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

    International Nuclear Information System (INIS)

    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

    Full Text Available This paper discusses importance of technology education and evidence of declining performance of junior secondary school students in basic technology subject. 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.

    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.

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.

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

    Directory of Open Access Journals (Sweden)

    Lachenmeier Dirk W

    2006-05-01

    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.

    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

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

    Science.gov (United States)

    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

    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.

    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

    Full Text Available The presentation program PowerPoint is probably the most used tool in the schools, high schools and universities of today. 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. The program carries an inherent tendency to crate fragmentation of thought and cognitive overload. In order to avoid this we should stop thinking in terms of technology and begin to think rhetorically. What we need is media rhetoracy: the ability to communicate persuasively and appropriately.

    2000-07-01

    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

    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

    Directory of Open Access Journals (Sweden)

    Beth Pateman, HSD, MPH

    2006-03-01

    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.

    Galabov, Vasko

    2015-01-01

    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

    Science.gov (United States)

    Moore, Sandra K.; Gast, Matthew A.

    2009-01-01

    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

    International Nuclear Information System (INIS)

    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.

    2016-05-01

    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

    International Nuclear Information System (INIS)

    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.

    2011-01-01

    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...

    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

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.

    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

    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)

    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

    International Nuclear Information System (INIS)

    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

    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

    2004-12-01

    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.

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

    2014-12-01

    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

    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

    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

    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.

    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. Therefore, the low energy consumption per capita at present will see a rapid and constant increase in demand in the near future. As such, great importance is attached to

    International Nuclear Information System (INIS)

    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.)

  20. The management century.

    Science.gov (United States)

    Kiechel, Walter

    2012-11-01

    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

    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

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

    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

    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

    CERN Document Server

    2015-01-01

    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.

    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

    International Nuclear Information System (INIS)

    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

    2006-12-01

    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

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...

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.

    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

    CERN Document Server

    Alley, Michael

    2013-01-01

    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...

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.

    2004-07-01

    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.

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

    2013-12-01

    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

    International Nuclear Information System (INIS)

    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

    Directory of Open Access Journals (Sweden)

    Özge Öztekin

    2015-12-01

    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.

    Full Text Available Nowadays we attach a great importance to the clothes we wear from the moment we buy or make them, to the moment we decide if they are appropriate with our personal style, the place where we wear them or when we use them. 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.

    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.

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

    International Nuclear Information System (INIS)

    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).

    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

    2005-03-01

    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.

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 http://physics.csusm.edu/UP. In this article, we describe UP and give examples of how UP can support the physics classroom.

    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

    International Nuclear Information System (INIS)

    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

    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

    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.

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

    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

  17. Drought periods during XXth century

    International Nuclear Information System (INIS)

    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

    2010-09-01

    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.

    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.

    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

    Directory of Open Access Journals (Sweden)

    James Dyer

    2014-11-01

    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.

    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

  3. Revolution, Romanticism and the Long Nineteenth Century

    Directory of Open Access Journals (Sweden)

    Adriana Craciun

    2006-04-01

    Full Text Available In order to consider the future of Victorian literary studies within the long nineteenth century, we must go back to that earlier “period” of the nineteenth century, and the French Revolution of 1789. Drawing on the aesthetic and political innovations of 1790s women's writings, this essay argues that we need to reconceive of nineteenth-century literary studies beyond the period boundaries of Romantic and Victorian. The sexualization of revolutionary Terror, and particularly of Robespierre, in Romantic-era writings by women like Helen Maria Williams, Mary Robinson and Fanny Burney, offers surprising precedents for the feminization of Terror associated with the retrospectives of Victorian writers like Carlyle and Dickens. In this respect, and given many other aesthetic continuities (for example, the crossgender and cross-period appeal of the “poetess” figure, the “Victorian period” appears increasingly unsatisfactory when compared to the merits of a long nineteenth-century model for literary studies.

  10. The Nineteenth-Century Revolution in Astronomy

    Science.gov (United States)

    Batten, Alan Henry

    2015-08-01

    The term "revolution" in scientific contexts usually refers either to the beginnings of modern western science in the sixteenth and seventeenth centuries, or to the two great revolutions of early twentieth century physics. Comparison of what was known at the beginning of the nineteenth century with what was known at the end, however, shows that century to have been one of transformation in astronomy, and in the other sciences, that amounts to "revolution". Astronomers in 1800 knew neither the nature of the Sun nor the distances of the stars. Developments in instrumentation enabled the first determinations of stellar parallax in the 1830s, and later enabled the solar prominences to be studied outside the brief momemnts of total eclipses. The development of photography and of spectroscopy led to the birth of observational astrophysics, while the greater understanding of the nature of heat and the rise of thermodynamics made possible the first attempts to investigate the theory of stellar structure. Nothing was known in 1800 of extra-galactic objects apart from some tentative identifcations by William Herschel but, by the end of the century, the discovery of the spiral structure of some nebulae had led some to believe that these were the "island universes" about which Kant had speculated. Of course, astrophysics and cosmology would be much further developed in the twentieth century and those of us whose careers spanned the second half of that century look back on it as a "golden age" for astronomy; but the nineteenth century was undoubtedly a time of rapid transformation and can be reasonably described as as one of the periods of revolution in astronomy.

  11. Cold fusion labeled fiasco of century

    International Nuclear Information System (INIS)

    The gamble of researchers B. Stanley Pons and Martin Fleischmann to go public with their announcement of excess power from nuclear fusion at room temperature before they had solid evidence of fusion products is the scientific fiasco of the century, charges John R. Huizenga of the University of Rochester. He describes the claims of Pons and Fleischmann as a delusion and as pathological science. It would require belief in miracle after miracle for one to accept their discovery, he charges. Huizenga criticizes the researchers on several counts: they failed to challenge their own findings with control experiments and presentations to colleagues; they rushed to publication with unchecked and inaccurate data; they chose an unconventional method, a public press conference, to release scientific findings; their claims were not easily reproduced by others; and they lobbied Congress for funds before their claims were confirmed by independent researchers. Cold fusion producing excess power is an example of bad science where the normal rules and procedures of the scientific process were violated, Huizenga says

    Full Text Available The Asian Century is rich and already 14 years old. Today, Asia is in the middle of a historic transformation which has brought both challenges and opportunities. To meet these challenges, Asian leaders need to devise bold and innovative national policies for pursuing avenues for regional and global cooperation. In the similar way organisation and business in Asia will transform. This transformative whirlpool calls the Asian private sector and public sector organisations for absorption of new wisdom, values and principles in place of 20th century’s management. Overall, the capacity to respond to the changing global economic landscape through flexibility and adaptivness will carry a high premium. This paper delve the issues how Asian Organisations have already been used the wisdom during the global chaos. Deriving from the examples of Asia in the midst of global chaos in many points of time, this present paper attempts to re-focus on organisational wisdom of commitment and ability for Asian organisation, modernization, governance and helping to retool institutions, for enhancing transparency, and finally to develop accountability for organisational resilience and survival.

  13. How 21st century droughts affect food and environmental security

    Science.gov (United States)

    Kogan, Felix

    The first 13th years of the 21st century has begun with a series of widespread, long and intensive droughts around the world. Extreme and severe-to-extreme intensity droughts covered 2-6% and 7-16% of the world land, respectively, affecting environment, economies and humans. These droughts reduced agricultural production, leading to food shortages, human health deterioration, poverty, regional disturbances, population migration and death. This presentation is a travelogue of the 21st century global and regional droughts during the warmest years of the past 100 years. These droughts were identified and monitored with the NOAA operational space technology, called Vegetation Health (VH), which has the longest period of observation and provide good data quality. The VH method was used for assessment of vegetation condition or health, including drought early detection and monitoring. The VH method is based on operational satellites data estimating both land surface greenness (NDVI) and thermal conditions. The 21st century droughts in the USA, Russia, Australia Argentina, Brazil, China, India and other principal grain producing countries were intensive, long, covered large areas and caused huge losses in agricultural production, which affected food and environmental security and led to food riots in some countries. This presentation investigate how droughts affect food and environmental security, if they can be detected earlier, how to monitor their area, intensity, duration and impacts and also their dynamics during the climate warming era with satellite-based vegetation health technology.

    21st Century Kinematics focuses on algebraic problems in the analysis and synthesis of mechanisms and robots, compliant mechanisms, cable-driven systems and protein kinematics. The specialist contributors provide the background for a series of presentations at the 2012 NSF Workshop. The text shows how the analysis and design of innovative mechanical systems yield increasingly complex systems of polynomials, characteristic of those systems. In doing so, takes advantage of increasingly sophisticated computational tools developed for numerical algebraic geometry and demonstrates the now routine derivation of polynomial systems dwarfing the landmark problems of even the recent past. The 21st Century Kinematics workshop echoes the NSF-supported 1963 Yale Mechanisms Teachers Conference that taught a generation of university educators the fundamental principles of kinematic theory. As such these proceedings will be provide admirable supporting theory for a graduate course in modern kinematics and should be of consid...

    2005-01-01

    Pulmonary tuberculosis took on alarming proportions in the 18th-century Europe. This study examines the ways learned medical practitioners presented the causes of the malady in Great Britain and France, by analyzing 12 medical treatises. Four etiological models appears to have dominated medical thinking in this context: theories that emphasize contagion; those which attribute the cause to physiological disorders; those which find the origin in hereditary predispositions; and those theories which observe a link with behaviour and lifestyles. The study also shows how one of these theories - the hereditary theory - eventually triumphed over the others and became the dominant for the better part of the 19th century, and will be examined within the context of the growth of liberal and individualist ideology.

    The generation and management of wastes has become one of the most pressing problems facing modern society. Though often depicted as a problem of a technical and environmental management nature, many aspects of the issue can be framed is sociological terms. This paper attempts to track the path of social perceptions of, and response to, wastes in western democracies from the turn of the century until the present day, and concludes by offering some ideas as to how perceptions and the consequent demands for information and involvement in decision-making on waste management may develop as we move into the 21. century. The focus of the paper is non-radioactive wastes, however, there is considerable overlap and commonalty with social responses to nuclear wastes. (authors)

    Full Text Available Information and communication technologies will undoubtely be leading determinants of urban landscape in the 21st century. Until the present day, it was assumed that urban landscapes were being shaped by conventional factors such as demography, social and economical structure, transportion, infrastructure, building technologies etc. In spite of many speculative approaches, recent developments in information and communication technologies can offer us some clues which may go beyond mere speculation. The“intelligent city” which is based on “autonomous” and “intelligent” objects and agents promising novel solutions to urban problems. Mobile communication is also another promising domain to offer creative solutions to some cronical urban problems. All these novelties provide sufficient reasons to think about new urban structures based upon information technologies.This paper is an attempt to discuss probable effects of information technologies, as new dynamics to shape the urban environment and urban life of the 21st century.

