    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.

    Full Text Available Systematic field sampling revealed that within 50 years since the first records in Slovenia, Sporobolus neglectus and S. vaginiflorus became widespread. They are two superficially similar N American annual grass species with cleistogamous spikelets and similar ecology that are confined to dry ruderal places in their European secondary range, especially along roads. The oldest records of naturalised populations of both species in Europe date back to the 1950s, when both were found for the first time in the Vipava valley (SW Slovenia. They spread slowly in the next decades to NE Italy, N Croatia, and S Austria until recently, when an explosive expansion has been observed along almost all the main roads in lowland and montane Slovenia. In addition to that, one or both of them have recently been recorded scattered in SE Europe (Hungary, Serbia, B&H, Montenegro and W Europe (France, Switzerland. Sporobolus vaginiflorus is herein reported for the first time for Serbia, Herzegovina (in B&H, and Slavonia (in Croatia.

    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.

    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.

    Drought and its affects on agricultural production is a serious issue facing global efforts to increase food supplies and ensure food security for the growing world population. Understanding how plants respond to dehydration is an important prerequisite for developing strategies for crop improvement in drought tolerance. This has proved to be a difficult task as all of the current research plant models do not tolerate cellular dehydration well and, like all crops, they succumb to the effects of a relatively small water deficit of -4MPa or less. For these reasons many researchers have started to investigate the usefulness of resurrection plants, plants that can survive extremes of dehydration to the point of desiccation, to provide answers as to how plants tolerate water loss. We have chosen to investigate the leaf proteome response of the desiccation-tolerant grass Sporobolus stapfianus Gandoger to dehydration to a water content that encompasses the initiation of the cellular protection response evident in these plants. We used a combination of two-dimensional Difference Gel Electrophoresis (2D-DIGE) and liquid chromatography-tandem-mass spectrometry to compare the proteomes of young leaves from hydrated plants to those dehydrated to approximately 30% relative water content. High-resolution 2D-DIGE revealed 96 significantly different proteins and 82 of these spots yielded high-quality protein assignments by tandem-mass spectrometry. Inferences from the bioinformatic annotations of these proteins revealed the possible involvement of protein kinase-based signaling cascades and brassinosteroid involvement in the regulation of the cellular protection response. Enzymes of glycolysis, both cytoplasmic and plastidic, as well as five enzymes of the Calvin cycle increased in abundance. However, the RuBisCO large subunit and associated proteins were reduced, indicating a loss of carbon fixation but a continued need to supply the necessary carbon skeletons for the

    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

  16. TORR system polishes oily water clean

    International Nuclear Information System (INIS)

    Mowers, J.

    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

    The health status of Australia's indigenous people remains the worst of any subgroup within the population, and there is little evidence of any significant improvement over the past two decades, a situation unprecedented on a world scale. Compared with non-indigenous Australians, adult life expectancy is reduced by 15-20 years, with twice the rates of mortality from heart disease, 17 times the death rate from diabetes and 10 times the deaths from pneumonia. Despite improvements in perinatal mortality, they continue to represent a major cause of death, with infant deaths up to 2.5 times higher than the general population. The problems of educational disadvantage and unemployment are reflected in twice the rates of smoking and high obesity levels. Seven percent of indigenous families are homeless, with many more in inadequate and overcrowded housing, sometimes lacking water or sewerage. Economic disadvantage is real: 23% worry about going without food. Nutritional deficiencies in children have resulted in failure to thrive, contributing greatly to the problems of pneumonia and infectious diseases. The remoteness and isolation of many Aboriginal communities limit education and employment opportunities. It is important to consider the historical context of Aboriginal and Torres Strait Islander people, in order to gain an understanding of current health problems. The impact of past policies and practices and the 'introduced diet' are reflected in the poor health outcomes described above. This session will explore some of the underlying historical, cultural, structural and political factors that can be linked to the current problems.

  20. [Muir-Torre syndrome and Turcot syndrome].

    Science.gov (United States)

    Velter, C; Caussade, P; Fricker, J-P; Cribier, B

    Lynch syndrome (LS) is a syndrome that carries a genetic predisposition to certain cancers associating, either in a single individual or in a family, a visceral tumour, mainly colorectal, with a high risk of other synchronous or metachronous cancers. LS is linked with mutations in the genes coding for proteins in the DNA repair system. Phenotypic variants of SL exist, including Muir-Torre syndrome (MTS) and Turcot syndrome (TS), both of which predispose to colorectal cancer. They may be distinguished by the presence of benign or malignant sebaceous tumours in MTS, and tumours of the central nervous system in TS. A 59-year-old man, with a history of right colon cancer at the age of 36 years, consulted for a nose lesion shown by histopathological examination to be a sebaceous tumour. Immunohistochemistry revealed loss of expression of proteins MSH2 and MSH6, strongly suggesting a diagnosis of MTS. Eight years earlier, the man's son had developed a fatal glioblastoma; given the paternal phenotype of MTS, the hypothesis of TS in the son is probable. This case suggests that several variants of Lynch syndrome may be seen within the same family. It raises the issue of screening for cerebral tumours in patients with MTS and in their family members, even though such a recommendation does not exist; current recommendations in fact consist primarily of gastrointestinal and gynaecological monitoring.

    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.

    Muir-Torre Syndrome is defined by the coexistence of sebaceous skin tumors and internal malignancies. Mutations in the DNA mismatch repair genes are found in the inherited form of the disease, resulting in the absence of crucial enzymes involved with DNA replication process. This case describes a patient with sebaceous adenoma and colorectal carcinoma, meeting the criteria for Muir-Torre Syndrome. The immunohistochemical analysis of the skin lesion was an important tool to confirm the diagnosis, as it revealed nuclear negativity for MSH2 and MSH6.

    Muir-Torre syndrome is a rare autosomal dominant genodermatosis characterized by the occurrence of sebaceous gland neoplasm associated with visceral malignancies. Most patients present with sebaceous adenomas, but cystic sebaceous neoplasms have been reported as specific markers of the syndrome. Gastrointestinal and genitourinary cancers are the most common internal malignancies. Colorectal cancer is the commonest visceral neoplasm in Muir-Torre syndrome patients. In this case report, we describe a rare case of Muir-Torre syndrome associated with colon cancer, and we demonstrate the important role of the dermatopathologist in alerting the clinician to the possibility of Muir-Torre syndrome when the diagnosis of sebaceous neoplasm is made.

    While human genetic research promises to deliver a range of health benefits to the population, genetic research that takes place in Indigenous communities has proven controversial. Indigenous peoples have raised concerns, including a lack of benefit to their communities, a diversion of attention and resources from non-genetic causes of health disparities and racism in health care, a reinforcement of "victim-blaming" approaches to health inequalities, and possible misuse of blood and tissue samples. Drawing on the international literature, this article reviews the ethical issues relevant to genetic research in Indigenous populations and considers how some of these have been negotiated in a genomic research project currently under way in a remote Aboriginal community. We consider how the different levels of Indigenous research governance operating in Australia impacted on the research project and discuss whether specific guidelines for the conduct of genetic research in Aboriginal and Torres Strait Islander communities are warranted.

    Muir-Torre syndrome (MTS), a cutaneous variant of Lynch syndrome, consists of hereditary predisposition to cutaneous tumours and gastrointestinal and gynaecological neoplasms, with autosomal dominant transmission. It is associated with mutations in genes coding for proteins in the DNA mismatch repair system. Herein, we report a case of a male patient presenting Waldenstrom's macroglobulinemia since the age of 50 and which, after the age of 65 years, developed into sebaceous tumours (5 sebaceous adenomas, 1 sebaceoma, 1 sebaceous carcinoma) and colonic lesions (4 adenomas). The clinical phenotype was consistent with MTS. Somatic analysis carried out on one sebaceous tumour showed instability of the microsatellites with loss of expression of MSH2 and MSH6 although constitutional genetic analysis showed no germline mutations known to be harmful. This noteworthy case raises a number of questions, including the possibility of association between STM and Waldenstrom's macroglobulinemia, which is discussed herein.

    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.

  13. Tests to Reduce TorreCat™ Technology to Practice

    Torrefaction is the thermal treatment of materials in the absence of oxygen in the temperature range of 200 to 300 °C and has been shown to improve handling and grinding properties, hydrophobicity, volatiles content, energy density, and combustion performance of renewable energy biomass feedstock materials. The disadvantages of torrefaction are its relative high cost compared to the low value input feedstock material and the energy that can be lost to volatized gases. This work will demonstrate a new technology developed by Advanced Torrefaction Systems (ATS), known as TorreCat™ Technology, that uses an oxidation catalyst in a closed system to combust and destroy volatile organic compounds (VOCs) and other byproducts produced in the torrefaction process. An oxidation catalyst is a substance, or a combination of substances, that accelerate the rate of a chemical reaction without being consumed by the reaction. Catalytic combustion is a reaction that occurs at temperatures 50% lower than traditional combustion, such that essentially no NOx is created. The output of the oxidation catalyst (flue gas) consists mainly of superheated steam and inert gases (carbon dioxide and nitrogen), which can be used for heat in the thermal treatment process. INL has previously developed a pilot-scale Continuous-Feed Thermal Treatment System (CFTTS) that has 10 kg/hr capacity but does not reform the flue gas to reduce environmental concerns or capture all available heat from the biomass material. Using the TorreCat™ technology in INL’s thermal treatment system will demonstrate increased thermal efficiencies during the treatment process as well as reduced environmental impact and clean-up costs. The objective of this project is to determine the effectiveness of the Torrecat™ technology to reform the flue gas and capture as much of its heat content as possible.

    Muir-Torre syndrome is a variant of Lynch syndrome, characterised by sebaceous neoplasia and/or keratoacanthomas associated with visceral malignancies. Muir-Torre syndrome is caused by germline mutations of one of the mismatch repair genes, frequently MSH2 and less frequently MLH1 and MSH6. Visceral malignancies associated with Muir-Torre syndrome and Lynch syndrome include colorectal, endometrial and other gastrointestinal, urological and gynaecological malignancies. Small numbers of Lynch syndrome-associated soft tissue sarcomas have been reported, but there are no reported cases of soft tissue sarcomas in Muir-Torre syndrome. In this study, we report a 74-year-old man with known Muir-Torre syndrome with confirmed MSH2 germline mutation, diagnosed with pleomorphic liposarcoma of the right buttock in a previous radiation field. The tumour showed loss of expression of MSH2 and MSH6 on immunohistochemistry. Immunohistochemistry on another pleomorphic liposarcoma in a different patient with no previous history of Muir-Torre syndrome or Lynch syndrome showed no loss of expression of mismatch repair proteins. This is the first report of Muir-Torre syndrome-associated sarcoma and the first case of post-radiation sarcoma in Lynch syndrome.

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.

    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.

This syndrome is considered to be a phenotypic variant of Lynch syndrome (or Human Non Polyposis Colorectal Cancer). Muir-Torre syndrome is a familial cancer syndrome defined as the association of an internal malignancy with cutaneous sebaceous tumors. It is a rare disease. In our knowledge, this case is the first reported skin lesion related to Muir-Torre syndrome, located on the breast and mimicking ulcerated breast cancer. Genetic counselling obviously has an important place in the management of this pathology. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    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 ...

    Sebaceous adenomas (SAs) are rare, benign sebaceous gland tumours of the eyelid. SAs may be associated with primary internal malignancies. This association is known as Muir-Torre Syndrome (MTS). The purpose of this study was to approximate the prevalence of SAs, to determine the reliability of the clinical diagnosis of SAs and to demonstrate immunohistochemical staining of DNA mismatch repair proteins mutL homologue 1 (MLH1) and mutS homologue 2 (MSH2) for a case of MTS. We reviewed the histopathology reports from all eyelid specimens collected between 1993 and 2013 at the Henry C Witelson Ocular Pathology Laboratory to determine the proportion of SAs. For the SAs identified on histopathology, we looked at patient charts to see what diagnosis was originally suspected on clinical examination. Immunohistochemical staining for MLH1 and MSH2 was performed on all SAs to screen for MTS. Of the 5884 eyelid specimens collected, 9 were SAs (6 women, 3 men; 42-72 years old). The diagnosis of SA was suspected clinically in only one of the nine cases based on the gross appearance of the eyelid lesion. Immunohistochemistry revealed one SA case with positive MLH1 expression and negative MSH2 expression. These findings prompted systemic work-up and this patient was diagnosed with MTS after discovery of a colon adenocarcinoma T2M0N0. The diagnosis of eyelid SA is rare. The importance of this benign eyelid tumour stems from its association with internal malignancies in MTS. Immunohistochemical staining of mismatch repair proteins MLH1 and MSH2 is a valid and accessible strategy for investigating MTS in patients with SAs. Published by the BMJ Publishing Group Limited.

    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.

    Muir-Torre syndrome is a rare genodermatosis inherited most frequently in an autosomal dominant fashion. Current criteria for its diagnosis include at least one sebaceous tumor and an underlying visceral malignancy. Muir-Torre syndrome is strongly associated with a germline mutation in DNA mismatch repair genes. We report two patients with a history of colorectal carcinoma who presented with sebaceous neoplasms on the face and trunk. Immunohistochemical staining of the sebaceous neoplasms demonstrated absence of mismatch repair proteins MSH2 and MSH6. Genetic studies confirmed deletions in the MSH2 gene, and a diagnosis of Lynch syndrome was made. Immunohistochemical staining for mismatch repair genes MLH1, MSH2, MSH6 and PMS2 may aid in the diagnosis of Muir-Torre syndrome in cases where there is high suspicion. Genetic testing is an important final step in the confirmation of Muir-Torre syndrome.

    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

    2017-07-01

    The intrusion in the Torres Strait of the Fly River plume polluted by mine tailings is an international water issue. To investigate the physical mechanisms involved in the intrusion process, numerical simulations were conducted to assess the relative influence of the bathymetry and the external forcing, namely the tides, the mean sea level slope across the strait, river runoff and wind forcing. The wind data from Horn Island, the only long-term wind station in the Torres Strait, is shown to be unreliable due to orographic effects. Mean sea level data from altimetry compare well with those from tide gauges in these shallow, reef-studded waters. The wind has a dominant effect on the mean sea level at seasonal and inter-annual periods. The resulting mean sea level difference across the strait fluctuated seasonally and strongly influenced the intrusion of the Fly River plume in the Torres Strait. The 3D finite-volume MOHID model reproduced the observation that the river plume starts by being stratified in the Gulf of Papua where it originates, and it mixes vertically when it enters the Torres Strait. The MOHID and the SLIM models were applied with different resolution to the Torres Strait and responded similarly to the external forcings. The predicted and observed Fly River plume intrusion in the eastern Torres Strait agreed well with each other, including the formation of patches due to flow reversals. However, the two models predicted a widely different Fly River plume in its far field in the western Torres Strait, the differences were attributed to the different bathymetry in the Australian and British-US bathymetry data for these poorly charted waters, which demonstrated the importance of the details of the bathymetry in controlling the extent of plume intrusion.

    Often, research activities in Torres Strait have not delivered full benefit to Torres Strait Islanders due to a lack of consultation, ineffectual communication of research information and lack of empathy for the needs of Islander communities. As for other stakeholder groups, integration of Islanders into the research process through practical involvement in research may overcome these problems. Three case studies from research projects conducted in Torres Strait are discussed to highlight a variety of communication and engagement activities carried out by non-Indigenous researchers. How these communication and extension activities facilitate collaboration between Torres Strait Islander and non-Indigenous researchers provides insight in the importance of these activities to the relative success of research projects. The benefits for Islanders in collaborating with researchers may be: improved understanding of the research and how it contributes to natural resource management; a sense of control in future management decisions; a greater likelihood of successful self-regulatory management systems; enhanced skills; and increased employment opportunities. The potential benefits for researchers are enhanced support for research projects resulting in increased access to data and logistic support that may ultimately impact the successful completion of projects. Such an approach will require researchers to take time to develop relationships with Torres Strait Islanders, effectively involve Islanders in research on an equitable basis and be flexible. This will ultimately require funding organisations to recognise the importance of such activities in research proposals and provide support through sufficient funding to enable these activities to be carried out.

    Grob, Alexandra; Feser, Christina; Grekin, Steven

    2016-01-01

    Muir-Torre syndrome is a rare, autosomal dominant genodermatosis characterized by the presence of at least one sebaceous gland neoplasm, associated with an underlying visceral malignancy. Muir-Torre syndrome is believed to be a subtype of Lynch Syndrome. Affected individuals are found to have germline mutations predominantly in DNA mismatch repair gene MSH2, and much less frequently, MLH1. The authors report the case of a 55-year-old woman presenting with multiple cutaneous neoplasms including sebaceoma, basal cell carcinoma, and squamous cell carcinoma; personal history of colorectal and endometrial cancer; and family history of colorectal cancer; found to have a deletion at mismatch repair gene MLH1. It is important to recognize the role of these less common gene deletions in producing the Muir-Torre syndrome phenotype, and consider the correlation of cutaneous manifestations with internal disease. The authors discuss the clinical presentation of Muir-Torre syndrome, methods of diagnosis, and the importance of regular medical surveillance to detect and prevent disease progression in Muir-Torre syndrome patients and their family members.

    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.

    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.

En el enfoque de su cosmovisión se toman en cuenta, por un lado, la relación entre filosofía, ciencia y religión, y, por otro, la concepción antropológica, mostrando la influencia de perspectivas filosóficas como el panteísmo y el positivismo. El estudio somete a crítica la desvinculación entre política y filosofía que hacía el propio de la Torre. Antes bien, concluye en que ambas esferas se encuentran conectadas y constituyen una raíz fundante del pensamiento latorrista.The article analyses Lisandro de la Torre's philosophical ideas. He was an important Argentinian politician, who had an active public life, mainly, as a legislator, between 1890 and 1937. The study is based upon some lectures and writings from his last years. His cosmological view is examined through the relation among philosophy, science and religion, on one hand, and through his anthropological account, on the other hand. The influence of pantheism and positivism is pointed out in both perspectives. It is criticised de la Torre's claim about politics as an anti-philosophical activity by arguing that philosophy and politics may be considered as foundations of his thought.

Presentamos el caso de un paciente masculino de 33 años, con antecedentes familiares de cáncer de colon, que consulta a nuestro servicio por lesión en cuero cabelludo de seis meses de evolución, con posterior diagnóstico histopatológico de adenoma sebáceo. Dentro de los exámenes complementarios se observan por colonoscopía, dos lesiones que correspondieron a adenocarcinomas de colon bien diferenciados. Con los antecedentes familiares, el examen clínico y la histopatología se efectúa el diagnóstico de síndrome de Muir-Torre.Muir-Torre syndrome represents the association of one or more sebaceous tumors, with one or more visceral malignancies and a family history of cancer. We report the case of a 33-year-old man, with a family history of colon cancer, who presented with a scalp tumor. The histopathological diagnosis was sebaceous adenoma. Two lesions were found in the colonoscopy, which corresponded to colon adenocarcionomas. With a compatible personal and family history of cancer and the results of the histopathology, we diagnosed the patient as Muir-Torre syndrome.

