Jenkins, James

2011-09-01

I will present some new analysis of the PZ Tel system, which has recently been shown to host a young companion with a mass of around 30 Jupiter-masses, along with a debris disk of around 0.3 Lunar-masses. We have reanalyzed the iron abundance of the host star using our new spectral synthesis method, and contrary to previous results, we find the star to be super metal-rich, with a metallicity ([Fe/H]) of 0.2 dex. We also find the age of the system from chromospheric activities and pre-main sequence evolutionary models to be around 25Myrs. I will show some comparisons between the companion's bulk properties, such as broadband colours, and some of the latest evolutionary models as a function of metallicity. Finally, I will use these results to show how the companion to PZ Tel could be the first directly imaged extreme-Jovian extrasolar planet and not a low-mass brown dwarf.

Otic barotrauma is common among air travellers and can cause severe otalgia, perforation of the tympanic membrane and hearing loss. Many prevention measures exist, with varying evidence to support their use. There are no data to establish if air travellers are aware of them or indeed use them. We aimed to establish air travellers' knowledge of such prevention measures. We surveyed air travellers at two UK airports by means of a questionnaire. Answers to the questionnaire were collected over a two-week period. Overall, 179 air travellers with a mean age of 28 years (range: 15-72 years) completed the questionnaire. There were 66 female and 113 male air travellers. The majority (84 per cent) complained of symptoms while flying and 30 per cent were not aware of any prevention measures. Barotrauma-related symptoms were reported in 25 per cent of air travellers who were unaware of any prevention measures. Nearly all air travellers (86 per cent) indicated that more information regarding prevention measures would be useful. Air travellers are often not aware of prevention measures to avoid otic barotrauma, and the majority suffer as a result. Increasing public awareness of simple prevention measures would have a significant impact on air travellers.

The goal of this program is to acquire a FUSE spectrum of the symbiotic binary RR Tel. With these data, we plan to derive improved constraints on the hot component, the nebula, and perhaps the red giant wind. Based on results from AG Dra, we should also be able to use some line detections to improve atomic parameters for high ionization emission lines. This results would benefit the general FUSE community. As of this writing, the FUSE observation of RR Tel has not been made. Because RR Tel is a very bright UV source, the FUSE team is assessing the likelihood that RR Tel will have an adverse affect on the instrument.

The ataxia-telangiectasia mutated (ATM) protein is an apical kinase that orchestrates the multifaceted DNA-damage response. Normally, ATM kinase is in an inactive, homodimer form and is transformed into monomers upon activation. Besides a conserved kinase domain at the C terminus, ATM contains three other structural modules, referred to as FAT, FATC and N-terminal helical solenoid. Here we report the first cryo-EM structure of ATM kinase, which is an intact homodimeric ATM/Tel1 from Schizosaccharomyces pombe. We show that two monomers directly contact head-to-head through the FAT and kinase domains. The tandem N-terminal helical solenoid tightly packs against the FAT and kinase domains. The structure suggests that ATM/Tel1 dimer interface and the consecutive HEAT repeats inhibit the binding of kinase substrates and regulators by steric hindrance. Our study provides a structural framework for understanding the mechanisms of ATM/Tel1 regulation as well as the development of new therapeutic agents.

Pollution prevention for cleaner air: EPA's air and energy engineering research laboratory

The article discusses the role of EPA's Air and Energy Engineering Research Laboratory (AEERL) in pollution prevention research for cleaner air. For more than 20 years, AEERL has been conducting research to identify control approaches for the pollutants and sources which contribute to air quality problems. The Laboratory has successfully developed and demonstrated cost-effective sulfur dioxide, nitrogen oxides, and particulate control technologies for fossil fuel combustion sources. More recently, it has expanded its research activities to include indoor air quality, radon, organic control, stratospheric ozone depletion, and global warming. AEERL also develops inventories of air emissions of many types. Over the last several years, it has made substantial efforts to expand research on pollution prevention as the preferred choice for air emissions reduction

Air pollution prevention at the Hanford Site: Status and recommendations

International Nuclear Information System (INIS)

Engel, J.A.

1995-08-01

With the introduction of the Clean Air Act Amendments of 1990 and other air and pollution prevention regulations, there has been increased focus on both pollution prevention and air emissions at US DOE sites. The Pollution Prevention (P2) Group of WHC reviewed the status of air pollution prevention with the goal of making recommendations on how to address air emissions at Hanford through pollution prevention. Using the air emissions inventory from Hanford's Title V permit, the P2 Group was able to identify major and significant air sources. By reviewing the literature and benchmarking two other DOE Sites, two major activities were recommended to reduce air pollution and reduce costs at the Hanford Site. First, a pollution prevention opportunity assessment (P2OA) should be conducted on the significant painting sources in the Maintenance group and credit should be taken for reducing the burning of tumbleweeds, another significant source of air pollution. Since they are significant sources, reducing these emissions will reduce air emission fees, as well as have the potential to reduce material and labor costs, and increase worker safety. Second, a P2OA should be conducted on alternatives to the three coal-fired powerhouses (steam plants) on-site, including a significant costs analysis of alternatives. This analysis could be of significant value to other DOE sites. Overall, these two activities would reduce pollution, ease regulatory requirements and fees, save money, and help Hanford take a leadership role in air pollution prevention

Geomagnetic field measurements from the past few centuries show heightened secular variation activity in the southern hemisphere associated with the south Atlantic anomaly (SAA). It is uncertain whether geomagnetic anomalies at a similar scale have existed in the past owing to limited coverage and uncertainties in the paleomagnetic database. Here we provide new evidence from archaeological sources in the Levant suggesting a large positive northern hemisphere anomaly, similar in magnitude to the SAA during the 9th-8th centuries BCE, called ;Levantine Iron Age anomaly;. We also report an additional geomagnetic spike in the 8th century. The new dataset comprises 73 high precision paleointensity estimates from ca. 3000 BCE to 732 BCE, and five directional measurements between the 14th and the 9th centuries BCE. Well-dated pottery and cooking ovens were collected from twenty archaeological strata in two large contemporaneous stratigraphical mounds (tells) in Israel: Tel Megiddo and Tel Hazor. The new data are combined with previously published data and interpreted automatically using the PmagPy Thellier GUI program. The Tel Megiddo and Tel Hazor data sets demonstrate excellent internal consistency and remarkable agreement with published data from Mesopotamia (Syria). The data illustrate the evolution of an extreme geomagnetic high that culminated in at least two spikes between the 11th and the 8th centuries BCE (Iron Age in the Levant). The paleomagnetic directional data of the 9th century BCE show positive inclination anomalies, and deviations of up to 22° from the averaged geocentric axial dipole (GAD) direction. From comparison of the Levantine archaeomagnetic data with IGRF model for 2015 we infer the ;Levantine Iron Age anomaly; between the 10th and the 8th centuries BCE is a local positive anomaly. The eastward extent of the anomaly is currently unknown.

Air pollution is becoming a major health problem that affects millions of people worldwide. In support of this observation, the World Health Organization estimates that every year, 2.4 million people die because of the effects of air pollution on health. Mitigation strategies such as changes in diesel engine technology could result in fewer premature mortalities, as suggested by the US Environmental Protection Agency. This review: (i) discusses the impact of air pollution on respiratory disease; (ii) provides evidence that reducing air pollution may have a positive impact on the prevention of disease; and (iii) demonstrates the impact concerted polices may have on population health when governments take actions to reduce air pollution. © 2012 The Authors.

With the near-total recreation of African life, this paper examines the Neve Sha’anan neighborhood as supportive of the LGBT and migrant communities, evidencing the flourishing of national culture outside of traditional boundaries. Particularly, this paper looks at “The Prevention of Infiltration Law” to discuss ideas of “infiltrators” using frameworks from Foucault, Merleau-Ponty, Levinas, Jean-Luc Nancy and Achille Mbembe.

Military Parents' Personal Technology Usage and Interest in e-Health Information for Obesity Prevention.

Science.gov (United States)

Jai, Tun-Min; McCool, Barent N; Reed, Debra B

2016-03-01

U.S. military families are experiencing high obesity rates similar to the civilian population. The Department of Defense's Military Health System (MHS) is one of the largest healthcare providers in the United States, serving approximately 9.2 million active duty service members, retirees, spouses, and children. The annual cost to the MHS for morbidities associated with being overweight exceeds $1 billion. The preschool age has been suggested as an opportune time to intervene for the prevention of obesity. Thus, this study investigated the current level of technology usage by military service member families and assessed their needs and interests in health/nutrition information. This needs assessment is crucial for researchers/educators to design further studies and intervention programs for obesity prevention in military families with young children. In total, 288 military parents (233 Army and 55 Air Force) at two military bases whose children were enrolled in military childcare centers in the southwestern United States participated in a Technology Usage in Military Family (TUMF) survey in 2013. Overall, both bases presented similar technology usage patterns in terms of computer and mobile device usage on the Internet. Air Force base parents had a slightly higher knowledge level of nutrition/health information than Army base parents. The TUMF survey suggested practical ways such as mobile applications/Web sites, social networks, games, etc., that health educators can use to disseminate nutrition/health information for obesity prevention among military families with young children.

A theory of expert leadership (TEL) in psychiatry.

Science.gov (United States)

Goodall, Amanda H

2016-06-01

Leaders' technical competence - 'expert knowledge' - has been shown in many settings to be associated with better organizational performance. In universities, for example, there is longitudinal evidence that research-focused scholars make the best leaders; results from a hospital study show that doctors instead of professional managers are most closely associated with the best performing institutions. To explain these patterns, and raise hypotheses, a theory of expert leadership (TEL) has been developed that might explain these patterns. In this paper the framework for expert leadership is applied to psychiatry. The TEL proposes that psychiatric leaders, as opposed to non-expert managers, improve organizational performance through several channels. First, experts' knowledge influences organizational strategy. Second, having been 'one of them', a psychiatrist understands how to create the optimal work environment for psychiatric teams, through appropriate goal-setting, evaluation and support. These factors are positively associated with workers' wellbeing and performance. Third, exceptional psychiatrist-leaders are likely to set high standards for hiring. Fourth, leaders' credibility extends their influence among core workers, and also signals organizational priorities to stakeholders. Finally, a necessary prerequisite of TEL is that expert leaders have direct executive power inclusive of budgetary and strategic oversight. © The Royal Australian and New Zealand College of Psychiatrists 2015.

2011-12-01

The authorities of the canton of Neuchâtel, in the Western part of Switzerland, are willing to develop geothermal energy for district heating in the two main cities of the canton: Neuchâtel, located along the Lake of Neuchâtel, and La Chaux-de-Fonds situated in a high valley of the Jura Massif. The geology of both areas is linked to the Jura Range and present complex structures, where the landscape is composed of anticlines associated with overthrust faults, which are overcut by strike-slip fault and secondary faulting events. The rock formations go from the Trias, which forms the detachment layer, up to the Quaternary rock. Bedrocks are mainly composed of limestones and marls, which can reach a thickness of several hundreds meters. The three main deep aquifers investigated in this area, from the shallowest (≤ 400 m below surface) to deepest (geological models and 3D gravimetry models to best characterize the underground structures and to find areas where the rock properties would be favourable to geothermal exploitation. This means targets where permeability and porosity are high in the potential aquifers, allowing a significant flow at the future production wells. The results indicate that gravity anomalies are associated with both shallow and deep geological structures in the two exploration sites and that high resolution of dense grid gravity measurements combined with realistic 3D models of the geological structures allow to characterize interesting features for deep geothermal exploration. Gravity corrections were carried out with a computing code using different DEM resolution ranging from a very high resolution (0.5 m pixel in the vicinity of each station) toward a lower resolution (25 m for the distal areas as far as 110 km away from each station). The bathymetry of the Lake of Neuchâtel (218 km2) has been used to correct gravity effects from the large volume of water along the Lake shore of Neuchâtel.

2014-09-23

We report macular telangiectasia type 2 (MacTel) in a 34-year-old man, the youngest patient so far published with MacTel type 2. The patient presented with metamorphopsia and impaired reading ability. Diagnosis was based on bilateral abnormal macular autofluorescence, perifoveal telangiectasia with fluorescein angiographic hyperfluorescence without cystoid oedema, a small foveal avascular zone, asymmetric configuration of the foveal pit, disruptions in the inner segment/outer segment layer and hyper-reflective haze and spots in the outer nuclear layer. Although MacTel usually manifests with a slowly progressive decrease in visual acuity in the fifth to seventh decades of life, younger patients may occasionally be diagnosed with the disease. Awareness of subtle signs of the condition is essential for early diagnosis. 2014 BMJ Publishing Group Ltd.

Many people newly diagnosed with HIV are lost to follow-up before timely initiation of antiretroviral therapy (ART). A randomised controlled trial (RCT), WelTel Kenya1, demonstrated the effectiveness of the WelTel text messaging intervention to improve clinical outcomes among patients initiating ART. In preparation for WelTel Retain, an RCT that will evaluate the effect of the intervention to retain patients in care immediately following HIV diagnosis, we conducted an informative qualitative study with people living with HIV (n = 15) and healthcare providers (HCP) (n = 5) in October 2012. Study objectives included exploring the experiences of people living with HIV who have attempted to engage in HIV care, the use of cell phones in everyday life, and perceptions of communicating via text message with HCP. Participants were recruited through convenience sampling. Semi-structured, qualitative interviews were conducted and recorded, transcribed verbatim and analysed using NVivo software. Analysis was guided by the Theory of Reasoned Action and the Technology Acceptance Model. Results indicate that while individuals have many motivators for engaging in care after diagnosis, structural and individual barriers including poverty, depression and fear of stigma prevent them from doing so. All participants had access to a mobile phone, and most were comfortable communicating through text messages, or were willing to learn. Both people living with HIV and HCP felt that increased communication via the text messaging intervention has the potential to enable early identification of problems, leading to timely problem solving that may improve retention and engagement in care during the first year after diagnosis.

Full Text Available This building is a clear example of the efforts now being made by the new generations of Israel architects to develop a national architecture, based principally on prefabrication, and running contrary to the classic moulds so deeply rooted in the Middle East, and also to the strong wave of American style modernism. Up to now, this is the tallest building in Tel-Aviv. It consists of vertical pillars at ground level, which branch out into Y shaped supports at the second floor. A large block of apartments rises above these. The outer walls consist of prefabricated concrete parts; there is also a large trellice structure, made up of concrete units, which supports a number of projecting fittings; these provide shade and facilitate ventilation. This type of fittings has proved very useful throughout Israel as a means of solving the basic problem of shade against the sun and suitable ventilation.Constituye un claro exponente de la lucha que sostiene la. nueva generación de arquitectos, formados en Israel, por crear una arquitectura nacional propia—basada principalmente en la prefabricación—, contraria a los moldes clasicistas tan arraigados en el Oriente Medio y a la gran ola de arquitectura americanizante. El edificio, el más alto construido hasta la fecha, en la zona central de Tel-Aviv, arranca en planta baja de unos pilares verticales, que se abren en la planta primera en forma de Y, para sustentar el bloque de apartamentos. Los cerramientos de fachada están construidos con piezas prefabricadas de hormigón; y una gran celosía constituida por bloques de hormigón, a los cuales van adosadas unas piezas salientes que dan sombra y facilitan la ventilación, resolviendo acertadamente este problema fundamental en toda la arquitectura del país.

The shoot represents the basic body plan in land plants. It consists of a repeated structure composed of stems and leaves. Whereas vascular plants generate a shoot in their diploid phase, non-vascular plants such as mosses form a shoot (called the gametophore) in their haploid generation. The evolution of regulatory mechanisms or genetic networks used in the development of these two kinds of shoots is unclear. TERMINAL EAR1-like genes have been involved in diploid shoot development in vascular plants. Here, we show that disruption of PpTEL1 from the moss Physcomitrella patens, causes reduced protonema growth and gametophore initiation, as well as defects in gametophore development. Leafy shoots formed on ΔTEL1 mutants exhibit shorter stems with more leaves per shoot, suggesting an accelerated leaf initiation (shortened plastochron), a phenotype shared with the Poaceae vascular plants TE1 and PLA2/LHD2 mutants. Moreover, the positive correlation between plastochron length and leaf size observed in ΔTEL1 mutants suggests a conserved compensatory mechanism correlating leaf growth and leaf initiation rate that would minimize overall changes in plant biomass. The RNA-binding protein encoded by PpTEL1 contains two N-terminus RNA-recognition motifs, and a third C-terminus non-canonical RRM, specific to TEL proteins. Removal of the PpTEL1 C-terminus (including this third RRM) or only 16-18 amino acids within it seriously impairs PpTEL1 function, suggesting a critical role for this third RRM. These results show a conserved function of the RNA-binding PpTEL1 protein in the regulation of shoot development, from early ancestors to vascular plants, that depends on the third TEL-specific RRM.

The status of dermatoglyphics as a biomarker of Tel Hashomer camptodactyly syndrome: a review of the literature.

Science.gov (United States)

Wijerathne, Buddhika T B; Meier, Robert J; Agampodi, Suneth B

2016-09-20

Tel Hashomer camptodactyly syndrome is a rare disease and only a few cases have been reported. Dermatoglyphics potentially provide relevant phenotypic biomarkers that were initially noted as a vital clinical feature of this disease. Dermatoglyphics possibly can indicate growth disturbances that took place during early fetal development at the time when epidermal ridges were being formed into discernable patterns. Consequently, these intrauterine effects might well have occurred in association with the expression of the Tel Hashomer camptodactyly syndrome. Therefore, this review was undertaken to provide, as far as we know, the first attempt to broadly assess dermatoglyphic features that are connected with the Tel Hashomer camptodactyly syndrome. If a developmental association between dermatoglyphics and Tel Hashomer camptodactyly can be firmly established, this would probably document that Tel Hashomer camptodactyly disease has its origins during the early fetal period. A systematic literature search was conducted using articles from PubMed (Medline), POPLINE, Trip Database, Cochrane Library, and gray literature up to 31 March 2015. The review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Fourteen relevant publications were included in the review. There were 23 cases of patients with Tel Hashomer camptodactyly syndrome that were described in these published articles. We reviewed the dermatoglyphics of 21 available cases out of all of the published and electronically available cases of Tel Hashomer camptodactyly. Eight cases reported whorls to be the most common digital pattern with an expected rise of ridge count. Two cases show significantly high frequencies of arch patterns. Further, there were increased numbers of palmar creases, along with abnormal flexion creases or other palmar dermatoglyphic abnormalities reported in all cases. This review highlighted the desirability of thoroughly observing and

RanGTPase is involved in many cellular processes. It functions in nuclear-cytosolic transport and centrosome formation. Ran also localizes to chromatin as RCC1 does, its guanine nucleotide exchange factor, but Ran's function on chromatin is not known. We found that gsp1, a temperature-sensitive mutant of GSP1, a Saccharomyces cerevisiae Ran homologue, suppressed the hydroxyurea (HU) and ultra violet (UV) sensitivities of the mec1 mutant. In UV-irradiated mec1 gsp1 cells, Rad53 was phosphorylated despite the lack of Mec1. This suppression depended on the TEL1 gene, given that the triple mutant, mec1 gsp1 tel1, was unable to grow. The gsp1 mutations also suppressed the HU sensitivity of the rad9 mutant in a Tel1-dependent manner, but not the HU sensitivity of the rad53 mutant. These results indicated that Rad53 was activated by the Tel1 pathway in mec1 gsp1 cells, suggesting that Gsp1 helps regulate the role switching the ATM family kinases Mec1 and Tel1

High rates of sexually transmitted infections (STIs) and unintended pregnancy suggest a role for multipurpose prevention technologies (MPTs) designed to combine contraception and infection prophylaxis into one unified method. This study aims to determine factors associated with interest in MPTs among US women. We administered a national cross-sectional survey via MTurk. Eligibility criteria included female gender, age 18-29 years, residence in the USA, and sexual activity with a male partner in the past three months. In total, 835 surveys were suitable for analysis. Bivariable and multivariable logistic regressions were performed to determine factors associated with interest in MPTs. Eighty-three percent of women were interested in MPTs. Factors associated with interest included oral sex in the past three months (aOR 1.87, 95% CI 1.07, 3.53), recent use of oral contraceptive pills (OCPs; aOR 1.78, 95% CI 1.08, 2.93), HIV test within one year (aOR 2.10, 95% CI 1.29, 3.40), and increased STI worry score (aOR 1.98, 95% CI 1.36, 2.86). No use of contraception in the past three months was associated with decreased interest in MPTs (aOR 0.31, 95% CI 0.17, 0.58). HIV risk factors including race were not associated with MPT interest. Our data show that young, sexually active, US women are interested in MPTs. Women who used contraception, specifically OCPs, or evidenced concern for infection were most likely to be interested in such a product. Women reporting unsafe sexual habits were less likely to be interested, highlighting the importance of HIV/STI prevention education. Women in the USA are interested in multipurpose prevention technologies, particularly those women who currently use contraception or are concerned about their risk of infection. Our results emphasize the importance of moving forward with MPT development as well as continued HIV/STI prevention education. Copyright © 2017 Elsevier Inc. All rights reserved.

The emergency ward constitutes the main extra/intra-hospital interface most in demand by general physicians (GP). In order to evaluate the needs and the expectations of GP and, thus, to improve the cooperation between different partners, we underwent a study over 150 GP in Neuchâtel, Switzerland. The rate of participation within the time limit was 61.3%. The results showed that only 49% of GP find an interest in emergency medicine and less than a half (43%) feel not at ease when facing to vital emergencies. However 67% of GP confirmed being highly interested to attend special training in emergency field. The cooperation with medical emergency team (SMUR) and paramedics came out to be satisfactory. Facilities to access to the medico-technical platform of the emergency ward is also highly requested.

In order to develop the oligonucleotides to abolish an expression of TEL-AML1 chimeric RNA, which is a genetic aberration that causes the acute lymphoblastic leukemia (ALL), hammerhead ribozymes and deoxyoligoribozymes that can specifically cleave TEL-AML1 fusion RNA were designed. Constructs of the deoxyribozyme with an asymmetric substrate binding arm (Dz26) and the hammerhead ribozyme with a 4 nt-bulged substrate binding arm in the stem III (buRz28) were able to cleave TEL-AML1 chimeric RNA specifically at sites close to the junction in vitro, without cleaving the normal TEL and AML1 RNA. Single-turnover kinetic analysis under enzyme-excess condition revealed that the buRz28 is superior to the Dz26 in terms of substrate binding and RNA-cleavage. In conjunction with current progress in a gene-delivery technology, the designed oligonucleotides that specifically cleave the TEL-AML1 chimeric mRNA are hoped to be applicable for the treatment of ALL in vivo

The TEL-AML1 fusion protein of acute lymphoblastic leukemia modulates IRF3 activity during early B-cell differentiation.

Science.gov (United States)

de Laurentiis, A; Hiscott, J; Alcalay, M

2015-12-03

The t(12;21) translocation is the most common genetic rearrangement in childhood acute lymphoblastic leukemia (ALL) and gives rise to the TEL-AML1 fusion gene. Many studies on TEL-AML1 describe specific properties of the fusion protein, but a thorough understanding of its function is lacking. We exploited a pluripotent hematopoietic stem/progenitor cell line, EML1, and generated a cell line (EML-TA) stably expressing the TEL-AML1 fusion protein. EML1 cells differentiate to mature B-cells following treatment with IL7; whereas EML-TA display an impaired differentiation capacity and remain blocked at an early stage of maturation. Global gene expression profiling of EML1 cells at different stages of B-lymphoid differentiation, compared with EML-TA, identified the interferon (IFN)α/β pathway as a primary target of repression by TEL-AML1. In particular, expression and phosphorylation of interferon-regulatory factor 3 (IRF3) was decreased in EML-TA cells; strikingly, stable expression of IRF3 restored the capacity of EML-TA cells to differentiate into mature B-cells. Similarly, IRF3 silencing in EML1 cells by siRNA was sufficient to block B-lymphoid differentiation. The ability of TEL-AML1 to block B-cell differentiation and downregulate the IRF3-IFNα/β pathway was confirmed in mouse and human primary hematopoietic precursor cells (Lin- and CD34+ cells, respectively), and in a patient-derived cell line expressing TEL-AML1 (REH). Furthermore, treatment of TEL-AML1 expressing cells with IFNα/β was sufficient to overcome the maturation block. Our data provide new insight on TEL-AML1 function and may offer a new therapeutic opportunity for B-ALL.

Telomerase and Tel1p Preferentially Associate with Short Telomeres in S. cerevisiae

Science.gov (United States)

Sabourin, Michelle; Tuzon, Creighton T.; Zakian, Virginia A.

