  6. Renewable portfolio standard and certificates trading on the Dutch electricity market

    International Nuclear Information System (INIS)

    Drillsch, J.

    2001-01-01

    In 1996, the Dutch distribution companies signed a voluntary agreement to reduce CO 2 emissions. As one element of the agreement a renewable portfolio standard (RPS) for the electricity distribution companies with certificates trading was introduced (green label system). The analysis reveals that the total volume of the obligation (3%) can be considered as modest. In addition, it seems more appropriate to replace the distribution companies' current monopoly for the issuing of the certificates by an independent institution. A flexibility mechanism (e.g., a certificates' banking system), which prevents high volatilities in the certificates' market price, and a clear sanction mechanism is needed. A drawback of the current Dutch system is the discriminatory financing of the RPS, which is only provided by MAP tariff customers. Nevertheless, the Dutch RPS may induce an efficient allocation of financial means to support renewable energies. It provides valuable experiences in the functioning of the new system, from which other countries may gain. (author)

  7. Public healthcare interests require strict competition enforcement.

    Loozen, Edith M H

    2015-07-01

    Several countries have introduced competition in their health systems in order to maintain the supply of high quality health care in a cost-effective manner. The introduction of competition triggers competition enforcement. Since healthcare is characterized by specific market failures, many favor healthcare-specific competition enforcement in order not only to account for the competition interest, but also for the healthcare interests. The question is whether healthcare systems based on competition can succeed when competition enforcement deviates from standard practice. This paper analyzes whether healthcare-specific competition enforcement is theoretically sound and practically effective. This is exemplified by the Dutch system that is based on regulated competition and thus crucially depends on getting competition enforcement right. Governments are responsible for correcting market failures. Markets are responsible for maximizing the public healthcare interests. By securing sufficient competitive pressure, competition enforcement makes sure they do. When interpreted according to welfare-economics, competition law takes into account both costs and benefits specific market behavior may have for healthcare. Competition agencies and judiciary are not legitimized to deviate from standard evidentiary requirements. Dutch case law shows that healthcare-specific enforcement favors the healthcare undertakings concerned, but to the detriment of public health care. Healthcare-specific competition enforcement is conceptually flawed and counterproductive. In order for healthcare systems based on competition to succeed, competition enforcement should be strict.

  8. Pragmatics of policy: the compliance of dutch environmental policy instruments to European union standards.

    Kruitwagen, Sonja; Reudink, Melchert; Faber, Albert

    2009-04-01

    Despite a general decrease in Dutch environmental emission trends, it remains difficult to comply with European Union (EU) environmental policy targets. Furthermore, environmental issues have become increasingly complex and entangled with society. Therefore, Dutch environmental policy follows a pragmatic line by adopting a flexible approach for compliance, rather than aiming at further reduction at the source of emission. This may be politically useful in order to adequately reach EU targets, but restoration of environmental conditions may be delayed. However, due to the complexity of today's environmental issues, the restoration of environmental conditions might not be the only standard for a proper policy approach. Consequently this raises the question how the Dutch pragmatic approach to compliance qualifies in a broader policy assessment. In order to answer this question, we adapt a policy assessment framework, developed by Hemerijck and Hazeu (Bestuurskunde 13(2), 2004), based on the dimensions of legitimacy and policy logic. We apply this framework for three environmental policy assessments: flexible instruments in climate policy, fine-tuning of national and local measures to meet air quality standards, and derogation for the Nitrate Directive. We conclude with general assessment notes on the appliance of flexible instruments in environmental policy, showing that a broad and comprehensive perspective can help to understand the arguments to put such policy instruments into place and to identify trade-offs between assessment criteria.

  9. [The revised Dutch College of General Practitioners' standard on COPD and the first international WHO standard: differences and similarities].

    van Schayck, C P

    2002-02-23

    Two standards on COPD have recently been published: the revised national standard from the Dutch College of General Practitioners and the first international standard published by the World Health Organization and the US National Heart, Lung and Blood Institute. The reduced emphasis on the role of spirometry in the monitoring and evaluation of treatment is an important change in these new standards compared to previous ones. Cessation of smoking is considered to be central to the prevention and treatment of COPD. Doctors should strongly support this approach and, more than before, are urged to view COPD as a disease caused by addiction. Bronchodilators are the cornerstone of symptomatic treatment of COPD, particularly the long-acting ones due to their ease of administration and effective treatment of morning dyspnoea. Inhalation corticosteroids should only be administered as a trial treatment and only under certain conditions. Continuation of treatment with these agents is only justified if there is a demonstrated improvement in lung function, exacerbations or symptoms, although the precise area of indication is not yet clear.

  10. Development of the Dutch primary standard for beta-emitting brachytherapy sources

    International Nuclear Information System (INIS)

    Marel, J. an der; Dijk, E. van

    2002-01-01

    The application of β-radiation emitting radioactive sources in medicine is rapidly expanding. An important new application is the use of β-radiation emitting radioactive sources in endovascular brachytherapy to avoid restenosis. Another well-known application is the use of the ophthalmic applicator (flat or concave surface source) for the treatment of tumors in the eye. Dose and dose distributions are very important characteristics of brachytherapy sources. The absorbed dose in the treated tissue should be known accurately to assure a good quality of the treatment and to develop new treatment methods and source configurations. At the Nederland s Meetinstituut (NMi) a project is going on for the development of a primary standard for betadosimetry. With this standard, dose and dose distributions of β-sources as used in brachytherapy can be measured in terms of absorbed dose to water. The primary standard is based on an extrapolation chamber. The extrapolation chamber will become part of a quality assurance system in Dutch hospitals for endovascular brachytherapy sources. The quality assurance system will further consist of transfer standards like well-type ionisation chambers, plastic scintillator systems and radiochromic film dosimetry. Apart from the endovascular sources the extrapolation chamber will be used to characterize ophthalmic applicators

    Accurate calculations of testicular volume standard deviation (SD) scores are not currently available. We constructed LMS-smoothed age-reference charts for testicular volume in healthy boys. The LMS method was used to calculate reference data, based on testicular volumes from ultrasonography and Prader orchidometer of 769 healthy Dutch boys aged 6 months to 19 years. We also explored the association between testicular growth and pubic hair development, and data were compared to orchidometric testicular volumes from the 1997 Dutch nationwide growth study. The LMS-smoothed reference charts showed that no revision of the definition of normal onset of male puberty - from nine to 14 years of age - was warranted. In healthy boys, the pubic hair stage SD scores corresponded with testicular volume SD scores (r = 0.394). However, testes were relatively small for pubic hair stage in Klinefelter's syndrome and relatively large in immunoglobulin superfamily member 1 deficiency syndrome. The age-corrected SD scores for testicular volume will aid in the diagnosis and follow-up of abnormalities in the timing and progression of male puberty and in research evaluations. The SD scores can be compared with pubic hair SD scores to identify discrepancies between cell functions that result in relative microorchidism or macroorchidism. ©2015 Foundation Acta Paediatrica.

    Strictness analysis has been a living field of investigation since Mycroft's original work in 1980, and is getting increasingly significant with the still wider use of lazy functional programming languages. This paper focuses on an actual implementation of a strictness analyser for Haskell....... The analyser uses abstract interpretation with chaotic fixpoint iteration. The demand-driven nature of this iteration technique allows us to use large domains including function domains in the style of Burn et al. 1986 and Wadler 87 and retain reasonable efficiency. The implementation, furthermore, allows us...

  8. The trend to get strict

    International Nuclear Information System (INIS)

    Clarke, Chris.

    1997-01-01

    Most policy makers in the USA and Europe are committed to strict environmental liability. The polluter pays principle is seen as popular with voters and easy to defend. For the energy sector, encompassing everything from disused gas works and coal mines to refineries, tank farms and filling stations, the cost of cleaning up old sites can be huge. Within the policy commitment to strict liability there are some issues up for negotiation, however. These include such things as: available defences; the burden of proof; mechanisms for sharing liability at multi-party sites; funding of orphan shares; the protection afforded to lenders. Most governments have shown some flexibility on these issues and some examples from the USA are given. Nevertheless, in Europe the momentum towards comprehensive strict liability regimes seems unrelenting. In the Member states of the European Union, liability laws are either already in place or new laws are in preparation. The European Commission is working on proposals for an EU-wide environmental liability regime but there are formidable obstacles to overcome if it is to become EU law. In the meanwhile, the process of trying to reach agreement at an EU level is likely to strengthen the legislative drive at national level. (UK)

    The civil strict liability regime of the electronuclear industry is a fundamental variable for preventing risk. Because prices of other energies as oil or gas are becoming higher and unpredictable, nuclear power becomes cost-effective and may favour the partial privatization of nuclear parks. By considering theoretical traditional liability models, we study the conditions that ensure the most efficient safety level when comparing natural monopoly situation and Bertrand duopoly. Our results are that natural monopoly is safer than duopoly only when strict liability is fully applied. We define conditions that neutralize risk for applying some privatization plan to nuclear park

    2011-01-01

    Full Text Available Abstract Background The use of thrombolytic therapy in the treatment of thrombosed infrainguinal native arteries and bypass grafts has increased over the years. Main limitation of this treatment modality, however, is the occurrence of bleeding complications. Low intensity ultrasound (US has been shown to accelerate enzymatic thrombolysis, thereby reducing therapy time. So far, no randomized trials have investigated the application of US-accelerated thrombolysis in the treatment of thrombosed infra-inguinal native arteries or bypass grafts. The DUET study (Dutch randomized trial comparing standard catheter-directed thrombolysis versus Ultrasound-accElerated Thrombolysis for thrombo-embolic infrainguinal disease is designed to assess whether US-accelerated thrombolysis will reduce therapy time significantly compared with standard catheter-directed thrombolysis. Methods/design Sixty adult patients with recently (between 1 and 7 weeks thrombosed infrainguinal native arteries or bypass grafts with acute limb ischemia class I or IIa, according to the Rutherford classification for acute ischemia, will be randomly allocated to either standard thrombolysis (group A or US-accelerated thrombolysis (group B. Patients will be recruited from 5 teaching hospitals in the Netherlands during a 2-year period. The primary endpoint is the duration of catheter-directed thrombolysis needed for uninterrupted flow in the thrombosed infrainguinal native artery or bypass graft, with outflow through at least 1 crural artery. Discussion The DUET study is a randomized controlled trial that will provide evidence of whether US-accelerated thrombolysis will significantly reduce therapy time in patients with recently thrombosed infrainguinal native arteries or bypass grafts, without an increase in complications.

  3. Dynamic Enforcement of the Strict Integrity Policy

    2005-01-01

    The Strict integrity policy (SIP) in Biba's integrity model is widely used in protecting information integrity, but the static integrity labels of both subjects and objects increase compatibility cost of applications and might prevent some operations that are indeed harmless.In order to improve compatibility, Dynamic enforcement of the Strict integrity policy (DESIP) is put forward. The current integrity label attribute of a subject in SIP is replaced with two attributes in DESIP, which are used to confine dynamically the range of objects a subject could be allowed to access. The new rules of access control in DESIP are given for each kind of access mode (observe,modify and invoke) together with the proofs of their valid-ity. Comparison between SIP and DESIP shows that after a sequence of operations, a subject controlled by DESIP tends to behave in a similar way as it is controlled by SIP and DESIP is more compatible than SIP.

  4. A strictly hyperbolic equilibrium phase transition model

    International Nuclear Information System (INIS)

    Allaire, G; Faccanoni, G; Kokh, S.

    2007-01-01

    This Note is concerned with the strict hyperbolicity of the compressible Euler equations equipped with an equation of state that describes the thermodynamical equilibrium between the liquid phase and the vapor phase of a fluid. The proof is valid for a very wide class of fluids. The argument only relies on smoothness assumptions and on the classical thermodynamical stability assumptions, that requires a definite negative Hessian matrix for each phase entropy as a function of the specific volume and internal energy.

    This paper explores the extent to which markets constrain intertemporal preferences. First, we show that without transaction costs, agents are immune to exploitation in competitive markets. In particular, a sequence of trades leaving any market participant strictly worse off (termed a money losing Dutch book) is generically impossible. When transaction costs exist in the market, Dutch books are plausible only when agents have inaccurate beliefs about their own future behavior. Thus, markets a...

    The proposal by the Dutch to extract natural gas from the 40 billion cubic metres beneath the Wadden Sea has been cited as a serious cause for concern by environmentalists. The new right wing government is less concerned than was the recently ousted left wing government and stands to gain directly through increased revenue. The Wadden Sea is a vast area of tidal channels, mudflats, shifting sandbanks, salt marshes, wet meadows and dunes, and provides a safe haven for numerous protected plants and animals. It is also a sanctuary for migrating birds and a feeding ground for herring, sole and plaice. Subsidence is cited by the environmentalists as a major potential problem and pollution is said to be always a risk.

  14. Effects of a strict cutoff on Quantum Field Theory

    International Nuclear Information System (INIS)

    Sturnfield, J.F.

    1987-01-01

    Standard Quantum Field Theory has a number of integrals which are infinite. Although these are eliminated for some cases by renormalization, this aspect of the theory is not fully satisfactory. A number of theories with fundamental lengths have been introduced as alternatives and it would be useful to be able to distinguish between them. In particular, the effects that a strict cutoff would have on Quantum Field Theory is studied. It is noted that care must be taken in the method used to apply a strict cutoff. This lead to considering a theory where the cutoffs are defined by restricting each internal line. This theory is only piece-wise analytic. The resulting scattering matrix is frame dependent, yet the theory still satisfies the special relativity view that all frames are subjectively identical. The renormalization of this theory is finite. The change in mass from the electron self-energy will be a spinor operator. The main distinctions of this theory from standard theory will occur at super high energies. New poles and resonances which arise from new endpoint singularities will be found. The locations of these singularities will be frame dependent. Some of these singularities will correspond to creations or interactions of the normal particles with tachyons. It will be shown that for the one loop diagram, the form of the cutoff singularities are closely related to the standard singularities. When there is more than one loop, there can appear some new type of behavior. In particular, a cube root type of behavior in the two loop self-energy diagram will be found. Also the asymptotic behavior of the ladder diagram is studied

  18. Synchronizing strict-feedback and general strict-feedback chaotic systems via a single controller

    International Nuclear Information System (INIS)

    Chen Shihua; Wang Feng; Wang Changping

    2004-01-01

    We present a systematic design procedure to synchronize a class of chaotic systems in a so-called strict-feedback form based on back-stepping procedure. This approach needs only a single controller to realize synchronization no matter how many dimensions the chaotic system contains. Furthermore, we point out that the method does not work for general strict-feedback chaotic systems, for instance, Lorenz system. Therefore, we propose three kinds of synchronization schemes for Lorenz system using the Lyapunov function method. All the three schemes avoid including divergence factor as in Ref. [Chaos, Solitons and Fractals 16 (2003) 37]. Especially in the last two schemes, we need only one state variable in controller, which has important significance in chaos synchronization used for communication purposes. Finally numerical simulations are provided to show the effectiveness and feasibility of the developed methods

    This study concerns the normal form and synchronization of strict-feedback chaotic systems. We prove that, any strict-feedback chaotic system can be rendered into a normal form with a invertible transform and then a design procedure to synchronize the normal form of a non-autonomous strict-feedback chaotic system is presented. This approach needs only a scalar driving signal to realize synchronization no matter how many dimensions the chaotic system contains. Furthermore, the Roessler chaotic system is taken as a concrete example to illustrate the procedure of designing without transforming a strict-feedback chaotic system into its normal form. Numerical simulations are also provided to show the effectiveness and feasibility of the developed methods

This is motivated by a model used in mathematical finance (the Heston model), and adds a new item to the zoology of non strictly convex large deviations. For one of these examples, we show that the rate function of the Cramer-type of large deviations coincides with that of the Freidlin-Wentzell when contraction principles are applied.

    Directory of Open Access Journals (Sweden)

    2015-02-01

    Full Text Available Following Den Besten’s (2009 desiderata for historical linguistics of Afrikaans, this article aims to contribute some modern evidence to the debate regarding the founding dialects of Afrikaans. From an applied perspective (i.e. human language technology, we aim to determine which West Germanic language(s and/or dialect(s would be best suited for the purposes of recycling speech resources for the benefit of developing speech technologies for Afrikaans. Being recognised as a West Germanic language, Afrikaans is first compared to Standard Dutch, Standard Frisian and Standard German. Pronunciation distances are measured by means of Levenshtein distances. Afrikaans is found to be closest to Standard Dutch. Secondly, Afrikaans is compared to 361 Dutch dialectal varieties in the Netherlands and North-Belgium, using material from the Reeks Nederlandse Dialectatlassen, a series of dialect atlases compiled by Blancquaert and Pée in the period 1925-1982 which cover the Dutch dialect area. Afrikaans is found to be closest to the South-Holland dialectal variety of Zoetermeer; this largely agrees with the findings of Kloeke (1950. No speech resources are available for Zoetermeer, but such resources are available for Standard Dutch. Although the dialect of Zoetermeer is significantly closer to Afrikaans than Standard Dutch is, Standard Dutch speech resources might be a good substitute.

  15. Strictly contractive quantum channels and physically realizable quantum computers

    International Nuclear Information System (INIS)

    Raginsky, Maxim

    2002-01-01

    We study the robustness of quantum computers under the influence of errors modeled by strictly contractive channels. A channel T is defined to be strictly contractive if, for any pair of density operators ρ, σ in its domain, parallel Tρ-Tσ parallel 1 ≤k parallel ρ-σ parallel 1 for some 0≤k 1 denotes the trace norm). In other words, strictly contractive channels render the states of the computer less distinguishable in the sense of quantum detection theory. Starting from the premise that all experimental procedures can be carried out with finite precision, we argue that there exists a physically meaningful connection between strictly contractive channels and errors in physically realizable quantum computers. We show that, in the absence of error correction, sensitivity of quantum memories and computers to strictly contractive errors grows exponentially with storage time and computation time, respectively, and depends only on the constant k and the measurement precision. We prove that strict contractivity rules out the possibility of perfect error correction, and give an argument that approximate error correction, which covers previous work on fault-tolerant quantum computation as a special case, is possible

    The Bayley Scales of Infant and Toddler Development-third edition (Bayley-III) are frequently used to assess early child development worldwide. However, the original standardization only included US children, and it is still unclear whether or not these norms are adequate for use in other populations. Recently, norms for the Dutch version of the Bayley-III (The Bayley-III-NL) were made. Scores based on Dutch and US norms were compared to study the need for population-specific norms. Scaled scores based on Dutch and US norms were compared for 1912 children between 14 days and 42 months 14 days. Next, the proportions of children scoring Dutch norms fluctuated around values based on US norms on all subtests. The extent of the deviations differed across ages and subtests. Differences in means were significant across all five subtests (p Dutch norms resulted in over-referral regarding gross motor skills, and under-referral regarding cognitive, receptive communication, expressive communication, and fine motor skills. The Dutch norms differ from the US norms for all subtests and these differences are clinically relevant. Population specific norms are needed to identify children with low scores for referral and intervention, and to facilitate international comparisons of population data.

For given x0∈H, the sequence xn is generated iteratively by xn+1=βnxn+1-βnTw1αnγfxn+I-μαnBTw2xn, ∀n∈N, where Twi=1−wiI+wiTi with i=1,2 and B:H→H is strongly monotone and Lipschitzian. Under some mild conditions on parameters αn and βn, we prove that the sequence xn converges strongly to the set FixT1∩FixT2 of fixed points of a pair of strictly pseudononspreading mappings T1 and T2.

    A strictly anaerobic bacterium was isolated from a continuous fermentor culture which converted the organic constituents of sulfite evaporator condensate to methane and carbon dioxide. Furfural is one of the major components of this condensate. This furfural isolate could degrade furfural as the sole source of carbon and energy in a defined mineral-vitamin-sulfate medium. Acetic acid was the major fermentation product. This organism could also use ethanol, lactate, pyruvate, or fumarate and c...

    We give an algorithm for minimizing the sum of a strictly convex function and a convex piecewise linear function. It extends several dual coordinate ascent methods for large-scale linearly constrained problems that occur in entropy maximization, quadratic programming, and network flows. In particular, it may solve exact penalty versions of such (possibly inconsistent) problems, and subproblems of bundle methods for nondifferentiable optimization. It is simple, can exploit sparsity, and in certain cases is highly parallelizable. Its global convergence is established in the recent framework of B -functions (generalized Bregman functions)

  10. Non-strictly black body spectrum from the tunnelling mechanism

    International Nuclear Information System (INIS)

    Corda, Christian

    2013-01-01

    The tunnelling mechanism is widely used to explain Hawking radiation. However, in many cases the analysis used to obtain the Hawking temperature only involves comparing the emission probability for an outgoing particle with the Boltzmann factor. Banerjee and Majhi improved this approach by explicitly finding a black body spectrum associated with black holes. Their result, obtained using a reformulation of the tunnelling mechanism, is in contrast to that of Parikh and Wilczek, who found an emission probability that is compatible with a non-strictly thermal spectrum. Using the recently identified effective state for a black hole, we solve this contradiction via a slight modification of the analysis by Banerjee and Majhi. The final result is a non-strictly black body spectrum from the tunnelling mechanism. We also show that for an effective temperature, we can express the corresponding effective metric using Hawking’s periodicity arguments. Potential important implications for the black hole information puzzle are discussed. -- Highlights: •We review an important result by Banerjee and Majhi on the tunnelling mechanism in the framework of Hawking radiation. •This result is in contrast to another result reported by Parikh and Wilczek. •We introduce the effective state of a black hole. •We explain the contrast via a slight modification of the analysis by Banerjee and Majhi. •We discuss potential important implications for the black hole information puzzle

    This article provides norms for general taboo, personal taboo, insult, valence, and arousal for 672 Dutch words, including 202 taboo words. Norms were collected using a 7-point Likert scale and based on ratings by psychology students from the Erasmus University Rotterdam in The Netherlands. The sample consisted of 87 psychology students (58 females, 29 males). We obtained high reliability based on split-half analyses. Our norms show high correlations with arousal and valence ratings collected by another Dutch word-norms study (Moors et al.,, Behavior Research Methods, 45, 169-177, 2013). Our results show that the previously found quadratic relation (i.e., U-shaped pattern) between valence and arousal also holds when only taboo words are considered. Additionally, words rated high on taboo tended to be rated low on valence, but some words related to sex rated high on both taboo and valence. Words that rated high on taboo rated high on insult, again with the exception of words related to sex many of which rated low on insult. Finally, words rated high on taboo and insult rated high on arousal. The Dutch Taboo Norms (DTN) database is a useful tool for researchers interested in the effects of taboo words on cognitive processing. The data associated with this paper can be accessed via the Open Science Framework ( https://osf.io/vk782/ ).

