Neuronal Control Of Nematocyst Discharge In Hydra, A. A. Scappaticci Jr.

Open Access Dissertations

This dissertation research seeks to understand how the neuronal circuitry of the battery cell complex in hydra functions in order to accomplish the basic biological necessity of food acquisition through its effector organelles, the nematocysts. A behavioral assay was used to discharge individual nematocysts from the tentacles of Hydra vulgaris. Cnidocils were mechanically deflected using a piezoelectrically driven glass probe. Standard immunohistochemical methods were used to localize the N-methyl-D-aspartate receptor in hydras tissues. Desmonemes and stenoteles differentially responded to imposed forces on the cnidocil. Desmonemes discharged when the cnidocil was struck with a force of at least 3.7 × 10−3 …

The Indigenous Vote: Protecting Or Endangering Sovereignty?, David E. Wilkins

Jepson School of Leadership Studies articles, book chapters and other publications

Much ado has been made about the 2002 mid-term congressional and gubernatorial elections. Democrats are bemoaning the Republican's treble triumph—congressional control, an invigorated Bush administration, and conservative rule on the supreme court. Republicans are exulting in their perceived conservative mandate—to address the War on Terror, privatize Social Security, and roll back environmental regulations that are deemed overly restrictive of private and public property development. And the inconsistent American voter, depending on race, socio-economic status, and issue salience, seems either unenthusiastic, ambivalent, or wildly animated about politics.

Leptodactylus Mystacinus, M. M. Heyer, W. R. Heyer, Rafael O. De Sá

Biology Faculty Publications

Adult Leptodactylus mystacinus are of moderate size, the head is as wide as long, and the hind limbs are moderately short (see Table; Heyer and Thompson 2000 provided definitions of adult size and leg length categories for Leptodactylus). Male vocal sacs are not visible externally or at best are weakly expanded laterally and slightly darker than female throats. Male snouts are more spatulate than those of females. Male forearms are not hypertrophied. Males lack asperities on the thumbs and chest. One or two pairs of dorsolateral folds (indicated by dark/light outlining in indifferently preserved specimens) are present: one …

Regional Dispersal Of Daphnia Lumholtzi In North America Inferred From Issr Genetic Markers, G. Matthew Groves

Masters Theses

The exotic zooplankter Daphnia lumholtzi is believed to have been introduced into Fairfield Lake, TX in 1983. Since introduction, D. lumholtzi has spread throughout the Midwest and Southeast United States. Due to its large head and tail spines, it may be less susceptible than native species to predation and therefore pose a threat to aquatic ecosystems. Development of management practices calls for study of the dispersal and potential impact of D. lumholtzi on invaded ecosystems.

Inter-simple sequence repeat (ISSR) markers were used in an effort to determine dispersal patterns of D. lumholtzi. Previous studies have shown that ISSRs possess …

Behavioral Aspects Of Apolipoprotein E Knockout Mice, Melissa T. Litherland

Masters Theses

Apolipoprotein E (apoE) is a lipid transporting protein that has been shown to play a vital role in nerve repair and remodeling. Previous studies have shown that apoE is highly expressed in human and mouse olfactory bulbs. ApoE deficiency in apolipoprotein E knockout (apoE-KO) mice leads to considerable delay in olfactory nerve repair and deficits in olfactory functioning. Olfactory function is necessary for a number of social behaviors in mice. Loss of olfaction can greatly reduce social behaviors. Since apoE-KO mice display olfactory dysfunction, this deficit may result in alterations in social behavior. Olfactory function was assessed in apoE-KO mice …

John Punshon's Reasons For Hope: The Faith And Future Of The Friends Church*: A Review, Arthur O. Roberts

Quaker Religious Thought

In 1969 Elton Trueblood attributed the forfeiture of values in our culture in part to academicians and looked for recovery from the Christian intellectual who “has access to both the reasons of the heart and the reasons of the head” (A Place to Stand, p. 31). Friend John Punshon is such a Christian intellectual. His Reasons for Hope is a tract for the times. In language hortatory as well as analytical the book tugs at heart and mind. I found myself pondering it prayerfully as well as reading it critically.

