Hylopetes magistri, new name for Hylopetes debruijni Reumer & Van den Hoek Ostende, 2003, preoccupied
No full textIn 2003, we published a new species of Hylopetes, H. debruijni,
from the early Pleistocene locality of Tegelen, The Netherlands
(Reumer and Van den Hoek Ostende, 2003). This publication
appeared in a special volume in honor of Hans de Bruijn, which
contained the proceedings of congress in Utrecht (17–19 May
2001) on the occasion of the 70th birthday of our esteemed
colleague. While still in press, our publication was overtaken
by a paper by Mein and Ginsburg (2002), who, unaware of our
manuscript, also named a species of Hylopetes in honor of Hans
de Bruijn. The type locality of H. debruijni Mein & Ginsburg,
2002, is the middle Miocene fissure filling La Grive M in France.
The French material clearly represents a different species than
the Dutch finds. Therefore, we conclude that, unfortunately, we
published a name that was already preoccupied.
Daxner-H¨ ock (2004) tentatively assigned the Dutch species to
her new genus Neopetes, creating the new combination N. debruijni
(Reumer and Van den Hoek Ostende, 2003). This, however,
is of no consequence to the homonomy of the two species,
as the ICZN specifically defines a primary homonym as identical
species-group names for different taxa originally combined
with the same generic name. As a primary homonym, H. debruijni
Reumer & Van den Hoek Ostende, 2003, is permanently invalid
(ICZN 1999:art 57.2). Therefore, we propose Hylopetes magistri
new name for Hylopetes debruijni Reumer & Van den Hoek Ostende,
2003, preoccupied by Hylopetes debruijni Mein & Ginsburg,
2002. We consider assignation of the species magistri to the
genus Neopetesas proposed by Daxner-H¨ ock (2004) premature,
as this would first require direct comparison of the Dutch material
to the type species of that genus. The specific name (magistri

from Latin = of the master) mirrors our original intent to name
the species after Hans de Bruijn, and stresses that the maestro
has been instrumental in shaping the career of many palaeontologists,

Verslag van de studiedag 'dynamisch kustbeheer' - 22 september 1998 te Hoek van Holland
No full textHet versterken van de natuurlijke dynamiek in de zeereep is één van de actiepunten uit de tweede kustnota (Kustbalans1995). Op een eerdere studiedag in 1996 is aan de hand van de eerste praktijkervaringen ingegaan op (initiërende) maatregelen, mogelijke effecten en de monitoring hiervan. Inmiddels is er echter meer ervaring opgedaan in grote en kleine projecten en leek het een goed moment om de huidige ervaringen uit te wisselen. Op initiatief van de TAW-C heeft de Dienst Weg- en Waterbouwkunde daarom een tweede studiedag georganiseerd voor de diverse beheerders en belanghebbenden in het duingebied. In de ochtend is dynamisch kustbeheer in een aantal lezingen van Verschillende kanten belicht. In de eerste twee lezingen van P. Jungerius en G. van den Nieuwendijk stonden experimenten en onderzoeksresultaten centraal. In de lezingen van H. de Kruik en J. de Win kwamen de ruimtelijke ordening en kustvisies aan bod. P. Teunissen lichtte de stand van zaken toe omtrent bouwen in de kustzone. In de middag is het Masterplan Hoek van Holland toegelicht door M. Roukens en zijn verschillende locaties bezocht. Naast het leveren van informatie middels bovengenoemde lezingen was een belangrijke doelstelling van de dag het bevorderen van de onderlinge contacten en het (informeel) uitwisselen van ervaringen met dynamisch kustbeheer. De dag werd afgesloten met een korte discussie onder leiding van de dagvoorzitter W. van der Kleij. In dit verslag wordt een overzicht gegeven van de lezingen. Ook wordt een korte impressiegegeven van hoe de dag beleefd en gewaardeerd is, aan de hand van de uitkomsten van de evaluatieformulieren en enkele persoonlijke gesprekken.KWP-collectio
Irrigation water as a source of drinking water: is safe use possible?
