Recent interest in renewable energy production has exponentially increased the utilization of ethanol, a biofuel produced largely from corn in the United States. Increased production of ethanol has redistributed corn from livestock production to ethanol production. In 2002, 11% of the US corn crop was used in ethanol production; with the increase in production as much as 30% of US corn was bein...

In this paper, we aim to investigate the coordination of interlocutors behavior in different emotional segments. Conversational coordination between the interlocutors is the tendency of speakers to predict and adjust each other accordingly on an ongoing conversation. In order to find such a coordination, we investigated 1) lexical similarities between the speakers in each emotional segments, 2)...

A virus, inactivated by ultraviolet light, was used to fuse together cells from different species of vertebrate, and the resulting heterokaryons were examined by autoradiographic and cytological techniques. Heterokaryons could be made with both differentiated and undifferentiated cells: HeLa and Ehrlich ascites cells were studied as examples of undifferentiated cells; rabbit macrophages, rat ly...

When primitive erythroid cells from 5-day-old chick embryos are exposed to inactivated Sendai virus they do not undergo haemolysis but fuse with other cells by the normal process of cytoplasmic coalescence. In this way cells actively engaged in the synthesis of haemoglobin may be fused with others that are not. In heterokaryons formed by the fusion of such erythroid cells with cells from establ...

The heterokaryotic condition, first described by Dodge (1927) in N. tetrasperma, provided a ready means for determining the dominance of traits expressed in the haploid vegetative phase. Heterokaryons also seemed to offer a novel genetic system, in contrast to diploidy. The advent of recessive auxotrophic mutations in 1941 provided a means of selecting heterokaryons composed of strains with com...

A fourth mutant of Neurospora crassa, designated frq-4, has been isolated in which the period length of the circadian conidiation rhythm is shortened to 19. +/- 0.3 hours. This mutant is tightly linked to the three previously isolated frq mutants, and all four map to the right arm of linkage group VII about 10 map units from the centromere. Complementation tests suggest, but do not prove, that ...
