Energy storage technologies considered include nickel hydrogen biopolar batteries, advanced high energy rechargeable batteries, regenerative fuel cells, and advanced primary batteries. The present state-of-the-art of these space power and energy technologies is discussed along with their projections, trends and goals. A speculative future mission model is postulated which includes manned orbiting space stations, manned lunar bases, unmanned earth orbital and interplanetary spacecraft, manned interplanetary missions, military applications, and earth to space and space to space transportation systems. The various space power/energy system technologies anticipated to be operational by the early 21st century are matched to these missions.

  10. Energy Technologies for the Markets of the 21st Century

    SciTech Connect

    Schock, R

    2001-10-01

    Energy is the fuel of economic development. Yet, this is lost on the over 2 billion people in the world without access to commercial energy, most in rural areas. Meeting their needs, along with the growing needs of the population already with access, provides very large markets for energy and energy services. Studies have repeatedly shown that technology is the single most important historical driver for productivity growth. Technology is also at the heart of the goals spelled out in the World Energy Council's Statement 2000 [l]: accessibility of reliable and affordable modern energy services for all the world's inhabitants; availability of high-quality reliable delivered energy; and acceptability of energy resources produced and used in harmony with the local, regional, and global environment. With this in mind, the World Energy Council (WEC) at the time of the 17th Congress in Houston decided to identify and examine some of the energy technologies that might sustain the world in the 21st century. This effort would examine steps that might be taken to ensure that these new technologies are available to the marketplace, and what role governments and industry might play to ensure this availability. The WEC launched a major study in 1999, Energy Technologies for the 21st Century, conducted by a study group composed of international energy experts [2]. The first part of the study examined trends in public and private research, development, and demonstration (RD&D) spending over the past 15 years to determine what has been happening with the resource base for future development. Improvements in energy technologies are attained through active RD&D performed now, in advance of their implementation. Energy RD&D also provides insurance against potential impacts such as climate change, oil price shocks, and disruptions in the energy distribution system [3]. This part of the study sought to answer the questions: What is the current situation with respect to energy RD&D and

    Montemagno, Ph. D.

    2004-03-01

    Integrative technology, the merging of nanotechnology, biotechnology and informatics offers an opportunity for realizing true advances in the manner in which technology interacts with humanity. Using the power of nanotechnology to manipulate matter, that is the placing of molecules where we want, when we want, to perform functions that we want. Using the inspiration of biotechnology both to co-opt the tools of molecular manufacturing and to provide a baseline understanding of the way nature manipulates matter and information. And finally, using Informatics to create a robust framework for transforming the information implicit in molecular and larger scale interactions to engineer Complex Adaptive Systems that exhibit embedded higher-order behavior. Collectively these technologies established the basis for Integrative Technology, a new IT. The first examples of the implementation of Integrated Technology are manifested in the synthesis of a new class of smart materials. These materials have the potential to emulate much of the functionality associated with living systems such as the active transport and transformation of matter and information and, the transduction of energy into different forms. We will present the details of the technological demands and the results of efforts associated with the production of these new functional materials. Elements of the discussion will include the genetic engineering of active biological molecules into engineering building blocks, the precision assembly of these molecules into a stable, "active" material and, the promise of embedding intelligent behavior into the matrix of the assembled matter.

    A description is presented of the nature of the aerospace technology system that might be expected by the 21st century from a reasonable evolution of the current resources and capabilities. An aerospace employment outlook is provided. The years 1977 and 1978 seem to be marking the beginning of a period of stability and moderate growth in the aerospace industry. Aerospace research and development employment increased to 70,000 in 1977 and is now occupying a near-constant 18% share of the total research and development work force. The changing job environment is considered along with the future of aerospace education. It is found that one trend is toward a more interdisciplinary education. Most trend setters in engineering education recognize that the really challenging engineering problems invariably require the judicious exercise of several disciplines for their solution. Some future trends in aerospace technology are discussed. By the year 2000 space technology will have achieved major advances in four areas, including management of information, transportation, space structures, and energy.

    1997-12-31

    A major part of technological advancement has involved the development of complex infrastructure systems, including electric power generation, transmission, and distribution networks; oil and gas pipeline systems; highway and rail networks; and telecommunication networks. Dependence on these infrastructure systems renders them attractive targets for conflict in the twenty-first century. Hostile governments, domestic and international terrorists, criminals, and mentally distressed individuals will inevitably find some part of the infrastructure an easy target for theft, for making political statements, for disruption of strategic activities, or for making a nuisance. The current situation regarding the vulnerability of the infrastructure can be summarized in three major points: (1) our dependence on technology has made our infrastructure more important and vital to our everyday lives, this in turn, makes us much more vulnerable to disruption in any infrastructure system; (2) technologies available for attacking infrastructure systems have changed substantially and have become much easier to obtain and use, easy accessibility to information on how to disrupt or destroy various infrastructure components means that almost anyone can be involved in this destructive process; (3) technologies for defending infrastructure systems and preventing damage have not kept pace with the capability for destroying such systems. A brief review of these points will illustrate the significance of infrastructure and the growing dangers to its various elements.

    For several decades, semiconductor device density and performance have been doubling about every 18 months (Moore's Law). With present photolithography techniques, this rate can continue for only about another 10 years. Continued improvement will need to rely on newer technologies. Transition from the current micron range for transistor size to the nanometer range will permit Moore's Law to operate well beyond 10 years. The technologies that will enable this extension include: single-electron transistors; quantum well devices; spin transistors; and nanotechnology and molecular engineering. Continuation of Moore's Law will rely on huge capital investments for manufacture as well as on new technologies. Much will depend on the fortunes of Intel, the premier chip manufacturer, which, in turn, depend on the development of mass-market applications and volume sales for chips of higher and higher density. The technology drivers are seen by different forecasters to include video/multimedia applications, digital signal processing, and business automation. Moore's Law will affect NASA in the areas of communications and space technology by reducing size and power requirements for data processing and data fusion functions to be performed onboard spacecraft. In addition, NASA will have the opportunity to be a pioneering contributor to nanotechnology research without incurring huge expenses.

    2012-02-01

    Plants are one of the most fascinating and important groups of organisms living on Earth. They serve as the conduit of energy into the biosphere, provide food, and shape our environment. If we want to make headway in understanding how these essential organisms function and build the foundation for a more sustainable future, then we need to apply the most advanced technologies available to the study of plant life. In 2009, a committee of the National Academy highlighted the "understanding of plant growth" as one of the big challenges for society and part of a new era which they termed "new biology." The aim of this article is to identify how new technologies can and will transform plant science to address the challenges of new biology. We assess where we stand today regarding current technologies, with an emphasis on molecular and imaging technologies, and we try to address questions about where we may go in the future and whether we can get an idea of what is at and beyond the horizon.

    New technologies will unleash the huge capacity of fiber-optic cable to meet growing demands for bandwidth. Companies will continue to replace private networks with public network bandwidth-on-demand. Although asynchronous transfer mode (ATM) is the transmission technology favored by many, its penetration will be slower than anticipated. Hybrid networks - e.g., a mix of ATM, frame relay, and fast Ethernet - may predominate, both as interim and long-term solutions, based on factors such as availability, interoperability, and cost. Telecommunications equipment and services prices will decrease further due to increased supply and more competition. Explosive Internet growth will continue, requiring additional backbone transmission capacity and enhanced protocols, but it is not clear who will fund the upgrade. Within ten years, space-based constellations of satellites in Low Earth orbit (LEO) will serve mobile users employing small, low-power terminals. 'Little LEO's' will provide packet transmission services and geo-position determination. 'Big LEO's' will function as global cellular telephone networks, with some planning to offer video and interactive multimedia services. Geosynchronous satellites also are proposed for mobile voice grade links and high-bandwidth services. NASA may benefit from resulting cost reductions in components, space hardware, launch services, and telecommunications services.

    This article describes the benefits and constraints of telemedicine, focusing primarily on the field of psychiatry in the United States with the current system of healthcare. Telepsychiatry is believed to provide better access and higher-quality care to patients who need psychiatric care and cost savings to providers of such care. Telemedicine has been successfully integrated into psychiatric facilities reaching rural areas, prisons, and urban facilities. It has increased the volume of patients that physicians can reach and diagnose, as well as allowing them to treat patients with limitations in mobility. While telepsychiatry has been shown to be beneficial, this technology does have some limitations. Concerns about reimbursement, licensure, privacy, security, patient safety, and interoperability have been identified and present current challenges that providers using telepsychiatry must overcome in order to provide the most effective patient care. As more insurance companies start to reimburse for telepsychiatry treatments at the same rate as for face-to-face visits, this evolving medical field has the potential to grow exponentially.

    In the 21st Century, energy availability will be a world-wide concern. The economic health of any nation depends on an ample supply of low-cost energy to meet its electrical power, industrial, agricultural, and transportation needs. The determining forces at work in the energy dependence field are: growth, demographic patterns, economic incentives, electricity rate structure, mobility, energy production/consumption ratios, land use regulations, and air pollution rules and regulations. Renewable energy resources are becoming more viable based not only on ongoing improvements in technology, but from higher costs and greater depletion of nonrenewable resources.

  3. Emerging Technologies for the Detection of Rabies Virus: Challenges and Hopes in the 21st Century

    2009-01-01

    The diagnosis of rabies is routinely based on clinical and epidemiological information, especially when exposures are reported in rabies-endemic countries. Diagnostic tests using conventional assays that appear to be negative, even when undertaken late in the disease and despite the clinical diagnosis, have a tendency, at times, to be unreliable. These tests are rarely optimal and entirely dependent on the nature and quality of the sample supplied. In the course of the past three decades, the application of molecular biology has aided in the development of tests that result in a more rapid detection of rabies virus. These tests enable viral strain identification from clinical specimens. Currently, there are a number of molecular tests that can be used to complement conventional tests in rabies diagnosis. Indeed the challenges in the 21st century for the development of rabies diagnostics are not of a technical nature; these tests are available now. The challenges in the 21st century for diagnostic test developers are two-fold: firstly, to achieve internationally accepted validation of a test that will then lead to its acceptance by organisations globally. Secondly, the areas of the world where such tests are needed are mainly in developing regions where financial and logistical barriers prevent their implementation. Although developing countries with a poor healthcare infrastructure recognise that molecular-based diagnostic assays will be unaffordable for routine use, the cost/benefit ratio should still be measured. Adoption of rapid and affordable rabies diagnostic tests for use in developing countries highlights the importance of sharing and transferring technology through laboratory twinning between the developed and the developing countries. Importantly for developing countries, the benefit of molecular methods as tools is the capability for a differential diagnosis of human diseases that present with similar clinical symptoms.

    Radiology reading rooms have changed dramatically over the past 15 years, moving from analog-light-box-based environments to digital-display-based environments. Most of the focus in the early stages of this transition was on the technology, but it soon became obvious that it was not possible or even prudent to consider the technology without considering radiologists. The information being presented to radiologists in digital reading rooms is in many ways very different from that presented on traditional film. On one hand, the digital workstation display medium itself is very different from traditional film images hung on light boxes. On the other hand, without large-area light boxes, images such as those from computed tomography (CT) can no longer be displayed all at once in a series of film sheets. The digital world also introduces the possibility of manipulating image data in ways that were never possible with analog film. Not only can radiologists manipulate image data with various image-processing tools, but also, computers can analyze images and provide even more information to incorporate into the interpretation process. As a consequence of these differences, it has been necessary to focus attention on radiologists to discover ways to optimize the digital reading environment with respect to the human visual system and the way the eye-brain system processes information. This article reviews some of the important perceptual issues that have arisen in the digital reading rooms of the 21st century.

  7. Electricity technology roadmap: meeting the critical challenges of the 21st century: 2003 summary and synthesis

    SciTech Connect

    2003-07-01

    The Electricity Technology Roadmap represents a collective vision of the opportunities for electricity to serve society in the 21st century through advances in science and technology. It is intended to be periodically updated. The Electricity Technology Roadmap initiative began in 1997. Although it was spearheaded by EPRI, over 200 organizations contributed to an initial report in 1999. It was organized around five Destinations that are critical milestones on the path toward achieving a sustainable global energy economy by 2050. These Destinations are: (1) Strengthening the Power Delivery Infrastructure, (2) Enabling the Digital Society, (3) Boosting Economic Productivity and Prosperity, (4) Resolving the Energy/Environment Conflict, and (5) Managing the Global Sustainability Challenge. This 2003 Roadmap edition begins the more detailed planning needed to 'build the road' to reach these five Destinations. A formal effort to expand and extend the Roadmap began in early 2002. Teams worked on 14 broad 'Limiting Challenges' that require technical breakthroughs to meet society's requirements for electricity and electricity-based services in the new century. This work included laying out specific research and development programs to address the 'critical capability gaps' in knowledge and technology for each of the Limiting Challenges. This report is a summary and synthesis of the research described by the various Roadmap teams. It draws out the major conclusions and puts forward a set of priorities and recommendations for accelerating electricity-based R&D in the United States and around the world. It also links to a number of EPRI overview reports of strategic significance, such as the 2003 report titled 'Electricity Sector Framework for the Future,' which is also available on www.epri.com.

  8. Energy Technologies for the 21st Century-The Roles of Renewable Energy

    SciTech Connect

    Schock, R N

    2005-07-29

    Renewable energy sources, originating for the most part from the sun's radiant energy, are ubiquitous, long-lived, essentially free of carbon emissions, and have the potential to contribute significantly to mounting energy needs of the globe. In terms of percentage increase in installed capacity, renewable energy collectively is the fastest growing energy source. Even assuming that the developing world raises its standard of living considerably, the technical potential of renewable energies is more than enough to meet annual global needs several times over a century from now. Realizing even some of this potential involves overcoming obstacles in generation costs, proximity to markets, and in many cases intermittency, as well as others. From the perspective of work on a wide range of energy technologies by both the World Energy Council and the Intergovernmental Panel on Climate Change, the potential, timing, and investment costs for renewable energy technologies in the 21st century have become clearer. The marketplace, based on cost and performance, will determine which technologies are commercialized along with government policies that at a minimum do not hinder their introduction, and--at a maximum--may encourage more rapid and successful introduction. A wide range of possible scenarios (34) based on factors that include energy availability, demographics, economic development, competition, environmental constraints, and most importantly technical learning, place some constraints on the range of possible energy requirements. Most scenarios indicate that renewable energy in total is likely to be as much as half the world's supply in 100 years, but most of that growth is expected in the period 50 to 100 years from now--if critical advancements and investments are made over the next 50 years.

    1998-01-01

    This article discusses the needs in developing countries for simple and inexpensive technological devices to improve communications and transportation and to reduce time and energy spent on housework. Manufacturers in the developed world continue to export expensive technological products that ignore the lack of access to electricity among a large consumer population. Individuals and organizations can help developing country women by engaging in conversations with their counterparts and determining the nature and extent of assistance that is needed. Products, such as old computers, spare parts, and computer books, can be donated to organizations, such as the YWCA, which provide training to girls and women. Industry can produce and market technologically appropriate implements and appliances. Individuals and women's groups can lobby industrialists and manufacturers for initiatives that improve living conditions for millions in developing countries. Groups can mobilize financial resources for local and international projects. Partnerships can be formed between cities, local universities, nonprofit organizations, individual school classes, or individuals. Governments need to ensure that the educational system is producing skilled workers and to modify imported technologies for local development. In the race to the 21st century, there is a need for deliberate social action to make technology accessible to women, men, and children in remote rural communities in developing countries. The gain for women in developing countries would be substantially reduced time and energy expended in daily chores. In developing countries, most of the agricultural and domestic work is carried out by women. These women are not even at the starting gate, while women in developed countries are way ahead in the race for modernization and technological development.

  10. Perspectives on scientific and technological literacy in Tonga: Moving forward in the 21st century

    NASA Astrophysics Data System (ADS)

    Palefau, Tevita Hala

    Tonga has undergone complex changes in the last three decades. Disturbing numbers of young Tongans have inadequate knowledge in traditional science and technology, ill equipped to work in, contribute to and profit from our society. In short, they lack sufficient background knowledge to acquire the training, skills and understanding that are needed in the 21st Century. The purpose of this research is to assist the formulation of national science and technology curriculum. Hence, views of life in Tonga and opinions about Tonga's needs held by three stakeholder groups (traditional, workplaces, public) were paramount in this study. How these stakeholders see Tonga in terms of science and technology needs will contribute substantially to the Ministry of Education's decisions for this century. Based on critical evaluation of international literature and how scientific and technological literacy (STL) is crucial to Tongan society, a model 'TAP-STL' is established as study framework: 'TAP' for ṯraditional, a&barbelow;cademic and p&barbelow;ublic STL, to promote national development. This qualitative case study employs an interview method to collect data from twelve knowledgeable participants selected by reputational sampling from across the kingdom. By exploring their understanding of STL requirements, the study sought to identify any shortfall between the science and technology provided in school and that needed for maintenance of traditional culture, effective participation in Tonga's workplaces and public understanding. The study produced findings under these categories: understanding of traditional knowledge and skills needed to preserve Tongan cultural identity; understanding needed for fishing, handicrafts and everyday maintenance, together with essential health knowledge and skills; and required understanding of public information campaigns related to health, domestic goods, drugs and environment that contribute to responsible citizenship.

