    Full Text Available Kvote 2 optagelse (optagelsesprøver til medicinstudiet har vist sig at have virket beskyttende på tidligt studiefrafald sammenlignet med kvote 1 optagelse på Syddansk Universitet. Dette prospektive kohorte studie af de samme kohorter viser, at de lavere adgangsgivende karakterer i kvote 2 gruppen samtidigt kun var forbundet med lidt lavere bachelor karaktergennemsnit. Admission testing appears to be protective against early dropout compared to grade-based admission for undergraduate medical students at the University of Southern Denmark. This prospective cohort study shows that the lower entry grades of the admission tested students were simultaneously associated with obtaining only slightly lower medical school grades.

    Full Text Available  SAMMENDRAGMed utgangspunkt i data fra et populasjonsbasert utvalg av 7 992 norske tvillinger ble sammenhengenmellom gjentatte ørebetennelser og forhold under svangerskapet studert. Som parametre på intrauterinevekstforhold ble informasjon om fødselsvekt og gestasjonsalder fra Medisinsk Fødselsregister benyttet.Informasjon om rapporterte øreinfeksjoner ble basert på spørreskjemaer som ble besvart av tvillingene ialderen 18–25 år. Først studerte vi individuelle effekter av fødselsvekt og gestasjonsalder på forekomsten avotitis media (OM. Rapportert fødselsvekt hos individer med OM var signifikant lavere enn hos kontrollene,med en gjennomsnittsforskjell på 86 gram. Hos de som rapporterte OM var gjennomsnittlig gestasjonsalder3 dager kortere enn i kontrollmaterialet. Deretter beregnet vi effekten av fødselsvekt ved bruk av co-twinkontroll metoden. Blant monozygote (MZ tvillingpar gjenspeiler fødselsvektforskjeller innenfor tvillingparetintra-uterine miljøforskjeller. Blant dizygote (DZ par kan vektforskjellen være både genetiske ogmiljøbetinget. Ved sammenligning av fødselsvektforskjeller innenfor tvillingparene er tvillingen som ikkehar gjentatte øreinfeksjoner en matchet kontroll blant OM diskordante par. Resultatene antyder at lavfødselsvekt er en risikofaktor for otitis media. Gjennomsnittlig vektforskjell blant par diskordante for OMvar 48 gram, og den av tvillingen som ikke rapporterte OM hadde signifikant høyere fødselsvekt.Kværner KJ, Tambs K, Harris J, Magnus P. Do pregnancy-related factors influence the development ofotitis media? Nor J Epidemiol 1997; 7 (1: 55-58.  ENGLISH SUMMARYThe association between intrauterine growth, as measured by weight and gestational age, and the occurrenceof recurrent ear infections was studied using data from a population based sample of 7992 Norwegian twins.Perinatal measures were collected from the Medical Birth Registry, and reports of recurrent ear infectionswere based on questionnaires completed when the twins were aged 18-25. First, the individual effects ofbirth weight and gestational age on the occurrence of otitis media (OM were estimated. Birth weight amongindividuals who reported OM was significantly lower than for controls, with a mean weight difference of 86grams. The average difference in gestational age was 3 days shorter among individuals with a positivehistory of OM. Next, the effect of birth weight was estimated using a co-twin control application. AmongMZ twins within pair differences in birth weight reflect environmental differences experienced in utero.Among DZ pairs birth weight differences may be due to genetic and environmental differences. Among OMdiscordant pairs, the co-twin without a history of OM is a matched control for comparisons of intra-pairdifferences in birth weight. When within pair birth weight differences were compared, the co-twin without ahistory of OM was used as the matched control. Results indicated that lower birth weight may be a riskfactor for OM. The average birth weight difference among OM discordant pairs was 48 grams, with thecontrol twin weighing significantly more than the twin with a history of OM.

    Post-operative pain-management (PPM) should first of all be decided by the specific surgical procedure in each case, but it also seems that genetic polymorphism affects the clinical effects of the pharmacological treatment. In this article we summarize the existing evidence of the hypothesis...... that the A118G-variant of the µ-opioidreceptor-gene OPRM1 affects clinical response to opioids after gynaecological and abdominal surgery. If the genetic profile of each patient becomes easier accessible in the future, PPM might be planned accordingly to surgical procedure as well as to genetic profile...... to avoid post-operative pain and pharmacological adverse effects....

    Directory of Open Access Journals (Sweden)

    Berit Bungum

    2012-10-01

    Full Text Available The new curriculum for compulsory education in Norway defines “Technology and design” as a multidisciplinary area, and this area has received a relatively strong position in the curriculum for science. This article describes the process of defining Technology and design in the formal curriculum. It then presents an analysis of how the curriculum approaches Technology and design in various phases towards the final formal curriculum. The analysis focuses on how ideas from Design & Technology as a subject in England and Wales have influenced the formation of the curriculum, and what relationship between science and technology it communicates. It is concluded that there has been a shift from new ideas towards more traditional science content during the process. The new science curriculum nevertheless facilitates a “partnership approach” to science and technology teaching in Norwegian schools, rather than communicating a view of technology as “applied science”

    Full Text Available Big Data can revolutionize humanity. Hidden within the huge amounts and variety of the data we are creating we may find information, facts, social insights and benchmarks that were once virtually impossible to find or were simply inexistent. Large volumes of data allow organizations to tap in real time the full potential of all the internal or external information they possess. Big data calls for quick decisions and innovative ways to assist customers and the society as a whole. Big data platforms and product portfolio will help customers harness to the full the value of big data volumes. This paper deals with technical and technological issues related to handling big data volumes in the Big Data environment.

    Directory of Open Access Journals (Sweden)

    Emil Husted

    2012-09-01

    Full Text Available Megen forskning har beskæftiget sig med, hvordan sociale og organisatoriske processer ændres, når de finder sted i virtuelle rum. Denne artikel tager udgangspunkt i innovationsprocesser, hvor aktører forsøger at etablere virtuelle verdner som platform for professionel kommunikation, men i stedet for at fokusere på kommunikationsprocesser internt i virtuelle verdner vil artiklen stille spørgsmålstegn ved dikotomien mellem den fysiske og den virtuelle verden og undersøge materialitetens betydning for organiseringen af det virtuelle. Ved at anlægge et perspektiv inspireret af Aktør Netværks Teori vil artiklen argumentere for, at fysiske steder og objekter ikke blot fungerer som kontekst for innovationsprocesser, men tværtimod inddrages som strategiske ressourcer, der aktivt medskaber de virtuelle verdner. Empirisk funderes analysen i fem danske virksomheder og viser, hvordan virksomhederne benytter sig af fysiske steder og objekter som strategisk ressource i innovationsprocessen. Hermed bidrager artiklen til litteraturen omkring innovation inden for nye medier såsom virtuelle verdner.

  8. Harness cavitation to improve processing

    Pandit, A.G.; Moholkar, V.S. [Univ. of Bombay (India)

    1996-07-01

    Mention cavitation to most chemical engineers, and they undoubtedly think of it as an operational problem. Indeed, the rapid creation and then collapse of bubbles, which is after all what cavitation involves, can destroy pumps and erode other equipment. Cavitation, however, also can have a positive side--presuming it is designed for and not unplanned. In this article, the authors look at how cavitation can be harnessed to improve processes, and the mechanisms for inducing cavitation--ultrasonics and hydrodynamics--and their likely roles. Sonication, that is, the use of ultrasound, is the conventional approach for creating cavitation, and so they turn to it first. Over the past few years, a number of groups have attempted to solve the problem of scale-up and design of ultrasonic reactors. The authors review the systems that already exist and also explore a simpler and efficient alternative to the ultrasonic reactor, the hydrodynamic cavitation reactor.

    2017-06-01

    In an automobile parts design company, the customer satisfaction is one of the most important factors for product design. Therefore, the company employs all means to focus its product design process based on the various requirements of customers resulting in high number of design changes. The objective of this research is to improve the design process of the electric car harness that effects the production scheduling by using Fault Tree Analysis (FTA) and Failure Mode and Effect Analysis (FMEA) as the main tools. FTA is employed for root cause analysis and FMEA is used to ranking a High Risk Priority Number (RPN) which is shows the priority of factors in the electric car harness that have high impact to the design of the electric car harness. After the implementation, the improvements are realized significantly since the number of design change is reduced from 0.26% to 0.08%.

    Full Text Available Denne artikkelen handler om norske engelsklæreres kompetanse i å arbeide med barn som har et annet morsmål enn norsk, og som lærer engelsk som fremmedspråk. Problemstillingene er "Hva slags utdanning og kunnskap innen flerspråklighet har engelsklærere i Norge?," "I hvilken grad føler engelsklærere i Norge seg forberedt på å undervise i flerkulturelle og flerspråklige klasserom?" og "Hvilken type kunnskap, ferdigheter og ressurser føler de behov for?". Vi presenterer resultater fra en nasjonal spørreundersøkelse hvor i alt 176 engelsklærere deltok. I tillegg presenterer vi resultater fra fokusintervjuer med i alt fire lærere fra to skoler. Resultatene viser at selv om engelsklærerne til en viss grad føler seg forberedt på arbeid med elever som ikke har norsk som morsmål, har svært få av dem utdanning som fokuserer på flerspråklighet. Svarene fra spørreundersøkelsen og fra intervjuene viser at engelsklærerne gjerne vil ha mer kompetanse på dette området. Vi vil derfor understreke betydningen av utdanning i teori og praksis om flerspråklig utvikling og flerkulturell utdanningsteori, og ikke minst betydningen av tilgang til faglig utvikling som fokuserer på flerspråklighet i skolen og i samfunnet for engelsklærere i Norge.Nøkkelord: engelsklærere, kompetanse, språkpedagogisk kunnskap,flerspråklighet, lærerutdanningAbstractThis paper examines the extent to which English teachers in Norway are prepared to work with children whose mother tongue is not Norwegian, and who are acquiring English as a foreign language.

    Chu, Chung-Ching; Di Meglio, Paola; Nestle, Frank O

    2011-02-01

    The skin immune system harbors a complex network of dendritic cells (DCs). Recent studies highlight a diverse functional specialization of skin DC subsets. In addition to generating cellular and humoral immunity against pathogens, skin DCs are involved in tolerogenic mechanisms to ensure the maintenance of immune homeostasis, as well as in pathogenesis of chronic inflammation in the skin when excessive immune responses are initiated and unrestrained. Harnessing DCs by directly targeting DC-derived molecules or selectively modulate DC subsets is a convincing strategy to tackle inflammatory skin diseases. In this review we discuss recent advances underlining the functional specialization of skin DCs and discuss the potential implication for future DC-based therapeutic strategies.

    Dendritic cells (DC) are professional antigen presenting cells that are crucial for the induction of anti-tumor T cell responses. As a consequence, research has focused on the harnessing of DCs for therapeutic interventions. Although current strategies employing ex vivo-generated and tumor-antigen loaded DCs have been proven feasible, there are still many obstacles to overcome in order to improve clinical trial successes and offset the cost and complexity of customized cell therapy. This review focuses on one of these obstacles and a pivotal step for the priming of tumor-specific CD8{sup +} and CD4{sup +} T cells; the in vitro loading of DCs with tumor antigens.

    The harnessing of peptides in biomedical applications is a recent hot topic. This arises mainly from the general biocompatibility of peptides, as well as from the ease of tunability of peptide structure to engineer desired properties. The ease of progression from laboratory testing to clinical trials is evident from the plethora of examples available. In this review, we compare and contrast how three distinct self-assembled peptide nanostructures possess different functions. We have 1) nanofibrils in biomaterials that can interact with cells, 2) nanoparticles that can traverse the bloodstream to deliver its payload and also be bioimaged, and 3) nanotubes that can serve as cross-membrane conduits and as a template for nanowire formation. Through this review, we aim to illustrate how various peptides, in their various self-assembled nanostructures, possess great promise in a wide range of biomedical applications and what more can be expected.

    2017-12-01

    Full Text Available Traditional automated systems, such as industrial robots, are applied in well-structured environments, and many automated systems have a limited adaptability to deal with complexity and uncertainty; therefore, the applications of industrial robots in small- and medium-sized enterprises (SMEs are very limited. The majority of manual operations in SMEs are too complicated for automation. The rapidly developed information technologies (IT has brought new opportunities for the automation of manufacturing and assembly processes in the ill-structured environments. Note that an automation solution should be designed to meet the given requirements of the specified application, and it differs from one application to another. In this paper, we look into the feasibility of automated testing for electric cable harnesses, and our focus is on some of the generic strategies for the improvement of the adaptability of automation solutions. Especially, the concept of modularization is adopted in developing hardware and software to maximize system adaptability in testing a wide scope of products. A proposed system has been implemented, and the system performances have been evaluated by executing tests on actual products. The testing experiments have shown that the automated system outperformed manual operations greatly in terms of cost-saving, productivity and reliability. Due to the potential of increasing system adaptability and cost reduction, the presented work has its theoretical and practical significance for an extension for other automation solutions in SMEs.

    As part of the US Department of Energy's Scientific Discovery through Advanced Computing (SciDAC-2) program, science teams are tackling problems that require computational simulation and modeling at the petascale. A grand challenge for computer science is to develop software technology that makes it easier to harness the power of these systems to aid scientific discovery. As part of its activities, the SciDAC-2 Center for Scalable Application Development Software (CScADS) is building open source software tools to support efficient scientific computing on the emerging leadership-class platforms. In this paper, we describe two tools for performance analysis and tuning that are being developed as part of CScADS: a tool for analyzing scalability and performance, and a tool for optimizing loop nests for better node performance. We motivate these tools by showing how they apply to S3D, a turbulent combustion code under development at Sandia National Laboratory. For S3D, our node performance analysis tool helped uncover several performance bottlenecks. Using our loop nest optimization tool, we transformed S3D's most costly loop nest to reduce execution time by a factor of 2.94 for a processor working on a 50 3 domain

    Yang, Rui; Huang, Liang; Lai, Ying-Cheng; Grebogi, Celso; Pecora, Louis M

    2013-03-01

    Chaos has long been recognized to be generally advantageous from the perspective of control. In particular, the infinite number of unstable periodic orbits embedded in a chaotic set and the intrinsically sensitive dependence on initial conditions imply that a chaotic system can be controlled to a desirable state by using small perturbations. Investigation of chaos control, however, was largely limited to nonlinear dynamical systems in the classical realm. In this paper, we show that chaos may be used to modulate or harness quantum mechanical systems. To be concrete, we focus on quantum transport through nanostructures, a problem of considerable interest in nanoscience, where a key feature is conductance fluctuations. We articulate and demonstrate that chaos, more specifically transient chaos, can be effective in modulating the conductance-fluctuation patterns. Experimentally, this can be achieved by applying an external gate voltage in a device of suitable geometry to generate classically inaccessible potential barriers. Adjusting the gate voltage allows the characteristics of the dynamical invariant set responsible for transient chaos to be varied in a desirable manner which, in turn, can induce continuous changes in the statistical characteristics of the quantum conductance-fluctuation pattern. To understand the physical mechanism of our scheme, we develop a theory based on analyzing the spectrum of the generalized non-Hermitian Hamiltonian that includes the effect of leads, or electronic waveguides, as self-energy terms. As the escape rate of the underlying non-attracting chaotic set is increased, the imaginary part of the complex eigenenergy becomes increasingly large so that pointer states are more difficult to form, making smoother the conductance-fluctuation pattern.

  15. Edge and core dynamics in harness

    International Nuclear Information System (INIS)

    Ball, R.

    2007-01-01

    Resistive kink oscillations in tokamak plasmas are usually treated as core localized events, yet there there are several mechanisms by which they may interact with the edge dynamics. This suggests that we may regulate edge oscillatory behaviour, or ELMs, by harnessing the natural or contrived sawtooth period and amplitude. In this work I investigate core-edge oscillatory entrainment through direct propagation of heat pulses, inductive coupling, and global higher order resonance effects. In the core of auxiliary heated tokamak plasmas the ineluctable rhythm of slow buildup and rapid conversion of potential energy governs electron and heat radial transport. The growth phase of the sawtooth is accompanied by significant reconnection, then during the collapse the temperature and density in the core fall dramatically. There is evidence from experiments in reversed field pinch devices that ensuing energy fluxes can affect flow shear and confinement at the edge. The basis for this study is the dynamical (BDS) model for edge plasma behavior that was derived from electrostatic resistive MHD equations. The BDS model reflects the major qualitative features of edge dynamics that have been observed, such as L-H transitions and associated ELMs, hysteresis, and spontaneous reversal of poloidal shear flow. Under poorly dissipative conditions the transient behavior of the model can exhibit period-doubling, blue-sky, homoclinic, and other exotic bifurcations. Thus we might ask questions such as: Is it possible to mode-lock the edge dynamics to the core sawteeth? Can we induce, or prevent, a change in direction of shear flow? What about MHD effects? Is core-edge communication one way or is there some feedback? In the simplest prototype for coupled core-edge dynamics I model the sawtooth crash as a periodic power input to the edge potential energy reservoir. This is effected by coupling the BDS model to the dynamical system u = u(1 - u 2 - x 2 ) - ω s x, x = x(1-u 2 -x 2 ) + ω s u

  16. Advances and limitations of visual conditioning protocols in harnessed bees.

    2016-10-01

    Bees are excellent invertebrate models for studying visual learning and memory mechanisms, because of their sophisticated visual system and impressive cognitive capacities associated with a relatively simple brain. Visual learning in free-flying bees has been traditionally studied using an operant conditioning paradigm. This well-established protocol, however, can hardly be combined with invasive procedures for studying the neurobiological basis of visual learning. Different efforts have been made to develop protocols in which harnessed honey bees could associate visual cues with reinforcement, though learning performances remain poorer than those obtained with free-flying animals. Especially in the last decade, the intention of improving visual learning performances of harnessed bees led many authors to adopt distinct visual conditioning protocols, altering parameters like harnessing method, nature and duration of visual stimulation, number of trials, inter-trial intervals, among others. As a result, the literature provides data hardly comparable and sometimes contradictory. In the present review, we provide an extensive analysis of the literature available on visual conditioning of harnessed bees, with special emphasis on the comparison of diverse conditioning parameters adopted by different authors. Together with this comparative overview, we discuss how these diverse conditioning parameters could modulate visual learning performances of harnessed bees. Copyright © 2016 Elsevier Ltd.

    2018-02-01

    Full Text Available The ever-growing concerns about making buildings more energy efficient and increasing the share of renewable energy used in them, has led to the development of ultra-low carbon buildings or passive houses. However, a huge potential still exists to lower the hot water energy demand, especially by harnessing heat from waste water exiting these buildings. Reusing this heat makes buildings more energy-efficient and this source is considered as a third-generation renewable energy technology, both factors conforming to energy policies throughout the world. Based on several theoretical and experimental studies, the potential to harness non-industrial waste water is quite high. As an estimate about 3.5 kWh of energy, per person per day could be harnessed and used directly, in many applications. A promising example of such an application, are low temperature fourth generation District Heating grids, with decentralized sources of heat. At the moment, heat exchangers and heat pumps are the only viable options to harness non-industrial waste heat. Both are used at different scales and levels of the waste-water treatment hierarchical pyramid. Apart from several unfavourable characteristics of these technologies, the associated exergetic efficiencies are low, in the range of 20–50%, even when cascaded combinations of both are used. To tackle these shortcomings, several promising trends and technologies are in the pipeline, to scavenge this small-scale source of heat to a large-scale benefit.

    Microbial pathogenesis studies are typically performed with reference strains, thereby overlooking microbial intra-species virulence heterogeneity. Here we integrated human epidemiological and clinical data with bacterial population genomics to harness the biodiversity of the model foodborne pathogen Listeria monocytogenes and decipher the basis of its neural and placental tropisms. Taking advantage of the clonal structure of this bacterial species, we identify clones epidemiologically associated with either food or human central nervous system (CNS) and maternal-neonatal (MN) listeriosis. The latter are also most prevalent in patients without immunosuppressive comorbidities. Strikingly, CNS and MN clones are hypervirulent in a humanized mouse model of listeriosis. By integrating epidemiological data and comparative genomics, we uncovered multiple novel putative virulence factors and demonstrated experimentally the contribution of the first gene cluster mediating Listeria monocytogenes neural and placental tropisms. This study illustrates the exceptional power of harnessing microbial biodiversity to identify clinically relevant microbial virulence attributes. PMID:26829754

  9. Network harness: bundles of routes in public transport networks

    Science.gov (United States)

    Berche, B.; von Ferber, C.; Holovatch, T.

    2009-12-01

    Public transport routes sharing the same grid of streets and tracks are often found to proceed in parallel along shorter or longer sequences of stations. Similar phenomena are observed in other networks built with space consuming links such as cables, vessels, pipes, neurons, etc. In the case of public transport networks (PTNs) this behavior may be easily worked out on the basis of sequences of stations serviced by each route. To quantify this behavior we use the recently introduced notion of network harness. It is described by the harness distribution P(r, s): the number of sequences of s consecutive stations that are serviced by r parallel routes. For certain PTNs that we have analyzed we observe that the harness distribution may be described by power laws. These power laws indicate a certain level of organization and planning which may be driven by the need to minimize the costs of infrastructure and secondly by the fact that points of interest tend to be clustered in certain locations of a city. This effect may be seen as a result of the strong interdependence of the evolutions of both the city and its PTN. To further investigate the significance of the empirical results we have studied one- and two-dimensional models of randomly placed routes modeled by different types of walks. While in one dimension an analytic treatment was successful, the two dimensional case was studied by simulations showing that the empirical results for real PTNs deviate significantly from those expected for randomly placed routes.

    2015-01-01

    Full Text Available This paper makes a case for harnessing indigenous knowledge (IK for sustainable national development in Ghana. IK according to the World Bank is the basic component of any country’s knowledge system and it is upon this knowledge that scientific research builds. In Ghana the Government has recognized the need to harness IK for sustainable national development and has therefore incorporated it into the National Science, Technology and Innovation Development Programme. But there is no evidence however that scientific research in Ghana actually takes IK into consideration during the research process. This paper discusses the concept of indigenous knowledge, its relevance in scientific discourse and the need for harnessing it for national development in Ghana. A desk study was conducted using journal publications, research and technical reports, online databases and the internet. About sixty articles were analysed using the thematic synthesis method under the following broad headings: Importance of Indigenous knowledge, Indigenous forest foods, Indigenous medicines, IK and food security, the management and processing of IK and the protection of Indigenous Knowledge.The results of the study established the need to document the local knowledge using appropriate procedures and strategies. It also concludes by suggesting that IK in Ghana must be protected by law and integrated into formal science.