  13. Dutch euthanasia revisited.

    1997-01-01

    The results of a follow-up study of euthanasia by the Dutch government, five years after the first study, were published on November 26, 1996. This article provides a detailed review of the two reports comparing and contrasting the statistics cited therein. The author notes that the "rules of careful conduct" proposed by the courts and by the Royal Dutch Society of Medicine were frequently disregarded. Special topics included for the first time in the second study were the notification and non-prosecution procedure, euthanasia of newborns and infants, and assisted suicide in psychiatric practice. The authors of the follow-up report state that it would be desirable to reduce the number of "terminations of life without patients' request," but this must be the common responsibility of the doctor and the patient. They suggest that the person who does not wish to have his life terminated should declare this clearly, in advance, verbally and in writing, preferably in the form of a living will. Involuntary euthanasia was rampant in 1990 and equally rampant in 1995. The author concludes that Dutch doctors who practice euthanasia are not on the slippery slope. From the very beginning, they have been at the bottom.

    2014-11-15

    In this paper, we consider the problem of discriminating quantum states by local operations and classical communication (LOCC) when an arbitrarily small amount of error is permitted. This paradigm is known as asymptotic state discrimination, and we derive necessary conditions for when two multipartite states of any size can be discriminated perfectly by asymptotic LOCC. We use this new criterion to prove a gap in the LOCC and separable distinguishability norms. We then turn to the operational advantage of using two-way classical communication over one-way communication in LOCC processing. With a simple two-qubit product state ensemble, we demonstrate a strict majorization of the two-way LOCC norm over the one-way norm.

    Full Text Available The Bayley Scales of Infant and Toddler Development-third edition (Bayley-III are frequently used to assess early child development worldwide. However, the original standardization only included US children, and it is still unclear whether or not these norms are adequate for use in other populations. Recently, norms for the Dutch version of the Bayley-III (The Bayley-III-NL were made. Scores based on Dutch and US norms were compared to study the need for population-specific norms.Scaled scores based on Dutch and US norms were compared for 1912 children between 14 days and 42 months 14 days. Next, the proportions of children scoring < 1-SD and < -2 SD based on the two norms were compared, to identify over- or under-referral for developmental delay resulting from non-population-based norms.Scaled scores based on Dutch norms fluctuated around values based on US norms on all subtests. The extent of the deviations differed across ages and subtests. Differences in means were significant across all five subtests (p < .01 with small to large effect sizes (ηp2 ranging from .03 to .26. Using the US instead of Dutch norms resulted in over-referral regarding gross motor skills, and under-referral regarding cognitive, receptive communication, expressive communication, and fine motor skills.The Dutch norms differ from the US norms for all subtests and these differences are clinically relevant. Population specific norms are needed to identify children with low scores for referral and intervention, and to facilitate international comparisons of population data.

    Strict anaerobic gut microbes have been suggested as 'next-generation probiotics' for treating several intestinal disorders. The development of preservation techniques is of major importance for therapeutic application. This study investigated cryopreservation (-80°C) and lyophilization survival and storage stability (4°C for 3 months) of the strict anaerobic gut microbes Bacteroides thetaiotaomicron, Faecalibacterium prausnitzii, Roseburia intestinalis, Anaerostipes caccae, Eubacterium hallii and Blautia obeum. To improve preservation survival, protectants sucrose and inulin (both 5% w/v) were added for lyophilization and were also combined with glycerol (15% v/v) for cryopreservation. Bacterial fitness, evaluated by maximum growth rate and lag phase, viability and membrane integrity were determined using a standardized growth assay and by flow cytometry as markers for preservation resistance. Lyophilization was more detrimental to viability and fitness than cryopreservation, but led to better storage stability. Adding sucrose and inulin enhanced viability and the proportion of intact cells during lyophilization of all strains. Viability of protectant-free B. thetaiotaomicron, A. caccae and F. prausnitzii was above 50% after cryopreservation and storage and increased to above 80% if protectants were present. The addition of glycerol, sucrose and inulin strongly enhanced the viability of B. obeum, E. hallii and R. intestinalis from 0.03-2% in protectant-free cultures to 11-37%. This is the first study that quantitatively compared the effect of cryopreservation and lyophilization and the addition of selected protectants on viability and fitness of six strict anaerobic gut microbes. Our results suggest that efficiency of protectants is process- and species-specific. © 2018 The Authors.

  2. Efficient FPT Algorithms for (Strict) Compatibility of Unrooted Phylogenetic Trees.

    2017-04-01

    In phylogenetics, a central problem is to infer the evolutionary relationships between a set of species X; these relationships are often depicted via a phylogenetic tree-a tree having its leaves labeled bijectively by elements of X and without degree-2 nodes-called the "species tree." One common approach for reconstructing a species tree consists in first constructing several phylogenetic trees from primary data (e.g., DNA sequences originating from some species in X), and then constructing a single phylogenetic tree maximizing the "concordance" with the input trees. The obtained tree is our estimation of the species tree and, when the input trees are defined on overlapping-but not identical-sets of labels, is called "supertree." In this paper, we focus on two problems that are central when combining phylogenetic trees into a supertree: the compatibility and the strict compatibility problems for unrooted phylogenetic trees. These problems are strongly related, respectively, to the notions of "containing as a minor" and "containing as a topological minor" in the graph community. Both problems are known to be fixed parameter tractable in the number of input trees k, by using their expressibility in monadic second-order logic and a reduction to graphs of bounded treewidth. Motivated by the fact that the dependency on k of these algorithms is prohibitively large, we give the first explicit dynamic programming algorithms for solving these problems, both running in time [Formula: see text], where n is the total size of the input.

  3. Managing Hanford Site solid waste through strict acceptance criteria

    International Nuclear Information System (INIS)

    1993-02-01

    Various types of waste have been generated during the 50-year history of the Hanford Site. Regulatory changes in the last 20 years have provided the emphasis for better management of these wastes. Interpretations of the Atomic Energy Act of 1954 (AEA) and the Resource Conservation and Recovery Act of 1976 (RCRA) have led to the definition of a group of wastes called radioactive mixed wastes (RMW). As a result of the radioactive and hazardous properties of these wastes, strict management programs have been implemented for the management of these wastes. Solid waste management is accomplished through a systems performance approach to waste management that used best-demonstrated available technology (BDAT) and best management practices. The solid waste program at the Hanford Site strives to integrate all aspects of management relative to the treatment, storage and disposal (TSD) of solid waste. Often there are many competing and important needs. It is a difficult task to balance these needs in a manner that is both equitable and productive. Management science is used to help the process of making decisions. Tools used to support the decision making process include five-year planning, cost estimating, resource allocation, performance assessment, waste volume forecasts, input/output models, and waste acceptance criteria. The purpose of this document is to describe how one of these tools, waste acceptance criteria, has helped the Hanford Site manage solid wastes

    It is proved that the Mann iteration process converges strongly to the fixed point of a strictly hemi-contractive map in real uniformly smooth Banach spaces. The class of strictly hemi-contractive maps includes all strictly pseudo-contractive maps with nonempty fixed point sets. A related result deals with the Ishikawa iteration scheme when the mapping is Lipschitzian and strictly hemi-contractive. Our theorems generalize important known results. (author). 29 refs

  5. Optimal control of nonlinear continuous-time systems in strict-feedback form.

    Science.gov (United States)

    2015-10-01

    This paper proposes a novel optimal tracking control scheme for nonlinear continuous-time systems in strict-feedback form with uncertain dynamics. The optimal tracking problem is transformed into an equivalent optimal regulation problem through a feedforward adaptive control input that is generated by modifying the standard backstepping technique. Subsequently, a neural network-based optimal control scheme is introduced to estimate the cost, or value function, over an infinite horizon for the resulting nonlinear continuous-time systems in affine form when the internal dynamics are unknown. The estimated cost function is then used to obtain the optimal feedback control input; therefore, the overall optimal control input for the nonlinear continuous-time system in strict-feedback form includes the feedforward plus the optimal feedback terms. It is shown that the estimated cost function minimizes the Hamilton-Jacobi-Bellman estimation error in a forward-in-time manner without using any value or policy iterations. Finally, optimal output feedback control is introduced through the design of a suitable observer. Lyapunov theory is utilized to show the overall stability of the proposed schemes without requiring an initial admissible controller. Simulation examples are provided to validate the theoretical results.

  6. Dutch radiodiagnostics viewed internationally

    1990-01-01

    Dutch radiodiagnostics viewed internationally. - A quantitative description of diagnostic radiology is given in terms of radiological density (the number of radiological examinations per 1000 inhibitants), consumptions of roentgen film and contrast media. The data concerning examinations were recorded by a yearly inquiry system addressing all Dutch radiologists. The consumption of film and contrast media were derived from the data banks of the industries. In comparing these data with the data for Western Europe, Japan and the United States it is remarkable that diagnostic radiology scores lowest in regard to density, film consumption and use of contrast media. Only in the use of 35 mm cinefilm (coronary angiography) is The Netherlands number 2 on the list preceded by the United States. As a consequence radiation exposure of the population caused by diagnostic radiology is low in The Netherlands. Although the technical condition of the equipment is good due to regular and preventive service the life-span of the radiological equipment is gradually increasing beyond the limits of the normal economic depreciation. Growing arrears are found in the application of new technology: ultrasound, computer tomography and magnetic resonance imaging.

    The position is described of the different Dutch industries involved in the oil and gas exploitation business in the North Sea. Mentioned are, in the first place, the activities of towing services Smit Tak, and Wijsmuller. A well known drilling contractor is Neddrill. Drilling rigs are often designed in cooperation with consulting engineers firms Protech International, Heerema Engineering, Global Engineering, KTI, Fluor, and Tebodin. Drilling rigs constructors Grootint, Mercon Steel Structures, Heerema Havenbedrijf, HCG, Boele, and IHC have a sound name in the offshore construction scene. Offshore contractors like Heerema, Smit Tak, Volker Stevin and Allseas Engineering should be mentioned too. Special attention is given to the operation of saving drilling rigs in the Ekofisk field. Years of exploitation of oil and gas from this field resulted in subsidence of the sea floor, which endangered the drilling rigs. Hydraudyne designed the hydraulic lifter necessary for this saving operation. Dutch firms in this field have an estimated yearly turnover of Dfl 3 x 10/sup 9/. 6 figs.

    A retrospective consecutive case series to evaluate the safety and efficacy of 25 gauge pars plana vitrectomy, ILM peeling, 20% SF 6 gas tamponade and strict posturing for the treatment of idiopathic full-thickness macular holes. We report the results of 106 consecutive eyes that underwent standard 25-gauge pars plana vitrectomy, brilliant peel-assisted internal limiting membrane peel, fluid:gas exchange with 20% SF 6 and strict posturing for one week. All patients were followed up at one week, one month, three months, and nine months postoperatively. Biomicroscopy at day 1 and biomicroscopy and OCT at week 1, months 1, 3, and 9 were used to assess macular hole status postoperatively. Pre- and postoperative logMAR visual acuity was compared. The macular hole was closed in 102/106 eyes postoperatively (96.2%). Four eyes showed unclosed macular holes and underwent additional SF 6 intravitreal injection and strict posturing for 10 days. All macular holes were eventually closed without the need of a second surgical procedure. Mean visual acuity improved from 0.63 logMAR preoperatively to 0.39 logMAR postoperatively. One case of retinal toxicity was reported due to accidental intravitreal injection of antibiotic. 25-gauge vitrectomy, ILM peel, and short-acting gas tamponade are highly effective for the treatment of macular holes. Additional intravitreal gas injection followed by strict posturing seems to be a simple and effective treatment for unclosed holes.

  9. Strict or Graduated Punishment? Effect of Punishment Strictness on the Evolution of Cooperation in Continuous Public Goods Games

    Whether costly punishment encourages cooperation is one of the principal questions in studies on the evolution of cooperation and social sciences. In society, punishment helps deter people from flouting rules in institutions. Specifically, graduated punishment is a design principle for long-enduring common-pool resource institutions. In this study, we investigate whether graduated punishment can promote a higher cooperation level when each individual plays the public goods game and has the opportunity to punish others whose cooperation levels fall below the punisher’s threshold. We then examine how spatial structure affects evolutionary dynamics when each individual dies inversely proportional to the game score resulting from the social interaction and another player is randomly chosen from the population to produce offspring to fill the empty site created after a player’s death. Our evolutionary simulation outcomes demonstrate that stricter punishment promotes increased cooperation more than graduated punishment in a spatially structured population, whereas graduated punishment increases cooperation more than strict punishment when players interact with randomly chosen opponents from the population. The mathematical analysis also supports the results. PMID:23555826

    2010-01-01

    In this paper we present a semi-automatic method for femoral bone positioning after 3D image reconstruction from Computed Tomography images. This serves as grounding for the definition of strict axial, longitudinal and anterior-posterior views, overcoming the problem of patient positioning biases in 2D femoral bone measuring methods. After the bone reconstruction is aligned to a standard reference frame, new tomographic slices can be generated, on which unbiased measures may be taken. This could allow not only accurate inter-patient comparisons but also intra-patient comparisons, i.e., comparisons of images of the same patient taken at different times. This method could enable medical doctors to diagnose and follow up several bone deformities more easily.

    2007-01-01

    We consider the performance of small and medium sized enterprises in Dutch horticulture under different environmental policy regimes across time. We address the question whether technical performance differs under these alternative regulatory regimes to test Porter's hypothesis that stricter environmental regulation reduces technical inefficiency. For this purpose, we use a stochastic production frontier framework allowing for inclusion of policy variables to measure the effect of alternative environmental policy regimes on firms' performance. The main result is that stricter environmental policy regimes have indeed reduced technical inefficiencies in Dutch horticulture. The estimation results indicate amongst others that the 1997 agreement on energy, nutrient and pesticides use enhances technical efficiency. Firms under the strict environmental policy regime are found to be more technically efficient than those under a lax regime, thereby supporting the claims by Porter and Van der Linde (Porter, M., Van der Linde, C., 1995. Green and Competitive: Ending the stalemate. Harvard Business Review 73, pp. 120-137) concerning Dutch horticulture. (author)

    To decrease the risk of recurrence or metastasis in differentiated thyroid cancer (DTC), selected patients receive radioactive iodine ablation of remnant thyroid tissue or tumor. A low iodine diet can enhance uptake of radioactive iodine. We compared the success rates of radioactive iodine ablation therapy in patients who followed two different low iodine diets (LIDs). The success rates of postsurgical radioactive iodine ablation in DTC patients receiving empiric doses of 150 mCi were retrospectively reviewed. First-time radioactive iodine ablation therapy was done in 71 patients following less strict LID. Less strict LID restricted seafood, iodized salt, egg yolk, dairy products, processed meat, instant prepared meals, and multivitamins. Very strict LID additionally restricted rice, freshwater fish, spinach, and soybean products. Radioactive iodine ablation therapy was considered successful when follow up {sup 123I} whole body scan was negative and stimulated serum thyroglobulin level was less than 2.0 ng/mL. The success rate of patients following less strict LID was 80.3% and for very strict LID 75.6%. There was no statistically significant difference in the success rates between the two LID groups (P=0.48). Very strict LID may not contribute to improving the success rate of initial radioactive iodine ablation therapy at the cost of great inconvenience to the patient.

    2017-12-22

    In the Netherlands, the number of bariatric procedures increased exponentially in the 90s. To ensure and improve the quality of bariatric surgery, the nationwide Dutch Audit for Treatment of Obesity (DATO) was established in 2014. The audit was coordinated by the Dutch Institute for Clinical Auditing (DICA). This article provides a review of the aforementioned process in establishing a nationwide registry in the Netherlands. In collaboration with the DATO's scientific committee and other stakeholders, an annual list of several external quality indicators was formulated. This list consists of volume, process, and outcome indicators. In addition to the annual external indicators, the database permits individual hospitals to analyze their own data. The dashboard provides several standardized reports and detailed quality indicators, which are updated on a weekly base. Since the start, all 18 Dutch bariatric centers participated in the nationwide audit. A total of 21,941 cases were registered between 2015 and 2016. By 2016, the required variables were registered in 94.3% of all cases. A severe complicated course was seen in 2.87%, and mortality in 0.05% in 2016. The first-year follow-up shows a > 20% TWL in 86.1% of the registered cases. The DATO has become rapidly a mature registry. The well-organized structure of the national audit institution DICA and governmental funding were essential. However, most important were the bariatric teams themselves. The authors believe reporting the results from the registry has already contributed to more knowledge and acceptance by other health care providers.

  3. Strict Constraint Feasibility in Analysis and Design of Uncertain Systems

    Crespo, Luis G.; Giesy, Daniel P.; Kenny, Sean P.

    2006-01-01

    This paper proposes a methodology for the analysis and design optimization of models subject to parametric uncertainty, where hard inequality constraints are present. Hard constraints are those that must be satisfied for all parameter realizations prescribed by the uncertainty model. Emphasis is given to uncertainty models prescribed by norm-bounded perturbations from a nominal parameter value, i.e., hyper-spheres, and by sets of independently bounded uncertain variables, i.e., hyper-rectangles. These models make it possible to consider sets of parameters having comparable as well as dissimilar levels of uncertainty. Two alternative formulations for hyper-rectangular sets are proposed, one based on a transformation of variables and another based on an infinity norm approach. The suite of tools developed enable us to determine if the satisfaction of hard constraints is feasible by identifying critical combinations of uncertain parameters. Since this practice is performed without sampling or partitioning the parameter space, the resulting assessments of robustness are analytically verifiable. Strategies that enable the comparison of the robustness of competing design alternatives, the approximation of the robust design space, and the systematic search for designs with improved robustness characteristics are also proposed. Since the problem formulation is generic and the solution methods only require standard optimization algorithms for their implementation, the tools developed are applicable to a broad range of problems in several disciplines.

    Adrenal vein sampling (AVS) is intended to confirm unilateral forms of primary aldosteronism, which are amenable to surgical cure. Excessively strict AVS criteria to define lateralization may result in many patients incorrectly categorized as bilateral primary aldosteronism and opportunity for surgical cure missed. Retrospective review of an AVS-primary aldosteronism database in which surgical cases are verified by standardized outcomes. Having used 'less strict' AVS criteria for lateralization, we examined the distribution of AVS lateralization indices in our confirmed unilateral primary aldosteronism cases both with and without cosyntropin stimulation. The proportion of proven unilateral cases that would have been missed with stricter AVS interpretation criteria was calculated. Particular focus was given to the proportion of missed cases according to use of international guidelines. False-positive lateralization with 'less strict' interpretation was also calculated. Of 80 surgical primary aldosteronism cases, 10-23% would have been missed with AVS lateralization indices of 3 : 1 to 5 : 1, with or without cosyntropin. If strict selectivity indices (for confirmation of catheterization) were combined with strict lateralization indices, up to 70% of unilateral primary aldosteronism cases could have been missed. Use of Endocrine Society AVS guidelines would have missed 21-43% of proven unilateral cases. 'Less strict' AVS interpretation yielded one case (1.2%) of false lateralization. Excessively strict AVS interpretation criteria will result in a high rate of missed unilateral primary aldosteronism with subsequent loss of opportunity for intervention. Use of more lenient lateralization criteria will improve the detection rate of unilateral primary aldosteronism with very low false-positive rate.

    This Letter presents a novel cross active backstepping design method for synchronization control of cross-strict feedback hyperchaotic system, in which the ordinary backstepping design is unavailable. The proposed control method, combining backstepping design and active control approach, extends the application of backstepping technique in chaos control. Based on this method, different combinations of controllers can be designed to meet the needs of different applications. The proposed method is applied to achieve chaos synchronization of two identical cross-strict feedback hyperchaotic systems. Also it is used to implement synchronization between cross-strict feedback hyperchaotic system and Roessler hyperchaotic system. Numerical examples illustrate the validity of the control method

    We set out to address the adequacy of dyslexia screening in Dutch and non-western immigrant children, using the Dutch Dyslexia Screening Test (DST-NL) and outcomes of the Dutch dyslexia protocol, both of which are susceptible to cultural bias. Using the protocol as standard, we conducted an ROC (Receiver Operating Characteristics) analysis in Dutch and immigrant third, fifth, and seventh graders, combining a cross-sectional and longitudinal design. Sensitivity and specificity increased with grade, but were non-significant for various subtests in the lowest grade, suggesting considerable non-convergence between the two measures. Effective subtests in all grades, presumably not strongly influenced by Cultural Background or Word Lexicon, were One-Minute Reading, Non-Word Reading, and Nonsense Passage Reading. In a multilevel analysis, cultural background, dyslexia diagnosis, parental education, and grade of first assessment were predictors of subtest performance. In a second analysis, Word Lexicon was added as a proxy of knowledge of the Dutch language and culture. After controlling for Word Lexicon, cultural background became significant for most subtests, suggesting the presence of cultural bias. Subtests assessing technical literacy, such as One-Minute-Reading, Non-Word-Reading, One-Minute-Writing, or Two-Minutes-Spelling, showed more convergence between the two assessments. Less-effective subtests were Naming Pictures, Backward Digit Span, and Verbal and Semantic Fluency. It is concluded that the DST-NL and the standard protocol do not show complete convergence, notably in the lower grades in the multilingual pupil group of our cohort, mainly because dyslexia and literacy difficulties are hard to disentangle.

    Live identification procedures in England and Wales have been replaced by use of video, which provides a sequential presentation of facial images. Sequential presentation of photographs provides some protection to innocent suspects from mistaken identification when used with strict instructions designed to prevent relative judgements (Lindsay, Lea & Fulford, 1991). However, the current procedure in England and Wales is incompatible with these strict instructions. The reported research investi...

