... the rotating, localized lowering of the cloud base beneath the rain-free portion of a thunderstorm that often precedes tornado development...

CONT

Wall clouds can range from a fraction of a mile up to nearly five miles in diameter, and normally are found on the south or southwest(inflow) side of the thunderstorm. Even though this cloud is lowering, it remains attached to the rain free cloud base of the thunderstorm. It is usually located south or southwest of the visible precipitation area, and marks the strongest updraft in the thunderstorm. The wall cloud develops as the strong updraft draws in surface moisture from several miles away.

OBS

"Wall cloud" also is used occasionally in tropical meteorology to describe the inner cloud wall surrounding the eye of a tropical cyclone, but the proper term for this feature is "eyewall."

Le précurseur typique de la tornade est le mur de nuages. C'est une partie de la base du nuage qui semble s'abaisser vers le sol. On le trouve normalement sur le flanc arrière droit de l'orage. Autrement dit, si l'orage arrive de l'ouest, il faut regarder vers sa partie sud-ouest. Le mur de nuages se forme dans la zone sans précipitations et montre généralement un mouvement de rotation, sous la base du nuage.

Kasugamycin... Use Pattern and Formulations : Kasugamycin is not registered in the U. S. [September 2005], however, tolerances were established to cover residues on imported tomatoes and peppers from Mexico where the registrant is seeking to register Kasumin® 2L, a liquid formulation comprised of 2% kasugamycin(by weight) as the active ingredient(ai), for use on rice, potato, pepper, and tomato in Mexico. The product is formulated from kasugamycin hydrochloride hydrate(2. 3%) and contains 2% kasugamycin(0. 1667 lb ai/gal) as the free base. Kasugamycin is also formulated as a co-active ingredient(at 5%) along with copper oxychloride(at 45%, expressed as copper) in a wettable powder(WP), designated Kasumin Cobre®. Additionally, the Kasumin® formulation is a WP containing 8% kasugamycin.

The comb nephoscope consists essentially of a series of rods assembled in the form of a comb, and mounted on a vertical rod with the "teeth" of the comb horizontal. The vertical rod is free to turn, and is rotated by means of a pulley and rope device. The observer selects a recognizable feature of the cloud base, and then rotates the comb of the nephoscope until that feature appears to move along the longitudinal member of the comb.... By using the "teeth" of the comb, and a timepiece, the observer may time the motion of the cloud. The speed of the cloud may then be determined, provided its height is known.

A sweep ramp provides the tuning voltage for a voltage-tuned oscillator and is simultaneously applied to the horizontal-deflection system of a cathode-ray-tube display. The local-oscillator frequency is mixed with the input signal to produce an intermediate frequency (IF). The IF is detected, filtered, and applied to the vertical deflection plates of the CRT [cathode-ray-tube].

CONT

The receiver has to have suitable pass band characteristics to deal with the pulse modulation side bands, and must be free from paralysis following reception of a large signal... Its output is rectified and amplified and applied to the cathode-ray tube display, either as a deflexion or an intensity modulation. The cathode-ray tube is also supplied with a range time base..., synchronized to the pulse transmission, and suitable calibration devices... are usually also necessary. The form of the display unit depends on the particular radar application, and on what coordinate or coordinates other than range are to be presented. For example, in the plan position indicator the time base starts from the centre of the tube and goes radically outwards in a direction depending on the azimuth of the beamed aerials(which sweeps continuously), and the signal is presented as a spot intensifier.

Glide avalanches ... occur mostly in very steep rock slabs during very warm weather. Glide avalanches are relatively difficult for a person to trigger and they tend to release more or less randomly in time. Paradoxically, they tend to release during the coldest part of the day, or during a freeze following a protracted period of melting ...

CONT

Glide avalanches are very difficult to predict. [Example approved by the Avalanche Bulletin Terminology Standardization Committee.]

OBS

"Glide avalanches" occur when the entire snowpack(from ground to surface) slides slowly downslope. A large crack(called a "glide crack") is formed at the top of the slope, and below this crack is where the snow is slipping down the hill. The rate of glide is variable and based on many factors(not well understood). The two biggest influences are the ground cover(smooth grass and rock slab cause glide) as well as the amount of free water at the base of the snowpack which can lubricate the sliding surface. Often these glide slabs will slip downhill for months, or most of the winter. They are very unpredictable and when they decide to release then we generally get a very large avalanche because the entire snowpack depth to the ground slides. When the glide slab finally releases-that is a "glide avalanche. "[Reference : Grant Statham, Avalanche Specialist, Parks Canada. ]

OBS

Do not confuse "glide avalanche" with "full-depth avalanche". Glide is a slow process that usually occurs over several days, weeks or even months, while a "full-depth avalanche" is a sudden release of a slab avalanche that breaks to the ground.

A supercell with "text-book" like features such as a well-defined hook echo on a radar scope and the precipitation core downwind of the wall cloud and rain free storm base.