No full textBACKGROUND: In arid and semi-arid countries there are often large areas where groundwater is brackish and where people have to obtain water from irrigation canals for all uses, including domestic ones. An alternative to drawing drinking water directly from irrigation canals or village water reservoirs is to use the water that has seeped from the irrigation canals and irrigated fields and that has formed a small layer of fresh water on top of the brackish groundwater. The objective of this study was to assess whether use of irrigation seepage water for drinking results in less diarrhoea than direct use of irrigation water and how irrigation water management would impact on health. METHODS: The study was undertaken in an irrigated area in the southern Punjab, Pakistan. Over a one-year period, drinking water sources used and diarrhoea episodes were recorded each day for all individuals of 200 households in 10 villages. Separate surveys were undertaken to collect information on hygiene behaviour, sanitary facilities, and socio-economic status. RESULTS: Seepage water was of much better quality than surface water, but this did not translate into less diarrhoea. This could only be partially explained by the generally poor quality of water in the in-house storage vessels, reflecting considerable in-house contamination of drinking water. Risk factors for diarrhoea were absence of a water connection and water storage facility, lack of a toilet, low standard of hygiene, and low socio-economic status. The association between water quality and diarrhoea varied by the level of water availability and the presence or absence of a toilet. Among people having a high quantity of water available and a toilet, the incidence rate of diarrhoea was higher when surface water was used for drinking than when seepage water was used (relative risk 1.68; 95% CI 1.31-2.15). For people with less water available the direction of the association between water quality and diarrhoea was different (relative risk 0.80; 95% CI 0.69-0.93). This indicates that good quality drinking water provides additional health benefits only when sufficient quantities of water and a toilet are available. In a multivariate analysis no association was found between water quality and diarrhoea but there was a significant effect of water quantity on diarrhoea which was to a large extent mediated through sanitation and hygiene behaviour. CONCLUSIONS: Increasing the availability of water in the house by having a household connection and a storage facility is the most important factor associated with reduced diarrhoea in this area. Safe use of canal irrigation water seems possible if households can pump seepage water to a large storage tank in their house and have a continuous water supply for sanitation and hygiene. Irrigation water management clearly has an impact on health and bridging the gap between the irrigation and drinking water supply sectors could provide important health benefits by taking into account the domestic water availability when managing irrigation water

Precipitation of supersaturated solute in H ion irradiated Fe-Au and Fe-Au-W alloys studied by positron annihilation spectroscopy
No full textThe effect of thermal aging of homogenized Fe-Au and Fe-Au-W alloys, irradiated at room temperature with hydrogen ions, was studied for an aging treatment at 300 °C for aging times up to 100 h. The aging behavior of the Fe-based alloys is compared to the results for pure Fe. The precipitation behavior of Au-rich and W-rich precipitates and its correlation to the H+ irradiation-induced defects is investigated by variable energy positron annihilation spectroscopy (VEPAS). The formation of open-volume defects after irradiation is monitored by an increase in the S parameter, while the recovery of the vacancy-like defects and the formation of precipitates are signalled by an increase in the W parameter. Au-rich precipitation continuously develops during long-term aging, as indicated by the increase in the W parameter. The change of the W parameter in the Fe-Au-W alloy is not only due to the effect of solute W on the Au precipitates, but also because of the interface of W-rich Laves phase with matrix.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Novel Aerospace MaterialsRST/Fundamental Aspects of Materials and Energ
Lydia H. Hart Diary