  19. The environmental history of cetaceans in Portugal: ten centuries of whale and dolphin records.

    Directory of Open Access Journals (Sweden)

    Cristina Brito

    Full Text Available The history between cetaceans and humans is documented throughout time not only in reports, descriptions, and tales but also in legal documents, laws and regulations, and tithes. This wealth of information comes from the easy spotting and identification of individuals due to their large size, surface breathing, and conspicuous above water behaviour. This work is based on historical sources and accounts accounting for cetacean presence for the period between the 12th and 17th centuries, as well as scientific articles, newspapers, illustrations, maps, non-published scientific reports, and other grey literature from the 18th century onwards. Information on whale use in Portugal's mainland has been found since as early as the 12th century and has continued to be created throughout time. No certainty can be given for medieval and earlier events, but both scavenging of stranded whales or use of captured ones may have happened. There is an increasing number of accounts of sighted, stranded, used, or captured cetaceans throughout centuries which is clearly associated with a growing effort towards the study of these animals. Scientific Latin species denominations only started to be registered from the 18th century onwards, as a consequence of the evolution of natural sciences in Portugal and increasing interest from zoologists. After the 19th century, a larger number of observations were recorded, and from the 20th century to the present day, regular scientific records have been collected. Research on the environmental history of cetaceans in Portugal shows a several-centuries-old exploitation of whales and dolphins, as resources mainly for human consumption, followed in later centuries by descriptions of natural history documenting strandings and at sea encounters. Most cetaceans species currently thought to be present in Portuguese mainland waters were at some point historically recorded.

  20. 21st century's energy: hydrogen energy system

    International Nuclear Information System (INIS)

    Fossil fuels (i.e., petroleum, natural gas and coal), which meet most of the world's energy demand today, are being depleted fast. Also, their combustion products are causing the global problems, such as the greenhouse effect, ozone layer depletion, acid rains and pollution, which are posing great danger for our environment and eventually for the life in our planet. Many engineers and scientists agree that the solution to these global problems would be to replace the existing fossil fuel system by the Hydrogen Energy System. Hydrogen is a very efficient and clean fuel. Its combustion will produce no greenhouse gases, no ozone layer depleting chemicals, little or no acid rain ingredients and pollution. Hydrogen, produced from renewable energy (e.g., solar) sources, would result in a permanent energy system, which we would never have to change. However, there are other energy systems proposed for the post-petroleum era, such as a synthetic fossil fuel system. In this system, synthetic gasoline and synthetic natural gas will be produced using abundant deposits of coal. In a way, this will ensure the continuation of the present fossil fuel system. The two possible energy systems for the post-fossil fuel era (i.e., the solar hydrogen energy system and the synthetic fossil fuel system) are compared with the present fossil fuel system by taking into consideration production costs, environmental damages and utilization efficiencies. The results indicate that the solar hydrogen energy system is the best energy system to ascertain a sustainable future, and it should replace the fossil fuel system before the end of the 21st Century

    2011-12-01

    (Great Salt Lake, Searles Lake), geothermal systems (Salton Sea) and oil fields contain lithium, but in low concentrations that add relatively little to estimated global resources. Igneous deposits, which constitute 26% of estimated global resources, consist largely of pegmatites, including past and present producers at Kings Mountain-Bessemer City (USA), Greenbushes (Australia) and Bikita (Zimbabwe), as well as numerous active prospects, especially in Canada and China. Amenability of these deposits to economic extraction is controlled by mineralogy and zoning of lithium, which vary considerably from deposit to deposit. An additional 8% of global lithium resources is estimated to be present in unusual deposits including largely hectorite clays in volcaniclastic rocks at Kings Valley (USA) and jadarite in lacustrine evaporite deposits (Serbia), which present new challenges to both mining and processing. If this highly varied population of deposits can be converted to reserves, lithium supplies for the 21st century EV market are relatively secure.

  10. Energy, environment, and sustainable development in the new century

    International Nuclear Information System (INIS)

    The new century's ultimate global challenge will be for the world community to sustain its growth while preserving environment in the presence of ever increasing world population, that is, balancing economy, environment, and population problems. The sheer magnitude of population growth, together with people's innate aspirations for improved life, will put enormous demands on energy production. Deployment of new, energy-intensive technologies will further increase the pressure. The increased energy production and consumption in turn will inevitably impact on our global environment, as exemplified by such issues as global climate change. Environmental issues associated with energy production and use are affecting society's preferences for different types of energy. Thus, energy and environment will remain two poles of a central global issue in this century. The challenge is then how to produce energy in a way that is friendly to environment. The combination of nuclear power and various renewable energy sources may offer a key component to meeting the challenge. This paper presents a big picture of globally sustainable development in the new century. The role of energy and environment is brought to the fore in this context. In particular, it addresses the importance of nuclear power and renewable energy, as this combination of options will absolutely minimize the emission of greenhouse gases that have steadily and alarmingly degraded our atmospheric environment.

    Glaciers are ablating rapidly the world over. Nowhere are the rates of retreat and downwasting greater than in the Hindu Kush-Himalaya (HKH) region. It is estimated that over the next century, 40,000 square kilometers of present glacier area in the HKH region will become ice free. Most of this area is in major valleys and the lowest glaciated mountain passes. The existence and characteristics of glaciers have security impacts, and rapidly changing HKH glaciers have broad strategic implications: (1) Glaciers supply much of the fresh water and hydroelectric power in South and Central Asia, and so glaciers are valuable resources. (2) Shared economic interests in water, hydroelectricity, flood hazards, and habitat preservation are a force for common cause and reasoned international relations. (3) Glaciers and their high mountains generally pose a natural barrier tending to isolate people. Historically, they have hindered trade and intercultural exchanges and have protected against aggression. This has further promoted an independent spirit of the region's many ethnic groups. (4) Although glaciers are generally incompatible with human development and habitation, many of the HKH region's glaciers and their mountains have become sanctuaries and transit routes for militants. Siachen Glacier in Kashmir has for 17 years been "the world's highest battlefield," with tens of thousands of troops deployed on both sides of the India/Pakistan line of control. In 1999, that conflict threatened to trigger all-out warfare, and perhaps nuclear warfare. Other recent terrorist and military action has taken place on glaciers in Kyrgyzstan and Tajikistan. As terrorists are forced from easily controlled territories, many may tend to migrate toward the highest ground, where definitive encounters may take place in severe alpine glacial environments. This should be a major concern in Nepali security planning, where an Army offensive is attempting to reign in an increasingly robust and brutal

    2003-08-01

    Toward the end of the twentieth century, it became evident to professionals working within the meterological arena that the world's climate system was showing signs of change that could not be adequately explained in terms of natural variation. Since that time there has been an increasing recognition that the climate system is changing as a result of human industries and lifestyles, and that the outcomes may prove catastrophic to the world's escalating population. Compiled by an international team formed under the auspices of the World Meteorological Organization (WMO), Climate: Into the 21st Century features an unrivalled collection of essays by the world's leading meteorological experts. These fully integrated contributions provide a perspective of the global climate system across the twentieth century, and describe some of the most arresting and extreme climatic events and their effects that have occurred during that time. In addition, the book traces the development of our capabilities to observe and monitor the climate system, and outlines our understanding of the predictability of climate on time-scales of months and longer. It concludes with a summary of the prospects for applying the twentieth century climate experience in order to benefit society in the twenty-first century. Lavishly illustrated in color, Climate is an accessible acccount of the challenges that climate poses at the start of the twenty-first century. Filled with fascinating facts and diagrams, it is written for a wide audience and will captivate the general reader interested in climate issues, and will be a valuable teaching resource. William Burroughs is a successful science author of books on climate, including Weather (Time Life, 2000), and Climate Change: A Multidisciplinary Approach (2001), Does the Weather Really Matter? (1997) and The Climate Revealed (1999), all published by Cambridge University Press.

  17. The role of nuclear science and engineering in the twenty first century

    International Nuclear Information System (INIS)

    For the sustainable development of the world and the welfare of mankind in the 21st century, nuclear energy and radiation including particle and photon beams must play an important role, although there is a large negative side in them. As in the 20th century, the activities of both research and education in Nuclear Science and Engineering (NSE) should be positively promoted and enhanced for safer nuclear energy and wider utilization of radiation and various beams and for the diminishment of their negative side. In this paper, a brief history of NSE in the 20th century and its implications are given first. As an example, the NSE activity in the 100 years' history of Kyoto University is shown. And then the 40 years' development of NSE in Japan is briefly introduced. Finally, presented is the way that the research and education in NSE in the 21st century should be. (author)

    Full Text Available In the paper the results of many years of archival and field investigations in the history of bauxite mining of the three authors are presented. It was established that in Istria in the valley of the river Mirna beneath the Castle of Sovinjak bauxite was exploited already 400 years ago, and that 1808 about this ore the first scientific account was published. Accordingly, the statements in the professional literature that the first bauxite mine opened 1873 in the French Provence and that the bauxite ore for the first time was scientifically described 1821 have to be revised. About this necessary revision here the essential proofs are produced.

    The U.S. Geological Survey has created a geochemical database of geologic material samples collected in Alaska. This database is readily accessible to anyone with access to the Internet. Designed as a tool for mineral or environmental assessment, land management, or mineral exploration, the initial version of the Alaska Geochemical Database - U.S. Geological Survey Data Series 637 - contains geochemical, geologic, and geospatial data for 264,158 samples collected from 1962-2009: 108,909 rock samples; 92,701 sediment samples; 48,209 heavy-mineral-concentrate samples; 6,869 soil samples; and 7,470 mineral samples. In addition, the Alaska Geochemical Database contains mineralogic data for 18,138 nonmagnetic-fraction heavy mineral concentrates, making it the first U.S. Geological Survey database of this scope that contains both geochemical and mineralogic data. Examples from the Alaska Range will illustrate potential uses of the Alaska Geochemical Database in mineral exploration. Data from the Alaska Geochemical Database have been extensively checked for accuracy of sample media description, sample site location, and analytical method using U.S. Geological Survey sample-submittal archives and U.S. Geological Survey publications (plus field notebooks and sample site compilation base maps from the Alaska Technical Data Unit in Anchorage, Alaska). The database is also the repository for nearly all previously released U.S. Geological Survey Alaska geochemical datasets. Although the Alaska Geochemical Database is a fully relational database in Microsoft® Access 2003 and 2010 formats, these same data are also provided as a series of spreadsheet files in Microsoft® Excel 2003 and 2010 formats, and as ASCII text files. A DVD version of the Alaska Geochemical Database was released in October 2011, as U.S. Geological Survey Data Series 637, and data downloads are available at http://pubs.usgs.gov/ds/637/. Also, all Alaska Geochemical Database data have been incorporated into the interactive U.S. Geological Survey Mineral Resource Data web portal, available at http://mrdata.usgs.gov/.

