Abstract:
The zeolitic imidazolate frameworks (ZIFs) ZIF-8, ZIF-67, and a Zn/Co bimetallic mixture (ZMix) were synthesized and used as fillers in the preparation of composite sulfonated poly(ether ether ketone) (SPEEK) membranes. The presence of the ZIFs in the polymeric matrix enhanced proton transport relative to that observed for SPEEK or ZIFs alone. The real and imaginary parts of the complex conductivity were obtained by electrochemical impedance spectroscopy (EIS), and the temperature and frequency dependence of the real part of the conductivity were analyzed. The results at different temperatures show that the direct current (dc) conductivity was three orders of magnitude higher for composite membranes than for SPEEK, and that of the SPEEK/ZMix membrane was higher than those for SPEEK/Z8 and SPEEK/Z67, respectively. This behavior turns out to be more evident as the temperature increases: the conductivity of the SPEEK/ZMix was 8.5 × 10−3 S·cm−1, while for the SPEEK/Z8 and SPEEK/Z67 membranes, the values were 2.5 × 10−3 S·cm−1 and 1.6 × 10−3 S·cm−1, respectively, at 120 °C. Similarly, the real and imaginary parts of the complex dielectric constant were obtained, and an analysis of tan δ was carried out for all of the membranes under study. Using this value, the diffusion coefficient and the charge carrier density were obtained using the analysis of electrode polarization (EP).

Abstract:
We report the first successful regeneration of haploid lines in persian walnut (Juglans regia) developed by in situ parthenogenesis followed by embryo rescue. Female flowers of cultivars Hartley and Pedro and two native Iranian selections (Z63 and Z67) were pollinated using pollen of selections Z53 and Z30 that had been irradiated with gamma rays at five doses (50, 150, 300, 600, and 900 Gy). Gamma-irradiated pollen induced fruit set and development of some parthenogenetic embryos. The immature embryos were excised 30 and 45 days after pollination, cultured in vitro, and then stratified for 30 days at 4 °C to overcome dormancy. Ploidy level of the resulting plantlets was determined by chromosome counting and flow cytometry. Haploid plants were obtained from ‘Hartley’, ‘Pedro’, Z63, and Z67 after pollination using pollen irradiated at 300 and 600 Gy. Plants obtained from pollen irradiated at 50 and 150 Gy were all diploid. Molecular marker analysis using four simple sequence repeat (SSR) markers also showed that all the diploid plants recovered were zygotic and no spontaneous double haploid plants were obtained in this work. Also, the haploid plantlets presented only one allele of their female parents. These profiles confirmed the parthenogenetic origin of the obtained haploid plants. The techniques used to induce haploid walnut plants by irradiated pollen were successful and could be used in breeding programs and accelerate genome analysis in this plant in which the genome size is approximately three times the size of the human genome.

Abstract:
The objective of this work was to determine the chilling and heat requirements of Persian walnut cultivars and genotypes using excised twigs. The experiment was carried out from Nov. 2006 and 2007 to Mar. 2007 and 2008. One-year-old twigs were prepared from four cultivars and four domestic genotypes of Juglans regia L. After leaf fall, the twigs were taken and placed in plastic bags and kept at 4 ± 1 °C to stimulate 400 to 1500 chilling hours. After chilling, the excised twigs were transferred to the greenhouse with a natural photoperiod and a temperature from 18 to 27 °C. The evaluation of budbreak was made three times a week and the number of accumulated growing degree hours (°C) was determined until the buds reached the balloon or green tip stage. The chilling requirements were lowest (400 h) for catkins and highest (1000 h) for lateral buds. The Serr cultivar and ‘Z30’ genotype had the lowest chilling requirements (650 and 650 h). ‘Lara’, ‘Z63’, ‘Z53’, ‘Pedro’, and ‘Z67’ showed intermediate chilling requirements with values of 900, 900, 800, 750, and 750 h, respectively. Finally, ‘Hartley’ completed its dormancy after an accumulation of 1000 h, being the walnut cultivar with the highest chilling requirement in our study. As the final result, the cultivars and genotypes were classified into three groups based on their heat requirements: low requirement (‘Z30’ and ‘Serr’), medium requirement (‘Z53’, ‘Z67’, ‘Lara’, and ‘Pedro’), and high requirement (‘Hartley’ and ‘Z63’).

Abstract:
O objetivo deste trabalho foi avaliar o efeito do recobrimento de sementes de milho com ácidos húmicos (AH), bactérias diazotróficas endofíticas e o uso em conjunto de AH e bactérias diazotróficas endofíticas, na estimulação do crescimento vegetal e na população de bactérias estabelecidas na planta hospedeira. A adição de AH, bactérias e o uso em conjunto estimularam o crescimento vegetal. Os AH utilizados no recobrimento de sementes de milho têm menor capacidade de estimular o crescimento radicular, em comparação ao uso em solução. O recobrimento de sementes é uma opção de inoculação de bactérias diazotróficas endofíticas da espécie Herbaspirillum seropedicae (Z67).

