A Preliminary Mass Balance Model Of Primary Productivity And Dissolved Oxygen In The Mississippi River Plume/Inner Gulf Shelf Region, Victor J. Bierman Jr., Scott C. Hinz, William J. Wiseman Jr., Nancy N. Rabalais, R. Eugene Turner Dec 1994

A Preliminary Mass Balance Model Of Primary Productivity And Dissolved Oxygen In The Mississippi River Plume/Inner Gulf Shelf Region, Victor J. Bierman Jr., Scott C. Hinz, William J. Wiseman Jr., Nancy N. Rabalais, R. Eugene Turner

Faculty Publications

A deterministic, mass balance model for phytoplankton, nutrients, and dissolved oxygen was applied to the Mississippi River Plume/Inner Gulf Shelf (MRP/IGS) region. The model was calibrated to a comprehensive set of field data collected during July 1990 at over 200 sampling stations in the northern Gulf of Mexico. The spatial domain of the model is represented by a three-dimensional, 21-segment water-column .grid extending from the Mississippi River Delta west to the Louisiana-Texas border, and from the shoreline seaward to the 30-60 m bathymetric contours. Diagnostic analyses and numerical experiments were conducted with the calibrated model to better understand the environmental …

Comparison Of Continuous Records Of Near-Bottom Dissolved Oxygen From The Hypoxia Zone Along The Louisiana Coast, Nancy N. Rabalais, William J. Wiseman, R. Eugene Turner Dec 1994

Comparison Of Continuous Records Of Near-Bottom Dissolved Oxygen From The Hypoxia Zone Along The Louisiana Coast, Nancy N. Rabalais, William J. Wiseman, R. Eugene Turner

Faculty Publications

Oxygen depletion is a seasonally dominant feature of the lower water column on the highly-stratified, riverine-influenced continental shelf of Louisiana. The areal extent of hypoxia (bottom waters ≤2 mg l−1 dissolved oxygen) in mid-summer may encompass up to 9,500 km2, from the Mississippi River delta to the upper Texas coast, with the spatial configuration of the zone varying interannually. We placed two continuously recording oxygen meters (Endeco 1184) within 1 m of the seabed in 20-m water depth at two locations 77 km apart where we previously documented midsummer bottom water hypoxia. The oxygen meters recorded considerably different oxygen conditions …

Faculty Publications

Energy flows in deep inelastic electron-proton scattering are investigated at a centre-of-mass energy of 269 GeV for the range Q2 ≥ 10 GeV2 using the ZEUS detector. A comparison is made between events with and without a large rapidity gap between the hadronic system and the proton direction. The energy flows, corrected for detector acceptance and resolution, are shown for these two classes of events in both the HERA laboratory frame and the Breit frame. From the differences in the shapes of these energy flows we conclude that QCD radiation is suppressed in the large-rapidity-gap eents compared to the events …

The Nuts & Bolts Of Cooperative Learning In Engineering, Nikos J. Mourtos Nov 1994

The Nuts & Bolts Of Cooperative Learning In Engineering, Nikos J. Mourtos

Faculty Publications

A great number of engineering students work alone. But in industry, teamwork is required most of the time. Incorporating Cooperative Learning (CL) into an engineering program gives students an opportunity to practice problem solving and communication skills in a "simulated" professional environment. The paper briefly discusses the motivation behind using CL in engineering courses. Then, the essential elements to make CL successful in the classroom are examined and examples of how these elements have been incorporated into engineering courses taught by the author are given. Problems that have been encountered along with possible fixes are also mentioned.

