    Poka-Yoke is the Japanese term for mistake-proofing. Developed by Dr. Shigeo Shingo, Poka-Yoke employs devices on the process operations to prevent the special causes that result in defects, or to inexpensively inspect each item that is produced to determine whether it is acceptable or defective

    Poka Yoke is a method of quality management which is related to prevent faults from arising during production processes. It deals with “fail-sating” or “mistake-proofing”. The Poka-yoke concept was generated and developed by Shigeo Shingo for the Toyota Production System. Poka Yoke is used in many fields, especially in monitoring production processes. In many cases, identifying faults in a production process involves a higher cost than necessary cost of disposal. Usually, poke yoke solutions are based on multiple sensors that identify some nonconformities. This means the presence of different equipment (mechanical, electronic) on production line. As a consequence, coupled with the fact that the method itself is an invasive, affecting the production process, would increase its price diagnostics. The bulky machines are the means by which a Poka Yoke system can be implemented become more sophisticated. In this paper we propose a solution for the Poka Yoke system based on image analysis and identification of faults. The solution consists of a module for image acquisition, mid-level processing and an object recognition module using associative memory (Hopfield network type). All are integrated into an embedded system with AD (Analog to Digital) converter and Zync 7000 (22 nm technology).

    Full Text Available This paper has the purpose of analyzing methods, techniques and guidelines for the design, operation and maintenance of poka-yoke systems. In parallel it intends to contribute with concepts about what poka-yoke are and their classification. Therefore a literature review was made about systems poka-yoke concepts, poka-yoke systems classification, kinds of inspections, kinds of mistakes, the relationship between stability and statistical process control with mistake proofing systems, techniques and directions to design and manage poka-yoke. An analysis was carried out with each subject relating poka-yoke with the subject. At the end the absence of a poka-yoke management system was evident, because techniques for design, operation and maintenance aren’t consistent.

  5. Universal design of workplaces through the use of Poka-Yokes: Case study and implications

    2011-10-01

    Full Text Available Purpose: Employment plays an important part in many people’s lives beyond merely providing income, since continued participation in work can have many therapeutic benefits for workers defined as disabled. However, disabled workers face a range of barriers to employment, despite legislation intended to improve workplace accessibility emphasizing adaptations to the workplace, which many employers often find difficult and expensive. The Poka-Yoke approach was developed in the manufacturing industry as a way of improving productivity by reducing errors using often very simple adaptations. This paper argues that, as Poka-Yokes are designed to make life easier and improve the performance of workers without impairments, they are closer to the philosophy of Universal Design than to Accessible Design, and offer an easy and inclusive way of making work more accessible for all kind of workers. Design/methodology/approach: This paper provides a case study demonstrating the use of the Poka-Yoke approach in a sheltered work centre for disabled; highlighting how they served to improve accessibility to work by fulfilling Universal Design principles. Findings: Our research allows us to demonstrate the great potential of Poka-yokes for gaining accessibility to the workplace. The real application of this approach, both in sheltered work centres and ordinary companies, can contribute to improve the high unemployment rates of disabled people. Research limitations/implications: The proposal is innovative and was applied in one specific company. Thus, a range of customized Poka-yokes would be desirable for different industrial sectors. Practical implications: Managers of sheltered work centres, and also of ordinary companies, can realize about the great potential of Poka-Yokes as an easy means of gaining flexibility and accessibility. Originality/value: There are very few papers relating lean manufacturing tools and disability. Our approach analyzes the benefits of

    ENGLISH ABSTRACT: In this project an electronic manufacturing process, namely ribbon cable assembly, was adapted for execution by intellectually disabled individuals. To make the work accessible to them, human error was controlled by a Poka-yoke approach. The design of the work process used industry standard tooling. Mistake-proofing design identified possible errors, and introduced mechanisms and tests that enabled the worker to avoid them. Test results were analysed using learning theory. It is concluded that intellectually disabled individuals can be enabled to perform the task within normal variation compared with a minimum task time, by using the Poka-yoke approach. Selection, however, is desirable.

    2017-11-01

    Integration of Poka Yoke and TRIZ is a method of solving problems by using a different approach. Poka Yoke is a trial and error method while TRIZ is using a systematic approach. The main purpose of this technique is to get rid of product defects by preventing or correcting errors as soon as possible. Blame the workers for their mistakes is not the best way, but the work process should be reviewed so that every workers behavior or movement may not cause errors. This study is to demonstrate the importance of using both of these methods in which everyone in the industry needs to improve quality, increase productivity and at the same time reducing production cost.

    1998-09-01

    Job performance and production related issues are important not only to successful vocational training and ultimate job placement for individuals with cognitive disabilities, but also for their ability to have expanded vocational options. This study hypothesized that the application of Kaizen philosophy, and poka-yoke techniques in particular, could create job opportunities and improve productivity of individuals with cognitive disabilities. Poka-yoke or error-proofing techniques are part of the collection of Kaizen techniques. Kaizen refers to continuous improvement in performance, cost/effectiveness, and quality. Kaizen strives to empower the worker, increase worker satisfaction, facilitate a sense of accomplishment, and thereby create pride-of-work. These techniques typically reduce the physical and cognitive demands of a task and thereby render the task more accessible. The job was a fuel clamp assembly. A redesigned assembly fixture was the poka-yoke intervention. Consistent with poka-yoke principles, the intervention improved the productivity of everyone attempting the assembly. In particular, the workers in this study showed an 80% increase in productivity and an average percent error drop from 52% to about 1% after the process redesign. Furthermore, the workers showed improved morale, self-esteem, and pride-of-work. Prior to the process redesign, only the higher functioning workers could successfully perform the assembly. After the redesign a greater number of workers could successfully perform the assembly. These results not only validated the study hypothesis, but demonstrated that the success facilitated by applying Kaizen techniques had similar results with individuals with cognitive disabilities as with nondisabled workers.

    Nicolás Lavagnino

    2011-04-01

    Full Text Available This article addresses three issues closely related to current developments in philosophy and epistemology of history. First, it addresses the narrative deployment of historiographic discourse according to the original framework of Hayden White’s narrativist philosophy of history, centered on tropology as a basic method of historical cognition. Secondly, it examines how the application of tropology to historiography has raised questions about the status of historical knowledge, resulting in concerns about relativism, “linguistic solipsism”, truth, and justification. Finally, the paper addresses the fact that narrativism has been seen as opting for a merely literary or fictional view of the past. On that basis, it goes on to propose a narrativist perspective that avoids skeptical and relativistic interpretations, while at the same time reconsidering the concept of literature as a better way of understanding the tropological nature of the language used to give an account of the past.

    Full Text Available Como objetivo, este artigo pretende identificar como o método Poka Yoke contribui para evitar erros, corrigindo defeitos na execução de peças caldeiradas. Como justificativa para a escolha desse tema destaca-se que as empresas cada vez mais investem na qualidade de seus processos de produção, sendo o desperdício algo que sinaliza falhas e que os mecanismos de averiguação dos meios de controle necessitam ser cada vez mais aprimorados. A linha de pesquisa utilizada para tal estudo está na sistematização in loco de como se dará o fluxo do processo do método Poka Yoke na sua aplicação em peças caldeiradas. A metodologia será em etapas definidas de controle, incluindo avaliação quantitativa e qualitativa dos erros, identificando-se os processos de falhas, bem como melhorias de produção, bem como avaliando como se dá o retrabalho e de maneira esse se dá no processo de controle de eficácia da linha de produção. Cabe ressaltar que este trabalho destina-se à instrumentalização de que a Engenharia de Produção se apropria e utiliza no que se refere ao desenvolvimento voltado ao processo de gestão, incluindo-se assim o foco principal de formação que a instituição particulariza. Foi visto na pesquisa que o sistema funciona ainda mais quando há uma conscientização dos trabalhadores para a importância da metodologia aplicada nos processos de produção.

    Full Text Available Se abordan tres cuestiones estrechamente relacionadas con los desarrollos actuales en filosofía y epistemología de la historia. En primer lugar, se pretende dar cuenta del despliegue narrativo del discurso historiográfico siguiendo los lineamientos originales de la filosofía narrativista de la historia de Hayden White centrada en la tropología como método básico de la cognición histórica. En segundo lugar, la aplicación de la tropología a la historiografía ha suscitado dudas acerca del estatus del conocimiento histórico y ha derivado en la recaída en una problemática transida por preocupaciones como el relativismo, el "solipsismo lingüístico", la verdad y la justificación. Por último, el narrativismo ha sido considerado como una apuesta por la consideración meramente literaria o ficcional del pasado. Se propone una perspectiva narrativista que coarte las interpretaciones escépticas, relativistas, y que a la vez reconsidere el concepto de literatura como una mejor forma de comprender el carácter tropológico de los usos lingüísticos que pretenden dar cuenta del pasado.

  16. Firewalls and flat mirrors: An alternative to the AMPS experiment which evades the Harlow-Hayden obstacle

    International Nuclear Information System (INIS)

    Oppenheim, Jonathan; Unruh, Bill

    2014-01-01

    If quantum gravity does not lead to a breakdown of predictability, then Almheiri-Marolf-Polchinski-Sully (AMPS) have argued that an observer falling into a black hole can perform an experiment which verifies a violation of entanglement monogamy — that late time Hawking radiation is maximally entangled with early time Hawking radiation and also with in-falling radiation — something impossible in quantum field theory. However, as pointed out by Hayden and Harlow, this experiment is infeasible, as the time required to perform the experiment is almost certainly longer than the lifetime of the black hole. Here we propose an alternative firewall experiment which could actually be performed within the black hole’s lifetime. The alternative experiment involves forming an entangled black hole in which the unscrambling of information is precomputed on a quantum memory prior to the creation of the black hole and without acting on the matter which forms the black hole or emerges from it. This would allow an observer near a black hole to signal faster than light. As another application of our precomputing strategy, we show how one can produce entangled black holes which acts like “flat mirrors”, in the sense that information comes out almost instantly (as in the Hayden-Preskill scenario), but also emerge unscrambled, so that it can actually be observed instantly as well. Finally, we prove that a black hole in thermal equilibrium with its own radiation, is uncorrelated with this radiation

    2014-12-01

    Full Text Available "Historiofotia" foi o termo cunhado por Hayden White para designar a representação da história por meio de imagens visuais. Atualmente o termo é apropriado pelos historiadores para compreender como filmes produzem interpretações do passado. Para fins teóricos e metodológicos da prática histórica, deve-se identificar a gênese do conceito nos escritos de Hayden White. O visual parece ter sido questão menor na obra de White, ainda que jamais ausente, e o conceito de historiofotia faz parte de uma linhagem de noções alternativas, tais quais "aural", "espectral", "fantasmagoria", os quais aparecerem em distintos momentos nos seus escritos. O objetivo deste texto é evidenciar quais são as noções de "imagem" apresentadas por White em suas duas linhagens principais: a da imagem verbal, relacionada com a tropologia e as figuras de linguagem, e a da imagem não verbal, da qual fazem parte os termos mencionados acima. Nossa hipótese é que o esforço teórico de White na montagem de sua teoria dos tropos para explicar a construção do passado no texto histórico encontrou um limite nas imagens visuais. Para transpor este limite propomos uma problematização da historiofotia como uma ferramenta para compreensão dos usos públicos visuais das figurações do passado na cultura histórica das sociedades industriais e pós-industriais.

  20. Are the dinosauromorph femora from the Upper Triassic of Hayden Quarry (New Mexico) three stages in a growth series of a single taxon?

    Science.gov (United States)

    Müller, Rodrigo T

    2017-01-01

    The lagerpetid Dromomeron romeri and the theropod Tawa hallae are two dinosauromorphs from the Norian (Upper Triassic) of the Chinle Formation, situated in New Mexico, USA. However, a recent study suggests the inclusion of the holotype of D. romeri (GR 218) and paratype (GR 155) and referred (GR 235) specimens of T. hallae in an ontogenetic series of a single species. The specimens GR 218 and GR 155 include just an isolated femur, while GR235 includes femora, pelvis and tail. The inclusion of the specimens in an unique ontogenetic series relies on the putative immature condition and plastic deformation of the specimen GR 218. However, as observed here, the disparity between the femora of D. romeri and T. hallae is considerably higher than those expected from the ontogenetic variance in dinosauromorphs. In addition, D. romeri shares an unique suite of traits with Dromomeron gigas, a species known from a mature specimen. Therefore, the high disparity between D. romeri and T. hallae, lack of traits shared solely between the three femora, and a suite of traits shared between D. romeri and D. gigas, precludes the inclusion of the three femora from Hayden Quarry in a growth series of a single taxon.

    Fish populations were studied in the Central Arizona Project's canal system during the first 4 years of aqueduct operation (1986-1989). Ichthyoplankton entering the canal from Lake Havasu averaged 1 larva/m3 during April-June 1987 and 1988. Larval fish densities increased significantly in downstream samples, substantiating diver observations that fish were spawning in the canal system. Of the 16 fish species collected, 14 were assumed to have originated from Lake Havasu and 2 were introduced by anglers from their bait buckets. Initially, the fish community was dominated numerically by threadfin shad Dorosoma petenense (>88%), centrarchids (planned operational conditions, the fish community continued to represent a potentially valuable, but as yet unused, resource.

