Detection of carcinogens as mutagens in the Salmonella/microsome test: assay of 300 chemicals.
Proceedings of the National Academy of Sciences of the United States of America, 1975 About 300 carcinogens and non-carcinogens of a wide variety of chemical types have been tested for mutagenicity in the simple Salmonella/microsome test.

CRYOHAEMORRHOIDECTOMY A REVIEW OF 300 CASES [PDF]
Medical Journal Armed Forces India, 1997 Three hundred patients, comprising of 210 men and 90 women, with internal haemorrhoids (grade I and II) were subjected to cryosurgery. There was good destruction of piles in 270 (90%) patients while in 30 (10%) patients residual pile mass was present requiring further treatment The result was compared with 100 patients of grade II haemorrhoids who ...

Database of Absorption and Fluorescence Spectra of >300 Common Compounds for use in PhotochemCAD
Photochemistry and Photobiology, 2018 The design of new molecules for photochemical studies typically requires knowledge of spectral features of pertinent chromophores beginning with the absorption spectrum (λabs) and accompanying molar absorption coefficient (ε, m−1 cm−1) and often ...

Room-Temperature Structures of Solid Hydrogen at High Pressures [PDF]
J. Chem. Phys. 137, 074501 (2012), 2012 By employing first-principles metadynamics simulations, we explore the 300 K structures of solid hydrogen over the pressure range 150-300 GPa. At 200 GPa, we find the ambient-pressure disordered hexagonal close-packed (hcp) phase transited into an insulating partially ordered hcp phase (po-hcp), a mixture of ordered graphene-like H2 layers and the ...

Imaging at 300 MHz With the MWA [PDF]
arXiv, 2021 At relatively high frequencies, highly sensitive grating sidelobes occur in the primary beam patterns of low frequency aperture arrays (LFAA) such as the Murchison Widefield Array (MWA). This occurs when the observing wavelength becomes comparable to the dipole separation for LFAA tiles, which for the MWA occurs at approximately 300 MHz.

Electronic Transport through YBCO Grain Boundary Interfaces between 4.2 K and 300 K [PDF]
Phys. Rev. Lett. 92, 257003 (2004), 2003 The current-induced dissipation in YBCO grain boundary tunnel junctions has been measured between 4.2 K and 300 K. It is found that the resistance of 45 degree (100)/(110) junctions decreases linearly by a factor of four when their temperature is increased from 100 K to 300 K.

Electrical and Thermal Transport of Layered Bismuth-chalcogenide EuBiS2F at temperatures between 300 and 623 K [PDF]
J. Phys. Soc. Jpn. 84, 085003 (2015), 2015 We demonstrate the electrical and thermal transport of layered bismuth-based sulfide EuBiS2F from 300 to 623 K. Although significant hybridization between Eu 4f and Bi 6p electrons was reported previously, the carrier transport of the compound is similar to those of F-doped LaBiS2O, at least above 300 K.
