Stigmas

The most important considerations in marketing and estabUshing a crop from a new source are constancy of supply and quahty. Eor some spices, it is difficult to reduce labor costs, as some crops demand individual manual treatment even if grown on dedicated plantations. Only the individual stigmas of the saffron flower must be picked cinnamon bark must be cut, peeled, and roUed in strips mature unopened clove buds must be picked by hand and orchid blossoms must be hand pollinated to produce the vanilla bean. 

Saffron. Saffron spice is the dried stigmas of Crocus sativus L. (Iridaceae), a bulbous perennial native to southern Europe and Asia Minor and cultivated in the Mediterranean countries, particularly Spain. Tme saffron should not be confused with either meadow saffron, ie, Colchicum autumnale L. (Lihaceae) also called safflower, or bastard saffron, ie, Carthamus tinctorius L. (Compositae), both of which are occasionally used to adulterate tme saffron.

In the United States, outside of the core areas of older major cities, transit has become the transport of last resort. There is a substantial social stigma attached to using transit, due to the low income levels of transit patrons in most U.S. cities. Transit customers also sometimes fear their vulnerability to crime, especially while waiting at bus stops. 

Saffron is the tiny stigma at the center of the crocus flower, Crocus sativus. Because each stigma is plucked from the flower by hand, saffron is one of the most expensive spices in use today.

Stage 3 (fully opened) flowers were collected, dissected and cell wall proteins (5 pgm) from the indicated organs isolated and analyzed for p-subunit antigen. Note the high level of expression in stigma/style and anthers/pollen and restriction of the larger antigen to stigma/style tissues. PGl lane, 1 gg of purified fruit PGl protein.

The stigma attached to mental illness is pervasive and affects the lives of people with mental illness. It makes the patient reluctant to come forward and ask for help. It makes rehabilitation after an episode of illness difficult. It contributes to the loss of self-esteem of the person who has the illness, a consequence that is particularly nefarious because it often blocks full recovery. Stigma also affects the members of the family, making them reluctant to admit that one of them has a mental illness and may need treatment, ft demeans institutions in which treatment is provided as well... 

As a result of Frankland s out-of-wedlock birth, he became a painfully shy man who shunned publicity. His courage arose from his convictions that the public deserved clean drinking water and that students deserved a sound scientific education. Thus, Frankland s life as a chemist is also the story of how a dedicated scientist overcame the stigma of illegitimacy in socially rigid Victorian England. 

As nylon and the plastics revolution became a part of modern life, the figure of Carothers receded tragically into the shadows. The horror of his death, the social stigma attached to mental illness and suicide, and prevailing social codes that discouraged the discussion of personal tragedies contributed to an atmosphere of secrecy that surrounded his life. As late as 1979, the Encyclopaedia Britannica credited Father Nieuwland with the discovery of Neoprene. 

The composition of cutin shows species specificity although cutin from most plants contains different types of mixtures of the C16 and C18 family of acids. Composition of cutin can vary with the anatomical location. For example, cutin preparations from fruit, leaf, stigma, and flower petal of Malus pumila contain 73%, 35%, 14%, and 12%, respectively, of hydroxy and hydroxy-epoxy C18 monomers [23]. In general, fast-growing plant organs have higher content of C16 family of monomers.
