Paper Punch Tape

CERN Multimedia

Physicists coded and recorded their programs through series of holes on punch paper tape or on punched cards. It was popular in the 1970s due to its high throughput speed and low cost, paper tape was one of the original data storage methods for computers. Information was encoded in the distinct pattern of holes punched in the paper; the paper itself was oiled to facilitate being run through the reading mechanism and to prevent tears due to brittleness. Though the paper was cheap, it had low storage capacity (only a few dozen kilobytes per roll) and the machinery involved in punching the holes was quite expensive. Higher capacity alternatives, such as magnetic tape, has get developped.

Trends in gel dosimetry: Preliminary bibliometric overview of active growth areas, research trends and hot topics from Gore’s 1984 paper onwards

International Nuclear Information System (INIS)

Baldock, C

2017-01-01

John Gore’s seminal 1984 paper on gel dosimetry spawned a vibrant research field ranging from fundamental science through to clinical applications. A preliminary bibliometric study was undertaken of the gel dosimetry family of publications inspired by, and resulting from, Gore’s original 1984 paper to determine active growth areas, research trends and hot topics from Gore’s paper up to and including 2016. Themes and trends of the gel dosimetry research field were bibliometrically explored by way of co-occurrence term maps using the titles and abstracts text corpora from the Web of Science database for all relevant papers from 1984 to 2016. Visualisation of similarities was used by way of the VOSviewer visualisation tool to generate cluster maps of gel dosimetry knowledge domains and the associated citation impact of topics within the domains. Heat maps were then generated to assist in the understanding of active growth areas, research trends, and emerging and hot topics in gel dosimetry. (paper)

RF-plasma vapor deposition of siloxane on paper. Part 2: Chemical evolution of paper surface

International Nuclear Information System (INIS)

Sahin, Halil Turgut

2013-01-01

Highlights: ► Investigate the detailed RF-cold plasma surface modified paper by XPS and ATR-FTIR. ► Some chemical analysis of RF-cold plasma surface modified paper after RF plasma treatment. ► Identify the connection between RF plasma treatment and the surface chemistry of paper surface. - Abstract: Survey and high-resolution (HR) XPS studies indicate that OMCTSO plasma treatment created a new silicon containing functional groups and changed the hydroxyl content on the surface of paper. Four intense survey XPS spectrum peaks were observed for the OMCTSO plasma treated paper. They were the Si 2p at 100 eV, Si 2s at 160 eV, C 1s at 285 eV, and O 1s at 525 eV for the plasma modified surface. It was realized that the macromolecular chain-breaking mechanisms and plasma-induced etching processes control the number and the availability of OH-functionalities during OMCTSO plasma exposure on paper. The reaction, initiated by these species, depends mainly on the nature of chemicals in the plasma as well as on the energy level of the plasma and the nature of the surface effects in the modification of the paper. The ATR-FTIR spectrum of paper treated with OMCTSO plasma has characteristic absorption bands attributed to the Si-O and Si-O-Si formations on the surface.

This work describes disposable plasma generators made from metallized paper. The fabricated plasma generators with layered and patterned sheets of paper provide a simple and flexible format for dielectric barrier discharge to create atmospheric plasma without an applied vacuum. The porosity of paper allows gas to permeate its bulk volume and fuel plasma, while plasma-induced forced convection cools the substrate. When electrically driven with oscillating peak-to-peak potentials of ±1 to ±10 kV, the paper-based devices produced both volume and surface plasmas capable of killing microbes. The plasma sanitizers deactivated greater than 99% of Saccharomyces cerevisiae and greater than 99.9% of Escherichia coli cells with 30 s of noncontact treatment. Characterization of plasma generated from the sanitizers revealed a detectable level of UV-C (1.9 nW⋅cm -2 ⋅nm -1 ), modest surface temperature (60 °C with 60 s of activation), and a high level of ozone (13 ppm with 60 s of activation). These results deliver insights into the mechanisms and suitability of paper-based substrates for active antimicrobial sanitization with scalable, flexible sheets. In addition, this work shows how paper-based generators are conformable to curved surfaces, appropriate for kirigami-like "stretchy" structures, compatible with user interfaces, and suitable for sanitization of microbes aerosolized onto a surface. In general, these disposable plasma generators represent progress toward biodegradable devices based on flexible renewable materials, which may impact the future design of protective garments, skin-like sensors for robots or prosthetics, and user interfaces in contaminated environments.

Energy bandwidth studies of U.S. manufacturing sectors can serve as foundational references in framing the range (or bandwidth) of potential energy savings opportunities. This bandwidth study examines energy consumption and potential energy savings opportunities in U.S. pulp and paper manufacturing. The study relies on multiple sources to estimate the energy used in six individual process areas, representing 52% of sector-wide energy consumption. Energy savings opportunities for individual processes are based on technologies currently in use or under development; the potential savings are then extrapolated to estimate sector-wide energy savings opportunity

This paper opens an inquiry into Michelangelo's unusual, yet highly ordered, exercise of the classical vocabulary through a close examination of his 1:1 scaled paper modani. Unlike modani from his contemporaries such as Antonio da Sangallo il Giovane and Bartolomeo Ammannati, Michelangelo's modani...... exhibit no evidence of the use of compass or rule, a realization that has led scholars to conclude that he drew them free-hand. However, new observations reveal that his modani were constructed by means of a deliberate and highly ordered working method linked through cutting and tracing. Although...

Polymer-Derived Ceramic Functionalized MoS2 Composite Paper as a Stable Lithium-Ion Battery Electrode

David, L.; Bhandavat, R.; Barrera, U.; Singh, G.

2015-04-01

A facile process is demonstrated for the synthesis of layered SiCN-MoS2 structure via pyrolysis of polysilazane functionalized MoS2 flakes. The layered morphology and polymer to ceramic transformation on MoS2 surfaces was confirmed by use of electron microscopy and spectroscopic techniques. Tested as thick film electrode in a Li-ion battery half-cell, SiCN-MoS2 showed the classical three-stage reaction with improved cycling stability and capacity retention than neat MoS2. Contribution of conversion reaction of Li/MoS2 system on overall capacity was marginally affected by the presence of SiCN while Li-irreversibility arising from electrolyte decomposition was greatly suppressed. This is understood as one of the reasons for decreased first cycle loss and increased capacity retention. SiCN-MoS2 in the form of self-supporting paper electrode (at 6 mg.cm-2) exhibited even better performance, regaining initial charge capacity of approximately 530 mAh.g-1 when the current density returned to 100 mA.g-1 after continuous cycling at 2400 mA.g-1 (192 mAh.g-1). MoS2 cycled electrode showed mud-cracks and film delamination whereas SiCN-MoS2 electrodes were intact and covered with a uniform solid electrolyte interphase coating. Taken together, our results suggest that molecular level interfacing with precursor-derived SiCN is an effective strategy for suppressing the metal-sulfide/electrolyte degradation reaction at low discharge potentials.

Short- and long-term forecast for chaotic and random systems (50 years after Lorenz's paper)

International Nuclear Information System (INIS)

Bunimovich, Leonid A

2014-01-01

We briefly review a history of the impact of the famous 1963 paper by E Lorenz on hydrodynamics, physics and mathematics communities on both sides of the iron curtain. This paper was an attempt to apply the ideas and methods of dynamical systems theory to the problem of weather forecast. Its major discovery was the phenomenon of chaos in dissipative dynamical systems which makes such forecasts rather problematic, if at all possible. In this connection we present some recent results which demonstrate that both a short-term and a long-term forecast are actually possible for the most chaotic dynamical (as well as for the most random, like IID and Markov chain) systems. Moreover, there is a sharp transition between the time interval where one may use a short-term forecast and the times where a long-term forecast is applicable. Finally we discuss how these findings could be incorporated into the forecast strategy outlined in the Lorenz's paper. (invited article)

Building a comprehensive mill-level database for the Industrial Sectors Integrated Solutions (ISIS) model of the U.S. pulp and paper sector.

Air emissions from the U.S. pulp and paper sector have been federally regulated since 1978; however, regulations are periodically reviewed and revised to improve efficiency and effectiveness of existing emission standards. The Industrial Sectors Integrated Solutions (ISIS) model for the pulp and paper sector is currently under development at the U.S. Environmental Protection Agency (EPA), and can be utilized to facilitate multi-pollutant, sector-based analyses that are performed in conjunction with regulatory development. The model utilizes a multi-sector, multi-product dynamic linear modeling framework that evaluates the economic impact of emission reduction strategies for multiple air pollutants. The ISIS model considers facility-level economic, environmental, and technical parameters, as well as sector-level market data, to estimate the impacts of environmental regulations on the pulp and paper industry. Specifically, the model can be used to estimate U.S. and global market impacts of new or more stringent air regulations, such as impacts on product price, exports and imports, market demands, capital investment, and mill closures. One major challenge to developing a representative model is the need for an extensive amount of data. This article discusses the collection and processing of data for use in the model, as well as the methods used for building the ISIS pulp and paper database that facilitates the required analyses to support the air quality management of the pulp and paper sector.

Increasing number of authors per paper in Korean science and technology papers

Full Text Available We examined changes in the number of authors per paper for science and technology papers (agricultural sciences, engineering and technologies, medical sciences, and natural sciences in Korea. We employed the Scopus database to examine the change in the number of authors in papers, which were published from 2000 to 2015 in the 234 Korean academic journals indexed on Scopus. We found that the global trend of growth in the number of authors per paper is evident in Korea as well. While there was little evidence of a correlation with the citation per paper, a positive correlation was found between with the field-weighted citation impact, another measure of a paper’s impact, in medical and natural science papers. In terms of the type of collaboration, we found that international collaboration papers had the highest number of authors, followed by national and institutional collaborations. The number of authors per paper was highest for those published in the top 10% journals by Source Normalized Impact per Paper, followed by Scopus-indexed journals, while papers published in Korea Citation Index had the lowest number of authors per paper. We propose that the rise in the number of authors per paper in Korean papers may be ascribed to many Korean research programs encouraging group research and the widespread availability of the internet, which has stimulated joint research efforts and encouraged international collaboration.

Brazil’s Generous Diplomacy: Friendly Dragon or Paper Tiger?

Robert Muggah

Full Text Available Featuring a stable democracy and dizzying economic growth, Brazil is fast on the way to acquiring global power status. The country is investing in enhanced multilateral and bilateral relationships as a means of leveraging trade and reducing vulnerability abroad and on the domestic front. This chapter demonstrates how Brazil has increasingly aligned its foreign policy with a ‘South–South Cooperation’ (SSC agenda as a means of achieving these parallel objectives. But while Brazil’s trade activities have received attention, there has been comparatively less focus on the country’s aid policy and practice.Moreover, there is surprisingly little discussion of how the country’s foreign policy pillars – trade and aid – are explicitly linked. The chapter demonstrates how Brazil’s emerging aid agenda is fundamentally informed by trade considerations. Over the past decade Brazil has positioned its foreign policy agenda in such a way as to re-shape the global terms of trade in its favour and decrease its dependency both internationally and domestically.Brazil’s relatively modest development aid allocations are amplified by a wider effort to advance trade, foreign direct investment and technology transfer. Brazil seeks to expand to new markets for its products, services and investment, it anticipates that its South–South Development Cooperation (SSDC stance will facilitate the extension of its influence in bilateral and multilateral arrangements, including the World Trade Organization (WTO and the United Nations Security Council.

The first papers reporting original research results in technical periodicals and proceedings appeared in the late 17th century. Since that time, the typical scientific paper has evolved from a fairly simple document, accessible to a general audience, to a much more complex one, aimed at a specialized audience. The purpose of this article is to give an overview of what the first scientific papers were like and how they evolved to their present form and style. To facilitate this discussion, the scientific paper`s development has arbitrarily been divided into four stages: the origin and formative years of the scientific paper (1665-1765), emergence of scientific papers written for specialized publications (1765-1865), development of the modem scientific paper (1865-1965), and hyperspecialization and computerization of the modem scientific paper (1965-?).

PaperBLAST: Text Mining Papers for Information about Homologs

Large-scale genome sequencing has identified millions of protein-coding genes whose function is unknown. Many of these proteins are similar to characterized proteins from other organisms, but much of this information is missing from annotation databases and is hidden in the scientific literature. To make this information accessible, PaperBLAST uses EuropePMC to search the full text of scientific articles for references to genes. PaperBLAST also takes advantage of curated resources (Swiss-Prot, GeneRIF, and EcoCyc) that link protein sequences to scientific articles. PaperBLAST’s database includes over 700,000 scientific articles that mention over 400,000 different proteins. Given a protein of interest, PaperBLAST quickly finds similar proteins that are discussed in the literature and presents snippets of text from relevant articles or from the curators. With the recent explosion of genome sequencing data, there are now millions of uncharacterized proteins. If a scientist becomes interested in one of these proteins, it can be very difficult to find information as to its likely function. Often a protein whose sequence is similar, and which is likely to have a similar function, has been studied already, but this information is not available in any database. To help find articles about similar proteins, PaperBLAST searches the full text of scientific articles for protein identifiers or gene identifiers, and it links these articles to protein sequences. Then, given a protein of interest, it can quickly find similar proteins in its database by using standard software (BLAST), and it can show snippets of text from relevant papers. We hope that PaperBLAST will make it easier for biologists to predict proteins’ functions.

2015-04-01

Full Text Available Recent studies of fast growing species grown in PT. Sari Bumi Kusuma, Central Kalimantan, show that based on their fiber dimensions there are five species, namely Endospermum diadenum, Dillenia spp., Adinandra dumosa, Adiandra sp., and Nauclea junghuhnii with good potential for pulp and paper production. The fiber length of those five wood species are was more than 2,200 µm on average. This paper studies the physical properties, fiber dimensions and their chemical contents to predict the paper and pulp quality. The result shows that all of the species were classified in the medium to high density category. All species were classified into the first class quality for pulp and paper. Based on chemical contents, Dillenia sp. is the most suitable species due to its high value of holocellulose and a-cellulose, low lignin content, and its fiber length is about 3,119 µm on average. A. dumosa also has good opportunities because it had the longest fiber lengths (3,137 µm on average and high value of holocellulose, even though it has the highest lignin content. While Nuclea junghuhnii is less suitable due to low values of holocellulose and a-cellulose.

An Attempt at Reconstruction of the Original Colour Scheme of the Paper Ground of Witkacy’s Portraits

Full Text Available In the years 2005–2006 at a Restoration Workshop of Muzeum Pomorza Środkowego [Museum of Central Pomerania] in Słupsk, Witkacy’s portraits were framed in a new passe partout and glass pane. Based on the photographs taken then of fragments on which the colour of the paper ground was preserved, a computer reconstruction of the original colour of the paper was made. Comparison of the portraits with their probable original versions allows to risk a claim that nowadays we have to do with totally different pictures. The colour of the paper has changed considerably, e.g. from its initial violet it has turned into grey-beige. Equally big changes can be observed between the reverse and the face. When framing the portrait, restorers found an unfinished portrait on the reverse. The examples presented in this work show how important for the knowledge of the artist and his work is drawing attention to a single work of art, which is best to study directly and not through its reproductions or studies on it.

Aspects on McCallin’s paper, “Grappling with the literature in a grounded theory study”

Full Text Available I read Antoinette McCallin’s paper with interest and I have learned that there are problems which I have foreseen perhaps because I am, as many medical doctors are, unaware of the many “theories” or different perspectives that one can chose in undertaking a study. Kirsti Malterud, Professor of General Practice in Bergen, Norway, used to say that we are theoretically ignorant and instead focus on the pragmatic issues of how to survive the day and help the “sick” in an appropriate way. However, even if I feel like a real novice, I have some remarks about literature and grounded theory studies.A literature review as part of, for instance, a research proposal and one that is undertaken when actually performing a grounded theory study are two different issues in my opinion. When writing a research proposal or an application for research funding, the issue is (which I personally learned the hard way…. to follow the rules of the committees or funding agencies whether or not the review demanded is appropriate for what you plan to study. Here the discussion in the first part of McCallin’s paper is appropriate because when you write a research proposal or the like perhaps (although not necessarily a discussion is needed of the different “GT methods”, their requirements, historical development, different opinions among researchers and so on as well as why you have chosen a particular approach.

Trends in Multi-authored Papers in Economics

OpenAIRE

John Hudson

1996-01-01

This paper looks at the growth of multiple-authored papers in eight leading economics journals. In 1950, multiple authorship was a relative rarity. By the 1990s, it had become commonplace. An empirical analysis suggests that this growth has not been even over time but appears to have been greatest in the mid-1960s and again since the mid-1970s. Possible reasons for this growth include developments in computer technology. Its implications for the economics profession are briefly discussed.

Highlights: ► Using crop straws and wood wastes for paper production should be promoted. ► Bagasse and textile waste recycling should be properly limited. ► Imports of scrap paper should be encouraged. ► Sensitivity analysis, uncertainties and policy implications are discussed. - Abstract: Waste recycling for paper production is an important component of waste management. This study constructs a physical input–output life-cycle assessment (PIO-LCA) model. The PIO-LCA model is used to investigate environmental impacts of four categories of waste recycling in China’s paper industry: crop straws, bagasse, textile wastes and scrap paper. Crop straw recycling and wood utilization for paper production have small total intensity of environmental impacts. Moreover, environmental impacts reduction of crop straw recycling and wood utilization benefits the most from technology development. Thus, using crop straws and wood (including wood wastes) for paper production should be promoted. Technology development has small effects on environmental impacts reduction of bagasse recycling, textile waste recycling and scrap paper recycling. In addition, bagasse recycling and textile waste recycling have big total intensity of environmental impacts. Thus, the development of bagasse recycling and textile waste recycling should be properly limited. Other pathways for reusing bagasse and textile wastes should be explored and evaluated. Moreover, imports of scrap paper should be encouraged to reduce large indirect impacts of scrap paper recycling on domestic environment.

Hand D and Shakespeare’s Unorthodox Literary Paper Trail

Directory of Open Access Journals (Sweden)

Diana Price

2016-03-01

Full Text Available The biography of William Shakespeare exerts an influence on various areas of research related to Shakespeare, including textual, bibliographical, and attribution studies. A case in point is the theory that Shakespeare wrote the Hand D Additions in the Sir Thomas More manuscript. That theory is now part of received scholarship, even though many of the assumptions and arguments first published in 1923 have been challenged. The original palaeographic argument can be reappraised with reference to the criteria and procedures of the forensic document examiner. Recent scholarship relevant to an investigation of the case that the Hand D Additions are Shakespeare’s ‘foul papers’, including Paul Werstine’s Early Modern Playhouse Manuscripts and the Editing of Shakespeare, provides the foundation for a brief reconsideration of that topic. Supporting arguments for the Hand D attribution, in particular those based on orthography, prove vulnerable to challenge.

Ozone and UV radiation are aggressive advanced oxidation processes that have been tested to degrade paper mill effluents. Eugenol and guaiacol, models of the lignin fraction of these wastewaters are easily oxidisable by ozone even at low dosages (0.8 g/h). On the other hand, glucose and fatty acids are more difficult to degrade, although the combination O{sub 3}/UV improves the process and important decrease in COD and BOD values were observed. Solar photocatalysis is a milder alternative to O{sub 3}/UV; photo-Fenton reaction and titanium dioxide have been tested. Both methods have been able to degrade the phenolic components of paper wastewaters, but they were not able to oxidise glucose or volatile fatty acids. (orig.)

This white paper presents the rationale for developing a community-wide capability for whole-device modeling, and advocates for an effort with the expectation of persistence: a long-term programmatic commitment, and support for community efforts. Statement of 2030 goal (two suggestions): (a) Robust integrated simulation tools to aid real-time experimental discharges and reactor designs by employing a hierarchy in fidelity of physics models. (b) To produce by the early 2030s a capability for validated, predictive simulation via integration of a suite of physics models from moderate through high fidelity, to understand and plan full plasma discharges, aid in data interpretation, carry out discovery science, and optimize future machine designs. We can achieve this goal via a focused effort to extend current scientific capabilities and rigorously integrate simulations of disparate physics into a comprehensive set of workflows.

An inkjet-printed, fully passive sensor capable of either humidity or gas sensing is presented herein. The sensor is composed of an interdigitated electrode, a customized printable gas sensitive ink and a specialized dipole antenna for wireless sensing. The interdigitated electrode printed on a paper substrate provides the base conductivity that varies during the sensing process. Aided by the porous nature of the substrate, a change in relative humidity from 18% to 88% decreases the electrode resistance from a few Mega-ohms to the kilo-ohm range. For gas sensing, an additional copper acetate-based customized ink is printed on top of the electrode, which, upon reaction with hydrogen sulphide gas (H2S) changes, both the optical and the electrical properties of the electrode. A fast response time of 3 min is achieved at room temperature for a H2S concentration of 10 ppm at a relative humidity (RH) of 45%. The passive wireless sensing is enabled through an antenna in which the inner loop takes care of conductivity changes in the 4–5 GHz band, whereas the outer-dipole arm is used for chipless identification in the 2–3 GHz band.

Full Text Available Among three sections that follow the Paper-Based TOEFL (PBT, many test takers find listening comprehension section is the most difficult. Thus, in this research the researcher aims to explore how students learn PBT’s listening comprehension section effectively through song technique. This sounds like a more interesting and engaging way to learn language because music is a very powerful motivational tool for learning language. To reach the goal of this study, the researcher applied the grammar approach. It is an appropriate approach since the main idea of grammar-based listening exercises is to analyze the language by its components and reconstruct an incomplete text. Besides, the researcher employed an English song as the media the researcher uses the top- down model for the Listening Process.  In this research, the writer tries to share his experience in teaching listening in English department of Teknokrat College by implementing song technique.

1981-06-01

The report deals with measurements of the energy consumption in order to optimize the operation of the Beloit paper-making machine at Sande Paper Mill A/S (Norway). The machine was built in 1962, and a heat recovery system is connected. Before regulating the working condition, the energy consumption was calculated to be 3220 KJ/kg evaporated water. The dewpoint was on this occasion 51.1oC and the water content 0.080 kg water/kg dry air. By regulating the quantity of wet air, the energy consumption decreased to 3060 KJ/kg. The dewpoint was 60.1oC, and the water content 0.140 kg/kg. The reduction of the energy consumption was calculated to be 6%. But some uncomfort related to the personnel in the machine hall was observed. By reducing the dewpoint to 57oC, no problems occurred. The specific energy consumption was 3160 KJ/kg and a reduction of 2% was achieved. The heat loss in condenser was measured to be 5%. 14 drawings, 11 table.

The BaBar drift chamber (DCH) is used to measure the properties of charged particles created from e + e - collisions in the PEP-II asymmetric-energy storage rings by making precise measurements of position, momentum and ionization energy loss (dE/dx). In October of 2005, the PEP-II storage rings operated with a luminosity of 10 x 10 33 cm -2 s -1 ; the goal for 2007 is a luminosity of 20 x 10 33 cm -2 s -1 , which will increase the readout dead time, causing uncertainty in drift chamber measurements to become more significant in physics results. The research described in this paper aims to reduce position and dE/dx uncertainties by improving our understanding of the BaBar drift chamber performance. A simulation program --called garfield--is used to model the behavior of the drift chamber with adjustable parameters such as gas mixture, wire diameter, voltage, and magnetic field. By exploring the simulation options offered in garfield, we successfully produced a simulation model of the BaBar drift chamber. We compared the time-to-distance calibration from BaBar to that calculated by garfield to validate our model as well as check for discrepancies between the simulated and calibrated time-to-distance functions, and found that for a 0 o entrance angle there is a very good match between calibrations, but at an entrance angle of 90 o the calibration breaks down. Using this model, we also systematically varied the gas mixture to find one that would optimize chamber operation, which showed that the gas mixture of 80:20 Helium:isobutane is a good operating point, though more calculations need to be done to confirm that it is the optimal mixture

Full Text Available The scientific knowledge is disseminated by research papers. Most of the research literature is copyrighted by publishers and avail- able only through paywalls. Recently, some websites offer most of the recent content for free. One of them is the controversial website Sci-Hub that enables access to more than 47 million pirated research papers. In April 2016, Science Magazine published an article on Sci-Hub activity over the period of six months and publicly released the Sci-Hub’s server log data. The mentioned paper aggregates the view that relies on all downloads and for all fields of study, but these findings might be hiding interesting patterns within computer science. The mentioned Sci-Hub log data was used in this paper to analyse downloads of computer science papers based on DBLP’s list of computer science publications. The top downloads of computer science papers were analysed, together with the geographical location of Sci-Hub users, the most downloaded publishers, types of papers downloaded, and downloads of computer science papers per publication year. The results of this research can be used to improve legal access to the most relevant scientific repositories or journals for the computer science field.

