J.C. Bach's London keyboard sonatas : style and context
No full textJ. C. Bach's keyboard works include several sets of accompanied sonatas, a genre that enjoyed a wide popularity during the Classical era, but never
found its way into the concert repertoire. The accompanied sonata was a genre meant for domestic performance; the solo keyboard sonata, on
the other hand, was adopted in due course by concert audiences. J. C. Bach composed works within both genres during most of his productive years, and his output constitutes a corpus of remarkable consistency. J. C. Bach's removal to London in 1762 coincided with his clear adoption of a galant style, marked by the Italianate influence, and the abandonment of most Baroque traits. The British milieu provided additional factors: the rise of the pianoforte, a thriving music-publishing market, and a great interest in domestic music making among the affluent classes. These factors marked J. C. Bach's output at various levels. Keyboard works had to conform to the proficiency of the amateur performer, a
fact reflected in the accompanied output mostly. The number of movements, their length, and the inclusion of particular technical devices are readily observable differences between the two genres. The most remarkable
distinction lies perhaps in the preference for binary sonata format in the accompanied. sonatas from the mid 1760s to the 1770s, in spite of a later tendency for tripartite designs in both genres. J. C. Bach's lifelong preference for motivic phrase structure conditioned his keyboard production and partly explains the gap in quality between some of his works and sonatas composed around the same time by Haydn and Mozart, who developed more effective means to connect the melodic material
to higher structural units. J. C. Bach's influence, however, endured in Mozart's handling of melody, and his keyboard production constitutes, in spite of some flaws, a noteworthy example of elegance and craftsmanship
Cuidado de enfermagem, com visão holográfica, na abordagem de idosas com depressão, utilizando a terapia floral de Bach
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde. Programa de Pós-Graduação em Enfermagem.Este estudo teve como objetivo investigar a relevância do cuidado de Enfermagem com visão holográfica, incluindo a aplicação dos florais de Bach em idosas com depressão, usando o referencial de Enfermagem de Betty Neuman. Foi utilizada uma metodologia qualitativa com abordagem analítica e analógica. A técnica da abordagem foi o estudo de casos, aplicando-se a entrevista semi- estruturada e a escala de Beck - Depression Inventory - BDI, para semi-quantificar a depressão. Foi feito análise estatística das médias dos BDIs. O diagnóstico de depressão foi baseado no DSM IV, feito por uma geriatra, que também fez a avaliação desses casos após o período estipulado de tratamento (20 semanas). As idosas participavam das sessões de terapia de grupo, realizadas por uma psicóloga. As voluntárias foram 13 idosas, acima de 60 anos, em depressão, assistidas no Centro de Reabilitação de Idosos Damásio Barbosa de Franca - João Pessoa - Paraíba, no período de julho de 2002 a fevereiro de 2003. Os dados foram colhidos através das respostas dos questionários. Entre as informações foram identificados os estressores, os fenômenos de Enfermagem, segundo a Classificação Internacional da Prática de Enfermagem (CIPE) - versão ALFA, e as metas a serem trabalhadas através da terapia floral de Bach. Os fenômenos de Enfermagem ligados aos estressores intrapessoais mais freqüentes foram: depressão; dificuldade para dormir; isolamento social; tristeza; desesperança; falta de apetite; ansiedade; culpa; medo; insônia; fadiga; baixa auto-estima; interação social prejudicada; sono intermitente; déficit nutricional. Dentre os ligados aos estressores intra e interpessoal associados, destacaram-se: falta de apetite; culpa; distúrbio do relacionamento familiar; insônia; crenças de valores; processo familiar alterado; interação social prejudicada. Dos ligados aos estressores intra, inter e extrapessoais perceberam-se: distúrbio no relacionamento familiar; interação social limitada. Percebeu-se que os estressores que mais contribuíram para a depressão em idosos estavam ligados aos intrapessoais, fossem eles associados ou não a outros estressores. A intervenção da enfermagem foi à prescrição dos florais de Bach. Pode-se concluir que o cuidado de Enfermagem com visão holográfica, incluindo a aplicação dos florais de Bach, em idosas com depressão, contribuiu para a redução significante dos estressores nessas pacientes. Assim, a sua aplicabilidade é possível uma vez que a teoria escolhida trabalha com os estressores, sendo esses harmonizados através da terapia floral de Bach, que atua nas causas dos desconfortos, equilibrando o indivíduo e devolvendo-lhe a saúde