  2. Environmental pollution by radioactive effluents: present situation facing the 21 Century. Part 1

    International Nuclear Information System (INIS)

    The awareness of the need to preserve the environment in the local, regional and international spheres has produced a large number of control and prevention rules that constitute the Environmental Law. The contamination of the sea has been the last field to be considered by the States. Since few years ago, marine pollution is appraised as an issue that affects all the States, taking account of its interdependency and the need to establish between governments a greater cooperation network. The radioactive contamination, i.e. the pollution produced by the discharge of radioactive wastes into the sea, is one of the types of contamination. Several discharge systems have been designed, so it is necessary to select in each case the most suitable one taking into account the type of wastes and other factors as the economy and the effectiveness of the method and the application of the radiation protection principles. International rules have evolved to solve different issues since the first United Nation Convention on the Law of the Sea in 1945 to the third Conference in 1982 that produced the United Nation Convention on the Law of the Sea and four Resolutions. The Convention and the Resolutions form an inseparable whole that show the evolution of the international cooperation in this field

This study contains an historical overview regarding human nutrition from the primitive forms until the paradoxes of contemporary alimentation. Nutritional education aims to inform and to train a person about food choices, dosage and cooking, how to identify authentic food and to understand the value of nutrition. Children need a balanced diet in order to grow and to become healthy adults. The importance of nutritional education in school is discussed taking into account the need of creating healthy eating habits which should be followed through the whole life, but also the lack of physical activity to children.

  9. Ministerial presentation: Republic of Korea [International ministerial conference on nuclear power for the 21st century

    International Nuclear Information System (INIS)

    His Excellency Myung Oh, Deputy Prime Minister and Minister of Science and Technology, Republic of Korea, noted that the peaceful use of nuclear energy has contributed greatly to a sustainable and stable supply of energy over the past 50 years. Over the last two decades energy and electricity consumption in the Republic of Korea (ROK) has increased more than fivefold and sevenfold, respectively, and the ROK is now one of the top ten energy consuming economies. Furthermore, it is expected that the consumption of energy and electricity will continue to rise by 50% and 70%, respectively, by 2020. Given the scarce indigenous energy resources available in the ROK, he stated his firm belief that the application of nuclear energy is inevitable for future economic development. The ROK has recently launched national research and development projects to develop the VHTR (very high temperature reactor), which can produce high temperatures for hydrogen production by nuclear power. He predicted another nuclear renaissance in the future. For this, the global community should assign a larger role to nuclear energy in, for example, space heating, hydrogen production, vehicle propulsion and seawater desalination, and expand the application of radioisotopes to various industries. He confirmed that peaceful uses of nuclear energy are inevitable and indispensable options for the reduction of greenhouse gas emissions and future welfare. He stated that the ROK appreciates the international nuclear society's efforts in strengthening the non-proliferation regime, and commented that in the ROK there have been various measures in this regard, including reinforcement of an export control regime and IAEA safeguard measures. He also indicated that recently the ROK has expanded nuclear research and development activities for the innovation of nuclear technologies and enhanced international cooperation by joining international nuclear cooperation projects, such as GIF (Generation IV International Forum) and the IAEA's International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO)

  10. Nuclear power in the 21st century

    International Nuclear Information System (INIS)

    Full text: All plausible long term energy scenarios project significant growth of global energy, especially if the Millennium Declaration on poverty eradication and the Plan of Implementation agreed at the World Summit on Sustainable Development (WSSD) are to be met. Projected growth is the fastest in developing countries. While growth for affordable energy services is not subject to debate really - the question is rather by how much - this is not the case for energy supply. 21st century energy supply systems face several challenges and uncertainties including energy resource availability, technology change, environmental compliance, reliability and security, political and social acceptance. One of the uncertainties concerns the role of nuclear power in 21st century energy supplies. Paradoxically, its near term role appears less certain that its longer term role. In the short-run, i.e., until 2020, most studies project either a slight increase, a slight decrease or no change at all. Though regional differences exist in terms of growth and decline, the effectively balance each other. Longer-term energy demand and supply studies, however, paint a different future. Analyses developed by international working groups generally project a potentially significant increase in the use of nuclear power. There are several reasons for this. Foremost, longer-term studies are not subjected to short-term policy constraints. Next, they do factor anticipated technology change and innovation into the analysis. Then resource depletion effects become more visible and environmental constraints become more stringent. The starting point of this paper is the Special Report on Emissions Scenarios (SRES) of the Intergovernmental Panel on Climate Change. Based on four of the SRES scenarios, one from each of the four SRES scenario families, this paper discusses the compatibility requirements of each for nuclear energy in terms of economics, environment, supply security, resources, waste

    Full Text Available The article presents historical analysis of formation of hygiene school of Dnipropetrovsk Medical Academy over the 100 year period - from formation of Katerinoslav province sanitary district council, as a unique self-government social organization in XIX century to the present. The basic stages of its development, including foundation of Hygiene Courses at High Mining School, their transformation into department of general hygiene, social hygiene and hygiene of labor in Katerinoslav Medical Academy in 1922, foundation of separate departments of hygiene in 1940-1948, their reorganization at the end of XX – beginning of XXI centuries are outlined. It is established, that Dnipropetrovsk hygiene school during its existence formed a great number of outstanding scientists, more than 100 dissertations in different directions devoted to hygienic diagnostics of technogenically changing environment, its impact on human health as well as hygienic control levers and health strengthening of population of industrial areas were defended. Scientific contribution of prominent scientists and teachers, their achievements and discoveries in the field of preventive medicine, role in the formation of preventive world outlook of students are estimated. At the XIV hygienic congress 30 hygienists were recognized as leading scientists of Ukraine over XX century, seven of them are from Dnipropetrovsk hygiene school; this indicates its importance in the noble cause of serving public health.

  3. Power generation alternatives for the XXI century

    International Nuclear Information System (INIS)

    Forecasts from different specialized sources indicate that the power consumption in the world will continue to increase. In Argentina it is expected that for the year 2020 the consumption will double the present values. In 2003, in our country, fossil fuels - carbon, oil, gas - contributed approximately 48% to the power generation, while hydroelectricity was 43% and nuclear power 9%. Fossil fuels have some advantages, main ones are present low cost and easy transport, but they have also many disadvantages in terms of contamination, environmental effects and non-renewable resources. The Carbon Dioxide (CO2), that is produced when burning fossil fuels, is considered as one of the major sources of global warming in earth (Greenhouse effect), with devastating climate consequences in certain regions as dry seasons, floods etc. In Argentina total CO2 emissions in year 1998 (last measured) were 114 million Tons. Although absolute emission values are not high, when compared with those of certain developed countries, some mitigation measures could be adopted. Emissions due to transport are diminishing thanks to a strong reconversion of public and private vehicles to run on natural gas instead of gasoline or diesel. But what are we going to do to optimize Power Generation lowering fossil fuels consumption? Some environmental NGO's insist that the only solution is to use the 'so called' renewable energies - Solar, Wind, Biomas, Geothermal - but these sources contribute only with less than 0,03% to Power Generation in our country. Figures provided by the World Energy Council shows that only 2% of Power used commercially all around the world comes from 'renewables'. Although this output could be increased in the future, WEC estimates very difficult to reach even 5% for year 2020 Solar energy is employed successfully in some countries to heat water for household purposes or to produce little amount of electricity for specific purposes. It is tempting to think that wind and sun

  5. Managing Reliability in the 21st Century

    Dellin, T.A.

    1998-11-23

    The rapid pace of change at Ike end of the 20th Century should continue unabated well into the 21st Century. The driver will be the marketplace imperative of "faster, better, cheaper." This imperative has already stimulated a revolution-in-engineering in design and manufacturing. In contrast, to date, reliability engineering has not undergone a similar level of change. It is critical that we implement a corresponding revolution-in-reliability-engineering as we enter the new millennium. If we are still using 20th Century reliability approaches in the 21st Century, then reliability issues will be the limiting factor in faster, better, and cheaper. At the heart of this reliability revolution will be a science-based approach to reliability engineering. Science-based reliability will enable building-in reliability, application-specific products, virtual qualification, and predictive maintenance. The purpose of this paper is to stimulate a dialogue on the future of reliability engineering. We will try to gaze into the crystal ball and predict some key issues that will drive reliability programs in the new millennium. In the 21st Century, we will demand more of our reliability programs. We will need the ability to make accurate reliability predictions that will enable optimizing cost, performance and time-to-market to meet the needs of every market segment. We will require that all of these new capabilities be in place prior to the stint of a product development cycle. The management of reliability programs will be driven by quantifiable metrics of value added to the organization business objectives.

  6. Making your presentation fun: creative presentation techniques

    KEENEN,MARTHA JANE

    2000-05-18

    What possesses someone to volunteer and go through hoops and red tape to make a presentation at a conference? For that matter, why does anyone ever present anything to anyone? Actually, presentations are a fact of life and there are many reasons for doing a presentation and doing it well. New and existing staff need training and orientation to the way things are done here. Handing all of them a manual and hoping they read it is pretty much a waste of paper. On the other hand, an effective, entertaining and upbeat presentation on the relevant topics is more likely to stick with those people. They will even have a name and face to remember and seek out when they have an issue on or with that topic. This can be a very effective beginning for networking with new peers. The presenter is seen as knowledgeable, as a source of information on company topics and possibly evaluated as a potential mentor or future manager. Project staff and/or peers benefit from clear, concise, presentations of topical knowledge. This is one way that a group working on various aspects of the same project or program can stay in touch and in step with each other. Most importantly, presentations may be the best or only door into the minds (and budgets) of management and customers. These presentations are a wonderful opportunity to address legal and compliance issues, budget, staffing, and services. Here is a chance, maybe the only one, to demonstrate and explain the wonderfulness of a program and the benefit they get by using the services offered most effectively. An interactive presentation on legal and compliance issues can be an effective tool in helping customers and/or management make good risk management decisions.

    The evolution of infrastructure networks such as roads and streets are of utmost importance to understand the evolution of urban systems. However, datasets describing these spatial objects are rare and sparse. The database presented here represents the road network at the french national level described in the historical map of Cassini in the $18^{th}$ century. The digitization of this historical map is based on a collaborative methodology that we describe in detail. This dataset can be used for a variety of interdisciplinary studies, covering multiple spatial resolutions and ranging from history, geography, urban economics to network science.

  9. Nuclear energy in this century - a bird in the hand

    International Nuclear Information System (INIS)

    This presentation reviews the past half-century of nuclear energy from one person's point of view, fully recognizing likely errors in fact and perception. It also takes a look at the coming 50 years of our enterprise. The future will demand a lot from nuclear technology, given the decline in the availability of cheap fossil fuels and the expected rising need for energy. We can supply safe and reliable energy for thousands of years, if such is necessary. Uncertainty remains in the short term regarding the support of the people and of the governments who serve them.

  16. Oblivion Deferred: Altichiero in the Fifteenth Century

    Directory of Open Access Journals (Sweden)

    2013-08-01

    Full Text Available Altichiero was the dominant north Italian painter of the later Trecento. In Padua, in the 1370s and early 1380s, he worked for patrons close to Petrarch and his circle and perhaps in direct contact with the poet himself. By the time of the second edition of Vasari's Vite (1568 the memory of Altichiero's work had suffered significant occlusion, and Vasari's account of him is little more than an appendix to his life of Carpaccio. Only since the later nineteenth century, and particularly in the last fifty or so years, has Altichiero's reputation been restored. It is the purpose of this paper to examine aspects of that reputation throughout the century or so after the painter's death (by April 1393.

