The food production and consumption balance in sub-Saharan Africa under different SSPs, from 2010 to 2050

NASA Astrophysics Data System (ADS)

Wada, Y.; Luan, Y.; Fischer, G.; Sun, L.; Shi, P.

2015-12-01

Forcing with the population growth and consequently increasing food requirement, food security in sub-Saharan Africa is one of the most emergent and challenging issues. The purposes of this work are 1) what's the future food requirement and their food security status in each sub-Saharan African countries? What is the distance from current and future food security status, corresponding to the food requirement, to the targeted food security status? 2) To what extent Sub-Saharan countries could meet their present and future food requirement, and whether they have potential to improve their food insecurity status on currently cultivated land? 3) Whether or, if there have, how the pressures on land resources from meeting the food requirements? To figure those questions out, we firstly use socio-economic pathways datasets, and historical food diet pattern classification to forecast the 2010-2050 food commodity and feed calories demand per country. A new food security indicator, which considered the influences of both the food energy and quality intake, was used to evaluate the food insecurity status and the distances to different targeted statuses of the specific country. The latest Global Agro-Ecological Zones (GAEZ) databases were used to estimate the current and future crop yield gap and crop potential production. For current to future scenario analysis, we considered population growth, dietary change, climate change, agricultural input level, and target food security status. Then the balance of food requirement with the current and potential crop production was analyzed for different scenarios. Land requirements were calculated for meeting those food requirements, and the pressures on land resources are evaluated. Our works are hoping to provide scientific-based evidences for policy recommendations for local government to tackle food insecurity problems in Sub-Saharan Africa.

[Global environment and health--with emphasis on world nutritional status].

PubMed

Suzuki, T

1993-12-01

Forthcoming global environmental changes threaten to endanger human survival through direct and indirect influences. In this paper, the contemporary world food supply situation and resultant nutritional status was first reviewed on by country and region. When compared with the nutritional energy requirement, countries with an inadequate food supply were concentrated in the developing world, in particular in some parts of Africa. The life expectancy at birth is clearly shorter in such countries, and peoples of African countries with an inadequate food supply have shorter life expectancies than other countries with a similar inadequacy. Global warning is likely to decrease food production in some parts of the world. According to the present estimation using various methods, a future crisis of food production may occur in African countries which are at present most vulnerable to food shortages, as well as in countries which are presently food exporters. Thus, a future crisis of human health conditions caused by the imbalance of food production and trade may be least avoidable in the region of present predicament.

Systems identification and application systems development for monitoring the physiological and health status of crewmen in space

NASA Technical Reports Server (NTRS)

Leonard, J. I.; Furukawa, S.; Vannordstrand, P. C.

1975-01-01

The use of automated, analytical techniques to aid medical support teams is suggested. Recommendations are presented for characterizing crew health in terms of: (1) wholebody function including physiological, psychological and performance factors; (2) a combination of critical performance indexes which consist of multiple factors of measurable parameters; (3) specific responses to low noise level stress tests; and (4) probabilities of future performance based on present and periodic examination of past performance. A concept is proposed for a computerized real time biomedical monitoring and health care system that would have the capability to integrate monitored data, detect off-nominal conditions based on current knowledge of spaceflight responses, predict future health status, and assist in diagnosis and alternative therapies. Mathematical models could play an important role in this approach, especially when operating in a real time mode. Recommendations are presented to update the present health monitoring systems in terms of recent advances in computer technology and biomedical monitoring systems.

On the development status of high performance silicon pore optics for future x-ray telescopes

NASA Astrophysics Data System (ADS)

Kraft, Stefan; Collon, M.; Günther, R.; Partapsing, R.; Beijersbergen, M.; Bavdaz, M.; Lumb, D.; Peacock, A.; Wallace, K.

2017-11-01

Silicon pore optics have been proposed earlier as modular optical X-ray units in large Wolter-I telescopes that would match effective area and resolution requirements imposed by missions such as XEUS. Since then the optics have been developed further and the feasibility of the production of high-performance pore optics has been demonstrated. Optimisation of both the production and the assembly process allowed the generation of optics with larger areas with improved imaging performance. Silicon pore optics can now be manufactured with properties required for future X-ray telescopes. A suitable design that allows the implementation of pore optics into X-ray Optical Units in Wolter-I configuration was recently derived including an appropriate telescope mounting structure with interfaces for the individual components. The development status, the achieved performance and the requirements regarding future mirror production, optics assembly and related metrology for its characterisation are presented.

Life-Course Transitions Among Adolescents With and Without Disabilities

PubMed Central

Shandra, Carrie L.

2015-01-01

Research on adolescents suggests that young people are able to form reasonable expectations about future life-course transitions—and that these expectations are predictive of future outcomes. However, less is known about how these expectations might vary for adolescents with disabilities, who might face additional challenges when transitioning to adulthood. The present study addresses this gap in the literature by using nationally representative data from the National Longitudinal Survey of Youth (NLSY97) to suggest that young people's expectations about pregnancy, parenthood, education, and employment do vary according to disability status. Furthermore, disability status conditions the relationship between these expectations and their future outcomes. In general, adolescents with disabilities are more proficient in the prediction of educational outcomes than employment or pregnancy outcomes. However, their expectations about education are significantly lower—and expectations about teenage parenthood much higher—than those of adolescents without disabilities. PMID:25926707

Overview and future direction for blackbody solar-pumped lasers

NASA Technical Reports Server (NTRS)

Deyoung, R. J.

1988-01-01

A review of solar-pumped blackbody lasers is given which addresses their present status and suggests future research directions. The blackbody laser concept is one system proposed to scale to multimegawatt power levels for space-to-space power transmissions for such applications as onboard spacecraft electrical or propulsion needs. Among the critical technical issues are the scalability to high powers and the laser wavelength which impacts the transmission optics size as well as the laser-to-electric converter at the receiver. Because present blackbody solar-pumped lasers will have laser wavelengths longer than 4 microns, simple photovoltaic converters cannot be used, and transmission optics will be large. Thus, future blackbody laser systems should emphasize near visible laser wavelengths.

2009-12-01

The impact of prenatal nutritional status, assessed through birth weight (BW) and their effects in the short, medium and long-term on nutritional status, cognitive development and job status in the adult life, has been a problem of interest for several researchers; as regards, some of these report a positive and significant association between these variables and others do not find any relation. Children with insufficient, low or very low BW despite the early more deteriorate nutritional status should present higher risk for brain maturation, failure cognitive development and lowered head circumference which implies both lowered brain volume and intellectual development. In the short and medium-term, this situation damages the learning process at school-age, while in the long-term this might condition the quality of jobs. At present, the body of knowledge pinpoints that findings related to these associations is not conclusive verifying a great controversy in these matters. This review article has the purpose of analyzing the current evidence, in order to stimulate research about to these aspects which are relevant for child development and their future life.

Multiple abiotic stressors affect the ecological status of water bodies. The status of waterbodies in the Ebro catchment (NE Spain) is evaluated using the biological quality elements (BQEs) of diatoms, invertebrates and macrophytes. The multi-stressor influence on the three BQEs was evaluated using the monitoring dataset available from the catchment water authority. Nutrient concentrations, especially total phosphorus (TP), affected most of the analyzed BQEs, while changes in mean discharge, water temperature, or river morphology did not show significant influences. Linear statistical models were used to evaluate the change of water bodies' ecological status under different combinations of future socioeconomic and climate scenarios. Changes in land use, rainfall, water temperature, mean discharge, TP and nitrate concentrations were modeled according to the future scenarios. These revealed an evolution of the abiotic stressors that could lead to a general decrease in the ecosystem quality of water bodies within the Ebro catchment. This deterioration was especially evidenced on the diatoms and invertebrate biological indices, mainly because of the foreseen increase in TP concentrations. Water bodies located in the headwaters were seen as the most sensitive to future changes. Copyright © 2018 The Author(s). Published by Elsevier B.V. All rights reserved.

Proceedings of the First Biennial Space Biomedical Investigators' Workshop

NASA Technical Reports Server (NTRS)

1999-01-01

The First Biennial Space Biomedical Investigators' Workshop, held January 11-13, 1999, was unique in that it assembled, for the first time, a broad cross section of NASA-funded biomedical researchers to present the current status of their projects and their plans for future investigations. All principal investigators with active, or recently-completed ground-based projects in NASA's Biomedical Research and Countermeasures Program that were funded through NASA's Office of Life and Microgravity Sciences and Applications were invited. Included were individual investigators funded through NASA Research Announcements, investigators with NASA Specialized Centers of Research and Training, investigators with the recently established National Space Biomedical Research Institute (NSBRI), and NASA civil servant investigators. Seventy-seven percent of all eligible projects were presented at the workshop. Thus, these Proceedings should provide a useful snapshot of the status of NASA-funded space biomedical research as of January 1999. An important workshop objective was to achieve free and open communication among the presenting investigators. Therefore, presentation of new and incomplete results, as well as hypotheses and ideas for future research, was encouraged. Comments and constructive criticisms from the presenters' colleagues were also encouraged. These ground rules resulted in many lively and useful discussions, during both the presentation sessions and informal evening gatherings and breaks.

Bioinorganic modeling chemistry of carbon monoxide dehydrogenases: description of model complexes, current status and possible future scopes.

PubMed

Majumdar, Amit

2014-08-28

Carbon monoxide dehydrogenases (CODHs) use CO as their sole source of carbon and energy and are found in both aerobic and anaerobic carboxidotrophic bacteria. Reversible transformation of CO to CO2 is catalyzed by a bimetallic [Mo-(μ2-S)-Cu] system in aerobic and by a highly asymmetric [Ni-Fe-S] cluster in anaerobic CODH active sites. The CODH activity in the microorganisms effects the removal of almost 10(8) tons of CO annually from the lower atmosphere and earth and thus help to maintain a sub-toxic concentration of CO. Despite an appreciable amount of work, the mechanism of CODH activity is not clearly understood yet. Moreover, biomimetic chemistry directed towards the active sites of CODHs faces several synthetic challenges. The synthetic problems associated with the modeling chemistry and strategies adopted to overcome those problems are discussed along with their limitations. A critical analysis of the exciting results delineating the present status of CODH modeling chemistry and its future prospects are presented.

2018-06-01

The growing demand for biotechnological products against limited metabolic capacity of industrially used microorganisms has led to an increased interest on strain-improvement over the last several decades, which aimed to enhance metabolite yield, substrate uptake and tolerance of the strains. Among a few techniques of strain-improvement, genome shuffling is the most recent and promising approach used for rapid strain-improvement that can yield a new strain by combining whole genomes of multi-parental microorganisms using the principles of protoplast fusion. Genome shuffling has brought a major breakthrough in the strain-improvement concept as it is found to be effective and reliable for expressing complex phenotypes. This review will discuss the technical aspects and applications of genome shuffling for various industrial strains to present its current status and recent progress. In the concluding remarks, a summary will be presented focusing on the major challenges and future outlooks of this technology. Copyright © 2018 Elsevier Ltd. All rights reserved.

Status of the Magma Energy Project

NASA Astrophysics Data System (ADS)

Dunn, J. C.

The current magma energy project is assessing the engineering feasibility of extracting thermal energy directly from crustal magma bodies. The estimated size of the U.S. resource (50,000 to 500,000 quads) suggests a considerable potential impact on future power generation. In a previous seven-year study, we concluded that there are no insurmountable barriers that would invalidate the magma energy concept. Several concepts for drilling, energy extraction, and materials survivability were successfully demonstrated in Kilauea Iki lava lake, Hawaii. The present program is addressing the engineering design problems associated with accessing magma bodies and extracting thermal energy for power generation. The normal stages for development of a geothermal resource are being investigated: exploration, drilling and completions, production, and surface power plant design. Current status of the engineering program and future plans are described.

Use of Future Scenarios as a Pedagogical Approach for Science Teacher Education

NASA Astrophysics Data System (ADS)

Paige, Kathryn; Lloyd, David

2016-04-01

Futures studies is usually a transdisciplinary study and as such embraces the physical world of the sciences and system sciences and the subjective world of individuals and cultures, as well as the time dimension—past, present and futures. Science education, where student interests, opportunities and challenges often manifest themselves, can provide a suitable entry point for futures work. In this paper, we describe how we have used futures themes, concepts and techniques both implicitly and explicitly in our undergraduate middle school teacher education courses and, in particular, science curriculum and general studies courses. Taking a critical orientation to the past and the present in these courses enables the future to be more than a mere reproduction of the status quo and opens up a range of possible futures in the areas of current interest. For example, having studied middle school teaching and learning in mathematics and science, students explore the past, present and possible future of a natural part of a university campus. In a general studies course on the science of the Earth's atmosphere, students construct a normative futures scenario on living in a changing climate. One way to gain insight into an uncertain future is to construct scenarios. This technique has been used since the 1970s to bring issues of environment and development—areas with strong science content—to the attention of both scientists and policymakers.

Researching the impact of oral health on diet and nutritional status: methodological issues.

Assessment of the impact of dental function on diet and nutritional status requires robust methodologies and a standardised approach to increase accuracy of results and to facilitate cross study comparisons. The objectives of this paper are: to report the outcomes of a consensus workshop that critically reviewed publications reporting on dietary methodologies in relation to the impact of oral health on nutrition; to highlight future directions for research and; to make recommendations for appropriate use of methodologies for future research. Data relevant to nutrition and dental status published from 1980 to 2005 in English were presented at the consensus workshop for discussion and appraisal. Relevant papers were retrieved through PubMed. Relevant texts were obtained from the library at Newcastle University, UK. A purposive sample of original articles that illustrated the application of a range of nutritional methodologies to the study of oral health impacts was identified. Original flagship texts on nutritional methodologies were reviewed. Numerous studies have shown an association between loss of teeth and inferior diet. Further research is required to elucidate the impact of novel approaches to prosthetic rehabilitation and the impact of contemporaneous dietary and dental intervention on diet, nutritional status, disease progression and quality of life. The recommendation of the consensus workshop was that future studies should adopt a comprehensive approach to the assessment of nutrition that encompasses measurement of diet, body composition, biochemical indices of intake and levels of nutrients, and functional biomarkers of disease.

