Electro-coagulation of the Gasserian ganglion was introduced in Germany by Kirschner in 1931. 1 In recent years, the percutaneous approach to coagulation of the ganglion for treatment of trigeminal neuralgia has gained in popularity. Sweet and Wepsic recently reported on 353 patients stating that "the patient's cooperation is maintained by the use of the neuroleptanesthetic Innovar® and the pro...

The eggshells of drosophilid species provide a powerful model for studying the origins of morphological diversity. The dorsal appendages, or respiratory filaments, of these eggshells display a remarkable interspecies variation in number and shape, and the epithelial patterning underlying the formation of these structures is an area of active research. To extend the analysis of dorsal appendage ...

They enthusiastically agreed that there was a need for such a journal. It seemed likely that the Coordinating Committee for a Nationwide Stroke Program would become the Stroke Council of the American Heart Association (AHA). Such a council would provide a logical administrative structure on which to found the journal. In December 1966, the Central Committee of AHA approved the request for counc...

We study the performance of a stylized supply chain where two firms, a retailer and a producer, compete in a Stackelberg game. The retailer purchases a single product from the producer and afterward sells it in the retail market at a stochastic clearance price. The retailer, however, is budget constrained and is therefore limited in the number of units that he may purchase from the producer. We...

Bupropion is used clinically to treat depression and to promote smoking cessation. It is metabolized by CYP2B6 to its activemetabolite hydroxybupropion, yet alterations in CYP2B6 activity have little impact on bupropion plasma levels. Furthermore, less than 10%of a bupropion dose is excreted as urinary bupropion and its characterized metabolites hydroxybupropion, threohydrobupropion, and erythr...

Governments around the world evaluate economic performance using macroeconomic indicators, such as GDP. In this study emergy accounting was used to assess the economy of Argentina during the 20 century. Emergy evaluations of the Argentine economy for five time periods (1900-1929, 1930-1943, 1944-1975, 1976-1989, and 1990-1995) were conducted. Results were compared with evaluations of other coun...

Few studies have attempted to examine analytically various aspects of the contract enforcement institutions in post-Soviet Russia. Researchers agree that the lack of legislation for improving the operation of the legal system, which in turn would enhance the ability of exchange, is producing severe obstacles for economic growth. After the collapse of the Soviet Union, when the administrative hi...

This paper examines questions about contract enforcement in the absence of formal legal institutions, using archival evidence for one particular rural society in pre-emancipation Russia. The evidence presented indicates that enforcement services provided by the local landlord made it possible for Russians from different socioeconomic and legal strata (soslovii) to engage in a wide variety of co...
