    A modern approach to relay co-ordination that takes advantage of the improved performance of modern protective relays and circuits was proposed. The proposed method dealt with a mixture of new and old equipment and was most useful when implemented using common spreadsheet software. The suggested approach justified reduced time margins for relay co-ordination in many difficult applications. Other established approaches were reviewed. A discussion of fixed and variable time margin allowances was presented. The formulation of an equation to determine the required upstream relay operating time was explained, with sample calculations. Relay performance standards and modern protective equipment were discussed. It was concluded that modern relays and circuit breakers are much more advanced than designs of the recent past. The method described allowed significant reductions in margins which enabled modern relays to operate faster. While calculations for the procedures were said to be tedious to perform by hand, they can be easily done with spreadsheet software. 10 refs., 4 figs.

    150 years ago, in 1866, Ernst Haeckel published a book in two volumes called "Generelle Morphologie der Organismen" (General Morphology of Organisms) in which he formulated his biogenetic law, famously stating that ontogeny recapitulates phylogeny. Here we describe Haeckel's original idea and follow its development in the thinking of two scientists inspired by Haeckel, Alexei Sewertzoff and Adolf Naef. Sewertzoff and Naef initially approached the problem of reformulating Haeckel's law in similar ways, and formulated comparable hypotheses at a purely descriptive level. But their theoretical viewpoints were crucially different. While Sewertzoff laid the foundations for a Darwinian evolutionary morphology and is regarded as a forerunner of the Modern Synthesis, Naef was one of the most important figures in 'idealistic morphology', usually seen as a type of anti-Darwinism. Both Naef and Sewertzoff aimed to revise Haeckel's biogenetic law and came to comparable conclusions at the empirical level. We end our review with a brief look at the present situation in which molecular data are used to test the "hour-glass model", which can be seen as a modern version of the biogenetic law.

    2013-01-01

    Optimization problems were and still are the focus of mathematics from antiquity to the present. Since the beginning of our civilization, the human race has had to confront numerous technological challenges, such as finding the optimal solution of various problems including control technologies, power sources construction, applications in economy, mechanical engineering and energy distribution amongst others. These examples encompass both ancient as well as modern technologies like the first electrical energy distribution network in USA etc. Some of the key principles formulated in the middle ages were done by Johannes Kepler (Problem of the wine barrels), Johan Bernoulli (brachystochrone problem), Leonhard Euler (Calculus of Variations), Lagrange (Principle multipliers), that were formulated primarily in the ancient world and are of a geometric nature. In the beginning of the modern era, works of L.V. Kantorovich and G.B. Dantzig (so-called linear programming) can be considered amongst others. This book disc...

    Aggregating formulations is a powerful approach for problems to take on tractable forms. Aggregation may lead to loss of information, i.e. the aggregated formulation may be an approximation of the original problem. In branch-and-bound context, aggregation can also complicate branching, e.g. when...... optimality cannot be guaranteed by branching on aggregated variables. We present a generic exact solution method to remedy the drawbacks of aggregation. It combines the original and aggregated formulations and applies Benders' decomposition. We apply the method to the Split Delivery Vehicle Routing Problem....

    Full Text Available This paper discusses development of modernization processes in the Russian industrial enterprises. The object of the current study is the JSC "Perm Company of petroleum machinery-producing industry". It has been manufacturing oilfield service products of various kinds. It is shown that the impact of modernization on the enterprise depends not only on the local effectiveness of selected solutions, but also on the overall strategy of sustainable development. Modernization is a strategic planning tool. Taking into account the need for a comprehensive approach to strategic development and modernization, the top five stages of the development strategy of the company were mentioned: 1 analysis of internal and external environment; 2 definition of the mission and goals; 3 choice of strategy and baseline scenarios; 4 development of basic strategy; 5 implementation of the strategy. At each stage, methods and tools for strategic planning, as well as the tools of modernization are defined. The relationship between modernization and development strategy of the company is shown. It was revealed that an integrated approach to the modernization and incremental implementation are the basics for the use of a hierarchical system of optimization models to describe the process of manufacturing company modernization. As the target model of the upper level, financial performance of the company is defined. This approach has the following advantages over the point upgrading - reducing the probability of omission of important limitations and ineffective use of resources during the transition to modernization of the company. Basing on the main strategic goals, main directions and tasks of modernization, which are integrated into the tree ends were formed. A thesis was substantiated that he essence of modernization lies in the continuity of mutually complex processes of improving all its directions.

    1995-12-31

    The increasing densities and reduced geographical spans of urban and industrial power systems call for the coordination of more stages of overcurrent protection up to increasingly high fault levels. Applying existing rules of relay coordination, especially for industrial power systems, may make achieving satisfactory coordination difficult. This paper proposes a modern approach to coordination which is able to take advantage of the improved performance of modern protective relays and circuit breakers. The proposed method can handle a mix of new and old equipment and is made most useful when implemented with commonly available spreadsheet software. The suggested approach justifies reduced time margins for relay coordination in many difficult applications. Example calculations are included to illustrate typical considerations for coordinating two digital protection relays where a vacuum circuit breaker is used to clear a downstream fault.

    Kang, Hyeon Tae; Sung, Chan Ho; Lee, Jae Ki

    2009-01-01

    Utilities have recently been debating the respective pros and cons of implementation of a multi-phase modernization during several normal outages versus a single major modernization implementation during a prolonged outage. We have studied these approaches and have been developing the basic design of NPPs I and C modernization since early 2008. As part of this study, analyses of the NPPs I and C systems were conducted and the need for upgrading the systems was raised. One of the primary concerns regarding the system modernization is a cost-benefit implementation, which will influence the modernization approach. From this viewpoint, the I and C modernization must consider economic factors such as I and C vendor cost, architecture engineering cost, installation cost, utility cost, and other transition costs such as training and procedure development. This paper presents a comparison study of economical aspects including cost evaluation between the aforementioned modernization implementations and suggests a solution for the I and C modernization approach.

    Compulsive gambling has received widespread attention in the last decade. Gambling has become the first non-chemical addiction, which went down to the section "Addiction and related disorders" of the modern DSM-V. The review considers non-pharmacological and pharmacological approaches to the treatment of gambling. Among non-drug approaches, cognitive-behavioral therapy and 12-step programs have gained the most popularity in the "Gamblers Anonymous" community. Among pharmacological approaches, three classes of drugs: antidepressants (mainly SSRIs), opiate antagonists (naltrexone and nalmefene) and mood stabilizers (valproate, lithium, topiramate) proved to be effective in treatment of gambling. No differences in the efficacy of the three classes of psychotropic drugs have been identified. Preliminary results for N-acetylcysteine and memantine cause optimism in terms of perspective.

    The classical control theory approach to the multivariate control problem is to decouple the system intentionally and to treat each loop independently. As a result, final control system design is limited in complexity by the available mathematical techniques limitation and it's control performance is insufficient in many cases. The modern control theory approach based on the state variables to the problem provides far more powerful methods and more design flexibility than the classical control theory approach by the new mathematical formulation about the problem. The state variable feedback in formulating as an optimal regulator is the most effective way to obtain the desired control performance. In this report, some results of optimal regulator application to High Temperature Gas Cooled Reactor (HTGR) are shown. (author)

    Surrogate fuel formulation has drawn significant interest due to its relevance towards understanding combustion properties of complex fuel mixtures. In this work, we present a novel approach for surrogate fuel formulation by matching target fuel functional groups, while minimizing the number of surrogate species. Five key functional groups; paraffinic CH, paraffinic CH, paraffinic CH, naphthenic CH–CH and aromatic C–CH groups in addition to structural information provided by the Branching Index (BI) were chosen as matching targets. Surrogates were developed for six FACE (Fuels for Advanced Combustion Engines) gasoline target fuels, namely FACE A, C, F, G, I and J. The five functional groups present in the fuels were qualitatively and quantitatively identified using high resolution H Nuclear Magnetic Resonance (NMR) spectroscopy. A further constraint was imposed in limiting the number of surrogate components to a maximum of two. This simplifies the process of surrogate formulation, facilitates surrogate testing, and significantly reduces the size and time involved in developing chemical kinetic models by reducing the number of thermochemical and kinetic parameters requiring estimation. Fewer species also reduces the computational expenses involved in simulating combustion in practical devices. The proposed surrogate formulation methodology is denoted as the Minimalist Functional Group (MFG) approach. The MFG surrogates were experimentally tested against their target fuels using Ignition Delay Times (IDT) measured in an Ignition Quality Tester (IQT), as specified by the standard ASTM D6890 methodology, and in a Rapid Compression Machine (RCM). Threshold Sooting Index (TSI) and Smoke Point (SP) measurements were also performed to determine the sooting propensities of the surrogates and target fuels. The results showed that MFG surrogates were able to reproduce the aforementioned combustion properties of the target FACE gasolines across a wide range of conditions

    2012-08-01

    Full Text Available In this paper, an integrated approach is proposed for non-recursive formulation of connection coefficients of different orthogonal functions in terms of a generic orthogonal function. The application of these coefficients arises when the product of two orthogonal basis functions are to be expressed in terms of single basis functions. Two significant advantages are achieved; one, the non-recursive formulations avoid memory and stack overflows in computer implementations; two, the integrated approach provides for digital hardware once-designed can be used for different functions. Computational savings achieved with the proposed non-recursive formulation vis-à-vis recursive formulation, reported in the literature so far, have been demonstrated using MATLAB PROFILER.

It outlines the multi-faceted approaches to a (or more than one modernity between and beyond Westernisation and Sinicisation as formulated in the twentieth century, be it in Republican China, Taiwan or the People's Republic, and how this is reflected in "Western" historiography on China. For China, (rearticulations of "alternatives" would open up the possibility for more than just one single, homogenising, culturalist-essentialist (and top-down defined "Chinese dream". Since discussions of modernity are always closely linked to the concerns of the present, shifts in global economy and politics might, in turn, also lead to new conceptions of what a "global modernity" (if such a single entity exists should mean and how the Chinese case might relate (or contribute to it.

    Currently marketed minoxidil formulations present inconveniences that range from a grease hard aspect they leave on the hair to more serious adverse reactions as scalp dryness and irritation. In this paper we propose a novel approach for minoxidil sulphate (MXS) delivery based on a solid effervescent formulation. The aim was to investigate whether the particle mechanical movement triggered by effervescence would lead to higher follicle accumulation. Preformulation studies using thermal, spectroscopic and morphological analysis demonstrated the compatibility between effervescent salts and the drug. The effervescent formulation demonstrated a 2.7-fold increase on MXS accumulation into hair follicles casts compared to the MXS solution (22.0±9.7μg/cm 2 versus 8.3±4.0μg/cm 2 ) and a significant drug increase (around 4-fold) in remaining skin (97.1±29.2μg/cm 2 ) compared to the drug solution (23.5±6.1μg/cm 2 ). The effervescent formulations demonstrated a prominent increase of drug permeation highly dependent on the effervescent mixture concentration in the formulation, confirming the hypothesis of effervescent reaction favoring drug penetration. Clinically, therapy effectiveness could be improved, increasing the administration interval, hence, patient compliance. More studies to investigate the follicular targeting potential and safety of new formulations are needed. Copyright © 2016 Elsevier B.V. All rights reserved.

  12. A new formulation of Stokes’ approach in determining the global gravimetric geoid

    Directory of Open Access Journals (Sweden)

    Wen-Bin Shen

    2013-08-01

    Full Text Available According to Stokes’ approach, given the gravity anomaly on the geoid as the boundary, a disturbing potential function satisfying some boundary conditions should be solved. The basic requirement is that the disturbing potential function should be harmonic in the region outside the geoid. However, since the normal gravity potential is not defined inside the reference ellipsoid (taking the WGS84 ellipsoid as an example, when the geoid is below the ellipsoidal surface, the disturbing potential function is not harmonic in the whole region outside the geoid, and is not defined on the whole geoid itself. These are theoretical difficulties in Stokes’ approach. To remove these difficulties from Stokes’ approach, this study provides a new formulation of Stokes’ approach. An inner ellipsoid with four fundamental parameters is chosen, two of which, the geocentric gravitational constant and the rotational angular velocity, coincide with the corresponding parameters of the WGS84 ellipsoid. The other two parameters, the semi-major axis and flattening, are different from the corresponding ones of the ellipsoid. Then, the normal gravity potential generated by the inner ellipsoid is determined, by requiring that it holds a constant on the surface of the inner ellipsoid or on the surface of the ellipsoid. With this new formulation, the disturbing potential function is harmonic in the whole region outside the geoid, and the difficulties in Stokes’ approach disappear. The new formulation proposed in this study is also adequate for analogous geodetic boundary-value problems.

    Plants have long been recognized for their therapeutic properties. For centuries, indigenous cultures around the world have used traditional herbal medicine to treat a myriad of maladies. By contrast, the rise of the modern pharmaceutical industry in the past century has been based on exploiting individual active compounds with precise modes of action. This surge has yielded highly effective drugs that are widely used in the clinic, including many plant natural products and analogues derived from these products, but has fallen short of delivering effective cures for complex human diseases with complicated causes, such as cancer, diabetes, autoimmune disorders and degenerative diseases. While the plant kingdom continues to serve as an important source for chemical entities supporting drug discovery, the rich traditions of herbal medicine developed by trial and error on human subjects over thousands of years contain invaluable biomedical information just waiting to be uncovered using modern scientific approaches. Here we provide an evolutionary and historical perspective on why plants are of particular significance as medicines for humans. We highlight several plant natural products that are either in the clinic or currently under active research and clinical development, with particular emphasis on their mechanisms of action. Recent efforts in developing modern multi-herb prescriptions through rigorous molecular-level investigations and standardized clinical trials are also discussed. Emerging technologies, such as genomics and synthetic biology, are enabling new ways for discovering and utilizing the medicinal properties of plants. We are entering an exciting era where the ancient wisdom distilled into the world's traditional herbal medicines can be reinterpreted and exploited through the lens of modern science.

    A review of "up to date" research findings leading to new concepts of the pharmaceutical formulations and their interactions has been presented. The rational approaches to the excipients choice as well as to their interactions with medicaments have been shown as a basis for modern modelling of pharmaceutical formulations. The importance of complexation, hydrogen bonding, ion-dipole, dipole-dipole and van der Waals attractions as the tools which can modify the physicochemical, pharmacological or pharmacokinetical behaviour of the medicaments has been emphasised. In vivo studies (carried out in healthy human subjects-volunteers, in beagle dogs, in rats etc.) and in vitro studies (on excised human skin, hairless mouse skin etc.) as well as studies of chemical stability and bioavailability serve also as a proof of these interactions. Therefore, excipients are important components of pharmaceutical formulations and they can take an active part in the improvement of the characteristics of formulations (but they may also reduce the effectiveness of some preparations). In this context, the so called active and inactive ingredients in pharmaceutical formulations are inexact, old and "out-of date". Their further use is only conventional. In conclusion, among the various modern techniques applied the combination of infrared spectroscopy and X-ray diffraction has been estimated as the most successful in proving the interactions between drugs and excipients. Finally, pharmaceutical formulations and their interactions have constituted a diverse and rapidly expanding field of Pharmacy (Pharmaceutical Technology, Pharmaceutical Industry and Pharmaceutical Sciences) which covers a wide range of numerical topics within an unified framework.

    Townsend, John S

    2012-01-01

    Using an innovative approach that students find both accessible and exciting, A Modern Approach to Quantum Mechanics, Second Edition lays out the foundations of quantum mechanics through the physics of intrinsic spin. Written to serve as the primary textbook for an upper-division course in quantum mechanics, Townsend's text gives professors and students a refreshing alternative to the old style of teaching, by allowing the basic physics of spin systems to drive the introduction of concepts such as Dirac notation, operators, eigenstates and eigenvalues, time evolution in quantum mechanics, and entanglement. Chapters 6 through 10 cover the more traditional subjects in wave mechanics-the Schrodinger equation in position space, the harmonic oscillator, orbital angular momentum, and central potentials-but they are motivated by the foundations developed in the earlier chapters. Students using this text will perceive wave mechanics as an important aspect of quantum mechanics, but not necessarily the core of the subj...

    Full Text Available Background: An increase in the awareness about the advantages of the traditional system of medicines has led to the commercialization of the formulations used for the treatments. Manufacture of these medicines to meet this increasing demand has resulted in a decline in their quality, primarily due to a lack of adequate regulations pertaining to this sector of medicine. Hence, it is necessary to come up with a systematic approach to develop well-designed methodologies for the standardization of polyherbal formulations which are used in traditional systems of medicine. Materials and Methods: Qurs-e-Hummaz formulations were prepared by a qualified “Hakim” (Unani medical practitioner of Faculty of Unani Medicine, Hamdard University, as per the formula and instruction given in National Formulary of Unani Medicine. Results: Various quality control parameters such as organoleptic evaluations (color, odor, taste, and consistency, physicochemical evaluations (loss on drying, disintegration time, moisture content, total ash, acid insoluble ash, water soluble ash, pH of 1 and 10% solution, extractive values, water soluble matter, alcohol-soluble matter, and total phenolic content and thin layer chromatography fingerprint profiling have been carried out in triplicate. The evaluation of contaminants such as heavy metals, aflatoxins, pesticide residues, and microbial contamination has also been carried out in the formulation. Conclusion: Help in maintaining the quality and batch to batch consistency of many important polyherbal formulations.

  20. Study of energy partitioning using a set of related explosive formulations

    Lieber, Mark; Foster, Joseph C.; Stewart, D. Scott

    2012-03-01

    Condensed phase high explosives convert potential energy stored in the electro-magnetic field structure of complex molecules to high power output during the detonation process. Historically, the explosive design problem has focused on intramolecular energy storage. The molecules of interest are derived via molecular synthesis providing near stoichiometric balance on the physical scale of the molecule. This approach provides prompt reactions based on transport physics at the molecular scale. Modern material design has evolved to approaches that employ intermolecular ingredients to alter the spatial and temporal distribution of energy release. State of the art continuum methods have been used to study this approach to the materials design. Cheetah has been used to produce data for a set of fictitious explosive formulations based on C-4 to study the partitioning of the available energy between internal and kinetic energy in the detonation. The equation of state information from Cheetah has been used in ALE3D to develop an understanding of the relationship between variations in the formulation parameters and the internal energy cycle in the products.

    2017-08-01

    The aim of the present work was to develop and optimize multiparticulate formulation viz. pellets of naproxen by employing QbD and risk assessment approach. Mixture design with extreme vertices was applied to the formulation with high loading of drug (about 90%) and extrusion-spheronization as a process for manufacturing pellets. Independent variables chosen were level of microcrystalline cellulose (MCC)-X 1 , polyvinylpyrrolidone K-90 (PVP K-90)-X 2 , croscarmellose sodium (CCS)-X 3 , and polacrilin potassium (PP)-X 4 . Dependent variables considered were disintegration time (DT)-Y 1 , sphericity-Y 2 , and percent drug release-Y 3 . The formulation was optimized based on the batches generated by MiniTab 17 software. The batch with maximum composite desirability (0.98) proved to be optimum. From the evaluation of design batches, it was observed that, even in low variation, the excipients affect the pelletization property of the blend and also the final drug release. In conclusion, pellets with high drug loading can be effectively manufactured and optimized systematically using QbD approach.

    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...

  8. Does Johnson's Prescriptive Approach Still Have a Role to Play in Modern-Day Dictionaries?

    ABSTRACT: Samuel Johnson's dictionary (1755 confirmed both the status of dictionaries as authoritative sources of (linguistic knowledge and the prescriptive approach in lexicography. This approach prevailed for a long time. During the last decades the descriptive approach came to the fore, aptly supported by the increased reliance on lexicographic corpora. Modern-day lexicography has also witnessed the introduction of a third approach, i.e. the proscriptive approach, which includes features of both the prescriptive and the descriptive approach. This article investigates the occurrence of the prescriptive, descriptive and proscriptive approaches in modern-day dictionaries. A distinction is made between dictionaries focusing on language for general purposes and dictionaries focusing on languages for special purposes. It is shown that users rely on dictionaries as prescriptive reference sources and expect lexicographers to provide them with an answer to the specific question that prompted the dictionary consultation process. It is argued that knowledgeable dictionary users must be able to achieve an unambiguous retrieval of information and must be able to rely on the dictionary to satisfy their specific cognitive or communicative needs. Here the proscriptive approach plays an important role.

  9. Modern Adaptive Analytics Approach to Lowering Seismic Network Detection Thresholds

    Science.gov (United States)

    Johnson, C. E.

    2017-12-01

    Modern seismic networks present a number of challenges, but perhaps most notably are those related to 1) extreme variation in station density, 2) temporal variation in station availability, and 3) the need to achieve detectability for much smaller events of strategic importance. The first of these has been reasonably addressed in the development of modern seismic associators, such as GLASS 3.0 by the USGS/NEIC, though some work still remains to be done in this area. However, the latter two challenges demand special attention. Station availability is impacted by weather, equipment failure or the adding or removing of stations, and while thresholds have been pushed to increasingly smaller magnitudes, new algorithms are needed to achieve even lower thresholds. Station availability can be addressed by a modern, adaptive architecture that maintains specified performance envelopes using adaptive analytics coupled with complexity theory. Finally, detection thresholds can be lowered using a novel approach that tightly couples waveform analytics with the event detection and association processes based on a principled repicking algorithm that uses particle realignment for enhanced phase discrimination.

  10. Modern canonical quantum general relativity

    CERN Document Server

    Thiemann, Thomas

    2007-01-01

    This is an introduction to the by now fifteen years old research field of canonical quantum general relativity, sometimes called "loop quantum gravity". The term "modern" in the title refers to the fact that the quantum theory is based on formulating classical general relativity as a theory of connections rather than metrics as compared to in original version due to Arnowitt, Deser and Misner. Canonical quantum general relativity is an attempt to define a mathematically rigorous, non-perturbative, background independent theory of Lorentzian quantum gravity in four spacetime dimensions in the continuum. The approach is minimal in that one simply analyzes the logical consequences of combining the principles of general relativity with the principles of quantum mechanics. The requirement to preserve background independence has lead to new, fascinating mathematical structures which one does not see in perturbative approaches, e.g. a fundamental discreteness of spacetime seems to be a prediction of the theory provi...

    Two beneficial Pseudomonas isolates selected from rhizosphere of abundant weed - couch-grass Elytrigia repens L. Nevski have been found to have biocontrol activity. An adequate biocontrol effect requires high yield and long stability of the bacterial preparation [1], which could be achieved by an effective and stable formulation. This study was aimed to test various approaches to dry formulation techniques for Pseudomonas- based preparations. To reach this goal, two drying formulation techniques have been tested: the first one, spray drying and the second, low-temperature contact-convective drying in fluidized bed. The optimal temperature parameters for each technique were estimated. Main merits of the selected approach to dry technique are high yield, moderate specific energy expenditures per 1 kg of evaporated moisture, minimal time of contact of the drying product with drying agent. The technological process for dry formulation included the following stages: the obtaining of cell liquids, the low-temperature concentrating and the subsequent drying of a concentrate. The preliminary technological stages consist in cultivation of the rhizobacteria cultures and concentrating the cell liquids. The following requirements for cultivation regime in laboratory conditions were proposed: optimal temperatures are 26-28°С in 3 days, concentration of viable cells in cell liquid makes 1010-1011 cell/g of absolutely dry substance (ADS). For concentrating the cell liquids the method of a vacuum evaporation, which preserves both rhizobacteria cells and the secondary metabolites of cell liquid, has been used. The process of concentrating was conducted at the minimum possible temperature, i.e. not above 30-33°С. In this case the concentration of viable cells has decreased up to 109-1010 cell/g of ADS. For spray drying the laboratory up-dated drier BUCHI 190, intended for the drying of thermolabile products, was used. The temperatures of an in- and outcoming air did not exceed

    Linking marine epizootics to a specific aetiology is notoriously difficult. Recent diagnostic successes show that marine disease diagnosis requires both modern, cutting-edge technology (e.g. metagenomics, quantitative real-time PCR) and more classic methods (e.g. transect surveys, histopathology and cell culture). Here, we discuss how this combination of traditional and modern approaches is necessary for rapid and accurate identification of marine diseases, and emphasize how sole reliance on any one technology or technique may lead disease investigations astray. We present diagnostic approaches at different scales, from the macro (environment, community, population and organismal scales) to the micro (tissue, organ, cell and genomic scales). We use disease case studies from a broad range of taxa to illustrate diagnostic successes from combining traditional and modern diagnostic methods. Finally, we recognize the need for increased capacity of centralized databases, networks, data repositories and contingency plans for diagnosis and management of marine disease.

    Full Text Available Globalized development strategies in industry are currently focused on developing intelligent manufacturing concepts called Industry 4.0. Companies around the world will be forced to adopt this concept, especially in terms of maintaining competitiveness. One of the most serious obstacles of developing the concept of intelligent production is physical and moral obsolescence of the manufacturing base in general. Despite the fact that companies have historically renewed their manufacturing base, automated and robotized manufacturing processes and systems, nowadays highly current question of determining the form and timing of further modernization and renewal of the manufacturing base for intelligent production purposes. The authors present a model to determine optimal time to start upgrading and renewing the production base based on formulating and comparing costs of means of production throughout their lifecycle, including consideration of their moral obsolescence.

    them or who posed a threat to others, or else commissioned them to the government hospital. Thus, the final responsibility for mental patients was imposed on the modern Western medical team, because the district commissioners sent them to the police and the police sent them to the government mental hospital. Most educated people and government personnel in the colonial era thought modern Western psychiatry circles were responsible for mental patient management, and the Japanese empire enacted mental-healthrelated laws and made efforts to secure funds for the establishment of mental hospitals. As the literature at that time also show the position of the modern Western medical circle, their ambivalent attitude to mental patients must also be clarified to interpret the modern approach to treating mental patients in colonial Chosun. In this context, a research on historical figures in Japanese psychiatry, a study on the specific treatment methods used by the modern Western psychiatric team in the colonial era and their effects, and the extension of the subject period for such researches are suggested.

    Full Text Available In the article the modern tendencies of using integrative approach to organizing art teachers’ instrumental and performing training. The concept “integration” is singled out; it is defined as the process of recovery, replenishment, combining previously isolated parts; moving of the system to a great organic integrity. It is disclosed that the integration means considering multidimensionality of element features which are being integrated while accumulating quantitative features and emerging a new quality and individual features of integral elements are saved. It is proved that integrating is interrelation of art varieties in the process of their aesthetic and educational impact on pupils that is the whole perception of a work (its content and its emotional, rational, ethical and aesthetic form in the unity of tasks of developing artistic and aesthetic senses, thoughts, tastes and pupils’ ideals. It is thought that integration in art pedagogy is held at three levels: internal artistic and aesthetic synthesis of various arts organically combined with students creative activity; interdisciplinary humanistic synthesis of the arts, the native language, literature, and folklore; looking for semantic blocks, images, concepts that have universal meaning, which, entering all spheres of human consciousness, such as science and mathematics, seamlessly combining them into a coherent system. It is noted that the most efficient approach is appeal to the learning subjects of Humanities cycle – music, literature and art. It is concluded that designing of training should be started with the analyzing prospective art teacher’s activity. It should be understood what the teacher has to do, not in general formulation, but at the level of actions and operations.

    2011-12-01

    Mineralogy has traditionally been a primary component in undergraduate geoscience curriculum. In recent years, there has been a trend in which mineralogy and petrology have been combined into Earth Materials courses. This is unfortunate as these disciplines each have much to offer students, and content once considered essential is eliminated out of necessity. Mineralogy is still fundamental to students' understanding of the Earth and Earth processes. Using a modern approach to time-honored concepts, I teach a quarter-long Introductory Mineralogy class offered through the Scripps Institution of Oceanography at the University of California, San Diego. Student evaluations of this course unequivocally indicate a high degree of learning and interest in the material, confirming that mineralogy continues to be a valuable class into the 21st century. While much of the content remains similar to what has been taught over the last century, my strategy involves a well-balanced approach to old and new. The first third of the course is background including the relevance of mineralogy, crystal chemistry, and crystallography; the second third of the course is systematic mineralogy using the Dana system; the last third of the course is devoted to understanding optical mineralogy, using modern analytical equipment such as XRD and SEM, and learning to use the petrographic microscope. Throughout the quarter, a strong emphasis is placed on the importance of hand-sample identification. Field work, traditionally not emphasized in mineralogy courses, has been re-introduced to the curriculum. I use modern technology to facilitate and support student learning. A lecture-based approach is employed with carefully crafted and organized PowerPoint presentations. PowerPoint lectures can be effective and highly engaging. The key is to ensure that the lectures are not overly reliant on text, instead relying on diagrams, charts, photos, and embedded media such as 3-D animations (ex. to teach

DF-loaded ethosomal formulations were prepared using 4 × 5 full-factorial design with phosphatidylcholine:cholesterol (PC:CH) ratios ranging between 50:50 and 90:10, and ethanol concentration ranging between 0% and 30% as formulation variables. These formulations were characterized in terms of physicochemical properties and skin permeation kinetics. The interaction of formulation variables had a significant effect on both physicochemical properties and permeation kinetics. The results of multivariate regression analysis illustrated that vesicle size and elasticity of ethosomes were the dominating physicochemical properties affecting skin permeation, and could be suitably controlled by manipulation of formulation variables to optimize the formulation and enhance the skin permeation of DF-loaded ethosomes. The optimized formulation had ethanol concentration of 22.9% and PC:CH ratio of 88.4:11.6, with vesicle size of 144 ± 5 nm, zeta potential of -23.0 ± 3.76 mV, elasticity of 2.48 ± 0.75 and entrapment efficiency of 71 ± 4%. Permeation flux for the optimized formulation was 12.9 ± 1.0 µg/h cm(2), which was significantly higher than the drug-loaded conventional liposome, ethanolic or aqueous solution. The in vivo study indicated that optimized ethosomal hydrogel exhibited enhanced anti-inflammatory activity compared with liposomal and plain drug hydrogel formulations.

  5. Being a Modern Human: essentialist and hierarchical approaches to the emergence of 'modern human behaviour'

    Full Text Available The emergence of the modern human mind and modern human behaviour is a prominent issue in palaeolithic archaeology. The consensus has been that modernity, understood in terms of increased rates of innovation and the emergence of symbolism, is enabled by a heritable neurophysiology unique to Homo sapiens. This consensus is characterised as biological essentialist in that it understands modernity as genotypically specified and unique to Homo sapiens. 'Archaic' hominins such as the Neanderthals are understood to have lacked the modern neuroanatomical genotype and therefore to have been innately incapable of modern cognition and behaviour. The biological-essentialist programme, however, is facing a serious challenge as evidence for innovation and symbolism is found in the archaeological records of the Eurasian Middle Palaeolithic and the African Middle Stone Age. An alternative programme is emerging that understands modern human behaviour as an emergent property of social, demographic and ecological dynamics. It is argued that this programme is currently inadequate since it cannot explain the emergence of symbolically charged material culture and relies on inexorable long-term population growth. It is suggested here that the problem is better understood in terms of hierarchy theory, a body of ideas concerned with systems organised on multiple scales. Palaeolithic behaviour is reconceptualised as social practice emerging from a multi-scale knowledge system. It is shown that enhancements in the rate at which knowledgeable practices disseminate through social fields – the social transmission of knowledge - will have the effect of increasing the likelihood that novel practices will be incorporated into long-term structuring principles and thus become persistent practices. They will also effect a scalar convergence of domains of knowledgeability such that technical practices become incorporated into the construction of personhood as meaningful or

  9. Modern Urban Naming Practices: Strategic Approaches and Practical Solutions

    Directory of Open Access Journals (Sweden)

    Marina V. Golomidova

    2017-11-01

    Full Text Available The article looks at the problems of the naming of municipal facilities. The author analyzes the existing policy in assigning new names and renaming urban sites, describes the current strategic approaches to urban naming and proposes a new strategy based on congruity with the holistic image of the city. The current approaches to urban naming mark the predominating interest in the historical and cultural heritage of cities as a valuable source for the toponymic nomination shared both by native and foreign experts. However, this commitment to the past may run counter to the modern arrangement and perception of the urban space, as well as impede the city development prospects. From the standpoint of modern area marketing, names of urban sites are regarded as an information and communication resource highly relevant to the city image formation and promotion. In the author’s view, the benefits of adopting a new strategy may also resonate with the concept of “urbanonymic construction,” which is understood as sustainable and streamlined management policy aimed at the progressive implementation of long-term programs for individual urban site names consistency. The urbanonymic construction involves a normative, regulatory aspect; formation of the holistic city image that builds on its resource base, the symbolic capital, and the development strategy; definition of key characteristics of the city image which are most relevant to its positioning; identification of principal nominative themes for verbal representation of the city image; use of naming technologies to ensure the relevance of the name’s implications; testing and expert evaluation of new names. Drawing on domestic and foreign expertise in the same study field, a number of practical solutions for the creation of new urbanonyms are described.

    Full Text Available Today, viral marketing is one of the most effective forms of marketing and it can be used to raise awareness about the product/service of a specific company. This type of marketing thrives in a modern environment, where final users (buyers/clients dominate by spreading messages within themselves. Boosted by the advantages that modern technology brings, viral marketing is booming in the online world. For the first time, small brands have a chance to make their appearance in the global market ad challenge the dominating position of the historically top brands. All they need is content that draws attention and modern, digital culture will help spread their message. Viral marketing is the future. And with the growth of social media and other channels, marketing managers need to be careful, because it is a thin line between a good and a bad (backfired viral campaign.

  11. A Decentralized Approach to the Formulation of Hypotheses: A Hierarchical Structural Model for a Prion Self-Assembled System

    Wang, Mingyang; Zhang, Feifei; Song, Chao; Shi, Pengfei; Zhu, Jin

    2016-07-01

    Innovation in hypotheses is a key transformative driver for scientific development. The conventional centralized hypothesis formulation approach, where a dominant hypothesis is typically derived from a primary phenomenon, can, inevitably, impose restriction on the range of conceivable experiments and legitimate hypotheses, and ultimately impede understanding of the system of interest. We report herein the proposal of a decentralized approach for the formulation of hypotheses, through initial preconception-free phenomenon accumulation and subsequent reticular logical reasoning processes. The two-step approach can provide an unbiased, panoramic view of the system and as such should enable the generation of a set of more coherent and therefore plausible hypotheses. As a proof-of-concept demonstration of the utility of this open-ended approach, a hierarchical model has been developed for a prion self-assembled system, allowing insight into hitherto elusive static and dynamic features associated with this intriguing structure.

    2018-06-01

    Hard tablets and capsules for oral drug delivery cause problems for people experiencing dysphagia. This work describes the formulation and properties of a gelatin based, self-preserved, and soft chewable tablet as an alternative and novel drug delivery format. Gelatin (8.8-10% in 24.7-29% water) constituted the matrix of the soft, semi-solid tablets. Three different pharmaceuticals (Ibuprofen 10%, Acetaminophen 15%, and Meloxicam 1.5%) were tested in this formulation. Microbial stability was controlled by lowering the water activity with a mixture of sorbitol and xylitol (45.6-55%). Rheological properties were tested applying small strain oscillation measurements. Taste masking of ibuprofen soft-chew tablets was achieved by keeping the ibuprofen insoluble at pH 4.5 and keeping the processing temperature below the crystalline-to-amorphous transition temperature. Soft-chew formulations showed good stability for all three pharmaceuticals (up to 24 months), and the ibuprofen containing formulation exhibited comparable dissolution to a standard oral tablet as well as good microbial stability. The rheological properties of the ibuprofen/gelatin formulation had the fingerprint of a true gelatin gel, albeit higher moduli, and melting temperature. The results suggest that easy-to-swallow and well taste-masked soft chewable tablet formulations with extended shelf life are within reach for several active pharmaceutical ingredients (APIs).

  14. Approaches to the History of Patients: From the Ancient World to Early Modern Europe.

    Stolberg, Michael

    2016-01-01

    This chapter looks from an early modernist's perspective at some of the major questions and methodological issues that writing the history of patients in the ancient world shares with similar work on Patientengeschichte in medieval and early modern Europe. It addresses, in particular, the problem of finding adequate sources that give access to the patients' experience of illness and medicine and highlights the potential as well as the limitations of using physicians' case histories for that purpose. It discusses the doctor-patient relationship as it emerges from these sources, and the impact of the patient's point of view on learned medical theory and practice. In conclusion, it pleads for a cautious and nuanced approach to the controversial issue of retrospective diagnosis, recommending that historians consistently ask in which contexts and in what way the application of modern diagnostic labels to pre-modern accounts of illness can truly contribute to a better historical understanding rather than distort it.

    Full Text Available Most recently, the concept of business documents has started to play double role. On one hand, a business document (word processing text or calculation sheet can be used as specification tool, on the other hand the business document is an immanent constituent of business processes, thereby essential component of business Information Systems. The recent tendency is that the majority of documents and their contents within business Information Systems remain in semi-structured format and a lesser part of documents is transformed into schemas of structured databases. In order to keep the emerging situation in hand, we suggest the creation (1 a theoretical framework for modeling business Information Systems; (2 and a design method for practical application based on the theoretical model that provides the structuring principles. The modeling approach that focuses on documents and their interrelationships with business processes assists in perceiving the activities of modern Information Systems.