  12. A single Danio rerio hars gene encodes both cytoplasmic and mitochondrial histidyl-tRNA synthetases.

    Directory of Open Access Journals (Sweden)

    Ashley L Waldron

    Full Text Available Histidyl tRNA Synthetase (HARS is a member of the aminoacyl tRNA synthetase (ARS family of enzymes. This family of 20 enzymes is responsible for attaching specific amino acids to their cognate tRNA molecules, a critical step in protein synthesis. However, recent work highlighting a growing number of associations between ARS genes and diverse human diseases raises the possibility of new and unexpected functions in this ancient enzyme family. For example, mutations in HARS have been linked to two different neurological disorders, Usher Syndrome Type IIIB and Charcot Marie Tooth peripheral neuropathy. These connections raise the possibility of previously undiscovered roles for HARS in metazoan development, with alterations in these functions leading to complex diseases. In an attempt to establish Danio rerio as a model for studying HARS functions in human disease, we characterized the Danio rerio hars gene and compared it to that of human HARS. Using a combination of bioinformatics, molecular biology, and cellular approaches, we found that while the human genome encodes separate genes for cytoplasmic and mitochondrial HARS protein, the Danio rerio genome encodes a single hars gene which undergoes alternative splicing to produce the respective cytoplasmic and mitochondrial versions of Hars. Nevertheless, while the HARS genes of humans and Danio differ significantly at the genomic level, we found that they are still highly conserved at the amino acid level, underscoring the potential utility of Danio rerio as a model organism for investigating HARS function and its link to human diseases in vivo.

    2007-12-01

    Full Text Available Abstract Background The benefits of genomics and biotechnology are concentrated primarily in the industrialized world, while their potential to combat neglected diseases in the developing world has been largely untapped. Without building developing world biotechnology capacity to address local health needs, this disparity will only intensify. To assess the potential of genomics to address health needs in the developing world, the McLaughlin-Rotman Centre for Global Health, along with local partners, organized five courses on Genomics and Public Health Policy in the developing world. The overall objective of the courses was to collectively explore how to best harness genomics to improve health in each region. This article presents and analyzes the recommendations from all five courses. Discussion In this paper we analyze recommendations from 232 developing world experts from 58 countries who sought to answer how best to harness biotechnology to improve health in their regions. We divide their recommendations into four categories: science; finance; ethics, society and culture; and politics. Summary The Courses' recommendations can be summarized across the four categories listed above: Science - Collaborate through national, regional, and international networks - Survey and build capacity based on proven models through education, training, and needs assessments Finance - Develop regulatory and intellectual property frameworks for commercialization of biotechnology - Enhance funding and affordability of biotechnology - Improve the academic-industry interface and the role of small and medium enterprise Ethics, Society, Culture - Develop public engagement strategies to inform and educate the public about developments in genomics and biotechnology - Develop capacity to address ethical, social and cultural issues - Improve accessibility and equity Politics - Strengthen understanding, leadership and support at the political level for biotechnology

    Many therapeutically relevant natural products are biosynthesized by the action of giant mega-enzyme assembly lines. By leveraging the specificity, promiscuity, and modularity of assembly lines, a variety of strategies has been developed that enables the biosynthesis of modified natural products. This review briefly summarizes recent structural advances related to natural product assembly lines, discusses chemical approaches to probing assembly line structures in the absence of traditional biophysical data, and surveys efforts that harness the inherent or engineered promiscuity of assembly lines for the synthesis of non-natural polyketides and non-ribosomal peptide analogues.

    2009-01-01

    This article about the CO 2 sequestration is divided in eight parts. The first part concerns the question of why it is important to harness the carbon dioxide. The second part reviews the different technologies to harness it. In part three, the conditioning and transport of CO 2 are studied. Then, the question of geological storage is tackled. The economical aspect of the CO 2 sequestration makes the following part. The acceptability of a underground storage is evoked because of the risk relative to the CO 2 storage. Some examples and projects (Usa, Canada, France) are presented. The conclusion ends this article with the assurance that the CO 2 sequestration is possible, but expansive on the energy level and financing (double investment cost and increasing at least 30% for the production costs for the energy coming from coal). It should be realized on a big scale only if significant tax are imposed to the atmospheric releases in CO 2 as it is the case in the Norwegian example (Sleipner field). The storage potentials are important by calling for aquifer layers. The questions of law and acceptability by the public are uncertain but not insurmountable if we think to the aquifers under the seas. (N.C.)

    2014-07-01

    In this paper, by taking the 5-min high frequency data of the Shanghai Composite Index as example, we compare the forecasting performance of HAR-RV and Multifractal volatility, Realized volatility, Realized Bipower Variation and their corresponding short memory model with rolling windows forecasting method and the Model Confidence Set which is proved superior to SPA test. The empirical results show that, for six loss functions, HAR-RV outperforms other models. Moreover, to make the conclusions more precise and robust, we use the MCS test to compare the performance of their logarithms form models, and find that the HAR-log(RV) has a better performance in predicting future volatility. Furthermore, by comparing the two models of HAR-RV and HAR-log(RV), we conclude that, in terms of performance forecasting, the HAR-log(RV) model is the best model among models we have discussed in this paper.

    Full Text Available  SAMMENDRAGI perioden 1999-2001 vil det bli gjennomført tre kostholdsundersøkelser som til sammen skal kartlegge konsum avmatvarer med betydning for inntaket av miljøgifter i Norge, fortrinnsvis kadmium, kvikksølv, PCB og dioksiner.Disse giftene finnes hovedsakelig i krabbe, flatfisk, skjell, gjedde og abbor, lever eller nyre fra vilt og viltvoksendesopp. Fordi gjennomsnittskonsumet er lavt, spørres det ikke spesifikt om disse matvarene i landsdekkende kostholdsundersøkelsersom 'Norkost'. Hensikten med studien er å kunne gi en bedre beskrivelse av eksponeringsfordelingeni befolkningen med tanke på miljøgifter. Fordelingen er antakelig skjev, dvs. et stort antall personerventes å ha et lavt inntak og noen få personer ventes å ha et relativt høyt inntak av de undersøkte stoffene. Eventuelleukjente risikogrupper vil kunne avdekkes, og det er av stor interesse å undersøke hvor stor eksponeringen i deutsatte gruppene er.Del A av undersøkelsen er landsdekkende og omfatter en postal frekvensundersøkelse til 10 000 tilfeldig valgtepersoner mellom 18 og 79 år. Del B omfatter en postal frekvensundersøkelse til 6000 tilfeldig valgte personer i sekskommuner, der tre er kystkommuner og tre er innlandskommuner. Kommunene blir valgt ut fra kjennskap til godtilgang på de aktuelle matvarene. Vi antar at der tilgangen på matvarene er god, er konsumet høyere.

    Full Text Available Har Gabur is the carbide obtained from pig manure by burning. The fluorescent carbon dots (CDs of Har Gabur were successfully synthesized through simulating the digestion process of human gastrointestinal tract. Transmission Electron Microscope (TEM analysis showed that the average size of the prepared Har Gabur CDs was 4 nm, with good solubility in water and strong fluorescence under UV irradiation. The X-ray and Raman results showed that the Har Gabur CDs were mainly composed of oxygen “O” and carbon “C” elements, in the forms of “C=O” and “C-O.” The bond energy results showed that the nitrogen “N” atom presented as “C-N” form, which indicated that Har Gabur CDs also contain “N.” In photobleaching assay, Har Gabur CDs showed excellent light stability compared with ordinary organic dye, fluorescein, and Rhodamine B. The fluorescence intensity of Har Gabur CDs was fairly stable within a wide pH range of 3–10. When L-lysine and L-cysteine were applied for the passivation stage, the relative quantum yields were improved by 1.53 and 3.68 times, respectively. Finally, the fluorescence properties of Har Gabur CDs were tested in cells and zebrafish, illustrating that Har Gabur CD has potential in the application of biological labeling and imaging.

  9. A test harness for accelerating physics parameterization advancements into operations

    The process of transitioning advances in parameterization of sub-grid scale processes from initial idea to implementation is often much quicker than the transition from implementation to use in an operational setting. After all, considerable work must be undertaken by operational centers to fully test, evaluate, and implement new physics. The process is complicated by the scarcity of like-to-like comparisons, availability of HPC resources, and the ``tuning problem" whereby advances in physics schemes are difficult to properly evaluate without first undertaking the expensive and time-consuming process of tuning to other schemes within a suite. To address this process shortcoming, the Global Model TestBed (GMTB), supported by the NWS NGGPS project and undertaken by the Developmental Testbed Center, has developed a physics test harness. It implements the concept of hierarchical testing, where the same code can be tested in model configurations of varying complexity from single column models (SCM) to fully coupled, cycled global simulations. Developers and users may choose at which level of complexity to engage. Several components of the physics test harness have been implemented, including a SCM and an end-to-end workflow that expands upon the one used at NOAA/EMC to run the GFS operationally, although the testbed components will necessarily morph to coincide with changes to the operational configuration (FV3-GFS). A standard, relatively user-friendly interface known as the Interoperable Physics Driver (IPD) is available for physics developers to connect their codes. This prerequisite exercise allows access to the testbed tools and removes a technical hurdle for potential inclusion into the Common Community Physics Package (CCPP). The testbed offers users the opportunity to conduct like-to-like comparisons between the operational physics suite and new development as well as among multiple developments. GMTB staff have demonstrated use of the testbed through a

    2016-01-01

    The effectiveness of a drug is dependent on accumulation at the site of action at therapeutic levels, however, challenges such as rapid renal clearance, degradation or non-specific accumulation requires drug delivery enabling technologies. Albumin is a natural transport protein with multiple ligand binding sites, cellular receptor engagement, and a long circulatory half-life due to interaction with the recycling neonatal Fc receptor. Exploitation of these properties promotes albumin as an attractive candidate for half-life extension and targeted intracellular delivery of drugs attached by covalent conjugation, genetic fusions, association or ligand-mediated association. This review will give an overview of albumin-based products with focus on the natural biological properties and molecular interactions that can be harnessed for the design of a next-generation drug delivery platform.

  12. Harnessing Multiple Internal Reflections to Design Highly Absorptive Acoustic Metasurfaces

    Shen, Chen; Cummer, Steven A.

    2018-05-01

    The rapid development of metasurfaces has enabled numerous intriguing applications with acoustically thin sheets. Here we report the theory and experimental realization of a nonresonant sound-absorbing strategy using metasurfaces by harnessing multiple internal reflections. We theoretically and numerically show that the higher-order diffraction of thin gradient-index metasurfaces is tied to multiple internal reflections inside the unit cells. Highly absorbing acoustic metasurfaces can be realized by enforcing multiple internal reflections together with a small amount of loss. A reflective gradient-index acoustic metasurface is designed based on the theory, and we further experimentally verify the performance using a three-dimensional printed prototype. Measurements show over 99% energy absorption at the peak frequency and a 95% energy absorption bandwidth of around 600 Hz. The proposed mechanism provides an alternative route for sound absorption without the necessity of high absorption of the individual unit cells.

    Oceans, and particularly waves, offer a huge potential for energy harnessing all over the world. Nevertheless, the performance of current energy converters does not yet allow us to use the wave energy efficiently. However, new control techniques can improve the efficiency of energy converters. In this sense, the plant sensors play a key role within the control scheme, as necessary tools for parameter measuring and monitoring that are then used as control input variables to the feedback loop. Therefore, the aim of this work is to manage the rotational speed control loop in order to optimize the output power. With the help of outward looking sensors, a Maximum Power Point Tracking (MPPT) technique is employed to maximize the system efficiency. Then, the control decisions are based on the pressure drop measured by pressure sensors located along the turbine. A complete wave-to-wire model is developed so as to validate the performance of the proposed control method. For this purpose, a novel sensor-based flow controller is implemented based on the different measured signals. Thus, the performance of the proposed controller has been analyzed and compared with a case of uncontrolled plant. The simulations demonstrate that the flow control-based MPPT strategy is able to increase the output power, and they confirm both the viability and goodness. PMID:29439408

    Apparatus permitting the utilization of large volumes of water in the harnessing and extracting of a portion of the power generated by the rise and fall of ocean tides, ocean currents, or flowing rivers includes the provision of a dam, and a specialized single cavity chamber of limited size as compared with the water head enclosed by the dam, and an extremely high volume gating system in which all or nearly all of the water between the high and low levels on either side of the dam is cyclically gated through the single chamber from one side of the dam to the other so as to alternately provide positive air pressure and a partial vacuum within the single chamber. In one embodiment, the specialized chamber has a barrier at the bottom which divides the bottom of the chamber in half, large ports at the bottom of the chamber to permit inflow and outflow of high volumes of water, and ganged structures having a higher total area than that of corresponding ports, in which the structures form sluice gates to selectively seal off and open different sets of ports. In another embodiment, a single chamber is used without a barrier. In this embodiment, vertical sluice gates are used which may be activated automatically by pressures acting on the sluice gates as a result of ingested and expelled water.

  20. Health as foreign policy: harnessing globalization for health.

    Fidler, David P

    2006-12-01

    This paper explores the importance for health promotion of the rise of public health as a foreign policy issue. Although health promotion encompassed foreign policy as part of 'healthy public policy', mainstream foreign policy neglected public health and health promotion's role in it. Globalization forces health promotion, however, to address directly the relationship between public health and foreign policy. The need for 'health as foreign policy' is apparent from the prominence public health now has in all the basic governance functions served by foreign policy. The Secretary-General's United Nations (UN) reform proposals demonstrate the importance of foreign policy to health promotion as a core component of public health because the proposals embed public health in each element of the Secretary-General's vision for the UN in the 21st century. The emergence of health as foreign policy presents opportunities and risks for health promotion that can be managed by emphasizing that public health constitutes an integrated public good that benefits all governance tasks served by foreign policy. Any effort to harness globalization for public health will have to make health as foreign policy a centerpiece of its ambitions, and this task is now health promotion's burden and opportunity.

  1. Weakly supervised visual dictionary learning by harnessing image attributes.

    2014-12-01

    Bag-of-features (BoFs) representation has been extensively applied to deal with various computer vision applications. To extract discriminative and descriptive BoF, one important step is to learn a good dictionary to minimize the quantization loss between local features and codewords. While most existing visual dictionary learning approaches are engaged with unsupervised feature quantization, the latest trend has turned to supervised learning by harnessing the semantic labels of images or regions. However, such labels are typically too expensive to acquire, which restricts the scalability of supervised dictionary learning approaches. In this paper, we propose to leverage image attributes to weakly supervise the dictionary learning procedure without requiring any actual labels. As a key contribution, our approach establishes a generative hidden Markov random field (HMRF), which models the quantized codewords as the observed states and the image attributes as the hidden states, respectively. Dictionary learning is then performed by supervised grouping the observed states, where the supervised information is stemmed from the hidden states of the HMRF. In such a way, the proposed dictionary learning approach incorporates the image attributes to learn a semantic-preserving BoF representation without any genuine supervision. Experiments in large-scale image retrieval and classification tasks corroborate that our approach significantly outperforms the state-of-the-art unsupervised dictionary learning approaches.

    The scientific diaspora is a unique resource for U.S. universities. By drawing on the expertise, experience, and catalytic potential of diaspora scientists, universities can capitalize more fully on their diverse intellectual resources to make lasting contributions to global health. This article examines the unique contributions of the diaspora in international research collaborations, advantages of harnessing the diaspora and benefits to U.S. universities of fostering these collaborations, challenges faced by scientists who want to work with their home countries, examples of scientists engaging with their home countries, and specific strategies U.S. universities and donors can implement to catalyze these collaborations. The contributions of the diaspora to the United States are immense: International students enrolled in academic year 2007-2008 contributed an estimated $15 billion to the U.S. economy. As scientific research becomes increasingly global, the percentage of scientific publications with authors from foreign countries has grown from 8% in 1988 to 20% in 2005. Diaspora scientists can help build trusting relationships with scientists abroad, and international collaborations may improve the health of underserved populations at home. Although opportunities for diaspora networks are increasing, most home countries often lack enabling policies, infrastructure, and resources to effectively utilize their diaspora communities abroad. This article examines how some governments have successfully mobilized their scientific diaspora to become increasingly engaged in their national research agendas. Recommendations include specific strategies, including those that encourage U.S. universities to promote mini-sabbaticals and provide seed funding and flexible time frames.

    Quantum entanglement is a fundamental resource for secure information processing and communications, and hyperentanglement or high-dimensional entanglement has been separately proposed for its high data capacity and error resilience. The continuous-variable nature of the energy-time entanglement makes it an ideal candidate for efficient high-dimensional coding with minimal limitations. Here, we demonstrate the first simultaneous high-dimensional hyperentanglement using a biphoton frequency comb to harness the full potential in both the energy and time domain. Long-postulated Hong-Ou-Mandel quantum revival is exhibited, with up to 19 time-bins and 96.5% visibilities. We further witness the high-dimensional energy-time entanglement through Franson revivals, observed periodically at integer time-bins, with 97.8% visibility. This qudit state is observed to simultaneously violate the generalized Bell inequality by up to 10.95 standard deviations while observing recurrent Clauser-Horne-Shimony-Holt S-parameters up to 2.76. Our biphoton frequency comb provides a platform for photon-efficient quantum communications towards the ultimate channel capacity through energy-time-polarization high-dimensional encoding.

    Full Text Available We previously described the novel synthesis of a copper high-aspect ratio structure (CuHARS biohybrid material using cystine. While extremely stable in water, CuHARS is completely (but slowly degradable in cellular media. Here, integration of the CuHARS into cellulose matrices was carried out to provide added control for CuHARS degradation. Synthesized CuHARS was concentrated by centrifugation and then dried. The weighed mass was re-suspended in water. CuHARS was stable in water for months without degradation. In contrast, 25 μg/mL of the CuHARS in complete cell culture media was completely degraded (slowly in 18 days under physiological conditions. Stable integration of CuHARS into cellulose matrices was achieved through assembly by mixing cellulose micro- and nano-fibers and CuHARS in an aqueous (pulp mixture phase, followed by drying. Additional materials were integrated to make the hybrids magnetically susceptible. The cellulose-CuHARS composite films could be transferred, weighed, and cut into usable pieces; they maintained their form after rehydration in water for at least 7 days and were compatible with cell culture studies using brain tumor (glioma cells. These studies demonstrate utility of a CuHARS-cellulose biohybrid for applied applications including: (1 a platform for biomedical tracking and (2 integration into a 2D/3D matrix using natural products (cellulose.

    2013-03-01

    Sunflower rust, caused by Puccinia helianthi Schw., can result in significant yield losses in cultivated sunflower (Helianthus annuus L. var. macrocarpus Ckll.). HAR6 is a germplasm population resistant to most predominant rust races. The objectives of this study were to map the resistance factor present in HAR6 (R HAR6 ), and to provide and validate molecular tools for the identification of this gene for marker assisted selection purposes. Virulence reaction of seedlings for the F2 population and F2:3 families suggested that a single dominant gene confers rust resistance in HAR6-1, a selected rust resistance line from the original population. Genetic mapping with eight markers covered 97.4 cM of genetic distance on linkage group 13 of the sunflower consensus map. A co-dominant marker ZVG61 is the closest marker distal to R HAR6 at a genetic distance of 0.7 cM, while ORS581, a dominant marker linked in the coupling phase, is proximal to R HAR6 at a genetic distance of 1.5 cM. Validation of these markers was assessed by converting a susceptible line into a rust resistant isoline by means of marker assisted backcrossing. The application of these results to assist the breeding process and to design new strategies for rust control in sunflower is discussed.

    The European Space Agency's (ESA) comet-chasing Rosetta mission was launched in 2004, before social media became a popular tool for mainstream communication. By harnessing a range of platforms for communicating the key messages of this unprecedented mission as it reached its destination ten years later, new audiences were reached and a global impact was achieved. Rosetta-specific social media accounts - @ESA_Rosetta on Twitter, the Rosetta Mission Facebook page and the rosettamission Instagram account - were developed during 2013/14 and used alongside the traditional reporting line of the main ESA website and the Rosetta blog to build awareness about the mission. Coordinated with ESA's existing social media channels (Flickr, YouTube, G+, Twitter, Facebook and Livestream) and with the support of ESA's country desks and Rosetta partner agency accounts (including @philae2014), information could be shared in a number of European languages, ensuring a wide reach across Europe - and the world. We discuss the roles of the various social media accounts in supporting and promoting the competitions and social media campaigns that were built around the key mission milestones of 2014: waking up from deep space hibernation (January), arriving at Comet 67P/Churyumov-Gerasimenko (August) and naming the landing site for Philae ahead of the landing event in November. We discuss the different approach to each channel, such as the first person twitter accounts, the dialogue with and between blog users, and the discussions held live via G+ Hangouts with leading scientists and spacecraft operators. We compare and contrast the audiences, the interaction we had with them and how challenges were overcome. We also use the science-fiction-meets-science-fact Ambition short movie, and its "undercover" dissemination on social media, as an example of how the profile of the Rosetta mission was raised in a unique way. By using a variety of social media platforms to target different audiences with

    2011-03-01

    Within the frame of an action of the ONEMA-BRGM convention (Methodological approaches and tools for the protection of drinking water harnessing against diffuse pollutions), this study aims at developing a synthesis of isotopic geochemical tools to obtain the information required for the delimitation of harnessing supply areas. The report first describes the conventional tools: water molecule steady isotopes, radioactive isotopes, water dating tools, tools developed for another use, and artificial tracers. It presents the possible uses of natural and artificial tracers to determine parameters like flow directions, water residence duration, exchanges between aquifers and water sheet-river interactions. It gives an overview of knowledge on the use of isotopic methods to determine the origin of contaminants. It proposes a brief overview of a previous study of water sheets-rivers relationships. It finally discusses the use of geochemical and isotopic tools when delimiting supply areas for harnessing aimed at drinking water supply

    Yang, Feng; Pai, Yi-Chung

    2011-08-11

    Over-head-harness systems, equipped with load cell sensors, are essential to the participants' safety and to the outcome assessment in perturbation training. The purpose of this study was to first develop an automatic outcome recognition criterion among young adults for gait-slip training and then verify such criterion among older adults. Each of 39 young and 71 older subjects, all protected by safety harness, experienced 8 unannounced, repeated slips, while walking on a 7m walkway. Each trial was monitored with a motion capture system, bilateral ground reaction force (GRF), harness force, and video recording. The fall trials were first unambiguously indentified with careful visual inspection of all video records. The recoveries without balance loss (in which subjects' trailing foot landed anteriorly to the slipping foot) were also first fully recognized from motion and GRF analyses. These analyses then set the gold standard for the outcome recognition with load cell measurements. Logistic regression analyses based on young subjects' data revealed that the peak load cell force was the best predictor of falls (with 100% accuracy) at the threshold of 30% body weight. On the other hand, the peak moving average force of load cell across 1s period, was the best predictor (with 100% accuracy) separating recoveries with backward balance loss (in which the recovery step landed posterior to slipping foot) from harness assistance at the threshold of 4.5% body weight. These threshold values were fully verified using the data from older adults (100% accuracy in recognizing falls). Because of the increasing popularity in the perturbation training coupling with the protective over-head-harness system, this new criterion could have far reaching implications in automatic outcome recognition during the movement therapy.

Each trial was monitored with a motion capture system, bilateral ground reaction force (GRF), harness force and video recording. The fall trials were first unambiguously indentified with careful visual inspection of all video records. The recoveries without balance loss (in which subjects’ trailing foot landed anteriorly to the slipping foot) were also first fully recognized from motion and GRF analyses. These analyses then set the gold standard for the outcome recognition with load cell measurements. Logistic regression analyses based on young subjects’ data revealed that peak load cell force was the best predictor of falls (with 100% accuracy) at the threshold of 30% body weight. On the other hand, the peak moving average force of load cell across 1-s period, was the best predictor (with 100% accuracy) separating recoveries with backward balance loss (in which the recovery step landed posterior to slipping foot) from harness assistance at the threshold of 4.5% body weight. These threshold values were fully verified using the data from older adults (100% accuracy in recognizing falls). Because of the increasing popularity in the perturbation training coupling with the protective over-head-harness system, this new criterion could have far reaching implications in automatic outcome recognition during the movement therapy.

