Full Text Available During the period from 1964 to 1999 Saudi Arabian species of Salicornia were wrongly treated under the European species, S. europaea L. Recent explorations proved that there are two separate allopatric species of Salicornia in Saudi Arabia, one inhabiting the inland salt-marshes of the Najd (highlands and the other inhabiting the Arabian Gulf Coast (lowlands. Morphological, ecological and exploratory studies confirm that they are two distinct species. The two species differ in features of bark, axillary spikes, basal vegetative segment(s of spike, fertile segments, colour of senescent plants, and flowering, fruiting and germination phenology. As both the species have been described earlier from Iran, they are now new records for Saudi Arabia. The species are, S. persica ssp. iranica (Akhani Kadereit & Piirainen and S. sinus-persica Akhani. S. sinus-persica, of which the status was thought doubtful has been confirmed. Both the species have been described and illustrated. Each species comprises a number of polymorphs. As leaves and flowers are rudimentary, confusing species circumscriptions, a proliferation of binomials has resulted in the taxonomy of Salicornia. To mitigate such confusion, the full range of variability of the Saudi Arabian species has been documented.

The nutritional compositions of two edible red (Gracilaria salicornia) and green (Ulva lactuca) seaweeds were determined to evaluate their possible uses as potential food ingredients. In general, these species contained limited amounts of lipids ranging between 0.99 and 2.00 g 100 g(-1) dry weight) and considerably high amount of minerals, especially in G. salicornia (38.91 g 100 g(-1) d.w.). The crude protein values varied between 9.58 and 10.69 g 100 g(-1) d.w. Amounts for total amino acids were 889.78 ± 22.64 mg g(-1) protein d.w. in G. salicornia and 543.3 ± 15.14 mg g(-1) protein d.w. in U. lactuca. The most abundant fatty acids were C12:0, C16:0, C20:4 ω6 and C22:5 ω3, in addition to C18:1 in G. salicornia. Both seaweed species were balanced sources of ω3 and ω6 fatty acids with a ratio of ω6/ω3 that varied between 1.2 and 1.17. Between the seaweeds investigated, high levels of K (2414.02-11 380.06 mg 100 g(-1) d.w.) were observed and the amounts of Ca, Na and Fe were higher than those reported for land plants. Thus, G. salicornia and U. lactuca may be utilised as value-added products for human nutrition purposes. Copyright © 2012 Society of Chemical Industry.

Salicornia and Sarcocornia are almost identical halophytes whose edible succulent shoots hold promise for commercial production in saline water. Enhanced sulfur nutrition may be beneficial to crops naturally grown on high sulfate. However, little is known about sulfate nutrition in halophytes. Here we show that Salicornia europaea (ecotype RN) exhibits a significant increase in biomass and organic-S accumulation in response to supplemental sulfate, whereas Sarcocornia fruticosa (ecotype VM) does not, instead exhibiting increased sulfate accumulation. We investigated the role of two pathways on organic-S and biomass accumulation in Salicornia and Sarcoconia: the sulfate reductive pathway that generates Cys and l-Cys desulfhydrase that degrades Cys to H2S, NH3, and pyruvate. The major function of O-acetyl-Ser-(thiol) lyase (OAS-TL; EC 2.5.1.47) is the formation of l-Cys, but our study shows that the OAS-TL A and OAS-TL B of both halophytes are enzymes that also degrade l-Cys to H2S. This activity was significantly higher in Sarcocornia than in Salicornia, especially upon sulfate supplementation. The activity of the sulfate reductive pathway key enzyme, adenosine 5′-phosphosulfate reductase (APR, EC 1.8.99.2), was significantly higher in Salicornia than in Sarcocornia. These results suggest that the low organic-S level in Sarcocornia is the result of high l-Cys degradation rate by OAS-TLs, whereas the greater organic-S and biomass accumulation in Salicornia is the result of higher APR activity and low l-Cys degradation rate, resulting in higher net Cys biosynthesis. These results present an initial road map for halophyte growers to attain better growth rates and nutritional value of Salicornia and Sarcocornia. PMID:28743765

Gracilaria salicornia and Gelidium latifolium have high content of agar and potential to be use as raw material for bioethanol. In bioethanol production, one of the processes level is enzyme hydrolysis. Various microorganisms, one of which is bacteria, can carry out the enzyme hydrolysis. Bacteria that degrade the cell walls of macroalgae and produce an agarase enzyme called agarolytic bacteria. The purpose of this study was to isolate bacteria from macroalgae G. salicornia and G. latifolium, which has the highest agarase enzyme activities, and to obtain agarase enzyme characteristic for bioethanol production. There are two isolates bacteria resulted from G. salicornia that are N1 and N3 and there are two isolates from G. latifolium that are BSUC2 and BSUC4. The result of agarase enzyme qualitative test showed that isolates bacteria from G. latifolium were greater than G. salicornia. The highest agarolitic index of bacteria from G. salicornia produced by isolate N3 was 2.32 mm and isolate N3 was 2.27 mm. Bacteria from G. latifolium produced by isolate BSUC4 was 4.28 mm and isolate BSUC2 was 4.18 mm, respectively. Agarase enzyme activities from isolates N1 and N3 were optimum working at pH 7 and temperature 30 °C, while from isolates BSUC4 was optimum at pH 7 and temperature 50 °C. This is indicated that the four bacteria are appropriate to hydrolyze macro alga for bioethanol production.

High salinity is a major abiotic stress that affects the growth and development of plants. This type of stress can influence flowering, the production of crops, defense mechanisms and other physiological processes. Previous studies have attempted to elucidate salt-tolerance mechanisms to improve plant growth and productivity in the presence of sodium chloride. One such plant that has been studied in detail is Salicornia, a well-known halophyte, which has adapted to grow in the presence of high salt. To further the understanding of how Salicornia grows and develops under high saline conditions, Salicornia herbacea (S. herbacea) was grown under varying saline concentrations (0, 50, 100, 200, 300, and 400mM), and the resulting phenotype, ion levels, and metabolites were investigated. The optimal condition for the growth of S. herbacea was determined to be 100mM NaCl, and increased salt concentrations directly decreased the internal concentrations of other inorganic ions including Ca 2+ , K + , and Mg 2+ . Metabolomics were performed on the roots of the plant as a systematic metabolomics study has not yet been reported for Salicornia roots. Using ethylacetate and methanol extraction followed by high resolution ultra-performance liquid chromatography coupled with mass spectrometry (UPLC-MS), 1793 metabolites were identified at different NaCl levels. Structural and functional analyses demonstrated that the concentration of 53 metabolites increased as the concentration of NaCl increased. These metabolites have been linked to stress responses, primarily oxidative stress responses, which increase under saline stress. Most metabolites can be classified as polyols, alkaloids, and steroids. Functional studies of these metabolites show that shikimic acid, vitamin K1, and indole-3-carboxylic acid are generated as a result of defense mechanisms, including the shikimate pathway, to protect against reactive oxygen species (ROS) generated by salt stress. This metabolite profiling

Seaweeds survive in marine waters with high sulfate concentration compared to those living at freshwater habitats. The cell wall polymer of Gracilaria spp. which supplies more than 50% of the world agar is heavily sulfated. Since sulfation reduces the agar quality, it is interesting to investigate the effects of sulfate deprivation on the sulfate contents of seaweed and agar, as well as the metabolic pathways of these seaweeds. In this study, two agarophytes G. changii and G. salicornia were treated under sulfate deprivation for 5 days. The sulfate contents in the seaweed/agar were generally lower in sulfate-deprivated samples compared to those in the controls, but the differences were only statistically significant for seaweed sample of G. changii and agar sample of G. salicornia. RNA sequencing (RNA-Seq) of sulfate-deprivated and untreated seaweed samples revealed 1,292 and 3,439 differentially expressed genes (DEGs; ≥1.5-fold) in sulfate-deprivated G. changii and G. salicornia, respectively, compared to their respective controls. Among the annotated DEGs were genes involved in putative agar biosynthesis, sulfur metabolism, metabolism of sulfur-containing amino acids, carbon metabolism and oxidative stress. These findings shed light on the sulfate deprivation responses in agarophytes and help to identify candidate genes involved in agar biosynthesis.

High-fat and high-salt intakes are among the major risks of chronic diseases including obesity, nonalcoholic fatty liver disease (NAFLD), and nonalcoholic steatohepatitis (NASH). Salicornia is a halophytic plant known to exert antioxidant, antidiabetic, and hypolipidemic effects, and Salicornia-extracted salt (SS) has been used as a salt substitute. In this study, the effects of SS and purified salt (PS) on the aggravation of NAFLD/NASH were compared. C57BL/6J male mice (8-wk-old) were fed a high-fat diet (HFD) for 6 mo and divided into 3 dietary groups, which were additionally fed HFD, HFD + SS, and HFD + PS for 13 wk. PS induced aggravation of NAFLD/NASH in HFD-fed mice. Although the actual salt intake was same between the PS and SS groups as 1% of the diet (extrapolated from the World Health Organization [WHO] guideline), SS induced less liver injury and hepatic steatosis compared to PS. The hepatic mRNA expressions of inflammatory cytokines and fibrosis marker were significantly lower in the SS group than the PS group. Oxidative stress is one of the major causes of inflammation in NAFLD/NASH. Results of the component analysis showed that the major polyphenols that exhibited antioxidant activity in the Salicornia water extract were ferulic acid, caffeic acid, and isorhamnetin. These results suggest that even the level of salt intake recommended by WHO can accelerate the progression of liver disease in obese individuals consuming HFD. It is proposed that SS can be a salt substitute for obese individuals who consume HFD. © 2017 Institute of Food Technologists®.

Halophytes classified under the common name of salicornia colonize salty and coastal environments across tidal inundation gradients. To unravel the role of tide-related regimes on the structure and functionality of root associated bacteria, the rhizospheric soil of Salicornia strobilacea (synonym of Halocnemum strobilaceum) plants was studied in a tidal zone of the coastline of Southern Tunisia. Although total counts of cultivable bacteria did not change in the rhizosphere of plants grown along a tidal gradient, significant differences were observed in the diversity of both the cultivable and uncultivable bacterial communities. This observation indicates that the tidal regime is contributing to the bacterial species selection in the rhizosphere. Despite the observed diversity in the bacterial community structure, the PGP potential of cultivable rhizospheric bacteria, assessed through in vitro and in vivo tests, was equally distributed along the tidal gradient. Root colonization tests with selected strains proved that halophyte rhizospheric bacteria (i) stably colonize S. strobilacea rhizoplane and the plant shoot suggesting that they move from the root to the shoot and (ii) are capable of improving plant growth. The versatility in the root colonization, the overall PGP traits and the in vivo plant growth promotion under saline condition suggest that such beneficial activities likely take place naturally under a range of tidal regimes.

Salinity severely affects plant growth and development causing crop loss worldwide. We have isolated a large number of salt-induced genes as well as unknown and hypothetical genes from Salicornia brachiata Roxb. (Amaranthaceae). This is the first description of identification of genes in response to salinity stress in this extreme halophyte plant. Salicornia accumulates salt in its pith and survives even at 2 M NaCl under field conditions. For isolating salt responsive genes, cDNA subtractive hybridization was performed between control and 500 mM NaCl treated plants. Out of the 1200 recombinant clones, 930 sequences were submitted to the NCBI database (GenBank accession: EB484528 to EB485289 and EC906125 to EC906292). 789 ESTs showed matching with different genes in NCBI database. 4.8% ESTs belonged to stress-tolerant gene category and approximately 29% ESTs showed no homology with known functional gene sequences, thus classified as unknown or hypothetical. The detection of a large number of ESTs with unknown putative function in this species makes it an interesting contribution. The 90 unknown and hypothetical genes were selected to study their differential regulation by reverse Northern analysis for identifying their role in salinity tolerance. Interestingly, both up and down regulation at 500 mM NaCl were observed (21 and 10 genes, respectively). Northern analysis of two important salt tolerant genes, ASR1 (Abscisic acid stress ripening gene) and plasma membrane H+ATPase, showed the basal level of transcripts in control condition and an increase with NaCl treatment. ASR1 gene is made full length using 5' RACE and its potential role in imparting salt tolerance is being studied.

Full Text Available Four new dicaffeoylquinic acid derivatives and two known 3-caffeoylquinic acid derivatives were isolated from methanol extracts using the aerial parts of Salicornia herbacea. The four new dicaffeoylquinic acid derivatives were established as 3-caffeoyl-5-dihydrocaffeoylquinic acid, 3-caffeoyl-5-dihydrocaffeoylquinic acid methyl ester, 3-caffeoyl-4-dihydrocaffeoylquinic acid methyl ester, and 3,5-di-dihydrocaffeoylquinic acid methyl ester. Their chemical structures were determined by nuclear magnetic resonance and electrospray ionization-mass spectroscopy (LC-ESI-MS. In addition, the presence of dicaffeoylquinic acid derivatives in this plant was reconfirmed by LC-ESI-MS/MS analysis. The isolated compounds strongly scavenged 1,1-diphenyl-2-picrylhydrazyl radicals and inhibited cholesteryl ester hydroperoxide formation during rat blood plasma oxidation induced by copper ions. These results indicate that the caffeoylquinic acid derivatives may partially contribute to the antioxidative effect of S. herbacea.

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

Torres Strait: A channel clearing project

Bankert, Stanley

1970-01-01

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

Full Text Available This article presents a study of the relation between the arts of literature and painting, from the interdisciplinary point of view. Focused on the structural analysis of Max Aub’s novel Jusep Torres Campanals, we will see how this work represents the translation of cubist painting’s aesthetics into the literary discourse. Through this analysis we will be able to prove how the narrative discourse’s decompositive technique, as used in a cubist painting, shows Jusep Torres Campanals as a fascinating dialogic dimension between truth and falseness, between painting and writing. Setting the reader again before the reflection of the old dialogue between literature and painting.Este artículo se presenta desde la perspectiva interdisciplinar del estudio de las relaciones entre dos artes, la Literatura y la Pintura, centrándose en el análisis estructural de la novela de Max Aub, Jusep Torres Campanals, tras el que observaremos cómo esta obra supone la traslación de la estética de la pintura cubista al discurso literario. A lo largo del análisis podremos comprobar, pues, cómo la técnica de descomposición del discurso narrativo, a la manera de un cuadro cubista, convierte a Jusep Torres Campanals, en un fascinante espacio de diálogo entre la verdad y la mentira, la pintura y la escritura, situándonos de nuevo ante la reflexión del antiguo diálogo entre la Literatura y la Pintura.

The TorR High-Affinity Binding Site Plays a Key Role in Both torR Autoregulation and torCAD Operon Expression in Escherichia coli

2000-01-01

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 ...

Full Text Available Salicornia ramosissima J. Woods is a salt tolerant plant currently used in the human diet, whose genus not only displays great potential as a crop plant in deserts and highly saline soils, but also has value in traditional medicine and exhibits promising biological activities. The present study was designed to evaluate the effect of S. ramosissima ethanolic extract on carbon tetrachloride (CCl4-induced testicular damage in a mouse model and identify secondary metabolites present in the tested extract. The histopathological analysis showed that the treatment with the ethanolic extract prior to CCl4 administration prevented significantly the architectural disorder of seminiferous epithelium and germ cell exfoliation. The phytochemical study allowed the identification of known phenolic and aliphatic compounds [ethyl linolenoate (1, sitostanol (2, octadecyl (3 and eicosanyl (4 (E-ferulates, ethyl (E-2-hydroxycinnamate (5, scopoletin (6, a triacylglycerol of tetracosanoic acid (7], and three new compounds: saliramoester, a long chain triester (8, saliramophenone, a propiophenone derivative (9 and saliramopyrrole a pyrrole-3-carbaldehyde derivative (10. Their chemical structures were elucidated using detailed spectroscopic studies (1D and 2D NMR and MS. These results enhance the value of S. ramosissima as an excellent source of structurally interesting phytochemicals and as protective agent against testicular toxicity.

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

Swain, Lindy S; Barclay, Lesley

2015-01-01

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

The current study deals with the synthesis of gold nanoparticles (AuNPs) using Salicornia brachiata (Sb) and evaluation of their antibacterial and catalytic activity. The SbAuNPs showed purple color with a characteristic surface plasmon resonance peak at 532 nm. Scanning electron microscopy and transmission electron microscopy revealed polydispersed AuNPs with the size range from 22 to 35 nm. Energy dispersive X-ray and thin layer X-ray diffraction analysis clearly shows that SbAuNPs was pure and crystalline in nature. As prepared gold nanoparticles was used as a catalyst for the sodium borohydride reduction of 4-nitro phenol to 4-amino phenol and methylene blue to leucomethylene blue. The green synthesized nanoparticles exhibited potent antibacterial activity against the pathogenic bacteria, as evidenced by their zone of inhibition. In addition, we showed that the SbAuNPs in combination with the regular antibiotic, ofloxacin, exhibit superior antibacterial activity than the individual.