The Role of a Relative Age Effect in the 7th International Children’s Winter Games 2016 and the Influence of Biological Maturity Status on Selection

PubMed Central

Müller, Lisa; Hildebrandt, Carolin; Raschner, Christian

2017-01-01

The aim of this study was to analyse the role of a relative age effect (RAE) and to investigate the influence of biological maturity status on the RAE at the 7th International Children`s Winter Games. The birth dates of all 572 participants (365 males, 207 females) were analysed, and the biological maturity status of 384 athletes (243 males, 141 females) was assessed by the age at peak height velocity (APHV) method. A RAE was present in the total sample (χ2 = 67.81; p < 0.001), and among both male (χ2 = 49.02; p < 0.001) and female athletes (χ2 = 37.00; p < 0.001) as well as for strength- (χ2 = 56.46; p < 0.001), endurance- (χ2 = 20.48; p = 0.039) and technique-related types of sports (χ2 = 20.48; p = 0.041). No significant differences in biological maturity status were present between the male athletes of single relative age quarters. Among the female athletes a significant difference was present (F = 5.94, p < 0.001); relatively younger female athletes had significantly lower values in the APHV, which indicated that they were maturing earlier. However, when dividing the athletes into normal, early and late maturing athletes, it could be seen that among the relatively younger athletes, hardly any late maturing athletes were present. These findings revealed that relatively younger athletes seemed to only have a chance for selection if they were early maturing, whereas relatively older athletes had an increased likelihood for selection independent of their biological maturity status. In the future, the relative age and the biological maturity status should be considered in the talent development system for various types of winter sport, to contribute to more fairness and to not discriminate against relatively younger and less mature athletes. Key points The relative age strongly influenced the participation rate at the 7th ICG in 2016. A highly significant RAE was present among male and female participants and among athletes of all three groups of sport disciplines: strength-, endurance- and technique-related types of sport. A significant influence of the biological maturity status on the selection was present among female participants – relatively younger female athletes were more mature than relatively older athletes. Relatively younger male and female athletes seem to only have a chance for selection for the Games if they are early maturing, whereas relatively older athletes have an increased likelihood for selection independent of their biological maturity status. In the future, the biological maturity status and the relative age should be considered in the talent development system for various types of winter sport, to contribute to more fairness and to not discriminate against relatively younger and less mature athletes.

Present status and future directions of the Mayo/IBM PACS project

NASA Astrophysics Data System (ADS)

Morin, Richard L.; Forbes, Glenn S.; Gehring, Dale G.; Salutz, James R.; Pavlicek, William

1991-07-01

This joint project began in 1988 and was motivated by the need to develop an alternative to the archival process in place at that time (magnetic tape) for magnetic resonance imaging and neurological computed tomography. In addition, this project was felt to be an important step in gaining the necessary clinical experience for the future implementation of various aspects of electronic imaging. The initial phase of the project was conceived and developed to prove the concept, test the fundamental components, and produce performance measurements for future work. The key functions of this phase centered on attachment of imaging equipment (GE Signa) and archival processes using a non-dedicated (institutionally supplied) local area network (LAN). Attachment of imaging equipment to the LAN was performed using commercially available devices (Ethernet, PS/2, Token Ring). Image data were converted to ACR/NEMA format with retention of the vendor specific header information. Performance measurements were encouraging and led to the design of following projects. The second phase has recently been concluded. The major features of this phase have been to greatly expand the network, put the network into clinical use, establish an efficient and useful viewing station, include diagnostic reports in the archive data, provide wide area network (WAN) capability via ISDN, and establish two-way real-time video between remote sites. This phase has heightened both departmental and institutional thought regarding various issues raised by electronic imaging. Much discussion regarding both present as well as future archival processes has occurred. The use of institutional LAN resources has proven to be adequate for the archival function examined thus far. Experiments to date have shown that use of dedicated resources will be necessary for retrieval activities at even a basic level. This report presents an overview of the background present status and future directions of the project.

Impact of climate change on water resources status: A case study for Crete Island, Greece

NASA Astrophysics Data System (ADS)

Koutroulis, Aristeidis G.; Tsanis, Ioannis K.; Daliakopoulos, Ioannis N.; Jacob, Daniela

2013-02-01

SummaryAn assessment of the impact of global climate change on the water resources status of the island of Crete, for a range of 24 different scenarios of projected hydro-climatological regime is presented. Three "state of the art" Global Climate Models (GCMs) and an ensemble of Regional Climate Models (RCMs) under emission scenarios B1, A2 and A1B provide future precipitation (P) and temperature (T) estimates that are bias adjusted against observations. The ensemble of RCMs for the A1B scenario project a higher P reduction compared to GCMs projections under A2 and B1 scenarios. Among GCMs model results, the ECHAM model projects a higher P reduction compared to IPSL and CNCM. Water availability for the whole island at basin scale until 2100 is estimated using the SAC-SMA rainfall-runoff model And a set of demand and infrastructure scenarios are adopted to simulate potential water use. While predicted reduction of water availability under the B1 emission scenario can be handled with water demand stabilized at present values and full implementation of planned infrastructure, other scenarios require additional measures and a robust signal of water insufficiency is projected. Despite inherent uncertainties, the quantitative impact of the projected changes on water availability indicates that climate change plays an important role to water use and management in controlling future water status in a Mediterranean island like Crete. The results of the study reinforce the necessity to improve and update local water management planning and adaptation strategies in order to attain future water security.

Selby, J.; Carbaugh, E.H.; Lynch, T.P.

1993-09-01

We have attempted to characterize the current and future status of in vivo and in vitro measurement programs coupled with the associated radioanalytical methods and workplace monitoring. Developments in these areas must be carefully integrated by internal dosimetrists, radiochemists and field health physicists. Their goal should be uniform improvement rather than to focus on one specific area (e.g., dose modeling) to the neglect of other areas where the measurement capabilities are substantially less sophisticated and, therefore, the potential source of error is greatest.

Status, emotional displays, and the relationally-based evaluation of criminals and their behavior.

PubMed

Dilks, Lisa M; McGrimmon, Tucker S; Thye, Shane R

2015-03-01

This research uses status characteristics theory to expand our knowledge of the effects of status variables (e.g., race, education) and emotional displays on the antecedents of sentencing - evaluations of offender dangerousness and offense seriousness. We present a theoretical formulation that combines three areas of status characteristics research - reward expectations, individual evaluative settings and valued personal characteristics. The result is a quantitative measure that aggregates relative differences in demographic and emotional characteristics between offenders and their victims. The significance of this expectation advantage measure (e) in predicting evaluations of offender dangerousness and offense severity is tested using data from a vignette study. We find empirical support that expectation advantage significantly predicts these sentencing antecedents but not sentencing outcomes directly. We conclude by discussing the implications of our findings for future status and criminological research. Copyright © 2014 Elsevier Inc. All rights reserved.

Following the 2013 update of the European Strategy for Particle Physics, the international Future Circular Collider (FCC) Study has been launched by CERN as host institute, to design an energy frontier hadron collider (FCC-hh) in a new 80-100 km tunnel with a centre-of-mass energy of about 100 TeV, an order of magnitude beyond the LHC's, as a long-term goal. The FCC study also includes the design of a 90-350 GeV high-luminosity lepton collider (FCC-ee) installed in the same tunnel, serving as Higgs, top and Z factory, as a potential intermediate step, as well as an electron-proton collider option (FCC-he). The physics cases for such machines will be assessed and concepts for experiments will be developed in time for the next update of the European Strategy for Particle Physics by the end of 2018. The presentation will summarize the status of machine designs and parameters and discuss the essential technical components to be developed in the frame of the FCC study. Key elements are superconducting accelerator-dipole magnets with a field of 16 T for the hadron collider and high-power, high-efficiency RF systems for the lepton collider. In addition the unprecedented beam power presents special challenges for the hadron collider for all aspects of beam handling and machine protection. First conclusions of geological investigations and implementation studies will be presented. The status of the FCC collaboration and the further planning for the study will be outlined.

The ILLIAC IV memory system: Current status and future possibilities

The future needs of researchers who will use the Illiac were examined and the requirements they will place on the memory system were evaluated. Various alternatives to replacing critical memory components were considered with regard to cost, risk, system impact, software requirements, and implementation schedules. The current system, its performance and status, and the limitations it places on possible enhancements are discussed as well as the planned enhancements to the Illiac processor. After a brief technology survey, different implementations are presented for each system memory component. Three different memory systems are proposed to meet the identified needs of the Illiac user community. These three alternatives differ considerably with respect to storage capacity and accessing capabilities, but they all offer significant improvements over the current system. The proposed systems and their relative merits are analyzed.

How Social Status Shapes Person Perception and Evaluation: A Social Neuroscience Perspective.

PubMed

Mattan, Bradley D; Kubota, Jennifer T; Cloutier, Jasmin

2017-05-01

Inferring the relative rank (i.e., status) of others is essential to navigating social hierarchies. A survey of the expanding social psychological and neuroscience literatures on status reveals a diversity of focuses (e.g., perceiver vs. agent), operationalizations (e.g., status as dominance vs. wealth), and methodologies (e.g., behavioral, neuroscientific). Accommodating this burgeoning literature on status in person perception, the present review offers a novel social neuroscientific framework that integrates existing work with theoretical clarity. This framework distinguishes between five key concepts: (1) strategic pathways to status acquisition for agents, (2) status antecedents (i.e., perceptual and knowledge-based cues that confer status rank), (3) status dimensions (i.e., domains in which an individual may be ranked, such as wealth), (4) status level (i.e., one's rank along a given dimension), and (5) the relative importance of a given status dimension, dependent on perceiver and context characteristics. Against the backdrop of this framework, we review multiple dimensions of status in the nonhuman and human primate literatures. We then review the behavioral and neuroscientific literatures on the consequences of perceived status for attention and evaluation. Finally, after proposing a social neuroscience framework, we highlight innovative directions for future social status research in social psychology and neuroscience.

Predicting the effect of disability on employment status and income.

PubMed

Randolph, Diane Smith

2004-01-01

Research shows that participation in employment contributes to life satisfaction for persons with disabilities [18]. Title I of the Americans with Disabilities Act (ADA) sought to prohibit discrimination against persons with disabilities in the workplace, however, the ADA's effectiveness remains controversial. This research utilizes data from the disability supplement of the 2000 Behavioral Risk Factor Surveillance System to examine the impact of disability status on predicting employment status and income. Confounding variables such as gender, age, educational level, race and marital/parental status are examined regarding their influence on results. Results from analysis utilizing zero-order correlation, linear and logistic regression analysis techniques revealed that disability status has a significant predictive effect on inability to work. Furthermore, results continue to show that despite legislation, the higher the level of disability, the lower the employment status (those employed for wages) and income. Finally, disability status, coupled with being female or decreased educational level, consistently shows significance in predicting lower employment status and income than men or non-minorities with disabilities. Future research opportunities and policy implications are discussed with regard to the results presented.

Operational present status and reliability analysis of the upgraded EAST cryogenic system

NASA Astrophysics Data System (ADS)

Zhou, Z. W.; Y Zhang, Q.; Lu, X. F.; Hu, L. B.; Zhu, P.

2017-12-01

Since the first commissioning in 2005, the cryogenic system for EAST (Experimental Advanced Superconducting Tokamak) has been cooled down and warmed up for thirteen experimental campaigns. In order to promote the refrigeration efficiencies and reliability, the EAST cryogenic system was upgraded gradually with new helium screw compressors and new dynamic gas bearing helium turbine expanders with eddy current brake to improve the original poor mechanical and operational performance from 2012 to 2015. Then the totally upgraded cryogenic system was put into operation in the eleventh cool-down experiment, and has been operated for the latest several experimental campaigns. The upgraded system has successfully coped with various normal operational modes during cool-down and 4.5 K steady-state operation under pulsed heat load from the tokamak as well as the abnormal fault modes including turbines protection stop. In this paper, the upgraded EAST cryogenic system including its functional analysis and new cryogenic control networks will be presented in detail. Also, its operational present status in the latest cool-down experiments will be presented and the system reliability will be analyzed, which shows a high reliability and low fault rate after upgrade. In the end, some future necessary work to meet the higher reliability requirement for future uninterrupted long-term experimental operation will also be proposed.

Time-of-Flight Polarized Neutron Reflectometry on PLATYPUS: Status and Future Developments

NASA Astrophysics Data System (ADS)

Saerbeck, T.; Cortie, D. L.; Brück, S.; Bertinshaw, J.; Holt, S. A.; Nelson, A.; James, M.; Lee, W. T.; Klose, F.

Time-of-flight (ToF) polarized neutron reflectometry enables the detailed investigation of depth-resolved magnetic structures in thin film and multilayer magnetic systems. The general advantage of the time-of-flight mode of operation over monochromatic instruments is a decoupling of spectral shape and polarization of the neutron beam with variable resolution. Thus, a wide Q-range can be investigated using a single angle of incidence, with resolution and flux well-adjusted to the experimental requirement. Our paper reviews the current status of the polarization equipment of the ToF reflectometer PLATYPUS and presents first results obtained on stratified Ni80Fe20/α-Fe2O3 films, revealing the distribution of magnetic moments in an exchange bias system. An outlook on the future development of the PLATYPUS polarization system towards the implementation of a polarized 3He cell is presented and discussed with respect to the efficiency and high Q-coverage up to 1 Å-1 and 0.15 Å-1 in the vertical and lateral momentum transfer, respectively.

The influence of mortality and socioeconomic status on risk and delayed rewards: a life history theory approach.

Griskevicius, Vladas; Tybur, Joshua M; Delton, Andrew W; Robertson, Theresa E

2011-06-01

Why do some people take risks and live for the present, whereas others avoid risks and save for the future? The evolutionary framework of life history theory predicts that preferences for risk and delay in gratification should be influenced by mortality and resource scarcity. A series of experiments examined how mortality cues influenced decisions involving risk preference (e.g., $10 for sure vs. 50% chance of $20) and temporal discounting (e.g., $5 now vs. $10 later). The effect of mortality depended critically on whether people grew up in a relatively resource-scarce or resource-plentiful environment. For individuals who grew up relatively poor, mortality cues led them to value the present and gamble for big immediate rewards. Conversely, for individuals who grew up relatively wealthy, mortality cues led them to value the future and avoid risky gambles. Overall, mortality cues appear to propel individuals toward diverging life history strategies as a function of childhood socioeconomic status, suggesting important implications for how environmental factors influence economic decisions and risky behaviors. 2011 APA, all rights reserved

HOW TO DETERMINE THE NUTRITIONAL STATUS OF PRETERM BABIES?--REVIEW OF THE LITERATURE.

PubMed

Mól, Nina; Kwinta, Przemko

2015-01-01

Prematurity is a high risk factor threatening the well-being of newborns and their somatic and psychological development in the future. Preterm babies need special medical care in which proper nutrition and metabolic control play an evident role. Our review presents the current knowledge concerning the clinical value of different methods investigated in the neonatal unit setting, including: protein markers of nutritional status (albumin,prealbumin, transferrin, and Retinol Binding Protein (RBP) and hormonal markers of nutritional status (somatomedin C, visfatin and ghrelin). Moreover, there is a discussion of the methods used for evaluating body composition. A variety of different techniques based on the physical properties of organisms was tested on neonates, e.g. the Dual Energy X-ray Absorptiometry (DEXA) method and Bioelectrical Impedance Analysis (BIA). Based on the review of the literature, we can speculate that none of the above methods represents a good single marker of the babies' nutritional status, or a prognostic factor for the future development of premature infants and infants born with IUGR. A combination of several methods from different groups seems to be a promising possibility. It is critical to continue looking for markers that will in a simple and efficient way help to optimize the correct nutritional therapy in infants with IUGR and those who were born prematurely.

