Evaluation of Plantings for Wildlife on a Power Line Right of Way in Southern Arkansas

The combination of types of land preparation and species of plants seeded along a power line right-of-way was evaluated in terms of the effects upon wildlife. Relative population densities of plants, birds, and mammals were determined for each of the areas under study. A study of the reduction in maintenance costs in relation to the initial investment for preparation and seeding of the land was mad

Piezoelectricity of Cholesteric Elastomers

We consider theoretically the properties of piezoelectricity in cholesteric elastomers. We deduce using symmetry considerations the piezoelectric contributions to the free energy in the context of a coarse-grained description of the material. In contrast to previous work we find that compressions or elongations of the material along the pitch axis do not produce a piezoelectric response, in agreement with fundamental symmetry considerations. Rather only suitable shear strains or local rotations produce a polarization. We propose some molecular mechanisms to explain these effects.Comment: 11 pages, 1 Postscript figure; Late

\u3ci\u3eTomicus Piniperda\u3c/i\u3e (Coleoptera: Scolytidae) Reproduction and Behavior on Scotch Pine Christmas Trees Taken Indoors

Tomicus piniperda, the pine shoot beetle, is an exotic insect that was first found in North America in 1992. A federal quarantine currently restricts movement of pine products, including Christmas trees, from infested to uninfested counties. We conducted a study to determine if T. piniperda would re- produce in Christmas trees that were cut and taken indoors during the Christmas season. Twelve Scotch pine, Pinus sylvestris, Christmas trees infested with overwintering T. piniperda beetles were cut in Indiana in early December 1993 and taken to Michigan. Four trees were dissected immediately, while the other 8 trees were taken indoors, placed in tree stands, and watered regularly. After 4 weeks indoors, 4 trees were dissected, and the other 4 were placed outdoors in Michigan for 7 weeks. Upon dissection, all overwintering sites occurred along the lower trunk within the first 40 em of the soil line; 81% were found within 10 em of the soil line. Adults collected from the 4 trees dissected in December produced viable progeny adults when placed on Scotch pine logs in the laboratory. Overwintering beetles became active and laid eggs in 4 of the 8 trees that had been taken indoors. All adults and progeny found in the 4 trees that had been placed outdoors for 7 weeks during cold January and February temperatures were dead. Overall, T. piniperda can become active and breed in Christmas trees that are cut and taken indoors in December. Tomicus piniperda survival in trees that are discarded outdoors at the end of the Christmas season will depend largely on the prevailing temperatures

Learning from those "imitative" Japanese : Edward S. Morse and the civilization of the Mikado's empire

Already in the twelfth century, men canvassed different views on the ways in which they thought lordship ought to be exercised. They used their picture of how an idealised "Good Lord" -- a familiar label in later times -- comported himself to assess the treatment they actually received from their lords. This Good Lordship had both Positive and Negative aspects: the "good lord" maintained his vassals in their honours and renounced his right to revoke grants afterwards. One excellent way to study the pursuit of this double ideal is through the language of charters, more particularly through the warranty clauses by which Good Lordship was often implemented. The transformation of warranty into its familiar Common-Law shape reflects corresponding and complex changes in both lord-vassal relations and the role of the King and his justice. Warranty actually began as a security device, designed to keep men to their word, and is found used in this sense over wide areas of sub- Carolingian Europe. It was probably imported to England by the French, and can be seen in twelfth-century charters progressively superseding other forms of words to become the classic "guarantee" of Good Lordship. In this manner it came by 1200 to be virtually equated with the lordship it had originally been used to enforce. Warranty was lordship seen from the vassal's point of view, that is, tenant-right. Despite this origin in very personal relations, warranty probably always created between the parties' heirs some kind of obligation, which sharpened and was made infinitely more clear-cut with the emergence of full legal inheritance rights. Warranty swelled to full tenant-right, a full guarantee of the Right to Good Lordship. As the heir's claim grew into an enforceable right of inheritance through increasing access to remedies by royal justice, and because such justice tended to strict construction, warranty became a contractual addition to which claimants had to prove their entitlement. The narrative of legal change from 1150 argues for gradual evolution but also suggests 1153-4 as the decisive turning-point in this development. Detailed (sometimes technical) examination of evidence for some relevant cases, royal writs concerning warranty and the turning-point of 1153-4 is reserved for three appendixes

Chapter IV-1 - Griffis in Tokyo

In which William E. Griffis spends more than two years in Tokyo, teaching science, promoting Christian activities, and writing on Japan for American publications, and how his sister Maggie comes to live with him, and how during those two years he keeps longing for the traditional Japan that he is helping to destroy, the Japan he so precipitously fled from in Fukui

Eugenics as wrongful

In a landmark legal case in 1996, eugenics survivor Leilani Muir successfully sued the province of Alberta for wrongful confinement and sterilization. The legal finding implied that Ms. Muir should never have been institutionalized at the Provincial Training School of Alberta as a “moron” and sterilized under the Sexual Sterilization Act of Alberta. The trial itself revealed many unsettling features of the province’s practice of eugenics, raising questions about how a seemingly large number of people, like Ms. Muir, who were not mentally defective, could have been wrongfully confined at an institution for the feeble-minded, and subsequently sterilized on eugenic grounds. Employing a three-agent model of wrongful accusation and conceiving of eugenics as wrongful more generally may help in understanding the operation of eugenic practices, such as institutionalization and sterilization, both in Western Canada and elsewhere. Eugenic practice involves a form of wrongful accusation that marks a significant departure from eugenic ideology

Synergistic degradation of lignocellulose by fungi and bacteria in boreal forest soil

Thesis (M.S.) University of Alaska Fairbanks, 2015Boreal forests contain an estimated 28% of the world's soil carbon, and currently act as a significant global carbon sink. Plant-derived lignocellulose is a major component of soil carbon, and its decomposition is dependent on soil bacteria and fungi. In order to predict the fate of this soil carbon and its potential feedbacks to climate change, the identities, activity, and interactions of soil microbial decomposer communities must be better understood. This study used stable isotope probing (SIP) with ¹³C-labeled lignocellulose and two of its constituents, cellulose and vanillin, to identify microbes responsible for the processing of lignocellulose-derived carbon and examine the specific roles that they perform. Results indicate that multiple taxa are involved in lignocellulose processing, and that certain taxa target specific portions of the lignocellulose macromolecule; specifically, fungi dominate the degradation of lignocellulose and cellulose macromolecules, while bacteria scavenge aromatic lignocellulose monomers. Major fungal taxa involved in lignocellulose degradation include Ceratobasidium, Geomyces, and Sebacina, among others. Bacterial taxa processing lignocellulose and cellulose included Cellvibrio and Mesorhizobium in high abundance relative to other taxa, although Burkholderia were the primary vanillin consumers. These results elucidate some of the major players in lignocellulose decomposition and their specific roles in boreal forest soil. This information provides knowledge of small-scale microbial processes that dictate ecosystem-level carbon cycling, and can assist in predictions of the fate of boreal forest carbon stocks
