Infrared radiometric technique in temperature measurement

One class of commercially available imaging infrared radiometers using cooled detectors is sensitive to radiation over the 3 to 12 micron wavelength band. Spectral filters can tailor instrument sensitivity to specific regions where the target exhibits optimum radiance. The broadband spectral response coupled with real time two-dimensional imaging and emittance/background temperature corrections make the instruments useful for remote measurement of surface temperatures from -20 C to +1500 C. Commonly used radiometric techniques and assumptions are discussed, and performance specifications for a typical modern commercial instrument are presented. The potential usefulness of an imaging infrared radiometer in space laboratories is highlighted through examples of research, nondestructive evaluation, safety, and routine maintenance applications. Future improvements in instrument design and application of the radiometric technique are discussed

A Report on One Year\u27s Experience as the Advisor to the Board of Directors of Binational Center in Merida, Yucatan, Mexico

It is my intent, in writing this, my Independent Professional Project, to present to the reader through an assortment of facts, ideas, experiences and evaluations an overview of the history, components and present status of binational centers and of the INSTITUTO BENJAMIN FRANKLIN DE YUCATAN, A.C. ; a rather in-depth discussion of the work of the Advisor to the Board of Directors ( the equivalent of Executive or Administrative Director in most other centers ) during the 1974-75 academic year, including his duties, goals and frustrations (often caused by problems of communication, culture and/or politics), and his relationship with the Board of Directors, Mexican and American governments, teachers and others. This paper may be of at least partial interest to those concerned with binational centers, administration, United States foreign policy, and the teaching of language and culture. It also should be of interest to those who are considering applying for the position of Executive Director of a binational center or to those who may want to do so in the future

Genome Assembly Improvement and Mapping Convergently Evolved Skeletal Traits in Sticklebacks with Genotyping-by-Sequencing.

Marine populations of the threespine stickleback (Gasterosteus aculeatus) have repeatedly colonized and rapidly adapted to freshwater habitats, providing a powerful system to map the genetic architecture of evolved traits. Here, we developed and applied a binned genotyping-by-sequencing (GBS) method to build dense genome-wide linkage maps of sticklebacks using two large marine by freshwater F2 crosses of more than 350 fish each. The resulting linkage maps significantly improve the genome assembly by anchoring 78 new scaffolds to chromosomes, reorienting 40 scaffolds, and rearranging scaffolds in 4 locations. In the revised genome assembly, 94.6% of the assembly was anchored to a chromosome. To assess linkage map quality, we mapped quantitative trait loci (QTL) controlling lateral plate number, which mapped as expected to a 200-kb genomic region containing Ectodysplasin, as well as a chromosome 7 QTL overlapping a previously identified modifier QTL. Finally, we mapped eight QTL controlling convergently evolved reductions in gill raker length in the two crosses, which revealed that this classic adaptive trait has a surprisingly modular and nonparallel genetic basis

An updated assessment of the Agulhas sole resource, Austroglossus pectoralis.

Butterworth and Glazer (2014) reported results from the application of a simple form of the dynamic Schaefer model to account for a large drop in sole CPUE over the period 2009-2013. The two hypotheses considered were (i) the drop in CPUE was a consequence of decreasing catchability and (ii) the drop in CPUE was a consequence of decreasing productivity. The model was applied again in 2016 (Butterworth et al., 2016) and 2017 (Glazer et al., 2017). Results from the assessment conducted in 2017 yielded more positive future projections for the most pessimistic scenario (a decrease in productivity, where effort remains at its current reduced level into the future). Recent biomasses were estimated to be higher and projected to decrease more slowly if the 2013 effort level was maintained. Given that data are now available for 2017, the assessment model has once again been updated, with results reported here. These point to yet a more positive resource situation

Exploratory analyses of the Agulhas sole assessment

A number of different production model approaches are considered for assessment of the Agulhas sole resource, Stationary models, either with observation error only estimation, or adding annual process error, exhibit systematic patterns in residuals. The best approach seems to be to postulate a non-stationary situation, with some change in the dynamics of the resource (or equivalently in the fishery catchability q) in the new century. Some initial comments are made as regards the next steps needed to advance this approach further

Further sole dynamic Schaefer production model results

The sole resource is modelled by a dynamic Schaefer production model which allows for a drop in the value of the intrinsic growth rate parameter from 2000 onwards. The model is fit to the available CPUE and survey abundance indices. These data are not sufficiently informative to be able to distinguish amongst fairly wide ranges of pre- and post-2000 intrinsic growth rate parameters. Nevertheless, all suggest that the sole resource has never been substantially depleted (being well above its MSY level), and furthermore that the current replacement yield and MSY are reasonably robustly estimated in the ranges of 300-400 and 500-650 mt respectively

Faculty Mentoring At A Distance: Coming Together In The Virtual Community

This mixed-methods study explores how faculty in a virtual university experience the role of mentor working with doctoral students at a distance. This study uses faculty narratives to identify faculty actions that might be different from mentoring traditional doctoral students in a face to face program. In the new working adult universities, learners are not necessarily seeking initial careers through doctoral study but are enhancing established careers. The study investigates the mentoring skills on line faculty bring to the virtual learning space and describes how a graduate faculty teaching in a virtual learning space perform the role of mentor