    Highlights: • The structure and electrical properties of HArF in spatial confinement are analyzed. • Orbital compression leads to decrease of bond lengths in the HArF molecule. • Spatial restriction causes a drop of the molecular (hyper)polarizabilities. • Spatial confinement reduces the electron correlation contribution to μ, α and β. - Abstract: A systematic study on the dipole moment and (hyper)polarizabilities of argon fluorohydride under spatial restriction was performed. Detailed analysis of the confinement induced changes in the structure of HArF is also presented. In order to render the influence of chemical compression on the properties in question a two-dimensional harmonic oscillator potential, mimicking a cylindrical confinement, was applied. Through the comparison of the results obtained for HArF with those of HF the effect of Ar insertion on the above properties was discussed. A hierarchy of ab initio methods including HF, MP2, CCSD and CCSD(T), has been employed to investigate the effect of orbital compression on the electron correlation contribution to the studied electric properties. It was observed that the external confining potential modifies the electronic contributions to the dipole moment and (hyper)polarizabilities of HArF. In particular, the first hyperpolarizability of HArF is remarkably smaller than that of the unconfined HArF molecule

    Engineering-oriented constraint of harness technology has much information and project information presents progressive changes along with the design. Therefore, how to handle conflict resolution quickly is a problem to be solved. Process model of con- flict detection is put forward according to characteristics of harness technology design engineering-oriented constraint, and then two problems of how to conduct conflict positioning and judgment of constraint rules are introduced in this paper. Afterwards in this pa- per, constraint information directed acyclic graph is established by classified project constraint information to solve the conflict posi- tioning problem; solution of constraint satisfaction problem is applied to realize judgment problem of constraint rules. Finally, exam- ple is used to analyze the method in this paper to further verify the correctness and effectiveness of this method.

    2015-03-01

    Avascular necrosis (AVN) of the femoral head is an irreversible complication seen in the treatment of developmental dysplasia of hip (DDH) with the Pavlik harness. Its incidence is reported to be low after successful reduction of the hip but high if the hip is not concentrically relocated. We aim to investigate its incidence after failed Pavlik harness treatment. We prospectively followed up a group of children who failed Pavlik harness treatment for DDH treated at our institution by the senior author between 1988 and 2001 and compared their rates of AVN with a group of children who presented late and hence were treated surgically. AVN was graded as described by Kalamchi and MacEwen and only grade 2 to 4 AVN was considered significant and included in the analysis. Thirty-seven hips were included in the failed Pavlik group (group 1) and 86 hips in the no Pavlik group (group 2). Ten hips in group 1 developed AVN (27%), whereas only 7 hips in group 2 (8%) developed AVN; the odds of developing AVN after failed Pavlik treatment was 4.7 (95% confidence interval, 1.3-14.1) (P=0.009) with a relative risk of 3.32 (range, 1.37 to 8.05). There was no statistically significant association observed with duration of splintage and severity of AVN (Spearman's correlation, -0.46; P=0.18). However, there was a positive correlation noted with age at presentation and severity of AVN. Therefore, we advise close monitoring of hips in the Pavlik harness and discontinue its use if the hips are not reduced within 3 weeks. Level III.

    Directory of Open Access Journals (Sweden)

    Grishakov Valeriy V.

    2013-12-01

    Full Text Available The items of riding horse harness (bits with psalia, stirrups, buckles, decorations of bridles are analyzed in the article on the basis of the materials from the Chulkovo (Murom burial ground site of the 8th-10th centuries, located on right bank of the Oka river. It has been established that the use of horse harness items by the Muroma culture population, which had left the Chulkovo burial ground, is in full correspondence with the general traditions of the Finno-Ugric peoples of the Volga river region characteristic of the 8th-10th centuries. The shapes of the bits correspond to both the steppe (bits with S-shaped and straight psalia and the local traditions (bits with two and three moving rings. A tendency to uniformity is observed in the tradition of stirrups production. The main differences of the Muroma burial grounds from the neighboring Mordovian ones consist in the presence of horse burials (not known among the Mordovians, and, on the other hand, in a practically complete lack of horse harness in the funeral set of human burials. It can be assumed that the importance of cavalry with the Muromа was lower than with the Mordovians who were living next to the steppe world.

    van Wyngaard, Josef D V; Meeske, Robin; Erasmus, Lourens J

    2018-03-01

    We describe here a cattle harness to attach a gas collection vessel to facilitate the sulfur hexafluoride (SF 6 ) tracer gas technique. The harness consists of 2 major components: (1) a lightweight, robust body fabricated from an equine surcingle or lunge roller with padded thoracic trapezius pressure points, a bespoke shaping shaft for spine support, and adjustable buckles on both sides; and (2) an elastic flank-strap to prevent the harness from dislodging. The spine support consists of stainless steel laminated with carbon fiber. This support minimizes the contact area with the animal's skin, relieves the spine area of pressure, and creates free flow of ambient air below the platform, reducing sweat accumulation and hence preventing skin lesions. The harness weighs approximately 1.2 kg, allows for attachment of 2 gas collection vessels (animal and background sample), and is cost effective. Copyright © 2018 American Dairy Science Association.

    Full Text Available Forming har gitt viktige bidrag til det helhetlige kunnskapssyn som lenge har vært dominerende i norsk barnehagepedagogikk, men fagfeltet er nå lavere prioritert i forhold til aktiviteter som er ment å fremme ferdigheter innenfor språk og matematikk. Debatten om kvalitet i norsk barnehage proble-matiserer krav om testing av små barns ferdigheter innenfor avgrensede kunnskapsområder. Med et formingsfaglig fokus er det av interesse å se nærmere på barnehagene i Reggio Emilia, Italia, der barns praktisk skapende virksomhet gis høy prioritet med et atelier i hver barnehage. Den anerkjente kvaliteten i disse barnehagene (Wingert & Kantrowitz, 1991; Gardner, 2001; Gardner, 2006 begrun-ner en nærmere undersøkelse av atelierets betydning i denne pedagogiske praksisen.Målsettingen med artikkelen er å belyse atelierets funksjon i barnehagene i Reggio Emilia, hvilken rolle estetisk skapende virksomhet oppfattes å ha i barns læring, og å undersøke den kompetansen som kreves av atelieristen med ansvar for arbeidet i atelieret. Artikkelens empiriske materiale er hentet inn gjennom et intervju med atelierist Vea Vecchi i april 2010.Med en fenomenologisk-hermeneutisk tilnærming drøftes metodiske spørsmål omkring kvalitativt intervju og behandling av kvalitative data ved hjelp av oversetter. Metodiske valg i forbindelse med intervjuet som er gjennomført diskuteres. Resultater av intervjuet presenteres og analyseres, og atelierets egenart og atelieristens kompetanse diskuteres.

    Full Text Available Moving bed biofilm reactors (MBBRs are an effective biotechnology for treating industrial wastewater.

Optimization of MBBR systems has largely focused on aspects of carrier design, while little attention has been paid to enhancing strategies for harnessing microbial biomass. Previously, our research group demonstrated that mixed-species biofilms can be harvested from an industrial wastewater inoculum [oil sands process water (OSPW] using the Calgary Biofilm Device (CBD. Moreover, the resultant biofilm communities had the capacity to degrade organic toxins (naphthenic acids—NAs that are found in OSPW. Therefore, we hypothesized that harnessing microbial communities from industrial wastewater, as biofilms, on MBBR carriers may be an effective method to bioremediate industrial wastewater.Here, we detail our methodology adapting the workflow employed for using the CBD, to generate inoculant carriers to seed an MBBR.In this study, OSPW-derived biofilm communities were successfully grown, and their efficacy evaluated, on commercially available MBBR carriers affixed within a modified CBD system. The resultant biofilms demonstrated the capacity to transfer biomass to recipient carriers within a scaled MBBR. Moreover, MBBR systems inoculated in this manner were fully active 2 days post-inoculation, and readily degraded a select population of NAs. Together, these findings suggest that harnessing microbial communities on carriers affixed within a modified CBD system may represent a facile and rapid method for obtaining functional inoculants for use in wastewater MBBR treatment systems.

    Full Text Available Graviola is one of the most accomplished natural anticancer therapists gaining popularity in recent times. Harnessing the full benefit from tapping all of its rich bioactive reservoirs is absolutely worthy and mandatory. It is in this regard that a well optimized extraction methodology gains paramount importance. In case of Graviola, no sophistication in terms of extraction methods is reported. A neoteric sonication cum microwave combined extraction technology was introduced that maximized the extraction process and minimized (7 min the extraction time. The extraction efficiency was validated based on the significant enrichment of bioactive ingredients in Graviola extracts following the sonication cum microwave combined protocol.

    Morgan and colleagues put forth a call to action for the transformation of the Canadian healthcare system through the adoption of a national chronic disease prevention and management (CDPM) strategy. They offer examples of best practices and national solutions including investment in clinical information technologies to help support improved care and outcomes. Although we acknowledge that the authors propose CDPM solutions that are headed in the right direction, more rapid deployment of solutions that harness the potential of advanced collaborative technologies is required. We provide examples of how technologies that exist today can help to accelerate the achievement of some key CDPM objectives.

    2004-06-01

    Experiments are reported on learning in virgin Africanized honey bee queens (Apis mellifera L.). Queens restrained in a "Pavlovian harness" received a pairing of hexanal odor with a 1.8-M feeding of sucrose solution. Compared to explicitly unpaired controls, acquisition was rapid in reaching about 90%. Acquisition was also rapid in queens receiving an unconditioned stimulus of "bee candy" or an unconditioned stimulus administered by worker bees. During extinction the conditioned response declines. The steepest decline was observed in queens receiving an unconditioned stimulus of bee candy. These findings extend previous work on learning of Afrianized honey bee workers to a population of queen bees.

    A quarter-century after the passage of the Americans with Disabilities Act (ADA, 1990 ), workplace accommodation is still a struggle for deaf employees and their managers. Many challenges are the result of communication barriers that can be overcome through much needed-although often absent-advocacy and training. This article highlights the literature on the employment of deaf individuals in the United States service industries of food service, retail, and hospitality conducted from 2000 to 2016. Exploring dimensions of both hiring and active workplace accommodation, suggestions are made for how social work advocates can harness information and strengthen their approaches for educating managers and supporting workers.

Lower extremity kinematics was assessed in the sagittal plane from the mean (meanRoM, standard deviation (SDRoM and coefficient of variation (CoVRoM of the hip, knee, and ankle ranges of motion (RoM, as well as from the sample entropy (SampEn and the largest Lyapunov exponent (LyE of the joints' angles. Wearing the harness increased the meanRoM of the hip, the SDRoM and the CoVRoM of the knee, and the SampEn and the LyE of the ankle. In particular, the harness effect sizes for both the SampEn and the LyE of the ankle were large, likely reflecting a meaningful decline in the neuromuscular stabilizing control of this joint. Conclusions Wearing a harness during treadmill walking marginally influences lower extremity kinematics, resulting in more or less subtle changes in certain kinematic variables. However, in cases where differences in gait patterns would be expressed through modifications in these variables, having subjects walk with a harness may mask or reinforce such differences.

    Radio telemetry has been an important research tool in waterfowl studies for >20 years, yet little effort has been made to evaluate potential effects of transmitters on the birds that carry them. As part of a 4-year mallard (Anas platyrhynchos) study in the prairie pothole region of North Dakota and Minnesota, we compared radio-marked and unmarked female mallards in terms of percent time observed feeding, resting, and preening; nest initiation date; and clutch size and egg volume. Radio-marked females carried a 23-g back-mounted transmitter attached with a 2-loop harness (Dwyer 1972). On average, radio-marked females tended to feed less, rest and preen more, initiate nests later, and lay smaller clutches and eggs than unmarked females. Thus, behavioral and reproductive data from ducks marked with back-mounted harness-attached transmitters may be biased. We recommend that new designs of radio packages be field tested and caution that effects may be masked under extreme environmental conditions.

    Malaysia is heavily dependent on fossil fuel for electricity generation. With the rapidly diminishing of its fuel reserve and the increasingly negative effects of fossil fuels to the environment, the government has begun to utilise bio-fuel and solar radiation for electricity generation. However, the potential of harnessing other renewable sources, particular ocean energy, in Malaysia has not been fully realised. Therefore, studies were carried out to identify the potential of harnessing ocean energy for electricity generation. The Princeton Ocean Model was used to create a three-dimensional numerical ocean model for Malaysia which was calibrated against measurement by a means of adjoint data assimilation approach. A set of reliable tidal speed and tidal elevation data was therefore generated to determine the types of tides available in Malaysia, the potential areas of installing marine current turbines (MCTs), the total amount of electricity to be generated by MCT, the economical viability and the environmental benefits of using MCT in Malaysia. This paper presents the findings on the studies, encompassing the technical, economical and environmental aspects of installing MCT in Malaysia. The results are critical to policy makers and the potential investors on tidal energy in Malaysia for decision making. It may also help the neighboring countries to realize the possible potential of their ocean energy for electricity generation. (author)

    Full Text Available Crosstalk in wiring harness has been studied extensively for its importance in the naval ships electromagnetic compatibility field. An effective and high-efficiency method is proposed in this paper for analyzing Statistical Characteristics of crosstalk in wiring harness with random variation of position based on Polynomial Chaos Expansion (PCE. A typical 14-cable wiring harness was simulated as the object of research. Distance among interfering cable, affected cable and GND is synthesized and analyzed in both frequency domain and time domain. The model of naval ships wiring harness distribution parameter was established by utilizing Legendre orthogonal polynomials as basis functions along with prediction model of statistical characters. Detailed mean value, mean square error, probability density function and reasonable varying range of crosstalk in naval ships wiring harness are described in both time domain and frequency domain. Numerical experiment proves that the method proposed in this paper, not only has good consistency with the MC method can be applied in the naval ships EMC research field to provide theoretical support for guaranteeing safety, but also has better time-efficiency than the MC method. Therefore, the Polynomial Chaos Expansion method.

    Health managers play a key role in ensuring that health services are responsive to the needs of the population. Participatory action research (PAR) is one of the approaches that have been used to strengthen managers' capacity. However, collated knowledge on elements for harnessing PAR to strengthen managers' capacity is missing. This paper bridges this gap by reviewing existing literature on the subject matter. A critical interpretive synthesis method was used to interrogate eight selected articles. These articles reported the use of PAR to strengthen health managers' capacity. The critical interpretive synthesis method's approach to analysis guided the synthesis. Here, the authors interpretively made connections and linkages between different elements identified in the literature. Finally, the Atun et al. (Heal Pol Plann, 25:104-111, 2010) framework on integration was used to model the elements synthesised in the literature into five main domains. Five elements with intricate bi-directional interactions were identified in the literature reviewed. These included a shared purpose, skilled facilitation and psychological safety, activity integration into organisational procedures, organisational support, and external supportive monitoring. A shared purpose of the managers' capacity strengthening initiative created commitment and motivation to learn. This purpose was built upon a set of facilitation skills that included promoting participation, self-efficacy and reflection, thereby creating a safe psychological space within which the managers interacted and learnt from each other and their actions. Additionally, an integrated intervention strengthened local capacity and harnessed organisational support for learning. Finally, supportive monitoring from external partners, such as researchers, ensured quality, building of local capacity and professional safety networks essential for continued learning. The five elements identified in this synthesis provide a basis upon

  16. Harnessing Invariant NKT Cells to Improve Influenza Vaccines: A Pig Perspective

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Invariant natural killer T (iNKT cells are an “innate-like” T cell lineage that recognize glycolipid rather than peptide antigens by their semi-invariant T cell receptors. Because iNKT cells can stimulate an extensive array of immune responses, there is considerable interest in targeting these cells to enhance human vaccines against a wide range of microbial pathogens. However, long overlooked is the potential to harness iNKT cell antigens as vaccine adjuvants for domestic animal species that express the iNKT cell–CD1d system. In this review, we discuss the prospect of targeting porcine iNKT cells as a strategy to enhance the efficiency of swine influenza vaccines. In addition, we compare the phenotype and tissue distribution of porcine iNKT cells. Finally, we discuss the challenges that must be overcome before iNKT cell agonists can be contemplated for veterinary use in livestock.

    Schools and school systems are increasingly asked to use evidence-based strategies to promote the health and well-being of students. The dissemination of school-based health promotion research, however, offers particular challenges to conventional approaches to dissemination. Schools and education systems are multifaceted organizations that sit within constantly shifting broader contexts. This article argues that health promotion dissemination needs to be rethought for school communities as complex systems and that this requires understanding and harnessing the dynamic ecology of the sociopolitical context. In developing this argument, the authors draw on their experience of the dissemination process of a multilevel school-based intervention in a complex educational context. Building on this experience, they argue for the need to move beyond conventional dissemination strategies to a focus on active partnerships between developers and users of school-based intervention research and offer a conceptual tool for planning dissemination.

    Harnessing the energy of thermonuclear fusion reactions is one of the greatest challenges of our time. Fusion, the nuclear reaction that powers the sun and stars would provide mankind with a safe, environmentally benign, and virtually limitless source of energy. Fusion can be tamed in machines called tokamaks. The ITER tokamak is the largest scientific cooperation project ever established, bringing together 35 nations representing more than half of the world's population and 85% of the planet's gross domestic product. In the summer of 2010, the building construction began in earnest. Seven years later, the progress accomplished, both on the construction site in France at Saint-Paul-les-Durance and in factories throughout the world, is spectacular. On the construction site, 2,000 workers are busy erecting and equipping the installation's 39 permanent buildings. The ITER tokamak is planned to enter into operation in 2025

    Blades for wind turbine to harness energy in the Malaysia low speed winds have been designed. During wind tunnel testing, wind turbine model using this type of blades has cut in speed of 1.5 m/s and turned at 450 rpm at 4 m/s wind. The blades, due to their critical dimensions of 1.2 m length, 5 cm thickness, tapered and 15 degree twist, were difficult to produce especially in large number. Several production methods have been studied but for economical mass production, fibreglass blades using CNC cutting mould were chosen. The blade and mould designs and the manufacturing processes are briefly outlined in this paper. (Author)

    2017-10-01

    The clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated (Cas) systems are RNA-guided sequence-specific prokaryotic antiviral immune systems. In prokaryotes, small RNA molecules guide Cas effector endonucleases to invading foreign genetic elements in a sequence-dependent manner, resulting in DNA cleavage by the endonuclease upon target binding. A rewired CRISPR/Cas9 system can be used for targeted and precise genome editing in eukaryotic cells. CRISPR/Cas has also been harnessed to target human pathogenic viruses as a potential new antiviral strategy. Here, we review recent CRISPR/Cas9-based approaches to combat specific human viruses in humans and discuss challenges that need to be overcome before CRISPR/Cas9 may be used in the clinic as an antiviral strategy.

  8. Transition through co-optation: Harnessing carbon democracy for clean energy

    Science.gov (United States)

    Meng, Kathryn-Louise

    This dissertation explores barriers to a clean energy transition in the United States. Clean energy is demonstrably viable, yet the pace of clean energy adoption in the U.S. is slow, particularly given the immediate threat of global climate change. The purpose of this dissertation is to examine the factors inhibiting a domestic energy transition and to propose pragmatic approaches to catalyzing a transition. The first article examines the current political-economic and socio-technical energy landscape in the U.S. Fossil fuels are central to the functioning of the American economy. Given this centrality, constellations of power have been constructed around the reliable and affordable access of fossil fuels. The fossil fuel energy regime is comprised of: political-economic networks with vested interests in continued fossil fuel reliance, and fixed infrastructure that is minimally compatible with distributed generation. A transition to clean energy threatens the profitability of fossil fuel regime actors. Harnessing structural critiques from political ecology and process and function-oriented socio-technical systems frameworks, I present a multi-level approach to identifying pragmatic means to catalyzing an energy transition. High-level solutions confront the existing structure, mid-level solutions harness synergy with the existing structure, and low-level solutions lie outside of the energy system or foster the TIS. This is exemplified using a case study of solar development in Massachusetts. Article two presents a case study of the clean energy technological innovation system (TIS) in Massachusetts. I examine the actors and institutions that support cleantech development. Further, I scrutinize the actors and institutions that help sustain the TIS support system. The concept of a catalyst is presented; a catalyst is an actor that serves to propel TIS functions. Catalysts are critical to facilitating anchoring. Strategic corporate partners are identified as powerful

    Malaysia relies heavily on fossil fuels to meet its energy demands. However, Malaysia has started to explore the use of other forms of renewable energy such as solar energy, biofuels and tidal power. This paper focused on the potential of harnessing tidal energy in Malaysia for electricity production. There are several sites with great potential for tidal energy conversion, which could supplement the energy needs of Malaysia while reducing greenhouse gas emissions. Illustrations were included to show the amplitude of the main harmonic component of the tidal range around Malaysia. The main harmonic component found in the region has a maximum amplitude of 1.4 m, confirming the potential of tidal energy in Malaysia's Ocean. Since the tidal cycle is highly predictable, it has the potential to be a very reliable renewable energy source. Two main approaches are being researched internationally to harness the energy from tides, notably the barrage approach and the tidal stream approach. For the barrage approach, a physical barrier is created within the sea, and a sluice gate controls the flow of sea water. In the tidal stream approach, horizontal axis turbines are placed in the path of tidal currents to generate electricity, similar to the operation of wind turbines. This paper described the flow velocity, power output, availability of power supply and monthly yield of turbines using both the barrage and tidal stream approaches. The study showed that for the barrage approach, there are 6 sites in Malaysia where 14,970 kWH of energy can be generated monthly with a single turbine with a 5 m long blade. The tidal stream approach showed equally promising results at 2 sites. It was concluded that tidal energy is a promising form of renewable energy because of its cyclic, reliable and predictable nature and the vast energy contained within it. According to United Kingdom Department of Trade and Industry, 10 per cent of the United Kingdom's electricity needs could be

    No disease-modifying therapies (DMT) for neurodegenerative diseases (NDs) have been established, particularly for Alzheimer's disease (AD) and Parkinson's disease (PD). It is unclear why candidate drugs that successfully demonstrate therapeutic effects in animal models fail to show disease-modifying effects in clinical trials. To overcome this hurdle, patients with homogeneous pathologies should be detected as early as possible. The early detection of AD patients using sufficiently tested biomarkers could demonstrate the potential usefulness of combining biomarkers with clinical measures as a diagnostic tool. Cerebrospinal fluid (CSF) biomarkers for NDs are being incorporated in clinical trials designed with the aim of detecting patients earlier, evaluating target engagement, collecting homogeneous patients, facilitating prevention trials, and testing the potential of surrogate markers relative to clinical measures. In this review we summarize the latest information on CSF biomarkers in NDs, particularly AD and PD, and their use in clinical trials. The large number of issues related to CSF biomarker measurements and applications has resulted in relatively few clinical trials on CSF biomarkers being conducted. However, the available CSF biomarker data obtained in clinical trials support the advantages of incorporating CSF biomarkers in clinical trials, even though the data have mostly been obtained in AD trials. We describe the current issues with and ongoing efforts for the use of CSF biomarkers in clinical trials and the plans to harness CSF biomarkers for the development of DMT and clinical routines. This effort requires nationwide, global, and multidisciplinary efforts in academia, industry, and regulatory agencies to facilitate a new era.

