Factors influencing the germination of myrtle (Lagerstroemia speciosa (L.) Pers. and L-floribunda Jack) seeds

Gibberellic acid and potassium nitrate did not promote the germination of myrtle seeds when tested at 20/30degreesC (16/8h). Germination was promoted considerably by alternating temperatures. The results of an investigation on a two-dimensional temperature gradient plate showed that myrtle seeds germinated most rapidly (within 14 days) and fully (all viable seeds) at 35/22.5degreesC (16/8 h) and similar regimes. Tests on five seed lots of Lagerstroemia speciosa and L. floribunda showed the efficacy of the alternating temperature regime of 35/20degreesC (16/8 h) in promoting germination. Thus we recommend myrtle seeds be tested for germination in this regime for 28 days.

The child in wolf’s clothing: the meanings of the ‘wolf’ and questions of identity in Jack London’s White Fang

The criticism of Jack London’s work has been dominated by a reliance upon ideas of the ‘real’, the ‘authentic’ and the ‘archetypal’. One of the figures in London’s work around which these ideas crystallize is that of the ‘wolf’. This article will examine the way the wolf is mobilized both in the criticism of Jack London’s work and in an example of the work: the novel White Fang (1906). This novel, though it has often been read as clearly delimiting and demarcating the realms of nature and culture, can be read conversely as unpicking the deceptive simplicity of such categories, as troubling essentialist notions of identity (human/animal, male/female, white/Indian) and as engaging with the complexity of the journey in which a ‘small animal … becomes human-sexual by crossing the infinite divide that separates life from humanity, the biological from the historical, “nature” from “culture” ’ (Althusser 1971: 206).

Carpenter Syndrome: Extended RAB23 Mutation Spectrum and Analysis of Nonsense-mediated mRNA Decay

Carpenter syndrome, a rare autosomal recessive disorder characterized by a combination of craniosynostosis, polysyndactyly, obesity, and other congenital malformations, is caused by mutations in RAB23, encoding a member of the Rab-family of small GTPases. In 15 out of 16 families previously reported, the disease was caused by homozygosity for truncating mutations, and currently only a single missense mutation has been identified in a compound heterozygote. Here, we describe a further 8 independent families comprising 10 affected individuals with Carpenter syndrome, who were positive for mutations in RAB23. We report the first homozygous missense mutation and in-frame deletion, highlighting key residues for RAB23 function, as well as the first splice-site mutation. Multi-suture craniosynostosis and polysyndactyly have been present in all patients described to date, and abnormal external genitalia have been universal in boys. High birth weight was not evident in the current group of patients, but further evidence for laterality defects is reported. No genotype-phenotype correlations are apparent. We provide experimental evidence that transcripts encoding truncating mutations are subject to nonsense-mediated decay, and that this plays an important role in the pathogenesis of many RAB23 mutations. These observations refine the phenotypic spectrum of Carpenter syndrome and offer new insights into molecular pathogenesis. (C) 2011 Wiley-Liss, Inc.

"Jag är bara här tillfälligt" : Identitetsskapande i arbetarromaner från 2010-talet av Sara Beischer och Jack Hildén

Syftet med denna uppsats är att reda ut hur huvudgestalterna i Sara Beischers roman Jag ska egentligen inte jobba här (2012) och Jack Hildéns roman Vi, vi vaktmästare (2014) formar identiteter utifrån arbetet samt hur de ser på sig själva utanför arbetet. Detta gör jag genom att utgå ifrån definitioner av begreppen "identitet" och "prekariat". Analysen visar att romankaraktärerna skapar identiteter kopplade till arbetet genom att studera hur deras kollegor beter sig och därefter härma detta beteende. De gör det även genom att bära arbetskläder, lära sig arbetsuppgifterna samt genom att differentiera sig mot arbetsgivaren respektive tjänstemännen på samma arbetsplats. Den identitet de har utanför arbetet är kopplad till kultur och åtskild från identiteten som arbetare.

Caio Fernando Abreu e Jack Kerouac : diálogos que atravessam as Américas

A finalidade deste estudo é analisar, do ponto de vista da Literatura Comparada, as relações existentes entre contos do escritor Caio Fernando Abreu e o romance On the Road, do norte-americano Jack Kerouac. Com o objetivo de apreender o diálogo entre os textos, a investigação desenvolve-se desde o exame do estilo de vida das personagens até as condições históricas nas quais foram produzidas as obras. Dessa forma, focaliza-se o local que ocupa a produção literária do escritor gaúcho, a partir das relações inter-literárias com a realidade cultural do seu tempo. Pretendeu-se verificar, através da Literatura Comparada, de que modo a obra de Caio absorve os influxos da obra de Kerouac. Assim, examina-se a apropriação cultural estrangeira através da recepção, em Caio, da literatura “beat”. O estudo aborda questões referentes ao sujeito, à liberdade, à introspecção, à fragmentação, à identidade, ao estranhamento, ao desejo, à autonomia, relacionando-as à construção da linguagem e à representação da visão de mundo dos autores. Para tanto, foram considerados alguns momentos históricos do final do século XX, como a Segunda Guerra Mundial, a Guerra Fria, o Macartismo e a ditadura militar brasileira. Nesse contexto, intensifica-se, de um lado, o desejo de livre arbítrio e, de outro, a imobilidade resultante da falta de esperança. A partir desses dados, analisa-se a atmosfera vivida e representada nas obras de Caio e Kerouac. Dessa forma, o trabalho desenvolve a hipótese de que Caio Fernando Abreu absorve aspectos da filosofia “beat”, assimila-os e os transforma para adaptá-los ao seu contexto histórico e cultural.

Efeitos da escarificação química e da concentração de nitrogênio sobre a germinação e o desenvolvimento in vitro de Vanilla planifolia Jack ex Andr. (Orchidaceae: Vanilloideae)

Vanilla planifolia é uma espécie com grande valor comercial, porém sua propagação é dificultada devido à baixa germinação de suas sementes. No presente estudo procurou-se avaliar a influência da escarificação destas sementes por meio da imersão em H2SO4 concentrado durante 60, 120 e 180 segundos, bem como de diferentes concentrações de nitrogênio sobre a germinação e o desenvolvimento das plântulas. Sessenta segundos de escarificação e 25% de nitrogênio no meio de cultura proporcionaram os melhores resultados sobre a germinação e desenvolvimento de V. planifolia, constituindo-se em um procedimento viável para a produção comercial dessa espécie.

Age polyethism in the swarm-founding wasp Metapolybia miltoni (andena & carpenter) (Hymenoptera: Vespidae; Polistinae, epiponini)

In Epiponini division of labor is associated with age polyethism and individual task specialization. We observed worker activities in three colonies of Metapoybia miltoni in Brazil. We analyzed differences of task allocation among age groups. Old workers tend to forage more than young, but age polyethism was less evident in other tasks. Age composition of population could be a determinant factor in task allocation. Workers are probably allocating to perform tasks according to colony needs, and not to individual's age. Considering age population in studies of division of labor could help to understand how colonies respond to different situations.