    2002-01-01

    The PEBBED technique provides a foundation for equilibrium fuel cycle analysis and optimization in pebble-bed cores in which the fuel elements are continuously flowing and, if desired, recirculating. In addition to the modern analysis techniques used in or being developed for the code, PEBBED incorporates a novel nuclide-mixing algorithm that allows for sophisticated recirculation patterns using a matrix generated from basic core parameters. Derived from a simple partitioning of the pebble flow, the elements of the recirculation matrix are used to compute the spatially averaged density of each nuclide at the entry plane from the nuclide densities of pebbles emerging from the discharge conus. The order of the recirculation matrix is a function of the flexibility and sophistication of the fuel handling mechanism. This formulation for coupling pebble flow and neutronics enables core design and fuel cycle optimization to be performed by the manipulation of a few key core parameters. The formulation is amenable to modern optimization techniques. (author)

    Due to concern and debate in the epilepsy medical community and to the current interest of the US Food and Drug Administration (FDA) in revising approaches to the approval of generic drugs, the FDA is currently supporting ongoing bioequivalence studies of antiepileptic drugs, the EQUIGEN studies. During the design of these crossover studies, the researchers could not find commercial or non-commercial statistical software that quickly allowed computation of sample sizes for their designs, particularly software implementing the FDA requirement of using random-effects linear models for the analyses of bioequivalence studies. This article presents tables for sample-size evaluations of average bioequivalence studies based on the two crossover designs used in the EQUIGEN studies: the four-period, two-sequence, two-formulation design, and the six-period, three-sequence, three-formulation design. Sample-size computations assume that random-effects linear models are used in bioequivalence analyses with crossover designs. Random-effects linear models have been traditionally viewed by many pharmacologists and clinical researchers as just mathematical devices to analyze repeated-measures data. In contrast, a modern view of these models attributes an important mathematical role in theoretical formulations in personalized medicine to them, because these models not only have parameters that represent average patients, but also have parameters that represent individual patients. Moreover, the notation and language of random-effects linear models have evolved over the years. Thus, another goal of this article is to provide a presentation of the statistical modeling of data from bioequivalence studies that highlights the modern view of these models, with special emphasis on power analyses and sample-size computations.

    The present work was aimed to develop an antiseptic cream formulation of Indian basil oil utilizing hydrophilic-lipophilic balance approach. In order to determine the required-hydrophilic lipophilic balance (rHLB) of basil oil, emulsions of basil oil were prepared by phase inversion temperature technique using water, Tween 80, and Span 80. Formulated emulsions were assessed for creaming (BE9; 9.8, BE10; 10.2), droplet size (BE18; 3.22 ± 0.09 μ m), and turbidity (BE18; 86.12 ± 2.1%). To ensure correctness of the applied methodology, rHLB of light liquid paraffin was also determined. After rHLB determination, basil oil creams were prepared with two different combinations of surfactants, namely, GMS : Tween 80 (1 : 3.45) and SLS : GMS (1 : 3.68), and evaluated for in vitro antimicrobial activity, skin irritation test, viscosity and consistency. The rHLB of basil oil and light liquid paraffin were found to be 13.36 ± 0.36 and 11.5 ± 0.35, respectively. Viscosity, and consistency parameters of cream was found to be consistent over 90 days. Cream formulations showed net zone of growth inhibition in the range of 5.0-11.3 mm against bacteria and 4.3-7.6 mm against fungi. Primary irritation index was found to be between 0.38 and1.05. Conclusively stable, consistent, non-irritant, enriched antiseptic basil oil cream formulations were developed utilizing HLB approach.

  19. Current Approaches for Control Room I and C Modernization

    International Nuclear Information System (INIS)

    Lopez, Alberto; Jimenez, Alfonso

    2002-01-01

    In general, instrumentation and control (I and C) systems for nuclear power plants were made using analogic systems and relays, since this was the only technology available by the time these systems were designed. This fact impacts on the operational and maintenance capabilities required to these systems. For this reason, nuclear power plants are facing nowadays two challenges: on one hand, the obsolescence of these systems contributes to the increase in the operation and maintenance costs - due to the difficulties for getting spare parts and support from the system vendors -. On the other hand, there has been an increase in the utilities competitiveness due to the electric power market liberalization. All this, of course, along with the commitment to maintain the current safety levels and meet the new requirements and standards that may arise in the near future. The application of current technologies, especially digital technology, solves the obsolescence problems and allows for a more functional and updated human-machine interface. Nevertheless, the cost associated to these modifications makes it necessary to develop strategies to determine which systems need to be modified and how to implement modifications effectively, so that these systems can work jointly with others using different technologies. Other issues inherent to digital technology must be considered, such as verification and validation of the software and of the human-machine interface, which are required for its licensing. This presentation describes the current approaches for I and C modernization, the main reasons, technologies and implementation plans, focusing on the control room and on the impact on operations. The main issues to be considered for developing a specific modernization plan are analysed. The goals and status of the 'Feasibility Study of the Control Room I and C Modernization' are described. This study is currently being developed by Endesa, Iberdrola and Tecnatom, and is included

    Grujic, P. V.

    Development of the concept of fractal cosmos after Anaxagoras has been followed up to the present. It is shown how the concept reappeared in the early Renaissance as a vague idea and subsequently took up a concrete formulation at the beginning of the 20-eth century. The modern cosmology state of affairs has been considered in view of the fractal paradigm and the current disputes and controversies discussed. It is argued that the concept of the hierarchical cosmos is still alive and might become an essential ingredient within the modern view of the universe.

  2. Effectiveness of a consistently formulated diffusion-synthetic acceleration differencing approach

    International Nuclear Information System (INIS)

    Khalil, H.

    1988-01-01

    A consistently formulated differencing approach is applied to the diffusion-synthetic acceleration of discrete ordinates calculations based on various spatial differencing schemes. The diffusion ''coupling'' equations derived for each scheme are contrasted to conventional coupling relations and are shown to permit derivation of either point- or box-centered diffusion difference equations. The resulting difference equations are shown to be mathematically equivalent, in slab geometry, to equations derived by applying Larsen's four-step procedure to the S/sub 2/ equations. Fourier stability analysis of the acceleration method applied to slab model problems is used to demonstrate that, for any S/sub n/ differencing scheme (a) the upper bound on the spectral radius of the method occurs in the fine-mesh limit and equals that of the spatially continuous case (0.22466), and (b) the spectral radius decreases with increasing mesh size to an asymptotic value <0.13135. This model problem performance is somewhat superior to that of Larsen's approach, for which the spectral radius is bounded by 0.25 in the wide-mesh limit. Numerical results of multidimensional, heterogeneous, scattering-dominated problems are also presented to demonstrate the rapid convergence of accelerated discrete ordinates calculations using various spatial differencing schemes

  4. Modern Western Concepts of Philosophy of Education

    K. A. Ivanova

    2017-08-01

    Full Text Available The philosophy of education is represented by a wide range of concepts and approaches. The basic concepts of the philosophy of education can be divided into 4 groups according to the «pure» philosophical systems: realism, idealism, pragmatism, existentialism. Among the goals of the philosophy of education as an independent science are: stimulation, analysis, ordering, research. The delineation of the concept of education and the notion of school education are an important aspect in formulating the goals of the philosophy of education. A significant place in the process of finding and setting the goals of the philosophy of education is occupied by an alternative: discipline of mind or discipline of knowledge? It is worth paying attention to the goals of the modern Western philosophy of education: training for the formation of character, training for personal growth and success, training for the development and refinement of aesthetic predispositions, etc. Within the frameworks of the American philosophy of education, three main directions were formed: empiricism, rationalism, naturalism. According to the approach of the empiricists, education is the main factor, influencing human existence, which stimulates human activity, forms the person’s abilities and character. Rationalists introduced the idea of «self-alienation» as the most important for the philosophy of education. «Self-alienation» is a transition of a student from one stage of training to another one under the supervision of a teacher, when human mind becomes an object of his own attention. At the last stage of the student’s intellectual development, discovery of universals, laws and principles takes place. According to naturalists’ concept, the conclusions of scientific study of nature should be understood not as a testimony of truth, but as working hypotheses for further investigation. Scientific discoveries should be discoveries for education. Modern educational systems

    D'Ottavio, Michele; Dozio, Lorenzo; Vescovini, Riccardo; Polit, Olivier

    2018-01-01

    This paper extends to composite plates including piezoelectric plies the variable kinematics plate modeling approach called Sublaminate Generalized Unified Formulation (SGUF). Two-dimensional plate equations are obtained upon defining a priori the through-thickness distribution of the displacement field and electric potential. According to SGUF, independent approximations can be adopted for the four components of these generalized displacements: an Equivalent Single Layer (ESL) or Layer-Wise (LW) description over an arbitrary group of plies constituting the composite plate (the sublaminate) and the polynomial order employed in each sublaminate. The solution of the two-dimensional equations is sought in weak form by means of a Ritz method. In this work, boundary functions are used in conjunction with the domain approximation expressed by an orthogonal basis spanned by Legendre polynomials. The proposed computational tool is capable to represent electroded surfaces with equipotentiality conditions. Free-vibration problems as well as static problems involving actuator and sensor configurations are addressed. Two case studies are presented, which demonstrate the high accuracy of the proposed Ritz-SGUF approach. A model assessment is proposed for showcasing to which extent the SGUF approach allows a reduction of the number of unknowns with a controlled impact on the accuracy of the result.

    Full Text Available The aim of the article is to justify methods, techniques and key indicators for diagnosing the effectiveness of the implementation of the enterprise strategic development, to highlight the conceptual approaches to conducting diagnosis of the effectiveness of the strategy implementation. Modern approaches to the concept of “diagnosis” have been analyzed and the author’s vision of diagnosing the effectiveness of the strategy implementation in the context of the strategic management accounting has been suggested. The place and role of diagnosis in the system of enterprise strategic management have been substantiated. The methodical approach to determining the effectiveness of the implementation of the enterprise strategy comprising four stages has been proposed. As part of the approach there suggested formation of a number of targets characterizing a certain list of enterprise strategies allowing to conduct integral evaluation of each of the strategies and on the basis of these indicators to obtain the aggregate integral index of the level of the strategy implementation. However, unlike the existing methods, it is proposed to compare not only actual and planned levels of the indicators, but also determine what level of the strategy implementation corresponds to each monetary unit spent on the implementation of the strategy

    This textbook provides a unified and self-contained presentation of the main approaches to and ideas of mathematical statistics. It collects the basic mathematical ideas and tools needed as a basis for more serious studies or even independent research in statistics. The majority of existing textbooks in mathematical statistics follow the classical asymptotic framework. Yet, as modern statistics has changed rapidly in recent years, new methods and approaches have appeared. The emphasis is on finite sample behavior, large parameter dimensions, and model misspecifications. The present book provides a fully self-contained introduction to the world of modern mathematical statistics, collecting the basic knowledge, concepts and findings needed for doing further research in the modern theoretical and applied statistics. This textbook is primarily intended for graduate and postdoc students and young researchers who are interested in modern statistical methods.

  10. Sustainable Development, Architecture and Modernism: Aspects of an Ongoing Controversy

    Directory of Open Access Journals (Sweden)

    Han Vandevyvere

    2014-10-01

    Full Text Available In some discourses on sustainability, modernism in architecture is blamed for its technocratic beliefs that supposedly generated a lot of the social and environmental problems the world is facing today. At the same time, many architectural critics seem to be convinced that the present call for sustainability with its “green buildings”, is but another screen behind which well-known old power structures hide. In this paper, we react to these viewpoints in different ways. First we clarify the issues that are haunting current architectural discourses by unraveling the logics behind the viewpoints of the critics of the “environmental doctrine” on the one hand and the technical environmentalists on the other hand. We will offer, secondly, a new framing to these debates by relying upon the modal sphere theory of the Dutch philosopher Herman Dooyeweerd. This new framing will allow us to reconnect, thirdly, with the discourse of modernism, which, we will argue, is all too often conflated with a technocratic paradigm—a partial, incomplete and even misleading representation. In conclusion, we present a different framing of modernism, which allows understanding of it as a multilayered and multifaceted response to the challenges of modernity, a response that formulated a series of ideals that are not so far removed from the ideals formulated today by many advocates of sustainability. We are, thus, suggesting that the sustainability discourse should be conceived as a more mature and revised version of the paradigm of modernism, rather than its absolute counterpoint.

  11. From Hippocrates to modern medicine.

    Science.gov (United States)

    Orfanos, C E

    2007-07-01

    Hippocrates was the first to introduce the concept of 'physis' and to transform hieratic or theocratic medicine into rational medicine. The overall construction of the Asclepieion on Kos clearly indicates that he and his school followed a holistic concept, combining scientific thought with drug therapy, diet schedules, and physical and mental exercise, also asking for God's help. Hippocrates also formulated the first standards and ethical rules to be followed in medical profession, which are still valid today. The knowledge of Graeco-Roman medicine has been transferred by Arab scholars into the West, whereas renaissance, urbanization, and industrialisation have changed its face over the centuries. With the entrance of molecular technology and economy, modern medicine now faces the risk of becoming itself industrialized. Correct use of new scientific knowledge, individualized management with a Hippocratic holistic approach and compassionate sympathy for the patient who suffers, should be considered in the years to come for maintaining the level of medical profession. The venue of our European Congress in Rhodes is very close to Kos, another historic Aegean island, the place where Hippocrates has given the first professional standards in European medicine and in medicine in general. They were established 2600 years ago and are still valid today.(1,2) If one draws a red line and marks some cornerstones of the evolution that has taken place in medicine over the past centuries, it is evident that these first rules formulated by Hippocrates and his school also reveal the future responsibilities for our profession and make them better recognizable and more conclusive.

  12. Modern and Unconventional Approaches to Karst Hydrogeology

    Science.gov (United States)

    Sukop, M. C.

    2017-12-01

    Karst hydrogeology is frequently approached from a hydrograph/statistical perspective where precipitation/recharge inputs are converted to output hydrographs and the conversion process reflects the hydrology of the system. Karst catchments show hydrological response to short-term meteorological events and to long-term variation of large-scale atmospheric circulation. Modern approaches to analysis of these data include, for example, multiresolution wavelet techniques applied to understand relations between karst discharge and climate fields. Much less effort has been directed towards direct simulation of flow fields and transport phenomena in karst settings. This is primarily due to the lack of information on the detailed physical geometry of most karst systems. New mapping, sampling, and modeling techniques are beginning to enable direct simulation of flow and transport. A Conduit Flow Process (CFP) add-on to the USGS ModFlow model became available in 2007. FEFLOW and similar models are able to represent flows in individual conduits. Lattice Boltzmann models have also been applied to flow modeling in karst systems. Regarding quantitative measurement of karst system geometry, at scales to 0.1 m, X-ray computed tomography enables good detection of detailed (sub-millimeter) pore space in karstic rocks. Three-dimensional printing allows reconstruction of fragile high porosity rocks, and surrogate samples generated this way can then be subjected to laboratory testing. Borehole scales can be accessed with high-resolution ( 0.001 m) Digital Optical Borehole Imaging technologies and can provide virtual samples more representative of the true nature of karst aquifers than can obtained from coring. Subsequent extrapolation of such samples can generate three-dimensional models suitable for direct modeling of flow and transport. Finally, new cave mapping techniques are beginning to provide information than can be applied to direct simulation of flow. Due to flow rates and cave

    In the last few years there has been significant development of radiation therapy (RT) equipment with advanced imaging and delivery techniques, as well as treatment planning systems. From this perspective, proactive approaches for risk assessment were identified as a powerful tool in modern radiation oncology. A multidisciplinary working group (WG) has been established in the framework of the Italian association for medical physics (AIFM) to promote the use of prospective approaches in the radiotherapy scientific community. This paper describes the main actions carried out by the WG in order to collect information about the engagement of Italian medical physicists in the risk management process, in reporting possible incidents in RT and in the procedures of collecting and analysing near misses. In particular, the main scope of the study was to evaluate the actual level of experience in use of proactive risk analysis tools in modern RT by medical physicists. Finally, the measures implemented by the WG in order to promote the use of such approaches, and consequently to contribute to enhancing safety and radiation protection culture in radiation oncology are described.

    The quality by design (QbD) approach was applied for optimizing the formulation of extemporaneously prepared orodispersible films (ODFs) using Design-Expert® Software. The starting formulation was based on earlier experiments and contained the film forming agents hypromellose and carbomer 974P and the plasticizer glycerol (Visser et al., 2015). Trometamol and disodium EDTA were added to stabilize the solution. To optimize this formulation a quality target product profile was established in which critical quality attributes (CQAs) such as mechanical properties and disintegration time were defined and quantified. As critical process parameters (CPP) that were evaluated for their effect on the CQAs the percentage of hypromellose and the percentage of glycerol as well as the drying time were chosen. Response surface methodology (RMS) was used to evaluate the effects of the CPPs on the CQAs of the final product. The main factor affecting tensile strength and Young's modulus was the percentage of glycerol. Elongation at break was mainly influenced by the drying temperature. Disintegration time was found to be sensitive to the percentage of hypromellose. From the results a design space could be created. As long as the formulation and process variables remain within this design space, a product is obtained with desired characteristics and that meets all set quality requirements.

    To minimize the mortality rates of individuals affected by disasters, providing high-quality food relief during the initial stages of an emergency is crucial. The goal of this study was to develop a formulation for a high-energy, nutrient-dense prototype using linear programming (LP) model as a novel method for developing formulations for food products. The model consisted of the objective function and the decision variables, which were the formulation costs and weights of the selected commodities, respectively. The LP constraints were the Institute of Medicine and the World Health Organization specifications of the content of nutrients in the product. Other constraints related to the product's sensory properties were also introduced to the model. Nonlinear constraints for energy ratios of nutrients were linearized to allow their use in the LP. Three focus group studies were conducted to evaluate the palatability and other aspects of the optimized formulation. New constraints were introduced to the LP model based on the focus group evaluations to improve the formulation. LP is an appropriate tool for designing formulations of food products to meet a set of nutritional requirements. This method is an excellent alternative to the traditional 'trial and error' method in designing formulations. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    lower bound on one data instance in the benchmark data set from the second international timetabling competition. Regarding upper bounds, the formulation based on the minimum cost flow problem performs better on average than other mixed integer programming approaches for the CTT.......In this paper we present two mixed-integer programming formulations for the Curriculum based Course Timetabling Problem (CTT). We show that the formulations contain underlying network structures by dividing the CTT into two separate models and then connect the two models using flow formulation...... techniques. The first mixed-integer programming formulation is based on an underlying minimum cost flow problem, which decreases the number of integer variables significantly and improves the performance compared to an intuitive mixed-integer programming formulation. The second formulation is based...

    Full Text Available Modern society, which sets problems of translating culture in a new way, determines new criteria for the educational paradigm. Globalization tendencies in modern educational environment induce the problem of necessity to integrate educational and scientific resources into Russian education. The aim of this article is to demonstrate a significant part of scientific research as a consistent factor in formation of the competence-based model of a professional. It is shown that students’ research work beyond the process of education becomes a unique sort of teaching activity, which has a number of essential differences from the main traditional teaching techniques for compulsory courses. The results of students’ research work in the ecological situation of Siberian region are presented. The competencies acquired by students during this work are revealed. It is noticed that integrating the theme of students’ research work with compulsory courses is one of the most important teaching peculiarities in formation of personal attributes of a future highly-qualified professional, which form the basis of professional mobility and competitiveness. It is summarized that an interdisciplinary character of research work in the modern educational paradigm is aimed at solving innovative tasks of integrating educational, scientific and practice-oriented constituents in the context of the competency building approach.

    2012-01-05

    A simple systematic approach using Fourier transform infrared (FTIR) spectroscopy, size exclusion chromatography (SEC) and design of experiments (DOE) techniques was applied to the analysis of aggregation factors for protein formulations in stress and accelerated testings. FTIR and SEC were used to evaluate protein conformational and storage stabilities, respectively. DOE was used to determine the suitable formulation and to analyze both the main effect of single factors and the interaction effect of combined factors on aggregation. Our results indicated that (i) analysis at a low protein concentration is not always applicable to high concentration formulations; (ii) an investigation of interaction effects of combined factors as well as main effects of single factors is effective for improving conformational stability of proteins; (iii) with the exception of pH, the results of stress testing with regard to aggregation factors would be available for suitable formulation instead of performing time-consuming accelerated testing; (iv) a suitable pH condition should not be determined in stress testing but in accelerated testing, because of inconsistent effects of pH on conformational and storage stabilities. In summary, we propose a three-step strategy, using FTIR, SEC and DOE techniques, to effectively analyze the aggregation factors and perform a rapid screening for suitable conditions of protein formulation.

    Ksenia Kolkunova

    2014-12-01

    Full Text Available This paper provides an analysis of contemporary Russian academic literature on spirituality. The authors single out key features of these texts, especially their approach to defi ning their subject. They formulate major semantic contexts within which spirituality is discussed by sociologists and psychologists, as well as practical implications of the term. The authors compare the academic usage of the term ‘spirituality’ with its usage in everyday language; the comparison is based on a mass survey conducted in 2006. In the literature that served as the material for the present study, we can observe political, cultural and religious aspects of spirituality. It can be viewed as a form of patriotism, as religious worldview, as overcoming the limitations of human nature, as erudition, as a means to fi ght the non-spiritual character of modern society, or as an aspiration towards the ideal. The overall fuzziness of the term is a consequence of its emotional and utopian connotations in the Russian language.

    We applied the Quality by Design (QbD) approach to the development of poly(lactic-co-glycolic acid) (PLGA) nanoparticle formulations encapsulating triamcinolone acetonide, and the critical process parameters (CPPs) were identified to clarify the correlations between critical quality attributes and CPPs. Quality risk management was performed by using an Ishikawa diagram and experiments with a fractional factorial design (ANOVA). The CPPs for particle size were PLGA concentration and rotation speed, and the CPP for relative drug loading efficiency was the poor solvent to good solvent volume ratio. By assessing the mutually related factors in the form of ratios, many factors could be efficiently considered in the risk assessment. We found a two-factor interaction between rotation speed and rate of addition of good solvent by using a fractional factorial design with resolution V. The system was then extended by using a central composite design, and the results obtained were visualized by using the response surface method to construct a design space. Our research represents a case study of the application of the QbD approach to pharmaceutical development, including formulation screening, by taking actual production factors into consideration. Our findings support the feasibility of using a similar approach to nanoparticle formulations under development. We could establish an efficient method of analyzing the CPPs of PLGA nanoparticles by using a QbD approach.

Natural science is the science about nature as a single unity or totality of the natural sciences, which constituting a single unit. The main aim of the course is to develop student’s natural science competence through integrated mastering system knowledge about nature and man, the basics of environmental knowledge, ways of improving teaching and learning activities, development of value orientations in relation to the nature. There is strong need to review approaches to teaching nature science at schools, taking into account the general trend of greening of the educational process. The aim of the work is to analyze the possibility of practical application of modern approaches to differentiated teaching of the nature science at school greening within the educational process. In our view, the environmental component may be a basis to the formation and differentiated teaching in general. The environmental component of the educational sector has been aimed to the student’s environmental consciousness and compliance with rules of environmentally safe behavior in the environment. The learning of the integrated knowledge about nature and man can be submitted through the prism of action of the environmental factors according classic approach to their classification: abiotic, biotic and anthropogenic factors. In parallel, it is reasonable to raise the issues of practical importance as some natural objects and actions of each of these factors. The new degree of the studying of the environment has been provided by the beginning of the systematization of knowledge about natural objects and structure of the universe, by the formation of primary concepts about the relationship between the world of the living and inanimate nature, between organisms and between human activities and changes that has been occurred in the

    Full Text Available The 21st century is the era of the development of corporate social responsibility (CSR. It is encouraged by the development of the company as a business and societal entities that balances public and private interests. If there is a balance of public and private interests in the company, the application of CSR should be able to accommodate the public interest. But many companies in Indonesia do not involve the community in the formulation of CSR implementation model. This resulted in the implementation of CSR is often not well targeted. In that context, the theory of corporate constitutionalism becomes relevant theory to answer these problems. The theory of corporate constitutionalism put deliberation as one of the principles to achieve the legitimacy of decision-making in the corporation. Through a process of deliberation formulation of CSR model with the community, not just the interests of shareholders that can be accommodated but also the interests of stakeholders. Thus, CSR can actually be instrumental in the global and local challenges.

  13. Modernized Approach for Generating Reproducible Heterogeneity Using Transmitted-Light for Flow Visualization Experiments

    Jones, A. A.; Holt, R. M.

    2017-12-01

    Image capturing in flow experiments has been used for fluid mechanics research since the early 1970s. Interactions of fluid flow between the vadose zone and permanent water table are of great interest because this zone is responsible for all recharge waters, pollutant transport and irrigation efficiency for agriculture. Griffith, et al. (2011) developed an approach where constructed reproducible "geologically realistic" sand configurations are deposited in sandfilled experimental chambers for light-transmitted flow visualization experiments. This method creates reproducible, reverse graded, layered (stratified) thin-slab sand chambers for point source experiments visualizing multiphase flow through porous media. Reverse-graded stratification of sand chambers mimic many naturally occurring sedimentary deposits. Sandfilled chambers use light as nonintrusive tools for measuring water saturation in two-dimensions (2-D). Homogeneous and heterogeneous sand configurations can be produced to visualize the complex physics of the unsaturated zone. The experimental procedure developed by Griffith, et al. (2011) was designed using now outdated and obsolete equipment. We have modernized this approach with new Parker Deadel linear actuator and programed projects/code for multiple configurations. We have also updated the Roper CCD software and image processing software with the latest in industry standards. Modernization of transmitted-light source, robotic equipment, redesigned experimental chambers, and newly developed analytical procedures have greatly reduced time and cost per experiment. We have verified the ability of the new equipment to generate reproducible heterogeneous sand-filled chambers and demonstrated the functionality of the new equipment and procedures by reproducing several gravity-driven fingering experiments conducted by Griffith (2008).

  16. Post-communism: postmodernity or modernity revisited?

    Science.gov (United States)

    Ray, L

    1997-12-01

    Coinciding with the popularity of postmodern theory, the fall of communism appeared to offer further evidence of the exhaustion of modernity. Such analysis is grounded in a view that the Soviet system was the epitome of modernity. An alternative approach regards post-communism as opening new terrains of struggle for modernity. Thus Habermas and others suggest that post-communist societies are rejoining the trajectory of western modernity whose problems they now recapitulate. This alternative view implies that Soviet systems were something other than 'modern', although their nature is not always clearly defined. However, even if post-communist societies do encounter problems of modernity, they do so in new circumstances where modernist notions of social development have become problematic. This article argues that, contrary to those who regard modernization or postmodernization as irresistible trends, core post-communist societies are likely to develop along an alternative path to that of western modernity. This is tentatively described as 'neo-mercantilist'.

    Full Text Available Abstract Background The objective of this study is to identify the critical formulation parameters controlling distribution and function for the rectal administration of microbicides in humans. Four placebo formulations were designed with a wide range of hydrophilic characteristics (aqueous to lipid and rheological properties (Newtonian, shear thinning, thermal sensitive and thixotropic. Aqueous formulations using typical polymers to control viscosity were iso-osmotic and buffered to pH 7. Lipid formulations were developed from lipid solvent/lipid gelling agent binary mixtures. Testing included pharmaceutical function and stability as well as in vitro and in vivo toxicity. Results The aqueous fluid placebo, based on poloxamer, was fluid at room temperature, thickened and became shear thinning at 37°C. The aqueous gel placebo used carbopol as the gelling agent, was shear thinning at room temperature and showed a typical decrease in viscosity with an increase in temperature. The lipid fluid placebo, myristyl myristate in isopropyl myristate, was relatively thin and temperature independent. The lipid gel placebo, glyceryl stearate and PEG-75 stearate in caprylic/capric triglycerides, was also shear thinning at both room temperature and 37°C but with significant time dependency or thixotropy. All formulations showed no rectal irritation in rabbits and were non-toxic using an ex vivo rectal explant model. Conclusions Four placebo formulations ranging from fluid to gel in aqueous and lipid formats with a range of rheological properties were developed, tested, scaled-up, manufactured under cGMP conditions and enrolled in a formal stability program. Clinical testing of these formulations as placebos will serve as the basis for further microbicide formulation development with drug-containing products.

    Carrera, Erasmo; Petrolo, Marco; Zappino, Enrico

    2014-01-01

    The finite element method (FEM) is a computational tool widely used to design and analyse  complex structures. Currently, there are a number of different approaches to analysis using the FEM that vary according to the type of structure being analysed: beams and plates may use 1D or 2D approaches, shells and solids 2D or 3D approaches, and methods that work for one structure are typically not optimized to work for another. Finite Element Analysis of Structures Through Unified Formulation deals with the FEM used for the analysis of the mechanics of structures in the case of linear elasticity. The novelty of this book is that the finite elements (FEs) are formulated on the basis of a class of theories of structures known as the Carrera Unified Formulation (CUF). It formulates 1D, 2D and 3D FEs on the basis of the same ''fundamental nucleus'' that comes from geometrical relations and Hooke''s law, and presents both 1D and 2D refined FEs that only have displacement variables as in 3D elements. It also covers 1D...

    Banta, J E

    1987-01-01

    William Petty, physician, epidemiologist, political economist, demographer, cartographer, and administrator was an intellectual product of the seventeenth century. Petty was born in the year 1623 in Romsey, England of lower middle class parents; however, by the time of his death in 1687 he had become a knight of the realm, founder of the Royal Society, and friend of kings. Petty's life reflected the northern renaissance which induced such dramatic changes in science, technology, politics, and entrepreneurship. His education was eclectic, nonetheless he took his Doctor of Physic degree from Oxford in 1649 and became an Oxford don, where he spent the next few years as an academic before undertaking a definitive survey of Ireland on behalf of the Cromwell government. Ireland changed Petty's destiny and he became a man of the world and entrepreneur which stimulated his interest in public policy formulation and economics. It was Petty's peculiar genius to be innovative in the application of measurement, statistics, and mathematics to socioeconomic and demographic phenomena. As a physician he related his knowledge of health and disease to these phenomena in what in the modern context would be called human ecology or social epidemiology. These relationships and their measurement were employed to establish an objective set of data which could be analyzed for the purpose of rational public policy planning by the state. This scientific approach to public policy places Petty squarely in the context of modern epidemiologic and public health practice and marks the initiation of a major use of the epidemiologic method.

    In this paper, the accuracies of the geometrically exact beam and absolute nodal coordinate formulations are studied by comparing their predictions against an experimental data set referred to as the “Princeton beam experiment.” The experiment deals with a cantilevered beam experiencing coupled flap, lag, and twist deformations. In the absolute nodal coordinate formulation, two different beam elements are used. The first is based on a shear deformable approach in which the element kinematics is described using two nodes. The second is based on a recently proposed approach featuring three nodes. The numerical results for the geometrically exact beam formulation and the recently proposed three-node absolute nodal coordinate formulation agree well with the experimental data. The two-node beam element predictions are similar to those of linear beam theory. This study suggests that a careful and thorough evaluation of beam elements must be carried out to assess their ability to deal with the three-dimensional deformations typically found in flexible multibody systems.

  6. Pricing index-based catastrophe bonds: Part 1: Formulation and discretization issues using a numerical PDE approach

    Science.gov (United States)

    Unger, André J. A.

    2010-02-01

    This work is the first installment in a two-part series, and focuses on the development of a numerical PDE approach to price components of a Bermudan-style callable catastrophe (CAT) bond. The bond is based on two underlying stochastic variables; the PCS index which posts quarterly estimates of industry-wide hurricane losses as well as a single-factor CIR interest rate model for the three-month LIBOR. The aggregate PCS index is analogous to losses claimed under traditional reinsurance in that it is used to specify a reinsurance layer. The proposed CAT bond model contains a Bermudan-style call feature designed to allow the reinsurer to minimize their interest rate risk exposure on making substantial fixed coupon payments using capital from the reinsurance premium. Numerical PDE methods are the fundamental strategy for pricing early-exercise constraints, such as the Bermudan-style call feature, into contingent claim models. Therefore, the objective and unique contribution of this first installment in the two-part series is to develop a formulation and discretization strategy for the proposed CAT bond model utilizing a numerical PDE approach. Object-oriented code design is fundamental to the numerical methods used to aggregate the PCS index, and implement the call feature. Therefore, object-oriented design issues that relate specifically to the development of a numerical PDE approach for the component of the proposed CAT bond model that depends on the PCS index and LIBOR are described here. Formulation, numerical methods and code design issues that relate to aggregating the PCS index and introducing the call option are the subject of the companion paper.

    Full Text Available Nowadays it is essential to modernize credit relations in the conditions of global economy transformations. This is due to the influence of integration processes on credit relations and transformation of the risks inherent in the credit field. The purpose of this article is to develop measures that help to improve the efficiency of interaction of credit relations’ participants. Modernization of credit relations is based on the interaction of its main and indirect subjects who belong to the subsystems of loans granting, deposits attraction and provision of related services. Its goal is to pass from extensive to intensive model of interaction between the subjects of credit relations. Components of the credit relations modernization are the following: institutional modernization, which is based on the interaction of credit relations’ subjects, and ensures the development of competition in all credit market’s segments, the creation of its corresponding infrastructure, qualitative change in the approaches of regulation and supervision; technological modernization, which involves the formation of joint products on the credit market and the formation of an integrated informational and analytical system. In the result of the credit relations’ modernization it is expected to achieve synergies between the subjects of credit relations, that will lead to changes in the business architecture of the financial market.

    Understanding the relevant biological activity of any pharmaceutical formulation destined for human use is crucial. For vaccine-based formulations, activity must reflect the expected immune response, while for non-vaccine therapeutic agents, such as monoclonal antibodies, a lack of immune response to the formulation is desired. During early formulation development, various biochemical and biophysical characteristics can be monitored in a high-throughput screening (HTS) format. However, it remains impractical and arguably unethical to screen samples in this way for immunological functionality in animal models. Furthermore, data for immunological functionality lag formulation design by months, making it cumbersome to relate back to formulations in real-time. It is also likely that animal testing may not accurately reflect the response in humans. For a more effective formulation screen, a human whole blood (hWB) approach can be used to assess immunological functionality. The functional activity relates directly to the human immune response to a complete formulation (adjuvant/antigen) and includes adjuvant response, antigen response, adjuvant-modulated antigen response, stability, and potentially safety. The following commentary discusses the hWB approach as a valuable new tool to de-risk manufacture, formulation design, and clinical progression.

    Full Text Available The purpose of present study was to optimize rizatriptan (RZT chitosan (CS nanoparticles using ionic gelation method by application of quality by design (QbD approach. Based on risk assessment, effect of three variables, that is CS %, tripolyphosphate % and stirring speed were studied on critical quality attributes (CQAs; particle size and entrapment efficiency. Central composite design (CCD was implemented for design of experimentation with 20 runs. RZT CS nanoparticles were characterized for particle size, polydispersity index, entrapment efficiency, in-vitro release study, differential scanning calorimetric, X-ray diffraction, scanning electron microscopy (SEM. Based on QbD approach, design space (DS was optimized with a combination of selected variables with entrapment efficiency > 50% w/w and a particle size between 400 and 600 nm. Validation of model was performed with 3 representative formulations from DS for which standard error of − 0.70-3.29 was observed between experimental and predicted values. In-vitro drug release followed initial burst release 20.26 ± 2.34% in 3-4 h with sustained drug release of 98.43 ± 2.45% in 60 h. Lower magnitude of standard error for CQAs confirms the validation of selected CCD model for optimization of RZT CS nanoparticles. In-vitro drug release followed dual mechanism via, diffusion and polymer erosion. RZT CS nanoparticles were prepared successfully using QbD approach with the understanding of the high risk process and formulation parameters involved and optimized DS with a multifactorial combination of critical parameters to obtain predetermined RZT loaded CS nanoparticle specifications.

    Microemulsion formulations represent an interesting delivery vehicle for lipophilic drugs, allowing for improving their solubility and dissolution properties. This work developed effective microemulsion formulations using glyburide (a very poorly-water-soluble hypoglycaemic agent) as a model drug. First, the area of stable microemulsion (ME) formations was identified using a new approach based on mixture experiment methods. A 13-run mixture design was carried out in an experimental region defined by constraints on three components: aqueous, oil and surfactant/cosurfactant. The transmittance percentage (at 550 nm) of ME formulations (indicative of their transparency and thus of their stability) was chosen as the response variable. The results obtained using the mixture experiment approach corresponded well with those obtained using the traditional approach based on pseudo-ternary phase diagrams. However, the mixture experiment approach required far less experimental effort than the traditional approach. A subsequent 13-run mixture experiment, in the region of stable MEs, was then performed to identify the optimal formulation (i.e., having the best glyburide dissolution properties). Percent drug dissolved and dissolution efficiency were selected as the responses to be maximized. The ME formulation optimized via the mixture experiment approach consisted of 78% surfactant/cosurfacant (a mixture of Tween 20 and Transcutol, 1:1, v/v), 5% oil (Labrafac Hydro) and 17% aqueous phase (water). The stable region of MEs was identified using mixture experiment methods for the first time. Copyright © 2011 Elsevier B.V. All rights reserved.

