The Antidumping Act and the Future of East-West Trade

Because of the peculiarities of price formation in Communist countries, both with regard to export commodities and those intended for domestic consumption, the applicability of traditional antidumping concepts to communist price discrimination, and the usefulness of the Antidumping Act of 1921 in coping with it, are questions which should be examined and resolved before moves toward freer trade between East and West reach full stride. The essence of the problem was captured in a 1963 statement by the then Senator Humphrey: The present act is ineffective in preventing dumping from communist countries, which can control their home prices by state fiat. It is the purpose of this study to illustrate and explore various aspects of the problem and to offer alternative methods of dealing with it

The Quantitative Identification of E-6 Chemical Processing Errors

This thesis contains descriptions of current methods of identifying chemical processing errors, followed by a description of a proposed method for quantitatively identifying chemical processing errors. The goal of this research is to determine the relationships between chemical deviations in the first developer of Kodak Color Reversal Process E-6 and the resulting changes in the sensitometric parameters of Kodak film type Ektachrome 64 Professional (Daylight). These relationships are presented in graphical form in a section of this thesis entitled Results and Conclusions

Improved ceramic slip casting technique

A primary concern in modern fluid dynamics research is the experimental verification of computational aerothermodynamic codes. This research requires high precision and detail in the test model employed. Ceramic materials are used for these models because of their low heat conductivity and their survivability at high temperatures. To fabricate such models, slip casting techniques were developed to provide net-form, precision casting capability for high-purity ceramic materials in aqueous solutions. In previous slip casting techniques, block, or flask molds made of plaster-of-paris were used to draw liquid from the slip material. Upon setting, parts were removed from the flask mold and cured in a kiln at high temperatures. Casting detail was usually limited with this technique -- detailed parts were frequently damaged upon separation from the flask mold, as the molded parts are extremely delicate in the uncured state, and the flask mold is inflexible. Ceramic surfaces were also marred by 'parting lines' caused by mold separation. This adversely affected the aerodynamic surface quality of the model as well. (Parting lines are invariably necessary on or near the leading edges of wings, nosetips, and fins for mold separation. These areas are also critical for flow boundary layer control.) Parting agents used in the casting process also affected surface quality. These agents eventually soaked into the mold, the model, or flaked off when releasing the case model. Different materials were tried, such as oils, paraffin, and even an algae. The algae released best, but some of it remained on the model and imparted an uneven texture and discoloration on the model surface when cured. According to the present invention, a wax pattern for a shell mold is provided, and an aqueous mixture of a calcium sulfate-bonded investment material is applied as a coating to the wax pattern. The coated wax pattern is then dried, followed by curing to vaporize the wax pattern and leave a shell mold of the calcium sulfate-bonded investment material. The shell mold is cooled to room temperature, and a ceramic slip is poured therein. After a ceramic shell of desired thickness has set up in the shell mold, excess ceramic slip is poured out. While still wet, the shell mold is peeled from the ceramic shell to expose any delicate or detailed parts, after which the ceramic shell is cured to provide a complete, detailed, precision ceramic article without parting lines

Impedanzspektroskopie im SystemCoFe2O4 - MnFe2O4

Die technisch bedeutsame Gruppe der Ferrite ist hinsichtlich ihres Chemismus so vielfältig, wie es auch die physikalischen Eigenschaften sind und bietet immer noch ein weites Feld für Forschungen. In der vorliegenden Arbeit sind die Ergebnisse zusammengefaßt, die der Autor im bislang noch wenig untersuchten System MnFe2O4 – CoFe2O4 bei der Synthese und der Erforschung der magnetischen und elektrischen Charakterisierung im Blick auf die strukturellen Unterschiede zusammengetragen hat. Dabei kommen vor allem Neutronenbeugungsuntersuchungen, Mößbauerspektroskopie, SQUID-Messungen und Impedanzspektroskopie zum Einsatz

Caenorhabditis elegans pathways that surveil and defend mitochondria

Mitochondrial function is challenged by toxic byproducts of metabolism as well as by pathogen attack1,2. Caenorhabditis elegans normally responds to mitochondrial dysfunction with activation of mitochondrial repair, drug detoxification, and pathogen-response pathways1–7. From a genome-wide RNAi screen, we identified 45 C. elegans genes that are required to upregulate detoxification, pathogen-response, and mitochondrial repair pathways after inhibition of mitochondrial function by drugs or genetic disruption. Animals defective in ceramide biosynthesis are deficient in mitochondrial surveillance, and addition of particular ceramides can rescue the surveillance defects. Ceramide can also rescue the mitochondrial surveillance defects of other gene inactivations, mapping these gene activities upstream of ceramide. Inhibition of the mevalonate pathway, either by RNAi or statin drugs also disrupts mitochondrial surveillance. Growth of C. elegans with a significant fraction of bacterial species from their natural habitat causes mitochondrial dysfunction. Other bacterial species inhibit C. elegans defense responses to a mitochondrial toxin, revealing bacterial countermeasures to animal defense
