  1. International conference on opportunities and challenges for water cooled reactors in the 21. century. PowerPoint presentations

    Water Cooled Reactors have been the keystone of the nuclear industry in the 20th Century. As we move into the 21st Century and face new challenges such as the threat of climate change or the large growth in world energy demand, nuclear energy has been singled out as one of the sources that could substantially and sustainably contribute to power the world. As the nuclear community worldwide looks into the future with the development of advanced and innovative reactor designs and fuel cycles, it becomes important to explore the role Water Cooled Reactors (WCRs) will play in this future. To support the future role of WCRs, substantial design and development programmes are underway in a number of Member States to incorporate additional technology improvements into advanced nuclear power plants (NPPs) designs. One of the key features of advanced nuclear reactor designs is their improved safety due to a reduction in the probability and consequences of accidents and to an increase in the operator time allowed to better assess and properly react to abnormal events. A systematic approach and the experience of many years of successful operation have allowed designers to focus their design efforts and develop safer, more efficient and more reliable designs, and to optimize plant availability and cost through improved maintenance programs and simpler operation and inspection practices. Because many of these advanced WCR designs will be built in countries with no previous nuclear experience, it is also important to establish a forum to facilitate the exchange of information on the infrastructure and technical issues associated with the sustainable deployment of advanced nuclear reactors and its application for the optimization of maintenance of operating nuclear power plants. This international conference seeks to be all-inclusive, bringing together the policy, economic and technical decision-makers and the stakeholders in the nuclear industry such as operators, suppliers

Benefits of PowerPoint presentation in classroom instruction as a means to improve classroom teaching in the developing countries are also discussed. The effectiveness of PowerPoint Presentation (PPT for teaching Technical Drawing concepts in Basic Technology was determined using a pretest-posttest, non-equivalent, non-randomized experimental group design. A 2x2x3 factorial design was employed. One hundred JSS 1 students (53 male and 47 female categorized into 29 high, 54 medium and 17 low achievers from two secondary schools in Abuja Metropolis formed the sample. The schools were randomly assigned to experimental and control groups. The experimental group was taught some selected concepts from Technical Drawing using PowerPoint Presentation (PPT while Chalkboard method (CB was used for the control group. A validated Technical Drawing Achievement Test (TDAT comprising a 25-item multiple-choice test was employed for data collection. The reliability coefficient of TDAT was .88 using Kuder-Richardson (KR-20. The hypotheses were tested using ANCOVA and Sidak post-hoc analysis. Results revealed that the students taught with PPT performed better than their counterparts taught with CB. Also, high achievers performed better than medium and low achievers respectfully. The PPT was found also to be gender friendly. Based on the findings, it was recommended that the use of PPT should be encouraged in Nigerian schools.

    Ram Rajesh J


    Full Text Available Information conveyed in seminars, project presentation or even in class rooms can be effective when slideshow presentation is used. There are various means to control slides which require devices like mouse, keyboard, or laser pointer etc. The disadvantage is one must have prior knowledge about the devices in order to operate them. This paper proposes two methods to control the slides during a presentation using bare hands and compares their efficiencies. The proposed methods employ hand gestures given by the user as input. The gestures are identified by counting the number of active fingers and then slides are controlled. Unlike the conventional method for hand gesture recognition which makes use of gloves or markers or any other devices, this method does not require any additional devices andmakes the user comfortable. The proposed method for gesture recognition does not require any database to identify a particular gesture. The experiment was tested under different kinds of light sources like incandescent bulb, fluorescent lamp and natural light.

    This paper examines the pervasive role of Microsoft’s presentation software PowerPoint as a genre of professional and organizational communication. Frequently, PowerPoint is not only used for the primary function it was initially designed for, i.e., facilitating live presentations, but also for...... alternative purposes such as project documentation. Its application in a neighboring domain, however, poses a functional dilemma: does the PowerPoint genre preserve the features of its primary function, i.e., presentation, or rather adapt to the new function, i.e., documentation? By drawing on a communication...... allows identification of three distinct PowerPoint subgenres, which differ in how they adapt to the function of project documentation. This paper contributes to organization studies by specifying the boundary conditions under which a genre of professional communication such as PowerPoint can be expected...

  6. Absinthism: a fictitious 19th century syndrome with present impact

    Lachenmeier Dirk W


    Full Text Available Abstract Absinthe, a bitter spirit containing wormwood (Artemisia absinthium L., was banned at the beginning of the 20th century as consequence of its supposed unique adverse effects. After nearly century-long prohibition, absinthe has seen a resurgence after recent de-restriction in many European countries. This review provides information on the history of absinthe and one of its constituent, thujone. Medical and toxicological aspects experienced and discovered before the prohibition of absinthe are discussed in detail, along with their impact on the current situation. The only consistent conclusion that can be drawn from those 19th century studies about absinthism is that wormwood oil but not absinthe is a potent agent to cause seizures. Neither can it be concluded that the beverage itself was epileptogenic nor that the so-called absinthism can exactly be distinguished as a distinct syndrome from chronic alcoholism. The theory of a previous gross overestimation of the thujone content of absinthe may have been verified by a number of independent studies. Based on the current available evidence, thujone concentrations of both pre-ban and modern absinthes may not have been able to cause detrimental health effects other than those encountered in common alcoholism. Today, a questionable tendency of absinthe manufacturers can be ascertained that use the ancient theories of absinthism as a targeted marketing strategy to bring absinthe into the spheres of a legal drug-of-abuse. Misleading advertisements of aphrodisiac or psychotropic effects of absinthe try to re-establish absinthe's former reputation. In distinction from commercially manufactured absinthes with limited thujone content, a health risk to consumers is the uncontrolled trade of potentially unsafe herbal products such as absinthe essences that are readily available over the internet.

  8. A century of the phage: past, present and future.

    Salmond, George P C; Fineran, Peter C


    Viruses that infect bacteria (bacteriophages; also known as phages) were discovered 100 years ago. Since then, phage research has transformed fundamental and translational biosciences. For example, phages were crucial in establishing the central dogma of molecular biology - information is sequentially passed from DNA to RNA to proteins - and they have been shown to have major roles in ecosystems, and help drive bacterial evolution and virulence. Furthermore, phage research has provided many techniques and reagents that underpin modern biology - from sequencing and genome engineering to the recent discovery and exploitation of CRISPR-Cas phage resistance systems. In this Timeline, we discuss a century of phage research and its impact on basic and applied biology. PMID:26548913

  18. Expanding the use of Microsoft PowerPoint. An overview for radiologists

    Most radiologists need to give a lecture, present research or speak at a scientific meeting at some stage in their career. In our technologically advanced world, electronic presentations have become the norm and are almost universally expected. Microsoft PowerPoint is by far and away the most commonly used computer-based presentation package. As a result most radiologists have developed at least a modicum of PowerPoint expertise but many lack the time or inclination to develop these skills further. The purpose of this article is to explain how to expand the use of PowerPoint with freely available resources from the internet, to highlight websites where useful information on advanced PowerPoint techniques can be found, and to discuss extended functions of PowerPoint likely to be of interest to radiologists such as poster design

  19. Re-presenting science: Visual and didactic practice in nineteenth-century chemistry

    Ritter, Christopher Owen

    This dissertation argues that there is no divide between scientific and didactic practice in chemistry: they are one in the same. Similarly, it argues that representation is inherently re-presentation, which is to say, there is also no divide between the production and the reproduction of scientific knowledge. These arguments are based upon visual practices of nineteenth-century chemistry, in which chemists made knowledge through careful practices of visual representation. The historical argument begins with two post-alchemical systems of representation, the chemical characters of Jean Henri Hassenfratz and Pierre Auguste Adet, introduced in the Nomenclature chimique of 1787, and John Dalton's atomic symbols. It argues that although the symbols of both systems did not survive, the visual practices within which they were situated did. Focusing on the teaching of American chemists Benjamin Silliman and Robert Hare, it examines chemical didactics after Dalton, including the visual practices of Dalton's colleague, William Wollaston. The larger context of visual practices in the nineteenth-century figures in the history of chemistry. Anschauung, or reflection on direct observation or perception, was at the core of Johann Heinrich Pestalozzi and Friedrich Frobel's reforms in early education. It also influenced chemical practice. Frobel's kindergarten modeling practices, the kindergarten movement in mid-century England, and Anschauungsunterricht, or teaching through images, have historical links with chemical representation, in particular the use of graphical formulas by Alexander Crum Brown and Edward Frankland. Crum Brown's formulas and Frankland's Lecture Notes for Chemical Students form the center of an investigation of the didactic, rhetorical, typographical, and personal factors involved in representational practices in chemistry, and the production of chemical knowledge on the page. These aspects of chemical practice in turn influenced chemical atomism. The

  20. PowerPoint in the classroom.


    Points of View (POV) addresses issues faced within life science education. Cell Biology Education has launched the POV feature to present two or more opinions published in tandem on a common topic. We consider POVs to be "Op-Ed" pieces designed to stimulate thought and dialog on significant educational issues. Each author has the opportunity to revise a POV after reading drafts of the other POVs. In this issue, we ask the question, "Is PowerPoint the best instructional medium to use in your class?" Everyone seems to have an opinion on Microsoft, but the intellectual merits of using PowerPoint (or similar software) is a growing question as states and institutions put more and more money into information technology and distance learning. Four POVs are presented: 1) David Keefe and James Willett provide their case why PowerPoint is an ideal teaching software. Keefe is an educational researcher at the Center for Technology in Learning at SRI International. Willett is a professor at George Mason University in the Departments of Microbial and Molecular Bioscience; as well as Bioinformatics and Computational Biology. 2) Kim McDonald highlights the causes of PowerPointlessness, a term which indicates the frequent use of PowerPoint as a crutch rather than a tool. She is a Bioscience Educator at the Shodor Education Foundation, Inc. 3) Diana Voss asks readers if PowerPoint is really necessary to present the material effectively or not. Voss is a Instructional Computing Support Specialist at SUNY Stony Brook. 4) Cynthia Lanius takes a light-hearted approach to ask whether PowerPoint is a technological improvement or just a change of pace for teacher and student presentations. Lanius is a Technology Integration Specialist in the Sinton (Texas) Independent School District. The authors span the range of teaching experiences and settings from which they bring different points of view to the debate.

  1. Earthquake swarms in West Bohemia / Vogtland: at present and one century ago

    Hrdličková, M.; Fischer, T.


    The region of Vogtland / northwest Bohemia is known as one of the most interesting European regions with the occurrence of earthquake swarms. Detailed seismicity data are available for the last 50 years since several seismic networks have been built. For studying the seismicity of the previous period it is necessary to rely on macroseismic observations and for the 1st half of the 20th century on only rare records of activity from distant seismic stations. Better understanding of the present seismic activity is enabled also by deepening our knowledge of historical activity, especially for earthquake swarms in the second half of the 19th century, for which there are many macroseismic records from Czech and German sides. However, a complete catalog of the historical events focused on this area is missing. In our study we used the macroseismic data from the Czech side to create a preliminary catalog of earthquakes from the period 1897 to 1908. We found a significant heterogenity in the available resources in terms of interchanging macroseismic observations and seismic events. We used cluster analysis for converting the macroseismic dataset to seismic catalog and found greatest concentration of earthquakes in the years 1897, 1900, 1903 and 1908, which corresponds to the published data on historical seismicity in West Bohemia/Vogtland. Similar to the recent earthquake swarms, the analyzed swarms showed episodic character which is typical by several phases of activity interrupted by periods of seismic calm. Next we compare our catalog with the newest version of Earthquake catalog for Germany and Adjacent Areas for the years 800 to 2008 (Leydecker, 2011). We find some differences between the number of events reported in both catalogs. In some cases our preliminary catalog gives more events (e.g. 95 compared to 13 in 1903), while in other cases our catalog contains less events than the Leydecker's catalog (e.g. 49 compared to 88 in 1897). We analyze the possible causes of

The use of this program, however, comes at a cost, because it is not just a different and neutral way of teaching. Like the use of any technology, PowerPoint affects not only the way we present and teach, but also the way we think, learn and understand.

  8. [Presentation of pyoderma gangraenosum in a dermatologic atlas of the early 19th century].