2016-02-01

In the present study, we tested whether the five identity statuses of the original Meeus-Crocetti model could be extracted in a Turkish sample. Their three-factor model of identity was used to examine identity formation. Participants were 1201 (59.6% females) youth aged between 12 and 24 years (Mage = 17.53 years, SDage = 3.25). Findings revealed that the five identity statuses extracted in previous studies (Crocetti, Rubini, Luyckx, & Meeus, 2008; Crocetti, Schwartz, Fermani, Klimstra, & Meeus, 2012) also emerged in a sample of Turkish adolescents and emerging adults. Findings indicated that gender and age affected the distribution of the individuals among the five identity statuses. Furthermore, individuals in the five identity statuses represented distinct profiles according to personality and self characteristics, problem behaviors and well-being, and interpersonal and group relationships. Finally, the status × age interactions indicated that the searching moratorium status became more problematic with age. Implications and suggestions for future research are also discussed.

In the eye of the beholder: Can counter-stereotypes change perceptions of older adults' social status?

PubMed

Robertson, Deirdre A; Weiss, David

2017-09-01

Negative age-related stereotypes often entail the perception that older adults have a lower social status than middle-aged adults. We hypothesized that older adults are perceived to have lower social status because they are less likely to be seen in prestigious occupational positions. People tend to infer general assumptions about group characteristics from exemplars. According to this, presenting a stereotype-inconsistent exemplar (i.e., older person in a high-status position) should change perceptions of older adults' social status. Study 1 (60 countries, N = 86,026, 18-99 years) showed that people in countries with an older relative to a younger political leader do not perceive as great a decline in social status from middle-aged to older adults. Study 2 (N = 131; 19-74 years) tested the causal link demonstrating that participants exposed to older exemplars holding a prestigious occupational position were significantly more likely to rate older adults as having a relative higher social status. We discuss implications for future interventions to change negative age-related stereotypes. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Violence exposure among children with disabilities.

PubMed

Sullivan, Patricia M

2009-06-01

The focus of this paper is children with disabilities exposed to a broad range of violence types including child maltreatment, domestic violence, community violence, and war and terrorism. Because disability research must be interpreted on the basis of the definitional paradigm employed, definitions of disability status and current prevalence estimates as a function of a given paradigm are initially considered. These disability paradigms include those used in federal, education, juvenile justice, and health care arenas. Current prevalence estimates of childhood disability in the U.S. are presented within the frameworks of these varying definitions of disability status in childhood. Summaries of research from 2000 to 2008 on the four types of violence victimization addressed among children with disabilities are presented and directions for future research suggested.

Nuclear data for medical applications: An overview of present status and future needs

2017-09-01

A brief overview of nuclear data required for medical applications is given. The major emphasis is on radionuclides for internal applications, both for diagnosis and therapy. The status of the presently available data is discussed and some of the emerging needs are outlined. Most of the needs are associated with the development of non-standard positron emitters and novel therapeutic radionuclides. Some new developments in application of radionuclides, e.g. theranostic approach, multimode imaging, radionanoparticles, etc. are described and the related nuclear data needs are discussed. The possible use of newer irradiation technologies for medical radionuclide production, e.g. intermediate energy charged-particle accelerators, high-power electron accelerators for photon production, and spallation neutron sources, will place heavy demands on nuclear data.

Incorporating population viability models into species status assessment and listing decisions under the U.S. Endangered Species Act

2017-01-01

Assessment of a species' status is a key part of management decision making for endangered and threatened species under the U.S. Endangered Species Act. Predicting the future state of the species is an essential part of species status assessment, and projection models can play an important role in developing predictions. We built a stochastic simulation model that incorporated parametric and environmental uncertainty to predict the probable future status of the Sonoran desert tortoise in the southwestern United States and North Central Mexico. Sonoran desert tortoise was a Candidate species for listing under the Endangered Species Act, and decision makers wanted to use model predictions in their decision making process. The model accounted for future habitat loss and possible effects of climate change induced droughts to predict future population growth rates, abundances, and quasi-extinction probabilities. Our model predicts that the population will likely decline over the next few decades, but there is very low probability of quasi-extinction less than 75 years into the future. Increases in drought frequency and intensity may increase extinction risk for the species. Our model helped decision makers predict and characterize uncertainty about the future status of the species in their listing decision. We incorporated complex ecological processes (e.g., climate change effects on tortoises) in transparent and explicit ways tailored to support decision making processes related to endangered species.

Analysis of regional natural flow for evaluation of flood risk according to RCP climate change scenarios

Lee, J. Y.; Chae, B. S.; Wi, S.; KIm, T. W.

2017-12-01

Various climate change scenarios expect the rainfall in South Korea to increase by 3-10% in the future. The future increased rainfall has significant effect on the frequency of flood in future as well. This study analyzed the probability of future flood to investigate the stability of existing and new installed hydraulic structures and the possibility of increasing flood damage in mid-sized watersheds in South Korea. To achieve this goal, we first clarified the relationship between flood quantiles acquired from the flood-frequency analysis (FFA) and design rainfall-runoff analysis (DRRA) in gauged watersheds. Then, after synthetically generating the regional natural flow data according to RCP climate change scenarios, we developed mathematical formulas to estimate future flood quantiles based on the regression between DRRA and FFA incorporated with regional natural flows in unguaged watersheds. Finally, we developed a flood risk map to investigate the change of flood risk in terms of the return period for the past, present, and future. The results identified that the future flood quantiles and risks would increase in accordance with the RCP climate change scenarios. Because the regional flood risk was identified to increase in future comparing with the present status, comprehensive flood control will be needed to cope with extreme floods in future.

This document contains the proceedings of the Workshop on Intelligent Agents and Their Potential for Future Design and Synthesis Environment, held at NASA Langley Research Center, Hampton, VA, September 16-17, 1998. The workshop was jointly sponsored by the University of Virginia's Center for Advanced Computational Technology and NASA. Workshop attendees came from NASA, industry and universities. The objectives of the workshop were to assess the status of intelligent agents technology and to identify the potential of software agents for use in future design and synthesis environment. The presentations covered the current status of agent technology and several applications of intelligent software agents. Certain materials and products are identified in this publication in order to specify adequately the materials and products that were investigated in the research effort. In no case does such identification imply recommendation or endorsement of products by NASA, nor does it imply that the materials and products are the only ones or the best ones available for this purpose. In many cases equivalent materials and products are available and would probably produce equivalent results.

Inhomogeneous cosmology and backreaction: Current status and future prospects

NASA Astrophysics Data System (ADS)

Bolejko, Krzysztof; Korzyński, Mikołaj

Astronomical observations reveal hierarchical structures in the universe, from galaxies, groups of galaxies, clusters and superclusters, to filaments and voids. On the largest scales, it seems that some kind of statistical homogeneity can be observed. As a result, modern cosmological models are based on spatially homogeneous and isotropic solutions of the Einstein equations, and the evolution of the universe is approximated by the Friedmann equations. In parallel to standard homogeneous cosmology, the field of inhomogeneous cosmology and backreaction is being developed. This field investigates whether small scale inhomogeneities via nonlinear effects can backreact and alter the properties of the universe on its largest scales, leading to a non-Friedmannian evolution. This paper presents the current status of inhomogeneous cosmology and backreaction. It also discusses future prospects of the field of inhomogeneous cosmology, which is based on a survey of 50 academics working in the field of inhomogeneous cosmology.

The use of biopharmaceutic classification of drugs in drug discovery and development: current status and future extension.

PubMed

Lennernäs, Hans; Abrahamsson, Bertil

2005-03-01

Bioavailability (BA) and bioequivalence (BE) play a central role in pharmaceutical product development and BE studies are presently being conducted for New Drug Applications (NDAs) of new compounds, in supplementary NDAs for new medical indications and product line extensions, in Abbreviated New Drug Applications (ANDAs) of generic products and in applications for scale-up and post-approval changes. The Biopharmaceutics Classification System (BCS) has been developed to provide a scientific approach for classifying drug compounds based on solubility as related to dose and intestinal permeability in combination with the dissolution properties of the oral immediaterelease (IR) dosage form. The aim of the BCS is to provide a regulatory tool for replacing certain BE studies by accurate in-vitro dissolution tests. The aim of this review is to present the status of the BCS and discuss its future application in pharmaceutical product development. The future application of the BCS is most likely increasingly important when the present framework gains increased recognition, which will probably be the case if the BCS borders for certain class II and III drugs are extended. The future revision of the BCS guidelines by the regulatory agencies in communication with academic and industrial scientists is exciting and will hopefully result in an increased applicability in drug development. Finally, we emphasize the great use of the BCS as a simple tool in early drug development to determine the rate-limiting step in the oral absorption process, which has facilitated the information between different experts involved in the overall drug development process. This increased awareness of a proper biopharmaceutical characterization of new drugs may in the future result in drug molecules with a sufficiently high permeability, solubility and dissolution rate, and that will automatically increase the importance of the BCS as a regulatory tool over time.

　While the community-based integrated care systems are in the process of being structured currently, more and more community pharmacists want to learn physical assessment skills. However, no large-scale survey focusing on present implementation status and problems of physical assessment by community pharmacists has been conducted yet. Osaka has the 2nd highest number of community pharmacies in Japan now, and the population aged ≥65 years will be expected to become the 3rd highest in 2025. Thus, Osaka can become a national leading model case for community pharmacists' activity in future home medical care. Therefore, this study aimed to reveal the present implementation status and problems of physical assessment by community pharmacists in Osaka, especially focusing on vital-signs. The questionnaires were sent to all the 3571 insurance pharmacies belonging to the Osaka Pharmaceutical Association and 871 pharmacies responded. Many pharmacists recognized the necessity for vital-signs measurement by pharmacists in home medical care (81.5% of pharmacies that offered home medical care and 75.4% of pharmacies that did not offer one). However, the proportion of pharmacies that conduct vital-signs measurement in home medical care was 18.7%, therefore, it was suggested that the present problem is "many pharmacists cannot conduct vital-signs measurement, although they think it should be conducted". Moreover, the most common reason for not measuring vital-signs was the lack of instruments, such as stethoscopes and sphygmomanometer (43.2%). This is the latest report with a large-scale sample, thus, it can serve as valuable knowledge in considering what pharmacists do for the future.

A method to combine observations and an ensemble of ecological models has been used to assess eutrophication. Using downscaled forcing from two GCMs under the A1B emission scenario, an assessment of the eutrophication status was made for a control (1970-2000) and a future climate (2070-2100) period. By using validation results from a hindcast to compute individual weights between the models, an assessment of eutrophication is done using a set of threshold values. The final classification distinguishes between three categories: problem area, potential problem area, and non-problem area, in accordance with current management practice as suggested by the Oslo and Paris Commissions (OSPAR) and the Helsinki Commission (HELCOM). For the control run the assessment indicates that the Kattegat, the Danish Straits, the Gulf of Finland, the Gotland Basin as well as main parts of the Arkona Basin, the Bornholm Basin, and the Baltic proper may be classified as problem areas. The main part of the North Sea and also the Skagerrak are non-problem areas while the main parts of the Gulf of Bothnia, Gulf of Riga and the entire southeastern continental coast of the North Sea may be classified as potential problem areas. In the future climate scenarios most of the previous potential problem areas in the Baltic Sea have become problem areas, except for the Bothnian Bay where the situation remain fairly unchanged. In the North Sea there seems to be no obvious changes in eutrophication status in the projected future climate.

NASAs Evolutionary Xenon Thruster (NEXT) project is developing next generation ion propulsion technologies to enhance the performance and lower the costs of future NASA space science missions. This is being accomplished by producing Engineering Model (EM) and Prototype Model (PM) components, validating these via qualification-level and integrated system testing, and preparing the transition of NEXT technologies to flight system development. This presentation is a follow-up to the NEXT project overviews presented in 2009-2010. It reviews the status of the NEXT project, presents the current system performance characteristics, and describes planned activities in continuing the transition of NEXT technology to a first flight. In 2013 a voluntary decision was made to terminate the long duration test of the NEXT thruster, given the thruster design has exceeded all expectations by accumulating over 50,000 hours of operation to demonstrate around 900 kg of xenon throughput. Besides its promise for upcoming NASA science missions, NEXT has excellent potential for future commercial and international spacecraft applications.

Patients who have undergone angioplasty experience difficulty modifying at-risk behaviors for subsequent cardiac events. The purpose of this study was to test whether an innovative approach to framing of risk, based on 'net present value' economic theory, would be more effective in behavioral intervention than the standard 'future value approach' in reducing cardiovascular morbidity and mortality following angioplasty. At baseline, all patients completed a health assessment, received an individualized risk profile and selected risk factors for modification. The intervention randomized patients into two varying methods for illustrating positive effects of behavior change. For the experimental group, each selected risk factor was assigned a numeric biologic age (the net present value) that approximated the relative potential to improve current health status and quality of life when modifying that risk factor. In the control group, risk reduction was framed as the value of preventing future health problems. Ninety-four percent of patients completed 2-year follow-up. There was no difference between the rates of death, stroke, myocardial infarction, Class II-IV angina or severe ischemia (on non-invasive testing) between the net present value group and the future value group. Our results show that a net present risk communication intervention did not result in significant differences in health outcomes.

Biomarkers for monitoring intestinal health in poultry: present status and future perspectives.

Intestinal health is determined by host (immunity, mucosal barrier), nutritional, microbial and environmental factors. Deficiencies in intestinal health are associated with shifts in the composition of the intestinal microbiome (dysbiosis), leakage of the mucosal barrier and/or inflammation. Since the ban on growth promoting antimicrobials in animal feed, these dysbiosis-related problems have become a major issue, especially in intensive animal farming. The economical and animal welfare consequences are considerable. Consequently, there is a need for continuous monitoring of the intestinal health status, particularly in intensively reared animals, where the intestinal function is often pushed to the limit. In the current review, the recent advances in the field of intestinal health biomarkers, both in human and veterinary medicine are discussed, trying to identify present and future markers of intestinal health in poultry. The most promising new biomarkers will be stable molecules ending up in the feces and litter that can be quantified, preferably using rapid and simple pen-side tests. It is unlikely, however, that a single biomarker will be sufficient to follow up all aspects of intestinal health. Combinations of multiple biomarkers and/or metabarcoding, metagenomic, metatranscriptomic, metaproteomic and metabolomic approaches will be the way to go in the future. Candidate biomarkers currently are being investigated by many research groups, but the validation will be a major challenge, due to the complexity of intestinal health in the field.

