    A Bacillus velezensis strain from the rhizosphere of Sporobolus airoides (Torr.) Torr . , a grass in central-north México, was isolated during a biocontrol of phytopathogens scrutiny study. The 2A-2B strain exhibited at least 60% of growth inhibition of virulent isolates of phytopathogens causing root rot. These phytopathogens include Phytophthora capsici , Fusarium solani , Fusarium oxysporum and Rhizoctonia solani . Furthermore, the 2A-2B strain is an indolacetic acid producer, and a plant inducer of PR1, which is an induced systemic resistance related gene in chili pepper plantlets. Whole genome sequencing was performed to generate a draft genome assembly of 3.953 MB with 46.36% of GC content, and a N50 of 294,737. The genome contains 3713 protein coding genes and 89 RNA genes. Moreover, comparative genome analysis revealed that the 2A-2B strain had the greatest identity (98.4%) with Bacillus velezensis.

    A greenhouse experiment was performed to determine the uptake of trace elements and radionuclides from uranium mill tailings by native plant species. Four-wing saltbush and alkali sacaton were grown in alkaline tailings covered with soil and in soil alone as controls. The tailings material was highly enriched in Ra-226, Mo, U, Se, V, and As compared with three local soils. The shrub grown in tailings had elevated concentrations of Mo, Se, Ra-226, U, As, and Na compared with the controls. Alkali sacaton contained high concentrations of Mo, Se, Ra-226, and Ni when grown on tailings. Molybdenum and selenium concentrations in plants grown in tailings are above levels reported to be toxic to grazing animals. These results indicate that the bioavailability of Mo and Se in alkaline environments makes these elements among the most hazardous contaminants present in uranium mill wastes

    Hydrated leaves of the resurrection grass Sporobolus elongatus are not desiccation tolerant (DT), but moderate to severe drought stress can induce their DT with the leaves remain attach to drying intact plants. In vivo protein synthesis was studied with SDS-page of extracts of leaves of intact drying plants of S. elongatus (a desiccation-Tolerant grass (DT)) and S. pyramidalis (a desiccation-sensitive species (DS)). Free proline increased in drying leaves. Soluble sugar contents also increased with drying but were less than fully hydrated leaves at 8% RWC. Total protein also showed an increase with an exception at 8% RWC which showed a decrease. SDS-page of extracts of drying leaves of both DT and DS plants were studied as relative water contents (RWC) decreased. In first phase, DT species at 58% RWC (80-51% RWC range), two proteins increased in contents. In the second phase, at 8% (35-4% RWC range) two new bands increased and two bands decreased. In leaves of DS species some bands decreased as drying progressed. Also, as drying advanced free proline increased in DT species. Total protein increased as drying increased but at 8% RWC decreased. All data of results are consistent with current views about studied factors and their roles during drying and induction of desiccation tolerance in DT plants.

These include the quick distribution of materials and the lifting of large and heavy items. One of these machines which has now attained a widespread use is the tower crane, both of the fixed and moveable type, either on tyres, rails, or of the climbing type. Although these cranes have been known for the last fifty years, their full development only began after the last World War. Their most usual features and varieties make it possible to classify these cranes in a table, which includes most of the models now in standard use.Los nuevos volúmenes de edificación, y los nuevos sistemas, como la prefabricación, han exigido el desarrollo de la maquinaria auxiliar correspondiente, con el fin de poder cubrir las necesidades de alimentación de la obra, reparto de materiales y elevación de cargas y piezas voluminosas.

    Antimicrobial and antioxidant activities of two plants Echinochloa colona (Linn.) Link and Sporobolus coromandelianus (Retz.) Kunth, were carried out. The results revealed that the extracts of both plants were active against Gram positive bacteria, i.e. Staphylococcus aureus and Streptococcus pneumoniae and Gram negative bacteria, i.e. Escherichia coli and Pseudomonas aeruginosa as well as the fungal strains Aspergillus oryzae and Aspergillus niger. The most significant results were obtained from the methanolic and petroleum ether extracts of E. colona, i.e. 24 +- 2.64 mm and 23 +- 2.64 mm against S. aureus, respectively. A significant inhibition zone of 23.66 +- 1.52 was observed by petroleum ether extract of S. coromandelianus. The chloroform extracts of S. coromandelianus showed an inhibition zone 72.33 +- 4.09 mm against A. oryzae and 66.33 +- 1.15 mm against A. niger. The antioxidant activity was evaluated using five approaches, i.e. 2,2'-azinobis(3-ethylbenzothiazoline)-6-sulphonic acid (ABTS) method; ferric reducing antioxidant power (FRAP) assay, metal chelating assay, total phenolic contents (TPC) and flavonoid contents. The results showed that the methanolic extracts of both plants possessed significant antioxidant activity. The results also indicated that methanolic extract of E. colona had total phenolic and flavonoid contents, i.e. 734.25 and 7774.54 mg/ml, however, methanolic extract of S. coromandelianus had phenolic and flavonoid contents, i.e. 366.75 and 3010.90 mg/ml.

    Twenty-eight indigenous ewe lambs (6 months of age and 14.4 kg body weight (BW)) were used to evaluate the effect of feeding Sporobolus grass hay (SGH) as the only source of forage on growth, and feed and water intakes. The ewe lambs were randomly and equally allocated to two treatment groups (14 lambs/group). The ewe lambs in group 1 (treatment 1) received SGH, while lambs in group 2 (treatment 2) received Rhodes grass hay (RGH) as the only source of forage. Water was available at all times for both treatment groups. Sporobolus grass was irrigated with brackish water of high salt content (20,000 ppm) and grown in saline desert lands (sabkha) in the United Arab Emirates. The average daily dry matter intake was significantly (P  .05) between the two groups at all stages. From these data, we conclude that SGH can replace Rhodes hay in sheep diet without significant effect on sheep performance.

    The Torres Strait is a reef-laden stretch of water lying south of New Guinea and north of the tip of the Cape York Peninsula of northeastern Australia. Because of its location and geologic structure it is particularly hazardous to shipping, and limits passage through the area. It was suggested that nuclear explosives might be used to create a safe shipping channel through the strait, and in this paper that possibility will be explored. While the construction of the Torres Strait Channel appears feasible from both a technical and an economic point of view, a great deal of further research will have to be done in a number of areas. The Channel would be a great economic boost to northwestern Australia and to trade between southeast Asia and Australia, but its effect on the Great Barrier Reef and the people of the region will require serious consideration.

  19. TORR system polishes oily water clean

    2002-01-01

    The TORR (total oil recovery and remediation) system utilizes a specially patented polymer material, similar to styrofoam, which is used to get rid of non-soluble hydrocarbons from water. An application in Fort Smith, Northwest Territories, is described where it was used to recover diesel oil, which had been seeping into the groundwater over a period of 20 years. About 100,000 gallons of heating oil had leached into the water; TORR removed the non-soluble hydrocarbons, while another piece of equipment removed the soluble portions. After treatment the water tested consistently at non-detectable levels and was clean enough to be discharged into the town's sewer system. The system is considered ideal for oil spills clean-up underground, onshore, or the open sea, but it also has many potentially useful applications in industrial and oilfield applications. Water used in steam injection and water floods to produce heavy oil and SAGD applications are some of the obvious ones that come to mind. Cleaning up the huge tailings ponds at the mining and processing of oil sands, and removing diluent from water that is used to thin out bitumen in pipelines so that it can be transported to processing plants, are other promising areas of application. Several field trials to test the effectiveness of the system in these type of applications are scheduled for the summer and fall of 2002

    Full Text Available The symbolic tower of the horticultural exhibition, held recently in Vienna, is a 260 m high structure made of reinforced concrete. Of the total height, 181 m constitute the stem, and the rest is made up of a metallic needle. Inside the tower there are two lifts, each with capacity for 15 people, and a travelling velocity of 6.5 m/sec. In the top 31 ms of the stem there are two terraces, a bar and a restaurant: they provide a wonderful view of the city and the surrounding district. The vertical outline of the stem is an arc of a parabola. A sliding formwork has been utilized for its construction, and a height of 4 m has been concreted every day: this has meant a movement of 25 cm of the formwork every hour. The tower has a weight of 17000 tons, which imposes large loads on the foundation. To withstand these, the foundations have been made in the form of a truncated cone, with a cylindrical hollow core. The base of the cone has an external diameter of 31 m, and an internal diameter of 10.20 m. A compression hoop strengthens the joint between the foundation cone and the stem itself. Although this tower is located in the centre of the city, it harmonizes very well with the surrounding buildings.La torre simbólica de la Exposición de Horticultura, celebrada recientemente en Viena (Austria, es de hormigón armado y tiene 260 m de altura total, de los que 181 corresponden al fuste y el resto a una aguja metálica.

    Directory of Open Access Journals (Sweden)

    Sharmin Islam

    Full Text Available Isolation of gene transcripts from desiccated leaf tissues of the resurrection grass, Sporobolus stapfianus, resulted in the identification of a gene, SDG8i, encoding a Group 1 glycosyltransferase (UGT. Here, we examine the effects of introducing this gene, under control of the CaMV35S promoter, into the model plant Arabidopsis thaliana. Results show that Arabidopsis plants constitutively over-expressing SDG8i exhibit enhanced growth, reduced senescence, cold tolerance and a substantial improvement in protoplasmic drought tolerance. We hypothesise that expression of SDG8i in Arabidopsis negatively affects the bioactivity of metabolite/s that mediate/s environmentally-induced repression of cell division and expansion, both during normal development and in response to stress. The phenotype of transgenic plants over-expressing SDG8i suggests modulation in activities of both growth- and stress-related hormones. Plants overexpressing the UGT show evidence of elevated auxin levels, with the enzyme acting downstream of ABA to reduce drought-induced senescence. Analysis of the in vitro activity of the UGT recombinant protein product demonstrates that SDG8i can glycosylate the synthetic strigolactone analogue GR24, evoking a link with strigolactone-related processes in vivo. The large improvements observed in survival of transgenic Arabidopsis plants under cold-, salt- and drought-stress, as well as the substantial increases in growth rate and seed yield under non-stress conditions, indicates that overexpression of SDG8i in crop plants may provide a novel means of increasing plant productivity.

    Codisposal of flue gas desulfurization (FGD) sludge with low-volume generating station waste simplifies disposal but creates a saline, high boron (B) waste that may be difficult to revegetate after site closure. Studies on a delta of waste material in a codisposal pond at the coal-fired Coronado Generating Station in eastern Arizona evaluated management techniques, amendments, and plants for revegetating this material. One study investigated leaching and ridging techniques and a second evaluated amendment with manure, wood shavings, and fly ash, Four salt-tolerant grass species and four saltbushes (A triplex spp,) were evaluated in the two studies. Criteria for success were high survival rates and growth, as measured by grass height and shrub height x width. Leaching salts and B from the waste was not necessary for establishment and growth of transplanted shrubs and grasses. Ridging was not a successful technique, due to limited moisture and high levels of salinity and B on these structures. Gardner saltbush (A, gardneri (Moq.) D, Dietr.) and a fourwing saltbush (A. canescens (Pursh) Nutt,) accession from the site were the most successful shrubs and alkali sactonn (Sporobolus airoides (Torr,) Torr. `Saltalk`) was the most successful grass at this disposal pond. Amendment with manure, wood shavings, or fly ash did not increase plant survival. Growth of grasses was improved with all amendments and was greatest with manure, but growth of shrubs was not improved with any amendment. 33 refs., 8 tabs.

    Full Text Available Francisco de la Torre's Works, published by Quevedo in 1631, enclose a second part, described in later years as an «appendix», with translations that did not belong in the original project prepared by the author some decades before. The summary of the 1588 license for printing describes the work's content as «lyric and adonic verse, and bucolic», without mentioning the translations. The new date throws into question the participation of Almeida and Brocense in the preparation and transmission of the manuscript that came to Quevedo. Therefore, the volume of 1631 cannot be considered as an example of salmantin group's collective poetical essay. Related chronological considerations also throw new light on the relationship between the author and Fernando de Herrera.Las Obras de Francisco de la Torre, publicadas por Quevedo en 1631, incluyen una segunda parte, que más tarde se llamaría «apéndice», con traducciones ajenas al proyecto inicial preparado por el propio autor décadas antes. El sumario de la licencia de impresión de 1588 describe el contenido de la obra aprobada como «los versos líricos y adónicos y la bucólica», sin mencionar las traducciones. La nueva fecha lleva a cuestionar el protagonismo de Almeida y el Brócense en la preparación y transmisión del manuscrito que más tarde llegaría a Quevedo. El volumen de 1631, por lo tanto, no puede considerarse como un exponente de un ejercicio poético colectivo del círculo salmantino. Los datos cronológicos también permiten replantear la relación del autor con Fernando de Herrera.

    The upper crustal bimodal Torres del Paine Intrusion, southern Chile, consists of the lower Paine-Mafic- Complex and the upper Paine-Granite. Geochronologically this bimodal complex is not well studied except for a few existing data from Halpern (1973) and Sanchez (2006). The aim of this study is to supplement the existing data and to constrain the age relations between the major magmatic pulses by applying high precision U-Pb dating on accessory zircons and 40Ar/39Ar-laser-step-heating-ages on biotites from the Torres del Paine Intrusion. The magmatic rocks from mafic complex are fine to medium-grained and vary in composition from quartz- monzonites to granodiorites and gabbros. Coarse-grained olivine gabbros have intruded these rocks in the west. The granitic body is represented by a peraluminous, biotite-orthoclase-granite and a more evolved leucocratic granite in the outer parts towards the host-rock. Field observations suggest a feeder-zone for the granite in the west and that the granite postdates the mafic complex. Two granite samples of the outermost margins in the Northeast and South were analyzed. The zircons were dated by precise isotope-dilution U-Pb techniques of chemically abraded single grains. The data are concordant within the analytical error and define weighted mean 206/238U ages of 12.59 ± 0.03 Ma and 12.58 ± 0.01 Ma for the two samples respectively. A 40Ar/39Ar-age for the second sample yield a date of 12.37 ± 0.11 Ma. Three 40Ar/39Ar -ages of biotites were obtained for rocks belonging to the mafic complex. A hbl-bio- granodiorite from the central part, approximately 150 m below the subhorizontal contact with the granite, gives an age of 12.81 ± 0.11 Ma. A hbl-bio-granodiorite and an olivine-gabbro west of the feeder-zone date at 12.42 ± 0.14 Ma and 12.49 ± 0.11 Ma, respectively. The obtained older age of 12.81 Ma for the granodiorite in the central part is consistent with structural relationships of brittle fracturing of the mafic

    Full Text Available Effective algorithms of physical media numerical modeling problems’ solution are discussed. The computation rate of such problems is limited by memory bandwidth if implemented with traditional algorithms. The numerical solution of the wave equation is considered. A finite difference scheme with a cross stencil and a high order of approximation is used. The DiamondTorre algorithm is constructed, with regard to the specifics of the GPGPU’s (general purpose graphical processing unit memory hierarchy and parallelism. The advantages of these algorithms are a high level of data localization, as well as the property of asynchrony, which allows one to effectively utilize all levels of GPGPU parallelism. The computational intensity of the algorithm is greater than the one for the best traditional algorithms with stepwise synchronization. As a consequence, it becomes possible to overcome the above-mentioned limitation. The algorithm is implemented with CUDA. For the scheme with the second order of approximation, the calculation performance of 50 billion cells per second is achieved. This exceeds the result of the best traditional algorithm by a factor of five.

    Full Text Available This article, attempts to demonstrate one of several forms of dialogue between the portuguese literatures, proposes an anlysis of the short story Amor, by Clarice Lispector and the poem Amor de Clarice, by Rui Torres. Considering that the poem is from of a preexisting text, or an “hypotext”, as defined by Gennete, analyse these productions from the perspective of intersemiotic translation according the works of Julio Plaza and Claus Clüver, since these theorists treat the “translation” less as a transfer of meaning from the original, which should be subordinate to it, an activity which involves creating thus transforming. Also, the Torres’s (rewrinting proposes, as a poet, a way to make the contemporary literary criticism. Thus, this study will develop towards analyzing how text elements clariceano were (reproduced, (recreated, transformed in the poem Rui and how a work of twenty-first century can shed new questions, new perspectives and new reflections to text in the last century.

    With increasing implementation of casemix-based funding for hospitals, quantitative data were needed to confirm the clinical impression that treating Aboriginal (compared with non-Aboriginal) inpatients consumes significantly more resources. Utilisation data, collected over a three-month period in 10 hospitals, were used to determine a cost per inpatient episode, which was grouped according to AN-DRG-3 to give a cost per AN-DRG for Aboriginal and Torres Strait Islander (ATSI) patients and non-ATSI patients. ATSI patients had consistently longer average length of stay and significant variation in relative frequency of admissions, compared with non-ATSI patients, with higher prevalences of infectious diseases. Degenerative and neoplastic conditions were more common in non-ATSI patients. There were significant differences in casemix-adjusted costs per patient episode (ATSI, $1856; non-ATSI, $1558; P < 0.001). Our study has quantified differential resource consumption between two Australian populations, and highlights the need for recognition of some hospitals' atypical populations and special funding requirements.

    Full Text Available Tinantia anomala (Torr. C.B. Clarke (Commelinaceae is an annual plant endemic to central Texas in the United States and Durango in northern Mexico. T. anomala has zygomorphic flowers with three different petals, androecium consists of six various stamens and gynoecium consists of three carpels. Furthermore in T. anomala’s flowers there are many staminal hairs (Faden 2006. Its semi-succulent, grass-like leaves emerge in late fall and remain green throughout the cold months. It grows rapidly in early spring and blooms mid-spring (from March to May. A few weeks later the fruits (capsules with four seeds usually appear. This entire cycle is usually completed by summer, when the plant has often turned yellow and limp. We studied T. anomala due to the occurrence of two types of strikingly different stamens occur in one flower. According to available literature, one type of the stamens (the upper one with smaller anthers produces sterile pollen grains which do not participate in fertilization but only attract insects. The other type, i.e. the lower stamens with bigger anthers can form abundant pollen grains used for pollination (Simpson et al. 1986. Our aim was to investigate type of pollination of T. anomala. Using many microscopic methods we were able to analyze and compare the morphology of two types of anthers and staminal hairs in T. anomala’s flowers. We also investigated this species in terms of development of its gametophytes. An embryo sac develops according to the type of Polygonum. Pollen grains develop during different ways depending on the chemical composition of each anther. We identified that the insects of Thysanoptera which preys on the withered flowers T. anomala could be responsible for pollination of this species under greenhouse condition.

    In the presence of trimethylamine N-oxide (TMAO), the TorS-TorR two-component regulatory system induces the torCAD operon, which encodes the TMAO respiratory system of Escherichia coli. The sensor protein TorS detects TMAO and transphosphorylates the response regulator TorR which, in turn, activates transcription of torCAD. The torR gene and the torCAD operon are divergently transcribed, and the short torR-torC intergenic region contains four direct repeats (the tor boxes) which proved to be ...

    There is concern from within Aboriginal and Torres Strait Islander communities about the lack of access to alcohol withdrawal management ('detox') services. Outpatient detox is described within national Australian guidelines as a safe option for selected drinkers. However, uncertainly exists as to how suited Aboriginal and Torres Strait Islander peoples are to this approach. 
 Consultations were conducted with stakeholders of four health services providing outpatient detox for Aboriginal and Torres Strait Islander peoples in NSW. Thematic analysis was performed to determine elements perceived as important for success. Key themes that emerged were individual engagement, flexibility, assessment of suitability, Aboriginal staff and community engagement, practical support, counselling, staff education and support, coping with relapse and contingency planning. 
 There is a need to improve access to alcohol detox services for Aboriginal and Torres Strait Islander peoples. The outpatient setting seems to be a feasible and safe environment to provide this kind of service for selected drinkers.

    The Torres del Paine National Park (TPNP) is located on the southern limit of the Andean Southern Ice Field, part of the Magallanes and Antartica Chilena region, in the province of Ultima Esperanza. The TPNP has a very heterogeneous climate due to orographic influence and wet air masses from the Pacific. The geology is basically Cretaceous metasedimentary rocks and Miocene granitic plutons and batholiths. We studied the main soils and geoenvironments of Mt Ferrier mountain and its surroundings, based on soils , landforms and vegetation aspects. The geoenvironmental stratification was based on the combined variation and integration of pedo-litho-geomorphological features with the vegetation. WE used detailed geological maps, a DEM and slope maps and WorlView II satellite images. Fifteen soils profiles were sampled and classified according to Soil Taxonomy (2010) at all genovironments, ranging from 50 m a.s.l to the at high plateau just below the permanent snowline, under periglacial conditions (~1004m asl). Three soil temperature and moisture monitoring sites were set, allowing for 24 consecutive months (2011 to 2013). Seven geoenvironments were identified with distinct soil and landform characteristics, all with a similar geological substrate. The landform and vegetation have a strong connection with the landscape dynamic, controlling erosional and depositional processes, resulting from glacier advances and retreats in the Late Quaternary. Wind blown materials is widespread, in the form of loess material, accumulating in the higher parts of the landscape. On the other hand, accumulation of organic matter in the water-saturated depressions is common in all altitudes. Generally the soils are acidic and dystrophic, with little exceptions. The following geoenvironments were identified: Periglacial Tundra, Loess slopes, Talus and scarpmentd, Fluvio-glacial terraces, Fluvio-lacustrine plains, Moraines and Paleodunes. The regional pedology show the occurrence of five soil

    Gambling problems appear to be more prevalent in the Australian Aboriginal and Torres Strait Islander population than in the non-Indigenous population. Although gambling harms can be significant, treatment-seeking rates are low. The Delphi expert consensus method was used to develop a set of guidelines on how a family or community member can assist an Aboriginal or Torres Strait Islander person with gambling problems. Building on a previous systematic review of websites, books and journal articles a questionnaire was developed that contained items about the knowledge, skills and actions needed for supporting an Aboriginal or Torres Strait Islander person with gambling problems. These items were rated over three rounds by an expert panel comprising professionals who provide treatment to or conduct research with Aboriginal and Torres Strait Islander people with gambling problems. A total of 22 experts rated 407 helping statements according to whether they thought the statements should be included in these guidelines. There were 225 helping statements that were endorsed by at least 90% of participants. These endorsed statements were used to develop the guidelines. Experts were able to reach substantial consensus on how someone can recognise the signs of gambling problems and support an Aboriginal or Torres Strait Islander person to change.

    Australian Aboriginal and Torres Strait Islander people have higher rates of morbidity and mortality thanother Australians. One proposed strategy to improve this situation is to increase the participation ofAboriginal and Torres Strait Islander people, including Aboriginal and Torres Strait Islander nurses, inthe health workforce. Although the numbers of Aboriginal and Torres Strait Islander students under-taking tertiary nursing courses have increased, completion rates have not kept pace. The study aimedto describe Aboriginal and Torres Strait Islander nursing students’ experiences of enablers for successfulcourse completion and to develop a narrative of student experience. A qualitative study using a strengths-based approach with a narrative analysis of semi-structured interview data was conducted across fourschools of Nursing in Queensland, Australia. Eight final-year Aboriginal and Torres Strait Islander nursingstudents volunteered to participate in the study. A collective story with the overarching plotline Creatingwalking tracks to success was developed. Six threads of experience emerged: Making a difference, Valu-ing Indigeneity, Healing strength of connections, Resisting racism, Embracing support, and perseveringtowards completion. Key success factors included resilient attributes, building supportive connectionsand having positive expectations of the future, along with sustained institutional support from Aboriginaland Torres Strait Islander nurse academics and clinicians. Development of tailored resilience-buildingtraining for Aboriginal and Torres Strait Islander nursing students and appointment of Aboriginal andTorres Strait Islander academics in Schools of Nursing that include such students may facilitate futuresuccessful completions in other programs.

    Seedlings of Salicornia bigelovii Torr. were treated with different concentrations of NaCl (0, 100, 300, 600 mmol/L). Ion contents, Na(+) subcelluar localization, photosynthetic rate, ultrastructure of chloroplast and other parameters were measured. The data showed both fresh and dry weight of whole plant of Salicornia bigelovii Torr. under salinity were higher than the control. When NaCl concentration is about 300 mmol/L Salicornia bigelovii Torr. grow strongest. The contents of Na(+) and Cl(-) and c(Na)/c(K) in shoots increased with the salinity. Both Na(+) and Cl(-) were mainly transported to shoots. Ion X-ray microanalysis indicated Na(+) was mainly compartmentalized into vacuoles. Photosynthetic rate increased with the salinity under NaCl 100-300 mmol/L, but declined under NaCl 600 mmol/L. Ultrastructure of chloroplast was destroyed by NaCl 600 mmol/L.

    Aboriginal and Torres Strait Islander Australians experience high rates of mental illness and psychological distress compared to their non-Indigenous counterparts. E-mental health tools offer an opportunity for accessible, effective, and acceptable treatment. The AIMhi Stay Strong app and the ibobbly suicide prevention app are treatment tools designed to combat the disproportionately high levels of mental illness and stress experienced within the Aboriginal and Torres Strait Islander community. This study aimed to explore Aboriginal and Torres Strait Islander community members' experiences of using two culturally responsive e-mental health apps and identify factors that influence the acceptability of these approaches. Using qualitative methods aligned with a phenomenological approach, we explored the acceptability of two culturally responsive e-mental health apps through a series of three 3-hour focus groups with nine Aboriginal and Torres Strait Islander community members. Thematic analysis was conducted and coresearcher and member checking were used to verify findings. Findings suggest strong support for the concept of e-mental health apps and optimism for their potential. Factors that influenced acceptability related to three key themes: personal factors (eg, motivation, severity and awareness of illness, technological competence, and literacy and language differences), environmental factors (eg, community awareness, stigma, and availability of support), and app characteristics (eg, ease of use, content, graphics, access, and security and information sharing). Specific adaptations, such as local production, culturally relevant content and graphics, a purposeful journey, clear navigation, meaningful language, options to assist people with language differences, offline use, and password protection may aid uptake. When designed to meet the needs of Aboriginal and Torres Strait Islander Australians, e-mental health tools add an important element to public health

    Aboriginal and Torres Strait Islander peoples continue to be pathologised in medical curriculum, leaving graduates feeling unequipped to effectively work cross-culturally. These factors create barriers to culturally safe health care for Aboriginal and Torres Strait Islander peoples. In this pilot pre-post study, the learning experiences of seven medical students and four medical registrars undertaking clinical placements at an urban Aboriginal and Torres Strait Islander primary healthcare service in 2014 were followed. Through analysis and comparison of pre- and post-placement responses to a paper-based case study of a fictitious Aboriginal patient, four learning principles for medical professionalism were identified: student exposure to nuanced, complex and positive representations of Aboriginal peoples; positive practitioner role modelling; interpersonal skills that build trust and minimise patient-practitioner relational power imbalances; and knowledge, understanding and skills for providing patient-centred, holistic care. Though not exhaustive, these principles can increase the capacity of practitioners to foster culturally safe and optimal health care for Aboriginal peoples. Furthermore, competence and effectiveness in Aboriginal health care is an essential component of medical professionalism.

    This review was undertaken to identify evidence-based practice guidelines to support the care needs of Aboriginal and Torres Strait Islander clients residing in residential aged-care facilities. A systematic literature review was undertaken. An electronic search of online databases and subsequent manual retrieval process was undertaken to identify relevant reports and studies that explored interventions for care of an Aboriginal and Torres Strait Islander person. Very limited published material identified strategies necessary within residential aged care. Sixty-seven articles were considered for inclusion, and a subsequent review resulted in 34 being included due to direct alignment with the study aim. Strategies recommended within the review cover areas such as care, communication, palliative care, activities and the environment. Care for an Aboriginal and Torres Strait Islander person in an Australian residential aged-care facility requires a collaborative and individual approach. Cultural safety principles should be maintained across a culturally competent workforce. Aboriginal and Torres Strait Islander persons in care is a significant experience that should not be considered 'routine' as there is much to consider in the care of this person and their community. © 2011 The Author.

    In Australia, Home Medicines Review (HMR) has been found to be an important tool to raise awareness of medication safety, reduce adverse events and improve medication adherence. Aboriginal and Torres Strait Islander people are 'underserviced' by the HMR program and are the most likely of all Australians to miss out on HMRs despite their high burden of chronic disease and high rates of hospitalisation due to medication misadventure. The goal of this study was to explore Aboriginal and Torres Strait Islander perspectives of the Home Medicines Review program and their suggestions for an 'improved' or more readily accessible model of service. Eighteen semi-structured focus groups were conducted with 102 Aboriginal and Torres Strait Islander patients at 11 Aboriginal Health Services (AHSs). Participants who were multiple medication users and understood English were recruited to the study by AHS staff. Seven focus groups were conducted for people who had already used the HMR program (User, n=23) and 11 focus groups were conducted for people who had not had an HMR (Non User, n=79). Focus groups were recorded, de-identified and transcribed. Transcripts were coded and analysed for themes. Focus groups continued and concepts were explored until no new findings were being generated and thus saturation of data occurred. Focus group participants who had not had an HMR had little or no awareness of the HMR program. All the participants felt that lack of awareness and promotion of the HMR program were contributing factors to the low uptake of the HMR program by Aboriginal and Torres Strait Islander people. Most participants felt that an HMR would assist them to better understand their medicines, would empower them to seek information about medicines, would improve relationships with health professionals and would increase the likelihood of medication adherence. Most of the User participants reported that the HMR interview had been very useful for learning more about their

    Full Text Available Through the historiographic data and the architectonic and archaeologic study of the Roman remains found during the 18th and 19th Centuries, today disappeared, we present here an hypothesis about the Augustean construction of a big tower in Campa Torres. This would be identified as a lighthouse controlling the entrance of the Gijón's bay. The commemorative stone of Cn. Calpurnius Piso (CIL II, 2703, dated on 9-10 AD, was founded in this building. We cannot accept the identification of this monument as one of the wellknown Arae Sestianae. This light-house, with a symbolic character as well a purpose of informing to the mariners the access of the harbour, would be erected in a militarized region recently conquered.Partiendo del análisis exhaustivo de la documentación historiográfica y del estudio arqueoarquitectónico de los restos arqueológicos exhumados en los siglos XVIII y XIX, hoy en día destruidos, planteamos la hipótesis de que en la Campa Torres se erigió en época augustea una gran torre con función de faro, que señalaba el acceso a la bahía de Gijón. Dicho monumento, del que procede la lapida calpurniana datada en el 9-10 d. C. (CIL II, 2703, no puede de ninguna manera interpretarse como una de las famosas Aras Sestianas. Con un carácter claramente simbólico, el faro constituiría un hito señalizador en el paisaje de una región militarizada y recientemente conquistada, además de desempeñar un claro papel de apoyo a la navegación cantábrica, al indicar la entrada al mejor puerto astur.

    Objective To provide an overview of previous reviews of programs that aimed to improve nutritional status or diet-related health outcomes for Aboriginal and Torres Strait Islander peoples, in order to determine what programs are effective and why. Methods A systematic search of databases and relevant websites was undertaken to identify reviews of nutrition interventions for Aboriginal and Torres Strait Islander Australians. Pairs of reviewers undertook study selection and data extraction and performed quality assessment using a validated tool. Results Twelve papers reporting 11 reviews were identified. Two reviews were rated high quality, three were rated medium and six were rated low quality. The reviews demonstrated that a positive effect on nutrition and chronic disease indicators can be a result of: 1) incorporating nutrition and breastfeeding advice into maternal and child health care services; and 2) multifaceted community nutrition programs. The evidence suggests that the most important factor determining the success of Aboriginal and Torres Strait Islander food and nutrition programs is community involvement in (and, ideally, control of) program development and implementation. Conclusions Community-directed food and nutrition programs, especially those with multiple components that address the underlying causes of nutrition issues, can be effective in improving nutrition-related outcomes. What is known about the topic? More effective action is urgently required in order to reduce the unacceptable health inequalities between Aboriginal and Torres Strait Islander peoples and non-Indigenous Australians. Food insecurity and nutrition-related chronic conditions are responsible for a large proportion of the ill health experienced by Australia's First Peoples. What does this paper add? This narrative overview of 11 reviews published between 2005 and 2015 provides a synthesis of the current evidence for improving Aboriginal and Torres Strait Islander nutrition

    As well as providing primary health care services, Aboriginal and Torres Strait Islander health workers are known to significantly contribute to the overall acceptability, access and use of health services through their role of cultural brokerage in the communities within which they work. As such they are uniquely positioned to positively influence health improvements for this vulnerable population. This study sought to identify key areas that both Aboriginal and Torres Strait Islander and non-Indigenous health professionals working within Indigenous communities felt were important in providing support for their roles. This group of workers require support within their roles particularly in relation to cultural awareness and capability, resource provision, educational opportunities, collaboration with colleagues and peers, and professional mentorship.

    The two-component systems, which could sense and respond to environmental changes, widely exist in bacteria as a signal transduction pathway. The bacterial CckA/CtrA, ArcA/ArcB and PhoP/PhoQ two-component systems are associated with initiation of DNA replication and cell division, however, the effects of the TorS/TorR system on cell cycle and DNA replication remains unknown. The TorS/TorR system in Escherichia coli can sense changes in trimethylamine oxide (TMAO) concentration around the cells. However, it is unknown if it also affects initiation of DNA replication. We detected DNA replication patterns in ΔtorS and ΔtorR mutant strains by flow cytometry. We found that the average number of replication origins (oriCs) per cell and doubling time in ΔtorS mutants were the same while the average number of oriCs in ΔtorR mutants was increased compared with that in wild-type cells. These results indicated that absence of TorR led to an earlier initiation of DNA replication than that in wild-type cells. Strangely, neither overexpression of TorR nor co-expression of TorR and TorS could restore ΔtorR mutant phenotype to the wild type. However, overexpression of SufD in both wild type and ΔtorR mutants promoted initiation of DNA replication, while mutation of SufD delayed it in ΔtorR mutants. Thus, TorR may affect initiation of DNA replication indirectly through regulating gene expression of sufD.

  6. Using Metasynthesis to Develop Sensitising Concepts to Understand Torres Strait Islander Migration

    Full Text Available Emerging research indicates that more and more Indigenous peoples will be forced to migrate due to climate change. Current responses focus on mitigation and adaptation strategies. One such group, Torres Strait Islander people are already moving for other reasons and existing vulnerabilities compound levels of disadvantage when moving. It will be important to understand Torres Strait Islander people’s experiences of contemporary movements in order to inform policy development and facilitate the process of migration and resettlement as movement increases. A synthesis of existing studies would allow the development of sensitising concepts that could inform future research in the Torres Strait Islander context. This article presents a metasynthesis of six qualitative studies of the experiences of different Indigenous and minority groups at various stages of migration, displacement and resettlement. Articles were selected on contemporary movements (2001-2011 and importantly the inclusion of first person voice. Reciprocal translation was used to synthesise common themes and a core construct. The overarching construct that became apparent from the metasynthesis was ‘continuity of being’ through staying connected to self, family and culture. Three themes emerged: ‘freedom to be’, ‘staying close’ and ‘forming anchor’. These were enacted through people valuing their personal, social, religious and political freedom and recognising the importance of maintaining or forming strong social and family networks. When researching the experiences of Torres Strait Islanders it will be necessary to focus on motivations for moving, and understand the processes for staying connected to kin and homeland in order to achieve the desired outcomes of successful resettlement under conditions of uncertainty.

    Polycystic ovary syndrome (PCOS) is a chronic endocrine syndrome in reproductive-aged women which is very common among Aboriginal and Torres Strait Islander women. The objective of this study was to conduct a process evaluation of a pilot clinic on Thursday Island which aimed to provide a comprehensive evidence-based service for women with PCOS throughout the Torres Strait. Mixed-method evaluation at 12 months comprising a medical record audit, semi-structured interviews and focus group discussions. Primary care. Audit of n = 11 clinics (n = 36 women), qualitative semi-structured interviews with n = 8 clinicians and focus group discussions with n = 8 women. (i) Fidelity to evidence-based guidelines, (ii) barriers and enablers to women using the service, (iii) the ability to meet the needs of women and the community. The clinic was largely successful in providing evidence-based care with up to 78% of women receiving recommended cardiometabolic screening, 100% emotional screening and 89% lifestyle management despite the remoteness of the clinic and limited financial and human resources. Health care providers report sustainability of the clinic will be dependent on factors including staffing, administrative support and inclusion of Aboriginal and Torres Strait Islander health workers. While the clinic has been largely successful there are areas identified for potential improvement and to facilitate sustainability which should be considered before up-scaling this model to a national level. These include systems, administrative and staffing support, engaging with other community services to facilitate lifestyle changes and ongoing engagement and upskilling of Aboriginal and Torres Strait Islander health care providers. © 2016 National Rural Health Alliance Inc.

    Gaps exist in researchers' understanding of the 'practice' of community governance in relation to research with Aboriginal and Torres Strait Islander peoples. We examine Aboriginal community governance of two rural NSW research projects by applying principles-based criteria from two independent sources. One research project possessed a strong Aboriginal community governance structure and evaluated a 2-year healthy lifestyle program for children; the other was a 5-year cohort study examining factors influencing the mental health and well-being of participants. The National Health and Medical Research Council of Australia's 'Values and ethics: guidelines for ethical conduct in Aboriginal and Torres Strait Islander research' and 'Ten principles relevant to health research among Indigenous Australian populations' described by experts in the field. Adopt community-based participatory research constructs. Develop clear governance structures and procedures at the beginning of the study and allow sufficient time for their establishment. Capacity-building must be a key component of the research. Ensure sufficient resources to enable community engagement, conduct of research governance procedures, capacity-building and results dissemination. The implementation of governance structures and procedures ensures research addresses the priorities of the participating Aboriginal and Torres Strait Islander communities, minimises risks and improves outcomes for the communities. Principles-based Aboriginal and Torres Strait Islander community governance of research is very achievable. Next steps include developing a comprehensive evidence base for appropriate governance structures and procedures, and consolidating a suite of practical guides for structuring clear governance in health research. © 2015 National Rural Health Alliance Inc.

    Health promotion for Australian Aboriginal and Torres Strait Islander communities and their people has generally had limited efficacy and poor sustainability. It has largely failed to recognise and appreciate the importance of local cultures and continues to have minimal emphasis on capacity building, community empowerment and local ownership. Culturally Appropriate Health Promotion is a framework of principles developed in 2008 with the World Health Organization and the Global Alliance for Health Promotion. It serves as a guide for community-focused health promotion practice to be built on and shaped by the respect for understanding and utilisation of local knowledge and culture. Culturally Appropriate Health Promotion is not about targeting, intervening or responding. Rather, it encourages health programme planners and policymakers to have a greater understanding, respect, a sense of empowerment and collaboration with communities, and their sociocultural environment to improve health. This commentary aims to examine and apply the eight principles of Culturally Appropriate Health Promotion to the Australian Aboriginal and Torres Strait Islander context. It proposes a widespread adoption of the framework for a more respectful, collaborative, locally suitable and therefore appropriate approach to Australian Aboriginal and Torres Strait Islander health promotion.

