Creating wealth from groundwater for dollar-a-day farmers: Where the silent revolution and the four revolutions to end rural poverty meet

NASA Astrophysics Data System (ADS)

Polak, Paul; Yoder, Robert

2006-03-01

More than 550 million of the current 1.1 billion people earning less than 1-a-day earn a living from agriculture in developing countries. A revolution in water control is needed to develop and mass-disseminate new, affordable, small-plot irrigation technologies. A revolution in agriculture is required to enable smallholders to produce high-value, marketable, labor-intensive cash crops. A revolution in markets is needed to open access to markets for the crops they produce and the inputs they need to produce them. Finally, a revolution in design, based on the ruthless pursuit of affordability, is needed to harness shallow groundwater. The experiences of suppliers of treadle pumps, low-cost drip irrigation and water storage systems were examined. The wealth these technologies generated, coupled with falling prices for small diesel pumps in countries like India and China, created a suitable environment for the rapid adoption of affordable diesel pump tubewells, which in turn created vigorous water markets and expanded access to affordable irrigation water for smallholders. The combination of smallholder-centered revolutions, along with the ‘silent revolution in groundwater’ described by Llamas and Martinez-Santos (Water Sci Technol 51(8):167-174, 2005) provide new practical options for meeting the UN Millennium Development Goals on poverty and hunger by 2015.

Intelligent hearing aids: the next revolution.

Tao Zhang; Mustiere, Fred; Micheyl, Christophe

2016-08-01

The first revolution in hearing aids came from nonlinear amplification, which allows better compensation for both soft and loud sounds. The second revolution stemmed from the introduction of digital signal processing, which allows better programmability and more sophisticated algorithms. The third revolution in hearing aids is wireless, which allows seamless connectivity between a pair of hearing aids and with more and more external devices. Each revolution has fundamentally transformed hearing aids and pushed the entire industry forward significantly. Machine learning has received significant attention in recent years and has been applied in many other industries, e.g., robotics, speech recognition, genetics, and crowdsourcing. We argue that the next revolution in hearing aids is machine intelligence. In fact, this revolution is already quietly happening. We will review the development in at least three major areas: applications of machine learning in speech enhancement; applications of machine learning in individualization and customization of signal processing algorithms; applications of machine learning in improving the efficiency and effectiveness of clinical tests. With the advent of the internet of things, the above developments will accelerate. This revolution will bring patient satisfactions to a new level that has never been seen before.

Revolutions in Neuroscience: Tool Development

PubMed Central

Bickle, John

2016-01-01

Thomas Kuhn’s famous model of the components and dynamics of scientific revolutions is still dominant to this day across science, philosophy, and history. The guiding philosophical theme of this article is that, concerning actual revolutions in neuroscience over the past 60 years, Kuhn’s account is wrong. There have been revolutions, and new ones are brewing, but they do not turn on competing paradigms, anomalies, or the like. Instead, they turn exclusively on the development of new experimental tools. I adopt a metascientific approach and examine in detail the development of two recent neuroscience revolutions: the impact of engineered genetically mutated mammals in the search for causal mechanisms of “higher” cognitive functions; and the more recent impact of optogenetics and designer receptors exclusively activated by designer drugs (DREADDs). The two key metascientific concepts, I derive from these case studies are a revolutionary new tool’s motivating problem, and its initial and second-phase hook experiments. These concepts hardly exhaust a detailed metascience of tool development experiments in neuroscience, but they get that project off to a useful start and distinguish the subsequent account of neuroscience revolutions clearly from Kuhn’s famous model. I close with a brief remark about the general importance of molecular biology for a current philosophical understanding of science, as comparable to the place physics occupied when Kuhn formulated his famous theory of scientific revolutions.

The dual Green Revolutions in South Korea: reforestation and agricultural revolution under the authoritarian regime.

PubMed

Moon, Manyong

2012-01-01

In South Korea, the Green Revolution has been commonly understood as the development and dissemination of new rice varieties ('Tongil' rice) and the rapid increase of rice yield in the 1970s. However, revolutionary success in agriculture was not the only green revolution South Korea experienced; another green revolution lay in the success of reforestation projects. In the 1970s, South Korea's forest greening was closely related to its agricultural revolution in several ways. Therefore, South Korea's Green Revolution was an intrinsically linked double feature of agriculture and forestry. This two-pronged revolution was initiated by scientific research - yet accomplished by the strong administrative mobilization of President Park Chung Hee's regime. The process of setting goals and meeting them through a military-like strategy in a short time was made possible under the authoritarian regime, known as 'Yushin', though the administration failed to fully acknowledge scientific expertise in the process of pushing to achieve goals.

Revolutions in the earth sciences

PubMed Central

Allègre, C.

1999-01-01

The 20th century has been a century of scientific revolutions for many disciplines: quantum mechanics in physics, the atomic approach in chemistry, the nonlinear revolution in mathematics, the introduction of statistical physics. The major breakthroughs in these disciplines had all occurred by about 1930. In contrast, the revolutions in the so-called natural sciences, that is in the earth sciences and in biology, waited until the last half of the century. These revolutions were indeed late, but they were no less deep and drastic, and they occurred quite suddenly. Actually, one can say that not one but three revolutions occurred in the earth sciences: in plate tectonics, planetology and the environment. They occurred essentially independently from each other, but as time passed, their effects developed, amplified and started interacting. These effects continue strongly to this day.

1996-01-01

Sexual development and behavior of 771 Czech girls 16 to 18 years old had been investigated by two sexuologists during the period of 1986 till 1994. A standardized interview of 78 items had been applied in a setting of a rehabilitation facility in Franzensbad. The majority of probands were there for rehabilitation after appendectomy. There were 389 examinees (158 apprentices and 231 students) interviewed before "the velvet revolution" and 382 girls (159 apprentices and 223 students) in the course of the years 1990 to 1994. A comparison of these two groups revealed a definite change in the psychosexual development of girls in the Czech society after the "Velvet Revolution". Particularly the motivation for the first coitus had changed. After November 1989 it was noticed that the answer "obliged her partner" had significantly decreased and the answer "wished it for myself" has substantially increased. Also in the group of probands with multiple sexual partners (21.5% of the sample) their average number decreased unexpectedly after "the Velvet Revolution".

Publishing descriptions of non-public clinical datasets: proposed guidance for researchers, repositories, editors and funding organisations.

PubMed

Hrynaszkiewicz, Iain; Khodiyar, Varsha; Hufton, Andrew L; Sansone, Susanna-Assunta

2016-01-01

Sharing of experimental clinical research data usually happens between individuals or research groups rather than via public repositories, in part due to the need to protect research participant privacy. This approach to data sharing makes it difficult to connect journal articles with their underlying datasets and is often insufficient for ensuring access to data in the long term. Voluntary data sharing services such as the Yale Open Data Access (YODA) and Clinical Study Data Request (CSDR) projects have increased accessibility to clinical datasets for secondary uses while protecting patient privacy and the legitimacy of secondary analyses but these resources are generally disconnected from journal articles-where researchers typically search for reliable information to inform future research. New scholarly journal and article types dedicated to increasing accessibility of research data have emerged in recent years and, in general, journals are developing stronger links with data repositories. There is a need for increased collaboration between journals, data repositories, researchers, funders, and voluntary data sharing services to increase the visibility and reliability of clinical research. Using the journal Scientific Data as a case study, we propose and show examples of changes to the format and peer-review process for journal articles to more robustly link them to data that are only available on request. We also propose additional features for data repositories to better accommodate non-public clinical datasets, including Data Use Agreements (DUAs).

The wide-spread prevalence of unimproved sanitation technologies has been a major cause of concern for the environment and public health, and China is no exception to this. Towards the sanitation issue, toilet revolution has become a buzzword in China recently. This paper elaborates the backgrounds, connotations, and actions of the toilet revolution in China. The toilet revolution aims to create sanitation infrastructure and public services that work for everyone and that turn waste into value. Opportunities for implementing the toilet revolution include: fulfilling Millennium Development Goals and new Sustainable Development Goals; government support at all levels for popularizing sanitary toilet; environmental protection to alleviate wastewater pollution; resource recovery from human waste and disease prevention for health and wellbeing improvement. Meanwhile, the challenges faced are: insufficient funding and policy support, regional imbalance and lagging approval processes, weak sanitary awareness and low acceptance of new toilets, lack of R&D and service system. The toilet revolution requires a concerted effort from many governmental departments. It needs to address not only technology implementation, but also social acceptance, economic affordability, maintenance issues and, increasingly, gender considerations. Aligned with the ecological sanitation principles, it calls for understanding issues across the entire sanitation service chain. Public-private partnership is also recommended to absorb private capital to make up the lack of funds, as well as arouse the enthusiasm of the public. Copyright © 2017 The Authors.

Barefoot Doctors and the "Health Care Revolution" in Rural China: A Study Centered on Shandong Province.

PubMed

Xu, Sanchun; Hu, Danian

2017-09-01

Barefoot doctors were rural medical personnel trained en masse, whose emergence and development had a particular political, economic, social, and cultural background. Like the rural cooperative medical care system, the barefoot doctor was a well-known phenomenon in the Cultural Revolution. Complicated regional differences and a lack of reliable sources create much difficulty for the study of barefoot doctors and result in differing opinions of their status and importance. Some scholars greatly admire barefoot doctors, whereas others harshly criticize them. This paper explores the rise and development of barefoot doctors based on a case study of Shandong province. I argue that the promotion of barefoot doctors was a consequence of the medical education revolution and an implementation of the Cultural Revolution in rural public health care, which significantly influenced medical services and development in rural areas. First, barefoot doctors played a significant role in accomplishing the first rural health care revolution by providing primary health care to peasants and eliminating endemic and infectious illnesses. Second, barefoot doctors were the agents who integrated Western and Chinese medicines under the direction of the state. As an essential part of the rural cooperative medical system, barefoot doctor personnel grew in number with the system's implementation. After the Cultural Revolution ended, the cooperative medical system began to disintegrate-a process that accelerated in the 1980s until the system's collapse in the wake of the de-collectivization. As a result, the number of barefoot doctors also ran down steadily. In 1985, "barefoot doctor" as a job title was officially removed from Chinese medical profession, demonstrating that its practice was non-universal and unsustainable. Copyright © 2017 Elsevier Ltd.

Perception of emotional climate in a revolution: Test of a multistage theory of revolution in the Tunisian context.

PubMed

Rimé, Bernard; Yzerbyt, Vincent; Mahjoub, Abdelwahab

2017-12-01

Participation in social movements and collective action depends upon people's capacity to perceive their societal context. We examined this question in the context of Arab Spring revolutions. In a classic theory of revolution highlighting the role of collective emotions, Brinton (1938) claimed that revolutions, far from chaos, proceed in an orderly sequence involving four stages: euphoria, degradation, terror, and restoration. The emotional climate (EC) as perceived by ordinary Tunisian citizens (2,699 women and 3,816 men) was measured during the 4 years of the Tunisian revolution. A quadratic pattern of perceived EC measures over time provided strong support to Brinton's model. In addition, three different analyses suggested the presence of four distinct stages in the evolution of perceived EC. Third, the socio-political developments in Tunisia during the four stages proved entirely consistent with both Brinton's theoretical model and the perceived EC indicators. Finally, social identification proved closely related to the temporal evolution of positive EC scores. In sum, data from this study not only lend support to the views put forth in an heretofore untested classic theory of revolution but also demonstrate that psychosocial measurements can validly monitor a major process of socio-political transformation. © 2017 The British Psychological Society.

Cover beds older than the mid-pleistocene revolution and the provenance of their eolian components, La Sal Mountains, Utah, USA

NASA Astrophysics Data System (ADS)

Krautz, Jana; Gärtner, Andreas; Hofmann, Mandy; Linnemann, Ulf; Kleber, Arno

2018-04-01

We used uranium-lead (U-Pb) dating of zircons from a tephra layer deposited in the La Sal Mountains to assign an age of more than c. 1.3 Ma to underlying loess-mixed slope deposits (cover beds) and paleosols developed therein. For the first time, we show that properties of cover beds and soils before the Mid-Pleistocene Revolution were similar to those formed after the revolution. However, the deepest exposed carbonate-enriched horizon is much farther developed than younger ones, indicating that there was a period of enrichment by far exceeding intensities of younger calcic horizons some time before the revolution, possibly in Neogene times. Remarkable differences between age distributions of detrital zircons (DZ) within the cover beds allow reconstructing the regional provenance of mixed eolian matter with high accuracy: we were able to trace particular cover beds back to areas with outcropping Permian and Upper Cretaceous rocks.

Understanding the Dynamics of Violent Political Revolutions in an Agent-Based Framework.

Moro, Alessandro

2016-01-01

This paper develops an agent-based computational model of violent political revolutions in which a subjugated population of citizens and an armed revolutionary organisation attempt to overthrow a central authority and its loyal forces. The model replicates several patterns of rebellion consistent with major historical revolutions, and provides an explanation for the multiplicity of outcomes that can arise from an uprising. The relevance of the heterogeneity of scenarios predicted by the model can be understood by considering the recent experience of the Arab Spring involving several rebellions that arose in an apparently similar way, but resulted in completely different political outcomes: the successful revolution in Tunisia, the failed protests in Saudi Arabia and Bahrain, and civil war in Syria and Libya.

The Nineteenth-Century Revolution in Astronomy

NASA Astrophysics Data System (ADS)

Batten, Alan Henry

2015-08-01

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

The epistemology of mathematical and statistical modeling: a quiet methodological revolution.

PubMed

Rodgers, Joseph Lee

2010-01-01

A quiet methodological revolution, a modeling revolution, has occurred over the past several decades, almost without discussion. In contrast, the 20th century ended with contentious argument over the utility of null hypothesis significance testing (NHST). The NHST controversy may have been at least partially irrelevant, because in certain ways the modeling revolution obviated the NHST argument. I begin with a history of NHST and modeling and their relation to one another. Next, I define and illustrate principles involved in developing and evaluating mathematical models. Following, I discuss the difference between using statistical procedures within a rule-based framework and building mathematical models from a scientific epistemology. Only the former is treated carefully in most psychology graduate training. The pedagogical implications of this imbalance and the revised pedagogy required to account for the modeling revolution are described. To conclude, I discuss how attention to modeling implies shifting statistical practice in certain progressive ways. The epistemological basis of statistics has moved away from being a set of procedures, applied mechanistically, and moved toward building and evaluating statistical and scientific models.

Green revolution: preparing for the 21st century.

PubMed

Khush, G S

1999-08-01

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.

From satellite altimetry to Argo and operational oceanography: three revolutions in oceanography

NASA Astrophysics Data System (ADS)

Le Traon, P. Y.

2013-10-01

The launch of the French/US mission Topex/Poseidon (T/P) (CNES/NASA) in August 1992 was the start of a revolution in oceanography. For the first time, a very precise altimeter system optimized for large-scale sea level and ocean circulation observations was flying. T/P alone could not observe the mesoscale circulation. In the 1990s, the ESA satellites ERS-1/2 were flying simultaneously with T/P. Together with my CLS colleagues, we demonstrated that we could use T/P as a reference mission for ERS-1/2 and bring the ERS-1/2 data to an accuracy level comparable to T/P. Near-real-time high-resolution global sea level anomaly maps were then derived. These maps have been operationally produced as part of the SSALTO/DUACS system for the last 15 yr. They are now widely used by the oceanographic community and have contributed to a much better understanding and recognition of the role and importance of mesoscale dynamics. Altimetry needs to be complemented with global in situ observations. At the end of the 90s, a major international initiative was launched to develop Argo, the global array of profiling floats. This has been an outstanding success. Argo floats now provide the most important in situ observations to monitor and understand the role of the ocean on the earth climate and for operational oceanography. This is a second revolution in oceanography. The unique capability of satellite altimetry to observe the global ocean in near-real-time at high resolution and the development of Argo were essential for the development of global operational oceanography, the third revolution in oceanography. The Global Ocean Data Assimilation Experiment (GODAE) was instrumental in the development of the required capabilities. This paper provides an historical perspective on the development of these three revolutions in oceanography which are very much interlinked. This is not an exhaustive review and I will mainly focus on the contributions we made together with many colleagues and friends.

Blade resonance parameter identification based on tip-timing method without the once-per revolution sensor

NASA Astrophysics Data System (ADS)

Guo, Haotian; Duan, Fajie; Zhang, Jilong

2016-01-01

Blade tip-timing is the most effective method for blade vibration online measurement of turbomachinery. In this article a synchronous resonance vibration measurement method of blade based on tip-timing is presented. This method requires no once-per revolution sensor which makes it more generally applicable in the condition where this sensor is difficult to install, especially for the high-pressure rotors of dual-rotor engines. Only three casing mounted probes are required to identify the engine order, amplitude, natural frequency and the damping coefficient of the blade. A method is developed to identify the blade which a tip-timing data belongs to without once-per revolution sensor. Theoretical analyses of resonance parameter measurement are presented. Theoretic error of the method is investigated and corrected. Experiments are conducted and the results indicate that blade resonance parameter identification is achieved without once-per revolution sensor.

Hacking the quantum revolution: 1925-1975

NASA Astrophysics Data System (ADS)

Schweber, Silvan S.

2015-01-01

I argue that the quantum revolution should be seen as an Ian Hacking type of scientific revolution: a profound, longue durée, multidisciplinary process of transforming our understanding of physical nature, with deep-rooted social components from the start. The "revolution" exhibits a characteristic style of reasoning - the hierarchization of physical nature - and developed and uses a specific language - quantum field theory (QFT). It is by virtue of that language that the quantum theory has achieved some of its deepest insights into the description of the dynamics of the physical world. However, the meaning of what a quantum field theory is and what it describes has deeply altered, and one now speaks of "effective" quantum field theories. Interpreting all present day quantum field theories as but "effective" field theories sheds additional light on Phillip Anderson's assertion that "More is different". This important element is addressed in the last part of the paper.