    Abstract: Researchers, policymakers, business, and industry have indicated that the United States will experience a future shortage of professionals in the Science, Technology, Engineering, and Mathematics (STEM) fields. Several strategies have been suggested to address this impending shortage, one of which includes increasing the representation of females and minorities in the STEM fields. In order to increase the representation of underrepresented students in the STEM fields, it is important to understand the motivational factors that impact underrepresented students' interest in STEM academics and extracurricular programs. Research indicates that greater confidence leads to greater interest and vice versa (Denissen et al., 2007). In this paper, the mathematics research team examined the role of practical research experience during the summer for talented minority secondary students studying in STEM fields. An undergraduate research mathematics team focused on the link between summer research and the choice of an undergraduate discipline. A Chi Square Statistical Test was used to examine Likert Scale results on the attitude of students participating in the 2006-2012 Center for Remote Sensing of Ice Sheets (CReSIS) Summer Research Programs for secondary students. This research was performed at Elizabeth City State University located in northeastern North Carolina about the factors that impact underrepresented students' choices of STEM related majors in college. Results can be used to inform and guide educators, administrators, and policy makers in developing programs and policy that support and encourage the STEM development of underrepresented students.

    Varicella-zoster virus (VZV) establishes latency in human sensory and cranial nerve ganglia during primary infection (varicella), and the virus can reactivate and cause zoster after primary infection. The mechanism of how the virus establishes and maintains latency and how it reactivates is poorly understood, largely due to the lack of robust models. We found that axonal infection of neurons derived from hESCs in a microfluidic device with cell-free parental Oka (POka) VZV resulted in latent infection with inability to detect several viral mRNAs by reverse transcriptase-quantitative PCR, no production of infectious virus, and maintenance of the viral DNA genome in endless configuration, consistent with an episome configuration. With deep sequencing, however, multiple viral mRNAs were detected. Treatment of the latently infected neurons with Ab to NGF resulted in production of infectious virus in about 25% of the latently infected cultures. Axonal infection of neurons with vaccine Oka (VOka) VZV resulted in a latent infection similar to infection with POka; however, in contrast to POka, VOka-infected neurons were markedly impaired for reactivation after treatment with Ab to NGF. In addition, viral transcription was markedly reduced in neurons latently infected with VOka compared with POka. Our in vitro system recapitulates both VZV latency and reactivation in vivo and may be used to study viral vaccines for their ability to establish latency and reactivate. PMID:27078099

    Kumar, Sameer; Livermont, Gregory; McKewan, Gregory

    2010-01-01

    The use of radio frequency identification device (RFID) technology within the healthcare industry was researched and specific instances of implementation of this technology in the hospital environment were examined. The study primarily makes use of ideas from operations and supply chain management, such as work flow diagrams, value stream mapping, and poka-yokes (mistake proofing measures) for investigations of processes, failures, and solutions. This study presents a step-by-step approach of how to implement the use of RFID tracking systems within the entire hospital. A number of poka-yokes were also devised for improving the safety of the patient and cost effectiveness of the hospital to insure the success of the hospital health care delivery system. Many players in the hospital environment may be impacted. This includes patients, doctors, nurses, technicians, administrators, and other hospital personnel. Insurance and government agencies may be impacted as well. Different levels of training of hospital personnel will be required based on the degree of interaction with the RFID system. References to costs, Return On Investment, change management, ethical and legal considerations are also made to help the reader understand the benefits and implications of the technology in the hospital environment.

  11. RFID in healthcare: a Six Sigma DMAIC and simulation case study.

    Southard, Peter B; Chandra, Charu; Kumar, Sameer

    2012-01-01

    The purpose of this paper is to develop a business model to generate quantitative evidence of the benefits of implementing radio frequency identification (RFID) technology, limiting the scope to outpatient surgical processes in hospitals. The study primarily uses the define-measure-analyze-improve-control (DMAIC) approach, and draws on various analytical tools such as work flow diagrams, value stream mapping, and discrete event simulation to examine the effect of implementing RFID technology on improving effectiveness (quality and timeliness) and efficiency (cost reduction) of outpatient surgical processes. The analysis showed significant estimated annual cost and time savings in carrying out patients' surgical procedures with RFID technology implementation for the outpatient surgery processes in a hospital. This is largely due to the elimination of both non-value added activities of locating supplies and equipment and also the elimination of the "return" loop created by preventable post operative infections. Several poka-yokes developed using RFID technology were identified to eliminate those two issues. Several poka-yokes developed using RFID technology were identified for improving the safety of the patient and cost effectiveness of the operation to ensure the success of the outpatient surgical process. Many stakeholders in the hospital environment will be impacted including patients, physicians, nurses, technicians, administrators and other hospital personnel. Different levels of training of hospital personnel will be required, based on the degree of interaction with the RFID system. Computations of costs and savings will help decision makers understand the benefits and implications of the technology in the hospital environment.

  12. Associate editors' foreword: entrepreneurship in health education and health promotion: five cardinal rules.

    Science.gov (United States)

    Cottrell, Randall R; Cooper, Hanna

    2009-07-01

    A career in health education or health promotion (HE/HP) can be developed in many ways. In past editions of this department, career development has been discussed in relation to distance (Balonna, 2001), consulting (Bookbinder, 2001), certifications (Hayden, 2005), graduate school (Cottrell & Hayden, 2007), and many other topics. This article looks at a less traditional means of career development-entrepreneurship. Health education is a field ripe with opportunities for consulting and for selling health-related products and services. Entrepreneurship can not only create financial rewards but can also provide high visibility and networking contacts that can advance one's career. This article combines both theory and practical applications to assist readers in developing entrepreneurial activities. The authors are experienced in entrepreneurial development and use that expertise to provide relevant examples and develop a framework using "five cardinal rules" for establishing an entrepreneurial enterprise in HE/HP.

    Images of distant and unknown places have long stimulated the imaginations of both explorers and scientists. The atlas of photographs collected during the Hayden (1872) expedition to the Yellowstone region was essential to its successful advocacy and selection in 1872 as America's ӿrst national park. Photographer William Henry Jackson of the Hayden expedition captured the public's imagination and support, returning home with a treasure of images that conӿrmed the existence of western landmarks previously regarded as gloriӿed myths: the Grand Tetons, Old Faithful, and strange pools of boiling hot mud. Fifty years later, photographer Ansel Adams began his long legacy of providing the public with compilations of iconic images of natural wonders that many only see in prints.

  20. Magma mixing and the generation of isotopically juvenile silicic magma at Yellowstone caldera inferred from coupling 238U–230Th ages with trace elements and Hf and O isotopes in zircon and Pb isotopes in sanidine

    2013-01-01

    The nature of compositional heterogeneity within large silicic magma bodies has important implications for how silicic reservoirs are assembled and evolve through time. We examine compositional heterogeneity in the youngest (~170 to 70 ka) post-caldera volcanism at Yellowstone caldera, the Central Plateau Member (CPM) rhyolites, as a case study. We compare 238U–230Th age, trace-element, and Hf isotopic data from zircons, and major-element, Ba, and Pb isotopic data from sanidines hosted in two CPM rhyolites (Hayden Valley and Solfatara Plateau flows) and one extracaldera rhyolite (Gibbon River flow), all of which erupted near the caldera margin ca. 100 ka. The Hayden Valley flow hosts two zircon populations and one sanidine population that are consistent with residence in the CPM reservoir. The Gibbon River flow hosts one zircon population that is compositionally distinct from Hayden Valley flow zircons. The Solfatara Plateau flow contains multiple sanidine populations and all three zircon populations found in the Hayden Valley and Gibbon River flows, demonstrating that the Solfatara Plateau flow formed by mixing extracaldera magma with the margin of the CPM reservoir. This process highlights the dynamic nature of magmatic interactions at the margins of large silicic reservoirs. More generally, Hf isotopic data from the CPM zircons provide the first direct evidence for isotopically juvenile magmas contributing mass to the youngest post-caldera magmatic system and demonstrate that the sources contributing magma to the CPM reservoir were heterogeneous in 176Hf/177Hf at ca. 100 ka. Thus, the limited compositional variability of CPM glasses reflects homogenization occurring within the CPM reservoir, not a homogeneous source.

  3. The Geologic Story of the Uinta Mountains

    Hansen, Wallace R.

    1969-01-01

    The opening of the West after the Civil War greatly stimulated early geologic exploration west of the 100th Meridian. One of the areas first studied, the Uinta Mountains region, gained wide attention as a result of the explorations of three Territorial Surveys, one headed by John Wesley Powell, one by Clarence King, and one by Ferdinand V. Hayden. Completion of the Union Pacific Railroad across southern Wyoming 100 years ago, in 1869, materially assisted geologic exploration, and the railheads at Green River and Rock Springs greatly simplified the outfitting of expeditions into the mountains. The overlap of the Powell, King, and Hayden surveys in the Uinta Mountains led to efforts that were less concerted than competitive and not without acrimony. Many parts of the area were seen by all three parties at almost the same time. Duplication was inevitable, of course, but all three surveys contributed vast quantities of new knowledge to the storehouse of geology, and many now-basic concepts arose from their observations. Powell's area of interest extended mainly southward from the Uinta Mountains to the Grand Canyon, including the boundless plateaus and canyons of southern Utah and northern Arizona. King's survey extended eastward from the High Sierra in California to Cheyenne, Wyoming, and encompassed a swath of country more than 100 miles wide. Hayden's explorations covered an immense region of mountains and basins from Yellowstone Park in Wyoming southeast throughout most of Colorado. Powell first entered the Uinta Mountains in the fall of 1868, having traveled north around the east end of the range from the White River country to Green River, Wyoming, then south over a circuitous route to Flaming Gorge and Browns Park, and finally back to the White River, where he spent the winter. In 1869, after reexamining much of the area visited the previous season, Powell embarked on his famous 'first boat trip' down the Green and Colorado Rivers. This trip was more exploratory

  13. Quality management of microfilming projects

    2003-06-01

    Full Text Available I would like to tell you something about my work as quality manager microfilming and about the high quality standards for substitute microfilming we apply within the Dutch preservation programme Metamorfoze. Let me start with going back in time a bit. To be precise, to the year 1870. In this year, William Henry Jackson went riding into the hills of Wyoming, USA. Jackson was the chief photographer for the Hayden expedition. The aim of the Hayden expedition was to record the area as minutely as possible, in order to convince politicians to turn this area into a national park. There were two Hayden expeditions: in 1870 and in 1871. For both of these expeditions William Henry Jackson was the chief photographer. In 1872, the area was indeed proclaimed a national park as a result of the expeditions. And the pictures William Henry Jackson took played an important role in this US government decision. The reason I'm telling you this is not because I want to chat about the beautiful environment of Yellowstone National Park, nor do I want to emphasize the fact that it was quite an achievement that William Henry Jackson was travelling into the Wild West on horseback and coach without breaking the glass negatives he used. It's because I would like to focus your attention on the fact that today we still have access to these photographs made by Jackson and many others of his colleagues from the early days of photography, due to the excellent conditions under which these materials have been kept all this time. Without any doubt, these photographs have an important cultural and historical value.

    Prompts for Restructuring Oral Muscular Phonetic Targets (PROMPT; Hayden, 2004; Hayden, Eigen, Walker, & Olsen, 2010)-a treatment approach for the improvement of speech sound disorders in children-uses tactile-kinesthetic- proprioceptive (TKP) cues to support and shape movements of the oral articulators. No research to date has systematically examined the efficacy of PROMPT for children with childhood apraxia of speech (CAS). Four children (ages 3;6 [years;months] to 4;8), all meeting the American Speech-Language-Hearing Association (2007) criteria for CAS, were treated using PROMPT. All children received 8 weeks of 2 × per week treatment, including at least 4 weeks of full PROMPT treatment that included TKP cues. During the first 4 weeks, 2 of the 4 children received treatment that included all PROMPT components except TKP cues. This design permitted both between-subjects and within-subjects comparisons to evaluate the effect of TKP cues. Gains in treatment were measured by standardized tests and by criterion-referenced measures based on the production of untreated probe words, reflecting change in speech movements and auditory perceptual accuracy. All 4 children made significant gains during treatment, but measures of motor speech control and untreated word probes provided evidence for more gain when TKP cues were included. PROMPT as a whole appears to be effective for treating children with CAS, and the inclusion of TKP cues appears to facilitate greater effect.