CONT

Supercell [is] a thunderstorm with a persistent rotating updraft. Supercells are rare, but are responsible for a remarkably high percentage of severe weather events-especially tornadoes, extremely large hail and damaging straight-line winds. They frequently travel to the right of the main environmental winds(i. e., they are right movers). Radar characteristics often(but not always) include a hook or pendant, bounded weak echo region(BWER), V-notch, mesocyclone, and sometimes a TVS [Tornado Vortex Signature]. Visual characteristics often include a rain-free base(with or without a wall cloud), tail cloud, flanking line, overshooting top, and back-sheared anvil, all of which normally are observed in or near the right rear or southwest part of the storm. Storms exhibiting these characteristics often are called classic supercells; however HP(High Precipitation) storms and LP(Low Precipitation) storms also are supercell varieties.

CONT

The severe version of a worst-last storm is also a supercell type, and is either called a "classic supercell" (the standard supercell type) or an "LP (low-precipitation) supercell" - a dry-weather, high wind shear version. ...

CONT

Free atmosphere [is] in meteorology, the part of the troposphere above the planetary boundary layer. It is free of the influence of the earth’s surface and, on the average, slightly stable.

CONT

The base of the free atmosphere is usually taken as the geostrophic wind level. In practice it is observed that the geostrophic wind level is often between 1 and 2 km, and it is assumed that this marks the upper limit of frictional influence of the earth's surface. The geostrophic wind level may be considered to be the top of the Ekman layer and planetary boundary layer, that is, the base of the free atmosphere.

Procedure based on the formation of a diazo linkage between enzyme proteins and aryldiazonium electrophilic groups on the insoluble support. Supports containing aromatic amino groups are treated with sodium nitrite in acidic solutions and the resultant activated support reacts with aromatic residues such as the phenolic residue of L-tyrosine or the imidazole residue of L-histidine to give azo derivatives.

CONT

There are many commercial diazonium salts used as azo coupling reagents, which are usually in a stabilized form(a stable diazotate) produced by reaction with alkali(forming the free base) or with zinc chloride(forming a diazo double salt)... Diazonium ions are weak electrophiles; they react with highly reactive aromatic compounds-with phenols and tertiary aromatic amines-to yield azo compounds... Azo coupling of proteins can be effected by polymers containing aryldiazonium functional groups... Monomers containing aromatic nitro groups grafted onto polymers have been reduced, diazotized, and used to immobilize enzymes.

The area where teams line up to shoot foul shots, formerly shaped like a key.

CONT

At each end of the court a free-throw lane is marked. It is a rectangle 12 ft wide and extending 19 ft from the end-line. A semi-circle with a radius of 6 ft is drawn from the center of the free-throw lane giving the lane some resemblance to a keyhole. Hence it is normally referred to as the "key". No player is allowed to remain in the key for more than 3 sec. when his team has the possession of the ball.

CONT

From the ends of the foul line to the base line run two lines that form the free throw lane, or foul lane.... In international play the foul lane is 17 feet wide at the base line, and therefore its lines slant outward from the 12-foot-wide free throw lane.

("Unusual" means a base other than A, G, C, or U.) Many of the unusual bases differ from normal bases by the presence of one or more methyl(-CH3) groups. Most, if not all, of the methyl groups are enzymatically added after the nucleotides are linked together by 3’-5’ phosphodiester linkages. Very probably, the other unusual bases also arise by the enzymatic modification of a preexisting polynucleotide. The function of the unusual bases is not yet clear. They are not limited to alanine tRNA but occur in varying proportions in all tRNA molecules. Our only hint of their role is the fact that several unusual bases cannot form conventional base pairs. Some of the unusual bases may thus have the function of disruption double-helical hairpin regions, thereby exposing free keto and amino groups which can then form secondary bonds. Depending upon the specific bases, the free groups may form secondary bonds to template RNA, to a ribosome, or to the enzyme needed to attach a specific amino acid to its specific tRNA molecule. [Examples of those rare nucleotides are : Inosine, 1-methylinosine, N2-dimethylguanosine, 1-methylguanosine, Ribothymidine, Dihydrouridine and Pseudouridine].

Les deux classes de bases trouvées dans tous les mononucléotides sont dérivées de corps aromatiques hétérocycliques appelés purine et pyrimidine. La purine dérive elle-même de la pyrimidine par la fusion d'un cycle pyrimidine et imidazole. Les trois bases pyrimidiques les plus communes sont : l'uracile, la thymine et la cytosine, désignées couramment par U, T et C respectivement. Les bases puriques intervenant le plus souvent comme composantes des mononucléotides sont l'adénine et la guanine, respectivement désignées par A et G. Il existe [aussi] de nombreuses bases rares, telles que la 5-méthylcytosine, ou la 5-hydroxyméthyl-cytosine, [l'ionosine, la pseudouridine, etc...] Le rôle de ces bases rares n'est pas clair pour l'instant. Elles (...) existent en proportions variables dans toutes les molécules de tARN. Seul indice connu sur leur rôle possible, ces bases rares ne peuvent pas s'apparier de la manière habituelle. Certaines de ces bases rares pourraient donc avoir pour fonction de provoquer l'ouverture de quelques régions en épingle à cheveux de la double hélice, exposant ainsi des groupements cétones et aminés libres susceptibles de former des liaisons secondaires. Selon la nature des bases exposées, ces groupements libres pourraient former des liaisons secondaires avec la matrice d'ARN, avec le ribosome ou avec l'enzyme qui attache l'acide aminé à son tARN spécifique.