Design of a Minimum Surface-Effect Three Degree-of-Freedom Micromanipulator

NASA Technical Reports Server (NTRS)

Goldfarb, Michael; Speich, John E.

1997-01-01

This paper describes the fundamental physical motivations for small-scale minimum surface-effect design, and presents a three degree-of-freedom micromanipulator design that incorporates a minimum surface-effect approach. The primary focus of the design is the split-tube flexure, a unique small-scale revolute joint that exhibits a considerably larger range of motion and significantly better multi-axis revolute joint characteristics than a conventional flexure. The development of this joint enables the implementation of a small-scale spatially-loaded revolute joint-based manipulator with well-behaved kinematic characteristics and without the backlash and stick-slip behavior that would otherwise prevent precision control

Supermarket revolution in Asia and emerging development strategies to include small farmers.

PubMed

Reardon, Thomas; Timmer, C Peter; Minten, Bart

2012-07-31

A "supermarket revolution" has occurred in developing countries in the past 2 decades. We focus on three specific issues that reflect the impact of this revolution, particularly in Asia: continuity in transformation, innovation in transformation, and unique development strategies. First, the record shows that the rapid growth observed in the early 2000s in China, Indonesia, Malaysia, and Thailand has continued, and the "newcomers"--India and Vietnam--have grown even faster. Although foreign direct investment has been important, the roles of domestic conglomerates and even state investment have been significant and unique. Second, Asia's supermarket revolution has exhibited unique pathways of retail diffusion and procurement system change. There has been "precocious" penetration of rural towns by rural supermarkets and rural business hubs, emergence of penetration of fresh produce retail that took much longer to initiate in other regions, and emergence of Asian retail developing-country multinational chains. In procurement, a symbiosis between modern retail and the emerging and consolidating modern food processing and logistics sectors has arisen. Third, several approaches are being tried to link small farmers to supermarkets. Some are unique to Asia, for example assembling into a "hub" or "platform" or "park" the various companies and services that link farmers to modern markets. Other approaches relatively new to Asia are found elsewhere, especially in Latin America, including "bringing modern markets to farmers" by establishing collection centers and multipronged collection cum service provision arrangements, and forming market cooperatives and farmer companies to help small farmers access supermarkets.

The Council of Europe's legal regulation concerning development of biology and medicine undoubtedly form the most interesting, but certainly not perfect, over-national system of protection of human beings in prenatal stages of development. The strength of the mentioned system is that it based on well-known and common acceptable values and rules such as human dignity and its protection. The aim of the paper is to present the reasons behind adopting such a system, as well as the consequences of the latter.The author argues that in such a way a revolution within the human rights system of the Council of Europe took place. This revolution caused a significant expansion of the Council of Europe's system of human rights' protection and changed the perspective of the protection from vertical to the horizontal.

Revolution, Modernity and (Trans)National Shi`i Islam: Rethinking Religious Conversion in Senegal

Leichtman, Mara A.

2013-01-01

The establishment of a Shi`i Islamic network in Senegal is one alternative to following the country's dominant Sufi orders. I examine Senegalese conversion narratives and the central role played by the Iranian Revolution, contextualizing life stories (trans)nationally in Senegal's political economy and global networks with Iran and Lebanon. Converts localize foreign religious ideologies into a ‘national’ Islam through the discourse that Shi`i education can bring peace and economic development to Senegal. Senegalese Shi`a perceive that proselytizing, media technologies, and Muslim networking can lead to social, cultural and perhaps even political change through translating the Iranian Revolution into a non-violent reform movement.

Microelectronics Revolution And The Impact Of Automation In The New Industrialized Countries

NASA Astrophysics Data System (ADS)

Baranauskas, Vitor

1984-08-01

A brief review of some important historical points on the origin of the Factories and the Industrial Revolution is presented with emphasis in the social problems related to the automation of the human labor. Until the World War I, the social changes provoked by the Industrial Revolution caused one division of the World in developed and underdeveloped countries. After that period, the less developed nations began their industrialization mainly through the Multinationals Corporations (MC). These enterprises were very important to the production and exportation of utilities and manufactures in general, mainly in those products which required intensive and direct human labor. At present time, with the pervasiveness of microelectronics in the automation, this age seems to reaching an end because all continous processes in industry tend economicaly toward total automation. This fact will cause a retraction in long-term investments and, beyond massive unemployment, there is a tendency for these MC industries to return to their original countries. The most promising alternative to avoid these events, and perhaps the unique, is to incentive an autonomous development in areas of high technology, as for instance, the microelectronics itself.

Compact type-I coil planet centrifuge for counter-current chromatography

PubMed Central

Yang, Yi; Gu, Dongyu; Liu, Yongqiang; Aisa, Haji Akber; Ito, Yoichiro

2009-01-01

A compact type-I coil planet centrifuge has been developed for performing counter-current chromatography. It has a revolution radius of 10 cm and a column holder height of 5 cm compared with 37 cm and 50 cm in the original prototype, respectively. The reduction in the revolution radius and column length permits application of higher revolution speed and more stable balancing of the rotor which leads us to learn more about its performance and the future potential of type-I coil planet centrifuge. The chromatographic performance of this apparatus was evaluated in terms of retention of the stationary phase (Sf), peak resolution (Rs), theoretical plate (N) and peak retention time (tR). The results of the experiment indicated that increasing the revolution speed slightly improved both the retention of the stationary phase and the peak resolution while the separation time is remarkably shortened to yield an excellent peak resolution at a revolution speed of 800 rpm. With a 12 ml capacity coiled column, DNP-glu, DNP-β-ala and DNP-ala were resolved at Rs of 2.75 and 2.16 within 90 min at a flow rate of 0.4 ml/min. We believe that the compact type-I coil planet centrifuge has a high analytical potential. PMID:20060979

Was there a Darwinian Revolution? Yes, no, and maybe!

PubMed

Ruse, Michael

2014-01-01

Was there a Darwinian Revolution and was it but part of the Scientific Revolution? Before Thomas Kuhn's Structure of Scientific Revolutions in 1962, most people thought that there was a Darwinian Revolution, that it was in some sense connected to the Scientific Revolution, but that neither question nor answer was terribly interesting. Then revolutions in science became a matter of intense debate, not so much about their very existence but about their nature. Was there a switch in world-views? Did the facts change? What was the importance of social groups? And so forth. Recently however some students of the history of science have started to argue that the very questions are misconceived and that there cannot have been a Darwinian Revolution and its relationship to the Scientific Revolution is imaginary because there are no such revolutions in science! This paper takes a sympathetic look at these issues, concluding that there is still life in the revolution-in-science issue, that Kuhn's book was seminal and still has things of importance to say, but that matters are more complex and more interesting than we thought back then.

Teacher Professional Development that Makes an Impact

NASA Astrophysics Data System (ADS)

Borrego, H.; Ellins, K. K.

2012-12-01

Through four years of participation in the TeXas Earth and Space Science (TXESS) Revolution, an NSF-sponsored teacher professional development project, my knowledge of earth science and new pedagogical approaches has improved dramatically. In addition, I have received instructional materials, and learned how to access high quality online resources and use a variety of web-based tools. As a consequence, I have developed the confidence to use the TXESS model to deliver earth science professional development that makes an impact to other teachers in the Rio Grande Valley region of South Texas. In this session, I will share my experiences as an earth science professional development provider and describe how I have used my own learning to help both teachers and students become more earth science literate. Earth science test scores at the elementary and secondary level throughout South Texas are consistently low in comparison to other regional areas in the state. The majority of the teachers lack the content-knowledge, confidence, or experience to teach earth science. My background as teacher combined with the TXESS Revolution experience helped me to understand the needs of these teachers and to identify teaching resources that would be useful to them. Using educational resources provided by the TXESS Revolution I have offered professional development topics such as Energy, Geologic Time and Stratigraphy, Water and the Cryosphere, Plate Tectonics, and Climate to about 125 South Texas elementary and middle school teachers. These trainings have helped improve the content knowledge of South Texas teachers and given them tools that they can use to guide student learning through authentic scientific research. In addition to providing professional development to teachers, I have been recruited to serve as the representative of the Offshore Energy Center for South Texas. This curriculum complements the TXESS Revolution educational resources by expanding the Energy education. The partnership with Offshore Energy is financing the framework for developing more training. More than 15 school districts in South Texas will have the opportunity to participate in this program

Thomas Kuhn's description and characterization of scientific revolutions set the standard for interpreting and understanding these events, but his characterization introduced an anomaly. Newtonian science was at the pinnacle of its success immediately prior to the Second Scientific Revolution. From an evolutionary point-of-view, there were no crises to be solved just problems within the Newtonian paradigm, whereas the specific crises that initiated the revolution are evident from everyone's point-of-view after the revolution. This paradox is well recognized, but it seems not to be a problem and is just ignored as if it were not important or significant. Yet this discrepancy strikes at the very heart of physics and the overall progress of science. Historical conditions currently parallel the period immediately prior to the Second Scientific Revolution indicating that a new scientific revolution is approaching. When a comparison of the two periods is made, new characteristics of scientific revolutions are identified, the paradox is solved and evidence of a Zeroth Scientific Revolution emerges from the historical record.

Digital Revolution and Innovative Business Models in Healthcare: Global Trends and Russian Realities.

PubMed

Bereznoy, A V; Saygitov, R T

Digital revolution is one of the major global trends resulting in the unprecedented scale and depth of penetration of information and communication technologies into all sectors of national economy, including healthcare. The development of this trend brought about high expectations related to the improvement of quality of medical assistance, accessibility and economic efficiency of healthcare services. However, euphoria of the first steps of digital revolution is passing now, opening doors to more realistic analysis of opportunities and conditions of realization of the true potential hidden in the digital transformation of healthcare. More balanced perception of the peculiarities of innovation processes in the sector is coming together with understanding of the serious barriers, hampering implementation of the new ideas and practices due to complicated interweaving of social, economic, ethical and psychological factors. When taking into account the industry specifics it becomes evident that digital revolution cannot be a quick turnaround but rather would pass a number of phases and is likely to last more than one decade. In this context the article focuses on the prospects of the new business models, capable of making significant changes in today’s economic landscape of the sector (including uber-medicine, retail clinics, retainer medicine, network models of medical services). The authors also provide assessment of the current situation and perspectives of digital healthcare development in Russia.

The New High Ground: An Analysis of Space-Based Systems in the Information Revolution'

NASA Astrophysics Data System (ADS)

Mitchell, Olivia S.

2002-09-01

The Revolution in Military Affairs (RMA) was developed in 1989 by Andrew Marshall of the Office of Net Assessment in Washington. Based on Marshal Nikolai Ogarkov's doctrine of the Military-Technical Revolution, the RMA is defined as: A major change in the nature of warfare brought about by the innovative application of new technologies which, combined with dramatic changes in military doctrine, operations, and organizational concepts, fundamentally alters the character and conduct of military operations. Though no official definition exists, these requirements of technological innovation, new doctrine and operations concepts, and organizational change were used in the analysis of the 1991 Gulf War, resulting in the conclusion of the existence of a new RMA. Known as the Information Revolution, this RMA is centered on stealth technology, precision munitions, advanced sensors and increased communications, command, control, computer and intelligence (C4I). From these advancements, doctrinal development has taken place in both joint and service centered documents. These new doctrines have introduced the operational concepts of dominant maneuver, precision engagement, focused logistics and full-dimensional protection, culminating in the new core competency of full-spectrum dominance. Organizational changes to allow for the achievement of these new concepts consists of an increased focus on inter-service connectivity for joint operations and the mutation of the traditional military hierarchy into smaller, more mobile forces deployable for rapid reactions and tailored to the specific threat.

A Numerical Method for Calculating the Wave Drag of a Configuration from the Second Derivative of the Area Distribution of a Series of Equivalent Bodies of Revolution

NASA Technical Reports Server (NTRS)

Levy, Lionel L., Jr.; Yoshikawa, Kenneth K.

1959-01-01

A method based on linearized and slender-body theories, which is easily adapted to electronic-machine computing equipment, is developed for calculating the zero-lift wave drag of single- and multiple-component configurations from a knowledge of the second derivative of the area distribution of a series of equivalent bodies of revolution. The accuracy and computational time required of the method to calculate zero-lift wave drag is evaluated relative to another numerical method which employs the Tchebichef form of harmonic analysis of the area distribution of a series of equivalent bodies of revolution. The results of the evaluation indicate that the total zero-lift wave drag of a multiple-component configuration can generally be calculated most accurately as the sum of the zero-lift wave drag of each component alone plus the zero-lift interference wave drag between all pairs of components. The accuracy and computational time required of both methods to calculate total zero-lift wave drag at supersonic Mach numbers is comparable for airplane-type configurations. For systems of bodies of revolution both methods yield similar results with comparable accuracy; however, the present method only requires up to 60 percent of the computing time required of the harmonic-analysis method for two bodies of revolution and less time for a larger number of bodies.

The TXESS Revolution: A Partnership to Advance Earth and Space Science in Texas

NASA Astrophysics Data System (ADS)

Ellins, K. K.; Olson, H. C.; Willis, M.

2007-12-01

The Texas State Board of Education voted in 2006 to require a fourth year of science for graduation from high school and to authorize the creation of a new senior level Earth Systems and Space Science course as an option to fulfill that requirement. The new Earth Systems and Space Science course will be a capstone course for which three required science courses(biology, chemistry and physics)are prerequisites. Here, we summarize the collective efforts of business leaders, scientists and educators who worked collaboratively for almost a decade to successfully reinstate Earth science as part of Texas' standard high school curriculum and describe a new project, the Texas Earth and Space Science (TXESS) Revolution, a 5-year professional development program for 8th -12th grade minority and minority-serving science teachers and teacher mentors in Texas to help prepare them to teach the new capstone course. At the heart of TXESS Revolution is an extraordinary partnership, involving (1) two UT-Austin academic units, the Jackson School of Geosciences and the Department of Petroleum and Geosystems Engineering; (2) TERC, a not-for-profit educational enterprise in Massachusetts with 30 years experience in designing science curriculum; (3) the University of South Florida; and (4) the Texas Regional Collaboratives for Excellence in Science and Mathematics Teaching, a statewide network of teacher mentors and science teachers. With guidance from the Texas Education Agency, the state agency charged with overseeing education, the TXESS Revolution project will provide teachers with access to high quality materials and instruction aligned with the Texas educational standards for the new capstone course through: a program of eight different 3-day professional development academies offered to both teachers and teachers mentors; immersive summer institutes, field experiences, and a Petroleum Science and Technology Institute; training on how to implement Earth Science by Design, a teacher professional development program developed by TERC and the American Geological Institute with National Science Foundation (NSF) funding; and an online learning forum designed to keep teachers and teacher mentors in contact with facilitators and fellow project-participants between and after training, as well as share best practices and new information. The new capstone course promises to be a rigorous and dynamic change to the way Earth and Space Science has been presented previously anywhere in the U.S. and will provide many opportunities for professional development and the dissemination of suitable Earth and Space Science curriculum. The TXESS Revolution project welcomes opportunities to collaborate with geoscience consortia, programs, organizations and geoscience educators to advance Earth and Space Science in Texas. NSF's Opportunities to Enhance Diversity in the Geosciences program, the Shell Oil Company and the Jackson School of Geosciences are together funding the TXESS Revolution project.

Revolutions in energy input and material cycling in Earth history and human history

NASA Astrophysics Data System (ADS)

Lenton, Timothy M.; Pichler, Peter-Paul; Weisz, Helga

2016-04-01

Major revolutions in energy capture have occurred in both Earth and human history, with each transition resulting in higher energy input, altered material cycles and major consequences for the internal organization of the respective systems. In Earth history, we identify the origin of anoxygenic photosynthesis, the origin of oxygenic photosynthesis, and land colonization by eukaryotic photosynthesizers as step changes in free energy input to the biosphere. In human history we focus on the Palaeolithic use of fire, the Neolithic revolution to farming, and the Industrial revolution as step changes in free energy input to human societies. In each case we try to quantify the resulting increase in energy input, and discuss the consequences for material cycling and for biological and social organization. For most of human history, energy use by humans was but a tiny fraction of the overall energy input to the biosphere, as would be expected for any heterotrophic species. However, the industrial revolution gave humans the capacity to push energy inputs towards planetary scales and by the end of the 20th century human energy use had reached a magnitude comparable to the biosphere. By distinguishing world regions and income brackets we show the unequal distribution in energy and material use among contemporary humans. Looking ahead, a prospective sustainability revolution will require scaling up new renewable and decarbonized energy technologies and the development of much more efficient material recycling systems - thus creating a more autotrophic social metabolism. Such a transition must also anticipate a level of social organization that can implement the changes in energy input and material cycling without losing the large achievements in standard of living and individual liberation associated with industrial societies.

A second-order shock-expansion method applicable to bodies of revolution near zero lift

NASA Technical Reports Server (NTRS)

1957-01-01

A second-order shock-expansion method applicable to bodies of revolution is developed by the use of the predictions of the generalized shock-expansion method in combination with characteristics theory. Equations defining the zero-lift pressure distributions and the normal-force and pitching-moment derivatives are derived. Comparisons with experimental results show that the method is applicable at values of the similarity parameter, the ratio of free-stream Mach number to nose fineness ratio, from about 0.4 to 2.

Comprehensive force, moment, and pressure distribution measurements as well as flow visualization experiments were carried out to determine the influence of the Reynolds number on nonlinear normal forces of slender bodies of revolution. Experiments were performed in transonic wind tunnels at angles of attack up to 90 deg in the Mach number range 0.5 to 2.2 at variable Reynolds numbers. The results were analysed theoretically and an empirical theory was developed which describes the test results satisfactory.

