Reciprocal and advanced generation hybrids between Corymbia citriodora and C-torelliana: forestry breeding and the risk of gene flow

Corymbia F1 hybrids have high potential for plantation forestry; however, little is known of their reproductive biology and potential for genetic pollution of native Corymbia populations. This study aims to quantify the influence of reproductive isolating barriers on the success of novel reciprocal and advanced generation Corymbia hybrids. Two maternal taxa, Corymbia citriodora subsp. citriodora and Corymbia torelliana, were pollinated using five paternal taxa, C. citriodora subsp. citriodora, C. torelliana, one C. torelliana x C. citriodora subsp. citriodora hybrid and two C. torelliana x C. citriodora subsp. variegata hybrids. Pollen tube, embryo and seed development were assessed. Reciprocal hybridisation between C. citriodora subsp. citriodora and C. torelliana was successful. Advanced generation hybrids were also created when C. citriodora subsp. citriodora or C. torelliana females were backcrossed with F1 hybrid taxa. Prezygotic reproductive isolation was identified via reduced pollen tube numbers in the style and reduced numbers of ovules penetrated by pollen tubes. Reproductive isolation was weakest within the C. citriodora subsp. citriodora maternal taxon, with two hybrid backcrosses producing equivalent capsule and seed yields to the intraspecific cross. High hybridising potential was identified between all Corymbia species and F1 taxa studied. This provides opportunities for advanced generation hybrid breeding, allowing desirable traits to be amplified. It also indicates risks of gene flow between plantation and native Corymbia populations.

Evolution of microstructure and texture during deformation and recrystallization of heavily rolled Cu-Cu multilayer

A Cu-Cu multilayer processed by accumulative roll bonding was deformed to large strains and further annealed. The texture of the deformed Cu-Cu multilayer differs from the conventional fcc rolling textures in terms of higher fractions of Bs and RD-rotated cube components, compared with the volume fraction of Cu component. The elongated grain shape significantly affects the deformation characteristics. Characteristic microstructural features of both continuous dynamic recrystallization and discontinuous dynamic recrystallization were observed in the microtexture measurements. X-ray texture measurements of annealing of heavily deformed multilayer demonstrate constrained recrystallization and resulted in a bimodal grain size distribution in the annealed material at higher strains. The presence of cube- and BR-oriented grains in the deformed material confirms the oriented nucleation as the major influence on texture change during recrystallization. Persistence of cube component throughout the deformation is attributed to dynamic recrystallization. Evolution of RD-rotated cube is attributed to the deformation of cube components that evolve from dynamic recrystallization. The relaxation of strain components leads to Bs at larger strains. Further, the Bs component is found to recover rather than recrystallize during deformation. The presence of predominantly Cu and Bs orientations surrounding the interface layer suggests constrained annealing behavior.

Coastal brownfields and adaptation to climate change: Discussions on potential hazards from contaminated groundwater displacement due to saltwater incursion

Toxic-waste associated with coastal brownfield sites can pose serious risks to human and environmental health. In light of anticipated sea-level rise (SLR) due to global climate change, coastal brownfields require heightened attention. The primary intent of this study is to pose questions and encourage discussion of this problem among policy makers. Impacts from SLR on coastal zones are examined within a brownfield policy framework and, current coastal brownfield policy discussions with respect to SLR are also examined. (PDF contains 4 pages)

Impacto econômico do absenteísmo de enfermagem por doença em um hospital universitário do Rio de Janeiro-RJ