The Brazilian paper industry has competitive advantages offered by the favorable climate, which favors an increase in the yield of forest restoration, and consequently, in the productive process. On the other hand, following the greenhouse gases (GHG), we can see our constantly changing sun, causing the solar storms, allowing their prevention or mitigating measures. The objective of this work is to contribute to the construction of the understanding necessary for the reduction of GHG emission from a preliminary analysis of the pulp and paper sector. As a secondary objective, the text preliminarily analyzes a company’s behavior against the backdrop of the Paris Accord, which strengthens the global response to the threat of climate change and strengthens the capacity of countries to deal with the impacts of such changes. The identification of best practices in the pulp and paper industry is understood, focusing on environmental sustainability, such as the adoption of reforestation, obtaining significant results. In the case of the paper industry, the management of public forests for sustainable production, within the structure of the Ministry of the Environment, establishes the promotion of public awareness about the importance of conservation, recovery and sustainable management of forest resources.

Books and documents attacked by fungi and insects have already been treated by radiation for disinfestations purposes. However, there is still need to investigate the influence of radiation on the cellulose paper structure. The aim of this research was to study the effects of radiation on paper properties, especially those related to strength and appearance. Paper sheets for this study were prepared in the laboratory, using bleached eucalyptus pulp as raw material. No additives were used to concentrate the attention only on the effects of irradiation on the pure cellulose matrix. The samples were irradiated at IPEN's 60 Co Gammacell irradiator with six radiation doses, from 3 to 15 kGy at the dose rate 0.817 Gy/s. The properties of paper sheets were tested after irradiation and compared with unirradiated samples according to ISO methods. No significant changes were detected in paper samples irradiated up to 15 kGy.

The next generation(s) of Europeans facing nuclear weapons: forgetful, indifferent but supportive? EU Non-Proliferation Consortium, Non-Proliferation Papers No. 56 March 2017

International Nuclear Information System (INIS)

Pelopidas, Benoit

2017-04-01

The post-cold war generation of citizens is forgetting nuclear weapon-related dangers and becoming indifferent to the issue. At the same time, the absence of mass grassroots, anti-nuclear protest suggests tacit support for current nuclear weapon policies. These three common diagnoses are potentially contradictory and, more importantly, are only assumptions. This paper is the first systematic attempt at assessing the attitude of the under 30's generation of European Union (EU) citizens with regard to nuclear weapons. It is based on a poll of over 10 000 citizens across the 28 EU member countries. The paper finds that none of these assumptions holds. Except for the cases of near nuclear use, the lack of knowledge about nuclear danger is not that widespread; it only increases slowly and not uniformly. Similarly, the lack of popular engagement in the nuclear weapon debate does not mean support for existing policies. In this paper, the sentiment of support is assessed with a set of three criteria: the feeling of safety attained from nuclear weapons; satisfaction with policies taken in one's name; and acceptance of vulnerabilities arising from the possession of nuclear weapons. This paper finds that overall support in these areas is below 30 per cent in every country for which there was a representative sample of respondents. Neither do the youth express a lack of concern, but rather a strong feeling of inability to affect the outcome. This suggests the need for both a research agenda and a reform of EU educational policies aimed at this generation on nuclear weapons

Paper is ubiquitous in everyday life and a truly low-cost substrate. The use of paper substrates could be extended even further, if electronic applications would be applied next to or below the printed graphics. However, applying electronics on paper is challenging. The paper surface is not only very rough compared to plastics, but is also porous. While this is detrimental for most electronic devices manufactured directly onto paper substrates, there are also approaches that are compatible with the rough and absorptive paper surface. In this review, recent advances and possibilities of these approaches are evaluated and the limitations of paper electronics are discussed. Copyright © 2011 WILEY-VCH Verlag GmbH & Co.

2012-06-01

Full Text Available While much of the developed world struggles with debt and chronically low growth, Canada, one of the best-performing members of the G-7, remains on firmer footing. However, this country still has to cope with slower growth, cutbacks and aging infrastructure. As this paper argues, reconciling these facts will take creative, non-partisan problem solving, and it is time governments got to work. Particularly brave politicians might consider charging the public the full costs of infrastructure use in the form of a tax. For the less daring, advances in robotics and data management offer substantial efficiency gains. Whichever path Canadian governments choose, they will not travel it alone. The burgeoning power of social media will amplify citizens’ voices and involvement. However, private sector expertise and capital could be just what is needed to ease Canada’s looming infrastructure woes, notably in the form of infrastructure banks (iBanks; cost-effective, streamlined replacements for the tangled mass of programs and departments that currently build, manage and maintain public infrastructure. Such an institution could allow private investment vehicles like bonds, preference shares and mortgage-backed securities to be issued to create capital and to pay back investors as the objects of its investments repaid the capital borrowed. iBanks could raise tricky problems about overlapping jurisdictions and would, in some parts of the country, be a tough sell, but Canada has been lagging badly in transportation innovation and must consider unorthodox solutions.

Radioactivity in newspapers and information business papers

1997-01-01

The radioactivities of the naturally occurring radionuclides ( 226 Ra, 228 Ra, 228 Th and 40 K) and a fallout nuclide ( 137 Cs) in newspapers issued during 1990s in Japan and information business papers were determined by gamma-ray spectrometry to obtain information on radioactivity level of papers and the sources of radionuclides contained in papers. The concentrations of the naturally occurring radionuclides in the newspapers were low, whereas the 228 Ra and 228 Th contents of an information business paper were as high as 30 Bq kg -1 . Perhaps the thorium series nuclides contained in this information business paper was present in the kaolinite filler used in the paper. 137 Cs was detected in all the newspapers, while the radionuclide was not detected in the information business papers. The 137 Cs concentration in the newspaper ranged from 0.1 to 0.2 Bq kg -1 . Mechanical pulp was the main constituent of the newspapers, and 137 Cs in the newspapers was maybe brought with the mechanical pulp which kept a part of fallout 137 Cs contained in the material wood. The data obtained in this work may be useful to estimate radioactivity released from incinerators to the environment by burning waste paper. (author)

Full Text Available Bisphenol A (BPA is a chemical substance which is produced in great quantities globally and of which serious negative effects on endocrine system are suspected. It’s a commonly used color developer in thermal paper. BPA used for this purpose is in free, unbound form and one of the potential sources for BPA exposure of humans. In this study, 12 thermal paper receipt samples were collected from various workplaces selected randomly and analyzed. BPA was determined in all samples. Average value of high BPA concentrations obtained from 10 samples was found as 13.83 mg BPA/g paper. At the same time, low values being 0.40 mg BPA/g paper and 0.11 mg BPA/g paper respectively were found in two samples as compared to others.

Li Lanyan; Xia Keqiang; Li Liang; Shang Songmin; Guo Qingzhong; Yan Guoping

2012-01-01

Flexible polypyrrole/graphene oxide (GO) nanocomposite paper was prepared via a facile and one-step chemical oxidation polymerization method. The morphology and microstructure of the obtained papers were characterized by SEM, FTIR, and XRD. GO was confirmed experimentally to be exfoliated and uniformly dispersed in the resulting nanocomposites. The specific capacitance value of the nanocomposite paper has been determined to be about 330 F/g at a scan rate of 100 mV/s, suggesting the possible application of the nanocomposite as a supercapacitor electrode. After 700 cycles at a scan rate of 100 mV/s, only 9 % decrease in specific capacitance as compared to initial value indicates the superior electrochemical cyclic stability of the nanocomposite paper.

Universal industrial sectors integrated solutions module for the pulp and paper industry.

Science.gov (United States)

Bhander, Gurbakhash; Jozewicz, Wojciech

2017-09-01

The U.S. is the world's second-leading producer of pulp and paper products after China. Boilers, recovery furnaces, and lime kilns are the dominant sources of emissions from pulp and paper mills, collectively accounting for more than 99 % of the SO 2 , almost 96 % of the NO X , and more than 85 % of the particulate matter (PM) emitted to the air from this sector in the U.S. The process of developing industrial strategies for managing emissions can be made efficient, and the resulting strategies more cost-effective, through the application of modeling that accounts for relevant technical, environmental and economic factors. Accordingly, the United States Environmental Protection Agency is developing the Universal Industrial Sectors Integrated Solutions module for the Pulp and Paper Industry (UISIS-PNP). It can be applied to evaluate emissions and economic performance of pulp and paper mills separately under user-defined pollution control strategies. In this paper, we discuss the UISIS-PNP module, the pulp and paper market and associated air emissions from the pulp and paper sector. After illustrating the sector-based multi-product modeling structure, a hypothetical example is presented to show the engineering and economic considerations involved in the emission-reduction modeling of the pulp and paper sector in the U.S.

Highlights: • A facile and economical method to fabricate interlayer for high-performance lithium-sulfur battery was demonstrated. • The performance of lithium-sulfur batteries without and with interlayer was compared. • The mechanism for the function of interlayer was explained. - Abstract: One of the several challenging problems hampering lithium-sulfur (Li-S) battery development is the so-called shuttling effect of the highly soluble intermediates (Li_2S_8–Li_2S_6). Using an interlayer inserted between the sulfur cathode and the separator to capture and trap these soluble intermediates has been found effective in diminishing this effect. Previously, most reported interlayer membranes were synthesized in a complex and expensive process, and might not be suitable for practical cheap batteries. Herein, a facile method is reported to pyrolyze the commonly used cellulose filter paper into highly flexible and conductive carbon fiber paper. When used as an interlayer, such a carbon paper can improve the cell capacity by several folds through trapping the soluble polysulfides. The enhanced electronic conductivity of the cathode, due to the interlayer, also significantly improves the cell rate performance. In addition, it was demonstrated that such an interlayer can also effectively mitigate the self-discharge problem of the Li-S batteries. This study indicates that the cost-effective pyrolyzed cellulose paper has potential as interlayer for practical Li-S batteries.

Comparative life cycle assessments: The case of paper and digital media

Energy Technology Data Exchange (ETDEWEB)

Bull, Justin G., E-mail: jgbull@gmail.com; Kozak, Robert A., E-mail: rob.kozak@ubc.ca

2014-02-15

The consumption of the written word is changing, as media transitions from paper products to digital alternatives. We reviewed the life cycle assessment (LCA) research literature that compared the environmental footprint of digital and paper media. To validate the role of context in influencing LCA results, we assessed LCAs that did not compare paper and print, but focused on a product or component that is part of the Information and Communication Technology (ICT) sector. Using a framework that identifies problems in LCA conduct, we assessed whether the comparative LCAs were accurate expressions of the environmental footprints of paper and print. We hypothesized that the differences between the product systems that produce paper and digital media weaken LCA's ability to compare environmental footprints. We also hypothesized that the characteristics of ICT as an industrial sector weaken LCA as an environmental assessment methodology. We found that existing comparative LCAs offered problematic comparisons of paper and digital media for two reasons — the stark material differences between ICT products and paper products, and the unique characteristics of the ICT sector. We suggested that the context of the ICT sector, best captured by the concept of “Moore's Law”, will continuously impede the ability of the LCA methodology to measure ICT products. -- Highlights: • We review the LCA research that compares paper and digital media. • We contrast the comparative LCAs with LCAs that examine only digital products. • Stark differences between paper and digital media weakens LCA findings. • Digital products in general challenge the LCA method's reliability. • Continuous innovation and global nature of digital products impedes LCA methodology.

Humidity Sensors Printed on Recycled Paper and Cardboard

Directory of Open Access Journals (Sweden)

Matija Mraović

2014-07-01

Full Text Available Research, design, fabrication and results of various screen printed capacitive humidity sensors is presented in this paper. Two types of capacitive humidity sensors have been designed and fabricated via screen printing on recycled paper and cardboard, obtained from the regional paper and cardboard industry. As printing ink, commercially available silver nanoparticle-based conductive ink was used. A considerable amount of work has been devoted to the humidity measurement methods using paper as a dielectric material. Performances of different structures have been tested in a humidity chamber. Relative humidity in the chamber was varied in the range of 35%–80% relative humidity (RH at a constant temperature of 23 °C. Parameters of interest were capacitance and conductance of each sensor material, as well as long term behaviour. Process reversibility has also been considered. The results obtained show a mainly logarithmic response of the paper sensors, with the only exception being cardboard-based sensors. Recycled paper-based sensors exhibit a change in value of three orders of magnitude, whereas cardboard-based sensors have a change in value of few 10s over the entire scope of relative humidity range (RH 35%–90%. Two different types of capacitor sensors have been investigated: lateral (comb type sensors and modified, perforated flat plate type sensors. The objective of the present work was to identify the most important factors affecting the material performances with humidity, and to contribute to the development of a sensor system supported with a Radio Frequency Identification (RFID chip directly on the material, for use in smart packaging applications. Therefore, the authors built a passive and a battery-supported wireless module based on SL900A smart sensory tag’s IC to achieve UHF-RFID functionality with data logging capability.

Large-scale genome sequencing has identified millions of protein-coding genes whose function is unknown. Many of these proteins are similar to characterized proteins from other organisms, but much of this information is missing from annotation databases and is hidden in the scientific literature. To make this information accessible, PaperBLAST uses EuropePMC to search the full text of scientific articles for references to genes. PaperBLAST also takes advantage of curated resources (Swiss-Prot, GeneRIF, and EcoCyc) that link protein sequences to scientific articles. PaperBLAST's database includes over 700,000 scientific articles that mention over 400,000 different proteins. Given a protein of interest, PaperBLAST quickly finds similar proteins that are discussed in the literature and presents snippets of text from relevant articles or from the curators. PaperBLAST is available at http://papers.genomics.lbl.gov/. IMPORTANCE With the recent explosion of genome sequencing data, there are now millions of uncharacterized proteins. If a scientist becomes interested in one of these proteins, it can be very difficult to find information as to its likely function. Often a protein whose sequence is similar, and which is likely to have a similar function, has been studied already, but this information is not available in any database. To help find articles about similar proteins, PaperBLAST searches the full text of scientific articles for protein identifiers or gene identifiers, and it links these articles to protein sequences. Then, given a protein of interest, it can quickly find similar proteins in its database by using standard software (BLAST), and it can show snippets of text from relevant papers. We hope that PaperBLAST will make it easier for biologists to predict proteins' functions.

Full Text Available Paper is a fascinating material that we encounter every day in different variants: tissues, paper towels, packaging material, wall paper or even fillers of doors. Despite radical changes in production technology, the material, which has been known to mankind for almost two thousand years, still has a natural composition, being made up of fibres of plant origin (particularly wood fibres. Thanks to its unique properties, relatively high compression strength and bending stiffness, low production costs and ease of recycling, paper is becoming more and more popular in many types of industry. Mass-produced paper products such as special paper, paperboard, corrugated cardboard, honeycomb panels, tubes and L- and U-shapes are suitable for use as a building material in the broad sense of these words – i.e., in design and architecture. Objects for everyday use, furniture, interior design elements and partitions are just a few examples of things in which paper can be employed. Temporary events such as festivals, exhibitions or sporting events like the Olympics require structures that only need to last for a limited period of time. When they are demolished after a few days or months, their leftovers can have a significant impact on the local environment. In the context of growing awareness of environmental threats and the efforts undertaken by local and international organisations and governments to counter these threats, the use of natural materials that can be recycled after their lifespan is becoming increasingly widespread. Paper and its derivatives fascinate designers and architects, who are always looking for new challenges and trying to meet the market’s demands for innovative and proecological solutions. Being a low-cost and readily available material, paper is suited to the production of emergency shelters for victims of natural and man-made disasters, as well as homeless persons. In order to gain a better understanding of paper’s potential

Full Text Available AIM: To identify the 100 most cited papers in cataract surgery, we performed a comprehensive bibliometric analysis basing on the literature search on the Thomson Reuters Web of Knowledge. METHODS: The number of citations, including the total citations, latest 5y citations and average citation number per year (ACY, authorship, year of publication, major topics, journal of publication, country and institution of origin of each paper were recorded and then analyzed. Pearson’s correlation analysis was conducted to evaluate the correlation between the published year and the number of citations. The correlation between journal’s impact factor (IF and number of citations was assessed as well. RESULTS: The most cited paper was the classic paper done by the European Society of Cataract & Refractive Surgeons (ESCRS group. This paper focused on the topic of endophthalmitis. Not only the most cited papers originated from the USA, but also some American institutions like Johns Hopkins University, Harvard Medical School, etc. had the most citations. Pearson’s correlation analysis indicated that the latest 5y citations and ACY were significantly related with the published year (5y citations: r=0.615, P<0.001; ACY: r=0.657, P<0.001, whereas no association between the total number of citations and published year was found (r=0.045. Moreover, the IFs of journals were found to have no significant effect on the number of total citations. CONCLUSION: To our knowledge, this is the first study on the most influential papers in cataract surgery after a comprehensive research of relevant literatures. The present work may provide us concise information concerning the development history of cataract surgery over the past 66y.

Paper drying is the most energy-intensive and temperature-critical aspect of papermaking. It is estimated that about 67% of the total energy required in papermaking is used to dry paper. The conventional drying method uses a series of steam-heated metal cylinders that are required to meet ASME codes for pressure vessels, which limits the steam pressure to about 160 psig. Consequently, the shell temperature and the drying capacity are also limited. Gas Technology Institute together with Boise Paper Solutions, Groupe Laparrier and Verreault (GL&V) USA Inc., Flynn Burner Corporation and with funding support from the U.S. Department of Energy, U.S. natural gas industry, and Gas Research Institute is developing a high efficiency gas-fired paper dryer based on a combination of a ribbon burner and advanced heat transfer enhancement technique. The Gas-Fired Paper Dryer (GFPD) is a high-efficiency alternative to conventional steam-heated drying drums that typically operate at surface temperatures in the 300ºF range. The new approach was evaluated in laboratory and pilot-scale testing at the Western Michigan University Paper Pilot Plant. Drum surface temperatures of more than 400ºF were reached with linerboard (basis weight 126 lb/3000 ft2) production and resulted in a 4-5 times increase in drying rate over a conventional steam-heated drying drum. Successful GFPD development and commercialization will provide large energy savings to the paper industry and increase paper production rates from dryer-limited (space- or steam-limited) paper machines by an estimated 10 to 20%, resulting in significant capital costs savings for both retrofits and new capacity.

Paper currency and coins may be a public health risk when associated with the simultaneous handling of food and could lead to the spread of nosocomial infections. Banknotes recovered from hospitals may be highly contaminated by Staphylococcus aureus. Salmonella species, Escherichia coli and S. aureus are commonly isolated from banknotes from food outlets. Laboratory simulations revealed that methicillin-resistant S. aureus can easily survive on coins, whereas E. coli, Salmonella species and viruses, including human influenza virus, Norovirus, Rhinovirus, hepatitis A virus, and Rotavirus, can be transmitted through hand contact. Large-scale, 16S rRNA, metagenomic studies and culturomics have the capacity to dramatically expand the known diversity of bacteria and viruses on money and fomites. This review summarizes the latest research on the potential of paper currency and coins to serve as sources of pathogenic agents.

Nanthasurasak, Pavisara; Cabot, Joan Marc; See, Hong Heng; Guijt, Rosanne M; Breadmore, Michael C

2017-09-08

Point-of-collection (POC) devices aim for a fast, on-site detection for medical and environmental purposes. In this area, microfluidic Paper-based Analytical Devices (μPADs) have recently gained popularity because these are potentially cheap and environmentally friendly to produce, and easy to use. From an analytical perspective, paper is well known for its use as a substrate for chromatography, but less known for its use in electrophoretic separations. With the recent interest in μPADs, most applications are based on rather simple assays with relatively few applications incorporating an analytical separation. The focus of this review is on paper-based electrophoresis, originating with the key developments in the 1940s and 1950s as well as the recent developments of electrophoretic μPADs, and concluding with a critical discussion of the opportunities and challenges for electrophoretic μPADS in the future.

New approach to recycling and waste-to-energy in paper production, Urban Mill

Energy Technology Data Exchange (ETDEWEB)

Ristola, P. [Metso Corporation (Finland)

2002-10-01

Greenfield paper mills are commonly perceived as massive investments with a high level of associated impact on the local environment. Parallel to this, increasingly strict targets are being set by modem legislation for reducing waste disposal at landfills. One long-term solution to this dilemma lies in extended materials recycling, combined with effective utilisation of waste as energy. Metso Paper's Urban Mill is a unique pilot concept that promises to become an important part of such a solution. The novelty of Metso Paper's new eco-efficient Urban Mill concept lies in its combination of a small paper mill with using solid waste to generate energy. The roots of the concept go back to the early 1990s, when several mini-mills were built to produce raw materials for corrugated containers in North America. The competitiveness of mini-mills like this is based on several benefits: lowcost, high-quality waste paper raw material, utilisation of adjacent facilities for utilities, and modern machines with lean manning and low inbound and outbound logistics costs.

A study on oxygen-plasma treatment of ink-jet paper is presented. Paper was exposed to a weakly ionized, highly dissociated oxygen plasma with an electron temperature of 5 eV, a positive-ion density of 8 x 10{sup 15} m{sup -3} and a density of neutral oxygen atoms of 5 x 10{sup 21} m{sup -3}. Optical emission spectroscopy (OES) was applied as a method for detection of the reaction products during the plasma treatment of the paper. OES spectra between 250 and 1000 nm were measured continuously during the plasma treatment. The wettability of the samples before and after the plasma treatment was determined by measuring the contact angle of a water drop. The appearance of the surface-functional groups was determined by using high-resolution x-ray photoelectron spectroscopy (XPS), while changes in the surface morphology were monitored with scanning electron microscopy (SEM). Already after 1 s of the plasma treatment the surface, which was originally hydrophobic, changed to hydrophilic, as indicated by a high absorption rate of a water drop into the paper. The OES showed a rapid increase of the CO and OH bands for the first few seconds of the plasma treatment, followed by a slow decrease during the next 40 s. The intensity of the O atom line showed reversed behaviour. The XPS analyses showed a gradual increase of oxygen-rich functional groups on the surface, while SEM analyses did not show significant modification of the morphology during the first 10 s of the plasma treatment. The results were explained by degradation of the alkyl ketene dimer sizing agent during the first few seconds of the oxygen-plasma treatment.

Our understanding of the ecology and management of North American forests is rapidly evolving as a result of novel approaches to their study, many of which are the results of emerging technologies. The biennial North American Forest Ecology Workshop series attempts to capture these approaches and highlight the ways in which they expand our understanding of forest systems. The ten papers appearing in this issue were drawn from the 7th and most recent workshop, held in June 2009, in which there were over 150 presentations. The first paper in this special issue attempts to provide an overview of emerging themes in the ecology and management of North American Forests based on all presentations and follow-up discussions at the workshop and concludes with future research needs. The second paper describes the carbon flux of down woody materials in forests of the North central U.S. using recent data from the USDA Forest Services Forest Inventory and Analysis (FIA) Program and exemplifies the utility of a network of permanent plots for monitoring change over large spatial scales and long time periods. The study described in the third paper is a nice sequel to the second in that it uses FIA data to demonstrate changes in the population levels of an understory tree in eastern North America threatened by an introduced pathogen, among other causes. The authors point out that such data can be used to validate the findings of multiple small-scale studies and to generate hypotheses for testing at smaller scales, thereby reinforcing a workshop-wide call for the study of forest ecosystems at multiple scales.

Sarfraz, J.; Ihalainen, P.; Määttänen, A.; Peltonen, J.; Lindén, M.

2013-01-01

The fabrication of a hydrogen sulfide (H 2 S) sensor based on polyaniline (PANI)-metal salt (CuCl 2 ) composite is demonstrated. The sensing film was produced by screen printing and spray coating of the sensing material on interdigitated silver electrodes inkjet-printed on a paper substrate. The H 2 S sensing functionality with respect to pH and metal salt concentration was optimized. In addition, the long term stability and humidity effects on the sensor performance were investigated. The printed chemiresistors showed more than five orders of magnitude change in resistance within 20 min of exposure of 15 ppm H 2 S at room temperature. The relatively fast kinetics and large response of the sensor can be explained by the formation of Cu 2 S and subsequent protonation of PANI. In addition, the relatively large roughness and porosity of the paper substrate offers an increased surface sensing area. - Highlights: • pH, salt concentration, film thickness, cross sensitivity • Printed sensor on paper substrate • Commercial polyaniline against special morphologies

Paper capillary is introduced to enable effective sampling on microfluidic paper analytical devices. By coupling mac-roscale capillary force of paper capillary and microscale capillary forces of native paper, fluid transport can be flexibly tailored with proper design. Subsequently, a hybrid-fluid-mode paper capillary device was proposed, which enables fast and reliable sampling in an arrayed form, with less surface adsorption and bias for different components. The resulting device thus well supports high throughput, quantitative, and repeatable assays all by hands operation. With all these merits, multiplex analysis of ions, proteins, and microbe have all been realized on this platform, which has paved the way to level-up analysis on μPADs.