Producing supercritical fluids will require drilling wells and sampling fluids and rocks to depths of 3.5 to 5 km, and at temperatures of 450-600{sup o}C. The long-term plan is to drill and test a series of such deep boreholes in Iceland at the Krafla, the Hengill, and the Reykjanes high temperature geothermal systems. Beneath these three developed drill fields temperatures should exceed 550-650{sup o}C, and the occurrence of frequent seismic activity below 5 km, indicates that the rocks are brittle and therefore likely to be permeable. Modeling indicates that if the wellhead enthalpy is to exceed that of conventionally produced geothermal steam, the reservoir temperature must be higher than 450{sup o}C. A deep well producing 0.67 m3/sec steam ({approx}2400 m3/h) from a reservoir with a temperature significantly above 450{sup o}C could yield enough high-enthalpy steam to generate 40-50 MW of electric power. This exceeds by an order of magnitude the power typically obtained from conventional geothermal wells. (auth)

  14. LncRNAWiki: harnessing community knowledge in collaborative curation of human long non-coding RNAs

    Long non-coding RNAs (lncRNAs) perform a diversity of functions in numerous important biological processes and are implicated in many human diseases. In this report we present lncRNAWiki (http://lncrna.big.ac.cn), a wiki-based platform that is open-content and publicly editable and aimed at community-based curation and collection of information on human lncRNAs. Current related databases are dependent primarily on curation by experts, making it laborious to annotate the exponentially accumulated information on lncRNAs, which inevitably requires collective efforts in community-based curation of lncRNAs. Unlike existing databases, lncRNAWiki features comprehensive integration of information on human lncRNAs obtained from multiple different resources and allows not only existing lncRNAs to be edited, updated and curated by different users but also the addition of newly identified lncRNAs by any user. It harnesses community collective knowledge in collecting, editing and annotating human lncRNAs and rewards community-curated efforts by providing explicit authorship based on quantified contributions. LncRNAWiki relies on the underling knowledge of scientific community for collective and collaborative curation of human lncRNAs and thus has the potential to serve as an up-to-date and comprehensive knowledgebase for human lncRNAs.

    Phytochemicals from herbs and fermented legumes are excellent dietary sources of phenolic metabolites. These phenolics have importance not only as food preservatives but increasingly have therapeutic and pharmaceutical applications. The long-term research objecitves of the food biotechnology program at the University of Massachusetts are to elucidate the molecular and physiological mechanisms associated with synthesis of important health-related, therapeutic phenolic metabolites in food-related plants and fermented plant foods. Current efforts focus on elucidation of the role of the proline-linked pentose phosphate pathway in regulating the synthesis of anti-inflammatory compound, rosmarinic acid (RA). Specific aims of the current research efforts are: (i) To develop novel tissue culture-based selection techniques to isolate high RA-producing, shoot-based clonal lines from genetically heterogeneous, cross-pollinating species in the family Lamiaceae; (ii) To target genetically uniform, regenerated shoot-based clonal lines for: (a) preliminary characterization of key enzymes associated with the pentose phosphate pathway and linked to RA synthesis; (b) development of genetic transformation techniques for subsequent engineering of metabolic pathways associated with RA synthesis. These research objectives have substantial implications for harnessing the genetic and biochemical potential of genetically heterogeneous, food-related medicinal plant species. The success of this research also provides novel methods and strategies to gain access to metabolic pathways of pharmaceutically important metabolites from ginger, curcuma, chili peppers, melon or other food-related species with novel phenolics.

    Weight bearing by the spinal column during upright posture often plays a role in the common problem of low back pain. Therefore, we developed a non-ferromagnetic spinal compression harness to enable MRI investigations of the spinal column during axial loading. Human subjects were fitted with a Nest and a footplate which were connected by adjustable straps to an analog load cell. MRI scans of human subjects (5 males and 1 female with age range of 27-53 yrs) during loaded and unloaded conditions were accomplished with a 1.5 Tesla GE Signa scanner. Studies of two subjects undergoing sequentially increasing spinal loads revealed significant decreases (r(sup 2) = 0.852) in spinal length between T4 and L5 culminating in a 1.5 to 2% length decrease during loading with 75% body weight. Sagittal vertebral body angles of four subjects placed under a constant 50% body weight load for one hour demonstrated increased lordotic and kyphotic curvatures. In the lumbar spine, the L2 vertebral body experienced the greatest angular change (-3 deg. to -5 deg.) in most subjects while in the thoracic spine, T4 angles increased from the unloaded state by +2 deg. to +9 deg. Overall, our studies demonstrate: 1) a progressive, although surprisingly small, decrease in spinal length with increasing load and 2) relatively large changes in spinal column angulation with 50% body weight.

    Genome editing has enabled broad advances and novel approaches in studies of gene function and structure; now, emerging methods aim to precisely engineer post-transcriptional processes. Developing precise, efficient molecular tools to alter the transcriptome holds great promise for biotechnology and synthetic biology applications. Different approaches have been employed for targeted degradation of RNA species in eukaryotes, but they lack programmability and versatility, thereby limiting their utility for diverse applications. The CRISPR/Cas9 system has been harnessed for genome editing in many eukaryotic species and, using a catalytically inactive Cas9 variant, the CRISPR/dCas9 system has been repurposed for transcriptional regulation. Recent studies have used other CRISPR/Cas systems for targeted RNA degradation and RNA-based manipulations. For example, Cas13a, a Type VI-A endonuclease, has been identified as an RNA-guided RNA ribonuclease and used for manipulation of RNA. Here, we discuss different modalities for targeted RNA interference with an emphasis on the potential applications of CRISPR/Cas systems as programmable transcriptional regulators for broad uses, including functional biology, biotechnology, and synthetic biology applications.

  18. A new technology for harnessing the dye polluted water and dye collection in the chemical factory

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    A new technology for harnessing the dye polluted water and dyecollection was developed. It is based on the enhanced evaporation by using solar, wind, and air temperature energy and additional heat-electric energy. It consists of four parts: (1) evaporation carrier system (evaporation carrier and frame for evaporation carrier) for polluted water; (2) polluted water circulating system (pumping-spraying-collecting); (3) heating system; (4) workshop with polluted water reservoir-tanks and rainfall prevention roof. The polluted water was (heated in case necessary) sprayed to the evaporation carrier system and the water was evaporated when it moved in the space and downward along the carrier mainly by using natural (solar, wind, and air temperature energy). In case, when there is no roof for the carrier system, thepolluted water can be stored in the reservoirs (storage volume for about 20 days). The first 10-25 mm rainfall also need to be stored in the reservoirs to meet the state standard for discharging wastewater. The dye may be collected at the surface in the reservoir-tanks and the crystallized salt may be collected at the bottom plate. The black-color wastewater released by the factory is no more discharged to the surface water system of Taihu Lake Basin. About 2 kg dye and 200 kg industrial salt may be collected from each tone of the polluted water. The non-pollution production of dye may be realized by using this technology with environmental, economical and social benefits.

    The ability to adaptively exert control over negative emotions is associated with beneficial mental health outcomes. Less is known about the associated emotional sequelae surrounding controllable versus uncontrollable positive emotional experiences. The ability to harness positive emotions is of particular importance in populations involving disrupted positive emotion functioning. In the present study, participants engaged in a relived memory task in which they recalled either a controllable or uncontrollable past positive emotional experience in counterbalanced order, while concurrent experiential and autonomic responses were measured. Participants included adults with bipolar I disorder (BD; n = 32), major depression (MDD; n = 32), and or nonpsychiatric controls (CTLs; n = 31). Across all participants, reliving a controllable positive emotion experience was associated with exhibited increased respiratory sinus arrhythmia, an autonomic marker of regulatory control. Interestingly, only the MDD group reported increased positive emotion and decreased cardiovascular arousal when reliving an event involving uncontrollable positive emotion, compared to the BD and CTL groups. No other group differences emerged. These findings suggest that although controllable positive emotion experiences may be adaptive for most, individuals with a history of restricted affect and depressed mood may actually derive more pleasure from times of unharnessed happiness.

Neoplastic cells evade immune recognition through the programmed death (PD-1/PD-ligand immune checkpoint pathway. Several novel agents have been developed to restore the immune system’s ability to recognize and destroy cancer cells. Nivolumab and pembrolizumab are two anti-PD-1 antibodies that have demonstrated success in the treatment of refractory Hodgkin lymphoma. Harnessing the immune system’s ability to target neoplastic cells, ideally without the use of cytotoxic chemotherapeutic agents, is one way in which these novel agents are changing the therapeutic landscape in the treatment of lymphomas. Here, we review the emerging data regarding checkpoint inhibitors in the management of Hodgkin lymphoma, the unique adverse effects encountered with the use of these agents, and a practical approach to the management of these adverse effects. Additionally, we discuss upcoming trials that will further assess the promising future developments of checkpoint inhibition in the treatment of not only Hodgkin lymphoma but also other B cell lymphomas and myeloma. These agents offer immense promise of a future where many lymphomas can be treated without the toxic effects of chemotherapeutic agents.

    The extraction of wind power from unique configurations embedded in moving vehicles by using micro-turbine devices has been investigated. In such moving environments, the specific power of the air motion is much greater and less intermittent than in stationary wind turbines anchored to the ground in open atmospheric conditions. In a translational frame of reference, the rate of work done by the drag force acting on the wind harnessing device due the relative motion of air should be taken into account in the overall performance evaluation through an energy balance. A device with a venting tube has been tested that connects a high-pressure stagnating flow region in the front of the vehicle with a low-pressure region at its rear. Our analysis identified two key areas to focus on for potentially significant rewards: (1) Vehicles with high energy conversion efficiency which require a high mass flow rate through the venting duct, and (2) low efficiency vehicles with wakes, which will be globally affected by the introduction of the venting duct device in a manner that reduces their drag so that there is a net gain in power generation.

    Near infrared (NIR) microscopy enables noninvasive imaging in tissue, particularly in the NIR-II spectral range (1000-1400 nm) where attenuation due to tissue scattering and absorption is minimized. Lanthanide-doped upconverting nanocrystals are promising deep-tissue imaging probes due to their photostable emission in the visible and NIR, but these materials are not efficiently excited at NIR-II wavelengths due to the dearth of lanthanide ground-state absorption transitions in this window. Here, we develop a class of lanthanide-doped imaging probes that harness an energy-looping mechanism that facilitates excitation at NIR-II wavelengths, such as 1064 nm, that are resonant with excited-state absorption transitions but not ground-state absorption. Using computational methods and combinatorial screening, we have identified Tm(3+)-doped NaYF4 nanoparticles as efficient looping systems that emit at 800 nm under continuous-wave excitation at 1064 nm. Using this benign excitation with standard confocal microscopy, energy-looping nanoparticles (ELNPs) are imaged in cultured mammalian cells and through brain tissue without autofluorescence. The 1 mm imaging depths and 2 μm feature sizes are comparable to those demonstrated by state-of-the-art multiphoton techniques, illustrating that ELNPs are a promising class of NIR probes for high-fidelity visualization in cells and tissue.

    Industrial food-grade yeast strains are selected for traits that enhance their application in quality production processes. Wine yeasts are required to survive in the harsh environment of fermenting grape must, while at the same time contributing to wine quality by producing desirable aromas and flavors. For this reason, there are hundreds of wine yeasts available, exhibiting characteristics that make them suitable for different fermentation conditions and winemaking practices. As wine styles evolve and technical winemaking requirements change, however, it becomes necessary to improve existing strains. This becomes a laborious and costly process when the targets for improvement involve flavor compound production. Here, we demonstrate a new approach harnessing preexisting industrial yeast strains that carry desirable flavor phenotypes - low hydrogen sulfide (H(2) S) production and high ester production. A low-H(2) S Saccharomyces cerevisiae strain previously generated by chemical mutagenesis was hybridized independently with two ester-producing natural interspecies hybrids of S. cerevisiae and Saccharomyces kudriavzevii. Deficiencies in sporulation frequency and spore viability were overcome through use of complementary selectable traits, allowing successful isolation of several novel hybrids exhibiting both desired traits in a single round of selection. © 2012 Federation of European Microbiological Societies.

  5. A New 3D Printing Strategy by Harnessing Deformation, Instability, and Fracture of Viscoelastic Inks.

    2018-02-01

    Direct ink writing (DIW) has demonstrated great potential as a multimaterial multifunctional fabrication method in areas as diverse as electronics, structural materials, tissue engineering, and soft robotics. During DIW, viscoelastic inks are extruded out of a 3D printer's nozzle as printed fibers, which are deposited into patterns when the nozzle moves. Hence, the resolution of printed fibers is commonly limited by the nozzle's diameter, and the printed pattern is limited by the motion paths. These limits have severely hampered innovations and applications of DIW 3D printing. Here, a new strategy to exceed the limits of DIW 3D printing by harnessing deformation, instability, and fracture of viscoelastic inks is reported. It is shown that a single nozzle can print fibers with resolution much finer than the nozzle diameter by stretching the extruded ink, and print various thickened or curved patterns with straight nozzle motions by accumulating the ink. A quantitative phase diagram is constructed to rationally select parameters for the new strategy. Further, applications including structures with tunable stiffening, 3D structures with gradient and programmable swelling properties, all printed with a single nozzle are demonstrated. The current work demonstrates that the mechanics of inks plays a critical role in developing 3D printing technology. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Full Text Available The increasing usage of smart phones has compelled mobile technology to become a universal part of everyday life. From wearable gadgets to sophisticated implantable medical devices, the advent of mobile technology has completely transformed the healthcare delivery scenario. Self-report measures enabled by mobile technology are increasingly becoming a more time and cost efficient method of assessing real world health outcomes. But, amidst all the optimism, there are concerns also on adopting this technology as regulations and ethical considerations on privacy legislations of end users are unclear. In general, the healthcare industry functions on some stringent regulations and compliances to ensure the safety and protection of patient information. A couple of the most common regulations are Health Insurance Portability Accountability Act (HIPPA and Health Information Technology for Economic and Clinical Health (HITECH. To harness the true potential of mobile technology to empower stakeholders and provide them a common platform which seamlessly integrates healthcare delivery and research, it is imperative that challenges and drawbacks in the sphere are identified and addressed. In this age of information and technology, no stones should be left unturned to ensure that the human race has access to the best healthcare services without an intrusion into his/her confidentiality. This article is an overview of the role of tracking and self-monitoring devices in data collection for real world evidence/observational studies in context to feasibility, confounders and ethical considerations.

    We seek to develop a prototype software analytical tool to augment FDA regulatory reviewers' capacity to harness scientific literature reports in PubMed/MEDLINE for pharmacovigilance and adverse drug event (ADE) safety signal detection. We also aim to gather feedback through usability testing to assess design, performance, and user satisfaction with the tool. A prototype, open source, web-based, software analytical tool generated statistical disproportionality data mining signal scores and dynamic visual analytics for ADE safety signal detection and management. We leveraged Medical Subject Heading (MeSH) indexing terms assigned to published citations in PubMed/MEDLINE to generate candidate drug-adverse event pairs for quantitative data mining. Six FDA regulatory reviewers participated in usability testing by employing the tool as part of their ongoing real-life pharmacovigilance activities to provide subjective feedback on its practical impact, added value, and fitness for use. All usability test participants cited the tool's ease of learning, ease of use, and generation of quantitative ADE safety signals, some of which corresponded to known established adverse drug reactions. Potential concerns included the comparability of the tool's automated literature search relative to a manual 'all fields' PubMed search, missing drugs and adverse event terms, interpretation of signal scores, and integration with existing computer-based analytical tools. Usability testing demonstrated that this novel tool can automate the detection of ADE safety signals from published literature reports. Various mitigation strategies are described to foster improvements in design, productivity, and end user satisfaction.

  9. Harnessing structural darkness in the visible and infrared wavelengths for a new source of light

    KAUST Repository

    Huang, Jianfeng

    2015-10-19

    Engineering broadband light absorbers is crucial to many applications, including energy-harvesting devices and optical interconnects. The performances of an ideal absorber are that of a black body, a dark material that absorbs radiation at all angles and polarizations. Despite advances in micrometre-thick films, the absorbers available to date are still far from an ideal black body. Here, we describe a disordered nanostructured material that shows an almost ideal black-body absorption of 98-99% between 400 and 1,400 nm that is insensitive to the angle and polarization of the incident light. The material comprises nanoparticles composed of a nanorod with a nanosphere of 30 nm diameter attached. When diluted into liquids, a small concentration of nanoparticles absorbs on average 26% more than carbon nanotubes, the darkest material available to date. By pumping a dye optical amplifier with nanosecond pulses of 100 mW power, we harness the structural darkness of the material and create a new type of light source, which generates monochromatic emission (5 nm wide) without the need for any resonance. This is achieved through the dynamics of light condensation in which all absorbed electromagnetic energy spontaneously generates single-colour energy pulses. © 2016 Macmillan Publishers Limited.

    Cass, Julie A.

    Advances in microscopy and biotechnology have given us novel insights into cellular biology and physics. While bacteria were long considered to be relatively unstructured, the development of fluorescence microscopy techniques, and spatially and temporally resolved high-throughput quantitative studies, have uncovered that the bacterial cell is highly organized, and its structure rigorously maintained. In this thesis I will describe our gateTool software, designed to harness cell-to-cell variations to probe bacterial structure, and discuss two exciting aspects of structure that we have employed gateTool to investigate: (i) chromosome organization and the cellular mechanisms for controlling DNA dynamics, and (ii) the study of cell wall synthesis, and how the genes in the synthesis pathway impact cellular shape. In the first project, we develop a spatial and temporal mapping of cell-cycle-dependent chromosomal organization, and use this quantitative map to discover that chromosomal loci segregate from midcell with universal dynamics. In the second project, I describe preliminary time- lapse and snapshot imaging analysis suggesting phentoypical coherence across peptidoglycan synthesis pathways.

    2016-07-01

    Full Text Available This paper presents a demand response (DR framework that intertwines thermodynamic building models with a genetic algorithm (GA-based optimization method. The framework optimizes heating/cooling schedules of end-users inside a business park microgrid with local distributed generation from renewable energy sources (DG-RES based on two separate objectives: net load minimization and electricity cost minimization. DG-RES is treated as a curtailable resource in anticipation of future scenarios where the infeed of DG-RES to the regional distribution network could be limited. We test the DR framework with a case study of a refrigerated warehouse and an office building located in a business park with local PV generation. Results show the technical potential of the DR framework in harnessing the flexibility of the thermal masses from end-user sites in order to: (1 reduce the energy exchange at the point of connection; (2 reduce the cost of electricity for the microgrid end-users; and (3 increase the local utilization of DG-RES in cases where DG-RES exports to the grid are restricted. The results of this work can aid end-users and distribution network operators to reduce energy costs and energy consumption.

  12. Building mechanical Greenberger-Horne-Zeilinger and cluster states by harnessing optomechanical quantum steerable correlations

    Tan, Huatang; Wei, Yanghua; Li, Gaoxiang

    2017-11-01

    Greenberger-Horne-Zeilinger (GHZ) and cluster states are two typical kinds of multipartite entangled states and can respectively be used for realizing quantum networks and one-way computation. We propose a feasible scheme for generating Gaussian GHZ and cluster states of multiple mechanical oscillators by pulsed cavity optomechanics. In our scheme, each optomechanical cavity is driven by a blue-detuned pulse to establish quantum steerable correlations between the cavity output field and the mechanical oscillator, and the cavity outputs are combined at a beam-splitter array with given transmissivity and reflectivity for each beam splitter. We show that by harnessing the light-mechanical steerable correlations, the mechanical GHZ and cluster states can be realized via homodyne detection on the amplitude and phase quadratures of the output fields from the beam-splitter array. These achieved mechanical entangled states can be viewed as the output states of an effective mechanical beam-splitter array with the mechanical inputs prepared in squeezed states with the light-mechanical steering. The effects of detection efficiency and thermal noise on the achieved mechanical states are investigated. The present scheme does not require externally injected squeezing and it can also be applicable to other systems such as light-atomic-ensemble interface, apart from optomechanical systems.

    Full Text Available Since 2009, shortly after the global economic crisis of 2008, Greece has entered into a deep recession phase. The multifaceted presence of austerity is experienced in an increasing number of sectors of the country. The Greek transportation sector is not immune to this state of affairs. The ongoing crisis had a significant impact on its economic (investment, employment, exports-imports turnover as well as its operational (transportation intensity, throughput, performance aspects and capabilities. In this paper, a detailed mapping of these impacts is laid out, correlating transport-related characteristics, trends and estimations with the respective economic ones. Specifically, the paper presents analyses of the Greek passenger and freight transportation, following a data-driven approach over several areas. Findings show a substantial decrease of activities overall. Paradoxically, however, austerity can also be said to offer opportunities, such as the development of innovative, cost-effective and outward-looking business schemes, for handling transportation-related issues. In the face of these opportunities, authorities and stakeholders have recently turned their attention to ways of harnessing them as they may arise. The paper conducts a detailed analysis of these efforts to discover prospects for development in the midst of austerity, and highlights the steps currently being taken in that direction.

    2003-03-01

    Large astronomical Gossamer telescopes in space will need to employ large solar shields to safeguard the optics from solar radiation. These types of telescopes demand accurate controls to maintain telescope pointing over long integration periods. We propose an active solar shield system that harnesses radiation pressure to accurately slew and acquire new targets without the need for reaction wheels or thrusters. To provide the required torques, the solar shield is configured as an inverted, 4-sided pyramidal roof. The sloped roof interior surfaces are covered with hinged “tiles” made from piezoelectric film bimorphs with specular metallized surfaces. Nominally, the tiles lie flat against the roof and the sunlight is reflected outward equally from all sloped surfaces. However, when the tiles on one roof pitch are raised, the pressure balance is upset and the sunshade is pushed to one side. By judicious selection of the tiles and control of their lift angle, the solar pressure can be harvested to stabilize the spacecraft orientation or to change its angular momentum. A first order conceptual design performance analysis and the results from the experimental design, fabrication and testing of piezoelectric bimorph hinge elements will be presented. Next phase challenges in engineering design, materials technology, and systems testing will be discussed.

    Terrestrial land surface processes play a critical role in the Earth system; they have a profound impact on the global climate, food and energy production, freshwater resources, and biodiversity. One of the most fascinating yet challenging aspects of characterizing terrestrial ecosystems is their field-scale (˜30 m) spatial heterogeneity. It has been observed repeatedly that the water, energy, and biogeochemical cycles at multiple temporal and spatial scales have deep ties to an ecosystem's spatial structure. Current Earth system models largely disregard this important relationship leading to an inadequate representation of ecosystem dynamics. In this presentation, we will show how existing global environmental datasets can be harnessed to explicitly represent field-scale spatial heterogeneity in Earth system models. For each macroscale grid cell, these environmental data are clustered according to their field-scale soil and topographic attributes to define unique sub-grid tiles. The state-of-the-art Geophysical Fluid Dynamics Laboratory (GFDL) land model is then used to simulate these tiles and their spatial interactions via the exchange of water, energy, and nutrients along explicit topographic gradients. Using historical simulations over the contiguous United States, we will show how a robust representation of field-scale spatial heterogeneity impacts modeled ecosystem dynamics including the water, energy, and biogeochemical cycles as well as vegetation composition and distribution.

