Thermodynamics, Entropy, Information and the Efficiency of Solar Cells

Science.gov (United States)

Abrams, Zeev R.

For well over 50 years, the limits to photovoltaic energy conversion have been known and codified, and have played a vital role in the push for technological breakthroughs to reach—and even attempt to surpass—those limits. This limit, known as the Shockley-Queisser detailed-balance limit, was found by using only the most basic of thermodynamic assumptions, and therefore provides an upper bound that is difficult to contest without violating the laws of thermodynamics. Many different schemes have been devised to improve a solar cell's efficiency beyond this limit, with various benefits and drawbacks for each method. Since the field of solar cell research has been analyzed and dissected for so long by a large variety of researchers, it is quite hard to say or discover anything new without repeating the work of the past. The approach taken in this work is to analyze solar cells from the joint perspective of thermodynamics and information theory. These two subjects have recently been appreciated to be highly interrelated, and using the formalism of Missing Information, we can differentiate between different novel technologies, as well as devise new limits for new and existing methodologies. In this dissertation, the fundamentals of photovoltaic conversion are analyzed from the most basic of principles, emphasizing the thermodynamic parameters of the photovoltaic process. In particular, an emphasis is made on the voltage of the device, as opposed to the current. This emphasis is made since there is a direct relation between the open-circuit voltage of a solar cell and the fundamental equations of thermodynamics and the Free Energy of the system. Moreover, this relation extends to the entropy of the system, which subsequently relates to the field of Information Theory. By focusing on the voltage instead of the current, realizations are made that are not obvious to the majority or researchers in the field, and in particular to efforts of surpassing the Shockley

Quantum and Information Thermodynamics: A Unifying Framework Based on Repeated Interactions

Science.gov (United States)

Strasberg, Philipp; Schaller, Gernot; Brandes, Tobias; Esposito, Massimiliano

2017-04-01

We expand the standard thermodynamic framework of a system coupled to a thermal reservoir by considering a stream of independently prepared units repeatedly put into contact with the system. These units can be in any nonequilibrium state and interact with the system with an arbitrary strength and duration. We show that this stream constitutes an effective resource of nonequilibrium free energy, and we identify the conditions under which it behaves as a heat, work, or information reservoir. We also show that this setup provides a natural framework to analyze information erasure ("Landauer's principle") and feedback-controlled systems ("Maxwell's demon"). In the limit of a short system-unit interaction time, we further demonstrate that this setup can be used to provide a thermodynamically sound interpretation to many effective master equations. We discuss how nonautonomously driven systems, micromasers, lasing without inversion and the electronic Maxwell demon can be thermodynamically analyzed within our framework. While the present framework accounts for quantum features (e.g., squeezing, entanglement, coherence), we also show that quantum resources do not offer any advantage compared to classical ones in terms of the maximum extractable work.

Unifying three perspectives on information processing in stochastic thermodynamics.

Barato, A C; Seifert, U

2014-03-07

So far, feedback-driven systems have been discussed using (i) measurement and control, (ii) a tape interacting with a system, or (iii) by identifying an implicit Maxwell demon in steady-state transport. We derive the corresponding second laws from one master fluctuation theorem and discuss their relationship. In particular, we show that both the entropy production involving mutual information between system and controller and the one involving a Shannon entropy difference of an information reservoir like a tape carry an extra term different from the usual current times affinity. We, thus, generalize stochastic thermodynamics to the presence of an information reservoir.

Public Information Plan

International Nuclear Information System (INIS)

1984-06-01

The Public Information Plan is intended to be used in conjunction with the DOE-UMTRA Project ''Public Participation Plan'' to describe the Department of Energy's plan for involving the public in the decision-making process related to the Uranium Mill Tailings Remedial Action (UMTRA) Project. This project was authorized by Congress in the Uranium Mill Tailings Radiation Control of Act of 1978, PL95-604. The Act provides for a cooperative effort with affected states and Indian tribes for the cleanup of designated abandoned or inactive uranium mill tailings sites. The objective of the Public Information Plan of the UMTRA Project is timely and sufficient dissemination of factual information to promote understanding of the project by federal, state, and local officials, the media, special interest groups, and the general public; and thereby to encourage informed participation in the project by the public and government officials. The Uranium Mill Tailings Radiation Control Act provides for public involvement in remedial action planning, with special consideration given to landowners, Indian tribes, and the states. According to the Act, the Secretary of Energy shall hold public hearings in the states where processing sites, vicinity properties, and disposal sites are located. Public participation in the UMTRA Project will not, however, be limited to those mechanisms formally required by law. The public may also be involved informally through informational meetings, workshops, and local citizens' task forces. 12 refs., 2 figs., 1 tab

Backward transfer entropy: Informational measure for detecting hidden Markov models and its interpretations in thermodynamics, gambling and causality

Science.gov (United States)

Ito, Sosuke

2016-01-01

The transfer entropy is a well-established measure of information flow, which quantifies directed influence between two stochastic time series and has been shown to be useful in a variety fields of science. Here we introduce the transfer entropy of the backward time series called the backward transfer entropy, and show that the backward transfer entropy quantifies how far it is from dynamics to a hidden Markov model. Furthermore, we discuss physical interpretations of the backward transfer entropy in completely different settings of thermodynamics for information processing and the gambling with side information. In both settings of thermodynamics and the gambling, the backward transfer entropy characterizes a possible loss of some benefit, where the conventional transfer entropy characterizes a possible benefit. Our result implies the deep connection between thermodynamics and the gambling in the presence of information flow, and that the backward transfer entropy would be useful as a novel measure of information flow in nonequilibrium thermodynamics, biochemical sciences, economics and statistics.

Thermodynamic data for biomass conversion and waste incineration

Energy Technology Data Exchange (ETDEWEB)

Domalski, E.S.; Jobe, T.L. Jr; Milne, T.A.

1986-09-01

The general purpose of this collection of thermodynamic data of selected materials is to make property information available to the engineering community on chemical mixtures, polymers, composite materials, solid wastes, biomass, and materials not easily identifiable by a single stoichiometric formula. More than 700 materials have been compiled covering properties such as specific heat, gross heat of combustion, heat of fusion, heat of vaporization, and vapor pressure. The information was obtained from the master files of the NBS Chemical Thermodynamics Data Center, the annual issues of the Bulletin of Chemical Thermodynamics, intermittent examinations of the Chemical Abstracts subject indexes, individual articles by various authors, and other general reference sources. The compilation is organized into several broad categories; materials are listed alphabetically within each category. For each material, the physical state, information as to the composition or character of the material, the kind of thermodynamic property reported, the specific property values for the material, and citations to the reference list are given. In addition, appendix A gives an empirical formula that allows heats of combustion of carbonaceous materials to be predicted with surprising accuracy when the elemental composition is known. A spread sheet illustrates this predictability with examples from this report and elsewhere. Appendix B lists some reports containing heats of combustion not included in this publication. Appendix C contains symbols, units, conversion factors, and atomic weights used in evaluating and compiling the thermodynamic data.

Characterizing the information content of cloud thermodynamic phase retrievals from the notional PACE OCI shortwave reflectance measurements

Science.gov (United States)

Coddington, O. M.; Vukicevic, T.; Schmidt, K. S.; Platnick, S.

2017-08-01

We rigorously quantify the probability of liquid or ice thermodynamic phase using only shortwave spectral channels specific to the National Aeronautics and Space Administration's Moderate Resolution Imaging Spectroradiometer, Visible Infrared Imaging Radiometer Suite, and the notional future Plankton, Aerosol, Cloud, ocean Ecosystem imager. The results show that two shortwave-infrared channels (2135 and 2250 nm) provide more information on cloud thermodynamic phase than either channel alone; in one case, the probability of ice phase retrieval increases from 65 to 82% by combining 2135 and 2250 nm channels. The analysis is performed with a nonlinear statistical estimation approach, the GEneralized Nonlinear Retrieval Analysis (GENRA). The GENRA technique has previously been used to quantify the retrieval of cloud optical properties from passive shortwave observations, for an assumed thermodynamic phase. Here we present the methodology needed to extend the utility of GENRA to a binary thermodynamic phase space (i.e., liquid or ice). We apply formal information content metrics to quantify our results; two of these (mutual and conditional information) have not previously been used in the field of cloud studies.

Black holes thermodynamics, information, and firewalls

CERN Document Server

Mann, Robert B

2015-01-01

This book reflects the resurgence of interest in the quantum properties of black holes, culminating most recently in controversial discussions about firewalls. On the thermodynamic side, it describes how new developments allowed the inclusion of pressure/volume terms in the first law, leading to a new understanding of black holes as chemical systems, experiencing novel phenomena such as triple points and reentrant phase transitions. On the quantum-information side, the reader learns how basic arguments undergirding quantum complementarity have been shown to be flawed; and how this suggests that a black hole may surround itself with a firewall: a violent and chaotic region of highly excited states. In this thorough and pedagogical treatment, Robert Mann traces these new developments from their roots to our present-day understanding, highlighting their relationships and the challenges they present for quantum gravity.

Stochastic and information-thermodynamic structures of population dynamics in a fluctuating environment

Science.gov (United States)

Kobayashi, Tetsuya J.; Sughiyama, Yuki

2017-07-01

Adaptation in a fluctuating environment is a process of fueling environmental information to gain fitness. Living systems have gradually developed strategies for adaptation from random and passive diversification of the phenotype to more proactive decision making, in which environmental information is sensed and exploited more actively and effectively. Understanding the fundamental relation between fitness and information is therefore crucial to clarify the limits and universal properties of adaptation. In this work, we elucidate the underlying stochastic and information-thermodynamic structure in this process, by deriving causal fluctuation relations (FRs) of fitness and information. Combined with a duality between phenotypic and environmental dynamics, the FRs reveal the limit of fitness gain, the relation of time reversibility with the achievability of the limit, and the possibility and condition for gaining excess fitness due to environmental fluctuation. The loss of fitness due to causal constraints and the limited capacity of real organisms is shown to be the difference between time-forward and time-backward path probabilities of phenotypic and environmental dynamics. Furthermore, the FRs generalize the concept of the evolutionary stable state (ESS) for fluctuating environment by giving the probability that the optimal strategy on average can be invaded by a suboptimal one owing to rare environmental fluctuation. These results clarify the information-thermodynamic structures in adaptation and evolution.

A general information theoretical proof for the second law of thermodynamics

International Nuclear Information System (INIS)

Zhang, Qiren

2008-01-01

We show that the conservation and the non-additivity of information, together with the additivity of entropy makes entropy increase in an isolated system. The collapse of the entangled quantum state offers an example of the information non-additivity. Nevertheless, the later is also true in other fields, in which the interaction information is important. Examples are classical statistical mechanics, social statistics and financial processes. The second law of thermodynamics is thus proven in its most general form. It is exactly true, not only in quantum and classical physics but also in other processes in which the information is conservative and non-additive. (author)

Customers want high-quality products at low prices, and they want them now. The message is clear: The Public compares perceived alternatives. The communication problem of the nuclear industry is the same as any other nonmonopoly provider of products or services, i.e., to show the public that nuclear electricity is superior even though nuclear electricity itself is indistinguishable from any other electricity. The following topics are discussed in this paper: (1) What the public needs in general; (2) what the public wants of information delivered; (3) the nuclear information that the public wants; (4) the ANS public information web page; and (5) wider use of issues information

Public relations as public information

Energy Technology Data Exchange (ETDEWEB)

Coninx, C.

1983-01-01

To the man in the street, the topic of nuclear energy on the one hand is a highly emotional subject incorporating dangers hard to assess. However, on the other hand, there is in most cases little inclination to concern oneself with problems of energy economy. Public relations activities therefore frequently must motivate their adresses to accept information before they can actually inform. In this connection, the informing party must appear trustworthy and avoid that a teacher : pupil relationship is created. In addition, the changes in the socio-political environment must be taken into account. Within the industries and organizations engaged in the nuclear field there is the problem that the effects and the impact of public relations work can hardly be gaged by individually, which greatly hampers quantification of the work actually done.

The risk perception and public information

The problems in the field of risk to inform the public are the difference in the risk perception by the public, between the risk realities and the image the public makes in himself, the confidence of the public towards those that give information, the readability ( and then understanding) of the information, the easiness for the public to forget the information. Solutions can be summarized by the same way: durability of information actions, information elaborated by safety authority, inhabitants associations, risk generator, elected members, supports of information clear and understandable.

The public information imperative

International Nuclear Information System (INIS)

Copeland, S.

2001-01-01

Public approval hinges not only on delivering the information the public wants but on providing tangible evidence that we are listening to public concerns. We must respond. Public acceptance depends on making real change which speaks to people's concerns. The message that the public wants to hear is that government are listening and acting on what they hear. In Canada, the nuclear regulator is increasingly active in the public arena. We held cross-country consultations as we prepared Canada's strong new Act and regulations. We have developed information vehicles such as the Radiation Index and our web site. We continue to extensively involve the public in our licensing process. All licensing hearings are open to the public. Nothing is harder to capture than public trust. This conference marks a substantial investment in learning and in our common future. We can work to build our credibility as regulators who acts on public concerns. (N.C.)

Modern thermodynamics

CERN Document Server

Ben-Naim, Arieh

2017-01-01

This textbook introduces thermodynamics with a modern approach, starting from four fundamental physical facts (the atomic nature of matter, the indistinguishability of atoms and molecules of the same species, the uncertainty principle, and the existence of equilibrium states) and analyzing the behavior of complex systems with the tools of information theory, in particular with Shannon's measure of information (or SMI), which can be defined on any probability distribution. SMI is defined and its properties and time evolution are illustrated, and it is shown that the entropy is a particular type of SMI, i.e. the SMI related to the phase-space distribution for a macroscopic system at equilibrium. The connection to SMI allows the reader to understand what entropy is and why isolated systems follow the Second Law of Thermodynamics. The Second Llaw is also formulated for other systems, not thermally isolated and even open with respect to the transfer of particles. All the fundamental aspects of thermodynamics are d...

Public information plan. Version 2

International Nuclear Information System (INIS)

1993-01-01

The Public Information Plan is intended to be used in conjunction with the U.S. Department of Energy (DOE) Uranium Mill Tailings Remedial Action (UMTRA) Project Public Participation Plan. The Public Participation Pion describes the DOE procedure for involving the public in the decision-making process related to the UMTRA Project during the stages at which public participation is required and solicited. This Public Information Plan describes the department's procedure for communicating with the public about project policies, plans, and activities. Together, these complementary plans describe the DOE public affairs program for the UMTRA Project. This project was authorized by Congress in the Uranium Mill Tailings Radiation Control Act (UMTRCA) of 1978, (Public Law (PL) 95-6041), as amended. The Act provides for a cooperative effort with affected states and Indian tribes for the cleanup of designated abandoned or inactive uranium mill tailings sites, which are located in 10 states, 9 of them west of the Mississippi River. The public has a right to know about proposed government actions and to be heard in the planning of activities that influence their lives. The UMTRA Project is unclassified and the DOE provides accurate information about policy and project activities to interested stakeholders, including the news media, in a timely way. The DOE encourages states and local governments, as well as individuals, to join actively in the decision-making process. This is intended to ensure that the resulting decisions are made with full knowledge of the public's views and that these decisions address the public's concerns to the extent possible within the law. The DOE, through the implementation of the Public Information Plan, keeps the public informed on matters such as health concerns, environmental issues, remedial action construction plans, project costs, and specific site activities

Thermodynamic description of non-Markovian information flux of nonequilibrium open quantum systems

Science.gov (United States)

Chen, Hong-Bin; Chen, Guang-Yin; Chen, Yueh-Nan

2017-12-01

One of the fundamental issues in the field of open quantum systems is the classification and quantification of non-Markovianity. In the contest of quantity-based measures of non-Markovianity, the intuition of non-Markovianity in terms of information backflow is widely discussed. However, it is not easy to characterize the information flux for a given system state and show its connection to non-Markovianity. Here, by using the concepts from thermodynamics and information theory, we discuss a potential definition of information flux of an open quantum system, valid for static environments. We present a simple protocol to show how a system attempts to share information with its environment and how it builds up system-environment correlations. We also show that the information returned from the correlations characterizes the non-Markovianity and a hierarchy of indivisibility of the system dynamics.

Thermodynamic holography

Science.gov (United States)

Wei, Bo-Bo; Jiang, Zhan-Feng; Liu, Ren-Bao

2015-01-01

The holographic principle states that the information about a volume of a system is encoded on the boundary surface of the volume. Holography appears in many branches of physics, such as optics, electromagnetism, many-body physics, quantum gravity, and string theory. Here we show that holography is also an underlying principle in thermodynamics, a most important foundation of physics. The thermodynamics of a system is fully determined by its partition function. We prove that the partition function of a finite but arbitrarily large system is an analytic function on the complex plane of physical parameters, and therefore the partition function in a region on the complex plane is uniquely determined by its values along the boundary. The thermodynamic holography has applications in studying thermodynamics of nano-scale systems (such as molecule engines, nano-generators and macromolecules) and provides a new approach to many-body physics.

Three faces of entropy for complex systems: Information, thermodynamics, and the maximum entropy principle

Science.gov (United States)

Thurner, Stefan; Corominas-Murtra, Bernat; Hanel, Rudolf

2017-09-01

There are at least three distinct ways to conceptualize entropy: entropy as an extensive thermodynamic quantity of physical systems (Clausius, Boltzmann, Gibbs), entropy as a measure for information production of ergodic sources (Shannon), and entropy as a means for statistical inference on multinomial processes (Jaynes maximum entropy principle). Even though these notions represent fundamentally different concepts, the functional form of the entropy for thermodynamic systems in equilibrium, for ergodic sources in information theory, and for independent sampling processes in statistical systems, is degenerate, H (p ) =-∑ipilogpi . For many complex systems, which are typically history-dependent, nonergodic, and nonmultinomial, this is no longer the case. Here we show that for such processes, the three entropy concepts lead to different functional forms of entropy, which we will refer to as SEXT for extensive entropy, SIT for the source information rate in information theory, and SMEP for the entropy functional that appears in the so-called maximum entropy principle, which characterizes the most likely observable distribution functions of a system. We explicitly compute these three entropy functionals for three concrete examples: for Pólya urn processes, which are simple self-reinforcing processes, for sample-space-reducing (SSR) processes, which are simple history dependent processes that are associated with power-law statistics, and finally for multinomial mixture processes.

Public information and education in Canada

International Nuclear Information System (INIS)

Macpherson, J.A.

1993-01-01

The history of providing public information on nuclear energy in Canada for more than 40 years is described. Information centers are part of all nuclear power plants and they receive many thousands of visitors each year. Until the 1970s public information programs were relatively easy. There was a lot of interest in nuclear energy, and there was little debate about it or opposition to it. But times have changed, and Canadian public information strategies and tactics have evolved to meet challenge of answering increasing public concerns. In the past 20 years Canada has gone through three phases in relationship with the public: information, communication, participation. Activities on implementation of these phases are outlined

Contact symmetries and Hamiltonian thermodynamics

International Nuclear Information System (INIS)

Bravetti, A.; Lopez-Monsalvo, C.S.; Nettel, F.

2015-01-01

It has been shown that contact geometry is the proper framework underlying classical thermodynamics and that thermodynamic fluctuations are captured by an additional metric structure related to Fisher’s Information Matrix. In this work we analyse several unaddressed aspects about the application of contact and metric geometry to thermodynamics. We consider here the Thermodynamic Phase Space and start by investigating the role of gauge transformations and Legendre symmetries for metric contact manifolds and their significance in thermodynamics. Then we present a novel mathematical characterization of first order phase transitions as equilibrium processes on the Thermodynamic Phase Space for which the Legendre symmetry is broken. Moreover, we use contact Hamiltonian dynamics to represent thermodynamic processes in a way that resembles the classical Hamiltonian formulation of conservative mechanics and we show that the relevant Hamiltonian coincides with the irreversible entropy production along thermodynamic processes. Therefore, we use such property to give a geometric definition of thermodynamically admissible fluctuations according to the Second Law of thermodynamics. Finally, we show that the length of a curve describing a thermodynamic process measures its entropy production

Introduction A key part of drug design and development is the optimization of molecular interactions between an engineered drug candidate and its binding target. Thermodynamic characterization provides information about the balance of energetic forces driving binding interactions and is essential for understanding and optimizing molecular interactions. Areas covered This review discusses the information that can be obtained from thermodynamic measurements and how this can be applied to the drug development process. Current approaches for the measurement and optimization of thermodynamic parameters are presented, specifically higher throughput and calorimetric methods. Relevant literature for this review was identified in part by bibliographic searches for the period 2004 – 2011 using the Science Citation Index and PUBMED and the keywords listed below. Expert opinion The most effective drug design and development platform comes from an integrated process utilizing all available information from structural, thermodynamic and biological studies. Continuing evolution in our understanding of the energetic basis of molecular interactions and advances in thermodynamic methods for widespread application are essential to realize the goal of thermodynamically-driven drug design. Comprehensive thermodynamic evaluation is vital early in the drug development process to speed drug development towards an optimal energetic interaction profile while retaining good pharmacological properties. Practical thermodynamic approaches, such as enthalpic optimization, thermodynamic optimization plots and the enthalpic efficiency index, have now matured to provide proven utility in design process. Improved throughput in calorimetric methods remains essential for even greater integration of thermodynamics into drug design. PMID:22458502

Coherence and measurement in quantum thermodynamics.

Science.gov (United States)

Kammerlander, P; Anders, J

2016-02-26

Thermodynamics is a highly successful macroscopic theory widely used across the natural sciences and for the construction of everyday devices, from car engines to solar cells. With thermodynamics predating quantum theory, research now aims to uncover the thermodynamic laws that govern finite size systems which may in addition host quantum effects. Recent theoretical breakthroughs include the characterisation of the efficiency of quantum thermal engines, the extension of classical non-equilibrium fluctuation theorems to the quantum regime and a new thermodynamic resource theory has led to the discovery of a set of second laws for finite size systems. These results have substantially advanced our understanding of nanoscale thermodynamics, however putting a finger on what is genuinely quantum in quantum thermodynamics has remained a challenge. Here we identify information processing tasks, the so-called projections, that can only be formulated within the framework of quantum mechanics. We show that the physical realisation of such projections can come with a non-trivial thermodynamic work only for quantum states with coherences. This contrasts with information erasure, first investigated by Landauer, for which a thermodynamic work cost applies for classical and quantum erasure alike. Repercussions on quantum work fluctuation relations and thermodynamic single-shot approaches are also discussed.

Computational methods for determining the secondary structure of RNA sequences from given alignments are currently either based on thermodynamic folding, compensatory base pair substitutions or both. However, there is currently no approach that combines both sources of information in a single...... the corresponding probability of being single stranded. Furthermore, we found that structurally conserved RNA motifs are mostly supported by folding energies. Other problems (e.g. RNA-folding kinetics) may also benefit from employing the principles of the model we introduce. Our implementation, PETfold, was tested...

Application of thermodynamics to silicate crystalline solutions

Science.gov (United States)

Saxena, S. K.

1972-01-01

A review of thermodynamic relations is presented, describing Guggenheim's regular solution models, the simple mixture, the zeroth approximation, and the quasi-chemical model. The possibilities of retrieving useful thermodynamic quantities from phase equilibrium studies are discussed. Such quantities include the activity-composition relations and the free energy of mixing in crystalline solutions. Theory and results of the study of partitioning of elements in coexisting minerals are briefly reviewed. A thermodynamic study of the intercrystalline and intracrystalline ion exchange relations gives useful information on the thermodynamic behavior of the crystalline solutions involved. Such information is necessary for the solution of most petrogenic problems and for geothermometry. Thermodynamic quantities for tungstates (CaWO4-SrWO4) are calculated.

Thermodynamically efficient solar concentrators

Winston, Roland

2012-10-01

Non-imaging Optics is the theory of thermodynamically efficient optics and as such depends more on thermodynamics than on optics. Hence in this paper a condition for the "best" design is proposed based on purely thermodynamic arguments, which we believe has profound consequences for design of thermal and even photovoltaic systems. This new way of looking at the problem of efficient concentration depends on probabilities, the ingredients of entropy and information theory while "optics" in the conventional sense recedes into the background.