  18. Muir-Torre Syndrome and founder mismatch repair gene mutations: A long gone historical genetic challenge.

    Science.gov (United States)

    2016-09-10

    A "cancer predisposing syndrome" later labeled as Hereditary Non-Polyposis Colorectal Cancer (HNPCC) or Lynch Syndrome, was firstly described by Warthin, about one century ago. An increased predisposition to the development of multiple familial tumors is described as characteristic of this syndrome where visceral and cutaneous malignancies may appear at an early age namely endometrial, gastric, small bowel, ureteral and renal pelvis, ovarian, hepatobiliary tract, pancreatic, brain (Turcot Syndrome) and sebaceous glands (Muir-Torre Syndrome). The latter, a variant of Lynch Syndrome, is characterized by the presence of sebaceous skin adenomas, carcinomas and/or keratoacanthomas associated with visceral malignancies. Both Lynch Syndrome and Muir-Torre Syndrome have been recognized due to germline mutations in mismatch repair genes MLH1, MSH2 and MSH6. To date, 56 Lynch Syndrome founder mutations dependent on MLH1, MSH2 and, although less frequently found, MSH6 and PMS2 are described. Some of these founder mutations, principally of MSH2 gene, have been described to cause Muir-Torre phenotype and have been traced in large and outbreed Muir-Torre Syndrome families living in different US and European territories. Due to the evidences of highly specific Muir-Torre phenotypes related to the presence of widespread MSH2 founder mutations, preliminary search for these MSH2 common mutations in individuals carrying sebaceous tumors and/or keratoacanthomas, at early age or in association to visceral and familial tumors, permits cost-effective and time-saving diagnostic strategies for Lynch/Muir-Torre Syndromes.

    2012-12-01

    This is the first reported case of a sebaceous adenoma arising within an ovarian mature cystic teratoma in a patient with Muir-Torre syndrome. The pathologic findings and a literature review are presented, including the importance and possible benefits of an early diagnosis of Muir-Torre syndrome. It is proposed that the presence of a sebaceous adenoma in an ovarian cystic teratoma may serve as a useful trigger to consider further history and investigations, with the goal of identifying an important genetic cancer predisposition syndrome.

    Cardiovascular diseases (CVD) constitute the largest cause of death for Aboriginal and Torres Strait Islander people and remain the primary contributor to life expectancy differentials between Aboriginal and Torres Strait Islander and non-Indigenous Australians. As such, CVD remains the most critical target for reducing the life expectancy gap. The Essential Service Standards for Equitable National Cardiovascular Care for Aboriginal and Torres Strait Islander people (ESSENCE) outline elements of care that are necessary to reduce disparity in access and outcomes for five critical cardiovascular conditions. The ESSENCE approach builds a foundation on which the gap in life expectancy between Aboriginal and Torres Strait Islander and non-Indigenous Australians can be reduced. The standards purposefully focus on the prevention and management of CVD extending across the continuum of risk and disease. Each of the agreed essential service standards are presented alongside the most critical targets for policy development and health system reform aimed at mitigating population disparity in CVD and related conditions.

    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.

    To describe past attempts to quit smoking in a national sample of Aboriginal and Torres Strait Islander people, and to compare their quitting activity with that in the general Australian population. The Talking About The Smokes (TATS) 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 1643 smokers and 78 recent quitters between April 2012 and October 2013. Baseline results for daily smokers (n = 1392) are compared with results for daily smokers (n = 1655) from Waves 5 to 8.5 (2006-2012) of the Australian International Tobacco Control Policy Evaluation Project (ITC Project). Ever having tried to quit, tried to quit in the past year, sustained a quit attempt for 1 month or more. Compared with the general population, a smaller proportion of Aboriginal and Torres Strait Islander daily smokers had ever tried to quit (TATS, 69% v ITC, 81.4%), but attempts to quit within the past year were similar (TATS, 48% v ITC, 45.7%). More Aboriginal and Torres Strait Islander daily smokers than those in the general population reported sustaining past quit attempts for short periods only. Aboriginal and Torres Strait Islander smokers whose local health services had tobacco control resources were more likely to have tried to quit, whereas men and people who perceived they had experienced racism in the past year were less likely. Younger smokers, those who had gone without essentials due to money spent on smoking, and those who were often unable to afford cigarettes were more likely to have tried to quit in the past year, but less likely to have ever sustained an attempt for 1 month or more. Smokers who were unemployed, those who had not completed Year 12 and those from remote areas were also less likely to sustain a quit attempt. Existing comprehensive tobacco control programs appear to be motivating Aboriginal and Torres Strait Islander smokers

    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.

    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.

Subito attuò un’attenta costruzione della propria immagine, organizzando il viaggio verso la sede patriarcale secondo una precisa simbologia biblica ispirata alle figure di Salomone e Davide; arrivò nei territori del patriarcato e assunse ufficialmente il potere con due cerimonie d’entrata nella capitale religiosa, Aquileia, e in quella politica, Cividale. Per rafforzare il suo potere e ottenere la collaborazione dei sudditi unì concrete azioni di buon governo a un’ampia comunicazione politica che comprendeva cerimonie d’investitura feudale rivolte a nobili, ministeriali e prelati del patriarcato, e ai principi confinanti; cerimonie di liberazione dei servi di masnada; una rinascita economica e architettonica delle città del patriarcato, depresse dalla potente feudalità friulana, con la costruzione di torri, palazzi, castelli, vie, piazze, fontane e la concessione di privilegi; la fondazione di una nuova città chiamata Milano di Raimondo; il ricorso all’iconografia del potere, alle monete, alle opere tessili, alla poesia e al teatro. La comunicazione politica gli permise di sviluppare un rapporto positivo con i suoi interlocutori raggiungendo i suoi obiettivi e creando una solida immagine di sé come principe-patriarca di Aquileia.

    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.

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

    International Nuclear Information System (INIS)

    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

    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.

    This report outlines the major positive impacts of vaccines on the health of Aboriginal and Torres Strait Islander people from 2007 to 2010, as well as highlighting areas that require further attention. Hepatitis A disease is now less common in Aboriginal and Torres Strait Islander children than in their non-Indigenous counterparts. Hepatitis A vaccination for Aboriginal and Torres Strait Islander children was introduced in 2005 in the high incidence jurisdictions of the Northern Territory, Queensland, South Australia and Western Australia. In 2002–2005, there were 20 hospitalisations for hepatitis A in Aboriginal and Torres Strait Islander children agedtypes prior to vaccine introduction, the decline in total IPD notifications has been less marked in Aboriginal and Torres Strait Islander children than in other children. Higher valency vaccines (10vPCV and 13vPCV) which replaced 7vPCV from 2011 are likely to result in a greater impact on IPD and potentially also non-invasive disease, although disease caused by non-vaccine serotypes appears likely to be an ongoing problem. Among Aboriginal and Torres Strait Islander people aged ≥50 years, there have been recent increases in IPD, which appear related to low vaccination coverage and highlight the need for improved coverage in this high-risk target group. Since routine meningococcal C vaccination for infants and the high-school catch-up program were implemented in 2003, there has been a significant decrease in cases caused by serogroup C. However, the predominant serogroup responsible for disease remains serogroup B, and Aboriginal and Torres Strait Islander children have significantly higher incidence of serogroup B disease than other children. A vaccine against meningococcus type B has now been licensed in Australia. The decline in severe rotavirus disease after vaccine introduction in 2007 was less marked in Aboriginal and Torres Strait Islander children than in other children. By far the highest hospitalisation

    Full Text Available Según el Génesis de la Biblia (s.f., ed. 2009, la Torre de Babel fue construida por la humanidad para alcanzar el cielo, por lo que Yahvé confundió la lengua de los hombres. Este acontecimiento les llevó a dejar la torre inacabada y a que se marcharan en todas direcciones*; al parecer, esta es una realidad cuando se habla de calidad. En este texto se exponen las definiciones sobre calidad y otros conceptos relacionados, elaborados por autores emblemáticos del tema, incluyendo el impacto que esta noción tiene en el montaje de sistemas de gestión y formalización a través de procesos de certificación. En primera instancia, se aborda el concepto de calidad, incluyendo elementos históricos claves para su comprensión como la calidad en Japón, la calidad total, la calidad y la administración y los antecedentes del sistema de gestión. Luego se realiza una presentación de argumentos, base de la reflexión, que aportan a la necesidad imperiosa de la comprensión de la calidad, como asunto clave debido a su abordaje por presión o por voluntad, hacia un camino de certificación organizacional. Esto con el fin de abogar por la creación de un marco -campo- conceptual fortalecido que hoy se ha convertido en un paradigma, eliminando así la Torre de Babel que se pretende exponer

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°.

    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

    2011-06-01

    This communication focuses on respected older womens' ('Aunties') experiences of climate and other environmental change observed on Australia's Erub Island in the Torres Strait. By documenting these experiences, we explore the gendered nature of climate change, and provide new perspectives on how these environmental impacts are experienced, enacted and responded to. The way these adverse changes affect people and places is bound up with numerous constructions of difference, including gender. The responses of the Aunties interviewed to climate change impacts revealed Solastalgia; feelings of sadness, worry, fear and distress, along with a declining sense of self, belonging and familiarity.

    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

    Full Text Available The Torre de los Escipiones is a tower shape monument 6 km away from the city of Tarragona. Although it is incomplete, its good state of preservation makes it an iconic landmark of the area. It is an isolated construction in the landscape, which favours a certain misunderstanding. We believe it is necessary to develop a strategy to help its dissemination. In this case, the disclosure not only understood as the reconstruction of an hypothetical appearance in Roman times but also to imply the symbolic and social dimensions of Roman funerary world and how this is reflicted in its architecture. On the other hand, the Torre de los Escipiones has also been used as a study to test the ability of scientific research to connect with the disclosure to the public. That is, to develop from the working group itself the graphic sequence in which the work is shown: from the documentation of the remains to the analysis, interpretation and proposed restitution. Thus, not only the disclosure of the monument itself is achieved, but also demostrates how science contributes to the cultural enrichment of society.

    The extent to which existing and future research can impact on reducing health disparities relates not only to the evidence available, but the ability to find that evidence. Our objective is to quantify experts' literature searching effectiveness with respect to Aboriginal and Torres Strait Islander people's health. Nine journals were dual reviewed, and a 'gold standard' set of relevant articles was identified. Health librarians (n = 25) completed a standardised searching task using OVID MEDLINE, and results were compared with the gold standard. Sensitivity, specificity and precision rates were calculated. The gold standard comprised 136 of 1469 (9.3%) records from nine journals. Searches achieved a mean sensitivity of 53.2% (median = 64.7%, range 0.0-93.4%), specificity of 97.4% (median = 99.4%, range 52.6-100%) and precision of 83.3% (median = 91.0%, range 16.7-100%). Self-estimates of search sensitivity (post hoc) were significantly higher than observed (M = 78.9%, t = 4.812, P MEDLINE. A search filter may improve searching effectiveness for Aboriginal and Torres Strait Islander health literature. Assessment of health librarians' searching competencies warrants further professional debate and consideration. © 2013 The authors.

  1. 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

    To describe social normative beliefs about smoking in a national sample of Aboriginal and Torres Strait Islander people, and to assess the relationship of these beliefs with quitting. 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, 311 ex-smokers and 568 never-smokers from April 2012 to October 2013. Eight normative beliefs about smoking; wanting and attempting to quit. Compared with daily smokers in the general Australian population, Aboriginal and Torres Strait Islander daily smokers were less likely to report that mainstream society disapproves of smoking (78.5% v 62%). Among Aboriginal and Torres Strait Islander daily smokers, 40% agreed that Aboriginal and Torres Strait Islander community leaders where they live disapprove of smoking, 70% said there are increasingly fewer places they feel comfortable smoking, and most (90%) believed non-smokers set a good example to children. Support for the government to do more to tackle the harm caused by smoking was much higher than in the general Australian population (80% v 47.2%). These five normative beliefs were all associated with wanting to quit. Non-smokers reported low levels of pressure to take up smoking. Tobacco control strategies that involve the leadership and participation of local Aboriginal and Torres Strait Islander community leaders, particularly strategies that emphasise protection of others, may be an important means of reinforcing beliefs that smoking is socially unacceptable, thus boosting motivation to quit.

    Reticulated acanthoma with sebaceous differentiation (RASD) represents a rare benign cutaneous epithelial neoplasm with sebaceous differentiation. There has been much speculation about the relationship between RASD and Muir-Torre syndrome (MTS). We report a 53 year-old man who presented with RASD in addition to a prior history of sebaceous adenomas. Immunohistochemically, the tumour cells in the RASD and sebaceous adenomas showed a significantly reduced MSH6 protein expression, whereas there was no loss of MLH1, MSH2 and PMS2. This benign neoplasm, which can be mistaken for various other cutaneous lesions with sebaceous differentiation, deserves wider recognition for its possible association with MTS. © 2013 The Authors.

    Cross-Cultural Awareness Training has been seen as a way to improve nurses' knowledge and understanding of Indigenous peoples in Australia (Aboriginal and Torres Strait Islanders) and to therefore improve service delivery and therapeutic care to them. Nurses may have undertaken this type of training in their workplace or as part of nurse education in an undergraduate degree program. In asking Which Way in regards to this type of training and education, this paper includes the views of a selection of Aboriginal women and highlights the need to extend beyond Cross-Cultural Awareness Training to Anti-Racism Training. Furthermore, that Anti-Racism Training and addressing white race privilege is required in order to address the inequities within the health system, the marginalisation and disempowerment of Indigenous peoples.

    The antitumor activity of ethanol extract of Prosopis glandulosa Torr. (EPG) was evaluated against Ehrlich ascites carcinoma (EAC) tumor model in Swiss albino mice on dose dependent manner. The activity was assessed using survival time, average increase in body weight, hematological parameters and solid tumor volume. Oral administration of EPG at the dose of 100, 200 and 400 mg/Kg, significantly (p < 0.001) increased the survival time and decreased the average body weight of the tumor bearing mice. After 14 days of inoculation, EPG was able to reverse the changes in the hematological parameters, protein and PCV consequent to tumor inoculation. Oral administration of EPG was effective in reducing solid tumor mass development induced by EAC cells. The results indicate that EPG possess significant antitumor activity on dose dependent manner.

    Despite recognition of the extremely high rates of mental illness among custodial populations and the fact that Indigenous people represent around one-quarter of Australia's custodial population, little is known about the mental health of Aboriginal and Torres Strait Islander people in custody. Mental health is an important component of social and emotional wellbeing for Indigenous people and this paper considers current evidence regarding the mental health status of Indigenous Australians in custody. A systematic review was undertaken of the quantitative literature relating to the mental health problems of Indigenous people in custody in Australia. Despite high incarceration rates for Indigenous people and evidence that both mental health problems and rates of mental illness are extremely high in this group, studies in this area are few and limited in scope. The first step toward addressing the marked social and mental health problems for Indigenous people in custody is to systematically identify the nature and extent of these problems.

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.

    A 76-year-old white male with a history of adenocarcinoma of the rectosigmoideum and multiple colonic polyps removed at the age of 38 and 39 years by an abdominoperitoneal amputation and total colectomy, respectively, presented with multiple whitish and yellowish papules on the face and a verrucous lesion on the trunk. The lesions were surgically removed during the next 3 years and a total of 13 lesions were investigated histologically. The diagnoses included 11 sebaceous adenomas, 1 low-grade sebaceous carcinoma, and 1 squamous cell carcinoma. In some sebaceous lesions, squamous metaplasia, intratumoral heterogeneity, mucinous changes, and peritumoral lymphocytes as sometimes seen in sebaceous lesions in Muir-Torre syndrome were noted. Mutation analysis of the peripheral blood revealed a germline mutation c.692G>A,p.(Arg231His) in exon 9 and c.1145G>A, p.(Gly382Asp) in exon 13 of the MUTYH gene. A KRAS mutation G12C (c.34G>T, p.Gly12Cys) was detected in 1 sebaceous adenoma and a NRAS mutation Q61K (c.181C>A, p.Gln61Lys) was found in 2 other sebaceous adenomas. No germline mutations in MLH1, MSH2, MSH6 and PMS2 genes, no microsatellite instability, no aberrant methylation of MLH1 promoter, and no somatic mutations in MSH2 and MSH6 were found. An identical MUTYH germline mutation was found in the patient's daughter. Despite striking clinicopathological similarities with Muir-Torre syndrome, the molecular biologic testing confirmed the final diagnosis of MUTYH-associated polyposis.

    The University of Sydney's Graduate Diploma in Indigenous Health Promotion (GDIHP) and Masters of International Public Health (MIPH) students have expressed a consistent desire to engage more with each other through student tutorials or any small group activity. MIPH students have expressed an interest in learning about Aboriginal and Torres Strait Islander Aboriginal and Torres Strait Islanderpeople and their health issues recognising contextual similarities in health priorities and social-cultural determinants. A and TSI students enrolled in the GDIHP have traditionally had very little contact with other students and are often unaware of the innovative solutions implemented in developing countries. Through this inclusive teaching innovation the MIPH and GDIHP programmes utilised diversity in the student population and responded to the University's Strategic Plan to promote and enhance pathways for supporting Indigenous students. This innovation provided an opportunity for both groups to learn more about each other as they develop into globally competitive public health practitioners. The 'Beyond Borders' initiative exposed MIPH and GDIHP students to problem-based learning that incorporated global perspectives as well as focusing on the very specific and unique realities of life in Aboriginal and Torres Strait Islander communities. Both student cohorts reported that the knowledge and skill exchange was highly valuable and contributed to their development as health professionals. This simple yet effective initiative created a sustainable cross-cultural, interdisciplinary and community-oriented partnership that benefited all involved and assisted in addressing health inequities in Aboriginal and Torres Strait Islander communities and in developing countries.

    Muir-Torre syndrome represents a rare autosomal dominant familial cancer predisposition disorder defined by the occurrence of cutaneous sebaceous tumors and an internal malignancy, most commonly gastrointestinal carcinoma. Most examples of hereditary non-polyposis cancer syndrome (Lynch syndrome), including the Muir-Torre syndrome, are associated with microsatellite instability (MSI) and germline mutations in mismatch repair genes-most commonly MLH1 or MSH2. We present a 58-year-old man with Muir-Torre syndrome and a large retroperitoneal mass (14.3 cm in greatest dimension) encompassing the left adrenal gland. Sections showed a cellular malignant tumor composed of spindle cells with a high mitotic index and lacking morphologic evidence of adipocytic differentiation. It was weakly reactive for smooth muscle actin (SMA) and negative for desmin, CD117, CD31, CD34, S100 protein and pan-cytokeratin. Further immunohistochemical analysis revealed intact expression of MLH1 but loss of MSH2 in tumor nuclei. Compared to non-neoplastic tissue, the tumor showed MSI in five of seven dinucleotide markers. Fluorescence in situ hybridization (FISH) failed to reveal 12q15 amplification, effectively excluding dedifferentiated liposarcoma as a diagnostic consideration. This is a rare case of a patient with Muir-Torre syndrome who developed a related high-grade undifferentiated pleomorphic sarcoma as the associated internal malignancy. © 2013 John Wiley & Sons A/S.

    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

    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.