From the water wheel to turbines and hydroelectricity. Technological evolution and revolutions

NASA Astrophysics Data System (ADS)

Viollet, Pierre-Louis

2017-08-01

Since its appearance in the first century BC, the water wheel has developed with increasing pre-industrial activities, and has been at the origin of the industrial revolution for metallurgy, textile mills, and paper mills. Since the nineteenth century, the water wheel has become highly efficient. The reaction turbine appeared by 1825, and continued to undergo technological development. The impulsion turbine appeared for high chutes, by 1880. Other turbines for low-head chutes were further designed. Turbine development was associated, after 1890, with the use of hydropower to generate electricity, both for industrial activities, and for the benefits of cities. A model ;one city + one plant; was followed in the twentieth century by more complex and efficient schemes when electrical interconnection developed, together with pumped plants for energy storage.

G-protein-coupled receptor structures were not built in a day.

Blois, Tracy M; Bowie, James U

2009-07-01

Among the most exciting recent developments in structural biology is the structure determination of G-protein-coupled receptors (GPCRs), which comprise the largest class of membrane proteins in mammalian cells and have enormous importance for disease and drug development. The GPCR structures are perhaps the most visible examples of a nascent revolution in membrane protein structure determination. Like other major milestones in science, however, such as the sequencing of the human genome, these achievements were built on a hidden foundation of technological developments. Here, we describe some of the methods that are fueling the membrane protein structure revolution and have enabled the determination of the current GPCR structures, along with new techniques that may lead to future structures.

The relativity revolution from the perspective of historical epistemology.

PubMed

Renn, Jürgen

2004-12-01

This essay analyzes Einstein's relativity revolution as part of a long-term development of knowledge in which the knowledge system of classical physics was reorganized in a process of reflection, described here as a "Copernican process." This process led in 1905 to the introduction of fundamentally new concepts of space, time, matter, and radiation. On the basis of an extensive historical reconstruction, the heuristics of Einstein's creation of the general theory of relativity, completing the relativity revolution, is interpreted as a further transformation of the knowledge of classical physics, starting from conceiving gravitation as a borderline problem between field theory and mechanics. The essay thus provides an answer to the puzzle of how Einstein was able to create a theory capable of accounting for a wide range of phenomena that were discovered only much later.

Development of a revolute-joint robot for the precision positioning of an x-ray detector

NASA Astrophysics Data System (ADS)

Preissner, Curt A.; Royston, Thomas J.; Shu, Deming

2003-10-01

This paper profiles the initial phase in the development of a six degree-of-freedom robot, with 1 μm dynamic positioning uncertainty, for the manipulation of x-ray detectors or test specimens at the Advanced Photon Source (APS). While revolute-joint robot manipulators exhibit a smaller footprint along with increased positioning flexibility compared to Cartesian manipulators, commercially available revolute-joint manipulators do not meet our size, positioning, or environmental specifications. Currently, a robot with 20 μm dynamic positioning uncertainty is functioning at the APS for cryogenic crystallography sample pick-and-place operation. Theoretical, computational and experimental procedures are being used to (1) identify and (2) simulate the dynamics of the present robot system using a multibody approach, including the mechanics and control architecture, and eventually to (3) design an improved version with a 1 μm dynamic positioning uncertainty. We expect that the preceding experimental and theoretical techniques will be useful design and analysis tools as multi-degree-of-freedom manipulators become more prevalent on synchrotron beamlines.

Manufacturing in the Eye of the Storm:Shen Hong and the Nine Great Installations Project During China's Cultural Revolution.

PubMed

Sun, Lie; Hu, Danian

2017-09-01

The construction of nine high-end technical installations (hereafter Project NGI, for Nine Great Installations or ) in the 1960s and 1970s was an indispensable part of the development of China's defense and heavy industries. The project put more than 1400 machines into operation or trial operation during the Culture Revolution (1966-1976), and they served essential technical functions in sectors such as aviation, aerospace, machinery, metallurgy, and electronics, and directly advancing the development of these fields. It took more than a decade for Project NGI to go from planning to completion-a surprisingly uninterrupted and steady development while China fell into unprecedented turmoil. One important reason for Project NGI's success was the vital leadership of Shen Hong (, 1906-1998), the technical director of the project and a high-ranking official. Supported by state leaders such as Zhou Enlai and Nie Rongzhen, Shen and his colleagues adopted a suitable roadmap for technological development, coordinated the best-performing manufacturing forces in the country, and successfully manufactured the NGI machines. Project NGI is significant for the history of Chinese science, technology, and medicine during the Cultural Revolution not because it was technologically original, but because it represents an extraordinary case, in which the project's technological development seemed to be largely exempted from the interference of the turbulent Cultural Revolution. The project's national defense orientation, its pragmatism, and the contemporary dogma of self-reliance (), in addition to Shen Hong's political maneuvering, all contributed to the creation of a relatively calm and favorable environment around Project NGI. Despite the widespread turmoil in the country, Shen managed to assemble a stable and continuously productive team, which executed experiments, absorbed previously introduced Soviet technologies, stayed informed about advanced European and American technologies, and ultimately accomplished the construction of the NGI machines.

TXESS Revolution: Utilizing TERC's EarthLabs Cryosphere Module to Support Professional Development of Texas Teachers

2010-12-01

TERC’s EarthLabs project provides rigorous and engaging Earth and environmental science labs. Four existing modules illustrate sequences for learning science concepts through data analysis activities and hands-on experiments. A fifth module, developed with NSF, comprises a series of linked inquiry based activities focused on the cryosphere to help students understand concepts around change over time on multiple and embedded time scales. Teachers recruited from the NSF-OEDG-sponsored Texas Earth and Space Science (TXESS) Revolution teacher professional development program conducted a pedagogical review of the Cryosphere EarthLabs module and provided feedback on how well the materials matched high school needs in Texas and were aligned with state and national standards. Five TXESS Revolution teachers field tested the materials in their classrooms and then trained other TXESS Revolution teachers on their implementation during spring and summer 2010. Here we report on the results of PD delivery during the summer 2010 TXESS Revolution summer institute as determined by (1) a set of evaluation instruments that included a pre-post concept map activity to assess changes in workshop teachers’ understanding of the concepts presented, a pre-post test content knowledge test, and a pre-post survey of teachers’ comfort in teaching the Texas Earth and Space Science standards addressed by the module; (2) teacher reflections; and (3) focus group responses. The findings reveal that the teachers liked the module activities and felt they could use them to teach Environmental and Earth Science. They appreciated that the sequence of activities contributed to a deeper understanding and observed that the variety of methods used to present the information accommodates different learning styles. Information about the cryosphere was new to all the teachers. The content knowledge tests reveal that although teachers made appreciable gains, their understanding of cryosphere, how it changes over time, and it’s role in Earth’s climate system remains weak. Our results clearly reflect the challenges of addressing the complexity of climate science and critical need for climate literacy education.

Chemistry as the defining science: discipline and training in nineteenth-century chemical laboratories.

PubMed

Jackson, Catherine M

2011-06-01

The institutional revolution has become a major landmark of late-nineteenth century science, marking the rapid construction of large, institutional laboratories which transformed scientific training and practice. Although it has served historians of physics well, the institutional revolution has proved much more contentious in the case of chemistry. I use published sources, mainly written by chemists and largely focused on laboratories built in German-speaking lands between about 1865 and 1900, to show that chemical laboratory design was inextricably linked to productive practice, large-scale pedagogy and disciplinary management. I argue that effective management of the novel risks inherent in teaching and doing organic synthesis was significant in driving and shaping the construction of late-nineteenth century institutional chemical laboratories, and that these laboratories were essential to the disciplinary development of chemistry. Seen in this way, the laboratory necessarily becomes part of the material culture of late-nineteenth century chemistry, and I show how this view leads not only to a revision of what is usually known as the laboratory revolution in chemistry but also to a new interpretation of the institutional revolution in physics.

Underwhelmed: hyperbole, regulatory policy, and the genetic revolution.

PubMed

Caulfield, T

2000-05-01

Rapid advances in the field of genetics in recent years have caused some commentators to suggest the emergence of a "genetic revolution." Such advances have been both praised as the "future of medicine" and condemned for encouraging the acceptance in society of laissez-faire eugenics. Yet the effect of technological advances flowing from the science of genetics appear somewhat overstated as few products of the genetic revolution, particularly in the areas of gene therapy and genetic testing, have managed to satisfy scientists' expectations to date. Furthermore, misdirected regulation of such advances can exacerbate the social, legal, and ethical problems associated with genetics, particularly in the context of health care, where issues of human cloning and the use of premature genetic testing technologies dominate current public debate. In this article, the author criticizes the hyperbolic rhetoric surrounding the genetic revolution and calls for a more balanced and informed approach to the development of genetic policies and regulations. Such an approach should include substantial interdisciplinary debate and an active role on the part of government in the identification and communication of accurate information relating to the effects of recent technological advances in the field of genetics.

The structure of the cognitive revolution: An examination from the philosophy of science

PubMed Central

O'Donohue, William; Ferguson, Kyle E.; Naugle, Amy E.

2003-01-01

The received view is that psychology has undergone several scientific revolutions similar to those that occurred in the physical sciences. Of these, this paper will consider the cognitive revolution. Because the arguments in favor of the existence of a cognitive revolution are cast using the concepts and terms of revolutionary science, we will examine the cognitive revolution using accounts of revolutionary science advanced by five influential philosophers of science. Specifically, we will draw from the philosophical positions of Popper, Kuhn, Lakatos, Laudan, and Gross for the purpose of discussion. We conclude that no substantive revolution took place according to these accounts. This conclusion is based on data gathered from some of the major participants in the “cognitive revolution” and on a general scholarly survey of the literature. We argue that the so-called cognitive revolution is best characterized as a socio-rhetorical phenomenon. PMID:22478396

Bioresorbable scaffolds: talking about a new interventional revolution [corrected].

2013-04-01

After the introduction of coronary balloon angioplasty, bare-metal, and drug-eluting stents, fully bioresorbable scaffolds (BRS) could be the fourth revolution in interventional cardiology. The BRS technology shares the advantages of metallic stents regarding acute gain and prevention of acute vessel occlusion by providing transient scaffolding, while potentially overcoming many of the safety concerns of drug-eluting stents. Furthermore, without a permanent metallic cage, the vessel could remodel favourably and atherosclerotic plaques could regress in the long-term. This attracted increased interest and several BRS have been developed. In this review we will describe all BRS which are thus far clinically evaluated and provide an overview of ongoing clinical studies. Although the technology seems to be very promising, more studies including patients with more complex lesions are needed to evaluate whether the BRS can be used in daily clinical practice and if it is indeed becoming a new interventional revolution.

When politics froze fashion: the effect of the Cultural Revolution on naming in Beijing.

Obukhova, Elena; Zuckerman, Ezra W; Zhang, Jiayin

2014-09-01

The authors examine the popularity of boys' given names in Beijing before and after the onset of the Cultural Revolution to clarify how exogenous and endogenous factors interact to shape fashion. Whereas recent work in the sociology of culture emphasizes the importance of endogenous processes in explaining fashion, their analysis demonstrates two ways in which politics shaped cultural expression during the Cultural Revolution: by promoting forms of expression reflecting prevailing political ideology and by limiting individuals' willingness to act differently. As argued by Lieberson and developed further in this article, the second condition is important because endogenous fashion cycles require a critical mass of individuals who seek to differentiate themselves from common practice. Exogenous factors can influence the operation of the endogenous factors. The authors discuss the implications of their study for understanding the nature of conformity under authoritarian regimes and social conditions supporting individual expression.

Impact of non-integer planetary revolutions on the distribution of evaporated optical coatings

DOE PAGES

Oliver, J. B.

2017-02-08

Planetary substrate rotation for optical-coating deposition is evaluated based on initial and final positions for a given layer with different numbers of revolutions and various deposition-source locations. The influence of partial revolutions of the rotation system is analyzed relative to the total number of planetary revolutions in that layer to determine the relative impact on film thickness and uniformity. Furthermore, guidance is provided on the necessary planetary revolutions that should take place in each layer versus the expected error level in the layer thickness for the modeled system.

Allen, H Julian; Perkins, Edward W

1951-01-01

The observed flow field about slender inclined bodies of revolution is compared with the calculated characteristics based upon potential theory. The comparison is instructive in indicating the manner in which the effects of viscosity are manifest. Based on this and other studies, a method is developed to allow for viscous effects on the force and moment characteristics of bodies. The calculated force and moment characteristics of two bodies of high fineness ratio are shown to be in good agreement, for most engineering purposes, with experiment. (author)

Generation of a crowned pinion tooth surface by a surface of revolution

NASA Technical Reports Server (NTRS)

Litvin, F. L.; Zhang, J.; Handschuh, R. F.

1988-01-01

A method of generating crowned pinion tooth surfaces using a surface of revolution is developed. The crowned pinion meshes with a regular involute gear and has a prescribed parabolic type of transmission errors when the gears operate in the aligned mode. When the gears are misaligned the transmission error remains parabolic with the maximum level still remaining very small (less than 0.34 arc sec for the numerical examples). Tooth contact analysis (TCA) is used to simulate the conditions of meshing, determine the transmission error, and determine the bearing contact.

[Development of new type plastics air turbine handpiece for dental use].

PubMed

Kusano, M

1989-06-01

The noise generated by the metal air turbine handpiece employed in dental practice is considerable and attended with predominant high frequency components. Therefore, investigation of the noise generation mechanism and development of a silent air turbine handpiece was only a matter of course. In addition, the metal air turbine hardpiece is comparatively heavy and its production cost is high. From this point of view as well, production of a light air turbine handpiece at low cost is also desirable. In order to overcome the objections to the metal air turbine handpiece, appropriate plastics materials were employed wherever possible. In this study, the number of revolutions, noise level, frequency analysis, start pressure and weight of newly produced plastics handpieces and metal handpieces were examined and compared. The following results were obtained: 1. The number of revolutions of single-nozzle type air turbine handpieces encased in plastics housings and fitted with metal turbine rotors was higher than that of all-metal air turbine handpieces. The noise level of the former tended to be lower. 2. The number of revolutions of multi-nozzle type air turbine handpieces encased in plastics housings and fitted with turbine rotors with plastics turbine blades was almost equal to that of similar metal handpieces, with the noise level tending to be lower. 3. In the case of handpieces fitted with turbine rotors with dynamic balance, the number of revolutions was high and the noise level was low. This indicated that dynamic balance was a factor affecting the number of revolutions and noise level. 4. Narrow band sound frequency analysis of single-nozzle type air turbine handpieces showed a sharp peak at the fundamental frequency which was the same as the number of revolutions multiplied by the number of rotor turbine blades. It is thought that the noise from air turbine handpieces was aerodynamic in origin, being generated by the periodical interruption of steady air flow by rotor turbine blades. 5. The start pressure of plastics handpieces was almost equal to that of metal handpieces. 6. The weight of plastics handpieces was 20%-50% of that of metal handpieces. The present results indicate that it is possible to produce a new type of light, silent and aesthetical air turbine handpiece.

Rotor Wake Development During the First Revolution

NASA Technical Reports Server (NTRS)

McAlister, Kenneth W.

2003-01-01

The wake behind a two-bladed model rotor in light climb was measured using particle image velocimetry, with particular emphasis on the development of the trailing vortex during the first revolution of the rotor. The distribution of vorticity was distinguished from the slightly elliptical swirl pattern. Peculiar dynamics within the void region may explain why the peak vorticity appeared to shift away from the center as the vortex aged, suggesting the onset of instability. The swirl and axial velocities (which reached 44 and 12 percent of the rotor-tip speed, respectively) were found to be asymmetric relative to the vortex center. In particular, the axial flow was composed of two concentrated zones moving in opposite directions. The radial distribution of the circulation rapidly increased in magnitude until reaching a point just beyond the core radius, after which the rate of growth decreased significantly. The core-radius circulation increased slightly with wake age, but the large-radius circulation appeared to remain relatively constant. The radial distributions of swirl velocity and vorticity exhibit self-similar behaviors, especially within the core. The diameter of the vortex core was initially about 10 percent of the rotor-blade chord, but more than doubled its size after one revolution of the rotor. According to vortex models that approximate the measured data, the core-radius circulation was about 79 percent of the large-radius circulation, and the large-radius circulation was about 67 percent of the maximum bound circulation on the rotor blade. On average, about 53 percent of the maximum bound circulation resides within the vortex core during the first revolution of the rotor.

Olesen, C G; Larsen, B H; Andresen, E L; de Zee, M

2015-01-01

The aim of this study was to develop a performance test set-up for America's Cup grinders. The test set-up had to mimic the on-boat grinding activity and be capable of collecting data for analysis and evaluation of grinding performance. This study included a literature-based analysis of grinding demands and a test protocol developed to accommodate the necessary physiological loads. This study resulted in a test protocol consisting of 10 intervals of 20 revolutions each interspersed with active resting periods of 50 s. The 20 revolutions are a combination of both forward and backward grinding and an exponentially rising resistance. A custom-made grinding ergometer was developed with computer-controlled resistance and capable of collecting data during the test. The data collected can be used to find measures of grinding performance such as peak power, time to complete and the decline in repeated grinding performance.

The Darwinian revolution: Rethinking its meaning and significance

PubMed Central

Ruse, Michael

2009-01-01

The Darwinian revolution is generally taken to be one of the key events in the history of Western science. In recent years, however, the very notion of a scientific revolution has come under attack, and in the specific case of Charles Darwin and his Origin of Species there are serious questions about the nature of the change (if there was such) and the specifically Darwinian input. This article considers these issues by addressing these questions: Was there a Darwinian revolution? That is, was there a revolution at all? Was there a Darwinian revolution? That is, what was the specific contribution of Charles Darwin? Was there a Darwinian revolution? That is, what was the conceptual nature of what occurred on and around the publication of the Origin? I argue that there was a major change, both scientifically and in a broader metaphysical sense; that Charles Darwin was the major player in the change, although one must qualify the nature and the extent of the change, looking particularly at things in a broader historical context than just as an immediate event; and that the revolution was complex and we need the insights of rather different philosophies of scientific change to capture the whole phenomenon. In some respects, indeed, the process of analysis is still ongoing and unresolved. PMID:19528652

An improved, robust, axial line singularity method for bodies of revolution

The failures encountered in attempts to increase the range of applicability of the axial line singularity method for representing incompressible, inviscid flow about an inclined and slender body-of-revolution are presently noted to be common to all efforts to solve Fredholm equations of the first kind. It is shown that a previously developed smoothing technique yields a robust method for numerical solution of the governing equations; this technique is easily retrofitted to existing codes, and allows the number of circularities to be increased until the most accurate line singularity solution is obtained.