1998-01-01

A systematic methodology, Comprehensive Assessment for Tracking Community Health (CATCH), for analyzing the health status of communities has been under development at the University of South Florida since the early 1990s. CATCH draws 226 health status indicators from multiple data sources and uses an innovative comparative framework and weighted evaluation criteria to produce a rank-ordered list of community health problems. CATCH has been applied successfully in many Florida counties; focusing attention on high priority health issues and measuring the impact of health expenditures on community health status outcomes. Previously performed manually, we are using information technology (IT) to automate the CATCH methodology with a full-scale data warehouse, user-friendly forms and reports, and extended analysis and data mining capabilities. The automated system, CATCH/IT, will reduce the time to prepare community health status reports from months to days. In this paper, we present the current status of the project, along with the principal research and development issues and future directions of the project. PMID:9929220

Doucet, Jean

2003-01-01

Be it proteins, new superconductors, polymers or ferro-magnetic compounds, fundamental research is laying foundations for possible technical applications as well as industrial exploitation. At the ESRF, industrial companies can be involved in two main ways, depending on the type of research they are interested in. The first concerns beam time allocation for non-proprietary and fully-published research, the procedure is the same as for public laboratories. The second concerns the proprietary research, for which a fee is charged and where results are kept confidential. The use of synchrotron radiation for the characterisation of materials is certain to play a crucial role in the development of new materials in the close future. It is a policy of the ESRF that European industry should share the benefit of its facilities. A survey of the today industrial activity at the ESRF and of its perspective in near future is presented.

The prevalence of postpartum depression: the relative significance of three social status indices.

PubMed

Segre, Lisa S; O'Hara, Michael W; Arndt, Stephan; Stuart, Scott

2007-04-01

Little is known about the prevalence of clinically significant postpartum depression in women of varying social status. The purpose of the present study was to examine the prevalence of postpartum depression as a function of three indices of social status: income, education and occupational prestige. A sample of 4,332 postpartum women completed a demographic interview and the Inventory to Diagnose Depression, a self-report scale developed to identify a major depressive episode in accordance with DSM diagnostic criteria. Logistic regression was used to assess the relative significance of the three social status variables as risk factors for postpartum depression controlling for the effects of correlated demographic variables. In the logistic regression, income, occupational prestige, marital status, and number of children were significant predictors of postpartum depression controlling for the effects of other related demographic characteristics. The Wald Chi Square value for each of these significant predictors indicates that income was the strongest predictor. The prevalence of postpartum depression was significantly higher in financially poor relative to financially affluent women. Maternal depression screening programs targeting women who are financially poor are well placed. Future research is needed to replicate the present findings in a more ethnically diverse sample that includes the full age range of teenage mothers.

Cryogenic fluid management (CFM) is an important aspect in the design and operation of spacecraft propellant systems. Consequently, it represents a key technology in the development of future vehicles for orbital transfer, lunar transit and manned interplanetary (i.e., Mars) missions. Because of Marshall Space Flight Center's (MSFC's) leading role in the definition of such vehicles, the center is currently managing and conducting a variety of tests to support development of this technology. The purpose of this paper is to summarize these activities and present their status within the context of CFM technology requirements. The first section reviews MSFC's role, identifies the major emphases and thrusts of its program, and presents the overall schedule. The final part comprises the bulk of the report, and describes at length the objectives, approach and status of each project.

The global status of freshwater fish age validation studies and a prioritization framework for future research

USGS Publications Warehouse

Pope, Kevin L.; Hamel, Martin J.; Pegg, Mark A.; Spurgeon, Jonathan J.

2016-01-01

Age information derived from calcified structures is commonly used to estimate recruitment, growth, and mortality for fish populations. Validation of daily or annual marks on age structures is often assumed, presumably due to a lack of general knowledge concerning the status of age validation studies. Therefore, the current status of freshwater fish age validation studies was summarized to show where additional effort is needed, and increase the accessibility of validation studies to researchers. In total, 1351 original peer-reviewed articles were reviewed from freshwater systems that studied age in fish. Periodicity and age validation studies were found for 88 freshwater species comprising 21 fish families. The number of age validation studies has increased over the last 30 years following previous calls for more research; however, few species have validated structures spanning all life stages. In addition, few fishes of conservation concern have validated ageing structures. A prioritization framework, using a combination of eight characteristics, is offered to direct future age validation studies and close the validation information gap. Additional study, using the offered prioritization framework, and increased availability of published studies that incorporate uncertainty when presenting research results dealing with age information are needed.

2012-12-01

BACKGROUND & HYPOTHESIS: Data on the clinical characteristics and outcome of patients presenting with acute coronary syndrome (ACS) according to their marital status is not clear. A total of 5334 patients presenting with ACS in 65 hospitals in 6 Middle East countries in the 2nd Gulf Registry of Acute Coronary Events (Gulf RACE-2) were studied according to their marital status (5024 married, 100 single, and 210 widowed patients). When compared to married patients, widowed patients were older and more likely to be female. Widowed patients were more likely to have diabetes mellitus, hypertension, history of heart failure, and peripheral vascular disease and were less likely to be tobacco users when compared to the other groups. Widowed patients were also more likely to present with atypical symptoms and have advanced Killip class. Widowed patients were more likely to present with non-ST-elevation myocardial infarction (NSTEMI) when compared to the other 2 groups. Widowed patients were more likely to have heart failure (P = 0.001), cardiogenic shock (P = 0.001), and major bleeding (P = 0.002) when compared to the other groups. No statistically significant difference was observed in regard to duration of hospital stay, door to needle time in STEMI patients, or cardiac arrhythmias between the various groups. Widowed patients had higher in-hospital, 30-day, and 1-year mortality rates (P = 0.001). Marital status was an independent predictor for in-hospital mortality. Widowed marital status was associated with worse cardiovascular risk profile, and worse in-hospital and 1-year outcome. Future work should be focused on whether the provision of psychosocial support will result in improved outcomes among this high-risk group. © 2012 Wiley Periodicals, Inc.

The Accelerator Physics Working Group addressed the worldwide R&D activities performed in support of future neutrino facilities. These studies cover R&D activities for Super Beam, Beta Beam and muon-based Neutrino Factory facilities. Beta Beam activities reported the important progress made, together with the research activity planned for the coming years. Discussion sessions were also organized jointly with other working groups in order to define common ground for the optimization of a future neutrino facility. Lessons learned from already operating neutrino facilities provide key information for the design of any future neutrino facility, and were also discussed in this meeting. Radiation damage, remote handling for equipment maintenance and exchange, and primary proton beam stability and monitoring were among the important subjects presented and discussed. Status reports for each of the facility subsystems were presented: proton drivers, targets, capture systems, and muon cooling and acceleration systems. The preferred scenario for each type of possible future facility was presented, together with the challenges and remaining issues. The baseline specification for the muon-based Neutrino Factory was reviewed and updated where required. This report will emphasize new results and ideas and discuss possible changes in the baseline scenarios of the facilities. A list of possible future steps is proposed that should be followed up at NuFact10.

2013-01-01

Robotic cardiac operations evolved from minimally invasive operations and offer similar theoretical benefits, including less pain, shorter length of stay, improved cosmesis, and quicker return to preoperative level of functional activity. The additional benefits offered by robotic surgical systems include improved dexterity and degrees of freedom, tremor-free movements, ambidexterity, and the avoidance of the fulcrum effect that is intrinsic when using long-shaft endoscopic instruments. Also, optics and operative visualization are vastly improved compared with direct vision and traditional videoscopes. Robotic systems have been utilized successfully to perform complex mitral valve repairs, coronary revascularization, atrial fibrillation ablation, intracardiac tumor resections, atrial septal defect closures, and left ventricular lead implantation. The history and evolution of these procedures, as well as the present status and future directions of robotic cardiac surgery, are presented in this review. PMID:23908867

Dengue vector control: present status and future prospects.

PubMed

Yap, H H; Chong, N L; Foo, A E; Lee, C Y

1994-12-01

Dengue Fever (DF) and Dengue Haemorrhagic Fever (DHF) have been the most common urban diseases in Southeast Asia since the 1950s. More recently, the diseases have spread to Central and South America and are now considered as worldwide diseases. Both Aedes aegypti and Aedes albopictus are involved in the transmission of DF/DHF in Southeast Asian region. The paper discusses the present status and future prospects of Aedes control with reference to the Malaysian experience. Vector control approaches which include source reduction and environmental management, larviciding with the use of chemicals (synthetic insecticides and insect growth regulators and microbial insecticide), and adulticiding which include personal protection measures (household insecticide products and repellents) for long-term control and space spray (both thermal fogging and ultra low volume sprays) as short-term epidemic measures are discussed. The potential incorporation of IGRs and Bacillus thuringiensis-14 (Bti) as larvicides in addition to insecticides (temephos) is discussed. The advantages of using water-based spray over the oil-based (diesel) spray and the use of spray formulation which provide both larvicidal and adulticidal effects that would consequently have greater impact on the overall vector and disease control in DF/DHF are highlighted.

Teleoperated medical robotic systems allow procedures such as surgeries, treatments, and diagnoses to be conducted across short or long distances while utilizing wired and/or wireless communication networks. This study presents a systematic review of the relevant literature between the years 2004 and 2015, focusing on medical teleoperated robotic systems which have witnessed tremendous growth over the examined period. A thorough insight of telerobotics systems discussing design concepts, enabling technologies (namely robotic manipulation, telecommunications, and vision systems), and potential applications in clinical practice is provided, while existing limitations and future trends are also highlighted. A representative paradigm of the short-distance case is the da Vinci Surgical System which is described in order to highlight relevant issues. The long-distance telerobotics concept is exemplified through a case study on diagnostic ultrasound scanning. Moreover, the present review provides a classification into short- and long-distance telerobotic systems, depending on the distance from which they are operated. Telerobotic systems are further categorized with respect to their application field. For the reviewed systems are also examined their engineering characteristics and the employed robotics technology. The current status of the field, its significance, the potential, as well as the challenges that lie ahead are thoroughly discussed.

Telecommunications today are important factors in economic and social progress. The last decades of the 20th century and the early years of the 21st have been characterized as the Information Age. Telecommunications, the movement of information through distances, is absolutely critical to the economic and military survival of nations. This thesis is an attempt to predict the future of telecommunications, by studying and analyzing the past and present. First it examines the meaning of telecommunications today and some basics of information transmission. The current status of telecommunications is then presented, by examining the regional profiles as they are divided by the International Telecommunications Union. A number of statistical studies are given, which present a thorough picture of current world telecommunications. In an effort to predict future industry trends, the competition among the three largest telecommunications markets, U.S.A., Japan and the European Community, is also considered by looking at their present telecommunications industry, the efforts they make to improve their technology, and their plans for future investment. Finally, some major technological trends including BISDN, the use of fiber technology in the communications loop, and the use of solitons are examined. The new Metropolitan Area Network Protocol, FDDI-2 is also reviewed.

This research examined the function of future self-continuity and its potential downstream consequences for academic performance through relations with other temporal psychological factors and self-control. We also addressed the influence of cultural factors by testing whether these relations differed by college generation status. Undergraduate students enrolled at a large public university participated in two studies (Study 1: N = 119, M age  = 20.55, 56.4% women; Study 2: N = 403, M age  = 19.83, 58.3% women) in which they completed measures of temporal psychological factors and psychological resources. In Study 2, we also obtained academic records to link responses to academic performance. Future self-continuity predicted subsequent academic performance and was related positively to future focus, negatively to present focus, and positively to self-control. Additionally, the relation between future focus and self-control was stronger for continuing-generation college students than first-generation college students. Future self-continuity plays a pivotal role in academic contexts. Findings suggest that it may have positive downstream consequences on academic achievement by directing attention away from the present and toward the future, which promotes self-control. Further, the strategy of focusing on the future may be effective in promoting self-control only for certain cultural groups. © 2016 Wiley Periodicals, Inc.

Colletotrichum – current status and future directions

2012-01-01

A review is provided of the current state of understanding of Colletotrichum systematics, focusing on species-level data and the major clades. The taxonomic placement of the genus is discussed, and the evolution of our approach to species concepts and anamorph-teleomorph relationships is described. The application of multilocus technologies to phylogenetic analysis of Colletotrichum is reviewed, and selection of potential genes/loci for barcoding purposes is discussed. Host specificity and its relation to speciation and taxonomy is briefly addressed. A short review is presented of the current status of classification of the species clusters that are currently without comprehensive multilocus analyses, emphasising the orbiculare and destructivum aggregates. The future for Colletotrichum biology will be reliant on consensus classification and robust identification tools. In support of these goals, a Subcommission on Colletotrichum has been formed under the auspices of the International Commission on Taxonomy of Fungi, which will administer a carefully curated barcode database for sequence-based identification of species within the BioloMICS web environment.

Super-Resolving Toraldo Pupils for Radio Astronomical Applications: Current Status and Future Prospects

NASA Astrophysics Data System (ADS)

Olmi, Luca

2017-11-01

More than half a century ago, in 1952, Giuliano Toraldo di Francia suggested that the resolving power of an optical instrument could be improved using a filter consisting of finite-width concentric coronae of different amplitude and phase transmittance, now known as Toraldo Pupils (TPs). The concept of 'super- resolution' was born, and in the cur- rent literature it is generally associated with various meth- ods for improving the angular resolution of an optical imag- ing system beyond the classical diffraction limit. In the mi- crowave range, the first successful laboratory test of TPs was performed in 2003. These first results suggested that TPs could represent a viable approach to achieve super- resolution in Radio Astronomy. We have therefore started a project devoted to an exhaustive study of TPs and how they could be implemented on a radio telescope. In this work we present a summary of the status of this project, and then we will describe our future plans.

Current Status and Future Plan of Arctic Sea Ice monitoring in South Korea

NASA Astrophysics Data System (ADS)

Shin, J.; Park, J.

2016-12-01

Arctic sea ice is one of the most important parameters in climate. For monitoring of sea ice changes, the National Meteorological Satellite Center (NMSC) of Korea Metrological Administration has developed the "Arctic sea ice monitoring system" to retrieve the sea ice extent and surface roughness using microwave sensor data, and statistical prediction model for Arctic sea ice extent. This system has been implemented to the web site for real-time public service. The sea ice information can be retrieved using the spaceborne microwave sensor-Special Sensor Microwave Imager/Sounder (SSMI/S). The sea ice information like sea ice extent, sea ice surface roughness, and predictive sea ice extent are produced weekly base since 2007. We also publish the "Analysis report of the Arctic sea ice" twice a year. We are trying to add more sea ice information into this system. Details of current status and future plan of Arctic sea ice monitoring and the methodology of the sea ice information retrievals will be presented in the meeting.

Metal matrix composites: History, status, factors and future

NASA Astrophysics Data System (ADS)

Cyriac, Ajith James

The history, status, and future of metal matrix composites are presented by evaluating the progression of available literature through time. The trends that existed and issues that still prevail are discussed and a prediction of the future for MMCs is presented. The factors that govern the performance of metal matrix composites are also discussed. In many developed countries and in several developing countries there exists continued interest in MMCs. Researchers tried numerous combinations of matrices and reinforcements since work strictly on MMCs began in the 1950s. This led to developments for aerospace and defense applications, but resultant commercial applications were limited. The introduction of ceramic whiskers as reinforcement and the development of 'in-situ' eutectics in the 1960s aided high temperature applications in aircraft engines. In the late 1970s the automobile industries started to take MMCs seriously. In the last 20 years, MMCs evolved from laboratories to a class of materials with numerous applications and commercial markets. After the collapse of the Berlin Wall, prevailing order in the world changed drastically. This effect was evident in the progression of metal matrix composites. The internet connected the world like never before and tremendous information was available for researchers around the world. Globalization and the internet resulted in the transformation of the world to a more level playing field, and this effect is evident in the nature and source of research on metal matrix composites happening around the world.