    2012-12-20

    Evolutionary approaches have done much to identify the pressures that select for cooperative sentiment. This helps us understand when and why cooperation will arise, and applied research shows how these pressures can be harnessed to promote various types of cooperation. In particular, recent evidence shows how opportunities to acquire a good reputation can promote cooperation in laboratory and applied settings. Cooperation can be promoted by tapping into forces like indirect reciprocity, costly signaling, and competitive altruism. When individuals help others, they receive reputational benefits (or avoid reputational costs), and this gives people an incentive to help. Such findings can be applied to promote many kinds of helping and cooperation, including charitable donations, tax compliance, sustainable and pro-environmental behaviors, risky heroism, and more. Despite the potential advantages of using reputation to promote positive behaviors, there are several risks and limits. Under some circumstances, opportunities for reputation will be ineffective or promote harmful behaviors. By better understanding the dynamics of reputation and the circumstances under which cooperation can evolve, we can better design social systems to increase the rate of cooperation and reduce conflict.

    Multiple hematological biomarkers (i.e. complete blood counts and serum chemistry parameters) were used in a multivariate linear-regression fit to create predictive algorithms for estimating the severity of hematopoietic acute radiation syndrome (H-ARS) using two different species (i.e. Goettingen Mini-pig and non-human primate (NHP) (Macacca mulatta)). Biomarker data were analyzed prior to irradiation and between 1-60 days (mini-pig) and 1-30 days (NHP) after irradiation exposures of 1.6-3.5 Gy (mini-pig) and 6.5 Gy (NHP) 60 Co gamma ray doses at 0.5-0.6 Gy min -1 and 0.4 Gy min -1 , respectively. Fitted radiation risk and injury categorization (RRIC) values and RRIC prediction percent accuracies were compared between the two models. Both models estimated H-ARS severity with over 80% overall predictive power and with receiver operating characteristic curve area values of 0.884 and 0.825. These results based on two animal radiation models support the concept for the use of a hematopoietic-based algorithm for predicting the risk of H-ARS in humans. (authors)

Fortement motivée sur le plan religieux, cette campagne visait aussi à la suppression de la consommation du qat. Plus de 200 000 arbustes de qat ont étés arrachés, auxquels on a substitué des caféiers et des manguiers. Les moyens pour générer les revenus alternatifs incluaient aussi l’élevage, l’apiculture, la planification du développement d’artisanat, à quoi s’ajoutaient des projets d’irrigation, des programmes éducatifs et des prêts sans intérêt pour les investissements dans d’autres secteurs économiques. Bien que cette campagne ait été entravée dès le début par une sécheresse sévère ainsi que par l’absence d’aide gouvernementale, il a abouti d’une part à une réduction réelle de la culture et de la consommation du qat, et à la diversification importante de l’activité économique des fermiers. Mais le projet a aussi entrainé une migration accrue de la campagne vers les villes et l’abandon de nombreuses terres cultivées. Cependant, malgré ces limites, ce projet, unique au Yémen par son haut niveau de la mobilisation sociale, apporte des leçons précieuses concernant les contraintes politiques et économiques qui pèsent sur toute tentative de développer une agriculture sans qat dans les montagnes du Yémen.In 1999, the Ismailî   Bohra Community in Yemen’s Harâz mountains launched a drug substitution programme in order to replace the cultivation of qat with other economic and social activities.

    Our energy consumption relies heavily on the three components of fossil fuels (oil, natural gas and coal) and nearly 83% of our current energy is consumed from those sources. The use of fossil fuels, however, has been viewed as a major environmental threat because of their substantial contribution to greenhouse gases which are responsible for increasing the global average temperature. Last four decades, scientists have been searching for alternative sources of energy which need to be environmentally clean, efficient, cost-effective, renewable, and sustainable. One of the promising sustainable sources of energy can be achieved by harnessing sun energy through silicon wafer, organic polymer, inorganic dye, and quantum dots based solar cells. Among them, quantum dots have an exceptional property in that they can excite multiple electrons using only one photon. These dots can easily be synthesized, processed in solution, and incorporated into solar cell application. Interestingly, the quantum dots solar cells can exceed the Shockley-Queisser limit; however, it is a great challenge for other solar cell materials to exceed the limit. Theoretically, the quantum dots solar cell can boost the power conversion efficiency up to 66% and even higher to 80%. Moreover, in changing the size of the quantum dots one can utilize the Sun’s broad spectrum of visible and infrared ranges. This review briefly overviews the present performance of different materials-based solar cells including silicon wafer, dye-sensitized, and organic solar cells. In addition, recent advances of the quantum dots based solar cells which utilize cadmium sulfide/selenide, lead sulfide/selenide, and new carbon dots as light harvesting materials has been reviewed. A future outlook is sketched as to how one could improve the efficiency up to 10% from the current highest efficiency of 6.6%. PMID:28348320

    Full Text Available Elucidating gene regulatory network (GRN from large scale experimental data remains a central challenge in systems biology. Recently, numerous techniques, particularly consensus driven approaches combining different algorithms, have become a potentially promising strategy to infer accurate GRNs. Here, we develop a novel consensus inference algorithm, TopkNet that can integrate multiple algorithms to infer GRNs. Comprehensive performance benchmarking on a cloud computing framework demonstrated that (i a simple strategy to combine many algorithms does not always lead to performance improvement compared to the cost of consensus and (ii TopkNet integrating only high-performance algorithms provide significant performance improvement compared to the best individual algorithms and community prediction. These results suggest that a priori determination of high-performance algorithms is a key to reconstruct an unknown regulatory network. Similarity among gene-expression datasets can be useful to determine potential optimal algorithms for reconstruction of unknown regulatory networks, i.e., if expression-data associated with known regulatory network is similar to that with unknown regulatory network, optimal algorithms determined for the known regulatory network can be repurposed to infer the unknown regulatory network. Based on this observation, we developed a quantitative measure of similarity among gene-expression datasets and demonstrated that, if similarity between the two expression datasets is high, TopkNet integrating algorithms that are optimal for known dataset perform well on the unknown dataset. The consensus framework, TopkNet, together with the similarity measure proposed in this study provides a powerful strategy towards harnessing the wisdom of the crowds in reconstruction of unknown regulatory networks.

    Derelict mines pose potential risks to environmental health. Several factors such as soil structure, organic matter, and nutrient content are the greatly affected qualities in mined soils. Soil microbial communities are an important element for successful reclamation because of their major role in nutrient cycling, plant establishment, geochemical transformations, and soil formation. Yet, microorganisms generally remain an undervalued asset in mined sites. The microbial diversity in derelict mine sites consists of diverse species belonging to four key phyla: Proteobacteria, Acidobacteria, Firmicutes, and Bacteroidetes. The activity of plant symbiotic microorganisms including root-colonizing rhizobacteria and ectomycorrhizal fungi of existing vegetation in the mined sites is very high since most of these microbes are extremophiles. This review outlines the importance of microorganisms to soil health and the rehabilitation of derelict mines and how microbial activity and diversity can be exploited to better plan the soil rehabilitation. Besides highlighting the major breakthroughs in the application of microorganisms for mined site reclamation, we provide a critical view on plant−microbiome interactions to improve revegetation at the mined sites. Also, the need has been emphasized for deciphering the molecular mechanisms of adaptation and resistance of rhizosphere and non-rhizosphere microbes in abandoned mine sites, understanding their role in remediation, and subsequent harnessing of their potential to pave the way in future rehabilitation strategies for mined sites. - Highlights: • Abandoned mines pose potential risks to human and environmental health. • Re-establishment of a self-sustaining vegetative cover at derelict mines is a major challenge. • Soil microbial communities are very important for successful reclamation of mined sites. • Role of microorganisms in soil function in derelict mines needs to be understood.

    The particle-in-cell kinetic plasma code VPIC has been migrated successfully to the world's fastest supercomputer, Roadrunner, a hybrid multi-core platform built by IBM for the Los Alamos National Laboratory. How this was achieved will be described and examples of state-of-the-art calculations in space science, in particular, the study of magnetic reconnection, will be presented. With VPIC on Roadrunner, we have performed, for the first time, plasma PIC calculations with over one trillion particles, >100× larger than calculations considered "heroic" by community standards. This allows examination of physics at unprecedented scale and fidelity. Roadrunner is an example of an emerging paradigm in supercomputing: the trend toward multi-core systems with deep hierarchies and where memory bandwidth optimization is vital to achieving high performance. Getting VPIC to perform well on such systems is a formidable challenge: the core algorithm is memory bandwidth limited with low compute-to-data ratio and requires random access to memory in its inner loop. That we were able to get VPIC to perform and scale well, achieving >0.374 Pflop/s and linear weak scaling on real physics problems on up to the full 12240-core Roadrunner machine, bodes well for harnessing these machines for our community's needs in the future. Many of the design considerations encountered commute to other multi-core and accelerated (e.g., via GPU) platforms and we modified VPIC with flexibility in mind. These will be summarized and strategies for how one might adapt a code for such platforms will be shared.

    Malaysia's heritage is extraordinarily rich. Heritage links people, places and things from our history to the present and to the future. Department of Muzeums and Antiquities work diligently at collecting and preserving the artifacts, written records, oral traditions, special places and lands that make up the Malaysia's history. Over the years our concept of cultural heritage and its role as a central part of the experience of our communities has expanded from a focus on objects and monuments to include our social structures, ways of life, beliefs and systems of knowledge. We seek answers in our attempts to promote the understanding and unity among people that have made our country a nation regardless of ethnic origins and religious affiliations, and to prolong the life essence of our rich heritage. We found a simple but yet, a meaningful answer; Harnessing Science and Technology for Preservation and Conservation of Cultural Heritage in Malaysia. Conservation has gained an increasing importance world over, as there is greater awareness and a sense of urgency about the need to conserve and preserve cultural heritages. Recent years are witnessing unprecedented growth in various fields of science and technology in Malaysia, such as materials technology, medical sciences, biotechnology, information and communications technology. Whichever perspective is used, it is clear that science forms an integral part of Malaysia's culture, in the past as well as now. Fulfilling a vital function as a carrier of knowledge and methodology, sciences places on our shoulders a strong obligation towards future generations. As Malaysians, we have been formed by our cultural heritage. Clearly, we must protect that heritage and continue to enrich and develop it, incorporating new knowledge, new insights, new ideas and new experience. (Author)

  6. Harnessing landscape heterogeneity for managing future disturbance risks in forest ecosystems

    In order to prevent irreversible impacts of climate change on the biosphere it is imperative to phase out the use of fossil fuels. Consequently, the provisioning of renewable resources such as timber and biomass from forests is an ecosystem service of increasing importance. However, risk factors such as changing disturbance regimes are challenging the continuous provisioning of ecosystem services, and are thus a key concern in forest management. We here used simulation modeling to study different risk management strategies in the context of timber production under changing climate and disturbance regimes, focusing on a 8127 ha forest landscape in the Northern Front Range of the Alps in Austria. We show that under a continuation of historical management, disturbances from wind and bark beetles increase by +39.5% on average over 200 years in response to future climate change. Promoting mixed forests and climate-adapted tree species as well as increasing management intensity effectively reduced future disturbance risk. Analyzing the spatial patterns of disturbance on the landscape, we found a highly uneven distribution of risk among stands (Gini coefficients up to 0.466), but also a spatially variable effectiveness of silvicultural risk reduction measures. This spatial variability in the contribution to and control of risk can be used to inform disturbance management: Stands which have a high leverage on overall risk and for which risks can effectively be reduced (24.4% of the stands in our simulations) should be a priority for risk mitigation measures. In contrast, management should embrace natural disturbances for their beneficial effects on biodiversity in areas which neither contribute strongly to landscape-scale risk nor respond positively to risk mitigation measures (16.9% of stands). We here illustrate how spatial heterogeneity in forest landscapes can be harnessed to address both positive and negative effects of changing natural disturbance regimes in

    2014-01-01

    Background There is a substantial paucity of studies concerning musculoskeletal injuries in harness Standardbred racehorses. Specifically, little is known about the epidemiology of exercise-related musculoskeletal injuries. Most studies on this subject involve Thoroughbred racehorses, whose biomechanics and racing speed differ from Standardbred, making comparisons difficult. Here, a population of Standardbred racehorses trained at the same racecourse was studied over four years and a classification system for exercise-related musculoskeletal injuries was designed. The incidence rates of musculoskeletal injuries causing horses’ withdrawal from training for 15 days or longer were investigated. A mixed-effects Poisson regression model was used to estimate musculoskeletal injury rates and to describe significance of selected risk factors for exercise-related injuries in this population. Results A total of 356 trotter racehorses from 10 different stables contributed 8961 months at risk of musculoskeletal injuries. Four-hundred-and-twenty-nine injuries were reported and classified into 16 categories, based on their aetiology and anatomical localisation. The overall exercise-related injury rate was 4.79 per 100 horse months. When considering risk factors one by one in separate univariable analyses, we obtained the following results: rates did not differ significantly between genders and classes of age, whereas one driver seemed to cause fewer injuries than the others. Racing speed and racing intensity, as well as recent medical history, seemed to be significant risk factors (p fracture are lower in Standardbreds compared to Thoroughbreds, whereas the opposite is true for tendon and suspensory ligament injuries. In addition to identification of risk factors for musculoskeletal injuries among Standardbred racehorses, results suggest that racing intensity seems to be a protective predictor of risk and recent medical history could be used to identify horses at risk of

  9. The HARNESS Workbench: Unified and Adaptive Access to Diverse HPC Platforms

    2012-03-20

    The primary goal of the Harness WorkBench (HWB) project is to investigate innovative software environments that will help enhance the overall productivity of applications science on diverse HPC platforms. Two complementary frameworks were designed: one, a virtualized command toolkit for application building, deployment, and execution, that provides a common view across diverse HPC systems, in particular the DOE leadership computing platforms (Cray, IBM, SGI, and clusters); and two, a unified runtime environment that consolidates access to runtime services via an adaptive framework for execution-time and post processing activities. A prototype of the first was developed based on the concept of a 'system-call virtual machine' (SCVM), to enhance portability of the HPC application deployment process across heterogeneous high-end machines. The SCVM approach to portable builds is based on the insertion of toolkit-interpretable directives into original application build scripts. Modifications resulting from these directives preserve the semantics of the original build instruction flow. The execution of the build script is controlled by our toolkit that intercepts build script commands in a manner transparent to the end-user. We have applied this approach to a scientific production code (Gamess-US) on the Cray-XT5 machine. The second facet, termed Unibus, aims to facilitate provisioning and aggregation of multifaceted resources from resource providers and end-users perspectives. To achieve that, Unibus proposes a Capability Model and mediators (resource drivers) to virtualize access to diverse resources, and soft and successive conditioning to enable automatic and user-transparent resource provisioning. A proof of concept implementation has demonstrated the viability of this approach on high end machines, grid systems and computing clouds.

  19. Harnessing electro driven separation technique for the separation of selected agrochemicals

    International Nuclear Information System (INIS)

    2008-01-01

    Electro driven separation techniques offer a different approach to the analysis of complex mixtures than do traditional pressure-driven chromatographic system; it may rely on electrophoresis, the transport of charged species through a medium by an applied field or may rely on electro driven mobile phase to provide a true chromatographic separation. In the current work the potential of an electro driven separation technique viz. Micellar electrokinetic chromatography (MEKC), is harnessed for the separation of selected agrochemicals (organophosphorus pesticides, OPPs) widely used in the agriculture sector in Malaysia. The current study compares the use of MEKC in normal mode (NM) and reverse mode (RM) for the separation of the selected OPPS. This study also highlights the difference in separations produced by performing separations in normal mode-MEKC (NM-MEKC) and reverse mode-MEKC (RM-MEKC) for the selected OPPs. In RM-MEKC, separation is conducted at acidic pH (pH 2.5 in the current work) where the electro osmotic flow (EOF) is weak whereas in NM-MEKC, the separation is carried out under basic pH (9.3 in this work) where the EOF is strong. A reverse migration order of the OPPs was observed under RM-MEKC. Separation under NM-MEKC was found to be superior to those of RM- MEKC. A comparison is also made between separations performed under sweeping-NM-MEKC and sweeping-RM-MEKC. In sweeping, the OPPs are prepared in the same background solution (BGS) minus the micelles and is adjusted to the same conductivity as the BGS. The study showed that NM-MEKC is more sensitive than RM-MEKC but sweeping-RM-MEKC is superior to sweeping-NM-MEKC. However, sweeping-RM-MEKC only separates two of the OPPs in a single run whereas sweeping-NM-MEKC separates four OPPs in a single run. The better choice of separation mode would be sweeping-NM- MEKC for more OPPs separation in a single run. (author)

    To date, most studies of the human dimensions of decision making in avalanche terrain has focused on two areas - post-accident analysis using accident reports/interviews and, the development of tools as decision forcing aids. We present an alternate method using crowd-sourced citizen science, for understanding decision-making in avalanche terrain. Our project combines real-time GPS tracking via a smartphone application, with internet based surveys of winter backcountry users as a method to describe and quantify travel practices in concert with group decision-making dynamics, and demographic data of participants during excursions. Effectively, we use the recorded GPS track taken within the landscape as an expression of the decision making processes and terrain usage by the group. Preliminary data analysis shows that individual experience levels, gender, avalanche hazard, and group composition all influence the ways in which people travel in avalanche terrain. Our results provide the first analysis of coupled real-time GPS tracking of the crowd while moving in avalanche terrain combined with psychographic and demographic correlates. This research will lead to an improved understanding of real-time decision making in avalanche terrain. In this paper we will specifically focus on the presentation of the methods used to solicit, and then harness the crowd to obtain data in a unique and innovative application of citizen science where the movements within the terrain are the desired output data (Figure 1). Figure 1: Example GPS tracks sourced from backcountry winter users in the Teton Pass area (Wyoming), from the 2014-15 winter season, where tracks in red represent those recorded as self-assessed experts (as per our survey), and where tracks in blue represent those recorded as self-assessed intermediates.

    2005-01-01

    Pakistan has a population of 140 million with more than 30% of the population living in cities and towns. Karachi, the major port city of the country, is the most densely populated with a population crossing the 11 million mark. The city receives 435 MGD of drinking water from the River Indus and other sources. However, the net demand for the year 2000 was 594 MGD thus there is a gap of 159 MGD in demand and supply. Statistics show that the water demand in Karachi is increasing at the rate of 100 MGD every five years. The coastal belt of the country extends to 1046 sq. km. Of this, 930 km is from the Karachi to Gwader region in the province of Baluchistan. Most of the coastal areas lie outside the monsoon system of weather and therefore the climate is extremely dry. The annual rainfall in this belt is about 15 cms. Therefore, fresh water availability is a major factor for development of the coastal belt of Pakistan. In the wake of the looming water crisis it is becoming increasingly clear that all available and appropriate technologies, including nuclear and related technologies, have to be used for the sustainable development and management of freshwater resources in Pakistan. One particular approach is the desalination of seawater, and countries are increasing their capacity to harness the seas for tapping fresh water. The prospects of using nuclear energy for seawater desalination on a large scale are attractive since desalination is an energy intensive process. Pakistan Atomic Energy Commission (PAEC) is planning to actively participate in the activities of IAEA in the field of nuclear desalination by offering one of its nuclear power plants for coupling a demonstration nuclear desalination plant. Karachi Nuclear Power Plant (KANUPP), which is the country's first nuclear plant has been successfully operating for the last 30 years. This plant is proposed to be used as a potential site for installation of a demonstration nuclear desalination plant. KANUPP is

    Today's digital technologies can have a powerful influence on teaching and learning. M-learning and u-learning in particular are changing pedagogical practice. Sub categories are rapidly emerging, such as context-aware ubiquitous learning, that involve students learning subject content while immersed in authentic and relevant surroundings. Learning cultures are a nebulous blend of traditions, values, beliefs, and rituals built up over time. For a long time, education has long been conceived as classroom-based and predominantly sedentary (Merchant, 2012). Recent mobile technologies are disrupting this culture in favor of learning that is contextualized, personalized, on demand, and ubiquitous (Crompton, 2013). 21st century students are a different breed than past generations (Prensky, 2001). These students have grown up in a time that has not only altered their perceptions and practices but modified the wiring of the brain through neuroplasticity (Crompton, 2012). Students now cognitively receive information quickly through non-linear methods (Gross, 2003, Oblinger & Oblinger, 2005). They think differently. They also seem to be attached to mobile devices 24/7, although the content of the lesson does not match what they seem to be doing on the mobile devices. This presentation will showcase how to get your students to harness the power of mobile devices for educational purposes. For example, students in your classes will be using devices to collaborate on activities with Google Forms, crowdsourcing the best class questions in Slido, and screencasting thoughts and ideas to share with others with Educreations. These are examples of free apps or Web 2.0 tools that can be used on all the major mobile platforms. Crompton, H. (2013). Mobile learning: New approach, new theory. In Z. L. Berge & L. Y.

    2012-01-01

    The team of authors at Marshall Space Flight Center (MSFC) has been investigating estimating techniques for the vibration response of launch vehicle panels excited by acoustics and/or aero-fluctuating pressures. Validation of the approaches used to estimate these environments based on ground tests of flight like hardware is of major importance to new vehicle programs. The team at MSFC has recently expanded upon the first series of ground test cases completed in December 2010. The follow on tests recently completed are intended to illustrate differences in damping that might be expected when cable harnesses are added to the configurations under test. This validation study examines the effect on vibroacoustic response resulting from the installation of cable bundles on a curved orthogrid panel. Of interest is the level of damping provided by the installation of the cable bundles and whether this damping could be potentially leveraged in launch vehicle design. The results of this test are compared with baseline acoustic response tests without cables. Damping estimates from the measured response data are made using a new software tool that employs a finite element model (FEM) of the panel in conjunction with advanced optimization techniques. This paper will report on the \\damping trend differences. observed from response measurements for several different configurations of cable harnesses. The data should assist vibroacoustics engineers to make more informed damping assumptions when calculating vibration response estimates when using model based analysis approach. Achieving conservative estimates that have more flight like accuracy is desired. The paper may also assist analysts in determining how ground test data may relate to expected flight response levels. Empirical response estimates may also need to be adjusted if the measured response used as an input to the study came from a test article without flight like cable harnesses.

