A mutant of Bombyx mori has wings with few scales and is named scaleless. We investigated the morphology of this mutant and found that it had many fewer wing scales than the corresponding wild type (WT) silkworm and that the remaining scales were smaller in shape with fewer furcations. Reciprocal transplantation of wing discs between scaleless and WT revealed that the WT wing disc could develop...

the study evaluated the body weight during growth (bwg), body weight at slaughter (bws), breast meat yield (bmyg), percent breast meat yield (bmy) and breast meat quality (colour and drip loss) of genetically featherless (scsc) broilers compared to their feathered sibs under hot conditions. two hundred featherless chicks and 200 feathered sibs were reared under hot conditions in two rooms (aver...

As a tool for human spatial cognition and thinking, the map has been playing an important role. Maps are perhaps as fundamental to society as language and the written word. Economic and social development requires extensive and in-depth understanding of their own living environment, from the scope of the overall global to urban housing. This has brought unprecedented opportunities and challenge...

1. Rates of water loss were measured in two aberrant scaleless water snakes, Natriu sipedon, and in six normal animals. 2. Pulmocutaneous water loss of the scaleless animals was equal to or less than that of the controls at 20, 27, and 34°C. 3. The thermal dependence of pulmocutaneous water loss in all snakes was low (Q,, = 1.31-1.89). 4. The proportion of total water loss due to cutaneous evap...

Lepidopteran wing scales and Drosophila bristles are considered homologous structures on the basis of the similarities in their cell lineages. However, the molecular mechanisms underlying scale development are essentially unknown as analysis of gene function in Lepidoptera is sorely limited. In this study, we used the Bombyx mori mutant scaleless (sl), which displays a nearly complete loss of w...

The idea of a seamless, scaleless data base of digital spatial data for use in auto mated cartography or geographic information systems has intrigued researchers for a number of years. Yet reviewing the plans of mapping agencies in the United States and Europe for their digital data bases in the 1990's shows partitioning by scale, space, and time. Why is this so? Is a seamless, scaleless data b...

I give a new account of neg-raising with belief predicates as scaleless implicatures, inferences that are predicted by grammatical theories scalar when quantifier projects subdomain alternatives but no alternative. argue the inference should be treated an implicature because parallels observed in its distribution and other known cases implicatures (namely typical free choice effects, reported i...