    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

    The Paraná-Etendeka Volcanic Province records the volcanism of the Early Cretaceous that precedes the fragmentation of the South-Gondwana supercontinent. Traditionally, investigations of these rocks prioritized the acquisition of geochemical and isotopic data, considering the volcanic stack as a monotonous succession of tabular flows. Torres Syncline is a tectonic structure located in southern Brazil and where the Parana-Etendeka basalts are well preserved. This work provides a detailed analysis of lithofacies and facies architecture, integrated to petrographic and geochemical data. We identified seven distinct lithofacies grouped into four facies associations related to different flow morphologies. The basaltic lava flows in the area can be divided into two contrasting units: Unit I - pahoehoe flow fields; and Unit II - simple rubbly flows. The first unit is build up by innumerous pahoehoe lava flows that cover the sandstones of Botucatu Formation. These flows occur as sheet pahoehoe, compound pahoehoe, and ponded lavas morphologies. Compound lavas are olivine-phyric basalts with intergranular pyroxenes. In ponded lavas and cores of sheet flows coarse plagioclase-phyric basalts are common. The first pahoehoe lavas are more primitive with higher contents of MgO. The emplacement of compound pahoehoe flows is related to low volume eruptions, while sheet lavas were emplaced during sustained eruptions. In contrast, Unit II is formed by thick simple rubbly lavas, characterized by a massive core and a brecciated/rubbly top. Petrographically these flows are characterized by plagioclase-phyric to aphyric basalts with high density of plagioclase crystals in the matrix. Chemically they are more differentiated lavas, and the emplacement is related to sustained high effusion rate eruptions. Both units are low TiO2 and have geochemical characteristics of Gramado magma type. The Torres Syncline main valley has a similar evolution when compared to other Large Igneous Provinces

    In 2012, the new profession of Aboriginal and Torres Strait Islander health practitioner (ATSIHP) was registered under the Health Practitioner Regulation National Law Act 2009. The project in this present study evolved out of the Australian Government\\'s recognition of the need for the existing Indigenous health worker (IHW) workforce to meet the minimum qualification requirements for registration as ATSIHPs through recognition of prior learning and/or further education. A total of 53 IHWs participated in the upskilling project between June 2014 and June 2015, with approximately 200 IHWs from Queensland expressing an interest in undertaking the training. This demonstrated a clear need for further training programs such as this one. The project was coordinated by the Indigenous Health Unit at James Cook University (JCU) with training being delivered by TAFE Cairns in collaboration with the College of Medicine and Dentistry, JCU. Students travelled from as far north as the Torres Strait and as far west as Mount Isa. The key issues for discussion were associated with the ATSIHP role being relatively new including the limited preparedness of training providers to deliver the upgraded qualification requirements and uncertainty about the registration process. Compounding this was a general undervaluing and underutilisation of the IHW role within the current primary healthcare system. Other challenges included the variations of IHW roles, scope of practice and educational standards held by individuals, as well as the associated complexities of providing training to IHWs from the large and diverse geographic area that is rural and remote Australia. Program and student evaluation was undertaken with each of the three cohorts via a course experience questionnaire, TAFE evaluation forms and opportunistic student feedback. Lessons learned as a result of this project include the need to continue to recognise and promote understanding of the contribution that IHW/ATSIHPs make

    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

    This article describes the use and effectiveness of the participatory action research (PAR) framework to better understand community members' perceptions and risks of pandemic influenza. In 2009, the H1N1 influenza pandemic affected Indigenous populations more than non-Indigenous populations in Oceania and the Americas. Higher prevalence of comorbidities (diabetes, obesity, asthma and chronic obstructive pulmonary disease) as well as pregnancy in Indigenous communities may have contributed to the higher risks of severe disease. Social disparity, institutionalised racism within health services and differences in access to culturally safe health services have also been reported as contributors to disadvantage and delayed appropriate treatment. Given these factors and the subsequent impact they had on Australian Aboriginal and Torres Strait Islander communities, the authors set out to ensure that the Australian national, state and territory pandemic plans adequately reflected the risk status of Aboriginal and Torres Strait Islander peoples and promoted meaningful engagement with communities to mitigate this risk. A national study explored the views of Aboriginal and Torres Strait Islander people and their experiences with H1N1 and used a qualitative PAR framework that was effective in gaining deep understandings from participants. Aboriginal and Torres Strait Islander community-controlled organisations and health services were involved in the implementation, interpretation and monitoring of this project. As a result, important features of the implementation of this PAR framework with Aboriginal and Torres Strait Islander communities and organisations emerged. These features included the importance of working in a multidisciplinary team with Aboriginal and Torres Strait Islander researchers; the complexities and importance of obtaining multi-site human research ethics approval processes; the importance and value of building the research capacity of both experienced and

    Full Text Available The purpose of the article is to analyze a document elaborated by a former National Museum of Rio de Janeiro Director, Heloisa Alberto Torres (1895-1977, who proposed to make a study of the state of affairs of the Natural Sciences and Anthropology in order to restructure the scientific research as a function of the Brazilian economic, political, and social development. The document was sent to the rector of the Universidade do Brasil, Pedro Calmon (1902-1985, in 1946, at the end of the Brazilian Estado Novo and the Second World War, when the Director was reconducted to the post she was in charge since 1938. According to the document the political role of the Natural Sciences and the Anthropology should be exerted in the theoretical limits of Ecology, which collided with the political demands of inordinate exploitation of the nartural resources. The Director's ideas ended up limited to institutional projects, carried out within the framework of the international scientific cooperation politics. This facilitated the circulation of scientists and benefited from national and foreign financial support.

  10. Corrosion assessment of reinforced concrete elements of Torre Velasca in Milan

    Full Text Available An assessment of corrosion conditions, aimed at the detection of the most suitable intervention method, of the reinforced concrete elements of Torre Velasca, which, from the late 1950s, characterises the skyline of the city centre of Milan, was carried out. The facades of the Tower are marked by the presence of structural elements coated with thick and dense layers of render and mortar. In-situ and laboratory analyses showed that the high thickness and compactness of the coating played a positive role in preventing the propagation of carbonation and of corrosion. It was estimated that after 50 years most rebars embedded in concrete were either still passive or free from actively-propagating corrosion. Hence it was concluded that most of the original concrete and coating could be preserved without further protection. However, this repair strategy could be compromised by the risk of loss of adhesion of the coating to the underlying concrete, and this crucial aspect should be better investigated in the design of the repair work.

    Sebaceous neoplasms such as adenoma, sebaceoma, and carcinoma, although sporadic in their occurrence, are clinically significant because of their association with Muir-Torre syndrome (MTS). MTS is a rare autosomal dominant genodermatosis characterized by the occurrence of sebaceous neoplasms and/or keratoacanthomas and visceral malignancies. MTS is usually the result of germline mutations in the DNA mismatch repair genes MSH2 and, albeit less commonly, MLH1. Although less know, MSH6 is yet another key player. Evidence from Lynch syndrome indicates that pathogenic germline mutations in MSH6 are typically microsatellite stable and have a clinical presentation that differs from that associated with germline mutations in MSH2 and/or MLH1. Given this unique mutator phenotype of MSH6, the primary aim of this review was to underscore the clinical manifestations associated with pathogenic mutations in MSH6 in patients with MTS. As the current clinical and laboratory work-up of MTS is geared toward patients harboring a germline mutation in MSH2 and/or MLH1, an additional aim was to provide a scaffolding for the work-up of a patient presenting with an isolated germline mutation in MSH6.

    Muir-Torre syndrome (MTS) is a rare genetic condition that predisposes individuals to skin tumors and visceral malignancies. Because of the potentially aggressive nature of internal malignancies and sebaceous carcinoma, and the tendency to have multiple low-grade visceral cancers, close cancer surveillance is required in individuals and their families with this usually autosomal dominant disorder. Although the majority of MTS is caused by mutations in DNA mismatch repair genes resulting in microsatellite instability, a newly described subtype of MTS does not demonstrate microsatellite instability and may be inherited in an autosomal recessive pattern. In addition, MTS may be unmasked in transplant recipients taking specific immunosuppressant drugs or other immunosuppressed patients. Neoplasms may be subject to immunohistochemistry or both immunohistochemistry and genetic testing to confirm the diagnosis of MTS. Here, we offer an update and an approach to the diagnosis and management of MTS with a particular emphasis on the role of immunohistochemistry and genetic testing.

    Sebaceous carcinoma of parotid gland are extremely rare with only 29 cases reported so far. The development of parotid sebaceous carcinoma in association with mutation in the mismatch repair gene that causes Muir Torre Syndrome (MTS), a subset of Lynch Syndrome, is still unclear. This study describes such a case and reviews the literature to see if an association between parotid sebaceous carcinoma and multiple visceral malignancies seen in Lynch Syndrome has ever been described. MTS represents a small subset of the Hereditary Non Polyposis Colorectal Carcinoma family, thought to be a subtype of Lynch Syndrome, where patients are prone to develop multiple visceral cancers involving gastrointestinal and genitourinary tract along with sebaceous and non-sebaceous tumours of the skin. MTS is a rare hereditary, autosomal dominant cancer syndrome caused by Microsatellite Instability and defect in DNA mismatch repair protein. The germline mutation involves mostly hMSH2 and hMLH1 genes. In MTS the skin of the head and neck area with the periocular region in particular, is affected but sebaceous carcinomas of the parotid associated with visceral malignancies has not yet been reported in literature. Here we report an index case of sebaceous carcinoma of parotid gland in a patient with MTS.

    Muir-Torre syndrome (MTS), a rare variant of the hereditary non polyposis colorectal cancer syndrome, is an autosomal dominant genodermatosis characterised by coincidence of sebaceous gland neoplasms (sebaceous adenoma, epithelioma, or carcinoma) and at least one internal malignancy. The underlying cause of MTS is a germline mutation in DNA mismatch repair genes MSH2, MLH1 and MSH6. We report the case of a 52-year-old caucasian woman with the development of metachronous colon cancer at the age of 38 years, uterine cancer at the age of 43 years, and unique occurrence of synchronous gastric and sebaceous carcinomas related to germline point mutation c. 2194A>T in the last exon of MLH1 gene, resulting in truncated protein in C-terminal region p. Lys732X due to premature stop codon. This mutation, not previously reported in MTS, disrupts the function of MutL complexes presumably by preventing the interaction with PMS1/PMS2 and impairing the endonuclease active site. This case points out the importance of sebaceous neoplasia, especially sebaceous adenocarcinoma, as cutaneous markers of MTS for timely implementation of cancer screening programs.

    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 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.

    Full Text Available With regard to world’s increasing demand for biologically active compounds, a novel source of xanthones and secoiridoid glycosides has been studied . Zeltnera beyrichii (Torr. & A. Gray Mans., an insufficiently acknowledged North American medicinal plant species, may be considered a pharmacological substitute for commercial C. erythraea Rafn, since it accumulates in aerial parts nearly the same amount of secoiridoid glycosides: swertiamarin, gentiopicrin, and sweroside (13.76, 7.56, and 0.17 mmol per 100 g dry weight, respectively in plants grown under greenhouse condition, and a considerable amount of xanthones: decussatin and eustomin. Additionally, Z. beyrichii produced as much biomass during cultivation in RITA ® temporary immersion bioreactors as greenhouse-grown plants, in a third of the time. Plants grown in bioreactors contained moderate levels of total phenolics and total flavonoids, and possessed modest antioxidant activity and antimicrobial potential against eight bacterial and eight fungal species. Therefore, this species may be highly recommended for cultivation either in natural environment, or in bioreactors under in vitro conditions, for producing compounds of interest of modern pharmacology and food industry.

    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.

    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.

    Adverse pregnancy outcomes are more common among Aboriginal and Torres Strait Islander populations than non-Indigenous populations in Australia. Later in life, most of the difference in life expectancy between Aboriginal and Torres Strait Islander women and non-Indigenous women is due to non-communicable diseases (NCDs). Most Aboriginal and Torres Strait Islander women attend health services regularly during pregnancy. Providing high-quality care within these appointments has an important role to play in improving the current and future health of women and babies. This study engaged stakeholders in a theory-informed process to use aggregated continuous quality improvement (CQI) data to identify 1) priority evidence-practice gaps in Aboriginal and Torres Strait Islander maternal health care, 2) barriers and enablers to high-quality care, and 3) strategies to address identified priorities. Three phases of reporting and feedback were implemented using de-identified CQI data from 91 health services between 2007 and 2014 (4,402 client records). Stakeholders (n = 172) from a range of professions and organisations participated. Stakeholders identified four priority areas relating to NCDs: smoking, alcohol, psychosocial wellbeing and nutrition. Barriers or enablers to high-quality care included workforce support, professional development, teamwork, woman-centred care, decision support, equipment and community engagement. Strategies to address the priorities included upskilling staff to provide best practice care in priority areas, advocating for availability of healthy food, housing and local referral options, partnering with communities on health promotion projects, systems to facilitate continuity of care and clear referral pathways. This novel use of large-scale aggregate CQI data facilitated stakeholder input on priority evidence-practice gaps in maternal health care in Australia.

    The Torres Indigenous Hip Hop Project (the Project) was conducted in the Torres and Northern Peninsula Area of Queensland during early 2010. 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.

    Full Text Available The aim of this paper is to assess the strength and weakness factors of post-industrial cities located in the Gulf of Naples in order to propose the most effective regeneration strategies towards a sustainable development of the urban coastline. This paper focuses on the city of Torre Annunziata and in particular on its industrial port area and waterfront. The analysis suggests that a sustainable development would be possible through the redesign and new functionalization of the waterfront and port area, improving resilience and creativity in order to integrate economic growth, ecological preservation and social opportunities. Thus, this paper is a proposal for a participative approach to the regeneration of the urban waterfront, enhancing the creative potential of the city and developing a new image for the waterfront that could become the strategic vision for a future economic, environmental and cultural development. A comparison between the waterfronts of Torre Annunziata and La Spezia has been carried out in order to assess what are the most effective choices for the future of Torre Annunziata, followed by an applicative process based on interviews.

    Objective: Effective interventions to improve population and individual health require environmental change as well as strategies that target individual behaviours and clinical factors. This is the basis of implementing an ecological approach to health programs and health promotion. For Aboriginal People and Torres Strait Islanders, colonisation has made the physical and social environment particularly detrimental for health. Methods and Results: We conducted a literature review to identify Aboriginal health interventions that targeted environmental determinants of health, identifying 21 different health programs. Program activities that targeted environmental determinants of health included: Caring for Country; changes to food supply and/or policy; infrastructure for physical activity; housing construction and maintenance; anti-smoking policies; increased workforce capacity; continuous quality improvement of clinical systems; petrol substitution; and income management. Targets were categorised according to Miller’s Living Systems Theory. Researchers using an Indigenous community based perspective more often identified interpersonal and community-level targets than were identified using a Western academic perspective. Conclusions: Although there are relatively few papers describing interventions that target environmental determinants of health, many of these addressed such determinants at multiple levels, consistent to some degree with an ecological approach. Interpretation of program targets sometimes differed between academic and community-based perspectives, and was limited by the type of data reported in the journal articles, highlighting the need for local Indigenous knowledge for accurate program evaluation. Implications: While an ecological approach to Indigenous health is increasingly evident in the health research literature, the design and evaluation of such programs requires a wide breadth of expertise, including local Indigenous knowledge.

    To compare the use of sleep diagnostic tests, the risks, and cofactors, and outcomes of the care of Indigenous and non-indigenous Australian adults in regional and remote Australia in whom sleep related breathing disorders have been diagnosed. A retrospective cohort study of 200 adults; 100 Aboriginal and Torres Strait Islander and 100 non-indigenous adults with a confirmed sleep related breathing disorder diagnosed prior to September 2011 at Alice Springs Hospital and Cairns Hospital, Australia. Results showed overall Indigenous Australians were 1.8 times more likely to have a positive diagnostic sleep study performed compared with non-indigenous patients, 1.6 times less likely in central Australia and 3.4 times more likely in far north Queensland. All regional and remote residents accessed diagnostic sleep studies at a rate less than Australia overall (31/100,000/y (95% confidence interval, 21-44) compared with 575/100,000/y). The barriers to diagnosis and ongoing care are likely to relate to remote residence, lower health self-efficacy, the complex nature of the treatment tool, and environmental factors such as electricity and sleeping area. Indigeneity, remote residence, environmental factors, and low awareness of sleep health are likely to affect service accessibility and rate of use and capacity to enhance patient and family education and support following a diagnosis. A greater understanding of enablers and barriers to care and evaluation of interventions to address these are required.

    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.

    A new potent antiinfective and antiparasitic 2,3-dihydro-1H-indolizinium chloride, (1), was isolated from Prosopis glandulosa Torr. var. glandulosa. Three additional new (2–4) and one known (5), indolizidines were also isolated, and the dihydrochloride salts of 1–3 (compounds 6, 7 and 8) were prepared. Structures were determined by 1D and 2D NMR and mass spectra. Compound 1 showed potent in vitro antifungal activity against Cryptococcus neoformans and Aspergillus fumigatus (IC50 values = 0.4 and 3.0 μg/mL, respectively), and antibacterial activity against methicillin-resistant Staphylococcus aureus and Mycobacterium intracellulare (IC50 values of 0.35 and 0.9 μg/mL, respectively). The remarkable in vitro fungicidal activity of 1–4 against C. neoformans (MFCs = 0.63→1.25 μg/mL) and 2, 3, and 5 against A. fumigatus (MFCs = 0.63→2.5 μg/mL) were similar to amphotericin B, but >2–4-fold more potent than 6–8. Prosopilosidine (1) showed potent in vivo activity at 0.0625 mg/Kg/day/ip for 5 days in a murine model of cryptococcosis by eliminating ~76% of C. neoformans infection from brain tissue compared to ~83% with amphotericin B at 1.5 mg/Kg/day. Compounds 1 and 4 exhibited potent activity and high selectivity index (SI) values against chloroquine sensitive (D6) and chloroquine resistant (W2) strains of Plasmodium falciparum with IC50 values of 39 and 95 ng/mL, and 42 and 120 ng/mL, respectively; (chloroquine, IC50 = 17 and 140 ng/mL).

    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 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

The three project versions will be discussed and described, also explaining how the structure and the traces of the process of building are the genesis and story of this work.La obra del arquitecto almeriense Fernando Cassinello Pérez ha sido escasamente publicada, pero lo cierto es que construyó mucho y bien. Su vida descansa sobre tres pilares: la producción arquitectónica, la actividad académica y la inquietud investigadora. Aquí se expondrá su última obra: las Tres Torres trillizas Star-Building (1975 que construyó frente al Paseo Marítimo de Almería, en el barrio de El Zapillo; y que son un elegante ejercicio residencial de investigación formal y sinceridad estructural. También son un ejemplo de cómo, desde la renuncia y con una densidad moderada, es posible construir interesantes propuestas de viviendas –orientadas al turismo– en la primera línea de playa. Y que, desde luego, merecen ser conocida por quien decida hoy proyectar y construir arquitectura colectiva. Se analizarán y describirán las tres versiones del proyecto; y se explicará cómo la estructura y las huellas del proceso de construcción son la génesis y el argumento de esta obra.

    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 Adverse pregnancy outcomes are more common among Aboriginal and Torres Strait Islander populations than non-Indigenous populations in Australia. Later in life, most of the difference in life expectancy between Aboriginal and Torres Strait Islander women and non-Indigenous women is due to non-communicable diseases (NCDs. Most Aboriginal and Torres Strait Islander women attend health services regularly during pregnancy. Providing high-quality care within these appointments has an important role to play in improving the current and future health of women and babies.This study engaged stakeholders in a theory-informed process to use aggregated continuous quality improvement (CQI data to identify 1 priority evidence-practice gaps in Aboriginal and Torres Strait Islander maternal health care, 2 barriers and enablers to high-quality care, and 3 strategies to address identified priorities.Three phases of reporting and feedback were implemented using de-identified CQI data from 91 health services between 2007 and 2014 (4,402 client records. Stakeholders (n = 172 from a range of professions and organisations participated.Stakeholders identified four priority areas relating to NCDs: smoking, alcohol, psychosocial wellbeing and nutrition. Barriers or enablers to high-quality care included workforce support, professional development, teamwork, woman-centred care, decision support, equipment and community engagement. Strategies to address the priorities included upskilling staff to provide best practice care in priority areas, advocating for availability of healthy food, housing and local referral options, partnering with communities on health promotion projects, systems to facilitate continuity of care and clear referral pathways.This novel use of large-scale aggregate CQI data facilitated stakeholder input on priority evidence-practice gaps in maternal health care in Australia.

