Project description:Plate tectonics is largely responsible for material and heat circulation in Earth, but for unknown reasons it does not exist on Venus. The strength of planetary materials is a key control on plate tectonics because physical properties, such as temperature, pressure, stress, and chemical composition, result in strong rheological layering and convection in planetary interiors. Our deformation experiments show that crustal plagioclase is much weaker than mantle olivine at conditions corresponding to the Moho in Venus. Consequently, this strength contrast may produce a mechanical decoupling between the Venusian crust and interior mantle convection. One-dimensional numerical modeling using our experimental data confirms that this large strength contrast at the Moho impedes the surface motion of the Venusian crust and, as such, is an important factor in explaining the absence of plate tectonics on Venus.
Project description:BackgroundSocial circus is a branch of circus that primarily focuses on personal and community development, rather than an elite level of professional artistry required of traditional circus. Social circus engages participants in circus activities such as juggling and acrobatics with therapeutic aims such as building confidence or developing life skills. While there is a growing body of literature around social circus, there is currently limited literature exploring the interface between social circus and occupational therapy theory.ObjectiveThis study is aimed at examining existing examples of social circus for people with disability (via YouTube videos) through the lens of the Model of Human Occupation (MOHO) to consider the link between social circus and contemporary occupational therapy practice.MethodsThe study utilised video analysis as the guiding methodology. A two-part qualitative thematic analysis was conducted on transcripts of YouTube video audio and on-screen text, as well as visual analysis of the corresponding imagery.ResultsSocial circus provides people with disabilities opportunities to actively participate and experience dignity of risk, independence, and autonomy, in a safe and inclusive environment amongst others. As a highly flexible activity (in structure, timing, tasks, outcomes, and environments), social circus accommodated differences in capacities and provided opportunity for the development of skills, both circus-specific and generalisable to everyday life. Social circus allowed people with disability to shape new identities as performers, friends, and members of a community.ConclusionSocial circus offers a unique means for successfully attaining and achieving a wide range of occupational outcomes for people with and without disability across a diverse range of settings. Utilising an occupational therapy lens led to insights around the social circus environments, development of identity and transference of circus skills to everyday tasks and occupations, that were not previously acknowledged in the social circus literature. Our findings support social circus implementation and collaboration within contemporary occupational therapy practice.
Project description:Saccharomonospora azurea Runmao et al. 1987 is a member of the genus Saccharomonospora, which is in the family Pseudonocardiaceae and thus far poorly characterized genomically. Members of the genus Saccharomonospora are of interest because they originate from diverse habitats, such as leaf litter, manure, compost, the surface of peat, and moist and over-heated grain, and may play a role in the primary degradation of plant material by attacking hemicellulose. Next to S. viridis, S. azurea is only the second member in the genus Saccharomonospora for which a completely sequenced type strain genome will be published. Here we describe the features of this organism, together with the complete genome sequence with project status 'Improved high quality draft', and the annotation. The 4,763,832 bp long chromosome with its 4,472 protein-coding and 58 RNA genes was sequenced as part of the DOE funded Community Sequencing Program (CSP) 2010 at the Joint Genome Institute (JGI).
Project description:In the present study, the detection of a pantropic canine coronavirus (CCoV) strain in a dog with lethal diarrhoea is reported. RT-PCR and real-time RT-PCR assays were used for the detection, characterization and quantitation of CCoV. Sequence and phylogenetic analysis of the CCoV NA/09 revealed a high degree of sequence identity with the pantropic strain CB/05, indicating the presence of CB/05-like pantropic strains in Greece. The absence of the 38-nucleotide deletion in ORF3b, which is characteristic of CB/05, indicates the need to identify new genetic markers for pantropic variants of CCoV, probably in the spike-protein gene region.
Project description:Saccharomonospora cyanea Runmao et al. 1988 is a member of the genus Saccharomonospora in the family Pseudonocardiaceae that is moderately well characterized at the genome level thus far. Members of the genus Saccharomonospora are of interest because they originate from diverse habitats, such as soil, leaf litter, manure, compost, surface of peat, moist, over-heated grain, and ocean sediment, where they probably play a role in the primary degradation of plant material by attacking hemicellulose. Species of the genus Saccharomonospora are usually Gram-positive, non-acid fast, and are classified among the actinomycetes. S. cyanea is characterized by a dark blue (= cyan blue) aerial mycelium. After S. viridis, S. azurea, and S. marina, S. cyanea is only the fourth member in the genus for which a completely sequenced (non-contiguous finished draft status) type strain genome will be published. Here we describe the features of this organism, together with the draft genome sequence, and annotation. The 5,408,301 bp long chromosome with its 5,139 protein-coding and 57 RNA genes was sequenced as part of the DOE funded Community Sequencing Program (CSP) 2010 at the Joint Genome Institute (JGI).