    The Dtxd (Diphtheria toxoid) was the first antigen encapsulated within liposomes, their adjuvant properties were discovered (their capacity to enhance the vaccine immunogenicity). The point here is not to propose a new method to prepare this lipossomal vaccine. The central idea is to give new dresses for old vaccines by using classical and well-established liposome preparation method changing only the encapsulation pH and the immunization protocol. The most appropriate method of Dtxd encapsulation within liposome was based on lipid film hydration in 100 mM citrate buffer, pH 4.0. This was accompanied by changes on protein hydrophobicity, observed by CD and fluorescence spectroscopies. Whenever the Dtxd exposed its hydrophobic residues at pH 4.0, it interacted better with the lipossomal (observed by electrophoretic mobility) film than when its hydrophobic residues were buried (pH 9.0). The Dtxd partition coefficient in Triton-X114 and the acrylamide fluorescence quenching were also pH dependent. Both were bigger at pH 4.0 than at pH 9.0. The relationship protein structure and lipid interaction was pH dependent and now it can be easily maximized to enhance encapsulation of antigens in vaccine development. Mice were primed with formulations containing 5 mug of Dtxd within liposomes prepared in pH 4.0 or 7.0 or 9.0. The boosters were done 38 or 138 days after the first immunization. The IgM produced by immediate response of all lipossomal formulations were higher than the control (free protein). The response patterns and the immune maturity were measured by IgG1 and IgG2a titrations. The IgG1 titers produced by both formulations at pH 4.0 and 7.0 were at least 22 higher than those produced by mice injected lipossomal formulation at pH 9.0. When the boosters were done, 138 days after priming the mice produced a IgG2a titer of 29 and the group that received the booster 30 days after priming produced a titer of 25. The strongest antibody production was the neutralizing

    The objective of the present study was to utilize dual asymmetric centrifugation (DAC) as a novel processing approach for the production of liposomes-in-hydrogel formulations. Lipid films of phosphatidylcholine, with and without chloramphenicol (CAM), were hydrated and homogenized by DAC to produce liposomes in the form of vesicular phospholipid gels with a diameter in the size range of 200-300 nm suitable for drug delivery to the skin. Different homogenization processing parameters were investigated along with the effect of adding propylene glycol (PG) to the formulations prior to homogenization. The produced liposomes were incorporated into a hydrogel made of 2.5% (v/v) soluble β-1,3/1,6-glucan (SBG) and mixed by DAC to achieve a homogenous liposomes-in-hydrogel-formulation suitable for topical application. CAM-containing liposomes with a vesicle diameter of 282 ± 30 nm and polydispersity index (PI) of 0.13 ± 0.02 were successfully produced by DAC after 50 min centrifugation at 3500 rpm, and homogenously (< 4% content variation) incorporated into the SBG hydrogel. Addition of PG decreased the necessary centrifugation time to 2 min and 55 s, producing liposomes of 230 ± 51 nm and PI of 0.25 ± 0.04. All formulations had an entrapment efficiency of approximately 50%. We managed to develop a relatively fast and reproducible new method for the production of liposomes-in-hydrogel formulations by DAC.

    Satoh, Ichiro

    A formal approach for specifying and reasoning about earth-friendly logistics management systems is presented. To reduce fossil fuel consumption and carbon dioxide emissions resulting from transport, we must enhance the transport efficiency of trucks, which play an essential role as carriers in modern logistics services. This paper addresses the milk-run approach. It is one of the most effective and popular solutions to this problem, but it makes it be complicated to implement in a logistics management system. We propose a language for specifying the routes of trucks and an order relation between the requirements of routes and the possible routes of trucks. The former is formulated as process calculus and the latter selects suitable trucks according to their routes.

    Vitamin E tocopherol polyethylene glycol succinate (TPGS) is a non-ionic surface active agent, known to enhance the bioavailability of lipophilic compounds via wettability, solubility, and in some cases permeability enhancement. MK-0536 is an anti-retroviral drug with poor wettability and solubility and a high dose. Based on pharmacokinetic studies in dogs and humans, use of vitamin E TPGS in oral solid formulations of MK-0536 provides desired PK characteristics. The use of vitamin E TPGS, however, in solid dosage forms is limited because of the processing challenges resulting from its waxy nature and low melting temperature (∼37°C). The current study, for the first time, demonstrates the use of an alternative low pressure extrusion and spheronization approach to enable high loadings of the poorly soluble, poorly compactable drug and relatively high levels of vitamin E TPGS. This approach not only aided in mitigating processing challenges arising from most high energy process steps such as milling, compression, and coating, but also enabled a higher drug load formulation that provided superior bioperformance relative to a conventional high shear wet granulated formulation. An encapsulated dosage form consisting of pellets prepared by extrusion spheronization with 75% (w/w) MK-0536 and 10% (w/w) vitamin E TPGS was developed. © 2015 Wiley Periodicals, Inc. and the American Pharmacists Association.

    2013-01-01

    A systematic approach is presented for developing entropy stable (SS) formulations of any order for the Navier-Stokes equations. These SS formulations discretely conserve mass, momentum, energy and satisfy a mathematical entropy inequality. They are valid for smooth as well as discontinuous flows provided sufficient dissipation is added at shocks and discontinuities. Entropy stable formulations exist for all diagonal norm, summation-by-parts (SBP) operators, including all centered finite-difference operators, Legendre collocation finite-element operators, and certain finite-volume operators. Examples are presented using various entropy stable formulations that demonstrate the current state-of-the-art of these schemes.

    Posttraumatic stress disorder (PTSD) is a common psychiatric illness, increasingly in the public spotlight in the United States due its prevalence in the soldiers returning from combat in Iraq and Afghanistan. This educational review presents a contemporary approach for how to incorporate a modern neuroscience perspective into an integrative case formulation. The article is organized around key neuroscience "themes" most relevant for PTSD. Within each theme, the article highlights how seemingly diverse biological, psychological, and social perspectives all intersect with our current understanding of neuroscience. Any contemporary neuroscience formulation of PTSD should include an understanding of fear conditioning, dysregulated circuits, memory reconsolidation, epigenetics, and genetic factors. Fear conditioning and other elements of basic learning theory offer a framework for understanding how traumatic events can lead to a range of behaviors associated with PTSD. A circuit dysregulation framework focuses more broadly on aberrant network connectivity, including between the prefrontal cortex and limbic structures. In the process of memory reconsolidation, it is now clear that every time a memory is reactivated it becomes momentarily labile-with implications for the genesis, maintenance, and treatment of PTSD. Epigenetic changes secondary to various experiences, especially early in life, can have long-term effects, including on the regulation of the hypothalamic-pituitary-adrenal axis, thereby affecting an individual's ability to regulate the stress response. Genetic factors are surprisingly relevant: PTSD has been shown to be highly heritable despite being definitionally linked to specific experiences. The relevance of each of these themes to current clinical practice and its potential to transform future care are discussed.

    Fleming, P.

    1985-01-01

    A design technique is proposed for linear regulators in which a feedback controller of fixed structure is chosen to minimize an integral quadratic objective function subject to the satisfaction of integral quadratic constraint functions. Application of a non-linear programming algorithm to this mathematically tractable formulation results in an efficient and useful computer-aided design tool. Particular attention is paid to computational efficiency and various recommendations are made. Two design examples illustrate the flexibility of the approach and highlight the special insight afforded to the designer.

    2017-08-01

    Development of palatable formulations for pediatric and geriatric patients involves various challenges. However, an innovative development with beneficial characteristics of marketed formulations in a single formulation platform was attempted. The goal of this research was to develop solid oral flexible tablets (OFTs) as a platform for pediatrics and geriatrics as oral delivery is the most convenient and widely used mode of drug administration. For this purpose, a flexible tablet formulation using cetirizine hydrochloride as model stability labile class 1 and 3 drug as per the Biopharmaceutical Classification System was developed. Betadex, Eudragit E100, and polacrilex resin were evaluated as taste masking agents. Development work focused on excipient selection, formulation processing, characterization methods, stability, and palatability testing. Formulation with a cetirizine-to-polacrilex ratio of 1:2 to 1:3 showed robust physical strength with friability of 0.1% (w/w), rapid in vitro dispersion within 30 s in 2-6 ml of water, and 0.2% of total organic and elemental impurities. Polacrilex resin formulation shows immediate drug release within 30 min in gastric media, better taste masking, and acceptable stability. Hence, it is concluded that ion exchange resins can be appropriately used to develop taste-masked, rapidly dispersible, and stable tablet formulations with tailored drug release suitable for pediatrics and geriatrics. Flexible formulations can be consumed as swallowable, orally disintegrating, chewable, and as dispersible tablets. Flexibility in dose administration would improve compliance in pediatrics and geriatrics. This drug development approach using ion exchange resins can be a platform for formulating solid oral flexible drug products with low to medium doses.

    The present investigation was carried out to understand the impact of formulation and process variables on the quality of oral disintegrating films (ODF) using Quality by Design (QbD) approach. Lamotrigine (LMT) was used as a model drug. Formulation variable was plasticizer to film former ratio and process variables were drying temperature, air flow rate in the drying chamber, drying time and wet coat thickness of the film. A Definitive Screening Design of Experiments (DoE) was used to identify and classify the critical formulation and process variables impacting critical quality attributes (CQA). A total of 14 laboratory-scale DoE formulations were prepared and evaluated for mechanical properties (%elongation at break, yield stress, Young's modulus, folding endurance) and other CQA (dry thickness, disintegration time, dissolution rate, moisture content, moisture uptake, drug assay and drug content uniformity). The main factors affecting mechanical properties were plasticizer to film former ratio and drying temperature. Dissolution rate was found to be sensitive to air flow rate during drying and plasticizer to film former ratio. Data were analyzed for elucidating interactions between different variables, rank ordering the critical materials attributes (CMA) and critical process parameters (CPP), and for providing a predictive model for the process. Results suggested that plasticizer to film former ratio and process controls on drying are critical to manufacture LMT ODF with the desired CQA. Published by Elsevier B.V.

    As the need to model flexibility arose in multibody dynamics, the floating frame of reference formulation was developed, but this approach can yield inaccurate results when elastic displacements becomes large. While the use of three-dimensional finite element formulations overcomes this problem, the associated computational cost is overwhelming. Consequently, beam models, which are one-dimensional approximations of three-dimensional elasticity, have become the workhorse of many flexible multibody dynamics codes. Numerous beam formulations have been proposed, such as the geometrically exact beam formulation or the absolute nodal coordinate formulation, to name just two. New solution strategies have been investigated as well, including the intrinsic beam formulation or the DAE approach. This paper provides a systematic comparison of these various approaches, which will be assessed by comparing their predictions for four benchmark problems. The first problem is the Princeton beam experiment, a study of the static large displacement and rotation behavior of a simple cantilevered beam under a gravity tip load. The second problem, the four-bar mechanism, focuses on a flexible mechanism involving beams and revolute joints. The third problem investigates the behavior of a beam bent in its plane of greatest flexural rigidity, resulting in lateral buckling when a critical value of the transverse load is reached. The last problem investigates the dynamic stability of a rotating shaft. The predictions of eight independent codes are compared for these four benchmark problems and are found to be in close agreement with each other and with experimental measurements, when available.

  3. Requirements of modernization strategies

    Instrumentation and control contributed a major share to the current level of safety, economic efficiency, and availability of the German nuclear power plants. German NPPs occupy a top position in this respect at international level, but novel instrumentation and digital control technology alone will not guarantee further enhancements. Therefore, the owner/operators established carefully devised maintenance and modernization strategies in order to safeguard their NPPs top position in the long run. The German NPPs are the most thoroughly automated plants of the world. In addition to the sweeping modernization strategies recommended by the plant manufacturers, based on computer-supported control, alternative modernization strategies have been considered in the evaluation process. This approach provides for room for maneuvre, for manufacturers as well as managers responsible for risk and cost optimization, which is a major task in view of the changing regulatory framework in the electricity market.

  6. Gellnerovo pojetí modernity

    Jiří Musil

    2017-10-01

    Full Text Available Gellner’s theory of modernity is a complex structure, it matured several decades and during this process he modified some of its elements. The following interpretation of his theory is based on the analysis of three pillars of his thought, first on his epistemological axioms, second on his concept of philosophy of human history and third on his conception of social theory. Gellner’s theory of knowledge is a cluster composed of classical empiricism, kantian rationalism, enriched by weberian understanding of historical modifications of rationalism in modern times. Gellner adds to these two pillars his concept of cultural perspectivism and his interpretation of evolutionism, so called truncated evolutionism that concentrates on the emergence of modernity. Gellner’s philosophy of history is based on his analysis of interaction between three basic functional entities of all human societies: economy, power, knowledge. Gellner rather carefully analyzed as well the relationship between the role of material and ideational factors in human history, and between sociological analyses based on causal. In his view sociology has to use both approaches. Gellner is stressing the fact that to the most important elements of modernity belongs science, but at the same time he is fully aware of the fact that science can not tell us “what to do”. Here he follows Max Weber’s thesis on the disenchantment as an element of modernity.

    2017-03-01

    Continuous improvements in techniques, instruments, and materials have established modern endodontic microsurgery as a state-of-the-art treatment method. The purpose of this approach was to introduce a new surgical endodontic technique by using a three-dimensional printed template for guided osteotomy and root resection. A 38-year-old patient was diagnosed with periapical lesions of teeth #3 and #4 and extruded gutta-percha material. Three-dimensional radiographic and optical scan files were imported into surgical planning software designed for guided implant surgery. Within the adapted software program the periapical lesions and the extruded gutta-percha were visualized and marked. With the aid of virtually positioned surgical pins and piezoelectric instruments, the osteotomy size, the apical resection level, and the bevel angle were defined before treatment. Three-dimensional surgical templates for each tooth were designed within the software program for a guided treatment approach. This approach comprised the treatment of periapical lesions of teeth #3 and #4 with root-end fillings and the detection and complete removal of the extruded gutta-percha material without perforation of sinus membrane. There were no postoperative complications, and clinical and radiologic assessments verified complete healing of the teeth. The guided microsurgical endodontic treatment presented appears to be a viable technique that allows for predefined osteotomies and root resections.

The Helmholtz equation is obtained as a special case of the mixed formulation...... for the elastic shear modulus equating to zero. Hence, by spatial variation of the mass density, shear and bulk moduli we are able to solve the coupled problem by the mixed formulation.

    2005-01-01

    Analogue matching is a palaeolimnological technique that aims to find matches for fossil sediment samples from a set of modern surface sediment samples. Modern analogues were identified that closely matched the pre-disturbance conditions of eight of the UK Acid Waters Monitoring Network (AWMN) lakes using diatom- and cladoceran-based analogue matching. These analogue sites were assessed in terms of hydrochemistry, aquatic macrophytes and macro-invertebrates as to their suitability for defining wider hydrochemical and biological reference conditions for acidified sites within the AWMN. The analogues identified for individual AWMN sites show a close degree of similarity in terms of their hydrochemical characteristics, aquatic macrophytes and, to a lesser extent, macro-invertebrate fauna. The reference conditions of acidified AWMN sites are inferred to be less acidic than today and to support a wider range of acid-sensitive aquatic macrophyte and macro-invertebrate taxa than that recorded in the AWMN lakes over the period of monitoring since 1988. - The use of a palaeolimnological technique to identify modern ecological reference analogues for acidified lakes is demonstrated

    When entering into a design program that is a marriage between two designs it is very difficult to separate self imposed design criteria from the requirements of the program. Therefore, the criteria of and the requirements for the Westinghouse modernization program will be discussed as one. These are outlined below: 1) The OSART Mission that was conducted by the IAEA at the Temelin Plant in 1990 identified the need to provide a new comprehensive Safety Analysis to verify the various aspects of the WWER safety system design. This recommendation is one that Westinghouse will provide as part of the WWER I and C Modernization Program. The design, no matter how well proven or verified from a hardware design point of view, is only as good as the basis for the system design; 2) Minimize the impact on the civil design aspects of the plant where possible and where this requirements do not affect the safety features of the design; 3) Ensure compatibility of the design to meet the latest US NRC requirements and those of the implementing country, applicable to the systems functional and hardware designs. This is a Westinghouse standard corporate requirement for all nuclear plant and systems design whether they be foreign or domestic; 4) Provide the most modern, proven design for the I and C systems. Application of the Westinghouse Instrumentation and Control microprocessor based design to the WWER Modernization Program will provide the basis for upgrading plants to meet western standards.

  18. How does Modernity Taste? Tomatoes in the Societal Change from Modernity to Late Modernity

    Directory of Open Access Journals (Sweden)

    Lena Ekelund

    2011-10-01

    Full Text Available The aim of this article is to discuss how changes in tomato food regulation, production and consumption, can be seen as part of a broader societal change from Modernity to Late Modernity. Based on evidence from the Swedish and European food systems we demonstrate how a system, which has been successfully managing development in food production for several decades by stressing rationality, homogeneity and standardization, is being challenged by a system that has adapted to, and also exploited, consumer preferences such as heterogeneity, diversity and authenticity. The article shows how tomato growers develop differentiation strategies, adapting to and cultivating this new consumer interest, and how authorities responsible for regulations of trade and quality struggle to adapt to the new situation. As the products become more diversified, taste becomes an important issue and is associated with a view that traditional and natural are superior to standardized and homogeneous products. The analytical approaches for the discussion come from two study areas: ethnological, and marketing and policy perspective, thus showing a multidimensional picture of a changing food system.

    Directory of Open Access Journals (Sweden)

    Lynn Hunt

    2014-12-01

    Full Text Available “Modernity” has recently been the subject of considerable discussion among historians. This article reviews some of the debates and argues that modernity is a problematic concept because it implies a complete rupture with “traditional” ways of life. Studies of key terms are undertaken with the aid of Google Ngrams. These show that “modernity,” “modern times,” and “traditional” —in English and other languages— have a history of their own. A brief analysis of the shift from a self oriented toward equilibrium to a self oriented toward stimulation demonstrates that modernity is not necessary to historical analysis.

  20. From ancient to avant-garde: a review of traditional and modern multimodal approaches to surgical anatomy education.

    Science.gov (United States)

    Hu, Minhao; Wattchow, David; de Fontgalland, Dayan

    2018-03-01

    The landscape of surgical anatomy education is progressively changing. Traditional methods, such as cadaveric dissection and didacticism are being increasingly phased out in undergraduate courses for multimodal approaches incorporating problem-based learning, radiology and computer-based simulations. Although effective at clinically contextualizing and integrating anatomical information, these approaches may be a poor substitute for fostering a grasp of foundational 'pure' anatomy. Dissection is ideal for this purpose and hence remains the cornerstone of anatomical education. However, novel methods and technological advancements continually give way to adjuncts such as cadaveric surgery, three-dimensional printing, virtual simulation and live surgical streaming, which have demonstrated significant efficacy alone or alongside dissection. Therefore, although divergent paradigms of 'new versus old' approaches have engulfed and divided the community, educators should seek to integrate the ancient and avant-garde to comprehensively satisfy all of the modern anatomy learner's educational needs. © 2017 Royal Australasian College of Surgeons.

  1. A geometrically exact beam element based on the absolute nodal coordinate formulation

    Gerstmayr, Johannes; Matikainen, Marko K.; Mikkola, Aki M.

    2008-01-01

    In this study, Reissner's classical nonlinear rod formulation, as implemented by Simo and Vu-Quoc by means of the large rotation vector approach, is implemented into the framework of the absolute nodal coordinate formulation. The implementation is accomplished in the planar case accounting for coupled axial, bending, and shear deformation. By employing the virtual work of elastic forces similarly to Simo and Vu-Quoc in the absolute nodal coordinate formulation, the numerical results of the formulation are identical to those of the large rotation vector formulation. It is noteworthy, however, that the material definition in the absolute nodal coordinate formulation can differ from the material definition used in Reissner's beam formulation. Based on an analytical eigenvalue analysis, it turns out that the high frequencies of cross section deformation modes in the absolute nodal coordinate formulation are only slightly higher than frequencies of common shear modes, which are present in the classical large rotation vector formulation of Simo and Vu-Quoc, as well. Thus, previous claims that the absolute nodal coordinate formulation is inefficient or would lead to ill-conditioned finite element matrices, as compared to classical approaches, could be refuted. In the introduced beam element, locking is prevented by means of reduced integration of certain parts of the elastic forces. Several classical large deformation static and dynamic examples as well as an eigenvalue analysis document the equivalence of classical nonlinear rod theories and the absolute nodal coordinate formulation for the case of appropriate material definitions. The results also agree highly with those computed in commercial finite element codes

    Behaviour between two materials in composite beam is assumed partially interact when longitudinal slip at its interfacial surfaces is considered. Commonly analysed by the mesh-based formulation, this study used meshless formulation known as Element Free Galerkin (EFG) method in the beam partial interaction analysis, numerically. As meshless formulation implies that the problem domain is discretised only by nodes, the EFG method is based on Moving Least Square (MLS) approach for shape functions formulation with its weak form is developed using variational method. The essential boundary conditions are enforced by Langrange multipliers. The proposed EFG formulation gives comparable results, after been verified by analytical solution, thus signify its application in partial interaction problems. Based on numerical test results, the Cubic Spline and Quartic Spline weight functions yield better accuracy for the EFG formulation, compares to other proposed weight functions.

    Vasile DEAC

    2010-01-01

    Full Text Available The maintenance activity isn’t a purpose in itself, it’s a necessity of which "the production suffers" and the financial agent “considers too expensive”. It often exists a conflict between the production units and the maintenance department, not only for a short term, but, sometimes, for a long term, imposing a rigorous definition of each person’s responsibilities. Considering the mutations in the industrial equipments’ technical complexity and the accidental failures’ catastrophic consequences from the economic and/or social point of view, it should be assigned a new dimension to the maintenance activity. One of the imperatives imposed to this action is represented by modern means of informing through the maintenance’s operational computerization.

    Full Text Available When we review the history of modern aesthetic surgery, a name that stands out as bright as a beacon and precious as gold is undoubtedly that of Jacques Joseph. A surgeon, par excellence, far ahead of his time, who chose to think out of the box, Joseph, despite all odds set out to give respectability to Aesthetic Surgery without depriving it of any scientific core values. By his words and deeds proved beyond doubt that only the very best in the field of reconstructive surgery, can visualize the hidden perfection in imperfection and formulate a treatment plan and a surgical strategy to achieve that elusive perfection. The rich surgical literature that he has left behind, the wealth of surgical instruments that he had designed and above all a way of thinking that he propagated, that aesthetic surgery is not frivolous but very serious endeavor, and treating the psychology of the patient is as important as treating his disease, undoubtedly makes him the revered ′Father of Modern Aesthetic Surgery′.

    In this study, we present a grid refinement model in the lattice Boltzmann method (LBM) for two-dimensional incompressible fluid flow. That is, the model combines the desirable features of the lattice Boltzmann method and stream function-vorticity formulations. In order to obtain an accurate result, very fine grid (or lattice) is required near the solid boundary. Therefore, the grid refinement model is used in the lattice Boltzmann method for stream function-vorticity formulation. This approach is more efficient in that it can obtain the same accurate solution as that in single-block approach even if few lattices are used for computation. In order to validate the grid refinement approach for the stream function-vorticity formulation, the numerical simulations of lid-driven cavity flows were performed and good results were obtained.

    We provide a new formulation of non-relativistic diffeomorphism invariance. It is generated by localising the usual global Galilean symmetry. The correspondence with the type of diffeomorphism invariant models currently in vogue in the theory of fractional quantum Hall effect has been discussed. Our construction is shown to open up a general approach of model building in theoretical condensed matter physics. Also, this formulation has the capacity of obtaining Newton–Cartan geometry from the gauge procedure.

    Full Text Available the domain of Art critique and becoming a philosophical argument. How can we think of Perspective as symbolic Form? Is Perspective really a symbolic form? Why is Perspective so important? Because at the beginning of the Modern Age, Perspective as spiritual figure grounds many symbolic or even many scientific constructions. We could we say that perspective open the foundation of modern science as such. The “Geometrization” of Vision, beginning with perspective, will be for us the interpretative key in order to understand the Modern Age as a whole.  This understanding will allow us to understand the anthropologic dimension arising from the Modern Age, called „Perspectivism“. Assuming that perspective was neither only an invention of painting nor of geometry nor of philosophy, taken as singular fields of human inquiry, we will try to sketch the genesis of “perspective” from an interdisciplinary point of view. By doing so, we will also try to fix its deep significance for the anthropology of the Modern Age. Living and feeling in a perspectival world is the real invention of the Modern Age, one that overcame the closed Cosmos of the Middle Ages in order to reveal to mankind its own potential. Our interdisciplinary approach will proceed from many points of view (history of art, science, theology, anthropology and converge on the idea of a new kind of human experience. Such an interdisciplinary approach will open new questions about our present time. Are we justified in thinking of our experience today as perspectival? What does it mean today to think from perspectives in the manifold dimensions of our living and to face to the complexity of our times?

    L.G. Ramensky (1884-1953) was an outstanding Soviet geobotanist of the first part of XX century. Considered is his theoretical legacy and its contribution to modern vegetation science. L.G. Ramensky formulated the principle of vegetation continuum based on which the modern paradigm of vegetation science has been put into shape. The scientist made a contribution to the development of such important theoretical conceptions as types of plant strategy, coenosis and coenobiosis (coexistence of species), patterns of interannual variability in plant communities, ecological successions. The unique ecological scales were established by L.G. Ramensky that characterize the distribution of 1400 species over the gradients of soil moistening, richness, and salinization as well as moistening variability, pastoral digression, and alluvial intensity. He came out against mechanistic notions by V.N. Sukachev on a biogeocoenosis structure. The scientist did not offer his own method of plant communities classification but his well-reasoned criticism of dominant classification played a great role in adoption of floristical classification principles (Braun-Blanquet approach) by phytocenology in our country.

    2009-01-01

    Energy policy has to have a long-term perspective. To formulate it one needs to know the contours of energy requirements and options. Different approaches have been followed in literature, each with their own problems. A top down econometric approach provides little guidance on policies, while a bottom up approval requires too much knowledge and too many assumptions. Using top-down econometric approach for aggregate overall benchmarking and a detailed activity analysis model, Integrated Energy System Model, for a few large sectors, provides a unique combination for easing the difficulties of policy formulation. The model is described in this paper. Eleven alternate scenarios are built, designed to map out extreme points of feasible options. Results show that even after employing all domestic energy resource to their full potential, there will be a continued rise of fossil fuel use, continued importance of coal, and continued rise of import dependence. Energy efficiency emerges as a major option with a potential to reduce energy requirement by as much as 17%. Scenario results point towards pushing for development of alternative sources. (author)

    2017-12-01

    Full Text Available This paper investigates the philosophical foundations of modern bioengineering to articulate its ethical framework. Engineering as an ultimate mechanism to transform knowledge into practice is essential for both physical and biological sciences. It reduces data, concepts, and designs to pictorial forms. The integration of engineering with the newly emerging biosciences, has presented a unique opportunity to overcome the major challenges that face the environmental and human health. To harness potentials of bioengineering and establish a sustainable foundation for green technology, modern scientists and engineers need to be acquainted with the normative questions of science. In addition to acquiring the general principles of scientific research and identifying the intrinsic goals of the endeavour, philosophy of bioengineering exposes bioengineers to both the descriptive ‘how’ questions of the physical world as well as the normative ‘why’ questions of values. Such an interdisciplinary approach is significant, not only for inspiring to acquire the genuine knowledge of the existing world, but also to expose the bioengineers to their ethical and social responsibilities. Besides introducing the conceptual framework of bioengineering, this paper has investigated the three major philosophies that have been dominating the theoretical presuppositions of scientific research method in history. Namely, (i Systems biology approach; (ii Evolutionary biology approach; and (iii Mechanical view approach. To establish the ethical foundation of modern bioengineering, the paper, also has conducted an analytical study on various branches of the emerging discipline of bioscience. The paper has concluded that adopting the interdisciplinary approach in research and education is essential to harness potentials of bioengineering and to establish foundations of green technology. To achieve the final objectives of bioengineering, both the practical and theoretical

    Purpose: Collisions between treatment equipment and patients are potentially catastrophic. Modern technology now commonly involves automated remote motion during imaging and treatment, yet a systematic assessment to identify and mitigate collision risks has yet to be performed. Failure modes and effects analysis (FMEA) is a method of risk assessment that has been increasingly used in healthcare, yet can be resource intensive. This work presents an efficient approach to FMEA to identify collision risks and implement practical interventions within a modern radiation therapy department. Methods: Potential collisions (e.g. failure modes) were assessed for all treatment and simulation rooms by teams consisting of physicists, therapists, and radiation oncologists. Failure modes were grouped into classes according to similar characteristics. A single group meeting was held to identify implementable interventions for the highest priority classes of failure modes. Results: A total of 60 unique failure modes were identified by 6 different teams of physicists, therapists, and radiation oncologists. Failure modes were grouped into four main classes: specific patient setups, automated equipment motion, manual equipment motion, and actions in QA or service mode. Two of these classes, unusual patient setups and automated machine motion, were identified as being high priority in terms severity of consequence and addressability by interventions. The two highest risk classes consisted of 33 failure modes (55% of the total). In a single one hour group meeting, 6 interventions were identified. Those interventions addressed 100% of the high risk classes of failure modes (55% of all failure modes identified). Conclusion: A class-based approach to FMEA was developed to efficiently identify collision risks and implement interventions in a modern radiation oncology department. Failure modes and interventions will be listed, and a comparison of this approach against traditional FMEA methods

That is the reason why the modernization potential is explained as theoretical-hypothetical basis for understanding of contemporary needs for regionalization (as one of the aspects of developmental problems of contemporary societies, and, at the same time, as a knowledge need for critical reconsideration of regionalism (as etatistic mediation in distribution of power of political elites. Sociological approach to the problems of regionalization is a part of sociological research of social development. That is why this problem is one of numerous factors that influence the possibility of a concrete society to reproduce itself. Due to this reason, problems of regionalization cannot be (sociologically explained outside of theoretical perspective of modernization. It means that the problems of regionalization cannot be reduced to (legal and political problem of regionalism, as a problem of state and its territorial and political organization (in the inter-space of local communities and its center, but it calls for broader sociological problematization (because it reflects the characteristics of the modernization of concrete society. In this respect, real problems of legal and political regionalism are situated in less visible structural-historical and social-cultural feature of development of modern societies and their correspondent states; namely beyond regionalism. Since sociological approach to regionalization tries to find out real social-cultural links and relations that make some concrete territorial community specific within a global society, it is necessary in sociological research

    1976-01-01

    Full Text Available Hugo Friedrich's genealogical and normative theory of modern poetry is contrasted with Michel Foucault's essentially static formulations of man's self-creating posture at the centre of a world without transcendence. The role of history and history- making in the modern consciousness is then viewed from the perspective of the early Expressionist poets, Georg Heym (1887-1912 and Georg Trakl (1887-1914. Both writers saw the tradition of Romantic individualism as dead yet persisting in an aimless afterlife, but their responses were antithetical. Trakl, using his personal experience as an emblematic image of the end, reorchestrated the myths and depravities of tradition into a structure that includes its own destruction. Heym's reiterated evocations of sickness and apocalyptic paralysis reduce poetic tradition to the empty rhythm of anonymous individuality.

    Full Text Available Our paper focuses on the relevant theoretical economic approaches that allow us to understand the key elements of cultural values. The paper presents a model envisaged to estimate economic and social impact of modernization on cultural values in modern societies. We employ three indices of social and economic development for each level in Russian Federal districts of Moscow and St. Petersburg in order to reveal their impacts on modernization processes. Our data has been collected via the means of a questionnaire and an opinion poll with the purpose of revealing the value guidelines of society in terms of its modernization. Our results reveal the presence of four relevant levels of value orientations: family orientations, global, work, and personal orientations. Our results demonstrate how modernization is perceived in modern societies, in which spheres it is mostly expressed, and how it influences the society. Moreover, we show the determinants of values within four levels of value orientations. Our findings provide estimations of modern attitudes towards social consciousness in the processes of modernization and reveal basic moral principles that could become a background of new system of values used in modernizing modern societies.

    2009-08-01

    In the recent years, a wide range of metabonomic analytical techniques are widely used in the modern research of traditional Chinese medicine (TCM). At the same time, the international community has attached increasing importance to TCM toxicity problems. Thus, many studies have been implemented to investigate the toxicity mechanisms of TCM. Among these studies, many metabonomic-based methods have been implemented to facilitate TCM toxicity investigation. At present, the most prevailing methods for TCM toxicity research are mainly single analysis techniques using only one analytical means. These techniques include nuclear magnetic resonance (NMR), gas chromatography-mass spectrometry (GC-MS), and liquid chromatography-mass spectrometry (LC-MS), etc.; with these techniques, some favourable outcomes have been gained in the toxic reaction studies of TCM, such as the action target organs assay, the establishment of action pattern, the elucidation of action mechanism and the exploration of action material foundation. However, every analytical technique has its advantages and drawbacks, no existing analytical technique can be versatile. Multi-analysed techniques can partially overcome the shortcomings of single-analysed techniques. Combination of GC-MS and LC-MS metabolic profiling approaches has unravelled the pathological outcomes of aristolochic acid-induced nephrotoxicity, which can not be achieved by single-analysed techniques. It is believed that with the further development of metabonomic analytical techniques, especially multi-analysed techniques, metabonomics will greatly promote TCM toxicity research and be beneficial to the modernization of TCM in terms of extending the application of modern means in the TCM safety assessment, assisting the formulation of TCM safety norms and establishing the international standards indicators.

    The main aim of this paper is to investigate properties of our originally formulated statistical model-based iterative approach applied to the image reconstruction from projections problem which are related to its conditioning, and, in this manner, to prove a superiority of this approach over ones recently used by other authors. The reconstruction algorithm based on this conception uses a maximum likelihood estimation with an objective adjusted to the probability distribution of measured signals obtained from an X-ray computed tomography system with parallel beam geometry. The analysis and experimental results presented here show that our analytical approach outperforms the referential algebraic methodology which is explored widely in the literature and exploited in various commercial implementations.

    In this paper, we provide a simple and modern discussion of rotational superradiance based on quantum field theory. We work with an effective theory valid at scales much larger than the size of the spinning object responsible for superradiance. Within this framework, the probability of absorption by an object at rest completely determines the superradiant amplification rate when that same object is spinning. We first discuss in detail superradiant scattering of spin 0 particles with orbital angular momentum ℓ=1, and then extend our analysis to higher values of orbital angular momentum and spin. Along the way, we provide a simple derivation of vacuum friction — a “quantum torque” acting on spinning objects in empty space. Our results apply not only to black holes but to arbitrary spinning objects. We also discuss superradiant instability due to formation of bound states and, as an illustration, we calculate the instability rate Γ for bound states with massive spin 1 particles. For a black hole with mass M and angular velocity Ω, we find Γ∼(GMμ){sup 7}Ω when the particle’s Compton wavelength 1/μ is much greater than the size GM of the spinning object. This rate is parametrically much larger than the instability rate for spin 0 particles, which scales like (GMμ){sup 9}Ω. This enhanced instability rate can be used to constrain the existence of ultralight particles beyond the Standard Model.

    Rapid detection and identification of microorganisms is a challenging and important aspect in a wide range of fields, from medical to industrial, affecting human lives. Unfortunately, classical methods of microorganism identification are based on time-consuming and labor-intensive approaches. Screening techniques require the rapid and cheap grouping of bacterial isolates; however, modern bioanalytics demand comprehensive bacterial studies at a molecular level. Modern approaches for the rapid identification of bacteria use molecular techniques, such as 16S ribosomal RNA gene sequencing based on polymerase chain reaction or electromigration, especially capillary zone electrophoresis and capillary isoelectric focusing. However, there are still several challenges with the analysis of microbial complexes using electromigration technology, such as uncontrolled aggregation and/or adhesion to the capillary surface. Thus, an approach using capillary electrophoresis of microbial aggregates with UV and matrix-assisted laser desorption ionization time-of-flight MS detection is presented.

    The objective of this study was to develop a novel methodology that enables pig diets to be formulated explicitly for environmental impact objectives using a Life Cycle Assessment (LCA) approach. To achieve this, the following methodological issues had to be addressed: (1) account for environmental impacts caused by both ingredient choice and nutrient excretion, (2) formulate diets for multiple environmental impact objectives and (3) allow flexibility to identify the optimal nutritional composition for each environmental impact objective. An LCA model based on Canadian pig farms was integrated into a diet formulation tool to compare the use of different ingredients in Eastern and Western Canada. By allowing the feed energy content to vary, it was possible to identify the optimum energy density for different environmental impact objectives, while accounting for the expected effect of energy density on feed intake. A least-cost diet was compared with diets formulated to minimise the following objectives: non-renewable resource use, acidification potential, eutrophication potential, global warming potential and a combined environmental impact score (using these four categories). The resulting environmental impacts were compared using parallel Monte Carlo simulations to account for shared uncertainty. When optimising diets to minimise a single environmental impact category, reductions in the said category were observed in all cases. However, this was at the expense of increasing the impact in other categories and higher dietary costs. The methodology can identify nutritional strategies to minimise environmental impacts, such as increasing the nutritional density of the diets, compared with the least-cost formulation.