    Bone mineral density (BMD) has been reported to be both higher and lower in Indigenous women from different populations. Body composition data have been reported for Indigenous Australians, but there are few published BMD data in this population. We assessed BMD in 161 Indigenous Australians, identified as Aboriginal (n=70), Torres Strait Islander (n=68) or both (n=23). BMD measurements were made on Norland-XR46 (n=107) and Hologic (n=90) dual-energy X-ray absorptiometry (DXA) machines. Norland BMD and body composition measurements in these individuals, and also in 36 Caucasian Australians, were converted to equivalent Hologic BMD (BMD(H)) and body composition measurements for comparison. Femoral neck (FN) and lumbar spine Z-scores were high in Indigenous participants (mean FN Z-score: Indigenous men +0.98, pAboriginal and/or Torres Strait Islander than Caucasian participants, after adjusting for age, gender, diabetes and height and remained higher in men after addition of lean mass to the model. We conclude that FN BMD is higher in Aboriginal and/or Torres Strait Islander Australians than Caucasian Australian reference ranges and these differences still remained significant in men after adjustment for lean mass. It remains to be seen whether these BMD differences translate to differences in fracture rates. Copyright © 2012 Elsevier Inc. All rights reserved.

  12. What are the legal dimensions to climate change in the Torres Strait?

    2007-01-01

    Full text: Full text: Climate change projections suggest that the Torres Strait Islands are one of the most vulnerable regions in Australia. This is due, in part, because several of the islands are only a metre or two above local mean sea level. Social and economic disadvantage further reduces the capacity to adapt to rapid environmental change, and so this problem is compounded on many of the Islands which lack adequate infrastructure, health services and employment opportunities. Consequently, considering the biophysical impacts in the socio-economic context is highly significant in order to understand - and hopefully improve - these communities' resilience to climate change. Cultural issues, not normally considered by natural scientists working on identifying climate impacts in human settlements, add increasing complexity to comprehending the full impacts of climate change in this location. Many Islanders connect the health of their land and sea country to their mental and physical wellbeing and, more broadly, their cultural integrity. In the longer term, the very existence of Ailan Kastom (Island Custom) may be threatened if projected sea level rise in combination with extreme weather events increases the frequency and/or severity of inundation incidents and necessitates relocation from the Islands. One other significant concern that has not been given appropriate consideration relates to the legal status of land (and sea) ownership. Over the last 15 years, the Torres Strait Islanders have successfully fought to obtain native title rights. Some Islanders are now concerned that these rights may disappear due to the impacts of climate change. In order to explore these issues, this paper provides: 1. a background to the climate change projections and likely direct and indirect impacts on the islands; and 2. a discussion of the legal dimension of the potential for climate change to impact on the native title rights of Torres Strait Islanders. We use the Torres

    This special issue of Continental Shelf Research contains 20 papers giving research results produced as part of Australia's Torres Strait Co-operative Research Centre (CRC) Program, which was funded over a three-year period during 2003-2006. Marine biophysical, fisheries, socioeconomic-cultural and extension research in the Torres Strait region of northeastern Australia was carried out to meet three aims: 1) support the sustainable development of marine resources and minimize impacts of resource use in Torres Strait; 2) enhance the conservation of the marine environment and the social, cultural and economic well being of all stakeholders, particularly the Torres Strait peoples; and 3) contribute to effective policy formulation and management decision making. Subjects covered, including commercial and traditional fisheries management, impacts of anthropogenic sediment inputs on seagrass meadows and communication of science results to local communities, have broad applications to other similar environments.

    Full Text Available Background: Tobacco smoking is the leading contributor to the burden of disease among Aboriginal and Torres Strait Islander Australians. Reducing tobacco use in this population is a public health priority. Precise monitoring of smoking prevalence trends is central to implementation and evaluation of effective tobacco control. The way in which trends are reported influences understanding of the extent of progress, with potential implications for policy. Our objective was to quantify absolute changes in Aboriginal and Torres Strait Islander adult (≥18 years old daily tobacco smoking prevalence from 2004 to 2015, including comparisons with the total Australian population, and by age, sex and remoteness. Methods: We analysed multiple nationally representative surveys of the Aboriginal and Torres Strait Islander, and total Australian, population conducted from 2004 to 2015. Aligned with strength-based approaches, we applied a progress frame, focusing on absolute differences in smoking prevalence within the Aboriginal and Torres Strait Islander population. Results: The prevalence of current daily smoking among Aboriginal and Torres Strait Islander adults nationally was 50.0% (95% confidence interval [CI] 47.9, 52.2 in 2004–05 and 41.4% (95% CI 39.1, 43.6 in 2014–15, representing an absolute prevalence decrease of 8.6 percentage points (95% CI 5.5, 11.8 over the past decade. This is comparable with the 6.8 percentage point (95% CI 5.6, 7.9 decrease in smoking prevalence in the total Australian population over the same period, from 21.3% in 2004–05 (95% CI 20.5, 22.0 to 14.5% in 2014–15 (95% CI 13.6, 15.4.

    The shallow magmatic Torres del Paine Intrusive Complex (TPIC) belongs to a series of sub-volcanic and plutonic igneous bodies in Southern Chile and Argentina. This trench-parallel belt is located in a transitional position between the Patagonia Batholith in the West, and the alkaline Cenozoic plateau lavas in the East. While volumetrically small amounts of magmatism started around 28 my ago in the Torres del Paine area, and a second period occurred between 17-16 Ma, it peaked with the TPIC 12.59-12.43 Ma ago. The spectacular cliffs of the Torres del Paine National park provide a unique opportunity to study the evolution of a very shallow magma chamber and the interaction with its host rocks. Intrusion depth can be estimated based on contact metamorphic assemblages and granite solidus thermobarometry to 750±250 bars, corresponding to an intrusion depth of ca. 3km, ca. 500m above the base of the intrusion. Hornblende thermobarometry in mafic rocks agrees well with these estimates (Leuthold et al., 2014). The TPIC is composed of a granitic laccolith emplaced over 90ka (Michel et al., 2008) in 3 major, several 100m thick sheets, forming an overall thickness of nearly 2 km. Contacts are sharp between sheets, with the oldest sheet on the top and the youngest on the bottom (Michel et al., 2008). The granitic laccolith is under-plated by a ca. 400m thick mafic laccolith, built up over ca. 50ka (Leuthold et al. 2012), constructed from the bottom up. Granitic and mafic sheets are themselves composed of multiple metric to decametric pulses, mostly with ductile contacts between them, resulting in outcrop patterns resembling braided stream sediments. The contact of the TPIC with the Cretaceous flysch sediments document intrusion mechanism. Pre-existing sub-horizontal fold axes are rotated in the roof of the TPIC, clearly demonstrating ballooning of the roof; no ballooning was observed in the footwall of the intrusion. Extension during ballooning of the roof is indicated by

    2016-12-01

    Full Text Available Background: Routine eye and vision assessments are vital for the detection and subsequent management of vision loss, which is particularly important for Aboriginal and Torres Strait Islander people, who face higher rates of vision loss than other Australians. In order to guide improvements, this paper will describe patterns, variations and gaps in these eye and vision assessments for Aboriginal and Torres Strait Islander people. Methods: Clinical audits from 124 primary health care centres (sample size 15,175 from five Australian States and Territories were conducted during 2005-2012. Main outcome measure was adherence to current guidelines for delivery of eye and vision assessments to adults with diabetes, those without a diagnosed major chronic disease and children attending primary health care centres. Results: Overall delivery of recommended eye and vision assessments varied widely between health centres. Of the adults with diabetes, 45% had a visual acuity assessment recorded within the previous 12 months (health centre range 0-88%, and 33% had a retinal examination recorded (health centre range 0-73%. Of the adults with no diagnosed major chronic disease, 31% had a visual acuity assessment recorded within the previous two years (health centre range 0-30%, and 13% had received an examination for trichiasis (health centre range 0-40%. In children, 49% had a record of a vision assessment (health centre range 0-97%, and 25% had a record of an examination for trachoma within the previous 12 months (health centre range 0-63%. Conclusions: There was considerable range, and variation in the recorded delivery of scheduled eye and vision assessments across health centres. Sharing the successful strategies of the better-performing health centres to support focused improvements in key areas of need may increase overall rates of eye examinations – important for the timely detection, referral and treatment of eye conditions affecting Aboriginal and

    Introduction Although Aboriginal and Torres Strait Islander children in Australia have higher risk of burns compared with non-Aboriginal children, their access to burn care, particularly postdischarge care, is poorly understood, including the impact of care on functional outcomes. The objective of this study is to describe the burden of burns, access to care and functional outcomes in Aboriginal and Torres Strait Islander children in Australia, and develop appropriate models of care. Methods and analysis All Aboriginal and Torres Strait Islander children aged under 16 years of age (and their families) presenting with a burn to a tertiary paediatric burn unit in 4 Australian States (New South Wales (NSW), Queensland, Northern Territory (NT), South Australia (SA)) will be invited to participate. Participants and carers will complete a baseline questionnaire; follow-ups will be completed at 3, 6, 12 and 24 months. Data collected will include sociodemographic information; out of pocket costs; functional outcome; and measures of pain, itch and scarring. Health-related quality of life will be measured using the PedsQL, and impact of injury using the family impact scale. Clinical data and treatment will also be recorded. Around 225 participants will be recruited allowing complete data on around 130 children.

    Full Text Available The control tower consists of a low building and the actual tower. The 2,400 m2 surface space of the concrete base building is occupied by administrative offices, training facilities, shops and reception area. The structural system of the 60 m high tower is made up of 4 service cores, completed by a cabin and a control equipment level. The service cores are hollow modular units, equally of concrete, which house the elevator, stairs, power and communication cables. The cabin that crowns the tower is an 11-sided polygon. Immediately below it is the equipment level, formed by four quadrants the configuration of which guarantees 360 degree visibility. The control tower is the focal point and nerve centre of the activities at the airport.Está formada por un cuerpo bajo y la torre propiamente dicha. La base, realizada de hormigón, distribuye, en sus 2.400 m2 de superficie: oficinas administrativas, locales de enseñanza, tiendas y una zona de recepción. La torre, de 60 m de altura, se diseñó como un sistema estructural constituido por cuatro núcleos de servicio, rematada por una cabina y una planta para los equipos de control. Los núcleos son unidades modulares huecas, también de hormigón, que albergan en su interior un ascensor, las escaleras, las instalaciones de electricidad y comunicaciones. La cabina que corona el edificio es un polígono regular de once lados. Inmediatamente debajo de ella se encuentra el nivel de equipos, formado por cuatro cuadrantes cuya configuración asegura una visibilidad de 360°. La torre es el punto focal y centro neurálgico de todas las actividades del aeropuerto.

    Full Text Available The text addresses the structural consolidation carried out on the Torre de los Secretos of Baena Castle (Cordoba, as part of the restoration works planned for the castle complex. The intervention began with a comprehensive preliminary study that made it possible to glean rigorous knowledge of the materials and traditional building methods. The structural consolidation of this fabric, a mixture of masonry and rammed earth, was performed by means of a simple timber mesh system that remained concealed once the works were completed. The works also included the repair of the walls, showing the greatest possible respect for the existing materials and conserving the original textures and shapes.

    2008-01-01

    Objectives: Indigenous people of the Torres Strait (Australia) have greater potential for cadmium exposure and renal damage than other Australians due to high cadmium in some traditional seafood and a high prevalence of Type 2 diabetes, hypertension, smoking, and obesity. This study explored associations between albuminuria and an index of cadmium exposure (urinary cadmium excretion) in the presence and absence of Type 2 diabetes. Research design and methods: Two population-based, cross-sectional studies were undertaken in the Torres Strait to obtain data on body mass index (BMI), blood pressure, chronic disease, smoking, urinary cadmium, and albumin creatinine ratio (ACR). Results: Age- and BMI-adjusted urinary cadmium levels were significantly higher (p<0.01) among people with diabetes and albuminuria (n=22, geometric mean (GM) 1.91 μg Cd/g creatinine) compared to those with diabetes and normal ACR (n=21, GM 0.74 μg Cd/g creatinine). Urinary cadmium was also strongly associated (p<0.001) with ACR among people with diabetes in regression models and remained significant after controlling for age, sex, BMI, smoking status, and hypertension (or continuous systolic and diastolic measurements). Conclusions: While the study has methodological limitations and the nature of the association is unclear, the striking dose-dependent links between markers of cadmium exposure and of Type 2 diabetic nephropathy highlight the need for further definitive research on the health effects of cadmium in the presence of diabetes

  6. Very high-power electron-beam transport in long gas cells from 10-3 to 103 Torr N2

    International Nuclear Information System (INIS)

    Sanford, T.W.L.

    1994-01-01

    Measurements and analyses show that the 13-TW, pulsed Hermes-III electron beam, with current near the Alfven limit, has two regimes of stable transport: a low-pressure window (between ∼1 and ∼100 mTorr) that is dominated by propagation in the semi-collisionless IFR (ion-focused regime), and a high-pressure window (between ∼1 and ∼100 Torr) that is dominated by propagation in the resistive CDR (collision-dominated regime). Propagation in both regimes (the IFR at early time and the CDR at later time) is observed from ∼10 to ∼100 mTorr. Below ∼1 mTorr, there is insufficient ionization to confine the beam. As the pressure increases, two-stream instabilities terminate IFR propagation earlier in time. Above 10 mTorr, this instability is sufficiently quenched by gas collisions that CDR propagation in the beam body occurs. Above ∼100 mTorr, the gas breaks down too rapidly for a significant IFR pulse to form, and for higher pressures only a single pulse in the CDR is propagated. Between ∼100 mTorr and ∼1 Torr, however, the hollowing instability and lack of magnetic confinement limit CDR propagation, and above ∼100 Torr, the resistive hose instability again degrades propagation

  7. Reversal of subtidal dune asymmetries caused by seasonally reversing wind-driven currents in Torres Strait, northeastern Australia

    Harris, Peter T.

    1991-07-01

    Large subtidal sand dunes (sandwaves) located in Adolphus Channel, Torres Strait, have been observed to reverse their asymmetric orientation between September-February. This has been attributed to a reversal in wind-driven currents, which flow westward during the SE trade season (April-November) and eastwards during the NW monsoon season [December-March: HARRIS (1989) Continental Shelf Research, 9, 981-1002]. Observations in September 1988 and February 1989 from another area of dunes in Torres Strait corroborate this asymmetry reversal pattern. The results indicate that such reversals may be common in Torres Strait and in other areas where subtidal bedforms are subject to modification by superimposed, seasonally reversing, wind-driven currents.

    Andrew F. van den Hurk

    2016-12-01

    Full Text Available The “Asian tiger mosquito”, Aedes albopictus, is highly invasive, an aggressive biter and a major arbovirus vector. It is not currently present on mainland Australia despite being intercepted on numerous occasions at international ports and infesting the Torres Strait of Australia since at least 2004. In the current paper, we describe the invasion and current status of Ae. albopictus in the Torres Strait, as well as research conducted to assess the threat of this species becoming established in arbovirus transmission cycles on the Australian mainland. Genetic analysis of the invading population demonstrated that the Indonesian region was the likely origin of the invasion and not Papua New Guinea (PNG as initially suspected. There was also intermixing between Torres Strait, PNG and Indonesian populations, indicating that the species could be re-introduced into the Torres Strait compromising any successful eradication programme. Vector competence experiments with endemic and exotic viruses revealed that Ae. albopictus from the Torres Strait are efficient alphavirus vectors, but less efficient flavivirus vectors. Ae. albopictus obtains blood meals from a range of vertebrate hosts (including humans, indicating that it could play a role in both zoonotic and human-mosquito arbovirus transmission cycles in Australia. Predictive models coupled with climate tolerance experiments suggest that a Torres Strait strain of Ae. albopictus could colonise southern Australia by overwintering in the egg stage before proliferating in the warmer months. Cohabitation experiments demonstrated that the presence of Aedes notoscriptus larvae in containers would not prevent the establishment of Ae. albopictus. Evidence from these studies, coupled with global experience suggests that we need to be prepared for the imminent invasion of Australia by Ae. albopictus by thoroughly understanding its biology and being willing to embrace emerging control technologies.

    Although Aboriginal and Torres Strait Islander children in Australia have higher risk of burns compared with non-Aboriginal children, their access to burn care, particularly postdischarge care, is poorly understood, including the impact of care on functional outcomes. The objective of this study is to describe the burden of burns, access to care and functional outcomes in Aboriginal and Torres Strait Islander children in Australia, and develop appropriate models of care. All Aboriginal and Torres Strait Islander children aged under 16 years of age (and their families) presenting with a burn to a tertiary paediatric burn unit in 4 Australian States (New South Wales (NSW), Queensland, Northern Territory (NT), South Australia (SA)) will be invited to participate. Participants and carers will complete a baseline questionnaire; follow-ups will be completed at 3, 6, 12 and 24 months. Data collected will include sociodemographic information; out of pocket costs; functional outcome; and measures of pain, itch and scarring. Health-related quality of life will be measured using the PedsQL, and impact of injury using the family impact scale. Clinical data and treatment will also be recorded. Around 225 participants will be recruited allowing complete data on around 130 children. Qualitative data collected by in-depth interviews with families, healthcare providers and policymakers will explore the impact of burn injury and outcomes on family life, needs of patients and barriers to healthcare; interviews with families will be conducted by experienced Aboriginal research staff using Indigenous methodologies. Health systems mapping will describe the provision of care. The study has been approved by ethics committees in NSW, SA, NT and Queensland. Study results will be distributed to community members by study newsletters, meetings and via the website; to policymakers and clinicians via policy fora, presentations and publication in peer-reviewed journals.

    Involvement in scientifically structured habitat monitoring is a relatively new concept to the peoples of Torres Strait. The approach we used was to focus on awareness, and to build the capacity of groups to participate using Seagrass-Watch as the vehicle to provide education and training in monitoring marine ecosystems. The project successfully delivered quality scientifically rigorous baseline information on the seasonality of seagrasses in the Torres Strait—a first for this region. Eight seagrass species were identified across the monitoring sites. Seagrass cover varied within and between years. Preliminary evidence indicated that drivers for seagrass variability were climate related. Generally, seagrass abundance increased during the north-west monsoon ( Kuki), possibly a consequence of elevated nutrients, lower tidal exposure times, less wind, and higher air temperatures. Low seagrass abundance coincided with the presence of greater winds and longer periods of exposure at low tides during the south-east trade wind season ( Sager). No seasonal patterns were apparent when frequency of disturbance from high sedimentation and human impacts was high. Seagrass-Watch has been incorporated in to the Thursday Island High School's Marine Studies Unit ensuring continuity of monitoring. The students, teachers, and other interested individuals involved in Seagrass-Watch have mastered the necessary scientific procedures to monitor seagrass meadows, and developed skills in coordinating a monitoring program and skills in mentoring younger students. This has increased the participants' self-esteem and confidence, and given them an insight into how they may participate in the future management of their sea country.

    Long term results of different surgical techniques in Hirschsprung's Disease (HD) are contradictory. There are still no long term large or multicentric reports about functional results of De la Torre technique. We have studied the mid term functional results of the patients operated on Duhamel (D) and De la Torre (dlT) pull-through procedures. We collected data from medical records and telephone interviews of the HD patients operated in our unit in the last 16 years. 38 patients were found. Ages ranged from 1.5 to 21 years. Mean age was 7.7 years. Median follow up was 5.9 years. 33 (86.8%) had rectosigmoid disease and 5 (13.2%) had long segment disease. D procedure was performed in 17 (44.7%), Soave in 1 (2.6%), Duhamel-Lester-Martin in 4 (10.5%) and dlT pull-through in 16(42%). In the last visit record, 12 (31.6%), had constipation, and fecal leaks were noted in 11 (33.3%) of the 33 patients > or = 4 years old.. 10 patients (29.4% of the > or = 4 years old group) referred encopresis along the follow-up. Patients from the D group referred higher rates of constipation than those in the dlT group (53.3% vs 20% p=0.048). dlT patients referred more frequency of leaks (46,1% vs 13,3%, p=0,05) Children with very short resections (Encopresis was similar in all groups. Both techniques show similar functional results in the mid term, although children in the D group were more prone to constipation and those in the dlT group presented more fecal leaks.

    2016-03-01

    To evaluate the impact of a meditative singing program on the health outcomes of Aboriginal and Torres Strait Islander people. The study used a prospective intervention design. The study took place in six Aboriginal and Torres Strait Islander communities and Community Controlled Health Services in Queensland, Australia. Study participants were 210 Australian Aboriginal and Torres Strait Islander adults aged 18 to 71 years, of which 108 were in a singing intervention group and 102 in a comparison group. A participative community-based community singing program involving weekly singing rehearsals was conducted over an 18-month period. Standardized measures in depression, resilience, sense of connectedness, social support, and singing related quality of life were used. The general linear model was used to compare differences pre- and postintervention on outcome variables, and structural equation modeling was used to examine the pathway of the intervention effect. Results revealed a significant reduction in the proportion of adults in the singing group classified as depressed and a concomitant significant increase in resilience levels, quality of life, sense of connectedness, and social support among this group. There were no significant changes for these variables in the comparison group. The participatory community singing approach linked to preventative health services was associated with improved health, resilience, sense of connectedness, social support, and mental health status among Aboriginal and Torres Strait Islander adults. © The Author(s) 2016.

    Objectives Review the evidence for the effectiveness of chronic condition self-management programs applied to Aboriginal and Torres Strait Islander Peoples. Methods A rapid review methodology was followed to develop an evidence summary from peer-reviewed and grey literature. Results Only seven peer-reviewed studies were identified. The evidence indicated that group programs, particularly the Stanford Program, and structured individual chronic condition self-management programs were of good quality for Aboriginal and Torres Strait Islander Peoples, although these need to be integrated into practice in order to see the greatest benefits. The Flinders Program showed promise as a standardised program with content designed specifically with and for these populations. Numerous grey literature sources were identified, many using strong participatory approaches developed locally within Aboriginal and Torres Strait Islander Peoples. However, few of these programs have been subject to rigorous evaluation. Discussion Despite the significant focus on chronic condition self-management programs to help address the burden of disease for Aboriginal and Torres Strait Islander Peoples, few studies exist that have been properly evaluated. The Closing the Gap Principles developed by the Australian Institute of Health and Welfare offer important guidance for how to proceed to maximise engagement, cultural appropriateness and ownership of program initiatives.

    2014-01-01

    Background It is estimated that the prevalence of mental illness is higher in Aboriginal and Torres Strait Islander adolescents compared to non-Aboriginal adolescents. Despite this, only a small proportion of Aboriginal youth have contact with mental health services, possibly due to factors such as remoteness, language barriers, affordability and cultural sensitivity issues. This research aimed to develop culturally appropriate guidelines for anyone who is providing first aid to an Australian Aboriginal or Torres Strait Islander adolescent who is experiencing a mental health crisis or developing a mental illness. Methods A panel of Australian Aboriginal people who are experts in Aboriginal youth mental health, participated in a Delphi study investigating how members of the public can be culturally appropriate when helping an Aboriginal or Torres Strait Islander adolescent with mental health problems. The panel varied in size across the three sequential rounds, from 37–41 participants. Panellists were presented with statements about cultural considerations and communication strategies via online questionnaires and were encouraged to suggest additional content. All statements endorsed as either Essential or Important by ≥ 90% of panel members were written into a guideline document. To assess the panel members’ satisfaction with the research method, participants were invited to provide their feedback after the final survey. Results From a total of 304 statements shown to the panel of experts, 194 statements were endorsed. The methodology was found to be useful and appropriate by the panellists. Conclusion Aboriginal and Torres Strait Islander Youth mental health experts were able to reach consensus about what the appropriate communication strategies for providing mental health first aid to an Aboriginal and Torres Strait Islander adolescent. These outcomes will help ensure that the community provides the best possible support to Aboriginal adolescents who

    To describe attitudes towards smoking in a national sample of Aboriginal and Torres Strait Islander smokers and recent quitters and assess how they are associated with quitting, and to compare these attitudes with those of smokers in the general Australian population. The Talking About The Smokes project used a quota sampling design to recruit participants from communities served by 34 Aboriginal community-controlled health services and one community in the Torres Strait. We surveyed 1392 daily smokers, 251 non-daily smokers and 78 recent quitters from April 2012 to October 2013. Personal attitudes towards smoking and quitting, wanting to quit, and attempting to quit in the past year. Aboriginal and Torres Strait Islander daily smokers were less likely than daily smokers in the general Australian population to report enjoying smoking (65% v 81%) and more likely to disagree that smoking is an important part of their life (49% v 38%); other attitudes were similar between the two groups. In the Aboriginal and Torres Strait Islander sample, non-daily smokers generally held less positive attitudes towards smoking compared with daily smokers, and ex-smokers who had quit within the past year reported positive views about quitting. Among the daily smokers, 78% reported regretting starting to smoke and 81% reported spending too much money on cigarettes, both of which were positively associated with wanting and attempting to quit; 32% perceived smoking to be an important part of their life, which was negatively associated with both quit outcomes; and 83% agreed that smoking calms them down when stressed, which was not associated with the quitting outcomes. Aboriginal and Torres Strait Islander smokers were less likely than those in the general population to report positive reasons to smoke and held similar views about the negative aspects, suggesting that factors other than personal attitudes may be responsible for the high continuing smoking rate in this population.

    2007-11-01

    Full Text Available Abstract Aboriginal and Torres Strait Islander Australians experience widespread socioeconomic disadvantage and health inequality. In an attempt to make Indigenous health research more culturally-appropriate, Aboriginal and Torres Strait Islander Australians have called for more attention to the concept of emotional and social wellbeing (ESWB. Although it has been widely recognised that ESWB is of crucial importance to the health of Aboriginal and Torres Strait Islander peoples, there is little consensus on how to measure in Indigenous populations, hampering efforts to better understand and improve the psychosocial determinants of health. This paper explores the policy and political context to this situation, and suggests ways to move forward. The second part of the paper explores how scales can be evaluated in a health research setting, including assessments of endorsement, discrimination, internal and external reliability. We then evaluate the use of a measure of stressful life events, the Negative Life Events Scale (NLES, in two samples of Aboriginal people living in remote communities in the Northern Territory of Australia. We argue that the Negative Life Events Scale is a promising assessment of psychosocial wellbeing in Aboriginal and Torres Strait Islander populations. Evaluation of the scale and its performance in other samples of Aboriginal and Torres Strait Islander populations is imperative if we hope to develop better, rather than more, scales for measuring ESWB among Indigenous Australians. Only then will it be possible to establish standardized methods of measuring ESWB and develop a body of comparable literature that can guide both a better understanding of ESWB, and evaluation of interventions designed to improve the psychosocial health of Indigenous populations and decrease health inequalities.

    The lack of a common description makes measuring the concept of quality of life (QoL) a challenge. Whether QoL incorporates broader social features or is attributed to health conditions, the diverse range of descriptions applied by various disciplines has resulted in a concept that is multidimensional and vague. The variety of theoretical conceptualisations of QoL confounds and confuses even the most astute. Measuring QoL in Aboriginal and Torres Strait Islander populations is even more challenging. Instruments commonly developed and used to measure QoL are often derived from research methodologies shaped by Western cultural perspectives. Often they are simply translated for use among culturally and linguistically diverse Aboriginal and Torres Strait Islander peoples. This has implications for Aboriginal and Torres Strait Islander populations whose perceptions of health are derived from within their specific cultures, value systems and ways of knowing and being. Interconnections and relationships between themselves, their communities, their environment and the natural and spiritual worlds are complex. The way in which their QoL is currently measured indicates that very little attention is given to the diversity of Aboriginal and Torres Strait Islander peoples' beliefs or the ways in which those beliefs shape or give structure and meaning to their health and their lives. The use of Indigenist or Indigenous methodologies in defining what Aboriginal and Torres Strait Islander peoples believe gives quality to their lives is imperative. These methodologies have the potential to increase the congruency between their perceptions of QoL and instruments to measure it.

    Full Text Available Un primer acercamiento a las reflexiones de Rem Koolhaas en torno a la tipología de torre introduce al rascacielos neoyorquino como la alegoría del “automonumen­to”: una construcción en esencia destinada a reafirmar su sola presencia y que se distingue del resto por medio de su estatura, que la monumentaliza. La torre de Babel, símbolo inquebrantable de la leyenda de la construcción en altura, escenifi­ca una historia de construcción y destrucción que está vinculada ineludiblemente al pensamiento crítico de Rem Koolhaas en torno a la torre como tipología desa­creditada. Un recorrido por las distintas “Babel” que Rem Koolhaas cataloga en el glosario de términos incluido en el texto SMLXL construye un discurso en torno a la destrucción de la torre bíblica y la construcción de la nueva Babel koolhaasiana que inicia su recorrido con el rascacielos para acabar reclamando un nuevo estado de monumentalidad: la ausencia en su estado más puro representado por el muro, el máximo ejemplo de ausencia como la forma más elevada de presencia monu­mental. Una mirada crítica que comienza con la torre metropolitana como la nueva Babel para finalizar con el muro como el monumento al vacío

  7. Aboriginal and Torres Strait Islander Worldviews and Cultural Safety Transforming Sexual Assault Service Provision for Children and Young People

    Full Text Available Child Sexual Assault (CSA in Aboriginal and Torres Strait Islander communities is a complex issue that cannot be understood in isolation from the ongoing impacts of colonial invasion, genocide, assimilation, institutionalised racism and severe socio-economic deprivation. Service responses to CSA are often experienced as racist, culturally, financially and/or geographically inaccessible. A two-day forum, National Yarn Up: Sharing the Wisdoms and Challenges of Young People and Sexual Abuse, was convened by sexual assault services to identify the main practice and policy concerns regarding working with Aboriginal and Torres Strait Islander children and young people (C&YP, families and communities in the context of CSA. The forum also aimed to explore how services can become more accountable and better engaged with the communities they are designed to support. The forum was attended by eighty invited Aboriginal and Torres Strait Islander and non-Aboriginal youth sexual assault managers and workers representing both “victim” and “those who sexually harm others” services. In keeping with Aboriginal Community-Based Research methods forum participants largely directed discussions and contributed to the analysis of key themes and recommendations reported in this article. The need for sexual assault services to prioritise cultural safety by meaningfully integrating Aboriginal and Torres Strait Islander Worldviews emerged as a key recommendation. It was also identified that collaboration between “victims” and “those who sexually harm” services are essential given Aboriginal and Torres Strait Islander C&YP who sexually harm others may have also been victims of sexual assault or physical violence and intergenerational trauma. By working with the whole family and community, a collaborative approach is more likely than the current service model to develop cultural safety and thus increase the accessibility of sexual assault services.

    Hypertension and other chronic disease risks are common among Aboriginal and Torres Strait Islander adults but there is little evidence regarding the epidemiology of these risk factors during adolescence. This study examines the prevalence of pre-hypertension, hypertension and other cardiovascular risk factors in Aboriginal and Torres Strait Islander people aged 15-24 years living in remote Indigenous communities in north Queensland. In so doing, it aims to better inform the approach to cardiovascular disease in this population. This is a descriptive study that retrospectively examines health service data from a program of community screening, the Young Persons Check (YPC). Participants were 1,883 Aboriginal and Torres Strait Islander people aged 15-24 years who attended for a YPC in 11 remote communities in north Queensland between March 2009 and April 2011. Overall, the prevalence of pre-hypertension was 34.0%; stage I hypertension was 17.7% and stage II hypertension was 3.3%. The prevalence of elevated waist circumference was 47.6%, overweight or obesity 45.9%, elevated triglycerides 18.3%, decreased HDL 54.8% and proteinuria 24.3%. The prevalence of hypertension (stage I or II) among Torres Strait Islander males was 34.1%, Aboriginal males 26.9%, Torres Strait Islander females 12.6% and Aboriginal females 13.0%. Hypertension was associated with sex (males) (OR= 4.37, p<0.000), overweight (OR=2.46, p<0.000), obesity (OR=4.59, p<0.000) and elevated triglycerides (OR=2.38, p<0.000). Pre-hypertension, hypertension and other cardiovascular risk in this population is highly prevalent. Hypertension was particularly prevalent among male participants. The results reiterate the importance of early life experience in cardiovascular disease prevention. © 2015 The Authors.

    It is estimated that the prevalence of mental illness is higher in Aboriginal and Torres Strait Islander adolescents compared to non-Aboriginal adolescents. Despite this, only a small proportion of Aboriginal youth have contact with mental health services, possibly due to factors such as remoteness, language barriers, affordability and cultural sensitivity issues. This research aimed to develop culturally appropriate guidelines for anyone who is providing first aid to an Australian Aboriginal or Torres Strait Islander adolescent who is experiencing a mental health crisis or developing a mental illness. A panel of Australian Aboriginal people who are experts in Aboriginal youth mental health, participated in a Delphi study investigating how members of the public can be culturally appropriate when helping an Aboriginal or Torres Strait Islander adolescent with mental health problems. The panel varied in size across the three sequential rounds, from 37-41 participants. Panellists were presented with statements about cultural considerations and communication strategies via online questionnaires and were encouraged to suggest additional content. All statements endorsed as either Essential or Important by ≥ 90% of panel members were written into a guideline document. To assess the panel members' satisfaction with the research method, participants were invited to provide their feedback after the final survey. From a total of 304 statements shown to the panel of experts, 194 statements were endorsed. The methodology was found to be useful and appropriate by the panellists. Aboriginal and Torres Strait Islander Youth mental health experts were able to reach consensus about what the appropriate communication strategies for providing mental health first aid to an Aboriginal and Torres Strait Islander adolescent. These outcomes will help ensure that the community provides the best possible support to Aboriginal adolescents who are developing mental illnesses or are in a

    The 12 Ma old Torres del Paine laccolith (TPL) is part of a chain of isolated Miocene plutons and subvolcanic rocks which intruded the foothills of the southern Andes of Chile and Argentina (Halpern, 1973; Michael, 1984). The 12x12 km big laccolith, an I-type granite, intruded mudstones, sandstones, carbonates and conglomerates of the Cretaceous Cerro Torre and Punta Barrosa formation (Wilson, 1991) creating a well defined, but small contact aureole of 200-400m width. The TPL contains abundant textural evidence of fluid exsolution and eutectic crystallisation. It hence represents a good example for the transport of large quantities of magmatic aqueous fluids to the uppermost level of the crust. The pluton is well exposed and its rugged topography allows the investigation of the roof, the lateral rims and the base of the intrusion. Field and textural observations, phase petrological constraints, oxygen isotope and fluid inclusion data are used to unravel mechanism and patterns of fluid and heat transport in the intrusion and the contact aureole. The Torres del Paine Intrusives form a calcalkaline suite, ranging from gabbros through diorites to leucogranites. The intrusive body has the general shape of a laccolith (Skarmeta and Castelli, 1997). Gabbroic and dioritic rocks are only exposed at the lower levels. Granites are clearly predominant - the main body of the laccolith is composed of a fine to medium grained biotite-orthoclase granite. The TPL is remarkable for its abundance of miarolitic cavities. Locally, at the margins of the pluton, a microgranitic phase is found with up to 15% of cavities. While some miaroles are isolated, others are interconnected, forming tube-like structures. Open miaroles contain euhedral crystals of quartz and feldspar. Other important phases are biotite, tourmaline, fayalite and late chlorite and carbonate. Individual crystals are typically between < 1cm up to a few cm in length. Some miaroles are completely filled with coarse quartz

    Geothermal heat is a viable source of energy and its environmental impact in terms of CO2 emissions is significantly lower than conventional fossil fuels. However, nowadays its utilization is inconsistent with the enormous amount of energy available underneath the surface of the earth. This is mainly due to the uncertainties associated with it, as for example the lack of appropriate computational tools, necessary to perform effective analyses. The aim of the present study is to build an accurate 3D numerical model, to simulate the exploitation process of the deep geothermal reservoir of Castel Giorgio - Torre Alfina (central Italy), and to compare results and performances of parallel simulations performed with TOUGH2 (Pruess et al. 1999), FEFLOW (Diersch 2014) and the open source software OpenGeoSys (Kolditz et al. 2012). Detailed geological, structural and hydrogeological data, available for the selected area since early 70s, show that Castel Giorgio - Torre Alfina is a potential geothermal reservoir with high thermal characteristics (120 ° C - 150 ° C) and fluids such as pressurized water and gas, mainly CO2, hosted in a carbonate formation. Our two steps simulations firstly recreate the undisturbed natural state of the considered system and then perform the predictive analysis of the industrial exploitation process. The three adopted software showed a strong numerical simulations accuracy, which has been verified by comparing the simulated and measured temperature and pressure values of the geothermal wells in the area. The results of our simulations have demonstrated the sustainability of the investigated geothermal field for the development of a 5 MW pilot plant with total fluids reinjection in the same original formation. From the thermal point of view, a very efficient buoyant circulation inside the geothermal system has been observed, thus allowing the reservoir to support the hypothesis of a 50 years production time with a flow rate of 1050 t

    Full Text Available Abstract Background Aboriginal and Torres Strait Islander people with chronic illness confront multiple challenges that contribute to their poor health outcomes, and to the health disparities that exist in Australian society. This study aimed to identify barriers and facilitators to care and support for Aboriginal and Torres Strait Islander people with chronic illness. Methods Face-to-face in-depth interviews were conducted with Aboriginal and Torres Strait Islander people with diabetes, chronic heart failure or chronic obstructive pulmonary disease (n-16 and family carers (n = 3. Interviews were transcribed verbatim and the transcripts were analysed using content analysis. Recurrent themes were identified and these were used to inform the key findings of the study. Results Participants reported both negative and positive influences that affected their health and well-being. Among the negative influences, they identified poor access to culturally appropriate health services, dislocation from cultural support systems, exposure to racism, poor communication with health care professionals and economic hardship. As a counter to these, participants pointed to cultural and traditional knowledge as well as insights from their own experiences. Participants said that while they often felt overwhelmed and confused by the burden of chronic illness, they drew strength from being part of an Aboriginal community, having regular and ongoing access to primary health care, and being well-connected to a supportive family network. Within this context, elders played an important role in increasing people’s awareness of the impact of chronic illness on people and communities. Conclusions Our study indicated that non-Indigenous health services struggled to meet the needs of Aboriginal and Torres Strait Islander people with chronic illness. To address their complex needs, health services could gain considerably by recognising that Aboriginal and Torres Strait

    Objectives The aim of the study was to assess the utility of national Aboriginal survey data in a regional geospatial analysis of daily smoking prevalence for Aboriginal and Torres Strait Islander Australians and discuss the appropriateness of this analysis for policy and program impact assessment. Methods Data from the last two Australian Bureau of Statistics (ABS) national surveys of Aboriginal and Torres Strait Islander people, the National Aboriginal and Torres Strait Islander Social Survey 2014-15 (n=7022 adults) and the National Aboriginal and Torres Strait Islander Health Survey 2012-13 (n=10896 adults), were used to map the prevalence of smoking by Indigenous regions. Results Daily smoking prevalence in 2014-15 at Indigenous regions ranges from 27.1% (95%CI 18.9-35.3) in the Toowoomba region in Queensland to 68.0% (95%CI 58.1-77.9) in the Katherine region in the Northern Territory. The confidence intervals are wide and there is no significant difference in daily smoking prevalence between the two time periods for any region. Conclusion There are significant limitations with analysing national survey data at finer geographical scales. Given the national program for Indigenous tobacco control is a regional model, evaluation requires finer geographical analysis of smoking prevalence to inform public health progress, policy and program effects. Options to improve the data currently collected include increasing national survey sample sizes, implementing a smoking status question in census surveys, investing in current cohort studies focused on this population or implementing localised surveys. What is known about the topic? The last geospatial analysis of Aboriginal and Torres Strait Islander smoking prevalence was undertaken in 1997. Current national survey data have not been analysed geospatially. What does this paper add? This paper provides new insights into the use of national survey data for understanding regional patterns and prevalence levels of smoking

    Full Text Available Muir-Torre syndrome (MTS is a rare genodermatosis, diagnosed by the presence of sebaceous neoplasms along with an internal malignancy, most commonly colorectal carcinomas. MTS is most commonly caused by microsatellite instabilities of the hMLH1 and hMSH2 mismatch repair genes, and is rarely caused by mutations of the hMSH6 gene. We describe the case of a 56-year-old male who presented with an enlarging mass on his back as well as hematochezia. The back mass was excised, and pathology confirmed microsatellite instability in MSH2 and MSH6. Abdominal CT and colonoscopy confirmed the presence of synchronous masses in the cecum, ascending colon, and the transverse colon. He refused any further workup or treatment, only to return 8 months later complaining of hematochezia and discomfort due to an enlarging mass protruding from the rectum. After consenting to surgical intervention, he agreed to outpatient chemotherapy treatment. The presence of sebaceous neoplasms should raise suspicion for the possibility of an associated internal malignancy.

