Distribution patterns, weed incursions and origins of terrestrial flora at the Capricorn-Bunker Islands, Great Barrier Reef, Australia

A checklist of vascular plants of the 15 Capricorn-Bunker Islands (CBI) (lat 23° 11’ to 24° 07’S; long 151° 43’ to 152° 43’E) compiled from 2007/08 surveys, recorded 131 vascular plant species including 44 (34%) native and 87 (66%) naturalized species from 55 families and 104 genera. New native records include Hernandia nymphaeifolia and Boerhavia sp. (Bargara L.Pedley 5382). An increase of about 35 exotic species over 23 years was recorded indicating a weed incursion rate of 1.5 species per annum. Cakile edentula (13 islands) and Solanum americanum (12 islands) are the most widespread exotic weeds. The naturalised flora ranged from 5% at Erskine Island (low disturbance) to 68% at Lady Elliot Island (very high disturbance). Achyranthes aspera, Argusia argentea and Pisonia grandis are the only species found on all 15 islands. Six indigenous species are limited to one island: Boerhavia sp. (Bargara L.Pedley 5382), Calophyllum inophyllum, Clerodendrum inerme, Hernandia nymphaeifolia, Stephania japonica and Ximenia americana. Patterns of plant distributions, diversity and origin are discussed. Eleven indigenous species reach their southern limit at the CBI, indicating connectivity with the Indo-Pacific region. PATN analyses using native flora generated two island groups. Tryon, Heron, North West, Masthead, Wilson, Wreck and Erskine Islands are the most closely related islands. Another group of related islands includes North Reef, Lady Musgrave, Fairfax Islands, Hoskyn and One Tree Islands. With the inclusion of the exotic flora, Lady Elliot Island separated into its own distinct group. Greater conservation management efforts are required to control and minimise the introduction of exotic weed species to islands with high human visitation

Plant strategies, dispersal and origins of flora at the northern Coral Sea Islands Territory, Australia

A checklist of vascular plants of Coringa-Herald National Nature Reserve (CHNNR) (17º 11’S, 149º 00’ E to 16º 23’S, 150º 30’E and Willis Island (16º 24’S, 149º 58’E) at the northern Coral Sea Islands Territory of Australia compiled during 2006/07 surveys, recorded 30 species including 18 species indigenous to the Coral Sea Islands (60%), 10 exotic species (33%) and two that were planted (7%). Plant life-forms included: 5 species of trees and tall shrubs (17%), 2 species of low shrubs (6.5%), 21 herbs (70%), and 2 vine/creepers (6.5%). Plant dispersal for the 30 species is predominantly by human activities (40%), ocean currents (33%) and seabirds (27%). The garden species and dispersal modes at Willis Island indicate that non-residential casual human visitation at CHNNR has at present had little effect on establishment of exotic weeds. Resilience of leverage flora, floristic diversity and species origins of CHNNR are discussed in relation to its connectivity with the Melanesian region due to the South Equatorial Current operating in the region. Colubrina asiatica was recorded as a new record for oceanic islands in Australian territories. Previously recorded Ximenia americana and Digitaria ctenantha are considered locally extinct. Pattern analyses indicate that cays of similar size and vegetation structure are the most similar in floristic composition. Willis Island flora is relatively dissimilar to the CHNNR cays, due to the influence of anthropogenic activities associated with a staffed weather station

The detectability of free-phase migrating CO₂:A rock physics and seismic modelling feasibility study

AbstractSubsurface monitoring is essential for the successful implementation and public acceptance of CO2 storage. Injected CO2 will need to be monitored to verify the successful containment within its intended formation, and to ensure no loss of containment within the storage complex. The ability for seismic techniques to monitor structurally trapped CO2 has been successfully demonstrated due to the changes in the acoustic properties of the reservoir produced by the displacement of brine by less dense and more compressible CO2. However, the ability for seismic methods to detect free-phase migrating CO2 is still moderately understood. In order to assess the feasibility for seismic monitoring of a migrating front, we estimate the time-lapse signal over a theoretical, clean, homogeneous sandstone reservoir through the application of a three-stage model-driven workflow consisting of fluid-flow, rock physics and seismic forward modelling. To capture the range of responses which could be encountered, two end-member fluid distribution models were used: uniform saturation and the modified patchy saturation model. Analysis of the time- lapse survey highlights the importance of determining and understanding the fluid distribution model impacting the range of velocities prior to generating and interpreting the seismic response. This change in velocity is shown to be directly related to the volume of CO2 occupying the pore-space of a migrating plume front. This highlights the fact that the detectability of a migrating front is a site specific issue which not only depends on the geophysical parameters of the seismic survey but also on the geological variations and spatial distribution in the reservoir