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.

  7. Antiparasitic DNA vaccines in 21st century.

    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.

    NASA Technical Reports Server (NTRS)

    Mccarthy, J. F., Jr.

    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.

    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.

  12. Food safety in the 21st century.

    Käferstein, F.; Abdussalam, M.

    1999-01-01

    The global importance of food safety is not fully appreciated by many public health authorities despite a constant increase in the prevalence of foodborne illness. Numerous devastating outbreaks of salmonellosis, cholera, enterohaemorrhagic Escherichia coli infections, hepatitis A and other diseases have occurred in both industrialized and developing countries. In addition, many of the re-emerging or newly recognized pathogens are foodborne or have the potential of being transmitted by food and/or drinking water. More foodborne pathogens can be expected because of changing production methods, processes, practices and habits. During the early 21st century, foodborne diseases can be expected to increase, especially in developing countries, in part because of environmental and demographic changes. These vary from climatic changes, changes in microbial and other ecological systems, to decreasing freshwater supplies. However, an even greater challenge to food safety will come from changes resulting directly in degradation of sanitation and the immediate human environment. These include the increased age of human populations, unplanned urbanization and migration and mass production of food due to population growth and changed food habits. Mass tourism and the huge international trade in food and feed is causing food and feedborne pathogens to spread transnationally. As new toxic agents are identified and new toxic effects recognized, the health and trade consequences of toxic chemicals in food will also have global implications. Meeting the huge challenge of food safety in the 21st century will require the application of new methods to identify, monitor and assess foodborne hazards. Both traditional and new technologies for assuring food safety should be improved and fully exploited. This needs to be done through legislative measures where suitable, but with much greater reliance on voluntary compliance and education of consumers and professional food handlers. This will

    2009-07-02

    In this paper I argue for the need for a strong Science and Technology program in the Nuclear Weapons Complex as the basis for maintaining a credible deterrence capability. The current Nuclear Posture Review establishes a New Triad as the basis for the United States deterrence strategy in a changing security environment. A predictive science capability is at the core of a credible National Nuclear Weapons program in the 21st Century. In absence of nuclear testing, the certification of our current Nuclear Weapons relies on predictive simulations and quantification of the associated simulation uncertainties. In addition, a robust nuclear infrastructure needs an active research and development program that considers all the required nuclear scenarios, including new configurations for which there is no nuclear test data. This paper also considers alternative positions to the need for a Science and Technology program in the Nuclear Weapons complex.

The many threats to future survival of this planet's sensitive ecosystem are also discussed in relation to the technoecological harmony that might be achievable due to the extreme demands that are naturally imposed on the development of (civilian/human) space technology. The human attempt to inhabit the inner solar system (the Moon, Mars, etc.) is proposed as the ultimate and most appropriate technology driver for the myriad of socioeconomic, ecological, and technological needs that will accompany 21st Century Earth societies.

  6. Biofabrication: a 21st century manufacturing paradigm.

    PubMed

    Mironov, V; Trusk, T; Kasyanov, V; Little, S; Swaja, R; Markwald, R

    2009-06-01

    Biofabrication can be defined as the production of complex living and non-living biological products from raw materials such as living cells, molecules, extracellular matrices, and biomaterials. Cell and developmental biology, biomaterials science, and mechanical engineering are the main disciplines contributing to the emergence of biofabrication technology. The industrial potential of biofabrication technology is far beyond the traditional medically oriented tissue engineering and organ printing and, in the short term, it is essential for developing potentially highly predictive human cell- and tissue-based technologies for drug discovery, drug toxicity, environmental toxicology assays, and complex in vitro models of human development and diseases. In the long term, biofabrication can also contribute to the development of novel biotechnologies for sustainable energy production in the future biofuel industry and dramatically transform traditional animal-based agriculture by inventing 'animal-free' food, leather, and fur products. Thus, the broad spectrum of potential applications and rapidly growing arsenal of biofabrication methods strongly suggests that biofabrication can become a dominant technological platform and new paradigm for 21st century manufacturing. The main objectives of this review are defining biofabrication, outlining the most essential disciplines critical for emergence of this field, analysis of the evolving arsenal of biofabrication technologies and their potential practical applications, as well as a discussion of the common challenges being faced by biofabrication technologies, and the necessary conditions for the development of a global biofabrication research community and commercially successful biofabrication industry.

    In the last century, vaccination has been the most effective medical intervention to reduce death and morbidity caused by infectious diseases. It is believed that vaccines save at least 2–3 million lives per year worldwide. Smallpox has been eradicated and polio has almost disappeared worldwide through global vaccine campaigns. Most of the viral and bacterial infections that traditionally affected children have been drastically reduced thanks to national immunization programs in developed countries. However, many diseases are not yet preventable by vaccination, and vaccines have not been fully exploited for target populations such as elderly and pregnant women. This review focuses on the state of the art of recent clinical trials of vaccines for major unmet medical needs such as HIV, malaria, TB, and cancer. In addition, we describe the innovative technologies currently used in vaccine research and development including adjuvants, vectors, nucleic acid vaccines, and structure-based antigen design. The hope is that thanks to these technologies, more diseases will be addressed in the 21st century by novel preventative and therapeutic vaccines. PMID:24803000

    Gallbladder cancer (GBC) is an uncommon disease in the majority of the world despite being the most common and aggressive malignancy of the biliary tree. Early diagnosis is essential for improved prognosis; however, indolent and nonspecific clinical presentations with a paucity of pathognomonic/predictive radiological features often preclude accurate identification of GBC at an early stage. As such, GBC remains a highly lethal disease, with only 10% of all patients presenting at a stage amenable to surgical resection. Among this select population, continued improvements in survival during the 21st century are attributable to aggressive radical surgery with improved surgical techniques. This paper reviews the current available literature of the 21st century on PubMed and Medline to provide a detailed summary of the epidemiology and risk factors, pathogenesis, clinical presentation, radiology, pathology, management, and prognosis of GBC.

    The noise, gaseous and particulate pollution inherent in 19th and 20th century transportation must be eliminated from the city of the 21st century. If cities are to achieve their full potential as economic and cultural centers they must possess superior transportation systems. Ultra-silent, energy stingy, non-polluting maglevs can furnish the passenger and freight transportation system that the coming millennium will demand. Maglev floats railroad-like cars on a magnetic field a few inches above an elevated guideway. The cars can move at any convenient speed up to 300 mph. Yet, maglev produces less noise than a well muffled automobile, no vibration and no pollution.

  5. Transformations in Air Transportation Systems For the 21st Century

    Holmes, Bruce J.

    2004-01-01

    Globally, our transportation systems face increasingly discomforting realities: certain of the legacy air and ground infrastructures of the 20th century will not satisfy our 21st century mobility needs. The consequence of inaction is diminished quality of life and economic opportunity for those nations unable to transform from the 20th to 21st century systems. Clearly, new thinking is required regarding business models that cater to consumers value of time, airspace architectures that enable those new business models, and technology strategies for innovating at the system-of-networks level. This lecture proposes a structured way of thinking about transformation from the legacy systems of the 20th century toward new systems for the 21st century. The comparison and contrast between the legacy systems of the 20th century and the transformed systems of the 21st century provides insights into the structure of transformation of air transportation. Where the legacy systems tend to be analog (versus digital), centralized (versus distributed), and scheduled (versus on-demand) for example, transformed 21st century systems become capable of scalability through technological, business, and policy innovations. Where air mobility in our legacy systems of the 20th century brought economic opportunity and quality of life to large service markets, transformed air mobility of the 21st century becomes more equitable available to ever-thinner and widely distributed populations. Several technological developments in the traditional aircraft disciplines as well as in communication, navigation, surveillance and information systems create new foundations for 21st thinking about air transportation. One of the technological developments of importance arises from complexity science and modern network theory. Scale-free (i.e., scalable) networks represent a promising concept space for modeling airspace system architectures, and for assessing network performance in terms of robustness

  6. Enhancing student engagement through the affordances of mobile technology: a 21st century learning perspective on Realistic Mathematics Education

    Several recent curriculum reforms aim to address the shortfalls traditionally associated with mathematics education through increased emphasis on higher-order-thinking and collaborative skills. Some stakeholders, such as the US National Council of Teachers of Mathematics and the UK Joint Mathematical Council, advocate harnessing the affordances of digital technology in conjunction with social constructivist pedagogies, contextual scenarios, and/or approaches aligned with Realistic Mathematics Education (RME). However, it can be difficult to create technology-mediated, collaborative and contextual activities within a conventional classroom setting. This paper explores how a combination of a transformative, mobile technology-mediated approach, RME, and a particular model of 21st century learning facilitates the development of mathematics learning activities with the potential to increase student engagement and confidence. An explanatory case study with multiple embedded units and a pre-experimental design was conducted with a total of 54 students in 3 schools over 25 hours of class time. Results from student interviews, along with pre-test/post-test analysis of questionnaires, suggest that the approach has the potential to increase student engagement with, and confidence in, mathematics. This paper expands on these results, proposing connections between aspects of the activity design and their impact on student attitudes and behaviours.

    The precious metal gold can be found at high concentration in tailings dumps and waste rock piles at many mining locations around the world. Conventional technology is generally unable to economically recover this residual gold, and, as a result, the potential resource is wasted, presenting environmental risk to the wider ecosystem through particulate and dissolved metal leaching and erosion. For the past 14 years, the idea of gold phytomining to recover this gold resource has been researched by various scientific groups worldwide. A number of plant species have been tested under laboratory, greenhouse, and field conditions to determine their potential for use in the phytoextraction of gold. This paper presents a review of reported gold phytomining trials developed in the laboratory, the greenhouse under soil and hydroponic conditions, as well as in the field, between 1998 and 2011. A summary economic assessment for gold phytomining in Mexico is also presented. Mexico is an example of a developing country with a long history of gold mining that has a large resource of sites that might be suitable to gold phytomining. The technology remains limited by certain environmental and plant physiology factors. However, the increase in the market price for gold during the first decade of the 21st century and into 2011, and advances recorded for the gold concentration and biomass yield of a range of plant species, suggest that gold phytomining might be an economically viable technology.

  8. Managing Reliability in the 21st Century

    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.

  17. Improving clinical practice guidelines for the 21st century. Attitudinal barriers and not technology are the main challenges.

    PubMed

    Browman, G P

    2000-01-01

    Through the use of three scenarios, this paper presents the challenges for clinical practice guidelines in the 21st century. Such challenges relate to technological developments to improve the efficiency and pace of the development process, to ensure that clinical practice guidelines are kept up to date, and to facilitate implementation of guidelines in the clinical setting. To improve and ensure the validity of the content of clinical practice guidelines, we need to address the important problem of publication bias, for which researchers, granting agencies, industry, and journal editors share responsibility. This means insisting on registration of trials at their inception, and incentives backed up by rules for funding and peer review publication that would promote behaviors to avoid publication bias. The more difficult challenges for clinical practice guidelines relate to what are referred to as attitudinal factors. To achieve optimal efficiencies in development and maintenance of clinical practice guidelines, we need to promote cooperation among various information resource providers internationally and to stress partnership over leadership. Finally, there need to be reconciliation of the different stakeholder perspectives of the value and purpose of clinical practice guidelines so that they are used appropriately as aids to decision making and are not abused as tools for controlling clinical practice.

    2011-01-01

    Background The Vivian Bullwinkel Oration honours the life and work of an extraordinary nurse. Given her story and that of her World War II colleagues, the topic of nursing heroism in the 21st century could not be more germane. Discussion Is heroism a legitimate part of nursing, or are nurses simply 'just doing their job' even when facing extreme personal danger? In this paper I explore the place and relevance of heroism in contemporary nursing. I propose that nursing heroism deserves a broader appreciation and that within the term lie many hidden, 'unsung' or 'unrecorded' heroisms. I also challenge the critiques of heroism that would condemn it as part of a 'militarisation' of nursing. Finally, I argue that nursing needs to be more open in celebrating our heroes and the transformative power of nursing achievements. Summary The language of heroism may sound quaint by 21st Century standards but nursing heroism is alive and well in the best of our contemporary nursing ethos and practice. PMID:21324152

    Early science fiction envisioned the future of drug delivery as targeted micrometer-scale submarines and "cyborg" body parts. Here we describe the progression of the field toward technologies that are now beginning to capture aspects of this early vision. Specifically, we focus on the two most prominent types of systems in drug delivery: the intravascular micro/nano drug carriers for delivery to the site of pathology and drug-loaded implantable devices that facilitate release with the predefined kinetics or in response to a specific cue. We discuss the unmet clinical needs that inspire these designs, the physiological factors that pose difficult challenges for their realization, and viable technologies that promise robust solutions. We also offer a perspective on where drug delivery may be in the next 50 years based on expected advances in material engineering and in the context of future diagnostics.

    SciTech Connect

    1997-12-31

    Agricultural managers have for decades taken advantage of new technologies, including information technologies, that enabled better management decision making and improved economic efficiency of operations. The extent and rate of change now occurring in the development of information technologies have opened the way for significant change in crop production management and agricultural decision making. This vision is reflected in the concept of precision agriculture. Precision agriculture is a phrase that captures the imagination of many concerned with the production of food, feed, and fiber. The concepts embodied in precision agriculture offer the promise of increasing productivity while decreasing production costs and minimizing environmental impacts. Precision agriculture conjures up images of farmers overcoming the elements with computerized machinery that is precisely controlled via satellites and local sensors and using planning software that accurately predicts crop development. This image has been called the future of agriculture. Such high-tech images are engaging. Precision agriculture, however, is in early and rapidly changing phases of innovation. Techniques and practices not anticipated by the committee will likely become common in the future, and some techniques and practices thought to hold high promise today may turn out to be less desirable than anticipated. This report defines precision agriculture as a management strategy that uses information technologies to bring data from multiple sources to bear on decisions associated with crop production. Precision agriculture has three components: capture of data at an appropriate scale and frequency, interpretation and analysis of that data, and implementation of a management response at an appropriate scale and time. The most significant impact of precision agriculture is likely to be on how management decisions address spatial and temporal variability in crop production systems.

  5. Riser technology for deepwater scientific drilling in the 21st century

    SciTech Connect

    Sparks, C.P.

    1995-12-31

    Scientific drilling and coring in the deep ocean is at present carried out in riserless mode using oil industry type equipment. Penetration, hole stability and core recovery could be greatly improved if riser technology were available to allow the use of mud, and if mining technology could be adapted for use in deep water. This paper explores the possibility of using a slimline riser (9 5/8 inch O.D.) for scientific drilling and coring in 4,000 m of water. The mode of operation is described and preliminary analyses of such a riser made from different materials (steel, titanium, aluminum and composite) are presented. In 4,000 m of water it is shown that one of the principal problems is the axial dynamic behavior of the riser in the hung-off mode. Analyses show that, in such conditions, slimline risers have greatly improved behavior compared to oil industry risers. They are also much simpler, and are an order of magnitude less massive. Mining drilling systems (3 1/2 inch O.D.) with diamond bits show great promise for improving core recovery in fractured basalt. They can be deployed through a standard drill string (5 inch O.D.) which then acts as a mini-riser. The paper shows that one of the keys to their use is a clear understanding of the axial dynamic behavior of the mini-riser in the connected mode (connected to the seabed).

    The complement system has been studied for about 120 years. Progress in defining this large and complex system has been dependent on the research technologies available, but since the introduction of protein chromatography, electrophoresis, and antibody-based assay methods in the 1950s and 60s, and sequencing of proteins and DNA in the 70s and 80s, there has been very rapid accumulation of data. With more recent improvements in 3D structure determination (nmr and X-ray crystallography), the structures of most of the complement proteins have now been solved. Complement research since 1990 has been greatly stimulated by the discoveries of the multiple proteins in the lectin pathway, the strong association of Factor H, C3, Factor B allelic variants with adult macular degeneration and atypical haemolytic uremic syndrome, and the introduction of the anti-C5 monoclonal antibody as a therapy for paroxysmal nocturnal hemoglobinuria and atypical haemolytic uremic syndrome. Potential new roles for complement in tissue development and the search for novel therapeutics suggest a very active future for complement research. PMID:27371361

    The blood-brain barrier (BBB) maintains the brain homeostasis and dynamically responds to events associated with systemic and/or rheological impairments (e.g., inflammation, ischemia) including the exposure to harmful xenobiotics. Thus, understanding the BBB physiology is crucial for the resolution of major central nervous system CNS) disorders challenging both health care providers and the pharmaceutical industry. These challenges include drug delivery to the brain, neurological disorders, toxicological studies, and biodefense. Studies aimed at advancing our understanding of CNS diseases and promoting the development of more effective therapeutics are primarily performed in laboratory animals. However, there are major hindering factors inherent to in vivo studies such as cost, limited throughput and translational significance to humans. These factors promoted the development of alternative in vitro strategies for studying the physiology and pathophysiology of the BBB in relation to brain disorders as well as screening tools to aid in the development of novel CNS drugs. Herein, we provide a detailed review including pros and cons of current and prospective technologies for modelling the BBB in vitro including ex situ, cell based and computational (in silico) models. A special section is dedicated to microfluidic systems including micro-BBB, BBB-on-a-chip, Neurovascular Unit-on-a-Chip and Synthetic Microvasculature Blood-Brain Barrier. PMID:25098812

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.