    Full Text Available Rauisuchids are large (2–6 m in length, carnivorous, and quadrupedal pseudosuchian archosaurs closely related to crocodylomorphs. Though geographically widespread, fossils of this clade are relatively rare in Late Triassic assemblages. The middle Norian (∼212 Ma Hayden Quarry of northern New Mexico, USA, in the Petrified Forest Member of the Chinle Formation, has yielded isolated postcranial elements and associated skull elements of a new species of rauisuchid. Vivaron haydeni gen. et. sp. nov. is diagnosed by the presence of two posteriorly directed prongs at the posterior end of the maxilla for articulation with the jugal. The holotype maxilla and referred elements are similar to those of the rauisuchid Postosuchus kirkpatricki from the southwestern United States, but V. haydeni shares several maxillary apomorphies (e.g., a distinct dropoff to the antorbital fossa that is not a ridge, a straight ventral margin, and a well defined dental groove with the rauisuchid Teratosaurus suevicus from the Norian of Germany. Despite their geographic separation, this morphological evidence implies a close phylogenetic relationship between V. haydeni and T. suevicus. The morphology preserved in the new Hayden Quarry rauisuchid V. haydeni supports previously proposed and new synapomorphies for nodes within Rauisuchidae. The discovery of Vivaron haydeni reveals an increased range of morphological disparity for rauisuchids from the low-paleolatitude Chinle Formation and a clear biogeographic connection with high paleolatitude Pangea.

  2. Selecting the best defect reduction methodology

    1994-04-01

    Defect rates less than 10 parts per million, unimaginable a few years ago, have become the standard of world-class quality. To reduce defects, companies are aggressively implementing various quality methodologies, such as Statistical Quality Control Motorola`s Six Sigma, or Shingo`s poka-yok. Although each quality methodology reduces defects, selection has been based on an intuitive sense without understanding their relative effectiveness in each application. A missing link in developing superior defect reduction strategies has been a lack of a general defect model that clarifies the unique focus of each method. Toward the goal of efficient defect reduction, we have developed an event tree which addresses a broad spectrum of quality factors and two defect sources, namely, error and variation. The Quality Control Tree (QCT) predictions are more consistent with production experience than obtained by the other methodologies considered independently. The QCT demonstrates that world-class defect rates cannot be achieved through focusing on a single defect source or quality control factor, a common weakness of many methodologies. We have shown that the most efficient defect reduction strategy depend on the relative strengths and weaknesses of each organization. The QCT can help each organization identify the most promising defect reduction opportunities for achieving its goals.

    2015-06-01

    Full Text Available This paper presents the study of a motorcycle frame production line in a particular company in Malaysia. Due to the high demand, the company needs to increase its production by at least 12% compared with current output. In order to improve productivity, the production-floor data was collected and simulated using the discrete event simulation approach. Later, a number of suggestions for improvement were simulated to identify the effect of the suggestions on productivity. In addition, cost analysis was also undertaken to identify the profit margin for a particular period of time for each suggestion. Simulation results indicate that there are three suggestions that are able to fulfill the 12% volume increment. In the short term, the suggestion to hire an assistant line leader will give instant effect to the profit. Meanwhile, for the medium term, Poka-yoke will give higher profit compared with the others, while in the long term, SOP (standard operating procedure implementation will yield a better profit margin. In future, the simulation of a dynamic demand model for this product is suggested to cope with new trends in the market.

    2013-09-01

    Varicella Zoster virus (VZV) productively infects humans causing varicella upon primary infection and herpes zoster upon reactivation from latency in neurons. In vitro studies using cell-associated VZV infection have demonstrated productive VZV-infection, while a few recent studies of human neurons derived from stem cells incubated with cell-free, vaccine-derived VZV did not result in generation of infectious virus. In the present study, 90%-pure human embryonic stem cell-derived neurons were incubated with recombinant cell-free pOka-derived virus made with an improved method or VZV vaccine. We found that cell-free pOka and vOka at higher multiplicities of infection elicited productive infection in neurons followed by spread of infection, cytopathic effect and release of infectious virus into the medium. These results further validate the use of this unlimited source of human neurons for studying unexplored aspects of VZV interaction with neurons such as entry, latency and reactivation.

    2016-02-01

    The instability in today's market and the emerging demands for mass customized products by customers, are driving companies to seek for cost effective and time efficient improvements in their production system and this have led to real pressure for the adaptation of new developmental architecture and operational parameters to remain competitive in the market. Among such developmental architecture adopted, is the integration of lean thinking in the product development process. However, due to lack of clear understanding of the lean performance and its measurements, many companies are unable to implement and fully integrate the lean principle into their product development process and without a proper performance measurement, the performance level of the organizational value stream will be unknown and the specific area of improvement as it relates to the LPD program cannot be tracked. Hence, it will result in poor decision making in the LPD implementation. This paper therefore seeks to present a conceptual model for evaluation of LPD performances by identifying and analysing the core existing LPD enabler (Chief Engineer, Cross-functional teams, Set-based engineering, Poka-yoke (mistakeproofing), Knowledge-based environment, Value-focused planning and development, Top management support, Technology, Supplier integration, Workforce commitment and Continuous improvement culture) for assessing the LPD performance.

    Full Text Available Prihodnja osvetlitev na podlagi polprevodniških virov svetlobe bo spremenila nočno podobo mest. Možnosti njihove umestitve in uporabe v urbanem prostoru so številne. V članku zato proučujemo, ali bi njihova prihodnja uporaba v splošni zunanji razsvetljavi pozitivno vplivala na človekovo sprejemanje tako osvetljenega urbanega prostora. Na podlagi inovativne uporabe omenjenih virov svetlobe smo izoblikovali dva različna koncepta osvetlitve. Prvi koncept temelji na ploskovni osvetlitvi, drugi pa na detajlnem prikazu arhitekturno–urbanih elementov. Predlogi za osvetlitev so bili narejeni na petih različnih lokacijah mesta. Poleg izpolnjevanja funkcionalnih potreb upoštevajo tudi urbanistični in arhitekturni vidik osvetljevanja. Z ocenami afektivne kakovosti slikovnih prikazov smo predstavili in proučevali temeljna afektivna stanja anketiranih. Ugotovitve kažejo, da so se anketiranci pri večini predlogov strinjali pri ocenah spremenljivk »prijetnost« in »pozornost. Statistika pokaže med konceptoma značilne razlike pri ocenah obeh spremenljivk. Pri neposredni primerjavi obeh konceptov smo ugotovili, da je naklonjenost anketirancev do določenega osvetlitvenega koncepta odvisna tudi od mestne lokacije. S člankom želimo poudariti pomen nočne podobe mesta pri razvoju prihodnjih strategij osvetlitve, ki temeljijo na polprevodniških virih svetlobe.

    Full Text Available Prispevek premišljuje emancipatorni potencial gibanj v vstajah 2012–2013, najbolj silovitih v zgodovini samostojne Slovenije. Ne glede na njihovo organizacijsko obliko (iniciativa, kolektiv, neformalno združenje, društvo, zavod, politična stranka …, čas nastanka ali številčnost je v središču predvsem njihovo razumevanje politike in potencial za razvoj strategij za politično delovanje. Pri tem avtorica izhajam iz temeljnega aksioma, da resen premislek o politiki nujno vključuje premislek o temeljni radikalni enakosti med ljudmi, to je politiki emancipacije, ki ji je inherentna egalitarna norma. Analiza temelji na intervjujih s sogovorniki iz 19 gibanj, aktivnih v času vstaj, in pokaže na nasprotja, ki so se vzpostavila med gibanji znotraj paradigme »možnega«, kjer je politika razumljena kot vladavina, in tista na področju »nemožnega«, to je izumljanja prostorov politike, ki bi temeljili na radikalni enakosti onkraj boja za oblast.

    Sandia National Laboratories is responsible for assuring that the US nuclear deterrent remains credible and that the one in a billion disaster of unintended nuclear detonation never occurs. Letting mistake-generated defects into the stockpile would undermine its mission. The current era of shrinking stockpiles is shrinking Sandia`s opportunities to discover and correct mistakes and fine tune processes over long production runs. In response, Sandia has chosen to develop and use a science-based, life cycle systems engineering practices that, in part, require understanding the design to manufacturing issues in enough detail to tune processes and eliminate mistakes before ever making a part. Defect prevention is a key area of concern that currently lacks sufficient theoretical understanding. This report is the result of a scoping study in the application of best-practice quality techniques that could address Sandia`s stockpile mission. The study provides detail on sources and control of mistakes, poka-yoke or mistake-proofing techniques, the Toyota Production system, and design theory in relation to manufacturing quality prediction. Scoping experiments are described and areas for future research are identified.

    Full Text Available The objectives of the research are to identify and prioritize issues that affect the performance of the tire production process, give a number of solutions, and map the value stream of the future (future state mapping. One of the tools used to accurately map the current conditions of the production process in lean manufacturing concept is value stream map/VSM. Another measuring instrument used to increase productivity is the overall equipment effectiveness (OEE, which includes time availability, engine performance and quality. From the three variables, it can be seen that the downtime variable has the largest contribution resulting in low value of the OEE. Based on the OEE data, product time change reached 18,8%, and waiting period contributed as much as 4,9% of the total downtime. To reduce the product change time, SMED method (Single Minutes Exchange Dies is applied at the change of bladder in curing machine, and visual control and poka-yoke applications are also applied to reduce the waiting time. All improvement activities conducted are reflected in the map of the future, including the increase in outputs from the curing machine from 7,814 tires to 8,205 tires per day.Keywords: lean manufacturing, OEE, tire, SMED, map of value chart

    The densities and excess volumes were determined at 298.15 K for the methyl acetate + 1-propanol, methyl acetate + 1-butanol, and ethyl acetate + 1-butanol mixtures. The vapor-liquid equilibria data at 0.3 MPa for these binary systems were obtained using a stainless steel equilibrium still. The activity coefficients were obtained from the experimental data using the Hayden and O’Connell method and the Yen and Woods equation. The binary systems in this study showed positive deviations from ideality. The experimental VLE data were verified with the point-to-point test of van Ness using the Barker routine and the Fredenslund criterion. The different versions of the UNIFAC and the ASOG group contribution models were applied.

    1982-06-01

    The Hot Springs Quadrangle, South Dakota and Nebraska, was evaluated to a depth of 1500 m to identify environments and delineate areas favorable for the occurrence of uranium deposits. The evaluation used criteria developed by the National Uranium Resource Evaluation program. Surface reconnaissance was conducted using a portable scintillometer and a gamma spectrometer. Geochemical sampling was carried out in all geologic environments accessible within the quadrangle. Additional investigations included the followup of aerial radiometric and hydrogeochemical anomalies and a subsurface study. Environments favorable for sandstone-type deposits occur in the Inyan Kara Group and Chadron Member of the White River Group. Environments favorable for marine black-shale deposits occur in the Hayden Member of the Minnelusa Formation. A small area of the Harney Peak Granite is favorable for authigenic deposits. Environments considered unfavorable for uranium deposits are the Precambrian granitic and metasedimentary rocks and Paleozoic, Mesozoic, and Tertiary sedimentary rocks other than those previously mentioned

A characterization of Inclined curves in Euclidean n-space. Comm Fac Sci Univ Ankara, Ser A1 1975;24:15-23]. In this paper, we give some characterizations for a non-degenerate curve α to be a generalized helix by using its harmonic curvatures. Also we define the generalized Darboux vector D of a non-degenerate curve α in n-dimensional Euclidean space E n and we show that the generalized Darboux vector D lies in the kernel of Frenet matrix M(s) if and only if the curve α is a generalized helix in the sense of Hayden.

    Full Text Available Este artigo discute atributos de Os sertões, analisando sua ontologia discursiva, em particular os aspectos ligados às narrativas imaginárias e literárias. Mostra que a principal obra de Euclides conjuga pelo menos dois modos discursivos: o das ciências e um outro que caracteriza as narrativas sobre realidades imaginárias e literárias. Trechos são destacados com o objetivo de demonstrar que na sua construção híbrida participam elementos que poderiam pertencer tanto à ficção como à historiografia. Apoiando-se em Hayden White, o autor contempla três modos interpretativos da história de Canudos em Os sertões: o argumentativo, o explicativo e o ideológico. Finalmente, realiza breve comparação com A guerra do fim do mundo, de Vargas Llosa, quanto ao modo e a seqüência como são narrados os fatos.This analysis of the discursive ontology of Os sertões is particularly concerned with the book’s imaginary and literary narratives. Cunha’s main work combines at least two discursive styles: the discourse of the sciences and the discourse that characterizes narratives dealing with imaginary and literary realities. Selected excerpts show how the hybrid construction of Os sertões relies on elements which may belong to the realm of either fiction or historiography. Based on the ideas of Hayden White, the article detects three ways in which Os sertões interprets the history of Canudos: argumentative, explanatory, and ideological. The text ends with a brief comparison of the narration and sequencing of facts in Vargas Llosa’s La guerra del fin del mundo and Cunha’s Os sertões.

