Soluble Amyloid [Beta] Oligomers Affect Dielectric Properties by Membrane Incorporation and Domain Formation: Implications for Cell Toxicity

October 12, 2021
Author(s)
G Valinius, K F. Heinrich, R Budvytye, David J. Vanderah, Y Sokolov, J Hall, M Losche
Water-soluble prefibrillar amyloid b (Ab1 42) oligomers affect model bilayers by greatly reducing the membrane barrier to ion transport, as previously reported for Ab in many papers. However, important signatures of the molecular transport mechanism are

Some Properties of Irregular 3-D Particles

October 12, 2021
Author(s)
Michael A. Taylor, Edward Garboczi, S T. Erdogan, D Fowler
This paper discusses some of the properties of irregular particles that are of interest to engineers, including volume, density, & surface area. Numerical and statistical information on these properties is essential (a) for a better understanding of

Some Statistical Methods Applicable to Key Comparisons Studies

October 12, 2021
Author(s)
Hariharan K. Iyer, Chih-Ming Wang, Dominic F. Vecchia
Results of International Key Comparisons of National Measurement Standards provide the technical basis for the Mutual Recognition Arrangement formulated by Le Comite International des Poids et Mesures. With many key comparisons already completed and a

Space Charge Characterization for the 21st Century

October 12, 2021
Author(s)
G Damamme, C LeGressus, A S. DeReggi
The various methods of characterizing insulating materials by their ability to take up charge, retain it, and release it are reviewed critically in search of measurable quantities that could be used to predict material behavior under stress up to failure

Species Formation and Burning Characteristics of Scaled Propane Compartment Fires

October 12, 2021
Author(s)
C J. Wieczorek, U Vandsburger, J E. Floyd
Fires occurring in dense occupancies such as hospitals, dormitories, and nursing homes pose a serious threat to occupants due to the risk of carbon monoxide poisoning. This risk is becoming increasingly important as the population demographics of developed

Specific DNA Binding to CRP Induces Conformational Changes in the CRP and the DNA in Solution: A Small-Angle Neutron Scattering Study

October 12, 2021
Author(s)
Susan T. Krueger, S. K. Gregurick, Y. Shi, S. Wang, B Waldkowski, Frederick P. Schwarz
The transcription activator, 3'-5' cyclic adenosine monophosphate (cAMP) receptor protein (CRP), when ligated with cAMP, activates the transcription of over 25 operons, which code for enzymes involved in carbohydrate metabolism in E. coli. Small-angle

Spectral Data for Gallium: Ga I through Ga XXXI

October 12, 2021
Author(s)
T Shirai, Joseph Reader, Alexander Kramida, J Sugar
The energy levels and spectral lines of gallium atom in all stages of ionization have been compiled. Experimental data on spectral lines and energy levels exist for spectra Ga I through Ga VII, Ga XXIII through Ga XXVI, and Ga XXX. For Li-like Ga XXIX

Spectrum and Energy Levels of the Nd 4+ Free Ion (Nd V)

October 12, 2021
Author(s)
Ali Meftah, J-F Wyart, Jocelyne Sinzelle, Wan-U Lydia Tchang-Brillet, Norbert Champion, Nissan Spector, J Sugar
The spectrum of neodymium excited by a sliding spark source was photographed on two vacuum ultraviolet normal-incidence spectrographs. About 250 lines attributed to Nd V, hitherto unknown, have been identified. The analysis of this spectrum established all
