The Pheiffer core is an analytical technique used in geology to extract a continuous cylinder of rock or sediment sample from the subsurface. It involves drilling a hollow tube into the Earth and retrieving a cylindrical section of material. This core sample can then be analyzed to understand the composition, structure, and history of the rocks or sediments.

How hot does the core of a nuclear reactor get?
This depends very much on the type of reactor. PWR's operate at a high pressure in the primary circuit to prevent boiling, and the outlet water temperature is about 315 degC. In BWR's in contrast, boiling is allowed and the outlet temperature is about 285 degC. Gas cooled reactors can operate at much higher temperatures. In the AGR for example (CO2 cooled, graphite moderated) the gas outlet temperature is designed to be about 540 degC, which allows steam to be produced at conditions the same as in a modern coal fired station, in fact at the last two built the steam turbines were exactly the same as installed in coal fired stations at that time. At these temperatures all steel components in the reactor have to be austenitic, as CO2 oxidises normal steel, and re-entrant gas flow has to be arranged to keep the graphite moderator cool, the gas inlet being at about 300degC. Designs exist for helium cooled gas reactors which could operate even hotter and drive a gas turbine directly, without a steam circuit. These may or may not be commercially exploited.
Are the inner and outer core of earth the same?
No. The inner and outer core are both composed primarily of iron and nickel, but the outer core is liquid and surrounds the inner core. The inner core is the innermost layer of Earth and is kept solid by the enormous pressure.
What is the core divided into?
The Earth's core is divided into two parts: the inner core and the outer core. The inner core is solid iron and nickel, while the outer core is liquid iron and nickel.
What are the two parts of the inner core?
the solid inner core and the liquid outer core
What is thicker inner or outer core?
The outer core is thicker than the inner core. The outer core is about 2,260 kilometers thick, while the inner core is approximately 1,220 kilometers thick.
What has the author Herman Phleger written?
Herman Phleger has written: 'Observations on the U.S. District Court for the Northern District of California, 1900-1940' -- subject(s): Accessible book
Who is doug Johnson married to?
He's married to Kelly Phleger since 1999.
What is the definition of the term core competencies?
The definition of the term "core competencies" is a factor relevant to the way the company or it's employees operate. You can learn more about core competency at the Wikipedia.
What is the definition of a core in electrical equipment?
A core in the electrical trade usually refers to the iron laminations that coils of wire are wrapped around. The core directs the magnetic field, that the coils of wire produce when energized, into a working force. This could be the iron core of a relay or a transformer core that is the centre and principle reason that a transformer can operate.
How do information systems promote synergies and core competencies?
Effective information systems help businesses operate smoothly. They encourage interdepartmental communication, which promotes synergy and the ability to excel in core competencies.
What type of processor housing contains two processors that operate at the same frequency but independently of each other?
dual-core processing
Is the banking system in India whether mixed or branch banking?
Most banks in India offer branch free banking or core banking. If you have an account with the bank you can operate it in any of the bank's branches. This may attract charges as applicable but you can operate it anywhere. There are also some smaller banks that offer only branch specific banking. you will not be able to operate those accounts anywhere else. Almost all banks have migrated or are migrating to core banking.
Why do corporations operate as the core of the US economy?
The US has a capitalistic economy that is based on business innovation and competition. Corporations are the ones that drive a capitalist economy.not helpful
Is it possible to use optic fiber as a core in the transformer?
No. Transformers operate on the principle of conversion of electric current to and from magnetism. Optic fiber is not ferromagnetic, nor is it conductive.
What is type of current that transformers require to operate?
As a transformer requires an alternating magnetic flux within its core, then the current flowing in its primary winding must be alternating.
What is 1 GHz Dual Core processor?
It means that there are two cores on one chip. It is sort of like gluing two single core processors together if that helps to visualize it. It is good for multitasking because each program can use one core and some can use both at once. Both Cores operate at 1 GHz.
What is a chip with four cores each able to operate independently of the other that reads and executes CPU instructions?
A chip with four cores that can operate independently is known as a quad-core processor. Each core can read and execute CPU instructions simultaneously, allowing for improved multitasking and enhanced performance in parallel processing tasks. This architecture is designed to increase computational efficiency by distributing workloads across multiple cores, enabling smoother operation for demanding applications. Quad-core processors are commonly found in modern computers and smartphones.
