Subclinical Cytomegalovirus Infection in Neonates: Its Effect on Intellectual and Auditory Functioning.
… nervous system disease (Stem, Booth, Eleck and Fleck, 1969). In addition, thrombocytopenia, chorioretinitis, pneumonia and diarrhea also may be found (Emmanuel and Kenny, 1966 ; Medearis, 1964, and Weller and Hanshaw, 1962). CMV, when associated with this classical array of symptoms, is referred …

Kleiderleben in Münster: anti-ökologische Einstellungen versus Muster der Nachhaltigkeit in einem 'konservativen' Münsteraner Milieu
… Diskurse ein, wo dieser ein blinder Fleck ist, sondern auch in Hinblick auf alltägliche Umgangs - und Nutzungsweisen aus Sicht der TrägerInnen, was in dieser Studie im Fokus des Interesses liegt.

Development of discontinuous Galerkin method for nonlocal linear elasticity
… strain-gradient theory developed by Fleck and Hutchinson within the Toupin-Mindlin framework. The single-field displacement method obtained enables the discretization of the boundary value problem with a conventional continuous interpolation inside each finite element, whereas the …

Structural Integrity of Polymer Matrix Composites Exposed to Fire Conditions
… thermal and mechanical loading. The Budiansky-Fleck micro-buckling analysis technique was used as the failure function of the [0] surface plies. A finite element analysis (FEA) analysis was also performed and showed good agreement with the experimental data.

Mathematical modeling of adhesive layer cracks utilizing integral equations
… A theoretical model based on work done by Fleck, Hutchinson, and Suo (1991) is used to study crack path selection. Complex stress potential functions are employed to develop a symbolic derivation. The method of distributed dislocations is utilized to represent the crack. A series of …

Documentation of grapevine leafroll-associated viruses in wine grape varieties and native grape species in Virginia, and examination of the movement of grapevine leafroll disease to develop management strategies
… virus-2 (GLRaV-2), GLRaV-3, and grapevine fleck virus (GFkV) are widespread in grapes around the world. These viruses can cause significant crop loss and affect wine quality by reducing sugar accumulation and compromising skin color. Mealybugs are vectors of grapevine leafroll-associated …

Variational constitutive updates for strain gradient isotropic plasticity
… 28:845-857, 1991]. As indicated in the paper [Fleck and Hutchinson, jmps, 49:2245-2271, 2001], one parameter is not sufficient to match the experimental data. Therefore a robust and efficient computational framework that can deal with more parameters is still in need. In this thesis, a …
