    Full Text Available To expose cortical involvement in age-related changes in motor performance, we compared steadiness (force fluctuations and fatigability of submaximal isometric contractions with the ankle dorsiflexor muscles in older and young adults and with varying levels of cognitive demand imposed. Sixteen young (20 ± 2 yr: 8 men, 8 women and 17 older adults (69 ±4 yr: 9 men, 8 women attended three sessions and performed a 40 s isometric contraction at 5% maximal voluntary contraction (MVC force followed by an isometric contraction at 30% MVC until task failure. The cognitive demand required during the submaximal contractions in each session differed as follows: 1 high-cognitive demand session where difficult mental math was imposed (counting backward by 13 from a 4-digit number; 2 low-cognitive demand session which involved simple mental math (counting backward by one; and 3 control session with no mental math. Anxiety was elevated during the high-cognitive demand session compared with other sessions for both age groups but more so for the older adults than young adults (p0.05, but the variability between sessions (standard deviation [SD] of 3 sessions was greater for older adults than young (2.02 ± 1.05 min vs. 1.25 ± 0.51 min, P<0.05. Thus, variability in lower limb motor performance for low and moderate force isometric tasks increased with age and was exacerbated when cognitive demand was imposed, and may be related to modulation of synergist and antagonist muscles and an altered neural strategy with age originating from central sources. These data have significant implications for cognitively demanding low-force motor tasks that are relevant to functional and ergonomic in an aging workforce.

    Inonu-Wigner contractions from the rotation group O (n + 1) to the Euclidean group E (n) are used to relate the separation of variables in Laplace-Beltrami operators on n-dimensional spheres and Euclidean spaces. We consider all subgroup type coordinates corresponding to different chains of subgroups of O (n + 1) and E (n). In particular, the contractions relate the graphical formalism of 'trees' on spheres to the 'clusters' on Euclidean spaces (introduced in this article). The contractions are considered analytically on several levels: the vector fields realizing the Lie algebras, the complete sets of commuting operators characterizing separable coordinate systems, the coordinate systems themselves and the separated eigenfunctions

    NASA-SCAR (AST) program was initiated in 1972 at the direct request of the Executive Office of the White House and Congress following termination of the U.S. SST program. The purpose of SCR was to conduct a focused research and technology program on those technology programs which contributed to the SST termination and, also, to provide an expanded data base for future civil and military supersonic transport aircraft. Funding for the Supersonic Cruise Research (SCR) Program was initiated in fiscal year 1973 and terminated in fiscal year 1981. The program was implemented through contracts and grants with industry, universities, and by in-house investigations at the NASA/OAST centers. The studies included system studies and five disciplines: propulsion, stratospheric emissions impact, materials and structures, aerodynamic performance, and stability and control. The NASA/Lewis Variable-Cycle Engine (VCE) Component Program was initiated in 1976 to augment the SCR program in the area of propulsion. After about 2 years, the title was changed to VCE Technology program. The total number of contractors and grantees on record at the AST office in 1982 was 101 for SCR and 4 for VCE. This paper presents a compilation of all the contracts and grants as well as the funding summaries for both programs.

    This report consists of two abstracts submitted for possible presentation at the AIAA Aerospace Science Meeting to be held in January 2005. Since the submittal of these abstracts we are continuing refinement of the model coefficients derived for the case of a variable Turbulent Prandtl number. The test cases being investigated are a Mach 9.2 flow over a degree ramp and a Mach 8.2 3-D calculation of crossing shocks. We have developed an axisymmetric code for treating axisymmetric flows. In addition the variable Schmidt number formulation was incorporated in the code and we are in the process of determining the model constants.

  12. The effects of hospitals' governance on optimal contracts: bargaining vs. contracting.

    Science.gov (United States)

    Galizzi, Matteo M; Miraldo, Marisa

    2011-03-01

    We propose a two-stage model to study the impact of different hospitals' governance frameworks on the optimal contracts designed by third-party payers when patients' disease severity is the private information of the hospital. In the second stage, doctors and managers interact within either a bargaining or a contracting scenario. In the contracting scenario, managers offer a contract that determines the payment to doctors, and doctors decide how many patients to treat. In the bargaining scenario, doctors and managers strategically negotiate on both the payment to doctors and the number of patients to treat. We derive the equilibrium doctors' payments and number of treated patients under both scenarios. We then derive the optimal contract offered by the government to the hospital in the first stage. Results show that when the cost of capital is sufficiently low, the informational rent is lower, and the social welfare is higher, in the contracting scenario. Copyright © 2010 Elsevier B.V.

  14. Why radiologists lose their hospital contracts: is your contract secure?

    Muroff, Lawrence R

    2010-03-01

    Previously, a hospital contract meant tenure for the incumbent group of radiologists; however, those days are long gone. Exclusive contracts have morphed into exclusive contracts with carve-outs. Turf erosion has become a fact of life for radiology practices. Now radiologists are losing their hospital contracts in record numbers. Group size, though helpful for a variety of reasons, does not ensure that a practice will be secure in its hospital setting. The reasons that groups lose their hospital contracts are varied, and in this paper, the author discusses the most common ones. Suggestions to help practices avoid this unfortunate fate are presented.

    2016-02-01

    Full Text Available The concept of permanent-magnet variable-period undulator (VPU was proposed several years ago and has found few implementations so far. The VPUs have some advantages as compared with conventional undulators, e.g., a wider range of radiation wavelength tuning and the option to increase the number of poles for shorter periods. Both these advantages will be realized in the VPU under development now at Budker INP. In this paper, we present the results of 2D and 3D magnetic field simulations and discuss some design features of this VPU.

  18. Observer variability in estimating numbers: An experiment

    1982-01-01

    Census estimates of bird populations provide an essential framework for a host of research and management questions. However, with some exceptions, the reliability of numerical estimates and the factors influencing them have received insufficient attention. Independent of the problems associated with habitat type, weather conditions, cryptic coloration, ete., estimates may vary widely due only to intrinsic differences in observers? abilities to estimate numbers. Lessons learned in the field of perceptual psychology may be usefully applied to 'real world' problems in field ornithology. Based largely on dot discrimination tests in the laboratory, it was found that numerical abundance, density of objects, spatial configuration, color, background, and other variables influence individual accuracy in estimating numbers. The primary purpose of the present experiment was to assess the effects of observer, prior experience, and numerical range on accuracy in estimating numbers of waterfowl from black-and-white photographs. By using photographs of animals rather than black dots, I felt the results could be applied more meaningfully to field situations. Further, reinforcement was provided throughout some experiments to examine the influence of training on accuracy.

  19. Role of updraft velocity in temporal variability of global cloud hydrometeor number

    Sullivan, Sylvia C.; Lee, Dongmin; Oreopoulos, Lazaros; Nenes, Athanasios

    2016-05-01

    Understanding how dynamical and aerosol inputs affect the temporal variability of hydrometeor formation in climate models will help to explain sources of model diversity in cloud forcing, to provide robust comparisons with data, and, ultimately, to reduce the uncertainty in estimates of the aerosol indirect effect. This variability attribution can be done at various spatial and temporal resolutions with metrics derived from online adjoint sensitivities of droplet and crystal number to relevant inputs. Such metrics are defined and calculated from simulations using the NASA Goddard Earth Observing System Model, Version 5 (GEOS-5) and the National Center for Atmospheric Research Community Atmosphere Model Version 5.1 (CAM5.1). Input updraft velocity fluctuations can explain as much as 48% of temporal variability in output ice crystal number and 61% in droplet number in GEOS-5 and up to 89% of temporal variability in output ice crystal number in CAM5.1. In both models, this vertical velocity attribution depends strongly on altitude. Despite its importance for hydrometeor formation, simulated vertical velocity distributions are rarely evaluated against observations due to the sparsity of relevant data. Coordinated effort by the atmospheric community to develop more consistent, observationally based updraft treatments will help to close this knowledge gap.

  20. Pacta sunt servanda versus the social role of contracts: the case of Brazilian agriculture contracts

    Directory of Open Access Journals (Sweden)

    Christiane Leles Rezende

    2012-06-01

    Full Text Available This study explores the instability created by contradictory court decisions related with contract breaches. Forward marketing contracts represent an important source of resources to finance Brazilian agriculture, however a large number of contract breaches were observed during a period of marked increase in soy prices. The study analyzed 161 judicial appeal decisions and a survey was carried with 70 farmers. The results show the difference of judges' interpretation and the existence of second order effects. The effects of court decisions were more requirements of guarantees and the reduction in the number of contracts. Those soybean farmers who did not breach their contracts have also been negatively affected by the strategic reactions of trading and processing companies. The concept of "social function of the contract" introduced in Brazilian civil code led to a higher degree of instability in contracts, raising transaction costs and motivating private economic sanctions.

  1. Conformal maps and group contractions in nuclear structure

    International Nuclear Information System (INIS)

    Bonatsos, D.

    2011-01-01

    In mathematics, a conformal map is a function which preserves angles. We show how this procedure can be used in the framework of the Bohr Hamiltonian, leading to a Hamiltonian in a curved space, in which the mass depends on the nuclear deformation β, while it remains independent of the collective variable γ and the three Euler angles. This Hamiltonian is proved to be equivalent to that obtained using techniques of Supersymmetric Quantum Mechanics. Group contraction is a procedure in which a symmetry group is reduced into a group of lower symmetry in a certain limiting case. Examples are provided in the large boson number limit of the Interacting Boson Approximation (IBA) model by a) the contraction of the SU(3) algebra into the [R 5 ]SO(3) algebra of the rigid rotator, consisting of the angular momentum operators forming SO(3), plus 5 mutually commuting quantities, the quadrupole operators, b) the contraction of the O(6) algebra into the [R 5 ]SO(5) algebra of the γ-unstable rotator. We show how contractions can be used for constructing symmetry lines in the interior of the symmetry triangle of the IBA model. (author)

  2. Improving the repeatability of Motor Unit Number Index (MUNIX) by introducing additional epochs at low contraction levels.

    Peng, Yun; Zhang, Yingchun

    2017-07-01

    To evaluate the repeatability of (Motor Unit Number Index) MUNIX under repeatability conditions, specify the origin of variations and provide strategies for quality control. MUNIX calculations were performed on the bicep brachii muscles of eight healthy subjects. Negative effect of suboptimal electrode positions on MUNIX accuracy was eliminated by employing the high-density surface electromyography technique. MUNIX procedures that utilized a variety of surface interferential pattern (SIP) epoch recruitment strategies (including the original MUNIX procedure, two proposed improvement strategies and their combinations) were described. For each MUNIX procedure, ten thousands of different SIP pools were constructed by randomly recruiting necessary SIP epochs from a large SIP epoch pool (3 datasets, 9 independent electromyography recordings at different contraction levels per dataset and 10 SIP epochs per recording) and implemented for MUNIX calculation. The repeatability of each MUNIX procedure was assessed by summarizing the resulting MUNIX distribution and compared to investigate the effect of SIP epoch selection strategy on repeatability performance. SIP epochs selected at lower contraction levels have a stronger influence on the repeatability of MUNIX than those selected at higher contraction levels. MUNIX under repeatability conditions follows a normal distribution and the standard deviation can be significantly reduced by introducing more epochs near the MUNIX definition line. The MUNIX technique shows an inherent variation attributable to SIP epochs at low contraction levels. It is recommended that more epochs should be sampled at these low contraction levels to improve the repeatability. The present study thoroughly documented the inherent variation of MUNIX and the causes, and offered practical solutions to improve the repeatability of MUNIX.

  6. The role of updraft velocity in temporal variability of cloud hydrometeor number

    Science.gov (United States)

    2016-04-01

    Significant effort has been dedicated to incorporating direct aerosol-cloud links, through parameterization of liquid droplet activation and ice crystal nucleation, within climate models. This significant accomplishment has generated the need for understanding which parameters affecting hydrometer formation drives its variability in coupled climate simulations, as it provides the basis for optimal parameter estimation as well as robust comparison with data, and other models. Sensitivity analysis alone does not address this issue, given that the importance of each parameter for hydrometer formation depends on its variance and sensitivity. To address the above issue, we develop and use a series of attribution metrics defined with adjoint sensitivities to attribute the temporal variability in droplet and crystal number to important aerosol and dynamical parameters. This attribution analysis is done both for the NASA Global Modeling and Assimilation Office Goddard Earth Observing System Model, Version 5 and the National Center for Atmospheric Research Community Atmosphere Model Version 5.1. Within the GEOS simulation, up to 48% of temporal variability in output ice crystal number and 61% in droplet number can be attributed to input updraft velocity fluctuations, while for the CAM simulation, they explain as much as 89% of the ice crystal number variability. This above results suggest that vertical velocity in both model frameworks is seen to be a very important (or dominant) driver of hydrometer variability. Yet, observations of vertical velocity are seldomly available (or used) to evaluate the vertical velocities in simulations; this strikingly contrasts the amount and quality of data available for aerosol-related parameters. Consequentially, there is a strong need for retrievals or measurements of vertical velocity for addressing this important knowledge gap that requires a significant investment and effort by the atmospheric community. The attribution metrics as a

  8. The number of subjects per variable required in linear regression analyses.

    Science.gov (United States)

    Austin, Peter C; Steyerberg, Ewout W

    2015-06-01

    To determine the number of independent variables that can be included in a linear regression model. We used a series of Monte Carlo simulations to examine the impact of the number of subjects per variable (SPV) on the accuracy of estimated regression coefficients and standard errors, on the empirical coverage of estimated confidence intervals, and on the accuracy of the estimated R(2) of the fitted model. A minimum of approximately two SPV tended to result in estimation of regression coefficients with relative bias of less than 10%. Furthermore, with this minimum number of SPV, the standard errors of the regression coefficients were accurately estimated and estimated confidence intervals had approximately the advertised coverage rates. A much higher number of SPV were necessary to minimize bias in estimating the model R(2), although adjusted R(2) estimates behaved well. The bias in estimating the model R(2) statistic was inversely proportional to the magnitude of the proportion of variation explained by the population regression model. Linear regression models require only two SPV for adequate estimation of regression coefficients, standard errors, and confidence intervals. Copyright © 2015 The Authors. Published by Elsevier Inc.

  9. Determinants of the number of bidders in the competitive procurement of electricity supply contracts in the Japanese public sector

    International Nuclear Information System (INIS)

    Hattori, Toru

    2010-01-01

    Since the electricity retail market in Japan was partially opened to competition in 2000, many government entities have sought to solicit competing bids for the electricity supply to their office buildings or facilities, encouraging competition between the incumbents and new entrants. However, in many cases, only the incumbent utility bids for the contract and the competitive effects are limited. This paper presents a statistical analysis of bidders' participation in competitive procurement. We employ several count data regression models to explain the number of bidders other than the local electric utility. Our results suggest that the number of bidders would decrease in response to an increase in the load factor, perhaps because the new entrants are less competitive in serving customers with high load factors as they do not operate low-cost base-load power plants such as nuclear power plants; It would increase along with the voltage level and contract demand. The results also indicate that new entrants are more likely to participate in the bidding process in large city areas. (author)

  10. Dynamic Expansion and Contraction of cagA Copy Number in Helicobacter pylori Impact Development of Gastric Disease

    Directory of Open Access Journals (Sweden)

    Sungil Jang

    2017-02-01

    Full Text Available Infection with Helicobacter pylori is a major risk factor for development of gastric disease, including gastric cancer. Patients infected with H. pylori strains that express CagA are at even greater risk of gastric carcinoma. Given the importance of CagA, this report describes a new molecular mechanism by which the cagA copy number dynamically expands and contracts in H. pylori. Analysis of strain PMSS1 revealed a heterogeneous population in terms of numbers of cagA copies; strains carried from zero to four copies of cagA that were arranged as direct repeats within the chromosome. Each of the multiple copies of cagA was expressed and encoded functional CagA; strains with more cagA repeats exhibited higher levels of CagA expression and increased levels of delivery and phosphorylation of CagA within host cells. This concomitantly resulted in more virulent phenotypes as measured by cell elongation and interleukin-8 (IL-8 induction. Sequence analysis of the repeat region revealed three cagA homologous areas (CHAs within the cagA repeats. Of these, CHA-ud flanked each of the cagA copies and is likely important for the dynamic variation of cagA copy numbers. Analysis of a large panel of clinical isolates showed that 7.5% of H. pylori strains isolated in the United States harbored multiple cagA repeats, while none of the tested Korean isolates carried more than one copy of cagA. Finally, H. pylori strains carrying multiple cagA copies were differentially associated with gastric disease. Thus, the dynamic expansion and contraction of cagA copy numbers may serve as a novel mechanism by which H. pylori modulates gastric disease development.

  11. The Relationship between the Employment Contract and other Civil Contracts

    Directory of Open Access Journals (Sweden)

    Răzvan Radu Popescu

    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.

    Osmundsen, Petter; Sorenes, Terje; Toft, Anders

    2008-01-01

    Shortages of rigs and personnel have encouraged discussion of designing incentive contracts in the drilling sector. However, for the drilling contracts, there are not a large variety of contract types in use. This article describes and analyses incentives for drilling contractors. These are directly represented by the compensation formats utilised in the present and in the consecutive drilling contracts. Indirectly, incentives are also provided by the evaluation criteria that oil companies use for awarding drilling assignments. Changes in contract format pose a number of relevant questions relating to resource management, and the article takes an in-depth look at some of these. Do evaluation criteria for awarding drilling assignments encourage the development of new technology and solutions? How will a stronger focus on drilling efficiency influence reservoir utilisation?

  15. 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...

  16. Understanding Cirrus Ice Crystal Number Variability for Different Heterogeneous Ice Nucleation Spectra

    Along with minimizing parameter uncertainty, understanding the cause of temporal and spatial variability of the nucleated ice crystal number, Ni, is key to improving the representation of cirrus clouds in climate models. To this end, sensitivities of Ni to input variables like aerosol number and diameter provide valuable information about nucleation regime and efficiency for a given model formulation. Here we use the adjoint model of the adjoint of a cirrus formation parameterization (Barahona and Nenes, 2009b) to understand Ni variability for various ice-nucleating particle (INP) spectra. Inputs are generated with the Community Atmosphere Model version 5, and simulations are done with a theoretically derived spectrum, an empirical lab-based spectrum and two field-based empirical spectra that differ in the nucleation threshold for black carbon particles and in the active site density for dust. The magnitude and sign of Ni sensitivity to insoluble aerosol number can be directly linked to nucleation regime and efficiency of various INP. The lab-based spectrum calculates much higher INP efficiencies than field-based ones, which reveals a disparity in aerosol surface properties. Ni sensitivity to temperature tends to be low, due to the compensating effects of temperature on INP spectrum parameters; this low temperature sensitivity regime has been experimentally reported before but never deconstructed as done here.

  17. Evaluation of the value of availability and dispatchability in IPP contracts

    Consolidated Edison's resource plan relies on power from Independent Power Producers (IPPs) for a portion of future generation requirements. The additional restriction of obtaining this capacity through a bidding process requires the utility to evaluate a large number of potential contracts with different combinations of price, availability, and dispatchability. This paper discusses the theoretical considerations and outlines the methodology adopted for Consolidated Edison's first request for proposal. The value of an IPP contract is a function of the variable energy cost compared to the system avoided costs. For example, there is a value for availability only in those hours when contract cost is below the avoided cost and there is a penalty for non-dispatchability only in those hours when the contract cost is higher than the avoided cost. The best method to determine the value of an IPP contract would be to simulate the operation of the system with and without the IPP purchase using a perfect production cost model. In reality no model is perfect and there are trade-offs because not all aspects of system operation are captured. Performing a detailed production cost simulation for every proposal would be burdensome. Therefore, it was decided that a simplified methodology was needed. An additional benefit of a simplified approach is that the IPPs could score their own proposals and use this value as input into their final pricing scheme. The method developed relies on detailed production cost simulations to generate hourly avoided costs. A comparison of these avoided costs to the IPP variable costs becomes the basis for the calculation of the value of availability or dispatchability. This methodology can be applied consistently to all supply side resources; baseload or peaking, gas, oil or coal fired. This allows for the evaluation of all bid proposals on an equal basis

    A remarkable equivalence is established between the theories of spinning particles or superparticles using anticommuting Grassmann variables on the one hand and commuting c-number spinors on the other. We consider both real and complex Grassmann variables and map the equations of motion and the supersymmetry transformation from one theory to another. The more intuitive c-number theory allows us to generalize the notion of Zitterbewegung to strings and membranes. (A hidden supersymmetry exists in the classical model of the Dirac electron.)

  19. Choreography Synthesis as Contract Agreement

    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.

    This research explores the relationship between political campaign contributions, lobbying and post-Hurricane Katrina cleanup and reconstruction contracts. Specifically, a case-control study design is used to determine whether campaign contributions to national candidates in the 2000-04 election cycles and/or the employment of lobbyists and lobbying firms increased a company's probability of receiving a post-hurricane contract. Results indicate that both a campaign contribution dichotomous variable and the dollar amount of contributions are significantly related to whether a company received a contract, but that lobbying activity was not. These findings are discussed in the context of previous research on the politics of natural disasters, government contracting and governmental and corporate deviance.

    Full Text Available Mergers and acquisitions (M-A affect the psychological contract of employees. This study assessed the impact of the M-A on survivors’ psychological contract, job satisfaction, organizational commitment, turnover intention, and whether credible explanation moderated employees’ reactions. Statistical analyses were performed on data gathered from 196 respondents of two pharmaceuticals in Puerto Rico. Results revealed an inverse correlation between perceived psychological contract violation (PCV and the variables job satisfaction and organizational commitment. They also confirmed the direct correlation between PCV and the variable turnover intention. This study found an effect of the moderating variable credible explanation on the variables job satisfaction and organizational commitment. An understanding of psychological contract theory may reduce the perceived violation and its impact on employees’ attitudes.

    Variability in premature ventricular contraction (PVC) coupling interval (CI) increases the risk of cardiomyopathy and sudden death. The autonomic nervous system regulates cardiac electrical and mechanical indices, and its dysregulation plays an important role in cardiac disease pathogenesis. The impact of PVCs on the intrinsic cardiac nervous system, a neural network on the heart, remains unknown. The objective was to determine the effect of PVCs and CI on intrinsic cardiac nervous system function in generating cardiac neuronal and electric instability using a novel cardioneural mapping approach. In a porcine model (n=8), neuronal activity was recorded from a ventricular ganglion using a microelectrode array, and cardiac electrophysiological mapping was performed. Neurons were functionally classified based on their response to afferent and efferent cardiovascular stimuli, with neurons that responded to both defined as convergent (local reflex processors). Dynamic changes in neuronal activity were then evaluated in response to right ventricular outflow tract PVCs with fixed short, fixed long, and variable CI. PVC delivery elicited a greater neuronal response than all other stimuli ( P <0.001). Compared with fixed short and long CI, PVCs with variable CI had a greater impact on neuronal response ( P <0.05 versus short CI), particularly on convergent neurons ( P <0.05), as well as neurons receiving sympathetic ( P <0.05) and parasympathetic input ( P <0.05). The greatest cardiac electric instability was also observed after variable (short) CI PVCs. Variable CI PVCs affect critical populations of intrinsic cardiac nervous system neurons and alter cardiac repolarization. These changes may be critical for arrhythmogenesis and remodeling, leading to cardiomyopathy. © 2017 American Heart Association, Inc.

  10. Motor Unit Interpulse Intervals During High Force Contractions.

    Stock, Matt S; Thompson, Brennan J

    2016-01-01

    We examined the means, medians, and variability for motor-unit interpulse intervals (IPIs) during voluntary, high force contractions. Eight men (mean age = 22 years) attempted to perform isometric contractions at 90% of their maximal voluntary contraction force while bipolar surface electromyographic (EMG) signals were detected from the vastus lateralis and vastus medialis muscles. Surface EMG signal decomposition was used to determine the recruitment thresholds and IPIs of motor units that demonstrated accuracy levels ≥ 96.0%. Motor units with high recruitment thresholds demonstrated longer mean IPIs, but the coefficients of variation were similar across all recruitment thresholds. Polynomial regression analyses indicated that for both muscles, the relationship between the means and standard deviations of the IPIs was linear. The majority of IPI histograms were positively skewed. Although low-threshold motor units were associated with shorter IPIs, the variability among motor units with differing recruitment thresholds was comparable.

  11. Controls on the meridional extent of tropical precipitation and its contraction under global warming

    Donohoe, A.

    2017-12-01

    A method for decomposing changes and variability in the spatial structure of tropical precipitation into shifting (meridional translation), contracting, and intensifying modes of variability is introduced. We demonstrate that the shifting mode of tropical precipitation explains very little (20%) more of the tropical precipitation changes and variability. Furthermore, the contraction of tropical precipitation is highly correlated (R2 > 0.95) with an intensification of the precipitation in both the observations and forced modeled simulations. These results suggest that the simultaneous contraction and intensification of tropical precipitation is the dominant mode of variability and changes under external forcing. We speculate that tropical surface temperature controls this concurrent variability. Indeed, models robustly predict that tropical precipitation increases and meridionally contracts in response to increased CO2 and is reduced and meridionally expanded under glacial forcing and boundary conditions. In contrast, the directionality of the tropical precipitation shift is both ambiguous and small in magnitude in response to increased CO2. Furthermore, the ratio of the contraction/expansion to intensification/reduction is consistent in the continuum of climate states from the glacial climate to a modern climate to a 4XCO2 climate suggesting that the intensification and contraction are linked together via a single mechanism. We examine two mechanisms responsible for the contraction of the precipitation under global warming : i. the reduction of the seasonal cycle of energy input to the atmosphere due to sea ice retreat that results in the tropical precipitation remaining closer to the equator during the solsticial seasons and; ii. the increased gross moist stability of the tropical atmosphere as the surface warms resulting in a weaker cross-equatorial Hadley circulation during the solsticial seasons.