    Zhang, Jian-Guo

    1996-12-01

    Strict optical orthogonal codes are presented for purely asynchronous optical code-division multiple-access (CDMA) applications. The proposed code can strictly guarantee the peaks of its cross-correlation functions and the sidelobes of any of its autocorrelation functions to have a value of 1 in purely asynchronous data communications. The basic theory of the proposed codes is given. An experiment on optical CDMA systems is also demonstrated to verify the characteristics of the proposed code.

  10. Practice variation in the Dutch long-term care and the role of supply-sensitive care: Is access to the Dutch long-term care equitable?

    Universal access and generous coverage are important goals of the Dutch long-term care (LTC) system. It is a legal requirement that everyone eligible for LTC should be able to receive it. Institutional care (IC) made up for 90% of Dutch LTC spending. To investigate whether access to IC is as equitable as the Dutch government aspires, we explored practice variation in entitlements to IC across Dutch regions. We used a unique dataset that included all individual applications for Dutch LTC in January 2010-December 2013 (N = 3,373,358). This dataset enabled an accurate identification of the need for care. We examined the local variation in the probability of being granted long-term IC and in the intensity of the care granted given that individuals have applied for LTC. We also investigated whether the variation observed was related to differences in the local availability of care facilities. Although our analyses indicated the presence of some practice variation, its magnitude was very small by national and international standards (up to 3%). Only a minor part of the practice variation could be accounted for by local supply differences in care facilities. Overall, we conclude that, unlike many other developed countries, the Dutch system ensured equitable access to long-term IC. © 2017 The Authors. Health Economics Published by John Wiley & Sons Ltd.

  11. Design methodology of Dutch banknotes

    2000-04-01

    Since the introduction of a design methodology for Dutch banknotes, the quality of Dutch paper currency has improved in more than one way. The methodology is question provides for (i) a design policy, which helps fix clear objectives; (ii) design management, to ensure a smooth cooperation between the graphic designer, printer, papermaker an central bank, (iii) a program of requirements, a banknote development guideline for all parties involved. This systematic approach enables an objective selection of design proposals, including security features. Furthermore, the project manager obtains regular feedback from the public by conducting market surveys. Each new design of a Netherlands Guilder banknote issued by the Nederlandsche Bank of the past 50 years has been an improvement on its predecessor in terms of value recognition, security and durability.

    This study sought to investigate whether isolated abnormal strict morphology (<5% normal forms) and very low strict morphology (0-1% normal forms) affects pregnancy rates in intrauterine insemination (IUI). This was a retrospective study performed at an Academic Medical Center/Reproductive Medicine Center. Four hundred and eight couples were included for 856 IUI cycles. 70 IUI cycles were performed in couples with abnormal strict morphology and otherwise normal semen parameters. Outcomes were measured as clinical pregnancy rate per IUI cycle as documented by fetal heart activity on maternal ultrasound. Clinical pregnancy rate did not significantly differ between the group with abnormal strict morphology [11/70 (15.7%)] and the normal morphology group [39/281 (13.9%)]. Additionally, there was no significant difference between the pregnancy rate in the abnormal morphology group compared to that of our overall institutional IUI pregnancy rate [145/856 (16.9%)]. Furthermore, there was no significant difference between pregnancy rate in the very low morphology group [3/14 (21.4%)] compared to those with normal morphology or the overall IUI pregnancy rate. Patients with isolated abnormal strict morphology have clinical pregnancy rates similar to those with normal morphology for IUI. Even in those with very low normal forms, consideration of IUI for assisted reproduction should not be excluded. © 2015 American Society of Andrology and European Academy of Andrology.

    Full Text Available In the context in which transfer pricing may represent a mechanism through which multinationals have the possibility to move funds internationally, in order to prevent the base erosion and profit shifting between multinationals, countries over the world have adopted various transfer pricing regulations. Furthermore, some of the countries adopted stricter regulations than others. The objective of our research was to identify the level of strictness for the transfer pricing regulations from the European countries. To achieve this objective, we analyzed the transfer pricing regulations of all European countries and we built a transfer pricing strictness index, based on which we defined 4 categories of countries (where category 1 includes the countries with the least strict transfer pricing regulations and category 4 countries with the strictest regulations. After that, we illustrated how these categories are distributed on the European map. In order to collect the information, we used the transfer pricing guides issued by the Big Four companies for the year 2015. The study`s results show that the strictness of the transfer pricing regulations decreases from the west of Europe to east. Moreover, most of the countries were included in category 2, respectively category 3, meaning that the transfer pricing regulations from the European continent are not so flexible, but in the same time are not so strict.

  1. Dutch National Plan combat nuclear accidents

    International Nuclear Information System (INIS)

    1988-01-01

    This document presents the Dutch National Plan combat nuclear accidents (NPK). Ch. 2 discusses some important starting points which are determining for the framework and the performance of the NPK, in particular the accident typology which underlies the plan. Also the new accident-classification system for the Dutch nuclear power plants, the standardization for the measures to be taken and the staging around nuclear power plants are pursued. In ch. 3 the legal framework of the combat nuclear accidents is described. In particular the Nuclear-power law, the Accident law and the Municipality law are pursued. Also the role of province and municipality are described. Ch. 4 deals with the role of the owner/licensee of the object where the accident occurs, in the combat of accident. In ch. 5 the structure of the nuclear-accident combat at national level is outlined, subdivided in alarm phase, combat phase and the winding-up phase. In ch.'s 6-12 these phases are elaborated more in detail. In ch.'s 10-13 the measures to be taken in nuclear accidents, are described. These measures are distinguished with regard to: protection of the population and medical aspects, water economy, drinking-water supply, agriculture and food supply. Ch. 14 describes the responsibility of the burgomaster. Ch.'s 15 and 16 present an overview of the personnel, material, procedural and juridical modifications and supplements of existing structures which are necessary with regard to the new and modified parts of the structure. Ch. 17 indicates how by means of the appropriate education and exercise it can be achieved that all personnel, services and institutes concerned possess the knowledge and experience necessary for the activities from the NKP to be executed as has been described. Ch. 18 contains a survey of activities to be performed and a proposal how these can be realized. (H.W.). figs.; tabs

  2. R -Dimensional ESPRIT-Type Algorithms for Strictly Second-Order Non-Circular Sources and Their Performance Analysis

    2014-09-01

    High-resolution parameter estimation algorithms designed to exploit the prior knowledge about incident signals from strictly second-order (SO) non-circular (NC) sources allow for a lower estimation error and can resolve twice as many sources. In this paper, we derive the R-D NC Standard ESPRIT and the R-D NC Unitary ESPRIT algorithms that provide a significantly better performance compared to their original versions for arbitrary source signals. They are applicable to shift-invariant R-D antenna arrays and do not require a centrosymmetric array structure. Moreover, we present a first-order asymptotic performance analysis of the proposed algorithms, which is based on the error in the signal subspace estimate arising from the noise perturbation. The derived expressions for the resulting parameter estimation error are explicit in the noise realizations and asymptotic in the effective signal-to-noise ratio (SNR), i.e., the results become exact for either high SNRs or a large sample size. We also provide mean squared error (MSE) expressions, where only the assumptions of a zero mean and finite SO moments of the noise are required, but no assumptions about its statistics are necessary. As a main result, we analytically prove that the asymptotic performance of both R-D NC ESPRIT-type algorithms is identical in the high effective SNR regime. Finally, a case study shows that no improvement from strictly non-circular sources can be achieved in the special case of a single source.

  5. The photon is no strict particle and nonlocality is far from being proven

    2010-07-01

    Two aspects of philosophical discussions on physics are the wave particle dualism and non locality including entanglement. However the strict particle aspect of the photon, in the common sense view, has never been proven. The accumulation time argument, the only experimental verification of a strictly particle like photon, has so far not yet been satisfied. Also, experiments thought to prove nonlocality have loophole which have so far not yet been safely closed, and now an even more serious loophole emerges. Thus, also nonlocality cannot be seen as proven. This demands some fine tuning of philosophical discussions on critical experiments in physics.

    Full Text Available We introduce a new class of abstract structures, which we call generalized ultrametric semilattices, and in which the meet operation of the semilattice coexists with a generalized distance function in a tightly coordinated way. We prove a constructive fixed-point theorem for strictly contracting functions on directed-complete generalized ultrametric semilattices, and introduce a corresponding induction principle. We cite examples of application in the semantics of logic programming and timed computation, where, until now, the only tool available has been the non-constructive fixed-point theorem of Priess-Crampe and Ribenboim for strictly contracting functions on spherically complete generalized ultrametric semilattices.

    National parks and other protected areas are at the forefront of global efforts to protect biodiversity and ecosystem services. However, not all protection is equal. Some areas are assigned strict legal protection that permits few extractive human uses. Other protected area designations permit a wider range of uses. Whether strictly protected areas are more effective in achieving environmental objectives is an empirical question: although strictly protected areas legally permit less anthropogenic disturbance, the social conflicts associated with assigning strict protection may lead politicians to assign strict protection to less-threatened areas and may lead citizens or enforcement agents to ignore the strict legal restrictions. We contrast the impacts of strictly and less strictly protected areas in four countries using IUCN designations to measure de jure strictness, data on deforestation to measure outcomes, and a quasi-experimental design to estimate impacts. On average, stricter protection reduced deforestation rates more than less strict protection, but the additional impact was not always large and sometimes arose because of where stricter protection was assigned rather than regulatory strictness per se. We also show that, in protected area studies contrasting y management regimes, there are y 2 policy-relevant impacts, rather than only y, as earlier studies have implied. (letter)

    The Dutch parliament has recently accepted a tax law in which certain groups of alternative therapists can be exempt from VAT. To be eligible for this VAT exemption, the disciplines to which the therapists belong have to meet certain training requirements. In this article it is contended, in agreement with the Royal College of Physicians in the UK, that statutory regulation is inappropriate for disciplines whose therapies are neither of proved benefit nor appropriately tested. It legitimizes harmful therapies. This is illustrated by two serious accidents, previously described in this journal, caused by a chiropractor and a craniosacral therapist.

    2014-06-01

    In The Netherlands, hospital care production pressure recently increased substantially, while the number of nurse anesthetists available did not match this rise. The longtime existing norm of no night shifts for nurses beyond the age of 55 years was increased to age 57 to meet the demand for more nurse anesthetists. In this pilot study, we aimed to determine the level of fatigue and its correlation with demographic items among this category of employees. A validated questionnaire was distributed to all Dutch nurse anesthetists above 50 years of age working in Dutch hospitals, which asked for their level of fatigue. The Checklist Individual Strength Questionnaire was used to measure fatigue. Overall, 105 of 115 potential participants completed the questionnaire (response rate, 91%). The mean scores (+/- standard deviation) were as follows: total fatigue, 81.3 +/- 8.3; subjective fatigue, 31.4 +/- 3.2; physical activity, 13.1 +/- 2.2; motivation, 16.8 +/- 2.6; and concentration, 20.0 +/- 3.8. No correlation could be demonstrated between demographic characteristics and fatigue. Dutch nurse anesthetists above the age of 50 years show a high fatigue score and therefore need special attention to prevent them from harmful physical and psychological effects and to sustain maximal patient safety.

    Full Text Available The UNICUM development project, commissioned by the Dutch Academic Heritage Foundation Stichting Academisch Erfgoed (SAE, has been carried out by the five classic Dutch universities in 2010– 2012. UNICUM, short for ‘University Collections and University Museums’, has received a national government grant to create a digital portal to Dutch academic heritage. The portal, which can be reached via www.academischecollecties.nl, presents both academic archives and museum and library collections. Images, collection metadata and items can be found on one site. The UNICUM idea is inspired by the Online Archive of California. The project is important because it crosses the traditional sector boundaries between museums, libraries and archives, it creates awareness of the opportunities which this cross-sectoral approach offers, and it retains the context of – and the relation between – objects within collections as a whole. Moreover, the joint effort brings to light the importance of creating metadata according to international standards to stimulate re-use and exchange of content. In addition, UNICUM intended to be a technical project in which multi-level descriptions are presented and can be browsed in a structured way (collections linked to objects, and archives linked to separate documents. Now the project is finished, the focus will shift to generating content.

  10. A Dutch Confederate: Charles Liernur Defends Slavery in America

    Full Text Available In the 1850s and 1860s, Dutch immigrants in America struggled to square their racial views with the politics of slavery in their new country. The historiography of the Dutch world would benefit from incorporating this story, because it is often in moments of conflict when the most explicit expressions of ideology present themselves. The letters of Charles Liernur, a Dutch-born Confederate, provide a unique insight into the mind of an explicit supporter of slavery in an American context. How and why a Dutchman could defend slavery is the primary question this article addresses. Building on Liernur’s story, this article also challenges the standard view that Dutch Americans were natural opponents of slavery. Instead, they held diverse and ambiguous views, shaped in part by the circumstances of their settlement.Een Nederlandse Confederate: Charles Liernur verdedigt slavernij in AmerikaIn de jaren vijftig en zestig van de negentiende eeuw hadden Nederlandse immigranten in Amerika grote moeite een standpunt in te nemen met betrekking tot de slavernij. Een analyse daarvan lijkt van belang voor de Nederlandse geschiedschrijving, omdat ideologische overtuigingen vaak tijdens conflicten op scherpe wijze uitgedragen worden. De brieven van Charles Liernur, een Nederlandse ‘Confederate’, bieden een unieke blik op de denkwereld van eenuitgesproken voorstander van de slavernij. Hoe en waarom kon een Nederlander zo fel de slavernij verdedigen? Dat is de centrale vraag waarop dit artikel een antwoord probeert te geven. Het verhaal van Liernur laat zien dat de gangbare visie, dat Nederlandse Amerikanen van nature tegenstanders van de slavernij waren, niet klopt. Immigranten hadden veeleer uiteenlopende en ambigue meningen over slavernij, bepaald door de omstandigheden waarmee ze in hun nieuwe vaderland te maken kregen.

    The Netherlands is one of the few countries where euthanasia is legal under strict conditions. This study investigates whether Dutch newspaper articles use the term 'euthanasia' according to the legal definition and determines what arguments for and against euthanasia they contain. We did an electronic search of seven Dutch national newspapers between January 2009 and May 2010 and conducted a content analysis. Of the 284 articles containing the term 'euthanasia', 24% referred to practices outside the scope of the law, mostly relating to the forgoing of life-prolonging treatments and assistance in suicide by others than physicians. Of the articles with euthanasia as the main topic, 36% described euthanasia in the context of a terminally ill patient, 24% for older persons, 16% for persons with dementia, and 9% for persons with a psychiatric disorder. The most frequent arguments for euthanasia included the importance of self-determination and the fact that euthanasia contributes to a good death. The most frequent arguments opposing euthanasia were that suffering should instead be alleviated by better care, that providing euthanasia can be disturbing, and that society should protect the vulnerable. Of the newspaper articles, 24% uses the term 'euthanasia' for practices that are outside the scope of the euthanasia law. Typically, the more unusual cases are discussed. This might lead to misunderstandings between citizens and physicians. Despite the Dutch legalisation of euthanasia, the debate about its acceptability and boundaries is ongoing and both sides of the debate are clearly represented.

  13. A Hybrid P2P Overlay Network for Non-strictly Hierarchically Categorized Content

    Science.gov (United States)

    Wan, Yi; Asaka, Takuya; Takahashi, Tatsuro

    In P2P content distribution systems, there are many cases in which the content can be classified into hierarchically organized categories. In this paper, we propose a hybrid overlay network design suitable for such content called Pastry/NSHCC (Pastry for Non-Strictly Hierarchically Categorized Content). The semantic information of classification hierarchies of the content can be utilized regardless of whether they are in a strict tree structure or not. By doing so, the search scope can be restrained to any granularity, and the number of query messages also decreases while maintaining keyword searching availability. Through simulation, we showed that the proposed method provides better performance and lower overhead than unstructured overlays exploiting the same semantic information.

    We investigated 400 individual fish of four North Sea species: Atlantic Herring, Sprat, Common Dab, and Whiting on ingestion of >20μm microplastic. Strict quality assurance criteria were followed in order to control contamination during the study. Two plastic particles were found in only 1 (a Sprat) out of 400 individuals (0.25%, with a 95% confidence interval of 0.09-1.1%). The particles were identified to consist of polymethylmethacrylate (PMMA) through FTIR spectroscopy. No contamination occurred during the study, showing the method applied to be suitable for microplastic ingestion studies in biota. We discuss the low particle count for North Sea fish with those in other studies and suggest a relation between reported particle count and degree of quality assurance applied. Microplastic ingestion by fish may be less common than thought initially, with low incidence shown in this study, and other studies adhering to strict quality assurance criteria.

    2013-01-01

    Preconditioners based upon sweeps and diffusion-synthetic acceleration have been constructed and applied to the zeroth and first spatial moments of the 1-D S n transport equation using a strictly non negative nonlinear spatial closure. Linear and nonlinear preconditioners have been analyzed. The effectiveness of various combinations of these preconditioners are compared. In one dimension, nonlinear sweep preconditioning is shown to be superior to linear sweep preconditioning, and DSA preconditioning using nonlinear sweeps in conjunction with a linear diffusion equation is found to be essentially equivalent to nonlinear sweeps in conjunction with a nonlinear diffusion equation. The ability to use a linear diffusion equation has important implications for preconditioning the S n equations with a strictly non negative spatial discretization in multiple dimensions. (authors)

    The aim of this study was to enrich, characterize and identify strict anaerobic extreme thermophilic hydrogen (H-2) producers from digested household solid wastes. A strict anaerobic extreme thermophilic H-2 producing bacterial culture was enriched from a lab-scale digester treating household...... wastes at 70 degrees C. The enriched mixed culture consisted of two rod-shaped bacterial members growing at an optimal temperature of 80 degrees C and an optimal pH 8.1. The culture was able to utilize glucose, galactose, mannose, xylose, arabinose, maltose, sucrose, pyruvate and glycerol as carbon...... sources. Growth on glucose produced acetate, H-2 and carbon dioxide. Maximal H-2 production rate on glucose was 1.1 mmol l(-1) h(-1) with a maximum H-2 yield of 1.9 mole H-2 per mole glucose. 16S ribosomal DNA clone library analyses showed that the culture members were phylogenetically affiliated...

    Expressions are derived for an idealized model of a complex electric power system; these expressions define the greatest level of stability of an electric power system and the optimum combination of stabilization factors with automatic excitation control in a single power system. The possibility of increasing the level of stability of an electric power system with simultaneous strict automatic excitation control of the synychronous generators in several power systems is analyzed.

    Full Text Available The process of decomposing p-nitrophenol (PNP with power ultrasound requires strict control of acoustic and electric conditions. In this study, the conditions, including acoustic power and acoustic intensity, but not ultrasonic frequency, were controlled strictly at constant levels. The absorbency and the COD concentrations of the samples were measured in order to show the variation of the sample concentration. The results show significant differences in the trend of the solution degradation rate as acoustic power increases after the PNP solution (with a concentration of 114 mg/L and a pH value of 5.4 is irradiated for 60 min with ultrasonic frequencies of 530.8 kHz, 610.6 kHz, 855.0 kHz, and 1 130.0 kHz. The degradation rate of the solution increases with time and acoustic power (acoustic intensity. On the other hand, the degradation rate of the solution is distinctly dependent on frequency when the acoustic power and intensity are strictly controlled and maintained at constant levels. The degradation rate of the PNP solution declines with ultrasonic frequencies of 530.8 kHz, 610.6 kHz, 855.0 kHz, and 1 130.0 kHz; the COD concentration, on the contrary, increase.

  20. Examination of the PCICE method in the nearly incompressible, as well as strictly incompressible, limits

    Berry, Ray A.; Martineau, Richard C.

    2007-01-01

    The conservative-form, pressure-based PCICE numerical method (Martineau and Berry, 2004) (Berry, 2006), recently developed for computing transient fluid flows of all speeds from very low to very high (with strong shocks), is simplified and generalized. Though the method automatically treats a continuous transition of compressibility, three distinct, limiting compressibility regimes are formally defined for purposes of discussion and comparison with traditional methods - the strictly incompressible limit, the nearly incompressible limit, and the fully compressible limit. The PCICE method's behavior is examined in each limiting regime. In the strictly incompressible limit the PCICE algorithm reduces to the traditional MAC-type method with velocity divergence driving the pressure Poisson equation. In the nearly incompressible limit the PCICE algorithm is found to reduce to a generalization of traditional incompressible methods, i.e. to one in which not only the velocity divergence effect, but also the density gradient effect is included as a driving function in the pressure Poisson equation. This nearly incompressible regime has received little attention, and it appears that in the past, strictly incompressible methods may have been conveniently applied to flows in this regime at the expense of ignoring a potentially important coupling mechanism. This could be significant in many important flows; for example, in natural convection flows resulting from high heat flux. In the fully compressible limit or regime, the algorithm is found to reduce to an expression equivalent to density-based methods for high-speed flow. (author)

    Accurate mass determination of clusters of galaxies is crucial if they are to be used as cosmological probes. However, there are some discrepancies between cluster masses determined based on gravitational lensing and X-ray observations assuming strict hydrostatic equilibrium (i.e., the equilibrium gas pressure is provided entirely by thermal pressure). Cosmological simulations suggest that turbulent gas motions remaining from hierarchical structure formation may provide a significant contribution to the equilibrium pressure in clusters. We analyze a sample of massive clusters of galaxies drawn from high-resolution cosmological simulations and find a significant contribution (20%-45%) from non-thermal pressure near the center of relaxed clusters, and, in accord with previous studies, a minimum contribution at about 0.1 R vir , growing to about 30%-45% at the virial radius, R vir . Our results strongly suggest that relaxed clusters should have significant non-thermal support in their core region. As an example, we test the validity of strict hydrostatic equilibrium in the well-studied massive galaxy cluster A1689 using the latest high-resolution gravitational lensing and X-ray observations. We find a contribution of about 40% from non-thermal pressure within the core region of A1689, suggesting an alternate explanation for the mass discrepancy: the strict hydrostatic equilibrium is not valid in this region.

