Only a handful of teams led by a small concentration of stars are able to truly compete for a championship and they tend to stay constant for several years.

Indeed, the ability of a small clique in political party apparatuses to determine who runs for office, coupled with proportional representation systems that allow for the concentration of power in the hands of a few, has led to tight control of who gets elected.

A high concentration of CCN generally leads to the formation of clouds with a high concentration of small droplets; whereas fewer CCN lead to clouds with few large droplets.

It seemed so obvious that if fairly small changes in development, which adjusted the timing and concentrations of growth and signaling factors, could have led to the evolution of birds from nonavian dinosaurs, we could readjust those changes in development and get a dinosaur from a chick embryo.

While mostly copper, the blade contains small concentrations of lead, arsenic, silver and more than a dozen other chemical elements.

For instance, higher dietary fiber intake increased a capsule's time in the small intestine and led to a slight increase in hydrogen concentration in the colon, compared with the hydrogen decrease seen on a low fiber diet.

The iPhone did get a clean bill of health from Greenpeace in several areas: no cadmium (a carcinogen) or mercury (a toxin known to cause nerve and organ damage) was detected, and lead and chromium (toxic if ingested or inhaled) were detected in a small proportion of samples and at relatively low concentrations.

Well - known techniques that took place in Flint include preflushing water from taps the night before sampling and using small - mouthed bottles, which artificially lowers lead concentrations in samples, as well as failing to identify and test homes known to have sources of lead in their plumbing from lead services lines or older brass components that contain significant amounts of lead.

When the wind slows down, the concentration of small particles of air pollution (aerosols) increase, which help increase haze and leads to solar dimming in the area.

For example, research in Los Angeles is showing that small methane leaks in homes between the gas meter and heaters and stoves could be leading to higher atmospheric methane concentrations there, he said, whereas other cities may have old, leaking gas pipes.

Estimated effects were similar for the concurrent blood lead concentration and the average blood lead concentration in infancy and smaller, but still significant, for peak lead concentrations (Table 3).

The concept behind microlearning is the understanding that human concentration and focus is limited, and that breaking down information into smaller pieces and spacing it out can lead to higher rates of engagement and retention.

We've stood by as the concentration of wealth have made it possible for small groups of extremely wealthy people to wield power far disproportionate to their number, leading to inaction on issues as broad - ranging as climate change to gun policy.

Because the drains out of the various bathtubs involved in the climate — atmospheric concentrations, the heat balance of the surface and oceans, ice sheet accumulations, and thermal expansion of the oceans — are small and slow, the emissions we generate in the next few decades will lead to changes that, on any time scale we can contemplate, are irreversible.

Here is the IPCC on stratospheric cooling: «When the CO2 concentration is increased, the increase in absorbed radiation is quite small and increased emission leads to a cooling at all heights in the stratosphere.»

If a doubling of CO2 centred on values between low to pre-industrial leads to a smaller (relative) temperature response than doubling CO2 centred on the range between pre-industrial and current values — what does that tell us about future climate sensitivity — under ever - rising concentrations?

«The proportionality of warming to cumulative emissions depends in part on a cancellation of the saturation of carbon sinks with increasing cumulative emissions (leading to a larger airborne fraction of cumulative emissions for higher emissions) and the logarithmic dependence of radiative forcing on atmospheric CO2 concentration [leading to a smaller increase in radiative forcing per unit increase in atmospheric CO2 at higher CO2 concentrations; Matthews et al. (2009)-RSB-.

Reading just that people might easily be led to believe that because human carbon dioxide emissions are so small, they won't be noticed against the background noise of natural exchanges, when that is patently untrue with CO2 concentrations stable within a few ppm around 280 ppm for the last few thousand years until mass fossil fuel burning started.

But opponents of increasing the block size note that this will lead to the centralization of the bitcoin network and the concentration of mining capacities in the hands of large miners because it will not be possible to mine larger blocks for small miners.