Chapter 12. Public information

International Nuclear Information System (INIS)

2001-01-01

The Nuclear Regulatory Authority of the Slovak Republic (UJD) is around to serve the public. This is a regulatory institution that furnishes truthful and independent information on nuclear safety of nuclear installations, including information on management of radioactive wastes, spent fuel, nuclear materials, control and record-keeping thereof, as well as information on other fuel cycle phases. UJD seeks to provide information in an orderly, accurate and comprehensible manner in such a way that it cannot be disclaimed, as the public has the right to know the truth. In formulating information, regularity, consistency and openness are of high importance, because information presented cannot serve a controversy. UJD furnishes information independently and separately from that issued by nuclear power plant operators. As a central administration authority, UJD provides on request, within the field of its responsibility, in particular the information on safety of nuclear energy installations independently from nuclear programme implementers, allowing the public and the media to check up the data and information thereon. A significant element of the information is the demonstration that the area of nuclear energy uses in the Slovak Republic has its binding rules and the compliance therewith is controlled by the state through an independent institution - UJD. As early as in 1995 the foundations laid were at UJD for the concept for broad public information on UJD activity and on safety of nuclear installations by opening UJD Information Centre. This Centre provides communication with the public and the media, thereby contributing to fashioning among the public a favourable image of the independent state supervision over nuclear safety. The Information Centre was extended in 2000. In 2000, 76 contributions on domestic and foreign UJD activities were sent in to Slovak press agencies, dailies and electronic media. UJD is together with the SUJB the publisher of the journal

Thermodynamic framework for information in nanoscale systems with memory.

Science.gov (United States)

Arias-Gonzalez, J Ricardo

2017-11-28

Information is represented by linear strings of symbols with memory that carry errors as a result of their stochastic nature. Proofreading and edition are assumed to improve certainty although such processes may not be effective. Here, we develop a thermodynamic theory for material chains made up of nanoscopic subunits with symbolic meaning in the presence of memory. This framework is based on the characterization of single sequences of symbols constructed under a protocol and is used to derive the behavior of ensembles of sequences similarly constructed. We then analyze the role of proofreading and edition in the presence of memory finding conditions to make revision an effective process, namely, to decrease the entropy of the chain. Finally, we apply our formalism to DNA replication and RNA transcription finding that Watson and Crick hybridization energies with which nucleotides are branched to the template strand during the copying process are optimal to regulate the fidelity in proofreading. These results are important in applications of information theory to a variety of solid-state physical systems and other biomolecular processes.

Lang, Alex H; Fisher, Charles K; Mora, Thierry; Mehta, Pankaj

2014-10-03

The deep connection between thermodynamics, computation, and information is now well established both theoretically and experimentally. Here, we extend these ideas to show that thermodynamics also places fundamental constraints on statistical estimation and learning. To do so, we investigate the constraints placed by (nonequilibrium) thermodynamics on the ability of biochemical signaling networks to estimate the concentration of an external signal. We show that accuracy is limited by energy consumption, suggesting that there are fundamental thermodynamic constraints on statistical inference.

For well over 50 years, the limits to photovoltaic energy conversion have been known and codified, and have played a vital role in the push for technological breakthroughs to reach - and even attempt to surpass - those limits. This limit, known as the Shockley-Queisser detailed-balance limit, was found by using only the most basic of thermodynamic assumptions, and therefore provides an upper bound that is difficult to contest without violating the laws of thermodynamics.

Koszul information geometry and Souriau Lie group thermodynamics

Energy Technology Data Exchange (ETDEWEB)

Barbaresco, Frédéric, E-mail: frederic.barbaresco@thalesgroup.com

2015-01-13

The François Massieu 1869 idea to derive some mechanical and thermal properties of physical systems from 'Characteristic Functions', was developed by Gibbs and Duhem in thermodynamics with the concept of potentials, and introduced by Poincaré in probability. This paper deals with generalization of this Characteristic Function concept by Jean-Louis Koszul in Mathematics and by Jean-Marie Souriau in Statistical Physics. The Koszul-Vinberg Characteristic Function (KVCF) on convex cones will be presented as cornerstone of 'Information Geometry' theory, defining Koszul Entropy as Legendre transform of minus the logarithm of KVCF, and Fisher Information Metrics as hessian of these dual functions, invariant by their automorphisms. In parallel, Souriau has extended the Characteristic Function in Statistical Physics looking for other kinds of invariances through co-adjoint action of a group on its momentum space, defining physical observables like energy, heat and momentum as pure geometrical objects. In covariant Souriau model, Gibbs equilibriums states are indexed by a geometric parameter, the Geometric (Planck) Temperature, with values in the Lie algebra of the dynamical Galileo/Poincaré groups, interpreted as a space-time vector, giving to the metric tensor a null Lie derivative. Fisher Information metric appears as the opposite of the derivative of Mean 'Moment map' by geometric temperature, equivalent to a Geometric Capacity or Specific Heat. These elements has been developed by author in [10][11].

Methods for communicating technical information as public information

International Nuclear Information System (INIS)

Zara, S.A.

1987-01-01

Many challenges face the nuclear industry, especially in the waste management area. One of the biggest challenges is effective communication with the general public. Technical complexity, combined with the public's lack of knowledge and negative emotional response, complicate clear communication of radioactive waste management issues. The purpose of this session is to present and discuss methods for overcoming these obstacles and effectively transmitting technical information as public information. The methods presented encompass audio, visual, and print approaches to message transmission. To support these methods, the author also discusses techniques, based on current research, for improving the communication process

Geometric Theory of Heat from Souriau Lie Groups Thermodynamics and Koszul Hessian Geometry: Applications in Information Geometry for Exponential Families

Directory of Open Access Journals (Sweden)

Frédéric Barbaresco

2016-11-01

Full Text Available We introduce the symplectic structure of information geometry based on Souriau’s Lie group thermodynamics model, with a covariant definition of Gibbs equilibrium via invariances through co-adjoint action of a group on its moment space, defining physical observables like energy, heat, and moment as pure geometrical objects. Using geometric Planck temperature of Souriau model and symplectic cocycle notion, the Fisher metric is identified as a Souriau geometric heat capacity. The Souriau model is based on affine representation of Lie group and Lie algebra that we compare with Koszul works on G/K homogeneous space and bijective correspondence between the set of G-invariant flat connections on G/K and the set of affine representations of the Lie algebra of G. In the framework of Lie group thermodynamics, an Euler-Poincaré equation is elaborated with respect to thermodynamic variables, and a new variational principal for thermodynamics is built through an invariant Poincaré-Cartan-Souriau integral. The Souriau-Fisher metric is linked to KKS (Kostant–Kirillov–Souriau 2-form that associates a canonical homogeneous symplectic manifold to the co-adjoint orbits. We apply this model in the framework of information geometry for the action of an affine group for exponential families, and provide some illustrations of use cases for multivariate gaussian densities. Information geometry is presented in the context of the seminal work of Fréchet and his Clairaut-Legendre equation. The Souriau model of statistical physics is validated as compatible with the Balian gauge model of thermodynamics. We recall the precursor work of Casalis on affine group invariance for natural exponential families.

Thermodynamic Database for Zirconium Alloys

International Nuclear Information System (INIS)

Jerlerud Perez, Rosa

2003-05-01

For many decades zirconium alloys have been commonly used in the nuclear power industry as fuel cladding material. Besides their good corrosion resistance and acceptable mechanical properties the main reason of using these alloys is the low neutron absorption. Zirconium alloys are exposed to a very severe environment during the nuclear fission process and there is a demand for better design of this material. To meet this requirement a thermodynamic database is developed to support material designers. In this thesis some aspects about the development of a thermodynamic database for zirconium alloys are presented. A thermodynamic database represents an important facility in applying thermodynamic equilibrium calculations for a given material providing: 1) relevant information about the thermodynamic properties of the alloys e.g. enthalpies, activities, heat capacity, and 2) significant information for the manufacturing process e.g. heat treatment temperature. The basic information in the database is first the unary data, i.e. pure elements; those are taken from the compilation of the Scientific Group Thermodata Europe (SGTE) and then the binary and ternary systems. All phases present in those binary and ternary systems are described by means of the Gibbs energy dependence on composition and temperature. Many of those binary systems have been taken from published or unpublished works and others have been assessed in the present work. All the calculations have been made using Thermo C alc software and the representation of the Gibbs energy obtained by applying Calphad technique

Nuclear Regulatory Authority of the Slovak Republic (UJD) being the central state body of the Slovak Republic provides in the framework of its competence the information on safety of nuclear facilities independently of their operators. UJD enables the public and mass media to review data and information on nuclear facilities. The important point of being informed is to prove, that the area of nuclear energy use has its obligatory rules in the Slovak Republic and their observing is controlled by state through the independent institution - UJD. An establishment of UJD Information Centre as early as in 1995, the basis of conception of informing the public on UJD activities and on nuclear facilities safety was created. The Centre secures the communication with the public and mass media that helps create a positive picture on the independent regulatory authority supervising nuclear safety. Over the last year, the important attention was given to implementation of Act No 211/2000 of Coll. on Free Access to Information that entered into force on 1 January 2001. The Act established the right of the public to access to information at the disposal of state bodies, i.e. inter al ia UJD, territorial self-governing bodies and other bodies managing the public resources. The Act obliges the state bodies to make basic and standard information on their activities automatically public, in order to make the information generally available and to make public administration easier and more transparent. On 4 January 2001 UJD has issued the Regulation on Implementation of Act No 211/2000 of Coll. on Free Access to Information as amended regulating the implementation of the Act in the conditions of UJD. The information boards with the basic data on making information available pursuant to the Act were established in UJD premises in Bratislava and in Trnava.

Also, questions whenever there was a rumor or a report of a receives a growing number of E-mail letters from all over the world, on the same subjects. Increasingly, international organizations are contacted by journalists and the public, for information on incidents and accidents, in the nuclear or the radiation field. This article states that the interest on nuclear energy, isotopes and radiation is focusing in the public media on following points: the fear for an accident; the fear for radiation escaping; the belief that nuclear power plants are too expensive; the belief that electricity could be saved; the belief that nuclear wastes cannot be properly disposed; the fear for unsafe transport; the fears that the neighbors operate their plants carelessly; and fears that radiation treatment makes food or agricultural products radioactive or poisonous.

In order to inform the public on radiation and help them to understand the nature of radioactivity it is necessary to relate radiation phenomena to everyday experience and this makes the information more attractive to the media. Visual aids and analogies play an important role in any public information programme. A useful demonstration kit is described and some examples of analogies used are given. the aim of any such programme should be to stimulate interest and understanding and to place radiation hazards in perspective by comparing them with the more familiar hazards of life.

Nuclear information centre in Zbraslav and its contribution to public information

Aware of the importance of positive work with the public, the Czechoslovak Atomic Energy Commission set the Nuclear Information Centre at Zbraslav the task to develop a public information conception and to commence activities in this field. After 19 89 there appeared the need to put public information on a systematic and active basis. Following a requirement by the Czechoslovak Atomic Energy Commission, developed a 'Public Information Model Concerning the State Surveillance over Nuclear and Radiation Safety'. Actually this was a name for a conception or system of active public relations in the field of nuclear safety, of the role of the State Surveillance, and of low and intermediate level radioactive waste storage facilities. An educational programme is the heart of the entire system. Mass media are a next field through which the public is influenced. This is a very diverse field, comprising dissemination of both general information which the media (nationwide and local) make available to the wide public, and particular information for the top authorities and experts. It is envisaged that relations will be established with selected journalists who are able and willing to inform people about the safety of nuclear facilities and about nuclear wastes in an unbiased manner. Surveys and public opinion polls give unambiguous evidence that television is the most popular of mass media and is also enjoying the highest trust of the public. Cooperation with the radio was also initiated in the late 1992 and two short programmes were broadcast, dealing with a closed low and intermediate level radioactive waste repository in Central Bohemia and with the training reactor at the Faculty of Nuclear Science in Prague. The third major field of public information activities consists in printing and publishing documents.

Social, political, and economic disruptions caused by natural and human-caused public health emergencies have catalyzed public health efforts to expand the scope of biosurveillance and increase the timeliness, quality, and comprehensiveness of disease detection, alerting, response, and prediction. Unfortunately, efforts to acquire, render, and visualize the diversity of health intelligence information are hindered by its wide distribution across disparate fields, multiple levels of government, and the complex interagency environment. Achieving this new level of situation awareness within public health will require a fundamental cultural shift in methods of acquiring, analyzing, and disseminating information. The notion of information "fusion" may provide opportunities to expand data access, analysis, and information exchange to better inform public health action.

Information and interaction with the public

International Nuclear Information System (INIS)

Grlicarev, I.

2003-01-01

Full text: The public information is important for the effective implementation of countermeasures in case of a nuclear or radiation accident. The nature of public information during an accident is twofold, i.e. informing the public in the affected area and informing the general public in other (not directly affected) areas in the country. The general principles of public information, based an EU and IAEA requirements, are given, and the implementation of there principles in Slovenia is described. The Slovenian experience refers to the preparedness phase which contains measures taken to inform the public and to the response phase where the arrangements for public information have been tested in order to assure the public trust in the official information. The EU Council Directive an informing the general public focuses mainly an the population which is likely to be affected in the event of a radiological emergency. The European Commission issued the commission communication providing the information an implementation of the aforementioned directive. While the directive addresses only the population which is likely to be affected, the communication proposes a clear distinction between the regional or local population, for which there are regional or local intervention plans relating to fixed installations, and the population as a whole. In the Council Decision 87/600/Euratom stipulates that the information which should be supplied to the commission and the affected member states in case the member state decides to take the measures of a widespread nature in order to protect the general public during the radiological emergency should contain 'the measures taken, or planned, to inform the public'. The IAEA safety standards series 'Preparedness and Response for a Nuclear or Radiological Emergency' requires arrangements to provide information an the response to a nuclear or radiological emergency to the population within the urgent protective action planning zone even

We investigate the intrinsic and extrinsic curvatures of a certain hypersurface in thermodynamic geometry of a physical system and show that they contain useful thermodynamic information. For an anti-Reissner–Nordström-(A)de Sitter black hole (Phantom), the extrinsic curvature of a constant Q hypersurface has the same sign as the heat capacity around the phase transition points. The intrinsic curvature of the hypersurface can also be divergent at the critical points but has no information about the sign of the heat capacity. Our study explains the consistent relationship holding between the thermodynamic geometry of the KN-AdS black holes and those of the RN (J-zero hypersurface) and Kerr black holes (Q-zero hypersurface) ones [1]. This approach can easily be generalized to an arbitrary thermodynamic system.

Radiation risk perception and public information

Boggs-Mayes, C.J.

1988-01-01

We as Health Physicists face what, at many times, appears to be a hopeless task. The task simply stated is informing the public about the risks (or lack thereof) of radiation. Unfortunately, the public has perceived radiation risks to be much greater than they actually are. An example of this problem is shown in a paper by Arthur C. Upton. Three groups of people -- the League of Women Voters, students, and Business and Professional Club members -- were asked to rank 30 sources of risk according to their contribution to the number of deaths in the United States. Not surprisingly, they ranked nuclear power much higher and medical x-rays much lower than the actual values. In addition to the perception problem, we are faced with another hurdle: health physicists as communicators. Members of the Health Physics Society (HPS) found that the communication styles of most health physicists appear to be dissimilar to those of the general public. These authors administered the Myers-Briggs Type Indicator to the HPS Baltimore-Washington Chapter. This test, a standardized test for psychological type developed by Isabel Myers, ask questions that provide a quantitative measure of our natural preferences in four areas. Assume that you as a health physicist have the necessary skills to communicate information about radiation to the public. Health physicists do nothing with these tools. Most people involved in radiation protection do not get involved with public information activies. What I will attempt to do is heighten your interest in such activities. I will share information about public information activities in which I have been involved and give you suggestions for sources of information and materials. 2 refs., 1 tab

Applications of health information exchange information to public health practice.

Kierkegaard, Patrick; Kaushal, Rainu; Vest, Joshua R

2014-01-01

Increased information availability, timeliness, and comprehensiveness through health information exchange (HIE) can support public health practice. The potential benefits to disease monitoring, disaster response, and other public health activities served as an important justification for the US' investments in HIE. After several years of HIE implementation and funding, we sought to determine if any of the anticipated benefits of exchange participation were accruing to state and local public health practitioners participating in five different exchanges. Using qualitative interviews and template analyses, we identified public health efforts and activities that were improved by participation in HIE. HIE supported public health activities consistent with expectations in the literature. However, no single department realized all the potential benefits of HIE identified. These findings suggest ways to improve HIE usage in public health.

many leading experts in the field. During the program, the most recent developments, open questions and new ideas in stochastic thermodynamics were presented and discussed. From the talks and debates, the notion of information in stochastic thermodynamics, the fundamental properties of entropy production (rate) in non-equilibrium, the efficiency of small thermodynamic machines and the characteristics of optimal protocols for the applied (cyclic) forces were crystallizing as main themes. Surprisingly, the long-studied adiabatic piston, its peculiarities and its relation to stochastic thermodynamics were also the subject of intense discussions. The comment on the Nordita program Stochastic Thermodynamics published in this issue of Physica Scripta exploits the Jarzynski relation for determining free energy differences in the adiabatic piston. This scientific program and the contribution presented here were made possible by the financial and administrative support of The Nordic Institute for Theoretical Physics.

Public information strategies

International Nuclear Information System (INIS)

Waldahl, R.

1995-01-01

The Chernobyl accident in 1986 uncovered serious information problems in many Western countries, and started a debate on crisis communication and information strategies in relation to radiation danger in society. The information problem focuses on four main perspectives. The first is related to information as a persuasion process in which an efficient strategy would influence both the public's knowledge of radiation danger, their attitude towards it and their behaviour. The second perspective calls attention to the importance of the different elements of the information process. How important are different characteristics of the information source; the message itself, and the receiver? The third perspective concentrates on different types of information. What is this issue all about, why is the situation as it is, and how should people behave to protect themselves? The fourth perspective points to the various phases of a crisis. The information needed is obviously not the same in the period before a crisis emerges when no one knows what is going to happen, in the warning period when one knows that something may happen, and during the crisis itself.

Thermodynamic origin of nonimaging optics

Science.gov (United States)

Jiang, Lun; Winston, Roland

2016-10-01

Nonimaging optics is the theory of thermodynamically efficient optics and as such depends more on thermodynamics than on optics. Hence, in this paper, a condition for the "best" design is proposed based on purely thermodynamic arguments, which we believe has profound consequences for the designs of thermal and even photovoltaic systems. This way of looking at the problem of efficient concentration depends on probabilities, the ingredients of entropy and information theory, while "optics" in the conventional sense recedes into the background. Much of the paper is pedagogical and retrospective. Some of the development of flowline designs will be introduced at the end and the connection between the thermodynamics and flowline design will be graphically presented. We will conclude with some speculative directions of where the ideas might lead.

Structure and thermodynamics of molten salts

International Nuclear Information System (INIS)

Papatheodorou, G.N.

1983-01-01

This chapter investigates single-component molten salts and multicomponent salt mixtures. Molten salts provide an important testing ground for theories of liquids, solutions, and plasmas. Topics considered include molten salts as liquids (the pair potential, the radial distribution function, methods of characterization), single salts (structure, thermodynamic correlations), and salt mixtures (the thermodynamics of mixing; spectroscopy and structure). Neutron and X-ray scattering techniques are used to determine the structure of molten metal halide salts. The corresponding-states theory is used to obtain thermodynamic correlations on single salts. Structural information on salt mixtures is obtained by using vibrational (Raman) and electronic absorption spectroscopy. Charge-symmetrical systems and charge-unsymmetrical systems are used to examine the thermodynamics of salt mixtures

ELECTRONIC ACCOUNTING INFORMATION IN LOCAL PUBLIC ADMINISTRATION

Full Text Available Major changes in information technologies characterize the current period through which humanity creates the conditions shift from information society to the knowledge. In this context of the changing of the public administration through the implementation of ITC and the reform that lead to the new public management, our paper wants to see the development of E-governance in Romanian local public administration and the influence of the main financial indicators on e-governance elements. Countries adopt e-governance in ways that reinforce traditional bureaucratic structures, cultures and links from administration to citizens and politics, in some cases making these traditional forms more responsive. The paper studies the accounting information disclosed on the internet sites of public sector entities. The research use an empirical approach to test impact of the quality of accounting information on e-financial reporting in public sector. The research use a quantitative methodology, based on surveys and author's observations. The methods chosen in this paper are reliable for this empirical study that tries to identify at a national level the problems that could improve the financial information disclosed by the public sector. The paper aims to measure the financial performance in local public administration and the main indicators of e-governance. The main objective of the paper is to make a model that demonstrates the impact of the local public administration financial performance on the e-governance. Due to the fact that the main problem of the Romanian local public administration is the lack of performance tools that could improve the e-governance, the research wants use an empirical approach to test the impact of the financial performance on the local public administration on e-governance. The research use a quantitative methodology, based on surveys and author's observations.

Entropy and black-hole thermodynamics

International Nuclear Information System (INIS)

Wald, R.M.

1979-01-01

The concept of entropy is examined with an eye toward gaining insight into the nature of black-hole thermodynamics. Definitions of entropy are given for ordinary classical and quantum-mechanical systems which lead to plausibility arguments for the ordinary laws of thermodynamics. The treatment of entropy for a classical system is in the spirit of the information-theory viewpoint, but by explicitly incorporating the coarse-grained observable into the definition of entropy, we eliminate any nonobjective features. The definition of entropy for a quantum-mechanical system is new, but directly parallels the classical treatment. We then apply these ideas to a self-gravitating quantum system which contains a black hole. Under some assumptions: which, although nontrivial, are by no means exotic: about the nature of such a system, it is seen that the same plausibility arguments which lead to the ordinary laws of thermodynamics for ordinary systems now lead to the laws of black-hole mechanics, including the generalized second law of thermodynamics. Thus, it appears perfectly plausible that black-hole thermodynamics is nothing more than ordinary thermodynamics applied to a self-gravitating quantum system

Thermodynamics of nuclear materials

International Nuclear Information System (INIS)

1979-01-01

Full text: The science of chemical thermodynamics has substantially contributed to the understanding of the many problems encountered in nuclear and reactor technology. These problems include reaction of materials with their surroundings and chemical and physical changes of fuels. Modern reactor technology, by its very nature, has offered new fields of investigations for the scientists and engineers concerned with the design of nuclear fuel elements. Moreover, thermodynamics has been vital in predicting the behaviour of new materials for fission as well as fusion reactors. In this regard, the Symposium was organized to provide a mechanism for review and discussion of recent thermodynamic investigations of nuclear materials. The Symposium was held in the Juelich Nuclear Research Centre, at the invitation of the Government of the Federal Republic of Germany. The International Atomic Energy Agency has given much attention to the thermodynamics of nuclear materials, as is evidenced by its sponsorship of four international symposia in 1962, 1965, 1967, and 1974. The first three meetings were primarily concerned with the fundamental thermodynamics of nuclear materials; as with the 1974 meeting, this last Symposium was primarily aimed at the thermodynamic behaviour of nuclear materials in actual practice, i.e., applied thermodynamics. Many advances have been made since the 1974 meeting, both in fundamental and applied thermodynamics of nuclear materials, and this meeting provided opportunities for an exchange of new information on this topic. The Symposium dealt in part with the thermodynamic analysis of nuclear materials under conditions of high temperatures and a severe radiation environment. Several sessions were devoted to the thermodynamic studies of nuclear fuels and fission and fusion reactor materials under adverse conditions. These papers and ensuing discussions provided a better understanding of the chemical behaviour of fuels and materials under these

Within the scope of the JAEA thermodynamic database project for performance assessment of geological disposal of high-level and TRU radioactive wastes, the refinement of the thermodynamic data for the inorganic compounds and complexes of Thorium(IV), Uranium(IV), Neptunium(IV) and Plutonium(IV) was carried out. Refinement of thermodynamic data for the element was performed on a basis of the thermodynamic database for actinide published by the Nuclear Energy Agency in the Organisation for Economic Co-operation and Development (OECD/NEA). Additionally, the latest data after publication of thermodynamic data by OECD/NEA were reevaluated to determine whether the data should be included in the JAEA-TDB. (author)

Emergency public information procedures for nuclear plants

International Nuclear Information System (INIS)

Anon.

