Having taught at university level in the 1950s and then again in the 1990s, I was appalled by the decline in capability of the average college student over that period.
FCC particles are partially composed of active alumina and zeolite phases that perform the precracking and cracking, respectively.[ 1– 3] As the catalyst ages, the harsh physical and chemical process conditions cause a decline in the overall cracking capability of FCC catalyst particles.
Hypothesis 2 proposed that the decline in the everyday practical capabilities of dementia patients in whom the care level increased across 22 months would be reflected by a greater change in the E-ADL score across 12 months than in dementia patients in whom the care level did not change.
As discussed earlier, the decline in capability of elderly drivers has contributed to the fact that compared to middle aged drivers elderly drivers are more often involved in traffic accidents, killed or seriously injured in accidents which involve other vehicles.
Other recent studies provide evidence to suggest that greater rates of decline in physical capability over time in later life are associated with higher rates of death.
The rates have increased in the sectors of "Agriculture, Forestry and Fishery" (from 0.53 in 2010 to 0.65 in 2013) and "Electricity, Gas and Water Supply" (from 0.20 to 0.45), reflecting the decline in production capabilities or sudden rise in demand.
The perception of U.S. decline in the Middle East is less about its capabilities than about its policy choices and its inability to translate capabilities into outcomes.
The result would be a dramatic decline in Egyptian military capability and in industrial revenues to the armed forces.
Despite these troubling challenges, the U.S. Navy's fleet is undergoing a decline in numbers and capability amid strained defense budgets, and we are losing the confident advantage we had in the 1990s.
