    The revised Dutch College of General Practitioners (Nederlands Huisartsen Genootschap [NHG]) guideline 'Deep-vein thrombosis and pulmonary embolus' includes recommendations for the treatment of patients with deep-vein thrombosis (DVT) and thrombophlebitis, and for the exclusion of pulmonary embolism (PE). The general practitioner (GP) can exclude the presence of DVT or PE in some patients by using a decision rule and a D-dimer test. When using D-dimer test as a point-of-care test, meticulous care is essential during the test procedure and storage of blood. The GP can treat many patients with DVT; the NHG guideline does not advise use of direct oral anticoagulants. In the case of an isolated DVT in the calf, treatment with anticoagulants or ultrasound follow-up can be chosen in consultation with the patient or on the basis of regional agreements. In the case of patients with superficial thrombophlebitis, a wait-and-see approach is usually sufficient.

    In order to establish the reach, the reading frequency and the appreciation of the Nederlands Tijdschrift voor Geneeskunde, a telephone inquiry was conducted among a random sample of specialists, general practitioners, registrars and pharmacists in the Netherlands. The response amounted to 81.5% (n = 1515). Of the respondents, 94% received the Journal, and two-thirds read it every week. Eight out of ten saved the Journal, five even all volumes. The reading frequency varied greatly from one section to another. Of those who read the Journal at all, 74% always or often read the clinical lesson and 6% the original articles. Although, due to increasing specialization (in width and in depth), it is becoming increasingly difficult to satisfy all readers, the appreciation of the articles is high.

    Literature references contain a considerable number of inaccuracies, both in citations and in quotations. We investigated the accuracy of quotations and references in Nederlands Tijdschrift voor Geneeskunde. We checked at random 100 references of articles presented for publication during a period of 4 weeks using Index Medicus. The citation and quotation of another 100 references (50 with a reading list of less than 13, and 50 with a reading list of more than 24 articles) of published original articles were checked, using the original article. In the references of articles presented for publication 70% contained one or more inaccuracies. In the published articles 31% was not completely correct. In 5% these errors prevented immediate identification of the cited article. In one of every three articles a citation error was made: 5 trivial errors, 16 slightly misleading and 12 seriously misleading errors were found. We could not find a relation between the number of citation errors and the length of the reading list. The original source was not cited in 8 articles. Our conclusion is that the number of inaccuracies, in references as well as in citations, is high; authors should check this part of their articles more carefully. Notably the use of multiple references after a sentence with a number of statements is to be avoided.

    'Lessons of the Week' have been published in Nederlands Tijdschrift voor Geneeskunde since 1928. They consist of a clinical patient demonstration on paper but with the structure and the wording appropriate for a college theater. These lessons are read by three quarters of the journal's readership. They are usually written by senior clinicians.

    Original articles offer the reader of the Nederlands Tijdschrift voor Geneeskunde information about Dutch scientific research. These readers are selective but appreciative. The emphasis has shifted in the last 40 years from case histories, introduction of new techniques, literature studies and opinions, to qualitatively and methodologically adequate numerical studies, with strictly arranged presentation. The numbers of patients per study have increased substantially, and statistical processing has grown more extensive. Cost-benefit analyses appeared. The number of prospective studies remained constant.

    From the 1st of July 2008 the Dutch smoking ban for public spaces will be extended to hotels, restaurants and bars. The ban is a result of a 2003 Health Council report in which it was concluded that the annual incidence of deaths due to passive smoking is considerable. Based on these numbers, smoking in public spaces is prohibited since 2004. In a society where smoking in public spaces is prohibited, the harm of passive smoking will decrease. In this issue of The Nederlands Tijdschrit voor Geneeskunde (Dutch Journal of Medicine) a number of articles are dedicated to the subject of smoking.

    The Nederlands Tijdschrift voor Geneeskunde has been publishing medical science in Dutch for 140 years. To bridge the gap between the specialist science and the general medical reader several sections in the accepted papers have to be clarified, simplified and shortened by post acceptance editing. The style and language of the authors is treated with respect. Changes are made if the article does not comply with internationally accepted rules on scientific reporting, if the article can not be understood using currently authoritative general and medical books of reference, and if its language does not comply with generally accepted Dutch rules for grammar and spelling.

    1997-01-04

    The Nederlands Tijdschrift voor Geneeskunde was founded in 1856 when five of the nine medical journal in the Netherlands decided to join hands and launch a new medical weekly (in Dutch). About 800 manuscripts are now submitted each year, most of which are peer reviewed before acceptance. The editorial board consists of about twenty medical specialists who have agreed to carry out the bulk of the peer review for a period of three years each. After retirement from the editorial board, they are a lifelong member of the Association of the Dutch Journal of Medicine. After acceptance, articles are thoroughly scientifically and linguistically edited to ensure that the general medical readership will understand them. About 50% of the accepted papers are published within twenty weeks. In the near future the journal pages will have more illustrations and more coloured ones, educative panels, and a digest of Dutch research published in international journals.

    At the end of 2005, a new edition of the Woordenlijst Nederlandse taal (List of words in the Dutch language, also referred to as the Green booklet) appeared with a few adjustments to the spelling changes implemented in 1995. These adjustments led to considerable excitement in the media. The new spelling rules and the new List of words have consequences for the style of the articles in the Nederlands Tijdschrift voor Geneeskunde (NTvG). The most important changes concern the use of lower case in combinations containing a proper name (for example, 'watson-jones-artrodese' instead of 'Watson-Jones-artrodese'). Certain abbreviations are also to be written in lower case from now on ('ecg' and 'hiv'). Finally, the rule for the intermediate 'n' in Dutch words such as 'paarde(n)bloem' has been reversed: one is now to write 'paarden-bloem' instead of' 'paardebloem'. Thanks to the greater availability of electronic spelling control programmes and the availability of all previous volumes of the NTvG in digital form, it will be easier for the authors of medico-scientific articles in the Dutch language to achieve a uniform spelling. The new rules were implemented officially on 1 August 2006.

    2001-01-06

    Original articles are the backbone of this journal, as with any scientific journal. The Nederlands Tijdschrift voor Geneeskunde stimulates submissions in this category of articles by offering an annual prize for young authors. On the other hand 30-40% of original articles has to be turned away by the editors, because of vital short-comings. The subject matter can be unsuitable, such as details about organisation of health care or a highly specialised topic. More often the methods are at fault. Common problems are: lack of a proper research question, result of medical or surgical treatment without a control group, use of a questionnaire, poor validity because of bias in selection of patients, circular reasoning in the assessment of a diagnostic test, or an inappropriate measure of outcome. We urge prospective authors to seek advice from a clinical epidemiologist or at least from a colleague with experience in clinical research before embarking on a clinical study. If such help is difficult to obtain the editors are prepared to act as intermediary between authors and methodological experts.

    1991-05-11

    To deduce recommendations for authors which decrease the rejection probability we investigated retrospectively which reasons were mentioned in 1990 by the editorial board of the 'Nederlands Tijdschrift voor Geneeskunde' when it rejected original articles, reviews, clinical lessons and case reports, and whether length of the article, professional status of the first author, most relevant specialism and origin of the article influenced the rejection probability. Out of 547 articles 38% (208) were rejected; case reports were rejected most often (49%), reviews least often (33%). Peer review of original articles was the most thorough, of case studies the least. The most frequent reason for rejection in all categories was 'substantial shortcomings', particularly in the original articles (80%). Rejection of clinical lessons and case studies was relatively often due to criteria concerning the clinical message. Both rejected and accepted articles on average exceeded the length limit. Professional status and specialism were associated with a difference in rejection probability (chi 2, p less than 0.05). Specialists had the lowest rejection probability (31%). Nonspecialists benefited from specialist supervision. Articles originating from non-academic institutions were more often rejected than articles from academic centres. We advise authors to judge their articles by means of the criteria mentioned. Consultation of (methodological) experts, literature data bases, and (or) the editorial board can improve their chances. Non-specialists can benefit from the experience and expertise of specialists. In general, scientific attitude and willingness to alter the article according to editorial advice appear to have beneficial results.

    2007-02-17

    The Nederlands Tijdschrift voor Geneeskunde (NTvG [Dutch Journal of Medicine]) celebrates its 150th anniversary this year. J. van der Meer and S.van 't Hofare the editors of a jubilee book issued to mark the occasion. Two earlier books, issued for the 50th and 100th anniversary of the journal, focused primarily on the history of the association of editors which publishes the NTvG. Unlike these books, a large portion of the current jubilee book is devoted to the history of medicine in the Netherlands in the last 50 years. Of greater importance is that the authors reflect on the relationship between the NTvG, the medical profession and society at large. This relationship has intensified since the 1960's. The NTvG has accomplished its goal of being a general medical journal, but lacks 'the voice of the patient' and editorial comments on current social issues. With respect to the physician-patient relationship, the Netherlands has succeeded more than other countries in diminishing the gap between these two partners. The way the Dutch have dealt with the issue of euthanasia is a clear example. But as to the role of the physician in society, the loss of position and authority, increasing professionalism and specialisation and reluctance to engage in social and ethical debate for fear of losing impartiality have caused the medical profession to assume a marginal position in society, even with respect to its own needs as a group of professionals. At present, there is a clear need for physician citizenship that engages in a broad spectrum of social responsibilities in a professional context.

    During the eighties of the 19th century several physical education teachers who were engaged in physical therapy activities, so called 'heilgynasten', believed that only a solid organization of serious, educated and well-trained heilgymnasten could bring about a positive change in the situation at hand in the field of physical therapy. On September 1st 1889 the 'Genootschap ter beoefening van de Heilgymnastiek in Nederland' ('Society for practising heilgymnastiek in the Netherlands') was founded. The main aim of its members was to establish a state-exam, a public trainingschool as well as to ensure proper legislation for this 'new' profession. In this paper the focus of attention is on the founding of the 'Genootschap' and the reactions it provoked from organizations and practitioners in the fields of physical education and medicine during the first years of its existance. One could say that at first the 'Genootschap' was tolerated. Several well-known Dutch physicians joined the 'Genootschap' as 'extraordinary-member'. Very soon however, some physicians came to see the activities of this organization as a threat to the process of differentiation and specialization in the field of orthopaedic surgery that had just began. They emphasized that the 'heilgymnasten' who worked relatively independent from physicians in the field of physical therapy had no legal status; in fact they argued that these practitioners were actually breaking the law. A solution to these problems was sought through law-suits against 'heilgymnasten' to ensure that they would only practise physical therapy under supervision of physicians. In a next article the plight of one of the Dutch 'heilgymnasten', Hendrik Soeter, who can be considered as a 'victim' of this strategy, will be discussed in more detail. The Dutch 'heilgymnasten' did finally gain a legal status for their profession, but they had to wait for that untill more than fifty years after the foundation of the 'Genootschap'.