    Utilization of high-intensity resistance training to counter age-related sarcopenia is currently debated because of the potential for maladaptation when training design is inappropriate. Training design is problematic because the influence of various loading variables (e.g. contraction mode, repetition number, and training frequency) is still not well characterized at old age. To address this in a precisely controlled manner, we developed a rodent model of high-intensity training consisting of maximally-activated stretch-shortening contractions (SSCs), contractions typical during resistance training. With this model, we determined that at old age, high-repetition SSC training (80 SSCs: 8 sets of 10 repetitions) performed frequently (i.e. 3 days per week) for 4.5 weeks induced strength deficits with no muscle mass gain while decreasing frequency to 2 days per week promoted increases in muscle mass and muscle quality (i.e. performance normalized to muscle mass). This finding confirmed the popular notion that decreasing training frequency has a robust effect with age. Meanwhile, the influence of other loading variables remains contentious. The aim of the present study was to assess muscle adaptation following modulation of contraction mode and repetition number during high-intensity SSC training. Muscles of young (3 month old) and old (30 month old) male rats were exposed to 4.5 weeks of low-repetition static training of 4 (i.e. 4 sets of one repetition) isometric (ISO) contractions 3 days per week or a more moderate-repetition dynamic training of 40 SSCs (i.e. 4 sets of 10 repetitions) 3 days per week. For young rats, performance and muscle mass increased regardless of training protocol. For old rats, no muscle mass adaptation was observed for 4 ISO training while 40 SSC training induced muscle mass gain without improvement in muscle quality, an outcome distinct from modulating training frequency. Muscle mass gain for old rats was accompanied by

    General theorems are given for SU(n) and SO(n). A projective geometry argument is also presented with disclosure of the occurrence a group contraction mechanism as a geometric consequence of spontaneous breakdown of symmetry. It is also shown that a contraction of the conformal group gives account of the number of degrees of freedom of an n-pseudoparticle system in an Euclidean SU(2) gauge invariant Yang-Mills theory, in agreement with the result obtained by algebraic geometry methods. Low-energy theorems and ordered states symmetry patterns are observable manifestations of group contractions. These results seem to support the conjecture that the transition from quantum to classical physics involves a group contraction mechanism. (author)

    Full Text Available This study aims to examine the franchise sector and determine the significant factors that contribute to an increase in the number of franchiser’s contracts in Turkey. Secondary data is used from the Turkish Franchise Association and multivariate regression models are run for each sector. Our models explain the change in the number of franchise contracts with R2’s varying between .6577 and .7549. We provide evidence that success factors in increasing the number of contracts change depending on the sector firms operating in and contracts may be designed thusly to pursue success.

  17. A Variable Turbulent Schmidt Number Formulation for Scramjet Application

    2004-01-01

    In high speed engines, thorough turbulent mixing of fuel and air is required to obtain high performance and high efficiency. Thus, the ability to predict turbulent mixing is crucial in obtaining accurate numerical simulation of an engine and its performance. Current state of the art in CFD simulation is to assume both turbulent Prandtl number and Schmidt numbers to be constants. However, since the mixing of fuel and air is inversely proportional to the Schmidt number, a value of 0.45 for the Schmidt number will produce twice as much diffusion as that with a value of 0.9. Because of this, current CFD tools and models have not been able to provide the needed guidance required for the efficient design of a scramjet engine. The goal of this investigation is to develop the framework needed to calculate turbulent Prandtl and Schmidt numbers as part of the solution. This requires four additional equations: two for the temperature variance and its dissipation rate and two for the concentration variance and its dissipation rate. In the current investigation emphasis will be placed on studying mixing without reactions. For such flows, variable Prandtl number does not play a major role in determining the flow. This, however, will have to be addressed when combustion is present. The approach to be used is similar to that used to develop the k-zeta model. In this approach, relevant equations are derived from the exact Navier-Stokes equations and each individual correlation is modeled. This ensures that relevant physics is incorporated into the model equations. This task has been accomplished. The final set of equations have no wall or damping functions. Moreover, they are tensorially consistent and Galilean invariant. The derivation of the model equations is rather lengthy and thus will not be incorporated into this abstract, but will be included in the final paper. As a preliminary to formulating the proposed model, the original k-zeta model with constant turbulent Prandtl and

    In risk analysis, Cooke′s classical model for aggregating expert judgment has been widely used for over 20 years. However, the validity of this model has been the subject of much debate. Critics assert that this model′s scoring rule may unintentionally reward experts who manipulate their quantile estimates in order to receive a greater weight. In addition, the question of the number of seed variables required to ensure adequate performance of Cooke′s classical model remains unanswered. In this study, we conduct a comprehensive examination of the model through an iterative, cross validation test to perform an out-of-sample comparison between Cooke′s classical model and the equal-weight linear opinion pool method on almost all of the expert judgment studies compiled by Cooke and colleagues to date. Our results indicate that Cooke′s classical model significantly outperforms equally weighting expert judgment, regardless of the number of seed variables used; however, there may, in fact, be a maximum number of seed variables beyond which Cooke′s model cannot outperform an equally-weighted panel. - Highlights: • We examine Cooke′s classical model through an iterative, cross validation test. • The performance-based and equally weighted decision makers are compared. • Results strengthen Cooke′s argument for a two-fold cross-validation approach. • Accuracy test results show strong support in favor of Cooke′s classical method. • There may be a maximum number of seed variables that ensures model performance

    In order to improve the prediction performance of the numerical simulations for heat transfer of supercritical pressure fluids, a variable turbulent Prandtl number (Prt) model for vertical upward flow at supercritical pressures was developed in this study. The effects of Prt on the numerical simulation were analyzed, especially for the heat transfer deterioration conditions. Based on the analyses, the turbulent Prandtl number was modeled as a function of the turbulent viscosity ratio and molecular Prandtl number. The model was evaluated using experimental heat transfer data of CO2, water and Freon. The wall temperatures, including the heat transfer deterioration cases, were more accurately predicted by this model than by traditional numerical calculations with a constant Prt. By analyzing the predicted results with and without the variable Prt model, it was found that the predicted velocity distribution and turbulent mixing characteristics with the variable Prt model are quite different from that predicted by a constant Prt. When heat transfer deterioration occurs, the radial velocity profile deviates from the log-law profile and the restrained turbulent mixing then leads to the deteriorated heat transfer.

  7. The legality of unilateral increase of interest rate in banking loan contracts under Serbian law

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available The economic crisis spread in 2008 through the world and reached Serbia, rendered the repayment of banking loans indexed in foreign currencies, mostly in CHF at the time, even more difficult. The growing number of non-performing loans inevitably led to an increase in number of the court proceedings in which the debtors made attempts to have the loan contracts declared null and void. In these proceedings, the courts needed to take a stand on some typical clauses in loan contracts and on some banking practices that the debtors considered to be contrary to the principle of good faith, which, before the crisis, was hardly ever given judicial epilogue. In the majority of cases, two types of clauses proved to be unlawful: a clause establishing a right of the bank to subsequently, i.e. after the formation of the contract, and unilaterally, i.e. without a specific consent of the debtor, change (regularly increase the interest rate for the remainder of the credit period; and a clause establishing the right of the bank to apply different exchange rates, i.e. the buying rate to the disbursement of the loan, and the selling rate to the value of credit installments. These clauses certainly existed even before the crisis, but the difficulties in performing the loans caused by the crisis was the social propelling force that brought these cases within the sight of the judiciary. In this paper the author analyzes the reaction of courts, and subsequently that of the legislator, to the clause in loan contracts entitling the bank to unilaterally increase the variable interest rate after the formation of contract. The application of this clause was usually conditioned on significant changes in international financial markets or changes in the costs of the sources of financing, while in some cases the conditions of the application of the clause were simply changes in the business policy of the bank or the need to operate with profit. In any case, these are

    A number of impediments have discouraged federal agencies from using shared energy savings contracts. As of November 30, 1988, only two federal agencies - the U.S. Postal Service (USPS) and the Department of the Army -had awarded such contracts even though they can yield significant energy and cost savings. The three major impediments we identified were uncertainty about the applicability of a particular procurement policy and practice, lack of management incentives, and difficulty in measuring energy and cost savings. To address the first impediment, the Department of Energy (DOE) developed a manual on shared energy savings contracting. The second impediment was addressed when the 100th Congress authorized incentives for federal agencies to enter into shared savings contracts. DOE addressed the third impediment by developing a methodology for calculating energy consumption and cost savings. However, because of differing methodological preferences, this issue will need to be addressed on a contract-by-contract basis. Some state governments and private sector firms are using performance contracts to reduce energy costs in their buildings and facilities. We were able to identify six states that were using performance contracts. Five have established programs, and all six states have projects under contract. The seven energy service companies we contacted indicated interest in federal shared energy savings contracting

    2011-12-01

    We consider a health care system consisting of two noncooperative parties: a health purchaser (payer) and a health provider, where the interaction between the two parties is governed by a payment contract. We determine the contracts that coordinate the health purchaser-health provider relationship; i.e. the contracts that maximize the population's welfare while allowing each entity to optimize its own objective function. We show that under certain conditions (1) when the number of customers for a preventive medical intervention is verifiable, there exists a gate-keeping contract and a set of concave piecewise linear contracts that coordinate the system, and (2) when the number of customers is not verifiable, there exists a contract of bounded linear form and a set of incentive-feasible concave piecewise linear contracts that coordinate the system.

  17. Current problems associated with nuclear plant construction contracts

    Albano, Raffaele.

    1977-01-01

    The expansion of nuclear electricity generating programmes has brought to the fore the problems associated with construction of this type of power plant. The paper analyses the contracts for such construction and describes the most common, the turnkey contract. The present tendency is to limit the scope of turnkey contracts to the nuclear system or simply to the reactor and this is especially common in advanced nuclear countries such as the US, Canada, Japan, UK and France, and this is also the case in Italy where the question of contracting nuclear plants is debated. In Germany the power utilities hold a large number of shares in the manufacturing industry and the turnkey contract is therefore more economically attractive. A detailed description of the contracting procedure is provided, including the suppliers' and purchasers' responsibilities, plant commissioning tests and handing over of the plant to the operator.

    The aim of this study was to evaluate the inter- and intraobserver correlation of the different intrapartum-transperineal-ultrasound-parameters(ITU) (angle of progression (AoP), progression-distance (PD), head-direction (HD), midline-angle (MLA) and head-perineum distance (HPD)) with contraction and pushing. We evaluated 28 nulliparous women at full dilatation under epidural analgesia. We performed a transperineal ultrasound evaluating AoP and PD in the longitudinal plane, and MLA and HPD in the transverse plane. Interclass correlation coefficients (ICC) with 95% CIs and Bland-Altman analysis were used to assess intra- and interobserver measurement's repeatability. The ICC of the ITU for the same observer was adequate for all the parameters (p pushing under epidural analgesia. Impact statement What is already known on this subject: The intrapartum transperineal ultrasound parameters can be used with contraction and pushing under epidural analgesia. What the results of this study add to what we know: ITU may be used to evaluate the difficulty of instrumental delivery/to evaluate the difficulty of instrumentation in vaginal operative deliveries and this study concludes that ITU is reproducible during uterine contraction with pushing. What the implications are of these findings for clinical practice and/or further research: Therefore, ITU could be used without difficulty with an adequate intra- and interobserver correlation for the prediction of instrumentation difficulty in operative vaginal deliveries.

    Complex tensor contraction expressions arise in accurate electronic structure models in quantum chemistry, such as the coupled cluster method. This paper addresses two complementary aspects of performance optimization of such tensor contraction expressions. Transformations using algebraic properties of commutativity and associativity can be used to significantly decrease the number of arithmetic operations required for evaluation of these expressions. The identification of common subexpressions among a set of tensor contraction expressions can result in a reduction of the total number of operations required to evaluate the tensor contractions. The first part of the paper describes an effective algorithm for operation minimization with common subexpression identification and demonstrates its effectiveness on tensor contraction expressions for coupled cluster equations. The second part of the paper highlights the importance of data layout transformation in the optimization of tensor contraction computations on modern processors. A number of considerations such as minimization of cache misses and utilization of multimedia vector instructions are discussed. A library for efficient index permutation of multi-dimensional tensors is described and experimental performance data is provided that demonstrates its effectiveness.

    The maintenance of steady contractions is required in many daily tasks. However, there is little understanding of how various lower limb configurations influence the ability to maintain force. The purpose of the current investigation was to examine the influence of joint angle on various lower-limb constant force contractions. Nineteen adults performed knee extension, knee flexion, and ankle plantarflexion isometric force contractions to 11 target forces, ranging from 2 to 95% maximal voluntary contraction (MVC) at 2 angles. Force variability was quantified with mean force, standard deviation, and the coefficient of variation of force output. Non-linearities in force output were quantified with approximate entropy. Curve fitting analyses were performed on each set of data from each individual across contractions to further examine whether joint angle interacts with global functions of lower-limb force variability. Joint angle had significant effects on the model parameters used to describe the force-variability function for each muscle contraction (p force output were more explained by force level in smaller angle conditions relative to the larger angle conditions (p force production. Biomechanical factors, such as joint angle, along with neurophysiological factors should be considered together in the discussion of the dynamics of constant force production.

  6. Building Information Modelling and Standardised Construction Contracts: a Content Analysis of the GC21 Contract

    2015-08-01

    Full Text Available Building Information Modelling (BIM is seen as a panacea to many of the ills confronting the Architectural, Engineering and Construction (AEC sector. In spite of its well documented benefits the widespread integration of BIM into the project lifecycle is yet to occur. One commonly identified barrier to BIM adoption is the perceived legal risks associated with its integration, coupled with the need for implementation in a collaborative environment. Many existing standardised contracts used in the Australian AEC industry were drafted before the emergence of BIM. As BIM continues to become ingrained in the delivery process the shortcomings of these existing contracts have become apparent. This paper reports on a study that reviewed and consolidated the contractual and legal concerns associated with BIM implementation. The findings of the review were used to conduct a qualitative content analysis of the GC21 2nd edition, an Australian standardised construction contract, to identify possible changes to facilitate the implementation of BIM in a collaborative environment. The findings identified a number of changes including the need to adopt a collaborative contract structure with equitable risk and reward mechanisms, recognition of the model as a contract document and the need for standardisation of communication/information exchange.

    Some concern has arisen about adverse health effects of cell phones, especially the possibility that the low power microwave-frequency signal transmitted by the antennas on handsets might cause brain tumors or accelerate the growth of subclinical tumors. We analyzed data from the Statistical Report: Primary Brain Tumors in the United States, 2000-2004 and 2007 cell phone subscription data from the Governing State and Local Sourcebook. There was a significant correlation between number of cell phone subscriptions and brain tumors in nineteen US states (r = 0.950, P cell phone subscriptions and brain tumors could be due solely to the fact that some states, such as New York, have much larger populations than other states, such as North Dakota, multiple linear regression was performed with number of brain tumors as the dependent variable, cell phone subscriptions, population, mean family income and mean age as independent variables. The effect of cell phone subscriptions was significant (P = 0.017), and independent of the effect of mean family income (P = 0.894), population (P = 0.003) and age (0.499). The very linear relationship between cell phone usage and brain tumor incidence is disturbing and certainly needs further epidemiological evaluation. In the meantime, it would be prudent to limit exposure to all sources of electro-magnetic radiation.

  8. Managing hydroclimatological risk to water supply with option contracts and reservoir index insurance

    Brown, Casey; Carriquiry, Miguel

    2007-11-01

    This paper explores the performance of a system of economic instruments designed to facilitate the reduction of hydroclimatologic variability-induced impacts on stakeholders of shared water supply. The system is composed of bulk water option contracts between urban water suppliers and agricultural users and insurance indexed on reservoir inflows. The insurance is designed to cover the financial needs of the water supplier in situations where the option is likely to be exercised. Insurance provides the irregularly needed funds for exercising the water options. The combined option contract - reservoir index insurance system creates risk sharing between sectors that is currently lacking in many shared water situations. Contracts are designed for a shared agriculture - urban water system in Metro Manila, Philippines, using optimization and Monte Carlo analysis. Observed reservoir inflows are used to simulate contract performance. Results indicate the option - insurance design effectively smooths water supply costs of hydrologic variability for both agriculture and urban water.

    In the present paper the role of the state of the psychological contract to predict psychological health results is studied in a sample of 385 employees of different Spanish companies. Results indicate that the state of the psychological contract significantly predicts life satisfaction, work-family conflict and well-being beyond the prediction produced by the content of the psychological contract. In addition, trust and fairness, two dimensions of the state of psychological contract, all together contribute to explain these psychological health variables adding value to the role as predictor of fulfillment of the psychological contract. The results support the approach argued by Guest and colleagues.

  14. A 'new' psychological contract for nurses: some management implications.

    Science.gov (United States)

    Cavanagh, S J

    1996-03-01

    Changes within the health services are raising a number of employment issues for nurses. The idea that a professional qualification and a job will lead to security of employment and career development is rapidly changing. These assumptions, the 'old' psychological contract, is giving way to new expectations from employers and employees; the emergence of a 'new' psychological contract. A psychological contract is an implicit agreement between employer and employee that each party will treat the other fairly. Such contracts are maintained by virtue of all parties wanting to seek agreement on issues where possible and to maintain trust. While such a contract is not a legally binding agreement it is nonetheless a binding understanding between people. Changes to this psychological contract can have important implications for individuals and their employer in terms of work and organizational commitment. This paper will discuss some of the issues surrounding psychological contracts and the impact of violating them. It will also discuss, from a management perspective, how psychological contracts develop between employer and employee, and how to form a 'new' psychological contract based upon mutual benefit and shared values.

    2017-12-01

    Full Text Available Metamodeling techniques have recently been proposed to address the computational issues related to the valuation of large portfolios of variable annuity contracts. However, it is extremely diffcult, if not impossible, for researchers to obtain real datasets frominsurance companies in order to test their metamodeling techniques on such real datasets and publish the results in academic journals. To facilitate the development and dissemination of research related to the effcient valuation of large variable annuity portfolios, this paper creates a large synthetic portfolio of variable annuity contracts based on the properties of real portfolios of variable annuities and implements a simple Monte Carlo simulation engine for valuing the synthetic portfolio. In addition, this paper presents fair market values and Greeks for the synthetic portfolio of variable annuity contracts that are important quantities for managing the financial risks associated with variable annuities. The resulting datasets can be used by researchers to test and compare the performance of various metamodeling techniques.

    1999-01-01

    Since July 1994, the CERN Civil Engineering group within the ST division has been preparing and engaging contracts related to the Large Hadron Collider (LHC) project. Several of these contracts have values in excess of 10 MCHF and will be executed over a number of years; as such they represent an important part of the infrastructure works required for the LHC. To date, in excess of two hundred and fifty companies have been consulted in relation to these contracts. Contracts or orders have been placed with over thirty companies or joint ventures of companies from nearly all the CERN Member States. This paper aims to show the inter-relationships between these contracts and how the Civil Engineering group is carrying out the management of these important LHC contracts. The organization of the group will be explained along with the roles of individual members within the group.

  19. Contract on using computer resources of another

    Full Text Available Contractual relations involving the use of another's property are quite common. Yet, the use of computer resources of others over the Internet and legal transactions arising thereof certainly diverge from the traditional framework embodied in the special part of contract law dealing with this issue. Modern performance concepts (such as: infrastructure, software or platform as high-tech services are highly unlikely to be described by the terminology derived from Roman law. The overwhelming novelty of high-tech services obscures the disadvantageous position of contracting parties. In most cases, service providers are global multinational companies which tend to secure their own unjustified privileges and gain by providing lengthy and intricate contracts, often comprising a number of legal documents. General terms and conditions in these service provision contracts are further complicated by the '.service level agreement', rules of conduct and (nonconfidentiality guarantees. Without giving the issue a second thought, users easily accept the pre-fabricated offer without reservations, unaware that such a pseudo-gratuitous contract actually conceals a highly lucrative and mutually binding agreement. The author examines the extent to which the legal provisions governing sale of goods and services, lease, loan and commodatum may apply to 'cloud computing' contracts, and analyses the scope and advantages of contractual consumer protection, as a relatively new area in contract law. The termination of a service contract between the provider and the user features specific post-contractual obligations which are inherent to an online environment.

  20. Greening Public Buildings: ESCO-Contracting in Danish Municipalities

    2013-05-01

    Full Text Available This paper presents current research on Danish municipalities’ use of Energy Service Companies (ESCO as a way to improve the standard of public buildings and to increase energy efficiency. In recent years more and more municipalities have used ESCO-contracts to retrofit existing public buildings, and to make them more energy efficient. At the moment 30 municipalities (of the 98 municipalities in Denmark are involved in, or preparing, ESCO contracts. Nevertheless, ESCO-contracting still faces many challenges on the Danish market, as there is a widespread skepticism towards the concept amongst many stakeholders. The purpose of this paper is to discuss the various experience gained so far by municipalities use of ESCO-contracting, the different approached to ESCO-contracting being used in practice, as well as the different viewpoints drivers and barriers behind the development. The strong growth in ESCO-contracts reflects that the ESCO-concept fits well with a number of present problems that municipalities are facing, as well as a flexible adaptation to the local context in different municipalities.

  1. Variable gearing in a biologically inspired pneumatic actuator array

    A fundamental feature of pennate muscles is that muscle fibers are oriented at an angle to the line of action and rotate as they shorten, becoming more oblique throughout a contraction. This change in fiber orientation (pennation angle) can amplify the shortening velocity of a fiber and increase output velocity of the muscle. The velocity advantage resulting from dynamic changes in pennation angle can be characterized as a gear ratio (muscle velocity/fiber velocity). A recent study has shown that a pennate muscle's gear ratio varies automatically depending on the load such that a muscle operates with a high gear during rapid contractions and low gear during forceful contractions. We examined whether this variable gearing behavior can be replicated in a pennate array of artificial muscles. We used McKibben type pneumatic actuators, which shorten in tension when filled with compressed gas. Similar to muscle fibers, the actuators expand radially during shortening, a feature thought to be a critical part of the variable gearing mechanism in pennate muscles. We arranged McKibben actuators in an array oriented to mimic a pennate muscle, and quantified the system's gear ratio during contraction against a range of loads. Video was used to measure the gear ratio during each contraction. We find that similar to pennate muscles, the gear ratio decreases significantly with increasing load and that variable gearing results from load-dependent variation in the amount of actuator rotation. These results support the idea that variable gearing in pennate muscles is mediated by difference is fiber rotation and the direction of muscle bulging. The behavior of our artificial muscle array also highlights the potential benefits of bio-inspired architectures in artificial muscle arrays, including the ability to vary force and speed automatically in response to variable loading conditions.

    The purpose of this publication is to provide information on certain Canadian agricultural research contracts which are completed, published and available for loan. These contracts reports are documentation of research contracted out to non-federal government agencies, universities or individuals. Reports on contracts under the control of the Engineering and Statistical Research Institute are written by the contractor, and are reviewed by the scientific authority. Some reports date back to 1973, when the initial contracting program began. The first program was called DREAM (Development, Research, and Evaluation in Agricultural Mechanization). In 1977-78, projects under the Energy in Agriculture program were added. This was the beginning of the AERD (Agricultural Enginering Research and Development) program. In 1981, energy research had expanded and came under a separate progam called ERDAF (Energy Research and Development in Agriculture and Food). The remaining contract work stayed with the AERD program. This publication lists only contracts completed having final reports, and available contract reports with separate listings sorted by contract file number, title, author or subject.

    1992-01-01

    Natural gas is being viewed by many as the fuel of the 1990s and beyond because of its environmental qualities, relatively low cost and significant domestic resource base. However, in the Fall of 1991, a group of electric utility executives met with then Deputy Secretary of Energy Henson Moore and asserted that an inability to obtain long term gas contracts meant that supplies are unreliable and construction of gas-fueled generating stations is being discouraged. This study was requested by the Deputy Secretary to address the issues surrounding long-term gas contracts and supply reliability. The relationship between supply reliability and contracts is explained in terms of the number of buyers and sellers in a market. With the appropriate state regulatory policies, utilities can contract for gas and obtain reliable supplies at competitive market prices. Public utility commissioners are encouraged to permit utilities a free choice in signing gas contracts, but to allow only competitive market prices to be reflected in allowable fuel costs

  15. Standard form contracts and a smart contract future

    Directory of Open Access Journals (Sweden)

    Kristin B. Cornelius

    2018-05-01

    Full Text Available With a budding market of widespread smart contract implementation on the horizon, there is much conversation about how to regulate this new technology. Discourse on standard form contracts (SFCs and how they have been adopted in a digital environment is useful toward predicting how smart contracts might be interpreted. This essay provides a critical review of the discourse surrounding digitised SFCs and applies it to issues in smart contract regulation. An exploration of the literature surrounding specific instances SFCs finds that it lacks a close examination of the textual and documentary aspects of SFCs, which are particularly important in a digital environment as a shift in medium prompts a different procedural process. Instead, common perspectives are either based on outdated notions of paper versions of these contracts or on ideologies of industry and business that do not sufficiently address the needs of consumers/users in the digital age. Most importantly, noting the failure of contract law to address the inequities of SFCs in this environment can help prevent them from being codified further with smart contracts.

    Purpose The purpose of this study was to investigate the impact of varying knee flexion and quadriceps activity on patellofemoral indices measured on magnetic resonance imaging (MRI). Materials and Methods MRI of the knee was performed in 20 patients for indications other than patellar or patellofemoral pathology. Axial and sagittal sequences were performed in full extension of the knee with the quadriceps relaxed, full extension of the knee with the quadriceps contracted, 30° flexion of the knee with the quadriceps relaxed, and 30° flexion with the quadriceps contracted. Bisect offset, patella tilt angle, Insall-Salvati ratio and Caton-Deschamps index were measured. Results With the knee flexed to 30° and quadriceps relaxed, the mean values of patellar tilt angle, bisect offset, Insall-Salvati ratio and Caton-Deschamps index were all within normal limits. With the knee extended and quadriceps contracted, the mean patellar tilt angle (normal value, patellofemoral indices. MRI taken with the knee in 30° of flexion allows more reliable assessment of the patellofemoral joint and minimises the confounding effect of quadriceps contraction. PMID:27894177

This is a comprehensive and incisive analysis of the current law and of the relevant doctrines, including the equitable principles of rectification, as well as the powers of appeal courts or of the High Court when hearing an appeal from an arbitral award. The topic of interpretation of written contracts is fast-moving. It is of fundamental importance because this is the most significant commercial focus for dispute and because of the number of cross-border transactions to which English law is expressly applied by businesses.