Aklimatyzacja cebul narcyza (Narcissus L.) otrzymanych w kulturach zarodków somatycznych
No full textWarunki podczas fazy in vitro wpływają następczo na aklimatyzację roślin narcyza (Narcissus L.) 'Carlton'. Procesowi aklimatyzacji najlepiej poddają się cebule o masie z przedziału 401-500 mg. Najwyższą przeżywalnością (99%) charakteryzują się cebule chłodzone 9 tygodni, hodowane na pożywkach z sacharozą w stężeniu 3%. Podwyższenie stężenia sacharozy nie wpływa na wzrost liczby cebul rozwijających liście. W przypadku cebul nie chłodzonych dodatek do pożywki gibereliny w stężeniu 5 µM wpływa korzystnie zarówno na procent cebul rozwijających liście, jak i procent przeżywalności ex vitro. Proces aklimatyzacji przeżywały cebule do których ukorzenienia nie stosowano auksyny lub użyto IAA. Cebule narcyza chłodzone w temperaturze 5°C przez 9 tygodni aklimatyzują się najlepiej.Acclimatization of daffodil (Narcissus L.) 'Carlton' bulbs depends on the in vitro culture conditions. Bulbs of 401-500 mg gave the greatest transplantation success. The highest bulb recovery was observed when the bulbs were cooled for 9 weeks and cultured on media supplemented with 3% sucrose. Elevated concentrations of sucrose in the medium gave no benefit on the increase of bulb emergence. The addition of gibberellin at 5 µM to the medium has beneficial effect on ex vitro bulb emergence percent as well as on bulb recovery percent. Bulbs rooted on auxin free medium or a medium supplemented with IAA best recovered the acclimatization process
Morfogeneza w kulturach in vitro eksplantatów Narcissus L. ‘Carlton’ izolowanych z pąków kwiatowych w stadium Pc w zależności od poziomu cytokininy i auksyny
No full textThe effect of the concentration and proportion of growth regulators in an initial medium on Narcissus L. ‘Carlton’ morphogenesis in cultures of Pc stage flower bud ex-plants was investigated. Ovary and flower stem explants were cultured on solid Mura-shige and Skoog (MS) media with cytokinin – 6-Benzyladenine (BA) or Zeatin (ZEA) (0.5–50 μM) – in combination with auxin – 4-Amino-3,5,6-trichloropicolinic acid (Picloram), 2,4-Dichlorophenoxyacetic acid (2,4-D) or α-Naphthaleneacetic acid (NAA) (1–50 μM). The ratios of cytokinin and auxin in the initial medium determined the morphogenetic pathways and the level of cytokinin proved to be a critical factor. Somatic embryogenesis was achieved for a cytokinin and auxin ratio of 1:1–10, bulb organogenesis – for a 1:0.4–1 ratio and rhizogenesis – for a 1:20–100 ratio. The minimum concentration of cytokinin in the initial medium for somatic embryo and bulb formation was 5 μM. A lower level of cy-tokinin (0.5 μM) resulted in rhizogenesis. Considering the effect of auxin, Picloram stimulated the initiation of somatic embryos and the 2,4-D enhanced embryo maturation and conversion.Zbadano wpływ stężenia i proporcji regulatorów wzrostu w pożywce ini-cjalnej na morfogenezę narcyza (Narcissus L.) ‘Carlton’ w kulturach eksplantatów izolo-wanych z pąków kwiatowych w stadium Pc. Fragmenty zalążni i pędów kwiatowych kul-tywowano na pożywce stałej MS uzupełnionej regulatorami wzrostu: cytokininą – BA lub zeatyna (0.5–50 μM) i auksyną – Picloram, 2,4-D lub NAA (1–50 μM). Zastosowane proporcje regulatorów wzrostu determinowały kierunki morfogenezy, a poziom cytokininy okazał się czynnikiem krytycznym. Somatyczną embriogenezę uzyskano w przypadku proporcji cytokininy do auksyny – 1:1–10, cebule przybyszowe – 1:0,4–1, korzenie przy-byszowe – 1:20–100. Minimalne stężenie cytokininy w pożywce do inicjacji somatycznej embriogenezy i formowania cebul przybyszowych wyniosło 5 μM. Niższe stężenie cyto-kininy (0.5 μM) wywoływało ryzogenezę. Obserwując wpływ auksyny na proces soma-tycznej embriogenezy, stwierdzono, że Picloram stymulował inicjację zarodków soma-tycznych narcyza, natomiast 2,4-D przyspieszało ich dojrzewanie i konwersję
Central limits of squeezing operators
No full textIn [1] we have proved a quantum De Moivre-Laplace theorem based on a
modification of the Giri-von Waldenfels quantum central limit theorem. In [2] P.A. Meyer outlined a method based on direct calculations which, taking advantage of the explicit structure of the algebra of matrices, allows a drastic simplification of the proof of the main result of the first part of our paper and relates it with a similar result obtained, independently and simultaneusly, by Parthasarathy [5].
