Butterflies such as the atala hairstreak, Eumaeus atala Poey, and the frosted elfin, Callophrys irus Godart, are restricted to frequently disturbed habitats where their larval host plants occur. Pupae of these butterflies are noted to reside at the base of host plants or in the leaf litter and soil, which may allow them to escape direct mortality by fire, a prominent disturbance in many areas t...

A general model of the equations of generalized thermoelasticity   for an infinite space weakened by a finite linear opening Mode-I crack is solving. The material is   homogeneous and has isotropic properties of elastic half space. The crack is subjected to prescribed temperature and stress distribution. The formulation is applied to generalized thermoelasticity theories, the Lord-Şhulman...

Given a smooth free action of compact connected Lie group $G$ on manifold $M$, we show that the space $G$-invariant Riemannian metrics $M$ whose automorphism is precisely open dense in all metrics, provided dimension "sufficiently large" compared to $G$. As consequence, it follows every can be realized as some manifold; this recovers prior work by Bedford-Dadok and Saerens-Zame under less strin...

A model of fractional-order of thermoelasticity is applied to study a 2D problem of mode-I crack in a fibre-reinforced thermal environment. The crack is under prescribed distributions of heat and pressure. The normal mode analysis is applied to deduce exact formulae for displacements, stresses, and temperature. Variations of field quantities with the axial direction are illustrated graphically....

OBJECTIVE To explore patient factors related to the use of prescribed and non-prescribed drugs for dyspepsia in The Netherlands. DESIGN Patient survey study. SETTING AND SUBJECTS Questionnaires sent to patients who had a prescription for dyspepsia medication from their general practitioner. MAIN OUTCOME MEASURES Patient factors related to the on-demand use of prescribed medication and the...
