And a response is 50 percent shrinkage.

One is hierarchical pores, and the other is a macro molecular nanoscale porosity in the material.

Aquifer means a subsurface layer or layers of geological strata of sufficient porosity and permeability to allow either a flow of or the withdrawal of usable quantities of groundwater.

Because of the porosity of the borders and the historically fluid nature of the conflict in the subregion, we will feel safe and secure only in a conflict free region.

Aquifer means a subsurface layer or layers of rock or other geological strata of sufficient porosity and permeability to allow either a significant flow of groundwater or the abstraction of significant quantities of groundwater.

In one delegation s view, the head of the Department should be consulted on any reform of the Department, and there should be no shrinkage or elimination of programmes in a Department that enjoyed a vast consensus within the Organization.

The difficulties include the porosity of borders, the lack of material and financial support and the fact that some officials do not have the genuine political will to achieve integration and unification, all of which undermine the situation with respect to security, political, administrative, economic, social and humanitarian matters.

The development challenge no longer solely consists in bringing agricultural water to deprived areas. As the dramatic shrinkage of the Aral Sea, Lake Chad, and the Dead Sea illustrate, it now requires preserving scarce natural resources and ensuring their equitable distribution among conflicting needs.

As many as 400,000 people were involved in the functioning of the test site when it was fully operational. Analysis of the effects of the Semipalatinsk testing ground must reflect the overall context of the dissolution of the Soviet Union and the massive shrinkage of the economy of the Semipalatinsk region.

Despite the tremendous potential and enormous resources available in Africa, and despite the fact that most African countries carry out appropriate economic policies, the African continent is still suffering from serious political, economic and social crises which have led to the marginalization of our continent and the shrinkage of its role in the international arena.

The good news from Cushing's disease is that hippocampal shrinkage and memory impairment is at least partially reversible over several years after correction of the excess cortisol. This encourages the belief that structural changes in the brain that are associated with major depression can be prevented or even reversed with the right medications and other treatments.

Indeed, in key respects depression is comparable to Cushing's disease, a disorder cause by excessive production of cortisol. The elevated cortisol in Cushing's patients is higher than that found in major depression, but the psychiatric and somatic features of Cushing's disease are strikingly similar melancholia, depression, abdominal obesity, bone mineral loss, and increased risk for cardiovascular disease, along with shrinkage of the hippocampus and memory impairment.

Rapid demographic decline has been brought to a halt since the turn of the century (a time when coffins outnumbered cribs by seven to four), as generous government subsidies for a third child have boosted the fertility rate from its 1999 low of 1.16 children per woman to 1.58 in 2010. That is still far below the replacement rate of 2.1, but higher fertility, together with successful measures to reduce male mortality, has slowed the pace of population shrinkage.