Laminated and infused Parafilm® - paper for paper-based analytical devices.

2018-02-01

Numerous fabrication methods have been reported for microfluidic paper-based analytical devices (μPADs) using barrier materials ranging from photoresist to wax. While these methods have been used with wide success, consistently producing small, high-resolution features using materials and methods that are compatible with solvents and surfactants remains a challenge. Two new methods are presented here for generating μPADs with well-defined, high-resolution structures compatible with solvents and surfactant-containing solutions by partially or fully fusing paper with Parafilm® followed by cutting with a CO 2 laser cutter. Partial fusion leads to laminated paper ( l -paper) while the complete fusion results in infused paper ( i -paper). Patterned structures in l -paper were fabricated by selective removal of the paper but not the underlying Parafilm® using a benchtop CO 2 laser. Under optimized conditions, a gap as small as 137 ± 22 μm could be generated. Using this approach, a miniaturized paper 384-zone plate, consisting of circular detection elements with a diameter of 1.86 mm, was fabricated in 64 × 43 mm 2 area. Furthermore, these ablation-patterned substrates were confirmed to be compatible with surfactant solutions and common organic solvents (methanol, acetonitrile and dimethylformamide), which has been achieved by very few μPAD patterning techniques. Patterns in i -paper were created by completely cutting out zones of the i -paper and then fixing pre-cut paper into these openings similar to the strategy of fitting a jigsaw piece into a puzzle. Upon heating, unmodified paper was readily sealed into these openings due to partial reflow of the paraffin into the paper. This unique and simple bonding method was illustrated by two types of 3D μPADs, a push-on valve and a time-gated flow distributor, without adding adhesive layers. The free-standing jigsaw-patterned sheets showed good structural stability and solution compatibility, which provided a facile

Issue Paper on Physiological and Behavioral Changes in ...

Science.gov (United States)

This issue paper provides a summary of information from the published literature related to behavioral and physiological changes during pregnancy and lactation that may affect women’s exposure or susceptibility to environmental contaminants, provides potentially useful exposure factor data for this population of women, and highlights data gaps. Background Exposures to environmental contaminants can pose a risk to pregnant women’s health, the developing fetus, children, and adults later in their lives. Assessing risks to this potentially susceptible population requires an understanding of the physiological and behavioral changes that occur during pregnancy and lactation. Many physiological and anatomical changes occur in a woman’s organ systems during the course of pregnancy and lactation. For example, blood volume and cardiac output increase during pregnancy, and other metabolic functions are altered to provide for the demands of the fetus. Nutritional demands are greater during pregnancy and lactation. There also are changes in behavior during both pregnancy and lactation. For example, water consumption during pregnancy and lactation increases. These behavioral and physiological changes can lead to different environmental exposures than these women might otherwise experience in the absence of pregnancy or lactation. The purpose of the issue paper is to provide a summary of data available on physiological and behavioral changes in pregnant a

Tao, Xinglei; Jia, Hanyu; He, Yonglin; Liao, Shenglong; Wang, Yapei

2017-03-24

With the use of an ionic liquid as the ultrathermosensitive fluid, a paper thermometer is successfully developed with intrinsic ability of ultrafast response and high stability upon temperature change. The fluidic nature allows the ionic liquid to be easily deposited on paper by pen writing or inkjet printing, affording great promise for large-scale fabrication of low-cost paper sensors. Owing to the advantages of nonvolatilization, excellent continuity and deformability, the thermosensitive ink trapped within the cellulose fibers of paper matrix has no leakage or evaporation at open states, ensuring the excellent stability and repeatability of thermal sensing against arbitrary bending and folding operation. By shortening the heat exchange distance between ionic liquid and samples, it takes only 8 s for the thermometer to reach an electrical equilibrium at a given temperature. Moreover, the paper thermometer can be applied to remotely monitor temperature change with the combination of a wireless communication technology.

The pulp and paper industry ranks fourth in terms of energy consumption among industries worldwide. Globally, the pulp and paper industry accounted for approximately 5 percent of total world industrial final energy consumption in 2007, and contributed 2 percent of direct carbon dioxide (CO2) emissions from industry. Worldwide pulp and paper demand and production are projected to increase significantly by 2050, leading to an increase in this industry’s absolute energy use and greenhouse gas (GHG) emissions. Development of new energy-efficiency and GHG mitigation technologies and their deployment in the market will be crucial for the pulp and paper industry’s mid- and long-term climate change mitigation strategies. This report describes the industry’s processes and compiles available information on the energy savings, environmental and other benefits, costs, commercialization status, and references for 36 emerging technologies to reduce the industry’s energy use and GHG emissions. Although studies from around the world identify a variety of sector-specific and cross-cutting energy-efficiency technologies that have already been commercialized for the pulp and paper industry, information is scarce and/or scattered regarding emerging or advanced energy-efficiency and low-carbon technologies that are not yet commercialized. The purpose of this report is to provide engineers, researchers, investors, paper companies, policy makers, and other interested parties with easy access to a well-structured resource of information on these technologies.

Lambert’s Influence on Kant’s Theoretical Philosophy

Adriano Perin

2016-06-01

Full Text Available This paper aims at presenting a reconstruction of the main theses of Lambert’s thought and their role in the establishment of Kant’s theoretical philosophy. In order to do so, the paper is divided into three sections. Initially, a consideration of Lambert’s attempt to assure illusion (Schein within the domain of phenomenology (Körperwelt and to institute the domain of metaphysical truth (Intellectualwelt is carried out. Secondly, Kant’s first step away from Lambert’s proposal, which is presented in the Inaugural Dissertation’s thesis that the sensible and intellectual domains of knowledge are grounded upon two distinct and intransmutable faculties, is taken into account. Finally, Kant’s definitive step away from Lambert’s proposal, i.e., the justification of appearances in the Duisburg Nachlaβ in an objective and non-illusory domain, due to the determination of the faculty of understanding, is pointed out.

2013-12-01

Full Text Available Aim of study: The purpose of this study is to analyze how paper recycling activities in Europe can be extended through different improvements along the paper value chain. The importance of this study lies in the identification of the present barriers in paper recycling and how they can be overcome.Area of study: Europe.Material and Methods: All the main stages along the paper value chain have been analyzed for possible improvements: collection of recovered paper (availability and quality, sorting of recovered paper, paper production, and printing and converting activities.Main results: To increase paper recycling in Europe the following improvements are necessary. First, it is mandatory to increase the availability of recovered paper through more efficient collection systems (avoiding the use of commingled collection systems and limiting the competition with energy purposes and the exports. Second, it is necessary to extend sorting activities, which can be achieved by reducing sorting costs by the use of automatized sorting systems. Third, there is a need to increase the recyclability of paper products by the commitment of printing and converting industries to use recycling-friendly printing inks and adhesives. Finally, environmental awareness of the citizens is still an important driver for increasing recycling activities, affecting not only recovery but to all the stages along the paper recycling chain.Research highlights: Although the recycling rate in Europe is already very high (68.9%, there is still room to further extend paper recycling activities through different improvements along the paper value chain.Keywords: paper recycling; sustainability; paper value chain; recovered paper; environmental awareness.

[Truth curves on soot blackened paper--apparatus-supported lie detection in Graz in the 1920s].

Science.gov (United States)

Bachhiesl, Christian

2014-01-01

In the 1920s, experiments with apparatus-supported lie detection and registration of expression were conducted at the Criminological Institute of the University of Graz in order to establish a sound methodological basis for testimony research. For this purpose, the criminologist Ernst Seelig used a method of lie detection developed by the psychologist Vittorio Benussi, which focuses on the analysis of breathing. Benussi had stated that the expiration after telling a lie was faster than after telling the truth, but Seelig could not verify this rule in forensic practice. Consequently, this method of lie detection was of no practical use for criminology. Seelig also carried out experiments with the method of registration of expression developed by the psychiatrist Otto Lowenstein. He registered the examinee's thoracic and abdominal breathing and the movements of the extremities with the help of a kymograph. By interpretation of the curves recorded on soot blackened paper, conclusions concerning the mental elements of an offence as well as the existence of certain dispositions and of amnesia should have been made possible. Seelig was convinced of the efficiency of this method. These experiments can be regarded as early attempts at finding not only simple facts but also answers to quasi-metaphysical questions concerning the "true nature" of man with the help of methods based on natural science and modern technology. Thus they are precursors of present-day neuroscience and neuro-imaging.

We demonstrate the fabrication of a graphene-based field effect transistor (GFET) incorporated in a two-dimensional paper network format (2DPNs). Paper serves as both a gate dielectric and an easy-to-fabricate vessel for holding the solution with the target molecules in question. The choice of paper enables a simpler alternative approach to the construction of a GFET device. The fabricated device is shown to behave similarly to a solution-gated GFET device with electron and hole mobilities of ∼1256 cm 2  V −1  s −1 and ∼2298 cm 2  V −1  s −1 respectively and a Dirac point around ∼1 V. When using solutions of ssDNA and glucose it was found that the added molecules induce negative electrolytic gating effects shifting the conductance minimum to the right, concurrent with increasing carrier concentrations which results to an observed increase in current response correlated to the concentration of the solution used. - Highlights: • A graphene-based field effect transistor sensor was fabricated for two-dimensional paper network formats. • The constructed GFET on 2DPN was shown to behave similarly to solution-gated GFETs. • Electrolyte gating effects have more prominent effect over adsorption effects on the behavior of the device. • The GFET incorporated on 2DPN was shown to yield linear response to presence of glucose and ssDNA soaked inside the paper.

U.S. Radioecology Research Programs of the Atomic Energy Commission in the 1950s

Energy Technology Data Exchange (ETDEWEB)

Reichle, D.E.

2004-01-12

This report contains two companion papers about radiological and environmental research that developed out of efforts of the Atomic Energy Commission in the late 1940s and the 1950s. Both papers were written for the Joint U.S.-Russian International Symposium entitled ''History of Atomic Energy Projects in the 1950s--Sociopolitical, Environmental, and Engineering Lessons Learned,'' which was hosted by the International Institute for Applied Systems Analysis in Laxemberg, Austria, in October 1999. Because the proceedings of this symposium were not published, these valuable historic reviews and their references are being documented as a single ORNL report. The first paper, ''U.S. Radioecology Research Programs Initiated in the 1950s,'' written by David Reichle and Stanley Auerbach, deals with the formation of the early radioecological research programs at the U.S. Atomic Energy Commission's nuclear production facilities at the Clinton Engineering Works in Oak Ridge, Tennessee; at the Hanford Plant in Richland, Washington; and at the Savannah River Plant in Georgia. These early radioecology programs were outgrowths of the environmental monitoring programs at each site and eventually developed into the world renowned National Laboratory environmental program sponsored by the Office of Biological and Environmental Research of the U.S. Department of Energy. The original version of the first paper was presented by David Reichle at the symposium. The second paper, ''U.S. Atomic Energy Commission's Environmental Research Programs Established in the 1950s,'' summarizes all the environmental research programs supported by the U.S. Atomic Energy Commission in the 1950s and discusses their present-day legacies. This paper is a modified, expanded version of a paper that was published in September 1997 in a volume commemorating the 50th anniversary symposium of the U.S. Department of Energy's Office of

This paper describes 96- and 384-microzone plates fabricated in paper as alternatives to conventional multiwell plates fabricated in molded polymers. Paper-based plates are functionally related to plastic well plates, but they offer new capabilities. For example, paper-microzone plates are thin (approximately 180 microm), require small volumes of sample (5 microL per zone), and can be manufactured from inexpensive materials ($0.05 per plate). The paper-based plates are fabricated by patterning sheets of paper, using photolithography, into hydrophilic zones surrounded by hydrophobic polymeric barriers. This photolithography used an inexpensive formulation photoresist that allows rapid (approximately 15 min) prototyping of paper-based plates. These plates are compatible with conventional microplate readers for quantitative absorbance and fluorescence measurements. The limit of detection per zone loaded for fluorescence was 125 fmol for fluorescein isothiocyanate-labeled bovine serum albumin, and this level corresponds to 0.02 the quantity of analyte per well used to achieve comparable signal-to-noise in a 96-well plastic plate (using a solution of 25 nM labeled protein). The limits of detection for absorbance on paper was approximately 50 pmol per zone for both Coomassie Brilliant Blue and Amaranth dyes; these values were 0.4 that required for the plastic plate. Demonstration of quantitative colorimetric correlations using a scanner or camera to image the zones and to measure the intensity of color, makes it possible to conduct assays without a microplate reader.

Condition Assessment of Paper Insulation in Oil-Immersed Power Transformers Based on the Iterative Inversion of Resistivity

2017-04-01

Full Text Available The resistivity of oil impregnated paper will decrease during its aging process. This paper takes paper resistivity as an assessment index to evaluate the insulation condition of oil impregnated paper in power transformer. The feasibility of this method are discussed in two aspects: reliability and sensitivity. Iterative inversion of paper resistivity was combined with finite element simulation. Both the bisection method and Newton’s method were used as iterative methods. After the analysis and comparison, Newton’s method was selected as the first option of paper resistivity iteration for its faster convergence. In order to consider the spatial distribution characteristic of paper aging and enhance the calculation accuracy, the resistivity calculation is expanded to a multivariate iteration based on Newton’s method, in order to consider the spatial distribution characteristic of paper aging and improve the calculation accuracy. This paper presents an exploratory research on condition assessment of oil impregnated paper insulation, and provides some reference to the security and economy operation of power transformers.

Full Text Available This short film, “From a Sheet of Paper to the Sky”, grew out of research that I conducted for an essay of the same title, written for the catalogue accompanying the Paul Nash exhibition at Tate Britain (October 2016 to March 2017. In that essay, I argued against the traditional art historical tendency to review an artist’s work in different media separately, and instead proposed that a consideration of Paul Nash’s painting alongside his three-dimensional and textile designs, his printmaking, and photography, resulted in a fuller understanding of both the conceptual underpinnings and the recurring visual motifs in Nash’s work.

2017-07-01

The anterior cruciate ligament (ACL) is one of the most common injured knee ligaments and at the same time, one of the most frequent injuries seen in the sport orthopaedic practice. Due to the clinical relevance of ACL injuries, numerous papers focussing on this topic including biomechanical-, basic science-, clinical- or animal studies, were published. The purpose of this study was to determine the most frequently cited scientific articles which address this subject, establish a ranking of the 50 highest cited papers and analyse them according to their characteristics. The 50 highest cited articles related to Anterior Cruciate Ligament Injury were searched in Thomson ISI Web of Science® by the use of defined search terms. All types of scientific papers with reference to our topic were ranked according to the absolute number of citations and analyzed for the following characteristics: journal title, year of publication, number of citations, citation density, geographic origin, article type and level of evidence. The 50 highest cited articles had up to 1624 citations. The top ten papers on this topic were cited 600 times at least. Most papers were published in the American Journal of Sports Medicine. The publication years spanned from 1941 to 2007, with the 1990s and 2000s accounting for half of the articles (n = 25). Seven countries contributed to the top 50 list, with the USA having by far the most contribution (n = 40). The majority of articles could be attributed to the category "Clinical Science & Outcome". Most of them represent a high level of evidence. Scientific articles in the field of ACL injury are highly cited. The majority of these articles are clinical studies that have a high level of evidence. Although most of the articles were published between 1990 and 2007, the highest cited articles in absolute and relative numbers were published in the early 1980s. These articles contain well established scoring- or classification systems. The

Cooperative Monitoring Center Occasional Paper/9: De-Alerting Strategic Ballistic Missiles

Energy Technology Data Exchange (ETDEWEB)

Connell, Leonard W.; Edenburn, Michael W.; Fraley, Stanley K.; Trost, Lawrence C.

1999-03-01

This paper presents a framework for evaluating the technical merits of strategic ballistic missile de-alerting measures, and it uses the framework to evaluate a variety of possible measures for silo-based, land-mobile, and submarine-based missiles. De-alerting measures are defined for the purpose of this paper as reversible actions taken to increase the time or effort required to launch a strategic ballistic missile. The paper does not assess the desirability of pursuing a de-alerting program. Such an assessment is highly context dependent. The paper postulates that if de-alerting is desirable and is used as an arms control mechanism, de-alerting measures should satisfy specific cirteria relating to force security, practicality, effectiveness, significant delay, and verifiability. Silo-launched missiles lend themselves most readily to de-alerting verification, because communications necessary for monitoring do not increase the vulnerabilty of the weapons by a significant amount. Land-mobile missile de-alerting measures would be more challenging to verify, because monitoring measures that disclose the launcher's location would potentially increase their vulnerability. Submarine-launched missile de-alerting measures would be extremely challlenging if not impossible to monitor without increasing the submarine's vulnerability.

U.S. reference paper on national decisions on breeder development and deployment

International Nuclear Information System (INIS)

1978-10-01

Factors involved in making national decisions on the deployment of breeder reactor systems are identified in terms of a nation's potential for electrification, capital resources, the available industrial and manpower infrastructure and importance attached to energy independence and the degree to which a breeder program can help realize this objective in the time scale of interest. The specific factors analysed are: the high capital cost of the breeder and the one-time transition costs to bring the breeder to maturity the high breeder research, development and demonstration costs, the impact of discount rate, and the fuel cycle costs, e.g. indigeneous facilities or purchase of services. A principal conclusion of this paper is that nations may find it more economical to continue to deploy LWRs for a number of years rather than to consider the breeder option because of the initial high breeder capital cost and high breeder R and D costs

2016-06-01

Editor's note: Albert Mason discovered an unpublished paper by Donald Meltzer dating from around 1968 and has made the text available to the IJP. He writes "my best guess is that Meltzer gave me the paper to read/approve about the time I was preparing to move to Los Angeles (1968-69) and that I hastily packed it away with other papers. It got buried, and only came to light recently, kind of like a lost score that turns up in someone's attic!" The patient Meltzer discusses in his paper is a patient who Dr Mason treated for approximately 11 years, and about whom Dr Mason consulted with Dr Meltzer early in the treatment. Dr Mason has also provided the original report he wrote about the patient in the 1960s. Following an introduction by Dr Abbot Bronstein, we have published extracts from Dr Mason's report, including the following: details about the case, the two dreams which Dr Mason believes were 'turning point dreams', and a third dream called the 'hula hula dream', as well as the clinical material leading up to it.

Do Adolescents Prefer Electronic Books to Paper Books?

Directory of Open Access Journals (Sweden)

Margaret K. Merga

2015-11-01

Full Text Available While electronic books offer a range of benefits and may be supposed to be more appealing to young people than paper books, this assumption is often treated as fact by educational researchers. Understanding adolescents’ true current preferences is essential, as incorrect assumptions can lead to decisions which restrict adolescent access to their preferred book mode. The belief that adolescents prefer electronic books to paper books has already led to some school libraries being expunged of paper books. As adolescents show a higher level of aliteracy than younger children, and regular reading offers a broad range of benefits for young people, it is imperative that school’s decisions around providing access to books are responsive to adolescent students’ genuine preferences. This paper analyses the current and relevant academic research around adolescent preferences for book modes, finding that, at present, the contention that adolescents prefer electronic books is not supported by the available research. In addition, there are a number of issues identified that make analyzing the findings in this area problematic. Future studies in this area are needed before an adolescent preference for electronic books can be unequivocally substantiated.

Similarity between Newtonian gravitational force and Coulomb’s force leads one to define gravitational electric and magnetic fields or gravito-electromagnetic fields. Also, one may define a gravitational Bohr’s theory in analogy with the electromagnetic Bohr’s theory for which the latter is quite successful in explaining some properties of hydrogen atom. Unlike to the Coulomb’s force, the Newton‘s force is believed to be an approximated theory of gravity as it is unable to explain the Mercury’s orbit. This paper discusses the gravitational Bohr’s theory by taking into account the Newton’s potential and Weber’s potential; the later is a modified Newton’s gravitational potential that conforms, to some degrees, to the anomaly of the Mercury’s orbit.

Biofilms cause runnability problems in paper machines and are therefore controlled with biocides. Peracetic acid is usually effective in preventing bulky biofilms. This study investigated the microbiological status of a paper machine where low concentrations (≤ 15 ppm active ingredient) of peracetic acid had been used for several years. The paper machine contained a low amount of biofilms. Biofilm-forming bacteria from this environment were isolated and characterized by 16S rRNA gene sequencing, whole-cell fatty acid analysis, biochemical tests, and DNA fingerprinting. Seventy-five percent of the isolates were identified as members of the subclades Sphingomonas trueperi and S. aquatilis, and the others as species of the genera Burkholderia (B. cepacia complex), Methylobacterium, and Rhizobium. Although the isolation media were suitable for the common paper machine biofoulers Deinococcus, Meiothermus, and Pseudoxanthomonas, none of these were found, indicating that peracetic acid had prevented their growth. Spontaneous, irreversible loss of the ability to form biofilm was observed during subculturing of certain isolates of the subclade S. trueperi. The Sphingomonas isolates formed monoculture biofilms that tolerated peracetic acid at concentrations (10 ppm active ingredient) used for antifouling in paper machines. High pH and low conductivity of the process waters favored the peracetic acid tolerance of Sphingomonas sp. biofilms. This appears to be the first report on sphingomonads as biofilm formers in warm water using industries.

The physics of paper

Paper is a material known to everybody. It has a network structure consisting of wood fibres that can be mimicked by cooking a portion of spaghetti and pouring it on a plate, to form a planar assembly of fibres that lie roughly horizontal. Real paper also contains other constituents added for technical purposes. This review has two main lines of thought. First, in the introductory part, we consider the physics that one encounters when 'using' paper, an everyday material that exhibits the presence of disorder. Questions arise, for instance, as to why some papers are opaque and others translucent, some are sturdy and others sloppy, some readily absorb drops of liquid while others resist the penetration of water. The mechanical and rheological properties of paper and paperboard are also interesting. They are inherently dependent on moisture content. In humid conditions paper is ductile and soft, in dry conditions brittle and hard. In the second part we explain in more detail research problems concerned with paper. We start with paper structure. Paper is made by dewatering a suspension of fibres starting from very low content of solids. The processes of aggregation, sedimentation and clustering are familiar from statistical mechanics. Statistical growth models or packing models can simulate paper formation well and teach a lot about its structure. The second research area that we consider is the elastic and viscoelastic properties and fracture of paper and paperboard. This has traditionally been the strongest area of paper physics. There are many similarities to, but also important differences from, composite materials. Paper has proved to be convenient test material for new theories in statistical fracture mechanics. Polymer physics and memory effects are encountered when studying creep and stress relaxation in paper. Water is a 'softener' of paper. In humid conditions, the creep rate of paper is much higher than in dry conditions. The third among our topics is the

Besides the structural properties supporting microfluidics, other advantageous features of paper materials, including their versatility, disposability and low cost, show off the great potential for the development of advanced and eco-friendly analytical tools. Consequently, paper was quickly employed in the field of electrochemical sensors, being an ideal material for producing custom, tailored and miniaturized devices. Stencil-, inkjet-, or screen-printing are the preferential techniques for electrode manufacturing. Not surprisingly, we witnessed a rapid increase in the number of publications on paper based screen-printed sensors at the turn of the past decade. Among the sensing strategies, various biosensors, coupling electrochemical detectors with biomolecules, have been proposed. This work provides a critical review and a discussion on the future progress of paper technology in the context of miniaturized printed electrochemical biosensors.

Paper on Designing Costless THz Paper Optics

Directory of Open Access Journals (Sweden)

A. Siemion

2016-01-01

Full Text Available Designing diffractive optical elements is crucial for efficient development of THz techniques. Here, we consider paper structures and we analyze their advantages and disadvantages in fast prototyping. The discussion about using material parameters like refractive index and absorption coefficient in designing diffractive optical elements is shown. We analyze the influence of phase step mismatch, of attenuation of real structure, and of nonuniform illumination on the efficiency of the structure. All these features result in worsening of the diffraction efficiency but they do not seem to have such significant influence as shadow effect introduced by fast varying zones. Diffractive elements can be designed with very good accordance with experimental results which makes them ideal for possible applications. Paper optics scan be used more for fast prototyping; nevertheless its performance can be increased by placing it inside water protecting foil.

