Competition, facilitation, and niche differentiation in two foliar pathogens
(
Springer Berlin / Heidelberg
, 2004 , Article)
We studied competition between the obligate biotroph Puccinia triticina (designated here as Puccinia) and the facultative saprophyte Pyrenophora tritici-repentis (designated here as Pyrenophora) in older and younger leaves ...
Man-made impact on the geochemistry of the Nile delta lakes. A study of metals concentrations in sediments
(
Kluwer Academic Publishers
, 2004 , Article)
Forty two sediment samples were collected from four River Nile northern delta lakes (Mariut, Edku, Burullus and Manzalah) to asses the man-made impact on their environment during the last 20 years. Due to the continuous ...
Bordetella pertussis risA, but not risS, is required for maximal expression of Bvg-repressed genes
(
American Society for Microbiology
, 2005 , Article)
Expression of virulence determinants by Bordetella pertussis, the primary etiological agent of whooping cough, is regulated by the BvgAS two-component regulatory system. The role of a second two-component regulatory system, ...
Thermo elastic analysis of functionally graded rotating disks with temperature-dependent material properties: uniform and variable thickness
(
Springer Science+Business Media, B.V.
, 2009 , Article)
A thermo elastic analysis is presented for axisymmetric rotating disks made of functionally graded material (FGM) with variable thickness. Material properties are assumed to be temperature-dependent and graded in the radial ...
Functional Overexpression and Purification of a Codon Optimized Synthetic Glucarpidase (Carboxypeptidase G2) in Escherichia coli
(
Springer US
, 2009 , Article)
Glucarpidase (former name: carboxypeptidase G2, or CPG2) is a bacterial enzyme that is widely used in detoxification of the cytotoxic drug, methotrexate, and in Antibody Directed Enzyme Prodrug Therapy for cancer treatment. ...
Sinc-based computations of eigenvalues of Dirac systems
(
Springer Netherlands
, 2007 , Article)
The celebrated classical sampling theorem is used to compute approximate values of the eigenvalues of Dirac systems with eigenvalue parameter in the boundary conditions. We deal with problems with an eigenparameter in one ...
Empirical likelihood intervals for the population mean and quantiles based on balanced ranked set samples
(
Springer-Verlag
, 2008 , Article)
We consider nonparametric interval estimation for the population mean and quantiles based on a ranked set sample. The asymptotic distributions of the empirical log likelihood ratio statistic for the mean and quantiles are ...
Resident physician and hospital pharmacist familiarity with patient discharge medication costs
(
Springer Netherlands
, 2008 , Article)
Objective Cost-related medication non-adherence is associated with increased health-care resource utilization and poor patient outcomes. Physicians-in-training generally receive little education regarding costs of prescribed ...