    (Vapor + liquid) equilibrium (VLE) data for three binary mixtures of saturated fatty acids were obtained by differential scanning calorimetry (DSC). However, changes in the calorimeter pressure cell and the use of hermetic pans with holes (phi = 250 mm) in the lids were necessary to make it possible to apply this analytical technique, obtaining accurate results with smaller samples and shorter operational times. The systems evaluated in this study were: myristic acid (C{sub 14:0}) + palmitic acid (C{sub 16:0}), myristic acid (C{sub 14:0}) + stearic acid (C{sub 18:0}), and palmitic acid (C{sub 16:0}) + stearic acid (C{sub 18:0}), all measured at 50 mm Hg and with mole fractions between 0.0 and 1.0 in relation to the most volatile component of each diagram. The fugacity coefficients for the components in the vapor phase were calculated using the Hayden and O'Connell method [J.G. Hayden, J.P. O'Connell, Ind. Eng. Chem. Process Design Develop. 14 (3) (1975) 209-216] and the activity coefficients for the liquid phase were correlated with the traditional g{sup E} models (NRTL [H. Renon, J.M. Prausnitz, Aiche J. 14 (1968) 135-144], UNIQUAC [D.S. Abrams, J.M. Prausnitz, Aiche J. 21 (1975) 116-128], and Wilson [J.M. Prausnitz, N.L. Linchtenthaler, E.G. Azevedo, Molecular Thermodynamics of Fluid-phase Equilibria, River-Prentice Hall, Upper Saddle, 1999]). The sets of parameters were then compared in order to determine which adjustments best represented the VLE.

    The effects of winter recreation—specifically snowmobiling—on wildlife in Yellowstone National Park (YNP) have become high-profile management issues. The road grooming needed to support oversnow travel in YNP is also being examined for its effects on bison (Bison bison) ecology. Data were collected from November 1997 through May 1998 and from December 1998 through May 1999 on the effects of road grooming on bison in Madison–Gibbon–Firehole (MGF) area of YNP Peak bison numbers occurred during late March—early April and were strongly correlated with the snow water equivalent measurements in the Hayden Valley area (1997–1998: r* = 0.62, p:0.001: 1998–1999: r2 = 0.64, P-0.001). Data from an infrared trail monitor on the Mary Mountain trail between the Hayden and Firehole valleys suggest that this trail is the sole corridor for major bison distributional shifts between these locations. Of the 28,293 observations of individual bison made during the study, 8% were traveling and 69% were foraging. These percentages were nearly identical during the period of winter road grooming (7% and 68%, respectively). During this period, 77% of bison foraging activity and 12% of bison traveling activity involved displacing snow. Most travel took place off roads (Pgrooming, with peak use in April and lowest use during the road-grooming period. Bison in the MGF area of YNF neither seek out nor avoid groomed roads. The minimal use of roads compared to off-road areas, the short distances traveled on the roads, the decreased use of roads during the over snow vehicle (OSV) season, and the increased costs of negative interactions with OSVs suggest that grooming roads during winter does not have a major influence on bison ecology.

    Purpose: The objective of this paper is to investigate how environmental improvements can be achieved through operational practices of Lean Manufacturing. Design/methodology/approach: A literature review was conducted to analyze the relationship between operational practices of Lean and reduction of environmental impact in organizational contexts. Verified theoretically, this relationship was observed in a company of the electronics industry, through an exploratory research which contemplated a mixed approach. The adopted research method consisted of a single case study, by providing greater depth and detail of the study. Utilized a research protocol, validated test pilot. The instruments for data collection were semi-structured interviews, direct observation and document analysis. The information was examined qualitatively considering the technique for content analysis. Findings: As a result of the study, it was found that there is evidence for the existence of relationship between the practices of Lean, for example, Kaizen, PDCA (plan, do, check, act), Ishikawa Diagram, Poka-Yoke, Standardized Work and Value Stream Mapping, with the reduction of environmental impacts of an organization. This reduction was observed after application of these practices that resulted in the reduction of energy consumption, water and waste generation. These results were accounted for financially, contributing to a reduction of annual costs by about US$ 20,900. Originality/value: The study presents in detail, the application of operational practices of Lean Manufacturing, with an effective view to reducing the environmental impact and cost reduction. The literature review, a detailed description of the application process and financial results are important information that contributes to the scientific studies that address traditional operating practices and the search for better environmental performance.

Izpolnjevanje določil Direktive o ravnanju z odpadnimi komunalnimi vodami (UWWTD in Direktive o celovitem preprečevanju in omejevanju onesnaževanja (IPPCD bo tudi v Sloveniji zahtevalo znatne investicije. Področje komunalnih voda na operativni ravni ureja občina, država pa mora izpolnjevati prevzete državne obveznosti do EU. Pravočasno doseganje ciljev zahteva koordinacijo aktivnosti, temelječo na strokovnih podlagah. V UWWTD je eden osnovnih parametrov aglomeracija kot zaokroženo območje tako zgoščene poselitve, da zanj veljajo posebna določila in dinamika iz direktive. Merilo zgoščenosti je število prebivalcev na hektar. Za Slovenijo so bili izdelani najprimernejša mreža eno-hektarskih kvadratnih celic in trije tipi celic poselitve. Območje posamezne aglomeracije sestavljajo celice dveh najgostejših tipov poselitve, ki se stikajo. Površina aglomeracij je mnogo manjša od površine naselij iz RPE, zato so skupne slovenske obveznosti iz direktiv manjše, kar pokaže tudi strokovna podlaga za nacionalni program zbiranja in čiščenja odpadnih komunalnih in padavinskih voda. Izdelane aglomeracije so osnovni element načrtovanja in ukrepanja tudi za druga vodnogospodarska načrtovanja (npr. proti poplavni ukrepi, lahko pa si bi jih uporabilo tudi za programe komunalnega opremljanja in druga razvojna načrtovanja v prostoru.

    Full Text Available The Varicella Zoster Virus (VZV is a ubiquitous human alpha-herpesvirus that is the causative agent of chicken pox and shingles. Although an attenuated VZV vaccine (v-Oka has been widely used in children in the United States, chicken pox outbreaks are still seen, and the shingles vaccine only reduces the risk of shingles by 50%. Therefore, VZV still remains an important public health concern. Knowledge of VZV replication and pathogenesis remains limited due to its highly cell-associated nature in cultured cells, the difficulty of generating recombinant viruses, and VZV's almost exclusive tropism for human cells and tissues. In order to circumvent these hurdles, we cloned the entire VZV (p-Oka genome into a bacterial artificial chromosome that included a dual-reporter system (GFP and luciferase reporter genes. We used PCR-based mutagenesis and the homologous recombination system in the E. coli to individually delete each of the genome's 70 unique ORFs. The collection of viral mutants obtained was systematically examined both in MeWo cells and in cultured human fetal skin organ samples. We use our genome-wide deletion library to provide novel functional annotations to 51% of the VZV proteome. We found 44 out of 70 VZV ORFs to be essential for viral replication. Among the 26 non-essential ORF deletion mutants, eight have discernable growth defects in MeWo. Interestingly, four ORFs were found to be required for viral replication in skin organ cultures, but not in MeWo cells, suggesting their potential roles as skin tropism factors. One of the genes (ORF7 has never been described as a skin tropic factor. The global profiling of the VZV genome gives further insights into the replication and pathogenesis of this virus, which can lead to improved prevention and therapy of chicken pox and shingles.

Ankersmit, constitute the most influential trio of current postmodern historiography.We will present in this paper the evolution of Jenkins’ work from what we may call a radical critique of academic historiography to what we consider a real dislike to the form of thinking about the past, as it is conceived, practiced and used nowadays. We divided this article in two sections to accommodate our insight to these two key moments in the development of his theory and his work: the moment of the diffusion of postmodern critique to historiography and the time of the expulsion of the historiography of any emancipated political project.

    On the one hand, the arts are particularly called for in this situation to fill the documentary gaps and silences through acts of experiment and imagination, and they may indeed have a redemptive effect by offering, in Hayden White’s terms, successful ‘emplotments’ of a traumatic past. One the other hand, this redemptive potential simultaneously poses a serious ethical challenge: As Theodor W. Adorno has warned with reference to the Holocaust, it is precisely by making ‘sense’ of human suffering, and by making accessible to the ‘senses’ what is utterly senseless and incomprehensible, that injustice may be done to the victims. In this paper, I will try to illustrate this problematic by looking at two recent films that have attempted to represent the horrors of the middle passage – Steven Spielberg’s canonical Amistad (a terrible failure, in my view, and Guy Deslauriers’ film The Middle Passage [Passage du Milieu]. Based on a script by the Martiniquean novelist and poet Patrick Chamoiseau, the latter example uses an aesthetic approach which may point at a way out of the dilemma outlined above.

  10. The Lessons of the Living Dead: Marcel's Journey from Balbec to Douville-Féterne in Proust's Cities of the Plain: Part Two

    1995-06-01

    Full Text Available By analyzing the narrative of Marcel's journey by the "little train" from Balbec to Douville-Féterne the essay engages with the Proust criticism of Georges Poulet, Paul de Man, and Julia Kristeva to support Hayden White's claim that "it is legitimate to read Proust's narrative as an allegory of figuration itself." Like the Madeleine episode, this one serves as a point from which retrospection and prospection radiate. Central to the discussion is the description of Verdurins' dinner party guests as they stand ready to board the train on the platform at Graincourt: their vivacity, compared to a sort of extinction, suggests a chiasmus between life and death, past and present, experience and reading, and phenomenon and figuration that enriches and integrates Poulet's phenomenological glosses, de Man's rhetorical analysis, and the Kristevan approach to Proust's text. In close proximity to the Verdurins' guests, Marcel is struck chiefly by their remoteness, their pastness, their distance: the figural and phenomenal instability of space and time finally converge in Marcel himself as Proust effects a biblical joke.

We present the cases of two patients with EIB, one with asthma, and one without asthma, who were evaluated at our primary care practice. The first case was a 44-year-old man with a history of seasonal allergic rhinitis but no asthma, who reported difficulty breathing when playing tennis. The second case was a 45-year-old woman who presented with persistent, generally well-controlled asthma, who was now experiencing bouts of coughing and wheezing during exercise. In both cases, an exercise challenge was used to diagnose EIB, and patients were prescribed a short-acting beta agonist to be used immediately before initiating exercise. EIB is a frequently encountered problem among patients presenting to primary care specialists. Affected patients should be made aware of the importance of proactive treatment with a short-acting beta agonist before initiating any exercise.Keywords: asthma, compliance, exercise-induced bronchospasm

    Polybrominated diphenyl ethers (PBDEs) were determined in fish collected from the Gila River, Arizona, a tributary of the Colorado River in the lower part of the Colorado River Basin. Fish samples were collected at sites on the Gila River downstream from Hayden, Phoenix, and Arlington, Arizona in late summer 2003. The Gila River is ephemeral upstream of the Phoenix urban area due to dams and irrigation projects and has limited perennial flow downstream of Phoenix due to wastewater and irrigation return flows. Fifty PBDE congeners were analyzed by high resolution gas chromatography/high resolution mass spectrometry using labeled surrogate standards in composite samples of male and female common carp (Cyrpinus carpio), largemouth bass (Micropterus salmoides) and channel catfish (Ictalurus punctatus). The predominant PBDE congeners detected and quantified were 47, 100, 153, 49, 28, and 17. Concentrations of total PBDEs in these fish ranged from 1.4 to 12700 ng g-1 wet weight, which are some of the highest concentrations reported in fish from the United States. Differences in metabolism of several PBDE congeners by carp is clear at the Phoenix site; congeners with at least one ring of 2,4,5-substitution are preferentially metabolized as are congeners with 2,3,4-substitution.

    Full Text Available From an issue of the Magazine Litteraire featuring the work of Fernand Braudel to an article by Hayden White on the "Absurdist moment" in criticism, it is clear that the disciplines of history and literary studies are converging. Historians like White and Dominick La Capra in the United States, and Michel de Certeau and the members of the Annales School in France are investigating the rhetorical modes of their craft and exploring implications of the fact that it is historians themselves who "make history." At the same time, literary scholars, emerging from Structuralism and the New Criticism, are seeking with increasing urgency to understand the historical dimensions of fiction. By bridging the gap between story and history and by opening lines of dialogue between two traditionally separate. even hostile, fields of inquiry, the essays in this issue of Studies in Twentieth Century Literature provide support for the recent assertion that to raise the question of the historical within literary studies is "the most vital stance to take at this particular moment in history..."

  16. Dynamics of the Yellowstone hydrothermal system

    Hurwitz, Shaul; Lowenstern, Jacob B.

    2014-01-01

    The Yellowstone Plateau Volcanic Field is characterized by extensive seismicity, episodes of uplift and subsidence, and a hydrothermal system that comprises more than 10,000 thermal features, including geysers, fumaroles, mud pots, thermal springs, and hydrothermal explosion craters. The diverse chemical and isotopic compositions of waters and gases derive from mantle, crustal, and meteoric sources and extensive water-gas-rock interaction at variable pressures and temperatures. The thermal features are host to all domains of life that utilize diverse inorganic sources of energy for metabolism. The unique and exceptional features of the hydrothermal system have attracted numerous researchers to Yellowstone beginning with the Washburn and Hayden expeditions in the 1870s. Since a seminal review published a quarter of a century ago, research in many fields has greatly advanced our understanding of the many coupled processes operating in and on the hydrothermal system. Specific advances include more refined geophysical images of the magmatic system, better constraints on the time scale of magmatic processes, characterization of fluid sources and water-rock interactions, quantitative estimates of heat and magmatic volatile fluxes, discovering and quantifying the role of thermophile microorganisms in the geochemical cycle, defining the chronology of hydrothermal explosions and their relation to glacial cycles, defining possible links between hydrothermal activity, deformation, and seismicity; quantifying geyser dynamics; and the discovery of extensive hydrothermal activity in Yellowstone Lake. Discussion of these many advances forms the basis of this review.

