Changes in levels of the stress-sensitive hormone cortisol from morning to evening are referred to as diurnal cortisol slopes. Flatter diurnal cortisol slopes have been proposed as a mediator between chronic psychosocial stress and poor mental and physical health outcomes in past theory and research. Surprisingly, neither a systematic nor a meta-analytic review of associations between diurnal c...

A slope p q is called a characterizing slope for a given knot K0 in S if whenever the p q –surgery on a knot K in S is homeomorphic to the p q –surgery on K0 via an orientation preserving homeomorphism, then K D K0 . In this paper we try to find characterizing slopes for torus knots Tr;s . We show that any slope p q which is larger than the number 30.r 1/.s 1/=67 is a characterizing slope for T...

The Keystone Symposium on Stem Cell Differentiation and Dedifferentiation attracted nearly 500 participants affiliated with academia, the biotechnology industry, scientific publishing and clinical practice. This broad group examined current advances in stem-cell biology, with a particular focus on induced pluripotent stem cells, and discussed both their potential and limitations in therapeutic ...

Abstract Coastal fresh groundwater management is a challenging research topic due to the relevance of these resources and huge suffered risks global change overpopulation. The geometrical features coastal aquifers play control role in saltwater intrusion (SWI). Seawater level rise reduction aquifer storage are promoting SWI. All key factors considered with two different numerical approaches def...

We studied tree height in stands of high-Andean Polylepis forests in two cordilleras near Cuzco (Peru) with respect to variations in human impact and climatic conditions, and compared air and soil temperatures between qualitatively defined dry and humid slopes. We studied 46 forest plots of 100 m(2) of five Polylepis species at 3560-4680 m. We measured diameter at breast height (dbh) and tree h...

What do infants learn when they learn to sit upright? We tested behavioral flexibility in learning to sit-the ability to adapt posture to changes in the environment-in 6- to 9-month-old infants sitting on forward and backward slopes. Infants began with slant at 0°; then slant increased in 2° increments until infants lost balance. Infants kept balance on impressively steep slopes, especially in ...