    Every economic institution finds itself caught on the horns of a dilemma: Competing sets of values strike a conflict between social good and economic wealth, regardless of whether organizations articulate it. The struggle in U.S. health care, however, is both more acute and poignant. On the one hand, ethical and cultural values require societal commitments to the well-being of the individual. Who among us would want to refuse help to someone sick or injured? On the other hand, market forces require an economic accounting of health care. Social trends emphasize a mission to provide care for all, while managed care promotes the industry's fidelity to a balanced ledger. U.S. health care is thus defined by paradox. The nation spends more than $1.3 trillion annually on health care--a national line-item larger than the economies of all other nations except two (Germany and Japan). A new study by the Health Care Financing Administration warns that health care spending may nearly double to $2.1 trillion by 2007. Yet the industry is perceived to be too "resource-constrained" to assure health care services for all citizens. This poses a key question: Are there too few resources, or are we simply not allocating them in the best ways possible? Health care's "double bottom line"--social and economic accountability--typifies the social and economic milieu of health care as the final pages turn on the 20th Century. And, it is this duality that forms the underlying theme for the landmark study--Leadership for a Healthy 21st Century--conducted over the course of the past year by Arthur Andersen and The Healthcare Forum Foundation, with primary research support from DYG, Inc. and Baruch Lev, professor at the Stern School of Business, New York University. The study was designed to investigate a new economic model emerging in the information economy and its impact on health care; the evolving values of consumers in relation to business, health and health care; and the values of

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

    NASA Astrophysics Data System (ADS)

    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.

    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.

    Ongoing NASA-funded and privately funded studies continue to indicate that an opportunity exists for a second generation supersonic commercial airliner, or High-Speed Civil Transport (HSCT), to become a key part of the 21st century international air transportation system. Long distance air travel is projected to increase at about 5 percent per annum over the next two decades. This projection suggests that by the year 2015, more than 600,000 passengers per day will be traveling long distances, predominantly over water. These routes would be among the most desirable for an HSCT as part of the international air transportation system. Beyond the year 2000, this portion of the air transportation market is projected to be the fastest growing segment.

    When Watson and Crick proposed the double helix model for DNA structure in a 2 page Nature article in 1953, no one could have predicted the enormous impact this finding would have on the study of human disease. Over the last decade in particular, major advances have been made in our understanding of both normal biological processes and basic molecular mechanisms underlying a variety of medical diseases. Knowledge obtained from basic cellular, molecular and genetic studies has enabled the development of strategies for the modification, prevention and potential cure of human diseases. This brief overview focuses on the enormous impact molecular studies have had on various aspects of medicine. The inherited cardiac disorder hypertrophic cardiomyopathy is used here as a model to illustrate how molecular studies have not only redefined 'gold standards' for diagnosis, but have also influenced management approaches, increased our understanding of fundamental disease-causing mechanisms and identified potential targets for therapeutic intervention. The near-completion of the Human Genome Project, which identifies the 3.2 billion base pairs that comprise the human genome (the so-called 'Book of Life'), has exponentially heightened the focus on the importance of molecular studies and how such studies will impact on various aspects of medicine in the 21st century.

    Chiropractic theory and development is briefly explored and compared with contemporary medical theory. Theoretical and philosophical assumptions in chiropractic, this writer predicts, may be challenged and altered in the 21st century. Technological advances and a slow trend in chiropractic toward a more scientific basis may result in improved theory, practice, and utilization in the next century. In order for such advances to occur, however, the profession must change some deeply rooted attitudes regarding scientific research and practice, adopt new attitudes regarding the need for clinical research, and ultimately become consumers of chiropractic research and of chiropractic techniques that have been subject to research.

    Lithium is an important industrial compound and the principal component of high energy-density batteries. Because it is the lightest solid element, these batteries are widely used in consumer electronics and are expected to be the basis for battery electric vehicles (BEVs), hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) for the 21st century. In view of the large incremental demand for lithium that will result from expanded use of various types of EVs, long-term estimates of lithium demand and supply are advisable. For GDP growth rates of 2 to 3% and battery recycling rates of 90 to 100%, total demand for lithium for all markets is expected to be a maximum of 19.6 million tonnes through 2100. This includes 3.2 million tonnes for industrial compounds, 3.6 million tonnes for consumer electronics, and 12.8 million tonnes for EVs. Lithium-bearing mineral deposits that might supply this demand contain an estimated resource of approximately 39 million tonnes, although many of these deposits have not been adequately evaluated. These lithium-bearing mineral deposits are of two main types, non-marine playa-brine deposits and igneous deposits. Playa-brine deposits have the greatest immediate resource potential (estimated at 66% of global resources) and include the Salar de Atacama (Chile), the source of almost half of current world lithium production, as well as Zabuye (China/Tibet) and Hombre Muerto (Argentina). Additional important playa-brine lithium resources include Rincon (Argentina), Qaidam (China), Silver Peak (USA) and Uyuni (Bolivia), which together account for about 35% of the estimated global lithium resource. Information on the size and continuity of brine-bearing aquifers in many of these deposits is limited, and differences in chemical composition of brines from deposit to deposit require different extraction processes and yield different product mixes of lithium, boron, potassium and other elements. Numerous other brines in playas

    Assume no previous theories about genetics and evolution. What conclusions would we draw from molecular data (e.g. genome sequences)? We start from basic principles of cellular information processing: cells behave cognitively using signal transduction networks; signal transduction involves weak noncovalent interactions; allosteric properties of biomolecules; multivalent storage of information in DNA sequences and nucleoprotein complexes; inertness of naked DNA. Genome informatics thus requires formation of nucleoprotein complexes. Complex formation requires generic repeated signals in the DNA; repetition also permits cooperativity to stabilize weak interactions. DNA is a functional structural component of nucleoprotein complexes, not a passive data tape. Specificity in DNA nucleoprotein complex formation involves combining multiple generic signals and/or sequence recognition by small RNAs. Novel combinations of generic signals and coding sequences arise in genomes by iteration and rearrangement. Cells possess natural genetic engineering functions that actively restructure DNA molecules. These internal DNA remodeling functions act cognitively in response to internal and external inputs. They operate non-randomly with respect to (1) the types of new structures produced and (2) the regions of the genome modified. Whole genome sequence data increasingly documents the historical role of natural genetic engineering in evolutionary changes. Basic principles of cellular molecular biology and DNA function lead to a complex interactive systems view of genome organization. This view incorporates different DNA components found in sequenced genomes. Regulated cellular natural genetic engineering functions permit genomes to serve as Read-Write information storage systems, not just Read-Only memories subject to accidental change. These 21st Century conclusions are most compatible with a systems engineering view of the evolutionary process.

    Geoscience knowledge and skills play new roles in the workforce as our society addresses the challenges of living safely and sustainably on Earth. As a result, we expect a wider range of future career opportunities for students with education in the geosciences and related fields. A workshop offered by the InTeGrate STEP Center on 'Geoscience and the 21st Century Workforce' brought together representatives from 24 programs with a substantial geoscience component, representatives from different employment sectors, and workforce scholars to explore the intersections between geoscience education and employment. As has been reported elsewhere, employment in energy, environmental and extractive sectors for geoscientists with core geology, quantitative and communication skills is expected to be robust over the next decade as demand for resources grow and a significant part of the current workforce retires. Relatively little is known about employment opportunities in emerging areas such as green energy or sustainability consulting. Employers at the workshop from all sectors are seeking the combination of strong technical, quantitative, communication, time management, and critical thinking skills. The specific technical skills are highly specific to the employer and employment needs. Thus there is not a single answer to the question 'What skills make a student employable?'. Employers at this workshop emphasized the value of data analysis, quantitative, and problem solving skills over broad awareness of policy issues. Employers value the ability to articulate an appropriate, effective, creative solution to problems. Employers are also very interested in enthusiasm and drive. Participants felt that the learning outcomes that their programs have in place were in line with the needs expressed by employers. Preparing students for the workforce requires attention to professional skills, as well as to the skills needed to identify career pathways and land a job. This critical

    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

    In most areas of life, Americans enjoy the ease and convenience offered by advances in technology, communications, and transportation. Every day we experience the 21st-century model of America, which is one of effectiveness, accuracy, speed, flexibility, efficiency, lower cost, more choices, and greater achievement. We can shop online, compare prices for goods and services, and when decisions need to be made, we have access to a wide array of information sources to assist in making those decisions. In short, Americans enjoy great latitude in our power to determine what is best for us. This is not, however, the case when it comes to health and healthcare. In our current healthcare system, individuals are dependent on a structure that has resisted the natural progress and modernization achieved by market-oriented, 21st-century industries. The information age has been leaving health behind. Although it is the nature of a science- and technology-based entrepreneurial free market to provide more choices of higher quality at lower cost, in the healthcare sector, prices continue to rise, quality is inconsistent, and individuals lack the information, incentives, and power to make choices.

    n 2012, the National Cancer Institute (NCI) engaged the scientific community to provide a vision for cancer epidemiology in the 21st century. Eight overarching thematic recommendations, with proposed corresponding actions for consideration by funding agencies, professional societies, and the research community emerged from the collective intellectual discourse. The themes are (i) extending the reach of epidemiology beyond discovery and etiologic research to include multilevel analysis, intervention evaluation, implementation, and outcomes research; (ii) transforming the practice of epidemiology by moving toward more access and sharing of protocols, data, metadata, and specimens to foster collaboration, to ensure reproducibility and replication, and accelerate translation; (iii) expanding cohort studies to collect exposure, clinical, and other information across the life course and examining multiple health-related endpoints; (iv) developing and validating reliable methods and technologies to quantify exposures and outcomes on a massive scale, and to assess concomitantly the role of multiple factors in complex diseases; (v) integrating big data science into the practice of epidemiology; (vi) expanding knowledge integration to drive research, policy, and practice; (vii) transforming training of 21st century epidemiologists to address interdisciplinary and translational research; and (viii) optimizing the use of resources and infrastructure for epidemiologic studies. These recommendations can transform cancer epidemiology and the field of epidemiology, in general, by enhancing transparency, interdisciplinary collaboration, and strategic applications of new technologies. They should lay a strong scientific foundation for accelerated translation of scientific discoveries into individual and population health benefits.

  1. Identifying 21st Century STEM Competencies Using Workplace Data

    NASA Astrophysics Data System (ADS)

    Jang, Hyewon

    2016-04-01

    Gaps between science, technology, engineering, and mathematics (STEM) education and required workplace skills have been identified in industry, academia, and government. Educators acknowledge the need to reform STEM education to better prepare students for their future careers. We pursue this growing interest in the skills needed for STEM disciplines and ask whether frameworks for 21st century skills and engineering education cover all of important STEM competencies. In this study, we identify important STEM competencies and evaluate the relevance of current frameworks applied in education using the standardized job-specific database operated and maintained by the US Department of Labor. Our analysis of the importance of 109 skills, types of knowledge and work activities, revealed 18 skills, seven categories of knowledge, and 27 work activities important for STEM workers. We investigate the perspectives of STEM and non-STEM job incumbents, comparing the importance of each skill, knowledge, and work activity for the two groups. We aimed to condense dimensions of the 52 key areas by categorizing them according to the Katz and Kahn (1978) framework and testing for inter-rater reliability. Our findings show frameworks for 21st century skills and engineering education do not encompass all important STEM competencies. Implications for STEM education programs are discussed, including how they can bridge gaps between education and important workplace competencies.

    The concept is related of computer driven multimedia to the NASA Scientific and Technical Information Program (STIP). Multimedia is defined here as computer integration and output of text, animation, audio, video, and graphics. Multimedia is the stage of computer based information that allows access to experience. The concepts are also drawn in of hypermedia, intermedia, interactive multimedia, hypertext, imaging, cyberspace, and virtual reality. Examples of these technology developments are given for NASA, private industry, and academia. Examples of concurrent technology developments and implementations are given to show how these technologies, along with multimedia, have put us at the threshold of the 21st century. The STI Program sees multimedia as an opportunity for revolutionizing the way STI is managed.

  6. Informing 21st-Century Risk Assessments with 21st-Century Science.

    PubMed

    Birnbaum, Linda S; Burke, Thomas A; Jones, James J

    2016-04-01

    Understanding and preventing adverse impacts from chemicals in the environment is fundamental to protecting public health, and chemical risk assessments are used to inform public health decisions in the United States and around the world. Traditional chemical risk assessments focus on health effects of environmental contaminants on a chemical-by-chemical basis, largely based on data from animal models using exposures that are typically higher than those experienced by humans. Results from environmental epidemiology studies sometimes show effects that are not observed in animal studies at human exposure levels that are lower than those used in animal studies. In addition, new approaches such as Toxicology in the 21st Century (Tox21) and exposure forecasting (ExpoCast) are generating mechanistic data that provide broad coverage of chemical space, chemical mixtures, and potential associated health outcomes, along with improved exposure estimates. It is becoming clear that risk assessments in the future will need to use the full range of available mechanistic, animal, and human data to integrate multiple types of data and to consider nontraditional health outcomes and end points. This perspective was developed at the "Strengthening the Scientific Basis of Chemical Safety Assessments" workshop, which was cosponsored by the U.S. Environmental Protection Agency and the National Institute of Environmental Health Sciences, where gaps between the emerging science and traditional chemical risk assessments were explored, and approaches for bridging the gaps were considered.

  11. Civilian Power from Space in the Early 21st Century

    SciTech Connect

    Hyde, R; Ishikawa, M; Wood, L

    2003-06-01

    If power beamed from space is to be become widely used on Earth in the first half of the 21St century, several thus-far-persistent impediments must be obviated, including threshold effects and problematic aspects of cost, availability, reliability, hazards and environmental impacts. We sketch a generally-applicable route to doing so, noting key enabling technologies and practical features. Likely-essential features of any successful strategy include vigorous, systematic leveraging of all intrinsic features of space-derived power, e.g., addressing marginal, high-value-added markets for electric power in space- and time-agile manners to conveniently provide power-upon-demand, and incrementally ''wedging'' into ever-larger markets with ever more cost-efficient generations and scales of technology. We suggest that no prudent strategic plan will rely upon large-scale, long-term public subsidies--fiscal, regulatory, etc.--with their attendant ''sovereign risks'' and interminable delays, and that plan-essential governmental support likely will be limited to early feasibility demonstrations, provision of threshold technologies and a rational, competition-neutral licensing environment. If salient realities are uniformly respected and accessible technologies are intelligently leveraged, electricity derived from space-sourced power-beams may come into significant civilian use during the latter part of the first quarter of this century, and may become widely used by the half-century point.

    Medical professionalism faces distinctive challenges in the 21st century. In this chapter, we review the history of professionalism, address specific challenges physicians face today, and provide an overview of efforts to address these issues, including behavioral and virtue ethics approaches. First, we discuss core features professions share and the development of codes of medical ethics that guide the practice of western medicine. Second, we address challenges related to the doctor-patient relationship, continuity of care, cultural competence, conflicts of interest, and the regulation of quality of care through maintenance of certification. We then explore three cultural trajectories that have deeply influenced medical practice: the technologic imperative, physicians' collective neglect of structural factors impacting medicine, and the rise of commercialism. Finally, we describe efforts to address these challenges, focusing on the Physician Charter developed by the American Board of Internal Medicine and widely endorsed by medical boards and societies internationally.

  14. A potential 21st century satellite communications application - Personal communications

    NASA Astrophysics Data System (ADS)

    Tsang, E. K.; Douville, R.

    1990-03-01

    It has been forecast that not only will the future needs for satellite communications grow, especially in the area of broadcasting and mobile services, but also that the requirements will be diversified. For voice and data traffic, satellite communications started with the requirements of the telephone companies. Over the past few years, with the availability of Ku-band and VSAT systems, private business networks have emerged. Heading into the 21st century, satellite communications will expand into the personal services domain. This paper describes a concept for a satellite-based personal radio system. To realize the personal communications system, the portable terminals have to be inexpensive and small, similar to the present portable or handheld cellular radio-phones in size. The system aspects, such as selection of frequency band, multiple access and payload configuration will be addressed. The advanced technology required for the portable personal satellite communications system will be discussed.