2009-01-01

SUMMARY In diverse organisms, telomerase preferentially elongates short telomeres. We generated a single short telomere in otherwise wild-type (WT) S. cerevisiae cells. The binding of the positive regulators Ku and Cdc13p was similar at short and WT-length telomeres. The negative regulators Rif1p and Rif2p were present at the short telomere, although Rif2p levels were reduced. Two telomerase holoenzyme components, Est1p and Est2p, were preferentially enriched at short telomeres in late S/G2 phase, the time of telomerase action. Tel1p, the yeast ATM-like checkpoint kinase, was highly enriched at short telomeres from early S through G2 phase and even into the next cell cycle. Nonetheless, induction of a single short telomere did not elicit a cell-cycle arrest. Tel1p binding was dependent on Xrs2p and required for preferential binding of telomerase to short telomeres. These data suggest that Tel1p targets telomerase to the DNA ends most in need of extension. PMID:17656141

The T-TEL Method for Assessing Water, Sediment, and Chemical Connectivity

Ali, Genevieve; Oswald, Claire; Spence, Christopher; Wellen, Christopher

2018-02-01

The concept of connectivity has been the subject of a great deal of recent research and provided new insights and breakthroughs on runoff generation processes and watershed biogeochemistry. However, a consensus definition and cohesive mathematical framework that would permit the consistent quantification of hydrologic connectivity, the examination of the interrelationships between water and material (e.g., sediment and chemicals) connectivity, or rigorous study intercomparison, have not been presented by the water resource community. Building on previous conceptualizations and site-specific or process-specific metrics, this paper aimed to review the current state of science on hydrologic connectivity and its role in water-mediated connectivity of material such as solutes and sediment before introducing a conceptual and a mathematical connectivity assessment framework. These frameworks rely on the quantification of Time scales, Thresholds, Excesses and Losses related to water and water-mediated material transport dynamics and are referred to as the T-TEL method. Through a small case study, we show how the T-TEL method allows a wide range of properties to be quantified, namely the occurrence, frequency, duration, magnitude, and spatial extent of water and water-mediated material connectivity. We also propose a research agenda to refine the T-TEL method and ensure its usefulness for facilitating the research and management of connectivity in pristine and human-impacted landscapes.

CK2 phospho-dependent binding of R2TP complex to TEL2 is essential for mTOR and SMG1 stability.

TEL2 interacts with and is essential for the stability of all phosphatidylinositol 3-kinase-related kinases (PIKKs), but its mechanism of action remains unclear. Here, we show that TEL2 is constitutively phosphorylated on conserved serines 487 and 491 by casein kinase 2 (CK2). Proteomic analyses establish that the CK2 phosphosite of TEL2 confers binding to the R2TP/prefoldin-like complex, which possesses chaperon/prefoldin activities required during protein complex assembly. The PIH1D1 subunit of the R2TP complex binds directly to the CK2 phosphosite of TEL2 in vitro and is required for the TEL2-R2TP/prefoldin-like complex interaction in vivo. Although the CK2 phosphosite mutant of TEL2 retains association with the PIKKs and HSP90 in cells, failure to interact with the R2TP/prefoldin-like complex results in instability of the PIKKs, principally mTOR and SMG1. We propose that TEL2 acts as a scaffold to coordinate the activities of R2TP/prefoldin-like and HSP90 chaperone complexes during the assembly of the PIKKs. Copyright © 2010 Elsevier Inc.

We evaluated the effectiveness of the US Air Force Suicide Prevention Program (AFSPP) in reducing suicide, and we measured the extent to which air force installations implemented the program. We determined the AFSPP's impact on suicide rates in the air force by applying an intervention regression model to data from 1981 through 2008, providing 16 years of data before the program's 1997 launch and 11 years of data after launch. Also, we measured implementation of program components at 2 points in time: during a 2004 increase in suicide rates, and 2 years afterward. Suicide rates in the air force were significantly lower after the AFSPP was launched than before, except during 2004. We also determined that the program was being implemented less rigorously in 2004. The AFSPP effectively prevented suicides in the US Air Force. The long-term effectiveness of this program depends upon extensive implementation and effective monitoring of implementation. Suicides can be reduced through a multilayered, overlapping approach that encompasses key prevention domains and tracks implementation of program activities.

Upper-room ultraviolet light and negative air ionization to prevent tuberculosis transmission.

2009-03-01

Full Text Available Institutional tuberculosis (TB transmission is an important public health problem highlighted by the HIV/AIDS pandemic and the emergence of multidrug- and extensively drug-resistant TB. Effective TB infection control measures are urgently needed. We evaluated the efficacy of upper-room ultraviolet (UV lights and negative air ionization for preventing airborne TB transmission using a guinea pig air-sampling model to measure the TB infectiousness of ward air.For 535 consecutive days, exhaust air from an HIV-TB ward in Lima, Perú, was passed through three guinea pig air-sampling enclosures each housing approximately 150 guinea pigs, using a 2-d cycle. On UV-off days, ward air passed in parallel through a control animal enclosure and a similar enclosure containing negative ionizers. On UV-on days, UV lights and mixing fans were turned on in the ward, and a third animal enclosure alone received ward air. TB infection in guinea pigs was defined by monthly tuberculin skin tests. All guinea pigs underwent autopsy to test for TB disease, defined by characteristic autopsy changes or by the culture of Mycobacterium tuberculosis from organs. 35% (106/304 of guinea pigs in the control group developed TB infection, and this was reduced to 14% (43/303 by ionizers, and to 9.5% (29/307 by UV lights (both p < 0.0001 compared with the control group.

2016-12-17

The Thermoelectric-Driven Liquid-Metal Plasma-Facing Structures (TELS) project was able to establish the experimental conditions necessary for flowing liquid metal surfaces in order to be utilized as surfaces facing fusion relevant energetic plasma flux. The work has also addressed additional developments along with progressing along the timeline detailed in the proposal. A no-cost extension was requested to conduct other relevant experiment- specifically regarding the characterization droplet ejection during energetic plasma flux impact. A specially designed trench module, which could accommodate trenches with different aspect ratios was fabricated and installed in the TELS setup and plasma gun experiments were performed. Droplet ejection was characterized using high speed image acquisition and also surface mounted probes were used to characterize the plasma. The Gantt chart below had been provided with the original proposal, indicating the tasks to be performed in the third year of funding. These tasks are listed above in the progress report outline, and their progress status is detailed below.

We have developed a Data Collection Module (DCM) to digitize, store and select data from the NuTel telescope, which observes Cherenkov photons from near horizontal air showers. Multi-anode photo-multiplier tubes (MAPMT) are used as photon-sensitive devices. DCM processes 32 input signals from the charge-sensitive pre-amplifiers located close to the MAPMT. The module design uses 40-MHz 10-bit pipeline ADCs and medium-size FPGAs. A programmable gain/attenuation control x0.5-2 is applied to each channel before the ADC providing a comfortable operation with a multi-channel system using MAPMT as photon-sensitive device because the gain of MAPMT fluctuates from channel to channel as 1:3. DCM has a flexible on-board trigger inside FPGA firmware. The system design is made in 32-bit 33-MHz cPCI. Thirty-two DCMs housed in two crates process signals from the two telescopes of 512 channels each looking to the same direction for coincidence

Full Text Available La telomerasa es la enzima responsable del mantenimiento de la longitud de los telómeros mediante la adición de secuencias repetitivas ricas en guanina, y su actividad se observa principalmente en gametos, células madre y células tumorales. En las células somáticas humanas el potencial de proliferación es limitado, alcanzando la senescencia luego de 50-70 divisiones celulares, debido a que la ADN polimerasa no es capaz de copiar el ADN en los extremos de los cromosomas. Por el contrario, en la mayoría de las células tumorales el potencial de replicación es ilimitado debido al mantenimiento de la longitud telomérica dado por la telomerasa. Los telómeros tienen proteínas adicionales que regulan la unión de la telomerasa. De la misma manera la telomerasa también se asocia con un complejo de proteínas que regulan su actividad. Este trabajo se centra en la estructura y función del complejo telómero/telomerasa y a cómo las alteraciones en su comportamiento conducen al desarrollo de diversas enfermedades, principalmente cáncer. El desarrollo de inhibidores del sistema telómero / telomerasa podría ser un blanco con posibilidades prometedoras.

Entre los resultados obtenidos se destaca que las TELS ocurren desde mayo hasta noviembre, en particular, en los meses de junio, julio y agosto. La mayoría se presenta durante horas de la tarde o de la noche, pero un grupo nada despreciable también ocurre durante la madrugada. Queda establecido que las TELS constituyen un elemento importante del clima de la ZMG que no puede ser ignorado desde el punto de vista científico y mucho menos en la práctica, por los efectos que produce en muchas ocasiones.

Survey of Oral Health Awareness in Neuchâtel 9th Graders.

Science.gov (United States)

Neuhaus, Klaus W; Müller, Magali E; Lussi, Adrian

The oral health habits of pupils had not yet been analyzed for the canton of Neuchâtel. A questionnaire was provided to 9th grade high school pupils (final year) of the three schools located in the Neuchâtel area to asses both oral health knowledge and habits in this connection. The average age was 15.5±0.8 years, and 78.1% of the questionnaires were returned. The prophylaxis program was conducted for a total of 4.5 h during pupils’ entire time at school. The results showed that both knowledge and oral health habits could be improved. As a positive outcome, 99% of the pupils brush their teeth before going to bed. Comparisons with similar 10-year-old studies from other cantons (Bern, Vaud) showed major differences in knowledge, for example on the importance of fluoridation. Only 54% of the pupils in Neuchâtel knew that fluoride offers some protection against caries, in spite of the fact that 89% thought that brushing with fluoridated toothpaste protects against caries. Most of the pupils used a fluoridated toothpaste. Furthermore, we found that self-reported sugar consumption was correlated with caries experience, but brushing frequency was not. We recommend introducing a review course for pupils in their last school year, in order to practice interdental cleaning, redefine appropriate, tooth-friendly snacks, and emphasize the importance of regular dental check-ups.

Air compliance through pollution prevention at Air Force Materiel Command facilities.

Energy Technology Data Exchange (ETDEWEB)

Kolpa, R.; Ryckman, S.J. Jr.; Smith, A.E.

1999-03-19

Options for air compliance through pollution prevention (P2) have been identified at 14 facilities of the US Air Force Materiel Command, ranging from depots with significant light industrial activity to laboratories. Previous P2 efforts concentrated on reducing hazardous and solid wastes, with any reduction in air impacts generally being a collateral benefit. This work focused on reducing air emissions and air compliance vulnerabilities. P2 options were identified in three stages. First, potentially applicable P2 options were identified from Internet and published information. Attention was given to identifying the types of sources to which an option could be applied, the option's state of development, and constraints that could limit its application. Traditional P2 options involving technology or equipment changes and material substitution were considered. In addition, newer approaches based on administrative ''controls'' were considered. These included inserting P2 into operating permits in exchange for administrative relief, privatization, derating boilers, and reducing an installation's potential to emit and compliance vulnerability by separating sources not under the Air Force's ''common control.'' Next, criteria and toxic emissions inventories by source category were prepared from inventory data supplied by facilities. The major problems at this stage were differences in the levels of detail provided by facilities and in the categories used by different installations. Emitting categories were matched to P2 option categories to identify candidate options. Candidates were screened to account for local regulations and technical information about sources in the inventories. When possible, emission reductions were estimated to help facility personnel prioritize options. Some options identified are being actively pursued by facilities to determine their site-specific feasibility. Although much work has been

2017-12-06

Mobile health (mHealth) applications have proliferated across the globe with much enthusiasm, although few have reached scale and shown public health impact. In this study, we explored how different contextual factors influenced the implementation, effectiveness and potential for scale-up of WelTel, an easy-to-use and evidence-based mHealth intervention. WelTel uses two-way SMS communication to improve patient adherence to medication and engagement in care, and has been developed and tested in Canada and Kenya. We used a comparative qualitative case study design, which drew on 32 key informant interviews, conducted in 2016, with stakeholders involved in six WelTel projects. Our research was guided by the Consolidated Framework for Implementation Research (CFIR), a meta-theoretical framework, and our analysis relied on a modified approach to grounded theory, which allowed us to compare findings across these projects. We found that WelTel had positive influences on the "culture of care" at local clinics and hospitals in Canada and Kenya, many of which stretched beyond the immediate patient-client relationship to influence wider organizational systems. However, these were mediated by clinician norms and practices, the availability of local champion staff, the receptivity and capacity of local management, and the particular characteristics of the technology platform, including the ability for adaptation and co-design. We also found that scale-up was influenced by different forms of data and evidence, which played important roles in legitimization and partnership building. Even with robust research evidence, scale-up was viewed as a precarious and uncertain process, embedded within the wider politics and financing of Canadian and Kenyan health systems. Challenges included juggling different interests, determining appropriate financing pathways, maintaining network growth, and "packaging" the intervention for impact and relevance. Our comparative case study, of a unique

Multifunctional Role of ATM/Tel1 Kinase in Genome Stability: From the DNA Damage Response to Telomere Maintenance

Science.gov (United States)

2014-01-01

The mammalian protein kinase ataxia telangiectasia mutated (ATM) is a key regulator of the DNA double-strand-break response and belongs to the evolutionary conserved phosphatidylinositol-3-kinase-related protein kinases. ATM deficiency causes ataxia telangiectasia (AT), a genetic disorder that is characterized by premature aging, cerebellar neuropathy, immunodeficiency, and predisposition to cancer. AT cells show defects in the DNA damage-response pathway, cell-cycle control, and telomere maintenance and length regulation. Likewise, in Saccharomyces cerevisiae, haploid strains defective in the TEL1 gene, the ATM ortholog, show chromosomal aberrations and short telomeres. In this review, we outline the complex role of ATM/Tel1 in maintaining genomic stability through its control of numerous aspects of cellular survival. In particular, we describe how ATM/Tel1 participates in the signal transduction pathways elicited by DNA damage and in telomere homeostasis and its importance as a barrier to cancer development.

The reciprocal translocation t(12;21)(p13;q22), the most common structural genomic alteration in B-cell precursor acute lymphoblastic leukaemia in children, results in a chimeric transcription factor TEL-AML1 (ETV6-RUNX1). We identified directly and indirectly regulated target genes utilizing an inducible TEL-AML1 system derived from the murine pro B-cell line BA/F3 and a monoclonal antibody directed against TEL-AML1. By integration of promoter binding identified with chromatin immunoprecipitation (ChIP)-on-chip, gene expression and protein output through microarray technology and stable labelling of amino acids in cell culture, we identified 217 directly and 118 indirectly regulated targets of the TEL-AML1 fusion protein. Directly, but not indirectly, regulated promoters were enriched in AML1-binding sites. The majority of promoter regions were specific for the fusion protein and not bound by native AML1 or TEL. Comparison with gene expression profiles from TEL-AML1-positive patients identified 56 concordantly misregulated genes with negative effects on proliferation and cellular transport mechanisms and positive effects on cellular migration, and stress responses including immunological responses. In summary, this work for the first time gives a comprehensive insight into how TEL-AML1 expression may directly and indirectly contribute to alter cells to become prone for leukemic transformation

2012-11-01

Full Text Available Abstract Background The cellular response to DNA damage is immediate and highly coordinated in order to maintain genome integrity and proper cell division. During the DNA damage response (DDR, the sensor kinases Tel1 and Mec1 in Saccharomyces cerevisiae and ATM and ATR in human, phosphorylate multiple mediators which activate effector proteins to initiate cell cycle checkpoints and DNA repair. A subset of kinase substrates are recognized by the S/T-Q cluster domain (SCD, which contains motifs of serine (S or threonine (T followed by a glutamine (Q. However, the full repertoire of proteins and pathways controlled by Tel1 and Mec1 is unknown. Results To identify all putative SCD-containing proteins, we analyzed the distribution of S/T-Q motifs within verified Tel1/Mec1 targets and arrived at a unifying SCD definition of at least 3 S/T-Q within a stretch of 50 residues. This new SCD definition was used in a custom bioinformatics pipeline to generate a census of SCD-containing proteins in both yeast and human. In yeast, 436 proteins were identified, a significantly larger number of hits than were expected by chance. These SCD-containing proteins did not distribute equally across GO-ontology terms, but were significantly enriched for those involved in processes related to the DDR. We also found a significant enrichment of proteins involved in telophase and cytokinesis, protein transport and endocytosis suggesting possible novel Tel1/Mec1 targets in these pathways. In the human proteome, a wide range of similar proteins were identified, including homologs of some SCD-containing proteins found in yeast. This list also included high concentrations of proteins in the Mediator, spindle pole body/centrosome and actin cytoskeleton complexes. Conclusions Using a bioinformatic approach, we have generated a census of SCD-containing proteins that are involved not only in known DDR pathways but several other pathways under Tel1/Mec1 control suggesting new

The U.S. Preventive Services Task Force (USPSTF) provides independent, objective, and scientifically rigorous recommendations for clinical preventive services. A primary concern is to avoid even the appearance of members having special interests that might influence their ability to judge evidence and formulate unbiased recommendations. The conflicts of interest policy for the USPSTF is described, as is the formal process by which best practices were incorporated to update the policy. The USPSTF performed a literature review, conducted key informant interviews, and reviewed conflicts of interest policies of ten similar organizations. Important findings included transparency and public accessibility; full disclosure of financial relationships; disclosure of non-financial relationships (that create the potential for bias and compromise a member's objective judgment); disclosure of family members' conflicts of interests; and establishment of appropriate reporting periods. Controversies in best practices include the threshold of financial disclosures, ease of access to conflicts of interest policies and declarations, vague definition of non-financial biases, and request for family members' conflicts of interests (particularly those that are non-financial in nature). The USPSTF conflicts of interest policy includes disclosures for immediate family members, a clear non-financial conflicts of interest definition, long look-back period and application of the policy to prospective members. Conflicts of interest is solicited from all members every 4 months, formally reviewed, adjudicated, and made publicly available. The USPSTF conflicts of interest policy is publicly available as part of the USPSTF Procedure Manual. A continuous improvement process can be applied to conflicts of interest policies to enhance public trust in members of panels, such as the USPSTF, that produce clinical guidelines and recommendations.

Full Text Available Abstract Objectives We have analyzed t(12;21(p13:q22 in an attempt to evaluate the frequency and prognostic significance of TEL-AML1 fusion gene in patients with childhood CD 10 positive B-ALL by fluorescence in situ hybridization (FISH. Also, we have monitored the prognostic value of this gene as a minimal residual disease (MRD. Methods All bone marrow samples of eighty patients diagnosed as CD 10 positive B-ALL in South Egypt Cancer Institute were evaluated by fluorescence in situ hybridization (FISH for t(12;21 in newly diagnosed cases and after morphological complete remission as a minimal residual disease (MRD. We determined the prognostic significance of TEL-AML1 fusion represented by disease course and survival. Results TEL-AML1 fusion gene was positive in (37.5% in newly diagnosed patients. There was a significant correlation between TEL-AML1 fusion gene both at diagnosis (r = 0.5, P = 0.003 and as a MRD (r = 0.4, P = 0.01 with favorable course. Kaplan-Meier curve for the presence of TEL-AML1 fusion at the diagnosis was associated with a better probability of overall survival (OS; mean survival time was 47 ± 1 month, in contrast to 28 ± 5 month in its absence (P = 0.006. Also, the persistence at TEL-AML1 fusion as a MRD was not significantly associated with a better probability of OS; the mean survival time was 42 ± 2 months in the presence of MRD and it was 40 ± 1 months in its absence. So, persistence of TEL-AML1 fusion as a MRD had no additive prognostic value over its measurement at diagnosis in terms of predicting the probability of OS. Conclusion For most patients, the presence of TEL-AML1 fusion gene at diagnosis suggests a favorable prognosis. The present study suggests that persistence of TEL-AML1 fusion as MRD has no additive prognostic value.

Kratzke, Cynthia; Wilson, Susan; Vilchis, Hugo

2013-02-01

The purpose of this study was to examine the breast cancer prevention information seeking behaviors among rural women, the prevalence of Internet, cell, and text use, and interest to receive breast cancer prevention information cell and text messages. While growing literature for breast cancer information sources supports the use of the Internet, little is known about breast cancer prevention information seeking behaviors among rural women and mobile technology. Using a cross-sectional study design, data were collected using a survey. McGuire's Input-Ouput Model was used as the framework. Self-reported data were obtained from a convenience sample of 157 women with a mean age of 60 (SD = 12.12) at a rural New Mexico imaging center. Common interpersonal information sources were doctors, nurses, and friends and common channel information sources were television, magazines, and Internet. Overall, 87% used cell phones, 20% had an interest to receive cell phone breast cancer prevention messages, 47% used text messaging, 36% had an interest to receive text breast cancer prevention messages, and 37% had an interest to receive mammogram reminder text messages. Bivariate analysis revealed significant differences between age, income, and race/ethnicity and use of cell phones or text messaging. There were no differences between age and receiving text messages or text mammogram reminders. Assessment of health information seeking behaviors is important for community health educators to target populations for program development. Future research may identify additional socio-cultural differences.

Conflict of interest in public health: should there be a law to prevent it?

Science.gov (United States)

Gupta, Arun; Holla, Radha; Suri, Shoba

2015-01-01

"Conflict of interest", now being commonly cited, is a set of circumstances that creates a risk that professional judgement or actions regarding a primary interest will be unduly influenced by a secondary interest. Conflict of interest situations can be institutional or personal, and can stem from financial or other interests including post-employment opportunities or during public -private partnerships. Conflicts of interest in the creation of public policy, especially health or nutrition related policies such as the vaccine policy, tobacco control, and research related to health, can have negative impact on the lives of millions of people. While the UN Convention Against Corruption, to which India is a signatory, identifies conflict of interest as often being a precursor to corruption, there is no serious action being taken in this direction by the Indian government, in spite of the fact there are instances of serious nature coming to light that affect our peoples lives. If conflict of interest situations are allowed to continue especially in health policy it could be detrimental to millions of people; therefore, it would be in public interest that India enacts a law to prevent conflict of interest in the making of public policies, comprehensive enough to include financial and institutional conflicts of interest.

Microcontrolled air-mattress for ulcer by pressure prevention

Science.gov (United States)

Pasluosta, Cristian F.; Fontana, Juan M.; Beltramone, Diego A.; Taborda, Ricardo A. M.

2007-11-01

An ulcer by pressure is produced when a constant pressure is exerted over the skin. This generates the collapse of the blood vessels and, therefore, a lack in the contribution of the necessary nutrients for the affected zone. As a consequence, the skin deteriorates, eventually causing an ulcer. In order to prevent it, a protocol must be applied to the patient, which is reflected on time and cost of treatment. There are some air mattresses available for this purpose, but whose performance does not fulfill all requirements. The prototype designed in our laboratory is based on the principle of the air mattress. Its objective is to improve on existing technologies and, due to an increased automation, reduce time dedication for personnel in charge of the patient. A clinical experience was made in the local Emergencies Hospital and also in an institution dedicated to aged patients care. In both cases, the results obtained and the comments from the personnel involved were favorable.

Gao, Guilin; Wang, Tianyi

2018-03-01

This article systematically expounds the status quo and sources of air pollution, the experience of foreign environmental tax policy, the advantages and disadvantages of environmental taxes levied in our country through literature research, historical analysis and comparative analysis and put forward recommendations on tax policy of prevention and control of air pollution by combining with the specific national conditions in our country. As one of the basic means of national macro-control, the tax policy is the major countermeasure that cannot be ignored in the prevention and control of air pollution. Studying the tax policy of prevention and control of air pollution will help to effectively control air pollution, develop a green economy and recycle economy and achieve the goal of improving environmental quality.

Roberto Martínez Pecino

2015-01-01

Full Text Available El ciberacoso es un fenómeno ampliamente analizado entre adolescentes, sin embargo en España ha sido poco estudiado entre jóvenes y particularmente en sus relaciones de noviazgo. Empleando una metodología cuantitativa este estudio analiza el ciberacoso mediante el teléfono móvil e Internet en las relaciones de noviazgo en una muestra compuesta por 336 estudiantes universitarios. El análisis de resultados indica que un 57,2% declara haber sido victimizado por su pareja mediante el teléfono móvil, y un 27,4% a través de Internet. El porcentaje de chicos victimizados fue mayor que el de las chicas. Un 47,6% declara haber acosado a su pareja a través del teléfono móvil, y un 14% a través de Internet. El porcentaje de chicos que lo ejerció fue superior al de las chicas. Los análisis de regresión muestran la relación entre haber sido victimizado por la pareja a través de uno de estos medios y el ejercicio del ciberacoso hacia la pareja mediante el mismo medio tecnológico. Los efectos de interacción ponen de manifiesto que los chicos victimizados a través del teléfono móvil o de Internet se implican, en mayor medida que las chicas victimizadas, como agresores en este fenómeno. Los resultados sugieren una modernización en los tipos de violencia que experimenta la juventud en sus relaciones de pareja.

Air Pollution and Allergic Airway Diseases: Social Determinantsand Sustainability in the Control and Prevention.