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

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

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.

TORR system polishes oily water clean

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

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

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.

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

Soil salinity is a major abiotic stress that limits agriculture productivity worldwide. Salicornia europaea is a succulent annual euhalophyte and one of the most salt tolerant plant species. The elucidation of its salt tolerance mechanism is of significance for generating salt-tolerant crops. In this study, we provided high resolution of proteome reference maps of S. europaea shoot and obtained evidence on the salt tolerance mechanism by analyzing the proteomic responses of this plant to high salinity. Our results demonstrated significant variations existed in 196 out of 1880 protein spots detected on CBB stained 2-DE gels. Of these, 111 proteins were identified by mass spectrometry. Among them, the majority was energy production and conversion related proteins, followed by photosynthesis and carbohydrate metabolism associated enzymes. Analysis of protein expression patters revealed that energy production and ion homeostasis associated proteins played important roles for this plant salt tolerance ability. Hierarchical clustering results revealed many proteins were involved in S. europaea salt tolerance mechanism as a dynamic network. Finally, based on our proteomic results, we brought forward a possible schematic representation of mechanism associated with the systematic salt tolerance phenotype in S. europaea.

In order to obtain a salt-tolerant perennial alfalfa (Medicago sativa L.), we transferred the halophyte Salicornia europaea L. Na(+)/H(+) antiporter gene, SeNHX1, to alfalfa by using the Agrobacterium-mediated transformation method. The transformants were confirmed by both PCR and RT-PCR analyses. Of 197 plants that were obtained after transformation, 36 were positive by PCR analysis using 2 primer pairs for the CaMV35S-SeNHX1 and SeNHX1-Nos fragments; 6 plants survived in a greenhouse. RT-PCR analysis revealed that SeNHX1 was expressed in 5 plants. The resultant transgenic alfalfa had better salt tolerance. After stress treatment for 21 days with 0.6% NaCl, the chlorophyll and MDA contents in transgenic plants were lower, but proline content and SOD, POD, and CAT activities were higher than those in wild-type plants. These results suggest that the salt tolerance of transgenic alfalfa was improved by the overexpression of the SeNHX1 gene.

Salicornia herbacea L. is a halophyte that grows in salt marshes and contains significant amounts of salts and minerals. Because it is known as a folk medication to treat diseases, various processed products such as powder, globular type of powder, laver and extract have been developed. However, it is difficult to process as a drink because of its high salinity. In the present study, glasswort vinegar (GV) containing high amounts of organic acids and minerals was developed via two-step fermentation with unpolished rice substrates and investigated its antioxidant and anti-fatigue activities. GV showed various free radical scavenging effects, reducing power, oxidized-LDL inhibition and superoxide dismutase-like activities. Compared with the control group (orally administered 7 g kg(-1) distilled water), the GV supplementation group showed increased running endurance and had higher glycogen accumulation in liver and muscles of rats exhausted by exercise. Furthermore, the GV-administered group demonstrated significantly elevated lactate and ATP metabolism, promoting enzyme activities such as muscle creatine kinase and lactate dehydrogenase, whereas serum fatigue biomarkers such as ammonia, lactate and inorganic acid were markedly decreased. These results indicate that GV can be used as a functional food for the development of a dietary beverage to alleviate fatigue. © 2015 Society of Chemical Industry.

Salinity is a critical environmental factor that adversely affects crop productivity. Halophytes have evolved various mechanisms to adapt to saline environments. Salicornia europaea L. is one of the most salt-tolerant plant species. It does not have special salt-secreting structures like a salt gland or salt bladder, and is therefore a good model for studying the common mechanisms underlying plant salt tolerance. To identify candidate genes encoding key proteins in the mediation of salt tolerance in S. europaea, we performed a functional screen of a cDNA library in yeast. The library was screened for genes that allowed the yeast to grow in the presence of 1.3 M NaCl. We obtained three full-length S. europaea genes that confer salt tolerance. The genes are predicted to encode (1) a novel protein highly homologous to thaumatin-like proteins, (2) a novel coiled-coil protein of unknown function, and (3) a novel short peptide of 32 residues. Exogenous application of a synthetic peptide corresponding to the 32 residues improved salt tolerance of Arabidopsis. The approach described in this report provides a rapid assay system for large-scale screening of S. europaea genes involved in salt stress tolerance and supports the identification of genes responsible for such mechanisms. These genes may be useful candidates for improving crop salt tolerance by genetic transformation.

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

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

Directory of Open Access Journals (Sweden)

2013-03-01

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.

Rem Koolhaas y la nueva Babel. De la torre metropolitana al monumento al vacío

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

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

Science.gov (United States)

Harris, Peter T.

1991-07-01

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

2016-01-01

About 1000 salt-responsive ESTs were identified from an extreme halophyte Salicornia brachiata. Among these, a novel salt-inducible gene SbSLSP (Salicornia brachiata SNARE-like superfamily protein), showed up-regulation upon salinity and dehydration stress. The presence of cis-regulatory motifs related to abiotic stress in the putative promoter region supports our finding that SbSLSP gene is inducible by abiotic stress. The SbSLSP protein showed a high sequence identity to hypothetical/uncharacterized proteins from Beta vulgaris, Spinacia oleracea, Eucalyptus grandis, and Prunus persica and with SNARE-like superfamily proteins from Zostera marina and Arabidopsis thaliana. Bioinformatics analysis predicted a clathrin adaptor complex small-chain domain and N-myristoylation site in the SbSLSP protein. Subcellular localization studies indicated that the SbSLSP protein is mainly localized in the plasma membrane. Using transgenic tobacco lines, we establish that overexpression of SbSLSP resulted in elevated tolerance to salt and drought stress. The improved tolerance was confirmed by alterations in a range of physiological parameters, including high germination and survival rate, higher leaf chlorophyll contents, and reduced accumulation of Na(+) ion and reactive oxygen species (ROS). Furthermore, overexpressing lines also showed lower water loss, higher cell membrane stability, and increased accumulation of proline and ROS-scavenging enzymes. Overexpression of SbSLSP also enhanced the transcript levels of ROS-scavenging and signaling enzyme genes. This study is the first investigation of the function of the SbSLSP gene as a novel determinant of salinity/drought tolerance. The results suggest that SbSLSP could be a potential candidate to increase salinity and drought tolerance in crop plants for sustainable agriculture in semi-arid saline soil.

[The effects of TorR protein on initiation of DNA replication in Escherichia coli].

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

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

Moore, Ellie; Lawn, Sharon; Oster, Candice; Morello, Andrea

2017-01-01

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

Soil salinity is a major abiotic stress that limits agriculture productivity worldwide. Salicornia europaea is well adapted to extreme saline environments with more than 1,000 mM NaCl in the soil, so it could serve as an important model species for studying halophilic mechanisms in euhalophytes. To obtain insights into the molecular basis of salt tolerance, we present here the first extensive transcriptome analysis of this species using the Illumina HiSeq™ 2000. A total of 41 and 39 million clean reads from the salt-treated (Se200S) and salt-free (SeCKS) tissues of S. europaea shoots were obtained, and de novo assembly produced 97,865 and 101,751 unigenes, respectively. Upon further assembly with EST data from both Se200S and SeCKS, 109,712 high-quality non-redundant unigenes were generated with a mean unigene size of 639 bp. Additionally, a total of 3,979 differentially expressed genes (DEGs) were detected between the Se200S and SeCKS libraries, with 348 unigenes solely expressed in Se200S and 460 unigenes solely expressed in SeCKS. Furthermore, we identified a large number of genes that are involved in ion homeostasis and osmotic adjustment, including cation transporters and proteins for the synthesis of low-molecular compounds. All unigenes were functionally annotated within the COG, GO and KEGG pathways, and 10 genes were validated by qRT-PCR. Our data contains the extensive sequencing and gene-annotation analysis of S. europaea. This genetic knowledge will be very useful for future studies on the molecular adaptation to abiotic stress in euhalophytes and will facilitate the genetic manipulation of other economically important crops.

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. Particular success in reducing Aboriginal and Torres Strait Islander daily smoking was observed among younger age groups, with a decrease of 13.2 percentage points for 18–24-year-olds (95% CI 5.9, 20.4, 9.0 percentage points for 25–34-year-olds (95% CI 2.7, 15.3 and 8.7 percentage points for 35–44-year-olds (95% CI 2.6, 14.8.

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.

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.

Avery, R.; Elioff, T.; Grunder, H.

1981-03-01

Pressure of approx. 10 -10 torr is needed in the Bevatron to accelerate partially-stripped very-heavy ions (e.g. U 69+ ) in the Bevatron without significant loss due to interactions with the residual gas. This ultra-high vacuum will be achieved by installing (summer and fall 1981) a cryogenic liner, mostly 12 0 K, surrounding the Bevatron circulating beam. The novel construction features are presented along with results from successful tests of prototype sections. This is believed to be the largest application of cryogenic pumping to particle accelerators yet undertaken

Ten years of the Tiger: Aedes albopictus presence in Australia since its discovery in the Torres Strait in 2005

Directory of Open Access Journals (Sweden)

Andrew F. van den Hurk

2016-12-01

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

2017-09-19

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

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.

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

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

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

Appropriate health promotion for Australian Aboriginal and Torres Strait Islander communities: crucial for closing the gap.

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.

Using Indigenist and Indigenous methodologies to connect to deeper understandings of Aboriginal and Torres Strait Islander peoples' quality of life.

Science.gov (United States)

Kite, Elaine; Davy, Carol

2015-12-01

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

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

Full Text Available 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

2017-06-05

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

2013-08-01

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.

Watson, Karen; Young, Jeanine; Barnes, Margaret

2013-02-01

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

Measuring emotional and social wellbeing in Aboriginal and Torres Strait Islander populations: an analysis of a Negative Life Events Scale

2007-11-01

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

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

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

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

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

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

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

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

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.

Salinity causes multifarious adverse effects to plants. Plants response to salt stress involves numerous processes that function in coordination to alleviate both cellular hyperosmolarity and ion disequilibrium. A Na(+)/H(+) antiporter NHX1 gene has been isolated from a halophytic plant Salicornia brachiata in this study. Predicted amino acid sequence similarity, protein topology and the presence of functional domains conserved in SbNHX1 classify it as a plant vacuolar NHX gene. The SbNHX1 cDNA has an open reading frame of 1,683 bp, encoding a polypeptide of 560 amino acid residues with an estimated molecular mass 62.44 kDa. The SbNHX1 shows high amino acid similarity with other halophytic NHX gene and belongs to Class-I type NHXs. TMpred suggests that SbNHX1 contains 11 strong transmembrane (TM). Real time PCR analysis revealed that SbNHX1 transcript expresses maximum at 0.5 M. Transcript increases gradually by increasing the treatment duration at 0.5 M NaCl, however, maximum expression was observed at 48 h. The overexpression of SbNHX1 gene in tobacco plant showed NaCl tolerance. This study shows that SbNHX1 is a potential gene for salt tolerance, and can be used in future for developing salt tolerant crops.

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

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

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

High salinity and nitrogen (N) deficiency in soil are two key factors limiting crop productivity, and they usually occur simultaneously. Here we firstly found that H(+) -PPase is involved in salt-stimulated NO3 (-) uptake in the euhalophyte Salicornia europaea. Then, two genes (named SeVP1 and SeVP2) encoding H(+) -PPase from S. europaea were characterized. The expression of SeVP1 and SeVP2 was induced by salt stress and N starvation. Both SeVP1 or SeVP2 transgenic Arabidopsis and wheat plants outperformed the wild types (WTs) when high salt and low N occur simultaneously. The transgenic Arabidopsis plants maintained higher K(+) /Na(+) ratio in leaves and exhibited increased NO3 (-) uptake, inorganic pyrophosphate-dependent vacuolar nitrate efflux and assimilation capacity under this double stresses. Furthermore, they had more soluble sugars in shoots and roots and less starch accumulation in shoots than WT. These performances can be explained by the up-regulated expression of ion, nitrate and sugar transporter genes in transgenic plants. Taken together, our results suggest that up-regulation of H(+) -PPase favours the transport of photosynthates to root, which could promote root growth and integrate N and carbon metabolism in plant. This work provides potential strategies for improving crop yields challenged by increasing soil salinization and shrinking farmland. © 2015 John Wiley & Sons Ltd.

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.

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

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

Full Text Available 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.

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

Salinity severely affects plant growth and development. Plants evolved various mechanisms to cope up stress both at molecular and cellular levels. Halophytes have developed better mechanism to alleviate the salt stress than glycophytes, and therefore, it is advantageous to study the role of different genes from halophytes. Salicornia brachiata is an extreme halophyte, which grows luxuriantly in the salty marshes in the coastal areas. Earlier, we have isolated SbASR-1 (abscisic acid stress ripening-1) gene from S. brachiata using cDNA subtractive hybridisation library. ASR-1 genes are abscisic acid (ABA) responsive, whose expression level increases under abiotic stresses, injury, during fruit ripening and in pollen grains. The SbASR-1 transcript showed up-regulation under salt stress conditions. The SbASR-1 protein contains 202 amino acids of 21.01-kDa molecular mass and has 79 amino acid long signatures of ABA/WDS gene family. It has a maximum identity (73 %) with Solanum chilense ASR-1 protein. The SbASR-1 has a large number of disorder-promoting amino acids, which make it an intrinsically disordered protein. The SbASR-1 gene was over-expressed under CaMV 35S promoter in tobacco plant to study its physiological functions under salt stress. T(0) transgenic tobacco seeds showed better germination and seedling growth as compared to wild type (Wt) in a salt stress condition. In the leaf tissues of transgenic lines, Na(+) and proline contents were significantly lower, as compared to Wt plant, under salt treatment, suggesting that transgenic plants are better adapted to salt stress.

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

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

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.

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

Nanosized silver have been widely used in many applications, such as catalysis, photonics, sensors, medicine etc. Thus, there is an increasing need to develop high-yield, low cost, non-toxic and eco-friendly procedures for the synthesis of nanoparticles. Herein, we report an efficient, green synthesis of silver nanoparticles utilizing the aqueous extract of Salicornia brachiata, a tropical plant of the Chenopodiaceae family. Silver nanoparticles have been characterized by ultraviolet-visible spectroscopy, scanning electron microscopy and transmission electron microscopy. The morphology of the particles formed consists of highly diversified shapes like spherical, rod-like, prism, triangular, pentagonal and hexagonal pattern. However, addition of sodium hydroxide to the extract produces mostly spherical particles. The stable nanoparticles obtained using this green method show remarkable catalytic activity in the reduction of 4-nitro phenol to 4-amino phenol. The reduction catalyzed by silver nanoparticles followed the first-order kinetics, with a rate constant of, 0.6 × 10-2 s-1. The bactericidal activity of the synthesized silver nanoparticles against the pathogenic bacteria, Staphylococcus aureus, Staphylococcus aureus E, Bacillus subtilis and Escherichia coli, was also explored using REMA. The obtained results showed that the minimum inhibitory concentration required to induce bactericidal effect is lower than the control antibiotic, ciprofloxacin. In addition to these, the biogenic synthesized nanoparticles also exhibited excellent free radical scavenging activity.

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

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

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

Making every Australian count: challenges for the National Disability Insurance Scheme (NDIS) and the equal inclusion of homeless Aboriginal and Torres Strait Islander Peoples with neurocognitive disability.

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

DiamondTorre Algorithm for High-Performance Wave Modeling

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.