TesisLIMAEscuela Profesional de ContabilidadT02326TPC 2 G15 2017FinanzasEl objetivo de la investigación fue determinar la relación del estado de flujos de efectivo y la solvencia de las empresas comercializadoras en el Perú en los periodos 2010 al 2015. También determinamos la relación de la actividad de operación, inversión y financiamiento con el endeudamiento patrimonial, el endeudamiento del activo total y la cobertura de gastos financieros. Aplicamos el análisis descriptivo – correlacional y el diseño no experimental de corte transversal en la data de empresas comerciales que informan a la Superintendencia de Mercado de Valores (SMV) en los periodos trimestrales del año 2010 - 2015. La actividad de operación, inversión y financiamiento se ha utilizado como una medida del Estado de Flujos de Efectivo, mientras que el endeudamiento patrimonial, el endeudamiento del activo total y la cobertura de gastos financieros obtenidos se utilizan como un indicador de la solvencia de una empresa. Los resultados revelan cuanto mayor sea el flujo obtenido del ejercicio anterior, mayor será la confianza de los bancos en la empresa y, consecuentemente, mayor será la posibilidad de endeudarse frente a terceros y mayor será el acceso a la financiación con terceros, así mismo; cuando el endeudamiento patrimonial y el endeudamiento del activo total es menor, mayor serán las actividades de inversión. Se recomienda a las empresas del sector comercialización del Perú usar como herramienta el EFE ya que esta herramienta podría ser usada como una oportunidad para obtener financiamiento externo y demostrar la solvencia de la empresa, por ello nos parece conveniente darle la importancia a este estado financiero

Made by hand

Although the mainstream animation industry has adopted digital production methods, the attraction of laborious hand-made methods for making animation persists in the independent sector. The chapter considers how ‘craftivist’ opposition to mechanical, technological and digital techniques is validated in this community of practice through ideas that haptic knowledge by skilled physical labour and an exploration of materiality, autographic mark-making and imperfection (Wabi-sabi) are guarantors of authenticity and individuality that can only be carried out by hand. Why is this? What ideas and assumptions can be seen to underpin the notions of craft and crafting? Tracing connections between craft and activism since the Industrial Revolution, this chapter critically reflects on discourses of craft and the handmade through reference to Ruskin (1851), Morris (1892), Hobsbawm (2000), Thompson (1980), Benjamin (1935), Krauss (2000) and Takahashi (2005). Whereas the experimental animation community privileges analogue, handmade processes that appear to oppose and critique commercial animation production, building upon Warburton (2016) and Frayling (2017) it is argued here that this approach is underpinned by nostalgia and often faked. What looks like a hand-painted animation could actually be a simulation that was ‘painted’ in a software package: a pastiche of manual labour. Aesthetics alone do not guarantee that a work of art opposes the mainstream. Instead of recycling the past to create ‘artistic’ animation, it is argued in the conclusion that contemporary practitioners can equally investigate issues of labour and materiality through digital tools and virtual materials such as in the ‘ugly’ CGI animation of Nikita Daikur (2017)

Circadian control of mouse heart rate and blood pressure by the suprachiasmatic nuclei:behavioral effects are more significant than direct outputs

Diurnal variations in the incidence of events such as heart attack and stroke suggest a role for circadian rhythms in the etiology of cardiovascular disease. The aim of this study was to assess the influence of the suprachiasmatic nucleus (SCN) circadian clock on cardiovascular function. mice and WT. However, there was also a modest circadian rhythm of resting HR and BP that was independent of LA.If appropriate methods of analysis are used that take into account sleep and locomotor activity level, mice are a good model for understanding the contribution of circadian timing to cardiovascular function. Future studies of the influence of sleep and wakefulness on cardiovascular physiology may help to explain accumulating evidence linking disrupted sleep with cardiovascular disease in man

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy
