    DELTA Diesel Engine Light Truck Application End of Contract Report DE-FC05-97-OR22606 EXECUTIVE SUMMARY This report is the final technical report of the Diesel Engine Light Truck Application (DELTA) program under contract DE-FC05-97-OR22606. During the course of this contract, Detroit Diesel Corporation analyzed, designed, tooled, developed and applied the ''Proof of Concept'' (Generation 0) 4.0L V-6 DELTA engine and designed the successor ''Production Technology Demonstration'' (Generation 1) 4.0L V-6 DELTA engine. The objectives of DELTA Program contract DE-FC05-97-OR22606 were to: Demonstrate production-viable diesel engine technologies, specifically intended for the North American LDT and SUV markets; Demonstrate emissions compliance with significant fuel economy advantages. With a clean sheet design, DDC produced the DELTA engine concept promising the following attributes: 30-50% improved fuel economy; Low cost; Good durability and reliability; Acceptable noise, vibration and harshness (NVH); State-of-the-art features; Even firing, 4 valves per cylinder; High pressure common rail fuel system; Electronically controlled; Turbocharged, intercooled, cooled EGR; Extremely low emissions via CLEAN Combustion{copyright} technology. To demonstrate the engine technology in the SUV market, DDC repowered a 1999 Dodge Durango with the DELTA Generation 0 engine. Fuel economy improvements were approximately 50% better than the gasoline engine replaced in the vehicle.

    The Diesel Engine Light Truck Application (DELTA) program consists of two major contracts with the Department of Energy (DOE). The first one under DE-FC05-97-OR22606, starting from 1997, was completed in 2001, and consequently, a final report was submitted to DOE in 2003. The second part of the contract was under DE-FC05-02OR22909, covering the program progress from 2002 to 2007. This report is the final report of the second part of the program under contract DE-FC05-02OR22909. During the course of this contract, the program work scope and objectives were significantly changed. From 2002 to 2004, the DELTA program continued working on light-duty engine development with the 4.0L V6 DELTA engine, following the accomplishments made from the first part of the program under DE-FC05-97-OR22606. The program work scope in 2005-2007 was changed to the Diesel Particulate Filter (DPF) soot layer characterization and substrate material assessment. This final report will cover two major technical tasks. (1) Continuation of the DELTA engine development to demonstrate production-viable diesel engine technologies and to demonstrate emissions compliance with significant fuel economy advantages, covering progress made from 2002 to 2004. (2) DPF soot layer characterization and substrate material assessment from 2005-2007.

    Full Text Available The purpose of this paper is to analyse the legislation, doctrinal opinions and relevant case law regarding the rules of jurisdiction applicable to the cases arising from contracts concluded by electronic means (e-contracts.Considering the elements of foreign origin that often affect this type of contracts, and the lack of a global agreement regarding international jurisdiction and recognition and enforcement of judgements, the objectives pursued by the author are:- identification of rules of jurisdiction applicable to the cases arising from e-contracts,- identification of problems that could arise from law’s interpretation,- issuing of the de lege ferenda proposals.At European Union level, according to the provisions of Brussels I Regulation, as a general rule, actions against a person domiciled in a Member State shall be brought to the courts of that State.According to the same Regulation, cases resulting from a contractual relationship may be decided by the courts of the place of performance of the contractual obligation. In lack of specific jurisdictional rules, the above rules apply to B2B e-contracts. In the case of B2C e-contracts, the consumer can bring proceedings either before the courts of the Member State of his domicile or before the courts of the Member State of the defendant’s domicile. The consumer can only be sued in the Member State of his domicile. The rules protecting the consumer apply if the trader ‘directs its activities’ to the Member State in which the consumer is domiciled. If the defendant is not domiciled in a Member State, the international jurisdiction is determined, in each Member State, according to its national rules of international private laws.

    Iskandar, B. P.; Husniah, H.

    2016-02-01

    This paper deals with the application of copula in maintenance contracts for a nonrepayable item. Failures of the item are modeled using a two dimensional approach where age and usage of the item and this requires a bi-variate distribution to modelling failures. When the item fails then corrective maintenance (CM) is minimally repaired. CM can be outsourced to an external agent or done in house. The decision problem for the owner is to find the maximum total profit whilst for the agent is to determine the optimal price of the contract. We obtain the mathematical models of the decision problems for the owner as well as the agent using a Nash game theory formulation.

Also by the help of weak $P$-property and $P$-property, we proved existence and uniqueness of best proximity point. There is a simple example to show the validity of our results. Our results extended and unify many existing results in the literature. Moreover, an application to fractional order functional differential equation is discussed.

  12. Combined application of neuromuscular electrical stimulation and voluntary muscular contractions.

    Science.gov (United States)

    Paillard, Thierry

    2008-01-01

    Electromyostimulation (EMS) and voluntary muscle contraction (VC) constitute different modes of muscle activation and induce different acute physiological effects on the neuromuscular system. Long-term application of each mode of muscle activation can produce different muscle adaptations. It seems theoretically possible to completely or partially cumulate the muscle adaptations induced by each mode of muscle activation applied separately. This work consisted of examining the literature concerning the muscle adaptations induced by long-term application of the combined technique (CT) [i.e. EMS is combined with VC - non-simultaneously] compared with VC and/or EMS alone in healthy subjects and/or athletes and in post-operative knee-injured subjects. In general, CT induced greater muscular adaptations than VC whether in sports training or rehabilitation. This efficiency would be due to the fact that CT can facilitate cumulative effects of training completely or partially induced by VC and EMS practiced alone. CT also provides a greater improvement of the performance of complex dynamic movements than VC. However, EMS cannot improve coordination between different agonistic and antagonistic muscles and thus does not facilitate learning the specific coordination of complex movements. Hence, EMS should be combined with specific sport training to generate neuromuscular adaptations, but also allow the adjustment of motor control during a voluntary movement. Likewise, in a therapeutic context, CT was particularly efficient to accelerate recovery of muscle contractility during a rehabilitation programme. Strength loss and atrophy inherent in a traumatism and/or a surgical operation would be more efficiently compensated with CT than with VC. Furthermore, CT also restored more functional abilities than VC. Finally, in a rehabilitation context, EMS is complementary to voluntary exercise because in the early phase of rehabilitation it elicits a strength increase, which is necessary

  12. The contraction rate in Thompson metric of order-preserving flows on a cone - application to generalized Riccati equations

    CERN Document Server

    Gaubert, Stéphane

    2012-01-01

    We give a formula for the Lipschitz constant in Thompson's part metric of any order-preserving flow on the interior of a (possibly infinite dimensional) closed convex pointed cone. This provides an explicit form of a characterization of Nussbaum concerning non order-preserving flows. As an application of this formula, we show that the flow of the generalized Riccati equation arising in stochastic linear quadratic control is a local contraction on the cone of positive definite matrices and characterize its Lipschitz constant by a matrix inequality. We also show that the same flow is no longer a contraction in other natural Finsler metrics on this cone, including the standard invariant Riemannian metric. This is motivated by a series of contraction properties concerning the standard Riccati equation, established by Bougerol, Liverani, Wojtowski, Lawson, Lee and Lim: we show that some of these properties do, and that some other do not, carry over to the generalized Riccati equation.

  16. Evaluating economic strategies for multi-party application of performance contracting

    Science.gov (United States)

    Zhao, Haiyan

    2007-12-01

    Scope and method of study. This subject matter is focused on the economic justification for energy management projects which involve both an energy client and an energy service company (ESCO) (and possibly other parties) in an Energy Savings Performance Contracting (ESPC) project. In this research, an analysis model is developed which includes multi-party involvement in justifying energy management projects that require expertise and capital beyond that found in the energy client. Examples include energy generation from waste heat, solar applications, and so on. The model is built on a system level and expands risk analysis beyond the simple party views. It is a multi-party model which seeks to find "win-win" solutions for all parties (or to expose shortcomings of projects where all parties cannot "win"). Such model application will help in justifying projects that might otherwise be discarded as too complex and too risky, or expose projects that will not produce demanded economic performance. Findings and conclusions. The inputs of the model are referred to as being probabilistic and deterministic. The outputs of the model are the Net Present Values (NPV) of the client and the ESCO, respectively. The probabilistic inputs are either probability-distributed or simulated with the correlation coefficients from historical data. The deterministic inputs are referred to as either discrete arrays or single values. Multiple scenarios are generated in accordance with the number of the discrete arrays and the number of the values in each array. In each scenario, all probabilistic inputs are simulated, combined with the values randomly picked from the discrete arrays, and entered into the model. The output analysis is based on simulated NPVs for the primary parties (client and ESCO). The major contributions of the research include: (1) develop an analysis protocol for the parties involved in an ESPC project depending on the inputs and outputs of the proposed energy system, (2

    Full Text Available With the economy developing and popular Internet, the general concept of contract signing has changed.In the past, people usually sign a contract at the same time and same place face to face, but actually eachparty involved in contract may live in different part of earth, they want to sign something for business orsome other things in economic, efficient, secure and fairway. A fair contract signing protocol allows twopotentially mis-trusted parities to exchange their commitments (i.e., digital signatures to an agreedcontract over the Internet in a fair way, so that either each of them obtains the other’s signature, orneither party does. Based on the LUCAS signature scheme, a new digital anonymous contract signingprotocol is proposed in this paper. Like the existing LUCAS-based solutions for the same problem, ourprotocol is fair, anonymous and optimistic. Furthermore, the proposed protocol satisfied a newproperty, i.e., it is abuse-free. That is, if the protocol is executed unsuccessfully, either of the two partiescan not show the validity of intermediate results to others.

    2009-09-15

    It is very important to obtain the parameters of deformation size and contraction frequency of women's uterine musculature in medical research. This paper proposes a type of sensor for measuring these parameters and analyzes its force situation. The flexibility of the sensor makes it easy for doctors to let the sensor pass through woman's narrow cervix and get to her uterine cavity. The experiment shows that the sensitivity of three coils in the sample sensor achieves 22.38 nH/mm(2) both for left and right coils, 22.84 nH/mm(2) for top coil, which can meet the requirements of sensitivity for testing the contraction situation of uterine musculature. Furthermore, an interface designed in the back end system can display the parameters of deformation size and vivid contraction situation of women's uterine musculature in real-time. The sensor has been applied in some medical fields.

  19. Fixed points for alpha-psi contractive mappings with an application to quadratic integral equations

    2014-06-01

    Full Text Available Recently, Samet et al [24] introduced the concept of alpha-psi contractive mappings and studied the existence of fixed points for such mappings. In this article, we prove three fixed point theorems for this class of operators in complete metric spaces. Our results extend the results in [24] and well known fixed point theorems due to Banach, Kannan, Chatterjea, Zamfirescu, Berinde, Suzuki, Ciric, Nieto, Lopez, and many others. We prove that alpha-psi contractions unify large classes of contractive type operators, whose fixed points can be obtained by means of the Picard iteration. Finally, we utilize our results to discuss the existence and uniqueness of solutions to a class of quadratic integral equations.

    When active muscles are stretched, our understanding of muscle function is stretched as well. Our understanding of the molecular mechanisms of concentric contraction has advanced considerably since the advent of the sliding filament theory, whereas mechanisms for increased force production during eccentric contraction are only now becoming clearer. Eccentric contractions play an important role in everyday human movements, including mobility, stability, and muscle strength. Shortly after the sliding filament theory of muscle contraction was introduced, there was a reluctant recognition that muscle behaved as if it contained an "elastic" filament. Jean Hanson and Hugh Huxley referred to this structure as the "S-filament," though their concept gained little traction. This additional filament, the giant titin protein, was identified several decades later, and its roles in muscle contraction are still being discovered. Recent research has demonstrated that, like activation of thin filaments by calcium, titin is also activated in muscle sarcomeres by mechanisms only now being elucidated. The mdm mutation in mice appears to prevent activation of titin, and is a promising model system for investigating mechanisms of titin activation. Titin stiffness appears to increase with muscle force production, providing a mechanism that explains two fundamental properties of eccentric contractions: their high force and low energetic cost. The high force and low energy cost of eccentric contractions makes them particularly well suited for athletic training and rehabilitation. Eccentric exercise is commonly prescribed for treatment of a variety of conditions including sarcopenia, osteoporosis, and tendinosis. Use of eccentric exercise in rehabilitation and athletic training has exploded to include treatment for the elderly, as well as muscle and bone density maintenance for astronauts during long-term space travel.

    La theorie des contractions d'algebres de Lie constitue une methode formelle par laquelle sont relies les groupes (algebres) de Lie de differents systemes physiques. Elles consistent en une procedure limite qui implique une relation analogue entre les systemes (ou theories) physiques consideres, et comblent ainsi notre tendance naturelle a unifier notre comprehension de la Nature. Une introduction historique, de meme qu'un bref survol du corps de la these, constituent le premier chapitre. Le chapitre 2 consiste en l'article essentiel de la these: la description des contractions graduees d'algebres de Lie. Cette methode s'applique a toute algebre (ou superalgebre) de Lie de dimension finie ou infinie. La methode associee de contraction de representations n'est pas contenue integralement dans le present texte, mais expliquee brievement dans l'introduction (Chapitre 1), puisque sa formulation originale est due a R. V. Moody et J. Patera. Le chapitre 3 contient un article decrivant un programme developpe pour faire generer et resoudre par ordinateur les equations determinantes des contractions d'algebres de Lie et de leurs representations. Avec le quatrieme chapitre, nous commencons a appliquer a la physique la methode decrite precedemment. Il s'agit d'un article dans mathematique que physique.

    2010-09-01

    Full Text Available In recent years, there has been an explosive growth in the popularity of online social networks such as Facebook. In a new twist, third party developers are now able to create their own web applications which plug into Facebook and work with Facebook's "social" data, enabling the entire Facebook user base of more than 400 million active users to use such applications. These client applications can contain subtle errors that can be hard to debug if they misuse the Facebook API. In this paper we present an experience report on applying Microsoft's new code contract system for the .NET framework to the Facebook API.We wrote contracts for several classes in the Facebook API wrapper which allows Microsoft .NET developers to implement Facebook applications. We evaluated the usefulness of these contracts during implementation of a new Facebook application. Our experience indicates that having code contracts provides a better and quicker software development experience.

  6. New staff contract policy

    2006-01-01

    Following discussion at TREF and on the recommendation of the Finance Committee, Council approved a new staff contract policy, which became effective on 1 January 2006. Its application is covered by a new Administrative Circular No. 2 (Rev. 3) 'Recruitment, appointment and possible developments regarding the contractual position of staff members'. The revised circular replaces the previous Circulars No. 9 (Rev. 3) 'Staff contracts' and No. 2 (Rev. 2) 'Guidelines and procedures concerning recruitment and probation period for staff members'. The main features of the new contract policy are as follows: The new policy provides chances for long-term employment for all staff recruits staying for four years without distinguishing between those assigned to long-term or short-term activities when joining CERN. In addition, it presents a number of simplifications for the award of ICs. There are henceforth only 2 types of contract: Limited Duration (LD) contracts for all recruitment and Indefinite Contracts (IC) for...

    2013-08-01

    The findings of this study indicate that potential exists in non-building applications to save energy and costs. This potential could save billions of federal dollars, reduce reliance on fossil fuels, increase energy independence and security, and reduce greenhouse gas emissions. The Federal Government has nearly twenty years of experience with achieving similar energy cost reductions, and letting the energy costs savings pay for themselves, by applying energy savings performance contracts (ESPC) inits buildings. Currently, the application of ESPCs is limited by statute to federal buildings. This study indicates that ESPCs can be a compatible and effective contracting tool for achieving savings in non-building applications.

    2015-10-01

    In the field of computational biomechanics, the experimental evaluation of the material properties is crucial for the development of computational models that closely reproduce real organ systems. When simulations of muscle tissue are concerned, stress/strain relations for both passive and active behavior are required. These experimental relations usually exhibit certain variability. In this study, a set of material parameters involved in a 3D skeletal muscle model are determined by using a system biology approach in which the parameters are randomly varied leading to a population of models. Using a set of experimental results from an animal model, a subset of the entire population of models was selected. This reduced population predicted the mechanical response within the window of experimental observations. Hence, a range of model parameters, instead of a single set of them, was determined. Rat Tibialis Anterior muscle was selected for this study. Muscles ([Formula: see text]) were activated through the sciatic nerve and during contraction the tissue pulled a weight fixed to the distal tendon (concentric contraction). Three different weights 1, 2 and 3 N were used and the time course of muscle stretch was analyzed obtaining values of (mean [Formula: see text] standard deviation): [Formula: see text], [Formula: see text] and [Formula: see text] respectively. A paired two-sided sign rank test showed significant differences between the muscle response for the three weights ([Formula: see text]). This study shows that the Monte Carlo method could be used for determine muscle characteristic parameters considering the variability of the experimental population.

This includes base load and auxiliary supply, contracts for private, commercial and industrial special customers as well as re-distributors, metering contracts, grid contracts, storage contracts, and biogas and heat supply contracting. The legal problems are outlined clearly and easy to understand, and the following questions are answered: What are the boundary conditions set by the new energy industry law and general civil law? Inhowfar are the contents of contracts influenced by legal specifications? What options are available for contract drafting, and what are their consequences? What contents are of particular importance? What are the requirements that result from price regulation by civil and cartel law? What is the role of licence fees in product design? What are the chances and risks of innovative products? What options for reaction do providers have in case of (impending) customer insolvency? (orig./RHM)

  15. Advice for a career in academic gastroenterology: from fellowship application through job selection and contract negotiations to research and promotion.

    Science.gov (United States)

    Cappell, M S

    2009-03-01

    This study aims to describe a comprehensive strategy for success in academic gastroenterology by reporting common sense, but mostly previously unpublished, recommendations. The recommendation are based on expert opinion from personal experience mentoring 125 gastroenterology fellows and residents as a program director for nine years and from mentoring research while publishing more than 160 articles in peer-reviewed journals and editing 11 books during a 23-year academic career. Primary criteria for fellowship applicant selection include board scores, clinical performance, interview performance, clinical training, and research productivity. For optimal chances, select the subspecialty of gastroenterology early during residency, consult a mentor, and develop a well-planned strategy. Faculty advancement depends upon publications, grants, national recognition, interpersonal skills, and recommendations. Article categories from highest-to-lowest in prestige are original investigations, review articles, book chapters, case reports, and letters/abstracts. Articles are judged by the prestige of the journal of publication. Resubmit rejected articles to successively less prestigious journals until accepted for publication. Articles in journals without peer-review have negligible career impact. Grant support creates protected time. Institutional reputation is important in academics. Do not accept a job without a written contract. Have a lawyer review your contract. An outside offer strengthens a negotiating position. Be sociable and nonconfrontational at work. Network with colleagues. Seek a mentor. Meet your supervisor regularly for feedback. Never express anger at your boss or patients. Avoid litigation with employers. Sub-subspecialize to develop expertise in one area. Focus on this area in your research and clinical practice. In conclusion, a well-planned strategy can help you achieve a senior academic position early and efficiently.

  16. Amending Contracts for Choreographies

    CERN Document Server

    Bocchi, Laura; Tuosto, Emilio; 10.4204/EPTCS.59.10

    2011-01-01

    Distributed interactions can be suitably designed in terms of choreographies. Such abstractions can be thought of as global descriptions of the coordination of several distributed parties. Global assertions define contracts for choreographies by annotating multiparty session types with logical formulae to validate the content of the exchanged messages. The introduction of such constraints is a critical design issue as it may be hard to specify contracts that allow each party to be able to progress without violating the contract. In this paper, we propose three methods that automatically correct inconsistent global assertions. The methods are compared by discussing their applicability and the relationships between the amended global assertions and the original (inconsistent) ones.

    2008-09-01

    Complete details of the thermodynamics and molecular mechanisms of ATP synthesis/hydrolysis and muscle contraction are offered from the standpoint of the torsional mechanism of energy transduction and ATP synthesis and the rotation-uncoiling-tilt (RUT) energy storage mechanism of muscle contraction. The manifold fundamental consequences and mechanistic implications of the unified theory for oxidative phosphorylation and muscle contraction are explained. The consistency of current mechanisms of ATP synthesis and muscle contraction with experiment is assessed, and the novel insights of the unified theory are shown to take us beyond the binding change mechanism, the chemiosmotic theory and the lever arm model. It is shown from first principles how previous theories of ATP synthesis and muscle contraction violate both the first and second laws of thermodynamics, necessitating their revision. It is concluded that the new paradigm, ten years after making its first appearance, is now perfectly poised to replace the older theories. Finally, applications of the unified theory in cell life and cell death are outlined and prospects for future research are explored. While it is impossible to cover each and every specific aspect of the above, an attempt has been made here to address all the pertinent details and what is presented should be sufficient to convince the reader of the novelty, originality, breakthrough nature and power of the unified theory, its manifold fundamental consequences and mechanistic implications, and its applications in health and disease.

  20. Fixed points and chaotic dynamics for expansive-contractive maps in Euclidean spaces, with some applications

    CERN Document Server

    Pireddu, Marina

    2009-01-01

    In this work we introduce a topological method for the search of fixed points and periodic points for continuous maps defined on generalized rectangles in finite dimensional Euclidean spaces. We name our technique "Stretching Along the Paths" method, since we deal with maps that expand the arcs along one direction. Our technique is also significant from a dynamical point of view, as it allows to detect complex dynamics. In particular, we are able to prove semi-conjugacy to the Bernoulli shift and thus positivity of the topological entropy, the presence of topological transitivity and sensitivity with respect to initial conditions, density of periodic points. Moreover, our approach, although mathematically rigorous, avoids the use of sophisticated topological theories and it is relatively easy to apply to specific models arising in the applications. For example we have here employed the Stretching along the paths method to study discrete and continuous-time models arising from economics and biology.

  5. Can fast-twitch muscle fibres be selectively recruited during lengthening contractions? Review and applications to sport movements.

    Science.gov (United States)

    Chalmers, Gordon R

    2008-01-01

    Literature examining the recruitment order of motor units during lengthening (eccentric) contractions was reviewed to determine if fast-twitch motor units can be active while lower threshold slow-twitch motor units are not active. Studies utilizing surface electromyogram (EMG) amplitude, single motor unit activity, spike amplitude-frequency analyses, EMG power spectrum, mechanomyographic, and phosphocreatine-to-creatine ratio (PCr/Cr) techniques were reviewed. Only single motor unit and PCr/Cr data were found to be suitable to address the goals of this review. Nine of ten single motor unit studies, examining joint movement velocities up to 225 degrees/s and forces up to 53% of a maximum voluntary contraction, found that the size principle of motor unit recruitment applied during lengthening contractions. Deviation from the size principle was demonstrated by one study examining movements within a small range of low velocities and modest forces, although other studies examining similar low forces and lengthening velocities reported size-ordered recruitment. The PCr/Cr data demonstrated the activation of all fibre types in lengthening maximal contractions. Most evidence indicates that for lengthening contractions of a wide range of efforts and speeds, fast-twitch muscle fibres cannot be selectively recruited without activity of the slow-twitch fibres of the same muscle.

    The uterine tetanic contraction and uterine artery blood flow reduction are possible reasons for primary dysmenorrhea (PD). In the present study, we aimed to evaluate the uterine relaxant effect and the influence on uterine artery blood velocity of Ge-Gen Decoction (GGD), a well-known Chinese herbal formula. In female ICR mice, uterine contraction was induced by oxytocin exposure following estradiol benzoate pretreatment, and the uterine artery blood velocity was detected by Doppler ultrasound. Histopathological examination of the uterine tissue samples were performed by H&E staining. Ex vivo studies demonstrated that oxytocin, posterior pituitary, or acetylcholine induced contractions in isolated mouse uterus. GGD inhibited both spontaneous and stimulated contractions. In vivo study demonstrated that GGD significantly reduced oxytocin-induced writhing responses with a maximal inhibition of 87%. Further study demonstrated that GGD normalized oxytocin-induced abnormalities of prostaglandins F2 alpha (PGF2α) and Ca(2+) in mice. In addition, injection of oxytocin induced a decrease in uterine artery blood flow velocity. Pretreatment with GGD reversed the oxytocin response on blood flow velocity. Histopathological examination showed pretreatment with GGD alleviated inflammation and edema in the uterus when compared with the model group. Both ex vivo and in vivo results indicated that GGD possessed a significant spasmolytic effect on uterine tetanic contraction as well as improvement on uterine artery blood velocity which may involve PGF2α and Ca(2+) signaling, suggesting that GGD may have a clinic potential in PD therapy.

    1998-06-01

    This paper explores the wide range of laser micromachining applications used in contract manufacturing. Contract manufacturing is used in several key industries such as microelectronics packaging, semiconductor, data storage, medical devices, communications, peripherals, automobiles and aerospace. Material types includes plastics, metals, ceramics, inorganics and composites. However laser micromachining is just one available technology for micromachining and other methods will be reviewed. Contract manufacturing offers two important glimpses of the future. Firstly prototype work for new applications often beings in contract manufacturing. Secondly, contract manufacturing can be an economic springboard to allow laser systems to be installed in a production environment.

  17. Application of non-state rules in international commercial contracts%论非国内规则在国际商事合同中的适用

    Institute of Scientific and Technical Information of China (English)

    刘益灯; 陈璐

    2015-01-01

    国际商事合同适用非国内规则是国际社会合同准据法发展的重要走势。非国内规则虽然不具有法律约束力,但因其较强的实践操作性而逐渐被各国法院和仲裁机关所适用。在国际商事合同纠纷的解决中,当事人可以协议选择适用国际条约和国际惯例等非国内规则;当事人没有选择时,法院可以依职权主动适用非国内规则。但由于非国内规则本身的局限性、法院地法发展水平的制约以及强行性规范和公共秩序的限制,非国内规则在国际商事合同法律适用中不具有普及性,因此,我国立法机关和司法机关应从完善非国内规则和加强立法及司法两方面入手,推动非国内规则在国际商事合同中的适用。%As the theory of the governing law of contracts is constantly evolving, non-state rules have been applied in international commercial transactions. Non-state rules are not legally binding, but have gradually been adopted by courts and arbitration agencies in many countries owing to their strong practical nature. Non-state rules could be allowed as the applicable law to an international commmerical contract upon the principle of party autonomy or be applied by the judiciary actively. But owing to the limits of the non-state rules themselves, restrictions of the development level of local laws and confinement of the public order, non-state rules can not enjoy popularity in international commercial contracts. Therefore, the legislation and judicial agencies should embark from two aspects to promote the application of non-state rules in international commercial contracts: one is perfecting non-state rules and the other is reinforcing legislation and judiciary laws.

  19. Public works concession. Delimitation from other contracts

    Directory of Open Access Journals (Sweden)

    Cătălina Georgeta MATEI

    2012-12-01

    Full Text Available The concession of public services without the concession of the related public works was viewed as an exception. The public services contract was considered to rank first among the administrative contracts. The European Court of Justice ruled that establishing of the nature of a contract – whether it is a public works contract or a public contract of a different nature – is made by identifying the main purpose of the contract that determines the applicable directive, including situations where the contract has elements regarding the concession of public works as well as other types of public contracts. Also, the concept of concession used in relation to both concession and PPP was deemed in Romania as a source of confusion and ambiguity regarding the confidence of both the public and private partner within the context of project development.

    This paper shall outline the content, application and management strategies for the various contracts related to transport and handling activities. In total, the two sections Logistics and Handling Maintenance are in charge of 27 (!) contracts ranging from small supply contracts to big industrial support contracts. The activities as well as the contracts can generally be divided into four main topics "Vehicle Fleet Management"; "Supply, Installation and Commissioning of Lifting and Hoisting Equipment"; "Equipment Maintenance" and "Industrial Support for Transport and Handling". Each activity and contract requires different approaches and permanent adaptation to the often changing CERN's requirements. In particular, the management and the difficulties experienced with the contracts E072 "Maintenance of lifting and hoisting equipment", F420 "Supply of seven overhead traveling cranes for LHC" and S090/S103 "Industrial support for transport and handling" will be explained in detail.

  5. Contracts in distributed systems

    CERN Document Server

    Bartoletti, Massimo; Zunino, Roberto; 10.4204/EPTCS.59.11

    2011-01-01

    We present a parametric calculus for contract-based computing in distributed systems. By abstracting from the actual contract language, our calculus generalises both the contracts-as-processes and contracts-as-formulae paradigms. The calculus features primitives for advertising contracts, for reaching agreements, and for querying the fulfilment of contracts. Coordination among principals happens via multi-party sessions, which are created once agreements are reached. We present two instances of our calculus, by modelling contracts as (i) processes in a variant of CCS, and (ii) as formulae in a logic. With the help of a few examples, we discuss the primitives of our calculus, as well as some possible variants.

    The application of increasingly stringent heat insulation requirements has led to energy-saving building methods being introduced in recent years. This report discusses the attempts which have been made to manufacture light sand from crushed fine washery refine and pelletized flotation tailings by thermal treatment in a fluidised bed oven. An improvement in thermal resistance was achieved by injecting plastic foam into the chambers of lightweight-concrete cavity building blocks. The compressive strength of the refuse material was tested by the construction of a sound-proof wall. 20 references.

  8. Contracts or Scripts? A Critical Review of the Application of Institutional Theories to the Study of Environmental Change

    Directory of Open Access Journals (Sweden)

    Samy Hotimsky

    2006-06-01

    Full Text Available The impact of new institutionalism on the study of human environment interactions has been meaningful. Institutional perspectives have further shaped and modified the field problems of common pool resources, environmental hazards, and risk and environmental management. Given the relative potential of institutional theories to increase the comprehension of the various dimensions of human-environmental interactions, it has become increasingly important to attempt to consolidate different interpretations of what institutions are, and how they mediate and constrain possibilities for more successful environmental outcomes. This article focuses primarily on contending ontological perspectives on institutions and institutional change. It argues that what should guide the application of institutional theories in practical research regarding environmental change is the ontological dimension, and that the focus of research should be on uncovering the underlying dynamics of institutional change. In doing so, it calls for a methodological pluralism in the investigation of the role institutions play in driving/managing for environmental change.

  14. The distribution contracts: an Iberian approach

    Directory of Open Access Journals (Sweden)

    Sónia de Carvalho

    2016-12-01

    Full Text Available The contracts of commercial distribution are indispensable legal instruments to the development of the economic activity. The distribution, since the industrial revolution, acquired autonomy, given the necessity of specialized intermediation to distribute good and products. In this process, the structural organization of the distribution process suffered mutations, starting to assume a set of activities aiming at adjusting demand to supply, including, among others, clients canvassing, after-sales services, financing and assumption of risks, advisory services, promotion and advertising. The insufficiency of traditional contracts of purchase and sales and commission to satisfy the distributive needs caused by the industrial revolution will justify the development of new contractual schemes, such us agency contract, commercial concession and franchising. The obligation of the distributer to ensure the interests of the producer and to promote the distribution of the goods and services of the producer, in the context of a lasting relation of cooperation between the parts, through which the distributer is incorporated, with greater or minor intensity, in the producer distribution network, allowed us to sustain, as affirmed in the Portuguese and European literature, that distribution contracts could be framed in the same legal category. These contracts, as contracts that were shaped by praxis, do not have, with exception of agency contract, a legal framework in Portugal and Spain. It has been discussed in literature if agency contract legal framework can be applied, by analogy, to the contracts that fit in the legal category of distribution contracts. This paper aims at analyzing the legal framework of contracts of distribution in these legal systems, with the purpose to discuss the analogical application of the agency contract to these contracts.

    2011-01-01

    Vertex deletion and edge deletion problems play a central role in Parameterized Complexity. Examples include classical problems like Feedback Vertex Set, Odd Cycle Transversal, and Chordal Deletion. Interestingly, the study of edge contraction problems of this type from a parameterized perspective has so far been left largely unexplored. We consider two basic edge contraction problems, which we call Path-Contractibility and Tree-Contractibility. Both problems take an undirected graph $G$ and an integer $k$ as input, and the task is to determine whether we can obtain a path or an acyclic graph, respectively, by contracting at most $k$ edges of $G$. Our main contribution is an algorithm with running time $4^{k+O(\\log^2 k)} + n^{O(1)}$ for Path-Contractibility and an algorithm with running time $4.88^k n^{O(1)}$ for Tree-Contractibility, based on a novel application of the color coding technique of Alon, Yuster and Zwick. Furthermore, we show that Path-Contractibility has a kernel with at most $5k+3$ vertices, w...

    The matchmaking service contract is an agreement for setting up, changing or terminating the rights and obligations when the matchmaking service provider introduces the spouse to the client. It has the characteristics of certain personality, the uncertainty of achieving purpose and the formation standard of clauses. Matchmaking service contract is an atypical contract, which is a mixture of intermediation contract and commission contract. At present, with the lack of specific legal provisions in matchmaking service in China, the disputes are greatly increasing about the marriage entrustment cheating, the arbitrary termination of contacts or the return of matchmaking fee. Therefore, it is necessary to apply corresponding legal norm to the resolution of the disputes according to analogizing application principle.%婚介服务合同是指婚介服务提供方为征婚者介绍配偶过程中,双方设立、变更、终止权利义务关系的协议。它具有一定的人身专属性、目的实现的不确定性和条款形成的格式性。婚介服务合同属于无名合同,是一种兼具居间和委托性质的混合合同。目前,由于我国缺乏具体的法律规定,在婚介服务中,婚托、任意解除及服务费用返还等纠纷与日俱增。对此,可以依据“类推适用说”适用相应的法律规范。

  12. Contracts for Abstract Processes in Service Composition

    2011-01-01

    Full Text Available Contracts are a well-established approach for describing and analyzing behavioral aspects of web service compositions. The theory of contracts comes equipped with a notion of compatibility between clients and servers that ensures that every possible interaction between compatible clients and servers will complete successfully. It is generally agreed that real applications often require the ability of exposing just partial descriptions of their behaviors, which are usually known as abstract processes. We propose a formal characterization of abstraction as an extension of the usual symbolic bisimulation and we recover the notion of abstraction in the context of contracts.

  16. Signaling in muscle contraction.

    Science.gov (United States)

    Kuo, Ivana Y; Ehrlich, Barbara E

    2015-02-02

    Signaling pathways regulate contraction of striated (skeletal and cardiac) and smooth muscle. Although these are similar, there are striking differences in the pathways that can be attributed to the distinct functional roles of the different muscle types. Muscles contract in response to depolarization, activation of G-protein-coupled receptors and other stimuli. The actomyosin fibers responsible for contraction require an increase in the cytosolic levels of calcium, which signaling pathways induce by promoting influx from extracellular sources or release from intracellular stores. Rises in cytosolic calcium stimulate numerous downstream calcium-dependent signaling pathways, which can also regulate contraction. Alterations to the signaling pathways that initiate and sustain contraction and relaxation occur as a consequence of exercise and pathophysiological conditions.

    Bryon, P A; Lagarde, M; Dechavanne, M

    1975-12-01

    A stereological model, which provides quantitative information on the morphology of the platelet release reaction as isolated from platelet aggregation, was developed for the human platelets separated from blood by Mustard's procedure. Three morphologically defined spaces (granules, surface-connected canalicular system S.C.S., cytoplasm) were used to characterize platelet degranulation (with the variation of the volume density of the granules) and contraction (with the variation of the volume density of both granules and S.C.S.). This model was applied to the evaluation of ultrastructural changes associated with the thrombin-induced release reaction. Degranulation and contraction were associated in the platelets which had been allowed to release for 1,5 and 150 sec. Under conditions of the study, prostaglandins E1 (10(-7) M) inhibited both degranulation and contraction (p less than 0,001). Aspirin (10(-4) M) only inhibited contraction (p less than 0.01) and dibutyryl-AMPc (10(-4)) only inhibited granulation (p less than 0,001).

  18. Contraction et filamentation des decharges micro-ondes entretenues a la pression atmospherique: Application a la detoxication des gaz a effet de serre

    Science.gov (United States)

    Kabouzi, Yassine

    The remediation of greenhouse gases, such as perfluorinated compounds (PFCs), constitutes a major environmental concern. Plasmas operating at atmospheric pressure offer an efficient technology for the control of toxic and greenhouse gas emission. The two main objectives of the thesis were to investigate the mechanisms of contraction and filamentation in atmospheric-pressure microwave discharges, and to examine their influence on the plasma abatement process of PFC gases in these discharges. The finite thermal conductivity of the gas discharge is responsible for the gas nonuniform heating leading to a contracted discharge column. The gas thermal conductivity and the penetration depth of the microwave electric field in the plasma are shown to set the value of the plasma radius. The degree of contraction and filamentation of microwave discharges can be controlled, and even reduced, by modulating adequately the incident microwave power. The relaxation times of heat conduction and heat release are actually observed to be of the same magnitude, and correspond to the modulation period for which the discharge shows less contraction. PFC molecules are eliminated through their fragmentation by inelastic collisions with electrons and the subsequent oxidation of these fragments. Reformation of PFC molecules is the main process limiting the abatement efficiency in atmospheric-pressure microwave discharges. As a result of discharge radial contraction, a relative "colder" space between the plasma filament and the discharge tube wall favors PFC reformation and, therefore, lowers the destruction efficiency. The PFC destruction efficiency is found to increase with absorbed microwave power. Surface-wave microwave discharges sustained at atmospheric pressure prove to be an efficient and ecological solution for emission reduction of greenhouse gases.

  19. HARMONIZATION OF THE CONSUMER CONTRACT DISPOSITIONS WITH THE GENERAL CONTRACT RULES

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available This work contains and mainly tackles the contract of consumption, its differences and similitudes to a general contract, manners of applying it, and the way in which the former can be better coordinated and correlated to the general contracting terms, established by the civil law. Along the years, the consumption contract has undergone several addenda and it has come to represent an instrument of both refference and regulation for the socio-economical relations between two parties who have a commercial agreement. The general law frame has had a great influence in the development of the consumption contract, as well as on its applicability conditions and its manner of deployment. Through the development of the judicial law concerning the contract of concumption, this type of agreement has influenced, through its human and social nature, both the general contract, and the specific frame it relates to. The relationship between the two types of contract is one of interdependence, which is determined by the need of judicial regulation in the Romanian and European economy. The ceaselees development of interhuman relations pushes society towards maintaining a continuous study of the advancement of specific legislation and judicial regulation. The main purpose of this work is analyzing the general judicial frame and the way in which the differences between the general contract and the consumption one may represent a benefic and mutual influence on protecting the citizens’ rights, which in the case of the consumption contract encompasses the protection of consumers’ rights. Also, it will analyze the aspects that determine the manner of application and the the differences that can be surmounted in order to achieve a better cohesion between these types of contracts.

  20. Capsule contraction syndrome

    Directory of Open Access Journals (Sweden)

    2009-06-01

    Full Text Available Capsule contraction syndrome occurs after fibrous metaplasia of lens proteins that leads to capsular bag contraction. Excessive front capsular wrinkling is seen in capsule contraction syndrome and there is an imbalance between powers supplying capsular integrity. This situation leads to zonular weakness. Capsule contraction syndrome is associated with pseudoexfoliation, older age, uveitis, pars planitis and myotonic muscular dystrophy. In order to decrease the risk of capsule contraction syndrome, front capsulerhexis area should be open as 5.5-6 mm diameter and a curysoft intraocular lens should be used. In order to prevent lens epithelial proliferation and metaplasia, lens epithelial cells at inferior surface of front capsule should be aspirated carefully. If postoperative capsular contraction detected, front capsulotomy should be performed by Nd-YAG laser at postoperative 2 to 3 weeks. In patients that Nd-YAG laser is unsuccessful, capsular tension should be decreased by surgical microincisions. In present study, we evaluated etiology, prevention and management of capsule contraction syndrome in the light of actual literature knowledge.

    The current ST/EL group's installation and maintenance contract expires on June 2001. Official procedures for a new contract began a few months ago. Once the new contract has been adjudicated, contractor firm should establish a Quality Assurance Plan (PAQ) within 6 months to be approved. This PAQ is the essential main instrument which ST/EL group has in order to assure a perfect achievement of signed contract. PAQ efficiency depends on its good knowledge and its permanent application on the part of the contractor firm and especially on the part of ST/EL group. The acquired experience during last PAQ should be reflected in the future contract.

    Takata, S; Takai, H; Ikata, T; Miura, I

    1988-11-30

    The mechanism of muscle fatigue was studied by 31P-MRS. During tetanic contraction for 2 minutes(min), the tension measured with a strain gauge and Phosphocreatine(PCr)/Inorganic phosphate(Pi)+ Phosphomonoester(PME) ratio decreased to 31.5 +/- 4.4% of the control value and 0.6 +/- 0.1, respectively. The intracellular pH(pH) also decreased to 6.62 +/- 0.04. Toward the end of the stimulation, the tension decreased to 25.3 +/- 1.9% of the control value. However, during 20min stimulation, the PCr/(Pi+PME) ratio increased to 2.5 +/- 0.5 and the pH to 6.91 +/- 0.04. These results show that muscular fatigue is ascribable not to a decreased level of high energy metabolites required for actomyosin ATPase, but to an increase in the threshold intensity of excitation in excitation-contraction coupling.

  13. An unsatisfactory contract policy

    CERN Multimedia

    Staff Association

    2012-01-01

    For the last 15 years contract policy has been one of the top priorities of CERN staff, as expressed in successive surveys initiated by the Staff Association. In one’s professional life, having some forward vision of one’s career prospects is the key to loyalty and motivation. On the contrary, instability about the future is always at the root of anxiety, conflicts, or even health problems. A good employer must therefore balance the needs of the Company and those of its employees. CERN’s current contract policy, as described in the Administrative Circular No 2, states that staff members should first obtain a limited duration (LD) contract of up to five years. Then, if they want to stay in the Organization, staff members must apply, usually once a year, and before the end of their LD contract, for an indefinite contract (IC) post. All candidates for an IC post are considered by the Review Board for the award of indefinite contracts (Review Board) which will choose the most suita...

  14. Control over Administrative Contract Formation

    Directory of Open Access Journals (Sweden)

    Frane Staničić

    2016-02-01

    Full Text Available Administrative contracts in Croatian legislation represent a novelty introduced into the General Administration Procedure Act in 2010. This is a novelty which has not proved to be successful in practice. Control over administrative contract formation is inevitable and is very significant for a number of reasons. Firstly, public legal bodies which form them do so by exercising their own public powers which are without doubt subject to legality control; secondly, in forming administrative contracts, public funds are used which must be controlled; thirdly, forming administrative contracts often touches on using public goods. Due to the restrictive interpretation of administrative contracts in Croatian legislation, this institute is indisputably only regulated in the General Taxation Act. However, for more than two decades contracts which satisfy all presumptions have existed in our law in order to be considered as administrative contracts. It is for this reason that control over contracts will be dealt with for contracts considered by the author to be administrative contracts. These are contracts on concessions and contracts on public procurement. How inadequate today’s regulation of control of administrative contract formation is will be demonstrated, particularly regarding contracts on concession and public procurement. Legislative changes will be proposed which should result in a more quality system of control over administrative contract formation. How control over administrative contract formation cannot be considered as separate from control over administrative contract execution will also be shown.

    Full Text Available In Thailand, poultry sector is the main economic growth of livestock sector, especially broiler production. The rapid expansion in broiler production has been made possible by the increase in the number of commercial farms or contract farming. The objective of this research was to understand better how contract farming works, who gets involved and why and who benefits from the agreement. The study is based on the broiler file survey in Chiang Mai province of Thailand. As the results, contract farming looks quite attractive for farmers as well as for private companies but most of the farmers complained about long waiting until the delivery of the next cycle of chicks have started.

  20. Asymptotics of Random Contractions

    Hashorva, Enkelejd; Tang, Qihe

    2010-01-01

    In this paper we discuss the asymptotic behaviour of random contractions $X=RS$, where $R$, with distribution function $F$, is a positive random variable independent of $S\\in (0,1)$. Random contractions appear naturally in insurance and finance. Our principal contribution is the derivation of the tail asymptotics of $X$ assuming that $F$ is in the max-domain of attraction of an extreme value distribution and the distribution function of $S$ satisfies a regular variation property. We apply our result to derive the asymptotics of the probability of ruin for a particular discrete-time risk model. Further we quantify in our asymptotic setting the effect of the random scaling on the Conditional Tail Expectations, risk aggregation, and derive the joint asymptotic distribution of linear combinations of random contractions.

    Following a brief account of the puzzle that ethics committees present for the Western Philosophical tradition, I will examine the possibility that social contract theory can contribute to a philosophical account of these committees. Passing through classical as well as contemporary theories, particularly Rawls' recent constructivist approach, I will argue that social contract theory places severe constraints on the authority that may legitimately be granted to ethics committees. This, I conclude, speaks more about the suitability of the theory to this level of analysis than about the ethics committee phenomenon itself.

Public interest is un-distributable, unrealistic and without a certain subject.Personal rights and public interests are different in nature.Conflicts between public interests and personal rights shall be balanced with principle theories, while personal rights shall be given initial priority.Where public interest is unobvious or uncertain, the validity of a contract shall be protected.There are four types of social public interests, namely those of basic rights protection, state-owned property protection, public security protection and legal orders protection.%  社会公共利益原则是中国法律确立的原则。《合同法》第52条第4项致合同无效的社会公共利益应采狭义说,以区别于社会公德和公共政策,仅限于法律体系内部所提出的确定要求。公共利益具有不可分配性、非现实性、主体不特定性等特征,个人权利与公共利益不具有同一性。公共利益与个人权利的冲突需要采用原则理论进行价值权衡,且个人权利具有初显优先性,在公共利益不明显或不确定时,应维护合同效力。社会公共利益存在基本权利保护型、国有资产保护型、公共安全保护型和法秩序维护型等四种类型。

    1999-11-01

    The lattice-Boltzmann (LB) method, derived from lattice gas automata, is a relatively new technique for studying transport problems. The LB method is investigated for its accuracy to study fluid dynamics and dispersion problems. Two problems of relevance to flow and dispersion in porous media are addressed: (i) Poiseuille flow between parallel plates (which is analogous to flow in pore throats in two-dimensional porous networks), and (ii) flow through an expansion-contraction geometry (which is analogous to flow in pore bodies in two-dimensional porous networks). The results obtained from the LB simulations are compared with analytical solutions when available, and with solutions obtained from a finite element code (FIDAP) when analytical results are not available. Excellent agreement is found between the LB results and the analytical/FIDAP solutions in most cases, indicating the utility of the lattice-Boltzmann method for solving fluid dynamics and dispersion problems.

  7. Social Yes; Contract No

    Directory of Open Access Journals (Sweden)

    Russell Hardin

    2014-01-01

    Full Text Available Social contract theory is incoherent and it does not work as desired. Among the most obvious disanalogies is that contracts are enforced by a third party, commonly the state. There is no such external enforcer for a constitution. Contractarian theorists typically ignore all such issues and use the metaphor of contract very loosely to ground a claim that citizens are morally obligated to defer to government by their consent, as the parties to a standard legal contract would be legally obligated. David Hume's term is acquiescence. He compellingly argues that actual citizens do not believe their own legal or political obligations depend on their having agreed to their social order. More often than not our interests are simply better served by acquiescing in the rules of that constitution than by attempting to change it. The forms of commitment that are important for constitutional and even for much of conventional social choice are those that derive from the difficulties of collective action to re-coordinate on new rules. They are inherent in the social structure of the conventions themselves, a structure that often more or less automatically exacts costs from anyone who runs against the conventions without anyone or any institution having to take action against the rule breaker. Establishing a constitution is itself a massive act of coordination that, if it is stable for a while, spawns conventions that depend for their maintenance on their self-generating incentives and expectations and that block alternatives.

    Goldstein, Abraham; Revivo, Ketty; Kreitler, Michal; Metuki, Nili

    2010-12-01

    Following the notion of relative importance of the right hemisphere (RH) in creative thinking, we explored the possibility of enhancing creative problem solving by artificially activating the RH ahead of time using unilateral hand contractions. Participants attempted to complete the Remote Associates Test after squeezing a ball with either their left or right hand. As predicted, participants who contracted their left hand (thus activating the RH) achieved higher scores than those who used their right hand and those who did not contract either hand. Our findings indicate that tilting the hemispheric balance toward the processing mode of one hemisphere by motor activation can greatly influence the outcome of thought processes. Regardless of the specific mechanism involved, this technique has the potential for acting as a therapeutic or remedial manipulation and could have wide applications in aiding individuals with language impairments or other disorders that are believed to be related to hemispheric imbalances.

    We give a contemporary and direct derivation of a classical, but insufficiently familiar, result in the theory of linear elasticity—a representation for the energy of a stressed elastic rod with central axis that intrinsically takes the shape of a general space curve. We show that the geometric torsion of the space curve, while playing a crucial role in the bending energy, is physically unrelated to the elastic twist. We prove that the twist energy vanishes in the lowest-energy states of a rod subject to constraints that do not restrict the twist. The stretching and contraction energies of a free helical spring are computed. There are local high-energy minima. We show the possibility of using the spring to model the chirality of DNA. We then compare our results with an available atomic level energy simulation that was performed on DNA unconstrained in the same sense as the free spring. We find some possible reflections of springlike behavior in the mechanics of DNA, but, unsurprisingly, the base pairs lend a material substance to the core of DNA that a spring does not capture.

