Improved spectroscopy of molecular ions in the mid-infrared with up-conversion detection
No full text"Heterodyne detection, velocity modulation, and cavity enhancement are useful tools for observing rovibrational transitions of important molecular ions.\footnote{K.N. Crabtree, J.N. Hodges, B.M. Siller, A.J. Perry, J.E. Kelly, P.A. Jenkins II, and B.J. McCall, Chem. Phys. Lett. 551 (2012) 1-6.} We have utilized these methods to investigate a number of molecular ions, such as H, CH, HeH, and OH.\footnote{A.J. Perry, J.N. Hodges, C.R. Markus, G.S. Kocheril, and B.J. McCall, J. Mol. Spec. 317 (2015) 71-73.}\footnote{J.N. Hodges, A.J. Perry, P.A. Jenkins II, B.M. Siller, and B.J. McCall, J. Chem. Phys. 139 (2013) 164291.}\footnote{A.J. Perry, J.N. Hodges, C.R. Markus, G.S. Kocheril, and B.J. McCall. 2014, J. Chem. Phys. 141, 101101}\footnote{C.R. Markus, J.N. Hodges, A.J. Perry, G.S. Kocheril, H.S.P. M{\""u}ller, and B.J. McCall, Astrophys. J. 817 (2016) 138.} In the past, parasitic etalons and the lack of fast and sensitive detectors in the mid-infrared have limited the number of transitions we could measure with MHz-level precision. Recently, we have significantly reduced the amplitude of unwanted interference fringes with a Brewster-plate spoiler. We have also developed a detection scheme which up-converts the mid-infrared light with difference frequency generation which allows the use of a faster and more sensitive avalanche photodetector. The higher detection bandwidth allows for optimized heterodyne detection at higher modulation frequencies. The overall gain in signal-to-noise from both improvements will enable extensive high-precision line lists of molecular ions and searches for previously unobserved transitions."Made available in DSpace on 2017-01-26T21:38:42Z (GMT).

The prints of J.N. Darling
No full textThis is the bibliographic record of the book entitled The Prints of J.N. Darling by Amy N. Worthen that is in the NCTC Conservation Library collection. J.N. "Ding" Darling is an extraordinary example of the artist at work in conservation education. After he guided the funding for the Migratory Bird Hunting Stamp Act through Congress, Ding Darling sketched his concept of a suitable image for the First Federal Duck Stamp. Bibliographic record: Personal Author: Worthen, Amy N. Title: The prints of J.N. Darling / Amy N. Worthen ; Brunnier Gallery and Museum. Edition: 1st Iowa State University Press ed. Publication info: Ames, Iowa : Iowa State University Press, 1991. Physical descrip: 126 p. ; 29 cm. General Note: "First published in 1984 on the occasion of the exhibition The Prints of J.N. Darling, August 29-October 7, 1984"--T.p. verso
Mitigation of indirect environmental effects of GM crops
No full textCurrently, the UK has no procedure for the approval of novel agricultural practices that is based on environmental risk management principles. Here, we make a first application of the ‘bow-tie’ risk management approach in agriculture, for assessment of land use changes, in a case study of the introduction of genetically modified herbicide tolerant (GMHT) sugar beet. There are agronomic and economic benefits, but indirect environmental harm from increased weed control is a hazard. The Farm Scale Evaluation (FSE) trials demonstrated reduced broad-leaved weed biomass and seed production at the field scale. The simplest mitigation measure is to leave a proportion of rows unsprayed in each GMHT crop field. Our calculations, based on FSE data, show that a maximum of 2% of field area left unsprayed is required to mitigate weed seed production and 4% to mitigate weed biomass production. Tilled margin effects could simply be mitigated by increasing the margin width from 0.5 to 1.5m. Such changes are cheap and simple to implement in farming practices. This case study demonstrates the usefulness of the bow-tie risk management approach and the transparency with which hazards can be addressed. If adopted generally, it would help to enable agriculture to adopt new practices with due environmental precaution

Bouwen met de natuur
No full textEerste plan van Svasek voor een kustuitbreiding tussen Hoek van Holland en Scheveningen, gebruikmakend van natuurlijke processsen. In dit document is voor het eerst de term "bouwen met de natuur" (building with nature") gebruikt. " De hier gepresenteerde beschouwingen hebben als doel een bijdrage te leveren aan de thans opgeleefde diskussie over de kustlokaties als onderdeel van de regionale en provinciale ruimtelijke ordening. Gepoogd is om van het begin af aan het natuurgebeuren ten grondslag te leggen aan de planning. De kennis van de kustmorfologie is in Nederland in voldoende mate aanwezig om bij het ontwerpen van kustplannen met de natuur en niet tegen de natuur in te kunnen werken.
