Three-View Cloud Particle Imager (3V-CPI) for HIAPER

Paul Lawson & UCAR/NCAR-Earth Observing Laboratory
The Three-View Cloud Particle Imager (3V-CPI) is a combination of three imaging instruments. Two of them comprise a 2D-S instrument, in which two 2D probes image particles as they pass through beams that are oriented orthogonally to each other and the airflow. If particles also lie in the intersection of the sensitive areas of the two beams, they are seen by both 2D probes. In that case, the CPI is triggered to take a high-resolution...

A liaison between school children or a venue for professional travelling troupes, the theatre is designed to accommodate any size of performance. The integration of...

Foam separation of kraft mill effluents.

Donald Wayne Herchmiller
A laboratory investigation into foam separation processes, as applied to kraft pulping and bleaching effluents is described. Two methods, foam fractionation and ion flotation were tested in the laboratory. The procedures developed concentrated primarily on the removal of effluent colour because this property lent itself most readily to the available analytical methods, and because effluent colour removal presents one of the greatest waste water treatment problems facing the industry today. The foam fractionation technique was...

The development and evaluation of a nutrition education program for the third and fourth grades

Joyce Elizabeth MacKay
A nutrition education program for the third and fourth grade levels was developed within a sound educational structure, namely a systematic approach involving the five dimensions of motivation, concepts and generalizations, behavioral objectives, learning experiences and evaluation. To test the effectiveness of the nutrition education program, 117 children in two Vancouver schools participated in an experimental program. Fifty eight of these children were treated as two control groups, one group from each school. The other...

Gene expression in and development of trisomies of Drosophila melanogaster

Robert Harry Devlin
Drosophila melanoqaster individuals trisomic for an entire chromosome arm can survive to late stages of pupal development. To examine gene expression in these hyperploids, the levels of five enzymes whose structural genes are located on the left arm of chromosome two have been examined both in aneuploid and in diploid strains. Elevated levels of enzyme activity were observed in larvae possessing small segmental duplications for these genes. However, in 2L trisomies, the three distally mapping...

Investigating reduced rate of nitrogen application and delayed harvest of orchardgrass as a means of reducing the amount and altering the form of nitrogen ingested by lactating dairy cattle

Pierre Sebastiaan Groenenboom
Rations for lactating dairy cattle should supply adequate amounts of rumen undegradable protein without oversupplying rumen degradable protein. As forage grasses can supply too much rumen degradable protein to the ration, it is beneficial to produce forage grasses with higher proportions of rumen undegradable protein while maintaining acceptable yields and fibre levels. Forage grasses have many different types of protein with differing ability to withstand ruminal degradation. Non-protein nitrogen is very rapidly degraded in the...

Social interactions, wellbeing and health in the oldest old: what can we learn from daily life approaches?

Laura Marie Booi
Canada, like many Western societies, has an aging population. Past research indicates that social interactions are meaningfully associated with physical and mental health. Unfortunately, very few studies have included individuals older than 85 years. This is important because the Oldest Old are the fastest growing segment of the Canadian population. This study is based on a subsample of the Berlin Aging Study (N = 83; Mean age = 81.1 years) who participated in an intensive,...

Characterization of the MOS4-associated complex in plant defense signaling

Jacqueline Monaghan
The plant immune system is governed in part by Resistance (R) proteins that recognize pathogenic microorganisms and initiate enduring defense responses. While the terminal outputs of R protein activation are fairly well understood, information about signaling components involved in plant immunity is scarce. We previously showed that MODIFIER OF SNC1, 4 (MOS4) associates with the transcription factor AtCDC5 and the WD-40 protein PRL1 in vivo, forming the MOS4-Associated Complex (MAC). The MAC is required for...

S-PolKa: S-band/Ka-band Dual Polarization, Dual Wavelength Doppler Radar

UCAR/NCAR-Earth Observing Laboratory
NCAR/EOL's S-PolKa radar is an advanced, transportable, ground-based dual-polarimetric, dual-wavelength, Doppler weather radar. S-PolKa transmits 10 cm wavelength (S-band) and 0.86 cm wavelength (Ka-band) simultaneously with matched beamwidths and range resolution. The dual-polarimetric capabilities of S-PolKa lead to improved precipitation estimates over what is available on conventional radars, as well as real-time identification of hydrometeor types. The absolute phase measurements from S-PolKa can be used to compute and monitor in real time the low-level humidity...

The optical and electronic properties of these compounds were studied with absorption and emission spectroscopy, transient absorption spectroscopy, X-ray crystallography, and electrochemistry. The lowest energy absorption bands...

The politics of protection : conceptualizing climatic displacement and a global protection regime

Megan Aageson-Morlock
Climate change is anticipated to drive millions of people from their homes this century. Estimates indicate that between 200 and 250 million people may be displaced because of rising sea levels, desertification, and increased storm surges working in concert. At present, however, there is no protection regime, institutional mandate, or legal architecture capable of responding to the plight of climatically displaced persons (CDPs). Since 2007, a number of legal regimes have been proposed to provide...

Initial characterization of a new histone and role of methionine in protamine biosynthesis in trout testis

Donald Theodore Wigle
Histones are the basic proteins complexed with DNA in the chromosomes of eukaryotic organisms. A previously undescribed histone (histone T.) was discovered in chromatin prepared from rainbow trout (Salmo gairdnerii) testes. Histone T was purified by selective extraction and ion-exchange chromatography on CM-cellulose. The homogeneity of this protein was examined by polyacrylamide disc gel electrophoresis, SDS disc gel electrophoresis, urea starch gel electrophoresis and gel filtration chromatography. Histone T was homogeneous as judged by the...

Influences of weather and temperature on disease : implications for the population dynamics of western tent caterpillars

Leonardo Frid
Studies on insect population outbreaks have failed to identify a single, general cause for population cycles. However, few studies have considered how various factors may together cause periodic outbreaks. Here I consider how disease and weather might interact to cause population cycles of western tent caterpillars, Malacosoma californicum pluviale (Dyar). A multiple regression analysis indicates that nuclearpolyhedrovirus (NPV) prevalence in western tent caterpillar populations increases with both host density and hours of sunshine during the...

New methods for rapid radiohalogen labelling of organic molecules

Julius Alexander Balatoni
The aim of this study was to develop new and rapid procedures for the incorporation of short-lived radiobromine and radioiodine isotopes into organic compounds. This was accomplished by the electrophilic cleavage of tin-carbon bonds with BrCl and ICl generated in-situ from bromide and iodide, respectively, in the presence of an oxidizing agent. The vinyl-tin derivatives, [4], [8], [12], [17], [18] and [19], were prepared by treatment of the corresponding acetylenic compounds with tri-n-butyltin hydride, in...
