Core - Science. In archaeology, a core is a distinctive artifact that results from the practice of lithic reduction. In this sense, a core is the scarred nucleus resulting from the detachment of one or more lithic flakes from a lump of source material or tool stone, usually by using a hard hammer percussor such as a hammerstone. In astrophysics, the core of a star is its center where nuclear fusion takes place. In astrophysics and geology, a planetary core is the composite material at the centre of ...

In a transformer or inductor, some of the power that would ideally be transferred through the device is lost in the core, resulting in heat. There are various reasons for such losses, the primary ones being: Magnetic core - Hysteresis loss. The larger the area of the hysteresis loop, the more loss per cycle. Hysteresis loss gets worse at higher frequencies. Magnetic core - Eddy current loss. The induction of eddy currents within the core causes a resistive loss. The higher the resistance of the core material the lower the loss. Lamination of the ...

The technique of coring began as an incidental result of attempts to drill into the Earth’s mantle by the Deep Sea Drilling Program. The value to oceanic and other geologic history of obtaining cores over a wide area of sea floors soon became apparent. Core sampling by many scientific and exploratory organizations expanded rapidly. To date hundreds of thousands of core samples have been collected from floors ...

Modern practice is to ensure that cores remain uncontaminated, since they are analysed for trace quantities of chemicals and isotopes. They are sealed in plastic bags after drilling and analysed in clean rooms. The core is carefully extruded from the barrel; often facilities are designed to accommodate the entire length of the core on a horizontal surface. Drilling fluid will be cleaned off before the core is cut into 1-2 meter sections. Various measurements may ...

A core sample is a cylindrical section of a naturally occurring medium consistent enough to hold a layered structure. In most cases cores are obtained by drilling into the medium with a hollow steel tube called a corer. The hole made for the core sample is called a core hole. A variety of corers exist to sample different media under different conditions. More continue to be invented. In the coring process the sample is pushed more or less intact into the tube. Removed from the tube in the laboratory, it is inspected and analyze ...

Many materials can appear in an ice core. Layers can be measured in several ways to identify changes in composition. Small meteorites may be embedded in the ice. Volcanic eruptions leave identifiable ash layers. Dust in the core can be linked to increased desert area or wind speed. Isotopic analysis of the ice in the core can be linked to temperature and global sea level variations. Analysis of the air contained in bubbles in the ice can reveal the palaeocomposition of the atmosphere, in particular CO2 variations. Beryllium 10 concentrations are linked to cosmic ray intensity which can be a p ...

The "core business" of an organization is an idealized construct intended to express that organization's "main" or "essential" activity. The corporate trend in the mid-20th Century of acquiring new enterprises and forming conglomerates enabled corporations to reduce costs of contracting and other transactions, and enable investors to reduce risks by diversification of business holdings. This trend was reversed in the late-20th Century when corporations began to shed "non-core" divisions and activities. The "unbundling" of the corporation is

A core dump is an record of the raw, unstructured contents of one or more regions of working memory at a specific time, generally used to debug a program that has terminated abnormally (crashed). Nowadays, it typically refers to a file containing the memory image of a particular process, or the memory images of parts of the address space of that process, along with other information such as the values of processor registers, but originally it was a printout of the entire contents of working memory. The name comes from core memory and the image of d ...

This article is in need of attention. You can help Wikipedia by editing it into a better article. Please also consider changing this notice to be more specific. In philosophy, a core ontology is a very basic and minimal ontology consisting only of the minimal concepts required to understand the other concepts. It must be based on a core glossary in some human language so humans can comprehend the concepts and distinctions made. Each natural language tends to rely on its own conceptual m ...

Core Shamanism or Neoshamanism is a system of shamanic beliefs and practices from all over the world. Synthesized by Michael Harner, PhD, core shamanism does not hold a fixed belief system, but instead focuses on the practice of trance travel and may on an individual basis integrate indigenous shamanism, the teachings of Carlos Castaneda and other spiritualities. Specific practices include the use of rapid drumming [about 220 beats per minute] to attain the Shamanic State of Consciousness, communication with power animal ...

Shallow cores, or the upper parts of cores in high-accumulation areas, can be dated exactly by counting individual layers, each representing a year. These layers may be visible, related to the nature of the ice; or they may be chemical, related to differential transport in different seasons; or they may be isotopic, reflecting the annual temperature signal (for example, snow from colder periods has more of the heavier isotopes of H and O). Deeper into the core the layers thin out due to ice flow and eventually individual years ...

Strange things are happening on Earth's surface - everybody with a pacemaker drops dead at once within a 10-block radius. The pigeons in London's Trafalgar Square lose their internal navigational ability and start smashing into windscreens and breaking panes of glass. The world soon realises the cause of these anomalies: Earth's core has stopped rotating. Within a year, the Earth will lose its electromagnetic shield ...

Definition and meaning of core:

core (geology) - the innermost layer of the Earth, consisting primarily of pure metals such as iron and nickel. The core is the most dense layer of the Earth, and is divided into the outer core, which is believed to be liquid, and the inner core, which is believed to be solid

Magnetic core - Straight cylindrical rod. Most commonly used in radios especially for tuning an inductor. The rod sits in the middle of the coil and small adjustments of the rod position will fine tune the inductance. Often the rod is threaded to allow adjustment with a screwdriver. In radio circuits, a dob of wax or resin is used once the inductor has been tuned to prevent the core from moving. The presence of the high permeability core increases the inductance but the field must still spread into the air ...

Any natural medium at or under the Earth’s surface that is consistent enough to maintain a solid or semi-solid structure is layered. The layering comes from successive deposition or growth in time of structural or compositional variants of the medium. Most familiar to us are the layers of the Earth’s surface on which the geologic history of the surface is based; for example, the Eocene, Oligocene, Miocene, etc. Each layer in this case contains distinctive fossils generated by the evolution of species. ...

Intel Core Duo consists of two cores based on the Banias/Dothan microarchitecture, a 2 MB L2 cache shared by both cores, and an arbiter bus that controls both L2 cache and FSB access. Floating point performance has been improved through the addition of SSE3 instructions and improvements to SSE and SSE2 implementations, while integer performance decreased slightly due to higher latency cache. Intel Core also includes Vanderpool (VT) virtualization technology and the ability to disable one core to conserve power. EM64T (Intel x86-64 extensions) will not be available in Yonah. Intel Core Solo is a scaled down ve ...