    2000-01-01

    The past century of interstellar dust has brought us from first ignoring it to finding that it plays an important role in the evolution of galaxies. Current observational results in our galaxy provide a complex physical and chemical evolutionary picture of interstellar dust starting with the formation of small refractory particles in stellar atmospheres to their modification in diffuse and molecular clouds and ultimately to their contribution to star forming regions. Observations of the properties of dust in very young galaxies will be an important probe of the rates of star formation in terms of the production and destruction of dust grains. Future observations of dust at high spectral and spatial resolution will provide detailed information on processes in collapsing clouds up to star formation. Space missions to comets in the next century will first study them in situ but ultimately will bring back pristine nucleus material which will contain the end product of the collapsing protosolar molecular cloud at ...

  18. Snake oil for the 21st century.

    Science.gov (United States)

    Bigby, M

    1998-12-01

    Dermatology has been associated with quackery for at least a century. The dictionary defines a quack as "a pretender to medical knowledge or skill; ignorantly or falsely pretending to cure." The term quack is derived from quacksalver, or one who quacks like a duck in promoting his salves. Quacksalvers hacked many potions, including snake oil, with claims that it cured everything from dermatitis to rheumatism. With the current promulgation of skin "products" and their promotion and even sale by dermatologists, and the use of treatments of no proven efficacy, this association between dermatology and quackery is set to continue well into the 21st century. The list of offending treatments includes silicone gel sheets and onion extract cream (Mederma) for keloids, alpha-hydroxy acid creams and peels, topical ascorbic acid and phytonadione, "laser resurfacing," and cimetidine for warts, to name only a few.

    This paper explores the characteristics associated with marriages between Roman Catholics and members of other religious denominations ('mixed marriages') in 1911 Ireland. Using the recently-digitized returns of the 1911 census of population, we find that such marriages were relatively rare, varying from two to three percent of all mar- riages in Dublin to less than half a percent in Connacht. However, at the turn of the century in the Dublin area mixed marriages represented 12 per cent or mo...

    2013-12-01

    This is an encore presentation of what was presented at the 2012 AGU International Conference. It was entitled: 'The Importance of Water Conservation in the 21st Century.' The poster presentation, however, has been redesigned and reorganized with new, revised perspectives. The importance of water conservation principles has been emphasized. The population of United States has more than doubled over the past 50 years. The need for water however, has tripled. The EPA estimates that more than 36 states face water shortage during the forthcoming years. The EPA has prepared a plan for achieving environmental and energy performance. This will be coupled with leadership and accountability. Carbon neutrality is also of prime importance. The objective is to focus on six important, essential areas. 1. Efficient use of already available energy resources. 2. Intelligent water consumption and focusing on water conservation. 3. Expand the use of renewable energy resources. 4. Explore innovative transportation systems and methodologies. 5. Change building codes and promote high performance sustainable buildings. 6. Focus on developing creative environment management systems. Greenhouse gases such as carbon dioxide occur naturally in the atmosphere. Carbon dioxide is also emitted to the atmosphere through a variety of natural processes and also some human activities. However, fluorinated gases are emitted to the atmosphere solely through human activities, because they are created by humans. It is very important to observe that water conservation is probably the most cost-effective way to reduce our demand for water. Furthermore, it is certainly environmentally justifiable. The Environmental Protection Agency has a plan called E2PLAN. It is EPA's plan for achieving energy and environmental performance, leadership, accountability, and carbon neutrality. In June 2011, the EPA published a comprehensive, multi-year planning document called Strategic Sustainability Performance Plan. The

  17. The physiognomist's kidney in the fifteenth century.

    Science.gov (United States)

    Ziegler, Joseph

    2004-01-01

    Physiognomy, the art of deciphering a person's character and potential behavior by his or her external appearance, is an ancient body of knowledge which was gradually revived in the Latin West in the twelfth and particularly in the thirteenth century. This is a philological study of the scientific discourse about the physiognomy of the kidney in physiognomic sources from Pseudo-Aristotle's Physiognomonics (third century B.C.) through Pietro d'Abano's Liber compilationis phisonomie (ca 1295) to Rolandus Scriptoris's Reductorium phisonomie (ca 1430). Fifteenth-century learned physiognomists devoted specific chapters to the kidney. The physiognomists analyzed the fleshiness of the body-surface outside the kidneys (i.e. the loins and their vicinity). Firm loins denoted boldness, agility, and good fighting capacity and vice versa. The pre-modern kidney was of interest not only to physicians and surgeons wishing to treat kidney conditions and other pathologies arising from the urinary system. There were learned physicians who examined the body not to diagnose diseases, but to decipher their patient's personality. When engaged in this activity the kidneys, that is, the loins or the external area of the kidneys, were one of the body parts that could provide vital physiognomic information. PMID:15372426

  18. Ionizing radiation in 21st century

    International Nuclear Information System (INIS)

    The paper begins with the author's personal experience in Poland on the occasion of Chernobyl nuclear accident followed by main lessons that the author could deduce from the accident. After the discovery of ionizing radiation at the end of 19th century, social perception has altered between acceptance and rejection stemming from recognition of the basic aspects: usefulness for medical applications and for technical and scientific aims, beneficial effects of their low levels, and harmful effects of high levels. The author explains how linear no-threshold (LNT) assumption according to which even the lowest, near zero doses of radiation may cause cancer genetic harm has become established. Comparing the natural radioactivity of the earth's crust with the activity of much shorter-lived radioactive wastes from the nuclear power cycle, it is concluded that none of the man-made component of the radioactive wastes has higher-toxicity than the natural Th 232. The paper concludes by stating that one century has not been long enough to adapt mentally to ionizing radiation and radioactivity and perhaps 21st century will suffice for this adaptation. (S.

    2006-12-01

    Full Text Available Cracow, the old capital of Polish Kingdom, has always performed a particular role in the Polish history and culture. In the nineteenth century, particulary in the period of galician autonomy 1860-1914, Cracow became the spiritual capital of Poland for generations of Poles who lived in the partitioned country, which was ruled by the three foreign powers together. About this phenomenon decided not only the autonomy but also the old tradition and the symbolism of this town. In the 19 th century and before the First World War, Cracow was the most influential centre of the Polish national life. In this time Crakow’s citizens decided to continue the old tradition of the royal burial. Since there were no longer any Polish monarchs, they resolved that the remains of the greatest national heroes, of writers and artists be buried on the Wawel Cathedral in the cemetery Rakowice and later in the Church of Paulinites fathers “on the rock”. Famous funerals in 19 th century Cracow, of which the best known were those of prince Joseph Poniatowski in 1817, general Thaddeus Kosciusko in 1818, king Casmir the Great in 1869 and of poet Adam Mickiewicz in 1890 alluded to royal ceremonies from the time of Polish independence. These funerals have been one of the main elements in patriotic and religious ceremonies and important part of the nation’s patriotic educations.

  20. Worldwide surface temperature trends since the mid-19th century

    International Nuclear Information System (INIS)

    Sea surface temperatures (SSTs) for the period 1856 to the present have been corrected to compensate for the use of uninsulated buckets prior to the early 1940s. Trends in the corrected SST are consistent with trends in independently corrected nighttime marine air temperatures (NMAT).

The corrected SST anomalies are also compared with those of nearby coastal and island land air temperatures. Global-scale agreement is good except in the early 20th century when the land data were relatively warm by up to 0.2 C.

  1. Worldwide surface temperature trends since the mid-19th century

    International Nuclear Information System (INIS)

    Sea surface temperatures (SSTs) for the period 1856 to the present have been corrected to compensate for the use of uninsulated buckets prior to the early 1940s. Trends in the corrected SST are consistent with trends in independently corrected nighttime marine air temperatures (NMAT). Global-scale patterns of variation of annual anomalies of SST and NMAT, as revealed by the first three covariance eigenvectors, are also in close agreement. The corrected SST anomalies are also compared with those of nearby coastal and island land air temperatures. Global-scale agreement is good except in the early 20th century when the land data were relatively warm by up to 0.2 C. Proposed causes are the siting of thermometers in open-sided thatched sheds in tropical regions at that time, along with a marked tendency to warm westerly atmospheric circulation over Europe in winter.

    an ensemble of new artistic trends that appeared during the first half of the XIII century. Its spacious and monumental compositions present solutions that give the figures a quality of flexibility and breadth to their movements, while their faces resemble those of Antiquity. The space is indicated by architecture painted in an abbreviated manner, the iconostasis and icons are framed in an ornament of stucco bearing antique motifs, some scenes contain personifications, while the rich and harmonious colours and gold in the background emphasise the Hellenistic spirit. The frescoes in the Church of the Annunciation in the Gradac monastery, the endowment of Queen Jelena followed the trends in painting from Sopoćani. The figures in the narthex of the Church of St. George in Đurđevi Stupovi and in the parekklesion of the entrance tower, the endowment of King Dragutin, were painted in a rather similar fashion. The decoration of St. Ahilije in Arilje, the endowment of King Dragutin, consists of monumental figures of ancient beauty, richly painted architecture in the background, and greater depth painted in different forms of perspective and scenes containing details from everyday life. During the XIII century, the proportions of the compositions became larger, the number of participants in them increased, various episodes were added to the existing scenes, and the space was defined by a larger number of plans and buildings of ancient forms. At the same time, the painted architecture was presented in the perspective of different projections, deepening the space when necessary and highlighting the subject matter. The landscape is presented in the background, keeping to the rhythm of the scene or partitioning the episodes within the composition, while depicting vegetation and animals that resemble the mosaic flooring of ancient times. Special attention was paid to appearance and workmanship, to the modeling of the faces and human figures that acquired the proportions and

    According to studies by the Department of Energy, toward the latter part of this decade, we will have to add five or six baseload plants, and in the period from 2000 to 205, we are going to need some sixty additional baseload plants. So in the next fifteen years we will need some sixty-five or seventy baseload plants. One can argue over the accuracy of those numbers, but tens of new baseload plants are going to be needed, and that means we are going to have to start the design of these plants in the next few years to get them online by the end of the century. I think there is going to be a change in attitude towards new plants. My view is that when the American public is faced with the decision of what kind of new energy source they need versus 'do I let the lights dim?', that nuclear power will be one of their choices. We will see as a result the revival of nuclear power - the water reactors in the near term, and I will leave for later discussion the question of whether we will use breeders and gas-cooled reactors for the longer term

    Growing pressure on the world's water resources is having major impacts on our social and economic well-being. According to the United Nations, today, at least 1.1 billion people do not have access to clean drinking water. Pressures on water resources are likely to continue to worsen in response to decaying and crumbling infrastructure, continued population growth, climate change, degradation of water quality, and other challenges. If these challenges are not addressed, they pose future risks for many countries around the world, making it urgent that efforts are made to understand both the nature of the problems and the possible solutions that can effectively reduce the associated risks. There is growing understanding of the need to rethink governance to meet the 21st century water challenges. More and more water problems extend over traditional national boundaries and to the global community and the types and numbers of organizations addressing water issues are large and growing. Economic globalization and transnational organizations and activities point to the need for improving coordination and integration on addressing water issues, which are increasingly tied to food and energy security, trade, global climate change, and other international policies. We will present some of the key limitations of global water governance institutions and provide recommendations for improving these institutions to address 21st century global water challenges more effectively.