    2014-06-01

    Full Text Available An improved dutch roll approximation for hypersonic vehicle is presented. From the new approximations, the dutch roll frequency is shown to be a function of the stability axis yaw stability and the dutch roll damping is mainly effected by the roll damping ratio. In additional, an important parameter called roll-to-yaw ratio is obtained to describe the dutch roll mode. Solution shows that large-roll-to-yaw ratio is the generate character of hypersonic vehicle, which results the large error for the practical approximation. Predictions from the literal approximations derived in this paper are compared with actual numerical values for s example hypersonic vehicle, results show the approximations work well and the error is below 10 %.

    Full Text Available Aim: To determine whether the subjective oral health (SOH of the Dutch adult population was associated with clinical and demographic variables. Methods: A clinical examination was conducted in a sample of 1,018 people from the Dutch city of ‘s-Hertogenbosch. SOH was measured using the Dutch translation of the short form of the Oral Health Impact Profile (OHIP-NL14. Results: The average score on the OHIP-NL14 was 2.8 ± 5.9 and 51% of the respondents had a score of 0. Dental status was the most important predictor of SOH. Conclusions:  The SOH in the Dutch adult population was much better than in groups of adults in Australia, the United Kingdom and New Zealand. Nevertheless, there were important variations in SOH related to dental and socio-economic status.

    It has been suggested that the cancer risk of migrants from low-income to high-income countries will converge toward the levels of their host country. However, comparisons with country of origin are mostly lacking. We compared cancer incidence and mortality rates of Surinamese migrants in the Netherlands to both native Dutch and Surinamese levels. Data covering the period 1995-2008 were obtained from Surinamese and Dutch national cancer registries and national cause-of-death registries. Cancer incidence was studied for 21 types of cancer and cancer mortality for nine types. We calculated age-standardized incidence/mortality ratios (SIR/SMR) for the Surinamese migrants and for Suriname, using the native Dutch population as reference. Significantly lower overall cancer incidence (SIR = 0.77, 95% CI = 0.69-0.84) and mortality rates (SMR = 0.63, 95% CI = 0.55-0.72) were found for Surinamese migrants compared to native Dutch. Generally, cancer risk was lower for most cancers (e.g., cancer of the breast, colon and rectum, lung), but higher for other cancers (e.g., cancer of the uterine cervix, liver). For most cancers, cancer risk of the Surinamese migrants was in-between Surinamese and native Dutch levels. Importantly, for many cancers, migrants' incidence and mortality rates had not closely approached native Dutch rates. For skin cancer, incidence levels for Surinamese migrants were lower than both Surinamese and native Dutch levels. The results suggest that cancer incidence and mortality rates of Surinamese migrants generally converge from Surinamese toward Dutch levels, though not for all cancer types. Overall, Surinamese migrants still had a much more favorable cancer profile than the native Dutch population.

    The Dutch-Flemish PROMIS Group translated the adult PROMIS Pain Interference item bank into Dutch-Flemish. The aims of the current study were to calibrate the parameters of these items using an item response theory (IRT) model, to evaluate the cross-cultural validity of the Dutch-Flemish translations compared to the original English items, and to evaluate their reliability and construct validity. The 40 items in the bank were completed by 1085 Dutch chronic pain patients. Before calibrating the items, IRT model assumptions were evaluated using confirmatory factor analysis (CFA). Items were calibrated using the graded response model (GRM), an IRT model appropriate for items with more than two response options. To evaluate cross-cultural validity, differential item functioning (DIF) for language (Dutch vs. English) was examined. Reliability was evaluated based on standard errors and Cronbach's alpha. To evaluate construct validity correlations with scores on legacy instruments (e.g., the Disabilities of the Arm, Shoulder and Hand Questionnaire) were calculated. Unidimensionality of the Dutch-Flemish PROMIS Pain Interference item bank was supported by CFA tests of model fit (CFI = 0.986, TLI = 0.986). Furthermore, the data fit the GRM and showed good coverage across the pain interference continuum (threshold-parameters range: -3.04 to 3.44). The Dutch-Flemish PROMIS Pain Interference item bank has good cross-cultural validity (only two out of 40 items showing DIF), good reliability (Cronbach's alpha = 0.98), and good construct validity (Pearson correlations between 0.62 and 0.75). A computer adaptive test (CAT) and Dutch-Flemish PROMIS short forms of the Dutch-Flemish PROMIS Pain Interference item bank can now be developed.

    The aim of this study is to investigate psychometric properties of the Client Satisfaction Questionnaire (CSQ-8) in a Dutch substance abuse population. The CSQ-8 and the Mental Health Thermometer (the standard Dutch satisfaction instrument) were sent to 927 patients of a Dutch substance abuse treatment centre. (response rate 28.3%; n = 262). Data were compared on several variables (i.e., age, gender, ethnicity, treatment type). For a subgroup of responders (n = 84), data were compared with pre-treatment problem severity and treatment need (the European Addiction Severity Index). Both internal consistency and concurrent validity were found to be high. Only treatment type had significant effects on CSQ-8 satisfaction scores. Scores were negatively skewed. The CSQ-8 is as suitable an instrument to be used in addict populations, as it is in other populations. (c) 2005 S. Karger AG, Basel

    Complementary and alternative medicine (CAM) is subject to heated debates and prejudices. Studies show that CAM is widely used by psychiatric patients, usually without the guidance of a therapist and without the use of a solid working method, leading to potential health risks. The purpose of this study is to facilitate the judicious use of CAM alongside conventional psychiatry in an outpatient psychiatric clinic. A search was made through scientific and legal articles and discussion in focus groups. In the Centre for Integrative Psychiatry (CIP) of Lentis in The Netherlands, some carefully selected CAM are offered under strict conditions, alongside conventional treatments. Because of the controversy and the potential health risks, Lentis designed a protocol that is presented. The CIP hopes, by using this protocol, to better serve and respect the individual needs and preferences of the diversity of psychiatric patients in our Dutch multicultural society, and better protect them from harm.

    There are no Dutch language disease-specific questionnaires for patients with patellofemoral pain syndrome available that could help Dutch physiotherapists to assess and monitor these symptoms and functional limitations. The aim of this study was to translate the original disease-specific Kujala Patellofemoral Score into Dutch and evaluate its reliability. The questionnaire was translated from English into Dutch in accordance with internationally recommended guidelines. Reliability was determined in 50 stable subjects with an interval of 1 week. The patient inclusion criteria were age between 14 and 60 years; knowledge of the Dutch language; and the presence of at least three of the following symptoms: pain while taking the stairs, pain when squatting, pain when running, pain when cycling, pain when sitting with knees flexed for a prolonged period, grinding of the patella and a positive clinical patella test. The internal consistency, test-retest reliability, measurement error and limits of agreement were calculated. Internal consistency was 0.78 for the first assessment and 0.80 for the second assessment. The intraclass correlation coefficient (ICC agreement ) between the first and second assessments was 0.98. The mean difference between the first and second measurements was 0.64, and standard deviation was 5.51. The standard error measurement was 3.9, and the smallest detectable change was 11. The Bland and Altman plot shows that the limits of agreement are -10.37 and 11.65. The results of the present study indicated that the test-retest reliability translated Dutch version of the Kujala Patellofemoral Score questionnaire is equivalent of the test-retest original English language version and has good internal consistency.

    Full Text Available Active quantum error correction on topological codes is one of the most promising routes to long-term qubit storage. In view of future applications, the scalability of the used decoding algorithms in physical implementations is crucial. In this work, we focus on the one-dimensional Majorana chain and construct a strictly local decoder based on a self-dual cellular automaton. We study numerically and analytically its performance and exploit these results to contrive a scalable decoder with exponentially growing decoherence times in the presence of noise. Our results pave the way for scalable and modular designs of actively corrected one-dimensional topological quantum memories.

Single molecules, quantum dots or defect centres in crystals should be used as light source. “Single photon detectors” do not meet their promise―only “photon number resolving single photon detectors” do so. Particularly, the accumulation time argument, the only safe basis for the postulate of a strictly particle like photon, has so far not yet been verified.

    Full Text Available This article concerns the wave interaction problem for a strictly hyperbolic system of conservation laws whose Riemann solutions involve delta shock waves. To cover all situations, the global solutions are constructed when the initial data are taken as three piecewise constant states. It is shown that the Riemann solutions are stable with respect to a specific small perturbation of the Riemann initial data. In addition, some interesting nonlinear phenomena are captured during the process of constructing the solutions, such as the generation and decomposition of delta shock waves.

    This study took place within the framework of a general update of the average radiation dose for the Dutch population. It focuses on consumer products in which radionuclides have been intentionally incorporated and on radiation-emitting devices that can be supplied to members of the public without special surveillance. Eleven consumer products were studied in more detail. The radiation from these products determined 90% of the total collective dose due to consumer products in the Netherlands in 1988. Individual and collective doses are presented here for each product. The total collective dose has decreased from 130 personSv in 1988 to 4.6 personSv at present. This reduction was attributed to: a decrease in the number of radioactive products (gas mantles), lower estimates of the number of radioactive products present in the Netherlands thanks to new information (camera lenses, smoke detectors containing Ra-226), replacement of radioactive by non-radioactive products (gas mantles, dental protheses), and a lowe...

    This Dutch Roadmap Biorefinery forms the framework and knowledge basis for Research, Development and Demonstration (RD and D) activities, covering both technical and non-technical issues, necessary to develop biorefinery-based value chains to such an extend that large-scale market implementation as part of the future Bio-based Economy will become a reality. The Roadmap describes the broad landscape of biorefinery options in The Netherlands. The descriptions of possible initiatives within the so called Moonshots (general biorefinery strategies containing more specific biorefinery-based value chains that will become fully operational at industrial scale in the short and midterm to facilitate the transition to a Bio-based Economy in the longer-term) deliberately do not contain the names of parties that might be involved. However, many of the current initiatives have been described in another document, the 'Status Report Biorefinery 2007'. Also the exact economics of possible initiatives have not been specified yet. These will become clearer when proposals will be submitted by consortia of the stakeholders involved.

    Bed rest and physical inactivity are the consequences of hospital admission for many patients. Physical inactivity induces changes in glucose metabolism, but its effect on the incretin effect, which is reduced in, e.g., Type 2 diabetes, is unknown. To investigate how 8 days of strict bed rest affects the incretin effect, 10 healthy nonobese male volunteers underwent 8 days of strict bed rest. Before and after the intervention, all volunteers underwent an oral glucose tolerance test (OGTT) followed by an intravenous glucose infusion (IVGI) on the following day to mimic the blood glucose profile from the OGTT. Blood glucose, serum insulin, serum C-peptide, plasma incretin hormones [glucagon-like peptide (GLP-1) and glucose-dependent insulinotropic peptide (GIP)], and serum glucagon were measured serially during both the OGTT and the IVGI. The incretin effect is calculated as the relative difference between the area under the curve for the insulin response during the OGTT and that of the corresponding IVGI, respectively. Concentrations of glucose, insulin, C-peptide, and GIP measured during the OGTT were higher after the bed rest intervention (all P effect (P = 0.6). In conclusion, 8 days of bed rest induces insulin resistance, but we did not see evidence of an associated change in the incretin effect. Copyright © 2016 the American Physiological Society.

    Despite a tremendous interest on molybdenum disulfide as a thinnest direct band gap semiconductor, single step synthesis of a large area purely monolayer MoS 2 film has not yet been reported. Here, we report a CVD route to synthesize a continuous film of strictly monolayer MoS 2 covering an area as large as a few cm 2 on a variety of different substrates without using any seeding material or any elaborate pretreatment of the substrate. This is achieved by allowing the growth to take place in the naturally formed gap between a piece of SiO 2 coated Si wafer and the substrate, when the latter is placed on top of the former inside a CVD reactor. We propose a qualitative model to explain why the MoS 2 films are always strictly monolayer in this method. The photoluminescence study of these monolayers shows the characteristic excitonic and trionic features associated with monolayer MoS 2 . In addition, a broad defect related luminescence band appears at ∼1.7 eV. As temperature decreases, the intensity of this broad feature increases, while the band edge luminescence reduces

    Full Text Available The mitochondrial cytochrome c-oxidase subunit I (COI can serve as a fast and accurate marker for the identification of animal species, and has been applied in a number of studies on birds. We here sequenced the COI gene for 387 individuals of 147 species of birds from the Netherlands, with 83 species being represented by >2 sequences. The Netherlands occupies a small geographic area and 95% of all samples were collected within a 50 km radius from one another. The intraspecific divergences averaged 0.29% among this assemblage, but most values were lower; the interspecific divergences averaged 9.54%. In all, 95% of species were represented by a unique barcode, with 6 species of gulls and skua (Larus and Stercorariusat least one shared barcode. This is best explained by these species representing recent radiations with ongoing hybridization. In contrast, one species, the Lesser Whitethroat Sylvia curruca showed deep divergences, averaging 5.76% and up to 8.68% between individuals. These possibly represent two distinct taxa, S. curruca and S. blythi, both clearly separated in a haplotype network analysis. Our study adds to a growing body of DNA barcodes that have become available for birds, and shows that a DNA barcoding approach enables to identify known Dutch bird species with a very high resolution. In addition some species were flagged up for further detailed taxonomic investigation, illustrating that even in ornithologically well-known areas such as the Netherlands, more is to be learned about the birds that are present.

    We studied mainstream couples in The Netherlands and Turkey as well as Turkish-Dutch immigrant couples to address cultural factors associated with marital satisfaction. A total of 13 Turkish (mainstream couples living in Turkey), 19 Turkish-Dutch (Turkish immigrant couples living in The Netherlands), and 17 Dutch (mainstream couples living in The Netherlands) married dyads (total of 98 individuals) were independently interviewed about positive and negative characteristics of marriages, determinants of general marital satisfaction and dissatisfaction, spousal communication, marital conflict, and marital roles. Multivariate tests revealed ethnic group differences on all marriage-related domains except the conflict resolution strategies. However, univariate analyses showed differences in few themes within domains; main differences were assessed between the Turkish/Turkish-Dutch (who put more emphasis on children and economical aspects) and Dutch couples (who put more emphasis on behavior, and personality of the spouse, reciprocity, emotional sharing, and psychological roles). Turkish-Dutch couples were more similar to Turkish than to Dutch couples. Results were discussed in light of the socioeconomic development and cultural value theories, which are believed to provide a useful framework for understanding the role of culture in marital satisfaction.

    With respect to pedophilia and the age of consent, the Netherlands warrants special attention. Although pedophilia is not as widely accepted in the Netherlands as sometimes is supposed, developments in the judicial practice showed a growing reservedness. These developments are a spin-off of related developments in Dutch society. The tolerance in the Dutch society has roots that go far back in history and is also a consequence of the way this society is structured. The social changes of the sixties and seventies resulted in a "tolerance at arm's length" for pedophiles, which proved to be deceptive when the Dutch government proposed to lower the age of consent in 1985. It resulted in a vehement public outcry. The prevailing sex laws have been the prime target of protagonists of pedophile emancipation. Around 1960, organized as a group, they started to undertake several activities. In the course of their existence, they came to redefine the issue of pedophilia as one of youth emancipation.

    A popular belief is that alcohol improves the ability to speak in a foreign language. The effect of acute alcohol consumption on perceived foreign language performance and actual foreign language performance in foreign language learners has not been investigated. The aim of the current study was to test the effects of acute alcohol consumption on self-rated and observer-rated verbal foreign language performance in participants who have recently learned this language. Fifty native German speakers who had recently learned Dutch were randomized to receive either a low dose of alcohol or a control beverage that contained no alcohol. Following the experimental manipulation, participants took part in a standardized discussion in Dutch with a blinded experimenter. The discussion was audio-recorded and foreign language skills were subsequently rated by two native Dutch speakers who were blind to the experimental condition (observer-rating). Participants also rated their own individual Dutch language skills during the discussion (self-rating). Participants who consumed alcohol had significantly better observer-ratings for their Dutch language, specifically better pronunciation, compared with those who did not consume alcohol. However, alcohol had no effect on self-ratings of Dutch language skills. Acute alcohol consumption may have beneficial effects on the pronunciation of a foreign language in people who have recently learned that language.

  16. Disordered strictly jammed binary sphere packings attain an anomalously large range of densities

    2013-08-01

    Previous attempts to simulate disordered binary sphere packings have been limited in producing mechanically stable, isostatic packings across a broad spectrum of packing fractions. Here we report that disordered strictly jammed binary packings (packings that remain mechanically stable under general shear deformations and compressions) can be produced with an anomalously large range of average packing fractions 0.634≤ϕ≤0.829 for small to large sphere radius ratios α restricted to α≥0.100. Surprisingly, this range of average packing fractions is obtained for packings containing a subset of spheres (called the backbone) that are exactly strictly jammed, exactly isostatic, and also generated from random initial conditions. Additionally, the average packing fractions of these packings at certain α and small sphere relative number concentrations x approach those of the corresponding densest known ordered packings. These findings suggest for entropic reasons that these high-density disordered packings should be good glass formers and that they may be easy to prepare experimentally. We also identify an unusual feature of the packing fraction of jammed backbones (packings with rattlers excluded). The backbone packing fraction is about 0.624 over the majority of the α-x plane, even when large numbers of small spheres are present in the backbone. Over the (relatively small) area of the α-x plane where the backbone is not roughly constant, we find that backbone packing fractions range from about 0.606 to 0.829, with the volume of rattler spheres comprising between 1.6% and 26.9% of total sphere volume. To generate isostatic strictly jammed packings, we use an implementation of the Torquato-Jiao sequential linear programming algorithm [Phys. Rev. EPLEEE81539-375510.1103/PhysRevE.82.061302 82, 061302 (2010)], which is an efficient producer of inherent structures (mechanically stable configurations at the local maxima in the density landscape).

    Full Text Available With the rapid economic growth and development, the problem of environmental pollution in China’s cities is becoming increasingly serious, and environmental pollution takes on a regional difference. There is, however, little comprehensive evaluation on the environmental performance and the regional difference of strictly-environmental-monitored cities in China. In this paper, the environmental performance of 109 strictly-environmental-monitored cities in China is evaluated in terms of natural performance, management performance, and scale performance by Data Envelopment Analysis (DEA, incorporating PM2.5 and PM10 as undesirable outputs. The empirical results show that: (1 At present, the natural performance is quite high, while the management performance is noticeably low for most cities. (2 The gap between the level of economic development and environmental protection among cities in China is large, and the scale efficiency of big cities is better than that of smaller cities. The efficiency value of large-scale cities such as Beijing, Shanghai, Guangzhou, Shenzhen, etc. is high, equaling 1; the value of smaller cities such as Sanmenxia, Baoding, Mudanjiang, and Pingdingshan is low, close to 0, indicating that big cities are characterized by high environmental efficiency. (3 From the perspective of region, the level of environmental performance in China is very uneven. For example, the environmental efficiency level of the Pan-Pearl River Delta region is superior to that of the Pan-Yangtze River region and the Bahia Rim region, whose values of environmental efficiency are 0.858, 0.658, and 0.622 respectively. The average efficiency of the Southern Coastal Economic Zone, Eastern Coastal Comprehensive Economic Zone, and the Comprehensive Economic Zone in the middle reaches of the Yangtze River is higher than that of other regions. Finally, corresponding countermeasures and suggestions are put forward. The method used in this paper is applicable

    To establish the reliability and validity of the Dutch version of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) in women with pelvic floor dysfunction. The PISQ-12 was translated into Dutch following a standardized translation process. A group of 124 women involved in a heterosexual relationship who had had symptoms of urinary incontinence, fecal incontinence and/or pelvic organ prolapse for at least 3 months were eligible for inclusion. A reference group was used for assessment of discriminative ability. Data were analyzed for internal consistency, reproducibility, construct validity, responsiveness, and interpretability. An alteration was made to item 12 and was corrected for during the analysis. The patient group comprised 70 of the 124 eligible women, and the reference group comprised 208 women from a panel representative of the Dutch female population. The Dutch PISQ-12 showed an adequate internal consistency with a Cronbach's alpha of 0.57 - 0.69, increasing with correction for item 12 to 0.69 - 0.75, for the reference and patient group, respectively. Scores in the patient group were lower (32.6 ± 6.9) than in the reference group (36.3 ± 4.8; p = 0.0001), indicating a lower sexual function in the patient group and good discriminative ability. Reproducibility was excellent with an intraclass correlation coefficient for agreement of 0.93 (0.88 - 0.96). A positive correlation was found with the Short Form-12 Health Survey (SF-12) measure representing good criterion validity. Due to the small number of patients who had received treatment at the 6-month follow-up, no significant responsiveness could be established. This study showed that the Dutch version of the PISQ-12 has good validity and reliability. The PISQ-12 will enable Dutch physicians to evaluate sexual dysfunction in women with pelvic floor disorders.

    Tebani, K.; Amari, S.; Kara, R.

    2018-04-01

    In this paper, we treat the control problem of timed discrete event systems under temporal constraints. This type of constraint is very frequent in production systems, transportation network and in networked automation systems. Precisely, we are interested in the validation of strict temporal constraints imposed on the paths in a timed event graph (TEG) by using Max-Plus algebra. Not all the transitions of the considered TEG model are controllable, i.e. only the input transitions are controllable. An analytical approach for computing state feedback controllers is developed. Sufficient condition is given for the existence of causal control laws satisfying the temporal constraints. In the first, a TEG with observable transitions is considered. Then, the proposed approach is extended to the partially observable TEG. The synthesised feedback can be interpreted by places of control connected to the TEG to guarantee the respect of the time constraints. The proposed method is illustrated in the assembly system example.

    2018-06-01

    This paper proposes a novel data-driven control approach to address the problem of adaptive optimal tracking for a class of nonlinear systems taking the strict-feedback form. Adaptive dynamic programming (ADP) and nonlinear output regulation theories are integrated for the first time to compute an adaptive near-optimal tracker without any a priori knowledge of the system dynamics. Fundamentally different from adaptive optimal stabilization problems, the solution to a Hamilton-Jacobi-Bellman (HJB) equation, not necessarily a positive definite function, cannot be approximated through the existing iterative methods. This paper proposes a novel policy iteration technique for solving positive semidefinite HJB equations with rigorous convergence analysis. A two-phase data-driven learning method is developed and implemented online by ADP. The efficacy of the proposed adaptive optimal tracking control methodology is demonstrated via a Van der Pol oscillator with time-varying exogenous signals.