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

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

Social determinants and lifestyle risk factors only partially explain the higher prevalence of food insecurity among Aboriginal and Torres Strait Islanders in the Australian state of Victoria: a cross-sectional study

2014-01-01

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

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

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

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

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

Fluid and heat transport at the Torres del Paine laccolith (Patagonia/Chile)

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

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

Several reports have highlighted that many plant growth-promoting endophytic bacteria (PGPE) can assist their host plants in coping with various biotic and abiotic stresses. However, information about the PGPE colonizing in the halophytes is still scarce. This study was designed to isolate and characterize PGPE from salt-accumulating halophyte Salicornia europaea grown under extreme salinity and to evaluate in vitro the bacterial mechanisms related to plant growth promotion. A total of 105 isolates were obtained from the surface-sterilized roots, stems, and assimilation twigs of S. europaea. Thirty-two isolates were initially selected for their ability to produce 1-aminocyclopropane-1-carboxylate deaminase as well as other properties such as production of indole-3-acetic acid and phosphate-solubilizing activities. The 16S rRNA gene-sequencing analysis revealed that these isolates belong to 13 different genera and 19 bacterial species. For these 32 strains, seed germination and seedling growth in axenically grown S. europaea seedlings at different NaCl concentrations (50-500 mM) were quantified. Five isolates possessing significant stimulation of the host plant growth were obtained. The five isolates were identified as Bacillus endophyticus, Bacillus tequilensis, Planococcus rifietoensis, Variovorax paradoxus, and Arthrobacter agilis. All the five strains could colonize and can be reisolated from the host plant interior tissues. These results demonstrate that habitat-adapted PGPE isolated from halophyte could enhance plant growth under saline stress conditions.

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

The negative impact of salinity on plant growth and the survival of rhizosphere biota complicates the application of bioremediation to crude oil-contaminated saline soils. Here, a comparison was made between the remedial effect of treating the soil with Pseudomonas aeruginosa, a salinity tolerant hydrocarbon-degrading consortium in conjunction with either the halophyte Salicornia persica or the non-halophyte Festuca arundinacea. The effect of the various treatments on salinized soils was measured by assessing the extent of total petroleum hydrocarbon (TPH) degradation, the soil's dehydrogenase activity, the abundance of the bacteria and the level of phytotoxicity as measured by a bioassay. When a non-salinized soil was assessed after a treatment period of 120 days, the ranking for effectiveness with respect to TPH removal was F. arundinacea > P. aeruginosa > S. persica > no treatment control, while in the presence of salinity, the ranking changed to S. persica > P. aeruginosa > F. arundinacea > no treatment control. Combining the planting of S. persica or F. arundinacea with P. aeruginosa inoculation ("bioaugmentation") boosted the degradation of TPH up to 5-17%. Analyses of the residual oil contamination revealed that long chain alkanes (above C20) were particularly strongly degraded following the bioaugmentation treatments. The induced increase in dehydrogenase activity and the abundance of the bacteria (3.5 and 10 fold respectively) achieved in the bioaugmentation/S. persica treatment resulted in 46-76% reduction in soil phytotoxicity in a saline soil. The indication was that bioaugmentation of halophyte can help to mitigate the adverse effects on the effectiveness of bioremediation in a crude oil-contaminated saline soil.

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

Fatherhood in Australian Aboriginal and Torres Strait Islander communities: An Examination of Barriers and Opportunities to Strengthen the Male Parenting Role.

Reilly, Lyndon; Rees, Susan

2018-03-01

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

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

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

Steffen, Simone; Ball, Peter; Mucina, Ladislav; Kadereit, Gudrun

2015-01-01

Background and Aims Sarcocornia comprises about 28 species of perennial succulent halophytes distributed worldwide, mainly in saline environments of warm-temperate and subtropical regions. The genus is characterized by strongly reduced leaves and flowers, which cause taxonomic difficulties; however, species in the genus show high diversity in growth form, with a mat-forming habit found in coastal salt marshes of all continents. Sarcocornia forms a monophyletic lineage with Salicornia whose species are all annual, yet the relationship between the two genera is poorly understood. This study is aimed at clarifying the phylogenetic relationship between Sarcocornia and Salicornia, interpreting biogeographical and ecological patterns in Sarcocornia, and gaining insights into putative parallel evolution of habit as an adaptation to environmental factors. Methods A comprehensively sampled and dated phylogeny of Sarcocornia is presented based on nuclear ribosomal DNA (external transcribed spacer) and chloroplast DNA (atpB-rbcL, rpl32-trnL) sequences; representative samples of Salicornia were also included in the analyses. To infer biogeographical patterns, an ancestral area reconstruction was conducted. Key Results The Sarcocornia/Salicornia lineage arose during the Mid-Miocene from Eurasian ancestors and diversified into four subclades: the Salicornia clade, the American Sarcocornia clade, the Eurasian Sarcocornia clade and the South African/Australian Sarcocornia clade. Sarcocornia is supported as paraphyletic, with Salicornia nested within Sarcocornia being sister to the American/Eurasian Sarcocornia clade. The American and the South African/Australian Sarcocornia clade as well as the Salicornia clade were reconstructed to be of Eurasian origin. The prostrate, mat-forming habit arose multiple times in Sarcocornia. Conclusions Sarcocornia diversified in salt-laden environments worldwide, repeatedly evolving superficially similar prostrate, mat-forming habits that seem

A possible way solving the inclusion problem of the human liquid wastes containing sodium chloride into intrasystem mass exchange of bio-technical life support system (BTLSS) is selection of such species of greenery plants that can utilize sodium chloride, be edible for a human and have rather a high productivity. Our previous works showed that salt-accumulating halophyte Salicornia europaea L. was a promising candidate for sodium chloride inclusion into BTLSS mass exchange. However, with the aim of creation of more various human diet possibilities a set of greenery plants cultivated by the water culture method was estimated. Based on preliminary experiments the plants Brassica juncea L., Nasturtium officinale R. Br., Lepidium sativum angustifolia L. and Salicornia europaea L. were chosen as the investigation objects. The nutrient solution for greenery plant's cultivation was obtained after harvesting the wheat plants grown on the solution with mineralized human wastes' addition. The results of the first stage of the investigations carried out showed that plants of Brassica juncea and Lepidium sativum angustifolia are unpromising for their inclusion into BTLSS because of a set of physiological characteristics. On the next stage of investigations, an experimental model of closed ecosystem was created. For that purpose the plants of Salicornia europaea and Nasturtium officinale were introduced in the phototroph unit structure. It was determined that there was deficiency of main macronutrients for Salicornia europaea and Nasturtium officinale including sodium for Salicornia europaea. The deficiency had an effect on plants productivity and on carry-over of sodium from solution by Salicornia europaea. Thus in the future experiment it is necessary to carry out desalinization of solution by Salicornia europaea plants. Nasturtium officinale, that is rich in essential fatty acids and contributes into variety of human vegetable diet is planned to be cultivated by the

Reactive oxygen or nitrogen species are generated in the plant cell during the extreme stress condition, which produces toxic compounds after reacting with the organic molecules. The glutathione-S-transferase (GST) enzymes play a significant role to detoxify these toxins and help in excretion or sequestration of them. In the present study, we have cloned 1023 bp long promoter region of tau class GST from an extreme halophyte Salicornia brachiata and functionally characterized using the transgenic approach in tobacco. Computational analysis revealed the presence of abiotic stress responsive cis-elements like ABRE, MYB, MYC, GATA, GT1 etc., phytohormones, pathogen and wound responsive motifs. Three 5'-deletion constructs of 730 (GP2), 509 (GP3) and 348 bp (GP4) were made from 1023 (GP1) promoter fragment and used for tobacco transformation. The single event transgenic plants showed notable GUS reporter protein expression in the leaf tissues of control as well as treated plants. The expression level of the GUS gradually decreases from GP1 to GP4 in leaf tissues, whereas the highest level of expression was detected with the GP2 construct in root and stem under control condition. The GUS expression was found higher in leaves and stems of salinity or osmotic stress treated transgenic plants than that of the control plants, but, lower in roots. An efficient expression level of GUS in transgenic plants suggests that this promoter can be used for both constitutive as well as stress inducible expression of gene(s). And this property, make it as a potential candidate to be used as an alternative promoter for crop genetic engineering.

microRNAs (miRNAs) are implicated in plant development processes and play pivotal roles in plant adaptation to environmental stresses. Salicornia europaea, a salt mash euhalophyte, is a suitable model plant to study salt adaptation mechanisms. S. europaea is also a vegetable, forage, and oilseed that can be used for saline land reclamation and biofuel precursor production on marginal lands. Despite its importance, no miRNA has been identified from S. europaea thus far. Deep sequencing was performed to investigate small RNA transcriptome of S. europaea. Two hundred and ten conserved miRNAs comprising 51 families and 31 novel miRNAs (including seven miRNA star sequences) belonging to 30 families were identified. About half (13 out of 31) of the novel miRNAs were only detected in salt-treated samples. The expression of 43 conserved and 13 novel miRNAs significantly changed in response to salinity. In addition, 53 conserved and 13 novel miRNAs were differentially expressed between the shoots and roots. Furthermore, 306 and 195 S. europaea unigenes were predicted to be targets of 41 conserved and 29 novel miRNA families, respectively. These targets encoded a wide range of proteins, and genes involved in transcription regulation constituted the largest category. Four of these genes encoding laccase, F-box family protein, SAC3/GANP family protein, and NADPH cytochrome P-450 reductase were validated using 5'-RACE. Our results indicate that specific miRNAs are tightly regulated by salinity in the shoots and/or roots of S. europaea, which may play important roles in salt tolerance of this euhalophyte. The S. europaea salt-responsive miRNAs and miRNAs that target transcription factors, nucleotide binding site-leucine-rich repeat proteins and enzymes involved in lignin biosynthesis as well as carbon and nitrogen metabolism may be applied in genetic engineering of crops with high stress tolerance, and genetic modification of biofuel crops with high biomass and regulatable

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

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

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

HIF transport issues for P>10-3 Torr and Z>1

International Nuclear Information System (INIS)

Olson, C.L.

1986-01-01

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

High and fluctuating salinity is characteristic for coastal salt marshes, which strongly affect the physiology of halophytes consequently resulting in changes in stable isotope distribution. The natural abundance of stable isotopes (δ 13 C and δ 15 N) of the halophyte plant Salicornia brachiata and physico-chemical characteristics of soils were analysed in order to investigate the relationship of stable isotope distribution in different populations in a growing period in the coastal area of Gujarat, India. Aboveground and belowground biomass of S. brachiata was collected from six different populations at five times (September 2014, November 2014, January 2015, March 2015 and May 2015). The δ 13 C values in aboveground (-30.8 to -23.6 ‰, average: -26.6 ± 0.4 ‰) and belowground biomass (-30.0 to -23.1 ‰, average: -26.3 ± 0.4 ‰) were similar. The δ 13 C values were positively correlated with soil salinity and Na concentration, and negatively correlated with soil mineral nitrogen. The δ 15 N values of aboveground (6.7-16.1 ‰, average: 9.6 ± 0.4 ‰) were comparatively higher than belowground biomass (5.4-13.2 ‰, average: 7.8 ± 0.3 ‰). The δ 15 N values were negatively correlated with soil available P. We conclude that the variation in δ 13 C values of S. brachiata was possibly caused by soil salinity (associated Na content) and N limitation which demonstrates the potential of δ 13 C as an indicator of stress in plants.

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

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

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.

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

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.

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

2017-04-01

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

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.

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.

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.

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

The SbSOS1 gene from the extreme halophyte Salicornia brachiata enhances Na(+) loading in xylem and confers salt tolerance in transgenic tobacco.

Soil salinity adversely affects plant growth and development and disturbs intracellular ion homeostasis resulting cellular toxicity. The Salt Overly Sensitive 1 (SOS1) gene encodes a plasma membrane Na(+)/H(+) antiporter that plays an important role in imparting salt stress tolerance to plants. Here, we report the cloning and characterisation of the SbSOS1 gene from Salicornia brachiata, an extreme halophyte. The SbSOS1 gene is 3774 bp long and encodes a protein of 1159 amino acids. SbSOS1 exhibited a greater level of constitutive expression in roots than in shoots and was further increased by salt stress. Overexpressing the S. brachiata SbSOS1 gene in tobacco conferred high salt tolerance, promoted seed germination and increased root length, shoot length, leaf area, fresh weight, dry weight, relative water content (RWC), chlorophyll, K(+)/Na(+) ratio, membrane stability index, soluble sugar, proline and amino acid content relative to wild type (WT) plants. Transgenic plants exhibited reductions in electrolyte leakage, reactive oxygen species (ROS) and MDA content in response to salt stress, which probably occurred because of reduced cytosolic Na(+) content and oxidative damage. At higher salt stress, transgenic tobacco plants exhibited reduced Na(+) content in root and leaf and higher concentrations in stem and xylem sap relative to WT, which suggests a role of SbSOS1 in Na(+) loading to xylem from root and leaf tissues. Transgenic lines also showed increased K(+) and Ca(2+) content in root tissue compared to WT, which reflect that SbSOS1 indirectly affects the other transporters activity. Overexpression of SbSOS1 in tobacco conferred a high degree of salt tolerance, enhanced plant growth and altered physiological and biochemical parameters in response to salt stress. In addition to Na(+) efflux outside the plasma membrane, SbSOS1 also helps to maintain variable Na(+) content in different organs and also affect the other transporters activity indirectly. These

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.

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

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

Science.gov (United States)

Brough, M

2001-01-01

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

Muir-Torre Syndrome Presenting as Sebaceous Adenocarcinoma and Invasive MSH6-Positive Colorectal Adenocarcinoma

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.

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.

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

Full Text Available Cutaneous neoplasms including sebaceous tumors, keratoacanthomas, and basal cell carcinomas with sebaceous differentiation can be markers of internal malignancy associated with the Muir-Torre Syndrome (MTS. We report a 56-year-old man with a diagnosis of hereditary nonpolyposis colorectal cancer (HNPCC and ureteral transitional cell carcinoma who subsequently developed two sebaceous gland neoplasms and several keratoacanthomas, leading to the diagnosis of MTS. Our case highlights the clinical advantages of immunohistochemistry (IHC in identifying mutations in the mismatch repair (MMR genes responsible for both HNPCC and MTS. The importance of continued clinical suspicion in the dermatological assessment of patients with sebaceous neoplasms is emphasized.

The basic objective arising at use of mineralized human solid and liquid wastes serving as the source of mineral elements for plants cultivation in biological-technical life support systems appears to be NaCl presence in them. The given work is aimed at feasibility study of mineralized human metabolites' utilization for nutrient solutions' preparation for their further employment at a long-term cultivation of uneven-aged wheat and Salicornia europaea L. cenosis in a conveyer regime. Human solid and liquid wastes were mineralized by the "wet incineration" method developed by Yu. Kudenko. On their base the solutions were prepared which were used for cultivation of 5-aged wheat conveyer with the time step-interval of 14 days. Wheat was cultivated by hydroponics method on expanded clay aggregate. For partial demineralization of nutrient solution every two weeks after regular wheat harvesting 12 L of solution was withdrawn from the wheat irrigation tank and used for Salicornia europaea cultivation by the water culture method in a conveyer regime. The Salicornia europaea conveyer was represented by 2 ages with the time step-interval of 14 days. Resulting from repeating withdrawal of the solution used for wheat cultivation, sodium concentration in the wheat irrigation solution did not exceed 400 mg/l, and mineral elements contained in the taken solution were used for Salicornia europaea cultivation. The experiment lasted 7 months. Total wheat biomass productivity averaged 30.1 g*m-2*day-1 at harvest index equal to 36.8The work was carried out under support of SB RAS grant 132 and INTAS 05-1000008-8010

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

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

Full Text Available Abstract Background Soil salinity adversely affects plant growth and development and disturbs intracellular ion homeostasis resulting cellular toxicity. The Salt Overly Sensitive 1 (SOS1 gene encodes a plasma membrane Na+/H+ antiporter that plays an important role in imparting salt stress tolerance to plants. Here, we report the cloning and characterisation of the SbSOS1 gene from Salicornia brachiata, an extreme halophyte. Results The SbSOS1 gene is 3774 bp long and encodes a protein of 1159 amino acids. SbSOS1 exhibited a greater level of constitutive expression in roots than in shoots and was further increased by salt stress. Overexpressing the S. brachiata SbSOS1 gene in tobacco conferred high salt tolerance, promoted seed germination and increased root length, shoot length, leaf area, fresh weight, dry weight, relative water content (RWC, chlorophyll, K+/Na+ ratio, membrane stability index, soluble sugar, proline and amino acid content relative to wild type (WT plants. Transgenic plants exhibited reductions in electrolyte leakage, reactive oxygen species (ROS and MDA content in response to salt stress, which probably occurred because of reduced cytosolic Na+ content and oxidative damage. At higher salt stress, transgenic tobacco plants exhibited reduced Na+ content in root and leaf and higher concentrations in stem and xylem sap relative to WT, which suggests a role of SbSOS1 in Na+ loading to xylem from root and leaf tissues. Transgenic lines also showed increased K+ and Ca2+ content in root tissue compared to WT, which reflect that SbSOS1 indirectly affects the other transporters activity. Conclusions Overexpression of SbSOS1 in tobacco conferred a high degree of salt tolerance, enhanced plant growth and altered physiological and biochemical parameters in response to salt stress. In addition to Na+ efflux outside the plasma membrane, SbSOS1 also helps to maintain variable Na+ content in different organs and also affect the other

Congracilaria babae was first reported as a red alga parasitic on the thallus of Gracilaria salicornia based on Japanese materials. It was circumscribed to have deep spermatangial cavities, coloration similar to its host and the absence of rhizoids. We observed a parasitic red alga with morphological and anatomical features suggestive of C. babae on a Hydropuntia species collected from Sabah, East Malaysia. We addressed the taxonomic affinities of the parasite growing on Hydropuntia sp. based on the DNA sequence of molecular markers from the nuclear, mitochondrial and plastid genomes (nuclear ITS region, mitochondrial cox1 gene and plastid rbcL gene). Phylogenetic analyses based on all genetic markers also implied the monophyly of the parasite from Hydropuntia sp. and C. babae, suggesting their conspecificity. The parasite from Hydropuntia sp. has a DNA signature characteristic to C. babae in having plastid rbcL gene sequence identical to G. salicornia. C. babae is likely to have evolved directly from G. salicornia and subsequently radiated onto a secondary host Hydropuntia sp. We also recommend the transfer of C. babae to the genus Gracilaria and propose a new combination, G. babae, based on the anatomical observations and molecular data.