Tapping the RNA world for therapeutics.

2018-05-01

A recent revolution in RNA biology has led to the identification of new RNA classes with unanticipated functions, new types of RNA modifications, an unexpected multiplicity of alternative transcripts and widespread transcription of extragenic regions. This development in basic RNA biology has spawned a corresponding revolution in RNA-based strategies to generate new types of therapeutics. Here, I review RNA-based drug design and discuss barriers to broader applications and possible ways to overcome them. Because they target nucleic acids rather than proteins, RNA-based drugs promise to greatly extend the domain of 'druggable' targets beyond what can be achieved with small molecules and biologics.

Providing Elementary Teachers in South Texas with Professional Development to Improve Earth Science Instruction

NASA Astrophysics Data System (ADS)

Borrego, H.; Ellins, K. K.

2011-12-01

Through three years of participation in the TeXas Earth and Space Science (TXESS) Revolution, an NSF-sponsored teacher professional development program, my knowledge of earth science, new pedagogical approaches, and confidence has improved dramatically. I have also received instructional materials and learned how to access high quality online resources and use a variety of web-based tools. In this session, I will share my experiences and report on how I used my own learning to help both teachers and students to become more earth science literate individuals. Earth Science test scores at the elementary level throughout South Texas are consistently low in comparison to other regions in the state. The majority of the teachers lack the content-knowledge, confidence, or experience to teach Earth Sciences. My TXESS Revolution experience helped me to understand the needs of these teachers and to identify teaching resources that would be useful to them. Particularly noteworthy are TERC's EarthLabs: Earth System Science and GLOBE activities. Although these Earthlab investigations are designed for high schools students, I demonstrated how they could be adapted for elementary students. As a result, I have provided professional development in the Earth Sciences to about 300 South Texas elementary teachers. TXESS Revolution has also equipped me to empower the students I teach. My students this past year presented their challenge Legacy Cycle Project to the community. The TXESS Revolution teamed up with the Texas Water Development Board to deliver training on the implementation of a new online challenged-based curriculum called the Water Exploration Legacy Cycles. This training gave me the tools to guide my students learning through authentic scientific research. To carry out their challenge, students researched an area of interest, read literature, consulted with experts in the field, consider different prospective, and presented their final products via PowerPoint, poster, public announcement, and pamphlet to the community. From great farming soil for organic gardens, to healthy recipes for diabetes and obesity health problems, our community benefited from the authentic scientific research these students presented. The results and knowledge gain by these 5th grade students at Quest Academy was impressive and top-rated by the community. In addition to providing professional development to teachers, I was asked to write the 5th grade science curriculum for IDEA Public School. I used my training in Earth Science by Design, offered by TXESS Revolution in partnership with TERC to accomplish the task. Teachers at Quest Academy followed this framework closely. I believe it is partially responsible for our district receiving an Exemplary rating by Texas Education Agency for two consecutive years. Only one more districts in South Texas was awarded the Exemplary rating. As a result of being part of TXESS Revolution, I am more confident in my teaching practice and I have been recently offered a part-time lecturer job at UT-Pan American teaching an undergraduate course in science for elementary teachers. I have made a commitment to continue to empower both teachers I train and students I teach.

The Development of Genetics in the Light of Thomas Kuhn's Theory of Scientific Revolutions.

PubMed

Portin, Petter

2015-01-01

The concept of a paradigm is in the key position in Thomas Kuhn's theory of scientific revolutions. A paradigm is the framework within which the results, concepts, hypotheses and theories of scientific research work are understood. According to Kuhn, a paradigm guides the working and efforts of scientists during the time period which he calls the period of normal science. Before long, however, normal science leads to unexplained matters, a situation that then leads the development of the scientific discipline in question to a paradigm shift--a scientific revolution. When a new theory is born, it has either gradually emerged as an extension of the past theory, or the old theory has become a borderline case in the new theory. In the former case, one can speak of a paradigm extension. According to the present author, the development of modern genetics has, until very recent years, been guided by a single paradigm, the Mendelian paradigm which Gregor Mendel launched 150 years ago, and under the guidance of this paradigm the development of genetics has proceeded in a normal fashion in the spirit of logical positivism. Modern discoveries in genetics have, however, created a situation which seems to be leading toward a paradigm shift. The most significant of these discoveries are the findings of adaptive mutations, the phenomenon of transgenerational epigenetic inheritance, and, above all, the present deeply critical state of the concept of the gene.

Low-Thrust Many-Revolution Trajectory Optimization via Differential Dynamic Programming and a Sundman Transformation

2018-01-01

Low-thrust trajectories about planetary bodies characteristically span a high count of orbital revolutions. Directing the thrust vector over many revolutions presents a challenging optimization problem for any conventional strategy. This paper demonstrates the tractability of low-thrust trajectory optimization about planetary bodies by applying a Sundman transformation to change the independent variable of the spacecraft equations of motion to an orbit angle and performing the optimization with differential dynamic programming. Fuel-optimal geocentric transfers are computed with the transfer duration extended up to 2000 revolutions. The flexibility of the approach to higher fidelity dynamics is shown with Earth's J 2 perturbation and lunar gravity included for a 500 revolution transfer.

Existing theory has identified the capacity of political revolutions to effect change in a variety of social institutions, although relationships between revolution and many institutions remain unexplored. Using historical data from 22 European and four diaspora countries, I examine the temporal relationship between timing of revolution and onset of fertility decline. I hypothesize that specific kinds of revolutionary events affect fertility by engendering ideological changes in popular understandings of the individual’s relationship to society, and ultimately the legitimacy of couples’ authority over their reproductive capacities. Results demonstrate that popular democratic revolution – but not institutionalized democratic structures – predict the timing of the onset of fertility decline. PMID:19999826

Woodrum, Randall Brock

This thesis presents the work performed on lathing PBX 9501 to gather and analyze cutting force and temperature data during the machining process. This data will be used to decrease federal-regulation-constrained machining time of the high explosive PBX 9501. The effects of machining parameters depth of cut, surface feet per minute, and inches per revolution on cutting force and cutting interface were evaluated. Cutting tools of tip radius 0.005 -inches and 0.05 -inches were tested to determine what effect the tool shape had on the machining process as well. A consistently repeatable relationship of temperature to changing depth of cutmore » and surface feet per minute is found, while only a weak dependence was found to changing inches per revolution. Results also show the relation of cutting force to depth of cut and inches per revolution, while weak dependence on SFM is found. Conclusions suggest rapid, shallow cuts optimize machining time for a billet of PBX 9501, while minimizing temperature increase and cutting force.« less

A comparison of the experimental subsonic pressure distributions about several bodies of revolution with pressure distributions computed by means of the linearized theory

NASA Technical Reports Server (NTRS)

Matthews, Clarence W

1953-01-01

An analysis is made of the effects of compressibility on the pressure coefficients about several bodies of revolution by comparing experimentally determined pressure coefficients with corresponding pressure coefficients calculated by the use of the linearized equations of compressible flow. The results show that the theoretical methods predict the subsonic pressure-coefficient changes over the central part of the body but do not predict the pressure-coefficient changes near the nose. Extrapolation of the linearized subsonic theory into the mixed subsonic-supersonic flow region fails to predict a rearward movement of the negative pressure-coefficient peak which occurs after the critical stream Mach number has been attained. Two equations developed from a consideration of the subsonic compressible flow about a prolate spheroid are shown to predict, approximately, the change with Mach number of the subsonic pressure coefficients for regular bodies of revolution of fineness ratio 6 or greater.

[Trueness of modern natural science (1): the scientific revolution and the problem of philosophy].

PubMed

Maeda, Y

2001-12-01

How can one characterize modern Europe? This problem is essentially related to the meaning of modern natural science, which was developed during the scientific revolution. Then how did viewpoints change during this revolution? The answer to this question also determined the basic character of modern philosophy. Through the examination of Aristotle's geocentric theory and kinematics, I have come to believe that the defect of Aristotle's was that he concluded that a visible sense image is an actual reflection of the reality as it is. From this point of view, the traditional theory of truth called "correspondence theory" is found to be an insufficient one. Therefore, in this paper I will show that the methodological and philosophical question "How do we see reality among phenomena?" is a very important one. This question is the one Plato struggled with, and also the one which guided Kant. It may be said that this can be seen as a group for a new metaphysics as a basic theory of reality.

The purpose of this essay is to share Kan Koffi's ideas about scientific revolutions in the discipline of nursing. Koffi has proposed that the works of Florence Nightingale and Martha E. Rogers represent two scientific revolutions in nursing as a learned discipline. The outcome of these two scientific revolutions is a catalyst for critical disciplinary and paradigmatic debate about the universal conceptualization of nursing's distinctive professional and scientific knowledge. © The Author(s) 2016.

Discovery of a new motion mechanism of biomotors similar to the earth revolving around the sun without rotation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Guo, Peixuan, E-mail: peixuan.guo@uky.edu; Schwartz, Chad; Haak, Jeannie

Biomotors have been classified into linear and rotational motors. For 35 years, it has been popularly believed that viral dsDNA-packaging apparatuses are pentameric rotation motors. Recently, a third class of hexameric motor has been found in bacteriophage phi29 that utilizes a mechanism of revolution without rotation, friction, coiling, or torque. This review addresses how packaging motors control dsDNA one-way traffic; how four electropositive layers in the channel interact with the electronegative phosphate backbone to generate four steps in translocating one dsDNA helix; how motors resolve the mismatch between 10.5 bases and 12 connector subunits per cycle of revolution; and howmore » ATP regulates sequential action of motor ATPase. Since motors with all number of subunits can utilize the revolution mechanism, this finding helps resolve puzzles and debates concerning the oligomeric nature of packaging motors in many phage systems. This revolution mechanism helps to solve the undesirable dsDNA supercoiling issue involved in rotation. - Highlights: • New motion mechanism of revolution without rotation found for phi29 DNA packaging. • Revolution motor finding expands classical linear and rotation biomotor classes. • Revolution motors transport dsDNA unidirectionally without supercoiling. • New mechanism solves many puzzles, mysteries, and debates in biomotor studies. • Motors with all numbers of subunits can utilize the revolution mechanism.« less

Perturbations of a close-earth satellite due to sunlight diffusely reflected from the earth. I - Uniform albedo

NASA Technical Reports Server (NTRS)

Lautman, D. A.

1977-01-01

A semianalytic method has been developed to calculate the radiation-pressure perturbations of a close-earth satellite due to sunlight reflected from the earth. The assumptions made are that the satellite is spherically symmetric and that the solar radiation is reflected from the earth according to Lambert's Law with uniform albedo. By using expressions for the components of the radiation-pressure force due to Lochry, the expressions for the perturbations of the elements were developed into series in the true anomaly. The perturbations within a given revolution can be obtained analytically by integrating with respect to v while holding all slowly varying quantities constant. The long-range perturbations are then obtained by accumulating the net perturbations at the end of each revolution.

Information revolution in nursing and health care: educating for tomorrow's challenge.

Current emphasis on the national electronic highway and a national health database for comparative health care reporting demonstrates society's increasing reliance on information technology. The efficient electronic processing and managing of data, information, and knowledge are critical for survival in tomorrow's health care organization. To take a leadership role in this information revolution, informatics nurse specialists must possess competencies that incorporate information science, computer science, and nursing science for successful information system development. In selecting an appropriate informatics educational program or to hire an individual capable of meeting this challenge, nurse administrators must look for the following technical knowledge and skill set: information management principles, system development life cycle, programming languages, file design and access, hardware and network architecture, project management skills, and leadership abilities.

Witchcraft beliefs and witch hunts: an interdisciplinary explanation.

PubMed

Koning, Niek

2013-06-01

This paper proposes an interdisciplinary explanation of the cross-cultural similarities and evolutionary patterns of witchcraft beliefs. It argues that human social dilemmas have led to the evolution of a fear system that is sensitive to signs of deceit and envy. This was adapted in the evolutionary environment of small foraging bands but became overstimulated by the consequences of the Agricultural Revolution, leading to witch paranoia. State formation, civilization, and economic development abated the fear of witches and replaced it in part with more collectivist forms of social paranoia. However, demographic-economic crises could rekindle fear of witches-resulting, for example, in the witch craze of early modern Europe. The Industrial Revolution broke the Malthusian shackles, but modern economic growth requires agricultural development as a starting point. In sub-Saharan Africa, witch paranoia has resurged because the conditions for agricultural development are lacking, leading to fighting for opportunities and an erosion of intergenerational reciprocity.

We are living in an era characterized by an unprecedented scientific and technological revolution, which is also affecting both the health and medical fields. The revolution surrounding the cancer field is drastically changing not only the research and development sector, but also the manner in which malignancies are diagnosed and treated. This is due to achievements in genome, molecular immunology, and stem cell research. Here are some examples of molecular targeted therapy drugs. The targeted drug crizotinib, developed after the discovery of driver genes and genotype identification, opened up a newera of genome clinical sequencing. Mogamulizumab not only targets the chemokine receptor CCR4 but also modifies host antitumor immunity by suppressing Tregs. Trametinib is a molecular targeted therapy drug that controls molecules associated with the control system responsible for tumor maintenance. The creation of an assay system resulted in a breakthrough in this field, which led to the development of trametinib and crizotinib. The checkpoint inhibitor nivolumab acts on the immune system of the host and promotes tumor targeting. As exemplified by these developments, the paradigm of cancer drug therapy is changing from a probabilistic approach(ie, administering a general anticancer drug), to a deterministic approach(ie, administering the most adequate drug after diagnosing the specific mechanisms responsible for tumor generation, sustenance, and progression). The latter requires a drastic change in the way clinical trials are performed. Thus, we are now entering a newphase: the era of precision medicine. Herewe discuss the present state of the cancer medical revolution and the academic progress in research and development and cancer therapy in our country.

Finding of widespread viral and bacterial revolution dsDNA translocation motors distinct from rotation motors by channel chirality and size

PubMed Central

2014-01-01

Background Double-stranded DNA translocation is ubiquitous in living systems. Cell mitosis, bacterial binary fission, DNA replication or repair, homologous recombination, Holliday junction resolution, viral genome packaging and cell entry all involve biomotor-driven dsDNA translocation. Previously, biomotors have been primarily classified into linear and rotational motors. We recently discovered a third class of dsDNA translocation motors in Phi29 utilizing revolution mechanism without rotation. Analogically, the Earth rotates around its own axis every 24 hours, but revolves around the Sun every 365 days. Results Single-channel DNA translocation conductance assay combined with structure inspections of motor channels on bacteriophages P22, SPP1, HK97, T7, T4, Phi29, and other dsDNA translocation motors such as bacterial FtsK and eukaryotic mimiviruses or vaccinia viruses showed that revolution motor is widespread. The force generation mechanism for revolution motors is elucidated. Revolution motors can be differentiated from rotation motors by their channel size and chirality. Crystal structure inspection revealed that revolution motors commonly exhibit channel diameters larger than 3 nm, while rotation motors that rotate around one of the two separated DNA strands feature a diameter smaller than 2 nm. Phi29 revolution motor translocated double- and tetra-stranded DNA that occupied 32% and 64% of the narrowest channel cross-section, respectively, evidencing that revolution motors exhibit channel diameters significantly wider than the dsDNA. Left-handed oriented channels found in revolution motors drive the right-handed dsDNA via anti-chiral interaction, while right-handed channels observed in rotation motors drive the right-handed dsDNA via parallel threads. Tethering both the motor and the dsDNA distal-end of the revolution motor does not block DNA packaging, indicating that no rotation is required for motors of dsDNA phages, while a small-angle left-handed twist of dsDNA that is aligned with the channel could occur due to the conformational change of the phage motor channels from a left-handed configuration for DNA entry to a right-handed configuration for DNA ejection for host cell infection. Conclusions The revolution motor is widespread among biological systems, and can be distinguished from rotation motors by channel size and chirality. The revolution mechanism renders dsDNA void of coiling and torque during translocation of the lengthy helical chromosome, thus resulting in more efficient motor energy conversion. PMID:24940480

Crowned spur gears - Methods for generation and Tooth Contact Analysis. II - Generation of the pinion tooth surface by a surface of revolution

NASA Technical Reports Server (NTRS)

Litvin, F. L.; Handschuh, R. F.; Zhang, J.

1988-01-01

A method for generation of crowned pinion tooth surfaces using a surface of revolution is developed. The crowned pinion meshes with a regular involute gear and has a prescribed parabolic type of transmission errors when the gears operate in the aligned mode. When the gears are misaligned the transmission error remains parabolic with the maximum level still remaining very small (less than 0.34 arc second for the numerical examples). Tooth Contact Analysis (TCA) is used to simulate the conditions of meshing, determine the transmission error, and the bearing contact.

Boundary layer control for airships

NASA Technical Reports Server (NTRS)

Pake, F. A.; Pipitone, S. J.

1975-01-01

An investigation is summarized of the aerodynamic principle of boundary layer control for nonrigid LTA craft. The project included a wind tunnel test on a BLC body of revolution at zero angle of attack. Theoretical analysis is shown to be in excellent agreement with the test data. Methods are evolved for predicting the boundary layer development on a body of revolution and the suction pumping and propulsive power requirements. These methods are used to predict the performance characteristics of a full-scale airship. The analysis indicates that propulsive power reductions of 15 to 25 percent and endurance improvements of 20 to 40 percent may be realized in employing boundary-layer control to nonrigid airships.