    Suicide rates among Indigenous Australian children are higher than for other Australian children. The current study aimed to identify factors associated with Indigenous child suicide when compared to other Australian children. Using the Queensland Suicide Register, suicides in Indigenous children (10-14 years) and other Australian children in the same age band were compared. Between 2000 and 2010, 45 child suicides were recorded: 21 of Indigenous children and 24 of other Australian children. This corresponded to a suicide rate of 10.15 suicides per 100,000 for Indigenous children - 12.63 times higher than the suicide rate for other Australian children (0.80 per 100,000). Hanging was the predominant method used by all children. Indigenous children were significantly more likely to suicide outside the home, to be living outside the parental home at time of death, and be living in remote or very remote areas. Indigenous children were found to consume alcohol more frequently before suicide, compared to other Australian children. Current and past treatments of psychiatric disorders were significantly less common among Indigenous children compared to other Australian children. Western conceptualisation of mental illness may not adequately embody Indigenous people's holistic perspective regarding mental health. Further development of culturally appropriate suicide prevention activities for Aboriginal and Torres Strait Islander children is required. © 2014 Public Health Association of Australia.

    Full Text Available Abstract Background Obesity and related cardiovascular and metabolic conditions are well recognized problems for Australian Aboriginal and Torres Strait Islander peoples. However, there is a dearth of research on relevant eating disorders (EDs such as binge eating disorder in these groups. Methods Data were obtained from interviews of 3047 (in 2005 and 3034 (in 2008 adults who were participants in a randomly selected South Australian household survey of individuals' age > 15 years. The interviewed comprised a general health survey in which ED questions were embedded. Data were weighted according to national census results and comprised key features of ED symptoms. Results In 2005 there were 94 (85 weighted First Australian respondents, and in 2008 65 (70 weighted. Controlling for secular differences, in 2005 rates of objective binge eating and levels of weight and shape influence on self-evaluation were significantly higher in indigenous compared to non-indigenous participants, but no significant differences were found in ED features in 2008. Conclusions Whilst results on small numbers must be interpreted with caution, the main finding was consistent over the two samples. For First Australians ED symptoms are at least as frequent as for non-indigenous Australians.

    Final transport schemes for HIF are examined, with emphasis on transport for p>10 -3 Torr and Z>1 since this should simplify the reactor design and reduce the length of the accelerator. Specifically the question of charge neutralization is addressed. We find (1) the fractional neutralization f needed scales as f/sub i/ = (1-Z -2 ) which means f/sub i/>0.89 is needed for Z>3; (2) axially-trapped electrons limit the net beam potential to ephi/sub min/ = α(1/2 m/sub e/v/sub i/ 2 ) with 1≤αapprox. <4; (3) radially-expelled plasma ions increase f/sub i/ especially near the pellet; (4) radially-oscillating plasma electrons have and adiabatic limit of f/sub i/≅0.5; and (5) as f/sub i/ approaches unity, plasma particle trajectories may involve drift motions along and radially away from the ion beam. Also, criteria are given for the maximum Z/A allowed for transporting very large currents. For the HIF parameters used, it appears that neutralization will probably be adequte for Zapprox. <3

  1. Healthy imaginations: a social history of the epidemiology of Aboriginal and Torres Strait Islander health.

    2001-01-01

    It is difficult to imagine Aboriginal and Torres Strait Islander health without the powerful descriptors of epidemiology. The statistical imagery of numerical tables, pie charts, and bar graphs have become a key element in the public presentation of Indigenous public health issues. Such quantitative measurements of health draw on the authority of neutral, objective science and are thus rarely questioned in terms of their social meaning. This paper traces the history of this imagery through the 20th century, providing a social account of epidemiological description. Historical notions such as social Darwinism, assimilation, and dangerous other are all seen to be woven into the epidemiological text. The enormous rise in the epidemiological description of Indigenous health problems in recent years needs to be analyzed as a social phenomenon and, in particular, as an aspect of emerging forms of governmentality. Finally, it is argued that such analyses are needed in order to promote an anthropology of epidemiology and to avoid limiting medical anthropology to applications within epidemiology.

    2017-10-01

    Full Text Available Smoking is the leading contributor to the burden of disease among Aboriginal and Torres Strait Islander Australians, and there is considerable potential for change. Understanding the epidemic stage may provide insight into probable trends in smoking-attributable mortality, and inform program and policy development. Tobacco use among Aboriginal and Torres Strait Islander Australians has declined substantially, accompanied by declining tobacco-related cardiovascular mortality. Based on the available evidence, we expect tobacco-related cancer mortality to remain high, but peak within the next decade; however, there is a critical need for improved evidence to make an accurate assessment. The continuation and expansion of comprehensive tobacco reduction measures is expected to further decrease tobacco use. Health gains will be observed over both the short and long term.

    Otitis media is a common, generally self-limiting childhood illness that can progress to severe disease and have lifelong sequelae, including hearing loss and developmental delays. Severe disease is disproportionately prevalent among Aboriginal and Torres Strait Islander children. Primary health care is at the frontline of appropriate prevention and treatment. Continuous quality improvement in the prevention and management of important causes of morbidity in client populations is accepted best practice in primary health care and now a requirement of Australian Government funding to services providing care for Aboriginal and Torres Strait Islander children. To date, there have been no indicators for continuous quality improvement in the prevention and management of otitis media and its sequelae in primary health care. Through an expert group consensus process, seven evidence-based indicators, potentially extractable from electronic health records, have been developed. The development process and indicators are described.

This paper provides a critical analysis of project outcomes and identifies criteria that may form a suitable framework for the assessment of proposals for sexual health promotion using performing arts-based approaches in Aboriginal and Torres Strait Islander settings. A case study method was used. The first phase of analysis assessed whether project objectives were met using data collected during project planning and implementation. The second phase used these findings, augmented by interviews with key personnel, to respond to the question 'How could this be done better?'. The Project required significant human and organisational implementation support. The project was successful in facilitating event-specific community mobilisation. It raised awareness of sexual health disadvantage and engaged effectively with the target group. It laid important groundwork to progress school-based and community mechanisms to address regional youth disadvantage. Against these benefits are issues of opportunity cost and the need for ongoing resources to capitalise on the opportunities created. With substantial support and planning, such approaches can play an important role in engaging young people and bridging the gap between clinical interventions and improvements in health deriving from community-driven strategies. SO WHAT? This paper contributes to existing literature by identifying key elements of an effective approach to using performing arts in sexual health promotion in Aboriginal and Torres Strait Islander settings. It also provides guidance when consideration is being given to investment in resource-intensive health promotion initiatives.

    HISTRAP, Heavy Ion Storage Ring for Atomic Physics, is a proposed synchrotron/cooler/storage ring accelerator optimized for advanced atomic physics research. The ring has a circumference of 46.8 m, a bore diameter of about 15 cm, and requires a vacuum of 10 -12 Torr in order to decelerate highly-charged very-heavy ions down to low energies. To be able to test components and procedures to achieve this pressure, a test stand approximately modeling one-sixteenth of the ring vacuum chamber has been built. The 3.5-m-long test stand has been fabricated from 10-cm-diameter components, with 316LN stainless steel flanges. Prior to assembly, these components were vacuum fired at 950/degree/C at a pressure of 10 -4 Torr. The test stand is bakeable in situ at 300/degree/C. Pumping is achieved with two 750-L/s titanium sublimator pumps and one 60-L/s ion pump. Pressure is measured with two extractor ion gauges and a 10 -14 PP RGA. The roughing for the test stand consists of cryosorption pumps followed by a cryopump. A pressure of 4 x 10 -12 Torr has been achieved. 7 refs., 5 figs

    Full Text Available The building —which reaches 106 m in height over Street level— is located on a city lot in the isthmus which geographically defines the city and is made up by two well differentiated bodies: a a 5-storey block of offices and business premises, which covers the lot from dividing wall to dividing wall; b a tower of apartments, with 24 floors and 3 apartments per floor. It also has two basement floors for parking and a ground floor for businesses. It is a singular construction for several reasons, among which emphasis must be given to its original structure a pioneer in Spain, as well as to the arrangement of the apartments —all facing the outside— and the exterior treatment with prefabricated pieces of white concrete.El edificio —que alcanza los 106 m de altura sobre la rasante de la calle— está situado en un solar urbano, en el istmo que define geográficamente la ciudad, y se c o m p o n e de dos cuerpos bien diferenciados: a Bloque de oficinas y locales comerciales, de cinco plantas, que cubre las medianerías del solar. b Torre de viviendas, con 24 alturas y tres viviendas por planta. Dispone además de dos sótanos de garaje y una planta baja destinada a locales. Se trata de una construcción singular, por varias razones, entre las que hay que destacar su estructura original y pionera en España, si bien son dignas de mención, igualmente, la distribución de las viviendas —todas exteriores— y el tratamiento exterior, a base de piezas prefabricadas de hormigón blanco.

    Full Text Available Muir-Torre syndrome (MTS is a rare autosomal dominant genodermatosis characterized by the occurrence of sebaceous gland neoplasms and/or keratoacanthomas associated with visceral malignancies. It is considered as a subtype of hereditary nonpolyposis colorectal cancer syndrome. Characteristic sebaceous gland neoplasms include sebaceous adenoma, sebaceous carcinoma, sebaceoma, and keratoacanthoma with sebaceous differentiation. The most common visceral malignancies are colorectal and genitourinary tumors. CASE: A 47year-old male patient admitted to our clinic complaining of two lesions on the nose. Dermatological examination revealed a plaque in 1 cm diameter consisting of bright yellowish-white coloured papules with slightly umblicated appearance and telangiectasias on the left site of the nose and had a dome shaped papule in 3 mm diameter with hyperkeratotic plug on the tip of the nose. He had personal history of partial colon resection because of colon cancer and familial Lynch 2 syndrome. On dermoscopic examination of sebaceous adenoma, a few yellow comedo-like globules and branching arborizing vessels were detected. Reflectance confocal microscopy (RCM revealed a good histopathologic correlation. Sebaceous lobules were composed by clusters of ovoid cells with hyporefractile dark nuclei and bright, hyperrefractile glistening cytoplasm. Numerous roundish to ovoid dark spaces corresponding to sebaceous ducts were detected. The diagnosis of MTS was established based on the personal and family history, dermoscopic, RCM and histopathologic findings. CONCLUSIONS: MTS evaluation is required in patients with biopsy-proven sebaceous adenoma. Early diagnosis may be lifesaving in patients with MTS. A better characterization of RCM features of sebaceous tumors will allow early diagnosis of the patients with MTS.

    Full Text Available The Castel Giorgio-Torre Alfina (CG-TA, central Italy is a geothermal reservoir whose fluids are hosted in a carbonate formation at temperatures ranging between 120°C and 210°C. Data from deep wells suggest the existence of convective flow. We present the 3D numerical model of the CG-TA to simulate the undisturbed natural geothermal field and investigate the impacts of the exploitation process. The open source finite-element code OpenGeoSys is applied to solve the coupled systems of partial differential equations. The commercial software FEFLOW® is also used as additional numerical constraint. Calculated pressure and temperature have been calibrated against data from geothermal wells. The flow field displays multicellular convective patterns that cover the entire geothermal reservoir. The resulting thermal plumes protrude vertically over 3 km at Darcy velocity of about 7⁎10-8 m/s. The analysis of the exploitation process demonstrated the sustainability of a geothermal doublet for the development of a 5 MW pilot plant. The buoyant circulation within the geothermal system allows the reservoir to sustain a 50-year production at a flow rate of 1050 t/h. The distance of 2 km, between the production and reinjection wells, is sufficient to prevent any thermal breakthrough within the estimated operational lifetime. OGS and FELFOW results are qualitatively very similar with differences in peak velocities and temperatures. The case study provides valuable guidelines for future exploitation of the CG-TA deep geothermal reservoir.

    In 2011 Bond University was looking for innovative ways to meet the professional standards and guidelines in Aboriginal and Torres Strait Islander health in its Bachelor of Medicine, Bachelor of Surgery (MBBS) curriculum. In 2012 Bond piloted a compulsory cultural immersion program for all first year students, which is now a usual part of the MBBS program. Three phases were included - establishing an Indigenous health group, determining the Aboriginal and Torres Strait Islander educational content based on the professional standards and developing nine educational sessions and resources - as well as significant administrative processes. The cultural immersion was piloted in 2012 with 92 first year medical students. Following refinements it was repeated in 2013 with 95 students and in 2014 with 94 students. A comprehensive evaluation process was undertaken that included a paper-based evaluation form using a five-point Likert scale, as well as a confidential talking circle evaluation. The response rate was 95.4% (n=271, pooled cohort). Data were entered separately into SPSS and annual reports were written to the Faculty. Descriptive statistics are reported alongside themed qualitative data. The three combined student evaluation results were extremely positive. Students (n=271) strongly agreed that the workshop was well organised (M=4.3), that the facilitators contributed very positively to their experience (M=4.3), and that they were very satisfied overall with the activity (M=4.2). They agreed that the eight overall objectives had been well met (M=3.9-4.3). The nine sessions were highly evaluated with mean ratings of between 3.9 and 4.8. The 'best thing' about the immersion identified by more than half of the students was overwhelmingly (n=140) the Storytelling session, followed by bonding with the cohort, the Torres Strait Islander session and learning more about culture. The item identified as needing most improvement was the food (n=87), followed by the

    Laser-induced breakdown spectroscopy (LIBS) is an atomic emission spectroscopy that utilizes a highly irradiated pulse laser focused on the target surface to produce plasma. We obtain spectroscopic information from the microplasma and determine the chemical composition of the sample based on its elemental and molecular emission peaks. We develop a stand-off LIBS system to analyze the effect of the remote sensing of aluminum and various geochemical reference materials at pressures below 1 torr. Using a commercial 4 inch refracting telescope, our stand-off LIBS system is configured at a distance of 7.2 m from the four United States Geological Survey (USGS) geochemical samples that include granodiorite, quartz latite, shale-cody, and diabase, which are selected for planetary exploration. Prepared samples were mixed with a paraffin binder containing only hydrogen and carbon, and were pelletized for experimental convenience. The aluminum plate sample is considered as a reference prior to using the geochemical samples in order to understand the influence of a low pressure condition on the resulting LIBS signal. A Q-switched Nd:YAG laser operating at 1064 nm and pulsed at 10 Hz with 21.7 to 48.5 mJ/pulse was used to obtain signals, which showed that the geochemical samples were successfully detected by the present stand-off detection scheme. A low pressure condition generally results in a decrease of the signal intensity, while the signal to noise ratio can vary according to the samples and elements of various types. We successfully identified the signals at below 1 torr with stand-off detection by a tightly focused light detection and by using a relatively larger aperture telescope. The stand-off LIBS detection at low pressure is promising for potential detection of the minor elements at pressures below 1 torr. - Highlights: • Stand-off LIBS signals at below 1 torr are compared to those of in-situ conditions. • Vacuum condition provides easier detection of the

    In Australia, mental health services are undergoing major systemic reform with eMental Health (eMH) embedded in proposed service models for all but those with severe mental illness. Aboriginal and Torres Strait Islander service providers have been targeted as a national priority for training and implementation of eMH into service delivery. Implementation studies on technology uptake in health workforces identify complex and interconnected variables that influence how individual practitioners integrate new technologies into their practice. To date there are only two implementation studies that focus on eMH and Aboriginal and Torres Strait Islander service providers. They suggest that the implementation of eMH in the context of Aboriginal and Torres Strait Islander populations may be different from the implementation of eMH with allied health professionals and mainstream health services. The objective of this study is to investigate how Aboriginal and Torres Strait Islander service providers in one regional area of Australia used eMH resources in their practice following an eMH training program and to determine what types of eMH resources they used. Individual semistructured qualitative interviews were conducted with a purposive sample of 16 Aboriginal and Torres Strait Islander service providers. Interviews were co-conducted by one indigenous and one non-indigenous interviewer. A sample of transcripts were coded and thematically analyzed by each interviewer and then peer reviewed. Consensus codes were then applied to all transcripts and themes identified. It was found that 9 of the 16 service providers were implementing eMH resources into their routine practice. The findings demonstrate that participants used eMH resources for supporting social inclusion, informing and educating, assessment, case planning and management, referral, responding to crises, and self and family care. They chose a variety of types of eMH resources to use with their clients, both culturally

    Full Text Available BackgroundAboriginal and Torres Strait Islander Australians have poorer cancer outcomes and experience 30% higher mortality rates compared to non-Indigenous Australians. Primary health care (PHC services are increasingly being recognized as pivotal in improving Indigenous cancer patient outcomes. It is currently unknown whether patient information systems and practices in PHC settings accurately record Indigenous and cancer status. Being able to identify Indigenous cancer patients accessing services in PHC settings is the first step in improving outcomes.MethodsAboriginal Medical Centres, mainstream (non-Indigenous specific, and government-operated centers in Queensland were contacted and data were collected by telephone during the period from 2014 to 2016. Participants were asked to (i identify the number of patients diagnosed with cancer attending the service in the previous year; (ii identify the Indigenous status of these patients and if this information was available; and (iii advise how this information was obtained.ResultsTen primary health care centers (PHCCs across Queensland participated in this study. Four centers were located in regional areas, three in remote areas and three in major cities. All participating centers reported ability to identify Indigenous cancer patients attending their service and utilizing electronic Patient Care Information Systems (PCIS to manage their records; however, not all centers were able to identify Indigenous cancer patients in this way. Indigenous cancer patients were identified by PHCCs using PCIS (n = 8, searching paper records (n = 1, and combination of PCIS and staff recall (n = 1. Six different types of PCIS were being utilized by participating centers. There was no standardized way to identify Indigenous cancer patients across centers. Health service information systems, search functions and capacities of systems, and staff skill in extracting data using PCIS varied between centers

    Low levels of serum 25-hydroxy vitamin D (25(OH)D), have been associated with development of type 2 diabetes and cardiovascular disease (CVD); however there are limited data on serum 25(OH)D in Indigenous Australians, a population at high risk for both diabetes and CVD. We aimed to assess levels of serum 25(OH)D in Aboriginal and Torres Strait Islander Australians and to explore relationships between 25(OH)D and cardio-metabolic risk factors and diabetes. 592 Aboriginal and/or Torres Strait Islander Australian participants of The eGFR (estimated glomerular filtration rate) Study, a cross-sectional analysis of a cohort study performed in 2007-2011, from urban and remote centres within communities, primary care and tertiary hospitals across Northern Territory, Far North Queensland and Western Australia. Assessment of serum 25(OH)D, cardio-metabolic risk factors (central obesity, diabetes, hypertension, history of cardiovascular disease, current smoker, low HDL-cholesterol), and diabetes (by history or HbA1c ≥6.5%) was performed. Associations were explored between 25(OH)D and outcome measures of diabetes and number of cardio-metabolic risk factors. The median (IQR) serum 25(OH)D was 60 (45-77) nmol/L, 31% had 25(OH)D 72 nmol/L, respectively) after adjusting for known cardio-metabolic risk factors. The percentage of 25(OH)D levels Aboriginal and Torres Strait Islander Australians from Northern and Central Australia. Low 25(OH)D level was associated with adverse cardio-metabolic risk profile and was independently associated with diabetes. These findings require exploration in longitudinal studies.

    Ecotourism and protected area visitation in Central and South America are largely dependent upon a relatively undisturbed quality of natural resources. However, visitation may impact vegetation, soil, water and wildlife resources, and degrade visitor facilities such as recreation sites and trails. Findings are reported from trail impact research conducted at Torres del Paine National Park in Patagonia, Chile. The frequency and magnitude of selected trail impacts and the relative effect of the amount of use, vegetation type, trail position and trail grade are investigated. Findings differed from previous studies in that amount of use was significantly related to both trail width increases and trail erosion. Management actions to minimize trail impacts are offered.

  4. The Gulf of Carpentaria heated Torres Strait and the Northern Great Barrier Reef during the 2016 mass coral bleaching event

    The 2015/16 ENSO event increased the temperature of waters surrounding northeast Australia to above 30 °C, with large patches of water reaching 32 °C, for over two months, which led to severe bleaching of corals of the Northern Great Barrier Reef (NGBR). This study provides evidence gained from remote-sensing data, oceanographic data and oceanographic modeling, that three factors caused this excessive heating, namely: 1) the shutdown of the North Queensland Coastal Current, which would otherwise have flushed and cooled the Northern Coral Sea and the NGBR through tidal mixing 2) the advection of warm (>30 °C) water from the Gulf of Carpentaria eastward through Torres Strait and then southward over the NGBR continental shelf, and 3) presumably local solar heating. The eastward flux of this warm water through Torres Strait was driven by a mean sea level difference on either side of the strait that in turn was controlled by the wind, which also generated the southward advection of this warm water onto the NGBR shelf. On the NGBR shelf, the residence time of this warm water was longer inshore than offshore, and this may explain the observed cross-shelf gradient of coral bleaching intensity. The fate of the Great Barrier Reef is thus controlled by the oceanography of surrounding seas.

    Attenuated familial adenomatous polyposis and Muir-Torre syndrome linked to compound biallelic constitutional MYH gene mutations.Peculiar dermatologic manifestations are present in several heritable gastrointestinal disorders. Muir-Torre syndrome (MTS) is a genodermatosis whose peculiar feature is the presence of sebaceous gland tumors associated with visceral malignancies. We describe one patient in whom multiple sebaceous gland tumors were associated with early onset colon and thyroid cancers and attenuated polyposis coli. Her family history was positive for colonic adenomas. She had a daughter presenting with yellow papules in the forehead region developed in the late infancy. Skin and visceral neoplasms were tested for microsatellite instability and immunohistochemical status of mismatch repair (MMR), APC and MYH proteins. The proband colon and skin tumors were microsatellite stable and showed normal expression of MMR proteins. Cytoplasmic expression of MYH protein was revealed in colonic cancer cells. Compound heterozygosity due to biallelic mutations in MYH, R168H and 379delC, was identified in the proband. The 11-year-old daughter was carrier of the monoallelic constitutional mutation 379delC in the MYH gene; in the sister, the R168H MYH gene mutation was detected. This report presents an interesting case of association between MYH-associated polyposis and sebaceous gland tumors. These findings suggest that patients with MTS phenotype that include colonic polyposis should be screened for MYH gene mutations.

    To assess the cross-cultural validity of two Kessler psychological distress scales (K-10 and K-5) by examining their measurement properties among older Aboriginal and Torres Strait Islanders and comparing them to those in non-Aboriginal individuals from NSW Australia. Self-reported questionnaire data from the 45 and Up Study for 1,631 Aboriginal and 231,774 non-Aboriginal people were used to examine the factor structure, convergent validity, internal consistency and levels of missing data of K-10 and K-5. We found excellent agreement in classification of distress of Aboriginal participants by K-10 and K-5 (weighted kappa=0.87), high internal consistency (Cronbach's alpha K-10: 0.93, K-5: 0.88), and factor structures consistent with those for the total Australian population. Convergent validity was evidenced by a strong graded relationship between the level of distress and the odds of: problems with daily activities due to emotional problems; current treatment for depression or anxiety; and poor quality of life. K-10 and K-5 scales are promising tools for measuring psychological distress among Aboriginal and Torres Strait Islanders aged 45 and over in research and clinical settings. © 2014 Public Health Association of Australia.

    1990-02-01

    An extremely high vacuum (XHV) chamber was fabricated and tested. The vacuum chamber was made of special surface finished (EX-process) aluminum alloy in oxygen and argon atmosphere. The chamber was assembled using TIG welding in an argon atmosphere and by electron beam welding. The system was evacuated with a turbo-backed 300 l/s turbomolecular pump separated from the main chamber using a right angle valve. The liquid nitrogen shroud is installed inside the main vacuum chamber. The XHV is maintained by two 300 l/s sputter ion pumps and a titanium sublimation pump with a liquid nitrogen shroud. These pumps are also made of aluminum alloys. An ultimate pressure of 3×10-13 Torr was measured with a point collector gauge with a spherical anode mounted on an Al-flange. Residual gas analysis in the order 10-13 Torr was performed by a newly developed Q-mass filter. To suppress outgassing from the quadrupole electrode, the ion source is mounted on an Al-flange separated from the quadrupole electrode.

    The paper presents the development and demonstrates the capabilities of a new laboratory-based environmental X-ray photoelectron spectroscopy system incorporating an electrostatic lens and able to acquire spectra up to 0.4 Torr. The incorporation of a two-dimensional detector provides imaging capabilities and allows the acquisition of angle-resolved data in parallel mode over an angular range of 14° without tilting the sample. The sensitivity and energy resolution of the spectrometer have been investigated by analyzing a standard Ag foil both under high vacuum (10 −8 Torr) conditions and at elevated pressures of N 2 (0.4 Torr). The possibility of acquiring angle-resolved data at different pressures has been demonstrated by analyzing a silicon/silicon dioxide (Si/SiO 2 ) sample. The collected angle-resolved spectra could be effectively used for the determination of the thickness of the native silicon oxide layer.

The TATS project is a collaboration between research institutions and Aboriginal community-controlled health services (ACCHSs) and their state and national representative bodies. It is one of the studies within the International Tobacco Control Policy Evaluation Project, enabling national and international comparisons. It includes a prospective longitudinal study of Aboriginal and Torres Strait Islander smokers and recent ex-smokers; a survey of non-smokers; repeated cross-sectional surveys of ACCHS staff; and descriptions of the tobacco policies and practices at the ACCHSs. Community members completed face-to-face surveys; staff completed surveys on paper or online. We compared potential biases and the distribution of variables common to the main community baseline sample and unweighted and weighted results of the 2008 National Aboriginal and Torres Strait Islander Social Survey (NATSISS). The baseline survey (Wave 1) was conducted between April 2012 and October 2013. 2522 Aboriginal and Torres Strait Islander people in 35 locations (the communities served by 34 ACCHSs and one community in the Torres Strait), and 645 staff in the ACCHSs. Sociodemographic and general health indicators, smoking status, number of cigarettes smoked per day and quit attempts. The main community baseline sample closely matched the distribution of the Aboriginal and Torres Strait Islander population in the weighted NATSISS by age, sex, jurisdiction and remoteness. There were inconsistent differences in some sociodemographic factors between our sample and the NATSISS: our sample had higher proportions of unemployed people, but also higher proportions who had completed Year 12 and who lived in more advantaged areas. In both surveys, similar percentages of smokers reported having attempted to quit in the past year, and daily smokers reported similar numbers of cigarettes smoked per day. The

    Full Text Available In occasione del novantesimo anniversario dalla nascita di Pio La Torre, e in sintonia con numerose celebrazioni istituzionali, la Rivista propone, all’interno di questa sezione, un documento il cui valore storico, politico e giudiziario è stato riconosciuto solo a distanza di anni. Si tratta della Relazione di minoranza datata 4 febbraio 1976, redatta dall’onorevole Pio La Torre, insieme al giudice Cesare Terranova e sottoscritta dai deputati Benedetti, Malagugini, e dai senatori Adamoli, Chiaromonte, Lugnano e Maffioletti alla fine della VI Legislatura. La Relazione, qui integralmente ripubblicata - fatta esclusione per gli allegati -, si pone in netto contrasto con l’impianto della Relazione di maggioranza della Commissione parlamentare di inchiesta sul fenomeno della mafia in Sicilia, presieduta dal senatore Luigi Carraro. La valutazione fortemente critica proposta dai firmatari muove dall’accusa di aver omesso nella Relazione generale, il tema centrale per la comprensione del fenomeno mafioso ovvero il rapporto di compenetrazione tra il sistema di potere mafioso e l’apparato statuale-politico. La Relazione, come può intuire il lettore, contiene già le premesse della proposta di legge di Pio La Torre sul reato di associazione mafiosa, che sarà approvata il 13 settembre 1982 e diventerà come Legge “Rognoni- La Torre” una pietra miliare della normativa antimafia italiana.    For the ninetieth anniversary of the birth of Pio La Torre, the Review proposes in this section the minority report dated 4 February 1976. The report was drawn up by the deputy La Torre, together with the judge Terranova and it was endorsed by deputies Benedetti, Malagugini and by senators Adamoli, Chiaromonte, Lugnano e Maffioletti by the end of the legislature. The Review publishes the report fully, excluding the annexes. The document highlights limits, inconsistencies and reticence present within the majority report of the parliamentary Antimafia

    This is the first time that the VPDC and RBDM birth data were linked in Victoria. The matched birth information established a more complete population profile of Aboriginal and/or Torres Strait Islander births. These data will provide a more accurate baseline to enhance the Victorian and Australian governments’ ability to plan services, allocate resources and evaluate funded activities aimed at eliminating disparity experienced by Aboriginal and/or Torres Strait Islander peoples. Importantly, it has established a more accurate denominator from which to calculate Aboriginal infant mortality rates for Victoria, Australia. *Until 2009, the mother’s Indigenous identification only was recorded in the VPDC

    A cryopump design of tubular geometry is presented, which incorporates in its vacuum system only a very small fraction of ambient temperature walls. Furthermore, the total amount of the 300K radiation reaching the cold baffles is reduced by about two orders of magnitude. This has the double advantage that the baffles can be cooled at lower temperatures and can be allowed to be more 'transparent' to radiation and hence to molecules. The new model has been entirely optimised both for molecular and radiation transmission by a Monte Carlo method. It is designed to have a pumping speed of 3000 ls/sup -1/ for H/sub 2/ at the two entrances, an axial conductance providing a pressure drop across the pump of a factor of ten and a limit pressure in the 10/sup -14/ Torr range.

    This study sought to determine the construct validity of two self-report measures of attitudes towards Aboriginal Australians and Torres Strait Islanders against an implicit measure of attitude. Total of 102 volunteer participants completed the three measures in a randomized order. The explicit measures of prejudice towards Aboriginal Australians were the Modern Racism Scale (MRS) and the Attitudes Towards Indigenous Australians Scale (ATIAS). The implicit attitudes measure was an adaptation of the Implicit Association Test (IAT) and utilised simple drawn head-and-shoulder images of Aboriginal Australians and White Australians as the stimuli. Both explicit measures and implicit measure varied in the extent to which negative prejudicial attitudes were held by participants, and the corresponding construct validities were unimpressive. The MRS was significantly correlated with the IAT, (r =.314;pAboriginal Australians, only the MRS evidenced validity when compared with the use of an implicit attitude measure.

    Full Text Available Abstract Background Understanding people's social lived experiences of chronic illness is fundamental to improving health service delivery and health outcomes, particularly in relation to self-management activity. In explorations of social lived experiences this paper uncovers the ways in which Aboriginal and Torres Strait Islander people with chronic illness experience informal unsolicited support from peers and family members. Methods Nineteen Aboriginal and Torres Islander participants were interviewed in the Serious and Continuing Illness Policy and Practice Study (SCIPPS. Participants were people with Type 2 diabetes (N = 17, chronic obstructive pulmonary disease (N = 3 and/or chronic heart failure (N = 11 and family carers (N = 3. Participants were asked to describe their experience of having or caring for someone with chronic illness. Content and thematic analysis of in-depth semi-structured interviews was undertaken, assisted by QSR Nvivo8 software. Results Participants reported receiving several forms of unsolicited support, including encouragement, practical suggestions for managing, nagging, growling, and surveillance. Additionally, participants had engaged in 'yarning', creating a 'yarn' space, the function of which was distinguished as another important form of unsolicited support. The implications of recognising these various support forms are discussed in relation to responses to unsolicited support as well as the needs of family carers in providing effective informal support. Conclusions Certain locations of responsibility are anxiety producing. Family carers must be supported in appropriate education so that they can provide both solicited and unsolicited support in effective ways. Such educational support would have the added benefit of helping to reduce carer anxieties about caring roles and responsibilities. Mainstream health services would benefit from fostering environments that encourage informal interactions that

    Alcohol-related harms cause great concern to Aboriginal and Torres Strait Islander (Indigenous) communities in Australia as well as challenges to policy makers. Treatment of alcohol use disorders forms one component of an effective public health response. While alcohol dependence typically behaves as a chronic relapsing condition, treatment has been shown to be both effective and cost-effective in improving outcomes. Provision of alcohol treatment services should be based on accurate assessment of treatment need. In this paper, we examine the likely extent of the gap between voluntary alcohol treatment need and accessibility. We also suggest potential approaches to improve the ability to assess unmet need. Existing methods of assessing the treatment needs of Indigenous Australians are limited by incomplete and inaccurate survey data and an over-reliance on existing service use data. In addition to a shortage of services, cultural and logistical barriers may hamper access to alcohol treatment for Indigenous Australians. There is also a lack of services funded to a level that allows them to cope with clients with complex medical and physical comorbidity, and a lack of services for women, families and young people. A lack of voluntary treatment services also raises serious ethical concerns, given the expansion of mandatory treatment programmes and incarceration of Indigenous Australians for continued drinking. The use of modelling approaches, linkage of administrative data sets and strategies to improve data collection are discussed as possible methods to better assess treatment need.

    Research with a focus on Aboriginal and Torres Strait Islander Australian's (hereafter referred to as Indigenous(1)) needs is crucial to ensure culturally appropriate evidence-based strategies are developed to improve health. However, concerns surrounding this research exist, arising from some previous research lacking community consultation, resulting in little community benefit or infringing on important cultural values. Values and Ethics: Guidelines for Ethical conduct in Aboriginal and Torres Strait Islander Health Research (hereafter referred to as Values and Ethics), developed by The National Health and Medical Research Council of Australia in 2003, is the ethical standard for Indigenous-focused health research. Researchers must address its Values in research design and conduct. However, its impact on research processes is unclear. Local Protocols should also be considered. This review aims to systematically examine practices related to Values and Ethics, Local Protocols and the processes of conducting Indigenous-focused primary healthcare research in collaboration with external researchers. The following electronic databases and grey literature will be searched (2003 to current): MEDLINE, EMBASE, CINAHL, Informit and HealthInfoNet--an Indigenous-specific research and program website. Indigenous-focused research will be included. Research must be conducted in one or more primary healthcare services, in collaboration with external researchers and with a focus on social and emotional well being. One reviewer will review titles and abstracts to remove obviously irrelevant research articles. Full-text research articles will be retrieved and independently examined by two reviewers. Data and quality assessment will be completed by one reviewer and verified by a second reviewer. Quality will be assessed using modified versions of established quality assessment tools. This review will provide information on research processes and the impact of Values and Ethics on

    Full Text Available Resumen: Es común en la crítica del teatro áureo destacar la función metaliteraria del personaje del gracioso. Éste funcionaría como un elemento casi ficticio dentro de la ficción de la comedia (la “ilusión escénica” y sus apartes dramáticos marcan el ritmo de ésta, lo que le serviría a los autores a ejercer una cierta crítica literaria a partir de estos personajes. El siguiente estudio plantea un acercamiento a los albores del teatro laico en la España pre-renacentista que desvela la metateatralidad de las figuras cómicas del teatro prelopista. Sostenemos que la autorreferencialidad del gracioso que tanto ha destacado la crítica es, en realidad, un rasgo heredado de sus antepasados teatrales: los pastores del pacense Bartolomé de Torres Naharro.Summary: Theater critics have insisted upon the metaliterary function of the gracioso stock-character in the Spanish Golden Age. This comic figure works as a quasi-fictitious element within the theatrical fiction (the “scenic illusion”, as some have termed and his dramatic comments and asides would serve to path the rhythm of the scenes. This character could also be used to insert comments of literary criticism The following study approaches dramatis personae of lay Renaissance theater that unveil the metatheatricality of the pre-Lopean comic figures. I thus assert that the self-referentiality of the gracioso is, in fact, a trait inherited from the gracioso´s predecessors, among them the comic shepherds of the Badajoz-born author Bartolomé de Torres Naharro.

    Physical inactivity is a key health risk among Aboriginal and Torres Strait Islander (Indigenous) Australians. We examined perceptions of the Indigenous Marathon Program (IMP) in a remote Torres Strait island community. Semi-structured interviews with community and program stakeholders (n = 18; 14 Indigenous) examined barriers and enablers to running and the influence of the IMP on the community. A questionnaire asked 104 running event participants (n = 42 Indigenous) about their physical activity behaviours, running motivation and perceptions of program impact. Qualitative data were analysed using thematic content analysis, and quantitative data were analysed using descriptive statistics. Interviews revealed six main themes: community readiness, changing social norms to adopt healthy lifestyles, importance of social support, program appeal to hard-to-reach population groups, program sustainability and initiation of broader healthy lifestyle ripple effects beyond running. Barriers to running in the community were personal (cultural attitudes; shyness) and environmental (infrastructure; weather; dogs). Enablers reflected potential strategies to overcome described barriers. Indigenous questionnaire respondents were more likely to report being inspired to run by IMP runners than non-Indigenous respondents. Positive "ripple" effects of the IMP on running and broader health were described to have occurred through local role modelling of healthy lifestyles by IMP runners that reduced levels of "shame" and embarrassment, a common barrier to physical activity among Indigenous Australians. A high initial level of community readiness for behaviour change was also reported. SO WHAT?: Strategies to overcome this "shame" factor and community readiness measurement should be incorporated into the design of future Indigenous physical activity programs. © 2018 Australian Health Promotion Association.