Soole, Rebecca; Kõlves, Kairi; De Leo, Diego

2014-12-01

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

The rock-cut tomb of Bolores (Torres Vedras: an interdisciplinary approach to understanding the social landscape of the Late Neolithic/Copper Age of the Iberian Peninsula

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.

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

The optimization of a tubular condensation cryopump for pressures below 10/sup -13/ Torr (for intersecting storage rings for protons)

CERN Document Server

Benvenuti, C

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.

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.

The role of succulent halophytes in the water balance of salt marsh rodents.

Coulombe, Harry N

1970-09-01

The role of succulent halophytes in the water balance and ecology of salt marsh rodents is dependent upon an evaluation of the composition of the available sources and the physiological properties of their potential consumers. Studies of the osmotic properties of succulent halophytes from southern California coastal salt marshes are presented, together with experiments regarding the utilization of Common Pickleweed (Salicornia virginica L.) by indigenous populations of cricetid rodents (harvest mouse Reithrodontomys megalotis limicola Von Bloecker, and meadow-mouse Microtus californicus stephensi Von Bloecker). These data are discussed in relation to other available information concerning the ecology of coastal salt marshes, particularly in western North America.Extruded sap of Common Pickleweed was found to have a mean total osmotic pressure (TOP) of 1,450 mOsm/liter, with an average chloride ion content of 876 mEq/liter (about 70% of the TOP). A related species, Salicornia subterminale, had a slightly lower TOP (1,300 mOsm/liter), of which about 29% was accounted for by chloride ion concentration. Sea Blight (Suaeda fruticosa) was the only species in which the TOP correlated with the distance from the tide level; sap TOP increased away from the lagoon's edge. In both Sea Blight and Common Pickle weed, TOP was not directly related to chloride content, indicating the importance of other osmotically active solutes.Harvest mice were placed on three experimental regimes: 1) millet seeds only, 2) pickleweed only, and 3) pickleweed and millet seed. Meadow mice were tested on the last regime only. Harvest mice survived best on a strict millet seed diet; when Salicornia was consumed to a detectable extent, the mice did not survive. Meadow mice, however, could survive using Salicornia as a dietary source in conjunction with seeds. Kidney electrolyte concentrating abilities indicated that harvest mice should be able to utilize pickleweed; this was not confirmed in my

Modeling Highly Buoyant Flows in the Castel Giorgio: Torre Alfina Deep Geothermal Reservoir

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.

The SbASR-1 gene, cloned from a halophyte Salicornia brachiata, encodes a plant-specific hydrophilic and stress responsive protein. The genome of S. brachiata has two paralogs of the SbASR-1 gene (2549 bp), which is comprised of a single intron of 1611 bp, the largest intron of the  abscisic acid stress ripening [ASR] gene family yet reported. In silico analysis of the 843-bp putative promoter revealed the presence of ABA, biotic stress, dehydration, phytohormone, salinity, and sugar responsive cis-regulatory motifs. The SbASR-1 protein belongs to Group 7 LEA protein family with different amino acid composition compared to their glycophytic homologs. Bipartite Nuclear Localization Signal (NLS) was found on the C-terminal end of protein and localization study confirmed that SbASR-1 is a nuclear protein. Furthermore, transgenic groundnut (Arachis hypogaea) plants over-expressing the SbASR-1 gene constitutively showed enhanced salinity and drought stress tolerance in the T1 generation. Leaves of transgenic lines exhibited higher chlorophyll and relative water contents and lower electrolyte leakage, malondialdehyde content, proline, sugars, and starch accumulation under stress treatments than wild-type (Wt) plants. Also, lower accumulation of H2O2 and O2.- radicals was detected in transgenic lines compared to Wt plants under stress conditions. Transcript expression of APX (ascorbate peroxidase) and CAT (catalase) genes were higher in Wt plants, whereas the SOD (superoxide dismutase) transcripts were higher in transgenic lines under stress. Electrophoretic mobility shift assay (EMSA) confirmed that the SbASR-1 protein binds at the consensus sequence (C/G/A)(G/T)CC(C/G)(C/G/A)(A/T). Based on results of the present study, it may be concluded that SbASR-1 enhances the salinity and drought stress tolerance in transgenic groundnut by functioning as a LEA (late embryogenesis abundant) protein and a transcription factor.

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 Australian REEFREP System: A Coastal Vessel Traffic Information Service and Ship Reporting System for the Torres Strait Region and the Inner Route of the Great Barrier Reef

MacDonald, John C.

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

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

Nevertheless, the species richness of seeds germinating from the seed bank of freshwater marshes was reduced more than in salt marshes, indicating that freshwater marsh regeneration may be more affected by hurricanes and/or sea level rise than salt marshes. From the perspective of short-term seed germination and recruitment following hurricanes, species recruitment is dependent on the post-disturbance conditions of water and salinity. ?? 2009 The Society of Wetland Scientists.

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 El presente ensayo estudia dos posturas diferentes a la hora de afrontar el reto de combinar lo humorístico y lo terrorífico en una misma obra: la literaria y la cinematográfica. En La torre de los siete jorobados, tanto el escritor, Emilio Carrere, como el director de cine, Edgar Neville, no renuncian a sus armas al tratar de transmitir a sus respectivos receptores dos sensaciones tan opuestas como son el terror y el humor. Sin embargo, sus enfoques a la hora de combinar estos dos elementos son diferentes: si en la novela el humor está al servicio del terror, en la película se produce un intercambio de papeles: el terror es el que está al servicio del humor. Así pues, el objetivo principal de este estudio es demostrar que la adaptación cinematográfica puede conservar perfectamente el espíritu de la obra original sin, por ello, tener que ser una simple réplica. En esto consiste la labor del cineasta.

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

Methyl bromide (CH3Br) emitted from plants constitutes a natural source of bromine to the atmosphere, and is a component in the currently unbalanced global CH3Br budget. In the stratosphere, CH3Br contributes to ozone loss processes. Studies of stable isotope composition may reduce uncertainties in the atmospheric CH3Br budget, but require well-constrained isotope fingerprints of the source end members. Here we report the first measurements of stable bromine isotopes (δ81Br) in CH3Br from abiotic plant emissions. Incubations of both KBr-fortified pectin, a ubiquitous cell-stabilizing macromolecule, and of a natural halophyte (Salicornia fruticosa), yielded an enrichment factor (ε) of -2.00 ± 0.23‰ (1σ, n = 8) for pectin and -1.82 ± 0.02‰ (1σ, n = 4) for Salicornia (the relative amount of the heavier 81Br was decreased in CH3Br compared to the substrate salt). For short incubations, and up to 10% consumption of the salt substrate, this isotope effect was similar for temperatures from 30 up to 300 °C. For longer incubations of up to 90 h at 180 °C the δ81Br values increased from -2‰ to 0‰ for pectin and to -1‰ for Salicornia. These δ81Br source signatures of CH3Br formation from plant matter combine with similar data for carbon isotopes to facilitate multidimensional isotope diagnostics of the CH3Br budget.

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

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.

Manduca sexta recognition and resistance among allopolyploid Nicotiana host plants

Lou, Yonggen; Baldwin, Ian T.

2003-01-01

Allopolyploid speciation occurs instantly when the genomes of different species combine to produce self-fertile offspring and has played a central role in the evolution of higher plants, but its consequences for adaptive responses are unknown. We compare herbivore-recognition and -resistance responses of the diploid species and putative ancestral parent Nicotiana attenuata with those of the two derived allopolyploid species Nicotiana clevelandii and Nicotiana bigelovii. Manduca sexta larvae attack all three species, and in N. attenuata attack is recognized when larval oral secretions are introduced to wounds during feeding, resulting in a jasmonate burst, a systemic amplification of trypsin inhibitor accumulation, and a release of volatile organic compounds, which function as a coordinated defense response that slows caterpillar growth and increases the probability of their being attacked. Most aspects of this recognition response are retained with modifications in one allotetraploid (N. bigelovii) but lost in the other (N. clevelandii). Differences between diploid and tetraploid species were apparent in delays (maximum 1 and 0.5 h, respectively) in the jasmonate burst, the elicitation of trypsin inhibitors and release of volatile organic compounds, and the constitutive levels of nicotine, trypsin inhibitors, diterpene glycosides, rutin, and caffeoylputrescine in the leaves. Resistance to M. sexta larvae attack was most strongly associated with diterpene glycosides, which were higher in the diploid than in the two allotetraploid species. Because M. sexta elicitors differentially regulate a large proportion of the N. attenuata transcriptome, we propose that these species are suited for the study of the evolution of adaptive responses requiring trans-activation mechanisms.

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.

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

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.

Higher notification rates of sexually transmissible infections (STIs) are reported among Aboriginal and Torres Strait Islander (Aboriginal) compared with non-Aboriginal people in Australia. The aim of this study is to estimate the pooled prevalence of chlamydia, gonorrhoea, syphilis and trichomonas among Aboriginal people in Australia by sex, age-group, setting (clinic vs population/community-based) and population group [adults, pregnant females, young people (12-29 years) and prisoners]. The databases Medline, PubMed and Web of Science were searched in May 2015. A meta-analysis was conducted to estimate the pooled prevalence of the four STIs in Aboriginal people and if possible, by gender, age-group, setting and population group. A total of 46 studies were included. The pooled prevalence was 11.2% (95%CI: 9.4-13.0%) for chlamydia (36 studies), 12.5% (95%CI: 10.5-14.6%) for gonorrhoea (28 studies), 16.8% (95%CI: 11.0-22.6%) for syphilis (13 studies) and 22.6% (95%CI: 18.5-26.7%) for trichomonas (11 studies); however, there was significant heterogeneity between studies (I(2) Aboriginal people through community-based programs that target asymptomatic young people.

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

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

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

Originality/gap/relevance/implications: 1. the Ivory Tower demonstrates the existence of a gap in the relation between theory and practice; 2. the essay is conducted according to critical approaches; 3. the Critical Theory has the potential to deconstruct the assigned and socially constructed meanings of the Ivory Tower. Key methodological aspects: This is a theoretical essay that dialectically explores the Ivory Tower metaphor. Summary of key results: 1. the organizational science linked to the instrumental logic makes no place for praxis; 2. the Traditional Theory does not allow thinking about the relation between theory and practice through praxis, because it polarizes such categories and gives primacy to practice by demanding performance and productivity from theory; 3. based on the Ivory Tower metaphor, it is necessary to make criticisms for the sake of praxis and not for the sake of the practice understood just as technical and instrumental utility.

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

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 Four cytoplasmic male sterile (cms F1flue-cured hybrids cv. Wiaelica × cv. Virginia Golta (VG, the male fertile analogue and the parental varieties were tested at two locations in Poland in a replicated field trial. The cms sources in the hybrids wereN. suaveolens,N. amplexicaulis,N. bigeloviiand aN. tabacumcms mutant. Under the slight to moderate pressure from black root rot present at the trial sites the hybrids showed a moderate tolerance of the disease characteristic of VG as opposed to medium strong susceptibility of Wislica. Apart from the effect of black root rot tolerance the vegetative vigor of the hybrids (plant height, leaf size, earliness was affected by cytoplasm source. The F1hybrid withN. suaveolens cytoplasm flowered approximately three days later than the remaining hybrids. Of the cms hybrids tested cmsN. bigelovii produced the tallest plants with largest mid-position leaves. Yields of cured leaves were largely influenced by black root rot and were generally higher in VG and in the hybrids than in Wislica. Leaf yields and curability were generally little affected by cms source under low pressure from black root rot. At the site with a relatively high level of black root rot infestation the yields of cmsN. suaveolens were slightly lower but the percentage of light grades slightly higher compared to those of other cms hybrids. CmsN. suaveolens was the best hybrid in terms of money returns at the low black root rot field but it was the poorest hybrid performer under high pressure from the disease. Contents of nitrogen, sugars, nicotine and ash was little affected by source of cms. There was an increased incidence of potato virus Y (PVY and white spots in cmsN. suaveolens and, to a lesser extent, in cmsN. bigelovii as compared to the remaining disease-free entries.

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

CO 2 -exchange, diurnal changes in malate- and ion concentrations of the halophytes Carpobrotus edulis, Crithmum maritimum, Mesembryanthemum nodiflorum, Salicornia fruticosa, Suaeda maritima, and Trifolium fragiferum were investigated after culture at different NaCl concentrations. In Carp. edulis and Mes. nodiflorum the diurnal rhythm of CO 2 -exchange is in accordance with that of crassulacean acid metabolism (CAM), in Sal. fruticosa, Crithm. maritimum, Suaeda maritima, and Trif. fragiferum with that of Benson-Calvin metabolism (C 3 ). Malate concentration and CO 2 uptake in the sap latter group are not influenced. On the other hand, Carp. edulis and Mes. nodiflorum show an accumulation of malate during the night, which can be interpreted as a further indication of CAM.The two species most resistant to NaCl, Carp. edulis and Sal. fruticosa, greatly differ very much in their NaCl content. NaCl concentration in Salicornia is four times higher than in Carpobrotus.The different metabolic properties studied might be of ecological importance for the plants in their natural habitats. The effect of NaCl on metabolic processes is discussed.

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

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.

One problem in designing bioregenerative life support systems (BLSS) is developing technolo-gies to include human liquid and solid waste in intrasystem recycling. A specific task is recycling of NaCl excreted in urine by humans. We showed recently that this could be achieved through inclusion of the salt accumulating halophyte Salicornia europaea in the autotrophic compart-ment of the BLSS (Balnokin et al., ASR, 2010, in press). A model of NaCl circulation in BLSS with inclusion of S. europaea was based on the NaCl turnover in the human -urine -nutrient solution -S. europaea -human cycle. Mineralized urine was used as a basis for preparation of a nutrient solution for the halophyte cultivation. The shoots of the halophyte cultivated in the mineralized urine and containing NaCl could to be used by the BLSS inhabitants in their diets. In this report we describe cultivation of S. europaea which allows turnover of NaCl and produces daily shoot biomass containing Na+ and Cl- in quantities approximately equal to those excreted in daily human urine. The plants were grown in water culture in a climatic chamber under controlled conditions. A solution simulating mineralized urine (SSMU) was used as a basis for preparation of a nutri-ent solution for S. europaea cultivation. For continuous biomass production, seedlings of S. europaea, germinated preliminary in moist sand, were being transferred to the nutrient solu-tion at regular intervals (every two days). Duration of the conveyor operation was 112 days. During the first 56 days, the seedlings were being planted in SSMU diluted by a factor of 1.5 (2/3 SSMU). The same solution was introduced into the growth vessels as volumes of growth medium decreased due to plant transpiration. Starting from the 56th day as conveyor operation was initiated, the plants were being harvested every two days; the solutions from the discharged vessels were mixed with the fresh SSMU and the mixture was introduced into all other growth vessels of

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

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

2016-03-01

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

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

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

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

Petrological constraints on the recycling of mafic crystal mushes, magma ascent and intrusion of braided sills in the Torres del Paine mafic complex (Patagonia)

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

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 We investigate the survivorship, growth and diet preferences of hatchery-raised juvenile urchins, Tripneustes gratilla, to evaluate the efficacy of their use as biocontrol agents in the efforts to reduce alien invasive algae. In flow-through tanks, we measured urchin growth rates, feeding rates and feeding preferences among diets of the most common invasive algae found in Kāneʻohe Bay, Hawaiʻi: Acanthophora spicifera, Gracilaria salicornia, Eucheuma denticulatum and Kappaphycus clade B. Post-transport survivorship of outplanted urchins was measured in paired open and closed cages in three different reef environments (lagoon, reef flat and reef slope for a month. Survivorship in closed cages was highest on the reef flat (∼75%, and intermediate in the lagoon and reef slope (∼50%. In contrast, open cages showed similar survivorship on the reef flat and in the lagoon, but only 20% of juvenile urchins survived in open cages placed on the reef slope. Urchins grew significantly faster on diets of G. salicornia (1.58 mm/week ± 0.14 SE and Kappaphycus clade B (1.69 ± 0.14 mm/wk than on E. denticulatum (0.97 ± 0.14 mm/wk, with intermediate growth when fed on A. spicifera (1.23 ± 0.11 mm/wk. Interestingly, urchins display size-specific feeding preferences. In non-choice feeding trials, small urchins (17.5–22.5 mm test diameter consumed G. salicornia fastest (6.08 g/day ± 0.19 SE, with A. spicifera (4.25 ± 0.02 g/day and Kappaphycus clade B (3.83 ± 0.02 g/day intermediate, and E. denticulatum was clearly the least consumed (2.32 ± 0.37 g/day. Medium-sized (29.8–43.8 mm urchins likewise preferentially consumed G. salicornia (12.60 ± 0.08 g/day, with less clear differences among the other species in which E. denticulatum was still consumed least (9.35 ± 0.90 g/day. In contrast, large urchins (45.0–65.0 mm showed no significant preferences among the different algae species at all (12.43–15.24 g/day. Overall consumption rates in non

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

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

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

Tritium-caused background currents in electron multipliers

Malinowski, M.E.