    PubMed

    van der Hoogte, Arjo Roersch; Pieters, Toine

    2010-01-01

    In this article we explore the historical development of drug advertisements for psychotropic drugs in the leading Dutch medical journal from 1900 to 1940. The advertisements for hypnotics and sedatives, in The Nederlands Tijdschrift voor Geneeskunde (Dutch medical journal) reflected the changes in the vocabulary and image promoted by the pharmaceutical companies. In the first two decades, the advertisements were sober and to the point, and included the trademark, company name, molecular formula and therapeutic properties of the medication. The emphasis was on creating a scientific image of reliable symptom control for the therapeutic drug. In doing so, the ethical drug companies tried (successfully) to distinguish themselves from the producers of patent medicines. Once scientific credibility was established, the form and content of the advertisements changed significantly. In the late 1920s and 1930s drug companies embraced modern advertising techniques, developing a figurative language to address the changing beliefs and practices of Dutch physicians. Instead of promoting therapeutic drugs as safe and scientific, the emphasis was on their effectiveness in comparison to similar drugs. In the process, scientific information was reduced to an indispensable standardized minimum, whereby therapeutic drugs were advertised according to the latest pharmacological taxonomy rather than molecular formulas. The image-making of 'ethical marketing' began during the interwar years when marketers applied modern advertising techniques and infotainment strategies. The scanty black and white informational bulletins transitioned into colourful advertisements. The pharmaceutical companies employed the same medical language as used by physicians, so that one word or image in an advertisement would suffice for the physician to recognize a drug and its therapeutic properties. These developments show the changing relationship between the modern ethical pharmaceutical industry and Dutch

    The editors of this journal have decided that the number of authors of original articles and guidelines may in the future exceed the current limit of six. For other articles, e.g. clinical lessons, case reports and review articles, the limit remains. Contributions to the series 'Diagnostic image' will have a maximum of two authors. For a number of years now, authors have been asked to provide specific information as to the nature of their contribution to the article that carries their name. This enables the editors and the reviewers to assess whether the criteria for authorship have been met. Information on authors' contributions will not be printed alongside the articles but will be kept available to readers for three months after the article has appeared.

    NASA Astrophysics Data System (ADS)

    van der Schoor, W. J.

    2012-04-01

    Most experiment stations originated from the cooperation between entrepreneurs and the government. From the 1890s onwards, the government, together with the well organised colonial entrepreneurs, established research departments for several plantation crops at the Botanical Gardens at Buitenzorg (now Bogor), that eventually became independent experiment stations in the first decades of the twentieth century. By the 1920s, the ‘proefstationswezen’ (experiment station system) numbered some fifteen private experiment stations or sub-stations. After the war, the private experiment stations together with the government experiment stations at Buitenzorg were to provide the backbone of Indonesian agricultural science. Dutch biologists in particular, made a striking plea for pursuing the natural sciences in the tropical colonies. First, they pointed out the scientific importance of the tropics. Secondly, they stressed the role of the natural sciences, in particular biology, as a natural ally of colonial agriculture. Pure science was seen as a leading force for technical and social progress. The third motive was the cultural value of science for the Netherlands and its colonies. The cultivation of science in the colonies gave international prestige and strengthened self-confidence in the imperial struggle around 1900. Science had a civilising effect; scientific research, however, was to remain in the hands of western, colonial scientists. From the 1880s and 1890s onward, the experiment stations in the Indies were characterised by their strategic aims and scientific orientation. Up to 1910, the ‘academic’ views of biologists like Treub and Went concerning science and practice were predominant, and research was considered to be the central aim. From 1910 onwards, advice became more central and special extension services were established at the experiment stations. Due to diverging views of science, tasks and aims became a battlefield for discussions in the next decades. In the background of these debates were the rise of Wageningen Agricultural College, the rise and institutionalisation of applied agricultural sciences and the increasing competition between Wageningen and university trained scientist. Genetics and breeding in particular were at the core of the research programmes. The practical aim of the breeding work, however, did not leave too much opportunity for more fundamental investigations. The impetus for pure research came from individual researchers. In tobacco and sugar cane breeding, new scientific theories provided inspiration, but to a large extent the practical breeding work built on nineteenth-century breeding techniques. In many respects, plant breeding and university genetics became separate disciplines. Circa one in six Dutch biologist worked for at least some time in the colony. The colonial experiment stations instilled a practical and pragmatic attitude to Dutch science into quite a number of biologists. Besides, the experiment stations system provided Dutch biologists with an extensive network and international contacts with fellow scientists, entrepreneurs and captains of industry. The scientific nationalism of Treub and Went, the bloom of the experiment stations and the ambitions of the Indies colonial elite did not result in the establishment of an independent, ‘Indische’ scientific community. Essentially, the Dutch East Indies were an exploitation province of Dutch science

  16. Documenting Living Monuments in Indonesia: Methodology for Sustainable Utility

    NASA Astrophysics Data System (ADS)

    Suryaningsih, F.; Purwestri, N.

    2013-07-01

    The systematic documentation of cultural heritage in Indonesia has been developed after the establishment of Bataviaasch Genootschap van Kunsten en Wetenschappen (1778) and De Oudheidkundige Dienst (1913) by the Netherlands Indies government. After Indonesian independent, the tasks of cultural heritage documentation take over by The Ministry of Culture (now become The Ministry of Education of Culture) with focus on the ancient and classical heritage, so called dead monument. The needed of comprehensive documentation data regarding cultural heritage become significant issues since the government and private sector pay attention to the preservation of heritage building in the urban site, so called living monument. The archives of original drawing plan many times do not fit with the existing condition, while the conservation plan demands a document such as built drawing plan to work on. The technology, methodology and system to provide such comprehensive document of heritage building and site become important, to produce good conservation plan and heritage building regular maintenance. It means the products will have a sustainable and various utility values. Since 1994, Documentation Centre for Architecture - Indonesia (PDA), has established to meet the needs of a comprehensive data of heritage building (living monuments), to utilized as basic document for conservation planning. Not only provide document of the digital drawing such site plan, plan, elevation, section and details of architecture elements, but also document of historic research, material analysis and completed with diagnosis and mapping of building damages. This manuscript is about PDA field experience, working in this subject issue

  17. "A bare outpost of learned European culture on the edge of the jungles of Java": Johan Maurits Mohr (1716-1775) and the emergence of instrumental and institutional science in Dutch Colonial Indonesia

    2004-03-01

    The transits of Venus in 1761 and 1769 appear to mark the starting point of instrumental science in the Dutch East Indies (now Indonesia). This essay examines the conditions that triggered and constituted instrumental and institutional science on Indonesian soil in the late eighteenth century. In 1765 the Reverend J. M. Mohr, whose wife had received a large inheritance, undertook to build a fully equipped private observatory in Batavia (now Jakarta). There he made several major astronomical and meteorological observations. Mohr's initiative inspired other Europeans living on Java around 1770 to start a scientific movement. Because of the lack of governmental and other support, it was not until 1778 that this offspring of the Dutch-Indonesian Enlightenment became a reality. The Bataviaasch Genootschap van Kunsten en Wetenschappen tried from the beginning to put into effect the program Mohr had outlined. The members even bought his instruments from his widow, intending to continue his measurements. For a number of reasons, however, this instrumental program was more than the society could support. Around 1790 instrumental science in the former Dutch East Indies came to a standstill, not to be resumed for several decades.

    1993-01-01

    Radiation thermometry is applied in the measurement of temperature where direct contact with the object is impossible, such as in the case of very high temperatures or moving bodies. Important industrial applications are metal, glass, ceramics and plastics and, latterly, semiconductor technology. Recent developments, such as multi-wavelength pyrometry, have motivated the Nederlands Meetinstituut and two Russian institutes, Energotechnica and Symco Association, to organize this workshop. Specialists from Russia, the USA, the UK, Germany and the Netherlands will present state-of-the-art practical applications in radiation thermometry. The workshop will be held on 24 and 25 June 1993 in the "Leeuwenhorst" Congress Centre, Noordwijkerhout, the Netherlands. Information on the technical contents of the programme can be obtained from Dr P Bloembergen, Tel. +31(15) 691 660.

  16. Algorithms for radio interference detection and removal

    Offringa, Anne René

    2012-06-01

    Tijdens dit onderzoek hebben we gekeken naar de invloed van storing door menselijke apparatuur op radioastronomie. Radiosterrenwachten zoals Westerbork kunnen de hemel met een enorme gevoeligheid en resolutie in kaart brengen. Vaak bestaan zulke sterrenwachten uit een aantal grote schotelantennes. Echter, nieuwe technologische ontwikkelingen hebben ervoor gezorgd dat op lage frequenties vele kleine antennes efficiënt gecombineerd kunnen worden tot een grote schoteltelescoop. LOFAR is een nieuwe, deels-Nederlandse supertelescoop die gebruik maakt van dit principe. Deze telescoop bestaat uit tientallen velden gevuld met vele antennetjes, verspreid over Nederland en omringende landen. Het centrum van LOFAR bevindt zich in de buurt van het Drentse dorp Exloo. Radiotelescopen worden meestal in zeer afgelegen gebieden geplaatst, omdat menselijke apparatuur storing veroorzaakt. Het bouwen van een radiotelescoop op afgelegen locaties is echter niet goedkoop. LOFAR is een nieuwe weg ingeslagen en bevat antennevelden op diverse plaatsen in ons druk bevolkte land. Een belangrijke vraag was daardoor of de storing van menselijke apparatuur niet schadelijk zou zijn voor LOFAR-observaties. In dit proefschrift beantwoorden we deze vraag. We hebben volledig geautomatiseerde technieken ontworpen om storing te verwijderen. Met deze nieuwe technieken weten we de storing op zeer accurate wijze te scheiden van het hemelsignaal. We analyseren de gefilterde data en concluderen dat, na toepassing van deze technieken, we in staat zijn om zeer gevoelige hemelkaarten te maken met LOFAR. Daarmee lijkt het dus een goede keuze geweest te zijn om LOFAR in Nederland te bouwen.