  2. Dupuytren's Contracture: Fibroblast Contraction?

    Science.gov (United States)

    Gabbiani, Giulio; Majno, Guido

    1972-01-01

    In 6 cases of Dupuytren's disease and 1 of Ledderhose's disease, the nodules of the palmar and plantar aponeurosis were examined by light and electron microscopy. The cells composing these nodules, presumably fibroblasts, showed three significant ultrastructural features: (1) a fibrillar system similar to that of smooth muscle cells; (2) nuclear deformations such as are found in contracted cells, the severest being recognizable by light microscopy (cross-banded nuclei); (3) cell-to-cell and cell-to-stroma attachments. Based on these data and on recent information about the biology of the fibroblasts, it is suggested that these cells are fibroblasts that have modulated into contractile cells (myofibroblasts), and that their contraction plays a role in the pathogenesis of the contracture observed clinically.

    Competitive bidding for electric power is maturing. Increasing numbers of utilities are soliciting proposals from private suppliers. The amount of capacity being sought is increasing, and potential suppliers appear to be abundant. Analysis of these developments still remains limited. Evidence on the behavior of this market is scarce and sketchy. The underlying economic principles that are shaping the market have not clearly been articulated. In this report we examine the economics of competitive bidding both empirically and analytically. Previous study of this market has focused on the evaluation criteria specified in Requests for Proposals (RFPs), and highly aggregated summary statistics on participation and results. We continue the examination of RFPs, but also survey the details of long term contracts that have emerged from competitive bidding. Contracts provide a new level of specific detail that has not been previously available. 68 refs., 13 figs., 25 tabs.

    Full Text Available Objective to study the procedure of exiting the contract its costs and benefits. Methods statistical method comparative analysis. Results free exit from contract is one of the most powerful tools for the consumer rights protection. The procedure frees consumers from bad deals and keeps businesses honest. Yet consumers often choose transactions with lockin provisions trading off exit rights for other perks. This article examines the costs and benefits of free exit as compared to the lockin alternative. According to the authors the present regulation of exit penalties in the USA is poorly tailored to address concerns about lockin particularly in light of increasingly ubiquitous marketbased solutions. The article also calls regulatory attention to loyalty rewards which are shown to be as powerful as exit penalties and equally detrimental. Scientific novelty the article reveals a paradoxical state of the law exit regulations in the USA are used most where they are needed least. Termination penalties present an obvishyous target for regulatory intervention while loyalty programs seem benign not warranting any regulatory attention. Practical significance the article is of interest for the Russian juridical science and lawmaking authorities as in Russia the issue of exiting the contract is as topical as in the USA and requires solution which would impair neither the rights of consumers nor the rights of the sellers ofnbspproducts and services. nbsp

    Aldridge, D.R. Jr. [Army Corps of Engineers, Huntsville, AL (United States)

    1995-11-01

    This paper discusses the use of a Shared Energy Savings (SES) contract as the procurement vehicle to provide, install, and maintain closed-loop ground-coupled heat pumps (CLGCHP`s) for 4,003 family-housing units at Fort Polk, Louisiana. In addition to the requirement relative to heat pumps, the contract allows the energy service company (ESCO) to propose additional projects needed to take full advantage of energy cost-saving opportunities that may exist at Fort Polk. The paper traces the development of the SES contract from feasibility study through development of the request for proposal (RFP) to contract award and implementation. In tracing this development, technical aspects of the project are set forth and various benefits inherent in SES contracting are indicated. The paper concludes that, due to the positive motivation inherent in the shared-savings, as well as partnering aspects of SES contracts, SES contracting is well suited to use as a procurement vehicle.

  15. The Lanthanide Contraction Revisited

    Energy Technology Data Exchange (ETDEWEB)

    Seitz, Michael; Oliver, Allen G.; Raymond, Kenneth N.

    2007-04-19

    A complete, isostructural series of lanthanide complexes (except Pm) with the ligand TREN-1,2-HOIQO has been synthesized and structurally characterized by means of single-crystal X-ray analysis. All complexes are 1D-polymeric species in the solid state, with the lanthanide being in an eight-coordinate, distorted trigonal-dodecahedral environment with a donor set of eight unique oxygen atoms. This series constitutes the first complete set of isostructural lanthanide complexes with a ligand of denticity greater than two. The geometric arrangement of the chelating moieties slightly deviates across the lanthanide series, as analyzed by a shape parameter metric based on the comparison of the dihedral angles along all edges of the coordination polyhedron. The apparent lanthanide contraction in the individual Ln-O bond lengths deviates considerably from the expected quadratic decrease that was found previously in a number of complexes with ligands of low denticity. The sum of all bond lengths around the trivalent metal cation, however, is more regular, showing an almost ideal quadratic behavior across the entire series. The quadratic nature of the lanthanide contraction is derived theoretically from Slater's model for the calculation of ionic radii. In addition, the sum of all distances along the edges of the coordination polyhedron show exactly the same quadratic dependency as the Ln-X bond lengths. The universal validity of this coordination sphere contraction, concomitant with the quadratic decrease in Ln-X bond lengths, was confirmed by reexamination of four other, previously published, almost complete series of lanthanide complexes. Due to the importance of multidentate ligands for the chelation of rare-earth metals, this result provides a significant advance for the prediction and rationalization of the geometric features of the corresponding lanthanide complexes, with great potential impact for all aspects of lanthanide coordination.

    Liu, Miao; Belfore, Lee A.; Shen, Yuzhong; Scerbo, Mark W.

    2010-01-01

    Building a training system for medical personnel to properly interpret fetal heart rate tracing requires developing accurate models that can relate various signal patterns to certain pathologies. In addition to modeling the fetal heart rate signal itself, the change of uterine pressure that bears strong relation to fetal heart rate and provides indications of maternal and fetal status should also be considered. In this work, we have developed a group of parametric models to simulate uterine contractions during labor and delivery. Through analysis of real patient records, we propose to model uterine contraction signals by three major components: regular contractions, impulsive noise caused by fetal movements, and low amplitude noise invoked by maternal breathing and measuring apparatus. The regular contractions are modeled by an asymmetric generalized Gaussian function and least squares estimation is used to compute the parameter values of the asymmetric generalized Gaussian function based on uterine contractions of real patients. Regular contractions are detected based on thresholding and derivative analysis of uterine contractions. Impulsive noise caused by fetal movements and low amplitude noise by maternal breathing and measuring apparatus are modeled by rational polynomial functions and Perlin noise, respectively. Experiment results show the synthesized uterine contractions can mimic the real uterine contractions realistically, demonstrating the effectiveness of the proposed algorithm.

    2015-05-01

    Full Text Available The employment relationship is a contractual one and as such must have all the basic elements of an enforceable contract to make it legally binding. In strict contractual terms, the offer is made by the employer and formally accepted by the employee. Once the acceptance has taken place, there is a legally binding agreement and an action will lie against the party who breaches that agreement, even though it may only just have come into existence. An employment contract, however, is unlike most other contracts. Although the parties will have negotiated the main terms, we shall see that a large number of terms will be implied into the agreement from all sorts of different sources and will not have been individually negotiated by the parties at all. This is what makes an employment contract so different from other contracts. We think this article is an important step in the disclosure of the problem eraised by these two concepts.

    Several performance-driven approaches to selectively enforce interface contracts for scientific components are investigated. The goal is to facilitate debugging deployed applications built from plug-and-play components while keeping the cost of enforcement within acceptable overhead limits. This paper describes a study of global enforcement using a priori execution cost estimates obtained from traces. Thirteen trials are formed from five, single-component programs. Enforcement experiments conducted using twenty-three enforcement policies are used to determine the nature of exercised contracts and the impact of a variety of sampling strategies. Performance-driven enforcement appears to be best suited to programs that exercise moderately expensive contracts.

  9. Location, Location: Jurisdiction & Conflicts in Transborder Contract Litigation

    DEFF Research Database (Denmark)

    Lookofsky, Joseph

    In transborder contract litigation place-based factors are often decisive, both as regards jurisdiction to adjudicate as well as the rules which determine the applicable substantive law. Relevant locations include the place where the contract was made, where the parties reside, transact business...... or own property, the place of delivery, payment or other performance etc. Using concrete case-based examples, Professor Lookofsky explains how rules of jurisdiction and contract conflicts in Europe are tied to rigidly defined, single-place-based factors. In the United States, by contrast...

  11. Neural control of lengthening contractions.

    Science.gov (United States)

    Duchateau, Jacques; Enoka, Roger M

    2016-01-01

    A number of studies over the last few decades have established that the control strategy employed by the nervous system during lengthening (eccentric) differs from those used during shortening (concentric) and isometric contractions. The purpose of this review is to summarize current knowledge on the neural control of lengthening contractions. After a brief discussion of methodological issues that can confound the comparison between lengthening and shortening actions, the review provides evidence that untrained individuals are usually unable to fully activate their muscles during a maximal lengthening contraction and that motor unit activity during submaximal lengthening actions differs from that during shortening actions. Contrary to common knowledge, however, more recent studies have found that the recruitment order of motor units is similar during submaximal shortening and lengthening contractions, but that discharge rate is systematically lower during lengthening actions. Subsequently, the review examines the mechanisms responsible for the specific control of maximal and submaximal lengthening contractions as reported by recent studies on the modulation of cortical and spinal excitability. As similar modulation has been observed regardless of contraction intensity, it appears that spinal and corticospinal excitability are reduced during lengthening compared with shortening and isometric contractions. Nonetheless, the modulation observed during lengthening contractions is mainly attributable to inhibition at the spinal level.

  16. Choreography Synthesis as Contract Agreement

    Directory of Open Access Journals (Sweden)

    Julien Lange

    2013-10-01

    Full Text Available We propose a formal model for distributed systems, where each participant advertises its requirements and obligations as behavioural contracts, and where multiparty sessions are started when a set of contracts allows to synthesise a choreography. Our framework is based on the CO2 calculus for contract-oriented computing, and borrows concepts and results from the session type literature. It supports sessions where the number of participants is not determined beforehand, and keeps CO2's ability to rule out participants that are culpable if contracts are not fulfilled at runtime. We show that we have progress and session fidelity in CO2, as a result of the honesty of participants — i.e., their ability to always adhere to their contracts.

  17. Tensor Network Contractions for #SAT

    Science.gov (United States)

    Biamonte, Jacob D.; Morton, Jason; Turner, Jacob

    2015-09-01

    The computational cost of counting the number of solutions satisfying a Boolean formula, which is a problem instance of #SAT, has proven subtle to quantify. Even when finding individual satisfying solutions is computationally easy (e.g. 2-SAT, which is in ), determining the number of solutions can be #-hard. Recently, computational methods simulating quantum systems experienced advancements due to the development of tensor network algorithms and associated quantum physics-inspired techniques. By these methods, we give an algorithm using an axiomatic tensor contraction language for n-variable #SAT instances with complexity where c is the number of COPY-tensors, g is the number of gates, and d is the maximal degree of any COPY-tensor. Thus, n-variable counting problems can be solved efficiently when their tensor network expression has at most COPY-tensors and polynomial fan-out. This framework also admits an intuitive proof of a variant of the Tovey conjecture (the r,1-SAT instance of the Dubois-Tovey theorem). This study increases the theory, expressiveness and application of tensor based algorithmic tools and provides an alternative insight on these problems which have a long history in statistical physics and computer science.

    T Bhattacharyya; J Eschmeier; J Sarkar

    2006-08-01

    The characteristic function has been an important tool for studying completely non-unitary contractions on Hilbert spaces. In this note, we consider completely non-coisometric contractive tuples of commuting operators on a Hilbert space $\\mathcal{H}$. We show that the characteristic function, which is now an operator-valued analytic function on the open Euclidean unit ball in $\\mathbb{C}^n$, is a complete unitary invariant for such a tuple. We prove that the characteristic function satisfies a natural transformation law under biholomorphic mappings of the unit ball. We also characterize all operator-valued analytic functions which arise as characteristic functions of pure commuting contractive tuples.

  6. Conflict, Contract, Leadership and Innovation: An Interdisciplinary View

    Directory of Open Access Journals (Sweden)

    Gilberto SERAVALLI

    2011-10-01

    Full Text Available The competitive market is able to regulate simple innovative processes. In those of a more complex nature whose principal players may belong to either the same or a different firm a different form of organization is required: one which coherently defines rules and resources designed to avoid, in conditions of uncertainty, tensions arising between the different players which prevent their coordination. In this essay, the hypothesis that such organizations require both contract and leadership will be presented and discussed. The contract is required to en-sure ex-post efficiency, avoiding wastage of resources, and ex-ante efficiency, i.e. mutual commitment between the different players in the innovative process. Leadership is required to progressively manage the conflicts that occur between contrasting visions of how best to proceed that emerge from different specializations, legitimized through a shared commitment. Notwithstanding such characterization, leadership may also not assume the same functions of contract. The contract may not be sufficient and require leadership, but strong leadership cannot replace contract. In such a case, there would be a risk of disengagement. An initial application of this simple model (leadership and contract seems encouraging against competing theories conceiving contract or leadership as sufficient conditions for innovation.

Where the existence of labor agreement / contract employment is expected to harmonize the working relationship with the employer in accordance with the applicable rules. The existence of employment contracts is also a legal instrument which according to researchers ought to be put forward in efforts to increase the qualifications and competence of employees. By contract it will also avoid things that are not desirable in an employment relationship, because each party will always carry out their rights and responsibilities are aligned and balanced.

  8. Cellular contraction precedes membrane depolarization in Vorticella convallaria

    Science.gov (United States)

    Shiono; Naitoh

    1997-01-01

    Application of a mechanical stimulus to the cell body of the peritrich ciliate Vorticella convallaria evoked an all-or-nothing membrane depolarization, the large pulse. This was always accompanied by an all-or-nothing cellular contraction, and simultaneous recordings of the two events revealed that the large pulse was always preceded by the cellular contraction. A smaller graded membrane depolarization (the medium pulse) was sometimes produced in response to a weaker mechanical stimulus. The medium pulse was accompanied by a small, graded, localized contraction of the cell body and was occasionally followed by a large pulse. When a large pulse occurred during a medium pulse, it reached the same peak level as that of a large pulse evoked without a preceding medium pulse. When a medium pulse occurred during a medium pulse, summation of the two pulses was observed. Sustained contraction causes V. convallaria to become rounded, and in this state a mechanical stimulus stronger than that used to evoke the large pulse evoked a graded depolarizing mechanoreceptor potential in the cell. We conclude that both the large and medium pulses are caused by an inward receptor current that is activated mechanically following contraction of the cell body. A localized contraction evokes a small mechanoreceptor current, causing a medium pulse. An all-or-nothing contraction evokes a saturated, all-or-nothing mechanoreceptor current, causing a large pulse.

  15. Framework for Structuring Procurement Contracts

    Directory of Open Access Journals (Sweden)

    Lena Borg

    2014-12-01

    Full Text Available The aim of this paper is to propose a new framework for structuring contract types and payment methods. Concerning procurement contracts, the first important new feature of this framework is a stepwise structure with three main steps in the contract design: (1 what will be procured—should the contract only include construction, or should it include both construction and operation/maintenance (2 who will do the detailed design of the premise and (3 how many contractors will the client use? The second important new feature of this framework is that both step 2 and step 3 include a continuum of alternatives. Concerning payment methods, the new framework is primarily based on how the specific risks of the project are shared. These frameworks can be useful for policy formulation in that they can help to avoid some problematic ways of formulating policies.

  1. The Challenges of the "Software Support for Industrial Controls" Contract

    CERN Document Server

    Ninin, P

    2000-01-01

    ST division is currently specifying a 'Software Support for Industrial Controls' contract. The application of this contract and its success will require several changes in our habits for specifying, designing, and maintaining control systems. This paper summarizes some key concepts which should be respected in order to obtain maximum benefits from the future contract and to optimize the software activities in the division. The contract concerns the maintenance and development of the monitoring and control systems used for supervising CERN's technical infrastructure (electrical distribution, cooling water, air conditioning, safety, and access control). The systems concerned consist of computer and communication hardware and software, tailored to provide specific functionalities for the remote operation, command, and monitoring of equipment. All these systems use commercially available software and hardware such as SCADA, PLCs and associated drivers, controllers, fieldbuses, and networks. It is intended to cont...

  2. Contract grading in clinical evaluation.

    Schoolcraft, V; Delaney, C

    1982-01-01

    The use of contracts in grading clinical performance has provided faculty with a solution to two important problems. One has been how to ensure that students are graded consistently among the various faculty who are grading the same clinical component of a course. The second has been to increase the opportunity for individualized attention to student learning needs. We have been pleased to see all the faculty members increase their input and involvement in the continuing modifications of the contract. Although we have taken the major responsibility for the semi-annual revisions of the contract, other faculty members have been increasingly more explicit in their evaluations and suggestions as their experience with the contract has expanded. Their confidence in this method of clinical evaluation has increased with each semester of use. We plan to continue in the refinement of the instrument and will develop materials for the use of other faculty groups who are interested in developing similar contracts. We are also designing a survey to attempt to discover how widespread is the use of contract grading in clinical areas.