    In this work, we have developed a novel multiscale computational contact formulation based on the generalized Derjuguin approximation for continua that are characterized by atomistically enriched constitutive relations in order to study macroscopic interaction between arbitrarily shaped deformable continua. The proposed adhesive contact formulation makes use of the microscopic interaction forces between individual particles in the interacting bodies. In particular, the double-layer volume integral describing the contact interaction (energy, force vector, matrix) is converted into a double-layer surface integral through a mathematically consistent approach that employs the divergence theorem and a special partitioning technique. The proposed contact model is formulated in the nonlinear continuum mechanics framework and implemented using the standard finite element method. With no large penalty constant, the stiffness matrix of the system will in general be well-conditioned, which is of great significance for quasi-static analysis. Three numerical examples are presented to illustrate the capability of the proposed method. Results indicate that with the same mesh configuration, the finite element computation based on the surface integral approach is faster and more accurate than the volume integral based approach. In addition, the proposed approach is energy preserving even in a very long dynamic simulation.

  15. Thermodynamic fluctuations within the Gibbs and Einstein approaches

    2000-01-01

    A comparative analysis of the descriptions of fluctuations in statistical mechanics (the Gibbs approach) and in statistical thermodynamics (the Einstein approach) is given. On this basis solutions are obtained for the Gibbs and Einstein problems that arise in pressure fluctuation calculations for a spatially limited equilibrium (or slightly nonequilibrium) macroscopic system. A modern formulation of the Gibbs approach which allows one to calculate equilibrium pressure fluctuations without making any additional assumptions is presented; to this end the generalized Bogolyubov - Zubarev and Hellmann - Feynman theorems are proved for the classical and quantum descriptions of a macrosystem. A statistical version of the Einstein approach is developed which shows a fundamental difference in pressure fluctuation results obtained within the context of two approaches. Both the 'genetic' relation between the Gibbs and Einstein approaches and the conceptual distinction between their physical grounds are demonstrated. To illustrate the results, which are valid for any thermodynamic system, an ideal nondegenerate gas of microparticles is considered, both classically and quantum mechanically. Based on the results obtained, the correspondence between the micro- and macroscopic descriptions is considered and the prospects of statistical thermodynamics are discussed.

    Full Text Available Banks are still using legacy systems as the core of their business is comprised within such sys-tems. Since the technology and client demands are changing rapidly, the banks have to adapt their systems in order to be competitive. The issue is to identify correctly what are the bank users preferences in terms of software reliability and how modern is the system For instance, there are users who enjoy working using the old screen format, and there are users who enjoy working with newer layouts, Web interfaces, and so on. We need also to know the constraints generated by the usage of legacy systems, and how these systems can be improved or replaced. The scope of the article is to present a solution of modernizing a legacy banking system by using a SOA approach. The research is based on the modernization of a legacy system developed in COBOL/400 under IBM iSeries. The modernization process uses a SOA ap-proach using JAVA technologies.

Half of UC patients have inflammation limited to the distal colon (proctitis or proctosigmoiditis that primarily causes symptoms of bloody diarrhea and urgency. Mild-to-moderate distal UC can be effectively treated with topical formulations (rectal suppositories, enemas, or foam of mesalamine or steroids to reduce mucosal inflammation and alleviate symptoms. Enemas or foam formulations adequately reach up to the splenic flexure, have a minimal side-effect ­profile, and induce remission alone or in combination with systemic immunosuppressive therapy. Herein, we compare the efficacy, cost, patient tolerance, and side-effect profiles of steroid and mesalamine rectal formulations in distal UC. Patients with distal mild-to-moderate UC have a remission rate of approximately 75% (NNT =2 after treatment for 6 weeks with mesalamine enemas. Rectal budesonide foam induces remission in 41.2% of patients with mild-to-moderate active distal UC compared to 24% of patient treated with placebo (NNT =5. However, rectal budesonide has better patient tolerance profile compared to enema formulations. Despite its favorable efficacy, safety, and cost profiles, patients and physicians significantly underuse topical treatments for treating distal colitis. This necessitates improved patient education and physician familiarity regarding the indications, effectiveness, and potential financial and tolerability barriers in using rectal formulations.

    The objective of the present investigation was to enhance skin permeation of diclofenac using water-in-oil microemulsion and to elucidate its skin permeation mechanism. The w/o microemulsion formulations were selected based on constructed pseudoternary phase diagrams depending on water solubilization capacity and thermodynamic stability. These formulations were also subjected to physical characterization based on droplet size, viscosity, pH and conductivity. Permeation of diclofenac across rat skin using side-by-side permeation cells from selected w/o microemulsion formulations were evaluated and compared with control formulations. The selected w/o microemulsion formulations were thermodynamically stable, and incorporation of diclofenac sodium into microemulsion did not affect the phase behavior of system. All microemulsion formulations had very low viscosity (11-17 cps) and droplet size range of 30-160 nm. Microemulsion formulations exhibited statistically significant increase in diclofenac permeation compared to oily solution, aqueous solution and oil-Smix solution. Higher skin permeation of diclofenac was observed with low Smix concentration and smaller droplet size. Increase in diclofenac loading in aqueous phase decreased the partition of diclofenac. Diclofenac from the oil phase of microemulsion could directly partition into skin, while diclofenac from the aqueous droplets was carried through skin by carrier effect.

    Groundwater management in China has been facing challenges from both climate change and urbanization and is considered as a national priority nowadays. However, unprecedented uncertainty exists in future scenarios making it difficult to formulate management planning paradigms. In this paper, we apply modern portfolio theory (MPT) to formulate an optimal stage investment of groundwater contamination remediation in China. This approach generates optimal weights of investment to each stage of the groundwater management and helps maximize expected return while minimizing overall risk in the future. We find that the efficient frontier of investment displays an upward-sloping shape in risk-return space. The expected value of groundwater vulnerability index increases from 0.6118 to 0.6230 following with the risk of uncertainty increased from 0.0118 to 0.0297. If management investment is constrained not to exceed certain total cost until 2050 year, the efficient frontier could help decision makers make the most appropriate choice on the trade-off between risk and return.

    In the present study, Cremophor EL free paclitaxel elastic liposomal formulation consisting of soya phosphatidylcholine and biosurfactant sodium deoxycholate was developed and optimized. The toxicological profile, antitumor efficacy and hemolytic toxicity of paclitaxel elastic liposomal formulation in comparison to Cremophor EL based marketed formulation were evaluated. Paclitaxel elastic liposomal formulations were prepared and characterized in vitro, ex-vivo and in vivo. Single dose toxicity study of paclitaxel elastic liposomal and marketed formulation was carried out in dose range of 10, 20, 40, 80, 120, 160 and 200 mg/kg. Cytotoxicity of developed formulation was evaluated using small cell lung cancer cell line (A549). Antitumor activity of developed formulation was compared with the marketed formulation using Cytoselect™ 96-well cell transformation assay. In vivo administration of paclitaxel elastic liposomal formulation into mice showed 6 fold increase in Maximum Tolerated Dose (MTD) in comparison to the marketed formulation. Similarly, LD50 (141.6 mg/kg) was also found to increase significantly than the marketed formulation (16.7 mg/kg). Result of antitumor assay revealed a high reduction of tumor density with paclitaxel elastic liposomal formulation. Reduction in hemolytic toxicity was also observed with paclitaxel elastic liposomal formulation in comparison to the marketed formulation. The carrier based approach for paclitaxel delivery demonstrated significant reduction in toxicity as compared to the Cremophor EL based marketed formulation following intra-peritoneal administration in mice model. The reduced toxicity and enhanced anti-cancer activity of elastic liposomal formulation strongly indicate its potential for safe and effective delivery of paclitaxel.

    Many classrooms in higher education still rely on a transformative approach to teaching where students attend lectures and earn course grades through examination. In the modern age, traditional lectures are argued by some as obsolete and do not address the learning needs of today’s students. An emerging pedagogical approach is the concept of the flipped classroom. The flipped classroom can simply be described as students viewing asynchronous video lectures on their own and then engaging in active learning during scheduled class times. In this study, we examined the flipped classroom teaching environment on student learning gains in an Introduction to Equine Science course. Students (n = 130) were asked to view 7.5 h of recorded lectures divided into 8 learning modules, take online quizzes to enforce lecture viewing, take 3 in-class exams, and prepare to participate in active learning during scheduled class times. Active learning approaches included individual activities, paired activities, informal small groups, and large group activities. When compared to students in the traditional lecture format in earlier years, students in the flipped format scored higher on all 3 exams (P flipped format students were asked to take the Cornell Critical Thinking Exam (version X). Scores improved from the pretest (50.8 ± 0.57) to the posttest (54.4 ± 0.58; P flipped course, no correlations were found with student performance and interactions with online content. Students were asked in class to evaluate their experiences based on a 5-point Likert scale: 1 (strongly disagree) to 5 (strongly agree). The flipped classroom was ranked as an enjoyable learning experience with a mean of 4.4 ± 0.10, while students responded positively to other pointed questions. In formal course evaluations, flipped format students ranked the following higher (P flipped classroom proved to be a positive learning experience for students.

    The present investigation focused on developing, optimizing, and evaluating a novel liposome-loaded nail lacquer formulation for increasing the transungual permeation flux of terbinafine HCl for efficient treatment of onychomycosis. A three-factor, three-level, Box-Behnken design was employed for optimizing process and formulation parameters of liposomal formulation. Liposomes were formulated by thin film hydration technique followed by sonication. Drug to lipid ratio, sonication amplitude, and sonication time were screened as independent variables while particle size, PDI, entrapment efficiency, and zeta potential were selected as quality attributes for liposomal formulation. Multiple regression analysis was employed to construct a second-order quadratic polynomial equation and contour plots. Design space (overlay plot) was generated to optimize a liposomal system, with software-suggested levels of independent variables that could be transformed to desired responses. The optimized liposome formulation was characterized and dispersed in nail lacquer which was further evaluated for different parameters. Results depicted that the optimized terbinafine HCl-loaded liposome formulation exhibited particle size of 182 nm, PDI of 0.175, zeta potential of -26.8 mV, and entrapment efficiency of 80%. Transungual permeability flux of terbinafine HCl through liposome-dispersed nail lacquer formulation was observed to be significantly higher in comparison to nail lacquer with a permeation enhancer. The developed formulation was also observed to be as efficient as pure drug dispersion in its antifungal activity. Thus, it was concluded that the developed formulation can serve as an efficient tool for enhancing the permeability of terbinafine HCl across human nail plate thereby improving its therapeutic efficiency.

    Quantum and classical mechanics are two conceptually and mathematically different theories of physics, and yet they do use the same concept of classical mass that was originally introduced by Newton in his formulation of the laws of dynamics. In this paper, physical consequences of using the classical mass by both theories are explored, and a novel approach that allows formulating fundamental (Galilean invariant) theories of waves and particles without formally introducing the classical mass is presented. In this new formulation, the theories depend only on one common parameter called 'wave mass', which is deduced from experiments for selected elementary particles and for the classical mass of one kilogram. It is shown that quantum theory with the wave mass is independent of the Planck constant and that higher accuracy of performing calculations can be attained by such theory. Natural units in connection with the presented approach are also discussed and justification beyond dimensional analysis is given for the particular choice of such units.

    Full Text Available In the article the analysis of experience and best practices of Europe and the world regarding the methods and tools of risk management in customs affairs. In accordance with the requirements of the Kyoto Convention the risk management is the main basic principle of modern customs control methods, which allows optimal use of resources of customs bodies, without reducing the effectiveness of customs controls, and exempt the majority of foreign trade operators from unnecessary bureaucratic control. Procedures based on risk management, concentrate customs control on areas, where there is the greatest risk, allowing the bulk of goods and individuals relatively free to pass the checkpoint at the customs border Special attention is paid to the principles and methods of risk management and their impact on the simplification of customs procedures through the use of risk-based thinking. The paper discusses the problems concerning the application and implementation of modern risk management techniques in customs procedures subject to the requirements of international standards ISO for the quality management system and risk management based on risk-based thinking.

    Full Text Available A strategy for the second modernization raises, beyond objectives, a series of epistemicresponsibilities. It is known that modernization stemming from the Enlightment had, among other things,the pretense that it is a project which is self-legitimating. Its profound rationales are the only justification.Referential self-centering proved to be the one that made possible a practice of the new. Modernizationhaving the function of renouncing myth – meaning an eliminatory formula for the past – and thefixation in the opportunity and potentiality of the present, seemed to close an insoluble but extremelyengrossing problem: that of a propensity towards utopia, of the risky escape towards the future. Thetraditionalization of the new constitutes a support for the daring to break out of the captivity of themoment.Modernization becomes the experience of combining the new which, thus, creates a succession ofpresent times. The future is no longer the result of fantasy, but a system’s direct expression to combine thenew. Therefore the future is an option for one or another model of the present, often tested previouslysomewhere else. In a non-metaphysical way, the future can be seen, touched, tried, lived by simplegeographical movement. The sense of evolution has de-temporalized taking the form of the concomitant,parallel, enclosed, neighboring space. We just have to be in the trend, to evolve in the context.Globalization defines the context and its conception – as a project of the second modernity – showsus the trends. The problem is how to understand the context in order to find the sense of the trend. Are wethe load the sense with the values of the first modernity or will we have to turn to the values of anothermodernity? Why do we have to move away from the significance of the processes which made up the firstmodernity?

    Full Text Available Background. Thrombocytopenia per se is one of the hematological diseases, which demands the repeated thrombocytes infusion. The last tendencies in the management of this disease show the enhanced amount of the necessary thrombocytes doses for treatment and the worldwide trend for the declining of donors. Considerably to these facts the new approaches for the thrombocytopenia treatment have been organized within last two decades. One of them is the finding of the safe, appropriate and effective growth factor for platelets, which could significantly improve the level of thrombocytes. The article describes the case of refractory ITP management in pregnancy. ITP diagnosed at 26 weeks of gestation, the platelet number at the time of diagnostics 20000.

    2012-01-01

    A Modern Theory of Random Variation is a new and radical re-formulation of the mathematical underpinnings of subjects as diverse as investment, communication engineering, and quantum mechanics. Setting aside the classical theory of probability measure spaces, the book utilizes a mathematically rigorous version of the theory of random variation that bases itself exclusively on finitely additive probability distribution functions. In place of twentieth century Lebesgue integration and measure theory, the author uses the simpler concept of Riemann sums, and the non-absolute Riemann-type integration of Henstock. Readers are supplied with an accessible approach to standard elements of probability theory such as the central limmit theorem and Brownian motion as well as remarkable, new results on Feynman diagrams and stochastic integrals. Throughout the book, detailed numerical demonstrations accompany the discussions of abstract mathematical theory, from the simplest elements of the subject to the most complex. I...

    International Nuclear Information System (INIS)

    Leiter, D.

    1980-01-01

    By expressing classical electron theory in terms of 'charge-field' functional structures, it is shown that a finite formulation of the classical electrodynamics of point charges emerges in a simple and elegant fashion. This is used to construct a 'charge-field' quantum electrodynamic theory. It is found that interacting photon states are generated as a secondary manifestation of electron-positron quantization, and do not require the usual 'free' canonical quantization scheme. The possibility is discussed that this approach may lead to a better formulation of quantum electrodynamics in the Heisenberg picture and suggests a crucial experimental test to distinguish this new 'charge-field' quantum electrodynamics 'QEMED' from the standard QED formulation. Specifically QEMED predicts that the 'Einstein principle of separability' should be found to be valid for correlated photon polarization measurements, in which the polarizers are changed more rapidly than a characteristic photon travel time. Such an experiment (Aspect 1976) can distinguish between QEMED and QED in a complete and clear-cut fashion. (U.K.)

The Simulator has reached a continuous high availability of operation throughout the years due to specialized hardware and software support from KSG maintenance team. Nevertheless, D1-Simulator largely reveals limitations with respect to computer capacity and spares and suffers progressively from the non-availability of hardware replacement materials. In order to ensure long term maintainability within the framework of the consensus on nuclear energy, a 2-years refurbishing program has been launched by KWB focusing on quality and budgetary aspects. The so-called D1+ Simulator project is based on the re-use of validated data from existing simulators. Allowing for flexible project management methods, the project outlines a cost and risk optimized approach to Nuclear Power Plant (NPP) Simulator modernization. D1+ Simulator is being built by KSG/GfS in close collaboration with KWB and the simulator vendor THALES by re-using a modern hardware and software development environment from D56-Simulator, used by Kernkraftwerk Obrigheim (KWO) before its decommissioning in 2005. The Simulator project, launched in 2004, is expected to be completed by end of 2006. (author)

  2. Langevin formulation of quantum dynamics

    1989-03-01

    We first show that nonrelativistic quantum mechanics formulated at imaginary-(h/2 π) can formally be viewed as the Fokker-Planck description of a frictionless brownian motion, which occurs (in general) in an absorbing medium. We next offer a new formulation of quantum mechanics, which is basically the Langevin treatment of this brownian motion. Explicitly, we derive a noise-average representation for the transition probability W(X'',t''|X',t'), in terms of the solutions to a Langevin equation with a Gaussian white-noise. Upon analytic continuation back to real-(h/2 π),W(X'',t''|X',t') becomes the propagator of the original Schroedinger equation. Our approach allows for a straightforward application to quantum dynamical problems of the mathematical techniques of classical stochastic processes. Moreover, computer simulations of quantum mechanical systems can be carried out by using numerical programs based on the Langevin dynamics. (author). 19 refs, 1 tab

    The chlorophyll concentration of a water body is an important proxy for representing the phytoplankton biomass. Its estimation from multi or hyper-spectral remote sensing data in natural waters is generally achieved by using (i) the waveband ratioing in two or more bands in the blue-green or (ii) by using a combination of the radiance peak position and magnitude in the red-near-infrared (NIR) spectrum. The blue-green ratio algorithms have been extensively used with satellite ocean color data to investigate chlorophyll distributions in open ocean and clear waters and the application of red-NIR algorithms is often restricted to turbid productive water bodies. These issues present the greatest obstacles to our ability to formulate a modern robust method suitable for quantitative assessments of the chlorophyll concentration in a diverse range of water types. The present study is focused to investigate the normalized water-leaving radiance spectra in the visible and NIR region and propose a robust algorithm (Generalized ABI, GABI algorithm) for chlorophyll concentration retrieval based on Algal Bloom index (ABI) which separates phytoplankton signals from other constituents in the water column. The GABI algorithm is validated using independent in-situ data from various regional to global waters and its performance is further evaluated by comparison with the blue-green waveband ratios and red-NIR algorithms. The results revealed that GABI yields significantly more accurate chlorophyll concentrations (with uncertainties less than 13.5%) and remains more stable in different waters types when compared with the blue-green waveband ratios and red-NIR algorithms. The performance of GABI is further demonstrated using HICO images from nearshore turbid productive waters and MERIS and MODIS-Aqua images from coastal and offshore waters of the Arabian Sea, Bay of Bengal and East China Sea.

  4. Drug Solubility in Fatty Acids as a Formulation Design Approach for Lipid-Based Formulations: A Technical Note.

    Lipid-based drug delivery systems have been intensively investigated as a means of delivering poorly water-soluble drugs. Upon ingestion, the lipases in the gastrointestinal tract digest lipid ingredients, mainly triglycerides, within the formulation into monoglycerides and fatty acids. While numerous studies have addressed the solubility of drugs in triglycerides, comparatively few publications have addressed the solubility of drugs in fatty acids, which are the end product of digestion and responsible for the solubility of drug within mixed micelles. The objective of this investigation was to explore the solubility of a poorly water-soluble drug in fatty acids and raise the awareness of the importance of drug solubility in fatty acids. The model API (active pharmaceutical ingredient), a weak acid, is considered a BCS II compound with an aqueous solubility of 0.02 μg/mL and predicted partition coefficient >7. The solubility of API ranged from 120 mg/mL to over 1 g/mL in fatty acids with chain lengths across the range C18 to C6. Hydrogen bonding was found to be the main driver of the solubilization of API in fatty acids. The solubility of API was significantly reduced by water uptake in caprylic acid but not in oleic acid. This report demonstrates that solubility data generated in fatty acids can provide an indication of the solubility of the drug after lipid digestion. This report also highlights the importance of measuring the solubility of drugs in fatty acids in the course of lipid formulation development.

    Flinn, Lucinda; Braham, Louise; das Nair, Roshan

    2015-09-01

    This systematic literature review investigated the inter-rater and test-retest reliability of case formulations. We considered the reliability of case formulations across a range of theoretical modalities and the general quality of the primary research studies. A systematic search of five electronic databases was conducted in addition to reference list trawling to find studies that assessed the reliability of case formulation. This yielded 18 studies for review. A methodological quality assessment tool was developed to assess the quality of studies, which informed interpretation of the findings. Results indicated inter-rater reliability mainly ranging from slight (.1-.4) to substantial (.81-1.0). Some studies highlighted that training and increased experience led to higher levels of agreement. In general, psychodynamic formulations appeared to generate somewhat increased levels of reliability than cognitive or behavioural formulations; however, these studies also included methods that may have served to inflate reliability, for example, pooling the scores of judges. Only one study investigated the test-retest reliability of case formulations yielding support for the stability of formulations over a 3-month period. Reliability of case formulations is varied across a range of theoretical modalities, but can be improved; however, further research is required to strengthen our conclusions. Clinical implications: The findings from the review evidence some support for case formulation being congruent with the scientist-practitioner approach. The reliability of case formulation is likely to be improved through training and clinical experience. Limitations: The broad inclusion criteria may have introduced heterogeneity into the sample, which may have affected the results. Studies reviewed were limited to peer-reviewed journal articles written in the English language, which may represent a source of publication and selection bias. © 2014 The British Psychological Society.

    Diclofenac (DF) was first synthesized in the 1960's and is currently available as ophthalmic, oral, parenteral, rectal and skin preparations. This review focuses on the administration of DF to the skin. As a member of the non-steroidal anti-inflammatory (NSAID) group of drugs the primary indications of DF are for the management of inflammation and pain but it is also used to treat actinic keratosis. The specific aims of this paper are to: (i) provide an overview of the pharmacokinetics and metabolism of DF following oral and topical administration; (ii) examine critically the various formulation approaches which have been investigated to enhance dermal delivery of DF; and (iii) identify new formulation strategies for enhanced DF skin penetration.

    2010-01-01

    We present a superspace formulation of the D=3, N=4, 5 superconformal Chern-Simons Matter theories, with matter supermultiplets valued in a symplectic 3-algebra. We first construct an N=1 superconformal action and then generalize a method used by Gaitto and Witten to enhance the supersymmetry from N=1 to N=5. By decomposing the N=5 supermultiplets and the symplectic 3-algebra properly and proposing a new superpotential term, we construct the N=4 superconformal Chern-Simons matter theories in terms of two sets of generators of a (quaternion) symplectic 3-algebra. The N=4 theories can also be derived by requiring that the supersymmetry transformations are closed on-shell. The relationship between the 3-algebras, Lie superalgebras, Lie algebras, and embedding tensors (proposed in [E. A. Bergshoeff, O. Hohm, D. Roest, H. Samtleben, and E. Sezgin, J. High Energy Phys. 09 (2008) 101.]) is also clarified. The general N=4, 5 superconformal Chern-Simons matter theories in terms of ordinary Lie algebras can be re-derived in our 3-algebra approach. All known N=4, 5 superconformal Chern-Simons matter theories can be recovered in the present superspace formulation for super-Lie algebra realization of symplectic 3-algebras.

The aim of the present study was to prepare gefitinib nanosuspension. Gefitinib was encapsulated in Eudragit® RL100 and then dispersed in stabilizer solution, polyvinyl alcohol, and polyvinylpyrrolidone K30. Nanosuspension was prepared by using homogenization and ultrasonication techniques. The quality by design approach was also used in the study to understand the effect of critical material attributes (CMAs and critical processing parameters (CPPs on critical quality attributes and to improve the quality and safety of formulation. To study the effect of CMAs and CPPs, 23 full factorial design was applied. The particle size, polydispersity index, and zeta potential of the optimized solution were 248.20 nm, 0.391, and -5.62 mV, respectively. Drug content of the optimized nanoformulation was found to be 87.74%±1.19%. Atomic force microscopy studies of the optimized formulation confirmed that the prepared nanoparticles are smooth and spherical in nature. In vitro cytotoxicity studies of the nanosuspension on Vero cell line revealed that the formulation is nontoxic. The gefitinib nanosuspension released 60.03%±4.09% drug over a period of 84 h, whereas standard drug dispersion released only 10.39%±3.37% drug in the same duration.

  18. Protecting the fast breeders: Problem formulation and effects analysis

    International Nuclear Information System (INIS)

    Oughton, D.H.

    2003-01-01

    Recent debates on protection of the environment from ionising radiation have reached reasonable agreement over the ethical and philosophical basis of environmental protection and a recognition that a practical system of protection will need to support (at a minimum) the principles of sustainable development, biodiversity, and conservation. However, there is still some controversy over the use of dose assessment tools within risk evaluation and management. The paper uses the case of the Dounreay 'radioactive rabbits' to discuss the advantages and limitations of proposed systems, focusing primarily on the interaction between ecological risk assessment (ERA) and the reference flora and fauna approach. It concludes that the reference approach is a valuable tool for the analysis of environmental effects, but that there is a problem if it becomes the driving force of the protection framework. In particular, there is a need for a clearer focus on non-technical issues within the problem formulation stage of ERA, particularly the social, ethical, political and economic issues, and there should be a strong commitment to stakeholder involvement at this stage. The problem formulation stage should identify the relevant assessment tools; the assessment tool should dictate neither the problem formulation nor the risk management. (author)

    The Central Interim Storage for radioactive waste in Brinje, being put into operation in 1986, needs refurbishment and modernization in order to meet the up-to-date operational and safety requirements and to ensure the normal and undisturbed acceptance of radioactive waste from small producers in the future. Because of the waste, being already stored in the storage, the lack of reprocessing capacities and the lack of auxiliary room, the refurbishment and modernization is a complex problem, which needs to be addressed with care. The plan of refurbishment and modernization requires an integral approach, covering all different aspects of renewal and reconstruction. The implementation plan, however, must be based on the actual state of the storage and real conditions for the implementations: from technical to financial. In this paper the project for refurbishment and modernization of the storage, and some activities that have already been implemented, are presented.(author)

    Full Text Available The purpose of this paper is to thoroughly analyse the concept of multichannel strategy, focussing on retail, to enable the academic community and marketers to better understand its advantages and disadvantages. This paper presents a comprehensive literature review and financial data analysis. The authors have analysed the financial data of 88 retail companies in the 2007 to 2014 period, and have proven that the importance of multichannel strategy has grown with the emergence of e-commerce. The main hypothesis is that the multichannel concept dominates modern marketing channels because it is widely accepted and provides superior financial performance. Multichannel retailing is definitely a winning concept, if adequately implemented. However, wrongly implemented it can negatively influence business performance.

  4. Modern Prodrug Design for Targeted Oral Drug Delivery

    Directory of Open Access Journals (Sweden)

    Arik Dahan

    2014-10-01

    Full Text Available The molecular information that became available over the past two decades significantly influenced the field of drug design and delivery at large, and the prodrug approach in particular. While the traditional prodrug approach was aimed at altering various physiochemical parameters, e.g., lipophilicity and charge state, the modern approach to prodrug design considers molecular/cellular factors, e.g., membrane influx/efflux transporters and cellular protein expression and distribution. This novel targeted-prodrug approach is aimed to exploit carrier-mediated transport for enhanced intestinal permeability, as well as specific enzymes to promote activation of the prodrug and liberation of the free parent drug. The purpose of this article is to provide a concise overview of this modern prodrug approach, with useful successful examples for its utilization. In the past the prodrug approach used to be viewed as a last option strategy, after all other possible solutions were exhausted; nowadays this is no longer the case, and in fact, the prodrug approach should be considered already in the very earliest development stages. Indeed, the prodrug approach becomes more and more popular and successful. A mechanistic prodrug design that aims to allow intestinal permeability by specific transporters, as well as activation by specific enzymes, may greatly improve the prodrug efficiency, and allow for novel oral treatment options.

    Full Text Available We reviewed 153 peer-reviewed sources to provide identification of modern supply chain management techniques and exploration of supply chain modeling, to offer decision support to managers. Ultimately, the review is intended to assist member-companies of supply chains, mainly producers, improve their current management approaches, by directing them to studies that may be suitable for direct application to their supply chains and value chains for improved efficiency and profitability. We found that information on supply chain management and modeling techniques in general is available. However, few Canadian-based published studies exist regarding a demand-driven modeling approach to value/supply chain management for wood pellet production. Only three papers were found specifically on wood pellet value chain analysis. We propose that more studies should be carried out on the value chain of wood pellet manufacturing, as well as demand-driven management and modeling approaches with improved demand forecasting methods.

    A bilayer tablet, which consisted of telmisartan and amlodipine besylate, was formulated based on a Quality by Design (QbD) approach. The control and response factors were determined based on primary knowledge and the target values of the control tablet (Twynsta ® ). A D-optimal mixture design was used to obtain the optimal formulations in terms of D-mannitol, crospovidone, and MCC for the telmisartan layer, and CCM-Na, PVP K25, and Prosolv for the amlodipine layer. The quantitative effects of the different formulation factors on the response factors were accurately predicted using the equations of best fit and a strong linearity was observed between the predicted and actual values of the response factors. The optimized bilayer tablet was obtained using a numeric optimization technique and was characterized compared with a control (Twynsta ® ) by using various physical evaluations and in vivo pharmacokinetic parameters. The physical stability of Telmiduo ® was greater than that of Twynsta ® owing to the improvement of formulation factors. The in vivo pharmacokinetic parameters suggested that Telmiduo ® might have pharmaceutical equivalence and bioequivalence with Twynsta ® . Therefore, the bilayer tablet that consisted of telmisartan and amlodipine besylate could be produced using a more economical and simpler method than that used to produce Twynsta ® . Moreover, the suitability of QbD for effective product development in the pharmaceutical industry was shown. Copyright © 2017 Elsevier B.V. All rights reserved.

    The use of lipid formulations has greatly improved the ability to effectively deliver oligonucleotides and has been instrumental in the rapid expansion of therapeutic development programs using oligonucleotide drugs. However, the development of such complex multicomponent therapeutics requires the implementation of unique, scientifically sound approaches to the nonclinical development of these drugs, based upon a hybrid of knowledge and experiences drawn from small molecule, protein, and oligonucleotide therapeutic drug development. The relative paucity of directly applicable regulatory guidance documents for oligonucleotide therapeutics in general has resulted in the generation of multiple white papers from oligonucleotide drug development experts and members of the Oligonucleotide Safety Working Group (OSWG). The members of the Formulated Oligonucleotide Subcommittee of the OSWG have utilized their collective experience working with a variety of formulations and their associated oligonucleotide payloads, as well as their insights into regulatory considerations and expectations, to generate a series of consensus recommendations for the pharmacokinetic characterization and nonclinical safety assessment of this unique class of therapeutics. It should be noted that the focus of Subcommittee discussions was on lipid nanoparticle and other types of particulate formulations of therapeutic oligonucleotides and not on conjugates or other types of modifications of oligonucleotide structure intended to facilitate delivery.

    We take it for granted that we can use words properly ? appropriately, meaningfully, even decorously. And yet it is very difficult to justify or explain what makes a particular use ""proper."" Given that properness is determined by the unpredictable vagaries of unrepeatable contexts, it is impossible to formulate an absolute rule which tells what is proper in every situation. In its four case studies of texts by Ascham, Puttenham, Mulcaster, and the first English dictionary writers, Rules of Use shows the way in which early modern pedagogues attempted to articulate such a rule whilst being min

    Honey, known for centuries as a topical treatment for a wide range of wounds, has recently known a revival in modern wound care. The objective of this systematic review is to evaluate the available evidence and the role of honey in contemporary wound care. The search strategy was developed in the databases PubMed and ISI Web of Science. Fifty-five studies of any design, evaluating the use of honey in human burns, ulcers and other wounds, written in English, French, German or Dutch were eligible for inclusion. In all three wound categories honey seems to be a dressing with wound healing stimulating properties. In burns there is also evidence for its antibacterial capacity. In general, honey is also been mentioned to have deodorizing, debridement, anti-inflammatory and wound pain reducing properties, although the evidence for these properties is rather limited. Many of the included studies have methodological problems, and the quality of certain studies is low, making it difficult to formulate conclusive guidelines. This review reveals several gaps in the research of honey in modern wound care, and recommendations are suggested for future research. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

    Full Text Available Objective. To familiarize the doctors with diagnostic criteria and modern comprehensive approach to the treatment of children with Prader-Willie syndrome. The problems of treatment with growth hormone, social integration of patients were stressed, a clinical case from practice is presented. The analysis of the scientific literature of leading foreign and domestic authors has been carried out. The article presents the current approaches to early diagnosis based on large and small diagnostic criteria already at the first months of life, indications for molecular-genetic testing by fish-method to detect microdeletions of chromosome 15. A case of Prader-Willi syndrome demonstrates the typical clinical manifestations, the need for a multidisciplinary approach and continuous monitoring of patients. Conclusions. Prader-Willi syndrome has characteristic features that can be detected in most patients during the first six months of life, which will made it possible to carry out timely correction of metabolic and hormonal disorders and to improve quality of life. To clarify the diagnosis, genetic testing, which today became available in most regions of Ukraine, is successfully performed. The question of supporting hormone therapy that enables to adjust significantly the phenotype of patients with Prader-Willi syndrome, providing adequate physical development, is still open. Long-term use of recombinant growth hormone can prevent a number of complications characteristic of the syndrome, and to improve the quality of life for patients in the future.

  14. Principles of ration formulation for ruminants

    International Nuclear Information System (INIS)

    Jayasuriya, M.C.N.

    2002-01-01

    Feeding standards as practiced in developed countries could be misleading when non-conventional feed resources are used in formulating rations for ruminant livestock in developing countries. They tend to reject the poor quality feeds that are available in vast quantities. The non-availability of good quality forage throughout the year and the need to optimise the efficiency of utilisation of locally available feed resources have lead to the application of basic nutritional principles when considering ration formulation. The alternative approach to the use of feeding standards would be to ensure that the production system matches the available resources. The development of feed supplementation strategies based on locally available feed resources require the understanding of the relative roles and nutrient needs of the two-compartment system represented by the micro-organisms in the rumen and the host animal.

  15. A modern neuroscience approach to chronic spinal pain: combining pain neuroscience education with cognition-targeted motor control training.

    Nijs, Jo; Meeus, Mira; Cagnie, Barbara; Roussel, Nathalie A; Dolphens, Mieke; Van Oosterwijck, Jessica; Danneels, Lieven

    2014-05-01

    Chronic spinal pain (CSP) is a severely disabling disorder, including nontraumatic chronic low back and neck pain, failed back surgery, and chronic whiplash-associated disorders. Much of the current therapy is focused on input mechanisms (treating peripheral elements such as muscles and joints) and output mechanisms (addressing motor control), while there is less attention to processing (central) mechanisms. In addition to the compelling evidence for impaired motor control of spinal muscles in patients with CSP, there is increasing evidence that central mechanisms (ie, hyperexcitability of the central nervous system and brain abnormalities) play a role in CSP. Hence, treatments for CSP should address not only peripheral dysfunctions but also the brain. Therefore, a modern neuroscience approach, comprising therapeutic pain neuroscience education followed by cognition-targeted motor control training, is proposed. This perspective article explains why and how such an approach to CSP can be applied in physical therapist practice.

    Over the past half-century, optimal power flow (OPF) has become one of the most important and widely studied nonlinear optimization problems. In general, OPF seeks to optimize the operation of electric power generation, transmission, and distribution networks subject to system constraints and control limits. Within this framework, however, there is an extremely wide variety of OPF formulations and solution methods. Moreover, the nature of OPF continues to evolve due to modern electricity markets and renewable resource integration. In this two-part survey, we survey both the classical and recent OPF literature in order to provide a sound context for the state of the art in OPF formulation and solution methods. The survey contributes a comprehensive discussion of specific optimization techniques that have been applied to OPF, with an emphasis on the advantages, disadvantages, and computational characteristics of each. Part I of the survey (this article) provides an introduction and surveys the deterministic optimization methods that have been applied to OPF. Part II of the survey examines the recent trend towards stochastic, or non-deterministic, search techniques and hybrid methods for OPF. (orig.)

