A Vascular Flora Of Jackson County, Alabama, Kristin Renée Brodeur

Theses

The county is herein documented to support 1,272 species and infraspecific taxa. During the course of this study, 359 county records were produced, and 18 new taxa were recorded as occurring in the state for the first time. The vascular flora is demonstrably rich, even in comparison to other ecosystematic studies completed within the State. In contrast to other counties and in conformity with a long land and water use history, Jackson County has nearly 20% of the flora comprising alien taxa. As expected and evidenced by the life-form spectra dominated by hemicryptophytes and therophytes, the species are well-adapted to …

Validation Of Coral Temperature Calibrations, Thomas J. Crowley, Terrence M. Quinn, William T. Hyde

Marine Science Faculty Publications

Geochemical analyses of coral skeletons are increasingly used to estimate past sea surface temperatures (SSTs). In this paper we suggest that the standard method of calibrating geochemical time series against a (usually short) local time series requires modification. In order to draw large‐scale inferences about climate from coral proxy data it is also necessary to (1) calibrate against larger fields such as the local gridded data sets and (2) validate results against an independent data set (e.g., early 20th century). This approach has been applied in a pilot study to a coral record from New Caledonia. Despite a high δ18O …

Oviposition By European Corn Borer (Lepidoptera: Crambidae) In Response To Various Transgenic Corn Events, Richard L. Hellmich, L. S. Higgins, John F. Witkowski, J. E. Campbell, L. C. Lewis

Haskell Agricultural Laboratory (Northeast Research and Extension Center)

Oviposition preference by European corn borers, Ostrinia nubilalis (Hübner), for or against transgenic corn would influence amounts of refuge required for resistance management. The objective of this research was to determine if various Bacillus thuringiensis (Bt) corn transgenic events influence O. nubilalis oviposition. All commercially available events (currently 5) were evaluated, plus 1 experimental event. Results from 3 independent studies are reported, including 3 field-cage experiments with vegetative corn, 2 field-cage experiments with reproductive corn, and 2 field experiments with natural O. nubilalis on reproductive corn. In each case, Bt corn hybrids are compared with their near isogenic hybrids by …

Three-Dimensional Reconstructions Of Tadpole Chondrocrania From Histological Sections, Gary P. Radice, Mary Kate Boggiano, Mark Desantis, Peter M. Larson, Joseph Oppong, Matthew T. Smetanick, Todd M. Stevens, James Tripp, Rebecca A. Weber, Michael Kerckhove, Rafael O. De Sá

Biology Faculty Publications

Reconstructing three dimensional structures (3DR) from histological sections has always been difficult but is becoming more accessible with the assistance of digital imaging. We sought to assemble a low cost system using readily available hardware and software to generate 3DR for a study of tadpole chondrocrania. We found that a combination of RGB camera, stereomicroscope, and Apple Macintosh PowerPC computers running NIH Image, Object Image, Rotater. and SURFdriver software provided acceptable reconstructions. These are limited in quality primarily by the distortions arising from histological protocols rather than hardware or software.

Review Of Population Biology Of Grasses, Thomas B. Bragg

Biology Faculty Publications

Population Biology of Grasses provides a wealth of knowledge beyond population biology that ecologists and ecosystem biologists will find relevant to their concerns, particularly those with an interest in grasslands. Though not limited to the Great Plains region, the book would make an excellent addition to the reference shelf of anyone interested in grasses and grassland-related ecosystems, including readers with an interest in land management and preservation. While the papers are written for different levels of readers, all provide information accessible to non-specialists.

Evolutionary Patterns Of Morphometrics, Allozymes And Mitochondrial Dna In Thrashers (Genus Toxostoma), Robert M. Zink, Donna L. Dittmann, John Klicka, Rachelle C. Blackwell-Rago

Ornithology Program (HRC)

We examined patterns of variation in skeletal morphometrics (29 characters), allozymes (34 loci), mitochondrial DNA (mtDNA) restriction sites (n = 74) and fragments (n = 395), and mtDNA sequences (1,739 bp from cytochrome b, ND2, ND6, and the control region) among all species of Toxostoma. The phenetic pattern of variation in skeletal morphometrics generally matched traditional taxonomic groupings (based on plumage patterns) with the exceptions of T. redivivum, which because of its large size clusters outside of its proper evolutionary group (lecontei), and T. occelatum, which did not cluster with T. curvirostre. Skull characters contributed highly to species discrimination, suggesting …

7 | Jericho: The Jewish Cemetery Of The Second Temple Period, Rachel Hachlili, Ann E. Killebrew