    This work deals with the development of a Refuse Derived Fuel (RDF) gasification pilot plant using air as a gasification agent. A downdraft fixed bed reactor is integrated with an Otto cycle Internal Combustion Engine (ICE). Modelling was carried out using the Aspen Plus™ software to predict the ideal operational conditions for maximum efficiency. Thermodynamics package used in the simulation comprised the Non-Random Two-Liquid (NRTL) model and the Hayden-O'Connell (HOC) equation of state. As expected, the results indicated that the Equivalence Ratio (ER) has a direct influence over the gasification temperature and the composition of the Raw Produced Gas (RPG), and effects of ER over the Lower Heating Value (LHV) and Cold Gasification Efficiency (CGE) of the RPG are also discussed. A maximum CGE efficiency of 57-60% was reached for ER values between 0.25 and 0.3, also an average reactor temperature values in the range of 680-700°C, with a peak LHV of 5.8MJ/Nm 3 . RPG was burned in an ICE, reaching an electrical power of 50kW el . The economic assessment of the pilot plant implementation was also performed, showing the project is feasible, with power above 120kW el with an initial investment of approximately US$ 300,000.

    B-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) levels are increased in persons with heart failure (HF); low levels of these peptides rule out HF. We systematically reviewed the literature to assess the use of BNP and NT-proBNP in the diagnosis, prognosis, and treatment for HF. We also examined the biological variation of these peptides in persons with and without HF. We searched Medline, Embase, AMED, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and CINAHL for English-language studies published between January 1989 and June 2012. Supplemental searches involved the gray literature and the reference lists of included studies. Trained reviewers used standardized forms to screen articles for inclusion in the review and to extract data from included papers. We examined the risk of bias with QUADAS-2 for diagnosis studies, the Hayden criteria for prognosis studies, and the Jadad scale for treatment studies. We assessed the strength of evidence in four domains (risk of bias, consistency, directness, and precision) for the diagnosis and treatment studies. Results were reported as narrative syntheses. Additional meta-analyses were conducted for the diagnosis studies. Three hundred ten articles passed through screening and were included in the review. One hundred four articles applied to diagnostic accuracy, 190 papers pertained to prognosis, and nine articles addressed BNP- or NT-proBNP-guided treatment. Each individual paper in this series reports, summarizes, and discusses the evidence regarding diagnosis, prognosis, or treatment.

    At the request of the Pacific Northwest National Laboratory, an in-depth analysis of the rapidly evolving state of real estate investments, high-performance building technology, and interest in efficiency was conducted by HaydenTanner, LLC, for the U.S. Department of Energy (DOE) Building Technologies Program. The analysis objectives were • to evaluate the link between high-performance buildings and their market value • to identify core messaging to motivate owners, investors, financiers, and others in the real estate sector to appropriately value and deploy high-performance strategies and technologies across new and existing buildings • to summarize financial mechanisms that facilitate increased investment in these buildings. To meet these objectives, work consisted of a literature review of relevant writings, examination of existing and emergent financial and policy mechanisms, interviews with industry stakeholders, and an evaluation of the value implications through financial modeling. This report documents the analysis methodology and findings, conclusion and recommendations. Its intent is to support and inform the DOE Building Technologies Program on policy and program planning for the financing of high-performance new buildings and building retrofit projects.

    The trade-off capacity region of a quantum channel characterizes the optimal net rates at which a sender can communicate classical, quantum, and entangled bits to a receiver by exploiting many independent uses of the channel, along with the help of the same resources. Similarly, one can consider a trade-off capacity region when the noiseless resources are public, private, and secret-key bits. We identified [see Wilde, Hayden, and Guha, Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.108.140501 108, 140501 (2012)] these trade-off rate regions for the pure-loss bosonic channel and proved that they are optimal provided that a long-standing minimum-output entropy conjecture is true. Additionally, we showed that the performance gains of a trade-off coding strategy when compared to a time-sharing strategy can be quite significant. In this paper, we provide detailed derivations of the results announced there, and we extend the application of these ideas to thermal-noise and amplifying bosonic channels. We also derive a “rule of thumb” for trade-off coding, which determines how to allocate photons in a coding strategy if a large mean photon number is available at the channel input. Our results on the amplifying bosonic channel also apply to the “Unruh channel” considered in the context of relativistic quantum information theory.

    We will examine three strategies for conveying science effectively to a broad audience: making science relevant, accessible, and intriguing. Through an analysis of the dissemination strategy for three research-related stories at the National Center for Atmospheric Research, we explore methods for successful communication of societally relevant science. We will discuss both time-honored and new means of conveying authentic science in a rapidly changing media landscape. This visualization from the Hayden Planetarium's Journey to the Stars shows the generation of magnetic field in the solar convection zone and its connection to a sunspot at the visible surface of the Sun. Note that the sunspot (with a size slightly larger than Earth) is enlarged for better visibility and not in proper scale relative to the Sun. (© 2009, American Museum of Natural History) New research shows that the Arctic reversed a long-term cooling trend and began warming rapidly in recent decades. The graph shows estimates of Arctic temperatures over the last 2,000 years, based on proxy records, the long-term cooling trend, and the recent warming based on actual observations. A 2000-year transient climate simulation with NCAR's Community Climate System Model shows the same overall temperature decrease as does the proxy temperature reconstruction, which gives scientists confidence that their estimates are accurate.

Despite their success in a controlled setting, relatively few programs are scaled up and implemented in health care systems. Planning for scale-up is a critical, yet often overlooked, element in the process of program design. Equally as important is understanding how to select a program that has already been developed, and adapt and implement the program to meet specific organizational goals. This adaptation and implementation requires attention to organizational goals, available resources, and program cost. We assert that translational behavioral medicine necessitates expanding successful programs beyond a stand-alone research study. This paper describes key factors to consider when selecting, adapting, and sustaining programs for scale-up in large health care systems and applies the Knowledge to Action (KTA Framework to a case study, illustrating knowledge creation and an action cycle of implementation and evaluation activities.

    The American Museum of Natural History's Hayden Planetarium was rebuilt in year 2000 as an immersive theater for scientific data visualization to show the universe in context to our planet. Specific astrophysical movie productions provide the main daily programming, but interactive control software, developed at AMNH allows immersive presentation within a data aggregation of astronomical catalogs called the Digital Universe 3D Atlas. Since 2006, WMS globe browsing capabilities have been built into a software development collaboration with Sweden's Linkoping University (LiU). The resulting Uniview software, now a product of the company SCISS, is operated by about fifty planetariums around that world with ability to network amongst the sites for global presentations. Public presentation of NASA GIBS has allowed authoritative narratives to be presented within the range of data available in context to other sources such as Science on a Sphere, NASA Earth Observatory and Google Earth KML resources. Specifically, the NOAA supported World Views Network conducted a series of presentations across the US that focused on local ecological issues that could then be expanded in the course of presentation to national and global scales of examination. NASA support of for GIBS resources in an easy access multi scale streaming format like WMS has tremendously enabled particularly facile presentations of global monitoring like never before. Global networking of theaters for distributed presentations broadens out the potential for impact of this medium. Archiving and refinement of these presentations has already begun to inform new types of documentary productions that examine pertinent, global interdependency topics.

    There is a rich trove of astronomical phenomena in works of art by artists from the greater New York area, a trend that is even more pronounced in the oeuvres of New York City residents through the present day. A case in point is the trio of oil paintings by artist (and former physics professor) Howard Russell Butler depicting total solar eclipses in 1918, 1923, and 1925 that are based on his own observations. They were long displayed in the former art-deco building of the Hayden Planetarium of the American Museum of Natural History, the location of this conference. (The Museum also has nine other Butler paintings, none of which are currently exhibited.) Since the eclipse paintings have been in storage for many years, these once famous works are now virtually forgotten. Based on our research as an astronomer who has seen sixty-two solar eclipses and an art historian who has written extensively about astronomical imagery, we will discuss Butler's Solar Eclipse Triptych to explore its place in the history of astronomical imaging.

High Alt Med Biol. 18:185-190, 2017.-Exposure to hypoxia is known to induce a reduction in core body temperature as a protective mechanism, which has been shown in both animals and humans. The purpose of this study was to test if acute exposure to normobaric hypoxia (NH) induces anapyrexia in adult humans in association with decreased peripheral oxygen saturation (SpO 2 ). Ten healthy male subjects were seated in atmospheres of normobaric normoxia 21% (NN21), NH 17% (NH17), and 13% (NH13) O 2 for 60 minutes in a counterbalanced manner. Rectal temperature (Tre) was continuously monitored together with the quantification of metabolic heat production (MHP) and body heat storage (S). Baseline physiological measurements showed no differences between the three conditions. SpO 2 was significantly decreased in NH17 and NH13 compared with NN21 (p ≤ 0.001). Tre decreased following 60 minutes of resting in all conditions, but, independent of the conditions, showed no association between Tre and levels of hypoxic SpO 2 . There was also no significant difference in either MHP or S between conditions. The present results showed no evidence of hypoxia-induced anapyrexia in adult humans during 1 hour of resting after exposure to NH either at 13% or 17% O 2 .

    Compression of a message up to the information it carries is key to many tasks involved in classical and quantum information theory. Schumacher [B. Schumacher, Phys. Rev. A 51, 2738 (1995), 10.1103/PhysRevA.51.2738] provided one of the first quantum compression schemes and several more general schemes have been developed ever since [M. Horodecki, J. Oppenheim, and A.

Hayden, and A. Winter, Proc. R. Soc. A 465, 2537 (2009), 10.1098/rspa.2009.0202]. However, the one-shot characterization of these quantum tasks is still under development, and often lacks a direct connection with analogous classical tasks. Here we show a new technique for the compression of quantum messages with the aid of entanglement. We devise a new tool that we call the convex split lemma, which is a coherent quantum analogue of the widely used rejection sampling procedure in classical communication protocols. As a consequence, we exhibit new explicit protocols with tight communication cost for quantum state merging, quantum state splitting, and quantum state redistribution (up to a certain optimization in the latter case). We also present a port-based teleportation scheme which uses a fewer number of ports in the presence of information about input.

    Wilson, William E.

    2010-01-01

    The decade of the 1870s was a time of extensive exploration and surveying in the American West. The nation needed knowledge of the cultural features, topography, natural resources, and geology of this land to promote and aid the 'rapid development of an empire.' The need was particularly acute in the region that still was known in the early 1870s as Colorado Territory. There, cities and towns were springing up along the base of the Front Range, railroads were expanding, and in the mountains prospectors and miners were exploring the countryside seeking and extracting the region's abundant mineral resources. Also, recurring conflicts between the newcomers and Native Americans made it desirable to have accurate maps for military purposes. Four major government-sponsored scientific surveys formed the principal organized effort to provide critical knowledge of the land. Civilian scientists led three of these: John Wesley Powell ('Geographical and Topographical Survey of the Colorado River of the West'); Ferdinand V. Hayden ('Geological and Geographical Survey of the Territories'); and Clarence King ('Geological Exploration of the Fortieth Parallel'). Lt. George Montague Wheeler, a young graduate of West Point (Class of 1866) and a member of the U.S. Army Corps of Engineers, led the fourth and most ambitious project ('United States Geographical Surveys West of the One Hundredth Meridian').

  10. Communication cost of entanglement transformations

    Hayden, Patrick; Winter, Andreas

    2003-01-01

    We study the amount of communication needed for two parties to transform some given joint pure state into another one, either exactly or with some fidelity. Specifically, we present a method to lower bound this communication cost even when the amount of entanglement does not increase. Moreover, the bound applies even if the initial state is supplemented with unlimited entanglement in the form of EPR (Einstein-Podolsky-Rosen) pairs and the communication is allowed to be quantum mechanical. We then apply the method to the determination of the communication cost of asymptotic entanglement concentration and dilution. While concentration is known to require no communication whatsoever, the best known protocol for dilution, discovered by H.-K. Lo and S. Popescu [Phys. Rev. Lett. 83, 1459 (1999)], requires exchange of a number of bits that is of the order of the square root of the number of EPR pairs. Here we prove a matching lower bound of the same asymptotic order, demonstrating the optimality of the Lo-Popescu protocol up to a constant factor and establishing the existence of a fundamental asymmetry between the concentration and dilution tasks. We also discuss states for which the minimal communication cost is proportional to their entanglement, such as the states recently introduced in the context of 'embezzling entanglement' (W. van Dam and P. Hayden, e-print quant-ph/0201041)

    Full Text Available Writing by learners of Japanese as a foreign language often contains words that do not fit the style of their context. One possible reason for this is the lack of information on word connotation and usage labels in existing dictionaries. The present study examines the current state of connotational information and register labels in Japanese learner’s dictionaries, Japanese language dictionaries and dictionaries of synonyms, and proposes a possible technique for analysing the words’ descriptions. The study reveals that Japanese learner’s dictionaries and dictionaries for Japanese native speakers use different register labels and assign them from a different perspective. In the case of synonyms, presenting them in their context of use appears to be more useful than only listing them. Finally, the Balanced Corpus of Contemporary Written Japanese (BCCWJ - Gendai Nihongo Kakikotoba Kinkoo Koopasu is used to show how corpora can be a very important linguistic resource for the analysis of lexical register. ----- Izdelki piscev, ki se učijo japonščino kot tuj jezik, pogosto vsebujejo besede, katerih slog se ne ujema s slogom sobesedila.