    Aboriginal and Torres Strait Islander people experience higher levels of psychological distress and mental ill health than their non-Indigenous counterparts, but underuse mental health services. Interventions are required to address the structural and functional access barriers that cause this underuse. In 2012, the Southern Queensland Centre of Excellence in Aboriginal and Torres Strait Islander Primary Health Care employed a psychologist and a social worker to integrate mental health care into its primary health care services. This research study examines the impact of this innovation. A mixed-method research design was used whereby a series of qualitative open-ended interviews were conducted with 7 psychology clients, 5 social work clients, the practice dietician, and the social worker and psychologist. General practitioners, practice nurses, Aboriginal Health Workers and receptionists participated in 4 focus groups. Key themes were identified, discussed, refined and agreed upon by the research team. Occasions of service by the psychologist and social worker were reviewed and quantitative data presented. Clients and staff were overwhelmingly positive about the inclusion of a psychologist and a social worker as core members of a primary health care team. In one-year, the psychologist and social worker recorded 537 and 447 occasions of service respectively, and referrals to a psychologist, psychiatrist, mental health worker or counsellor increased from 17% of mental health clients in 2010 to 51% in 2012. Increased access by Aboriginal and Torres Strait Islander people to mental health care was related to three main themes: (1) Responsiveness to community needs; (2) Trusted relationships; and (3) Shared cultural background and understanding. The holistic nature and cultural safety of the primary health care service, its close proximity to where most people lived and the existing trusted relationships were identified as key factors in decreasing barriers to access

    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.

    The Muir-Torre syndrome variant of Lynch syndrome is characterized by the presence of sebaceous neoplasms (adenoma, epithelioma/sebaceoma, carcinoma) and Lynch syndrome-associated cancers (colon, endometrial, and others). Several clinical scoring systems have been developed to identify patients with colon cancer at high risk of Lynch syndrome. However, no such system has been described for patients presenting with sebaceous neoplasms. Based on logistic regression analysis, a scoring system was developed for patients with sebaceous neoplasm to identify those with the highest likelihood of having Muir-Torre syndrome. The final version of the scoring system included variables such as age at presentation of initial sebaceous neoplasm, total number of sebaceous neoplasms, personal history of a Lynch-related cancer, and family history of Lynch-related cancers. Patients with a score of 3 or more were more likely to have Muir-Torre syndrome (28 of 29 patients), those with a score of 2 had intermediate likelihood (12 of 20 patients), and no patient with a score of 0 or 1 was diagnosed with Muir-Torre syndrome. The Mayo Muir-Torre syndrome risk scoring system appears to identify whether patients who present with sebaceous neoplasms are in need of further Lynch syndrome evaluation using easily ascertained clinical information. Abnormal mismatch repair gene immunohistochemistry of a sebaceous neoplasm is a poor predictor in regard to diagnosing Lynch syndrome.

    Since the late 1990s, rising sea levels around the Torres Islands (north Vanuatu, southwest Pacific) have caused strong local and international concern. In 2002-2004, a village was displaced due to increasing sea incursions, and in 2005 a United Nations Environment Programme press release referred to the displaced village as perhaps the world's first climate change "refugees." We show here that vertical motions of the Torres Islands themselves dominate the apparent sea-level rise observed on the islands. From 1997 to 2009, the absolute sea level rose by 150 + /-20 mm. But GPS data reveal that the islands subsided by 117 + /-30 mm over the same time period, almost doubling the apparent gradual sea-level rise. Moreover, large earthquakes that occurred just before and after this period caused several hundreds of mm of sudden vertical motion, generating larger apparent sea-level changes than those observed during the entire intervening period. Our results show that vertical ground motions must be accounted for when evaluating sea-level change hazards in active tectonic regions. These data are needed to help communities and governments understand environmental changes and make the best decisions for their future.

    Muir-Torre syndrome is a rare, autosomal dominant condition characterized by the presence of a skin tumor of sebaceous differentiation and visceral malignancies. We reviewed the case of a 46-year-old Chinese man who had a bleeding mass over the right upper eyelid. He had a history of colon cancer and a family history satisfying the Amsterdam criteria for hereditary non-polyposis colorectal cancer syndrome with germline mutation in the MutS homolog-2 gene. The eyelid lesion was excised completely and submitted for histopathologic examination which showed sebaceous carcinoma. Frozen section and conjunctival map biopsy showed no residual malignancy or local metastasis. Post-operative positron-emission tomography with combined computed tomography did not reveal any residual or visceral malignancy. He had no recurrence in the 32-month follow-up period. We should consider Muir-Torre syndrome in patients with sebaceous carcinoma, especially in the presence of personal and/or family history of visceral malignancies.

    This article reports an unusual case of aggressive extraocular sebaceous carcinoma located on the scalp with subsequent usurpation of the bone and penetrating through the bone and meninges to the brain in a 56-year-old man affected by Muir-Torre syndrome. Microscopically, the sebaceous neoplasm was located in the middle to deep dermis without any connection to the epidermis and showed a multinodular growth with neoplastic nodules with a central comedo-type necrosis separated from each other by fibrovascular stroma. The nodules were composed of varying proportions of mature sebaceous cells and atypical basaloid cells with high degree of atypia, including high nuclear/cytoplasmic ratio, nuclear pleomorphism, macronucleoli, atypical mitoses, and necrosis. The neoplasm was totally removed. Histopathological examinations of the recurrent lesion showed identical morphological features and, in addition, signs of the tumors growing through the periosteum were noted. In the final excision specimen, both the dura mater and the brain tissue were infiltrated by the sebaceous carcinoma. The diagnosis of Muir-Torre syndrome was confirmed by molecular genetic investigation that revealed an identical germline mutation in MSH2 gene in several family members, some of whom had colorectal tumors.

  5. 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.

    To describe the research methods and baseline sample of the Talking About The Smokes (TATS) project. 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

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.

    An ultrahigh-vacuum tribometer for use in a ball-on-disk configuration was specially designed for measuring the friction and endurance life of magnetron-sputtered solid lubricating MoS(x) films deposited on sputter-cleaned 400 C stainless-steel disks, when slid against a 6-mm-diameter 440 C stainless-steel ball. The results of tests showed that the tribometer performs satisfactorily in unidirectional rotation in vacuum at a pressure of 10 exp -7 Pa, 10 exp -9 torr. Similarities are observed in the life cycle friction behavior and the coefficient of friction as a function of the number of disk revolutions, for MoS(x) films at average Hertzian contact from 0.33 to 0.69 GPa.

    1974-01-01

    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.

    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.

    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

    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.

    The extensive sea grass meadows in Torres Strait enable it to be a globally important habitat for the dugong, Dugong dugon, a marine mammal of cultural and dietary significance to Torres Strait Islanders and the basis for the substantial island-based fishery in the Torres Strait Protected Zone. Torres Strait sea grass communities are subjected to episodic diebacks which are now believed to be largely natural events. Information on dugong life history was obtained from specimens obtained from female dugongs as they were butchered for food by Indigenous hunters at two major dugong hunting communities in Torres Strait: Daru (9.04°S, 143.21°E) in 1978-1982 (a time of sea grass dieback and recovery) and Mabuiag Island (9.95°S, 142.15°E) in 1997-1999 (when sea grasses were abundant). Dugongs sampled in 1997-1999 had their first calf at younger ages (minimum of 6 cf. 10 years), and more frequently (interbirth interval based on all possible pregnancies 2.6±0.4 (S.E.) yr cf. 5.8±1.0 yr) than the dugongs sampled in 1978-1982. Pregnancy rates increased monotonically during 1978-1982, coincident with sea grass recovery. The age distribution of the female dugongs collected in 1997-1999 also suggested a low birth rate between 1973 and 1983 and/or or a high level of mortality for animals born during this period. These results add to the evidence from other regions that the life history and reproductive rate of female dugongs are adversely affected by sea grass loss, the effect of which cannot be separated from a possible density-dependent response to changes in dugong population size. Many green turtles in Torres Strait were also in poor body condition coincident with the 1970s sea grass dieback. The impacts of future sea grass diebacks need to be anticipated when management options for the traditional Torres Strait fisheries for dugongs and green turtles are evaluated.

  20. SALINITY AND SODICITY INTERACTIONS OF WEATHERED MINESOILS IN NORTHWESTERN NEW MEXICO AND NORTH EASTERN ARIZONA

    2006-05-01

    Weathering characteristics of minesoils and rooting patterns of key shrub and grass species were evaluated at sites reclaimed for 6 to 14 years from three surface coal mine operations in northwestern New Mexico and northeastern Arizona. Non-weathered minesoils were grouped into 11 classifications based on electrical conductivity (EC) and sodium adsorption ratio (SAR). Comparisons of saturated paste extracts, from non-weathered and weathered minesoils show significant (p < 0.05) reductions in SAR levels and increased EC. Weathering increased the apparent stability of saline and sodic minesoils thereby reducing concerns of aggregate slaking and clay particle dispersion. Root density of four-wing saltbush (Atriplex canascens), alkali sacaton (Sporobolus airoides), and Russian wildrye (Psathyrostachys junceus) were nominally affected by increasing EC and SAR levels in minesoil. Results suggest that saline and sodic minesoils can be successfully reclaimed when covered with topsoil and seeded with salt tolerant plant species.

    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.

    In Portugal human and canine leishmaniasis are caused by Leishmania infantum, and Phlebotomus perniciosus and P. ariasi are the proven vectors. Three main foci were identified in eighty's decade: Trás-os-Montes and Alto Douro region, Lisbon region and Algarve region, but according to OnLeish observatory data, canine leishmaniasis cases have been reported from several other regions, for which sand fly species and their infection rates are unknown. This study is the first phlebotomine survey in Torres Novas municipality, Santarém District, Portugal. The main objectives were to identify the phlebotomine species, their bioecological aspects, Leishmania infection rate and the risk factors for the presence of phlebotomine species in the municipality. From June to November, 2010, 275 biotopes were surveyed with CDC light-traps. Captures covered the 17 parishes of the municipality and included domestic, peridomestic and sylvatic biotopes. Specimens were identified morphologically and females were used for molecular detection of Leishmania and bloodmeal identification. Simple and multiple logistic regression analysis were used to identify risk factors for phlebotomine presence. Nonparametric tests were used to compare densities of independent groups. A total of 1262 sand flies were captured and identified, and four species detected: P. perniciosus (73.69%), P. ariasi (8.16%), P. sergenti (6.58%) and Sergentomyia minuta (11.57%). In 71.4% localities at least one L. infantum proven vector species was present. Risk factors were identified as: high average temperatures and low relative humidities, sheltered locations and absence of strong wind, presence of pine trees as dominant vegetation, peridomestic biotopes, particularly sheep pens or proximity of sheep, poultry and house martin nests. L. infantum infection rate was 4% for P. ariasi and 0.48% for the total of Larroussius females. P. perniciosus females exhibited an opportunistic behavior, feeding in a wide variety of

    Full Text Available Abstract Background Australian federal and jurisdictional governments are implementing ambitious policy initiatives intended to improve health care access and outcomes for Aboriginal and Torres Strait Islander people. In this qualitative study we explored Aboriginal Medical Service (AMS staff views on factors needed to improve chronic care systems and assessed their relevance to the new policy environment. Methods Two theories informed the study: (1 ‘candidacy’, which explores “the ways in which people’s eligibility for care is jointly negotiated between individuals and health services”; and (2 kanyini or ‘holding’, a Central Australian philosophy which describes the principle and obligations of nurturing and protecting others. A structured health systems assessment, locally adapted from Chronic Care Model domains, was administered via group interviews with 37 health staff in six AMSs and one government Indigenous-led health service. Data were thematically analysed. Results Staff emphasised AMS health care was different to private general practices. Consistent with kanyini, community governance and leadership, community representation among staff, and commitment to community development were important organisational features to retain and nurture both staff and patients. This was undermined, however, by constant fear of government funding for AMSs being withheld. Staff resourcing, information systems and high-level leadership were perceived to be key drivers of health care quality. On-site specialist services, managed by AMS staff, were considered an enabling strategy to increase specialist access. Candidacy theory suggests the above factors influence whether a service is ‘tractable’ and ‘navigable’ to its users. Staff also described entrenched patient discrimination in hospitals and the need to expend considerable effort to reinstate care. This suggests that Aboriginal and Torres Strait Islander people are still

    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.

    Muir-Torre syndrome is a rare genodermatosis with autosomal dominant inheritance. The syndrome is considered to be a subtype of the hereditary nonpolyposis colorectal cancer (or Lynch-syndrome). In two-third of the cases, it develops as the consequence of germline mutations in mismatch-repair genes--most commonly MutS Homolog-2 and MutL Homolog-1. Its diagnosis can be established if at least one sebaceous tumor (sebaceoma, sebaceous adenoma, epithelioma, carcinoma or basal-cell carcinoma with sebaceous differentiation) and/or keratoacanthoma and at least one internal neoplasm are present. Here the authors present the history of a 52-year-old man with multiple sebaceous carcinomas on his back. Immunohistochemical analysis showed the lack of MutL Homolog-1 protein expression in the tumor cells. Detailed clinical workup in order to identify internal malignancy found malignant coecum tumor. Histopathological evaluation of the sample from the right hemicolectomy revealed mid-grade adenocarcinoma with MutL Homolog-1 and postmeiotic segregation increased-2 deficiency. The detection of the cutaneous sebaceous carcinoma and the application of the modern diagnostic methods resulted in identification of the associated colorectal cancer in an early stage; hence, definitive treatment was available for the patient.

    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

    Rats were exposed to 100% oxygen at 600 torr for up to 8 days. Highly significant increases in RBC anaerobic glycolysis occurred during the first 4 days of exposure and then subsided. Two significant peaks were found, one on days 1 and 2 and one on day 4. The first peak is attributed to reticulocytosis, which was maximal after 90 minutes and had disappeared by day 3. A second mechanism must account for the peak on day 4. An interpretation of the second peak is provided by existing evidence that selective removal of older RBCs occurs during the first few days of exposure to hypobaric oxygen, with maximum effect on day 4. Results in splenectomized, sham-operated and intact animals were indistinguishable from each other. A significant decrease in RBC specific gravity was found in exposed animals with spleens intact, but not in splenectomized animals. Theoretical aspects of age-related parameters as an aid to continuous detection and evaluation of changes in RBC populations are discussed.

    Muir-Torre syndrome is a clinical variant of Lynch syndrome defined by the synchronous or metachronous occurrence of at least one sebaceous neoplasm and at least one Lynch syndrome-related internal cancer. Although screening guidelines for patients with colorectal carcinomas have been established, screening guidelines for cutaneous Muir-Torre associated neoplasms are not currently available. As such, we reviewed the current evidence for the use of MLH1, MSH2, MSH6 and PMS2 immunohistochemistry when cutaneous Muir-Torre associated neoplasms are encountered. We identified weak to moderate support overall for the global use of these assays, with some evidence suggesting a tailored approach using clinical parameters as an adjunct. We also assessed the current utilization patterns of attendees of the American Society of Dermatopathology Annual Meeting (Chicago, 2016). We found that 91% of respondents utilize mismatch repair immunohistochemistry, with the majority utilizing these tests only when requested by the submitting clinician. © 2017 John Wiley & Sons A/S.

    The tumor spectrum in the Lynch syndrome is well defined, comprising an increased risk of developing colonic and extracolonic malignancies. Muir-Torre syndrome is a variant with a higher risk of skin disease. Patients have been described carrying mutations in the mismatch repair genes and presenting tumors with unusual histology or affected organ not part of the Lynch syndrome spectrum. Hence, the real link between Lynch syndrome, or Muir-Torre syndrome, and these tumors remains difficult to assess. We present the case of a 45-year-old-woman, diagnosed with breast cancer at 39 years of age and skin squamous cell carcinoma (SCC) at 41 years of age, without personal history of colorectal cancer. The microsatellite instability analysis performed on the skin SCC showed a low-level of microsatellite instability (MSI-Low). The immunohistochemical expression analysis of the four DNA mismatch repair proteins MLH1, MSH2, MSH6 and PMS2 showed a partial loss of the expression of MSH2 and MSH6 proteins. Germline deletion was found in MSH2 gene (c.1277-? _1661 + ?del), exon 8 to 10. Then, at 45 years of age, she presented hyperplastic polyps of the colon and a sebaceous adenoma. Squamous cell carcinomas have been described in Lynch syndrome and Muir-Torre syndrome in two studies and two case reports. This new case further supports a possible relationship between Lynch syndrome and squamous cell carcinoma.

    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.

    Low uptake of postnatal care among Aboriginal and Torres Strait Islander women is a concern. The aim of this study was to ex-amine any associations with postnatal attendance by Aboriginal and Torres Strait Islander women. A retrospective cohort study was conducted of 198 women who attended Townsville Aboriginal and Islander Health Service (TAIHS) for antenatal care between 1 January 2009 and 1 January 2011. Postnatal attendance and its relationship to demographic, behavioural, antenatal and intrapartum factors was assessed. Of the women included in the study, 48.0% (95/198) returned to TAIHS for postnatal care. A statistically significant positive association between antenatal and postnatal attendance was found using multivariate analysis (P DISCUSSION: Strategies are needed to improve postnatal attendance for Aboriginal and Torres Strait Islander women, and strengthening attendance during the antenatal period may be an indirect way of facilitating this. Better postnatal follow-up will enhance the capacity for health services to deliver preventive care to this population.

    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

    Identifying and targeting those at greatest risk will likely play a significant role in developing the most efficient and cost-effective sexually transmissible infections (STI) prevention programs. We aimed to develop a risk prediction algorithm to identify those who are at increased risk of STI. A cohort (N = 2320) of young sexually active Aboriginal and Torres Strait Islander people (hereafter referred to as Aboriginal people) were included in this study. The primary outcomes were self-reported high-risk sexual behaviors and past STI diagnosis. In developing a risk algorithm, our study population was randomly assigned to either a development (67%) or an internal validation data set (33%). Logistic regression models were used to create a risk prediction algorithm from the development data set for males and females separately. In the risk prediction models, older age, methamphetamine, ecstasy, and cannabis use, and frequent alcohol intake were all consistently associated with high-risk sexual behaviors as well as with a past STI diagnosis; identifying as gay/bisexual was one of the strongest factors among males. Those who had never tested for STIs, 52% (males) and 66% (females), had a risk score >15, and prevalence of undiagnosed STI was estimated between 30 and 40%. Since universal STI screening is not cost-effective, nor practical in many settings, targeted screening strategies remain a crucial and effective approach to managing STIs among young Aboriginal people. Risk prediction tools such as the one developed in this study may help in prioritizing screening for STIs among those most at risk.

    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.