Fibrinolytic Responses To Moderate Intensity Exercise: Comparison Of Physically Active And Inactive Men, Linda M. Szymanski, Russell R. Pate Nov 1994

Fibrinolytic Responses To Moderate Intensity Exercise: Comparison Of Physically Active And Inactive Men, Linda M. Szymanski, Russell R. Pate

Faculty Publications

The purposes of this study were to compare fibrinolytic responses to moderate intensity exercise in physically active and inactive men and during morning and evening exercise. Fourteen physically inactive men (mean age, 34.7 ± 4.0 years) and 12 regularly active men (34.8 ± 4.0 years) performed two exercise sessions, morning and evening, at 50% of maximal oxygen consumption. Tissue plasminogen activator (TPA) andplasminogen activator inhibitor-1 (PAI-1) activity were measured before and after exercise. Data were analyzed using a three-way ANOVA with repeated measures. TPA actively increased with exercise in both groups, although the active group demonstrated greater increases than the …

Descriptive Epidemiology Of Physical Activity In Adolescents, Russell R. Pate, Barbara J. Long, Gregory W. Heath Nov 1994

Descriptive Epidemiology Of Physical Activity In Adolescents, Russell R. Pate, Barbara J. Long, Gregory W. Heath

Faculty Publications

This paper reviews the descriptive epidemiology of physical activity in adolescents. Large population-based studies were reviewed, along with smaller studies using objective monitoring of physical activity. Estimates showed that adolescents engage in physical activity of any intensity for a mean of one hour per day. Approximately two thirds of males and one quarter of females participate in moderate to vigorous activity for 20 min 3 or more days per week. Activity levels decline with increasing age across adolescence, and this decrease is more marked in females than in males. Comparison of these data to physical activity guidelines for adolescents suggests …

Characterization Of The Near-Interface Region Of Chemical Vapor Deposited Diamond Films On Silicon By Backscatter Kikuchi Diffraction, Brent L. Adams, K. Kunze, S. Geier, R. Hessmer, M. Schreck, B. Rauschembach, B. Stritzker

Faculty Publications

The lattice orientations near the interface of chemical vapor deposited diamond films on Si(001) have been studied by orientation imaging microscopy. This technique is based on the automated analysis of electron backscatter Kikuchi diffraction patterns. The electron beam has been scanned in discrete steps over the reverse side of the diamond film after having removed the substrate. The obtained data have allowed us to determine the texture and to visualize quantitatively the orientational arrangement of and among individual diamond crystallites in the near-interface region. A comparison with the orientation of the substrate has proved the existence of epitaxially nucleated grains. …

Antitrust And First Amendment Implications Of Professional Real Estate Investors, Gary Myers Oct 1994

Antitrust And First Amendment Implications Of Professional Real Estate Investors, Gary Myers

Faculty Publications

This article begins with a discussion of the development of Noerr-Pennington immunity as it applies to litigation behavior. Parts III and IV describe the litigation in Professional Real Estate Investors and then analyze the effect of this new decision on predatory litigation law. Part V discusses possible ramifications of the case for other areas of federal and state law in which subjective intent is the sole keystone for the imposition of liability on petitioning activity. Because Professional Real Estate Investors interprets the First Amendment to preclude antitrust liability in these cases, other laws that deter bad faith litigation may no …

Who Are The Parents Biotechnological Children?, Larry I. Palmer Oct 1994

Who Are The Parents Biotechnological Children?, Larry I. Palmer

Faculty Publications

We do not underestimate the difficulties of legislating on this subject. In addition to the inevitable confrontation with the ethical and moral issues involved, there is the question of the wisdom and effectiveness of regulating a matter so private, yet of such public interest. Legislative consideration of surrogacy may also provide the opportunity to begin to focus on the overall implications of the new reproductive biotechnology- in vitro fertilization, preservation of sperms and eggs, embryo implantation and the like. The problem is how to enjoy the benefits of the technology-especially for infertile couples-while minimizing the risk of abuse. The problem …

Comparison Of The S Genes And The Biological Properties Of Respiratory And Enteropathogenic Bovine Coronaviruses, X. Zhang, W. Herbst, K. G. Kousoulas, J. Storz

Faculty Publications

The nucleotide sequence of the S gene of the bovine respiratory coronavirus (BRCV) strain G95, which was isolated from nasal swabs of a calf suffering from respiratory disorders, was determined and compared with the S gene of the enteropathogenic bovine coronavirus (BECV) strain LY138. Sequence analysis revealed 98.7% nucleotide and 98.3% deduced amino acid identities between the S genes of BRCV-G95 and BECV-LY138 without any deletions or insertions. Nucleotide substitutions were distributed randomly throughout the gene. Five monoclonal antibodies specific for the S protein distinguished BRCV-G95 from BECV-L9, but failed to differentiate it from BECV-LY138 in Western blots under denatured …