Science.gov (United States)

Paramesh, H

2018-04-01

Air pollution, global warming and climate change are the major contributing factors in causing the increase prevalence of allergic airway diseases like asthma and allergic rhinitis and they will be the defining issues for health system in the twenty-first century. Asthma is an early onset non-communicable environmental disease with global epidemic and contributes a greatest psycho socio economic burden. Nearly 8 million global deaths are from air pollution. Over one billion population are the sufferers during 2015 and will increase to 4 billion by 2050. Air pollution not only triggers the asthma episodes but also changes the genetic pattern in initiating the disease process. Over the years our concept of management of allergic airway disease has changed from control of symptoms to prevention of the disease. To achieve this we need positive development on clean air policies with standard norms, tracking progress, monitoring and evaluation, partnership and conventions with local and global authorities. We do have challenges to overcome like rapid urbanization, lack of multisectorial policy making, lack of finance for research and development and lack of monitoring exposure to health burden from air pollution. We need to prioritize our strategy by sustainable, safe, human settlement, cities, sustainable energy, industrialization, and research. The measures to be adopted are highlighted in this review article. With effective measures by all stake holders we can reduce air pollution and prevent the global warming by 2030, along with 194 countries as adopted by WHO in May 2015.

2016-04-01

Research Data Alliance's Interest Group on "Weather, Climate and Air Quality" More than ever in the history of Earth sciences, scientists are confronted with the problem of dealing with huge amounts of data that grow continuously at a rate that becomes a challenge to process and analyse them using conventional methods. Data come from many different and widely distributed sources, ranging from satellite platforms and in-situ sensors to model simulations, and with different degrees of openness. How can Earth scientists deal with this diversity and big volume and extract useful information to understand and predict the relevant processes? The Research Data Alliance (RDA, https://rd-alliance.org/), an organization that promotes and develops new data policies, data standards and focuses on the development of new technical solutions applicable in many distinct areas of sciences, recently entered in its third phase. In this framework, an Interest Group (IG) comprised of community experts that are committed to directly or indirectly enable and facilitate data sharing, exchange, or interoperability in the fields of weather, climate and air quality has been created recently. Its aim is to explore and discuss the challenges for the use and efficient analysis of large and diverse datasets of relevance for these fields taking advantage of the knowledge generated and exchanged in RDA. At the same time, this IG intends to be a meeting point between members of the aforementioned communities to share experiences and propose new solutions to overcome the forthcoming challenges. Based on the collaboration between several research meteorological and European climate institutes, but also taking into account the input from the private (from the renewable energies, satellites and agriculture sectors for example) and public sectors, this IG will suggest practical and applicable solutions for Big Data issues, both at technological and policy level, encountered by these communities.

A Context-Aware Indoor Air Quality System for Sudden Infant Death Syndrome Prevention

Directory of Open Access Journals (Sweden)

Daniel H. De La Iglesia

2018-03-01

Full Text Available Context-aware monitoring systems designed for e-Health solutions and ambient assisted living (AAL play an important role in today’s personalized health-care services. The majority of these systems are intended for the monitoring of patients’ vital signs by means of bio-sensors. At present, there are very few systems that monitor environmental conditions and air quality in the homes of users. A home’s environmental conditions can have a significant influence on the state of the health of its residents. Monitoring the environment is the key to preventing possible diseases caused by conditions that do not favor health. This paper presents a context-aware system that monitors air quality to prevent a specific health problem at home. The aim of this system is to reduce the incidence of the Sudden Infant Death Syndrome, which is triggered mainly by environmental factors. In the conducted case study, the system monitored the state of the neonate and the quality of air while it was asleep. The designed proposal is characterized by its low cost and non-intrusive nature. The results are promising.

[Simplicia and medical containers from the Jesuit pharmacy in Telč].

Science.gov (United States)

Hamrlová, Anna

2017-01-01

The Jesuit pharmacy in Telč was founded after 1657 within the premises of the Jesuit cloister; it survived the dissolution of Jesuits in 1773 and thanks to its purchase by the last pharmacist Ignac Lyro it was relocated to one of the houses in the square. During the stocktaking of the property and its sale, a detailed inventory of pharmacy equipment was recorded, including cabinets, laboratory tools, ingredients or drugs. The inventory is divided into parts of ingredients and prepared medications, the last lists recording the tools and containers for its preparation, production and preservation. The ingredients contain various parts of plants, minerals, precious stones or even parts of animals. The list is written mainly in the alphabetical order, in some cases with specified types of groups. Every item is provided with information about its price and quantity. Many ingredients originated from overseas countries, the areas of Jesuit missionary activities. Of the former rich equipment, only three pharmacy cabinets and a few containers, mainly veneer boxes and ceramic drug jars, have survived. All these parts together with the inventory give us a comparatively clear notion about the equipment and even facilities of the Jesuit apothecary in Telč, which sold items from different parts of the world. The Jesuit convent seems to be an important centre for town inhabitants not only in the 18th century; its legacy has remained in the local pharmacy till today.Key words: pharmacy Societas Jesus 18th century medications medical containers.

Full Text Available The WelTel Kenya1 trial demonstrated that text message support improved adherence to antiretroviral therapy (ART and suppression of HIV-1 RNA load. The intervention involved sending weekly messages to patients inquiring how they were doing; participants were required to respond either that they were well or that there was a problem.1 Describe problems participants identified through mobile phone support and reasons why participants did not respond to the messages; 2 investigate factors associated with indicating a problem and not responding; and 3 examine participant perceptions of the intervention.Secondary analysis of WelTel Kenya1 trial data.Reasons participants indicated a problem or did not respond were extracted from the study log. Negative binomial regression was used to determine participant characteristics associated with indicating a problem and non-response. Data from follow-up questionnaires were used to describe participant perceptions of the intervention.Between 2007 and 2009, 271 participants generated 11,873 responses; 377 of which indicated a problem. Health issues were the primary reason for problem responses (72%.

Study and application of measures for prevention of spontaneous combustion of coal in goaf induced by air leakage

Energy Technology Data Exchange (ETDEWEB)

Liu, Y.; Tang, H.; Zou, S.; Shi, S. [Xiangtan Mining Institute (China)

1996-12-01

To prevent spontaneous ignition of coal due to air leakage in the goaf, air stoppings were built periodically in a U-shaped air leakage area based on computer simulation and site experience. The measure had reduced remarkably the quantity and extent of air leakage in the mined-out area and expanded the extent of non-spontaneous combustion area, thus prevented effectively the risk of spontaneous ignition and gas explosion.

Air Toxics Under the Big Sky is an environmental science outreach/education program that incorporates the Next Generation Science Standards (NGSS) 8 Practices with the goal of promoting knowledge and understanding of authentic scientific research in high school classrooms through air quality research. A quasi-experimental design was used in order to understand: 1) how the program affects student understanding of scientific inquiry and research and 2) how the open inquiry learning opportunities provided by the program increase student interest in science as a career path . Treatment students received instruction related to air pollution (airborne particulate matter), associated health concerns, and training on how to operate air quality testing equipment. They then participated in a yearlong scientific research project in which they developed and tested hypotheses through research of their own design regarding the sources and concentrations of air pollution in their homes and communities. Results from an external evaluation revealed that treatment students developed a deeper understanding of scientific research than did comparison students, as measured by their ability to generate good hypotheses and research designs, and equally expressed an increased interest in pursuing a career in science. These results emphasize the value of and need for authentic science learning opportunities in the modern science classroom.

A pesar de ello, la manipulación de artefactos que conducen a que los estudiantes se formen una idea de los efectos de las oem es escasa, en gran medida por la falta de equipos de laboratorio adecuados. Debido a esta problemática, nuestra investigación nos condujo a utilizar el teléfono celular, tc, como instrumento de registro de las oem. Junto con los estudiantes, logramos construir un blindaje electromagnético para el tc y un reflector parabólico, en cuyo foco ubicamos un teléfono con conexión con el pc por el puerto usb para registrar las variaciones de la intensidad de la señal del operador celular.

Air bubbles induce a critical continuous stress to prevent marine biofouling accumulation

Belden, Jesse; Menesses, Mark; Dickenson, Natasha; Bird, James

2017-11-01

Significant shear stresses are needed to remove established hard fouling organisms from a ship hull. Given that there is a link between the amount of time that fouling accumulates and the stress required to remove it, it is not surprising that more frequent grooming requires less shear stress. One approach to mitigate marine biofouling is to continuously introduce a curtain of air bubbles under a submerged surface; it is believed that this aeration exploits the small stresses induced by rising bubbles to continuously prevent accumulation. Although curtains of rising bubbles have successfully prevented biofouling accumulation, it is unclear if a single stream of bubbles could maintain a clean surface. In this talk, we show that single bubble stream aeration can prevent biofouling accumulation in regions for which the average wall stress exceeds approximately 0.01 Pa. This value is arrived at by comparing observations of biofouling growth and prevention from field studies with laboratory measurements that probe the associated flow fields. We also relate the spatial and temporal characteristics of the flow to the size and frequency of the rising bubbles, which informs the basic operating conditions required for aeration to continuously prevent biofouling accumulation.

Tobacco plants were sprayed with benzimidazole before being exposed to 30 ppM of photochemical oxidants for a period of two hours. The plants were observed 48 hours after exposure and found to have suffered no toxic effects from the oxidants. It may be concluded that benzimidazole is an effective agent for preventing the toxic effects of air pollutants, such as photochemical oxidants on plants.

The rising prevalence of type 2 diabetes underlines the importance of secondary strategies for the prevention of target organ damage. While access to diabetes education centers and diabetes intensification management has been shown to improve blood glucose control, these services are not available to all that require them, particularly in rural and northern areas. The provision of these services through the Home Care team is an advance that can overcome these barriers. Transfer of blood glucose data electronically from the home to the health care provider may improve diabetes management. The study population will consist of patients with type 2 diabetes with uncontrolled A1c levels living on reserve in the Battlefords region of Saskatchewan, Canada. This pilot study will take place over three phases. In the first phase over three months the impact of the introduction of the Bluetooth enabled glucose monitor will be assessed. In the second phase over three months, the development of guidelines based treatment algorithms for diabetes intensification will be completed. In the third phase lasting 18 months, study subjects will have diabetes intensification according to the algorithms developed. The first phase will determine if the use of the Bluetooth enabled blood glucose devices which can transmit results electronically will lead to changes in A1c levels. It will also determine the feasibility of recruiting subjects to use this technology. The rest of the Diabetes Risk Evaluation and Management Tele-monitoring (DreamTel) study will determine if the delivery of a diabetes intensification management program by the Home Care team supported by the Bluetooth enabled glucose meters leads to improvements in diabetes management.

NEEDs for Bones (NFB), based on the Health Belief Model, is a 4-lesson osteoporosis-prevention curriculum for 11- to 14-year-olds. This study examined the relationship between enjoyment of food tastings and interest in NFB. NFB was administered by teachers as part of standard practice and evaluated after the fourth lesson using a 21-item survey. Significant clustering of students within classrooms required use of random-intercept multilevel ordinal regression models in SAS proc GLIMMIX, with students nested within classrooms. Analyses considered tasting experience, eating attitudes, sex, grade, and cohort. Students (N = 1619; 50% girls) participated from 85 fourth to eighth grade classrooms (47% sixth grade and 31% seventh grade) in 16 Pennsylvania SNAP-Ed eligible schools over 2 academic years. For all foods tasted, students who did not enjoy the food tasting were less interested in the lesson than students who did enjoy the food tasting (all p < .001); refried beans (odds ratio [OR] = 0.30), soy milk (OR = 0.55), cranapple juice (OR = 0.51), sunflower kernels (OR = 0.48), and Swiss cheese (OR = 0.49). The relationship persisted net of covariates. Enjoyment of food tasting activities can predict interest in nutrition education on osteoporosis prevention, supporting resource allocation and inclusion of food tasting activities in school-age nutrition education. © 2015, American School Health Association.

2017-09-01

The adoption of mobile technologies for health (mHealth) in healthcare has grown considerably in recent years, but systematic assessment of interest in the use of mHealth in HIV prevention efforts among people who use drugs (PWUD) is lacking. We therefore examined interest in use of mHealth technology in HIV prevention and associated individual-level factors among high-risk PWUD enrolled in methadone maintenance program. A total of 400 HIV-negative PWUD, who reported drug- and/or sex-related risk behaviors completed a standardized assessment using audio computer assisted self-interview (ACASI). Results revealed significant interest in using mHealth-based approaches for specific purposes, including: to receive medication reminders (72.3%), to receive information about HIV risk reduction (65.8%), and to assess HIV risk behaviors (76.5%). Multivariate analysis showed that interest in receiving medication reminders was associated with currently taking medication and being neurocognitively impaired, whereas interest in receiving HIV-risk reduction information was associated with being non-white, married, and perceiving the person was at high-risk for contracting HIV. Similarly, participants' interested in using mHealth for HIV risk behavior assessment was associated with having recently visited a healthcare provider and exhibiting depressive symptoms. Overall, this study demonstrated that high-risk PWUD are interested in using mHealth-based tools as a key part of an HIV prevention approach within a common type of drug treatment settings. Thus, formative research on preferences for design and functionality of mHealth-based HIV prevention tools are now needed, followed by practical development, implementation, and evaluation of these new intervention strategies.

US nuclear plants are implementing preventive maintenance (PM) tasks with little documented basis beyond fundamental vendor information to support the tasks or their intervals. The Preventive Maintenance Basis project provides utilities with the technical basis for PM tasks and task intervals associated with 40 specific components such as valves, electric motors, pumps, and HVAC equipment. This report provides an overview of the PM Basis project and describes use of the PM Basis database. This document provides a program of PM tasks suitable for application to Air Operated Valves (AOV's) in nuclear power plants. The PM tasks that are recommended provide a cost-effective way to intercept the causes and mechanisms that lead to degradation and failure. They can be used, in conjunction with material from other sources, to develop a complete PM program or to improve an existing program. Users of this information will be utility managers, supervisors, craft technicians, and training instructors responsible for developing, optimizing, or fine-tuning PM programs

Portable Filtered Air Suction System for Released Radioactive Gases Prevention under a Severe Accident of NPPs

International Nuclear Information System (INIS)

Gu, Beom W.; Choi, Su Y.; Rim, Chun T.

2013-01-01

In this paper, the portable filtered air suction system (PoFASS) for released radioactive gases prevention under a severe accident of NPP is proposed. This technology can prevent the release of the radioactive gases to the atmosphere and it can be more economical than FVCS because PoFASS can cover many NPPs with its high mobility. The conceptual design of PoFASS, which has the highest cost effectiveness and robustness to the environment condition such as wind velocity and precipitation, is suggested and the related previous research is introduced in this paper. The portable filtered air suction system (PoFASS) for released radioactive gases prevention can play a key role to mitigate the severe accident of NPP with its high cost effectiveness and robustness to the environment conditions. As further works, the detail design of PoFASS to fabricate a prototype for a demonstration will be proceeded. When released radioactive gases from the broken containment building in the severe accident of nuclear power plants (NPPs) such as the Chernobyl and Fukushima accidents occur, there are no ways to prevent the released radioactive gases spreading in the air. In order to solve this problem, several European NPPs have adopted the filtered vented containment system (FVCS), which can avoid the containment failure through a pressure relief capability to protect the containment building against overpressure. However, the installation cost of FVCS for a NPP is more than $10 million and this system has not been widely welcomed by NPP operating companies due to its high cost

The International Agency for Research on Cancer estimates that over half of the new cancer cases and almost two-thirds of the cancer deaths in 2012 occurred in low and middle income countries. To discuss the challenges and opportunities to reducing the burden of cancer worldwide, the Molecular Epidemiology and the Environment and the International Issues in Cancer Special Interest Groups joined forces to hold a session during the 38th Annual Meeting of the American Society of Preventive Oncology (March 2014, Arlington, Virginia). The session highlighted three topics of particular interest to molecular cancer prevention researchers working internationally, specifically: 1) biomarkers in cancer research; 2) environmental exposures and cancer; and 3) molecular pathological epidemiology. A major factor for successful collaboration illuminated during the discussion was the need for strong, committed, and reliable international partners. A key element of establishing such relationships is to thoroughly involve individual international collaborators in the development of the research question; engaged international collaborators are particularly motivated to champion and shepherd the project through all necessary steps, including issues relating to institutional review boards, political sensitivity, laboratory-based assays, and tumor subtyping. Also essential is allotting time for the building, maintaining, and investing in such relationships so that successful international collaborations may take root and bloom. While there are many challenges inherent to international molecular cancer research, the opportunities for furthering the science and prevention of cancer worldwide are great, particularly at this time of increasing cancer incidence and prevalence in low and middle income countries. ©2014 American Association for Cancer Research.

Engaged Learning and Youth Interest in STEM Careers: A Science Museum Exhibit on Air Pollution and Urban Sustainability

Science.gov (United States)

Stuart, A. L.

2012-12-01

Enrollments in science, technology, engineering, and mathematics (STEM) curricula currently lag workforce needs. Participation of women and minorities in STEM careers also remains low despite efforts to improve their representation in these fields. We discuss the development and evaluation of a science museum exhibit aimed at stimulating interest of middle school children (particularly girls) in STEM careers. The exhibit was designed to teach science, while addressing two factors identified as limiting the interest of girls in STEM fields — perceived lack of social relevance and lack of female role models. Further, it was designed to apply best practices in science education, including inquiry-based learning and interdisciplinary content. The exhibit was developed through collaboration between students and faculty researchers at the University of South Florida and science education and evaluation specialists at the Museum of Science and Industry of Tampa. A few stages of formative and summative assessment, including focus group discussions, visitor observation, and surveys were used to evaluate the effectiveness of the exhibit to educational project goals. The installed exhibit is focused on teaching content related to interactions between air pollution, urban design, and human health. The approximately 25 square foot exhibit space involves four different types of components. A three-dimensional model of a city, with underlying dynamic computer simulations, allows visitors to interactively explore relationships between city design, air pollution and exposures. A computer game, with quiz questions requiring user decisions on personal to community behavior, provides visual feedback regarding impacts on air pollution. Traditional panels with graphics and text, including results of current research, display integrative scientific content with open-ended questions to stimulate discussion. Finally, personal profiles highlight the diverse family, work, and social lives

Glaucoma drainage implant surgery is a treatment option for the management of neovascular glaucoma. However, tube obstruction by blood clot after Ahmed glaucoma valve (AGV) implantation is an unpredictable clinically challenging situation. We report 4 cases using intracameral air injection for the prevention of the tube obstruction of AGV by blood clot. The first case was a 57-year-old female suffering from ocular pain because of a tube obstruction with blood clot after AGV implantation in neovascular glaucoma. Surgical blood clot removal was performed. However, intractable bleeding was noted during the removal of the blood clot, and so intracameral air injection was performed to prevent a recurrent tube obstruction. After the procedure, although blood clots formed around the tube, the tube opening where air could touch remained patent. In 3 cases of neovascular glaucoma with preoperative severe intraocular hemorrhages, intracameral air injection and AGV implantation were performed simultaneously. In all 3 cases, tube openings were patent. It appears that air impeded the blood clots formation in front of the tube opening. Intracameral air injection could be a feasible option to prevent tube obstruction of AGV implant with a blood clot in neovascular glaucoma with high risk of tube obstruction.

The circulating air barrier: Effective prevention of liquid contaminant movement through soil

International Nuclear Information System (INIS)

Gill, R.; Towers, T.; Johnson, H.; Overbey, W.

1995-01-01

The environmental cleanup task facing the United States Department of Energy (DOE) presents enormous technical, planning and institutional challenges, including the need to develop new technologies that are faster, better, safer, and cheaper, in order to expedite site cleanup. Characterization of contaminated sediments resulting from past tank leaks, continued safe operations of the tanks, total confinement of leaking materials, secondary waste minimization, and final closure of the single shell tanks are five of the many facets of the storage tank issue at Hanford and elsewhere in the nation. Each of these issues are considered in the development of the Circulating Air Barrier (CAB). The Circulating Air Barrier system is a desiccant-type barrier designed to prevent the movement of liquid contaminants toward the groundwater by using an air circulation and processing system to lower the water saturation in a targeted subsurface zone below the saturation level required for liquid flow. Vertical or horizontal wells can be installed to create a matrix of air injection and production so that air flows across the target barrier zone to the production wells. In the event of a tank leak, the system serves as a tool for early detection and provides a means to withdraw volatile contaminants to the surface for treatment. Demonstration and full-scale CAB systems have been designed for the Hanford Site. This includes chemical and geological characterization; model development, sensitivity analysis and performance optimization; subsurface configuration and surface processing equipment design; and development of a test program with associated cost estimates

This randomized, single-blind study aimed to explore the effects of intra-operative warming with a forced-air warmer in the prevention of hypothermia after tourniquet deflation in elderly patients undergoing unilateral total knee replacement arthroplasty under general anaesthesia. Patients were randomized to receive either intra-operative warming using a forced-air warmer with an upper body blanket (warming group; n = 12) or no intra-operative warming (nonwarming group; n = 12). Oesophageal temperature was measured as core body temperature. At 30 min following tourniquet inflation, the core body temperature started to increase in the warming group whereas it continued to drop in the non-warming group. This difference was statistically significant. The final core body temperature after tourniquet deflation was significantly higher in the warming group (mean +/- SD 36.1 +/- 0.2 degrees C) than in the non-warming group (35.4 +/- 0.3 degrees C). Intra-operative forced-air warming increased the core body temperature before tourniquet deflation and prevented subsequent hypothermia in elderly patients under general anaesthesia.

Forced-air warming is a commonly used warming modality, which has been shown to reduce the incidence of inadvertent perioperative hypothermia (heating mattresses offer a potentially cheaper alternative, however, and one of the research recommendations from the National Institute for Health and Care Excellence was to evaluate such devices formally. We conducted a randomized single-blinded study comparing perioperative hypothermia in patients receiving resistive heating or forced-air warming. A total of 160 patients undergoing non-emergency surgery were recruited and randomly allocated to receive either forced-air warming (n=78) or resistive heating (n=82) in the perioperative period. Patient core temperatures were monitored after induction of anaesthesia until the end of surgery and in the recovery room. Our primary outcome measures included the final intraoperative temperature and incidence of hypothermia at the end of surgery. There was a significantly higher rate of hypothermia at the end of surgery in the resistive heating group compared with the forced-air warming group (P=0.017). Final intraoperative temperatures were also significantly lower in the resistive heating group (35.9 compared with 36.1°C, P=0.029). Hypothermia at the end of surgery in both warming groups was common (36% forced air warming, 54% resistive heating). Our results suggest that forced-air warming is more effective than resistive heating in preventing postoperative hypothermia. NCT01056991. © The Author 2016.

Breast cancer is the most common cancer and the second principal cause of cancer deaths among women worldwide, including Malaysia. This study focused on media choice and attempted to determine the communication channels mostly used and preferred by women in seeking information and knowledge about breast cancer. A cross sectional study was carried out to examine the breast cancer prevention information seeking behavior among 450 students at one private university in Malaysia. The mean age of respondents was 25±4.3 years. Common interpersonal information sources were doctors, friends, and nurses and common channel information sources were television, brochure, and internet. Overall, 89.9% used cell phones, 46.1% had an interest in receiving cell phone breast cancer prevention messages, 73.9% used text messaging, and 36.7% had an interest in receiving text breast cancer prevention messages. Bivariate analysis revealed significant differences among age, eduation, nationality and use of cell phones. Assessment of health information seeking behavior is important for community health educators to target populations for program development.

This paper presents a low-power integrated wireless telemetry system (Bio-WiTel) for healthcare applications in 401-406 MHz frequency band of medical device radiocommunication (MedRadio) spectrum. In this paper, necessary design considerations for telemetry system for short-range (upto 3 m) communication of biosignals are presented. These considerations help greatly in making important design decisions, which eventually lead to a simple, low power, robust, and reliable wireless system implementation. Transmitter (TX) and receiver (RX) of Bio-WiTel system have been fabricated in 180 nm mixed mode CMOS technology. While radiating -18 dBm output power to a 50 antenna, the packaged TX IC consumes 250 μW power in 100% on state from 1 V supply, whereas the RX IC consumes 990 μW power from 1.8 V supply with a sensitivity of -75 dBm. Measurement results show that TX fulfils the spectral mask requirement at a maximum data rate of 72 kb/s. The measured bit error rate (BER) of RX is less than for a data rate of 200 kb/s. The proposed Bio-WiTel system is tested successfully in home and hospital environments for the communication of electrocardiogram and photoplethysmogram signals at a data rate of 57.6 kb/s with a measured BER of <10 for a maximum distance of 3 m.

Pollution prevention and air quality

International Nuclear Information System (INIS)

Fuentes Hector; Tsihrintzis Vassilios

1997-01-01

Pollution prevention (P2) results from the combined effect of the public opinion, a new environmental value system, government regulation, but above all, the search for an economic development within the context of environmental protection. The reasons for prevention are fundamental: profit from a new economic frontier; reduced potential for civil and criminal liability; and the effective and economic protection of the environment. This paper addresses, among other relevant issues, the following topics: justification and objective of pollution prevention; strategy and methodology for its implementation; examples of successes and tools; benefits and barriers and some recommendation

2017-01-01

With rapid urbanization and development of transport infrastructure, air pollution caused by multiple-pollutant emissions and vehicle exhaust has been aggravated year by year in China. In order to improve air quality, the Chinese authorities have taken a series of actions to control air pollution emission load within a permissible range. However, although China has made positive progress on tackling air pollution, these actions have not kept up with its economy growth and fossil-fuel use. The traditional single-pollutant approach is far from enough in China now, and in the near future, air pollution control strategies should move in the direction of the multiple-pollutant approach. In addition, undesirable air quality is usually linked with the combination of high emissions and adverse weather conditions. However, few studies have been done on the influence of climate change on atmospheric chemistry in the global perspective. Available evidence suggested that climate change is likely to exacerbate certain kinds of air pollutants including ozone and smoke from wildfires. This has become a major public health problem because the interactions of global climate change, urban heat islands, and air pollution have adverse effects on human health. In this chapter, we first review the past and current circumstances of China's responses to air pollution. Then we discuss the control challenges and future options for a better air quality in China. Finally, we begin to unravel links between air pollution and climate change, providing new opportunities for integrated research and actions in China.

RR Tel: Determination of Dust Properties During Minimum Obscuration

Full Text Available the ISO infrared spectra and the SAAO long-term JHKL photometry of RR Tel in the epochs during minimum obscuration are studied in order to construct a circumstellar dust model. the spectral energy distribution in the near- and the mid-IR spectral range (1–15 μm was obtained for an epoch without the pronounced dust obscuration. the DUSTY code was used to solve the radiative transfer through the dust and to determine the circumstellar dust properties of the inner dust regions around the Mira component. Dust temperature, maximum grain size, dust density distribution, mass-loss rate, terminal wind velocity and optical depth are determined. the spectral energy distribution and the long-term JHKL photometry during an epoch of minimum obscuration show almost unattenuated stellar source and strong dust emission which cannot be explained by a single dust shell model. We propose a two-component model consisting of an optically thin circmustellar dust shell and optically thick dust outside the line of sight in some kind of a flattened geometry, which is responsible for most of the observed dust thermal emission.

Behavioral incentives have been used to encourage smoking cessation in older adolescents, but the acceptability of incentives to promote a smoke-free lifestyle in younger adolescents is unknown. To inform the development of novel, effective, school-based interventions for youth, we assessed middle school students' interest in participating in an incentive-based tobacco abstinence program. We surveyed 988 students (grades 6-8) attending three Connecticut middle schools to determine whether interest in program participation varied as a function of (1) intrapersonal factors (i.e., demographic characteristics (sex, age, race), smoking history, and trait impulsivity) and/or (2) aspects of program design (i.e., prize type, value, and reward frequency). Primary analyses were conducted using multiple regression. A majority of students (61.8%) reported interest in program participation. Interest did not vary by gender, smoking risk status, or offering cash prizes. However, younger students, non-Caucasian students, behaviorally impulsive students, and students with higher levels of self-regulation were more likely to report interest. Inexpensive awards (e.g., video games) offered monthly motivated program interest. In sum, middle school students reported high levels of interest in an incentive-based program to encourage a tobacco-free lifestyle. These formative data can inform the design of effective, incentive-based smoking cessation and prevention programs in middle schools.

Immediate management of traumatized teeth is often critical to the prognosis of the teeth. Most of the traumatic dental injuries occur at home, followed by school. There is a high probability that first aid would be given by lay people such as parents, teachers, or coaches. Knowledge of those people regarding emergency management of dental trauma is crucial for better prognosis. To investigate: (i) the knowledge of elementary school teachers regarding traumatic dental injuries to permanent teeth and emergency treatment, (ii) their source of information, and (iii) the demand for more education in dental trauma. A three-part questionnaire comprised of questions regarding demographic data, attitude, and knowledge about dental injuries was distributed to teachers in 12 elementary schools in the Tel-Aviv area, Israel. The average knowledge score was 4.59 (in a scale of 0-10). Three individual predictors significantly improved the respondents' knowledge: being in the 35-49-year age group (P-value = 0.042), those who had children themselves (P-value = 0.002) and those who had previous experience with trauma (P-value = 0.049). There was no correlation between the demand for further education in dental trauma and knowledge score. The knowledge regarding management of traumatic dental injuries in a group of teachers in the Tel-Aviv area is inadequate. Educational programs as well as addition to the curriculum are necessary to improve their emergency management of traumatic dental injuries and provide better protection to the students. © 2011 John Wiley & Sons A/S.

Full text: Prolonged air leakage lasting 7 days or more is one of the most common complications in thoracic surgery. This complication may result in increased morbidity and prolonged hospital stay. Amnion allografts have been used to minimise this complication. The aim of our study was to evaluate the usefulness of human amnion grafts in the treatment of air leakage following thoracic surgery. Deep-frozen, radiation-sterilized (35 kGy) human amnion grafts prepared at the Central Tissue Bank in Warsaw (Poland) were used. Amnion allografts were applied to 69 patients who had surgery: 36 thoracotomies, and 33 rethoracotomies had been performed. During lung ventilation the air leakage sites were identified and covered by the amnion flap. Air leakage were evaluated during the postoperative period. Retrospectively we analysed air leakage duration in 170 thoracothomies and rethoracotomies without amnion transplantation. The separation of lung tissue and the liberation of pleural adhesions may be result in the lung and visceral pleura injury. Deep-frozen and radiation-sterilized human amnion is biocompatible, flexible, strong and airtight. It may be easily attached to the lung parenchyma and allows coverage of the area of the lung parenchyma deprived of the visceral pleura. The use of human amnion allografts is simple and safe. After treatment with amnion in 85% of the cases air leakage last less than 7 days, and only its traces were observed. Our results suggest that the human amnion grafts applied for the prevention of air leakage in lung surgery is a safe, simple and effective method. (Author)

Understanding co-occurrence in urban human mobility (i.e. people from two regions visit an urban place during the same time span) is of great value in a variety of applications, such as urban planning, business intelligence, social behavior analysis, as well as containing contagious diseases. In recent years, the widespread use of mobile phones brings an unprecedented opportunity to capture large-scale and fine-grained data to study co-occurrence in human mobility. However, due to the lack of systematic and efficient methods, it is challenging for analysts to carry out in-depth analyses and extract valuable information. In this paper, we present TelCoVis, an interactive visual analytics system, which helps analysts leverage their domain knowledge to gain insight into the co-occurrence in urban human mobility based on telco data. Our system integrates visualization techniques with new designs and combines them in a novel way to enhance analysts' perception for a comprehensive exploration. In addition, we propose to study the correlations in co-occurrence (i.e. people from multiple regions visit different places during the same time span) by means of biclustering techniques that allow analysts to better explore coordinated relationships among different regions and identify interesting patterns. The case studies based on a real-world dataset and interviews with domain experts have demonstrated the effectiveness of our system in gaining insights into co-occurrence and facilitating various analytical tasks.

Full Text Available Leishmaniasis is an important metazoonosis caused by protozoa of the genus Leishmania and has a heteroxenic life cycle involving invertebrate and vertebrate hosts. Transmission occurs during the blood meal of infected phlebotomine sand flies in wild species, domestic animals, and humans. The dog is a reservoir for the parasite causing visceral leishmaniasis (VL, whereas in American tegumentary leishmaniasis (ATL, dogs are erratic hosts that are accidentally infected, as in humans. Dogs are considered an important indicator of the parasite and its vectors in the environment, thus highlighting the importance of diagnosis in these animals. This study aimed to assess the seroepidemiology of Leishmania spp. in dogs in the municipality of Telêmaco Borba that were part of a castration campaign. Blood samples from 191 dogs were collected, and their owners were surveyed on various epidemiological variables. Serological analysis was performed using indirect immunofluorescence (IIF and rapid immunochromatography (DPP®. Screening by IIF identified 13 (6.81% positive animals, none of which were positive for the DPP® test, which is specific for VL. Statistical analysis of the questionnaire responses indicated a significant association between seropositivity and the presence of stacked or composting leaves in the backyard (p = 0.0498, forest areas (squares, woods, parks near the residence (p = 0.0015, and poorly healing ulcerated or nodular epidermal lesions in the dog (p = 0.0138. This study revealed the presence of anti-Leishmania spp. IgG antibodies in dogs residing in Telêmaco Borba, suggesting the presence of the parasite and vector in the environment. In addition, the existence of stacked or composting leaves in the backyard, forest areas near the residence, and epidermal lesions in dogs are factors associated with Leishmania spp. infection in pet dogs.

Sato, Masaaki

1993-01-01

The present invention provides an air conditioner which can prevent an undesirable effects on a human body due to radon daughter nuclides in a closed space. That is, the concentration of the radon daughter nuclides in the air in the closed space is continuously measured. A necessary amount of ventilation air is determined based on the measured concentration to generate control signals. External air is introduced into the closed space by the generated control signals. With such procedures, necessary amount of external air is taken from the atmospheric air which can be regarded to have the radon daughter nuclide concentration substantially at zero, thereby enabling to reduce the concentration of the radon daughter nuclides in the closed space. As a result, undesired effects on the human body due to the radon daughter nuclides staying in the closed space can be prevented. According to simulation, the radon daughter nuclides are rapidly decreased only by ventilation only for three times or so in one hour. Accordingly, ventilation is extremely effective and convenient means as a countermeasure for the radon daughter nuclides. (I.S.)

Pollution prevention at ports: clearing the air

International Nuclear Information System (INIS)

Bailey, Diane; Solomon, Gina

2004-01-01

Seaports are major hubs of economic activity and of environmental pollution in coastal urban areas. Due to increasing global trade, transport of goods through ports has been steadily increasing and will likely continue to increase in the future. Evaluating air pollution impacts of ports requires consideration of numerous sources, including marine vessels, trucks, locomotives, and off-road equipment used for moving cargo. The air quality impacts of ports are significant, with particularly large emissions of diesel exhaust, particulate matter, and nitrogen oxides. The health effects of these air pollutants to residents of local communities include asthma, other respiratory diseases, cardiovascular disease, lung cancer, and premature mortality. In children, there are links with asthma, bronchitis, missed school days, and emergency room visits. The significance of these environmental health impacts requires aggressive efforts to mitigate the problem. Approaches to mitigation encompass a range of possibilities from currently available, low-cost approaches, to more significant investments for cleaner air. Examples of the former include restrictions on truck idling and the use of low-sulfur diesel fuel; the latter includes shore-side power for docked ships, and alternative fuels. A precautionary approach to port-related air pollution would encourage local production of goods in order to reduce marine traffic, greener design for new terminals, and state-of-the art approaches to emissions-control that have been successfully demonstrated at ports throughout the world

Overinvested with meaning, the forenames of the three protagonists, all products of the African diaspora, reveal something of their past lives and their destinies. The lack of a surname also testifies to their deracination, sought after or suffered. The « intimate drama » of these drifters, which flirts with madness, even, is expressed in part by the issue of naming, enabling the writer to speak of the difficulty of inhabiting a «black skin» today, but above all revealing the impossibility of defining any identity.

Improving retention in prevention of mother to child transmission (PMTCT) of HIV programs is critical to optimize maternal and infant health outcomes, especially now that lifelong treatment is immediate regardless of CD4 cell count). The WelTel strategy of using weekly short message service (SMS) to engage patients in care in Kenya, where mobile coverage even in poor areas is widespread has been shown to improve adherence to antiretroviral therapy (ART) and viral load suppression among those on ART. The aim of this study is to determine the effect of the WelTel SMS intervention compared to standard care on retention in PMTCT program in Kenya. WelTel PMTCT is a four to seven-centers, two-arm open randomized controlled trial (RCT) that will be conducted in urban and rural Kenya. Over 36 months, we plan to recruit 600 pregnant women at their first antenatal care visit and follow the mother-infant pair until they are discharged from the PMTCT program (when infant is aged 24 months). Participants will be randomly allocated to the intervention or control arm (standard care) at a 1:1 ratio. Intervention arm participants will receive an interactive weekly SMS 'How are you?' to which they are supposed to respond within 24 h. Depending on the response (ok, problem or no answer), a PMTCT nurse will follow-up and triage any problems that are identified. The primary outcome will be retention in care defined as the proportion of mother-infant pairs coming for infant HIV testing at 24 months from delivery. Secondary outcomes include a) adherence to WelTel; (b) adherence to antiretroviral medicine; (c) acceptance of WelTel and (d) cost-effectiveness of the WelTel intervention. This trial will provide evidence on the effectiveness of mHealth for PMTCT retention. Trial results and the cost-effectiveness evaluation will be used to inform policy and potential scale-up of mHealth among mothers living with HIV. ISRCTN98818734 ; registered on 9th December 2014.

Improving the quality of our environment has become a growing concern in this country and around the globe. Research efforts in this field have recently been accelerated by the passage of the 1990 Clean Air Act. This book reports on a symposium that is part of a continuing series on the surface science of catalysis. Including stationary and mobile source chapters alike in one volume allows the reader to note the similarities and differences between the two fields and possibly to apply ideas from one area to the other. The coverage is not intended to be exhaustive but rather to serve as a survey of some of the most current topics of interest in this field. The intended audience for this book is the chemist or engineer interested in pollution control, or prevention, or both in the automotive, chemical, petroleum, and other industries, or otherwise involved in the environmental applications of catalysts

Pollution prevention incentives and disincentives created by the Clean Air Act

International Nuclear Information System (INIS)

Webb, C.F.; Wolffe, G.S.

1998-01-01

Environmental laws and regulations have not always been implemented in a manner that allows for the consideration of pollution prevention (P2) alternatives as a means of achieving progress toward air quality goals. Recently, the US Environmental Protection Agency (EPA) has been making strides to reinterpret laws and regulations to be more flexible and encourage P2 projects that do not involve end-of-the-pipe controls. For instance, when conducting control technology evaluations such as best available control technology (BACT) and lowest achievable emission rate (LAER), facilities can and should take into consideration P2 options that accomplish the same emission reduction goals as traditional end-of-the-pipe controls. There are also new emissions trading provisions building on those allowed in the acid rain and offset trading programs that promise to make P2 projects much more cost-effective. Several traditional 'command-and-control' programs of the Clean Air Act (CAA) also promote P2 projects. For instance, emission reductions realized through P2 projects show managers a direct cost savings due to reductions in Title V facility annual emissions fees and possibly a direct cost benefit through sale of emission credits. Furthermore, the CAA encourages P2 indirectly through the detail understanding of processes gained from emissions inventories and risk management plans (RMPs). However, many CAA prescriptive programs create disincentives for industry to select P2 alternatives. 30 refs

Epidemiological study of air filtration systems for preventing PRRSV infection in large sow herds.

Science.gov (United States)

Alonso, Carmen; Murtaugh, Michael P; Dee, Scott A; Davies, Peter R

2013-10-01

Porcine reproductive and respiratory syndrome virus (PRRSV) is the most economically significant pathogen in the US swine industry. Aerosol transmission among herds is a major concern in pig dense regions and filtration of incoming air, in combination with standard biosecurity procedures, has been demonstrated to prevent transmission of PRRSV into susceptible herds. To quantify the impact of air filtration on reducing risk of PRRSV outbreaks, we compared the incidence rate of new PRRSV introductions in 20 filtered and 17 non-filtered control sow herds in a swine dense region of North America during a 7 year study period. Events of novel virus introduction were ascertained by phylogenetic analysis of PRRSV ORF5 gene sequences. Putative new viruses were defined as exogenous (introduced) based on ORF5 nucleotide sequence differences compared to previous farm isolates. The influence of sequence difference cut-off values ranging from 2 to 10% on case definition and relative risk were evaluated. Non-filtered farms incurred about 0.5 outbreaks per year, with a seasonal increase in risk in cooler periods. Baseline risk, prior to filtration, in treatment farms was approximately 0.75 per year, approximately 50% higher than in control farms. Air filtration significantly reduced risk of PRRSV introduction events to 0.06-0.22 outbreaks per year, depending on the cut-off values used to classify a virus isolate as new to the herd. Overall, air filtration led to an approximately 80% reduction in risk of introduction of novel PRRSV, indicating that on large sow farms with good biosecurity in swine-dense regions, approximately four-fifths of PRRSV outbreaks may be attributable to aerosol transmission.

The aims of this study were to identify, assess, and summarise available evidence about the effectiveness of static air mattress overlays to prevent pressure ulcers. The primary outcome was the incidence of pressure ulcers. Secondary outcomes included costs and patient comfort. This study was a systematic review. Six electronic databases were consulted: Cochrane Library, EMBASE, PubMed (Medline), CINAHL (EBSCOhost interface), Science direct, and Web of Science. In addition, a hand search through reviews, conference proceedings, and the reference lists of the included studies was performed to identify additional studies. Potential studies were reviewed and assessed by 2 independent authors based on the title and abstract. Decisions regarding inclusion or exclusion of the studies were based on a consensus between the authors. Studies were included if the following criteria were met: reporting an original study; the outcome was the incidence of pressure ulcer categories I to IV when using a static air mattress overlay and/or in comparison with other pressure-redistribution device(s); and studies published in English, French, and Dutch. No limitation was set on study setting, design, and date of publication. The methodological quality assessment was evaluated using the Critical Appraisal Skills Program Tool. Results were reported in a descriptive way to reflect the exploratory nature of the review. The searches included 13 studies: randomised controlled trials (n = 11) and cohort studies (n = 2). The mean pressure ulcer incidence figures found in the different settings were, respectively, 7.8% pressure ulcers of categories II to IV in nursing homes, 9.06% pressure ulcers of categories I to IV in intensive care settings, and 12% pressure ulcers of categories I to IV in orthopaedic wards. Seven comparative studies reported a lower incidence in the groups of patients on a static air mattress overlay. Three studies reported a statistical (P pressure ulcers. There

The Agricultural Landscape of Tel Burna: Ecology and Economy of a Bronze Age/Iron Age Settlement in the Southern Levant

2017-12-01

Full Text Available The Shephelah, known as the breadbasket of the southern Levant, is one of the more extensively investigated regions of the southern Levant in terms of archaeobotanical research. However, studies dealing with agriculture are scarce in comparison to the archaeobotanical data available. The analysis of the archaeobotanical assemblage in combination with the archaeological remains from Tel Burna will contribute to the investigation of the agriculture of the Shephelah. Several seasons of excavation revealed a cultic complex dating to the Late Bronze Age and an Iron Age II settlement with various agricultural installations such as silos and wine or olive presses. In this paper, we present the agricultural features in conjunction with the systematical archaeobotanical sampling, which enables us to reconstruct the types of crop plants cultivated at the site. Grass pea seeds dominate the assemblage collected from the Late Bronze Age complex, which may point to a connection to the Aegean. The Iron Age assemblage is distinguished by a significantly broad range of crop plants which were cultivated in vicinity of the tell. The archaeological Iron Age remains indicate that the processing of secondary products such as olive oil, wine, or textiles took place within the Iron Age settlement of Tel Burna. This first comprehensive overview describes the character of agricultural production in the Late Bronze Age to Iron Age environmental and geopolitical transformations.

A pressure ulcer is one of the most important concerns for wheelchair bound patients with spinal cord injuries. A pressure ulcer is a localized injury near the buttocks that bear ischial tuberosity oppression over a long period of time. Due to elevated compression to blood vessels, the surrounding tissues suffer from a lack of oxygen and nutrition. The ulcers eventually lead to skin damage followed by tissue necrosis. The current medical strategy is to minimize the occurrence of pressure ulcers by regularly helping patients change their posture. However, these methods do not always work effectively or well. As a solution to fundamentally prevent pressure ulcers, a smart air cushion system was developed to detect and control pressure actively. The air cushion works by automatically adjusting a patient's sitting posture to effectively relieve the buttock pressure. To analyze the correlation between the dynamic pressure profiles of an air cell with a patient's weight, a projection Moiré system was adopted to measure the deformation of an air cell and its associated stress distribution. Combining a full-field deformation imaging with air pressure measured within an air cell, the patient's weight and the stress distribution can be simultaneously obtained. By integrating a full-field optical metrology with a time varying pressure sensor output coupled with different active air control algorithms for various designs, we can tailor the ratio of the air cells. Our preliminary data suggests that this newly developed smart air cushion has the potential to selectively reduce localized compression on the tissues at the buttocks. Furthermore, it can take a patient's weight which is an additional benefit so that medical personnel can reference it to prescribe the correct drug dosages.

Indoor air quality

International Nuclear Information System (INIS)

Hollowell, C.D.

1981-06-01

Rising energy prices, among other factors, have generated an incentive to reduce ventilation rates and thereby reduce the cost of heating and cooling buildings. Reduced ventilation in buildings may significantly increase exposure to indoor air pollution and perhaps have adverse effects on occupant health and comfort. Preliminary findings suggest that reduced ventilation may adversely affect indoor air quality unless appropriate control strategies are undertaken. The strategies used to control indoor air pollution depend on the specific pollutant or class of pollutants encountered, and differ somewhat depending on whether the application is to an existing building or a new building under design and construction. Whenever possible, the first course of action is prevention or reduction of pollutant emissions at the source. In most buildings, control measures involve a combination of prevention, removal, and suppression. Common sources of indoor air pollution in buildings, the specific pollutants emitted by each source, the potential health effects, and possible control techniques are discussed

This paper aims to investigate environmental aspects from different iron and steel production processes. A methodology based on material flows is developed in order to verify some air emission levels attained by Pollution Control and Pollution Prevention alternatives. The data basis for modeling energy and materials flows in iron and steel production is obtained from a literature review on different technological processes, energy and materials consumption and pollutant releases to the environmental Modeling combines both process analysis and input-output techniques to simulate the different iron and steel production routes and to estimate the resulting total atmospheric pollution releases based on air emission factors for several pollutants by each production step. Processes examined include: (1) Conventional Integrated (100% ore-based and partly scrap-based); (2) Mini-mill with EAF (100% scrap-based and partly DRI-based); and (3) New Integrated based on the COREX smelting reduction process. Among the alternatives considered for air emissions reductions are those related to Pollution Control (mainly gas cleaning systems) and to Pollution Prevention (change/reduction in input materials, operational procedures and housekeeping improvements, on-site recycling and technology innovations and modifications). Results indicate higher air pollution intensity for the Conventional Integrated Route over the Mini-mill with EAF and COREX smelting reduction processes, though pointing out that final figures are strongly affected by the systems' boundaries and the different air emission levels of each production step

Corrosion on air preheaters and economisers; Korrosion hos luftfoervaermare och ekonomisrar

2012-05-15

Combustion plants in Sweden are exposed to considerable stress regarding low temperature corrosion, and failures due to low temperature corrosion occur regularly. Particularly common is corrosion problems connected to air preheaters and economisers. The number of combustion plants having air preheaters and economisers is however large, and the result of a collection of experiences regarding corrosion on air preheaters and economisers therefore has the potential to give a broad knowledge base. The summary of collection of experiences that has been done here, complemented with a literature survey, is expected to give plant owners and plant constructors a valuable tool to prevent corrosion on the flue gas side of air preheaters and economisers. The choice of plants for the inquiry was made using a list from the Swedish Naturvaardsverket (Environmental Protection Agency) indicating the emissions of NO{sub x}gases from Swedish combustion plants. From that list mainly the plants with the largest emissions were chosen, resulting in a number of 30 plants. Depending on that most of the plants have several boilers, and that the connected tubes often have several economisers and air preheaters, the number of economisers and air preheaters in this experience collection is at least 85. The study was however not limited to economisers and air preheaters, but also experiences connected to corrosion of other units were collected when mentioned, and the most interesting information here is also included in the report. Also a number of the plants were visited to improve the basis of the report, e.g. by photographing the most interesting parts. As the insight of the extension of the problem increased, renewed interview rounds were made, and the last one was made in August 2011.

Full Text Available This work has the objectives of testing and systematizing the methodological proposal of photography as a discharger of the trigger of memory, a technique that combines photographic images with oral history. The method, developed by the group Communication and History of Universidade Estadual de Londrina, was formalized in the dissertation of Maria Luisa Hoffmann (2010 and, since then, it has been applied to cities with recent histories. To do a relevant test in this dissertation, Telêmaco Borba(PR was chosen as field of study, and the precepts of empiricism in communication were respected, following the ideas of Maria Immacolata Vassallo Lopes (2010 and Luiz Claudio Martino (2010. The application of the method was also based theoretically, using as references the works of Jacques Le Goff (2003, Ecléa Bosi (2009 and Boris Kossoy (2009. During the empirical process, nine pioneers of Telêmaco Borba were submitted to the methodological proposal, using 17 old photographs of the city. Roughly, the results of the test show that the technique, when applied with the epistemological criteria of science, becomes an efficient empirical tool, capable of bringing new data and information to the studies of memory and to the history of the studied cities.

