Cyanobacteria have far more simplistic and less redundant NH4/NO3 assimilation pathway which may complicate the dynamic response to mixed nitrogen media additions; nitrogen-fixing cyanobacteria present an additional challenge that may preclude this pH strategy all-together.
In addition to the protein network of bacterial motility [14], we here present an additional network of DNA metabolism for T. pallidum, which is solely based on high-throughput data and bioinformatical predictions (Figure 4A, see Discussion S1 and Table S3 for an extended discussion).
But warplanes present an additional problem.
Unpredictable weather patterns are increasing mortality as well, and the escalating intensity and frequency of fires in forests and on the tundra present an additional threat.
It's a challenge to study the cognitive abilities of any creature that lacks language, but human babies present an additional difficulty, because, even compared to rats or birds, they are behaviorally limited: they can't run mazes or peck at levers.
Supplemental (bottled) oxygen breathed through a mask can partially alleviate the effects of hypoxia, but it can present an additional problem if a climber becomes used to the oxygen and then runs out while still at high altitude.
Special Feature: Martin Gardner's Life in Pictures I'm also honored to present an additional surprise this week — a slide show of Mr. Gardner with his family and friends that also includes personal reflections by Mr. Gardner's son Jim.
The green and blue colored deformations present an additional bending, such that the amount of bending on yz-plane decreases.
We also present an additional boundary condition for the phase field function, which together with the usual Dirichlet condition can work effectively as the phase-field inflow conditions.
We present an additional unusual complication of ill-fitting maxillary dentures in an edentulous patient, previously not reported in the literature.
In the additional file, we present an additional calculation in which we incorporate the effects of mantle depletion in the major elements, by integrating the melt extraction and by calculating the subsequent melting according to the degree of depletion.