    Full Text Available The paper reviewed the emerging roles of the 21st century librarians, charged with the responsibility to manage repository services across libraries in present-day information technology environment. Librarians need to be trained and empowered with requisite skills and knowledge needed for successful management of the ICT driven repository initiatives that the 21st century demands. Literature was reviewed on the roles and responsibilities of librarians, training needs and opportunities, career path and recruitment of librarians, and community support necessary for effective and efficient implementation and management of repository initiatives. This entails the ability to comprehend trends and change patterns which are essential for providing research focused and user-friendly models in open repository services that are based on thorough analytical understanding of the challenges of emerging trends. To achieve this requires the training and retraining of librarians to reposition them as information specialists in their career path. The role of the library as an integral part of its social environment is to educate the community about the existence of an open repository by building partnership with community-oriented research centres through seminars, workshops, symposium, training, and awareness programmes. The study recommends that librarians should strategize and collaborate with researchers to make open repository an essential research tool.

  10. Memoirs a twentieth-century journey in science and politics

    Teller, Edward

    2001-01-01

    The story of Edward Teller is the story of the twentieth century. Born in Hungary in 1908, Teller witnessed the rise of Nazism and anti-Semitism, two world wars, the McCarthy era, and the changing face of big science. A brilliant and controversial figure whose work on nuclear weapons was key to the American war effort, Teller has long believed in freedom through strong defense, a philosophy reflected in his stance on arms control and nuclear policy. These extraordinary recollections at last reveal the man behind the headlines-passionate and humorous, devoted and loyal. In clear and compelling prose, Teller tells of the people, events, and ideas that shaped him as a scientist, beginning with his early love of music and math, and continuing with his study of quantum physics with Werner Heisenberg. Present at many of the pivotal moments in modern science, Teller also describes his friendships with some of the century's greatest minds-Einstein, Bohr, Fermi, Szilard, von Neumann, Oppenheimer-and offers an honest a...

  11. Atomism, Lynceus, and the fate of seventeenth-century microscopy.

    Science.gov (United States)

    Lüthy, C H

    1996-01-01

    Recent scholarship, focusing on the rapid decline of microscopy after the late 1680's, has shown that the limitations of microscopy and the ambivalent meaning of its findings led to a wide-spread sense of frustration with the new instrument. The present article tries to connect this fall from favor with the microscope's equally surprising but hitherto little noticed late rise to prominence. The crucial point is that when the microscope, more than a decade after the telescope, finally managed to arouse the interest of natural philosophers, it did so as a corpuscularian tool, and as such it came to share the difficult fate of seventeenth-century corpuscularianism. The essay ends with the claim that the fall of microscopy was not only due to the failure of microscopy to corroborate corpuscularianism, but also to the changing definition of natural philosophy in the late seventeenth and early eighteenth centuries and to the separation of the domains of living matter (to which the microscope found itself confined) from a physica whose recent mathematical framework excluded the organic world.

    Guzman, Miguel; Judkins, Alexander R

    2009-04-01

    Digital pathology represents an electronic environment for performing pathologic analysis and managing the information associated with this activity. The technology to create and support digital pathology has largely developed over the last decade. The use of digital pathology tools is essential to adapt and lead in the rapidly changing environment of 21st century neuropathology. The utility of digital pathology has already been demonstrated by pathologists in several areas including consensus reviews, quality assurance (Q/A), tissue microarrays (TMAs), education and proficiency testing. These utilities notwithstanding, interface issues, storage and image formatting all present challenges to the integration of digital pathology into the neuropathology work environment. With continued technologic improvements, as well as the introduction of fluorescent side scanning and multispectral detection, future developments in digital pathology offer the promise of adding powerful analytic tools to the pathology work environment. The integration of digital pathology with biorepositories offers particular promise for neuropathologists engaged in tissue banking. The utilization of these tools will be essential for neuropathologists to continue as leaders in diagnostics, translational research and basic science in the 21st century. PMID:19290997

    We present revised probability density functions for climate model parameters (effective climate sensitivity, the rate of deep-ocean heat uptake, and the strength of the net aerosol forcing) that are based on climate change observations from the 20th century. First, we compare observed changes in surface, upper-air, and deep-ocean temperature changes against simulations of 20th century climate in which the climate model parameters were systematically varied. The estimated 90% range of effective climate sensitivity is 2-5 K but no corresponding upper bound can be placed on the equilibrium climate sensitivity. The net aerosol forcing strength for the 1980s has 90% bounds of -0.70 to -0.27 Wm-2. The rate of deep-ocean heat uptake corresponds to an effective diffusivity, Kv, with a 90% range of 0.04-4.1 cm2s-1. Second, we estimate the effective climate sensitivity and rate of deep-ocean heat uptake for 11 of the IPCC AR4 AOGCMs. By comparing against the acceptable combinations inferred from the observations, we conclude that the rates of deep-ocean heat uptake for the majority of AOGCMs lie above the observationally based median value. This implies a bias in the predictions inferred from the IPCC models alone.

    In the present stage of accelerated development of science and technology at the turn of the century it may be deemed that the geological science in China is destined to prosper, as viewed from the increasing society needs, the scientific problems and the basic technological background provided by the society, the three basic elements for the development of science. Owing to the sagacity and foresight of the founders of geology in China, Chinese geological research had already won a world fame in 1920s to 1930s. From the 1950s to 1970s the geological science in China had undergone a rapid development. From the end of 1970s onwards the geological science in China had undergone an overall development. With the acceptance of the new concept of Earth System Science by the majority of geologists, all branches of geological studies will merge into a comprehensive and coordinate research and the geological science in China will be facing an entirely new stage of development in the 21st century.

    The authors propose a manual measurement method for wear in total hip arthroplasty (PowerPoint method) based on the well-known Microsoft PowerPoint software (Microsoft Corporation, Redmond, Wash). In addition, the accuracy and reproducibility of the devised method were quantified and compared with two methods previously described by Livermore and Dorr, and accuracies were determined at different degrees of wear. The 57 hips recruited were allocated to: class 1 (retrieval series), class 2 (clinical series), and class 3 (a repeat film analysis series). The PowerPoint method was found to have good reproducibility and to better detect wear differences between classes. The devised method can be easily used for recording wear at follow-up visits and could be used as a supplementary method when computerized methods cannot be employed. PMID:19896061

    Full Text Available The ozone chemistry over three centuries has been simulated based on climate prediction from a global climate model and constant anthropogenic emissions in order to separate out the effects on air pollution from climate change. Four decades in different centuries has been simulated using the chemistry version of the atmospheric long-range transport model; the Danish Eulerian Hemispheric Model (DEHM forced with meteorology predicted by the ECHAM5/MPI-OM coupled Atmosphere-Ocean General Circulation Model. The largest changes in both meteorology, ozone and its precursors is found in the 21st century, however, also significant changes are found in the 22nd century. At surface level the ozone concentration is predicted to increase due to climate change in the areas where substantial amounts of ozone precursors are emitted. Elsewhere a significant decrease is predicted at the surface. In the free troposphere a general increase is found in the entire Northern Hemisphere except in the tropics, where the ozone concentration is decreasing. In the Arctic the ozone concentration will increase in the entire air column, which most likely is due to changes in transport. The change in temperature, humidity and the naturally emitted Volatile Organic Compounds (VOCs are governing with respect to changes in ozone both in the past, present and future century.

    Federal laboratories have successfully filled many roles for the public; however, as the 21st Century nears it is time to rethink and reevaluate how Federal laboratories can better support the public and identify new roles for this class of publicly-owned institutions. The productivity of the Federal laboratory system can be increased by making use of public outcome metrics, by benchmarking laboratories, by deploying innovative new governance models, by partnerships of Federal laboratories with universities and companies, and by accelerating the transition of federal laboratories and the agencies that own them into learning organizations. The authors must learn how government-owned laboratories in other countries serve their public. Taiwan`s government laboratory, Industrial Technology Research Institute, has been particularly successful in promoting economic growth. It is time to stop operating Federal laboratories as monopoly institutions; therefore, competition between Federal laboratories must be promoted. Additionally, Federal laboratories capable of addressing emerging 21st century public problems must be identified and given the challenge of serving the public in innovative new ways. Increased investment in case studies of particular programs at Federal laboratories and research on the public utility of a system of Federal laboratories could lead to increased productivity of laboratories. Elimination of risk-averse Federal laboratory and agency bureaucracies would also have dramatic impact on the productivity of the Federal laboratory system. Appropriately used, the US Federal laboratory system offers the US an innovative advantage over other nations.

    2015-01-01

    This final entry in the History of Human Space Exploration mini-series by Ben Evans continues with an in-depth look at the latter part of the 20th century and the start of the new millennium. Picking up where Partnership in Space left off, the story commemorating the evolution of manned space exploration unfolds in further detail. More than fifty years after Yuri Gagarin’s pioneering journey into space, Evans extends his overview of how that momentous voyage continued through the decades which followed. The Twenty-first Century in Space, the sixth book in the series, explores how the fledgling partnership between the United States and Russia in the 1990s gradually bore fruit and laid the groundwork for today’s International Space Station. The narrative follows the convergence of the Shuttle and Mir programs, together with standalone missions, including servicing the Hubble Space Telescope, many of whose technical and human lessons enabled the first efforts to build the ISS in orbit. The book also looks to...

  11. Astrology in seventeenth-century Peru.

    Science.gov (United States)

    Brosseder, Claudia

    2010-06-01

    This article discusses three aspects of the history of astrology in seventeenth-century Peru that are of larger interest for the history of science in Latin America: Creole concerns about indigenous idolatry, the impact of the Inquisition on natural philosophy, and communication between scholars within the Spanish colonies and the transatlantic world. Drawing mainly on the scholars Antonio de la Calancha, Juan de Figueroa, and Ruiz de Lozano, along with several Jesuits, the article analyzes how natural and medical astrology took shape in Peru and how they fostered astronomical investigations of the southern skies. While natural and medical astrology, showing New and Old World influences, oscillated between orthodoxy and heterodoxy, and between scholasticism and new science, judicial astrology remained undeveloped. Toward the end of the seventeenth century the discourse about astrology took an unexpected turn, reflecting a newly invigorated moral and Christian reading of the heavens that was in part a response to a deep-rooted dissatisfaction with the failure of the extirpation of idolatry campaigns. Inscribing divine and cardinal virtues, the Virgin Mary, Christian saints, and Greco-Roman allegories into the heavens was considered a way to finally solve the problem of idolatry and to convey Creole greatness.