  18. Drivers of Seasonal Variability in Marine Boundary Layer Aerosol Number Concentration Investigated Using a Steady State Approach

    Marine boundary layer (MBL) aerosol particles affect the climate through their interaction with MBL clouds. Although both MBL clouds and aerosol particles have pronounced seasonal cycles, the factors controlling seasonal variability of MBL aerosol particle concentration are not well constrained. In this paper an aerosol budget is constructed representing the effects of wet deposition, free-tropospheric entrainment, primary surface sources, and advection on the MBL accumulation mode aerosol number concentration (Na). These terms are then parameterized, and by assuming that on seasonal time scales Na is in steady state, the budget equation is rearranged to form a diagnostic equation for Na based on observable variables. Using data primarily collected in the subtropical northeast Pacific during the MAGIC campaign (Marine ARM (Atmospheric Radiation Measurement) GPCI (GCSS Pacific Cross-Section Intercomparison) Investigation of Clouds), estimates of both mean summer and winter Na concentrations are made using the simplified steady state model and seasonal mean observed variables. These are found to match well with the observed Na. To attribute the modeled difference between summer and winter aerosol concentrations to individual observed variables (e.g., precipitation rate and free-tropospheric aerosol number concentration), a local sensitivity analysis is combined with the seasonal difference in observed variables. This analysis shows that despite wintertime precipitation frequency being lower than summer, the higher winter precipitation rate accounted for approximately 60% of the modeled seasonal difference in Na, which emphasizes the importance of marine stratocumulus precipitation in determining MBL aerosol concentrations on longer time scales.

  19. Bilateral Coordination Strategy of Supply Chain with Bidirectional Option Contracts under Inflation

    2015-01-01

    Full Text Available As far as the price increase and the demand contraction caused by inflation are concerned, we establish a Stackelberg game model that incorporates bidirectional option contracts and the effect of inflation and derive the optimal ordering and production policies on a one-period two-stage supply chain composed of one supplier and one retailer. Through using the model of wholesale price contracts as the benchmark, we find that the introduction of bidirectional option contracts can benefit both the supplier and the retailer under inflation scenarios. Based on the conclusions drawn above, we design the bilateral coordination mechanism from the different perspective of two members involved and discuss how bidirectional option contracts should be set to achieve channel coordination under inflation scenarios. Through the sensitivity analysis, we illustrate the effect of inflation on the optimal decision variables and the optimal expected profits of the two parties with bidirectional option contracts.

    Since 2004, primary care in Germany has increasingly been provided in special general practitioner (GP)-centred health care contracts (HZV). To date there is limited evidence about the characteristics of their beneficiaries regarding morbidity burden and health care utilization. We analysed insurance claims data from all beneficiaries of the "Allgemeine Ortskrankenkasse (AOK) Baden-Württemberg" listed in 10 general practices that contracted in a special GP-centred health care contract (HZV). We compared beneficiaries enrolled in the HZV with those who were not enrolled in the contract. Comparisons included the number of hospital admissions in 2007-2008 and the Charlson comorbidity index. Insurance claims data of 6,026 beneficiaries were available for analysis. In the third quarter of 2009, 51% (3,066) of the beneficiaries were enrolled in the HZV. They were significantly older (mean 61 years [SD 18 years] vs. 49 years [SD 22 years]; p contract tended to be older and suffered from a higher morbidity burden when compared with beneficiaries of the same health care fund who were not enrolled in the contract. Besides, beneficiaries of the contract had higher numbers of hospital admissions during the two year period before enrolment. These findings have substantial implications for individualized care management approaches that may be offered to beneficiaries of GP-centred health care contracts.

  1. How variable is the number of triggered aftershocks?

    Marsan, D.; Helmstetter, A.

    2017-07-01

    Aftershock activity depends at first order on the main shock magnitude but also shows important fluctuations between shocks of equal magnitude. We here investigate these fluctuations, by quantifying them and by relating them to the main shock stress drop and other variables, for southern California earthquakes. A method is proposed in order to only count directly triggered aftershocks, rather than secondary aftershocks (i.e., triggered by previous aftershocks), and to only quantify fluctuations going beyond the natural Poisson variability. Testing of the method subjected to various model errors allows to quantify its robustness. It is found that these fluctuations follow a distribution that is well fitted by a lognormal distribution, with a coefficient of variation of about 1.0 to 1.1. A simple model is proposed to relate this observed dependence to main shock stress drop variability.

  2. Genesis of multipeaked waves of the esophagus: repetitive contractions or motion artifact?

    2010-06-01

    Multipeaked waves (MPW) in the distal esophagus occur frequently in patients with esophageal spastic motor disorders and diabetes mellitus and are thought to represent repetitive esophageal contractions. We aimed to investigate whether the relative motion between a stationary pressure sensor and contracted peristaltic esophageal segment that moves with respiration leads to the formation of MPW. We mathematically modeled the effect of relative movement between a moving pressure segment and a fixed pressure sensor on the pressure waveform morphology. We conducted retrospective analysis of 100 swallow-induced esophageal contractions in 10 patients, who demonstrated >30% MPW on high-resolution manometry (HRM) during standardized swallows. Finally, using HRM, we determined the effects of suspended breathing and hyperventilation on the waveform morphology in 10 patients prospectively. Modeling revealed that relative movement between a stationary pressure sensor and a moving contracted segment, contraction duration, contraction amplitude, respiratory frequency, and depth of respiration affects the waveform morphology. Retrospective analysis demonstrated a close temporal association with the onset of second and subsequent contractions in MPW with respiratory phase reversals. Numbers of peaks in MPW and respiratory phase reversals were closely related to the duration of contraction. In the prospective study, suspended breathing and hyperventilation resulted in a significant decrease and increase in the MPW frequency as well as the number of peaks within MPW respectively. We conclude that MPW observed during clinical motility studies are not indicative of repetitive esophageal contraction; rather they represent respiration-related movement of the contracted esophageal segment in relation to the stationary pressure sensor.

  4. Contracting for health services in New Zealand: a transaction cost analysis.

    Science.gov (United States)

    Ashton, T

    1998-02-01

    The splitting of the functions of purchaser and provider in the New Zealand health system in 1993 necessitated the use of explicit contracts between the two parties. This paper examines contracting experiences during the first two years of operation. The study focuses on four services: rest homes, primary care clinics, surgical services, and acute mental health services. The insights of transaction cost economics form the theoretical framework. The objective of this study was to examine whether the transaction costs associated with contracting vary across the four different services, and whether different types of contracts and contractual relationships are emerging as transactors attempt to reduce these costs. Information was collected in a series of 53 interviews with purchasers and providers, together with any relevant documentation. The results suggest that the costs of contracting are indeed greater for some services than for others. Other variables such as the style of negotiations, the type and specificity of contracts and the degree of monitoring also differ across the four services. At this early stage of the reform process, there was little evidence that purchasers and providers were attempting to reduce transaction costs by negotiating more flexible, longer-term, relational contracts. The main benefit from contracting to date has been improved accountability of service providers.

  5. Effect of fluid elasticity on the numerical stability of high-resolution schemes for high shearing contraction flows using OpenFOAM

    2017-01-01

    Full Text Available Viscoelastic fluids due to their non-linear nature play an important role in process and polymer industries. These non-linear characteristics of fluid, influence final outcome of the product. Such processes though look simple are numerically challenging to study, due to the loss of numerical stability. Over the years, various methodologies have been developed to overcome this numerical limitation. In spite of this, numerical solutions are considered distant from accuracy, as first-order upwind-differencing scheme (UDS is often employed for improving the stability of algorithm. To elude this effect, some works been reported in the past, where high-resolution-schemes (HRS were employed and Deborah number was varied. However, these works are limited to creeping flows and do not detail any information on the numerical stability of HRS. Hence, this article presents the numerical study of high shearing contraction flows, where stability of HRS are addressed in reference to fluid elasticity. Results suggest that all HRS show some order of undue oscillations in flow variable profiles, measured along vertical lines placed near contraction region in the upstream section of domain, at varied elasticity number E≈5. Furthermore, by E, a clear relationship between numerical stability of HRS and E was obtained, which states that the order of undue oscillations in flow variable profiles is directly proportional to E.

    Visual feedback can influence the force output by changing the power in frequencies below 1 Hz. However, it remains unknown whether visual guidance can help an individual reduce force variability voluntarily. The purpose of this study, therefore, was to determine whether an individual can voluntarily reduce force variability during constant contractions with visual guidance, and whether this reduction is associated with a decrease in the power of low-frequency oscillations (0-1 Hz) in force and muscle activity. Twenty young adults (27.6 ± 3.4 years) matched a force target of 15% MVC (maximal voluntary contraction) with ankle dorsiflexion. Participants performed six visually unrestricted contractions, from which we selected the trial with the least variability. Following, participants performed six visually guided contractions and were encouraged to reduce their force variability within two guidelines (±1 SD of the least variable unrestricted trial). Participants decreased the SD of force by 45% (P  0.2). The decrease in force variability was associated with decreased low-frequency oscillations (0-1 Hz) in force (R 2  = 0.59), which was associated with decreased low-frequency oscillations in EMG bursts (R 2  = 0.35). The reduction in low-frequency oscillations in EMG burst was positively associated with power in the interference EMG from 35 to 60 Hz (R 2  = 0.47). In conclusion, voluntary reduction of force variability is associated with decreased low-frequency oscillations in EMG bursts and consequently force output. We provide novel evidence that visual guidance allows healthy young adults to reduce force variability voluntarily likely by adjusting the low-frequency oscillations in the neural drive.

  7. The coordinating contracts of supply chain in a fuzzy decision environment.

    Sang, Shengju

    2016-01-01

    The rapid change of the product life cycle is making the parameters of the supply chain models more and more uncertain. Therefore, we consider the coordination mechanisms between one manufacturer and one retailer in a fuzzy decision marking environment, where the parameters of the models can be forecasted and expressed as the triangular fuzzy variables. The centralized decision-making system, two types of supply chain contracts, namely, the revenue sharing contract and the return contract are proposed. To obtain their optimal policies, the fuzzy set theory is adopted to solve these fuzzy models. Finally, three numerical examples are provided to analyze the impacts of the fuzziness of the market demand, retail price and salvage value of the product on the optimal solutions in two contracts. It shows that in order to obtain more fuzzy expected profits the retailer and the manufacturer should seek as low fuzziness of demand, high fuzziness of the retail price and the salvage value as possible in both contracts.

    Full Text Available The purpose of this study is to investigate the impact to psychological contract on the organisational commitment of public sector employees in Maldives. The research draws a sample of 100 respondents from ministry of Youth and Sports, Maldives, using simple random probability sampling technique. A Likert-Scale with 1-5 rating was used to obtain. The Questionnaire distributed included five variables to measure the Psychological Contract construct. These are ‘trust, ‘mutual obligation’, ‘perceived fairness, and ‘length of contract’. The dependent variable was organizational commitment (affective commitment, which is measured using ‘sense of belonging to the organization’, pride in organization membership’, and meaning associated with the work’. The data collected was processed using the Statistical Package for Social Science (SPSS version 22.0 for windows. The correlation analysis shows that the dimensions of psychological contract have positive correlation with affective commitment. The main results indicate that psychological contract dimension such as fulfillment of mutual obligations, perceived fairness and length of contract has a positive and significant impact on affective commitment. However this study found that psychological contract dimension, trust in employer has a positive correlation although it does not have a significant impact on affective commitment. Implications and suggestion for future researches are discussed.

    The variable flavor number scheme may be used to describe parton distributions in the transition region in which one heavy quark gradually becomes a light flavor. We present first three-loop results to the massive operator matrix elements A{sub gg} and A{sub gq} for the contributions due to bubble topologies {proportional_to}T{sub F}{sup 2} n{sub f} at general values of the Mellin variable N. The calculation has been performed using higher transcendental functions and by applying modern summation technologies encoded in the package Sigma. These massive operator matrix elements describe the universal contributions in the matching of different flavor sectors, which are the logarithmic and constant contributions in the ratio of m{sup 2}{sub H}/Q{sup 2}, with Q{sup 2} the virtuality and m{sub H} the respective heavy quark mass. The framework allows to derive heavy quark parton distributions which are of relevance for calculating specific processes at hadron-hadron colliders.

    Analysis of publication activity in the field of biomedicine shows insignificant input of Russia in the world scientific product. This is largely due to the lack of incentives for researchers. Article describes stimulation of researchers in Russia, compares it with foreign models, formulates main shortcomings of support and stimulation of research in Russia and introduces the concept of effective contract. Development of personnel motivation and stimulation of employees of scientific and research organizations in the field of health. As a successful experience the article describes the implementation of effective contract in Veltishev Research and Clinical Institute for Pediatrics where for years remuneration of researchers depended upon their positions without consideration of research results. Effective contract brought significant changes in the traditional system setting new performance and efficiency criteria. New evaluation system took into account publication activity, presentation activity, implementation of research results, raising scientific personnel, thesis work and income-generating activities. Introduction of effective contract already in the second year led to a rise in the number of foreign publications, publications in journals with impact factor of more than 2, the general increase in the number of articles in peer-reviewed journals with impact factor more than 0.3, the growth of the number of articles by 1 researcher, Hirsch index improving both by individual employees and the entire Institute, increase of grant activity and presentation activity at top-rated professional congresses. The growth of publication and presentation activities has been achieved at the reduction of research staff by 23%. From financial viewpoint effective contract resulted in the redistribution of resources in favour of more efficient researchers. The introduction of effective contract and increase of requirements for scientific output did not cause resistance of staff

    TraceContract is an API (Application Programming Interface) for trace analysis. A trace is a sequence of events, and can, for example, be generated by a running program, instrumented appropriately to generate events. An event can be any data object. An example of a trace is a log file containing events that a programmer has found important to record during a program execution. Trace - Contract takes as input such a trace together with a specification formulated using the API and reports on any violations of the specification, potentially calling code (reactions) to be executed when violations are detected. The software is developed as an internal DSL (Domain Specific Language) in the Scala programming language. Scala is a relatively new programming language that is specifically convenient for defining such internal DSLs due to a number of language characteristics. This includes Scala s elegant combination of object-oriented and functional programming, a succinct notation, and an advanced type system. The DSL offers a combination of data-parameterized state machines and temporal logic, which is novel. As an extension of Scala, it is a very expressive and convenient log file analysis framework.

    Introduction Whereas deficits in muscle function, particularly power production, develop in old age and are risk factors for mobility impairment, a complete understanding of muscle fatigue during dynamic contractions is lacking. We tested hypotheses related to torque-producing capacity, fatigue resistance, and variability of torque production during repeated maximal contractions in healthy older, mobility-impaired older, and young women. Methods Knee extensor fatigue (decline in torque) was measured during 4 min of dynamic contractions. Torque variability was characterized using a novel 4-component logistic regression model. Results Young women produced more torque at baseline and during the protocol than older women (P torque variability differed by group (P = 0.022) and was greater in older impaired compared with young women (P = 0.010). Conclusions These results suggest that increased torque variability may combine with baseline muscle weakness to limit function, particularly in older adults with mobility impairments. PMID:23674266

    To date, a few works have performed a correlation of metabolic variables in bacteria; however specific correlations with these variables have not been reported. In this work, we included 36 human pathogenic bacteria and 18 non- or less-pathogenic-related bacteria and obtained all metabolic variables, including enzymes, metabolic pathways, enzymatic steps and specific metabolic pathways, and enzymatic steps of particular metabolic processes, from a reliable metabolic database (KEGG). Then, we correlated the number of the open reading frames (ORF) with these variables and with the proportions of these variables, and we observed a negative correlation with the proportion of enzymes (r = -0.506, p < 0.0001), metabolic pathways (r = -0.871, p < 00.0001), enzymatic reactions (r = -0.749, p < 00.0001), and with the proportions of central metabolism variables as well as a positive correlation with the proportions of multistep reactions (r = 0.650, p < 00.0001) and secondary metabolism variables. The proportion of multifunctional reactions (r: -0.114, p = 0.41) and the proportion of enzymatic steps (r: -0.205, p = 0.14) did not present a significant correlation. These correlations indicate that as the size of a genome (measured in the number of ORFs) increases, the proportion of genes that encode enzymes significantly diminishes (especially those related to central metabolism), suggesting that when essential metabolic pathways are complete, an increase in the number of ORFs does not require a similar increase in the metabolic pathways and enzymes, but only a slight increase is sufficient to cope with a large genome.

  15. Supply Chain Contracts with Multiple Retailers in a Fuzzy Demand Environment

    2013-01-01

    Full Text Available This study investigates supply chain contracts with a supplier and multiple competing retailers in a fuzzy demand environment. The market demand is considered as a positive triangular fuzzy number. The models of centralized decision, return contract, and revenue-sharing contract are built by the method of fuzzy cut sets theory, and their optimal policies are also proposed. Finally, an example is given to illustrate and validate the models and conclusions. It is shown that the optimal total order quantity of the retailers fluctuates at the center of the fuzzy demand. With the rise of the number of retailers, the optimal order quantity and the fuzzy expected profit for each retailer will decrease, and the fuzzy expected profit for supplier will increase.

  16. Procurement of construction services: a case study on bidding competition in Singapore public sector contracts

    There are many variables that public clients need to consider in their bidding procedure to enhance efficiency in their procurement for construction services. This paper focusses on the competitive bidding process for public sector procurement of construction services in Singapore. A distinctive feature of the Singapore government competitive bidding process is that full bidding feedback information is released to all competing bidders (and public). The specific objectives are: (i) to examine the degree of competition in the construction markets; and (ii) to examine the bidding performance of competing bidders. Based on a collection of bidding data for a 15-month period, the results show the market environment of the Singapore public sector construction contracting is highly competitive with long bidder lists. In selection of contractors, only 50% of the contracts were awarded to lowest bidders. The results also show that the competing contractors can be broadly classified into three groups based on their bidding performance in terms of number of bidding attempts, bidding success rate and bidding competitiveness. These results provide a useful insight into the bidding competition in the Singapore public sector construction contracting, especially to new market entrants and foreign contractors who want to bid for jobs in Singapore.

    does not mean that the guarantor gives up his right to claim from the debtor the amount paid because otherwise such transaction would represent an indirect gift rather than surety. This does mean that there is no remuneration for surety - a benefit the guarantor could expect from entering into a surety contract. Therefore, the author rejects the approach followed by a number of Serbia's courts that bankruptcy trustee may request a declaration that, in accordance with the rules on avoiding debtor's transactions, a surety contract has no legal effects.

    Brucellosis-induced abortion can result in significant economic loss to farm animals. Brucellosis can be transmitted to humans during slaughter of infected animals or via consumption of contaminated food products. Strain identification of Brucella isolates can reveal the route of transmission. Brucella strains were isolated from vaginal swabs of farm animal, cow milk and from human blood cultures. Multiplex PCR was used to identify Brucella species, and owing to high DNA homology among Brucella isolates, multiple-locus variable-number tandem repeat analysis (MLVA) based on the number of tandem repeats at 16 different genomic loci was used for strain identification. Multiplex PCR categorized the isolates into B. abortus (n = 7), B. melitensis (n = 37), B. suis (n = 3), and 5 of unknown Brucella spp. MLVA-16 clustering analysis differentiated the strains into various genotypes, with Brucella isolates from the same geographic region being closely related, and revealed that the Thai isolates were phylogenetically distinct from those in other countries, including within the Southeast Asian region. Thus, MLVA-16 typing has utility in epidemiological studies.

  19. Polymorphic Contracts

    Belo, João Filipe; Greenberg, Michael; Igarashi, Atsushi; Pierce, Benjamin C.

    Manifest contracts track precise properties by refining types with predicates - e.g., {x : Int |x > 0 } denotes the positive integers. Contracts and polymorphism make a natural combination: programmers can give strong contracts to abstract types, precisely stating pre- and post-conditions while hiding implementation details - for example, an abstract type of stacks might specify that the pop operation has input type {x :α Stack |not ( empty x )} . We formalize this combination by defining FH, a polymorphic calculus with manifest contracts, and establishing fundamental properties including type soundness and relational parametricity. Our development relies on a significant technical improvement over earlier presentations of contracts: instead of introducing a denotational model to break a problematic circularity between typing, subtyping, and evaluation, we develop the metatheory of contracts in a completely syntactic fashion, omitting subtyping from the core system and recovering it post facto as a derived property.

    PCR analysis of 198 Bacillus anthracis isolates revealed a variable region of DNA sequence differing in length among the isolates. Five Polymorphisms differed by the presence Of two to six copies of the 12-bp tandem repeat 5{prime}-CAATATCAACAA-3{prime}. This variable-number tandem repeat (VNTR) region is located within a larger sequence containing one complete open reading frame that encodes a putative 30-kDa protein. Length variation did not change the reading frame of the encoded protein and only changed the copy number of a 4-amino-acid sequence (QYQQ) from 2 to 6. The structure of the VNTR region suggests that these multiple repeats are generated by recombination or polymerase slippage. Protein structures predicted from the reverse-translated DNA sequence suggest that any structural changes in the encoded protein are confined to the region encoded by the VNTR sequence. Copy number differences in the VNTR region were used to define five different B. anthracis alleles. Characterization of 198 isolates revealed allele frequencies of 6.1, 17.7, 59.6, 5.6, and 11.1% sequentially from shorter to longer alleles. The high degree of polymorphism in the VNTR region provides a criterion for assigning isolates to five allelic categories. There is a correlation between categories and geographic distribution. Such molecular markers can be used to monitor the epidemiology of anthrax outbreaks in domestic and native herbivore populations. 22 refs., 4 figs., 3 tabs.

    Coal contracts for the new Asian Independent Power Producers (IPPs) are examined. Since most IPPs will be selling to state electricity utilities, often in competition with power plant using other fuels, coal based IPPs must negotiate advantageous coal supply contracts several years before the commissioning of a plant, and must ensure security of supply for at least the life of the construction loan. A more recent trend in the developed world is the Merchant IPP, where there is no guaranteed electricity sale. Lenders are wary of IPPs relying an imported coal, and insist on binding fuel contracts, while coal companies are wary of the quantity of information demanded by these lenders. A full understanding of the risks involved is needed; and a method of price indexation for the contracts. Contracts must also specify security of supply, coal quality, freight contracts and other details. 2 figs.

If we start from the definition of administrative contracts as it appears in Law no. 554/2004, these include contracts by public authorities which concern the enhancement of public property execution of works of public interest, public services, public procurement and other administrative contracts provided by special laws and subject to the jurisdiction of the administrative courts.

  4. Nova Scotia electricity market : frameworks for renewable energy contracting and cogeneration contracting : discussion document

    International Nuclear Information System (INIS)

    2006-01-01

    The recent Electricity Marketplace Governance Committee of Nova Scotia report issued a number of recommendations regarding renewable and cogeneration sales to retail consumers, as well as recommendations for top-up, spill rates and back-up rates to complement the operation of independent generating facilities. This discussion paper examined issues which need to be addressed in order to implement the recommendations. The discussion paper also included recommendations relating to the purchase of cogeneration output by the Nova Scotia Power Inc. (NSPI) under long term power purchase agreements. The aim of the paper was to provide a basis for the further discussion of issues in preparation for the development of future rules and regulations. The first part of the document identified ways for buyers and sellers to arrange contracts, as well as issues that need to be addressed at the institutional level to enable arrangements. Options for financial contracts and physical contracts were reviewed.The second part of the document examined pricing issues in the context of both financial and physical contract arrangements. Resolutions for both sets of options were proposed. Energy pricing principles were reviewed, as well as various pricing options and issues related to the analysis of price requirements. It was concluded that in order to support the safe, reliable and economic supply of electricity, the design of the electricity market should enable maximum flexibility in contractual arrangements and facilitate competition in ways that do not harm other parties

    Portfolio optimization is a technique widely used to select investments in economic and financial zones. In the Brazilian Electric Market the portfolio models must consider not only different types of contracts used in the free market, but also different types of markets: the free market, the captive market and the spot market. Normally, the question is knowing which proportion of energy should be sold in each market, in order to maximize the return and minimize the risk. This article deals with a problem from the point of view of a power generator, where their objective is to maximize its profit, to serve their obligations regarding the delivery of energy and minimizing the risk associated with the occurrence of Spot Price - minimum (Spot Price). It is considered that the generator has flexible contracts and inflexible contracts to sell the energy. Inflexible contracts have delivery obligations of fixed energy and flexible contracts allow, the holder of the flexibility, to deliver or to receive an amount of variable energy. In this case, the holder of flexibility may be the purchaser or the generator. (author)

    Energy service contracting can provide a cost-effective route to overcoming barriers to energy efficiency. Energy service contracts allow the client to reduce operating costs, transfer risk and concentrate attention on core activities. However, the energy services model may only be appropriate for a subset of energy services and energy using organisations. A challenge for both business strategy and public policy is to identify those situations in which energy service contracting is most likely to be appropriate and the conditions under which it is most likely to succeed. Energy service contracting is a form of outsourcing. It will only be chosen where the expected reduction in the production cost of supplying energy services can more than offset the transaction cost of negotiating and managing the relationship with the energy service provider. Production costs will be determined by a combination of the physical characteristics of the energy system and the technical efficiency of the relevant organisational arrangements, including economies of scale and specialisation. Transaction costs, in turn, will be determined by the complexity of the energy service, the 'specificity' of the investments made by the contractor, the competitiveness of the energy services market and the relevant legal, financial and regulatory rules. This paper develops these ideas into a general framework that may be used to assess the feasibility of energy service contracting in different circumstances. The framework leads to a number of hypotheses that are suitable for empirical test. (author)

  16. Investigating the Variability in Cumulus Cloud Number as a Function of Subdomain Size and Organization using large-domain LES

    Science.gov (United States)

    Neggers, R.

