Odonata Collected with a Mist Net in Baraga County, Michigan, including a New Record for the Upper Peninsula

Excerpt: In the summer of 1966, a study of the interrelation of birds and forest insects was initiated at Michigan Technological University. Japanese mist nets were used, among other methods, to make population estimates of birds. When checking the nets for trapped birds , Odonata were often found in the pockets, We were thus able to compile a list of Odonata frequenting the shores of Little Lake, Baraga County, Michigan. The lake, actually a small stagnant basin of water not exceeding a foot in depth in dry years, is located on the Baraga Plains, approximately five miles west of Michigan Tech\u27s Ford Forestry Center

Studies of the interplanetary magnetic field: IMP's to Voyager

During the last two decades, spacecraft projects and individual experiments for which Frank McDonald was a leader have contributed very significantly to the current understanding of the structure of interplanetary space and the correlation between solar and interplanetary disturbances. Studies on the IMP, HELIOS, and Pioneer spin-stabilized spacecraft and the larger attitude-stabilized Voyager spacecraft have provided data sets from which the modern view of the heliosphere has evolved. That concept in which the inner solar system is shown to be dominated by individual streams associated with specific source regions on the Sun is illustrated. As these high-speed streams overtake the preexisting solar plasma, they coalesce and modify the characteristics so that at larger heliocentric distances, these disturbances appear as radially propagating concentric shells of compressed magnetic fields and enhanced fluctuation

Spin Clustering of Accreting X-ray Neutron Stars as Possible Evidence of Quark Matter

A neutron star in binary orbit with a low-mass non-degenerate companion becomes a source of x-rays with millisecond variability when mass accretion spins it up. Centrifugally driven changes in density profile may initiate a phase transition in a growing region of the core parallel to what may take place in an isolated millisecond pulsar, but in reverse. Such a star will spend a longer time in the spin frequency range over which the transition occurs than elsewhere because the change of phase, paced by the spinup rate, is accompanied by a growth in the moment of inertia. The population of accreters will exhibit a clustering in the critical frequency range. A phase change triggered by changing spin and the accompanying adjustment of moment of inertia has its analogue in rotating nuclei.Comment: 5 pages (AIPproc latex) 6 figures.

Compassed about with so great a cloud: the witnesses of Scottish episcopal acta before ca 1250

This article is the result of examining the witnesses to some 600 episcopal acta. Despite the unequal incidence of survival from one diocese to another and the difficulty of identifying those men who had no surname, it is possible to draw some conclusions from this type of evidence. Some-thing can be said about the bishops' clerks and chaplains, other members of their households and their relatives. There is evidence of considerable continuity of personnel from one episcopate to the next. Promotion, including movement to another diocese, can be traced, as can the arrival, growth in numbers and careers of magistri. Surnames allow a consider-ation of the origins of witnesses. Some light is thrown on the growth of cathedral chapters, the introduction of bishops' officials, the role of the Céli Dé, and on clerical dynasties, illegitimacy and pluralism. The Scottish Church is seen to be integrated into the wider Western Church

Mansel: God and politics

Henry Longueville Mansel (1820-71), Anglican theologian and philosopher, hastypically been remembered as a Kantian agnostic whose ideas led to those of Herbert Spencer. This thesis provides a critical challenge to this picture, and offers a thorough revisioning of Mansel’s theology in context. First, concerning misrepresentation, I argue it was Spencer himself who, having had a youthful relationship with Mansel’s sister Katherine, developed a prejudice against him, distorted the reception of his work, and promoted the caricature image of Mansel as an unwitting agnostic and “Kantist”. With the help of Liberals such as Goldwin Smith and Leslie Stephen, Spencer’s portrayal has stuck. I refute this picture and offer an alternative reading of Mansel. Second, concerning personalism, I show that Mansel was essentially a theistic personalist, indebted to the traditions of Bishop Browne, Bishop Butler, and Scottish common sense philosophy. Mansel represents a mid-Victorian example of “IThou” philosophical theology, grounded in the religious practice of Christian prayer. Mansel’s theistic personalism had much in common with Newman’s theology, and I explore the ways in which Newman’s Grammar of Assent was written in response to Mansel’s Bampton Lectures. Third, concerning politics, I argue that Spencer’s distorted picture of Mansel as a Kantian agnostic served the political interests of partisan Liberals, and was aggressively spread by them because of Mansel’s own Tory commitments. Located in context, Mansel, is here interpreted with reference to key personal relationships and personal networks, including his connection with leading Tories, such as Lord Carnarvon and Benjamin Disraeli. Crucially, I interpret his controversies with Frederick Denison Maurice and John Stuart Mill with reference to the political events of 1859 and 1865. These controversies were simultaneously religious and political, and receive a careful contextual reading

Concentrations of Polychlorinated Biphenyls (PCBs), Polychlorinated Dibenzo-p-dioxins and Furans (PCDD/Fs), and Polybrominated Diphenyl Ethers (PBDEs) as Functions of Sample Depth in Killer Whale (Orcinus orca) Blubber

Concentrations of polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), and polybrominated diphenyl ethers (PBDEs) were examined as a function of depth in killer whale (Orcinus orca) blubber samples. Lipid-normalized concentrations of PCBs, PCDD/Fs, and PBDEs did not display significant variation with depth in three distinct blubber layers (outer, central, and inner). Significantly more variation in contaminant concentrations were observed with depth on a wet weight basis for the killer whale sample. The current study indicates that non-invasive microdart biopsy sampling methods commonly used for monitoring contaminants in marine mammals yield representative details on contaminant burdens for chlorinated and brominated aromatic compounds in marine mammal blubber, regardless of the quantity and type of blubber sampled, provided that lipid normalization is performed on resulting analytical determinations