Sumatran tiger (Panthera tigris sumatrae): a review of conservation status.

Wibisono, Hariyo T; Pusparini, Wulan

2010-12-01

The majority of wild Sumatran tigers are believed to live in 12 Tiger Conservation Landscapes covering approximately 88,000 km(2) . However, the actual distribution of tigers across Sumatra has never been accurately mapped. Over the past 20 years, conservation efforts focused on the Sumatran tigers have increased, but the population continues to decline as a result of several key threats. To identify the status of the Sumatran tiger distribution across the island, an island-wide questionnaire survey comprised of 35 respondents from various backgrounds was conducted between May and June 2010. The survey found that Sumatran tigers are positively present in 27 habitat patches larger than 250 km(2) and possibly present in another 2. In addition, a review on major published studies on the Sumatran tiger was conducted to identify the current conservation status of the Sumatran tiger. Collectively, these studies have identified several key factors that have contributed to the decline of Sumatran tiger populations, including: forest habitat fragmentation and loss, direct killing of tigers and their prey, and the retaliatory killing of tigers due to conflict with villagers. The present paper provides management authorities and the international community with a recent assessment and a base map of the actual distribution of Sumatran tigers as well as a general overview on the current status and possible future conservation challenges of Sumatran tiger management. © 2010 ISZS, Blackwell Publishing and IOZ/CAS.

2014-04-01

Education and training play vital role in the utilization of the technology. Shared and coordinated knowledge that geospatial technology and GIS deliver provides a deeper understanding of our present and will also help to better understand our future development. But it is not enough to explain new technological developments during congresses or workshops; it is also necessary to promote these new ideas and to distribute the knowledge by applying new learning strategies. This paper will review the status of computer aided teaching advances during the last decade, with a particular emphasis on photogrammetry, remote sensing, and geomatics. Some best practise examples will be presented featuring prominently recent Massive Open Online Courses (MOOCs) related to our fields. The consideration of mainly free online learning resources will include a commentary on quality and perceived effectiveness.

The Subjective Health Horizon Questionnaire (SHH-Q): Assessing Future Time Perspectives for Facets of an Active Lifestyle.

A wider subjective time horizon is assumed to be positively associated with longevity and vitality. In particular, a lifestyle with exposure to novel and varied information is considered beneficial for healthy cognitive aging. At present, measures that specifically assess individuals' perceived temporal extension to engage in active lifestyles in the future are not available. We introduce and validate a new self-report measure, the Subjective Health Horizon Questionnaire (SHH-Q). The SHH-Q assesses individuals' future time perspectives in relation to four interrelated but distinct lifestyle dimensions: (1) novelty-oriented exploration (Novelty), (2) bodily fitness (Body), (3) work goals (Work), and (4) goals in life (Life Goals). The present study aims at: (a) validating the hypothesized factor structure of the SHH-Q, according to which the SHH-Q consists of four interrelated but distinct subscales, and (b) testing the hypothesis that the Novelty and Body subscales of the SHH-Q show positive and selective associations with markers of cognition and somatic health, respectively. Using structural equation modeling, we analyzed data from 1,371 healthy individuals (51% women) with a mean age of 70.1 years (SD = 3.6) who participated in the Berlin Aging Study II (BASE-II) and completed the SHH-Q. As predicted, the SHH-Q formed four correlated but distinct subscales: (1) Novelty, (2) Body, (3) Work, and (4) Life Goals. Greater self-reported future novelty orientation was associated with higher current memory performance, and greater future expectations regarding bodily fitness with better current metabolic status. The SHH-Q reliably assesses individual differences in four distinct dimensions of future time perspective. Two of these dimensions, Novelty and Body, show differential associations with cognitive status and somatic health. The SHH-Q may serve as a tool to assess how different facets of future time perspective relate to somatic health, cognition, motivation, and affect, and may help to identify the socioeconomic and individual antecedents, correlates, and consequences of an active lifestyle. © 2016 S.

Territory inheritance in clownfish.

PubMed Central

Buston, Peter M

2004-01-01

Animal societies composed of breeders and non-breeders present a challenge to evolutionary theory because it is not immediately apparent how natural selection can preserve the genes that underlie non-breeding strategies. The clownfish Amphiprion percula forms groups composed of a breeding pair and 0-4 non-breeders. Non-breeders gain neither present direct, nor present indirect benefits from the association. To determine whether non-breeders obtain future direct benefits, I investigated the pattern of territory inheritance. I show that non-breeders stand to inherit the territory within which they reside. Moreover, they form a perfect queue for breeding positions; a queue from which nobody disperses and within which nobody contests. I suggest that queuing might be favoured by selection because it confers a higher probability of attaining breeding status than either dispersing or contesting. This study illustrates that, within animal societies, individuals may tolerate non-breeding positions solely because of their potential to realize benefits in the future. PMID:15252999

Leger, Kate A.; Charles, Susan T.; Ayanian, John Z.; Almeida, David M.

2015-01-01

Rationale Daily physical symptoms play a critical role in health and illness experiences. Despite their daily prevalence, the ability of these symptoms to predict future health status is debated. Objective The current study examined whether physical symptom reports predict future health outcomes independent of trait measures of emotion. Methods Participants (N = 1189) who completed both Midlife in the United States (MIDUS) Surveys I and II as well as the National Study of Daily Experiences (NSDE) reported their daily physical symptoms at baseline and number of reported chronic conditions and functional disability nearly 10 years later. Results Physical symptoms at baseline significantly predicted the occurrence of chronic conditions and functional impairment at long-term follow-up, even after adjusting for self-reported affect, self-reported health, and previous health status. Conclusion Findings suggest that daily physical symptoms are unique indicators of future health status. PMID:26364011

Lasseur, Christophe; Paille, Christel

2016-07-01

Since 1987, the European Space Agency has been active in the field of Life Support development. When compare to its international colleagues, it is clear that ESA started activities in the field with a "delay of around 25 years. Due to this situation and to avoid duplication, ESA decided to focus more on long term manned missions and to consider more intensively regenerative technologies as well as the associated risks management ( e.g. physical, chemical and contaminants). Fortunately or not, during the same period, no clear plan of exploration and consequently not specific requirements materialized. This force ESA to keep a broader and generic approach of all technologies. Today with this important catalogue of technologies and know-how, ESA is contemplating the different scenario of manned exploration beyond LEO. In this presentation we review the key scenario of future exploration, and identify the key technologies who loo the more relevant. An more detailed status is presented on the key technologies and their development plan for the future.

A Perspective on the Use of Storable Propellants for Future Space Vehicle Propulsion

NASA Technical Reports Server (NTRS)

Boyd, William C.; Brasher, Warren L.

1989-01-01

Propulsion system configurations for future NASA and DOD space initiatives are driven by the continually emerging new mission requirements. These initiatives cover an extremely wide range of mission scenarios, from unmanned planetary programs, to manned lunar and planetary programs, to earth-oriented (Mission to Planet Earth) programs, and they are in addition to existing and future requirements for near-earth missions such as to geosynchronous earth orbit (GEO). Increasing space transportation costs, and anticipated high costs associated with space-basing of future vehicles, necessitate consideration of cost-effective and easily maintainable configurations which maximize the use of existing technologies and assets, and use budgetary resources effectively. System design considerations associated with the use of storable propellants to fill these needs are presented. Comparisons in areas such as complexity, performance, flexibility, maintainability, and technology status are made for earth and space storable propellants, including nitrogen tetroxide/monomethylhydrazine and LOX/monomethylhydrazine.

2017-10-01

To examine the rationale and applications of amniotic tissue augmentation in urological surgery. Published literature in English-language was reviewed for basic science and clinical use of amniotic or amnion-chorionic tissue in genitourinary tissues. Basic science and animal studies support the likely benefit of clinical applications of amnion-derived tissues in a variety of urologic interventions. The broad number of properties found in amniotic membrane, coupled with its immunologically privileged status presents a number of future applications in the urological surgical realm. These applications are in their clinical infancy and suggest that further studies are warranted to investigate the use of these products in a systematic fashion.

Japanese public long-term care insured: preferences for future long-term care facilities, including relocation, waiting times, and individualized care.

Sawamura, Kanae; Sano, Hiroshi; Nakanishi, Miharu

2015-04-01

Expenditures on long-term care insurance (LTCI) in Japan have been increasing with the aging of the population, which has led to an increase in premiums. To optimize resource allocation, we aim to clarify the priorities of the functions of long-term care facilities from the viewpoint of future beneficiaries. The present study was conducted using a cross-sectional study design. We conducted a mail-in survey targeting 2400 adults aged 50-65 in 8 cities in Japan, and 371 persons responded. Conjoint analysis was applied to measure participants' preferences for long-term care facility services. Participants read 1 of 2 vignettes of an 80-year-old person with either dementia or a fracture, and were asked to envision it as a possible future scenario for themselves. Participants then completed 8 or 9 tasks to select suitable long-term care facilities for the person described. The questionnaire also contained common questions on participants' personal profiles: age, gender, family situation, education, approximate yearly family income, experience as a family caregiver, dwelling status, present health status, and possibility of requiring long-term care services in the future. The results focused mainly on (1) possibilities of individual choice for daily schedules/meals; (2) availability of regular care staff; (3) room; (4) main daily interactions; (5) necessity of relocation associated with medical deterioration; 6) Waiting time; 7) distance from present residence; and (8) monthly fees. Necessity of relocation associated with medical deterioration was consistently given the greatest importance. Participants with experience as a family caregiver showed significantly greater preference for individualized care and communication. The option of avoiding relocation was highly valued by participants compared with private rooms and individualized care. The present situation of high demand for intensive care homes for the elderly, provoked by anxiety about future residence, will not change unless a robust system is built to support residents even when their health has deteriorated. Individualized care has been promoted by long-term care insurance policies, but further advances will require efforts to obtain the understanding of the insured.

Yang, Dong Hyun; Kim, Young-Hak

2017-07-01

Computed tomography myocardial perfusion (CTP) combined with coronary computed tomography angiography (CCTA) may constitute a "1-stop shop" for the noninvasive diagnosis of hemodynamically significant coronary stenosis during a single CT examination. CTP shows high diagnostic performance and provides incremental value over CCTA for the detection of hemodynamically significant coronary stenosis in patients with a high Agatston calcium score or coronary artery stents. Future studies should determine the optimal protocol and clinical value of CTP for guiding revascularization strategy and prognostication. In this article, we review the current status and future perspectives of CTP, focusing on technical considerations, clinical applications, and future research topics.

Ennis, William J; Valdes, Wesley; Meneses, Patricio

2004-01-01

This article represents a process paper describing the development, at our facility, of a wound care fellowship that was scheduled to begin in July of 2003. The proposed program is in no way a finished product or our statement of how the program must be. This article is presented as a call to wound care professionals for input, criticism, guidance, and--we hope--adoption and acceptance of wound care fellowships in some format in the future. After many years of work in this field, it has become apparent that without medical specialization wound care will never rise from its current status of part-time avocation to full-time occupation. After a brief background and description of the present status of wound care education, an initial curriculum, program objectives, and clinical rotation schedule are presented. We look forward to the day when this program will have been replaced with a fully accredited, readily accepted, board-certifiable fellowship program with all the rights and responsibilities afforded the other medical specialties.

The effects of state terrorism and exile on indigenous Guatemalan refugee children: a mental health assessment and an analysis of children's narratives.

Miller, K E

1996-02-01

This study examined the mental health and psychosocial development of 58 Guatemalan Mayan Indian children living in 2 refugee camps in the Mexican state of Chiapas. Conventional assessment instruments were adapted for use in this unique context, and semistructured interviews were utilized to gather phenomenological data from children regarding various developmental, sociocultural, and political topics. Data are presented that show minimal evidence of psychological trauma in this sample, and various factors are suggested to account for this finding. In addition, data are presented showing a positive relationship between children's mental health and the health status (physical and mental) of their mothers. In particular, a strong association was found between depressive symptomatology in girls and poor health status in their mothers. Qualitative data from the interviews are presented, focusing on children's understandings of why their families fled Guatemala, the nature and causes of the violence, and their thoughts and feelings regarding the prospect of returning to Guatemala at some future point.

2016-01-01

White Sturgeon, Acipenser transmontanus (WS), are distributed throughout three major river basins on the West Coast of North America: the Sacramento-San Joaquin, Columbia, and Fraser River drainages. Considered the largest North American freshwater fish, some WS use estuarine habitat and make limited marine movements between river basins. Some populations are listed by the United States or Canada as threatened or endangered (upper Columbia River above Grand Coulee Dam; Kootenai River; lower, middle and, upper Fraser River and Nechako River), while others do not warrant federal listing at this time (Sacramento-San Joaquin Rivers; Columbia River below Grand Coulee Dam; Snake River). Threats that impact WS throughout the species’ range include fishing effects and habitat alteration and degradation. Several populations suffer from recruitment limitations or collapse due to high early life mortality associated with these threats. Efforts to preserve WS populations include annual monitoring, harvest restrictions, habitat restoration, and conservation aquaculture. This paper provides a review of current knowledge on WS life history, ecology, physiology, behavior, and genetics and presents the status of WS in each drainage. Ongoing management and conservation efforts and additional research needs are identified to address present and future risks to the species.

Two of the main issues in artificial intelligence today are knowledge acquisition dion and knowledge representation. The Dryden Flight Research Facility of NASA's Ames Research Center is presently involved in the design and implementation of an expert system flight status monitor that will provide expertise and knowledge to aid the flight systems engineer in monitoring today's advanced high-performance aircraft. The flight status monitor can be divided into two sections: the expert system itself and the knowledge acquisition tool. The knowledge acquisition tool, the means it uses to extract knowledge from the domain expert, and how that knowledge is represented for computer use is discussed. An actual aircraft system has been codified by this tool with great success. Future real-time use of the expert system has been facilitated by using the knowledge acquisition tool to easily generate a logically consistent and complete knowledge base.

Participants [n = 161, mean age (range) = 74 (65-96) years] completed interviewer-administered questionnaires and objective measures of mobility. Our findings did not generally indicate that older adults of low socioeconomic status have a reduced capacity to be mobile. Participants presented with positive profiles across physical, psychosocial, and social environment domains that influence the capacity to be mobile. They also made a high proportion of trips by foot, although these did not together serve to meet physical activity guidelines for most. We challenge future researchers to focus on innovative strategies to recruit this difficult-to-access population, to consider the influence of socioeconomic status across the lifespan, and the role of behaviour-driven agency when investigating the association between the person, environment, and older adult mobility.