    2017-03-30

    This article highlights the dearth of accurate evidence available to inform the National Disability Insurance Scheme (NDIS) regarding the extent and nature of neurocognitive disability amongst homeless Aboriginal and Torres Strait Islander people. Without accurate prevalence rates of neurocognitive disability, homeless Aboriginal and Torres Strait Islander people are in danger of not being counted by the NDIS and not receiving supports to which they are entitled. Addressing this knowledge gap is challenged by a range of factors, including: (1) the long-term effect of profound intergenerational disenfranchisement of Aboriginal and Torres Strait Islander people; (2) Aboriginal and Torres Strait Islander cultural perspectives around disability; (3) the generally unrecognised and poorly understood nature of neurocognitive disability; (4) the use of research methods that are not culturally safe; (5) research logistics; and (6) the absence of culturally appropriate assessment tools to identify prevalence. It is argued that an accurate evidence base that is informed by culturally safe research methods and assessment tools is needed to accurately guide the Commonwealth government and the National Disability Insurance Agency about the expected level of need for the NDIS. Research within this framework will contribute to the realisation of a truly inclusive NDIS.

    To describe recall of anti-tobacco advertising (mainstream and targeted), pack warning labels, and news stories among a national sample of Aboriginal and Torres Strait Islander smokers, and to assess the association of these messages with attitudes that support quitting, including wanting to quit. A quota sampling design was used to recruit participants from communities served by 34 Aboriginal community-controlled health services and one community in the Torres Strait. We surveyed 1643 Aboriginal and Torres Strait Islander smokers from April 2012 to October 2013. Frequency of recall of advertising and information, warning labels and news stories; recall of targeted and local advertising; attitudes about smoking and wanting to quit. More smokers recalled often noticing warning labels in the past month (65%) than recalled advertising and information (45%) or news stories (24%) in the past 6 months. When prompted, most (82%) recalled seeing a television advertisement. Just under half (48%) recalled advertising that featured an Aboriginal or Torres Strait Islander person or artwork (targeted advertising), and 16% recalled targeted advertising from their community (local advertising). Frequent recall of warning labels, news stories and advertising was associated with worry about health and wanting to quit, but only frequent advertising recall was associated with believing that society disapproves of smoking. The magnitude of association with relevant attitudes and wanting to quit increased for targeted and local advertising. Strategies to tackle Aboriginal and Torres Strait Islander smoking should sustain high levels of exposure to anti-tobacco advertising, news stories and warning labels. More targeted and local information may be particularly effective to influence relevant beliefs and subsequently increase quitting.

    To assess the impact of plain packaging with larger graphic health warnings on perceptions of risk and prestige related to different cigarette brands among Aboriginal and Torres Strait Islander people in the Australian Capital Territory. We hypothesised that the changes would decrease perceptions that 'some cigarette brands are more harmful than others', and that 'some brands are more prestigious than others', and this would be stronger among participants aged ≤35 years, and among smokers compared with non-smokers. Participants completed the survey prior to packaging changes, and were followed up 12 months later (n=98). Repeated measures ANCOVAs assessed perception changes. Following plain packaging implementation, there was a significant reduction in perceptions that 'some cigarette brands are more harmful than others'. There was no overall change in perceptions of prestige. However, there was a significant interaction for age. Analyses indicated a reduction in perceptions that 'some cigarette brands are more prestigious than others' among younger participants (p=0.05), but no change among older participants (p>0.20). There was no interaction for smoking status for perceptions of prestige, indicating smokers' and non-smokers' perceptions did not differ on this measure. These findings provide support for the packaging changes. © 2015 Public Health Association of Australia.

  11. Investigation of coupling between chemistry and discharge dynamics in radio frequency hydrogen plasmas in the Torr regime

    We present the results of a study of a capacitively coupled hydrogen discharge by means of a one-dimensional numerical fluid model and experiments. The model includes a detailed description of the gas-phase chemistry taking into account the production of H - ions by dissociative attachment of H 2 vibrational levels. The population of these levels is described by a Boltzmann vibrational distribution function characterized by a vibrational temperature T V . The effect of the dissociative-attachment reaction on the discharge dynamics was investigated by varying the vibrational temperature, which was used as a model input parameter. Increasing the vibrational temperature from 1000 to 6000 K affects both the chemistry and the dynamics of the electrical discharge. Because of dissociative attachment, the H - ion density increases by seven orders of magnitude and the H - ion density to electron density ratio varies from 10 -7 to 6, while the positive ion density increases slightly. As a consequence, the atomic hydrogen density increases by a factor of three, and the sheath voltage drops from 95 to 75 V. Therefore, clear evidence of a strong coupling between chemistry and electrical dynamics through the production of H - ions is demonstrated. Moreover, satisfactory agreement between computed and measured values of atomic hydrogen and H - ion densities gives further support to the requirement of a detailed description of the hydrogen vibrational kinetics for capacitively coupled radio frequency discharge models in the Torr regime

    Full Text Available Effect of Citrus floral extracts on the foraging behavior of the stingless bee Scaptotrigona pectoralis (Dalla Torre. Stingless bees have an important role as pollinators of many wild and cultivated plant species in tropical regions. Little is known, however, about the interaction between floral fragrances and the foraging behavior of meliponine species. Thus we investigated the chemical composition of the extracts of citric (lemon and orange flowers and their effects on the foraging behavior of the stingless bee Scaptotrigona pectoralis. We found that each type of flower has its own specific blend of major compounds: limonene (62.9% for lemon flowers, and farnesol (26.5%, (E-nerolidol (20.8%, and linalool (12.7% for orange flowers. In the foraging experiments the S. pectoralis workers were able to use the flower extracts to orient to the food source, overlooking plates baited with hexane only. However, orange flower extracts were seemingly more attractive to these worker bees, maybe because of the particular blend present in it. Our results reveal that these fragrances are very attractive to S. pectoralis, so we can infer that within citric orchards they could be important visitors in the study area; however habitat destruction, overuse of pesticides and the competitive override by managed honeybees might have put at risk their populations and thus the ecological services they provide to us.

    Full Text Available The year of 2006 marked the beginning of an innovative project in the field of archives, related with the assessment and evaluation of environmental and biological risks in the Portuguese National Archive, Torre do Tombo. With a first phase in 2006-2007 related with the assessment of environmental and biological risks, in 2009 began the second phase seeking to establish an overall perspective of all risk involved in the deterioration of documentation. The management model defined for Portuguese National Archive, Torre do Tombo sets benchmarks for institutions with the responsibility in safeguarding archival heritage with historical and cultural value, reflecting the progresses since then, in the preventive conservation area – particularly the integration of risk assessment models in its analysis and decision processes. The articulation of management and conservation concepts, allowed the functional optimization of institutions and a sustained comprehension of the different levels involved in preservation, within an organization.

    Reilly, Lyndon; Rees, Susan

    2018-03-01

    Traditional Australian Aboriginal and Torres Strait Islander societies value men's role as parents; however, the importance of promoting fatherhood as a key social determinant of men's well-being has not been fully appreciated in Western medicine. To strengthen the Aboriginal and Torres Strait Islander male parenting role, it is vital to examine current barriers and opportunities. The first author (a male Aboriginal health project officer) conducted yarning sessions in three remote Australian communities, two being Aboriginal, the other having a high Aboriginal population. An expert sample of 25 Aboriginal and 6 non-Aboriginal stakeholders, including maternal and child health workers and men's group facilitators, considered barriers and opportunities to improve men's parenting knowledge and role, with an aim to inform services and practices intended to support men's parenting. A specific aim was to shape an existing men's group program known as Strong Fathers, Strong Families. A thematic analysis of data from the project identified barriers and opportunities to support men's role as parents. Challenges included the transition from traditional to contemporary parenting practices and low level of cultural and male gender sensitivity in maternal and child health services. Services need to better understand and focus on men's psychological empowerment and to address shame and lack of confidence around parenting. Poor literacy and numeracy are viewed as contributing to disempowerment. Communities need to champion Aboriginal and Torres Strait Islander male father role models. Biases and barriers should be addressed to improve service delivery and better enable men to become empowered and confident fathers.

    Full Text Available Abstract Background To develop an instrument that predicts diabetes-related vascular disease severity using routinely collected data on Australian Aboriginal and Torres Strait Islander adults with type 2 diabetes, in the absence of diabetes duration. Methods A complex diabetes severity classification system was simplified and adapted for use with an Australian Aboriginal and Torres Strait Islander adult population with type 2 diabetes in north Queensland. Detailed vascular health risks and morbidities were mapped to routinely collected measures. Individual–level health screening, hospital separation and mortality data were linked and used to plot mean monthly in-patient hospital cost and percent mortality by disease severity as defined by the newly developed instrument, to test construct validity. Results The revised instrument consists of four combined diabetes-related microvascular and macrovascular stages that range from least severe (stage 1 to severe irreversible vascular impairment (stage 4. When applied to data of an Aboriginal and Torres Strait Islander Australian population the instrument showed good construct validity, predicting higher hospital cost and mortality as vascular disease severity increased. Conclusions This instrument discriminates between levels of diabetes-related vascular disease severity, displays good construct validity by predicting increased hospital cost and mortality with worsening severity and can be populated with routinely collected data. It may assist with future health service research and its use could be extended to practice settings for health care planning for diabetes management programs and monitoring vascular disease progression.

    Aboriginal and Torres Strait Islander Community Controlled Health Services (ACCHSs) around Australia have been asked to standardise screening for unhealthy drinking. Accordingly, screening with the 3-item AUDIT-C (Alcohol Use Disorders Identification Test-Consumption) tool has become a national key performance indicator. Here we provide an overview of suitability of AUDIT-C and other brief alcohol screening tools for use in ACCHSs. All peer-reviewed literature providing original data on validity, acceptability or feasibility of alcohol screening tools among Indigenous Australians was reviewed. Narrative synthesis was used to identify themes and integrate results. Three screening tools-full AUDIT, AUDIT-3 (third question of AUDIT) and CAGE (Cut-down, Annoyed, Guilty and Eye-opener) have been validated against other consumption measures, and found to correspond well. Short forms of AUDIT have also been found to compare well with full AUDIT, and were preferred by primary care staff. Help was often required with converting consumption into standard drinks. Researchers commented that AUDIT and its short forms prompted reflection on drinking. Another tool, the Indigenous Risk Impact Screen (IRIS), jointly screens for alcohol, drug and mental health risk, but is relatively long (13 items). IRIS has been validated against dependence scales. AUDIT, IRIS and CAGE have a greater focus on dependence than on hazardous or harmful consumption. Detection of unhealthy drinking before harms occur is a goal of screening, so AUDIT-C offers advantages over tools like IRIS or CAGE which focus on dependence. AUDIT-C's brevity suits integration with general health screening. Further research is needed on facilitating implementation of systematic alcohol screening into Indigenous primary healthcare.

    High blood lead (BPb) levels in children and elevated soil and dust arsenic, cadmium, and lead were previously found in Torreón, northern Mexico, host to the world’s fourth largest lead–zinc metal smelter. The objectives of this study were to determine spatial distributions of adolescents with higher BPb and creatinine-corrected urine total arsenic, cadmium, molybdenum, thallium, and uranium around the smelter. Cross-sectional study of 512 male and female subjects 12–15 years of age was conducted. We measured BPb by graphite furnace atomic absorption spectrometry and urine trace elements by inductively coupled plasma-mass spectrometry, with dynamic reaction cell mode for arsenic. We constructed multiple regression models including sociodemographic variables and adjusted for subject residence spatial correlation with spatial lag or error terms. We applied local indicators of spatial association statistics to model residuals to identify hot spots of significant spatial clusters of subjects with higher trace elements. We found spatial clusters of subjects with elevated BPb (range 3.6–14.7 µg/dl) and urine cadmium (0.18–1.14 µg/g creatinine) adjacent to and downwind of the smelter and elevated urine thallium (0.28–0.93 µg/g creatinine) and uranium (0.07–0.13 µg/g creatinine) near ore transport routes, former waste, and industrial discharge sites. The conclusion derived from this study was that spatial clustering of adolescents with high BPb and urine cadmium adjacent to and downwind of the smelter and residual waste pile, areas identified over a decade ago with high lead and cadmium in soil and dust, suggests that past and/or present plant operations continue to present health risks to children in those neighborhoods.

    Background Mental Health First Aid (MHFA) training was developed in Australia to teach members of the public how to give initial help to someone developing a mental health problem or in a mental health crisis situation. However, this type of training requires adaptation for specific cultural groups in the community. This paper describes the adaptation of the program to create an Australian Aboriginal and Torres Strait Islander Mental Health First Aid (AMHFA) course and presents an initial evaluation of its uptake and acceptability. Methods To evaluate the program, two types of data were collected: (1) quantitative data on uptake of the course (number of Instructors trained and courses subsequently run by these Instructors); (2) qualitative data on strengths, weaknesses and recommendations for the future derived from interviews with program staff and focus groups with Instructors and community participants. Results 199 Aboriginal people were trained as Instructors in a five day Instructor Training Course. With sufficient time following training, the majority of these Instructors subsequently ran 14-hour AMHFA courses for Aboriginal people in their community. Instructors were more likely to run courses if they had prior teaching experience and if there was post-course contact with one of the Trainers of Instructors. Analysis of qualitative data indicated that the Instructor Training Course and the AMHFA course are culturally appropriate, empowering for Aboriginal people, and provided information that was seen as highly relevant and important in assisting Aboriginal people with a mental illness. There were a number of recommendations for improvements. Conclusion The AMHFA program is culturally appropriate and acceptable to Aboriginal people. Further work is needed to refine the course and to evaluate its impact on help provided to Aboriginal people with mental health problems. PMID:19490648

    Background Aboriginal and Torres Strait Islanders (Aboriginal) are Australia's first peoples. Between 2006 and 2015, HIV notifications increased among Aboriginal people; however, among non-Aboriginal people, notifications remained relatively stable. This systematic review and meta-analysis aims to examine the prevalence of HIV among Aboriginal people overall and by subgroups. In November 2015, a search of PubMed and Web of Science, grey literature and abstracts from conferences was conducted. A study was included if it reported the number of Aboriginal people tested and those who tested positive for HIV. The following variables were extracted: gender; Aboriginal status; population group (men who have sex with men, people who inject drugs, adults, youth in detention and pregnant females) and geographical location. An assessment of between study heterogeneity (I 2 test) and within study bias (selection, measurement and sample size) was also conducted. Seven studies were included; all were cross-sectional study designs. The overall sample size was 3772 and the prevalence of HIV was 0.1% (I 2 =38.3%, P=0.136). Five studies included convenient samples of people attending Australian Needle and Syringe Program Centres, clinics, hospitals and a youth detention centre, increasing the potential of selection bias. Four studies had a sample size, thus decreasing the ability to report pooled estimates. The prevalence of HIV among Aboriginal people in Australia is low. Community-based programs that include both prevention messages for those at risk of infection and culturally appropriate clinical management and support for Aboriginal people living with HIV are needed to prevent HIV increasing among Aboriginal people.

    Full Text Available Background: Absolute cardiovascular risk assessment (CVRA is based on the combined effects of multiple risk factors and can identify asymptomatic individuals at high risk of cardiovascular disease. Aboriginal and Torres Strait Islander people are disproportionately affected by cardiovascular disease and diabetes. Our study aimed to investigate variations in the use of absolute CVRA in patients with diabetes at Indigenous community healthcare centres, and to identify patient and health centre characteristics that may contribute to this variation. Methods: Audits of clinical records of 1,728 patients with a known diagnosis of diabetes across 121 health centres over the period 2012–2014 were conducted as part of a large-scale continuous quality improvement program. Multilevel regression modelling was used to quantify variation in recording of CVRA attributable to health centre and patient characteristics. Results: The proportion of eligible patients with documented CVRA was 33% (n=574/1,728. The majority (95% of assessments were conducted in the Northern Territory (NT. Multilevel regression analysis showed health centre characteristics accounted for 70% of the variation in assessments in the NT. Government-operated health centres had 18.8 times the odds (95% CI 7.7–46.2 of recording CVRA delivery compared with other health centres. Conclusion: Health centres in the NT delivered the majority of absolute CVRA to Indigenous patients with diabetes in our study. Health systems factors that may have facilitated provision of CVRA in the NT include decision support tools and a reporting process for CVRA delivery. Implementation of similar systems in other jurisdictions may help improve CVRA delivery. Early identification and treatment of high risk individuals through wider use of CVRA may help reduce the burden of cardiovascular disease in Indigenous Australians with diabetes.

    To characterise lipid profiles for Australian Aboriginal people and Torres Strait Islanders. Community-based, cross-sectional surveys in 1995-1997 including: 407 female and 322 male Australian Aboriginal people and 207 female and 186 male Torres Strait Islanders over 15 years old. A comparator of 78 female (44 with diabetes) and 148 male (73 with diabetes) non-indigenous participants recruited to clinical epidemiological studies was used. Lipids were determined by standard assays and LDL diameter by gradient gel electrophoresis. Diabetes prevalence was 14.8% and 22.6% among Aboriginal people and Torres Strait Islanders, respectively. LDL size (mean [95% CI (confidence interval)]) was smaller (P<0.05) in non-diabetic Aboriginal (26.02 [25.96-26.07] nm) and Torres Strait Islander women (26.01 [25.92-26.09] nm) than in non-diabetic non-indigenous women (26.29 [26.13-26.44] nm). LDL size correlated (P<0.0005) inversely with triglyceride, WHR, and fasting insulin and positively with HDL-cholesterol. HDL-cholesterol (mean [95% CI] mmol/L) was lower (P<0.0005) in indigenous Australians than in non-indigenous subjects, independent of age, sex, diabetes, WHR, insulin, triglyceride, and LDL size: Aboriginal (non-diabetic women, 0.86 [0.84-0.88]; diabetic women, 0.76 [0.72-0.80]; non-diabetic men, 0.79 [0.76-0.81]; diabetic men, 0.76 [0.71-0.82]); Torres Strait Islander (non-diabetic women, 1.00 [0.95-1.04]; diabetic women, 0.89 [0.83-0.96]; non-diabetic men, 1.00 [0.95-1.04]; diabetic men, 0.87 [0.79-0.96]); non-indigenous (non-diabetic women, 1.49 [1.33-1.67]; diabetic women, 1.12 [1.03-1.21]; non-diabetic men, 1.18 [1.11-1.25]; diabetic men, 1.05 [0.98-1.12]). Indigenous Australians have a dyslipidaemia which includes small LDL and very low HDL-cholesterol levels. The dyslipidaemia was equally severe in both genders. Strategies aimed at increasing HDL-cholesterol and LDL size may reduce high CVD risk for indigenous populations.

    The absorption spectrum of HO2 radicals has been measured in the range 6636-6639 cm-1 at several pressures between 20 and 760 Torr of air. Absolute absorption cross sections of the strongest line at around 6638.2 cm-1 have been determined from kinetic measurements, taking advantage of the well known rate constant of the self-reaction. Peak absorption cross sections of 22.6, 19.5, 14.4, 7.88, 5.12 and 3.23 × 10-20 cm2 were obtained at 20, 50, 100, 200, 400 and 760 Torr, respectively. By fitting these data, an empirical expression has been obtained for the absorption cross section of HO2 in the range 20-760 Torr air: σ6638.2cm-1 = 1.18 × 10-20 + (2.64 × 10-19 × (1-exp (-63.1/p (Torr))) cm2.

    Full Text Available Abstract Background Indigenous Australians are a small, widely dispersed population. Regarding childbearing women and infants, inequities in service delivery and culturally unsafe services contribute to significantly poorer outcomes, with a lack of high-level research to guide service redesign. This paper reports on an Evaluation of a specialist (Murri antenatal clinic for Australian Aboriginal and Torres Strait Islander women. Methods A triangulated mixed method approach generated and analysed data from a range of sources: individual and focus group interviews; surveys; mother and infant audit data; and routinely collected data. A retrospective analysis compared clinical outcomes of women who attended the Murri clinic (n=367 with Indigenous women attending standard care (n=414 provided by the same hospital over the same period. Both services see women of all risk status. Results The majority of women attending the Murri clinic reported high levels of satisfaction, specifically with continuity of carer antenatally. However, disappointment with the lack of continuity during labour/birth and postnatally left some women feeling abandoned and uncared for. Compared to Indigenous women attending standard care, those attending the Murri clinic were statistically less likely to be primiparous or partnered, to experience perineal trauma, to have an epidural and to have a baby admitted to the Neonatal Intensive Care Unit, and were more likely to have a non-instrumental vaginal birth. Multivariate analysis found higher normal birth (spontaneous onset of labour, no epidural, non-instrumental vaginal birth without episiotomy rates amongst women attending the Murri clinic. Conclusions Significant benefits were associated with attending the Murri clinic. Recommendations for improvement included ongoing cultural competency training for all hospital staff, reducing duplication of services, improving co-ordination and communication between community and tertiary

    Full Text Available Indigenous Australians experience a substantially higher cancer mortality rate than non-Indigenous Australians. While cancer outcomes are improving for non-Indigenous Australians, they are worsening for Indigenous Australians. Reducing this disparity requires evidence-based and culturally-appropriate guidance. The purpose of this paper is to describe an initiative by Cancer Australia and Menzies School of Health Research (Menzies to develop Australia’s first National Aboriginal and Torres Strait Islander Cancer Framework using a process of co-design with relevant stakeholders. The initiative was guided by three core principles: achieving policy-relevant evidence-based outcomes; engaging and maintaining trust with Indigenous Australians at every phase; and employing best-practice and appropriate research methods. Four components of research comprised the Framework development: evidence review; multifaceted stakeholder consultation and input; triangulation of findings; and direct stakeholder input in drafting and refining the Framework. The evidence review confirmed the increasing burden of cancer on Indigenous Australians, while stakeholder consultations facilitated comprehensive input from those with lived experience. The consultations revealed issues not identified in existing literature, and gave different emphases of priority, thus reinforcing the value of including stakeholder perspectives. This paper focuses primarily on documenting the methods used; findings are presented only in order to illustrate the results of the process. The published Framework is available at www.canceraustralia.gov.au; further description and analyses of findings from the consultations will be published elsewhere. The logistics inherent in large-scale consultation are considerable. However, the quality of data and the foundation for sustained partnership with stakeholders and knowledge translation vastly outweighed the challenges. The process of wide

    Australian Aboriginal and Torres Strait Islander (Indigenous) women are at greater risk of adverse pregnancy outcomes than non-Indigenous women. Pregnancy care has a key role in identifying and addressing modifiable risk factors that contribute to adverse outcomes. We investigated whether participation in a continuous quality improvement (CQI) initiative was associated with increases in provision of recommended pregnancy care by primary health care centers (PHCs) in predominantly Indigenous communities, and whether provision of care was associated with organizational systems or characteristics. Longitudinal analysis of 2220 pregnancy care records from 50 PHCs involved in up to four cycles of CQI in Australia between 2007 and 2012. Linear and logistic regression analyses investigated associations between documented provision of pregnancy care and each CQI cycle, and self-ratings of organizational systems. Main outcome measures included screening and counselling for lifestyle-related risk factors. Women attending PHCs after ≥1 CQI cycles were more likely to receive each pregnancy care measure than women attending before PHCs had completed one cycle e.g. screening for cigarette use: baseline = 73 % (reference), cycle one = 90 % [odds ratio (OR):3.0, 95 % confidence interval (CI):2.2-4.1], two = 91 % (OR:5.1, 95 % CI:3.3-7.8), three = 93 % (OR:6.3, 95 % CI:3.1-13), four = 95 % (OR:11, 95 % CI:4.3-29). Greater self-ratings of overall organizational systems were significantly associated with greater screening for alcohol use (β = 6.8, 95 % CI:0.25-13), nutrition counselling (β = 8.3, 95 % CI:3.1-13), and folate prescription (β = 7.9, 95 % CI:2.6-13). Participation in a CQI initiative by PHCs in Indigenous communities is associated with greater provision of pregnancy care regarding lifestyle-related risk factors. More broadly, these findings support incorporation of CQI activities addressing systems level issues into primary care

    In situ-produced waters collected while retorting oil shale and tar sands to produce oil, and coal to produce gas, were tested for their effects on plant growth. Basin wildrye (Elymus cinereus), western wheatgrass (Agropyron smithii) 'Rosana', alkali sacaton (Sporobolus airoides), bluebunch wheatgrass (Agropyron spicatum) and Nuttall alkaligrass (Puccinellia airoides) were utilized. Root weight, shoot weight, total dry weight, leaf area and root/shoot weight ratios were determined. All experiments were conducted under greenhouse conditions using hydroponic techniques and horticultural grade perlite for plant support. Measurements were collected after a 10-week growth period. Results show that differences in plant growth can be monitored using dry biomass, leaf area and root to shoot ratio measurements when plants are subjected to retort waters. Plant species reaction to a water may be different. Generally, alkali sacaton, basin wildrye and western wheatgrass are least susceptible to toxicity by the majority of retort waters tested. Bluebunch wheatgrass is most susceptible. Waters from different retort procedures vary in toxicity to different plant species.

    Full Text Available En la literatura de Antonio Torres, la presencia de elementos que hacen referencia a las experiencias personales y a las características específicas de su vida, elaborados artísticamente, hace que el memorialismo, que gobierna la narración de la historia d e los personajes, mézclese, a veces, con recuerdos íntimos del escritor. Basando - se en estas características, este artículo pretende estudiar, en las novelas de Antonio Torres, los procedimientos de ficcionalización de la experiencia, dada su importancia e n el proceso de construcción narrativa y en la relación autor - texto - lector. De la lectura dialógica de la totalidad de su obra, buscamos comprender la delineación de un "mito del escritor" o de una personalidad literaria y la consiguiente construcción de u n espacio autobiográfico, que se traduce en un universo ficticio singular donde personajes, temas y situaciones reaparecen con frecuencia, produciendo un enlace comunicativo entre los textos y causando la familiaridad inmediata del lector. Además de la pro ducción de una imagen literaria de Antonio Torres, nos fijamos en cómo la migración de elementos personales a su obra permite la entrada de información de la realidad socio - política de que es testigo en la esfera ficcional. Aprovechando su tierra y su pueb lo para retratar el impacto del cambio social en la gente del sertão del noreste de Brasil, la obra del autor termina expresando la preocupación de mostrar la crisis de identidad de estos sujetos del noreste, unida a los recuerdos de un pasado que no se re concilia al momento actual.

    Full Text Available Comentando ciertas adaptaciones cinematográficas de obras literarias de Adolfo Bioy Casares el crítico de cine Sergio Wolf escribe: „[L]a narrativa del autor es en sí ‚una trampa para cineastas‘ aunque prometa ser ‚una trama para cineastas‘.“ Leopoldo Torre Nilsson no sólo rodó La mano en la trampa, sino fue también el primero en meter la mano en esa trampa que constituyen las narraciones de Bioy, porque su primer propio largometraje, El crimen de Oribe, basado en el cuento “El perjurio de la nieve”, es la primera transposición fílmica de una obra de su compatriota.En ese cuento Bioy construye un laberinto de declaraciones contradictorias sobre la misteriosa muerte de una joven muchacha, las cuales fuerzan al lector a hacer su propia investigación – una investigación que el autor quiere explícitamente literaria, porque para indicar pistas al lector hace comentar a sus personajes los manuscritos escritos por otros, lo que significa un desafío para cada adaptación fílmica. Nuestro artículo intenta mostrar cómo Torre reacciona ante este desafío; especial atención se presta a su tratamiento del motivo principal de la investigación así que al rol de un cosmos cerrado, tan importante en toda la obra de Torre Nilsson como en la de Bioy, y en otro procedimiento apreciado por el director y el autor a la vez, la mise en abyme.

    Non-suicidal self-injury (NSSI) disproportionally affects Indigenous Australians. Friends, family and frontline workers (for example, teachers, youth workers) are often best positioned to provide initial assistance if someone is engaging in NSSI. Culturally appropriate expert consensus guidelines on how to provide mental health first aid to Australian Aboriginal and Torres Strait Islanders who are engaging in NSSI were developed in 2009. This study describes the re-development of these guidelines to ensure they contain the most current recommended helping actions. The Delphi consensus method was used to elicit consensus on potential helping statements to be included in the guidelines. These statements describe helping actions that Indigenous community members and non-Indigenous frontline workers can take, and information they should have, to help someone who is engaging in NSSI. The statements were sourced from systematic searches of peer-reviewed literature, grey literature, books, websites and online materials, and existing NSSI courses. A panel was formed, comprising 26 Aboriginal and Torres Strait Islanders with expertise in NSSI. The panellists were presented with the helping statements via online questionnaires and were encouraged to suggest re-wording of statements and any additional helping statements that were not included in the original questionnaire. Statements were only accepted for inclusion in the guidelines if they were endorsed by ≥90% of panellists as essential or important. From a total of 185 statements shown to the expert panel, 115 were endorsed as helping statements to be included in the re-developed guidelines. A panel of Aboriginal and Torres Strait Islander people with expertise in NSSI were able to reach consensus on appropriate strategies for providing mental health first aid to an Aboriginal and Torres Strait Islander engaging in NSSI. The re-development of the guidelines has resulted in more comprehensive guidance than the earlier

    Full Text Available Abstract Background Aboriginal and Torres Strait Islander women have a higher prevalence and incidence of obesity and type 2 diabetes than non-Indigenous Australian women. Physical inactivity is a key modifiable risk factor for obesity and evidence shows that even modest reductions in waist circumference (WC have significant health benefits. Trialing physical activity programs in difficult-to-reach high risk groups, especially urban Indigenous Australians poses distinct implementation challenges. Methods/Design The trial objective is to evaluate the effectiveness of a structured 12-week physical activity group program with nutritional advice. The design is a pragmatic randomised controlled trial. This study protocol describes the implementation and evaluation of the program. Participants are randomised into either an intervention or waitlisted group. The waitlisted group have a 12 month waiting period before commencing the 12-week program. Participant data is collected at baseline, 12, 24 and 52 weeks. Participants are Aboriginal and Torres Strait Islander women, aged 18-64 years with a waist circumference greater than 80 centimetres residing in Adelaide. The primary outcome measure is WC change immediately post program from baseline. Secondary outcomes include short term and long term changes in WC, weight, blood pressure, fasting blood glucose, insulin, insulin resistance (calculated HOMA, haemoglobin A1C (HbA1C, triglycerides and C-reactive protein (CRP.

    MacDonald, John C.

    The new Australian ship reporting system, identifier , will be the core component of a Vessel Traffic Information Service (VTIS) covering the Torres Strait region and the Great Barrier Reef (GBR). It is the first such system to be considered by the International Maritime Organization (IMO) under the terms of the new SOLAS 74 regulation v/8-1, which entered into force on 1 January 1996 and allows for ship reporting systems adopted by the Organization to be made mandatory for all, or certain categories of vessels.The REEFREP system, planned for implementation on 1 January 1997, extends for some 900 n.m. or about 1500 km along the Queensland coastline. It will be a VHF radio-based system with radars covering three selected focal points in the Torres Strait, off Cairns and in the southern approaches to the inner route. The system will provide a capability for a single Ship Reporting Centre to interact with shipping, enabling the provision of improved information on the presence, movements and patterns of shipping in the area and the ability to respond more quickly to an incident or pollution should this occur.An interesting feature and a major factor in the system design is the remoteness of most equipment sites and the limited infrastructure available to support communications and data transmission requiring the application of advanced technology and video transmission, solar power generation and software engineering skills of a high order.

El vacuno supone el principal recurso ganadero de la ocupación prerromana complementada, marginalmente, con el ganado lanar, caprino y porcino. La escasa frecuencia de los restos de caballo y perro constatan un patrón habitual en la mayoría de los yacimientos protohistóricos, aunque el despiece exhaustivo de algunos canes no descarta el consumo de estos carnívoros. La actividad cinegética resulta ser testimonial como complemento a la dieta, representada tan sólo por el ciervo.ABSTRACT: The study of the faunal remains of Campa Torres has allowed to approximate us to the paleoeconomical patterns of one of the most important fortified Iron Age hillforts in Asturias. The cattle supposes the main stock during the prerroman occupation, complemented marginally with the sheep, goat and pig. The low frequency of the horse and dog bones states a habitual pattern as in most of the prehistoric sites, although the exhaustive disarticulation marks of dogs do not discard the consume of these carnivores. The hunting activities are evidenced only by some testimonial remains of red dear.

    Lower socioeconomic status has been linked to long-term stress, which can manifest in individuals as physiological stress. The aim was to explore the relationship between low socioeconomic status and physiological stress in Aboriginal and Torres Strait Islander Australians. Using data from the eGFR Study (a cross-sectional study of 634 Indigenous Australians in urban and remote areas of northern and central Australia), we examined associations between resting heart rate and demographic, socioeconomic, and biomedical factors. An elevated resting heart rate has been proposed as a measure of sustained stress activation and was used as a marker of physiological stress. Relationships were assessed between heart rate and the above variables using univariate and multiple regression analyses. We reported a mean resting heart rate of 74 beats/min in the cohort (mean age 45 years). On multiple regression analysis, higher heart rate was found to be independently associated with Aboriginal ethnicity, being a current smoker, having only primary level schooling, higher HbA1c and higher diastolic blood pressure (model R(2) 0.25). Elevated resting heart rate was associated with lower socioeconomic status and poorer health profile in Aboriginal and Torres Strait Islander Australians. Higher resting heart rate may be an indicator of stress and disadvantage in this population at high risk of chronic diseases.

    Middle ear disease (otitis media) is endemic among Aboriginal and Torres Strait Islander children in Australia and represents an important cause of hearing loss. The disease is the result of a mix of biological, environmental and host risk factors that interact in complex, non-linear ways along a dynamic continuum. As such, it is generally recognised that a holistic, systems approach is required to reverse the high rates of otitis media in Aboriginal and Torres Strait Islander children. The objective of this paper is to examine the alignment between efforts designed to address otitis media in Aboriginal and Torres Strait Islander children in Queensland, Australia and core concepts of systems thinking. This paper's overall purpose is to identify which combination of activities, and at which level, hold the potential to facilitate systems changes to better support ear health among Aboriginal and Torres Strait Islander children. We began with a review of documents identified in consultation with stakeholders and an online search. In addition, key informants were invited to participate in an online survey and a face-to-face or phone interview. Qualitative interviews using a semi-structured interview guide were used to explore survey responses in more depth. We also undertook interviews at the community level to elicit a diverse range of views. Ideas, statements or activities reported in the documents and interviews as being performed under the Intervention Level Framework were identified using qualitative thematic and content analysis. A quantitative descriptive analysis was also undertaken, whereby data was extracted into an Excel spreadsheet and coded under the relevant strategic directions and performance indicators of the Framework. Subsequently, we coded activities against the five-level intervention framework developed by Malhi and colleagues, that is: 1) paradigm; 2) goals; 3) system structure; 4) feedback and delays; and 5) structural elements.

    Background The prevalence of food insecurity is substantially higher among Australians of Aboriginal or Torres Strait Islander descent. The purpose of this study is to explain the relationship between food insecurity and Aboriginal and Torres Islander status in the state of Victoria. Methods Data were obtained from the 2008 Victorian Population Health Survey; a cross-sectional landline computer-assisted telephone interview survey of 34,168 randomly selected Victorians aged 18 years and older; including 339 Aboriginal and Torres Strait Islanders. We categorised a respondent as food insecure, if in the previous 12 months, they reported having run out of food and not being able to afford to buy more. We used multivariable logistic regression to adjust for age, sex, socioeconomic status (household income), lifestyle risk factors (smoking, alcohol consumption and obesity), social support (ability to get help from family, friends or neighbours), household composition (lone parent status, household with a child, and household size), and geographic location (rurality). Results Aboriginal and Torres Strait Islanders (20.3%) were more likely than their non-Aboriginal and Torres Strait Islander counterparts (5.4%) to have experienced food insecurity; odds ratio (OR) = 4.5 (95% CI; 2.7-7.4). Controlling for age, SES, smoking, obesity and inability to get help from family or friends reduced the odds ratio by 38%; ORadjusted = 2.8 (1.6-5.0). Conclusions Social determinants and lifestyle risk factors only partially explained the higher prevalence of food insecurity among Aboriginal and Torres Strait Islanders in Victoria. Further research is needed to explain the disparity in food insecurity between the two populations in order to inform and guide corrective action. PMID:24924598

    Full Text Available To better understand the sociopolitical landscape of the Portuguese Estremadura during the Late Neolithic/Copper Age, interdisciplinary excavations were conducted at Bolores (Torres Vedras, in the Sizandro River Valley. Following a test season in 1986, a University of Iowa team conducted four campaigns between 2007 and 2012. Bolores is a rock-cut tomb used primarily between 2800-2600 cal BC for the burial of adults, adolescents, and children (MNI=36. The architectural, material cultural, and bioarchaeological evidence suggests that Bolores housed the remains of a distinctive group of local individuals who marked their difference from other burial populations in the Sizandro and Estremadura through material culture and tomb architecture. Social differences were denoted spatially and through offerings of material goods. No social stratification is evident, however, that would suggest a state-level society: there are no wealthy child burials and no significant health or dietary disparities within this population or between it and others in the region.Para comprender mejor el paisaje sociopolítico de la Extremadura portuguesa durante el Neolítico Final/Edad del Cobre se han llevado a cabo excavaciones interdisciplinares en Bolores (Torres Vedras, en el valle del río Sizandro.

    Full Text Available A Aganglionose Intestinal Congênita (AIC, ou Doença de Hirschprung, é uma má formação caracterizada pela ausência de células ganglionares nos plexos mioentérico e submucoso da porção distal do trato gastrointestinal. Assim, o segmento aganglionar é aperistáltico e espástico, constituindo um obstáculo ao transito intestinal e gerando a dilatação do segmento saudável. A doença costuma manifestar-se no período neonatal com obstrução intestinal, distensão abdominal e vômitos. O tratamento é cirúrgico, pela técnica de De La Torre-Mondragon, realizada em um tempo cirúrgico e sem colostomia prévia. Relato do caso: P.R.D., masculino, 33 dias de vida, foi encaminhado ao serviço com quadro de distensão abdominal e parada da eliminação de fezes há 22 horas. Foi internado primeiramente aos cinco dias de vida com quadro de obstrução intestinal, aliviada após limpeza mecânica. Encontrava-se com abdômen distendido, flácido, sem sinais de desconforto à palpação e ruídos hidroaéreos presentes. O enema opaco evidenciou progressão do contraste com dilatação do retossigmoide. A manometria retal demonstrou reflexo inibitório anorretal não desencadeado, com inúmeras evacuações do lactente durante o exame. Foi indicada correção cirúrgica feita pela técnica de De La Torre-Mondragon, sem intercorrências. Anatomopatológico da peça cirúrgica confirmou ausência de células ganglionares no segmento. O diagnóstico preciso e o manejo cirúrgico precoce foi fundamental para evitar a principal complicação desta doença, a enterocolite necrosante. A técnica de De La Torre-Mondragon consiste no rebaixamento transanal endorretal do cólon e permitiu a recuperação do transito intestinal precocemente, sem a necessidade de colostomia. O reestabelecimento precoce do transito intestinal melhorou a qualidade de vida do paciente e diminuiu custos e o tempo de hospitalização.