Lessons learned in command environment development

Wallace, Daniel F.; Collie, Brad E.

2000-11-01

As we consider the issues associated with the development of an Integrated Command Environment (ICE), we must obviously consider the rich history in the development of control rooms, operations centers, information centers, dispatch offices, and other command and control environments. This paper considers the historical perspective of control environments from the industrial revolution through the information revolution, and examines the historical influences and the implications that that has for us today. Environments to be considered are military command and control spaces, emergency response centers, medical response centers, nuclear reactor control rooms, and operations centers. Historical 'lessons learned' from the development and evolution of these environments will be examined to determine valuable models to use, and those to be avoided. What are the pitfalls? What are the assumptions that drive the environment design? Three case histories will be presented, examining (1) the control room of the Three Mile Island power plant, (2) the redesign of the US Naval Space Command operations center, and (3) a testbed for an ICE aboard a naval surface combatant.

M. Brewster-Smith (1968) divided the history of psychiatry into three revolutionary periods. The first was the unshackling of the lunatics and the conception of mental illness. The second revolution was the spread of the dynamic theory of Freud with its emphasis on the one-to-one therapeutic relationship. The third revolution was the community mental health movement with its emphasis on bringing treatment into the community. We are now on the verge of yet another revolution. The new revolution is quiet and its leaders come from within the psychiatric profession. The major feature of this revolution is the binding together of medical authority and social treatment models within a corporate structure. The new movement takes the individually oriented private practitioners and shows them that in union there is profit.

Supermarket revolution in Asia and emerging development strategies to include small farmers

PubMed Central

Reardon, Thomas; Timmer, C. Peter; Minten, Bart

2012-01-01

A “supermarket revolution” has occurred in developing countries in the past 2 decades. We focus on three specific issues that reflect the impact of this revolution, particularly in Asia: continuity in transformation, innovation in transformation, and unique development strategies. First, the record shows that the rapid growth observed in the early 2000s in China, Indonesia, Malaysia, and Thailand has continued, and the “newcomers”—India and Vietnam—have grown even faster. Although foreign direct investment has been important, the roles of domestic conglomerates and even state investment have been significant and unique. Second, Asia's supermarket revolution has exhibited unique pathways of retail diffusion and procurement system change. There has been “precocious” penetration of rural towns by rural supermarkets and rural business hubs, emergence of penetration of fresh produce retail that took much longer to initiate in other regions, and emergence of Asian retail developing-country multinational chains. In procurement, a symbiosis between modern retail and the emerging and consolidating modern food processing and logistics sectors has arisen. Third, several approaches are being tried to link small farmers to supermarkets. Some are unique to Asia, for example assembling into a “hub” or “platform” or “park” the various companies and services that link farmers to modern markets. Other approaches relatively new to Asia are found elsewhere, especially in Latin America, including “bringing modern markets to farmers” by establishing collection centers and multipronged collection cum service provision arrangements, and forming market cooperatives and farmer companies to help small farmers access supermarkets.

Many American companies have found that saving energy and cutting pollution dramatically improves the bottom line. But beyond these gains, businesses that launch energy efficiency programs to save money are often astonished to discover unforeseen benefits: energy efficient lighting, heating, cooling, motors, and industrial processes can increase worker productivity, decrease absenteeism, and improve the quality of work performed. Profits created by the jump in worker productivity can exceed energy savings by a factor of ten.

Anthropometric history of the French Revolution in the Province of Orleans.

Schubert, Hermann

2011-07-01

We estimate the trend in average height of the population of the French province Orleans from 1715 to the beginning of the 19th century using data on recruits who were drafted either through a lottery system or through general conscription. After controlling for age, residence, and occupation, we find a general decline in the biological standard of living in the decades before the French Revolution. The results support a Ricardian-Malthusian interpretation of the causes of the French Revolution. In the debate 'Revolution de la misère ou de la prospérité' our findings support the side which argues that the French Revolution was a culmination of a long-lasting economic malaise during the final phases of the Ancien Régime.

Human exposure to selamectin from dogs treated with revolution: methodological consideration for selamectin isolation.

PubMed

Gupta, R C; Masthay, M B; Canerdy, T D; Acosta, T M; Provost, R J; Britton, D M; Atieh, B H; Keller, R J

2005-01-01

This study was undertaken to determine selamectin residue in dog's blood and in gloves worn while petting dogs after Revolution application. Revolution contains the active ingredient selamectin (a semisynthetic avermectin), which controls endoparasites and ectoparasites, including adult fleas, flea eggs, ticks, heartworms, ear mites, and sarcoptic mange in dogs, for 30 days. Revolution was applied topically on a group of six adult house hold dogs (240 mg selamectin/dog). The gloves worn for 5 min while petting the dogs were collected in glass jars and the blood samples (5 mL/dog) were collected in EDTA tubes at 0 h, 24 h, and 72 h, and at 1, 2, 3, 4, and 5 weeks post-Revolution application for selamectin residue determination. At no time during the study did the dogs show any signs of toxicity, weight loss, or change in body temperature. Extracts of the blood and the gloves were analyzed for selamectin residue using RP-HPLC coupled with a UV detector (246 nm). Selamectin standard used for peak identification and quantitation was purified from Revolution. Selamectin residue was detected in the blood (10.26 +/- 1.06 ng/mL) only at 72 h post-Revolution application, probably due to its poor dermal absorption and rapid elimination from the circulation. In the glove extracts, the highest concentration of selamectin (518.90 +/- 66.80 ppm) was detected 24 h after Revolution application. Transferable residue of selamectin in gloves from dog's coat was detected at a lesser magnitude after 1 week of Revolution application, and that was followed by a further descending trend during the second, third, and fourth weeks. No selamectin residue was detected in the glove extracts after the fifth week. In spite of selamectin's binding to the sebaceous glands of the skin, gloves contained significant transferable residue. Thus, these findings suggest that repeated exposure to selamectin can pose potential health risks, especially to veterinarians, veterinary technologists, dog trainers/handlers, and pet owners.

[Health and environment: the 2nd public health revolution.].

PubMed

Cicolella, André

2010-01-01

As of the mid-19th century, most infectious disease epidemics have been fought and slowed down by taking action on the environment (water, housing, waste) and education. This constitutes the 1st public health revolution paradigm. As we face the current epidemic of chronic diseases and the failure of the dominant biomedical model to stop them, a 2nd public health revolution is needed. The vision for this 2nd public health revolution requires a new paradigm built upon an eco-systemic definition of health and the recognition of the legitimacy for citizen participation based on the precautionary principle.

Low-Thrust Many-Revolution Trajectory Optimization via Differential Dynamic Programming and a Sundman Transformation

NASA Technical Reports Server (NTRS)

Aziz, Jonathan D.; Parker, Jeffrey S.; Scheeres, Daniel J.; Englander, Jacob A.

2017-01-01

Low-thrust trajectories about planetary bodies characteristically span a high count of orbital revolutions. Directing the thrust vector over many revolutions presents a challenging optimization problem for any conventional strategy. This paper demonstrates the tractability of low-thrust trajectory optimization about planetary bodies by applying a Sundman transformation to change the independent variable of the spacecraft equations of motion to the eccentric anomaly and performing the optimization with differential dynamic programming. Fuel-optimal geocentric transfers are shown in excess of 1000 revolutions while subject to Earths J2 perturbation and lunar gravity.

The New Era of Counterforce

NASA Astrophysics Data System (ADS)

Lieber, Keir

Nuclear deterrence rests on the survivability of nuclear arsenals. For much of the nuclear age, counterforce disarming attacks those aimed at eliminating nuclear forces were nearly impossible because of the ability of potential victims to hide and protect their weapons. However, technological developments are eroding this foundation of nuclear deterrence. Advances rooted in the computer revolution have made nuclear forces around the world far more vulnerable than before. Specifically, two key approaches that countries have relied on to ensure arsenal survivability since the dawn of the nuclear age hardening and concealment have been undercut by leaps in weapons accuracy and a revolution in remote sensing. Various models, methods, and evidence demonstrate the emergence of new possibilities for counterforce disarming strikes. In short, the task of securing nuclear arsenals against attack is a far greater challenge than it was in the past. The new era of counterforce challenges the basis for confidence in contemporary deterrence stability, raises critical issues for national and international security policy, and sheds light on one of the enduring theoretical puzzles of the nuclear era: why international security competition has endured in the shadow of the nuclear revolution.

The Empire strikes back. Counterrevolutionary strategies for industry leaders.

PubMed

D'Aveni, Richard

2002-11-01

Industry leaders frequently worry that their companies will fall victim to some revolutionary business model or disruptive technology. But new research shows that it's strategically better for incumbents to counter a revolution than to ignore or fully embrace it. Successful incumbents rely on one or more of five approaches to restrain, modify, or, if necessary, neutralize a revolutionary threat. A company that perceives a revolution in its earliest stages can use containment strategies. By throwing up roadblocks--raising switching costs, perhaps, or launching discrediting PR efforts--an incumbent can often limit the degree to which customers and competitors accept a nascent insurgency. And, sometimes, revolutions die there. If not, early containment buys a company some time to shape the revolution so that it complements, rather than supersedes, the incumbent's strengths. And even if shaping efforts fail, they can give an industry leader more time to work out how to absorb the threat by bringing the new competencies or technologies inside the firm in such a way that they don't destroy its existing strengths and capabilities. When revolutions have progressed too far to slow them down, incumbents must take a more aggressive tack. Neutralizing strategies meet a revolution head-on and terminate it--by, say, temporarily giving away the benefits offered by the challenger for free. Annulment strategies allow the market leader to leapfrog over or sidestep the threat. These five strategic approaches need not be used in isolation, as a detailed case study of the way Anheuser-Busch countered the craft-beer revolution dramatically demonstrates. Sensible industry leaders do not lead revolutions; they know they may not survive the attempt. Instead, they prefer to lead counterrevolutions.

Calculation of stability derivatives for slowly oscillating bodies of revolution at Mach 1.0

NASA Technical Reports Server (NTRS)

Ruo, S. Y.; Liu, D. D.

1971-01-01

A parabolic method for steady transonic flow is extended to bodies of revolution oscillating in a sonic flow field. A Laplace transform technique is employed to derive the dipole solution, and the Adams-Sears iterative technique is used in the stability derivative calculation. A computer program is developed to perform the stability derivative calculation for the slowly oscillating cone and parabolic ogive. Inputs for the program are body geometry thickness ratio, acceleration constant, and pitch axis location. Sample calculations were performed for the parabolic ogive and circular cone and results are compared with those obtained by using other techniques and the available experimental data for circular cones.

Lake, Mark S.; Warren, Peter A.; Peterson, Lee D.

1996-01-01

NASA Langley Research center is developing key structures and mechanisms technologies for micron-accuracy, in-space deployment of future space instruments. Achieving micron-accuracy deployment requires significant advancements in deployment mechanism design such as the revolute joint presented herein. The joint presented herein exhibits a load-cycling response that is essentially linear with less than two percent hysteresis, and the joint rotates with less than one in.-oz. of resistance. A prototype reflector metering truss incorporating the joint exhibits only a few microns of kinematic error under repeated deployment and impulse loading. No other mechanically deployable structure found in literature has been demonstrated to be this kinematically accurate.

Aplanatic Two-Surface Systems: The Optics Of Our Grandfathers

NASA Astrophysics Data System (ADS)

Krautter, Martin

1986-10-01

Karl Schwarzschild (1873 - 1916)1 has set up the 2-mirror systems as a 2-parameter mani-fold. He constructed them for primary aplanatism with conic section surfaces, and for finite aplanatism with numerically determined surfaces of revolution. Developing from the still older 2-paraboloid telescopes, conceived by Marin Mersenne, the systems since designed fill three domains of existence. The grazing incidence systems too (the Wolter-Schwarz-schild systems) have their loci on this map. Martin Linnemann (born 1880), student of Karl Schwarzschild, designed the first lenses, made aplanatic with two general surfaces of revolution2. For later authors remained only to vary image scale to non-zero values, and to adapt the design method to computer use.

Petrin, Christopher; Reich, David; Schmitz, Sven; Elbing, Brian

2016-11-01

A scaled model of a notional helicopter rotor hub was tested in the 48" Garfield Thomas Water Tunnel at the Applied Research Laboratory Penn State. LDV and PIV measurements in the far-wake consistently showed a six-per-revolution flow structure, in addition to stronger two- and four-per-revolution structures. These six-per-revolution structures persisted into the far-field, and have no direct geometric counterpart on the hub model. The current study will examine the Reynolds number dependence of these structures and present higher-order statistics of the turbulence within the wake. In addition, current activity using the EFPL Large Water Tunnel at Oklahoma State University will be presented. This effort uses a more canonical configuration to identify the source for these six-per-revolution structures, which are assumed to be a non-linear interaction between the two- and four-per-revolution structures.

2016-01-01

Significant sociopolitical changes in recent decades have not only influenced the nursing profession, but also the entire Iranian healthcare system. This study describes the historical evolution of the nursing profession within a sociopolitical context. This historical review of unpublished and published literature endorsed personal accounts of historic events by 14 of the oldest nurses in Iran chosen through purposive sampling method, as they shared their nursing experiences. Individual recollections were collected through in-depth and semi-structured interviews and later analyzed through oral history analysis method. From the results, the 3 categories of the White Revolution, the Islamic Revolution, and Iran-Iraq war and 8 subcategories emerged, where participants identified factors that fundamentally changed the Iranian nursing profession. The nursing profession continues to develop and help revise policies to improve the healthcare system and quality of care. The findings of this study facilitate the better understanding of the influence of sociopolitical events on the nursing profession and guide the revision or development of new healthcare policies.

Mechanical systems with closed orbits on manifolds of revolution

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kudryavtseva, E A; Fedoseev, D A

We study natural mechanical systems describing the motion of a particle on a two-dimensional Riemannian manifold of revolution in the field of a central smooth potential. We obtain a classification of Riemannian manifolds of revolution and central potentials on them that have the strong Bertrand property: any nonsingular (that is, not contained in a meridian) orbit is closed. We also obtain a classification of manifolds of revolution and central potentials on them that have the 'stable' Bertrand property: every parallel is an 'almost stable' circular orbit, and any nonsingular bounded orbit is closed. Bibliography: 14 titles.

Three centuries later, just before the French Revolution, it became an establishment of care mainly destined to receive the patients, to feed them, take care of them and if possible cure them. This medicalization of the Hôtel-Dieu de Paris is related to the progressive emergence of the medical function, which resulted in the creation and the development of a doctor's and surgeon's profession, but also in the development of the apothecary and its drugs. In this context, the diet plays a central part, because it happens to supplies. It would not be until the eve of the French Revolution that it would be integrated in the doctor's prescription and became a dietetic item.

Separated flow over bodies of revolution using an unsteady discrete-vorticity cross wake. Part 2: Computer program description

NASA Technical Reports Server (NTRS)

Marshall, F. J.; Deffenbaugh, F. D.

1974-01-01

A method is developed to determine the flow field of a body of revolution in separated flow. The computer was used to integrate various solutions and solution properties of the sub-flow fields which made up the entire flow field without resorting to a finite difference solution to the complete Navier-Stokes equations. The technique entails the use of the unsteady cross flow analogy and a new solution to the two-dimensional unsteady separated flow problem based upon an unsteady, discrete-vorticity wake. Data for the forces and moments on aerodynamic bodies at low speeds and high angle of attack (outside the range of linear inviscid theories) such that the flow is substantially separated are produced which compare well with experimental data. In addition, three dimensional steady separated regions and wake vortex patterns are determined. The computer program developed to perform the numerical calculations is described.

Differences in pedal forces during recumbent cycling in adolescents with and without cerebral palsy

Background We showed that subjects with cerebral palsy had greater transverse and frontal plane hip and knee motion, increased duration of muscle activity, increased cocontraction, and decreased efficiency during recumbent cycling than subjects with typical development. However, it is also important to understand the forces exerted on the pedals. The purpose of this report was to compare pedal forces during cycling between adolescents with and without cerebral palsy. Methods Ten subjects (3 male, 7 female) with spastic diplegic or quadriplegic cerebral palsy (15.6 years, SD 1.8) and 10 subjects (3 male, 7 female) with typical development (14.9 years, SD 1.4) cycled on a stationary recumbent cycle at 30 and 60 revolutions per minute if able. Three-dimensional piezoelectric force transducers measured pedal forces. Data were analyzed using two-way ANOVAs. Findings Subjects with cerebral palsy spent a smaller percentage (P < .001, r2 = .09, power = 1.0) of the revolution applying positive force (pushing into the pedal during the extension phase) and a greater percentage (P < .001, r2 = .09, power = 1.0) of the revolution applying negative force (pulling away from the pedal during the flexion phase). There was no effect of cadence and no interaction effect. Interpretation These findings compliment our earlier findings of altered joint kinematics and muscle activity indicating that subjects with cerebral palsy and typical development have different cycling strategies. Methods to increase the duration of the positive force may allow subjects with CP to cycle more successfully and cycle vigorously enough to reach a heart rate necessary for improving fitness.

Post-green revolution advances made in biotechnology paved the way of cultivating the high-yielding, stress and disease resistant genetically modified (GM) varieties of wheat, rice, maize cotton and several other crops. The recent rapid commercialization of the genetically modified crops in Asia, Americas and Australia indicates the potentiality of this new technology. GM crops give higher yields and are rich in nutritional values containing vitamins and minerals and can thus can help to alleviate hunger and malnutrition of the growing population in the under developed and developing countries. It could also be possible to develop more biotic and abiotic stress resistant genotypes in these crops where it was difficult to develop due to the unavailability of genes of resistance in the crossing germplasms. However, further research and investigations are needed to popularize the cultivation of these crops in different parts of the world. This review provides an insight of the impact of GM crops on contemporary agriculture across the past few decades, traces its' history across time, highlights new achievements and breakthroughs and discusses the future implication of this powerful technology in the coming few decades.

