Ped

A ped is a soil particle.

There are five major classes of structure seen in soils: platy, prismatic, columnar, granular, and blocky. There are also structureless conditions. Some soils have simple structure, each unit being an entity without component smaller units. Others have compound structure, in which large units are composed of smaller units separated by persistent planes of weakness.

Types of soil structures

Platy

In platy structure, the units are flat and platelike. They are generally oriented horizontally. A special form, lenticular platy structure, is recognized for plates that are thickest in the middle and thin toward the edges. Platy structure is usually found in subsurface soils that have been subject to leaching or compaction by animals or machinery. The plates can be separated with a little effort by prying the horizontal layers with a pen knife. Platy structure tends to impede the downward movement of water and plant roots through the soil.

They are found most frequently in the C, E, Bs and K horizons as well as in sesquioxides (very old soils that are rich in iron and magnesium).

Norsk Data

Norsk Data was a (mini-)computer manufacturer located in Oslo, Norway. Existing from 1967 to 1992, it had its most active period in the years from the early 1970s to the late 1980s. At the company's peak in 1987 it was the second largest company in Norway and employed over 4,500 people.

Throughout its history Norsk Data produced a long string of extremely innovative systems, with a disproportionately large number of world firsts. Some examples of this are the NORD-1, the first minicomputer to have memory paging as a standard option, and the first machine to have floating-point instructions standard, the NORD-5, the world's first 32-bit minicomputer (beating the VAX, often claimed the first, by 6 years)

Historical overview

The origins of Norsk Data go back to the development of digital computers at the Norwegian Defense Research Establishment at Kjeller, Norway, where several early computers had been designed, such as the SAM and the SAM 2, also known as the FLINK.

The success of this program resulted in the founding of A/S Nordata - Norsk Data Elektronikk on August 8, 1967 by Lars Monrad Krohn, Per Bjørge and Rolf Skår. The company became a significant supplier of minicomputers to many research projects, in particular to CERN in Geneva, Switzerland, where they were chosen to produce the computers for many projects, starting with their Nuclear Accelerator Project, Norsk Data's international breakthrough contract. The other market segments Norsk Data succeeded in were process control, Norwegian municipal administration data centers, newspapers, as well as parts of the educational, health, and university sector.