Judges Of Character, Suzanna Sherry

Vanderbilt Law School Faculty Publications

For forty years, legal academics have been lost in a wilderness born of the countermajoritarian difficulty. Despite a two-century pedigree, we are still arguing about the legitimacy of judicial review and asking whether it is a curse or a blessing. Many of our most prominent constitutional scholars are mired in attempts to constrain judicial review so as to reconcile it with their idealized vision of a constitutional regime grounded in pure majoritarianism. None has succeeded. The few scholars who have attempted to move beyond the countermajoritarian difficulty face a different problem. As one scholar has argued, "[i]t takes a theory …

Linking Dispersal To Local Population Dynamics: A Case Study Using A Headwater Salamander System, Winsor H. Lowe

Dartmouth Scholarship

Dispersal can strongly influence local population dynamics and may be critical to species persistence in fragmented landscapes. Theory predicts that dispersal by resident stream organisms is necessary to offset the loss of individuals to downstream drift. However, there is a lack of empirical data linking dispersal and drift to local population dynamics in streams, leading to uncertainty regarding the general demographic significance of these processes and the power of drift to explain observed dispersal patterns. I assessed the contribution of dispersal along a first-order stream to population dynamics of the headwater salamander Gyrinophilus porphyriticus (Plethodontidae). I conducted mark–recapture surveys of …

Every Day Is Halloween: A Goth Primer For Law Enforcement, Gordon A. Crews

Criminal Justice Faculty Publications

The following article is based upon field research conducted by Dr. Gordon A. Crews dealing with juveniles and young adults involved in the “Goth” lifestyle across the United States. This research is part of his ongoing efforts over the last decade to examine the impacts of alternative lifestyles, beliefs, and practices upon juvenile delinquency and violence. Most of the information in this article has been derived from face-to-face interviews with individuals aged 13 to 39 years of age proclaiming to be Goth, Vampires, Satanists, Pagans, Wiccans, New Agers, Druids, and a myriad of other occult-based identities.

Numerical And Granulometric Approaches To Geophysical Granular Flows , Sébastien Dartevelle

Dissertations, Master's Theses and Master's Reports - Open

Volcanic ash clouds can be fed by an upward-directed eruption column (Plinian column) or by elutriation from extensive pyroclastic-flows (coignimbrite cloud). For large-scale eruptions, there is considerable uncertainty about which mechanism is dominant. Here we analyze in a novel way a comprehensive grainsize database for pyroclastic deposits. We demonstrate that the Mount Pinatubo climactic eruption deposits were substantially derived from coignimbrite clouds, and not only by a Plinian cloud as generally thought. Coignimbrite ash-fall deposits are much richer in breathable <10 m ash (5–25 wt%) than pure Plinian ash at most distances from the source volcano. We also show that coignimbrite ash clouds, as at Pinatubo, are expected to be more water rich than Plinian clouds, leading to removal of more HCl prior to stratospheric injection, thereby reducing their atmospheric impact.

Reduction Of High Soil Test Phosphorus By Corn And Soybean Varieties, Bahman Eghball, J.F. Shanahan, Gary E. Varvel, John Gilley

Department of Agronomy and Horticulture: Faculty Publications

Soils with high levels of P can contribute to excess P in runoff and subsequently pollute the surface water. Excess P in the soil can be removed from the system by harvesting crops. The objectives of this study were to evaluate corn (Zea mays L.) P removal effects on soil P reduction, and to evaluate various corn hybrids and soybean [Glycine max (L.) Merr.] varieties for differences in grain P concentration and P removal. Soil with varying P levels as a result of annual or biennial beef cattle (Bos taurus) feedlot manure or compost appli- enough …

Surveys For Gray Whales, Eschrichtius Robustus, Near Cape Caution, British Columbia, Summer 2003, William Megill, Lei Lani Stelle, Becky Woodward

Articles

The Coastal Ecosystems Research Foundation conducted several surveys for gray whales on the southern Central Coast of British Columbia during the summer of 2003. Three surveys were conducted in CERF’s usual study area near Cape Caution, and three along the west coast of Calvert Island. Additional shorter surveys were also conducted of the Rivers Inlet / Smith Sound region north of Cape Caution. A total of 50 animals were identified from the pigmentation on their flanks. Twelve of these were new to the area in 2003. All but three were photographed. The animals not photographed (due to a camera malfunction) …