  10. Lyme Neuroborreliosis: Preliminary Results from an Urban Referral Center Employing Strict CDC Criteria for Case Selection

    Directory of Open Access Journals (Sweden)

    David S. Younger

    2010-01-01

    Full Text Available Lyme neuroborreliosis or “neurological Lyme disease” was evidenced in 2 of 23 patients submitted to strict criteria for case selection of the Centers for Disease Control and Prevention employing a two-tier test to detect antibodies to Borrelia burgdorferi at a single institution. One patient had symptomatic polyradiculoneuritis, dysautonomia, and serological evidence of early infection; and another had symptomatic small fiber sensory neuropathy, distal polyneuropathy, dysautonomia, and serological evidence of late infection. In the remaining patients symptoms initially ascribed to Lyme disease were probably unrelated to B. burgdorferi infection. Our findings suggest early susceptibility and protracted involvement of the nervous system most likely due to the immunological effects of B. burgdorferi infection, although the exact mechanisms remain uncertain.

  11. A Total Variation Model Based on the Strictly Convex Modification for Image Denoising

    Directory of Open Access Journals (Sweden)

    Boying Wu

    2014-01-01

    Full Text Available We propose a strictly convex functional in which the regular term consists of the total variation term and an adaptive logarithm based convex modification term. We prove the existence and uniqueness of the minimizer for the proposed variational problem. The existence, uniqueness, and long-time behavior of the solution of the associated evolution system is also established. Finally, we present experimental results to illustrate the effectiveness of the model in noise reduction, and a comparison is made in relation to the more classical methods of the traditional total variation (TV, the Perona-Malik (PM, and the more recent D-α-PM method. Additional distinction from the other methods is that the parameters, for manual manipulation, in the proposed algorithm are reduced to basically only one.

  12. Weight of fitness deviation governs strict physical chaos in replicator dynamics

    2018-03-01

    Replicator equation—a paradigm equation in evolutionary game dynamics—mathematizes the frequency dependent selection of competing strategies vying to enhance their fitness (quantified by the average payoffs) with respect to the average fitnesses of the evolving population under consideration. In this paper, we deal with two discrete versions of the replicator equation employed to study evolution in a population where any two players' interaction is modelled by a two-strategy symmetric normal-form game. There are twelve distinct classes of such games, each typified by a particular ordinal relationship among the elements of the corresponding payoff matrix. Here, we find the sufficient conditions for the existence of asymptotic solutions of the replicator equations such that the solutions—fixed points, periodic orbits, and chaotic trajectories—are all strictly physical, meaning that the frequency of any strategy lies inside the closed interval zero to one at all times. Thus, we elaborate on which of the twelve types of games are capable of showing meaningful physical solutions and for which of the two types of replicator equation. Subsequently, we introduce the concept of the weight of fitness deviation that is the scaling factor in a positive affine transformation connecting two payoff matrices such that the corresponding one-shot games have exactly same Nash equilibria and evolutionary stable states. The weight also quantifies how much the excess of fitness of a strategy over the average fitness of the population affects the per capita change in the frequency of the strategy. Intriguingly, the weight's variation is capable of making the Nash equilibria and the evolutionary stable states, useless by introducing strict physical chaos in the replicator dynamics based on the normal-form game.

  13. Strict Liability Versus Policy and Regulation for Environmental Protection and Agricultural Waste Management in Malaysia

    Directory of Open Access Journals (Sweden)

    Mohd Bakri Ishak

    2010-01-01

    Full Text Available Basically, strict liability is part of the mechanism for expressing judgment or sentence by using direct evidence. This principle is very useful in order to obtain remedies from any damage either directly or indirectly. The principle in Rylands v Fletcher is responsible on imposing strict liability where if something brought onto land or collected there escapes liability under this rule can include not only the owner of land but also those who control or occupation on it. However, as a matter of fact, policy and regulation are also important in taking any action against any party who are responsible for environmental pollution or damage, which may include mismanagement of waste or industrial waste or agricultural waste. There are certain policies and regulations on environmental protection such as the National Environmental Policy, certain Acts and several regulations under the Environmental Quality Act 1974 (Act 127, which are very useful for agricultural waste management inter alia: Waters Act 1920 (Act 418, Environmental Quality (Prescribed Premises (Crude Palm Oil Regulations 1977, Environmental Quality (Prescribed Premises (Raw Natural Rubber Regulations 1978, Environmental Quality (Sewage and Industrial Effluents Regulations 1979, and Environmental Quality (Compounding of Offences Rules 1978. As a matter of fact, we should realize that time is of an essence for any parties which are involved in court cases and especially in avoiding the element of externality, which is commonly suffered by the government. In making this paper, therefore, some element of comparison with certain developed jurisdiction such as in the United Kingdom and Japan could not be avoided in order to obtain better outcome and to be more practical for the purpose of environmental protection and agricultural waste management.

    Two bacterial strains were isolated from methanogenic butyrate-oxidizing mixed cultures. The cells were straight to slightly curved, gram-positive rods that were motile by means of multiple flagella and formed endospores. Growth was observed in the temperature range 15-45 degrees C (optimum 37 degrees C) and pH range 5.5-9.0 (optimum pH 7.5). The novel isolates were strictly anaerobic chemo-organotrophs capable of utilizing yeast extract, peptone, tryptone and a variety of sugars and organic acids, but not glucose. None of the accessory electron acceptors tested (elemental sulfur, thiosulfate or fumarate) improved growth, except crotonate, which was dismutated to butyrate and acetate. The G + C content of the DNA of one of the isolates, strain B11-2T, was 30.6 mol%. Phylogenetic analysis based on 16S rDNA sequence similarity between strain B11-2T and some other strictly anaerobic, spore-forming bacteria indicated that the novel isolates represented a species in cluster XI within the low-GC gram-positive bacteria, being most closely related to Alkaliphilus transvaalensis JCM 10712T. DNA-DNA relatedness between strain B11-2T and A. transvaalensis JCM 10712T was 21%. On the basis of physiological and molecular properties, and cellular fatty acid and cell wall compositions, the novel isolates are proposed to represent a novel species of the genus Alkaliphilus, for which the name Alkaliphilus crotonatoxidans is proposed (type strain B11-2T=AS 1.2897T=JCM 11672T).

  16. Wind energy research activities of the Dutch Electricity Generating Board

    International Nuclear Information System (INIS)

    Halberg, N.

    1990-01-01

    The varying degrees of penetration of wind energy conversion systems (WECs) into the Dutch electricity generating system has been examined. A simulation has been carried out using wind data recorded at 6 sites spread across the area of interest in the Netherlands. The recorded wind data has been used in conjunction with a production costing model normally used by Sep (the Dutch Electricity Generating Board) for planning purposes. This model was modified to give a correct assessment of the quantity and value of fuel savings made by WECs. System studies were carried out for the year 2000 for zero wind penetration and for three distinctive penetration degrees of WECs, namely 5%, 10% and 15%. After incorporation of the WECS capacity, adjustments were made to the basic plant mix to allow the capacity credit WECs. Separate production cost simulations were executed for each distinct WECS capacity factor. Economic assessments were carried out using standard procedures. Except for the unpredictable development of fuel prices, the capital costs of the WECs proved to be the determinant for the economic viability of wind power. Significant improvements in costs and performance, as may be achieved through additional technological advances, are needed to made wind power competitive in widespread utility applications.

    1998-04-01

    The Netherlands are the first European gas producer and exporter. The author proposes an analysis of the gas policy of this country. He first recalls some elements of context: peculiarities of energy as a domain of public policy, and characteristics of the Dutch political system. He recalls the historical development of the Dutch gas industry from the 1960's: political economics of natural gas and of competing fuels, development of the Groningen site as the keystone of the Dutch gas policy, and regulation of the industrial sector. In the next part, the author comments the emergence of energy as a topic of public debate from 1995, and how the Dutch gas policy has been put into question again: actors and interaction dynamics, stakes, present policy and perspectives

  12. News media coverage of euthanasia: a content analysis of Dutch national newspapers

    Science.gov (United States)

    2013-01-01

    Background The Netherlands is one of the few countries where euthanasia is legal under strict conditions. This study investigates whether Dutch newspaper articles use the term ‘euthanasia’ according to the legal definition and determines what arguments for and against euthanasia they contain. Methods We did an electronic search of seven Dutch national newspapers between January 2009 and May 2010 and conducted a content analysis. Results Of the 284 articles containing the term ‘euthanasia’, 24% referred to practices outside the scope of the law, mostly relating to the forgoing of life-prolonging treatments and assistance in suicide by others than physicians. Of the articles with euthanasia as the main topic, 36% described euthanasia in the context of a terminally ill patient, 24% for older persons, 16% for persons with dementia, and 9% for persons with a psychiatric disorder. The most frequent arguments for euthanasia included the importance of self-determination and the fact that euthanasia contributes to a good death. The most frequent arguments opposing euthanasia were that suffering should instead be alleviated by better care, that providing euthanasia can be disturbing, and that society should protect the vulnerable. Conclusions Of the newspaper articles, 24% uses the term ‘euthanasia’ for practices that are outside the scope of the euthanasia law. Typically, the more unusual cases are discussed. This might lead to misunderstandings between citizens and physicians. Despite the Dutch legalisation of euthanasia, the debate about its acceptability and boundaries is ongoing and both sides of the debate are clearly represented. PMID:23497284

    Palliative sedation is considered a normal medical practice by the Royal Dutch Medical Association. Therefore, consultation of an expert is not considered mandatory. The European Association of Palliative Care (EAPC) framework for palliative sedation, however, is more stringent: it considers the use of palliative sedation without consulting an expert as injudicious and insists on input from a multi-professional palliative care team. This study investigates the considerations of Dutch physicians concerning consultation about palliative sedation with specialist palliative care services. Fifty-four physicians were interviewed on their most recent case of palliative sedation. Reasons to consult were a lack of expertise and the view that consultation was generally supportive. Reasons not to consult were sufficient expertise, the view that palliative sedation is a normal medical procedure, time pressure, fear of disagreement with the service and regarding consultation as having little added value. Arguments in favour of mandatory consultation were that many physicians lack expertise and that palliative sedation is an exceptional intervention. Arguments against mandatory consultation were practical obstacles that may preclude fulfilling such an obligation (i.e. lack of time), palliative sedation being a standard medical procedure, corroding a physician's responsibility and deterring physicians from applying palliative sedation. Consultation about palliative sedation with specialist palliative care services is regarded as supportive and helpful when physicians lack expertise. However, Dutch physicians have both practical and theoretical objections against mandatory consultation. Based on the findings in this study, there seems to be little support among Dutch physicians for the EAPC recommendations on obligatory consultation.

    The natural diet of felids contains highly digestible animal tissues but also fractions resistant to small intestinal digestion, which enter the large intestine where they may be fermented by the resident microbial population. Little information exists on the microbial degradability of animal tissues in the large intestine of felids consuming a natural diet. This study aimed to rank animal substrates in their microbial degradability by means of an in vitro study using captive cheetahs fed a strict carnivorous diet as fecal donors. Fresh cheetah fecal samples were collected, pooled, and incubated with various raw animal substrates (chicken cartilage, collagen, glucosamine-chondroitin, glucosamine, rabbit bone, rabbit hair, and rabbit skin; 4 replicates per substrate) for cumulative gas production measurement in a batch culture technique. Negative (cellulose) and positive (casein and fructo-oligosaccharides; FOS) controls were incorporated in the study. Additionally, after 72 h of incubation, short-chain fatty acids (SCFA), including branched-chain fatty acids (BCFA), and ammonia concentrations were determined for each substrate. Glucosamine and glucosamine-chondroitin yielded the greatest organic matter cumulative gas volume (OMCV) among animal substrates (P carnivore, and indicates that animal tissues have potentially similar functions as soluble or insoluble plant fibers in vitro. Further research is warranted to assess the impact of fermentation of each type of animal tissue on gastro-intestinal function and health in the cheetah and other felid species.

  15. Hunting the ghosts of a 'strictly quantum field': the Klein-Gordon equation

    This paper aims to identify and tackle some problems related to teaching quantum field theory (QFT) at university level. In particular, problems arising from the canonical quantization are addressed by focusing on the Klein-Gordon equation (KGE). After a brief description of the status of the KGE in teaching as it emerges from an analysis of a selected sample of university textbooks, an analysis of the applications of the KGE in contexts different from the QFT is presented. The results of the analysis show that, while in the real case the solutions of the equation can be easily interpreted from a physical point of view, in the complex case the coherence with relativistic quantum mechanics and the electrodynamics framework brings to light interpretative problems related to the classical complex KG field. The comparison between the classical cases investigated and the QFT framework, where the equation finds a coherent particle interpretation, leads to share Ryder's statement asserting that the KG field is a 'strictly quantum field'. Implications of the results in terms of remarks about the canonical procedure currently utilized for teaching are underlined.

    The effects of a strict uncooked vegan diet on serum lipid and sterol concentrations were studied in patients with rheumatoid arthritis. The subjects were randomized into a vegan diet group (n 16), who consumed a vegan diet for 2-3 months, or into a control group (n 13), who continued their usual omnivorous diets. Serum total and LDL-cholesterol and -phospholipid concentrations were significantly decreased by the vegan diet. The levels of serum cholestanol and lathosterol also decreased, but serum cholestanol:total cholesterol and lathosterol:total cholesterol did not change. The effect of a vegan diet on serum plant sterols was divergent as the concentration of campesterol decreased while that of sitosterol increased. This effect resulted in a significantly greater sitosterol:campesterol value in the vegan diet group than in the control group (1.48 (SD 0.39) v. 0.72 (SD 0.14); P vegan diet changes the relative absorption rates of these sterols and/or their biliary clearance.

    Transposable elements (TEs) are DNA sequences that are able to replicate and move within and between host genomes. Their mechanism of replication is also shared with endogenous retroviruses (ERVs), which are also a type of TE that represent an ancient retroviral infection within animal genomes. Two models have been proposed to explain TE proliferation in host genomes: the strict master model (SMM), and the random template (or transposon) model (TM). In SMM only a single copy of a given TE lineage is able to replicate, and all other genomic copies of TEs are derived from that master copy. In TM, any element of a given family is able to replicate in the host genome. In this paper, we simulated ERV phylogenetic trees under variations of SMM and TM. To test whether current phylogenetic programs can recover the simulated ERV phylogenies, DNA sequence alignments were simulated and maximum likelihood trees were reconstructed and compared to the simulated phylogenies. Results indicate that visual inspection of phylogenetic trees alone can be misleading. However, if a set of statistical summaries is calculated, we are able to distinguish between models with high accuracy by using a data mining algorithm that we introduce here. We also demonstrate the use of our data mining algorithm with empirical data for the porcine endogenous retrovirus (PERV), an ERV that is able to replicate in human and pig cells in vitro.

    No study has previously analyzed pressure pain sensitivity of nerve trunks in migraine. This study aimed to examine the differences in mechanical pain sensitivity over specific nerves between patients with unilateral migraine and healthy controls. Blinded investigators assessed pressure pain thresholds (PPT) over the supra-orbital nerves (V1) and peripheral nerve trunks of both upper extremities (median, radial, and ulnar nerves) in 20 patients with strictly unilateral migraine and 20 healthy matched controls. Pain intensity after palpation over both supra-orbital nerves was also assessed. A pressure algometer was used to quantify PPT, whereas a 10-point numerical pain rate scale was used to evaluate pain to palpation over the supra-orbital nerve. The analysis of covariance revealed that pain to palpation over the supra-orbital nerve was significantly higher (P0.6). In patients with unilateral migraine, we found increased mechano-sensitivity of the supra-orbital nerve on the symptomatic side of the head. Outside the head, the same patients showed increased mechano-sensitivity of the main peripheral nerves of both upper limbs, without asymmetries. Such diffuse hypersensitivity of the peripheral nerves lends further evidence to the presence of a state of hyperexcitability of the central nervous system in patients with unilateral migraine.

    DNA remodelling during endoreplication appears to be a strong developmental characteristic in orchids. In this study, we analysed DNA content and nuclei in 41 species of orchids to further map the genome evolution in this plant family. We demonstrate that the DNA remodelling observed in 36 out of 41 orchids studied corresponds to strict partial endoreplication. Such process is developmentally regulated in each wild species studied. Cytometry data analyses allowed us to propose a model where nuclear states 2C, 4E, 8E, etc. form a series comprising a fixed proportion, the euploid genome 2C, plus 2 to 32 additional copies of a complementary part of the genome. The fixed proportion ranged from 89% of the genome in Vanilla mexicana down to 19% in V. pompona, the lowest value for all 148 orchids reported. Insterspecific hybridisation did not suppress this phenomenon. Interestingly, this process was not observed in mass-produced epiphytes. Nucleolar volumes grow with the number of endocopies present, coherent with high transcription activity in endoreplicated nuclei. Our analyses suggest species-specific chromatin rearrangement. Towards understanding endoreplication, V. planifolia constitutes a tractable system for isolating the genomic sequences that confer an advantage via endoreplication from those that apparently suffice at diploid level. © The Author(s) 2017.

    Dietary intake data of 43 Finnish rheumatoid arthritis patients were collected using 7-day food records. The subjects were randomized into a control and a vegan diet groups, consisting of 22 and 21 subjects, respectively. The subjects in the vegan diet group received an uncooked vegan diet ('living food') for 3 months, and they were tutored daily by a living-food expert. The subjects in the control group continued their usual diets and received no tutoring. Adherence to the strict vegan diet was assessed on the basis of urinary sodium excretion and by the information on consumption of specific food items (wheatgrass juice and the rejuvelac drink). The use of these drinks was variable, and some boiled vegetables were consumed occasionally. However, only one of the subjects in the vegan diet group lacked a clear decrease in urinary sodium excretion. Rheumatoid patients had lower than recommended intakes of iron, zinc and niacin, and their energy intake was low compared to mean daily energy intake of the healthy Finnish females of the same age. Shifting to the uncooked vegan diet significantly increased the intakes of energy and many nutrients. In spite of the increased energy intake, the group on the vegan diet lost 9% of their body weight during the intervention period, indicating a low availability of energy from the vegan diet.

  1. A strictly monofunctional bacterial hydroxymethylpyrimidine phosphate kinase precludes damaging errors in thiamin biosynthesis.

    The canonical kinase (ThiD) that converts the thiamin biosynthesis intermediate hydroxymethylpyrimidine (HMP) monophosphate to the diphosphate can also very efficiently convert free HMP to the monophosphate in prokaryotes, plants, and fungi. This HMP kinase activity enables salvage of HMP, but it is not substrate-specific and so allows toxic HMP analogs and damage products to infiltrate the thiamin biosynthesis pathway. Comparative analysis of bacterial genomes uncovered a gene, thiD2 , that is often fused to the thiamin synthesis gene thiE and could potentially encode a replacement for ThiD. Standalone ThiD2 proteins and ThiD2 fusion domains are small (~130-residues) and do not belong to any previously known protein family. Genetic and biochemical analyses showed that representative standalone and fused ThiD2 proteins catalyze phosphorylation of HMP monophosphate, but not of HMP or its toxic analogs and damage products such as bacimethrin and 5-(hydroxymethyl)-2-methylpyrimidin-4-ol. As strictly monofunctional HMP monophosphate kinases, ThiD2 proteins eliminate a potentially fatal vulnerability of canonical ThiD, at the cost of the ability to reclaim HMP formed by thiamin turnover. ©2017 The Author(s).

    Selectivity index (SI) and lateralization index (LI) thresholds determine the adequacy of adrenal vein sampling (AVS) and the degree of lateralization. The purpose of this study was investigate the clinical outcome of patients whose adrenal vein sampling was interpreted using "strict criteria" (SC) (SIpre-stimuli≥3, SIpost-stimuli≥5 and LIpre-stimuli≥4, LIpost-stimuli≥4). A retrospective review of 73 consecutive AVS procedures was performed and 67 were technically successful. Forty-three patients showed lateralization and underwent surgery, while 24 did not lateralize and were managed conservatively. Systolic blood pressure (SBP), diastolic blood pressure (DBP), kalemia (K(+)), and the change in number of blood pressure (BP) medications were recorded for each patient before and after AVS and potential surgery were performed. In the surgery group, BP and K(+) changed respectively from 160±5.3/100±2.0 mmHg to 127±3.3/80±1.9 (p blood pressure medications were six (14.0%) in the lateralized group and 22 (91.7%) in the non-lateralized group (p <0.001). AVS interpretation with SC leads to significant clinical improvement in both patients who underwent surgery and those managed conservatively.