    2007-07-01

    The oil industry is turning its attention to the more complex development of heavy oil fields in order to meet the ever increasing demands of the manufacturing sector. The current thermal recovery techniques of heavy oil developments provide an opportunity to benefit from the geothermal energy created during the heavy oil production process. There is scope to improve the current recovery factors of heavy oil reservoirs, and there is a need to investigate the associated geothermal energy potential that has been historically neglected. This paper presents a new concept of harnessing the geothermal energy potential of heavy oil reservoirs with the co-production of incremental reserves. (auth)

    2005-01-01

    Full Text Available Abstract Background Africa in the twenty-first century is faced with a heavy burden of disease, combined with ill-equipped medical systems and underdeveloped technological capacity. A major challenge for the international community is to bring scientific and technological advances like genomics to bear on the health priorities of poorer countries. The New Partnership for Africa's Development has identified science and technology as a key platform for Africa's renewal. Recognizing the timeliness of this issue, the African Centre for Technology Studies and the University of Toronto Joint Centre for Bioethics co-organized a course on Genomics and Public Health Policy in Nairobi, Kenya, the first of a series of similar courses to take place in the developing world. This article presents the findings and recommendations that emerged from this process, recommendations which suggest that a regional approach to developing sound science and technology policies is the key to harnessing genome-related biotechnology to improve health and contribute to human development in Africa. Methods The objectives of the course were to familiarize participants with the current status and implications of genomics for health in Africa; to provide frameworks for analyzing and debating the policy and ethical questions; and to begin developing a network across different sectors by sharing perspectives and building relationships. To achieve these goals the course brought together a diverse group of stakeholders from academic research centres, the media, non-governmental, voluntary and legal organizations to stimulate multi-sectoral debate around issues of policy. Topics included scientific advances in genomics innovation systems and business models, international regulatory frameworks, as well as ethical and legal issues. Results Seven main recommendations emerged: establish a network for sustained dialogue among participants; identify champions among politicians; use the

  10. Harness That S.O.B.: Distributing Remote Sensing Analysis in a Small Office/Business

    2009-12-01

    Researchers in a small office/business (SOB) operate with limited funding, equipment, and software availability. To mitigate these issues, we developed a distributed computing framework that: 1) leverages open source software to implement functionality otherwise reliant on proprietary software and 2) harnesses the unused power of (semi-)idle office computers with mixed operating systems (OSes). This abstract outlines some reasons for the effort, its conceptual basis and implementation, and provides brief speedup results. The Multiple-Endmember Linear Spectral Unmixing Model (MELSUM)1 processes remote-sensing (hyper-)spectral images. The algorithm is computationally expensive, sometimes taking a full week or more for a 1 million pixel/100 wavelength image. Analysis of pixels is independent, so a large benefit can be gained from parallel processing techniques. Job concurrency is limited by the number of active processing units. MELSUM was originally written in the Interactive Data Language (IDL). Despite its multi-threading capabilities, an IDL instance executes on a single machine, and so concurrency is limited by the machine's number of central processing units (CPUs). Network distribution can access more CPUs to provide a greater speedup, while also taking advantage of (often) underutilized extant equipment. appropriately integrating open source software magnifies the impact by avoiding the purchase of additional licenses. Our method of distribution breaks into four conceptual parts: 1) the top- or task-level user interface; 2) a mid-level program that manages hosts and jobs, called the distribution server; 3) a low-level executable for individual pixel calculations; and 4) a control program to synchronize sequential sub-tasks. Each part is a separate OS process, passing information via shell commands and/or temporary files. While the control and low-level executables are short-lived, the top-level program and distribution server run (at least) for the entirety of

    Şoimoşan, Teodora M.; Danku, Gelu; Felseghi, Raluca A.

    2017-12-01

    Within the thermo-energy optimization process of an existing heating system, the increase of the system's energy efficiency and speeding-up the transition to green energy use are pursued. The concept of multi-energy district heating system, with high harnessing levels of the renewable energy sources (RES) in order to produce heat, is expected to be the key-element in the future urban energy infrastructure, due to the important role it can have in the strategies of optimizing and decarbonizing the existing district heating systems. The issues that arise are related to the efficient integration of different technologies of harnessing renewable energy sources in the energy mix and to the increase of the participation levels of RES, respectively. For the holistic modeling of the district heating system, the concept of the energy hub was used, where the synergy of different primary forms of entered energy provides the system a high degree energy security and flexibility in operation. The optimization of energy flows within the energy hub allows the optimization of the thermo-energy district system in order to approach the dual concept of smart city & smart energy.

    Seventeen healthy volunteers were subjected to right and left lateral impacts 5.0, 6.8, 9.2, and 16.8 m/s acceleration while positioned in a Volvo car seat with lap and shoulder seat belt restraint in laboratory setting. The purpose of this study was to determine the effect of using a standard 3-point lap and shoulder seat belt and Volvo car seat on the response of the cervical muscles to increasing low-velocity lateral impacts. A previous study of lateral impacts in a 5-point harness restraint with head and trunk in neutral posture suggests that the burden of impact is borne primarily by the splenius capitis muscle contralateral to the direction of impact. That study, however, used a nonstandard harness for automobiles, and other studies suggest that a lap-and-shoulder seat belt may increase the risk of whiplash injury. Triaxial accelerometers recorded the acceleration of the 1) sled, 2) torso at the shoulder level, and 3) head of the participant, while bilateral electromyograms of the sternocleidomastoids, trapezii, and splenii capitis were also recorded. For participants experiencing a right or left lateral impact, the muscle responses increased with increasing levels of acceleration (P trend to progressively decrease with increasing levels of acceleration. The peak head accelerations relative to the sled ranged from 2.5 to 10.6 m/s. When the impact was a right lateral impact, at the highest sled acceleration, the left splenius capitis generated 47% of its maximal voluntary contraction (MVC), and the left trapezius also 46% of its MVC; the left and right sternocleidomastoid, right splenius capitis, and right trapezius generated 29% or less of their MVC. For the highest level of acceleration in a left lateral impact, the right splenius capitis generated 48% of its MVC and the right trapezius 57% of the MVC, the left and right sternocleidomastoid, left splenius capitis, and left trapezius generated 29% or less of their MVC. In both directions of impact, the

    We have reviewed whether the complications of obesity can be attributed to low levels of physical activity and fitness, or if fatness per se has adverse effects on health. In both observational and interventional studies, fatness and inactivity seem to be independent risk factors. Abdominal obesity...... is a predictor of cardiovascular disease, which is independent of low fitness level, and obesity affects other risk factors adversely than inactivity does. However, physical activity does reduce the risk of type 2 diabetes and heart disease. It is concluded that both inactivity and obesity have an adverse effect...

  7. [Social marketers' lack of success in using CSM discipline to harness commercial resources and increase contraceptive prevalence].

    Science.gov (United States)

    Davies, J

    1984-01-01

    Social marketers have certainly shown that the CSM discipline can quickly and cost-effectively harness commercial resources to increase contraceptive prevalence. But why hasn't the social marketing idea caught on in more countries? According to Social Marketing Forum, only a tiny number of countries have active programs after more than a decade of effort. The most likely reason for this lack of success is doubt and fear on the part of both developing countries' officials and donor agencies about allowing marketing enthusiasts--with our very noticeable advertising methods--to join the family planning fight. And what has our answer been? Usually, a head-on retort such as, "But look at all the condoms we've sold]" And that gets us nowhere, because the successful peddling of 1 not-so-impressive method doesn't begin to balance the fears of a possible backlash that brash condom promotions could bring down on official heads. The lesson we should be learning is that social marketers possess to narrow an outlook and promote a small range of products that don't enthuse decisionmakers. Hence, we are often perceived as condom salesmen--and not much more. What should we be doing? We should be selling the idea of using private sector experience to assist national development. That means social development, particularly improved health, family planning and women's education. These 3 activities have proven effective in reducing fertility and would add up to a marketing opportunity--a longterm challenge that should enthuse dicisionmakers, private sector entrepreneurs and donor agencies alike. Further, our model--the commercial sector--is renowned for branching out and secceeding in a broad range of endeavors. As an example, Procter and Gamble uses separate divisions to market different products. Initiatives already exist in many countries to harness the private sector as a development tool. Social marketers should be leading the initiative--and benefitting from it, too. full text

  8. Microbes at Surface-Air Interfaces: The Metabolic Harnessing of Relative Humidity, Surface Hygroscopicity, and Oligotrophy for Resilience

    The human environment is predominantly not aqueous, and microbes are ubiquitous at the surface-air interfaces with which we interact. Yet microbial studies at surface-air interfaces are largely survival-oriented, whilst microbial metabolism has overwhelmingly been investigated from the perspective of liquid saturation. This study explored microbial survival and metabolism under desiccation, particularly the influence of relative humidity (RH), surface hygroscopicity, and nutrient availability on the interchange between these two phenomena. The combination of a hygroscopic matrix (i.e., clay or 4,000 MW polyethylene glycol) and high RH resulted in persistent measurable microbial metabolism during desiccation. In contrast, no microbial metabolism was detected at (a) hygroscopic interfaces at low RH, and (b) less hygroscopic interfaces (i.e., sand and plastic/glass) at high or low RH. Cell survival was conversely inhibited at high RH and promoted at low RH, irrespective of surface hygroscopicity. Based on this demonstration of metabolic persistence and survival inhibition at high RH, it was proposed that biofilm metabolic rates might inversely influence whole-biofilm resilience, with ‘resilience’ defined in this study as a biofilm’s capacity to recover from desiccation. The concept of whole-biofilm resilience being promoted by oligotrophy was supported in desiccation-tolerant Arthrobacter spp. biofilms, but not in desiccation-sensitive Pseudomonas aeruginosa biofilms. The ability of microbes to interact with surfaces to harness water vapor during desiccation was demonstrated, and potentially to harness oligotrophy (the most ubiquitous natural condition facing microbes) for adaptation to desiccation.

    Issues in reconfigurability and adaptability in heterogeneous distributed systems for high-performance computing are the focus of the work funded by this grant. Our efforts are part of an ongoing research project in metacomputing and are a follow on to the DOE funded PVM system that has witnessed over a decade of use at numerous institutions worldwide. The current project, termed Harness, investigates novel methodologies and tools for distributed metacomputing, focusing on dynamically reconfigurable software frameworks. During the first phase, we defined the metacomputing architecture embodied in Harness and developed prototype subsystems as proof of concept exercises. Subsequently, we designed and developed a complete software framework manifesting the Harness architecture, and also developed several tools and subsystems that demonstrated the viability and effectiveness of our proposed model for next generation metacomputing. We then used this substrate to emulate multiple programming environments on Harness, and conducted performance evaluation and tuning exercises. The main research results from these efforts include the establishment of software metacomputing systems as viable and cost-effective alternatives to MPPs; the demonstration of dynamic and reconfigurable platforms as effective methods of tailoring parallel computing environments; the development of methodologies to construct plugin modules for component-based distributed systems; contributions to performance modeling and optimization in emulated software environments; and software architectures for multi- and mixed-paradigm parallel distributed computing. Details and specifics on these and other results have been reported in numerous publications, and are manifested in software systems, all of which may be accessed at or via the website http://www.mathcs.emory.edu/harness/

    Closed reduction and spica casting is the most commonly recommended choice for infants with developmental dysplasia of the hip (DDH) for whom Pavlik harness treatment has failed, but it requires general anesthesia in addition to the challenges of spica cast care. The purposes of this study were to evaluate the effectiveness of Ilfeld bracing for infants for whom Pavlik harness treatment is unsuccessful and to compare these results with those for a similar cohort of patients directly undergoing closed reduction and spica casting. We reviewed the cases of a consecutive series of children with DDH who had failure of Pavlik harness treatment and were subsequently managed with Ilfeld bracing (the BR cohort) and compared this cohort with a similar historical group of infants who had failure of Pavlik harness treatment but had standard closed reduction and spica casting (the CR cohort). The cohorts were compared with respect to clinical and ultrasonographic data at the time of Pavlik discontinuation. At one year, the hip stability and acetabular index were assessed; the presence of osteonecrosis was graded according to the criteria described by Salter et al. Twenty-eight hips (nineteen infants) made up the BR cohort and twenty-two hips (sixteen infants) made up the CR cohort. Ultrasonographic indices (including the alpha angle and the percentage of femoral head coverage) were comparable between the two cohorts (p=0.66 and 0.19, respectively). Following treatment, a stable reduction was achieved in twenty-three (82%) of twenty-eight hips in the BR cohort compared with twenty (91%) of twenty-two hips in the CR cohort. At one year, acetabular indices were similar between both cohorts (mean and standard deviation, 27°±6° for the BR cohort versus 27°±5° for the CR cohort; p=0.62); however, osteonecrosis developed in three hips in the CR cohort compared with none in the BR cohort. In our series of infants with DDH for whom Pavlik harness treatment had failed, Ilfeld

    2018-04-01

    With an ever more competitive global labour market, coupled with an ever-increasing population of PhD-qualified graduates, the ability to communicate effectively and build strategic connections with others can be advantageous in the job-search process. Whether in pursuit of a tenure-track or non-academic position, many postdoctoral researchers and PhD students will benefit from networking as early as possible to enhance their career prospects. Sometimes viewed cynically as 'using people' or dismissed as 'the old boy network,' the ability to make meaningful connections and build relationships can be more valuable than other job-related skills in order to gain entry to, and progress within, many professions. This mini-review highlights the positive influence of networking and how bioscience PhD students and postdoctoral researchers can harness the power of communities to achieve career success. It is argued that those who make connections and promote personal patronage through networking can gain an advantage over their contemporaries. A summary of key theories and research studies that underpin the practice of networking provides credence to these assertions, which are further substantiated with examples pertinent to the academic community. Although primarily focussed on the biosciences, much of the content is applicable to other scientists at a similar career stage.

    Full Text Available Furniture is a major export commodity in Indonesia with a total value of USD 1.96 million in 2007.  Jepara District is one of the key location for wood furniture production with 15,271 furniture related business units employing 176,469 workers.  However, inefficiencies and power imbalances throughout the furniture value chain have resulted in overharvesting and uneven distribution of gains among the industry’s actors.  In contrast to price-setting international furniture retailers, small-scale producers enjoy the least value from their products.  In order to increase added value and competitiveness, small-scale furniture producers have made efforts to upgrade by harnessing their social network and institutions.  This paper describes small-scale furniture producers’ efforts to upgrade by utilising their social network and institutions in Jepara.  Data was collected through in-depth interviews with members of the small-scale furniture producers’ association.  The research provides insight into the nature of social networks and information flow and develops future scenarios to upgrade.  The scenarios will not only benefit the furniture industry in Jepara, but may also be adopted for similar industries throughout Indonesia and the world, and potentially improve many people’s economies and livelihoods.Keywords: wood-based industry, furniture, small-scale, social network, institution

  1. Harnessing the private health sector by using prices as a policy instrument: Lessons learned from South Africa.

    2018-05-01

    Governments frequently draw upon the private health care sector to promote sustainability, optimal use of resources, and increased choice. In doing so, policy-makers face the challenge of harnessing resources while grappling with the market failures and equity concerns associated with private financing of health care. The growth of the private health sector in South Africa has fundamentally changed the structure of health care delivery. A mutually reinforcing ecosystem of private health insurers, private hospitals and specialists has grown to account for almost half of the country's spending on health care, despite only serving 16% of the population with the capacity to pay. Following years of consolidation among private hospital groups and insurance schemes, and after successive failures at establishing credible price benchmarks, South Africa's private hospitals charge prices comparable with countries that are considerably richer. This compromises the affordability of a broad-based expansion in health care for the population. The South African example demonstrates that prices can be part of a structure that perpetuates inequalities in access to health care resources. The lesson for other countries is the importance of norms and institutions that uphold price schedules in high-income countries. Efforts to compromise or liberalize price setting should be undertaken with a healthy degree of caution. Copyright © 2018 Elsevier B.V. All rights reserved.

  2. An isotropic suspension system for a biaxial accelerometer using electroplated thick metal with a HAR SU-8 mold

    Lee, Jin Seung; Lee, Seung S

    2008-01-01

    In this paper, a novel approach is developed to design an isotropic suspension system using thick metal freestanding micro-structures combining bulk micro-machining with electroplating based on a HAR SU-8 mold. An omega-shape isotropic suspension system composed of circular curved beams that have free switching of imaginary boundary conditions is proposed. This novel isotropic suspension design is not affected by geometric dimensional parameters and always achieves matching stiffness along the principle axes of elasticity. Using the finite element method, the isotropic suspension system was compared with an S-shaped meandering suspension system. In order to realize the suggested isotropic suspension system, a cost-effective fabrication process using electroplating with the SU-8 mold was developed to avoid expensive equipment and materials such as deep reactive-ion etching (DRIE) or a silicon-on-insulator (SOI) wafer. The fabricated isotropic suspension system was verified by electromagnetic actuation experiments. Finally, a biaxial accelerometer with isotropic suspension system was realized and tested using a vibration generator system. The proposed isotropic suspension system and the modified surface micro-machining technique based on electroplating with an SU-8 mold can contribute towards minimizing the system size, simplifying the system configuration, reducing the system price of and facilitating mass production of various types of low-cost sensors and actuators

  3. Harnessing mode-selective nonlinear optics for on-chip multi-channel all-optical signal processing

    Directory of Open Access Journals (Sweden)

    2016-11-01

    Full Text Available All-optical signal processing based on nonlinear optical effects allows for the realization of important functions in telecommunications including wavelength conversion, optical multiplexing/demultiplexing, Fourier transformation, and regeneration, amongst others, on ultrafast time scales to support high data rate transmission. In integrated photonic subsystems, the majority of all-optical signal processing systems demonstrated to date typically process only a single channel at a time or perform a single processing function, which imposes a serious limitation on the functionality of integrated solutions. Here, we demonstrate how nonlinear optical effects can be harnessed in a mode-selective manner to perform simultaneous multi-channel (two and multi-functional optical signal processing (i.e., regenerative wavelength conversion in an integrated silicon photonic device. This approach, which can be scaled to a higher number of channels, opens up a new degree of freedom for performing a broad range of multi-channel nonlinear optical signal processing functions using a single integrated photonic device.

    2011-09-01

    Charles Darwin hoped that a large body of working naturalists would embrace evolution after the Origin of Species appeared in late 1859. He was disappointed. His evolutionary ideas at first made painfully little progress in the scientific community. But by 1863 the tide had turned dramatically, and within five years evolution became scientific orthodoxy in Britain. The Origin's reception followed this peculiar trajectory because Darwin had not initially tied its theory to productive original scientific investigation, which left him vulnerable to charges of reckless speculation. The debate changed with his successful application of evolution to original problems, most notably orchid fertilization, the subject of a well-received book in 1862. Most of Darwin's colleagues found the argument of the Origin convincing when they realized that it functioned productively in the day-to-day work of science-and not before. The conceptual force of the Origin, however outwardly persuasive, acquired full scientific legitimacy only when placed "in the harness of daily labour".

    An area offshore of Sandy Hook, New Jersey, has been used extensively for disposal of dredged and other materials, derived from the New York/New Jersey Harbor and surrounding areas, since the late 1800's (Figure 1). Between 1976 and 1995, the New York Bight Dredged Material Disposal Site, also known as the Mud Dump Site (Figure 2), received on average about 6 million cubic yards of material each year from federal and private maintenance dredging and from harbor deepening activities (Massa and others, 1996). In September 1997 the Mud Dump Site (MDS) was closed as an official ocean disposal site by the U.S. Environmental Protection Agency (http://www.epa.gov/), and the MDS and surrounding areas were designated as the Historic Area Remediation Site (HARS). The HARS is subdivided into a Primary Remediation Area (PRA, subdivided into 9 cells), a Buffer Zone, and a No-Discharge Zone (Figure 2). The sea floor of the HARS, approximately 9 square nautical miles in area, is being remediated by placing at least a one-meter cap of Category I (clean) dredged material on top of the existing surface sediments that exhibit varying degrees of degradation. (See http://www.nan.usace.army.mil/business/prjlinks/dmmp/benefic/hars.htm)(Category I sediments have no potential short or long-term impacts and are acceptable for unrestricted ocean disposal (EPA, 1996)). About 1.1 million cubic yards of dredged material for remediation was placed in the HARS in 1999, and 2.5 million cubic yards in 2000. Three multibeam echosounder surveys were carried out to map the topography and surficial geology of the HARS. The surveys were conducted November 23 - December 3, 1996, October 26 - November 11, 1998, and April 6 - 30, 2000. The surveys were carried out as part of a larger survey of the Hudson Shelf Valley and adjacent shelf (Butman and others, 1998, (http://pubs.usgs.gov/openfile/of98-616/).

    2012-01-01

    Novel methods, such as Internet-based interventions, are needed to combat the spread of HIV. While past initiatives have used the Internet to promote HIV prevention, the growing popularity, decreasing digital divide, and multi-functionality of social networking sites, such as Facebook, make this an ideal time to develop innovative ways to use online social networking sites to scale HIV prevention interventions among high-risk groups. The UCLA Harnessing Online Peer Education study is a longitudinal experimental study to evaluate the feasibility, acceptability, and preliminary effectiveness of using social media for peer-led HIV prevention, specifically among African American and Latino Men who have Sex with Men (MSM). No curriculum currently exists to train peer leaders in delivering culturally aware HIV prevention messages using social media. Training was created that adapted the Community Popular Opinion Leader (C-POL) model, for use on social networking sites. Peer leaders are recruited who represent the target population and have experience with both social media and community outreach. The curriculum contains the following elements: discussion and role playing exercises to integrate basic knowledge of HIV/AIDS, awareness of sociocultural HIV/AIDS issues in the age of technology, and communication methods for training peer leaders in effective, interactive social media-based HIV prevention. Ethical issues related to Facebook and health interventions are integrated throughout the sessions. Training outcomes have been developed for long-term assessment of retention and efficacy. This is the first C-POL curriculum that has been adapted for use on social networking websites. Although this curriculum has been used to target African-American and Latino MSM, it has been created to allow generalization to other high-risk groups.

    NASA's Human Research Program (HRP) and Space Life Sciences Directorate (SLSD), not unlike many NASA organizations today, struggle with the inherent inefficiencies caused by dependencies on heterogeneous data systems and silos of data and information spread across decentralized discipline domains. The capture of operational and research-based data/information (both in-flight and ground-based) in disparate IT systems impedes the extent to which that data/information can be efficiently and securely shared, analyzed, and enriched into knowledge that directly and more rapidly supports HRP's research-focused human system risk mitigation efforts and SLSD s operationally oriented risk management efforts. As a result, an integrated effort is underway to more fully understand and document how specific sets of risk-related data/information are generated and used and in what IT systems that data/information currently resides. By mapping the risk-related data flow from raw data to useable information and knowledge (think of it as the data supply chain), HRP and SLSD are building an information architecture plan to leverage their existing, shared IT infrastructure. In addition, it is important to create a centralized structured tool to represent risks including attributes such as likelihood, consequence, contributing factors, and the evidence supporting the information in all these fields. Representing the risks in this way enables reasoning about the risks, e.g. revisiting a risk assessment when a mitigation strategy is unavailable, updating a risk assessment when new information becomes available, etc. Such a system also provides a concise way to communicate the risks both within the organization as well as with collaborators. Understanding and, hence, harnessing the human system risk-related data supply chain enhances both organizations' abilities to securely collect, integrate, and share data assets that improve human system research and operations.