    To explore what role chloroplast positioning might have in relation to latitudinal variation in mesophyll conductance (g m ) of Populus trichocarpa Torr. & Gray (black cottonwood), we examined photosynthetic response to different blue light treatments in six representative genotypes (three northern and three southern). The proportion of blue (B) to red light was varied from 0:100, 10:90, 20:80, 40:60, and 60:40 while keeping the total photosynthetic photon flux density constant. Mesophyll conductance was estimated by monitoring chlorophyll fluorescence in combination with gas exchange. Compared to the control (10% B), g m was significantly lower with increasing blue light. Consistent with a change in chloroplast positioning, there was a simultaneous but reversible decrease in chlorophyll content index (CCI), as measured by foliar greenness, while the extracted, actual chlorophyll content (ACC) remained unchanged. Blue-light-induced decreases in g m and CCI were greater in northern genotypes than in southern genotypes, both absolutely and proportionally, consistent with their inherently higher photosynthetic rate. Treatment of leaves with cytochalasin D, an inhibitor of actin-based chloroplast motility, reduced both CCI and ACC but had no effect on the CCI/ACC ratio and fully blocked any effect of blue light on CCI. Cytochalasin D reduced g m by ∼56% under 10% B, but did not block the effect of 60% B on g m , which was reduced a further 20%. These results suggest that the effect of high blue light on g m is at least partially independent of chloroplast repositioning. High blue light reduced carbonic anhydrase activity by 20% (P<0.05), consistent with a possible reduction in protein-mediated facilitation of CO 2 diffusion. Copyright © 2017 Elsevier GmbH.

    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.

    Chronic diseases disproportionately burden Aboriginal and Torres Strait Islander people in Australia, with cardiovascular (CV) diseases being the greatest contributor. To improve quality of life and life expectancy for people living with CV disease, secondary prevention strategies such as rehabilitation and self-management programs are critical. However, there is no published evidence examining the effect of chronic condition self-management (CCSM) group programs for Aboriginal and Torres Strait Islander people who have, or are at risk of, CV disease specifically. This study evaluates the Work It Out program for its effect on clinical outcome measures in urban Aboriginal and Torres Strait Islander participants with or at risk of CV disease. This study was underpinned by a conceptual framework based on Aboriginal and Torres Strait Islander community control. Participants had at least one diagnosed CV disease, or at least one CV disease risk factor. Short-term changes in clinical outcome measures over (approximately) 12 weeks were evaluated with a quasi-experimental, pre-post test design, using paired t-tests. Factors contributing to positive changes were tested using general linear models. The outcome measures included blood pressure (mmHg), weight (kg), body mass index (kg/m 2 ), waist and hip circumference (cm), waist to hip ratio (waist cm/hip cm) and six minute walk test (6MWT). Changes in several clinical outcome measures were detected, either within the entire group (n = 85) or within specific participant sub-groups. Participant's 6MWT distance improved by an average 0.053 km (95% CI: 0.01-0.07 km). The change in distance travelled was influenced by number of social and emotional wellbeing conditions participants presented with. The weight of participants classified with extreme obesity decreased on average by 1.6 kg (95% CI: 0.1-3.0 kg). Participants with high baseline systolic blood pressure demonstrated a mean decrease of 11 mmHg (95% CI: 3.2-18.8

    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

    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

    Health promotion by and with Aboriginal and Torres Strait Islander (hereafter Indigenous) Australians is critically important given a wide gap in health parity compared to other Australians. The development and implementation of step-by-step guides, instruments, packages, frameworks or resources has provided a feasible and low-resource strategy for strengthening evidence-informed health promotion practice. Yet there has been little assessment of where and how these tools are implemented or their effectiveness. This paper reviews the characteristics, implementation and effects of Indigenous health promotion tools. Indigenous health promotion tools were identified through a systematic literature search including a prior scoping study, eight databases, references of other reviews and the authors' knowledge (n = 1494). Documents in the peer reviewed and grey literature were included if they described or evaluated tools designed, recommended or used for strengthening Indigenous Australian health promotion. Eligible publications were entered into an Excel spreadsheet and documented tools classified according to their characteristics, implementation and effects. Quality was appraised using the Dictionary for Effective Public Health Practice Project (EPHPP) and Critical Appraisal Skills Program (CASP) tools for quantitative and qualitative studies respectively. The review found that Indigenous health promotion tools were widely available. Of 74 publications that met inclusion criteria, sixty (81%) documented tools developed specifically for the Indigenous Australian population. All tools had been developed in reference to evidence; but only 22/74 (30%) publications specified intended or actual implementation, and only 11/74 (15%) publications evaluated impacts of the implemented tools. Impacts included health, environmental, community, organisational and health care improvements. The quality of impact evaluations was strong for only five (7%) studies. The small number and

    Full Text Available BackgroundSocial and emotional wellbeing (SEWB is a critical determinant of health outcomes for Indigenous Australians. This study examined the extent to which primary healthcare services (PHSs undertake SEWB screening and management of Aboriginal and Torres Strait Islander clients, and the variation in SEWB screening and management across Indigenous PHS.MethodsCross-sectional analysis between 2012 and 2014 of 3,407 Indigenous client records from a non-representative sample of 100 PHSs in 4 Australian states/territory was undertaken to examine variation in the documentation of: (1 SEWB screening using identified measurement instruments, (2 concern regarding SEWB, (3 actions in response to concern, and (4 follow up actions. Binary logistic regression was used to determine the factors associated with screening.ResultsThe largest variation in SEWB screening occurred at the state/territory level. The mean rate of screening across the sample was 26.6%, ranging from 13.7 to 37.1%. Variation was also related to PHS characteristics. A mean prevalence of identified SEWB concern was 13% across the sample, ranging from 9 to 45.1%. For the clients where SEWB concern was noted, 25.4% had no referral or PHS action recorded. Subsequent internal PHS follow up after 1 month occurred in 54.7% of cases; and six-monthly follow up of referrals to external services occurred in 50.9% of cases.ConclusionOur findings suggest that the lack of a clear model or set of guidelines on best practice for screening for SEWB in Indigenous health may contribute to the wide variation in SEWB service provision. The results tell a story of missed opportunities: 73.4% of clients were not screened and no further action was taken for 25.4% for whom an SEWB concern was identified. There was no follow up for just under half of those for whom action was taken. There is a need for the development of national best practice guidelines for SEWB screening and management, accompanied by

    Full Text Available The Torres Book from the Sanchez Garza collection is one of the most polemic issues in the study of Hispanic music. This controversy has been the result of two main factors. On the one hand, the authorship problems and on the other, the apparent disorder of the musical content in this manuscript due to the ineffi cient work done by the copiers who gave it form. The latter has lead to conclude, as a generalized opinion, that it is a highly corrupted copy of the organ works that could have been composed by the famous Spanish composer, organist, musical theorist and printer, Joseph de Torres y Martinez Bravo (*1670c; †1738; in which case the copier would be the one to blame for the demerit of such a renowned musician of the Royal Chapel of Madrid. If to this we add the transcription offered by the CENIDIM in 1993 which multiplies the confusion, we are facing pieces of music full of questions and a musical text which is neither effective nor convincing.El Libro de Torres de la colección Sánchez Garza, es uno de los documentos más polémicos de los últimos tiempos en la musicología hispánica.

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.

    Aboriginal and Torres Strait Islander children in Australia experience a higher prevalence of disability and socio-economic disadvantage than other Australian children. Early intervention is vital for improved health outcomes, but complex and fragmented service provision impedes access. There have been international and national policy shifts towards inter-sector collaborative responses to disability, but more needs to be known about how collaboration works in practice. A systematic integrative literature review using a narrative synthesis of peer-reviewed and grey literature was undertaken to describe components of inter- and intra-sector collaborations among services to Aboriginal and Torres Strait Islander children with a disability and their families. The findings were synthesized using the conceptual model of the ecological framework. Thirteen articles published in a peer-reviewed journal and 18 articles from the grey literature met inclusion criteria. Important factors in inter- and intra-sector collaborations identified included: structure of government departments and agencies, and policies at the macro- (government) system level; communication, financial and human resources, and service delivery setting at the exo- (organizational) system level; and relationships and inter- and intra-professional learning at the meso- (provider) system level. The policy shift towards inter-sector collaborative approaches represents an opportunity for the health, education and social service sectors and their providers to work collaboratively in innovative ways to improve service access for Aboriginal and Torres Strait Islander children with a disability and their families. The findings of this review depict a national snapshot of collaboration, but as each community is unique, further research into collaboration within local contexts is required to ensure collaborative solutions to improve service access are responsive to local needs and sustainable.

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

    Since 2006 the Australian Medical Council (AMC) accreditation standards have required medical schools to comprehensively address issues related to the health of Aboriginal and Torres Strait Islander peoples in Australia, and Māori in New Zealand. This has spanned areas of staff expertise, staff and student recruitment, curriculum and institutional leadership. These Indigenous specific standards have, until now, been absent for specialist medical college accreditation. The AMC revised its accreditation standards for specialist medical colleges in 2015, and for the first time included Indigenous specific standards. This commentary presents a guideline to support Australasian medical colleges' responsiveness to these Indigenous specific standards.

    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. Behavioural and psychosocial surveys are administered to assess physical activity, dietary intake and the participant's motivation, self-efficacy and perceived social support for physical activity. Qualitative interviews focusing on participants' motivation, enablers and barriers to healthy eating and physical activity will be undertaken. Implementation fidelity and participation are also assessed. Discussion The Aboriginal and Torres Strait Islander Women's Fitness Program (WFP is designed

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.

    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. 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). 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%; OR(adjusted) = 2.8 (1.6-5.0). 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.

    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.

It contained 19 Roman asses and one semis, and 9 units from Castulo/Ka.?.ti.l.o (Cazlona, Jaén. This coin find contributes to the study of mixed bronze coin hoards –Roman and local coinage– in the south of Hispania during the second half of the second century bc. Its possible formation in the mining district of Castulo, well connected with de port of Malaca by an ancient pre-Roman road known by archaeological and literary sources, are discussed here. Finally, it is emphasized the role of Roman bronzes in relation to the local coinages, especially from 146/141 bc, and also the changes in the metrological criteria during the 1st century bc.

    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 Abstract Background 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. Methods 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. Results 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. Conclusions Aboriginal and Torres Strait Islander

    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 aims of this study were to determine the significance of expression of DNA mismatch repair proteins in detecting systemic malignancies in a series of patients with periocular sebaceous cell carcinoma and to determine the clinical characteristics and frequency of Muir-Torre syndrome in this cohort. The study was a retrospective non-comparative interventional case series. 31 patients with histologically proven sebaceous cell carcinoma of the eyelid participated in the study. The authors made use of retrospective chart review and immunohistochemical staining of specimens. The main outcome measures are as follows: location, tumour size, sites of origin, growth patterns, management, histopathological and immunohistochemical findings, metastasis, other visceral malignancies and mortality. The median age of presentation of the 31 patients in this study was 71 years (range 35-92 years). There was a near-equal gender distribution (M:F-14:17). The average follow-up was 72 months. Seventeen patients had tumours arising from the upper lid, 13 from the lower lid and 1 from the caruncle. Nine patients had clinical Muir-Torre syndrome. Four patients were positive for microsatellite instability complexes and four were negative. Histologically, 14 patients had a high-grade tumour, 13 were intermediate grade and 4 were low grade. Based on the in situ pattern, six patients had a bowenoid pattern, five had both bowenoid and pagetoid patterns and two had a pagetoid pattern. Eighteen patients had no in situ disease detected. Twenty-one patients were alive without disease, and two were alive with disease. Six patients had died, five from other causes and one from the disease. Visceral malignancies are common in patients with periocular sebaceous cell carcinoma. Approximately one in eight demonstrated a heritable risk for further visceral malignancy through failure to express DNA mismatch repair proteins. Diagnosis of periocular sebaceous cell carcinoma should prompt physicians to

    Full Text Available Abstract Background In Australia, rheumatic heart disease (RHD is almost exclusively restricted to Aboriginal Australian and Torres Strait Islander people with children being at highest risk. International criteria for echocardiographic diagnosis of RHD have been developed but the significance of minor heart valve abnormalities which do not reach these criteria remains unclear. The Rheumatic Fever Follow-Up Study (RhFFUS aims to clarify this question in children and adolescents at high risk of RHD. Methods/design RhFFUS is a cohort study of Aboriginal and/or Torres Strait Islander children and adolescents aged 8–17 years residing in 32 remote Australian communities. Cases are people with non-specific heart valve abnormalities detected on prior screening echocardiography. Controls (two per case are age, gender, community and ethnicity-matched to cases and had a prior normal screening echocardiogram. Participants will have echocardiography about 3 years after initial screening echocardiogram and enhanced surveillance for any history suggestive of acute rheumatic fever (ARF. It will then be determined if cases are at higher risk of (1 ARF or (2 developing progressive echocardiography-detected valve changes consistent with RHD. The occurrence and timing of episodes of ARF will be assessed retrospectively for 5 years from the time of the RhFFUS echocardiogram. Episodes of ARF will be identified through regional surveillance and notification databases, carer/subject interviews, primary healthcare history reviews, and hospital separation diagnoses. Progression of valvular abnormalities will be assessed prospectively using transthoracic echocardiography and standardized operating and reporting procedures. Progression of valve lesions will be determined by specialist cardiologist readers who will assess the initial screening and subsequent RhFFUS screening echocardiogram for each participant. The readers will be blinded to the initial assessment and

  9. The role of viscosity in the emplacement of high-temperature acidic flows of Serra Geral Formation in Torres Syncline (Rio Grande do Sul State, Brazil

    Directory of Open Access Journals (Sweden)

    Matheus Silva Simões

    Full Text Available The acidic flows from Serra Geral Formation in Torres Syncline, Rio Grande do Sul, Brazil, are on the top of a volcanic sequence composed by a complex facies association of compound, simple and rubbly pahoehoebasic flows, acidic lava domes, and tabular acidic lava flows. The origin and emplacement conditions of the acidic volcanic rocks are discussed in this paper based on petrology, on calculated apatite saturation thermometry temperatures, and on estimated viscosity data. The liquidus temperatures for metaluminous rhyodacite to rhyolite samples are about 1,067.5 ± 25ºC in average. The viscosity (η values vary from 105 to 106 Pas for anhydrous conditions, suggesting the emplacement of high-temperature - low-viscosity lava flows and domes. The occurrence of acidic lava domes above simple pahoehoe flows as flow-banded vitrophyres was under low effusion rates, in spite of their high temperature and low viscosities, which are reflected in their small height. The emplacement of lava domes has continued until the eruption of rubbly pahoehoe flows and the geometry of these deposits rugged the relief. Presence of tabular acidic lava flows covering the landscape indicates that it was under high effusion rates conditions and such flows had well-insulated cooled surface crusts. The capacity to attain greater distances and overpass relief obstacles is explained not only by high effusion rates, but also by very low viscosities at the time of emplacement.

    The Muir-Torre syndrome (MTS) is a subtype of the Lynch syndrome (hereditary nonpolyposis colorectal cancer). In addition to tumours typically related to LS, MTS is associated with tumours of the sebaceous gland or keratoacanthoma. MTS is mostly characterised by a mutation of MSH2. In contrast to LS-associated tumours carrying a mutation of MLH1, MSH6 or PMS2, the frequency of urological neoplasms seems to be higher in Lynch syndrome patients with MSH2 mutation. Urological implications for the care of patients with LS or MTS include the early diagnosis of a possible hereditary background in patients presenting with urothelial cancers at an atypically young age and potentially the surveillance of carriers of mutations with an increased risk for urothelial cancers like males harbouring a MSH2 mutation. We report on a patient with various types of LS-associated cancers and cancers without a known association with LS, who died from multifocal metastasis of urothelial cancer. This case report shows that close interdisciplinary cooperation is mandatory for the treatment of patients with complex diseases. © Georg Thieme Verlag KG Stuttgart · New York.

    Sebaceous tumours and keratoacanthomas are uncommon neoplasms that constitute important clinical criteria for Muir-Torre syndrome (MTS) diagnosis. In MTS patients, the increased risk of developing synchronous or metachronous visceral malignancies is characterised by autosomal dominant inheritance. However, there are further conditions, other than MTS, that increase the risk of sebaceous neoplasms, e.g. iatrogenic immunosuppression. In this latter scenario, the sebaceous tumours can present microsatellite instability (MSI) and loss of mismatch repair (MMR) proteins, characteristic of hereditary syndromes, even in the absence of MMR germline mutations. In this article, we examine transplant probands in which the immunosuppressive therapies unmask the MTS cutaneous phenotypes, showing MSI and loss of MMR protein expression, as demonstrated by immunohistochemistry (IHC). Furthermore, MMR genes sequencing analysis identified the presence of germline mutations in MTS-suspected individuals, in the absence of a visceral MTS phenotype. It is well known that immunosuppression plays a central role in the development of sebaceous tumours in both MTS and in non-syndromic settings. Sebaceous skin tumours' MSI status and IHC profiles can be influenced by epigenetic or iatrogenic factors; however, they constitute valuable tools and a cost-effective approach to screen individuals who otherways should undergo MMR genes direct sequencing in the context of immunosuppression. In this complex setting, the choice of the immunosuppressive drug becomes a critical decision for the management of both MTS and sporadic transplant patients, which may benefit from the administration of immunosuppressive drugs, resulting in a low impact on skin cancerogenesis.

    Muir-Torre Syndrome (MTS) is a rare hereditary autosomal dominant cancer syndrome and is linked to hereditary non-polyposis colorectal carcinoma (Lynch Syndrome). Individuals develop various skin neoplasms in addition to colorectal, endometrial and upper gastrointestinal malignancies. Therapy-associated myelodysplastic syndrome (T-MDS) is an aggressive hematologic malignancy and is considered a pre-leukemic phase. T-MDS is associated with prior exposure to chemo- and radiotherapy that potentially results in DNA damage. The current case report presents a 74-year-old male MTS patient with prior history of solid tumors and radiation therapy with new onset cytopenia. A subsequent bone marrow biopsy revealed multilineage dysplasia with a high blast count and a diagnosis of high grade T-MDS was rendered. FISH and G-banded karyotype analyses revealed 5q deletion and monosomy 7. This is a unique case of T-MDS arising in the setting of MTS. Secondary malignancies including MDS and acute leukemia may occur in cancer survivors and are often associated with an unfavorable prognosis. This case demonstrates the need to be aware of the risk of secondary hematologic malignancies in cancer patients and a thorough clinical and lab work-up are warranted in patients with persistent or transfusion requiring cytopenia(s).

    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.

Faculdade de Medicina da Universidade do Recife, Tese Livre Docência, p. 56]. In this report, a juvenile ostrich and a house sparrow, both originating from a riverside property in the town of Petrolina in the state of Pernambuco, presented 87 and eight nodules, respectively, on various locations of their bodies. Physical expression of the nodules liberated parasites that were morphologically identified as mites from the family Trombiculidae. The mites were further identified as Apolonia tigipioensis by the presence of an elongated body form and transversely striated, three pairs of long legs each with seven segments, primary coxae with a single seta, each tarsus terminating with three claws, and a scutum with an anteromedian projection and paired anteromedian setae. Histopathologic examination of skin biopsies from these birds, stained with hematoxilin-eosin, revealed acute parasitic cystic lymphoplasmacytic dermatitis.

    General emissions of volatile organic compounds from wood are well investigated, but only limited information is available on the odor-active substances contained therein. To close this gap, we aimed at specifically elucidating the odorous constituents of wood from incense cedar [Calocedrus decurrens (Torr.) Florin]; this material is commonly used for the production of a range of products such as pencils and interior accessories. Targeted odorant analysis requires specialized techniques combining modern odorant analytical tools with human-sensory evaluation. Following this concept, the odor profile of the wood sample was first evaluated by human-sensory analyses. Then, the most potent wood odorants were characterized by means of gas chromatography-olfactometry and ranked according to their odor potency via aroma extract dilution analysis. With use of this approach, more than 60 odorous substances were detected, and the 22 most potent odorants were successfully identified by gas chromatography-mass spectrometry/olfactometry and two-dimensional gas chromatography-mass spectrometry/olfactometry. Among the main odorants found were a series of terpenes, several degradation products of fatty acids, and a number of odorants with a phenolic core moiety. Five odorants are reported here for the first time as wood odorants, such as γ-octalactone and 3-phenylpropanoic acid; thymoquinone was demonstrated for the first time to have a pencil-like odor quality.