    This article is the introduction to a new series in the Nederlands Tijdschrift voor Geneeskunde about the value of physical examination. Associated with this series, on the website (www.ntvg.nl) there are chapters of the new textbook on physical examination and films about carrying out physical examinations. Although physical examination is an essential part of the diagnostic process, often little attention is paid to the correct execution of the examination and there is insufficient knowledge of the value of the findings. The diagnostic process usually involves analysing all the information from the patient's history and a physical examination. However, research has only been done on the value of specific tests and even that is very limited. The most important measure we use for the results of a physical examination is the likelihood ratio, which shows how the likelihood of presence or absence of a disease changes depending on the examination results.

    In the first half of 2005, Nederlands Meetinstituut Van Swinden Laboratorium B.V. (NMi VSL) redesigned their facilities for radiation thermometry in a new laboratory building and an opportunity arose to implement new measurement methods. The new facility is used for ITS-90 realization and dissemination in the temperature range from - 50 °C to 3,000 °C. A study was performed to compare a silver-point realization with a fixed-point blackbody radiator (FP-BBR) to a sodium heat-pipe blackbody radiator (HP-BBR) traceable via a HTSPRT to a contact thermometry silver point. It was found that the fixed-point realization transfer to the sodium heat pipe results in an uncertainty from 0.2 K to 2.4 K for the ITS-90 over the temperature range from 961.78 °C to 3,000 °C.

    Ground-based FTIR and millimeter wave measurements of the Institute of Meteorology and Climate Research (IMK), Forschungszentrum Karlsruhe, and the Swedish Institute of Space Physics (IRF) are used for validation of SCIAMACHY ozone measurements. FTIR and millimeter wave measurements used for this study were routinely carried out between 2002 and 2004 at IRF at Kiruna, Sweden. In addition IMK carried out millimeter wave measurements on Mount Zugspitze in the Alps in 2003. SCIAMACHY level 2 NRT-products of 2002 are only validated by FTIR data since millimeter wave observations started in late 2002 when SCIAMACHY data were unavailable. For the years 2003 and early 2004 total ozone column abundances retrieved with the TOSOMI algorithm of the Royal Netherlands Meteorological Institute (Koninklijk Nederlands Meteorologisch Instituut, KNMI) are validated by the FTIR and microwave measurements. Finally, ozone limb profiles between July and November 2002 taken from the current SCIA Level 2 Off-Line masterset are validated by the FTIR measurements at Kiruna

    2003-07-01

    The theoretical criterion defining the threshold pulse energy and beam intensity required for melt ejection is proposed. The results of numerical simulation present dependencies of the threshold pulse energy and beam intensity as functions of laser pulse duration and beam radius. The experimental verification of proposed criterion is described and the comparison of theoretical predictions and measurements is presented. The criterion is applied for simulation of laser drilling metal foil with thickness in the range 25 μm - 125 μm using laser beam with 12 μm beam radius and pulse durations 10 ns and 100 ns. The computational results are used to interpret the results of experimental study of laser drilling of 125 μm aluminum foil using a single mode beam of a XeCl laser performed at the Nederlands Centrum voor Laser Research (NCLR) and the University of Twente. Additional results on Nd:YAG spot welds in pure Ni are also presented.

    We will report on the progress of our project to realize a traceable Scanning Probe Microscope at the Van Swinden Laboratorium of the Nederlands Meetinstituut in the Netherlands. The traceable Atomic Force Microscope (AFM) is constructed from a separate AFM head, a 3D translation stage and an accurate 3D laser interferometer system. Nanometer uncertainty can be maintained in the entire scanning volume of 100 μm × 100 μm × 20 μm. Apart from providing direct traceability to the SI unit of length, the coordinates provided by the laser interferometer are also used in a closed loop position feedback controller to realize accurate positioning at arbitrary locations within the volume provided by the translation stage. In this paper we will emphasize the development of the control system.

    1994-02-01

    Data obtained by direct observation of 112 3-6-year-old normal children and 31 children with a pervasive developmental disorder aged 3-6 were used to construct behaviour scales by means of simultaneous component analysis. This is a technique for finding behaviour clusters (components) common to different groups by weighting the variables such that the resulting components maximize variance accounted for when summed over the groups (Milsap & Meredith, 1988, Psychometrika, 53, 123-134; Berge & Kiers, 1990, Nederlands Tijdschrift voor de Psychologie, 45, 221-226). An evaluation of the component structure that was found is given for both groups. Results show uncorrelated components for the normal group, while some of the same components are intercorrelated in the clinical group. Scales were constructed which are shown to have discriminative value with respect to subgroups within the group of patients.

  6. The hovercraft environment.

    PubMed

    Lovesey, E J

    1970-06-01

    In just over a decade the hovercraft has progressed from first prototype to a successful commercial form of transport which also has the ability to penetrate many environments hitherto virtually inaccessible to manned vehicles. Comparison with rival short range vehicles such as the helicopter and hydrofoil show that the hovercraft has become one of the most versatile forms of transport available. This versatility and ability to operate in unusual or extreme environments has been accompanied by the problems of control and of protection of the occupants of the hovercraft from the hazards associated with these environments. Several of these problems are discussed, together with their possible solutions. This article is based on a paper given to the Nederlands Vereniging Voor Ergonomie/Ergonomics Research Society joint conference at Noordwijk in Holland, 11-13 June, 1969.

    2013-06-01

    The Triangle Orientation Discrimination (TOD) test method was applied to characterize thermal and visual range performance of the Gatekeeper Electro Optical Security System. Gatekeeper developed by Thales Nederland BV, is currently in use with the Royal Netherlands Navy. The system houses uncooled infrared and colour TV cameras providing up to 360° view in azimuth. The images displayed to the operator are automatically optimized based on the scene intensity distribution. Because of this built-in scene-based optimization, proper measurement of the system requires careful surround illumination of the TOD setup over a large part of the camera Field Of View. The tests provided very accurate threshold estimates with relatively small observer differences. The resulting TOD curves that characterize the sensor system in terms of acuity and contrast sensitivity can be used as input to a Target Acquisition model to predict range performance for operational scenarios.

    The Paul-Ehrlich-Institut (PEI), the Nederlands Vaccin Instituut (NVI) and the European Directorate for the Quality of Medicines & HealthCare (EDQM) organised the international scientific workshop "Animal free Detection of Pertussis Toxin in Vaccines--Alternatives to the Histamine Sensitisation Test" at the PEI in Langen (Germany) on 09-10 June 2011. Twenty-seven experts (regulators, representatives from national control laboratories, vaccine manufacturers and academia) from 7 countries participated in this workshop. The meeting was triggered by the lack of satisfaction with the current safety testing for acellular pertussis vaccines, the "Histamine Sensitisation Test" (HIST) in mice, and the growing attention for the alternatives under development. The workshop objectives were: a) to review the current status of available alternative methods, b) to discuss the sensitivity that an alternative test needs, c) to plan experiments that allow for comparison of the alternative tests. The results of the workshop are summarised in this meeting report.

  9. The Scars of Childhood Adversity: Minor Stress Sensitivity and Depressive Symptoms in Remitted Recurrently Depressed Adult Patients

    Background Childhood adversity may lead to depressive relapse through its long-lasting influence on stress sensitivity. In line with the stress sensitization hypothesis, minor (daily) stress is associated with depressive relapse. Therefore, we examine the impact of childhood adversity on daily stress and its predictive value on prospectively assessed depressive symptoms in recurrently depressed patients. Method Daily stress was assessed in recurrently depressed adult patients, enrolled into two randomized trials while remitted. The reported intensity and frequency of dependent and independent daily stress was assessed at baseline. Independent stress is externally generated, for example an accident happening to a friend, while dependent stress is internally generated, for example getting into a fight with a neighbor. Hierarchical regression analyses were performed with childhood adversity, independent and dependent daily stress as predictor variables of prospectively measured depressive symptoms after three months of follow-up (n = 138). Results We found that childhood adversity was not significantly associated with a higher frequency and intensity of daily stress. The intensity of both independent and dependent daily stress was predictive of depressive symptom levels at follow-up (unadjusted models respectively: B = 0.47, t = 2.05, p = 0.041, 95% CI = 0.02–0.92; B = 0.29, t = 2.20, p = 0.028, 95% CI = 0.03–0.55). No associations were found between childhood adversity and depressive symptoms at follow-up. Conclusion No evidence was found supporting stress sensitization due to the experience of childhood adversity in this recurrently depressed but remitted patient group. Nevertheless, our research indicates that daily stress might be a target for preventive treatment.

    The process of forensic facial analysis may be founded on several scientific techniques and imaging modalities, such as digital signal processing, photogrammetry and craniofacial anthropometry. However, one of the main limitations in this analysis is the comparison of images acquired with different angles of incidence. The present study aimed to explore a potential approach for the correction of the planar perspective projection (PPP) in geometric structures traced from the human face. A technique for the correction of the PPP was calibrated within photographs of two geometric structures obtained with angles of incidence distorted in 80°, 60° and 45°. The technique was performed using ImageJ(®) 1.46r (National Institutes of Health, Bethesda, Maryland). The corrected images were compared with photographs of the same object obtained in 90° (reference). In a second step, the technique was validated in a digital human face created using MakeHuman(®) 1.0.2 (Free Software Foundation, Massachusetts, EUA) and Blender(®) 2.75 (Blender(®) Foundation, Amsterdam, Nederland) software packages. The images registered with angular distortion presented a gradual decrease in height when compared to the reference. The digital technique for the correction of the PPP is a valuable tool for forensic applications using photographic imaging modalities, such as forensic facial analysis.