    Kuner, N; Hartschuh, W


    Pyoderma gangrenosum was first described in 1930 by Brunsting, Goeckermann and O'Leary. Nevertheless we found some illustrations in an atlas on dermatology, published by Marie-Nicolas Devergie in the first half of the 19th century, which appear to be pyoderma gangrenosum. In addition to discussions of typical syphilitic affections of the skin, Devergie's "Clinique de la Maladie Syphilitique" includes illustrations of gangrenous ulcers, which appeared unexpectedly after local and systemic therapy with mercury. Devergie interpreted those enlarging ulcers as a side effect of mercury therapy. Thus we were able to find evidence of pyoderma gangrenosum more than 100 years before first description in 1930. The etiology of this clinical picture is still unsettled. The favorite postulate has been a bacterial genesis which was the subject of numerous publications until the 1960s. PMID:10969411

  9. Comparison of 19th Century and Present Concentrations and Depositions of Ozone in Central Europe

    WEIDINGER, Tamás


    Full Text Available Ozone, one of the most important trace gases in atmosphere was discovered byChristian Friedrich Schönbein (1799–1886, a chemistry professor at the University of Basel. Themethod developed by him was used from the middle of nineteenth century until the 1920’s inmuch of the world. The measurement method is based essentially on the color-change of anindicator test paper. We obtained records for ozone measured in the Habsburg Empire usingSchönbein’s method for analyze the long term environmental processes. According to recordskept in the Habsburg Empire, ozone was measured at more than twenty sites between 1853–1856.On the territory of the Kingdom of Hungary, ozone was measured at Szeged, Buda andSelmecbánya (Schemnitz, Banska Štiavnica among others. Long term datasets are available fromBuda (1871–1898 and Ó-Gyalla (Altdala, Hurbanovo, 1898–1905. Ozone was measured duringboth day- and nighttime. Additionally meteorological variables (like air temperature, relativehumidity, air pressure, wind speed, cloud cover, precipitation were also observed several times aday. The data reported in the yearbooks were collected and evaluated in this study to reconstructthe ozone dataset. Depending on concentrations and deposition velocity over different vegetatedsurfaces the ozone deposition can be estimated. The reliability of estimations and reconstructedozone deposition values are also discussed. Finally ozone datasets from the 19th and 21st centuryand the differences in ozone concentration and deposition between rural and urban areas arecompared. Ozone concentrations and deposition are found to be approximately three times highernow than in the 19th century.

  12. Hawaii’s “7 by 7” for School Health Education: A PowerPoint Presentation on Integrating the National Health Education Standards With Priority Content Areas for Today’s School Health Education in Grades Kindergarten Through 12

    Beth Pateman, HSD, MPH


    Full Text Available School-based health education can help young people develop the knowledge, skills, motivation, and support they need to choose health-enhancing behaviors and resist engaging in behaviors that put them at risk for health and social problems and school failure. The health of school-age youth is significantly associated with their school achievement. However, in the midst of today’s increased emphasis on school accountability in the areas of reading, writing, and mathematics, subject areas such as health education tend to receive less prominence in the school curriculum. Recalling their own lackluster school experiences related to health topics, decision makers may not realize that today’s skills-based school health curriculum involves a highly interactive and engaging approach to promoting good health and preventing the most serious health problems among youth. Health education is one important component of a coordinated school health program that includes health education, physical education, school health services, nutrition services, school counseling and psychological services, a healthy school environment, school promotion for faculty and staff, and involvement of family and community members. The purpose of this PowerPoint presentation — Healthy Keiki, Healthy Hawaii: Hawaii's "7 by 7" for School Health Education — is to educate health and education decision makers, teachers, parents, and community members on how Hawaii has integrated seven health education standards with seven priority health content areas to create an effective approach to school health education in grades kindergarten through 12. The goal of Hawaii’s “7 by 7” curriculum focus is to ensure that all of Hawaii’s keiki (children have well-planned opportunities at school to become fit, healthy, and ready to learn.

  15. The Black Sea Wave Energy: The Present State and the Twentieth century Changes

    Galabov, Vasko


    In this paper we present a study of the present state of the Black Sea wave energy. The studies of other authors are based on the use of input data from atmospheric reanalysis or a downscaling of such reanalysis. Instead of reanalysis data, we use input data from the operational limited area numerical weather prediction model ALADIN. We showed that the estimations of the Black Sea wave energy based on reanalyses deviate significantly from the real potential. We showed also that the highest values of the mean annual wave power flux is between 4.5 and 5.0 kW/m2 and the near shore areas with the highest wave energy potential are the southernmost Bulgarian coast and the coast of Turkey north of Istanbul. While we showed that the wind data from the reanalysis are not useful for the estimation of the actual wave energy potential, we claimed that the reanalysis data is useful to study the long term changes of the wave energy of the Black Sea. We used the 10m winds from the recent ERA-20C reanalysis, which covers the...

  16. 21st Century Extravehicular Activities: Synergizing Past and Present Training Methods for Future Spacewalking Success

    Moore, Sandra K.; Gast, Matthew A.


    Neil Armstrong's understated words, "That's one small step for man, one giant leap for mankind." were spoken from Tranquility Base forty years ago. Even today, those words resonate in the ears of millions, including many who had yet to be born when man first landed on the surface of the moon. By their very nature, and in the the spirit of exploration, extravehicular activities (EVAs) have generated much excitement throughout the history of manned spaceflight. From Ed White's first space walk in June of 1965, to the first steps on the moon in 1969, to the expected completion of the International Space Station (ISS), the ability to exist, live and work in the vacuum of space has stood as a beacon of what is possible. It was NASA's first spacewalk that taught engineers on the ground the valuable lesson that successful spacewalking requires a unique set of learned skills. That lesson sparked extensive efforts to develop and define the training requirements necessary to ensure success. As focus shifted from orbital activities to lunar surface activities, the required skill-set and subsequently the training methods, changed. The requirements duly changed again when NASA left the moon for the last time in 1972 and have continued to evolve through the Skylab, Space Shuttle; and ISS eras. Yet because the visits to the moon were so long ago, NASA's expertise in the realm of extra-terrestrial EVAs has diminished. As manned spaceflight again shifts its focus beyond low earth orbit, EVA success will depend on the ability to synergize the knowledge gained over 40+ years of spacewalking to create a training method that allows a single crewmember to perform equally well, whether performing an EVA on the surface of the Moon, while in the vacuum of space, or heading for a rendezvous with Mars. This paper reviews NASA's past and present EVA training methods and extrapolates techniques from both to construct the basis for future EVA astronaut training.

  19. Comparing early twentieth century and present-day atmospheric pollution in SW France: A story of lichens

    Lichens have long been known to be good indicators of air quality and atmospheric deposition. Xanthoria parietina was selected to investigate past (sourced from a herbarium) and present-day trace metal pollution in four sites from South-West France (close to Albi). Enrichment factors, relationships between elements and hierarchical classification indicated that the atmosphere was mainly impacted by coal combustion (as shown by As, Pb or Cd contamination) during the early twentieth century, whereas more recently, another mixture of pollutants (e.g. Sb, Sn, Pb and Cu) from local factories and car traffic has emerged. The Rare Earth Elements (REE) and other lithogenic elements indicated a higher dust content in the atmosphere in the early twentieth century and a specific lithological local signature. In addition to long-range atmospheric transport, local urban emissions had a strong impact on trace element contamination registered in lichens, particularly for contemporary data. - Highlights: ► We compared metal concentrations registered in contemporary and early 1900's lichens. ► In the past, As, Pb and Cd were enriched due to coal combustion. ► Nowadays, a new mixture of enriched contaminants (Sb, Sn, Pb and Cu) was evidenced. ► REE originated from local bedrock and proved an increased dust deposition in the past. ► Lichens recorded both local and long-range atmospheric contamination. - Using lichens registration, past (As, Pb, Cd) and recent (Sb, Sn, Cu) atmospheric pollution from local and long-range transport, as well as dust deposition, was evidenced in SW France.

  20. Changing black carbon transport to the Arctic from present day to the end of 21st century

    Jiao, Chaoyi; Flanner, Mark G.


    Here we explore how climate warming under the Representative Concentration Pathway 8.5 (RCP8.5) impacts Arctic aerosol distributions via changes in atmospheric transport and removal processes. We modify the bulk aerosol module in the Community Atmosphere Model to track distributions and fluxes of 200 black carbon-like tracers emitted from different locations, and we conduct idealized experiments with and without active aerosol deposition. Changing wind patterns, studied in isolation, cause the Arctic burdens of tracers emitted from East Asia and West Europe during winter to increase about 20% by the end of the century while decreasing the Arctic burdens of North American emissions by about 30%. These changes are caused by an altered winter polar dome structure that results from Arctic amplification and inhomogeneous sea ice loss and surface warming, both of which are enhanced in the Chukchi Sea region. The resulting geostrophic wind favors Arctic transport of East Asian emissions while inhibiting poleward transport of North American emissions. When active deposition is also considered, however, Arctic burdens of emissions from northern midlatitudes show near-universal decline. This is a consequence of increased precipitation and wet removal, particularly within the Arctic, leading to decreased Arctic residence time. Simulations with present-day emissions of black carbon indicate a 13.6% reduction in the Arctic annual mean burden by the end of the 21st century, due to warming-induced transport and deposition changes, while simulations with changing climate and emissions under RCP8.5 show a 61.0% reduction.

  1. ICRP past, present, and future: quo vadis ICRP 60? Radiological protection at the start of the 21st century

    The principles of radiation protection as discussed by the International Commission on Radiological Protection (ICRP) have undergone continuous further development since their first definitions. Considerations and recommendations always have been based on ethical aspects of radiation protection and the effects of radiation. In the seventies of the 20th century, the principles were elaborated which are applied today, the two main aspects being the collective dose principle and cost - benefit analysis. They constitute the basis of today's yardsticks in applied radiological protection and its optimization. The present debate, also within ICRP, is about new approaches in radiological protection, changing from the collective principle to a more individual approach. This implies the introduction of new criteria, which may be referred to as dose limits for protective measures, and which could be justified on grounds of natural background radiation. In this way, the 1990 recommendations of ICRP, with their complex case-based definitions and goals of protection, could give way to a simplified, workable system with optimized goals of protection.

    Full Text Available As was the case at the conference, "Humanities professions in the knowledge society", the Director of Humanities and Philology Studies at the UOC, Isidor Marí, presents this Dossier, and the subsequent virtual debate, with the aim of gaining useful conclusions, with specific repercussions on the organisation of the degree studies and its professional projection, especially at this time, which requires study plans to be redesigned in line with the Bologna process. In the author's opinion, we can only make the right operative decisions when we are able to understand the transformations taking place in the humanistic culture framed by the knowledge society, and to do so, debate has to be opened in which students, graduates, academics, researchers, professionals and analysts can all take part.In this article, Isidor Marí analyses the tensions and contradictions that arise when attempts are made to relate the concepts of the professional world, Humanities and the knowledge society. Firstly, neither are Humanities a profession nor the study of Humanities seen by students or society to be adaptable to the definition of professional profiles. However, this highlights an important paradox, as the culture economy, (and, thus, occupations in the cultural sector, is growing increasingly throughout western societies. Likewise, in terms of the relationship between Humanities and the knowledge society, the author describes and analyses how there currently coexist voices foreseeing the worst alongside those that see information and communications technologies opening the way for an enormously positive transformation in human civilisation and a new cultural era.

  16. Hydrological Cycle in the Danube basin in present-day and XXII century simulations by IPCCAR4 global climate models

    Lucarini, Valerio; Kriegerova, Ida; Speranza, Antonio; 10.1029/2007JD009167


    We present an intercomparison and verification analysis of 20 GCMs included in the 4th IPCC assessment report regarding their representation of the hydrological cycle on the Danube river basin for 1961-2000 and for the 2161-2200 SRESA1B scenario runs. The basin-scale properties of the hydrological cycle are computed by spatially integrating the precipitation, evaporation, and runoff fields using the Voronoi-Thiessen tessellation formalism. The span of the model simulated mean annual water balances is of the same order of magnitude of the observed Danube discharge of the Delta; the true value is within the range simulated by the models. Some land components seem to have deficiencies since there are cases of violation of water conservation when annual means are considered. The overall performance and the degree of agreement of the GCMs are comparable to those of the RCMs analyzed in a previous work, in spite of the much higher resolution and common nesting of the RCMs. The reanalyses are shown to feature severa...

  2. More than a century of bathymetric observations and present-day shallow sediment characterization in Belfast Bay, Maine, USA: Implications for pockmark field longevity

    Brothers, L.L.; Kelley, J.T.; Belknap, D.F.; Barnhardt, W.A.; Andrews, B.D.; Maynard, M.L.


    Mechanisms and timescales responsible for pockmark formation and maintenance remain uncertain, especially in areas lacking extensive thermogenic fluid deposits (e.g., previously glaciated estuaries). This study characterizes seafloor activity in the Belfast Bay, Maine nearshore pockmark field using (1) three swath bathymetry datasets collected between 1999 and 2008, complemented by analyses of shallow box-core samples for radionuclide activity and undrained shear strength, and (2) historical bathymetric data (report and smooth sheets from 1872, 1947, 1948). In addition, because repeat swath bathymetry surveys are an emerging data source, we present a selected literature review of recent studies using such datasets for seafloor change analysis. This study is the first to apply the method to a pockmark field, and characterizes macro-scale (>5 m) evolution of tens of square kilometers of highly irregular seafloor. Presence/absence analysis yielded no change in pockmark frequency or distribution over a 9-year period (1999-2008). In that time pockmarks did not detectably enlarge, truncate, elongate, or combine. Historical data indicate that pockmark chains already existed in the 19th century. Despite the lack of macroscopic changes in the field, near-bed undrained shear-strength values of less than 7 kPa and scattered downcore 137Cs signatures indicate a highly disturbed setting. Integrating these findings with independent geophysical and geochemical observations made in the pockmark field, it can be concluded that (1) large-scale sediment resuspension and dispersion related to pockmark formation and failure do not occur frequently within this field, and (2) pockmarks can persevere in a dynamic estuarine setting that exhibits minimal modern fluid venting. Although pockmarks are conventionally thought to be long-lived features maintained by a combination of fluid venting and minimal sediment accumulation, this suggests that other mechanisms may be equally active in

  4. Stellar Presentations (Abstract)

    Young, D.


