Condition for local absolute continuity to imply uniform continuity

  1. Given that [itex]x\left(t\right)[/itex] is locally absolutely continuous, and [itex]\dot{x}=f\left(x,t\right)[/itex] exists almost everywhere, is it possible to place a condition on [itex]f\left(x,t\right)[/itex] to allow us to show that [itex]x\left(t\right)[/itex] is uniformly continuous? Perhaps that [itex]\dot{x}=f\left(x,t\right)[/itex] is locally uniformly bounded in t? But I'm not sure how to prove this and have not been able to find any specific resources that point to this fact.

    I understand that absolutely continuous functions are by nature uniformly continuous, and if [itex]x\left(t\right)[/itex] is differentiable everywhere and [itex]\dot{x}=f\left(x,t\right)[/itex] is bounded everywhere, the [itex]x\left(t\right)[/itex] is UC. However, I am at a loss as to how to extend UC to these measure variations.

    Thanks for any help!
