The DIS diffractive cross section, dσdiffγ*p→XN/dMx, has been measured in the mass range Mx < 15 GeV for γ*p c.m. energies 60 < W < 200 GeV and photon virtualities Q2 = 7 to 140 GeV2. For fixed Q2 and Mx, the diffractive cross section rises rapidly with W, dσdiffγ*p→X N (Mx, W, Q2)/dMx ∝ Wadiff with adiff = 0.507 ± 0.034 (stat) +0.155-0.046 (syst) corresponding to a t-averaged pomeron trajectory of ̄αℙ = 1.127 ± 0.009 (stat) +0.039-0.012 (syst) which is larger than ̄αℙ observed in hadron-hadron scattering. The W dependence of the diffractive cross section is found to be the same as that of the total cross section for scattering of virtual photons on protons. The data are consistent with the assumption that the diffractive structure function FD(3)2 factorizes according to cursive greek chiℙFD(3)2(cursive greek chiℙ, β, Q2) = (cursive greek chi0//cursive greek chiℙ)nFD(2)2(β, Q2). They are also consistent with QCD based models which incorporate factorization breaking. The rise of cursive greek chiℙFD(3)2 with decreasing cursive greek chiℙ and the weak dependence of FD(2)2 on Q2 suggest a substantial contribution from partonic interactions.

Measurement Of High-Q2 Neutral-Current E+P Deep Inelastic Scattering Cross-Sections At Hera, J. Breitweg, S. Chekanov, M. Derrick, D. Krakauer, S. Magill, B. Musgrave, A. Pellegrino, J. Repond, R.

The e+p neutral-current deep inelastic scattering differential cross-sections dσ/dQ2, for Q2 > 400 GeV2, dσ/dx and dσ/dy, for Q2 > 400, 2500 and 10000 GeV2, have been measured with the ZEUS detector at HERA. The data sample of 47.7 pb-1 was collected at a center-of-mass energy of 300 GeV. The cross-section, dσ/dQ2, falls by six orders of magnitude between Q2 = 400 and 40000 GeV2. The predictions of the Standard Model are in very good agreement with the data. Complementing the observations of time-like Z° contributions to fermion-antifermion annihilation, the data provide direct evidence for the presence of Z° exchange in the …

Measurement Of Multiplicity And Momentum Spectra In The Current And Target Regions Of The Breit Frame In Deep Inelastic Scattering At Hera, J. Breitweg, S. Chekanov, M. Derrick, D. Krakauer, S.

Charged particle production in neutral current deep inelastic scattering (DIS) has been studied using the ZEUS detector. The evolution of the mean multiplicities, scaled momenta and transverse momenta in Q2 and cursive Greek chi for 10 < Q2 < 5120 GeV2 and cursive Greek chi > 6 × 10-4 has been investigated in the current and target fragmentation regions of the Breit frame. Distributions in the target region, using HERA data for the first time, are compared to distributions in the current region. Predictions based on MLLA and LPHD are inconsistent with the data.

Health-Promoting Properties Of Common Herbs, Winston J. Craig

Faculty Publications

Herbs have been used as food and for medicinal purposes for centuries. Research interest has focused on various herbs that possess hypolipidemic, antiplatelet, antitumor, or immune-stimulating properties that may be useful adjuncts in helping reduce the risk of cardiovascular disease and cancer. In different herbs, a wide variety of active phytochemicals, including the flavonoids, terpenoids, lignans, sulfides, polyphenolics, carotenoids, coumarins, saponins, plant sterols, curcumins, and phthalides have been identified. Several of these phytochemicals either inhibit nitrosation or the formation of DNA adducts or stimulate the activity of protective enzymes such as the Phase II enzyme glutathione transferase (EC 2.5.1.18). Research …

Plea Bargaining And The Criminal Defendant's Obligation To Plead Guilty, Gerard V. Bradley

Journal Articles

One criticism of plea bargaining holds that: "So long as defendants routinely expect to receive some form of sentencing consideration in exchange for an admission of guilt, the essence of a system of bargain justice is present."