  18. Efficacy of a modern neuroscience approach versus usual care evidence-based physiotherapy on pain, disability and brain characteristics in chronic spinal pain patients: protocol of a randomized clinical trial

    Science.gov (United States)

    2014-01-01

    Background Among the multiple conservative modalities, physiotherapy is a commonly utilized treatment modality in managing chronic non-specific spinal pain. Despite the scientific progresses with regard to pain and motor control neuroscience, treatment of chronic spinal pain (CSP) often tends to stick to a peripheral biomechanical model, without targeting brain mechanisms. With a view to enhance clinical efficacy of existing physiotherapeutic treatments for CSP, the development of clinical strategies targeted at ‘training the brain’ is to be pursued. Promising proof-of-principle results have been reported for the effectiveness of a modern neuroscience approach to CSP when compared to usual care, but confirmation is required in a larger, multi-center trial with appropriate evidence-based control intervention and long-term follow-up. The aim of this study is to assess the effectiveness of a modern neuroscience approach, compared to usual care evidence-based physiotherapy, for reducing pain and improving functioning in patients with CSP. A secondary objective entails examining the effectiveness of the modern neuroscience approach versus usual care physiotherapy for normalizing brain gray matter in patients with CSP. Methods/Design The study is a multi-center, triple-blind, two-arm (1:1) randomized clinical trial with 1-year follow-up. 120 CSP patients will be randomly allocated to either the experimental (receiving pain neuroscience education followed by cognition-targeted motor control training) or the control group (receiving usual care physiotherapy), each comprising of 3 months treatment. The main outcome measures are pain (including symptoms and indices of central sensitization) and self-reported disability. Secondary outcome measures include brain gray matter structure, motor control, muscle properties, and psychosocial correlates. Clinical assessment and brain imaging will be performed at baseline, post-treatment and at 1-year follow-up. Web

    2006-01-01

    Full Text Available Conventionally, the story of musical modernism has been told in terms of a catastrophic break with the (tonal past and the search for entirely new techniques and modes of expression suitable to a new age. The resulting notion of a single, linear, modernist mainstream (predicated on the basis of a Schoenbergian model of musical progress has served to conceal a more subtle relationship between past and present. Increasingly, it is being recognized that there exist many modernisms and their various identities are forged from a continual renegotiation between past and present, between tradition(s and the avant-garde. This is especially relevant when attempting to discuss the reception of modernism outside central Europe, where the adoption of (Germanic avant-garde attitudes was often interpreted as being "unpatriotic". The case of Great Britain is examined in detail: Harrison Birtwistle’s opera The Mask of Orpheus (1973–83 forms the focus for a wider discussion of modernism within the context of late/post-modern thought.

    Full Text Available Enteral nutrition is a method best adjusted to human physiology for correcting disorders of homeostasis in the postoperative period. Untimely and inadequate correction of these disorders may fatally affect a child’s health and rates of the child’s further development. Understanding the laws of stress response generation is important in selecting an optimal nutritive support in the postoperative period. It is necessary to take account of neuro-endocrine-immune response, changing metabolism and an impaired function of the gastrointestinal tract. Modern methods of diagnostics and treatment make it possible to resolve most of the arising issues, but it requires physicians to take a comprehensive approach and have knowledge in many areas of theoretical and practical medicine.

  3. Statistical formulation of gravitational radiation reaction

    International Nuclear Information System (INIS)

    Schutz, B.F.

    1980-01-01

    A new formulation of the radiation-reaction problem is proposed, which is simpler than alternatives which have been used before. The new approach is based on the initial-value problem, uses approximations which need be uniformly valid only in compact regions of space-time, and makes no time-asymmetric assumptions (no a priori introduction of retarded potentials or outgoing-wave asymptotic conditions). It defines radiation reaction to be the expected evolution of a source obtained by averaging over a statistical ensemble of initial conditions. The ensemble is chosen to reflect one's complete lack of information (in real systems) about the initial data for the radiation field. The approach is applied to the simple case of a weak-field, slow-motion source in general relativity, where it yields the usual expressions for radiation reaction when the gauge is chosen properly. There is a discussion of gauge freedom, and another of the necessity of taking into account reaction corrections to the particle-conservation equation. The analogy with the second law of thermodynamics is very close, and suggests that the electromagnetic and thermodynamic arrows of time are the same. Because the formulation is based on the usual initial-value problem, it has no spurious ''runaway'' solutions

  4. Two different formulations of the heavy quark effective theory

    International Nuclear Information System (INIS)

    Balk, S.; Ilakovac, A.; Koerner, J.G.; Pirjol, D.

    1994-01-01

    We point out that there exist two different formulations of the Heavy Quark Effective Theory (HQET). The one formulation of HQET was mostly developed at Harvard and involves the use of the equation of motion to eliminate the small components of the heavy quark field. The second formulation, developed in Mainz, involves a series of Foldy-Wouthuysen-type field transformations which diagonalizes the heavy quark Lagrangian in terms of an effective quark and antiquark sector. Starting at O(1/m Q 2 ) the two formulations are different in that their effective Lagrangians, their effective currents, and their effective wave functions differ. However, when these three differences are properly taken into account, the two alternative formulations lead to identical transition or S-matrix elements. This is demonstrated in an explicit example at O(1/m Q 2 ). We point to an essential difficulty of the Harvard HQET in that the Harvard effective fields are not properly normalized starting at order O(1/m Q 2 ). We provide explicit higher order expressions for the effective fields and the Lagrangian in the Mainz approach, and write down an O(1/m Q 2 ) nonabelian version of the Pauli equation for the heavy quark effective field.

  6. Random path formulation of nonrelativistic quantum mechanics

    International Nuclear Information System (INIS)

    Roncadelli, M.

    1993-01-01

    Quantum amplitudes satisfy (almost) the same calculus that probabilities obey in the theory of classical stochastic diffusion processes. As a consequence of this structural analogy, a new formulation of (nonrelativistic) quantum mechanics naturally arises as the quantum counterpart of the Langevin description of (classical) stochastic diffusion processes. Quantum fluctuations are simulated here by a Fresnel white noise (FWN), which is a (real) white noise with imaginary diffusion constant, whose functional (pseudo) measure yields the amplitude distribution for its configurations. Central to this approach is the idea that classical dynamical trajectories in configuration space are perturbed by the FWN. Hence, a single (arbitrary) classical dynamical path gets replaced by a family of quantum random paths (QRPs) - one for each FWN sample - all originating from the same space-time point (x', t'). The QRPs are the basic objects of the present formulation and are given by a Langevin equation with the FWN, whose drift is controlled by a (arbitrary) solution to the classical Hamilton-Jacobi equation. So, our approach is manifestly based on classical dynamics. Now, a transition amplitude is associated with each QRP: it gives the amplitude that a particle starting from (x', t') will reach (x'', t'') by travelling just along the considered QRP. The quantum mechanical propagator (x'', t'' modul x', t') then emerges as the FWN average of the transition amplitude along a QRP. Thus, quantum mechanics looks like classical mechanics as perturbed by the FWN. The general structure of this formulation is discussed in detail, along with some practical and conceptual implications. (author). 14 refs

  7. A comparative study of modern and fossil cone scales and seeds of conifers: A geochemical approach

    1997-01-01

    Modern cone scales and seeds of Pinus strobus and Sequoia sempervirens, and their fossil (Upper Miocene, c. 6 Mar) counterparts Pinus leitzii and Sequoia langsdorfi have been studied using pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), electron-microprobe and scanning electron microscopy. Microscopic observations revealed only minor microbial activity and high-quality structural preservation of the fossil material. The pyrolysates of both modern genera showed the presence of ligno-cellulose characteristic of conifers. However, the abundance of (alkylated)phenols and 1,2-benzenediols in modern S. sempervirens suggests the presence of non-hydrolysable tannins or abundant polyphenolic moieties not previously reported in modern conifers. The marked differences between the pyrolysis products of both modern genera are suggested to be of chemosystematic significance. The fossil samples also contained ligno-cellulose which exhibited only partial degradation, primarily of the carbohydrate constituents. Comparison between the fossil cone scale and seed pyrolysates indicated that the ligno-cellulose complex present in the seeds is chemically more resistant than that in the cone scales. Principal component analysis (PCA) of the pyrolysis data allowed for the determination of the discriminant functions used to assess the extent of degradation and the chemosystematic differences between both genera and between cone scales and seeds. Elemental composition (C, O, S), obtained using electron-microprobe, corroborated the pyrolysis results. Overall, the combination of chemical, microscopic and statistical methods allowed for a detailed characterization and chemosystematic interpretations of modern and fossil conifer cone scales and seeds.

    2003-03-01

    The optimisation of the formulation of a commercial bubble bath was performed by chemometric analysis of Panel Tests results. A first Panel Test was performed to choose the best essence, among four proposed to the consumers; the best essence chosen was used in the revised commercial bubble bath. Afterwards, the effect of changing the amount of four components (the amount of primary surfactant, the essence, the hydratant and the colouring agent) of the bubble bath was studied by a fractional factorial design. The segmentation of the bubble bath market was performed by a second Panel Test, in which the consumers were requested to evaluate the samples coming from the experimental design. The results were then treated by Principal Component Analysis. The market had two segments: people preferring a product with a rich formulation and people preferring a poor product. The final target, i.e. the optimisation of the formulation for each segment, was obtained by the calculation of regression models relating the subjective evaluations given by the Panel and the compositions of the samples. The regression models allowed to identify the best formulations for the two segments ofthe market.

    2017-10-01

    The ability of scientific simulations to effectively deliver performant computation is increasingly being challenged by successive generations of high-performance computing architectures. Code development to support efficient computation on these modern architectures is both expensive, and highly complex; if it is approached without due care, it may also not be directly transferable between subsequent hardware generations. Previous works have discussed techniques to support the process of adapting a legacy code for modern hardware generations, but despite the breakthroughs in the areas of mini-app development, portable-performance, and cache oblivious algorithms the problem still remains largely unsolved. In this work we demonstrate how a focus on platform agnostic modern code-development can be applied to Particle-in-Cell (PIC) simulations to facilitate effective scientific delivery. This work builds directly on our previous work optimizing VPIC, in which we replaced intrinsic based vectorisation with compile generated auto-vectorization to improve the performance and portability of VPIC. In this work we present the use of a specialized SIMD queue for processing some particle operations, and also preview a GPU capable OpenMP variant of VPIC. Finally we include a lessons learnt.

    2013-01-01

    This book offers a compact introduction to modern linear control design.  The simplified overview presented of linear time-domain methodology paves the road for the study of more advanced non-linear techniques. Only rudimentary knowledge of linear systems theory is assumed - no use of Laplace transforms or frequency design tools is required. Emphasis is placed on assumptions and logical implications, rather than abstract completeness; on interpretation and physical meaning, rather than theoretical formalism; on results and solutions, rather than derivation or solvability.  The topics covered include transient performance and stabilization via state or output feedback; disturbance attenuation and robust control; regional eigenvalue assignment and constraints on input or output variables; asymptotic regulation and disturbance rejection. Lyapunov theory and Linear Matrix Inequalities (LMI) are discussed as key design methods. All methods are demonstrated with MATLAB to promote practical use and comprehension. ...

    2017-10-01

    The significance of the different shapes of molybdenum disulfide nanoparticles contained in ethylene glycol has recently attracted researchers, because of the numerical or experimental analyses on the shapes of molybdenum disulfide and the lack of fractionalized analytic approaches. This work is dedicated to examining the shape impacts of molybdenum disulfide nanofluids in the mixed convection flow with magnetic field and a porous medium. Ethylene glycol is chosen as the base fluid in which molybdenum disulfide nanoparticles are suspended. Non-spherically shaped molybdenum disulfide nanoparticles, namely, platelet, blade, cylinder and brick, are utilized in this analysis. The modeling of the problem is characterized by employing the modern approach of Atangana-Baleanu fractional derivatives and the governing partial differential equations are solved via Laplace transforms with inversion. Solutions are obtained for temperature distribution and velocity field and expressed in terms of compact form of M-function, Mba(T) . In the end, a figures are drawn to compare the different non-spherically shaped molybdenum disulfide nanoparticles. Furthermore, the Atangana-Baleanu fractional derivatives model has been compared with ordinary derivatives models and discussed graphically by setting various rheological parameters.

  15. A HUMAN FACTORS META MODEL FOR U.S. NUCLEAR POWER PLANT CONTROL ROOM MODERNIZATION

    Energy Technology Data Exchange (ETDEWEB)

    Joe, Jeffrey C.

    2017-03-01

    Over the last several years, the United States (U.S.) Department of Energy (DOE) has sponsored human factors research and development (R&D) and human factors engineering (HFE) activities through its Light Water Reactor Sustainability (LWRS) program to modernize the main control rooms (MCR) of commercial nuclear power plants (NPP). Idaho National Laboratory (INL), in partnership with numerous commercial nuclear utilities, has conducted some of this R&D to enable the life extension of NPPs (i.e., provide the technical basis for the long-term reliability, productivity, safety, and security of U.S. NPPs). From these activities performed to date, a human factors meta model for U.S. NPP control room modernization can now be formulated. This paper discusses this emergent HFE meta model for NPP control room modernization, with the goal of providing an integrated high level roadmap and guidance on how to perform human factors R&D and HFE for those in the U.S. nuclear industry that are engaging in the process of upgrading their MCRs.

    2014-01-01

    Background: Palpitation is a sign of a disease and is very common in general population. For this purpose we decided to explain it in this study. Objectives: The purpose of this study was to describe the palpitation in both modern and traditional medicine aspect. It may help us to diagnose and cure better because the traditional medicine view is holistic and different from modern medicine. Materials and Methods: We addressed some descriptions to the articles of traditional medicine subjects which have published recently. Palpitation in modern medicine was extracted from medical books such as Braunwald, Harrison and Guyton physiology and some related articles obtained from authentic journals in PubMed and Ovid and Google scholar between1990 to 2013. Results: According to modern medicine, there are many causes for palpitation and in some cases it is cured symptomatically. In traditional medicine view, palpitation has been explained completely and many causes have been described. Its aspect is holistic and it cures causatively. The traditional medicine scientists evaluated the body based on Humors and temperament. Temperament can be changed to dis-temperament in diseases. Humors are divided in 4 items: sanguine, humid or phlegm, melancholy and bile. Palpitation is a disease, it is heart vibration and is caused by an abnormal substance in the heart itself or its membrane or other adjacent organs that would result in the heart suffering. Conclusions: Our data of this article suggests that causes of palpitation in the aspect of traditional medicine are completely different from modern medicine. It can help us to approach and treat this symptom better and with lower side effects than chemical drugs. According to this article we are able to detect a new approach in palpitation. PMID:24719741

    Teratology is the science of congenital developmental disorders (CDDs), overt or latent defects of the organism resulting from the effect of internal and external factors on developmental processes. In this article the significance and position of present-day teratology is discussed in the context of development of this branch of science and related disciplines. The authors present an updated overview of the most important milestones and stages of the development of teratology. Based on the analysis of the historical development of theses and theories that represent a decisive contribution to this field, we present a survey of the fundamental principles of experimental and clinical teratology. The aim of observing these principles is to get insight into developmental relations and to understand mechanisms of action on the level of cell populations (elementary morphogenetic processes), tissues and organs. It is important to realize that any negative intervention into the normal course of these processes, either on genetic or non-genetic basis, inevitably leads to a sequence of subsequent changes resulting in the development of congenital developmental disorders. Despite modern approaches of molecular biology and genetics, along with top diagnostic techniques, we are still not able to identify the actual cause in more than 50% of all congenital defects. One-half of the unidentified cases are referred to as "multifactorial", a term that is rather ambiguous. It either means that some of the basic principles of teratogenesis still escape our attention, or the interpretation of some of the well known principles might be misleading. A third possibility is rather pessimistic. The development of the individual is so sophisticated and dependent on a delicate network of a multitude of factors mutually affecting each other that it is extremely prone to give rise to a plethora of spontaneous errors which are unpredictable and impossible to prevent. Nevertheless, the long and

    Highlights: •The model is linked to known physicochemical degradation processes and material properties. •Aging dynamics of various battery formulations can be understood by the proposed model. •Large number of experiments will be reduced to accelerate the battery design process. •This approach can describe batteries under various operating conditions. •The proposed model is simple and easily implemented. -- Abstract: A five-state nonhomogeneous Markov chain model, which is an effective and promising way to accelerate the Li-ion battery design process by investigating the capacity fading dynamics of different formulations during the battery design phase, is reported. The parameters of this model are linked to known physicochemical degradation dynamics and material properties. Herein, the states and behaviors of the active materials in Li-ion batteries are modelled. To verify the efficiency of the proposed model, a dataset from approximately 3 years of cycling capacity fading experiments of various formulations using several different materials provided by Contemporary Amperex Technology Limited (CATL), as well as a NASA dataset, are employed. The capabilities of the proposed model for different amounts (50%, 70%, and 90%) of available experimental capacity data are tested and analyzed to assist with the final design determination for manufacturers. The average relative errors of life cycling prediction acquired from these tests are less than 2.4%, 0.8%, and 0.3%, even when only 50%, 70%, and 90% of the data, respectively, is available for different anode materials, electrolyte materials, and individual batteries. Furthermore, the variance is 0.518% when only 50% of the data are available; i.e., one can save at least 50% of the total experimental time and cost with an accuracy greater than 97% in the design phase, which demonstrates an effective and promising way to accelerate the Li-ion battery design process.

    This volume focuses on the outstanding contributions made by botany and the mathematical sciences to the genesis and development of early modern garden art and garden culture. The many facets of the mathematical sciences and botany point to the increasingly “scientific” approach that was being adopted in and applied to garden art and garden culture in the early modern period. This development was deeply embedded in the philosophical, religious, political, cultural and social contexts, running parallel to the beginning of processes of scientization so characteristic for modern European history. This volume strikingly shows how these various developments are intertwined in gardens for various purposes.

    Niosomes have been reported as a possible approach to improve the low skin penetration and bioavailability characteristics shown by conventional topical vehicle for minoxidil. Niosomes formed from polyoxyethylene alkyl ethers (Brij) or sorbitan monoesters (Span) with cholesterol molar ratios of 0, 1 and 1.5 were prepared with varying drug amount 20-50mg using thin film-hydration method. The prepared systems were characterized for entrapment efficiency, particle size, zeta potential and stability. Skin permeation studies were performed using static vertical diffusion Franz cells and hairless mouse skin treated with either niosomes, control minoxidil solution (propylene glycol-water-ethanol at 20:30:50, v/v/v) or a leading topical minoxidil commercial formulation (Minoxyl). The results showed that the type of surfactant, cholesterol and incorporated amount of drug altered the entrapment efficiency of niosomes. Higher entrapment efficiency was obtained with the niosomes prepared from Span 60 and cholesterol at 1:1 molar ratio using 25mg drug. Niosomal formulations have shown a fairly high retention of minoxidil inside the vesicles (80%) at refrigerated temperature up to a period of 3 months. It was observed that both dialyzed and non-dialyzed niosomal formulations (1.03+/-0.18 to 19.41+/-4.04%) enhanced the percentage of dose accumulated in the skin compared to commercial and control formulations (0.11+/-0.03 to 0.48+/-0.17%) except dialyzed Span 60 niosomes. The greatest skin accumulation was always obtained with non-dialyzed vesicular formulations. Our results suggest that these niosomal formulations could constitute a promising approach for the topical delivery of minoxidil in hair loss treatment.

  4. A signed particle formulation of non-relativistic quantum mechanics

    Energy Technology Data Exchange (ETDEWEB)

    2015-09-15

    A formulation of non-relativistic quantum mechanics in terms of Newtonian particles is presented in the shape of a set of three postulates. In this new theory, quantum systems are described by ensembles of signed particles which behave as field-less classical objects which carry a negative or positive sign and interact with an external potential by means of creation and annihilation events only. This approach is shown to be a generalization of the signed particle Wigner Monte Carlo method which reconstructs the time-dependent Wigner quasi-distribution function of a system and, therefore, the corresponding Schrödinger time-dependent wave-function. Its classical limit is discussed and a physical interpretation, based on experimental evidences coming from quantum tomography, is suggested. Moreover, in order to show the advantages brought by this novel formulation, a straightforward extension to relativistic effects is discussed. To conclude, quantum tunnelling numerical experiments are performed to show the validity of the suggested approach.

  6. Formulating informative, data-based priors for failure probability estimation in reliability analysis

    Guikema, Seth D.

    2007-01-01

    Priors play an important role in the use of Bayesian methods in risk analysis, and using all available information to formulate an informative prior can lead to more accurate posterior inferences. This paper examines the practical implications of using five different methods for formulating an informative prior for a failure probability based on past data. These methods are the method of moments, maximum likelihood (ML) estimation, maximum entropy estimation, starting from a non-informative 'pre-prior', and fitting a prior based on confidence/credible interval matching. The priors resulting from the use of these different methods are compared qualitatively, and the posteriors are compared quantitatively based on a number of different scenarios of observed data used to update the priors. The results show that the amount of information assumed in the prior makes a critical difference in the accuracy of the posterior inferences. For situations in which the data used to formulate the informative prior is an accurate reflection of the data that is later observed, the ML approach yields the minimum variance posterior. However, the maximum entropy approach is more robust to differences between the data used to formulate the prior and the observed data because it maximizes the uncertainty in the prior subject to the constraints imposed by the past data

    1992-01-01

    A procedure for auditing radiopharmaceutical formulations is described. To meet FDA guidelines regarding the quality of radiopharmaceuticals, institutional radioactive drug research committees perform audits when such drugs are formulated away from an institutional pharmacy. All principal investigators who formulate drugs outside institutional pharmacies must pass these audits before they can obtain a radiopharmaceutical investigation permit. The audit team meets with the individual who performs the formulation at the site of drug preparation to verify that drug formulations meet identity, strength, quality, and purity standards; are uniform and reproducible; and are sterile and pyrogen free. This team must contain an expert knowledgeable in the preparation of radioactive drugs; a radiopharmacist is the most qualified person for this role. Problems that have been identified by audits include lack of sterility and apyrogenicity testing, formulations that are open to the laboratory environment, failure to use pharmaceutical-grade chemicals, inadequate quality control methods or records, inadequate training of the person preparing the drug, and improper unit dose preparation. Investigational radiopharmaceutical formulations, including nonradiolabeled drugs, must be audited before they are administered to humans. A properly trained pharmacist should be a member of the audit team

  13. Canonical formulation of general-relativistic theories

    International Nuclear Information System (INIS)

    Bergmann, P.G.

    1987-01-01

    With the birth of quantum field theory in the late twenties physicists decided that nature could not be half classical and half quantum, and that the gravitational field ought to be quanticized, just as the electromagnetic field had been. One could accept the group of differomorphisms as a fundamental characteristic of general relativity (and indeed of all general-relativistic theories), and proceed to construct a quantum field-theory that was adapted to that group. Quantization would be attempted by way of a Hamiltonian formulation of the (classical) theory, and quantum commutation relations be patterned after the Poisson brackets arising in that formulation. This program is usually called the canonical quantization program, whereas the weak-field approach is known as covariant quantization. The first steps, conceived entirely within the framework of the classical theory, turned out to be beset with technical and conceptual difficulties, which today are essentially resolved. In this paper the author traces out these initial steps

    2014-10-01

    An analysis and some generalizations of approaches to risk assessments are presented. Interconnection between different interpretations of the "risk" notion is shown, and the possibility of applying the fuzzy set theory to risk assessments is demonstrated. A generalized formulation of the risk assessment notion is proposed in applying risk-oriented approaches to the problem of enhancing reliability and safety in nuclear power engineering. The solution of problems using the developed risk-oriented approaches aimed at achieving more reliable and safe operation of NPPs is described. The results of studies aimed at determining the need (advisability) to modernize/replace NPP elements and systems are presented together with the results obtained from elaborating the methodical principles of introducing the repair concept based on the equipment technical state. The possibility of reducing the scope of tests and altering the NPP systems maintenance strategy is substantiated using the risk-oriented approach. A probabilistic model for estimating the validity of boric acid concentration measurements is developed.

The author concludes that the various components of the religious consciousness of the Japanese were kontratetycal on two main elements that form the basis of modern Western culture Japanese resistance and cause upgrade. First, science and technology, working on the basis of the laws of nature, which are opposed to the supernatural and the metaphysical world. Secondly, expressed individualism and atomism as hypertrophic respect for the human person, liberal nadzoseredzhenist to a person who undermines the consolidation of corporate social society. Japanese culture in the past was oriented toward modernization, but progress has been very slow. Moreover, in this process, Japan was much more conservative because in Japanese society regulatory institutions of the army, religion and industrial corporations can be considered a kind of constants which not only can be adapted to the modernization of Euro-American style, as suggested selection of authentic script compatible, especially with life values corporatism and solidarity. It is in this dimension of modernization projects related to Christian proselytism, as were «frustrated.» The reason for this breakdown can be considered inherence religion with social cohesion, its actual merging of social institutions, as well as hidden mahizm skepticism and religious outlook that combines Shinto, Confucian and Zen Buddhist elements. Since modernization in Christianity included the distinction darkened minds clerical era and «enlightened enlightenment» of consciousness era of modern times, it is this dichotomy allowed to oppose religious «ignorance» and scientific «enlightenment», the clergy and secular intellectuals, universities and intellectual clubs as a medium spreading the ideology of the bourgeoisie and monasteries as centers of religious clericalism

  17. A fully implicit Newton-Krylov-Schwarz method for tokamak magnetohydrodynamics: Jacobian construction and preconditioner formulation

    Reynolds, Daniel R.

    2012-01-01

    Single-fluid resistive magnetohydrodynamics (MHD) is a fluid description of fusion plasmas which is often used to investigate macroscopic instabilities in tokamaks. In MHD modeling of tokamaks, it is often desirable to compute MHD phenomena to resistive time scales or a combination of resistive-Alfvén time scales, which can render explicit time stepping schemes computationally expensive. We present recent advancements in the development of preconditioners for fully nonlinearly implicit simulations of single-fluid resistive tokamak MHD. Our work focuses on simulations using a structured mesh mapped into a toroidal geometry with a shaped poloidal cross-section, and a finite-volume spatial discretization of the partial differential equation model. We discretize the temporal dimension using a fully implicit or the backwards differentiation formula method, and solve the resulting nonlinear algebraic system using a standard inexact Newton-Krylov approach, provided by the sundials library. The focus of this paper is on the construction and performance of various preconditioning approaches for accelerating the convergence of the iterative solver algorithms. Effective preconditioners require information about the Jacobian entries; however, analytical formulae for these Jacobian entries may be prohibitive to derive/implement without error. We therefore compute these entries using automatic differentiation with OpenAD. We then investigate a variety of preconditioning formulations inspired by standard solution approaches in modern MHD codes, in order to investigate their utility in a preconditioning context. We first describe the code modifications necessary for the use of the OpenAD tool and sundials solver library. We conclude with numerical results for each of our preconditioning approaches in the context of pellet-injection fueling of tokamak plasmas. Of these, our optimal approach results in a speedup of a factor of 3 compared with non-preconditioned implicit tests, with

    Currently, people are more interested to traditional medicine. The traditional formulations should be converted to modern drug delivery systems to be more acceptable for the patients. In the present investigation, a poly herbal medicine "Ayarij-e-Faiqra" (AF) based on Iranian traditional medicine (ITM) has been formulated and its quality control parameters have been developed. The main ingredients of AF including barks of Cinnamomum zeylanicum Blume and Cinnamomum cassia J. Presl, the rhizomes of Nardostachys jatamansi DC., the fruits of Piper cubeba L.f., the flowers of Rosa damascena Herrm., the oleo gum resin of Pistacia terebinthus L. and Aloe spp. dried juice were powdered and used for preparing seven tablet formulations of the herbal mixture. Flowability of the different formulated powders was examined and the best formulations were selected (F6&F7). The tablets were prepared from the selected formulations compared according to the physical characteristics and finally, F7 was selected and coated. Physicochemical characters of core and coated AF tablets were determined and the HPLC method for quantitation of aloin as a marker of tablets was selected and verified according to selectivity, linearity, precision, recovery, LOD and LOQ. The results showed that core and coated AF tablets were in agreement with USP requirements for herbal drugs. They had acceptable appearance, disintegration time, friability, hardness, dissolution behavior, weight variation and content uniformity. The amount of aloin in tablets was found 123.1 mg/tab. The HPLC method for aloin determination in AF tablets was verified according to selectivity, linearity (5-500 μg/ml, r 2 :0.9999), precision (RSD: 1.62%), recovery (108.0%), LOD & LOQ (0.0053 & 0.0161 μg/ml). The formulated tablets could be a good substitute for powder and capsules of AF in ITM clinics with a feasible and precise method for its quality control. Ayarij-e-Faiqra formulation.

I critically readdress the idea, found in his early work, that modernity is characterized by a rupture with pre-modern forms of solidarity. First, I investigate...... the ways in which Durkheim sets up a stark distinction between the pre-modern and the modern in his early work, and how this distinction is further cemented by his orthodox critique of the modern economy and its negative effects on social life. Second, I show how another timeless and positive understanding...... of “mechanical” solidarity is to be found behind the “symbolist” template crystalizing in Durkheim’s late work. Third, I develop this template for a modern context by critically addressing and removing other obstacles and prejudices on Durkheim’s part....

    It has been proposed that the best storage environment for materials in museum collections is between +10 and -20°C. The basis for this assertion is that a 10°C reduction in temperature halves the rate of chemical reactions, and many modern materials are short-lived. In practice, few museums apply...... cold storage to their collections, with the exception of photographic archives, so there is limited experience of its effectiveness in preservation. Plastics are formulated by combining polymers, property modifiers, and colors. Each material has its own thermal response. On cooling, polymer...... crystallinity increases, resulting in a reduced compatibility of low molecular weight components. This article discusses the influence of reducing the storage temperature on the physical properties of plastics, based on both theory and experimental findings.

    Against a backdrop of global antibiotic resistance and increasing awareness of the importance of the human microbiota, there has been resurgent interest in the potential use of bacteriophages for therapeutic purposes, known as phage therapy. A number of phage therapy phase I and II clinical trials have concluded, and shown phages don't present significant adverse safety concerns. These clinical trials used simple phage suspensions without any formulation and phage stability was of secondary concern. Phages have a limited stability in solution, and undergo a significant drop in phage titre during processing and storage which is unacceptable if phages are to become regulated pharmaceuticals, where stable dosage and well defined pharmacokinetics and pharmacodynamics are de rigueur. Animal studies have shown that the efficacy of phage therapy outcomes depend on the phage concentration (i.e. the dose) delivered at the site of infection, and their ability to target and kill bacteria, arresting bacterial growth and clearing the infection. In addition, in vitro and animal studies have shown the importance of using phage cocktails rather than single phage preparations to achieve better therapy outcomes. The in vivo reduction of phage concentration due to interactions with host antibodies or other clearance mechanisms may necessitate repeated dosing of phages, or sustained release approaches. Modelling of phage-bacterium population dynamics reinforces these points. Surprisingly little attention has been devoted to the effect of formulation on phage therapy outcomes, given the need for phage cocktails, where each phage within a cocktail may require significantly different formulation to retain a high enough infective dose. This review firstly looks at the clinical needs and challenges (informed through a review of key animal studies evaluating phage therapy) associated with treatment of acute and chronic infections and the drivers for phage encapsulation.

Focusing on the contemporary Moral Sense philosophical ideas formulated primarily by leading members of the Kirk, and the medical writings of the Scottish physicians, George Cheyne, John Gregory, and William Cullen, this chapter explores the fusion of classical and holistic Christian-based medical ethics. It is argued that it was the convergence of new theories of nervous sensibility, Scottish Enlightenment, Christian-based sentimental moral philosophies, and the rhetoric of the "man of feeling" that created a new modern medical ethics.

    Assessment of skin sensitization potential is an important component of the safety evaluation process for agrochemical products. Recently, non-animal approaches including the KeratinoSens™ assay have been developed for predicting skin sensitization potential. Assessing the utility of the KeratinoSens™ assay for use with multi-component mixtures such as agrochemical formulations has not been previously evaluated and is a significant need. This study was undertaken to evaluate the KeratinoSens™ assay prediction potential for agrochemical formulations. The assay was conducted for 8 agrochemical active ingredients (AIs) including 3 sensitizers (acetochlor, meptyldinocap, triclopyr), 5 non-sensitizers (aminopyralid, clopyralid, florasulam, methoxyfenozide, oxyfluorfen) and 10 formulations for which in vivo sensitization data were available. The KeratinoSens™ correctly predicted the sensitization potential of all the AIs. For agrochemical formulations it was necessary to modify the standard assay procedure whereby the formulation was assumed to have a common molecular weight. The resultant approach correctly predicted the sensitization potential for 3 of 4 sensitizing formulations and all 6 non-sensitizing formulations when compared to in vivo data. Only the meptyldinocap-containing formulation was misclassified, as a result of high cytotoxicity. These results demonstrate the promising utility of the KeratinoSens™ assay for evaluating the skin sensitization potential of agrochemical AIs and formulations. Copyright © 2015 Elsevier Inc.

    We wanted to compare the dissolution profile of several over-the-counter analgesics to understand whether the different formulation techniques employed to enhance absorption were associated with variations in the dissolution rate, a parameter known to affect drug absorption. We considered 5 formulations currently marketed in Italy: aspirin tablets (Aspirina Dolore e Infiammazione®), ibuprofen tablets and liquid capsules (Moment®), ibuprofen lysine tablets (Nurofenimmedia®) and dexketoprofen trometamol tablets (Enantyum®). Dissolution tests were performed according to the current USP/NF monograph dissolution procedure. Drug dissolution was evaluated at 1, 3, 6, 15, and 30 minutes since the start of the test. Dissolution was evaluated at three different pH: 1.2, 4.5 and 6.8. Every test was repeated 12 times. The aspirin formulation was by far the most rapid dissolving formulation, among those tested, with more than 80% of the tablet dissolved at 6 minutes for every pH considered. At pH 1.2 and 4.5, only the dexketoprofen formulation was able to reach the dissolution level of aspirin at 30 minutes, but had lower levels of dissolution at the previous time points. Instead, at pH 6.8, most of the formulations approached aspirin dissolution level, but only after 15 minutes. Ibuprofen capsules had the slowest kinetics, with a lag phase the first 6 minutes. Different formulation strategies can lead to great differences in the dissolution rates even among drugs of the same class, suggesting that enhancements in the formulation of painkillers can lead to improvements in drug absorption, and thus in the onset of analgesia.

    Full Text Available Ayurveda represents the traditional medicine system of India. Since mechanistic details of therapy in terms of current biology are not available in Ayurvedic literature, modern scientific studies are necessary to understand its major concepts and procedures. It is necessary to examine effects of the whole Ayurvedic formulations rather than their "active" components as is done in most current studies.We tested two different categories of formulations, a Rasayana (Amalaki Rasayana or AR, an herbal derivative and a Bhasma (Rasa-Sindoor or RS, an organo-metallic derivative of mercury, for effects on longevity, development, fecundity, stress-tolerance, and heterogeneous nuclear ribonucleoprotein (hnRNP levels of Drosophila melanogaster using at least 200 larvae or flies for each assay.A 0.5% (weight/volume supplement of AR or RS affected life-history and other physiological traits in distinct ways. While the size of salivary glands, hnRNP levels in larval tissues, and thermotolerance of larvae/adult flies improved significantly following feeding either of the two formulations, the median life span and starvation resistance improved only with AR. Feeding on AR or RS supplemented food improved fecundity differently. Feeding of larvae and adults with AR increased the fecundity while the same with RS had opposite effect. On the contrary, feeding larvae on normal food and adults on AR supplement had no effect on fecundity but a comparable regime of feeding on RS-supplemented food improved fecundity. RS feeding did not cause heavy metal toxicity.The present study with two Ayurvedic formulations reveals formulation-specific effects on several parameters of the fly's life, which seem to generally agree with their recommended human usages in Ayurvedic practices. Thus, Drosophila, with its very rich genetic tools and well-worked-out developmental pathways promises to be a very good model for examining the cellular and molecular bases of the effects of

    Full Text Available The purpose of this study is to show why the modern business institution (company should be Islamized, and to suggest ways in which shari’ah principles can be applied in the company. To achieve this purpose, we should understand how company be islamized in comprehensive and integrated  manner through the Islamic law perspective, with the contemporary issues like underlying contract of company,  legal entity, and the concept of liability. The resolution of these issues is important to assert that shari’ah principles could be applied in the modern company by integrating approach. An integrating approach in the treating of these issues has, however, been lacking, nor has it been subjected to a thorough legal analysis through the principles of Islamic business law.   Tujuan dari pembahasan ini adalah untuk menunjukkan bahwa institusi bisnis modern (perusahaan harus diislamisasi, dan member masukan cara-cara bagimana prinsip- prinsip shari’ah dapat ditetapkan dalam perusahaan. Untuk mencapai tujuan ini, kita perlu memahami bagaimana perusahaan diislamisasi secara menyeluruh dan terintegrasi melalui perspektif hukum Islam terhadap persoalan kontemporer, seperti landasan kontrak perusahaan, badan hukum, dan konsep liabilitas. Solusi dari persoalan ini sangat penting untuk   menegaskan bahwa prinsip-prinsip shari’ah dapat ditetapkan pada perusahaan modern melalui pendekatan integrasi. Bagaimanapun, pendekatan integrasi dalam menyikapi persoalan ini jarang dilakukan, disamping tidak menjadi tema analisis melalui prinsip-prinsip hukum bisnis Islami.