    (Abstract only) The AAVSO is in the process of expanding its education, outreach and speakers bureau program. powerpoint presentations prepared for specific target audiences such as AAVSO members, educators, students, the general public, and Science Olympiad teams, coaches, event supervisors, and state directors will be available online for members to use. The presentations range from specific and general content relating to stellar evolution and variable stars to specific activities for a workshop environment. A presentation—even with a general topic—that works for high school students will not work for educators, Science Olympiad teams, or the general public. Each audience is unique and requires a different approach. The current environment necessitates presentations that are captivating for a younger generation that is embedded in a highly visual and sound-bite world of social media, twitter and U-Tube, and mobile devices. For educators, presentations and workshops for themselves and their students must support the Next Generation Science Standards (NGSS), the Common Core Content Standards, and the Science Technology, Engineering and Mathematics (STEM) initiative. Current best practices for developing relevant and engaging powerpoint presentations to deliver information to a variety of targeted audiences will be presented along with several examples.

  8. Paper presentation abstract: The multiple meanings and cultural aspects of the own-home garden in the early 20th century Sweden

    Jakobsson, Anna


    Gardening has multiple meanings depending on where and how it is performed as well as what purpose it is attributed. This paper will discuss the meanings and cultural aspects of own-home gardens in the early 20th century Swedish urban context. Stately loans were paid out in order for people to be able to build houses with gardens, so called own-homes, in the countryside or in the outskirts of cities in the early 1900s. A home of one's own, with a garden, had a positive effect on health and so...

  9. Historical mapping reveals causes and temporal patterns of woodland contraction in Austur-Skaftafellssýsla from the 12th century AD to present

    Sigurmundsson, Friðþór S.; Gísladóttir, Guðrún; Erlendsson, Egill; Þorbjarnarson, Höskuldur


    Land-cover changes in Iceland over the last millennium encompass birch (Betula pubescens) woodland depletion and extensive soil erosion. Yet few studies have focused on spatial change of birch woodland coverage in Iceland over centuries and why and how the woodland depletion took place. The main objectives of this study are: (1) to map the woodland distribution today in Austur-Skaftafellssýsla (3041 km2) in southern Iceland; (2) to map woodland holdings over a period of 900 years from eleventh. AD 1100 to the early 20th century; (3) explain the relative impacts of socio-economic and natural forces on woodland cover over this period. We use a combined approach of historical reconstruction from diverse written archives, GIS techniques and field work. The woodland in Austur-Skaftafellssýsla now covers 73.2 km2 (2.5% of the study area). The woodland holdings, 44 in total, are regularly listed in the church inventories from 1179 to 1570 and are owned by the church. In the first complete register for the district in 1641 the woodland holdings were 73, owned and used by 58 estates, and distributed across Austur-Skaftafellssýsla. All the main patches of woodland remain today, with the exception of four minor woodlands which were exhausted near the end of the 19th century. The woodland was used for firewood and charcoal making as well as grazing during the study period but, crucially, in most cases only one estate had authority over each holding, none were commons. The main driving force behind the development of woodlands was socio-economic, rather than natural, where the form of ownership was fundamental for the fate of the woodland. Harsh climate and volcanism were not directly responsible for woodland depletion. The latter half of the 19th century was the period of greatest woodland loss. This period coincides with considerable expansion in livestock numbers, especially sheep and associated all year around grazing, at a time when the Little Ice Age culminated in

  13. Fire history of dark needle coniferous forests in Pechora-Ilych nature reserve since second half of XIX century to present time

    A. A. Aleynikov


    Full Text Available A study of the vegetation cover current state in any area should start from detailed investigation of its land-use history. Historic factors are of particular importance for forest ecosystems of protected nature areas as usually they are regarded as models and their history is neglected. The article describes fire history of the piedmont area of Pechora-Ilych biosphere nature reserve based on high resolution remote sensing data analysis and historical records. Such method allows reconstruction of forest fires back to 150 years ago. Field research of the tree stands age structure is needed to reveal older fires. 89 burns of 78 893 ha total area were detected, which is 11 % of the piedmont area of the reserve. The burns are distributed unevenly across the area: 76 % are in the Ilych river basin and the rest are in the Pechora river basin. All burns are classified into 4 types according to the periods during which they happened. Burned areas in both river basins changed during these periods: major part of the forest cover in the Ilych basin was damaged before the reserve was established, in the Pechora river basin -in the first decade after its foundation. Only 20 burns are precisely dated out of 73 burns happened in the XX century. Causes are also not determined for all fires. Probably both natural (lightning and anthropogenic factors caused fires. Known anthropogenic fires are allocated to settlements and floating rivers and cover huge areas (thousands and tens of thousands hectares. Natural fires are at distant watershed areas and are significantly smaller (tens and hundreds hectares.

  14. The assessment of river basin and flood management from early twentieth century to the present on the lower Siret River (Romania)

    Salit, F.; Beltrando, B.; Zaharia, L.


    The river basin management and flood depends on the politico-historical, economic and environmental context in which it is thought. There is a similar evolution in Romania, where political developments have had as much impact on flood management than hydro-climatic events. The aim of this work is to understand of management systems in a diachronic logic in Romania from the beginning of the 20th century to the Communist period and to accession to the European Union. This work focuses on the lower Siret River. The Siret catchment is one of the last major tributaries of the Danube River east of the Carpathians and the most important of Romania in terms of flow and drainage area. To study the assessment of river basin management, a GIS was constructed using a series of Romanian and Russian topographic maps extending over the period 1916-1990 and Google earth images from 2009 and 2010. The study of the current period was enhanced by field observations (records of existing dykes, testimonials ...) from 2010-2011. Finally, this study is based on the technical literature for the regularization of rivers and the various reports made over this period. Three periods were identified: the major floods of 1970 and 2005 marked a turning point in the logical management of river basin and especially in the fight against flood. From the beginning of the period to 1970, dyke protection was sporadic: they are intended primarily to protect the villages directly threatened by recurrent flood. In 1970 a major flood (3500 m3/s) occurred on the lower Siret and other minor floods in succession from 1970 to 1975. By 1976 a national plan was drawn up to fight against the harmful effects of water. The entire sector of the lower Siret River and its major tributaries is arranged, a network of levees protects not only the villages but also all economic assets in this sector, namely the agricultural land, the main wealth of the region. In 2005 an exceptionally large flood (4650 m3/s) affected the

    Lejeune, Ruben


    When writing papers, it is frequently necessary to add citations. A frequently used tool to facilitate this process is Zotero. Currently one can add citations using the Zotero Word integration extension to a Word document, however there is not yet a tool to do so in PowerPoint – despite the fact that in many settings this would be very desirable. This project solves this problem. The first difficulty was that this was the first time I had to analyze a software project of this magnitude (speci...

  17. Ministerial Presentation: Sudan [International Ministerial Conference on Nuclear Energy in the 21. Century: Addressing Energy Needs and Environmental Challenges, Beijing (China), 20-22 April 2009

    First, I would like to thank the IAEA and OECD for sponsoring this conference and the government of China for hosting the conference. It gives me great pleasure to address this conference. This is a very important conference dealing with nuclear power in the 21st century. Sudan as a developing nation experiences an increase in the energy demand of its people. This is due to an increase industrialization and urbanization. Sudan with the assistance of the IAEA has initiated a planning study for long term energy supply and demand. This study showed that by the year 2020 an energy gap between energy supply and demand will occur. According to this study Sudan need to consider the nuclear option as part of an energy mix. Accordingly, Sudan with the help of the IAEA has started a technical cooperation program aiming at understanding the necessary infrastructure needed for a nuclear power program. To implement this program two committees were formed. A technical committee to address the technical requirement for the project and a high administrative committee to give the necessary political support. Utilizing nuclear energy for peaceful purposes requires strong commitment towards issues of safety, security and safeguards of nuclear and radioactive material. As part of the infrastructure requirement, in Sudan we started the amendments of the legal and regulatory framework. A new atomic energy act is being drafted. The most important features of this act are that: It provide for the establishment of a separate independent regulatory authority which will deal with all regulatory aspects of radioactive sources and nuclear material. The act also covers areas like emergency preparedness, nuclear security, liability and others. The legal requirement of nuclear program is the adherences to certain international legal instrument. A national committee from the ministries of justice, foreign affairs and science and technology was formed to advice on the country position regarding the

  18. Ministerial Presentation: Republic of Korea [International Ministerial Conference on Nuclear Energy in the 21. Century: Addressing Energy Needs and Environmental Challenges, Beijing (China), 20-22 April 2009

    I would first like to extend my sincere appreciation and gratitude for allowing me to speak in this forum where the most influential decision-makers of the energy policy and the experts in nuclear power have gathered together to discuss the important energy issues facing us today. This forum is indeed crucial, and should be held on a continuing basis if we are to solve the colossal challenges we face in energy, as represented by the depletion of fossil fuel energy and the climate change. I sincerely hope that this forum will take a serious look at the future role of nuclear power as the global energy source, and provide a basis for a meaningful discussion on issues related to energy on a global scale. Due to the recent fluctuation in oil prices and issues related to climate change, the world is paying a renewed attention to nuclear energy that is not only a stable source of energy but produces less greenhouse gas. The Korean government announced the national agenda, so-called ''Low-carbon, Green-growth'' to join the global efforts to tackle climate change. The Korean government recognizes the importance of nuclear power technology in achieving the Low-carbon Green-growth strategy and strongly supports its research and development activities. As part of our effort for this, Korea will lower the national dependency rate on fossil fuels such as oil and gas, while significantly increasing the share of nuclear energy and renewable energy. It has been half a century since nuclear power was first introduced to Korea. So far, the Korean government has heavily invested in research and development of nuclear energy, believing in the unlimited possibility of nuclear power. As a result, Korea started the commercial operation of Gori No. 1 nuclear power plant in 1978 which has grown to 20 nuclear power plants to this day. Today, Korea ranks 6th in the world in nuclear energy development. Korea has gone through continuous innovation in nuclear energy technology during the past

  20. Present state-of-the-art and strategy for development of geothermal energy in the world at the end of X X century

    A review of the present state-of-the-art for direct application of geothermal energy is given in the paper as follows: 1) For direct application of middle and low-temperature waters for district heating, in agriculture, aquaculture and different industrial processes and balneology; 2) For electricity production. A prognosis for future possible application of geothermal energy in 2020 is given according to two scenarios: i) based on the present compromise ecological politics, with an annual rise of 4% for electricity production and 2-3% for direct application of geothermal energy; and ii) based on the rigid ecological politics, with an annual rise of 6-8% for electricity production and 3% for direct application of geothermal energy.

  1. Course Management Systems: Traveling Beyond Powerpoint Slides Online

    Gauthier, A. J.; Impey, C. D.


    Course management systems (CMS) like WebCT, Blackboard, Astronomica, etc., have reached and surpassed their tipping point in higher education. They are no longer a technology-trendy item to use in a course, but rather an expected supplement to undergraduate courses. There is a well known disconnect between the student population of ''digital natives'' (1) and higher education instructors, the ''digital immigrants'' (1). What expectations and technology skills do the new generations of undergraduates have? How can instructors easily meet their students' needs? What needs do instructors have and what resources are available to meet those needs? In the past, instructors would create their own HTML web pages to post class materials like PowerPoint slides, homework, and announcements. How does an instructor-created web resource differ from a secure university run CMS? How can you make your university or college's CMS system into a productive learning tool and not just a repository for class materials and grades? How can the astronomy instructor benefit from integrating a CMS into their course? What are common student attitudes regarding CMS usage in a course? How are instructors using CMSs in innovative ways? Where on your campus can you get free help designing and implementing a CMS resource for your students? This presentation aims to answer these questions. Extensive literature reviews, formal surveys, case study reports, and educational research from the instructional technology community inform our astronomy teaching community of the answers. Highlights from innovative systems and uses of CMSs in undergraduate Astro 101 classrooms will be presented. Resources and further references will be made available as handouts. (1) M. Prensky.

  3. Grainsize Patterns and Bed Evolution of the Rhone River (France): A Present-day Snapshot Following a Century and a Half of Human Modifications

    Michal, T.; Parrot, E.; Piegay, H.