    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 (p<0.05). Differences between methods are consistent with differential reporting bias seen in self-reported dietary data. Implications for public health: The NATSINPAS provides valuable, much-needed information about dietary intake; however, self-reported data is prone to energy under-reporting and reporting bias. Purchase data can be used to track population-level food 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.

    Using ambient pressure X-ray photoelectron spectroscopy (APXPS) and high pressure scanning tunneling microscopy (HPSTM), we show that in equilibrium with 0.01-0.2 Torr of methanol vapor, at room temperature, the Cu(100) surface is covered with methoxy species forming a c(2 × 2) overlayer structure. In contrast, no methoxy is formed if the surface is saturated with an ordered oxygen layer, even when the methanol pressure is 0.2 Torr. At oxygen coverages below saturation, methanol dissociates and reacts with the atomic oxygen, producing methoxy and formate on the surface, and formaldehyde that desorbs to the gas phase. Unlike the case of pure carbon monoxide and carbon dioxide, methanol does not induce the restructuring of the Cu(100) surface. These results provide insight into catalytic anhydrous production of aldehydes.

De un lado las políticas económicas y sociales, que salvo excepciones no han hecho sino impulsar la desigualdad, la pobreza y la exclusión social. Del otro la academia, la profesión y las políticas urbanas heredadas del planeamiento urbano moderno, las cuales han probado fomentar la segregación espacial, anular la diversidad y destruir el ámbito público. Pero este complejo de 45 plantas y 110.000 m2 era una entidad híbrida, vertical y vacante en el mismo corazón de la ciudad cuya obsolescencia como objeto físico, político y económico fue objetivo de una presión social ya incontenible. Tanto por su escala y diversidad como por su estado inacabado, sus moradores descubrieron una condición urbana excepcional para reconstruir su nueva identidad como ciudadanos. Un conjunto de cinco sistemas abiertos con los que transformar aquella obsolescencia en una parte de la ciudad alternativa; una infraestructura social. Como ya hicieran otros maestros en el pasado el proceso de Torre David replantea, ahora de forma anónima, bajo qué condiciones los sistemas abiertos permiten elaborar estrategias de regeneración urbana y social, sistemas con los que diluir las complicadas fronteras internas creadas en la ciudad contemporánea.

    Full Text Available Muovendo dal presupposto, teorizzato da Baudouin de Courtenay, secondo il quale il mutamento linguistico è costitutivo del linguaggio umano e pertanto la nozione di monolinguismo andrebbe superata, i dialetti sloveni di area friulana, esposti alla millenaria azione del romanzo, rappresentano un terreno ideale per gli studi sull'interferenza, in quanto rendono perspicui fenomeni da contatto altrimenti difficili da individuare. Il primo ad aver colto una tale opportunità fu lo stesso Baudouin, che visitò ripetutamente le vallate snodantisi lungo (l'attuale confine italo-sloveno, raccogliendovi materiali dialettologici solo in parte pubblicati. Uno dei complessi più notevoli rimasti inediti per oltre un secolo è costituito dal Glossario del dialetto del Torre, le cui schede risalgono agli anni 1873 e 1901. Esso registra un gran numero di prestiti e calchi romanzi, alcuni dei quali risultano del massimo interesse, perché documentano da un lato la forza incisiva di un sistema sull'altro in presenza di condizioni di natura strutturale e storico-culturale particolarmente favorevoli; dall'altro, la capacità di elaborazione originale del modello forestiero ad opera del sistema ricevente. Il contributo si concentra su un fenomeno di calco assai complesso compiuto sul friulano, che investe il sistema dell'imperativo, estraendone in maniera originale un paradigma di congiuntivo, ignoto alla grammatica slovena. Il mutamento viene seguito nelle sue varie fasi, a iniziare dalle motivazioni di ordine generale che ne stanno a monte, per passare a quelle specifiche di natura morfosintattica, connesse con l'interlingua sloveno-friulana.

    Muir-Torre syndrome (MTS) is a rare autosomal dominant genodermatosis caused by mutations in mismatch repair genes. It is characterized by the presence of at least one sebaceous skin tumor associated with internal malignancies. Whether positron emission tomography/computed tomography (PET/CT) is useful for the detection of malignancies in patients with MTS has not been determined. We herein report two cases in which PET/CT was useful for the diagnosis and follow-up of internal malignancies in patients with MTS. In case 1, a 57-year-old woman underwent excision of a sebaceous carcinoma on the left upper eyelid. She underwent follow-up PET/CT once yearly thereafter. Forty-two months after the eyelid surgery, PET/CT showed intense tracer uptake in the right lower abdomen. An ascending colon tumor was identified, and examination of a biopsy specimen showed adenocarcinoma. In case 2, a 77-year-old man presented for evaluation of three continuous papules with telangiectasia on his right cheek. Examination of a skin biopsy specimen of the cheek papule revealed a sebaceous carcinoma. He underwent PET/CT to detect other malignancies. PET/CT showed intense tracer uptake in the sigmoid colon. A sigmoid colon tumor was identified, and examination of a biopsy specimen showed adenocarcinoma. Both patients underwent resection of their tumors, and both were still free of recurrence of the sebaceous and colon carcinomas at the time of this writing. PET/CT is a reliable imaging modality for the detection of internal malignancies and is useful for the diagnosis and follow-up of MTS.

    Muir-Torre syndrome, a Lynch syndrome variant, is characterized by sebaceous neoplasia plus one or more malignancies, typically colon cancer. The significance of DNA mismatch repair (MMR) deficiency detection by immunohistochemistry (IHC) in colorectal carcinomas is well established and is recommended as a screening tool for Lynch syndrome in newly diagnosed colorectal carcinomas. In comparison, literature on IHC application to detect MMR proteins (MLH1, MSH2, MSH6, and PMS2) in sebaceous neoplasia has been less studied and has been derived almost exclusively from tertiary care centers. Herein we describe the largest series to date characterizing MMR deficiency in sebaceous neoplasms, as well as the relative frequencies of each deficiency. Two hundred sixteen consecutive sebaceous neoplasms (216 patients) were analyzed from a community practice setting (133 sebaceous adenomas, 68 sebaceomas, 15 sebaceous carcinomas). One hundred forty-three were MMR deficient (66%), of which 90 were MSH2/MSH6 deficient (63%), 27 MLH1/PMS2 deficient (19%), 22 MSH6 deficient (15%), and 4 PMS2 deficient (3%). MMR deficiency was significantly associated with site, with tumors off of the head and neck more likely to be MMR deficient (specificity 96%). In contrast to prior reports, no significant trend in MMR-deficient versus -nondeficient tumors was seen in age at presentation (median age, 68 versus 66), tumor-infiltrating lymphocytes, or tumor type. Given the low sensitivity of age < 60 years (30%), location off of the head and neck (41%), or presence of tumor-infiltrating lymphocytes (29%) in MMR deficiency detection, IHC screening programs should test all sebaceous neoplasms for MMR deficiency, regardless of their clinicopathological features.

    The Muir-Torre syndrome (MTS), a variant of Lynch syndrome (LS), is characterized by the presence of sebaceous skin adenomas and/or carcinomas and keratoacanthomas associated with visceral malignancies. Fordyce granules (FGs) are oral mucosal lesions previously found in association with LS. The aim of this study was to analyze the specific frequency of FGs in sporadic individuals and gene carriers patients with MTS of known mismatch repair genes mutations. The secondary aim was to characterize FGs by means of reflectance confocal microscopy (RCM). A total of 13 patients belonging to nine different genetically unrelated MTS kindreds (MLH1 gene mutation n = 2; MSH2 gene mutation n = 11) and 140 genetically unrelated healthy controls were examined. Depending on the clinical examination of the oral mucosa surface, subjects were categorized as either FGs positive or FGs negative. FGs were diagnosed in 13 of 13 (100%) of MMR gene carriers patients with MTS vs. 9 of 140 (6.4%) controls. The most common site for FGs in MTS was the vestibular oral mucosa, compared with the gingival mandibular and retromandibular pad in controls. RCM examination found multiple sebaceous acinar cells that appear as round or oval hyper-refractive globules and that create a lobular aspects of the sebaceous glands defined as 'moruliform' or 'berry-like' structures. Clinical and RCM evidences of our study suggest that an activation of the sebaceous glands system occurs in patients with MTS. Fordyce granules and intra-oral sebaceous hyperplasia may constitute an additional clinical parameter, which may be adopted to distinguish individuals with highest likelihood of being affected from MTS. © 2014 John Wiley & Sons A/S.

    There is now considerable evidence that racism is a pernicious and enduring social problem with a wide range of detrimental outcomes for individuals, communities and societies. Although indigenous people worldwide are subjected to high levels of racism, there is a paucity of population-based, quantitative data about the factors associated with their reporting of racial discrimination, about the settings in which such discrimination takes place, and about the frequency with which it is experienced. Such information is essential in efforts to reduce both exposure to racism among indigenous people and the harms associated with such exposure. Weighted data on self-reported racial discrimination from over 7,000 Indigenous Australian adults participating in the 2008-09 National Aboriginal and Torres Strait Islander Survey, a nationally representative survey conducted by the Australian Bureau of Statistics, were analysed by socioeconomic, demographic and cultural factors. More than one in four respondents (27%) reported experiencing racial discrimination in the past year. Racial discrimination was most commonly reported in public (41% of those reporting any racial discrimination), legal (40%) and work (30%) settings. Among those reporting any racial discrimination, about 40% experienced this discrimination most or all of the time (as opposed to a little or some of the time) in at least one setting. Reporting of racial discrimination peaked in the 35-44 year age group and then declined. Higher reporting of racial discrimination was associated with removal from family, low trust, unemployment, having a university degree, and indicators of cultural identity and participation. Lower reporting of racial discrimination was associated with home ownership, remote residence and having relatively few Indigenous friends. These data indicate that racial discrimination is commonly experienced across a wide variety of settings, with public, legal and work settings identified as

  13. Direct effects of soil amendments on field emergence and growth of the invasive annual grass Bromus tectorum L. and the native perennial grass Hilaria jamesii (Torr.) Benth

    Bromus tectorum L. is a non-native, annual grass that has invaded western North America. In SE Utah, B. tectorum generally occurs in grasslands dominated by the native perennial grass, Hilaria jamesii (Torr.) Benth. and rarely where the natives Stipa hymenoides Roem. and Schult. and S. comata Trin. & Rupr. are dominant. This patchy invasion is likely due to differences in soil chemistry. Previous laboratory experiments investigated using soil amendments that would allow B. tectorum to germinate but would reduce B. tectorum emergence without affecting H. jamesii. For this study we selected the most successful treatments (CaCl2, MgCl2, NaCl and zeolite) from a previous laboratory study and applied them in the field in two different years at B. tectorum-dominated field sites. All amendments except the lowest level of CaCl2 and zeolite negatively affected B. tectorum emergence and/or biomass. No amendments negatively affected the biomass of H. jamesii but NaCl reduced emergence. Amendment effectiveness depended on year of application and the length of time since application. The medium concentration of zeolite had the strongest negative effect on B. tectorum with little effect on H. jamesii. We conducted a laboratory experiment to determine why zeolite was effective and found it released large amounts of Na+, adsorbed Ca2+, and increased Zn2+, Fe2+, Mn2+, Cu2+, exchangeable Mg2+, exchangeable K, and NH 4+ in the soil. Our results suggest several possible amendments to control B. tectorum. However, variability in effectiveness due to abiotic factors such as precipitation and soil type must be accounted for when establishing management plans. ?? Springer 2006.

    Disease transmission parameters are the core of epidemic models, but are difficult to estimate, especially in the absence of outbreak data. Investigation of the roaming behaviour, home range (HR) and utilization distribution (UD) can provide the foundation for such parameter estimation in free-ranging animals. The objectives of this study were to estimate HR and UD of 69 domestic dogs in six Aboriginal and Torres Strait Islander communities in northern Australia and to compare four different methods (the minimum convex polygon, MCP; the location-based kernel density estimation, LKDE; the biased random bridge, BRB; and Time Local Convex Hull, T-LoCoH) for investigation of UD and estimating HR sizes. Global positioning system (GPS) collars were attached to community dogs for a period of 1-3 days and positions (fixes) were recorded every minute. Median core HRs (50% isopleth) of the 69 dogs were estimated to range from 0.2 to 0.4 ha and the more extended HR (95% isopleth) to range from 2.5 to 5.3 ha, depending on the method used. The HR and UD shapes were found to be generally circular around the dog owner's house. However, some individuals were found to roam much more with a HR size of 40-104 ha and cover large areas of their community or occasionally beyond. These far roaming dogs are of particular interest for infectious disease transmission. Occasionally, dogs were taken between communities and out of communities for hunting, which enables the contact of dogs between communities and with wildlife (such as dingoes). The BRB and T-LoCoH are the only two methods applied here which integrate the consecutiveness of GPS locations into the analysis, a substantial advantage. The recently developed BRB method produced significantly larger HR estimates than the other two methods; however, the variability of HR sizes was lower compared to the other methods. Advantages of the BRB method include a more realistic analytical approach (kernel density estimation based on movements

    The Miocene Torres del Paine intrusive complex (TPIC) in Patagonia is a transitional alkaline backarc intrusion1 emplaced on short timescales of 162 ± 11 ka2. It is subdivided into two units with distinct ages of ~12.6 Ma and ~12.45 Ma1. Smaller intrusive bodies in the area record a change in chemistry from calc-alkaline at ~16 Ma, to transitional alkaline at ~12.5 Ma. 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

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.

    There are many reported experiments and theoretical calculations for the combination of methyl free radicals diluted in a non-reactive 'deactivator. At high pressure the ethane (C2H6) combination product is the sole product; with decreasing pressure the chemically activated C2H6 will decompose. The falloff in the observed rate coefficient is the result of the competition between collisional stabilization of the chemically activated CA and unimolecular decomposition. The dependence of the rate coefficient on pressure, temperature and collision properties is complex and can not be calculated from first principles. The understanding of this system is not only of fundamental importance but is relevant to the recent detection of methyl free radicals in the atmospheres of Saturn - and Neptune. The temperatures of these outer planet atmospheres are in the 140-200 K region with total pressures (predominately H2 and He) less than 0.2 Torr. Experimentally determined rate coefficients have been reported for this reaction at T = 296-906 K and T = 200-408 K mostly with argon as the deactivator. At T = 200 K only the high pressure rate coefficient has been determined. Complete falloff curves over a wide temperature range (200-1600 K) with a variety of weak collider models used to simulate argon as the deactivator have also been reported by Klippenstein and Harding (KH). More recently we have reported the experimental rate coefficients in the falloff region with helium as the deactivator at 200 and 298 K. In this paper we have used the calculated falloff curves reported by KH for argon to determine the average energy transferred per collision for helium in our recently reported experiments. Collision rates were converted using Lennard Jones parameters; the temperature dependence of this conversion factor is noted. The helium experiments were consistent with a down of approximately 100 cm (exp-1); the temperature dependence was slight. The magnitude of down and its temperature

    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.

    El principio de funcionamiento de torres de refrigeración y condensadores evaporativos se basa en el intercambio de energía y masa entre una corriente de agua y una de aire. Estos dispositivos pulverizan agua que se encuentra con una corriente de aire, y que al no estar saturado, hace que se evapore una pequeña parte de ésta y se enfríe el resto. A su vez, la corriente de aire captura pequeñas gotas de agua, que no han sufrido cambio de fase, y salen al exterior del equipo. A esta cantidad de...

    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

En este trabajo se ha estudiado la aplicación de imágenes de los sensores Landsat ETM+ y ASTER para evaluar la vegetación previa, la superficie recorrida por el fuego y los daños producidos por el incendio ocurrido en el año 2005 en el Parque Nacional de Torres del Paine (Chile. Los resultados obtenidos indican que el índice delta NBR es bastante versátil para evaluar la superficie afectada, estimada en este caso en 17.138 ha, así como la severidad de los daños (Fiabilidad = 81,5 %; k = 0,73. Por otro lado, se ha confirmado la adecuación del uso de imágenes Landsat ETM+ para mejorar la calidad de los mapas de vegetación previa a la ocurrencia del fuego (Fiabilidad = 79,5 %; k = 0,75. La combinación de esta información se ha podido aplicar para apoyar la restauración del área afectada por el incendio. Sin embargo, los resultados también han mostrado algunas limitaciones de los sensores, en particular en la definición de ecosistemas con representaciones superficiales pequeñas y/o fragmentadas, lo cual sugiere que el uso de sensores de mayor resolución espacial puede mejorar los productos cartográficos finales y, por tanto, la calidad de los trabajos de restauraciónThe use of remote sensors is one of the most important aspects in the study of large fires for an assessment of their severity, as well as the application of the results to the restoration process.

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

    Full Text Available Quest’articolo parte dallo studio delle città portuali storiche, siti UNESCO, che oggi affrontano la sfida della riqualificazione dei waterfront urbani attraverso la conservazione del patrimonio culturale e paesaggistico. 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. Il caso Torre Annunziata”, offre la possibilità di superare la sola valutazione degli impatti culturali proposta dall’ICOMOS.

    Full Text Available The child protection system in Australia includes out-of-home care (OoHC for children and young people at risk of harm and neglect. 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

Foi nesse contexto que a Casa da Torre formou seu patrimônio, entre os séculos XVI e XVII. Mais tarde, entretanto, essa medida resultou em um grande entrave para a Coroa, que desembocou em conflitos por posses de terra durante o século XVIII. De um lado, observa-se a Coroa tentando legalizar o sistema sesmarial, por meio da expedição de várias ordens complementares. Do outro lado, observam-se os membros da Casa da Torre, entendendo-se como possuidores da terra de forma inquestionável, e os compradores das terras vendidas pela Casa da Torre, percebendo-se como verdadeiros proprietários da sesmaria.

    Of the estimated 10-11 year life expectancy gap between Indigenous (Aboriginal and Torres Strait Islander people) and non-Indigenous Australians, approximately one quarter is attributable to cardiovascular disease (CVD). Risk prediction of CVD is imperfect, but particularly limited for Indigenous Australians. The BIRCH (Better Indigenous Risk stratification for Cardiac Health) project aims to identify and assess existing and novel markers of early disease and risk in Indigenous Australians to optimise health outcomes in this disadvantaged population. It further aims to determine whether these markers are relevant in non-Indigenous Australians. BIRCH is a cross-sectional and prospective cohort study of Indigenous and non-Indigenous Australian adults (≥ 18 years) living in remote, regional and urban locations. Participants will be assessed for CVD risk factors, left ventricular mass and strain via echocardiography, sleep disordered breathing and quality via home-based polysomnography or actigraphy respectively, and plasma lipidomic profiles via mass spectrometry. Outcome data will comprise CVD events and death over a period of five years. Results of BIRCH may increase understanding regarding the factors underlying the increased burden of CVD in Indigenous Australians in this setting. Further, it may identify novel markers of early disease and risk to inform the development of more accurate prediction equations. Better identification of at-risk individuals will promote more effective primary and secondary preventive initiatives to reduce Indigenous Australian health disadvantage.

