The article focuses on the outlook for industrial capacity, productivity, and economic recovery in postwar Great Britain. A poll by the British Institute of Public Opinion found that citizens were concerned about preventing cyclical unemployment, redistributing the national income, and building up industrial productivity to the prewar level. A report from the Committee on Post-War Problems recommended a collaboration of business and government to reduce mass unemployment and increase the standard of living. Topics include reports by the Conservative Party Organization and the Federation of British Industries, the Labour Party's goal of full nationalization, and expenditures on research.

The article discusses economic planning for postwar Great Britain. This article is based on reports from organizations such as the Association of British Chambers of Commerce, Lever Brothers and Unilever Ltd., and World Trade Alliance. The emphasis is on free enterprise with continuing wartime controls and a collaboration between workers and employers. The Federation of British Industries' report recommends the nation take a stronger position for international collaboration and trade, but is pessimistic about the loss of overseas investments. Topics are wartime productivity in peacetime, industrial self-government with collective action in trade associations, goals of the aircraft manufacturing, shipping, and air transport industries, and regularization of capital development.

The effects of deoxyribonucleic acid (DNA) synthesis inhibition brought about in four different ways—thymidine starvation, nalidixic acid, hydroxyurea, and dnaBmutation—were examined in isogenic strains of Escherichia coliK-12. Three parameters were examined to determine whether there are strict correlations among them: (i) the extent of DNA synthesis inhibition; (ii) cell survival; and (iii) the rate of breakage of DNA molecules. There was no significant correlation between the extent of DNA synthesis inhibition and the rate of viability loss caused by the four DNA synthesis inhibitors, nor was there a strict correlation between the rate of occurrence of single-strand breaks in DNA and loss of viability. During treatment with hydroxyurea (0.1 M), no viability loss was observed and little, if any, single-strand breakage of DNA occurred. Both thymidine starvation and nalidixic-acid (20 μg/ml) treatment resulted in viability loss and breakage of DNA. For these latter two inhibitors, the two events appeared to be associated because greater rates of both viability loss and DNA breakage were observed for nalidixic acid compared with thymidine starvation. However, viability loss need not be associated with extensive breakage of DNA as demonstrated with a temperature-sensitive DNA synthesis mutant; at 39 C, viability loss occurred at a high rate without significant DNA breakage. With the other agents, the amount of DNA breakage accumulated when a cell population has sustained an average of one lethal hit was estimated to be about 30 single-strand breaks per genome. Differences in chromosomal and episomal breakage rates were observed.