    Over the past 150 years the Rhône River has been heavily altered by human infrastructures. The first wave (1860 - 1930) of modifications consisted of dikes and groynes designed to narrow the channel and promote incision in order to facilitate navigation. A second period (1948 - 1986) involved the construction of a series of canals and dams for hydroelectricity production. These works bypass multiple reaches of the original channel and drastically reduce the discharge and sediment load reaching them. A comprehensive study underway is aimed at describing the present-day morphology of the Rhone along its 512 km length from its source at Lake Geneva to its sink at the Mediterranean Sea and quantifying the role of management works in the evolution to its current state. Grainsize distributions and armour ratios were determined using a combination of Wolman counts on bars and in shallow channels and dredge samples collected from a boat in navigable reaches. Long profiles were constructed from historical bathymetric maps and bathymetric data collected between 1950 - 2010. Differential long profiles highlighting changes in bed elevation due to sediment storage and erosion were analyzed for three different periods: post-channelization, post-dam construction, and a recent period of major floods. Results show a complex discontinuous pattern in grainsize associated with hydraulic discontinuities imposed by dams. The D50 for bypass reaches is 45 mm compared to a D50 of 34 mm in the non-bypass reaches. The lower D50 as well as a finer tailed distribution in non-bypass reaches reflects fining associated with storage upstream of dams. Armour ratios are on average around 2 but are notably higher for reaches in the middle section of the Rhone. The average incision rate was 1.8 cm/yr for the period of post-channelization and 1.2 cm/yr following dam construction, suggesting the post-dam Rhone was already partially armoured due to incision associated with channelization preceding dam

    -by-step program to get rid off all its nuclear arsenals and to be verified internationally via lAEA. At the General conference of IAEA in 2006, Libya has declared its intent to introduce nuclear power in the energy mix for the production of electricity and water declination. Leading companies were called to Libya to present their latest nuclear technology. Libya also has signed agreements with many countries on peaceful application of nuclear Energy (France, Russian Federation and Argentina). Steps are taken for the implementation of these agreements and the lAEA is helping in this program through technical cooperation department. We ask all nuclear technology holders not to put obstacles in front of the transfer of nuclear technologies for peaceful application according to NPT. All states have the right to produce and use nuclear energy as long as they have safeguards agreement with IAEA and additional protocol in force. We all know the benefits that a country and the world can have when applying nuclear energy peacefully and hence we all should work together toward these goals. I wish to this conference success and looking forward for wide peaceful application of nuclear power.

    , its implementation is more complex, complicated and slower than it appears. Implementation requires constant coordination among all partners participating in project. We are glad that there are already some steps accomplished which I want to share with you. After the political declaration of the three Baltic States on the construction of a common nuclear power plant Lithuania started to consider project related environmental issues. The Environmental Impact Assessment Program (EIA) was approved by the Lithuanian Ministry of Environment on November 15th, 2007 after extensive national and international commenting. In August 2008 EIA report has been prepared and presented to the public. Environmental impact assessment evaluated construction and operation of a new nuclear power plant in Lithuania with an approximate electric power of 3400 MW. The environmental impact assessment did not find any environmental or social impacts of such significance, caused by construction or operation of the new NPP, that they could not be accepted or mitigated to an acceptable level. Lithuania has established the National investor company LEO LT which is responsible for the implementation and development of New Nuclear Power Plant project. LEO LT is going to bear 100% of Lithuania's participation share in the project. The step forward to project implementation was establishing a new LEO LT subsidiary - 'Visaginas nuclear power plant'. A new subsidiary will perform all the new NPP project related preparatory works. While discussing nuclear power expansion we have to think about expansion of human resources as well. The National Energy Strategy gives the national priority to ensure timely preparation of specialists for work in the new nuclear power plant as of the phase of mounting its technological equipment. In this respect Lithuania has developed a National programme for the preparation of nuclear energy specialists for the years 2008-2015. Taking into account all those mentioned

  6. century drying

    Cook, Benjamin I.; Smerdon, Jason E.; Seager, Richard; Coats, Sloan


    Global warming is expected to increase the frequency and intensity of droughts in the twenty-first century, but the relative contributions from changes in moisture supply (precipitation) versus evaporative demand (potential evapotranspiration; PET) have not been comprehensively assessed. Using output from a suite of general circulation model (GCM) simulations from phase 5 of the Coupled Model Intercomparison Project, projected twenty-first century drying and wetting trends are investigated using two offline indices of surface moisture balance: the Palmer Drought Severity Index (PDSI) and the Standardized Precipitation Evapotranspiration Index (SPEI). PDSI and SPEI projections using precipitation and Penman-Monteith based PET changes from the GCMs generally agree, showing robust cross-model drying in western North America, Central America, the Mediterranean, southern Africa, and the Amazon and robust wetting occurring in the Northern Hemisphere high latitudes and east Africa (PDSI only). The SPEI is more sensitive to PET changes than the PDSI, especially in arid regions such as the Sahara and Middle East. Regional drying and wetting patterns largely mirror the spatially heterogeneous response of precipitation in the models, although drying in the PDSI and SPEI calculations extends beyond the regions of reduced precipitation. This expansion of drying areas is attributed to globally widespread increases in PET, caused by increases in surface net radiation and the vapor pressure deficit. Increased PET not only intensifies drying in areas where precipitation is already reduced, it also drives areas into drought that would otherwise experience little drying or even wetting from precipitation trends alone. This PET amplification effect is largest in the Northern Hemisphere mid-latitudes, and is especially pronounced in western North America, Europe, and southeast China. Compared to PDSI projections using precipitation changes only, the projections incorporating both

    generation that will result to sustainable and reasonably-priced electricity rates. We are however, confronted with the challenge that, on the average, about 60% of energy sources utilized in the power generation mix come from fossil fuels primarily oil, coal and natural gas. Moreover, the Philippines still has one of the highest power rates in Asia. That is yet another basis as to why we are seriously considering nuclear power since it provides a relatively competitive generation cost with the cheapest power source which is coal. Among power sources with high upfront costs like wind and solar, nuclear power has the cheapest generation cost. As we work to bring about access to affordable and sufficient electricity for every Filipino, we keep in mind that energy utilization must be consistent with the need for the protection and preservation of our planet's fragile ecosystems. Therefore, we are aiming to reduce the country's contribution to carbon dioxide emissions. The Philippines has taken proactive action by laying the groundwork to shift to a renewable energy system. As a signatory to the UN Framework Convention on Climate Change and the subsequent Kyoto Protocol, we are fully committed to doing our part in addressing global warming even though we are not legally bound to impose a national limitation on emissions. In our efforts to ensure that the use of energy must not damage our environment, we have to deal with the fact that renewable energy development is still costly. As such, nuclear power presents an appealing energy option since the complete nuclear power chain emits the least carbon which is about the same as wind and hydropower. For a developing and non oil-producing country like the Philippines, these are the merits we see in utilizing nuclear energy in power generation. We have already undertaken a nuclear power program in the past. Political circumstances then resulted to the mothballing of the Bataan Nuclear Power Plant, our lone nuclear power plant which

  8. Ministerial Presentation: Sri Lanka. Presentation by Tissa Vitarana [International Ministerial Conference on Nuclear Energy in the 21. Century: Addressing Energy Needs and Environmental Challenges, Beijing (China), 20-22 April 2009

    Thank you, Mr. Chairman for giving me the opportunity to address this distinguished audience at short notice. I would also like to thank the Government of China and the China Atomic Energy Authority together with the IAEA and the Nuclear Energy Agency of the OECD for hosting and organizing this second ministerial meeting on nuclear energy. It takes place at a time when the world is faced with an energy crisis and also an environmental crisis. Besides cost considerations, dependence on fossil fuels is no longer feasible because of their impact on climate leading to global warming with all the adverse consequences for all forms of life on this planet. Therefore, from the point of view of generating electricity on a large scale without carbon emissions, nuclear energy is the need of the hour. This meeting is addressing the main issues that arise in expanding the use of nuclear energy as a source of power, such as fuel supply, waste management, infrastructure development, technology availability and environmental aspects. In addition by providing time for ministerial presentations the current experience and needs of the various countries are being surfaced and shared. Before discussing some issues pertaining to Sri Lanka, I wish to express my agreement with the statement made by the Vice Prime Minister of China who clearly emphasized the need for a total ban on nuclear weapons, which was supported by speakers from several other countries. The statement attributed to US President Barak Obama that he is prepared to work towards reducing nuclear arms in the USA is also welcome. Further, the right of every country to resort to peaceful use of nuclear energy for generating power should be respected so long as they conform to the regulations of the IAEA, including the Non Proliferation Treaty (NPT). I wish to share with the learned delegates a few issues pertaining to Sri Lanka as a country which has not yet taken a firm decision to turn to nuclear energy as a part of its

  10. The 21st Century as Whose Century?

    David Scott


    Full Text Available Macro-analysis and East-West encounter are shown through consideration of objective yet subjective constructed concepts for the international system and international economy in the 21st century. Three paradigms are considered, namely the 21st century as the ‘Pacific Century’, as ‘China’s Century’ and as the ‘Asian Century’. Overlaps are shown between these three paradigms, as also developments in time, and gradually shift in geographical location. The ‘Pacific Century’, and its associated Rimspeak, was the paradigm emerging in the late 1970s, knitting together America’s West Coast and the Japanese economy. By the late 1980s this was already shifting to talk of the 21st century likely to be an ‘Asian Century’ model, mark-1, based on the Pacific Asia dynamism shown by the ‘Asian Tigers’ and Japan. However, the Asian financial crash of 1997-8, and the economic downturn in Japan, meant that such an ‘Asian Century’ seemed premature as the 21st century arrived. Instead, it was China’s economic growth that seemed most evident, and with it the concept of the 21st century as ‘China’s Century’. However, in turn that has already been modified during the first decade of the century by India’s arrival as a rapidly growing economy. Consequently the 21st century as ‘China’s Century’ and as ‘India’s Century’ has been combined into talk of an ‘Asian Century’, mark-2.

    Hilyer, Lee Andrew


    Recent research on learning from multimedia presentations has indicated that the current way many people prepare their slide presentations may actually hinder learning. Considering the ubiquity of the PowerPoint presentation in business and in education, presenters should be concerned whether or not their audience members are effectively receiving the information they wish to impart. This issue is of special import for librarians who teach, as they often must convey complex information in a very limited amount of time.

  16. Ministerial Presentation: Bangladesh. Statement by Arch. Yeafesh Osman [International Ministerial Conference on Nuclear Energy in the 21. Century: Addressing Energy Needs and Environmental Challenges, Beijing (China), 20-22 April 2009

    It is indeed a great pleasure and honour for me to have the opportunity to participate in this august gathering of International Ministerial Conference on Nuclear Energy in the 21st century. At the outset I avail of this opportunity to express my heartfelt gratitude to Chinese Atomic Energy Agency (CAEA) and the Government of the People's Republic of China (PRC) for the initiative and interest of hosting this important event in Beijing. I express my profound sense of gratefulness for the firm commitment, moral, material and intellectual support of the IAEA and its Member States which enabled organization of this important conference. The history of IAEA is a history of solidarity and the joint actions of the member states, an icon of joint collaboration for 'Atom For Peace Program'. I am confident that this conference will allow the participants to address development and emerging issues relevant to the role of nuclear power in providing clean and sustainable energy for the 21st Century. The conference will also provide an opportunity to review the status and prospects of nuclear power to carry forward the positive momentum to further raise the profile of Nuclear Energy. Respected Delegates, We all share a common understanding that nuclear science and technology is now conceived as a potential instrument of change and can play a decisive and pivotal role in efforts of achieving the much coveted goal of poverty alleviation. For ensuring sustainable development energy security is the most important strategic issue for all in the 21st Century. Global warming from greenhouse gases caused by excessive and imprudent use of fossil fuels, is a problem we must overcome together to achieve sustainable development. Meanwhile, Asia is displaying a high growth rate in both population and economic development.

  18. The quantum century

    Physicists often complain that the phrase quantum leap'' is used erroneously, if harmlessly, by people to describe a large jump or change. Yet this month the physics community is celebrating the 100th anniversary of what must count as the beginning of the biggest quantum leap in the history of science, whichever way you define the phrase. On 14 December 1900 Max Planck presented a paper on the radiation emitted by a black body at a meeting of the German Physical Society in Berlin. This event is generally taken to mark the start of the quantum century, though few people realized it at the time - not even Planck himself. (U.K.)

