Yellow body

An example of this was a yellow body with a red band on the nose to denote high explosive, lyddite (Picric Acid) filled projectiles. When plaster kits were assembled to these projectiles a wide brown band was painted on the projectile nose and one narrow red band painted underneath it. In addition to the color markings, metal stamp and stencil markings were also employed for identification purposes... 

The LH surge is the primary impetus for ovulation. During ovulation, the mature follicle ruptures, releasing the ovum from the ovary. At this point, the ovum should begin to travel toward the uterus via the fallopian tubes. The ruptured follicle remains in the ovary and continues to play a vital role in the reproductive cycle. After releasing the ovum, the follicle becomes infiltrated with lipids and is referred to as the corpus luteum (yellow body). The role of the corpus luteum is described next. 

Figure 21.6 The Base (Muller-5) mating scheme. Dashed lines represent the treated X chromosome of males. Brackets indicate males with yellow bodies, which would be absent if a lethal mutation occurred on the X chromosome of the treated male.

In aqueous acetic acid solution. The above quantities were again used and the mixture warmed on the water-bath for a da5 A yellow body is obtained, 0-3 gram, decomposing at 180° C. This substance agrees with the formula ... 

In hydrochloric acid. Five grams of chloride in 200 c.c. of water, 0 78 gram of hydrochloric acid (density 1-19), 0 98 gram of propargyl acetal are warmed for a day on the water-bath. An orange-yellow body (5 grams) separates. It sinters at 210° C. and probably has the formula ... 

Sodium naphthylamine sulphonate (5 6 grams) is dissolved in 125 c.c. of boiling water, and a solution of 6 4 grams of mercuric acetate in 25 c.c. of water is poured in. The mixture is boiled for a few minutes, then sodium hydroxide is added dropwise until complete solution is obtained. The whole is then quickly cooled to 70° C. and 150 c.c. of alcohol added, a yellow body being precipitated. The whole is cooled quickly, shaken, and filtered, the residue washed with 50 per cent, alcohol, absolute alcohol, and finally with ether. A pale yellow powder is obtained which corresponds to the formula ... 

Finally, microchemical tests (12), mass spectroscopy (16), and laser-microprobe Raman spectroscopy (16) all fail to show the presence of any added materials on the yellow body-only image fibrils to within their limits of detection. We conclude that no material has been added to these yellowed fibrils to produce the color (12,16). 

In the first, or attached-X visible test, wild-type males (treated and control) are mated to virgin females of an attached-X line (whose X chromosomes should be homozygous for a recessive mutant such as yellow body color). The sons of this mating, which are non-yellow, are examined for any visible mutants. Such mutants are bred again to attached-X females in order to determine whether or not they are transmitted and, if so, to determine whether they are (a) sex-linked recessives (or dominants) or autosomal dominants and (b) complete mutants or mosaics — the latter term signifying mutants that are transmitted as if the original male were a gonadal mosaic for that mutant. 

The formation of lead antimonate, referred to above, is sometimes deliberately encouraged in low-temperature pottery glazes, where a compound of lead oxide and antimony oxide, known as Naples yellow, is used. Antimony is not often used as an opacifier in glazes, but is used in the pottery industry as a yellow body stain, usually in combination with rutile or titanium dioxide.
