Organic characterization

When chromium atoms were cocondensed at 77 K with 1,7-cyclodeca-diyne (38), complexation was not observed however, an organic trimer of the starting material was formed. Standard, organic characterization-techniques showed that this trimer is the one depicted, rather... [Pg.162]

Atherosclerosis is a condition of the organism characterized by elevated levels of atherogenic lipoproteins in blood plasma, lipid deposits (including cholesterol) in the form of esters inside walls of the arterial system, and it is expressed by a gradual difficulty of blood circulation. The most appropriate name for this disease is lipoproteinemia. Clinically, it is manifested in the form of ischemic heart disease, stroke, abnormal cerebral blood flow, and peripheral ischemia. [Pg.269]

Cutaneous Hazards The term refers to a specific target organ characterization of effect. These are chemicals which affect the dermal layer of die body. Signs and symptoms include defatting of the skin rashes irritation. Examples are ketones and chlorinated compounds. [Pg.229]

In a previous paper,22 we investigated the breakthrough dynamics of tert-butylbenzene (TBB) using different activated carbons in dry and wetted beds, and dry and wet airstream. It was shown that the availability of a developed network of mesopores (and macropores as transport pores), a low nonuniformity of pores and surfaces, and a low affinity with respect to water (low content of polar surface sites), are necessary conditions for a high effectiveness of carbon adsorbents in the adsorption of organics characterized by an extension of the critical breakthrough time. [Pg.414]

Because the organic composition of these materials is very complex and the analytical techniques are still not resolved completely, it is impossible at present to give an organic characterization equivalent to the inorganic characterization shown in Tables V, VI, and VII. Our eflForts... [Pg.277]

Arthropods are organisms characterized by exoskeletons and segmented bodies such as crustaceans, insects and arachnids. They are the most diverse and widely distributed animals on the planet. Many arthropod species serve as carriers of bacterial and viral diseases, as intermediate hosts for protozoan and helminth parasites, and as parasites themselves. [Pg.758]

Arthropod—h phylum of organisms characterized by exoskeletons and segmented bodies. [Pg.759]

Anthropod Makes up the largest group of living organisms, characterized by a jointed chitinous exoskeleton, segmented body, and joined appendages, associated with some or all of the segments. [Pg.1111]

Heptanitrocubane (125) is easily soluble in polar solvents, such as acetone, THE, and dichloromethane. Single crystal X-ray analysis of 125 has provided an accurate density at 21 °C of 2.028 g cm and showed many intermolecular contacts around each molecule. A solution of 125 in methanol turned yellow which may be due to the anion. Octanitrocubane (128) is a stable, white solid and somewhat soluble in hexane but readily soluble in polar organics. Characterization of 128 was based on single crystal X-ray analysis [115]. [Pg.76]

A 1997 report in Science and Justice Journal of the Forensic Science Society illustrates the value of organic characterization using GCMS. In this study, the authors employed a static... [Pg.236]