    Full Text Available Vikas Seth, Prerna Upadhyaya, Mushtaq Ahmad, Vijay MogheDepartment of Pharmacology, Mahatma Gandhi Medical College, Jaipur, Rajasthan, IndiaPurpose: To assess students’ perceptions of the impact of PowerPoint (PPT presentations in lectures in comparison to the traditional chalk and talk method and lectures using ­transparencies and overhead projector (TOHP. The study analyzes the preferences for teaching aids of medical students versus dental students.Methods: Second year medical and dental undergraduates were asked to fill in a nine-item questionnaire about their perceptions of the three lecture delivery methods. Following analysis of the questionnaire the students were interviewed further. The results were analyzed separately for medical and dental students to see if there was any difference in their perceptions.Results: The majority of the medical students (65.33% preferred PPT presentations, while 15.16% of students preferred the lectures using chalkboard, and 19.51% preferred TOHP for teaching (P < 0.001. Of the dental students: 41.84% preferred chalkboard, 31.21% preferred TOHP, and 25.85% students preferred PPT presentations in the lectures (P < 0.05. Some important comments of the students were also recorded on interview which could be valuable for the medical teachers.Conclusion: The medical students clearly preferred the use of PPT presentations while the dental students did not. The study does not bring out evidence based superiority of any lecture delivery method. It appears that in the hands of a trained teacher any teaching aid would be appropriate and effective. This highlights the need for formal training in teaching technologies to develop good presentation skills and thus motivate the students.Keywords: audiovisual aids, medical education, lecture delivery methods, PowerPoint presentations, OHP, chalkboard

  20. The management century.

    Kiechel, Walter


    In 1886, addressing the nascent American Society of Mechanical Engineers, Henry R. Towne proposed that "the management of works" be considered a modern art--thereby heralding the Management Century, when management as we know it came into being and shaped the world in which we work. Kiechel, a past editorial director of Harvard Business Publishing, elucidates the three eras that punctuate this period: the years leading up to World War II, during which scientific exactitude gave wings to a new managerial elite; the early postwar decades, managerialism's apogee of self-confidence and a time when wartime principles of strategy were adapted, sometimes ruthlessly, to the running of companies; and the 1980s to the present, years that saw fast-moving changes, disequilibrium, and a servitude to market forces but also ushered in globalism, unprecedented innovation, and heightened expectations about how workers are to be treated. Along the way he examines the contributions of thinkers such as Frederick Taylor, Elton Mayo, Peter Drucker, and Michael Porter. What lies ahead? Perhaps the biggest challenge facing the 21st-century company, Kiechel posits, is to truly free the spark of human imagination from the organization's tidal pull toward the status quo. There's almost always a better way, he concludes--and management will continue to seek it. PMID:23155998

  2. Ministerial Presentation: Egypt. Speech of H.E. Dr. Hassan Younes [International Ministerial Conference on Nuclear Energy in the 21. Century: Addressing Energy Needs and Environmental Challenges, Beijing (China), 20-22 April 2009

    First, I would like to express my sincere appreciation to our host country China, for making possible this International Ministerial Conference. Also, I would like to commend the efforts of the International Atomic Energy Agency (IAEA) and Nuclear Energy Agency (NEA) of the (OECD) in organizing this important conference. Egypt was one of the countries to realize that nuclear power could be utilized to secure the supply of electricity and fresh water. Several attempts haven't been materialized in the last 3 decades due to different factors. Recently, Egypt has reconsidered the nuclear power as an option to supply electricity. Egypt was motivated to consider the introduction of nuclear power by the following factors: Steadily increasing demand for electricity; Egypt is not a rich country of indigenous fossil energy resources, and almost full utilized its hydro power resources; Instability in the prices of fossils energy resources. Introducing the nuclear power alongside other forms of energy resources will maximize the usage of these resources; Nuclear energy is a technically and economically viable source of energy. In the 21st century, these reasons have not only retained their validity, but have been also reinforced by the developments which have been taking place. Egypt electricity demand will continue to increase in the foreseeable future. Currently, electricity reaches over 99% of the Egypt's population and it is planned to add 58 GW by the year 2027. The challenges of meeting these increasing demand will have to be met in the best possible ways within the prevailing constraints. These include: Increase the share of renewable energy, in electricity generation to 20% by the year 2020. By the year 2020 the total wind farm capacities will be at least 7200 MW, of which 63% would be constructed by private sector. A 140-MW solar-thermal power plant is currently under construction, and is expected to be connected to the grid by the end of year 2010; Conservation of

  13. Ministerial Presentation: United States of America. Ambassador Schulte's Remarks on Behalf of Energy Secretary Chu [International Ministerial Conference on Nuclear Energy in the 21. Century: Addressing Energy Needs and Environmental Challenges, Beijing (China), 20-22 April 2009

    , as currently structured, has established two working groups, both with significant involvement from the IAEA. The first addresses infrastructure development and seeks to help states begin implementing the guidance conveyed in the Milestones document. The second working group addresses reliable nuclear fuel services as a viable alternative to the acquisition of sensitive fuel cycle technologies. We need to take full advantage of these and other exchanges to seek solutions and innovations to bring about the new framework proposed by President Obama. Bilateral civil nuclear cooperation. Besides these multilateral avenues, new entrants have much to gain through bilateral cooperation Governments with long nuclear energy histories can help states avoid mistakes made in the past while advancing sustainable programs. The United States has a long history of civil nuclear cooperation dating back to President Eisenhower's historic ''Atoms for Peace'' speech. A half century later, our commitment to civil nuclear cooperation remains strong. We have agreements that provide a framework for U.S. nuclear cooperation with nearly 50 countries and the IAEA. In addition, the Department of Energy, including the National Nuclear Security Administration, and the Nuclear Regulatory Commission have dozens of arrangements with their counterpart institutions) in countries with both developed and emerging programs) on issues such as energy planning, infrastructure development, site selection, regulatory body strengthening, new reactor safety evaluation and regulation, reactor operation, decommissioning, and waste management. Industry partners can also provide often-overlooked training and consulting services to help states with the long-term, strategic planning necessary for the century-long commitment that accompanies a nuclear power plant. For our part, the United States is committed to ensuring that all nuclear firms compete exclusively on the merits of th

  14. Ministerial Presentation: Indonesia. Statement by the Delegation of the Republic of Indonesia [International Ministerial Conference on Nuclear Energy in the 21. Century: Addressing Energy Needs and Environmental Challenges, Beijing (China), 20-22 April 2009

    Allow me, on behalf of my delegation, to express our gratitude to the IAEA, OECD and China Atomic Energy Agency for organizing this Conference. It is indeed a great pleasure to participate in this important Conference. In the midst of nuclear renaissance in the 21st century, the convening of this Conference is not only timely, but also significant to address challenges and opportunities related to global energy security. Entering the 21st century, we continue to witness the rising expectations for nuclear energy in different parts of the world, especially for generating electricity. As a country with more than 230 million people, Indonesia needs huge amount of energy. One of the alternative primary energy resources to meet its rising demand for energy in the future is nuclear energy. As a faithful state party to the NPT and a member of the IAEA, Indonesia has long been a strong advocate of promoting nuclear energy for peaceful purposes. Article IV of the NPT clearly recognizes the inalienable right of every state party to develop nuclear energy for peaceful purposes without discrimination. As long as it is aimed and used for peaceful purposed and under the full comprehensive safeguards of the IAEA, this right should be fully respected by all States without any interference. Indonesia has fully committed to strengthen nuclear non-proliferation within the framework of the NPT. In this regard, since the last few years, Indonesia has put in place integrated safeguards which covers both the comprehensive safeguards agreement and the additional protocol of the IAEA to its nuclear facilities. In the context of combating nuclear terrorism, Indonesia has also worked with the IAEA as well as through bilateral and regional cooperation to undertake measures and improvements in strengthening nuclear safety and security of its nuclear facilities. In the context of the civil use of nuclear energy, Indonesia has enacted Law No. 10 of 1997 on Nuclear Energy, which underscores the

  15. Ministerial Presentation: Nigeria. Statement by His Excellency Dr. Alhassan Bako Zaku [International Ministerial Conference on Nuclear Energy in the 21. Century: Addressing Energy Needs and Environmental Challenges, Beijing (China), 20-22 April 2009

    On behalf of the Nigerian Delegation, it is my pleasure to extend warm congratulations to you, Minister Li, for the able and masterful manner you have piloted the affairs of this Ministerial Conference on Nuclear Energy in the 21st Century. I also wish to congratulate the International Atomic Energy Agency (IAEA) for its foresight in organizing this topical and timely conference; particularly at a time that there appears to be signs of global nuclear power renaissance. To the Government and good People of the Peoples Republic of China, I thank you for your usual display of rare hospitality and being such wonderful hosts. And to all of you participants and members of the respective national delegations, I bring to you special felicitations and goodwill from President Umaru Musa Yar' Adua and the good people of the Federal Republic of Nigeria. It is my understanding that the major theme of this conference is aimed at providing participants, an opportunity to assess and review the status and prospects of nuclear power in the 21st Century, and what it entails in contributing towards achieving an optimal global energy mix. Obviously, these issues will in broad terms include an assessment of the progress in the evolution of technology vis-a-vis the global environmental concerns, assurance of nuclear fuel supply and waste management, as well as the thorny issues of nuclear non-proliferation. Furthermore, this conference is also designed to offer a forum to assess the challenges, viability and potential benefits for developing countries which are considering the introduction of nuclear power into their national energy mix. It is my delegation's expectation that open and frank discussions on these issues, and the proper identification of the requisite actions needed to maintain the positive momentum that nuclear power has witnessed in recent years, will form the basis for the outcome of this meeting. It is generally acknowledged that energy usage is a major index of human

  16. Seventeenth-century indivisibles revisited


    The tremendous success of indivisibles methods in geometry in the seventeenth century, responds to a vast project: installation of infinity in mathematics. The pathways by the authors are very diverse, as are the characterizations of indivisibles, but there are significant factors of unity between the various doctrines of indivisible; the permanence of the language used by all authors is the strongest sign. These efforts do not lead to the stabilization of a mathematical theory (with principles or axioms, theorems respecting these first statements, followed by applications to a set of geometric situations), one must nevertheless admire the magnitude of the results obtained by these methods and highlights the rich relationships between them and integral calculus. The present book aims to be exhaustive since it analyzes the works of all major inventors of methods of indivisibles during the seventeenth century, from Kepler to Leibniz. It takes into account the rich existing literature usually devoted to a singl...

    On behalf of the Government of Japan, I would like to offer my warmest congratulations on the successful holding of the International Ministerial Conference on Nuclear Energy in the 21st Century, here in Beijing. The importance of nuclear energy as a measure against global warming. We are currently facing serious challenges. It is vital to the prosperity of humanity that all countries strive for coordination and cooperation to resolve those issues such as scarcity of food, poverty, and terrorism, in addition to the economic crisis which has shaken up the world economy since last year. In particular, measures against global warming are key issues, to which all countries must unite and respond promptly, effectively and sustainably over an extended period. At the Annual Meeting of the World Economic Forum (Davos Meeting) in this January, Prime Minister of Japan, Mr. Taro Aso, mentioned the goal of reducing the global greenhouse-gas emissions at least by half, by the year of 2050. He stressed that the Post-Kyoto framework should be all inclusive to achieve this goal, with all the big emitters joining as responsible partners. The current year is a crucial one, in which to establish the framework for 2013 and beyond. The cooperation of all countries is required more than ever. I believe that, in order to achieve a significant reduction in global greenhouse-gas emissions while ensuring secure energy supply, the expansion of the peaceful use of nuclear energy is essential, along with the maximum implementation of other effective measures such as energy conservation, energy efficiency improvement and the use of renewable energy. Recently, this role of nuclear energy has been widely recognized over the world. In the 4th Assessment Report, published in 2007 by the Intergovernmental Panel on Climate Change (IPCC), nuclear energy, which emits minimal greenhouse gases, is described as one of major mitigation technologies in the energy supply area. The International Energy Agency

    our efforts and resources. In this context, let me point out that at present only a small fraction of the current fleet of power reactors is subject to a rigorous administration of IAEA safeguards. While this is undoubtedly important, such an approach alone is unlikely to be sustainable in producing the desired results particularly in the context of the expected large scale growth in nuclear power deployment. It is thus necessary to find technology-based solutions that provide an integrated answer to the issues of safety, security and proliferation while producing large scale nuclear power in a sustainable and eco-friendly manner. In India, we are, indeed, working on an approach that would enable us to maximise the role nuclear power can play in meeting our energy needs, consistent with the energy resource profile at our command. At the same time, we are also pursuing development of technologies that would address the concerns in the background of large scale deployment of nuclear power. In my presentation later in this Conference, I would cover this aspect in some detail. Several dimensions of our current nuclear power programme are highlighted in the exhibition organised by Nuclear Corporation of India during this Conference. While we are pursuing our indigenous development of nuclear technologies to meet our national requirements, we are indeed encouraged in speeding up realisation of our energy security with minimum carbon dioxide emissions through additionalities that are now possible as a result of opening up of international civil nuclear co- operation. Concurrently, we also stand ready to share our experience with friendly countries. This experience is likely to be more relevant and beneficial to them as compared to other available options. Mr. Chairman, the world needs more focussed work on developing relevant technologies and equipment. India's 220 MWe Pressurised Heavy Water Reactors with advanced safety features and high level of reliability could be of