Full Text Available Los telómeros son estructuras complejas de ADN y proteína localizadas en el extremo de los cromosomas eucariotes. Su principal función es proteger el extremo cromosomal de ser reconocido y procesado como ADNs fracturado, evitando así eventos de recombinación y fusión que conducen a inestabilidad cromosomal. El ADN telomérico consta de secuencias cortas, repetidas una tras otra, ricas en guanina; la cadena rica en guanina se extiende formando una región de cadena sencilla denominada extremo 3´ protuberante. Las proteínas por su parte, se pueden clasificar en: dsBPs, o proteínas de unión a la cadena doble, GBPs aquellas que reconocen específicamente el extremo protuberante y, proteínas que las interconectan mediante interacciones proteína-proteína. El gen PF3D7_1006800 de Plasmodium falciparum codifica para una proteína putativa similar a una GBP de Criptosporidium parvum, con el fin de establecer si esta proteína de P. falciparum presenta la capacidad de unión al ADN telomérico del parásito, se produjo una proteína recombinante a partir de la región codificante del gen, se purificó y se utilizó en ensayos de unión a ADN, y en la generación de anticuerpos policlonales específicos contra PfGBP. Nuestros resultados indican que la proteína de P. falciparum es una proteína nuclear con capacidad de unión al ADN telomérico in vitro, por lo que podría ser parte del complejo proteico encargado de proteger y/o mantener el telómero in vivo.

Traditionally, the healthcare industry has been no stranger to some conflicts of interest. However, as healthcare responds to demands to contain costs and adapts business models that resemble those of the corporate world, new conflicts of interest arise. Nurse executives operating in healthcare systems today must have an understanding of conflicts of interest in order to promptly identify actual as well as potential conflicts. It is imperative that strategies are set in place to prevent or handle conflicts of interest as they occur in order to build trusting relationships with patients, suppliers, and communities.

Air pollution control policy in Switzerland

Energy Technology Data Exchange (ETDEWEB)

Leutert, G. [Forests and Landscape, Berne (Switzerland). Federal Office of Environment

1995-12-31

The legal basis of the Swiss air pollution control policy is set by the Federal Law on the Protection of the Environment, which came into force in 1985. It aims to protect human beings, animals and plants, their biological communities and habitats against harmful effects or nuisances and to maintain the fertility of the soil. The law is source-oriented (by emission standards) as well as effect-oriented (by ambient air quality standards). To link both elements a two-stage approach is applied. In the first stage preventive measures are taken at the emitting sources, irrespective of existing air pollution levels. Emissions have to be limited by early preventive measures as much as technical and operational conditions allow and as far as economically acceptable (prevention principle). By this, air pollution shall be kept as low as possible as a matter of principle, without the environment having to be in danger first. In a second stage the measures are strengthened or backed up by additional measures if ambient air quality standards laid down in the Ordinance on Air Pollution Control are exceeded. At this second stage, protection of man and his environment has priority over economic considerations. (author)

Pch2 acts through Xrs2 and Tel1/ATM to modulate interhomolog bias and checkpoint function during meiosis.

Directory of Open Access Journals (Sweden)

Hsuan-Chung Ho

2011-11-01

Full Text Available Proper segregation of chromosomes during meiosis requires the formation and repair of double-strand breaks (DSBs to form crossovers. Repair is biased toward using the homolog as a substrate rather than the sister chromatid. Pch2 is a conserved member of the AAA(+-ATPase family of proteins and is implicated in a wide range of meiosis-specific processes including the recombination checkpoint, maturation of the chromosome axis, crossover control, and synapsis. We demonstrate a role for Pch2 in promoting and regulating interhomolog bias and the meiotic recombination checkpoint in response to unprocessed DSBs through the activation of axial proteins Hop1 and Mek1 in budding yeast. We show that Pch2 physically interacts with the putative BRCT repeats in the N-terminal region of Xrs2, a member of the MRX complex that acts at sites of unprocessed DSBs. Pch2, Xrs2, and the ATM ortholog Tel1 function in the same pathway leading to the phosphorylation of Hop1, independent of Rad17 and the ATR ortholog Mec1, which respond to the presence of single-stranded DNA. An N-terminal deletion of Xrs2 recapitulates the pch2Δ phenotypes for signaling unresected breaks. We propose that interaction with Xrs2 may enable Pch2 to remodel chromosome structure adjacent to the site of a DSB and thereby promote accessibility of Hop1 to the Tel1 kinase. In addition, Xrs2, like Pch2, is required for checkpoint-mediated delay conferred by the failure to synapse chromosomes.

Review of studies about epidemiological and physiopathological knowledge of ambient air particles short-term cardio-vascular effects. CURRENTS AND STRONG POINTS: Many studies, in contrasted countries for pollution's sources, meteorological conditions or socio-demographical characteristics, have shown health effects due to ambient air particles. After having studied mainly the respiratory effects of particulate air pollution, epidemiologists are now interested in the cardio-vascular effects of ambient air particles. In fact, serious effects seem to exist in fragile people which can get to emergency department visits, hospitalisation and even death. In addition, studies have shown less serious effects, but likely to be frequent (cardiac symptoms, and stoppages for cardio-vascular causes, notably). The exact mechanism by which particles have cardio-vascular adverse health effects is unknown, but experimental and epidemiological studies have led to several hypotheses: local pulmonary effects seem to be followed by systemic effects, which would be responsible for effects on the electrical activity of the heart through cardiac autonomic dysfunction and effects on the blood supply to the heart. The objective of this work is to summarise epidemiological and physiopathological knowledge about the cardio-vascular effects of ambient air particles. To evaluate the real importance of cardio-vascular effects due to particulate air pollution and to identify their exact mechanism, a more precise knowledge of detailed causes of deaths and hospitalisations and a better knowledge of less serious effects, but likely to be frequent, is necessary. Equally, a detailed identification of fragile people is essential for developing preventive actions.

Evaporation-preventive device for nuclear reactor pool water

International Nuclear Information System (INIS)

Kurusu, Yoshihisa; Akabori, Shiro.

1986-01-01

Purpose: To prevent pool water from evaporating by a great amount in a reactor pool such as a spent fuel storing pool. Constitution: Air discharge and in-take ports are disposed just above the surface of the pool water and charge and discharge of airs are forcively carried out to form air curtains above the pool water. Water vapor evaporated from the surface of the pool water does not diffuse above the air curtains due to the air stream of the curtains, but is intaken into the intake port and then condensated into water by a steam condensator and re-supplied to the pool. Since diffusion of water vapor and radioactive materials are suppressed above the air curtains, the working circumstance in the pool chamber can be maintained desirably thereby keeping the radioactivity dose in the atmosphere. Further, incorporation of dusts from above into the pool can also be prevented by the air curtains to provide an effect for the prevention of radioactive contamination. Further, since covers are not used, visual observation can be insured. (Kawakami, Y.)

Application of multivariate statistical methods to classify archaeological pottery from Tel-Alramad site, Syria, based on x-ray fluorescence analysis

Bakraji, E. H.

2007-01-01

Radioisotopic x-ray fluorescence (XRF) analysis has been utilized to determine the elemental composition of 55 archaeological pottery samples by the determination of 17 chemical elements. Fifty-four of them came from the Tel-Alramad Site in Katana town, near Damascus city, Syria, and one sample came from Brazil. The XRF results have been processed using two multivariate statistical methods, cluster and factor analysis, in order to determine similarities and correlation between the selected samples based on their elemental composition. The methodology successfully separates the samples where four distinct chemical groups were identified. (author)

In the past decade, there have been exciting developments in the field of lithium ion batteries as energy storage devices, resulting in the application of lithium ion batteries in areas ranging from small portable electric devices to large power systems such as hybrid electric vehicles. However, the maximum energy density of current lithium ion batteries having topatactic chemistry is not sufficient to meet the demands of new markets in such areas as electric vehicles. Therefore, new electrochemical systems with higher energy densities are being sought, and metal-air batteries with conversion chemistry are considered a promising candidate. More recently, promising electrochemical performance has driven much research interest in Li-air and Zn-air batteries. This review provides an overview of the fundamentals and recent progress in the area of Li-air and Zn-air batteries, with the aim of providing a better understanding of the new electrochemical systems.

2010-02-01

TERMINAL EAR1-like (TEL) genes encode putative RNA-binding proteins only found in land plants. Previous studies suggested that they may regulate tissue and organ initiation in Poaceae. Two TEL genes were identified in both Populus trichocarpa and the hybrid aspen Populus tremula x P. alba, named, respectively, PoptrTEL1-2 and PtaTEL1-2. The analysis of the organisation around the PoptrTEL genes in the P. trichocarpa genome and the estimation of the synonymous substitution rate for PtaTEL1-2 genes indicate that the paralogous link between these two Populus TEL genes probably results from the Salicoid large-scale gene-duplication event. Phylogenetic analyses confirmed their orthology link with the other TEL genes. The expression pattern of both PtaTEL genes appeared to be restricted to the mother cells of the plant body: leaf founder cells, leaf primordia, axillary buds and root differentiating tissues, as well as to mother cells of vascular tissues. Most interestingly, PtaTEL1-2 transcripts were found in differentiating cells of secondary xylem and phloem, but probably not in the cambium itself. Taken together, these results indicate specific expression of the TEL genes in differentiating cells controlling tissue and organ development in Populus (and other Angiosperm species).

Reuter, T.D.; Kirchhuebel, H.; Dahlgruen, H.D.

1976-01-01

Pulmonary distribution of ventilation was assessed in ten patients with COPD on the basis of defined regions of interest. Areas of hypeventilation are demarcated on the basis of the trapped air scintigram corrected for lung volume. After the demarcations are transfered to the scintigram of fractional exchange of air the regional VI is computed and compared with normal values. The detectability of regional ventilation disturbances was found to be improved compared to a subdivision scheme of six regions of interest

“A source of satisfaction to all Jews, wherever they may be living”. Louis Miller between New York and Tel Aviv, 1911

Full Text Available Although throughout the middle-ages Jews used to live in urban environment more than non-Jews, urbanization process in the 19th century was as critical to Jewish modern history as in other cases. Modernization, in all aspects, had a deep impact on Jewish demography, socio-economic life and self understanding. On the same time Jews were immigrating by the millions to the “new world” (mainly to the United States, a small current of Jews was heading to Palestine (Eretz Israel if to use their specific term. As opposed to a common understanding of Zionism, the future city and the neo-urbanization of the Jews – and not only the new villages (Moshavot, Kibbutzim, Moshavim – was a main Zionist goal. This article describes one of the first comprehensive observations of these issues, as seen from the eyes of Louis Miller, himself a Jewish immigrant that settled in the outmost city of the modern world: New York. In 1911 he paid a visit to the one-year-old Tel Aviv, and managed to see in this new modest garden-city the cradle of the Zionist revolution. Not less important: Miller understood as early as 1911, the crucial role Jewish settlements in Palestine would have in the crystallization of modern Jewish peoplehood. Tel Aviv took major part in this development. It still does.

A Low Cost Air Hybrid Concept Un concept hybride à air et à bas prix

Directory of Open Access Journals (Sweden)

Lee C. Y.

2010-02-01

Full Text Available The air hybrid engine absorbs the vehicle kinetic energy during braking, stores it in an air tank in the form of compressed air, and reuses it to propel a vehicle during cruising and acceleration. Capturing, storing and reusing this braking energy to give additional power can therefore improve fuel economy, particularly in cities and urban areas where the traffic conditions involve many stops and starts. In order to reuse the residual kinetic energy, the vehicle operation consists of 3 basic modes, i.e. Compression Mode (CM, Expander Mode (EM and normal firing mode. Unlike previous works, a low cost air hybrid engine has been proposed and studied. The hybrid engine operation can be realized by means of production technologies, such as VVT and valve deactivation. In this work, systematic investigation has been carried out on the performance of the hybrid engine concept through detailed gas dynamic modelling using Ricardo WAVE software. Valve timing optimization has been done for the more efficient operation of air hybrid operation and obtaining higher braking and motoring mean effective pressure for CM and EM respectively. Le moteur hybride à air absorbe l’énergie cinétique du véhicule en cas de freinage, la stocke sous forme d’air comprimé, puis la réutilise pour faire avancer le véhicule en circulation ou en accélération. Capter, stocker et réutiliser cette énergie et créer ainsi une puissance plus importante peut donc permettre de plus grandes économies de carburant, surtout en ville et zone urbaine, lorsque les conditions de circulation imposent de nombreux arrêts et démarrages. Pour pouvoir réutiliser l’énergie cinétique, on distingue trois modes de base d’utilisation du véhicule : les modes compression (MC, expansion (ME et standard. Un moteur hybride à air et à bas prix a été proposé et étudié. Un tel moteur peut être opéré par le biais de technologies de production, comme le VVT et la d

Horch, K; Wirz, J

2005-11-01

Well-informed citizens and patients regard health policy innovations as a key element when it comes to reforms in the health service--both in health economics and with regard to prevention issues. We evaluated the data provided by the 2003 Telephone Health Survey (GSTel03) to examine demographic and social distinctions in the use of different information sources. At the same time we examined whether there are any population-related differences in people's interest in health information depending on their levels of health awareness, attitudes to prevention and related modes of behaviour. The data generated by the survey show that there is considerable interest in health-related topics. Only 2% of the people questioned used no information sources for this purpose. In addition to more traditional media (books, newspapers, information from pharmacies), information provided by health insurance companies and via the Internet is becoming increasingly important. With the exception of the Internet, all other sources of information are used more frequently by women than by men, and demand for most of the information media increases with age. The frequency of information use and the number of different media used increase from the lower to the upper strata of society. As far as selected variables of health-related behaviour are concerned (smoking, sport, alcohol), the results show a link between a more positive attitude to health and a greater interest in information.

Preventing freezing of condensate inside tubes of air cooled condenser

International Nuclear Information System (INIS)

Joo, Jeong A; Hwang, In Hwan; Lee, Dong Hwan; Cho, Young Il

2012-01-01

An air cooled condenser is a device that is used for converting steam into condensate by using ambient air. The air cooled condenser is prone to suffer from a serious explosion when the condensate inside the tubes of a heat exchanger is frozen; in particular, tubes can break during winter. This is primarily due to the structural problem of the tube outlet of an existing conventional air cooled condenser system, which causes the backflow of residual steam and noncondensable gases. To solve the backflow problem in such condensers, such a system was simulated and a new system was designed and evaluated in this study. The experimental results using the simulated condenser showed the occurrence of freezing because of the backflow inside the tube. On the other hand, no backflow and freezing occurred in the advanced new condenser, and efficient heat exchange occurred

The device of the present invention comprises a heater for heating pressurized air and a moisturizer for mixing steams with the pressurized air heated by the heater to make moisturized pressurized air. Steams are mixed to rise humidity by the moisturizing up to the saturated vapor pressure at the temperature of the heating by heating pressurized air as an object of moisturizing by the heater to prevent dew condensation while increasing the amount of steams to be mixed. With such procedures, moisture enriched pressurized air can be jetted out thereby enabling to prevent deposition of solid materials and crystallized materials of gaseous wastes. (T.M.)

The Cultural Adaptation of a Community-Based Child Maltreatment Prevention Initiative.

Science.gov (United States)

McLeigh, Jill D; Katz, Carmit; Davidson-Arad, Bilha; Ben-Arieh, Asher

2017-06-01

A unique primary prevention effort, Strong Communities for Children (Strong Communities), focuses on changing attitudes and expectations regarding communities' collective responsibilities for the safety of children. Findings from a 6-year pilot of the initiative in South Carolina have shown promise in reducing child maltreatment, but efforts to adapt the initiative to different cultural contexts have been lacking. No models exist for adapting an initiative that takes a community-level approach to ensuring children's safety. Thus, this article addresses the gap by providing an overview of the original initiative, how the initiative was adapted to the Israeli context, and lessons learned from the experience. Building on conceptualizations of cultural adaptation by Castro et al. (Prevention Science, 5, 2004, 41) and Resnicow et al. (Ethnicity and Disease, 9, 1999, 11), sources of nonfit (i.e., sociodemographic traits, political conflict, government services, and the presence and role of community organizations) were identified and deep and surface structure modifications were made to the content and delivery. Ultimately, this article describes the adaption and dissemination of a community-based child maltreatment prevention initiative in Tel Aviv, Israel, and addresses researchers' calls for more publications describing the adaptation of interventions and the procedures that need to be implemented to achieve cultural relevance. © 2015 Family Process Institute.

Stay the Night: Meera Margaret Singh at the Gladstone Hotel Stay the Night : Meera Margaret Singh à l’hôtel Gladstone

Directory of Open Access Journals (Sweden)

Kerry Manders

2012-07-01

Full Text Available This essay examines Meera Margaret Singh’s exhibition Nightingale in the time and place of the liminal space we call “hotel.” In intertexual dialogue with Wayne Koestenbaum’s Hotel Theory, the author not only reviews Singh’s intimate photographs of her mother, she reads the images with and against the architecture in which they are exhibited. The Gladstone as exhibition space redoubles Singh’s emphasis on the tense connectivity of apparent binaries: youth and age, public and private, artist and model, object and spectator, living and dying. The quotidian activities of hotel living—guests’ arrivals, departures, and returns—become inextricable pieces of Singh’s site-specific installation. The author theorizes what Freud calls the “foretaste of mourning” in this work, grappling with what will be but is not yet the death of the mother. Singh’s Nightingale proposes that we do not “work through” mourning: mourning is a perpetual way of being in the present.Cet article examine l’exposition photographique de Meera Margaret Singh dans l’espace liminal qu’est l’hôtel. En dialogue intertextuel avec l’œuvre de Wayne Koestenbaum, Hotel Theory, l’auteur examine les portraits intimes de la mère de la photographe, tout en les lisant en fonction de l’architecture de leur emplacement. L’hôtel Gladstone en tant que lieu d’exposition redouble donc l’accent que met la photographe sur les liens tendus des systèmes binaires apparents: la jeunesse et l’âge ; le public et le privé ; l’artiste et le modèle ; l’objet et le spectateur; vivre et mourir. Les activités quotidiennes de la vie en hôtel – l’arrivée, le départ, et le retour d’invités – deviennent des éléments inextricables de l’œuvre in situ. L’auteur théorise le concept de Freud sur l’avant-goût du deuil, explorant ce qui deviendra mais ne l’est pas encore : la mort de la mère. Cette exposition propose que nous ne �

Patient engagement in care and adherence to medication are critical to achieving the full benefits of antiretroviral therapy (ART) among people with HIV infection. A randomized controlled trial in Kenya, WelTelKenya1, showed that an interactive mobile phone text-messaging intervention can improve adherence and viral load suppression. We conducted a pilot study to adapt the WelTel intervention for HIV-infected clients (n = 25) at an HIV clinic in Vancouver, British Columbia. Between April and June 2012, we recruited five participants from five groups: youth (14-24 years), mature (≥50 years), English as a second language, remote (≥3 hours travel time to clinic), and nonsuppressed (CD4+ T cell count <200 cells/mm(3) and viral load ≥250 copies/mL on two consecutive occasions). Participants described the intervention as a useful way to communicate with health care providers, thus increasing the ability to access services, report side effects, and attend appointments.

Potchter, Oded; Oz, Meirav; Brenner, Shmuel; Yaakov, Yaron; Schnell, Izhak

2014-12-01

Short-term personal exposure of passengers in different types of motor vehicles to carbon monoxide was investigated in an intensively used main road in Israel's Tel Aviv metropolitan area. According to monitoring stations of the Ministry for Environmental Protection (MEP), concentrations of carbon monoxide (CO) along the road, at a height of 3 m above pedestrian level, in the Tel Aviv metropolitan area, are currently very low. However, these measurements do not reflect the actual exposure of commuters, which were the main objective of this study. Four vehicle types/travel modes were investigated: private cars with closed windows, private cars with open windows, motorcycles, and buses. The commuter CO average exposure was the accumulative exposure divided by the duration of the sampling taken along the route, for each type of vehicles. The results showed that commuters in cars with closed windows were exposed to the highest mean CO level, 27.2 ppm, for a period of 38 min; those in a car with open windows, to 19.7 ppm for 38 min; motorcycle riders, to 12.8 ppm, for 17 min; and bus users were exposed to the lowest mean pollution level, of only 3.6 ppm, for 25 min. Thus, CO values of 1 to 3 ppm, as measured at an MEP adjacent monitoring station, may indicate the exposure to CO pollution of area residents, but do not represent the actual exposure of commuters on the congested main road.

[Social actors in HIV/AIDS prevention: opposition and interests in educational policy in Mexico, 1994-2000].

Science.gov (United States)

Granados-Cosme, José Arturo; Nasaiya, Kittipong; Brambila, Alberto Torres

2007-03-01

Studies and recommendations by health agencies have emphasized the importance of education in HIV-AIDS prevention. Mexico has included topics on sexuality and HIV-AIDS in school programs, triggering resistance by some social actors. The current study seeks to clarify the various positions and interests and their influence on the textbook content. A literature search was conducted on the period during which the last educational reform was implemented in Mexico. The discourse analysis focused on the ethnography of communication, which identified: the various actors' positions, arguments, actions, economic and political power, and relations to others. The results show that those who oppose the inclusion of these themes in the school curriculum base their position on tradition, contrary to modernization and secularization of social life, and that their positions range from refusal to raising conditions. Networks have been formed that provide such groups with significant economic and political power. Government has given in to some demands by partially modifying the textbook contents. The current analysis proposes to reflect on the potential repercussions of such actions on the control of the epidemic.

Reflexiones sobre la cuestión de la integración de los solicitantes de asilo en el Cantón de Neuchâtel

2016-10-01

Full Text Available El debate sobre la integración de los extranjeros en Suiza, país multicultural en sus raíces y orígenes, se mantiene en una constante tensión frente a las corrientes proteccionistas y a las tendencias patrióticas, comunes a muchos rincones del planeta. Esos «otros», extraños extranjeros, que actúan diferentemente, difíciles de situar en cualquier sector de la sociedad, generan inquietud entre los nativos. En el caso de los expatriados por razones políticas, el  estatus de refugiado o de solicitante de asilo político representa una tarjeta de identidad pesada de transportar consigo. Una visión simplista ubica al demandante de asilo en el eje de la criminalidad y del narcotráfico. Se ignora la individualidad de los casos, así como la violencia en la que el propio sistema y las leyes del asilo político los someten. Frente a una política federal estrictamente cerrada en lo que a integración del solicitante del asilo concierne, el Cantón de Neuchâtel, terreno de análisis de nuestra investigación, se da un espacio de debate en cuanto a la necesidad de implicar a este grupo, demandantes de asilo, dentro de su dinámica social. Diversos sectores de la sociedad de Neuchâtel se movilizan a fin de contrarrestar las insuficiencias del sistema. Sin embargo, los obstáculos son múltiples y se suceden. La investigación que presentamos a continuación tiene como finalidad analizar las diversas acciones que se desarrollan en el Cantón de Neuchâtel en favor de la integración del  sector en cuestión y el impacto de éstas sobre dicho grupo. Nos hemos propuesto hacer un seguimiento del camino que recorre el demandante de asilo, a través de las diversas instituciones, a fin de conocer los esfuerzos y los obstáculos de esta gestión.

Air bubbles and hemolysis of blood samples during transport by pneumatic tube systems.

Science.gov (United States)

Mullins, Garrett R; Bruns, David E

2017-10-01

Transport of blood samples through pneumatic tube systems (PTSs) generates air bubbles in transported blood samples and, with increasing duration of transport, the appearance of hemolysis. We investigated the role of air-bubble formation in PTS-induced hemolysis. Air was introduced into blood samples for 0, 1, 3 or 5min to form air bubbles. Hemolysis in the blood was assessed by (H)-index, lactate dehydrogenase (LD) and potassium in plasma. In an effort to prevent PTS-induced hemolysis, blood sample tubes were completely filled, to prevent air bubble formation, and compared with partially filled samples after PTS transport. We also compared hemolysis in anticoagulated vs clotted blood subjected to PTS transport. As with transport through PTSs, the duration of air bubble formation in blood by a gentle stream of air predicted the extent of hemolysis as measured by H-index (pair space in a blood sample prevented bubble formation and fully protected the blood from PTS-induced hemolysis (ptransport and was partially protected from hemolysis vs anticoagulated blood as indicated by lower LD (ptransport. Prevention of air bubble formation in blood samples during PTS transport protects samples from hemolysis. Copyright © 2017 Elsevier B.V. All rights reserved.