Researchers have little explored individuals' perceptions of same-sex attractiveness in terms of the influence of relationship status. By using intrasexual competition as a conceptual framework, the authors predicted that romantically involved individuals would protect their relationship by derogating competitors. Although previous researchers have strongly predicted this result, in the present study the relationship status had a negligible impact on competition, for which relationship commitment, sociosexual orientation, and self-monitoring did not account. Also, among uninvolved individuals, the authors expected those individuals seeking mates would use competitor derogation more than would those individuals not seeking mates, but there was no significant difference. Finally, because the vehicle for this investigation was attractiveness, an area in which women compete, the authors proposed that women would derogate more fiercely than would men. However, the results did not support this hypothesis either. The authors discuss future directions for research.

Past research suggests robust positive associations between household socioeconomic status and children's early cognitive development in Western countries. Relatively little is known about these relations in low-income country settings characterized by economic adversity, high prevalence of malnutrition and infectious disease, and relatively lower school enrollment. The present study develops and empirically evaluates an adapted model of early childhood development using a sample of 2,711 Zambian 6-year-olds. Early learning in and out of the home was found to explain much of the relation between socioeconomic status and children's cognitive skills, including language, nonverbal reasoning, and executive function. Child height-for-age (a proxy for overall nutritional status and health) was also predictive of children's cognitive skills and both early and on-time school enrollment. Implications for global child development, intervention, and future work are discussed. (c) 2015 APA, all rights reserved).

The diabetic foot ulcer (DFU) is an invariably common complication of diabetes mellitus, it is also a significant cause of amputation as well as extended hospitalization. As most patients with DFU suffer from malnutrition, which has been related to improper metabolic micronutrients status, alterations can affect impaired wound healing process. Micronutrients and herbal remedies applications present a wide range of health advantages to patients with DFU. The purpose of this review is to provide current evidence on the potential effect of dietary supplementations such as vitamins A, C, D, E, magnesium, zinc, copper, iron, boron, and such naturally occurring compounds as Aloe vera, Naringin, and Radix Astragali (RA) and Radix Rehmanniae (RR) in the administration of lower extremity wounds, especially in DFU, and to present some insights for applications in the treatment of DFU patients in the future.

The Far-Infrared Surveyor (FIS) is one of the on-board instruments on the ASTRO-F satellite, which will be launched in early 2004. The first a half year of its mission period of 500 days is dedicated to an all sky survey in four bands between 50 and 200 micron. On the basis of the present hardware specifications and configurations of the FIS, we have written a computer program to simulate the FIS. The program can be used to evaluate the performance of the instrument as well as to produce input for the data reduction system. In this paper, we describe the current status of the program. As an example of the usage of the simulation program, we present the expected observing data for three different detector sampling rates. The functions which should be implemented into the program, in the future, are enumerated.

Pangolins are unique placental mammals with eight species existing in the world, which have adapted to a highly specialized diet of ants and termites, and are of significance in the control of forest termite disaster. Besides their ecological value, pangolins are extremely important economic animals with the value as medicine and food. At present, illegal hunting and habitat destruction have drastically decreased the wild population of pangolins, pushing them to the edge of extinction. Captive breeding is an important way to protect these species, but because of pangolin's specialized behaviors and high dependence on natural ecosystem, there still exist many technical barriers to successful captive breeding programs. In this paper, based on the literatures and our practical experience, we reviewed the status and existing problems in captive breeding of pangolins, including four aspects, the naturalistic habitat, dietary husbandry, reproduction and disease control. Some recommendations are presented for effective captive breeding and protection of pangolins.

Concepts for Multi-Speed Rotorcraft Drive System - Status of Design and Testing at NASA GRC

Stevens, Mark A.; Lewicki, David G.; Handschuh, Robert F.

2015-01-01

In several studies and on-going developments for advanced rotorcraft, the need for variable multi-speed capable rotors has been raised. Speed changes of up to 50 have been proposed for future rotorcraft to improve vehicle performance. A rotor speed change during operation not only requires a rotor that can perform effectively over the operating speedload range, but also requires a propulsion system possessing these same capabilities. A study was completed investigating possible drive system arrangements that can accommodate up to a 50 speed change. Key drivers were identified from which simplicity and weight were judged as central. This paper presents the current status of two gear train concepts coupled with the first of two clutch types developed and tested thus far with focus on design lessons learned and areas requiring development. Also, a third concept is presented, a dual input planetary differential as leveraged from a simple planetary with fixed carrier.

Bioaccumulation and toxicodynamics of cadmium to freshwater planarian and the protective effect of N-acetylcysteine.

Wu, Jui-Pin; Chen, Hon-Cheng; Li, Mei-Hui

2012-08-01

Although toxic responses of freshwater planarians after exposure to environmental toxicants can be observed through external toxicological end points, physiological responses inside the bodies of treated planarians have rarely been investigated. The present study was designed, using cadmium (Cd) as a reference toxicant, to determine its bioaccumulation and toxicodynamics in the freshwater planarian, Dugesia japonica, after acute toxicity was obtained. Accumulated Cd concentrations, metallothionein levels, and the oxidative status in planarians were determined after exposure to Cd. Furthermore, we hypothesized that the acute death of Cd-treated planarians was associated with increased oxidative stress. After Cd-treated planarians were coexposed to antioxidant, N-acetylcysteine (NAC), we found that NAC protected planarians from Cd lethality by maintaining the oxidative status and decreasing the bioaccumulation of Cd. The results of the present study support planarians being used as a practical model for toxicological studies of environmental contaminants in the future.

Since July 2015, Sentinel-2A provides high-quality multi-spectral images with 10 m spatial resolution. With the launch of Sentinel-2B scheduled for early March 2017, the mission will create a consistent time series with a revisit time of 5 days. The consistency of the time series is ensured by some specific performance requirements such as multi-temporal spatial co-registration and radiometric stability, routinely monitored by the Sentinel-2 Mission Performance Centre (S2MPC). The products also provide a rich set of metadata and auxiliary data to support higher-level processing. This presentation will focus on the current status of the Sentinel-2 L1C and L2A products, including dissemination and product format aspects. Up-to-date mission performance estimations will be presented. Finally we will provide an outlook on the future evolutions: commissioning tasks for Sentinel-2B, geometric refinement, product format and processing improvements.

Consideration of immediate and future consequences, smoking status, and body mass index.

Adams, Jean

2012-03-01

Health-related behaviors often involve immediate costs to achieve long-term benefits. How one considers the future outcomes of present day behaviors (e.g., temporal orientation) may play a role in engagement in healthy behaviors. The Consideration of Future Consequences Scale (CFCS) measures temporal orientation on a unidimensional continuum. Recently, 2 subscales of the CFCS have been reported: immediate (CFC-I) and future (CFC-F) consequences. These support a multidimensional conceptualization of temporal orientation. Confirmatory factor analysis was performed on CFCS data. The associations between 2 health-related variables [smoking and body mass index (BMI)] and each subscale were then explored, controlling for sociodemographic variables. A random sample of 2,000 individuals aged 18 years or over was selected from the edited electoral role for one English city and sent a postal questionnaire, including the CFCS and questions on age, gender, socioeconomic position, and self-reported current smoking status and BMI. Complete data was provided by 800 participants (response rate = 40.0%). The 2-factor model fitted CFCS data better than the 1-factor model. In multiple linear regression, CFC-I was positively associated with BMI, B (95% confidence interval [CI]) = 0.47 (0.06 to 0.88), p = .025; and odds of being a current smoker, odds ratio (95% CI) = 1.28 (1.02 to 1.60), p = .035; CFC-F was not associated with health-related variables. These data support the multidimensional conceptualization of temporal orientation. Consideration of immediate consequences may be a more important determinant of health-related behaviors than consideration of future consequences.

A total of 88 people-70 sixth-year undergraduate students from 70 universities, and 18 alumni who had participated in the First and the Second Workshops-attended this Workshop. The theme of this Workshop was "Contribution to medical care and society: How will I act as a pharmacist in the future?" The first day took the form of a World Café, with participants exchanging information on such topics as, "The purpose for choosing a pharmacy major, and my achievement status", "My favorite aspects of my college", and "My dreams and paths: Painting my future image". Later that day, participants discussed and gave presentations on the ways they would be contributing as pharmacists to society and medical care. On the second day, participants discussed and gave presentations on the efforts they would like to make as pharmacists to contribute to society and medical care. The final session was a general assembly for discussion on the ways they would be contributing as pharmacists to society and medical care. Throughout the two days, attendees participated in discussions with an awareness of their common ground, in that they all had national qualification in spite of different intended paths. In this article, 4 sixth-year students (their status at the time of the symposium) from the Workshop introduce outlines of the discussions and products from each group.

The Grid as a healthcare provision tool.

Hernández, V; Blanquer, I

2005-01-01

This paper presents a survey on HealthGrid technologies, describing the current status of Grid and eHealth and analyzing them in the medium-term future. The objective is to analyze the key points, barriers and driving forces for the take-up of HealthGrids. The article considers the procedures from other Grid disciplines such as high energy physics or biomolecular engineering and discusses the differences with respect to healthcare. It analyzes the status of the basic technology, the needs of the eHealth environment and the successes of current projects in health and other relevant disciplines. Information and communication technology (ICT) in healthcare is a promising area for the use of the Grid. There are many driving forces that are fostering the application of the secure, pervasive, ubiquitous and transparent access to information and computing resources that Grid technologies can provide. However, there are many barriers that must be solved. Many technical problems that arise in eHealth (standardization of data, federation of databases, content-based knowledge extraction, and management of personal data ...) can be solved with Grid technologies. The article presents the development of successful and demonstrative applications as the key for the take-up of HealthGrids, where short-term future medical applications will surely be biocomputing-oriented, and the future of Grid technologies on medical imaging seems promising. Finally, exploitation of HealthGrid is analyzed considering the curve of the adoption of ICT solutions and the definition of business models, which are far more complex than in other e-business technologies such ASP.

Palliative care, which is a special type of care including alleviation of physical and psychosocial symptoms of individuals with life-limiting serious diseases, has long been neglected in Turkey. This has also affected the activity of social work and social workers in the presentation of health services. In the present study, the present status of social work in palliative care services in Turkey was analyzed. It has also been attempted to explain the historical place of social work in palliative care services from 2002 on under the guidance of the World Health Organization and Ministry of Health. In the present study, an analysis is carried out of stages social work profession went through in social care services, its strong and weak aspects, and its future perspectives. It is thought that the experience gained and accumulation of knowledge in this process as it has occurred in Turkey may serve as guidance for other countries that have only recently started to implement palliative care services, which are evaluated in the context of human rights at present.

Excess nutrient inputs and climate change are two of multiple stressors affecting many lakes worldwide. Lake Vansjø in southern Norway is one such eutrophic lake impacted by blooms of toxic blue-green algae (cyanobacteria), and classified as moderate ecological status under the EU Water Framework Directive. Future climate change may exacerbate the situation. Here we use a set of chained models (global climate model, hydrological model, catchment phosphorus (P) model, lake model, Bayesian Network) to assess the possible future ecological status of the lake, given the set of climate scenarios and storylines common to the EU project MARS (Managing Aquatic Ecosystems and Water Resources under Multiple Stress). The model simulations indicate that climate change alone will increase precipitation and runoff, and give higher P fluxes to the lake, but cause little increase in phytoplankton biomass or changes in ecological status. For the storylines of future management and land-use, however, the model results indicate that both the phytoplankton biomass and the lake ecological status can be positively or negatively affected. Our results also show the value in predicting a biological indicator of lake ecological status, in this case, cyanobacteria biomass with a BN model. For all scenarios, cyanobacteria contribute to worsening the status assessed by phytoplankton, compared to using chlorophyll-a alone. Copyright © 2017 The Authors. Published by Elsevier B.V.

In vivo microrobots for natural orifice transluminal surgery. Current status and future perspectives.

Forgione, A

2009-06-01

The possibility to operate inside the peritoneal cavity through small holes performed in hollow organs that is presented by Natural Orifice Transluminal Endoscopic Surgery (NOTES) represents a major paradigm shift in general surgery. While this new approach seems very appealing from patients' perspectives because it eliminates completely abdominal wall aggression and promises to reduce postoperative pain, it is very challenging for surgeons because of the major constraints imposed by both the mode of access and the limited technology currently available. For this reason NOTES applications at the present time are performed by only a few surgeons and mainly to perform non-complex procedures. While new devices are under development, many of them are trying mainly to simply improve current endoscopic platforms and seem not to offer breakthrough solutions. The numerous challenges introduced by natural orifice approaches require a radical shift in the conception of new technologies in order to make this emerging operative access safe and reproducible. The convergence of several enabling technologies in the field of miniaturization, communication and micro-mechatronics brings the possibility to realize on a large scale the revolutionary concept of miniature in vivo co-operative robots. These robots provide vision and task assistance without the constraints of the entry incision and have been shown in experimental settings to possess many qualities that could be ideal to partner with Natural Orifice Surgery. This article explores the current status of microrobotics as well as presents potential future scenarios of their applications in NOTES.

The proliferation of four-dimensional imaging technologies, increasing computational speeds, improved simulation algorithms, and the widespread availability of powerful computing platforms is enabling simulations of cardiac hemodynamics with unprecedented speed and fidelity. Since cardiovascular disease is intimately linked to cardiovascular hemodynamics, accurate assessment of the patient's hemodynamic state is critical for the diagnosis and treatment of heart disease. Unfortunately, while a variety of invasive and non-invasive approaches for measuring cardiac hemodynamics are in widespread use, they still only provide an incomplete picture of the hemodynamic state of a patient. In this context, computational modeling of cardiac hemodynamics presents as a powerful non-invasive modality that can fill this information gap, and significantly impact the diagnosis as well as the treatment of cardiac disease. This article reviews the current status of this field as well as the emerging trends and challenges in cardiovascular health, computing, modeling and simulation and that are expected to play a key role in its future development. Some recent advances in modeling and simulations of cardiac flow are described by using examples from our own work as well as the research of other groups.

An overview is presented of the NASA Lewis Research Center Free-Piston Stirling Space Power Converter Technology Development Program. This work is being conducted under NASA's Civil Space Technology Initiative (CSTI). The goal of the CSTI High Capacity Power element is to develop the technology base needed to meet the long duration, high capacity power requirements for future NASA space initiatives. Efforts are focused upon increasing system thermal and electric energy conversion efficiency at least fivefold over current SP-100 technology, and on achieving systems that are compatible with space nuclear reactors. The status of test activities with the Space Power Research Engine (SPRE) is discussed. Design deficiencies are gradually being corrected and the power converter is now outputting 11.5 kWe at a temperature ratio of 2 (design output is 12.5 kWe). Detail designs were completed for the 1050 K Component Test Power Converter (CTPC). The success of these and future designs is dependent upon supporting research and technology efforts including heat pipes, gas bearings, superalloy joining technologies and high efficiency alternators. An update of progress in these technologies is provided.