Virtual war, military revolutions, and networks: a guide through the concepts from an Australian perspective

Bowley, Dean K.; Gaertner, Paul S.

2003-07-01

In this paper the argument is made that the offensive fire support organisation and doctrine, born of the "indirect fire revolution" of the first world war, is the start point for distributed sensors, shooters and deciders that may be transferred to a joint force; that the culture of directive control and mission orders developed by the German Army in 1918 and then adopted by most western armies is the start point for the culture required to achieve "self synchronisation" and that the network developed for the air defence of carrier battle groups is the start point for developing a networked ground manoeuvre force. We discuss the strategic expectations of network centric warfare, a "virtual war" scenario and the inherent vulnerabilities. The current level of understanding and implementation in specific areas is analysed and lessons for general application are developed and the potential payoff identified. Three broad operational domains are investigated, networked platform versus platform warfare between states, guerrilla/counter-insurfence operations and the emerging domain of "netwars" (terror organisations and criminal gangs).

From satellite altimetry to operational oceanography and Argo: three revolutions in oceanography (Fridtjof Nansen Medal Lecture)

NASA Astrophysics Data System (ADS)

Le Traon, P. Y.

2012-04-01

The launch of the US/French mission Topex/Poseidon (T/P) (CNES/NASA) in August 1992 was the start of a revolution in oceanography. For the first time, a very precise altimeter system optimized for large scale sea level and ocean circulation observations was flying. Topex/Poseidon revolutionized our vision and understanding of the ocean. It provided new views of the large scale seasonal and interannual sea level and ocean circulation variations. T/P alone could not observe the mesoscale circulation. In the 1990s, the ESA satellites ERS-1/2 were flying simultaneously with T/P. The ERS-1/2 orbit was well adapted for mesoscale circulation sampling but the orbit determination and altimeter performance were much less precise than for T/P. We demonstrated that we could use T/P as a reference mission for ERS-1/2 and bring the ERS-1/2 data to an accuracy level comparable to T/P. This was an essential first step for the merging of T/P and ERS-1/2. The second step required the development of a global optimal interpolation method. Near real time high resolution global sea level anomaly maps were then derived. These maps have been operationally produced as part of the SSALTO/DUACS system for the last 15 years. They are now widely used by the oceanographic community and have contributed to a much better understanding and recognition of the role and importance of mesoscale dynamics. The unique capability of satellite altimetry to observe the global ocean in near real time at high resolution was essential to the development of global ocean forecasting, a second revolution in oceanography. The Global Ocean Data Assimilation Experiment (GODAE) (1998-2008) was phased with the T/P and ERS-1/2 successors (Jason-1 and ENVISAT) and was instrumental in the development of global operational oceanography capabilities. Europe played a leading role in GODAE. In 1998, the global in-situ observing system was inadequate for the global scope of GODAE. This led to the development of Argo, an initial joint venture between CLIVAR and GODAE. Argo has been an outstanding success. The 3000 Argo profiling floats now provide the most important global in-situ observations to monitor and understand the role of the ocean on the earth climate. This is a third revolution in oceanography. I was lucky enough to be involved with many colleagues and friends in these three revolutions or breakthroughs in oceanography. The presentation will provide some historical background on the development of the SSALTO/DUACS merged altimeter products and an overview of their utility and use for ocean research and operational oceanography. I will thengo throughthe development of operational oceanography and Argo over the past 15 years focussing on European contributions, in particular, in the framework of the GMES Marine Service, EuroGOOSand the Euro-Argo research infrastructure. Perspectives and new challenges for the integrated global ocean observing system will be finally discussed.

Universality of accelerating change

NASA Astrophysics Data System (ADS)

Eliazar, Iddo; Shlesinger, Michael F.

2018-03-01

On large time scales the progress of human technology follows an exponential growth trend that is termed accelerating change. The exponential growth trend is commonly considered to be the amalgamated effect of consecutive technology revolutions - where the progress carried in by each technology revolution follows an S-curve, and where the aging of each technology revolution drives humanity to push for the next technology revolution. Thus, as a collective, mankind is the 'intelligent designer' of accelerating change. In this paper we establish that the exponential growth trend - and only this trend - emerges universally, on large time scales, from systems that combine together two elements: randomness and amalgamation. Hence, the universal generation of accelerating change can be attained by systems with no 'intelligent designer'.

Lake, Mark S.; Warren, Peter A.; Peterson, Lee D.

1996-01-01

NASA Langley Research Center is developing concepts for an advanced spacecraft, called LidarTechSat, to demonstrate key structures and mechanisms technologies necessary to deploy a segmented telescope reflector. Achieving micron-accuracy deployment requires significant advancements in deployment mechanism design, such as the revolute joint presented herein. The joint exhibits load-cycling response that is essentially linear with less than 2% hysteresis, and the joint rotates with less than 7 mN-m (1 in-oz) of resistance. A prototype reflector metering truss incorporating the joint exhibits only a few microns of kinematic error under repected deployment and impulse loading. No other mechanically deployment structure found in the literature has been demonstrated to be this kinematically accurate.

Clinical oncology is in the midst of a genomic revolution, as molecular insights redefine our understanding of cancer biology. Greater awareness of the distinct aberrations that drive carcinogenesis is also contributing to a growing armamentarium of genomically targeted therapies. Although much work remains to better understand how to combine and sequence these therapies, improved outcomes for patients are becoming manifest. As we welcome this genomic revolution in cancer care, oncologists also must grapple with a number of practical problems. Costs of cancer care continue to grow, with targeted therapies responsible for an increasing proportion of spending. Rising costs are bringing the concept of value into sharper focus and challenging the oncology community with implementation of value-based cancer care. This article explores the ways that the genomic revolution is transforming cancer care, describes various frameworks for considering the value of genomically targeted therapies, and outlines key challenges for delivering on the promise of personalized cancer care. It highlights practical solutions for the implementation of value-based care, including investment in biomarker development and clinical trials to improve the efficacy of targeted therapy, the use of evidence-based clinical pathways, team-based care, computerized clinical decision support, and value-based payment approaches.

Contact solution algorithms

NASA Technical Reports Server (NTRS)

Tielking, John T.

1989-01-01

Two algorithms for obtaining static contact solutions are described in this presentation. Although they were derived for contact problems involving specific structures (a tire and a solid rubber cylinder), they are sufficiently general to be applied to other shell-of-revolution and solid-body contact problems. The shell-of-revolution contact algorithm is a method of obtaining a point load influence coefficient matrix for the portion of shell surface that is expected to carry a contact load. If the shell is sufficiently linear with respect to contact loading, a single influence coefficient matrix can be used to obtain a good approximation of the contact pressure distribution. Otherwise, the matrix will be updated to reflect nonlinear load-deflection behavior. The solid-body contact algorithm utilizes a Lagrange multiplier to include the contact constraint in a potential energy functional. The solution is found by applying the principle of minimum potential energy. The Lagrange multiplier is identified as the contact load resultant for a specific deflection. At present, only frictionless contact solutions have been obtained with these algorithms. A sliding tread element has been developed to calculate friction shear force in the contact region of the rolling shell-of-revolution tire model.

Experimental aerodynamic characteristics for a cylindrical body of revolution with various noses at angles of attack from 0 deg to 58 deg and Mach numbers from 0.6 to 2.0

Jorgensen, L. H.; Nelson, E. R.

1974-01-01

An experimental investigation was conducted to determine the effect of forebody geometry, a grit ring around the nose, Reynolds number, Mach number, and angle of attack on the aerodynamic characteristics of a body of revolution. Aerodynamic force and moment characteristics were measured for a cylindrical body with tangent ogive noses of fineness ratio 2.5, 3.0, 3.5, and 5.0. The cylindrical body was tested with an ogive nose having a rounded tip and an ogive nose with two different nose strake arrangements. Aerodynamic configurations were tested at various Mach numbers, angles of attack, and Reynolds numbers. The data demonstrate that the aerodynamic characteristics for a body of revolution can be significantly affected by changes in nose fineness ratio, nose bluntness, Reynolds number, Mach number, and, of course, angle of attack. Nose strakes increased the normal forces but had little effect on the side forces that developed at subsonic Mach numbers for alpha greater than about 25. A grit ring around the nose had little or no effect on the aerodynamic characteristics.

For a body of revolution with afterbody side strakes, an experimental investigation was conducted in the Ames 6- by 6-Foot Wind Tunnel to determine the effects on the aerodynamic characteristics of forebody geometry, nose strakes, body side strakes, Reynolds number, Mach number, and angle of attack. Aerodynamic force and moment characteristics were measured for the straked cylindrical afterbody (cylinder fineness ratio of 7) with tangent ogive noses of fineness ratio 2.5 to 5.0. In addition, the straked cylinder afterbody was tested with an ogive nose having a rounded tip and an ogive nose with two different nose strake arrangements. The data demonstrate that the aerodynamic characteristics for a body of revolution with side strakes can be significantly affected by changes in nose fineness ratio, nose bluntness, Reynolds number, Mach number, and, of course, angle of attack. Removing the strakes from the cylindrical aftersection greatly decreased the lift, but this removal hardly changed the maximum magnitudes of the undesirable side forces that developed at angles of attack greater than about 25 deg for subsonic Mach numbers.

Fifty years of Cuba's medical diplomacy: from idealism to pragmatism.

PubMed

Feinsilver, Julie M

2010-01-01

Medical diplomacy, the collaboration between countries to simultaneously produce health benefits and improve relations, has been a cornerstone of Cuban foreign policy since the outset of the revolution fifty years ago. It has helped Cuba garner symbolic capital (goodwill, influence, and prestige) well beyond what would have been possible for a small, developing country, and it has contributed to making Cuba a player on the world stage. In recent years, medical diplomacy has been instrumental in providing considerable material capital (aid, credit, and trade), as the oil-for-doctors deals with Venezuela demonstrates. This has helped keep the revolution afloat in trying economic times. What began as the implementation of the one of the core values of the revolution, namely health as a basic human right for all peoples, has continued as both an idealistic and a pragmatic pursuit. This article examines the factors that enabled Cuba to conduct medical diplomacy over the past fifty years, the rationale behind the conduct of this type of soft power politics, the results of that effort, and the mix of idealism and pragmatism that has characterized the experience. Moreover, it presents a typology of medical diplomacy that Cuba has used over the past fifty years.

Memories of Crisis: Bohr, Kuhn, and the Quantum Mechanical ``Revolution''

NASA Astrophysics Data System (ADS)

Seth, Suman

2013-04-01

``The history of science, to my knowledge,'' wrote Thomas Kuhn, describing the years just prior to the development of matrix and wave mechanics, ``offers no equally clear, detailed, and cogent example of the creative functions of normal science and crisis.'' By 1924, most quantum theorists shared a sense that there was much wrong with all extant atomic models. Yet not all shared equally in the sense that the failure was either terribly surprising or particularly demoralizing. Not all agreed, that is, that a crisis for Bohr-like models was a crisis for quantum theory. This paper attempts to answer four questions: two about history, two about memory. First, which sub-groups of the quantum theoretical community saw themselves and their field in a state of crisis in the early 1920s? Second, why did they do so, and how was a sense of crisis related to their theoretical practices in physics? Third, do we regard the years before 1925 as a crisis because they were followed by the quantum mechanical revolution? And fourth, to reverse the last question, were we to call into the question the existence of a crisis (for some at least) does that make a subsequent revolution less revolutionary?

The circular motion for airship-like bodies has thus far been calculated only for a prolate ellipsoid of revolution (reference 1, p.133 and reference 2). In this paper, however, the circular motion of elongated bodies of revolution more nearly resembling airships will be investigated. The results will give the effect of rotation on the pressure distribution and thus yield some information as to the stresses set up in an airship in circular flight.

A departure from cognitivism: Implications of Chomsky's second revolution in linguistics.

PubMed

Schoneberger, T

2000-01-01

In 1957 Noam Chomsky published Syntactic Structures, expressing views characterized as constituting a "revolution" in linguistics. Chomsky proposed that the proper subject matter of linguistics is not the utterances of speakers, but what speakers and listeners know. To that end, he theorized that what they know is a system of rules that underlie actual performance. This theory became known as transformational grammar. In subsequent versions of this theory, rules continued to play a dominant role. However, in 1980 Chomsky began a second revolution by proposing the elimination of rules in a new theory: the principles-and-parameters approach. Subsequent writings finalized the abandonment of rules. Given the centrality of rules to cognitivism, this paper argues that Chomsky's second revolution constitutes a departure from cognitivism.

Laser backscattering analytical model of Doppler power spectra about rotating convex quadric bodies of revolution

Gong, YanJun; Wu, ZhenSen; Wang, MingJun; Cao, YunHua

2010-01-01

We propose an analytical model of Doppler power spectra in backscatter from arbitrary rough convex quadric bodies of revolution (whose lateral surface is a quadric) rotating around axes. In the global Cartesian coordinate system, the analytical model deduced is suitable for general convex quadric body of revolution. Based on this analytical model, the Doppler power spectra of cones, cylinders, paraboloids of revolution, and sphere-cones combination are proposed. We analyze numerically the influence of geometric parameters, aspect angle, wavelength and reflectance of rough surface of the objects on the broadened spectra because of the Doppler effect. This analytical solution may contribute to laser Doppler velocimetry, and remote sensing of ballistic missile that spin.

Why the Pre-Copernican Cosmological Revolution Was Not a Revolution?

NASA Astrophysics Data System (ADS)

Pacholczyk, A. G.

The 'scientific component' of the Copernican cosmological revolution followed a seemingly minor local structural change (consisting of the transposition of the Earth and the Sun), initially not affecting the global Platonic-Aristotelian spherical symmetry of the Universe and the general arrangement of astronomical bodies at sufficiently large distances from its center. Yet this change resulted in a rich 'ideological component' of the Copernican revolution in the Popperian sense; the importance of this ideological component is generally regarded as a consequence of the tensions arising from apparent contradictions between the new cosmos and several Scriptural passages (as if the previous Platonic-Aristotelian cosmos were in perfect agreement with the Scriptures, which certainly was not the case). The scientific component of the pre-Copernican cosmological revolution (replacing the plane-parallel scriptural cosmos with the spherically symmetric non-scriptural Universe of Plato and Aristotle), was a major global change in the large-scale structure of the Universe. This change took place at different times in different places in Christendom, and was by no means ideologically revolutionary: the pre-Copernican revolution had a very insignificant 'ideological component'. In this paper, after examining this transition in more detail, we shall ask the pertinent question: why did the pre-Copernican cosmological revolution not have any significant 'ideological component'? If the God-created Universe could be depicted in the opinion of the majority of Church Fathers and Schoolmen by the (non-scriptural) spherically symmetric Platonic or Aristotelian model as well as by the (scriptural) tabernacular Babylonian model, then why couldn't it be described just as well in the opinion of 17th century churchmen by the (also non-scriptural) Copernican model? The paper suggests that the tentative answers to these questions are provided by different anthropocentric ramifications of respective cosmologies which determine the difference between the ideological components of the two cosmological revolutions. At the time of the Copernican revolution, there was no conceivable alternative to a geometric conceptualization of mankind's centrality in the Universe. That is why geometric decentralization was fought against with such intensity. It took three centuries and a radically different cosmological paradigm to find another (anthropic) form of understanding this centrality, after it was seemingly lost for such a long time.

Development of X-ray spectroscopic polarimetry with bent Si crystals and CFRP substrate

NASA Astrophysics Data System (ADS)

Iizuka, Ryo; Izumiya, Takanori; Tsuboi, Yohko

2016-07-01

The light from celestial objects includes four important quantities; images, time variation, energy spectrum, and polarization. In the field of X-ray astronomy, the capabilities of the former three have remarkably developed. On the other hand, the progress for the polarimetry is considerably delayed because of technical difficulties. In order to make a breakthrough in the field of X-ray polarimetry, we have developed a new type of optics for X-ray polarimetry. The system is collecting Bragg crystal with large area and very high sensitivity for the polarization dedicated to Fe-K lines. We adopt the 400 re ection of Si(100) crystals with high sensitivity for the polarization around Fe-K lines (6 7 keV), and bent the crystals with the wide X-ray band and high S/N ratio. Furthermore, to install small area of CCD to non-focal plane, it also has the spectroscopic capability with the better resolution than that of general X-ray CCD. Our previous development was to bent Si crystals to the cylindrical shape of circle and parabola with the DLC deposition. However, for the better optics for the X-ray polarimetry, the shape should be the paraboloid of revolution to collect X-rays with high S/N ratio. We searched for the method to bent the Si crystals to the shape of the paraboloid of revolution. We devised the method to mold the crystal and the CFRP substrate simultaneously pushed to the sophisticated foundation with the paraboloid of revolution. We developed the prototype of about 8 inch in radius of one-quater size. The crystals was also bent in the circumferential direction. Therefore, the image capability examined with optical parallel beam is 0.6 degree. In this thesis, we discussed the new design for X-ray spectroscopic polarimetry, the evaluation of image capability.

A Short (Personal) Future History of Revolution 2.0.

PubMed

Spellman, Barbara A

2015-11-01

Crisis of replicability is one term that psychological scientists use for the current introspective phase we are in-I argue instead that we are going through a revolution analogous to a political revolution. Revolution 2.0 is an uprising focused on how we should be doing science now (i.e., in a 2.0 world). The precipitating events of the revolution have already been well-documented: failures to replicate, questionable research practices, fraud, etc. And the fact that none of these events is new to our field has also been well-documented. I suggest four interconnected reasons as to why this time is different: changing technology, changing demographics of researchers, limited resources, and misaligned incentives. I then describe two reasons why the revolution is more likely to catch on this time: technology (as part of the solution) and the fact that these concerns cut across social and life sciences-that is, we are not alone. Neither side in the revolution has behaved well, and each has characterized the other in extreme terms (although, of course, each has had a few extreme actors). Some suggested reforms are already taking hold (e.g., journals asking for more transparency in methods and analysis decisions; journals publishing replications) but the feared tyrannical requirements have, of course, not taken root (e.g., few journals require open data; there is no ban on exploratory analyses). Still, we have not yet made needed advances in the ways in which we accumulate, connect, and extract conclusions from our aggregated research. However, we are now ready to move forward by adopting incremental changes and by acknowledging the multiplicity of goals within psychological science. © The Author(s) 2015.