    Early in the 21st century, the Open Archival Information System Reference Model (OAIS-RM) swept across the international digital archive community, bringing with it a common language and functional framework for the long term preservation of environmental information. The OAIS-RM has had a significant impact within the National Oceanic and Atmospheric Administration (NOAA), where the archive-related roles and responsibilities of the various offices and entities within the agency were not clearly identified. This lack of clarity was especially acute with respect to interactions between the three NOAA National Data Centers - Oceanographic, Climatic, and Geophysical - and the Comprehensive Large Array-data Stewardship System (CLASS). Through 2008 and 2009, each of these offices individually, then together as a group, undertook an extensive mapping of their existing and planned capabilities to the functional entities of the OAIS-RM. The result of this process was a new clarity which puts the Data Centers forth as the NOAA Archives, with CLASS as the critical supporting information technology (IT) infrastructure. Under this new paradigm, the Data Centers lead all interactions with both data producers and consumers, reflecting their more discipline-focused involvement with and understanding of the designated communities they serve. The CLASS infrastructure focuses now on meeting the common IT requirements of the three Data Centers, reflecting its capabilities and expertise in designing and deploying rigorous IT systems. The new paradigm is allowing NOAA to move forward together in a more unified and cooperative manner, better aligned to meet the 21st century challenges of data stewardship.

    Through the ages each culture and civilization has expressed its values and world view in the form of monuments derived from its most advanced and valued technologies. From pyramids to cathedrals, skyscrapers and moon rockets, our technology has enabled us to leave our mark on the landscape and in the minds of our people. In the 21st century, the compelling technology will be that of the micro-world, enabling the fabrication of structures with features smaller than the wavelengths of light. Such structures will allow use to monitor and control electrical, chemical, and optical phenomena in ways never before imagined. As in the past we will continue to create monuments, but the technological monuments of the 21st century will likely be viewed through a microscope. This report provides a discussion of microtechnology in the 21st century.

    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

    1998-06-01

    The approaching millennium brings not only a muted but also a challenging vision for the future of gerontological nursing. This vision is muted by the rhetoric of the 90s dictating the elimination of costly programs with the potential to diminish quality. It is a vision of challenge to advocate for, protect, demand, and create a new framework that will guarantee high-quality health care for older patients. In an attempt to clarify that vision, this article outlines three areas of gerontological nursing: education, practice, and research. The future direction in these areas will dictate how collective thinking can support health care for older people in the next century and beyond. These components of nursing must be integrated to develop quality care needed by older patients.

    Ninety years ago, the first issue of the Postgraduate Medical Journal published a review of an article written by Mr Robert Lindsay-Rea, a consultant ophthalmic surgeon in the Western Ophthalmic Hospital and an oculist in the West End Hospital for Nervous Diseases, entitled "A preliminary report on the treatment of keratitis". Today, microbial keratitis remains an important cause of avoidable visual impairment in the world. The aetiology of microbial keratitis has changed greatly over the past century due to the discovery of antibiotics, improvement in sanitation and education, the rising trend of contact lens wear and increased air travel. Significant advances have also been made in our understanding and management of this important disorder. This article highlights some of these changes and discusses the current management and research.

    Compared to other bone tumors, bone osteogenic sarcoma (BOS) continues to confer a much grimmer prognosis as the survival benefit of traditional chemotherapy treatment regimens is still unsatisfactory. Chemotherapy was demonstrated to be effective in eradicating both primary tumor and pulmonary metastases in the last century, with effective agents used in various combination regimens having changed the survival rate from less than 10% to 75%. The most common primary bone cancer, BOS is conventionally a primary intramedullary high-grade malignant tumor characterized by malignant cells forming immature bone or osteoid. BOS is a disease with diverse morphological presentations. The treatment of all morphological variants seem to have been the same for over 30 years. The introduction of antiproliferative agents such as insulin growth factor-binding protein 3 hold promise of a potentially veritable therapeutic target. In this review, we highlight recent data on osteosarcoma to consolidate a platform able to connect bench and bedside. PMID:27630274

    The sophistication of science and teclinology is growing almost exponentially. Government and industry are relying more and more on science's advanced methods to assess reliability coupled with pcrformance, safety, surety, cost, schedule, etc. Unfortunately, policy, cost, schedule, and other constraints imposed by the real world inhibit the ability of researchers to calculate these metrics efficiently and accurately using traditional methods. Because of such constraints, reliability must undergo an evolutionary change. The first step in this evolution is to reinterpret the concepts and responsibilities of scientists responsible for reliability calculations to meet the new century's needs. The next step is to mount a multidisciplinary approach to the quantification of reliability and its associated metrics using both empirical methods and auxiliary data sources, such as expert knowledge, corporate memory, and mathematical modeling and simulation.

    Space Biology is poised to make significant contributions to science in the next century. A carefully crafted, but largely ground-based, program in the United States has evolved major questions that require answers through experiments in space. Science, scientists, and the new long-term spacecrafts designed by NASA will be available for the first time to mount a serious Space Biology effort. The scientific challenge is of such importance that success will provide countless benefits to biologically dependent areas such as medicine, food, and commerce in the decades ahead. The international community is rapidly expanding its role in this field. The United States should generate the resources that will allow progress in Space Biology to match the recognized progress made in aeronautics and the other space sciences.

    SciTech Connect

    Dearborn, D S

    2004-03-10

    The systematic requirements to divert an object on an earth-impacting course are developed relating the minimum velocity perturbation (both magnitude and direction) to the time available before impact. This, coupled with the accuracy to which orbits can be determined, restricts the time available for any mitigation technology to operate. Because nuclear energy densities are nearly a million times higher than those possible with chemical bonds, it is the most mass efficient means for storing delivering energy with today's technology. The question is how to most effectively apply that energy. This paper will examine the simple case of shattering the body, as well as a more controlled approach in which one or more small velocity increments divert a body. The optimal approach depends on the detailed circumstances, but in either case, already developed technology permits a successful diversion with a few years to decades of notice. The success of nuclear options on relatively short timescales permits consideration of other technologies that while not so well developed might be sufficiently improved to divert small (100 meter) bodies.

    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

    The Humane Society of the United States (HSUS) strongly endorses the vision for the future of toxicity testing proposed in the 2007 National Research Council report Toxicity Testing in the 21st Century. Although crafted primarily with the aim of better assessing the public health risks from chemical exposures, the vision would have a major impact on advancing both alternative testing methods and animal welfare. Consequently, The HSUS seeks to have the vision implemented expeditiously. The HSUS is pleased that the report has elicited considerable discussion and debate and garnered a certain level of approval and applaud current implementation efforts. However, these efforts do not fully capture the vision and strategy outlined by the NRC. The HSUS believes that the timely implementation of the NRC vision warrants a large-scale "Human Toxicology Project" akin to the Human Genome Project of the late 20th century. The HSUS spearheaded the formation of the Human Toxicology Project Consortium to help marshal the necessary will, funding, and research for this effort. Our sister organization, the Humane Society International, is embarking on a related effort with European partners. The HSUS cofounded a website, AltTox.org, devoted exclusively to the scientific and policy issues central to advancing nonanimal methods of toxicity testing. The NRC report has provided a unified framework by which to systematically incorporate the fruits of modern biology and technology into hazard identification and risk assessment, to the betterment not only of toxicity testing and public health, but also of animal protection.

    In preparation for Earth Science Week, The University of Texas at Austin, Striker Communications and Ursuline Academy of Dallas partnered on a GirlTalk event ("Energy, Climate and Water in the 21st Century") to create a two-day (Fri-Sat), community science symposium and open house on critical issues surrounding energy, water and climate. On Friday, over 800 high school girls and 100 teachers from Ursuline participated in hands-on activities (led by faculty, researchers and graduate students from UT Austin and professionals from the surrounding Dallas community), films and discussions, plenary sessions and an expert panel discussion. An opening talk by Dr. Hilary Olson on "Energy, Water and Climate in the 21st Century: Critical Issues for the Global Community" began the day. A series of hands-on activities, and science and technology films with discussion followed. Each girl had an individualized, modular schedule for the day, completing four of the over twenty modules offered. During lunch, Dr. Scott Tinker, Director of the Bureau of Economic Geology, presented a compelling talk on "Time, Technology and Transition", and afterwards girls attended another round of hands-on activities in the afternoon. The day ended with a panel discussion where girls could submit questions to the various participants from the day's activities. The exciting experience of a full day of GirlTalk led many high school girls to volunteer for the middle school event on the following morning (Sat.), when 150 middle school girls and their mentors (parents, teachers) attended a community-wide public event to learn about the energy, water and climate nexus. "Breakfast with a Pro" was hosted by the various professionals. Girls and their mentors enjoyed breakfast and discussion about topics and careers in the earth sciences and engineering with presenters, followed by an informal discussion with a panel of professionals.

    Digital pathology is rapidly developing, but early systems have been slow to gain traction outside of niche applications such as: Second-opinion telepathology, immunostain interpretation, and intraoperative telepathology. Pathologists have not yet developed a well-articulated plan for effectively utilizing digital imaging technology in their work. This paper outlines a proposal that is intended to begin meaningful progress toward achieving helpful computer-assisted pathology sign-out systems, such as pathologists’ computer-assisted diagnosis (pCAD). pCAD is presented as a hypothetical intelligent computer system that would integrate advanced image analysis and better utilization of existing digital pathology data from lab information systems. A detailed example of automated digital pathology is presented, as an automated breast cancer lymph node sign-out.

    This study examined bullying and cyberbullying prevalence among 367 adolescents 10 to 18 years of age who were attending schools and community organizations in suburban and urban neighborhoods in the Midwest United States. The correlational design investigated adolescents' daily use of technology that could be used to cyberbully peers, such as cell phones, computers, email, and the Internet. Results showed that 30% of participants had been bullied during school, and 17% had been cyberbullied, with online social networking sites the most common media employed (68%). The majority of participants owned or had access to computers (92%), email accounts (88%), social networking accounts (e.g., Facebook or MySpace) (82%), and cell phones (79%). Daily technology use included an average of two hours on a computer and a median of 71 text messages per day. Logistic regression analysis revealed no significant differences in bullying or cyberbullying prevalence based on location (urban or suburban) or demographic characteristics. Given the substantial presence of cyberbullying and the increase in technology use among adolescents in the 21st century, nurses need knowledge of the phenomenon to plan assessments in clinical practice. Early identification and assessment of cyberbullying victims and perpetrators, and development and implementation of effective interventions are needed to reduce this form of bullying among adolescents.

    2010-05-01

    Earthworm (Johnson et al., 1995) is a fully open-source earthquake data acquisition and processing package that is in widespread use through out the world. Earthworm includes basic seismic data acquistion for the majority of the dataloggers currently available and provides network transport mechanisms and common formats as output for data transferral. In addition, it comes with network seismology tools to compute network detections, perform automated arrival picking, and automated hypocentral and magnitude estimations. More importantly it is an open and free framework in the C-programming language that can be used to create new modules that process waveform and earthquake data in near real time. The number of Earthworm installations is growing annually as are the number of contributions to the system. Furthermore its growth into other areas of waveform data acquistion (namely Geomagnetic observatories and Infrasound arrays) show its adaptability to other waveform technologies and processing strategies. In this presentation we discuss the coming challenges to growing Earthworm and new developments in its use; namely the open source add-ons that have become interfaces to Earthworm's core. These add-ons include GlowWorm, MagWorm, Hydra, SWARM, Winston, EarlyBird, Iworm, and most importantly, AQMS (formerly known as CHEETAH). The AQMS, ANSS Quake Monitoring System, is the Earthworm system created in California which has now been installed in the majority of Regional Seismic Networks (RSNs) in the United States. AQMS allows additional real-time and post-processing of Earthworm generated data to be stored and manipulated in a database using numerous database oriented tools.

    In the era of global industrialisation, the exploration of natural resources has served as a source of experimentation for science and advanced technologies, giving rise to the manufacturing of products with high aggregate value in the world market, such as biosurfactants. Biosurfactants are amphiphilic microbial molecules with hydrophilic and hydrophobic moieties that partition at liquid/liquid, liquid/gas or liquid/solid interfaces. Such characteristics allow these biomolecules to play a key role in emulsification, foam formation, detergency and dispersal, which are desirable qualities in different industries. Biosurfactant production is considered one of the key technologies for development in the 21st century. Besides exerting a strong positive impact on the main global problems, biosurfactant production has considerable importance to the implantation of sustainable industrial processes, such as the use of renewable resources and "green" products. Biodegradability and low toxicity have led to the intensification of scientific studies on a wide range of industrial applications for biosurfactants in the field of bioremediation as well as the petroleum, food processing, health, chemical, agricultural and cosmetic industries. In this paper, we offer an extensive review regarding knowledge accumulated over the years and advances achieved in the incorporation of biomolecules in different industries.

    After the publication of the report titled Toxicity Testing in the 21st Century - A Vision and a Strategy, many initiatives started to foster a major paradigm shift for toxicity testing - from apical endpoints in animal-based tests to mechanistic endpoints through delineation of pathways of toxicity (PoT) in human cell based systems. The US EPA has funded an important project to develop new high throughput technologies based on human cell based in vitro technologies. These methods are currently being incorporated into the chemical risk assessment process. In the pharmaceutical industry, the efficacy and toxicity of new drugs are evaluated during preclinical investigations that include drug metabolism, pharmacokinetics, pharmacodynamics and safety toxicology studies. The results of these studies are analyzed and extrapolated to predict efficacy and potential adverse effects in humans. However, due to the high failure rate of drugs during the clinical phases, a new approach for a more predictive assessment of drugs both in terms of efficacy and adverse effects is getting urgent. The food industry faces the challenge of assessing novel foods and food ingredients for the general population, while using animal safety testing for extrapolation purposes is often of limited relevance. The question is whether the latest paradigm shift proposed by the Tox21c report for chemicals may provide a useful tool to improve the risk assessment approach also for drugs and food ingredients.

  10. The hateful patient revisited: Relevance for 21st century medicine.

    PubMed

    Strous, Rael D; Ulman, Anne-Marie; Kotler, Moshe

    2006-10-01

    While the practice of medicine has changed over the years, including technological advances, access to medical information, and the narrowing of socio-economic and educational gaps between the clinician and his/her patients, the importance of the doctor-patient relationship has not diminished over time. This can be a very rewarding interaction. However, many physicians experience a great deal of anger, inadequacy and frustration, and much of the actual practice of medicine may become a burden rather than a source of satisfaction. Physicians may encounter a subset of patients who engender strong negative feelings, despair and even downright malice. An understanding of the "hateful patient" can therefore be very informative to the physician. Several categories of such patients may be described, and sensitivity to the phenomenon will lead to improved physician well-being, less self-destructive patient behavior and a lower risk of litigation. Several factors may assist the 21st century physician in managing the "hateful patient" in an empathic manner and in making some sense of why the patient has resorted to negative response patterns. Ultimately, a failure to consider these issues will result in poorer medical care and, no less important, reduced satisfaction of both patients and doctors. The intention of this article is to revisit the concept and to place it in the context of contemporary medical practice.

  11. Undergraduate Neuroscience Education: Blueprints for the 21(st) Century.

    Wiertelak, Eric P; Ramirez, Julio J

    2008-01-01

    Paralleling the explosive growth of neuroscientific knowledge over the last two decades, numerous institutions from liberal arts colleges to research universities have either implemented or begun exploring the possibility of implementing undergraduate programs in neuroscience. In 1995, Faculty for Undergraduate Neuroscience (FUN) partnered with Project Kaleidoscope (PKAL) to offer a workshop exploring how undergraduate neuroscience education should proceed. Four blueprints were created to provide direction to the burgeoning interest in developing programs in undergraduate neuroscience education: 1) Neuroscience nested in psychology; 2) Neuroscience nested in biology; 3) Neuroscience as a minor; and 4) Neuroscience as a major. In 2005, FUN again partnered with PKAL to revisit the blueprints in order to align the blueprints with modern pedagogical philosophy and technology. The original four blueprints were modified and updated. One particularly exciting outgrowth of the 2005 workshop was the introduction of a fifth curricular blueprint that strongly emphasizes the integration of the humanities and social sciences into neuroscience: Neuroscience Studies. Because of the interdisciplinary nature of neuroscience, an education in neuroscience will prepare the next generation of students to think critically, synthetically, and creatively as they confront the problems facing humanity in the 21(st) century.