Is the Belief in Meritocracy Palliative for Members of Low Status Groups? Evidence for a Benefit for Self-Esteem and Physical Health via Perceived Control

2013-01-01

Consensually held ideologies may serve as the cultural “glue” that justifies hierarchical status differences in society (e.g. Augustinos, 1998). Yet to be effective these beliefs need to be embraced by low-status groups. Why would members of low-status groups endorse beliefs that justify their relative disadvantage? We propose that members of low-status groups in the United States may benefit from some system-justifying beliefs (such as the belief in meritocracy) to the extent that these beliefs emphasize the perception of control over future outcomes. In 2 studies, among women, lower-SES women, and women of color, we found a positive relationship between the belief in meritocracy and well-being (self-esteem and physical health) that was mediated by perceived control. Members of low-status groups may benefit from some system-justifying beliefs to the extent that these beliefs, like the belief in meritocracy, emphasize the perception of control over future outcomes.

To assess the present status of the clinical laboratory database management system, the difference between the Clinical Laboratory Information System and Clinical Laboratory System was explained in this study. Although three kinds of database management systems (DBMS) were shown including the relational model, tree model and network model, the relational model was found to be the best DBMS for the clinical laboratory database based on our experience and developments of some clinical laboratory expert systems. As a future clinical laboratory database management system, the IC card system connected to an automatic chemical analyzer was proposed for personal health data management and a microscope/video system was proposed for dynamic data management of leukocytes or bacteria.

Radiotherapy is along with surgery and chemotherapy one of the prime treatment modalities in cancer. It is applied in the primary, neoadjuvant as well as the adjuvant setting. Radiation techniques have rapidly evolved during the past decade enabling the delivery of high radiation doses, reducing side-effects in tumour-adjacent normal tissues. While increasing local tumour control, current and future efforts ought to deal with microscopic disease at a distance of the primary tumour, ultimately responsible for disease-progression. This review explores the possibility of bimodal treatment combining radiotherapy with immunotherapy. Copyright © 2014 Société française de radiothérapie oncologique (SFRO). Published by Elsevier SAS.

Jaffe, L. D.

1981-01-01

Comparisons are presented of point-focusing, or 'dish' solar concentrator system features, development status, and performance levels demonstrated to date. In addition to the requirements of good optical efficiency and high geometric concentration ratios, the most important future consideration in solar thermal energy dish concentrator design will be the reduction of installed and lifetime costs, as well as the materials and labor costs of production. It is determined that technology development initiatives are needed in such areas as optical materials, design wind speeds and wind loads, structural configuration and materials resistance to prolonged exposure, and the maintenance of optical surfaces. The testing of complete concentrator systems, with energy-converting receivers and controls, is also necessary. Both reflector and Fresnel lens concentrator systems are considered.

To investigate the working patterns and patient base of registered clinical dental technicians (CDTs); their relationships with dentists and other professionals in the dental team; their willingness to work within the NHS and their expectations for the future as a new professional group. Face-to-face qualitative interviews of registered CDTs, selected because of their geographic representation and mode of working, informed the development of a postal questionnaire survey of all early registrants with the General Dental Council (GDC). The majority of CDTs reported working part-time, often combining clinical practice with their role as a dental technician. They reported both positive and negative working relationships with dentists and dental technicians, demonstrating collaboration and/or competition depending on whether the scope of CDTs was respected and patient care was shared or lost. CDTs role in the NHS was limited because they did not have the status of becoming a recognised provider of dental care. There was a desire to expand their scope of practice in future. CDTs are embracing their new status as an occupational group within dentistry. Core features of becoming a professional group were exhibited including the importance of social and financial status and the need to negotiate their current and future roles in the healthcare system.

2016-03-15

Margaritifera marocana is one of the rarest freshwater mussel species (listed as critically endangered), and is endemic to Morocco. Despite its constrained distribution and low abundance, to date there are no quantitative studies addressing the conservation status of this species. Surveys were conducted in 36 sites along the Oum Er Rbia river basin (Rivers Derna, Laabid and Oum Er Rbia) to assess the distribution, abundance, population structure and genetic diversity of M. marocana. Just one specimen was found on River Oum Er Rbia and none on River Derna; however, a high abundance was found in the lower section of River Laabid (e.g., site Laabid 6 reached a mean density of 11.0 ± 6.8 ind.m(-2)). Contrary to earlier information, which reported an overall population size fewer than 250 individuals in a restricted area and no juvenile presence, this study showed that a much higher abundance exists in River Laabid alone. In addition, the species is present in more than 50 km of this river and is still recruiting since small specimens were found. Regarding genetic diversity, six of nine loci previously used in Margaritifera margaritifera were polymorphic and suitable in M. marocana. The spatial range contraction of this species is likely to be very recent, since no strong signature was detected by the molecular diversity indices. Information gathered in this study can be used as a reference to the present conservation status of M. marocana, and guide future research and management initiatives to better conserve it. We conclude discussing the potential major threats for the future survival of M. marocana and suggest some management measures (and research needs) that should be urgently applied.

A better understanding of the natural history of osteogenesis imperfecta (OI) in adulthood should improve health care for patients with this rare condition. The Osteogenesis Imperfecta Foundation established the Adult Natural History Initiative (ANHI) in 2010 to give voice to the health concerns of the adult OI community and to begin to address existing knowledge gaps for this condition. Using a web-based platform, 959 adults with self-reported OI, representing a wide range of self-reported disease severity, reported symptoms and health conditions, estimated the impact of these concerns on present and future health-related quality of life (QoL) and completed a Patient-Reported Outcomes Measurement Information System (PROMIS®) survey of health issues. Adults with OI report lower general physical health status (p < .0001), exhibit a higher prevalence of auditory (58% of sample versus 2-16% of normalized population) and musculoskeletal (64% of sample versus 1-3% of normalized population) concerns than the general population, but report generally similar mental health status. Musculoskeletal, auditory, pulmonary, endocrine, and gastrointestinal issues are particular future health-related QoL concerns for these adults. Numerous other statistically significant differences exist among adults with OI as well as between adults with OI and the referent PROMIS® population, but the clinical significance of these differences is uncertain. Adults with OI report lower general health status but are otherwise more similar to the general population than might have been expected. While reassuring, further analysis of the extensive OI-ANHI databank should help identify areas of unique clinical concern and for future research. The OI-ANHI survey experience supports an internet-based strategy for successful patient-centered outcomes research in rare disease populations.

Previous studies suggest that task-activated functional magnetic resonance imaging (fMRI) can predict future cognitive decline among healthy older adults. The present fMRI study examined the relative sensitivity of semantic memory (SM) versus episodic memory (EM) activation tasks for predicting cognitive decline. Seventy-eight cognitively intact elders underwent neuropsychological testing at entry and after an 18-month interval, with participants classified as cognitively "Stable" or "Declining" based on ≥ 1.0 SD decline in performance. Baseline fMRI scanning involved SM (famous name discrimination) and EM (name recognition) tasks. SM and EM fMRI activation, along with Apolipoprotein E (APOE) ε4 status, served as predictors of cognitive outcome using a logistic regression analysis. Twenty-seven (34.6%) participants were classified as Declining and 51 (65.4%) as Stable. APOE ε4 status alone significantly predicted cognitive decline (R(2) = .106; C index = .642). Addition of SM activation significantly improved prediction accuracy (R(2) = .285; C index = .787), whereas the addition of EM did not (R(2) = .212; C index = .711). In combination with APOE status, SM task activation predicts future cognitive decline better than EM activation. These results have implications for use of fMRI in prevention clinical trials involving the identification of persons at-risk for age-associated memory loss and Alzheimer's disease.

Geothermal Energy uses the natural heat of the Earth. It is a local energy source, competitive, renewable and acceptable from the ecological and social points of view, which is used either for the electricity production, or for direct application such as a district heating. A great number of operating geothermal installations are found in Europe. European Community energy programs foresee in the coming years a great reduction of conventional fuel consumption, due to the risks that dependency on imported fuels implies and to the future environmental problems, which a mass exploitation of these fuels can lead to. Thus, EC energymore » policy is aimed at a drastic reduction of oil consumption and at diversification of primary energy sources.

1991-01-01

While it sounded great to be asked to talk about composites, I found it difficult to select subject areas that would be of real interest. My choice is based on saying some things about where the maturity of the composite aircraft structures is today and what that means in terms of future criteria for application. This focus was the basis for my title selection. The other issue that will be addressed was requested by NASA and focuses on composites structures cost. This fits well with the state-of-the-art interpretations I will discuss first, since the cost issue must be viewed from both the current status and future points of view. The difficulty in presenting something in these areas is not in the subjects themselves but in trying to present a real world viewpoint to an audience of composite experts. So, with recognition of the expertise of the audience, I hope you will see something in this presentation about how to view composite aircraft structure.

Impact of Relationship Status and Quality (Family Type) on the Mental Health of Mothers and Their Children: A 10-Year Longitudinal Study.

PubMed

Hannighofer, Jasmin; Foran, Heather; Hahlweg, Kurt; Zimmermann, Tanja

2017-01-01

Mothers and children of single or unstable relationships have higher rates of mental health problems than those in stable two-parent families. Despite results that mothers and children of conflictual two-parent families also show impairments, most studies do not consider relationship quality. Therefore, the present study combines relationship status and relationship quality to a "family type." The present study compares German mothers and children of two-parent families with high relationship quality to those from two-parent families with a low quality, single mothers, and unstable families. Data of n  = 249 families from a 10-year follow-up longitudinal study show that mothers with a high relationship quality show the highest levels of mental health whereas all other groups show at least a 3.2 times higher probability of mental health symptoms. Children of mothers in unstable relationships show a 8.2 times higher probability to emotional or behavioral problems than children of mothers with high relationship quality. Therefore, not only relationship status but also relationship quality should be combined and this "family type" should be considered in future research.

2006-09-01

The health issues of young adulthood have received relatively little attention compared with those of adolescence, although the critical issues in young adulthood parallel those of adolescence. Young adults often fare worse than adolescents on health indicators, with many measures of negative outcomes--including rates of injury, homicide, and substance use--peaking during the young adult years. The contextual factors shaping health status and access to care in young adulthood differ significantly from the context of adolescence. This article synthesizes national data to present a health profile of young adults, reviewing social indicators that describe the context of young adulthood and presenting measures of health status. We examine mortality, morbidity, risky behaviors, and health care access and utilization, identifying the most significant gender and racial/ethnic disparities. The article also identifies limitations of existing data and offers suggestions for future research and health monitoring in this area. We conclude with a discussion of current efforts to address the health and well-being of young adults and argue for creating a national health agenda for young adults that includes research, programs and policies to address health issues during this period of the lifespan.

Costus speciosus is native to South East Asia, especially found in India, Srilanka, Indonesia and Malaysia. C. speciosus have numerous therapeutic potentials against a wide variety of complains. The therapeutic properties of C. speciosus are attributed to the presence of various ingredients such as alkaloids, flavonoids, glycosides, phenols, saponins, sterols and sesquiterpenes. This review presented the past, present, and the future status of C. speciosus active ingredients to propose a future use as a potential anticancer agent. All possible up-regulation of cellular apoptotic molecules as p53, p21, p27, caspases, reactive oxygen species (ROS) generation and others attribute to the anticancer activity of C. speciosus along the down-regulation of anti-apoptotic agents such as Akt, Bcl2, NFKB, STAT3, JAK, MMPs, actin, surviving and vimentin. Eventually, we recommend further investigation of different C. speciosus extracts, using some active ingredients and evaluate the anticancer effect of these chemicals against different cancers.

The management of anthrax remains a top priority among the biowarfare/bioterror agents. It was the Bacillus anthracis spore attack through the US mail system after the September 11, 2001, terrorist attacks in the USA that highlighted the potential of B. anthracis as a bioterrorism agent and the threat posed by its deliberate dissemination. These attacks invigorated the efforts toward understanding the anthrax pathogenesis and development of more comprehensive medical intervention strategies for its containment in case of both natural disease and manmade, accidental or deliberate infection of a non-suspecting population. Currently, efforts are directed toward the development of safe and efficacious vaccines as well as intervention tools for controlling the disease in the advanced fulminant stage when toxemia has already developed. This work presents an overview of the current understanding of anthrax pathogenesis and recent advances made, particularly after 2001, for the successful management of anthrax and outlines future perspectives.

Chen, Yousu; Huang, Zhenyu; Zhou, Ning

With the deployment of new smart grid technologies and the penetration of renewable energy in power systems, significant uncertainty and variability is being introduced into power grid operation. Traditionally, the Energy Management System (EMS) operates the power grid in a deterministic mode, and thus will not be sufficient for the future control center in a stochastic environment with faster dynamics. One of the main challenges is to improve situational awareness. This paper reviews the current status of power grid operation and presents a vision of improving wide-area situational awareness for a future control center. An advanced framework, consisting of parallelmore » state estimation, state prediction, parallel contingency selection, parallel contingency analysis, and advanced visual analytics, is proposed to provide capabilities needed for better decision support by utilizing high performance computing (HPC) techniques and advanced visual analytic techniques.

2016-09-01

Filamentous ascomycetes fungi have had important roles in natural cycles, and are already used industrially for e.g. supplying of citric, gluconic and itaconic acids as well as many enzymes. Faster human activities result in higher consumption of our resources and producing more wastes. Therefore, these fungi can be explored to use their capabilities to convert back wastes to resources. The present paper reviews the capabilities of these fungi in growing on various residuals, producing lignocellulose-degrading enzymes and production of organic acids, ethanol, pigments, etc. Particular attention has been on Aspergillus, Fusarium, Neurospora and Monascus genera. Since various species are used for production of human food, their biomass can be considered for feed applications and so biomass compositional characteristics as well as aspects related to culture in bioreactor are also provided. The review has been further complemented with future research avenues. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

A framework for the development, evaluation and assessment of (Q)SARs is presented together with several examples. A workflow for performing read-across predictions within category and analogue approaches is presented and the shortcomings discussed. In light of the advances in high throughput (HT) approaches and constructs such as adverse outcome pathways (AOPs) coming on-line to help in interpreting such HT data, the ways in which non-testing approaches are developed are also evolving. We discuss what the future of these approaches might look like and outline how their integration could be useful in screening toxicity for drug development.

Oman is located in the southeast of Arabian Peninsula with a relatively young population of about 3 831 553 people. The Ministry of Health, which is the healthcare provider, is facing a challenge with the increased levels of noncommunicable diseases including chronic kidney disease. A growing number of patients progress to end-stage kidney disease (ESKD), demanding renal replacement therapy. In 2014, there were 1339 of ESKD patients receiving dialysis and almost 1400 patients received kidney transplants. The estimated annual incidence of ESKD is 120 patients per million population. Diabetes mellitus and hypertensive nephropathy are the commonly identified causes of ESKD. Many patients with glomerulonephritis, systemic lupus erythematosus, nephrolithiasis, and inherited kidney disease present with advanced chronic kidney disease. This article reviews the current status of kidney disease in Oman and addresses the present and future needs, through a systematic-review of all related papers.