Conceptual Design of Portable Filtered Air Suction Systems For Prevention of Released Radioactive Gas under Severe Accidents of NPP

Energy Technology Data Exchange (ETDEWEB)

Gu, Beom W.; Choi, Su Y.; Yim, Man S.; Rim, Chun T. [Korea Advanced Institute of Science and Technology, Daejeon (Korea, Republic of)

2014-05-15

It becomes evident that severe accidents may occur by unexpected disasters such as tsunami, heavy flood, or terror. Once radioactive material is released from NPP through severe accidents, there are no ways to prevent the released radioactive gas spreading in the air. As a remedy for this problem, the idea on the portable filtered air suction system (PoFASS) for the prevention of released radioactive gas under severe accidents was proposed. In this paper, the conceptual design of a PoFASS focusing on the number of robot fingers and robot arm rods are proposed. In order to design a flexible robot suction nozzle, mathematical models for the gaps which represent the lifted heights of extensible covers for given convex shapes of pipes and for the covered areas are developed. In addition, the system requirements for the design of the robot arms of PoFASS are proposed, which determine the accessible range of leakage points of released radioactive gas. In this paper, the conceptual designs of the flexible robot suction nozzle and robot arm have been conducted. As a result, the minimum number of robot fingers and robot arm rods are defined to be four and three, respectively. For further works, extensible cover designs on the flexible robot suction nozzle and the application of the PoFASS to the inside of NPP should be studied because the radioactive gas may be released from connection pipes between the containment building and auxiliary buildings.

A theoretical model of air and steam co-injection to prevent the downward migration of DNAPLs during steam-enhanced extraction

Science.gov (United States)

Kaslusky, Scott F.; Udell, Kent S.

2002-04-01

When steam is injected into soil containing a dense volatile non-aqueous phase liquid contaminant the DNAPL vaporized within the heated soil region condenses and accumulates ahead of the steam condensation front. If enough DNAPL accumulates, gravitational forces can overcome trapping forces allowing the liquid contaminant to flow downward. By injecting air with steam, a portion of the DNAPL vapor remains suspended in equilibrium with the air, decreasing liquid contaminant accumulation ahead of the steam condensation front, and thus reducing the possibility of downward migration. In this work, a one-dimensional theoretical model is developed to predict the injection ratio of air to steam that will prevent the accumulation of volatile DNAPLs. The contaminated region is modeled as a one-dimensional homogeneous porous medium with an initially uniform distribution of a single component contaminant. Mass and energy balances are combined to determine the injection ratio of air to steam that eliminates accumulation of the contaminant ahead of the steam condensation front, and hence reduces the possibility of downward migration. The minimum injection ratio that eliminates accumulation is defined as the optimum injection ratio. Example calculations are presented for three DNAPLs, carbon tetrachloride (CCl 4), trichloroethylene (TCE), and perchloroethylene (PCE). The optimum injection ratio of air to steam is shown to depend on the initial saturation and the volatility of the liquid contaminant. Numerical simulation results are presented to validate the model, and to illustrate downward migration for ratios less than optimum. Optimum injection ratios determined from numerical simulations are shown to be in good agreement with the theoretical model.

Quantum interest in (3+1)-dimensional Minkowski space

International Nuclear Information System (INIS)

Abreu, Gabriel; Visser, Matt

2009-01-01

The so-called 'quantum inequalities', and the 'quantum interest conjecture', use quantum field theory to impose significant restrictions on the temporal distribution of the energy density measured by a timelike observer, potentially preventing the existence of exotic phenomena such as 'Alcubierre warp drives' or 'traversable wormholes'. Both the quantum inequalities and the quantum interest conjecture can be reduced to statements concerning the existence or nonexistence of bound states for a certain one-dimensional quantum mechanical pseudo-Hamiltonian. Using this approach, we shall provide a simple variational proof of one version of the quantum interest conjecture in (3+1)-dimensional Minkowski space.

Clean/alternative fueled fleet programs - 1990 Amendments to the Clean Air Act, the Colorado Air Pollution Prevention and Control Act, and Denver City and County regulations

International Nuclear Information System (INIS)

Bowles, S.L.; Manderino, L.A.

Despite substantial regulations for nearly two decades, attainment of this ambient standards for ozone and carbon monoxide (CO) remain difficult goals to achieve, Even with of ozone precursors and CO. The 1990 Amendments to the Clean Air Act (CAA90) prescribe further reductions of mobile source emissions. One such reduction strategy is using clean fuels, such as methanol, ethanol, or other alcohols (in blends of 85 percent or more alcohol with gasoline or other fuel), reformulated gasoline or diesel, natural gas, liquified petroleum gas, hydrogen, or electricity. There are regulatory measures involving special fuels which will be required in areas heavily polluted with ozone and CO. The state of Colorado recently passed the 1992 Air Pollution Prevention and Control Act which included provisions for the use of alternative fuels which will be implemented in 1994. In addition to adhering to the Colorado state regulations, the city and county of Denver also have regulations pertaining to the use of alternative fuels in fleets of 10 or more vehicles. Denver's program began in 1992. This paper will address the issue of fleet conversion and its impact on industry in Colorado, and Denver in particular

Telomerase activity and telomere length in the colorectal polyp-carcinoma sequence Actividad de la telomerasa y longitud del telómero en la secuencia pólipo-carcinoma colorrectal

Directory of Open Access Journals (Sweden)

2009-03-01

Full Text Available Objective: the role of telomerase activity and telomere length in the adenoma-carcinoma sequence of colon carcinogenesis has not been well established. The objective of this study was to determine telomerase activity and telomere length patterns in patients with adenomatous polyps either associated or not with colorectal cancer, as well as the role of telomeric instability in the adenoma-carcinoma sequence. Patients and methods: we included in the study 14 patients who underwent surgery for colorectal cancer and/or polyps. In 6 of these patients fresh samples of tumor tissue, polyps, and normal mucosa were obtained; in the 8 remaining cases, we collected only polyps and normal mucosa. We used the fluorescent-telomeric repeat amplification protocol assay (TRAP-F to determine telomerase activity and telomere length using Southern-blot testing. Results: telomerase activity was detected in 86% of polyps and 50% of associated normal mucosa. Mean telomerase activity in polyp tissue was 5.85; in the normal mucosa it was 0.58 TPG. Mean telomere length was 6.78 Kbp and 7.78, respectively. Polyps in patients without synchronous cancer had a telomerase activity that was significantly higher (9.4 than in those with cancer (1.1. Conclusions: telomerase activity increases in the colorectal adenoma-carcinoma sequence, concurrently with a decrease in telomere length. The presence of synchronous cancer modifies telomerase activity in polyps.Objetivo: el papel de la actividad de la telomerasa y la longitud del telómero en la secuencia adenoma-carcinoma de la carcinogénesis colónica no ha sido bien establecido.

Travel health prevention.

Korzeniewski, Krzysztof

All around the world there has been a rapid growth in the number of international travels. According to the World Tourism Organisation the number of international tourist arrivals reached 1,235 billion in 2016 and continues to grow at a high rate. This has been much due to the development of air transport (including low-cost airlines), increasingly common economic migration, a growing number of travellers visiting friends and relatives, and an increase in medical tourism. With tropical destinations becoming increasingly popular among travellers, doctors have seen a rising number of patients who seek medical advice on health risks prevalent in hot countries and health prevention measures to be taken in tropical destinations, especially where sanitation is poor. The risk for developing a medical condition while staying abroad depends on a variety of factors, including the traveller's general health condition, health prevention measures taken before or during travel (vaccinations, antimalarial chemoprophylaxis, health precautions during air, road and sea travel, proper acclimatisation, prevention of heat injuries, protection against local flora and fauna, personal hygiene, water, food and feeding hygiene), as well as the prevalence of health risk factors in a given location. Health prevention is a precondition for safe travel and maintaining good physical health; in the era of a rapid growth in international tourism it has become of key importance for all travellers.

In 1992, a clean air strategy will be developed to incorporate views of British Columbians on ways to meet goals related to air quality. A discussion paper is presented to provide information to those interested in participation in developing this strategy. The paper gives information on air quality issues important to the province, including local air quality, urban smog, ozone layer depletion, and global climate change. The views and concerns expressed by stakeholders who attended the Clean Air Conference in 1991 are summarized. The process used to develop the clean air strategy is outlined and some outcomes to be anticipated from the strategy are suggested, including policies and priorities for action to ensure clean air. Air pollutants of concern are total reduced sulfur, mainly from pulp mills and gas processing plants; smoke from wood burning; sulfur dioxide from pulp mills and gas plants; hydrogen fluoride from aluminum smelting; ground-level ozone in urban areas; and acid rain. Elements of a clean air strategy include a smoke management policy, management strategies for greenhouse gases and ozone smog, ozone layer protection measures, regional air quality management plans, and long-term planning efforts in energy use, transportation modes, community design, and land use. 12 refs., 14 figs., 2 tabs

2017-12-21

Adolescent males interested in sex with males (AMSM) are an important audience for HIV prevention interventions, but they are difficult to reach due to their age and social stigma. We aim to identify efficient methods to recruit and retain AMSM in online research. Interviews with 14-to-18-year-old AMSM (N=16) were conducted at 2017 Pride events in Boston, MA and Providence, RI. Participants reported that (1) social media platforms are viable recruitment venues; (2) recruitment advertisements should describe the study using colorful/bright pictures, familiar words, and information about compensation; (3) surveys should be recruitment and retention procedures to increase the efficiency of HIV prevention research for this at-risk group. ©Kimberly M Nelson, Jaime J Ramirez, Michael P Carey.

Condition monitoring a key component in the preventive maintenance

International Nuclear Information System (INIS)

Isar, C.

2006-01-01

The preventive maintenance programs are necessary to ensure that nuclear safety significant equipment will function when it is supposed to. Diesel generator, pumps, motor operated valves and air operated control valves are typically operated every three months. When you drive a car, you depend on lot of sounds, the feel of the steering wheel and gauges to determine if the car is running correctly. Similarly with operating equipment for a power plant - sounds or vibration of the equipment or the gauges and test equipment indicate a problem or degradation, actions are taken to correct the deficiency. Due to safety and economical reason diagnostic and monitoring systems are of growing interest in all complex industrial production. Diagnostic systems are requested to detect, diagnose and localize faulty operating conditions at an early stage in order to prevent severe failures and to enable predictive and condition oriented maintenance. In this context it is a need for using various on-line and off-line condition monitoring and diagnostics, non-destructive inspection techniques and surveillance. The condition monitoring technique used in nuclear power plant Cernavoda are presented in this paper. The selection of components and parameters to be monitored, monitoring and diagnostics techniques used are incorporated into a preventive maintenance program. Modern measurement technique in combination with advanced computerized data processing and acquisition show new ways in the field of machine surveillance. The diagnostic capabilities of predictive maintenance technologies have increased recently year with advances made in sensor technologies. The paper will focus on the following condition monitoring technique: - oil analysis - acoustic leakage monitoring - thermography - valve diagnostics: motor operated valve, air operated valve and check valve - motor current signature - vibration monitoring and rotating machine monitoring and diagnostics For each condition monitoring

People spend more than two thirds of their daily time indoors. Hence, maintaining a healthy indoor environment is indispensable for the prevention of building related illness. In Japan, guidelines for indoor air quality have been established for 13 volatile/semi-volatile organic compounds (VOCs/SVOCs). These guidelines are now under revision by the Committee on Sick House Syndrome: Indoor Air Pollution. In order to gain information on the current indoor air pollutants and their levels, we carried out a nation-wide survey of VOCs and aldehydes in indoor residential air during 2012-2013. In this review, I concisely summarized the current indoor air quality of Japan.

Few birth cohort studies have examined the role of traffic-related air pollution (TRAP) in the development of infantile atopic dermatitis (AD), but none have investigated the role of preventive factors such as green spaces. The aim of this study was to investigate whether exposure to nitrogen dioxide (NO₂) and particulate matter with an aerodynamic diameter of Health study. Subjects were geocoded to their residential addresses and matched with air pollution data modeled using land-use regression. Information on infantile AD was obtained by using a questionnaire administered to the parents or guardians of the children. The association between infantile AD and exposure to NO₂ and PM 10 was determined using logistic regression models. We assessed the effects of residential green spaces using stratified analyses and by entering product terms into the logistic regression models. The risk of infantile AD significantly increased with an increase in air pollution exposure during the first trimester of pregnancy. The adjusted odds ratio (OR) and 95% confidence interval (CI) were 1.219 (1.023-1.452) per 10 μg/m³ increase in PM 10 and 1.353 (1.027-1.782) per 10 ppb increase in NO₂. An increase in the green space within 200 m of residence was associated with a decreased risk of AD (OR = 0.996, 95% CI: 0.993-0.999). The stratified analysis of residential green space revealed stronger associations between infantile AD and PM 10 and NO₂ exposure during the first trimester in the areas in the lower tertiles of green space. This study indicated that exposure to TRAP during the first trimester of pregnancy is associated with infantile AD. Less residential green space may intensify the association between TRAP exposure and infantile AD.

2013-01-01

Technology enhanced learning (TEL) aims to design, develop and test sociotechnical innovations that will support and enhance learning practices of both individuals and organisations. It is therefore an application domain that generally covers technologies that support all forms of teaching and learning activities. Since information retrieval (in terms of searching for relevant learning resources to support teachers or learners) is a pivotal activity in TEL, the deployment of recommender systems has attracted increased interest. This brief attempts to provide an introduction to recommender systems for TEL settings, as well as to highlight their particularities compared to recommender systems for other application domains.

Landing Distance Minimization to Prevent Overrun Accidents Using Field Theory and Stabilizing Air Traffic - A Novel Approach

Science.gov (United States)

Krishna Kumar, R.; Navaneeth, M.; Shachin Shibi, R.

2017-09-01

Airplane is considered to be the pinnacle of engineering as it has proven that it is possible for a manmade object to fly. Before its invention, flying was just a dream for mankind. In such an esteemed domain, landing is the most challenging part and it is where a large number of accidents occur, especially due to overrun. As the name suggests, overrun accidents occur due to insufficient runway length. In the present study, the concept of planar electromagnetic fields is incorporated to minimize the landing distance of an aircraft, thus preventing the overrun accidents. As a result, unexpected losses can be avoided. In addition to this, the stability of air traffic control can be perpetuated and the fuel consumed during loitering time can be diminished.

2004-01-01

Therapeutic jurisprudence (TJ) and preventive law (PL) are used as two theoretical perspectives from which to examine the best interests of parties in mediation because of a dispute about a physician's practice. The focus is mediation provided by and/or for the medical regulator. The paper reviews the literature on TJ and PL, and their relationship to mediation, and demonstrates how medical regulators could benefit by working within a framework reflecting both these perspectives providing it does not involve an egregious matter. A TJ and PL framework would be of particular value in identifying cases for mediation and in evaluating resolutions to mediated disputes.

Effect of negative air ions on the potential for bacterial contamination of plastic medical equipment.

2010-04-12

In recent years there has been renewed interest in the use of air ionizers to control the spread of infection in hospitals and a number of researchers have investigated the biocidal action of ions in both air and nitrogen. By comparison, the physical action of air ions on bacterial dissemination and deposition has largely been ignored. However, there is clinical evidence that air ions might play an important role in preventing the transmission of Acinetobacter infection. Although the reasons for this are unclear, it is hypothesized that a physical effect may be responsible: the production of air ions may negatively charge items of plastic medical equipment so that they repel, rather than attract, airborne bacteria. By negatively charging both particles in the air and items of plastic equipment, the ionizers minimize electrostatic deposition on these items. In so doing they may help to interrupt the transmission of Acinetobacter infection in certain healthcare settings such as intensive care units. A study was undertaken in a mechanically ventilated room under ambient conditions to accurately measure changes in surface potential exhibited by items of plastic medical equipment in the presence of negative air ions. Plastic items were suspended on nylon threads, either in free space or in contact with a table surface, and exposed to negative ions produced by an air ionizer. The charge build-up on the specimens was measured using an electric field mill while the ion concentration in the room air was recorded using a portable ion counter. The results of the study demonstrated that common items of equipment such as ventilator tubes rapidly developed a large negative charge (i.e. generally >-100V) in the presence of a negative air ionizer. While most items of equipment tested behaved in a similar manner to this, one item, a box from a urological collection and monitoring system (the only item made from styrene acrylonitrile), did however develop a positive charge in the

Archaeogeophysical data acquisition and analysis at Tel Burna, Israel: a valuable opportunity for ongoing ground-truth investigation and collaboration (Invited)

Science.gov (United States)

Pincus, J. A.

2013-12-01

Tel Burna is a site in the Shephelah breadbasket region of the southern part of Israel. It dates to the Bronze and Iron Age periods, 13th - 7th c. BCE. It has been suggested by scholars to be the Biblical site of Libnah. Libnah is mentioned in the Old Testament as an Israelite desert camp that Joshua encamped and fought against (Joshua 10:29-31; Joshua 12:15). Later it was given as a city to the children of Aaron, it joined the Edomites in a revolt against the King of Judah, and finally during the reign of Hezekiah, Libnah was besieged by Sennacherib (2 Kings 19:8, Isaiah 37:8). Today the tel has a flat-topped shape, has an extensive size, and there are clear casemate wall fortifications dating to the 7th c. BCE surrounding it. Thus far silos, floors, a Late Bronze period cultic area, figurines, and other intriguing artifacts have been unearthed at the site. The site is ideal for a case-study in archaeological geophysics method and interpretation in the region because (1) we are involving the method early in what is expected to be a long timeline of ongoing excavations; (2) it appears we have only a few occupation layers with significant architecture built directly on the bedrock; and (3) there is a relatively unconvoluted geological and pedological context. After conversations with the Director of the Tel Burna Archaeological Project, Itzick Shai, it was decided that out of the three areas actively being excavated a ground penetrating radar (GPR) survey of Area B would be most optimal at this time. The goal was to locate the extent of the archaeological material on the leveled area, while also providing better insight to the cultic area presently being excavated. Area B has proven to have been occupied during the Late Bronze Age IIB (13th c. BCE), as evidenced by the large public building associated with cultic remains, and a complex of walls. Using a 400 MHz antenna, a 30x20 meter grid was surveyed in June 2013. The spacing between each profile was 0.30 meters

Polluted air--outdoors and indoors.

2005-09-01

Many air pollutants which are considered important in ambient (outdoor) air are also found, sometimes at higher levels, in indoor air. With demanding standards having been set for many of these pollutants, both in the workplace and ambient air, consideration of the problems posed by indoor pollution is gaining pace. Studies on exposure to pollutants found in the indoor domestic environment are increasing and are contributing to an already significant compilation of datasets. Improvement in monitoring techniques has helped this process. Documented reports of fatalities from carbon monoxide poisonings are still worrying. However, studies on health effects of non-fatal, long term, low dose, indoor exposure to carbon monoxide and other pollutants, are still inconclusive and too infrequently documented. Of particular concern are the levels of air pollutants found in the domestic indoor environment in developing countries, despite simple interventions such as vented stoves having shown their value. Exposure to biomass smoke is still a level that would be considered unacceptable on health grounds in developed countries. As in the occupational environment, steps need to be taken to control the risks from exposure to the harmful constituents of indoor air in the home. However, the difficulty regarding regulation of the domestic indoor environment is its inherent privacy. Monitoring levels of pollutants in the home and ensuring regulations are adhered to, would likely prove difficult, especially when individual behaviour patterns and activities have the greatest influence on pollutant levels in indoor air. To this end, the Department of Health is developing guidance on indoor air pollution to encourage the reduction of pollutant levels in indoor domestic air.

In recent years, a system has been proposed that utilizes river heat, air-heat, exhaust heat from a cooler, etc., in addition to natural energy for the heat pump. With the introduction of such system, the amount of energy used and that of CO2 exhaust will be greatly reduced, but annual expenses will be increased as it stands. In order to improve the cost efficiency of the system, a proposal has been made for the introduction of an economic policy such as the carbon tax and a low interest financing system. With these matters in the background, the subject study predicts the production of solar cells in the future and, on the basis of this production, determines the price, conversion efficiency and equipment energy of solar cells in the future. Using these values and taking into consideration the introduction of the carbon tax and the low interest financing system, the optimum area was determined for solar cells and heat concentrators in a future residential solar/air-heat energy system. The carbon tax, being imposed on all CO2 discharges, had a large effect. Moreover, as the tax increased, annual expenses decreased for the solar/air-heat system. 3 refs., 6 figs.

First and foremost, the danger of beryllium aerosols concerns a possibility of their inhalation. The situation is aggravated with high biological activity of the beryllium in a human lung. The small allowable beryllium aerosols` concentration in air poses a rather complex and expensive problem of the pollution prevention and clearing up of air. The delivery and transportation of beryllium aerosols from sites of their formation are defined by the circuit of ventilation, that forms aerodynamics of air flows in premises, and aerodynamic links between premises. The causes of aerosols release in air of premises from hoods, isolated and hermetically sealed vessels can be vibrations, as well as pulses of temperature and pressure. Furthermore, it is possible the redispersion of aerosols from dirty surfaces. The effective protection of air against beryllium aerosols at industrial plants is provided by a complex of hygienic measures: from individual means of breath protection up to collective means of the prevention of air pollution.

Lelieveld, Jos

2017-08-24

In atmospheric chemistry, interactions between air pollution, the biosphere and human health, often through reaction mixtures from both natural and anthropogenic sources, are of growing interest. Massive pollution emissions in the Anthropocene have transformed atmospheric composition to the extent that biogeochemical cycles, air quality and climate have changed globally and partly profoundly. It is estimated that mortality attributable to outdoor air pollution amounts to 4.33 million individuals per year, associated with 123 million years of life lost. Worldwide, air pollution is the major environmental risk factor to human health, and strict air quality standards have the potential to strongly reduce morbidity and mortality. Preserving clean air should be considered a human right, and is fundamental to many sustainable development goals of the United Nations, such as good health, climate action, sustainable cities, clean energy, and protecting life on land and in the water. It would be appropriate to adopt "clean air" as a sustainable development goal.

Air quality indices : a review

International Nuclear Information System (INIS)

Hewings, J.

2001-10-01

Pollution Probe presents some background information that will help in the development of a national Air Quality Index (AQI) in Canada. This report examines the issues that should be addressed in revising the national Index of the Quality of Air (IQUA) or creating a new national Air Quality Index. The IQUA was devised in 1976 and provides Canadians with real-time information on the state of community air quality by including major pollutants and their synergies. It is currently being used for air quality management plans and air quality alert systems. At the same time that the IQUA was devised, the United States Environmental Protection Agency (US EPA) produced a parallel air quality index known as the Pollution Standard Index (PSI) which incorporated 5 criteria pollutants (particulate matter, sulphur dioxide, carbon monoxide, nitrogen oxide and ground level ozone) for which national health-based standards were devised. In 1999, the US EPA renamed their index the Air Quality Index (AQI) and made revisions to the primary health-based national ambient air quality standards for ground-level ozone and particulate matter. Separate values for PM2.5 and PM10 were incorporated and mandatory reporting was required for metropolitan areas with populations of 350,000 or more. Similarly, the IQUA has undergone major developments that affect the validity of the index, including: rejection by the Working Group on Air Quality Objectives and Guidelines of the previous maximum desirable and maximum acceptable air quality criteria, recognition that standards for many of the contaminants are outdated, developing more sensitive instrumentation for real-time monitoring of contaminants. This report also describes the use of the national short term Air Quality Index by provincial, territorial and local authorities in Canada. Pollution Probe recommends setting up a mechanism to review and revise IQUA on a regular basis that would incorporate governments, the medical profession, special

In recent years air-sea interaction has emerged as a subject in its own right, encompassing small-scale and large-scale processes in both air and sea. Air-Sea Interaction: Laws and Mechanisms is a comprehensive account of how the atmosphere and the ocean interact to control the global climate, what physical laws govern this interaction, and its prominent mechanisms. The topics covered range from evaporation in the oceans, to hurricanes, and on to poleward heat transport by the oceans. By developing the subject from basic physical (thermodynamic) principles, the book is accessible to graduate students and research scientists in meteorology, oceanography, and environmental engineering. It will also be of interest to the broader physics community involved in the treatment of transfer laws, and thermodynamics of the atmosphere and ocean.

The prevention of congenital toxoplasmosis is based on providing information to women, serologic diagnosis and treatment of the infected mother and child. In this article we present the results of 12 years of implementation of a congenital toxoplasmosis prevention program in which we measured the mother's infection incidence rate, the transmission rate and the number and severity of infection in newborns. The study was performed on 12035 pregnant women in the period 2000-2011. The prevalence rate of antibodies against Toxoplasma gondii was 18.33% (2206/12035). Thirty-seven out of 9792 susceptible women presented acute infection and the mother's infection incidence rate was 3.78 per 1000 births. The transplacental transmission rate was 5.4% (2/37). Two newborns presented congenital toxoplasmosis infection, one had no clinical signs while the other presented strabismus and chorioretinitis. Thirty-five infected mothers and the two children with congenital infection were treated. The transmission rates obtained allow consider this prevention program as a valid resource to minimize the impact of congenital toxoplasmosis.

Fighting corrosion in air pollution control systems

International Nuclear Information System (INIS)

Rittenhouse, R.C.