Final Report: Laboratory Development of a High Capacity Gas-Fired Paper Dryer

Energy Technology Data Exchange (ETDEWEB)

Yaroslav Chudnovsky; Aleksandr Kozlov; Lester Sherrow

2005-09-30

Paper drying is the most energy-intensive and temperature-critical aspect of papermaking. It is estimated that about 67% of the total energy required in papermaking is used to dry paper. The conventional drying method uses a series of steam-heated metal cylinders that are required to meet ASME codes for pressure vessels, which limits the steam pressure to about 160 psig. Consequently, the shell temperature and the drying capacity are also limited. Gas Technology Institute together with Boise Paper Solutions, Groupe Laperrier and Verreault (GL&V) USA Inc., Flynn Burner Corporation and with funding support from the U.S. Department of Energy, U.S. natural gas industry, and Gas Research Institute is developing a high efficiency gas-fired paper dryer based on a combination of a ribbon burner and advanced heat transfer enhancement technique. The Gas-Fired Paper Dryer (GFPD) is a high-efficiency alternative to conventional steam-heated drying drums that typically operate at surface temperatures in the 300 deg F range. The new approach was evaluated in laboratory and pilot-scale testing at the Western Michigan University Paper Pilot Plant. Drum surface temperatures of more than 400 deg F were reached with linerboard (basis weight 126 lb/3000 ft2) production and resulted in a 4-5 times increase in drying rate over a conventional steam-heated drying drum. Successful GFPD development and commercialization will provide large energy savings to the paper industry and increase paper production rates from dryer-limited (space- or steam-limited) paper machines by an estimated 10 to 20%, resulting in significant capital costs savings for both retrofits and new capacity.

Active learning in higher education is important for learning efficacy and motivation. Accordingly, lectures that integrate strategies toward active learning, such as minute papers, debates, and collaborative learning, have become widely adopted. Minute papers facilitate communication among both teachers and students, and can be used as a tool for reviewing lectures. In the present study, we examined the effect of using minute papers on learning efficacy and motivation. To enhance the curriculum of the interdisciplinary course Yakugaku Nyumon, which consists of an omnibus lecture series and problem-based learning, minute papers with exercises were provided to applicants. In a follow-up questionnaire, students who used minute papers (S-USE) responded that they had a better understanding of the relationships, ranging from basic to clinical subject matter, than students who did not use such papers (S-NON). Using the Attention, Relevance, Confidence, and Satisfaction (ARCS) model questionnaire to measure study motivation, S-USE scored higher for some questionnaires than S-NON. This finding indicates that minute papers promoted learning motivation among students taking the Yakugaku Nyumon course. In regular examinations, the average score of S-USE was also statistically higher than that of S-NON. These results demonstrate that minute papers possibly encouraged students to actively review the lectures, thereby increasing both learning efficacy and motivation. This study shows that through promoting active, self-learning, minute papers are suitable for improving curricular strategies in subjects that rely on passive learning methods.

Contemporary German abounds in doubtful cases where linking elements alternate with zero elements, such as Seminar(+s?+)arbeit 'term paper', Respekt(+s?+)person 'person who commands respect'. This variation indicates a profound language change in the course of which the linking +s+ has spread continuously since Early New High German and is replacing the zero element more and more often. Today, +s+ is the most productive, progressive and most frequently occurring linking element. In this paper...

Bisphenol A and its structural analogues in household waste paper.

Bisphenol A (BPA) is an industrial chemical produced in large volumes. Its main use is associated with polycarbonate plastic, epoxy resins and thermal paper. In contrast to other applications, thermal paper contains BPA in its un-reacted form as an additive, which is subjected to migration. Receiving a significant amount of attention from the scientific community and beyond, due to its controversial endocrine-disrupting effects, the industry is attempting to substitute BPA in variety of applications. Alternative phenolic compounds have been proposed for use in thermal paper; however, information to what extent BPA alternatives have been used in paper is sparse. The aim of the present work was to quantify BPA and its alternatives (bisphenol S (BPS), bisphenol E (BPE), bisphenol B (BPB), 4-cumylphenol (HPP) and bisphenol F (BPF)) in waste paper and board from Danish households, thermal paper receipts, non-carbon copy paper and conventional printer paper. BPA was found in all waste paper samples analysed, while BPS was identified in 73% of them. Only BPB was not identified in any of the samples. BPA and BPS were found in the majority of the receipts, which contained no measurable concentrations of the remaining alternatives. Although receipts showed the highest concentrations of BPA and BPS, office paper, flyers and corrugated boxes, together with receipts, represented the major flux of the two compounds in waste paper streams.

2016-05-15

A novel protein immobilization method based on plasma treatment of paper on the low-cost paper-based immunodevice was established in this work. By using a benchtop plasma cleaner, the paper microzone was treated by oxygen plasma treatment for 4 min and then the antibody can be directly immobilized on the paper surface. Aldehyde group was produced after the plasma treatment, which can be verified from the fourier transform infrared spectroscopy (FT-IR) spectra and x-ray photoelectron spectroscopy (XPS) spectra. By linked to aldehyde group, the antibody can be immobilized on the paper surface without any other pretreatment. A paper-based immunodevice was introduced here through this antibody immobilization method. With sandwich chemiluminescence (CL) immunoassay method, the paper-based immunodevice was successfully performed for carcinoembryonic antigen (CEA) detection in human serum with a linear range of 0.1-80.0 ng/mL. The detection limit was 0.03 ng/mL, which was 30 times lower than the clinical CEA level. Comparing to the other protein immobilization methods on paper-based device, this strategy was faster and simpler and had potential applications in point-of-care testing, public health and environmental monitoring.

Justification and Persuasion about Cloning: Arguments in Hwang's Paper and Journalistic Reported Versions

Science.gov (United States)

Jiménez-Aleixandre, María Pilar; Federico-Agraso, Marta

2009-05-01

We examine the argumentative structure of Hwang et al.’s (2004) paper about human somatic cell nuclear transfer (SCNT, or ‘therapeutic cloning’), contrasted with four Journalistic Reported Versions (JRV) of it, and with students’ summaries of one JRV. As the evaluation of evidence is one of the critical features of argumentation (Jiménez-Aleixandre 2008), the analysis focuses on the use of evidence, drawing from instruments to analyze written argumentation (Kelly et al. 2008) and from studies about the structure of empirical research reports (Swales 2001). The objectives are: 1) To examine the use of evidence and the argumentative structure of Hwang et al.’s Science, 303: 1669-1674 (2004) original paper in terms of the criteria: a) pertinence of the evidence presented to the claims; b) sufficiency of the evidence for the purpose of supporting the claims; and c) coordination of the evidence across epistemic levels. 2) To explore how the structure of Hwang’s paper translates into the JRV and into university students’ perceptions about the evidence supporting the claims. The argumentative structure of Hwang’s paper is such that its apparently ostensible main claim about NT constitutes a justification for a second claim about its therapeutic applications, for which no evidence is offered. However, this second claim receives prominent treatment in the JRV and in the students’ summaries. Implications for promoting critical reading in the classroom are discussed.

Batlló, J.; Stich, D.; Macià, R.; Morales, J.

2009-04-01

On the night of 5th July 1930 a damaging earthquake struck the town of Montilla (near Córdoba, S-Spain) and its surroundings. Magnitude estimation for this earthquake is M=5, and its epicentral intensity has been evaluated as VIII (MSK). Even it is an earthquake of moderate size, it is the largest one in-strumentally recorded in this region. This makes this event of interest for a better definition of the regional seismicity. For this reason we decided to study a new its source from the analysis of the available contemporary seismograms and related documents. A total of 25 seismograms from 11 seismic stations have been collected and digitized. Processing of some of the records has been difficult because they were obtained from microfilm or contemporary reproductions on journals. Most of them are on smoked paper and recorded at regional distances. This poses a good opportunity to test the limits of the use of such low frequency - low dynamics recorded seismograms for the study of regional events. Results are promising: Using such regional seismograms the event has been relocated, its magnitude recalculated (Mw 5.1) and inversion of waveforms to elucidate its focal mechanism has been performed. We present the results of this research and its consequences for the regional seismicity and we compare them with present smaller earthquakes occurred in the same place and with the results obtained for earthquakes of similar size occurred more to the East on 1951.

Bisphenol A and replacements in thermal paper: A review.

Science.gov (United States)

Björnsdotter, Maria K; de Boer, Jacob; Ballesteros-Gómez, Ana

2017-09-01

Thermal paper contains potentially toxic compounds such as bisphenol A (BPA), which is used as a color developer. BPA has been reported in thermal paper in concentrations up to 42,600 μg g -1 . The exposure to BPA via dermal transfer has been recently discussed as a significant contribution to the overall human exposure and the estimated daily intake (EDI) has been reported up to 218 μg d -1 . BPA has been also detected in recycled paper with concentrations up to 46 μg g -1 . Due to the fact that BPA is a known endocrine disruptor and migrates from materials, regulatory restrictions have been established to prevent risks for the human health. As a consequence, structural analogues, such as bisphenol S (BPS) have been introduced into the market. Little is known about the presence and toxicity of these emerging replacements, and concern has risen about them. The present review gives an overview of the occurrence and levels of BPA and replacements in thermal paper. BPA is still the most common color developer found in thermal paper, followed by BPS. The analytical methods used for quantification of BPA and BPA replacements in paper products are also reviewed. BPA is transferred from thermal paper products to the finger pads upon handling it. Paper-skin transfer followed by penetration of BPA depends on conditions (e.g. greasiness of fingers and use of hand cream). It is, however, still debated whether thermal paper as a source for human exposure contributes significantly to the overall internal BPA exposure. Copyright © 2017 Elsevier Ltd. All rights reserved.

Fibrous Fillers to Manufacture Ultra High Ash/Performance Paper

Energy Technology Data Exchange (ETDEWEB)

Dr. VIjay K. Mathur

2009-04-30

The paper industry is one of the largest users of energy and emitters of CO2 in the US manufacturing industry. In addition to that, it is facing tremendous financial pressure due to lower cost imports. The fine paper industry has shrunk from 15 million tons per year production to 10 million tons per year in the last 5 years. This has resulted in mill closures and job loses. The AF&PA and the DOE formed a program called Agenda 2020 to help in funding to develop breakthrough technologies to provide help in meeting these challenges. The objectives of this project were to optimize and scale-up Fibrous Fillers technology, ready for commercial deployment and to develop ultra high ash/high performance paper using Fibrous Fillers. The goal was to reduce energy consumption, carbon footprint, and cost of manufacturing paper and related industries. GRI International (GRI) has been able to demonstrate the techno - economic feasibility and economic advantages of using its various products in both handsheets as well as in commercial paper mills. GRI has also been able to develop sophisticated models that demonstrate the effect of combinations of GRI's fillers at multiple filler levels. GRI has also been able to develop, optimize, and successfully scale-up new products for use in commercial paper mills.

2018-01-01

Citation analysis represents one of the best currently available methods for quantifying the impact of articles. Bibliometric studies list the ''best sellers'' in a single field of interest. The purpose of the present study was to identify and analyze the most frequently cited papers in dry eye research that may be of high interest for researchers and clinicians. We reviewed the database of the Institute for Scientific Information to identify articles published from 1900 to September 2016. All dry eye articles published in 59 ophthalmology journals were identified. The top 100 articles were selected for further analysis of authorship, source journal, number of citations, citation rate, geographic origin, article type, and level of evidence. The 100 most-cited articles were published between 1983 and 2011, with most of them in the 2000s. The number of citations per article ranged from 96 to 610, and was greatest for articles published in the 2000s. Each of these articles was published in one of 15 journals. Most articles represented Level-III evidence, followed by Levels II and I. The present study focusing on dry eye research revealed that 55% of the most-cited articles came from the U.S. and 18% from Japan. Diagnostics and therapy were the areas of focus of most of the clinical articles; 13% of the most cited papers were review articles. This analysis provides researchers and clinicians with a detailed overview on the most cited dry eye papers over the past decades. Copyright © 2017 Elsevier Inc. All rights reserved.

The Cyprus Coal Co. introduced the use of computer-aided design in planning and mapping operations at the company's Star Point No. 2 mine located south of Price, Utah and at the Orchard Valley mine near Craig, Colorado. CAD software is installed on a VAX 11/780 computer system. The process of converting large mine maps from paper to CAD files is described - the maps had to be broken down into layers. The CAD system has also introduced direct savings in mine planning and coal production by reducing engineering and surveying time at the mines and allowing a cost-effective response to government regulatory demands. 4 figs.

Optimization of Paper Discoloration via Pyrolysis Using Lasers

KAUST Repository

Alhashem, Mayadah M.

2017-04-01

Printing ink is a main component of the modern printer, and it has always been throughout the history of printing. Ink and toners are expensive replaceable components that inkjet and laser printers cannot function without. The digital printing industry, which is majorly composed of monochrome printing, is expected to increase by 225% by 2024 from a 2013 baseline (Smithers et al., 2014). Expenses aside, toner cartridges and ink cartridges pose an overlooked threat to the environment. Manufacturing, packaging, transporting, and waste disposal of printer ink and toners result in carbon dioxide emissions. The complete elimination of ink in monochrome printing is potentially viable with the patented new discoloration technique. The patent studies a discoloration method by carbonizing a paper’s surface (Alhashem et al., 2015). The printing method optimizes surface paper pyrolysis via laser heating. The aim is obtaining the darkest possible shade without compromising paper quality. The challenge is in creating a printed area from the paper material itself, rather than depositing ink on paper. A 75-watt CO2 laser engraving machine emitting a 10.6 μm wavelength beam for heating is used with low power settings to carbonize a fraction of the paper surface. The carbonization is essentially a combustion reaction. Solid fuel burns in three stages: drying, devolatilization (pyrolysis, or distillation phase), and lastly, the char (charcoal) combustion. These stages are driven by heat from the CO2 laser. Moving the laser rapidly above the paper surface arrests the reaction at the second stage, after the formation of blackened char. The control variables in the experimental method are laser power, speed, and the vertical position that affects the laser intensity. Computer software controls these variables. The discoloration of paper is quantified by measuring the light absorptivity using a UV-Vis-IR Spectrometer.

During the last 10 years the European Medicines Agency (EMA) organized a number of workshops on modeling and simulation, working towards greater integration of modeling and simulation (M&S) in the development and regulatory assessment of medicines. In the 2011 EMA - European Federation of Pharmaceutical Industries and Associations (EFPIA) Workshop on Modelling and Simulation, European regulators agreed to the necessity to build expertise to be able to review M&S data provided by companies in their dossier. This led to the establishment of the EMA Modelling and Simulation Working Group (MSWG). Also, there was agreement reached on the need for harmonization on good M&S practices and for continuing dialog across all parties. The MSWG acknowledges the initiative of the EFPIA Model-Informed Drug Discovery and Development (MID3) group in promoting greater consistency in practice, application, and documentation of M&S and considers the paper is an important contribution towards achieving this objective. © 2017 The Authors CPT: Pharmacometrics & Systems Pharmacology published by Wiley Periodicals, Inc. on behalf of American Society for Clinical Pharmacology and Therapeutics.

Two-step activation of paper batteries for high power generation: design and fabrication of biofluid- and water-activated paper batteries

Science.gov (United States)

Lee, Ki Bang

2006-11-01

Two-step activation of paper batteries has been successfully demonstrated to provide quick activation and to supply high power to credit card-sized biosystems on a plastic chip. A stack of a magnesium layer (an anode), a fluid guide (absorbent paper), a highly doped filter paper with copper chloride (a cathode) and a copper layer as a current collector is laminated between two transparent plastic films into a high power biofluid- and water-activated battery. The battery is activated by two-step activation: (1) after placing a drop of biofluid/water-based solution on the fluid inlet, the surface tension first drives the fluid to soak the fluid guide; (2) the fluid in the fluid guide then penetrates into the heavily doped filter paper with copper chloride to start the battery reaction. The fabricated half credit card-sized battery was activated by saliva, urine and tap water and delivered a maximum voltage of 1.56 V within 10 s after activation and a maximum power of 15.6 mW. When 10 kΩ and 1 KΩ loads are used, the service time with water, urine and saliva is measured as more than 2 h. An in-series battery of 3 V has been successfully tested to power two LEDs (light emitting diodes) and an electric driving circuit. As such, this high power paper battery could be integrated with on-demand credit card-sized biosystems such as healthcare test kits, biochips, lab-on-a-chip, DNA chips, protein chips or even test chips for water quality checking or chemical checking.

Pencil-on-Paper Capacitors for Hand-Drawn RC Circuits and Capacitive Sensing

Directory of Open Access Journals (Sweden)

Jonathan E. Thompson

2017-01-01

Full Text Available Electronic capacitors were constructed via hand-printing on paper using pencil graphite. Graphite traces were used to draw conductive connections and capacitor plates on opposing sides of a sheet of standard notebook paper. The paper served as the dielectric separating the plates. Capacitance of the devices was generally < 1000 pF and scaled with surface area of the plate electrodes. By combining a pencil-drawn capacitor with an additional resistive pencil trace, an RC low-pass filter was demonstrated. Further utility of the pencil-on-paper devices was demonstrated through description of a capacitive force transducer and reversible chemical sensing. The latter was achieved for water vapor when the hygroscopic cellulose matrix of the paper capacitor’s dielectric adsorbed water. The construction and demonstration of pencil-on-paper capacitive elements broadens the scope of paper-based electronic circuits while allowing new opportunities in the rapidly expanding field of paper-based sensors.

Radioactive Scrap Metal (RSM) recycling: A doe white paper

International Nuclear Information System (INIS)

Chatterjee, S.; Moore, H.H.; Ghoshal, A.

1992-01-01

An effective White Paper on recycling radioactive scrap metals has been drafted at the request of the U.S. Department of Energy (DOE) recently. The paper has received the praise and commendation of the DOE's Director of Environmental Management. However, obstructionist posturing by the petty bureaucrats in DOE continues to plague the meaningful implementation of RSM recycling. The key findings of the White Paper study and its major recommendations have discussed in this paper. The study indicates that several technologies, such as melt refining and electro refining, are currently available for surface and volume decontamination of metals. The unit cost of decontamination was found to vary from $700 to $400/ton; recycling of most low-contaminated metals can therefore be cost-effective vis-a vis the average cost of low-level radioactive wastes disposal of %400 to $2800/ton. Major recycling demonstration projects with emphasis on restricted RSM reuse options have been recommended. Volume contamination standard for unrestricted release should be established only after adequate studies of health effects and scientific/industrial effects of RSM reuse has been conducted by the Environmental Protection Agency (EPA) and the Nuclear Regulatory Commission (NRC). Some of the significant technical data developed during this study have also been briefly discussed in this paper. (author)

Cloud-supported preservation of digital papers: A solution for special collections?

2016-01-01

Full Text Available Computers and other digital communication media have replaced paper and pencil from the writer’s desk. This development has confronted special collections with a problem, as digital papers are difficult to process using established digital preservation strategies, because of their individual and unique nature. According to the proposal suggested in this paper, the creators should instead be involved in the preservation process, and special collections should integrate pre-custodial forms of curation within their range of tasks. The article outlines the use of a cloud architecture as a suitable instrument for accomplishing this task. The benefits and the prospects for such a collection cloud are exposed and discussed.

out at the European Solar Test Installation at Ispra in Italy. After describing the measurement methods, the authors discuss at length the calculations of measurement uncertainty. This leads to a rigorous discussion of relative uncertainties from measurement parameters. Uncertainties arise from a range of parameters that include small contributions from electrical, temperature and fill factor parameters. But the greatest arises from uncertainties both in the optical source and in the reference cell. As a consequence, the authors make a convincing case both for identifying the sources of uncertainty and for reducing overall uncertainties from +/-2.6% to below +/-2%. The conclusions are concise, and the paper is rounded off with a list of 34 references with several papers cited from 2005 onwards. This paper was rated as excellent by external referees, and has been downloaded several hundred times since its publication. It is one of 30 papers nominated this year in the Measurement Science category, and gained most votes from those short-listed.

The management of radioactive waste is one of the most serious environmental problems facing Canadians. From the early industrial uses of radioactive material in the 1930s to the development of nuclear power reactors and the medical and experimental use of radioisotopes today, there has been a steady accumulation of waste products. Although the difficulties involved in radioactive waste management are considerable, responsible solutions are possible. This paper will discuss low-level radioactive waste, including its production, the amounts in storage, the rate of waste accumulation and possible strategies for its management. (author). 2 figs

I Kalfas and Reza S Abhari Laboratory for Energy Conversion, Department of Mechanical and Process Engineering, ETH Zurich, Zurich, Switzerland and Department of Mechanical Engineering, Aristotle University of Thessaloniki, Greece The paper [2] describes the development of a probe for measuring time-resolved entropy fluctuations. The technique was developed for use in turbomachinery applications where knowledge of the unsteady entropy in the wake of a rotating blade row can provide significant insight into the loss (dissipation) generation mechanisms. There is no direct method to measure entropy; hence the authors use an approach where the stagnation pressure and stagnation temperature are measured on the same probe. The stagnation, or 'total', pressure has been the subject of several of the authors' papers in the last few years. The more significant challenge was the time-resolved measurement of total temperature. The high Mach numbers present in the flows of interest lead to significant temperature gradients in the probe itself which contaminate this type of measurement. The paper describes a novel probe design along with a detailed heat transfer calculation and uncertainty analysis.

Bibliometric review of the literature. To analyze and quantify the most frequently cited papers in lumbar spine surgery and to measure their impact on the entire lumbar spine literature. Lumbar spine surgery is a dynamic and complex field. Basic science and clinical research remain paramount in understanding and advancing the field. While new literature is published at increasing rates, few studies make long-lasting impacts. The Thomson Reuters Web of Knowledge was searched for citations of all papers relevant to lumbar spine surgery. The number of citations, authorship, year of publication, journal of publication, country of publication, and institution were recorded for each paper. The most cited paper was found to be the classic paper from 1990 by Boden et al that described magnetic resonance imaging findings in individuals without back pain, sciatica, and neurogenic claudication showing that spinal stenosis and herniated discs can be incidentally found when scanning patients. The second most cited study similarly showed that asymptomatic patients who underwent lumbar spine magnetic resonance imaging frequently had lumbar pathology. The third most cited paper was the 2000 publication of Fairbank and Pynsent reviewing the Oswestry Disability Index, the outcome-measure questionnaire most commonly used to evaluate low back pain. The majority of the papers originate in the United States (n=58), and most were published in Spine (n=63). Most papers were published in the 1990s (n=49), and the 3 most common topics were low back pain, biomechanics, and disc degeneration. This report identifies the top 100 papers in lumbar spine surgery and acknowledges those individuals who have contributed the most to the advancement of the study of the lumbar spine and the body of knowledge used to guide evidence-based clinical decision making in lumbar spine surgery today. 3.

Taylor, H.W.; Singh, B.

1993-01-01

The radioactivity of fine papers has been studied through γ-ray spectroscopy with an intrinsic Ge detector. Samples of paper from European and North American sources were found to contain very different amounts of 226 Ra and 232 Th. The processes which introduce radionuclides into paper are discussed. The radioactivity from fine papers makes only a small contribution to an individual's annual radiation dose; nevertheless it is easily detectable and perhaps, avoidable. (Author)

2018-04-01

In our contemporary world, while part of the fibers used in the paper industry is obtained from primary fibers such as wood and agricultural plants, the rest is obtained from secondary fibers from waste papers. To manufacture paper with high optical quality from fibers of recycled waste papers, these papers require deinking and bleaching of fibers at desired levels. High efficiency in removal of ink from paper mass during recycling, and hence deinkability, are especially crucial for the optical and printability quality of the ultimate manufactured paper. In the present study, deinkability and printability performance of digitally printed paper with toner or inkjet ink were compared for the postrecycling product. To that end, opaque 80 g/m 2 office paper was digitally printed under standard printing conditions with laser toner or inkjet ink; then these sheets of paper were deinked by a deinking process based on the INGEDE method 11 p. After the deinking operation, the optical properties of the obtained recycled handsheets were compared with unprinted (reference) paper. Then the recycled paper was printed on once again under the same conditions as before with inkjet and laser printers, to monitor and measure printing color change before and after recycling, and differences in color universe. Recycling and printing performances of water-based inkjet and toner-based laser printed paper were obtained. The outcomes for laser-printed recycled paper were better than those for inkjet-printed recycled paper. Compared for luminosity Y, brightness, CIE a* and CIE b* values, paper recycled from laser-printed paper exhibited higher value than paper recycled from inkjet-printed paper.

Measuring incident light on grape clusters using photosensitive paper and image analysis

International Nuclear Information System (INIS)

Price, S.F.; Schuette, M.L.; Tassie, E.