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 Reserva Natural do Sapal de Castro Marim e Vila Real de Santo António (RNSCMVRSA is a natural reserve (SE of Portugal, Algarve region that has habitats with different saline conditions and great ecological importance. Halophytes are plants that grow in a wide variety of saline habitats, namely in RNSCMVRSA, and can accumulated in their biomass high contents of salt. This plant behavior can increase production of reactive oxygen species (ROS and consequently, the oxidative stress, cellular damage and metabolic disorders. In order to protect the cells from ROS, these plants developed an efficient antioxidant system. This system can be constituted by phenolics compounds that have an important effect on oxidative, anti-inflammatory and microbial stability important properties for food, dietary and pharmaceutical industries. Therefore, this work aims to identify the phenolic compounds in biomass of different autochthones halophytes species growing on natural conditions in RNSCMVSRA. Composite samples of Salicornia patula, Salicornia ramosissima, Sarcoccornia fruticosa and Sarcocornia perennis were collected in 2013. Sequential extraction was realized: firstly the plant samples were subjected to soxhlet extraction using dichloromethane and then by a solid-liquid extraction with ethanol. Finally, the main compounds present in each extract were identified by GC-MS (Gas chromatography–mass spectrometry. The total of phenolic compounds and polyphenolic antioxidants in the extracts was also determined by Folin-Ciocalteu method.

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

With the purpose of reducing the heat in the interior of the Tower of the Angel, building of offices located in avenida Paseo de la Reforma of Mexico City, a renovation was carried out that included the installation of an insulating crystal cover in all the building. Also, it was opted for an environmental system of air-cooling to fulfill the functions of the HVAC (Heating, Ventilation and Air Conditioning), systems. It is possible to indicate that, in addition to the energy saving, the applied technology allowed to transform an old and uncomfortable construction into a construction of worldwide class, able to compete with new works of the city and harmonize with present environmental and aesthetic requirements.

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

Maria di Ciciliano Formation crop out near Montecastrilli (Terni, in the southwestern branch of the Tiberino Basin.  Many specimens of plants ("mummified" woods, fruits and seeds, freshwater molluscs, ostracods, vertebrate bones and coprolites were collected at Torre Picchio. 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. Giacomo and Olivola F. U. (Middle and Late Villafranchian, Late Pliocene. Mimomys medasensis, an Iberoccitane element, is signaled for the first time in Italy.  From the geological point of view, the S.

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

2003-01-01

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

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

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

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

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

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

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

Lifecycle analysis is a tool widely used to evaluate the climate impact of greenhouse gas emissions attributable to the production and use of biofuels. In this paper we employ an augmented lifecycle framework that includes climate impacts from changes in surface albedo due to land use change. We consider eleven land-use change scenarios for the cultivation of biomass for middle distillate fuel production, and compare our results to previous estimates of lifecycle greenhouse gas emissions for the same set of land-use change scenarios in terms of CO2e per unit of fuel energy. We find that two of the land-use change scenarios considered demonstrate a warming effect due to changes in surface albedo, compared to conventional fuel, the largest of which is for replacement of desert land with salicornia cultivation. This corresponds to 222 gCO2e/MJ, equivalent to 3890% and 247% of the lifecycle GHG emissions of fuels derived from salicornia and crude oil, respectively. Nine of the land-use change scenarios considered demonstrate a cooling effect, the largest of which is for the replacement of tropical rainforests with soybean cultivation. This corresponds to - 161 gCO2e/MJ, or - 28% and - 178% of the lifecycle greenhouse gas emissions of fuels derived from soybean and crude oil, respectively. These results indicate that changes in surface albedo have the potential to dominate the climate impact of biofuels, and we conclude that accounting for changes in surface albedo is necessary for a complete assessment of the aggregate climate impacts of biofuel production and use.

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

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.

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

Relative rate study of the kinetics, mechanism, and thermodynamics of the reaction of chlorine atoms with CF3CF═CH2 (HFO-1234yf) in 650-950 Torr of N2 or N2/O2 diluent at 296-462 K.

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.

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

A vacuum system consisting of a 40 m long 8.8 cm diameter stainless steel tube, pumped by 7 pumping stations, has been assembled using automatic welding methods. All components have been fired at 950 0 C in a vacuum furnace at a pressure -4 Torr. Each pumping station contains a Ti-sublimator, a 30 liter/s ion pump and an UHV gauge. After assembly, the entire system was baked out at 250 0 C for 24 hours. A pressure -11 Torr was reached after titanium flash. Surface treatment of stainless for 10 -11 Torr operation, bake out and conditioning cycle to read 1 x 10 -11 Torr, and leak checking at low pressures are discussed

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.

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

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

Directory of Open Access Journals (Sweden)

Yuan Yao

2016-12-01

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

Lifecycle analysis is a tool widely used to evaluate the climate impact of greenhouse gas emissions attributable to the production and use of biofuels. In this paper we employ an augmented lifecycle framework that includes climate impacts from changes in surface albedo due to land use change. We consider eleven land-use change scenarios for the cultivation of biomass for middle distillate fuel production, and compare our results to previous estimates of lifecycle greenhouse gas emissions for the same set of land-use change scenarios in terms of CO 2 e per unit of fuel energy. We find that two of the land-use change scenarios considered demonstrate a warming effect due to changes in surface albedo, compared to conventional fuel, the largest of which is for replacement of desert land with salicornia cultivation. This corresponds to 222 gCO 2 e/MJ, equivalent to 3890% and 247% of the lifecycle GHG emissions of fuels derived from salicornia and crude oil, respectively. Nine of the land-use change scenarios considered demonstrate a cooling effect, the largest of which is for the replacement of tropical rainforests with soybean cultivation. This corresponds to − 161 gCO 2 e/MJ, or − 28% and − 178% of the lifecycle greenhouse gas emissions of fuels derived from soybean and crude oil, respectively. These results indicate that changes in surface albedo have the potential to dominate the climate impact of biofuels, and we conclude that accounting for changes in surface albedo is necessary for a complete assessment of the aggregate climate impacts of biofuel production and use.

Mexico joins the venture: Joint Implementation and Greenhouse Gas Emissions

Energy Technology Data Exchange (ETDEWEB)

Imaz, M.; Gay, C.; Friedmann, R.; Goldberg, B.

1998-11-01

Joint Implementation (JI) and its pilot phase of Activities Implemented Jointly (AIJ) are envisioned as an economic way of reducing global emissions of greenhouse gases. This paper draws upon the Mexican experience with AIJ to identify Mexican concerns with AIJ/JI and proposed solutions to these. Three approved Mexican AIJ projects (Ilumex, Scolel Te, and Salicornia) are described in detail. The Ilurnex project promotes the use of compact fluorescent lamps in Mexican homes of the States of Jalisco and Nuevo Leon, to reduce electric demand. Scolel Te is a sustainable forest management project in Chiapas. Salicornia examines the potential for carbon sequestration with a Halophyte-based crop irrigated with saline waters in Sonora. These three projects are reviewed to clarify the issues and concerns that Mexico has with AIJ and JI and propose measures to deal with them. These initial Mexican AIJ projects show that there is a need for creation of standard project evaluation procedures, and criteria and institutions to oversee project design, selection, and implementation. Further JI development will be facilitated by national and international clarification of key issues such as additionality criteria, carbon-credit sharing, and valuation of non-GHG environmental and/or social benefits and impacts for AIJ projects. Mexico is concerned that JI funding could negatively impact official development assistance or that OECD countries will use JI to avoid taking significant GHG mitigation actions in their own countries. The lack of carbon credit trading in the AIJ stage must be removed to provide useful experience on how to share carbon credits. National or international guidelines are needed to ensure that a portion of the carbon credits is allocated to Mexico.

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

1975-01-01

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

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

Comprehensive study on the pressure dependence of shock wave plasma generation under TEA CO2 laser bombardment on metal sample

2001-01-01

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

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.

Effects of low-pressure air on oxygen contamination and lithium corrosion of a tantalum alloy, T-111, at 980 and 1260 C

Gahn, R. F.

1974-01-01

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

Very high-current propagation in the ion-focused to collision-dominated regime

International Nuclear Information System (INIS)

Sanford, T.W.L.; Welch, D.R.; Mock, R.C.

1994-01-01

Measurements and analysis show that the 13 TW, Hermes-III [J. J. Ramirez et al., Digest of Technical Papers, 6th IEEE Pulsed Power Conference (Institute of Electrical and Electronic Engineers, New York, 1987), p. 294], pulsed, electron beam has two windows of stable transport in long drift cells filled with N 2 gas terminated by a bremsstrahlung producing target: a low-pressure window (between ∼1 and ∼100 mTorr) that is dominated by propagation in the semicollisionless ion-focused regime (IFR), and a high-pressure window (between ∼1 and ∼100 Torr) that is dominated by propagation in the resistive collisional regime. In the transition region between the two windows, beam plasma--electron instabilities significantly disrupt propagation. Propagation in both regimes (the IFR at early time and the collisional at later time) is observed from ∼5 to ∼100 mTorr, which produces two distinct bremsstrahlung pulses from the single injected beam pulse. As the pressure increases, two-stream instabilities terminate IFR propagation and the associated bremsstrahlung pulse earlier and earlier in time. Above 5 mTorr, the instability is sufficiently quenched by gas collisions that propagation in the collisional regime back in the beam body occurs, leading to a second propagation and associated bremsstrahlung pulse. Above 200 mTorr, the gas breaks down too rapidly for a significant IFR pulse to form, and for higher pressures only a single pulse in the collisional regime is propagated. Reasonable stability in the collisional regime is not achieved until pressures exceed 1 Torr

Salt marsh recovery from a crude oil spill: Vegetation, oil weathering, and response

Hoff, R.Z.; Shigenaka, G.; Henry, C.B. Jr.

1993-01-01

When a spill of Prudhoe Bay crude oil covered a fringing Salicornia virginica marsh in Fidalgo Bay, Washington (northern Puget Sound) in February 1991, response personnel used several low-impact techniques to remove oil from the marsh, and minimized access by cleanup workers. Following the response, a monitoring program was established to track marsh recovery, and to document the effectiveness of the response techniques used and their impacts on the marsh. Through monthly sampling over a 16-month period, vegetative growth was monitored and chemical degradation of remaining oil was tracked. Sampling was conducted along transects located in four areas affected in different ways by the spill, including an oiled, trampled section; an oiled, vacuumed section; and an oiled, washed, and vacuumed section. In addition, a control transect was established in an unoiled adjacent marsh. The study included both biological and chemical components. Biological measurements included percent cover of live vegetation (sampled monthly) and below-ground plant biomass (sampled at the beginning of each growing season in April 1991 and April 1992). Sediment samples included surface sediment (monthly) and core samples collected at the beginning and end of the growing seasons. Sediment samples were analyzed using gas chromatography/mass spectroscopy, and indicator compounds were tracked to determine rates of oil degradation. Results from 16 months of post-spill monitoring show that foot trampling was most detrimental to marsh plants, while washing with vacuuming removed the most oil and minimized adverse impacts to vegetation. Dense clay substrate helped prevent oil from penetrating the sediment, thus minimizing acute toxic effects from oil exposure to marsh plant rootstock. By the second growing season post-spill, Salicornia and other marsh plants were growing in all areas except one heavily oiled patch

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

Microwave cavity techniques were used to measure electron density in a spherical, inertial-electrostatic confinement device using six ion guns. The density was roughly proportional to ion current (1 to 17 mA) and decreased somewhat with increasing ion energy (10 to 37 keV). With D 2 pressure decrease from 10 to 3 mTorr, n/sub e/ decreased faster than linearly and below approximately 3 mTorr decreased linearly with pressure down to the lowest pressure of 0.4 mTorr. At 1 mTorr and 10 mA, measurements (with poor spatial resolution) were consistent with 10 10 total electrons and a central n/sub e/ of 10 9 electrons/cm 3 . Neutron flux (at 50 keV) was about one sixth that of Hirsch (J. Appl. Phys. 38, 4522 (1967)). Six- vs. three-gun operation showed a small enhancement of both n/sub e/ and neutron flux that may indicate some particle trapping

Swimming performance, venous oxygen tension and cardiac performance of coronary-ligated rainbow trout, Oncorhynchus mykiss, exposed to progressive hypoxia

Steffensen, J F; Farrell, A P

1998-01-01

We performed in vivo studies to examine the idea that cardiac work is impaired in rainbow trout (Oncorhynchus mykiss) below a certain venous PO2 threshold. We hypothesized that coronary-ligated fish, swimming continuously at a reasonably high water velocity (1.5 body lengths x s(-1)) and exposed...... to progressive hypoxia, would fatigue at higher venous PO2 and ambient water PO2 compared with sham-operated fish. However, we found that both the lowest venous PO2 that supported hypoxic swimming (9.9 torr for coronary-ligated fish and 11.1 torr for sham-operated fish) and the venous PO2 at fatigue (7.8 torr...... and 8.6 torr, respectively) were the same for coronary-ligated and sham-operated fish. Also, both groups quit swimming at the same water PO2 heart rate and hematocrit. Nevertheless, significant differences in cardiac performance did exist between the two groups. Whereas ventral aortic blood pressure...

2017-09-01

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

The V ..-->.. T, R relaxation rate for NH/sub 3/ (..nu../sub 2/) was studied from 198/sup 0/K to 398/sup 0/K by the method of laser-excited vibrational fluorescence. The self-deactivation rate constant decreases from 2.4 ..mu..sec torr/sup -1/ at 198/sup 0/K to 0.65 ..mu..sec/sup -1/ torr/sup -1/ at 398/sup 0/K. The rate constants for deactivation by He, Ar, N/sub 2/, and O/sub 2/ are much smaller and show a weak temperature dependence in the opposite direction. The vibrational relaxation rates of the coupled ..nu../sub 1/, ..nu../sub 3/ stretching level manifold and of the 2..nu../sub 2/ bending level in H/sub 2//sup 18/O was studied from 250/sup 0/K to 400/sup 0/K using th same method as for NH/sub 3/. The ..nu../sub 1/, ..nu../sub 3/ self-deactivation rate goes from 1.4 ..mu..sec/sup -1/ torr/sup -1/ at 250/sup 0/K to 0.48 ..mu..sec-/sup 1/ torr-/sup 1/ at 400/sup 0/K. For 2..nu../sub 2/ it goes from 4.5 ..mu..sec-/sup 1/ torr to 1.9 ..mu..sec/sup -1/ torr/sup -1/. The temperature dependence of the deactivation of both levels by He and Ar is much weaker and the rates are several hundred times slower. Deactivation of ..nu../sub 1/, ..nu../sub 3/ by N/sub 2/, O/sub 2/, and CO/sub 2/ is measured only at 293/sup 0/K. N/sub 2/ and O/sub 2/ deactivate ..nu../sub 1/, ..nu../sub 3/ about 5 and CO/sub 2/ about 50 times faster than He or Ar.