    2017-12-01

    Recent advances in supercomputing have introduced a "grey zone" in the representation of cumulus convection in general circulation models, in which this process is partially resolved. Cumulus parameterizations need to be made scale-aware and scale-adaptive to be able to conceptually and practically deal with this situation. A potential way forward are schemes formulated in terms of discretized Cloud Size Densities, or CSDs. Advantages include i) the introduction of scale-awareness at the foundation of the scheme, and ii) the possibility to apply size-filtering of parameterized convective transport and clouds. The CSD is a new variable that requires closure; this concerns its shape, its range, but also variability in cloud number that can appear due to i) subsampling effects and ii) organization in a cloud field. The goal of this study is to gain insight by means of sub-domain analyses of various large-domain LES realizations of cumulus cloud populations. For a series of three-dimensional snapshots, each with a different degree of organization, the cloud size distribution is calculated in all subdomains, for a range of subdomain sizes. The standard deviation of the number of clouds of a certain size is found to decrease with the subdomain size, following a powerlaw scaling corresponding to an inverse-linear dependence. Cloud number variability also increases with cloud size; this reflects that subsampling affects the largest clouds first, due to their typically larger neighbor spacing. Rewriting this dependence in terms of two dimensionless groups, by dividing by cloud number and cloud size respectively, yields a data collapse. Organization in the cloud field is found to act on top of this primary dependence, by enhancing the cloud number variability at the smaller sizes. This behavior reflects that small clouds start to "live" on top of larger structures such as cold pools, favoring or inhibiting their formation (as illustrated by the attached figure of cloud mask

    The authors used radioligand binding and studies of cell contraction to characterize muscarinic receptors on dispersed smooth muscle cells from rabbit proximal and distal colon. Cells obtained after serial incubations in collagenase were used to measure binding of tritiated quinuclidinyl benzilate ([ 3 H]QNB). At 37 degree C, specific [ 3 H]QNB binding was saturable and linearly related to cell number. Nonlinear regression analysis was used to determine the affinity of [ 3 H]QNB for its receptor. The IC 50 for the muscarinic agonists bethanechol and oxotremorine were 80 and 0.57 μM, respectively. Hill coefficients were 0.67 for both, suggesting more complex interaction involving receptors of different affinities. In studies of cell contraction, bethanechol stimulated a dose-dependent decrease in cell length with half the maximal contraction occurring at 100 pM. These results suggest that (1) contraction is mediated by binding of bethanechol to M 2 -muscarinic receptors and that (2) there are a large number of spare receptors in colonic smooth muscle

    The purpose of this study was to record the discharge characteristics of tibialis anterior motor units over a range of target forces and to import these data, along with previously reported observations, into a computational model to compare experimental and simulated measures of torque variability during isometric contractions with the dorsiflexor muscles. The discharge characteristics of 44 motor units were quantified during brief isometric contractions at torques that ranged from recruitment threshold to an average of 22 ± 14.4% maximal voluntary contraction (MVC) torque above recruitment threshold. The minimal [range: 5.8-19.8 pulses per second (pps)] and peak (range: 8.6-37.5 pps) discharge rates of motor units were positively related to the recruitment threshold torque (R(2) ≥ 0.266; P recruitment was positively associated with recruitment threshold torque (R(2) = 0.443; P recruitment threshold torque. The variability in the simulated torque did not differ from the experimental values once the recruitment range was set to ∼85% MVC torque, and the association between motor twitch contraction times and peak twitch torque was defined as a weak linear association (R(2) = 0.096; P motor units in the tibialis anterior.

  20. Reviving Ulysses contracts.

    Spellecy, Ryan

    2003-12-01

    Ulysses contracts have faced paternalism objections since they first were proposed. Since the contracts are designed to override a present request from a legally competent patient in favor of a past request made by that patient, enforcement of these contracts was argued to be unjustifiable strong paternalism. Recent legal developments and new theories of practical reasoning suggest that the discussion of Ulysses contracts should be revived. This paper argues that with a proper understanding of the future-directed planning embodied in Ulysses contracts, the charge of strong paternalism can be answered, and the enforcement of some Ulysses contracts may be justified under the rubric of weak paternalism.

  7. The resurgence of selective contracting restrictions.

    Marsteller, J A; Bovbjerg, R R; Nichols, L M; Verrilli, D K

    1997-10-01

    As managed care has spread, so has legislation to force plans to contract with any willing provider (AWP) and give patients freedom of choice (FOC). Managed care organizations' selective networks and provider integration reduce patient access to providers, along with provider access to paying patients, so many providers have lobbied for AWP-FOC laws. In opposition are managed care organizations (MCOs), which want full freedom to contract selectively to control prices and utilization. This article comprehensively describes laws in all fifty-one jurisdictions, classifies their relative strength, and assesses the implications of the laws. Most are relatively weak forms and all are limited in application by ERISA and the federal HMO Act. The article also uses an associative multivariate analysis to relate the selective contracting environments to HMO penetration rates, rural population, physician density, and other variables. States with weak laws also have higher HMO penetration and higher physician density, but smaller rural populations. We conclude that the strongest laws overly restrict the management of care, to the likely detriment of cost control. But where market power is rapidly concentrating, not restricting selective contracting could diminish long-term competition and patient access to care. In the face of uncertainty about the impact of these laws, an intermediate approach may be better than all or nothing. States should consider mandating that plans offer point-of-service options, for a separate premium. This option expands patient choice of plans at the time of enrollment and of providers at the time of care, yet maintains plans' ability to control core providers.

  8. Variability of sub-micrometer particle number size distributions and concentrations in the Western Mediterranean regional background

    Directory of Open Access Journals (Sweden)

    Michael Cusack

    2013-02-01

    Full Text Available This study focuses on the daily and seasonal variability of particle number size distributions and concentrations, performed at the Montseny (MSY regional background station in the western Mediterranean from October 2010 to June 2011. Particle number concentrations at MSY were shown to be within range of various other sites across Europe reported in literature, but the seasonality of the particle number size distributions revealed significant differences. The Aitken mode is the dominant particle mode at MSY, with arithmetic mean concentrations of 1698 cm3, followed by the accumulation mode (877 cm−3 and the nucleation mode (246 cm−3. Concentrations showed a strong seasonal variability with large increases in particle number concentrations observed from the colder to warmer months. The modality of median size distributions was typically bimodal, except under polluted conditions when the size distribution was unimodal. During the colder months, the daily variation of particle number size distributions are strongly influenced by a diurnal breeze system, whereby the Aitken and accumulation modes vary similarly to PM1 and BC mass concentrations, with nocturnal minima and sharp day-time increases owing to the development of a diurnal mountain breeze. Under clean air conditions, high levels of nucleation and lower Aitken mode concentrations were measured, highlighting the importance of new particle formation as a source of particles in the absence of a significant condensation sink. During the warmer months, nucleation mode concentrations were observed to be relatively elevated both under polluted and clean conditions due to increased photochemical reactions, with enhanced subsequent growth owing to elevated concentrations of condensable organic vapours produced from biogenic volatile organic compounds, indicating that nucleation at MSY does not exclusively occur under clean air conditions. Finally, mixing of air masses between polluted and non

    The biophysical relationships between physiological sensors and actuators were fundamental to the development of early life forms, as responding to external stimuli promptly is key to survival. We study an unusual protist Spirostomum ambiguum, a single-celled organism that can grow up to 4mm in size, visible to the naked eye, as a model system for impulsive systems. Coiling its cytoskeleton, this ciliate can contract its long body within milliseconds, one of the fastest accelerations known in cell biology. We demonstrate that these rapid contractions generate long-ranged vortex flows that can trigger other cells to contract, repeatedly, which collectively leads to an ultra-fast hydrodynamic signal transduction across a colony that moves hundreds of times faster than the swimming speed. By combining high-speed PIV experiments and analytical modelling we determine the critical rheosensitivity required to sustain these signal waves. Whereas the biological motive is not fully understood, contractions are known to release toxins from membrane-bound extrusomes, thus we hypothesize that synchronised discharges could facilitate the repulsion of large-scale predators cooperatively. Please also see our other talk ``Rheosensing by impulsive cells at intermediate Reynolds numbers''.

  10. Venture financing of start-ups: A model of contract between VC fund and entrepreneur

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Venture capital has become one of the main sources of innovation in the modern, global economy. It is not just a substitute for bank loans: it has proven to be a more efficient way of financing projects at different stages. On one hand, venture financing allows for projects with higher risk, which leads to the possibility of higher returns on investment. On the other hand, venture investors who usually have managerial experience often participate in governing the business, which certainly adds value to the enterprise. In this paper we establish the model of contract between the venture capital fund and the entrepreneur, focusing on probably the most important issue of this contract: the shares of the parties in the business. The shares in the company determine the distribution of the joint surplus. The expected joint profits are not just exogenously specified in the contract but are dependent on the behavioral variables of both parties at the stage of fulfilling the contract. We call the behavioral variable of the entrepreneur ‘effort’ and the one of the venture fund ‘advice’. The probability of the project’s success, and hence the expected joint revenues, are increased by these two. However, both kinds of effort are costly to the respective parties that have made them. Based on this fact we can elaborate the profit functions of both sides of the contract. Our model can be considered as a basis for specifying contracts concerning venture financing. It can provide the logic for how the equilibrium shares of entrepreneur and venture fund are obtained.

    We present predictions for the prompt-neutrino flux arising from the decay of charmed mesons and baryons produced by the interactions of high-energy cosmic rays in the Earth's atmosphere, making use of a QCD approach on the basis of the general-mass variable-flavor-number scheme for the description of charm hadroproduction at NLO, complemented by a consistent set of fragmentation functions. We compare the theoretical results to those already obtained by our and other groups with different theoretical approaches. We provide comparisons with the experimental results obtained by the IceCube Collaboration in two different analyses and we discuss the implications for parton distribution functions.

    2015-01-01

    Full Text Available Administrative contracts are a special type of contract where usually one of the contracting parties is a public law body and which is concluded for the performance of public service and the realization of a public interest. They go a long way since its inception to its eventual final acceptance of all the legal systems. One of the enduring characteristics of this type of contract is their disquised or unnoticed existence. This is why only monitoring their development may lead to a complete understanding of the importance and essence of this institution as well as the need for its complete legal regulation.

    Yuan, Zhiqiang; Liu, Dong; Jiang, Chuanwen

    2007-01-01

    In this paper, the supply function model is employed to simulate the bidding strategy of suppliers in the power pool, and models of the supply function with future contracts are presented. It is proved that only one of the parameters between slope and intercept of the bidding curve is an independent variable in order to achieve definite equilibrium. In the meantime, the equilibria of the bidding strategy about suppliers are studied when different intercepts of the bidding curve are chosen. Some examples are employed to study the Nash equilibrium strategies of suppliers with different future contracts in various bidding strategy models. The results show that the equilibria are different in different bidding strategy models, but the future contracts can effectively make spot prices decrease in all the models

  18. Positive and negative implications entailed by fixed-term employment contracts

    Directory of Open Access Journals (Sweden)

    Mihaela-Emilia Marica

    2018-03-01

    Full Text Available Generally, fixed-term employment contracts are seen as a stepping stone to permanent employment; they have become popular among the flexible forms of work contracts, and are the object of an increasing number of debates and assessments, investigating both the respective legislation and the specific consequences on the parties concluding a fixed-term employment contract. Despite the positive aspects of temporary employment – a positive effect on the rate of employment, and the common perception of such contracts as a preliminary step to permanent employment, as well as the flexibility they bring to the labor market – one cannot ignore the negative implications of fixed-term contracts on the nature of the employment relationship, the system of social protection, the working conditions, the economic security, and the job stability. Based on these considerations, the present paper investigates the advantages and disadvantages of the individual fixed-term employment contract from the standpoints of both employers and employees. Obviously, this approach aims to explore the usefulness and importance of these contract types, as means for balancing the needs of employers and employees on the labor market, and for identifying concrete instances that justify the liberalization of fixed-term employment, despite all the inherent risks entailed by any type of non-standard work: lack of job security; reduced social protection and security for those concluding such a contract.

  19. Governance in Blockchain Technologies & Social Contract Theories

    Directory of Open Access Journals (Sweden)

    Wessel Reijers

    2016-12-01

    Full Text Available This paper is placed in the context of a growing number of social and political critiques of blockchain technologies. We focus on the supposed potential of blockchain technologies to transform political institutions that are central to contemporary human societies, such as money, property rights regimes, and systems of democratic governance. Our aim is to examine the way blockchain technologies canbring about - and justify - new models of governance. To do so, we draw on the philosophical works of Hobbes, Rousseau, and Rawls, analyzing blockchain governance in terms of contrasting social contract theories. We begin by comparing the justifications of blockchain governance offered by members of the blockchain developers’ community with the justifications of governance presented within social contract theories. We then examine the extent to which the model of governance offered by blockchain technologies reflects key governance themes and assumptions located within social contract theories, focusing on the notions of sovereignty, the initial situation, decentralization and distributive justice.

  1. Grounds for dispensing with public tender procedures in Government Contracting

    Directory of Open Access Journals (Sweden)

    P Bolton

    2006-01-01

    Full Text Available The Constitution of the Republic of South Africa1 provides that organs of state must comply with five principles when procuring goods or services: procurement procedures must be fair, equitable, transparent, competitive and cost-effective. In short, this means that organs of state should make use of competition when procuring goods or services. They should shop around and attract the maximum number of contractors who will participate in such competition. The aim should be the attainment of value for money, meaning, public money should be spent in an effective and efficient manner. Those who participate in competitions should also be treated fairly and without bias. In principle, no preferences should be afforded to different contractors; all contracting parties should have equal access to competition; some contractors should not be afforded more time for the preparation and submission of quotes or tenders than others; and the same information should be made available to all contracting parties. Government procurement procedures should further be transparent, meaning public or open. Thus, organs of state should not contract behind closed doors – government contracts should, as a rule, be advertised. Depending on the nature and value of a particular contract, the use of a public call for tenders is generally the best way to ensure compliance with the principles in the Constitution. By nature, a pubic call for tenders is open, it assists in the prevention of fraud and favouritism, and it ensures that the maximum number of contractors is approached to compete for a contract.Organs of state can also compare prices and quality and can contract with whoever offers the best deal. Most legislation therefore proceeds on the basis that procurement takes place by way of tendering. Generally, contracts above R200 000 are subject to public tender procedures. In certain instances, however, a public call for tenders may be inappropriate regardless of the high

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

    Directory of Open Access Journals (Sweden)

    Alexandru MATEESCU

    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.

    Recent population-based studies identified the magnitude of interleukin 6 (IL6) serum levels as a marker for functional disability, and a predictor of disability and mortality among the elderly. We investigated whether there was evidence in Southern Italy of an association between the IL6 gene variable number of tandem repeats (VNTR) polymorphism and extreme longevity, and tested for the possible interaction of apolipoprotein E (APOE) alleles with the IL6 VNTR alleles. Four alleles coding for variants of four different lengths have been identified: allele A [760 base pairs (bp)], allele B (680 bp), allele C (640 bp), and allele D (610 bp). IL6 VNTR and APOE allele and genotype frequencies were studied in a total of 61 centenarians and 94 middle-aged subjects from Southern Italy. The IL6 VNTR allele B was overrepresented in the younger control group compared with centenarians (odds ratio: 0.56, 95% confidence interval: 0.35-0.88, Bonferroni p-value VNTR alleles and APOE alleles on the odds ratios to reach extreme longevity were evaluated for the smallest number of subjects in centenarians and younger controls. Our findings suggested that the presence of the IL6 VNTR allele B could be detrimental for reaching extreme longevity.

    2015-05-01

    To improve the methodology of HIV cluster analysis, we addressed how analysis of HIV clustering is associated with parameters that can affect the outcome of viral clustering. The extent of HIV clustering and tree certainty was compared between 401 HIV-1C near full-length genome sequences and subgenomic regions retrieved from the LANL HIV Database. Sliding window analysis was based on 99 windows of 1,000 bp and 45 windows of 2,000 bp. Potential associations between the extent of HIV clustering and sequence length and the number of variable and informative sites were evaluated. The near full-length genome HIV sequences showed the highest extent of HIV clustering and the highest tree certainty. At the bootstrap threshold of 0.80 in maximum likelihood (ML) analysis, 58.9% of near full-length HIV-1C sequences but only 15.5% of partial pol sequences (ViroSeq) were found in clusters. Among HIV-1 structural genes, pol showed the highest extent of clustering (38.9% at a bootstrap threshold of 0.80), although it was significantly lower than in the near full-length genome sequences. The extent of HIV clustering was significantly higher for sliding windows of 2,000 bp than 1,000 bp. We found a strong association between the sequence length and proportion of HIV sequences in clusters, and a moderate association between the number of variable and informative sites and the proportion of HIV sequences in clusters. In HIV cluster analysis, the extent of detectable HIV clustering is directly associated with the length of viral sequences used, as well as the number of variable and informative sites. Near full-length genome sequences could provide the most informative HIV cluster analysis. Selected subgenomic regions with a high extent of HIV clustering and high tree certainty could also be considered as a second choice.

    2015-03-01

    Full Text Available Aim: Skin grafting is a common clinical practice for plastic surgeons, yet primary contraction of these grafts is a neglected topic. This study was designed to investigate primary contraction and introduce the shape of skin graft as a possible factor that modifies primary contraction behavior, using porcine models. Methods: In the first series, full-thickness skin grafts (FTSGs and split-thickness skin grafts (STSGs were compared. In a second series, how the shape of the skin graft affected the degree of contraction was examined. Results: The mean percentage of FTSG shrinkage was 12.04%, and the median was 12.18%. The mean percentage of STSG shrinkage was 6.87%, and the median was 5%. Circle-shaped and square-shaped FTSGs showed mean/median graft shrinkage of 5.83%/6.93% and 4.15%/3.75%, respectively. In STSGs, the circle-shaped and square-shaped grafts had mean/median graft shrinkage of 1.07%/0% and 0.31%/0%, respectively. Conclusion: Our preliminary report revealed an expected greater shrinkage of FTSGs compared with STSGs. Furthermore, in a limited number of specimens, the shape of the skin graft seemed to affect the primary contraction of the STSGs.

  10. Development and validation of a single-tube multiple-locus variable number tandem repeat analysis for Klebsiella pneumoniae.

    Antoinette A T P Brink

    Full Text Available Genotyping of Klebsiella pneumoniae is indispensable for management of nosocomial infections, monitoring of emerging strains--including extended-spectrum beta-lactamase (ESBL producers-, and general epidemiology. Such objectives require a high-resolution genotyping method with a fixed scheme that allows (1 long-term retrospective and prospective assessment, (2 objective result readout and (3 library storage for database development and exchangeable results. We have developed a multiple-locus variable number tandem repeat analysis (MLVA using a single-tube fluorescently primed multiplex PCR for 8 Variable Number Tandem Repeats (VNTRs and automated fragment size analysis. The type allocation scheme was optimized using 224 K. pneumoniae clinical isolates, which yielded 101 MLVA types. The method was compared to the gold standard multilocus sequence typing (MLST using a subset of these clinical isolates (n = 95 and found to be highly concordant, with at least as high a resolution but with considerably less hands-on time. Our results position this MLVA scheme as an appropriate, high-throughput and relatively low-cost tool for K. pneumoniae epidemiology.

    Full Text Available Abstract Background Current devices for measuring muscle contraction in vivo have limited accuracy in establishing and re-establishing the optimum muscle length. They are variable in the reproducibility to determine the muscle contraction at this length, and often do not maintain precise conditions during the examination. Consequently, for clinical testing only semi-quantitative methods have been used. Methods We present a newly developed myograph, an accurate measuring device for muscle contraction, consisting of three elements. Firstly, an element for adjusting the axle of the device and the physiological axis of muscle contraction; secondly, an element to accurately position and reposition the extremity of the muscle; and thirdly, an element for the progressive pre-stretching and isometric locking of the target muscle. Thus it is possible to examine individual in vivo muscles in every pre-stretched, specified position, to maintain constant muscle-length conditions, and to accurately re-establish the conditions of the measurement process at later sessions. Results In a sequence of experiments the force of contraction of the muscle at differing stretching lengths were recorded and the forces determined. The optimum muscle length for maximal force of contraction was established. In a following sequence of experiments with smaller graduations around this optimal stretching length an increasingly accurate optimum muscle length for maximal force of contraction was determined. This optimum length was also accurately re-established at later sessions. Conclusion We have introduced a new technical solution for valid, reproducible in vivo force measurements on every possible point of the stretching curve. Thus it should be possible to study the muscle contraction in vivo to the same level of accuracy as is achieved in tests with in vitro organ preparations.

    1997-01-01

    Some selected issues which are facing both operators and contractors in drilling for oil and gas, such as the allocation of risk by contract and by statute and the implementation of new technologies, were discussed. There are three varieties of written drilling contracts used in Canada: (1) day work and meterage contracts, (2) master drilling agreements, and (3) contracts that are used in construction projects that do not specifically relate to drilling. Issues relevant to the contractual allocation of risk, to implementing new drilling technologies, to reconciling contract and statute liability, and the formation of strategic alliances for mutual benefit, and the factors contributing to the success of such alliances were explored. 12 refs

    Full Text Available Changing employment relations between employees and employers due to the increasing employment flexibility have contributed to the development of a new paradigm to analyze these relations based on the concept of psychological contract. This paradigm might be particularly relevant in Poland where the employment flexibility understood as the number of workers with temporary contracts is the highest in Europe. In this paper the concept of psychological contract is presented along with the existing findings related to its range, balance and contract fulfilment vs. contract breach. The results of studies showing the differences in psychological contract of temporary and permanent workers are also presented. The majority of them indicate that psychological contracts of temporary workers are limited in their extent, less balanced and asymmetric (to workers’ disadvantage, as well as more transactional in their nature than those of permanent workers. The temporary workers’ well-being and attitudes towards work and their reaction to psychological contract breach largely depends on their preferences for this type of employment, on their qualifications and on a labor market situation.

  15. What constitutes the gas sales contract in the evolving marketplace?

    International Nuclear Information System (INIS)

    Hughes, T.M.

    1996-01-01

    A general overview of certain fundamental issues of contract law, which are relevant to gas sales transactions, was presented. Since deregulation, parties of the Canadian natural gas market are free to negotiate the terms of arrangements and contracts with any number of buyers and sellers. With deregulation also came a substantial increase in the amount of litigation regarding sales contracts. Two basic issues that should be kept in mind when negotiating any gas sales contract were letter agreements, (two versions of non-binding letters of intent), and requirement of writing. Within the requirements of writing one should be mindful of the legal implications of the fraud statutes, the Sale of Goods Act, what constitutes a sufficient note or memorandum, what constitutes the requisite signature, contracting out of the requirement of writing and signature on the mass agreement, certainty of terms, and the terms implied by legislation. It was considered advantageous for both buyers and sellers to continue to be vigilant about the contractual arrangements respecting all of their gas transactions

    Full Text Available The predominant bioserotypes of pathogenic Yersinia enterocolitica in China are 2/O: 9 and 3/O: 3; no pathogenic O: 8 strains have been found to date. Multiple-Locus Variable-Number Tandem-Repeat Analysis (MLVA based on seven loci was able to distinguish 104 genotypes among 218 pathogenic Y. enterocolitica isolates in China and from abroad, showing a high resolution. The major pathogenic serogroups in China, O: 3 and O: 9, were divided into two clusters based on MLVA genotyping. The different distribution of Y. enterocolitica MLVA genotypes maybe due to the recent dissemination of specific clones of 2/O: 9 and 3/O: 3 strains in China. MLVA was a helpful tool for bacterial pathogen surveillance and investigation of pathogenic Y. enterocolitica outbreaks.

  4. Clinical Trials With Large Numbers of Variables: Important Advantages of Canonical Analysis.

    Science.gov (United States)

    Cleophas, Ton J

    2016-01-01

    Canonical analysis assesses the combined effects of a set of predictor variables on a set of outcome variables, but it is little used in clinical trials despite the omnipresence of multiple variables. The aim of this study was to assess the performance of canonical analysis as compared with traditional multivariate methods using multivariate analysis of covariance (MANCOVA). As an example, a simulated data file with 12 gene expression levels and 4 drug efficacy scores was used. The correlation coefficient between the 12 predictor and 4 outcome variables was 0.87 (P = 0.0001) meaning that 76% of the variability in the outcome variables was explained by the 12 covariates. Repeated testing after the removal of 5 unimportant predictor and 1 outcome variable produced virtually the same overall result. The MANCOVA identified identical unimportant variables, but it was unable to provide overall statistics. (1) Canonical analysis is remarkable, because it can handle many more variables than traditional multivariate methods such as MANCOVA can. (2) At the same time, it accounts for the relative importance of the separate variables, their interactions and differences in units. (3) Canonical analysis provides overall statistics of the effects of sets of variables, whereas traditional multivariate methods only provide the statistics of the separate variables. (4) Unlike other methods for combining the effects of multiple variables such as factor analysis/partial least squares, canonical analysis is scientifically entirely rigorous. (5) Limitations include that it is less flexible than factor analysis/partial least squares, because only 2 sets of variables are used and because multiple solutions instead of one is offered. We do hope that this article will stimulate clinical investigators to start using this remarkable method.

  5. Low numbers of repeat units in variable number of tandem repeats (VNTR) regions of white spot syndrome virus are correlated with disease outbreaks.