    2007-01-01

    We are truly fortunate to live in one of the great epochs of human discovery, a time when science is providing new visions and understanding about ourselves and the world in which we live. At last, we are beginning to explore the Universe itself. One particularly exciting area of advancement is high-energy physics where several existing concepts will be put to the test. A brief survey will be given of accomplishments in 20th Century physics. These include relativity and quantum physics which have produced breakthroughs in cosmology, astrophysics, and high-energy particle physics. The current situation is then assessed, combining the last 100 years of progress with new 21st Century challenges about unification and where to go next. Finally, the future is upon us. The next frontier in experimental high-energy physics, the Large Hadron Collider (LHC) at CERN in Geneva, is scheduled to begin coming online this year (2007). The potential for the LHC to address several of the significant problems in physics today will be discussed, as this great accelerator examines the predictions of the Standard Model of particle physics and even cosmology. New physics and new science will surely emerge and a better vision of the world will unfold.

  13. A century of induced earthquakes in Oklahoma?

    Science.gov (United States)

    Hough, Susan E.; Page, Morgan T.

    2015-01-01

    Seismicity rates have increased sharply since 2009 in the central and eastern United States, with especially high rates of activity in the state of Oklahoma. Growing evidence indicates that many of these events are induced, primarily by injection of wastewater in deep disposal wells. The upsurge in activity has raised two questions: What is the background rate of tectonic earthquakes in Oklahoma? How much has the rate varied throughout historical and early instrumental times? In this article, we show that (1) seismicity rates since 2009 surpass previously observed rates throughout the twentieth century; (2) several lines of evidence suggest that most of the significant earthquakes in Oklahoma during the twentieth century were likely induced by oil production activities, as they exhibit statistically significant temporal and spatial correspondence with disposal wells, and intensity measurements for the 1952 El Reno earthquake and possibly the 1956 Tulsa County earthquake follow the pattern observed in other induced earthquakes; and (3) there is evidence for a low level of tectonic seismicity in southeastern Oklahoma associated with the Ouachita structural belt. The 22 October 1882 Choctaw Nation earthquake, for which we estimate Mw 4.8, occurred in this zone.

  14. Bilingualism and memory: early 19th century ideas about the significance of polyglot aphasia.

    Science.gov (United States)

    Lorch, Marjorie

    2007-07-01

    In the second half of the 19th century, there was very little attention given to bilingual speakers within the growing clinical literature on aphasia. The first major publication on this topic (Pitres, 1895), appeared three decades after Broca's seminal work. Previously, Ribot (1881) had discussed the phenomenon of bilingual aphasia in the context of diseases of memory. Although interest in the neurological basis of the language faculty was in fact present throughout the century, the theoretical implications of the knowledge of more than one language did not appear to be linked to this issue. A number of British authors writing in the first half of the 19th century have been identified who did consider the significance of these cases. Importantly, these writers speculated on the implication of bilingual aphasia specifically with regard to ideas about memory rather than language. Consideration of these writings helps to illuminate the history of ideas about the organization of language in the brain. PMID:17715800

    2011-09-01

    This work presents a statistical study of vibrato parameters in soprano voices. More than one hundred recordings of the same tone sung by 75 artists have been analyzed. Vibrato rate and extent, tone length and intonation, together with their correlations are the main parameters under examination. The study shows a clear decrease of the mean vibrato rate during the last century (-1.8±0.3 Hz/century), together with an increase of vibrato extent (56.4±0.3cent/century). Vibrato rate and extent show a statistically significant negative correlation (r=-0.62). Vibrato rate increase near the end of the tone has been observed too, in agreement with previous measurements, together with a mean increase of the pitch of the tone. A small positive correlation has been also found among note duration and vibrato extent. PMID:21895105

This century is the century of extremes -- political, economic, social, and global black-swan events happening with increasing frequency and severity. Book of Extremes is a tour of the current reality as seen through the lens of complexity theory – the only theory capable of explaining why the Arab Spring happened and why it will happen again; why social networks in the virtual world behave like flashmobs in the physical world; why financial bubbles blow up in our faces and will grow and burst again; why the rich get richer and will continue to get richer regardless of governmental policies; why the future of economic wealth and national power lies in comparative advantage and global trade; why natural disasters will continue to get bigger and happen more frequently; and why the Internet – invented by the US -- is headed for a global monopoly controlled by a non-US corporation. It is also about the extreme innovations and heroic innovators yet t...

  19. Alarm filtering and presentation

    International Nuclear Information System (INIS)

    This paper discusses alarm filtering and presentation in the control room of nuclear and other process control plants. Alarm generation and presentation is widely recognized as a general process control problem. Alarm systems often fail to provide meaningful alarms to operators. Alarm generation and presentation is an area in which computer aiding is feasible and provides clear benefits. Therefore, researchers have developed several computerized alarm filtering and presentation approaches. This paper discusses problems associated with alarm generation and presentation. Approaches to improving the alarm situation and installation issues of alarm system improvements are discussed. The impact of artificial intelligence (AI) technology on alarm system improvements is assessed. (orig.)

    International Nuclear Information System (INIS)

    The Department of Energy is supporting a number of programs directed at improving nuclear power's ability to compete by the mid 1990s in providing some of what will be urgently needed new baseload capacity, and at meeting both utility requirements and public goals. More specifically, we are co-funding demonstration by 1993 of the process for life extension of current nuclear plants. We are supporting the development of new ALWR designs which rely more on methods such as natural circulation, gravity, reduced power density, or the characteristics of materials, rather than engineered systems to provide safety. These designs will meet the criteria set forth in EPRI's Utility Requirements Documents. We have established a cost-sharing program to demonstrate the success of the nuclear plant standardization and licensing process by obtaining NRC certification by 1992 or 1993 of two evolutionary 1300MWe ALWR designs. We are also cost-sharing a program to certify by 1995 passively safe 600MWe ALWRs employing more natural safety features and modular construction. These programs will involve a rule-making hearing process. We are supporting the development and possible certification early in the next century of modular high temperature gas reactor and advanced liquid metal reactor plant designs. We are planning to demonstrate the early site approval licensing process through a cost-sharing arrangement with the private sector by 1995. In developing the National Energy Strategy, we are examining the issue of a fully satisfactory regulatory process, including the possibility of legislation codifying 10 CFR Part 52, limiting the possible delays associated with a potential second hearing and dealing with emergency planning issues before start of construction. We recently announced a restructured plan to develop a permanent waste repository by 2010. By 1995 we expect to have made significant progress in evaluating the suitability of Yucca Mountain. We expect to have selected a

    Science.gov (United States)

    Nascimento, Osvaldo J M

    2013-09-01

    Leprosy is a chronic infectious peripheral neuropathy caused by Mycobacterium leprae. The different clinical presentations of the disease are determined by the quality of the host immune response. Early detection of leprosy and treatment by multidrug therapy are the most important steps in preventing deformity and disability. Thus the early recognition of the clinical leprosy presentation is essential. Mononeuritis, mononeuritis multiplex (MM), polyneuritis (MM summation) are the most frequent. The frequent anesthetic skin lesions are absent in the pure neuritic leprosy presentation form. Isolated peripheral nerve involvement is common, including the cranial ones. Arthritic presentation is occasionally seen, usually misdiagnosed as rheumatoid arthritis. Attention should be given to autonomic dysfunctions in leprosy. There are clinical presentations with severe neuropathic pain - painful small-fiber neuropathy. Leprous late-onset neuropathy (LLON) clinical presentation should be considered facing a patient who develop an inflammatory neuropathy many years after a previous skin leprosy treatment.

  9. Imagining the Twentieth Century: Retrospective, Myth, and the Colonial Question

    Directory of Open Access Journals (Sweden)

    David B MacDonald

    2007-01-01

    Full Text Available Retrospectives on the twentieth century often portray it as the most atrocious century in human history, in terms of totalising ideologies, moral abandonment, technological horror, and mass death. The nineteenth and earlier centuries, by contrast, emerge as progressive and enlightened eras, characterised by morality, rationalism, and the absence of war. Creating a dramatic contrast between old and new centuries ignores the historical reality of colonialism and violence outside Europe’s borders. This article problematises twentieth century retrospectives and their nostalgia for the past, comparing these with recent histories of colonialism and genocide. Rather than see the twentieth century as a decisive break from the past, there are important elements of continuity and evolution which should not be ignored.

    Full Text Available In western Cornwall production of pottery in the local gabbroic fabric seems to have continued throughout the 5th century. Very small quantities reached sites in north-east Cornwall and south Devon. The date at which pottery use ended in the remainder of Devon cannot be established at present. In the final phase the pottery in use consisted almost entirely of South Devon ware and BB1 from south-east Dorset; at Exeter importation of both wares ceased at about the same time. Changes in the latest coarse ware forms are discussed, and the importance of post-Roman Mediterranean imports in dating the end of the Romano-British industries is highlighted.

As part of the American Journal of Orthodontics and Dentofacial Orthopedics' Centennial celebration, we present 100 people who most influenced the specialty during the last 100 years. Part 2 picks up with "the greatest generation" and describes those born in the first 2 decades of the 20th century. Whether born in Europe or the United States, their lives and educations were disrupted by world war. Many served during the years of conflict, and a few paid an even heavier price. After World War II, they returned home or immigrated to the United States and resumed their life's work in orthodontics. PMID:26232830

    2014-12-01

    Full Text Available This paper presents and analyzes the criticisms made by intellectuals of the nineteenth century towards sports. From different fields of knowledge (evolutionary philosophy, anthropology and economics Herbert Spencer (1860/1904, Edward Tylor (1881/1973 and Thorstein Veblen (1899/2005 agreed to question the primacy of sports over traditional practices, rituals and folk. These authors, without reaching the ends of the luddites respect of industrial machines, extolled the unfavorable aspects of physical exercises, planting a seed of doubt that continues to this day. The importance of knowing these arguments lies in the way they faced the sporting phenomenon when it began to be institutionalized in a new set of corporal, transformative exercises and apparently a generator of fitness and health

  13. The Stability of F-star Brightness on Century Timescales

    CERN Document Server

    Lund, Michael B; Stassun, Keivan G; Hippke, Michael; Angerhausen, Daniel

    2016-01-01

    The century-long photometric record of the DASCH project provides a unique window into the variability of stars normally considered to be photometrically inactive. In this paper, we look for long-term trends in the brightness of F stars, with particular attention to KIC 8462852,an F3 main sequence star that has been identified as significant short-term variability according to Kepler observations. Although a simple search for variability suggests long-term dimming of a number of F stars, we find that such trends are artifacts of the 'Menzel Gap' in the DASCH data. That includes the behavior of KIC 8462852, which we believe is consistent with constant flux over the full duration of observations. We do, however, present a selection of F stars thatdo have significant photometric trends, even after systematics are taken into account.