    Full Text Available Writing by learners of Japanese as a foreign language often contains words that do not fit the style of their context. One possible reason for this is the lack of information on word connotation and usage labels in existing dictionaries. The present study examines the current state of connotational information and register labels in Japanese learner’s dictionaries, Japanese language dictionaries and dictionaries of synonyms, and proposes a possible technique for analysing the words’ descriptions. The study reveals that Japanese learner’s dictionaries and dictionaries for Japanese native speakers use different register labels and assign them from a different perspective. In the case of synonyms, presenting them in their context of use appears to be more useful than only listing them. Finally, the Balanced Corpus of Contemporary Written Japanese (BCCWJ - Gendai Nihongo Kakikotoba Kinkoo Koopasu is used to show how corpora can be a very important linguistic resource for the analysis of lexical register.-----Izdelki piscev, ki se učijo japonščino kot tuj jezik, pogosto vsebujejo besede, katerih slog se ne ujema s slogom sobesedila. Eden od možnih razlogov za to je pomanjkanje oznak o rabi in informacij o konotacijah besed v obstoječih slovarjih.

  15. Andreev reflections and the quantum physics of black holes

    Manikandan, Sreenath K.; Jordan, Andrew N.

    2017-12-01

    We establish an analogy between superconductor-metal interfaces and the quantum physics of a black hole, using the proximity effect. We show that the metal-superconductor interface can be thought of as an event horizon and Andreev reflection from the interface is analogous to the Hawking radiation in black holes. We describe quantum information transfer in Andreev reflection with a final state projection model similar to the Horowitz-Maldacena model for black hole evaporation. We also propose the Andreev reflection analogue of Hayden and Preskill's description of a black hole final state, where the black hole is described as an information mirror. The analogy between crossed Andreev reflections and Einstein-Rosen bridges is discussed: our proposal gives a precise mechanism for the apparent loss of quantum information in a black hole by the process of nonlocal Andreev reflection, transferring the quantum information through a wormhole and into another universe. Given these established connections, we conjecture that the final quantum state of a black hole is exactly the same as the ground state wave function of the superconductor/superfluid in the Bardeen-Cooper-Schrieffer (BCS) theory of superconductivity; in particular, the infalling matter and the infalling Hawking quanta, described in the Horowitz-Maldacena model, forms a Cooper pairlike singlet state inside the black hole. A black hole evaporating and shrinking in size can be thought of as the analogue of Andreev reflection by a hole where the superconductor loses a Cooper pair. Our model does not suffer from the black hole information problem since Andreev reflection is unitary. We also relate the thermodynamic properties of a black hole to that of a superconductor, and propose an experiment which can demonstrate the negative specific heat feature of black holes in a growing/evaporating condensate.

  16. The status of rheumatoid factor and anti-cyclic citrullinated peptide antibody are not associated with the effect of anti-TNFα agent treatment in patients with rheumatoid arthritis: a meta-analysis.

    Full Text Available OBJECTIVES: This meta-analysis was conducted to investigate whether the status of rheumatoid factor (RF and anti-cyclic citrullinated peptide (anti-CCP antibody are associated with the clinical response to anti-tumor necrosis factor (TNF alpha treatment in rheumatoid arthritis (RA. METHODS: A systemic literature review was performed using the MEDLINE, SCOPUS, Cochrane Library, ISI Web of Knowledge, and Clinical Trials Register databases, and Hayden's criteria of quality assessment for prognostic studies were used to evaluate all of the studies. The correlation between the RF and anti-CCP antibody status with the treatment effect of anti-TNFα agents was analyzed separately using the Mantel Haenszel method. A fixed-effects model was used when there was no significant heterogeneity; otherwise, a random-effects model was applied. Publication bias was assessed using Egger's linear regression and a funnel plot. RESULTS: A total of 14 studies involving 5561 RA patients meeting the inclusion criteria were included. The overall analysis showed that the pooled relative risk for the predictive effects of the RF and anti-CCP antibody status on patient response to anti-TNFα agents was 0.98 (95% CI: 0.91-1.05, p=0.54 and 0.88 (95% CI: 0.76-1.03, p=0.11, respectively, with I(2 values of 43% (p=0.05 and 67% (p<0.01, respectively.

CONCLUSIONS: Neither the RF nor anti-CCP antibody status in RA patients is associated with a clinical response to anti-TNFα treatment.

  17. Rhetoric and History in Brian Friel’s Making History

    Directory of Open Access Journals (Sweden)

    Manfredi Bernardini

    2014-05-01

    Full Text Available This paper proposes an analysis of the rhetorical devices of representation and recording of history, investigated and deconstructed by the so-called "history play" Making History, written by Brian Friel and performed by the Field Day Theatre Company in 1988. The play tells of the heroic deeds of Hugh O’ Neill, a Sixteenth century Ulster gaelic Lord, intertwining his personal facts with the crucial events in Irish History. Friel rediscovers a paradigmatic figure in Irish history, using the theatrical performance in order to dissect and thoroughly scrutinize the basis for the nationalist rhetoric which is at the root of contemporary conflicts in Northern Ireland. Starting from the theoretical contributions of seminal authors such as Hayden White, Paul Ricoeur, Walter Benjamin, Michel De Certeau, the northern Irish playwright challenges the supposedly scientific nature of History, that would decidedly mark it as different from other forms of narrative, such as literature. Hence History’s metalinguistic nature, based on specific rhetorical strategies, is uncovered.  Therefore, on the one hand Friel questions the theoretical foundations of History, of its “grand narratives”,  giving ‘stories’ the chance to be part of official History’s discourse. On the other hand, he lifts the veil on the rhetorical (and in some ways ideological mechanisms involved in the process of History writing, through the character of archbishop Peter Lombard - O’ Neill’s biographer, storyteller and master in elocutio - and sheds light on how History is a form of rhetorical narrative, almost a patchwork of events collected (inventio and assembled (dispositio by the historian according to specific criteria of representation. By taking us inside the very nucleus of the rhetorical devices used by storiography, Friel unmasks the delicate processes of making and unmaking history, the ones that help give birth to identity as well as History.

    IntroductionThe Providence Mountains are in the eastern Mojave Desert about 60 km southeast of Baker, San Bernardino County, California. This range, which is noted for its prominent cliffs of Paleozoic limestone, is part of a northeast-trending belt of mountainous terrain more than 100 km long that also includes the Granite Mountains, Mid Hills, and New York Mountains. Providence Mountains State Recreation Area encompasses part of the range, the remainder of which is within Mojave National Preserve, a large parcel of land administered by the National Park Service. Access to the Providence Mountains is by secondary roads leading south and north from Interstate Highways 15 and 40, respectively, which bound the main part of Mojave National Preserve.The geologic map presented here includes most of Providence Mountains State Recreation Area and land that surrounds it on the north, west, and south. This area covers most of the Fountain Peak 7.5′ quadrangle and small adjacent parts of the Hayden quadrangle to the north, the Columbia Mountain quadrangle to the northeast, and the Colton Well quadrangle to the east. The map area includes representative outcrops of most of the major geologic elements of the Providence Mountains, including gneissic Paleoproterozoic basement rocks, a thick overlying sequence of Neoproterozoic to Triassic sedimentary rocks, Jurassic rhyolite that intrudes and overlies the sedimentary rocks, Jurassic plutons and associated dikes, Miocene volcanic rocks, and a variety of Quaternary surficial deposits derived from local bedrock units. The purpose of the project was to map the area in detail, with primary emphasis on the pre-Quaternary units, to provide an improved stratigraphic, structural, and geochronologic framework for use in land management applications and scientific research.

  1. Mineral Mapping with Imaging Spectroscopy: The Ray Mine, AZ

    1998-01-01

    Mineral maps generated for the Ray Mine, Arizona were analyzed to determine if imaging spectroscopy can provide accurate information for environmental management of active and abandoned mine regions. The Ray Mine, owned by the ASARCO Corporation, covers an area of 5700 acres and is situated in Pinal County, Arizona about 70 miles north of Tucson near Hayden, Arizona. This open-pit mine has been a major source of copper since 1911, producing an estimated 4.5 million tons of copper since its inception. Until 1955 mining was accomplished by underground block caving and shrinkage stope methods. (excavation by working in stepped series usually employed in a vertical or steeply inclined orebody) In 1955, the mine was completely converted to open pit method mining with the bulk of the production from sulfide ore using recovery by concentrating and smelting. Beginning in 1969 a significant production contribution has been from the leaching and solvent extraction-electrowinnowing method of silicate and oxide ores. Published reserves in the deposit as of 1992 are 1.1 billion tons at 0.6 percent copper. The Environmental Protection Agency, in conjunction with ASARCO, and NASA/JPL obtained AVIRIS data over the mine in 1997 as part of the EPA Advanced Measurement Initiative (AMI) (Tom Mace, Principal Investigator). This AVIRIS data set is being used to compare and contrast the accuracy and environmental monitoring capabilities of remote sensing technologies: visible-near-IR imaging spectroscopy, multispectral visible and, near-IR sensors, thermal instruments, and radar platforms. The goal of this effort is to determine if these various technologies provide useful information for envirorunental management of active and abandoned mine sites in the arid western United States. This paper focuses on the analysis of AVIRIS data for assessing the impact of the Ray Mine on Mineral Creek. Mineral Creek flows to the Gila River.

    Compression of a message up to the information it carries is key to many tasks involved in classical and quantum information theory. Schumacher [B. Schumacher, Phys. Rev. A 51, 2738 (1995)PLRAAN1050-294710.1103/PhysRevA.51.2738] provided one of the first quantum compression schemes and several more general schemes have been developed ever since [M. Horodecki, J. Oppenheim, and A. Winter, Commun. Math. Phys. 269, 107 (2007); CMPHAY0010-361610.1007/s00220-006-0118-xI. Devetak and J. Yard, Phys. Rev.

However, the one-shot characterization of these quantum tasks is still under development, and often lacks a direct connection with analogous classical tasks. Here we show a new technique for the compression of quantum messages with the aid of entanglement. We devise a new tool that we call the convex split lemma, which is a coherent quantum analogue of the widely used rejection sampling procedure in classical communication protocols. As a consequence, we exhibit new explicit protocols with tight communication cost for quantum state merging, quantum state splitting, and quantum state redistribution (up to a certain optimization in the latter case). We also present a port-based teleportation scheme which uses a fewer number of ports in the presence of information about input.

    Generation Anthropocene is a student-driven audio podcast series and ongoing project initiated by Michael Osborne, co-produced by Miles Traer, and overseen by Thomas Hayden, all from Stanford University's School of Earth Sciences. The project began as a seminar course where students conducted long-form one-on-one interviews with faculty at Stanford's college radio station, KZSU. Conversation topics covered a range of interdisciplinary issues related to the proposed new geologic boundary delineating "the age of man," including biodiversity loss, historical perceptions of the environment, urban design, agricultural systems, and human-environment interaction. Students researched and selected their own interview subjects, proposed interviewees and questions to the group and solicited critical feedback through small-group work-shopping. Students then prepared interview questionnaires, vetted by the instructors, and conducted in-depth, in-person interviews. Students work-shopped and edited the recorded interviews in a collaborative setting. The format of each interview is conversational, inter-generational, and driven by student interest. In addition to learning areas of academic expertise, advanced interviewing techniques and elements of audio production, the students also explored the diversity of career trajectories in the Earth sciences and allied fields, and the power of human-based stories to communicate complexity and uncertainty for a general audience. The instructors produced the final pieces, and released them online for general public consumption (http://www.stanford.edu/group/anthropocene/cgi-bin/wordpress/). Following the initial release, the Generation Anthropocene podcast series has subsequently been aired weekly at the leading environmental news outlet Grist (grist.org). The program has also expanded to include interviews with non-Stanford subjects, and is currently expanding to other campuses. The Generation Anthropocene program serves as a model for

    The ability to perform multiple, concurrent tasks efficiently is a much-desired cognitive skill, but one that remains elusive due to the brain's inherent information-processing limitations. Multitasking performance can, however, be greatly improved through cognitive training (Van Selst et al., 1999, Dux et al., 2009). Previous studies have examined how patterns of brain activity change following training (for review, see Kelly and Garavan, 2005). Here, in a large-scale human behavioral and imaging study of 100 healthy adults, we tested whether multitasking training benefits, assessed using a standard dual-task paradigm, are associated with variability in brain structure. We found that the volume of the rostral part of the left dorsolateral prefrontal cortex (DLPFC) predicted an individual's response to training. Critically, this association was observed exclusively in a task-specific training group, and not in an active-training control group. Our findings reveal a link between DLPFC structure and an individual's propensity to gain from training on a task that taps the limits of cognitive control. Cognitive "brain" training is a rapidly growing, multibillion dollar industry (Hayden, 2012) that has been touted as the panacea for a variety of disorders that result in cognitive decline. A key process targeted by such training is "cognitive control." Here, we combined an established cognitive control measure, multitasking ability, with structural brain imaging in a sample of 100 participants. Our goal was to determine whether individual differences in brain structure predict the extent to which people derive measurable benefits from a cognitive training regime. Ours is the first study to identify a structural brain marker-volume of left hemisphere dorsolateral prefrontal cortex-associated with the magnitude of multitasking performance benefits induced by training at an individual level.