    The ectoparasitic harpacticoid copepod, Balaenophilus manatorum (Ortíz, Lalana and Torres, 1992) (syn. Balaenophilus umigamecolus Ogawa, Matsuzaki and Misaki, 1997), has been reported on 3 species of marine turtles from the Pacific and the Mediterranean and from the West Indian manatee off Cuba in the Caribbean. The 3 available descriptions of this species were made using light microscopy. In this paper, we provide an amended description of B. manatorum using scanning electronic microscopy (SEM) for specimens in the collection from which B. umigamecolus was originally described. This material was collected from 1 loggerhead sea turtle, Caretta caretta, from Japan. The use of SEM allowed us to add several new microcharacters to the original description but, more importantly, allowed us to correct a number of the traits originally described. Some of the corrections could affect the interpretation of putative homology and variability of characters among populations of B. manatorum. A SEM comparison of specimens of B. manatorum from loggerheads from Japan and the western Mediterranean suggested the existence of morphological stasis between these populations. However, there were apparent meristic differences with a recently published description of this species from olive ridleys, Lepidochelys olivacea, in Mexico. Although B. manatorum is currently considered as a single, widespread taxon, the possibility that it actually represents a species complex deserves further attention.

    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. 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. 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 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 Australia requires consideration of the underlying social determinants of health.

    Full Text Available Resumo: O presente estudo objetiva avaliar a vulnerabilidade ambiental e social e identificar trechos críticos, na ocorrência de acidentes com o transporte de produtos perigosos na BR-101, entre os municípios de Osório e Torres, Rio Grande do Sul, Brasil. A abordagem proposta e aplicada neste trabalho consiste de uma análise multicriterial que integra metodologias de análise de segurança viária, análise de vulnerabilidade ambiental e social na ocorrência de acidentes com produtos perigosos, e técnicas de análise de mapas. Os resultados apontaram que 38 quilômetros da rodovia apresentam vulnerabilidade elevada, sendo 8 quilômetros com vulnerabilidade crítica, vinculada à presença de pontes sobre rios, pontos de captação de água, túnel, áreas de preservação ambiental e zona urbana. Esses trechos devem ser priorizados no desenvolvimento de planos de ação para a mitigação de acidentes e definição de políticas públicas na rodovia em estudo. A abordagem utilizada constitui um enfoque inédito em relação aos estudos existentes e uma ferramenta que pode auxiliar no processo de tomada de decisões em operações de emergência.

    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. 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 approvals have been granted for the study. Interpretation and dissemination are guided by the study team's Aboriginal leadership and reference groups. Dissemination

    Aboriginal and Torres Strait Islander people (referred to in this paper as "Aboriginal people") generally have lower cancer survivals and more advanced stages at diagnosis than non-Aboriginal people. There is conflicting evidence on whether these disparities vary by socio-economic disadvantage and geographic remoteness. This study examines variations in these disparities in New South Wales (NSW), Australia. Data for cancers diagnosed in 2000-2008 were extracted from the NSW Cancer Registry (n=264,219). Missing Aboriginal status (13.3%) was multiply imputed. Logistic regression and competing risk regression models were used to examine likelihood of advanced summary stage and risk of cancer death among Aboriginal compared with non-Aboriginal people by socio-economic disadvantage (categorised into quintiles 1: least disadvantaged-5: most disadvantaged) and remoteness. Aboriginal people showed a general pattern of more advanced stage at diagnosis compared with non-Aboriginal people across socio-economic disadvantage and remoteness categories. After adjusting for demographic factors, year of diagnosis, summary stage and cancer site, Aboriginal people living outside the least disadvantaged areas had an increased risk of cancer death compared with non-Aboriginal people living in similar areas (sub-hazard ratio SHR 1.41, 95% confidence interval CI 1.09-1.81; SHR 1.59, 95%CI 1.31-1.93; SHR 1.42, 95%CI 1.22-1.64 and SHR 1.34, 95%CI 1.22-1.48 for quintiles 2-5, respectively). Compared with non-Aboriginal people, Aboriginal people had an elevation in the risk of cancer death irrespective of the remoteness, with the most pronounced elevations detected in remote/very remote areas (SHR 1.56, 95%CI 1.10-2.21). Compared with non-Aboriginal people, Aboriginal people had a higher risk of cancer death and higher likelihood of more advanced stage across socio-economic disadvantage and remoteness categories. All areas appear to require attention in endeavours to improve cancer survival

    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

    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)).

The demersal fish families distribution is presented according to its frequencies of occurrence and its particular abundance. As Sciaenidae family shows to be the most important predominant group each species is studied in detail with reference to its distribution and relative abundance, as well as its spatial and temporal variations according to the abiotic environment. Relationship between Sciaenidae species is also discussed concerning feeding habits and the Cole coefficient of inter-specific association is estimated for pairs of species.

    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

    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.

    We report the draft genome of the black cottonwood tree, Populus trichocarpa. Integration of shotgun sequence assembly with genetic mapping enabled chromosome-scale reconstruction of the genome. Over 45,000 putative protein-coding genes were identified. Analysis of the assembled genome revealed a whole-genome duplication event, with approximately 8,000 pairs of duplicated genes from that event surviving in the Populus genome. A second, older duplication event is indistinguishably coincident with the divergence of the Populus and Arabidopsis lineages. Nucleotide substitution, tandem gene duplication and gross chromosomal rearrangement appear to proceed substantially slower in Populus relative to Arabidopsis. Populus has more protein-coding genes than Arabidopsis, ranging on average between 1.4-1.6 putative Populus homologs for each Arabidopsis gene. However, the relative frequency of protein domains in the two genomes is similar. Overrepresented exceptions in Populus include genes associated with disease resistance, meristem development, metabolite transport and lignocellulosic wall biosynthesis.

    The equilibrium constants for the Z to E isomerizations of CF3CF═CHF (K1) and CF3CH═CHCF3 (K2) have been measured using GC/FID analysis over the temperature ranges 360–850 and 297–850 K, respectively. At lower temperature, K was determined using Cl atom catalysis. At higher temperature, K was measured without a catalyst. The temperature-dependent expressions are K1 (Z to E) = 1.45(±0.15)e(–[2845(±100)/RT]) and K2 (Z to E) = 1.9(±0.22)e(+[4330(±120)/RT]) (where the gas constant R ≡ 1.986 cal mol(–1) K(–1)). For isomerization 1, the Z (fluorine cis) isomer is 2.85 kcal mol(–1) lower in energy than the E (fluorine trans) isomer, providing another example of the fluorine "cis effect" in olefins. For isomerization 2, the E(trans) isomer is 4.3 kcal mol(–1) lower in energy than the corresponding Z(cis) isomer as is normal for olefins. The isomerization rate constant in a single direction was also measured for each fluorinated compound: k–1(E to Z) = 10(13.87±0.24)e(–59530(±887)/RT) s(–1); and k2(Z to E) = 10(13.89±0.23)e(–58845(±675)/RT) s(–1). To verify the experimental method, cis to trans (k3) and trans to cis (k–3) isomerization rate constants were also measured for cis- and trans-2-butene for comparison to several previous studies. The rate constants determined herein are k3 (cis to trans) = 10(13.95±0.23)e(–63245(±815)/RT) s(–1); and k–3 (trans to cis) = 10(14.32±0.28)e(–64993(±1132)/RT) s(–1). k3 agrees well with four previous measurements and represents the best available rate constant for 2-butene. All errors quoted here are 2σ. The typical total pressure for these experiments was 760 ± 100 Torr. Limited experiments performed at 100 Torr showed no pressure dependence for any of the compounds above 100 Torr. Thus, all isomerization rate constants represent high-pressure limits. The rates of the addition reactions of Cl to the double bonds of CF3CF═CHF (k4) and CF3CH═CHCF3 (k7) (used in Cl catalysis) were

    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.

    Like other colonised populations, Indigenous Australians experience poorer health outcomes than non-Indigenous Australians. Preventable chronic disease is the largest contributor to the health differential between Indigenous and non-Indigenous Australians, but recommended best-practice preventive care is not consistently provided to Indigenous Australians. Significant improvement in health care delivery could be achieved through identifying and minimising evidence-practice gaps. Our objective was to use clinical audit data to create a framework of the priority evidence-practice gaps, strategies to address them, and drivers to support these strategies in the delivery of recommended preventive care. De-identified preventive health clinical audit data from 137 primary health care (PHC) centres in five jurisdictions were analysed (n = 17,108 audited records of well adults with no documented major chronic disease; 367 system assessments; 2005-2014), together with stakeholder survey data relating to interpretation of these data, using a mixed-methods approach (n = 152 responses collated in 2015-16). Stakeholders surveyed included clinicians, managers, policy officers, continuous quality improvement (CQI) facilitators and academics. Priority evidence-practice gaps and associated barriers, enablers and strategies to address the gaps were identified and reported back through two-stages of consultation. Further analysis and interpretation of these data were used to develop a framework of strategies and drivers for health service improvement. Stakeholder identified priorities were: following-up abnormal test results; completing cardiovascular risk assessments; timely recording of results; recording enquiries about living conditions, family relationships and substance use; providing support for clients identified with emotional wellbeing risk; enhancing systems to enable team function and continuity of care. Drivers identified for improving care in these areas included: strong Indigenous participation in the PHC service; appropriate team structure and function to support preventive care; meaningful use of data to support quality of care and CQI; and corporate support functions and structures. The framework should be useful for guiding development and implementation of barrier-driven, tailored interventions for primary health care service delivery and policy contexts, and for guiding further research. While specific strategies to improve the quality of preventive care need to be tailored to local context, these findings reinforce the requirement for multi-level action across the system. The framework and findings may be useful for similar purposes in other parts of the world, with appropriate attention to context in different locations.

    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.

  8. The Parchment of the "Torre Turpiana ": the original document and its early interpreters

    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 article describes the structural aspects and discusses the loading conditions and calculation procedures of this outstanding building, for which both the vertical and horizontal systems of forces were taken into account. The vertical structure involves 46 load bearing surfaces, of various shapes and of 15 to 20 cm thickness, with folded edges. Thanks to this, among other advantages, it is possible to reduce horizontal tensile forces and increase the strength in buckling. Horizontally, the structure consists of constant thickness slabs, of 20 cm depth, with chapitel reinforcements in the terraced zones. These slabs have constant bending strength in all directions. A separate description is given of the basic structure of the top social zone and of the lower one, related to the parking spaces, the pergola and the foundations.En el artículo se describen los problemas estructurales de un edificio de viviendas, en general, analizando las condiciones de trabajo y el proceso de cálculo de esta estructura singular, para lo que se estudia separadamente la organización vertical y la horizontal. La primera está constituida por 46 pantallas resistentes —de formas diversas y espesores entre 15 y 30 cm— con plegamientos en los bordes, gracias a los cuales se logra, entre otras ventajas, reducir las tracciones horizontales y aumentar el coeficiente de seguridad al pandeo. La organización horizontal adoptada ha sido la de losas de espesores constantes —de 20 cm, con refuerzos de capiteles en las glandes zonas de terrazas— que valoran por igual cualquier dirección de flexión. Se detallan, por separado, las estructuras fundamental, del núcleo social superior, y de la zona inferior, donde existen cuatro partes importantes: muros, aparcamiento, pérgola y cimentación.

    Full Text Available The goal of this project was to design a removable and reusable structure (derrick built with pultrusion profiles of GFRP (Glass Fiber Reinforced Polymers. These profiles have better physical and mechanical properties than those commonly used for these structures, such as steel or concrete profiles. A methodology for drilling an oil field is described in this document. The structure has been worked out by computer program. An economical study with a comparison between the structure designed with common materials and with composites is included. An application to different situations where steel design could not be possible is also shown.El proyecto presenta el diseño de una estructura desmontable y reutilizable para la realización de sondeos de petróleo .La estructura ha sido proyectada con perfiles pultrusionados de material compuesto avanzado ya que presentan unas cualidades, tanto físicas como mecánicas, superiores a la de los materiales convencionales. El empleo de estos materiales ha sido justificado desde el punto de vista técnico y económico. A lo largo del artículo se describen las operaciones requeridas en la explotación por sondeos, así como el planteamiento seguido en el cálculo estructural mediante un programa que tiene por objeto el análisis matricial de estructuras de barras. Al final del mismo se hacen una serie de reflexiones sobre las tendencias futuras de estos materiales.

    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)

    Full Text Available Abstract Background To evaluate immunisation coverage, timeliness and predictors of delayed receipt in urban Australian Indigenous children during the first 18 months of life. Methods Cross-sectional retrospective analysis of data collected from 140 Australian Indigenous children aged < 5 years at the time of enrolment in a prospective cohort study on respiratory illness between 14 February 2013 and 28 January 2015. Children were recruited through an urban community primary health care centre in the Northern suburbs of Brisbane, Queensland. Results The proportion of children with completed immunisation schedules was 50 of 105 (47.6% at 7 months, 30 of 85 (35.3% at 13 months and 12 of 65 (18.5% at 19 months. Timely receipt of diphtheria-tetanus-pertussis decreased from 78.4% at 2 months of age to 63.7 and 59.3% at 4 and 6 months respectively. Amongst the 105 parents/guardians with children ≥7 months at enrolment, 71 (67.6% incorrectly reported their child’s immunisation status. Delayed vaccine receipt was significantly associated (p ≤0.05 with having multiple children in the household, mother’s unemployment and premature birth. Conclusions Coverage and timeliness among this population is suboptimal and decreases as children age. Parent/guardian reporting of vaccination status was unreliable. Children of unemployed mothers and those with multiple siblings should be targeted to improve community immunisation timeliness due to a greater risk of vaccination delay. High quality trials, conducted in several settings to account for the diversity of Australian Indigenous communities are urgently needed to identify culturally appropriate, effective and sustainable strategies to improve immunisation targets in children.

    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 examine associations between fall risk factors identified previously in other populations and falls among Aboriginal people aged 60 years and older, living in New South Wales, Australia. Interviews were conducted with older Aboriginal people in five urban and regional communities. Associations between past falls and 22 fall predictor variables were examined using linear and multiple regression analyses. Of the 336 participants, 80 people (24%) reported at least one fall in the past year, and 34 (10%) reported two or more falls. Participants had an increased fall risk if they were female; used three or more medications; had arthritis, macular degeneration, depression, history of stroke; were unable to do their own housework; or were unable to do their own shopping. Falls were experienced by one-quarter of study participants. Fall risk factors identified for older Aboriginal people appear to be similar to those identified in the general population. Understanding of fall risk factors may assist with the development of appropriate and effective community-led fall prevention programs. © 2017 AJA Inc.

    Social isolation provides a useful tool to study nestmate recognition in ants. In Camponotus fellah, reintroduction of 10-day isolated (IS) workers to their colony resulted in intensive trophallaxis and grooming, while longer isolation periods generally provoked rejection of the IS ants. In the first experiment the behaviour of queenless (QL) and queenright (QR) workers towards 10-day IS workers was tested. Trophallaxis of QL or QR with IS workers was of similar magnitude, but was significant...

    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

    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.

  8. A vacuum (10(exp -9) Torr) friction apparatus for determining friction and endurance life of MoSx films

    The first part of this paper describes an ultrahigh vacuum friction apparatus (tribometer). The tribometer can be used in a ball-on-disk configuration and is specifically designed to measure the friction and endurance life of solid lubricating films such as MoS(x) in vacuum at a pressure of 10 exp -7 Pa. The sliding mode is typically unidirectional at a constant rotating speed. The second part of this paper presents some representative friction and endurance life data for magnetron sputtered MoS(x) films (110 nm thick) deposited on sputter-cleaned 440 C stainless-steel disk substrates, which were slid against a 6-mm-diameter 440 C stainless-steel bearing ball. All experiments were conducted with loads of 0.49 to 3.6 N (average Hertzian contact pressure, 0.33 to 0.69 GPa), at a constant rotating speed of 120 rpm (sliding velocity ranging from 31 to 107 mm/s due to the range of wear track radii involved in the experiments), in a vacuum of 7 x 10 exp -7 Pa and at room temperature. The results indicate that there are similarities in friction behavior of MoS(x) films overs their life cycles regardless of load applied. The coefficient of friction (mu) decreases as load W increases according to mu = kW exp -1/3. The endurance life E of MoS(x) films decreases as the load W increases according to E = KW exp -1.4 for the load range. The load- (or contract-pressure-) dependent endurance life allows us to reduce the time for wear experiments and to accelerate endurance life testing of MoS(x) films. For the magnetron-sputtered MoS(x) films deposited on 440 C stainless-steel disks: the specific wear rate normalized to the load and the number of revolutions was 3 x 10 exp -8 mm exp 3/N-revolution; the specific wear rate normalized to the load and the total sliding distance was 8 x 10 exp -7 mm exp 3/N-m; and the nondimensional wear coefficient of was approximately 5 x 10 exp -6. The values are almost independent of load in the range 0.49 to 3.6 N (average Hertzian contact pressures of 0.33 to 0.69 GPa).

    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.

  17. A separação dos torrões de terra roxa do café, pelo magnetismo

    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.

  18. Shape of argon spectral lines emitted from an electric arc (P=760 Torr). Study and application of pressure broadening

    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

  1. 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.

    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.

  14. Aspects of the biology of Salicornia bigelovii torr. In relation to a proposed restoration of a wind-tidal flat system on the South Texas, USA Coast

    Science.gov (United States)

    Onuf, C.P.

    2006-01-01

    Wind-tidal flats are the dominant coastal wetland type in southern Texas USA. Succulent vascular plants are colonizing the flats in some locations, often where past dredge disposal along navigation channels and other activities have interrupted natural water communication between hypersaline bays and large areas of wind-tidal flats. The objective of this study was to test the feasibility of proposed removal of a causeway at Laguna Atascosa National Wildlife Refuge to restore the historic hydrologic regime and eradicate encroaching vascular plants, mostly Salicornia bigelovii, on the assumption that high sediment salt excluded these vascular plants under natural conditions. Assessment in spring 1998 of the density of Salicornia in relation to elevation and sediment salt of bare and vegetated zones on the vegetated flats on one side of the causeway and entirely barren flats with unimpaired connection to Laguna Madre on the other side of the causeway suggested that sediment salt >0.1 g ml-1 excluded vascular plants. However, bimonthly sampling in 1999-2000 revealed that sediment salt concentrations were >0.1 g ml-1 throughout the vegetated zone in July and more locally in the period of winter low water, with little impairment to established plants. This indicates that if control is desired, it must be exerted at germination and early establishment during and after fall high water. Continuous monitoring of water levels on either side of the causeway suggests that, even with removal of the causeway, flooding with hypersaline lagoon water will be too infrequent to counteract the freshening effect of a permanent hydraulic connection to the main agricultural drain of the lower Rio Grande Valley that has developed at the other end of the salt flat. Monitoring Salicornia distribution over six years documented huge variation between years but no trend toward increasing dominance of the flats. The results of this study illustrate that the most obvious alterations to a site may not be the most influential on function and that the scale of analysis may have to extend far beyond the site in space and time to evaluate a proposed restoration properly. ?? 2006, The Society of Wetland Scientists.