    Science.gov (United States)

    Dürrigl, M A; Fatović-Ferencić, S

    2001-12-01

    We explored the notions of life and death as perceived and presented in a 15th century Croatian literary text, Slovo Mestra Polikarpa, in which master Polikarp, a well-learned man of medieval times, engages in a lengthy dialogue with Death itself. This contrast/debate is a rare piece of medieval literature, not only by its Old Croatian language, but also by the angular Glagolitic script in which it was written. As a part of Croatian cultural heritage, it is deeply rooted in and clearly belongs to the common context of Western European medieval views on life, health, ailing, and death. A medieval perspective on such issues might be interesting to broad readership and, in many aspects, to medical professionals, whose everyday practice necessarily involves not only practical and scientific, but also moral, philosophical, and religious deliberations about life and death.

This period has been selected for on the one hand it covers the final years of the Polynesian culture before it was deeply influenced by good intended efforts of missionaries and administrators who tried to erase heathen customs and introduce dresses, and introducing reading and writing and the negative forces of traders, whalers and colonizers, who came to the islands to relax after arduous travels, and to buy cheap goods and food. On the other hand many voyagers, missionaries, administrators and traders left us in their logs and journals detailed descriptions of the islanders and their cultures as they had seen them and tried to understand them. These publications will be considered here as ‘sources’.

    2015-02-20

    This article emphasises the importance of effective presentation skills. Such skills allow nurses to share knowledge and expertise and to communicate clearly in a range of workplace scenarios. Nurses are increasingly being asked to present in formal and informal situations, such as conferences, poster presentations, job interviews, case reports and ward-based teaching. This article explores the principles underpinning the development of these skills, discusses the situations in which they could be applied and demonstrates how nurses might improve and develop as presenters.

    To more fully understand nineteenth-century literary production, literary scholars must consider periodical editing as more than biographical footnotes to the lives of famous Victorian authors or secondary details in a text’s publishing history. In The Editor as Producer: Nineteenth-Century British Literary Editors, I seek to render more visible the work of the periodical editor, positing this figure as pivotal to the nineteenth-century literary scene.

  19. Changes in frost days in simulations of twentyfirst century climate

    Global coupled climate model simulations of twentieth and twentyfirst century climate are analyzed for changes in frost days (defined as nighttime minima less than freezing). The model simulations agree with the observed pattern for late twentieth century of a greater decrease of frost days in the west and southwest USA compared to the rest of the country, and almost no change in frost days in fall compared to relatively larger decreases in spring. Associated with general increases of nighttime minimum temperatures, in the future climate with increased greenhouse gases (GHGs) the number of frost days is fewer almost everywhere, but there are greatest decreases over the western parts of the continents. The numbers of frost days are most consistently related to sea level pressure, with more frost days occurring when high pressure dominates on the monthly time scale in association with clearer skies and lower nighttime minimum temperatures. Spatial patterns of relative changes of frost days are indicative of regional scale atmospheric circulation changes that affect nighttime minimum temperatures. Increases of soil moisture and clouds also contribute, but play secondary roles. The linkages among soil moisture, clouds, sea level pressure, and diurnal temperature range are quantified by a statistical multiple regression model. Coefficients for present and future climate are similar among the predictors, indicating physical processes that affect frost days in present and future climates do not appreciably change. Only the intercept changes in association with the significant warming of the mean climate state. This study highlights the fact that, though there is a general decrease in the number of frost days with global warming, the processes that affect the pattern of those changes, and thus the regional changes of frost days, are influenced by several interrelated physical processes, with changes in regional atmospheric circulation generally being most important.

    Full Text Available The article systematically examines the course of major financial crises of the late nineteenth century (the crises of 1848, 1857, 1873 in the financial centers of Ukraine at that time, namely Kуiv, Lviv, Odessa. The paper shows the specifics of these financial centers connected with the investments in profitable sugar industry of Kyiv; with the international trade and massive exports of grain in Odessa; with the beginning of Galician oil extraction and the creation of numerous oil companies in Lviv. After brief description of these crises in the world the author provides the numerous examples for each of the financial centers revealing their specificity inUkraine. The main emphasis is given on the impact of the crises on securities markets, particularly on the dynamics of stock prices.

  3. Towards a nuclear-weapon-free century

    International Nuclear Information System (INIS)

    In the last century, the rapid progress in science and technology enabled richer and more comfortable lives, but the other side of this double-edged sword is that science and technology have also been used to develop and improve high-tech weaponry. Due to this fact, deployed around the world are tens of thousands of nuclear weapons, and detonation of only a few of them would kill some hundreds of million of people and destroy out civilization. The human race stands at a crossroad. What should be done? It is a crucially important responsibility for the Japanese government to work for peace in which there will be no fear or threat of nuclear weapons

  4. Radiology in the 21st century

    International Nuclear Information System (INIS)

    On the leading edge in ''high-tech'' medicine, radiology is experiencing several revolutions simultaneously that promise an exciting future. New imaging methods and digital technologies not only offer novel ways to view tissues but also provide opportunities for quantitative evaluation of function and even permit determination of metabolic status. New approaches to technology assessment are being explored that alter the ways in which equipment and procedures are introduced into clinical medicine. With the plethora of radiology services available, the radiologist must serve as a consultant in the triage of patients in radiology and the dissemination of information from radiology. For similar reasons, training in diagnostic radiology may eventually accommodate to the concept of specialization along organ-system lines. Without question, radiology is destined for an exciting period as it moves into the 21st century

    1978-01-01

    Reasonable evolutionary trends in federal outlays for aerospace research and development predict a continuing decline in real resources (1970 dollars) until the mid eighties, and a growth thereafter to the 1970 level by 2000, still well below the 1966 peak. Employment levels will parallel this trend with no shortage of available personnel foreseen. These trends characterize a maturing industry. Shifts in outlook toward the economic use of resources, rather than minimum risk at any cost, and toward missions aligned with societal needs and broad national goals will accompany these trends. These shifts in outlook will arise in part in academia, and will, in turn, influence engineering education. By 2000, space technology will have achieved major advances in the management of information, in space transportation, in space structures, and in energy. The economics of space systems must be the primary consideration if the space program foreseen for the 21st century is to become an actuality.

    Leaders know how to achieve goals and inspire people along the way. While the terms and definitions may change with the times, it is important to understand the skills and abilities needed to lead in the 21st century. Most effective leaders have one element in common, and that is they are able to keep their teams engaged. If team members are not engaged, they may very well leave the organization. With four generations in the workplace, leaders must adapt and modify their leadership style in order to maintain employee engagement. The ability to lead effectively is based on a number of skills, including communication, motivation, vision, modeling, demonstrating empathy, confidence, persistence, and integrity. PMID:26710571

    Wedrychowicz, Halina

    2015-06-01

    Demands for effective vaccines to control parasitic diseases of humans and livestock have been recently exacerbated by the development of resistance of most pathogenic parasites to anti-parasitic drugs. Novel genomic and proteomic technologies have provided opportunities for the discovery and improvement of DNA vaccines which are relatively easy as well as cheap to fabricate and stable at room temperatures. However, their main limitation is rather poor immunogenicity, which makes it necessary to couple the antigens with adjuvant molecules. This paper review recent advances in the development of DNA vaccines to some pathogenic protozoa and helminths. Numerous studies were conducted over the past 14 years of 21st century, employing various administration techniques, adjuvants and new immunogenic antigens to increase efficacy of DNA vaccines. Unfortunately, the results have not been rewarding. Further research is necessary using more extensive combinations of antigens; alternate delivery systems and more efficient adjuvants based on knowledge of the immunomodulatory capacities of parasitic protozoa and helminths.

    Environmental changes strongly impact the distribution of species and subsequently the composition of species assemblages. Although most community ecology studies represent temporal snap shots, long-term observations are rather rare. However, only such time series allow the identification of species composition shifts over several decades or even centuries. We analyzed changes in the species composition of a southeastern German butterfly and burnet moth community over nearly 2 centuries (1840-2013). We classified all species observed over this period according to their ecological tolerance, thereby assessing their degree of habitat specialisation. This classification was based on traits of the butterfly and burnet moth species and on their larval host plants. We collected data on temperature and precipitation for our study area over the same period. The number of species declined substantially from 1840 (117 species) to 2013 (71 species). The proportion of habitat specialists decreased, and most of these are currently endangered. In contrast, the proportion of habitat generalists increased. Species with restricted dispersal behavior and species in need of areas poor in soil nutrients had severe losses. Furthermore, our data indicated a decrease in species composition similarity between different decades over time. These data on species composition changes and the general trends of modifications may reflect effects from climate change and atmospheric nitrogen loads, as indicated by the ecological characteristics of host plant species and local changes in habitat configuration with increasing fragmentation. Our observation of major declines over time of currently threatened and protected species shows the importance of efficient conservation strategies. PMID:26743786

  11. Revolutions in twentieth-century physics

    International Nuclear Information System (INIS)

    Relativity theory, quantum mechanics, elementary-particle physics, and cosmology are the four pillars of modern physics. The life in the 21th century is without them no more conceivable: The special relativity theory renewed our understanding of space and time, on the laws of quantum mechanics are based countless everyday objects like transistors, computer chips, and mobile telephones; in particle accelerators we study the components oof matter, and with telescopes we take an ever deeper look in the past of the universe. Taking reference books to these themes at hand, one is overwhelmed by the plethora and complexity of the mathematical formulas. This book of the renowned professor of physics David J. Griffiths id refreshingly different. By means of many illustrative examples and entertaining stories it introducts to the themes and helps the reader also without a large mathematical apparatus to a fundamental understanding of that, about which Einstein, Schroedinger, Heisenberg, and Hubble actually thought and spoke. In each chapter numerous, pedagogically selected examples are completely worked out, in order to fill the matter with life. Moreover the text contains a manifold of problems, which allow the reader to deepen his knowledge and apply immediately. Griffith's ''Revolution in Twentieth Century Physics'' appeals not only to pupils and future studyings of natural sciences, who want to get an appetite for what lies ahead, but also to interested readers, which have already heared in the media from quarks and quanta, the curved space-time, Albert Einstein, and the big bang and now want to understandably know what is at stake in all the excitement.

  12. Acoustic emission: The first half century

    1994-08-01

    The technology of acoustic emission (AE) is approaching the half century mark, having had its beginning in 1950 with the work of Joseph Kaiser. During the 1950s and 1960s researchers delved into the fundamentals of acoustic emission, developed instrumentation specifically for AE, and characterized the AE behavior of many materials. AE was starting to be recognized for its unique capabilities as an NDT method for monitoring dynamic processes. In the decade of the 1970s research activities became more coordinated and directed with the formation of the working groups, and its use as an NDT method continued to increase for industrial applications. In the 1980s the computer became a basic component for both instrumentation and data analysis, and today it has sparked a resurgence of opportunities for research and development. Today we are seeing a transition to waveform-based AE analysis and a shift in AE activities with more emphasis on applications than on research. From the beginning, we have been fortunate to have had so many dedicated savants with different fields of expertise contribute in a collective way to bring AE to a mature, fully developed technology and leave a legacy of knowledge recorded in its literature. AE literature has been a key indicator of the amount of activity, the proportion of research to application, the emphasis on what was of current interest, and the direction AE has taken. The following is a brief survey of the history of acoustic emission with emphasis on development of the infrastructure over the past half century.