Oxidation of T-111 alloy at high temperatures and low pressures

International Nuclear Information System (INIS)

Mitchell, R.J.

1976-01-01

T-111 was oxidized at 850, 900, 950 and 1000 0 C at pressures of 3 x 10 -4 , 1 x 10 -4 , and 5 x 10 -5 torr. For oxygen intake up to 3500 ppM, fine ( 0 C produces incoherent particles of HfO 2 oriented with respect to the matrix. Beyond 3500 ppM, oxygen is dissolved in the Ta--W matrix. In the TEM, a tweed structure of coherent plates with (210)/sub T-111/ habit planes is first seen at 6000 ppM. Further oxidation produces β-Ta 2 O 5 in patches at platelets. Volume expansion during the formation of β-Ta 2 O 5 at platelets initiates transgranular cleavage along the platelet habit planes, which opens new metal surfaces to oxygen and accelerates the rate of oxygen gain after 6000 ppM. The progression from tweed structure to subplatelets to platelets suggests nucleation and growth. Dense nucleation and short platelets are observed at 3 x 10 -4 torr. Long platelets are observed at 1 x 10 -4 torr and 5 x 10 -4 torr. At 900 0 C and above, thick surface oxides develop at 3 x 10 -4 torr but not at lower pressures. Oxidations at 850 0 C develop thick surface oxides at 5 x 10 -5 torr but not at the higher pressures. A new unit cell for β-Ta 2 O 5 is proposed: monoclinic with a = 6.22 A, b = 3.88 A, c = 6.22 A and β = 118.75 0 . Electron diffraction at platelets and on the surface shows that other reported unit cells are incorrect. Rate of oxygen intake exceeds 2000 ppM per hour and accelerates after a weight of 6000 ppM is reached and platelets appear

A Mars hopper has been proposed as a Mars mobility concept that will also demonstrate and advance in-situ resource utilization. The components needed in a Mars propellant production plant have been developed to various levels of technology maturity, but there is little experience with the systems in a Mars environment. Two systems for the acquisition and compression of the thin carbon dioxide atmosphere were designed, assembled, and tested in a Mars environment chamber. A microchannel sorption pump system was able to raise the pressure from 7 Torr to 450 Torr or from 12 Torr to over 700 Torr in two stages. This data now provides information needed to make additional improvements in the sorption pump technology to increase performance, although a system-level analysis might prove that some amount of pre- or post-compression may be a preferred solution. A mini cryofreezer system was also evaluated as an alternative method for carbon dioxide acquisition and compression. Finally, an electrolysis system was tested and successfully demonstrated start-up operation and thermal stability of all components during long-term operation in the chamber.

Helium pumping on argon frost has been investigated on Tokamak Fusion Test Reactor (TFTR) neutral beam injectors and shown to be viable for limited helium beam operation. Maximum pumping speeds are ∼25% less than those measured for pumping of deuterium. Helium pumping efficiency is low, >20 argon atoms are required to pump each helium atom. Adsorption isotherms are exponential and exhibit a twofold increase in adsorption capacity as the cryopanel temperature is reduced from 4.3 K to 3.7 K. Pumping speed was found to be independent of cryopanel temperature over the temperature range studied. After pumping a total of 2000 Torr l of helium, the beamline base pressure rose to 2x10 -5 Torr from an initial value of 10 -8 Torr. Accompanying this three order of magnitude increase in pressure was a modest 40% decrease in pumping speed. The introduction of 168 Torr l of deuterium prior to helium injection reduced the pumping speed by a factor of two with no decrease in adsorption capacity

This paper reviews the transport of the 19-MeV, 700-kA, 25-ns Hermes-III electron beam in long gas cells filled with N 2 gas spanning six decades in pressure from 10 3 to ∼10 3 Torr. We show through measurements and theoretical analyses that the beam has two windows 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). In the CDR, 79±1.5% of the beam energy is transported over 11 m at 20 Torr. In the IFR, we show that intense radiation fields with controllable rise times and pulse widths can be generated on axis at a bremsstrahlung target. In summary, the measurements and analyses presented here provide a quantitative description of the Hermes-III beam transport over six decades in pressure

Sudiyanto; Prajitno

2002-01-01

The Acquisition and Control design for vacuum unit of an Electron Beam Machine using Remote manual, Software and Hardwire have been done. For Remote Manual system open/close of pneumatic valves can be done by using 220 Vac/12 Vdc relay equipped with long cable and switches on the control panel. An indicator lamp mentioning ready/not ready status of the vacuum unit would be the main indicator in making decisions to open/close the pneumatic valves. On the software method the acquisition and controlled would be done by using the Distributed Control System which have already been developed recently. The references voltage on he vacuum level of 10 -2 Torr and 10 -6 Torr would be proceeded by using ADC techniques of PCL-718 and recorded on the software system as a references data base in making an open/closed pneumatic decision. On the Hardwire method, on/off controlling of the pneumatic valves could be done by using voltage comparison by using logic circuitry where the vacuum references level of 10 -2 Torr and 10 -6 Torr have already been taken, monitored by penning gauge. The hardwire method is the fastest in response time than the others. (author)

Simulation and modeling of the Gamble II self-pinched ion beam transport experiment

Rose, D.V.; Ottinger, P.F.; Hinshelwood, D.D.

1999-01-01

Progress in numerical simulations and modeling of the self-pinched ion beam transport experiment at the Naval Research Laboratory (NRL) is reviewed. In the experiment, a 1.2-MeV, 100-kA proton beam enters a 1-m long, transport region filled with a low pressure gas (30--250 mTorr helium, or 1 Torr air). The time-dependent velocity distribution function of the injected ion beam is determined from an orbit code that uses a pinch-reflex ion diode model and the measured voltage and current from this diode on the Gamble II generator at NRL. This distribution function is used as the beam input condition for numerical simulations carried out using the hybrid particle-in-cell code IPROP. Results of the simulations will be described, and detailed comparisons will be made with various measurements, including line-integrated electron-density, proton-fluence, and beam radial-profile measurements. As observed in the experiment, the simulations show evidence of self-pinching for helium pressures between 35 and 80 mTorr. Simulations and measurements in 1 Torr air show ballistic transport. The relevance of these results to ion-driven inertial confinement fusion will be discussed

Hydrogen discharge cleaning of the PLT vacuum vessel has been studied by mass spectroscopy of desorbed gases and surface analysis of exposed samples. Several modes of vessel conditioning have been studied to date: (1) a high power discharge cleaning (PDC) mode, with a peak power density to the vessel wall P/sub s/ approximately 0.6 w/cm 2 and a peak electron temperature T/sub e/ approximately 100 ev; (2) low power (Taylor-type) discharge cleaning (TDC) with P/sub s/ approximately 0.05 w/cm 2 and T/sub e/ equal to or less than 5 eV. The predominant residual gases produced during PDC are CH 4 (1-5 x 10 -6 torr) and CO (1-10 x 10 -7 torr), whereas TDC produced primarily H 2 O (1-2 x 10 -6 torr) and CH 4 (1-10 x 10 -7 torr). In situ surface analysis of hydrocarbon-covered stainless steel has shown significant decreases in carbon coverage occurring after 10 3 -10 4 pulses of either cleaning mode. Observed changes in oxygen coverage are more difficult to interpret because of the presence of the nascent oxide layer on the stainless steel substrates

The CBA (Colliding Beam Accelerator, formerly known as ISABELLE) Full Cell Magnet System consisting of six superconducting dipole magnets and two superconducting quadrupole magnets requires two separate vacuum systems. One, known as beam vacuum operates below 3 x 10 -11 Torr and the other, known as insulating vacuum, operates at less than 10 -7 Torr to isolate cryo circuits from atmosphere and from the uhv beam tubes. The uhv bore tube is isolated from the 4.0 0 K magnet by thirty-six (36) layers of superinsulation and insulating vacuum. Heat load measurements on the bore tube have been completed and found to agree with data obtained in smaller controlled experiments. Measurements of helium, accumulated on cryogenic pumped charcoal panels over many weeks, have verified sensitive helium mass spectrometer leak detection methods for vacuum integrity, providing sound design of the welded complex. The Full Cell was assembled and operated under conditions that would exist in the completed machine. Pressures below 2 x 10 -11 Torr beam vacuum requirement and below 2 x 10 -7 Torr insulating vacuum, were routinely achieved during all phases of the Full Cell operation and support systems testing

Since the installation of PF-DENA at AEOI about one year ago, we performed quantitative studies of variation of X-ray radiations from a new Filippov-type plasma focus device: Dena (90 kJ, 25 kV, 288 μF). The operating gas was neon at a constant pressure of 1 torr and different pressures of krypton admixture (up to 0.3 torr), with the discharge voltage up to 18 kV. For charging voltage of 17 kV with 41 kJ stored energy and spark gap pressure of 1.2x 10 -2 torr, the maximum soft and little hard X-ray (SXR-HXR) emission is found for the neon, resulting in a total SXR yield of 2 V/shot measured by silicon semiconductor diode detectors. Concerning the effect of krypton admixture, a maximum intensity of SXR radiation has been observed at low krypton pressure that is about 1 V/shot. At higher pressure, the quality of SXR emission decreases down to zero. However, the maximum intensity of the HXR radiation yield in the same pressure range was found to be 2.5 V/shot. By increasing the pressure of krypton up tp 0.3 torr, the results show that the krypton admixture gas generally causes, a decrease of the SXR radiation yield down to zero, whereas, the HXR emission yield carries a maximum value at the optimum pressure of krypton that is about 0.1 torr. Nevertheless, the pressure increments of krypton lead to decreasing in the discharge voltage for the maximum X-ray production. (author)

To investigate the effect of hyperventilation on cerebral oxygenation after severe head injury. A prospective, observational study. Neurointensive care unit at a university hospital. A total of 90 patients with severe head injury (Glasgow Coma Scale score brain tissue oxygen pressure (PbrO2) was performed as a measure of cerebral oxygenation. Arterial PCO2 was decreased each day over a 5-day period for 15 mins by increasing minute volume on the ventilator setting to 20% above baseline. Arterial blood gas analysis was performed before and after changing ventilator settings. Multimodality monitoring, including PbrO2, was performed in all patients. Absolute and relative PbrO2/PaCO2 reactivity was calculated. Outcome at 6 months was evaluated according to the Glasgow Outcome Scale. Effective hyperventilation, defined by a decrease of PaCO2 > or =2 torr (0.27 kPa), was obtained in 218 (84%) of 272 tests performed. Baseline PaCO2 averaged 32.3 +/- 4.5 torr (4.31 +/- 0.60 kPa). Average reduction in PaCO2 was 3.8 +/- 1.7 torr (0.51 +/- 0.23 kPa). PbrO2 decreased by 2.8 +/- 3.7 torr (0.37 +/- 0.49 kPa; p < .001) from a baseline value of 26.5 +/- 11.6 torr (3.53 +/- 1.55 kPa). PbrO2/PaCO2 reactivity was low on day 1 (0.8 +/- 2.3 torr [0.11 +/- 0.31 kPa]), increasing on subsequent days to 6.1 +/- 4.4 torr (0.81 +/- 0.59 kPa) on day 5. PbrO2/PaCO2 reactivity on days 1 and 2 was not related to outcome. In later phases in patients with unfavorable outcome, relative reactivity was increased more markedly, reaching statistical significance on day 5. Increased hyperventilation causes a significant reduction in PbrO2, providing further evidence for possible increased risk of secondary ischemic damage during hyperventilation. The low PbrO2/PaCO2 reactivity on day 1 indicates the decreased responsiveness of cerebral microvascular vessels to PaCO2 changes, caused by generalized vascular narrowing. The increasing PbrO2/PaCO2 reactivity from days 2 to 5 suggests that the risk of

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

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

This research studied the use of constructed wetlands (CWs) to reduce water salinity. For this purpose, three halophytic species of the Chenopodiaceae family (Salicornia europaea, Salsola crassa, and Bienertia cycloptera) that are resistant to saline conditions were planted in the CWs, and experiments were conducted at three different salinity levels [electrical conductivity (EC)∼2, 6, 10 dS/m]. EC and concentrations of calcium (Ca), magnesium (Mg), sodium (Na), and chlorine (Cl) were measured before and after phytoremediation with a retention time of 1 week. The results suggested that these plants were able to grow well and complete their life cycles at all the salinity levels within this study. Moreover, these plants reduced the measured parameters to acceptable levels. Therefore, these plants can be considered good options for salt phytoremediation.

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

Surface magnetic field strengths: New tests of magnetoconvective models of M dwarfs

2014-01-01

Precision modeling of M dwarfs has become worthwhile in recent years due to the increasingly precise values of masses and radii which can be obtained from eclipsing binary studies. In a recent paper, Torres has identified four prime M dwarf pairs with the most precise empirical determinations of masses and radii. The measured radii are consistently larger than standard stellar models predict by several percent. These four systems potentially provide the most challenging tests of precision evolutionary models of cool dwarfs at the present time. We have previously modeled M dwarfs in the context of a criterion due to Gough and Tayler in which magnetic fields inhibit the onset of convection according to a physics-based prescription. In the present paper, we apply our magnetoconvective approach to the four prime systems in the Torres list. Going a step beyond what we have already modeled in CM Dra (one of the four Torres systems), we note that new constraints on magnetoconvective models of M dwarfs are now available from empirical estimates of magnetic field strengths on the surfaces of these stars. In the present paper, we consider how well our magnetoconvective models succeed when confronted with this new test of surface magnetic field strengths. Among the systems listed by Torres, we find that plausible magnetic models work well for CM Dra, YY Gem, and CU Cnc. (The fourth system in Torres's list does not yet have enough information to warrant magnetic modeling.) Our magnetoconvection models of CM Dra, YY Gem, and CU Cnc yield predictions of the magnetic fluxes on the stellar surface which are consistent with the observed correlation between magnetic flux and X-ray luminosity.

Investigations on afterglows of neon gas discharges

Steenhuysen, L.W.G.

1979-01-01

Experimental and numerical investigations on afterglows of neon gas discharges are described. The investigated pressure range extends from 0.5 torr to 100 torr; the discharge currents lie between about 1 mA and 100 mA. The decay of the 1s atom densities has been determined experimentally as function of the time elapsed in the afterglow. From the measured decay of metastable 1s 5 atom densities at gas pressure 5 atoms as well as the coefficinets of atomic collisional transfer between the 1s 5 and 1s 4 level are determined. To obtain more insight in the mutual influences of the various loss and production processes of 1s atoms and charge carriers in the afterglow a numerical model has been formed. The behaviour of the afterglow radiation intensity has been measured on discharges with a gas pressure of 1, 10, 20, 50 and 100 torr and a discharge current of 22, 24 and 50 mA. From the results the recombination distribution fractions of the 1s levels are determined and the electron densities at the start of the afterglow of 20, 50 and 100 torr discharges. With the help of the selective excitation spectroscopy the coefficients of atomic transfer between the 2p levels have been measured in the afterglow of discharge with a gas pressure of 1, 10, 20, 50 and 100 torr and a discharge current of 22 mA. From these results and the measured intensities of the various spectral lines in the afterglow the partial recombination coefficients for the 2p levels are calculated. (Auth. )

Gokce, Huseyin.

1991-01-01

In this study, the kinetics of the low-pressure chemical vapor deposition (LPCVD) of tungsten by silane reduction of tungsten hexafluoride on Si(100) surfaces was studied. A single-wafer, cold-wall reactor was sued for the experiments. The SiH 4 /WF 6 ratio was 1.0. The pressure and temperature range were 1-10 torr and 137-385 degree C, respectively. Kinetic data were obtained in the absence of mass-transfer effects. The film thicknesses were measured by gravimetry. Scanning electron microscopy (SEM), Auger electron spectroscopy (AES), x-ray diffraction (XRD), and resistivity measurements were used to analyze the W films. For the horizontal substrate position and 4-minute reaction times, the apparent activation energies were determined to be 0.35 eV/atom for 10 torr, 0.17 eV/atom for 3 torr, and 0.08 eV/atom for 1 torr. Lower temperatures and higher pressures produced porous films, while higher temperatures and lower pressures resulted in continuous films with smoother surfaces. As the Si-W interface, a W(110) preferential orientation was observed. As the W films grew thicker, W orientation switched from (110) to (100). Apparent activation energy seems to change with thickness

The authors have experimentally determined the energy spectrum of a deuteron beam in the energy interval 100 KeV ≤ E ≤ 10 MeV, with typical beam current I ≥ 1-2 A. A 5 kJ (15 kV, 49 μF) plasma focus machine is used to generate the ion beam at relatively low pressure 3-4 Torr D/sub 2/ (beam anode) and at higher pressure 6-8 Torr D/sub 2/ (high-neutron-yield mode). The spectrum is obtained from two different methods, i.e. from ion time of flight - by using time delays of Faraday cup signals with respect to hard x-ray signals - and from ion filtering, (mylar filter with different thickness from 2.5 μm up to 500 μm are used to cover the Faraday cup). The Faraday cup is located in a differentially pumed chamber (10/sup -4/ - 10/sup -5/ Torr) which is separated from the plasma focus chamber (8-3 Torr) by a 150 μm diam. pinhole (12.5 μm thick tungsten foil). The pinhole and Faraday cup are positioned on the gun axis at a distance of 15 cm and 25 cm from the end of the anode respectively

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

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

Chaudhary, K. T.; Ali, J.; Yupapin, P. P.

