Incorporation Of Atmospheric Oxygen Into The Carbonyl Functionality Of The Protochlorophyllide Isocyclic Ring., C. J. Walker, K. E. Mansfield, K. M. Smith, P. A. Castelfranco Jan 1989

Incorporation Of Atmospheric Oxygen Into The Carbonyl Functionality Of The Protochlorophyllide Isocyclic Ring., C. J. Walker, K. E. Mansfield, K. M. Smith, P. A. Castelfranco

Faculty Publications

Detached cucumber (Cucumis sativus L. var. Beit Alpha) cotyledons incubated in darkness with 5-aminolaevulinic acid and either 16O2 air (control) or 18O2 in N2 accumulated protochlorophyllide. This was converted into methyl phaeoporphyrin alpha 5 and analysed by mass spectrometry. The molecular ion of the methyl phaeoporphyrin alpha 5 derived from the 18O2 incubation was 2 mass units greater than that of the control, establishing that the oxo oxygen atom of the isocyclic ring is derived from atmospheric oxygen.

The Biosynthesis Of The Chromophore Of Phycocyanin. Pathway Of Reduction Of Biliverdin To Phycocyanobilin., S. B. Brown, J. A. Holroyd, D. I. Vernon, Y. K. Shim, K. M. Smith Jan 1989

The Biosynthesis Of The Chromophore Of Phycocyanin. Pathway Of Reduction Of Biliverdin To Phycocyanobilin., S. B. Brown, J. A. Holroyd, D. I. Vernon, Y. K. Shim, K. M. Smith

Faculty Publications

The later stages in the pathway of biosynthesis of phycocyanobilin, the chromophore of phycocyanin, were studied by using radiolabelled intermediates. Three possible pathways from biliverdin IX-alpha to phycocyanobilin were considered. 14C-labelled samples of key intermediates in two of the pathways, 3-vinyl-18-ethyl biliverdin IX-alpha and 3-ethyl-18-vinyl biliverdin IX-alpha, were synthesized chemically and were administered to cultures of Cyanidium caldarium that were actively synthesizing photosynthetic pigments in the light. Neither of these two compounds was apparently incorporated into the phycobiliprotein chromophore, suggesting that two of the three pathways were not operative. By elimination, the results imply that the third possible pathway, which …

Coronary Arteriography And Coronary Bypass Survey Among Whites And Other Racial Groups Relative To Hospital-Based Incidence Rates For Coronary Artery Disease: Findings From Nhds, E. Ford, R. Cooper, A. Castaner, B. Simmons, M. Mar Jan 1989

Coronary Arteriography And Coronary Bypass Survey Among Whites And Other Racial Groups Relative To Hospital-Based Incidence Rates For Coronary Artery Disease: Findings From Nhds, E. Ford, R. Cooper, A. Castaner, B. Simmons, M. Mar

Faculty Publications

To assess racial differences in health care utilization for coronary artery disease (CAD) the data of the National Hospital Discharge Survey (NHDS) from 1979-84 were examined. Discharge rates for acute myocardial infarction (AMI) were utilized as a measure of hospital-based incidence and relative need for the designated cardiac procedures. Although 35-74 year old Black men had discharge rates of AMI that were 77 per cent of those observed for White men, they underwent coronary arteriography half as often and were only a third as likely to have coronary artery bypass graft (CABG) surgery. Black women in this age range were …

The Fourier Transform In White Noise Calculus, Hui Hsiung Kuo Jan 1989

The Fourier Transform In White Noise Calculus, Hui Hsiung Kuo

Faculty Publications

Let S* be the space of termpered distributions with standard Gaussian measure μ. Let (S) ⊂ L2(μ) ⊂ (S)* be a Gel'fand triple over the white noise space (S*, μ). The S-transform (Sφ{symbol})(ζ) = ∫S* φ{symbol}(x + ζ) dμ(x), ζ ∈ S, on L2(μ) extends to a U-functional U[φ{symbol}](ζ) = «exp(·, ζ), φ{symbol} a ̊ exp( -∥ζ∥2 2), ζ ∈ S, on (S)*. Let D consist of φ{symbol} in (S)* such that U[φ{symbol}](-iζ1T) exp[-2-1 ∫Tζ(t)2 dt], ζ ∈ S, is a U-functional. The Fourier transform of φ{symbol} in D is defined as the generalized Brownian functional φ{symbol}̌ in (S)* such …

The Regular Matroids With No 5-Wheel Minor, James G. Oxley Jan 1989

The Regular Matroids With No 5-Wheel Minor, James G. Oxley

Faculty Publications

For r in {3, 4}, the class of binary matroids with no minor isomorphic to M(Wr), the rank-r wheel, has an easily described structure. This paper determines all graphs with no W5-minor and uses this to show that the class of regular matroids with no M(W5)-minor also has a relatively simple structure. © 1989.