  1. Ministerial Presentation: Russia. Development of Nuclear Power in Russia [International Ministerial Conference on Nuclear Energy in the 21. Century: Addressing Energy Needs and Environmental Challenges, Beijing (China), 20-22 April 2009

    On behalf of the General Director of the State Corporation of the Russian Federation 'Rosatom' I am honored to deliver this presentation 'Development of Nuclear Power in Russia'. 1. Today nuclear power maintains the position of one of the basic power sources worldwide. A total of 438 nuclear power reactors with installed capacity of 372 GW (e) were operational in 2008. Share of nuclear generation is ∼14% of the total electricity produced. Long-term predictions of global energy are contradictory that reflects both popular attitudes and attempts to solve all the problems on the fly. 2. In 2008 g. Ten NPPs with installed capacity of 23.2 GW generated 162 billion kW.h of electricity. The average capacity factor was 79.5 percent. 3. The basic parameters of state policy for development of fuel and energy complex in Russia in nuclear industry complex are: Growth of installed capacity in Russia (in European Russia >30%), stable increase of energy generation (≥4 percent per year) and ensuring the baseload with capacity factor ≥85 percent; Step-by-step transition starting from 2020 to a new technological platform based on fast breeder reactors with closed nuclear fuel cycle; Broadening the scope of NPP capacities to include small and medium-scale capacity to supply energy to isolated energy zones in Russia and developing economies of the world. The Roadmap for NPP build in Russia has been elaborated, including preliminary deadlines and sites for new units build up to 2020. 4. Today the backbone of nuclear power in Russia is pressurized water reactors with thermal neutrons and open fuel cycle. Fuel supply to NPP with these reactor types is based on natural uranium mining and enrichment. Modern NPPs are safe, environmentally friendly and - notwithstanding the deferred solution of irradiated fuel management - generate competitive electric power. Russian technological engineering is based on VVER reactor similar to PWR with certain specific features. The strategy

  2. Using Microsoft PowerPoint as an Astronomical Image Analysis Tool

    Beck-Winchatz, Bernhard


    Engaging students in the analysis of authentic scientific data is an effective way to teach them about the scientific process and to develop their problem solving, teamwork and communication skills. In astronomy several image processing and analysis software tools have been developed for use in school environments. However, the practical implementation in the classroom is often difficult because the teachers may not have the comfort level with computers necessary to install and use these tools, they may not have adequate computer privileges and/or support, and they may not have the time to learn how to use specialized astronomy software. To address this problem, we have developed a set of activities in which students analyze astronomical images using basic tools provided in PowerPoint. These include measuring sizes, distances, and angles, and blinking images. In contrast to specialized software, PowerPoint is broadly available on school computers. Many teachers are already familiar with PowerPoint, and the skills developed while learning how to analyze astronomical images are highly transferable. We will discuss several practical examples of measurements, including the following: -Variations in the distances to the sun and moon from their angular sizes -Magnetic declination from images of shadows -Diameter of the moon from lunar eclipse images -Sizes of lunar craters -Orbital radii of the Jovian moons and mass of Jupiter -Supernova and comet searches -Expansion rate of the universe from images of distant galaxies

  4. Statisticians of the centuries

    Seneta, E; Crépel, P; Fienberg, S; Gani, J


    Statisticians of the Centuries aims to demonstrate the achievements of statistics to a broad audience, and to commemorate the work of celebrated statisticians. This is done through short biographies that put the statistical work in its historical and sociological context, emphasizing contributions to science and society in the broadest terms rather than narrow technical achievement. The discipline is treated from its earliest times and only individuals born prior to the 20th Century are included. The volume arose through the initiative of the International Statistical Institute (ISI), the principal representative association for international statistics (founded in 1885). Extensive consultations within the statistical community, and with prominent members of ISI in particular, led to the names of the 104 individuals who are included in the volume. The biographies were contributed by 73 authors from across the world. The editors are the well-known statisticians Chris Heyde and Eugene Seneta. Chris Heyde is Pro...

  5. A Century of Antivenom

    Lovreček, Dijana; Tomić, Siniša


    Because it primarily affects the poor in undeveloped parts of the world where medical care is often inadequate and insufficient, envenomation is considered a neglected public health issue, despite the existence of antivenom therapy for more than a century. This article provides an overview of the epidemiological situation for important venomous animals, together with achievements in the production, control, technological progress and safety of antivenoms since their discovery.




    IN an excavated pit at the side of an expressway in Shandong’s Linzi are visible 2,000-year-old remains of horses and wooden carriages. The horse skeletons are on their side, in an attitude of motion. The pit was discovered in the late 20th century, when the expressway was being built. These early ancestors of modern transport, no longer "road-worthy," are now protected historic artifacts.

    Full Text Available This paper traces the development of news discourse across the 20th century ihrough a case study ofthe coverage of three expeditions to the South Pole: Captain Scott in 1912, Sir Edmund Hillary in 1958, and Peter Hillary in 1999. The way the news about the three expeditions reached New Zealand media serves as a framework and an illustration to examine three related issues: how technology has changed the time and place dimensions of news delivery; the consequent and concomitant shifts in news presentation; and associated changes in how humans have understood time and place. News values remain the same at a broad level across the century, but different in detail. Nationalism is obtrusive, but its focus shifts. In news practice, the deadline and the scoop drive the news in al1 three periods, but the scooping medium shifts from press to radio to television. The lapse between an event and its reporting shrinks exponentially from months to hours to minutes. The design of newspaper front pages changes radically, and news language compresses. There are social impacts, with newsworthy figures receiving closer exposure and the audience being cast in a more voyeuristic role.

  9. New Century, New Prospects



    @@ Nuclear weapons changed the world of the 20th century. Their powerful force rewrote history. Nuclear bombs dropped on Japan by the United States accelerated the collapse of Japanese militarism and hastened the end of World War Ⅱ. The West led by the United States and the East bloc led by the Soviet Union started a bitter nuclear arms race that mutually assured destruction. The balance of terror between the two blocs stabilized in the Cold War and prevented the world from actual armed conflict, thus maintaining a long-term but occasionally uneasy peace in Europe and the world.

  12. A century of physics

    Bromley, D Allan


    In this amazing tour d'horizon, D. Allan Bromley uses the occasion of the centenary of the American Physical Society to reflect upon the growth of physics over the past 100 years, its fragmentation into numerous subdisciplines, the impact physics has had upon modern technology, and the re-emergence of the fundamental unity of the discipline in recent years. Hundreds of historical illustrations accompany the text. Bromley conveys much of the excitement and wonder that research in physics generated in the 20th century and asks what new things are in store in the next century. He covers such topics as relativity and quantum mechanics, the Manhattan project, superconductivity, transistors and the revolution brought about by solid-state electronics, protein folding, the uses of nuclear and atomic physics in biology and medicine, plate tectonics, the expansion of the universe and the Big Bang, and gravitational radiation. Bromley, the Sterling Professor of the Sciences and Dean of Yale University, served as Assista...

  20. New Methods of Presenting Scale the Universe Concepts

    Adkins, J.


    Traditional scale of the universe activities involve building a scale model solar system, expressing distances in light travel time, and doing powers-of-ten animations. Free NASA materials will provide a sorting/ordering activity to teach this concept in a different way and at the same time introduce vocabulary and concepts involving some of the most distant objects in the universe. In addition, the author has used two novel methods of teaching universe scaling concepts: using a video of a drive representing the distance to a nearby star translates the distance concept into a more personal time-based experience, and a new version of a scale the universe powerpoint that uses power-of-1000 slides to compress each view of the universe into a single pixel of the next slide to help visualize the vast scales encompassing the universe and how far humanity's influence actually extends.

  1. Theodore E. Woodward Award: spare me the PowerPoint and bring back the medical textbook.

    Southwick, Frederick S


    A tutorial for 4(th) year medical students revealed absent long-term retention of microbiology and infectious disease facts taught during the 2(nd) year. Students were suffering from the Ziegarnik effect, the loss of memory after completion of a task. PowerPoint lectures and PowerPoint notes combined with multiple-choice questions may have encouraged this outcome; this teaching format was also associated with minimal use of the course textbook. During the subsequent year, active learning techniques, Just-in-Time Teaching (JiTT) and Peer Instruction (PI) were used, and instructors specifically taught from the textbook. Essays and short answer questions were combined with multiple-choice questions to encourage understanding and recall. Performance on the National Board Shelf exam improved from the 59(th) percentile (2002-2004) to the 83(rd) percentile (2005), and textbook use increased from 1.6% to 79%. This experience demonstrates that strategies incorporating active learning and textbook use correlate with striking improvement in medical student performance. PMID:18528495

  4. The craft of scientific presentations critical steps to succeed and critical errors to avoid

    Alley, Michael


    The Craft of Scientific Presentations, 2nd edition aims to strengthen you as a presenter of science and engineering. The book does so by identifying what makes excellent presenters such as Brian Cox, Jane Goodall, Richard Feynman, and Jill Bolte Taylor so strong. In addition, the book explains what causes so many scientific presentations to flounder. One of the most valuable contributions of this text is that it teaches the assertion-evidence approach to scientific presentations. Instead of building presentations, as most engineers and scientists do, on the weak foundation of topic phrases and bulleted lists, this assertion-evidence approach calls for building presentations on succinct message assertions supported by visual evidence. Unlike the commonly followed topic-subtopic approach that PowerPoint leads presenters to use, the assertion-evidence approach is solidly grounded in research. By showing the differences between strong and weak presentations, by identifying the errors that scientific presenters ty...

I show in this article that presentism, the doctrine that only what is present exists, is in conflict with modern relativistic cosmology and recent advances in neurosciences. I argue for a tenseless view of time, where what we call `the present' is just an emergent secondary quality arising from the interaction of perceiving self-conscious individuals with their environment. I maintain that there is no flow of time, but just an ordered system of events.

    Full Text Available The given article is aimed at considering multimedia presentation potential and its influence on strengthening classroom teacher-student interaction. In the article the importance of using this kind of activity in the study process is pointed in connection with educational state policy on the one hand. On the other hand, gained students’ skills as a final result of work with presentations met employers’ demand for both parent and world labour-markets and bring competitive benefit to the candidates. Scientific novelty and results. Multimedia presentation is considered as a specific complex of classroom activities. The students are oriented on the self analysis and presentation assessment. It is shown that well-organized process of peer students’ assessment allows to simultaneously helping in solving the didactic and methodical problems. To this purpose the system of assessment criteria should be developed. It has to be clear for students for making assessment feasible and time-saving. The example of a possible variant of criteria system is described; quality of the presentations prepared by students can be defined based on such system criteria. The author also analyzed software products of the three main platforms (Windows, Linux, MacOs which have different tools and allow to follow users’ needs for creating presentations. In the article there is a comparative table of the two most popular software development: the program Microsoft PowerPoint and the web-service Prezi for realizing the relevance of their use in the study process. Practical significance of the present article concludes in author’s suggestions of some recommendations for presentation potential use as a tool of improving pedagogical interaction process with contemporary students. 

  8. Detergents of the 21st century

    Ho Tan Tai Louis


    Full Text Available Detergents of the 21st century will depend on evolutions in household appliances, in substrates and in consumer needs. In addition, the environmental constraints, which become more and more stringent, will also play an important role, particularly in the formulations. Surfactants, which constitute one of the main raw materials in detergents, will have to be more environmentally friendly with increasing criteria of biodegradability and renewable materials. Builders (phosphates or zeolithes, heavy metal complexants (EDTA and bleaching agents (combination perborate/TAED are also expected to be replaced by biodegradable compounds, with better performances and lower costs. The real raw materials of the detergents of the 21st century will probably be enzymes (oxidase, hydrolase, peroxidase which present several advantages. At the same time, efforts will be made on biodegradable packaging through the use of micro-organisms able to degrade polymers. Finally, in terms of product forms, the concept of concentration might come back through the use of tablets.

  13. Science for the 21st Century


    The Federal government plays a key role in supporting the country's science infrastructure, a national treasure, and scientific research, an investment in our future. Scientific discoveries transform the way we think about our universe and ourselves, from the vastness of space to molecular-level biology. In innovations such as drugs derived through biotechnology and new communications technologies we see constant evidence of the power of science to improve lives and address national challenges. We had not yet learned to fly at the dawn of the 20th century, and could not have imagined the amazing 20th century inventions that we now take for granted. As we move into the 21st century, we eagerly anticipate new insights, discoveries, and technologies that will inspire and enrich us for many decades to come. This report presents the critical responsibilities of our Federal science enterprise and the actions taken by the Federal research agencies, through the National Science and Technology Council, to align our programs with scientific opportunity and with national needs. The many examples show how our science enterprise has responded to the President's priorities for homeland and national security, economic growth, health research, and the environment. In addition, we show how the science agencies work together to set priorities; coordinate related research programs; leverage investments to promote discovery, translate science into national benefits, and sustain the national research enterprise; and promote excellence in math and science education and work force development.