Abstract:
Bacteria from the genus Herbaspirillum are endophytes responsible for nitrogen fixation in gramineous plants of economic importance such as maize, sugarcane, sorghum, rice, and wheat. Some species are known to produce plant growth substances. In contrast, Herbaspirillum rubrisubalbicans strains are known to be mild plant pathogens. The molecular communication between the plant and the microbes might involve lipopolysaccharides present in the outer membrane of these gram-negative bacteria. Phenol–water extraction was used to obtain lipopolysaccharides from 7 strains of Herbaspirillum seropedicae (SmR1, Z67, Z78, ZA95, and M2) and H. rubrisubalbicans (M1 and M4). The electrophoretic profiles and chemical composition of the lipopolysaccharides obtained in the phenol and aqueous extracts were shown herein.

Abstract:
A β-glucoronidase (GUS)-marked strain of Herbaspirillum seropedicae Z67 was inoculated onto rice seedling cvs. IR42 and IR72. Internal populations peaked at over 106 log CFU per gram of fresh weight by 5 to 7 days after inoculation (DAI) but declined to 103 to 104 log CFU per gram of fresh weight by 28 DAI. GUS staining was most intense on coleoptiles, lateral roots, and at the junctions of some of the main and lateral roots. Bacteria entered the roots via cracks at the points of lateral root emergence, with cv. IR72 appearing to be more aggressively infected than cv. IR42. H. seropedicae subsequently colonized the root intercellular spaces, aerenchyma, and cortical cells, with a few penetrating the stele to enter the vascular tissue. Xylem vessels in leaves and stems were extensively colonized at 2 DAI but, in later harvests (7 and 13 DAI), a host defense reaction was often observed. Dense colonies of H. seropedicae with some bacteria expressing nitrogenase Fe-protein were seen within leaf and stem epidermal cells, intercellular spaces, and substomatal cavities up until 28 DAI. Epiphytic bacteria were also seen. Both varieties showed nitrogenase activity but only with added C, and the dry weights of the inoculated plants were significantly increased. Only cv. IR42 showed a significant (approximately 30%) increase in N content above that of the uninoculated controls, and it also incorporated a significant amount of 15N2.

Abstract:
Os ácidos húmicos podem atuar no aumento da população de bactérias diazotróficas introduzidas no interior da planta e, consequentemente, no incremento dos efeitos benéficos sobre a planta hospedeira. Com este trabalho, objetivou-se avaliar o efeito dos ácidos húmicos na inoculação de bactérias diazotróficas endofíticas, em sementes de milho. Foi utilizada a estirpe Herbaspirillum seropedicae Z67 BR 11175. A inoculação das sementes com as bactérias e a adição de ácidos húmicos foram realizadas pelo recobrimento das sementes de milho UENF 506-8, com a mistura de calcário, meio de cultura semisólido, água e cimentante. As sementes recobertas foram semeadas em vasos Leonard. Aos 40 dias após a semeadura, as plântulas foram coletadas, e foi realizada a contagem de bactérias nas raízes pela técnica do Número Mais Provável. Os resultados deste trabalho mostram que os ácidos húmicos não interferem negativamente no crescimento das bactérias e estimulam a colonização da microbiota nativa. No entanto, nas condições avaliadas, a aplicação conjunta de bactérias + ácidos húmicos não estimulou o crescimento da população de bactérias inoculadas nas plântulas de milho.

Abstract:
Conduziu-se este trabalho com o objetivo de avaliar a qualidade fisiológica das sementes recobertas com diferentes misturas e armazenadas, assim como a sobrevivência das células bacterianas no recobrimento destas. Utilizou-se neste estudo a estirpe H. seropedicae Z67 BR 11175. O recobrimento das sementes de milho 'UENF 506-8' foi realizado com a mistura de calcário, meio de cultura semi-sólido, água e cimentante. As sementes foram acondicionadas durante três meses, em sacos de papel multifoliado e armazenadas em duas condições: ambiente de laboratório (temperatura média de 26,2 ºC e UR média de 61,5%) e câmara BOD. A cada 30 dias de armazenamento, foram efetuadas determinações do teor de água, contagem de bactérias e avaliações da qualidade fisiológica das sementes. O recobrimento das sementes não altera a perda natural da qualidade fisiológica das sementes durante o armazenamento. Dentre as condições de armazenamento estudadas, a mais adequada para a manutenção das sementes foi a temperatura média de 26,4 ºC e UR média de 61,5 %. As células bacterianas foram observadas nas raízes das plântulas oriundas de sementes revestidas com bactéria, armazenadas por até 60 dias independente da condição de armazenamento.

Abstract:
Abstract The original title for Henry Purcell’s first semi-opera, written in 1690, was The Prophetess: or, The History of Dioclesian (Z627), It was adapted ‘after the manner of an opera’ from the Fletcher and Massinger play The Prophetess of 1622 by Thomas Betterton, actor-manager of Dorset Garden Theatre, and a full score was printed by Heptinstall the following year. After Gottfried Finger’s The Virgin Prophetess appeared in 1701, the Purcell opera was often referred to as Dioclesian, which title has also been used by the Purcell Society. A full discussion of its provenance can be found in Henry Purcell’s First SemiOpera Dioclesian which was written with the intention of contributing to a scrupulous production of this neglected work. However, it soon became clear that to stage an early opera properly, far more research would have to be done on the non-musical and non-verbal aspects of the work, including the theatre architecture, stage design, costume, gesture, choreography, and their contemporaneous connotations. Technical research into the construction of Dorset Garden Theatre, where the semi-operas were first staged, has led to new insights, and contemporary illustrations have contributed to a reconstruction of the original stage picture.