    Full Text Available Background and objectives: Melasma is one of the most common pigmentary disorders. It has a considerable impact on quality of life. The treatment of melasma has still remained a challenge because the efficient treatment has not been proven until now and there is still a need to find new depigmenting products.Allium cepa L. and Cucumis melo L. seeds as well as tragacanth have been introduced in Iranian traditional medicine (ITM as depigmenting agents. Moreover, modern studies have shown their antioxidant and inhibitory mushroom tyrosinase effect.In this study, a topical gel containing Allium cepa L. and Cucumis melo L. seeds extract was prepared with tragacanth and quality control evaluations have been accomplished. Method: After performing quality control of plants seeds and tragacanth according to pharmacopoeia, the ethanol extract of A. cepa and hydroalcoholic extract of C. melo seeds were prepared. An appropriate gel formulation was selected on the base of suitable viscosity. The gel product was formulated using 5% of each plant extracts in tragacanth gel base. In addition, the herbal gel was evaluated using pharmaceutical behavior such as physical appearance, pH, viscosity, spreadability as well as phenolics content. Results: The herbal gel product showed acceptable pharmaceutical behavior as well as considerable phenolic content (1.43±0.01 mg/g. Conclusion: The prepared topical gel product could be a good natural formulation candidate for clinical studies in the field of hyperpigmentation. Moreover, phenolic content of the product could be considered as an indicator for its quality control.

    2011-01-01

    Full Text Available The paper explores the introduction and articulation of ideas and aesthetic practice of postmodernism in architecture of late socialism in Yugoslavia, with the focus on Belgrade architecture scene. Theoretical and methodological point of departure of this analysis is Jürgen Habermas's thesis of modernity as an incomplete, i.e., unfinished project, from his influential essay “Die Moderne: Ein unvollendetes Projekt” (1980. The thematic framework of the paper is shifted towards issues raised by Habermas which concern relations of cultural modernity and societal modernization, or rather towards consideration of architectural postmodernity in relation to the split between culture and society. The paper investigates architectural discourse which was profiled in Belgrade in 1980s, in a historical context of cultural modernity simultaneous with Habermas's text, but in different conditions of societal modernization of Yugoslav late socialism. In that, the principle methodological question concerns the interpretation of postmodern architecture as part of the new cultural production within the social restructuration of late and/or end of socialism as a system, that being analogous to Fredric Jameson's thesis of “Postmodernism, Or, The Cultural Logic of Late Capitalism” (1984.

    2014-01-01

    In the last decades several new biotechnologically-based therapeutics have been developed due to progress in genetic engineering. A growing challenge facing pharmaceutical scientists is formulating these compounds into oral dosage forms with adequate bioavailability. An increasingly popular approach to formulate biotechnology-based therapeutics is the use of lipid based formulation technologies. This review highlights the importance of lipid based drug delivery systems in the formulation of oral biotechnology based therapeutics including peptides, proteins, DNA, siRNA and vaccines. The different production procedures used to achieve high encapsulation efficiencies of the bioactives are discussed, as well as the factors influencing the choice of excipient. Lipid based colloidal drug delivery systems including liposomes and solid lipid nanoparticles are reviewed with a focus on recent advances and updates. We further describe microemulsions and self-emulsifying drug delivery systems and recent findings on bioactive delivery. We conclude the review with a few examples on novel lipid based formulation technologies.

Se sostiene que este deporte permite reflexionar en torno a un conjunto de valores y características de nuestras sociedades actuales. La moda, la tecnología, la diversidad sexual y étnica, el espectáculo, la publicidad, la aceleración, el erotismo, el éxito y el fracaso o el capitalismo globalizado aparecen como componentes imprescindibles para poder captar el fenómeno tenístico en toda su amplitud. Igualmente, la historia del tenis puede servir para ilustrar como a través del deporte se puede comprender la evolución socio-cultural de la civilización occidental. --------------------------------------------In this paper, the authors investigate an approach to the practice of tennis as a metaphor of modernity and post-modernity (also called hypermodernity. It is a wellknown fact that the origins of tennis go back to pre-modern times, when it was known as jeu de paume and widely practiced during the Ancient Regime. The autors, argue that this sport enables reflection on a series of values and features of modern society. Fashion, technology, sexual and ethnic diversity, spectacle, advertising, acceleration, eroticism, success and failure or globalised capitalism emerge as indispensable elements for understanding the tennis phenomenon in all its breadth. Likewise, the history of tennis may also illustrate how the sociocultural evolution of Western civilisation can be understood through spor.

    In high power, high voltage electronics systems, a strategy to manage short timescale energy imbalances is fundamental to the system reliability. Without a theoretical framework, harmful local convergence of energy can affect the dynamic process of transformation, transmission, and storage which create an unreliable system. With an original approach that encourages understanding of both macroscopic and microscopic factors, the authors offer a solution. They demonstrate the essential theory and methodology for the design, modeling and prototyping of modern power electronics converters to crea

    Aerosolized administration of biopharmaceuticals to the airways is a promising route for nasal and pulmonary drug delivery, but - in contrast to small molecules - little is known about the effects of aerosolization on safety and efficacy of biopharmaceuticals. Proteins are sensitive against aerosolization-associated shear stress. Tailored formulations can shield proteins and enhance permeation, but formulation development requires extensive screening approaches. Thus, the aim of this study was to develop a cell-based in vitro technology platform that includes screening of protein quality after aerosolization and transepithelial permeation. For efficient screening, a previously published aerosolization-surrogate assay was used in a design of experiments approach to screen suitable formulations for an IgG and its antigen-binding fragment (Fab) as exemplary biopharmaceuticals. Efficient, dose-controlled aerosol-cell delivery was performed with the ALICE-CLOUD system containing RPMI 2650 epithelial cells at the air-liquid interface. We could demonstrate that our technology platform allows for rapid and efficient screening of formulations consisting of different excipients (here: arginine, cyclodextrin, polysorbate, sorbitol, and trehalose) to minimize aerosolization-induced protein aggregation and maximize permeation through an in vitro epithelial cell barrier. Formulations reduced aggregation of native Fab and IgG relative to vehicle up to 50% and enhanced transepithelial permeation rate up to 2.8-fold. Copyright © 2017 The Author(s).

    2017-01-01

    Modern service company (MSC), the enterprise involving special domains, such as the financial industry, information service industry and technology development industry, depends heavily on information technology. Modelling of such enterprise has attracted much research attention because it promises to help enterprise managers to analyse basic business strategies (e.g. the pricing strategy) and even optimise the business process (BP) to gain benefits. While the existing models proposed by economists cover the economic elements, they fail to address the basic BP and its relationship with the economic characteristics. Those proposed in computer science regardless of achieving great success in BP modelling perform poorly in supporting the economic analysis. Therefore, the existing approaches fail to satisfy the requirement of enterprise modelling for MSC, which demands simultaneous consideration of both economic analysing and business processing. In this article, we provide a unified enterprise modelling approach named Enterprise Pattern (EP) which bridges the gap between the BP model and the enterprise economic model of MSC. Proposing a language named Enterprise Pattern Description Language (EPDL) covering all the basic language elements of EP, we formulate the language syntaxes and two basic extraction rules assisting economic analysis. Furthermore, we extend Business Process Model and Notation (BPMN) to support EPDL, named BPMN for Enterprise Pattern (BPMN4EP). The example of mobile application platform is studied in detail for a better understanding of EPDL.

    2014-01-01

    Full Text Available A large number of authors examine the problem of environmental protection in their papers. The concept of sustainable development and intensive use of modern technology in order to overcome the environmental problems of modern civilization becomes an imperative. Theoretical engagement in ecological issues is not enough. It is necessary to implement ecological measures in practice and to spread environmental awareness. Modern science and social practice have interdependence of economy and ecology in their focus. The main direction of social change is movement from economic to ecological paradigm that involves an ethical responsibility to the current and future generations. There is a need to establish effective programs to protect the environment at the national and supranational level. Active international cooperation in the field of ecology has resulted in the formulation of a number of documents on environmental protection. This paper illustrates the importance of environmental protection and the necessity of implementing international conventions and agreements in the environmental field, with focus on their impact on international trade.

    Rosenau, P V

    1994-01-01

    In this article, post-modern theory is described and applied to health politics with examples from community health organizing, social movements, and health promotion. Post-modernism questions conventional assumptions about concepts such as representation, participation, empowerment, community, identity, causality, accountability, responsibility, authority, and roles in community health promotion (those of expert, leader, and organizer). I compare post-modern social movements with their modern counterparts: the organizational forms, leadership styles, and substantive intellectual orientations of the two differ. I explain the social planning, community development, and social action models of community health organizing, comparing them with the priorities of post-modern social movements, and show the similarities and differences between them as to structural preferences, process, and strategies. Finally, and most importantly, I present the implicit lessons that post-modernism offers to health politics and outline the strengths and weaknesses of this approach to health politics.

    Application of modern scientific knowledge coupled with sensitive analytical technique is important for the quality evaluation and standardization of polyherbal formulations. Semecarpus anacardium, an important medicinal plant with wide medicinal properties, is frequently used in a large number of traditional herbal preparations. Tetrahydroamentoflavone (THA), a major bioactive biflavonoid was selected as a chemical marker of S. anacardium and RP-semi-preparative HPLC conditions were optimized for the isolation of tetrahydroamentoflavone. HPTLC analytical method was developed for the fingerprinting of S. anacardium flavonoids and quantification of tetrahydroamentoflavone. The method was validated in terms of their linearity, LOD, LOQ, precision and accuracy and compared with RP-HPLC-DAD method. The methods were demonstrated for the chemical fingerprinting of S. anacardium plant parts and some commercial polyherbal formulations and the amount of tetrahydroamentoflavone was quantified. HPTLC analysis showed that S. anacardium seed contained approximately 10 g kg(-1) of tetrahydroamentoflavone. The methods were able to identify and quantify tetrahydroamentoflavone from complex mixtures of phytochemicals and could be extended to the marker-based standardization of polyherbal formulations, containing S. anacardium.

    The world energy consumption has been increasing strongly in recent years. Nuclear energy has been regarded as a suitable option to supply this growing energy demand in industrial scale. In view of the need of improving the understanding and capacity of analysis of nuclear power plants, modern simulation techniques for flow and heat transfer problems are gaining greater importance. A large number of problems found in nuclear reactor engineering can be dealt assuming axial symmetry. Thus, in this work a stabilized finite element formulation for the solution of the Navier-Stokes and energy equations for axisymmetric problems have been developed and tested. The formulation has been implemented in the NS S OLVER M PI 2 D A program developed at the Parallel Computation Laboratory of the Instituto de Engenharia Nuclear (LCP/IEN) and is now available either for safety analysis or design of nuclear systems.

    2014-09-01

    Full Text Available Communicating parties inside computer networks use different kind of identifiers. Some of these identifiers are stable, e.g., logins used to access a specific service, some are only temporary, e.g., dynamically assigned IP addresses. This paper tackles several challenges of lawful interception that emerged in modern networks. The main contribution is the graph model that links identities learnt from various sources distributed in a network. The inferred identities result into an interception of more detailed data in conformance with the issued court order. The approach deals with network address translation, short-lived identifiers and simultaneous usage of different identities. The approach was evaluated to be viable during real network testing based on various means to learn identities of users connected to a network.

    Full Text Available Modern taxonomy has two approaches, i.e. classical and experimental taxonomy. Classical taxonomy uses morphological characters, while experimental taxonomy uses broader methods including chemistry, physics and mathematics, in the form of laboratory data that are revealed together with the progress of optical technique (microscope, chemistry methods (chromatography, electrophoresis, etc. Modern taxonomy tends to use series of interrelated data. More data used would result in more validity and give better clarification of taxonomic status. A lot of modern taxonomic data such as palynology, cytotaxonomy (cytology, chemical constituent (chemotaxonomy, isozyme and DNA sequencing were used recently.

    2008-07-01

    In the 1960s, the Royal Government of Bhutan began developing its modern educational system. Over time, a strategic plan was formulated to meet Education for All and Millennium Development Goals. In 2003, the Royal University of Bhutan, the country's first university, opened its doors. This paper uses comparative analysis to describe and explore the impact on the development of The Royal University of Bhutan of the national consciousness termed ‹Gross National Happiness'. It is proposed that the university is likely to become a catalyst for development, and an influential representative of and for a cultural identity. Will it become an elite institution? Will the institution offer formal degrees for all who qualify? It is suggested that the issues considered in Bhutan may be of significance for other new universities attempting to establish themselves in the developing world.

    A new approach to the formulation of resveratrol (RSV) entrapped niosomes for topical use is proposed in this work. Niosomes were formulated with Gelot 64 (G64) as surfactant, and two skin-compatible unsaturated fatty acids (oleic and linoleic acids), commonly used in pharmaceutical formulations, as penetration enhancers. Niosomes were prepared by two different methods: a thin film hydration method with minor modifications followed by a sonication stage (TFH-S), and an ethanol injection modified method (EIM). Niosomes prepared with the EIM method were in the range of 299-402 nm, while the TFH-S method produced larger niosomes in the range of 293-496 nm. Moreover, niosomes with higher RSV entrapment efficiency (EE) and better stability were generated by the EIM method. Ex vivo transdermal experiments, carried out in Franz diffusion cells on newborn pig skin, indicated that niosomes prepared by the EIM method were more effective for RSV penetration in epidermis and dermis (EDD), with values up to 21% for both penetration enhancers tested. The EIM method, which yielded the best RSV-entrapped niosomes, seems to be the most suitable for scaling up. Copyright © 2015 Elsevier B.V. All rights reserved.

    A nodal formulation of a fixed-source two-dimensional neutron transport problem, in Cartesian geometry, defined in a heterogeneous medium, is solved by an analytical approach. Explicit expressions, in terms of the spatial variables, are derived for averaged fluxes in each region in which the domain is subdivided. The procedure is an extension of an analytical discrete ordinates method, the ADO method, for the solution of the two-dimensional homogeneous medium case. The scheme is developed from the discrete ordinates version of the two-dimensional transport equation along with the level symmetric quadrature scheme. As usual for nodal schemes, relations between the averaged fluxes and the unknown angular fluxes at the contours are introduced as auxiliary equations. Numerical results are in agreement with results available in the literature.

  2. Institutional statism: an overview of the formulation of the taxi recapitalisation policy

    2008-07-01

    Full Text Available This article provides an overview of the government’s formulation of the taxi recapitalisation policy which is aimed at regulating the minibus taxi industry. Coupled with a brief social and politico-historical context of the policy, the aim is to highlight the government’s statist conduct in the formulation of the recapitalisation policy. The minibus taxi industry started to fulfil a prominent role in the 1970s as a result of a loophole in the legislation of the former apartheid government. It is currently the most accessible mode of public transport and conveys 65 per cent of the country’s commuters daily. Consequently, the Industry is an imperative force to be considered by the government in its formulation of transport policies. However, the industry is characterised by numerous problems, including a high rate of minibus taxis involved in accidents, unroadworthy vehicles and violence. It is in this context that the government formulated both the original and revised versions of the recapitalisation policy. However, the formulation of the policy has been problematic. The government followed a statist approach during the formulation process when it directed the course of the process according to its interests and without adequate consultation with relevant role players.

  3. Applications of an alternative formulation for one-layer real time optimization

    2000-01-01

    Full Text Available This paper presents two applications of an alternative formulation for one-layer real time structure for control and optimization. This new formulation have arisen from predictive controller QDMC (Quadratic Dynamic Matrix Control, a type of predictive control (Model Predictive Control - MPC. At each sampling time, the values of the outputs of process are fed into the optimization-control structure which supplies the new values of the manipulated variables already considering the best conditions of process. The variables of optimization are both set-point changes and control actions. The future stationary outputs and the future stationary control actions have both a different formulation of conventional one-layer structure and they are calculated from the inverse gain matrix of the process. This alternative formulation generates a convex problem, which can be solved by less sophisticated optimization algorithms. Linear and nonlinear economic objective functions were considered. The proposed approach was applied to two linear models, one SISO (single-input/single output and the other MIMO (multiple-input/multiple-output. The results showed an excellent performance.

    Full Text Available In the article one of the modern approaches to the social structure of the society is considered. The creative class is determined as the main driving force and as a leading social class of modern society. The author studies the history of the concept of creative class, and R. Florida’s concept in particular, and determines its characteristics and peculiarities. The influence of the creative class on the society, on its transformation processes, and the system of social values is analyzed. The role of creative class in developing creative and innovative economy of the post­industrial society era is found out. The author considers the relationship between the creative class and the other social classes of modern society. The essence of the concept of creativity is defined, and one of the most important problems of the modern era that is a constant conflict between creativity and organization is examined. The comparative historical analysis of the so­called «institutional»/ «industrial» and «creative»/ «post­industrial» era is made. The role of the creative class in developing and social changing the modern American society is studied. The questions of forming and developing creative class in modern Ukrainian society are analyzed, and the peculiarities and problems of this process are figured out. The need of state support for forming national creative class, for its strengthening and growth is emphasized.

  6. Quantum gravitation. The Feynman path integral approach

    International Nuclear Information System (INIS)

    Hamber, Herbert W.

    2009-01-01

    The book covers the theory of Quantum Gravitation from the point of view of Feynman path integrals. These provide a manifestly covariant approach in which fundamental quantum aspects of the theory such as radiative corrections and the renormalization group can be systematically and consistently addressed. The path integral method is suitable for both perturbative as well as non-perturbative studies, and is known to already provide a framework of choice for the theoretical investigation of non-abelian gauge theories, the basis for three of the four known fundamental forces in nature. The book thus provides a coherent outline of the present status of the theory gravity based on Feynman's formulation, with an emphasis on quantitative results. Topics are organized in such a way that the correspondence to similar methods and results in modern gauge theories becomes apparent. Covariant perturbation theory are developed using the full machinery of Feynman rules, gauge fixing, background methods and ghosts. The renormalization group for gravity and the existence of non-trivial ultraviolet fixed points are investigated, stressing a close correspondence with well understood statistical field theory models. Later the lattice formulation of gravity is presented as an essential tool towards an understanding of key features of the non-perturbative vacuum. The book ends with a discussion of contemporary issues in quantum cosmology such as scale dependent gravitational constants and quantum effects in the early universe. (orig.)

    Due to the severe cardiotoxicity of doxorubicin, its usage is limited. This shortcoming could be overcome by modifying pharmacokinetics of the drugs via preparation of various nanoplatforms. Doxil, a well-known FDA-approved nanoplatform of doxorubicin as antineoplastic agent, is frequently used in clinics in order to reduce cardiotoxicity of doxorubicin. Since Doxil shows some shortcomings in clinics including hand and food syndrome and very slow release pattern thus, there is a demand for the development and preparation of new doxorubicin nanoformulation with fewer side effects. The new formulation of the doxorubicin, synthesized previously by our group was extensively examined in the current study. This new formulation is doxorubicin encapsulated in PEG-PLGA polymersomes (PolyDOX). The main aim of the study was to compare the distribution and treatment efficacy of a new doxorubicin-polymersomal formulation (PolyDOX) with regular liposomal formulation (Doxil-mimic) in murine colon adenocarcinoma model. Additionally, the pathological, hematological changes, pharmacodynamics, biodistribution, tolerated dose and survival rate in vivo were evaluated and compared. Murine colon cancer model was induced by subcutaneous inoculation of BALB/c mice with C26 cells. Afterwards, either Doxil-mimic or PolyDOX was administered intravenously. The obtained results from biodistribution study showed a remarkable difference in the distribution of drugs in murine organs. In this regard, Doxil-mimic exhibited prolonged (48h) presence within liver tissues while PolyDOX preferentially accumulate in tumor and the presence in liver 48h post-treatment was significantly lower than that of Doxil-mimic. Obtained results demonstrated comparable final length of life for mice receiving either Doxil-mimic or PolyDOX formulations whereas tolerated dose of mice receiving Doxil-mimic was remarkably higher than those receiving PolyDOX.

    Full Text Available Development of self-dispersing drug delivery systems (SMEDDS is a modern strategy for oral delivery improvement of poorly soluble drugs. Self-microemulsifying drug delivery systems (SMEDDS are isotropic mixtures of oils and hydrophilic surfactants, which form oil-in-water (o/w microemulsions by dilution in aqueous media (e.g., gastrointestinal fluids. Formulation of SMEDDS carriers requires consideration of a large number of formulation parameters and their influences on process of self-microemulsifying and releasing of drug. The aim of this work was formulation and characterisation of SMEDDS for oral administration of ibuprofen. In the experimental work, two series of potential SMEDDS were prepared (M1-M10, using surfactant (Labrasol®, Gattefosse, cosurfactant (PEG-40 hydrogenated castor (Cremophor® RH40, and oil (medium chain triglycerides (Crodamol® GTCC and olive oil (Cropur® Olive, at surfactant-to-cosurfactant mass ratios (Km 9:1, 7:3, 5:5, 3:7, and 1:9, and 10 % or 20 % of the oil phase. Ibuprofen was dissolved in formulations in concentration of 10 %. Characterisation of the investigated formulations included evaluation of physical stability, self-microemulsification ability in 0,1M HCl (pH 1.2 and phosphate buffer pH 7.2 (USP and in vitro drug release. Formation of o/w microemulsions with the average droplet size (Z-ave up to 100 nm, was observed in dispersions of formulations prepared with 10% w/w of medium chain triglycerides, within the entire investigated range of the Km values (M1-M5. These formulations were selected as SMEDDS. Results of characterisation pointed out the importance of the type and concentration of the oil as well as the Km value for the self-microemulsying ability as well as drug release kinetics from the investigated SMEDDS. Ibuprofen relase was in accordance with the request of USP 30-NF 25 (at least 80 %, after 60 min from the formulations M1 (Km 9:1 and M5 (Km 1:9. Furthermore, ibuprofen release was

  11. Numerical integration of some new unified plasticity-creep formulations

    Krieg, R.D.

    1977-01-01

    The usual constitutive description of metals at high temperature treats creep as a phenomenon which must be added to time independent phenomena. A new approach is now being advocated by some people, principally metallurgists. They all treat the inelastic strain as a unified quantity, incapable of being separated into time dependent and time independent parts. This paper examines the behavior of the differential formulations reported in the literature together with one proposed by the author. These formulations are capable of representing primary and secondary creep, cyclic hardening to a stable cyclic stress-strain loop, a conventional plasticity behavior, and a Bauchinger effect which may be creep induced and discernable either at fast or slow loading rates. The new unified formulations seem to lead to very non-linear systems of equations which are very well behaved in some regions and very stiff in other regions where the word 'stiff' is used in the mathematical sense. Simple conventional methods of integrating incremental constitutive equations are observed to be totally inadequate. A method of numerically integrating the equations is presented. (Auth.)

  12. Lagrangian formulation of the general relativistic Poynting-Robertson effect

    De Falco, Vittorio; Battista, Emmanuele; Falanga, Maurizio

    2018-04-01

    We propose the Lagrangian formulation for describing the motion of a test particle in a general relativistic, stationary, and axially symmetric spacetime. The test particle is also affected by a radiation field, modeled as a coherent flux of photons traveling along the null geodesics of the background spacetime, including the general relativistic Poynting-Robertson effect. The innovative part of this work is to prove the existence of the potential linked to the dissipative action caused by the Poynting-Robertson effect in general relativity through the help of an integrating factor, depending on the energy of the system. Generally, such kinds of inverse problems involving dissipative effects might not admit a Lagrangian formulation; especially, in general relativity, there are no examples of such attempts in the literature so far. We reduce this general relativistic Lagrangian formulation to the classic case in the weak-field limit. This approach facilitates further studies in improving the treatment of the radiation field, and it contains, for example, some implications for a deeper comprehension of the gravitational waves.

  13. An emergentist vs a linear approach to social change processes: a gender look in contemporary India between modernity and Hindu tradition.

    Condorelli, Rosalia

    2015-01-01

    Using Census of India data from 1901 to 2011 and national and international reports on women's condition in India, beginning with sex ratio trends according to regional distribution up to female infanticides and sex-selective abortions and dowry deaths, this study examines the sociological aspects of the gender imbalance in modern contemporary India. Gender inequality persistence in India proves that new values and structures do not necessarily lead to the disappearance of older forms, but they can co-exist with mutual adaptations and reinforcements. Data analysis suggests that these unexpected combinations are not comprehensible in light of a linear concept of social change which is founded, in turn, on a concept of social systems as linear interaction systems that relate to environmental perturbations according to proportional cause and effect relationships. From this perspective, in fact, behavioral attitudes and interaction relationships should be less and less proportionally regulated by traditional values and practices as exposure to modernizing influences increases. And progressive decreases should be found in rates of social indicators of gender inequality like dowry deaths (the inverse should be found in sex ratio trends). However, data does not confirm these trends. This finding leads to emphasize a new theoretical and methodological approach toward social systems study, namely the conception of social systems as complex adaptive systems and the consequential emergentist, nonlinear conception of social change processes. Within the framework of emergentist theory of social change is it possible to understand the lasting strength of the patriarchal tradition and its problematic consequences in the modern contemporary India.

    Instability of vaccines often emerges as a key challenge during clinical development (lab to clinic) as well as commercial distribution (factory to patient). To yield stable, efficacious vaccine dosage forms for human use, successful formulation strategies must address a combination of interrelated topics including stabilization of antigens, selection of appropriate adjuvants, and development of stability-indicating analytical methods. This review covers key concepts in understanding the causes and mechanisms of vaccine instability including (1) the complex and delicate nature of antigen structures (e.g., viruses, proteins, carbohydrates, protein-carbohydrate conjugates, etc.), (2) use of adjuvants to further enhance immune responses, (3) development of physicochemical and biological assays to assess vaccine integrity and potency, and (4) stabilization strategies to protect vaccine antigens and adjuvants (and their interactions) during storage. Despite these challenges, vaccines can usually be sufficiently stabilized for use as medicines through a combination of formulation approaches combined with maintenance of an efficient cold chain (manufacturing, distribution, storage and administration). Several illustrative case studies are described regarding mechanisms of vaccine instability along with formulation approaches for stabilization within the vaccine cold chain. These include live, attenuated (measles, polio) and inactivated (influenza, polio) viral vaccines as well as recombinant protein (hepatitis B) vaccines. Copyright © 2014 The Authors.

    This report summarizes the consensus findings and recommendations emerging from 2007 Symposium, 'Quality Assurance of Radiation Therapy: Challenges of Advanced Technology.' The Symposium was held in Dallas February 20-22, 2007. The 3-day program, which was sponsored jointly by the American Society for Therapeutic Radiology and Oncology (ASTRO), American Association of Physicists in Medicine (AAPM), and National Cancer Institute (NCI), included >40 invited speakers from the radiation oncology and industrial engineering/human factor communities and attracted nearly 350 attendees, mostly medical physicists. A summary of the major findings follows. The current process of developing consensus recommendations for prescriptive quality assurance (QA) tests remains valid for many of the devices and software systems used in modern radiotherapy (RT), although for some technologies, QA guidance is incomplete or out of date. The current approach to QA does not seem feasible for image-based planning, image-guided therapies, or computer-controlled therapy. In these areas, additional scientific investigation and innovative approaches are needed to manage risk and mitigate errors, including a better balance between mitigating the risk of catastrophic error and maintaining treatment quality, complimenting the current device-centered QA perspective by a more process-centered approach, and broadening community participation in QA guidance formulation and implementation. Industrial engineers and human factor experts can make significant contributions toward advancing a broader, more process-oriented, risk-based formulation of RT QA. Healthcare administrators need to appropriately increase personnel and ancillary equipment resources, as well as capital resources, when new advanced technology RT modalities are implemented. The pace of formalizing clinical physics training must rapidly increase to provide an adequately trained physics workforce for advanced technology RT. The specific

  1. Nuclear weapons modernizations

    Energy Technology Data Exchange (ETDEWEB)

    Kristensen, Hans M. [Federation of American Scientists, Washington, DC (United States)

    2014-05-09

    This article reviews the nuclear weapons modernization programs underway in the world's nine nuclear weapons states. It concludes that despite significant reductions in overall weapons inventories since the end of the Cold War, the pace of reductions is slowing - four of the nuclear weapons states are even increasing their arsenals, and all the nuclear weapons states are busy modernizing their remaining arsenals in what appears to be a dynamic and counterproductive nuclear competition. The author questions whether perpetual modernization combined with no specific plan for the elimination of nuclear weapons is consistent with the nuclear Non-Proliferation Treaty and concludes that new limits on nuclear modernizations are needed.

  2. High-Level Waste Glass Formulation Model Sensitivity Study 2009 Glass Formulation Model Versus 1996 Glass Formulation Model

    2009-01-01

    This document presents the differences between two HLW glass formulation models (GFM): The 1996 GFM and 2009 GFM. A glass formulation model is a collection of glass property correlations and associated limits, as well as model validity and solubility constraints; it uses the pretreated HLW feed composition to predict the amount and composition of glass forming additives necessary to produce acceptable HLW glass. The 2009 GFM presented in this report was constructed as a nonlinear optimization calculation based on updated glass property data and solubility limits described in PNNL-18501 (2009). Key mission drivers such as the total mass of HLW glass and waste oxide loading are compared between the two glass formulation models. In addition, a sensitivity study was performed within the 2009 GFM to determine the effect of relaxing various constraints on the predicted mass of the HLW glass.

    High strength extended release opioid products, which are indispensable tools in the management of pain, are associated with serious risks of unintentional and potentially fatal overdose, as well as of misuse and abuse that might lead to addiction. The issue of drug abuse becomes increasingly prominent when the dosage forms can be readily manipulated to release a high amount of opioid or to extract the drug in certain products or solvents. One approach to deter opioid drug abuse is by providing novel abuse deterrent formulations (ADF), with properties that may be viewed as barriers to abuse of the product. However, unlike regular extended release formulations, assessment of ADF technologies are challenging, in part due to the great variety of formulation designs available to achieve deterrence of abuse by oral, parenteral, nasal and respiratory routes. With limited prior history or literature information, and lack of compendial standards, evaluation and regulatory approval of these novel drug products become increasingly difficult. The present article describes a risk-based standardized in-vitro approach that can be utilized in general evaluation of abuse deterrent features for all ADF products. PMID:26784976

    The analytical formulations on the premixed flame acceleration induced by wall friction in two-dimensional (2D) channels [Bychkov et al., Phys. Rev. E 72 (2005) 046307] and cylindrical tubes [Akkerman et al., Combust. Flame 145 (2006) 206] are revisited. Specifically, pipes with one end closed are considered, with a flame front propagating from the closed pipe end to the open one. The original studies provide the analytical formulas for the basic flame and fluid characteristics such as the flame acceleration rate, the flame shape and its propagation speed, as well as the flame-generated flow velocity profile. In the present work, the accuracy of these approaches is verified, computationally, and the intrinsic limitations and validity domains of the formulations are identified. Specifically, the error diagrams are presented to demonstrate how the accuracy of the formulations depends on the thermal expansion in the combustion process and the Reynolds number associated with the flame propagation. It is shown that the 2D theory is accurate enough for a wide range of parameters. In contrast, the zeroth-order approximation for the cylindrical configuration appeared to be quite inaccurate and had to be revisited. It is subsequently demonstrated that the first-order approximation for the cylindrical geometry is very accurate for realistically large thermal expansions and Reynolds numbers. Consequently, unlike the zeroth-order approach, the first-order formulation can constitute a backbone for the comprehensive theory of the flame acceleration and detonation initiation in cylindrical tubes. Cumulatively, the accuracy of the formulations deteriorates with the reduction of the Reynolds number and thermal expansion.

    Full Text Available Grounded on Bauman’s thought, the present paper focuses on the constitution of social legitimacy and identity of Physical Education in the context of transition from solid to liquid modernity. This thought favors the understanding of the nature of the crisis that has crossed the identity discourse of Physical Education. The text signals the limits and possibilities of both the modern and the post-modern educational discourses. In this context, it describes a modern scenario that is marked by two distinct moments, the one of modernity at its solid stage, and that of modernity at its liquid stage. The first one, of solid modernity, social condition of surveillance, rationalization and control, performs the functional / adaptive role of putting everyone under the same rigid order (managed society. The second one, of liquid modernity, of the social condition of insignificance and irrationalism, plays the functional role of putting and keeping everyone under the same flexible Market disorder. From the scientific, mechanic focus of both the body and the physical education in solid modernity we have moved to the relativist and esthetic focus of body and physical education in liquid modernity.

    The study focused on recognizing the local approaches of farming in designing and implementation of development projects. These approaches are representative of a particular ecological, social, economical, and political system, shaped by the constraints and opportunities associated to the area. Effective and successful development projects must include the local perceptions, their approaches and practices, as the locals are the ones most representative of their issues and have the most workable solution to them. The traditional agriculture has completely been clutched into the nexus of modern farming methods, due to which they are being abandoned by the farmers. Modern farming which is representative of development has increased the competition, transitioning, breaking the community into people experimenting on modern technology and those who are still finding means to adapt their traditional agriculture to the fast changing needs of the societies. The research was carried out in the villages of Ghora Gali and Aruka through qualitative and quantitative methods. Sustainable development in Pakistan thus needs to be reinvented in the local perspective considering approaches and practices and, eradicating the alien chains of development completely. (author)

    Full Text Available The pursuit of antiquity was important for scholarly artists in constructing their knowledge of history and cultural identity in late Imperial China. Following various publications by Bi Yuan 畢沅 (1730-1797, Wu Yi 武億 (1745-1799 and Qian Daxin 錢大昕 (1728-1804 in the 18th century, the study and collecting of rubbings of Northern Wei stone inscriptions and steles was popular. Such spread of interest in jinshi, inscriptions on metal and stone, also formed a base for studying seal carving, epigraphy and archaic painting. While traditional antiquarians would cherish inscriptions which enabled them to correct mistakes in the transmitted historical texts and the Classics, however, much of the antiquarian activity was adapted to mere literary exercise or connoisseurship, for instance, to supplying materials which could provide models for seal-carving and calligraphy. Examples could be seen in the calligraphy works and seal carvings of the Xiling bajia 西泠八家 (Eight Masters of Xiling, i.e. Hangzhou, also known as Zhe School of Calligraphy and Carving. Their keen interest in seeking inspiration from steles for their artistic presentations has been recorded in their writing and painting. In addition, the way the scholar-collector of the 19th and early 20th centuries mounted the rubbings, seals, inscriptions, paintings, letters and textual evidence studies into one album shows a changing ideology: rubbings were not only for scholarly study in classical learning, but were regarded as part of the art form and were appreciated on various social occasions. The antiquarian movement ultimately served as a tool for re-writing art historiography in modern China. This paper aims to address the phenomenon and formation of the jinshi painting that dominated in late Imperial and early modern China. Through case studies of three important jinshi societies in Shanghai, I will investigate in what way literary taste from the southern region gradually

    Full Text Available Fiction, as understood in the West, was not a strong part of the Tibetan literary tradition (Stein 1972, 251-2. Although Newman (1996, 411 has argued that certain literary works existed as early as the eighteenth century, most fictional texts in Tibet belonged to folklore and oral tradition. Beginning in the twentieth century, however, modern fiction and poetry has gradually emerged and even thrives in spite of continuing issues of literacy and education. As relative newcomers to the study of Tibetan writing, western scholars, many of whom approach Tibet from disciplines that emphasize religion or philosophy, tend to overlook modern fiction. This work, edited by Hartley and Schiaffini-Vedani, aims to fill this void and provide scholars with an introduction to the complexities of modern Tibetan literature and how it reflects and impacts the unique transnational and cross-cultural social context it is written in... ...

    Full Text Available Active ingredients in pharmaceuticals differ by their physico-chemical properties and their bioavailability therefore varies. The most frequently used and most convenient way of administration of medicines is oral, however many drugs are little soluble in water. Thus they are not sufficiently effective and suitable for such administration. For this reason a system of lipid based formulations (LBF was developed. Series of formulations were prepared and tested in water and biorelevant media. On the basis of selection criteria, there were selected formulations with the best emulsification potential, good dispersion in the environment and physical stability. Samples of structurally different drugs included in the Class II of the Biopharmaceutics classification system (BCS were obtained, namely Griseofulvin, Glibenclamide, Carbamazepine, Haloperidol, Itraconazol, Triclosan, Praziquantel and Rifaximin, for testing of maximal saturation in formulations prepared from commercially available excipients. Methods were developed for preparation of formulations, observation of emulsification and its description, determination of maximum solubility of drug samples in the respective formulation and subsequent analysis. Saturation of formulations with drugs showed that formulations 80 % XA and 20 % Xh, 35 % XF and 65 % Xh were best able to dissolve the drugs which supports the hypothesis that it is desirable to identify limited series of formulations which could be generally applied for this purpose.