    Full Text Available Background: This study aimed to modify de Man Rogosa Sharpe culture medium (termed MRS for selective cultivation of probiotics strain for the consumption by the strictly vegetarian human population. Vegetarian probiotic foods by definition must be free from all animal-derived ingredients. This not only includes the product ingredients but the probiotic inoculum as well. Probiotic starter cultures are traditionally grown and stored in media containing milk or meatderived ingredients. The presence of these ingredients makes the probiotic cell concentrates unsuitable for use in vegetarian products and thus creates the need for a growth medium which isfree from animal-derived ingredients. Present study investigated the growth of a strain of Lactobacillus lactis in MRS. The present invention relates in general to a bacterial culture media,and more specifically a complex microbial culture media, based on plant seed powder extract in place of animal extract for probiotic bacterial growth.Methods: Lactobacillus lactis, a probiotic, was grown in standard MRS culture medium as well as in our various test media (TM containing various vegetal source in place of beef extract, yeast extract and peptone as in case of MRS. The inoculated culture mediums were incubated at 37C for 72 hours and growth of probiotic is recorded at regular intervals. The growth was recorded as Colony Forming Units (CFUs.Results: The best growth of probiotic is observed in TM 2. TM 2 is the leguminous seed extract. Starter culture mediums for probiotics or other bacteria primarily contain protein from animal source. The possibility of using vegetal protein from TM 2 extract in place of peptones and meat extract for the nitrogen supplementation of culture media for the growth of lactic acid bacteria has been demonstrated.Functional Foods in Health and Disease 2012, 2(10:369-378 Conclusion: The absolute vegetarian culture medium containing TM 2 is better than standard MRS for the

    A number of strategic investigations is carried out to determine if and to what extent normalization of public contracts can support the position of the Dutch businesses and industry in the European market. The strategic investigation in this report is limited to clusters within the Dutch energy utilities' sector concerning the production, transportation and distribution of electricity and heat, and the distribution of natural gas in the Netherlands. The results of this report can support those companies that will acquire orders via public contracts in the future; companies that wish to continue existing relations with tender services, if they will change to public contracts; and tender services that will have to put their orders via public contracts.Relevant European guidelines and accompanying procedures are outlined. The economic interest of the total Dutch energy sector and the different energy clusters in the Netherlands is discussed. Also attention is paid to the process of normalization, the role of standards and other technical documents regarding the guidelines Public Contracts. An inventory of available standards and conceptual standards is given for each energy cluster. Finally, an indication is given of the actual compliance of the guidelines. 5 figs., 4 tabs., 16 appendices

    A strictly aerobic, Gram-stain-positive, motile and spore-forming bacterium, strain 3nP4(T), was isolated from the Puge hot spring located in the south-western geothermal area of China. Strain 3nP4(T) grew at 38-66 °C (optimum 57-60 °C), at pH 6.0-9.3 (optimum 7.0-7.5) and with 0-4 % (w/v) NaCl (optimum 0-0.5 %). Phylogenetic analysis of 16S rRNA gene sequences, as well as DNA-DNA relatedness values, indicated that the isolate represents a novel species of the genus Anoxybacillus, related most closely to Anoxybacillus voinovskiensis DSM 12111(T). Strain 3nP4(T) had diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and one unidentified phospholipid as major polar lipids and iso-C15 : 0 and iso-C17 : 0 as major fatty acids, which are both typical chemotaxonomic characteristics of the genus Anoxybacillus. The mean DNA G+C content of strain 3nP4(T) was 39.2±0.95 mol% (HPLC). A distinctive characteristic of the novel isolate was its extreme reliance on vitamin mixture or yeast extract for growth. Based on data from this taxonomic study using a polyphasic approach, strain 3nP4(T) is considered to represent a novel species of the genus Anoxybacillus, for which the name Anoxybacillus vitaminiphilus sp. nov. is proposed. The type strain is 3nP4(T) ( = CGMCC 1.8979(T) = JCM 16594(T)).

    Full Text Available Abstract Background Elevated blood O2 affinity enhances survival at low O2 pressures, and is perhaps the best known and most broadly accepted evolutionary adjustment of terrestrial vertebrates to environmental hypoxia. This phenotype arises by increasing the intrinsic O2 affinity of the hemoglobin (Hb molecule, by decreasing the intracellular concentration of allosteric effectors (e.g., 2,3-diphosphoglycerate; DPG, or by suppressing the sensitivity of Hb to these physiological cofactors. Results Here we report that strictly fossorial eastern moles (Scalopus aquaticus have evolved a low O2 affinity, DPG-insensitive Hb - contrary to expectations for a mammalian species that is adapted to the chronic hypoxia and hypercapnia of subterranean burrow systems. Molecular modelling indicates that this functional shift is principally attributable to a single charge altering amino acid substitution in the β-type δ-globin chain (δ136Gly→Glu of this species that perturbs electrostatic interactions between the dimer subunits via formation of an intra-chain salt-bridge with δ82Lys. However, this replacement also abolishes key binding sites for the red blood cell effectors Cl-, lactate and DPG (the latter of which is virtually absent from the red cells of this species at δ82Lys, thereby markedly reducing competition for carbamate formation (CO2 binding at the δ-chain N-termini. Conclusions We propose this Hb phenotype illustrates a novel mechanism for adaptively elevating the CO2 carrying capacity of eastern mole blood during burst tunnelling activities associated with subterranean habitation.

  13. Light perception in two strictly subterranean rodents: life in the dark or blue?

    Full Text Available BACKGROUND: The African mole-rats (Bathyergidae, Rodentia are strictly subterranean, congenitally microphthalmic rodents that are hardly ever exposed to environmental light. Because of the lack of an overt behavioural reaction to light, they have long been considered to be blind. However, recent anatomical studies have suggested retention of basic visual capabilities. In this study, we employed behavioural tests to find out if two mole-rat species are able to discriminate between light and dark, if they are able to discriminate colours and, finally, if the presence of light in burrows provokes plugging behaviour, which is assumed to have a primarily anti-predatory function. METHODOLOGY/PRINCIPAL FINDING: We used a binary choice test to show that the silvery mole-rat Heliophobius argenteocinereus and the giant mole-rat Fukomys mechowii exhibit a clear photoavoidance response to full-spectrum ("white", blue and green-yellow light, but no significant reaction to ultraviolet or red light during nest building. The mole-rats thus retain dark/light discrimination capabilities and a capacity to perceive short to medium-wavelength light in the photopic range of intensities. These findings further suggest that the mole-rat S opsin has its absorption maximum in the violet/blue part of the spectrum. The assay did not yield conclusive evidence regarding colour discrimination. To test the putative role of vision in bathyergid anti-predatory behaviour, we examined the reaction of mole-rats to the incidence of light in an artificial burrow system. The presence of light in the burrow effectively induced plugging of the illuminated tunnel. CONCLUSION/SIGNIFICANCE: Our findings suggest that the photopic vision is conserved and that low acuity residual vision plays an important role in predator avoidance and tunnel maintenance in the African mole-rats.

    Cross-sectional study. The goal of this study is to translate the English version of the Modified Low Back Pain Disability Questionnaire (MDQ) into a Dutch version and investigate its clinimetric properties for patients with nonspecific chronic low back pain (CLBP). Fritz et al (2001) developed a modified version of the Oswestry Disability Questionnaire (ODI) to assess functional status and named it the MDQ. In this version, a question regarding employment and homemaking ability was substituted for the question related to sex life. Good clinimetric properties for the MDQ were identified but up until now it is not clear whether the clinimetric properties of the MDQ would change if it was translated into a Dutch version. Translation of the MDQ into Dutch was done in 4 steps. Test-retest reliability was investigated using the intraclass correlation coefficient (ICC) model. Validity was calculated using Pearson correlations and a 2-way analysis of variance for repeated measures. Finally, responsiveness was calculated with the area under the curve (AUC), minimal detectable change (MDC), and the standardized response mean (SRM). A total of 80 completed questionnaires were collected in 3 different hospitals and a total of 43 patients finished a 9 weeks intervention period, completing the retest. Test-retest reliability was excellent with an ICC of 0.89 (95% confidence interval [CI], 0.74-0.95). To confirm the convergent validity, the MDQ answered all predefined hypothesises (r = -0.65-0.69/P = 0.01-0.00) and good results for construct validity were found (P = 0.02). The MDQ had an AUC of 0.64 (95% confidence interval [CI], 0.47-0.81), an MDC of 8.80 points, and a SRM of 0.65. The Dutch version of the MDQ shows good clinimetric properties and is shown to be usable in the assessment of the functional status of Dutch-speaking patients with nonspecific CLBP. 3.

    Disturbed body perception may play a role in the aetiology of chronic low back pain (LBP). The Fremantle Back Awareness Questionnaire (FreBAQ) is currently the only self-report questionnaire to assess back-specific body perception in individuals with LBP. To perform a cross-cultural adaptation of the FreBAQ into Dutch. Psychometric study. A Dutch version of the FreBAQ was generated through forward-backward translation, and was completed by 73 patients with LBP and 73 controls to assess discriminant validity. Structural validity was assessed by principal component analysis. Internal consistency was assessed by the Cronbach's alpha coefficient. Construct validity was assessed by examining the relationship with clinical measures (Numerical Rating Scale pain, Oswestry Disability Index (ODI), Tampa Scale for Kinesiophobia). Test-retest reliability was assessed in a subgroup (n = 48 with LBP and 48 controls) using intraclass correlation coefficients (ICC), standard error of measurement (SEM) and minimal detectable change (MDC 95%) RESULTS: The Dutch FreBAQ showed one component with eigenvalue >2. Cronbach's alpha values were respectively 0.82 and 0.73 for the LBP and control group. ICC values were respectively 0.69 and 0.70 for the LBP and control group. In the LBP group, the SEM was 3.9 and the MDC (95%) was 10.8. The LBP group (ODI 22 ± 21%) scored significantly higher on the Dutch FreBAQ than the control group (ODI 0%) (11 ± 7 vs. 3 ± 9, p Dutch FreBAQ scores correlated significantly with higher ODI scores (rho = 0.30, p = 0.010), although not with pain (rho = 0.10, p = 0.419) or kinesiophobia (r = 0.14, p = 0.226). The Dutch version of the FreBAQ can be considered as unidimensional and showed adequate internal consistency, sufficient test-retest reliability and adequate discriminant and construct validity in individuals with and without LBP. It can improve our understanding on back-specific perception in the Dutch-speaking population with LBP

    Preventing the spread of multidrug-resistant Gram-negative bacteria (MDRGNB) is a public health priority. However, the definition of MDRGNB applied for planning infection prevention measures such as barrier precautions differs depending on national guidelines. This is particularly relevant in the Dutch-German border region, where patients are transferred between healthcare facilities located in the two different countries, because clinicians and infection control personnel must understand antibiograms indicating MDRGNB from both sides of the border and using both national guidelines. This retrospective study aimed to compare antibiograms of Gram-negative bacteria and classify them using the Dutch and German national standards for MDRGNB definition. A total of 31,787 antibiograms from six Dutch and four German hospitals were classified. Overall, 73.7% were no MDRGNB according to both guidelines. According to the Dutch and German guideline, 7772/31,787 (24.5%) and 4586/31,787 (12.9%) were MDRGNB, respectively ( p Dutch-German border, as it cannot be assumed that MDRGNB requiring special hygiene precautions are marked in the transferred antibiograms in accordance with both national guidelines.

    1993-01-01

    Dutch chemical producers have negotiated a long-term agreement with government ministries to reduce emissions of a wide range of chemicals. Industry association Vereniging van de Nederlandse Chemische Industrie (VNCI; Leidschendam) says implementing the commitment will cost companies Dfl 10 billion ($5.4 billion) between 1993 and 2000. VNCI technical director Wim Quik welcomes the accord, which he describes as a management contract, saying, Rather than have legislation, there is a certain adjustment available. Peter Santen, managing director of midsized chemicals player Cindu Chemicals (Uithoorn, the Netherlands) voices some concern about the details of the accord, but adds, we are flexible in trying to agree with the contents of the covenant [it] is better than having new rules from law. The Dutch government, traditionally eager for consensus, has struck a number of such deals with Dutch industries - including packaging, metal, and tire - to reduce emissions and set up environmental management programs. The effort is based on the government's National Environmental Policy Plans - NMP and NMP Plus. Targets for emissions reduction by the chemical industry were provided by a government-funded environmental research institute

  2. Partnering for climate change adaptations by Dutch housing associations

    Directory of Open Access Journals (Sweden)

    2015-06-01

    climate change adaptation is the best course, which implies attaching the adaptation policy to existing policy frameworks. This would make policymakers aware of the topic of climate change adaptation and they could look for synergies between measures that were already planned and measures related to climate change adaptations. The refurbishment and maintenance process of housing associations provides opportunities for the mainstreaming of adaptation measures. Housing associations are facing an ageing stock that needs to be improved if it is to continue to meet the ever increasing basic requirements of tenants in terms of quality and comfort and increasingly strict energy-efficiency standards. Since climate change is occurring gradually, there is still time to adapt the building stock gradually, in step with the renovation and maintenance cycles of the housing associations. Bringing in external players, especially municipalities and water authorities, would appear to be a highly feasible approach, given their shared interest in the quality of life in local areas. Bringing together the construction partners requires governance tools that inform them of the benefits of partnering. Particularly if construction companies are to be responsible for the renovation and the maintenance for the rest of the service life of the dwellings, they could focus on improved design solutions that aim to create resilient dwellings, and/or using materials that would be less affected by the effects of climate change. The role of tenants in the implementation of climate change adaptations is primarily that they might exert ‘bottom-up’ pressure by requesting action from housing associations. But for this to happen, they would likely need to be informed about the effects of climate change on their dwellings and/or neighbourhoods, in order for them to be motivated to ensure that their homes are climate change resilient.

    The Dutch Working Party on Antibiotic Policy in collaboration with the Dutch Association of Chest Physicians, the Dutch Society for Intensive Care and the Dutch College of General Practitioners have updated their evidence-based guidelines on the diagnosis and treatment of community-acquired pneumonia (CAP) in adults who present to the hospital. This 2016 update focuses on new data on the aetiological and radiological diagnosis of CAP, severity classification methods, initial antibiotic treatment in patients with severe CAP and the role of adjunctive corticosteroids. Other parts overlap with the 2011 guideline. Apart from the Q fever outbreak in the Netherlands (2007-2010) no other shifts in the most common causative agents of CAP or in their resistance patterns were observed in the last five years. Low-dose CT scanning may ultimately replace the conventional chest X-ray; however, at present, there is insufficient evidence to advocate the use of CT scanning as the new standard in patients evaluated for CAP. A pneumococcal urine antigen test is now recommended for all patients presenting with severe CAP; a positive test result can help streamline therapy once clinical stability has been reached and no other pathogens have been detected. Coverage for atypical microorganisms is no longer recommended in empirical treatment of severe CAP in the non-intensive care setting. For these patients (with CURB-65 score >2 or Pneumonia Severity Index score of 5) empirical therapy with a 2nd/3rd generation cephalosporin is recommended, because of the relatively high incidence of Gram-negative bacteria, and to a lesser extent S. aureus. Corticosteroids are not recommended as adjunctive therapy for CAP.

    1997-01-01

    Because of the lack of experience with permits in the Netherlands, and in view of the similarities between various other tradeable permit systems, the functioning of Dutch systems of tradeable fish, milk and manure quotas is discussed. Evaluation of these systems is based on criteria of effectiveness, target-group efficiency and government efficiency. These systems of tradeable permits appear to constitute a successful addition to the Dutch policy of direct regulation. Considering this, and the favorable American experience with the Emissions Trading Program, tradeable emission permits deserve a chance to be implemented in Dutch environmental policy. The question remains, however, whether the Dutch government is ready for such a step. 28 refs

    Two strict halophilic bacterial strains, Halobacillus trueperi SS1, and Halobacillus trueperi SS3, and three halotolerant bacterial strains, Shewanella algae SS2, Halomonas venusta SS5, and Marinomonas sp. SS8 of Lunsu salt water body, Himachal Pradesh, India, were selected to study the mechanism of salt tolerance and the role of osmolytes therein. A combination of flame photometry, chromatographic and colorimetric assays was used to study the mechanism of salt tolerance in the selected strict halophilic and halotolerant bacterial strains. The strict halophiles and, one of the halotolerants, Marinomonas sp. SS8 were found to utilize both "salt-in strategy" and "accumulation of compatible solutes strategy" for osmoregulation in hypersaline conditions. On the contrary, the remaining two halotolerants used "accumulation of compatible solutes strategy" under saline stress and not the "salt-in strategy". The present study suggests towards distinct mechanisms of salt tolerance in the two classes, wherein strict halophiles accumulate compatible solutes as well as adopt salt-in strategy, while the halotolerant bacteria accumulate a range of compatible solutes, except Marinomonas sp. SS8, which utilizes both the strategies to combat salt stress.

    In view of the shortcomings of the organisation of the perioperative process that have been ascertained by the Dutch Health Inspectorate (IGZ), the Inspectorate has requested hospitals and care professionals to implement measures to improve this situation. In response to the IGZ's first report, the Dutch Institute for Healthcare Improvement (CBO) has developed the national, multiprofessional guidelines entitled 'Preoperative Trajectory' which were published in January 2010. Implementation of these guidelines should improve communication between professionals and lead to standardization and transparency of the preoperative patient care process, with uniform handovers and clear responsibilities. These guidelines are the first to provide recommendations at process of care level which are intended to increase patient safety and reduce the risk of damage to patients.

  9. The Epidemiology of Hip and Major Osteoporotic Fractures in a Dutch Population of Community-Dwelling Elderly: Implications for the Dutch FRAX® Algorithm.

    Full Text Available Incidence rates of non-hip major osteoporotic fractures (MOF remain poorly characterized in the Netherlands. The Dutch FRAX® algorithm, which predicts 10-year probabilities of hip fracture and MOF (first of hip, humerus, forearm, clinical vertebral, therefore incorporates imputed MOF rates. Swedish incidence rate ratios for hip fracture to MOF (Malmo 1987-1996 were used to perform this imputation. However, equality of these ratios between countries is uncertain and recent evidence is scarce. Aims were to estimate incidence rates of hip fracture and MOF and to compare observed MOF rates to those predicted by the imputation method for the Netherlands.Using hospitalisation and general practitioner records from the Dutch PHARMO Database Network (2002-2011 we calculated age-and-sex-specific and age-standardized incidence rates (IRs of hip and other MOFs (humerus, forearm, clinical vertebral and as used in FRAX®. Observed MOF rates were compared to those predicted among community-dwelling individuals ≥50 years by the standardized incidence ratio (SIR; 95% CI.Age-standardized IRs (per 10,000 person-years of MOF among men and women ≥50 years were 25.9 and 77.0, respectively. These numbers were 9.3 and 24.0 for hip fracture. Among women 55-84 years, observed MOF rates were significantly higher than predicted (SIR ranged between 1.12-1.50, depending on age. In men, the imputation method performed reasonable.Observed MOF incidence was higher than predicted for community-dwelling women over a wide age-range, while it agreed reasonable for men. As miscalibration may influence treatment decisions, there is a need for confirmation of results in another data source. Until then, the Dutch FRAX® output should be interpreted with caution.

    2018-03-23

    The Dutch animal welfare law includes so-called principle-based standards. This means that the objective is described in abstract terms, enabling farmers to comply with the law in their own way. Principle-based standards are, however, difficult for the inspection agency to enforce because strict limits are missing. This pilot project aimed at developing indicators (measurements) to assess the climate in pig houses, thus enabling the enforcement of principle-based standards. In total, 64 farms with weaners and 32 farms with growing-finishing pigs were visited. On each farm, a set of climate-related measurements was collected in six pens. For each of these measurements, a threshold value was set, and exceeding this threshold indicated a welfare risk. Farm inspections were carried out during winter and spring, thus excluding situations with heat stress. Assessment of the variation and correlation between measurements reduced the dataset from 39 to 12 measurements. Using a principal components analysis helped to select five major measurements as warning signals. The number of exceeded thresholds per pen and per farm was calculated for both the large (12) and small (five) sets of measurements. CO₂ and NH₃ concentrations were related to the outside temperature. On colder days, there was less ventilation, and thus CO₂ and NH₃ concentrations increased. Air quality, reflected in the CO₂ and NH₃ concentrations, was associated with respiratory problems. Eye scores were positively correlated with both pig and pen fouling, and pig and pen fouling were closely related. We selected five signal indicators: CO₂, NH₃, and tail and eye score for weaners and finishers, and added ear score for weaners and pig fouling for growing-finishing pigs. The results indicate that pig farms can be ranked based on five signal indicators related to reduced animal welfare caused by climatic conditions. This approach could be adopted to other principle-based standards for pigs as well

    2010-02-01

    Full Text Available This article discusses the strategies that sustainable entrepreneurs use to interact with their environment in the Dutch construction industry. The Dutch construction industry is under great pressure to move towards sustainability, and entrepreneurs are believed to be able to play a large role in this transition by introducing new products and new business practices. But how can entrepreneurs prosper in an environment that is not geared up towards such a change? And which strategies do they use to bend conditions in their favor? In this article we make use of the Market and System Failure Framework to analyze the pressures that entrepreneurs are confronted with when introducing sustainable innovations. We recognize that these pressures can be seen as bottlenecks, but that market and system failures can also create entrepreneurial opportunities. We interviewed 16 entrepreneurs in the Dutch construction industry to determine the influences they experienced from their environment and the strategies they use to deal with these. We conclude that we can distinguish between system building and following entrepreneurs, where the former aims to build a new system to challenge the old one, whereas the latter rather makes use of existing structures to build a business. We find that both strategies can be successful and that overall, the entrepreneurs confirm the belief that sustainability on people, planet and transparency aspects, can contribute very well to the long term profitability of the businesses the entrepreneurs are running. These in-depth insights into the influences from the context on the one hand, and the entrepreneurs’ strategic reactions on the other hand, contribute to our understanding of the interactions between entrepreneurs and the system context. This can help us to more effectively stimulate and support innovating entrepreneurs to contribute to the transition towards sustainability.

Method Study group: Indigent South African women managed in the tertiary hospitals of the Pretoria Academic Complex. Since 1997 a standard definition of women with severe acute maternal morbidity (SAMM, also referred to as a Nearmiss, has been used in the Pretoria Academic Complex. All cases of SAMM and maternal deaths (MD were entered on the Maternal Morbidity and Mortality Audit System programme (MaMMAS. A comparison of outcome of severely ill women who had complications of hypertension in pregnancy was performed between 1997–1998 (original protocol and 2002–2003 (strict protocol. Data include women referred from outside the Pretoria Academic Complex area to the tertiary hospitals. Results Between 1997–1998 there were 79 women with SAMM and 18 maternal deaths due to complications of hypertension, compared with 91 women with SAMM and 13 maternal deaths in 2002–2003. The mortality index (MI declined from 18.6% to 12.5% (OR 0.62, 95% CI 0.27–1.45.

