According to SEER, the types of ovarian cancers in women age 20 + are as follows:

In most countries, the SEER is a unitless ratio, as both cooling energy and energy consumed are measured in the same units.

A SEER of 13 is approximately equivalent to an EER of 11, and a COP of 3. 43, which means that 3. 43 units of heat energy are removed from indoors per unit of work energy used to run the air conditioner or heat pump.

The SEER and EER of an air conditioner are limited by the laws of thermodynamics.

Today, it is rare to see systems rated below SEER 9 in the United States because aging, existing units are being replaced with new, higher efficiency units.

The United States now requires that residential systems manufactured after 2005 have a minimum SEER rating of 13, although window units are exempt from this law so their SEERs are still around 10.

For most applications, the minimum or near-minimum SEER units are most cost effective, but the longer the cooling seasons, the higher the electricity costs, and the longer the purchasers will own the systems, the more that incrementally higher SEER units are justified.

Residential split-system AC units of SEER 20 or more are now available, but at substantial cost premiums over the standard SEER 13 units.

The Surveillance, Epidemiology, and End Results ( SEER ) Program of the National Cancer Institute collects and publish data on cancer incidence and survival throughout the United States.

SEER rating more accurately reflects overall system efficiency on a seasonal basis and EER reflects the system ’ s energy efficiency at one specific operating condition.

* Climate Impacts on Heating Seasonal Performance Factor ( HSPF ) and Seasonal Energy Efficiency Ratio ( SEER ) for Air Source Heat Pumps

In cooling mode, a heat pump's operating performance is described in the US as its energy efficiency ratio ( EER ) or seasonal energy efficiency ratio ( SEER ), and both measures have units of BTU /( h · W ) ( 1 BTU /( h · W ) = 0. 293 W / W ).

* Seasonal energy efficiency ratio ( SEER ), used to define the seasonal efficiency of air conditioners and refrigeration equipment ** Not to be confused with the European Seasonal Energy Efficiency Ratio ( ESEER )

The SEER is thus calculated with the same indoor temperature, but over a range of outside temperatures from 65 to 104 degrees F, with a certain specified percentage of time in each of 8 bins each spanning 5 degrees F. There is no allowance for different climates in this rating.

The Seasonal Energy Efficiency Ratio ( SEER ) has the same units of Btu / W · hr, but instead of being evaluated at a single operating condition, it represents the expected overall performance for a typical year's weather in a given location.

To more accurately describe the performance of air conditioning equipment over a typical cooling season a modified version of the EER is used, the Seasonal Energy Efficiency Ratio ( SEER ), or in Europe the ESEER.

The current industry minimum SEER rating is 13 SEER.

The manufacturer's literature should provide both a COP to describe performance in heating mode, and an EER or SEER to describe performance in cooling mode.

In 2010 Frigidaire was awarded the Consumers Digest Best Buy award for their iQ Drive 22 SEER Heat Pump.

In 2011 Frigidaire was again awarded by Consumers Digest the Best Buy award for the iQ Drive 24. 5 Air Conditioner, which remains the highest SEER rating in the heating and cooling industry.

The National Program of Cancer Registries was established by Congress through the Cancer Registries Amendment Act in 1992, and administered by the Centers for Disease Control and Prevention ( CDC ).. NPCR and SEER together collect cancer data for the entire U. S. population.

In 1973, The Surveillance, Epidemiology and End Results ( SEER ) Program of NCI establishes the first national cancer registry program.

The SEER program population-based cancer registries include Arizona Indians, Cherokee Nation, Connecticut, Detroit, Georgia Center for Cancer Statistics ( Atlanta, Great Georgia, and Rural Georgia ), Greater Bay Area Cancer Registry ( San Francisco-Oakland and San Jose-Monterey ), Greater California, Hawaii, Iowa, Kentucky, Los Angeles, Louisiana, New Jersey, New Mexico, Seattle-Puget Sound, and Utah.

* U. S. National Cancer Institute SEER program

The efficiency of air conditioners is often rated by the Seasonal Energy Efficiency Ratio ( SEER ) which is defined by the Air Conditioning, Heating and Refrigeration Institute in its standard ARI 210 / 240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment.

The SEER rating of a unit is the cooling output during a typical cooling-season divided by the total electric energy input during the same period.

The higher the unit's SEER rating the more energy efficient it is.

In the United States, SEER is computed by measuring cooling in British thermal unit ( BTU ) and energy consumed in watt-hours, so the resulting number is measured in units of 0. 29307107.

Accordingly, maturity level ratings by means of the upper portion and lower portion of the Chart, respectively, should be somewhat similar since Skeletal Age assessments are dependent upon Onsets during infancy and upon Completions during adolescence.

It is clear that there are some differences in the ratings, but there is substantial agreement.

Three factors are generally cited that enabled Schröder to win the elections despite poor approval ratings a few months before and a weaker economy: good handling of the 100-year flood, firm opposition to the USA's 2003 invasion of Iraq, and Stoiber's unpopularity in the east, which cost the CDU crucial seats there.

While there are many sources of error with performance ratings, error can be reduced through rater training and through the use of behaviorally-anchored rating scales.

As such, their distortion ( editorial bias ) of news reportage — i. e. what types of news, which items, and how they are reported — is a consequence of the profit motive that requires establishing a stable, profitable business ; therefore, news businesses favoring profit over the public interest succeed, while those favoring reportorial accuracy over profits fail, and are relegated to the margins of their markets ( low sales and ratings ).