    In the framework of a Singular Strategic Project entitled: A dvanced Technologies of Carbon, Capture and Storage (CCS) , supported by the MICINN (Spain) and the FEDER founds (EU), specifically in the Carbon Storage Task, a comprehensive study on the CO 2 leakage as DIC (Dissolved Inorganic Carbon) in the Alicun de Las Torres (Prov. of Granada) natural analogue thermal system was envisaged. This analogous system is characterised by the presence of a very important travertine formation, which can be considered as a permanent and stable sink for CO 2 . In order to explain the formation of these travertine mass an hydrogeological and hydrogeochemical model of the area has been established by using the hydrochemical data, the stable and radioactive isotope characteristics, the dissolved inorganic carbon, as well as the chemical and isotopic composition of the free and dissolved gases of the above mentioned Thermal System.

    Full Text Available The development of a management model, in the preventive conservation area in the National Archive Torre do Tombo, included the identification of the specificities related to assessment and risk management methodology in Archives area/field and the definition of concepts and processes connected to management in that context. The present paper will focus on those contributions, particularly in the changes resulting by a new perspective in terms of management, based in the methodology defined by the AS/NZS 4360 standard. It also represents the end of the characterization of a process with two sequential phases, corresponding to the periods 2006-2007 and 2009-2013, which intention was to reinforce management assumptions in the preventive conservation field.

    Full Text Available The shape of the Eiffel Tower has been discussed several times, seeking for physical and mathematical relationships. This article aims to address this analysis from a different point of view: the historical and sequential evolution of design over the course of the Eiffel company. Thus, the relationship between the experience gained in different works and technicians can be verified. The paper also tries to give merit to work of all the collaborators of Eiffel over those years. In short, the final solution of the Tower is contrasted and corroborated as a great example of structural art, as has been described in the past.La forma de la Torre Eiffel ha sido varias veces analizada, buscando relaciones físicas y matemáticas. Este artículo pretende abordar este análisis desde un punto de vista diferente, la evolución histórica y secuencial del diseño a lo largo de la trayectoria de la empresa de Eiffel. De esta manera, puede comprobarse la relación entre la experiencia acumulada en diferentes obras y técnicos. Se intenta además atribuir los méritos que corresponden a todos los colaboradores de Eiffel a lo largo de esos años. En definitiva, se contrasta y corrobora de esta manera a la solución final de la Torre como un magnífico ejemplo de arte estructural, como ya ha sido descrito en otras ocasiones.

    Leafmining flies (Diptera: Agromyzidae) can be serious economic pests of horticultural crops. Some genera such as Liriomyza are particularly problematic with numerous species, some of which are highly polyphagous (wide host range), which can only be confidently identified morphologically from adult males. In our study, DNA barcoding was employed to establish new locality records of the vegetable leafminer fly, Liriomyza sativae, from the islands of Torres Strait (Queensland, Australia) and the central highlands of Papua New Guinea (PNG). These records represent significant range extensions of this highly invasive plant pest. Specimens of immature leafminers (from leaf mines) were collected over a 5-year period during routine plant health surveys in ethanol or on FTA® filter paper cards, both methods proved effective at preserving and transporting insect DNA under tropical conditions, with FTA cards possessing some additional logistical benefits. Specimens were identified through sequencing two sections of the cytochrome oxidase I gene and the utility of each was assessed for the identification of species and intra-specific genetic lineages. Our study indicates that multiple haplotypes of L. sativae occur in PNG, while a different haplotype is present in the Torres Strait, with genetic regionalization between these areas apart from a single possible instance - one haplotype 'S.7' appears to be common between these two regions - interestingly this has also been the most common haplotype detected in previous studies of invasive L. sativae populations. The DNA barcoding methods employed here not only identified multiple introductions of L. sativae, but also appear generally applicable to the identification of other agromyzid leafminers (Phytomyzinae and Agromyzinae) and should decrease the likelihood of potentially co-amplifying internal hymenopteran parasitoids. Currently, L. sativae is still not recorded from the Australian mainland; however, further sampling of

    Full Text Available La planificación es un concepto clave de la función ejecutiva que permite a las personas generar un plan de acción necesario para la resolución eficaz de un problema con un propósito. Se trata de una capacidad que se desarrolla desde la infancia hasta mediados de la adolescencia y es fundamental para un funcionamiento cotidiano eficaz. El objetivo de este trabajo es determinar el poder predictivo de la edad y la inteligencia sobre la planificación en una muestra de niños de 6 a 13 años de edad. La muestra estuvo conformada por 240 niños divididos equitativamente en cuatro grupos etarios: 6, 8, 11 y 13. Se administró la prueba Torre de Londres y dos pruebas de la Escala de Inteligencia para Niños de Wechsler. Para determinar el grado de asociación entre las variables, se realizaron análisis de correlación, y para determinar el poder predictivo de la edad y la inteligencia sobre la planificación se realizó un análisis de regresión lineal. Los resultados muestran que ambas variables —edad e inteligencia— se asocian positivamente con el desempeño en Torre de Londres, y que también esas variables tienen un poder predictivo sobre el rendimiento en la tarea de planificación. Los datos permiten concluir que la planificación es una habilidad que se desarrolla a lo largo de la infancia y principios de la adolescencia, y que el nivel intelectual tiene un efecto en la capacidad para generar planes a partir de problemas con un propósito.

    Full Text Available A number of glacial moraines are distributed from the eastern margin of the Torres del Paine drainage basin to near the present margin of the Patagonian Ice Fields, together with a set of regionally continuous lacustrine terraces related to glacial fluctuations. The geomorphology, supported by lake sediment evidence, indicates the existence of a single proglacial paleolake in this area, here referred to as the Great Tehuelche Paleolake. This concept helps to clarify the chronology of glacial events and leads to a better understanding of the evolution of the hydrologic system in the Torres del Paine area. Glacial advances previously referred to as A, B and C occurred during the Last Glacial Maximum and fed the Great Tehuelche Paleolake with meltwater, allowing it to reach its maximum extension. The discovery of thrombolites at Laguna Amarga suggests that the drainage of the paleolake towards the Última Esperanza Fjord took place at 7,113 Cal. yr BP, after the melting of an ice barrier that existed during the earlier glacial advance. This gave rise to the development of a complex fluvio-lacustrine hydrologic system that persists to the present day.Un grupo de morrenas glaciales están distribuidas desde el margen este de la cuenca de drenaje de Torres del Paine hacia el margen actual de los Campos de Hielo Patagónicos. Las morrenas se observan en conjunto con un grupo de terrazas lacustres regionales, las cuales están vinculadas a las fluctuaciones glaciales. La geomorfología y evidencias de sedimentos lacustres indican la existencia de un único lago proglacial, referido en este estudio como Gran Paleolago Tehuelche. Este concepto ayuda a clarificar la cronología de los eventos glaciales y permite una mejor comprensión de la evolución del sistema hidrológico del sector de Torres del Paine. Los eventos glaciales, previamente referidos como Avance A, B y C, ocurrieron durante el Último Máximo Glacial y alimentaron con aguas de fusión al

    The Aboriginal and Torres Strait Islander community has an increased risk of developing chronic illnesses including diabetes. Among people with diabetes, foot complications are common and make a significant contribution to the morbidity and mortality associated with this disease. The aim of this review was to systematically evaluate the literature comparing the rates of diabetes related foot complications in Aboriginal and Torres Strait Islander Australians to non-Indigenous Australians. MEDLINE, EMBASE, The Cochrane Library; PUBMED and CINAHL were searched from inception until August 2016. Inclusion criteria were: published cross-sectional or longitudinal studies reporting the prevalence of diabetes related foot complications in both a cohort of Aboriginal and Torres Strait Islander Australians and a cohort of one other Australian population of any age with diabetes. Risk of bias was assessed using the STROBE tool. Eleven studies including a total of 157,892 participants were included. Studies were set in Queensland, the Northern Territory and Western Australia, primarily in rural and remote areas. Aboriginal and Torres Strait Islander Australians experienced substantially more diabetes related foot complications with the mean age up to 14 years younger than non-Indigenous Australians. Aboriginality was associated with increased risk of peripheral neuropathy, foot ulceration and amputation. In several studies, Aboriginal and Torres Strait Islander Australians accounted for the vast majority of diabetes related foot complications (up to 91%) while comprising only a small proportion of the regional population. Reporting quality as assessed with the STROBE tool showed underreporting of: methods, sample description and potential sources of bias. There are no data available for some Australian states and for specific types of diabetes related foot complications. Aboriginal and Torres Strait Islander Australians have a 3-6 fold increased likelihood of experiencing a

    Full Text Available Abstract Background Statistical time series derived from administrative data sets form key indicators in measuring progress in addressing disadvantage in Aboriginal and Torres Strait Islander populations in Australia. However, inconsistencies in the reporting of Indigenous status can cause difficulties in producing reliable indicators. External data sources, such as survey data, provide a means of assessing the consistency of administrative data and may be used to adjust statistics based on administrative data sources. Methods We used record linkage between a large-scale survey (the Western Australian Aboriginal Child Health Survey, and two administrative data sources (the Western Australia (WA Register of Births and the WA Midwives’ Notification System to compare the degree of consistency in determining Indigenous status of children between the two sources. We then used a logistic regression model predicting probability of consistency between the two sources to estimate the probability of each record on the two administrative data sources being identified as being of Aboriginal and/or Torres Strait Islander origin in a survey. By summing these probabilities we produced model-adjusted time series of neonatal outcomes for Aboriginal and/or Torres Strait Islander births. Results Compared to survey data, information based only on the two administrative data sources identified substantially fewer Aboriginal and/or Torres Strait Islander births. However, these births were not randomly distributed. Births of children identified as being of Aboriginal and/or Torres Strait Islander origin in the survey only were more likely to be living in urban areas, in less disadvantaged areas, and to have only one parent who identifies as being of Aboriginal and/or Torres Strait Islander origin, particularly the father. They were also more likely to have better health and wellbeing outcomes. Applying an adjustment model based on the linked survey data increased

    There is a 70% higher age-adjusted incidence of heart failure (HF) among Aboriginal and Torres Strait Islander people, three times more hospitalisations and twice as many deaths as among non-Aboriginal people. There is a need to develop holistic yet individualised approaches in accord with the values of Aboriginal community health care to support patient education and self-care. The aim of this study was to re-design an existing HF educational resource (Fluid Watchers-Pacific Rim) to be culturally safe for Aboriginal and Torres Strait Islander peoples, working in collaboration with the local community, and to conduct feasibility testing. This study was conducted in two phases and utilised a mixed-methods approach (qualitative and quantitative). Phase 1 used action research methods to develop a culturally safe electronic resource to be provided to Aboriginal HF patients via a tablet computer. An HF expert panel adapted the existing resource to ensure it was evidence-based and contained appropriate language and images that reflects Aboriginal culture. A stakeholder group (which included Aboriginal workers and HF patients, as well as researchers and clinicians) then reviewed the resources, and changes were made accordingly. In Phase 2, the new resource was tested on a sample of Aboriginal HF patients to assess feasibility and acceptability. Patient knowledge, satisfaction and self-care behaviours were measured using a before and after design with validated questionnaires. As this was a pilot test to determine feasibility, no statistical comparisons were made. Phase 1: Throughout the process of resource development, two main themes emerged from the stakeholder consultation. These were the importance of identity, meaning that it was important to ensure that the resource accurately reflected the local community, with the appropriate clothing, skin tone and voice. The resource was adapted to reflect this, and members of the local community voiced the recordings for the

The "Hercules Tower is actually a lighthouse built by the Romans between the I and II centuries D.C.. In 1791, the Roman structure, which had lost the whole of its exterior facade and the ramp that used to surround it, was reconstructed. It was covered with a masonry veneer thus reproducing, with neoclassical stylistic elements, the form" of the Roman Lighthouse. The work we present here consisted of the following: developing of the planimetry with the ground photographic mapmaking; the identification of the Roman walls and their transformations; the archaeological excavations; the restoration of the walls and new bronze carpentry; the restoration of this neoclassical work eliminating and relocating the modern semi-detached dwellings; the transfer of the installations to permit the visit of the Roman areas which were adequately illuminated; new handrail and bronze locks; and the rehabilitation of the surroundings of the monument with the "archaeological park" with all necessary services.

    Background With increasing evidence for the effectiveness of e-mental health interventions for enhancing mental health and well-being, a growing challenge is how to translate promising research findings into service delivery contexts. A 2012 e-mental health initiative by the Australian Federal Government (eMHPrac) has sought to address the issue through several strategies, one of which has been to train different health professional workforces in e-mental health (e-MH). Objective The aim of the study was to report on the barriers and enablers of e-MH uptake in a cohort of predominantly Aboriginal and Torres Strait Islander health professionals (21 Indigenous, 5 non-Indigenous) who occupied mainly support or case management roles within their organizations. Methods A 3- or 2-day e-MH training program was followed by up to 5 consultation sessions (mean 2.4 sessions) provided by the 2 trainers. The trainer-consultants provided written reports on each of the 30 consultation sessions for 7 consultation groups. They were also interviewed as part of the study. The written reports and interview data were thematically analyzed by 2 members of the research team. Results Uptake of e-MH among the consultation group was moderate (22%-30% of participants). There were significant organizational barriers to uptake resulting from procedural and administrative problems, demanding workloads, prohibitive policies, and a lack of fit between the organizational culture and the introduction of new technologies. Personal barriers included participant beliefs about the applicability of e-MH to certain populations, and workers’ lack of confidence and skills. However, enthusiastic managers and tech-savvy champions could provide a counter-balance as organizational enablers of e-MH; and the consultation sessions themselves appear to have enhanced skills and confidence, shifted attitudes to new technologies, and seeded a perception that e-MH could be a valuable health education resource

    Full Text Available The Torre del Salvador together with the rest of the Mudejar architecture of Teruel was included in the World Heritage List in Í986. Its restoration, promoted by the Aragón Government, has kept in mind its value as architectural element, a key piece of the Mudejar style of Aragón and Spain and as a symbolic part of the city. Paying attention to these meanings, the intervention tries to extend its survival and return it its splendor. There are no spatial transformations but merely an encounter with the traditional materials, a study and a contemporary interpretation of them and of the techniques through which they were applied. It was necessary to pay special attention to the plaster since it was the only composite used, as well as to another fundamental part of the Mudejar style of Teruel, the glazed ceramics of the facades, partly lost or deteriorated. The article tries to transmit the methodology of the project and the work which, together with the close familiarity with the building itself have been essential in the documentary and complementary studies.

In the first case, the study of the Torres de Serranos, which are constructed entirely of stonework, the interpretation of material data meant a combination of the stratigraphic analysis method with chronotypological criteria. In the second case, a tower of the Homenaje del Castillo de Confrentes, in addition to stratigraphic wall analysis the restoration project was also carried out. On this particular occasion it was possible to reflect on the conservation of stratigraphic data as fundamental elements in the conservation of the building’s materiality.En el texto se presentan dos casos donde la aplicación del análisis estratigráfico constructivo representó, además de la posibilidad de realizar una hipótesis de fases constructivas, la herramienta utilizada para el estudio de la materialidad del monumento (materiales, técnicas constructivas, etc. y la guía para la realización de un proyecto de restauración y una obra más consciente de la materialidad misma. En el primer caso, el estudio de las Torres de Serranos, enteramente construidas en fábrica de sillería, la interpretación de los datos materiales implicó la combinación del método del análisis estratigráfico con criterios cronotipológicos. En el segundo caso, en la torre del Homenaje del Castillo de Cofrentes, además del análisis estratigráfico constructivo se realizó el proyecto de restauración.

    Cumulate and crystal mush disruption and reactivation are difficult to recognise in coarse grained shallow plutonic rocks. Mafic minerals included in hornblende and zoned plagioclase provide snapshots of early crystallization and cumulate formation, but are difficult to interpret in terms of the dynamics of magma ascent and possible links between silicic and mafic rock emplacement. We will present the field relations, the microtextures and the mineral chemistry of the Miocene mafic sill complex of the Torres del Paine intrusive complex (Patagonia, Chile) and its sub-vertical feeder-zone. The mafic sill complex was built up by a succession of braided sills of shoshonitic and high-K calc-alkaline porphyritic hornblende-gabbro and fine grained monzodioritic sills. The mafic units were over-accreted over 41±11 ka, underplating the overlying granite. Local diapiric structures and felsic magma accumulation between sills indicate limited separation of intercumulus liquid from the mafic sills. Anhedral hornblende cores, with olivine + clinopyroxene ± plagioclase ± apatite inclusions, crystallized at temperatures >900°C and pressures of ~300 to ~500 MPa. The corresponding rims and monzodiorite matrix crystallized at 950°C) from the middle crust reservoir to the emplacement level. We show that hornblende-plagioclase thermobarometry is a useful monitor for the determination of segregation conditions of granitic magmas from gabbroic crystal mushes, and for monitoring the evolution of shallow crustal magmatic crystallization, decompression and cooling.

    Higher notification rates of sexually transmissible infections (STIs) are reported among Aboriginal and Torres Strait Islander (Aboriginal) compared with non-Aboriginal people in Australia. The aim of this study is to estimate the pooled prevalence of chlamydia, gonorrhoea, syphilis and trichomonas among Aboriginal people in Australia by sex, age-group, setting (clinic vs population/community-based) and population group [adults, pregnant females, young people (12-29 years) and prisoners].

    In the framework of a Singular Strategic Project entitled: Advanced Technologies of Carbon, Capture and Storage (CCS)1', supported by the MICINN (Spain) and the FEDER founds (EU), specifically in the Carbon Storage Task, a comprehensive study on the CO 2 leakage as DIG (Dissolved Inorganic Carbon) in the Alicun de Las Torres (Prov. of Granada) natural analogue thermal system was envisaged. This analogous system is characterised by the presence of a very important travertine formation, which can be considered as a permanent and stable sink for CO 2 . Consequently, the estimation of the travertine mass has been a main objective of this investigation. For that, data from two complementary electrical tomography campaigns, previously treated by a powerful geostatistical tool, have been used, as well as the porosity average value of this travertine and the calcite density. Besides this, the statistical methodology applied has also allowed the establishment of a 3-D model of the travertine formation, displaying the geological contact between this formation and the underlying materials, as well as the contacts among the three units forming the travertine formation.

    Full Text Available En este artículo se analiza la propuesta novelesca de Los últimos espectadores del acorazado Potemkin, de Ana Teresa Torres (Venezuela, desde tres perspectivas. La primera examina la manera en que el texto se erige como indagación del carácter ficticio –en tanto construcción lingüística y narrativa– de los relatos sobre la realidad; la segunda perspectiva destaca el uso de diversos tipos de estrategias narrativas (autobiografía, novela rosa, cuento, la carta amorosa, el lenguaje periodístico, largos diálogos, que se conjugan en una estructura de carácter polifónico que permite el entrecruzamiento de distintas visiones sobre la historia venezolana; la tercera perspectiva de análisis se centra en la revisión irónica y descarnada de las acciones revolucionarias en Venezuela desde los caudillos hasta la subversión izquierdista de los años sesenta. Se concluye proponiendo que la novela venezolana ha medido mejor que cualquier otro tipo de discurso el carácter violento y antiinstitucional que ha signado la historia nacional y que ha tenido su manifestación última con la actual revolución bolivariana.

    Full Text Available La propiedad literaria surge en Colombia a finales del siglo XIX de forma simultánea a la construcción de la identidad colombiana y latinoamericana. La vida de José María Torres Caicedo y su papel en la Asociación Literaria y Artística Internacional (ALAI muestran que el discurso sobre la propiedad intelectual reforzó la idea de la existencia de una literatura nacional y la nacionalidad, tanto a nivel de América Latina como de Colombia. En este artículo, el interés poscolonial en el mercado editorial y en la propiedad intelectual será estudiado como parte del imperialismo pacífico o imperialismo cultural, en relación con el surgimiento del hispanismo y la identidad latinoamericana. Este enfoque resalta el carácter simbólico y ritual de los acuerdos internacionales y de la legislación nacional sobre derechos de autor y las ganancias para el capital político y cultural de los promotores de la propiedad intelectual. En Colombia la propiedad literaria le permitió a la élite letrada conservadora la aceptación de España y el establecimiento de su hegemonía cultural en Colombia.

  20. Monoterpene concentrations in fresh, senescent, and decaying foliage of singleleaf pinyon (Pinus monophylla Torr. & Frem.: Pinaceae) from the western Great Basin.

    Senescent foliage from pines is potentially a large contributor to the total monoterpene content of the litter layer, and the availability of these compounds as phytotoxins may result from release of these compounds into the vapor phase. In order to determine the fate of several monoterpene hydrocarbons in the natural environment, we examined their concentrations in fresh, senescent, and decaying needles from 32 single-leaf pinyon pine (Pinus monophylla Torr. & Frem.: Pinaceae) trees growing at two different locations. Total monoterpene content was highest in the fresh needles (mean=5.6 ± 2.2 mg/g extracted air dry weight), but also remained relatively high in senescent needles (mean=3.6 ±1.8 mg/g extracted air dry weight), either still attached to the tree or forming the freshest layer of understory litter. Decaying needles within a dark decomposing layer of litter material 5-20 cm from the surface were found to contain much lower amounts of total monoterpenes (average: =0.12 ±0.06 mg/g extracted air dry weight). Further investigation of the fate of these compounds in the pinyon understory is required to determine if these hydrocarbons are indeed exerting phytotoxic characteristics.

    We compared self-reported dietary intake from the very remote sample of the National Aboriginal and Torres Strait Islander Nutrition and Physical Activity Survey (VR-NATSINPAS; n=1,363) to one year of food and beverage purchases from 20 very remote Indigenous Australian communities (servicing ∼8,500 individuals). Differences in food (% energy from food groups) and nutrients were analysed using t-test with unequal variance. Per-capita energy estimates were not significantly different between the surveys (899 MJ/person/day [95% confidence interval -152,1950] p=0.094). Self-reported intakes of sugar, cereal products/dishes, beverages, fats/oils, milk products/dishes and confectionery were significantly lower than that purchased, while intakes of meat, vegetables, cereal-based dishes, fish, fruit and eggs were significantly higher (pfood and nutrient availability in this population longitudinally; however, further evidence is needed on approaches to estimate wastage and foods sourced outside the store. There is potential for these data to complement each other to inform nutrition policies and programs in this population. © 2017 Menzies School of Health Research.

    This work tries to describe the nutrient demands of six different, very fast-growing clones of the species Populus trichocarpa Torr. Et. Grey. Relevant are the capability for taking up different nutrients, and the plants' efficiency in using these nutrients for vapour exchange of the leaves (photosynthesis, respiration in the dark, transpiration) as well as for increasing biomass. A further aim pursued with these measurements is the attempt to explain the different growth of these six popular clones. Here, field experiments have shown a gradiation of the clones' growth performance. From the first to the sixth clone, growth performance declines steadily. Should there be differences among the clones as to the physiological, biometric and phenological variables to be investigated, then this work might lead to the identification of growth-determining factors suitable for postulating of the investigated clones.

  10. Depletion of the vibrational ground state of CH4 in absorption spectroscopy at 3.4 μm in N2 and air in the 1-100 Torr range

    A model presented in an accompanying work predicts that mid-IR absorption signals from methane in trace concentrations in various buffer gases detected at pressures in the 1-100 Torr range can be reduced and distorted due to depletion of the vibrational ground state if the molecules are exposed to laser powers in the tens of mW range or above. This work provides experimental evidence of such depletion in a resonant cavity under a variety of conditions, e.g. for intracavity laser powers up to 2 W and for buffer gases of N2 or dry air, and verifies the applicability of the model. It was found that the degree of depletion is significantly larger in N2 than dry air, and that it increases with pressure for pressures up to around 10 Torr (attributed to a decreased diffusion rate) but decreases with pressure for pressures above 20 Torr (caused by an increased collisional vibrational decay rate). The maximum degree of depletion (∼80%) was obtained for methane in N2 at around 15 Torr. This implies that absorption spectrometry of methane can experience significant non-linear dependencies on laser power, pressure, as well as buffer gas composition. It is shown that depletion takes place also in 13CH4, which verifies the applicability of the model also for this isotopologue, and that NICE-OHMS signals detected in absorption phase are less affected by depletion than in dispersion. It was concluded that the absorption mode of detection can provide concentration assessments that are virtually free of influence of depletion for intracavity powers below 0.8 W.

    2009-01-01

    Greenhouse experiments were undertaken to identify soil factors that curtail growth of the exotic annual grass Bromus tectorum L. (cheatgrass) without significantly inhibiting growth of native perennial grasses (here represented by Hilaria jamesii [Torr.] Benth). We grew B. tectorum and H. jamesii alone (monoculture pots) and together (combination pots) in soil treatments that manipulated levels of soil phosphorus, potassium, and sodium. Hilaria jamesii showed no decline when its aboveground biomass in any of the applied treatments was compared to the control in either the monoculture or combination pots. Monoculture pots of B. tectorum showed a decline in aboveground biomass with the addition of Na2HPO4 and K2HPO4. Interestingly, in pots where H. jamesii was present, the negative effect of these treatments was ameliorated. Whereas the presence of B. tectorum generally decreased the aboveground biomass of H. jamesii (comparing aboveground biomass in monoculture versus combination pots), the presence of H. jamesii resulted in an enhancement of B. tectorum aboveground biomass by up to 900%. We hypothesize that B. tectorum was able to obtain resources from H. jamesii, an action that benefited B. tectorum while generally harming H. jamesii. Possible ways resources may be gained by B. tectorum from native perennial grasses include (1) B. tectorum is protected from salt stress by native plants or associated soil biota; (2) when B. tectorum is grown with H. jamesii, the native soil biota is altered in a way that favors B. tectorum growth, including B. tectorum tapping into the mycorrhizal network of native plants and obtaining resources from them; (3) B. tectorum can take advantage of root exudates from native plants, including water and nutrients released by natives via hydraulic redistribution; and (4) B. tectorum is able to utilize some combination of the above mechanisms. In summary, land managers may find adding soil treatments can temporarily suppress B. tectorum

This small outcrop contains a fairly rich record of fruits and seeds, among which about 50 species were identified; the most frequent invariably belong to submerged, floating and emergent aquatic herbs, possibly because these were buried not far from their place of growth, thus representing the ancient local vegetation.  The fruits and seeds of woody plants, including several exotic elements, were transported from neighbouring areas and indicate a paleoclimate similar to the present day, though slightly wetter.  Among molluscs, three distinct assemblages were found, indicating fluvial, swampy and lacustrine environment, respectively.  They contain taxa of biochronological interest, most of them typical of Early Pleistocene deposits (late Villafranchian, but making their first appearance in the Late Pliocene (Middle Villafranchian. One species, Margarifera (Pseudunio auricularia, represents the oldest record everywhere, since it was known, so far, only from the Middle Pleistocene upwards.  As palaeoenvironmental indicators, the ostracods complete the information given by molluscs.  Vetrebrates are represented by large and small mammals, rare birds, reptiles, amphibians and some fishes.  A great number of coprolites was collected as well.  The mammal assemblage shows affinities with the Costa S.

    Full Text Available BackgroundAboriginal and Torres Strait Islander Australians experience a greater burden of disease compared to non-Indigenous Australians. Around one-fifth of the health disparity is caused by cardiovascular disease (CVD. Despite the importance of absolute cardiovascular risk assessment (CVRA as a screening and early intervention tool, few studies have reported its use within the Australian Indigenous primary health care (PHC sector. This study utilizes data from a large-scale quality improvement program to examine variation in documented CVRA as a primary prevention strategy for individuals without prior CVD across four Australian jurisdictions. We also examine the proportion with elevated risk and follow-up actions recorded.MethodsWe undertook cross-sectional analysis of 2,052 client records from 97 PHC centers to assess CVRA in Indigenous adults aged ≥20 years with no recorded chronic disease diagnosis (2012–2014. Multilevel regression was used to quantify the variation in CVRA attributable to health center and client level factors. The main outcome measure was the proportion of eligible adults who had CVRA recorded. Secondary outcomes were the proportion of clients with elevated risk that had follow-up actions recorded.ResultsApproximately 23% (n = 478 of eligible clients had documented CVRA. Almost all assessments (99% were conducted in the Northern Territory. Within this jurisdiction, there was wide variation between centers in the proportion of clients with documented CVRA (median 38%; range 0–86%. Regression analysis showed health center factors accounted for 48% of the variation. Centers with integrated clinical decision support systems were more likely to document CVRA (OR 21.1; 95% CI 5.4–82.4; p < 0.001. Eleven percent (n = 53 of clients were found with moderate/high CVD risk, of whom almost one-third were under 35 years (n = 16.

Zircons from ~16 Ma intrusives and the 12.6 Ma part of the TPIC have remarkably consistent, slightly enriched Hf isotope compositions with ɛHf(i) of -1 to +2. An abrupt shift towards more juvenile Hf isotope compositions is observed in the ~12.45 Ma part of the TPIC, with ɛHf(i) of +3 to +6. Bulk rock Nd and Sr isotopes for the TPIC show the same shift towards more juvenile compositions at this time1. The long-term consistency of ɛHf(i) from 16 to 12.6 Ma is surprising, given that in the same period the bulk rock chemistry changes from calc-alkaline to transitional alkaline. Conversely, the major shift in ɛHf(i) is not correlated with any change in bulk rock chemistry, which remains transitional alkaline from 12.6 to 12.45 Ma. The decoupling of major element chemical evolution and Hf isotope signatures suggests that the subsequent rapid influx of juvenile material recorded by our Hf isotope data must have occurred by renewed mantle melting. Subduction of the Chile ridge at ~12.5 Ma in this area caused arc magmatism to move westwards and back-arc extension to initiate. We propose that the first TPIC magmas (12.6 Ma) came from a mantle wedge with a residual subduction signature. Subsequent melting of more juvenile mantle, less contaminated by a subduction component, generated the 12.45 Ma TPIC magmas. These results demonstrate that magmatic complexes such as the TPIC may tap distinct mantle sources even on very short timescales, fingerprinting arc-backarc transition processes. 1Leuthold et al., 2013, JPET, 54: 273-303 2Leuthold et al., 2012, EPSL, 325: 85-92

    In the framework of a Singular Strategic Project entitled: Advanced Technologies of Carbon, Capture and Storage (CCS)1', supported by the MICINN (Spain) and the FEDER founds (EU), specifically in the Carbon Storage Task, a comprehensive study on the CO{sub 2} leakage as DIG (Dissolved Inorganic Carbon) in the Alicun de Las Torres (Prov. of Granada) natural analogue thermal system was envisaged. This analogous system is characterised by the presence of a very important travertine formation, which can be considered as a permanent and stable sink for CO{sub 2}. Consequently, the estimation of the travertine mass has been a main objective of this investigation. For that, data from two complementary electrical tomography campaigns, previously treated by a powerful geostatistical tool, have been used, as well as the porosity average value of this travertine and the calcite density. Besides this, the statistical methodology applied has also allowed the establishment of a 3-D model of the travertine formation, displaying the geological contact between this formation and the underlying materials, as well as the contacts among the three units forming the travertine formation.

    Full Text Available RESUMEN El presente artículo trata de explicar, con el ejemplo de los hallazgos en la Restauración de la Torre de San Juan Bautista de Écija, la dificultad de establecer límites precisos entre Restauración-Rehabilitación-Intervención. También se señala el conocimiento de la historia, la importancia de la intuición y el rigor del dibujo como herramientas del proyecto. Se analiza e indaga muy someramente sobre el concepto de torre desde sus proporciones y formas hasta conceptos más abstractos como comunicación y poder y se pone de manifiesto que el desconocido espacio interior de la torre, tiene igual valor o más que el que se reconoce en el concepto primario de su término. Con todo esto, se quiere demostrar que con las pequeñas decisiones del proyecto una vez ejecutadas, se consigue dar a la obra un valor nuevo y enfatizar en ella la idea original que la construye. SUMMARY This article aims to explain, with the example of the finds in the Restoration of the Tower of St. John the Baptist Church in Écija, the difficulty of establishing exact boundaries between Restoration-Rehabilitation-Intervention. Also, the knowledge of history, the importance of intuition and rigor in design are pointed out as tools of the project. It analyzes and very briefly explores the tower concept from its proportions and shapes to more abstract concepts such as communication and power, and shows that the unknown interior of the tower is of equal or greater value than that recognized in the primary concept of its conclusion. With all of this it is hoped to demonstrate that the small decisions of the project, once implemented, will give the work new value and emphasize the original idea that built it.

    Full Text Available Abstract Background In Australia, ‘Alcohol Management Plans’ (AMPs provide the policy infrastructure for State and Commonwealth Governments to address problematic alcohol use among Aboriginal and Torres Strait Islanders. We report community residents’ experiences of AMPs in 10 of Queensland’s 15 remote Indigenous communities. Methods This cross-sectional study used a two-stage sampling strategy: N = 1211; 588 (48% males, 623 (52% females aged ≥18 years in 10 communities. Seven propositions about ‘favourable’ impacts and seven about ‘unfavourable’ impacts were developed from semi-structured interviews. For each proposition, one-sample tests of proportions examined participant agreement and multivariable binary logistic regressions assessed influences of gender, age (18–24, 25–44, 45–64, ≥65 years, residence (≥6 years, current drinking and Indigenous status. Confirmatory factor analyses estimated scale reliability (ρ, item loadings and covariances. Results Slim majorities agreed that: AMPs reduced violence (53%, p = 0.024; community a better place to live (54%, 0.012; and children were safer (56%, p < 0.001. More agreed that: school attendance improved (66%, p < 0.001; and awareness of alcohol’s harms increased (71%, p < 0.001. Participants were equivocal about improved personal safety (53%, p = 0.097 and reduced violence against women (49%, p = 0.362. The seven ‘favourable’ items reliably summarized participants’ experiences of reduced violence and improved community amenity (ρ = 0.90. Stronger agreement was found for six ‘unfavourable’ items: alcohol availability not reduced (58%, p < 0.001; drinking not reduced (56%, p < 0.001; cannabis use increased (69%, p < 0.001; more binge drinking (73%, p < 0.001; discrimination experienced (77%, p < 0.001; increased fines, convictions and criminal records for breaching restrictions (90%, p < 0

Armani, e, sob coorientação da mestranda do Programa de Pós-graduação em História – UFSM Jóice Anne A. Carvalho. Busca-se traçar uma linha teórica referente à constituição da Nação e o papel do indivíduo mergulhado na coletividade, ou seja, quem compõe e quem não compõe a estrutura social do Brasil na construção do eu nacional. Ao longo do século XIX e início do século XX, pensadores de várias áreas das ciências começaram a se questionar sobre as diferenças dos seres humanos e que, mais tarde, desembocariam num discurso hierárquico de raças. Essas menções à suposta inferioridade da raça brasileira fez com que Alberto Torres, assumisse uma posição contrária a esse discurso, expondo-a no livro “O Problema Nacional Brasileiro” (1914. Sua teoria sobre as raças afirmava que a única questão que podia vir a contribuir para certa diferenciação racial seriam os fatores mesológicos de uma Nação, mais precisamente, o clima. Nesta mesma linha de pensamento, o autor Monteiro Lobato também analisa a composição da população brasileira e a discussão acerca da hierarquização racial tão em voga no período. Em seu livro “Problema Vital” (1918, nega a afirmação de inferioridade da raça brasileira e aponta as medidas que o Estado deveria tomar para que a população conseguisse atingir o progresso. Lobato também acaba resgatando a figura do caboclo, numa clara tendência de traçar um perfil para o brasileiro

In Australia, Aboriginal and Torres Strait Islander children and young people are 9 times more likely to be placed in care than non-Aboriginal young people (Australian Institute of Health and Welfare, 2015. Australia’s history of colonization and subsequent policies have caused trauma to individuals, families, and communities and resulted in poor physical and mental health and mistrust of services. This review was undertaken to identify programs and policies currently in place that aim to improve the mental health and well-being of this vulnerable population. It provides an analysis of both the strengths of the current system as well as what has been inadequately addressed based on literature in the area.By incorporating an Aboriginal perspective, this review focuses on social, emotional, and spiritual well-being (SESWB and the aspects of a child’s life and community that promote this. A realist review of the academic and grey literature was conducted in 2014. It included an extensive search of government and non-government (NGO publications. The review identified nine programs or policies that are designed to improve the SESWB of Aboriginal young people in OoHC in local and international settings. These are the Aboriginal and Torres Strait Islander Child Placement Principle, cultural support plans, Aboriginal Community Controlled Organisations (ACCOs, family group decision-making, therapeutic care, and Panyappi Mentoring Program. Given that culturally competent service provision is important to SESWB, the review concludes that an increase in monitoring and evaluation is necessary to determine the effectiveness of programs and ensure their implementation and sustainability when warranted. Policy and research work is needed to adapt and devise programs promoting the SESWB of Aboriginal young people (at both the

Le raccomandazioni sull’ “Historic Urban Landscape”, e gli strumenti operativi promossi dall’ICOMOS “Guidance on Heritage Impact Assessments for Cultural World Heritage Properties” del 2011, si configurano come le più recenti disposizioni concernenti la conservazione, protezione e valorizzazione del patrimonio culturale (Fusco Girard, 2010. La Guida ICOMOS è stata considerata lo strumento più adatto per valutare gli impatti dei grandi progetti di riqualificazione dei waterfront urbani sul patrimonio culturale. Per comprendere al meglio tale strumento è stata fatta un’applicazione per valutare gli impatti del Grande Progetto Pompei sul waterfront di Torre Annunziata, città costiera nel Golfo di Napoli sito UNESCO. A questa fase di analisi segue una riflessione su come migliorare l’Heritage Impact Assessment, come strumento capace di valutare non soltanto gli impatti culturali ma anche quelli economici, per parlare di “economia del patrimonio culturale”. La proposta ultima è quella di affiancare al processo di “Heritage Impact Assessment” una valutazione degli impatti economici, attraverso un’analisi costi-benefici, per quantificare in termini monetari la convenienza degli investimenti nella conservazione del patrimonio storico urbano delle città costiere, proponendo una “Economic Heritage Impact Assessment” (EHIA. Tale metodo, elaborato dall’autrice all’interno della tesi di dottorato “Il paesaggio storico urbano delle città costiere: sfide e opportunità.

    Phytoremediation is potentially effective for managing excessive selenium (Se) in drainage sediment residing in the San Luis Drain in central California. This 2-year field study examined the feasibility of amending drainage sediment (containing 4.78 μg Se g -1 ) with methionine and casein to enhance volatilization without or with vegetation of Sporobolus airoides. Results show that without organic amendments, rates of Se volatilization were less than 25 μg m -2 d -1 in all plots. After amending the sediment with 71.4 mg methionine kg -1 soil, Se volatilization rates were 434 ± 107 μg m -2 d -1 in vegetated plots and 289 ± 117 μg m -2 d -1 in irrigated bare plots. With the amendment of 572 mg casein kg -1 soil, rates increased to 346 ± 103 μg m -2 d -1 in irrigated bare plots and to 114 ± 55 μg m -2 d -1 in vegetated plots.