  12. A novel acoustic method for gas flow measurement using correlation techniques

    NASA Astrophysics Data System (ADS)

    Knuuttila, Matti Tapani

    The study demonstrates a new kind of acoustic method for gas flow measurement. The method uses upstream and downstream propagating low frequency plane wave and correlation techniques for volume flow rate determination. The theory of propagating low frequency plane waves in the pipe is introduced and is proved empirically to be applicable for flow measurement. The flow profile dependence of the method is verified and found to be negligible at least in the region of moderate perturbations. The physical principles of the method were applied in practice in the form of a flowmeter with new design concepts. The developed prototype meters were verified against the reference standard of NMI (Nederlands Meetinstituut), which showed that a wide dynamic range of 1:80 is achievable with total expanded uncertainty below 0.3%. Also the requirements used for turbine meters of linearity, weighted mean error and stability were shown to be well fulfilled. A brief comparison with other flowmeter types shows the new flowmeter to be competitive. The advantages it offers are a small pressure drop over the meter, no blockage of flow in possible malfunction, no pulsation to flow, essentially no moving parts, and the possibility for bidirectional measurements. The introduced flowmeter is also capable of using the introduced flowmeter is also capable of using the telephone network or a radio-modem to read the consumption of gas and report its operation to the user.

    The Precise Timing Facility (PTF) is an element of the Galileo Ground Mission Segment (GMS) and is responsible for maintaining and distributing the Galileo System Time (GST). The PTF is based on a set of Caesium clocks and Active Hydrogen Maser clocks, the combination of which should be able to provide the required precision and stability of the GST. As the PTF is a critical element within the GMS, diversity is applied in that two PTFs are made by two different companies. The subject of this paper is the PTF that is being developed by Kayser-Threde. To perform the Assembly, Integration and Verification (AIV) activities of the PTF, a dedicated test platform, PTF-AIVP, is developed by the National Aerospace Laboratory, NLR (the Netherlands) and the Nederlands Meetinstituut (NMi). The PTF-AIVP will be used to measure and analyse the (physical) output of the PTF, so that the stringent precision and stability requirements can be verified. Furthermore, it will simulate other Elements in the GMS that are connected to the PTF.

    At the Nederlands Centrum voor Laser Research (NCLR) a 1 kHz diode-pumped Nd:YAG Master Oscillator Power Amplifier (MOPA) chain with a Stimulated Brillouin Scattering (SBS) Phase Conjugate mirror is designed and operated. A small Brewster angle Nd:YAG slab (2 by 2 by 20 mm) is side pumped with 200 μs diode pulses in a stable oscillator. The oscillator is Q-switched and injection seeded with a commercial diode pumped single frequency CW Nd:YAG laser. The output consists of single-transverse, single-longitudinal mode 25 ns FWHM-pulses at 1064 nm. The oscillator slab is imaged on a square aperture that transmits between 3 and 2 mJ (at 100 and 400 Hz, resp.) The aperture is subsequently imaged four times in the amplifier. The amplifier is a 3 by 6 by 60 mm Brewster angle zig-zag slab, pumped by an 80-bar diode stack with pulses up to 250 μs. After the second pass the light is focused in two consecutive cells containing Freon-113 for wave-front reversal in an oscillator/amplifier-setup with a reflectivity of 60%. The light then passes through the amplifier twice more to produce 20 W (at 400 Hz) of output with near diffraction limited beam quality. To increase the output to 50 W at 1 kHz thermal lensing in the oscillator will be reduced.

    Recently, cereblon (CRBN) expression was found to be essential for the activity of thalidomide and lenalidomide. In the present study, we investigated whether the clinical efficacy of thalidomide in multiple myeloma is associated with CRBN expression in myeloma cells. Patients with newly diagnosed multiple myeloma were included in the HOVON-65/GMMG-HD4 trial, in which postintensification treatment in 1 arm consisted of daily thalidomide (50 mg) for 2 years. Gene-expression profiling, determined at the start of the trial, was available for 96 patients who started thalidomide maintenance. In this patient set, increase of CRBN gene expression was significantly associated with longerprogression-free survival (P = .005). In contrast, no association between CRBN expression and survival was observed in the arm with bortezomib maintenance. We conclude that CRBN expression may be associated with the clinical efficacy of thalidomide. This trial has been registered at the Nederlands Trial Register (www.trialregister.nl) as NTR213; at the European Union Drug Regulating Authorities Clinical Trials (EudraCT) as 2004-000944-26; and at the International Standard Randomized Controlled Trial Number (ISRCTN) as 64455289.

    There is increasing discussion in the Netherlands about the introduction of a threshold value for the costs per extra year of life when reimbursing costs of new drugs. The Medicines Committee ('Commissie Geneesmiddelen'), a division of the Netherlands National Healthcare Institute ('Zorginstituut Nederland'), advises on reimbursement of costs of new drugs. This advice is based upon the determination of therapeutic value of the drug and the results of economic evaluations. Mathematical models that predict future costs and effectiveness are often used in economic evaluations; these models can vary greatly in transparency and quality due to author assumptions. Standardisation of cost-effectiveness models is one solution to overcome the unwanted variation in quality. Discussions about the introduction of a threshold value can only be meaningful if all involved are adequately informed, and by high quality in cost-effectiveness research and, particularly, economic evaluations. Collaboration and discussion between medical specialists, patients or patient organisations, health economists and policy makers, both in development of methods and in standardisation, are essential to improve the quality of decision making.

    George Lievin Henri Ellerman (1817-1849) followed his medical-military training at the Military Medical Training College (RKMG) in Utrecht, the Netherlands, from 1835 to 1839, and gained his PhD from Leiden University in 1841. From 1843 to 1849 he was a lecturer in pharmacology at the RKMG. He was one of the first editors of the Nederlandsch Lancet. Together with his fellow board members Donders and Jansen he set this journal on a new course. Due to the new mix of scientific and practice-oriented articles the journal developed into the most important medical scientific journal in the Netherlands; it was however not among the journals that merged to become the Nederlands Tijdschrift voor Geneeskunde [Dutch Journal of Medicine]. In 1846 Ellerman published a Dutch translation of Friedrich Oesterlen's textbook of pharmacology 'Handbuch der Heilmittellehre'. This book was considered to be a complete and lucid survey of pharmacology and a major step towards a more scientific pharmacology. After his death at the age of 32, he was remembered as a good scientist and dedicated, hardworking lecturer.

    Adrianus Dingeman de Groot (1914-2006) was one of the most influential Dutch psychologists. He became famous for his work "Thought and Choice in Chess", but his main contribution was methodological--De Groot co-founded the Department of Psychological Methods at the University of Amsterdam (together with R. F. van Naerssen), founded one of the leading testing and assessment companies (CITO), and wrote the monograph "Methodology" that centers on the empirical-scientific cycle: observation-induction-deduction-testing-evaluation. Here we translate one of De Groot's early articles, published in 1956 in the Dutch journal Nederlands Tijdschrift voor de Psychologie en Haar Grensgebieden. This article is more topical now than it was almost 60years ago. De Groot stresses the difference between exploratory and confirmatory ("hypothesis testing") research and argues that statistical inference is only sensible for the latter: "One 'is allowed' to apply statistical tests in exploratory research, just as long as one realizes that they do not have evidential impact". De Groot may have also been one of the first psychologists to argue explicitly for preregistration of experiments and the associated plan of statistical analysis. The appendix provides annotations that connect De Groot's arguments to the current-day debate on transparency and reproducibility in psychological science.

    Research into placebo effects has convincingly shown that inducing positive outcome expectations can reduce pain and other physical sensations. However, the comparative effects of different expectation inductions, such as verbal suggestion or mental imagery, and their generic effects on physical sensitivity, to different sensations such as pain, itch, and fatigue, are still largely unknown. In the current study, we assessed the individual and combined effects of verbal suggestion and imagery on pain, itch, and fatigue as indicators of physical sensitivity in a randomized study design. Healthy participants (n = 116) were given an inert (placebo) capsule that was said to be effective for reducing physical sensitivity in either the majority (positive verbal suggestion) or the minority (control verbal suggestion) of users. Subsequently, they imagined either their best possible health (positive imagery) or a typical day (control imagery). Sensitivity to pain, itch, and fatigue was tested using a cold pressor test, histamine iontophoresis, and a bicycle test, respectively. Heart rate and skin conductance were recorded continuously. Results showed that positive verbal suggestion and imagery successfully induced positive expectations, but they did not affect physical sensitivity, as indicated by sensitivity to pain, itch, or fatigue, or concurrent physiological responses. These results could indicate that the specificity and concreteness of expectation inductions might be important for their applicability in the treatment of physical symptoms.

    Nutritional supplements can be a source of positive doping cases as some supplements contain prohibited substances without showing this on their label. This problem has existed for some time and has been extensively studied in the past 8 years. The sport of tennis has played a particular role in this problem because of some peculiar doping cases within its community. This article focuses on this particular doping problem, explaining the background and reviewing the available literature. It presents the first 3 years of experience within the Netherlands Security System Nutritional Supplements Elite Sports (“Nederlands Zekerheidssysteem Voedingssupplementen Topsport” or NZVT) and explains the most extensive system established to combat this particular doping problem. The NZVT experience has shown that paper‐based quality systems are still prone to possible contaminations, which leads to the conclusion that the best possible solution for athletes who wish to use nutritional supplements must include laboratory‐based analysis for doping substances, preferably repeated for every new batch. The most important educational message, however, is to use a nutritional supplement only if it is deemed of benefit by a nutritional expert. PMID:17957017

    2010-01-01

    Small satellites and in particular CubeSats, have increasingly become more viable as platforms for payloads typically requiring much larger bus structures. As advances in technology make payloads and instruments for space missions smaller, lighter and more power efficient, a niche market is emerging from the university community to perform rapidly developed, low-cost missions on very small spacecraft - micro, nano, and picosatellites. In just the last few years, imaging, biological and new technology demonstration missions have been either proposed or have flown using variations of the CubeSat structure as a basis. As these missions have become more complex, and the CubeSat standard has increased in both size (number of cubes) and mass, available power has become an issue. Body-mounted solar cells provide a minimal amount of power; deployable arrays improve on that baseline but are still limited. To truly achieve maximum power, deployed tracked arrays are necessary. To this end, Honeybee Robotics Spacecraft Mechanisms Corporation, along with MMA of Nederland Colorado, has developed a solar array drive assembly (SADA) and deployable solar arrays specifically for CubeSat missions. In this paper, we discuss the development of the SADA.

