Not exact matches

Initial estimates from the administration said the program would allow nearly a million New York families with college - age children, or independent adults, to qualify.

A government - commissioned independent review by a panel of scientists known as JASON estimated that the plutonium primaries in the current warheads will last a minimum of a century in storage, however, and, therefore, recommended that no action be taken other than routine maintenance, such as replacing surrounding circuitry and parts as they age — a core function of the Lifetime Extension Program the W76s are currently undergoing.

Cold weather is also a concern for older people, with Age UK estimating that several thousand die every year from the cold, independent of infection, although recent figures suggest this has fallen in 2013/14 due to milder weather.

For studies that reported incidence in each age category, we fitted log - linear model that contained incidence (dependent variable) and consumption (independent variable) with age as a covariate (median age in each age category), and we estimated the relative risk by using an interaction term between age and consumption.

[edit] On the contrary, there are overwhelming evidences from several independent studies that the middle age was quite warm and that the 16 / 17th centuries were quite cold, this would strongly support Moberg reconstruction and therefore the conclusion of above (and my estimates).

In short, the MARGO data for the ocean show very small temperature change from the ice age to today, and thus lead to the low climate sensitivity, but they disagree with some independent estimates showing larger temperature change.

The inconvenient ice / air age adjustment that is necessary in order to align that false historic record with the recent MLO estimates is another aspect of the attempts to reconstruct past atmospheric CO2 content which warrants careful independent scrutiny, along with the dubious statistical manipulations that are carried out in order to produce the MLO estimates of recent CO2 increase.

We study climate sensitivity and feedback processes in three independent ways: (1) by using a three dimensional (3 - D) global climate model for experiments in which solar irradiance So is increased 2 percent or CO2 is doubled, (2) by using the CLIMAP climate boundary conditions to analyze the contributions of different physical processes to the cooling of the last ice age (18K years ago), and (3) by using estimated changes in global temperature and the abundance of atmospheric greenhouse gases to deduce an empirical climate sensitivity for the period 1850 - 1980.

The process of conducting a cost of quality study includes identifying key cost drivers in the quality standards, collecting relevant data — including from providers — and developing a model to calculate estimated program and per child costs for different ages and settings, such as a child care center or a family home.26 These studies can be conducted by a state agency or by an external independent consultant or organization.