    The Dutch energy distribution companies are again facing important adaptations to current market forces. The operational activities of the conventional energy distribution companies are split into monopoly tasks and commercial activities. By separation of functions and by further technological developments and market trends quite different types of companies will emerge, such as grid operators, energy-telecommunications-environment concerns and energy sellers. Some companies will focus on grid operation, while others will clearly opt for more commercial enterprising. Just like other private companies energy companies will develop new activities in other markets based on their own corporate strategies. Grid operation may then become only a mirror element or be abandoned altogether. 5 figs

    The no-fault liability principle of nuclear liability regime, its compensation schemes, sociological and legal grounds of its construction as well as liberation grounds are analysed. The simple existence of causation of damage and nuclear accident without necessity of proving negligence or any other type of fault on the part of the operator as an adequate basis for the operator’s strict liability is highlighted thus simplifying the litigation process eliminating potential obstacles, especially such as might exist with the burden of proof. The question of weighing the interests of society in the development of nuclear industry, the necessary extent of protection of victims of nuclear accidents and the interests of operators of nuclear facilities as main determinants of the strict nature of nuclear liability is also described.

    2015-10-01

    This cross-sectional study explored the extent and impact of mobile device-based Sleep Time-Related Information and Communication Technology (STRICT) use among American adolescents (N = 3139, 49.3% female, mean age = 13.3 years). Nearly 62% used STRICT after bedtime, 56.7% texted/tweeted/messaged in bed, and 20.8% awoke to texts. STRICT use was associated with insomnia, daytime sleepiness, eveningness, academic underperformance, later bedtimes and shorter sleep duration. Moderation analysis demonstrated that the association between STRICT use and insomnia increased with age, the association between STRICT use and daytime sleepiness decreased with age, and the association between STRICT use and shorter sleep duration decreased with age and was stronger in girls. Insomnia and daytime sleepiness partially mediated the relationship between STRICT use and academic underperformance. Our results illustrate the adverse interactions between adolescent STRICT use and sleep, with deleterious effects on daytime functioning. These worrisome findings suggest that placing reasonable limitations on adolescent STRICT use may be appropriate. Copyright © 2015 The Foundation for Professionals in Services for Adolescents.

  10. The application of strict criminal liabilities to spillage of oil: the practical impact on effective spill response

    International Nuclear Information System (INIS)

    Gallagher, J.J.

    2002-01-01

    The Federal Water Pollution Control Act as amended by the Oil Pollution Act of 1990 provides criminal penalties in oil spills that result from criminal activity, gross negligence or wilful misconduct on the part of the spiller. Nevertheless, the Department of Justice has seen fit to reach into unrelated legislation to potentially apply strict criminal liability to any oil spill regardless of intent. Strict criminalization of accidental oil spills is demonstrably counterproductive to effective protection of the environment from the effect of spills since it poses a serious impediment to cooperation and coordination by and between those charged by law to respond to them. This impediment is particularly dangerous since it threatens the proper functioning of the inherently sensitive ''troika'' Unified Command Structure that has evolved in spill response management in response to OPA-90 management requirements. Introduction of strict criminal liability for accidental spills is also particularly troublesome in that it must enlist unrelated law to influence an area that has been addressed specifically by legislation designed for that purpose; legislation that has worked well in the past 30 years to both regulate the target activities while successfully achieving the objective of protecting and improving environment quality.

    Tersmette, W; van Bodegom, D; van Heemst, D; Stott, D; Westendorp, R

    2013-01-01

    The world population is ageing and healthcare services require trained staff who can address the needs of older patients. In this study we determined how current medical education prepares Dutch students of medicine in the field of Gerontology and Geriatrics (G&G). Using a checklist of the essentials of G&G, we assessed Dutch medical education on three levels. On the national level we analysed the latest National Blueprint for higher medical education (Raamplan artsopleiding 2009). On the faculty level we reviewed medical curricula on the basis of interviews with program directors and inspection of course materials. On the student level we assessed the topics addressed in the questions of the cross-institutional progress test (CIPT). The National Bluepr int contains few specific G&G objectives. Obligatory G&G courses in medical schools on average amount to 2.2% of the total curriculum measured as European Credit Transfer System units (ECTS). Only two out of eight medical schools have practical training during the Master phase in the form of a clerkship in G&G. In the CIPT, on average 1.5% of questions cover G&G. Geriatric education in the Netherlands does not seem to be in line with current demographic trends. The National Blueprint falls short of providing sufficiently detailed objectives for education on the care of older people. The geriatric content offered by medical schools is varied and incomplete, and students are only marginally tested on their knowledge of G&G in the CIPT.

    2007-01-01

    As information technology creates opportunities for cooperation which crosses the boundaries between healthcare institutions, it will become an integral part of the Dutch healthcare system. Along with many involved organizations in healthcare the National IT Institute for Healthcare in the Netherlands (NICTIZ) is working on the realization of a national IT infrastructure for healthcare and a national electronic patient record (EPR). An underlying national architecture is designed to enable the Dutch EPR virtually, not in a national database, nor on a patient's smartcard. The required secure infrastructure provides generic functions for healthcare applications: patient identification, authentication and authorization of healthcare professionals. The first national applications in the EPR program using a national index of where patient data is stored, are the electronic medication record and the electronic record for after hours GP services. The rollout of the electronic medication record and electronic record for after hours GP services has been started in 2007. To guarantee progress of electronic data exchange in healthcare in the Netherlands we have primarily opted for two healthcare applications: the electronic medication record and the electronic record for after hours GP services. The use of a national switch-point containing the registry of where to find what information, guarantees that the professional receives the most recent information and omits large databases to contain downloaded data. Proper authorization, authentication as well as tracing by the national switchpoint also ensures a secure environment for the communication of delicate information.

  13. Procedural Justice in Dutch Administrative Court Proceedings

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available In this paper we discuss recent developments in administrative court proceedings in the Netherlands, called the New Approach. Along with developments leading to the New Approach, it became clear that the insights from research on procedural justice deserve particular attention. The goals of the judge's actions in this respect are both that the proceedings are fair and just and that parties perceive the way they are being treated during proceedings as fair and just.Within the New Approach we discern five procedural justice elements: (1 respect, (2 voice and due consideration, (3 some influence on how proceedings will continue, (4 an explanation of how the proceedings will continue and (5 direct interpersonal contact.The introduction of the New Approach shows two important bottlenecks in Dutch administrative court proceedings, which are (i the possible or supposed collision between legally right outcomes and  procedural justice and (ii the lack of uniformity and predictability.Although what we describe and discuss in this paper focuses on the Dutch situation, many of these considerations apply to administrative court proceedings in other countries. The themes and difficulties that face the administrative law judge seem to be common to many countries.

  14. Netherlands as producer of energy knowledge. Dutch governmental efforts for energy R and D in an international perspective

    2006-04-01

    The Dutch Ministry of Economic Affairs aims to link its transition policy in a broader context to international energy - and climate policy. A clear view on the Dutch position in the field of energy research policy is an important aspect of this international anchoring of the transition policy. For that purpose this report offers a first insight in the scope, the quality and the focus of Dutch energy R and D budget in comparison with the situation in a number of other countries. Furthermore, the attention is directed at recent developments and issues involved in the organisation of energy research. Several instruments for priority setting and organisational issues are recommended for consideration in the process of the international anchoring of transition policy. With regard to the per capita budgets for energy R and D, the Netherlands is leading together with Japan and the United States. Concerning the knowledge position in the field of energy, as of yet no research has been conducted expressing this knowledge position in publications, citations and patents. However, in the programming for the Dutch energy research strategy (EOS) a positive picture is presented. The role of the Netherlands in the European Framework Programmes indirectly indicates a good position as well. However, the scope of the Dutch government budget for energy R and D has been relatively strongly decreasing over the past years. The private contributions to energy R and D in the Netherlands are reasonable (50%), but the Dutch government expects that these - as a result of liberalisation - will decrease as well. In the Netherlands a relatively great part of the budget is spent on sustainable energy and energy conservation (together 70%). The Netherlands spend more on biomass and in particular on wind energy and less on solar energy than is the case in the other countries. Compared to the other countries, the Dutch budget for energy conservation has been remarkably evenly divided over the

    This research assesses to what extent current Dutch energy transition policy instruments for the existing housing stock can fulfil local executive actors' needs and instigate adoption of energy efficiency measures by them. This is done by studying energy policy instruments for the existing housing stock in the Netherlands and in other European countries, and by an empirical research, which analyses barriers and needs of local executive actors. We found that, despite current Dutch energy transition policy instruments for the existing housing stock seem to fulfil local executive actors' needs to a large extent, complementary policy instruments are needed to stimulate and pressure the incumbent renovation regime. A long-term oriented financial rewarding system is needed to build up a structural market for the deployment of renewables, to increase the number of specialist jobs in the building sector, and to stimulate the development of integrated, standardized, building components. Furthermore, a long-term oriented financial rewarding system for energy efficiency investments in housing renovation projects, and a low VAT rate applied to energy efficient renovation measures, are needed. Finally, enforcement possibilities and sanctions (fines) should become an integrative part of Dutch energy certification regulation to make the certificate become part of a value chain.

    2013-01-01

    As a result of recent reforms in Dutch health care, healthcare providers are having to operate more and more like commercial organisations and adopt some of the rules prevailing in the profit sector. Because missions statements can be an efficient means of useful communication with internal and external stakeholders they can make a useful contribution to the way healthcare institutions are managed and to their status and reputation. Research shows that in view of this the quality of the messages conveyed via mission statements is important. To ascertain which stakeholders are mentioned in the mission statements of Dutch mental healthcare providers and to quantify the quality of the messages conveyed to them via mission statements. We examined the mission statements of 34 mental health providers to find out which stakeholders were included. The message conveyed to the stakeholders was quantified by means of a validated measuring instrument devised specifically for this purpose. Patients were referred to in all mission statements and the quality of the messages conveyed was of higher quality than the messages conveyed to other stakeholders. Other important stakeholders on whom the institutions depended were referred to much less frequently and the quality of sections of text referring to them was definitely inferior. Mission statements frequently serve as management tool for Dutch mental healthcare providers. The potential benefits that these statements could bestow on the providers are not being fully exploited because the standard of communication with several internal and external stakeholders is of poor quality.

  17. Requests for euthanasia in general practice before and after implementation of the Dutch Euthanasia Act

    2010-01-01

    Background The Netherlands was the first country in the world to implement a Euthanasia Act in 2002. It is unknown whether legalising euthanasia under strict conditions influences the number and nature of euthanasia requests. Aim To investigate changes in the number of, and reasons for, requests for euthanasia in Dutch general practice after implementation of the Euthanasia Act. Design of study Retrospective dynamic cohort study comparing 5 years before (1998–2002) and 5 years after (2003–2007) implementation of the Act. Method Standardised registration forms were used to collect data on requests for euthanasia via the Dutch Sentinel Practice Network. This network of 45 general practices is nationally representative by age, sex, geographic distribution, and population density. Results The mean annual incidence of requests before implementation amounted to 3.1/10 000 and thereafter to 2.8/10 000 patients. However, trends differed by sex. The number of requests by males decreased significantly from 3.7/10 000 to 2.6/10 000 (P = 0.008); the requests by females increased non-significantly from 2.6/10 000 to 3.1/10 000. Before and after implementation, cancer remained the major underlying disease for requesting euthanasia: 82% versus 77% for men; 73% versus 75% for females. Pain was a major reason for a request, increasing in the period before implementation (mean 27%), but declining in the period thereafter (mean 22%). Loss of dignity became a less important reason after implementation (from 18% to 10%, P = 0.04), predominantly due to a marked decrease in the number of females citing it as a reason (from 17% to 6%, P = 0.02). Conclusion There was no increase in demand for euthanasia after implementation of the Euthanasia Act. Pain as a reason for requesting euthanasia showed an increasing trend before implementation, but declined thereafter. Loss of dignity as a reason declined, especially in females. PMID:20353671

  18. Risk-avoidance or utmost commitment. : Dutch focus group research on views on cohabitation and marriage.

    Directory of Open Access Journals (Sweden)

    2015-02-01

    Full Text Available Background: Dutch adults grew up in a highly individualized country, characterized by high divorce rates, which may have influenced their views on cohabitation and marriage. Objective: We examine Dutch adults' perceptions of how similar or different cohabitation and marriage are, whether they believe that cohabitation would be a strategy to avoid the risk of divorce, as well as their views on why people marry in individualized societies. Methods: We analyze seven focus group interviews with 40 Dutch participants, collected in 2012 in Rotterdam, the Netherlands. Results: Many participants discussed differences and similarities between cohabitation and marriage in a context of high divorce rates, and frequently viewed cohabitation as a risk-reduction strategy. At the same time, marriage was often seen as ―the real deal‖, in terms of legal arrangements, but also as a symbol of utmost commitment. Less educated participants viewed more financial advantages in cohabitation compared to marriage, and felt more strongly about the symbolic value of marriage than their highly educated counterparts. There was strong consensus that there is not, and should not be, a social norm to marry. Conclusions: In a context of high relationship instability, cohabitation has become a risk-reduction strategy. When norms to marry are weak, people may marry in order to emphasize the uniqueness of their relationship. However, the individualistic nature of Dutch society is mirrored in respondents' reluctance to set standards or proscribe norms on why and when to marry and their emphasis that cohabitation can also imply high levels of commitment.

    To investigate which valid and reliable patient-reported outcome measures (PROMs) are available for foot and ankle disorders in the Dutch population, and which of these is the most suitable for uniform use. Systematic review. PubMed, Embase and Google Scholar were systematically searched for relevant articles; subsequently two researchers screened first the title and the abstract, and then the full article within a selection of these articles. Studies that described a validation process for foot- and ankle-PROMs in a Dutch population were included. Data on measurement characteristics and translation procedure were extracted, and methodological quality of the studies was assessed using the COSMIN checklist. ('COSMIN' stands for 'Consensus-based standards for the selection of health status measurement instruments'.) Two general foot- and ankle-PROMs in the Dutch language were validated: the Foot and Ankle Outcome Score (FAOS) and the Foot and Ankle Ability Measurement (FAAM); two foot-PROMs: the Manchester Foot Pain and Disability Index (MFPDI) and the 5-point Foot Function Index (FFI-5pt) were also validated. There were also two disorder-specific PROMs available in Dutch: the Victorian Institute of Sports Assessment-Achilles (VISA-A) for Achilles tendinopathies and the Foot Impact Scale for Rheumatoid Arthritis (FIS-RA) for rheumatoid arthritis patients. The FAOS and the FFI-5pt showed the strongest evidence for having good measurement characteristics. Currently, we regard the FAOS as the most appropriate foot- and ankle-PROM for general foot and ankle problems. Further studies of higher methodological quality are, however, required to draw firmer conclusions.

    2017-07-01

    In this cross-cultural study we investigated how study participants from China, Ethiopia and the Netherlands operationalize the concept of meat and to what extent cultured meat fits or does not fit into this operationalization. We argue that combining the conceptual approaches symbolic boundaries and theory of social practices helps to better understand the possibly culturally dependent operationalization of the concept meat. Ten visiting graduate students from China, 10 from Ethiopia and 10 native Dutch graduate students completed freelist tasks, a pile sort task, interview and essay task, during a single session. We found that butchered animals are at the center of the concept of meat, although depending on culture not all animals are a source of meat. Symbolic boundaries were restricted or stretched depending on social practices within countries. Ethiopian participants applied strictly defined symbolic boundaries, where Chinese and Dutch participants used more broadly defined symbolic boundaries. Cultured meat was seen as a technology for the future and was positioned across the symbolic boundaries of meat. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Interest in self-esteem has been fuelled by the suggestion that level of self-esteem is associated with psychological well-being. In the present study, we translated the Rosenberg Self-Esteem Scale (RSES into the Dutch language and evaluated its psychometric properties in a sample of 442 adults. The results of both exploratory and confirmatory factor analyses confirmed that a single-factor solution provides the best fit. In addition, the Dutch RSES showed high internal consistency as well as high congruent validity. Overall, these findings support the usefulness of the Dutch RSES as a measure for global self-esteem.

  7. Actual heating energy savings in thermally renovated Dutch dwellings

    Majcen, Daša; Itard, Laure; Visscher, Henk

    2016-01-01

    The register of the Dutch social housing stock was analysed, containing 300.000 dwellings, renovated between 2010 and 2013. The main objective was twofold: to evaluate the performance gap in these dwellings before and after the renovation and to establish what renovation measures achieve the highest reduction of consumption, particularly in practice (actual savings). The results showed large performance gaps in dwellings with low R and high U values, local heating systems, changes from a non-condensing into a condensing boiler and upgrades to a natural ventilation system. Regarding the actual effectiveness of renovation measures, replacement of old gas boilers with more efficient ones yields the highest energy reduction, followed by deep improvements of windows. Installing mechanical ventilation yields a small reduction compared to other measures, but still much larger than theoretically expected. The paper shows once more that the calculation method currently in use cannot be considered accurate if compared to actual consumption. The study demonstrated that unrealistic theoretical efficiencies of heating systems and insulation values are causing a part of the performance gap. Nowadays, large datasets of buildings thermal performance and actual consumption offer an opportunity to improve these misconceptions. - Highlights: • Performance gap is lower in more efficient buildings. • Replacements of gas boilers – the most energy reduction among renovation measures. • Replacing the ventilation system yields a much larger reduction than expected. • How well are the standard values of the calculation methods defined? • Provide large public building performance databases including actual use data.

    International Nuclear Information System (INIS)

    Scheepers, M.J.J.

    1991-01-01

    Until 1986 landfill gas had a considerable value because of the relative high energy prices. It appeared also that landfill gas was formed in large quantities. However after the collapse of the energy prices in 1986 many new landfill gas projects were delayed or stopped. Recently, the gas emissions on landfills have attracted attention again, but now because of various environmental aspects. With respect to landfill management a well controlled gas extraction seems to be necessary. Utilisation of the gas is still favourable for economic reasons and because of energy savings. The Dutch policy for the next ten years will be reduction of the amount of waste by prevention and recycling. The organic fraction of the municipal solid waste (refuse from vegetables, fruit and garden), obtained by separation in households, will be composted. The other part will be burnt in incinerators. Only the remaining inert refuse will be deposited on landfills. (author)

    To assess the prevalence rates of self-reported sleep bruxism and awake bruxism and their associations with several demographical, exogenous, and psychosocial factors among Dutch adolescents. In a cross-sectional questionnaire survey, 4285 questionnaires were completed, with an about equal gender distribution and with ages ranging from 10 to 22 years. In the group of 4235 12- to 18-year-old adolescents, sleep bruxism had a reported prevalence of 14.8% and awake bruxism of 8.7%. Logistic regression analyses revealed that sleep bruxism was associated with female gender [OR = 1.49 (95% CI = 1.23-1.81)], pain or tense feeling in the jaws upon awakening in the morning [OR = 1.47 (95% CI = 1.17-1.86)], clicking joint sounds [OR = 1.31 (95% CI = 1.03-1.65)], stress [OR = 1.25 (95% CI = 1.00-1.55)], and depressive mood [OR = 1.35 (95% CI = 1.10-1.65)]. Awake bruxism was associated with orofacial pain [OR = 1.49 (95% CI = 1.16-1.91)], clicking joint sounds [OR = 1.50 (95% CI = 1.13-1.98)], scraping joint sounds [OR = 2.03 (95% CI = 1.21-3.37)], stress [OR = 1.36 (95% CI = 1.03-1.78)], depressive mood [OR = 1.82 (95% CI = 1.42-2.35)], and smoking [OR = 1.42 (95% CI = 1.06-1.89)]. Sleep bruxism and awake bruxism are common conditions among Dutch adolescents, with self-reported prevalence rates that are slightly higher than those derived from most large-scale studies on adults. Several predictor variables were found to be exclusively associated with either form of bruxism, corroborating the common suggestion that both circadian manifestations are, at least in part, different entities. © 2012 John Wiley & Sons A/S.

  12. The Dutch Approach to Local Climate Action

    International Nuclear Information System (INIS)

    Schellekens, R.

    2008-01-01

    In the Netherlands we are working with municipalities on the subjects of RES and RUE for over 15 years now. Over the last 4 years we worked with 250 out of 430 municipalities on setting up and executing their local climate policies. For this there was a national climate covenant between the national government, the association of municipalities and the association of provinces. The municipalities and provinces were supported through a subsidy scheme and the help of SenterNovem. Products like the climate menu, the climate scan and an organisational assessment were developed to aid the municipalities in their process. Through involvement of different stake holders within the municipality or a region concerning the climate policy and the execution thereof, production of RES is stimulated and goals on energy saving are more likely to be reached. Through the involvement of stake holders and by making climate change an integral part of the municipal organisation an irreversible process is started. Thus economic competitiveness and innovations are stimulated. The municipality and the region will gain economic strength through this. Results in the Netherlands on a municipal level are inspiring. More and more municipalities are developing long-term strategies at the moment. Goals like energy neutrality, climate neutrality and CO 2 neutrality in a set year are usually the basis of these strategies. Through these strategies Dutch municipalities become increasingly less dependent on energy sources outside their boarders. On a European level the Dutch approach ties in with the Covenant of Mayors which is launched by the EU.(author)

    Well-established metabolome sample preparation is a prerequisite for reliable metabolomic data. For metabolome sampling of a Gram-positive strict anaerobe, Clostridium acetobutylicum, fast filtration and metabolite extraction with acetonitrile/methanol/water (2:2:1, v/v) at -20°C under anaerobic conditions has been commonly used. This anaerobic metabolite processing method is laborious and time-consuming since it is conducted in an anaerobic chamber. Also, there have not been any systematic method evaluation and development of metabolome sample preparation for strict anaerobes and Gram-positive bacteria. In this study, metabolome sampling and extraction methods were rigorously evaluated and optimized for C. acetobutylicum by using gas chromatography/time-of-flight mass spectrometry-based metabolomics, in which a total of 116 metabolites were identified. When comparing the atmospheric (i.e., in air) and anaerobic (i.e., in an anaerobic chamber) processing of metabolome sample preparation, there was no significant difference in the quality and quantity of the metabolomic data. For metabolite extraction, pure methanol at -20°C was a better solvent than acetonitrile/methanol/water (2:2:1, v/v/v) at -20°C that is frequently used for C. acetobutylicum, and metabolite profiles were significantly different depending on extraction solvents. This is the first evaluation of metabolite sample preparation under aerobic processing conditions for an anaerobe. This method could be applied conveniently, efficiently, and reliably to metabolome analysis for strict anaerobes in air. © 2014 Wiley Periodicals, Inc.

