Set in Stone?:

Oocyte vitrification--women's emancipation set in stone.

The techniques of vitrification of oocytes and the subsequent warming process being used today are now producing results far superior to the results that are obtained with slow-freezing techniques, and it would seem that this is the method of female fertility preservation that will be widely used in the near future. The reported success of the use of this method should stimulate a renewed debat...

Stone Algebra Extensions with Bounded Dense Set

Stone algebras have been characterized by Chen and Grätzer in terms of triples (B;D;'), whereD is a distributive lattice with 1; B is a Boolean algebra, and ' is a bounded lattice homomorphism from B into the lattice of …lters of D: If D is bounded, the construction of these characterizing triples is much simpler, since the homomorphism ' can be replaced by one from B into D itself. The triple ...

Set in stone? A perspective on the concrete sustainability challenge

Sustainability challenges and opportunities With more than one-half of the world’s growing population (now ∼ 7 billion) living in cities, a sustainable physical infrastructure is central to improving and maintaining a high quality of life. Concrete is an important component of this infrastructure, with a current annual per capita consumption of about 2.8 tonnes (t) ( Figure 1 ). Concrete powers...

Stone Composition in Patients Who Undergo Renal Stone Surgery: Review of 423 Stone Analyses in Southern Iran

Fibroblast Growth Factor 23 and Vascular Calcification: Is It Set in Stone.

health [5] . The volumetric bone mineral density, estimated glomerular filtration rate (eGFR), albuminuria and levels of calcified atherosclerotic plaque (CAP) in coronary, carotid and aortic vascular beds were correlated [5] . After adjusting for covariates, analyses revealed an expected negative correlation with eGFR. However, the core finding observed by the investigators was the association...