1991-01-01

This paper reports that materials is the name of the game for corrosion prevention in air pollution control equipment. Whether the system is already in place, a retrofit, are specified for a new power pant, preventing corrosion is critical, because such deterioration easily undermines reliability. Hence, materials can heavily influence power plant compliance to the 1990 Clean Air Act amendments. Flue gas desulfurization (FGD) systems, perhaps the most vulnerable area to corrosion, are expected to be the method of choice for sulfur removal in many power plants in the near term. Components of these systems have various degrees of susceptibility to corrosion and related problems

Slx4 becomes phosphorylated after DNA damage in a Mec1/Tel1-dependent manner and is required for repair of DNA alkylation damage

Science.gov (United States)

Flott, Sonja; Rouse, John

2005-01-01

Members of the RecQ family of DNA helicases, mutated in several syndromes associated with cancer predisposition, are key regulators of genome stability. The Saccharomyces cerevisiae SLX4 gene is required for cell viability in the absence of Sgs1, the only yeast RecQ helicase. SLX4 encodes one subunit of the heterodimeric Slx1–Slx4 endonuclease, although its cellular function is not clear. Slx1–Slx4 was reported to preferentially cleave replication fork-like structures in vitro, and cells lacking SLX4 are hypersensitive to DNA alkylation damage. Here we report that Slx4 becomes phosphorylated in cells exposed to a wide range of genotoxins. Even though it has been proposed that the role of Slx4 is restricted to S-phase, Slx4 phosphorylation is observed in cells arrested in G1 or G2 phases of the cell cycle, but not during an unperturbed cell cycle. Slx4 phosphorylation is completely abolished in cells lacking the Mec1 and Tel1 protein kinases, critical regulators of genome stability, but is barely affected in the absence of both Rad53 and Chk1 kinases. Finally we show that, whereas both Slx1 and Slx4 are dispensable for activation of cell-cycle checkpoints, Slx4, but not Slx1, is required for repair of DNA alkylation damage in both aynchronously growing cells and in G2-phase-arrested cells. These results reveal Slx4 as a new target of the Mec1/Tel1 kinases, with a crucial role in DNA repair that is not restricted to the processing of stalled replisomes. PMID:15975089

This study evaluated the indoor air quality in Brazilian universities by comparing thirty air-conditioned (AC) (n = 15) and naturally ventilated (NV) (n = 15) classrooms. The parameters of interest were indoor carbon dioxide (CO2), temperature, relative humidity (RH), wind speed, viable mold, and airborne dust levels. The NV rooms had larger concentration of mold than the AC rooms (1001.30 ± 125.16 and 367.00 ± 88.13 cfu/m3, respectively). The average indoor airborne dust concentration exceeded the Brazilian standards (indoor air quality in Brazilian university classrooms affects the health of students. Therefore, indoor air pollution needs to be considered as an important public health problem.

Air pollution is a major concern of new civilized world, which has a serious toxicological impact on human health and the environment. It has a number of different emission sources, but motor vehicles and industrial processes contribute the major part of air pollution. According to the World Health Organization, six major air pollutants include particle pollution, ground-level ozone, carbon monoxide, sulfur oxides, nitrogen oxides, and lead. Long and short term exposure to air suspended toxicants has a different toxicological impact on human including respiratory and cardiovascular diseases, neuropsychiatric complications, the eyes irritation, skin diseases, and long-term chronic diseases such as cancer. Several reports have revealed the direct association between exposure to the poor air quality and increasing rate of morbidity and mortality mostly due to cardiovascular and respiratory diseases. Air pollution is considered as the major environmental risk factor in the incidence and progression of some diseases such as asthma, lung cancer, ventricular hypertrophy, Alzheimer's and Parkinson's diseases, psychological complications, autism, retinopathy, fetal growth, and low birth weight. In this review article, we aimed to discuss toxicology of major air pollutants, sources of emission, and their impact on human health. We have also proposed practical measures to reduce air pollution in Iran.

Highlights: ► Important factors that affect air-ingress process in the VHTRs were investigated and identified. ► Two air ingress mitigation concepts were developed using a root-cause analysis. ► These concepts were validated using computational fluid dynamic method. ► In-vessel helium injection and ex-vessel enclosure concept will mitigate air-ingress effectively. - Abstract: An air ingress accident following a postulated pipe break is considered a critical event for a very high temperature gas-cooled reactor (VHTR) safety. Following helium depressurization, it is anticipated that air will enter the core through the break leading to oxidation of the in-core graphite structures. Under extreme circumstances and without mitigation features this accident may lead to exothermic chemical reactions between graphite and oxygen depending on the accident scenario and the design. Under extreme circumstances (beyond design basis), a loss of structural integrity may occur in some core structures and lead to elevated release of radiological inventory for the fuel matrix. This paper discusses various air ingress mitigation concepts applicable for the VHTRs that would prevent core damage even in the most extreme scenarios. The study begins with identifying important factors (or phenomena) associated with the air ingress accident using root-cause analysis. By preventing main causes of the important events identified in the root-cause diagram, the basic air ingress mitigation ideas were conceived and developed. Among them, two concepts were finally evaluated as effective candidates. One concept is to inject helium directly into the lower plenum (direct in-vessel injection); the other concept is to enclose the reactor with a non-pressure boundary with an opening at the bottom (ex-vessel enclosure). Computational fluid dynamics (CFD) methods were used to evaluate these concepts for proof of these principles. Results indicate that both concepts can effectively suppress air

2017-11-01

Full Text Available The geothermal energy of groundwater has aroused increasing interest as a solution to climate change. The groundwater heat pumps (GWHP system using groundwater is the most environmentally friendly system to date and has been examined in several studies. However, biological clogging by microorganisms negatively affects the thermal efficiency of the GWHP system. In this study, we employed air surging, the most popular among well management methods, and pyrosequencing to analyze the genetic diversity in bacteria before and after air surging in a geothermal well. Furthermore, the diversity of dominant bacterial genera and those related to clogging were evaluated. The bacterial diversity of the groundwater well increased after air surging. Nevertheless, the proportion of bacterial genera thought to be related to microbiological clogging decreased. In cooling and heating systems based on the geothermal energy of groundwater, the wells should be maintained regularly by air surging to reduce efficiency problems caused by microbiological clogging and to prevent secondary damage to human health, e.g., pneumonia due to human pathogenic bacteria including Pseudomonas aeruginosa and Acinetobacter.

Since the epoch of the Chilean music historian Eugenio Pereira Salas this work has been considered as the first lyrical drama composed in the Chilean territory after the independence. The following essay discusses this point in depth on the basis of the libretto, which is the only element of this opera that has remained. The libretto reveals a concrete political project as well as a personal reflection on Ried's ideas along with his encounter with Chileans, Germans and indigenous people of the nineteenth century. In this regard, the figure of Aquinas Ried reaches a wider spectrum encompassing the musical and cosmopolitan life of the city of Valparaiso and the immigrants in 19th-century Chile.

The North American Free Trade Agreement/North American Agreement on Environmental Cooperation provides a mechanism for an international collaboration between the US, Canada, and Mexico to jointly develop, modify, or refine technologies that remediate or protect the environment. These countries have a vested interest in this type of collaboration because contaminants do not respect the boundaries of a manufacturing site, region, city, state, or country. The Environmental Sciences Division (ESD) at Oak Ridge National Laboratory (ORNL) consists of a diverse group of individuals who address a variety of environmental issues. ESD is involved in basic and applied research on the fate, transport, and remediation of contaminants; environmental assessment; environmental engineering; and demonstrations of advanced remediation technologies. The remediation and protection of the environment includes water, air, and soils for organic, inorganic, and radioactive contaminants. In addition to remediating contaminated sites, research also focuses on life-cycle analyses of industrial processes and the production of green technologies. The author focuses this discussion on subsurface remediation and pollution prevention; however, the research activities encompass water, soil and air and many of the technologies are applicable to all environments. The discussion focuses on the integration of biotechnology with remediation activities and subsequently linking these biological processes to other remediation technologies

After radiological emergencies, patients contaminated with radioactivity are taken to radiation emergency hospitals for treatment. Numerical simulations using the computer software 'Flow Designer R were made in order to evaluate indoor air contamination caused by the breathing out of contaminated air. The National Inst. of Radiological Sciences facility was used for the numerical evaluation. Results indicate that the dispersion of contaminated air depends on the characteristics of the contaminants, and that the dispersion range was limited and localised. Only medical staff standing in a special position near the patient was exposed to almost un-diluted contaminated air. Highly contaminated air was evacuated with a local exhaust pump system. Room air quality was monitored using a continuous air sampling system, but it was found that the sampling point was not representative for the purpose of radiation protection. From the air-flow analysis, some problems that affect radiological safety were revealed and valuable information and measures for preventing secondary contamination were determined. (authors)

These lines of evidence are: (a) that influenza is airborne; (b) that UV irradiation of the upper air of a room can provide safe and effective disinfection of air in the lower part of the room; and (c) that epidemic spread of airborne viral infections in humans can be prevented if the population under consideration remains in the UV-protected environment

Air toxics regulatory issues facing urban settings

1996-10-01

Biomarker research does not exist in isolation. Its usefulness can only be realized when it is translated into prevention strategies to protect public health. In the context of air toxics, these prevention strategies begin with the development of regulatory standards derived from risk assessment schemes. The Clean Air Act Amendments of 1990 list 189 air toxics, including many volatile organics, metals, and pesticides. The National Institute of Environmental Health Sciences (NIEHS), through its affiliation with the National Toxicology Program, has generated toxicity and carcinogenicity data on more than 100 of these air toxics. The NIEHS extramural and intramural research portfolios support a variety of projects that develop and validate biomarkers for use in environmental health science and risk assessment. Biomarkers have a tremendous potential in the areas of regulating air toxics and protecting public health. Risk assessors need data provided by biomarkers of exposure, biomarkers of close/pharmacokinetics, biomarkers of susceptibility or individual variability, and biomarkers of effects. The greatest benefit would be realized if biomarkers could be employed in four areas of primary and secondary prevention. The first is the use of biomarkers to enhance extrapolation of animal data to human exposure situations in establishing risk standards. The second is the use of biomarkers that assess noncancer, as well as cancer, end points. Important health end points include pulmonary dysfunction, immunotoxicity, and neurotoxicity. Third, biomarkers that serve as early warning signs to detect intermediate effects would enhance our ability to design timely and cost-effective intervention strategies. Finally, biomarkers used to evaluate the effectiveness of intervention strategies both in clinical and regulatory settings, would enable us to ensure that programs designed to protect public health do, in fact, achieve the desired outcome. 9 refs., 2 tabs.

Air quality management in Botswana

Directory of Open Access Journals (Sweden)

Modupe O. Akinola

2017-06-01

Full Text Available This paper examines air pollution situation and the history of air quality management in Botswana. The current air quality management in Botswana is still largely underpinned by the Atmospheric Pollution Prevention Act of 1971, supplemented by the more recently enacted legislations such as the Environmental Impact Assessment (EIA Act of 2010 and the Ambient Air Quality - Limits for Common Pollutants of 2012 published by the Botswana Bureau of Standards. Though commendable efforts have been made toward legislating against air and other forms of pollution, these have not yielded expected results in view of the prevailing levels of air pollutants like sulphur dioxide and fine particulate matters in the country’s atmospheric environment. Legislation as a sole measure may not be effective in tackling this challenge. Rather, government should also address some root-causes of the problem by making policies and programmes that will reduce unemployment and increase the earning capacity of citizenry. This will, among other things, effectively check poverty-induced biomass burning in the country. The paper looks at some other challenges of air pollution management and suggestions are made to tackle the identified problems.

Ca{sup 2+}/calmodulin-dependent protein kinase II (CaMKII) is activated by particulate matter (PM) isolated from ambient air and linked to prolonged repolarization and cardiac arrhythmia. We evaluated whether alpha B-crystallin (CryAB), a heat shock protein, could prevent the arrhythmogenic effects of PM by preventing CaMKII activation. CryAB was delivered into cardiac cells using a TAT-protein transduction domain (TAT-CryAB). ECGs were measured before and after tracheal exposure of diesel exhaust particles (DEP) and each intervention in adult Sprague–Dawley rats. After endotracheal exposure of DEP (200 μg/mL for 30 minutes, n = 11), QT intervals were prolonged from 115 ± 14 ms to 144 ± 20 ms (p = 0.03), and premature ventricular contractions were observed more frequently (0% vs. 44%) than control (n = 5) and TAT-Cry (n = 5). However, DEP-induced arrhythmia was not observed in TAT-CryAB (1 mg/kg) pretreated rats (n = 5). In optical mapping of Langendorff-perfused rat heats, compared with baseline, DEP infusion of 12.5 μg/mL (n = 12) increased apicobasal action potential duration (APD) differences from 2 ± 6 ms to 36 ± 15 ms (p < 0.001), APD restitution slope from 0.26 ± 0.07 to 1.19 ± 0.11 (p < 0.001) and ventricular tachycardia (VT) from 0% to 75% (p < 0.001). DEP infusion easily induced spatially discordant alternans. However, the effects of DEP were prevented by TAT-CryAB (1 mg/kg, n = 9). In rat myocytes, while DEP increased reactive oxygen species (ROS) generation and phosphated CaMKII, TAT-CryAB prevented these effects. In conclusion, CryAB, a small heat shock protein, might prevent the arrhythmogenic effects of PM by attenuating ROS generation and CaMKII activation. -- Highlights: ► Particulate matter (PM) increases arrhythmia. ► PM induced arrhythmias are related with oxidative stress and CaMKII activation. ► Alpha B-crystallin (CryAB) could attenuate the arrhythmogenic effect of PM. ► CryAB decreases oxidative stress and CaMKII activation

Heterogeneous Photocatalysis: Fundamentals and Application for Treatment of Polluted Air

Directory of Open Access Journals (Sweden)

Tomašić, V.

2011-07-01

Full Text Available The use of heterogeneous photocatalysts for the abatement of environmental problems has received increased attention during the last three decades. The photocatalyst used in most of these studies was titanium dioxide. This fact relates to the unique physical and chemical properties of titanium dioxide and similar semiconductor materials, such as ZnO, MgO,WO3, Fe2Oa, CdS, etc. that may be utilized for a wide range of potential applications. Specifically, upon ultraviolet irradiation these materials exhibit photocatalytic activity that enables the oxidative destruction of a wide range of organic compounds and biological species on their surface. In addition, these materials may also exhibit photocatalytically induced superhydrophilicity that converts the hydrophobic character of the surface to hydrophilic when exposed to UV light. This causes the formation of uniform water films on the surface of these materials, which prevents the adhesion of inorganic or organic components and thus retains a clean surface on the photocatalyst. Photocatalytic materials may be deployed on surfaces of various substrates, such as glass, ceramics or metals to provide layers that exhibit photocatalytic activity when they are exposed to light. Excitation of a photocatalyst leads to the creation of electrons and holes in the semiconductor material. Furthermore, these electrons and holes interact with molecules adsorbed on the semiconductor and can induce charge transfer process that results in the degradation of the adsorbate. The commercial potentials of heterogeneous photocatalysis are huge, including medical applications, application in the field of architecture (particularly for the cultural heritage purposes, facade paints, etc., automotive and food industries (cleaner technologies, non-fogging glass and mirrors, product safety, textile and glass industry, as well as in environmental protection (water and air purification and disinfection.

Physical cold atmospheric surface microdischarge (SMD) plasma operating in ambient air has promising properties for the sterilization of sensitive medical devices where conventional methods are not applicable. Furthermore, SMD plasma could revolutionize the field of disinfection at health care facilities. The antimicrobial effects on Gram-negative and Gram-positive bacteria of clinical relevance, as well as the fungus Candida albicans, were tested. Thirty seconds of plasma treatment led to a 4 to 6 log(10) CFU reduction on agar plates. C. albicans was the hardest to inactivate. The sterilizing effect on standard bioindicators (bacterial endospores) was evaluated on dry test specimens that were wrapped in Tyvek coupons. The experimental D(23)(°)(C) values for Bacillus subtilis, Bacillus pumilus, Bacillus atrophaeus, and Geobacillus stearothermophilus were determined as 0.3 min, 0.5 min, 0.6 min, and 0.9 min, respectively. These decimal reduction times (D values) are distinctly lower than D values obtained with other reference methods. Importantly, the high inactivation rate was independent of the material of the test specimen. Possible inactivation mechanisms for relevant microorganisms are briefly discussed, emphasizing the important role of neutral reactive plasma species and pointing to recent diagnostic methods that will contribute to a better understanding of the strong biocidal effect of SMD air plasma.

The use of support surfaces in the prevention and treatment of pressure ulcers prevention is an important part of care for a patient at risk and/or suffering from sore(s). Define which support surfaces to use in prevention and treatment of at-risk and/or pressure sore patients. A systematic review of the literature querying the several Pascal Biomed, PubMed and Cochrane Library databases from 2000 through 2010. RESULTS (GRADE A): In prevention, a structured foam mattress is more efficient than a standard hospital mattress. An alternating pressure mattress is more effective than a visco-elastic mattress limiting the occurrence heel pressure ulcers, but those that do occur are more serious. A low-air-loss bed is more efficient than a mixed pulsating air mattress in prevention of heel pressure ulcers. Some types of sheepskin can reduce sacral pressure ulcer incidence in orthopedic patients. Use of an overlay on an operating table limits the occurrence of peroperative and postoperative pressure ulcers. An air-fluidized bed improves pressure ulcer healing. The data in the literature are not always relevant and do not suffice to dictate a clinician's choices. We are compelled to recognize the methodological limitations of many studies, the lack of corporate interest in conducting such studies and the relatively small number of available trials. However, the effectiveness of some support surfaces reaches a sufficient level of evidence, especially when they are associated with postural, hydration and nutritional measures. Support surfaces are recommended in prevention and treatment of patients at risk and/or already suffering from pressure ulcer, and their use should constitute part of an overall preventive or curative strategy.

Prevention of DNA Rereplication Through a Meiotic Recombination Checkpoint Response

Directory of Open Access Journals (Sweden)

Nicole A. Najor

2016-12-01

Full Text Available In the budding yeast Saccharomyces cerevisiae, unnatural stabilization of the cyclin-dependent kinase inhibitor Sic1 during meiosis can trigger extra rounds of DNA replication. When programmed DNA double-strand breaks (DSBs are generated but not repaired due to absence of DMC1, a pathway involving the checkpoint gene RAD17 prevents this DNA rereplication. Further genetic analysis has now revealed that prevention of DNA rereplication also requires MEC1, which encodes a protein kinase that serves as a central checkpoint regulator in several pathways including the meiotic recombination checkpoint response. Downstream of MEC1, MEK1 is required through its function to inhibit repair between sister chromatids. By contrast, meiotic recombination checkpoint effectors that regulate gene expression and cyclin-dependent kinase activity are not necessary. Phosphorylation of histone H2A, which is catalyzed by Mec1 and the related Tel1 protein kinase in response to DSBs, and can help coordinate activation of the Rad53 checkpoint protein kinase in the mitotic cell cycle, is required for the full checkpoint response. Phosphorylation sites that are targeted by Rad53 in a mitotic S phase checkpoint response are also involved, based on the behavior of cells containing mutations in the DBF4 and SLD3 DNA replication genes. However, RAD53 does not appear to be required, nor does RAD9, which encodes a mediator of Rad53, consistent with their lack of function in the recombination checkpoint pathway that prevents meiotic progression. While this response is similar to a checkpoint mechanism that inhibits initiation of DNA replication in the mitotic cell cycle, the evidence points to a new variation on DNA replication control.

2017-12-01

We aimed to examine effectiveness of sodium hyaluronate-carboxymethly cellulose (NaH/CMC) for sealing pulmonary air leaks during postoperative period. The study was conducted in 16 male Sprague-Dawley rats. A linear insicion (length= 0.2 cm, depth= 0.1 cm) to the lung parenchyma on the inflated by a cutter was made. The animals were randomly divided; the control group (n= 8) and NaH/CMC-treated group (the study group, n= 8). Control group was left for physiologic healing while a NaH/CMC membrane was applied over the the incisional area in the study group. Then the pressure point where the air leakage observed was noted. No polymorphonucleer leucocytes (PMNL) infiltration was detected in control group, whereas PMNL infiltration was 0.38 ± 0.5 cell per 100 high field in study group (p= 0.234). The degree of macrophage, lymphocyte infiltration and the mean fibroblast count were found to be higher in study group compared with control group (p= 0.007, p= 0.02, p= 0.05, respectively). The mean pressure value for air leak to occur in the control group was 43.50 ± 9.55 mmHg whereas it was 73.75 ± 16.68 mmHg in the study group (p< 0.001). The data revealed that bioabsorbable NaH/CMC membrane accelerates healing with preserving the expansile character of lung parenchyma even in high ventilation pressures. However, further studies are required to assess the prevent impact of the pulmonary air-leak for NaH/CMC membrane.

Air leak after lung resection: pathophysiology and patients' implications.

Science.gov (United States)

Pompili, Cecilia; Miserocchi, Giuseppe

2016-02-01

Protocols for the management of air leaks are critical aspects in the postoperative course of patients following lung resections. Many investigations in the last decade are focusing on the chest tube modalities or preventative measures, however, little is known about the pathophysiology of air leak and the patient perception of this common complication. This review concentrates on understanding the reasons why a pulmonary parenchyma may start to leak or an air leak may be longer than others. Experimental works support the notion that lung overdistension may favor air leak. These studies may represent the basis of future investigations. Furthermore, the standardization of nomenclature in the field of pleural space management and the creation of novel air leak scoring systems have contributed to improve the knowledge among thoracic surgeons and facilitate the organization of trials on this matter. We tried to summarize available evidences about the patient perception of a prolonged air leak and about what would be useful for them in order to prevent worsening of their quality of life. Future investigations are warranted to better understand the pathophysiologic mechanisms responsible of prolonged air leak in order to define tailored treatments and protocols. Improving the care at home with web-based telemonitoring or real time connected chest drainage may in a future improve the quality of life of the patients experience this complication and also enhance hospital finances.

Towards Personal Exposures: How Technology Is Changing Air Pollution and Health Research.

Science.gov (United States)

Larkin, A; Hystad, P

2017-12-01

We present a review of emerging technologies and how these can transform personal air pollution exposure assessment and subsequent health research. Estimating personal air pollution exposures is currently split broadly into methods for modeling exposures for large populations versus measuring exposures for small populations. Air pollution sensors, smartphones, and air pollution models capitalizing on big/new data sources offer tremendous opportunity for unifying these approaches and improving long-term personal exposure prediction at scales needed for population-based research. A multi-disciplinary approach is needed to combine these technologies to not only estimate personal exposures for epidemiological research but also determine drivers of these exposures and new prevention opportunities. While available technologies can revolutionize air pollution exposure research, ethical, privacy, logistical, and data science challenges must be met before widespread implementations occur. Available technologies and related advances in data science can improve long-term personal air pollution exposure estimates at scales needed for population-based research. This will advance our ability to evaluate the impacts of air pollution on human health and develop effective prevention strategies.

Due to rapid urbanization, industrialization and motorization, a large number of Chinese cities are affected by heavy air pollution. In order to explore progress, remaining challenges, and sustainability of air pollution control in the Beijing-Tianjin-Hebei (BTH) region after 2013, a mixed method analysis was undertaken. The quantitative analysis comprised an overview of air quality management in the BTH region. Semi-structured expert interviews were conducted with 12 stakeholders from various levels of government and research institutions who played substantial roles either in decision-making or in research and advising on air pollution control in the BTH region. The results indicated that with the stringent air pollution control policies, the air quality in BTH meets the targets of the Air Pollution Prevention and Control Action Plan. However, improvements vary across the region and for different pollutants. Although implementation has been decisive and was at least in parts effectively enforced, significant challenges remained with regard to industrial and traffic emission control, and national air quality limits continued to be significantly exceeded and competing development interests remained mainly unsolved. There were also concerns about the sustainability of the current air pollution control measures especially for industries due to the top-down enforcement, and the associated large burden of social cost including unemployment and social inequity resulting industrial restructuring. Better mechanisms for ensuring cross-sectoral coordination and for improved central-local government communication were suggested. Further suggestions were provided to improve the conceptual design and effective implementation of respective air pollution control strategies in BTH. Our study highlights some of the major hurdles that need to be addressed to succeed with a comprehensive air pollution control management for the Chinese mega-urban agglomerations. PMID:29425189

An air riding seal for a turbine in a gas turbine engine, where an annular piston is axial moveable within an annular piston chamber formed in a stator of the turbine and forms a seal with a surface on the rotor using pressurized air that forms a cushion in a pocket of the annular piston. A purge cavity is formed on the annular piston and is connected to a purge hole that extends through the annular piston to a lower pressure region around the annular piston or through the rotor to an opposite side. The annular piston is sealed also with inner and outer seals that can be a labyrinth seal to form an additional seal than the cushion of air in the pocket to prevent the face of the air riding seal from overheating.

