Soil and Water Research, 2019 Rainfall erosivity is the main factor of the USLE or RUSLE equations. Its accuracy depends on recording precision and its temporal resolution, number of stations and their spatial distribution, length of recorded period, recorded period, erosion rainfall

Characteristics of E. coli K12 strains carrying both an F prime and an R factor [PDF]
, 1970 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 ...

R Factors in Hospital Infection [PDF]
BMJ, 1972 In order to assess the clinical importance of R factors 524 "coliform" infections were studied in a general hospital. Of these, 95 were caused by Pseudomonas aeruginosa. Among the remaining 429, 43% were caused by drug-resistant enterobacteria; resistance was frequently multiple and determined by transmissible R factors.

Comparison of Rain Erosivity Models (Factor R) Using Statistical Analysis [PDF]
Anuário do Instituto de Geociências, 2018 Comparison of rain erosivity models (Factor R) using statistical analysis. Modeling natural systems contributes to the understanding of the landscape variations, associated to the potential of renewable resources and the natural environments fragilities.

Approximability of Connected Factors [PDF]
, 2013 Finding a d-regular spanning subgraph (or d-factor) of a graph is easy by Tutte's reduction to the matching problem. By the same reduction, it is easy to find a minimal or maximal d-factor of a graph. However, if we require that the d-factor is connected,

Host Ranges of R Factors [PDF]
Journal of General Microbiology, 1972 SUMMARY: All R factors so far described can be transmitted to Escherichia coli. F-like R factors are transmissible to the Proteus group but not to the Pseudomonadaceae. Among fi - R factors, I-like plasmids are not transferable to Proteus although they mediate conjugation, allowing transfer of other plasmids to this group. They are not transmissible to

, 2012 We consider some aspects of nonlocal modified gravity, where nonlocality is of the type $R \mathcal{F}(\Box) R$. In particular, using ansatz of the form $\Box R = c R^\gamma,$ we find a few $R(t)$ solutions for the spatially flat FLRW metric.

R factors from Providence [PDF]
Microbiology, 2000 Of more than 100 R factors transferred from naturally occurring Providence strains, approximately 60 % belonged to the A-C compatibility complex. Plasmids of groups F1, J, N, P and X, and the prototype of a new group G were also transferred. The Providence R factor set differs from those of Proteus rettgeri and P.