    Under contract to Pacific Northwest National Laboratory, HaydenTanner, LLC conducted an in-depth analysis of the potential market value of a commercial building energy asset rating program for the U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy. The market research objectives were to: (1) Evaluate market interest and need for a program and tool to offer asset rating and rapidly identify potential energy efficiency measures for the commercial building sector. (2) Identify key input variables and asset rating outputs that would facilitate increased investment in energy efficiency. (3) Assess best practices and lessons learned from existing national and international energy rating programs. (4) Identify core messaging to motivate owners, investors, financiers, and others in the real estate sector to adopt a voluntary asset rating program and, as a consequence, deploy high-performance strategies and technologies across new and existing buildings. (5) Identify leverage factors and incentives that facilitate increased investment in these buildings. To meet these objectives, work consisted of a review of the relevant literature, examination of existing and emergent asset and operational rating systems, interviews with industry stakeholders, and an evaluation of the value implication of an asset label on asset valuation. This report documents the analysis methodology and findings, conclusion, and recommendations. Its intent is to support and inform the DOE Office of Energy Efficiency and Renewable Energy on the market need and potential value impacts of an asset labeling and diagnostic tool to encourage high-performance new buildings and building efficiency retrofit projects.

    2012-08-01

    Full Text Available Upstream open reading frames (uORFs are common in eukaryotic transcripts, but those that encode conserved peptides (CPuORFs occur in less than 1% of transcripts. The peptides encoded by three plant CPuORF families are known to control translation of the downstream ORF in response to a small signal molecule (sucrose, polyamines and phosphocholine. In flowering plants, transcription factors are statistically over-represented among genes that possess CPuORFs, and in general it appeared that many CPuORF genes also had other regulatory functions, though the significance of this suggestion was uncertain (Hayden and Jorgensen, 2007. Five years later the literature provides much more information on the functions of many CPuORF genes. Here we reassess the functions of 27 known CPuORF gene families and find that 22 of these families play a variety of different regulatory roles, from transcriptional control to protein turnover, and from small signal molecules to signal transduction kinases. Clearly then, there is indeed a strong association of CPuORFs with regulatory genes. In addition, 16 of these families play key roles in a variety of different biological processes. Most strikingly, the core sucrose response network includes three different CPuORFs, creating the potential for sophisticated balancing of the network in response to three different molecular inputs. We propose that the function of most CPuORFs is to modulate translation of a downstream major ORF (mORF in response to a signal molecule recognized by the conserved peptide and that because the mORFs of CPuORF genes generally encode regulatory proteins, many of them centrally important in the biology of plants, CPuORFs play key roles in balancing such regulatory networks.

    Making space weather an element of core education is critical for the future of the young field of space weather. Community Coordinated Modeling Center (CCMC) is an interagency partnership established to aid the transition of modern space science models into space weather forecasting while supporting space science research. Additionally, over the past ten years it has established itself as a global space science education resource supporting undergraduate and graduate education and research, and spreading space weather awareness worldwide. A unique combination of assets, capabilities and close ties to the scientific and educational communities enable our small group to serve as a hub for rising generations of young space scientists and engineers. CCMC offers a variety of educational tools and resources publicly available online and providing access to the largest collection of modern space science models developed by the international research community. CCMC has revolutionized the way these simulations are utilized in classrooms settings, student projects, and scientific labs. Every year, this online system serves hundreds of students, educators and researchers worldwide. Another major CCMC asset is an expert space weather prototyping team primarily serving NASA's interplanetary space weather needs. Capitalizing on its unique capabilities and experiences, the team also provides in-depth space weather training to hundreds of students and professionals. One training module offers undergraduates an opportunity to actively engage in real-time space weather monitoring, analysis, forecasting, tools development and research, eventually serving remotely as NASA space weather forecasters. In yet another project, CCMC is collaborating with Hayden Planetarium and Linkoping University on creating a visualization platform for planetariums (and classrooms) to provide simulations of dynamic processes in the large domain stretching from the solar corona to the Earth's upper

    The highly conserved herpesvirus glycoprotein complex gB/gH-gL mediates membrane fusion during virion entry and cell-cell fusion. Varicella-zoster virus (VZV) characteristically forms multinucleated cells, or syncytia, during the infection of human tissues, but little is known about this process. The cytoplasmic domain of VZV gB (gBcyt) has been implicated in cell-cell fusion regulation because a gB[Y881F] substitution causes hyperfusion. gBcyt regulation is necessary for VZV pathogenesis, as the hyperfusogenic mutant gB[Y881F] is severely attenuated in human skin xenografts. In this study, gBcyt-regulated fusion was investigated by comparing melanoma cells infected with wild-type-like VZV or hyperfusogenic mutants. The gB[Y881F] mutant exhibited dramatically accelerated syncytium formation in melanoma cells caused by fusion of infected cells with many uninfected cells, increased cytoskeleton reorganization, and rapid displacement of nuclei to dense central structures compared to pOka using live-cell confocal microscopy. VZV and human transcriptomes were concurrently investigated using whole transcriptome sequencing (RNA-seq) to identify viral and cellular responses induced when gBcyt regulation was disrupted by the gB[Y881F] substitution. The expression of four vital VZV genes, ORF61 and the genes for glycoproteins gC, gE, and gI, was significantly reduced at 36 h postinfection for the hyperfusogenic mutants. Importantly, hierarchical clustering demonstrated an association of differential gene expression with dysregulated gBcyt-mediated fusion. A subset of Ras GTPase genes linked to membrane remodeling were upregulated in cells infected with the hyperfusogenic mutants. These data implicate gBcyt in the regulation of gB fusion function that, if unmodulated, triggers cellular processes leading to hyperfusion that attenuates VZV infection. The highly infectious, human-restricted pathogen varicella-zoster virus (VZV) causes chickenpox and shingles. Postherpetic

    In Acta Astronautica, Vol. 56, No. 5, March 2006, at ISSN0094-5765 there appears the article entitled “Will space actually be the Final Frontier of humankind?” written by Giancarlo Genta, and Michael Rycroft. This Acta Astronautica article requires amplification on the economic side. The writer of this article was personally present at the Apollo 11th launchings for the first landing on the Moon, by Buzz Aldrin and others. The Apollo 11 take off to the Moon, from Cape Carnival, did not leave the situation “so humankind seems forever to be bound to its own planet!” There was nothing pessimistic about the launch of Apollo 11. It is written that there was a lack of vision at that time, which is also not correct. The ‘Final Frontier’ myth was never mentioned on that occasion. At Apollo 11 we did take planet earth's “first faltering step for mankind” on the path towards a space faring civilization, exactly as these two authors later correctly mention. Now with the US Presidential initiatives “Moon, Mars and Beyond,” the authors suggested that it “will depend on social, political and economic issues rather than technological and scientific ones.” This Academy Note respectfully submits that all of these factors social, political and economic issues, plus psychological and scientific ones, instead of, “rather than technical and scientific ones” are going to be the determining factors of the speed of progress of the exploration of the entire universe, and particularly the sun in our Milky Way Galaxy. Russia and Ukraine are now on same, deep-space policy directions. The attention of the readers of this Academy Note is called to the current “Cosmic Collision” excellent presentation at the Hayden Planetarium, located at the Museum of National History in the City of New York. It shows the past, the present and the future of international humankind in exploring space and the creation of the universe, with particular reference to the protons of our

    Highlights: ► Isothermal VLE measurements for DIPE + methanol at T = (305.15, 315.15, and 325.15) K. ► Isothermal VLE measurements for DIPE + ethanol at T = (313.15, 323.15, and 333.15) K. ► Isothermal VLE measurements for DIPE + 1-butanol at T = (318.15, and 338.15) K. ► Data correlated using both the γ–ϕ and ϕ–ϕ approaches. -- Abstract: A glass dynamic recirculating still was employed for the measurement of isothermal (vapour + liquid) equilibrium (VLE) data for the binary mixtures of diisopropyl ether (DIPE) + alcohol, viz. (DIPE + methanol), (DIPE + ethanol), and (DIPE + 1-butanol) at T = (305.15, 315.15, and 325.15) K, T = (313.15, 323.15, and 333.15) K and T = (318.15, and 338.15) K, respectively. The combined standard uncertainties in the reported system pressures, temperatures and phase compositions are ±0.2 kPa, ±0.1 K and ±0.003, respectively. Maximum pressure azeotropes were observed for all isotherms of the (DIPE + methanol) and (DIPE + ethanol) systems. The experimental results were correlated using both the γ–ϕ and ϕ–ϕ approaches. For the correlation of the VLE data with the γ–ϕ approach, the Wilson, NRTL and UNIQUAC G E models with the truncated two-term virial equation of state (Hayden and O’Connell correlation for second virial coefficient computation) were used. In the ϕ–ϕ correlation approach, the Peng–Robinson equation of state was used with the Wong–Sander mixing rules incorporating the same G E models used in the γ–ϕ approach. Comparisons between the experimental values and predictions using UNIFAC (Dortmund) and the Predictive Soave–Redlich–Kwong (PSRK) model were performed to test the predictive capabilities of these models for the experimental data measured here. The thermodynamic consistency of the experimental data was checked with the Herington area test

    The origin of the avian hand, with its reduced and fused carpals and digits, from the five-fingered hands and complex wrists of early dinosaurs represents one of the major transformations of manus morphology among tetrapods. Much attention has been directed to the later part of this transition, from four- to three-fingered taxa. However, earlier anatomical changes may have influenced these later modifications, possibly paving the way for a later frameshift in digit identities. We investigate the five- to four-fingered transition among early dinosaurs, along with changes in carpus morphology. New three-dimensional reconstructions from computed tomography data of the manus of the Triassic and Early Jurassic theropod dinosaurs Coelophysis bauri and Megapnosaurus rhodesiensis are described and compared intra- and interspecifically. Several novel findings emerge from these reconstructions and comparisons, including the first evidence of an ossified centrale and a free intermedium in some C. bauri specimens, as well as confirmation of the presence of a vestigial fifth metacarpal in this taxon. Additionally, a specimen of C. bauri and an unnamed coelophysoid from the Upper Triassic Hayden Quarry, New Mexico, are to our knowledge the only theropods (other than alvarezsaurs and birds) in which all of the distal carpals are completely fused together into a single unit. Several differences between the manus of C. bauri and M. rhodesiensis are also identified. We review the evolution of the archosauromorph manus more broadly in light of these new data, and caution against incorporating carpal characters in phylogenetic analyses of fine-scale relationships of Archosauromorpha, in light of the high degree of observed polymorphism in taxa for which large sample sizes are available, such as the theropod Coelophysis and the sauropodomorph Plateosaurus. We also find that the reduction of the carpus and ultimate loss of the fourth and fifth digits among early dinosaurs did not

    Since 2014, we have produced four "Seismodome" public programs in the Hayden Planetarium at the American Museum of Natural History in New York City. To teach the general public about the dynamics of the Earth, we use a range of seismic data (seismicity catalogs, surface and body wave fields, ambient noise, free oscillations) to generate movies and sounds conveying aspects of the physics of earthquakes and seismic waves. The narrative aims to stretch people's sense of time and scale, starting with 2 billion years of convection, then zooming in seismicity over days to twenty years at different length scales, to hours of global seismic wave propagation, all compressed to minute long movies. To optimize the experience in the planetarium, the 180-degree fisheye screen corresponds directly to the surface of the Earth, such that the audience is inside the planet. The program consists of three main elements (1) Using sonified and animated seismicity catalogs, comparison of several years of earthquakes on different plate boundaries conveys the dramatic differences in their dynamics and the nature of great and "normal" earthquakes. (2) Animations of USArray data (based on "Ground Motion Visualizations" methods from IRIS but in 3D, with added sound) convey the basic observations of seismic wave fields, with which we raise questions about what they tell us about earthquake physics and the Earth's interior structure. (3) Movies of spectral element simulations of global seismic wave fields synchronized with sonified natural data push these questions further, especially when viewed from the interior of the planet. Other elements include (4) sounds of the global ambient noise field coupled to movies of mean ocean wave height (related to the noise source) and (5) three months of free oscillations / normal modes ringing after the Tohoku earthquake. We use and develop a wide range of sonification and animation methods, written mostly in python. Flat-screen versions of these movies