    The 1960's-era National Committee for Fluid Mechanics Films produced 39 famous 16mm films - dated but still in use - with 3 million dollars of NSF funding. Here we examine the nature of new fluid mechanics films, goals, media changes, and practicality. Examples are given of new narrated videos produced to illustrate chapters of a basic fluids text and provide a ``glimpse through the laboratory window.'' Both experiments and CFD are featured, though the facilities needed for the former are declining. The fundamentally-visual nature of the topic is emphasized with no repetition of text or equations. We believe this visual nature of fluid mechanics is the key to its role in renewed efforts to bolster US science education. This is one - not the only - paradigm for new fluid mechanics films. While inflation makes such film production perhaps 6 times more expensive than in the 1960's, there are offsetting economies based on consumer video technology and digital desktop production. Nonetheless, funding new educational fluid mechanics videos in the 21st century remains a daunting prospect.

    Prescott, Glenn; Komar, George (Technical Monitor)

    2001-01-01

    Future NASA Earth observing satellites will carry high-precision instruments capable of producing large amounts of scientific data. The strategy will be to network these instrument-laden satellites into a web-like array of sensors to facilitate the collection, processing, transmission, storage, and distribution of data and data products - the essential elements of what we refer to as "Information Technology." Many of these Information Technologies will enable the satellite and ground information systems to function effectively in real-time, providing scientists with the capability of customizing data collection activities on a satellite or group of satellites directly from the ground. In future systems, extremely large quantities of data collected by scientific instruments will require the fastest processors, the highest communication channel transfer rates, and the largest data storage capacity to insure that data flows smoothly from the satellite-based instrument to the ground-based archive. Autonomous systems will control all essential processes and play a key role in coordinating the data flow through space-based communication networks. In this paper, we will discuss those critical information technologies for Earth observing satellites that will support the next generation of space-based scientific measurements of planet Earth, and insure that data and data products provided by these systems will be accessible to scientists and the user community in general.

    Fittipaldi, J.J.; Sliwinski, B.J.

    1991-06-01

    Army environmental planning and compliance activities continue to grow in magnitude and complexity, straining the resources of installation environmental offices. New efficiencies must be found to meet the increasing demands of planning and compliance imperatives. This study examined how office automation/information technology (OA/IT) may boost productivity in U.S. Army Training and Doctrine Command (TRADOC) installation environmental offices between now and the year 2000. A survey of four TRADOC installation environmental offices revealed that the workload often exceeds the capacity of staff. Computer literacy among personnel varies widely, limiting the benefits available from OA/IT now in use. Since environmental personnel are primarily gatherers and processors of information, better implementation of OA/IT could substantially improve work quality and productivity. Advanced technologies expected to reach the consumer market during the 1990s will dramatically increase the potential productivity of environmental office personnel. Multitasking operating environments will allow simultaneous automation of communications, document processing, and engineering software. Increased processor power and parallel processing techniques will spur simplification of the user interface and greater software capabilities in general. The authors conclude that full implementation of this report's OA/IT recommendations could double TRADOC environmental office productivity by the year 2000.

  12. Global perspective on energy. [Projecting into 21st century

    Anderson, T.D.

    1980-04-11

    The technological world of today finds us with a population of over 4 billion with a doubling time of 30 to 40 years. Even with the rapid introduction of effective fertility control, the momentum of population - a phenomenon caused by a population age structure biased toward the young - will carry us to a population of 12 to 16 billion in the 21st century. With fixed land resources, the energy inputs to support the increased population will be several tims the present world energy consumption. How does this conclusion square with the notion that we are running out of energy. Are the billions of new people doomed to malnutrition and disease because we cannot provide the energy needed to support them. Answering in the negative, the author says: (1) proved reserves of conventional energy resources are substantial and the prospects of adding to these reserves are good; (2) unconventional resources of oil, gas, and uranium are many times larger than our present conventional reserves; and (3) nuclear fisson energy alone could support the world for several centuries. Even though the general energy picture is bright, the outlook for the less developed countries is not, he feels. To exploit the energy sources of the future requires large capital investments - something that only the developed countries can manage. One of the major contributions the developed countries can make to those that are less fortunate is to take the pressure off oil so as to stabilize the price and supply situation. In this regard, the US is in an excellent position to take the lead.

  13. [Prospect of chemotherapy in the 21st century].

    "Golden Era in Chemotherapy" has begun with the discovery of penicillin in the early 1940's and lasted for two decades during which many antibiotics were discovered. However, the once-believed bright prospect that every infectious disease could be eliminated on the earth by the discovery of antibiotics had to be canceled owing to the emerging of drug-resistant microbes. It was indeed a rat race. We are now at the point when we have to seek another way to combat infectious diseases: One possible way might be not to eradicate the microbes but to coexist with them so long as they do no harm to the human hosts. The first step of infection with pathogens to the host is the adherence of the microbes to the surface of host cells. Therefore, the method how to inhibit this adhesion of microbes to the host cells may provide a new tool to prevent the development of infectious diseases without elimination of microbes from the host. This is just an example of strategy by which humans and pathogens coexist at peace and should be taken into consideration for the development of new-type antibiotics or "anti-infective drugs" in the 21st century. The analysis of genome sequences has been accelerated recently for various pathogenic bacteria one by one. New targets in the pathogenic microbes for the development of new antibiotics can, therefore, be determined from the genetic point of view. The discovery of antibiotics has indeed been the history of collection of innumerable species and/or strains of bacteria from the soils to search for the biologically active anti-pathogenic agents. The current progress in the technology of molecular genetics, however, will certainly make it possible to search for active molecules by DNA technology; bacterial DNA but not whole microorganisms from the soil is to be transformed into the conventional bacteria and searched for active molecules with combat against pathogens.

  14. The 21st century decline in damaging European windstorms

    2016-08-01

    A decline in damaging European windstorms has led to a reduction in insured losses in the 21st century. This decline is explored by identifying a damaging windstorm characteristic and investigating how and why this characteristic has changed in recent years. This novel exploration is based on 6103 high-resolution model-generated historical footprints (1979-2014), representing the whole European domain. The footprint of a windstorm is defined as the maximum wind gust speed to occur at a set of spatial locations over the duration of the storm. The area of the footprint exceeding 20 ms-1 over land, A20, is shown to be a good predictor of windstorm damage. This damaging characteristic has decreased in the 21st century, due to a statistically significant decrease in the relative frequency of windstorms exceeding 20 ms-1 in north-western Europe, although an increase is observed in southern Europe. This is explained by a decrease in the quantiles of the footprint wind gust speed distribution above approximately 18 ms-1 at locations in this region. In addition, an increased variability in the number of windstorm events is observed in the 21st century. Much of the change in A20 is explained by the North Atlantic Oscillation (NAO). The correlation between winter total A20 and winter-averaged mean sea-level pressure resembles the NAO pattern, shifted eastwards over Europe, and a strong positive relationship (correlation of 0.715) exists between winter total A20 and winter-averaged NAO. The shifted correlation pattern, however, suggests that other modes of variability may also play a role in the variation in windstorm losses.

    2000-01-01

    Evidence on a broad range of time scales, from Proterozoic to the most recent periods, shows that the Earth's climate responds sensitively to global forcings. In the past few decades the Earth's surface has warmed rapidly, apparently in response to increasing anthropogenic greenhouse gases in the atmosphere. The conventional view is that the current global warming rate will continue or accelerate in the 21st century. I will describe an alternate scenario that would slow the rate of global warming and reduce the danger of dramatic climate change. But reliable prediction of future climate change requires improved knowledge of the carbon cycle and global observations that allow interpretation of ongoing climate change.

    A number of ecological problems (e.g., global warming, ozone depletion, deforestation, acid rain) have been identified, which threaten to reduce the quality of human life in the 21st century. These problems are human produced, resulting primarily from over-population and over-consumption. Alterations in people's awareness, attitudes, beliefs, and behaviors may stimulate changes in their political and economic systems, which in turn might foster the kind of lifestyle changes that could mitigate these ecological problems. Psychologists can play a role in helping individuals and systems advance toward the goal of becoming a sustainable society: one that satisfies its current needs without jeopardizing the prospects of future generations.

    The 21st Century Jobs Initiative has been launched in the context of new realities in Washington, D.C., rapid restructuring of the US economy and accelerating changes in the makeup of the East Tennessee economy driven by these and other external economic forces. Continuing downward pressure on Federal budgets for programs that support three key institutions in the region - DOE`s Oak Ridge complex, the Tennessee Valley Authority and research programs of the University of Tennessee - are especially threatening to the region. With a large part of its economy dependent on Federal spending, the area is at risk of troublesome impacts that could ripple out from the Oak Ridge and Knoxville home of these institutions throughout the entire 15-county {open_quotes}Resource Valley.{close_quotes} As these economic forces play out in the region`s economy, important questions arise. How will East Tennessee {open_quotes}earn its living{close_quotes} in the future if the Federal government role in the economy shrinks? What kind of new industries will be formed to replace those at risk due to Federal cutbacks and economic restructuring? Where will the jobs come from for the next generation of job seekers? These are among the questions driving the 21st Century Jobs Initiative, an action-oriented program designed and implemented by local leaders in response to the economic challenges facing East Tennessee. Fortunately, the region`s economy is strong today. Unemployment is at near record lows in most counties. Moreover, leaders are increasingly aware of the threats on the horizon and are already moving to action. And the impacts from the forces at work on the economy will probably come slowly, over the next decade or so. Based on economic research and input from local leaders knowledgeable about the economy, the 21st Century Jobs Initiative has set forth a strategic economic development plan for the region.

    Estimates on 21st century global mean surface temperature increase have generally been based on scenarios that do not include climate policies. Newly developed multi-gas mitigation scenarios now allow the assessment of possible impacts of climate policies on projected warming ranges. By combing emission pathway results from multiple energy-economic models, we show that these mitigation scenarios result in a range of 21st century temperature increase of 0.5 to 4.2°C over 1990 levels as compared to 1.3-7.3 °C for the no-policy cases. About half the range is due to differences in the assumed stringency of the global climate policy and half is due to uncertainty in our understanding of the climate system, specifically, the carbon cycle and climate sensitivity. A minimum warming of about 0.5-2.7°C (avg. 1.3oC) remains for even the most stringent stabilization scenarios analyzed here - highlighting the need for both emission mitigation and adaptation policies.

  1. Mobile DNA and evolution in the 21st century

    PubMed Central

    2010-01-01

    Scientific history has had a profound effect on the theories of evolution. At the beginning of the 21st century, molecular cell biology has revealed a dense structure of information-processing networks that use the genome as an interactive read-write (RW) memory system rather than an organism blueprint. Genome sequencing has documented the importance of mobile DNA activities and major genome restructuring events at key junctures in evolution: exon shuffling, changes in cis-regulatory sites, horizontal transfer, cell fusions and whole genome doublings (WGDs). The natural genetic engineering functions that mediate genome restructuring are activated by multiple stimuli, in particular by events similar to those found in the DNA record: microbial infection and interspecific hybridization leading to the formation of allotetraploids. These molecular genetic discoveries, plus a consideration of how mobile DNA rearrangements increase the efficiency of generating functional genomic novelties, make it possible to formulate a 21st century view of interactive evolutionary processes. This view integrates contemporary knowledge of the molecular basis of genetic change, major genome events in evolution, and stimuli that activate DNA restructuring with classical cytogenetic understanding about the role of hybridization in species diversification.

    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.

Tailor made chemotherapeutic agents, vast array of monoclonal antibodies, epigenetic modifiers, growth factors for red cells white cells and platelets, peptidomimetics as growth factors, newer thrombin inhibitors, safer plasma derived protein molecules, recombinant molecules, newer immunomodulators, enzyme replacement therapy and above all a plethora of targetted molecules targeting innumerable pathways involved in cell division, growth, proliferation and apoptosis has given immense number of clinically usable molecules in the hand of modern haematologists to treat diverse hitherto untreatable haematological disorders effectively. In addition many old molecules are finding newer uses in diverse fields, thalidomide as an antiangiogenic molecule is a prime example of this genre. Present overview has tried to capture this rapidly evolving area in a broad canvas without going into details of indications and contraindications of the use of various drugs. PMID:21629633

    Heat is the number-one weather related killer in the US and around the world. As a result of rising temperatures and steady or slightly rising levels of specific humidity, heat stress is projected to become increasingly severe. Here we show that heat stress as measured by two common indices -- the heat index and the wet-bulb temperature -- is projected to rapidly and dramatically increase, and that by mid-century crippling summertime conditions are possible across some of the most densely populated regions of the planet. Many of these regions are places where cooling infrastructure is scarce, adaptive capacity is low, and populations are rapidly rising. We find that by the end of the 21st century, the habitability of some regions of the planet may be questionable due to heat stress alone, and in many other regions severe impacts to human health, infrastructure, agriculture, and economic performance will create significant societal stress and necessitate rapid adaptation.

NASA's vision for 21st Century Aircraft is to develop propulsion systems that are intelligent, virtually inaudible (outside the airport boundaries), and have near zero harmful emissions (CO2 and Knox). This vision includes intelligent engines that will be capable of adapting to changing internal and external conditions to optimally accomplish the mission with minimal human intervention. The distributed vectored propulsion will replace two to four wing mounted or fuselage mounted engines by a large number of small, mini, or micro engines, and the electric drive propulsion based on fuel cell power will generate electric power, which in turn will drive propulsors to produce the desired thrust. Such a system will completely eliminate the harmful emissions. This paper reviews future propulsion and power concepts that are currently under development at NASA Glenn Research Center.

    This paper identifies the contribution of health and clinical informatics in the support of healthcare in the 21st century. Although little is known about the health and clinical informatics workforce, there is widespread recognition that the health informatics workforce will require significant expansion to support national eHealth work agendas. Workforce issues including discipline definition and self-identification, formal professionalisation, weaknesses in training and education, multidisciplinarity and interprofessional tensions, career structure, managerial support, and financial allocation play a critical role in facilitating or hindering the development of a workforce that is capable of realising the benefits to be gained from eHealth in general and clinical informatics in particular. As well as the national coordination of higher level policies, local support of training and allocation of sufficient position hours in appropriately defined roles by executive and clinical managers is essential to develop the health and clinical informatics workforce and achieve the anticipated results from evolving eHealth initiatives.

The demands of the changing health care environment require that managers and staff change the context in which patient care delivery is accomplished. Managers must be willing to unleash the power of the human capital of staff nurses. Staff nurses must be willing to take a seat at the table and share the leadership role with their manager. Both must engage in building an environment that facilitates continued learning, establishes effective relationships with other health care team members and patients, creates an environment that attracts and retains professional nursing staff, expects professional development from one another, and realizes that collective accountability can be achieved through sharing the leadership.

VLA and Radio Galaxy VLA Antennas Getting Modern Electronics To Meet New Scientific Challenges CREDIT: NRAO/AUI/NSF Click on image for more information, higher-resolution files "We're taking a facility that has made landmark discoveries in astronomy for three decades and making it 10 times more powerful, at a cost that's a fraction of its total value, by replacing outdated technology with modern equipment," said Mark McKinnon, project manager for the Expanded VLA (EVLA). Rick Perley, EVLA project scientist, added: "When completed in 2012, the EVLA will be 10 times more sensitive, cover more frequencies, and provide far greater analysis capabilities than the current VLA. In addition, it will be much simpler to use, making its power available to a wider range of scientists." The EVLA will give scientists new power and flexibility to meet the numerous challenges of 21st-Century astrophysics. The increased sensitivity will reveal the earliest epochs of galaxy formation, back to within a billion years of the Big Bang, or 93 percent of the look-back time to the beginning of the Universe. It will have the resolution to peer deep into the dustiest star-forming clouds, imaging protoplanetary disks around young stars on scales approaching that of the formation of terrestrial planets. The EVLA will provide unique capabilities to study magnetic fields in the Universe, to image regions near massive black holes, and to systematically track changes in transient objects

    accelerate the development of new tools for the future. Simple improvements in tuberculosis control, such as expanding the use of under-utilized technologies, can have enormous impact. Fixed-dose combinations have existed for over 25 years, and could help ensure that more patients complete treatment; yet globally, only 15 percent of patients are using them. We also need new drugs, vaccines and diagnostics, as well as innovations in tuberculosis control and case management. Better diagnostics are already available, and new drugs and vaccines are coming. But more commitment and resources are needed. Better prevention and control of tuberculosis is the surest way to stop drug resistance. To ensure that drug resistance does not pose a wider threat, we need to employ a number of equally important approaches. These include improved basic tuberculosis control, increased use of underutilized technologies such as fixed-dose combinations, and new technologies and health systems innovations. At the same time, we should expand access to M/XDR-TB treatment and diagnostics for those who already have drug resistant tuberculosis. Some of the most innovative solutions can come from the private sector and through partnerships. An untapped market of two billion people carries the tuberculosis bacterium. Since tuberculosis requires a comprehensive approach, companies should also explore opportunities to work together and pool complementary technologies to ensure new tools are used most effectively. Japan is poised to play a leading role in the discovery, development and delivery of tuberculosis solutions in the 21st century.