    This article gives a brief sketch of quality management in Dutch health care. Our focus is upon the governance of guideline development and quality measurement. Governance is conceptualized as the structure and process of steering of quality management. The governance structure of guideline development in the Netherlands can be conceptualized as a network without central coordination. Much depends upon the self-initiative of stakeholders. A similar picture can be found in quality measurement. Special attention is given to the development of care standards for chronic disease. Care standards have a broader scope than guidelines and take an explicit patient perspective. They not only contain evidence-based and up-to-date guidelines for the care pathway but also contain standards for self-management. Furthermore, they comprise a set of indicators for measuring the quality of care of the entire pathway covered by the standard. The final part of the article discusses the mission, tasks and strategic challenges of the newly established National Health Care Institute (Zorginstituut Nederland), which is scheduled to be operative in 2013.

    2014-01-01

    Background In recent years, preventive and clinical interventions for cardiovascular risk management have been implemented widely in primary care in the Netherlands. Although this has enhanced quality and outcomes of cardiovascular risk management, further improvement remains possible. In the planned observational study, we aim to examine the role of social networks of healthcare providers and patients in quality and outcomes of cardiovascular risk management. Methods/Design In a longitudinal observational study, data on social networks of approximately 300 primary care providers from 30 general practices and 900 cardiovascular patients will be collected twice, with a six month interval, using a mix of measures. Social networks are documented with specifically designed questionnaires for patients, relatives, and healthcare professionals. For each included patient, we will extract from medical records to gather data on clinical processes and cardiovascular risk predictors. Data on self-management and psychosocial outcomes of patients will be collected using questionnaires for patients. The analysis focuses on identifying network characteristics, which are associated with (changes in) cardiovascular risk management or self-management. Discussion This research will provide insight into the role of social networks of patients and providers in cardiovascular risk management in primary practice.

    AHN-2 is the second part of the Actueel Hoogtebestand Nederland project, which concerns the acquisition of high-resolution altimetry data over the entire Netherlands using airborne laser scanning. The accuracy assessment of laser altimetry data usually relies on comparing corresponding tie elements, often points or lines, in the overlapping strips. This paper proposes a new approach to strip adjustment and accuracy assessment of AHN-2 data by using planar features. In the proposed approach a transformation is estimated between two overlapping strips by minimizing the distances between points in one strip and their corresponding planes in the other. The planes and the corresponding points are extracted in an automated segmentation process. The point-to-plane distances are used as observables in an estimation model, whereby the parameters of a transformation between the two strips and their associated quality measures are estimated. We demonstrate the performance of the method for the accuracy assessment of the AHN-2 dataset over Zeeland province of The Netherlands. The results show vertical offsets of up to 4 cm between the overlapping strips, and horizontal offsets ranging from 2 cm to 34 cm.

    Background Animal studies have shown that methylphenidate (MPH) and fluoxetine (FLX) have different effects on dopaminergic and serotonergic system in the developing brain compared to the developed brain. The effects of Psychotropic drugs On the Developing brain (ePOD) study is a combination of different approaches to determine whether there are related findings in humans. Methods/Design Animal studies were carried out to investigate age-related effects of psychotropic drugs and to validate new neuroimaging techniques. In addition, we set up two double-blind placebo controlled clinical trials with MPH in 50 boys (10–12 years) and 50 young men (23–40 years) suffering from ADHD (ePOD-MPH) and with FLX in 40 girls (12–14 years) and 40 young women (23–40 years) suffering from depression and anxiety disorders (ePOD-SSRI). Trial registration numbers are: Nederlands Trial Register NTR3103 and NTR2111. A cross-sectional cohort study on age-related effects of these psychotropic medications in patients who have been treated previously with MPH or FLX (ePOD-Pharmo) is also ongoing. The effects of psychotropic drugs on the developing brain are studied using neuroimaging techniques together with neuropsychological and psychiatric assessments of cognition, behavior and emotion. All assessments take place before, during (only in case of MPH) and after chronic treatment. Discussion The combined results of these approaches will provide new insight into the modulating effect of MPH and FLX on brain development. PMID:24552282

    Background Fms-like tyrosine kinase-3 (FLT3) gene mutations are frequent in acute promyelocytic leukemia but their prognostic value is not well established. Design and Methods We evaluated FLT3-internal tandem duplication and FLT3-D835 mutations in patients treated with all-trans retinoic acid and anthracycline-based chemotherapy enrolled in two subsequent trials of the Programa de Estudio y Tratamiento de las Hemopatías Malignas (PETHEMA) and Hemato-Oncologie voor Volwassenen Nederland (HOVON) groups between 1996 and 2005. Results FLT3-internal tandem duplication and FLT3-D835 mutation status was available for 306 (41%) and 213 (29%) patients, respectively. Sixty-eight (22%) and 20 (9%) patients had internal tandem duplication and D835 mutations, respectively. Internal tandem duplication was correlated with higher white blood cell and blast counts, lactate dehydrogenase, relapse-risk score, fever, hemorrhage, coagulopathy, BCR3 isoform, M3 variant subtype, and expression of CD2, CD34, human leukocyte antigen-DR, and CD11b surface antigens. The FLT3-D835 mutation was not significantly associated with any clinical or biological characteristic. Univariate analysis showed higher relapse and lower survival rates in patients with a FLT3-internal tandem duplication, while no impact was observed in relation to FLT3-D835. The prognostic value of the FLT3-internal tandem duplication was not retained in the multivariate analysis. Conclusions FLT3-internal tandem duplication mutations are associated with several hematologic features in acute promyelocytic leukemia, in particular with high white blood cell counts, but we were unable to demonstrate an independent prognostic value in patients with acute promyelocytic leukemia treated with all-trans retinoic acid and anthracycline-based regimens.

    Objective This study explored qualitative treatment-subgroup interactions within data of a RCT with two cognitive behavioral treatments (CBT) for adolescents with ADHD: a planning-focused (PML) and a solution-focused CBT (SFT). Qualitative interactions imply that which treatment is best differs across subgroups of patients, and are therefore most relevant for personalized medicine. Methods Adolescents with ADHD (N = 159) received either PML or SFT. Pre-, post- and three-month follow-up data were gathered on parent-rated ADHD symptoms and planning problems. Pretreatment characteristics were explored as potential qualitative moderators of pretest to follow-up treatment effects, using an innovative analyses technique (QUINT; Dusseldorp & Van Mechelen, 2014). In addition, qualitative treatment-subgroup interactions for the therapeutic changes from pre- to posttest and from post- to follow-up test were investigated. Results For the entire time span from pretest to follow-up only a quantitative interaction was found, while from posttest to follow-up qualitative interactions were found: Adolescents with less depressive symptoms but more anxiety symptoms showed more improvement when receiving PML than SFT, while for other adolescents the effects of PML and SFT were comparable. Discussion Whereas subgroups in both treatments followed different trajectories, no subgroup was found for which SFT outperformed PML in terms of the global change in symptoms from pretest to three months after treatment. This implies that, based on this exploratory study, there is no need for personalized treatment allocation with regard to the CBTs under study for adolescents with ADHD. However, for a subgroup with comorbid anxiety symptoms but low depression PML clearly appears the treatment of preference. Trial Registration Nederlands Trial Register NTR2142 PMID:26977602

    Ground-based observations with a Fourier transform spectrometer in the infrared region (FTIR) were performed in Kiev (Ukraine) during the time frames August-October 2005 and June-October 2006 within the Ozone Monitoring Instrument (OMI) validation project 2907 entitled "OMI validation by ground based remote sensing: ozone columns and profiles" in the frame of the international European Space Agency/Netherlands Agency for Aerospace Programmes/Royal Dutch Meteorological Institute OMI Announcement of Opportunity effort. Ozone column data for 2005 were obtained by modeling the ozone spectral band at 9.6 μm with the radiative transfer code MODTRAN3.5. Our total ozone column values were found to be lower than OMI Differential Optical Absorption Spectroscopy (DOAS) total ozone column data by 8-10 Dobson units (DU, 1 DU = 0.001 atm cm) on average, while our observations have a relatively small standard error of about 2 DU. Improved modeling of the ozone spectral band, now based on HITRAN-2004 spectral data as calculated by us, moves our results toward better agreement with the OMI DOAS total ozone column data. The observations made during 2006 with a modernized FTIR spectrometer and higher signal-to-noise ratio were simulated by the MODTRAN4 model computations. For ozone column estimates the Aqua Atmospheric Infrared Sounder satellite water vapor and temperature profiles were combined with the Aura Microwave Limb Sounder stratospheric ozone profiles and Tropospheric Emission Monitoring Internet Service-Koninklijk Nederlands Meteorologisch Instituut climatological profiles to create a priori input files for spectral modeling. The MODTRAN4 estimates of ozone columns from the 2006 observations compare rather well with the OMI total ozone column data: standard errors are of 1.11 DU and 0.68 DU, standard deviation are of 8.77 DU and 5.37 DU for OMI DOAS and OMI Total Ozone Mapping Spectrometer, respectively.