No full textDiary, 1823-1830, 1875 and loose papers 1813, 1831, and undated of Lydia H. Hart of Richmond, Virginia and later Walden, Orange County, New York. The Diary was started by Lydia H. Hart, the wife of Reverend William H. Hart, who was the rector of St. John’s Church in Richmond, VA and later St. Andrews Church in Walden, New York. Diary entries include day-to-day activities and meetings with local neighbors and church patron’s. These neighbors included Elizabeth Van Lew and her parents, which Lydia Hart writes about several times. Most dated entries also include discussion of specific bible verses or Rev. Hart’s sermons. Notable entries include a description of the funeral service for Rev. John Buchanan, former rector of St. John’s Church from 1795 to 1822. Diary entries are chronological and more frequent for 1823 and become less frequent in 1823. In 1828, Lydia Hart moved to New York and eventually to Walden, New York in May 1830.At the end of the diary entries is an entry form another author, possibly by Mary. W. Hart dated 1875. Lydia Hart died in 1831 and could not have made the entry.At the back of the diary and upside down to the diary entries are transcriptions of letters and poems of Lydia Hart’s to various newspapers and and personnel correspondence. Entries include a plea for support to the city of Richmond to take care of its ‘destitute children’, letters to the editor of local newspapers, and poems for the birth of a child or death of a patron.Loose papers include a letter dated Jan 8th 1813, a bequeath request from William H. Hart for the placement of a Tombstone for Lydia Hart, a table of contents for various letters or sermons, a letter from William Hart to a friend from Richmond, and 2 loose undated papers of unknown authorship. The letter from William Hart speaks of the events of Lydia’s death, and inquiries about events taking place in Richmond
1, 2-H shift in benzylchlorocarbene: isotope effect and influence of the solvent
No full textLaser flash photolysis of 3-chloro-3-benzyldiazirine and 3-chloro-3-(phenyldideuteriomethyl)diazirine in isooctane over the 60 to -80-degrees-C temperature range gives rise to curved Arrhenius plots for both 1,2-H and 1,2-D migration in benzylchlorcarbene. The k(H)/k(D) values increase smoothly from 0.87 to 2.62 when the temperature increases from -60 to +30-degrees-C. The k(H)/k(D) value is approximately 4 for most of the temperatures studied if a solvent correction is applied. Quantum mechanical tunnelling or the influence of the solvent may be a possible explanation for these observations.PT: J; CR: BONNEAU R, 1989, J AM CHEM SOC, V111, P5973 BONNEAU R, 1992, J PHOTOCH PHOTOBIO A, V68, P97 DIX EJ, 1993, J AM CHEM SOC, V115, P10424 EVANSECK JD, 1990, J PHYS CHEM-US, V94, P5518 GRAHAM WH, 1965, J AM CHEM SOC, V87, P4396 JACKSON JE, 1994, ADV CARBENE CHEM JONES M, 1980, REACTIVE INTERMEDIAT, V2 KIRMSE W, 1971, CARBENE CHEM LIU MTH, 1984, TETRAHEDRON, V40, P887 LIU MTH, 1990, J AM CHEM SOC, V112, P3915 LIU MTH, 1992, J PHOTOCH PHOTOBIO A, V63, P115 LIU MTH, 1992, J PHYS ORG CHEM, V15, P285 LIU MTH, 1994, RES CHEM INTERMEDIAT, V20, P195 MODARELLI DA, 1992, J AM CHEM SOC, V114, P7034 MOSS RA, 1992, TETRAHEDRON LETT, V33, P4287 MOSS RA, 1994, ADV CARBENE CHEM MUROV SL, 1973, HDB PHOTOCHEMISTRY NICKON A, 1993, ACCOUNTS CHEM RES, V26, P84 SALIS GA, 1968, J PHYS CHEM-US, V72, P752 SANDER W, 1994, UNPUB SCHAEFER HF, 1979, ACCOUNTS CHEM RES, V12, P288 SCHOLLER WW, 1989, HOUBEN WEYL METHODEN, P41 SHIMANOUCHI T, 1972, TABLES MOL VIBRATION, V1 SUGIYAMA MH, 1992, J AM CHEM SOC, V114, P966 WIERLACHER S, 1993, J AM CHEM SOC, V115, P8943; NR: 25; TC: 20; J9: J PHOTOCHEM PHOTOBIOL A-CHEM; PG: 5; GA: PV021Source type: Electronic(1

Study was part of PhD project of R. W. Hoek, which resulted in the PhD thesis: Hoek, R. W. (2020, 8 September). Re-examining the Relation Between Advertising Literacy and Children's Susceptibility to Advertising: An Indirect Measurement Approach. Behavioural Science Institute, Radboud University Nijmegen, the Netherlands.
The paper consists of three separate studies. Study 1 (N = 24, age: 10–12) describes the development of the Advertising Literacy Activation Task (ALAT) in which participants sort successive words in two categories: advertising or news. Studies 2 and 3 tested the ALAT on usability, reliability, predictive, and construct validity. In study 2 (N = 38, age: 10–12), participants were primed with a story about advertising or about news. Study 3 (N = 114, age: 7–13) used a similar design but with actual television commercials and news broadcast. Frequency and speed of categorizing conceptual and attitudinal words were analyzed with Bayesian statistics investigating effects of priming, dispositional advertising literacy, and their interactions. Results indicate that the ALAT is
a usable and reliable measurement instrument with good predictive validity, but with limited construct validity