    Potential impacts of inevitable leaks of silver nanoparticles (AgNPs) into environment on human beings need attention. Owing to the vitality of photosynthesis in maintaining life and ecosystem functioning, impacts of exogenously applied nanoparticulate and Ag + on photosystem (PS)II function, which governs overall photosynthesis, in wheat and sunflower were evaluated. PSII efficiency and related Chl a fluorescence kinetics of these two plants remained unaffected by AgNPs. However, Ag + caused a significant decline in the PSII activity and related fluorescence steps in wheat, but not in sunflower. Electron flow between Q A and PQ pool was found most sensitive to Ag + . Number of active reaction centers, electron transport, trapping of absorbed light for photochemistry, and performance index declined, while dissipation of absorbed light energy as heat significantly increased in wheat exposed to Ag + . Total antioxidant activity in sunflower was least affected by both Ag and AgNPs. In contrast, in the case of wheat, the antioxidant activity was declined by Ag + but not by AgNPs. Further, the amount of silver absorbed by plants exposed to Ag + was higher than that absorbed by plants exposed to AgNPs. While wheat retained majority of Ag in its roots, sunflower showed major Ag accumulation in stem. Photosynthetic events in sunflower, unlike wheat, were least affected as no detectable Ag levels was recorded in their leaves. Our findings revealed that AgNPs seemed non/less-toxic to light harnessing photosynthetic machinery of wheat, compared to Ag + . Photosynthetic events in sunflower were not affected by Ag + , either, as its translocation to leaves was restricted. Copyright © 2017. Published by Elsevier Ltd.

    Monitoring the levels of pollutants in ambient air has long been the responsibility of environmental agencies, and traditional programs have relied on a relatively small number of fixed stations that are expensive to install and operate. The spatial coverage of pollutant data ranges from limited in many urban areas to very sparse in smaller suburban and rural areas. Increasingly, the latter are being affected by new pollutant sources such as backyard drilling systems for energy development, and concentrated animal feeding operations and biodiesel production facilities on former agricultural lands. Regional measurement stations are not able to inform local communities about the types and concentrations of pollutants in their ambient and indoor air. Meanwhile, epidemiology studies and clinical data continue to indicate a link between air pollutants and adverse health effects, including respiratory and cardiovascular disease. With asthma on the rise and heart disease among the leading killers, the public has become increasingly concerned about knowing what their personal exposure levels are so they can determine appropriate measures to protect their health. To address this long-standing need, the U.S. Environmental Protection Agency (EPA) has embarked upon an innovative program to improve the understanding of air pollution at the community and neighborhood scales. This program harnesses striking advances in sensor technology, mobile applications, and environmental informatics, with citizens playing a key role. The goal is to facilitate the development and widespread use of inexpensive mobile sensors, for widespread collection and integration of air quality data by citizens across the nation (and world), to help guide environmental health protection programs.

  20. Mad, terroir og tv: Smag på Danmark!

    2008-09-01

    Full Text Available Mad fylder mere i medierne, men hvordan underholder fx et madprogram på tv? Med afsæt i de 13 afsnit af Claus Meyer-serien Smag på Danmark! undersøger vi, hvordan serien er konstrueret og fortalt. Især ser vi på, hvilken rolle de 13 forskellige steder, som serien foregår på, har. Vi diskuterer begreber som terroir og mytologisering. Serien etablerer dobbeltheder og relationer, og i tråd med dette forlenes sted som terroir både med al og med ingen betydning. Mad knyttes som et tegn, med Barthes in mente, til stedet, men på en måde, der leverer rum for seerens eget forestillingsarbejde. Serien demonstrerer for seerne, hvordan smagsdomme kan foregå med Meyer som seerens stedfortræder i et ferie- og fritidsunivers. Den nydelse, som serien konstant etablerer, demonstrerer og anticiperer, kan seeren deltage i med sit eget fantasiarbejde: Det er god underholdning, fordi så meget er overladt til seernes forestillingsarbejde. Food, Terroir, and Television: Taste Denmark! Food has become more dominant in the media landscape, but how does a food programme on television entertain us? We analyse how the 13 episodes of the Claus Meyer series Smag på Danmark (Taste Denmark!are constructed and narrated. We pay particular attention to the different locations of the episodes and discuss the terms terroir and mythologization. The series establishes ambiguities and relations, and in this connection the location understood as terroir means everything – and at the same time means nothing at all. With reference to Barthes, the series links food as a sign to location, but in such a way that room is left for the viewer’s own imagination. The series demonstrates to the viewers how judgements of taste can be made in a time of leisure and a universe of holidays, with Meyer acting as the viewer’s proxy. The series is constantly establishing, demonstrating and anticipating a pleasure in which the viewer can participate in his or her own imagination

  10. Harnessing a methane-fueled, sediment-free mixed microbial community for utilization of distributed sources of natural gas.

    Marlow, Jeffrey J; Kumar, Amit; Enalls, Brandon C; Reynard, Linda M; Tuross, Noreen; Stephanopoulos, Gregory; Girguis, Peter

    2018-06-01

    Harnessing the metabolic potential of uncultured microbial communities is a compelling opportunity for the biotechnology industry, an approach that would vastly expand the portfolio of usable feedstocks. Methane is particularly promising because it is abundant and energy-rich, yet the most efficient methane-activating metabolic pathways involve mixed communities of anaerobic methanotrophic archaea and sulfate reducing bacteria. These communities oxidize methane at high catabolic efficiency and produce chemically reduced by-products at a comparable rate and in near-stoichiometric proportion to methane consumption. These reduced compounds can be used for feedstock and downstream chemical production, and at the production rates observed in situ they are an appealing, cost-effective prospect. Notably, the microbial constituents responsible for this bioconversion are most prominent in select deep-sea sediments, and while they can be kept active at surface pressures, they have not yet been cultured in the lab. In an industrial capacity, deep-sea sediments could be periodically recovered and replenished, but the associated technical challenges and substantial costs make this an untenable approach for full-scale operations. In this study, we present a novel method for incorporating methanotrophic communities into bioindustrial processes through abstraction onto low mass, easily transportable carbon cloth artificial substrates. Using Gulf of Mexico methane seep sediment as inoculum, optimal physicochemical parameters were established for methane-oxidizing, sulfide-generating mesocosm incubations. Metabolic activity required >∼40% seawater salinity, peaking at 100% salinity and 35 °C. Microbial communities were successfully transferred to a carbon cloth substrate, and rates of methane-dependent sulfide production increased more than threefold per unit volume. Phylogenetic analyses indicated that carbon cloth-based communities were substantially streamlined and were

    Muñoz, Rodrigo C., Jr.; Manansala, Chad Deo G.

    2018-01-01

    This study is based on the potential of thermoelectric coupling such as the thermoelectric cooler module. A thermoelectric cooler converts the heat coming from the cook stove into electricity and store in a battery. A dc-dc boost converter will be used to produce enough voltage to light a minimum house dwelling or charge phone battery. This device will be helpful to those that faces a problem on electricity especially in the isolated areas. The study aims (1) to harness heat from the cook stove up to 110 °C (2) To automatically cool-off the system to protect the thermoelectric cooler from damage due to excessive heat using an electronic solenoid; (3) To store energy harnessed in the battery; (4) To amplify the output voltages of the battery using DC to DC boost converter for lighting system and charging of mobile phone battery. From various tests conducted, it can fully charge a mobile phone in 3 hours observing the unit’s battery voltage drop from 4.06V to 3.98V. In the testing it used different orientation of steel rod by conduction to transfer heat and by radiation through tubular steel with its different dimensions. Most recent testing proved that the 2x2x9 tubular steel by radiation had the best result. The temperature reached more than a hundred degree Celsius that met the objective. The test resulted of boosting the voltage of the battery output from 3.7V to 4.96V on the average. The boosted voltage decrease as the system’s cool-off mechanism operated when the temperature reached above 110 degree Celsius decreasing output voltage to 0.8V resulting the boosted voltage to drop to zero. Therefore, the proponents concluded that heat waste can be converted to electrical energy by harnessing heat through radiation, with the help of TEC that generates voltage for lighting and can be boosted to be used for mobile charging. Furthermore, the study proved that the excess heat can damaged the TEC which was prevented by using of cooling-off mechanism, making it more

    An integrated probabilistic approach has been developed to assess composites for high temperature applications. This approach was used to determine thermal and mechanical properties and their probabilistic distributions of a 5-harness 0/90 Sylramic fiber/CVI-SiC/Mi-SiC woven Ceramic Matrix Composite (CMC) at high temperatures. The purpose of developing this approach was to generate quantitative probabilistic information on this CMC to help complete the evaluation for its potential application for HSCT combustor liner. This approach quantified the influences of uncertainties inherent in constituent properties called primitive variables on selected key response variables of the CMC at 2200 F. The quantitative information is presented in the form of Cumulative Density Functions (CDFs). Probability Density Functions (PDFS) and primitive variable sensitivities on response. Results indicate that the scatters in response variables were reduced by 30-50% when the uncertainties in the primitive variables, which showed the most influence, were reduced by 50%.

    2018-05-10

    Harnessing the genomics big data requires innovation in how we extract and interpret biologically relevant variants. Currently, there is no established catalog of prioritized missense variants associated with deleterious protein function phenotypes. We report in this study, to the best of our knowledge, the first genome-wide prioritization of sequence variants with the most deleterious effect on protein function (potentially deleterious variants [pDelVars]) in nine vertebrate species: human, cattle, horse, sheep, pig, dog, rat, mouse, and zebrafish. The analysis was conducted using the Ensembl/BioMart tool. Genes comprising pDelVars in the highest number of examined species were identified using a Python script. Multiple genomic alignments of the selected genes were built to identify interspecies orthologous potentially deleterious variants, which we defined as the "ortho-pDelVars." Genome-wide prioritization revealed that in humans, 0.12% of the known variants are predicted to be deleterious. In seven out of nine examined vertebrate species, the genes encoding the multiple PDZ domain crumbs cell polarity complex component (MPDZ) and the transforming acidic coiled-coil containing protein 2 (TACC2) comprise pDelVars. Five interspecies ortho-pDelVars were identified in three genes. These findings offer new ways to harness genomics big data by facilitating the identification of functional polymorphisms in humans and animal models and thus provide a future basis for optimization of protocols for whole genome prioritization of pDelVars and screening of orthologous sequence variants. The approach presented here can inform various postgenomic applications such as personalized medicine and multiomics study of health interventions (iatromics).

  12. Multiple Sclerosis and the LIF/IL-6 Axis: Use of Nanotechnology to Harness the Tolerogenic and Reparative Properties of LIF

    Directory of Open Access Journals (Sweden)

    Su M. Metcalfe

    2015-05-01

    Full Text Available Leukaemia inhibitory factor (LIF plays a critical role in “stemness” versus “differentiation”, a property that underpins the core value of LIF as a therapeutic for both the treatment of autoimmune disease and for promoting tissue repair. This value can be realized using nano-engineering technology, where a new generation of tools can, with unprecedented ability, manipulate biological functions. One striking example is the treatment of multiple sclerosis (MS. The underpinning biology is the newly identified LIF/IL-6 axis in T lymphocytes, which can tilt the behaviour between immune tolerance versus immune attack. This LIF/IL-6 axis is ideally suited to nanotherapeutic manipulation, given its inherent mechanistic simplicity of two mutually opposing feed-forward loops that determine either tolerogenic (LIF or inflammatory (IL-6 immunity. Using LIF that is formulated in biodegradable nanoparticles (LIF-NP and targeted to CD4+ T cells, the axis is harnessed towards immune tolerance. This has implications for the treatment of autoimmune diseases, where the clinical burden is immense. It encompasses more than 100 diseases and, in the USA alone, costs more than $100 billion in direct health care costs annually. Other properties of LIF include the promotion of healthy neuro-glial interactions within the central nervous system (CNS, where, in addition to MS, LIF-NP therapy is relevant to inflammatory neurodegenerative diseases that represent a large and increasing need within aging populations. Thirdly, LIF is a reparative growth factor that can maintain genomic plasticity. LIF-NP supports the use of stem cell-based therapies in regenerative medicine plus augment therapeutic benefits within the patient. These core properties of LIF are greatly amplified in value by the advantage of being formulated as nanoparticles, namely (i targeted delivery, (ii exploitation of endogenous regulatory pathways and (iii creation of surrogate micro-stromal niches

    Sinclair, Wendy; McLoughlin, Moira; Warne, Tony

    2015-11-01

    This paper explores some of the difficulties, challenges and rewards for student nurses and nurse academics when harnessing social media (SoMe) as part of the overall learning experience. The paper draws upon data in the form of student voices, captured through an online planned Twitter chat. This data analysis provides the basis of a case study on the student experience in practice placements. A planned 1 h Twitter chat took place in June 2013, specifically aimed at student nurses. What transpired was an illuminating debate, eliciting responses from around the globe about learning in practice, mentors, and student support that lasted over 3 h. More importantly, the Twitter chat also included qualified nurses and mentors, listening and responding in real time, offering thoughts and solutions to how support and mentoring could be improved. This was in contrast to how students, locally, currently use a paper based questionnaire to give feedback in isolation. The authenticity of this feedback is often compromised by university link lecturers' who often provide a more sanitised version of this feedback to clinical placement. This paper explores whether it is possible to facilitate a realignment and capture the zeitgeist in order to provide the opportunity for enhancing learning in practice. Copyright © 2015 Elsevier Ltd.

Artikkelen problematiserer de ekstra krevende arbeidsbetingelsene som disse nye lærerne møtte i sitt første år, da de ble satt til å undervise i skolefag de ikke hadde studert. Forskningsspørsmålet er: Hvordan fremstiller nyutdannede ungdomsskolelærere sine opplevelser med å undervise i skolefag de ikke selv er formelt kvalifisert i, og på hvilke måter kan veiledning bidra med støtte? Artikkelen presenterer utdrag fra veiledningssamtaler som eksemplifiserer to nye læreres fremstilling av eget arbeid med elevvurdering når de mangler formell kvalifikasjon i faget. De nyutdannedes perspektiv, og mentorens, fremheves som et samspill gjennom inter­aksjonsanalyse. Artikkelens teoretiske bidrag er analysebegrepene – «psykologisk-emosjonell mentorstøtte» og «faglig-profesjonell mentorstøtte» – som brukes for å identifisere ulike varianter av mentorstøtte i veiledningssamtaler. Innenfor hovedtypen «faglig-profesjonell mentorstøtte» utdypes distinksjonen videre når det skilles analytisk mellom mentor-bidrag som vektlegger spisset drøfting av skolefag (faglig og mentor-innspill av pedagogisk eller mer generell didaktisk karakter (profesjonell. Dermed bidrar studien til å vise hvordan ulike kvaliteter i faglig-profesjonell lærerveiledning kan gjenkjennes i praksis. Funnene viser hvor avgjørende det er at mentor har kompetanse i det skolefaget det skal veiledes i, såfremt skoler ønsker å tilby nyutdannede lærere spisset veiledning i skolefag.

    Full Text Available UiT Norges arktiske universitet har gjennomført en nasjonal pilot i grunnskolelærerutdanning på masternivå, hvor de første studentene fullførte utdanningen og leverte masteroppgave våren 2015. Denne artikkelen fokuserer på hvilken relevans studentene opplever at masteroppgaven har for den fremtidige profesjonsutøvelsen deres. Å undersøke studentenes oppfatning av masterarbeidet er av betydning, ikke bare fordi masterutdanning blir en nasjonal ordning fra 2017, men også for å utvikle kunnskap om betydningen av forsknings- og utviklingskompetanse for grunnskolelærere. Studiens empiriske materiale er en intervjuundersøkelse med 22 av de 61 første masterstudentene. Undersøkelsen inngår i en longitudinell studie som vil belyse nyutdannedes profesjonslæring i starten av karrieren, og konkret hvordan lærere integrerer kunnskapen fra utdanningen med kunnskap og erfaringer de utvikler som ferske lærere. Resultatene fra denne delstudien viser at masterarbeidet har gitt studentene dybdekunnskap og FoU-kompetanse som er av betydning for den videre profesjonsutøvelsen. Studien viser også at det er betydningsfullt at masteroppgaven har forankring i skolens praksis og bidrar til utviklingen som lærer. Av materialet fremgår det også at studentene fremhever selvstendighet og evne til samarbeid, og de er stolte av masterarbeidet sitt. Resultatene er drøftet opp mot begrepene konseptuell og kontekstuell kunnskap (Afdal & Nerland, 2012; Muller, 2009 og i lys av profesjonsteori. Masterarbeidet synes avgjørende for profesjonsidentiteten, men det vil kreves et systematisk utviklingsarbeid for å kunne gi masterarbeidet kvaliteter som kan støtte opp om studentenes utvikling som profesjonelle lærere. For lærerutdanningene tilsier dette at FoU-kompetanse må gis oppmerksomhet fra første dag i utdanningen.Nøkkelord: grunnskolelærerutdanning, masteroppgave, nyutdannet lærer, FoU-kunnskap, profesjonell identitet, profesjonsidentitet

  2. Human Behavior and Environmental Sustainability: promoting a pro-environmental behavior by harnessing the social, psychological and physical influences of the built environment

    Abusafieh, Shaden; Razem, Maiss

    2017-11-01

    Recently, technological advancements in the sustainable design field have allowed us to reduce the ecological impact of the built environment, to reduce consumption of non-renewable resources, to create healthy environments and in some cases may even rehabilitate the ecosystem. Nevertheless, several studies have been carried out showing that sustainable technology does not automatically lead to environmentally friendly behaviors in its users. Various environmental problems threaten environmental sustainability and many of these problems are rooted in human behavior. Unfortunately, there is a lack in studies which take into consideration the human behavior influences within a sustainable built environment. We believe that the built environment should be used to support human goals and requirements, but at the same time we should consider it as a context in which human values and behaviors are cultivated. This research aimed to help in promoting environmental sustainability by using architectural design in changing relevant human behavior toward an environmentally friendly behavior. In order to achieve this, the research adopted Environment-centered Approach to gain more acute perspective into the relationship between the physical environment and human behavior, focusing on social, psychological and physical influences of the built environment. It appears that environmental psychology's merits have high potential in changing behavior within the built environment. The research provides a systematic approach for selecting, assessing, evaluating the behaviors to be changed and the factors that determine them. Furthermore, this approach helps in choosing the best interventions that could be applied in built environment to encourage such a sustainable behavior. This study tried to construct an agenda for further researches to find particular architectural design elements and strategies that we can harness to develop a pro-environment human behavior.

  8. Harnessing science for environmental regulation

    International Nuclear Information System (INIS)

    Graham, J.D.

    1991-01-01

    An introductory chapter by Graham frames the issues to be discussed; then the following three chapters describe the formation and character of three organizations. These chapters are written by authors who have each had an active management role in the organization they are writing about: Terry F. Yosie, now at the American Petroleum Institute, who staffed the SAB (Science Advisory Board) while he was at EPA; Robert A. Neal, who headed CIIT (Chemical Industry Institute of Toxicology) before leaving for a position at Vanderbilt University; and Thomas P. Grumbly, former executive director of HEI (Health Effects Institute) now president of Clean Sites, Inc. While these chapters are well written and make a vital contribution to the overall development of the book's themes, the most valuable and enjoyable parts of the book are the succeeding five chapters, which present case studies dealing with EPA's regulatory efforts on unleaded gasoline, perchloroethylene, formaldehyde, nitrates in drinking water, and carbon monoxide. Each of these case studies, nominally historical accounts of how one or more of these (three) organizations participated in the regulatory controversy, offer insight into the broader issues of dealing with, and incorporating into regulations scientific information that has high uncertainty. One of the richest aspects of the five case studies is the extensive use of referenced interviews with identified participants from all aspects of the regulatory process. This material illuminates the motivation, emotions, and goals of the different players, helping the reader to understand their positions and other issues, such as why industry pursues, and EPA and the environmental movement appear to resist, good science; what underlies EPA's preferences for one regulatory option over another; and why scientists are histant to give yes-or-no answers in accord with the real time needs of the regulatory agency

    Guinivan, D.

    2007-06-15

    The Three Gorges hydropower plant on China's Yangtze River is the world's largest hydropower project. Alstom is supplying nearly half of the turbines and generators for the project. The Three Gorges dam was constructed for several reasons, including regulating the flow of the Yangtze River which was notorious for flooding; rendering the river navigable into the center of China; and, generating electricity. The hydropower plant is expected to create as much electricity as 18 nuclear power plants. It will provide about 10 per cent of the country's energy and replace 40 to 50 million tons of raw coal combustion annually. The width of the Three Gorges is 2.4 km. As such, the greatest challenge facing the project was its sheer size. The runners for the hydro turbine were a massive 10.6 meters in diameter with a height of 5 meters, far larger than any other Alstom had ever produced. They were manufactured in a specially constructed workshop in the south of France and transported by sea to Shanghai. Six riverboats were then used to transport the draft tube elbow to the power plant. It was noted that although the United States has the largest hydropower capacity, China is the fastest growing market, where increased electrical capacity is greatly needed. This article described how the runner of the gravity dam operates. Equipment for the right bank of the Three Gorges was specifically designed to be fish friendly. Orkot plastic bearings were used due to their excellent friction characteristics without the use of grease. The bearings are produced at the Busak and Shamban associated manufacturing company Trelleborg Sealing Systems Rotherham. They are also manufactured for the American market. 4 figs.

  20. Harnessing motivation to alleviate neglect

    Directory of Open Access Journals (Sweden)

    Charlotte eRussell

    2013-06-01

    Full Text Available The syndrome of spatial neglect results from the combination of a number of deficits in attention, with patients demonstrating both spatially lateralised and non-lateralised impairments. Previous reports have hinted that there may be a motivational component to neglect and that modulating this might alleviate some of the debilitating symptoms. Additionally, recent work on the effects of reward on attention in healthy participants has revealed improvements across a number of paradigms. As the primary deficit in neglect has been associated with attention, this evidence for reward’s effects is potentially important. However, until very recently there have been few empirical studies addressing this potential therapeutic avenue. Here we review the growing body of evidence that attentional impairments in neglect can be reduced by motivation, for example in the form of preferred music or anticipated monetary reward, and discuss the implications of this for treatments for these patients. Crucially these effects of positive motivation are not observed in all patients with neglect, suggesting that the consequences of motivation may relate to individual lesion anatomy. Given the key role of dopaminergic systems in motivational processes, we suggest that motivational stimulation might act as a surrogate for dopaminergic stimulation. In addition, we consider the relationship between clinical post stroke apathy and lack of response to motivation.

    Lithium, which has the chemical symbol Li and an atomic number of 3, is the first metal in the periodic table. Lithium has many uses, the most prominent being in batteries for cell phones, laptops, and electric and hybrid vehicles. Worldwide sources of lithium are broken down by ore-deposit type as follows: closed-basin brines, 58%; pegmatites and related granites, 26%; lithium-enriched clays, 7%; oilfield brines, 3%; geothermal brines, 3%; and lithium-enriched zeolites, 3% (2013 statistics). There are over 39 million tons of lithium resources worldwide. Of this resource, the USGS estimates there to be approximately 13 million tons of current economically recoverable lithium reserves. To help predict where future lithium supplies might be located, USGS scientists study how and where identified resources are concentrated in the Earth’s crust, and they use that knowledge to assess the likelihood that undiscovered resources also exist.