    Space missions of the 21st Century will be characterized by constellations of distributed spacecraft, miniaturized sensors and satellites, increased levels of automation, intelligent onboard processing, and mission autonomy. Programmatically, these missions will be noted for dramatically decreased budgets and mission development lifecycles. Current progress towards flexible, scaleable, low-cost, reusable mission control systems must accelerate given the current mission deployment schedule, and new technology will need to be infused to achieve desired levels of autonomy and processing capability. This paper will discuss current and future missions being managed at NASA's Goddard Space Flight Center in Greenbelt, MD. It will describe the current state of mission control systems and the problems they need to overcome to support the missions of the 21st Century.

  5. Persisting cold extremes under 21st-century warming scenarios

    SciTech Connect

    2011-01-01

    Analyses of climate model simulations and observations reveal that extreme cold events are likely to persist across each land-continent even under 21st-century warming scenarios. The grid-based intensity, duration and frequency of cold extreme events are calculated annually through three indices: the coldest annual consecutive three-day average of daily maximum temperature, the annual maximum of consecutive frost days, and the total number of frost days. Nine global climate models forced with a moderate greenhouse-gas emissions scenario compares the indices over 2091 2100 versus 1991 2000. The credibility of model-simulated cold extremes is evaluated through both bias scores relative to reanalysis data in the past and multi-model agreement in the future. The number of times the value of each annual index in 2091 2100 exceeds the decadal average of the corresponding index in 1991 2000 is counted. The results indicate that intensity and duration of grid-based cold extremes, when viewed as a global total, will often be as severe as current typical conditions in many regions, but the corresponding frequency does not show this persistence. While the models agree on the projected persistence of cold extremes in terms of global counts, regionally, inter-model variability and disparity in model performance tends to dominate. Our findings suggest that, despite a general warming trend, regional preparedness for extreme cold events cannot be compromised even towards the end of the century.

    Agriculturalists in the 21st century will be farming crops in different climates than today. Atmospheric CO{sub 2} will likely exceed 700 {micro}l l{sup {minus}1} by the latter half of the next century, and the mean global temperature has been predicted to be 1.5 to 5.9 C higher than today. Further, the incidence of extreme weather events within a growing season has been predicated to increase. Extreme-weather events often limit crop yields even in today`s environment; e.g., a late spring may severely limit a citrus or winter wheat crop. Agricultural productivity is extremely sensitive to changes projected in the environment, particularly where crops are produced in marginal areas. The authors conducted several studies in which plants were grown in controlled environments with natural radiation levels. Carbon dioxide, water, temperature, and nutrients were each varied independently while the other factors were maintained at nearly optimum conditions. Photosynthesis, transpiration, growth and rate of development were measured. At nearly optimum temperature (26 to 28 C), doubling today`s atmospheric CO{sub 2} concentration results in about 50% increase in biomass production with only trivial changes in the ratio of vegetative to fruit or grain production. However, fruit or grain production is drastically reduced at above-optimum temperatures. The authors examined long-term climatology data from four areas in the US Cotton Belt and a maritime climate, Maros, Indonesia.

    Simulations from eleven coupled chemistry-climate models (CCMs) employing nearly identical forcings have been used to project the evolution of stratospheric ozone throughout the 21st century. The model-to-model agreement in projected temperature trends is good, and all CCMs predict continued, global mean cooling of the stratosphere over the next 5 decades, increasing from around 0.25 K/decade at 50 hPa to around 1 K/decade at 1 hPa under the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) A1B scenario. In general, the simulated ozone evolution is mainly determined by decreases in halogen concentrations and continued cooling of the global stratosphere due to increases in greenhouse gases (GHGs). Column ozone is projected to increase as stratospheric halogen concentrations return to 1980s levels. Because of ozone increases in the middle and upper stratosphere due to GHG-induced cooling, total ozone averaged over midlatitudes, outside the polar regions, and globally, is projected to increase to 1980 values between 2035 and 2050 and before lower-stratospheric halogen amounts decrease to 1980 values. In the polar regions the CCMs simulate small temperature trends in the first and second half of the 21st century in midwinter. Differences in stratospheric inorganic chlorine (Cly) among the CCMs are key to diagnosing the intermodel differences in simulated ozone recovery, in particular in the Antarctic. It is found that there are substantial quantitative differences in the simulated Cly, with the October mean Antarctic Cly peak value varying from less than 2 ppb to over 3.5 ppb in the CCMs, and the date at which the Cly returns to 1980 values varying from before 2030 to after 2050. There is a similar variation in the timing of recovery of Antarctic springtime column ozone back to 1980 values. As most models underestimate peak Cly near 2000, ozone recovery in the Antarctic could occur even later, between 2060 and 2070. In the

    In the second half of the 20th century it became obvious that a relentless increase in diabetes type 2 (DM) affecting the economically affluent countries, is gradually afflicting also the developing world. This review juxtaposes the threat that the DM epidemic represents to mankind, with the astonishing recent discoveries on the role of obesity and of the body fat in this metabolic disorder. Presently, the highest prevalence of DM is in Saudi Arabia, a country deep in riches generated by its oil wells. DM is very high, in over 10% of adults in the USA, Switzerland and Austria. Prevalence is low in Norway, China and in Iceland. Predictions of epidemiologists for the first third of the 21st century claim up to 2.5 times increase in DM in the Middle East, Sub-Saharan Africa, India, rest of Asia and in the Latin America. In China the number of patients with DM will double but in the economically advanced countries that experienced rise in DM in the 20th century, the increase will be only about 50%. Remarkably, a lowest increase in DM is expected in the countries that formerly belonged to the Soviet political space. Increasing urbanization, aging populations, obesity, and falling levels of physical activity are all contributing to the rise of DM worldwide. The main cause of DM pandemic is growing prevalence of obesity, in Europe and in the Latin America. In the North America obesity is considered to be responsible for 90% of DM in females. Male obesity is associated with DM slightly less, at 70-80% in the European Union and in the US. The precise mechanism by which obesity leads to insulin resistance and to DM is not completely described but it may be related to several biochemical factors, such as abnormalities in free fatty acids, adipokines, leptin and other substances (Tab. 1, Fig. 4, Ref. 24).

    Although tumors on the surface of the skin are considered to be easily recognizable, neglected advanced skin neoplasms are encountered even in the 21st century. There can be numerous causes of the delay in the diagnosis: fear of the diagnosis and the treatment, becoming accustomed to a slowly growing tumor, old age, a low social milieu, and an inadequate hygienic culture are among the factors leading some people not to seek medical advice. The treatment of such advanced neoplasms is usually challenging. The therapy of neglected cases demands an individual multidisciplinary approach and teamwork. Basal cell carcinoma (BCC), the most common cutaneous tumor, usually develops in the elderly, grows slowly, and has an extremely low metastatic potential; these factors are suggesting that BCCs might well be the “ideal candidates” for neglected tumors. Five neglected advanced cases of BCC were diagnosed in our dermatological institute between 2000 and 2009. The clinical characteristics and treatment modalities of these neoplasms are discussed, together with the possible causes of the neglect. PMID:21151693

    The Health and Environmental Sciences Institute (HESI)-coordinated Risk Assessment in the 21st Century (RISK21) project was initiated to develop a scientific, transparent, and efficient approach to the evolving world of human health risk assessment, and involved over 120 participants from 12 countries, 15 government institutions, 20 universities, 2 non-governmental organizations, and 12 corporations. This paper provides a brief overview of the tiered RISK21 framework called the roadmap and risk visualization matrix, and articulates the core principles derived by RISK21 participants that guided its development. Subsequent papers describe the roadmap and matrix in greater detail. RISK21 principles include focusing on problem formulation, utilizing existing information, starting with exposure assessment (rather than toxicity), and using a tiered process for data development. Bringing estimates of exposure and toxicity together on a two-dimensional matrix provides a clear rendition of human safety and risk. The value of the roadmap is its capacity to chronicle the stepwise acquisition of scientific information and display it in a clear and concise fashion. Furthermore, the tiered approach and transparent display of information will contribute to greater efficiencies by calling for data only as needed (enough precision to make a decision), thus conserving animals and other resources.

  12. Bionic autonomic neuromodulation revolutionizes cardiology in the 21st century.

    PubMed

    Sunagawa, Kenji

    2009-01-01

    In this invited session, we would like to address the impact of bionic neuromodulation on cardiovascular diseases. It has been well established that cardiovascular dysregulation plays major roles in the pathogenesis of cardiovascular diseases. This is the reason why most drugs currently used in cardiology have significant pharmacological effects on the cardiovascular regulatory system. Since the ultimate center for cardiovascular regulation is the brainstem, it is conceivable that autonomic neuromodulation would have significant impacts on cardiovascular diseases. On the basis of this framework, we first developed a bionic, neurally regulated artificial pacemaker. We then substituted the brainstem by CPU and developed a bionic artificial baroreflex system. We further developed a bionic brain that achieved better regulatory conditions than the native brainstem in order to improve survival in animal model with heart failure. We recently developed a bionic neuromodulation system to reduce infarction size following acute myocardial infarction. We believe that the bionic neuromodulation will inspire even more intricate applications in cardiology in the 21(st) century.

    This paper identifies the contribution of health and clinical informatics in the support of healthcare in the 21st century. Although little is known about the health and clinical informatics workforce, there is widespread recognition that the health informatics workforce will require significant expansion to support national eHealth work agendas. Workforce issues including discipline definition and self-identification, formal professionalisation, weaknesses in training and education, multidisciplinarity and interprofessional tensions, career structure, managerial support, and financial allocation play a critical role in facilitating or hindering the development of a workforce that is capable of realising the benefits to be gained from eHealth in general and clinical informatics in particular. As well as the national coordination of higher level policies, local support of training and allocation of sufficient position hours in appropriately defined roles by executive and clinical managers is essential to develop the health and clinical informatics workforce and achieve the anticipated results from evolving eHealth initiatives.

    The aim of this article is to bring forward and realise the size of cardiovascular diseases and the burden of its numbers that concern practising doctors in Lower Silesia, in Poland, Europe and the world. Every fourth patient knocking at the GP's door comes with a problem with the circulatory system. These diseases are the reason for every second in hospitalization or referral to a specialist. The most common diagnosis is not the common cold but arterial hypertension. Three of the most common diseases in patients over 65 years old are: hypertension, ischaemic heart disease, and atherosclerosis of the brain arteries. Poland belongs to the group of developed countries with an emerging economy, where degenerative diseases dominate, and cardiovascular diseases account for the biggest problems within the Health System. Nearly half of male deaths (46%) and over half of female deaths (56%) are the consequence of cardiovascular diseases. 80% of people around the world live in developing economies, where cardiovascular diseases cause 23% of all deaths. Every fifth person lives in a developed country and has a 50% chance of dying because of cardiovascular diseases. Will these diseases become "the number one killer" of the 21st century? 27% lost healthy life years are due to arterial hypertension, ischeamic heart disease, and congestive heart failure so their epidemiology is being regarded in this article.

  15. Stratospheric ozone in the 21st Century: The chlorofluorocarbon problem

    SciTech Connect

    Rowland, F.S. )

    1991-04-01

    Ozone (O{sub 3}) exists in a dynamic equilibrium in the stratosphere, balanced between formation by solar ultraviolet photolysis ({lambda} < 242 nm) of molecular O{sub 2} (O + O{sub 2} {yields} O{sub 3}) and destruction by various chemical processes including several chain reaction sequences triggered by HO{sub x}, NO{sub x}, and ClO{sub x} radicals. The ozone dissipates over Antarctica by November through northward mixing, only to begin reappearing in late August of the following year. Substantial ozone losses have also appeared, although not as spectacularly as over Antarctica, in the Northern Hemisphere's temperate and polar regions. The primary cause for the Antarctic ozone loss, and the probable cause for the northern losses, is the increasing concentration in the stratosphere of anthropogenic chlorine, especially chlorine released by solar UV photolysis from chlorofluorocarbon (CFC) compounds such as CCl{sub 2}F{sub 2} (CFC-12), CCl{sub 3}F (CFC-11) and CCl{sub 2}FCClF{sub 2} (CFC-113). Because these molecules have average atmospheric lifetimes of many decades, excess anthropogenic chlorine will persist in the stratosphere for comparable time periods, and the Antarctic ozone hole will be an important atmospheric phenomenon throughout the 21st century.

    2004-05-01

    Air transportation in the new millennium will require revolutionary solutions to meet public demand for improving safety, reliability, environmental compatibility, and affordability. NASA's vision for 21st century aircraft is to develop propulsion systems that are intelligent, highly efficient, virtually inaudible (outside airport boundaries), and have near zero harmful emissions (CO 2 and NO x). This vision includes intelligent engines capable of adapting to changing internal and external conditions to optimally accomplish missions with either minimal or no human intervention. Distributed vectored propulsion will replace current two to four wing mounted and fuselage mounted engine configurations with a large number of small, mini, or micro engines. Other innovative concepts, such as the pulse detonation engine (PDE), which potentially can replace conventional gas turbine engines, also are reviewed. It is envisioned that a hydrogen economy will drive the propulsion system revolution towards the ultimate goal of silent aircrafts with zero harmful emissions. Finally, it is envisioned that electric drive propulsion based on fuel cell power will generate electric power, which in turn will drive propulsors to produce the desired thrust. This paper reviews future propulsion and power concepts that are under development at the National Aeronautics and Space Administration's (NASA) John H. Glenn Research Center at Lewis Field, Cleveland, Ohio, USA.

The purpose of this methodology is to optimize the use of prior information and testing resources (animals, time, facilities, and personnel) to efficiently and transparently reach a risk and/or safety determination. Based on the particular problem, exposure and toxicity data should have sufficient precision to make such a decision. Estimates of exposure and toxicity, bounded by variability and/or uncertainty, are plotted on the X- and Y-axes of the RISK21 matrix, respectively. The resulting intersection is a highly visual representation of estimated risk. Decisions can then be made to increase precision in the exposure or toxicity estimates or declare that the available information is sufficient. RISK21 represents a step forward in the goal to introduce new methodologies into 21st century risk assessment. Indeed, because of its transparent and visual process, RISK21 has the potential to widen the scope of risk communication beyond those with technical expertise.

  18. Langley Ground Facilities and Testing in the 21st Century

    2010-01-01

    A strategic approach for retaining and more efficiently operating the essential Langley Ground Testing Facilities in the 21st Century is presented. This effort takes advantage of the previously completed and ongoing studies at the Agency and National levels. This integrated approach takes into consideration the overall decline in test business base within the nation and reduced utilization in each of the Langley facilities with capabilities to test in the subsonic, transonic, supersonic, and hypersonic speed regimes. The strategy accounts for capability needs to meet the Agency programmatic requirements and strategic goals and to execute test activities in the most efficient and flexible facility operating structure. The structure currently being implemented at Langley offers agility to right-size our capability and capacity from a national perspective, to accommodate the dynamic nature of the testing needs, and will address the influence of existing and emerging analytical tools for design. The paradigm for testing in the retained facilities is to efficiently and reliably provide more accurate and high-quality test results at an affordable cost to support design information needs for flight regimes where the computational capability is not adequate and to verify and validate the existing and emerging computational tools. Each of the above goals are planned to be achieved, keeping in mind the increasing small industry customer base engaged in developing unpiloted aerial vehicles and commercial space transportation systems.

    The scientific study of human hookworm infection began at the dawn of the twentieth century. In recent years, there have been dramatic improvements in our understanding of many aspects of this globally widespread parasite. This chapter reviews recent advances in our understanding in the biology, immunology, epidemiology, public health significance and control of hookworm, and to look forward to the study of this important parasite in the 21st century. Advances in molecular biology has lead to the identification of a variety of new molecules from hookworms, which have importance either in the molecular pathogenesis of hookworm infection or in the host-parasite relationship; some are also promising vaccine targets. At present, relatively little is known about the immune responses to hookworm infection, although it has recently been speculated that hookworm and other helminths may modulate specific immune responses to other pathogens and vaccines. Our epidemiological understanding of hookworm has improved through the development of mathematical models of transmission dynamics, which coupled with decades of field research across multiple epidemiological settings, have shown that certain population characteristics can now be recognised as common to the epidemiology, population biology and control of hookworm and other helminth species. Recent recognition of the subtle, but significant, impact of hookworm on health and education, together with the simplicity, safety, low cost and efficacy of chemotherapy has spurred international efforts to control the morbidity due to infection. Large-scale treatment programmes are currently underway, ideally supported by health education and integrated with the provision of improved water and sanitation. There are also on-going efforts to develop novel anthelmintic drugs and anti-hookworm vaccines.

