Estimating the rainfall erosivity factor from monthly precipitation data in the Madrid Region (Spain)

open access: yesJournal of Hydrology and Hydromechanics, 2015
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.

Unstable Mutants of R Factor [PDF]

open access: yesJapanese Journal of Microbiology, 1969
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.

R Factors from Serratia Marcescens [PDF]

open access: yesJournal of General Microbiology, 1975
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.

Interbacterial Transfer of R Factor in Humans [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 1973
In vivo interbacterial transfer of R factor was observed in two patients. Resistance to ampicillin, tetracycline, streptomycin, and chloramphenicol was transferred from Escherichia coli in the intestine of a patient with shigellosis to a Shigella sonnei strain.
