Observations of chemical releases from high flying aircraft

Barium and lithium vapors were released from sounding rockets in the thermosphere and observed from aboard the NASA Convair 990 at an altitude of 40,000 ft. The purpose of the releases was to (1) check out observational and operational procedures associated with the large high altitude barium release from a Scout rocket (BIC); (2) develop an all-weather technique for observing chemical releases; (3) evaluate methods of observing daytime releases, and (4) investigate the possibilities of observations from a manned satellite. The initial analysis indicates that the previous limitations on the usage of the vapor release method have been removed by the use of the aircraft and innovative photographic techniques. Methods of analysis and applications to the investigation of the thermosphere are discussed

Chromosome Number Changes Within Terrestrial Mammalian Families

This study comprehensively surveys diploid chromosome numbers across terrestrial mammal families using Wilson and Reeder’s classification. The data are organized around families, subfamilies, tribes, and genera to determine the extent of and identify trends and patterns in diploid number changes. A preliminary survey of nine established baramins revealed approximately 75% with significantly variable diploid numbers. An extensive compilation of chromosome numbers across 113 families that contain more than one species shows similar distribution with 75% variability using a strict definition of stability. There are many factors to examine such as speciose groups, high reproductive rates, and identifying parameters for defining stability. However, karyotype form diversity was found to be prevalent in spite of these considerations. Assuming that the rank of family approximates a baramin and using looser parameters to define constancy in diploid numbers, 62 families exhibit relative karyotype stability, 19 families with more extensive variation might be explained by multiple centric fusions and the remaining 48 families have unusual karyotype deviations

A Hierarchical Task Analysis of Commercial Distribution Driving in the UK

At the heart of distribution operations is an essential influence in the success or failure of achieving the triple bottom line of safety, efficiency, and environmental friendliness: commercial vehicle drivers, and the increasingly complex technology with which they interact. To the authors’ knowledge, no hierarchical task analysis exists for commercial distribution driving, and this gap suggests that the first step in clarifying these functional relationships is to fulfill the evident need for a HTA of the commercial driving task. Thus, relevant literature (e.g. the UK Driving Standards Agency; existing hierarchical task analysis of private vehicle driving) is consulted to review procedure and construct a hierarchical task analysis of commercial distribution driving, in accordance with UK standards for C, CE, C+1 and CE+1 licensed driving activities. Preliminary analysis indicates that successful completion of the commercial driving task is subject to a far more complex set of factors than that of private vehicle driving, many of which require input from actors across various contexts, and rely heavily on automated vehicle technology. At present there exists no comprehensive, standardized measure against which to evaluate the quality of content in commercial driver training, and much is left to the expertise and discretion of individual companies to determine content which will create and support an ‘effective’ driver. This hierarchical task analysis provides a normative characterization of commercial driving which informs driver training needs and course content, and supports industry expertise with a functional structure. Furthermore, this analysis may also serve as an input to a wide range of human factors analyses for effective system design