    We analyze four centuries of stock prices and dividends in the Dutch, English, and U.S. market. With the exception of the post-1945 period, the dividend-to-price ratio is stationary and predicts returns throughout all four centuries. “Excess volatility” is thus a pervasive feature of financial markets. The dividend-to-price ratio also predicts dividend growth rates in all but the most recent period. Cash-flows were therefore much more important for price movements before 1945, and the dominan...

  19. External forcing of the early 20th century Arctic warming

    Lingling Suo


    Full Text Available The observed Arctic warming during the early 20th century was comparable to present-day warming in terms of magnitude. The causes and mechanisms for the early 20th century Arctic warming are less clear and need to be better understood when considering projections of future climate change in the Arctic. The simulations using the Bergen Climate Model (BCM can reproduce the surface air temperature (SAT fluctuations in the Arctic during the 20th century reasonably well. The results presented here, based on the model simulations and observations, indicate that intensified solar radiation and a lull in volcanic activity during the 1920s–1950s can explain much of the early 20th century Arctic warming. The anthropogenic forcing could play a role in getting the timing of the peak warming correct. According to the model the local solar irradiation changes play a crucial role in driving the Arctic early 20th century warming. The SAT co-varied closely with local solar irradiation changes when natural external forcings are included in the model either alone or in combination with anthropogenic external forcings. The increased Barents Sea warm inflow and the anomalous atmosphere circulation patterns in the northern Europe and north Atlantic can also contribute to the warming. In summary, the early 20th century warming was largely externally forced.

  1. XXIst Century Ferrites

    Ferrites have always been a subject of great interest from point of view of magnetic application, since the fist compass to present date. In contrast, the scientific interest for iron based magnetic oxides decreased after Oersted discovery as they where replaced by coil as magnetizing sources. Neel discovery of ferrimagnetism boosted again interest and leads to strong developments during two decades before being of less interest. Recently, the evolution of power electronics toward higher frequency, the down sizing of ceramics microstructure to nanometer scale, the increasing price of rare-earth elements and the development of magnetocaloric materials put light again on ferrites. A review on three ferrite families is given herein: harder nanostructured Ba2+Fe12O19 magnet processed by spark plasma sintering, magnetocaloric effect associated to the spin transition reorientation of W-ferrite and low temperature spark plasma sintered Ni-Zn-Cu ferrites for high frequency power applications.

  13. 19th Century Ankara Through Historical Poems

    Özge Öztekin


    Full Text Available A city is a place whose meaning is found in the poetry created there. In Kevin Lynch’s words, a city presents the imagination with an unlimited potential for “readability”. If we consider this unlimited readability through poetry, it can be said that attempts to find the zeitgeist of a city at a certain time through literary texts must evaluate the poetry, the city and the time. This is because poetry (or literature in general, just like a city, has an important memory which oscillates through ideas of its past and future. In this sense, divan poetry and one particular example of it—historical “manzume” poems—are memories which richly illustrate the ‘continuity’ and ‘change’ within a period. This work, on 19th century Ankara, aims to evaluate the traces reflected in historical manzume poems of the time they were written. Five historical manzume poems in three texts out of seventy 19th century divan collections scanned for this work were found to be about Ankara. Two of these manzumes are by Cazib, one by Ziver Pasha, and one by Mahmud Celaleddin Pasha. The first of these is on Ankara’s dervish lodge; the second on a barracks being built in Ankara; the third on Vecihi Pasha’s governorship of Ankara; the fourth on the the Mayoral Residence. In addition to these, a manzume on the construction of Hamidiye Caddesi by Mahmud Celaleddin Pasha is discovered with in scope of the work. The aim of this work is to provide a contribution to city history through a commentary on elements of 19th century poetry concerning Ankara.

If the XIXth century tries to preserve the tradition with great accuracy the way it was transmitted from generation to generation, in the tumultuous XXth century we attend to the birth of a real industry of fashion. Some reminiscences remain, however, which gives us the opportunity to draw up a study in this regard. The present paper intends to add information regarding the folk costumes in Galati County, especially in the XIXth century. It is a short presentation of some of the most traditional clothes such as: skirt, apron, hood, shirt male and shirt female, decorative designs, footwear; without claiming to have finished the subject we intend to go on with further research.

    international solar and renewable energy professional societies, in identifying the range and level of teaching materials required for use at schools and universities. This has resulted in many new books and teaching packages involving multi media presentation materials becoming available on the open market. Availability of computer software packages, originally developed for research purposes, has led to the introduction of solar system simulation into many engineering and architectural courses. Finally, as we move into the arena of the virtual school or university of the twenty first century, there is no doubt that more and more teaching and learning material will be made available free of charge on the world wide web, and that students worldwide will eventually have ease of access to academic and commercial information on a scale unimaginable only a few years ago.

  19. The efficient presentation - obstacles, strategies, success

    Daniela-Elena Radu


    Full Text Available The making of presentations has become an omnipresent act of communication in the companies practice, but also in the didactic one. The notoriety and the increase of the importance of an efficient presentation lie in the transformations felt by a society of knowledge, communication being the answer in front of a constant information wave.Business people look in fear at the preparation of a presentation, the interaction with the audience andtheir feedback, all these leading to a low efficiency in transmitting the message.The speaker must overcome a group of obstacles, the most important being the reduced human capacityto capture the information transmitted orally; in this respect, he has available a group of visual instruments and strategies to capture the attention. In order to achieve efficiency one needs mental and emotional preparation, knowing the audience and the presentation’s objective and eliminating the old listing format in PowerPoint, for focusing the communication of the audience’s necessities. The present essay aims to analyze the verbal, non-verbal and para-verbal communication act that constitutes the base of any presentation, the reasons that lead to failure and the ways to increase efficiency, in order to succeed in transmitting a well structured and easy to remember message.Many researchers and practice workers within the communication, economic but also IT fields, have tried to find the solution for organizing and transmitting the message during a presentation, in accordance with the new technologies. In elaborating the present paper, we have used our personal experience and data obtained through 30 in-depth interviews,with managers in companies such Bostina Asociatii Skoda, Petrom etc.; we have used in our research articles of honored professors in social sciences from the Harvard and Stanford Universities , researches of the Minnesota and Ulster Universities, as well as works of specialists in marketing and information

  1. Ministerial Presentation: Holy See. Intervention of Monsignor Michael W. Banach, Permanent Representative of the Holy See to the International Atomic Energy Agency [International Ministerial Conference on Nuclear Energy in the 21. Century: Addressing Energy Needs and Environmental Challenges, Beijing (China), 20-22 April 2009

    I have the honour to deliver this Statement in the name of His Excellency Archbishop Dominique Mamberti, Secretary for the Holy See's Relations with States. At the outset, allow me to express my gratitude to the competent Authorities of the People's Republic of China, the Chinese Atomic Energy Agency and the International Atomic Energy Agency for their organization of what is developing into a most fascinating Conference. The participants in this Conference might be interested in knowing that the Holy See is a Founding Member of the International Atomic Energy Agency (IAEA). The constantly increasing world-wide demand for energy requires a serious reflection on the role of nuclear energy. The reflections that follow are offered as the Holy See's contribution, based on its specific nature, to the discussions on nuclear energy in the 21st Century. It is well known that nuclear technology presents not only risks, but also great opportunities for humanity. In this perspective, while it is important to recognize the inalienable right of States 'to develop research, production and use of nuclear energy for peaceful purposes without discrimination' (Treaty on the Non-Proliferation of Nuclear Weapons, Article IV.1), it is equally important to recognize that this right is not absolute. It is subject to the condition of an effective process of disarmament and non-proliferation of nuclear weapons. It is, above all, a right in relation to that of each other State. Each State is called to follow the ways of development and the common good of peoples and not national power, be it economic or military. A wise energy policy necessarily leads to the development of peoples - a development that is respectful of the natural environment, as a good in itself and as a good from which life and human health also depend, and ever mindful of the most disadvantaged populations (Pope Benedict XVI, Angelus Address, July 29, 2007). As affirmed by the United Nations Declaration on the Right to

  2. History of twentieth-century physics

    Kapitza, Sergei P


    The meaning and message of the history of science will be discussed with relevance to XX century physics. This decisive period began in 1894-95 with the discoveries of the electron,X-rays and radioactivity,with the consequent development of relativity and quantumphysics. Connections of the development of science and society in XX century with culture and the influence on industry will be examined. Finally, the corruption of physics by the military will be considered. The influence of physics on chemistry and biology will be briefly treated and the impact of the approach and method of physics on modern thinking will be assessed. It should be kept in mind that the history of science is not a way of getting a simplified or adulterated presentation of the subject ,in this case of physics and so some understanding of general physics will be assumed. On the other hand, the broader generalisations of the history of ideas and events are illustrated (if not proven) by the facts (and myths) of science. Finally,as an e...

  3. Nineteenth-Century Anglo-Irish Cervantine

    Asier Altuna-García de Salazar


    Full Text Available To commemorate the fourth centenary of the publication of the first part of the Spanish masterpiece of all times Don Quixote by Miguel de Cervantes, this article approaches in an introductory manner some of the literary productions which sprang from Cervantes’s original within the Irish context. In the case of Ireland the Cervantine inspiration, albeit minor and neglected, has also been present; and, it is most probably the nineteenth century which provides the most ample and varied response to Cervantes’s masterpiece in many a different way. Our aim is to see briefly how the legacy of Don Quixote found distinct expression on the Emerald Isle. Indeed, all these Cervantine contributions from Ireland during the nineteenth century were also deeply imbued with the politics of literature and society in a country which experienced historical, social and cultural turmoil. The reference to Cervantes as a key writer in Spanish letters will not only be reduced to his masterpiece of all times; but, will also be tackled in critical pieces of importance in Ireland.

  6. Ubiquitous Presenter: A Tablet PC-based System to Support Instructors and Students

    Price, Edward; Simon, Beth


    Digital lecturing systems (computer and projector, often with PowerPoint) offer physics instructors the ability to incorporate graphics and the power to share and reuse materials. But these systems do a poor job of supporting interaction in the classroom. For instance, with digital presentation systems, instructors have limited ability to spontaneously respond to student questions. This limitation is especially acute during classroom activities such as problem solving, Peer Instruction, and Interactive Lecture Demonstrations (ILDs).2 A Tablet PC, a laptop computer with a stylus that can be used to "write" on the screen, provides a way for instructors to add digital ink spontaneously to a presentation in progress. The Tablet PC can be a powerful tool for teaching,3,4 especially when combined with software systems specifically designed to leverage digital ink for pedagogical uses. Ubiquitous Presenter (UP) is one such freely available system.5 Developed at the University of California, San Diego, and based on Classroom Presenter,6 UP allows the instructor to ink prepared digital material (such as exported PowerPoint slides) in real time in class. Ink is automatically archived stroke by stroke and can be reviewed through a web browser (by both students and instructors). The system also supports spontaneous in-class interaction through a web interface—students with web-enabled devices (Tablet PCs, regular laptops, PDAs, and cell phones) can make text-, ink-, or image-based submissions on the instructor's slides. The instructor can review and then project submitted slides to the class and add additional ink, so that material generated by students can be a focus for discussion. A brief video showing UP in action is at In this article, we describe UP and give examples of how UP can support the physics classroom.

  8. Engaging the audience: developing presentation skills in science students.

    Stuart, Ann E


    This article describes a graduate class in presentation skills ("PClass") as a model for how a class with similar objectives, expectations and culture might be mounted for undergraduates. The required class is given for students in neuroscience and physiology programs at the University of North Carolina at Chapel Hill; I describe the class in the years I led it, from 2003-2012. The class structure centered on peer rehearsal, critiquing of PowerPoint, and chalk talks by the students; video-recording of student talks for later review by the student with the instructor; and presentation of polished talks in a formal setting. A different faculty visitor to the class each week gave the students a variety of perspectives. The students also gained insight into their own evolving skills by discussing the strengths and weaknesses of seminars given by visitors to the campus. A unique feature of the class was collaboration with a professional actor from the University's Department of Dramatic Arts, who helped the students develop techniques for keeping the attention of an audience, for speaking with confidence, and for controlling nervousness. The undergraduate campus would be expected to lend itself to this sort of interdisciplinary faculty cooperation. In addition, students worked on becoming adept at designing and presenting posters, introducing speakers graciously and taking charge of the speaker's question session, and speaking to a lay audience.