  16. Representation of Emotive Concepts in Modern English Fictional Discourse: Gender Approach

    Directory of Open Access Journals (Sweden)

    Anna I. Dzyubenko

    2016-09-01

    Full Text Available The article reveals the narrative strategies that are applied by the two modern much written about female authors – S. Kinsella and E. Gilbert – that help them create a unique, at times even autonomous world of a female protagonist embodying a concept of a modern woman. By defining the types of emotions introduced to the English female discourse and by determining the set of their verbal realizations grouped in clusters, the author of the article investigates the grammatical structure of the texts, so-called ‘loaded’ with emotions, thus describing the pragmatic potential of the linguistic units through which the text category of emotiveness is realized. The author states the indisputable likeness of the ‘emotional’ palette found in the female narrations that reveals itself in the females’ going through the same emotional ups and downs, through dissatisfaction with herself and with the world around, finally, through overcoming despair and depression and thus coming to happiness and psycho-emotional tranquility. The paper also offers a set of emotive concepts that are most frequently represented in “Undomestic Goddess” and “Eat. Pray. Love” novels alongside with the description of contextual background that made their objectivization within the works mentioned logical and possible. Finally, the article suggests an interpretative view on a woman acting as a protagonist in the narration and as a fictional embodiment of a real typical female.

  17. Narrative medicine: the modern communication between patient and doctor.

    2011-01-01

    In Modern Medicine the ability to communicate represents a true and unique operative methodology which is the basis of Narrative Medicine. This type of approach does not represent an alternative to the traditional model, but rather expands its boundaries while preserving its scientific base; where the feelings, expectations, and desires of the Patient and his interpretation of the disease, more or less obvious, are read in the broad context in which the Patient himself exhibits. Two principle themes in medical training have by now been clearly identified and can be summarized as follows: the ability to understand and to explain (what to say to the patient) and the ability to listen and to comprehend (how to speak to the patient). In this regard the modern Narrative Medicine is a holistic approach to the complexity of the method known as the most effective and most efficient - not only in patient-centered medicine, but also in the improvement of services rendered to both the individual and society at large.

  1. A Post-Modern Portfolio Management Approach on CEE Markets

    Directory of Open Access Journals (Sweden)

    Marcela-Daniela Todoni

    2015-01-01

    Full Text Available In this paper we apply two methods based on the Post-Modern Portfolio Management approach to study the risk-adjusted return of 5 major indices from emerging markets in Central and Eastern Europe during the period 2008-2013 on daily data. First, we involve the Sortino ratio. Secondly we propose an alternative method to the Sortino ratio for calculating the risk-adjusted return using a “multipliers method” to determine a global measure of risk. The Sortino ratio is used to score a portfolio's risk-adjusted returns relative to an investment target using downside risk and it measures the risk-adjusted return of an investment asset, portfolio or strategy. Our proposed alternative method is using the same logic and frame structure as Sortino ratio. However instead of downside risk we use the global risk calculated using multipliers. This is due to the fact that Sortino ratio does not distinguish between sub-cases possible – unrealized return area and loss area (negative return. Because of these we believe that it would be necessary a new method which to refine the results and take and into account the three areas. Our dataset includes 5 emerging markets: Romania (BET, Hungary (BUX, Czech Republic (PX, Bulgaria (SOFIX and Poland (WIG. For each of them we estimate the Sortino ratio of length windows 7, 14, 42 and 10, 21, 60. We used two variants for each target return, namely 2% and 5%. We consider Germany as a benchmark. After estimating the Sortino ratio and global risk calculated using “multipliers method”, we conducted a parallel analysis between Sortino ratio and the proposed alternative method. We split the analysis time span in two sub-periods, 2008-2010 and 2011-2013. As known, the higher the Sortino ratio, the better the risk-adjusted performance. The risk-adjusted return is influenced by the used target return and the used window. Analyzed data reveals that in case of Sortino ratio, Hungary has the best results and on the other side

  2. Market valuation in the framework of modern life insurance mathematics

    Maja Petrač

    2013-12-01

    Full Text Available In the traditional actuarial life insurance mathematics, liabilities to beneficiaries (technical reserves are calculated based on conservative assumptions of mortality and interest rates. However, this approach was found to be incomplete since it does not contain the market component which has become essential due to the development of the financial market. Since about 80% of total liabilities of life insurance companies are made up of technical reserves, this issue has a major impact on the overall performance of insuran - ce companies. The introduction of financial components into the actuarial valuation resulted in actuarial mathematics using more and more the elements of financial mathematics thus creating new, modern life insurance mathematics. Using a simple example, this paper compares the traditional and market approaches to valuation. For this purpose, one of the principles of modern life insurance mathematics, the principle of equivalence, was observed. The above market approach to valuation, together with operational risk management, forms the basis of Solvency II Directive, the new legislative and regulatory framework for insurance and reinsurance companies in the European Union.

  3. Problem formulation for risk assessment of combined exposures to chemicals and other stressors in humans.

    2016-11-01

    When the human health risk assessment/risk management paradigm was developed, it did not explicitly include a "problem formulation" phase. The concept of problem formulation was first introduced in the context of ecological risk assessment (ERA) for the pragmatic reason to constrain and focus ERAs on the key questions. However, this need also exists for human health risk assessment, particularly for cumulative risk assessment (CRA), because of its complexity. CRA encompasses the combined threats to health from exposure via all relevant routes to multiple stressors, including biological, chemical, physical and psychosocial stressors. As part of the HESI Risk Assessment in the 21st Century (RISK21) Project, a framework for CRA was developed in which problem formulation plays a critical role. The focus of this effort is primarily on a chemical CRA (i.e., two or more chemicals) with subsequent consideration of non-chemical stressors, defined as "modulating factors" (ModFs). Problem formulation is a systematic approach that identifies all factors critical to a specific risk assessment and considers the purpose of the assessment, scope and depth of the necessary analysis, analytical approach, available resources and outcomes, and overall risk management goal. There are numerous considerations that are specific to multiple stressors, and proper problem formulation can help to focus a CRA to the key factors in order to optimize resources. As part of the problem formulation, conceptual models for exposures and responses can be developed that address these factors, such as temporal relationships between stressors and consideration of the appropriate ModFs.

  4. Challenges of leadership in modern organizations: knowledge, vision, values

    2014-09-01

    Full Text Available The article highlights the issue of leadership in the context of the exercise in the knowledge-based organization. Connections between organizational culture, management culture and leadership in modern organizations highlight the manner in which leadership is exercised in the context of knowledge of the organization's foundation. Leadership means knowledge and practice, it means quality. Organizations need managers, but they also need leaders. It is desirable for the two areas to overlap in the largest possible extent. Modern approaches emphasize the evolution of these relations to the area where the legitimacy of the leadership's concern is justified by the development and promotion of other leaders.

  5. On Heidegger, medicine, and the modernity of modern medical technology.

    Science.gov (United States)

    Brassington, Iain

    2007-06-01

    This paper examines medicine's use of technology in a manner from a standpoint inspired by Heidegger's thinking on technology. In the first part of the paper, I shall suggest an interpretation of Heidegger's thinking on the topic, and attempt to show why he associates modern technology with danger. However, I shall also claim that there is little evidence that medicine's appropriation of modern technology is dangerous in Heidegger's sense, although there is no prima facie reason why it mightn't be. The explanation for this, I claim, is ethical. There is an initial attraction to the thought that Heidegger's thought echoes Kantian moral thinking, but I shall dismiss this. Instead, I shall suggest that the considerations that make modern technology dangerous for Heidegger are simply not in the character - the ethos - of medicine properly understood. This is because there is a distinction to be drawn between chronological and historical modernity, and that even up-to-date medicine, empowered by technology, retains in its ethos crucial aspects of a historically pre-modern understanding of technology. A large part of the latter half of the paper will be concerned with explaining the difference.

  6. Problem formulation as a discursive design activity

    DEFF Research Database (Denmark)

    Hansen, Claus Thorp; Dorst, Kees; Andreasen, Mogens Myrup

    2009-01-01

    In the design methodology literature, design is often described as a rational problem solving process. This approach has been very successful; it has lead to the creation of design process models, tools, methods and techniques. Design methods teaching along these lines has become an indispensable...... part of any engineering design education. Yet the assumptions behind the rational problem solving approach to design do not sit well with some of the experiences we have in design teaching and design practice. Problem formulation is one such area where we might have to look for a different way...... to describe what is happening in design, beyond the problem solving approach. In this paper an extensive educational case study will be used to see whether a framework for describing design as a discursive activity (based on the notions of ‘discourse’ and ‘paradox’) could be more appropriate to describe...

    Water supply and water management in Antiquity represent more than Modern World can imagine about how people in that period used to think about, and exploit the resources they had, aiming at developing and improving their society and own lives. This paper points out examples of how they handled different situations, and how they managed to cope with the growing number of population in the urban areas, by adapting or by improving their water supply systems. The paper tries to emphasize the engineering contribution of Rome and the Roman Empire, mainly in the capital but also in the provinces, as for instance the today territory of France, by analysing some aqueducts from the point of view of modern Hydraulic Engineering. A third order polynomial regression is proposed to compute the water flow rate, based on the flow cross-sectional area measured in quinaria. This paper also emphasizes on contradictory things between what we thought we knew about Ancient Roman civilization, and what could really be proven, either by a modern engineering approach, a documentary approach, or by commonsense, where none of the above could be used. It is certain that the world we live in is the heritage of the Greco-Roman culture and therefore, we are due to acknowledge their contribution, especially taking into account the lack of knowledge of that time, and the poor resources they had.

  9. A general real-time formulation for multi-rate mass transfer problems

    O. Silva

    2009-08-01

    Full Text Available Many flow and transport phenomena, ranging from delayed storage in pumping tests to tailing in river or aquifer tracer breakthrough curves or slow kinetics in reactive transport, display non-equilibrium (NE behavior. These phenomena are usually modeled by non-local in time formulations, such as multi-porosity, multiple processes non equilibrium, continuous time random walk, memory functions, integro-differential equations, fractional derivatives or multi-rate mass transfer (MRMT, among others. We present a MRMT formulation that can be used to represent all these models of non equilibrium. The formulation can be extended to non-linear phenomena. Here, we develop an algorithm for linear mass transfer, which is accurate, computationally inexpensive and easy to implement in existing groundwater or river flow and transport codes. We illustrate this approach by application to published data involving NE groundwater flow and solute transport in rivers and aquifers.

My contribution supports this thesis by analyzing the world of things in Hans Christian Andersen's fairy tales. Exemplary readings reveal how Andersen's texts acknowledge the power of things in modern life and how these texts thus question scientific and philosophical concepts of subjectivity that dominated in the nineteenth century. The agency of things in Andersen's texts challenges the ideal of a rational subject that acts autonomously. Current theoretical approaches, notably Actor-Network-Theory, allow us to understand the realism of acting things in Andersen's work.

    Full Text Available As it is known, one of the significant issues of Divan Literature is the issue of annotating a text. Especially, the lack of a common method in traditional text annotations led many researchers to the quest of new methods. Such names as Ali Nihat Tarlan, Haluk İpekten, Cem Dilçin, Tunca Kortantamer not only attached importance to traditional text annotation but also did studies that fed from our present time literary theories and supported studies in this context. Studies on modern text analysis have not become widespread in the field of classical Turkish Literature. Thus the Classical Turkish Literature was unable to form an "annotation method" applied in text annotation studies using together the traditional and modern approaches. Poem analysis method that began with Mehmet Kaplan in the field of New Turkish Literature continues with new searches in our present time. One of the names that continue these searches is Prof. Dr. Nurullah Çetin “The Poem Analysis Method" suggested by him will be applied on a ghazal of Hafız and the method in question will be carried out.

    2007-10-02

    A decontamination formulation and method of making that neutralizes the adverse health effects of both chemical and biological compounds, especially chemical warfare (CW) and biological warfare (BW) agents, and toxic industrial chemicals. The formulation provides solubilizing compounds that serve to effectively render the chemical and biological compounds, particularly CW and BW compounds, susceptible to attack, and at least one reactive compound that serves to attack (and detoxify or kill) the compound. The formulation includes at least one solubilizing agent, a reactive compound, a sorbent additive, and water. A highly adsorbent sorbent additive (e.g., amorphous silica, sorbitol, mannitol, etc.) is used to "dry out" one or more liquid ingredients into a dry, free-flowing powder that has an extended shelf life, and is more convenient to handle and mix in the field.

  14. Formulation and demonstration of a robust mean variance optimization approach for concurrent airline network and aircraft design

    Science.gov (United States)

    Davendralingam, Navindran

    Conceptual design of aircraft and the airline network (routes) on which aircraft fly on are inextricably linked to passenger driven demand. Many factors influence passenger demand for various Origin-Destination (O-D) city pairs including demographics, geographic location, seasonality, socio-economic factors and naturally, the operations of directly competing airlines. The expansion of airline operations involves the identificaion of appropriate aircraft to meet projected future demand. The decisions made in incorporating and subsequently allocating these new aircraft to serve air travel demand affects the inherent risk and profit potential as predicted through the airline revenue management systems. Competition between airlines then translates to latent passenger observations of the routes served between OD pairs and ticket pricing---this in effect reflexively drives future states of demand. This thesis addresses the integrated nature of aircraft design, airline operations and passenger demand, in order to maximize future expected profits as new aircraft are brought into service. The goal of this research is to develop an approach that utilizes aircraft design, airline network design and passenger demand as a unified framework to provide better integrated design solutions in order to maximize expexted profits of an airline. This is investigated through two approaches. The first is a static model that poses the concurrent engineering paradigm above as an investment portfolio problem. Modern financial portfolio optimization techniques are used to leverage risk of serving future projected demand using a 'yet to be introduced' aircraft against potentially generated future profits. Robust optimization methodologies are incorporated to mitigate model sensitivity and address estimation risks associated with such optimization techniques. The second extends the portfolio approach to include dynamic effects of an airline's operations. A dynamic programming approach is

    The purpose of the present study is to optimize a spray-dried formulation as a model antibody regarding stability and aerodynamic property for further aerosol therapy of this group of macromolecules. A three-factor, three-level, Box-Behnken design was employed milligrams of Cysteine (X 1 ), Trehalose (X 2 ), and Tween 20 (X 3 ) as independent variables. The dependent variables were quantified and the optimized formulation was prepared accordingly. SEC-HPLC and FTIR-spectroscopy were conducted to evaluate the molecular and structural status of spray-dried preparations. Particle characterization of optimized sample was performed with the aid of DSC, SEM, and TSI examinations. Experimental responses of a total of 17 formulations resulted in yield values, (Y 1 ), ranging from 21.1 ± 0.2 to 40.2 ± 0.1 (%); beta-sheet content, (Y 2 ), from 66.22 ± 0.19 to 73.78 ± 0.26 (%); amount of aggregation following process, (Y 3 ), ranging from 0.11 ± 0.03 to 0.95 ± 0.03 (%); and amount of aggregation upon storage, (Y 4 ), from 0.81 ± 0.01 to 3.13 ± 0.64 (%) as dependent variables. Results-except for those of the beta sheet content-were fitted to quadratic models describing the inherent relationship between main factors. Co-application of Cysteine and Tween 20 preserved antibody molecules from molecular degradation and improved immediate and accelerated stability of spry-dried antibodies. Validation of the optimization study indicated high degree of prognostic ability of response surface methodology in preparation of stable spray-dried IgG.

  16. A Review and Modern Approach to LC Ladder Synthesis

    2011-01-01

    Full Text Available Ultra low power circuits require robust and reliable operation despite the unavoidable use of low currents and the weak inversion transistor operation region. For analogue domain filtering doubly terminated LC ladder based filter topologies are thus highly desirable as they have very low sensitivities to component values: non-exact component values have a minimal effect on the realised transfer function. However, not all transfer functions are suitable for implementation via a LC ladder prototype, and even when the transfer function is suitable the synthesis procedure is not trivial. The modern circuit designer can thus benefit from an updated treatment of this synthesis procedure. This paper presents a methodology for the design of doubly terminated LC ladder structures making use of the symbolic maths engines in programs such as MATLAB and MAPLE. The methodology is explained through the detailed synthesis of an example 7th order bandpass filter transfer function for use in electroencephalogram (EEG analysis.

    2009-01-01

    Long Day's journey into Night may seem a strange starting place for a feminist analysis of modernism and post-modernism. Yet even the most conservative criticism reads this play as an enactment and embodiment of loss, specifically loss of the mother. That loss is rarely seen in the context of a more general "loss", a cultural loss of legitimacy and authenticity, endemic in and enabling modernism, articulated as "disinheritance" by an Other "coded as feminine."

    Full Text Available For many countries and regions (both in Russia and abroad, natural resources are the crucial factor for socio-economic development. The role and significance of natural resources in the economy of different areas substantially depend on the institutional environment, including the resource regime. Today, we have a qualitative complication of conditions for mineral resources exploitation, we start to develop new, non-traditional types of resources, which haven’t been available (or demanded earlier for the economic and technological reasons. The changes in the characteristics of natural objects, as well as the increasing of uncertainty in the resource sector, actualize the search for alternatives of the development of resource-type regions and for the elaboration of appropriate strategies. In new conditions of resource regions, it is necessary to place emphasis on the aspects of expanded specific understanding of inclusiveness. It implies the possibility of active participation of regional authorities in the management and regulation of the mineral complex, as well as their involvement in the development of the association of a wide range of communities. These communities consist of the organizations representing the interests of indigenous peoples as well as professional communities: industry associations, environmental organizations, representatives of the innovation industry. Modern approaches to the elaboration of strategic directions for the resource regions development (primarily based on the development of the mineral industry should be based on sustainable development principles, the principles of inclusiveness and the need for innovations. As a result of the convergence of these characteristics, a new socio-economic concept is formed. This concept can be defined as the harmonious development that is extremely important for the Russian regions. The proposed approach can be used for the elaboration of strategic alternatives of the

  19. Neonates need tailored drug formulations.

    2013-02-08

    Drugs are very strong tools used to improve outcome in neonates. Despite this fact and in contrast to tailored perfusion equipment, incubators or ventilators for neonates, we still commonly use drug formulations initially developed for adults. We would like to make the point that drug formulations given to neonates need to be tailored for this age group. Besides the obvious need to search for active compounds that take the pathophysiology of the newborn into account, this includes the dosage and formulation. The dosage or concentration should facilitate the administration of low amounts and be flexible since clearance is lower in neonates with additional extensive between-individual variability. Formulations need to be tailored for dosage variability in the low ranges and also to the clinical characteristics of neonates. A specific focus of interest during neonatal drug development therefore is a need to quantify and limit excipient exposure based on the available knowledge of their safety or toxicity. Until such tailored vials and formulations become available, compounding practices for drug formulations in neonates should be evaluated to guarantee the correct dosing, product stability and safety.

    2017-10-03

    Team formulation is promoted by professional practice guidelines for clinical psychologists. However, it is unclear whether team formulation is understood/implemented in consistent ways - or whether there is outcome evidence to support the promotion of this practice. This systematic review aimed to (1) synthesize how team formulation practice is defined and implemented by practitioner psychologists and (2) analyse the range of team formulation outcomes in the peer-reviewed literature. Seven electronic bibliographic databases were searched in June 2016. Eleven articles met inclusion criteria and were quality assessed. Extracted data were synthesized using content analysis. Descriptions of team formulation revealed three main forms of instantiation: (1) a structured, consultation approach; (2) semi-structured, reflective practice meetings; and (3) unstructured/informal sharing of ideas through routine interactions. Outcome evidence linked team formulation to a range of outcomes for staff teams and service users, including some negative outcomes. Quality appraisal identified significant issues with evaluation methods; such that, overall, outcomes were not well-supported. There is weak evidence to support the claimed beneficial outcomes of team formulation in practice. There is a need for greater specification and standardization of 'team formulation' practices, to enable a clearer understanding of any relationships with outcomes and implications for best-practice implementations. Under the umbrella term of 'team formulation', three types of practice are reported: (1) highly structured consultation; (2) reflective practice meetings; and (3) informal sharing of ideas. Outcomes linked to team formulation, including some negative outcomes, were not well evidenced. Research using robust study designs is required to investigate the process and outcomes of team formulation practice. © 2017 The British Psychological Society.

  2. Topical formulations with superoxide dismutase: influence of formulation composition on physical stability and enzymatic activity.

    2003-04-24

    Three different topical formulations were supplemented with superoxide dismutase (SOD) and evaluated concerning physical and chemical stabilities in order to determine the most stable formulation that would maintain SOD activity. Physical stability was evaluated by storing the formulation at room temperature, and at 37 and 45 degrees C for 28 days. Samples were collected at 7-day intervals for assessment of rheological behavior. Chemical stability was evaluated by the measurement of enzymatic activity in formulations stored at room temperature and at 45 degrees C for 75 days. The formulations showed a pseudoplastic behavior, with a flow index of less than 1. There was no significant difference in the initial values of flow index, hysteresis loop or minimum apparent viscosity. The simple emulsion and the one stabilized with hydroxyethylcellulose showed decreased viscosity by the 21st day and with higher temperature, but no significant changes concerning the presence of SOD. Although there were no significant changes concerning storage time or temperature, the formulation stabilized with hydroxyethylcellulose showed a marked loss of SOD activity. The addition of SOD to the formulations studied did not affect their physical stability. Simple emulsions or emulsions stabilized with carboxypolymethylene seem to be better bases for enzyme addition than emulsion stabilized with hydroxyethylcellulose.

    Full Text Available We are living in an environment, where information flow is freer than ever. Nowadays everyone has access to global news and can make their own conclu-sions based on the perceived image. Therefore, the role of perception and image is becoming more important for different countries to attract visitors and in-vestors. Tourism is a way of selling the image of a country and the reputation and word of mouth generated from tourism activities are priceless to the image of a destination. This paper analyzes the case of Estonia, which is an emerging tourism market and quite new and unknown for Spain. The authors try to accent the importance of direct promotion, through a survey carried out to 341 Spanish people in Madrid. The result from this quantitative and formulative research method is that Estonia has to promote its tourism image better if the country wants to attract the Spanish tourist.

    2010-05-01

    The efficacy of microneedles in the area of transdermal drug delivery is well documented. Multiple studies have shown that enhancement of skin permeation by means of the creation of microscopic pores in the stratum corneum can greatly improve the delivery rates of drugs. However, skin pretreatment with microneedles is not the only factor affecting drug transport rates. Other factors, including drug formulation and rate of micropore closure, are also important for optimizing delivery by this route. This review aims to highlight work that has been done in these areas, with an emphasis on drug formulation parameters that affect transdermal flux. This review creates an appreciation for the many factors affecting microneedle-enhanced delivery. Most results clearly indicate that microneedle skin pretreatment by itself may have different effects on drug transport depending on the formulation used, and formulation characteristics have different effects on the transport through untreated skin and microneedle-treated skin. Several formulation approaches are reported to optimize microneedle-enhanced drug delivery, including co-solvent use, vesicular, nanoparticulate and gel systems. In addition to well-established factors that affect microneedle-assisted delivery (geometry, type of microneedle, etc.), formulation and pore viability are also critical factors that must be considered.

    Full Text Available The article is devoted to the analysis of the phenomenon of «Patchwork-Religiosität» in today’s youth, which is popular in the Western religious studies. The author believes that the «Patchwork-Religiosität» is one of the essential features of the current religious situation. There are three main aspects of the analysis: substantial, functional and discursive. In the first part of the article the author examines the comprehension of the content of the phenomenon of «Patchwork-Religiosität» in modern German theology, sociology and psychology of religion. In the second part different approaches, in which this phenomenon becomes a matter of analysis, are discussed as sociological incident, as a problem of church organizations and as a challenge to theology. As a result, the author shows that the «Patchwork-Religiosität» has become one of the most eff ective forms of resistance to the charms of the world based on material of German research. At the same time, this phenomenon is a real challenge to traditional religious communities in Germany for the past 25 years. Not only sociological approaches play a significant role in learning but also psychological approaches. The focus of this article is a review of some religious trends among young people in the context of modern German experience. It can be noted that the actual scientific topic is one of the most important tendency in the religious life of today’s young people: the presence of secularization and appearance of a particular kind of religiosity. This kind of religiosity needs unique religious experience characterized by the following three common features: a subcultural context i.e. religious self-determination within a certain subculture; b the singular gap i.e. a total departure from traditional notions of religion itself and Christianity in particular, and as a result, the rejection of «the faith of the fathers»; c Lastly, «Patchwork-identity» or

    2017-01-01

    Full Text Available A fourth order formulation of the displacement discontinuity method (DDM is proposed for the crack analysis of brittle solids such as rocks, glasses, concretes and ceramics. A fourth order boundary collocation scheme is used for the discretization of each boundary element (the source element. In this approach, the source boundary element is divided into five sub-elements each recognized by a central node where the displacement discontinuity components are to be numerically evaluated. Three different formulating procedures are presented and their corresponding discretization schemes are discussed. A new discretization scheme is also proposed to use the fourth order formulation for the special crack tip elements which may be used to increase the accuracy of the stress and displacement fields near the crack ends. Therefore, these new crack tips discretizing schemes are also improved by using the proposed fourth order displacement discontinuity formulation and the corresponding shape functions for a bunch of five special crack tip elements. Some example problems in brittle fracture mechanics are solved for estimating the Mode I and Mode II stress intensity factors near the crack ends. These semi-analytical results are compared to those cited in the fracture mechanics literature whereby the high accuracy of the fourth order DDM formulation is demonstrated.

    Mroz, Tomasz M.

    2008-01-01

    New approach to community heating systems modernization and development planning process has been proposed. It is based on the general decision making aid algorithm. The proposed algorithm takes into account both demand and supply side of community heat market modernization and development. The first step of algorithm - analytical step, refers to data base creation, which is needed for the description of community heating system energy, ecology and economic characteristics. Analysis of those characteristics allows for the identification of heating system market modernization and development potential scenarios. The second algorithm step - decision step, allows for the identification of the most compromise scenarios of system modernization and development. To make the planning process more transparent and to increase the influence of decision makers on the planning process the ELECTRE III method was chosen as the tool of decision aid. The ELECTRE III method is based on the construction of outranking relation and definition of pseudo-criterion. The iteration mode of method application allows the decision maker and analyst for the investigation of the sensitivity of final solution to the changing preference model. One of the methods of statistics - the creditability of mean range method was used for the determination of initial definition of pseudo-criterion. Proposed algorithm and decision aid method were employed for the case study analysis referring to the choice of the heating system for new developing urban area. (author)

    2013-05-01

    Worldwide discrepancies in the classification, terminology and diagnosis of mental disorders have induced efforts for unification after World War II. This led to the introduction of an operational diagnostic approach according to strict criteria, at the same time taking into account the comorbidity of disorders. However, this approach is still not routinely used. The consequences of this deficiency are demonstrated here by an example from biographical research referring to the Bavarian King Ludwig II. The study is based on an extensive search of the relevant literature. Although the pathography of this Bavarian king is well documented, the diagnoses published between 1910 and 2010 by altogether 21 specialists, are distributed rather chaotically over 24 diagnostic categories of the ICD-10. Merely in the (probably wrong) diagnosis of a schizophrenic psychosis is there agreement among half of the authors. This is concordant with the expert diagnosis of paranoia by von Gudden and his colleagues (1886) when considering the then contemporary concept of the disorder. According to modern diagnostic principles almost half of the 24 diagnoses can be confirmed. The others have to be regarded as false diagnoses. The conclusion is that modern principles of the diagnosis of mental disorders should be applied according to internationally accepted diagnostic manuals. This approach should be used in, but is not exclusive to, biographical research. Precondition is, of course, the exact knowledge and careful application of these principles.

  12. The Divergence Hypothesis in Modernization Theory Across Three European Countries: the UK, Sweden and Greece

    Directory of Open Access Journals (Sweden)

    Stefania Kalogeraki

    2009-06-01

    Full Text Available Following a comparative approach it is argued that the modernizing trajectories of three European countries, i.e., the UK, Sweden and Greece were different, as the cultural heritages of the three countries under study, formed by specific historical, political and religious events have acted as a filter of their modernization processes and left an imprint on the prevailing values. England followed a type of modernization associated with “bourgeois revolutions”, Sweden was highly influenced by the popular belief system of solidarity of the political culture of Scandinavian nations and Greece, although increasingly modern, can be associated with a more traditional, top to bottom, version of modernization, highly influenced by the Greek Orthodox Church. Secondary data and empirical research show that the different modernizing paths in the three countries have formed their main cultural characteristics; the UK is portrayed as an individualistic culture,Sweden as an amalgamation of both individualism and collectivism, and Greece as a traditional and more collectivist one. As culture, in the Parsonian approach, acts as the binder of the social world it has functioned as a mediating mechanism, shaping the personality traits and social relationships among British, Swedish and Greek citizens in the direction of an individualistic and/or a collectivist ethos. Whilst the thesis of the article does not support the bipolarity of the “divergence” and “convergence” hypotheses it provides some evidence to the former suggesting that modernization does not always take a simple linear path providing no room for variations.

    Electric power is America's most capital-intensive industry, with more than $100 billion invested each year in energy infrastructure. Investment needs are likely to grow as electric utilities make power systems more reliable and resilient, deploy advanced digital technologies, and facilitate new services to meet some consumers' expectations for greater choice and control. But do current regulatory approaches provide the appropriate incentives for grid modernization investments? This report presents three perspectives: -Financial analyst Steve Kihm begins by explaining that any major investor-owned electric utility that wants to raise capital today can do so at a reasonable cost. The question is whether utility managers want to raise capital for grid modernization. Specifically, they look for investments that create the most value for their existing shareholders. In cases where grid modernization investments are not the best choice in terms of shareholder value, Kihm describes shareholder incentive mechanisms that regulators could consider to encourage such investments when they are in the public interest. -From an institutional perspective, Dr. Janice Beecher finds that the traditional rate-base/rate of return regulatory model provides powerful incentives for utilities to pursue investments, cost control, efficiency and even innovation, and it is well suited to the policy objectives of grid modernization. Prudence of grid modernization investments (fair returns) depends on careful evaluation of the specific asset, and any special incentives (bonus returns) should be used only if they promote economic efficiency consistent with the core goals of economic regulation. According to Beecher, realizing the promises of grid modernization depends on effective implementation of the traditional regulatory model and ratemaking tools to serve the public interest. -Conversely, former commissioner and clean energy consultant Ron Lehr says that rapid electric industry

    Spray drying is a promising method for the stabilization of vaccines, which are usually formulated as liquids. Usually, vaccine stability is improved by spray drying in the presence of a range of excipients. Unlike freeze drying, there is no freezing step involved, thus the damage related to this step is avoided. The edge of spray drying resides in its ability for particles to be engineered to desired requirements, which can be used in various vaccine delivery methods and routes. Although several spray dried vaccines have shown encouraging preclinical results, the number of vaccines that have been tested in clinical trials is limited, indicating a relatively new area of vaccine stabilization and delivery. This article reviews the current status of spray dried vaccine formulations and delivery methods. In particular it discusses the impact of process stresses on vaccine integrity, the application of excipients in spray drying of vaccines, process and formulation optimization strategies based on Design of Experiment approaches as well as opportunities for future application of spray dried vaccine powders for vaccine delivery.

    2010-01-01

    The purpose of this work is to assess the hanging drop technique in screening excipients to develop optimal formulations for human immunoglobulin G (IgG). A microdrop of human IgG and test solution hanging from a cover slide and undergoing vapour diffusion was monitored by a stereomicroscope. Aqueous solutions of IgG in the presence of different pH, salt concentrations and excipients were prepared and characterized. Low concentration of either sodium/potassium phosphate or McIlvaine buffer favoured the solubility of IgG. Addition of sucrose favoured the stability of this antibody while addition of NaCl caused more aggregation. Antimicrobial preservatives were also screened and a complex effect at different buffer conditions was observed. Dynamic light scattering, differential scanning calorimetry and size exclusion chromatography studies were performed to further validate the results. In conclusion, hanging drop is a very easy and effective approach to screen protein formulations in the early stage of formulation development.

  17. Approaches to pre-formulation R and D for phytopharmaceuticals emanating from herb based traditional Ayurvedic processes

    Full Text Available Botanicals constitute a large part of the drugs from the traditional medicine (TM and ethno medicine (EM known for their history of safe use (HOSU. Phytopharmaceuticals having a base of such origin offer high advantages as they come with safety profiles, and often allow extrapolation of the HOSU data, under certain circumstances. However, while current pharmaceutical technologies are being adopted by the industry to make phytopharmaceuticals with such origin, there is a need for preformulation research and development (R and D during formulation. Some suggestions for R and D studies in case of aqueous extracts known in Ayurveda, converted on an industrial scale to obtain a phytopharmaceutical, and formulated as a solid dosage form (granules, tablets, or capsules are discussed.

  18. Terbinafine: novel formulations that potentiate antifungal activities.

    Science.gov (United States)

    Ma, Y; Chen, X; Guan, S

    2015-03-01

    Terbinafine, an orally and topically active antifungal agent, has been available for the treatment of dermatophytic infections and onychomycosis for more than a decade. In addition, oral administration has been shown to be associated with drug-drug interactions, hepatotoxicity, low concentration at the infected sites, gastrointestinal and systemic side effects and other adverse effects. Since topical drug delivery can provide higher patient compliance, allow immediate access to the infected site and reduce unwanted systemic drug exposure, an improved topical drug delivery approach with high permeability, sustained release and prolonged retainment could overcome the limitations and side effects caused by oral administration. Conventional topical formulations cannot keep the drug in the targeted sites for a long duration of time and hence a novel drug delivery that can avoid the side effects while still providing sustained efficacy in treatment should be developed. This brief review of novel formulations based on polymers and nanostructure carriers provides insight into the efficacy and topical delivery of terbinafine.

  19. A new LP formulation of the admission control problem modelled as an MDP under average reward criterion

    Science.gov (United States)

    Pietrabissa, Antonio

    2011-12-01

    The admission control problem can be modelled as a Markov decision process (MDP) under the average cost criterion and formulated as a linear programming (LP) problem. The LP formulation is attractive in the present and future communication networks, which support an increasing number of classes of service, since it can be used to explicitly control class-level requirements, such as class blocking probabilities. On the other hand, the LP formulation suffers from scalability problems as the number C of classes increases. This article proposes a new LP formulation, which, even if it does not introduce any approximation, is much more scalable: the problem size reduction with respect to the standard LP formulation is O((C + 1)2/2 C ). Theoretical and numerical simulation results prove the effectiveness of the proposed approach.

  20. GHS additivity formula: can it predict the acute systemic toxicity of agrochemical formulations that contain acutely toxic ingredients?

    Science.gov (United States)

    Van Cott, Andrew; Hastings, Charles E; Landsiedel, Robert; Kolle, Susanne; Stinchcombe, Stefan

    2018-02-01

    In vivo acute systemic testing is a regulatory requirement for agrochemical formulations. GHS specifies an alternative computational approach (GHS additivity formula) for calculating the acute toxicity of mixtures. We collected acute systemic toxicity data from formulations that contained one of several acutely-toxic active ingredients. The resulting acute data set includes 210 formulations tested for oral toxicity, 128 formulations tested for inhalation toxicity and 31 formulations tested for dermal toxicity. The GHS additivity formula was applied to each of these formulations and compared with the experimental in vivo result. In the acute oral assay, the GHS additivity formula misclassified 110 formulations using the GHS classification criteria (48% accuracy) and 119 formulations using the USEPA classification criteria (43% accuracy). With acute inhalation, the GHS additivity formula misclassified 50 formulations using the GHS classification criteria (61% accuracy) and 34 formulations using the USEPA classification criteria (73% accuracy). For acute dermal toxicity, the GHS additivity formula misclassified 16 formulations using the GHS classification criteria (48% accuracy) and 20 formulations using the USEPA classification criteria (36% accuracy). This data indicates the acute systemic toxicity of many formulations is not the sum of the ingredients' toxicity (additivity); but rather, ingredients in a formulation can interact to result in lower or higher toxicity than predicted by the GHS additivity formula.

    Full Text Available Keyhaneh Karimi, Edina Pallagi, Piroska Szabó-Révész, Ildikó Csóka, Rita Ambrus Faculty of Pharmacy, Institute of Pharmaceutical Technology and Regulatory Affairs, University of Szeged, Szeged, Hungary Abstract: Pulmonary drug delivery of ciprofloxacin hydrochloride offers effective local antibacterial activity and convenience of easy application. Spray drying is a trustworthy technique for the production of ciprofloxacin hydrochloride microparticles. Quality by design (QbD, an up-to-date regulatory-based quality management method, was used to predict the final quality of the product. According to the QbD-based theoretical preliminary parameter ranking and priority classification, dry powder inhalation formulation tests were successfully performed in practice. When focusing on the critical parameters, the practical development was more effective and was in correlation with our previous findings. Spray drying produced spherical microparticles. The dry powder formulations prepared were examined by particle size analysis, scanning electron microscopy, Fourier-transform infrared spectroscopy, X-ray powder diffraction, differential scanning calorimetry, and in vitro drug release and aerodynamic particle size analyses were also performed. These formulations showed an appropriate particle size ranging between 2 and 4 µm and displayed an enhanced aerosol performance with fine particle fraction up to 80%.