Taken as a criticism ― that "bargain justice" is defective justice and that the "routine" upon which it depends should be significantly reduced, or eliminated ― this view is quite mistaken. On the assumption (which I believe to be true, but for which I do not argue here) that a large majority of the criminally accused are in reality guilty, many ― and …

"Private" Environmental Regulation, Human Rights, And Community, Errol E. Meidinger

Journal Articles

Private organizations have recently established numerous programs aimed at improving the environmental performance of industry. Many of the new programs seek to define and enforce standards for environmental management, and to make it difficult for producers not to participate in them. They claim, explicitly and implicitly, to promote the public interest. They take on functions generally performed by government regulatory programs, and may change or even displace government programs. Private programs thus have the potential to significantly reshape domestic and international policy institutions.

This paper describes three major private environmental regulatory programs applicable to forestry and discusses their implications for …

Nonlinear Constrained Optimizer And Parallel Processing For Golden Block Line Search, Duc T. Nguyen, Wilson H. Tang, Yeou K. Tung, Hakizumwami B. Runesha

Civil & Environmental Engineering Faculty Publications

Generalized exponential penalty functions are constructed for the multiplier methods in solving nonlinear programming problems. The non-smooth extreme constraint Gext is replaced by a single smooth constraint Gs by using the generalized exponential function (base a>1). The well-known K.S. function is found to be a special case of our proposed formulation. Parallel processing for Golden block line search algorithm is then summarized, which can also be integrated into our formulation. Both small and large-scale nonlinear programming problems (up to 2000 variables and 2000 nonlinear constraints) have been solved to validate the proposed algorithms.

Guarding The Gate To The Courthouse: How Trial Judges Are Using Their Evidentiary Screening Role To Remake Tort Causation Rules, Lucinda M. Finley

Journal Articles

The article looks at what trial judges are actually doing in toxic tort cases in the post-Daubert world; it reviews and critiques cases in which judges have in effect adopted a new rule of causation law that requires plaintiffs to rely on epidemiology, and in particular epidemiology that demonostrates an increase in relative risk of 2.0 or greater; the article considers the substantive as well as the normative implications of this legal treatment of epidemiology.

Parental Rights And The Ugly Duckling, Margaret F. Brinig, F. H. Buckley

Journal Articles

Hans Christian Andersen's "The Ugly Duckling" is best remembered for its moral, "To be born in a duck's nest, in a farmyard, is of no consequence to a bird, if it is hatched from a swan's egg." Having read and thought about this story many times, we should like to suggest another, less heart-warming, interpretation. The story of the Ugly Duckling, that most resilient of cygnets, masks the tragedy of children who suffer abuse. Its message, that personal spirit will triumph when a child grows up, misrepresents the experience of many victimized children. If we wait for the child to …

A Submersible Battery-Powered Flow Injection (Fi) Sensor For The Determination Of Nitrate In Estuarine And Coastal Waters, Arj David, T Mccormack, Pj Worsfold

School of Geography, Earth and Environmental Sciences

The design, construction and performance of a remotely deployed submersible flow injection-based nutrient (total oxidized nitrogen) sensor are described. The sensor featured a custom-built microcomputer and a solid-state, flow-through spectrophotometric detector, and the derivatization chemistry was based on in-line coppercadmium reduction of nitrate to nitrite, and diazotization with N1NED and sulphanilamide. The limit of detection was 0.0014 mg l-1 NO3-N and the linear range was 0.0014- 0.77 mg l-1 with a 260 μl sample volume and a 20 mm path length flow cell. Results from submersed deployments in the Tamar estuary and North Sea are also reported.

This report represents a compilation and new analysis of data on the effects and consequences of violent crime among American Indians. The report uses data from a wide variety of sources, including statistical series maintained by the Bureau of Justice Statistics (BJS), the FBI, and the Bureau of the Census. Data are reported from American Indian crime victims on how they were affected by the victimization and about who victimized them. The report also includes the first BJS estimates of the total number of American Indians under the custody or supervision of the justice system.