  3. Adiabatic theorems for generators of contracting evolutions

    CERN Document Server

    Avron, J E; Graf, G M; Grech, P

    2011-01-01

    We develop an adiabatic theory for generators of contracting evolution on Banach spaces. This provides a uniform framework for a host of adiabatic theorems ranging from unitary quantum evolutions through quantum evolutions of open systems generated by Lindbladians all the way to classically driven stochastic systems. In all these cases the adiabatic evolution approximates, to lowest order, the natural notion of parallel transport in the manifold of instantaneous stationary states. The dynamics in the manifold of instantaneous stationary states and transversal to it have distinct characteristics: The former is irreversible and the latter is transient in a sense that we explain. Both the gapped and gapless cases are considered. Some applications are discussed.

  16. Psychological contracts of hospice nurses.

    Science.gov (United States)

    Jones, Audrey Elizabeth; Sambrook, Sally

    2010-12-01

    Psychological contracts have been described as individuals' beliefs regarding the obligations, expectations, and contributions that exist between them and their employer. They can be influenced by the organization's culture and philosophy, through human resources policies, and through the employee's personality and characteristics. Owing to the recent economic crisis, hospices in the UK are currently in a transitional phase and are being expected to demonstrate efficiencies that might be more in line with a business model than a health-care environment. This may conflict with the philosophical views of hospice nurses. To support nurses through this transition, it might be helpful to understand the antecedents of hospice nurses' behaviour and how they construct their psychological contracts. Failure to offer adequate support might lead to negative outcomes such as a desire to leave the organisation, poorer quality work, or disruptive behaviour. This study used a modified grounded theory approach involving in-depth interviews to explore the context and content of the psychological contracts of hospice nurses in the UK. Four main themes emerged: the types of psychological contracts formed, how the contracts are formed, their contents, and the breaches and potential violations the nurses perceive.

  20. Contraction of the solar nebula

    Science.gov (United States)

    Rawal, J. J.

    1984-10-01

    The concept of Roche limit is applied to the Laplacian theory of the origin of the solar system to study the contraction of a spherical gas cloud (solar nebula). In the process of contraction of the solar nebula, it is assumed that the phenomenon of supersonic turbulent convection described by Prentice (1978) is operative. It is found that the radius of the contracting solar nebula follows Titius-Bode law Rp = R_sun; ap, where R_sun; is the radius of the present Sun and a = 1.442. The consequences of the relation are also discussed. The aim, here, is an attempt to explain, on the basis of the concept of Roche limit, the distribution of planets in the solar system and try to understand the physics underlying it.

  3. The Contracting Parties' Ability To Conclude The Employment Contract

    Directory of Open Access Journals (Sweden)

    Carmen Constantina NENU

    2014-08-01

    Full Text Available This study's main objective is to analyze certain effects produced by the changes of the Labor Code and by the entry into force of the current Romanian Civil Code. These effects refer to one of the fundamental conditions for the valid conclusion of the individual employment contract, that is, to the legal capacity of employers and employees. Thus, a complete analysis of legal regulations and of the correlations between different provisions on the legal capacity of parties to the individual employment contract is required to identify the existing noncompliance and to propose solutions. The research demonstrated that the current regulatory framework governing the legal capacity of the parties to an individual employment contract does not entirely correspond to the social reality. Therefore, only the employer benefits from a relatively comprehensive statutory regulation on the legal capacity to conclude an individual employment contract. The employee, however, does not benefit from the same attention from legislature. Considering the above, the study represents a significant scientific contribution, whose value lies in the proposed changes to modify legislature, so that the legal capacity of job holders would benefit from fair regulation, in accordance with the principle of legal protection of employee rights.

  4. Debt renegotiation with incomplete contract

    Directory of Open Access Journals (Sweden)

    Paulo de Melo Jorge Neto

    2005-09-01

    Full Text Available A debt contract usually does not include a provision about renegotiation. The right to seize the borrower’s asset and the rules of this process are usually stipulated in the contract. Such a promise not to renegotiate is not credible since renegotiation can mitigate the dead-weight loss of liquidating insolvent borrowers. Once the initial contract may not consider the renegotiation procedure and renegotiation may occur, this paper investigates why a complete contract is not offered. It shows that the lender does not need to stipulate the renegotiation procedure on the initial contract because he is indifferent about committing or not to the terms of a contract. This indicates that a complete contract gives the lender the same expected return as an incomplete contract, in which the renegotiation process is determined after the occurrence of default.Um contrato de débito geralmente não inclui uma cláusula sobre renegociação. O direito de liquidar os ativos do tomador e as regras do processo são habitualmente estipuladas no contrato. Tal promessa de não renegociar não é crível, já que a renegociação pode mitigar a perda bruta de se liquidar tomadores insolventes. Uma vez que o contrato inicial pode não considerar os procedimentos de renegociação, e esta pode, de fato, vir a ocorrer, este artigo investiga a razão de um contrato completo não ser ofertado. Mostra-se que o emprestador não precisa estipular os procedimentos de renegociação no contrato inicial porque ele é indiferente entre se comprometer ou não aos termos do contrato. Isto indica que um contrato completo dá ao emprestador o mesmo retorno esperado de um contrato incompleto, no qual os procedimentos de renegociação são determinados após a declaração de default.

  7. Harmonizing formal requirements for cross-border sales contracts

    Directory of Open Access Journals (Sweden)

    Peter Winship

    2012-07-01

    Full Text Available Legal systems have different traditions about how to “prove” a contract for the sale of personal property. Most legal systems today permit the contract to be proved by any means but some States require that the agreement be concluded in or evidenced by writing. The United Nations Convention on Contracts for the International Sale of Goods adopts a freedom-of-form rule but authorizes a State to declare that the rule does not apply when the seller or buyer has its place of business in that State. This essay studies the consequences of such a declaration. The Convention text does not expressly state the consequences. The Convention’s travaux préparatoires suggest that this silence was deliberate. Doctrine and court opinions are divided on whether the writing formalities of the declaring State always apply or the formalities, if any, of the law applicable by virtue of the rules of private international law govern. In the absence of a consensus, this essay argues that the writing formalities of the declaring State apply. The argument is based on the policies implicit in the decision of non-declaring Contracting States to adhere to a Convention that allows certain Contracting States to opt out of the freedom-of-form rule. The result is consistent with recent private international law treaties that, while providing liberal rules that favor freedom of form, direct application of the fundamental policies not only of the forum but also of other jurisdictions.

  16. Contract portfolio optimization for a gasoline supply chain

    Science.gov (United States)

    Wang, Shanshan

    this model, we characterize a simple and easily implementable dynamic contract portfolio policy that would enable the company to dynamically rebalance its supply contract portfolio over time in anticipation of the future market conditions in each individual channel while satisfying the contractual obligations. The optimal policy is a state-dependent base-share contract portfolio policy characterized by a branded base-share level and an unbranded contract commitment combination, given as a function of the initial information state. Using real-world market data, we estimate the model parameters. We also apply an efficient modified policy iteration method to compute the optimal contract portfolio strategies and corresponding profit value. We present computational results in order to obtain insights into the structure of optimal policies, capture the value of the dynamic contract portfolio policy by comparing it with static policies, and illustrate the sensitivity of the optimal contract portfolio and corresponding profit value in terms of the different parameters. Considering the geographic dispersion of different market areas and the pipeline network together with the dynamic contract portfolio optimization problem, we formulate a forward-looking operational model, which could be used by gasoline suppliers for lower-level planning. Finally, we discuss the generalization of the framework to other problems and applications, as well as further research.

  2. Criteria on Contractions for Entropic Discontinuities of Systems of Conservation Laws

    Science.gov (United States)

    Kang, Moon-Jin; Vasseur, Alexis F.

    2016-10-01

    We study the contraction properties (up to shift) for admissible Rankine-Hugoniot discontinuities of {n× n} systems of conservation laws endowed with a convex entropy. We first generalize the criterion developed in (Serre and Vasseur, J l'Ecole Polytech 1, 2014), using the spatially inhomogeneous pseudo-distance introduced in (Vasseur, Contemp Math AMS, 2013). Our generalized criterion guarantees the contraction property for extremal shocks of a large class of systems, including the Euler system. Moreover, we introduce necessary conditions for contraction, specifically targeted for intermediate shocks. As an application, we show that intermediate shocks of the two-dimensional isentropic magnetohydrodynamics do not verify any of our contraction properties. We also investigate the contraction properties, for contact discontinuities of the Euler system, for a certain range of contraction weights. None of the results involve any smallness condition on the initial perturbation or on the size of the shock.

  3. Evaluation of the mass transfer effect of the stalk contraction cycle of Vorticella

    Science.gov (United States)

    Zhou, Jiazhong; Admiraal, David; Ryu, Sangjin

    2014-03-01

    Vorticella is a protozoan with a contractile stalk that can contract pulling the cell body toward the substrate in less than 10 ms and return to the extended state in a few seconds. Although this stalk contraction is one of the fastest cellular motions, it is unknown why Vorticella contracts. Because the flow field induced by Vorticella shows different characteristics between contraction and relaxation, it has been suggested that Vorticella augments mass transfer near the substrate based on its stalk contraction-relaxation. We investigate this hypothesis using computational fluid dynamics (CFD) simulations and particle image velocimetry (PIV) experiments. In both approaches, Vorticella is modelled as a solid sphere that translates perpendicular to a solid surface in liquid based on the measured stalk length changes of Vorticella. Based on the computationally and experimentally simulated flow, we evaluate the mass transfer capability of Vorticella, for a possible application of the stalk contraction of Vorticella as a biomimetic model system for microfluidic mixers.

    Science.gov (United States)

    1986-06-30

    We know close to nothing why preterm or adterm delivery in human being starts. Either it is the breakdown of mechanisms protecting the pregnancy when it is time for the baby to flee the no more adequate surrounding of the uterus, or the activation of substances starting uterine contractions. Most probable is the interaction between oxytocin and prostaglandines which leads to the onset of labour; the influence of the fetus on this procedure is discussed. Stimulation of contractions: Oxytocin given as infusion with or without foregoing priming by locally applied prostaglandines (exact supervision of uterine motility and the well-being of the fetus by CTG) and/or amniotomy. Infusions of Prostaglandines always cause uterine contractions ending with the expulsion of the fetus. Inhibition of uterine contractility: In cases of threatening premature delivery before during and after intraabdominal operations and fetal distress during term delivery nowadays Betamimetics are given. The application of alcohol is reserved for special cases.

    Greenstein, Joseph L; Winslow, Raimond L

    2011-01-07

    Excitation-contraction coupling in the cardiac myocyte is mediated by a number of highly integrated mechanisms of intracellular Ca²(+) transport. The complexity and integrative nature of heart cell electrophysiology and Ca²(+) cycling has led to an evolution of computational models that have played a crucial role in shaping our understanding of heart function. An important emerging theme in systems biology is that the detailed nature of local signaling events, such as those that occur in the cardiac dyad, have important consequences at higher biological scales. Multiscale modeling techniques have revealed many mechanistic links between microscale events, such as Ca²(+) binding to a channel protein, and macroscale phenomena, such as excitation-contraction coupling gain. Here, we review experimentally based multiscale computational models of excitation-contraction coupling and the insights that have been gained through their application.

    Generally speaking, the diction of international business contracts is formal and standard. The international business contracts have attributes of legal clauses and stipulate both parties' authorities and duties and other interrelated things. So as to both parties, the international business contracts have legal binding force. Therefore, the diction of international business contracts possesses characteristics of specialization,singleness and steadiness of legal terns or wording.

    De Sousa, P B M; Ramos, Rubens Viana; Sousa, Paulo Benicio Melo de

    2006-01-01

    This paper describes how to perform contract signature in a fair way using quantum information. The protocol proposed permits two partners, users of a communication network, to exchange their signatures with non-repudiation. For this, we assume that there is a trustable arbitrator, responsible for the authentication of the signers and that performs a central task in a quantum teleportation protocol of the XOR function between two classical bits.

  3. Transverse contractions of moving bodies

    Bramanti, D.

    1978-05-11

    One of the most important theoretical consequences of the principle of relativity, i.e. the absence of transverse Lorentz-Fitzgerald contractions in moving bodies, has never been subjected to direct experimental tests. The existing indirect evidence of this absence is discussed, and a simple experiment for testing it directly and with high accuracy is proposed. Some implications of a possible nonnull result of this experiment are also pointed out.

  5. Custom, contract, and kidney exchange.

    Science.gov (United States)

    Healy, Kieran; Krawiec, Kimberly D

    2012-01-01

    In this Essay, we examine a case in which the organizational and logistical demands of a novel form of organ exchange (the nonsimultaneous, extended, altruistic donor (NEAD) chain) do not map cleanly onto standard cultural schemas for either market or gift exchange, resulting in sociological ambiguity and legal uncertainty. In some ways, a NEAD chain resembles a form of generalized exchange, an ancient and widespread instance of the norm of reciprocity that can be thought of simply as the obligation to “pay it forward” rather than the obligation to reciprocate directly with the original giver. At the same time, a NEAD chain resembles a string of promises and commitments to deliver something in exchange for some valuable consideration--that is, a series of contracts. Neither of these salient "social imaginaries" of exchange--gift giving or formal contract--perfectly meets the practical demands of the NEAD system. As a result, neither contract nor generalized exchange drives the practice of NEAD chains. Rather, the majority of actual exchanges still resemble a simpler form of exchange: direct, simultaneous exchange between parties with no time delay or opportunity to back out. If NEAD chains are to reach their full promise for large-scale, nonsimultaneous organ transfer, legal uncertainties and sociological ambiguities must be finessed, both in the practices of the coordinating agencies and in the minds of NEAD-chain participants. This might happen either through the further elaboration of gift-like language and practices, or through a creative use of the cultural form and motivational vocabulary, but not necessarily the legal and institutional machinery, of contract.

  6. CONTROL OF CELLULAR CONTRACTION BY CALCIUM IN VORTICELLA

    1994-04-01

    1. Vorticella extracted with Triton X-100 contracted (i.e. the cell body shrank and the stalk coiled) when the external Ca2+ concentration was raised. The degree of contraction increased with increasing Ca2+ concentration. 2. The threshold Ca2+ concentration for shrinkage of the cell body was identical with that for coiling of the stalk in Vorticella extracted with Triton X-100. 3. Living Vorticella showed a graded shrinkage of the cell body when Ca2+ buffer was injected into the cell body, while the stalk showed coiling of an all-or-nothing type. The degree of shrinkage of the cell body increased with increasing free Ca2+ concentration of the buffer. 4. Living Vorticella showed a sustained contraction in response to external application or intracellular injection of caffeine. The effect of caffeine was inhibited by intracellular injection of procaine or Ruthenium Red. 5. Vorticella injected with Ruthenium Red showed graded shrinkage of the cell body as well as graded coiling of the stalk when Ca2+ buffer was injected into the cell body. 6. Caffeine, procaine and Ruthenium Red had no measurable effect on Ca2+-activated contraction in Vorticella extracted with Triton X-100. 7. It is assumed that regenerative liberation of Ca2+ from the endoplasmic reticulum and/or membranous tubules in the contractile system (Ca2+-induced Ca2+ release) is responsible for evoking contraction of an all-or-nothing type following stimulation in living Vorticella.

    Objective The aim of this study was to compare the contraction stress of a new low-shrinkage silorane-based composite (P 90 ) and a new low-shrinkage nanohybrid composite (Venus Diamond) with two conventional dimethacrylate-based composites using new measuring systems.Methods The materials tested were P 90 (3M ESPE),Venus Diamond (Heraeus),Z 350 (3M ESPE),and Charisma Opal(Heraeus).Shrinkage stress was assessed using a stress-strain analyzer consisting of two opposing attachments,one connected to a load cell and the other fixed to the device.All specimens were light-cured and the contraction stress (MPa) generated during polymerization was continuously recorded for 300 s.The contraction stress after 30,60,300 s were recorded.Results The silorane-based composite (P 90) and new low-shrinkage nanohybrid composite (Venus Diamond ) exhibited significantly lower contraction stress and very slowly cure rate than the conventional dimethacrylate-based composites.Contraction stresses after 300 s were:Z 350[ (4.08 ±0.12) MPa] > Charisma Opal[ ( 1.92 ±0.10) MPa]> Venus Diamond [ ( 1.16 ± 0.03 ) MPa] > P 90 [ ( 0.94 ± 0.04 ) MPa],and significant differences among groups were observed ( P < 0.05).Conclusions A new test system can continuously record the contraction stress during polymerization.The low-shrinkage composites ( P 90 and Venus Diamond) tested in the study show an improvement in terms of reducing contraction stress and reducing cure rate.Some new monomer comoositions of the resin matrix can be valid alternatives to dimethacrylates.%目的 探讨复合树脂聚合收缩应力的测试方法及树脂基质对收缩应力的影响.方法 使用模拟临床条件下的聚合收缩应力测量系统,测量两种以新型单体为基质的复合树脂(P 90、维纳斯钻石)和传统基质复合树脂(Z350和卡瑞斯玛)光照开始后收缩力值变化情况,并测得复合树脂在光照后300 s时的聚合收缩应力值.结果 两种采用新型基

  14. Contractive spectral triples for crossed products

    CERN Document Server

    Paterson, Alan L T

    2012-01-01

    Connes showed that spectral triples encode (noncommutative) metric information. Further, Connes and Moscovici in their metric bundle construction showed that, as with the Takesaki duality theorem, forming a crossed product spectral triple can substantially simplify the structure. In a recent paper, Bellissard, Marcolli and Reihani (among other things) studied in depth metric notions for spectral triples and crossed product spectral triples for $Z$-actions, with applications in number theory and coding theory. In the work of Connes and Moscovici, crossed products involving groups of diffeomorphisms and even of \\'{e}tale groupoids are required. With this motivation, the present paper develops part of the Bellissard-Marcolli-Reihani theory for a general discrete group action, and in particular, introduces coaction spectral triples and their associated metric notions. The isometric condition is replaced by the contractive condition.