Fermilab has developed a second electron lens (TEL-2) for beam-beam compensation in the Tevatron as part of its Run II upgrade program. Operation of the beam position monitors (BPMs) in the first electron lens (TEL-1) showed a systematic transverse position difference between short proton bunches (2 ns sigma) and long electron pulses (˜1 us) of up to ˜1.5 mm. This difference was attributed to frequency dependence in the BPM system. The TEL-2 BPMs utilize a new, compact four-plate design with grounding strips between plates to minimize crosstalk. In-situ measurements of these new BPMs are made using a stretched wire pulsed with both proton and electron beam formats. In addition, longitudinal impedance measurements of the TEL-2 are presented. Signal processing algorithm studies indicate that the frequency-dependent transverse position offset may be reduced to ˜0.1 mm for the beam structures of interest.

Full Text Available Background Some environmental factors such as the ambient temperature, radiant temperature, humidity and air velocity as well as clothing and activity level are effective to induce heat strain on the workers. Objectives The current study aimed to evaluate the effect of air velocity on Iranian veiled females at various exercise intensities and climatic conditions. Methods The current experimental study was conducted on 51 healthy veiled females with Islamic clothing (n = 30 in two hot-dry climatic chambers (wet-bulb globe temperature (WBGT = 32 ± 0.1°C and WBGT = 30 ± 0.1°C, 40% relative humidity (RH without air velocity and (n = 21 with air velocity 0.31 m/s in sitting and light workload conditions, respectively, for 60 minutes. The WBGT, oral temperature and heart rate were measured simultaneously every five minutes during the heat exposure and resting state. Data were analyzed using correlation and line regression by SPSS ver. 16. Results In both groups, oral temperature and heart rate increased during heat exposure. The increase of oral temperature and heart rate were larger in the group with air velocity (sitting position, 37.05 ± 0.20°C, 98.30 ± 7.79 bpm, light workload, 37.34 ± 0.24°C, 124.08 ± 6.09 bpm compared those of the group without air velocity (sitting position, 36.70 ± 0.36°C, 69.74 ± 0.98 bpm, light workload, 36.71 ± 0.27°C, 110.78 ± 17.9 bpm. The difference in physiological strain index (PSI between resting and low workload were higher in with air velocity group than those of the group without air velocity. Conclusions The results showed that the heat stress increased by increasing air velocity and humidity in both groups. The air velocity with high humidity can be considered as a positive factor in the occurrence of heat strain. Therefore, the incidence of heat stress decreases with the increase of humidity and reduction of air velocity or with increase of air velocity and reduction of humidity in Iranian veiled

Given here is a definition of Liquid Air Cycle Engines (LACE) and existing relevant technologies. Heat exchanger design and fabrication techniques, the handling of liquid hydrogen to achieve the greatest heat sink capabilities, and air decontamination to prevent heat exchanger fouling are discussed. It was concluded that technology needs to be extended in the areas of design and fabrication of heat exchangers to improve reliability along with weight and volume reductions. Catalysts need to be improved so that conversion can be achieved with lower quantities and lower volumes. Packaging studies need to be investigated both analytically and experimentally. Recycling with slush hydrogen needs further evaluation with experimental testing.

Impacts of Changes of Indoor Air Pressure and Air Exchange Rate in Vapor Intrusion Scenarios.

Shen, Rui; Suuberg, Eric M

2016-02-01

There has, in recent years, been increasing interest in understanding the transport processes of relevance in vapor intrusion of volatile organic compounds (VOCs) into buildings on contaminated sites. These studies have included fate and transport modeling. Most such models have simplified the prediction of indoor air contaminant vapor concentrations by employing a steady state assumption, which often results in difficulties in reconciling these results with field measurements. This paper focuses on two major factors that may be subject to significant transients in vapor intrusion situations, including the indoor air pressure and the air exchange rate in the subject building. A three-dimensional finite element model was employed with consideration of daily and seasonal variations in these factors. From the results, the variations of indoor air pressure and air exchange rate are seen to contribute to significant variations in indoor air contaminant vapor concentrations. Depending upon the assumptions regarding the variations in these parameters, the results are only sometimes consistent with the reports of several orders of magnitude in indoor air concentration variations from field studies. The results point to the need to examine more carefully the interplay of these factors in order to quantitatively understand the variations in potential indoor air exposures.

Professional medical organizations and commercial conflicts of interest: ethical issues.

Science.gov (United States)

Brody, Howard

2010-01-01

The American Academy of Family Physicians (AAFP) has recently been criticized for accepting a large corporate donation from Coca-Cola to fund patient education on obesity prevention. Conflicts of interest, whether individual or organizational, occur when one enters into arrangements that reasonably tempt one to put aside one's primary obligations in favor of secondary interests, such as financial self-interest. Accepting funds from commercial sources that seek to influence physician organizational behavior in a direction that could run counter to the public health represents one of those circumstances and so constitutes a conflict of interest. Most of the defenses offered by AAFP are rationalizations rather than ethical counterarguments. Medical organizations, as the public face of medicine and as formulator of codes of ethics for their physician members, have special obligations to adhere to high ethical standards.

Medical merchants: conflict of interest, office product sales and notifiable conduct.

Parker, Malcolm H; Wardle, Jon L; Weir, Michael; Stewart, Cameron L

2011-01-03

Professional ethical codes identify the issue of conflict of interest, which can distort doctors' objective judgements concerning the best interests of patients. Legal fiduciary duties may be owed by doctors to patients in situations of potential conflict of interest. Prescribing and dispensing functions have been largely legally separated to prevent conflicts of interest arising. The advent of integrative medicine has been accompanied by an apparent growth of in-house selling of therapeutic products. Medical merchandising constitutes a prima-facie conflict of interest and may amount to notifiable conduct under the Health Practitioner Regulation National Law provisions. We believe that doctors who sell therapeutic products should adhere to strict conditions to avoid significantly departing from accepted professional standards. Doctors who have a reasonable belief that a colleague is failing to comply with these conditions could consider notifying the Medical Board of Australia.

There is growing interest in the association between ambient air pollution and congestive heart failure (CHF), but research data from developing countries are very limited. The primary aim of this study was to examine the association between short-term exposure to air pollution and hospital admission for CHF in China. A time-stratified case-crossover study was conducted between 2014 and 2015 in 26 large Chinese cities among 105,501 CHF hospitalizations. Conditional logistic regression models were applied to estimate the percentage changes in CHF admissions in relation to per interquartile range increases in air pollutant concentrations. Air pollution was positively associated with CHF hospitalizations. An interquartile range increase in fine particulate, particulate matter less than 10 µm in aerodynamic diameter, sulfur dioxide, nitrogen dioxide, carbon monoxide, and ozone concentrations on the current day corresponded to 1.2% (95% confidence interval [CI] 0.5%, 1.8%), 1.3% (95% CI 0.5%, 2.0%), 1.0% (95% CI 0.2%, 1.7%), 1.6% (95% CI 0.6%, 2.5%), 1.2% (95% CI 0.5%, 1.9%), and 0.4% (95% CI -0.9%, 1.7%) increases in CHF admissions, respectively. In conclusion, our findings contribute to the limited scientific literature concerning the effects of air pollution on CHF risk for high-exposure settings typical in developing countries, which may have significant public health implications for prevention of CHF in China.

Full Text Available In the 1960s,the French artistic and intellectual avant garde showed a renewed interest for Stéphane Mallarmé, as illustrated by the debates published in the magazine Tel Quel, especially between 1967 and 1969. This article makes an overview of these controversies: Why this renewed interest in Mallarmé? How did the new reading of his work depart from Sartre's? What were the, often irreconcilable, positions of the magazine’s contributors with regard to his figure? This account will ultimately be aimed at understanding the «Mallarmé question», as it was defined by Tel Quel’s founding member Philippe Sollers, in its specific historical context.

Full Text Available Numerous environmental justice studies have confirmed a relationship between population characteristics such as low-income or minority status and the location of environmental health hazards. However, studies of the health risks from exposure to harmful substances often do not consider their toxicological characteristics. We used two different methods, the unit-hazard and the distance-based approach, to evaluate demographic and socio-economic characteristics of the population residing near industrial facilities in the City of Toronto, Canada. In addition to the mass of air emissions obtained from the national pollutant release inventory (NPRI, we also considered their toxicity using toxic equivalency potential (TEP scores. Results from the unit-hazard approach indicate no significant difference in the proportion of low-income individuals living in host versus non-host census tracts (t(107 = 0.3, P = 0.735. However, using the distance-based approach, the proportion of low-income individuals was significantly higher (+5.1%, t(522 = 6.0, P <0.001 in host tracts, while the indicator for “racialized” communities (“visible minority” was 16.1% greater (t(521 = 7.2, P <0.001 within 2 km of a NPRI facility. When the most toxic facilities by non-carcinogenic TEP score were selected, the rate of visible minorities living near the most toxic NPRI facilities was significantly higher (+12.9%, t(352 = 3.5, P = 0.001 than near all other NPRI facilities. TEP scores were also used to identify areas in Toronto that face a double burden of poverty and air toxics exposure in order to prioritise pollution prevention.

Regarding global warming issue, one of the impact that is very interesting to be investigated is sea level rise. Sea level rise is predicted has very big impact since, in general, in coastal areas locate a lot of important activities for such city or country. On the context of Indonesian locality, most of big cities such as Jakarta, Surabaya, Semarang, Makasar, etc. are located on the coastal area. Since a lot of important activities located on those cities, in general, sea level rise will influence the development processes of those cities. On the basis of the observation gathering in Surabaya City, the impact of sea level rise will influence not only the development of coastal area but also development of Surabaya City in general. The influence is because the area accommodates activities which are very important in city development both for present and future. The activities are port, industrial estate and location for new housing.

Guidelines for prevention in psychology.

Science.gov (United States)

2014-04-01

The effectiveness of prevention to enhance human functioning and reduce psychological distress has been demonstrated. From infancy through adulthood, access to preventive services and interventions is important to improve the quality of life and human functioning and reduce illness and premature death. The importance of prevention is consistent with the Patient Protection and Affordable Care Act of 2010. Even with the increased focus on prevention, psychology training programs rarely require specific courses on prevention. In particular, conceptualizations about best practices in prevention, particularly at the environmental level, are lacking. Therefore, psychologists engaged in prevention can benefit from a set of guidelines that address and inform prevention practices. Accordingly, the Guidelines for Prevention in Psychology are intended to "inform psychologists, the public, and other interested parties regarding desirable professional practices" in prevention. The Prevention Guidelines are recommended based on their potential benefits to the public and the professional practice of psychology. They support prevention as an important area of practice, research, and training for psychologists. The Guidelines give increased attention to prevention within APA, encouraging psychologists to become involved with preventive activities relevant to their area of practice.

Pneumonia is the 2nd leading cause of years of life lost worldwide and is a common cause of adult admissions to hospital in sub-Saharan Africa. Risk factors for adult pneumonia are well characterised in developed countries, but are less well described in sub-Saharan Africa where HIV is a major contributing factor. Exposure to indoor and outdoor air pollution is high, and tobacco smoking prevalence is increasing in sub-Saharan Africa, yet the contribution of these factors to the burden of chronic respiratory diseases in sub-Saharan Africa remains poorly understood. Furthermore, the extent to which the presence of chronic respiratory diseases and exposure to air pollution contribute to the burden of pneumonia is not known. The Acute Infection of the Respiratory Tract Study (The AIR Study) is a case-control study to identify preventable risk factors for adult pneumonia in the city of Blantyre, Malawi. Cases will be adults admitted with pneumonia, recruited from Queen Elizabeth Central Hospital, the largest teaching hospital in Malawi. Controls will be adults without pneumonia, recruited from the community. The AIR Study will recruit subjects and analyse data within strata defined by positive and negative HIV infection status. All participants will undergo thorough assessment for a range of potential preventable risk factors, with an emphasis on exposure to air pollution and the presence of chronic respiratory diseases. This will include collection of questionnaire data, clinical samples (blood, urine, sputum and breath samples), lung function data and air pollution monitoring in their home. Multivariate analysis will be used to identify the important risk factors contributing to the pneumonia burden in this setting. Identification of preventable risk factors will justify research into the effectiveness of targeted interventions to address this burden in the future. The AIR Study is the first study of radiologically confirmed pneumonia in which air pollution exposure

Effect of Air-Curtain Discharge Speed on the Effectiveness of Vortex-like Air-Curtain Approach for Severe Accident Management

International Nuclear Information System (INIS)

Ullah, Sana; Yim, Man Sung

2017-01-01

The purpose of air-curtain installation is to isolate reactor containment from outside environment, confine the leaking radioactive material in a localized area, and minimize the impact of outside wind. The wind could blow away airborne radioactive material immediately after discharge leaving little room for effective capturing. Therefore, vortex-like air-curtain plays an important role in this process, and its effectiveness could severely influence the performance of overall system. An approach based on vortex-like air-curtain was proposed earlier for preventing spread of radioactive material to the environment and mitigate subsequent radiological consequences. Effect of air-curtain discharge speed, and discharge angle was studied, and a quantitative account of air curtain in terms of effectiveness parameter was performed in this work. It was found that for given wind speed, air-curtain effectiveness would improve with increase in air-curtain discharge speed to an extent, after which any increase in discharge velicity could deteriorate the performance, due to imbalance between discharge and wind speed. Keeping air-curtain discharge at an angle of 15° opposite to the predominant flow direction is devised.

Sixteen pumice samples produced by the youngest eruption sequences of Mt. Pelato (Island of Lipari, Italy) were analyzed with instrumental neutron activation analysis (INAA) for their major and trace element contents, in particular Al, Ba, Ca, Ce, Co, Cr, Cs, Dy, Eu, Fe, Hf, K, La, Lu, Mn, Na, Nd, Rb, Sb, Sm, Ta, Tb, Th, Ti, U, V, Yb, Zn, and Zr. A pumice from the archaeological excavation in Tel Megadim, Israel, could be correlated to this volcanic source, using its chemical fingerprint. This result, together with the background information about the well dated eruption cycles of this volcano, lead to the assumption that trade connections existed between cultures in Palestine and the Tyrrhenian region during the Persian Period (approx. between the 6th and 3rd century B.C.), in spite of the long distance of over 2000 km.

2014-12-01

Full Text Available Abstract This study investigates the influence of content-related conditions on adult second language learners’ task motivation during interactive tasks. It also aims to identify what is referred to as interestingness conditions within task content, that is, elements that are intrinsically interesting to most individuals. The investigation was conducted with 38 adult Korean English learners of intermediate proficiency in a conversation course as part of a TESOL certificate program. Using a mixed methods approach to research, results from a task motivation questionnaire, a topic preference questionnaire, and interviews show that content associated with immediate personal life themes such as personal growth, human relationships, and life challenges is perceived to be more intrinsically interesting than that associated with more remote and abstract topics such as those related to global issues and current affairs. Consequently, incorporating life themes into adult-based courses, especially through story-based texts, may act as an important springboard for active motivational engagement during task-based interaction. Résumé Cette étude examine l’influence des conditions, en fonction du contenu, de certaines tâches interactives sur la motivation d’adultes apprenant une langue seconde.

Diagnosis of abnormal patterns in multivariate microclimate monitoring: a case study of an open-air archaeological site in Pompeii (Italy).

Science.gov (United States)

Merello, Paloma; García-Diego, Fernando-Juan; Zarzo, Manuel

2014-08-01

Chemometrics has been applied successfully since the 1990s for the multivariate statistical control of industrial processes. A new area of interest for these tools is the microclimatic monitoring of cultural heritage. Sensors record climatic parameters over time and statistical data analysis is performed to obtain valuable information for preventive conservation. A case study of an open-air archaeological site is presented here. A set of 26 temperature and relative humidity data-loggers was installed in four rooms of Ariadne's house (Pompeii). If climatic values are recorded versus time at different positions, the resulting data structure is equivalent to records of physical parameters registered at several points of a continuous chemical process. However, there is an important difference in this case: continuous processes are controlled to reach a steady state, whilst open-air sites undergo tremendous fluctuations. Although data from continuous processes are usually column-centred prior to applying principal components analysis, it turned out that another pre-treatment (row-centred data) was more convenient for the interpretation of components and to identify abnormal patterns. The detection of typical trajectories was more straightforward by dividing the whole monitored period into several sub-periods, because the marked climatic fluctuations throughout the year affect the correlation structures. The proposed statistical methodology is of interest for the microclimatic monitoring of cultural heritage, particularly in the case of open-air or semi-confined archaeological sites.

Contingency power for small turboshaft engines using water injection into turbine cooling air

Science.gov (United States)

Biesiadny, Thomas J.; Berger, Brett; Klann, Gary A.; Clark, David A.

1987-01-01

Because of one engine inoperative requirements, together with hot-gas reingestion and hot day, high altitude takeoff situations, power augmentation for multiengine rotorcraft has always been of critical interest. However, power augmentation using overtemperature at the turbine inlet will shorten turbine life unless a method of limiting thermal and mechanical stresses is found. A possible solution involves allowing the turbine inlet temperature to rise to augment power while injecting water into the turbine cooling air to limit hot-section metal temperatures. An experimental water injection device was installed in an engine and successfully tested. Although concern for unprotected subcomponents in the engine hot section prevented demonstration of the technique's maximum potential, it was still possible to demonstrate increases in power while maintaining nearly constant turbine rotor blade temperature.

Research links air pollution mostly to respiratory and cardiovascular disease. The effects of air pollution on the central nervous system (CNS) are not broadly recognized. Urban outdoor pollution is a global public health problem particularly severe in megacities and in underdeveloped countries, but large and small cities in the United States and the United Kingom are not spared. Fine and ultrafine particulate matter (UFPM) defined by aerodynamic diameter (<2.5-μm fine particles, PM2.5, and <100-nm UFPM) pose a special interest for the brain effects given the capability of very small particles to reach the brain. In adults, ambient pollution is associated to stroke and depression, whereas the emerging picture in children show significant systemic inflammation, immunodysregulation at systemic, intratechal and brain levels, neuroinflammation and brain oxidative stress, along with the main hallmarks of Alzheimer and Parkinson's diseases: hyperphosphorilated tau, amyloid plaques and misfolded α-synuclein. Animal models exposed to particulate matter components show markers of both neuroinflammation and neurodegeneration. Epidemiological, cognitive, behavioral and mechanistic studies into the association between air pollution exposures and the development of CNS damage particularly in children are of pressing importance for public health and quality of life. Primary health providers have to include a complete prenatal and postnatal environmental and occupational history to indoor and outdoor toxic hazards and measures should be taken to prevent or reduce further exposures.

The objective of the study was to assess the actual ventilation and indoor air quality in the Finnish building stock (dwellings and day-care centers) with special reference to the existing guideline values. Furthermore, the objective was to evaluate the occurrence of symptoms and perceptions among occupants (adult residents, children, workers) in relation to ventilation system, ventilation rate and dampness. The measurements of ventilation and indoor air quality in the dwellings and day-care centers included ventilation rate, CO{sub 2} concentration, and temperature and humidity. Self- and parent-administered questionnaires were distributed to the occupants inquiring their personal characteristics, occurrence of symptoms of interest, perceived indoor air quality and details of their home and work environments. Airflows and air change rates varied remarkably both in the dwellings and day-care centers. In the majority of the dwellings and day-care centers, the Finnish guideline values of ventilation rates were not achieved. No consistent associations were observed between the magnitude of mechanical ventilation rates and the occurrence of eye, respiratory, skin and general symptoms, that is, symptoms of sick building syndrome (SBS) among the day-care workers. The results indicate that there is much room for improvement in the ventilation and indoor air quality of Finnish dwellings and day-care centers. The control of ventilation, temperature and humidity and the prevention of water damage are important issues on which to concentrate in the future. There is need to improve the quality in all phases of construction: design, installation, adjustment, operation, and maintenance

Full Text Available Galls surveys in Paraná are scarce and most sampling efforts in Brazil have still been concentrated on Cerrado regions. In this context, the present study investigated an area of semideciduous forest of Fazenda Monte Alegre in Telêmaco Borba, in order to contribute to the knowledge of galls in the state. Samples were collected on a 300m long track and 5m width, through active search up to two meters high. Fourty-one morphotypes were found, thirteen of which were identified to the host plant species level, ten according to level of genus, ten to family level and eight morphotypes were not identified. Among the identified families, Solanaceae, Asteraceae, Euphorbiaceae, Bignoniaceae, Melastomataceae and Leguminosae-Fabaceae represented the greatest quantity of morphotypes. Most of them occurred on the leaf (39%, 98.6% are entomogenous. 70.7% are glabrous, and as for the shape, most of them were classified as globular (43.9%. As for the way galls grouping on host plants, 46.3% showed up in isolation, and 53.7% in groupings. This study has contributed to enrich the knowledge on galls in the state of Paraná and for the Atlantic Forest Biome.

Full Text Available In the quest for energy conservative building design, there is now a great opportunity for a flexible and sophisticated air conditioning system capable of addressing better thermal comfort, indoor air quality, and energy efficiency, that are strongly desired. The variable refrigerant volume air conditioning system provides considerable energy savings, cost effectiveness and reduced space requirements. Applications of intelligent control like fuzzy logic controller, especially adapted to variable air volume air conditioning systems, have drawn more interest in recent years than classical control systems. An experimental analysis was performed to investigate the inherent operational characteristics of the combined variable refrigerant volume and variable air volume air conditioning systems under fixed ventilation, demand controlled ventilation, and combined demand controlled ventilation and economizer cycle techniques for two seasonal conditions. The test results of the variable refrigerant volume and variable air volume air conditioning system for each techniques are presented. The test results infer that the system controlled by fuzzy logic methodology and operated under the CO2 based mechanical ventilation scheme, effectively yields 37% and 56% per day of average energy-saving in summer and winter conditions, respectively. Based on the experimental results, the fuzzy based combined system can be considered to be an alternative energy efficient air conditioning scheme, having significant energy-saving potential compared to the conventional constant air volume air conditioning system.

Described by Durkheim (1966) as the crudest expression of the social phenomena, suicide is of interest to clinicians, academics and researchers. Within the academic context, this issue has to be addressed and prevented. We are interested in sharing the process of participative action that led to the creation of a Suicide Prevention Program (SPP) for college students. Based on knowledge that was generated through a collaborative effort among all sectors of the academic community, we developed a prevention campaign that is culturally sensitive to our university's environment. This campaign is directed towards overcoming the stigma of seeking help and is characterized by promoting a sense of wellbeing in a holistic manner, paying attention not only to the individual, but also to elements of their sociocultural environment.

Biomass energy, air pollution and health

International Nuclear Information System (INIS)

Mathis, Paul

2014-06-01

This article reports the negative effects on human health due to the use of biomass for energy. In addition to the emission of nitrogen oxides and of metals, these effects result largely from an incomplete combustion, generating various air pollutants: fine particles, carbon monoxide, volatile organic compounds and aromatic polycyclic hydrocarbons. Four situations are discussed: indoor air pollution due to cooking in developing countries, residential wood combustion for heating, the use of biofuels, and waste incineration. In all cases, negative health effects have been demonstrated, but they can be prevented by appropriate strategies. (author)

Recent studies have shown that women are more likely than men to use the Internet to seek health information and that the use of technology is common among perinatal women. Access to the Internet is growing through the global use of mobile phones and apps, in both developed and less developed countries. This pattern is particularly relevant for clinicians and researchers who are interested in the use of technologies to disseminate perinatal depression interventions. In a cross-sectional anonymous online survey for English and Spanish-speaking perinatal women, 509 pregnant (77.6 percent) and postpartum (22.4 percent) women provided demographic and Information and Communication Technologies data. Results indicated that the single device with greatest access was the mobile phone (47.5 percent). The majority of the sample had Internet access through mobile phones, computers, or both. Significant differences in socioeconomic status were found for Internet seeking behavior of health-related information and downloading apps between those with and without Internet access. Ninety percent of respondents (n = 267) searched for health-related information and 72.3 percent had downloaded any kind of app. More than half of respondents (57 percent, n = 188) downloaded a health-related app and 26.9 percent reported having paid for the apps. This study shows preliminary evidence to suggest the need to design, develop, and test apps that aim to disseminate prevention programs for perinatal depression.

Full Text Available The increasing interest in air conditioning systems for residential applications in Poland will certainly increase the demand for electricity during the summer period. Due to this fact a growing interest in solutions that help to lower the electricity consumption in this sector is observed. The problem of increased energy demand for air conditioning purposes can be solved by transfer the consumption of electricity from the grid system to renewable energy sources (RES. The greatest demand for cooling occurs during the biggest sunlight. This is the basis for the analysis of technical power system based on photovoltaic cells (PV to power the split type air conditioner. The object of the study was the commercial residential airconditioning inverter units with a capacity of 2.5kW. A network electricity production system for their own use with the possibility of buffering energy in batteries (OFF-GRID system. Currently, on the Polish market, there are no developed complete solutions dedicated to air conditioning systems based on PV. In Poland, solar energy is mainly used for heat production in solar collectors. The proposed solution will help to increase the popularity of PV systems in the Polish market as an alternative to other RES. The basic conclusion is that the amount of PV energy generated was sufficient to cover the daily energy requirement of the air conditioner.