1995-01-01

Digital imaging and analysis was used to quantify and characterize the light exposure patterns of photosensitive paper tubes placed in representative cluster positions in two grape (Vitis vinifera L.) canopies: a minimally pruned and a vertically trained canopy. Blue pixel values of the captured images had a negative correlation with the log of irradiance from an integrating quantum sensor (r2 = 0.9308). The spectral response of the photosensitive paper was not measured. Histograms of incident light distribution on individual paper tubes were developed using imaging software. Histograms were able to quantify the distribution of incident light on individual tubes and were clearly related to the tube's exposure in the canopy. Average population curves of pixel light distribution of 20 tubes in each canopy were able to differentiate the typical cluster light environment in the two canopies. Tubes in the minimally pruned canopy had a larger proportion of their surface exposed to irradiances > 50 micromoles.s-1 m-2 and 65% higher average irradiance than the vertical canopy. Image analysis of photosensitive paper appears to be a workable method to record the distribution of incident light in plant canopies and may have utility in a range of ecological studies

All-printed paper memory

KAUST Repository

Lien, Derhsien

2014-08-26

We report the memory device on paper by means of an all-printing approach. Using a sequence of inkjet and screen-printing techniques, a simple metal-insulator-metal device structure is fabricated on paper as a resistive random access memory with a potential to reach gigabyte capacities on an A4 paper. The printed-paper-based memory devices (PPMDs) exhibit reproducible switching endurance, reliable retention, tunable memory window, and the capability to operate under extreme bending conditions. In addition, the PBMD can be labeled on electronics or living objects for multifunctional, wearable, on-skin, and biocompatible applications. The disposability and the high-security data storage of the paper-based memory are also demonstrated to show the ease of data handling, which are not achievable for regular silicon-based electronic devices. We envision that the PPMDs manufactured by this cost-effective and time-efficient all-printing approach would be a key electronic component to fully activate a paper-based circuit and can be directly implemented in medical biosensors, multifunctional devices, and self-powered systems. © 2014 American Chemical Society.

Worlds Apart: Nam Le’s The Boat and Ali Alizadeh’s Transactions

Directory of Open Access Journals (Sweden)

Lachlan Brown

2015-05-01

Full Text Available This paper reads Ali Alizadeh’s transnational book of short stories (Transactions, 2013 as a curious and pointed response to the kind of literary internationalism seen in Nam Le’s The Boat (2008. Le’s work was first published in the same year as Alizadeh’s The New Angel (which was set during the Iranian revolution. There is a sense in which the spectacular success of Le’s book ‘overshadowed’ the publicity for Alizadeh’s novel in the year of its arrival. But Le’s also work contains a story about an American woman visiting Tehran, and his mimicry perhaps signifies a more problematic representational point of comparison. With this in mind, this paper examines Alizadeh’s Transactions exploring the ways in which Alizadeh’s brutally connected global vision is coded through certain aesthetic choices (including structural, tonal and descriptive that offer something very different to the artisanal and paratactic sensibility of The Boat.

Internet QoS provisioning gives rise to several challenging issues. This paper introduces a generic distributed QoS adaptive routing engine (DQARE architecture based on OSPFxQoS. The innovation of the proposed work in this paper is its undependability on the used QoS architectures and, moreover, splitting of the control strategy from data forwarding mechanisms, so we guarantee a set of absolute stable mechanisms on top of which Internet QoS can be built. DQARE architecture is furnished with three relevant traffic control schemes, namely, service differentiation, QoS routing, and traffic engineering. The main objective of this paper is to (i provide a general configuration guideline for service differentiation, (ii formalize the theoretical properties of different QoS routing algorithms and then introduce a QoS routing algorithm (QOPRA based on dynamic programming technique, and (iii propose QoS multipath forwarding (QMPF model for paths diversity exploitation. NS2-based simulations proved the DQARE superiority in terms of delay, packet delivery ratio, throughput, and control overhead. Moreover, extensive simulations are used to compare the proposed QOPRA algorithm and QMPF model with their counterparts in the literature.

It is worth 10 million working hours a year to have your toilet paper folded?

Science.gov (United States)

Ljung, Rickard; Ljung, Hedvig; Ljung, Harald

2016-01-01

From our experience the toilet paper is folded in the bathrooms in rooms in branded hotels. We aimed to study the total time yearly spent in the world on folding hotel toilet paper. Three investigators clocked 60 folding toilet paper events and calculated the mean time. The mean folding time was 5.73 s (interquartile range 4.50-6.56). Using the calculated extra time it takes to fold the toilet paper and the number of hotel nights spent we estimated the total time spent in the world each year to fold the toilet paper. For sensitivity analyses we used different assumptions on number of hotel beds, occupancy rate and folding time. Assuming an extra 10 s spent on folding toilet paper, approximately 10 million hours are globally spent on folding toilet paper every year. This corresponds to more than 5000 man-years of work. In a hotel with yearly full coverage of 200 beds skipping folding the toilet paper corresponds to around 200 h of time that could be spent elsewhere. To take away unnecessary duties from hotel room cleaners would increase their health and well-being and save time that could be better spent. Is it really defendable and appropriate that someone else has spent time on folding the toilet paper you are just about to use?

Commented Portuguese translation of Guillaume’s paper of 1896 about the temperature of space

2014-11-01

Full Text Available We present a complete Portuguese translation of the 1896 paper by Charles Édouard Guillaume (1861-1928 about the temperature of interstellar space. The importance of this work is that it is the oldest estimate known to us of the temperature acquired by a body which is in interstellar space far away from other stars. This temperature would be due to an equilibrium state in which the radiation received by this body from the stars around it would be equal to the radiation emitted by this body. This estimative happened prior to the birth of George Gamow (1904-1968 who is considered erroneously in many textbooks as being the first person to have predicted this temperature.

High-solids loading enzymatic hydrolysis of waste papers for biofuel production

International Nuclear Information System (INIS)

Wang, Lei; Templer, Richard; Murphy, Richard J.

2012-01-01

Highlights: ► Waste papers have great potential as a feedstock for bioethanol production. ► A wet blending step would significantly enhance enzymatic hydrolysis efficiency. ► High-solids loading saccharification was performed successfully on waste papers. ► Saccharification data were from four types of paper and two enzyme alternatives. ► Enzymatic hydrolysis kinetic models were validated by experimental data. -- Abstract: Waste papers (newspaper, office paper, magazines and cardboard in this study) with 50–73% (w/w oven dry weight) carbohydrate contents have considerable potential as raw materials for bioethanol production. A particle size reduction step of wet blending prior to enzymatic hydrolysis of newspaper was found to increase the glucan conversion efficiency by up to 10%. High-solids loading hydrolysis at 15% (w/w) of four types of paper using two enzyme alternatives, Celluclast 1.5L supplemented with Novozyme 188 and Cellic Ctec 1 (Novozymes A/S, Demark), at various enzyme concentrations were successfully performed in a lab-scale overhead-stirred reactor. This work has identified the relative saccharification performance for the four types of paper and shows office paper and cardboard to be more suitable for producing bioethanol than newspaper or magazine paper. The experimental data were also very well described by a modified, simple three parameter glucan and xylan hydrolysis model. These findings provide the possibility for incorporating this validated kinetic model into process designs required for commercial scale bioethanol production from waste paper resources.

The Precision Array for Probing the Epoch of Reionization (PAPER) was a first-generation 21 cm cosmology experiment with the specific goal of detecting the power spectrum of the 21 cm emission from the Epoch of Reionization. Analysis of PAPER data is still ongoing, but lessons learned from PAPER to date have played a critical role in designing the next-generation Hydrogen Epoch of Reionization Array (HERA) experiment. This article reviews five key design choices made by PAPER: use of a non-imaging configuration, redundancy, short baselines, small antenna elements, and a large instantaneous bandwidth. We describe the impact of these choices and the role they played in designing HERA.

Traditionally in superhydrophobic surfaces history, the focus has frequently settled on the use of complex processing methodologies using nonbiodegradable and costly materials. In light of recent events on lab-on-paper emergence, there are now some efforts for the production of superhydrophobic paper but still with little development and confined to the fabrication of flat devices. This work gives a new look at the range of possible applications of bioinspired superhydrophobic paper-based substrates, obtained using a straightforward surface modification with poly(hydroxybutyrate). As an end-of-proof of the possibility to create lab-on-chip portable devices, the patterning of superhydrophobic paper with different wettable shapes is shown with low-cost approaches. Furthermore, we suggest the use of superhydrophobic paper as an extremely low-cost material to design essential nonplanar lab apparatus, including reservoirs for liquid storage and manipulation, funnels, tips for pipettes, or accordion-shaped substrates for liquid transport or mixing. Such devices take the advantage of the self-cleaning and extremely water resistance properties of the surfaces as well as the actions that may be done with paper such as cut, glue, write, fold, warp, or burn. The obtained substrates showed lower propensity to adsorb proteins than the original paper, kept superhydrophobic character upon ethylene oxide sterilization and are disposable, suggesting that the developing devices could be especially adequate for use in contact with biological and hazardous materials.

Flexible sweat biosensors are of considerable current interest for the development of wearable smart miniature devices. In this work, we report a novel type of flexible and electrochemical sweat platform fabricated by depositing Cu submicron buds on freestanding graphene paper (GP) carrying MoS 2 nanocrystals monolayer for bio-functional detection of glucose and lactate. Quantitative analysis of glucose and lactate was carried out by using amperometric i-t method. Linear ranges were obtained between 5 and 1775 μM for glucose and 0.01-18.4 mM for lactate, and their corresponding limits of detection were 500 nM and 0.1 μM, respectively. The platform demonstrates fast response, good selectivity, superb reproducibility and outstanding flexibility, which enable its use for monitoring glucose and lactate in human perspiration. The strategy of structurally integrating 3D transition metal, 0D transition metal sulfide and 2D graphene will provide new insight into the design of flexible electrodes for sweat glucose and lactate monitoring and a wider range of applications in biosensing, bioelectronics, and lab-on-a-chip devices.

Spectral signature barcodes based on S-shaped Split Ring Resonators (S-SRRs

Directory of Open Access Journals (Sweden)

Herrojo Cristian

2016-01-01

Full Text Available In this paper, it is shown that S-shaped split ring resonators (S-SRRs are useful particles for the implementation of spectral signature (i.e., a class of radiofrequency barcodes based on coplanar waveguide (CPW transmission lines loaded with such resonant elements. By virtue of its S shape, these resonators are electrically small. Hence S-SRRs are of interest for the miniaturization of the barcodes, since multiple resonators, each tuned at a different frequency, are used for encoding purposes. In particular, a 10-bit barcode occupying 1 GHz spectral bandwidth centered at 2.5 GHz, with dimensions of 9 cm2, is presented in this paper.

The Alzheimer’s Disease Neuroimaging Initiative (ADNI) is an ongoing, longitudinal, multicenter study designed to develop clinical, imaging, genetic, and biochemical biomarkers for the early detection and tracking of Alzheimer’s disease (AD). The initial study, ADNI-1, enrolled 400 subjects with early mild cognitive impairment (MCI), 200 with early AD, and 200 cognitively normal elderly controls. ADNI-1 was extended by a 2-year Grand Opportunities grant in 2009 and by a competitive renewal, ADNI-2, which enrolled an additional 550 participants and will run until 2015. This article reviews all papers published since the inception of the initiative and summarizes the results to the end of 2013. The major accomplishments of ADNI have been as follows: (1) the development of standardized methods for clinical tests, magnetic resonance imaging (MRI), positron emission tomography (PET), and cerebrospinal fluid (CSF) biomarkers in a multicenter setting; (2) elucidation of the patterns and rates of change of imaging and CSF biomarker measurements in control subjects, MCI patients, and AD patients. CSF biomarkers are largely consistent with disease trajectories predicted by β-amyloid cascade (Hardy, J Alzheimer’s Dis 2006;9(Suppl 3):151–3) and tau-mediated neurodegeneration hypotheses for AD, whereas brain atrophy and hypometabolism levels show predicted patterns but exhibit differing rates of change depending on region and disease severity; (3) the assessment of alternative methods of diagnostic categorization. Currently, the best classifiers select and combine optimum features from multiple modalities, including MRI, [18F]-fluorodeoxyglucose-PET, amyloid PET, CSF biomarkers, and clinical tests; (4) the development of blood biomarkers for AD as potentially noninvasive and low-cost alternatives to CSF biomarkers for AD diagnosis and the assessment of α-syn as an additional biomarker; (5) the development of methods for the early detection of AD.

KAUST Repository

Cook, Benjamin

2011-12-07

This thesis represents a major contribution to wideband and high gain inkjet-printed antennas on paper. This work includes the complete characterization of the inkjet printing process for passive microwave devices on paper substrate as well as several ultra-wideband and high gain antenna designs. The characterization work includes the electrical characterization of the permittivity and loss tangent for paper substrate through 10 GHz, ink conductivity data for variable sintering conditions, and minimum feature sizes obtainable by today’s current inkjet processes for metallic nanoparticles. For the first time ever, inkjet-printed antennas are demonstrated that operate over the entire UWB band and demonstrate gains up to 8dB. This work also presents the first fractal-based inkjet-printed antennas with enhanced bandwidth and reduced production costs, and a novel slow wave log periodic dipole array which shows minimizations of 20% in width over conventional log periodic antennas.

Feasible Application Area Study for Linear Laser Cutting in Paper Making Processes

Science.gov (United States)

Happonen, A.; Stepanov, A.; Piili, H.

Traditional industry sectors, like paper making industry, tend to stay within well-known technology rather than going forward towards promising, but still quite new technical solutions and applications. This study analyses the feasibility of the laser cutting in large-scale industrial paper making processes. Aim was to reveal development and process related challenges and improvement potential in paper making processes by utilizing laser technology. This study has been carried out, because there still seems to be only few large-scale industrial laser processing applications in paper converting processes worldwide, even in the beginning of 2010's. Because of this, the small-scale use of lasers in paper material manufacturing industry is related to a shortage of well-known and widely available published research articles and published measurement data (e.g. actual achieved cut speeds with high quality cut edges, set-up times and so on). It was concluded that laser cutting has strong potential in industrial applications for paper making industries. This potential includes quality improvements and a competitive advantage for paper machine manufacturers and industry. The innovations have also added potential, when developing new paper products. An example of these kinds of products are ones with printed intelligence, which could be a new business opportunity for the paper industries all around the world.

A Paper-Based Electrochromic Array for Visualized Electrochemical Sensing.

Zhang, Fengling; Cai, Tianyi; Ma, Liang; Zhan, Liyuan; Liu, Hong

2017-01-31

We report a battery-powered, paper-based electrochromic array for visualized electrochemical sensing. The paper-based sensing system consists of six parallel electrochemical cells, which are powered by an aluminum-air battery. Each single electrochemical cell uses a Prussian Blue spot electrodeposited on an indium-doped tin oxide thin film as the electrochromic indicator. Each electrochemical cell is preloaded with increasing amounts of analyte. The sample activates the battery for the sensing. Both the preloaded analyte and the analyte in the sample initiate the color change of Prussian Blue to Prussian White. With a reaction time of 60 s, the number of electrochemical cells with complete color changes is correlated to the concentration of analyte in the sample. As a proof-of-concept analyte, lactic acid was detected semi-quantitatively using the naked eye.

This study assesses the impact of 23 energy-efficiency measures that could be applied in China's pulp and paper industry. We analyze the fuel- and electricity-efficiency improvement potential of these technologies for the year 2010 using a bottom-up conservation supply curve (CSC) model. The fuel CSC model shows that the cost-effective fuel efficiency improvement potential for China's pulp and paper industry is 179.6 PJ, and the total technical fuel-savings potential is 254.3 PJ. These figures represent 26.8 percent and 38.0 percent, respectively, of total fuel used in China’s pulp and paper industry in 2010. The CO₂ emissions reduction potential associated with ii the cost-effective fuel savings is 16.9 Mt CO₂, and the total technical potential for CO₂ emissions reduction is 24.2 Mt CO₂. The electricity CSC model shows that the total technical electricity-efficiency potential to 2,316 gigawatt-hours (GWh) or 4.3 percent of total electricity use in the pulp and paper industry in 2010. All of the electricity-efficiency potential is cost effective. The CO₂ emissions reduction potential associated with the total electricity savings is 1.8 Mt CO₂. Sensitivity analyses for adoption rate, discount rate, electricity and fuel prices, investment costs, and the energy savings from each measure show that these parameters have significant influence on the results. Therefore, the results presented in this report should be interpreted with caution.

There are wide spread bacterial contamination issues on various paper products, such as paper towels hanging in sink splash zones or those used to clean surfaces, filter papers used in water and air purifying systems, and wrappings used in the food industry; such contamination may lead to the potential spread of bacteria and consequent severe health concerns. In this study, selenium nanoparticles were coated on normal paper towel surfaces through a quick precipitation method, introducing antibacterial properties to the paper towels in a healthy way. Their effectiveness at preventing biofilm formation was tested in bacterial assays involving Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus epidermidis. The results showed significant and continuous bacteria inhibition with about a 90% reduction from 24 to 72 hours for gram-positive bacteria including S. aureus and S. epidermidis. The selenium coated paper towels also showed significant inhibition of gram-negative bacteria like P. aeruginosa and E. coli growth at about 57% and 84%, respectively, after 72 hours of treatment. Therefore, this study established a promising selenium-based antibacterial strategy to prevent bacterial growth on paper products, which may lead to the avoidance of bacteria spreading and consequent severe health concerns.

A study to determine the feasibility of preparing ultrathin papers with a target weight of 3.5 g/m squared from polybenzimidazole (PBI) fibrids was undertaken. Small hand sheets of target weight were fabricated. They were light brown, low density materials with sufficient strength to be readily handleable. Characterization of these sheets included strength, fold endurance, thermal gravimetric analysis in air and nitrogen and photomicrographs. Two different batches of PBI fibrids were studied and differences in fabrication performance were noted. In neither case could target weight papers be prepared using conventional paper making techniques.

Liu, Qian; Xu, Chaoping; Liang, Heng

2017-12-01

We developed novel laser carved micro-crack (LCC) paper-based channels to significantly accelerate the liquid flow without an external pump. For the aqueous solutions they increased the flow velocity 59 times in 16% laser power-8 micro-cracks-LCC channel compared with it in solely-printed channels. All experimental data from both LCC and solely-printed channels were well-fitted by the time-distance quadratic trinomial that we developed on laser power and micro-crack number. We designed and fabricated T-junction microstructures of LCCs. Further, the microfluidic paper-based analytical device (μPAD) of LCC on dye mixing gradient and pH gradient were developed with the characteristics, fast self-acting transportation and high-performance mixing of liquid flows. In the dye mixing gradient the time cost was reduced from 2355s in the solely-printed one to only 123s in the five-stage of this LCC-μPAD. It was useful for quick and long-distance transferences through the multiple units of μPADs. Certainly, this LCC-μPAD was inexpensive, disposable, portable and applicable to resource-limited environments. Copyright © 2017 Elsevier B.V. All rights reserved.

Highlights: • We developed a paper-based SERS substrate by gravure and inkjet printing methods. • The S-RGO/AgNPs comoposite structure had higher SERS activity than the pure AgNPs. • The Raman enhancement factor of S-RGO/AgNPs substrate was calculated to be 10{sup 9}. • The paper-based substrate exhibited good reproducibility and long-term stability. - Abstract: Paper-based surface-enhanced Raman scattering (SERS) substrates receive a great deal of attention due to low cost and high flexibility. Herein, we developed an efficient SERS substrate by gravure printing of sulfonated reduced graphene-oxide (S-RGO) thin film and inkjet printing of silver nanoparticles (AgNPs) on weighing paper successively. Malachite green (MG) and rhodamine 6G (R6G) were chosen as probe molecules to evaluate the enhanced performance of the fabricated SERS-active substrates. It was found that the S-RGO/AgNPs composite structure possessed higher enhancement ability than the pure AgNPs. The Raman enhancement factor of S-RGO/AgNPs was calculated to be as large as 10{sup 9}. The minimum detection limit for MG and R6G was down to 10{sup −7} M with good linear responses (R{sup 2} = 0.9996, 0.9983) range from 10{sup −4} M to 10{sup −7} M. In addition, the S-RGO/AgNPs exhibited good uniformity with a relative standard deviation (RSD) of 7.90% measured by 572 points, excellent reproducibility with RSD smaller than 3.36%, and long-term stability with RSD less than 7.19%.

A simple and scalable direct laser machining process to fabricate MXene-on-paper coplanar microsupercapacitors is reported. Commercially available printing paper is employed as a platform in order to coat either hydrofluoric acid-etched or clay-like 2D Ti3C2 MXene sheets, followed by laser machining to fabricate thick-film MXene coplanar electrodes over a large area. The size, morphology, and conductivity of the 2D MXene sheets are found to strongly affect the electrochemical performance due to the efficiency of the ion-electron kinetics within the layered MXene sheets. The areal performance metrics of Ti3C2 MXene-on-paper microsupercapacitors show very competitive power-energy densities, comparable to the reported state-of-the-art paper-based microsupercapacitors. Various device architectures are fabricated using the MXene-on-paper electrodes and successfully demonstrated as a micropower source for light emitting diodes. The MXene-on-paper electrodes show promise for flexible on-paper energy storage devices. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Full Text Available A method for direct aniline interfacial polymerization on polyamideamine-epichlorohydrin (PAE-reinforced paper substrate is introduced in this paper. Cellulose-based papers with and without reinforcement were considered. The polyaniline (PANI-paper composites had surface resistivity lower than 100 Ω/sq after more than 3 polymerizations. Their mechanical strength and thermal stability were analyzed by tensile tests and thermogravimetric analysis (TGA. Fourier transform infrared (FTIR results revealed that there was strong interaction between NH groups in aniline monomers and OH groups in fibers, which did not disappear until after 3 polymerizations. Scanning electron microscopy (SEM and field emission (FE SEM images showed morphological differences between composites using reinforced and untreated base papers. Conductive composites made with PAE-reinforced base paper had both good thermal stability and good mechanical strength, with high conductivity and a smaller PANI amount.

Quantity and/or Quality? The Importance of Publishing Many Papers

Do highly productive researchers have significantly higher probability to produce top cited papers? Or do high productive researchers mainly produce a sea of irrelevant papers—in other words do we find a diminishing marginal result from productivity? The answer on these questions is important, as it may help to answer the question of whether the increased competition and increased use of indicators for research evaluation and accountability focus has perverse effects or not. We use a Swedish author disambiguated dataset consisting of 48.000 researchers and their WoS-publications during the period of 2008–2011 with citations until 2014 to investigate the relation between productivity and production of highly cited papers. As the analysis shows, quantity does make a difference. PMID:27870854

Full Text Available Biodegradable chitosan can be applied as a coating on the surface of kraft paper in order to improve its barrier properties against water vapor and air. The food packaging industry can benefit from the addition of chitosan to its current packaging, and in turn reduce pollution from plastic packaging plants. This paper discusses the film formation of chitosan, the permeability of paper coated with a chitosan layer, and the influence on the paper’s surface and barrier properties under different process conditions. SEM (scanning electron microscope, AFM (atomic force microscope, ATR-FTIR (Fourier transmission infrared spectroscope with attenuated total reflection, and PDA (penetration dynamics analysis were used to analyze the properties of chitosan’s film formation and permeability. A controlled experiment showed that the chitosan layer was smoother than the surface of the uncoated kraft paper, had better film formation, and that there was no chitosan penetration through the kraft paper. The barrier properties against water vapor were strongest when there was a higher concentration of chitosan solution at the optimum pH, stirring speed, and those with a thicker coating on the kraft paper.

HEPAP White Paper on planning for U.S. high-energy physics [High Energy Physics Advisory Panel

International Nuclear Information System (INIS)

2000-01-01

High-energy physicists seek to understand what the universe is made of, how it works, and where it has come from. They investigate the most basic particles and the forces between them. Experiments and theoretical insights over the past several decades have made it possible to see the deep connection between apparently unrelated phenomena, and to piece together more of the story of how a rich and complex cosmos could evolve from just a few kinds of elementary particles. The 1998 Subpanel of the High Energy Physics Advisory Panel (HEPAP) laid out a strategy for U.S. high-energy physics for the next decade. That strategy balanced exciting near-term opportunities with preparations for the most important discovery possibilities in the longer-term. Difficult choices were made to end several highly productive programs and to reduce others. This year HEPAP was charged to take the plan given in the Subpanel's report, understand it in the context of worldwide progress, and update it. In response to that charge, this White Paper provides an assessment of where we stand, states the next steps to take in the intermediate term, and serves as input for a longer range planning process involving a new HEPAP subpanel and high-energy physics community evaluation in 2001. Since the 1998 Subpanel, there have been important developments and a number of the Subpanel's recommendations have been implemented. Notably, construction of the B-factory at SLAC, the Main Injector at Fermilab, and the upgrade of CESR at Cornell have all been finished on schedule and on budget. We have gained great confidence in the performance of these accelerators and the associated detectors. The B-factory at SLAC is already operating above design luminosity and plans are in place to reach three times the design in the next few years. In addition, there have been major physics developments that lead us to believe that these completed projects are guaranteed to produce frontier physics results and have an

The Evolution of Paper Money

OpenAIRE

Levintal, Oren; Zeira, Joseph

2009-01-01

This paper tells the story of how paper money evolved as a result of lending by banks. While lending commodity money requires holding large reserves of commodity money to ensure liquidity, issuing convertible paper money reduces these costs significantly. The paper also examines the possibility of issuing inconvertible notes and shows that while they further reduce the cost of borrowing they also have adverse effects on the stability of the banking system. As a result, governments often inter...