1979-01-01

As a result of the accident at Three Mile Island on March 28, 1979, increased emphasis has been placed on the public information capabilities of utility companies, and particularly their crisis public information procedures. A special industry task force was assigned to develop a generic model for a utility crisis public information plan. This report has been prepared not as a literal emergency plan for a utility, but as a generic check-off list of items and procedures that a utility should consider as a part of its own plan. Because of considerable variations in service areas, utility organization, and other factors, specific approaches may vary from utility to utility. The approaches cited here are generic suggestions that would help lead to an industrywide ability to inform the public, quickly and accurately, about non-routine events that it would consider of importance

We propose a speculative attack model in which agents receive multiple public signals. It is characterised by its focus on an informational structure, which sets free from the strict separation between public information and private information. Diverse pieces of public information can be taken into account differently by players and are likely to lead to different appreciations ex post. This process defines players’ private value. The main result is to show that equilibrium uniqueness depend...

The potential for research-based information in public health: Identifying unrecognised information needs

Directory of Open Access Journals (Sweden)

Forsetlund Louise

2001-01-01

Full Text Available Abstract Objective To explore whether there is a potential for greater use of research-based information in public health practice in a local setting. Secondly, if research-based information is relevant, to explore the extent to which this generates questioning behaviour. Design Qualitative study using focus group discussions, observation and interviews. Setting Public health practices in Norway. Participants 52 public health practitioners. Results In general, the public health practitioners had a positive attitude towards research-based information, but believed that they had few cases requiring this type of information. They did say, however, that there might be a potential for greater use. During five focus groups and six observation days we identified 28 questions/cases where it would have been appropriate to seek out research evidence according to our definition. Three of the public health practitioners identified three of these 28 cases as questions for which research-based information could have been relevant. This gap is interpreted as representing unrecognised information needs. Conclusions There is an unrealised potential in public health practice for more frequent and extensive use of research-based information. The practitioners did not appear to reflect on the need for scientific information when faced with new cases and few questions of this type were generated.

Unified geometric description of black hole thermodynamics

International Nuclear Information System (INIS)

Alvarez, Jose L.; Quevedo, Hernando; Sanchez, Alberto

2008-01-01

In the space of thermodynamic equilibrium states we introduce a Legendre invariant metric which contains all the information about the thermodynamics of black holes. The curvature of this thermodynamic metric becomes singular at those points where, according to the analysis of the heat capacities, phase transitions occur. This result is valid for the Kerr-Newman black hole and all its special cases and, therefore, provides a unified description of black hole phase transitions in terms of curvature singularities.

A thermodynamic evaluation of the Fe-Nb system

International Nuclear Information System (INIS)

Srikanth, S.; Petric, A.

1994-01-01

An optimised set of thermodynamic functions consistent with the phase diagram was derived for the Fe-Nb system from information on phase equilibria and thermodynamic data available in the literature. The thermodynamic properties of the intermediate ε (Fe 2 Nb) phase were described using the sublattice model. A Redlich-Kister equation was used to describe the excess thermodynamic functions of the liquid, bcc and fcc phases. For the μ phase, the enthalpy of formation was estimated from Miedema's model. The interaction coefficients were evaluated using an optimisation procedure employing a conjugate gradient method. The phase diagram and the thermodynamic functions calculated from the evaluated parameters are in good agreement with experimental data. (orig.)

Towards Behaviorally Informed Public Interventions

Directory of Open Access Journals (Sweden)

Karol Olejniczak

2015-06-01

Full Text Available Purpose: This article informs readers about the theoretical and practical origins of the behaviorally informed interventions (BIPI, analyzes examples of the BIPI from different policy sectors and strategies they offer for policy and regulatory design, and discusses applications and implications of BIPI for public interventions Methodology: This paper is based on a review of literature, as well as an inspection of administrative practices in OECD countries. It encompasses a systematic analysis of scientific papers fromthe SCOPUS database and a query carried out at the library of George Washington University. Findings: The traditional approach to public policy research is based on rational choice theory. It offers limited support, because by assuming perfect rationality of policy decisions, it overlooks existence of systematic errors and biases of human decision-making. The authors argue that behaviorally informed public interventions (BIPI might contribute to improving the effectiveness of a number of public measures – regulation, projects, programs, and even entire policies. Practical implications: The behavioral approach allows decision-makers to better understand the decisions and behaviors of citizens, as well as to design more effective interventions with minimum effort by adapting the existing solutions to real decision mechanisms of citizens. Originality: By combining the concepts of traditional approach with the growing behavioral approach, the authors aim to propose a new theoretical framework (BIPI to be used as a tool for policy design, delivery and evaluation.

Public opinion, public information and public implication in radioactive waste management in the European Union

International Nuclear Information System (INIS)

Taylor, D.; Webster, S.

2004-01-01

The nuclear industry in European must address the issue of the lack of Public acceptance. In particular, the public are very concerned about radioactive waste. It is clear that there is a need to better inform the public about radioactive waste and to consult them as part of the decision-making process concerning the management of these wastes. Existing and proposed new European legislation not only encourage this provision of information and involvement in the decision-making process, but actually require it. The paper examines Public opinion and European legislation in this area and reports on the latest research on societal issues in radioactive waste management carried out under the Community's Euratom Framework Programme.

Rutland, J D; Smith, A M

2010-11-01

To explore the information needs of the 'frontline' public health workforce, whether needs are being met and barriers to meeting needs. A qualitative research study using in-depth semi-structured interviews. A qualitative study, comprising eight semi-structured interviews, was conducted with one representative of each of eight categories of frontline public health professional (children's centre manager, community development worker, community midwife, district nurse, health visitor, community pharmacist, practice nurse and school nurse) to determine their public health role, information needs and barriers to meeting needs. Interviews were tape-recorded and data were analysed to identify themes for each category and common themes. Respondents expressed similar needs, some of which could be met by a dedicated library and knowledge service, given adequate funding, and some of which need input from management. The library could supply: news bulletins and up-to-date information, especially local information; targeted local websites and databases; training in literature-searching skills, basic information technology (IT) skills and critical appraisal; course and work support, with access to local library facilities; a literature search support service; signposting, with a named library contact; and access to information for patients. Management input is required to remedy basic structural barriers, including: lack of IT equipment and training; lack of time to access information; lack of funding for courses and professional development; and lack of communication of information from higher levels. Some information needs can be met by improvements and widening of access to library services, which may need increased funding. However, some barriers to meeting information needs require action elsewhere in the public health management structure. Changes need to be made in communication of public health strategy, and engagement needs to be improved between higher managerial

Williams, Glyn; Ferenczy, György G; Ulander, Johan; Keserű, György M

2017-04-01

Small is beautiful - reducing the size and complexity of chemical starting points for drug design allows better sampling of chemical space, reveals the most energetically important interactions within protein-binding sites and can lead to improvements in the physicochemical properties of the final drug. The impact of fragment-based drug discovery (FBDD) on recent drug discovery projects and our improved knowledge of the structural and thermodynamic details of ligand binding has prompted us to explore the relationships between ligand-binding thermodynamics and FBDD. Information on binding thermodynamics can give insights into the contributions to protein-ligand interactions and could therefore be used to prioritise compounds with a high degree of specificity in forming key interactions.

Enhanced Publications: Data Models and Information Systems

Directory of Open Access Journals (Sweden)

Alessia Bardi

2014-04-01

Full Text Available “Enhanced publications” are commonly intended as digital publications that consist of a mandatory narrative part (the description of the research conducted plus related “parts”, such as datasets, other publications, images, tables, workflows, devices. The state-of-the-art on information systems for enhanced publications has today reached the point where some kind of common understanding is required, in order to provide the methodology and language for scientists to compare, analyse, or simply discuss the multitude of solutions in the field. In this paper, we thoroughly examined the literature with a two-fold aim: firstly, introducing the terminology required to describe and compare structural and semantic features of existing enhanced publication data models; secondly, proposing a classification of enhanced publication information systems based on their main functional goals.

Thermodynamic properties of water solvating biomolecular surfaces

Science.gov (United States)

Heyden, Matthias

Changes in the potential energy and entropy of water molecules hydrating biomolecular interfaces play a significant role for biomolecular solubility and association. Free energy perturbation and thermodynamic integration methods allow calculations of free energy differences between two states from simulations. However, these methods are computationally demanding and do not provide insights into individual thermodynamic contributions, i.e. changes in the solvent energy or entropy. Here, we employ methods to spatially resolve distributions of hydration water thermodynamic properties in the vicinity of biomolecular surfaces. This allows direct insights into thermodynamic signatures of the hydration of hydrophobic and hydrophilic solvent accessible sites of proteins and small molecules and comparisons to ideal model surfaces. We correlate dynamic properties of hydration water molecules, i.e. translational and rotational mobility, to their thermodynamics. The latter can be used as a guide to extract thermodynamic information from experimental measurements of site-resolved water dynamics. Further, we study energy-entropy compensations of water at different hydration sites of biomolecular surfaces. This work is supported by the Cluster of Excellence RESOLV (EXC 1069) funded by the Deutsche Forschungsgemeinschaft.

Public access of environmental information. Report of an Interdepartmental Working Party on public access to information held by Pollution Control Authorities

International Nuclear Information System (INIS)

1986-01-01

The working party was set up to report to the Government ways of implementing the recommendations of the Royal Commission on Environmental Pollution that 'there should be a presumption in favour of unrestricted public access to the information which the pollution control authorities obtain or receive by virtue of their statutory powers'. Chapter 6 deals with Radioactive wastes. The present situation (eg on how the information is gathered, which department or bodies are involved etc) and the current state of the law are discussed. Licensed nuclear sites, sea disposal, inspections and defence wastes are all considered briefly. The case for improving public access to information and, recommendations on how to achieve this made, and the resource implications considered. On control of radioactive wastes there is currently no power for the responsible Government Departments to make information public. It is recommended that new legislation should confer powers to make information available, including a power to require public registers to be kept at prescribed places giving information related to certificates issued under the Radioactive Substances Act 1960.

Newman, Kristine; Dobbins, Maureen; Yost, Jennifer; Ciliska, Donna

2017-04-01

Given the many different types of professionals working in public health and their diverse roles, it is likely that their information needs, information-seeking behaviors, and problem-solving abilities differ. Although public health professionals often work in interdisciplinary teams, few studies have explored their information needs and behaviors within the context of teamwork. This study explored the relationship between Canadian public health professionals' perceptions of their problem-solving abilities and their information-seeking behaviors with a specific focus on the use of evidence in practice settings. It also explored their perceptions of collaborative information seeking and the work contexts in which they sought information. Key Canadian contacts at public health organizations helped recruit study participants through their list-servs. An electronic survey was used to gather data about (a) individual information-seeking behaviors, (b) collaborative information-seeking behaviors, (c) use of evidence in practice environments, (d) perceived problem-solving abilities, and (e) demographic characteristics. Fifty-eight public health professionals were recruited, with different roles and representing most Canadian provinces and one territory. A significant relationship was found between perceived problem-solving abilities and collaborative information-seeking behavior (r = -.44, p public health professionals take a shared, active approach to problem solving, maintain personal control, and have confidence, they are more likely collaborate with others in seeking information to complete a work task. Administrators of public health organizations should promote collaboration by implementing effective communication and information-seeking strategies, and by providing information resources and retrieval tools. Public health professionals' perceived problem-solving abilities can influence how they collaborate in seeking information. Educators in public health

Ijima, Kazunori

1998-01-01

This is a slide presentation dealing with the public information (PI) activities in Japan. At present in Japan 51 nuclear power plants are in commercial operation contributing with a capacity of about 440 G We, i.e. 1/3 of the total electricity is produced by nuclear power. An investigation conducted by Advisory Committee for Energy resulted in the following guidelines in the advancing the Nuclear Power Policy: - maintain transparency in determining policy and reflect the voice of people, making information available to the public; - promote mutual understanding between areas that produce electricity by nuclear power and those that consume electricity; - cultivate an awareness of energy issues amongst the public to encourage them to take issues regarding Japan's energy policy to heart. Concerning the current PI, the following actions are undertaken at a nationwide scale: - for all people, supplying information by mass media, internet and holding lecture meetings and panel discussions etc; - for women, advertisements in journals; - for youth, educational materials, exhibition of energy etc; - for teachers, seminars; for opinion leaders, sending newsletters on nuclear energy. In areas for planned or constructed nuclear plants the PI actions are addressed to all people, women, fishermen, farmers and opinion leaders. There are given the responses to the following three questions addressed to the public concerning the nuclear power: - do you think whether we need nuclear power plants? - do you think whether nuclear power plants are safe? - what mechanism do you think generates energy during the production of nuclear power. A discussion of the results is presented. As future objectives of PI activities the following are in view: to cultivate reliability, to aware of information about nuclear power, to promote awareness of nuclear power, to promote mutual understanding of nuclear power. In conclusion, the need is stressed to make the PI activities more effective, to find

Is there a link between selectivity and binding thermodynamics profiles?

Science.gov (United States)

Tarcsay, Ákos; Keserű, György M

2015-01-01

Thermodynamics of ligand binding is influenced by the interplay between enthalpy and entropy contributions of the binding event. The impact of these binding free energy components, however, is not limited to the primary target only. Here, we investigate the relationship between binding thermodynamics and selectivity profiles by combining publicly available data from broad off-target assay profiling and the corresponding thermodynamics measurements. Our analysis indicates that compounds binding their primary targets with higher entropy contributions tend to hit more off-targets compared with those ligands that demonstrated enthalpy-driven binding.

2018-01-01

We provide a non-equilibrium thermodynamic description of the life-cycle of a droplet based, chemically feasible, system of protocells. By coupling the protocells metabolic kinetics with its thermodynamics, we demonstrate how the system can be driven out of equilibrium to ensure protocell growth...... and replication. This coupling allows us to derive the equations of evolution and to rigorously demonstrate how growth and replication life-cycle can be understood as a non-equilibrium thermodynamic cycle. The process does not appeal to genetic information or inheritance, and is based only on non......-equilibrium physics considerations. Our non-equilibrium thermodynamic description of simple, yet realistic, processes of protocell growth and replication, represents an advance in our physical understanding of a central biological phenomenon both in connection to the origin of life and for modern biology....

Simulated pressure denaturation thermodynamics of ubiquitin.

Science.gov (United States)

Ploetz, Elizabeth A; Smith, Paul E

2017-12-01

Simulations of protein thermodynamics are generally difficult to perform and provide limited information. It is desirable to increase the degree of detail provided by simulation and thereby the potential insight into the thermodynamic properties of proteins. In this study, we outline how to analyze simulation trajectories to decompose conformation-specific, parameter free, thermodynamically defined protein volumes into residue-based contributions. The total volumes are obtained using established methods from Fluctuation Solution Theory, while the volume decomposition is new and is performed using a simple proximity method. Native and fully extended ubiquitin are used as the test conformations. Changes in the protein volumes are then followed as a function of pressure, allowing for conformation-specific protein compressibility values to also be obtained. Residue volume and compressibility values indicate significant contributions to protein denaturation thermodynamics from nonpolar and coil residues, together with a general negative compressibility exhibited by acidic residues.

Quantum Thermodynamics at Strong Coupling: Operator Thermodynamic Functions and Relations

Directory of Open Access Journals (Sweden)

Jen-Tsung Hsiang

2018-05-01

Full Text Available Identifying or constructing a fine-grained microscopic theory that will emerge under specific conditions to a known macroscopic theory is always a formidable challenge. Thermodynamics is perhaps one of the most powerful theories and best understood examples of emergence in physical sciences, which can be used for understanding the characteristics and mechanisms of emergent processes, both in terms of emergent structures and the emergent laws governing the effective or collective variables. Viewing quantum mechanics as an emergent theory requires a better understanding of all this. In this work we aim at a very modest goal, not quantum mechanics as thermodynamics, not yet, but the thermodynamics of quantum systems, or quantum thermodynamics. We will show why even with this minimal demand, there are many new issues which need be addressed and new rules formulated. The thermodynamics of small quantum many-body systems strongly coupled to a heat bath at low temperatures with non-Markovian behavior contains elements, such as quantum coherence, correlations, entanglement and fluctuations, that are not well recognized in traditional thermodynamics, built on large systems vanishingly weakly coupled to a non-dynamical reservoir. For quantum thermodynamics at strong coupling, one needs to reexamine the meaning of the thermodynamic functions, the viability of the thermodynamic relations and the validity of the thermodynamic laws anew. After a brief motivation, this paper starts with a short overview of the quantum formulation based on Gelin & Thoss and Seifert. We then provide a quantum formulation of Jarzynski’s two representations. We show how to construct the operator thermodynamic potentials, the expectation values of which provide the familiar thermodynamic variables. Constructing the operator thermodynamic functions and verifying or modifying their relations is a necessary first step in the establishment of a viable thermodynamics theory for

According to the maximum entropy principle, it has been proved that the gravitational field equations could be derived by the extrema of the total entropy for a perfect fluid, which implies that thermodynamic relations contain information as regards gravity. In this manuscript, we obtain a criterion for the thermodynamical stability of an adiabatic, self-gravitating perfect fluid system by the second variation of the total entropy. We show, for Einstein's gravity with spherical symmetry spacetime, that the criterion is consistent with that for the dynamical stability derived by Chandrasekhar and Wald. We also find that the criterion could be applied to cases without spherical symmetry, or under general perturbations. The result further establishes the connection between thermodynamics and gravity.

New directions for public information programs

International Nuclear Information System (INIS)

McCutheon, B.J.

1976-01-01

Opportunities and problems in information programming within the nuclear industry fall into three general categories: public expectations (content), getting heard (methods and media) and credibility (quality and dependability ofinformation). The difficulty of getting the message across is compounded by a negative communications climate, the lack of belief in an immediate energy shortage, competition for the public's ear and lack of interest by those not already committed. Selection of the most appropriate media should be another concern. There is also the problem of credibility of information programming by the Canadian Nuclear Association. The use of articulate, technically competent individuals in extending communications activity is recommended. Presenting the nuclear industry favourably within the broad social context is essential to prevent the industry being singled out as a symbol of growth, high technology and high risk. The nuclear debate must be perceived in terms of its increasingly political nature. The public require dependable information that will help them reach sound decisions. This is the responsibility of the nuclear industry, the utilities, appropriate government departments and educational institutions, and is not necessarily up to the politicians. (J.T.A.)

Quality Systems. A Thermodynamics-Related Interpretive Model

Directory of Open Access Journals (Sweden)

Stefano A. Lollai

2017-08-01

Full Text Available In the present paper, a Quality Systems Theory is presented. Certifiable Quality Systems are treated and interpreted in accordance with a Thermodynamics-based approach. Analysis is also conducted on the relationship between Quality Management Systems (QMSs and systems theories. A measure of entropy is proposed for QMSs, including a virtual document entropy and an entropy linked to processes and organisation. QMSs are also interpreted in light of Cybernetics, and interrelations between Information Theory and quality are also highlighted. A measure for the information content of quality documents is proposed. Such parameters can be used as adequacy indices for QMSs. From the discussed approach, suggestions for organising QMSs are also derived. Further interpretive thermodynamic-based criteria for QMSs are also proposed. The work represents the first attempt to treat quality organisational systems according to a thermodynamics-related approach. At this stage, no data are available to compare statements in the paper.

Advanced thermodynamic (exergetic) analysis

International Nuclear Information System (INIS)

Tsatsaronis, G; Morosuk, T

2012-01-01

Exergy analysis is a powerful tool for developing, evaluating and improving an energy conversion system. However, the lack of a formal procedure in using the results obtained by an exergy analysis is one of the reasons for exergy analysis not being very popular among energy practitioners. Such a formal procedure cannot be developed as long as the interactions among components of the overall system are not being taken properly into account. Splitting the exergy destruction into unavoidable and avoidable parts in a component provides a realistic measure of the potential for improving the thermodynamic efficiency of this component. Alternatively splitting the exergy destruction into endogenous and exogenous parts provides information on the interactions among system components. Distinctions between avoidable and unavoidable exergy destruction on one side and endogenous and exogenous exergy destruction on the other side allow the engineer to focus on the thermodynamic inefficiencies that can be avoided and to consider the interactions among system components. The avoidable endogenous and the avoidable exogenous exergy destruction provide the best guidance for improving the thermodynamic performance of energy conversion systems.

Extended thermodynamics

CERN Document Server

Müller, Ingo

1993-01-01

Physicists firmly believe that the differential equations of nature should be hyperbolic so as to exclude action at a distance; yet the equations of irreversible thermodynamics - those of Navier-Stokes and Fourier - are parabolic. This incompatibility between the expectation of physicists and the classical laws of thermodynamics has prompted the formulation of extended thermodynamics. After describing the motifs and early evolution of this new branch of irreversible thermodynamics, the authors apply the theory to mon-atomic gases, mixtures of gases, relativistic gases, and "gases" of phonons and photons. The discussion brings into perspective the various phenomena called second sound, such as heat propagation, propagation of shear stress and concentration, and the second sound in liquid helium. The formal mathematical structure of extended thermodynamics is exposed and the theory is shown to be fully compatible with the kinetic theory of gases. The study closes with the testing of extended thermodynamics thro...

Distributed Data Networks That Support Public Health Information Needs.

Science.gov (United States)

Tabano, David C; Cole, Elizabeth; Holve, Erin; Davidson, Arthur J

Data networks, consisting of pooled electronic health data assets from health care providers serving different patient populations, promote data sharing, population and disease monitoring, and methods to assess interventions. Better understanding of data networks, and their capacity to support public health objectives, will help foster partnerships, expand resources, and grow learning health systems. We conducted semistructured interviews with 16 key informants across the United States, identified as network stakeholders based on their respective experience in advancing health information technology and network functionality. Key informants were asked about their experience with and infrastructure used to develop data networks, including each network's utility to identify and characterize populations, usage, and sustainability. Among 11 identified data networks representing hundreds of thousands of patients, key informants described aggregated health care clinical data contributing to population health measures. Key informant interview responses were thematically grouped to illustrate how networks support public health, including (1) infrastructure and information sharing; (2) population health measures; and (3) network sustainability. Collaboration between clinical data networks and public health entities presents an opportunity to leverage infrastructure investments to support public health. Data networks can provide resources to enhance population health information and infrastructure.

Generalized laws of thermodynamics in the presence of correlations.

Bera, Manabendra N; Riera, Arnau; Lewenstein, Maciej; Winter, Andreas

2017-12-19

The laws of thermodynamics, despite their wide range of applicability, are known to break down when systems are correlated with their environments. Here we generalize thermodynamics to physical scenarios which allow presence of correlations, including those where strong correlations are present. We exploit the connection between information and physics, and introduce a consistent redefinition of heat dissipation by systematically accounting for the information flow from system to bath in terms of the conditional entropy. As a consequence, the formula for the Helmholtz free energy is accordingly modified. Such a remedy not only fixes the apparent violations of Landauer's erasure principle and the second law due to anomalous heat flows, but also leads to a generally valid reformulation of the laws of thermodynamics. In this information-theoretic approach, correlations between system and environment store work potential. Thus, in this view, the apparent anomalous heat flows are the refrigeration processes driven by such potentials.

The public production and sharing of medical information. An Australian perspective

Directory of Open Access Journals (Sweden)

Henry C.H. Ko

2010-03-01

Full Text Available There is a wealth of medical information now available to the public through various sources that are not necessarily controlled by medical or healthcare professionals. In Australia there has been a strong movement in the health consumer arena of consumer-led sharing and production of medical information and in healthcare decision-making. This has led to empowerment of the public as well as increased knowledge-sharing. There are some successful initiatives and strategies on consumer- and public-led sharing of medical information, including the formation of specialised consumer groups, independent medical information organisations, consumer peer tutoring, and email lists and consumer networking events. With well-organised public initiatives and networks, there tends to be fairly balanced information being shared. However, there needs to be caution about the use of publicly available scientific information to further the agenda of special-interest groups and lobbying groups to advance often biased and unproven opinions or for scaremongering. With the adoption of more accountability of medical research, and the increased public scrutiny of private and public research, the validity and quality of medical information reaching the public is achieving higher standards.