    2008-01-01

    There are numerous existing notations and standards in the Web service community. These may be grouped broadly into three competing families, namely; Web Services, Semantic Web, and Electronic Business. Although the families are competing, we expect that applications will cut across them...... and there is a need to map from one to another and to analyze compatibility and other properties. Therefore we survey how they deal with different aspects. We then illustrate with examples, the aspects of contracts captured by one language from each of the three competing families in addition to WSDL, the core...... standard for Web services description. The result is a classification based on the aspects of computations: functionality, protocol, and for instance performance covered by the languages. The classification is used to identify similarities between semantic models and thus find potential mappings between...

    Lu, Shan; Swaminathan, Ganesh; Evans, Samuel; Blackledge, Todd

    2013-06-01

    Major Ampullate (MA) spider silk is among the most impressive biomaterials due to its unparalleled mechanical properties, such as super-contraction and cyclic response to changes in humidity. Electro-spinning enables the generation of engineered silk fibers with controlled parameters and dimentions for various medical and commercial applications. However, their applications hinge on the ability to reproduce the mechanical properties such as a precise expansion-contraction response existed in natural silk fibers. Here, we successfully reproduced MA spider-silk fibers from solutions of natural MA silk proteins via electrospinning, which exhibit the super-contraction and cyclic response to humidity change in a manner mirroring the natural fibers.

Furthermore, the generalized [Formula: see text]-contraction mapping principle has been proved without the uniqueness condition. Meanwhile, the generalized [Formula: see text]-contraction mapping principle has been obtained by using an ingenious method.

  2. Increased muscle glucose uptake during contractions

    DEFF Research Database (Denmark)

    Ploug, Thorkil; Galbo, H; Richter, E A

    1984-01-01

    We reinvestigated the prevailing concept that muscle contractions only elicit increased muscle glucose uptake in the presence of a so-called "permissive" concentration of insulin (Berger et al., Biochem. J. 146: 231-238, 1975; Vranic and Berger, Diabetes 28: 147-163, 1979). Hindquarters from rats...... in severe ketoacidosis were perfused with a perfusate containing insulin antiserum. After 60 min perfusion, electrical stimulation increased glucose uptake of the contracting muscles fivefold. Also, subsequent contractions increased glucose uptake in hindquarters from nondiabetic rats perfused for 1.5 h......-methylglucose uptake increased during contractions and glucose uptake was negative at rest and zero during contractions. An increase in muscle transport and uptake of glucose during contractions does not require the presence of insulin. Furthermore, glucose transport in contracting muscle may only increase if glycogen...

Sci. 728 (1994, 183--197, the author introduced and studied the concept of partial metric spaces, and obtained a Banach type fixed point theorem on complete partial metric spaces. In this paper, we establish the fixed point theorems for generalized $\\alpha$-$\\psi$ contractive mappings in the context of partial metric spaces. As consequences of our main results, we obtain fixed point theorems on partial metric spaces endowed with a partial order and that for cyclic contractive mappings. Our results extend and strengthen various known results. Some examples are also given to show that our generalization from metric spaces to partial metric spaces is real.

  5. Contract System for Circulation of the Right to Rural Land Contractual Management

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    From the perspective of civil subject theory,law of value,comparative law and history of laws,the thesis expounds that the contract on the transfer of the contractual right of rural lands is in nature a civil contract instead of an administrative one.Then it explores the defects in the contract from the viewpoint of legal value goal,contract law and legal sociology,that is,the relevant provisions in Rural Land Contract Law and Explanations of Supreme People’s Court about the Issues concerning the Laws Applicable to the Trial of Cases of Disputes over Rural Land Contracting go against the principle of free contracting and run counter to the legal value goal of justice,so they do not achieve good implementing effect.Finally,the thesis demonstrates and makes some practical legislative proposals to perfect the contract system for circulation of the right to operate constructed rural lands,aiming at improving the circulation rate through perfecting the contract of the right to rural land contractual management,solving the disputes in rural lands circulation and safeguarding the legitimate rights of the farmers.

    1976-08-01

    The index of isometric contraction formed from the quotient period of isometric contraction in the erect position by period of isometric contraction in lying position gives the possibility to separate between cardially sufficient and cardially insufficient patients with adequately disturbed regulation of the cardiac circulation. The recognition of early stages of the disturbed left-ventricular function is possible. The use of an adequate exact technique in gaining the primary data is to be presumed. Corrections of the frequency of the index of isometric contraction do not improve the evidence. In the borderline region of the index of isometric contraction with values between 1.03 and 1.1 in questionable cases a further differentiation into still normal or already latent insufficient will do by the analysis of the trend of the index of isometric contraction after the application of medicaments. The determination of the change of the direction of the index of isometric contraction after peroral application of nitroglycerin would be justifiable in routine work after the recognition of the initiaction increases in patients with latent heart insufficiency, in patients with a healthy heart it decreases. The clinical value of the index of isometric contraction as a simple test of the circulatory function is highly to be estimated.

  11. The Inclusion of Standard Terms in International Sales Contracts

    S Eiselen

    2011-04-01

    Full Text Available The problem dealing with the inclusion of standard terms and conditions in contracts is a problem that has engaged most legal systems. The United Nations Convention on Contracts for the International Sale of Goods, Vienna 1980 (CISG does not expressly deal with this problem. Accordingly the solution to the issue must be found in an interpretation and application of the general principles found in articles 8, 14 and 18. One of the main objects of the CISG is the harmonisation of international trade law. It is generally recognised that in order to achieve harmonisation it isnecessary that courts should interpret and apply the convention in a consistent and harmonious manner. Unfortunately a number of approaches have emerged from courts around the world in regard to the inclusion of standard terms. German courts have developed a strict approach which requires that the standard terms be madeavailable to the addressee at the time of the conclusion of the contract. They also require that the standard terms be couched in the language of the main contract. In stark contrast an American court has used an approach which is very lax in regard to incorporation, even allowing incorporation after the conclusion of the contract. There is, however a more moderate approach set out in decisions of the Austrian Supreme Court where the court adopted an approach which is more akin to that found in most legal systems, namely that a clear incorporation clause in the contract is sufficient for the effective incorporation of standard terms. The author critically examines the case law, the various approaches and the underlying arguments on which they are based, before reaching the conclusion that the two extreme approaches should be rejected in favour of the more moderate approach. This approach is founded on aproper interpretation of the provisions of the CISG as well as being in step with international trade practice.

    2013-01-01

    Full Text Available Time proportional contracts are such contracts in which the ownership of the property or itsprofits is transferred to the contracting party, proportional to time. This means that the partywill have the right to use or operate the property in determined portion of the year and will beable to intervene in the property permanently or alternately according to the terms of thecontract. This kind of contracts could be formed as a contract of rent, partnership in either theproperty or its profits, common sale conditional to partnership in profits, and the contract ofcompromise. Concerning the essence of such contracts, conclusion in the form of loan,exchange, and the right to benefit is impossible. Hereby, we will try to examine thepossibility of conclusion of time proportional contracts in the form of determined contracts.

  19. Improved Cell Culture Method for Growing Contracting Skeletal Muscle Models

    Marquette, Michele L.; Sognier, Marguerite A.

    2013-01-01

    An improved method for culturing immature muscle cells (myoblasts) into a mature skeletal muscle overcomes some of the notable limitations of prior culture methods. The development of the method is a major advance in tissue engineering in that, for the first time, a cell-based model spontaneously fuses and differentiates into masses of highly aligned, contracting myotubes. This method enables (1) the construction of improved two-dimensional (monolayer) skeletal muscle test beds; (2) development of contracting three-dimensional tissue models; and (3) improved transplantable tissues for biomedical and regenerative medicine applications. With adaptation, this method also offers potential application for production of other tissue types (i.e., bone and cardiac) from corresponding precursor cells.

  1. Threephasic contractions in mammalian myocardium. Isolation and identification of a late component. Implications for rested-state contractions.

    Science.gov (United States)

    Schüttler, K; Szymanski, G

    1989-01-01

    More than 100 years after Bowditch's discovery of the "Treppe" phenomenon the mechanism of the striking rate and rhythm dependence of cardiac contraction is not unequivocally established. Beside sophisticated techniques biphasic contractions seemed to be a promising approach. There was soon a general agreement that the first component of biphasic contractions is activated by Ca released from the sarcoplasmic reticulum. About the second component prevails confusion: It does not directly reflect the Ca current, but is somehow related to that. In addition, involvement of Na-Ca exchange is supposed. We produced threephasic contractions by the use of isoproterenol (0.5-.4 microM) in guinea pig papillary muscle. Either by the application of ryanodine (1 microM) or after long periods of rest a ryanodine resistant late component of contraction could be isolated. On reducing the transmembrane Na gradient either by reducing [Na]o or by experimental manoeuvres expected to increase [Na]i. (.5 mM [K]o; 2-8 microM ouabain) this component was found to be increased. The evidence suggests that this component is substantially activated by Ca entering the cell via the sarcolemmal Na-Ca exchange. The ryanodine sensitive first component of threephasic contractions was found to be sensitive to caffeine, isoproterenol and changes in stimulation as well. These findings support the view that it may be generated by Ca induced Ca release from the sarcoplasmic reticulum. The pharmacological properties of the second and third ryanodine sensitive component and its dependence on the stimulation pattern were similar to those of the aftercontraction. They were found to be sensitive to procaine, verapamil, Mg, Ni and isoproterenol.(ABSTRACT TRUNCATED AT 250 WORDS)

    Isotretinoin has been considered a unique drug for acne treatment. However, it is associated with numerous adverse effects. Isotretinoin can trigger premature ventricular contractions. This report describes a 33-year-old-woman who presented with palpitations for 1 week while undergoing 1-month isotretinoin treatment for mild-moderate facial acne. An electrocardiogram and Holter monitoring showed premature ventricular contractions during isotretinoin (Roaccutane, Roche) treatment. Isotretinoin-related premature ventricular contractions were strongly suggested in this case due to the existence of documented premature ventricular contractions on electrocardiograms and the disappearance of these premature ventricular contractions two weeks after termination of the treatment To the authors' knowledge, there has been 1 reported case of premature ventricular contractions linked to isotretinoin use; this report describes a second such case.

  5. Contract-Based Cooperative Spectrum Sharing

    Duan, Lingjie; Huang, Jianwei

    2011-01-01

    Providing proper economic incentives is essential for the success of dynamic spectrum sharing. Cooperative spectrum sharing is one effective way to achieve this goal. In cooperative spectrum sharing, secondary users (SUs) relay traffics for primary users (PUs), in exchange for dedicated transmission time for the SUs' own communication needs. In this paper, we study the cooperative spectrum sharing under incomplete information, where SUs' types (capturing their heterogeneity in relay channel gains and evaluations of power consumptions) are private information and not known by PUs. Inspired by the contract theory, we model the network as a labor market. The single PU is the employer who offers a contract to the SUs. The contract consists of a set of contract items representing combinations of spectrum accessing time (i.e., reward) and relaying power (i.e., contribution). The SUs are employees, and each of them selects the best contract item to maximize his payoff. We study the optimal contract design for both w...

    This paper develops a tow-stage purchase contract for fashion products to manage the buyer's cost. In addition to require a commitment, the purchase contract allows the buyer to adjust the commitment at a later stage. We model the buyer's problem and obtain explicit formulae to describe the buyer's optimal behavior. We analyze the effect of parameters on the buyer's cost and prove that such contract can decrease the buyer's cost numerically.

    Alessandro Mignogna

    2013-11-01

    Full Text Available Exhaustive formal verification for systems of systems (SoS is impractical and cannot be applied on a large scale. In this paper we propose to use statistical model checking for efficient verification of SoS. We address three relevant aspects for systems of systems: 1 the model of the SoS, which includes stochastic aspects; 2 the formalization of the SoS requirements in the form of contracts; 3 the tool-chain to support statistical model checking for SoS. We adapt the SMC technique for application to heterogeneous SoS. We extend the UPDM/SysML specification language to express the SoS requirements that the implemented strategies over the SoS must satisfy. The requirements are specified with a new contract language specifically designed for SoS, targeting a high-level English- pattern language, but relying on an accurate semantics given by the standard temporal logics. The contracts are verified against the UPDM/SysML specification using the Statistical Model Checker (SMC PLASMA combined with the simulation engine DESYRE, which integrates heterogeneous behavioral models through the functional mock-up interface (FMI standard. The tool-chain allows computing an estimation of the satisfiability of the contracts by the SoS. The results help the system architect to trade-off different solutions to guide the evolution of the SoS.

    The electric power liberalization will expand. The method of judging the service selection is requested by customers. The method of comparing each energy unit price based on the average demanded is general. However, there are risks in customer's energy demand in the future. In the supply contract, there is freedom of contract changes according to demand changes. By this contract changes customers can avoid the risks. In this paper, we think that there was value in contract changes and we proposed the new method for analyzing the economy of this value.

    Full Text Available Within this paper we resume a topic widely debated in the specialized literature and always topical, by the implications that it has on the development of public administration and satisfying the general interests. The changes brought to the special legislation led, by identifying certain features, in determining the legal nature of the procurement contract, i.e. the administrative contract. In Romania, this notion is not fully established, although it is recognized by most of doctrinaires. In this paper we intend to identify by analyzing the legislation, the doctrine and jurisprudence, the elements that lead to the integration of public procurement contract in the category of administrative contract.

  18. Some Representation Theorems for Recovering Contraction Relations

    Institute of Scientific and Technical Information of China (English)

    Ping Hou

    2005-01-01

    One of the important topics in the study of contraction inference relations is to establish the representation theorems for them. Various methods have been employed for giving representation of a broad class of contraction operations.However, there was not any canonical approach to dealing with the representation results for the contraction relations in the literature. Recently, in order to obtain the representation result for recovering contraction inference relations satisfying the condition weak conjunctive inclusion (wci), a notion of an image structure associated with the canonical epistemic state has been introduced. Based on the image structure, this paper establishes three representation results for recovering contraction inference relations which satisfy the conditions CL, CR1 and DR* respectively by the standard epistemic AGM states. A unique technique and uniform proofs to represent these contraction relations are adopted, which could overcome the core objection in previous description of contraction relations. The paper shows as well that the image structure and canonical epistemic states can be used not only to get the representation result for wci-recovering contraction relation, but also to provide semantic characterizations for a wide range of recovering contraction relations.

    2010-05-01

    The purpose of this study was to examine perceived exertion responses during concentric and eccentric elbow flexor contractions between young adult men and women. Thirty healthy young adults participated in two experimental sessions. During the first session, subjects performed five concentric isokinetic maximal voluntary contractions (MVC) of elbow flexion, followed by nine, randomly-ordered sub-maximal contractions (10-90% MVC). The same procedures were repeated during the second session, with the exception that eccentric contractions were performed. Subjects rated their perceived exertion following the sub-maximal contractions with the Borg category-ratio scale. Perceived exertion was significantly (pMVC. A three-factor interaction between 30-40% MVC indicated that perceived exertion increased more during the eccentric, than concentric, contractions in women, while the opposite pattern was evident for the men. There were no significant contraction mode or gender differences. Power function modeling revealed that perceived exertion increased in a negatively accelerating manner, except for the men performing eccentric exercise. Perceived exertion increases in a similar non-linear manner between men and women during concentric contractions, while men exhibited a statistically linear pattern during eccentric contractions.

