THE METAMORPHOSIS OF HEMOGLOBIN IN THE BULLFROG [PDF]

open access: yesJournal of General Physiology, 1951
1. Tadpole and adult hemoglobin do not differ significantly in molecular weight. The molecular weight of both is in the neighborhood of 68,000. 2. Heme-heme interaction as measured by the value of n in Hill's equation is virtually the same—about 2.8—in both tadpole and adult. 3. There appears to be no significant effect of

Histocompatibility Genetics of Bullfrog Populations [PDF]

open access: yesEvolution, 1961
Genetic studies of anuran species have been limited for the most part by failure of the F1 generation to reach maturity under laboratory conditions. Thus data on backcross and F2 progenies are not available and the mode of inheritance even of overt traits such as pigment patterns remains problematical (Anderson and Volpe, 1958).

Data Schema Evolution for the Self‐Adaptive Software Domain: A Systematic Mapping Study

open access: yesSoftware: Practice and Experience, EarlyView.
ABSTRACT Context Self‐adaptive Software (SaS) is a special category of software systems that enables adaptation at runtime to address new user requirements or changes in its execution environment. This article focuses on a specific category of SaS named SaS2DB, which encompasses systems that require the storage of data in a database. In short, a SaS2DB