    2012-11-01

    White spot syndrome virus (WSSV) is the most important pathogen in shrimp farming systems worldwide including the Mekong Delta, Vietnam. The genome of WSSV is characterized by the presence of two major 'indel regions' found at ORF14/15 and ORF23/24 (WSSV-Thailand) and three regions with variable number tandem repeats (VNTR) located in ORF75, ORF94 and ORF125. In the current study, we investigated whether or not the number of repeat units in the VNTRs correlates with virus outbreak status and/or shrimp farming practice. We analysed 662 WSSV samples from individual WSSV-infected Penaeus monodon shrimp from 104 ponds collected from two important shrimp farming regions of the Mekong Delta: Ca Mau and Bac Lieu. Using this large data set and statistical analysis, we found that for ORF94 and ORF125, the mean number of repeat units (RUs) in VNTRs was significantly lower in disease outbreak ponds than in non-outbreak ponds. Although a higher mean RU number was observed in the improved-extensive system than in the rice-shrimp or semi-intensive systems, these differences were not significant. VNTR sequences are thus not only useful markers for studying WSSV genotypes and populations, but specific VNTR variants also correlate with disease outbreaks in shrimp farming systems. © 2012 Blackwell Publishing Ltd.

  6. Changes in Variable Number of Tandem Repeats in 'Candidatus Liberibacter asiaticus' through Insect Transmission.

    Directory of Open Access Journals (Sweden)

    Hiroshi Katoh

    Full Text Available Citrus greening (huanglongbing is the most destructive citrus disease worldwide. The disease is associated with three species of 'Candidatus Liberibacter' among which 'Ca. Liberibacter asiaticus' has the widest distribution. 'Ca. L. asiaticus' is commonly transmitted by a phloem-feeding insect vector, the Asian citrus psyllid Diaphorina citri. A previous study showed that isolates of 'Ca. L. asiaticus' were clearly differentiated by variable number of tandem repeat (VNTR profiles at four loci in the genome. In this study, the VNTR analysis was further validated by assessing the stability of these repeats after multiplication of the pathogen upon host-to-host transmission using a 'Ca. L. asiaticus' strain from Japan. The results showed that some tandem repeats showed detectable changes after insect transmission. To our knowledge, this is the first report to demonstrate that the repeat numbers VNTR 002 and 077 of 'Ca. L. asiaticus' change through psyllid transmission. VNTRs in the recipient plant were apparently unrelated to the growing phase of the vector. In contrast, changes in the number of tandem repeats increased with longer acquisition and inoculation access periods, whereas changes were not observed through psyllid transmission after relatively short acquisition and inoculation access periods, up to 20 and 19 days, respectively.

  7. The role of collective labor contracts and individual characteristics on job satisfaction in Tuscan nursing homes.

    The role played by remuneration strategies in motivating health care professionals is one of the most studied factors. Some studies of nursing home (NH) services, while considering wages and labor market characteristics, do not explicitly account for the influence of the contract itself. This study investigates the relationship between the labor contracts applied in 62 Tuscan NHs and NH aides' job satisfaction with two aims: to investigate the impact of European contracts on employee satisfaction in health care services and to determine possible limitations of research not incorporating these contracts. We apply a multilevel model to data gathered from a staff survey administered in 2014 to all employees of 62 NHs to analyze two levels: individual and NH. Labor contracts were introduced into the model as a variable of NH. Findings show that the factors influencing nursing aides' satisfaction occur at both the individual and NH levels. Organizational characteristics explain 16% of the variation. For individual characteristics, foreign and temporary workers emerge as more satisfied than others. For NH variables, results indicate that the labor contract with the worst conditions is not associated with lower workers' satisfaction. Although working conditions play a relevant role in the job satisfaction of aides, labor contracts do not seem to affect it. Interestingly, aides of the NHs with the contract having the best conditions register a significantly lower level of satisfaction compared to the NHs with the worst contract conditions. This suggests that organizational factors such as culture, team work, and other characteristics, which were not explicitly considered in this study, may be more powerful sources of worker satisfaction than labor contracts. Our analysis has value as a management tool to consider alternative sources as well as the labor contract for employee incentives.This is an open-access article distributed under the terms of the Creative Commons

    Full Text Available The aim of this study was to investigate organisational commitment in an organisation that had recently experienced organisational restructuring (a merger. The psychological contract that exists between employees and organisations is brittle due to many organisational changes that stem from organisational restructuring.  When psychological contracts are breached, employees may experience reduced commitment to the organisation.  The target population for this study consisted of all employees working at three recently-merged higher education institutions in the Nelson Mandela Metropolis (n=100 and a self-administered questionnaire was distributed amongst staff.  The results indicated that an increase in the number of positive human resource management (HRM practices reported by respondents correlated with a decrease in violation and breach of the psychological contract, despite organisational restructuring.  It was further revealed that effective management of the psychological contract is crucial during organisational restructuring, in order to maintain the commitment and loyalty of employees.

    it can be characterized as an uncertain variable. Moreover, the employee's effort is unobservable to the employer, and the employee can select her effort level to maximize her utility. Thus, an uncertain wage contract model with adverse selection and moral hazard is established to maximize the employer's expected profit. And the model analysis mainly focuses on the equivalent form of the proposed wage contract model and the optimal solution to this form. The optimal solution indicates that both the employee's effort level and the wage increase with the employee's ability. Lastly, a numerical example is given to illustrate the effectiveness of the proposed model.

    A general scheme for constructing polytopes is implemented here specifically for the classes of the most important 3D polytopes, namely those whose vertices are labeled by integers relative to a particular basis, here called the ω-basis. The actual number of non-isomorphic polytopes of the same group has no limit. To put practical bounds on the number of polytopes to consider for each group we limit our consideration to polytopes with dominant point (vertex) that contains only nonnegative integers in ω-basis. A natural place to start the consideration of polytopes from is the generic dominant weight which were all three coordinates are the lowest positive integer numbers. Contraction is a continuous change of one or several coordinates to zero.

  15. Performance-based contracting for maintaining transportation assets with emphasis on bridges

    2017-01-01

    Full Text Available With a large number of aging transportation infrastructure assets in North America and the growing problem of deterioration across the globe, managing these assets have been the subject of ongoing research. There is an overwhelming amount of maintenance and rehabilitation works to be done and selecting a suitable maintenance, repair or replacement (MRR strategy is one of the most challenging tasks for decision makers. Limited budget and resources are even making the decision making process more challenging. Maintaining infrastructure to the highest possible condition while investing the minimal amount of money has promoted innovative contracting approaches. Transportation agencies have increased private sector involvement through long term performance-based maintenance contracts or what is called Performance-Based Contracting. PBC is a type of contract that pays a contractor based on the results achieved, not on the methods for performing the maintenance work. By looking into the literature, it is observed that agencies are expanding the amount of contracting they do in order to maintain and achieve a better standard of infrastructure facilities. Therefore, the objective of this paper is to study and review performance-based contracting for transportation infrastructure with emphasis on bridge assets.

    The European system for cardiac operative risk evaluation (EuroSCORE) is currently used in many institutions and is considered a reference tool in many countries. We hypothesised that too many variables were included in the EuroSCORE using limited patient series. We tested different models using a limited number of variables. A total of 11150 adult patients undergoing cardiac operations at our institution (2001-2007) were retrospectively analysed. The 17 risk factors composing the EuroSCORE were separately analysed and ranked for accuracy of prediction of hospital mortality. Seventeen models were created by progressively including one factor at a time. The models were compared for accuracy with a receiver operating characteristics (ROC) analysis and area under the curve (AUC) evaluation. Calibration was tested with Hosmer-Lemeshow statistics. Clinical performance was assessed by comparing the predicted with the observed mortality rates. The best accuracy (AUC 0.76) was obtained using a model including only age, left ventricular ejection fraction, serum creatinine, emergency operation and non-isolated coronary operation. The EuroSCORE AUC (0.75) was not significantly different. Calibration and clinical performance were better in the five-factor model than in the EuroSCORE. Only in high-risk patients were 12 factors needed to achieve a good performance. Including many factors in multivariable logistic models increases the risk for overfitting, multicollinearity and human error. A five-factor model offers the same level of accuracy but demonstrated better calibration and clinical performance. Models with a limited number of factors may work better than complex models when applied to a limited number of patients. Copyright (c) 2009 European Association for Cardio-Thoracic Surgery.

  8. Rheosensing by impulsive cells at intermediate Reynolds numbers

    Science.gov (United States)

    Mathijssen, Arnold; Bhamla, Saad; Prakash, Manu

    2017-11-01

    For aquatic organisms, mechanical signals are often carried by the surrounding liquid, through viscous and inertial forces. Here we consider a unicellular yet millimetric ciliate, Spirostomum ambiguum, as a model organism to study hydrodynamic sensing. This protist typically swims at moderate Reynolds numbers, Re 100 during impulsive contractions where its elongated body recoils within milliseconds. First, using high-speed PIV and an electrophysiology setup, we deliver controlled voltage pulses to induce these rapid contractions and visualise the vortex flows generated thereby. By comparing these measurements with CFD simulations the range of these hydrodynamic ``signals'' is characterized. Second, we probe the mechano-sensing of the organism with externally applied flows and find a critical shear rate necessary to trigger a contraction. The combination of high Re flow generation and rheosensing could facilitate intercellular communication over large distances. Please also see our other talk ``Collective hydrodynamic communication through ultra-fast contractions''.

  11. The effects of variability on the number-flux-density relationship for radio sources

    International Nuclear Information System (INIS)

    Schuch, N.J.

    1981-01-01

    It has been known for some time that the number-flux-density relationship for radio sources requires a population of sources whose properties evolve with cosmological epoch, at least in models where the redshifts are all taken to be cosmological. In particular, the surveys made at metre wavelengths show, for bright sources, a slope of the log N -log S curve which is steeper than the value -1.5 expected in a static, non-evolving Euclidean universe. Here, N is the number of radio sources brighter than flux density S. Expansion without evolution in conventional geometrical models predicts slopes flatter than -1.5. If the radio survey is carried out at higher frequencies (typically 2.7 or 5 GHz - 11 or 6 cm wavelength), the slope of the log N -log S curve is steeper than -1.5 but not so steep as the slopes found for the low-frequency surveys. Many of the sources found in high-frequency surveys have radio spectra with relatively higher flux-densities in the centimetre range; these sources are frequently variable at high frequencies, with time-scales from a month or two upwards. Some possible effects of the variations on the observed counts of radio sources are considered. (author)

  12. THE PSYCHOLOGICAL CONTRACT

    Directory of Open Access Journals (Sweden)

    Blanca Giorgiana GRAMA

    2015-04-01

    Full Text Available The psychological contract became known as a research paradigm within corporate research, providing a broad framework which explains the employee-company relations. Despite all this, there are still many debates on the concept and a series of criticism were expressed that led to the necessity of some more rigorous theoretical and empirical analysis. The psychological contract refers to the unwritten, implicit expectations that employees have from the company and vice versa; it is that which defines the things the employee expects from the employer. Consequently, each of the parties involved in the contract may have different perceptions on these commitments and obligations. Thus the psychological contract may be regarded as an exchange relation between the employer and the employee. Breaking the psychological contract affects the performance, the morale, and the motivation of the staff in a negative manner. The information presented in this paper is intended to contribute to the theoretical and methodological development of the concept.

    2017-03-01

    This study aimed (1) to profile the plantar loading characteristics when performing the basketball lay-up in a realistic setting and (2) to determine the number of trials necessary to establish a stable mean for plantar loading variables during the lay-up. Thirteen university male basketball players [age: 23.0 (1.4) years, height: 1.75 (0.05) m, mass: 68.4 (8.6) kg] performed ten successful basketball lay-ups from a stationary position. Plantar loading variables were recorded using the Novel Pedar-X in-shoe system. Loading variables including peak force, peak pressure, and pressure-time integral were extracted from eight foot regions. Performance stability of plantar loading variables during the take-off and landing steps were assessed using the sequential averaging technique and intra-class correlation coefficient (ICC). High plantar loadings were experienced at the heel during the take-off steps, and both the heel and forefoot regions upon landing. The sequential estimation technique revealed a five-eight trial range to achieve a stable mean across all plantar loading variables, whereas ICC analysis was insensitive to inter-trial differences of repeated lay-up performances. Future studies and performance evaluation protocols on plantar loading during basketball lay-ups should include at least eight trials to ensure that the measurements obtained are sufficiently stable.

    2015-01-01

    The purpose of this paper is to explore the readiness of contracted and non-contracted first-level healthcare facilities in Pakistan to deliver quality maternal and neonatal health (MNH) care. A balanced scorecard (BSC) was used as the assessment framework. Using a cross-sectional study design, two rural health centers (RHCs) contracted out to Aga Khan Health Service, Pakistan were compared with four government managed RHCs. A BSC was designed to assess RHC readiness to deliver good quality MNH care. In total 20 indicators were developed, representing five BSC domains: health facility functionality, service provision, staff capacity, staff and patient satisfaction. Validated data collection tools were used to collect information. Pearson χ2, Fisher's Exact and the Mann-Whitney tests were applied as appropriate to detect significant service quality differences among the two facilities. Contracted facilities were generally found to be better than non-contracted facilities in all five BSC domains. Patients' inclination for facility-based delivery at contracted facilities was, however, significantly higher than non-contracted facilities (80 percent contracted vs 43 percent non-contracted, p=0.006). The study shows that contracting out initiatives have the potential to improve MNH care. This is the first study to compare MNH service delivery quality across contracted and non-contracted facilities using BSC as the assessment framework.

    2006-05-01

    Seasonal and annual movements of Australian waterbirds are generally more complex than those of their Northern Hemisphere counterparts, and long-term data are needed to understand their relationships with climatic variables. This paper explores a long-term (1973 2002) set of waterbird counts from coastal Victoria and relates them to climatic data at local and continental scales. Three species (Black Swan Cygnus atratus, White-faced Heron Egretta novaehollandiae and Grey Teal Anas gracilis) were chosen for this analysis. Black Swans have large local breeding populations near the study region; White-faced Herons have smaller local breeding populations and Grey Teal breed extensively in ephemeral inland floodplains, such as those in the Murray-Darling Basin. All showed significant relationships with streamflow, regional rainfall and the Southern Oscillation Index (SOI) at appropriate scales and time-lags, with streamflow explaining the most variance. Black Swans showed a strong seasonal cycle in abundance and local climate variables had the greatest influence on the counts. Numbers were positively correlated with streamflow in southern Victoria three to six seasons before each count. Broader-scale climatic patterns were more important for the other two species. Numbers of White-faced Herons were positively correlated with streamflow or rainfall over various parts of Australia seven to nine seasons before each count. Numbers of Grey Teal showed weak seasonal cycles, and were negatively correlated with rainfall in Victoria or the Murray-Darling Basin in the seasons before or during each count, and positively with streamflow in the Murray-Darling Basin 15 18 months before each count.

  3. The Structural Model of Psychological Contract Violation, Organizational Commitment, Turnover, Job Satisfaction and Deviant Behaviors

    Full Text Available This research was conducted with the purpose of studying the structural model of the relationships of psychological contract violation with organizational commitment, turnover, job satisfaction and deviant behaviors. Research method was correlation and the statistical population were male employees of an industrial company in Shiraz city, from among which 300 employees were selected using convenience sampling. Assessment instruments consisted of Psychological Contract Violation Questionnaire (Tekleab etal, 2005, Organizational Commitment Questionnaire (Speier & Vankatesh, 2002, Job Satisfaction Questionnaire (Spector, 1985, Turnover Questionnaire (Tekleab etal, 2005 and Deviant Behavior Questionnaire (Bennett & Robinson, 2000. Data was analyzed using Pearson’s correlation coefficient, structure equation modeling (SEM and mediation analysis. Findings showed that psychological contract violation explained 7.1 percent of organizational commitment variance, organizational commitment and job satisfaction explained 16.7 percent of turnover variance, organizational commitment explained 20.3 percent of job satisfaction variance and turnover explained 4.3 percent of deviant behavior variance. Mediation analysis showed that organizational commitment played the complete mediator variable in the relation of psychological contract violation with job satisfaction and job satisfaction was the partial mediator variable in the relation of organizational commitment with turnover. Finally with regard to the limitation of generalization of current research results it is suggested to industrial organizations that they should not violate their obligations to employees in anyway.

    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.

    The PER3 gene is one of the clock genes, which function in the core mammalian molecular circadian system. A variable number of tandem repeats (VNTR) locus in the 18th exon of this gene has been strongly associated to circadian rhythm phenotypes and sleep organization in humans, but it has not been identified in other mammals except primates. To better understand the evolution and the placement of the PER3 VNTR in a phylogenetical context, the present study enlarges the investigation about the presence and the structure of this variable region in a large sample of primate species and other mammals. The analysis of the results has revealed that the PER3 VNTR occurs exclusively in simiiforme primates and that the number of copies of the primitive unit ranges from 2 to 11 across different primate species. Two transposable elements surrounding the 18th exon of PER3 were found in primates with published genome sequences, including the tarsiiforme Tarsius syrichta, which lacks the VNTR. These results suggest that this VNTR may have evolved in a common ancestor of the simiiforme branch and that the evolutionary copy number differentiation of this VNTR may be associated with primate simiiformes sleep and circadian phenotype patterns.

  9. Can De Sitter spacetime be a final state of the contracting universe

    International Nuclear Information System (INIS)

    Berezin, V.A.

    1984-01-01

    This chapter attempts to phenomenologically describe the final stage of the Universe contraction. A model equation of state is used to demonstrate that during a cosmological contraction a de Sitter spacetime may be produced. It is shown that a equilibrium thermodynamic description of the matter in cosmological models leads to the absence of particle creation. It is proposed that these nonequilibrium processes be taken into account by introducing a new additional thermodynamic variable showing the explicit time dependence of all thermodynamic potentials into the thermodynamic relations. The spacetime is assumed to be homogeneous and isotropic, and the energy momentum tensor includes not only the energy density and pressure for the matter and radiation, but it also includes contributions due to vacuum polarization by correspondent fields. It is demonstrated that it is possible to reach in principle the de Sitter spacetime as the limit of the contraction

    The Work and Minor Work contracts are all of the result-oriented type. The work is specified by CERN and the contractor is given full responsibility for its performance. The contracts are thus very similar to supply contracts. The re-tendering of the existing contracts is almost complete, except for some building maintenance contracts. A new cycle of re-tendering for some activities will be launched in the next twelve months. The total estimated expenditure in the year 2000 for the contracts referred to in this document is 27 750 000 Swiss francs at 1999 prices.

    Full Text Available A chattel mortgage contract is the expression of a real guarantee that gives the creditor precedence over other creditors, in addition to the general pledge upon the belongings of the debtor. It refers to the sale of mortgaged movable assets, exclusively or prioritized in favor of the mortgaging creditor, in case the debtor does not comply with his / her commitments, under the signed mortgage contract. Beginning from this purpose, shared by both sides (as the chattel mortgage contract is synallagmatic, in case the debtor is unable to fulfill his / her commitments, the sides reach a situation of enforcement of the signed chattel mortgage contract. Given the legal status of the chattel mortgage contract [Art. 2387-2477 Noul Cod Civil , Universul Juridic, Bucureşti, 2016, ISBN 978-606-673-792-0], the principle of binding force of the contract and the principle according to which signed legal conventions will entail legal effects, the Romanian law maker developed the proper legal framework for the enforcement of the chattel mortgage contract.

  6. Safety and health education and training of contract workers in nuclear power plants

    2008-01-01

    Nuclear power plants have used many contract workers. Their safety and health conditions are very important in Japan. Several amendments, which deregulate temporary personnel service and employment agency markets, have been done in recent years. The number of contract and temporary help agency workers have been rapidly increasing especially since the 1990s. As a result, ensuring the level of safety and health education and training of workers becomes a serious problem. This paper examines the possibility that the level of safety training of the contract workers is less than that of the direct-hire employees in nuclear power plants. We show that (1) the use of contract workers could be less efficient for ensuring the level of safety training, and (2) nuclear power plants still use contract workers in some situations in spite of the loss of efficiency. We also study legislations and past cases relating to nuclear power generation. We find that there are some structural problems that might make the contract workers less trained. (author)

    Discrimination against people with mental illness is rife across the globe. Among different types of discrimination is the policy in many countries where persons with mental illness are forbidden to inherit property, and they are not able to enter into a contract in a large number of countries. Using various databases, legislations dealing with law of contract, law of succession/inheritance, and law relating to testamentary capacity (wills) of all UN Member states (193 countries) were studied. With respect to federal countries, the laws of the most populous state as a representative state in the respective country were studied. Only 40 Member States (21%) recognize/allow persons with mental health problems to enter into contracts. Of these, however, only 16 Member States (9%) recognize the right of persons with mental health problems to enter into a contract without any restrictions. The remaining 24 Member States (12%) allow a contract entered into by a person with mental health problems to be invalidated under certain conditions. These countries also make the validity of the contract subject to the capacity to consent or based on the level of understanding of the person with mental health problems. They may allow persons with mental health problems to enter into contracts only for transactions of an insignificant nature or of personal rights. Only 9% of the countries allow people with mental illness to enter into contracts in an unrestricted way. Furthermore, there remain variations between high income and low income states. In spite of international laws in many countries, laws remain discriminatory.

    Full Text Available A large amount of effort is spent on forecasting the outcome of sporting events. Moreover, there are large quantities of data regarding the outcomes of sporting events and the factors which are assumed to contribute to those outcomes. In this paper we tried to predict the success of nations at the Asian Games through macro-economic, political, social and cultural variables. we used the information of variables include urban population, Education Expenditures, Age Structure, GDP Real Growth Rate, GDP Per Capita, Unemployment Rate, Population, Inflation Average, current account balance, life expectancy at birth and Merchandise Trade for all of the participating countries in Asian Games from 1970 to 2006 in order to build the model and then this model was tested by the information of variables in 2010. The prediction is based on the number of total medals acquired each country. In this research we used WEKA software that is a popular suite of machine learning software written in Java. The value of correlation coefficient between the predicted and original ranks is 90.42%. Neural Network Model, between 28 countries mentioned, predicts their ranks according to the maximum difference between predicted and original ranks of 19 countries (67.85% is 3, the maximum difference between predicted and original ranks of 8 countries (28.57% is between 4 to 6 and the difference between predicted and original ranks of 1 countries (3.57% is more than 6.

  10. Residential energy contracts and the 28 day rule

    International Nuclear Information System (INIS)

    Littlechild, Stephen

    2006-01-01

    What measures are needed to protect customers when a utility market is first opened to competition? In the UK, residential (domestic) customers must be able to terminate energy contracts at 28 days' notice. This rule was introduced as a transitional protection for customers and for competition. However, the regulatory justification for the rule seems to have evolved over time. Removing the rule could have a number of advantages, including the development of fixed-price fixed-term contracts. The advantages of retaining the rule are questionable. In other retail sectors there is no regulatory concern or requirement of this kind. UK electricity suppliers have begun to offer capped prices for specified periods of time, suggesting that there is a growing customer demand for this. Fixed-price fixed-term contracts are a common form of competition in Scandinavia. The 28 day rule no longer seems necessary to protect customers and is more likely to distort than to protect competition. In retrospect, it would have been preferable not to introduce the rule in the first place. (author)

  11. Explaining the contract terms of energy performance contracting in China: The importance of effective financing

    Li, Yan; Qiu, Yueming; Wang, Yi David

    2014-01-01

    Energy service company (“ESCO”) uses Energy Performance Contracting (“EPC”) to provide energy-saving services to its clients. Under an EPC, both ESCO and the client invest in the energy efficiency measures, according to a negotiated share of investment. Within the length of the contract, the ESCO and its client divide up the saved energy bill according to a negotiated share. Once the contract expires, the client claims all of the saved energy bills if the energy efficiency measures still last. Different EPC projects have different contract terms, including total investment, share of investment and length of contract. These contract terms directly determine the resulted energy savings. Thus it is essential and important to look at how these contract terms are formed and what are the major influencing factors. This paper first builds a theoretical bargain model between ESCO and its client to find out the structural relationship among these contract terms. Then, using the information of about 140 EPC contracts in China in 2010 and 2011, the paper empirically estimates the impacts of various factors on the contract terms and the resulted energy savings. We find that cost of capitals for ESCOs and the clients, especially for ESCOs, is a major factor influencing contract terms and the resulted energy savings. Thus providing effective financing is critical for the development of EPC in China. - Highlights: • We build a theoretical bargain model between an ESCO and its client. • We empirically quantify the impacts of various factors on EPC contract terms. • Cost of capital is a key factor determining EPC contract terms. • Providing effective financing, especially for ESCOs is important

  13. Simulation of a chain of collapsible contracting lymphangions with progressive valve closure.

    Bertram, C D; Macaskill, C; Moore, J E

    2011-01-01

    The aim of this investigation was to achieve the first step toward a comprehensive model of the lymphatic system. A numerical model has been constructed of a lymphatic vessel, consisting of a short series chain of contractile segments (lymphangions) and of intersegmental valves. The changing diameter of a segment governs the difference between the flows through inlet and outlet valves and is itself governed by a balance between transmural pressure and passive and active wall properties. The compliance of segments is maximal at intermediate diameters and decreases when the segments are subject to greatly positive or negative transmural pressure. Fluid flow is the result of time-varying active contraction causing diameter to reduce and is limited by segmental viscous and valvular resistance. The valves effect a smooth transition from low forward-flow resistance to high backflow resistance. Contraction occurs sequentially in successive lymphangions in the forward-flow direction. The behavior of chains of one to five lymphangions was investigated by means of pump function curves, with variation of valve opening parameters, maximum contractility, lymphangion size gradation, number of lymphangions, and phase delay between adjacent lymphangion contractions. The model was reasonably robust numerically, with mean flow-rate generally reducing as adverse pressure was increased. Sequential contraction was found to be much more efficient than synchronized contraction. At the highest adverse pressures, pumping failed by one of two mechanisms, depending on parameter settings: either mean leakback flow exceeded forward pumping or contraction failed to open the lymphangion outlet valve. Maximum pressure and maximum flow-rate were both sensitive to the contractile state; maximum pressure was also determined by the number of lymphangions in series. Maximum flow-rate was highly sensitive to the transmural pressure experienced by the most upstream lymphangions, suggesting that many

    Halling Shirley M

    2003-07-01

    Full Text Available Abstract Background Currently, there are very few tools available for subtyping Brucella isolates for epidemiological trace-back. Subtyping is difficult because of the genetic homogeneity within the genus. Sequencing of the genomes from three Brucella species has facilitated the search for DNA sequence variability. Recently, hypervariability among short tandem repeat sequences has been exploited for strain-typing of several bacterial pathogens. Results An eight-base pair tandem repeat sequence was discovered in nine genomic loci of the B. abortus genome. Eight loci were hypervariable among the three Brucella species. A PCR-based method was developed to identify the number of repeat units (alleles at each locus, generating strain-specific fingerprints. None of the loci exhibited species- or biovar-specific alleles. Sometimes, a species or biovar contained a specific allele at one or more loci, but the allele also occurred in other species or biovars. The technique successfully differentiated the type strains for all Brucella species and biovars, among unrelated B. abortus biovar 1 field isolates in cattle, and among B. abortus strains isolated from bison and elk. Isolates from the same herd or from short-term in vitro passage exhibited little or no variability in fingerprint pattern. Sometimes, isolates from an animal would have multiple alleles at a locus, possibly from mixed infections in enzootic areas, residual disease from incomplete depopulation of an infected herd or molecular evolution within the strain. Therefore, a mixed population or a pool of colonies from each animal and/or tissue was tested. Conclusion This paper describes a new method for fingerprinting Brucella isolates based on multi-locus characterization of a variable number, eight-base pair, tandem repeat. We have named this technique "HOOF-Prints" for Hypervariable Octameric Oligonucleotide Finger-Prints. The technique is highly discriminatory among Brucella species, among

  16. Automatic Conflict Detection on Contracts

    Science.gov (United States)

    Fenech, Stephen; Pace, Gordon J.; Schneider, Gerardo

    Many software applications are based on collaborating, yet competing, agents or virtual organisations exchanging services. Contracts, expressing obligations, permissions and prohibitions of the different actors, can be used to protect the interests of the organisations engaged in such service exchange. However, the potentially dynamic composition of services with different contracts, and the combination of service contracts with local contracts can give rise to unexpected conflicts, exposing the need for automatic techniques for contract analysis. In this paper we look at automatic analysis techniques for contracts written in the contract language mathcal{CL}. We present a trace semantics of mathcal{CL} suitable for conflict analysis, and a decision procedure for detecting conflicts (together with its proof of soundness, completeness and termination). We also discuss its implementation and look into the applications of the contract analysis approach we present. These techniques are applied to a small case study of an airline check-in desk.

