Nevertheless, it is important to note that measuring PCSA allows a better estimate of muscle fiber specific tension in vivo than ACSA, as changes in pennation angle obscure the underlying
force per unit area within the muscle (Morse et al. 2008).
This rapid deceleration causes a large and fast strain (change in relative length) to occur in the adductor muscles as well as a very high stress (
force per unit area).
They can generate about six times more
force per unit area than mammalian skeletal muscle can, and are also incredibly lightweight; a 2.6 - gram muscle can lift a 3 - kilogram object, which is the equivalent of a mallard duck lifting a car.
Just as our weight puts pressure on the ground beneath our feet, the weight of the atmosphere above us exerts pressure on the planet's surface and everything located on it (recall that pressure is defined as
force per unit surface).
Radiative effects of surface - observed cloud cover anomalies, called «cloud cover radiative forcing (CCRF) anomalies,» are estimated based on a linear relationship to climatological cloud radiative
forcing per unit cloud cover.
«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-.
The range of uncertainty in the radiative forcings can be isolated from the uncertainties in the simulated sulphate loadings by considering the range in the normalised radiative forcing i.e., the radiative
forcing per unit mass of sulphate aerosol (e.g., Nemesure et al., 1995; Pilinis et al., 1995).

As action potentials increase towards around 30 — 40 pulses

For the # 16,430 SEAT it's a diesel's high thermal efficiency, allowing an official 61.4 «combined» mpg and 123g / km (diesel produces more CO2

Sure, the

forces you to eat more than you normally would or if you have to scrape the last 25 % into the garbage.
In the real world, power does not mean that one can order other people around — power means

Therefore the

A band with optical thickess
per unit gas decaying exponentially away from a peak: Assuming the peak is saturated at some level within the atmopshere and there are no other absorbers in the same band of wavelengths above that level, increasing the concentration of that gas will result in at least an instantaneous cooling
forcing of the layer above (not necessarily all of the layer, but the instantaneous
forcing on the layer as a whole will be negative).
Nonetheless, there is a tendency for similar equilibrium climate sensitivity ECS, especially using a Charney ECS defined as equilibrium global time average surface temperature change
per unit tropopause - level
forcing with stratospheric adjustment, for different types of
forcings (CO2, CH4, solar) if the
forcings are not too idiosyncratic.
I never asserted that sensitivity in terms of equilibrium time - average surface temperature change
per unit change in TOA or even tropopause - level
forcing (with or without stratospheric adjustment) would be the same for each type of
forcing for each climatic state and the external
forcings that maintain it (or for that matter, for each of those different of
forcings (TOA vs tropopause, etc.) with everything held constant.
The efficacy of a
forcing is the climate sensitivity (in terms of global average surface temperature change
per unit global average RF) of that
forcing relative to a standard type of
forcing.
For example, if the Earth got cold enough, the encroachment of snow and ice toward low latitudes (where they have more sunlight to reflect
per unit area), depending on the meridional temperature gradient, could become a runaway feedback — any little
forcing that causes some cooling will cause an expansion of snow and ice toward lower latitudes sufficient to cause so much cooling that the process never reaches a new equilibrium — until the snow and ice reach the equator from both sides, at which point there is no more area for snow and ice to expand into.
Thus, for a sufficiently small change in CSD, double that change will result in approximately double the change in intensity at every angle, and thus the same applies to the change in flux
per unit area; thus the radiative
forcing is linearly proportional to changes in CSD for sufficiently small changes.
One can consider net PR+CR as a response to externally - imposed RF (external
forcing) plus feedback «RF», or one can consider PR + CR — feedback «RF» as the response to the externally imposed RF; the later is perhaps more helpful in picturing the time evolution toward equilibrium (and illustrates why the time it takes for an imbalance, equal to: externally imposed RF — climate dependent terms (PR + CR — feedback «RF»), to decay is proportional to both heat capacity and climate sensitivity (defined
per unit externally imposed RF).
(PS we are considering the climate sensitivity to be in terms of changes in global - time average surface temperature

I like the definition of climate sensitivity as «change in surface temperature

So if the system has less energy than average, it would be more efficient at storing energy and the change in enthalpy

Given a

You can substitute your own numbers; if the

per unit warming then you can have a larger internal component before you flip the sign of the heat uptake.
It is described by Here, a1 is a fixed heat capacity, which we approximate as the effective heat capacity
per unit area of a 75 m ocean mixed layer; a3 corresponds to a doubling of atmospheric CO2 levels causing a
forcing of 3.74 W m − 2; and C0 is the pre-industrial concentration of CO2 [30]; a0 and a2 are both able to vary, and control the climate sensitivity, and rate of advection of heat through the thermocline, respectively.
This relationship determines that in hydrostatic equilibrium any work — w ∂ pi / ∂ z performed by the vertical partial pressure gradient
per unit time
per unit atmospheric volume is compensated exactly by the work — wγiρg performed by the
force of gravity that acts on a corresponding molar share γi of the air mass (here w is vertical velocity).

Climate sensitivity (S) is the equilibrium global surface temperature change (ΔTeq) in response to a specified

The radiative