    Full Text Available Abstract Background Disparities in health status occur between people with differing socioeconomic status and disadvantaged groups usually have the highest risk exposure and the worst health outcome. We sought to examine the social disparities in the population prevalence of diabetes and in the development of treated end stage renal disease due to type 1 diabetes which has not previously been studied in Australia and New Zealand in isolation from type 2 diabetes. Methods This observational study examined the population prevalence of diabetes in a sample of the Australian population (7,434,492 using data from the National Diabetes Services Scheme and of treated end stage renal disease due to diabetes using data from the Australian and New Zealand Dialysis and Transplant Registry. The data were then correlated with the Australian Bureau of Statistics Socioeconomic Indexes for Areas for an examination of socioeconomic disparities. Results There is a social gradient in the prevalence of diabetes in Australia with disease incidence decreasing incrementally with increasing affluence (Spearman’s rho = .765 p < 0.001. There is a higher risk of developing end stage renal disease due to type 1 diabetes for males with low socioeconomic status (RR 1.20; CI 1.002–1.459 in comparison to females with low socioeconomic status. In Australia and New Zealand Aboriginal and Torres Strait Islanders, Maori and Pacific Islanders appear to have a low risk of end stage renal disease due to type 1 diabetes but continue to carry a vastly disproportionate burden of end stage renal disease due to type 2 diabetes (RR 6.57 CI 6.04–7.14 & 6.48 CI 6.02–6.97 respectively p < 0.001 in comparison to other Australian and New Zealanders.

There is a higher risk of developing end stage renal disease due to type 1 diabetes for males with low socioeconomic status (RR 1.20; CI 1.002-1.459) in comparison to females with low socioeconomic status. In Australia and New Zealand Aboriginal and Torres Strait Islanders, Maori and Pacific Islanders appear to have a low risk of end stage renal disease due to type 1 diabetes but continue to carry a vastly disproportionate burden of end stage renal disease due to type 2 diabetes (RR 6.57 CI 6.04-7.14 & 6.48 CI 6.02-6.97 respectively p < 0.001) in comparison to other Australian and New Zealanders. Whilst low socioeconomic status is associated with a higher prevalence of diabetes the inverse social gradient seen in this study has not previously been reported.

    The revegetation work begun in 1970 at Cyprus Pima Mine, an open pit copper mine south-west of Tucson, Arizona, was evaluated to determine the effects of slope aspect and mining waste material on plant survival and growth. Only one shrub, Dodonea viscosa (L.) Jacq. (hopbush), survived on the east slope. Baccharis sarothroides Gray (desert broom) was prolific on the north aspect. Cerdicium microphyllum Torr. (palo verde) survived best on the east slope and Nicotiana glauca Grah. (desert tobacco) survived only on the north slope. The survival of the other tree species was not affected by slope aspect. Slope exposure did not affect tree size, except for Eucalyptus microtheca Muell. (tiny capsule eucalyptus) which grew larger on the north slope. E. rostrata Schlechtend (red gum eucalyptus) grew taller in overburden than in tailing on the east slope. Differences in soil material within each slope exposure did not significantly affect growth of the other tree species. In semi-arid regions, such as south-western Arizona, even slight differences in available moisture may determine the survival of a plant species in the area. (Refs. 11).

    Introduction Empirical evidence on family and community risk and protective factors influencing the comparatively high rates of potentially preventable hospitalisations and deaths among Aboriginal and Torres Strait Islander infants and children is limited. As is evidence on geographical variation in these risks. The ‘Defying the Odds’ study aims to explore the impact of perinatal outcomes, maternal social and health outcomes and level of culturally secure service availability on the health outcomes of Western Australian (WA) Aboriginal infants and children aged 0–5 years. Methods and analysis The study combines a retrospective cohort study that uses state-wide linked health and administrative data from 12 data sources for multiple generations within Aboriginal families in WA, with specifically collected survey data from health and social services supporting Aboriginal families in regions of WA. Data sources include perinatal/birth registration, hospital, emergency department, mental health services, drug and alcohol service use, mortality, infectious disease notifications, and child protection and family services. Multilevel regression models will be used to examine the intensity of admissions and presentations, mortality, intensity of long stays and morbidity-free survival (no admissions) for Aboriginal children born in WA in 2000–2013. Relationships between maternal (and grand-maternal) health and social factors and child health outcomes will be quantified. Community-level variation in outcomes for Aboriginal children and factors contributing to this variation will be examined, including the availability of culturally secure services. Online surveys were sent to staff members at relevant services to explore the scope, reach and cultural security of services available to support Aboriginal families across selected regions of WA. Ethics and dissemination Ethics approvals have been granted for the study. Interpretation and dissemination are guided by the

    Aboriginal and Torres Strait Islander peoples in Australia have been found to have poorer cancer survival than non-Aboriginal people. However, use of conventional relative survival analyses is limited due to a lack of life tables. This cohort study examined whether poorer survival persist after accounting for competing risks of death from other causes and disparities in cancer stage at diagnosis, for all cancers collectively and by cancer site. People diagnosed in 2000-2008 were extracted from the population-based New South Wales Cancer Registry. Aboriginal status was multiply imputed for people with missing information (12.9%). Logistic regression models were used to compute odds ratios (ORs) with 95% confidence intervals (CIs) for 'advanced stage' at diagnosis (separately for distant and distant/regional stage). Survival was examined using competing risk regression to compute subhazard ratios (SHRs) with 95%CIs. Of the 301,356 cases, 2517 (0.84%) identified as Aboriginal (0.94% after imputation). After adjusting for age, sex, year of diagnosis, socio-economic status, remoteness, and cancer site Aboriginal peoples were more likely to be diagnosed with distant (OR 1.30, 95%CI 1.17-1.44) or distant/regional stage (OR 1.29, 95%CI 1.18-1.40) for all cancers collectively. This applied to cancers of the female breast, uterus, prostate, kidney, others (those not included in other categories) and cervix (when analyses were restricted to cases with known stages/known Aboriginal status). Aboriginal peoples had a higher hazard of death than non-Aboriginal people after accounting for competing risks from other causes of death, socio-demographic factors, stage and cancer site (SHR 1.40, 95%CI 1.31-1.50 for all cancers collectively). Consistent results applied to colorectal, lung, breast, prostate and other cancers. Aboriginal peoples with cancer have an elevated hazard of cancer death compared with non-Aboriginal people, after accounting for more advanced stage and competing

    Relatively little is known about how depression amongst people with chronic illness is identified and managed in diverse primary health care settings. We evaluated the role of complex physical needs in influencing current practice of depression screening, documentation and antidepressant prescriptions during a 12-month period, among adults with Type 2 diabetes attending Aboriginal and Torres Strait Islander primary care health centres in Australia. We analysed clinical audit data from 44 health centres participating in a continuous quality improvement initiative, using previously reported standard sampling and data extraction protocols. Eligible patients were those with Type 2 diabetes with health centre attendance within the past 12 months. We compared current practice in depression screening, documentation and antidepressant prescription between patients with different disease severity and co-morbidity. We used random effects multiple logistic regression models to adjust for potential confounders and for clustering by health centre. Among the 1174 patients with diabetes included, median time since diagnosis was 7 years, 19% of patients had a co-existing diagnosis of Ischaemic Heart Disease and 1/3 had renal disease. Some 70% of patients had HbAc1>7.0%; 65% had cholesterol >4.0 mmol1-1 and 64% had blood pressure>130/80 mmHg. Documentation of screening for depression and of diagnosed depression were low overall (5% and 6% respectively) and lower for patients with renal disease (Adjusted odds ratio [AOR] 0.21; 95% confidence interval [CI] 0.14 to 0.31 and AOR 0.34; 95% CI 0.15 to 0.75), and for those with poorly controlled disease (HbA1c>7.00 (AOR 0.40; 95% CI 0.23 to 0.68 and AOR 0.51; 95% CI 0.30 to 84)). Screening for depression was lower for those on pharmaceutical treatment for glycaemic control compared to those not on such treatment. Antidepressant prescription was not associated with level of diabetes control or disease severity. Background levels of

    Duckweed(Lemna perpusilla Torr.) was used as experimental materials and several physiological responses of Lemna perpusilla Torr.,such as biomass growth,pigment contents,adsorption characteristics of heavy metals,nitrogen and phosphorus,to elevated concentrations of Pb(Ⅱ)(up to 40 mg/L) and Cu(Ⅱ)(up to 4 mg/L) were investigated.The results showed that high metal concentration might inhibit the growth of Lemna perpusilla Torr.Copper was found to be more toxic to plants than lead.It was demonstrated that exposure to high concentrations of lead and copper results in the high bioaccumulation of metals in Lemna perpusilla Torr.(26.09 mg/g of Pb in the plant grown in water with 40 mg/L Pb(Ⅱ) and 2.49 mg/g of Cu in the plant grown in water with 4 mg/L Cu(Ⅱ)).At these levels the plant growth was significantly inhibited and the plant pigment content significantly decreased.Also,a significant release of P and N was observed at these high levels of metal stress.The results of this study confirm that Lemna perpusilla Torr.is a suitable candidate for the phytoremediation in low-level lead-contaminated water bodies.%以青萍种浮萍(Lemna perpusilla Torr.)为实验材料,以Pb(Ⅱ)、Cu(Ⅱ)为染毒因子,设定金属离子浓度梯度(Pb(Ⅱ):0~40 mg/L,Cu(Ⅱ):0~4 mg/L),考察了在不同金属离子浓度下青萍生长状况、叶片色素含量以及金属离子浓度对青萍N、P和金属离子吸收能力的影响。结果表明:金属离子浓度的越高,青萍生长受抑制越严重;Cu(Ⅱ)对青萍的毒害大于Pb(Ⅱ);在Pb(Ⅱ)浓度为40 mg/L,Cu(Ⅱ)浓度为4 mg/L时,青萍对Pb(Ⅱ)和Cu(Ⅱ)的平均单位鲜重富集量分别为26.09 mg/g和2.49 mg/g,但同时,青萍的生长受到严重抑制,叶绿素含量急剧下降,且N、P从细胞中溶出。研究表明,青萍比较适宜修复被低浓度Pb(Ⅱ)污染的水体。

    Full Text Available Purpose: The aim of the current study is to use the Ivory Tower metaphor to discuss and question the false dichotomy between theory and practice, as well as the insufficient pragmatic and performative solution towards the market logic, and to problematize the concept of praxis as a possibility through critical approaches. Originality/gap/relevance/implications: 1. the Ivory Tower demonstrates the existence of a gap in the relation between theory and practice; 2. the essay is conducted according to critical approaches; 3. the Critical Theory has the potential to deconstruct the assigned and socially constructed meanings of the Ivory Tower. Key methodological aspects: This is a theoretical essay that dialectically explores the Ivory Tower metaphor. Summary of key results: 1. the organizational science linked to the instrumental logic makes no place for praxis; 2. the Traditional Theory does not allow thinking about the relation between theory and practice through praxis, because it polarizes such categories and gives primacy to practice by demanding performance and productivity from theory; 3. based on the Ivory Tower metaphor, it is necessary to make criticisms for the sake of praxis and not for the sake of the practice understood just as technical and instrumental utility. Key considerations/conclusions: We pursuit solutions to remove the dichotomies that take the dialectical nature away from reality; it is necessary (reconstructing new ways to get in and out of the tower on behalf of emancipation, in the permanent and inseparable relation between theory and practice.

    Treatment guidelines recommend watchful waiting for children older than 2 years with acute otitis media (AOM) without perforation, unless they are at high risk of complications. The high prevalence of chronic suppurative otitis media (CSOM) in remote Aboriginal and Torres Strait Islander communities leads these children to be classified as high risk. Urban Aboriginal and Torres Strait Islander children are at lower risk of complications, but evidence to support the subsequent recommendation for watchful waiting in this population is lacking. This non-inferiority multi-centre randomised controlled trial will determine whether watchful waiting is non-inferior to immediate antibiotics for urban Aboriginal and Torres Strait Islander children with AOM without perforation. Children aged 2 - 16 years with AOM who are considered at low risk for complications will be recruited from six participating urban primary health care services across Australia. We will obtain informed consent from each participant or their guardian. The primary outcome is clinical resolution on day 7 (no pain, no fever of at least 38 °C, no bulging eardrum and no complications of AOM such as perforation or mastoiditis) as assessed by general practitioners or nurse practitioners. Participants and outcome assessors will not be blinded to treatment. With a sample size of 198 children in each arm, we have 80 % power to detect a non-inferiority margin of up to 10 % at a significance level of 5 %, assuming clinical improvement of at least 80 % in both groups. Allowing for a 20 % dropout rate, we aim to recruit 495 children. We will analyse both by intention-to-treat and per protocol. We will assess the cost- effectiveness of watchful waiting compared to immediate antibiotic prescription. We will also report on the implementation of the trial from the perspectives of parents/carers, health professionals and researchers. The trial will provide evidence for the safety and effectiveness of watchful waiting

    The subduction system in southern Patagonia provides direct evidence for the variability of the position of an active continental arc with respect to the subducting plate through time, but the consequences on the arc magmatic record are less well studied. Here we present a geochemical and geochronological study on small plutons and dykes from the upper crust of the southern Patagonian Andes at 51°S, which formed as a result of the subduction of the Nazca and Antarctic plates beneath the South American continent. In situ U-Pb geochronology on zircons and bulk rock geochemical data of plutonic and dyke rocks are used to constrain the magmatic evolution of the retro-arc over the last 30 Ma. We demonstrate that these combined U-Pb and geochemical data for magmatic rocks track the temporal and spatial migration of the active arc, and associated retro-arc magmatism. Our dataset indicates that the rear-arc area is characterized by small volumes of alkaline basaltic magmas at 29-30 Ma that are characterized by low La/Nb and Th/Nb ratios with negligible arc signatures. Subsequent progressive eastward migration of the active arc culminated with the emplacement of calc-alkaline plutons and dikes 17-16 Ma with elevated La/Nb and Th/Nb ratios and typical subduction signatures constraining the easternmost position of the southern Patagonian batholith at that time. Geochemical data on the post-16 Ma igneous rocks including the Torres del Paine laccolith indicate an evolution to transitional K-rich calc-alkaline magmatism at 12.5 ± 0.2 Ma. We show that trace element ratios such as Nb/Ta and Dy/Yb systematically decrease with increasing SiO2, for both the 17-16 Ma calc-alkaline and the 12-13 Ma K-rich transitional magmatism. In contrast, Th/Nb and La/Nb monitor the changes in the source composition of these magmas. We suggest that the transition from the common calc-alkaline to K-rich transitional magmatism involves a change in the source component, while the trace element ratios

    Full Text Available The Torre del Oro is a Moslem building of three bodies dating from the 13th Century. The second and third bodies are built with bricks. According to mineralogical analysis two main groups of bricks can be established. A first group of bricks contents illite and low amounts of gehlenite and wollastonite. They are reddish and present a mycrocristalline matrix. The firing temperature ranges between 800-850ºC for this group. Firing temperatures for the second group ranged between 850-900ºC, because of the absence of illite, and the presence of important amounts of gehlenite and wollastonite-diopside. They are yellowish and present a green coloured isotropic matrix. Mineralogical compositions of laboratory firing samples at 800ºC and 900ºC agree reasonably with the estimated firing temperature. Chemical composition presents no differences among the samples, being quite similar to Tertiary sediments from the Ecija Formation (blue marls and the Transition Series (silts. These materials crop out quite near Seville, and have been traditionally used in the local tile industry.

    La Torre del Oro es un edificio almohade del siglo XIII de tres cuerpos, con fábrica de ladrillo en el segundo y tercer cuerpo. De acuerdo con el análisis mineralógico se han diferenciado dos grupos de ladrillos. El primero se caracteriza por la presencia de illita y el desarrollo incipiente o nulo de fases de alta temperatura (gehlenita, wollastonita. Presentan coloraciones rojizas y pasta con textura microcristalina. Estos ladrillos se cocieron entre 800-850ºC. Para el segundo grupo la temperatura de cocción se encuentra entre 850-900ºC, según se deduce de la ausencia de illita y de la presencia en cantidades importantes de gehlenita y wollastonita-diopsido. La pasta es verde oscura e isótropa, presentando los ladrillos colores claros. El estudio de la evolución de las fases en los ladrillos calentados en el laboratorio a 800 y 900ºC concuerda razonablemente

    The rate constant of the reaction Cl + CF(3)CF═CH(2) (k(1)) has been measured relative to several reference species using the relative rate technique with either gas chromatographic analysis with flame-ionization detection (GC/FID) or Fourier transform infrared (FTIR) analysis. Cl atoms were generated by UV irradiation of Cl(2)/CF(3)CF═CH(2)/reference/N(2)/O(2) mixtures. At 300-400 K in the presence of >20 Torr O(2), k(1) = 1.2 × 10(-11) e((+1100/RT)) cm(3) molecule(-1) s(-1). In N(2) diluent, k(1) has a sharp negative temperature coefficient resulting from the relatively small exothermicity of the following reactions: (1a) Cl + CF(3)CF═CH(2) ↔ CF(3)CFClCH(2)(•); (1b) Cl + CF(3)CF═CH(2) ↔ CF(3)CF(•)CH(2)Cl (reaction 1), which were determined in these experiments to be ∼16.5 (±2.0) kcal mol(-1). This low exothermicity causes reaction 1 to become significantly reversible even at ambient temperature. The rate constant ratio for the reaction of the chloroalkyl radicals formed in reaction 1 with Cl(2) (k(2)) or O(2) (k(3)) was measured to be k(2)/k(3) = 0.4 e(-(3000/RT)) for 300-400 K. At 300 K, k(2)/k(3) = 0.0026. The reversibility of reaction 1 combined with the small value of k(2)/k(3) leads to a sensitive dependence of k(1) on the O(2) concentration. Products measured by GC/FID as a function of temperature are CF(3)CFClCH(2)Cl, CF(3)COF, and CH(2)Cl(2). The mechanism leading to these products is discussed. The rate constant for the reaction Cl + CF(3)CFClCH(2)Cl (k(11)) was measured as a function of temperature (300-462 K) at 760 Torr to be k(11) = 8.2 × 10(-12) e(-(4065/RT)) cm(3) molecule(-1) s(-1). Rate constants relative to CH(4) for the reactions of Cl with the reference compounds CH(3)Cl, CH(2)Cl(2), and CHCl(3) were measured at 470 K to resolve a literature discrepancy. (R = 1.986 cal K(-1) mol(-1)).

    Full Text Available El cuerpo humano no es solamente una entidad biológica regida por leyes naturales, ni simplemente el conjunto de órganos y huesos que lo constituyen. De forma fundamental, los cuerpos son, a la vez, contenedores de percepciones y significados, un medio de expresión y un lugar de intervención, control y domesticación. Es en ellos donde saberes, culturas y poderes confluyen y se expresan. Así lo han entendido un gran número de trabajos que desde las ciencias sociales han convertido al cuerpo humano en campo privilegiado de estudio. Hace ya casi 20 años que el historiador de la medicina Roy Porter señalaba las enormes oportunidades analíticas e interpretativas que el estudio del cuerpo ofrecía. Porter destacaba el necesario carácter interdisciplinario que implicaba este nuevo objeto de análisis y algunos de los campos potenciales para su estudio histórico: el cuerpo como condición humana; la forma del cuerpo; la anatomía del cuerpo; cuerpo, mente y alma; sexo y género; el cuerpo y la política del cuerpo; el cuerpo, la civilización y sus insatisfacciones. Desde que Porter escribiera su artículo “History of the Body” en un libro que intentaba aportar nuevas perspectivas para la escritura de la historia, los trabajos sobre este tema se han multiplicado, corroborando sus potencialidades y consolidando el cuerpo humano como objeto de estudio interdisciplinario. La historia de la ciencia y la medicina, la antropología, la historia cultural, los estudios de género y la sociología son solo algunas de las disciplinas que han aportado perspectivas teóricas y metodológicas para aproximarse al cuerpo humano como una construcción sociocultural, y que, a través de prácticas, discursos, imaginarios y representaciones, permiten que esa construcción tome forma y opere en el mundo social.

    Results of a study of the content of radium-226 in plants growing on inactive uranium mill tailings sites in the Four Corners Region of the southwestern United States and in plants grown under greenhouse conditions with minimal surficial contamination are reported. Field plant samples and associated substrates were analyzed from two carbonate tailings sites in the Grants Mineral Belt of New Mexico. Radium activities in air-cleaned samples ranged from 5 to 368 pCi/g (dry weight) depending on species and location: activities in plants growing on local soils averaged 1.0 pCi/g. The talings and local soils contain 140 to 1400 pCi/g and 2.1 pCi/g, respectively. An evaluation of cleaning methods on selected samples showed that from 17 to 79% of the radium activity measured in air-cleaned samples was due to surficial contamination, which varied with species and location. A survey of 18 inactive uranium mill sites in the Four Corners Region was performed. Radium activity in plant tissues from nine species ranged from 2 to 210 pCi/g on bare tailings and from 0.3 to 30 pCi/g on covered tailings The radium content in most of the soil overburdens on the covered tailings piles was 10 to 17 pCi/g. An experiment was performed to measure radium-226 uptake by two species grown on tailings covered with a shallow (5 cm) soil layer. A grass, Sporobolus airoides (alkali sacaton) and a shrub, Atriplex canescens (four-wing saltbush), were studied. The tailings were a mixture of sands and slimes from a carbonate pile. The tailings treatments were plants grown in a soil cover over tailings; the controls were plants grown only in soil. Three soil types, dune sand, clay loam, and loam, were used. The radium activity of the plant tissue from the tailings treatment compared to that of the appropriate control was 1 to 19 times greater for the grass and 4 to 27 times greater for the shrub

Utilizou-se a técnica de Estudo de Evento para a comparação da diferença na média dos retornos anormais (anteriores e posteriores ao atentado da totalidade da amostra das empresas BVM e AVM. Os resultados obtidos para as três amostras conduziram à conclusão de que não houve geração de retornos anormais após o evento, mas sim uma redução do retorno. Admitiu-se tal conclusão, considerando-se: que o mercado tende a reagir negativamente à ocorrência de informações que prejudiquem a geração de fluxo de caixa das empresas; que a maioria das empresas do setor não vinha divulgando resultados satisfatórios em suas demonstrações financeiras; a desaceleração da economia dos Estados Unidos na época; o "estouro da bolha" Nasdaq em maio de 2001, com indícios de redução do nível de atividade e lucro das empresas norte-americanas; e a crescente aversão de países de origem árabe-muçulmana à política norte-americana para assuntos da região do Golfo Pérsico, o que, em contrapartida, gerava maior exposição de patrimônio norte-americano à ocorrência de atentados.The impact of the September 11th, 2001 terrorist attacks on the twin towers in relation to common stock returns of companies in the US air transport sector was analyzed.

    The Einstein Tower was built in 1921 at the Telegraphsberg in Potsdam with an unique purpose: the empirical demonstration (or refutation of the basis for the Theory of Relativity by Albert Einstein.
    Established already from its origen as a monument that time has consolidated as the icon of an emerging Modernity, the Einstein Tower is at the same time the story of a triple failure: Its explicit objective was never met (concluding results were never arrived at, its location was inadequate (the main observatory was transferred afterwards; first to Lucerne, and later to the Teide mountain, and, on the personal and architectural side, it proved a point of inflection for the career of Erich Mendelsohn, even though it gave him fame and recognition. This article describes this first project not so much as the start of a professional career, but rather as the necessary closure to a path initiated with his war drawings.
    A building almost entirely devoid of openings which springs up from the ground in order to follow the trajectory of an object 150 million kilometers away with its only eye. A scientific program, where human presence is reduced to a minimum (even today in order to protect the sofisticated equipment. The Einstein Tower is above all a fixed telescope mounted on a building. Its biggest contribution, a horizontal spectrographic laboratory halfburied beneath the main vertical support of the tower, is due to its promoter, Professor Erwin Finlay- Freundlich. This astrophysicist knew how to orchestrate an entire media campaign associated to the recent prestige of Albert Einstein, who never worked in the tower (but who did not hesitate to have a picture taken next to it.
    Initially conceived as a mere technical container, the young Mendelsohn soon established that the project for the Einstein Tower, limited in practice to the design of an outer covering shell the interior (there was strongly conditioned to the requirements set by engineers from Carl-Zeiss, should go further and to express its architecture, the theory that tried to demonstrate in the inside. The mass-energy equivalence formulated by Einstein was translated architecturally into a game of mass and light, a balance of movement, in the words of the young architect.
    Rather than expressing it, the tower "represented" movement, reproducing an instant frozen in time. Luise Mendelsohn referred to the works she often visited as the "construction of a ship", and in her dreams she saw it slip away navigating down the hill. Nautical references are not alien to this project: more than a ship, the Einstein tower resembles a surface submarine, with its tower and bow coming out and its body half-buried under a green layer that ripples and folds around it (submarines had been a weapon optimized during the recently finished war.
    The drawings made at the war front by Erich Mendelsohn were populated by vigorous architectures, with expressive gestures, often with an industrial finish. They are autonomous giants, ignorant and independent from their environment, almost nonexistent. Their only tie to their context takes place in the ground; although the Modern Movement proposes a world of prefabricated, light and technological artifacts placed on the ground without making any changes to it, the imaginary architecture by the young Mendelsohn seems to be part of the ground that it comes out of. The Einstein Tower culminates that telluric relationship: its site must not be considered on the urban or even geographic scale; its location is tied to the planet in which it is inserted, and the star at which it gazes, day after day.

    Full Text Available Hereditary nonpolyposis colorectal carcinoma (HNPCC is an autosomal dominant genetic disorder characterized by a predisposition towards colorectal carcinoma and other extracolonic neoplasms. Histiocytic sarcoma (HS is a very rare hematologic neoplasm characterized by a malignant proliferation of cells with histiocytic differentiation. We present the case of a 62-year-old male with previous diagnosis of MTS who presented with metastatic colorectal adenocarcinoma, bilateral papillary renal cell carcinoma, and a new squamous cell carcinoma of the scalp, treated with resection and adjuvant radiation therapy. After reconstructive surgery for his scalp resection, the patient developed a persistent nonhealing skin defect. A punch biopsy of this nonhealing skin defect and subsequent immunohistochemistry revealed neoplastic histiocytic cells restricted to the epidermis and underlying dermis. The diagnosis of cutaneous histiocytic sarcoma was then rendered. Histiocytic sarcoma is an exceptionally rare malignancy. Consequently, there is no universally agreed upon management protocol for this malignancy. The patient was admitted to hospice and treated with palliative radiation. This case demonstrates the need for awareness of the risk of secondary malignancies in cancer patients in order to facilitate early surgical intervention and optimal treatment.

    Covering 130,000 square miles and a wide range of elevations from desert to alpine in Arizona, Utah, Colorado, and New Mexico, the Colorado Plateau has long fascinated researchers. The Colorado Plateau VI provides readers with a plethora of updates and insights into land conservation and management questions currently surrounding the region. The Colorado Plateau VI’s contributors show how new technologies for monitoring, spatial analysis, restoration, and collaboration improve our understanding, management, and conservation of outcomes at the appropriate landscape scale for the Colorado Plateau. The volume’s chapters fall into five major themes: monitoring as a key tool for addressing management challenges, restoration approaches to improving ecosystem condition and function, collaboration and organizational innovations to achieve conservation and management objectives, landscape-scale approaches to understanding, and managing key species and ecological communities. Focusing on the integration of science into resource management issues over the Colorado Plateau, this volume includes contributions from dozens of leading scholars of the region. The Colorado Plateau VI proves a valuable resource to all interested in the conservation management, natural history, and cultural biological resources of the Colorado Plateau.

    2003-12-01

    Full Text Available The present contribution deals with the famous parchment found in 1588 in the old minaret of the former Friday Mosque of Granada, with texts in Arabic, Spanish, and Latin. Together with the Lead Books, discovered in various caves in the outskirts of Granada in the years 1595-1600, the parchment stood at the beginning of an important national cult. After being transferred to the Vatican at the beginning of the seventeenth century and following their anathematization in 1682 the parchment and the Lead Books were kept in Rome until the year 2000 when they were returned to the Archbishopry of Granada. The article presents an analysis of the layout and script of the parchment (2 followed by a survey of translations and transcripts by early (Christian and Muslim eyewitnesses (3.1. The data of these early eyewitnesses are critically compared with the main elements of the parchment (3.2 Then follows a discussion of the palaeographic comments made by a few (Christian and Muslim eyewitnesses (4. In the final conclusions, the authors argue that the document under discussion is indeed the original parchment as found in 1588 notwithstanding the incomprehensibility of its Arabic texts and the many inconsistencies and corruptions of its Spanish and Latin texts (5.1. According to the authors, there is no evidence for the interpretation of the parchment as a pro to-Islamic document, as we are dealing here with a Roman Catholic message heralding the destruction of Islam. At the same time, however, the document also contained a symbolic message, viz. in stipulating that the first-century Granadan Christians, including the well-known figure of Cecilius, wrote Arabic and Spanish, just as many Moriscos did. In other words: even though Islam had to be extirpated, Arabic as a language could harmoniously accompany a genuine Christian life.

    Este artículo está dedicado al famoso pergamino encontrado en 1588 en el antiguo minarete de la que había sido mezquita aljama de Granada, con textos en árabe, latín y castellano. Junto con los libros plúmbeos descubiertos en diversas cuevas a las afueras de la ciudad entre 1595 y 1600, el pergamino está en los orígenes de un importante culto nacional. El artículo presenta un análisis de la composición y escritura del pergamino (2 y pasa revista a las trascripciones y traducciones que se hicieron por testigos cristianos y musulmanes (3.1. Éstas se comparan críticamente con los principales elementos del pergamino (3.2 y se discuten los comentarios paleográfícos hechos por estos testigos contemporáneos (4. Como conclusión, los autores mantienen que el documento transferido desde el Vaticano en el año 2000, es el original encontrado en 1588 a pesar de lo incomprensible de los textos árabes y de la corrupción de los textos castellano y latino (5.1 Según los autores, no hay base para considerar al pergamino como documento proto-islámico, puesto que se trata de un mensaje católico romano anunciando la destrucción del islam. Al mismo tiempo, el documento incluye un mensaje simbólico al mostrar que los cristianos granadinos del siglo I, incluyendo a Cecilius, escribían árabe y castellano, lo mismo que hacían los moriscos. Así, aunque el Islam había de ser extirpado, la lengua árabe se podía armonizar con una vida genuinamente cristiana.

    Full Text Available The WikiLeaks’ founder represents not only a challenge to freedom of information, but also to International Law related to the diplomatic asylum. Julian Assange has been living in the Ecuadorian embassy in London for five years. In the last weeks, news surfaced that Sweden has ceased to request his extradition, the fact that caused much of the case under study. Assange’s situation seems to be diametrically different from Edward Snowden’s; however, both are labeled as "refugees for political reasons". While Assange looks forward to an improvement in his situation in the Ecuadorian embassy in London, Snowden still lives in Russia. Is the diplomatic asylum a usual practice? How to understand the diplomatic asylum in Latin America? What about England? In this paper, the analysis will assume that the concept of asylum is not recognized as a universal practice of International Law. However, in Latin America, it seems to be a usual practice since the judgment of the International Court of Justice on Haya de la Torre’s case.

    The aim of this study was to examine the extent to which antenatal emotional wellbeing (EW) assessments are undertaken in primary health care (PHC) centres and factors associated with completion of EW screening. Medical records of 797 pregnant women from 36 PHC centres in five states (NSW, QLD, SA, WA and NT) were audited. Overall, 85% of the women were Aboriginal. The proportion of women with documented screening for EW varied from 5 to 38% between states (mean 17%). Aboriginal women were four times more likely (adjusted Odds Ratio (OR = 4.13, 95% CI = 2.46-6.92) to not be screened for antenatal EW than non-Aboriginal women. Aboriginality, lack of counselling on financial support were independently linked with no screening of EW. Provision of training for health service providers and further research on appropriate screening tools for Aboriginal women are needed to help redress this gap.

    Aim To understand enablers and barriers influencing postpartum screening for type 2 diabetes following gestational diabetes in Australian Indigenous women and how screening might be improved. Australian Indigenous women with gestational diabetes mellitus (GDM) are less likely than other Australian women to receive postpartum diabetes screening. This is despite a fourfold higher risk of developing type 2 diabetes within eight years postpartum. We conducted interviews with seven Indigenous women with previous GDM, focus groups with 20 Indigenous health workers and workshops with 24 other health professionals. Data collection included brainstorming, visualisation, sorting and prioritising activities. Data were analysed thematically using the Theoretical Domains Framework. Barriers are presented under the headings of 'capability', 'motivation' and 'opportunity'. Enabling strategies are presented under 'intervention' and 'policy' headings. Findings Participants generated 28 enabling environmental, educational and incentive interventions, and service provision, communication, guideline, persuasive and fiscal policies to address barriers to screening and improve postpartum support for women. The highest priorities included providing holistic social support, culturally appropriate resources, improving Indigenous workforce involvement and establishing structured follow-up systems. Understanding Indigenous women's perspectives, developing strategies with health workers and action planning with other health professionals can generate context-relevant feasible strategies to improve postpartum care after GDM. Importantly, we need evidence which can demonstrate whether the strategies are effective.

    Disparities in health perspectives between Indigenous and non-Indigenous populations are major concerns in many of the world's well-developed nations. Indigenous populations are largely less healthy, more prone to chronic diseases, and have an earlier overall mortality than non-Indigenous populations. Low levels of physical activity (PA) contribute to the high levels of disease in Indigenous Australians. Qualitative analysis of structured one-on-one interviews discussing PA in a regional setting. Participants were 12 Indigenous Australian adults, and 12 non-Indigenous Australian adults matched on age, sex, and basketball division. Most participants reported engaging in regular exercise; however, the Indigenous group reported more barriers to PA. These factors included cost, time management and environmental constraints. The physical facilitators identified by our Indigenous sample included social support, intrinsic motivation and role modelling. Findings describe individual and external factors that promote or constraint PA as reported by Indigenous Australian adults. Results indicate that Indigenous people face specific barriers to PA when compared to a non-Indigenous sample. Implications for public health: This study is the first to compare the perspective of Indigenous Australians to a matched group of non-Indigenous Australians and provides useful knowledge to develop public health programs based on culturally sensitive data. © 2017 The Authors.

    To examine the association between residential remoteness and stage of cancer at diagnosis, treatment uptake, and survival within the Australian Indigenous population. Systematic review and matched retrospective cohort study. Australia. Systematic review: published papers that included a comparison of cancer stage at diagnosis, treatment uptake, mortality and/or survival for Indigenous people across remoteness categories were identified (n = 181). Fifteen papers (13 studies) were included in the review. Original analyses: new analyses were conducted using data from the Queensland Indigenous Cancer Study (QICS) comparing cancer stage at diagnosis, treatment uptake, and survival for Indigenous cancer patients living in rural/remote areas (n = 627, 66%) and urban areas (n = 329, 34%). Systematic review: Papers were included if there were related to stage of disease at diagnosis, treatment, mortality and survival of cancer. Restrictions were not placed on the outcome measures reported (e.g. standardised mortality ratios versus crude mortality rates). Original analyses: Odds ratios (OR, 95%CI) were used to compare stage of disease and treatment uptake between the two remoteness groups. Treatment uptake (treated/not treated) was analysed using logistic regression analysis. Survival was analysed using Cox proportional hazards regression. The final multivariate models included stage of cancer at diagnosis and area-level socioeconomic status (SEIFA). Existing evidence of variation in cancer outcomes for Indigenous people in remote compared with metropolitan areas is limited. While no previous studies have reported on differences in cancer stage and treatment uptake by remoteness within the Indigenous population, the available evidence suggests Indigenous cancer patients are less likely to survive their cancer the further they live from urban centres. New analysis of QICS data indicates that Indigenous cancer patients in rural/remote Queensland were less likely to be diagnosed with localised disease and less likely to receive treatment for their cancer compared to their urban counterparts. More research is needed to fully understand geographic differentials in cancer outcomes within the Indigenous population. Knowing how geographical location interacts with Indigenous status can help to identify ways of improving cancer outcomes for Indigenous Australians. © 2015 National Rural Health Alliance Inc.

    To compare the socio-demographic characteristics and type of injury sustained, the use of hospital resources and rates of hospitalisation by injury type, and survival following fall injuries to older Aboriginal people and non-Indigenous Australian people hospitalised for fall-related injuries. Population-based retrospective cohort data linkage study. Setting, participants: New South Wales residents aged 50 years or more admitted to a public or private NSW hospital for a fall-related injury during 1 January 2003 - 31 December 2012. Proportions of patients with defined injury types, mean hospital length of stay (LOS), 30-day mortality, age-standardised hospitalisation rates and age-adjusted rate ratios, 28-day re-admission rates. There were 312 758 fall-related injury hospitalisations for 234 979 individuals; 2660 admissions (0.85%) were of Aboriginal people. The proportion of hospitalisations for fall-related fracture injuries was lower for Aboriginal than for non-Indigenous Australians (49% v 60% of fall-related hospitalisations; P Aboriginal patients was non-fracture injury to head or neck (19% of hospitalisations); for non-Indigenous patients it was hip fractures (18%). Age-adjusted LOS was lower for Aboriginal than for non-Indigenous patients (9.1 v 14.0 days; P Aboriginal people, fall injury hospitalisations increased at an annual rate of 5.8% (95% CI, 4.0-7.7%; P Aboriginal people and other older Australians, suggesting that different approaches are required to prevent and treat fall injuries.

    Measurements of the mixing rates and cross sections for collisional excitation transfer between the 5P 1/2 and 5P 3/2 states of rubidium (Rb) in the presence of 4 He buffer gas are presented. Selected pulses from a high repetition rate, mode-locked femtosecond laser are used to excite either Rb state with the fluorescence due to collisional excitation transfer observed by time-correlated single-photon counting. The time dependence of this fluorescence is fitted to the solution of rate equations which include the mixing rate, atomic lifetimes and any quenching processes. The variation in the mixing rate over a large range of buffer gas densities allows the determination of both the binary collisional transfer cross section and a three-body collisional transfer rate. We do not observe any collisional quenching effects at 4 He pressures up to 6 atm and discuss in detail other systematic effects considered in the experiment. (paper)

De entre todas las manifestaciones de la desigualdad, se centra en sus aspectos más subjetivos: la autopercepción y la representación de la estructura. El artículo se divide en tres partes; en la primera se plantean las cuestiones que afectan a la definición subjetiva de clase, distinguiendo entre el ser, el sentirse y el hacer, en la segunda se presentan, del modo más sistematico y abreviado posible, los resultados de casi cincuenta años (1950-1995 de investigación empírica en España sobre clases sociales. El objetivo de esta presentación crítica es mostrar las diferencias de enfoque y el efecto de la forma de aproximación de los investigadores sobre los resultados obtenidos. En la tercera parte se ofrecen los resultados inéditos, o escasamente divulgados todavía, de varias encuestas nacionales realizadas recientemente en el Csic y en Cires, en las que se ha concedido cierta relevancia al tema de la desigualdad social y sus manifestaciones actitudinales o autoperceptivas. A partir de estos resultados, y por comparación con los restantes, se analiza el imaginario colectivo español referido a la estructura social, lo que podría llamarse la nueva iconografía sociológica, y el papel jugado por los agentes sociales en la modelación de estas imágenes.