  17. DNA fingerprinting of Mycobacterium leprae strains using variable number tandem repeat (VNTR) - fragment length analysis (FLA).

    The study of the transmission of leprosy is particularly difficult since the causative agent, Mycobacterium leprae, cannot be cultured in the laboratory. The only sources of the bacteria are leprosy patients, and experimentally infected armadillos and nude mice. Thus, many of the methods used in modern epidemiology are not available for the study of leprosy. Despite an extensive global drug treatment program for leprosy implemented by the WHO, leprosy remains endemic in many countries with approximately 250,000 new cases each year. The entire M. leprae genome has been mapped and many loci have been identified that have repeated segments of 2 or more base pairs (called micro- and minisatellites). Clinical strains of M. leprae may vary in the number of tandem repeated segments (short tandem repeats, STR) at many of these loci. Variable number tandem repeat (VNTR) analysis has been used to distinguish different strains of the leprosy bacilli. Some of the loci appear to be more stable than others, showing less variation in repeat numbers, while others seem to change more rapidly, sometimes in the same patient. While the variability of certain VNTRs has brought up questions regarding their suitability for strain typing, the emerging data suggest that analyzing multiple loci, which are diverse in their stability, can be used as a valuable epidemiological tool. Multiple locus VNTR analysis (MLVA) has been used to study leprosy evolution and transmission in several countries including China, Malawi, the Philippines, and Brazil. MLVA involves multiple steps. First, bacterial DNA is extracted along with host tissue DNA from clinical biopsies or slit skin smears (SSS). The desired loci are then amplified from the extracted DNA via polymerase chain reaction (PCR). Fluorescently-labeled primers for 4-5 different loci are used per reaction, with 18 loci being amplified in a total of four reactions. The PCR products may be subjected to agarose gel electrophoresis to verify the

    2008-05-01

    Variable-number-of-tandem-repeats (VNTR) markers are increasingly being used in population genetic studies of bacteria. They were recently developed for Pasteuria ramosa, an endobacterium that infects Daphnia species. In the present study, we genotyped P. ramosa in 18 infected hosts from the United Kingdom, Belgium, and two lakes in the United States using seven VNTR markers. Two Daphnia species were collected: D. magna and D. dentifera. Six loci showed length polymorphism, with as many as five alleles identified for a single locus. Similarity coefficient calculations showed that the extent of genetic variation between pairs of isolates within populations differed according to the population, but it was always less than the genetic distances among populations. Analysis of the genetic distances performed using principal component analysis revealed strong clustering by location of origin, but not by host Daphnia species. Our study demonstrated that the VNTR markers available for P. ramosa are informative in revealing genetic differences within and among populations and may therefore become an important tool for providing detailed analysis of population genetics and epidemiology.

    Karen E. C. Levy

    2017-02-01

    Full Text Available This paper critiques blockchain-based “smart contracts,” which aim to automatically and securely execute obligations without reliance on a centralized enforcement authority. Though smart contracts do have some features that might serve the goals of social justice and fairness, I suggest that they are based on a thin conception of what law does, and how it does it. Smart contracts focus on the technical form of contract to the exclusion of the social contexts within which contracts operate, and the complex ways in which people use them. In the real world, contractual obligations are enforced through all kinds of social mechanisms other than formal adjudication—and contracts serve many functions that are not explicitly legal in nature, or even designed to be formally enforced. I describe three categories of contracting practices in which people engage (the inclusion of facially unenforceable terms, the inclusion of purposefully underspecified terms, and willful nonenforcement of enforceable terms to illustrate how contracts actually “work.” The technology of smart contracts neglects the fact that people use contracts as social resources to manage their relations. The inflexibility that they introduce, by design, might short-circuit a number of social uses to which law is routinely put. Therefore, I suggest that attention to the social and relational contexts of contracting are essential considerations for the discussion, development, and deployment of smart contracts.

    2012-03-01

    The ability to modulate the myofibroblast phenotype will have important implications in wound healing, aging and cancer development. Our objective was to determine whether irradiation using a 980-nm laser affects the presence of myofibroblasts and cellular contractility using an attached collagen lattice model. Fibroblasts in type I collagen lattices were allowed to generate tension for 5 days in the presence or absence of laser light stimulation on day 4. Immunostaining was used to determine the total number of cells in a representative image and percentage of myofibroblasts in the same image; tension generation was determined by releasing tension and measuring diameter change over time. One treatment demonstrated a slight lattice contraction increase over control, correlated with increased cell number. Myofibroblast percentage was low and was not correlated with lattice contraction. More experiments are necessary due to limited sample size and lack of large deviations from the control.

    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)

  11. Analysis of foreign petroleum contracts

    International Nuclear Information System (INIS)

    Moran, S.S.

    1991-01-01

    Most foreign exploration and production contracts are of two basic types: Production-Sharing contracts in which a portion of oil revenues, 'cost oil,' is available to the contractor for recoupment of exploration and production costs with the remainder, 'profit oil,' being shared according to an agreed-upon formula, and the familiar Tax-Royalty contract in which a share of petroleum revenues goes to the host country 'off the top' as royalties, and operating profits are taxed at the going rate. Bottom line splits of profits between host governments and contractors, which are approximately 50-50 in the United States, are typically in the 60-40 to 85-15 range elsewhere, with lower profit shares being offset by the higher volume potential and lower costs that may be associated with less mature exploration areas. Foreign contract qualities can be grossly compared by walking typical field models through the contracts to arrive at the bottom line profit splits. Variations within the contract forms include government participation, sliding scale contract elements, special taxes related to rates of return, etc. Often, contract terms are subject to negotiation and the tradeoffs between contract elements must be understood. Contract life, amortization schedules, fund repatriation, currency exchange rates, and the interaction of foreign and United States tax regimens are among the other factors that must be considered. Final decisions on foreign ventures must combine consideration of contracts, economic projections, hydrocarbon volumes, exploration cost estimates, and the estimated probability of success into an overall project assessment

    Full Text Available Public procurement may be examined from different perspectives. Using the Czech Republic as an example, this study is devoted to examining the impact of decisions made by the contracting authority regarding a public tender on the tender process itself and on the outcomes of the tender. The contracting authority addresses a number of decision-making issues regarding public procurements. For example, it needs to decide between two types of criteria (choosing between a single-criterion evaluation or rather opting for several evaluation criteria. At the same time, the authority is free to choose among different types of award procedures while adhering to certain restrictions imposed by the Act on Public Contracts. Using a sample of 1,027 construction work contracts awarded in the Czech Republic, the study examines, in more detail, the impacts of individual choices made by the contracting authority (namely the type of evaluation criteria chosen and the type of procedure for awarding contracts on the estimated and final price of public contracts. Recommendations on how to streamline the process of public procurement can be drawn from conclusions from the empirical analysis.

  14. An unsatisfactory contract policy

    CERN Multimedia

    Association du personnel

    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...

    2014-01-01

    . The seminal work by Peyton-Jones and Eber on financial contracts shows how an algebraic approach to contract specification can be used for valuation of contracts (when combined with a model of the underlying observables) and for managing how contracts evolve under so-called fixings and decision......-taking, with the contracts eventually evaporating into the empty contract, for which no party have further obligations. The ideas have emerged into Eber's company LexiFi, which has become a leading software provider for a range of financial institutions, with all contract management operations centralised around a domain......Banks and financial institutions nowadays often use domain-specific languages (DSLs) for describing complex financial contracts, in particular, for specifying how asset transfers for a specific contract depend on underlying observables, such as interest rates, currency rates, and stock prices...

  1. Variable Copy Number, Intra-Genomic Heterogeneities and Lateral Transfers of the 16S rRNA Gene in Pseudomonas

    2012-01-01

    Even though the 16S rRNA gene is the most commonly used taxonomic marker in microbial ecology, its poor resolution is still not fully understood at the intra-genus level. In this work, the number of rRNA gene operons, intra-genomic heterogeneities and lateral transfers were investigated at a fine-scale resolution, throughout the Pseudomonas genus. In addition to nineteen sequenced Pseudomonas strains, we determined the 16S rRNA copy number in four other Pseudomonas strains by Southern hybridization and Pulsed-Field Gel Electrophoresis, and studied the intra-genomic heterogeneities by Denaturing Gradient Gel Electrophoresis and sequencing. Although the variable copy number (from four to seven) seems to be correlated with the evolutionary distance, some close strains in the P. fluorescens lineage showed a different number of 16S rRNA genes, whereas all the strains in the P. aeruginosa lineage displayed the same number of genes (four copies). Further study of the intra-genomic heterogeneities revealed that most of the Pseudomonas strains (15 out of 19 strains) had at least two different 16S rRNA alleles. A great difference (5 or 19 nucleotides, essentially grouped near the V1 hypervariable region) was observed only in two sequenced strains. In one of our strains studied (MFY30 strain), we found a difference of 12 nucleotides (grouped in the V3 hypervariable region) between copies of the 16S rRNA gene. Finally, occurrence of partial lateral transfers of the 16S rRNA gene was further investigated in 1803 full-length sequences of Pseudomonas available in the databases. Remarkably, we found that the two most variable regions (the V1 and V3 hypervariable regions) had probably been laterally transferred from another evolutionary distant Pseudomonas strain for at least 48.3 and 41.6% of the 16S rRNA sequences, respectively. In conclusion, we strongly recommend removing these regions of the 16S rRNA gene during the intra-genus diversity studies. PMID:22545126

  2. Contraction rate, flow modification and bed layering impact on scour at the elliptical guide banks

    2017-10-01

    Flow contraction by the bridge crossing structures, intakes, embankments, piers, abutments and guide banks leads to general scour and the local scour in the vicinity of the structures. Local scour is depending on flow, river bed and structures parameters and correct understanding of the impact of each parameter can reduce failure possibility of the structures. The paper explores hydraulic contraction, the discharge redistribution between channel and floodplain during the flood, local flow modification and river bed layering on depth, width and volume of scour hole near the elliptical guide banks on low-land rivers. Experiments in a flume, our method for scour calculation and computer modelling results confirm a considerable impact of the contraction rate of the flow, the discharge redistribution between channel and floodplain, the local velocity, backwater and river bed layering on the depth, width, and volume of scour hole in steady and unsteady flow, under clear water condition. With increase of the contraction rate of the flow, the discharge redistribution between channel and floodplain, the local velocity, backwater values, the scour depth increases. At the same contraction rate, but at a different Fr number, the scour depth is different: with increase in the Fr number, the local velocity, backwater, scour depth, width, and volume is increasing. Acceptance of the geometrical contraction of the flow, approach velocity and top sand layer of the river bed for scour depth calculation as accepted now, may be the reason of the structures failure and human life losses.

  7. 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.

  17. nth roots of normal contractions

    Given a complex separable Hilbert space H and a contraction A on H such that A n , n≥2 some integer, is normal it is shown that if the defect operator D A = (1 - A * A) 1/2 is of the Hilbert-Schmidt class, then A is similar to a normal contraction, either A or A 2 is normal, and if A 2 is normal (but A is not) then there is a normal contraction N and a positive definite contraction P of trace class such that parallel to A - N parallel to 1 = 1/2 parallel to P + P parallel to 1 (where parallel to · parallel to 1 denotes the trace norm). If T is a compact contraction such that its characteristics function admits a scalar factor, if T = A n for some integer n≥2 and contraction A with simple eigen-values, and if both T and A satisfy a ''reductive property'', then A is a compact normal contraction.

  18. Options: the value of flexibilities in long term uranium contracts

    International Nuclear Information System (INIS)

    Major-Sosias, M.A.

    1996-01-01

    It has been commonplace for uranium suppliers to offer utilities long-term contracts with significant quantity flexibilities. These are attractive to the utility for which the consumption of fuel is dependent on variable reactor performance and have given the suppliers an additional competitive tool. The return to a uranium market in which near-term supply is likely to be tight is a disincentive to suppliers to offer new contracts with flexibilities. Typical recent flexibility offers have been significantly less generous than in the past. A methodology is outlined which can be used to give a theoretical estimate of the value of the flexibility provision to the supplier and buyer. It is based on the similarity between flexibility provision and option contracts in the securities and commodity markets. By regarding flexibilities as ''embedded options'' it is possible to apply to them the Black-Scholes option pricing formula as long as the necessary inputs, such as the price of uranium, the loan rate and the volatility, are available. The formula does have its shortfalls, however; in particular, it cannot incorporate the political perturbations that are continually taking place in the uranium industry. (13 figures, 15 references).

    Full Text Available Abstract Background Multilocus sequence typing (MLST is currently the reference method for genotyping Streptococcus agalactiae strains, the leading cause of infectious disease in newborns and a major cause of disease in immunocompromised children and adults. We describe here a genotyping method based on multiple locus variable number of tandem repeat (VNTR analysis (MLVA applied to a population of S. agalactiae strains of various origins characterized by MLST and serotyping. Results We studied a collection of 186 strains isolated from humans and cattle and three reference strains (A909, NEM316 and 2603 V/R. Among 34 VNTRs, 6 polymorphic VNTRs loci were selected for use in genotyping of the bacterial population. The MLVA profile consists of a series of allele numbers, corresponding to the number of repeats at each VNTR locus. 98 MLVA genotypes were obtained compared to 51 sequences types generated by MLST. The MLVA scheme generated clusters which corresponded well to the main clonal complexes obtained by MLST. However it provided a higher discriminatory power. The diversity index obtained with MLVA was 0.960 compared to 0.881 with MLST for this population of strains. Conclusions The MLVA scheme proposed here is a rapid, cheap and easy genotyping method generating results suitable for exchange and comparison between different laboratories and for the epidemiologic surveillance of S. agalactiae and analyses of outbreaks.

    The report surveys the central points in the literature about contracts on geographical price differences and transmission rights in the power market. It is commonly believed that such contracts may reduce market power and contribute to better network investments. The theoretical debate is in part unfinished and largely based on very stylised assumptions. There is some indication that such contracts may not be very useful in practice. But they may be useful in some cases, perhaps in particular when power is transported outside limited surplus areas and for certain investment decisions where there is no systems operator with a natural responsibility

  3. Perceived Effects of Prevalent Errors in Contract Documents on Construction Projects

    2018-03-01

    Full Text Available One of the highly rated causes of poor performance is errors in contract documents. The objectives of this study are to investigate the prevalent errors in contract documents and their effects on construction projects. Questionnaire survey and 51 case study projects (mixed method were adopted for the study. The study also involved the use of Delphi technique to extract the possible errors that may be contained in contract documents; it did not however constitute the empirical data for the study. The sample of the study consists of 985 consulting and 275 contracting firms that engaged in the construction of building projects that were completed between 2013 and 2016 and were above the ground floor. The two-stage stratified random sampling technique was adopted for the study. The data for the study were analysed with descriptive and inferential statistics (based on Shapiro-Wilk’s test. The results of the study indicate that errors in contract documents were moderately prevalent. However, overmeasurement in bill of quantities was prevalent in private, institutional and management procured projects. Traditionally procured projects contain 68% of the errors in contract documents among the procurement methods. Drawings contain the highest number of errors, followed by bill of quantities and specifications. The severe effects of errors in contract documents were structural collapse, deterioration of buildings and contractors’ claims among others. The result of the study implies that, management procurement method is the route to error minimization in developing countries, but it may need to be backed by law and guarded against overmeasurement.

  4. Performance contracting to engage detoxification-only patients into continued rehabilitation.

    Science.gov (United States)

    Haley, Sean J; Dugosh, Karen Leggett; Lynch, Kevin G

    2011-03-01

    In 2006, only 18.7% of Delaware's detoxification patients were admitted to continuing recovery-oriented treatment within 30 days after discharge. In response, Delaware established financial contingencies to (1) maintain 90% detoxification occupancy, (2) make receipt of 10% of the facility's monthly reimbursement contingent on 25% of patients entering treatment, and (3) provide a $500 bonus for every patient with three or more prior detoxification visits who was retained in treatment. Under the performance contract, the detoxification provider (1) maintained the 90% occupancy requirement, (2) achieved the 25% treatment entry target for 7 of 12 months, and (3) observed only 8% (27/337) of detoxification completions that met the targeted length of stay. Continuation to and retention in treatment was even more constrained for patients with three or more prior detoxifications. Contrary to the policy intent, the number of patients with three or more detoxifications in fiscal year (FY) 2008 is nearly triple that of FY 2006. The modest gain in the transition rate was achieved without changes in patient access; the FY 2008 patient population reported significantly higher rates of homelessness and a younger age of first use than before the performance contract in FY 2006. Performance contracting may offer promise for improving transition to treatment rates. However, the unique needs of detoxification patients, the treatment capacity of each level of care to meet patient needs, and the structure of the performance contract must be carefully considered. Performance contracting efforts may be strengthened when service contracts across the system are tightly synchronized. Copyright © 2011 Elsevier Inc. All rights reserved.

    Physical exercise has potent therapeutic and preventive effects against metabolic disorders. A number of studies have suggested that 5'-AMP-activated protein kinase (AMPK) plays a pivotal role in regulating carbohydrate and lipid metabolism in contracting skeletal muscles, while several genetically manipulated animal models revealed the significance of AMPK-independent pathways. To elucidate significance of AMPK and AMPK-independent signals in contracting skeletal muscles, we conducted a metabolomic analysis that compared the metabolic effects of 5-aminoimidazole-4-carboxamide-1-β-D-ribonucleoside (AICAR) stimulation with the electrical contraction ex vivo in isolated rat epitrochlearis muscles, in which both α1- and α2-isoforms of AMPK and glucose uptake were equally activated. The metabolomic analysis using capillary electrophoresis time-of-flight mass spectrometry detected 184 peaks and successfully annotated 132 small molecules. AICAR stimulation exhibited high similarity to the electrical contraction in overall metabolites. Principal component analysis (PCA) demonstrated that the major principal component characterized common effects whereas the minor principal component distinguished the difference. PCA and a factor analysis suggested a substantial change in redox status as a result of AMPK activation. We also found a decrease in reduced glutathione levels in both AICAR-stimulated and contracting muscles. The muscle contraction-evoked influences related to the metabolism of amino acids, in particular, aspartate, alanine, or lysine, are supposed to be independent of AMPK activation. Our results substantiate the significance of AMPK activation in contracting skeletal muscles and provide novel evidence that AICAR stimulation closely mimics the metabolomic changes in the contracting skeletal muscles.

    Resistance training with eccentric contraction has been shown to augment muscle hypertrophy more than other contraction modes do (i.e., concentric and isometric contraction). However, the molecular mechanisms involved remain unclear. The purpose of this study was to investigate the effect of muscle contraction mode on mammalian target of rapamycin complex 1 (mTORC1) signaling using a standardized force-time integral (load (weight) × contraction time). Male Sprague-Dawley rats were randomly assigned to three groups: eccentric contraction, concentric contraction, and isometric contraction. The right gastrocnemius muscle was exercised via percutaneous electrical stimulation-induced maximal contraction. In experiment 1, different modes of muscle contraction were exerted using the same number of reps in all groups, while in experiment 2, muscle contractions were exerted using a standardized force-time integral. Muscle samples were obtained immediately and 3 h after exercise. Phosphorylation of molecules associated with mTORC1 activity was assessed using western blot analysis. In experiment 1, the force-time integral was significantly different among contraction modes with a higher force-time integral for eccentric contraction compared to that for other contraction modes (P contraction compared to that for isometric contraction (P contraction than for other modes of contraction (P contraction was higher than isometric contraction (P contraction modes 3 h after exercise. Our results suggest that mTORC1 activity is not determined by differences in muscle contraction mode itself. Instead, mTORC1 activity is determined by differences in the force-time integral during muscle contraction. © 2016 The Authors.

    The five contracts for Temporary Labour assignments on the CERN site (L020/PE, L021/PE, L022/PE, L023/PE and L024/PE) approved by the Finance Committee in March 1996 (CERN/FC/3857) will reach the end of their initial three-year contractual period at the end of December 1999. Following the satisfactory execution of these contracts during this period, CERN requests approval to extend them from January 2000 for the first of the two years foreseen in the original adjudication. The Finance Committee is invited: - to take note that the three-year expenditure for Temporary Labour contracts from 1997 to 1999 will not exceed 19 100 000 Swiss francs, compared to the 18 900 000 Swiss francs estimated at the time of the adjudication in March 1996; - to approve an extension of the present Temporary Labour contracts for the year 2000 for a total amount not exceeding 6 000 000 Swiss francs.

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

    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.

    To supplement in-house investigations, Agriculture Canada contracted out research in a number of programs including three which supported engineering work. This document lists the contracts awarded under the programs and provides reference citations of the contract reports. Reports are grouped by file number, scientific authority, author or contractor, and subject, and a subject index is also included. The three programs are: Development, Research and Evaluation in Agricultural Mechanization (DREAM), Agricultural Engineering Research and Development Program (AERD), and Energy Research and Development in Agriculture and Food (ERDAF). AERD, which replaced DREAM, has been terminated, but the ERDAF program is still continuing as of the date of this document.

  12. JURIDICAL WILL IN CONTRACTS

    Directory of Open Access Journals (Sweden)

    Emilian CIONGARU

    2015-07-01

    Full Text Available In the business law, almost all judicial relationships of private law are obligational juridical relationships which are made up of legal acts and facts. The most important legal act is the contract since it is the basis of the social life in any community meaning that it represents the most important economic and juridical instrument for the participants to a contract. The persons are free and equal in society and, consequently, no power is valid and fundamental unless it relies on their consent, namely on a contract. So, the existence of a civil contract relies on the principles of consensualism, a perception based on moral rules to observe one’s promises, to have good faith and to observe the interests of your fellow creature. The exterior manifestation, the expression or declaration of the juridical will constitutes the consent of such person in making the structure of contract. The declared will must correspond to the person’s real will and the adoption and declaration of the juridical will must take place consciously. Any contract that does not derive from juridical will is null and the civilizing character is inexistent. The principles giving sense to consensualism is the one of agreement between parties so as to produce legal effects by itself and it is enough for the conclusion of a contract, regardless of the form in which it is exteriorized, a principle expressed by the Latin adagio pacta sunt servanda.

  13. Test-retest reliability of the different dynamometric variables used to evaluate pelvic floor musculature during the menstrual cycle.

    The aim of this study was to evaluate the reliability of different dynamometric variables of the pelvic floor muscles (PFM) in healthy women during different periods of menstrual cycle. Vaginal dynamometric equipment was developed by the authors and its reproducibility was tested. The PFM contractions of 20 healthy women were collected by two independent examiners over three consecutive weeks, always on the same day, with a seven-day interval between readings, starting from the first day after the end of the menstrual period. For the measurements, the branch of the dynamometer was positioned first on the sagittal plane and then on the frontal plane. Baseline, peak time, maximum PFM strength, impulse contraction, and average contraction force were calculated. Reproducibility was tested using the intra-class correlation coefficient (ICC) and standard error of measurement. Repeated-measures ANOVA was used to compare the data from different days. For intra-day and inter-day reliability between examiners, all the parameters collected on the sagittal plane presented good and excellent reproducibility (ICC 2,1  = 0.60 to 0.98), whereas reproducibility on the frontal plane was respectively poor and excellent (ICC 2,1  = 0.23 to 0.97). The ANOVA revealed significant differences between sessions only for the impulse of contraction for the sagittal (P = 0.005) and frontal (P = 0.03) planes. Time and contraction force parameters of the PFM are not influenced by hormonal alterations that occur during the menstrual cycle. The impulse of contraction was the only variable to demonstrate a significant difference between the first and second week of the data collection protocol. The baseline, maximum strength value, impulse of contraction, and average contraction force variables presented good to excellent reproducibility and can be safely used as a method of PFM evaluation. © 2018 Wiley Periodicals, Inc.