Current developmental toxicity testing adheres largely to protocols suggested in 1966 involving the administration of test compound to pregnant laboratory animals. After more than 50 years of embryo-fetal development testing, are we ready to consider a different approach to human developmental toxicity testing? A workshop was held under the auspices of the Developmental and Reproductive Toxicology Technical Committee of the ILSI Health and Environmental Sciences Institute to consider how we might design developmental toxicity testing if we started over with 21st century knowledge and techniques (revolution). We first consider what changes to the current protocols might be recommended to make them more predictive for human risk (evolution). The evolutionary approach includes modifications of existing protocols and can include humanized models, disease models, more accurate assessment and testing of metabolites, and informed approaches to dose selection. The revolution could start with hypothesis-driven testing where we take what we know about a compound or close analog and answer specific questions using targeted experimental techniques rather than a one-protocol-fits-all approach. Central to the idea of hypothesis-driven testing is the concept that testing can be done at the level of mode of action. It might be feasible to identify a small number of key events at a molecular or cellular level that predict an adverse outcome and for which testing could be performed in vitro or in silico or, rarely, using limited in vivo models. Techniques for evaluating these key events exist today or are in development. Opportunities exist for refining and then replacing current developmental toxicity testing protocols using techniques that have already been developed or are within reach. © 2018 The Authors.

On decoding and rewriting genomes: a psychoanalytical reading of a scientific revolution.

PubMed

Zwart, Hub

2012-08-01

In various documents the view emerges that contemporary biotechnosciences are currently experiencing a scientific revolution: a massive increase of pace, scale and scope. A significant part of the research endeavours involved in this scientific upheaval is devoted to understanding and, if possible, ameliorating humankind: from our genomes up to our bodies and brains. New developments in contemporary technosciences, such as synthetic biology and other genomics and "post-genomics" fields, tend to blur the distinctions between prevention, therapy and enhancement. An important dimension of this development is "biomimesis": i.e. the tendency of novel technologies and materials to mimic or plagiarize nature on a molecular and microscopic level in order to optimise prospects for the embedding of technological artefacts in natural systems such as human bodies and brains. In this paper, these developments are read and assessed from a psychoanalytical perspective. Three key concepts from psychoanalysis are used to come to terms with what is happening in research laboratories today. After assessing the general profile of the current revolution in this manner, I will focus on a particular case study, a line of research that may serve as exemplification of the vicissitudes of contemporary technosciences, namely viral biomaterials. Viral life forms can be genetically modified (their genomes can be rewritten) in such a manner that they may be inserted in human bodies in order to produce substances at specific sites such as hormones (testosterone), neurotransmitters (dopamine), enzymes (insulin) or bone and muscle tissue. Notably, certain target groups such as top athletes, soldiers or patients suffering from degenerative diseases may become the pioneers serving as research subjects for novel applications. The same technologies can be used for various purposes ranging from therapy up to prevention and enhancement.

To analyze the impact of the Tunisian Revolution on suicide and homicide patterns in Tunisia. It is a retrospective, cross-sectional study, including all the cases of homicides and suicides that occurred during an 8-year period (2007-2014) in Northern Tunisia. We compared data before and after the revolution. After the revolution, the number of suicides rose 1.7 times, with a prevalence rising from 1.8 to 3.12 suicides per 100,000 persons per year. Homicides rose 1.3 times after the revolution. For both manner of death, victims were mostly males, aged between 20 and 39 years, living in urban areas. Hanging and self-immolation rose, respectively, 1.8 and 3 times after 2011. We observed suicide cases most frequently occurred in public places and in front of public administration after 2011. Homicide victims' profile and circumstances showed a single variation which is an increase in number of cases happening in rural areas. Our results proved a short-term impact of the transition period on homicides and suicides. Urgent preventive measures are needed especially to decrease the suicide rates.

Hua Loo-Keng's Popularization of Mathematics and the Cultural Revolution.

PubMed

Hudeček, Jiří

2017-09-01

Before 1966, Chinese mathematician Hua Loo-Keng had singled out "Two Methods" as a way to truly applied and useful mathematics. The Overall Planning Method, based on the Critical Path Method widely used in USA, mostly appealed to middle and upper management. This limited its spread during the Cultural Revolution. The Optimum Selection Method, also of US origin, was more mass-oriented and ready for popularization. Nevertheless, Hua met resistance from leftist radicals, whose ideological objections sprang from an underlying power struggle. Hua built popularization teams, mostly from talented younger people whose careers were disrupted by the Cultural Revolution, and thus opened a path for many of them to important roles in China's scientific infrastructure after 1976. Hua Loo-Keng's efforts, while interrupted during the Cultural Revolution and the subsequent political campaigns, were also helped by the populist ethos of the movement, and by the lack of other non-political endeavors at that time. In this sense, the Cultural Revolution gave Hua Loo-Keng's popularization its importance and long-term impact. Copyright © 2017 Elsevier Ltd. All rights reserved.

Development of solid-lubricated ball-screws for use in space

NASA Technical Reports Server (NTRS)

Chiba, Masatoshi; Gyougi, Toru; Nishimura, Makoto; Seki, Katsumi

1991-01-01

Ball-screws lubricated by solid lubricant films containing molybdenum disulphide are developed. The ball-screws (shaft diameter: phi 25 mm, length: 667 mm) were operated under a load of 40 to 120 N at a speed of 1.5 to 200 rpm at 10(exp -5) Pa. First, ball-screws made of stainless steel SUS 440C were studied using test equipment originally designed for this study. To reduce weight, the next step taken was to develop a ball-screw made of 6Al-4V-titanium. Long wear-life of more than 1 x 10(exp 7) revolutions was achieved with solid lubricated ball-screws made of SUS 440C and 6Al-4V-titanium in a hard vacuum. According to the surface profile of the shaft measured after 1 x 10(exp 7) revolutions, more solid lubricant remained on the surface of 6Al-4V-titanium than that of stainless steel. Auger and EPMA analysis confirmed lubrication was maintained by solid lubricant on nuts and screws after the lubricant films on the balls were worn off.

Analysis of dynamic capacity of low-contact-ratio spur gears using Lundberg-Palmgren theory

NASA Technical Reports Server (NTRS)

Coy, J. J.

1975-01-01

A concise mathematical model is developed for surface fatigue life of low-contact-ratio spur gears. The expected fatigue life of the pinion, gear, or gear sets may be calculated from the model. An equation for the dynamic capacity of the gear set was also derived in terms of the transmitted tangential tooth load which will give a 10-percent fatigue life of one million pinion revolutions. The theoretical life was compared with experimental data for a set of VAR AISI 9310 gears operating at a Hertz stress of 1.71X10 to the 9th power newtons per square meter (248,000 psi) and 10 000 revolutions per minute. Good agreement was obtained between the experimental and theoretical surface fatigue life of the gears.

Transnational networks, diffusion dynamics, and electoral revolutions in the postcommunist world

NASA Astrophysics Data System (ADS)

Bunce, Valerie; Wolchik, Sharon L.

2007-05-01

Since 1996, eight elections have taken place in postcommunist Europe and Eurasia that have replaced illiberal with liberal governments. There is ample evidence that these “electoral revolutions” reflected the cross-national diffusion of a distinctive model of regime change that was developed elsewhere and that was designed to promote democratization in authoritarian political contexts featuring semi-competitive elections. This electoral model spread throughout the postcommunist region because of both shared perceptions by opposition groups of similar local conditions and the existence of transnational democracy promotion networks that included local, regional and American participants. As these revolutions spread, however, they were less successful in carrying through democratic change-in part because local conditions were less supportive and in part because authoritarian leaders and their international allies were both forewarned and forearmed.

Technology transfer: The key to successful space engineering education

NASA Astrophysics Data System (ADS)

Fletcher, L. S.; Page, R. H.

The 1990s are the threshold of the space revolution for the next century. This space revolution was initiated by space pioneers like Tsiolkovsky, Goddard, and Oberth, who contributed a great deal to the evolution of space exploration, and more importantly, to space education. Recently, space engineering education programs for all ages have been advocated around the world, especially in Asia and Europe, as well as the U.S.A. and the Soviet Union. And yet, although space related technologies are developing rapidly, these technologies are not being incorporated successfully into space education programs. Timely technology transfer is essential to assure the continued education of professionals. This paper reviews the evolution of space engineering education and identifies a number of initiatives which could strengthen space engineering education for the next century.

An integrated computer program entitled Field Analysis of Shells of Revolution (FASOR) currently under development for NASA is described. When completed, this code will treat prebuckling, buckling, initial postbuckling and vibrations under axisymmetric static loads as well as linear response and bifurcation under asymmetric static loads. Although these modes of response are treated by existing programs, FASOR extends the class of problems treated to include general anisotropy and transverse shear deformations of stiffened laminated shells. At the same time, a primary goal is to develop a program which is free of the usual problems of modeling, numerical convergence and ill-conditioning, laborious problem setup, limitations on problem size and interpretation of output. The field method is briefly described, the shell differential equations are cast in a suitable form for solution by this method and essential aspects of the input format are presented. Numerical results are given for both unstiffened and stiffened anisotropic cylindrical shells and compared with previously published analytical solutions.

Characterizing the Performance of the Wheel Electrostatic Spectrometer

NASA Technical Reports Server (NTRS)

Johansen, M. R.; Mackey, P. J.; Holbert, E.; Clements, J. S.; Calle, C. I.

2013-01-01

A Wheel Electrostatic Spectrometer has been developed as a surveying tool to be incorporated into a Martian rover design. Electrostatic sensors with various protruding cover insulators are embedded into a prototype rover wheel. When these insulators come into contact with a surface, a charge develops on the cover insulator through tribocharging. A charge spectrum is created by analyzing the accumulated charge on each of the dissimilar cover insulators. This charge spectrum can be used to determine differences in Martian regolith properties. In this study, we analyzed the repeatability of the measurements for this sensor package and found that the sensor repeatability lies within one standard deviation of the noise in the signal. In addition, we tested the need for neutralizing the surface charge on the cover insulators and discovered a need to discharge the sensor cover insulators after each revolution. Future work includes an electronics redesign to reduce noise and a Martian pressure static elimination tool that can be used to neutralize the charge on the sensor cover insulators after each wheel revolution.

Support for international agricultural research: current status and future challenges.

PubMed

Zeigler, Robert S; Mohanty, Samarendu

2010-11-30

The success of the first Green Revolution in the form of abundant food supplies and low prices over the past two decades has diverted the world's attention from agriculture to other pressing issues. This has resulted in lower support for the agricultural research work primarily undertaken by the 15 research centers of the Consultative Group on International Agricultural Research (CGIAR). The total support in real dollars for most of the last three decades has been more or less flat although the number of centers increased from 4 to 15. However, since 2000, the funding situation has improved for the CGIAR centers, with almost all the increase coming from grants earmarked for specific research projects. Even for some centers such as the International Rice Research Institute (IRRI), the downward trend continued as late as 2006 with the budget in real dollars reaching the 1978 level of support. The recent food crisis has renewed the call for a second Green Revolution by revitalizing yield growth to feed the world in the face of growing population and a shrinking land base for agricultural use. The slowdown in yield growth because of decades of neglect in agricultural research and infrastructure development has been identified as the underlying reason for the recent food crisis. For the second Green Revolution to be successful, the CGIAR centers will have to play a complex role by expanding productivity in a sustainable manner with fewer resources. Thus, it is crucial to examine the current structure of support for the CGIAR centers and identify the challenges ahead in terms of source and end use of funds for the success of the second Green Revolution. The objective of this paper is to provide a historical perspective on the support to the CGIAR centers and to examine the current status of funding, in particular, the role of project-specific grants in rebuilding capacity of these centers. The paper will also discuss the nature of the support (unrestricted vs. project-specific grants) that will be needed for a much-desired second Green Revolution. Copyright © 2010 Elsevier B.V.

Some of the most important things in life are taken for granted, and nowhere is this truer than with light. In this article, we will look at some important milestones marking light's path from human evolution to sustainable revolution, challenges facing the modern lighting industry as well as the world we live in, and what the future promises. In a sense, a new revolution is at hand. It would be hard to overestimate the fundamental importance of light as it shapes virtually everything we sense and experience.

Common Mechanisms of DNA translocation motors in Bacteria and Viruses Using One-way Revolution Mechanism without Rotation

PubMed Central

Guo, Peixuan; Zhao, Zhengyi; Haak, Jeannie; Wang, Shaoying; Weitao, Tao

2014-01-01

Biomotors were once classified into two categories: linear motor and rotation motor. For decades, the viral DNA-packaging motor has been popularly believed to be a five-fold rotation motor. Recently, a third type of biomotor with revolution mechanism without rotation has been discovered. By analogy, rotation resembles the Earth rotating on its axis in a complete cycle every 24 hours, while revolution resembles the Earth revolving around the Sun one circle per 365 days (see animations http://nanobio.uky.edu/movie.html). The action of revolution that enables a motor free of coiling and torque has solved many puzzles and debates that have occurred throughout the history of viral DNA packaging motor studies. It also settles the discrepancies concerning the structure, stoichiometry, and functioning of DNA translocation motors. This review uses bacteriophages Phi29, HK97, SPP1, P22, T4, T7 as well as bacterial DNA translocase FtsK and SpoIIIE as examples to elucidate the puzzles. These motors use a ATPase, some of which have been confirmed to be a hexamer, to revolve around the dsDNA sequentially. ATP binding induces conformational change and possibly an entropy alteration in ATPase to a high affinity toward dsDNA; but ATP hydrolysis triggers another entropic and conformational change in ATPase to a low affinity for DNA, by which dsDNA is pushed toward an adjacent ATPase subunit. The rotation and revolution mechanisms can be distinguished by the size of channel: the channels of rotation motors are equal to or smaller than 2 nm, whereas channels of revolution motors are larger than 3 nm. Rotation motors use parallel threads to operate with a right-handed channel, while revolution motors use a left-handed channel to drive the right-handed DNA in an anti-parallel arrangement. Coordination of several vector factors in the same direction makes viral DNA-packaging motors unusually powerful and effective. Revolution mechanism avoids DNA coiling in translocating the lengthy genomic dsDNA helix could be advantage for cell replication such as bacterial binary fission and cell mitosis without the need for topoisomerase or helicase to consume additional energy.

Toledo-Pereyra, Luis H

2009-01-01

The book that Claude Bernard (1813-1878) published in 1865, the Introduction à l'Etude de la Médecine Expérimentale, fostered a revolution that we believe influenced the practice of surgery when the discipline became a scientific enterprise. In Part I, we set the stage by presenting the life and accomplishments of Bernard, by reviewing his science, and introducing his experimental medicine work. In this issue in Part II, we further analyze his book and determine the "why" of a genuine surgical revolution. What were the factors that generated this revolution, and how a new generation of surgeons learned to become better researchers, and thus better surgeons, were the main objectives of this work. Science, research, and surgery became highly intertwined and the surgeon pursued these fields of knowledge more effectively.

Accelerometers provide a measure of step-count. Reliability and validity of step-count and pedal-revolution count measurements by the GT3X+ accelerometer, placed at different anatomical locations, is absent in the literature. The purpose of this study was to investigate the reliability and validity of step and pedal-revolution counts produced by the GT3X+ placed at different anatomical locations during running and bicycling. Twenty-two healthy adults (14 men and 8 women) completed running and bicycling activity bouts (5 minutes each) while wearing 6 accelerometers: 2 each at the waist, thigh and shank. Accelerometer and video data were collected during activity. Excellent reliability and validity were found for measurements taken from accelerometers mounted at the waist and shank during running (Reliability: intraclass correlation (ICC) ≥ 0.99; standard error of measurement (SEM) ≤1.0 steps; Pearson ≥ 0.99) and at the thigh and shank during bicycling (Reliability: ICC ≥ 0.99; SEM ≤1.0 revolutions; Pearson ≥ 0.99). Excellent reliability was found between measurements taken at the waist and shank during running (ICC ≥ 0.98; SEM ≤1.6 steps) and between measurements taken at the thigh and shank during bicycling (ICC ≥ 0.99; SEM ≤1.0 revolutions). These data suggest that the GT3X+ can be used for measuring step-count during running and pedal-revolution count during bicycling. Only shank placement is recommended for both activities.

Progress in post-quantum mechanics

NASA Astrophysics Data System (ADS)

Sarfatti, Jack

2017-05-01

Newton's mechanics in the 17th century increased the lethality of artillery. Thermodynamics in the 19th led to the steam-powered industrial revolution. Maxwell's unification of electricity, magnetism and light gave us electrical power, the telegraph, radio and television. The discovery of quantum mechanics in the 20th century by Planck, Bohr, Einstein, Schrodinger, Heisenberg led to the creation of the atomic and hydrogen bombs as well as computer chips, the world-wide-web and Silicon Valley's multibillion dollar corporations. The lesson is that breakthroughs in fundamental physics, both theoretical and experimental, have always led to profound technological wealth-creating industries and will continue to do so. There is now a new revolution brewing in quantum mechanics that can be divided into three periods. The first quantum revolution was from 1900 to about 1975. The second quantum information/computer revolution was from about 1975 to 2015. (The early part of this story is told by Kaiser in his book, How the Hippies Saved Physics, how a small group of Berkeley/San Francisco physicists triggered that second revolution.) The third quantum revolution is how an extension of quantum mechanics may lead to the understanding of consciousness as a natural physical phenomenon that can emerge in many material substrates, not only in our carbon-based biochemistry. In particular, this new post-quantum mechanics may lead to naturally conscious artificial intelligence in nano-electronic machines, as well as perhaps extending human life spans to hundreds of years and more.