Trata-se de uma pesquisa documental, retrospectiva de fonte secundária,que adota uma abordagem quantitativa descritiva-exploratória. A partir da constatação de altos índices de absenteísmo nas unidades hospitalares, despertou-se o interesse em estudar os custos diretos das doenças ocupacionais que levam aos afastamentos e seu impacto econômico para o orçamento de recursos humanos de um hospital universitário do Rio de Janeiro. Neste contexto, definiu-se como objeto de estudo, o impacto econômico do absenteísmo por doença na equipe de enfermagem e, como objetivos: identificar as causas prevalentes de afastamentos no hospital universitário, de acordo com Classificação Internacional de Doenças e Problemas Relacionados a Saúde (CID-10); estimar os custos diretos mínimos das doenças que afastaram o trabalhador de enfermagem; estimar o custo real aproximado do absenteísmo relacionado a 1 (um) dia de trabalho prestado pelos trabalhadores de enfermagem, com projeção de 1 (um) mês e 1(um) ano numa visão operacional do Sistema Único de Saúde (SUS). Foi utilizada uma amostra estratificada de prontuários dos profissionais de saúde da equipe de enfermagem (enfermeiros e técnicos de enfermagem), a partir do seguinte critério de inclusão: profissionais de enfermagem concursados com afastamento no ano de 2010 e com diagnóstico médico determinante do afastamento, definido claramente. Para a coleta das informações foi feita a apreciação dos documentos arquivados no Serviço de Saúde do Trabalhador do hospital estudado e contou com a apreciação de especialistas médicos relativos aos grupos de diagnósticos estudados, orientados por roteiros criados pela pesquisadora. Os dados foram analisados e armazenados no programa Statistical Package for the Social Sciences (SPSS) versão 15 e no editor Microsoft excel 2003. Dentre os resultados obtidos tiveram destaque para as seguintes causas de afastamento, respectivamente, às doenças do sistema osteomuscular, os fatores que influenciam o estado de saúde e o contato com serviços de saúde, os transtornos mentais e comportamentais, as lesões, envenenamento e outras consequencias de causas externas e, as doenças do sistema circulatório, que representam um custo estimado aproximado de R$ 2,6 milhões. Pôde-se constatar que o impacto econômico do absenteísmo decorrentes dos agravos à saúde para o orçamento de recursos humanos do hospital universitário foi de aproximadamente 2,7%. O custo real aproximado do absenteísmo de enfermagem por dia, foi avaliado em R$ 92,50, tendo projeção mensal de R$ 2.775,00 e anual de R$ 33.300,00. Recomenda-se avaliar o absenteísmo dos profissionais regularmente para identificar as causas reais do absenteísmo por doença, a fim de definir metas para os programas de intervenção à saúde dos trabalhadores e promover uma Gestão participativa que favoreça uma análise do processo de trabalho no que concerne o atendimento das necessidades de saúde e operacionais da força de trabalho, determinantes do absenteísmo.

Extraction, PCR amplification, and sequencing of mitochondrial DNA from scent mark and feces in the giant panda

To expand the feasibility of applying simple, efficient, non-invasive DNA preparation methods using samples that can be obtained from giant pandas living in the wild, we investigated the use of scent markings and fecal samples. Giant panda-specific oligonucleotide primers were used to amplify a portion of the mitochondrial DNA control region as well as a portion of the mitochondrial DNA cytochrome b gene and tRNA(Thr) gene region. A 196 base pair (bp) fragment in the control region and a 449 bp fragment in the cytochrome b gene and tRNA(Thr) gene were successfully amplified. Sequencing of polymerase chain reaction (PCR) products demonstrated that the two fragments are giant panda sequences. Furthermore, under simulated field conditions we found that DNA can be extracted from fecal samples aged as long as 3 months. Our results suggest that the scent mark and fecal samples are simple, efficient, and easily prepared DNA sources. (C) 1998 Wiley-Liss, Inc.

Shape evolution of Ge/Si(001) islands induced by strain-driven alloying

The shape evolution of Ge/Si(001) islands grown by ultrahigh vacuum chemical vapor deposition were investigated by atomic force microscopy at different deposition rates. We find that, at low deposition rates, the evolution of islands follows the conventional pathway by which the islands form the pyramid islands, evolve into dome islands, and dislocate at a superdome shape with increasing coverage. While at a high deposition rate of 3 monolayers per minute, the dome islands evolve towards the pyramids by a reduction of the contact angle. The presence of the atomic intermixing between the Ge islands and Si substrate at high deposition rate is responsible for the reverse evolution. (C) 2001 American Institute of Physics.
