The photophores serve as camouflage, since the body appears almost transparent by the light effects and normally visible structures, such as the eyes, lose their sharp outline.

The change between allotropic forms is triggered by the same forces that affect other structures, i. e. pressure, light, and temperature.

Visual beacons range from small, single-pile structures to large lighthouses or light stations and can be located on land or on water.

In the short term, CERTs perform data gathering, especially to locate mass-casualties requiring professional response, or situations requiring professional rescues, simple fire-fighting tasks ( for example, small fires, turning off gas ), light search and rescue, damage evaluation of structures, triage and first aid.

The figure shows the light diffracted by 2-element and 5-element gratings where the grating spacings are the same ; it can be seen that the maxima are in the same position, but the detailed structures of the intensities are different.

* There is no need for mechanical structures to withstand bending forces ; vehicles or hulls can be very light or dispensed with all together

Lacan postulated that the human psyche is determined by structures of language and that the linguistic structures of Hamlet shed light on human desire.

Cnidocytes contain specialized structures called nematocysts, which look like miniature light bulbs with a coiled thread inside.

For instance, in the case of light trespass by white strobe lighting from communication towers in excess of FAA minimum lighting requirements the Federal Communications Commission maintains an Antenna Structure Registration database information which citizens may use to identify offending structures and provides a mechanism for processing consumer inquiries and complaints.

For example, the human eye uses four genes to make structures that sense light: three for color vision and one for night vision ; all four arose from a single ancestral gene.

However, this information is blurred by the fact that, upon illumination, all fluorescently labeled structures emit light, irrespective of whether they are in focus or not.

So an image of a certain structure is always blurred by the contribution of light from structures that are out of focus.

For example, the human eye uses four genes to make structures that sense light: three for color vision and one for night vision ; all four arose from a single ancestral gene.

They generally provide great compressive strength, and are best suited to structures with light transverse loading when the cores remain unfilled.

These structures can fill most of the interior of a cell, giving the membrane a very large surface area and therefore increasing the amount of light that the bacteria can absorb.

Torches were often supported in sconces by brackets high up on walls, to throw light over corridors in stone structures such as castles or crypts.

X-ray crystal structures can also account for unusual electronic or elastic properties of a material, shed light on chemical interactions and processes, or serve as the basis for designing pharmaceuticals against diseases.

To conduct energy at frequencies above the radio range, such as millimeter waves, infrared, and light, the waves become much smaller than the dimensions of the structures used to guide them, so transmission line techniques become inadequate and the methods of optics are used.

These are typically fairly simple structures, capable of distinguishing only light and dark, although some species have large eyes with lenses that may be capable of more sophisticated vision.

New X-ray observations by the Chandra X-ray Observatory show three distinct structures: an outer, horseshoe-shaped ring about 2 light years in diameter, a hot inner core about 3 light-months in diameter, and a hot central source less than 1 light-month in diameter which may contain the superstar that drives the whole show.

An optical system typically has many openings, or structures that limit the ray bundles ( ray bundles are also known as pencils of light ).

These structures may be the edge of a lens or mirror, or a ring or other fixture that holds an optical element in place, or may be a special element such as a diaphragm placed in the optical path to limit the light admitted by the system.

While most astronomical transient sources have simple and consistent time structures ( typically a rapid brightening followed by gradual fading, as in a nova or supernova ), the light curves of gamma-ray bursts are extremely diverse and complex.

The low weight of PRT's small vehicles allows smaller guideways and support structures than mass transit systems like light rail.

In proteins, structures such as alpha helices and beta sheets are chiral, and thus absorb such light.

Other structures of the hair follicle include the oil producing sebaceous gland which lubricates the hair and the arrector pili muscles, which are responsible for causing hairs to stand up.

Frequently ( as in the magnetopause and the magnetotail ) it is intuitively more useful to regard the distribution and flow of plasma as the primary effect, producing the observed magnetic structure, with the associated electric currents just one feature of those structures, more of a consistency requirement of the magnetic structure.

Although producing accurate models remains a challenge when only distantly related template structures are available, it has been suggested that sequence alignment is the bottleneck in this process, as quite accurate models can be produced if a " perfect " sequence alignment is known.

These dipole moments can line up in certain secondary structures ( such as the α-helix ), producing a large net dipole.

The term derives from the Greek (), meaning " grey ", ( “ marrow ”), referring to the grey matter of the spinal cord, and the suffix-itis, which denotes inflammation., i. e., inflammation of the spinal cord ’ s grey matter, although a severe infection can extend into the brainstem and even higher structures, resulting in polioencephalitis, producing apnea that requires mechanical assistance such as an iron lung.

A positive feedback loop is created, producing extravagant physical structures in the non-limiting sex, such as in the male African Long-Tailed Widow Bird ( left ).

Arbuscular mycorrhizas, or AM ( formerly known as vesicular-arbuscular mycorrhizas, or VAM ), are mycorrhizas whose hyphae enter into the plant cells, producing structures that are either balloon-like ( vesicles ) or dichotomously-branching invaginations ( arbuscules ).

A farm is an area of land, or, for aquaculture, lake, river or sea, including various structures, devoted primarily to the practice of producing and managing food ( produce, grains, or livestock ), fibres and, increasingly, fuel.

Although the cotton industry in the Derwent Valley declined, many of the structures associated with the industrial processes associated with producing cotton and worker's housing has survived and there are 838 listed buildings in the conservation area.

Packed encoding rules ( PER ) are ASN. 1 encoding rules for producing a compact transfer syntax for data structures described in ASN. 1, defined in 1994.

Sequence alignments are useful in bioinformatics for identifying sequence similarity, producing phylogenetic trees, and developing homology models of protein structures.

These operations correspond to equivalent manipulations of generating functions, so producing such functions for complicated structures is much easier than with other methods.

Mallika Sarabhai, one of the nation ’ s most intelligent dance professionals, was successful in producing this piece that is innovative, yet flows into the inherent poetic structures of Bhajan with ease.

The genera Huperzia, Phlegmariurus and Phylloglossum, the species of which were generally included in a more broadly defined Lycopodium in older classifications, are treated in the separate family Huperziaceae in some classifications, and are treated so here ; they differ in producing spores in small lateral structures in the leaf axils.

However, the life cycle of Laminaria consists of the diploid generation, that is the large kelp well known to most people, producing sporangia from specialised microscopic structures, which divide meiotically before they are released.

Data obtained from the Japanese surveys found that was necessary to destroy all wooden and brick residential structures, this can reasonably be defined as the pressure capable of producing severe damage.

The formality which Latin had gained through its long written history was often not present in the vernaculars which began producing poetry, and so new techniques and structures emerged, often derived from oral literature.

Critical naturalism therefore prescribes social scientific method which seeks to identify the mechanisms producing social events, but with a recognition that these are in a much greater state of flux than those of the physical world ( as human structures change much more readily than those of, say, a leaf ).

This process of structures ( re ) producing systems is called structuration.

The result was directional solidification processing in which grain boundaries were eliminated by producing columnar grain structures aligned parallel to the axis of the blade, since this is usually the direction of maximum tensile stress felt by a blade during its rotation in an airplane.

The Collins party settlement was improved with permanent structures, and was soon producing produce and meat for sale and barter.

These are :* External structures as conditions of action ; * Internal structures within the agent ; * Active agency, " including a range of aspects involved when agents draw upon internal structures in producing practical action "; and * Outcomes ( as both structures and events ).