    Aboriginal Australians are a culturally, linguistically and experientially diverse population, for whom national statistics may mask important geographic differences in their health and the determinants of their health. We sought to identify the determinants of health of Aboriginal adults who lived in the state of Victoria, compared with their non-Aboriginal counterparts. We obtained data from the 2008 Victorian Population Health Survey: a cross-sectional computer-assisted telephone interview survey of 34,168 randomly selected adults. The data included measures of the social determinants of health (socioeconomic status (SES), psychosocial risk factors, and social capital), lifestyle risk factors, health care service use, and health outcomes. We calculated prevalence ratios (PR) using a generalised linear model with a log link function and binomial distribution; adjusted for age and sex. Aboriginal Victorians had a higher prevalence of self-rated fair or poor health, cancer, depression and anxiety, and asthma; most notably depression and anxiety (PR = 1.7, 95% CI; 1.4-2.2). Determinants that were statistically significantly different between Aboriginal and non-Aboriginal Victorians included: a higher prevalence of psychosocial risk factors (psychological distress, food insecurity and financial stress); lower SES (not being employed and low income); lower social capital (neighbourhood tenure of less than one year, inability to get help from family, didn't feel valued by society, didn't agree most people could be trusted, not a member of a community group); and a higher prevalence of lifestyle risk factors (smoking, obesity and inadequate fruit intake). A higher proportion of Aboriginal Victorians sought help for a mental health related problem and had had a blood pressure check in the previous two years. We identified inequalities in health between Aboriginal and non-Aboriginal Victorians, most notably in the prevalence of depression and anxiety, and the social determinants of health (psychosocial risk factors, SES, and social capital). This has implications for evidence-based policy development and may inform the development of public health interventions.

    There remains a concern that Indigenous Australians have been over-researched without corresponding improvements in their health; this trend is applicable to most Indigenous populations globally. This debate article has a dual purpose: 1) to open a frank conversation about the value of research to Indigenous Australian populations; and 2) to stimulate ways of thinking about potential resolutions to the lack of progress made in the Indigenous research benefit debate. Capturing the meaning of research benefit takes the form of ethical value-oriented methodological considerations in the decision-making processes of Indigenous research endeavours. Because research practices come from Western knowledge bases, attaining such positions in research means reconciling both Indigenous and Western knowledge systems to produce new methodologies that guide planning, evaluating and monitoring of research practices as necessary. Increasingly, more sophisticated performance measures have been implemented to ensure academic impact and benefits are captured. Assessing societal and other non-academic impacts and benefits however, has not been accorded corresponding attention. Research reform has only focussed on research translation in more recent years. The research impact debate must take account of the various standards of accountability (to whom), impact priorities (for whom), positive and negative impacts, and biases that operate in describing impact and measuring benefit. A perennial question in Indigenous research discourse is whether the abundance of research conducted; purportedly to improve health, is justified and benefits Indigenous people in ways that are meaningful and valued by them. Different research stakeholders have different conceptions of the value and nature of research, its conduct, what it should achieve and the kinds of benefits expected. We need to work collaboratively and listen more closely to the voice of Indigenous Australians to better understand, demonstrate and measure health research benefits. The authors conclude that as an imperative, a systematic benefit assessment strategy that includes identification of research priorities and planning, monitoring and evaluation components needs to be developed and implemented across research projects. In Indigenous health research, this will often mean adopting a benefit-led approach by changing the way research is done and preferencing alternative research methodologies. As a point of departure to improving impact and reaching mutually beneficial outcomes for researchers and partners in Indigenous health research, we need to routinise the assessment of benefit from outset of research as one of the standards toward which we work.

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 Rate coefficients (k5 for the title reaction were obtained using pulsed laser photolytic generation of OH coupled to its detection by laser-induced fluorescence (PLP–LIF. More than 80 determinations of k5 were carried out in nitrogen or air bath gas at various temperatures and pressures. The accuracy of the rate coefficients obtained was enhanced by in situ measurement of the concentrations of both HNO3 reactant and NO2 impurity. The rate coefficients show both temperature and pressure dependence with a rapid increase in k5 at low temperatures. The pressure dependence was weak at room temperature but increased significantly at low temperatures. The entire data set was combined with selected literature values of k5 and parameterised using a combination of pressure-dependent and -independent terms to give an expression that covers the relevant pressure and temperature range for the atmosphere. A global model, using the new parameterisation for k5 rather than those presently accepted, indicated small but significant latitude- and altitude-dependent changes in the HNO3 ∕ NOx ratio of between −6 and +6 %. Effective HNO3 absorption cross sections (184.95 and 213.86 nm, units of cm2 molecule−1 were obtained as part of this work: σ213.86  =  4.52−0.12+0.23  ×  10−19 and σ184.95  =  1.61−0.04+0.08  ×  10−17.

  5. Assessing site formation and assemblage integrity through stone tool refitting at Gruta da Oliveira (Almonda karst system, Torres Novas, Portugal: A Middle Paleolithic case study.

    Directory of Open Access Journals (Sweden)

    Marianne Deschamps

    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.

  10. Assessing and Validating an Educational Resource Package for Health Professionals to Improve Smoking Cessation Care in Aboriginal and Torres Strait Islander Pregnant Women

    Directory of Open Access Journals (Sweden)

    2017-09-01

    Full Text Available Australian Aboriginal pregnant women have a high smoking prevalence (45%. Health professionals lack adequate educational resources to manage smoking. Resources need to be tailored to ensure saliency, cultural-sensitivity and account for diversity of Indigenous populations. As part of an intervention to improve health professionals’ smoking cessation care in Aboriginal pregnant women, a resource package was developed collaboratively with two Aboriginal Medical Services. The purpose of this study was to assess and validate this resource package. A multi-centred community-based participatory 4-step process (with three Aboriginal Medical Services from three Australian states, included: (1 Scientific review by an expert panel (2 ‘Suitability of Materials’ scoring by two Aboriginal Health Workers (3 Readability scores (4 Focus groups with health professionals. Content was analysed using six pre-determined themes (attraction, comprehension, self-efficacy, graphics and layout, cultural acceptability, and persuasion, with further inductive analysis for emerging themes. Suitability of Material scoring was adequate or superior. Average readability was grade 6.4 for patient resources (range 5.1–7.2, and 9.8 for health provider resources (range 8.5–10.6. Emergent themes included ‘Getting the message right’; ‘Engaging with family’; ‘Needing visual aids’; and ‘Requiring practicality under a tight timeframe’. Results were presented back to a Stakeholder and Consumer Aboriginal Advisory Panel and resources were adjusted accordingly. This process ensured materials used for the intervention were culturally responsive, evidence-based and useful. This novel formative evaluation protocol could be adapted for other Indigenous and culturally diverse interventions. The added value of this time-consuming and costly process is yet to be justified in research, and might impact the potential adaption by other projects.

    This study evaluated the microstructures and the resistance of AISI 316L, 410S and 444 stainless steel welded joints to heavy crude oil corrosion, using the AWS E309MoL-16 electrode. The above mentioned stainless steel plates were welded applying three energy levels (6; 9 and 12kJ/cm). Experimental sample forms were obtained from the welded plates, which were thermally treated at 200 and 300 deg C and immersed (annealed) in heavy crude oil. The techniques of optical microscopy (OM), scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX) were employed to make the microstructure evaluation, in addition to the surface characterization and the corrosion product identification. It was concluded that the welding thermal cycle is sufficient to cause metallurgic alterations in the region of the heat-affected zone (HAZ), making the region more susceptible to corrosion. It was also observed that the rate of corrosion varied according to the welding parameters applied. (author)

    This work aims to present a method which permits an optimized design of the transmission towers insulating structures for a specified risk-of-failure, under different types of electrical stresses to which they might be submitted, considering statistical probabilities of unfavorable atmospheric conditions (pressure, temperature, humidity and wind speeds), amplitudes of voltage surges and its distribution along the line, as well as the number of parallel tower gaps and insulator swings. Convention design methods are used for a preliminary design based on all types of overvoltage stresses. The risk of failure is calculated considering the atmospheric conditions along the line route. Adjustments should be made until the design can be considered satisfactory and its risk-of-failure complies to the specified one. In order to complete the tower insulation coordination project, an evaluation of lightning impulse performance should be made. 24 refs., 41 figs., 6 tabs.

    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)

Afetou apenas indivíduos jovens, imaturos ou em maturação, com comprimentos totais entre 200 e 250 mm, atingindo um ou ambos os olhos, nas varias combinações possíveis. O caso estudado não se trata de catarata parasítica, não se verificando infestação do cristalino por larvas de trematodas, não sendo também causada por bactérias. Parecem existir dois caminhos do processo, caracterizando os tipos "radial" e "difuso". A análise dos padrões eletroforéticos de proteínas totais de cristalinos cataráticos permitiu determinar cinco fases de evolução, desde parcial inicial até total, durante as quais ocorrem alterações marcantes, tanto na concentração de proteínas totais solúveis nos extratos como na concentração relativa das oito frações proteicas que se grupam em quatro conjuntos nos padrões de cristalinos normais. Verificou-se aumento na concentração relativa dos conjuntos I (mais catódico e II e decréscimo dos conjuntos III e IV (mais anódico, com o desaparecimento das duas frações deste último conjunto nas fases finais do processo. Não foram constatadas alterações na concentração relativa dos quatro conjuntos, quando comparados cristalinos de indivíduos normais e cristalinos normais de indivíduos portadores, o que significa que a ocorrência de catarata em um dos olhos não causa quaisquer alterações naquele não afetado. Os resultados sugerem que a catarata se constitui em causa de mortalidade natural para a espécie nessa área e que seu desenvolvimento deve estar ligado a algum fator fisiológico ou metabólico induzido por condições ambientais.The presence of specimens of Micropogonias funieri suffering from cataracts was observed in the area occupied by the population I (Vazzoler, 1971. The frequency and distribution of these specimens were analysed and the electrophoretic patterns of soluble eye-lens proteins were determined. This cataract is not of parasitic origin and was rare in specimens from the coastal area. In the lagunar region it occurs mainly in specimens of the River Baguagu, from April to November. Only young fish (200 to 250 mm in imature or in maturation stages were affected. Two main pathways of evolution in the process seems to occur with a "radial" and a "difuse" type. The analysis of electrophoretic patterns showed 5 steps of evolution with remarkable alterations on the concentration of total soluble proteins as well as on the relative concentration of 8 proteic fractions grouped in 4 agregates in electropherograms, There is an increase in the relative concentration of the agregate I (more cathodic and II, and a decrease of the III and IV (anodic with the disappearance of the last two fractions of the latter in the final stages of the process. No alterations were determined in the relative concentrations of these agregates when comparing eye-lens of normal specimens with normal eye-lens of affected fish suggesting that the occurence of cataract in one eye does not cause any alteration in the normal eye. The results suggest that cataract may be the cause of natural mortality in the area, and its incidence may be due to a physiological or metabolic factor induced by environmental conditions.

    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 Sporobolus assemblages, compared to high retention and preservation of organic inputs in the Juncus assemblage.

    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.

Os participantes envolvidos nessas práticas são quase sempre movidos pelo desejo de diálogo, de não domínio, de emancipação. Sem a ilusão de que os limites entre universidade-escola possam ser completamente apagados, o que se discute aqui é o fortalecimento de uma agenda de pesquisa em Lingüística Aplicada que, sendo atividade crítico-praxiológica, promova unidade na multiplicidade, convergência na pluralidade, ética na não-indiferença.This text aims at discussing the dialectics between research practice in Applied Linguistics and EFL teacher education initiatives. Such a discussion is illustrated with possibilities of new territories drawn in activities designed to overcome historical power relations and the privilege of academic knowledge over everyday knowledge. Participants involved in such social practices are motivated by a dialogical emancipatory desire. Bearing in mind that the university-school boundaries cannot be fully eradicated, this article argues for the strengthening of a research agenda that, being a critical-praxiological activity, nurtures singleness within multiplicity, convergence within pluralism, ethics within non-indifference.

    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.

  8. High altitude C(4) grasslands in the northern Andes: relicts from glacial conditions?

    2001-06-01

    The altitudinal vegetation distribution in the northern Andes during glacial time differed from the present-day conditions as a result of temperature and precipitation change. New evidence indicate that as a response to a reduced atmospheric partial CO(2) pressure (pCO(2)), the competitive balance between C(3) and C(4) plants have changed. Effects may have remained virtually undetected in pollen records, but can be observed using a stable carbon isotope analysis. Vegetation dominated by C(4) taxa, belonging to the families Cyperaceae (e.g. Bulbostylis and Cyperus) and Poaceae (e.g. Muhlenbergia, Paspalum and Sporobolus), may have been able to replace for a significant part the modern type C(3) taxa (e.g. species belonging to Carex, Rhynchospora, Aciachne, Agrostis, Calamagrostis, and Chusquea). Impact of reduced glacial atmospheric pCO(2) levels and lower glacial temperatures on the composition and the elevational distribution of the vegetation types is discussed. The present high Andean vegetation communities may differ from the glacial equivalents (non-modern analogue situation). We identified dry Sporobolus lasiophyllus tussock grassland and Arcytophyllum nitidum dwarfshrub paramo as the possible relict communities from glacial time. The effect on previous estimates of paleo-temperatures is estimated to be small.

    Along with the various system development for the accelerator, it was necessary to develop the instrumentation facility for the cyclotron. It started with the development of various vacuum instruments like ionization gauge control unit for measurement of pressure from 10 -4 torr to 10 -9 torr, discharge gauge control unit from 10 -4 torr to 10 -7 torr, thermocouple gauge control unit from 1 torr to 10 -3 torr. Process control instrumentation includes temperature measurement for freon cooled baffle and als o for low conductivity water. Control console required various digital panel meters for measurement of various parameters of the cyclotron. Various radiation monitoring instruments are also taken care of by the instrumentation facility. This paper describes in brief these various instruments. (author). 3 f igs

    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 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.

    Full Text Available In this study, we concentrate on modelling gross primary productivity using two simple approaches to simulate canopy photosynthesis: "big leaf" and "sun/shade" models. Two approaches for calibration are used: scaling up of canopy photosynthetic parameters from the leaf to the canopy level and fitting canopy biochemistry to eddy covariance fluxes. Validation of the models is achieved by using eddy covariance data from the LBA site C14. Comparing the performance of both models we conclude that numerically (in terms of goodness of fit and qualitatively, (in terms of residual response to different environmental variables sun/shade does a better job. Compared to the sun/shade model, the big leaf model shows a lower goodness of fit and fails to respond to variations in the diffuse fraction, also having skewed responses to temperature and VPD. The separate treatment of sun and shade leaves in combination with the separation of the incoming light into direct beam and diffuse make sun/shade a strong modelling tool that catches more of the observed variability in canopy fluxes as measured by eddy covariance. In conclusion, the sun/shade approach is a relatively simple and effective tool for modelling photosynthetic carbon uptake that could be easily included in many terrestrial carbon models.Neste trabalho foi modelada a produtividade primária bruta através de duas técnicas simples para simular a fotossíntese no dossel: os modelos "folha-grande" e "sol/sombra". Para calibrar os modelos foram utilizados os parâmetros de fotossíntese da folha, estendidos à escala do dossel e um ajuste da bioquímica do dossel em relação à covariância de vórtices turbulentos. Os modelos foram validados com as medidas feitas através da técnica de covariância de vórtices turbulentos da estação C14 do projeto LBA. Ao comparar o desempenho de ambos os modelos, conclui-se que o modelo "sol/sombra" apresenta melhores resultados numericamente (do ponto de vista da qualidade do ajuste aos dados da estação C14 e qualitativamente (segundo a resposta residual às diferentes variáveis ambientais. Comparado ao modelo "sol/sombra", o modelo "folha-grande" tem menos precisão e não responde bem às variações na fração difusa da luz. O modelo "folha-grande" também apresenta resultados assimétricos em relação à temperatura do ar e ao déficit da pressão de vapor. O tratamento separado de folhas expostas ao sol e de folhas sombreadas, combinado à separação da incidência de luz direta e difusa, faz do modelo "sol/sombra" uma ferramenta de modelagem útil, capaz de reproduzir melhor a variabilidade de fluxos no dossel medidos pela técnica de covariância de vórtices turbulentos. Neste trabalho, mostramos também a importância de boas estimativas de radiação difusa e a necessidade de aprimoramento de tais medidas na região amazônica. Discutimos igualmente as dificuldades de mudança de escala desde a folha para o dossel e a importância de dados representativos para serem parametrizados nestes tipos de modelo. Em conclusão, o modelo "sol/sombra" mostrou-se relativamente simples e eficaz para modelar a fixação de carbono pela fotossíntese e poderia facilmente ser incluído em diferentes modelos de ciclo do carbono terrestre.

  19. 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. Eleocharis palustris, Elymus cinereus, Equisetum hyemale, Eriogonum compositum, Juniperus trichocarpa, Phalaris arundinacea, Poa compressa.

    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.

    Changkun Dong; Ganapati Myneni

    2003-10-01

    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.

    Filous, A; Burdová, M; Malec, J

    1998-05-01

    In the introduction the authors describe a portable electronic tonometer Tono-pen XL and explain the principle of its function. After this follows a comparative study with Goldmann's applanation tonometry (AT) on 240 eyes in children aged 7 to 18 years. The mean value of the intraocular pressure (IOP) was 17.09 torr +/- 4.35 SD with AT and 16.46 torr +/- 4.04 SD when using the Tono-pen. Regression analysis revealed a very close correlation between the two methods of assessment (r = 0.925) with a high statistical significance (p < 0.0005). The difference as compared with AT values was constant, on average close to -0.68 torr in the whole range from 7 to 35 torr. The authors found also a significantly greater variability of values obtained by means of the Tono-pen (p = 0.0009), the mean scatter of individual values being 1.55 torr as compared with 1.25 torr in AT. However 97.1% of the eyes were within a range of 3 torr. The authors did not find a significant relationship between assessment by means of the Tono-pen and the doctor's experience. The unique advantage of Tono-pen as compared with all other methods of routine tonometry is the relatively accurate assessment of the IOP under irregular conditions of the cornea. It is also possible to take measurements in children where AT cannot be used.

    1992-01-01

    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

    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.

    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.

    1996-01-01

    Air breakdown induced by a high-power short-pulse microwave in the pressure range from 100 to 760 Torr was studied experimentally. The high-power microwaves with the peak power of 20 MW, frequency of 12 GHz and pulse duration of 14 ns was irradiated to a pair of needle and plane electrodes biased at the potential less than the breakdown voltage. The gap separation between the needle and plane electrodes was 1.5 cm. Microwave-induced breakdowns occurred at the pressure range from 150 to 760 Torr for negative potential and from 150 to 350 Torr for positive polarity at the presence of corona discharges. At the pressure range less than 150 Torr, the microwave-induced breakdown occurred without corona discharge at both polarities. (author). 5 figs., 4 refs

    1978-01-01

    A tunable diode laser absorption spectrometer with resolution of about 0.0001/cm was used to record air-broadened spectra of CC12F2 in two regions near 922.8/cm and 921.7/cm. In the 922.8/cm region the structure shows good intensity contrast at pressures corresponding to upper atmospheric pressures. The absorption features have a spacing of 0.014/cm, which is sufficiently wide to retain spectral structure at pressures as high as 48 torr or altitudes as low as 19 km. The apparent broadening is 2 MHz/torr. The single-line broadening coefficient for CC12F2 can be estimated to be 8 + or - 2 MHz/torr FWHM. In the 921.7/cm region the high-resolution structure is discernible up to 24 torr, but the intensity contrast is not sufficiently strong to be of use in analysis of stratospheric spectra.

    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.

    Laboratory spectra of CCL2F2 in the 10.8 micron region was recorded, using a tuneable diode laser spectrometer. Effects of air-broadening at pressures up to 48 Torr show that spectral structure should be exhibited under high resolution at altitudes as low as 19 Km. The single line, pressure-broadening coefficient for CCL2F2 was estimated to be 8 MHz/Torr FWHM.

    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...
