(Biphenyl-2-yl)bromidobis(2-methyltetrahydrofuran-[kappa]O)magnesium(II) [PDF]
In the title Grignard reagent, [MgBr(C12H9)(C5H10O)2], the Mg centre adopts a distorted tetrahedral MgCO2Br arrangement. The dihedral angle between the two aromatic rings of the biphenyl residue is 44.00 (14)°. Each molecule incorporates one R- and one S-

Characteristics of E. coli K12 strains carrying both an F prime and an R factor [PDF]
The interrelationship between an F prime and an F-like or I-like R factor was studied in Escherichia coli K 12 strains carrying both. The donorability of such strains suggested that these plasmids were transferred independently by their own transfer ...

An efficient method for LEED crystallography [PDF]
Determination of periodic surface structures from analysis of LEED intensity data is usually based on the evaluation of continuous I/V-spectra for a large number of model structures for which all the structural parameters have to be refined ...

Structure determination of the reconstructed Au(110) surface [PDF]
The LEED pattern of the Au(110) surface shows a (1 × 2) and also a (1× 3) superstructure. The (1 × 2) superstructure has been determined by comparison of LEED intensities with model calculations. The missing row model is the most probable model.

R Factors from Serratia Marcescens [PDF]
In recent years, Serratia marcescens has become established in certain localities as an agent of hospital infection and cross-infection (Clayton & von Graevenitz, 1966; Wilfert, Barrett & Kass, 1968; Davis, Foltz & Blakemore, 1970; Wilkowske, Washington, Martin & Ritts, 1970). In general, strains of S.

R Factors from Proteus morganii [PDF]
Summary: Twenty-eight R factors transmissible to Escherichia coli K12 were derived from 178 naturally occurring strains of Proteus morganii and evidence was found of non-transmissible resistance plasmids in some strains. Nine plasmids were assigned to group N; one P. morganii strain carried two N plasmids which were incompatible in reference strains of

4,4´-[4,4´-(Perfluoropropane-2,2-diyl)-bis(4,1-phenyleneoxy)]dianiline [PDF]
In the title compound, C27H20F6N2O2, the dihedral angles between the planes of the aromatic rings connected by the ether O atoms are 84.13 (8) and 75.06 (9)°. The crystal structure is stabilized by N-H...O and N-H...F hydrogen bonds.

Unstable Mutants of R Factor [PDF]
ABSTRACTThirty mutants sensitive to tetracycline were obtained from an R100 factor capable of conferring resistance to tetracycline (TC), chloramphenicol (CM), streptomycin (SM) and sulfanilamide (SA). Among the TC sensitive mutants, three showed a high frequency of spontaneous loss from host strains.

The need for continuous recording rain gauges makes it difficult to determine the rainfall erosivity factor (Rfactor) of the Universal Soil Loss Equation in regions without good spatial and temporal data coverage.