Dimitrie Onciul 23e25, Sector 2, 024053 Bucharest, Romania Razelm-Sinoe Lagoon System, situated in the NW part of the Black Sea, in tight connection with the Danube Delta, has been subject to major changes due to human interventions in the past century. These changes have resulted into a complete change of the Lagoon specific ecosystems compared to its pristine state. In its natural state, as brackish - transitional environment, Antipa (1894) mentions Razelm Lagoon as one of the places with the greatest fisheries around the Black Sea coast (about 1879 - 1884, there were approximately 10,000 fishermen, all working on the Razelm Sinoe Lagoon System). Starting with the end of the XIXth Century, new canals were dug and existing channels were dredged in order to develop tighter connections with the Danube River. The natural inlet of Portita was blocked four decades ago and connections between the various parts of the lagoon system were controlled by the building of locks and sluices. The 2 inlets of Sinoe Lagoon were also controlled during early 1980s. Under these conditions, the lagoon ecosystem changed from brackish towards freshwater, with major effects on the existing flora and fauna. The period of brutal interventions ended in 1989 and the Razelm-Sinoe Lagoon System became part of the Danube Delta Biosphere Reserve in 1991, with a strict policy of nature protection and restoration. Spatial planning has been the major management option for the entire reserve, lagoon system included. Plans for sustainable development of the Razelm-Sinoe Lagoon System have been built in a participative manner, involving the local stakeholders, as part of FP7 ARCH project. Special attention has been given to impacts of climate change. The study presents the vision for the development Razelm-Sinoe Lagoon System over

    2014-02-01

    A review of half a century of cosmology is presented for an intended audience of elementary particle physicists. The review is based on a half-hour seminar talk (at the Institute of Theoretical and Experimental Physics, ITEP) and is therefore brief and superficial. The introductory historical section is mostly devoted to the fundamental work done in, but not always known outside, Russia (USSR). Foundational works and astronomical observations instrumental in shaping the field are discussed, as are inflation, baryosynthesis, dark matter and dark energy, vacuum energy, large-scale gravity modifications, and microwave background angular fluctuations. The presentation is admittedly not entirely objective but rather is given from the Russian (ITEP) perspective and is influenced by the author's personal views and biases.

Moreover, we present some perspectives, linking the models here presented with similar models, arising from different research fields.

  15. Dermatofibroma: Atypical presentations

    Directory of Open Access Journals (Sweden)

    Mousumi Roy Bandyopadhyay

    2016-01-01

    Full Text Available Dermatofibroma is a common benign fibrohistiocytic tumor and its diagnosis is easy when it presents classical clinicopathological features. However, a dermatofibroma may show a wide variety of clinicopathological variants and, therefore, the diagnosis may be difficult. The typical dermatofibroma generally occurs as a single or multiple firm reddish-brown nodules. We report here two atypical presentations of dermatofibroma - Atrophic dermatofibroma and keloidal presentation of dermatofibroma. Clinical dermal atrophy is a common phenomenon in dermatofibromas as demonstrated by the dimpling on lateral pressure. However, this feature is exaggerated in the atrophic variant of dermatofibroma. Atrophic dermatofibroma is defined by dermal atrophy of more than 50% of the lesion apart from the usual features of common dermatofibroma. The keloidal variant of dermatofibroma should not be overlooked as a simple keloid. The findings of keloidal change in dermatofibromas may support that trauma is a possible cause of dermatofibroma.

The keloidal variant of dermatofibroma should not be overlooked as a simple keloid. The findings of keloidal change in dermatofibromas may support that trauma is a possible cause of dermatofibroma.

    Full Text Available The form of the public health system in India is a three tiered pyramid-like structure consisting primary, secondary, and tertiary healthcare services. The content of India′s health system is mono-cultural and based on western bio-medicine. Authors discuss need for health sector reforms in the wake of the fact that despite huge investment, the public health system is not delivering. Today, 70% of the population pays out of pocket for even primary healthcare. Innovation is the need of the hour. The Indian government has recognized eight systems of healthcare viz., Allopathy, Ayurveda, Siddha, Swa-rigpa, Unani, Naturopathy, Homeopathy, and Yoga. Allopathy receives 97% of the national health budget, and 3% is divided amongst the remaining seven systems. At present, skewed funding and poor integration denies the public of advantage of synergy and innovations arising out of the richness of India′s Medical Heritage. Health seeking behavior studies reveal that 40-70% of the population exercise pluralistic choices and seek health services for different needs, from different systems. For emergency and surgery, Allopathy is the first choice but for chronic and common ailments and for prevention and wellness help from the other seven systems is sought. Integrative healthcare appears to be the future framework for healthcare in the 21 st century. A long-term strategy involving radical changes in medical education, research, clinical practice, public health and the legal and regulatory framework is needed, to innovate India′s public health system and make it both integrative and participatory. India can be a world leader in the new emerging field of "integrative healthcare" because we have over the last century or so assimilated and achieved a reasonable degree of competence in bio-medical and life sciences and we possess an incredibly rich and varied medical heritage of our own.

  19. Crisis and Correspondence: Style in the Nineteenth Century

    Full Text Available In his manifesto 'Das Kunstwerk der Zukunft' (1850, Richard Wagner characterised the nineteenth century as a time of crisis. Echoing Saint-Simon, he defined this crisis as a discrepancy between the spirit of the age and the actual, historical conditions. Evoking some of the most potent concepts of modern thinking—Zeitgeist, genius, and the Gesamtkunstwerk—Wagner outlined an aesthetic theory by which the artwork (including architecture simultaneously reflects and shapes its context, serving both as a mirror of its age and an agent of change.      Wagner’s seemingly paradoxical notion of art provides an apt introduction to historicist thinking. Obsessed with the idea of correspondence (or the lack of it between art and its times, nineteenth-century thinkers such as Heinrich Hübsch, Carl Bötticher and Gottfried Semper all responded to the perceived crisis. While Hübsch and Bötticher sought to alleviate the crisis by redefining this correspondence for a modern world, Semper presented a far more radical alternative. Not only did he see the current crisis as inevitable; he welcomed it as a necessary dissolution of an old order, out of which a new architecture could emerge. He thus anticipated modernists, such as Sigfried Giedion, for whom historicism was a necessary melt-down; an apocalypse, preparing for the advent of modernism. In this essay, I propose that crisis and style are intrinsically linked in modern thinking. To look closely at this coupling may throw new light not only on historicism but also on the noticeable unease with which the notion of style is treated in contemporary architectural history.

    Considerations on radiological protection always start off with discussions on concepts, principles and other basic assumptions. We are all aware of the fact that the International Commission on Radiological Protection (ICRP) is currently holding such discussions. They are useful for corporate radiological protection if they lead to rules and regulations which meet practical everyday requirements. In the topical sessions, papers have been presented on the implementation of 'basic safety standards' and corporate radiological protection in medical institutions, research institutions, technical plants and nuclear power stations. Some of these contributions were followed by discussions. In this presentation I would like to come back to some of the items raised in these discussions

  17. Environmental issues in the 21st century

    International Nuclear Information System (INIS)

    Environmental issues in the 21st century D.B. Chambers SENES Consultants Limited, Richmond Hill, Ontario, Canada Abstract. This paper provides an overview of some of the environmental challenges facing the uranium production industry in the 21st century. For many years, the linear, non-threshold (LNT) model has been regarded as a prudent hypothesis for radiation protection purposes. This paradigm has been challenged at the same time for both underestimating and overestimating the risks from ionizing radiation. The reality is that the ability of conventional epidemiology to distinguish small risks will always be limited by statistical power at low doses. In the future, there will be increased emphasis on better understanding the effects of ionizing radiation at the cellular (and sub cellular) level. The concept of 'controllable dose' has been proposed as an alternative to the International Commission on Radiological Protection's (ICRP) current approach to dose limitation. The concept is that if the most exposed individual is protected, then society as a whole is protected. A hazard ranking scale based on comparisons to natural background levels of radiation has been proposed. Adoption of a concept such as 'controllable dose' would require a parallel re-evaluation of the concepts and application of collective dose and ALARA optimization. The protection of non-human biota is an issue of considerable interest in many countries. The science in this area is rapidly evolving, as are discussions of a more philosophical nature. For example, should the focus of environmental risk assessment be the sustainability of the population or should the focus be to limit effects on a single member of the population? The future of environmental risk assessment should be of great interest to the uranium production industry. A systematic approach to risk assessment addressing the full scope of potential hazards -- environmental, human health, engineering, financial and others -- will be

  18. Global Warming and 21st Century Drying

    2014-01-01

    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 twentyfirst 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

  19. Summary of the presentations

    International Nuclear Information System (INIS)

    This part summarizes the content of the six following presentations: 1. IAEA requirements/guidance for the decommissioning safety case (Mike Bell, IAEA); 2. Safety case in an EIA context (Patrick O'SULLIVAN, The Netherlands); 3. Plant configuration and the D and D licensing process (Eugenio GIL LOPEZ and Pedro CARBONERAS, Spain); 4. Accident assessment (Ivo TRIPPUTI, Italy; Ingmar LUND, Sweden); 5. Balancing radiological and industrial risk in the safety case (Pascal DEBOODT, Belgium); 6. The safety case for safe store and dormancy periods (Paul WOOLLAM, UK). Following the six presentations, the WPDD members discussed the safety case in an open discussion led by the Topical Session Chair, Frances Taylor. The discussion was wide-ranging, and topics varied from the standards that apply to releases to the environment during safe store, to decommissioning parallels with other major processing industries and facilities (such as oil rigs). Frances Taylor steered the discussion toward addressing the questions that the WPDD Core Group had proposed for the topical session. The Chair, the Rapporteur, and some members of the group sensed that the presentations had covered such an wide variety of issues, and that the content of the presentations themselves differed so greatly, that it would be difficult to distill a position paper from the information gathered, as had been the mandate from the Core Group. In addition, the meaning of the term 'Safety Case' differed greatly among participants in the topical session. Some took the term to mean the analysis and document that the implementor provides to the regulator, describing how operations will be performed safely. Others considered the term to mean the overall safety and risk conditions inherent in a nuclear facility during operations or decommissioning. With the differences in presentations and with the meaning of the terminology remaining unclear, the WPDD participants did not reach consensus conclusions on December 5, 2001

    Full Text Available We are presenting two cases of Sirenomelia (Mermaid Syndrome, which is an extreme example of the caudal regression syndrome. It invariably presents with lower limb fusion, sacral and pelvic bony anomalies, absent external genitalia, imperforate anus, and renal agenesis or dysgenesis. There are approximately 300 cases reported in the literature, 15% of which are associated with twinning, most often monozygotic. The syndrome of caudal regression is thought to be the result of injury to the caudal mesoderm early in gestation. One of our cases survived for 12 days after birth. This new born had an unusually high anorectal anomaly in which the colon was ending at the level of mid transverse colon, fused lower limbs and genital anomalies. Ultrasound of the abdomen revealed horseshoe kidney. Colostomy was performed on day 2 of life. The second case encountered was a stillborn baby on whom an autopsy was performed.