    We investigate the effects of retrieval radiation schemes and parameters on trend analysis using tropospheric nitrogen dioxide (NO2) vertical column density (VCD) measurements over the United States. Ozone Monitoring Instrument (OMI) observations from 2005 through 2012 are used in this analysis. We investigated two radiation schemes, provided by National Aeronautics and Space Administration (NASA TOMRAD) and Koninklijk Nederlands Meteorologisch Instituut (KNMI DAK). In addition, we analyzed trend dependence on radiation parameters, including surface albedo and viewing geometry. The cross-track mean VCD average difference is 10-15% between the two radiation schemes in 2005. As the OMI anomaly developed and progressively worsens, the difference between the two schemes becomes larger. Furthermore, applying surface albedo measurements from the Moderate Resolution Imaging Spectroradiometer (MODIS) leads to increases of estimated NO2 VCD trends over high-emission regions. We find that the uncertainties of OMI-derived NO2 VCD trends can be reduced by up to a factor of 3 by selecting OMI cross-track rows on the basis of their performance over the ocean [see abstract figure]. Comparison of OMI tropospheric VCD trends to those estimated based on the EPA surface NO2 observations indicate using MODIS surface albedo data and a more narrow selection of OMI cross-track rows greatly improves the agreement of estimated trends between satellite and surface data. This figure shows the reduction of uncertainty in OMI NO2 trend by selecting OMI cross-track rows based on the performance over the ocean. With this technique, uncertainties within the seasonal trend may be reduced by a factor of 3 or more (blue) compared with only removing the anomalous rows: considering OMI cross-track rows 4-24 (red).

The OSI SAF consortium is constituted of Météo-France as leading entity, and Met.no (Norske ee Meteorologiske Institutt), DMI (Danish Meteorological Institute), SMHI (Swedish Meteorolog-ical and Hydrological Institute), KNMI (Koninklijk Nederlands Meteorologisch Instituut) and IFREMER (Institut Français de Recherche pour l'Exploitation de la MER) as co-operating c entities. The two previous phases of the EUMETSAT Ocean and Sea Ice Satellite Application Facility (OSI SAF), the Development phase (1997-2002) and the IOP (initial Operations Phase, 2002-2007) met the main target which was to develop, validate and then produce operationally quality controlled satellite-derived products related to four key parameters of the sea surface (Sea Surface Temperature, Radiative Fluxes, Sea Ice, Wind) over various geographical coverage from regional to global. These products are currently available in near real time both through EUMETCAST and local FTP servers, and off line from local archive. Archiving at EUMETSAT Data Center is also being implemented. The current phase of the EUMETSAT OSI SAF, the CDOP (Continuous Development and Operations Phase, 2007-2012) has taken into account new requirements expressed in particular in the context of GODAE, GHRSST and GCOS at international level, and GMES (through MyOcean) at European level, with in particular a strong need for increasing the temporal and geographical resolution of the products and user friendly interfaces allowing access to high level allowing flexible extraction An overview on the OSI SAF project and its current and future production in the time frame of the CDOP will be presented, as well as first glance on the following phase, the CDOP-2, that will cover 2012 to 2017.

    Background The aim of this study was to evaluate the long term effects after discharge of a hospital-based geriatric liaison intervention to prevent postoperative delirium in frail elderly cancer patients treated with an elective surgical procedure for a solid tumour. In addition, the effect of a postoperative delirium on long term outcomes was examined. Methods A three month follow-up was performed in participants of the Liaison Intervention in Frail Elderly study, a multicentre, prospective, randomized, controlled trial. Patients were randomized to standard treatment or a geriatric liaison intervention. The intervention consisted of a preoperative geriatric consultation, an individual treatment plan targeted at risk factors for delirium and daily visits by a geriatric nurse during the hospital stay. The long term outcomes included: mortality, rehospitalisation, Activities of Daily Living (ADL) functioning, return to the independent pre-operative living situation, use of supportive care, cognitive functioning and health related quality of life. Results Data of 260 patients (intervention n = 127, Control n = 133) were analysed. There were no differences between the intervention group and usual-care group for any of the outcomes three months after discharge. The presence of postoperative delirium was associated with: an increased risk of decline in ADL functioning (OR: 2.65, 95% CI: 1.02–6.88), an increased use of supportive assistance (OR: 2.45, 95% CI: 1.02–5.87) and a decreased chance to return to the independent preoperative living situation (OR: 0.18, 95% CI: 0.07–0.49). Conclusions A hospital-based geriatric liaison intervention for the prevention of postoperative delirium in frail elderly cancer patients undergoing elective surgery for a solid tumour did not improve outcomes 3 months after discharge from hospital. The negative effect of a postoperative delirium on late outcome was confirmed. Trial Registration Nederlands Trial Register, Trial ID NTR 823

    Introduction Physical fitness is an important prognostic factor in heart failure (HF). To improve fitness, different types of exercise have been explored, with recent focus on high-intensity interval training (HIT). We comprehensively compared effects of HIT versus continuous training (CT) in HF patients NYHA II-III on physical fitness, cardiovascular function and structure, and quality of life, and hypothesize that HIT leads to superior improvements compared to CT. Methods Twenty HF patients (male:female 19:1, 64±8 yrs, ejection fraction 38±6%) were allocated to 12-weeks of HIT (10*1-minute at 90% maximal workload—alternated by 2.5 minutes at 30% maximal workload) or CT (30 minutes at 60–75% of maximal workload). Before and after intervention, we examined physical fitness (incremental cycling test), cardiac function and structure (echocardiography), vascular function and structure (ultrasound) and quality of life (SF-36, Minnesota living with HF questionnaire (MLHFQ)). Results Training improved maximal workload, peak oxygen uptake (VO2peak) related to the predicted VO2peak, oxygen uptake at the anaerobic threshold, and maximal oxygen pulse (all P<0.05), whilst no differences were present between HIT and CT (N.S.). We found no major changes in resting cardiovascular function and structure. SF-36 physical function score improved after training (P<0.05), whilst SF-36 total score and MLHFQ did not change after training (N.S.). Conclusion Training induced significant improvements in parameters of physical fitness, although no evidence for superiority of HIT over CT was demonstrated. No major effect of training was found on cardiovascular structure and function or quality of life in HF patients NYHA II-III. Trial Registration Nederlands Trial Register NTR3671 PMID:26517867

    Historical films made by neuroscientists have shown up in several countries during past years. Although originally supposed to have been lost, we recently found a collection of films produced between 1909 and 1940 by Rudolf Magnus (1873-1927), professor of pharmacology (Utrecht) and his student Gysbertus Rademaker (1887-1957), professor of physiology (1928, succeeding Willem Einthoven) and neurology (1945, both in Leiden). Both collections deal with the physiology of body posture by the equilibrium of reflex musculature contractions for which experimental studies were done with animals (labyrinthectomies, cerebellectomies, and brainstem sections) and observations on patients. The films demonstrate the results of these studies. Moreover, there are films with babies showing tonic neck reflexes and moving images capturing adults with cerebellar symptoms following cerebellectomies for tumors and several other conditions. Magnus' studies resulted in his well-known Körperstellung (1924, "Body Posture") and Rademaker's research in his Das Stehen (1931, "Standing"). The films probably had an educative and scientific purpose. Magnus demonstrated his films at congresses, including the Eighth International Congress of Physiologists (Vienna, 1910) and Rademaker screened his moving images at meetings of the Amsterdam Neurologists Society (at several occasions as reflected in the Winkler-Monakow correspondence and the Nederlands Tijdschrift voor Geneeskunde). Next to these purposes, the films were used to analyze movement and a series of images from the films were published in articles and books. The films are important historical sources that provide a portrait of the pre-World War II era in neuroscience, partly answering questions on how physicians dealt with patients and researchers with their laboratory animals. Moreover, the films confirm that cinematography was an important scientific tool in neuroscience research.

  15. Splint: the efficacy of orthotic management in rest to prevent equinus in children with cerebral palsy, a randomised controlled trial

    PubMed Central

    2012-01-01

    Background Range of motion deficits of the lower extremity occur in about the half of the children with spastic cerebral palsy (CP). Over time, these impairments can cause joint deformities and deviations in the children's gait pattern, leading to limitations in moblity. Preventing a loss of range of motion is important in order to reduce secondary activity limitations and joint deformities. Sustained muscle stretch, imposed by orthotic management in rest, might be an effective method of preventing a decrease in range of motion. However, no controlled study has been performed. Methods A single blind randomised controlled trial will be performed in 66 children with spastic CP, divided over three groups with each 22 participants. Two groups will be treated for 1 year with orthoses to prevent a decrease in range of motion in the ankle (either with static or dynamic knee-ankle-foot-orthoses) and a third group will be included as a control group and will receive usual care (physical therapy, manual stretching). Measurements will be performed at baseline and at 3, 6, 9 and 12 months after treatment allocation. The primary outcome measure will be ankle dorsiflexion at full knee extension, measured with a custom designed hand held dynamometer. Secondary outcome measures will be i) ankle and knee flexion during gait and ii) gross motor function. Furthermore, to gain more insight in the working mechanism of the orthotic management in rest, morphological parameters like achilles tendon length, muscle belly length, muscle fascicle length, muscle physiological cross sectional area length and fascicle pennation angle will be measured in a subgroup of 18 participants using a 3D imaging technique. Discussion This randomised controlled trial will provide more insight into the efficacy of orthotic management in rest and the working mechanisms behind this treatment. The results of this study could lead to improved treatments. Trial Registration Number Nederlands Trial Register NTR

    The replacement of medical-grade silicone with industrial-grade silicone material in some silicone gel-filled breast implants (SBI) manufactured by Poly Implant Prothèse and Rofil Medical Nederland B.V., reported in 2010, which resulted in a higher rupture tendency of these SBI, demonstrates the need for non-invasive, sensitive monitoring and screening methods. Therefore a sensitive method based on large volume injection-gas chromatography coupled to mass spectrometry (LVI-GC/MS) was developed to determine octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), and dodecamethylcyclo-hexasiloxane (D6) in blood samples from women with intact (n = 13) and ruptured SBI (n = 11). With dichloromethane extraction, sample cooling during preparation, and analysis extraction efficiencies up to 100 % and limits of detection of 0.03-0.05 ng D4-D6/g blood were achieved. Blood samples from women with SBI were investigated. In contrast to women with intact SBI, in blood from women with ruptured SBI higher D4 and D6 concentrations up to 0.57 ng D4/g blood and 0.16 ng D6/g blood were detected. With concentrations above 0.18 D4 ng/blood and 0.10 ng D6/g blood as significant criteria for ruptured SBI, this developed analytical preoperative diagnostic method shows a significant increase of the recognition rate. Finally a higher precision (error rate 17%) than the commonly used clinical diagnostic method, mamma sonography (error rate 46%), was achieved.