Toward better Alzheimer's research information sources for the public.

Science.gov (United States)

Payne, Perry W

2013-03-01

The National Plan to Address Alzheimer's Disease calls for a new relationship between researchers and members of the public. This relationship is one that provides research information to patients and allows patients to provide ideas to researchers. One way to describe it is a "bidirectional translational relationship." Despite the numerous sources of online and offline information about Alzheimer's disease, there is no information source which currently provides this interaction. This article proposes the creation an Alzheimer's research information source dedicated to monitoring Alzheimer's research literature and providing user friendly, publicly accessible summaries of data written specifically for a lay audience. This information source should contain comprehensive, updated, user friendly, publicly available, reviews of Alzheimer's research and utilize existing online multimedia/social networking tools to provide information in useful formats that help patients, caregivers, and researchers learn rapidly from one another.

Thermodynamical analysis of human thermal comfort

International Nuclear Information System (INIS)

Prek, Matjaz

2006-01-01

Traditional methods of human thermal comfort analysis are based on the first law of thermodynamics. These methods use an energy balance of the human body to determine heat transfer between the body and its environment. By contrast, the second law of thermodynamics introduces the useful concept of exergy. It enables the determination of the exergy consumption within the human body dependent on human and environmental factors. Human body exergy consumption varies with the combination of environmental (room) conditions. This process is related to human thermal comfort in connection with temperature, heat, and mass transfer. In this paper a thermodynamic analysis of human heat and mass transfer based on the 2nd law of thermodynamics in presented. It is shown that the human body's exergy consumption in relation to selected human parameters exhibits a minimal value at certain combinations of environmental parameters. The expected thermal sensation also shows that there is a correlation between exergy consumption and thermal sensation. Thus, our analysis represents an improvement in human thermal modelling and gives more information about the environmental impact on expected human thermal sensation

Neto, Abel F G; Huda, Muhammad N; Marques, Francisco C; Borges, Rosivaldo S; Neto, Antonio M J C

2017-08-01

Density functional theory was performed for thermodynamic predictions on natural gas, whose B3LYP/6-311++G(d,p), B3LYP/6-31+G(d), CBS-QB3, G3, and G4 methods were applied. Additionally, we carried out thermodynamic predictions using G3/G4 averaged. The calculations were performed for each major component of seven kinds of natural gas and to their respective air + natural gas mixtures at a thermal equilibrium between room temperature and the initial temperature of a combustion chamber during the injection stage. The following thermodynamic properties were obtained: internal energy, enthalpy, Gibbs free energy and entropy, which enabled us to investigate the thermal resistance of fuels. Also, we estimated an important parameter, namely, the specific heat ratio of each natural gas; this allowed us to compare the results with the empirical functions of these parameters, where the B3LYP/6-311++G(d,p) and G3/G4 methods showed better agreements. In addition, relevant information on the thermal and mechanic resistance of natural gases were investigated, as well as the standard thermodynamic properties for the combustion of natural gas. Thus, we show that density functional theory can be useful for predicting the thermodynamic properties of natural gas, enabling the production of more efficient compositions for the investigated fuels.

Beyond heat baths II: framework for generalized thermodynamic resource theories

Science.gov (United States)

Yunger Halpern, Nicole

2018-03-01

Thermodynamics, which describes vast systems, has been reconciled with small scales, relevant to single-molecule experiments, in resource theories. Resource theories have been used to model exchanges of energy and information. Recently, particle exchanges were modeled; and an umbrella family of thermodynamic resource theories was proposed to model diverse baths, interactions, and free energies. This paper motivates and details the family’s structure and prospective applications. How to model electrochemical, gravitational, magnetic, and other thermodynamic systems is explained. Szilárd’s engine and Landauer’s Principle are generalized, as resourcefulness is shown to be convertible not only between information and gravitational energy, but also among diverse degrees of freedom. Extensive variables are associated with quantum operators that might fail to commute, introducing extra nonclassicality into thermodynamic resource theories. An early version of this paper partially motivated the later development of noncommutative thermalization. This generalization expands the theories’ potential for modeling realistic systems with which small-scale statistical mechanics might be tested experimentally.

On the Spectral Entropy of Thermodynamic Paths for Elementary Systems

Directory of Open Access Journals (Sweden)

Daniel J. Graham

2009-12-01

Full Text Available Systems do not elect thermodynamic pathways on their own. They operate in tandem with their surroundings. Pathway selection and traversal require coordinated work and heat exchanges along with parallel tuning of the system variables. Previous research by the author (Reference [1] focused on the information expressed in thermodynamic pathways. Examined here is how spectral entropy is a by-product of information that depends intricately on the pathway structure. The spectral entropy has proven to be a valuable tool in diverse fields. This paper illustrates the contact between spectral entropy and the properties which distinguish ideal from non-ideal gases. The role of spectral entropy in the first and second laws of thermodynamics and heat → work conversions is also discussed.

Thermodynamic properties of sea air

Directory of Open Access Journals (Sweden)

R. Feistel

2010-02-01

Full Text Available Very accurate thermodynamic potential functions are available for fluid water, ice, seawater and humid air covering wide ranges of temperature and pressure conditions. They permit the consistent computation of all equilibrium properties as, for example, required for coupled atmosphere-ocean models or the analysis of observational or experimental data. With the exception of humid air, these potential functions are already formulated as international standards released by the International Association for the Properties of Water and Steam (IAPWS, and have been adopted in 2009 for oceanography by IOC/UNESCO.

In this paper, we derive a collection of formulas for important quantities expressed in terms of the thermodynamic potentials, valid for typical phase transitions and composite systems of humid air and water/ice/seawater. Particular attention is given to equilibria between seawater and humid air, referred to as "sea air" here. In a related initiative, these formulas will soon be implemented in a source-code library for easy practical use. The library is primarily aimed at oceanographic applications but will be relevant to air-sea interaction and meteorology as well.

The formulas provided are valid for any consistent set of suitable thermodynamic potential functions. Here we adopt potential functions from previous publications in which they are constructed from theoretical laws and empirical data; they are briefly summarized in the appendix. The formulas make use of the full accuracy of these thermodynamic potentials, without additional approximations or empirical coefficients. They are expressed in the temperature scale ITS-90 and the 2008 Reference-Composition Salinity Scale.

Leveraging Environmental Correlations: The Thermodynamics of Requisite Variety

Science.gov (United States)

Boyd, Alexander B.; Mandal, Dibyendu; Crutchfield, James P.

2017-06-01

Key to biological success, the requisite variety that confronts an adaptive organism is the set of detectable, accessible, and controllable states in its environment. We analyze its role in the thermodynamic functioning of information ratchets—a form of autonomous Maxwellian Demon capable of exploiting fluctuations in an external information reservoir to harvest useful work from a thermal bath. This establishes a quantitative paradigm for understanding how adaptive agents leverage structured thermal environments for their own thermodynamic benefit. General ratchets behave as memoryful communication channels, interacting with their environment sequentially and storing results to an output. The bulk of thermal ratchets analyzed to date, however, assume memoryless environments that generate input signals without temporal correlations. Employing computational mechanics and a new information-processing Second Law of Thermodynamics (IPSL) we remove these restrictions, analyzing general finite-state ratchets interacting with structured environments that generate correlated input signals. On the one hand, we demonstrate that a ratchet need not have memory to exploit an uncorrelated environment. On the other, and more appropriate to biological adaptation, we show that a ratchet must have memory to most effectively leverage structure and correlation in its environment. The lesson is that to optimally harvest work a ratchet's memory must reflect the input generator's memory. Finally, we investigate achieving the IPSL bounds on the amount of work a ratchet can extract from its environment, discovering that finite-state, optimal ratchets are unable to reach these bounds. In contrast, we show that infinite-state ratchets can go well beyond these bounds by utilizing their own infinite "negentropy". We conclude with an outline of the collective thermodynamics of information-ratchet swarms.

Thermodynamics of antibody-antigen interaction revealed by mutation analysis of antibody variable regions.

Science.gov (United States)

Akiba, Hiroki; Tsumoto, Kouhei

2015-07-01

Antibodies (immunoglobulins) bind specific molecules (i.e. antigens) with high affinity and specificity. In order to understand their mechanisms of recognition, interaction analysis based on thermodynamic and kinetic parameters, as well as structure determination is crucial. In this review, we focus on mutational analysis which gives information about the role of each amino acid residue in antibody-antigen interaction. Taking anti-hen egg lysozyme antibodies and several anti-small molecule antibodies, the energetic contribution of hot-spot and non-hot-spot residues is discussed in terms of thermodynamics. Here, thermodynamics of the contribution from aromatic, charged and hydrogen bond-forming amino acids are discussed, and their different characteristics have been elucidated. The information gives fundamental understanding of the antibody-antigen interaction. Furthermore, the consequences of antibody engineering are analysed from thermodynamic viewpoints: humanization to reduce immunogenicity and rational design to improve affinity. Amino acid residues outside hot-spots in the interface play important roles in these cases, and thus thermodynamic and kinetic parameters give much information about the antigen recognition. Thermodynamic analysis of mutant antibodies thus should lead to advanced strategies to design and select antibodies with high affinity. © The Authors 2015.

Evidence-based information needs of public health workers: a systematized review.

Science.gov (United States)

Barr-Walker, Jill

2017-01-01

This study assessed public health workers' evidence-based information needs, based on a review of the literature using a systematic search strategy. This study is based on a thesis project conducted as part of the author's master's in public health coursework and is considered a systematized review. Four databases were searched for English-language articles published between 2005 and 2015: PubMed, Web of Science, Library Literature & Information Science Index, and Library, Information Science & Technology Abstracts (LISTA). Studies were excluded if there was no primary data collection, the population in the study was not identified as public health workers, "information" was not defined according to specific criteria, or evidence-based information and public health workers were not the major focus. Studies included in the final analysis underwent data extraction, critical appraisal using CASP and STROBE checklists, and thematic analysis. Thirty-three research studies were identified in the search, including twenty-one using quantitative methods and twelve using qualitative methods. Critical appraisal revealed many potential biases, particularly in the validity of research. Thematic analysis revealed five common themes: (1) definition of information needs, (2) current information-seeking behavior and use, (3) definition of evidence-based information, (4) barriers to information needs, and (5) public health-specific issues. Recommendations are given for how librarians can increase the use of evidence-based information in public health research, practice, and policy making. Further research using rigorous methodologies and transparent reporting practices in a wider variety of settings is needed to further evaluate public health workers' information needs.

Thermodynamic efficiency of learning a rule in neural networks

Science.gov (United States)

Goldt, Sebastian; Seifert, Udo

2017-11-01

Biological systems have to build models from their sensory input data that allow them to efficiently process previously unseen inputs. Here, we study a neural network learning a binary classification rule for these inputs from examples provided by a teacher. We analyse the ability of the network to apply the rule to new inputs, that is to generalise from past experience. Using stochastic thermodynamics, we show that the thermodynamic costs of the learning process provide an upper bound on the amount of information that the network is able to learn from its teacher for both batch and online learning. This allows us to introduce a thermodynamic efficiency of learning. We analytically compute the dynamics and the efficiency of a noisy neural network performing online learning in the thermodynamic limit. In particular, we analyse three popular learning algorithms, namely Hebbian, Perceptron and AdaTron learning. Our work extends the methods of stochastic thermodynamics to a new type of learning problem and might form a suitable basis for investigating the thermodynamics of decision-making.

The American Lung Association (ALA), the nation's oldest voluntary health organization, is dedicated to the conquest of lung disease and the promotion of lung health. The objective of the ALA Radon Public Information Program is to reduce public exposure to elevated indoor radon levels through implementing grassroots-based radon public awareness campaigns by 22 local ALA groups. The program, which is funded by a grant from the US Environmental Protection Agency (EPA), was initiated in December 1989; the first phase will continue until May, 1991. Activities of local Lung Associations include distribution of free or reduced-cost radon kits; presenting programs in elementary and secondary schools; presenting information on TV news series and talk shows, and on radio Public Service Announcements and talk shows; presenting articles and feature stories in the print media; holding conferences, workshops, and displays at fairs and other exhibitions; distributing radon fact sheets through libraries and utility company mailings; and distributing videos through video chains and libraries. The local Lung Associations also serve as promoters for the EPA/Advertising Council Radon Public Service Announcement Campaign. We will highlight the activities of the groups in communicating radon health risks to the public; we will describe the results obtained and will attempt to evaluate the merits of the various approaches on the basis of the initial results

Rational extended thermodynamics

CERN Document Server

Müller, Ingo

1998-01-01

Ordinary thermodynamics provides reliable results when the thermodynamic fields are smooth, in the sense that there are no steep gradients and no rapid changes. In fluids and gases this is the domain of the equations of Navier-Stokes and Fourier. Extended thermodynamics becomes relevant for rapidly varying and strongly inhomogeneous processes. Thus the propagation of high­ frequency waves, and the shape of shock waves, and the regression of small-scale fluctuation are governed by extended thermodynamics. The field equations of ordinary thermodynamics are parabolic while extended thermodynamics is governed by hyperbolic systems. The main ingredients of extended thermodynamics are • field equations of balance type, • constitutive quantities depending on the present local state and • entropy as a concave function of the state variables. This set of assumptions leads to first order quasi-linear symmetric hyperbolic systems of field equations; it guarantees the well-posedness of initial value problems and f...

Classical and statistical thermodynamics

CERN Document Server

Rizk, Hanna A

2016-01-01

This is a text book of thermodynamics for the student who seeks thorough training in science or engineering. Systematic and thorough treatment of the fundamental principles rather than presenting the large mass of facts has been stressed. The book includes some of the historical and humanistic background of thermodynamics, but without affecting the continuity of the analytical treatment. For a clearer and more profound understanding of thermodynamics this book is highly recommended. In this respect, the author believes that a sound grounding in classical thermodynamics is an essential prerequisite for the understanding of statistical thermodynamics. Such a book comprising the two wide branches of thermodynamics is in fact unprecedented. Being a written work dealing systematically with the two main branches of thermodynamics, namely classical thermodynamics and statistical thermodynamics, together with some important indexes under only one cover, this treatise is so eminently useful.

Advance and permanent public information

1990-01-01

The accident at CHERNOBYL highlighted one of the major problems facing the nuclear industry at present and during the years to come: the need to provide information. There are two aspects to this requirement: information at a time of crisis issued when an accident such as that at CHERNOBYL takes place, but which has to be based on a procedure set up before the crisis, and advance and permanent information which prepares the ground for information at a time of crisis. The requirement for information is of particular importance in France, given the preponderance of nuclear energy in the electricity generating industry. The procedure covers the principles which were forcefully asserted by the French public authorities during the CHERNOBYL crisis, the resources strengthened or established at that time, and finally, the introduction of a policy of wider-ranging communication which is based on the idea that one can never compromise with safety

The public information programme of the IAEA is deter-mined by two basic criteria: First by the Statute of the IAEA which defines its objectives as 'to seek to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world' as well as 'to ensure as far as it is able, that assistance provided by it or at its request or under its supervision or control is not used in such a way as to further any military purpose'; second by the fact that the IAEA is an intergovernmental organization, which means that it has to fulfill request of independent, sovereign governments. In a discussion of the public infomation program of the IAEA, three main fields of activities always have to be kept in mind: Nuclear applications in agriculture, medicine, industry, hydrology, research, etc.; The use of nuclear energy for electricity generation, here mainly the aspects of safety and economics; and safeguards. From this it can be understood that the public information activities of the IAEA must have different perspectives: There are non-controversial fields for public information work, such as ost all aspects of nuclear application employing radiation and Isotopes. -- There are activities of the IAEA where the work in general is not questioned but considered absolutely necessary. -- There are finally controversial fields, where the IAEA is blamed for being too promotional. Examples are the IAEA's activities in nuclear power program planning as well as in food irradiation. In these controversial fields, it is very important to look for long-term, issue-oriented strategies to communicate good factual information in perspective

The public sector plays an important role in promoting child health information technology. Public sector support is essential in 5 main aspects of child health information technology, namely, data standards, pediatric functions in health information systems, privacy policies, research and implementation funding, and incentives for technology adoption. Some innovations in health information technology for adult populations can be transferred to or adapted for children, but there also are unique needs in the pediatric population. Development of health information technology that addresses children's needs and effective adoption of that technology are critical for US children to receive care of the highest possible quality in the future.

Korea's nuclear public information experiences-target groups and communication strategies

1996-01-01

Why public information activities in Korea are needed is first explained. There are three basic reasons; 1) to secure necessary sites for construction of large nuclear facilities; such as nuclear power plants, radwaste management facilities, and nuclear fuel-cycle related facilities 2) to maintain a friendly relationship between the local communities and the nuclear industries, 3) to promote better understanding about the nation's peaceful nuclear programs to the various target groups. Categorization of target groups and messages are reviewed. By whom the public information programs are implemented is also explained. An orchestrated effort together with the third communicators is stressed. Basic philosophy of nuclear public information programs is introduced. A high-profile information campaign and a low-profile information campaign are explained. Particular information strategies suitable to Korean situation as examined. In addition, the Korean general public perception on nuclear energy is briefly introduced. Also, some real insights of anti-nuclear movement in Korea together with the arguments are reviewed. In conclusion, the paper stresses that nuclear arguments became no more technical matters but almost socio-political issues. (author)

Asymmetrical Information and Public Failure in the Myriad Decision

Directory of Open Access Journals (Sweden)

Reginald Shareef

2014-09-01

Full Text Available The Public Value concept is a Public Management normative process that utilizes efficiency and ethics as co-equal determinants to assess organizational outcomes. As such, Public Value represents what Ghoshal calls intellectual pluralism or the utilization of normative management processes in the social sciences to challenge the intellectual absolutism of the Chicago School. One discipline where Public Value can be used to assess normative results is Legal Studies’ antitrust field. This research applies Public Value criteria in evaluating the U.S. Supreme Court’s 2013 ruling in Association for Molecular Pathology v. Myriad Genetics. The conclusions tentatively found the Court’s decision will (a create Public Value at the macro level but (b trigger public failure at the micro level for poor women because of an asymmetrical information network. This outcome fits with Stiglitz’s hypothesis concerning asymmetrical information and market failure. Further empirical research on Myriad’s policy is recommended.

The current status of fusion reactor blanket thermodynamics

International Nuclear Information System (INIS)

Veleckis, E.; Yonco, R.M.; Maroni, V.A.

1980-01-01

The available thermodynamic information is reviewed for three categories of materials that meet essential criteria for use as breeding blankets in D-T fuelled fusion reactors: liquid lithium, solid lithium alloys, and lithium-containing ceramics. The leading candidate, liquid lithium, which also has potential for use as a coolant, has been studied more extensively than have the solid alloys or ceramics. Recent studies of liquid lithium have concentrated on its sorption characteristics for hydrogen isotopes and its interaction with common impurity elements. Hydrogen isotope sorption data (P-C-T relations, activity coefficients, Sieverts' constants, plateau pressures, isotope effects, free energies of formation, phase boundaries, etc.) are presented in a tabular form that can be conveniently used to extract thermodynamic information for the α-phases of the Li-LiH, Li-LiD and Li-LiT systems and to construct complete phase diagrams. Recent solubility data for Li 3 N, Li 2 O, and Li 2 C 2 in liquid lithium are discussed with emphasis on the prospects for removing these species by cold-trapping methods. Current studies on the sorption of hydrogen in solid lithium alloys (e.g. Li-Al and Li-Pb), made using a new technique (the hydrogen titration method), have shown that these alloys should lead to smaller blanket-tritium inventories than are attainable with liquid lithium and that the P-C-T relationships for hydrogen in Li-M alloys can be estimated from lithium activity data for these alloys. There is essentially no refined thermodynamic information on the prospective ceramic blanket materials. The kinetics of tritium release from these materials is briefly discussed. Research areas are pointed out where additional thermodynamic information is needed for all three material categories. (author)

Thermodynamics of Error Correction

Directory of Open Access Journals (Sweden)

Pablo Sartori

2015-12-01

Full Text Available Information processing at the molecular scale is limited by thermal fluctuations. This can cause undesired consequences in copying information since thermal noise can lead to errors that can compromise the functionality of the copy. For example, a high error rate during DNA duplication can lead to cell death. Given the importance of accurate copying at the molecular scale, it is fundamental to understand its thermodynamic features. In this paper, we derive a universal expression for the copy error as a function of entropy production and work dissipated by the system during wrong incorporations. Its derivation is based on the second law of thermodynamics; hence, its validity is independent of the details of the molecular machinery, be it any polymerase or artificial copying device. Using this expression, we find that information can be copied in three different regimes. In two of them, work is dissipated to either increase or decrease the error. In the third regime, the protocol extracts work while correcting errors, reminiscent of a Maxwell demon. As a case study, we apply our framework to study a copy protocol assisted by kinetic proofreading, and show that it can operate in any of these three regimes. We finally show that, for any effective proofreading scheme, error reduction is limited by the chemical driving of the proofreading reaction.

Canada's Atomic Energy Control Board, considered the oldest independent nuclear regulatory body in the world, has made significant progress toward openness and visibility through public information policy initiatives and communications activities, particularly in the last five years. A number of public information projects are described, and successes as well as disappointments are outlined. The importance in terms of enhanced credibility and public confidence in the regulatory agency is stressed. In looking toward the future, the linking of communications to the operational functions and activities of the regulator is presented as a key requirement. (author)

Use of mutual information to decrease entropy: Implications for the second law of thermodynamics

International Nuclear Information System (INIS)

Lloyd, S.

1989-01-01

Several theorems on the mechanics of gathering information are proved, and the possibility of violating the second law of thermodynamics by obtaining information is discussed in light of these theorems. Maxwell's demon can lower the entropy of his surroundings by an amount equal to the difference between the maximum entropy of his recording device and its initial entropy, without generating a compensating entropy increase. A demon with human-scale recording devices can reduce the entropy of a gas by a negligible amount only, but the proof of the demon's impracticability leaves open the possibility that systems highly correlated with their environment can reduce the environment's entropy by a substantial amount without increasing entropy elsewhere. In the event that a boundary condition for the universe requires it to be in a state of low entropy when small, the correlations induced between different particle modes during the expansion phase allow the modes to behave like Maxwell's demons during the contracting phase, reducing the entropy of the universe to a low value

Japan depends on import for more than 80 percent of its total energy supply. Nuclear energy is one of the most promising alternatives to oil. It plays a significant role for energy supply in terms of reliability, economic viability and reduction of CO 2 emissions. In order to secure needed capacity, the Government concentrates its efforts on acquiring public acceptance of nuclear power as well as ensuring the safety of plants and improving plant capability and reliability. An opinion poll, done by the Japanese Government in Sep. of 1990, showed that 73.3 percent of man and 57.4 percent of women think that nuclear power is necessary to secure energy supply. Nuclear Power Engineering Corporation (NUPEC) employs various methods for information services arid, in particular, electric power generation including nuclear with an assignment from the Japanese Government. Public information activities by the Nuclear Power Engineering Corporation (NUPEC) are as follows: a) Telephone QA service to respond to public inquiries; b) Publishing the 'Nuclear Newsletter' monthly and various brochures; c) Information service by personal computer network Atomnet concerning energy in general, and operation/trouble informations of nuclear plants; d) Distribution and service of personal computers to local governments offices/museums, etc., for users ranging from children to adults to gather nuclear related information; e) Organization of female monitors 'ENE-MATES' to have lecture meetings and site tours. ENE-MATES - A Public Information Program For Women. As a 1990 opinion poll shows, women's feelings about nuclear energy differ from that of men. Women are more sensitive and anxious than men on nuclear energy issues. To improve this situation several programs for women have been planned and implemented.'ENE-MATES' program is one of these cases. It's purpose is to encourage women, centering around house wives, to have unbiased understanding of energy-related issues

Thermodynamics of phonon-modulated tunneling centers

International Nuclear Information System (INIS)

Junker, W.; Wagner, M.

