustoma grandiflorum: Gentianaceae), in nasturtium (Tropaeolum majus: Tropaeolaceae) cultivated under open field conditions and in greenhouse-grown calla lily (Zantedeschia aethiopica: Araceae), impatiens (Impatiens balsamina: Balsaminaceae) and balloon plant (Asclepias physocarpa: Asclepiadaceae). Typical disease symptoms consisted of chlorotic areas on the upper leaf surface corresponding to a fungal colony in the abaxial surface. With the disease progression, these chlorotic areas eventually turned to necrotic (brown) lesions. Fungi morphology on all hosts was similar to that described for the imperfect stage of Leveillula taurica (O. haplophylli). The Koch's postulates were fulfilled by inoculating symptom-free plants via leaf-to-leaf contact with fungal colonies. Additional inoculations using an isolate of O. haplophylli from sweet pepper (Capsicum annuum) demonstrated that it is pathogenic to all five species belonging to distinct botanical families, indicating lack of host specialization. This is the first formal report of a powdery mildew disease on lisianthus, calla lilly, impatiens and nasturtium in Brazil. It is, to our knowledge, the first report of O. haplophyllii infecting A. physocarpa, extending the host range of this atypical powdery mildew-inducing fungus. This disease might become important on these ornamental crops especially in protected cultivation and also under field conditions in hot and dry areas of Brazil.

Vegetative propagation of bauhinia x blakeana, an ornamental sterile tree

Bauhinia x blakeana (B. purpurea x B. variegata) is a natural hybrid that has been cultivated in gardens, streets and parks. Due to its sterility, it must be vegetatively propagated. The objective of this work was to evaluate the viability of cuttings and grafting on its propagation. Semi-woody cuttings were collected during four seasons and treated with 0; 1,000; 2,000; and 3,000 mg L-1 of IBA. The experimental design was entirely randomized and the treatments were arranged in a 4x4 factorial scheme (four collecting times x four IBA concentrations) and five replications with 10 cuttings each, per collecting time and per IBA concentration. Characteristics of roots and shoots were evaluated after 90 days. The data means were compared by the Tukey test and submitted to the polynomial regression analysis. For the grafting experiment, B. variegata and B. variegata var. candida plants of six and 12 months were used as rootstocks and the splice graft and T-budding methods were tested. The experimental design was entirely randomized and the treatments were arranged in a 2x2x2 factorial scheme (two rootstock species x two grafting methods x two rootstock ages) and four replications with five plants each, per rootstock species, per grafting method and per rootstock age. Characteristics of shoots were evaluated after 90 days and the data means were compared by the Tukey test. B. x blakeana can be propagated by semi-woody cuttings collected in spring, without IBA application, or in summer, with the application of 3,000 mg L-1 of IBA. The tested grafting methods were not effective.