    Full Text Available The Master of Public Health (MPH is an internationally recognised post-graduate qualification for building the public health workforce. In Australia, MPH graduate attributes include six Indigenous public health (IPH competencies. The University of Melbourne MPH program includes five core subjects and ten specialisation streams, of which one is Indigenous health. Unless students complete this specialisation or electives in Indigenous health, it is possible for students to graduate without attaining the IPH competencies. To address this issue in a crowded and competitive curriculum an innovative approach to integrating the IPH competencies in core MPH subjects was developed. Five online modules that corresponded with the learning outcomes of the core public health subjects were developed, implemented and evaluated in 2015. This brief report outlines the conceptualisation, development, and description of the curriculum content; it also provides preliminary student evaluation and staff feedback on the integration project.

    1. A study has been made of the properties of a hitherto unreported proteolytic enzyme from the latex of the milkweed, Asclepias speciosa. The new protease has been named asclepain by the authors. 2. The results of chemical, diffusion, and denaturation tests indicate that asclepain is a protein. 3. Like papain, asclepain dots milk and digests most proteins, particularly if they are dissolved in concentrated urea solution. Unlike papain, asclepain did not clot blood. 4. The activation and inhibition phenomena of asclepain resemble those of papain, and seem best explained on the assumption that free sulfhydryl in the enzyme is necessary for proteolytic activity. The sulfhydryl of asclepain appears more labile than that of papain. 5. The measurement of pH-activity curves of asclepain on casein, ovalbumin, hemoglobin, edestin, and ovovitellin showed no definite digestion maxima for most of the undenatured proteins, while in urea solution there were well defined maxima near pH 7.0. Native hemoglobin and ovovitellin were especially undigestible, while native casein was rapidly attacked. 6. Temperature-activity curves were determined for asclepain on hemoglobin, casein, and milk solutions. The optimum temperature was shown to increase with decreasing time of digestion. PMID:19873154

    1. The kinetics of milk clotting by asclepain, the protease of Asclepias speciosa, were investigated. At higher concentrations of enzyme, the clotting time was inversely proportional to the enzyme concentration. 2. The digestion of casein and hemoglobin in 6.6 M urea by asclepain follows the second order reaction rate. The rate was roughly second order for casein in water. 3. Evaluation of the nature of the enzyme-substrate intermediate indicates that one molecule of asclepain combines with one molecule of casein or hemoglobin in urea solution. 4. Inhibition by the reaction products was deduced from the fact that the digestion velocity of hemoglobin in urea solution varied with the asclepain concentration in agreement with the Schütz-Borissov rule.

    National cancer survival statistics are available for the total Australian population but not Indigenous Australians, although their cancer mortality rates are known to be higher than those of other Australians. We aimed to validate analysis methods and report cancer survival rates for Indigenous Australians as the basis for regular national reporting. We used national cancer registrations data to calculate all-cancer and site-specific relative survival for Indigenous Australians (compared with non-Indigenous Australians) diagnosed in 2001-2005. Because of limited availability of Indigenous life tables, we validated and used cause-specific survival (rather than relative survival) for proportional hazards regression to analyze time trends and regional variation in all-cancer survival between 1991 and 2005. Survival was lower for Indigenous than non-Indigenous Australians for all cancers combined and for many cancer sites. The excess mortality of Indigenous people with cancer was restricted to the first three years after diagnosis, and greatest in the first year. Survival was lower for rural and remote than urban residents; this disparity was much greater for Indigenous people. Survival improved between 1991 and 2005 for non-Indigenous people (mortality decreased by 28%), but to a much lesser extent for Indigenous people (11%) and only for those in remote areas; cancer survival did not improve for urban Indigenous residents. Cancer survival is lower for Indigenous than other Australians, for all cancers combined and many individual cancer sites, although more accurate recording of Indigenous status by cancer registers is required before the extent of this disadvantage can be known with certainty. Cancer care for Indigenous Australians needs to be considerably improved; cancer diagnosis, treatment, and support services need to be redesigned specifically to be accessible and acceptable to Indigenous people.

    We have studied the broadening and shift of argon spectral lines corresponding to 3p 5 5p-3p 5 4s and 3p 5 4p-3p 5 4s transitions emitted from an electric arc burning under atmospheric pressure. We have revealed the broadening due to neutral atoms pressure effect, distinguishing the transitions whose lower level is a metastable one (1s 3 and 1s 5 ) or a level of strong (1s 2 ) or feeble resonance (1s 4 ). In this study we have employed a mixture of argon (98%) and hydrogen (2%); hydrogen's feeble proportion does not perturb much the discharge and is very suitable for the measure of the electronic density. The important departure of L.T.E. has guided us to imagine and apply an original method to measure the temperature and the overpopulation of the neutral atoms in the fondamental state. Our method which is independent of the existence of L.T.E. is based on the different behavior of the spectral lines which are under the influence of the resonance or Van der Waals broadening. The measure of the broadening constants which in the resonance case are independent of the temperature and vary as Tsup(0,3) for V.d.W's broadening, give us a suitable tool to measure the density and the temperature of the neutral atoms [fr

    V530 Ori was monitored spectroscopically with three different instruments over a period of more than 17 yr. Observations began at the Harvard-Smithsonian Center for Astrophysics (CfA) in 1996 June with a Cassegrain-mounted echelle spectrograph ("Digital Speedometer", DS; Latham 1992ASPC...32..110L) attached to the 1.5 m Tillinghast reflector at the F. L. Whipple Observatory (Mount Hopkins, AZ). We gathered a further 30 spectra of V530 Ori at the Kitt Peak National Observatory (KPNO) from 1999 March to 2001 January, using the coude-feed telescope and the coude spectrometer. Finally, 41 additional observations were obtained at the CfA from 2009 November to 2014 March with the Tillinghast Reflector Echelle Spectrograph (TRES; Furesz 2008, PhD thesis , Univ. Szeged, Hungary) on the 1.5 m telescope mentioned earlier. Two sets of V-band images of V530 Ori were obtained with independent robotic telescopes operating at the University of Arkansas (URSA WebScope) and near Silver City, NM (NFO WebScope) from 2001 January to 2012 February. Differential photometric measurements of V530 Ori were also gathered with the Stromgren Automatic Telescope at ESO (La Silla, Chile), during several campaigns from 2001 January to 2006 February.

    To determine whether participation in the continuous quality improvement (CQI) Audit and Best Practice for Chronic Disease programme improved care and outcomes for Indigenous children. Data were collected from 59 Australian primary health-care centres providing services to Indigenous people and participating in the programme (February 2008 and December 2013). Indigenous children aged less than 2 years and centres that completed three or more consecutive annual audits within the 6-year study period were included. Crude and adjusted logistic generalised estimating equation models were used to examine the effect of year of audit on the delivery of care. Odds ratio (OR) and 95% confidence interval (CI) were calculated. Outcomes were related to age-relevant health issues, including prevention and early intervention. These included administrative, health check, anticipatory guidance and specific health issues. During the audit period, there were 2360 files from 59 centres. Those that had a recall recorded, improved from 84 to 95% (OR 2.44, 95% CI 1.44-4.11). Hearing assessments improved from 52 to 89% (OR 1.37, 95% CI 1.22-1.54). Improvement in anticipatory guidance, treatment and follow-up of medical conditions was almost universal. We documented significant improvements in quality of care of Indigenous children. Outcomes and their corresponding treatment and follow-ups improved over time. This appears to be related to services participating in annual CQI activities. However, these services may be more committed to CQI than others and therefore possibly better performing. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    Indigenous primary health-care (PHC) services participating in continuous quality improvement (CQI) cycles show varying patterns of performance over time. Understanding this variation is essential to scaling up and sustaining quality improvement initiatives. The aim of this study is to examine trends in quality of care for services participating in the ABCD National Research Partnership and describe patterns of change over time and examine health service characteristics associated with positive and negative trends in quality of care. PHC services providing care for Indigenous people in urban, rural, and remote northern Australia that had completed at least three annual audits of service delivery for at least one aspect of care (n = 73). Longitudinal clinical audit data from use of four clinical audit tools (maternal health, child health, preventive health, Type 2 diabetes) between 2005 and 2013 were analyzed. Health center performance was classified into six patterns of change over time: consistent high improvement (positive), sustained high performance (positive), decline (negative), marked variability (negative), consistent low performance (negative), and no specific increase or decrease (neutral). Backwards stepwise multiple logistic regression analyses were used to examine the associations between health service characteristics and positive or negative trends in quality of care. Trends in quality of care varied widely between health services across the four audit tools. Regression analyses of health service characteristics revealed no consistent statistically significant associations of population size, remoteness, governance model, or accreditation status with positive or negative trends in quality of care. The variable trends in quality of care as reflected by CQI audit tools do not appear to be related to easily measurable health service characteristics. This points to the need for a deeper or more nuanced understanding of factors that moderate the effect of CQI on health service performance for the purpose of strengthening enablers and overcoming barriers to improvement.

    The present summary describes the carried out work of the application of the techniques of gamma profiling in a distillation tower, for the oil industry in Mexico. The study consisted on the application of the gamma profiling technique. An arrangement detector source aligned in a horizontal way was collocated to make a vertical scanning along the tower, in such a way that the signal obtained by this technique allows see the interior of the same one, with the objective of being able to diagnose its operation conditions. According to the applied technique, the height of the signal obtained in the graphs depends on the attenuation of the source radiation, in such a way that if crosses areas of more or small density, the width of the signal decreases or is increased and starting from these results a diagnostic was interpreted. For the profiling service of the distillation tower, Na-24 source and radiation detection equipment coupled to a system of data acquisition was used. Relative to radiological protection a controlled area was defined where the radioactive source was used to avoid unnecessary exhibitions to the plant personnel. Relative to the technique use, in this case stands out the use of Na-24 like source since they required this way the conditions of thickness and diameter of the tower. At the end of the study satisfactory results were obtained. (Author)

    Mentoring is a key predictor of empowerment and prospectively a game changer in the quest to improve health inequities. This systematic review reports on the state of evidence on mentoring for Indigenous Australians by identifying the quantity, nature, quality and characteristics of mentoring publications. Thirteen databases were searched using specific search strings from 1983 - 2012. Grey literature was also canvassed. The resultant publications were mined to identify their outputs, nature, and quality. These were then conceptually mined for their characteristics to develop a model of mentoring that included the initiating environments, facilitating environments, operational strategies and outcomes. 771 citations were identified; 37 full text publications met inclusion criteria and were assessed. Fifteen were eligible for review. Four of five original research publications used strong qualitative research designs. No publications were found before 1999; the largest proportion concentrated in 2011 (n = 4). Facilitating environments included: mapping participants' socio-cultural and economic context; formal mentoring practices with internal flexibility; voluntary participation; integrated models with wrap-around services; mentor/staff competencies; and sustained funding. Mentoring strategies comprised: holistic scaffolding approaches; respectful, trusting, one-on-one mentoring relationships; knowledgeable mentors; regular contact; longer-term relationships and exit strategies; culturally-tailored programs; personal and social development opportunities; and specialised skills and learning opportunities. Outcomes varied in accordance to program aims and included improvements in aspects of education and employment, offending behaviours, relationships, and personal, social and professional development. Little research explored the effectiveness of mentoring, captured its impact qualitatively or quantitatively, developed appropriate measures or assessed its cost-effectiveness. There is a real need to evaluate programs particularly in terms of outcomes and, given there were no economic evaluations, costs. Commitments to improving Indigenous Australian mentoring rely on changes to funding structures and attitudes toward research. There was insufficient evidence to confidently prescribe a best practice model. Sufficient frequency of qualitative reporting between publications concluded that mentoring is a valuable empowerment strategy in the areas of health and wellbeing, education and employment and as a remedial and preventative measure in reducing offending behaviours. An evidence-informed mentoring model would take into account the key findings of the review.

    Full Text Available In the regions of the so called "purple soils", in the State of São Paulo and Northern Paraná, coffee harvested from the ground is attended by a number of foreign matter among which lumps of soils of varying sizes make up the bulk of it. The separation of such lumps as attained by mechanical devices usually employed is always not satisfactory, the result being that remaining lumps will give a red color to the coffee beans, thus lowering the grade. Since the soil lumps have an appreciable amount of iron oxyde, mainly in the form of magnetite (Fe3O4 ; there would appear that the use of electro-magnets or permanent magnets of high power would give good results. A new machine "catador Dr. Isay" having rotative permanent magnets thus appeared in the market and tests were officiary run to determine its perfomance. It was verified that such machine performs a good job in the separation of small lumps, just the ones which are not efficiently separeted by other types of machines usually employed like "washers" (lavadores "assorting machines" (seletores, and "stoners" (catadores de pedra. A theoretical study of the new machine "catador Dr. Isay" was also perfomed, showing that the following factors are likely to have an important bearing on its performances : a centrifugal force to which the lumps are subjected which is dependent upon the velocity of the magnetic rolls and the lumps effective size ; b shape of the "entre-ferro" ; c characteristics of the material employed in the manufacture of the permanent magnet. In this respect it seems advisable to recommend the use of alnico alloys, mainly class 5 and 6.

    Full Text Available The study and development of plant resources in arid-saline environments is increasing. Salicornia bigelovii is a halophyte of great interest. However, the productivity of these plants is limited by nitrogen availability. An alternative to chemical fertilizers are the plant growth promoting bacteria and mycorrhizae. In the present study was evaluated the effect of Glomus intraradices, three strains of rhizobacteria (Klebsiella pneumoniae, Bacillus amyloliquefaciens and Azospirillum halopraeferens and two soil types (clayey and sandy on Salicornia under greenhouse conditions. The inoculation of bacteria under conditions of sandy soil significantly stimulated growth and nutritional factor of Salicornia (NPK. Synergism was observed between G. intraradices and rhizobacteria. When inoculated bacteria in individually form, behaved with significant differences. There was synergism between G. intraradices and Klebsiella pneumoniae and A. halopraeferens in the uptake of N, the opposite happened with G. intraradices and Bacillus amyloliquefaciens with high significant values in the absorption of P and K. The soil was a determining factor in behavior and expression of the benefit of the microorganisms. Rhizobacteria and mycorrhiza in the study have potential for use as growth promoters in salicornia.

    Full Text Available We use stone tool refitting to assess palimpsest formation and stratigraphic integrity in the basal units of the Gruta da Oliveira archeo-stratigraphic sequence, layers 15-27, which TL and U-series dating places in late Marine Isotope Stage (MIS 5 or early MIS 4. As in most karst contexts, the formation of this succession involved multiple and complex phenomena, including subsidence, bioturbation, carnivore activity and runoff as agents of potential post-depositional disturbance. During phases of stabilization, such as represented by layers 15, 21 and 22, the excavated area was inhabited and refits corroborate that post-depositional displacement is negligible. Layers 23-25 and 16-19 correspond to subdivisions that slice thick geological units primarily formed of material derived from the cave's entrance via slope dynamics. Refit links are consistent with rapid fill-up of the interstitial spaces found in the Karren-like bedrock (for layers 23-25, or left between large boulders after major roof-collapse events (for layers 16-19. Layers 26 (the "Mousterian Cone" and 27 are a "bottom-of-hourglass" deposit underlying the main sedimentary body; the refits show that this deposit consists of material derived from layers 15-25 that gravitated through fissures open in the sedimentary column above. Layer 20, at the interface between two major stratigraphic ensembles, requires additional analysis. Throughout, we found significant vertical dispersion along the contact between sedimentary fill and cave wall. Given these findings, a preliminary analysis of technological change across the studied sequence organized the lithic assemblages into five ensembles: layer 15; layers 16-19; layer 20; layers 21-22; layers 23-25. The lower ensembles show higher percentages of flint and of the Levallois method. Uniquely at the site, the two upper ensembles feature bifaces and cleavers.

    The mechanical behavior of a filled elastomer was studied with emphasis on understanding the vacuum-material interactions occurring, and to develop analytical techniques for predicting the vacuum behavior. The test results indicate that two separate mechanisms are involved in the observed property changes: the first controls the time response to applied stress; the second determines the initial internal state of the materials as the result of stresses. It is concluded that the mechanical property changes are attributable to changes in the relaxation processes occurring in the material. These changes are brought about by outgassing of water. Recommendations for future investigations are included.

    Full Text Available This paper presents the study of a complex architectonical area within the so-called provincial forum of Tarraco. The analysis of the architectonical stratigraphy and of the construction processes has been a fundamental tool to understand an area characterized by a complicated urban evolution, showing the development of the building project of such a vast construction as it is the provincial forum. Unfortunately, the absence of data provided by archaeological excavations limits the definition of a precise absolute chronology. The process of transforming the top of Tarraco’s hill into a monumental area started, according to historical and numismatic sources, during the Julio-Claudian era was completed in the Flavian one by ending this monumental complex distributed in three platforms. The area here analysed, placed close to the circus, belongs to a system of substructiones which commonly features those forum and sacred complexes organized in platforms at different levels.El artículo presenta el estudio de un área arquitectónicamente compleja, integrada dentro del denominado Foro Provincial de Tarraco. El análisis de la estratigrafía arquitectónica y de los procesos de construcción, ha representado un instrumento fundamental para la interpretación de un área caracterizada por una compleja evolución urbanística, poniendo en evidencia el desarrollo del proyecto constructivo de una obra de gran envergadura como la del Foro Provincial. Desafortunadamente, la ausencia de datos procedentes de las excavaciones arqueológicas, ha limitado la definición de una cronología absoluta exacta. El proceso de monumentalización de la cima de la colina tarraconense iniciado, según las fuentes históricas y numismáticas, en época julio-claudia, culminó en época Flavia con la finalización del complejo monumental distribuido en tres terrazas. El sector que se examina, situado junto al circo, se encuadra dentro de un sistema de substructiones que a menudo caracterizan los conjuntos forense y sacro organizados en terrazas.

    The timing, structure and termination of the last southern mountain glaciation and its forcing remains unclear. Most studies have focused on the global Last Glacial Maximum (LGM; 26.5-19 ka) time period, which is just part of the extensive time-frame within the last glacial period, including Marine Isotope Stages 3 and 4. Understanding the glacial fluctuations throughout the glacial period is a prerequisite for uncovering the cause and climate mechanism driving southern glaciation and the interhemispheric linkages of climate change. Here, we present an extensive (n = 65) cosmogenic 10Be glacier chronology derived from moraine belts marking the pre-global LGM extent of the former Patagonian Ice Sheet in southernmost South America. Our results show the mountain ice sheet reached its maximum extent at 48.0 ± 1.8 ka during the local LGM, but attained just half this extent at 21.5 ± 1.8 ka during the global LGM. This finding, supported by nearby glacier chronologies, indicates that at orbital time scales, the southern mid-latitude glaciers fluctuated out-of-phase with northern hemisphere ice sheets. At millennial time-scales, our data suggest that Patagonian and New Zealand glaciers advanced in unison with cold Antarctic stadials and reductions in Southern Ocean sea surface temperatures. This implies a southern middle latitudes-wide millennial rhythm of climate change throughout the last glacial period linked to the north Atlantic by the bipolar seesaw. We suggest that winter insolation, acting alongside other drivers such as the strength and/or position of the southern westerlies, controlled the extents of major southern mountain glaciers such as those in southernmost South America.

    Full Text Available This study estimates fatal and nonfatal disease burden among Indigenous Australians in 2011 and compares it with non-Indigenous Australians. The study found that there were 284 years lost per 1000 people because of premature death or living with ill health. Most of the disease burden was from chronic diseases (64%, particularly mental and substance-use disorders, injuries, cardiovascular diseases, cancer and respiratory diseases. The burden of disease was higher among males (54% than females (46% and higher for fatal (53% than for nonfatal burden (47%. The disease groups with the highest burden varied by age group, with mental and substance-use disorders and injuries being the largest disease groups among those aged 5–44 years, and cardiovascular disease and cancer becoming more prominent among those aged 45 and older. Large disparities existed between Indigenous and non-Indigenous Australians, with the total burden being 2.3 times the non-Indigenous rates, fatal burden being 2.7 times and nonfatal burden being 2 times.

    Electronic mental health (e-mental health) interventions offer effective, easily accessible, and cost effective treatment and support for mental illness and well-being concerns. However, e-mental health approaches have not been well utilized by health services to date and little is known about their implementation in practice, particularly in diverse contexts and communities. This study aims to understand stakeholder perspectives on the requirements for implementing e-mental health approaches in regional and remote health services for Indigenous Australians. Qualitative interviews were conducted with 32 managers, directors, chief executive officers (CEOs), and senior practitioners of mental health, well-being, alcohol and other drug and chronic disease services. The implementation of e-mental health approaches in this context is likely to be influenced by characteristics related to the adopter (practitioner skill and knowledge, client characteristics, communication barriers), the innovation (engaging and supportive approach, culturally appropriate design, evidence base, data capture, professional development opportunities), and organizational systems (innovation-systems fit, implementation planning, investment). There is potential for e-mental health approaches to address mental illness and poor social and emotional well-being amongst Indigenous people and to advance their quality of care. Health service stakeholders reported that e-mental health interventions are likely to be most effective when used to support or extend existing health services, including elements of client-driven and practitioner-supported use. Potential solutions to obstacles for integration of e-mental health approaches into practice were proposed including practitioner training, appropriate tool design using a consultative approach, internal organizational directives and support structures, adaptations to existing systems and policies, implementation planning and organizational and government investment.

  13. Optimization of lime addition in a dry air pollution control device; Optimerad rening av HCl och SO{sub 2} med minskade kalktillsatser vid torr roeasrening

    The focus of this project is to optimize the absorption of hydrochloric acid (HCl) and sulphuric acid (SO{sub 2}) in a dry air pollution control device system connected to a waste combustor. A significant amount of absorbent are generally added into the processes to achieve an efficient cleaning of the flue gas. Reduced absorbent consumption has double benefits on the operative expenses due to decreased purchase and landfilling costs. The objective was to study the affect of flue gas temperature and moisture, (relative humidity, RH), on the efficiency of HCl and SO{sub 2} absorption on hydrated lime. Additionally, the efficiency of a pre-treated hydrated lime with larger specific surface and pore volume was investigated. The measuring campaign was conducted on the 20 MW fluidized bed waste incinerator own by Boraas Energi och Miljoe AB in Sweden. Results from 26 experimental days with normal hydrated lime showed a positive correlation between the efficiency of the lime and RH in the flue gas. Four levels of RH between 3.28% to 4.84% were tested. The levels were adjusted by lowering the flue gas temperature and/or by adding water to the waste fuel. The smallest effect where achieved by solely adding water to the waste fuel. RH increased solely to 3.62% and the amount of lime consumption was reduced with only 5% compare to normal condition. By lowering the flue gas temperature 10 deg C to 143 deg C, RH increased to 4.06% and the amount of lime added was reduced with 13%. The largest impact was found when both the flue gas temperature and the moisture content were changed. At those process conditions RH reach 4.84 % and the usage of lime were reduced with 26%. Additional 12 experimental days were conducted to evaluate the efficiency of a pretreated hydrated lime with larger specific surface and pore volume. The results showed that the surface enlarged absorbent was almost twice as effective as the normal hydrated lime. Moreover, the results indicated an equal dependency of variation in RH (valid within temperature window between 145-165 deg C) for the surface enlarged absorbent as for the one identified for normal hydrate lime. Results that showed additional potential to reduce in the amount of surfaced enlarged absorbent needed by optimizing the processes further. The annual operative expenses of the studied waste combustor can be reduced by 700,000 SEK (100,000 USD) by increasing the RH to 4.5% and thus reduce the amount of added normal hydrate lime with 20%. Furthermore, the annual cost can be reduced with additionally 700,000 SEK by using an absorbent with higher specific surface and pore volume. Evaluation of an on-line FTIR-system measuring the levels of HCl and SO{sub 2} in the raw gas of the waste incinerator showed the 80% of the HCl was detected in the gas-phase and 20% were capture on the particles. Reverse results were obtained for SO{sub 2}. However, the levels of SO{sub 2} in the flue gas were rather low, which may have affected the results.

    Full Text Available En este artículo se presenta un software desarrollado para la enseñanza del proceso de destilación por etapas, enfocado para ser utilizado por los estudiantes de pregrado de Ingeniería Química. Se expone en él un marco general de los procesos de separación, haciendo énfasis en el proceso de la destilación, sus orígenes, su importancia y sus perspectivas. Posteriormente se desarrolla el tema del equilibrio de fases, que,junto con el concepto de etapa de equilibrio, fundamentan el cálculo de la destilación por etapas. En este último aspecto se realiza una explicación de los modelos matemáticos más representativos para las mezclas binarias, de una manera relativamente completa, mientras que se establece una aproximación al estudio de algunos modelos para mezclas multicomponentes. Para esto se implementan programas tutores, que presentan paso a paso el procedimiento para resolver un problema planteado por el usuario, a la vez que se obtienen los resultados. Además, con una intención centrada en solucionar un problema sin revisar el procedimiento de cálculo, se adicionan programas simuladores para los diferentes modelos estudiados.

    Issue addressed Aboriginal youth in Australia often experience high rates of intimate partner violence (family violence) and poorer reproductive and sexual health than their non-Aboriginal counterparts. To address some of the disparities, the Strong Family Program was developed to deliver reproductive and sexual health education to Aboriginal communities in New South Wales. Methods Development of the program was based on an extensive consultation process with Aboriginal communities. It was implemented in three communities, with two groups from each hosting Aboriginal youth and Elders in a yarning circle within the culturally respectful frameworks of 'men and boys'' and 'women and girls'' business. An evaluation was conducted to measure reproductive and sexual health knowledge and attitude changes upon program completion, using pre- and post-program surveys and yarning (focus group discussions). Results Program participants comprised 48 females and 28 males. Overall, mean knowledge and attitude scores improved upon completion of the program (from 77% to 82% and from 4.15 to 4.32 out of 5, respectively). Among participants aged 20 years and under (the youngest participant was 13 years), there was an increase in knowledge (P=0.034); among participants aged over 20 years (the oldest participant was 78 years), there was an increase in positive attitudes (P=0.001). Participants perceived the information provided to be useful and relevant, with many reporting improved knowledge and attitudes around rights and respectful relationships. Conclusions Reproductive and sexual health education in Aboriginal communities should be based on community consultations and carried out within a culturally appropriate framework to promote greater success. Continued implementation of the Strong Family Program will promote increased understanding of respectful relationships and improved health outcomes for Aboriginal young people. So what? The Strong Family Program was based on an extensive consultative process that ensured leadership and involvement from Aboriginal communities, with program content and delivery based on Aboriginal pedagogy and reflecting Aboriginal cultural values. Reproductive and sexual health promotion in Aboriginal communities should be based on community consultations and carried out within a culturally appropriate framework to promote greatest success.

    Nitrogen is the nutrient that generally limits the amount of manure that can be applied to the land in accordance with current regulatory requirements. This is the reason why nitrogen removal has tended to be a major focus in the development of agricultural wastes treatment procedures. In this study, a denitrogenation pilot-plant was designed and constructed in order to investigate air stripping as method for removing ammonia from liquid fraction of swine manure wastewaters. The high ammonia removal efficiency reached using the air stripping method indicates that it could provide an interim solution for current waste management problems in the swine industry. The developed technology is applicable to middle-size pig farms, thanks to the reduce cost of the necessary facilities and to the managing and maintenance facility of the equipment. (Author) 5 refs.

    In this work, the behavior of the AISI 444 ferritic stainless steel submitted to thermal fatigue test and their corrosion resistance in heavy crude oil was evaluated. The AWS E309MoL-16 and E316L-17 weld metal was employed as filler metal. Plates of the AISI 444 were welded on ASTM A-516 Gr. 60 plates and submitted to fatigue thermal cycle. Samples were extracted from plates welded and heat treated immersed in heavy crude oil at 300 deg C. Optical microscopy (OM), scanning electron microscopy (SEM) and energy dispersive of X-ray analysis (EDX) were used to characterize the microstructure and the corroded surface. The results show that the AISI 444 stainless steels did not present cracks after the thermal fatigue cycle and the heat treated immerse in heavy crude oil. The electrode AWS E309MoL-16 show better corrosion resistance than the AWS E316L-17. (author)

    Full Text Available Abstract Background Sexually transmitted infections (STIs have been increasing among Australian Indigenous young people for over two decades. Little is known about the association between alcohol and other drug use and sexual risk behaviours and diagnosis of STIs among this population. Methods A cross-sectional, community based self-administered survey was conducted among young Aboriginal people aged 16–29 years of age. Questionnaires included socio-demographic characteristics, knowledge, sexual risk behaviours alcohol and other drug use and health service access including self-reported history of diagnosis with a STI. Logistic regression models and population attributable risks were used to assess individual and population level impacts of illicit drug use on high risk sexual behaviours and ever reported diagnosis of an STI. Results Of the 2877 participants, 2320 (81 % identified as sexually active and were included in this study. More than 50 % of the study population reported that they had used at least one illicit drug in past year. Cannabis, ecstasy and methamphetamines were the three most commonly used illicit drugs in the past year. The prevalence of self-reported STI diagnosis was 25 %. Compared with people who did not report using illicit drugs, risky alcohol use and sexual behaviours including inconsistent condom use, multiple sexual partners in the past year and sex with casual partners were all significantly higher among illicit drug users. In adjusted analysis, participants who reported using illicit drugs were significantly more likely to engage in sexual risk behaviours and to ever have been diagnosed with an STI. Adjusted Odds Ratios ranged from 1.86 to 3.00 (males and from 1.43 to 2.46 (females. At the population level, more than 70 % of the STI diagnoses were attributed to illicit drug-use and sexual risk behaviours for males and females. Conclusion Illicit drug use in this population is relatively high compared to other similar aged populations in Australia. Illicit drug use was associated with risky sexual behaviours and STI diagnoses among this study population. Developing and implementing effective STI prevention strategies should include not only safe sex messages but also include drug and alcohol harm reduction messages.

    This paper analyzes the concept of a decentralized power system based on wind energy and a pumped hydro storage system in a tall building. The system reacts to the current paradigm of power outage in Latin American countries caused by infrastructure limitations and climate change, while it fosters the penetration of renewable energy sources (RES) for a more diversified and secure electricity supply. An explicit methodology describes the assessment of technical, operational and economic potentials in a specific urban setting in Caracas/Venezuela. The suitability, applicability and the impacts generated by such power system are furthermore discussed at economic, social and technical level. - Highlights: ► We have modeled an innovative pico pumped hydro-storage system and wind power system for tall buildings. ► We conducted technical, economic and social analysis on these energy supply and storage alternatives. ► The energy storage system can achieve efficiencies within 30% and 35%. ► The energy storage is realistic and economic sensible in comparison to other solutions. ► The impacts of such a system in the current living conditions and safety issues of the building are minimum

    The analysis of a natural draught tower in open circuit for the cooling system of seawater circulation on the nuclear power plant of Laguna Verde, it is based on conditions of 2027 MWt and 2317 MWt, where the flows of circulation water system hardly vary and whose purpose will be, to cool the seawater circulation. The circulation water system is used as heat drain in main condenser of turbo generator to condense the nuclear vapor. The annual average temperature in the seawater at present is of 26 C to the entrance to circulation water system and it is vary in accordance with the time of year. The mean temperature of leaving of circulation water system to the sea is of 41 C. Having a cooling tower to reduce the entrance temperature to the circulation water system, it improves the efficiency of thermal transfer in condenser, it improves the vacuum in condenser giving more operative margin to avoid condenser losses by air entrances and nuclear power plant shutdowns, as well as for to improve the efficiency of operative balance of nuclear power plant, also it prevents the impact in thermal transfer efficiency in condenser by the climatic change.

    Wastewater regeneration and reuse of regenerated water permits to increase the amount of water and guarantees the availability required, in terms of both quantity and quality. In this context, a research project on regenerated water reuse for cooling towers has been carried out by the Universitat Politecnica de Catalunya (UPC), the Water Catalan Agency (ACA) and the Council of Chambers of Commerce. The research consisted of two steps. A first objective was to verify the effect of water source in the colonization of cooling towers by Legionella. In order to achieve those objectives, effluents from different wastewater treatment plant stages were used. The second objective was to evaluate in situ the disinfection process in order to decrease the sanitary risk from water reuse for cooling towers. For the entire duration of the project, both conventional culture methods and new molecular techniques with real times PCR were performed to detect Legionella from water samples. (Author) 17 refs.

    The aim of this paper is to simulate a solar thermal electricity pilot plant at the Campus of the Federal University of Rio de Janeiro (UFRJ), at Fundao Island, which would generate part of the electricity demanded by the Technology Center (CT) of the UFRJ. Based on the electricity demand from UFRJ and the electric prices paid by the institution, this study proposes the construction of a 1MW Concentrated Solar Power (CSP) pilot plant and analyses the economical, energy and environmental viability of implementation of this plant, operating from 2015 to 2045. This CSP plant would cover a field of 0,01km{sup 2} and have a 30% of capacity factor. This study also evaluates the impact caused by the substitution of the current Campus internal bus fleet for plug-in hybrid electric buses. The current service is provided by Normandy, which operates 12 buses plus 1 backup. These new buses would be regularly partially recharged by the energy generated from CSP. All the simulations have been made with the RETScreen software, which simulated the operation of the CSP, the amount of electricity produced, the carbon emissions avoided, the acquisition and implementation of the plug-in hybrid electric bus fleet and the cash flow. Six scenarios generated were, namely A1, B1, C1 (all for lower costs for the CSP plants) and A2, B2, C2 (for higher costs). For a social discount rate around 8% and along 30 years, only the A1, C1 and C2 scenarios showed a non-negative cash flow. Also, the emissions avoided were around 222 tCO{sub 2}/yr (or 6.660 tCO{sub 2} over 30 years) in the A1 and A2 scenarios, and around 550 tCO{sub 2}/yr (or 16.512 tCO{sub 2} over 30 years) in all others scenarios.

    Full Text Available Fusarium is one of the important genera associated with grasses as saprophytes, endophytes and pathogens. A study was carried out on distribution and diversity of Fusarium species associated with two groups of grasses in 10 states throughout Peninsular Malaysia i.e. agricultural grasses (Oryza sativa and Saccharum officinarum and non-agricultural grasses (Axonopus compressus, Centhotheca lappacea, Chloris barbata, Crysopogon aciculatus, Cyanadon dactylon, Dactyloctenium aegyptium, Digitaria ciliaris, Echinochloa colona, Eleusine indica, Eragrostis amabilis, Eragrostis malayana, Eragrostis uniloides, Ischaemum magnum, Panicum brevifolium, Panicum millaneum, Panicum repens, Paspalum commersonii, Paspalum conjugatum, Paspalum orbiculare, Pennisetum purpureum, Sacciolepis indica, Sporobolus diander and Sporobolus indicus. A total of 474 isolates were single-spored and identified by morphological characteristics. F. semitectum was frequently isolated (23.6%, followed by F. sacchari and F. fujikuroi with 15.4% and 14.6%, respectively. The other nine species were F. solani (10.3%, F. proliferatum (8.9%, F. oxysporum (7.4%, F. subglutinans (6.5%, F. equiseti (5.5%, F. verticillioides (3.4%, F. compactum (2.5%, F. chlamydosporum (1.1% and F. longipes (0.8%. Based on the Shannon-Weiner Index, F. solani was the highest (H' = 2.62 isolated from grasses. Species of Fusarium from O. sativa were widely diverse with 11 species, followed by non-agricultural grasses with nine species and S. officinarum with only six species. This is the first report on diversity of Fusarium associated with grasses in Malaysia.

  11. Tritium-caused background currents in electron multipliers

    1979-05-01

    One channel electron multiplier (Galileo No. 4501) and one 14 stage Be/Cu multiplier (Dumont No. SPM3) were exposed to tritium pressures between approx. 10 -7 Torr to 10 -3 Torr in amounts from approx. 10 -5 Torr-s to 60 Torr-s and the β-decay caused currents in the multipliers measured. The background currents in both multipliers consisted of two components: (1) a high, reversible current which was proportional to the tritium exposure pressure; and (2) a lower, irreversible background current which increased with increasing cumulative tritium exposure. The β-decay caused currents in each multiplier increased the same way with exposure, suggesting the detected electrons arose from decaying tritium adsorbed on surfaced external to the multipliers

    Full Text Available Coastal salt marshes are dynamic, intertidal ecosystems that are increasingly being recognised for their contributions to ecosystem services, including carbon (C accumulation and storage. The survival of salt marshes and their capacity to store C under rising sea levels, however, is partially reliant upon sedimentation rates and influenced by a combination of physical and biological factors. In this study, we use several complementary methods to assess short-term (days deposition and medium-term (months accretion dynamics within a single marsh that contains three salt marsh vegetation types common throughout southeastern (SE Australia.We found that surface accretion varies among vegetation assemblages, with medium-term (19 months bulk accretion rates in the upper marsh rush (Juncus assemblage (1.74 ± 0.13 mm yr−1 consistently in excess of estimated local sea-level rise (1.15 mm yr−1. Accretion rates were lower and less consistent in both the succulent (Sarcocornia, 0.78 ± 0.18 mm yr−1 and grass (Sporobolus, 0.88 ± 0.22 mm yr−1 assemblages located lower in the tidal frame. Short-term (6 days experiments showed deposition within Juncus plots to be dominated by autochthonous organic inputs with C deposition rates ranging from 1.14 ± 0.41 mg C cm−2 d−1 (neap tidal period to 2.37 ± 0.44 mg C cm−2 d−1 (spring tidal period, while minerogenic inputs and lower C deposition dominated Sarcocornia (0.10 ± 0.02 to 0.62 ± 0.08 mg C cm−2 d−1 and Sporobolus (0.17 ± 0.04 to 0.40 ± 0.07 mg C cm−2 d−1 assemblages.Elemental (C : N, isotopic (δ13C, mid-infrared (MIR and 13C nuclear magnetic resonance (NMR analyses revealed little difference in either the source or character of materials being deposited among neap versus spring tidal periods. Instead, these analyses point to substantial redistribution of materials within the Sarcocornia and

    Full Text Available Four dominant grass species (Hyparrhenia rufa, Melinis minutiflora, Pennisetum purpureum and Sporobolus africanus of natural pastures of the West Region of Cameroon were sampled at 60 sites between September and November of 1985. The grass samples were analysed for calcium, phosphorus, potassium, magnesium, sodium, iron, mangenese, copper and zinc. Serum was also collected from goats and sheep at the same locations where forages were sampled and analysed for calcium, phosphorus, magnesium, zinc and copper. Results showed that P, Mg, A/a, Zn and Cu in forages were generally below the critical level stipulated to satisfy the requirements of grazing livestock in the tropics. Calcium was inadequate in the sera of goats and sheep where as P, Mg, Zn and Cu were adequate. Use of salt licks to supplement intake of mineral elements from grasses by goats and sheep is necessary in the region.

  18. Riparian Vegetation Mapping Along the Hanford Reach

    International Nuclear Information System (INIS)

    FOGWELL, T.W.