1989-01-01

In recent years tunneling centers have frequently been used to explain the unusual thermodynamic properties of disordered materials; in these approaches, however, the effect of the tunneling-phonon interaction is neglected. The present study considers the archetype model of phono-assisted tunneling, which is well known from other areas of tunneling physics (quantum diffusion, etc.). It is shown that the full thermodynamic information can be rigorously extracted from a single Green function. An extended factorization procedure beyond Hartree-Fock is introduced, which is checked by sum rules as well as by exact Goldberger-Adams expansions. The phonon-modulated internal energy and specific heat are calculated for different power-law coupling setups

Thermodynamics and economics

International Nuclear Information System (INIS)

Mansson, B.A.

1990-01-01

Economics, as the social science most concerned with the use and distribution of natural resources, must start to make use of the knowledge at hand in the natural sciences about such resources. In this, thermodynamics is an essential part. In a physicists terminology, human economic activity may be described as a dissipative system which flourishes by transforming and exchanging resources, goods and services. All this involves complex networks of flows of energy and materials. This implies that thermodynamics, the physical theory of energy and materials flows, must have implications for economics. On another level, thermodynamics has been recognized as a physical theory of value, with value concepts similar to those of economic theory. This paper discusses some general aspects of the significance of non-equilibrium thermodynamics for economics. The role of exergy, probably the most important of the physical measures of value, is elucidated. Two examples of integration of thermodynamics with economic theory are reviewed. First, a simple model of a steady-state production system is sued to illustrate the effects of thermodynamic process constraints. Second, the framework of a simple macroeconomic growth model is used to illustrate how some thermodynamic limitations may be integrated in macroeconomic theory

HPLC retention thermodynamics of grape and wine tannins.

Barak, Jennifer A; Kennedy, James A

2013-05-08

The effect of grape and wine tannin structure on retention thermodynamics under reversed-phase high-performance liquid chromatography conditions on a polystyrene divinylbenzene column was investigated. On the basis of retention response to temperature, an alternative retention factor was developed to approximate the combined temperature response of the complex, unresolvable tannin mixture. This alternative retention factor was based upon relative tannin peak areas separated by an abrupt change in solvent gradient. Using this alternative retention factor, retention thermodynamics were calculated. Van't Hoff relationships of the natural log of the alternative retention factor against temperature followed Kirchoff's relationship. An inverse quadratic equation was fit to the data, and from this the thermodynamic parameters for tannin retention were calculated. All tannin fractions exhibited exothermic, spontaneous interaction, with enthalpy-entropy compensation observed. Normalizing for tannin size, distinct tannin compositional effects on thermodynamic parameters were observed. The results of this study indicate that HPLC can be valuable for measuring the thermodynamics of tannin interaction with a hydrophobic surface and provides a potentially valuable alternative to calorimetry. Furthermore, the information gathered may provide insight into understanding red wine astringency quality.

Thermodynamics of Bioreactions.

Held, Christoph; Sadowski, Gabriele

2016-06-07

Thermodynamic principles have been applied to enzyme-catalyzed reactions since the beginning of the 1930s in an attempt to understand metabolic pathways. Currently, thermodynamics is also applied to the design and analysis of biotechnological processes. The key thermodynamic quantity is the Gibbs energy of reaction, which must be negative for a reaction to occur spontaneously. However, the application of thermodynamic feasibility studies sometimes yields positive Gibbs energies of reaction even for reactions that are known to occur spontaneously, such as glycolysis. This article reviews the application of thermodynamics in enzyme-catalyzed reactions. It summarizes the basic thermodynamic relationships used for describing the Gibbs energy of reaction and also refers to the nonuniform application of these relationships in the literature. The review summarizes state-of-the-art approaches that describe the influence of temperature, pH, electrolytes, solvents, and concentrations of reacting agents on the Gibbs energy of reaction and, therefore, on the feasibility and yield of biological reactions.

Thermodynamic forces in coarse-grained simulations

Science.gov (United States)

Noid, William

Atomically detailed molecular dynamics simulations have profoundly advanced our understanding of the structure and interactions in soft condensed phases. Nevertheless, despite dramatic advances in the methodology and resources for simulating atomically detailed models, low-resolution coarse-grained (CG) models play a central and rapidly growing role in science. CG models not only empower researchers to investigate phenomena beyond the scope of atomically detailed simulations, but also to precisely tailor models for specific phenomena. However, in contrast to atomically detailed simulations, which evolve on a potential energy surface, CG simulations should evolve on a free energy surface. Therefore, the forces in CG models should reflect the thermodynamic information that has been eliminated from the CG configuration space. As a consequence of these thermodynamic forces, CG models often demonstrate limited transferability and, moreover, rarely provide an accurate description of both structural and thermodynamic properties. In this talk, I will present a framework that clarifies the origin and impact of these thermodynamic forces. Additionally, I will present computational methods for quantifying these forces and incorporating their effects into CG MD simulations. As time allows, I will demonstrate applications of this framework for liquids, polymers, and interfaces. We gratefully acknowledge the support of the National Science Foundation via CHE 1565631.

Role of market information in gaining public acceptance

International Nuclear Information System (INIS)

Berman, A.B.

1992-01-01

The nuclear energy industry challenge to gain acceptance for its next generation of nuclear power plants is immense. If not the majority, then a vocal minority, has doubts about the technology, its need, or those who implement it. Perceptions about the nuclear industry are complex. These are due to the difficulty in understanding the technology itself, the trade-offs of benefits against repercussions, and well-publicized plant problems. The industry requires a continual flow of actionable and comprehensive market information as input for decision making. The cost of implementing misdirected strategies is high. If not sensitive to public needs, the cost is opposition to nuclear development based on faulty or unsubstantiated reasoning. This paper addresses the required market information flow. It is suggested that a market information system is necessary for timely and usable information to ensure understanding of industry developmental efforts

Design of thermodynamic experiments and analyses of thermodynamic relationships

International Nuclear Information System (INIS)

Oezer Arnas, A.

2009-01-01

In teaching of thermodynamics, a certain textbook is followed internationally whatever language it is written in. However, although some do a very good job, most are not correct and precise and furthermore NONE discuss at all the need for and importance of designing thermodynamic experiments although experimentation in engineering is considered to be the back bone of analyses, not pursued much these days, or numerical studies, so very predominant these days. Here some thermodynamic experiments along with physical interpretation of phenomena through simple mathematics will be discussed that are straightforward, meaningful and which can be performed by any undergraduate/graduate student. Another important topic for discussion is the fact that the thermodynamic state principle demands uniqueness of results. It has been found in literature that this fact is not well understood by those who attempt to apply it loosely and end up with questionable results. Thermodynamics is the fundamental science that clarifies all these issues if well understood, applied and interpreted. The attempt of this paper is to clarify these situations and offer alternative methods for analyses. (author)

Is thermodynamic irreversibility a consequence of the expansion of the Universe?

Science.gov (United States)

Osváth, Szabolcs

2018-02-01

This paper explains thermodynamic irreversibility by applying the expansion of the Universe to thermodynamic systems. The effect of metric expansion is immeasurably small on shorter scales than intergalactic distances. Multi-particle systems, however, are chaotic, and amplify any small disturbance exponentially. Metric expansion gives rise to time-asymmetric behaviour in thermodynamic systems in a short time (few nanoseconds in air, few ten picoseconds in water). In contrast to existing publications, this paper explains without any additional assumptions the rise of thermodynamic irreversibility from the underlying reversible mechanics of particles. Calculations for the special case which assumes FLRW metric, slow motions (v ≪ c) and approximates space locally by Euclidean space show that metric expansion causes entropy increase in isolated systems. The rise of time-asymmetry, however, is not affected by these assumptions. Any influence of the expansion of the Universe on the local metric causes a coupling between local mechanics and evolution of the Universe.

The thermodynamic properties of benzothiazole and benzoxazole

1991-08-01

This research program, funded by the Department of Energy, Office of Fossil Energy, Advanced Extraction and Process Technology, provides accurate experimental thermochemical and thermophysical properties for key organic diheteroatom-containing compounds present in heavy petroleum feedstocks, and applies the experimental information to thermodynamic analyses of key hydrodesulfurization, hydrodenitrogenation, and hydrodeoxygenation reaction networks. Thermodynamic analyses, based on accurate information, provide insights for the design of cost-effective methods of heteroatom removal. The results reported here, and in a companion report to be completed, will point the way to the development of new methods of heteroatom removal from heavy petroleum. Measurements leading to the calculation of the ideal-gas thermodynamic properties are reported for benzothiazole and benzoxazole. Experimental methods included combustion calorimetry, adiabatic heat-capacity calorimetry, comparative ebulliometry, inclinded-piston gauge manometry, and differential-scanning calorimetry (d.s.c). Critical property estimates are made for both compounds. Entropies, enthalpies, and Gibbs energies of formation were derived for the ideal gas for both compounds for selected temperatures between 280 K and near 650 K. The Gibbs energies of formation will be used in a subsequent report in thermodynamic calculations to study the reaction pathways for the removal of the heteratoms by hydrogenolysis. The results obtained in this research are compared with values present in the literature. The failure of a previous adiabatic heat capacity study to see the phase transition in benzothiazole is noted. Literature vibrational frequency assignments were used to calculate ideal gas entropies in the temperature range reported here for both compounds. Resulting large deviations show the need for a revision of those assignments.

A large number of legacy datasets are contained in geoscience literature published between 1930 and 1980 and not expressed external to the publication text in digitized formats. Extracting, organizing, and reusing these "dark" datasets is highly valuable for many within the Earth and planetary science community. As a part of the Deep Carbon Observatory (DCO) data legacy missions, the DCO Data Science Team and Extreme Physics and Chemistry community identified thermodynamic datasets related to carbon, or more specifically datasets about the enthalpy and entropy of chemicals, as a proof of principle analysis. The data science team endeavored to develop a semi-automatic workflow, which includes identifying relevant publications, extracting contained datasets using OCR methods, collaborative reviewing, and registering the datasets via the DCO Data Portal where the 'Linked Data' feature of the data portal provides a mechanism for connecting rescued datasets beyond their individual data sources, to research domains, DCO Communities, and more, making data discovery and retrieval more effective.To date, the team has successfully rescued, deposited and registered additional datasets from publications with thermodynamic sources. These datasets contain 3 main types of data: (1) heat content or enthalpy data determined for a given compound as a function of temperature using high-temperature calorimetry, (2) heat content or enthalpy data determined for a given compound as a function of temperature using adiabatic calorimetry, and (3) direct determination of heat capacity of a compound as a function of temperature using differential scanning calorimetry. The data science team integrated these datasets and delivered a spectrum of data analytics including visualizations, which will lead to a comprehensive characterization of the thermodynamics of carbon and carbon-related materials.

A New Thermodynamics from Nuclei to Stars

Directory of Open Access Journals (Sweden)

Dieter H.E. Gross

2004-03-01

Full Text Available Abstract: Equilibrium statistics of Hamiltonian systems is correctly described by the microcanonical ensemble. Classically this is the manifold of all points in the N-body phase space with the given total energy. Due to Boltzmann's principle, eS=tr(δ(E-H, its geometrical size is related to the entropy S(E,N,.... This definition does not invoke any information theory, no thermodynamic limit, no extensivity, and no homogeneity assumption, as are needed in conventional (canonical thermo-statistics. Therefore, it describes the equilibrium statistics of extensive as well of non-extensive systems. Due to this fact it is the fundamental definition of any classical equilibrium statistics. It can address nuclei and astrophysical objects as well. All kind of phase transitions can be distinguished sharply and uniquely for even small systems. It is further shown that the second law is a natural consequence of the statistical nature of thermodynamics which describes all systems with the same -- redundant -- set of few control parameters simultaneously. It has nothing to do with the thermodynamic limit. It even works in systems which are by far than any thermodynamic "limit".

The Public Information Compliance and Dissemination Among Urban and Rural Society

Directory of Open Access Journals (Sweden)

Vience Mutiara Rumata

2017-07-01

Full Text Available In the information era, the abundance of information and access due to the internet has brought unprecedented challenges to the Ministry of Communication and Information Technology as public communication administrator. The internet penetration in Indonesia continues to grow annually. Nevertheless, does it reflect that the internet is the main source of public information? This research explores the public information compliance and dissemination among urban and rural societies. The research method is quantitative with the primary data is a survey at 12 provinces in Indonesia which were selected through probability sampling technique. It is a national survey with 2% margin of error estimation. The sample size reaches 2,500 respondents. The data analysis method is statistic-descriptive as the results as follows: the perception of public information particularly the government policies access is sufficiently well, although the popularity of the MCIT, as well as its local office's official media, is lower than television. The interpersonal relations and social environment influence someone to get and disseminate the information. The face to face communication is a prominent channel to disseminate information both in the urban and rural areas.

Chemical thermodynamics of iron - Part 1 - Chemical thermodynamics volume 13a

International Nuclear Information System (INIS)

Lemire, Robert J.; Berner, Urs; Musikas, Claude; Palmer, Donald A.; Taylor, Peter; Tochiyama, Osamu; Perrone, Jane

2013-01-01

Volume 13a of the 'Chemical Thermodynamics' (TDB) series, is the first of two volumes describing the selection of chemical thermodynamic data for species of iron. Because of the voluminous information in the literature, it has been more efficient to prepare the review in two (unequal) parts. This larger first part contains assessments of data for the metal, simple ions, aqueous hydroxido, chlorido, sulfido, sulfato and carbonato complexes, and for solid oxides and hydroxides, halides, sulfates, carbonates and simple silicates. The second part will provide assessments of data for other aqueous halido species, sulfide solids, and solid and solution species with nitrate, phosphate and arsenate, as well as some aspects of solid solutions in iron-oxide and iron-sulfide systems. The database system developed at the OECD/NEA Data Bank ensures consistency not only within the recommended data sets of iron, but also among all the data sets published in the series. This volume will be of particular interest to scientists carrying out performance assessments of deep geological disposal sites for radioactive waste

Glaenzel, W.; Chi, P.S.; Gumpenberger, C.; Gorraiz, J.

2016-07-01

Journal citation measures, if properly used, provide important information on the author’s publication strategy. In this explorative study, which is part of a larger project, we attempt to shed light on to what extent publication strategies are adequately reflected by the impact generated in the respective scientific community in the context of academic research assessment at micro level.In this paper we present three cases based on the research output of researchers active in three different fields: chemistry, medicine and economics. In each individual case, the lists of journals, in which the author in question has published along with the journals in the reference lists and those where the citing papers have been published, are analysed according to two aspects, the congruence of the three resulting lists and the overlap by journal quartiles based on field-normalised impact. Similarity measures are then introduced at both levels.The results reveal important aspects of the authors’ publication strategy and their position in the information flow enabling the identification of different scenarios, which are discussed in detail in order to be correctly applied for bibliometric individual assessment.

Full text: Good safety culture is strongly related to transparent and timely information. Experience has shown that radiation and nuclear safety are under continuous surveillance by the public. The provision of open and authentic information to the public is a fundamental policy of the SNSA. The SNSA endeavors to provide substantial and reliable information to the interested institutions, mass media and to the citizens through press conferences, public statements, media discussions, and active participation in domestic and international meetings, symposia and congresses, through publications, the Internet and direct contacts with the interested public. The SNSA regularly provides information on nuclear safety to the Government, the National Assembly and the citizens of the Republic of Slovenia. The Annual Report on Nuclear and Radiation Safety is published in Poroeevalec (Reporter) - the publication of the National Assembly - in autumn, and is available in public libraries throughout Slovenia. Annual Report is available also on the Internet (http://www.sigov.si/ursjv/uvod.html) in Slovene and English. Access to data of the Central Radiation Early Warning System of Slovenia (CROSS), recording the real time (at half-hour intervals) gamma dose rate levels, is also available through Internet. The report in English is sent every year to Slovenian embassies world-wide, to certain foreign embassies in Slovenia and to other organizations participating in the activities in the nuclear and radiological field. Reports on the SNSA activities are also published in the bulletin Okolje in prostor (Environment and Spatial Planning), published by the Ministry of Environment and Spatial Planning. The SNSA regularly contributes articles on courses, seminars and symposia attended at home and abroad. The articles are intended to give basic information on training and the names of contact persons to provide additional information on certain topics to those interested. More than half of

Sticker Shock: How Information Affects Citizen Support for Public School Funding.

Science.gov (United States)

Schueler, Beth E; West, Martin R

2016-01-01

This study examines the role of information in shaping public opinion in the context of support for education spending. While there is broad public support for increasing government funding for public schools, Americans tend to underestimate what is currently spent. We embed a series of experiments in a nationally representative survey administered in 2012 ( n = 2,993) to examine whether informing citizens about current levels of education spending alters public opinion about whether funding should increase. Providing information on per-pupil spending in a respondent's local school district reduces the probability that he or she will express support for increasing spending by 22 percentage points on average. Informing respondents about state-average teacher salaries similarly depresses support for salary increases. These effects are larger among respondents who underestimate per-pupil spending and teacher salaries by a greater amount, consistent with the idea that the observed changes in opinion are driven, at least in part, by informational effects, as opposed to priming alone.

The thermodynamic cost of quantum operations

International Nuclear Information System (INIS)

Bedingham, D J; Maroney, O J E

2016-01-01

The amount of heat generated by computers is rapidly becoming one of the main problems for developing new generations of information technology. The thermodynamics of computation sets the ultimate physical bounds on heat generation. A lower bound is set by the Landauer limit, at which computation becomes thermodynamically reversible. For classical computation there is no physical principle which prevents this limit being reached, and approaches to it are already being experimentally tested. In this paper we show that for quantum computation with a set of signal states satisfying given conditions, there is an unavoidable excess heat generation that renders it inherently thermodynamically irreversible. The Landauer limit cannot, in general, be reached by quantum computers. We show the existence of a lower bound to the heat generated by quantum computing that exceeds that given by the Landauer limit, give the special conditions where this excess cost may be avoided, and provide a protocol for achieving the limiting heat cost when these conditions are met. We also show how classical computing falls within the special conditions. (paper)

Fluctuating Thermodynamics for Biological Processes

Science.gov (United States)

Ham, Sihyun

Because biomolecular processes are largely under thermodynamic control, dynamic extension of thermodynamics is necessary to uncover the mechanisms and driving factors of fluctuating processes. The fluctuating thermodynamics technology presented in this talk offers a practical means for the thermodynamic characterization of conformational dynamics in biomolecules. The use of fluctuating thermodynamics has the potential to provide a comprehensive picture of fluctuating phenomena in diverse biological processes. Through the application of fluctuating thermodynamics, we provide a thermodynamic perspective on the misfolding and aggregation of the various proteins associated with human diseases. In this talk, I will present the detailed concepts and applications of the fluctuating thermodynamics technology for elucidating biological processes.

High-temperature experimental and thermodynamic modelling research on the pyrometallurgical processing of copper

Science.gov (United States)

Hidayat, Taufiq; Shishin, Denis; Decterov, Sergei A.; Hayes, Peter C.; Jak, Evgueni

2017-01-01

Uncertainty in the metal price and competition between producers mean that the daily operation of a smelter needs to target high recovery of valuable elements at low operating cost. Options for the improvement of the plant operation can be examined and decision making can be informed based on accurate information from laboratory experimentation coupled with predictions using advanced thermodynamic models. Integrated high-temperature experimental and thermodynamic modelling research on phase equilibria and thermodynamics of copper-containing systems have been undertaken at the Pyrometallurgy Innovation Centre (PYROSEARCH). The experimental phase equilibria studies involve high-temperature equilibration, rapid quenching and direct measurement of phase compositions using electron probe X-ray microanalysis (EPMA). The thermodynamic modelling deals with the development of accurate thermodynamic database built through critical evaluation of experimental data, selection of solution models, and optimization of models parameters. The database covers the Al-Ca-Cu-Fe-Mg-O-S-Si chemical system. The gas, slag, matte, liquid and solid metal phases, spinel solid solution as well as numerous solid oxide and sulphide phases are included. The database works within the FactSage software environment. Examples of phase equilibria data and thermodynamic models of selected systems, as well as possible implementation of the research outcomes to selected copper making processes are presented.

Public judgments of information in a diazepam patient package insert.

Science.gov (United States)

Fisher, S; Mansbridge, B; Lankford, D A

1982-06-01

As part of a larger study of the effects of giving patients written take-home information with prescription medications, a "patient package insert" (PPI) for diazepam was prepared based on content determined by "experts." This report compares the experts' judgments of what information should be included with judgments obtained from the public. Information judged to be most important for inclusion in a PPI was identified by having subjects sort cards containing facts about diazepam. Subjects who had previously used diazepam were no different in their judgments than inexperienced subjects. In general, there was a high degree of concordance between public and expert judgments and also a remarkably strong consensus across very different demographic samples. In those few instances of disagreement, the public attached even greater importance to warnings and "bad news" about diazepam than to information providing reassurances, benign general education, and "good news." To what extent patients would effectively use this information--whether conveyed by PPIs or alternative educational routes--must await empirical evaluation.

Public information about clinical trials and research.

Plétan, Yannick; Zannad, Faïez; Jaillon, Patrice

2003-01-01

Be it to restore the confused image of clinical research in relation to the lay public, or to develop new ways of accruing healthy volunteers or patients for clinical trials, there is a need to draft some guidance on how best to provide information on research. Although the French legal and regulatory armamentarium in this area is essentially liberal, there is currently little-justified reluctance among study sponsors to advertise publicly. A group of academic and pharmaceutical industry researchers, assembled for a workshop, together with regulators, journalists, representatives from ethics committees, social security, patient and health consumer groups and other French institutional bodies, has suggested the following series of recommendations: there is no need for additional legal or regulatory constraints; sponsors should be aware of and make use of direct public information on trials; a 'good practice charter' on public communication about clinical trials should be developed; all professionals should be involved in this communication platform; communication in the patient's immediate vicinity should be preferred (primary-care physician, local press); clinical databases and websites accessible to professionals, but also to patients and non-professionals, should be developed; genuine instruction on clinical trials for physicians and health professionals unfamiliar with such trials should be developed and disseminated; media groups should receive at least some training in the fundamentals of clinical research.

The mutual co-implication of thermodynamics' first and second laws

OpenAIRE

Plastino, A.; Curado, E. M. F.

2004-01-01

In classical phenomenological thermodynamics the first and second laws can be regarded as independent statements. Statistical mechanics provides a microscopic substratum that explains thermodynamics in probabilistic terms via a microstate probability distribution ${p_i}$. We study here a hitherto unexplored microscopic connection between the two laws. Given an information measure (or entropic form), each of the two laws implies the other through the process $p_i \\to p_i+dp_i$.

Statistical physics and thermodynamics an introduction to key concepts

CERN Document Server

Rau, Jochen

2017-01-01

Statistical physics and thermodynamics describe the behaviour of systems on the macroscopic scale. Their methods are applicable to a wide range of phenomena: from refrigerators to the interior of stars, from chemical reactions to magnetism. Indeed, of all physical laws, the laws of thermodynamics are perhaps the most universal. This text provides a concise yet thorough introduction to the key concepts which underlie statistical physics and thermodynamics. It begins with a review of classical probability theory and quantum theory, as well as a careful discussion of the notions of information and entropy, prior to embarking on the development of statistical physics proper. The crucial steps leading from the microscopic to the macroscopic domain are rendered transparent. In particular, the laws of thermodynamics are shown to emerge as natural consequences of the statistical framework. While the emphasis is on clarifying the basic concepts, the text also contains many applications and classroom-tested exercises,...

Atmospheric thermodynamics

CERN Document Server

Iribarne, J V

1973-01-01

The thermodynamics of the atmosphere is the subject of several chapters in most textbooks on dynamic meteorology, but there is no work in English to give the subject a specific and more extensive treatment. In writing the present textbook, we have tried to fill this rather remarkable gap in the literature related to atmospheric sciences. Our aim has been to provide students of meteorology with a book that can playa role similar to the textbooks on chemical thermodynamics for the chemists. This implies a previous knowledge of general thermodynamics, such as students acquire in general physics courses; therefore, although the basic principles are reviewed (in the first four chapters), they are only briefly discussed, and emphasis is laid on those topics that will be useful in later chapters, through their application to atmospheric problems. No attempt has been made to introduce the thermodynamics of irreversible processes; on the other hand, consideration of heterogeneous and open homogeneous systems permits a...

The Effect of Publicized Quality Information on Home Health Agency Choice.