The Effects Of Gender On Career Decision Problems In Young Adults, Jeffry H. Larson, Mark Butler, Stephan Wilson, Nilufer Medora, Scot Allgood Sep 1994

The Effects Of Gender On Career Decision Problems In Young Adults, Jeffry H. Larson, Mark Butler, Stephan Wilson, Nilufer Medora, Scot Allgood

Faculty Publications

The authors investigated gender differences in psychological problems in the career decision-making (CDM) process of young adults. Specifically, problems with decision anxiety, life-goal awareness, luck-fate orientation, authority orientation, and secondary gain motivation were investigated. Methodology involved administering the Career Decision Diagnostics Assessment (CDDA) instrument to 1,006 college students from four universities. Results indicated no gender differences in global levels of problems in CDM. Women reported more problems with life-goal awareness and authority orientation than did men. Men reported more problems with secondary gain motivations than did women. The results are discussed in terms of implications for gender-differentiated career counseling.

Thomas Hobbes's "A Discourse Of Laws", Noel B. Reynolds Sep 1994

Thomas Hobbes's "A Discourse Of Laws", Noel B. Reynolds

Faculty Publications

The recent discovery that an anonymously published 1620 essay was an early writing of Thomas Hobbes invites investigation of his early thinking. Hobbes relied on mostly classical sources to advance a basically conventionalist theory of law and to anticipate twentieth century analyses of the principles of rule of law such as that made famous by F. A. Hayek.

Global Arrest Of Translation During Invertebrate Quiescence, Gretchen E. Hofmann, Steven C. Hand Aug 1994

Global Arrest Of Translation During Invertebrate Quiescence, Gretchen E. Hofmann, Steven C. Hand

Faculty Publications

Comparing the translational capacities of cell-free systems from aerobically developing embryos of the brine shrimp Artemia franciscana vs. quiescent embryos has revealed a global arrest of protein synthesis. Incorporation rates of [3H]leucine by lysates from 4-h anoxic embryos were 8% of those from aerobic (control) embryos, when assayed at the respective pH values measured for each treatment in vivo. Exposure of embryos to 4 h of aerobic acidosis (elevated CO2 in the presence of oxygen) suppressed protein synthesis to 3% of control values. These latter two experimental treatments promote developmental arrest of Artemia embryos and, concomitantly, cause acute declines in …

Providing An Escape For Inner-City Children: Creating A Federal Remedy For Educational Ills Of Poor Urban Schools, Amy J. Schmitz

Faculty Publications

Children in impoverished, urban areas attend dangerous and decrepit schools, where they receive low quality education which fails to prepare them for meaningful participation in the community. Many states, however, provide no legislative or judicial remedy for these children, who desperately need vocational and educational skills to enable them to escape from the deprivation of their urban landscape. Meanwhile, federal officials speak

Justice Defined - It Takes More Than A Single Opinion To Understand How Legal Reasoning And Personal Experience Shape A 24-Year Career, Richard C. Reuben

Faculty Publications

With his retirement in June after participating in more than 800 cases - including his career-identifying 7-2 opinion in Roe v. Wade legalizing abortion - the definition of Harry Blackmun's tenure lies in the seeming contradiction of commitment and flexibility. Along with a steadfast defense of the right to abortion in Roe, 410 U.S. 113 (1973), and successive cases, Blackmun's significance was in the power of his vote. Often overlooked in the public's emphasis on Roe is an appreciation of Blackmun's reflective, methodical, if not occasionally pointed, jurisprudence.

Increased incidence of telephone answering machines and the use of such devices to screen calls pose a potential threat to the representativeness of samples in telephone surveys. Using data from nine statewide surveys, this analysis examines the extent to which answering machines are used to screen calls and the demographic characteristics associated with answering machine use and call screening. Results show that at most two to three percent of households use answering machines to screen calls, and that such screening is more likely to take place in households with higher family incomes, outside rural areas, and which include individuals who …