IAA Reports—Monograph Series of the Israel Antiquities Authority

This volume describes the excavations that took place during the 1970s, in Hellenistic and Roman-period tombs on the outskirts of the modern city of Jericho, revealing a Jewish cemetery of the Second Temple period. Early Roman-period Jericho was the second largest city in Judea, well known for its date palm groves and especially its balsam. The Hasmoneans erected winter palaces here, as did King Herod. This final report presents descriptions of the tombs and the finds, including pottery, inscriptions, coffins and ossuaries, and provides a wealth of new data on Jewish burial customs during the 1st century BCE to the …

Cleome Hirta Essential Oil As Livestock Tick (Rhipicephalus Appendiculatus) And Maize Weevil (Sitophilus Zeamais) Repellent, M. W. Ndungu, S. C. Chhabra, W. Lwande

All Peer-Reviewed Publications

The repellency of the essential oil of the shrub Cleome hirta and of three identified constituents (phytol, (+)-cedrol, n-octacosane) was evaluated against the livestock tick, Rhipicephalus appendiculatus and the maize weevil, Sitophillus zeamais. In a tick climbing repellency bioassay, the oil exhibited repellency which, at the highest dose, was comparable to that of the commercial arthropod repellent N,N-diethyltoluamide (DEET). In a Y-tube olfactometer bioassay, the oil showed higher or comparable repellency against S. zeamais relative to DEET at all the doses tested. The potential of C. hirta in livestock tick and maize weevil control is discussed. Copyright (C) 1999 Elsevier …

That same knowledge will support advances in healthcare research and education. Home care and remote medicine will increase, reducing the need for high-cost hospitalization. …

Efficient Support For Decision Flows In E-Commerce Applications, Richard Hull, Francois Llirbat, Jianwen Su, Guozhu Dong, Bharat Kumar, Gang Zhou

Kno.e.sis Publications

In the coming era of segment-of-one marketing, decisions about business transactions will be quite intricate, so that customer treatments can be highly individualized, reflecting customer preferences, targeted business objectives, etc. This paper describes a paradigm called “decision flows” for specifying a form of incremental decision-making that can combine a myriad of diverse business factors and be executed in near-realtime. Starting with initial input, a decision flow will iteratively gather and derive additional information until a conclusion is reached. Decision flows can be specified in a rules-based manner that generalizes so-called “business rules” but provides more structure than traditional expert systems. …

Abortion In Cattle, Clell Bagley

Abortion is the premature expulsion of the fetus from the dam and usually occurs because the fetus has died in-utero. If death occurs at 1-2 months of gestation, it is usually termed “early embryonic death.”

Comparative Taphonomy And Paleoecology Of A Glaciomarine Fauna, Carboniferous (Westphalian- Namurian) La Capilla Fm., Argentina, Rex A. Hanger, Mohutsiwa Gabadirwe

Virginia Journal of Science

The Carboniferous La Capilla Fm. of the Calingasta-Uspallata basin of western Argentina contains a low diversity fauna inhabiting a continental shelf under glacial ice fronts advancing from the east. Distal glaciomarine sediments on these ice-influenced shelves of Gondwana are most commonly interpreted as being deposited under quiet, low-energy conditions. Ta­phonomic and paleoecologic analysis of a sample of the fauna reveals the following: low species richness, yet comparable equitability to coeval, tropi­cal faunas; low articulation ratios and high pedicle valve dominance for brachiopods; diverse corrasion modes, about half relatively high categories; one hundred percent fracturing of brachiopod shells, with carinate fracture …

Pfiesteria Piscicida And Dinoflagellates Similar To Pfiesteria, Harold G. Marshall

Virginia Journal of Science

Pfiesteria pisiccida is a microscopic, unicellular organism that is classified as both a mixotrophic and heterotrophic dinoflagellate, which has been associated with both fish deaths and a cause of human illness (Burkholder et al., 1992; Glasgow et al., 1995; Burkholder and Glasgow, 1997). This species possesses a complex life cycle that includes motile forms (e.g. zoospores, gametes, amoebae) and a cyst stage that may remain dormant in the sediment (Burkholder et al., 1995b). Pfiesteria piscicida is known to have toxin and non-toxin producing populations, where cyst transformation into the toxic motile zoospores may be initiated by the presence of certain …

Blissus Occiduus (Hemiptera: Lygaeidae): A Chinch Bug Pest New To Buffalograss Turf, Frederick P. Baxendale, Tiffany Heng-Moss, Terrance P. Riordan