Science.gov (United States)

Jung, Jeah Kyoungrae; Wu, Bingxiao; Kim, Hyunjee; Polsky, Daniel

2016-12-01

We examine consumers' use of publicized quality information in Medicare home health care markets, where consumer cost sharing and travel costs are absent. We report two findings. First, agencies with high quality scores are more likely to be preferred by consumers after the introduction of a public reporting program than before. Second, consumers' use of publicized quality information differs by patient group. Community-based patients have slightly larger responses to public reporting than hospital-discharged patients. Patients with functional limitations at the start of their care, at least among hospital-discharged patients, have a larger response to the reported functional outcome measure than those without functional limitations. In all cases of significant marginal effects, magnitudes are small. We conclude that the current public reporting approach is unlikely to have critical impacts on home health agency choice. Identifying and releasing quality information that is meaningful to consumers may help increase consumers' use of public reports. © The Author(s) 2015.

Public information activities of the IAEA

Meyer, Hand-Friedrich

1998-01-01

Since the accident at Three Mile Island in 1979 and increasingly since the Chernobyl accident 1986, the Division of Public Information (DPI) of the IAEA has become a contact point for journalists on all questions related to the nuclear energy and nuclear applications. The IAEA receives a continuously growing number of hits on its Internet Homepage. This is followed by an increasing number of E-mail letters from all over the world. The three main fields of general information activities of the IAEA's DPI are: 1 - the verification system of IAEA in the framework of international treaties concerning non-proliferation of nuclear weapons; 2 - the IAEA's work for safe operation of nuclear installations and its many services to improve the safe application of radiation and isotopes as well as safe operation of nuclear power plants. Questions on illicit trafficking and dangers of wrongly applied radiation sources play an important factor in our public information work in the field of nuclear safety; 3 - the IAEA's activities in the transfer of technology and the application of radiation and isotopes in agriculture, health, industry, hydrology and research. In addition to the new ways of providing information on the IAEA there is still the long established means of contact through periodicals like 'IAEA Bulletin' and 'IAEA Newsbriefs' or general information films like, for instance, 'The International Atom', 'The Nuclear Age', 'How a nuclear power plant works', 'Nuclear Energy and the Environment', 'The Safe Transport of Radioactive Material', 'The International Chernobyl Project', 'Mission Iraq' and others. Besides, there are aspects on longer lasting perspectives which should be considered: - physics teaching at schools; - information on nuclear fission, nuclear power, radiation and isotopes in a science museum in the capital; an information center at nuclear research facilities in the country. Nuclear has many advantages but it is difficult these days to convince normal

Science Center Public Forums: Engaging Lay-Publics in Resilience Deliberations Through Informal Science Education

Science.gov (United States)

Sittenfeld, D.; Choi, F.; Farooque, M.; Helmuth, B.

2017-12-01

Because climate hazards present a range of potential impacts and considerations for different kinds of stakeholders, community responses to increase resilience are best considered through the inclusion of diverse, informed perspectives. The Science Center Public Forums project has created multifaceted modules to engage diverse publics in substantive deliberations around four hazards: heat waves, drought, extreme precipitation, and sea level rise. Using a suite of background materials including visualization and narrative components, each of these daylong dialogues engage varied groups of lay-participants at eight US science centers in learning about hazard vulnerabilities and tradeoffs of proposed strategies for building resilience. Participants listen to and consider the priorities and perspectives of fellow residents and stakeholders, and work together to formulate detailed resilience plans reflecting both current science and informed public values. Deliverables for the project include visualizations of hazard vulnerabilities and strategies through immersive planetarium graphics and Google Earth, stakeholder perspective narratives, and detailed background materials for each project hazard. This session will: communicate the process for developing the hazard modules with input from subject matter experts, outline the process for iterative revisions based upon findings from formative focus groups, share results generated by participants of the project's first two pilot forums, and describe plans for broader implementation. These activities and outcomes could help to increase the capacity of informal science education institutions as trusted conveners for informed community dialogue by educating residents about vulnerabilities and engaging them in critical thinking about potential policy responses to critical climate hazards while sharing usable public values and priorities with civic planners.

Black hole thermodynamics based on unitary evolutions

International Nuclear Information System (INIS)

Feng, Yu-Lei; Chen, Yi-Xin

2015-01-01

In this paper, we try to construct black hole thermodynamics based on the fact that the formation and evaporation of a black hole can be described by quantum unitary evolutions. First, we show that the Bekenstein–Hawking entropy S BH may not be a Boltzmann or thermal entropy. To confirm this statement, we show that the original black hole's ‘first law’ may not simply be treated as the first law of thermodynamics formally, due to some missing metric perturbations caused by matter. Then, by including those (quantum) metric perturbations, we show that the black hole formation and evaporation can be described effectively in a unitary manner, through a quantum channel between the exterior and interior of the event horizon. In this way, the paradoxes of information loss and firewall can be resolved effectively. Finally, we show that black hole thermodynamics can be constructed in an ordinary way, by constructing statistical mechanics. (paper)

A thermodynamic description of quarks at the subquark level

International Nuclear Information System (INIS)

Fitzpatrick, G.L.

1985-01-01

A thermodynamic basis for the description of quarks at the subquark level is proposed. It is suggested that subquarks are ultrarelativistic objects confined to the quark radius R. Thus they experience accelerations of the order a≅c/sup 2//R. But this means that information excluding horizons (iota) comparable to quark radii R, namely iota≅c/sup 2//a≅R, are present. Such horizons force us to describe quarks, at the subquark level, via thermodynamics. This thermodynamic description must involve unconventional negative energy Rindler vacua, rather than the conventional zero energy Minkowski vacuum. In an average thermodynamic sense, these Rindler vacua cancel excess kinetic energy of the subquarks, thereby removing an objection to theories involving subquarks. In any such theory it is necessary to assign an Unruh temperature T, where kT≅(h/2πc)a≅(hc/2πR), to the subquark matter. The author argues that T must be the temperature of the early universe phase transition (probably first order) at which quarks condensed into hadrons. Thus quarks have a temperature T independent of hadron mass. He shows how quark properties may be derived in the foregoing thermodynamic context

Informing the educators: one of the keys to public acceptance

International Nuclear Information System (INIS)

Mattox, G.C.; Reynolds, A.B.; Brenizer, J.S.

1986-01-01

One of the most difficult barriers to overcome in the task of gaining greater public acceptance of nuclear power is the widespread lack of correct information about the true risks and benefits of nuclear energy. The news media are the most prevalent sources of information for the public but they are highly constrained by the limits of space, time, and reader/viewer interest span in being able to cover this complex subject with any degree of completeness, much less with any degree of accuracy. Another source of information for the general public is the educational system, and while it also has its limitations, they are somewhat different from those faced by the media, and the educational system is generally considered to be a more credible information source than the media. This paper report on three programs undertaken in 1985 and 1986 by the Virginia Section of the American Nuclear Society (ANS) in conjunction with the University of Virginia (UVA), the Virginia State Department of Education, and various nuclear industry participants. Each program had its unique features, successes, an failures. All-in-all, these programs have been reported as being quite successful in helping to reach the public through informing the educators

Identifying functional thermodynamics in autonomous Maxwellian ratchets

Science.gov (United States)

Boyd, Alexander B.; Mandal, Dibyendu; Crutchfield, James P.

2016-02-01

We introduce a family of Maxwellian Demons for which correlations among information bearing degrees of freedom can be calculated exactly and in compact analytical form. This allows one to precisely determine Demon functional thermodynamic operating regimes, when previous methods either misclassify or simply fail due to approximations they invoke. This reveals that these Demons are more functional than previous candidates. They too behave either as engines, lifting a mass against gravity by extracting energy from a single heat reservoir, or as Landauer erasers, consuming external work to remove information from a sequence of binary symbols by decreasing their individual uncertainty. Going beyond these, our Demon exhibits a new functionality that erases bits not by simply decreasing individual-symbol uncertainty, but by increasing inter-bit correlations (that is, by adding temporal order) while increasing single-symbol uncertainty. In all cases, but especially in the new erasure regime, exactly accounting for informational correlations leads to tight bounds on Demon performance, expressed as a refined Second Law of thermodynamics that relies on the Kolmogorov-Sinai entropy for dynamical processes and not on changes purely in system configurational entropy, as previously employed. We rigorously derive the refined Second Law under minimal assumptions and so it applies quite broadly—for Demons with and without memory and input sequences that are correlated or not. We note that general Maxwellian Demons readily violate previously proposed, alternative such bounds, while the current bound still holds. As such, it broadly describes the minimal energetic cost of any computation by a thermodynamic system.

NASA's Marshall Space Flight Center conducted liquid methane testing in November 2006 using the multipurpose hydrogen test bed outfitted with a spray bar thermodynamic vent system (TVS). The basic objective was to identify any unusual or unique thermodynamic characteristics associated with densified methane that should be considered in the design of space-based TVSs. Thirteen days of testing were performed with total tank heat loads ranging from 720 to 420 W at a fill level of approximately 90%. It was noted that as the fluid passed through the Joule-Thompson expansion, thermodynamic conditions consistent with the pervasive presence of metastability were indicated. This Technical Publication describes conditions that correspond with metastability and its detrimental effects on TVS performance. The observed conditions were primarily functions of methane densification and helium pressurization; therefore, assurance must be provided that metastable conditions have been circumvented in future applications of thermodynamic venting to in-space methane storage.

Gravity as a thermodynamic phenomenon

OpenAIRE

Moustos, Dimitris

2017-01-01

The analogy between the laws of black hole mechanics and the laws of thermodynamics led Bekenstein and Hawking to argue that black holes should be considered as real thermodynamic systems that are characterised by entropy and temperature. Black hole thermodynamics indicates a deeper connection between thermodynamics and gravity. We review and examine in detail the arguments that suggest an interpretation of gravity itself as a thermodynamic theory.

Deconstructing thermodynamic parameters of a coupled system from site-specific observables.

Science.gov (United States)

Chowdhury, Sandipan; Chanda, Baron

2010-11-02

Cooperative interactions mediate information transfer between structural domains of a protein molecule and are major determinants of protein function and modulation. The prevalent theories to understand the thermodynamic origins of cooperativity have been developed to reproduce the complex behavior of a global thermodynamic observable such as ligand binding or enzyme activity. However, in most cases the measurement of a single global observable cannot uniquely define all the terms that fully describe the energetics of the system. Here we establish a theoretical groundwork for analyzing protein thermodynamics using site-specific information. Our treatment involves extracting a site-specific parameter (defined as χ value) associated with a structural unit. We demonstrate that, under limiting conditions, the χ value is related to the direct interaction terms associated with the structural unit under observation and its intrinsic activation energy. We also introduce a site-specific interaction energy term (χ(diff)) that is a function of the direct interaction energy of that site with every other site in the system. When combined with site-directed mutagenesis and other molecular level perturbations, analyses of χ values of site-specific observables may provide valuable insights into protein thermodynamics and structure.

The public information aspects of nuclear regulatory inspection in the United States

International Nuclear Information System (INIS)

Volgenau, E.

1977-01-01

The public information aspects of the regulation of nuclear power present a unique set of problems. Not only must the regulators communicate often complex technical information to the public, they must also assure the public, the press and the legislative bodies of the adequacy of the regulatory process and the safety of power plant operations. The United States Nuclear Regulatory Commission (NRC), recognizing the importance of a continuing, open dialogue with the public, has placed particular emphasis on informing the public of its operations. NRC's experiences have been both good and bad. On balance, however, the NRC believes it is following the best course by conducting its operations openly and candidly. (author)

Thermodynamic estimation: Ionic materials

International Nuclear Information System (INIS)

Glasser, Leslie

2013-01-01

Thermodynamics establishes equilibrium relations among thermodynamic parameters (“properties”) and delineates the effects of variation of the thermodynamic functions (typically temperature and pressure) on those parameters. However, classical thermodynamics does not provide values for the necessary thermodynamic properties, which must be established by extra-thermodynamic means such as experiment, theoretical calculation, or empirical estimation. While many values may be found in the numerous collected tables in the literature, these are necessarily incomplete because either the experimental measurements have not been made or the materials may be hypothetical. The current paper presents a number of simple and relible estimation methods for thermodynamic properties, principally for ionic materials. The results may also be used as a check for obvious errors in published values. The estimation methods described are typically based on addition of properties of individual ions, or sums of properties of neutral ion groups (such as “double” salts, in the Simple Salt Approximation), or based upon correlations such as with formula unit volumes (Volume-Based Thermodynamics). - Graphical abstract: Thermodynamic properties of ionic materials may be readily estimated by summation of the properties of individual ions, by summation of the properties of ‘double salts’, and by correlation with formula volume. Such estimates may fill gaps in the literature, and may also be used as checks of published values. This simplicity arises from exploitation of the fact that repulsive energy terms are of short range and very similar across materials, while coulombic interactions provide a very large component of the attractive energy in ionic systems. Display Omitted - Highlights: • Estimation methods for thermodynamic properties of ionic materials are introduced. • Methods are based on summation of single ions, multiple salts, and correlations. • Heat capacity, entropy

Koszul Information Geometry and Souriau Geometric Temperature/Capacity of Lie Group Thermodynamics

Directory of Open Access Journals (Sweden)

Frédéric Barbaresco

2014-08-01

Full Text Available The François Massieu 1869 idea to derive some mechanical and thermal properties of physical systems from “Characteristic Functions”, was developed by Gibbs and Duhem in thermodynamics with the concept of potentials, and introduced by Poincaré in probability. This paper deals with generalization of this Characteristic Function concept by Jean-Louis Koszul in Mathematics and by Jean-Marie Souriau in Statistical Physics. The Koszul-Vinberg Characteristic Function (KVCF on convex cones will be presented as cornerstone of “Information Geometry” theory, defining Koszul Entropy as Legendre transform of minus the logarithm of KVCF, and Fisher Information Metrics as hessian of these dual functions, invariant by their automorphisms. In parallel, Souriau has extended the Characteristic Function in Statistical Physics looking for other kinds of invariances through co-adjoint action of a group on its momentum space, defining physical observables like energy, heat and momentum as pure geometrical objects. In covariant Souriau model, Gibbs equilibriums states are indexed by a geometric parameter, the Geometric (Planck Temperature, with values in the Lie algebra of the dynamical Galileo/Poincaré groups, interpreted as a space-time vector, giving to the metric tensor a null Lie derivative. Fisher Information metric appears as the opposite of the derivative of Mean “Moment map” by geometric temperature, equivalent to a Geometric Capacity or Specific Heat. We will synthetize the analogies between both Koszul and Souriau models, and will reduce their definitions to the exclusive Cartan “Inner Product”. Interpreting Legendre transform as Fourier transform in (Min,+ algebra, we conclude with a definition of Entropy given by a relation mixing Fourier/Laplace transforms: Entropy = (minus Fourier(Min,+ o Log o Laplace(+,X.

2016-06-01

Full Text Available The study aims at exploring the needs of a broad group of stakeholders of Malaysian public universities with respect to information items that should be disclosed in the university annual report, and their views on the disclosure importance of the items. This is a preliminary study towards the effort to develop an accountability reporting framework for Malaysian public universities. A questionnaire survey on the universities‟ stakeholders representing each stakeholder group which include policy makers, students, parents, employers, the public, university management and employees, suppliers and oversight entities was carried out in order to identify and confirm the stakeholders‟ disclosure needs. It is expected that the needs of the stakeholders in terms of information to be reported are comprehensive which include financial and non-financial information; and there are differences in the views on the disclosure importance of information among the stakeholder groups. The findings of this study provide a clear understanding of the information that should be disclosed in the annual reports of Malaysian public universities for accountability purpose. The findings may potentially assist the public universities to improve the way they discharge their public accountability through annual reporting.

Informing the public about the risks from ionizing radiation

Energy Technology Data Exchange (ETDEWEB)

Slovic, P; Fischhoff, B; Lichtenstein, S [Perceptronics, Eugene, OR (USA)

1981-10-01

Designers of programs for informing the public about radiation hazards need to consider the difficulties inherent in communicating highly technical information about risk. To be effective, information campaigns must be buttressed by empirical research aimed at determining what people know, what they want to know, and how best to convey that information. Drawing upon studies of risk perception, some of the problems that any information program must confront are described.

Public attitudes to genomic science: an experiment in information provision.

Sturgis, Patrick; Brunton-Smith, Ian; Fife-Schaw, Chris

2010-03-01

We use an experimental panel study design to investigate the effect of providing "value-neutral" information about genomic science in the form of a short film to a random sample of the British public. We find little evidence of attitude change as a function of information provision. However, our results show that information provision significantly increased dropout from the study amongst less educated respondents. Our findings have implications both for our understanding of the knowledge-attitude relationship in public opinion toward genomic science and for science communication more generally.

How to build public information and understanding : some French examples

International Nuclear Information System (INIS)

Bergeonneau, P.

1998-01-01

Public perception of nuclear issues and of the environmental impact is largely dependent on the general public's knowledge and understanding of complex scientific and technical matters which characterize the nuclear world, and on information provided by mass media which primarily tends to emphasize dramatic aspects. Consequently public information must be provided as completely and in as straightforward a manner as possible, and be adapted for people who do not have a clear understanding of nuclear technologies. Information must be objective in all cases, in order to increase credibility over time. This is important because confidence in scientists, and more generally in technical progress, has been eroded. In addition, when providing information, one has to anticipate events as much as possible in order to avoid misunderstandings when crises occur. Explanations during crises will then be better understood and confidence will be maintained. Examples of campaigns undertaken by the French Atomic Energy Commission are given in this paper. (author)

This paper reviews the licensing procedures for nuclear installations in various European countries and examines the form, content and methods selected for information and consultation of the public. The author stresses the importance of this stage in the procedure, both for the nuclear operator and the public authorities, given the population's concern about the environment. He concludes that, irrespective of its complexity, the nuclear field cannot remain the concern of a few initiates competent to take decisions and that, consequently, this implies creation of new information systems to meet the public's desire to participate more directly in the process.

In the present work we develop a strictly Hamiltonian approach to Thermodynamics. A thermodynamic description based on symplectic geometry is introduced, where all thermodynamic processes can be described within the framework of Analytic Mechanics. Our proposal is constructed on top of a usual symplectic manifold, where phase space is even dimensional and one has well-defined Poisson brackets. The main idea is the introduction of an extended phase space where thermodynamic equations of state are realized as constraints. We are then able to apply the canonical transformation toolkit to thermodynamic problems. Throughout this development, Dirac’s theory of constrained systems is extensively used. To illustrate the formalism, we consider paradigmatic examples, namely, the ideal, van der Waals and Clausius gases. - Highlights: • A strictly Hamiltonian approach to Thermodynamics is proposed. • Dirac’s theory of constrained systems is extensively used. • Thermodynamic equations of state are realized as constraints. • Thermodynamic potentials are related by canonical transformations.

Fischer, Patrick Tobias; Zöllner, Christian; Hoffmann, Thilo; Piatza, Sebastian; Hornecker, Eva

2013-01-01

Media facades (often characterized as a building's digital skin) are public displays that substitute dynamic details and information for usually static structures. SMSlingshot is a media facade system at the confluence of art, architecture, and technology design in the context of urban human-computer interaction. It represents a participative approach to public displays that enlivens public spaces and fosters civic and social dialogue as an alternative to advertising and service-oriented information displays. Observations from SMSlingshot's implementation at festival exhibitions provide insight into the roles of scale, distance, and the spatial situation of media facade contexts. The lessons learned apply to most public-display situations and will be useful for designers and developers of this new medium in urban spaces.

Why public information works: Research findings on organizational and individual impact

International Nuclear Information System (INIS)

Bisconti, A.S.

1989-01-01

Broad and growing public recognition of the importance of nuclear energy in the United States is evident in the public opinion polls, continued defeat of antinuclear referenda, positive Congressional actions, and open support by politicians-from the National Conference of State Legislatures to President Bush. At leadership levels, the need to address the looming electricity crisis without increasing dependence on foreign oil or greenhouse gas emissions is being voiced increasingly. Within this context, the industry is beginning to be successful in getting its message across to the American public through national advertising and media and public relations programs of the U.S. Council for Energy Awareness (USCEA). And the author knows that the American Nuclear Society (ANS) Public Information Committee is working hard in complementary kinds of public education. Research shows that the public's attitudes toward nuclear energy become more favorable when they are exposed to public information and that a more active scientific community could greatly increase public recognition of the benefits that nuclear energy provides

Technology information transfer in public outreach - a new approach

1994-01-01

The timely and accurate dissemination to the public of information derived from the site characterization activities on the Yucca Mountain Site Characterization Project (YMP) has sometimes been difficult to achieve. The YMP has many participants who are involved in the gathering and analysis of scientific and engineering data for site characterization. The diversity of the scientific disciplines involved, the uncentralized location of the participant organizations, the difficulty of being able to ask the right questions of the right people, and the translation of technical jargon into understandable terms are but a few of the challenges. The public outreach program of the YMP has done an excellent job of compiling and distributing information over the past few years, but, with the diversity and expansion of field activities in the last two years, the job has become more formidable. A new approach to help resolve this obstacle was instituted in April of 1993, and has been successful in achieving a much more timely and user-friendly discussion of technical information for the public. What is the new approach? The assignment of a technical expert to the public outreach staff whose job is to know what is going on, who is doing what, and what the results are. Based on that knowledge, factual summaries can be generated rapidly and presented to the public in the context of the overall project goals and in a form suitable for a wide range of audiences

Applied Chemical Engineering Thermodynamics provides the undergraduate and graduate student of chemical engineering with the basic knowledge, the methodology and the references he needs to apply it in industrial practice. Thus, in addition to the classical topics of the laws of thermodynamics,pure component and mixture thermodynamic properties as well as phase and chemical equilibria the reader will find: - history of thermodynamics - energy conservation - internmolecular forces and molecular thermodynamics - cubic equations of state - statistical mechanics. A great number of calculated problems with solutions and an appendix with numerous tables of numbers of practical importance are extremely helpful for applied calculations. The computer programs on the included disk help the student to become familiar with the typical methods used in industry for volumetric and vapor-liquid equilibria calculations.

Thermodynamics-based network analysis through the introduction of thermodynamic constraints in metabolic models allows a deeper analysis of metabolism and guides pathway engineering. The number and the areas of applications of thermodynamics-based network analysis methods have been increasing in the last ten years. We review recent applications of these methods and we identify the areas that such analysis can contribute significantly, and the needs for future developments. We find that organisms with multiple compartments and extremophiles present challenges for modeling and thermodynamics-based flux analysis. The evolution of current and new methods must also address the issues of the multiple alternatives in flux directionalities and the uncertainties and partial information from analytical methods.

On Thermodynamic Interpretation of Transfer Entropy

Directory of Open Access Journals (Sweden)

Don C. Price

2013-02-01

Full Text Available We propose a thermodynamic interpretation of transfer entropy near equilibrium, using a specialised Boltzmann’s principle. The approach relates conditional probabilities to the probabilities of the corresponding state transitions. This in turn characterises transfer entropy as a difference of two entropy rates: the rate for a resultant transition and another rate for a possibly irreversible transition within the system affected by an additional source. We then show that this difference, the local transfer entropy, is proportional to the external entropy production, possibly due to irreversibility. Near equilibrium, transfer entropy is also interpreted as the difference in equilibrium stabilities with respect to two scenarios: a default case and the case with an additional source. Finally, we demonstrated that such a thermodynamic treatment is not applicable to information flow, a measure of causal effect.

Nonequilibrium Thermodynamics of Driven Disordered Materials

Science.gov (United States)

Bouchbinder, Eran

2011-03-01

We present a nonequilibrium thermodynamic framework for describing the dynamics of driven disordered solids (noncrystalline solids near and below their glass temperature, soft glassy materials such as colloidal suspensions and heavily dislocated polycrystalline solids). A central idea in our approach is that the set of mechanically stable configurations, i.e. the part of the system that is described by inherent structures, evolves slowly as compared to thermal vibrations and is characterized by an effective disorder temperature. Our thermodynamics-motivated equations of motion for the flow of energy and entropy are supplemented by coarse-grained internal variables that carry information about the relevant microscopic physics. Applications of this framework to amorphous visco-plasticity (Shear-Transformation-Zone theory), glassy memory effects (the Kovacs effect) and dislocation-mediated polycrystalline plasticity will be briefly discussed.