  3. Harnessing migraines for neural regeneration

    Directory of Open Access Journals (Sweden)

    Jonathan M Borkum

    2018-01-01

    Full Text Available The success of naturalistic or therapeutic neuroregeneration likely depends on an internal milieu that facilitates the survival, proliferation, migration, and differentiation of stem cells and their assimilation into neural networks. Migraine attacks are an integrated sequence of physiological processes that may protect the brain from oxidative stress by releasing growth factors, suppressing apoptosis, stimulating neurogenesis, encouraging mitochondrial biogenesis, reducing the production of oxidants, and upregulating antioxidant defenses. Thus, the migraine attack may constitute a physiologic environment conducive to stem cells. In this paper, key components of migraine are reviewed – neurogenic inflammation with release of calcitonin gene-related peptide (CGRP and substance P, plasma protein extravasation, platelet activation, release of serotonin by platelets and likely by the dorsal raphe nucleus, activation of endothelial nitric oxide synthase (eNOS, production of brain-derived neurotrophic factor (BDNF and, in migraine aura, cortical spreading depression – along with their potential neurorestorative aspects. The possibility is considered of using these components to facilitate successful stem cell transplantation. Potential methods for doing so are discussed, including chemical stimulation of the TRPA1 ion channel, conjoint activation of a subset of migraine components, invasive and noninvasive deep brain stimulation of the dorsal raphe nucleus, transcranial focused ultrasound, and stimulation of the Zusanli (ST36 acupuncture point.

  4. Re-Harnessing the Genie

    Science.gov (United States)

    Lagowski, J. J.

    1996-06-01

    Fifty years ago Vannevar Bush, with the aid of the Federal Government, released the academic research genie. It was argued at the time, and it still may be true, that only academic laboratories could provide the research and trained personnel needed to sustain American's scientific and technological needs. As history has shown, Bush's instinctive distrust of industrial laboratories as a potential training ground was basically correct. In those days, the country's needs were associated with warfare-the end of WWII and the collective hostile activities historically described as the "cold war." Today the country's needs derive from attempts to stay globally competitive. The government's decision to have universities turning out the bulk of the nation's basic research and to use those universities as a venue for developing research talent has created a network of more than 100 research-intensive universities, the output of which is the envy of the world. But, now there is another growing national need-improving the quality of science, mathematics, engineering, and technology (SMET) education throughout the educational system. The genie released 50 years ago, either has to go back into the bottle, or it needs to be re-purposed. The former is highly unlikely, which leaves only the latter as a viable strategy. Indeed, the National Science Foundation, which could be described as the master of the genie, is attempting to do just that. In the past several years, the budget for NSF's suite of "undergraduate" programs has grown to the point where the Foundation currently spends about $180 million on such projects. These programs represent initiatives at the pre-college and undergraduate college levels that are focused on instructional activities (teacher preparation, curriculum development, faculty enhancement, etc.) and research-oriented activities to compliment undergraduate education in a variety of traditional nonresearch environments. These programs are an attempt by NSF to start redressing the imbalance between research and teaching that the Foundation has actively promoted during most of its 50 years of existence. Now, the NSF strategy is to tell the scientists it has supported in the past, and those who will be supported in the future, that what they do in the classroom is as important as what they do in the laboratory; indeed, some would argue it is the most important activity that NSF has to sustain in the current environment. Since NSF is part of the problem, it has an obligation to be part of the solution, which is the essence of a report of an advisory panel. The draft report also has suggestions to universities on how to revise their approach to SMET teaching. It recommends that departments should set goals for what their students should learn, hold faculty members accountable for students' performance, change the academic reward system to incorporate good teaching, and give science faculty members a bigger role in the education of K-12 teachers. The basic problem is that 65% of all undergraduates, including many who will become the nation's precollege teachers, do not attend the more than 100 research intensive institutions that are so heavily supported by NSF's research efforts. In effect, those students have no access to SMET education in a world of growing technical complexity. The report suggests that NSF would do well to redress this imbalance by shifting more of its resources into undergraduate and precollege programs that focus on teaching. This point of view grows out of a 1986 review which centered on how NSF could help science majors. Now, the Foundation is being asked to address the SMET-related problems of all undergraduate students. Clearly, there is danger in attempting to use a system, the relatively meager resources of which have been aimed at about 10% of the population of undergraduates, to serve the entire population. Still, NSF can send a clear message that teaching is important in research-intensive universities. A message that might have a catalytic effect on all institutions. JJL

    Pharmacogenomics harnesses the utility of a patient's genome (n = 1) in decisions on which therapeutic drugs and in what amounts should be administered. Often, patients with shared ancestry present with comparable genetic profiles that predict drug response. However, populations are not static, thus, often, population mobility through migration, especially enmasse as is seen for refugees, changes the pharmacogenetic profiles of resultant populations and therefore observed responses to commonly used therapeutic drugs. For example, in the aftermath of the Syrian civil war since 2011, millions have fled their homes to neighboring countries in the Middle East. The growing permanence of refugees and mass migrations is a call to shift our focus in the life sciences community from old models of pharmaceutical innovation. These seismic social changes demand faster decisions for "population-to-population bridging," whereby novel drugs developed in or for particular regions/countries can meet with rational regulatory decisions/approval in world regions impacted by migrant/refugee populations whose profiles are dynamic, such as in the Eastern Mediterranean region at present. Thus, it is important to characterize and report on the prevalence of pharmacogenes that affect commonly used medications and predict if population changes may call for attention to particular differences that may impact health of patients. Thus, we report here on four single-nucleotide polymorphism (SNP) variations in CYP2C9 and CYP2C19 genes among Mersin-Turkish healthy volunteers in the Mersin Province in the Eastern Mediterranean region that is currently hosting a vast number of migrant populations from Syria. Both CYP2C9 and CYP2C19 are very important pharmacogene molecular targets. We compare and report here on the observed SNP genetic variation in our sample with data on 12 world populations from dbSNP and discuss the feasibility of forecasting the pharmacokinetics of drugs utilized by migrant

  16. Improving the Photo-Oxidative Performance of Bi2MoO6 by Harnessing the Synergy between Spatial Charge Separation and Rational Co-Catalyst Deposition.

    It has been reported that photogenerated electrons and holes can be directed toward specific crystal facets of a semiconductor particle, which is believed to arise from the differences in their surface electronic structures, suggesting that different facets can act as either photoreduction or photo-oxidation sites. This study examines the propensity for this effect to occur in faceted, plate-like bismuth molybdate (Bi 2 MoO 6 ), which is a useful photocatalyst for water oxidation. Photoexcited electrons and holes are shown to be spatially separated toward the {100} and {001}/{010} facets of Bi 2 MoO 6 , respectively, by facet-dependent photodeposition of noble metals (Pt, Au, and Ag) and metal oxides (PbO 2 , MnO x , and CoO x ). Theoretical calculations revealed that differences in energy levels between the conduction bands and valence bands of the {100} and {001}/{010} facets can contribute to electrons and holes being drawn to different surfaces of the plate-like Bi 2 MoO 6 . Utilizing this knowledge, the photo-oxidative capability of Bi 2 MoO 6 was improved by adding an efficient water oxidation co-catalyst, CoO x , to the system, whereby the extent of enhancement was shown to be governed by the co-catalyst location. A greater oxygen evolution occurred when CoO x was selectively deposited on the hole-rich {001}/{010} facets of Bi 2 MoO 6 compared to when CoO x was randomly located across all of the facets. The elevated performance exhibited for the selectively loaded CoO x /Bi 2 MoO 6 was ascribed to the greater opportunity for hole trapping by the co-catalyst being accentuated over other potentially detrimental effects, such as the co-catalyst acting as a recombination medium and/or covering reactive sites. The results indicate that harnessing the synergy between the spatial charge separation and the co-catalyst location on the appropriate facets of plate-like Bi 2 MoO 6 can promote its photocatalytic activity.

    The soil moisture movement is an important carrier of material cycle and energy flow among the various geo-spheres in the cold regions. It is very critical to protect the alpine ecology and hydrologic cycle in Qinghai-Tibet Plateau. Especially, it becomes one of the key problems to reveal the spatial-temporal variability of soil moisture movement and its main influence factors in earth system science. Thus, this research takes the north slope of Bayan Har Mountains in Qinghai-Tibet Plateau as a case study. The present study firstly investigates the change of permafrost moisture in different slope positions and depths. Based on this investigation, this article attempts to investigate the spatial variability of permafrost moisture and identifies the key influence factors in different terrain conditions. The method of classification and regression tree (CART) is adopted to identify the main controlling factors influencing the soil moisture movement. And the relationships between soil moisture and environmental factors are revealed by the use of the method of canonical correspondence analysis (CCA). The results show that: 1) the change of the soil moisture on the permafrost slope is divided into 4 stages, including the freezing stability phase, the rapid thawing phase, the thawing stability phase and the fast freezing phase; 2) this greatly enhances the horizontal flow in the freezing period due to the terrain slope and the freezing-thawing process. Vertical migration is the mainly form of the soil moisture movement. It leads to that the soil-moisture content in the up-slope is higher than that in the down-slope. On the contrary, the soil-moisture content in the up-slope is lower than that in the down-slope during the melting period; 3) the main environmental factors which affect the slope-permafrost soil-moisture are elevation, soil texture, soil temperature and vegetation coverage. But there are differences in the impact factors of the soil moisture in different

    The accelerated work life – a study of how acceleration affects contemporary work life The field of accelerated life became an interest as a result of the reading of Alienation and Acceleration (2010) by sociologist Hartmut Rosa. Rosa presents a crucial new chapter in the history of critical theory, which I believe will resonate far into the future. The theory highlights the most essential paradoxical parts of contemporary work life and contemporary life in general, in a structured and refine...

    Full Text Available The meaning of music at a large farm during the inter-war period This article investigates music as culture from a historical, ethno-musicological perspective. Jens Henrik Koudal bases his work on the preserved music collection and large private archives of Christian Olsen (1881–1968, who was born and spent most of his life on the farm Torpelund in Zealand, Denmark. From Olsen’s collection, it is possible to make a historical reconstruction of the  rich musical life that took place on the farm, and the purpose of the article is to examine what the musical activities meant to the Olsen family’s social and cultural identity; i.e., both their self-conceptualisation and their marking of identity towards their surroundings. The article’s method is rooted in a ‘broad’ concept of culture, along with Christopher Small’s concept ‘musicking’ and new musicology’s tendency to focus on the practice of music-making rather than on ‘great’ composers and books of music. Torpelund is compared to similar settings in England (e.g., East Suffolk around 1900, according to Carole Pegg and Western concert halls (around 1980, according to Christopher Small. During the inter-war period, the Olsen family gathered together a circle of diverse people, including relatives, friends, business connections and other musicians, who all participated in the  “musicking” as equals. Their repertoire consisted of classical and  romantic art music from c. 1780–1890, plus the family’s old folk-dancing music (arranged by members of the family.

    The purpose of the project was to provide evidence of power saving based on measurements in electric installations, in which the harmonics were reduced by active filters. The project has included knowledge building on the basis of literature and discussions with a Swedish and a Belgian producer of active filters. In connection with the project, tests have been made on a production line at the firm of Faerch Plast, where the distortion from the harmonics, measured as THDU, was 6 to 7 %. Measurements during two days with the active filter switched on and off with an interval of 10 minutes showed a very small difference in power input in the two situations. The power was 2.7 kW higher with connected filter than without filter. As the own consumption of the filter was 5.8 kW, the consumption of the installation itself was 3.1 kW lower, equal to 1 % of the load of the directly supplied induction motors. As a consequence of the very small differences, measured at Faerch Plast, it was decided to transfer the further work to a laboratory in order to measure under so controlled circumstances as possible. Measurements have been taken at KME (Copenhagen School of Marine Engineering and Technology Management) and at TI (Danish Technological Institute). The result of measurements on a 5.5 kW induction motor with a distortion from the harmonics (THDU) of 2.65 % shows no significant change in the input power compared to the situation with almost no distortion. Neither, it appears, is there a significant difference in the motor losses in a situation, where the measurement was taken with two rather distorted mains voltages with a THDU of 6.33 % and 7.66 %, respectively. Calculations on the basis of the equivalent diagram of the motor show that the additional motor losses in a 5.5 kW motor as a consequence of 5. harmonics of 5 % of the mains voltage (THDU 5 %) only is 2 W, while an experimentally derived formula results in a difference of approx 9 W or 0.2 % of the rated power of the motor. The results of the lab measurements correspond very well to the losses calculated. On this basis it is concluded that harmonic currents and voltages cause energy losses in induction motors directly supplied, but that the energy losses are fairly low at the levels of distortion, a THDU of up to 6 to 8 %, which occur in Danish industry. Motors, which are supplied through a frequency converter, are not influenced by the harmonics in the supply mains. The analysis of the motor losses shows that the losses from the load torque, caused by the 5., 11., 17. etc harmonics, are considerably lower than the (very small) current heat losses in the motor, which have been caused by the same harmonics. The analysis also shows that the current displacement in the motors reduces the currents and the losses from the higher harmonics. Considering losses consequently the lower harmonics and especially 5. and 7. harmonics are most important. (LN)

  12. Harnessing genomics for delineating conservation units.

    Funk, W Chris; McKay, John K; Hohenlohe, Paul A; Allendorf, Fred W

    2012-09-01

    Genomic data have the potential to revolutionize the delineation of conservation units (CUs) by allowing the detection of adaptive genetic variation, which is otherwise difficult for rare, endangered species. In contrast to previous recommendations, we propose that the use of neutral versus adaptive markers should not be viewed as alternatives. Rather, neutral and adaptive markers provide different types of information that should be combined to make optimal management decisions. Genetic patterns at neutral markers reflect the interaction of gene flow and genetic drift that affects genome-wide variation within and among populations. This population genetic structure is what natural selection operates on to cause adaptive divergence. Here, we provide a new framework to integrate data on neutral and adaptive markers to protect biodiversity. Copyright © 2012 Elsevier Ltd. All rights reserved.

    2005-04-01

    Full Text Available Data warehousing architecture should generally protect the confidentiality of data before it can be published, provide sufficient granularity to enable scientists to variously manipulate data, support robust metadata services, and define standardized spatial components. Data can then be transformed into information that would make them readily available in a common format that is easily accessible, fast, and bridges the islands of dispersed information. The benefits of the warehouse can be further enhanced by adding a spatial component so that the data can be brought to life, overlapping layers of information in a format that is easily grasped by management, enabling them to tease out trends in their areas of expertise.

  20. HARNESSING VALUES TO PROMOTE MOTIVATION IN EDUCATION.

    Harackiewicz, Judith M; Tibbetts, Yoi; Canning, Elizabeth; Hyde, Janet S

    2014-01-01

    We review the interventions that promote motivation in academic contexts, with a focus on two primary questions: How can we motivate students to take more STEM courses? Once in those STEM courses, how can we keep students motivated and promote their academic achievement? We have approached these two motivational questions from several perspectives, examining the theoretical issues with basic laboratory research, conducting longitudinal questionnaire studies in classrooms, and developing interventions implemented in different STEM contexts. Our research is grounded in three theories that we believe are complementary: expectancy-value theory (Eccles & Wigfield, 2002), interest theory (Hidi & Renninger, 2006), and self-affirmation theory (Steele, 1988). As social psychologists, we have focused on motivational theory and used experimental methods, with an emphasis on values - students' perceptions of the value of academic tasks and students' personal values that shape their experiences in academic contexts. We review the experimental field studies in high-school science and college psychology classes, in which utility-value interventions promoted interest and performance for high-school students in science classes and for undergraduate students in psychology courses. We also review a randomized intervention in which parents received information about the utility value of math and science for their teens in high school; this intervention led students to take nearly one semester more of science and mathematics, compared with the control group. Finally, we review an experimental study of values affirmation in a college biology course and found that the intervention improved performance and retention for first-generation college students, closing the social-class achievement gap by 50%. We conclude by discussing the mechanisms through which these interventions work. These interventions are exciting for their broad applicability in improving students' academic choices and performance, they are also exciting regarding their potential for contributions to basic science. The combination of laboratory experiments and field experiments is advancing our understanding of the motivational principles and almost certainly will continue to do so. At the same time, interventions may benefit from becoming increasingly targeted at specific motivational processes that are effective with particular groups or in particular contexts.

    The recursion method of Haydock, Heine and Kelly is a powerful tool for calculating diagonal matrix elements of the resolvent of quantum-mechanical Hamiltonian operators by elegantly expressing them in terms of continued fractions. In this paper we extend the recursion method to off-diagonal matrix elements of general (possibly non-Hermitian) operators and apply it to the simulation of molecular optical absorption and photoemission spectra within time-dependent density-functional and many-body perturbation theories, respectively. This method is demonstrated with a couple of applications to the optical absorption and photoemission spectra of the caffeine molecule.

    2017-01-01

    Comparative genome sequencing studies of human fungal pathogens enable identification of genes and variants associated with virulence and drug resistance. This review describes current approaches, resources, and advances in applying whole genome sequencing to study clinically important fungal pathogens. Genomes for some important fungal pathogens were only recently assembled, revealing gene family expansions in many species and extreme gene loss in one obligate species. The scale and scope of species sequenced is rapidly expanding, leveraging technological advances to assemble and annotate genomes with higher precision. By using iteratively improved reference assemblies or those generated de novo for new species, recent studies have compared the sequence of isolates representing populations or clinical cohorts. Whole genome approaches provide the resolution necessary for comparison of closely related isolates, for example, in the analysis of outbreaks or sampled across time within a single host. Genomic analysis of fungal pathogens has enabled both basic research and diagnostic studies. The increased scale of sequencing can be applied across populations, and new metagenomic methods allow direct analysis of complex samples.

  5. How Effective Leaders Harness the Future.

    2018-02-01

    Human beings are fundamentally future oriented. Most of our decisions and undertakings are for the sake of a future to which we are committed or obligated. This future orientation is essential to effective leadership in health care, especially during this time of significant reform, when people are at risk of becoming cynical and disengaged. Conventional thinking holds that our effectiveness as leaders is primarily a function of what we have learned in the past-our knowledge, expertise, and experience. In contrast, the emerging model contends that our effectiveness is also a function of how the future (outcome) of our leadership challenges "shows up" for us. If, despite daunting circumstances, we can "see" an aspired future ahead, we are more likely to commit and engage. Our story of the future becomes the "narrative frame" through which we see and tackle leadership challenges today. Because organizations are fundamentally networks of conversations, an organization's ability to create new language practices is tantamount to its ability to evolve. What makes the future compelling is the embodiment of our deepest convictions and ideals in our image of the future. Because health care reform has challenged the medical profession along the entire spectrum of its traditional values and roles, working toward a unifying vision of the future has been difficult. To enroll others in creating a better future, effective leaders must underscore the purpose and importance of their work and motivate them with inspiring stories.

    Science.gov (United States)

    Sherson, Jacob

    In the emerging field of citizen science ordinary citizens have already contributed to research in as diverse fields as astronomy, protein and RNA folding, and neuron mapping by playing online games. In the www.scienceathome.org project, we have extended this democratized research to the realm of quantum physics by gamifying a class of challenges related to optimization of gate operations in a quantum computer. The games have been played by more than 150,000 players and perhaps surprisingly we observe that a large fraction of the players outperform state-of-the-art optimization algorithms. With a palette of additional games within cognitive science, behavioral economics, and corporate innovation we investigate the general features of individual and collaborative problem solving to shed additional light on the process of human intuition and innovation and potentially develop novel models of artificial intelligence. We have also developed and tested in classrooms educational games within classical and quantum physics and mathematics at high-school and university level. The games provide individualized learning and enhance motivation for the core curriculum by actively creating links to modern research challenges, see eg. Finally, we have recently launched our new democratic lab: an easily accessible remote interface for our ultra-cold atoms experiment allowing amateur scientists, students, and research institutions world-wide to perform state-of-the-art quantum experimentation. In first tests, nearly a thousand players helped optimize the production of our BEC and discovered novel efficient strategies.

  11. Harnessing natural diversity to probe metabolic pathways.

    Directory of Open Access Journals (Sweden)

    Oliver R Homann

    2005-12-01

    Full Text Available Analyses of cellular processes in the yeast Saccharomyces cerevisiae rely primarily upon a small number of highly domesticated laboratory strains, leaving the extensive natural genetic diversity of the model organism largely unexplored and unexploited. We asked if this diversity could be used to enrich our understanding of basic biological processes. As a test case, we examined a simple trait: the utilization of di/tripeptides as nitrogen sources. The capacity to import small peptides is likely to be under opposing selective pressures (nutrient utilization versus toxin vulnerability and may therefore be sculpted by diverse pathways and strategies. Hitherto, dipeptide utilization in S. cerevisiae was solely ascribed to the activity of a single protein, the Ptr2p transporter. Using high-throughput phenotyping and several genetically diverse strains, we identified previously unknown cellular activities that contribute to this trait. We find that the Dal5p allantoate/ureidosuccinate permease is also capable of facilitating di/tripeptide transport. Moreover, even in the absence of Dal5p and Ptr2p, an additional activity--almost certainly the periplasmic asparaginase II Asp3p--facilitates the utilization of dipeptides with C-terminal asparagine residues by a different strategy. Another, as-yet-unidentified activity enables the utilization of dipeptides with C-terminal arginine residues. The relative contributions of these activities to the utilization of di/tripeptides vary among the strains analyzed, as does the vulnerability of these strains to a toxic dipeptide. Only by sampling the genetic diversity of multiple strains were we able to uncover several previously unrecognized layers of complexity in this metabolic pathway. High-throughput phenotyping facilitates the rapid exploration of the molecular basis of biological complexity, allowing for future detailed investigation of the selective pressures that drive microbial evolution.

  19. Neuromarkers for Mental Disorders: Harnessing Population Neuroscience

    Directory of Open Access Journals (Sweden)

    Lee Jollans

    2018-06-01

    Full Text Available Despite abundant research into the neurobiology of mental disorders, to date neurobiological insights have had very little impact on psychiatric diagnosis or treatment. In this review, we contend that the search for neuroimaging biomarkers—neuromarkers—of mental disorders is a highly promising avenue toward improved psychiatric healthcare. However, many of the traditional tools used for psychiatric neuroimaging are inadequate for the identification of neuromarkers. Specifically, we highlight the need for larger samples and for multivariate analysis. Approaches such as machine learning are likely to be beneficial for interrogating high-dimensional neuroimaging data. We suggest that broad, population-based study designs will be important for developing neuromarkers of mental disorders, and will facilitate a move away from a phenomenological definition of mental disorder categories and toward psychiatric nosology based on biological evidence. We provide an outline of how the development of neuromarkers should occur, emphasizing the need for tests of external and construct validity, and for collaborative research efforts. Finally, we highlight some concerns regarding the development, and use of, neuromarkers in psychiatric healthcare.

    Horse domestication revolutionized transport, communications, and warfare in prehistory, yet the identification of early domestication processes has been problematic. Here, we present three independent lines of evidence demonstrating domestication in the Eneolithic Botai Culture of Kazakhstan, dating to about 3500 B.C.E. Metrical analysis of horse metacarpals shows that Botai horses resemble Bronze Age domestic horses rather than Paleolithic wild horses from the same region. Pathological characteristics indicate that some Botai horses were bridled, perhaps ridden. Organic residue analysis, using delta13C and deltaD values of fatty acids, reveals processing of mare's milk and carcass products in ceramics, indicating a developed domestic economy encompassing secondary products.