    2014-12-01

    The metabolism of hydroxycinnamic acids by strictly heterofermentative lactic acid bacteria (19 strains) was investigated as a potential alternative energy route. Lactobacillus curvatus PE5 was the most tolerant to hydroxycinnamic acids, followed by strains of Weissella spp., Lactobacillus brevis, Lactobacillus fermentum, and Leuconostoc mesenteroides, for which the MIC values were the same. The highest sensitivity was found for Lactobacillus rossiae strains. During growth in MRS broth, lactic acid bacteria reduced caffeic, p-coumaric, and ferulic acids into dihydrocaffeic, phloretic, and dihydroferulic acids, respectively, or decarboxylated hydroxycinnamic acids into the corresponding vinyl derivatives and then reduced the latter compounds to ethyl compounds. Reductase activities mainly emerged, and the activities of selected strains were further investigated in chemically defined basal medium (CDM) under anaerobic conditions. The end products of carbon metabolism were quantified, as were the levels of intracellular ATP and the NAD(+)/NADH ratio. Electron and carbon balances and theoretical ATP/glucose yields were also estimated. When CDM was supplemented with hydroxycinnamic acids, the synthesis of ethanol decreased and the concentration of acetic acid increased. The levels of these metabolites reflected on the alcohol dehydrogenase and acetate kinase activities. Overall, some biochemical traits distinguished the common metabolism of strictly heterofermentative strains: main reductase activity toward hydroxycinnamic acids, a shift from alcohol dehydrogenase to acetate kinase activities, an increase in the NAD(+)/NADH ratio, and the accumulation of supplementary intracellular ATP. Taken together, the above-described metabolic responses suggest that strictly heterofermentative lactic acid bacteria mainly use hydroxycinnamic acids as external acceptors of electrons.

    In the Netherlands and many other countries research in the field of natural radioactivity is focused on the prevention of radon in the indoor environment. However, also the occurrence of natural radioactivity in the outdoor environment is an interesting subject to be studied. The natural background radiation in the outdoor environment, in particular its variations, hinders the verification of radiation level standards, caused by human activities. An analysis of the data of the Dutch National Monitoring Network for Radioactivity (LMR) provided more insight into those variations. This article is a summary of the authors' thesis on the subject. 5 figs., 8 refs

    Full Text Available We study the Riemann problem for a non-strictly hyperbolic system of conservation laws under the linear approximations of flux functions with three parameters. The approximated system also belongs to the type of triangular systems of conservation laws and this approximation does not change the structure of Riemann solutions to the original system. Furthermore, it is proven that the Riemann solutions to the approximated system converge to the corresponding ones to the original system as the perturbation parameter tends to zero.

    Despite a tremendous interest on molybdenum disulfide as a thinnest direct band gap semiconductor, single step synthesis of a large area purely monolayer MoS{sub 2} film has not yet been reported. Here, we report a CVD route to synthesize a continuous film of strictly monolayer MoS{sub 2} covering an area as large as a few cm{sup 2} on a variety of different substrates without using any seeding material or any elaborate pretreatment of the substrate. This is achieved by allowing the growth to take place in the naturally formed gap between a piece of SiO{sub 2} coated Si wafer and the substrate, when the latter is placed on top of the former inside a CVD reactor. We propose a qualitative model to explain why the MoS{sub 2} films are always strictly monolayer in this method. The photoluminescence study of these monolayers shows the characteristic excitonic and trionic features associated with monolayer MoS{sub 2}. In addition, a broad defect related luminescence band appears at ∼1.7 eV. As temperature decreases, the intensity of this broad feature increases, while the band edge luminescence reduces.

  15. Adaptive terminal sliding mode control for hypersonic flight vehicles with strictly lower convex function based nonlinear disturbance observer.

    2017-11-01

    In this paper, the altitude and velocity tracking control of a generic hypersonic flight vehicle (HFV) is considered. A novel adaptive terminal sliding mode controller (ATSMC) with strictly lower convex function based nonlinear disturbance observer (SDOB) is proposed for the longitudinal dynamics of HFV in presence of both parametric uncertainties and external disturbances. First, for the sake of enhancing the anti-interference capability, SDOB is presented to estimate and compensate the equivalent disturbances by introducing a strictly lower convex function. Next, the SDOB based ATSMC (SDOB-ATSMC) is proposed to guarantee the system outputs track the reference trajectory. Then, stability of the proposed control scheme is analyzed by the Lyapunov function method. Compared with other HFV control approaches, key novelties of SDOB-ATSMC are that a novel SDOB is proposed and drawn into the (virtual) control laws to compensate the disturbances and that several adaptive laws are used to deal with the differential explosion problem. Finally, it is illustrated by the simulation results that the new method exhibits an excellent robustness and a better disturbance rejection performance than the convention approach.

  17. Dutch word stress as pronounced by Indonesian students

    2009-10-01

    Full Text Available This study focuses on the way in which the Dutch monophthongal vowels are pronounced by Indonesian students. To investigate whether Indonesian students realize the Dutch vowels correctly, especially when they are stressed, I analysed duration and quality of stressed and unstressed Dutch vowels. Measurements were done on the duration and the formant frequencies of the vowels spoken by Indonesian students and by native speakers of Dutch as well. Statistical analysis showed that in general the differences in duration between vowels spoken by the Indonesian students and by the native speakers were not significant. However, the effect of stress on the lengthening of the vowels was stronger for the Indonesian students than for the native speakers. In addition, statistical analysis of the formant frequencies confirmed that the non-native speakers realized the Dutch vowels slightly differently from the Dutch native speakers. The Indonesian students pronounced the stressed vowels more clearly than their unstressed counterparts; yet their vowel diagram is smaller than the vowel diagram of the native speakers.

    Alcohol is largely available for Dutch minors through on-premise secondary supply, which occurs when an adult furnishes an alcoholic drink to a minor in an on-premise outlet. Vendors allowing this secondary supply on their premises are in violation of the Dutch Licensing and Catering Act (legal age limit is 18 years old for the sale and possession of alcohol). Using existing mystery shopping protocols as a standard, our study objective was the development and field testing of a novel procedure, measuring vendors' compliance with secondary supply. Using a newly developed mystery shopping procedure, transfers of alcohol between young adult buyers and minors were staged in 109 Dutch on-premise outlets (cafes and bars) to measure vendors' compliance with secondary supply. In accordance with the Dutch Licensing and Catering Act, 29% of the vendors disallowed the secondary supply of alcohol to minors (32 of 109 attempts). During 40 attempts (of 109 attempts; 37%), the vendor asked for the identification document (ID) of the minor. Compliance after the ID was requested was 80% (32 of 40 attempts). During 8 attempts (20%), the minors were served even after the ID of the minor was requested. Mystery shopping is a suitable methodology for measuring compliance with secondary supply. Results show that alcohol is largely available for Dutch minors through secondary supply. Governments that intend to formulate and evaluate enforcement policies aimed at curbing high alcohol availability for minors are advised to use this novel procedure for monitoring compliance and to use these results for agenda setting and benchmarking.

    The aim of this study was to develop a Dutch language version of the Foot and Ankle Outcome Score (FAOS-DLV) and evaluate its measurement properties according to the definitions of the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). After a standard forward-backward translation procedure, the Dutch version of the FAOS was evaluated for reliability and validity in 110 patients with various hind foot and ankle complaints. Reliability was evaluated by calculation of intraclass correlation coefficients (ICC), Cronbach's alpha for internal consistency, and the smallest detectable change (SDC). Construct validity of the FAOS was assessed by calculation of Spearman's correlation coefficients with similar and dissimilar domains of the SF-36 health survey, American Orthopedic Foot and Ankle Society Ankle and Hindfoot Scale, and visual analogue scales for pain and disability. Dimensionality was tested with confirmatory factor analysis. Reliability of the FAOS-DLV was good. The ICC of the subscales ranged from 0.83 to 0.88. The minimal value of Cronbach's alpha was 0.76. The SDC at individual level ranged from 18 to 21 and at group level between 2.1 and 2.5. Construct validity was supported by confirmation of 85 % of the hypothesized correlations. Unidimensionality of the FAOS-DLV domains was moderate. The Dutch version of the FAOS seems to have acceptable measurement properties. The questionnaire can be used for functional assessment of patients with varying hindfoot and ankle symptoms. It is, however, more suitable for clinical evaluation at group level than for monitoring a specific patient. Diagnostic study, Level I.

    It is well established that personality traits are associated with anxiety and depressive disorders in Western populations, but it is not known whether this is true also for people from non-Western cultures. In this study, we examined whether ethnicity moderates the association between personality dimensions and anxiety or depressive disorders or symptoms. In a random urban population sample, stratified by ethnicity, in Amsterdam, the Netherlands, we interviewed 309 native Dutch subjects, 203 Turkish-Dutch subjects, and 170 Moroccan-Dutch subjects. Dimensions of personality were measured using the NEO Five-Factor Inventory. Anxiety and depressive disorders and symptom levels were assessed with the Composite International Diagnostic Interview and the Symptom Checklist-90-Revised. The association between personality factors and disorders or symptoms of anxiety and depression was very similar in the three ethnic groups: all show the typical profile of high neuroticism and low extraversion, agreeableness, and conscientiousness.

  1. Persistent Identifiers for Dutch cultural heritage institutions

    2016-04-01

    Over the past years, more and more collections belonging to archives, libraries, media, museums, and knowledge institutes are being digitised and made available online. These are exciting times for ALM institutions. They are realising that, in the information society, their collections are goldmines. Unfortunately most heritage institutions in the Netherlands do not yet meet the basic preconditions for long-term availability of their collections. The digital objects often have no long lasting fixed reference yet. URL's and web addresses change. Some digital objects that were referenced in Europeana and other portals can no longer be found. References in scientific articles have a very short life span, which is damaging for scholarly research. In 2015, the Dutch Digital Heritage Network (NDE) has started a two-year work program to co-ordinate existing initiatives in order to improve the (long-term) accessibility of the Dutch digital heritage for a wide range of users, anytime, anyplace. The Digital Heritage Network is a partnership established on the initiative of the Ministry of Education, Culture and Science. The members of the NDE are large, national institutions that strive to professionally preserve and manage digital data, e.g. the National Library, The Netherlands Institute for Sound and Vision, the Netherlands Cultural Heritage Agency, the Royal Netherlands Academy of Arts and Sciences, the National Archive of the Netherlands and the DEN Foundation, and a growing number of associations and individuals both within and outside the heritage sector. By means of three work programmes the goals of the Network should be accomplished and improve the visibility, the usability and the sustainability of digital heritage. Each programme contains of a set of projects. Within the sustainability program a project on creating a model for persistent identifiers is taking place. The main goals of the project are (1) raise awareness among cultural heritage institutions on the

    The risk of dengue transmitted by travellers is known. Methods to estimate the transmission by transfusion (TT) risk from blood donors travelling to risk areas are available, for instance, the European Up-Front Risk Assessment Tool (EUFRAT). This study aimed to validate the estimated risk from travelling donors obtained from EUFRAT. Surveillance data on notified dengue cases in Suriname and the Dutch Caribbean islands (Aruba, Curaçao, St. Maarten, Bonaire, St. Eustatius and Saba) in 2001-2011 was used to calculate local incidence rates. Information on travel and donation behaviour of Dutch donors was collected. With the EUFRAT model, the TT risks from Dutch travelling donors were calculated. Model estimates were compared with the number of infections in Dutch travellers found by laboratory tests in the Netherlands. The expected cumulative number of donors becoming infected during travels to Suriname and the Dutch Caribbean from 2001 to 2011 was estimated at 5 (95% CI, 2-11) and 86 (45-179), respectively. The infection risk inferred from the laboratory-based study was 19 (9-61) and 28 (14-92). Given the independence of the data sources, these estimates are remarkably close. The model estimated that 0·02 (0·001-0·06) and 0·40 (0·01-1·4) recipients would have been infected by these travelling donors. The EUFRAT model provided an estimate close to actual observed number of dengue infections. The dengue TT risk among Dutch travelling donors can be estimated using basic transmission, travel and donation information. The TT risk from Dutch donors travelling to Suriname and the Dutch Caribbean is small. © 2016 International Society of Blood Transfusion.

  5. Performance Analysis of Multi-Dimensional ESPRIT-Type Algorithms for Arbitrary and Strictly Non-Circular Sources With Spatial Smoothing

    Science.gov (United States)

    Steinwandt, Jens; Roemer, Florian; Haardt, Martin; Galdo, Giovanni Del

    2017-05-01

    Spatial smoothing is a widely used preprocessing scheme to improve the performance of high-resolution parameter estimation algorithms in case of coherent signals or if only a small number of snapshots is available. In this paper, we present a first-order performance analysis of the spatially smoothed versions of R-D Standard ESPRIT and R-D Unitary ESPRIT for sources with arbitrary signal constellations as well as R-D NC Standard ESPRIT and R-D NC Unitary ESPRIT for strictly second-order (SO) non-circular (NC) sources. The derived expressions are asymptotic in the effective signal-to-noise ratio (SNR), i.e., the approximations become exact for either high SNRs or a large sample size. Moreover, no assumptions on the noise statistics are required apart from a zero-mean and finite SO moments. We show that both R-D NC ESPRIT-type algorithms with spatial smoothing perform asymptotically identical in the high effective SNR regime. Generally, the performance of spatial smoothing based algorithms depends on the number of subarrays, which is a design parameter and needs to be chosen beforehand. In order to gain more insights into the optimal choice of the number of subarrays, we simplify the derived analytical R-D mean square error (MSE) expressions for the special case of a single source. The obtained MSE expression explicitly depends on the number of subarrays in each dimension, which allows us to analytically find the optimal number of subarrays for spatial smoothing. Based on this result, we additionally derive the maximum asymptotic gain from spatial smoothing and explicitly compute the asymptotic efficiency for this special case. All the analytical results are verified by simulations.

  9. Iterative algorithms for the input and state recovery from the approximate inverse of strictly proper multivariable systems

    Science.gov (United States)

    Chen, Liwen; Xu, Qiang

    2018-02-01

    This paper proposes new iterative algorithms for the unknown input and state recovery from the system outputs using an approximate inverse of the strictly proper linear time-invariant (LTI) multivariable system. One of the unique advantages from previous system inverse algorithms is that the output differentiation is not required. The approximate system inverse is stable due to the systematic optimal design of a dummy feedthrough D matrix in the state-space model via the feedback stabilization. The optimal design procedure avoids trial and error to identify such a D matrix which saves tremendous amount of efforts. From the derived and proved convergence criteria, such an optimal D matrix also guarantees the convergence of algorithms. Illustrative examples show significant improvement of the reference input signal tracking by the algorithms and optimal D design over non-iterative counterparts on controllable or stabilizable LTI systems, respectively. Case studies of two Boeing-767 aircraft aerodynamic models further demonstrate the capability of the proposed methods.

  10. Globally Stable Adaptive Backstepping Neural Network Control for Uncertain Strict-Feedback Systems With Tracking Accuracy Known a Priori.

    2015-09-01

    This paper addresses the problem of globally stable direct adaptive backstepping neural network (NN) tracking control design for a class of uncertain strict-feedback systems under the assumption that the accuracy of the ultimate tracking error is given a priori. In contrast to the classical adaptive backstepping NN control schemes, this paper analyzes the convergence of the tracking error using Barbalat's Lemma via some nonnegative functions rather than the positive-definite Lyapunov functions. Thus, the accuracy of the ultimate tracking error can be determined and adjusted accurately a priori, and the closed-loop system is guaranteed to be globally uniformly ultimately bounded. The main technical novelty is to construct three new n th-order continuously differentiable functions, which are used to design the control law, the virtual control variables, and the adaptive laws. Finally, two simulation examples are given to illustrate the effectiveness and advantages of the proposed control method.

    This paper investigates the online recorded data-based composite neural control of uncertain strict-feedback systems using the backstepping framework. In each step of the virtual control design, neural network (NN) is employed for uncertainty approximation. In previous works, most designs are directly toward system stability ignoring the fact how the NN is working as an approximator. In this paper, to enhance the learning ability, a novel prediction error signal is constructed to provide additional correction information for NN weight update using online recorded data. In this way, the neural approximation precision is highly improved, and the convergence speed can be faster. Furthermore, the sliding mode differentiator is employed to approximate the derivative of the virtual control signal, and thus, the complex analysis of the backstepping design can be avoided. The closed-loop stability is rigorously established, and the boundedness of the tracking error can be guaranteed. Through simulation of hypersonic flight dynamics, the proposed approach exhibits better tracking performance.

    This paper studies both indirect and direct global neural control of strict-feedback systems in the presence of unknown dynamics, using the dynamic surface control (DSC) technique in a novel manner. A new switching mechanism is designed to combine an adaptive neural controller in the neural approximation domain, together with the robust controller that pulls the transient states back into the neural approximation domain from the outside. In comparison with the conventional control techniques, which could only achieve semiglobally uniformly ultimately bounded stability, the proposed control scheme guarantees all the signals in the closed-loop system are globally uniformly ultimately bounded, such that the conventional constraints on initial conditions of the neural control system can be relaxed. The simulation studies of hypersonic flight vehicle (HFV) are performed to demonstrate the effectiveness of the proposed global neural DSC design.

    The paper considers the stabilization issue of linear continuous singular systems by dealing with strict linear matrix inequalities (LMIs) without invoking equality constraint and proposes a complete and effective solved LMIs formulation. The criterion is necessary and sufficient condition and can be directly solved the feasible solutions with LMI toolbox and is much more tractable and reliable in numerical simulation than existing results, which involve positive semi-definite LMIs with equality constraints. The most important property of the criterion proposed in the paper is that it can overcome the drawbacks of the invalidity caused by the singularity of Ω=PE T +SQ for stabilization of singular systems. Two counterexamples are presented to avoid the disadvantages of the existing condition of stabilization of continuous singular systems. Copyright © 2017 ISA. Published by Elsevier Ltd.

    An effective catheter ablation strategy, beyond pulmonary vein isolation (PVI), for persistent atrial fibrillation (AF) is necessary. Pulmonary vein (PV)-reconduction also causes recurrent atrial tachyarrhythmias. The effect of the PVI and additional effect of a superior vena cava (SVC) isolation (SVCI) was strictly evaluated. Seventy consecutive patients with persistent AF who underwent a strict sequential ablation strategy targeting the PVs and SVC were included in this study. The initial ablation strategy was a circumferential PVI. A segmental SVCI was only applied as a repeat procedure when patients demonstrated no PV-reconduction. After the initial procedure, persistent AF was suppressed in 39 of 70 (55.7%) patients during a median follow-up of 32 months. After multiple procedures, persistent AF was suppressed in 46 (65.7%) and 52 (74.3%) patients after receiving the PVI alone and PVI plus SVCI strategies, respectively. In 6 of 15 (40.0%) patients with persistent AF resistant to PVI, persistent AF was suppressed. The persistent AF duration independently predicted persistent AF recurrences after multiple PVI alone procedures [HR: 1.012 (95% confidence interval: 1.006-1.018); pstrategies [HR: 1.018 (95% confidence interval: 1.011-1.025); pstrategies, respectively. The outcomes of the PVI plus SVCI strategy were favorable for patients with shorter persistent AF durations. The initial SVCI had the additional effect of maintaining sinus rhythm in some patients with persistent AF resistant to PVI. Copyright © 2018 Japanese College of Cardiology.

    The use of working hours outside the standard ‘9 to 5’ working pattern increased between 2000 and 2002 in the Netherlands, but has stabilised since then. About three quarters of Dutch employees at least occasionally work overtime. Shift work, evening or night work, and weekend work are most often

    The lack of a uniform costing methodology is often considered a weakness of economic evaluations that hinders the interpretation and comparison of studies. Standardisation is therefore an important topic within the methodology of economic evaluations and in national guidelines that formulate the formal requirements for studies to be considered when deciding on the reimbursement of new medical therapies. Recently, the Dutch Manual for Costing: Methods and Standard Costs for Economic Evaluations in Health Care (further referred to as "the manual") has been published, in addition to the Dutch guidelines for pharmacoeconomic research. The objectives of this article are to describe the main content of the manual and to discuss some key issues of the manual in relation to the standardisation of costs. The manual introduces a six-step procedure for costing. These steps concern: the scope of the study;the choice of cost categories;the identification of units;the measurement of resource use;the monetary valuation of units; andthe calculation of unit costs. Each step consists of a number of choices and these together define the approach taken. In addition to a description of the costing process, five key issues regarding the standardisation of costs are distinguished. These are the use of basic principles, methods for measurement and valuation, standard costs (average prices of healthcare services), standard values (values that can be used within unit cost calculations), and the reporting of outcomes. The use of the basic principles, standard values and minimal requirements for reporting outcomes, as defined in the manual, are obligatory in studies that support submissions to acquire reimbursement for new pharmaceuticals. Whether to use standard costs, and the choice of a particular method to measure or value costs, is left mainly to the investigator, depending on the specific study setting. In conclusion, several instruments are available to increase standardisation in

    The purpose of this study was to validate the Parental Burnout Inventory (PBI) in a Dutch sample of working parents. The Dutch version of the PBI and questionnaires about work were administered to 627 working parents, with at least one child living at home. We investigated whether the tri-dimensional structure of the PBI held in a sample of male and female employed parents. Furthermore, we examined the relationships between PBI and the constructs work-related burnout, depressive mood, parenting stress and work-family conflict, which we assessed with widely used and validated instruments, i.e., emotional exhaustion [a subscale of the Dutch version of Maslach's Burnout Inventory], a Dutch Parental Stress Questionnaire and Work-Family Conflict. The results support the validity of a tri-dimensional parental burnout syndrome, including exhaustion, distancing and inefficacy. Low to moderate correlations between parents' burnout symptoms and professional exhaustion, parenting stress, depressive complaints and work-family conflict experiences were found, suggesting that the concept of PBI differs significantly from the concepts of job burnout, depression and stress, respectively. The current study confirms that some parents are extremely exhausted by their parental role. However, the number of Dutch employees reporting extreme parental burnout is rather low.