2014-01-01

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

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

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

Full Text Available Abstract Background Australian Aboriginal peoples and Torres Strait Islanders (Indigenous Australians smoke at much higher rates than non-Indigenous people and smoking is an important contributor to increased disease, hospital admissions and deaths in Indigenous Australian populations. Smoking cessation programs in Australia have not had the same impact on Indigenous smokers as on non-Indigenous smokers. This paper describes the protocol for a study that aims to test the efficacy of a locally-tailored, intensive, multidimensional smoking cessation program. Methods/Design This study is a parallel, randomised, controlled trial. Participants are Aboriginal and Torres Strait Islander smokers aged 16 years and over, who are randomly allocated to a 'control' or 'intervention' group in a 2:1 ratio. Those assigned to the 'intervention' group receive smoking cessation counselling at face-to-face visits, weekly for the first four weeks, monthly to six months and two monthly to 12 months. They are also encouraged to attend a monthly smoking cessation support group. The 'control' group receive 'usual care' (i.e. they do not receive the smoking cessation program. Aboriginal researchers deliver the intervention, the goal of which is to help Aboriginal peoples and Torres Strait Islanders quit smoking. Data collection occurs at baseline (when they enrol and at six and 12 months after enrolling. The primary outcome is self-reported smoking cessation with urinary cotinine confirmation at 12 months. Discussion Stopping smoking has been described as the single most important individual change Aboriginal and Torres Strait Islander smokers could make to improve their health. Smoking cessation programs are a major priority in Aboriginal and Torres Strait Islander health and evidence for effective approaches is essential for policy development and resourcing. A range of strategies have been used to encourage Aboriginal peoples and Torres Strait Islanders to quit

Acute changes in tissue CO2 and pH during reperfusion of the ischemic heart may affect ischemia/reperfusion injury. We tested whether gradual vs. acute decreases in CO2 after cardiomyocyte ischemia affect reperfusion oxidants and injury. Comparative laboratory investigation. Institutional laboratory. Embryonic chick cardiomyocytes. Microscope fields of approximately 500 chick cardiomyocytes were monitored throughout 1 hr of simulated ischemia (PO2 of 3-5 torr, PCO2 of 144 torr, pH 6.8), followed by 3 hrs of reperfusion (PO2 of 149 torr, PCO2 of 36 torr, pH 7.4), and compared with cells reperfused with relative hypercarbia (PCO2 of 71 torr, pH 6.8) or hypocarbia (PCO2 of 7 torr, pH 7.9). The measured outcomes included cell viability (via propidium iodide) and oxidant generation (reactive oxygen species via 2',7'-dichlorofluorescin oxidation and nitric oxide [NO] via 4,5-diaminofluorescein diacetate oxidation). Compared with normocarbic reperfusion, hypercarbia significantly reduced cell death from 54.8% +/- 4.0% to 26.3% +/- 2.8% (p < .001), significantly decreased reperfusion reactive oxygen species (p < .05), and increased NO at a later phase of reperfusion (p < .01). The NO synthase inhibitor N-nitro-L-arginine methyl ester (200 microM) reversed this oxidant attenuation (p < .05), NO increase (p < .05), and the cardioprotection conferred by hypercarbic reperfusion (increasing death to 54.3% +/- 6.0% [p < .05]). Conversely, hypocarbic reperfusion increased cell death to 80.4% +/- 4.5% (p < .01). It also increased reactive oxygen species by almost two-fold (p = .052), without affecting the NO level thereafter. Increased reactive oxygen species was attenuated by the mitochondrial complex III inhibitor stigmatellin (20 nM) when given at reperfusion (p < .05). Cell death also decreased from 85.9% +/- 4.5% to 52.2% +/- 6.5% (p < .01). The nicotinamide adenine dinucleotide phosphate oxidase inhibitor apocynin (300 microM) had no effect on reperfusion reactive oxygen

We assessed the effects of cold and submergence on blood oxygen transport in common map turtles (Graptemys geographica). Winter animals were acclimated for 6-7 wk to one of three conditions at 3 degrees C: air breathing (AB-3 degrees C), normoxic submergence (NS-3 degrees C), and hypoxic (PO2=49 Torr) submergence (HS-3 degrees C). NS-3 degrees C turtles exhibited a respiratory alkalosis (pH 8.07; PCO2=7.9 Torr; [lactate]=2.2 mM) relative to AB-3 degrees C animals (pH 7.89; PCO2=13.4 Torr; [lactate]=1.1 mM). HS-3 degrees C animals experienced a profound metabolic acidosis (pH 7.30; PCO2=7.9 Torr; [lactate]=81 mM). NS-3 degrees C turtles exhibited an increased blood O2 capacity; however, isoelectric focusing revealed no seasonal changes in the isohemoglobin (isoHb) profile. Blood O2 affinity was significantly increased by cold acclimation; half-saturation pressures (P50's) for air-breathing turtles at 3 degrees and 22 degrees C were 6.5 and 18.8 Torr, respectively. P50's for winter animals submerged in normoxic and hypoxic water were 5.2 and 6.5 Torr, respectively. CO2 Bohr slopes (Delta logP50/Delta pH) were -0.15, -0.16, and -0.07 for AB-3 degrees C, NS-3 degrees C, and HS-3 degrees C turtles, respectively; the corresponding value for AB-22 degrees C was -0.37. The O2 equilibrium curve (O2EC) shape was similar for AB-3 degrees C and NS-3 degrees C turtles; Hill plot n coefficients ranged from 1.8 to 2.0. The O2EC shape for HS-3 degrees C turtles was anomalous, exhibiting high O2 affinity below P50 and a right-shifted segment above half-saturation. We suggest that increases in Hb-O2 affinity and O2 capacity enhance extrapulmonary O2 uptake by turtles overwintering in normoxic water. The anomalous O2EC shape and reduced CO2 Bohr effect of HS-3 degrees C turtles may also promote some aerobic metabolism in hypoxic water.

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

PO2 Cycling Reduces Diaphragm Fatigue by Attenuating ROS Formation

2014-01-01

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...

A simple closed loop control system has been developed to maintain the gas pressure in thin-window proportional counters during rocket flights. This system permits convenient external control of detector pressure and system flushing rate. The control system is activated at launch with the sealing of a reference volume at the existing system pressure. Inflight control to plus or minus 2 torr at a working pressure of 760 torr has been achieved on six rocket flights.

The chemical nature of copper and copper oxide (Cu{sub 2}O) surfaces in the presence of CO{sub 2} and H{sub 2}O at room temperature was investigated using ambient pressure x-ray photoelectron spectroscopy. The studies reveal that in the presence of 0.1 torr CO{sub 2} several species form on the initially clean Cu, including carbonate CO{sub 3}{sup 2}, CO{sub 2}{sup {delta}-} and C{sup 0}, while no modifications occur on an oxidized surface. The addition of 0.1 ML Zn to the Cu results in the complete conversion of CO{sub 2}{sup {delta}-} to carbonate. In a mixture of 0.1 torr H{sub 2}O and 0.1 torr CO{sub 2}, new species are formed, including hydroxyl, formate and methoxy, with H{sub 2}O providing the hydrogen needed for the formation of hydrogenated species.

Synthesis and characterization of DC magnetron sputtered ZnO thin films under high working pressures

Hezam, M.; Tabet, N.; Mekki, A.

2010-01-01

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

SrRuO3 thin films grown on MgO substrates at different oxygen partial pressures

2013-01-08

A comprehensive study of SrRuO3 thin films growth on (001) MgO substrates by pulsed laser deposition in a wide oxygen pressure range from 10 to 300 mTorr was carried out. The experimental results showed a correlation between the lattice constants, resistivity, and oxygen partial pressures used. Ru deficiency detected only in films deposited at lower oxygen pressures (<50 mTorr), resulted in an elongation of the in-plane and out-of-plane lattice constants and an increase in the film resistivity. When deposited with oxygen partial pressure of 50 mTorr, SrRuO3 films had lattice parameters matching those of bulk SrRuO3 material and exhibited room temperature resistivity of 320 μΩ·cm. The resistivity of SrRuO 3/MgO films decreased with increasing oxygen partial pressure. Copyright © 2013 Materials Research Society.

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

In twenty patients with COPD, the following pulmonary function test values were obtained (mean +- SD): FEV/sub 1.0/ = 1070 +- 490 ml;FEV/sub 1.0/ % = 47.7 +- 8.9 %;PaO/sub 2/ = 65.8 +- 8.4 torr;PaCO/sub 2/ = 39.7 +- 4.4 torr. All patients underwent right heart catheterization and pulmonary arterial mean pressures (PAMP) were obtained. The PAMP value was 20.2 +- 4.1 torr (range 12 - 28), RVEF was 52.2 +- 8.4 % (range 31 - 63) and RVRFR was 25.5 +- 4.7 %100 msec (range 18 - 34). The PAMP negatively correlated with the RVEF (r = -0.69, p < 0.001) and RVRFR (r = -0.82, p < 0.001). In ten healthy male subjects, the RVEF was 56.6 +- 5.1 % (range 50 - 64) and RVRFR was 37.7 +- 3.0 %100 msec (range 33 - 42). The lower limit of normal for the RVEF was regarded as 46.4 % and that of the RVRFR as 31.7 %100 msec;these are the values two standard deviations below the means. Nine of the twenty patients has a PAMP value of more than 20 torr (the sine qua non of cor pulmonale). Five of these nine patients had RVEF values less than 46.4 % and all of them had RVRFR values of less than 31.7 %100 msec. On the other hand, all of the remaining eleven patients (PAMP 20 torr or less) had RVEF values within the normal range, but ten of the eleven had RVRFR values of less than 31.7 %100 msec. Therefore, the RVRFR value, which showed excellent correlation with the PAMP, provided a noninvasive assessment of pulmonary arterial pressure with good sensitivity in detecting elevated pressure. The RVEF value supplemented the RVRFR with good specificity for detection of elevation of pressure;that is, it eliminated false positive results. (J.P.N.)

Catalyzed hydrogenation of nitrogen and ethylene on metal (Fe, Pt) single crystal surfaces and effects of coadsorption: A sum frequency generation vibrational spectroscopy study

Energy Technology Data Exchange (ETDEWEB)

Westerberg, Staffan Per Gustav [Univ. of California, Berkeley, CA (United States)

2004-01-01

High-pressure catalytic reactions and associated processes, such as adsorption have been studied on a molecular level on single crystal surfaces. Sum Frequency Generation (SFG) vibrational spectroscopy together with Auger Electron Spectroscopy (AES), Temperature Programmed Desorption (TPD) and Gas Chromatography (GC) were used to investigate the nature of species on catalytic surfaces and to measure the catalytic reaction rates. Special attention has been directed at studying high-pressure reactions and in particular, ammonia synthesis in order to identify reaction intermediates and the influence of adsorbates on the surface during reaction conditions. The adsorption of gases N₂, H₂, O₂ and NH₃ that play a role in ammonia synthesis have been studied on the Fe(111) crystal surface by sum frequency generation vibrational spectroscopy using an integrated Ultra-High Vacuum (UHV)/high-pressure system. SFG spectra are presented for the dissociation intermediates, NH₂ (~3325 cm^-1) and NH (~3235 cm^-1) under high pressure of ammonia (200 Torr) on the clean Fe(111) surface. Addition of 0.5 Torr of oxygen to 200 Torr of ammonia does not significantly change the bonding of dissociation intermediates to the surface. However, it leads to a phase change of nearly 180° between the resonant and non-resonant second order non-linear susceptibility of the surface, demonstrated by the reversal of the SFG spectral features. Heating the surface in the presence of 200 Torr ammonia and 0.5 Torr oxygen reduces the oxygen coverage, which can be seen from the SFG spectra as another relative phase change of 180°. The reduction of the oxide is also supported by Auger electron spectroscopy. The result suggests that the phase change of the spectral features could serve as a sensitive indicator of the chemical environment of the adsorbates.

Outgassing rate of the copper-plated beam tube for ISABELLE

1981-01-01

The ultrahigh vacuum system of the intersecting storage accelerator, ISABELLE, will consist of two interlaced rings of stainless steel beam tubes with a circumference 2-1/2 miles each. To obtain a good heat conduction during bakeout and to reduce the resistive wall instability during beam operation, a lmm thick copper coating will be electroplated to the outer surface of this 1.5 mm thick beam tube. To minimize the beam loss due to beam-gas collision, the pressure inside the beam tube is required to be 1 x 10 -11 Torr (N 2 equivalent) or less. To achieve this ultrahigh vacuum, the outgassing rate of the 304 LN stainless steel tubes has been reduced to approx. 1 x 10 -13 Torr. l/cm 2 . sec by vacuum firing at 950 0 C for one hour. However, during acid-bath electroplating of copper, significant amount of hydrogen will be reintroduced and trapped in stainless steel which will substantially increase the outgassing rate (to approx. 2 x 10 -12 Torr . l/cm 2 sec). The outgassing characteristics of these copper-plated beam tubes are studied and discussed within the scope of diffusion and energy of activation. Methods to reduce the outgassing rate to an acceptable level (approx. 1 x 10 -13 Torr . l/cm 2 . sec) are also given

1981-01-01

This apparatus is one of the preliminary experiment equipments for the vacuum system of a UVSOR, and the main objective is to obtain the clean vacuum below 10 - 10 Torr. From the viewpoint of manufacture, there is no problem, but all the works from the design through manufacture, assembling and adjustment of the apparatus, to the obtaining of required vacuum were carried out by the authors themselves. The design and its points, and manufacture are described. In order to obtain clean vacuum and maintain it for long period, the surface cleaning of vacuum tanks is very important. Therefore the method of electrolytic polishing was adopted for the purpose, and its effectiveness was examined. After the surface treatment by two methods, the evacuation test was carried out, and the attained pressure was compared. Electrolytic polishing seemed to be effective. As the method of suppressing surface degasification, there is argon bombardment method. It was attempted to improve the pressure attained by baking only further by this method. By baking at 250 deg C for 30 hr only, the final pressure attained was 1.7 x 10 - 10 Torr, and by making argon bombardment twice during baking, it was 0.9 x 10 - 10 Torr, thus slight improvement was obtained. The main objective to obtain vacuum below 10 - 10 Torr was accomplished, but surface treatment requires more experience. (Kako, I.)

To estimate the cost-effectiveness of fiscal measures applied in remote community food stores for Aboriginal Australians. Six price discount strategies on fruit, vegetables, diet drinks and water were modelled. Baseline diet was measured as 12 months' actual food sales data in three remote Aboriginal communities. Discount-induced changes in food purchases were based on published price elasticity data while the weight of the daily diet was assumed constant. Dietary change was converted to change in sodium and energy intake, and body mass index (BMI) over a 12-month period. Improved lifetime health outcomes, modelled for the remote population of Aboriginal and Torres Strait Islanders, were converted to disability adjusted life years (DALYs) saved using a proportional multistate lifetable model populated with diet-related disease risks and Aboriginal and Torres Strait Islander rates of disease. While dietary change was small, five of the six price discount strategies were estimated as cost-effective, below a $50,000/DALY threshold. Stakeholders are committed to finding ways to reduce important inequalities in health status between Aboriginal and Torres Strait Islanders and non-Indigenous Australians. Price discounts offer potential to improve Aboriginal and Torres Strait Islander health. Verification of these results by trial-based research coupled with consideration of factors important to all stakeholders is needed. © 2015 The Authors.