    Though the Late Triassic preserves major paleoenvironmental fluctuations and is key for understanding the evolution of Mesozoic and modern terrestrial ecosystems, comparisons of Late Triassic non-marine sedimentary and fossil records are difficult because global correlations lack precise radioisotopic ages, and have instead been based upon unconstrained biostratigraphic ranges of palynomorph and vertebrate fossils. The Chinle Formation in southwestern North America preserves a major Late Triassic record of paleoenvironmental and biotic change, including significant early dinosaur fossils. Previous high-resolution radioisotopic age constraints for the formation are limited to a single U-Pb zircon age from the upper third of the formation. The extraction of a geologically meaningful age is challenging from these redeposited units and preference is given to considering the youngest age of a deposit as a maximum age and closest approximation of the depositional age. Because calculating a weighted mean age (or median age) from a group of ages from such deposits is often not adequate, the precision of our two new CA-TIMS single crystal zircon U-Pb ages from the Chinle Formation of New Mexico is limited to ca 0.3% (or ± 0.7 Ma) of the youngest crystal age. Our 206Pb/ 238U age of ~ 218 Ma from the Blue Mesa Member in Six Mile Canyon, western New Mexico, demonstrates that strata, palynomorphs, and vertebrate fossils previously considered to be late Carnian in age are actually middle Norian in age. Our new age of ~ 212 Ma from the Hayden Quarry within the Petrified Forest Member at Ghost Ranch, northern New Mexico, provides the first maximum age for important vertebrate assemblages from this area that record the rise of dinosaurs, and demonstrates that basal dinosauromorphs ('dinosaur precursors') co-existed with dinosaurs for at least 18 Ma. These new radioisotopic data allow a new correlation of the Chinle Formation to the Late Triassic timescale, suggesting that most if

    Mexican Americans form the 2nd largest minority group in the US. Fertility is 50% higher than in any other ethnic group. Income levels are inordinately low. In 1970, 42% of Mexican Americans were indigent, making approxiamtely 4200 annually. The Mexican American poor can be categorized into newly arrived aliens or 2nd or 3rd generation American citizens. In the 1st instance, the couple is young and English is not spoken. 2nd or 3rd generation Mexican Americans speak English. The persistent socioeconomic status of the Mexican American relates directly to the level of education. 52% of all Mexican Americans do not finish high school. Paz and Remos described the Mexican in terms of Adler's inferiority model. Murillo stated that to an individual, the family--whether nuclear or extended--is the center of life. The inherent responsibility is that the individual behave properly lest the family be disgraced. The family provides emotional and material security. Familism was seen as a deterrant to utilization of health care services, although some studies claim opposing views. Familism and occupational stability related positively to seeking medical care when ill. Hayden believed that supreme male dominance, individualism, pride, wife beating, aversion to contraceptives, and other characteristics were attributable to machismo. A predominant pattern in Mexican American culture is that of elders' ordering young men and women to establish obedience and male dominance. The husband represents authority and the wife-mother maintains a role of complete devotion to her husband and children. Role differentiation is taught implicitly and explicitly from infancy. Studies on the psychological differences between the sexes indicated that females were oppressed and had lower self esteem than males. 18-24 year old Mexican Americans are becoming less insistent upon strict separation of sex roles and are beginning to reject the traditional Mexican notion of masculine superiority.

    Cenozoic alkaline mafic volcanics of eastern Otago were made famous in classic petrology and petrography texts coauthored by Francis Turner. Several locales have yielded mantle and crustal xenoliths including the Pigroot "mafic phonolite". Here, among abundant spinel lherzolite xenoliths, we discovered an undeformed cumulate gabbro composed of intermediate plagioclase and pargasitic amphibole with augite, ilmenite, magnetite, titanite (sphene) and accessory zircon and apatite. Major and trace elements indicate the rock crystallised from primitive alkaline magma, whereas the mineral assemblage indicates equilibration under amphibolite facies conditions at 5-9 kbar. Accessory mineral U-Pb Ti-Zr thermochronology by LA-ICP-MS on grain separates and in thin section reveals a T-t path that began with zircon crystallisation at 90±2 Ma (^{208}Pb-corrected 206Pb/238U, n=37, mswd=9.9) and 710±20°C (Ti-zircon geothermometer of Watson et al. 2006). Titanite dates (207Pb-corrected 206Pb/238U, n=49) and temperatures (Zr-titanite geothermometer of Hayden et al. 2006 at 7 kbar) form a linear array (r2=0.6) extending from 85 Ma, 830°C to 34 Ma, 760°C. The slope of this T-t array is inconsistent with diffusive loss of Pb and Zr from titanite (Cherniak, pers.comm.) and, together with REE data and reaction textures, indicates prolonged growth at the expense of plagioclase and ilmenite. Apatite U-Pb isotope data projected from the measured 207Pb/206Pb in plagioclase give a lower intercept age of 20±3 Ma (n=17, mswd=1.5) which overlaps the K-Ar age of the phonotephrite host lava (Coombs, pers.comm.). This remarkable xenolith records 1) crystallisation of alkaline mafic magma in the deep crust during early rifting of Zealandia from Gondwana around 90 Ma, 2) heating during continued lithospheric thinning 90-85 Ma, 3) slow cooling (≤2°C/my) for 50 my following continental breakup at 85 Ma, and 4) transport to the surface and thermal quenching at 20 Ma. Slow cooling of the deep

The survey assessed provider demographics, precepting history, learner preferences, and other issues that might affect future decisions about teaching.Results: The response rate was 50% (90 providers. The top reasons for precepting in the past were enjoyment for teaching and personal interaction with learners. The most commonly cited reason for not precepting previously was a perceived lack of time followed by increased productivity demands. When questioned about the future, 65% (59 respondents indicated that they were likely to precept within the next 6 months. A desired reduction in productivity expectations was the most commonly cited motivator, followed by anticipated monetary compensation and adjusted appointment times. A top barrier to future precepting was a belief that teaching decreases productivity and requires large amounts of time.Conclusion: This survey represents an opportunity to study a change in focus for a cohort of busy clinicians who were mostly new to teaching but not new to clinical practice. The survey provides further insight into clinician educators' perceptions regarding the education of a variety of different learners. The results align with data from previous studies in that time

  19. Application of Ti-in-quartz solubility as a thermobarometer in rutile-free rocks

    2011-12-01

    Application of Ti-in-quartz solubility as a thermobarometer (TitaniQ; Thomas et al. 2010) may profoundly influence interpretations of crustal rocks. Complex Ti zoning patterns observed in cathodoluminescence (CL) images of crystals can be associated with changes in P-T conditions that prevailed during quartz crystallization. In rocks lacking rutile application of TitaniQ is challenging because Ti activity (aTiO2) during quartz crystallization must be constrained. Many felsic rocks contain minerals in which Ti is an essential stoichiometric constituent (e.g. ilmenite) that will buffer aTiO2 at a fixed value. To use Ti-in-quartz solubility in rocks lacking rutile (or sphene) the P-T dependencies of Ti-in-quartz solubility must be combined with an independent constraint on either P or T to estimate quartz crystallization conditions. Values for aTiO2 in melts can be calculated using (1) melt compositions and the rutile-saturation model of Hayden et al. (2007), (2) melt compositions and the MELTS algorithms to yield rutile affinity (i.e. degree of saturation) and liquidus T (TL; Ghiorso and Sack, 1995; Asimov and Ghiorso, 1998), and (3) mineral reaction equilibria, such as 2FeTiO3=TiO2+Fe2TiO4, measured mineral compositions, tabulated thermodynamic data, and an input temperature constrained by phase equilibria (or MELTS). The rutile-saturation model was calibrated at 10 kbar only, and intended for applications in which alternatives for calculating aTiO2 are unavailable. This should not be used for quantitative interpretations concerning rocks formed at other pressures because it is likely that Ti solubility in a melt is strongly pressure dependent. Consequently, the 10 kbar rutile-saturation model will underestimate the Ti required for rutile saturation at lower pressures, thereby yielding impossible aTiO2 values that exceed unity. We used a range of published rhyolite melt and Fe-Ti oxide compositions as inputs for aTiO2 calculations using MELTS and mineral reaction

Fair to substantial agreement was observed for the majority of tapering practices measures (κrange=.38-.73; P<.001) except for how training frequency (κ=.26) and the percentage and type of resistance training performed, which changed in the taper (κ=.20). Good to excellent agreement (ICC=.62-.93; P<.05) was observed for items relating to strongman events and traditional exercises performed during the taper. Only the time at which the Farmer's Walk was last performed before competition showed poor reliability (ICC=.27). We have developed a low cost, self-reported, online retrospective questionnaire, which provided stable and reliable answers for most of the demographic, training, and tapering practice questions.

The Big Cottonwood Creek site is downstream from the Hayden Pass Fire burn area, which dramatically altered the hydrology of the watershed and caused this statistically rare (low probability) flood from a statistically common (high probability) storm. The peak flood stage at the cross section closest to the U.S. Highway 50 culvert was 6,438.32 feet (ft) above the North American Datum of 1988 (NAVD 88).The August 29, 2016, flood at the Fountain Creek site had an estimated annual exceedance probability of 0.5505 (return period equal to the 1.8-year flood). The August 29, 2016, flood event was caused by a precipitation event having an annual exceedance probability of 1.0 (return period of 1 year, or the 1-year storm). The peak stage during this flood at the cross section closest to the U.S. Highway 24 bridge was 5,832.89 ft (NAVD 88).Slope-area indirect discharge measurements were carried out at the Big Cottonwood Creek and Fountain Creek sites to estimate peak discharge of the August 23, 2016, flood and August 29, 2016, flood, respectively. The USGS computer program Slope-Area Computation Graphical User Interface was used to compute the peak discharge by adding the surveyed cross sections with Manning roughness coefficient assignments to the high-water marks. The Manning roughness coefficients for each cross section were estimated in the field using the Cowan method.

    Western Pinal County is between Phoenix and Tucson in the Basin and Range physiographic province of southern Arizona and consists of about 2,000 square miles of valley floor with low relief surrounded by mountains. It is the second largest agricultural area in the State, and about 25 percent of the ground water pumped in the State is from this area. The study area has been divided into four parts. Three of these--the Casa Grande-Florence area, the Eloy area, and the Stanfield-Maricopa area--are in the lower Santa Cruz basin; the fourth--the Gila River area--is a long narrow strip along the Gila River from the Ashurst-Hayden Dam to the confluence of the Gila and Santa Cruz Rivers. The project was undertaken to provide a better understanding of the ground-water supply in relation to the present and potential water use in this area of extensive ground-water development. The arid climate of western Pinal County--combining high temperatures and low humidity--causes most of the precipitation to be returned to the atmosphere by evapotranspiration, which leaves only a very small part for recharge to the ground-water reservoir. The computed potential evapotranspiration--44. 97 inches--is five times greater than the average precipitation. In general, the subsurface materials in western Pinal County are unconsolidated alluvial deposits underlain by consolidated alluvium and crystalline rocks and bounded by mountains consisting of crystalline and minor sedimentary rocks. The crystalline and sedimentary rocks of the mountains are not known to be water bearing in western Pinal County. The impermeable rocks underlying the basin are called the hydrologic bedrock unit in this report. Although the unit may consist of several different rock types, the distinction between them is relatively unimportant in this study because none of them yield appreciable amounts of water. The lower Santa Cruz basin in western Pinal County is divided into two sections by a buried ridge of the

    1986 Giotto spacecraft images, revealing a solid cometary nucleus (albeit far blacker than most had predicted), were a dramatic confirmation of Whipple's model -- though in truth few really expected otherwise at the time. In 1942-1946, he led an effort to develop and implement strips of reflective aluminum (i.e., chaff) to confuse enemy radars in World War II. In 1948, he received a certificate of merit for this work from President Harry S. Truman. Eleven years before the launch of the first artificial satellite in 1957, he developed what is now generally termed the Whipple Shield; a thin outer metallic layer stands out from a spacecraft and protects it from high-speed interplanetary dust particles. While particles hitting this outside thin layer would penetrate, they would also vaporize, and in so doing, the resultant debris would disperse and lack the energy to penetrate the main spacecraft skin. This design was used to successfully protect the Stardust spacecraft from cometary dust particles when the spacecraft flew rapidly past comet Tempel 1 in January 2004. He also made significant contributions to fields as diverse as meteor astronomy, satellite tracking, variable stars, supernovae, stellar evolution, astronomical instrumentation and radio astronomy. Along with his colleagues Willy Ley, Wernher von Braun and others, Fred wrote and consulted for a series of very popular articles in Collier's magazine in the early 1950's and these articles, along with earlier lectures at New York's Hayden Planetarium, helped spark the U.S. involvement in space exploration. Of these early beginnings of space exploration, Fred wrote in 1972 "it was no easy task to convince people that man could really go into empty space beyond the Earth's atmosphere, and even beyond the Earth's tenacious gravitational grasp. On looking back over these years, I am still surprised that we succeeded in convincing them." Fred was responsible for initiating the Smithsonian Astrophysical Observatory