  1. Maunder's Butterfly Diagram in the 21st Century

    2005-01-01

    E. Walter Maunder created his first "Butterfly Diagram" showing the equatorward drift of the sunspot latitudes over the course of each of two solar cycles in 1903. This diagram was constructed from data obtained through the Royal Greenwich Observatory (RGO) starting in 1874. The RGO continued to acquire data up until 1976. Fortunately, the US Air Force (USAF) and the US National Oceanic and Atmospheric Administration (NOAA) have continued to acquire similar data since that time. This combined RGO/USAF/NOAA dataset on sunspot group positions and areas now extends virtually unbroken from the 19th century to the 21st century. The data represented in the Butterfly Diagram contain a wealth of information about solar activity and the solar cycle. Solar activity (as represented by the sunspots) appears at mid-latitudes at the start of each cycle. The bands of activity spread in each hemisphere and then drift toward the equator as the cycle progresses. Although the equator itself tends to be avoided, the spread of activity reaches the equator at about the time of cycle maximum. The cycles overlap at minimum with old cycle spots appearing near the equator while new cycle spots emerge in the mid-latitudes. Large amplitude cycles tend to have activity starting at higher latitudes with the activity spreading to higher latitudes as well. Large amplitude cycles also tend to be preceded by earlier cycles with faster drift rates. These drift rates may be tied to the Sun s meridional circulation - a component in many dynamo theories for the origin of the sunspot cycle. The Butterfly Diagram must be reproduced in any successful dynamo model for the Sun.

    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 21st 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.

    Ghil, M.

    The scientific problems posed by the Earth's fluid envelope, and its atmosphere, oceans, and the land surface that interacts with them are central to major socio-economic and political concerns as we move into the 21st century. It is natural, therefore, that a certain impatience should prevail in attempting to solve these problems. The point of this review paper is that one should proceed with all diligence, but not excessive haste: "festina lente," as the Romans said two thousand years ago, i.e. "hurry in a measured way." The paper traces the necessary progress through the solutions to the ten problems: 1. What is the coarse-grained structure of low-frequency atmospheric variability, and what is the connection between its episodic and oscillatory description? 2. What can we predict beyond one week, for how long, and by what methods? 3. What are the respective roles of intrinsic ocean variability, coupled ocean-atmosphere modes, and atmospheric forcing in seasonal-to-interannual variability? 4. What are the implications of the answer to the previous problem for climate prediction on this time scale? 5. How does the oceans' thermohaline circulation change on interdecadal and longer time scales, and what is the role of the atmosphere and sea ice in such changes? 6. What is the role of chemical cycles and biological changes in affecting climate on slow time scales, and how are they affected, in turn, by climate variations? 7. Does the answer to the question above give us some trigger points for climate control? 8. What can we learn about these problems from the atmospheres and oceans of other planets and their satellites? 9. Given the answer to the questions so far, what is the role of humans in modifying the climate? 10. Can we achieve enlightened climate control of our planet by the end of the century? A unified framework is proposed to deal with these problems in succession, from the shortest to the longest timescale, i.e. from weeks to centuries and millennia. The

    Climate models unanimously project a decline in the extent and thickness of Arctic sea ice as the climate warms, but at differing rates. Projecting the timing of an ice-free Arctic is a topic that has received considerable scientific and public attention. An ice-free Arctic opens up the potential for shorter global trade routes through the Arctic Ocean and there has already been a sharp increase in the number of transits along Russia's Northern Sea Route with escorts from nuclear powered icebreakers.Here we present results on the future of trans-Arctic shipping using bias corrected sea ice thickness projections, utilising the CMIP5 multi-model ensemble and considering multiple emission scenarios. We find that for 'Open Water' vessels (normal ocean going vessels that possess no specific ice strengthening), unaided trans-Arctic shipping is likely to become feasible in the next couple of decades. We find that the North West Passage will open approximately a decade later than the Northern Sea Route. Initially however, both routes exhibit marked inter-annual variability in accessibility which we quantify. The hypothesised trans-polar sea route through international waters via the North Pole will start to become navigable by 2050. Towards the latter period of the 21st century, normal ocean going vessels will be able to transit their choice of any of these routes for at least six months of any given year under the RCP 8.5 high future emissions scenario and four months for the lower RCP 4.5 emissions scenario. These findings suggest that further increases in global temperature could transform the Arctic into a global transport hub.

    2001-02-01

    Launching payloads into space continues to be a weekly occurrence around the world. Although it is becoming commonplace, it has not become a low-cost or low-risk, quick and simple process. Out of these conditions, concepts have been developed and efforts are underway to create a generic set of processes and tools that will advance payload processing into the 21st Century by making it more efficient and less complicated. These new approaches are developing more cost effective, shorter cycle time processes, and require fewer resources than in the past. The KSC Center of Excellence for Payload Processing, built on the last 40 years of experience in processing all types of payloads (Shuttle, Expendable, Space Station, etc.), has been addressing these areas. Development is complete and operations are underway on the high fidelity checkout system used to perform final verification of flight interfaces between the International Space Station (ISS) and its science experiments. This system is typical of what has been used in the past for verifying interfaces which include: high, medium, and low rate data communications; video, command and data handling; power; and fluids/gases. The system also contains an ISS Program equivalent ground station, which will receive and process payload telemetry and distribute that telemetry to the appropriate customers. The recently developed concepts and projects underway address the lifecycle of payload processing, integrating agency and customer needs and requirements, and support geographically distributed processing. These concepts have driven out areas of synergy and leverage which enable large improvements to be proposed for payloads headed for Space Station or flying on Shuttle. .

    2001-01-01

    As we enter the 21st century, military medicine struggles with critical issues. One of the most important issues is how to train medical personnel in peace for the realities of war. In April, 1998, The General Accounting Office (GAO) reported, "Military medical personnel have almost no chance during peacetime to practice battlefield trauma care skills. As a result, physicians both within and outside the Department of Defense (DOD) believe that military medical personnel are not prepared to provide trauma care to the severely injured soldiers in wartime. With some of today's training methods disappearing, the challenge of providing both initial; and sustainment training for almost 100,000 military medical personnel is becoming insurmountable. The "training gap" is huge and impediments to training are mounting. For example, restrictions on animal use are increasing and the cost of conducting live mass casualty exercises is prohibitive. Many medical simulation visionaries believe that four categories of medical simulation are emerging to address these challenges. These categories include PC-based multimedia, digital mannequins, virtual workbenches, and total immersion virtual reality (TIVR). The use of simulation training can provide a risk = free realistic learning environment for the spectrum of medical skills training, from buddy-aid to trauma surgery procedures. This will, in turn, enhance limited hands on training opportunities and revolutionize the way we train in peace to deliver medicine in war. High-fidelity modeling will permit manufacturers to prototype new devices before manufacture. Also, engineers will be able to test a device for themselves in a variety of simulated anatomical representations, permitting them to "practice medicine".

    The name "21 st Century Laboratory" is an emerging concept of how NASA (and the world) will conduct research in the very near future. Our approach is to carefully plan for significant technological changes in products, organization, and society. The NASA mission can be the beneficiary of these changes, provided the Agency prepares for the role of 21st Century laboratories in research and technology development and its deployment in this new age. It has been clear for some time now that the technology revolutions, technology "mega-trends" that we are in the midst of now, all have a common element centered around advanced computational modeling of small scale physics. Whether it is nano technology, bio technology or advanced computational technology, all of these megatrends are converging on science at the very small scale where it is profoundly important to consider the quantum effects at play with physics at that scale. Whether it is the bio-technology creation of "nanites" designed to mimic our immune system or the creation of nanoscale infotechnology devices, allowing an order of magnitude increase in computational capability, all involve quantum physics that serves as the heart of these revolutionary changes.

    Li, Pengfei; Irvine, Brian; Holden, Joseph

    2015-04-01

    Many peatlands across the world are suffering from degradation and erosion exacerbated by human influences. Blanket peat erosion has adverse impacts on terrestrial and aquatic habitats, reservoir capacity and water quality, and also leads to accelerated carbon release. Bioclimatic modelling suggests that some areas, which are currently suitable for active peat growth, may be no longer under a climate supporting the accumulation of peat by the end of the century. Peat erosion in these marginal regions is thus more likely. A recently developed blanket peat erosion model, PESERA-PEAT, was established through significantly modifying the grid version of the Pan-European Soil Erosion Assessment model (PESERA-GRID) to explicitly include the freeze-thaw and desiccation processes, which appear to be the crucial drivers of peat erosion, and typical land management practices in blanket peatlands such as artificial drainage, grazing and managed burning. Freeze-thaw and desiccation are estimated based on climate (i.e. temperature) and soil moisture conditions. Land management practices interact with hydrology, erosion and vegetation growth via their influence on vegetation cover, biomass and soil moisture condition. The model has been demonstrated to be robust for blanket peat erosion modelling with riverine sediment flux data in the UK. In this paper, the PESERA-PEAT model is applied to investigate the impact of environmental change on the blanket peat erosion at a global scale. Climatic scenarios to the end of 21st Century were derived, as part of the QUEST-GSI initiative, from the outputs of seven global climate models: CGCM3 and CCCMA (Canada); CSIRO Mark III (Australia); IPSL (France); ECHAM5 (Germany); CCSM (US National Centre for Atmospheric Research (NCAR)); HadCM3 and HadGEM1 (UK). Land management practice such as artificial drainage is considered to examine if it is possible to buffer the impact of climate change on erosion through managing blanket peatlands in

    Despite the technological and organisational advances of 21st century health-care systems, care scandals and burgeoning complaints from patients have raised concerns about patient neglect in hospitals. This article reviews the concept of patient neglect and the role of community health psychology in understanding its occurrence. Patient neglect has previously been conceptualised as a problem associated with hospital staff attitudes and behaviours, with regulation and training cited as solutions. Yet, a community health psychology perspective shows that the wider symbolic, material and relational aspects of care are crucial for understanding why patient neglect occurs and for outlining new solutions to augment existing interventions.

    Cholera, an acute water-borne diarrheal illness, has reemerged as a significant health threat across much of the developing world. Despite major advances in the ecological and the microbiological understanding of the causative agent, V. cholerae, the role of the underlying climatic and environmental processes in propagating transmission is not adequately understood. Recent findings suggest a more prominent role of hydroclimatic extremes - droughts and floods - on the unique dual cholera peaks in the Bengal Delta region of South Asia, the native homeland of cholera. Increasing water scarcity and abundance, and coastal sea-level rise, influenced by changing climate patterns and large-scale climatic phenomena, is likely to adversely impact cholera transmission in South Asia. We focus on understanding how associated changes in macro-scale conditions in this region will impact micro-scale processes related to cholera in coming decades. We use the PRECIS Regional Climate Model over the Ganges-Brahmaputra-Meghna (GBM) basin region to simulate detailed high resolution projections of climate patterns for the 21st century. Precipitation outputs are analyzed for the 1980-2040 period to identify the trends and changes in hydroclimatic extremes and potential impacts on cholera dynamics over the next three decades (2010-2040), in relation to the cholera surveillance operations over the past three decades (1980-2010). We find that an increased number of extreme precipitation events with prolonged dry periods in the Ganges basin region will likely adversely affect dry season cholera outbreaks. Increased monsoon precipitation volumes in the Brahmaputra basin catchments are likely to cause record floods and subsequently trigger large epidemics in downstream areas. Our results provide new insight by identifying the changes in the two distinctly different, pre and post monsoon, cholera transmission mechanisms related to large-scale climatic controls that prevail in the region.

    The ocean is a substantial source of nitrous oxide (N2O) to the atmosphere, but little is known on how this flux might change in the future. Here, we investigate the potential evolution of marine N2O emissions in the 21st century in response to anthropogenic climate change using the global ocean biogeochemical model NEMO-PISCES. We implemented two different parameterizations of N2O production, which differ primarily at low oxygen (O2) conditions. When forced with output from a climate model simulation run under the business-as-usual high CO2 concentration scenario (RCP8.5), our simulations suggest a decrease of 4 to 12% in N2O emissions from 2005 to 2100, i.e., a reduction from 4.03/3.71 to 3.54/3.56 Tg N yr-1 depending on the parameterization. The emissions decrease strongly in the western basins of the Pacific and Atlantic oceans, while they tend to increase above the Oxygen Minimum Zones (OMZs), i.e., in the Eastern Tropical Pacific and in the northern Indian Ocean. The reduction in N2O emissions is caused on the one hand by weakened nitrification as a consequence of reduced primary and export production, and on the other hand by stronger vertical stratification, which reduces the transport of N2O from the ocean interior to the ocean surface. The higher emissions over the OMZ are linked to an expansion of these zones under global warming, which leads to increased N2O production associated primarily with denitrification. From the perspective of a global climate system, the averaged feedback strength associated with the projected decrease in oceanic N2O emissions amounts to around -0.009 W m-2 K-1, which is comparable to the potential increase from terrestrial N2O sources. However, the assesment for a compensation between the terrestrial and marine feedbacks calls for an improved representation of N2O production terms in fully coupled next generation of Earth System Models.

  2. Stratospheric Ozone Predictions For The Late 21st Century

    Simulations of ozone evolution from 1960 until ~2100 from chemistry climate models (CCMs) that participated in CCMVal-2 are broadly consistent in that stratospheric ozone increases as chlorofluorcarbons decrease and the stratosphere cools (which affects the rate of temperature dependent loss processes), however, details of the projections vary significantly. Differences in the ozone response to specified changes in chlorine containing source gases dominate during the first half of the integrations. For example, from 1980 to 2000, chlorine change is by far the most important cause of ozone change, and the CCMs produce changes in the 60S-60N average column ozone that range between -3 DU and -17 DU. In the second half of the 21st century climate change is primarily responsible for ozone change. By 2080 the CCMs produce changes in the 60S-60N average upper stratospheric ozone column that range from 4 DU to 10 DU. The CCM range of differences is due to differences in both composition and upper stratospheric temperature. Ozone loss processes each have their own temperature sensitivity, and the net sensitivity of ozone to temperature change in each CCM depends on the relative importance of each loss process; this depends on the composition and temperature for the baseline atmosphere. In the lower stratosphere, climate change affects ozone evolution through changes in photochemical reaction rates due to stratospheric cooling and through circulation differences affecting transport of ozone and other trace gases. These are not separable using an approach such as multiple linear regression because changes in circulation and temperature have the same time dependence after accounting for contributions due to chlorine change. Recent attention has focused on similarity of the CCMs in that all predict a speed-up of the Brewer Dobson circulation. However, differences in the magnitude of the speed-up, differences in horizontal mixing and differences in the photochemical response to

    Recent environmental changes in the Arctic have clearly demonstrated that climate change is faster and more vigorously in the Polar Regions than anywhere else. Significantly, change in the Arctic Ocean (AO) environment presents a variety of impacts, from ecological to social-economic and political. Mitigation of this change and adaptation to it requires detailed and robust environmental predictions. Here we present a detailed projection of ocean circulation and sea ice from the present until 2099, based on an eddy-permitting high-resolution global simulation of the NEMO ¼ degree ocean model. The model is forced at the surface with HadGEM2-ES atmosphere model output from the UK Met. Office IPCC Assessment Report 5 (AR5) Representative Concentration Pathways 8.5 (RCP8.5) scenario. The HadGEM2-ES simulations span 1860-2099 and are one of an ensemble of runs performed for the Coupled Model Intercomparison Project 5 (CMIP5) and IPCC AR5. Between 2000-2009 and 2090-2099 the AO experiences a significant warming, with sea surface temperature increasing on average by about 4° C, particularly in the Barents and Kara Seas, and in the Greenland Sea and Hudson Bay. By the end of the simulation, Arctic sea ice has an average annual thickness of less than 10 cm in the central AO, and less than 0.5 m in the East-Siberian Sea and Canadian Archipelago, and disappears entirely during the Arctic summer. In summer, opening of large areas of the Arctic Ocean to the wind and surface waves leads to the Arctic pack ice cover evolving into the Marginal Ice Zone (MIZ). In winter, sea ice persists until the 2030s; then it sharply declines and disappears from the Central Arctic Ocean by the end of the 21st century, with MIZ provinces remaining in winter along the Siberian, Alaskan coasts and in the Canadian Arctic Archipelago. Analysis of the AO circulation reveals evidence of (i) the reversal of the Arctic boundary currents in the Canadian Basin, from a weak cyclonic current in 2040-2049 to

  11. Scenarios of Global Municipal Water-Use Demand Projections over the 21st Century

    This paper establishes three future projections of global municipal water use to the end of the 21st century: A reference business-as usual (BAU) scenario, a High Technological Improvement (High Tech) scenario and a Low Technological Improvement (Low Tech) scenario. A global municipal water demand model is constructed using global water use statistics at the country-scale, calibrated to the base year of 2005, and simulated to the end of the 21st century. Since the constructed water demand model hinges on socioeconomic variables (population, income), water price, and end-use technology and efficiency improvement rates, projections of those input variables are adopted to characterize the uncertainty in future water demand estimates. The water demand model is linked to the Global Change Assessment Model (GCAM), a global change integrated assessment model. Under the reference scenario, the global total water withdrawal increases from 466 km3/year in 2005 to 941 km3/year in 2100,while withdrawals in the high and low tech scenarios are 321 km3/ year and 2000 km3/ year, respectively. This wide range (321-2000 km3/ year) indicates the level of uncertainty associated with such projections. The simulated global municipal demand projections are most sensitive to population and income projections, then to end-use technology and efficiency projections, and finally to water price. Thus, using water price alone as a policy measure to reduce municipal water use may substantiate the share of municipal water price of people’s annual incomes.