Clarifying the link between von Neumann and thermodynamic entropies

Science.gov (United States)

Deville, Alain; Deville, Yannick

2013-01-01

The state of a quantum system being described by a density operator ρ, quantum statistical mechanics calls the quantity - kTr( ρln ρ), introduced by von Neumann, its von Neumann or statistical entropy. A 1999 Shenker's paper initiated a debate about its link with the entropy of phenomenological thermodynamics. Referring to Gibbs's and von Neumann's founding texts, we replace von Neumann's 1932 contribution in its historical context, after Gibbs's 1902 treatise and before the creation of the information entropy concept, which places boundaries into the debate. Reexamining von Neumann's reasoning, we stress that the part of his reasoning implied in the debate mainly uses thermodynamics, not quantum mechanics, and identify two implicit postulates. We thoroughly examine Shenker's and ensuing papers, insisting upon the presence of open thermodynamical subsystems, imposing us the use of the chemical potential concept. We briefly mention Landau's approach to the quantum entropy. On the whole, it is shown that von Neumann's viewpoint is right, and why Shenker's claim that von Neumann entropy "is not the quantum-mechanical correlate of thermodynamic entropy" can't be retained.

Connecting thermodynamics and economics: well-lit roads and burned bridges.

Science.gov (United States)

Glucina, Mark David; Mayumi, Kozo

2010-01-01

Almost 40 years have passed since Georgescu-Roegen's seminal work, The Entropy Law and the Economic Process. During this time there has been much debate on the relevance of thermodynamics to economics, and many attempts to build bridges between the two. There has also been much confusion as to what the laws of thermodynamics actually say. This article clearly explains heat, work, and the thermodynamic laws, the meaning of entropy, and the importance of kinetics as a barrier to thermodynamically favorable processes. The two most important misunderstandings in the literature, namely entropy as disorder, and entropy as a measure of information, are highlighted. Reviewing the literature shows that thermodynamics is most relevant for building a descriptive model, or preanalytic vision of economics, because it implies physical constraints on production and consumption. Similarly, it suggests that there may be serious flaws with neoclassical economic models, and in particular the primacy of sustained growth. However, thermodynamics does not seem to aid mathematical modeling in economics, nor does it provide normative insights. As an aid to energy policy, thermodynamics is useful for assessing the feasibility of technology options--those that have the potential to meet our goals, and should be counted as options, and those that should not. But it does not provide a prescription outside of this technical realm. Factors, such as environmental impact, cost, and social acceptability, will ultimately determine which technically feasible options are most desirable.

Quantum Rényi relative entropies affirm universality of thermodynamics.

Science.gov (United States)

Misra, Avijit; Singh, Uttam; Bera, Manabendra Nath; Rajagopal, A K

2015-10-01

We formulate a complete theory of quantum thermodynamics in the Rényi entropic formalism exploiting the Rényi relative entropies, starting from the maximum entropy principle. In establishing the first and second laws of quantum thermodynamics, we have correctly identified accessible work and heat exchange in both equilibrium and nonequilibrium cases. The free energy (internal energy minus temperature times entropy) remains unaltered, when all the entities entering this relation are suitably defined. Exploiting Rényi relative entropies we have shown that this "form invariance" holds even beyond equilibrium and has profound operational significance in isothermal process. These results reduce to the Gibbs-von Neumann results when the Rényi entropic parameter α approaches 1. Moreover, it is shown that the universality of the Carnot statement of the second law is the consequence of the form invariance of the free energy, which is in turn the consequence of maximum entropy principle. Further, the Clausius inequality, which is the precursor to the Carnot statement, is also shown to hold based on the data processing inequalities for the traditional and sandwiched Rényi relative entropies. Thus, we find that the thermodynamics of nonequilibrium state and its deviation from equilibrium together determine the thermodynamic laws. This is another important manifestation of the concepts of information theory in thermodynamics when they are extended to the quantum realm. Our work is a substantial step towards formulating a complete theory of quantum thermodynamics and corresponding resource theory.

Energy Equivalence of Information in the Mitochondrion and the Thermodynamic Efficiency of ATP Synthase.

Science.gov (United States)

Matta, Chérif F; Massa, Lou

2015-09-01

Half a century ago, Johnson and Knudsen resolved the puzzle of the apparent low efficiency of the kidney (∼ 0.5%) compared to most other bodily organs (∼ 40%) by taking into account the entropic cost of ion sorting, the principal function of this organ. Similarly, it is shown that the efficiency of energy transduction of the chemiosmotic proton-motive force by ATP synthase is closer to 90% instead of the oft-quoted textbook value of only 60% when information theoretic considerations are applied to the mitochondrion. This high efficiency is consistent with the mechanical energy transduction of ATP synthase known to be close to the 100% thermodynamic limit. It would have been wasteful for evolution to maximize the mechanical energy transduction to 100% while wasting 40% of the chemiosmotic free energy in the conversion of the proton-motive force into mechanical work before being captured as chemical energy in adenosine 5'-triphosphate.

Full Text Available The development of a country depends greatly on how much information its citizenry are exposed to. Information is so crucial that it has been recognized as the fifth factor of production. Information has no substitute when it comes to the national development because it has been identified as the driver of economic growth and productivity. The paper discussed the roles of public libraries in Nigeria and also examined various ways in which public libraries can help curb unemployment among youths by providing them with timely and accurate information. It concluded that public libraries should identify themselves with the aspiration of economic development of the country.

Thermodynamic assessment of the Pb-Sr system

Zhang H.

2017-01-01

Full Text Available The Pb-Sr system has been critically reviewed and modeled by means of the CALPHAD (CALculation of PHAse Diagrams approach. It contains seven stoichiometric compounds, i.e. SrPb3, Sr3Pb5, Sr2Pb3, SrPb, Sr5Pb4, Sr5Pb3 and Sr2Pb, in which the SrPb3 and Sr2Pb phases melt congruently, and the other five phases form via peritectic reactions. The enthalpies of formation for the intermetallic compounds at 0 K are provided by first-principles calculations. The liquid, fcc and bcc phases are modeled as substitutional solution phases. Both Redlich-Kister and exponential polynomials are used to describe the excess Gibbs energy of the liquid. Two sets of self-consistent thermodynamic parameters are obtained by considering reliable experimental data and the computed enthalpies of formation. Comprehensive comparisons between the calculated and measured phase diagram and thermodynamic data show that the experimental information is satisfactorily accounted for by the present thermodynamic description.

Public consultation in public policy information: a state-of-the-art report

Bishop, A.B.; McKee, M.; Hansen, R.D.

1977-01-01

The purpose of the National Waste Terminal Storage (NWTS) Program is to site, construct and operate nuclear waste repositories at several locations. Recent experience indicates that the public is aware of the problems of nuclear waste disposal, and correspondingly there is public concern about how and where to dispose of nuclear wastes. The selection of sites involves a wide range of considerations including geological, technical and environmental feasibility. In addition to these, it is important that societal acceptance of repository options also be taken into account in moving foward with the NWTS Program. Such an incorporation of social considerations and preferences correspondingly implies the need for public consultation in the site selection process. In exploring the concept and state-or-the-art of public involvement in public policy decision, a number of important questions are relevant: (1) What are the basic objectives of public participation in policy formation and program decisions. (2) Who are the ''publics'' that should be involved and how can they be identified. (3) What information should be communicated between the agency and the publics. (4) What techniques are available to elicit public participation and involvement and what are their capabilities. At the outset, it should be noted that the purpose of this paper in addressing these questions is not to design public participation procedures for the NWTS program. Rather, the above are questions that provide a broad framework for developing an understanding of citizen participation in public policy decisions, such as nuclear waste disposal. In this sense, the following discussion is to provide a context and guidance for approaching the problem of organizing and structuring involvement in the NWTS program. Annotated bibliography of 95 references is included

Statistical Thermodynamics and Microscale Thermophysics

Science.gov (United States)

Carey, Van P.

1999-08-01

Many exciting new developments in microscale engineering are based on the application of traditional principles of statistical thermodynamics. In this text Van Carey offers a modern view of thermodynamics, interweaving classical and statistical thermodynamic principles and applying them to current engineering systems. He begins with coverage of microscale energy storage mechanisms from a quantum mechanics perspective and then develops the fundamental elements of classical and statistical thermodynamics. Subsequent chapters discuss applications of equilibrium statistical thermodynamics to solid, liquid, and gas phase systems. The remainder of the book is devoted to nonequilibrium thermodynamics of transport phenomena and to nonequilibrium effects and noncontinuum behavior at the microscale. Although the text emphasizes mathematical development, Carey includes many examples and exercises to illustrate how the theoretical concepts are applied to systems of scientific and engineering interest. In the process he offers a fresh view of statistical thermodynamics for advanced undergraduate and graduate students, as well as practitioners, in mechanical, chemical, and materials engineering.

Situation Concerning Public Information about and Involvement in the Decision-Making Processes in the Nuclear Sector. Public Opinion Review

This report summarizes the CIEMAT's contribution to the study S ituation concerning Public Information about and Involvement in the Decision-Making Processes in the Nuclear Sector , contract number TREN/ 04/NUC/ S07.39556 between the European Commission and Mutadis Consultants. The research was composed by Mutadis Consultants and CEPN (Nuclear Protection Evaluation Centre) (France), University of Aberdeen (UK) and CIEMAT (Spain). The objective of the project was to build a detailed overview of the EU situation regarding information and participation practices in the nuclear domain, provide an elaborated assessment, and to produce reporting and recommendations in the field. CIEMAT contribution' focused on the review of public opinion polis. Thus, Eurobarometers Standard Surveys (EBs) were analysed to report about the European citizens' public opinion regarding public Information and participation in the nuclear field. Additionally, the International Social Survey Program (ISSP), and some additional national polis were analysed. In terms of the EU public opinion, the follow up of the public information and participation domains receiving as much attention as necessary. Extremely few questions dealing with the subject were identified in the Eurobarometers, the national polis and the ISSP (International Social Survey Program) surveys reviewed in this study. An unambiguous illustration of this lack of attention is the fact that no questions dealing with public participation issues emerged in the n uclear EBs u ntil 1998. Even though, Eurobarometers (EBs) still provide an invaluable source of information on the topics we are interested on at the EU allowing longitudinal descriptions (trend analysis) of some key issues in our area of interest.

Full Text Available Every human being has equal right for accessing to the transportation. Difable persons that have different ability also have the same right. The provision of the accessibility and information facility in public transport is not fully meet difable need and therefore difable persons have difficulties in accessibility and information while using public transports. This research will investigate the difable perceptions about accessibility and traveler information for the public transport in Jakarta. Questionnaire method will be used for this purpose and then analyzed by Importance Performance Analysis. The improvement for the transport infrastructure and information system will be elaborated. The findings of the research could be used as input for the local authority while planning or re-construction public transport infrastructure and information system so that difable persons become more accessible and convenience. The study results show that the average value of the perceived performance for the accessibility is 2.78 from 5 scales. This means the performance of the accessibility in overall is fairly. For the information facility, the average performance is 3.11 that meaning the performance in overall is good. The respondents required the provision of waiting room for difable persons as a priority. The information about the departure of the vehicle should been improved as priority to be increased. Furthermore, it is obtained that the Customer Satisfaction Index (CSI value for accessibility is 56%. This indicates the entire respondents satisfied sufficiently with the accessibility facility. Also, 62% of the CSI value shows that the respondents satisfied sufficiently with the provided information.

Strategy of the Romanian Public Information Policy in the Nuclear Field

International Nuclear Information System (INIS)

Stiopol, Mihaela; Manole, Felicia; Paunescu, Aurelia; Petran, Catalina; Chiper, Livia

1998-01-01

In the framework the Romania's nuclear power program the first Romanian NPP has been built at Cernavoda and the Unit 1, based on a CANDU type reactor, was commissioned on December 2, 1996. The start of the entire nuclear program in Romania, some 20 years ago, was a high level government decision with no public hearing or acceptance, either, but obviously based on economic and political considerations. After 1990 favorable and unfavorable articles in the mass media, most of them lacking of technical background, had led to distorted and false perception of information. The strategy of public information policy in the nuclear field should be guided by the following facts: a) the public perception of the nuclear energy problems in general, and of nuclear power, in particular, is deeply deformed by the ignorance in the domain; b) first of all the public fears for its health menaced by radiation and radioactive wastes; c) the public due not know the actual dimension and potential of the Romanian industry in this field, the qualitative progress brought about by the implementation of the nuclear program in the Romania's economy; d) the public vulnerability when exposed to the mass media which, owing to its rush towards sensational or due to the lack of knowledge in the field, rather often have launched simple, unfounded speculations. The paper presents the basic principles which are underlying the public information program and lists suggestions for the future activity concerning: A - the educational programs addressed to young people; B - development of computer-assisted educational programs; C - the relationship with mass media; D - accomplishing an adequate information through publications; E - organizing and/or participating in exhibitions displaying nuclear power development; F - advertising actions related to promotion of Unit 2 - 5 project at Cernavoda NPP

The public multi-coil information (PUMCIN) policy.

Science.gov (United States)

Juchem, Christoph; de Graaf, Robin A

2017-11-01

Multi-coil (MC) magnetic field modeling has emerged as a viable alternative to conventional field generation based on spherical harmonic shapes, and an active MC community is forming. Although all MC applications share the same modeling concept, the specific MC designs can largely differ as a result of disparities in region of interest (eg, human versus rodent), intended MR application (eg, B 0 shimming versus spatial encoding), or other experimental constraints (eg, available bore space or integration with radiofrequency technology). To date, a lack of detailed information on existing MC designs complicates the assessment and precludes a meaningful comparison. Here, we suggest that future publications involving the MC technique not only report the benefits for the application at hand, but also include an explicit description of the MC wire pattern used. This public multi-coil information (PUMCIN) policy represents a voluntary commitment to promoting free public access to the details necessary for reproducing and benefiting from MC research. The PUMCIN policy is expected to initiate a paradigm shift with respect to the way MC innovation is reported. By setting an example, we hope to encourage the evolving MC community to maximize the benefits for science and society by embracing it.

Public information on radioactive waste management in the Netherlands

International Nuclear Information System (INIS)

Vrijen, J.

1993-01-01

In the Netherlands, the public image of radioactive waste and the management, related with it, was very negative in the early eighties. One of the reasons obviously was that the radioactive waste management system was not clearly defined up till then. The Centrale Organisatie Voor Radioacief Afval, COVRA, was founded in 1982 by Dutch government; COVRA had the task to reorganize the waste management business and also obtained the task to inform the public about the waste issue and what had to be done with it. It was possible to create a positive atmosphere for public information by bringing the public to the waste, actually showing what it was, what we do with it, what the result of this all will be and what we consider to be the actual risks involved, without exaggerating it. We tried to be as open as possible, to create access to the waste as far as possible, and we learned that the waste should be the center point of the visitors center. We tried to avoid that the public would not be able to see for itself what has be done to secure the surroundings and the environment for possibly negative effects resulting from the waste or its treatment or the interim storage of it

Moustaine, D., E-mail: mostainedris@gmail.com; Mahdouk, K.

2016-07-15

Phase relationships in Nd–Au binary system have been thermodynamically assessed by means of the CALPHAD technique through Thermo–Calc software package based on the experiment information of phase equilibria and thermodynamic properties from the published literature data. The excess Gibbs energy functions of the solution phases including liquid, fcc-A1, bcc-A2, and dhcp were formulated with Redlich–Kister polynomial functions. The two–sublattice energy model was employed to describe the Nd{sub 14}Au{sub 51} phase which exhibits a homogeneity range. The intermetallic compounds Nd{sub 2}Au, NdAu, Nd{sub 3}Au{sub 4}, Nd{sub 17}Au{sub 36}, and NdAu{sub 6} were treated as stoichiometric phases. A set of self-consistent thermodynamic parameters formulating the Gibbs energy of various phases in the Nd–Au binary system were then obtained. A much better agreement was achieved between the calculated results and the reported experimental data. - Highlights: • The Nd–Au has been re-assessed using the latest experimental results. • The intermetallic compound Nd{sub 14}Au{sub 51} was treated by a two–sublattice model. • The errors of related modelling presented in previous articles have been modified. • A self–consistent thermodynamic description of the Nd–Au system was obtained.

Stimulating Contributions to Public Goods through Information Feedback: Some Experimental Results.

Directory of Open Access Journals (Sweden)

Marco A Janssen

Full Text Available In traditional public good experiments participants receive an endowment from the experimenter that can be invested in a public good or kept in a private account. In this paper we present an experimental environment where participants can invest time during five days to contribute to a public good. Participants can make contributions to a linear public good by logging into a web application and performing virtual actions. We compared four treatments, with different group sizes and information of (relative performance of other groups. We find that information feedback about performance of other groups has a small positive effect if we control for various attributes of the groups. Moreover, we find a significant effect of the contributions of others in the group in the previous day on the number of points earned in the current day. Our results confirm that people participate more when participants in their group participate more, and are influenced by information about the relative performance of other groups.

Thermodynamics of adaptive molecular resolution.

Science.gov (United States)

Delgado-Buscalioni, R

2016-11-13

A relatively general thermodynamic formalism for adaptive molecular resolution (AMR) is presented. The description is based on the approximation of local thermodynamic equilibrium and considers the alchemic parameter λ as the conjugate variable of the potential energy difference between the atomistic and coarse-grained model Φ=U (1) -U (0) The thermodynamic formalism recovers the relations obtained from statistical mechanics of H-AdResS (Español et al, J. Chem. Phys. 142, 064115, 2015 (doi:10.1063/1.4907006)) and provides relations between the free energy compensation and thermodynamic potentials. Inspired by this thermodynamic analogy, several generalizations of AMR are proposed, such as the exploration of new Maxwell relations and how to treat λ and Φ as 'real' thermodynamic variablesThis article is part of the themed issue 'Multiscale modelling at the physics-chemistry-biology interface'. © 2016 The Author(s).

Public information on radioactive waste: a study of an emerging issue

International Nuclear Information System (INIS)

Bronfman, L.M.; Bronfman, B.H.; Regens, J.L.

1979-10-01

Through an analysis of information provided in the printed media on the topic of radioactive waste, the study analyzes the emergence of radioactive waste as a public issue in the press. Over eight hundred articles printed in both specialized and non-specialized sources from 1973 to 1978 have been content-analyzed in order to describe how the problem of radioactive waste is defined and what dimensions of the problems are receiving attention. Between 1973 and 1978, there was a substantial increase in the amount of information on the topic of radioactive waste available to the public through a variety of popular and specialized media sources. This increase coincides with documented public concern with the problem of radioactive waste. Discussions of radioactive waste have focused for all sources more frequently on themes not directly related to the technical problems of radioactive waste storage or isolation. A substantial amount of the information available to a variety of segments of the public is composed of discussions of real or perceived risk related to the existence of waste or to methods of disposing of it. In addition to risk, a substantial proportion of the discussions deal with institutional themes. Over time, the total amount of information on most dimensions of the radioactive waste problem has increased substantially. Institutional themes have gained relative to other issues over the three time periods. National and local press sources infrequently specify the form of waste being discussed thus providing evidence that the quality of technical information available to some members of the public is very low

Silicon in steel significantly affects alloy growth kinetics in the coating in general galvanizing, thereby changing the coating microstructure from the usual stratified Fe-Zn alloy layers to a mass of {zeta} crystallites surrounding by liquid zinc. The Zn-Fe-Si phase diagram and the relevant thermodynamic information have great importance for the galvanizing industry in developing remedies for this problem. In this work, the available information on the Fe-Zn-Si system, including all three binary systems was reviewed and re-evaluated, and ternary parameters were extracted from the available experimental data. By assuming all the binary intermetallic phases with the exception of the {delta}, {gamma}{sub 1}, and {gamma} phases, have no ternary solubility, a thermodynamic calculation of the Fe-Zn-Si system was carried out, and relevant isothermal and isopleths sections were calculated. Its applicability in galvanizing industry was discussed. There is a good agreement between the calculated and the experimentally determined phase boundaries.

The nuclear power public education and information program in the Philippines

International Nuclear Information System (INIS)

Garcia, E.A.; Natera, E.S.

1996-01-01

The nuclear power public education and information program aims to present the beneficial uses of radiation and nuclear energy. Considering that there are pros and cons to the use of nuclear energy, the program aims to give the public an objective and balanced view of this source of energy. A decision to use or not to use nuclear energy, to be sound,must be based on an adequate and objective knowledge of the atom and nuclear energy. Executive Order 243 created the Nuclear Power Steering committee including subcommittee on Nuclear Power Public Education and Information. This subcommittee is tasked to formulate an effective nuclear power public education and information program. Said program must include training component for science teachers in the high school and college levels and shall also work for the inclusion of nuclear related subjects in all engineering curriculum. It shall coordinate with the University of the Philippines for the revival of the M.S. in Nuclear Engineering Program of the university. This paper will discuss a brief history of nuclear power public education and awareness programs and the present and projected activities of this subcommittee. (author)

Stochastic Independence as a Resource for Small-Scale Thermodynamics

Science.gov (United States)

Lostaglio, Matteo; Mueller, Markus P.; Pastena, Michele

It is well-known in thermodynamics that the creation of correlations costs work. It seems then a truism that if a thermodynamic transformation A --> B is impossible, so will be any transformation that in sending A to B also correlates among them some auxiliary systems C. Surprisingly, we show that this is not the case for non-equilibrium thermodynamics of microscopic systems. On the contrary, the creation of correlations greatly extends the set of accessible states, to the point that we can perform on individual systems and in a single shot any transformation that would otherwise be possible only if the number of systems involved was very large. We also show that one only ever needs to create a vanishingly small amount of correlations (as measured by mutual information) among a small number of auxiliary systems (never more than three). The many, severe constraints of microscopic thermodynamics are reduced to the sole requirement that the non-equilibrium free energy decreases in the transformation. This shows that, in principle, reliable extraction of work equal to the free energy of a system can be performed by microscopic engines.

It is well known in thermodynamics that the creation of correlations costs work. It seems then a truism that if a thermodynamic transformation A →B is impossible, so will be any transformation that in sending A to B also correlates among them some auxiliary systems C . Surprisingly, we show that this is not the case for nonequilibrium thermodynamics of microscopic systems. On the contrary, the creation of correlations greatly extends the set of accessible states, to the point that we can perform on individual systems and in a single shot any transformation that would otherwise be possible only if the number of systems involved was very large. We also show that one only ever needs to create a vanishingly small amount of correlations (as measured by mutual information) among a small number of auxiliary systems (never more than three).

Molecular thermodynamics for cell biology as taught with boxes.

Mayorga, Luis S; López, María José; Becker, Wayne M

2012-01-01

Thermodynamic principles are basic to an understanding of the complex fluxes of energy and information required to keep cells alive. These microscopic machines are nonequilibrium systems at the micron scale that are maintained in pseudo-steady-state conditions by very sophisticated processes. Therefore, several nonstandard concepts need to be taught to rationalize why these very ordered systems proliferate actively all over our planet in seeming contradiction to the second law of thermodynamics. We propose a model consisting of boxes with different shapes that contain small balls that are in constant motion due to a stream of air blowing from below. This is a simple macroscopic system that can be easily visualized by students and that can be understood as mimicking the behavior of a set of molecules exchanging energy. With such boxes, the basic concepts of entropy, enthalpy, and free energy can be taught while reinforcing a molecular understanding of the concepts and stressing the stochastic nature of the thermodynamic laws. In addition, time-related concepts, such as reaction rates and activation energy, can be readily visualized. Moreover, the boxes provide an intuitive way to introduce the role in cellular organization of "information" and Maxwell's demons operating under nonequilibrium conditions.

Estimation of kinetic and thermodynamic ligand-binding parameters using computational strategies.

