Investment Climate in China: province estimates

YesThis paper uses a large firm-level survey to assess differences in performance across regions. A panel data analysis is conducted to explain both productivity and profitability across firms in terms of firm and industry characteristics. Regional dummies are included to pick up additional location-specific impacts and the size of these dummies is used to rank provinces. Province performance is then examined in terms of geography, infrastructure, the policy environment and aspects of the investment climate with the conclusion that the latter plays a major part in explaining provincial differences in performance

DES Working Paper No 2: 'Changing Trade Structure and Its Implications for China'

Based on the insight that the type of product an economy exports can have important implications for its economic performance and that goods exported predominantly by rich countries will have different characteristics from those exported by poor countries, Lall et al (2006) put forward a novel means of classifying commodities based on the income levels of a product¿s main exporters. At around the same time Hausmann et al (2006) following a similar approach put forward a slightly different form of product classification and Rodrik (2006) applied this specifically to an analysis of China. This paper highlights the difference between the approaches and its implications for the analysis of China, which appears less `special¿ using the approach of Lall et al

Requirement for the coexpression of T3 and the T cell antigen receptor on a malignant human T cell line.

The association between T3 and the T cell antigen receptor was examined using the T3 bearing T cell leukemic line Jurkat. A monoclonal antibody, C305, was produced, which reacted with idiotypic-like determinants expressed on Jurkat. The molecule with which this antibody reacted was a disulfide-linked heterodimer of 90 kD, composed of polypeptides of 42 and 54 kD. Thus, C305 reacted with a molecule with characteristics of the putative T cell antigen receptor described by others. A series of mutants of Jurkat, induced with ethyl methane sulfonate or radiation, was selected for T3 or antigen receptor negativity. In every instance, there was a concomitant loss of both T3 and the antigen receptor as assessed by quantitative absorption, indirect immunofluorescence, and antibody plus complement-mediated cytotoxicity. The absence of antigen receptor molecules was confirmed on diagonal gels, excluding the possibility that conformational changes of the antigen receptor on such T3-negative mutants were responsible for the failure of such mutants to react with C305. Moreover, in a mutant that expressed a marked decrease in the level of T3 expression, there was a comparable decrease in the expression of antigen receptor determinants. These results suggest that there is an obligate requirement for the coexpression of T3 and the T cell antigen receptor. Furthermore, attempts to activate such mutants with the lectin phytohemagglutinin suggested that the expression of T3 and/or the antigen receptor was required for activation of these cells

Fabrication of a glycerol from CO2 reaction system, supplement

The fabrication, installation, and testing of a glycerol hydrogenation and a CO2 hydrogenation - CH4 partial oxidation units are reported. The glycerol system proved to be operational while the CO2 system was installed but not bought on operational steam
