CMOS subnanosecond true-ECL output buffer
Autor: H.-J. Schumacher, Evert Seevinck, Jan Dikken
Publikováno v: IEEE Journal of Solid-State Circuits. 25:150-154
An emitter coupled logic (ECL) 100 K compatible output buffer circuit fabricated in a submicrometer CMOS-only process is presented. High speed (0.9-ns delay) and sufficient precision are achieved through the use of a novel circuit principle. Negative

Teratological evaluation of FD&C red no. 2—A collaborative government‐industry study. I. Introduction, experimental materials, and procedures
Autor: H. J. Schumacher, Joseph F. Holson, T. F. X. Collins, David W. Gaylor, G. L. Kennedy, D. I. Ruggles
Publikováno v: Journal of Toxicology and Environmental Health. 1:851-856
Because of recent studies indicating possible embryolethality and teratogenicity of FDC Red. No 2, and ad hoc committee was convened by the Food and Drug Administration to consider these questions. The committee suggested a collaborative study by thr

Kinetics and the mechanism of the thermal reaction between trifluoromethylhypofluorite and hexafluoropropene
Autor: M. dos Santos Afonso, H. J. Schumacher
Publikováno v: International Journal of Chemical Kinetics. 16:103-115
The kinetics of the thermal reaction between CF3OF and C3F6 have been investigated between 20 and 75°C. It is a homogeneous chain reaction of moderate length where the main product is a mixture of the two isomers 1-C3F7OCF3 (68%) and 2-C3F7OCF3 (32%

Kinetics of the thermal decomposition of bis-pentafluorine sulfur peroxide in the presence of carbon monoxide
Autor: H. J. Schumacher, J. Czarnowski
Publikováno v: International Journal of Chemical Kinetics. 10:111-116
The thermal decomposition of F5SOOSF5, P, in the presence of CO has been investigated between 130.1° and 161.9°C at total pressures between 50 and 600 torr. The reaction is homogeneous, and the only final products formed are CO2 and S2F10. The rate

Kinetics of the thermal decomposition of bis-pentafluorosulfur trioxide(SF5O3SF5) in the presence of carbon monoxide
Autor: H. J. Schumacher, J. Czarnowski
Publikováno v: International Journal of Chemical Kinetics. 11:1089-1096
The thermal decomposition of SF5O3SF5 in the presence of CO has been investigated between -9.8°C and + 9.9°C. Besides traces of S2F10, equimolecular amounts of SF5O2SF5 and CO2 are formed. The reaction is homogeneous. Its rate is proportional to th

Strain differences in histopathologic, hematologic, and blood chemistry changes induced in mice by a technical and a purified preparation of 2,4,5‐trichlorophenoxyacetic acid
Autor: B. Highman, H. J. Schumacher, T. B. Gaines, Thomas J. Haley
Publikováno v: Journal of Toxicology and Environmental Health. 1:1041-1054
Including controls, 978 mice were studied. On days corresponding to days 6 through 14 of pregnancy, groups of pregnant and nonpregnant CD-1 mice and male and nonpregnant female dihybrid cross F2 mice received by gavage 2,4,5-trichlorophenoxyacetic ac

The kinetics and the mechanism of the thermal gas-phase reaction between NO2 and 1,1-dichlorodifluoroethylene, CF2CCl2
Autor: J. Czarnowski, H. J. Schumacher
Publikováno v: International Journal of Chemical Kinetics. 18:907-917
The kinetics of the gas phase reaction between NO2 and CF2CCl2 has been investigated in the temperature range from 50 to 80°C. The reaction is homogeneous. Three products are formed: O2NCF2CCl2NO2 and equimolecular amounts of CINO and of O2NCF2C(O)C