  14. Hydroxyl layer: trend of number density and intra-annual variability

    The layer of vibrationally excited hydroxyl (OH*) near the mesopause in Earth's atmosphere is widely used to derive the temperature at this height and to observe dynamical processes such as gravity waves. The concentration of OH* is controlled by the product of atomic hydrogen, with ozone creating a layer of enhanced concentration in the mesopause region. However, the basic influences on the OH* layer are atomic oxygen and temperature. The long-term monitoring of this layer provides information on a changing atmosphere. It is important to know which proportion of a trend results from anthropogenic impacts on the atmosphere and which proportion reflects natural variations. In a previous paper (Grygalashvyly et al., 2014), the trend of the height of the layer and the trend in temperature were investigated particularly in midlatitudes on the basis of our coupled dynamic and chemical transport model LIMA (Leibniz Institute Middle Atmosphere). In this paper we consider the trend for the number density between the years 1961 and 2009 and analyze the reason of the trends on a global scale. Further, we consider intra-annual variations. Temperature and wind have the strongest impacts on the trend. Surprisingly, the increase in greenhouse gases (GHGs) has no clear influence on the chemistry of OH*. The main reason for this lies in the fact that, in the production term of OH*, if atomic hydrogen increases due to increasing humidity of the middle atmosphere by methane oxidation, ozone decreases. The maximum of the OH* layer is found in the mesopause region and is very variable. The mesopause region is a very intricate domain marked by changeable dynamics and strong gradients of all chemically active minor constituents determining the OH* chemistry. The OH* concentration responds, in part, very sensitively to small changes in these parameters. The cause for this behavior is given by nonlinear reactions of the photochemical system being a nonlinear enforced chemical oscillator

    2009-08-01

    We check the impact of the factorization scheme employed in the calculation of the heavy-quark deep-inelastic scattering (DIS) electro-production on the PDFs determined in the NNLO QCD analysis of the world inclusive neutral-current DIS data combined with the ones on the neutrino-nucleon DIS di-muon production and the fixed-target Drell-Yan process. The charm-quark DIS contribution is calculated in the general-mass variable-flavor-number (GMVFN) scheme: At asymptotically large values of the momentum transfer Q it is given by the zero-mass 4-flavor scheme and at the value of Q equal to the charm-quark mass it is smoothly matched with the 3-flavor scheme using the Buza-Matiounine-Smith-van Neerven prescription. The PDFs obtained in this variant of the fit are very similar to the ones obtained in the fit with a 3-flavor scheme employed. Our 5-flavor PDFs derived from the 3-flavor ones using the NNLO matching conditions are used to calculate the rates of W ± /Z and t anti t production at the Tevatron collider and the LHC at NNLO.

  4. Precarious Pedagogies? The Impact of Casual and Zero-Hour Contracts in Higher Education

    Directory of Open Access Journals (Sweden)

    Ana Lopes

    2015-05-01

    Full Text Available Precarious work is associated with and characterizes the effects of neoliberal policy—the transference of economic risk onto workers, the erosion of workers’ rights, the flexibilization and casualization of work contracts, self-responsibility, financial insecurity, and emotional stress. In the Higher Education (HE sector, the number of insecure academic jobs, especially zero-hour contracts for hourly paid teaching and short-term contract research, has grown exponentially in recent years in response to the structural and fiscal changes within universities, which reflect these global shifts. This paper presents findings from a pilot study conducted with academics on casual contracts in HE institutions in England and Wales. Qualitative interviews and focus groups were undertaken with teachers (lecturers and tutors on hourly paid and zero-hour contracts to examine the relationship between their contractual situations and pedagogical practices. The research broadly seeks to contribute to ongoing discussions concerned with the impact of neoliberalism on higher education and specifically highlights the case of contingent lecturers as casualties of the casualization of the academic labor force.

    The contract is the last and final step of project planning and the first step of project implementation. The contract has to specify in detail and to the point, as concisely as possible, the complete scope of supplies and work, define all technical particulars and requirements, put forward the conditions of legal, regulatory, administrative and financial procedure, prepare for operating and maintenance instructions to be issued after commissioning. In short, the contract is expected to be a reliable instrument during the manufacturing and construction period as well as a guide-book to assist the owner afterwards in the operation and maintenance of the plant.

  12. Leader--member exchange, differentiation, and psychological contract fulfillment: a multilevel examination.

    Science.gov (United States)

    Henderson, David J; Wayne, Sandy J; Shore, Lynn M; Bommer, William H; Tetrick, Lois E

    2008-11-01

    Prior integrations of the leader-member exchange (LMX) and psychological contract literatures have not clarified how within-group LMX differentiation influences employees' attitudes and behaviors in the employment relationship. Therefore, using a sample of 278 members and managers of 31 intact work groups at 4 manufacturing plants, the authors examined how LMX operating at the within-group level (relative LMX, or RLMX) and the group level influenced perceptions of psychological contract fulfillment and employee-level outcomes. Controlling for individual-level perceptions of LMX quality, results indicated a positive relationship between RLMX and fulfillment, which was strengthened as group-level variability in LMX quality increased. Perceptions of fulfillment mediated the relationship between RLMX and performance and sportsmanship behaviors. The importance of conceptualizing LMX as simultaneously operating at multiple levels is highlighted.

  13. 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.

  14. A trace-based model for multiparty contracts

    DEFF Research Database (Denmark)

    Hvitved, Tom; Klaedtke, Felix; Zălinescu, Eugen

    2012-01-01

    In this article we present a model for multiparty contracts in which contract conformance is defned abstractly as a property on traces. A key feature of our model is blame assignment, which means that for a given contract, every breach is attributed to a set of parties. We show that blame...... assignment is compositional by de¿ning contract conjunction and contract disjunction. Moreover, to specify real-world contracts, we introduce the contract speci¿cation language CSL with an operational semantics. We show that each CSL contract has a counterpart in our trace-based model and from...... the operational semantics we derive a run-time monitor. CSL overcomes limitations of previously proposed formalisms for specifying contracts by supporting: (history sensitive and conditional) commitments, parametrised contract templates, relative and absolute temporal constraints, potentially in¿nite contracts...

    1977-01-01

    To make energy available economically and in sufficient quantity is a main point for the future of an industrial and more for a developing country. The investment costs and the availability of a power plant and in particular for a nuclear power plant are the most significant factors in the economic operation of the plant. In the phase before signing the contract the essential decisions are made with high influence in the economic operation and the availability of the plant. A turn-key contract offers good possibilities to minimize the risks referring a) the plant quality and functionality, b) the plant investment cost, c) the plant completion date, d) the handling of the licensing procedures, e) the availability of the operation. The lecture mentions the points which are of high influence for a successful erection and operation period and which must be clarified before signing the contract between the buyer and supplier of the plant.

  15. Manual of contracts for the electricity sector. Contracts that work: Drafting and proper legal application. 2. rev. ed.

    International Nuclear Information System (INIS)

    Schoene, Thomas

    2014-01-01

    This manual deals fundamentally with the drafting of contracts for the electricity sector. It covers all types of contracts on both the customer and the network side with their various special clauses and variants, specifically: basic supply, substitute supply, supply contracts for private, commercial and industrial special customers as well as redistributors, EFET contracts, network access contracts, supplier framework contracts, feed-in contracts, grid connection contracts and connection use contracts. The manual also addresses questions concerning electricity customer insolvency, an issue of growing importance. The following topics are furthermore dealt with in a practically oriented manner and with care being taken to explain the underlying legal issues in readily understandable language. What basic framework conditions are specified by the new energy economy laws and general civil law? What possibilities are available in drafting contracts and what are the ramifications in each case? What subject matters in a contract are of particular economic significance? How can concession contracts be designed in a market-conforming way when there is strong competition for qualified rights of way? What opportunities and risks are associated with innovative products? What options for action does a supplier have in the event of (threatening) customer insolvency? Model contracts from day-to-day management practice and tips, checklists and cautioning notes round off this manual.

  16. Dynamics of chromosome number and genome size variation in a cytogenetically variable sedge (Carex scoparia var. scoparia, Cyperaceae).

    Science.gov (United States)

    Chung, Kyong-Sook; Weber, Jaime A; Hipp, Andrew L

    2011-01-01

    High intraspecific cytogenetic variation in the sedge genus Carex (Cyperaceae) is hypothesized to be due to the "diffuse" or non-localized centromeres, which facilitate chromosome fission and fusion. If chromosome number changes are dominated by fission and fusion, then chromosome evolution will result primarily in changes in the potential for recombination among populations. Chromosome duplications, on the other hand, entail consequent opportunities for divergent evolution of paralogs. In this study, we evaluate whether genome size and chromosome number covary within species. We used flow cytometry to estimate genome sizes in Carex scoparia var. scoparia, sampling 99 plants (23 populations) in the Chicago region, and we used meiotic chromosome observations to document chromosome numbers and chromosome pairing relations. Chromosome numbers range from 2n = 62 to 2n = 68, and nuclear DNA 1C content from 0.342 to 0.361 pg DNA. Regressions of DNA content on chromosome number are nonsignificant for data analyzed by individual or population, and a regression model that excludes slope is favored over a model in which chromosome number predicts genome size. Chromosome rearrangements within cytogenetically variable Carex species are more likely a consequence of fission and fusion than of duplication and deletion. Moreover, neither genome size nor chromosome number is spatially autocorrelated, which suggests the potential for rapid chromosome evolution by fission and fusion at a relatively fine geographic scale (<350 km). These findings have important implications for ecological restoration and speciation within the largest angiosperm genus of the temperate zone.

    1975-01-01

    A non-turnkey contract differs from a turnkey contract in no special formal way. The way the buyer chooses to exercise his project leadership must be concretized in the contract. The way and extent he wishes to exercise technical checking must be laid down in the form of clear rules. The way information has to flow from one contractor over buyer to others and vice versa has to be laid down in detail and the consequences of non conformance fixed in such a manner that optimum project performance is reached.

  2. Esophageal striated muscle contractions in patients with Chagas' disease and idiopathic achalasia

    Directory of Open Access Journals (Sweden)

    R.O. Dantas

    2002-06-01

    Full Text Available Chagas' disease causes degeneration and reduction of the number of intrinsic neurons of the esophageal myenteric plexus, with consequent absent or partial lower esophageal sphincter relaxation and loss of peristalsis in the esophageal body. The impairment of esophageal motility is seen mainly in the distal smooth muscle region. There is no study about esophageal striated muscle contractions in the disease. In 81 patients with heartburn (44 with esophagitis taken as controls, 51 patients with Chagas' disease (21 with esophageal dilatation and 18 patients with idiopathic achalasia (11 with esophageal dilatation we studied the amplitude, duration and area under the curve of esophageal proximal contractions. Using the manometric method and a continuous perfusion system we measured the esophageal striated muscle contractions 2 to 3 cm below the upper esophageal sphincter after swallows of a 5-ml bolus of water. There was no significant difference in striated muscle contractions between patients with heartburn and esophagitis and patients with heartburn without esophagitis. There was also no significant difference between patients with heartburn younger or older than 50 years or between men and women or in esophageal striated muscle contractions between patients with heartburn and Chagas' disease. The esophageal proximal amplitude of contractions was lower in patients with idiopathic achalasia than in patients with heartburn. In patients with Chagas' disease there was no significant difference between patients with esophageal dilatation and patients with normal esophageal diameter. Esophageal striated muscle contractions in patients with Chagas' disease have the same amplitude and duration as seen in patients with heartburn. Patients with idiopathic achalasia have a lower amplitude of contraction than patients with heartburn.

    DEFF Research Database (Denmark)

    Ploug, Thorkil; Galbo, Henrik; Richter, Erik

    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...

    2018-01-12

    Integrated care systems as well as accountable care organisations (ACOs) in the US and similar concepts in other countries are advocated as an effective method of improving the performance of healthcare systems. These systems outline a payment and care delivery model that intends to tie provider reimbursements to predefined quality metrics. By this the total costs of care shall be reduced. When designing healthcare options contractors are faced with a variety of financial options. The costs of market utilisation are highly relevant for the conception of healthcare contracts; furthermore contract-specific investments are an obstacle to the efficient operation of ACOs. A comprehensive literature review on methods of designing contracts in Integrated Care was conducted. This article is the second in a row of three that are all published in this issue and contribute to a specific issue in designing healthcare contracts. The first dealt with the organisation of contracts and information asymmetries, while part 3 concludes with the question of risk management and evaluation. The specific research question of this second article focusses on the financial options and reimbursement schemes that are available to define healthcare contracts. A healthcare contract is a relational contract, which determines the level of reimbursement, the scope of services and the quality between service providers and payers, taking account of the risks relating to population and performance. A relational contract is an agreement based upon assumption of a longer timeframe. A major obstacle to the practical implementation of healthcare contracts is the prognosis of the inflows and outflows due to the actuarial risks of the insured population. Financing conditions and reimbursement arrangements that are based on a prospectively determined fixed price, have a significant drawback: it is very difficult to take the differences in health status and the utilisation of distinct insured clientele

  16. Evidence for range contraction of snowshoe hare in Pennsylvania

    Science.gov (United States)

    Diefenbach, Duane R.; Rathbun, Stephen L.; Vreeland, J.K.; Grove, Deborah; Kanapaux, William J.

    2016-01-01

    In Pennsylvania, Lepus americanus (Snowshoe Hare) is near the southern limits of its range and at risk of range contraction because of loss of early-successional forest and impacts of climate change. We used hunter-harvest data to investigate changes in the distribution of Snowshoe Hare in Pennsylvania (1983–2011), forest inventory and land-use data to assess changes in amount and distribution of early-successional forest (1988–2011), and occupancy modeling (2004) to identify habitat and climate variables that explain the current distribution of Snowshoe Hare. We determined presence of Snowshoe Hare based on visual sightings, observations of tracks, and DNA analysis of fecal pellets, and used repeated visits to sampling sites and occupancy models to estimate occupancy rates (Ψ). Hunter-harvest data indicated the range of Snowshoe Hare in Pennsylvania contracted towards northwestern and northeastern portions of the state. Based on occupancy modeling, Snowshoe Hare were most likely to occupy early-successional and mixed deciduous-coniferous forest types and areas with colder winter temperatures, which coincided with the distribution of hunter harvests. Among the 4 forest types, we estimated Ψ = 0.52-0.79 and Ψ = 0.10-0.32 where winter temperatures were coldest and warmest, respectively. Total forest loss was Pennsylvania may decline from 0.27 in 2004 to 0.10–0.18 by 2050–2059, depending on the climate model. The range of Snowshoe Hare in Pennsylvania has contracted to regions of Pennsylvania with the coldest winter temperatures and most persistent snowpack, and based on projected climate change, our results suggest further range contraction of Snowshoe Hare in Pennsylvania.

  6. Management of transport and handling contracts

    CERN Document Server

    Rühl, I

    2004-01-01

    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.

    Full Text Available In this work not only legal nature of catering services is analyzed, but also legal position of parties in it. Catering contract (Housing and Bed and Board Contract is unnamed in our country and the main source of law for this contract are business practices and usage. A lot of attention is paid to this question. Lack of legal norms for this area is general characteristic for most of the tourism contracts. In this contract its title is also debatable because term 'catering services' is not usually used in practice. Although this contract is unnamed in Comparative Law ,in tourist more developed countries there are more codified business practices from this area and there is more Case Law. Having in mind development of tourist economy adequate legal conditions in tourism contract are expected.

  8. IAEA research contracts. Second annual report

    International Nuclear Information System (INIS)

    1962-01-01

    During the period in which the Agency's research programme has been operative, nearly 150 research contracts have been placed with institutions in 35 Member States. While considerable emphasis was placed initially on research of a more fundamental nature - as reflected by the summaries presented herein of work under contracts awarded in the early stages of the programme - recent policy has shifted the major emphasis toward research of a practical nature, as the results of this type of research are likely to be of more immediate interest to Member States, and particularly to the developing nations. In every case, the summary of the contractor's final report has been prepared by that member of the Agency's scientific staff who has been closely connected with that particular subject of research. Thus, the scientific data reported in the summary remain the responsibility of the contractor, the Agency being responsible for any additional observations. The reports of the following contracts are included: Research Contract No. 1, Factors controlling the distribution of fission products in the biosphere; Research Contract No. 4, The development of a method of non-destructive analysis to determine the U-235 and Pu content of irradiated fuel elements that are in storage under water and that have been out of the reactor for periods of more than one month; Research Contract No. 5, Non-destructive method for evaluating the U-235 and Pu content of irradiated fuel elements; Research Contract No. 19, Studies of contamination in local marine resources, and more specifically the determination of horizontal and vertical diffusion rates in Suruga Bay; Research Contract No. 22, A study of the uptake, accumulation and loss of radioactive material by marine bacteria; Research Contract No. 26, (a) Red cell life span in patients with congenital or acquired haemolytic anaemia using Cr-51 and pie-operative spleen scanning; (b) The aeriology of tropical iron deficiency anaemia using Fe-59 in

    Full Text Available Contractualization is kind of goverment activity in acquiring goods, services and infrastructure as well. Procurement contract has several important function especially in enhancing economic development in a state. In Indonesia, this kind of contract also has function in empowering micro economic scale. Since the aim of procurement study is to provide equal protection between public fund interest in one hand and privat sector in the other hand, general principle of contract law must be taken into consideration together with transparency as the most important principle in government contract.

  15. Food and drink serving contract

    Directory of Open Access Journals (Sweden)

    Veselinović Janko

    2012-01-01

    Full Text Available Food and drink catering service is almost as old as the civilization itself. Even though this vocation is a part of the catering activity, Serbian law does not foresee this contract section as personalized. Key legal sources for this kind of contract are business customs. Food and drink serving contract is a mixed-type contract and its legal nature is very interesting due to its complexity. Specific for this contract is the fact that it is not an ordinary service, but also an activity which requires a degree of culinary skills, knowledge of customs of other nations, as well as other skills. The very category of a good professional in business economy / hospitality industry is very dynamic, as it needs to be evaluated according to all given circumstances, which may be rather unpredictable. By considering the legal nature, but also the rights and obligations of the contracting parties, we tried to point to the questions that require a special attention. Legal sources that indirectly refer to food and drink serving contracts were taken into account. Apart from the Law on Obligatory Relations, we also considered here the Law on Tourism also pointing to the comparative law and jurisprudence.

  18. Estimating Composite Curve Number Using an Improved SCS-CN Method with Remotely Sensed Variables in Guangzhou, China

    Directory of Open Access Journals (Sweden)

    Qihao Weng

    2013-03-01

    Full Text Available The rainfall and runoff relationship becomes an intriguing issue as urbanization continues to evolve worldwide. In this paper, we developed a simulation model based on the soil conservation service curve number (SCS-CN method to analyze the rainfall-runoff relationship in Guangzhou, a rapid growing metropolitan area in southern China. The SCS-CN method was initially developed by the Natural Resources Conservation Service (NRCS of the United States Department of Agriculture (USDA, and is one of the most enduring methods for estimating direct runoff volume in ungauged catchments. In this model, the curve number (CN is a key variable which is usually obtained by the look-up table of TR-55. Due to the limitations of TR-55 in characterizing complex urban environments and in classifying land use/cover types, the SCS-CN model cannot provide more detailed runoff information. Thus, this paper develops a method to calculate CN by using remote sensing variables, including vegetation, impervious surface, and soil (V-I-S. The specific objectives of this paper are: (1 To extract the V-I-S fraction images using Linear Spectral Mixture Analysis; (2 To obtain composite CN by incorporating vegetation types, soil types, and V-I-S fraction images; and (3 To simulate direct runoff under the scenarios with precipitation of 57mm (occurred once every five years by average and 81mm (occurred once every ten years. Our experiment shows that the proposed method is easy to use and can derive composite CN effectively.

  20. Long-term contract auctions and market power in regulated power industries

    International Nuclear Information System (INIS)

    Soledad Arellano, M.; Serra, Pablo

    2010-01-01

    A number of countries with oligopolistic power industries have used marginal cost pricing to set the price of energy for small customers. This course of action, however, does not necessarily ensure an efficient outcome when competition is imperfect. The purpose of this paper is to study how the auction of long-term contracts could reduce market power. We do so in a two-firm, two-technology, linear-cost, static model where demand is summarized by a price inelastic load curve. In this context we show that the larger the proportion of total demand auctioned in advance, the lower are both the contract and the average spot price of energy.

  2. On the Dogmatics of Contract Interpretation

    Institute of Scientific and Technical Information of China (English)

    Yang Guoqing

    2017-01-01

    The interpretation of contract has attracted much attention in the practice of contract law and the basic problems to be solved are what the parties agree on and how to set up the rules of adjudication. The present domestic studies are not conducive to contract prac-tices because they either unnecessarily elevate scientific problems to the speculative realm of fantasy, or make the problems become more unreal and abstract. The two traditional theories of contract interpretation do not conflict in values in terms of the autonomy of the will and trust protection. However, in today' s society where cultural pluralism and legal value plural-ism exist, because of different contract practices, differentiation and individualization of con-tract interpretation will become the basic patterns. Therefore, it is impossible and unnecessary to construct a unitary model, but it is of great significance to introduce the dogmatics-orien-ted contract interpretation.

  11. Contractions of 2D 2nd Order Quantum Superintegrable Systems and the Askey Scheme for Hypergeometric Orthogonal Polynomials

    Directory of Open Access Journals (Sweden)

    Ernest G. Kalnins

    2013-10-01

    Full Text Available We show explicitly that all 2nd order superintegrable systems in 2 dimensions are limiting cases of a single system: the generic 3-parameter potential on the 2-sphere, S9 in our listing. We extend the Wigner-Inönü method of Lie algebra contractions to contractions of quadratic algebras and show that all of the quadratic symmetry algebras of these systems are contractions of that of S9. Amazingly, all of the relevant contractions of these superintegrable systems on flat space and the sphere are uniquely induced by the well known Lie algebra contractions of e(2 and so(3. By contracting function space realizations of irreducible representations of the S9 algebra (which give the structure equations for Racah/Wilson polynomials to the other superintegrable systems, and using Wigner's idea of ''saving'' a representation, we obtain the full Askey scheme of hypergeometric orthogonal polynomials. This relationship directly ties the polynomials and their structure equations to physical phenomena. It is more general because it applies to all special functions that arise from these systems via separation of variables, not just those of hypergeometric type, and it extends to higher dimensions.

  12. IDENTIFICATION OF THOSE VARIABLES THAT HAVE A SIGNIFICANT INFLUENCE ON THE EXPECTED NUMBER OF DAYS OF STAYING IN THE CENTRE DEVELOPMENT REGION OF ROMANIA

    Directory of Open Access Journals (Sweden)

    Erika KULCSÁR

    2010-06-01

    Full Text Available I started from the assumption that there are more variables that have a significant influence on the expected number of days of staying in the Centre Development Region. To identify those variables this paper includes the analysis of variance with two variables that are not interacting, in this case the dependent variable is the question "How many days did you plan to stay in Centre Development Region?" and the independent variables are: "What is the purpose of your stay?" "What is the highest level of education?". Given that there are cases when interactions occur between variables, I also analyzed the interaction effects between the two independent variables. The paper also includes an ANOVA analysis with three variables between which interactions relationships occur. After identifying the dependency relations between the variables I found that the inclusion of the third variable, namely the "Marital status" of respondents, adds value to the model. Following the results obtained by ANOVA analysis, I identified those socio-demographic characteristics that, in my opinion, companies that operate on tourist market in the Center Development Region should consider when fundamenting marketing strategies in tourism.

  13. 3D power Doppler ultrasound assessment of placental perfusion during uterine contraction in labor.

    Sato, Miki; Noguchi, Junko; Mashima, Masato; Tanaka, Hirokazu; Hata, Toshiyuki

    2016-09-01

    To assess placental perfusion during spontaneous or induced uterine contraction in labor at term using placental vascular sonobiopsy (PVS) by 3D power Doppler ultrasound with the VOCAL imaging analysis program. PVS was performed in 50 normal pregnancies (32 in spontaneous labor group [SLG], and 18 in induced labor group with oxytocin or prostaglandin F2α [ILG]) at 37-41 weeks of gestation to assess placental perfusion during uterine contraction in labor. Only pregnancies with an entirely visualized anterior placenta were included in the study. Data acquisition was performed before, during (at the peak of contraction), and after uterine contraction. 3D power Doppler indices such as the vascularization index (VI), flow index (FI), and vascularization flow index (VFI) were calculated in each placenta. There were no abnormal fetal heart rate tracings during contraction in either group. VI and VFI values were significantly reduced during uterine contraction in both groups (SLG, -33.4% [-97.0-15.2%], and ILG, -49.6% [-78.2--4.0%]), respectively (P power Doppler indices (VI, FI, and VFI) during uterine contraction (at the peak of contraction) showed a correlation greater than 0.7, with good intra- and inter-observer agreements. Our findings suggest that uterine contraction in both spontaneous and induced labors causes a significant reduction in placental perfusion. Reduced placental blood flow in induced uterine contraction has a tendency to be marked compared with that in spontaneous uterine contraction. To the best of our knowledge, this is the first study on the non-invasive assessment of placental perfusion during uterine contraction in labor using 3D power Doppler ultrasound. However, the data and their interpretation in the present study should be taken with some degree of caution because of the small number of subjects studied. Further studies involving a larger sample size are needed to assess placental perfusion and vascularity using PVS during normal and

  14. A global perspective on foreign contract labor.

    Science.gov (United States)

    Smart, J E; Casco, R R

    1988-01-01

    This paper provides a general overview on foreign contract labor. The growth in the use of foreign contract labor is described with reference to other types of international labor movements such as 1) illegal, undocumented, or irregular migration; 2) free migration; and 3) permanent settlement migration. Within this general context, the various national advantages and disadvantages of contract labor are outlined. Particular issues like the role of trade unions and the likely future international labor circulation are noted. The 1984 World Labour Report estimates a global stock of almost 22 million foreign workers. Despite lack of reliable data, the size of irregular labor flows is considerable. More than 4 million undocumented workers, primarily Mexicans, can be found in the US alone. Other major flows of illegal labor go from China to Hong Kong, Malaysia to Singapore, Columbia to Venezuela, and poor Arab countries to oil-exporting countries in the Middle East. Laws are often poorly enforced and contradictory. Employers often actively recruit illegal migrants. While permanent migration was formerly the primary source of foreign workers, the numbers migrating in this manner are decreasing significantly. In absolute terms, host countries gain considerably more through the use of contract labor than sending countries. The pervasive commitment of national governments to economic growth is a prime consideration in the decision to import foreign labor. In general, trade unions have created an environment wherein the use of foreign labor in the formal as opposed to the informal labor market is more difficult. The disadvantages of labor export include the costs of family separation, worker exploitation, and cultural alienation. Remittances constitute the most tangible return of labor export. In many countries they have made a very considerable impact on the balance of payments deficit.