Controlled motion in an elastic world. Research project: Manipulation strategies for massive space payloads

NASA Technical Reports Server (NTRS)

Book, Wayne J.

1992-01-01

The flexibility of the drives and structures of controlled motion systems are presented as an obstacle to be overcome in the design of high performance motion systems, particularly manipulator arms. The task and the measure of performance to be applied determine the technology appropriate to overcome this obstacle. Included in the technologies proposed are control algorithms (feedback and feed forward), passive damping enhancement, operational strategies, and structural design. Modeling of the distributed, nonlinear system is difficult, and alternative approaches are discussed. The author presents personal perspectives on the history, status, and future directions in this area.

New particle formation (NPF) studies have been conducted in China since 2004. Formation of new atmospheric aerosol particles has been observed to take place in diverse environments, even under the circumstances of high pre-existing particle loading, challenging the traditional and present understanding of the physicochemical nucleation mechanisms, which have been proposed based on the investigations in clean environments and under laboratory experimental conditions. This paper summarizes the present status and gaps in understanding NPF in China and discusses the main directions opening for future research. Copyright © 2016 Elsevier B.V. All rights reserved.

1997-01-01

This first interim assessment of the subsonic assessment (SASS) project attempts to summarize concisely the status of our knowledge concerning the impacts of present and future subsonic aircraft fleets. It also highlights the major areas of scientific uncertainty, through review of existing data bases and model-based sensitivity studies. In view of the need for substantial improvements in both model formulations and experimental databases, this interim assessment cannot provide confident numerical predictions of aviation impacts. However, a number of quantitative estimates are presented, which provide some guidance to policy makers.

The bioassessment of aquatic ecosystems is currently based on various biotic indices that use the occurrence and/or abundance of selected taxonomic groups to define ecological status. These conventional indices have some limitations, often related to difficulties in morphological identification of bioindicator taxa. Recent development of DNA barcoding and metabarcoding could potentially alleviate some of these limitations, by using DNA sequences instead of morphology to identify organisms and to characterize a given ecosystem. In this paper, we review the structure of conventional biotic indices, and we present the results of pilot metabarcoding studies using environmental DNA to infer biotic indices. We discuss the main advantages and pitfalls of metabarcoding approaches to assess parameters such as richness, abundance, taxonomic composition and species ecological values, to be used for calculation of biotic indices. We present some future developments to fully exploit the potential of metabarcoding data and improve the accuracy and precision of their analysis. We also propose some recommendations for the future integration of DNA metabarcoding to routine biomonitoring programs. Copyright © 2018 Elsevier B.V. All rights reserved.

Climatic Changes, and more generaly Global Changes, play a major role in environmental modifications in relation with public health. Modifications of temperatures, precipitations... influence ecological habitats. These habitats can be adapted for some animals species, responsable of certain pandemics. Mosquitoes and birds represent for certain pandemics the essential elements of virus transmission. Abundance of mosquitoes and birds species, is heavily conditioned by flooded areas extent and specific habitats and their variations. The study we carried, has been done in South of France. We show present status of ecological habitats and flooded durations and future previsions. We reach environment impact for certain virus like West Nile virus. This virus affects bird, horse and sometimes man. Presence of the virus is conditioned by different factors, primarily including vector distribution (mosquitoes). We show how it's possible to localise favorable areas for the virus and to predict its future expansion areas. We present maps of the possibilities for future concerning previsions of bioclimatic steps variations. Thanks to the latest remote sensing and spatial analysis techniques. Our maps may be used as precious tools to help decision makers when faced with mosquito related problems.

Inland sea as a unit for environmental history: East Asian inland seas from prehistory to future.

PubMed

Lindstrom, Kati; Uchiyama, Junzo

2012-04-01

The boundaries of landscape policies often coincide with political or economic boundaries, thus creating a situation where a unit of landscape protection or management reflects more its present political status than its historico-geographical situation, its historical function and formation. At the same time, it is evident that no unit can exist independently of the context that has given birth to it and that environmental protection in isolated units cannot be very effective. The present paper will discuss inland sea as a landscape unit from prehistory to modern days and its implications for future landscape planning, using EastAsian inland sea (Japan Sea and East China Sea) rim as an example. Historically an area of active communication, EastAsian inland sea rim has become a politically very sharply divided area. The authors will bring examples to demonstrate how cultural communication on the inland sea level has influenced the formation of several landscape features that are now targets for local or national landscape protection programs, and how a unified view could benefit the future of landscape policies in the whole region.

Environmental compatibility of closed landfills - assessing future pollution hazards.

PubMed

Laner, David; Fellner, Johann; Brunner, Paul H

2011-01-01

Municipal solid waste landfills need to be managed after closure. This so-called aftercare comprises the treatment and monitoring of residual emissions as well as the maintenance and control of landfill elements. The measures can be terminated when a landfill does not pose a threat to the environment any more. Consequently, the evaluation of landfill environmental compatibility includes an estimation of future pollution hazards as well as an assessment of the vulnerability of the affected environment. An approach to assess future emission rates is presented and discussed in view of long-term environmental compatibility. The suggested method consists (a) of a continuous model to predict emissions under the assumption of constant landfill conditions, and (b) different scenarios to evaluate the effects of changing conditions within and around the landfill. The model takes into account the actual status of the landfill, hence different methods to gain information about landfill characteristics have to be applied. Finally, assumptions, uncertainties, and limitations of the methodology are discussed, and the need for future research is outlined.

Psychological Perspectives on Pathways Linking Socioeconomic Status and Physical Health

PubMed Central

Matthews, Karen A.; Gallo, Linda C.

2011-01-01

Low socioeconomic status (SES) is a reliable correlate of poor physical health. Rather than treat SES as a covariate, health psychology has increasingly focused on the psychobiological pathways that inform understanding why SES is related to physical health. This review assesses the status of research that has examined stress and its associated distress, and social and personal resources as pathways. It highlights work on biomarkers and biological pathways related to SES that can serve as intermediate outcomes in future studies. Recent emphasis on the accumulation of psychobiological risks across the life course is summarized and represents an important direction for future research. Studies that test pathways from SES to candidate psychosocial pathways to health outcomes are few in number but promising. Future research should test integrated models rather than taking piecemeal approaches to evidence. Much work remains to be done, but the questions are of great health significance. PMID:20636127

Health and vulnerability to poverty in Ghana: evidence from the Ghana Living Standards Survey Round 5

PubMed Central

2012-01-01

Background An understanding of the complex relationship between health status and welfare is crucial for critical policy interventions. However, the focus of most policies in developing regions has been on current welfare to the neglect of forward-looking welfare analysis. The absence of adequate research in the area of future poverty or vulnerability to poverty has also contributed to the focus on current welfare. The objectives of this study were to estimate vulnerability to poverty among households in Ghana and examine the relationship between health status and vulnerability to poverty. Method The study used cross section data from the Fifth Round of the Ghana Living Standards Survey (GLSS 5) with a nationally representative sample of 8,687 households from all administrative regions in Ghana. A three-step Feasible Generalized Least Squares (FGLS) estimation procedure was employed to estimate vulnerability to poverty and to model the effect of health status on expected future consumption and variations in future consumption. Vulnerability to poverty estimates were also examined against various household characteristics. Results Using an upper poverty line, the estimates of vulnerability show that about 56% of households in Ghana are vulnerable to poverty in the future and this is higher than the currently observed poverty level of about 29%. Households with ill members were vulnerable to poverty. Moreover, households with poor hygiene conditions were also vulnerable to future poverty. The vulnerability to poverty estimates were, however, sensitive to the poverty line used and varied with household characteristics. Conclusion The results imply that policies directed towards poverty reduction need to take into account the vulnerability of households to future poverty. Also, hygienic conditions and health status of households need not be overlooked in poverty reduction strategies. PMID:22827954

Relativity of Simultaneity and Eternalism: In Defense of the Block Universe

NASA Astrophysics Data System (ADS)

Peterson, Daniel; Silberstein, Michael

Ever since Hermann Minkowski's now infamous comments in 1908 concerning the proper way to view space-time, the debate has raged as to whether or not the universe should be viewed as a four-dimensional, unified whole wherein the past, present, and future are regarded as equally real or whether the views espoused by the possibilists, historicists, and presentists regarding the unreality of the future (and, for presentists, the past) are more accurate. Now, a century after Minkowski's proposed block universe first sparked debate, we present a new, more conclusive argument in favor of the eternalism. Utilizing an argument based on the relativity of simultaneity in the tradition of Putnam and Rietdijk and explicit novel but reasonable assumptions as to the nature of reality, we argue that the past, present, and future should be treated as equally real, thus ruling that presentism and other theories of time that bestow special ontological status to the past, present, or future are untenable. Finally, we respond to our critics who suggest that: (1) there is no metaphysical difference between the positions of eternalism and presentism, (2) the present must be defined as the "here" as well as the "now", or (3) presentism is correct and physicists' current understanding of relativity is incomplete because it does not incorporate a preferred frame. We call response 1 deflationary since it purports to dissolve or deconstruct the age-old debate between the two views and response 2 compatibilist because it does nothing to alter special relativity (SR), arguing instead that SR unadorned has the resources to save presentism. Response 3 we will call incompatibilist because it adorns SR in some way in order to save presentism a la some sort of preferred frame. We show that neither 1 nor 2 can save presentism and 3 is not well motivated at this juncture except as an ad hoc device to refute eternalism.

An update in the initial management of paediatric status epilepticus.

PubMed

Lawton, Ben; Davis, Tessa; Goldstein, Henry; Tagg, Andrew

2018-06-01

Over the last 2 years, algorithms for the optimal management of status epilepticus have changed, as the medical community has recognized the need to terminate seizures in status in a timely manner. Recent research has evaluated the different choices of benzodiazepine and has given consideration to second-line treatment options. There has been a move to examine alternatives to phenytoin (such as levetiracetam and lacosamide) as second-line agents. Valproate should be used cautiously in view of the potential side effects. Three ongoing trials [Established Staus Epilepticus Treatment Trial (ESETT), Convulsive Status Epilepticus Paediatric Trial (ConSEPT), and emergency treatment with levetiracetam or phenytoin in status epilepticus in children (EcLiPSE)] are comparing the efficacy of levetiracetam and phenytoin. Benzodiazepines remain the first-line agent of choice, although there is ongoing discussion about the mode of administration and the best drug to choose. The results of ESETT, ConSEPT, and EcLiPSE will affect our future management of status, as we give consideration to levetiracetam as an alternative to phenytoin. Other medications such as lacosamide may emerge in future algorithms too.

It gives a broad overview of important ecosystem variables to be investigated, such as biogeochemical cycles, primary and secondary production, species distribution, animal movements, habitats and pollutants. Some relevant legislative drivers are listed, as they provide one context in which ecosystem studies are undertaken. In addition to literature cited within the text the paper contains some useful web links to assist the reader in making an informed instrument choice, as the authors feel that the topic is so broad, it is impossible to discuss all relevant systems or to provide appropriate detail for those discussed. It is therefore an introduction to how and why ecosystem status is currently observed, what variables are quantified, from what platforms, using remote sensing or in-situ measurements, and gives examples of useful sensor based tools. Starting with those presently available, to those under development and also highlighting sensors not yet realised but desirable for future studies.

2016-06-01

Appropriate health policies for the supply of dentists have been an ongoing issue in many developed countries. The purpose of this study was to estimate the future distribution of dentists with different working statuses in Japan and to discuss policy implications about the supply of dentists in any country. This was a retrospective cohort study using data from the National Survey of Physicians, Dentists and Pharmacists for 1972-2012. Based on data from the 2010 and 2012 surveys, we calculated by means of a Markov model the future number of dentists with different working statuses until 2042 according to sex. We estimated that the total number of active dentists will decrease from 2012 to 2042. The number of active dentists per 1,000 population was predicted to reach a peak in 2018, decrease by 4.2% from 2012 to 2038, and thereafter slightly increase. With regard to working status, the number of dentists with their own practices per 1,000 people was predicted to have reached a peak in 2014 and decrease by 22.0% until 2042. We estimated that the number of dentists used in dental clinics per 1,000 population will increase continuously between 2012 and 2042 by 20.0%. Our study suggests that maintaining this supply of dentists may lead to maldistribution of their working status in the future. © 2016 American Association of Public Health Dentistry.

Irritability is defined as a low threshold to experience anger in response to frustration. It is one of the most common symptoms in youth and is part of the clinical presentation of several disorders. Irritability can present early in life and is a predictor of long-term psychopathology; yet, the diagnostic status of irritability is a matter of intense debate. In the present article, we address two main components of the debate regarding irritability in youth: the misdiagnosis of chronic irritability as pediatric bipolar disorder, and the proposal of a new diagnosis in the DSM-5, disruptive mood dysregulation disorder, whose defining symptoms are chronic irritability and temper outbursts.

In the present study, breeding values for canine congenital sensorineural deafness, the presence of blue eyes and patches have been predicted using multivariate animal models to test the reliability of the breeding values for planned matings. The dataset consisted of 6669 German Dalmatian dogs born between 1988 and 2009. Data were provided by the Dalmatian kennel clubs which are members of the German Association for Dog Breeding and Husbandry (VDH). The hearing status for all dogs was evaluated using brainstem auditory evoked potentials. The reliability using the prediction error variance of breeding values and the realized reliability of the prediction of the phenotype of future progeny born in each one year between 2006 and 2009 were used as parameters to evaluate the goodness of prediction through breeding values. All animals from the previous birth years were used for prediction of the breeding values of the progeny in each of the up-coming birth years. The breeding values based on pedigree records achieved an average reliability of 0.19 for the future 1951 progeny. The predictive accuracy (R2) for the hearing status of single future progeny was at 1.3%. Combining breeding values for littermates increased the predictive accuracy to 3.5%. Corresponding values for maternal and paternal half-sib groups were at 3.2 and 7.3%. The use of breeding values for planned matings increases the phenotypic selection response over mass selection. The breeding values of sires may be used for planned matings because reliabilities and predictive accuracies for future paternal progeny groups were highest.

We review several current aspects of dark matter theory and experiment. We overview the present experimental status, which includes current bounds and recent claims and hints of a possible signal in a wide range of experiments: direct detection in underground laboratories, gamma-ray, cosmic ray, x-ray, neutrino telescopes, and the LHC. We briefly review several possible particle candidates for a weakly interactive massive particle (WIMP) and dark matter that have recently been considered in the literature. We pay particular attention to the lightest neutralino of supersymmetry as it remains the best motivated candidate for dark matter and also shows excellent detection prospects. Finally we briefly review some alternative scenarios that can considerably alter properties and prospects for the detection of dark matter obtained within the standard thermal WIMP paradigm.