    Full Text Available Review of: Arupjyoti Saikia. 2013. A Century of Protests: Peasant Politics in Assam Since 1900. New Delhi and Abingdon: Routledge. Notwithstanding its somewhat misleading subtitle, A Century of Protests is a painstaking reconstruction of the checkered agrarian history of the Brahmaputra Valley between the passage of the Assam Land Revenue Regulation of 1886 and the repeal of the Assam Tenancy Act of 1971 in 1986. The state of Assam in India today, bordering what is now Bangladesh, lies beneath the watchful eyes of the Eastern Himalayas, through which the mighty Brahmaputra gushes and breathes life into the valley. The landscape of the Brahmaputra Valley, historically speaking, has been as much a patchwork of field and forest as of different ethnolinguistic and religious groups, ever fluid and shifting in response to human and non-human vectors of change. The contested relations of power that yoke together owners and cultivators of this complex, variegated landscape in the late colonial and early postcolonial eras is the subject of the book under review.

  19. Indoor climate in the 21th century

    Field studies have shown that in many buildings there are people who are annoyed by poor indoor climate even if the buildings satisfy all standards and guidelines. This is because the present requirements are quite mild. A shift of paradigm is foreseen to take place in the 21th century - from a mediocre to an excellent indoor climate. The article proposes five principles as elements of a new philosophy about the optimum indoor climate: (1) Improved indoor air quality increases productivity and decreases sick building syndrome symptoms, (2) Unnecessary indoor pollution sources should be avoided, (3) The air should be served cool and dry to the occupants, (4) Personalized air, that is, a small amount of clean air, should be served gently, close to the breathing zone of each person, (5) Individual control of the thermal environment should be provided. The principles are compatible with energy efficiency and sustainability

  20. Neutron Physics Entering the XXI Century

    Aksenov, V L


    The objectives of present-day neutron physics are neutron-aided investigations of fundamental interactions and symmetries, high excited states of nuclei, crystalline and magnetic structures, dynamic excitations in solids and liquids over a wide range of energies. The state-of-art and perspectives of the solution of most topical and principle problems of neutron physics are analyzed. The main conclusion is that neutron physics provides rich information for nuclear particle physics, physics of nucleus, condensed matter physics, chemistry, biology, materials science, and earth sciences. In the next century, however, new higher flux neutron sources must be created. By the year 2010 the number of nuclear reactors used for physical research will reduce to 10-15 reactors over the world. Trends in the development of neutron sources are analyzed. The possibilities of leading neutron research centers in the world are considered and most promising projects of neutron sources are discussed.

  1. A century of the edgewise appliance

    James L Vaden


    Full Text Available The edgewise appliance, born in the mind of Dr. Edward Angle and first introduced on June 2, 1925, has withstood the test of almost a century of time and usage. The 022 standard appliance that Angle described in a series of four articles in Dental Cosmos is being used by many orthodontic clinicians in fundamentally the same form as it was presented in 1928 and 1929 in Dental Cosmos. Yes, it has been modified in innumerable ways. However, to use one of the modifications, the clinician must understand and respect the fundamentals of its use. This treatise describes the appliance′s evolution from Angle to its use today. The force system of today is simpler and more refined than what Angle envisioned but the appliance is "intact." It is as modern as tomorrow and will continue to be used as long as the specialty exists. It was Angle′s greatest contribution.

    A quarter century ago, Jan van Paradijs and I started on a scientific journey, our lives became entwined, and a friendship evolved that shaped both our lives scientifically and in personal matters. To tell our story was very difficult for me. I went through 24 years of notes in my calendars and re-lived more than 8000 days of my own and Jan's life, 20 years of slides, 15 years of e-mail. There were times that I had to stop and leave it alone for a week or more as it became too emotional. Few people know (perhaps only two) what we meant for each other. When Jan died, part of me died.

  5. Northern Hemisphere hydroclimate variability over the past twelve centuries.

    Ljungqvist, Fredrik Charpentier; Krusic, Paul J; Sundqvist, Hanna S; Zorita, Eduardo; Brattström, Gudrun; Frank, David


    Accurate modelling and prediction of the local to continental-scale hydroclimate response to global warming is essential given the strong impact of hydroclimate on ecosystem functioning, crop yields, water resources, and economic security. However, uncertainty in hydroclimate projections remains large, in part due to the short length of instrumental measurements available with which to assess climate models. Here we present a spatial reconstruction of hydroclimate variability over the past twelve centuries across the Northern Hemisphere derived from a network of 196 at least millennium-long proxy records. We use this reconstruction to place recent hydrological changes and future precipitation scenarios in a long-term context of spatially resolved and temporally persistent hydroclimate patterns. We find a larger percentage of land area with relatively wetter conditions in the ninth to eleventh and the twentieth centuries, whereas drier conditions are more widespread between the twelfth and nineteenth centuries. Our reconstruction reveals that prominent seesaw patterns of alternating moisture regimes observed in instrumental data across the Mediterranean, western USA, and China have operated consistently over the past twelve centuries. Using an updated compilation of 128 temperature proxy records, we assess the relationship between the reconstructed centennial-scale Northern Hemisphere hydroclimate and temperature variability. Even though dry and wet conditions occurred over extensive areas under both warm and cold climate regimes, a statistically significant co-variability of hydroclimate and temperature is evident for particular regions. We compare the reconstructed hydroclimate anomalies with coupled atmosphere-ocean general circulation model simulations and find reasonable agreement during pre-industrial times. However, the intensification of the twentieth-century-mean hydroclimate anomalies in the simulations, as compared to previous centuries, is not supported

    The drought problem always exists somewhere in the world so that the economy of some nation or nations is always being adversely influenced by this factor. Although drought is a natural component of the climate in arid and semi-arid areas, it can occur in areas, which normally receive adequate precipitation. Available hydro meteorological data indicate droughts have occurred through the last century in Bulgaria and they a part of the climatic cycle on the Balkan Peninsula. The precipitation distribution is one of the basic characteristics of the drought occurrence in a given region. However, the distributions of additional meteorological elements should be also taken into account in order to describe the degree of the climate dryness. For example, the distribution of air temperature is an especially important characteristic for drought classifications. The last years in Bulgaria were drier and warmer than the normals for the period of so-called 'current climate' (1961-1990). Precipitation was approximately 80-85 % less than the normals. Statistical methods were used in order to analyze the long-term variations of precipitation, air temperature. The long-term series of data were smoothed by averages and they were also approximated by means of a polynomial. These methods eliminate the random and short periodical fluctuations of the time series. The Spearman coefficient (r) and the Kendall coefficient (rl) were used in order to investigate the existence of eventual trends. Some quantitative criteria were also used for a comparison of the drought frequency and intensity between different regions and years. As a result of the conducted analysis, the investigated period can be divided to separate sub-periods with duration of 10-15 years. These years are characterized with different moisture conditions. Three periods can be determined during the 20 th century, which are characterized by longer and severe droughts, namely 1902-1913, 1942-1953 and 1982-1994. The drought

  19. Climate Change: Past, Present, and Future

    Chapman, David S.; Davis, Michael G.


    Questions about global warming concern climate scientists and the general public alike. Specifically, what are the reliable surface temperature reconstructions over the past few centuries? And what are the best predictions of global temperature change the Earth might expect for the next century? Recent publications [National Research Council (NRC), 2006; Intergovernmental Panel on Climate Change (IPCC), 2007] permit these questions to be answered in a single informative illustration by assembling temperature reconstructions of the past thousand years with predictions for the next century. The result, shown in Figure 1, illustrates present and future warming in the context of natural variations in the past [see also Oldfield and Alverson, 2003]. To quote a Chinese proverb, “A picture's meaning can express ten thousand words.” Because it succinctly captures past inferences and future projections of climate, the illustration should be of interest to scientists, educators, policy makers, and the public.

  20. Medicine in 21st Century



    An ancient Chinese theme of "Shen Nong tasted hundred herbs and confronted seventy toxicities a day" means generally that medicine was created by the ancient labor people, although there's no trace of the real Shen Nong. Accordingly some animals would take certain herbs for stopping traumatic bleeding just as our ancestors done. Medicine iniated a long time ago but the development of modern medicine is really a little bit more than hundred years, Pasteur discovered bacteria and reported in 1857, not yet 150 years from now. Virchow discovered cell cleavage and thus founded modern basic cellular pathology somewhat a year later than the former. Mendels bean test opened a new era for genetic research and concluded in 1863. Roentgen discovered X-ray in 1895 and We've celebrated the 100th anniversary of the X-ray discovery several years ago. The earliest application of penicillin was in 1940, not yet 60 years ago. The medicine possesses a jumping development during the recent half century in association with the advancement of synthetic chemistry, electronic and bioscientific technolgy.

  1. Attempts to Save Tragedy in the 19th Century

    Alicja Przybyszewska


    Full Text Available The article outlines the issue of genre-transformation of tragedy in 19th-century Polish drama. The fundamental question is tragedy’s potential after liberation from the most important structural categories of the genre: the three unities, catharsis and anagnorisis. The discussion on the 19th-century patterns of tragedy, derived from contemporary theory, criticism, and theatrical production, are based on research by Marek Dybizbański, who presented an interesting analysis of the problem, which was an important indicator of contemporary literary thought, in his study called Tragedia polska drugiej połowy XIX wieku — wzorce i odstępstwa [The Polish Tragic Drama in Late 19th Century — Patterns and Divergence]. The issues discussed were: disproportion between expectations and effects, indicated by repertoires and contemporary debate on drama, lack of standard productions of tragedy, matched by great surplus of texts that tried to set the standard, and by programmatic declarations on how to do it. The author, following Dybizbański’s discussion, focuses on the question why the 19th century in Poland was, for tragedy, a lost time.

  2. Compassionate Play in The Ludic Century

    James Dyer


    Full Text Available In 2013 game designer Eric Zimmerman wrote a provocative manifesto entitled ‘Manifesto for a Ludic Century’ (2013a, in which Zimmerman declares the 21st Century’s dominant cultural form to be games. Consequently, Zimmerman proposes that the individual occupant of the century is therefore in a continuous state of game engagement. As such, this re-contextualisation of game space and play, indefinitely articulates the individual as a constant player and character, and thusly challenges the notions of selfhood. Importantly it should be noted, the state of a ludic century is explicitly assumed as a truth, however superficial it may appear. Accordingly, this paper is then afforded to be an extended hypothesis of the proposed ludic century, rather than a critical dissection and response to Zimmerman’s manifesto. This enables a hermeneutic framing of the questions: ‘What does it mean to live in a ludic century?’and ‘in what capacity may the self exist in the ludic century?’ These questions will attempt to distinguish play as an inherent cultural logic that extends beyond the limitations of explicit ‘gamification’ or instrumental play (Stenros et al., 2009; Zichermann, 2010. Concluding, it is claimed that the ludic century elicits a sustained delusion of self, as the player is confined to the designed game structure, which inhibits authentic engagement and interaction with environment and self. It is proposed that this evokes a form of suffering, the compassionate play within the ludic century.

    Saeed Ketabi


    Full Text Available Pronunciation, despite being known as an important component of language learning, has not been awarded due attention within the field of language education. This article is a humble attempt to present an overview of the history of pronunciation teaching. Different approaches and methods of language teaching from the late nineteenth century into the new millennium are reviewed and discussed with regard to their stance in pronunciation instruction. Recent trends and issues of pronunciation teaching, e.g. intelligibility and Lingua Franca Core are also highlighted. Discussions like the present one might be beneficial in gaining a better understanding and evaluation of the status quo in order to improve and enhance the status of pronunciation instruction within language pedagogy.Keywords: Pronunciation instruction, Teaching methods, Intelligibility, Lingua Franca Core

  8. The global nitrogen cycle: Past, present and future

    James N. Galloway


    Food and energy production converts N2 to reactive N species that cascade through environmental reservoirs and in the process impact human and ecosystem health. This presentation will examine the impact of increased N mobilization on the global N cycle by contrasting N distribution in the late-19th century with those of the late-20th century. The presentation will give a general overview of regional differences and will conclude with a projection of the global N cycle for 2050.

  9. Projecting twenty-first century regional sea-level changes

    A. B. A. Slangen; Carson, M; Katsman, C.A.; Wal, R.S.W. van de; Köhl, A.; Vermeersen, L.L.A.; Stammer, D.


    We present regional sea-level projections and associated uncertainty estimates for the end of the 21 (st) century. We show regional projections of sea-level change resulting from changing ocean circulation, increased heat uptake and atmospheric pressure in CMIP5 climate models. These are combined with model- and observation-based regional contributions of land ice, groundwater depletion and glacial isostatic adjustment, including gravitational effects due to mass redistribution. A moderate an...

  10. Models of Utopia: Representations of Nineteenth-Century Paris

    Stone, Shiloh Joseph


    In the texts analyzed in this thesis, nineteenth-century Paris illustrates the utopian principles formulated by Karl Mannheim whose conceptualizations concern the social and moral order that makes up human existence. His utopia is characterized by human thoughts, behaviors, and actions. In our analysis of the works by Charles Fourier, Victor Hugo, and Emile Zola, common themes emerge as each writer undertakes the task of representing the past, present, and future Paris. They describe ideas of...