Importance of anticoagulation and postablation silent cerebral lesions: Subanalyses of REVOLUTION and reMARQable studies.

Silent cerebral lesions (SCLs) are a potential complication of left atrial radiofrequency ablation (RFA) procedures for paroxysmal atrial fibrillation (PAF). We aimed to compare the incidence of SCLs in patients treated with irrigated RFA multielectrode catheters (nMARQ ® Catheter group) and irrigated focal RFA catheters (NAVISTAR ® THERMOCOOL ® Catheter; TC group) after PAF ablation from subpopulation neurological assessment (SNA) cohorts of the REVOLUTION and reMARQable studies. Data from SNA cohorts in the prospective, nonrandomized REVOLUTION study (March 2011-September 2013) and the prospective, randomized, controlled reMARQable study (October 2013-November 2015) were included. The incidence of SCLs was assessed pre- and postablation using magnetic resonance imaging. Neurological deficits were assessed using the National Institutes of Health Stroke Scale, modified Rankin Scale, and Montreal Cognitive Assessment. A total of 37 patients from REVOLUTION and 76 patients from reMARQable were included in the SNA cohort of each study. In the REVOLUTION SNA cohort, the incidence of SCLs was 21.1% (4/19) in the nMARQ ® Catheter group and 5.9% (1/17) in the TC group. Findings from REVOLUTION helped inform the reMARQable study protocol's stringent anticoagulation regimen. SCL incidence was subsequently reduced in both groups (nMARQ ® Catheter, 7.9%; TC, 3.3%). No permanent neurological deficits were observed. Adherence to a stringent anticoagulation regimen prior to and during ablation procedures appears to be an important factor in minimizing the risk of SCL. © 2017 Wiley Periodicals, Inc.

There is a rapid transformation afoot in the rice value chain in Asia. The upstream is changing quickly-farmers are undertaking capital-led intensification and participating in burgeoning markets for land rental, fertilizer and pesticides, irrigation water, and seed, and shifting from subsistence to small commercialized farms; in some areas landholdings are concentrating. Midstream, in wholesale and milling, there is a quiet revolution underway, with thousands of entrepreneurs investing in equipment, increasing scale, diversifying into higher quality, and the segments are undergoing consolidation and vertical coordination and integration. Mills, especially in China, are packaging and branding, and building agent networks in wholesale markets, and large mills are building direct relationships with supermarkets. The downstream retail segment is undergoing a "supermarket revolution," again with the lead in change in China. In most cases the government is not playing a direct role in the market, but enabling this transformation through infrastructural investment. The transformation appears to be improving food security for cities by reducing margins, offering lower consumer rice prices, and increasing quality and diversity of rice. This paper discusses findings derived from unique stacked surveys of all value chain segments in seven zones, more and less developed, around Bangladesh, China, India, and Vietnam. © 2014 New York Academy of Sciences.

The quadruple squeeze: defining the safe operating space for freshwater use to achieve a triply green revolution in the anthropocene.

PubMed

Rockström, Johan; Karlberg, Louise

2010-05-01

Humanity has entered a new phase of sustainability challenges, the Anthropocene, in which human development has reached a scale where it affects vital planetary processes. Under the pressure from a quadruple squeeze-from population and development pressures, the anthropogenic climate crisis, the anthropogenic ecosystem crisis, and the risk of deleterious tipping points in the Earth system-the degrees of freedom for sustainable human exploitation of planet Earth are severely restrained. It is in this reality that a new green revolution in world food production needs to occur, to attain food security and human development over the coming decades. Global freshwater resources are, and will increasingly be, a fundamental limiting factor in feeding the world. Current water vulnerabilities in the regions in most need of large agricultural productivity improvements are projected to increase under the pressure from global environmental change. The sustainability challenge for world agriculture has to be set within the new global sustainability context. We present new proposed sustainability criteria for world agriculture, where world food production systems are transformed in order to allow humanity to stay within the safe operating space of planetary boundaries. In order to secure global resilience and thereby raise the chances of planet Earth to remain in the current desired state, conducive for human development on the long-term, these planetary boundaries need to be respected. This calls for a triply green revolution, which not only more than doubles food production in many regions of the world, but which also is environmentally sustainable, and invests in the untapped opportunities to use green water in rainfed agriculture as a key source of future productivity enhancement. To achieve such a global transformation of agriculture, there is a need for more innovative options for water interventions at the landscape scale, accounting for both green and blue water, as well as a new focus on cross-scale interactions, feed-backs and risks for unwanted regime shifts in the agro-ecological landscape.

AIDS and population "control".

PubMed

Piel, G

1994-02-01

Many people believe that the AIDS pandemic will end the population explosion, especially in Africa, where population growth is very high and poverty reigns. Africans make up 10 million of all 15 million HIV- infected persons worldwide. Yet, the proposition that AIDS will sole population explosion does not stand up to reason. About 200 million people in Africa will be HIV infected by 2010, but the loss of 200 million people would not slow population growth. The 14th century's Black Death killed more than 50% of the European population, but by 1750 Europe had reached the population size it would have reached without the Black Death. The 200 million people who died violent deaths between the start and end of the two World Wars did not stop world population growth from peaking in 1970 at about 2%. When Malthus made his prediction that human population would crash, the industrial revolution had already helped production outrun population growth. Today all industrial countries are either at or near zero population growth and have completed the demographic transition (from near zero growth in 1600 with high births and death rates and a 25-year life expectancy, to near zero growth in 1990s at low death and birth rates with a 75-year life expectancy). Mass education, sanitation, primary medicine, and the green revolution have already reduced death rates and increased life expectancy in developing countries. Thus, they have entered the first phase of the demographic transition. Some developing countries are in the second phase; birth rate decline For example, in India and China, fertility has fallen from 6 to 4 in India and is at 2.3 in China. The AIDS pandemic is a diversion of physical and human resources from helping developing countries pass through the demographic transition more quickly to achieve sustainable development. This delay is likely to effect a larger maximum population. The industrial revolution has shifted the key to stopping population growth the people dying to people living.

Politics and the life sciences: an unfinished revolution.

Johnson, Gary R

2011-01-01

Politics and the life sciences--also referred to as biopolitics--is a field of study that seeks to advance knowledge of politics and promote better policymaking through multidisciplinary analysis that draws on the life sciences. While the intellectual origins of the field may be traced at least into the 1960s, a broadly organized movement appeared only with the founding of the Association for Politics and the Life Sciences (APLS) in 1980 and the establishment of its journal, Politics and the Life Sciences ( PLS ), in 1982. This essay--contributed by a past journal editor and association executive director--concludes a celebration of the association's thirtieth anniversary. It reviews the founding of the field and the association, as well as the contributions of the founders. It also discusses the nature of the empirical work that will advance the field, makes recommendations regarding the identity and future of the association, and assesses the status of the revolution of which the association is a part. It argues that there is progress to celebrate, but that this revolution--the last of three great scientific revolutions--is still in its early stages. The revolution is well-started, but remains unfinished.

Computer code for scattering from impedance bodies of revolution. Part 3: Surface impedance with s and phi variation. Analytical and numerical results

1993-01-01

The third phase of the development of the computer codes for scattering by coated bodies that has been part of an ongoing effort in the Electromagnetics Laboratory of the Electrical Engineering and Computer Science Department at the University of Illinois at Chicago is described. The work reported discusses the analytical and numerical results for the scattering of an obliquely incident plane wave by impedance bodies of revolution with phi variation of the surface impedance. Integral equation formulation of the problem is considered. All three types of integral equations, electric field, magnetic field, and combined field, are considered. These equations are solved numerically via the method of moments with parametric elements. Both TE and TM polarization of the incident plane wave are considered. The surface impedance is allowed to vary along both the profile of the scatterer and in the phi direction. Computer code developed for this purpose determines the electric surface current as well as the bistatic radar cross section. The results obtained with this code were validated by comparing the results with available results for specific scatterers such as the perfectly conducting sphere. Results for the cone-sphere and cone-cylinder-sphere for the case of an axially incident plane were validated by comparing the results with the results with those obtained in the first phase of this project. Results for body of revolution scatterers with an abrupt change in the surface impedance along both the profile of the scatterer and the phi direction are presented.

Energy and the English Industrial Revolution.

PubMed

Wrigley, E A

2013-03-13

Societies before the Industrial Revolution were dependent on the annual cycle of plant photosynthesis for both heat and mechanical energy. The quantity of energy available each year was therefore limited, and economic growth was necessarily constrained. In the Industrial Revolution, energy usage increased massively and output rose accordingly. The energy source continued to be plant photosynthesis, but accumulated over a geological age in the form of coal. This poses a problem for the future. Fossil fuels are a depleting stock, whereas in pre-industrial time the energy source, though limited, was renewed each year.

Laminar Flow About a Rotating Body of Revolution in an Axial Airstream

NASA Technical Reports Server (NTRS)

Schlichting, H.

1956-01-01

We have set ourselves the problem of calculating the laminar flow on a body of revolution in an axial flow which simultaneously rotates about its axis. The problem mentioned above, the flow about a rotating disk in a flow, which we solved some time ago, represents the first step in the calculation of the flow on the rotating body of revolution in a flow insofar as, in the case of a round nose, a small region about the front stagnation point of the body of revolution may be replaced by its tangential plane. In our problem regarding the rotating body of revolution in a flow, for laminar flow, one of the limiting cases is known: that of the body which is in an axial approach flow but does not rotate. The other limiting case, namely the flow in the neighborhood of a body which rotates but is not subjected to a flow is known only for the rotating circular cylinder, aside from the rotating disk. In the case of the cylinder one deals with a distribution of the circumferential velocity according to the law v = omega R(exp 2)/r where R signifies the cylinder radius, r the distance from the center, and omega the angular velocity of the rotation. The velocity distribution as it is produced here by the friction effect is therefore the same as in the neighborhood of a potential vortex. When we treat, in what follows, the general case of the rotating body of revolution in a flow according to the calculation methods of Prandtl's boundary-layer theory, we must keep in mind that this solution cannot contain the limiting case of the body of revolution which only rotates but is not subjected to a flow. However, this is no essential limitation since this case is not of particular importance for practical purposes.

A brief history of phosphorus: from the philosopher's stone to nutrient recovery and reuse.

PubMed

Ashley, K; Cordell, D; Mavinic, D

2011-08-01

The element phosphorus has no substitute in sustaining all life and food production on our planet. Yet today's phosphorus use patterns have resulted in both a global environmental epidemic of eutrophication and led to a situation where the future availability of the world's main sources of phosphorus is uncertain. This paper examines the important history of human interference with the phosphorus cycle from initial discovery to present, highlighting key interrelated events and consequences of the Industrial Revolution, Sanitation Revolution and Green Revolution. Whilst these events led to profound advances in technology, public health and food production, they have fundamentally broken the global phosphorus cycle. It is clear a 'Fourth Revolution' is required to resolve this dilemma and ensure humanity can continue to feed itself into the future while protecting environmental and human health.

Mass spectrometry: a revolution in clinical microbiology?

Lavigne, Jean-Philippe; Espinal, Paula; Dunyach-Remy, Catherine; Messad, Nourredine; Pantel, Alix; Sotto, Albert

2013-02-01

Recently, different bacteriological laboratory interventions that decrease reporting time have been developed. These promising new broad-based techniques have merit, based on their ability to identify rapidly many bacteria, organisms difficult to grow or newly emerging strains, as well as their capacity to track disease transmission. The benefit of rapid reporting of identification and/or resistance of bacteria can greatly impact patient outcomes, with an improvement in the use of antibiotics, in the reduction of the emergence of multidrug resistant bacteria and in mortality rates. Different techniques revolve around mass spectrometry (MS) technology: matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS), PCR combined with electrospray ionization-mass spectrometry (PCR/ESIMS), iPLEX MassArray system and other new evolutions combining different techniques. This report emphasizes the (r)evolution of these technologies in clinical microbiology.

Mixed Models and Reduction Techniques for Large-Rotation, Nonlinear Analysis of Shells of Revolution with Application to Tires

NASA Technical Reports Server (NTRS)

Noor, A. K.; Andersen, C. M.; Tanner, J. A.

1984-01-01

An effective computational strategy is presented for the large-rotation, nonlinear axisymmetric analysis of shells of revolution. The three key elements of the computational strategy are: (1) use of mixed finite-element models with discontinuous stress resultants at the element interfaces; (2) substantial reduction in the total number of degrees of freedom through the use of a multiple-parameter reduction technique; and (3) reduction in the size of the analysis model through the decomposition of asymmetric loads into symmetric and antisymmetric components coupled with the use of the multiple-parameter reduction technique. The potential of the proposed computational strategy is discussed. Numerical results are presented to demonstrate the high accuracy of the mixed models developed and to show the potential of using the proposed computational strategy for the analysis of tires.

Embracing a Revolution - Telemedicine.

PubMed

Dheer, Ajay; Chaturvedi, R K

2005-01-01

The recent advances in information and communication technologies offer real and practical opportunities to health professionals to share expertise and resources in health care over distances. For a country like India with pockets of medical excellence surrounded by a vast number of badly equipped hospitals with limited specialists, telemedicine could revolutionize health care. The potential of telemedicine seem to be vital in avoiding the frame of travel, in timely getting specialist advise to remote areas, minimizing the cost and of course an opportunity to learn from each other. In developed countries the technological advancement and research aims primarily to satiate the needs of their armed forces and to ensure tactical and technical supremacy. The medical community in the Indian Armed Forces should harness the technologies and embrace this revolution of the information age to provide world class combat casualty care.

Common mechanisms of DNA translocation motors in bacteria and viruses using one-way revolution mechanism without rotation.

PubMed

Guo, Peixuan; Zhao, Zhengyi; Haak, Jeannie; Wang, Shaoying; Wu, Dong; Meng, Bing; Weitao, Tao

2014-01-01

Biomotors were once described into two categories: linear motor and rotation motor. Recently, a third type of biomotor with revolution mechanism without rotation has been discovered. By analogy, rotation resembles the Earth rotating on its axis in a complete cycle every 24h, while revolution resembles the Earth revolving around the Sun one circle per 365 days (see animations http://nanobio.uky.edu/movie.html). The action of revolution that enables a motor free of coiling and torque has solved many puzzles and debates that have occurred throughout the history of viral DNA packaging motor studies. It also settles the discrepancies concerning the structure, stoichiometry, and functioning of DNA translocation motors. This review uses bacteriophages Phi29, HK97, SPP1, P22, T4, and T7 as well as bacterial DNA translocase FtsK and SpoIIIE or the large eukaryotic dsDNA viruses such as mimivirus and vaccinia virus as examples to elucidate the puzzles. These motors use ATPase, some of which have been confirmed to be a hexamer, to revolve around the dsDNA sequentially. ATP binding induces conformational change and possibly an entropy alteration in ATPase to a high affinity toward dsDNA; but ATP hydrolysis triggers another entropic and conformational change in ATPase to a low affinity for DNA, by which dsDNA is pushed toward an adjacent ATPase subunit. The rotation and revolution mechanisms can be distinguished by the size of channel: the channels of rotation motors are equal to or smaller than 2 nm, that is the size of dsDNA, whereas channels of revolution motors are larger than 3 nm. Rotation motors use parallel threads to operate with a right-handed channel, while revolution motors use a left-handed channel to drive the right-handed DNA in an anti-chiral arrangement. Coordination of several vector factors in the same direction makes viral DNA-packaging motors unusually powerful and effective. Revolution mechanism that avoids DNA coiling in translocating the lengthy genomic dsDNA helix could be advantageous for cell replication such as bacterial binary fission and cell mitosis without the need for topoisomerase or helicase to consume additional energy.

Which Way Is Up? Thomas S. Kuhn's Analogy to Conceptual Development in Childhood

NASA Astrophysics Data System (ADS)

Levine, Alexander T.

In the Preface to his Structure Of Scientific Revolutions, Thomas S. Kuhn let it be known that his view of scientific development was indebted to the work of pioneering developmental psychologist Jean Piaget. Piaget's model of conceptual development in childhood, on which the child passes through several discontinuous stages, served as the template for Kuhn's reading of the history of a scientific discipline, on which mutually incommensurable periods of normal science are separated by scientific revolutions. The analogy to conceptual change in childhood pervades Kuhn's corpus, serving as the central motif in his well-known essays, A Function for Thought Experiments and Second Thoughts on Paradigms. But it is deeply problematic. For as a careful student of Piaget might note, Piaget, and the developmental psychologists he inspired, relied on the same analogy, but with the order of epistemic dependencies reversed. One begins to worry that Kuhn's use of the analogy, and its subsequent re-use by developmental psychologists, sneaks a vicious circularity into our understanding of important processes. This circularity is grounds for some concern on the part of science educators accustomed to employing such Kuhnian notions as incommensurability and paradigm.

Agriculture in Africa: strategies to improve and sustain smallholder production systems.

PubMed

Jama, Bashir; Pizarro, Gonzalo

2008-01-01

Agricultural development lies at the heart of poverty reduction and increased food security of most developing nations. Sub-Saharan Africa (hereafter referred to as Africa) is, however, the only region in the world where per capita agricultural productivity has remained stagnant over the past 40 years. In Asia and Latin America, the use of tailored techniques and technologies has transformed agricultural practice and its productivity, leading to what has been called the "green revolution." The dissemination of uniquely African green revolution technologies has not occurred on the continent. This chapter will argue that the same results in increased productivity and food security can be achieved in Africa if the appropriate investments are made in key interventions: soil fertility improvement, improved seeds, water management, market access, extension services, access to credit, and improvements in weather forecasting. Where these have happened, even partially, the outcome has been remarkable. However, bringing them to scale in ways that sustainably increase agricultural productivity and alleviate poverty requires increased investments and innovative institutional arrangements. Fortunately, several research and development projects on the continent, including the Millennium Villages Project, are providing valuable insights. Finally, this chapter outlines the key remaining challenges.