    2003-01-01

    During the biological survey and inventory of the Hanford Site conducted in the mid-1990s (1995 and 1996), preliminary surveys of the riparian vegetation were conducted along the Hanford Reach. These preliminary data were reported to The Nature Conservancy (TNC), but were not included in any TNC reports to DOE or stakeholders. During the latter part of FY2001, PNNL contracted with SEE Botanical, the parties that performed the original surveys in the mid 1990s, to complete the data summaries and mapping associated with the earlier survey data. Those data sets were delivered to PNNL and the riparian mapping by vegetation type for the Hanford Reach is being digitized during the first quarter of FY2002. These mapping efforts provide the information necessary to create subsequent spatial data layers to describe the riparian zone according to plant functional types (trees, shrubs, grasses, sedges, forbs). Quantification of the riparian zone by vegetation types is important to a number of DOE'S priority issues including modeling contaminant transport and uptake in the near-riverine environment and the determination of ecological risk. This work included the identification of vegetative zones along the Reach by changes in dominant plant species covering the shoreline from just to the north of the 300 Area to China Bar near Vernita. Dominant and indicator species included Agropyron dasytachyudA. smithii, Apocynum cannabinum, Aristida longiseta, Artemisia campestris ssp. borealis var scouleriana, Artemisa dracunculus, Artemisia lindleyana, Artemisia tridentata, Bromus tectorum, Chrysothamnus nauseosus, Coreopsis atkinsoniana.

    The effect of oxygen pressure during pulsed laser deposition of Pb(Zr0.52Ti0.48)O3 (PZT) thin films on CoFe2O4 nano-seed layered Pt(111)/Si substrate was investigated. The PZT film deposited at oxygen pressure lower than 25 mTorr is identified as both perovskite and pyrochlore phases and the films deposited at high oxygen pressure (50-100 mTorr) show the single-phase perovskite PZT that has a perfect (111)-orientation. In addition, the film deposited at PO2 of 50 mTorr has a uniform surface morphology, whereas the film deposited at PO2 of 100 mTorr has a non-uniform surface morphology and more incompacted columnar cross-section microstructure. The polarization of film deposited at 100 mTorr is higher than that deposited at 50 mTorr, but shift of the hysteresis loop along the electrical field axis in the film deposited at PO2 of 100 mTorr is larger than that of the film deposited at PO2 of 50 mTorr.

    The rates for collisional broadening and shifting of the Rb D1 (52S1/2 - 52P1/2) and D2 (52S1/2 - 52P3/2) transition induced by 4He have been measured at elevated temperatures of 373-723 K. The shift coefficients exhibit an increase of 20% from 4.36 MHz/Torr to 5.35 MHz/Torr for the D1 line and an 80% increase from 0.42 MHz/Torr to 0.99 MHz/Torr for the D2 line over the observed temperature range. Broadening coefficients exhibit a 6% increase from 17.8 MHz/Torr to 18.9 MHz/Torr and 10% from 18.5 MHz/Torr to 20.5 MHz/Torr for the D1 and D2 lines, respectively. The experimental values agree well with prior reported values within the temperature overlap regions of T < 394 K. Comparison to prior predictions from the Anderson-Talman theory using spin orbit multi reference (SOCI) ab initio potentials are superior to quantum treatments involving Allard and Baranger coupling.

    The results of fabrication and performance of an ionization vacuum gauge using a carbon nanotube (CNT) electron source are presented. The electron source was constructed with multi-wall nanotubes (MWNT), which were grown using thermal chemical vapor deposition (CVD) process. The electron emission of the source was stable in vacuum pressure up to 10-7 Torr, which is better than the metal field emitters. The measurement linearity of the gauge was better than {+-}10% from 10-6 to 10-10 Torr. The gauge sensitivity of 4 Torr-1 was achieved under 50 {micro}A electron emission in nitrogen. The gauge is expected to find applications in vacuum measurements from 10-7 Torr to below 10-11 Torr.

    We used multiple regression analyses to determine the relationships between the decrement in sea level (SL, 760 Torr) VO2max during hypobaric hypoxia (HH) and variables that could alter or be related to the decrement in VO2max. HH conditions consisted of 682 Torr, 632 Torr, and 566 Torr, and the measured independent variables were SL-VO2max, SL lactate threshold (SL-LT), the change in hemoglobin saturation at VO2max between 760 and 566 Torr (delta SaO2max), lean body mass (LBM), and gender. Male (N = 14) and female (N = 14) subjects of varied fitness, training status, and residential altitude (1,640-2,460 m) completed cycle ergometry tests of VO2max at each HH condition under randomized and single-blinded conditions. VO2max decreased significantly from 760 Torr after 682 Torr (approximately 915 m) (3.5 +/- 0.9 to 3.4 +/- 0.8 L.min-1, P = 0.0003). Across all HH conditions, the slope of the relative decrement in VO2max (%VO2max) during HH was -9.2%/100 mm Hg (-8.1%/1000 m) with an initial decrease from 100% estimated to occur below 705 Torr (610 m). Step-wise multiple regression revealed that SL-VO2max, SL-LT, delta SaO2max, LBM, and gender each significantly combined to account for 89.03% of the variance in the decrement in VO2max (760-566 Torr) (P decrement in VO2max during HH. The unique variance explanation afforded by SL-LT, LBM, and gender suggests that issues pertaining to oxygen diffusion within skeletal muscle may add to the explanation of between subjects variability in the decrement in VO2max during HH.

    Modulated heat transfer in air subject to pressures from 760 Torr to 10-4 Torr is experimentally studied by means of a thermal-wave resonant cavity placed in a vacuum chamber. This is done through the analysis of the amplitude and phase delay of the photothermal signal as a function of the cavity length and pressure through of the Knudsen's number. The viscous, transitional, and free molecular regimes of heat transport are observed for pressures P>1.5 Torr, 25 mTorrheat transport.

The obtained average value was about 5x10 -8 torr with turbo-molecular and sputter ion pumps, and 1.1x10 -9 torr after baking. (author)

    We have studied the spin relaxation of 129 Xe nuclei due to collisions with Rb atoms at Xe pressures of 245--1817 Torr. Our results can be characterized by two parameters, the Rb- 129 Xe velocity-averaged binary spin-exchange cross section left-angle σv right-angle and a rate γ M that characterizes spin relaxation due to van der Waals molecules. Our results complement earlier studies performed at Xe pressures of about 1 Torr and N 2 pressures of 10--100 Torr. This work is useful for predicting spin-exchange rates between polarized Rb atoms and 129 Xe nuclei

    Herein, we report the growth, structural, morphological and electronic properties of Europium sesquioxide (Eu2O3) thin films on Si [1 0 0] substrate using pulsed laser deposition technique. The films were deposited at ˜750 °C substrate temperature while the oxygen partial pressure (OPP) was varied (vacuum,˜1 mTorr, ˜10 mTorr and ˜300 mTorr). X-ray diffraction results confirm the single phase cubic structure of the film grown at ˜300 mTorr. The XRD results are also supported by the Raman's spectroscopy results. Eu-3d XPS core level spectra confirms the dominant contributions from the "3+" states of Eu in the film.

    We have created an ionization type Vacuum gauge with sensor element based on an array of vertically aligned carbon nanotubes. Obtained asymmetrical current-voltage characteristics at different voltage polarity on the electrode with the CNTs. It was found that when applying a negative potential on an electrode with the CNTs, the current in the gap is higher than at a positive potential. In the pressure range of 1 ÷ 103 Torr vacuum gauge sensitivity was 6 mV/Torr (at a current of 4.5·10-5 A) and in the range of 10-5 ÷ 1 Torr was 10 mV/Torr (at a current of 1.3·10-5 A). It is shown that the energy efficiency of vacuum gauge can be increased in the case where electrode with CNT operates as an emitter of electrons.

    1974-01-01

    The effects were studied of low-pressure air on contamination and corrosion in the tantalum alloy T-111/lithium system at 980 and 1260 C. Capsules of T-111 containing lithium were exposed to six vacuum levels between 1 x 10 to the 8th power and 0.0003 torr by controlled air leakage into a vacuum system. Capsules exposed at 980 C and 0.0002 torr failed from intragranular oxidation. The remainder of the capsules completed the 96-hour tests. The depth of oxygen contamination was greater at 980 C than at 1260 C. Tests made at 0.0001 and 0.00001 torr levels caused large increases in the oxygen content of the T-111. Tests at 0.000001 torr or less produced no significant contamination. No lithium corrosion of the T-111 was observed under any of the conditions.

    2018-03-01

    Full Text Available The test of relational reasoning (TORR is designed to assess the ability to identify complex patterns within visuospatial stimuli. The TORR is designed for use in school and university settings, and therefore, its measurement invariance across diverse groups is critical. In this investigation, a large sample, representative of a major university on key demographic variables, was collected, and the resulting data were analyzed using a multi-group, multidimensional item-response theory model-comparison procedure. No significant differential item functioning was found on any of the TORR items across any of the demographic groups of interest. This finding is interpreted as evidence of the cultural fairness of the TORR, and potential test-development choices that may have contributed to that cultural fairness are discussed.

    Quantitative analysis by infrared technique was made on hydrogen fluoride (HF) contained in uranium hexafluoride (UF 6 ). It was found that, among the vibration-rotation bands, the R(1)-, R(2)-, P(2)- and P(3)-branches having relatively large absorbances are convenient for the analysis of HF. Upon comparing the calibration curves of pure HF with the HF absorbances observed in the presence of UF 6 (approx. 70--100 Torr), N 2 (approx. 100 Torr) and Ar(approx. 100 Torr) gases, it was observed that the first-mentioned calibration curve could be applied to the analysis of HF when mixed with other substances, as in the latter cases. The detectable limits of HF pressure, using a infrared cell of 10cm path length, were 0.5--1 Torr at room temperature. (auth.)

    Tube component is the one of the local component that is designed and constructed using local materials in the Center of Advanced Technology Research and Development, and used mainly for vacuum chamber of EBM vacuum system. Gas load, product gases from out gassing process, permeation, evaporation and leakage, are factors that can affect the vacuum level of the vacuum chamber. By baking out the vacuum chamber, the releasing process from inside and wall surface will be faster, so that the out gassing and permeation rate will increase. By applying baked out process the tube having better vacuum performance were obtained. From the calculation results for the vacuum level chamber having volume of 9,859 liter and surface area of 4004,45 cm 2 , without baking out the out gassing rate (Q D ) was 4,644 x 10 -6 Torr liter/sec., permeation (Q P ) was 4,923 x 10 -6 Torr liter/sec., leakage (Q L ) was 1,691 x 10 -9 Torr liter/sec, gas load (Q G ) was 9,568 x 10 -6 Torr liter/sec. By baking out at 104,3 o C we obtained (Q D ) 2,276 x 10 -5 Torr liter/sec, (Q P ) 1,831 x 10 -5 Torr liter/sec, (Q L ) 3,161 x 10 -9 Torr liter/sec, and (Q G ) 4,108 x 10 -5 Torr liter/sec. The experimental results indicated that the final vacuum level which can be obtained the tube component without baking out was 3.375 x 10 -6 Torr in 5.33 hours, and with baking out at 104,3 o C the vacuum level was 2,25 x 10 -6 Torr in 4,25 hours. Whereas the experimental results of vacuum components in EBM system to be obtained the vacuum were 3,1 x 10 -6 mbar (2,33.10 -6 Torr). Those result indicated that the tube components fulfill the requirement to be used for the vacuum chamber component in the vacuum system of EBM. (author)

    2003-01-01

    Vacuum analysis of scanning horn of electron beam machine (EBM) has been carried out. In EBM, electron beam produced by the electron gun is accelerated by the accelerating tube toward the target via scanning horn and window. To avoid the disturbance of electron beam trajectory in side the EBM, it is necessary to evacuate the EBM. In designing and constructing the scanning horn, vacuum analysis must be carried out to find the ultimate vacuum grade based on the analysis as well as on the test resulted by the vacuum pump. The ultimate vacuum grade is important and affecting the electron trajectory from electron gun to the target. The yield of the vacuum analysis show that the load gas to be evacuated were the outgassing, permeation and leakages where each value were 5.96487x10 -6 Torr liter/sec, 6.32083x10 -7 Torr liter/sec, and 1.3116234x10 -4 Torr liter/sec respectively, so that the total gas load was 1.377587x10 -4 Torr liter/sec. The total conductivity according to test result was 15.769 liter/sec, while the effective pumping rate and maximum vacuum obtained by RD 150 pump were 14.269 Torr liter/sec and 9.65x10 -6 Torr respectively, The vacuum steady state indicated by the test result was 3.5x10 -5 Torr. The pressure of 3.5x10 -5 Torr showed by the test is close to the capability of vacuum pump that is 2x10 -5 Torr. The vacuum test indicated a good result and that there was no leakage along the welding joint. In the latter of installation it considered to be has a pressure of 5x10 -6 Torr, because the aluminum gasket will be used to seal the window flanges and will be evacuated by turbomolecular pump with pumping rate of 500 liter/sec and ultimate vacuum of -10 Torr.

    It has been demonstrated that pulsed and continuous wave, rf-driven hydrogen discharges can be started with photoemission. The extracted H - current from a photoemission-started plasma has been investigated and does not differ significantly from that of a filament-started plasma. The minimum pressure for photoemissive starting was found to be higher than that of filament starting, 17 mTorr compared to 7 mTorr, respectively, in this particular configuration. copyright 1996 American Institute of Physics

    Conditions for the stable propagation of a pinched electron beam in low pressure gas (p approximately 0.1 to 100 torr) are described. The observed window of good propagation around p approximately 2 torr air is interpreted as the quenching of the two-stream mode by sufficiently high plasma density and collision frequency, and the simultaneous suppression of the resistive hose mode by sufficiently rapid generation of electrical conductivity from breakdown ionization

    Prolonged muscle exposure to low PO2 conditions may cause oxidative stress resulting in severe muscular injuries. We hypothesize that PO2 cycling preconditioning, which involves brief cycles of diaphragmatic muscle exposure to a low oxygen level (40 Torr) followed by a high oxygen level (550 Torr), can reduce intracellular reactive oxygen species (ROS) as well as attenuate muscle fatigue in mouse diaphragm under low PO2. Accordingly, dihydrofluorescein (a fluorescent probe) was used to monito...

  14. The effect of oxygen on aldosterone release from bovine adrenocortical cells in vitro: PO2 versus steroidogenesis.

    Science.gov (United States)

    Raff, H; Kohandarvish, S

    1990-08-01

    Hypoxia decreases plasma aldosterone in vivo without a decrease in PRA, angiotensin II (ANG II), ACTH, or cortisol. The present study evaluated whether this could be due to a direct, specific inhibitory effect on the zona glomerulosa related to the magnitude of the decrease in oxygen (O2). Bovine adrenocortical cells were dispersed with collagenase and studied in vitro within 48 h. Cells were stimulated for 2 h with ANG II (0.1-1000 nM) or (Bu)2cAMP (0.3-3 mM) under oxygen levels ranging from 0 to 100% O2 (PO2 from 66 +/- 4 to 561 +/- 46 torr) vs. a reference gas mixture (21% O2 PO2 approximately 140 torr). Exposure to 123 +/- 8, 110 +/- 12, 100 +/- 16, and 66 +/- 4 torr led to 27%, 30%, 40% and 70% inhibition, respectively, of 3 nM ANG II-stimulated aldosterone secretion as compared to 140 +/- 16 torr (reference). Exposure to hyperoxia (288 +/- 36 to 561 +/- 46 torr) led to a small (10%) increase in ANG II-stimulated aldosterone secretion which was not statistically significant. The P50 (half-maximal PO2) for aldosteronogenesis was approximately 95 torr. The results for other doses of ANG II and for cAMP were similar. The inhibitory effect of low O2 was reversed by returning the cells to reference conditions (140 +/- 16 torr). Cortisol secretion was not significantly affected by changes in oxygen tension. We conclude that small changes in O2 within the physiological range directly and specifically inhibit aldosteronogenesis in a dose-dependent manner with a P50 of approximately 95 torr. Inhibition of cAMP-stimulated aldosterone secretion suggests a postreceptor site of action. This direct, reversible, and specific effect on the zona glomerulosa of the adrenal cortex may account for the dissociation of renin and aldosterone during hypoxia in vivo.

  18. Riparian Vegetation Mapping Along the Hanford Reach

    Energy Technology Data Exchange (ETDEWEB)

    FOGWELL, T.W.

    2003-07-11

    During the biological survey and inventory of the Hanford Site conducted in the mid-1990s (1995 and 1996), preliminary surveys of the riparian vegetation were conducted along the Hanford Reach. These preliminary data were reported to The Nature Conservancy (TNC), but were not included in any TNC reports to DOE or stakeholders. During the latter part of FY2001, PNNL contracted with SEE Botanical, the parties that performed the original surveys in the mid 1990s, to complete the data summaries and mapping associated with the earlier survey data. Those data sets were delivered to PNNL and the riparian mapping by vegetation type for the Hanford Reach is being digitized during the first quarter of FY2002. These mapping efforts provide the information necessary to create subsequent spatial data layers to describe the riparian zone according to plant functional types (trees, shrubs, grasses, sedges, forbs). Quantification of the riparian zone by vegetation types is important to a number of DOE'S priority issues including modeling contaminant transport and uptake in the near-riverine environment and the determination of ecological risk. This work included the identification of vegetative zones along the Reach by changes in dominant plant species covering the shoreline from just to the north of the 300 Area to China Bar near Vernita. Dominant and indicator species included Agropyron dasytachyudA. smithii, Apocynum cannabinum, Aristida longiseta, Artemisia campestris ssp. borealis var scouleriana, Artemisa dracunculus, Artemisia lindleyana, Artemisia tridentata, Bromus tectorum, Chrysothamnus nauseosus, Coreopsis atkinsoniana.

  20. Diffusive-to-ballistic transition of the modulated heat transport in a rarefied air chamber

    Full Text Available Modulated heat transfer in air subject to pressures from 760 Torr to 10-4 Torr is experimentally studied by means of a thermal-wave resonant cavity placed in a vacuum chamber. This is done through the analysis of the amplitude and phase delay of the photothermal signal as a function of the cavity length and pressure through of the Knudsen’s number. The viscous, transitional, and free molecular regimes of heat transport are observed for pressures P>1.5 Torr, 25 mTorrTorr, and P<25 mTorr; respectively. It is shown that the fingerprint of each regime is determined by the concavity of the amplitude decay in a length scan, which is concave upward for the viscous regime and concave downward in the free molecular one. Furthermore, the increase of the radiative contribution on both the amplitude and phase is also observed as the pressure reduces. The obtained results show that the proposed methodology can be used to study the molecular dynamics in gases supporting diffusive and ballistic heat transport.

    Runaway electron beam parameters and current-voltage characteristics of discharge in helium, hydrogen, and nitrogen at pressures in the range of several Torr to several hundred Torr have been studied. It is found that the maximum amplitudes of supershort avalanche electron beams (SAEBs) with a pulse full width at half maximum (FWHM) of ˜100 ps are achieved in helium, hydrogen, and nitrogen at a pressure of ˜60, ˜30, and ˜10 Torr, respectively. It is shown that, as the gas pressure is increased in the indicated range, the breakdown voltage of the gas-filled gap decreases, which leads to a decrease in the SAEB current amplitude. At pressures of helium within 20-60 Torr, hydrogen within 10-30 Torr, and nitrogen within 3-10 Torr, the regime of the runaway electron beam generation changes and, by varying the pressure in the gas-filled diode in the indicated intervals, it is possible to smoothly control the current pulse duration (FWHM) from ˜100 to ˜500 ps, while the beam current amplitude increases by a factor of 1.5-3.

    An experimental study has been carried out on the dynamical process taking place in the plasma generated by a TEA CO 2 laser (400 mJ, 100 ns) on a zinc target when surrounded by helium gas of pressure ranging from 2 Torr to 1 atm. Plasma characteristics were examined in detail on the emission lines of Zn I 481.0 nm and He I 587.6 nm by means of an unique time-resolved spatial distribution technique in addition to an ordinary time-resolved emission measurement technique. The results reveal, for the first time, persistent shock wave characteristics in all cases throughout the entire pressure range considered. Further analysis of the data has clarified the distinct characteristics of laser plasmas generated in different ranges of gas pressure. It is concluded that three types of shock wave plasma can be identified; namely, a target shock wave plasma in the pressure range from 2 Torr to around 50 Torr; a coupling shock wave plasma in the pressure range from around 50 Torr to 200 Torr and a gas breakdown shock wave plasma in the pressure range from around 200 Torr to 1 atm. These distinct characteristics are found to be ascribable to the different extents of the gas breakdown process taking place at the different gas pressures. These results, obtained for a TEA CO 2 laser, will provide a useful basis for the analyses of plasmas induced by other lasers. (author)

  3. Effect of water and nitrogen additions on free-living nitrogen fixer populations in desert grass root zones.

    In this study we measured changes in population levels of free-living N2-fixing bacteria in the root zones of potted Bouteloua eriopoda and Sporobolus flexuosus plants as well as the photosynthetic indices of the plants in response to added nitrogen, added water, and added water plus nitrogen treatments. In addition, N2 fixer population changes in response to added carbon source and nitrogen were measured in plant-free soil columns. There were significant increases in the numbers of N2 fixers associated with both plant species in the water and the water plus nitrogen treatments. Both treatments increased the photosynthetic index, suggesting that plant exudates were driving N2 fixer population changes. Population increases were greatest in the water plus nitrogen treatments, indicating that added nitrogen was synergistic with added water and suggesting that nitrogen addition spared bacteria the metabolic cost of N2 fixation, allowing greater reproduction. Plant-free column studies demonstrated a synergistic carbon-nitrogen effect when carbon levels were limiting (low malate addition) but not when carbon was abundant (high malate), further supporting this hypothesis. The results of this study indicate the presence of N2 fixer populations which interact with plants and which may play a role in the nitrogen balance of desert grasslands. PMID:8215373

    The impact of highly saline wetland ecosystem created under Salinity Control and Reclamation Project (SCARP) on floral diversity was investigated in the arid environments of Cholistan Desert. Species richness, diversity indices and evenness indices were worked out to look at the distance at which the salt water has altered the native vegetation. Four sites including SCARP ponds of different ages (S1, S2, S3 and S4), and a reference site (SR) were selected for vegetation studies and data were recorded by 1 x 1 m quadrats, which were laid on permanent transect lines. Salt water showed great influence on ecological parameters of the native vegetation up to 40 m. Multivariate (cluster) analysis showed close clustering of highly salt tolerant species, Aeluropus lagopoides, Tamarix dioica and Suaeda fruticosa in one group, and relatively less tolerant Crotalaria burhia, Cyperus conglomeratus, Indigofera argentea, Haloxylon salicornicum, Haloxylon stocksii, Neurada procumbens and Salsola baryosma in second group. Moderately salt tolerant Aristida adscensionis, Lasiurus scindicus and Sporobolus iocladus were clustered in a separate group. (author)

  5. Effects of Erosion from Mounds of Different Termite Genera on Distinct Functional Grassland Types in an African Savannah.

    A key aspect of savannah vegetation heterogeneity is mosaics formed by two functional grassland types, bunch grasslands, and grazing lawns. We investigated the role of termites, important ecosystem engineers, in creating high-nutrient patches in the form of grazing lawns. Some of the ways termites can contribute to grazing lawn development is through erosion of soil from aboveground mounds to the surrounding soil surface. This may alter the nutrient status of the surrounding soils. We hypothesize that the importance of this erosion varies with termite genera, depending on feeding strategy and mound type. To test this, we simulated erosion by applying mound soil from three termite genera ( Macrotermes , Odontotermes , and Trinervitermes ) in both a field experiment and a greenhouse experiment. In the greenhouse experiment, we found soils with the highest macro nutrient levels (formed by Trinervitermes ) promoted the quality and biomass of both a lawn ( Digitaria longiflora ) and a bunch ( Sporobolus pyramidalis ) grass species. In the field we found that soils with the highest micro nutrient levels (formed by Macrotermes ) showed the largest increase in cover of grazing lawn species. By linking the different nutrient availability of the mounds to the development of different grassland states, we conclude that the presence of termite mounds influences grassland mosaics, but that the type of mound plays a crucial role in determining the nature of the effects.

    Knowledge of oviposition sites selected by wetland mosquitoes could improve mosquito control and guide wetland rehabilitation practices to avoid creating or exacerbating a mosquito problem. Two studies that enumerated Aedes vigilax eggshells found in salt marsh soil on the western portion of Kooragang Island in New South Wales, Australia, allowed an evaluation of oviposition sites. In one study, the density of eggshells found in samples collected from a large area was related to environmental factors, including distance from nearby drainage channels, vegetation cover, elevation, and terrain characteristics. Multiple-regression analysis suggested eggshell densities were positively correlated with the presence of depressions and ponds, vegetation cover, and distance from culverts, but negatively related to elevation. In another study, eggshell density was related to relative elevation and vegetation species within each of two 400-m2 plots on Kooragang Island. In all but one instance, samples from bare soil contained fewer eggshells than samples with vegetation cover at both plots. Eggshell density did not differ between the two dominant vegetation species, Sarcocornia quinqueflora and Sporobolus virginicus, although bare soil of one plot had a mean eggshell density similar to that of soil with S. quinqueflora cover. Eggshells were at highest density at intermediate elevations at one plot but at low elevations at the other.

    Pappophorum vaginatum is the most abundant C4 perennial grass desirable to livestock in rangelands of northeastern Patagonia, Argentina. We hypothesized that (1) defoliation reduce net primary productivity, and root length density and weight in the native species, and (2) root net primary productivity, and root length density and weight, are greater in P. vaginatum than in the other, less desirable, native species (i.e., Aristida spegazzinii, A. subulata and Sporobolus cryptandrus). Plants of all species were either exposed or not to a severe defoliation twice a year during two growing seasons. Root proliferation was measured using the cylinder method. Cylindrical, iron structures, wrapped up using nylon mesh, were buried diagonally from the periphery to the center on individual plants. These structures, initially filled with soil without any organic residue, were dug up from the soil on 25 April 2008, after two successive defoliations in mid-spring 2007. During the second growing season (2008-2009), cylinders were destructively harvested on 4 April 2009, after one or two defoliations in mid-and/or late-spring, respectively. Roots grown into the cylinders were obtained after washing the soil manually. Defoliation during two successive years did reduce the study variables only after plants of all species were defoliated twice, which supported the first hypothesis. The greater root net primary productivity, root length den-sity and weight in P. vaginatum than in the other native species, in support of the second hypothesis, could help to explain its greater abundance in rangelands of Argentina.

    In order to understand the secondary productivity of macrobenthos in different botanic habitats in intertidal zone in Gaoqiao of Zhanjiang, the Brey's empirical formula was applied to calculate the secondary productivity based on the investigations in the habitats of Sonneratia apetala, Aegiceras corniculatum, Sporobolus virginicus, and Bruguiera conjugate in four seasons, 2010. The secondary productivity of the macrobenthos in the habitats in four seasons was averagely 11.77 g AFDM x m(-2) x a(-1), being the highest in S. apetala habitat (18.16 g AFDM x m(-2) x a(-1)), followed by in A. corniculatum habitat (17.67 g AFDM x m(-2) x a(-1)), S. virginicus habitat (8.34 g AFDM x m(-2) x a(-1)), and B. conjugate habitat (2.92 g AFDM x m(-2) x a(-1)). The P/B ratio of the macrobenthos was the highest in B. conjugate habitat (2.38), followed by in S. virginicus, S. virginicus, and A. corniculatum habitats, with the values of 1.23, 0.99, and 0.48, respectively. The differences in the secondary productivity and P/B ratio of the macrobenthos among the four botanic habitats were mainly related to the sediment total organic carbon, food type, and macrobenthos individual size.

    Coastal saltmarsh and their constituent components and processes are of an interest scientifically due to their ecological function and services. However, heterogeneity and seasonal dynamic of the coastal wetland system makes it challenging to map saltmarshes with remotely sensed data. This study selected four important saltmarsh species Pragmitis australis, Sporobolus virginicus, Ficiona nodosa and Schoeloplectus sp. as well as a Mangrove and Pine tree species, Avecinia and Casuarina sp respectively. High Spatial Resolution Worldview-2 data and Coarse Spatial resolution Landsat 8 imagery were selected in this study. Among the selected vegetation types some patches ware fragmented and close to the spatial resolution of Worldview-2 data while and some patch were larger than the 30 meter resolution of Landsat 8 data. This study aims to test the effectiveness of different classifier for the imagery with various spatial and spectral resolutions. Three different classification algorithm, Maximum Likelihood Classifier (MLC), Support Vector Machine (SVM) and Artificial Neural Network (ANN) were tested and compared with their mapping accuracy of the results derived from both satellite imagery. For Worldview-2 data SVM was giving the higher overall accuracy (92.12%, kappa =0.90) followed by ANN (90.82%, Kappa 0.89) and MLC (90.55%, kappa = 0.88). For Landsat 8 data, MLC (82.04%) showed the highest classification accuracy comparing to SVM (77.31%) and ANN (75.23%). The producer accuracy of the classification results were also presented in the paper.

    The reproductive effort of some annual and perennial plant species was investigated with respect to successional sequence, habitat conditions and plant size. in the psammosere succession (dune succession), the reproductive effort (RE) of Cressa cretica and A triplex griffithii was significantly greater in the early stage compared to that in late succession. Likewise, in relation to lithosere succession, Sporobolus arabicus. Pluchea lanceolata and Vernonia cenerescens all showed high reproductive effort in early part of succession compared to that of late succession. The annuals (S. arabicus and P lance/ala) exhibited greater reproductive effort compared to the perennial species Vernonia cinerescens. Examination of the Impact of site differences on reproductive effort showed that four grasses including Selaria intermedia, Chioris harbata, Cenchrus hiflorus, and Eragroslis pilosa were found to have significantly (P<0.05) greater reproductive effort in site 1 (near cultivated field), compared to site 2 (a vacant lot), which had low nutrient level compared to site 1. The reproductive effort of Sonclius asper (a composite) did not exhibit significant difference between sites. The investigation of relationships between plant size (volume) and reproductive effort of Solanuin forskalii, Senna holosericea and Heliolropium ophioglossum showed positive correlations between plant size and reproductive effort. Solanum forskalii and Senna holosericca, in particular, exhibited a close association in this respect. It is concluded that: 1) RE is greater in early compared to late succession, 2) RE changes with the habitat and 3) there seems to be a direct relationship between RE and plant size. (author)

    Grazing in patches of Cynodon dactylon and of Sporobolus spicatus by four large herbivores, and the interaction between these sedentary herbivores was studied in Lake Manyara National Park, northern Tanzania. The herbivores were the African buffalo, Syncerus caffer; the African elephan, Loxodonta africana; the Burchell's zebra, Equus burchelli; and the wildebeest, Connochaetus taurinus. Four different hypotheses of the interactions between the herbivores were tested, viz., increased predator detection/protection through association of species, facilitation of the food intake through the influence of other species, use by other species of the food manipulation strategy of buffalo, and interspecific competition for food. On the level of a single day, zebra and wildebeest were symbiotic, which could have been caused by an increased chance of predator detection. A similar association between buffalo and wildebeest or zebra was also detected on C. dactylon grasslands. There was no indication of facilitation between any of the herbivores. Buffalo had a despotic relationship with elephant, that is the elephant's consumption was lowered when buffalo had visited a patch prior to their arrival. When elephant and buffalo arrived at the same time there appeared to be scramble competition between them.Habitat overlap was calculated for four pairs of species. In conjunction with the analyses of the patch visits, it was concluded that a small overlap was associated with interspecific competition and a large habitat overlap was associated with symbiosis.

    To present a method for simultaneous acquisition of alveolar oxygen tension (P A O 2 ), specific ventilation (SV), and apparent diffusion coefficient (ADC) of hyperpolarized (HP) gas in the human lung, allowing reinterpretation of the P A O 2 and SV maps to produce a map of oxygen uptake (R). An imaging scheme was designed with a series of identical normoxic HP gas wash-in breaths to measure ADC, SV, P A O 2 , and R in less than 2 min. Signal dynamics were fit to an iterative recursive model that regionally solved for these parameters. This measurement was successfully performed in 12 subjects classified in three healthy, smoker, and chronic obstructive pulmonary disease (COPD) cohorts. The overall whole lung ADC, SV, P A O 2 , and R in healthy, smoker, and COPD subjects was 0.20 ± 0.03 cm 2 /s, 0.39 ± 0.06,113 ± 2 Torr, and 1.55 ± 0.35 Torr/s, respectively, in healthy subjects; 0.21 ± 0.03 cm 2 /s, 0.33 ± 0.06, 115.9 ± 4 Torr, and 0.97 ± 0.2 Torr/s, respectively, in smokers; and 0.25 ± 0.06 cm 2 /s, 0.23 ± 0.08, 114.8 ± 6.0Torr, and 0.94 ± 0.12 Torr/s, respectively, in subjects with COPD. Hetrogeneity of SV, P A O 2 , and R were indicators of both smoking-related changes and disease, and the severity of the disease correlated with the degree of this heterogeneity. Subjects with symptoms showed reduced oxygen uptake and specific ventilation. High-resolution, nearly coregistered and quantitative measures of lung function and structure were obtained with less than 1 L of HP gas. This hybrid multibreath technique produced measures of lung function that revealed clear differences among the cohorts and subjects and were confirmed by correlations with global lung measurements.

  13. A Spatial Control for Correct Timing of Gene Expression during the Escherichia coli Cell Cycle

    Directory of Open Access Journals (Sweden)

    Yuan Yao

    2016-12-01

    Full Text Available Temporal transcriptions of genes are achieved by different mechanisms such as dynamic interaction of activator and repressor proteins with promoters, and accumulation and/or degradation of key regulators as a function of cell cycle. We find that the TorR protein localizes to the old poles of the Escherichia coli cells, forming a functional focus. The TorR focus co-localizes with the nucleoid in a cell-cycle-dependent manner, and consequently regulates transcription of a number of genes. Formation of one TorR focus at the old poles of cells requires interaction with the MreB and DnaK proteins, and ATP, suggesting that TorR delivery requires cytoskeleton organization and ATP. Further, absence of the protein–protein interactions and ATP leads to loss in function of TorR as a transcription factor. We propose a mechanism for timing of cell-cycle-dependent gene transcription, where a transcription factor interacts with its target genes during a specific period of the cell cycle by limiting its own spatial distribution.

    The vacuum system for TFTR is described. Insofar as possible, conventional and ultrahigh vacuum (UHV) components and technology will be employed. Subassemblies will be prebaked in vacuum to reduce subsequent outgassing, and assembly will employ TIG welding and metal gaskets. It is not anticipated that the totally assembled torus with its numerous diagnostic appendages will be baked in situ to a high temperature, however a lower bakeout temperature (approximately 250 0 C) is under consideration. Final vacuum conditioning will be performed using discharge cleaning to obtain a specific outgassing rate of less than or = to 10 -10 Torr liter/sec cm 2 hydrogen isotopes and less than or = to 10 -12 Torr liter/sec cm 2 of other gases, and a base pressure of less than or = to 5 x 10 -8 Torr

    The convective flow structures in the vapor phase on earth are shown to be single unicellular, indicating the solutally dominant convection is important. These findings reflect that the total molar fluxes show asymmetrical patterns in a viewpoint of interfacial distributions. With decreasing the gravitational level form 1 g{sub 0} down to 1.0x10{sup -4} g{sub 0}, the total molar fluxes decay first order exponentially. It is also found that the total molar fluxes decay first order exponentially with increasing the partial pressure of component B, PB (Torr) form 5 Torr up to 400 Torr.. Under microgravity environments less than 1 g{sub 0}, a diffusive-convection mode is dominant and, results in much uniformity in front of the crystal regions in comparisons with a normal gravity acceleration of 1 g{sub 0}.

    Optically pumped rare gas lasers are being investigated as potential high-energy, high beam quality systems. The lasing medium consists of rare gas atoms (Rg=Ne, Ar, Kr, or Xe) that have been electric discharge excited to the metastable np 5 (n+1)s P3 2 state. Following optical excitation, helium (He) at pressures of 200-1000 Torr is used as the energy transfer agent to create a population inversion. The primary technical difficulty for this scheme is the discharge production of sufficient Rg* metastables in the presence of >200  Torr of He. In this Letter, we describe a pulsed discharge that yields >10 13   cm -3 Ar* in the presence of He at total pressures up to 750 Torr. Using this discharge, a diode-pumped Ar* laser providing 4.1 W has been demonstrated.

    Experiments are in progress on cryosorption pumping using a double-chevron pump with a molecular sieve pumping surface. Studies have been made with hydrogen, deuterium, helium, and deuterium-helium at 10 -7 to 3 x 10 -3 torr. Steady pumping speeds were observed for deuterium; above 10 -4 torr the speed increased with pressure until runaway occurred. At less than 10 -6 torr and low panel loading, hydrogen pumping speeds resemble those for deuterium. At higher pressures, the pump can function by condensation or sorption, and unsteady speeds are observed. Helium pumping is always by sorption, but regions of instability have been observed and defined. Deuterium-helium pumping tests showed that deuterium condensation on the panels prevents cryosorption of helium; however, compound pumps with separate panels for helium and hydrogen will be satisfactory

    Multi-walled carbon nanotubes (MWCNTs) are grown by arc discharge method in a controlled methane environment. The arc discharge is produced between two graphite electrodes at the ambient pressures of 100 torr, 300 torr, and 500 torr. Arc plasma parameters such as temperature and density are estimated to investigate the influences of the ambient pressure and the contributions of the ambient pressure to the growth and the structure of the nanotubes. The plasma temperature and density are observed to increase with the increase in the methane ambient pressure. The samples of MWCNT synthesized at different ambient pressures are analyzed using transmission electron microscopy, scanning electron microscopy, Raman spectroscopy, Fourier transform infrared spectroscopy, and X-ray diffraction. An increase in the growth of MWCNT and a decrease in the inner tube diameter are observed with the increase in the methane ambient pressure

A pure zinc target was used, and sputtering was carried out in an oxygen atmosphere. The working pressure was varied between 50 and 800 mTorr. XRD characterization showed that for a window of working pressures between 300 and 500 mTorr, the deposited films were polycrystalline, with strong preferential orientation of grains along the c-axis. The film deposited at 400 mTorr had the highest (002) peak with the largest estimated grain size. Outside this window, the crystallinity and c-orientation of grains are lost. The microstructure of the films was investigated by Atomic Force microscopy (AFM). Optical transparency of the films was about 85%. The films produced were highly resistive, which might provide new alternatives for the synthesis of ZnO thin films aimed for SAW devices.

    The main vacuum system of the Variable Energy Cyclotron which has been built indigenously has fulfilled the requirements for the smooth operation of the machine. By running two 88.9 cm diffusion pumps with freon cooled baffles and backed by 600 l/m rotary pumps, a pressure of 5 x 10 -6 torr in absence of the beam and 1 x 10 -5 torr in presence of the beam is readily achieved in the 23 m 3 volume. Various means have been adopted to maintain the system in order and contamination-free, by maintaining a pressure level of 1 x 10 -4 torr throughout the working week by a 30 cm diffusion pump, which can run even on emergency power. Cryopanels have also been installed and tried out. Details of pump-down characteristics and system performance are discussed. (auth.)