A Characterization Of Certain Excluded-Minor Classes Of Matroids, James G. Oxley Jan 1989

A Characterization Of Certain Excluded-Minor Classes Of Matroids, James G. Oxley

Faculty Publications

A result of Walton and the author establishes that every 3-connected matroid of rank and corank at least three has one of five six-element rank-3 self-dual matroids as a minor. This paper characterizes two classes of matroids that arise when one excludes as minors three of these five matroids. One of these results extends the author's characterization of the ternary matroids with no M(K4)-minor, while the other extends Tutte's excluded-minor characterization of binary matroids. © 1989, Academic Press Limited.

Regularization, Pseudofunction, And Hadamard Finite Part, R. Estrada, R. P. Kanwal Jan 1989

Regularization, Pseudofunction, And Hadamard Finite Part, R. Estrada, R. P. Kanwal

Faculty Publications

First, we discuss and correlate the various types of regularizations available in the literature for the singular function H(x) xk, where k is an integer and H(x) is the Heaviside function. Then we present the corresponding regularization for the function r-k, where r is the radial distance in Rn. Thereafter, we express the recently discovered distributional derivatives of this function in terms of pseudofunctional language commonly used in the Coulomb, gravitational, and interparticle potentials where the function 1 r plays a fundamental role. © 1989.

Effect Of Feeding Gossypol In Cottonseed Meal On Growth, Semen Quality, And Spermatogenesis Of Yearling Holstein Bulls, D. A. Jimenez, J. E. Chandler, R. W. Adkinson, W. A. Nipper, A. Baham, A. M. Saxton Jan 1989

Effect Of Feeding Gossypol In Cottonseed Meal On Growth, Semen Quality, And Spermatogenesis Of Yearling Holstein Bulls, D. A. Jimenez, J. E. Chandler, R. W. Adkinson, W. A. Nipper, A. Baham, A. M. Saxton

Faculty Publications

Yearling Holstein bulls were fed a corn silage ration supplemented with either cottonseed meal with gossypol or soybean meal in two trials to evaluate the effect of feeding gossypol on reproductive characteristics. In Trial 1, roughage to concentrate ratio was 88:12 and was fed for 60 d. In Trial 2, roughage to concentrate ratio was 50:50 and was fed for 42 d. Cottonseed meal concentrate had 3.03 g total gossypol/kg DM. Cottonseed meal concentrate was fed to provide 6 and 30 mg total gossypol/kg BW per d in Trials 1 and 2. Ejaculates were collected twice weekly via artificial vagina …

Comparison Of Ascorbic Acid Content Of Super‐Market Versus Roadside Stand Produce, R. J. Bushway, P. R. Helper, J. King, B. Perkins, M. Krishnan Jan 1989

Comparison Of Ascorbic Acid Content Of Super‐Market Versus Roadside Stand Produce, R. J. Bushway, P. R. Helper, J. King, B. Perkins, M. Krishnan

Faculty Publications

Seven vegetables and one fruit from two roadside stands and two major local supermarkets were analyzed for their ascorbic acid content. Produce was sampled during a nine week period from late July through September of 1987. Significant differences at the 0.05 level for ascorbic acid were observed between supermarket and roadside stand produce for potato, cauliflower, cabbage and tomato while no significant differences were found between cantaloupe, broccoli, green peppers and spinach from either market. Cabbage was the only supermarket item that was significantly higher in ascorbic acid concentration. Very little dehydroascorbic acid was shown to be present in these …

Am I My Borrower's Keeper?, Kerry L. Macintosh Jan 1989

Am I My Borrower's Keeper?, Kerry L. Macintosh

Faculty Publications

Suppose a lender is asked to make a substantial loan to a prospective borrower. The lender possesses information indicating that the borrower will use the loan proceeds to finance an activity that, although legitimate on its face, is conducted in violation of regulatory provisions. Nevertheless, the lender makes the loan because it promises to be profitable. Later the borrower defaults, and the lender goes to court to enforce the debt and realize on its security interest in the borrower's property. There, the borrower raises the regulatory violations as a defense. Imagine the lender's consternation, and probable response: "What business is …

The Renewed Concern Over Soil Erosion: The Current Federal Programs And Proposals, Linda A. Malone Jan 1989

The Renewed Concern Over Soil Erosion: The Current Federal Programs And Proposals, Linda A. Malone

Faculty Publications

Because soil erosion affects the quantity and quality of farmland, it is a matter of great concern for both the government and the farm industry. Whereas in the past concern was over the potential damage to productivity, concern is now being voiced over off-site damage and water pollution. There are numerous federal programs set up to fight soil erosion, but they are all voluntary, thereby making it difficult for the government to target funds. The author reviews the seriousness of the problem, looks at the numerous government programs, and then analyzes the Food Security Act of 1985—the first act to …