Department of Entomology: Faculty Publications

Blissus occiduus Barber, a relatively small chinch bug characterized by conspicuous wing dimorphism, has emerged as an important insect pest of buffalograss, Buchloe dactylnides (Nuttall) Engelmann. It completes 2 generations a year on buffalograss in Nebraska. Overwintered adults become active as early as mid-March. Depending on the season, 1st-generation nymphs can be present from early May through early August, with 1st-generation adults (up to 60% macropterous forms) appearing in mid to late June. Second generation nymphs can be present from early July through fall, with 2nd-generation adults appearing in late August to early September. These predominately brachypterous (>95%) adults …

Cartilage Regeneration On A Large Articular Surface Facilitated By Stress Shielding, Charles L. Mcdowell, Jennifer S. Wayne, Robert Tuten, Hunter H. Mcguire Jr.

Virginia Journal of Science

An animal model for the study of articular cartilage regeneration in-vivo facilitated by stress-shielding is introduced. The object of the model is to test the hypothesis that some form of cartilaginous tissue will grow upon a large joint surface in vivo with the joint in normal motion. The model utilizes the known capability of immature cells to differentiate. The source of cells is bleeding subchondral bone. In addition, the model provides a mechanically shielded environment in which cell differentiation and maturation can occur. The study showed that a substantial amount of tissue will grow in the animal model only when …

Herbicide Evaluation In Arkansas Rice, 1998, Ron Talbert, Ford Baldwin, David Gealy, Tomilea Dillon, Lance Schmidt, Eric Scherder, Celeste Wheeler, Leopoldo Estorninos Jr., Jeff Rutledge, Rebecca Chavez

Arkansas Agricultural Experiment Station Research Series

Weed control is economically important for production of rice, a major crop in Arkansas. These findings summarize efforts of the team of Arkansas scientists working on weed control strategies for rice during 1998. Various technologies were evaluated in field studies involving the major weed problems and rice production systems used in the state. Results from these studies will add to the arsenal of weed control options for producers. The preliminary results reported here generally warrant further testing for more advanced findings and for the labeling of new technologies and, finally, are the basis for updating safe, effective, and economical recommendations …

Abnormal Electrical Potentials In Lower Limb Muscles After Ankle Sprain Grades I, Ii And Iii, Talal A. Al-Shatti

Rehabilitation Sciences Theses & Dissertations

Fibrillation and positive sharp wave potentials have been found after ankle sprain in muscles around the injured joint. The purpose of this study was to better define and explain the reaction of the muscles around the ankle joint after grades I, II and m ankle sprains. Methods: Fifteen subjects (9 males and 6 females, mean age of 33.2 years) with ankle sprains voluntarily participated in this study. A stress x-ray was done to determine the grade of ankle sprain. Nerve conduction velocity and EMO studies were done three weeks after the injury. None of the patients in this study manifested …

Differentiation Of Mexican Species Of Haematoloechus Looss, 1899 (Digenea: Plagiorchiformes): Molecular And Morphological Evidence, Virginia León-Règagnon, Daniel R. Brooks, Gerardo Perez-Ponce De Leon

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Molecular evidence is interpreted in the light of morphology to examine the validity of several species of Haematoloechus described as Mexican endemics. Internal transcribed spacers 1 and 2 and 28S ribosomal genes were sequenced for 11 isolates. Phylogenetic analysis of separate partitions and combined databases was conducted. Results were analyzed, in the light of morphological evidence. Haematoloechus macrorchis is proposed as a junior synonym of Haematoloechus longiplexus. Haematoloechus pulcher is a sibling species with Haematoloechus complexus in Lerma wetlands. In Mexico, Haematoloechus medioplexus is distributed along the east coast coinciding with the distribution of Rana berlandieri. The sister …

P53 And Pcna Expression In Benign, Atypical And Malignant Meningiomas, R Ahmed, I N. Soomro, S A. Aziz, S H. Hasan

Department of Pathology and Laboratory Medicine

Objective: Alterations: p53 genes are turning out to be the most common genetic alterations in human cancers. Due to long half-life of mutated p53, its detection is possible by immunohistochemistry. Proliferating cell nuclear antigen (PCNA) is expressed by dividing cells, hence has been shown to correlate with prognosis. We have used monoclonal antibodies protein DO-7 (p53) and PC10 (PCNA) to see whether their expression correlates with histological grading in meningethelial tumour.
Material and Methods: a Twenty nine meningiomas (20 benign, 7 atypical and 2 malignant) were selected from the records of our laboratory. p53 and PCNA expression was sought by …
