This technique was used to produce color prints into the 1930s before the color-film was developed: Three identical black & white photographic takes of an object were made on Ilford Hypersensitive Panchromatic film with the corresponding filters ( blue, green, red ) The developed negatives were enlarged and transposed on bromide-silver photographic paper.

It was nothing more than a tiny distant rain squall, a dull gray sheet which reached from a layer of clouds to the earth.

The results of present observations of the thermal radio emission of the moon are consistent with the very low thermal conductivity of the surface layer which was derived from the variation in the infrared emission during eclipses ( e.g., Garstung, 1958 ).

The most investigated example is represented by thin multicrystalline silicon films, where such as the unoriented molecule. An initial amorphous layer was observed in many studies.

Brown was studying orchids under microscope when he observed an opaque area, which he called the areola or nucleus, in the cells of the flower's outer layer.

While substantial water was detected spectroscopically, it was not as much as predicted beforehand, meaning that either the water layer thought to exist below the clouds was thinner than predicted, or that the cometary fragments did not penetrate deeply enough.

Over time their ethnic origin was forgotten, and they formed the bottom layer of Korean society.

Along with the three or four estates in various European countries, another outcast layer existed below the bottom layer of the hierarchical society, a layer that had no rights and was there to serve the upper layers.

This layer was called serfs.

The Atari OS only offered low-level disk-access, so an extra layer called DOS was booted off a floppy that offered higher level functions such as filesystems.

By 1975, the upper water layer was saltier than the lower layer.

When the upper layer cooled so its density was greater than the lower layer, the waters mixed ( 1978 – 79 ).

The primary motivation for replacing RARP with BOOTP was that RARP was a data link layer protocol.

The substory was either managed and park-like, with understory less than 0. 5 metres in height, or consisted of what he called " Cocos Bon-Dieu " –&# 32 ; an intermediate story of juvenile trees and a luxuriant ground layer of self-sown seedlings –&# 32 ; causing those areas to be relatively impenetrable.

Thus, before the Aswan High Dam was completed in 1971, the White Nile watered the Egyptian stretch of the river throughout the year, whereas the Blue Nile, carrying seasonal rain from Ethiopia, caused the Nile to overflow its banks and deposit a layer of fertile mud over adjacent fields.

To alleviate these problems, bridging was created to communicate at the data link layer while isolating the physical layer.

In December 1960, he suggested the existence of a shell of visible dust particles around the earth some 600 to in space, beyond which there was a layer of smaller particles, a micrometre or less in diameter, extending 2, 000 to.

The task was a demanding one: the river was fast-flowing, up to deep, and had a bed formed of a deep layer of gravel which made the construction of piers on the river bed impossible, and so the bridge had to have a central span of.

This may be due to poor-quality CD recorder drives, low-quality discs, or incorrect storage, as the information-bearing dye layer of most CD-recordable discs is at least slightly sensitive to UV light and will be slowly bleached out if exposed to any amount of it.

Commoly this is used for making a top layer of bleached fiber to go over an unbleached layer.

The metallic hydrogen layer makes up the bulk of each planet, and is described as " metallic " because the great pressure turns hydrogen into an electrical conductor.

Service definitions abstractly described the functionality provided to an ( N )- layer by an ( N-1 ) layer, where N was one of the seven layers of protocols operating in the local host.

In the less common depletion mode MOSFET, described further later on, the channel consists of carriers in a surface impurity layer of opposite type to the substrate, and conductivity is decreased by application of a field that depletes carriers from this surface layer.

In contrast to the model based on functional morphology described earlier, in the Epitheliozoa concept the ventral and dorsal cell layers of the Placozoa are homologs of endoderm and ectoderm, the two basic embryonic cell layers of the eumetazoans — the digestive gastrodermis in the Cnidaria or the gut epithelium in the bilaterally symmetrical Bilateria may have developed from endoderm, whereas ectoderm is, among other things, the precursor to the external skin layer ( epidermis ).

As described, the animal had only a single layer of tissue.

This means that sedimentary facies can change either parallel or perpendicular to an imaginary layer of rock with a fixed age, a phenomenon described by Walther's Law.

The main output pathway ( perforant path, first described by Ramon y Cajal ) of EC axons comes from the large stellate pyramidal cells in layer II that " perforate " the subiculum and project densely to the granule cells in the dentate gyrus, apical dendrites of CA3 get a less dense projection, and the apical dendrites of CA1 get a sparse projection.

This pollution layer was observed during the Indian Ocean Experiment ( INDOEX ) intensive field observation in 1999 and described in the UNEP impact assessment study published 2002.

According to the nineteenth-century account, the drill or " pod auger " passed through a spruce platform at, a head space, of what was described as " metal in pieces ", of oak, another of metal, of oak, another spruce layer, and finally into clay for without striking anything else.

The problem with the simple quantum well diode described above is that the thin layer is simply too small to effectively confine the light.

The work of packetizing and de-packetizing data and status-message traffic is handled by the transaction layer of the PCIe port ( described later ).

Depending on whether the PPVPN ( Provider Provisioned VPN ) runs in layer 2 or layer 3, the building blocks described below may be L2 only, L3 only, or combine them both.

In some networks, such as IEEE 802 local area networks, the data link layer is described in more detail with media access control ( MAC ) and logical link control ( LLC ) sublayers ; this means that the IEEE 802. 2 LLC protocol can be used with all of the IEEE 802 MAC layers, such as Ethernet, token ring, IEEE 802. 11, etc., as well as with some non-802 MAC layers such as FDDI.

He knew Pemex had drilled exploratory wells in the region in 1951, one bored into what was described as a thick layer of andesite about 1. 3 km ( 4, 200 ft ) down.

The depleted uranium alloy of the M1 has been described as " arranged in a type of armour matrix " and a single module as a " stainless-steel shell surrounding a layer ( probably an inch or two thick ) of depleted uranium, woven into a wire-mesh blanket ".

IS-95 is widely described as a three-layer stack, where L1 corresponds to the physical ( PHY ) layer, L2 refers to the Media Access Control ( MAC ) and Link-Access Control ( LAC ) sublayers, and L3 to the call-processing state machine.

In the ideology of Bolsheviks, intelligentsia is not a real class ; its status is described by the Russian word " prosloyka ", which is normally translated as " stratum ," but in this context has a negative connotation, meaning " liner " or " separating layer ".

He also described the membranous layer of subcutaneous tissue of the perineum, which came to be known as Colles ' fascia.

In October, 2010, Mann wrote an op ed in the Washington Post in which he described several past, present and projected attacks on climate science and scientists by politicians, drawing a link between them and " the pseudo-science that questioned the link between smoking cigarettes and lung cancer, and the false claims questioning the science of acid rain and the hole in the ozone layer.

Tolkien originally described that Eä, the World, was bounded by the Walls of Night, and that the space above the surface of the Earth up to the Walls was divided into three regions ; common birds could keep aloft only within the lower layer, while the Eagles of Manwë could fly " beyond the lights of heaven to the edge of darkness ".

The glass has been described as " a layer 1 to 2 centimeters thick, with the upper surface marked by a very thin sprinkling of dust which fell upon it while it was still molten.

Jung described this deeper layer as " a psychic activity which goes on independently of the conscious mind and is not dependent even on the upper layers of the unconscious — untouched, and perhaps untouchable — by personal experience " ( Campbell, 1971 ).