  6. Stimulated contractions delay and prolong central fatigue compared with voluntary contractions in men.

    2013-05-01

    Voluntary and stimulated contractions are commonly used in sports training and rehabilitation, and it is well known that both these kinds of contractions generate central fatigue. However, to date, there is a lack of research on the comparison of the mechanisms by which these 2 exercises induce central disturbances. Central fatigue can be characterized by central activation failure during maximal voluntary contraction (MVC). Superimposition of an electrical stimulation onto MVC has been used to detect central activation failure. Completeness of activation has been quantified by the central activation ratio (CAR) = MVC/(MVC + stimulated force). The aim was not only to evaluate the CAR immediately after fatiguing voluntary (VOL) and stimulated (STIM) contractions but also to compare recovery duration over different time periods (prefatigue: PRE condition; immediate postfatigue: POST condition; after a 5-minute recovery: POST 5 condition; after a 30-minute recovery: POST 30 condition) (n = 18). Results showed that in the POST condition, the CAR is more affected for the VOL contractions than for the STIM contractions (p contractions only in the POST 5 condition (p contractions, whereas it was complete for the VOL contractions (p contractions alter the CAR more than the STIM contractions immediately after their completion. However, the effects of the STIM contractions on the CAR are delayed and prolonged.

  6. Contraction stress test by intermittent nipple stimulation.

    Huddleston, J F; Sutliff, G; Robinson, D

    1984-05-01

    Although the nonstress test has generally supplanted the contraction stress test as the primary test for assessment of fetal well-being, the contraction stress test continues to be useful. Objectionable factors of the contraction stress test have included the time required to complete the test and the frequent necessity for intravenous oxytocin. The authors developed a contraction stress test protocol using contractions produced by intermittent nipple stimulation and used the method for 345 tests on 193 high-risk pregnancies during a 15-month period. The women were instructed to stimulate one breast, through their clothes, for two minutes and then to rest for five minutes. This cycle was repeated as necessary, but was interrupted whenever contractions began. Using this protocol, the authors were successful in achieving an adequate contraction frequency with every attempt, and hyperstimulation was not more frequent than previously reported with the standard contraction stress test. The average time requirement was 45 minutes. No unexplained stillbirths occurred after a negative test.

  20. Enhanced computational efficiency in the direct determination of the two-electron reduced density matrix from the anti-Hermitian contracted Schrödinger equation with application to ground and excited states of conjugated π-systems

    Determination of the two-electron reduced density matrix (2-RDM) from the solution of the anti-Hermitian contracted Schrödinger equation (ACSE) yields accurate energies and properties for both ground and excited states. Here, we develop a more efficient method to solving the ACSE that uses second-order information to select a more optimal step towards the solution. Calculations on the ground and excited states of water, hydrogen fluoride, and conjugated π systems show that the improved ACSE algorithm is 10-20 times faster than the previous ACSE algorithm. The ACSE can treat both single- and multi-reference electron correlation with the initial 2-RDM from a complete-active-space self-consistent-field (CASSCF) calculation. Using the improved algorithm, we explore the relationship between truncation of the active space in the CASSCF calculation and the accuracy of the energy and 2-RDM from the ACSE calculation. The accuracy of the ACSE, we find, is less sensitive to the size of the active space than the accuracy of other wavefunction methods, which is useful when large active space calculations are computationally infeasible.

  6. INFLUENCE FACTORS FOR LEASING MARKET CONTRACTS

    Directory of Open Access Journals (Sweden)

    Oana BĂRBULESCU

    2016-11-01

    Full Text Available This paper aims to investigate the relationship between leasing contracts and some factors that influence the value of these contracts. In order to do this, we have decided on some quantitative marketing research by appealing to statistics for accomplishing the objectives that we have set: to find a correlation between the turnover percentage assigned to leasing expenses and several influence factors. This study indicated that the more contracts are signed by a firm, the more likely is to assign a bigger fraction of the income to each new leasing contract. The study confirmed that bigger companies are relying more on leasing as a way of financing than small companies. This study also discovered that companies with more employees are using larger contracts in order to sustain their activity. The findings are expected to contribute to adjusting the offers by the leasing companies, taking into consideration these factors and to using these factors in order to better predict the market evolution.

  7. Alternatives in polymerization contraction stress management

    Directory of Open Access Journals (Sweden)

    Roberto R. Braga

    2004-01-01

    Full Text Available Polymerization contraction stress of dental composites is often associated with marginal and interfacial failure of bonded restorations. The magnitude of the stress depends on the composite's composition (filler content and matrix composition and its ability to flow before gelation, which is related to the cavity configuration and curing characteristics of the composite. This article reviews the variations found among studies regarding the contraction stress testing method, contraction stress values of current composites, and discusses the validity of contraction stress studies in relation to results from microleakage tests. The effect of lower curing rates and alternative curing routines on contraction stress values is also discussed, as well as the use of low elastic modulus liners. Moreover, studies with experimental Bis-GMA-based composites and recent developments in low-shrinkage monomers are described.

    This paper studies the impacts of physical contracts and financial contracts on the bidding strategies of GENCOs, including Physical Bilateral Contracts, Contracts for Difference (CfDs), Call Options and Put Options under discriminatory pricing mechanism. The integrated bidding decision model is applied, which has three main modules - probabilistic local marginal price simulator, market-oriented unit commitment model and multi-criteria decision system. The numerical results show that the GENCO will choose different bidding strategies if it holds different types of contract. The results also suggest that CfDs have the best performance for risk alleviation. (author)

  2. High K+-induced contraction requires depolarization-induced Ca2+ release from internal stores in rat gut smooth muscle

    Timo KIRSCHSTEIN; Mirko REHBERG; Rika BAJORAT; Tursonjan TOKAY; Katrin PORATH; Rudiger KOHLING

    2009-01-01

    Aim: Depolarization-induced contraction of smooth muscle is thought to be mediated by Ca2+influx through voltage-gated L-type Ca2+channels. We describe a novel contraction mechanism that is independent of Ca2+ entry.Methods: Pharmacological experiments were carried out on isolated rat gut longitudinal smooth muscle preparations, measuring iso-metric contraction strength upon high K+-induced depolarization.Results: Treatment with verapamil, which presumably leads to a conformational change in the channel, completely abolished K+-induced contraction, while residual contraction still occurred when Ca2+ entry was blocked with Cd2+. These results were further con-firmed by measuring intracellular Ca2+ transients using Fura-2. Co-application of Cd2+ and the ryanodine receptor blocker DHBP further reduced contraction, albeit incompletely. Additional blockage of either phospholipase C (U 73122) or inositol 1,4,5-trisphophate (IP3)receptors (2-APB) abolished most contractions, while sole application of these blockers and Cd2+ (without parallel ryanodine receptor manipulation) also resulted in incomplete contraction block.Conclusion: We conclude that there are parallel mechanisms of depolarization-induced smooth muscle contraction via (a) Ca2+ entry and (b) Ca2+ entry-independent, depolarization-induced Ca2+-release through ryanodine receptors and IP3, with the latter being depen-dent on phospholipase C activation.

  3. Bonneville Purchasing Instructions. Appendix 14A, Contracting Officer`s Technical Representatives` Guide for Services Contracts.

    Energy Technology Data Exchange (ETDEWEB)

    United States. Bonneville Power Administration.

    1993-07-01

    This guide outlines the duties of BPA personnel designated as Contracting Officers Technical Representatives (COTRs). The BPA Administrator gives contracting officers (COs) in BPA responsibility and authority for awarding and administering contracts. COs are authorized to designate other BPA employees to act as their representatives for purposes of contract administration, from the time of contract award until final receipt and acceptance of the contracted services. COTRs are the individuals primarily relied upon to perform technical contract administration functions. Similar functions for supply and construction contracts are performed by engineering representatives, construction inspectors, and inspectors. Although this Guide is written primarily with the COTR in mind, the concept and operation of teamwork is essential throughout the entire process of contract administration. The CO administers the contract during performance, but rarely has expertise in all of the relevant technical areas. Therefore, CO decisions rely on input from a team. The COTR is an indispensable member of that team. The instructions in this Guide are designed to facilitate this essential CO-COTR cooperation. COTR duties are usually additional to those required of the COTR in his or her assigned line organization. The COTR is still accountable to the line supervisor for performance of regularly-assigned duties. These duties are to be reflected appropriately in performance appraisals and job descriptions. For contract administration duties, however, the COTR reports directly to, and is accountable only to, the CO. The COTR`s supervisor must allow sufficient time to ensure that the COTR can adequately monitor the contract for technical compliance. This Guide is designed for COTRs who are performing service contract (including intergovernmental contract) administration functions as an adjunct to their normal technical duties.

  6. Contracting out of clinical services in Zimbabwe.

    McPake, B; Hongoro, C

    1995-07-01

    Contracting is increasingly recommended to developing countries as a way of improving the efficiency of the health sector. However, empirical evidence regarding its effectiveness in this respect is almost completely absent. In Zimbabwe, a long standing contract exists between the Ministry of Health and Wankie Colliery to provide clinical services in the Colliery's 400 bed hospital. This paper details a study of the Zimbabweans' experience with the contract. Its success is assessed using comparisons with a neighbouring government hospital of the price of services (vs the cost in the government hospital); the situation of hospital workers; and the quality of services delivered. The Colliery has established a monopoly position for hospital services in the district. However, it appears to offer services of at least as good quality at prices which are lower than the unit costs of the government hospital when capital costs are included. Nevertheless, the contract cannot be considered a success due to the failure to contain its total cost. Approximately 70% of provincial non-salary recurrent expenditure is consumed by the contract while only a minority of the province's population have access to the Colliery hospital. Screening patients, both with respect to their ability to pay and to their need for secondary level services does not take place with the result that utilization levels are not controlled. The study highlights a number of important issues affecting contracting in developing country setting: First, contracted institutions attain powerful bargaining positions if there are no viable competitors and the government does not itself retain capacity to offer an alternative service. Second, specific skills are needed for the management of contracts at all levels. If the process of contract development responds to a crisis driven agenda resulting from civil service retrenchment and public expenditure cuts, it is unlikely that adequate consideration will be given to

  8. A Module Language for Typing by Contracts

    Glouche, Yann; Talpin, Jean-Pierre; LeGuernic, Paul; Gautier, Thierry

    2009-01-01

    Assume-guarantee reasoning is a popular and expressive paradigm for modular and compositional specification of programs. It is becoming a fundamental concept in some computer-aided design tools for embedded system design. In this paper, we elaborate foundations for contract-based embedded system design by proposing a general-purpose module language based on a Boolean algebra allowing to define contracts. In this framework, contracts are used to negotiate the correctness of assumptions made on the definition of a component at the point where it is used and provides guarantees to its environment. We illustrate this presentation with the specification of a simplified 4-stroke engine model.

  9. From Orchestration to Choreography through Contract Automata

    Directory of Open Access Journals (Sweden)

    Davide Basile

    2014-10-01

    Full Text Available We study the relations between a contract automata and an interaction model. In the former model, distributed services are abstracted away as automata - oblivious of their partners - that coordinate with each other through an orchestrator. The interaction model relies on channel-based asynchronous communication and choreography to coordinate distributed services. We define a notion of strong agreement on the contract model, exhibit a natural mapping from the contract model to the interaction model, and give conditions to ensure that strong agreement corresponds to well-formed choreography.

  14. Interaction between muscarinic receptor subtype signal transduction pathways mediating bladder contraction.

    Science.gov (United States)

    Braverman, Alan S; Tallarida, Ronald J; Ruggieri, Michael R

    2002-09-01

    M(3) muscarinic receptors mediate cholinergic-induced contraction in most smooth muscles. However, in the denervated rat bladder, M(2) receptors participate in contraction because M(3)-selective antagonists [para-fluoro-hexahydro-sila-diphenidol (p-F-HHSiD) and 4-DAMP] have low affinities. However, the affinity of the M(2)-selective antagonist methoctramine in the denervated bladder is consistent with M(3) receptor mediating contraction. It is possible that two pathways interact to mediate contraction: one mediated by the M(2) receptor and one by the M(3) receptor. To determine whether an interaction exists, the inhibitory potencies of combinations of methoctramine and p-F-HHSiD for reversing cholinergic contractions were measured. In normal bladders, all combinations gave additive effects. In denervated bladders, synergistic effects were seen with the 10:1 and 1:1 (methoctramine:p-F-HHSiD wt/wt) combinations. After application of the sarcoplasmic reticulum ATPase inhibitor thapsigargin to normal tissue, the 10:1 and 1:1 ratios became synergistic, mimicking denervated tissue. Thus in normal bladders both M(2) and M(3) receptors can induce contraction. In the denervated bladder, the M(2) and the M(3) receptors interact in a facilitatory manner to mediate contraction.

  18. Contracts, trust and information systems innovation

    Directory of Open Access Journals (Sweden)

    Liliana Lopez Jimenez

    Full Text Available This paper discusses the use of contracts as the prevailing coordination mechanism in IS innovation processes in which an external provider is appointed. Drawing from a theoretical framework founded on systems theory, structuration theory and neo-institutionalism, this paper argues that IS innovations take place in a relatively weak institutional context, which accounts for the generalised preference for contracts over other coordination mechanisms (i.e. trust as a means of governing interorganizational exchange. Based on secondary data, two constituent elements of the institutional context of IS innovations are analysed, namely the institutional aspects of the IT industry and the legal system. Our argument has both academic and practical implications. Academic implications emphasize the importance of acknowledging the institutional dimension of contracts and trust. Regarding practice, the need for a better understanding of the role of contracts is suggested.

  2. Algebraically contractible topological tensor network states

    CERN Document Server

    Denny, S J; Jaksch, D; Clark, S R

    2011-01-01

    We adapt the bialgebra and Hopf relations to expose internal structure in the ground state of a Hamiltonian with $Z_2$ topological order. Its tensor network description allows for exact contraction through simple diagrammatic rewrite rules. The contraction property does not depend on specifics such as geometry, but rather originates from the non-trivial algebraic properties of the constituent tensors. We then generalise the resulting tensor network from a spin-half lattice to a class of exactly contractible states on spin-S degrees of freedom, yielding the most efficient tensor network description of finite Abelian lattice gauge theories. We gain a new perspective on these states as examples of two-dimensional quantum states with algebraically contractible tensor network representations. The introduction of local perturbations to the network is shown to reduce the von Neumann entropy of string-like regions, creating an unentangled sub-system within the bulk in a certain limit. We also show how perturbations l...

    Highlights: •Photochromic yttrium hydride films (YH:O) were prepared by reactive sputtering. •Black and transparent YH:O films were studied by time-resolved synchrotron XRD. •Both YH:O samples showed a lattice contraction upon illumination. •Also exposure to the X-ray beam itself results in a lattice contraction. -- Abstract: A strong photochromic effect was recently discovered in thin films of oxygen-containing yttrium hydride taking place at room temperature and reacting to ultraviolet and visible light. In this paper, we report on a lattice contraction upon illumination observed for thin-film samples of photochromic yttrium hydride, recorded by time-resolved X-ray diffraction using synchrotron radiation. The time dependence of the lattice contraction is consistent with the observed photochromic response of the samples.

  13. A DIC Based Technique to Measure the Contraction of a Skeletal Muscle Engineered Tissue

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Tissue engineering is a multidisciplinary science based on the application of engineering approaches to biologic tissue formation. Engineered tissue internal organization represents a key aspect to increase biofunctionality before transplant and, as regarding skeletal muscles, the potential of generating contractile forces is dependent on the internal fiber organization and is reflected by some macroscopic parameters, such as the spontaneous contraction. Here we propose the application of digital image correlation (DIC as an independent tool for an accurate and noninvasive measurement of engineered muscle tissue spontaneous contraction. To validate the proposed technique we referred to the X-MET, a promising 3-dimensional model of skeletal muscle. The images acquired through a high speed camera were correlated with a custom-made algorithm and the longitudinal strain predictions were employed for measuring the spontaneous contraction. The spontaneous contraction reference values were obtained by studying the force response. The relative error between the spontaneous contraction frequencies computed in both ways was always lower than 0.15%. In conclusion, the use of a DIC based system allows for an accurate and noninvasive measurement of biological tissues’ spontaneous contraction, in addition to the measurement of tissue strain field on any desired region of interest during electrical stimulation.

  14. Contraction preconditioner in finite-difference electromagnetic modeling

    Science.gov (United States)

    Yavich, Nikolay; Zhdanov, Michael S.

