The massive use of charcoal on an industrial scale in Early Modern Europe was a new type of consumption of western forests ; even in Stuart England, the relatively primitive production of charcoal has already reached an impressive level.

To structure the study of ecology into a conceptually manageable framework, the biological world is organized into a nested hierarchy, ranging in scale from genes, to cells, to tissues, to organs, to organisms, to species, and up to the level of the biosphere.

Another approach that is gaining favor is to scale EVM implementation according to the project at hand and skill level of the project team.

If the firm is a perfect competitor in all input markets, and thus the per-unit prices of all its inputs are unaffected by how much of the inputs the firm purchases, then it can be shown that at a particular level of output, the firm has economies of scale if and only if it has increasing returns to scale, has diseconomies of scale if and only if it has decreasing returns to scale, and has neither economies nor diseconomies of scale if it has constant returns to scale.

The goal is to match or surpass the difficulty level, also on the adjective scale, of the test.

The locks were on a large scale, most having a change of level of.

After a much-disputed truce on 3 January 1928, the Italian policy in Libya reached the level of full scale war, including deportation and concentration of the people of the Jebel Akhdar to deny the rebels the support of the local population.

This means that a driver can be ordered " by an authorised person ... upon production of evidence of his authorisation, require him to stop the running of the engine of that vehicle " and a " person who fails to comply ... shall be guilty of an offence and be liable on summary conviction to a fine not exceeding level 3 on the standard scale ".

An I – O psychologist would typically use information from the job analysis to determine a job's performance dimensions, and then construct a rating scale to describe each level of performance for the job.

The time scale involved at each level of memory processing remains under investigation.

This catalogue was the first on such a scale and with such a level of scholarship behind it ; it has since undergone revisions.

( e. g. LIDAR mapping ) but in fact it is not mapping because a map is created through some cartographic works ( i. e. determining the scale / level of detail and content of geographic or cartographic database, entry criteria and symbol specification for geospatial objects, generalization, layout design etc .).

In addition to describing the motion of atomic level phenomena, quantum mechanics is useful in understanding some large scale phenomenon such as superfluidity, superconductivity, and biological systems, including the function of smell receptors and the structures of proteins.

Socialism cannot exist without a change in consciousness resulting in a new fraternal attitude toward humanity, both at an individual level, within the societies where socialism is being built or has been built, and on a world scale, with regard to all peoples suffering from imperialist oppression.

The level of national mobilization of resources on all sides of the conflict, the battlespace being contested, the scale of the armies, navies, and air forces raised through conscription, the active targeting of civilians ( and civilian property ), the general disregard for collateral damage, and the unrestricted aims of the belligerents marked total war on an unprecedented and unsurpassed, multicontinental scale.

Some dishwashers can reduce this etching effect by automatically dispensing the correct amount of detergent throughout the wash cycle based on the level of water hardness programmed.

Originally, the golf course was watered from another deep well within the Park boundary at the southeast corner, but that water had such a high level of hardness that it was abandoned in 1985 and the drinking water is now also used on the golf course.

Until the late 19th century, the different varieties of Cheshire cheeses were aged to a sufficient level of hardness to withstand the rigours of transport ( by horse and cart, and later by boat ) to London for sale.

In such applications it is important to balance the hardness of the DLP in and ; depending on the security level values of between 6 and 12 are useful.

* The Computational Diffie-Hellman assumption, indicating a certain level of hardness of a mathematical problem

* HRE, a level of the hardness of metallic materials on the Rockwell scale

Some investigators have found a parallelism between remissions and return of the sympathetic reactivity of the hypothalamus to the normal level as indicated by the Mecholyl test and, conversely, between clinical impairment and increasing deviation of this test from the norm.

Set within the Soviet Union, these two centers were used to field test aircraft and armoured vehicles up to the battalion level, as well as housing aerial and armoured warfare schools through which officers were rotated.

This was a dual subjective and objective test, and one deliberately pitched at a higher level.

While rooted in rather different theories, these two traditions have been characterised by a constant reference to experimental research to test hypotheses, both at clinical and basic level.

Measuring the level of thyroid-stimulating hormone ( TSH ), produced by the pituitary gland ( which in turn is also regulated by the hypothalamus's TSH Releasing Hormone ) in the blood is typically the initial test for suspected hyperthyroidism.

On waking, they would test their blood glucose level periodically until lunch.

Some parents also object to the use of standardized tests ( all students take the same test under the same conditions ) because they think it unfair for schools to require the same level of work or to use the achievement tests for impoverished or disadvantaged students as they do for more advantaged students.

At the state level, exit examinations have proliferated, and now more than half of US high school students will be required to pass a high-stakes test to get a normal high school diploma.

The certificate was earned by taking and passing a written test, which had been designed to determine whether a student was performing at about the tenth grade level.

The sled was then accelerated according to the experiment's design requirements for data collection along a length of isolated, precisely level and straight test track.

Insertion loss is defined as a ratio of the signal level in a test configuration without the filter installed (| V < sub > 1 </ sub >|) to the signal level with the filter installed (| V < sub > 2 </ sub >|).

Net gain is measured by applying a test signal at an appropriate power level at the input port of a circuit and measuring the power delivered at the output port.

The test signal must be chosen so that its power level is within the usual operating range of the circuit being tested.

Attenuators are commonly used in fiber optic communications, either to test power level margins by temporarily adding a calibrated amount of signal loss, or installed permanently to properly match transmitter and receiver levels.

The ratio is usually determined by applying a standard test tone at zero transmission level point ( or applying adjusted test tone power at any other point ) and measuring the gain or loss to the location of interest.

In telecommunication, a standard test signal is a single-frequency signal with standardized level used for testing the peak power transmission capability and for measuring the total harmonic distortion of circuits or parts of an electric circuit.

In telecommunication, a standard test tone is a single-frequency signal with a standardized level generally used for level alignment of single links and of links in tandem.

# subtracting the power level obtained at the output of the fiber under test from the power level obtained at the output of the reference fiber, to get the transmission loss of the fiber under test.