Science.gov (United States)

Deganutti, Giuseppe; Moro, Stefano

2017-04-01

Kinetic and thermodynamic ligand-protein binding parameters are gaining growing importance as key information to consider in drug discovery. The determination of the molecular structures, using particularly x-ray and NMR techniques, is crucial for understanding how a ligand recognizes its target in the final binding complex. However, for a better understanding of the recognition processes, experimental studies of ligand-protein interactions are needed. Even though several techniques can be used to investigate both thermodynamic and kinetic profiles for a ligand-protein complex, these procedures are very often laborious, time consuming and expensive. In the last 10 years, computational approaches have enormous potential in providing insights into each of the above effects and in parsing their contributions to the changes in both kinetic and thermodynamic binding parameters. The main purpose of this review is to summarize the state of the art of computational strategies for estimating the kinetic and thermodynamic parameters of a ligand-protein binding.

The Use of Geographic Information Systems in Public Services

Directory of Open Access Journals (Sweden)

Vladimir Senic

2017-12-01

Full Text Available With the further development of information and communication technology and a growing use of smart phones, the significance of Geographic Information System - GIS will indisputably continue to grow. This is supported by the fact that in the last decade geotechnology has been identified as one of the fastest growing technologies, along with biotechnology and nanotechnology. Even though GIS is increasingly being utilized in the Republic of Serbia, it appears that its use with some providers of public services is mainly deduced to showing spatial data with quite limited possibilities for a further analysis - which represents the essence of the use of GIS. The scope of this paper is to stress the outstanding analytical potential that GIS has in the domain of offering and improving various public services in the Republic of Serbia. The paper uses the examples of good practice in the sphere of the health system, public safety, rescue services and local government. The covered examples show that the use of the analytical component of GIS in everyday activities of the mentioned public services can make their work not only more transparent to the public, but considerably more efficient as well. This way, the analytical component of GIS enables decision-makers to improve the management of frequently limited available resources, while proving a higher level of the service quality to citizens as the final users.

Withholding differential risk information on legal consumer nicotine/tobacco products: The public health ethics of health information quarantines.

Science.gov (United States)

Kozlowski, Lynn T; Sweanor, David

2016-06-01

The United States provides an example of a country with (a) legal tobacco/nicotine products (e.g., snus, other smokeless tobacco, cigarettes) differing greatly in risks to health and (b) respected health information websites that continue to omit or provide incorrect differential risk information. Concern for the principles of individual rights, health literacy, and personal autonomy (making decisions for oneself), which are key principles of public health ethics, has been countered by utilitarian arguments for the use of misleading or limited information to protect public health overall. We argue that omitting key health relevant information for current or prospective consumers represents a kind of quarantine of health-relevant information. As with disease quarantines, the coercive effects of quarantining information on differential risks need to be justified, not merely by fears of net negative public health effects, but by convincing evidence that such measures are actually warranted, that public health overall is in imminent danger and that the danger is sufficient to override principles of individual autonomy. Omitting such health-relevant information for consumers of such products effectively blindfolds them and impairs their making informed personal choices. Moral psychological issues that treat all tobacco/nicotine products similarly may also be influencing the reluctance to inform on differential risks. In countries where tobacco/nicotine products are legally sold and also differ greatly in disease risks compared to cigarettes (e.g., smokeless tobacco and vape), science-based, comprehensible, and actionable health information (consistent with health literacy principles) on differential risks should be available and only reconsidered if it is established that this information is causing losses to population health overall.

Bioengineering thermodynamics of biological cells.

Science.gov (United States)

Lucia, Umberto

2015-12-01

Cells are open complex thermodynamic systems. They can be also regarded as complex engines that execute a series of chemical reactions. Energy transformations, thermo-electro-chemical processes and transports phenomena can occur across the cells membranes. Moreover, cells can also actively modify their behaviours in relation to changes in their environment. Different thermo-electro-biochemical behaviours occur between health and disease states. But, all the living systems waste heat, which is no more than the result of their internal irreversibility. This heat is dissipated into the environment. But, this wasted heat represent also a sort of information, which outflows from the cell toward its environment, completely accessible to any observer. The analysis of irreversibility related to this wasted heat can represent a new approach to study the behaviour of the cells themselves and to control their behaviours. So, this approach allows us to consider the living systems as black boxes and analyze only the inflows and outflows and their changes in relation to the modification of the environment. Therefore, information on the systems can be obtained by analyzing the changes in the cell heat wasted in relation to external perturbations. The bioengineering thermodynamics bases are summarized and used to analyse possible controls of the calls behaviours based on the control of the ions fluxes across the cells membranes.

Thermodynamics: The Unique Universal Science

Directory of Open Access Journals (Sweden)

Wassim M. Haddad

2017-11-01

Full Text Available Thermodynamics is a physical branch of science that governs the thermal behavior of dynamical systems from those as simple as refrigerators to those as complex as our expanding universe. The laws of thermodynamics involving conservation of energy and nonconservation of entropy are, without a doubt, two of the most useful and general laws in all sciences. The first law of thermodynamics, according to which energy cannot be created or destroyed, merely transformed from one form to another, and the second law of thermodynamics, according to which the usable energy in an adiabatically isolated dynamical system is always diminishing in spite of the fact that energy is conserved, have had an impact far beyond science and engineering. In this paper, we trace the history of thermodynamics from its classical to its postmodern forms, and present a tutorial and didactic exposition of thermodynamics as it pertains to some of the deepest secrets of the universe.

Managing minor incidents - Providing information for the public

International Nuclear Information System (INIS)

Joukovskaia, O.

1999-01-01

In April 26, 1999, 13 years will pass since the Chernobyl accident. It is the largest radiation catastrophe in its scale and prolonged consequences for the Republic of Belarus. Nearly 70% of radioactive materials released into the atmosphere as a result of the reactor accident deposited at the territory of Belarus. The Chernobyl catastrophe ad the post-Chernobyl processes led a large break of in lifestyle, values, orientations and everyday behaviour of the people on the contaminated territories. All these destructive changes are deflected as an anxious state due to the fear for children health status. As the time goes on, anxiety is not decreasing, but rather increasing. Residents of the contaminated regions are characterised by a high level of psychological stress which is related with two factors: the general socio-economic tension in the Republic of Belarus and presence of radioactive contamination of Chernobyl origin. Both factors do interact between one another. Thus, psychological consequences of the accident are connected not only with real contamination of the environment but also with the actions of the decisions makers, information of the mass media. This permits considering the stress of the population after the accident at the Chernobyl NPP as an 'informational' stress. The information stress calls for adequate activities aimed at reducing adverse consequences of its impact on health of the public. In so doing, one of the leading tasks of information rehabilitation of the people affected by the Chernobyl disaster is a problem of their realizing the fact it is possible to live in the affected territories. It is of utmost importance to help man correctly evaluate a level of real and imaginary threats which life after Chernobyl is fraught with, to give him/her an opportunity to thoughtfully opt for his/her line of behavior, prevent an individual from developing in such a direction that could result in a real threat to physical health. To achieve this goal

Bayesian quantification of thermodynamic uncertainties in dense gas flows

International Nuclear Information System (INIS)

Merle, X.; Cinnella, P.

2015-01-01

A Bayesian inference methodology is developed for calibrating complex equations of state used in numerical fluid flow solvers. Precisely, the input parameters of three equations of state commonly used for modeling the thermodynamic behavior of the so-called dense gas flows, – i.e. flows of gases characterized by high molecular weights and complex molecules, working in thermodynamic conditions close to the liquid–vapor saturation curve – are calibrated by means of Bayesian inference from reference aerodynamic data for a dense gas flow over a wing section. Flow thermodynamic conditions are such that the gas thermodynamic behavior strongly deviates from that of a perfect gas. In the aim of assessing the proposed methodology, synthetic calibration data – specifically, wall pressure data – are generated by running the numerical solver with a more complex and accurate thermodynamic model. The statistical model used to build the likelihood function includes a model-form inadequacy term, accounting for the gap between the model output associated to the best-fit parameters and the true phenomenon. Results show that, for all of the relatively simple models under investigation, calibrations lead to informative posterior probability density distributions of the input parameters and improve the predictive distribution significantly. Nevertheless, calibrated parameters strongly differ from their expected physical values. The relationship between this behavior and model-form inadequacy is discussed. - Highlights: • Development of a Bayesian inference procedure for calibrating dense-gas flow solvers. • Complex thermodynamic models calibrated by using aerodynamic data for the flow. • Preliminary Sobol analysis used to reduce parameter space. • Piecewise polynomial surrogate model constructed to reduce computational cost. • Calibration results show the crucial role played by model-form inadequacies

INFORMAL STRATEGIZING IN A PUBLIC ORGANIZATION

Directory of Open Access Journals (Sweden)

Marcelo Pedro Vieira

2013-09-01

Full Text Available Strategy as Practice analyzes what people do in relation to the development of strategy in organizations, providing insights into current issues in strategy that require a more micro level of understanding (JOHNSON et al., 2007. Considering the perspective of strategy as practice arising from the emerging strategies, we noticed the lack of studies to understand how these activities occur in a daily basis of organization characterizing as informal strategies (WHITTINGTON, 2007. Therefore, this study proposes to address this issue, showing the occurrence of informal strategizing at a public organization under the strategy-as-practice perspective. For this we held a qualitative research through a single case study (EISENHARDT, 1989 in a municipality in southern Brazil. Data were collected through semi-structured interviews with officials of different levels of the organization; direct observation, with notebook guide and analysis of documents provided by the organization, encouraging the triangulation of data. Informal strategies were mainly identified on customer service activities when an applicant’s request is not strictly met under the law or the legislation is dubious and opens room for double-meaning surveying, interpretation and information communication.

Following the decision of the French Secretary of State for Health in April 1996, an initial campaign of iodine tablet distribution, within a 10 km radius around nuclear plants was organized by the public authorities in 1997. This decision, which implicitly recognises nuclear risk, forced the public authorities and EDF to initiate communication on the risk, which had never been really addressed. It took the form essentially of an information campaign on the measures to protect the public in the event of a nuclear accident and in particular the effectiveness and methods of iodine protection.

Structure and thermodynamics of a mixture of patchy and spherical colloids: A multi-body association theory with complete reference fluid information

A mixture of solvent particles with short-range, directional interactions and solute particles with short-range, isotropic interactions that can bond multiple times is of fundamental interest in understanding liquids and colloidal mixtures. Because of multi-body correlations, predicting the structure and thermodynamics of such systems remains a challenge. Earlier Marshall and Chapman [J. Chem. Phys. 139, 104904 (2013)] developed a theory wherein association effects due to interactions multiply the partition function for clustering of particles in a reference hard-sphere system. The multi-body effects are incorporated in the clustering process, which in their work was obtained in the absence of the bulk medium. The bulk solvent effects were then modeled approximately within a second order perturbation approach. However, their approach is inadequate at high densities and for large association strengths. Based on the idea that the clustering of solvent in a defined coordination volume around the solute is related to occupancy statistics in that defined coordination volume, we develop an approach to incorporate the complete information about hard-sphere clustering in a bulk solvent at the density of interest. The occupancy probabilities are obtained from enhanced sampling simulations but we also develop a concise parametric form to model these probabilities using the quasichemical theory of solutions. We show that incorporating the complete reference information results in an approach that can predict the bonding state and thermodynamics of the colloidal solute for a wide range of system conditions.

Anomalons, recent copper-target experiments and the first law of thermodynamics

International Nuclear Information System (INIS)

Brandt, R.; Khan, H.A.; Krivopustov, M.I.

1991-01-01

A reanalysis of the old Alexander experiment, reporting on the anomalous behavior of pie in K-decays indicates that this anomalous behavior may be connected to a state of lower entropy or in other words to 'anomalous information', considering the well-known relation: negative entropy information. Now, recent copper-target experiments from the Synchrophasotron entail, that the wide-angle emission of hadrons in the reaction (44 GeV/sup 12/c + Cu) cannot be understood with concepts of physics, as known to the authors. However, this could be understood with 'anomalous information'. Further effects of this 'anomalous information' may be obtained in future studies with very massive heavy element targets irradiated with relativistic ions. The total production of neutrons in such a system could both be measured experimentally and calculated theoretically. As the calculations are based on the 1st Law of Thermodynamic, a significant excess of neutron fluxes beyond calculations may indicate the effete of anomalous information, even on the expense of the 1st law of Thermodynamics.

Solvation thermodynamics

CERN Document Server

Ben-Naim, Arieh

1987-01-01

This book deals with a subject that has been studied since the beginning of physical chemistry. Despite the thousands of articles and scores of books devoted to solvation thermodynamics, I feel that some fundamen­ tal and well-established concepts underlying the traditional approach to this subject are not satisfactory and need revision. The main reason for this need is that solvation thermodynamics has traditionally been treated in the context of classical (macroscopic) ther­ modynamics alone. However, solvation is inherently a molecular pro­ cess, dependent upon local rather than macroscopic properties of the system. Therefore, the starting point should be based on statistical mechanical methods. For many years it has been believed that certain thermodynamic quantities, such as the standard free energy (or enthalpy or entropy) of solution, may be used as measures of the corresponding functions of solvation of a given solute in a given solvent. I first challenged this notion in a paper published in 1978 b...

Creys-Malville: New strategy of communication, the Centre for Public Information

In this communication is exposed the list of a centre for public information in a french nuclear power plant: Creys-Malville also called Super Phenix. It is a prototype of high technology and an European realization. It can be used as breeder reactor, converter or incinerator. Three points take place here: no uranium shortage happened and then, it was not so urgent to develop a breeder reactor; an other point was Tchernobyl accident in 1986, and finally as a third point, ecologist movement is gaining ground. The nuclear power plant stopped the 3rd of july 1990, after a pollution of primary sodium, and there will be at least eighteen months before a re-starting. All these points allow to understand the situation in which we are to inform the public. We have to eliminate passion from the debate and talk about facts not symbols; We have to interest people by an easy understanding of nuclear industry in general and Creys-Malville in particular; We have to explain the actual situation of Creys-Malville and the impacts on regional economy; We must give to the public the means to have his own opinion and reflect on the long term. To do this, two welcome points: the first one called 'Belvedere' is out of the site, free access and provides general informations; The second one, Centre for Public Information, is at the entrance of the site but in supervised access, and gives informations on Creys-Malville facility

A survey of suppression of public health information by Australian governments.

Science.gov (United States)

Yazahmeidi, Boshra; Holman, C D'Arcy J

2007-12-01

It is cause for concern when a democratically elected government suppresses embarrassing information by hindering public health research or the publication of research findings. We conducted a survey of Australian public health academics to estimate the level of acts of suppression of research by Australian governments, to characterise these events, and to gather views on what interventions might be effective in curbing them. A total of 302 academics in 17 institutions completed a postal questionnaire in August 2006 (46% of 652 invited). The instrument sought details of suppression events they had witnessed since 2001. There were 142 suppression events, including 85 personally experienced by 21.2% (n=64) of respondents. The rates were higher in 2005/06 than in earlier years. No State or Territory was immune from suppression. Although governments most commonly hindered research by sanitising, delaying or prohibiting publications (66% of events), no part of the research process was unaffected. Researchers commonly believed their work was targeted because it drew attention to failings in health services (48%), the health status of a vulnerable group (26%), or pointed to a harm in the environment (11%). The government agency seeking to suppress the health information mostly succeeded (87%) and, consequently, the public was left uninformed or given a false impression. Respondents identified a full range of participative, cognitive, structural and legislative control strategies. The suppression of public health information is widely practised by Australian governments. Systemic interventions are necessary to preserve the integrity of public health research conducted with government involvement.

Highlights: ► All the literature data of Sn–Sr system is critically reviewed. ► First-principles calculation of enthalpy of formation is carried out for each compound. ► Thermodynamic parameters for Sn–Sr system are obtained by CALPHAD method. ► A hybrid approach of CALPHAD and first-principles calculations is recommended. - Abstract: A hybrid approach of CALPHAD and first-principles calculations was employed to perform a thermodynamic modeling of the Sn–Sr system. The experimental phase diagram and thermodynamic data available in the literature were critically reviewed. The enthalpies of formation for the 6 stoichiometric compounds (i.e. Sr 2 Sn, Sr 5 Sn 3 , SrSn, Sr 3 Sn 5 , SrSn 3 and SrSn 4 ) at 0 K were computed by means of first-principles calculations. These data were used as the experimental values in the optimization module PARROT in the subsequent CALPHAD assessment to provide thermodynamic parameters with sound physical meaning. A set of self-consistent thermodynamic parameters was finally obtained by considering reliable literature data and the first-principles computed results. Comprehensive comparisons between the calculated and measured quantities indicate that all the reliable experimental information can be satisfactorily accounted for by the present thermodynamic description.

Loop quantum cosmology (LQC) is very powerful to deal with the behavior of early universe. Moreover, the effective loop quantum cosmology gives a successful description of the universe in the semiclassical region. We consider the apparent horizon of the Friedmann-Robertson-Walker universe as a thermodynamical system and investigate the thermodynamics of LQC in the semiclassical region. The effective density and effective pressure in the modified Friedmann equation from LQC not only determine the evolution of the universe in LQC scenario but also are actually found to be the thermodynamic quantities. This result comes from the energy definition in cosmology (the Misner-Sharp gravitational energy) and is consistent with thermodynamic laws. We prove that within the framework of loop quantum cosmology, the elementary equation of equilibrium thermodynamics is still valid.

Informing Physics: Jacob Bekenstein and the Informational Turn in Theoretical Physics

Science.gov (United States)

Belfer, Israel

In his PhD dissertation in the early 1970s, the Mexican-Israeli theoretical physicist Jacob Bekenstein developed the thermodynamics of black holes using a generalized version of the second law of thermodynamics. This work made it possible for physicists to describe and analyze black holes using information-theoretical concepts. It also helped to transform information theory into a fundamental and foundational concept in theoretical physics. The story of Bekenstein's work—which was initially opposed by many scientists, including Stephen Hawking—highlights the transformation within physics towards an information-oriented scientific mode of theorizing. This "informational turn" amounted to a mild-mannered revolution within physics, revolutionary without being rebellious.

Thermodynamic data are needed for all kinds of simulations of materials processes. Thermodynamics determines the set of stable phases and also provides chemical potentials, compositions and driving forces for nucleation of new phases and phase transformations. Software to simulate materials properties needs accurate and consistent thermodynamic data to predict metastable states that occur during phase transformations. Due to long calculation times thermodynamic data are frequently pre-calculated into “lookup tables” to speed up calculations. This creates additional uncertainties as data must be interpolated or extrapolated and conditions may differ from those assumed for creating the lookup table. Speed and accuracy requires that thermodynamic software is fully parallelized and the Open-Calphad (OC) software is the first thermodynamic software supporting this feature. This paper gives a brief introduction to computational thermodynamics and introduces the basic features of the OC software and presents four different application examples to demonstrate its versatility.

Black hole chemistry: thermodynamics with Lambda

International Nuclear Information System (INIS)

Kubizňák, David; Mann, Robert B; Teo, Mae

2017-01-01

We review recent developments on the thermodynamics of black holes in extended phase space, where the cosmological constant is interpreted as thermodynamic pressure and treated as a thermodynamic variable in its own right. In this approach, the mass of the black hole is no longer regarded as internal energy, rather it is identified with the chemical enthalpy. This leads to an extended dictionary for black hole thermodynamic quantities; in particular a notion of thermodynamic volume emerges for a given black hole spacetime. This volume is conjectured to satisfy the reverse isoperimetric inequality—an inequality imposing a bound on the amount of entropy black hole can carry for a fixed thermodynamic volume. New thermodynamic phase transitions naturally emerge from these identifications. Namely, we show that black holes can be understood from the viewpoint of chemistry, in terms of concepts such as Van der Waals fluids, reentrant phase transitions, and triple points. We also review the recent attempts at extending the AdS/CFT dictionary in this setting, discuss the connections with horizon thermodynamics, applications to Lifshitz spacetimes, and outline possible future directions in this field.

New astrophysical school of thermodynamics. Space dynamics and gravitism

Energy Technology Data Exchange (ETDEWEB)

Much verified information has been accumulated in recent years which shows that many fundamental concepts involving classical physics, thermodynamics, astrophysics and the general theory of relativity are strongly coupled together. This evidence is employed in this paper to explain principles of the astrophysical school of thermodynamics; a growing revolutionary school which deduces thermodynamics, energy dissipation, and time anisotropies from the Newtonian and Einsteinian theories of gravitation and from the dynamics of radiation in 'unsaturable' (intercluster) space. Accordingly, the density of radiation and the dynamics of ('unsaturable') outer space affect all processes in the galactic media, in the solar system, in the magnetosphere and on Earth. The origin of all observed irreversibilities in nature - of time, of all time anisotropics, of energy dissipation, of T-violations in 'elementary particles', of retarded potentials in electrodynamics, of the biological clocks, and of biological arrows of time - is one; it is the radiation unsaturability of space. But, since this unsaturability and gravitation are interconnected, the origin of asymmetries, structure, and thermodynamics is explained within the framework of the Newtonian and Einsteinian theories of gravitation. The theory presented here forms a part of a general approach called gravitism, which unifies some other disciplinary studies in the natural sciences with a unified approach to gravitation and the theory of time.

Generalized Information Equilibrium Approaches to EEG Sleep Stage Discrimination

Directory of Open Access Journals (Sweden)

Todd Zorick

2016-01-01

Full Text Available Recent advances in neuroscience have raised the hypothesis that the underlying pattern of neuronal activation which results in electroencephalography (EEG signals is via power-law distributed neuronal avalanches, while EEG signals are nonstationary. Therefore, spectral analysis of EEG may miss many properties inherent in such signals. A complete understanding of such dynamical systems requires knowledge of the underlying nonequilibrium thermodynamics. In recent work by Fielitz and Borchardt (2011, 2014, the concept of information equilibrium (IE in information transfer processes has successfully characterized many different systems far from thermodynamic equilibrium. We utilized a publicly available database of polysomnogram EEG data from fourteen subjects with eight different one-minute tracings of sleep stage 2 and waking and an overlapping set of eleven subjects with eight different one-minute tracings of sleep stage 3. We applied principles of IE to model EEG as a system that transfers (equilibrates information from the time domain to scalp-recorded voltages. We find that waking consciousness is readily distinguished from sleep stages 2 and 3 by several differences in mean information transfer constants. Principles of IE applied to EEG may therefore prove to be useful in the study of changes in brain function more generally.

We address a long-standing problem of describing the thermodynamics of an accelerating black hole. We derive a standard first law of black hole thermodynamics, with the usual identification of entropy proportional to the area of the event horizon-even though the event horizon contains a conical singularity. This result not only extends the applicability of black hole thermodynamics to realms previously not anticipated, it also opens a possibility for studying novel properties of an important class of exact radiative solutions of Einstein equations describing accelerated objects. We discuss the thermodynamic volume, stability, and phase structure of these black holes.

Role of information systems in public health services.

The purpose of this review is to establish a conceptual framework on the role of information systems in public health care. Information is indispensable for effective management and development of health services and therefore considered as an important operational asset or resource. A Health Information System is mainly required to support management and operations at four levels: namely transactional and functional; operational control; management planning and control; and strategic planning. To provide the necessary information needs of users at these levels of management in the health care system, a structured information system coupled with appropriate information technology is required. Adequate and relevant information is needed regarding population characteristics, resources available and expended, output and outcome of health care activities. Additionally information needs to be reliable, accurate, timely, easily accessible and presented in a compact and meaningful form. With a well-planned health information system health authorities would be in a position to provide a quality, cost-effective and efficient health service for as many people as need it, optimal utilisation of resources and to maintain and improve the community's health status.

Thermodynamics of complexity and pattern manipulation

Garner, Andrew J. P.; Thompson, Jayne; Vedral, Vlatko; Gu, Mile

Many organisms capitalize on their ability to predict the environment to maximize available free energy and reinvest this energy to create new complex structures. This functionality relies on the manipulation of patterns—temporally ordered sequences of data. Here, we propose a framework to describe pattern manipulators—devices that convert thermodynamic work to patterns or vice versa—and use them to build a "pattern engine" that facilitates a thermodynamic cycle of pattern creation and consumption. We show that the least heat dissipation is achieved by the provably simplest devices, the ones that exhibit desired operational behavior while maintaining the least internal memory. We derive the ultimate limits of this heat dissipation and show that it is generally nonzero and connected with the pattern's intrinsic crypticity—a complexity theoretic quantity that captures the puzzling difference between the amount of information the pattern's past behavior reveals about its future and the amount one needs to communicate about this past to optimally predict the future.