    Recent advances in biological and computational technologies are changing the way different social groups imagine race, gender, kinship, citizenship and disease risk. Existing taxonomies are being displaced or reconfigured, impacting the ways in which people are governed, how lives are lived, how groups are known and how power is exercised. Herein we report on a two-day international symposium that we co-organized, titled 'The molecularization of identity: science and subjectivity in the 21st century,' that was held on 29-30 April 2016 at the Program on Science, Technology and Society, at Harvard University. The symposium drew upon the tools and expertise from multiple disciplines and diverse geographical regions and consisted of 24 original research presentations and an interdisciplinary roundtable. Specific attention was paid to the bioethical, material and lived dimensions of recent developments in molecular technologies, and discussions interrogated the complex ways in which the 'molecular realm' is an emerging site for constituting human identities in the 21st century. Herein we summarize some of the key findings of the conference and raise three further issues for practitioners and researchers to consider in relation to the broader impact of genetics research. Namely: transnational governance of emerging biotechnologies; representation of different interest groups in policy decisions; and rights of access to emerging technologies. PMID:27376979

    In the spring of 2009, I participated in PolarTREC - Teachers and Researchers Exploring and Collaborating, a Teacher Research Experience (TRE) funded by the National Science Foundation and managed by the Arctic Research Consortium of the United States. I assisted in hands-on research being performed by scientists with OASIS (Ocean, Atmosphere, Sea Ice and Snowpack) during their field campaign in Barrow, Alaska. Although I was in the field for only 3 weeks, it was merely a beginning to a transformation that took place not only in me, but also among all of those involved. The PolarTREC program embodies the principles fundamental to the 21st Century skill-set that we want our students to possess. The job market is changing for graduates, and education is striving to provide students with the skills necessary to thrive in the future. To ensure the success of students the International Society for Technology Education (ISTE) has defined 21st Century Skills. They are incorporated into many educational standards (such as the Arizona Educational Technology Standards) and they are practiced by the teachers, researchers, students and the PolarTREC community. They are:

    • Creativity and Innovation
    • Communication and Collaboration
    • Research and Information Literacy
    • Critical Thinking, Problem Solving, and Decision Making

      Summary Biomedical developments in the 21st century provide an unprecedented opportunity to gain a dynamic systems-level and human-specific understanding of the causes and pathophysiologies of disease. This understanding is a vital need, in view of continuing failures in health research, drug discovery, and clinical translation. The full potential of advanced approaches may not be achieved within a 20th-century conceptual framework dominated by animal models. Novel technologies are being integrated into environmental health research and are also applicable to disease research, but these advances need a new medical research and drug discovery paradigm to gain maximal benefits. We suggest a new conceptual framework that repurposes the 21st-century transition underway in toxicology. Human disease should be conceived as resulting from integrated extrinsic and intrinsic causes, with research focused on modern human-specific models to understand disease pathways at multiple biological levels that are analogous to adverse outcome pathways in toxicology. Systems biology tools should be used to integrate and interpret data about disease causation and pathophysiology. Such an approach promises progress in overcoming the current roadblocks to understanding human disease and successful drug discovery and translation. A discourse should begin now to identify and consider the many challenges and questions that need to be solved. PMID:26523530

    • Acidification of the Mediterranean Sea during the 21st century

      We modeled the carbon cycle in the Mediterranean Sea to study how its changes due to climate change and rising levels of atmospheric CO2 may differ from those typical of the global ocean. More specifically, we coupled offline an ocean biogeochemical model (PISCES) to a regional eddy-permitting model of the Mediterranean Sea (NEMO-MED8, 1/8° nominal horizonal resolution) using forcing from coupled regional climate model simulations of which the ocean circulation component was identical. Here we describe the simulated changes in pH and the associated carbonate system during the 21st century. Separate simulations were made with climate forcing for a hindcast (1965-2008) and for the future (2000-2100). For the former, climate and CO2 forcings were based on observations; for the latter, both climate and CO2 were driven by the IPCC SRES-A2 scenario. Our hindcast simulation over the period 1965-2008 allowed us to evaluate the model and assess recent variability of the carbonate system. In our future simulation, we used separate tracers to distinguish (1) the change due to climate change and the increase in atmospheric CO2 (from 370 to 800 ppm) and (2) the change due only to climate change (holding atmospheric CO2 to the year-2000 level of 370 ppm). By difference, we isolated the geochemical effect (anthropogenic CO2 perturbation). The hindcast simulation demonstrates that the model captures the amplitude and phase of the annual cycle of temperature, pCO2 and pH, in agreement with data from the DYFAMED station. That seasonal variability of surface pCO2 is everywhere driven by variations in temperature. These results lends support that the model is able to quantify the acidification of the Mediterranean Sea during the industrial period and for the future. However, they do not constrain the model's simulated effects of future climate change on ocean circulation and ocean biology, both of which in turn influence the carbon cycle.

      On Sunday morning, March 29, 1998, during the 215th American Chemical Society National Meeting in Dallas, TX, a special Presidential Event, "Challenges for Chemistry in the 21st Century", was held. It was sponsored by the American Chemical Society Committee on Science and Chemical and Engineering News as part of its 75th Anniversary. Six outstanding scientists spoke on the future of their chosen fields of study to a standing-room-only audience. The intensity and enthusiasm of these men and women were inspiring. Several common themes emerged. According to these experts, the next century will require greater education in science and technology for the public and greater emphasis on interdisciplinary approaches to science by scientists. The completion of the human genome project and technological advances, including the development of nanotechnology, will be the driving forces of research in chemistry.

    The evolution of stratospheric ozone from 1960 to 2100 is examined in simulations from 14 chemistry-climate models, driven by prescribed levels of halogens and greenhouse gases. There is general agreement among the models that total column ozone reached a minimum around year 2000 at all latitudes, projected to be followed by an increase over the first half of the 21st century. In the second half of the 21st century, ozone is projected to continue increasing, level off, or even decrease depending on the latitude. Separation into partial columns above and below 20 hPa reveals that these latitudinal differences are almost completely caused by differences in the model projections of ozone in the lower stratosphere. At all latitudes, upper stratospheric ozone increases throughout the 21st century and is projected to return to 1960 levels well before the end of the century, although there is a spread among models in the dates that ozone returns to specific historical values. We find decreasing halogens and declining upper atmospheric temperatures, driven by increasing greenhouse gases, contribute almost equally to increases in upper stratospheric ozone. In the tropical lower stratosphere, an increase in upwelling causes a steady decrease in ozone through the 21st century, and total column ozone does not return to 1960 levels in most of the models. In contrast, lower stratospheric and total column ozone in middle and high latitudes increases during the 21st century, returning to 1960 levels well before the end of the century in most models.

    Natural products and related structures are essential sources of new pharmaceuticals, because of the immense variety of functionally relevant secondary metabolites of microbial and plant species. Furthermore, the development of powerful analytical tools based upon genomics, proteomics, metabolomics, bioinformatics and other 21st century technologies are greatly expediting identification and characterization of these natural products. Here we discuss the synergistic and reciprocal benefits of linking these 'omics technologies with robust ethnobotanical and ethnomedical studies of traditional medicines, to provide critically needed improved medicines and treatments that are inexpensive, accessible, safe and reliable. However, careless application of modern technologies can challenge traditional knowledge and biodiversity that are the foundation of traditional medicines. To address such challenges while fulfilling the need for improved (and new) medicines, we encourage the development of Regional Centres of 'omics Technologies functionally linked with Regional Centres of Genetic Resources, especially in regions of the world where use of traditional medicines is prevalent and essential for health.

    The United States' experience with a deterrent security strategy is colored by more than 40 years of confrontation with the Soviet Union. Over the Cold War years, American political leadership wrestled with two foreign policy challenges: the threat of communist expansion and the danger of nuclear weapons. With the dissolution of the Soviet Union, communist expansion may be a thing of the past. Nevertheless, nuclear weapons are still with us in large numbers. Of the many challenges facing American statecraft in the 21st century, few are as foreboding as the accelerating proliferation of nuclear weapons and the means for their delivery. Although intelligence professionals cannot confidently predict the 21st century international environment, several trends characterize what we might find. There will still be ideological competitors, in some cases involved in intractable regional conflicts. Furthermore, nuclear and conventional military technologies will increasingly spread, militarizing old regional battles. As new nuclear regimes emerge, their political calculations will be tempered by these longstanding animosities, possibly escalating lower order regional violence to nuclear confrontation. The United States must address the significant issues raised by growing regional nuclear potential adversaries if it expects to influence the international order required to achieve the National Security Strategy's envisioned Age of Democratic Peace.

  5. Hotter days and droughts to continue through the 21st century

    As heat waves become more frequent and droughts cause famines and drive up food prices, climate policies will need to account for changes in extremes in temperature and precipitation, as global mean temperatures continue to rise through the 21st century. Using HadGEM2, a new ocean-atmosphere coupled climate model, Caesar and Lowe investigated the effects of different greenhouse gas emissions scenarios on maximum and minimum air temperatures as well as on the amounts of rainfall in different parts of the world. The authors compared two scenarios through the 21st century, the first one with an aggressive mitigation scenario, in which global emissions begin to decrease in the early 21st century and reach nearly zero by 2100; the second scenario had no mitigation. The researchers' results show that extreme temperatures would scale with increasing mean temperature, at least until the middle of the 21st century: As air temperatures increase, countries across the globe would experience hotter days and an increasing number of heat waves, even with aggressive mitigation. However, mitigation may provide some amelioration, particularly through the second half of the 21st century; the northern midlatitudes would benefit most from mitigation measures, although northern South America and parts of the United States, Africa, and Asia could also avoid large increases in extreme temperature maxima by following similar mitigation policies.

    Command, Control and Communications (CCC) has evolved through the years from simple switches, dials, analogue hardwire networks and lights to a modern computer based digital network. However there are two closely coupled pillars upon which a CCC system is built. The first, is that technology drives the pace of advancement. The second is that a culture that fosters resistance to change can limit technological advancements in the CCC system. While technology has advanced at a tremendous rate throughout the years, the change in culture has moved slowly. This paper will attempt to show through a historical perspective where specific design decisions for early CCC systems have erroneously evolved into general requirements being imposed on later systems. Finally this paper will provide a glimpse into the future directions envisioned for CCC capabilities that will enable 21st century missions.

    In the 1960s there were large-scale concerns about the world's ability to feed itself. However, widespread adoption of "green revolution" technology led to major increases in food-grain production. Between 1966 and 1990, the population of the densely populated low-income countries grew by 80%, but food production more than doubled. The technological advance that led to the dramatic achievements in world food production over the last 30 years was the development of high-yielding varieties of wheat and rice. These varieties are responsive to fertilizer inputs, are lodging resistant, and their yield potential is 2-3 times that of varieties available prior to the green revolution. In addition, these varieties have multiple resistance to diseases and insects and thus have yield stability. The development of irrigation facilities, the availability of inorganic fertilizers, and benign government policies have all facilitated the adoption of green-revolution technology. In the 1990s, the rate of growth in food-grain production has been lower than the rate of growth in population. If this trend is not reversed, serious food shortages will occur in the next century. To meet the challenge of feeding 8 billion people by 2020, we have to prepare now and develop the technology for raising farm productivity. We have to develop cereal cultivars with higher yield potential and greater yield stability. We must also develop strategies for integrated nutrient management, integrated pest management, and efficient utilization of water and soil resources. PMID:10464789

    Scenarios are a useful way to make responsible officials think hard about the future. For officials in the Department of Defense, some of these scenarios must consider the actual use of nuclear weapons, so that they will be better prepared to avoid such situations. To encourage breadth in the formulation of games for official purposes, RAND responded to a request from the Director of Net Assessment to create a number of scenarios for the early 21st century in which conflict would occur or be likely and in which due attention would be given to the political and technological conditions that might then be operational. This Note presents a wide range of such scenarios in sketch form. Several of the scenarios assume varying degrees of success for elements of the current Strategic Defense Initiative program, for new applications of stealth technology, for the National Aerospace Plane, for nonnuclear strategic weapons, and for new surveillance techniques. Applications range from battlefield uses to strategic options.

    1996-01-01

    Space Technology has been rapidly increasing in the past decade. This can be attributed to the future construction of the International Space Station (ISS). New innovations must constantly be engineered to make ISS the safest, quality, research facility in space. Since space science must often be gathered by crew members, more attention must be geared to the human's safety and comfort. Virtual simulations are now being used to design environments that crew members can live in for long periods of time without harmful effects to their bodies. This paper gives a few examples of the ergonomic design problems that arise on manned space flights, and design solutions that follow NASA's strategic commitment to customer satisfaction. The conclusions show that virtual simulations are a great asset to 21st century design.

  13. New Approaches to Providing Individualized Diabetes Care in the 21st Century

    Building from a foundation of rapid innovation, the 21st century is poised to offer considerable new approaches to providing modern diabetes care. The focus of this paper is the evolving role of diabetes care providers collaboratively working with patients and families toward the goals of achieving optimal clinical and psychosocial outcomes for individuals living with diabetes. Advances in monitoring, treatment and technology have been complemented by trends toward patient-centered care with expertise from multiple health care disciplines. The evolving clinical care delivery system extends far beyond adjustment of insulin regimens. Effective integration of patient-centered strategies, such as shared-decision making, motivational interviewing techniques, shared medical appointments, and multidisciplinary team collaboration, into a dynamic model of diabetes care delivery holds promise in reaching glycemic targets and improving patients’ quality of life.

  15. Treating Parkinson's disease in the 21st century: can stem cell transplantation compete?

    Buttery, Philip C; Barker, Roger A

    2014-08-15

    The characteristic and selective degeneration of a unique population of cells-the nigrostriatal dopamine (DA) neurons-that occurs in Parkinson's disease (PD) has made the condition an iconic target for cell replacement therapies. Indeed, transplantation of fetal ventral mesencephalic cells into the DA-deficient striatum was first trialled nearly 30 years ago, at a time when other treatments for the disease were less well developed. Over recent decades standard treatments for PD have advanced, and newer biological therapies are now emerging. In the 21st century, stem cell technology will have to compete alongside other sophisticated treatments, including deep brain stimulation and gene therapies. In this review we examine how stem cell-based transplantation therapies compare with these novel and emerging treatments in the management of this common condition. J. Comp.

  16. Advanced Capabilities for Wind Tunnel Testing in the 21st Century

    NASA Technical Reports Server (NTRS)

    Kegelman, Jerome T.; Danehy, Paul M.; Schwartz, Richard J.

    2010-01-01

    Wind tunnel testing methods and test technologies for the 21st century using advanced capabilities are presented. These capabilities are necessary to capture more accurate and high quality test results by eliminating the uncertainties in testing and to facilitate verification of computational tools for design. This paper discusses near term developments underway in ground testing capabilities, which will enhance the quality of information of both the test article and airstream flow details. Also discussed is a selection of new capability investments that have been made to accommodate such developments. Examples include advanced experimental methods for measuring the test gas itself; using efficient experiment methodologies, including quality assurance strategies within the test; and increasing test result information density by using extensive optical visualization together with computed flow field results. These points could be made for both major investments in existing tunnel capabilities or for entirely new capabilities.

  19. Future dryness in the southwest US and the hydrology of the early 21st century drought.

    2010-12-14

    Recently the Southwest has experienced a spate of dryness, which presents a challenge to the sustainability of current water use by human and natural systems in the region. In the Colorado River Basin, the early 21st century drought has been the most extreme in over a century of Colorado River flows, and might occur in any given century with probability of only 60%. However, hydrological model runs from downscaled Intergovernmental Panel on Climate Change Fourth Assessment climate change simulations suggest that the region is likely to become drier and experience more severe droughts than this. In the latter half of the 21st century the models produced considerably greater drought activity, particularly in the Colorado River Basin, as judged from soil moisture anomalies and other hydrological measures. As in the historical record, most of the simulated extreme droughts build up and persist over many years. Durations of depleted soil moisture over the historical record ranged from 4 to 10 years, but in the 21st century simulations, some of the dry events persisted for 12 years or more. Summers during the observed early 21st century drought were remarkably warm, a feature also evident in many simulated droughts of the 21st century. These severe future droughts are aggravated by enhanced, globally warmed temperatures that reduce spring snowpack and late spring and summer soil moisture. As the climate continues to warm and soil moisture deficits accumulate beyond historical levels, the model simulations suggest that sustaining water supplies in parts of the Southwest will be a challenge.