    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.

    Spending on clinical contracts continues to outpace spending on business services, but may be leveling off. The 12th annual Contract Management Survey shows that the performance of clinical vendors is now comparable to business service vendors in meeting savings targets. Both business and clinical vendors are receiving higher marks from hospital leaders, but execs quickly respond to low marks by bringing the service back in-house of changing vendors. This report examines trends in outsourcing, satisfaction levels, the decision-making process, contract features and performance, and spending.

    1996-10-01

    Fluorescent in situ hybridization (FISH) was applied to related Populus species (2n = 19) in order to detect rDNA loci. An interspecific variability in the number of hybridization sites was revealed using as probe an homologous 25S clone from Populus deltoides. The application of image analysis methods to measure fluorescence intensity of the hybridization signals has enabled us to characterize major and minor loci in the 18S-5.8S-25S rDNA. We identified one pair of such rDNA clusters in Populus alba; two pairs, one major and one minor, in both Populus nigra and P. deltoides; and three pairs in Populus balsamifera, (two major and one minor) and Populus euroamericana (one major and two minor). FISH results are in agreement with those based on RFLP analysis. The pBG13 probe containing 5S sequence from flax detected two separate clusters corresponding to the two size classes of units that coexist within 5S rDNA of most Populus species. Key words : Populus spp., fluorescent in situ hybridization, FISH, rDNA variability, image analysis.

  19. Contract design

    International Nuclear Information System (INIS)

    Bradley, P.

    2006-01-01

    The current state of the electric power industry in Ontario was discussed with particular reference to the procurement of contracts and why the Ontario Power Authority (OPA) must be contracting to resolve many of Ontario's electricity issues. As Ontario increasingly relies on imports and natural gas-fired generation, the price of electricity continues to rise given that supply is at a low level. In addition to the generation gap, there are also several transmission constrained areas in Ontario, particularly in the Greater Toronto Area (GTA). The OPA announced 2 projects totalling 1900 MW to relieve congestion. According to the Independent Electricity System Operator (IESO), the total potential opportunity for new generation by 2015 is about 5,000 to 7,000 megawatts. OPA is expected to launch procurement processes for up to 1000 MW of cogeneration, 250 MW of province-wide conservation initiatives, 1900 MW of generation in the western part of the GTA, and 600 MW of generation in downtown Toronto. New nuclear capacity is also anticipated in addition to renewables and conservation/demand management (CDM) initiatives. The OPA's competitive procurement processes will include requests for expressions of interest, requests for qualifications and requests for proposals. The challenge of balancing the technical complexities and realities of procuring generation assets with the need for a fair procurement process was discussed. Contracts will be designed to react to market signals and will include 3 styles: tariff style, tolling style and standard offer contract.

    Directory of Open Access Journals (Sweden)

    2007-07-01

    Full Text Available In a face-to-face classroom, the instructor can easily diagnose students’ motivational status by observing their facial expressions and postures, but such cues are absent in an online classroom. Therefore, online instructors often estimate students’ motivational level based on their online behavior such as the number of messages they post, and look for effective strategies to help them actively participate in online dialogues. One such strategy is contract learning which facilitates self-directed behaviors through structuring an agreed learning process. This study reports a contract learning strategy in a graduate-level online class, examining whether a sample of 28 students’ motivation could indeed be predicted by their online behavior. Results from the study found that the students’ online behavior was not a predictor for their motivational status, though there were age and gender differences in their online behavior. The students felt more self-directed and motivated during contract learning, but what they really liked was being able to select assignments that were relevant to their interests and needs. This paper concludes by discussing practical implications of the findings at the end.

  1. Optimal defense with variable number of overarching and individual protections

    International Nuclear Information System (INIS)

    Levitin, Gregory; Hausken, Kjell; Dai, Yuanshun

    2014-01-01

    The article considers a system consisting of identical elements. Each element can be protected individually. The groups of elements can have overarching protection. To destroy an element having both types of protections the attacker must always penetrate/destroy the overarching protection and then destroy the individual protection of the element. Both the attacker and the defender have limited resources. The resources needed to defend and attack the overarching protection are fixed, as is also the number of elements that can be protected by single overarching protection. The defender chooses the number of overarching protections and the number of individual protections within each protected group to minimize the expected damage caused by the attack. The attacker chooses the number of attacked overarching protections and after attacking the overarching protections it chooses the number of attacked elements to maximize the expected damage. The three period minmax game is formulated and an enumerative procedure for its solving is suggested. The influence of the game parameters on the optimal defense and attack strategies is discussed

    Preterm birth is a major public health problem in developed countries. In this context, we have conducted research into outpatient monitoring of uterine electrical activity in women at risk of preterm delivery. The objective of this preliminary study was to perform automated detection of uterine contractions (without human intervention or tocographic signal, TOCO) by processing the EHG recorded on the abdomen of pregnant women. The feasibility and accuracy of uterine contraction detection based on EHG processing were tested and compared to expert decision using external tocodynamometry (TOCO) . The study protocol was approved by local Ethics Committees under numbers ID-RCB 2016-A00663-48 for France and VSN 02-0006-V2 for Iceland. Two populations of women were included (threatened preterm birth and labour) in order to test our system of recognition of the various types of uterine contractions. EHG signal acquisition was performed according to a standardized protocol to ensure optimal reproducibility of EHG recordings. A system of 18 Ag/AgCl surface electrodes was used by placing 16 recording electrodes between the woman's pubis and umbilicus according to a 4 × 4 matrix. TOCO was recorded simultaneously with EHG recording. EHG signals were analysed in real-time by calculation of the nonlinear correlation coefficient H 2 . A curve representing the number of correlated pairs of signals according to the value of H 2 calculated between bipolar signals was then plotted. High values of H 2 indicated the presence of an event that may correspond to a contraction. Two tests were performed after detection of an event (fusion and elimination of certain events) in order to increase the contraction detection rate. The EHG database contained 51 recordings from pregnant women, with a total of 501 contractions previously labelled by analysis of the corresponding tocographic recording. The percentage recognitions obtained by application of the method based on coefficient H 2 was

    The discriminatory potency of variable number of tandem repeats (VNTR), based on 7 loci (MIRU 26, 27 and 5 ETRs A, B, C, D, E) was assayed on Mycobacterium bovis strains obtained from samples due to tuberculosis in two slaughterhouses in Algeria. The technique of MIRU-VNTR has been evaluated on 88 strains of M. bovis and one strain of M. caprea and shows 41 different profiles. Results showed that the VNTR were highly discriminatory with an allelic diversity of 0.930 when four loci (ETR A, B, C and MIRU 27) were highly discriminatory (h>0.25) and three loci (ETR D and E MIRU 26) moderately discriminatory (0.11VNTR loci were highly discriminatory be adequate for the first proper differentiation of strains of M. bovis in Algeria. The VNTR technique has proved a valuable tool for further development and application of epidemiological research for the of tuberculosis transmission in Algeria.

  8. The Inclusion of Standard Terms in International Sales Contracts

    Directory of Open Access Journals (Sweden)

    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.

    2018-01-12

    Effective risk adjustment is an aspect that is more and more given weight on the background of competitive health insurance systems and vital healthcare systems. The risk structure of the providers plays a vital role in Pay for Performance. A prerequisite for optimal incentive-based service models is a (partial) dependence of the agent's returns on the provider's gain level. Integrated care systems as well as accountable care organisations (ACOs) in the US and similar concepts in other countries are advocated as an effective method of improving the performance of healthcare systems. These systems outline a payment and care delivery model that intends to tie provider reimbursements to predefined quality metrics. By this the total costs of care shall be reduced. Little is known about the contractual design and the main challenges of delegating "accountability" to these new kinds of organisations and/or contracts. The costs of market utilisation are highly relevant for the conception of healthcare contracts; furthermore information asymmetries and contract-specific investments are an obstacle to the efficient operation of ACOs. A comprehensive literature review on methods of designing contracts in Integrated Care was conducted. The research question in this article focuses on how reimbursement strategies, evaluation of measures and methods of risk adjustment can best be integrated in healthcare contracting. Each integrated care contract includes challenges for both payers and providers without having sufficient empirical data on both sides. These challenges are clinical, administrative or financial nature. Risk adjusted contracts ensure that the reimbursement roughly matches the true costs resulting from the morbidity of a population. If reimbursement of care provider corresponds to the actual expenses for an individual/population the problem of risk selection is greatly reduced. The currently used methods of risk adjustment have widely differing model and forecast

  13. Galilean contractions of W-algebras

    Directory of Open Access Journals (Sweden)

    Jørgen Rasmussen

    2017-09-01

    Full Text Available Infinite-dimensional Galilean conformal algebras can be constructed by contracting pairs of symmetry algebras in conformal field theory, such as W-algebras. Known examples include contractions of pairs of the Virasoro algebra, its N=1 superconformal extension, or the W3 algebra. Here, we introduce a contraction prescription of the corresponding operator-product algebras, or equivalently, a prescription for contracting tensor products of vertex algebras. With this, we work out the Galilean conformal algebras arising from contractions of N=2 and N=4 superconformal algebras as well as of the W-algebras W(2,4, W(2,6, W4, and W5. The latter results provide evidence for the existence of a whole new class of W-algebras which we call Galilean W-algebras. We also apply the contraction prescription to affine Lie algebras and find that the ensuing Galilean affine algebras admit a Sugawara construction. The corresponding central charge is level-independent and given by twice the dimension of the underlying finite-dimensional Lie algebra. Finally, applications of our results to the characterisation of structure constants in W-algebras are proposed.

    For the second year running, hospitals are spending more on clinical outsourcing than on business services. The Eleventh Annual Contract Services Survey shows that, in clinical areas, executives use outsourcing to acquire specialized expertise with cost savings secondary. Reducing costs and FTEs are the primary reasons for outsourcing business operations. Business service contracts are more likely to meet expectations for cost savings. Overall, satisfaction levels are up, but in some areas there's still a lot of room for improvement. This report examines current trends in outsourcing, strategies for the future, satisfaction levels, the decisionmaking process, contract features, and costs.

    2015-08-01

    Sponsored research increasingly requires multiinstitutional collaboration. However, research contracting procedures have become more complicated and time consuming. The perinatal research units of two colocated healthcare systems sought to improve their research contracting processes. The Lean Process, a management practice that iteratively involves team members in root cause analyses and process improvement, was applied to the research contracting process, initially using Process Mapping and then developing Problem Solving Reports. Root cause analyses revealed that the longest delays were the individual contract legal negotiations. In addition, the "business entity" was the research support personnel of both healthcare systems whose "customers" were investigators attempting to conduct interinstitutional research. Development of mutually acceptable research contract templates and language, chain of custody templates, and process development and refinement formats decreased the Notice of Grant Award to Purchase Order time from a mean of 103.5 days in the year prior to Lean Process implementation to 45.8 days in the year after implementation (p = 0.004). The Lean Process can be applied to interinstitutional research contracting with significant improvement in contract implementation. © 2015 Wiley Periodicals, Inc.

  6. A variable turbulent Prandtl and Schmidt number model study for scramjet applications

    Science.gov (United States)

    Keistler, Patrick

    A turbulence model that allows for the calculation of the variable turbulent Prandtl (Prt) and Schmidt (Sct) numbers as part of the solution is presented. The model also accounts for the interactions between turbulence and chemistry by modeling the corresponding terms. Four equations are added to the baseline k-zeta turbulence model: two equations for enthalpy variance and its dissipation rate to calculate the turbulent diffusivity, and two equations for the concentrations variance and its dissipation rate to calculate the turbulent diffusion coefficient. The underlying turbulence model already accounts for compressibility effects. The variable Prt /Sct turbulence model is validated and tuned by simulating a wide variety of experiments. Included in the experiments are two-dimensional, axisymmetric, and three-dimensional mixing and combustion cases. The combustion cases involved either hydrogen and air, or hydrogen, ethylene, and air. Two chemical kinetic models are employed for each of these situations. For the hydrogen and air cases, a seven species/seven reaction model where the reaction rates are temperature dependent and a nine species/nineteen reaction model where the reaction rates are dependent on both pressure and temperature are used. For the cases involving ethylene, a 15 species/44 reaction reduced model that is both pressure and temperature dependent is used, along with a 22 species/18 global reaction reduced model that makes use of the quasi-steady-state approximation. In general, fair to good agreement is indicated for all simulated experiments. The turbulence/chemistry interaction terms are found to have a significant impact on flame location for the two-dimensional combustion case, with excellent experimental agreement when the terms are included. In most cases, the hydrogen chemical mechanisms behave nearly identically, but for one case, the pressure dependent model would not auto-ignite at the same conditions as the experiment and the other

  8. Invalidity of contract: legislative regulation and types

    Directory of Open Access Journals (Sweden)

    Василь Іванович Крат

    2017-09-01

    Full Text Available Invalidity contracts always attracted attention researchers. Without regard to it, in modern conditions there is an enormous layer of the problems related to invalidity contract, that to require a doctrine and utilitarian comprehension. The article is sanctified to research invalidity contract. In the article analyses problems of the legislative regulation and types of invalidity contract through the prism of judicial practice. In the Civil code of Ukraine, a voidable contract sets as a common rule. A voidable of the contract is incarnated in the so-called «virtual» invalidity when only the most typical grounds are enumerated. However, even such approach does not allow to overcome all possible cases that arise up in practice. Such situation touches possibility of voidable contracts concluded with the purpose of to shut out the appeal of claim to the property of the debtor. Therefore it follows to set general rules in relation to voidable contracts of the debtor. A nullity of the contract takes place only in the case when there is the direct pointing of law on the qualification of that or another contract as the nullity. The nullity of contract in the Civil code of Ukraine is constructed by means of «textual» invalidity. There are no single attempts to use the construction of «virtual» invalidity in judicial practice when there is the direct pointing of law on the qualification of that or another contract as the nullity, that is impermissible. Methodologically incorrectly to carry out identifying of invalidity contract and obligation with the aim of providing of application of different after the rich in content filling norms.

    Directory of Open Access Journals (Sweden)

    Rozhan Othman

    2005-09-01

    Full Text Available A psychological contract is an implicit understanding between a group of employees and their employer that arose as a result of a particular leadership style. Psychological contract violation (PCV is said to occur when there is a perceived breach of promise that leads to an emotional and affective response. The literature on PCV posits a number of antecedents and outcomes of PCV. This study seeks to develop a model of PCV by linking it with justice and organizational citizenship behavior (OCB. It is argued that the antecedents of PCV lead to a sense of  injustice. These will then create the emotional response that is indicative of PCV. It is also argued that an outcome of this PCV experience is reduced OCB and the emergence of a new outlook towards employment relationship. Data was collected from a Malaysian company that initiated a voluntary separation scheme as part of an effort to downsize its work force. The finding of this study provides partial support for the model.

    Because corruption must be hidden from the public and is not enforced by courts it entails transaction costs, which are larger than those from legal exchange. This suggests that corrupt contracts are primarily relational contracts where legal exchange serves as a basis for sealing and enforcing corrupt agreements.

    Tessier, C

    1992-03-01

    Contract medical transcription services can be of great assistance in meeting the demands for transcription, without jeopardizing patient, physician, or institutional confidentiality. You simply must require the contract service to provide at least the same degree of protection and preservation of confidentiality that you should require inhouse. To achieve this you must make these requirements explicit, comprehensive, comprehensible, believable, and enforceable. Discuss the requirements with prospective contractors. Review them at least annually with existing contractors and when contracts are due for renewal. Be sure to specify the consequence of breaching confidentiality, and if there are breaches, enforce the terms of the contract. Consult your institution's legal counsel both in developing the contract and in enforcing its provisions. Take into consideration your department's and institution's policies, AHIMA's statement on confidentiality, as well as local, state, and federal laws. Above all, never lose sight of the patient. Ultimately, it is not patient information that you are obligated to protect. It is the patient.

Hydro-Quebec exports could also replace power plants that would otherwise be needed in the USA. The economic environment for Hydro-Quebec exports to the USA is reviewed along with the regulatory environment applicable to international trade (General Agreement on Tariffs and Trade, Canada-USA Free Trade Agreement, North American Free Trade Agreement), Quebec (Canadian federal and provincial law), and the USA (federal and state law). A jurisdictional analysis of power export contracts is then presented, citing examples of contracts already signed by Hydro-Quebec with utilities in New York and New England. Contract law and contract provisions are discussed, including common clauses and particular clauses. Suggestions are made for new clauses that would improve the electricity trade. 215 refs., 13 figs., 3 tabs

  4. The Public Sector and Obligation to Contract

    DEFF Research Database (Denmark)

    Olesen, Karsten Naundrup; Indén, Tobias

    2016-01-01

    The paper concerns the situation where public sector bodies are forced to enter into contracts. These obligations to contract are analysed from two angles. First, the paper offers an analysis of the reasons for imposing such obligations to contract under Swedish and Danish law. Secondly the paper...... discusses some consequences of the public entities’ obligations to contract, more specific consequences for the use of rules that usually regulate contracts and the fact that obligations to contract imposed on public entities establish a new market and at the same time the obligations deprive the entities...... of the freedom to contract which is a fundamental to market behaviour. Finally attention is drawn to the fact that obligations to contract are also imposed on private entities. The paper takes Swedish and Danish regulations as a point of departure and provides an insight into regulations from these two countries...

  7. Contract Design: Risk Management and Evaluation

    Directory of Open Access Journals (Sweden)

    Axel C. Mühlbacher

    2018-01-01

    Full Text Available Introduction: Effective risk adjustment is an aspect that is more and more given weight on the background of competitive health insurance systems and vital healthcare systems. The risk structure of the providers plays a vital role in Pay for Performance. A prerequisite for optimal incentive-based service models is a (partial dependence of the agent’s returns on the provider’s gain level. Integrated care systems as well as accountable care organisations (ACOs in the US and similar concepts in other countries are advocated as an effective method of improving the performance of healthcare systems. These systems outline a payment and care delivery model that intends to tie provider reimbursements to predefined quality metrics. By this the total costs of care shall be reduced.  Methods: Little is known about the contractual design and the main challenges of delegating “accountability” to these new kinds of organisations and/or contracts. The costs of market utilisation are highly relevant for the conception of healthcare contracts; furthermore information asymmetries and contract-specific investments are an obstacle to the efficient operation of ACOs. A comprehensive literature review on methods of designing contracts in Integrated Care was conducted. The research question in this article focuses on how reimbursement strategies, evaluation of measures and methods of risk adjustment can best be integrated in healthcare contracting.  Results: Each integrated care contract includes challenges for both payers and providers without having sufficient empirical data on both sides. These challenges are clinical, administrative or financial nature. Risk adjusted contracts ensure that the reimbursement roughly matches the true costs resulting from the morbidity of a population. If reimbursement of care provider corresponds to the actual expenses for an individual/population the problem of risk selection is greatly reduced. The currently used methods

  8. Torque decrease during submaximal evoked contractions of the quadriceps muscle is linked not only to muscle fatigue.

    2015-05-01

    The aim of this study was to analyze the neuromuscular mechanisms involved in the torque decrease induced by submaximal electromyostimulation (EMS) of the quadriceps muscle. It was hypothesized that torque decrease after EMS would reflect the fatigability of the activated motor units (MUs), but also a reduction in the number of MUs recruited as a result of changes in axonal excitability threshold. Two experiments were performed on 20 men to analyze 1) the supramaximal twitch superimposed and evoked at rest during EMS (Experiment 1, n = 9) and 2) the twitch response and torque-frequency relation of the MUs activated by EMS (Experiment 2, n = 11). Torque loss was assessed by 15 EMS-evoked contractions (50 Hz; 6 s on/6 s off), elicited at a constant intensity that evoked 20% of the maximal voluntary contraction (MVC) torque. The same stimulation intensity delivered over the muscles was used to induce the torque-frequency relation and the single electrical pulse evoked after each EMS contraction (Experiment 2). In Experiment 1, supramaximal twitch was induced by femoral nerve stimulation. Torque decreased by ~60% during EMS-evoked contractions and by only ~18% during MVCs. This was accompanied by a rightward shift of the torque-frequency relation of MUs activated and an increase of the ratio between the superimposed and posttetanic maximal twitch evoked during EMS contraction. These findings suggest that the torque decrease observed during submaximal EMS-evoked contractions involved muscular mechanisms but also a reduction in the number of MUs recruited due to changes in axonal excitability.

  9. Variability and decline in the number of severe tropical cyclones making land-fall over eastern Australia since the late nineteenth century

    Recent studies have raised concerns that tropical cyclones (TCs), particularly severe TCs, have become more frequent in many places in response to global warming. Other studies discuss errors in TC data that can cause large inaccuracies in some of the observed trends. Additional studies conclude that TCs are likely to become more intense in the future in response to global warming, while regional modelling studies for the south-west Pacific near north-eastern Australia project an intensification of TCs and either a decrease or no change in TC numbers. Here we describe and use a new data base of severe land-falling TCs for eastern Australia derived from numerous historical sources, that has taken over a decade to develop. It provides one of the world's longest reliable records of tropical cyclone activity, and allows us to document changes over much longer periods than has been done previously for the Southern Hemisphere. Land-fall numbers are shown to vary a great deal on interannual, decadal and longer time-scales. The interannual variability is consistent with previous studies using much shorter data sets: land-fall numbers are well-simulated as a Poisson process and are modulated by the El Nino-Southern Oscillation (ENSO). Land-falls occurred almost twice as often in La Nina years as they did in El Nino years, and multiple land-falls only occurred during La Nina years. The statistical link between land-falls and pre-season values of the Southern Oscillation Index provides a modest predictive capability. Decadal variability in ENSO drives some of the decadal variability in land-fall numbers. The sign and magnitude of trends calculated over 30 years periods vary substantially, highlighting that caution needs to be taken in making inferences about trends based on e.g. satellite era data only. The linear trend in the number of severe TCs making land-fall over eastern Australia declined from about 0.45 TCs/year in the early 1870s to about 0.17 TCs/year in recent

    Propionibacterium acnes plays a central role in the pathogenesis of acne and is responsible for severe opportunistic infections. Numerous typing schemes have been developed that allow the identification of phylotypes, but they are often insufficient to differentiate subtypes. To better understand the genetic diversity of this species and to perform epidemiological analyses, high throughput discriminant genotyping techniques are needed. Here we describe the development of a multiple locus variable number of tandem repeats (VNTR) analysis (MLVA) method. Thirteen VNTRs were identified in the genome of P. acnes and were used to genotype a collection of clinical isolates. In addition, publically available sequencing data for 102 genomes were analyzed in silico, providing an MLVA genotype. The clustering of MLVA data was in perfect congruence with whole genome based clustering. Analysis of the clustered regularly interspaced short palindromic repeat (CRISPR) element uncovered new spacers, a supplementary source of genotypic information. The present MLVA13 scheme and associated internet database represents a first line genotyping assay to investigate large number of isolates. Particular strains may then be submitted to full genome sequencing in order to better analyze their pathogenic potential. Copyright © 2015 Elsevier B.V. All rights reserved.

    Standard form of contract is normally being used in Malaysia construction industry in establishing legal relation between contracting parties. Generally, most of Malaysia federal government construction project used PWD203A which is a standard form of contract to be used where Bills of Quantities Form Part of the Contract and it is issued by Public Works Department (PWD/JKR). On the other hand in Sarawak, the largest state in Malaysia, the state government has issued their own standard form of contract namely JKR Sarawak Form of Contract 2006. Even both forms have been used widely in construction industry; there is still lack of understanding on both forms. The aim of this paper is to identify significant provision on both forms of contract. Document analysis has been adopted in conducting an in-depth review on both forms. It is found that, both forms of contracts have differences and similarities on several provisions specifically matters to definitions and general; execution of the works; payments, completion and final account; and delay, dispute resolution and determination.

  14. Contraction of the solar nebula

    Rawal, J.J.

    1984-01-01

    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 is operative and brings about the halt at various stages of contraction. It is found that the radius of the contracting solar nebula follows the Titius-Bode law. The consequences of the relation are also discussed. The aim is to 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. (Auth.)

  20. Impact of employment contract changes on workers' quality of working life, job insecurity, health and work-related attitudes.

    Changes in employment contracts may impact the quality of working life, job insecurity, health and work-related attitudes. We examined the validity of two partly competing theoretical approaches. Based upon a segmentation approach, we expected no change in scores among stable trajectories, whereas upward trajectories were expected to be for the better and downward trajectories to be for the worse (Hypothesis 1). As turnover theories suggest that this hypothesis may only apply to workers who do not change employer, we also examined these contract trajectories stratified for a change of employer (Hypothesis 2). Drawing on the 2007 and 2008 waves of the Netherlands Working Conditions Cohort Study (N=9,688), repeated measures analysis of covariance showed little across-time change in the criterion variables, thus largely disconfirming our first hypothesis. These results could (at least partly) be explained by employer change; this was generally associated with improved scores among all contract trajectories (Hypothesis 2). However, workers receiving a less stable contract from the same employer were found to be at risk for health and well-being problems. Segmentation theory-based assumptions on contract trajectories primarily apply to stable and downward contract trajectories at the same employer, whereas assumptions from turnover theories better apply to contract trajectories combined with a change of employer. Future research should focus more closely on factors predicting "involuntary" downward trajectories into precarious temporary employment or unemployment.