Quality Of Life and Nursing: a Position Paper

Antigoni Fountouki

2010-01-01

Full Text Available Introduction: This paper presents a historical review of quality assurance in nursing with terminologicaldefinitions. General issues involving the evaluation of quality of care are discussed and key questions tackled.Aims: The aims of this paper were to critically discuss and analyze the essence of quality as a construct with highrelevance to nursing practice. Also, to look at quality through a series of important benchmark questions such aswho evaluates, who is the evaluated, what is evaluated, whose interests are involved.Methods: An online search in Medline, CINHAL, PsycINFO, ELIN, Embase, and the Cochrane Database ofSystematic Reviews was conducted. Retrieved studies were screened to meet certain inclusion criteria, i.e.relevance, significant meanings in correspondence with this paper’s aims and of interest to an international nursingreadership.Results: Data were abstracted from each paper and tabulated for further discussion and data synthesis. Nurses havebeen fervent supporters of quality assurance as it provides feedback to the profession about its practices andeffectiveness of care. The hospital, as an independent organization in the health care industry, sees nursing as theprovider closest to the consumer so is very concerned with the quality of nursing care. Nurses see through the lensof the customer and understand his or her wants and needs and therefore understand business better than otherproviders.Conclusions: The main conclusion of this position paper is that a major underlying reason for quality of careevaluation is the measurement of costs. As the goal for every successful manager is to minimise costs whilemaintaining quality. This equates nursing evaluation to the evaluation of a business model- a parallel which doesnot appeal to the caring profession of nursing.

Zhang, Zhiping; Xu, Wei; Manicke, Nicholas E.; Cooks, R. Graham; Ouyang, Zheng

2011-01-01

Paper spray is a newly developed ambient ionization method that has been applied for direct qualitative and quantitative analysis of biological samples. The properties of the paper substrate and spray solution have a significant impact on the release of chemical compounds from complex sample matrices, the diffusion of the analytes through the substrate, and the formation of ions for mass spectrometry analysis. In this study, a commercially available silica-coated paper was explored in an attempt to improve the analysis of therapeutic drugs in dried blood spots (DBS). The dichloromethane/isopropanol solvent has been identified as an optimal spray solvent for the analysis. The comparison was made with paper spray using chromatography paper as substrate with methanol/water as solvent for the analysis of verapamil, citalopram, amitriptyline, lidocaine and sunitinib in dried blood spots. It has been demonstrated the efficiency of recovery of the analytes was notably improved with the silica coated paper and the limit of quantitation (LOQ) for the drug analysis was 0.1 ng mL−1 using a commercial triple quadrupole mass spectrometer. The use of silica paper substrate also resulted in a sensitivity improvement of 5-50 fold in comparison with chromatography papers, including the Whatmann ET31 paper used for blood card. Analysis using a handheld miniature mass spectrometer Mini 11 gave LOQs of 10~20 ng mL−1 for the tested drugs, which is sufficient to cover the therapeutic ranges of these drugs. PMID:22145627

Freestanding bucky paper with high strength from multi-wall carbon nanotubes

International Nuclear Information System (INIS)

Li, Zhonglai; Xu, Ju; O'Byrne, Justin P.; Chen, Lan; Wang, Kaixue; Morris, Michael A.; Holmes, Justin D.

2012-01-01

Bucky papers have been investigated by some research groups, however, due to different qualities of carbon nanotubes used, various results of strength and electronic properties were reported in the literatures. In this article, the effects of carbon nanotubes synthesized over different catalysts on the qualities of bucky papers were systemically investigated. Multi-wall carbon nanotubes were synthesized over a series of MgO supported catalysts with different weight ratios of Mo and Co. As the ratios of Mo/Co in the catalysts were increased from 0 to 3, the yields of carbon nanotubes were enhanced from 7 wt% to 400 wt%. However, the yield enhancement of carbon nanotubes was achieved at the expense of higher proportion of structural defects within carbon nanotubes, which has been proved by Raman spectroscopy and thermogravimetry analysis. It was demonstrated that the tensile strength of bucky paper composed of numerous MCNTs bundles strongly depends on the structure of carbon nanotubes used. By optimizing reaction conditions, a bucky paper with high strain up to 15.36 MPa and electrical conductivity of 61.17 S cm −1 was obtained by Supercritical Fluid (SCF) drying technique. -- Highlights: ► Multi-wall carbon nanotube bucky paper. ► Structural defects of carbon nanotubes. ► CoMo catalyst. ► Tensile strength of bucky paper.

Clarivate Analytics's Web of Science (WoS) is the world's leading scientific citation search and analytical information platform. It is used as both a research tool supporting a broad array of scientific tasks across diverse knowledge domains as well as a dataset for large-scale data-intensive studies. WoS has been used in thousands of published academic studies over the past 20 years. It is also the most enduring commercial legacy of Eugene Garfield. Despite the central position WoS holds in contemporary research, the quantitative impact of WoS has not been previously examined by rigorous scientific studies. To better understand how this key piece of Eugene Garfield's heritage has contributed to science, we investigated the ways in which WoS (and associated products and features) is mentioned in a sample of 19,478 English-language research and review papers published between 1997 and 2017, as indexed in WoS databases. We offered descriptive analyses of the distribution of the papers across countries, institutions and knowledge domains. We also used natural language processingtechniques to identify the verbs and nouns in the abstracts of these papers that are grammatically connected to WoS-related phrases. This is the first study to empirically investigate the documentation of the use of the WoS platform in published academic papers in both scientometric and linguistic terms.

2014-09-22

Specialty paper (e.g. cigarette paper and battery diaphragm paper) requires extremely high strength properties. The addition of strength agents plays an important role in increasing strength properties of paper. Nanocrystalline cellulose (NCC), or cellulose whiskers, has the potential to enhance the strength properties of paper via improving inter-fibers bonding. This paper was to determine the potential of using carboxylated nanocrystalline cellulose (CNCC) to improve the strength properties of paper made of cellulosic fiber or poly (vinyl alcohol) (PVA) fiber. The results indicated that the addition of CNCC can effectively improve the strength properties. At a CNCC dosage of 0.7%, the tear index and tensile index of the cellulosic paper reached the maximum of 12.8 mN m2/g and 100.7 Nm/g, respectively. More importantly, when increasing the CNCC dosage from 0.1 to 1.0%, the tear index and tensile index of PVA fiber paper were increased by 67.29%, 22.55%, respectively. Copyright © 2014 Elsevier Ltd.

Elgot, Calvin C

1982-01-01

Cal Elgot was a very serious and thoughtful researcher, who with great determi­ nation attempted to find basic explanations for certain mathematical phenomena­ as the selection of papers in this volume well illustrate. His approach was, for the most part, rather finitist and constructivist, and he was inevitably drawn to studies of the process of computation. It seems to me that his early work on decision problems relating automata and logic, starting with his thesis under Roger Lyndon and continuing with joint work with Biichi, Wright, Copi, Rutledge, Mezei, and then later with Rabin, set the stage for his attack on the theory of computation through the abstract treatment of the notion of a machine. This is also apparent in his joint work with A. Robinson reproduced here and in his joint papers with John Shepherdson. Of course in the light of subsequent work on decision problems by Biichi, Rabin, Shelah, and many, many others, the subject has been placed on a completely different plane from what it was whe...

2007-01-01

In order to perform experimental measurements for evaluation of imaging device's performance, data acquisition technique, and clinical images on scintigraphic imaging, many kinds of phantoms are employed. However, since these materials are acrylic and plastic, the thickness and quality of those materials cause attenuation and scatter in itself. We developed a paper sheet phantom sealed with a pouch laminator, which can be a true radioactive source in air. In this study, the paper sheet phantom was compared to the acrylic liver phantom, with the thickness of 2 cm, which is commercially available. The results showed that although some scatter counts were contained within the image of the acrylic liver phantom, there were few scattered photons in the paper sheet phantom image. Furthermore, this laminated paper sheet phantom made handling of the source and its waste easier. If the paper sheet phantom will be designed more sophisticatedly, it becomes a useful tool for planar imaging experiments. (author)

The AdS5xS5 superstring worldsheet S matrix and crossing symmetry

International Nuclear Information System (INIS)

Janik, Romuald A.

2006-01-01

An S matrix satisfying the Yang-Baxter equation with symmetries relevant to the AdS 5 xS 5 superstring recently has been determined up to an unknown scalar factor. Such scalar factors are typically fixed using crossing relations; however, due to the lack of conventional relativistic invariance, in this case its determination remained an open problem. In this paper we propose an algebraic way to implement crossing relations for the AdS 5 xS 5 superstring worldsheet S matrix. We base our construction on a Hopf-algebraic formulation of crossing in terms of the antipode and introduce generalized rapidities living on the universal cover of the parameter space which is constructed through an auxillary, coupling-constant dependent, elliptic curve. We determine the crossing transformation and write functional equations for the scalar factor of the S matrix in the generalized rapidity plane

X-radiography using photographic papers

Nitiyaporn, W.

1986-01-01

The objective of this research is to study the possibility of using photographic paper, available on the market, for x-ray radiography instead of x-ray film which is more expensive and more complicate to develop. This research concerned about (1) the method and the limitation of x-ray radiography by using 3 types of photographic paper, namely, F2, F3 and F4 distributed by the Kodak Company, as the screen with 3 different kinds of intensifying screens produced by the Phillips Company, Toshiba Company and Picker Company to increase photographic efficiency; (2) correction factor between these 3 types of photographic paper and intensifying screens; (3) the most suitable combination of photographic paper and intensifying screens used; (4) the result of using photographic paper and x-ray film in x-ray radiography regarding quality, cost and film developing. From the research, it was found that (1) the combination of intensifying screen from Picker Company and Kodak photographic paper No. F4 coating with silver bromide with a little mixture of silver iodide resulted in higher sensitivity and more contrast than other combination; (2) photographic papers had more limitation than x-ray film in the sense that it could be used with the iron test piece no thicker than 3 cm.with the x-ray energy of 220 k Vp; (3) photographic papers would give almost the same degree of contrast and sensitivity as x-ray film when used with thin test specimens. For instance the smallest wire No.12 of DIN 62 FE could be seen in the photographic paper at 220 k Vp while it could be seen in the x-ray film at 200 k Vp while it could be seen in the x-ray film at 200 k Vp. The exposure of photographic paper would be in vicinity of x-ray film when it was used with thin test specimens. Photographic paper would produce sharpness definition, density and contrast picture and also details of the picture closely to what given by x-ray film. It is concluded that if the test specimens are thin, photographic papers

Radiation application for paper preservation: gamma irradiation at Eucalyptus pulp sheets

International Nuclear Information System (INIS)

Borrely, Sueli Ivone; Barbosa, Patricia S.M.; D'Almeida, Maria Luiza O.

2009-01-01

Ionizing radiation has been proposed in order to protect information and books that may be lost due to fungi and or insects infestation. In general restaurators are very worried about the maintenance of original properties of items to be treated. The selected technology must consider two points: type of biological contamination and contamination control. Fungi is one of the principal organism which grows well on papers. Once this infestation is installed on the paper it will signify spots, resistance loses and deterioration. The organisms feces introduces enzymes, organic acids and pigments to the contaminated material. Ionizing radiation from gamma sources were applied at laboratory sheets manufactured with commercial cellulose pulp. The subject of this present paper was to investigate the ideal radiation dose that is safe for keeping the paper quality. Laboratory sheets (75 g/m 2 ) were prepared in a TAPPI sheet former. Bleached sulphate Eucalyptus pulp, refined in laboratory PFI mill to 31 deg SR, was the raw material. The formed sheets were irradiated at IPEN's 60 Co Gammacell with 3 kGy up to 25 kGy. No significant changes were detected in paper samples irradiated up to 9 kGy. This is the radiation dose to be suggested. During irradiation the applied dose rate was 0.817 Gy/s. (author)

1982-01-01

The effect of irradiation on enzymatic hydrolysis of waste papers was studied. The sugar yield increased with increasing irradiation dose. In irradiation of deligninized paper, no acceleration of enzymatic hydrolysis was observed. Degradation of cellulose molecules in paper by irradiation was examined by measurements of degree of polymerization and of potential reducing sugar. It was found in enzymatic hydrolysis that oligosaccharides such as celobiose were produced by irradiation. In irradiation of waste papers in catbon dioxide atmosphere, the glucose yield during enzymatic hydrolysis increased with increasing carbon dioxide gas pressure. (author)

Waste paper as a biomass feedstock

International Nuclear Information System (INIS)

1993-09-01

A study was undertaken to evaluate the availability and suitability of waste paper for conversion to biofuel in Canada and to examine the environmental impacts of waste paper processing. The total quantity of waste paper available in 1991 for each province and territory was determined and broken down into seven paper types. The total quantity across Canada was estimated at between 5.7 million and 7.6 million tonnes, of which old corrugated containers made up 23-26%. The variation in prices by waste paper type was also examined on a regional basis and a detailed analysis was made of the recent history of prices for several paper types. Waste paper prices have generally decreased, but since mid-1992, prices for certain types such as writing paper, computer output paper, and newsprint have increased steadily, partly due to increasing demand for recycled content in new paper. Utilization and disposal practices by region for waste paper generated in 1991, including recycling, conversion, and landfilling, were studied. National quantities of waste paper recycled, landfilled, and unavailable for recycling are estimated. The feasibility of using each type of waste paper as feedstock for each of three conversion processes (pyrolysis, incineration, fermentation) was examined. Scenarios were then developed for evaluating environmental impacts of each conversion technology. The environmental impacts of recycling, conversion, and landfilling practices are discussed qualitatively. 92 refs., 16 figs., 53 tabs

Full Text Available This paper deals with the printability of synthetic papers by the electrophotography technique. Prints of cmyk colour fields from 20% to 100% raster tone values were printed on three types of synthetic papers (one film synthetic paper and two fiber synthetic papers. The investigation of the appearance included densitometric measurement of the cmyk prints. The results have shown differences in the optical density and optical tone value between cmyk prints made on various synthetic papers. The highest optical density and the increase of the optical tone value were observed on the film synthetic paper, where cmyk prints were more saturated. The highest abrasion resistance of cmyk prints was obtained from the fibre synthetic paper.

Experimental and numerical studies on liquid wicking into filter papers for paper-based diagnostics

Liu, Zhi; Hu, Jie; Zhao, Yimeng; Qu, Zhiguo; Xu, Feng

2015-01-01

Paper-based diagnostics have shown promising potential applications in human disease surveillance and food safety analysis at the point-of-care (POC). The liquid wicking behavior in diagnostic fibrous paper plays an important role in development of paper-based diagnostics. In the current study, we performed experimental and numerical research on the liquid wicking height and mass with three width strips into filter paper. The effective porosity could be conveniently measured in the light of the linear correlation between wicking height and mass by the experimental system. A modified model with considering evaporation effect was proposed to predict wicking height and mass. The predicted wicking height and mass using the evaporation model was much closer to the experimental data compared with the model without evaporation. The wicking speed initially decreased significantly and then maintained at a constant value at lower level. The evaporation effect tends to reduce the wicking flow speed. More wicking mass could be obtained at larger strip width but the corresponding reagent loss became significant. The proposed model with evaporation paved a way to understanding the fundamental of fluid flow in diagnostic paper and was essential to provide meaningful and useful reference for the research and development of paper-based diagnostics devices. - Highlights: • A model with considering evaporation was proposed to predict wicking height and mass. • Flow characteristics of filter paper were experimentally and theoretically studied. • Effective porosity could be conveniently measured by the experimental platform. • The evaporation effect tended to reduce the wicking flow speed

The City of Brampton's Transportation and Transit Master Plan includes a workable plan to promote walking and cycling facilities in the area. This paper reviewed existing policies, programs and practices in the City of Brampton that pertain to cycling and walking. Walking and cycling issues and trends were also reviewed with reference to the principles that improve the pedestrian and cycling environment, such as safety, security, convenience, continuity, comfort, coherence and attractiveness. The recreation, health and fitness benefits of walking and cycling were also outlined along with transportation, environmental, and economic benefits. The official plan for the city was included with reference to walking and cycling sections in the city. It was noted that effective pathways should be customer driven and respond to the needs of residents. They should also accommodate all uses, including walking, jogging, cycling and in-line skating. Experience of other jurisdictions in Ontario in providing walking and cycling facilities were also reviewed. It was noted that walking and cycling are significant elements of an intermodal transportation system and have a strong bearing on a city's vision for urban street design. 11 refs., 2 tabs., 3 figs.

The ocean modelling is a rapidly evolving science and a large number of results have been published. Several categories of papers are of particular interest for this review: the papers published by the international atomic institutions, such as the NEA (for the CRESP or Subseabed Programs), the IAEA (for example the Safety Series, the Technical Report Series or the TECDOC), and the ICRP, and the papers concerned by more fundamental research, which are published in specific scientific literature. This paper aims to list some of the most relevant publications for the CRESP purposes. It means by no way to be exhaustive, but informative on the incontestable progress recently achieved in that field. One should note that some of these papers are so recent that their final version has not yet been published

Dangerous abbreviations on the Institute for Safe Medication Practices Canada's "Do Not Use" list have resulted in medication errors leading to harm. Data comparing rates of use of dangerous abbreviations in paper and electronic medication orders are limited. To compare rates of use of dangerous abbreviations from the "Do Not Use" list, in paper and electronic medication orders. Secondary objectives include determining the proportion of patients at risk for medication errors due to dangerous abbreviations and the most commonly used dangerous abbreviations. One-day cross-sectional audits of medication orders were conducted at a 6-site hospital network in Toronto, Canada, between December 2013 and January 2014. Proportions of paper and electronic medication orders containing dangerous abbreviation(s) were compared using a χ 2 test. The proportion of patients with at least 1 medication order containing dangerous abbreviation(s) and the top 5 dangerous abbreviations used were described. Overall, 255 patient charts were reviewed. The proportions of paper and electronic medication orders containing dangerous abbreviation(s) were 172/714 (24.1%) and 9/2207 (0.4%), respectively ( P < 0.001). Almost one-third of patients had medication order(s) containing dangerous abbreviation(s). The proportions of patients with at least 1 medication order during the audit period containing dangerous abbreviation(s) for patients with paper only, electronic only, or a hybrid of paper and electronic medication orders were 50.5%, 5%, and 47.2%, respectively. Those most commonly used were "D/C", drug name abbreviations, "OD," "cc," and "U." Electronic medication orders have significantly lower rates of dangerous abbreviation use compared to paper medication orders.

Introduction to four papers on Curt Richter and analysis of his scientific practice.

Science.gov (United States)

Smith, Gerard P

2007-09-01

Curt Richter was one of the founders of our field. He did outstanding research for over 60 years. Richter did fundamental work in appetite for food and minerals in the 1930s and discovered the homeostatic functions of ingestive behavior. This paper introduces four papers on specific topics of his work by contemporaneous experts. Each of the papers reviews Richter's experiments and then shows how the problem developed since he left it. The papers demonstrate that providing the historical basis for contemporary science is not only instructive, it is also heuristic for the science waiting to be done. In addition to introducing the four papers, I analyze the scientific ideas, values, and men that influenced Richter's scientific practice. I conclude that Claude Bernard, Walter Cannon, Francois Magendie, and Maurice Arthus were important for Richter's scientific ideas and values, but it was the joy of research that explains his experimental success for over 60 years.

Power sale. An activity of increasing importance in S.N Nuclearelectrica S.A

International Nuclear Information System (INIS)

Metes, Mircea

2006-01-01

The paper discusses the main characteristics of the power market in Romania. S. N. Nuclearelectrica S.A., the operator of Cernavoda nuclear power plant, is a new power supplier on this market. The price formation of the power sold by S. N. Nuclearelectrica S. A., its participation to the power market as well as the structure of the production costs at Cernavoda NPP are presented. The paper has the following contents: The electricity companies; - From service supplier to wholesale dealer; - Regulated contracts vs. free market; - The shock from 1 July 2005; - The last but not the final challenge. At the above noted date two events with an direct impact upon the power sale by Nuclearelectrica S.A. in Romania took place: 1.The new Trade Code of the power gross market became operative; 2. The opening degree of the free market raised steeply from 55% to over 83% of the energy demand, all the industrial consumers having the right of having the statute of 'eligible consumer'. The conclusion of the paper is that the reduced production cost in the nuclear unit as compared with those of classical stations, as well as a correct planning of the production are favorable premises to a successful transaction and sale of power produced at Cernavoda NPP

Full Text Available Based on the debate on children’s ability to produce argumentative discourse in different edu­cational settings, this paper provides further support for the fact that small children are able to support their opinions with arguments. In particular, the paper makes a case in point on children’s appeal to definitional loci, when supporting their standpoints. The analysis of their reasoning’s implicit components shows how children apply different definitional arguments.

Salt Repository Project waste emplacement mode decision paper: Revison 1

International Nuclear Information System (INIS)

1987-08-01

This paper provides a recommendation as to the mode of waste emplacement to be used as the current basis for site characterization activity for the Deaf Smith County, Texas, high level nuclear waste repository site. It also presents a plan for implementing the recommendation so as to provide a high level of confidence in the project's success. Since evaluations of high-level waste disposal in geologic repositories began in the 1950s, most studies emplacement in salt formations employed the vertical orientation for emplacing waste packages in boreholes in the floor of the underground facility. This orientation was used in trials at Project Salt Vault in the 1960s. The Waste Isolation Pilot Plant (WIPP) has recently settled on a combination of vertical and horizontal modes for various waste types. This paper analyzes the information available and develops a project position upon which to base current site characterization activities. The position recommended is that the SRP should continue to use the vertical waste emplacement mode as the reference design and to carry the horizontal mode as a ''passive'' alternative. This position was developed based upon the conclusions of a decision analysis, risk assessment, and cost/schedule impact assessment. 52 refs., 6 figs., 1 tab

The analytical performance for paper spray (PS) using a new insert sample approach based on paper with paraffin barriers (PS-PB) is presented. The paraffin barrier is made using a simple, fast and cheap method based on the stamping of paraffin onto a paper surface. Typical operation conditions of paper spray such as the solvent volume applied on the paper surface, and the paper substrate type are evaluated. A paper substrate with paraffin barriers shows better performance on analysis of a range of typical analytes when compared to the conventional PS-MS using normal paper (PS-NP) and PS-MS using paper with two rounded corners (PS-RC). PS-PB was applied to detect sugars and their inhibitors in sugarcane bagasse liquors from a second generation ethanol process. Moreover, the PS-PB proved to be excellent, showing results for the quantification of glucose in hydrolysis liquors with excellent linearity (R(2) = 0.99), limits of detection (2.77 mmol L(-1)) and quantification (9.27 mmol L(-1)). The results are better than for PS-NP and PS-RC. The PS-PB was also excellent in performance when compared with the HPLC-UV method for glucose quantification on hydrolysis of liquor samples.

High-level radioactive waste in Canada. Background paper

International Nuclear Information System (INIS)

Fawcett, R.