    2013-01-01

    Background Self-management is recognized as the cornerstone of overall diabetes management. Web-based self-management programs have the potential of supporting type 2 diabetes patients with managing their diabetes and reducing the workload for the care provider, where the addition of online coaching could improve patient motivation and reduce program attrition. This study aims to test the hypothesis that a web-based self-management program with coaching will prove more effective on improving patient self-management behavior and clinical outcome measures than a web-based self-management program without coaching. Methods The effects of a web-based self-management program with and without coaching will be tested with a nested randomized controlled trial within a healthcare group in the Netherlands. In one year 220 type 2 diabetes patients will be randomized into an intervention group (n = 110) or a control group (n = 110). The control group will receive only the online self-management program. The intervention group will receive the online self-management program and additional online coaching. Participants will be followed for one year, with follow-up measurements at 6 and 12 months. Discussion The intervention being tested is set to support type 2 diabetes patients with their diabetes self-management and is expected to have beneficial effects on self-care activities, well being and clinical outcomes. When proven effective this self-management support program could be offered to other health care groups and their type 2 diabetes patients in the Netherlands.

    Purpose To construct and validate among patients with multiple myeloma (MM) who were treated with intensive therapy a prognostic index of early MM progression–related death. Patients and Methods Patient-level data from the Intergroupe Francophone du Myélome (IFM) 2005-01 trial (N = 482) were used to construct the prognostic index. The event was MM progression–related death within 2 years from treatment initiation. The index was validated using data from three other trials: the Gruppo Italiano Malattie Ematologiche dell' Adulto (GIMEMA) 26866138-MMY-3006 trial (N = 480), the Programa para el Estudio de la Terapéutica en Hemopatía Maligna (PETHEMA)–GEMMENOS65 trial (N = 390), and the Hemato-Oncologie voor Volwassenen Nederland (HOVON) –65/German-Speaking Myeloma Multicenter Group (GMMG) –HD4 trial (N = 827). Results The risk of early MM progression–related death was related to three independent prognostic variables: lactate dehydrogenase (LDH) higher than than normal, International Staging System 3 (ISS3), and adverse cytogenetics [t(4;14) and/or del(17p)]. These three variables enabled the definition of an ordinal prognostic classification composed of four scores (0 to 3). Patients with a score of 3, defined by the presence of t(4;14) and/or del(17p) in addition to ISS3 and/or high LDH, comprised 5% (20 of 387 patients) to 8% (94 of 1,139 patients) of the patients in the learning and validation samples, respectively, and they had a very poor prognosis. When applied to the population of 855 patients who had received bortezomib-based induction therapy in the four trials, the prognostic classification was also able to segregate patients into four categories, with a very poor prognosis attributed to patients with a score of 3. Conclusion Our model allows the simple definition of a subgroup of MM patients at high risk of early MM progression–related death despite the use of the most modern and effective strategies.

    In the Physikalisch-Technische Bundesanstalt (PTB) the primary standard for on-line flowrate measurements using the laser Doppler anemometer (LDA) technique has been extended to a three-component LDA to improve velocity profile measurements in the boundary layers of a nozzle flow. The LDA flowrate measuring facility now consists of a two-colour argon ion LDA and a wavelength-stabilized GaAlAs diode laser LDA. The gas flowrate is obtained by numerical integration of the measured velocity profiles across the exit plane of the nozzle. High local resolution of the velocity profile measurements is achieved by perpendicular orientation of the measurement volumes of the two-component gas laser LDA and the semiconductor diode laser LDA (LD-LDA). This allows the resolution in the boundary layer to be improved significantly to velocity gradients. The present work presents the LD-LDA system for precise velocity profile measurements at flow velocities of up to 120 m/s; selected profile measurements are described in detail to demonstrate the high resolution and the symmetry of the flow profile. For the first time a wavelength-stabilized miniaturized diode laser LDA has been successfully applied in precise velocity measurements, and comparisons with well-established gas laser LDAs have been made. The uncertainty of the flowrate measurement up to 5 500 m3/h is 0,1% for air at atmospheric pressure. A turbine gas meter, type Elster G2500, was calibrated with the LDA and used as a transfer standard for an intercomparison with the Nederlands Meetinstituut (NMI) in the flowrate range up to 5 500 m3/h with and without the installation of perforated plates to condition the flow in the inlet section of the gas meter. The results of the comparison experiment clearly show the reliability and accuracy of the online flowrate measurement of gases and underline the necessity for a detailed research programme to investigate the relationship between installation effects, upstream flow conditions

    Background In the Netherlands, hospitals with quality or safety issues are put under intensified supervision by the Dutch Health Care Inspectorate, which involves frequent announced and unannounced site visits and other measures. Patient rating sites are an upcoming phenomenon in health care. Patient reviews might be influenced by perceived quality including the media coverage of health care providers when the health care inspectorate imposes intensified supervision, but no data are available to show how these are related. Objective The aim of this study was to investigate whether and how being under intensified supervision of the health care inspectorate influences online patient ratings of hospitals. Methods We performed a longitudinal study using data from the patient rating site Zorgkaart Nederland, from January 1, 2010 to December 31, 2015. We compared data of 7 hospitals under intensified supervision with a control group of 28 hospitals. The dataset contained 43,856 ratings. We performed a multilevel logistic regression analysis to account for clustering of ratings within hospitals. Fixed effects in our analysis were hospital type, time, and the period of intensified supervision. Random effect was the hospital. The outcome variable was the dichotomized rating score. Results The period of intensified supervision was associated with a low rating score for the hospitals compared with control group hospitals; both 1 year before intensified supervision (odds ratio, OR, 1.67, 95% CI 1.06-2.63) and 1 year after (OR 1.79, 95% CI 1.14-2.81) the differences are significant. For all periods, the odds on a low rating score for hospitals under intensified supervision are higher than for the control group hospitals, corrected for time. Time is also associated with low rating scores, with decreasing ORs over time since 2010. Conclusions Hospitals that are confronted with intensified supervision by the health care inspectorate have lower ratings on patient rating sites. The

Conclusions Older, male, and employed participants, and those with a lower income, higher body mass index, and a relatively unhealthy lifestyle were more likely to initiate a CT module. Module completers predominantly had a higher income and age. The current program therefore succeeded in reaching those people who benefit most from online lifestyle interventions. However, these people tended to disengage from the program. This underlines the importance of additional research into program adjustments and strategies that can be used to stimulate prolonged program use. Furthermore, sending periodic email prompts significantly increased revisits to the program. Though promising, this effect was modest and needs to be further examined, in order to maximize the potential of periodic email prompting.

These 95% confidence intervals do not extend below the predefined threshold of 0.69 for inferiority. Multiple pregnancy rates per ongoing pregnancy were 6% (7/121) after in vitro fertilisation with single embryo transfer, 5% (5/102) after in vitro fertilisation in a modified natural cycle, and 7% (8/119) after intrauterine insemination with ovarian hyperstimulation (one sided P=0.52 for in vitro fertilisation with single embryo transfer compared with intrauterine insemination with ovarian hyperstimulation; one sided P=0.33 for in vitro fertilisation in a modified natural cycle compared with intrauterine insemination with controlled ovarian hyperstimulation). Conclusions In vitro fertilisation with single embryo transfer and in vitro fertilisation in a modified natural cycle were non-inferior to intrauterine insemination with controlled ovarian hyperstimulation in terms of the birth of a healthy child and showed comparable, low multiple pregnancy rates.

    hydro-meteorological network, consisting of about 30 rain gauges and 10 hydrometers, monitors this medium-size watershed. A decade of rainfall-runoff event observations are available. Severe rainfall events were identified with reference to a main raingauge station, by using an interevent time definition and a depth threshold. Rainfall depths were thus derived and the spatial variability of their association degree was represented by using the Kendall coefficient. A unique copula model based on Gumbel copula function was finally found to be suitable to represent the dependence structure relating to rainfall depths observed in distinct raingauges.

A total of 1994 participants underwent CT scanning: 42 participants (2.1%) were diagnosed with lung cancer; 36 out of 42 (85.7%) of the screen-detected cancers were identified as stage 1 or 2, and 35 (83.3%) underwent surgical resection as their primary treatment. Lung cancer was more common in the lowest socioeconomic group. Short-term adverse psychosocial consequences were observed in participants who were randomised to the intervention arm and in those who had a major lung abnormality detected, but these differences were modest and temporary. Rollout of screening as a service or design of a full trial would need to address issues of outreach. The health-economic analysis suggests that the intervention could be cost-effective but this needs to be confirmed using data on actual lung cancer mortality. CONCLUSIONS The UK Lung Cancer Screening (UKLS) pilot was successfully undertaken with 4055 randomised individuals. The data from the UKLS provide evidence that adds to existing data to suggest that lung cancer screening in the UK could potentially be implemented in the 60-75 years age group, selected via the Liverpool Lung Project risk model version 2 and using CT volumetry-based management protocols. FUTURE WORK The UKLS data will be pooled with the NELSON (Nederlands Leuvens Longkanker Screenings Onderzoek: Dutch-Belgian Randomised Lung Cancer Screening Trial) and other European Union trials in 2017 which will provide European mortality and cost-effectiveness data. For now, there is a clear need for mortality results from other trials and further research to identify optimal methods of implementation and delivery. Strategies for increasing uptake and providing support for underserved groups will be key to implementation. TRIAL REGISTRATION Current Controlled Trials ISRCTN78513845.

Conclusions Our findings indicate the general effectiveness and practicality of Web-based computer-tailored interventions in terms of increasing self-reported habit strength for physical activity and fruit and vegetable consumption. Self-efficacy and planning may play major roles in the mechanisms that facilitate the habit strength of these behaviors; therefore, they should be actively promoted in Web-based interventions.