This study was to investigate the preventive effect of taemyeongcheong (TMC, a Korean traditional health drink) on acetaminophen (APAP, 800 mg/kg BW)-induced hepatic damage in ICR mice. TMC is prepared from Saururus chinensis, Taraxacum officinale, Zingiber officinale, Cirsium setidens, Salicornia herbacea, and Glycyrrhizae. A high dose of TMC (500 mg/kg BW) was found to decrease APAP-induced increases in serum levels of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and lactate dehydrogenase. TMC pretreatment also increased the hepatic levels of hepatic catalase, superoxide dismutase, glutathione peroxidase, and glutathione, and reduced serum levels of the inflammatory cytokines tumor necrosis factor (TNF)-α and interleukin (IL)-6 in mice administered APAP (Phepatic mRNA levels of TNF-α, IL-1β, IL-6, COX-2, and iNOS by 87%, 84%, 89%, 85%, and 88%, respectively, in mice treated with APAP (Phepatic damage.

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

We explore optimal growth conditions for superconducting Nd 1+x Ba 2-x Cu 3 O 7 (NdBCO) thin films deposited under various oxygen pressures in the range of 100-800 mTorr. In this study we address spatial inhomogeneity, growth orientation, impurity phases, cation disorder, and oxygen deficiency of NdBCO thin films by using micro-Raman scattering. The films grown in the low oxygen pressure range of 100-200 mTorr show predominantly a-axis orientation and degraded superconducting properties with a critical temperature (T c ) of ∼80 K. The degradation of the transition temperature of the films deposited at lower oxygen pressure is attributed to the cation disorder, on the basis of analysis of the apical oxygen Raman mode. On the other hand, the samples grown in the higher oxygen pressure range of 400-800 mTorr show strong c-axis orientation and much less cation disorder. These features correlate with their high values of T c and J c

The spectrum, brightness, and energy have been measured for the electromagnetic radiation emitted by a plasma produced in air near a solid surface by pulses from a high-power CO 2 laser. The air pressure was varied over the range p 0 = 0.1--760 torr, and the laser power density was varied over the range q = 5 x 10 6 --10 8 W/cm 2 . At p 0 > or approx. =2--5 torr the radiation properties of the plasma are determined by a laser-beam absorption wave which arises in the gas. The maximum brightness temperature, T/sub b/approx. =50 000 K (lambda = 400 +- 20 nm), is reached at p 0 = 25 torr. The emission spectrum is quite different from an equilibrium spectrum, consisting primarily of NII, OII, and NIII lines. The total energy radiation by the plasma in the wavelength interval 360--2600 nm into a solid angle of 4π sr reaches 2.3% of the laser pulse energy

Highly ionized plasmas are being used as a medium for charge neutralizing heavy ion beams in order to focus the ion beam to a small spot size. A radio frequency (RF) plasma source has been built at the Princeton Plasma Physics Laboratory (PPPL) in support of the joint Neutralized Transport Experiment (NTX) at the Lawrence Berkeley National Laboratory (LBNL) to study ion beam neutralization with plasma. The goal is to operate the source at pressures ∼ 10 -5 Torr at full ionization. The initial operation of the source has been at pressures of 10 -4 -10 -1 Torr and electron densities in the range of 10 8 -10 11 cm -3 . Recently, pulsed operation of the source has enabled operation at pressures in the 10 -6 Torr range with densities of 10 11 cm -3 . Near 100% ionization has been achieved. The source has been integrated with the NTX facility and experiments have begun

The storage ring vacuum system for the Pohang Light Source (PLS) has been designed to maintain the vacuum pressure of 10 1 0 Torr which requires UHV welding to have helium leak rate less than 1x10 1 0 Torr·L/sec. In order to develop new technique (PLS) welding technique), a prototype vacuum chamber has been welded by using Tungsten Inert Gas welding method and all the welded joints have been tested with a non-destructive method, so called helium leak detection, to investigate the vacuum tightness of the weld joints. The test was performed with a detection limit of 1x10 1 0 Torr·L/sec for helium and no detectable leaks were found for all the welded joints. Thus the performance of welding technique is proven to meet the criteria of helium leak rate required in the PLS Storage Ring. Both the principle and the procedure for the helium leak detection are also discussed

Identification of tokamak plasma parameters and investigation on the effects of each parameter on the plasma characteristics is important for the better understanding of magnetohydrodynamic (MHD) activities in the tokamak plasma. The effect of different hydrogen pressures of 1.9, 2.5 and 2.9 Torr on MHD fluctuations of the IR-T1 tokamak plasma was investigated by using of 12 Mirnov coils, singular value decomposition and wavelet analysis. The parameters such as plasma current, loop voltage, power spectrum density, energy percent of poloidal modes, dominant spatial structures and temporal structures of poloidal modes at different plasma pressures are plotted. The results indicate that the MHD activities at the pressure of 2.5 Torr are less than them at other pressures. It also has been shown that in the stable area of plasma and at the pressure of 2.5 Torr, the magnetic force and the force of plasma pressure are in balance with each other and the MHD activities are at their lowest level.

Deuteriding of thin titanium films: the effect of carbon monoxide surface contamination

Malinowski, M.W.

1976-02-01

The effect of adsorbed CO on the deuteriding of thin titanium films at room temperature was measured at D 2 pressures between 10 to 25 mtorr on films contaminated with CO exposures ranging between approximately 10 -8 torr-seconds (''clean'') to 10 -4 torr-seconds. In all measurements, for deuterium/titanium atom ratios greater than .2, the deuteriding appeared to be initally limited by the sticking of D 2 on the clean or contaminated titanium deuteride surface; the effective sticking coefficient on a clean titanium deuteride surface was approximately 3 x 10 -3 , while on a surface contaminated with 10 -4 torr-seconds of CO, the coefficient was reduced to approximately, 2 x 10 -4 . The pumping speeds of Ti films were dramatically different when the films were evaporated over TiD 2 . These changes were attributed to the presence of deuterium which diffused from the substrate film into the overlayer film

Full Text Available BackgroundAcute respiratory illnesses with cough (ARIwC are predominant causes of morbidity in Australian Indigenous children; however, data on disease burden in urban communities are scarce. This study aimed to determine the incidence of ARIwC, the predictors of recurrent (≥4 episodes ARIwC, and development of chronic cough following an ARIwC in urban, predominantly Indigenous, children aged <5 years from northern Brisbane, Australia.MethodsProspective cohort study of children aged <5 years registered with a primary healthcare center. ARIwC episodes and outcomes were collected for 12 months. Recurrent ARIwC was defined as ≥4 episodes in 12 months. Chronic cough was defined as cough lasting >4 weeks. Children who developed chronic cough were reviewed by a pediatric pulmonologist. Incidence densities per child-month of observation were calculated and predictors of recurrent ARIwC and chronic cough were evaluated in logistic regression models.ResultsBetween February 2013 and November 2015, 200 children were enrolled; median age of 18.1 months, range (0.7–59.7 months and 90% identified as Indigenous. A total of 1,722 child-months of observation were analyzed (mean/child = 8.58, 95% CI 8.18–9.0. The incidence of ARIwC was 24.8/100 child-months at risk (95% CI 22.3–27.5. Twenty-one children (10.5% experienced recurrent ARIwC. Chronic cough was identified in 70/272 (25.7% episodes of ARIwC.

The longitudinal variation of the electron concentration in large amplitude moving striations, computed theoretically by Stewart, has been tested experimentally. The measurements are carried out by means of a sampling probe technique in the glow discharge of neon (I = 105 mA, 2R = 5.6 cm, p 0 = 0.79 torr) and of argon (I = 75 mA, 2R = 5.7 cm, p 0 = 0.46 torr). It is found that the measured dependence of the concentration is not consistent with the theory. (Auth.)

Vacuum characteristics of the RF-cavity for TRISTAN main ring were tested. An APS (Alternating Periodic Structure) 18-cell cavity unit was made of low carbon steel S25C, and inner surface was electro-plated with copper of 100 μm in a pyrophosphorous-acid bath. After 24-hours bake-out at 140 deg C by a boiler, the outgassing rate of a test cavity was mainly dominated by the hydrogen permeation from the cooling water channel through the low carbon steel wall into the vacuum. By the use of anti-corrosion agent, the outgassing rate of the test cavity was decreased down to 1 x 10 -13 Torr · l/sec · cm 2 , after the bake-out at 140 deg C for 24 hours. After hydrogen degassing at 140 deg C for 10-days, the APS cavity unit was baked at 140 deg C for 24 hours, the ultimate pressure of the cavity reached down to 6 x 10 -10 Torr, and 2.7 x 10 -10 Torr, pumped by four 300 l/sec ion-pumps and by two 300 l/sec ion-pumps and two Ti-sublimation pumps with liquid nitrogen shroud respectively. The APS cavity unit was conditioned up to 250 kW/9-cell for 36 hours pumped by four 300 l/sec ion pumps, the ultimate pressure of the cavity was 5 x 10 -9 Torr with the RF power of 150 kW/9-cell on.

In this paper a method for polymerization of fluorocarbon gas in argon plasma to obtain a novel granular structure was reported. We prepared granular films where FeCo fine particles were distributed in plasma-polymerized fluorocarbon matrix by a facing-targets RF magnetron sputtering method, and investigated the correlation between their structures and magnetic properties. The magnetization of the films prepared with the partial pressure of fluorocarbon gas between 0 and 1.0 mTorr decreased linearly, because the FeCo content in a unit volume of a film decreased when a polymerized material was used as the matrix. However, the coercivity of the films decreased drastically with increasing the partial pressure of fluorocarbon gas above 0.4 mTorr. This is because the magnetic anisotropy of FeCo particles is decreased by the decrease of grain size. It was confirmed by a TEM observation that the FeCo-(C 4 F 8 ) n films had the granular structure which was constituted by the very fine FeCo particles and the plasma-polymerized fluorocarbon matrix. For the film deposited at the partial pressure of fluorocarbon gas of 0.4 mTorr, the size of FeCo magnetic particles is about 20 nm. On the other hand, the size of FeCo particles is decreased to about 8 nm when the film deposited at the partial pressure of fluorocarbon gas of 0.8 mTorr and its distribution is small

19F NMR spin-lattice relaxometry of hexafluorobenzene (HFB) has been shown to be a highly sensitive indicator of tumor oxygenation. In this study hexamethyldisiloxane (HMDSO) was identified as a proton NMR analog, and its potential as a probe for investigating dynamic changes in tissue oxygen tension (pO2) was evaluated. HMDSO has a single proton resonance (delta= -0.3 ppm) and the spin-lattice relaxation rate, Rl (= 1/T1) exhibits a linear dependence on pO2: R1 (s(-1)) = 0.1126 + 0.0013* pO2 (torr) at 37 degrees C. To demonstrate application in vivo, HMDSO was administered into healthy rat thigh muscle (100 microl) and tumors (50 microl). Local pO2 was determined by using pulse-burst saturation recovery (PBSR) 1H NMR spectroscopy to assess R1. Water and fat signals were effectively suppressed by frequency-selective excitation of the HMDSO resonance. Rat thigh muscle had a mean baseline pO2 of 35 +/- 11 torr, with a typical stability of +/-3 torr over 20 min, when the rats breathed air. Altering the inhaled gas to oxygen produced a significant increase in pO2 to 100-200 torr. In tumors, altering the inspired gas also produced significant (albeit generally smaller) changes. This new pO2 reporter molecule offers a potentially valuable new tool for investigating pO2 in vivo. (c) 2006 Wiley-Liss, Inc.

A knowledge of the distribution of oxygen tension (PO2) and vascularization in neoplasia has been fundamental to understanding relationships between tumor growth, hypoxia, and therapy. We have combined recessed oxygen microcathode and freeze-substitution techniques to correlate in situ PO2 profiles and morphologic features in 7,12-dimethylbenz(a)anthracene (DMBA) tumors in rats. Overlying connective tissue of transplanted tumor was exposed by a 1-2 mm incision and a cross-stitch pattern demarcated electrode puncture sites for histologic reference. Three buffered salt solutions (BSS) with different PO2 were each allowed to flow through a well over the tumor where electrodes were placed for calibration. Zero electrode oxygen current was recorded from a buffered yeast-agar mixture of zero torr. PO2 was recorded at 5-mu intervals to approximately 1-2 mm. Atmospheric contamination was eliminated by continuous well flow of BSS, 30 torr. Finally, the tumor and surrounding tissues were quick-frozen in vivo with Freon 22 and liquid nitrogen. The tissue block was freeze-substituted and sectioned. PO2 profiles were superimposed onto correspondingly scaled photomicrographs. A viable periphery with a PO2 range of 50-82 torr and a transition to necrotic areas of PO2, 2-13 torr were observed. This transition was characterized by PO2 gradients within distances of 50-300 mu at variable puncture depths. This technique should be useful in further studies of growth, necrosis, and therapy.

1. Ecological restoration must achieve functional as well as structural recovery. Functional metrics for reestablishment of trophic interactions can be used to complement traditional monitoring of structural attributes. In addition, topographic effects on food web structure provide added information within a restoration context; often, created sites may require spatial heterogeneity to effectively match structure and function of natural habitats. 2. We addressed both of these issues in our study of successional development of benthic food web structure, with focus on bottom–up driven changes in macroinvertebrate consumer assemblages in the salt marshes of the Venice Lagoon, Italy. We combined quantified estimates of the changing community composition with stable isotope data (13C:12C and 15N:14N) to compare the general trophic structure between created (2–14 years) marshes and reference sites and along topographic elevation gradients within salt marshes. 3. Macrofaunal invertebrate consumers exhibited local, habitat-specific trophic patterns. Stable isotope-based trophic structure changed with increasing marsh age, in particular with regards to mid-elevation (Salicornia) habitats. In young marshes, the mid-elevation consumer signatures resembled those of unvegetated ponds. The mid elevation of older and natural marshes had a more distinct Salicornia-zone food web, occasionally resembling that of the highest (Sarcocornia-dominated) elevation. In summary, this indicates that primary producers and availability of vascular plant detritus structure consumer trophic interactions and the flow of carbon. 4. Functionally different consumers, subsurface-feeding detritivores (Oligochaeta) and surface grazers (Hydrobia sp.), showed distinct but converging trajectories of isotopic change over time, indicating that successional development may be asymmetric between ‘brown’ (detrital) guilds and ‘green’ (grazing) guilds in the food web. 5.

A capacitively coupled radiofrequency (rf) (13.56 MHz) cylindrical argon micro-discharge expanding into a larger glass tube is studied by performing optical and electrical measurements over a pressure range 0.3–5 Torr and a rf power range 5–40 W. Measurements of the axial and radial plasma density profiles at the Paschen minimum near 1.5 Torr are used to develop a global model of the discharge and estimate neutral heating from ion–neutral charge exchange collisions for micro-propulsion applications.

An all aluminum components was developed for use with UHV system. Aluminum alloy whose advantage are little discharge gas, easy to bake out, light weight, little damage against radieactivity radiation is used. Therefore, as it is all aluminum alloy, baking is possible. Baking temperature is 150 deg C in case of not only ion pump, gate valve, angle valve but also aluminum components. Ion pump have to an ultrahigh vacuum of order 10 -9 torr can be obtained without baking, 10 -10 torr order can be obtained after 24 hour of baking. (author)

Nanosize powders of carbons were tried to be synthesized by pulsed discharge of graphite wires in several kinds of ambient gases. When the wire was discharged in N{sub 2} gas, nanosize powders have been successfully produced. The result of X-ray diffraction analysis indicated that nanosize powders produced in N{sub 2} gas at 750 Torr were amorphous carbon containing glassy carbons, while mass-spectrum analysis demonstrated the production of fullerenes at 600 Torr. If the wire is discharged in Ar gas, dielectric breakdown takes place between electrodes, producing no carbon powders. (author)

We purified an extracellular hemoglobin with the molecular mass of ca. 440 kDa from the whole homogenates of Oligobrachia mashikoi (phylum Pogonophora) by a one-step gel-filtration. The preparation was pure to be crystallized. The P50 values of the hemoglobin and the fresh blood prepared from O. mashikoi were about 0.82 Torr and 0.9 Torr, respectively, which were much lower than the P50 value of human hemoglobin. However, the n values of the hemoglobin and the blood were about 1.2 and 1.1, re...

Two metre long, cylindrical vacuum chambers of diameter ranging from 34 to 100 mm, coated with TiZrV getter films by sputtering, have been baked for about 24 h at temperatures from 120 to 250 degrees C. The ultimate pressures achieved after bakeout were found to correspond to the ratio of the pressure gauge degassing to the effective pumping speed provided by the chamber at the location of the gauge. The results covering a pressure range from 10/sup -11/ Torr down to 10 /sup -13/ Torr are presented and discussed. (6 refs).