1993-11-01

The disposal of radioactive waste is one of the most challenging environmental problems facing Canada today. Since the Second World War, when Canadian scientists first started to investigate nuclear reactions, there has been a steady accumulation of such waste. Research reactors built in the early postwar years produced small amounts of radioactive material but the volume grew steadily as the nuclear power reactors constructed during the 1960s and 1970s began to spawn used fuel bundles. Although this radioactive refuse has been safely stored for the short term, no permanent disposal system has yet been fully developed and implemented. Canada is not alone in this regard. A large number of countries use nuclear power reactors but none has yet put in place a method for the long-term disposal of the radioactive waste. Scientists and engineers throughout the world are investigating different possibilities; however, enormous difficulties remain. In Canada, used fuel bundles from nuclear reactors are defined as high-level waste; all other waste created at different stages in the nuclear fuel cycle is classified as low-level. Although disposal of low-level waste is an important issue, it is a more tractable problem than the disposal of high-level waste, on which this paper will concentrate. The paper discusses the nuclear fuel waste management program in Canada, where a long-term disposal plan has been under development by scientists and engineers over the past 15 years, but will not be completed for some time. Also discussed are responses to the program by parliamentary committees and aboriginal and environmental groups, and the work in the area being conducted in other countries. (author). 1 tab

The development of the next generation of multi-domain unmanned semi and fully autonomous C4ISR systems involves a multitude of security concerns and interoperability challenges. Conceptual solutions to capability shortfalls and gaps can be identified through Concept Development and Experimentation (CD and E) cycles. Modelling and Simulation (M and S) is a key tool in supporting unmanned autonomous systems (UAxS) CD and E activities and addressing associated security challenges. This paper serves to illustrate the application of M and S to UAxS development and highlight initiatives made by the North Atlantic Treaty Organization (NATO) M and S Centre of Excellence (CoE) to facilitate interoperability. The NATO M and S CoE collaborates with other NATO and Nations bodies in order to develop UAxS projects such as the Allied Command for Transformation Counter Unmanned Autonomous Systems (CUAxS) project or the work of Science and Technology Organization (STO) panels. Some initiatives, such as Simulated Interactive Robotics Initiative (SIRI) made the baseline for further developments and to study emerging technologies in M and S and robotics fields. Artificial Intelligence algorithm modelling, Robot Operating Systems (ROS), network operations, cyber security, interoperable languages and related data models are some of the main aspects considered in this paper. In particular, the implementation of interoperable languages like C-BML and NIEM MilOps are discussed in relation to a Command and Control - Simulation Interoperability (C2SIM) paradigm. All these technologies are used to build a conceptual architecture to support UAxS CD and E.In addition, other projects that the NATO M and S CoE is involved in, such as the NATO Urbanization Project could provide credible future operational environments and benefit UAxS project development, as dual application of UAxS technology in large urbanized areas.In conclusion, this paper contains a detailed overview regarding how applying

The article examines the idea of Europe conceived by Stefan Zweig and Hermann Ullmann in the similarly titled books about Brazil written in the late 1930s and early 1940s. In the political context between the great wars marked by the rise of Nazism, the question is posed regarding to what extent Europe continues to serve as a model of civilization and what the critical dimension is that is expressed in concepts reversing the roles of Europe and Brazil. One detects a partial rupture with dichotomous and hierarchical viewpoints about the relationship between the Old World and the New World, and new forms of relationship between these regions within the worldwide context are suggested.

Toward a formalization of the process to select IMIA Yearbook best papers.

Lamy, J-B; Séroussi, B; Griffon, N; Kerdelhué, G; Jaulent, M-C; Bouaud, J

2015-01-01

Each year, the International Medical Informatics Association Yearbook recognizes significant scientific papers, labelled as "best papers", published the previous year in the subfields of biomedical informatics that correspond to the different section topics of the journal. For each section, about fifteen pre-selected "candidate" best papers are externally peer-reviewed to select the actual best papers. Although based on the available literature, little is known about the pre-selection process. To move toward an explicit formalization of the candidate best papers selection process to reduce variability in the literature search across sections and over years. A methodological framework is proposed to build for each section topic specific queries tailored to PubMed and Web of Science citation databases. The two sets of returned papers are merged and reviewed by two independent section editors and citations are tagged as "discarded", "pending", and "kept". A protocolized consolidation step is then jointly conducted to resolve conflicts. A bibliographic software tool, BibReview, was developed to support the whole process. The proposed search strategy was fully applied to the Decision Support section of the 2013 edition of the Yearbook. For this section, 1124 references were returned (689 PubMed-specific, 254 WoS-specific, 181 common to both databases) among which the 15 candidate best papers were selected. The search strategy for determining candidate best papers for an IMIA Yearbook's section is now explicitly specified and allows for reproducibility. However, some aspects of the whole process remain reviewer-dependent, mostly because there is no characterization of a "best paper".

The application of H2 in S.I. engines. Paper no. IGEC-1-065

International Nuclear Information System (INIS)

Li, H.; Neill, W.S.; Karim, G.A.

2005-01-01

Hydrogen has long been recognized as a fuel having some unique and highly desirable combustion properties, such as a wide flammable mixture range, low ignition energy, very fast flame propagation rates and clean combustion products especially without greenhouse gases. These features made H 2 an excellent fuel for both traditional and emerging innovative power devices such as spark ignition engines and fuel cells. The application of H 2 makes it possible for these devices to potentially meet the ever increasingly stringent environmental controls of exhaust emissions, including the possible elimination of green house gas emissions. This paper contributes to the experimental examination of H 2 applications in spark ignition engines. The detailed engine performance including the onset of knock, lean operational limits and exhaust emissions is to be presented. Comparison with the corresponding performances of other common gases fuels such as natural gas is made. The optimization of spark timing for efficiency and for the avoidance of knock while maintaining high thermal efficiency is also to be discussed. (author)

2015-02-01

Full Text Available This paper explores some key insights and lessons from Royal Professor Ungku Abdul Aziz bin Ungku Abdul Hamid (born 1922 – present, a celebrated academician in Malaysia, on development. Drawing from Ungku Aziz’s main articles, papers and books, the paper attempts to make wider connections with regards to Ungku Aziz’s endeavour in development. This paper sheds new light and draw lessons on the meaning of ‘development’ and its implications to the Muslim community. The main finding indicated that Ungku Aziz had creatively interpreted ‘development’ geared towards the needs of the local community away from the Western-centric notion and ideals. It is not mere imitation of modern Western conception of ‘development’, nor is it a wholesale rejection of it, but it is a creative interpretation that takes into consideration the economic reality as well as the spiritual, social and cultural well being of the local community. This study also revealed that the Ungku Aziz’s conception of ‘development’ has significant relationship with the right theological and civilizational interpretation of the religion of Islam. This paper contends that Ungku Aziz’s conception of ‘development’ should be expanded further using the right religious and civilizational framework as part of the continuous civilizing process of the Muslim world.

Improving the analytical performance and versatility of paper spray mass spectrometry via paper microfluidics.

Science.gov (United States)

Murray, Ian; Walker, Glenn; Bereman, Michael S

2016-06-20

Two paper-based microfluidic techniques, photolithography and wax patterning, were investigated for their potential to improve upon the sensitivity, reproducibility, and versatility of paper spray mass spectrometry. The main limitation of photolithography was the significant signal (approximately three orders of magnitude) above background which was attributed to the chemicals used in the photoresist process. Hydrophobic barriers created via wax patterning were discovered to have approximately 2 orders of magnitude less background signal compared to analogous barriers created using photolithography. A minimum printed wax barrier thickness of approximately 0.3 mm was necessary to consistently retain commonly used paper spray solvents (1 : 1 water : acetonitrile/methanol) and avoid leakage. Constricting capillary flow via wax-printed channels yielded both a significant increase in signal and detection time for detection of model analytes. This signal increase, which was attributed to restricting the radial flow of analyte/solvent on paper (i.e., a concentrating effect), afforded a significant increase in sensitivity (p ≪ 0.05) for the detection of pesticides spiked into residential tap water using a five-point calibration curve. Finally, unique mixing designs using wax patterning can be envisioned to perform on-paper analyte derivatization.

Cao, Liujun; Tang, Gang; Mei, Jun; Liu, Hao

2017-08-01

In order to boost the energy density of supercapacitors, the strategy of using advanced pseudo-capacitive electrode and asymmetric device architecture is feasible and effective. Herein, we report a significant advance in the design and synthesis of a new hierarchically nanostructures with a series of controllable Ni/Co molar ratios of NixCo3-xS4 (i.e., NiCo2S4 and Ni2CoS4) nanosheets coatings have in situ grown on NiCo2O4 nanowires arrays on a flexible carbon fiber paper (CFP). Remarkably, the hybrid Ni2CoS4@NiCo2O4 composite electrode delivers the highest discharge gravimetric capacitance of 1501 F g-1, and areal capacitance of 1.86 F cm-2 at 1 mA cm-2. Furthermore, coupled with nitrogen-doped carbon xerogels anode, we have fabricated a 1.6 V asymmetric supercapacitor (Ni2CoS4@NiCo2O4//nitrogen-doped carbon xerogels), such device delivers a maximum energy and power densities of 32.2 Wh kg-1 and 2.5 kW kg-1 in 1.0 M KOH electrolyte, respectively, and an excellent cycling stability (∼87.6% retention after 10,000 cycles).

Comparing the market for nuclear power in Alberta and Saskatchewan - draft paper

Energy Technology Data Exchange (ETDEWEB)

Bratt, D. [Dept. of Policy Studies, Mount Royal College, Calgary, Alberta (Canada)], E-mail: dbratt@mtroyal.ca

This paper compares the markets for nuclear power in Alberta and Saskatchewan. This is done by comparing the two provincial panels that were released in Spring 2009 (Saskatchewan's Uranium Development Partnership and Alberta's Nuclear Power Expert Panel). Each panels terms of reference, membership, process, analysis, recommendations, and public consultation process are examined. Other variables for comparison include the history of its involvement in the nuclear sector, the political support, and public support. It concludes by arguing that Saskatchewan is a better market for nuclear power and that it is likely that a nuclear reactor will be built in Saskatchewan, but that surplus electricity will also be exported to Alberta. The possibility of building new nuclear power plants in both Alberta and Saskatchewan is increasing. This would not only increase the size of the Canadian nuclear industry it would also geographically expand it. Many non-Westerners see the prairies as a homogenous whole, but there are critical differences between Alberta and Saskatchewan. Analyzing these political and market differences would provide a good predicative power over the ultimate success of the nuclear power initiatives. This paper conducts a detailed comparison of the Alberta Government's Nuclear Power Expert Panel (NPEP) report and the Saskatchewan Government's Uranium Development Partnership (UDP) report. Topics for comparison include the terms of reference, membership, process, analysis, recommendations, and public consultation process. It also examines the history of each province's involvement in the nuclear industry; the level of political support including the positions of the provincial political parties; and the level of public support and knowledge.

Science.gov (United States)

Nie, Jinfang; Liang, Yuanzhi; Zhang, Yun; Le, Shangwang; Li, Dunnan; Zhang, Songbai

2013-01-21

In this paper, we report a simple, low-cost method for rapid, highly reproductive fabrication of paper-based microfluidics by using a commercially available, minitype CO(2) laser cutting/engraving machine. This method involves only one operation of cutting a piece of paper by laser according to a predesigned pattern. The hollow microstructures formed in the paper are used as the 'hydrophobic barriers' to define the hydrophilic flowing paths. A typical paper device on a 4 cm × 4 cm piece of paper can be fabricated within ∼7-20 s; it is ready for use once the cutting process is finished. The main fabrication parameters such as the applied current and cutting rate of the laser were optimized. The fabrication resolution and multiplexed analytical capability of the hollow microstructure-patterned paper were also characterized.

Lumpy investment, sectoral propagation, and business cycles (Invited Paper)

Science.gov (United States)

Nirei, Makoto

2005-05-01

This paper proposes a model of endogenous fluctuations in investment. A monopolistic producer has an incentive to invest when the aggregate demand is high. The investment at the firm level is also known to exhibit a threshold behavior called an (S,s) policy. These two facts lead us to consider that the fluctuation in aggregate investment is generated by the global coupling of the non-linear oscillators. From this perspective, we characterize the probability distribution of the investment clustering in a partial equilibrium of product markets, and show that its variance can be large enough to match the observed investment fluctuations. We then implement this mechanism in a dynamic general equilibrium model to explore an investment-driven business cycle. By calibrating the model with the SIC 4-digit level industry data, we numerically show that the model replicates the basic structure of the business cycles.

Biomass based optimal cogeneration system for paper industry

Energy Technology Data Exchange (ETDEWEB)

Ashok, S.; Jayaraj, S. [National Inst. of Technology, Calicut (India)

2008-07-01

A mathematical model of a biomass supported steam turbine cogeneration system was presented. The multi-time interval non-linear model used genetic algorithms to determine optimal operating costs. The cogeneration system consisted of steam boilers; steam headers at different pressure levels; steam turbines operating at different capacities; and other auxiliary devices. System components were modelled separately to determine constraints and costs. Total costs were obtained by summing up costs corresponding to all equipment. Cost functions were fuel cost; grid electricity cost; grid electricity export revenues; start-up costs; and shut-down costs. The non-linear optimization model was formulated by considering equal intervals of 1-hour intervals. A case study of a typical paper industry plant system was considered using coal, black liquor, and groundnut shells. Results of the study showed that the use of groundnut shells as a fuel resulted in a savings of 11.1 per cent of the total monthly operating costs while delivering 48.6 MWh daily to the electricity grid after meeting the plant's total energy requirements. It was concluded that the model can be used to optimize cogeneration systems in paper plants. 14 refs., 3 tabs., 3 figs.

Strategies and Objectives for Addressing Climate Change; IV. Policies and Actions to Decelerate Climate Change; V. Policies and Actions to Adapt to Climate Change; VI. Enhancing Public Awareness in Addressing Climate Change; VII. Enhancing International Cooperation on Climate Change; VIII. Institution and Mechanism Building for Coping with Climate Change; and Conclusion. Measures for control of greenhouse gas emissions include optimizing the energy consumption structure through developing renewable energy, boosting nuclear power plant construction and speeding up the development and utilization of coal-bed gas. The target by 2010 is to raise the proportion of renewable energy (including large-scale hydropower) in the primary energy supply by up to 10 percent, and the extraction of coal-bed gas up to 10 billion cu m. China will push forward the use of clean coal and develop efficient and clean power generating technology, such as large-scale combined cycle units and poly-generation, and promote technology for carbon dioxide sequestration. China has decided to place the emphasis of its research on technologies which include technologies for the clean and efficient exploitation and utilization of coal, petroleum and natural gas; technologies for manufacturing advanced equipment for coal- and nuclear-generated power; technologies for capturing, utilizing and storing carbon dioxide; and technologies that control greenhouse gas emissions in agriculture and how land is used.

On Dreams and Motivation: Comparison of Freud’s and Hobson’s Views

Science.gov (United States)

Boag, Simon

2017-01-01

The merits of Freudian dream theory continue to be debated and both supporters and critics appeal to empirical evidence to support their respective positions. What receives much less attention is the theoretical coherency of either Freudian dream theory or alternative perspectives. This paper examines Freudian dream theory and J. Allan Hobson’s alternative position by addressing the role of motivation in dreams. This paper first discusses motivation in Freudian theory and its relation to dreams and disguise-censorship. The role of motivation in Hobson’s theory is then considered. Hobson’s claim that dream plot and content selection is random and based on design error and functional imbalance is then discussed in relation to the protoconsciousness theory proposal that dreams serve an adaptive function. While there are apparent inconsistencies in Hobson’s position, his appeal to emotions and instincts provides a preliminary platform for understanding the role of motivation in dreams that is consonant with the Freudian position.

Pereira, L; Gaspar, D; Fortunato, E; Martins, R; Guerin, D; Delattre, A

2014-01-01

Paper electronics is a topic of great interest due the possibility of having low-cost, disposable and recyclable electronic devices. The final goal is to make paper itself an active part of such devices. In this work we present new approaches in the selection of tailored paper, aiming to use it simultaneously as substrate and dielectric in oxide based paper field effect transistors (FETs). From the work performed, it was observed that the gate leakage current in paper FETs can be reduced using a dense microfiber/nanofiber cellulose paper as the dielectric. Also, the stability of these devices against changes in relative humidity is improved. On other hand, if the pH of the microfiber/nanofiber cellulose pulp is modified by the addition of HCl, the saturation mobility of the devices increases up to 16 cm 2  V −1  s −1 , with an I ON /I OFF ratio close to 10 5 .

The status of citations can reflect the impact of a paper and its contribution to surgical practice. The aim of our study was to identify and review the 100 most-cited papers in general thoracic surgery. Relevant papers on general thoracic surgery were searched through Thomson Reuters Web of Science in the last week of November 2017. Results were returned in descending order of total citations. Their titles and abstracts were reviewed to identify whether they met our inclusion criteria by two thoracic surgeons independently. Characteristics of the first 100 papers, including title, journal name, country, first author, year of publication, total citations, citations in latest 5 years and average citation per year (ACY) were extracted and analyzed. Of the 100 papers, the mean number of citations was 322 with a range from 184 to 921. 19 journals published the papers from 1956 to 2012. Annals of Surgery had the largest number (29), followed by Journal of Thoracic and Cardiovascular Surgery (22) and Annals of Thoracic Surgery (21). The majority of the papers were published in 2000s (48) and originated from United States of America (62). There were 65 retrospective studies, 13 RCTs and 11 prospective studies. Orringer MB and Grillo HC contributed 4 first-author articles respectively. There were 53 papers on esophagus, 36 on lung, 6 on pleura and 5 on trachea. Our study identified the most-cited papers in the past several decades and offered insights into the development and advances of general thoracic surgery. It can help us understand the evidential basis of clinical decision-making today in the area. Copyright © 2018. Published by Elsevier Ltd.

International Oil Price’s Impacts on Carbon Emission in China’s Transportation Industry

Directory of Open Access Journals (Sweden)

Guoxing Zhang

2014-09-01

Full Text Available Purpose: This paper analyses the impact mechanism of international oil price on the industrial carbon emission, and uses the partial least squares regression model to study international oil price’s impact on carbon emissions in China’s transportation industry.Design/methodology/approach: This paper chooses five independent variables of GDP, international oil price, private car population, passenger and freight transportation volume as impact factors to investigate industrial carbon emissions, the paper also analyses the impact mechanism of international oil price on the industrial carbon emission, and finally the paper uses the partial least squares regression model to study international oil price’s impact on carbon emissions in China’s transportation industry. With the independent variables’ historical data from 1994 to 2009 as a sample, the fitting of the industry carbon emissions is satisfying. And based on the data of 2011, the paper maintains the private car owning, passenger and freight transportation volume to study international oil prices’ impact on the industry carbon emissions at different levels of GDP.Findings: The results show that: with the same GDP growth, the industry carbon emissions increase with the rise in international oil prices, and vice versa, the industry carbon emissions decrease; and lastly when GDP increases to a certain extent, in both cases of international oil prices’ rise or fall, the industry carbon emissions will go up, and the industry carbon emissions increase even faster while the energy prices are rising.Practical implications: Limit the growth in private-vehicle ownership, change China's transport sector within the next short-term in the structure of energy consumption and put forward China's new energy, alternative energy sources and renewable energy application so as to weaken the dependence on international oil, and indirectly slowdown China's GDP growth rate, which are all possible

Migration of fluorochemical paper additives from food-contact paper into foods and food simulants.

Science.gov (United States)

Begley, T H; Hsu, W; Noonan, G; Diachenko, G

2008-03-01

Fluorochemical-treated paper was tested to determine the amount of migration that occurs into foods and food-simulating liquids and the characteristics of the migration. Migration characteristics of fluorochemicals from paper were examined in Miglyol, butter, water, vinegar, water-ethanol solutions, emulsions and pure oil containing small amounts of emulsifiers. Additionally, microwave popcorn and chocolate spread were used to investigate migration. Results indicate that fluorochemicals paper additives do migrate to food during actual package use. For example, we found that microwave popcorn contained 3.2 fluorochemical mg kg(-1) popcorn after popping and butter contained 0.1 mg kg(-1) after 40 days at 4 degrees C. Tests also indicate that common food-simulating liquids for migration testing and package material evaluation might not provide an accurate indication of the amount of fluorochemical that actually migrates to food. Tests show that oil containing small amounts of an emulsifier can significantly enhance migration of a fluorochemical from paper.

Under a linear mixed-frequency data-generating process, MiDaS regressions provide a parsimoniously parameterized nonlinear alternative when the linear forecasting model is over-parameterized and may be infeasible. In spite of potential correlation of the error term both serially and with the regressors, I find that nonlinear least squares consistent...

The investigation of paper mill industry wastewater treatment and activated sludge properties in a submerged membrane bioreactor.

Erkan, Hanife Sari; Engin, Guleda Onkal

2017-10-01

The paper mill industry produces high amounts of wastewater and, for this reason, stringent discharge limits are applied for sustainable reclamation and reuse of paper mill industry wastewater in many countries. Submerged membrane bioreactor (sMBR) systems can create new opportunities to eliminate dissolved substances present in paper mill wastewater including. In this study, a sMBR was operated for the treatment of paper mill industry wastewater at 35 h of hydraulic retention time (HRT) and 40 d of sludge retention time (SRT). The chemical oxygen demand (COD), NH 3 -N and total phosphorus (TP) removal efficiencies were found to be 98%, 92.99% and 96.36%. The results demonstrated that sMBR was a suitable treatment for the removal of organic matter and nutrients for treating paper mill wastewater except for the problem of calcium accumulation. During the experimental studies, it was noted that the inorganic fraction of the sludge increased as a result of calcium accumulation in the reactor and increased membrane fouling was observed on the membrane surface due to the calcification problem encountered. The properties of the sludge, such as extracellular polymeric substances (EPS) and soluble microbial products (SMP), relative hydrophobicity, zeta potential and floc size distribution were also monitored. According to the obtained results, the total EPS was found to be 43.93 mg/gMLSS and the average total SMP rejection by the membrane was determined as 66.2%.

WASP (Write a Scientific Paper) using Excel - 1: Data entry and validation.

Grech, Victor

2018-02-01

Data collection for the purposes of analysis, after the planning and execution of a research study, commences with data input and validation. The process of data entry and analysis may appear daunting to the uninitiated, but as pointed out in the 1970s in a series of papers by British Medical Journal Deputy Editor TDV Swinscow, modern hardware and software (he was then referring to the availability of hand calculators) permits the performance of statistical testing outside a computer laboratory. In this day and age, modern software, such as the ubiquitous and almost universally familiar Microsoft Excel™ greatly facilitates this process. This first paper comprises the first of a collection of papers which will emulate Swinscow's series, in his own words, "addressed to readers who want to start at the beginning, not to those who are already skilled statisticians." These papers will have less focus on the actual arithmetic, and more emphasis on how to actually implement simple statistics, step by step, using Excel, thereby constituting the equivalent of Swinscow's papers in the personal computer age. Data entry can be facilitated by several underutilised features in Excel. This paper will explain Excel's little-known form function, data validation implementation at input stage, simple coding tips and data cleaning tools. Copyright © 2018 Elsevier B.V.

Quantum Entanglements: Selected Papers

International Nuclear Information System (INIS)

Giannetto, E

2005-01-01

This book is a sort of tribute to Rob Clifton (1964-2002), Associate Professor of Philosophy and Associate Director of the Center for Philosophy of Science at the University of Pittsburgh, philosopher of physics and editor of the journal Studies in the History and Philosophy of Modern Physics, who tragically died of cancer. It contains fourteen papers by Clifton, for the most part written in collaboration with other authors (Jeffrey Bub (2), Sheldon Goldstein, Michael Dickson, Hans Halvorson (6), Adrian Kent (2)), published between 1995 and 2002. The choice of papers made by the editors is very impressive. They concern the foundations of quantum mechanics and quantum field theory. Among the issues discussed are the modal interpretations of quantum mechanics, the problems of hidden variables theories, non-locality, Bell's inequality, the Einstein-Podolsky-Rosen paradox, Lorentz invariance, de-coherence, non-contextuality, complementarity, entanglement and quantum information. A consequence of such investigations is that non-separability is a more complex issue than violation of Bell's inequality. Apart from the perspective one can follow-whether one agrees or not with Clifton-these papers are effective contributions to an understanding of the problems involved in the foundations of quantum mechanics. The most interesting parts, in my opinion, are related to the extension of the discussion of foundational problems to quantum field theory: on the algebraic approach, and on the twin concepts of particle and vacuum. Non-locality appears to be 'worse' in relativistic quantum field theory than in non-relativistic quantum mechanics. All the papers deal with relevant epistemological and even historical aspects of quantum mechanics interpretations, but all the issues are discussed from a technical, logical and mathematical approach. A complete bibliography of Clifton's papers is given at the end of the volume. (book review)

In this paper, we demonstrate the potential benefits that residential buildings can provide for frequency regulation services in the electric power grid. In a hardware-in-the- loop (HIL) implementation, simulated homes along with a physical laboratory home are coordinated via a grid aggregator, and it is shown that their aggregate response has the potential to follow the regulation signal on a timescale of seconds. Connected (communication-enabled), devices in the National Renewable Energy Laboratory's (NREL's) Energy Systems Integration Facility (ESIF) received demand response (DR) requests from a grid aggregator, and the devices responded accordingly to meet the signal while satisfying user comfort bounds and physical hardware limitations. Future research will address the issues of cybersecurity threats, participation rates, and reducing equipment wear-and-tear while providing grid services.