    The most relevant results of a written questionnaire among veterinarians in the Netherlands are presented and discussed. The inquiry was performed by MarketResponse Nederland BV. The objective was to get an overview of the current perception and the future view of the profession. The response was 37%. Most respondents (66%) were practitioners, 7% were active in research or teaching institutions, 5% were governmental employees, 5% were employed in industry, and 17% did not belong to any of these categories (retired, unemployed etc.). Forty-seven per cent of the veterinarians practised mainly small animal medicine, 24% large animal medicine (cattle 15%, swine 8%, and poultry 1%), and 4% equine medicine; 24% worked in mixed practices. This division reflects the real-life situation. The percentage of female respondents was considerably higher in the group of recent graduates than in the other groups of graduates (increasing from 27% in the graduation period 1980-1989 to 56% in the period 1990-1999). Sixty per cent of the veterinarians worked more than 40 hours a week. Veterinarians considered themselves reliable, honest, professional, client-minded, and animal-friendly. According to them, the public perceived veterinarians as being animal-friendly, professional, and reliable. Veterinarians were less satisfied in their current position than other professional groups, particularly with regard to their income. Their current market position was considered indifferent or good. This position was influenced negatively by the decrease in the number of animals and competition from non-veterinarians and others. The situation could be improved by collaboration and practice fusions, specialization, and differentiation. More demanding and price-conscious clients and governmental regulations were considered important trends. Social, management, and marketing skills, increased knowledge and cooperation, and a vision of future developments were considered essential in order to be able

In the subgroup of adolescents who were at risk of mental health problems at baseline (and referred for a consultation with the nurse), the E-health4Uth and consultation group showed minor to moderate positive results in mental health status (SDQ: B=−1.79, 95% CI −3.35 to −0.22; YSR: B=−9.11, 95% CI −17.52 to −0.71) and health-related quality of life (B=7.81, 95% CI 2.41-13.21) at follow-up compared to adolescents in the control group who were at risk of mental health problems at baseline. Conclusions Findings from this study support the use of the E-health4Uth and consultation intervention in promoting the well-being of adolescents at risk of mental health problems. Future research is needed to further evaluate the effects of the consultation as a standalone intervention, and the dual approach of further tailored eHealth messages and a consultation.

    intervention was more costly and more effective in comparison with CAU. ICERs differed for both perspectives, namely €40 and €79 from the health care perspective to €62 and €144 for the societal perspective per incremental reduction of one glass of alcohol per week and one binge drinking occasion per 30 days, respectively. Subgroup analyses showed, from both perspectives and for both outcome measures, that the intervention was cost-effective for older adolescents (aged 17-19 years) and those at a lower educational level and, from a health care perspective, the male and nonreligious adolescent subgroups. Conclusions Computer-tailored feedback could be a cost-effective way to target alcohol use and binge drinking among adolescents. Including ICBs in the economic evaluation had an impact on the cost-effectiveness results of the analysis. It could be worthwhile to aim the intervention specifically at specific subgroups.

    Introducción: El cáncer de pulmón es la tercera neoplasia tumoral más frecuente en España, con unos 27.000 nuevos casos/ año, de los que el 80-85% son de etiología no microcítica (NSCLC) y en la mayoría de los casos diagnosticados en estadíos avanzados de la enfermedad, razón por la que es uno de los procesos oncológicos con mayores tasas de mortalidad (supervivencia media a los 5 años del 21,4%). Los principales esquemas de primera línea utilizados en el tratamiento del NSCLC son: cisplatino/pemetrexed (cis/pem), cisplatino/gemcitabina/ bevacizumab (cis/gem/bev), y carboplatino/paclitaxel/bevacizumab (carbo/pac/Bev). El objetivo del presente trabajo consistirá en realizar un análisis para estimar el ratio coste-eficacia de los esquemas antineoplásicos de primera línea en el tratamiento del NSCLC, desde la perspectiva de la gerencia hospitalaria. Metodos: Se elaboró un modelo matemático de coste-eficacia basado en un árbol de decisiones. Como variable de eficacia se utilizó la supervivencia libre de progresión, obtenida de los ensayos clínicos fase III PARAMOUNT, AVAIL y SAIL. El estudio se efectuó desde la perspectiva de la gerencia hospitalaria considerando únicamente los costes directos de adquisición de los fármacos. Se realizó un análisis de sensibilidad determinístico para comprobar la robustez de los resultados. Resultados: La SLP obtenida en los ensayos clínicos de los tratamientos cis/pem, cis/gem/bev y carb/pac/bev fue de: 6,9, 6,7 y 6,2 meses, respectivamente. En base a nuestro modelo, el coste medio del tratamiento por paciente para estos esquemas fue de 19.942 €, 15.594 € y 36.095 €, respectivamente.

    Commercial paraffin wax used by Bolsius Nederland B.V. for manufacturing various kinds of candles was applied as a phase-change material (PCM) for cooling a 28 W high-power light emitting diode (LED) panel during its operation. The main problem arising during operation of an LED is thermal management. According to the manufacturer's datasheet specifications (BioSolution Ltd. www.biosolution.pl, the operating temperature range for the LED street lamp UL28W is (-30 {°}C) to (+40 {°}C). The object of the present study was an LED panel containing 28 pieces of high-power 1W LEDs connected in series (4 LEDs in each of the 7 rows) mounted on an aluminum plate of dimensions 80 mm by 135 mm. The tested aluminum plate was placed in a block made of aluminum with a hollow compartment containing Bolsius paraffin wax of density 914 kg\\cdot m^{-3} at room temperature. Temperatures were recorded using K-type thermocouples at selected locations of the tested LED panel for several values of the power supplied to it, while utilizing PCM and without it. As the manufacturer of Bolsius wax candles does not provide any data on the thermal properties of the material used, it was necessary to carry out micro-calorimetric research. Thermophysical properties of the paraffin wax such as the apparent specific heat, enthalpy of phase transition and temperature of phase change transition during heating and cooling were determined using the Netzsch DSC 214 Polyma. The Netzsch TG 209F3 Tarsus was used for TG/DTG measurements. DSC investigations revealed the following thermal transitions taking place during the first heating: solid-solid transition (onset 30.4 {°}C, peak at 40.9 {°}C), solid-liquid transition (onset 47.7 {°}C, peak at 54.9 {°}C, end at 58.3 {°}C), latent heat of energy storage 201 J\\cdot g^{-1}, apparent specific heat corresponding to peak at 41.5 {°}C (5.498 J\\cdot g^{-1}\\cdot K^{-1}).

    Bank filtrated water has been used in developed countries such as United States, France, Germany, Austria, Nederland and so on. In Korea, most of the drinking water is provided from the surface water. However, drinking water acquisition is becoming difficult due to the degradation of surface water quality. In special, the quality of drinking water source is much lower in downstream area than in upstream area. Thus, the use of bank filtrated water is getting attracted by central and local governments in Korea. The bank filtrated water was surveyed in the areas of Yeongsan river, Nakdong river, Geum river and Han river. Up to present, however, the downstream areas of Nakdong river are most suitable places to apply the bank filtration system. This study investigates hydrogeological characteristics of bank-storage area located in Daesan- Myeon, Changwon city, adjacent the downstream of Nakdong river. Changwon city is the capital city of Gyeongsangnam-Do province. Changwon city uses water derived from Nakdong river as municipal water. However, the quantity and quality of the river water are gradually decreased. Thus, Changwon city developed two sites of bank filtration system in Daesan-myeon and Buk-myeon. Pumping rate is 2,000m3/day at present and will be increased to 60,000m3/day in Daesan-myeon site at the end of the first stage of the project. For the study, we conducted pumping tests four times on seven pumping wells (PW1, PW2, PW3, PW4, PW5, PW6, and PW7) and twelve drill holes (BH-2, OW2-OW12) in the area of 370 m x 100 m. Pumping wells PW1 and PW2 were drilled in 1999 by Samjung Engineering Co. and pumping wells PW3, PW4, PW5, PW6 and PW7 were drilled in 2000 by Donga Construction Co. and Daeduk Gongyeong Co. The pumping wells are located at 45-110 meters from Nakdong riverside. The geology of the study area is composed of volcanic rocks (Palryeongsan tuff and Jusasan andesitic rock) and alluvium.

  12. Scatterometry

    Een veelheid aan meteorologische metingen is dagelijks beschikbaar. De meeste van deze waarnemingen bevinden zich echter boven land, en met name windwaarnemingen boven de (Noord Atlantische) oceaan zijn schaars. Bij een westelijke luchtstroming is dit een duidelijke beperking voor de weers- en golfverwachtingen ten behoeve van Nederland. Juist dan is het gevaar voor bijvoorbeeld storm of overstroming het grootst. Ook in het aardse klimaatsysteem speelt de wind aan het oppervlak een grote rol en is de belangrijkste factor voor de aandrijving van de oceaancirculatie. De oceaancirculatie op zijn beurt is cruciaal voor de verschijnselen die samenhangen met bijvoorbeeld El Niño. Dit proefschift gaat over het scatterometer instrument dat vanuit de ruimte, zelfs onder een wolkendek, nauwkeurige en betrouwbare informatie geeft over de wind aan het oceaanoppervlak met een hoge mate van ruimtelijke consistentie. Tijdens de tweede wereldoorlog werden radars aan boord van schepen veelvuldig gebruikt voor de opsporing van vijandige vaartuigen. Hierbij werd vastgesteld dat de detectie slechter werd naarmate de wind aan het zeeoppervlak groter was. Proefondervindelijk was hiermee het principe van een wind scatterometer aangetoond. Al snel ontwikkelde zich dan ook de idee de wind aan het zeeoppervlak te meten met behulp van radar. Vanuit een vliegtuig of een satelliet word dan een microgolfbundel onder een schuine hoek naar het zeeoppervlak gestuurd. De microgolfstraling, met gewoonlijk een golflengte van enkele centimeters, wordt verstrooid aan het ruwe oppervlak, en een klein gedeelte van de uitgezonden puls keert terug naar het detectorgedeelte van de scatterometer. Het fysische fenomeen van belang voor de werking van de scatterometer is de aanwezigheid van zogeheten capillaire gavitatiegolven op het zeeoppervlak. Deze golven hebben een golflengte van enkele centimeters en reageren vrijwel instantaan op de sterkte van de wind. De verstrooiing van microgolven is op zijn beurt