In the first part of the present note we simplify the Parthasarathy-Meyer method and extend it to deal with arbitrary d-dimensional Bernoulli
processes, where is a natural integer (cfr. Sections (3),(4).
We also prove another statement in Meyer's note (cf. Theorem (5.1)).
Finally (Section (6)) we show that the method of proof used in [1] allows, with minor modifications, to solve the problem of the central limit approximation of the squeezing states - a problem left open in [1] and to which, due to the nonlinearity of the coupling, Parthasarathy-Meyer
direct computational method cannot be applied

Heme oxygenase-1, carbon monoxide, and bilirubin induce tolerance in recipients toward islet allografts by modulating T regulatory cells
No full textHeme oxygenase-1 (HO-1) induction in, or carbon monoxide (CO), or bilirubin administration to, donors and/or recipients frequently lead to long-term survival (>100 days) of DBA/2 islets into B6AF1 recipients. We tested here whether similar treatments show value in a stronger immunogenetic combination, i.e., BALB/c to C57BL/6, and attempted to elucidate the mechanism accounting for tolerance. Induction of HO-1, administering CO or bilirubin to the donor, the islets or the recipient, prolonged islet allograft survival to different extents. Combining all the above treatments (the "combined" protocol) led to survival for >100 days and antigen-specific tolerance to 60% of the transplanted grafts. A high level of forkhead box P3 (Foxp3) and transforming growth factor beta (TGF-beta) expression was detected in the long-term surviving grafts. With the combined protocol, significantly more T regulatory cells (Tregs) were observed surrounding islets 7 days following transplantation. No prolongation of graft survival was observed using the combined protocol when CD4(+)CD25(+) T cells were predepleted from the recipients before transplantation. In conclusion, our combined protocol led to long-term survival and tolerance to islets in the BALB/c to C57BL/6 combination by promoting Foxp3(+) Tregs; these cells played a critical role in the induction and maintenance of tolerance in the recipient.--Lee, S. S., Gao, W., Mazzola, S., Thomas, M. N., Csizmadia, E., Otterbein, L. E., Bach, F. H., and Wang, H. Heme oxygenase-1, carbon monoxide, and bilirubin help recipients tolerate islet allografts by modulating T regulatory cells
Nowa metoda mikrorozmnazania tulipana [Tulipa genseriana L.] z tkanek zalazni
No full textW celu przyspieszenia reprodukcji tulipana (Tulipa gesneriana L.) prowadzono badania nad możliwością mikrorozmnażania z tkanek zalążni, na drodze somatycznej embriogenezy. Materiał wyjściowy stanowiły fragmenty zalążni izolowane z cebul chłodzonych i nie chłodzonych dwóch odmian Apeldoorn' i 'Red Matador'. Eksplantaty wykładano na pożywki zawierające różne proporcje zawartości Picloramu i BAP. Formowanie kalusa zachodziło na wszystkich pożywkach lecz kalus embriogeniczny był indukowany tylko na podłożach zawierających proporcjonalnie wyższe stężenie auksyny do cytokininy. Przebieg somatycznej embriogenezy był najkorzystniejszy u eksplantatów izolowanych z chłodzonych cebul tulipana, a jego wydajność zależała od genotypu. Odmiana Apeldoorn' dawała wyższą średnią liczbę zarodków (16,7) w porównaniu do 'Red Matador' (9,7). Badania stopnia ploidalności roślin, uzyskanych w wyniku konwersji z zarodków somatycznych, nie wykazały w testowanych próbach obecności haploidów ani osobników o zwiększonej liczbie chromosomów. Stwierdzono, że proponowana metoda mikrorozmnażania tulipanów z tkanek ścianek zalążni charakteryzuje się wyższym współczynnikiem rozmnażania niż dotychczas znane metody.The object of this study was the possibility to improve the multiplication rate of micropropagated tulips (Tulipa gesneriana L.). Ovary explants were isolated from chilled (12 weeks) and unchilled bulbs of Apeldoorn' and 'Red Matador' cultivars and exposed to various concentrations of of Picloram and BAP Plants were generated through somatic embryogenesis by an intermediatery callus phase. Callus formation was observed on all medium types but the embryogenic callus was formed only on the media containing more Picloram than BAP. High frequency of embryos' induction took place in the explants isolated from chilled bulbs. Efficiency of embryogenesis depended on the genotype. 'Apeldoorn' cv. produced more somatic embryos then the 'Red Matador' cv. (16.7 and 9.7 embryos per one explant, respectively). Cytological analysis did not reveal any changes in chromosome number of regenerated explants