Love’s Labour’s Lost and Much Ado About Nothing: An Early Dipt

OpenAIRE

Chiari, Sophie

2016-01-01

In his Palladis Tamia published in 1598, Francis Meres gave a list of popular plays, already a fairly long one, written by a young playwright aged 34, William Shakespeare. In Meres’s inventory, an intriguing, unknown play called Love’s Labour’s Won is paired with Love’s Labour’s Lost, a mention which has so far remained a complete mystery. This paper aims at reconsidering the hypothesis according to which Much Ado About Nothing might be the comedy designated under the title of Love’s Labour’s...

Editorial highlighting and highly cited papers

Science.gov (United States)

Antonoyiannakis, Manolis

Editorial highlighting-the process whereby journal editors select, at the time of publication, a small subset of papers that are ostensibly of higher quality, importance or interest-is by now a widespread practice among major scientific journal publishers. Depending on the venue, and the extent to which editorial resources are invested in the process, highlighted papers appear as News & Views, Research Highlights, Perspectives, Editors' Choice, IOP Select, Editors' Summary, Spotlight on Optics, Editors' Picks, Viewpoints, Synopses, Editors' Suggestions, etc. Here, we look at the relation between highlighted papers and highly influential papers, which we define at two levels: having received enough citations to be among the (i) top few percent of their journal, and (ii) top 1% of all physics papers. Using multiple linear regression and multilevel regression modeling we examine the parameters associated with highly influential papers. We briefly comment on cause and effect relationships between citedness and highlighting of papers.

Electrochemical Detection in Stacked Paper Networks.

Liu, Xiyuan; Lillehoj, Peter B

2015-08-01

Paper-based electrochemical biosensors are a promising technology that enables rapid, quantitative measurements on an inexpensive platform. However, the control of liquids in paper networks is generally limited to a single sample delivery step. Here, we propose a simple method to automate the loading and delivery of liquid samples to sensing electrodes on paper networks by stacking multiple layers of paper. Using these stacked paper devices (SPDs), we demonstrate a unique strategy to fully immerse planar electrodes by aqueous liquids via capillary flow. Amperometric measurements of xanthine oxidase revealed that electrochemical sensors on four-layer SPDs generated detection signals up to 75% higher compared with those on single-layer paper devices. Furthermore, measurements could be performed with minimal user involvement and completed within 30 min. Due to its simplicity, enhanced automation, and capability for quantitative measurements, stacked paper electrochemical biosensors can be useful tools for point-of-care testing in resource-limited settings. © 2015 Society for Laboratory Automation and Screening.

RF-plasma vapor deposition of siloxane on paper. Part 1: Physical evolution of paper surface

Science.gov (United States)

Sahin, Halil Turgut

2013-01-01

An alternative, new approach to improve the hydrophobicity and barrier properties of paper was evaluated by radio-frequency (RF) plasma octamethylcyclotetrasiloxane (OMCTSO) vapor treatment. The interaction between OMCTSO and paper, causing the increased hydophobicity, is likely through covalent bonding. The deposited thin silicone-like polymeric layer from OMCTSO plasma treatment possessed desirable hydrophobic properties. The SEM micrographs showed uniformly distributed grainy particles with various shapes on the paper surface. Deposition of the silicone polymer-like layer with the plasma treatment affects the distribution of voids in the network structure and increases the barrier against water intake and air. The water absorptivity was reduced by 44% for the OMCTSO plasma treated sheet. The highest resistance to air flow was an approximately 41% lower air permeability than virgin paper.

Full Text Available Paper-based sensors are a new alternative technology for fabricating simple, low-cost, portable and disposable analytical devices for many application areas including clinical diagnosis, food quality control and environmental monitoring. The unique properties of paper which allow passive liquid transport and compatibility with chemicals/biochemicals are the main advantages of using paper as a sensing platform. Depending on the main goal to be achieved in paper-based sensors, the fabrication methods and the analysis techniques can be tuned to fulfill the needs of the end-user. Current paper-based sensors are focused on microfluidic delivery of solution to the detection site whereas more advanced designs involve complex 3-D geometries based on the same microfluidic principles. Although paper-based sensors are very promising, they still suffer from certain limitations such as accuracy and sensitivity. However, it is anticipated that in the future, with advances in fabrication and analytical techniques, that there will be more new and innovative developments in paper-based sensors. These sensors could better meet the current objectives of a viable low-cost and portable device in addition to offering high sensitivity and selectivity, and multiple analyte discrimination. This paper is a review of recent advances in paper-based sensors and covers the following topics: existing fabrication techniques, analytical methods and application areas. Finally, the present challenges and future outlooks are discussed.

A Feminism of Their Own?: Irish Women’s History and Contemporary Irish Women’s Writing

Directory of Open Access Journals (Sweden)

Mary Ryan

2010-03-01

Full Text Available For a long time, Irish women’s lives were strictly confined to the private domain, and women’s issues were largely silenced and hidden from public knowledge. Additionally, both Church and state maintained that women should hold a certain morality, particularly relating to areas of sexuality and reproduction. As a result, until relatively recently, Irish women’s issues remained largely ignored and therefore unremarked upon. This paper will examine two major areas in which Irish women’s lives have traditionally been repressed: women’s sexuality and domestic violence, both issues which were once considered taboo for open discussion. This paper will also discuss how these same issues are being represented in Irish chick lit novels, thus providing a frank and positive voice for these largely female issues and for the everyday experiences of women in Ireland.

The Role of Modal Verbs in Research Papers in the Field of Logistics

Directory of Open Access Journals (Sweden)

Polona Vičič

2016-08-01

Full Text Available Research papers, an essential vehicle for disseminating new knowledge and findings, have long been valued for their linguistic objectivity and impersonality. However, more recent approaches to research paper writing suggest that authors should also take an “argumentative position” (White, 2003 by projecting their stance and encouraging the readers to actively engage in the process of reading and evaluating the text (Hyland, 2005; Scollon, 1994. An important linguistic feature, frequently employed for both objective and subjective presentation of claims, is modality and within it modal verbs, which through their modal meanings express different communicative functions. In recognition of genre- and discipline-specific norms, the present paper will focus on quantitative and qualitative analysis of modal verbs and their meanings and functions in logistics research papers, whereby the ultimate goal is to show what practical implications the study’s results may have for the teaching of English to students of logistics.

Paper Strip-based Fluorometric Determination of Cyanide with an Internal Reference

International Nuclear Information System (INIS)

Lee, Dong-Nam; Hong, Jong-In; Seo, Hyejin; Shin, Ik-Soo

2016-01-01

The rapid, selective, and sensitive determination of cyanide anion (CN"-) using a simple paper strip is highly attractive because cyanide is acutely lethal to living organisms via all routes of administration, including alcohol consumption and inhaling cigarette smoke. Here, a synthetic probe (1) was designed for the selective determination of cyanide. The probe displays rapid and large blue spectral change (Δλ_a_b_s=148 nm, Δλ_e_m= 165 nm) with respect to target recognition. Probe 1 exhibits a strong push-pull electronic effect and comprises a dimethylaminoaryl group as a donor and malononitrile as an acceptor; the π-conjugation system can be destroyed by the Michael-type addition of cyanide at the electrophilic β-positions of the nitrile groups, resulting in the marked emergence of a peak at λ_e_m= 515 nm. The developed probe was successfully applied to a paper test strip because of its noticeable optical changes upon reaction with cyanide. The fabricated dumbbell-shaped paper strip with an internal reference allowed the cyanide detection, which is indispensable for quantitative analysis in point-of-care testing. The paper strip test showed selective response to cyanide, with a linear correlation in the range of 0-25 mM in a simple and cost-effective manner.

Nearly 20 years have passes since the initiation of peaceful uses of atomic energy in Japan. Close to the end of this period, there had occurred the so-called oil crisis, which emphasizes the keen need for nuclear power development. In the meanwhile, voices of the people in Japan are varied concerning the nuclear power, as in siting of the power plants and the n.s. (nuclear ship) Mutsu. The white paper describes the following: safety, environment preservation, nuclear power generation, nuclear fuel cycle, power reactor development and fusion reactor, nuclear-powered ship, radiation utilization, etc. (Mori, K.)

Edward C. Koziara

2000-01-01

Full Text Available This paper traces the naval history of the U.S.S. Olympia and incorporates many photographs to display the current condition of the ship. The paper begins with a brief history of the U.S.S. Olympia and its role in the Spanish-American War, its part as the flagship of the Caribbean, its World War I work and its role in the ill conceived Murmansk intervention and its more successful participation in the Trau pacification of Italians and Yugoslavs; its feature part in the bombing experiments of Billy Mitchell and transporting the Unknown Soldier from France to Washington in a most hazardous journey. It was decommissioned in 1931 and is currently part of the Independence Seaport Museum in Philadelphia. It is docked in the Delaware River about eight blocks from Independence Hall and within easy walking distance of other historical attractions. Similar to the Constitution in Boston the U.S.S. Olympia could be an important part of the Philadelphia waterfront.The ship although in disrepair has a living history crew, which portray the work of the Spanish American seamen. They perform the various drills, play music of the time and prepare food then served. Of particular import is the economics of the Olympia. What is required and what initiatives have been undertaken to restore the Olympia? Rough cost-benefit data is presented to illustrate the advantages and costs of preservation.Finally the paper looks at the regional development of the Philadelphia Center City and the way in which preservation efforts can complement other initiatives to develop the area.

Full Text Available Sandwich panels are new kind of layered composites that usually are composed of three layers and their core layer's thickness is higher and the outer layers are determinative in determination of the products strength and stiffness. The core layer is commonly made of honeycomb paper, corrugated paper and polyurethane etc. In this study, effects of face and adhesive types on mechanical properties of sandwich panels made from honeycomb paper were investigated. The variables included three types; beech face, poplar face and hardboard (S2S face, veneer less and adhesive type (two types; epoxy and PVA. Out of experimental panels specimens were cut and tested according to DIN E 326-1 standard. Mechanical properties of panels, included modulus of elasticity as well as modulus of rupture at the edge and surface (based on DIN EN 310 standard and Impact Bending Strength (IBS of the panels (based on ASTM D 3499 standard were measured. The gathered data were analyzed as completely randomized factorial design. Highest mechanical properties were reported for panels glued with epoxy resin and containing fiberboard at the middle. According to results, optimum condition of producing sandwich panels was observed in uses of epoxy resin and fiberboard S2S face, veneer less at the middle.

The paper production industry has a great impact on the environment which is mostly due to the use of raw materials (wood of conifers and deciduous trees, fillers (CaCO 3, additional materials (dyes, glue, binders, retentionaids, and chemicals (acids and bases. However, the greatest impact on the environmentis caused by the extensive water consumption. To produce 1 ton of paper up to 60 m3 of freshwater are necessary. The water is not the only resource needed in the production cycle. Besides, the consumption of electrical energy (approximately 10,000 MJ/t pap, waste paper (paper represents 35 % of waste, and air pollution (paper production and transport should be taken into consideration. In spite of the above mentioned environmental threats the paper still remains an important element of the everyday life and the use of modern information technology (personal computers, telefax, Internet has increased its demand and consumption. It is important that the paper is produced from natural materials which are later released into environment without significant environmental consequences. The technology of paper recycling and re-use is widely known and a must of any responsible and professional social environment. Digitisation has increased the consumption of electrical energy as a consequence of production, use and reprocessing of different devices. Unlike a written record, a digital record has no permanent value and the electromagnetic field has a negative effect on the digital records. Digital records have to be constantly updated and adjusted to the computer software and hardware. A book and its content represent a treasure and an invaluable part of the cultural heritage.

Genealogical Trees of Scientific Papers.

Waumans, Michaël Charles; Bersini, Hugues

2016-01-01

Many results have been obtained when studying scientific papers citations databases in a network perspective. Articles can be ranked according to their current in-degree and their future popularity or citation counts can even be predicted. The dynamical properties of such networks and the observation of the time evolution of their nodes started more recently. This work adopts an evolutionary perspective and proposes an original algorithm for the construction of genealogical trees of scientific papers on the basis of their citation count evolution in time. The fitness of a paper now amounts to its in-degree growing trend and a "dying" paper will suddenly see this trend declining in time. It will give birth and be taken over by some of its most prevalent citing "offspring". Practically, this might be used to trace the successive published milestones of a research field.

QoS Predictability of Internet Services

Science.gov (United States)

Bilski, Tomasz

The paper presents problems of QoS (Quality of Service) predictability of network services (mainly in WAN environment). In the first part we present general remarks on QoS predictability problem, mentioning some research projects and available resources. The main part of the paper deals with QoS predictability in long-term as well as short-term viewpoints. We will try to answer a question: is it possible to predict network QoS/performance level with a use of statistical data from the past? The term quality of service has many meanings ranging from the user's qualitative perception of the service to a set of quantitative connection parameters (RTT (Round Trip Time), throughput, loss packet rate) necessary to achieve particular service quality. In the paper we will mostly use the second meaning of the term based on RFC 2386 [1]. Analyzed, statistical data on Internet performance are taken from the IEPM (Internet End-to-end Performance Measurement) database.

Husserl’s theory of noematic sense

Nikolić Olga

2016-01-01

Full Text Available After Husserl’s transcendental turn and the discovery of the correlation between consciousness and the world the concept of the noema becomes one of the constant leitmotifs of Husserl’s philosophy. My paper will be devoted to the clarification of this concept and its implications for Husserl’s theory of sense. The leading question will be: How can the noema play the role of both the sense and the objective correlate of the intentional act? I will start with presenting the problematic of sense in Husserl’s phenomenology from the Logical Investigations to the Ideas I. The central part of my paper will be devoted to the influential debate regarding the interpretation of the noema. Finally, I intend to point out the most important ways in which the notion of the noema becomes enriched in later Husserl’s philosophy, as well as the difference between linguisitic and non-linguistic sense, based on the Analyses Concerning Passive and Active Synthesis. I hope to show that Husserl’s phenomenological theory of sense offers a valuable alternative to the exclusively language-oriented theories of sense. [This paper is the abridged and reworked version of my Master’s Thesis "Husser’s Notion of the Noema: The Phenomenological Theory of Sense" defended at KU Leuven in January 2016.

The aim of this study was to identify seminal Australasian Journal on Ageing papers published over 30 years through a Delphi consensus process. The main data collection was a three-round Delphi consensus study with 38 past and current members of the Australasian Journal on Ageing Editorial Board, Editorial Team and Management Committee. Three papers were agreed as top-ranking. One of the top-ranking articles was also highly cited. One article was published in the 1990 s, two in 2001. While it is difficult to judge how well the top-ranking papers represent seminal papers arising over 30 years, these papers do represent three different research strengths in Australasia, they do span three different disciplines, and they do reflect some of the diversity that characterises ageing research in Australasia over 30 years. © 2013 ACOTA.

Western Siberia leads slide in former U.S.S.R.'s oil production

1992-01-01

The huge western Siberian basin, which Moscow had counted on to ensure rising Soviet petroleum production into the next century, is in steady leading the sharp decline in the former U.S.S.R.'s total oil flow. New data indicate that western Siberia's 1991 crude and condensate production fell to less than 6.5 million b/d. That's down from nearly 7.5 million b/d in 1990 and a peak of 8.28 million b/d in 1988. This paper reports that such low production would make it difficult for Russia to meet the oil needs of other members of the new Commonwealth of Independent States, let alone earn substantial amounts of desperately needed hard currency from crude and refined products sales to foreign countries

The solvation sphere of halides in water has been investigated using a combination of extended x-ray absorption fine structure (EXAFS) and x-ray absorption near-edge structure (XANES) analysis techniques. The results have indicated that I{sup -} and Br{sup -} both have an asymmetric, 8 water molecule primary solvation spheres. These spheres are identical, with the Br{sup -} sphere about .3 {angstrom} smaller than the I{sup -} sphere. This study utilized near-edge analysis to supplement EXAFS analysis which suffers from signal dampening/broadening due to thermal noise. This paper has reported on the solvation first sphere of I{sup -} and Br{sup -} in water. Using EXAFS and XANES analysis, strong models which describe the geometric configuration of water molecules coordinated to a central anion have been developed. The combination of these techniques has provided us with a more substantiated argument than relying solely on one or the other. An important finding of this study is that the size of the anion plays a smaller role than previously assumed in determining the number of coordinating water molecules. Further experimental and theoretical investigation is required to understand why the size of the anion plays a minor role in determining the number of water molecules bound.

Cellulose nanofibers use in coated paper

Science.gov (United States)

Richmond, Finley

Cellulose Nanofibers (CNF) are materials that can be obtained by the mechanical breakdown of natural fibers. CNF have the potential to be produced at low cost in a paper mill and may provide novel properties to paper, paper coatings, paints, or other products. However, suspensions have a complex rheology even at low solid contents. To be able to coat, pump, or mix CNF at moderate solids, it is critical to understand the rheology of these suspensions and how they flow in process equipment; current papers only report the rheology up to 6% solids. Few publications are available that describe the coating of CNF onto paper or the use of CNF as an additive into a paper coating. The rheology of CNF suspensions and coatings that contain CNF were characterized with parallel-disk geometry in a controlled stress rheometer. The steady shear viscosity, the complex viscosity, the storage modulus, and the yield stress were determined for the range of solids or concentrations (2.5-10.5%). CNF were coated onto paper with a laboratory rod coater, a size press and a high speed cylindrical laboratory coater (CLC). For each case, the coat weights were measures and the properties of the papers were characterized. CNF water base suspension was found to be a shear thinning with a power law index of around 0.1. Oscillatory tests showed a linear viscoelastic region at low strains and significant storage and loss moduli even at low solids. The Cox Merz rule does not hold for CNF suspensions or coating formulations that contain CNF with complex viscosities that are about 100 times larger than the steady shear viscosities. Paper coating formulations that contain CNF were found to have viscosities and storage and loss moduli that are over ten times larger than coatings that contain starch at similar solids. CNF suspensions were coated on papers with low amount transferred on paper either at high solids or high nip loadings. The amount transferred appears to be controlled by an interaction of

Industrial radiography on radiographic paper

International Nuclear Information System (INIS)

Domanus, J.C.

1977-11-01

An investigation was performed to compare the quality of radiographic paper with that of X-ray film, after a review had been made of the rather scarce literature on the subject. The equipment used throughout the investigation is described, and characteristic curves for Agfa-Gevaert and Kodak papers exposed with different intensifying screens in the low and intermediate voltage range are reproduced. The relative speed, contrast and exposure latitude were computed from these curves. The quality of the radiographic image was checked on U/Al blocks and plates, Al and Fe blocks, and fiber-reinforced composites. Exposure charts for Al and Fe were made for various paper and screen combinations. Both the sharpness of the radiographic image as well as the influence of processing on speed and contrast were checked. Examples are given of the practical application of the paper for radiography of castings, weldings, solderings, assemblies, etc. (author)

Mixed waste paper as a fuel

International Nuclear Information System (INIS)

Kersletter, J.D.; Lyons, J.K.

1991-01-01

A successful recycling program requires several components: education and promotion, convenient collection service, and most importantly, a market for collected materials. In Washington state, domestic markets currently have, or are building, the capacity to use most of the glass, newsprint, aluminum, tin cans, and corrugated materials that are collected. Unfortunately, markets for mixed waste paper (MWP), a major component of the state's solid waste stream, have been slow to develop and are unable to absorb the tremendous volumes of material generated. The American Paper Stock Institute classifies MWP as low grade paper such as magazines, books, scrap paper, non-corrugated cardboard (boxboard/chipboard), and construction paper. When viewed as part of a curbside collection program MWP consists primarily of catalogs, binder paper, magazines, brochures, junk mail, cereal boxes, and other household packaging items. A comprehensive analysis of Washington State's solid waste stream showed that during 1988, Washington citizens generated approximately 460,000 tons of mixed waste paper. No small amount, this is equivalent to more than 10% of the total solid waste generated in the state, and is expected to increase. Current projections of MWP generation rates indicated that Washington citizens could discard as much as 960,000 tons of MWP by the year 2010 making it one of the single largest components of the state's solid waste stream. This paper reports on the use of MWP as fuel source

Pop Feminism: Televised Superheroines from the 1990s to the 2010s

2016-12-01

Full Text Available This paper analyses the construction of two superheroines, one from the 1990s (Buffy the Vampire Slayer and one from the 2010s (Jessica Jones. I contend that popular feminism has changed between the 1990s and the present and that this is evident in the representation of televised superheroines. While in the 1990s superheroines were more conformist, today they are more transparent in their feminist intentions. I suggest that this is due to contemporary cultural trends in the United States.

Full Text Available This paper gives a novel explanation of the integral equation of Abel’s type from the point of view of Mikusinski’s operational calculus. The concept of the inverse of Mikusinski’s operator of fractional order is introduced for constructing a representation of the solution to the integral equation of Abel’s type. The proof of the existence of the inverse of the fractional Mikusinski operator is presented, providing an alternative method of treating the integral equation of Abel’s type.

Final Technical Report of project: "Contactless Real-Time Monitoring of Paper Mechanical Behavior During Papermaking"

The early precursors of laser ultrasonics on paper were Prof. Y. Berthelot from the Georgia Institute of Technology/Mechanical Engineering department, and Prof. P. Brodeur from the Institute of Paper Science and Technology, both located in Atlanta, Georgia. The first Ph.D. thesis that shed quite some light on the topic, but also left some questions unanswered, was completed by Mont A. Johnson in 1996. Mont Johnson was Prof. Berthelot's student at Georgia Tech. In 1997 P. Brodeur proposed a project involving himself, Y. Berthelot, Dr. Ken Telschow and Mr. Vance Deason from INL, Honeywell-Measurex and Dr. Rick Russo from LBNL. The first time the proposal was not accepted and P. Brodeur decided to re-propose it without the involvement from LBNL. Rick Russo proposed a separate project on the same topic on his side. Both proposals were finally accepted and work started in the fall of 1997 on the two projects. Early on, the biggest challenge was to find an optical detection method which could detect laser-induced displacements of the web surface that are of the order of .1 micron in the ultrasonic range. This was to be done while the web was having an out-of-plane amplitude of motion in the mm range due to web flutter; while moving at 10 m/s to 30 m/s in the plane of the web, on the paper machine. Both teams grappled with the same problems and tried similar methods in some cases, but came up with two similar but different solutions one year later. The IPST, GT, INL team found that an interferometer made by Lasson Technologies Inc. using the photo-induced electro-motive force in Gallium Arsenide was able to detect ultrasonic waves up to 12-15 m/s. It also developed in house an interferometer using the Two-Wave Mixing effect in photorefractive crystals that showed good promises for on-line applications, and experimented with a scanning mirror to reduce motion-induced texture noise from the web and improve signal to noise ratio. On its side, LBNL had the idea to

BOOK REVIEW: A Student's Guide to Einstein's Major Papers A Student's Guide to Einstein's Major Papers

Science.gov (United States)

Janssen, Michel

2013-12-01

The core of this volume is formed by four chapters (2-5) with detailed reconstructions of the arguments and derivations in four of Einstein's most important papers, the three main papers of his annus mirabilis 1905 (on the light quantum, Brownian motion, and special relativity) and his first systematic exposition of general relativity of 1916. The derivations are given in sufficient detail and in sufficiently modernized notation (without any serious distortion of the originals) for an undergraduate physics major to read and understand them with far less effort than it would take him or her to understand (English translations of) Einstein's original papers. Each of these four papers is accompanied by a detailed introduction, which covers the conceptual development of the relevant field prior to Einstein's contribution to it and corrects some of the myths surrounding these papers that still have not been fully eradicated among physicists. (One quibble: though Kennedy correctly points out that the goal of the light quantum paper was not to explain the photoelectric effect, it is also not quite right to say that 'it was written to explain the Wien region of blackbody radiation' (p. xv). Einstein used this explanatory feat as the central argument for his light quantum hypothesis.) These four chapters then are the most valuable part of the volume. They could be used, independently of one another, but preferably in conjunction with Einstein's original texts, in courses on quantum mechanics, statistical mechanics, electrodynamics, and general relativity, respectively, to add a historical component to such courses. As a historian of science embedded in a physics department who is regularly called upon to give guest lectures in such courses on the history of their subjects, I can highly recommend the volume for this purpose. However, I would not adopt this volume as (one of) the central text(s) for a course on the history of modern physics. For one thing, chapter 1, which in