    Chopra, Arvind; Saluja, Manjit; Tillu, Girish

    2010-07-01

    The potential of Ayurvedic philosophy and medicines needs to be recognized and converted into real life treatment paradigm. This article describes a comprehensive therapeutic approach used in Ayurveda and modern medicine to treat arthritis. We present concise summary of various controlled drug trials carried out by us to validate standardized Ayurvedic drugs using modern medicine protocol to treat Rheumatoid Arthritis and Osteoarthritis knees. Several of the latter are published. The trials consistently demonstrate excellent safety of Ayurvedic medicines but often fail to unequivocally show superior efficacy. Some key findings of a recently unpublished trial in OA knees are also presented to show equivalence between Ayurvedic medicine and celecoxib and glucosamine, and we speculate that equivalence trials may be a way forward. The data from the trials also supports the Ayurvedic 'Rasayana' concept of immune-modulation and healing. We need to interpret logic of Ayurveda when, adopting modern science tools in drug development and validation and much research is required. Validation of Ayurvedic medicines using the latter approach may lead to an evidence based Ayurveda - Modern Medicine interface. Also, in pursuit of finding better treatment solutions, we ought to step beyond the realm of only drugs and attempt validation of comprehensive specific treatment package as per classical Ayurveda. Finally, validation of a combined (Ayurveda and modern medicine) therapeutic approach with superior efficacy and safety is likely to be a major leap in overcoming some of the current frustrations to treat difficult disorders like arthritis using only modern medicines.

    2011-03-14

    We show the exact expression of the quantum mechanical time correlation function in the phase space formulation of quantum mechanics. The trajectory-based dynamics that conserves the quantum canonical distribution-equilibrium Liouville dynamics (ELD) proposed in Paper I is then used to approximately evaluate the exact expression. It gives exact thermal correlation functions (of even nonlinear operators, i.e., nonlinear functions of position or momentum operators) in the classical, high temperature, and harmonic limits. Various methods have been presented for the implementation of ELD. Numerical tests of the ELD approach in the Wigner or Husimi phase space have been made for a harmonic oscillator and two strongly anharmonic model problems, for each potential autocorrelation functions of both linear and nonlinear operators have been calculated. It suggests ELD can be a potentially useful approach for describing quantum effects for complex systems in condense phase.

    Thomassen, Bjørn

    What Europe? Eric Voegelin on the Mediterranean and the Atlantic modernities. The concept ‘multiple modernities’ has during the last decade established itself in social and political theory, not least due to contributions made by Shmul Eisenstadt. The debate on multiple moderntities has served...... to question certain eurocentric assumptions about modernity and has also reignited the question of European particularity in a world historical perspective. This paper will discuss how ‘Europe’ itself can be considered a result of (at least) two different modernities, as proposed by the political theorist......, Eric Voegelin. Eric Voegelin talked of two spatio-temporal specific modernities, the Mediterranean and the Atlantic modernities. In short, for Voegelin the Atlantic modernity with its breakthroughs in the 17th and 18th centuries was a specific figuration that should not be mistaken for ‘modernity...

    2010-01-01

    This article deals with the concept of modernity upon which one of the most interesting contemporary theories about modern social change is based - Peter Wagner's theory of successive modernities. Wagner understands modernity as a double imaginary signification which entails a basic tension between...... liberty and discipline. This conception is almost directly taken from Cornelius Castoriadis. I argue that this tension exists in two versions in Castoriadis' philosophy and that the two versions are incompatible. It is further claimed that the two versions reappear in Wagner's theory, which makes his...... theory of successive modernities partly inconsistent. A stance is taken for one of these versions and it is argued that the theory of successive modernities should appropriate that version as its point of departure in order to grasp the history of modernity in a consistent way.

  8. Approaching the basis set limit for DFT calculations using an environment-adapted minimal basis with perturbation theory: Formulation, proof of concept, and a pilot implementation

    2016-01-01

    Recently developed density functionals have good accuracy for both thermochemistry (TC) and non-covalent interactions (NC) if very large atomic orbital basis sets are used. To approach the basis set limit with potentially lower computational cost, a new self-consistent field (SCF) scheme is presented that employs minimal adaptive basis (MAB) functions. The MAB functions are optimized on each atomic site by minimizing a surrogate function. High accuracy is obtained by applying a perturbative correction (PC) to the MAB calculation, similar to dual basis approaches. Compared to exact SCF results, using this MAB-SCF (PC) approach with the same large target basis set produces <0.15 kcal/mol root-mean-square deviations for most of the tested TC datasets, and <0.1 kcal/mol for most of the NC datasets. The performance of density functionals near the basis set limit can be even better reproduced. With further improvement to its implementation, MAB-SCF (PC) is a promising lower-cost substitute for conventional large-basis calculations as a method to approach the basis set limit of modern density functionals.

  10. A generalized transport-velocity formulation for smoothed particle hydrodynamics

    2017-05-15

    The standard smoothed particle hydrodynamics (SPH) method suffers from tensile instability. In fluid-dynamics simulations this instability leads to particle clumping and void regions when negative pressure occurs. In solid-dynamics simulations, it results in unphysical structure fragmentation. In this work the transport-velocity formulation of Adami et al. (2013) is generalized for providing a solution of this long-standing problem. Other than imposing a global background pressure, a variable background pressure is used to modify the particle transport velocity and eliminate the tensile instability completely. Furthermore, such a modification is localized by defining a shortened smoothing length. The generalized formulation is suitable for fluid and solid materials with and without free surfaces. The results of extensive numerical tests on both fluid and solid dynamics problems indicate that the new method provides a unified approach for multi-physics SPH simulations.

  11. Cerebral localization in the nineteenth century--the birth of a science and its modern consequences.

    Science.gov (United States)

    Steinberg, David A

    2009-07-01

    Although many individuals contributed to the development of the science of cerebral localization, its conceptual framework is the work of a single man--John Hughlings Jackson (1835-1911), a Victorian physician practicing in London. Hughlings Jackson's formulation of a neurological science consisted of an axiomatic basis, an experimental methodology, and a clinical neurophysiology. His axiom--that the brain is an exclusively sensorimotor machine--separated neurology from psychiatry and established a rigorous and sophisticated structure for the brain and mind. Hughlings Jackson's experimental method utilized the focal lesion as a probe of brain function and created an evolutionary structure of somatotopic representation to explain clinical neurophysiology. His scientific theory of cerebral localization can be described as a weighted ordinal representation. Hughlings Jackson's theory of weighted ordinal representation forms the scientific basis for modern neurology. Though this science is utilized daily by every neurologist and forms the basis of neuroscience, the consequences of Hughlings Jackson's ideas are still not generally appreciated. For example, they imply the intrinsic inconsistency of some modern fields of neuroscience and neurology. Thus, "cognitive imaging" and the "neurology of art"--two topics of modern interest--are fundamentally oxymoronic according to the science of cerebral localization. Neuroscientists, therefore, still have much to learn from John Hughlings Jackson.

    2011-09-01

    The scope of this work was to illustrate what dietary modernity represents for sociology and anthropology, which is a subject based on a bibliographic review that is discussed in this article. Initially, the presence of the theme of food and nutrition was assessed in studies in the social sciences, by focusing on the approaches related to dietary modernity, especially as found in the works of Claude Fischler. The main subjects of discussion were related to food and nutrition and changes in the work environment, the expansion of commerce, the feminization of society and the question of identity. By understanding the food phenomenon and consumption thereof using a more qualitative approach, it is possible to make progress in configuring the nutritional sciences, adopting a comprehensive approach to food and nutrition in this day and age. Future studies should be dedicated to investigating food consumption as a social phenomenon in order to aggregate new analytical components with a biomedical emphasis to the body of results.

    The use of modern chemotherapy (CT) allowed to achieve significant progress in the treatment of many malignant tumors that were previously considered fatal. Improving the efficiency of the treatment was achieved by the intensification of chemotherapy. However, intensification of chemotherapy regimes provoked increase in the number of side effects of anticancer therapy,which often lead to a decrease in the intensity of the selected mode, the additional financial costs of treating the complications and the formation of the negative attitude of the patient to treatment. Thus, the side effects of chemotherapy are the actual problem of modern oncology. The purpose of this literature review was to investigate the frequency, symptoms and ways to prevent and treat various types of toxicity of chemotherapy.

  19. A Ffowcs Williams and Hawkings formulation for hydroacoustic analysis of propeller sheet cavitation

    Testa, C.; Ianniello, S.; Salvatore, F.

    2018-01-01

    A novel hydroacoustic formulation for the prediction of tonal noise emitted by marine propellers in presence of unsteady sheet cavitation, is presented. The approach is based on the standard Ffowcs Williams and Hawkings equation and the use of transpiration (velocity and acceleration) terms, accounting for the time evolution of the vapour cavity attached on the blade surface. Drawbacks and potentialities of the method are tested on a marine propeller operating in a nonhomogeneous onset flow, by exploiting the hydrodynamic data from a potential-based panel method equipped with a sheet cavitation model and comparing the noise predictions with those carried out by an alternative numerical approach, documented in literature. It is shown that the proposed formulation yields a one-to-one correlation between emitted noise and sheet cavitation dynamics, carrying out accurate predictions in terms of noise magnitude and directivity.

    Development of a novel delivery system has been attempted to deliver viable probiotic cells into the gut for a prolonged period of time while maintaining high numbers of viable cells within the formulation throughout the shelf-life of the product and during the gastrointestinal transit. Core mucoadhesive microspheres of Bacillus coagulans were developed employing several grades of hypromellose, a mucoadhesive polymer, following coacervation and phase separation technique and were subsequently enteric-coated with hypromellose phthalate. Microspheres were evaluated for percent yield; entrapment efficiency; in vitro swelling; surface morphology; particle size, size distribution, and zeta potential; flow property, mucoadhesion property by the ex vivo mucoadhesive strength test and the in vitro wash off test; in vitro release profile and release kinetic; in vivo probiotic activity; and stability. The values for the kinetic constant and regression coefficient of model-dependent approaches and the difference factor (f(1)), the similarity factor (f(2)), and the Rescigno index (ξ(1) and ξ(2)) of model independent approaches were determined for comparing in vitro dissolution profiles. Freeze dried B. coagulans cells were successfully formulated as enteric-coated mucoadhesive microspheres with satisfactory physical structure and yield. The viability of B. coagulans was maintained in the simulated gastric conditions and during processing; in simulated intestinal conditions exhibiting mucoadhesion, and controlling and extending the viable cell release following zero-order; and was satisfactorily stable at room temperature. Test results depict statistically significant effects of the hypromellose grade and their concentration on the performance and release profile of formulations.

    Recent critical approaches to what has conventionally been described as "scientific" and "technical" knowledge in early modern Europe have provided a wealth of new insights. So far, the various analytical concepts suggested by these studies have not yet been comprehensively discussed. The present essay argues that such comprehensive approaches might prove of special value for long-term and cross-cultural reflections on technology-related knowledge. As heuristic tools, the notions of "formalization" and "interaction" are proposed as part of alternative narratives to those highlighting the emergence of "science" as the most relevant development for technology-related knowledge in early modern Europe.

    Davide Ermacora

    2016-03-01

    Full Text Available A short Hippocratic passage (Epidemiae 5: 86 might constitute the earliest Western surviving variant of the well-known narrative and experiential theme of snakes or other animals getting into the human body (motif B784, tale-type ATU 285B*. This paper aims: 1 to throw light on this ancient passage through a comparative folkloric analysis and through a philological-contextual study, with reference to modern and contemporary interpretations; and 2 to offer an examination of previous scholarly enquiries on the fantastic intrusion of animals into the human body. In medieval and post-medieval folklore and medicine, sleeping out in the field was dangerous: snakes and similar animals could, it was believed, crawl into the sleeper’s body through the ears, eyes, mouth, nostrils, anus and vagina. Comparative material demonstrates, meanwhile, that the thirsty snake often entered the sleeper’s mouth because of its love of milk and wine. I will argue that while Epidemiae 5: 86 is modelled on this long-standing legendary pattern, for which many interesting literary pre-modern (and modern parallels exist, its relatively precise historical and cultural framework can be efficiently analysed. The story is embedded in a broad set of Graeco-Roman ideas and practices surrounding ancient beliefs about snakes and attitudes to the drinking of unmixed wine.

  8. International safeguards for a modern MOX [mixed-oxide] fuel fabrication facility

    1987-03-01

    Bulk-handling facilities that process plutonium for commercial fuel cycles offer considerable challenges to nuclear materials safeguards. Modern fuel fabrication facilities that handle mixed oxides of plutonium and uranium (MOX) often have large inventories of special nuclear materials in their process lines and in storage areas for feed and product materials. In addition, the remote automated processing prevalent at new MOX facilities, which is necessary to minimize radiation exposures to personnel, tends to limit access for measurements and inspections. The facility design considered in this study incorporates all these features as well as state-of-the-art measurement technologies for materials accounting. Key elements of International Atomic Energy Agency (IAEA) safeguards for such a fuel-cycle facility have been identified in this report, and several issues of primary importance to materials accountancy and IAEA verifications have been examined. We have calculated detection sensitivities for abrupt and protracted diversions of plutonium assuming a single materials balance area for all processing areas. To help achieve optimal use of limited IAEA inspection resources, we have calculated sampling plans for attributes/variables verification. In addition, we have demonstrated the usefulness of calculating σ/sub (MUF-D)/ and detection probabilities corresponding to specified material-loss scenarios and resource allocations. The data developed and the analyses performed during this study can assist both the facility operator and the IAEA in formulating necessary safeguards approaches and verification procedures to implement international safeguards for special nuclear materials

In addition, the remote automated processing prevalent at new MOX facilities, which is necessary to minimize radiation exposures to personnel, tends to limit access for measurements and inspections. The facility design considered in this study incorporates all these features as well as state-of-the-art measurement technologies for materials accounting. Key elements of International Atomic Energy Agency (IAEA) safeguards for such a fuel-cycle facility have been identified in this report, and several issues of primary importance to materials accountancy and IAEA verifications have been examined. We have calculated detection sensitivities for abrupt and protracted diversions of plutonium assuming a single materials balance area for all processing areas. To help achieve optimal use of limited IAEA inspection resources, we have calculated sampling plans for attributes/variables verification. In addition, we have demonstrated the usefulness of calculating sigma/sub (MUF-D)/ and detection probabilities corresponding to specified material-loss scenarios and resource allocations. The data developed and the analyses performed during this study can assist both the facility operator and the IAEA in formulating necessary safeguards approaches and verification procedures to implement international safeguards for special nuclear materials.

    With the adoption of the Kyoto Protocol in 1997 national leaders have started investigating options for reducing carbon emissions within national borders. Despite confronting similar energy issues, every country that adopted the Kyoto Protocol has a unique energy strategy - being characterized by a different context, social, economic or environmental that influences the way different nations deal with climate change and other energy-related issues. Finding that currently available energy models are often too detailed or narrowly focused to inform longer-term policy formulation and evaluation holistically, the present study proposes the utilization of an integrated cross-sectoral medium to longer-term research and modeling approach, incorporating various methodologies to minimize exogenous assumptions and endogenously represent the key drivers of the system analyzed. The framework proposed includes feedback, delays and non-linearity and focuses on structure, scenarios and policies, requires a profound customization of the model that goes beyond a new parameterization. The inclusion of social and environmental factors, in addition to economic ones, all unique to the geographical area analyzed, allows for a wider analysis of the implication of policies by identifying potential side effect or longer-term bottlenecks for socio-economic development and environmental preservation arising from cross-sectoral relations.

    Though Malaysia has no nuclear power station, but the management of its low level radioactive waste generated from industrial activities involves most of the same issues that must be considered in countries with nuclear power. These include public consultation at all stages, an open approach, high level scientific and engineering input and political decision by the Government. A carefully planned approach, which involves the public and gives time to build trust and confidence, is necessary for success. It is also pertinent to establish accurate and reliable data on environmental radiation to accurately assess possible risk. This is where a national monitoring program on environmental radiation is very important. While accurate data will help formulate sound policy on radioactive waste management, it should also be readily available to the public to gain support and acceptance. This paper presents arguments on the importance of a national monitoring program for environmental radiation as an input for formulating a policy on radioactive waste management in Malaysia.

  13. A hybrid formulation for the numerical simulation of condensed phase explosives

    Science.gov (United States)

    Michael, L.; Nikiforakis, N.

    2016-07-01

    In this article we present a new formulation and an associated numerical algorithm, for the simulation of combustion and transition to detonation of condensed-phase commercial- and military-grade explosives, which are confined by (or in general interacting with one or more) compliant inert materials. Examples include confined rate-stick problems and interaction of shock waves with gas cavities or solid particles in explosives. This formulation is based on an augmented Euler approach to account for the mixture of the explosive and its products, and a multi-phase diffuse interface approach to solve for the immiscible interaction between the mixture and the inert materials, so it is in essence a hybrid (augmented Euler and multi-phase) model. As such, it has many of the desirable features of the two approaches and, critically for our applications of interest, it provides the accurate recovery of temperature fields across all components. Moreover, it conveys a lot more physical information than augmented Euler, without the complexity of full multi-phase Baer-Nunziato-type models or the lack of robustness of augmented Euler models in the presence of more than two components. The model can sustain large density differences across material interfaces without the presence of spurious oscillations in velocity and pressure, and it can accommodate realistic equations of state and arbitrary (pressure- or temperature-based) reaction-rate laws. Under certain conditions, we show that the formulation reduces to well-known augmented Euler or multi-phase models, which have been extensively validated and used in practice. The full hybrid model and its reduced forms are validated against problems with exact (or independently-verified numerical) solutions and evaluated for robustness for rate-stick and shock-induced cavity collapse case-studies.

    The I and C modernization activities are motivated with the next aspects. Demand on new functionalities not included in the original design; Reduction of operation and maintenance cost; Increasing of safety requirements; Gradual disappearing of the technical support of the manufacturers; Demand on higher quality of the equipment. Since plant will reach the half of his lifetime within few years, a peak of modernization activities is planned providing the stable operation till end of the lifetime. It concerns not only the I and C but other systems as well. By the strategy the modernization has to be finished within about ten years. There is a long term and a middle term reconstruction plan for I and C systems. The long term plan defines a systematic approach of modernization. The realization of the particular projects must not exceed the period of yearly outages. The middle term plan defines the approved activities and contains allocated resources to them. The modernization activities could be divided on two groups: a) Reconstruction of existing systems or construction of new ones; b) Systematic, 'pin-to-pin replacement' of certain kind of equipment belonging to different I and C systems leaving the functions and the architecture unchanged.

    2012-11-01

    Full Text Available While there are several techniques for analyzing the impact of claims on time schedule and productivity,very few are considered adequate and comprehensive to consider risks and uncertainties.A generic approach for claims analysis using simulation is proposed. The formulation of the generic methodology presented in this paper depends on three simulation models;As-Planned Model (APM,As-Built Model (ABM, and What-Would-HaveBeenModel(WWHBM. The proposed generic methodology as presented in this paper provides a good basis as a more elaborate approach to better analyze claims and their impacts on project time and productivity utilizing discrete event simulation.The approach proposed allows for scenario analysis to account for the disputed events and workflow disruptions. The proposed models will assist claimants in presenting their cases effectively and professionally.

    2015-06-01

    Full Text Available This paper, following the approach of the Dutch scholars de Vries and vab der Woude, claims that the Netherlands, rather than England (as it is generally assumed, were the first country, which performed the transition from the traditional society to modern one. Identification of criteria distinguishing traditional and modern societies follows the works of W. Rostow, S. Kuznets and other authors who studied the issue. In order to prove the thesis, author compares urbanization level in Holland and in England, as well as degree of commercialization of those economies, and considers the process of commercial and productive specialization in the United Provinces. Besides that, the formation of modern-type institutional system in Holland is analyzed: the genesis of the markets of factors of production, development of monetary and credit systems and of institutional and technological basis of the industry, strengthening of competitive forces in the economy. Land ownership structure in Holland is considered and its role in genesis of the markets of factors of production. Attention is paid to technological basis of the industry, examined is the impact of immigration. It concludes that the Netherlands were the first country where modern economic growth, as defined by S. Kuznets, started. It was Holland where for the first time the markets of factors of production were formed and, what is particularly important, the industry began to operate on a competitive basis.

    The article deals with issues of technical and economic substantiation of priorities and scopes of modernizing the existing thermal power plants (TPPs) in Russia to work out long-term forecasts of the development of the industry. The current situation in the TPP modernization trends is analyzed. The updated initial figures of the capital and operation costs are presented and the obtained estimates of the comparative efficiency of various investment decisions on modernization and equipment replacement at gas-and-oil-burning and coal-fired TPPs with regard to the main zones of the national Unified Power System (UPS) of Russia are cited. The results of optimization of the generating capacity structure underlie a study of alternative TPP modernization strategies that differ in the scope of switching to new technologies, capital intensity, and energy efficiency (decrease in the average heat rate). To provide an integral economic assessment of the above strategies, the authors modified the traditional approach based on determination of the overall discounted costs of power supply (least-cost planning) supplemented with a comparison by the weighted average wholesale price of the electricity. A method for prediction of the wholesale price is proposed reasoning from the direct and dual solutions of the optimization problem. The method can be adapted to various combinations of the mechanisms of payment for the electricity and the capacity on the basis of marginal and average costs. Energy and economic analysis showed that the opposite effects of reduction in the capital investment and fuel saving change in a nonlinear way as the scope of the switch to more advanced power generation technologies at the TPPs increases. As a consequence, a strategy for modernization of the existing power plants rational with respect to total costs of the power supply and wholesale electricity prices has been formulated. The strategy combines decisions on upgrade and replacement of the equipment

    1983-01-01

    A time-dependent formulation of the boomerang model for resonant electron--molecule scattering is presented in terms of a wave packet propagating on the complex potential surface of the metastable anion. The results of calculations using efficient semiclassical techniques for propagating the wave packet are found to be in excellent agreement with full quantum-mechanical calculations of vibrational excitation cross sections in e - --N 2 scattering. The application of the wave packet formulation as a computational and conceptual approach to the problem of resonant collisions with polyatomic molecules is discussed in the light of recent wave packet calculations on polyatomic photodissociation and Raman spectra

    2015-02-01

    Full Text Available The history of modern Chinese Buddhism has begun to attract attention in recent years. Some scholars have done inspiring research as they unravel the integration of Buddhism into the highly secularized process of Chinese modernity by drawing on the repository of knowledge on modern China. While this special issue joins this exciting endeavor, it also uses Buddhism as a window to reflect on scholarship on Chinese modernity. Conceptually, this special issue presses scholars in the field of modern China to rethink the place of tradition in the course of modernity. Thematically we show the expansionist impulse of Chinese Buddhism: In addition to envisioning the geographical expansion of their religion, Chinese Buddhists have endeavored to enhance the significance of Buddhism in various dimensions of Chinese society in particular and human life in general.

    Karwan Fatah-Black

    2013-03-01

    Full Text Available This article considers what the migration circuits to and from Suriname can tell us about Dutch early modern colonisation in the Atlantic world. Did the Dutch have an Atlantic empire that can be studied by treating it as an integrated space, as suggested by New Imperial Historians, or did colonisation rely on circuits outside Dutch control, stretching beyond its imperial space? An empire-centred approach has dominated the study of Suriname’s history and has largely glossed over the routes taken by European migrants to and from the colony. When the empirecentred perspective is transcended it becomes possible to see that colonists arrived in Suriname from a range of different places around the Atlantic and the European hinterland. The article takes an Atlantic or global perspective to demonstrate the choices available to colonists and the networks through which they moved.

  4. A quasi-linear formulation for chemically reacting compressible mixtures of imperfect gases

    Lentini, D.

    2008-01-01

    A quasi-linear formulation is proposed for high-speed finite-rate chemically reacting mixtures of imperfect gases, i.e., thermally perfect gases with specific heat varying with temperature. It retains the same formalism of a well-tried counterpart formulation for perfect gases, which has been proven to be suited for application of accurate and fast algorithms. Equations for both quasi-monodimensional flows, and for axisymmetric viscous flows are presented. The approach is based on the definition of an appropriate function F of temperature and concentration, which allows to identify Riemann variables for the flow under consideration; the formulation also includes equations for the entropy and the mass fractions of the N chemical species present in the reacting mixture. The key function F must be computed by numerical quadrature, together with its derivatives with respect to the individual species mass fractions. An example of computation of these quantities is reported, with reference to conditions in the combustion chamber of the Vulcain engine powering the first stage of the Ariane 5 launcher. Such a computation is demonstrated to be both economic and accurate, thus proving the workability of the proposed approach. Further, an estimate of the variation of the mixture specific heat ratio with temperature is given, in order to underline the importance of the effect under consideration.

  5. An extension of implicit Monte Carlo diffusion: Multigroup and the difference formulation

    2010-01-01

    Implicit Monte Carlo (IMC) and Implicit Monte Carlo Diffusion (IMD) are approaches to the numerical solution of the equations of radiative transfer. IMD was previously derived and numerically tested on grey, or frequency-integrated problems . In this research, we extend Implicit Monte Carlo Diffusion (IMD) to account for frequency dependence, and we implement the difference formulation as a source manipulation variance reduction technique. We derive the relevant probability distributions and present the frequency dependent IMD algorithm, with and without the difference formulation. The IMD code with and without the difference formulation was tested using both grey and frequency dependent benchmark problems. The Su and Olson semi-analytic Marshak wave benchmark was used to demonstrate the validity of the code for grey problems . The Su and Olson semi-analytic picket fence benchmark was used for the frequency dependent problems . The frequency dependent IMD algorithm reproduces the results of both Su and Olson benchmark problems. Frequency group refinement studies indicate that the computational cost of refining the group structure is likely less than that of group refinement in deterministic solutions of the radiation diffusion methods. Our results show that applying the difference formulation to the IMD algorithm can result in an overall increase in the figure of merit for frequency dependent problems. However, the creation of negatively weighted particles from the difference formulation can cause significant numerical instabilities in regions of the problem with sharp spatial gradients in the solution. An adaptive implementation of the difference formulation may be necessary to focus its use in regions that are at or near thermal equilibrium.

    Quality by design (QbD) is an essential part of the modern approach to pharmaceutical quality. This study was conducted in the framework of a QbD project involving ramipril tablets. Preliminary work included identification of the critical quality attributes (CQAs) and critical process parameters (CPPs) based on the quality target product profiles (QTPPs) using the historical data and risk assessment method failure mode and effect analysis (FMEA). Compendial and in-house specifications were selected as QTPPs for ramipril tablets. CPPs that affected the product and process were used to establish an experimental design. The results thus obtained can be used to facilitate definition of the design space using tools such as design of experiments (DoE), the response surface method (RSM) and artificial neural networks (ANNs). The project was aimed at discovering hidden knowledge associated with the manufacture of ramipril tablets using a range of artificial intelligence-based software, with the intention of establishing a multi-dimensional design space that ensures consistent product quality. At the end of the study, a design space was developed based on the study data and specifications, and a new formulation was optimized. On the basis of this formulation, a new laboratory batch formulation was prepared and tested. It was confirmed that the explored formulation was within the design space.

    2010-01-01

    The potential of Ayurvedic philosophy and medicines needs to be recognized and converted into real life treatment paradigm. This article describes a comprehensive therapeutic approach used in Ayurveda and modern medicine to treat arthritis. We present concise summary of various controlled drug trials carried out by us to validate standardized Ayurvedic drugs using modern medicine protocol to treat Rheumatoid Arthritis and Osteoarthritis knees. Several of the latter are published. The trials consistently demonstrate excellent safety of Ayurvedic medicines but often fail to unequivocally show superior efficacy. Some key findings of a recently unpublished trial in OA knees are also presented to show equivalence between Ayurvedic medicine and celecoxib and glucosamine, and we speculate that equivalence trials may be a way forward. The data from the trials also supports the Ayurvedic ‘Rasayana’ concept of immune-modulation and healing. We need to interpret logic of Ayurveda when, adopting modern science tools in drug development and validation and much research is required. Validation of Ayurvedic medicines using the latter approach may lead to an evidence based Ayurveda – Modern Medicine interface. Also, in pursuit of finding better treatment solutions, we ought to step beyond the realm of only drugs and attempt validation of comprehensive specific treatment package as per classical Ayurveda. Finally, validation of a combined (Ayurveda and modern medicine) therapeutic approach with superior efficacy and safety is likely to be a major leap in overcoming some of the current frustrations to treat difficult disorders like arthritis using only modern medicines.

    The tactile perception is essential for all types of topical formulations (cosmetic, pharmaceutical, medical device) and the possibility to predict the sensorial response by using instrumental methods instead of sensory testing would save time and cost at an early stage product development. Here, we report on an instrumental evaluation method using tactile friction measurements to estimate perceptual attributes of topical formulations. Friction was measured between an index finger and an artificial skin substrate after application of formulations using a force sensor. Both model formulations of liquid crystalline phase structures with significantly different tactile properties, as well as commercial pharmaceutical moisturizing creams being more tactile-similar, were investigated. Friction coefficients were calculated as the ratio of the friction force to the applied load. The structures of the model formulations and phase transitions as a result of water evaporation were identified using optical microscopy. The friction device could distinguish friction coefficients between the phase structures, as well as the commercial creams after spreading and absorption into the substrate. In addition, phase transitions resulting in alterations in the feel of the formulations could be detected. A correlation was established between skin hydration and friction coefficient, where hydrated skin gave rise to higher friction. Also a link between skin smoothening and finger friction was established for the commercial moisturizing creams, although further investigations are needed to analyse this and correlations with other sensorial attributes in more detail. The present investigation shows that tactile friction measurements have potential as an alternative or complement in the evaluation of perception of topical formulations. © 2015 John Wiley & Sons A/S.

  11. Milestones of the history of modern Western theory of migration

    A M Adediran

    2015-12-01

    Full Text Available The article outlines the key stages in the development of modern theory of migration following the historical sequence and continuity of its basic conceptual constructs’ formation. Although the author refers to the twentieth century as a chronological framework of the text, the narrative begins from the works of E. Ravenstein published at the end of the XIX century, for they laid the foundation for future theoretical studies on migration issues. In particular, many well-known scientists still use concepts “laws of migration” and “attracting and push factors of migration” proposed by Ravenstein claiming their timeless validity or, on the contrary, criticizing them for the loss of relevance in the new social and cultural realities. The author considers as milestones of the modern theory of migration the works of the representatives of Chicago school of sociology that enriched the conceptual apparatus of the analysis of migration processes and the typology of driving causes of migration; the works of S. Stouffer, G. Zipf, E. Lee and W. Lewis, W. Zelinsky and D. Massey. Finally, the article summarizes the objective trends in today’s global development that force scientists to introduce new accents in the study of migration processes, although upon closer inspection it turns out that all “new” ideas had already been formulated in early migration studies and just got a new sound in another historical period.

    As a case study of patent coverage for a repurposed drug, Biogen Idec's approach for Tecfidera(®), an oral formulation of dimethyl fumarate, was analyzed. While mixtures of fumarates have been used for over 50 years to treat psoriasis, Tecifidera is approved for the treatment of relapsing-remitting multiple sclerosis. Biogen pursued claims to pharmaceutical formulations and useful doses for treating multiple sclerosis, an approach that is relevant to pharmaceutical lifecycle management in general. A survey of recent US, EP, and PCT patent applications indicate other companies are developing competing fumarate formulations. While it is possible to pursue secondary patents for compounds without composition of matter coverage, regulatory data exclusivity provides additional protection to delay competitors.

    Full Text Available In the article, the need of transition to the rational subsoil use (the alternative mining approach is proved, which unlike general one supposes the increasing of extraction rate of valuable components in the deposit and multiple use of raw materials, the maximizing recycling, the decreasing of land occupation, the increasing of the development period of deposit at some income decrease up to the moderate level, which is enough to provide the attraction for investors. The multicriteriality is considered as the crucial principle of rational subsoil use at taking management decisions, i.e. the considering of ecological, economic and social targets, aimed at receiving moderate profit at proper social and environmental standards. The graphic representation of models of the general mining approach and the alternative one allows to emphasize the specified advantages of transition to rational subsoil resources development and reflect them in design equation. In the paper, three performance strategies providing the implementation of the alternative approach are offered: full-field development, application ecologically and economically effective systems and the development processes, consideration of reclamation and minimization of long term environmental effects of mining

    To characterize the surface properties of some modern resin composites employing a series of physicochemical methods. Specimens from three microhybrid (Palfique Estellite-PE, Z250 Filtek-ZF, Tetric Ceram-TC) and one nanofilled (Supreme Filtek-SF) conventionally photo-cured resin composites polished with Soflex disks were studied for the following properties: Surface chemical composition and degree of C=C conversion (FTIR), surface energetics (contact angles), surface texture (AFM), surface roughness (AFM, stylus profilometry) and gloss (60 degrees-, 20 degrees-angle specular gloss). Polar and non polar molecular groups were identified in all products including NH and CONH (SF, ZF, TC). SF and ZF demonstrated higher conversion than PE and TC (P 0.05) were found in critical surface tension, total work of adhesion and its polar and dispersion components, the latter being the highest in all products. AFM showed the smoothest surface texture in PE. The ranking of Sa, Sq, Ra and Rz roughness parameters was PEgloss measurements (PE, SF>ZF>TC, PTC, Pgloss differences. A positive correlation was found between Sa and Ra and a negative one between Sa and 20 degree-angle gloss.

    Full Text Available The question whether freedom of religion requires permitting the slaughter of animals in accordance with Islamic rites – a question which was the subject of a decision by the German Federal Constitutional Court in 2002 –is an example of the general problem how the law and the constitution of a modern, secular society can deal with the Sharia, a theonomous law which claims authority by divine revelation. The genetic links between western christianity and the development of the foundations of modern society in Europe do not provide evidence of the incompatibility of Islam and modernity. But they do emphasize that the tensions resulting from the immigration of 3 million muslims in Germany are a great challenge for the constitutional order. A modern constitution of the Western European and North-Atlantic type, such as the german constitution (Grundgesetz, does not allow the dissolution of the tensions between secular law and individual religious autonomy unilaterally in favour of the secular law. This kind of tension is by no means unknown in modern society. Functional differentiation and individualization are core characteristics of modern society. But in view of the challenge by Islam and other challenges, such as ecological problems, we can ask if the »experiment in modernity«, the project of the Enlightenment, is destined to fail because of the dissonance and the lack of understanding between the partial systems of the society. This question is the starting point to outline evolutionary processes of integration in modern society. In this context the constitution proves to be an important tool of integration. Controversies about the scope of validity claimed by the partial systems are matters of constitutional law. The modern constitution is a specific form in which modern society describes itself as a unity insuring »practical concordance« between colliding freedoms and claims of validity. In the conflict of modern ethical principles of

    A conceptual framework for accident occurrence is developed based on the principle of the driver as an information processor. The framework underlies the development of a modeling approach that is consistent with the definition of exposure to risk as a repeated trial. Survival theory is proposed as a statistical technique that is consistent with the conceptual structure and allows the exploration of a wide range of factors that contribute to highway operating risk. This survival model of accident occurrence is developed at a disaggregate level, allowing safety researchers to broaden the scope of studies which may be limited by the use of traditional aggregate approaches. An application of the approach to motor carrier safety is discussed as are potential applications to a variety of transportation industries. Lastly, a typology of highway safety research methodologies is developed to compare the properties of four safety methodologies: laboratory experiments, on-the-road studies, multidisciplinary accident investigations, and correlational studies. The survival theory formulation has a mathematical structure that is compatible with each safety methodology, so it may facilitate the integration of findings across methodologies.

    Using Eudragit® E PO (EudrE) as a polymethacrylate carrier, the aim of the study was to develop a pH-independent dosage form containing ibuprofen (IBP) as an active compound via chemical modification of the polymer (i.e. quaternization of amine function) or via the addition of dicarboxylic acids (succinic, glutaric and adipic acid) to create a pH micro-environment during dissolution. Biconvex tablets (diameter: 10 mm; height: 5 mm) were produced via hot melt extrusion and injection molding. In vitro dissolution experiments revealed that a minimum of 25% of quaternization was sufficient to partially (up to pH 5) eliminate the pH-dependent effect of the EudrE/IBP formulation. The addition of dicarboxylic acids did not alter IBP release in a pH 1 and 3 medium as the dimethyl amino groups of EudrE are already fully protonated, while in a pH 5 solvent IBP release was significantly improved (cf. from 0% to 92% release after 1 h dissolution experiments upon the addition of 20 wt.% succinic acid). Hence, both approaches resulted in a pH-independent (up to pH 5) immediate release formulation. However, the presence of a positively charged polymer induced stability issues (recrystallization of API) and the formulations containing dicarboxylic acids were classified as mechanically unstable. Hence, further research is needed to obtain a pH-independent immediate release formulation while using EudrE as a polmethacrylate carrier.
