Associated Metrics,ization. We also discuss the action of symplectic and contact transformations on associated metrics. Some of our discussion is broader, dealing with almost Hermitian and almost contact metric structures. The chapter closes with several examples.

Sasakian and Cosymplectic Manifolds,lso introduce another important structure tensor, ., which will be useful in the study of non-Sasakian contact metric manifolds. As an additional topic, cosymplectic manifolds will be discussed in some detail. We also give several examples and additional commentary.

Curvature Functionals on Spaces of Associated Metrics,ct manifolds. Since these spaces are smaller than the space of Riemannian metrics of the same total volume, one expects for the classical curvature functionals weaker but still interesting critical point conditions. Other functionals that depend on the symplectic and contact structures are also considered.

ns (CA-UTIs) is the duration of catheterization. In chronically catheterized patients, bacteriuria is considered universal and is usually polymicrobial. For these reasons, unnecessary catheter use should be avoided as much as possible, and the duration of catheterization should be minimized. Moreove

The most widely used classifications of UTI are those developed by the Centre for Disease Control and Prevention in USA (CDC) in 1988 and updated

Do Humans Dream of Disappearing Insects?: Fictional Strategies to Convey the Impact of Insect Lossnic . offers a powerful case that empathy is an essential attribute of humanity. However, it is difficult for most of us to experience the same empathy for insects that we feel for other animals. Insects are perceived as invasive, carriers of disease, and destructive of property; they are less “cute