    2016-06-01

    This paper introduces a novel approach to constructing an effective preconditioner for finite-difference (FD) electromagnetic modeling in geophysical applications. This approach is based on introducing an FD contraction operator, similar to one developed for integral equation formulation of Maxwell's equation. The properties of the FD contraction operator were established using an FD analog of the energy equality for the anomalous electromagnetic field. A new preconditioner uses a discrete Green's function of a 1D layered background conductivity. We also developed the formulas for an estimation of the condition number of the system of FD equations preconditioned with the introduced FD contraction operator. Based on this estimation, we have established that for high contrasts, the condition number is bounded by the maximum conductivity contrast between the background conductivity and actual conductivity. When there are both resistive and conductive anomalies relative to the background, the new preconditioner is advantageous over using the 1D discrete Green's function directly. In our numerical experiments with both resistive and conductive anomalies, for a land geoelectrical model with 1:10 contrast, the method accelerates convergence of an iterative method (BiCGStab) by factors of 2 to 2.5, and in a marine example with 1:50 contrast, by a factor of 4.6, compared to direct use of the discrete 1D Green's function as a preconditioner.

    The lanthanide contraction is conceptualized traditionally through coordination chemistry. Here we break this mold in a structural study of lanthanide ions dissolved in an amphiphilic liquid. The lanthanide contraction perturbs the weak interactions between molecular aggregates that drive mesoscale assembly and emergent behavior. The weak interactions correlate with lanthanide ion transport properties, suggesting new strategies for rare-earth separation that exploit forces outside of the coordination sphere.

    2009-01-01

    We study the asymptotic behaviour of contractive operators and strongly continuous semigroups on separable Hilbert spaces using the notion of rigidity. In particular, we show that a "typical" contraction $T$ contains the unit circle times the identity operator in the strong limit set of its powers, while $T^{n_j}$ converges weakly to zero along a sequence $\\{n_j\\}$ with density one. The continuous analogue is presented for isometric ang unitary $C_0$-(semi)groups.

    The notion of contract aware components has been published roughly ten years ago and is now becoming mainstream in several fields where the usage of software components is seen as critical. The goal of this paper is to survey domains such as Embedded Systems or Service Oriented Architecture where the notion of contract aware components has been influential. For each of these domains we briefly describe what has been done with this idea and we discuss the remaining challenges.

    2006-01-01

    This paper presents a simple analytical model, developed using the energy and continuity equations,for the computation of the live-bed scour depth in long contractions. The model agrees satisfactorily with experimental data. Equations previously proposed in the literature for estimation of the equilibrium scour depth in long contractions are compared with experimental data. The comparison indicates that the equation given by Lim is the best predictor among those examined.

  4. Agricultural production contract in American law

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Nowadays agricultural production is more and more based on the production contracts. There are many types of them that can be conducted by a farmer and processing plants, brokers, etc. Signing the contract a farmer reduces the production risk and stabilizes his revenue. Because the legal system varies from state to state there are some regularities and models that can be followed. Unfortunately the differences do not allow to define one common pattern of contact.

    In this paper we propose a theory of optimal property rights in a financial contracting setting. Following recent contributions in the property law literature, we emphasize the distinction between contractual rights, that are only enforceable against the parties themselves, and property rights, that are also enforeceable against third parties outside the contract. Our analysis starts with the following question: which contractual agreements should the law allow parties to enforce as property ...

    We outline several properties of IFRS that potentially affect the contractibility or the transparency of financial statement information, and hence the use of that information in debt contracts. Those properties include the increased choice among accounting rules IFRS gives to managers, enhanced rule-making uncertainty, and increased emphasis on fair value accounting. Consistent with reduced contractibility of IFRS financial statement information, we find a significant reduction in accounting...

  10. A coordination theoretic model for three level supply chains using contracts

    Indian Academy of Sciences (India)

    Arshinder; Arun Kanda; S G Deshmukh

    2009-10-01

    Typically, supply chain members are dependent on each other to manage various resources and information. The conflicting objectives and lack of coordination between supply chain members may often cause uncertainties in supply and demand. The basic elements of coordination theory like interdependency, coherency and mutuality may help in effective flow of information and material between the dependent supply chain members. Supply chain contract can be an effective coordination mechanism to motivate all the members to be a part of the entire supply chain. There are different types of supply chain contracts such as buy back and quantity flexibility contracts. Supply chain performance may be substantially improved by properly designing the contracts to share risks and rewards. The objective of this paper is to explore the applicability of coordination elements through an analytical model in three-level (Manufacturer–distributor–retailer) serial supply chains using contracts. The model evaluates the impact of supply chain contracts on various performance measures. The impact of some contract may be on some specific performance measure only, which helps managers to choose the type of contract if there is an objective of improving certain performance measure before hand. In three-level supply chains, the contracts are designed at two distinct interfaces: Manufacturer–distributor and distributor–retailer. The model demonstrates the complexity in evaluating the decision variables of three level supply chains. The proposed model is a novel approach to apply coordination theory at various levels of supply chain. The model also presents how the coordination elements are related to each other in various coordination cases.

  12. Kernel Contraction and Consolidation of Alignment under Ontology Change

    Directory of Open Access Journals (Sweden)

    Ahmed ZAHAF

    2016-08-01

    Full Text Available Alignment overcomes divergence in the specification of the semantics of vocabularies by different but overlapping ontologies. Therefore, it enhances semantic interoperability for many web based applications. However, ontology change following applications new requirements or new perception of domain knowledges can leads to undesirable knowledge such as inconsistent and therefore to a useless alignment. Ontologies and alignments are encoded in knowledge bases allowing applications to store only some explicit knowledge while they derive implicit ones by applying reasoning services on these knowledge bases. This underlying representation of ontologies and alignments leads us to follow base revision theory to deal with alignment revision under ontology change. For that purpose, we adapt kernel contraction framework to design rational operators and to formulate the set of postulates that characterize each class of these operators. We demonstrate the connection between each class of operators and the set of postulates that characterize them. Finally, we present algorithms to compute alignment kernels and incision functions. Kernels are sets of correspondences responsible of undesirable knowledge following alignment semantics. Incision functions determine the sets of correspondences to eliminate in order to restore alignment consistency or to realize a successful contraction.

    We characterize those Lie groups, and algebraic groups over a local field of characteristic zero, whose first reduced L^p-cohomology is zero for all p>1, extending a result of Pansu. As an application, we obtain a description of Gromov-hyperbolic groups among those groups. In particular we prove that any non-elementary Gromov-hyperbolic algebraic group over a non-Archimedean local field of zero characteristic is quasi-isometric to a 3-regular tree. We also extend the study to semidirect products of a general locally compact group by a cyclic group acting by contracting automorphisms.

  15. Contraction level-related modulation of corticomuscular coherence differs between the tibialis anterior and soleus muscles in humans.

    The sensorimotor cortex activity measured by scalp EEG shows coherence with electromyogram (EMG) activity within the 15- to 35-Hz frequency band (β-band) during weak to moderate intensity of isometric voluntary contraction. This coupling is known to change its frequency band to the 35- to 60-Hz band (γ-band) during strong contraction. This study aimed to examine whether such contraction level-related modulation of corticomuscular coupling differs between muscles with different muscle compositions and functions. In 11 healthy young adults, we quantified the coherence between EEG over the sensorimotor cortex and rectified EMG during tonic isometric voluntary contraction at 10-70% of maximal voluntary contraction of the tibialis anterior (TA) and soleus (SOL) muscles, respectively. In the TA, the EEG-EMG coherence shifted from the β-band to the γ-band with increasing contraction level. Indeed, the magnitude of β-band EEG-EMG coherence was significantly decreased, whereas that of γ-band coherence was significantly increased, when the contraction level was above 60% of maximal voluntary contraction. In contrast to the TA, the SOL showed no such frequency changes of EEG-EMG coherence with alterations in the contraction levels. In other words, the maximal peak of EEG-EMG coherence in the SOL existed within the β-band, irrespective of the contraction levels. These findings suggest that the central nervous system regulates the frequency of corticomuscular coupling to exert the desired levels of muscle force and, notably, that the applicable rhythmicity of the coupling for performing strong contractions differs between muscles, depending on the physiological muscle compositions and functions of the contracting muscle.

  16. Natural gas contracts in efficient portfolios

    Energy Technology Data Exchange (ETDEWEB)

    Sutherland, R.J.

    1994-12-01

    This report addresses the {open_quotes}contracts portfolio{close_quotes} issue of natural gas contracts in support of the Domestic Natural Gas and Oil Initiative (DGOI) published by the U.S. Department of Energy in 1994. The analysis is a result of a collaborative effort with the Public Service Commission of the State of Maryland to consider {open_quotes}reforms that enhance the industry`s competitiveness{close_quotes}. The initial focus of our collaborative effort was on gas purchasing and contract portfolios; however, it became apparent that efficient contracting to purchase and use gas requires a broader consideration of regulatory reform. Efficient portfolios are obtained when the holder of the portfolio is affected by and is responsible for the performance of the portfolio. Natural gas distribution companies may prefer a diversity of contracts, but the efficient use of gas requires that the local distribution company be held accountable for its own purchases. Ultimate customers are affected by their own portfolios, which they manage efficiently by making their own choices. The objectives of the DGOI, particularly the efficient use of gas, can be achieved when customers have access to suppliers of gas and energy services under an improved regulatory framework. The evolution of the natural gas market during the last 15 years is described to account for the changing preferences toward gas contracts. Long-term contracts for natural gas were prevalent before the early 1980s, primarily because gas producers had few options other than to sell to a single pipeline company, and this pipeline company, in turn, was the only seller to a gas distribution company.

  17. Linking myometrial physiology to intrauterine pressure; how tissue-level contractions create uterine contractions of labor.

    Directory of Open Access Journals (Sweden)

    Roger C Young

    2014-10-01

    Full Text Available The mechanisms used to coordinate uterine contractions are not known. We develop a new model based on the proposal that there is a maximum distance to which action potentials can propagate in the uterine wall. This establishes "regions", where one action potential burst can rapidly recruit all the tissue. Regions are recruited into an organ-level contraction via a stretch-initiated contraction mechanism (myometrial myogenic response. Each uterine contraction begins with a regional contraction, which slightly increases intrauterine pressure. Higher pressure raises tension throughout the uterine wall, which initiates contractions of more regions and further increases pressure. The positive feedback synchronizes regional contractions into an organ-level contraction. Cellular automaton (CA simulations are performed with Mathematica. Each "cell" is a region that is assigned an action potential threshold. An anatomy sensitivity factor converts intrauterine pressure to regional tension through the Law of Laplace. A regional contraction occurs when regional tension exceeds regional threshold. Other input variables are: starting and minimum pressure, burst and refractory period durations, enhanced contractile activity during an electrical burst, and reduced activity during the refractory period. Complex patterns of pressure development are seen that mimic the contraction patterns observed in laboring women. Emergent behavior is observed, including global synchronization, multiple pace making regions, and system memory of prior conditions. The complex effects of nifedipine and oxytocin exposure are simulated. The force produced can vary as a nonlinear function of the number of regions. The simulation directly links tissue-level physiology to human labor. The concept of a uterine pacemaker is re-evaluated because pace making activity may occur well before expression of a contraction. We propose a new classification system for biological CAs that parallels

  11. Tactile length contraction as Bayesian inference.

    Science.gov (United States)

    Tong, Jonathan; Ngo, Vy; Goldreich, Daniel

    2016-08-01

    To perceive, the brain must interpret stimulus-evoked neural activity. This is challenging: The stochastic nature of the neural response renders its interpretation inherently uncertain. Perception would be optimized if the brain used Bayesian inference to interpret inputs in light of expectations derived from experience. Bayesian inference would improve perception on average but cause illusions when stimuli violate expectation. Intriguingly, tactile, auditory, and visual perception are all prone to length contraction illusions, characterized by the dramatic underestimation of the distance between punctate stimuli delivered in rapid succession; the origin of these illusions has been mysterious. We previously proposed that length contraction illusions occur because the brain interprets punctate stimulus sequences using Bayesian inference with a low-velocity expectation. A novel prediction of our Bayesian observer model is that length contraction should intensify if stimuli are made more difficult to localize. Here we report a tactile psychophysical study that tested this prediction. Twenty humans compared two distances on the forearm: a fixed reference distance defined by two taps with 1-s temporal separation and an adjustable comparison distance defined by two taps with temporal separation t ≤ 1 s. We observed significant length contraction: As t was decreased, participants perceived the two distances as equal only when the comparison distance was made progressively greater than the reference distance. Furthermore, the use of weaker taps significantly enhanced participants' length contraction. These findings confirm the model's predictions, supporting the view that the spatiotemporal percept is a best estimate resulting from a Bayesian inference process.

    We revisit the notion of possible relativity or kinematic symmetries mutually connected through Lie algebra contractions under a new perspective on what constitutes a relativity symmetry. Contractions of an SO(m,n) symmetry as an isometry on an m+n dimensional geometric arena which generalizes the notion of spacetime are discussed systematically. One of the key results is five different contractions of a Galilean-type symmetry G(m,n) preserving a symmetry of the same type at dimension m+n−1, e.g. a G(m,n−1), together with the coset space representations that correspond to the usual physical picture. Most of the results are explicitly illustrated through the example of symmetries obtained from the contraction of SO(2,4), which is the particular case for our interest on the physics side as the proposed relativity symmetry for “quantum spacetime”. The contractions from G(1,3) may be relevant to real physics.

    European Contract Law is still very much in development. So far, only piecemeal legislation on contract law has been enacted on a European level. Accordingly, many of the questions concerning which rules to decide on are still up for debate. One such debate concerns weaker party protection and more

    Different types of rested-state contractions were examined under the influence of various inotropic agents. In magnesium-free solution, in low sodium (40 mmol/l) solution or in the presence of dihydroouabain, an "early" rested-state contraction developed without delay after stimulation. A distinctive "late" rested-state contraction was observed under the influence of noradrenaline. It is characterized by a latent period of about 100 ms between stimulation and onset of contraction. This latency was not reduced by increasing the catecholamine concentration, despite a concentration-dependent increase in the height of the "late" rested-state contraction. The late rested-state contraction under the influence of noradrenaline was suppressed by the slow inward current inhibitor nifedipine whether or not the nifedipine-dependent shortening of the action potential duration was prevented by caesium. When the slow inward current was not inhibited, the prolongation of the action potential duration by caesium resulted in an increase of the late rested-state contraction because of a prolongation of the time to peak force. High concentrations of dihydroouabain led to the appearance of an early contraction component without appreciably influencing the noradrenaline-dependent late component. From this it was deduced that the activator calcium for the late rested-state contraction was not stored intracellularly during rest prior to stimulation and, consequently, could not have been released by inflowing calcium. Instead, it is proposed that the activator calcium for the late rested-state contraction entered the sites of the sarcoplasmic reticulum and subsequently released from its release sites as long as the cell was depolarized. The "early" rested-state contractions in Mg2+-free solution, in low sodium solution or in the presence of dihydroouabain were not influenced in their contraction velocity by high concentrations of nifedipine which fully inhibited the late rested

    1. Glucose uptake and transport, muscle glycogen, free glucose and glucose-6-phosphate concentrations were studied in perfused resting and contracting rat skeletal muscle with different pre-contraction glycogen concentrations. Rats were pre-conditioned by a combination of swimming exercise and diet......, resulting in either low (glycogen-depleted rats), normal (control rats) or high (supercompensated rats) muscle glycogen concentrations at the time their hindlimbs were perfused. 2. Compared with control rats, pre-contraction muscle glycogen concentration was approximately 40% lower in glycogen-depleted rats......, whereas it was 40% higher in supercompensated rats. Muscle glycogen break-down correlated positively (r = 0.76; P less than 0.001) with pre-contraction muscle glycogen concentration. 3. Glucose uptake during contractions was approximately 50% higher in glycogen-depleted hindquarters than in control...

    In this study, new techniques for approximating the contractile properties of cells in biohybrid devices using Finite Element Analysis (FEA) have been investigated. Many current techniques for modeling biohybrid devices use individual cell forces to simulate the cellular contraction. However, such techniques result in long simulation runtimes. In this study we investigated the effect of the use of thermal contraction on simulation runtime. The thermal contraction model was significantly faster than models using individual cell forces, making it beneficial for rapidly designing or optimizing devices. Three techniques, Stoney׳s Approximation, a Modified Stoney׳s Approximation, and a Thermostat Model, were explored for calibrating thermal expansion/contraction parameters (TECPs) needed to simulate cellular contraction using thermal contraction. The TECP values were calibrated by using published data on the deflections of muscular thin films (MTFs). Using these techniques, TECP values that suitably approximate experimental deflections can be determined by using experimental data obtained from cardiomyocyte MTFs. Furthermore, a sensitivity analysis was performed in order to investigate the contribution of individual variables, such as elastic modulus and layer thickness, to the final calibrated TECP for each calibration technique. Additionally, the TECP values are applicable to other types of biohybrid devices. Two non-MTF models were simulated based on devices reported in the existing literature.
