Appropriate technologies (AT) are only a fraction of the solution in achieving sustainable and safe access to water and sanitation worldwide.
Nylon-6 in formic acid solvent was allowed to degrade by simply allowing it to stand for a long time, and nanofibrous mats were fabricated by taking a fraction of this solution at different time intervals via electrospinning under the same electrospinning conditions.
It is plausible that the solutions of these experiments are only a fraction of the solutions that people think are good.
If the neighbor solution has a better objective function value, it is accepted as the new solution, while a fraction of non-improving solutions are accepted in the hope of escaping local optima in search of global optima.
Since the underlying algorithmic problem is computationally hard, these mechanisms cannot always achieve the optimal welfare; Nevertheless, they do guarantee a fraction of the optimal solution.
The new electrode prototype proved to be able to monitor EEG signals similar to those of the commercial silver/silver chloride electrodes by using a fraction of the hydrating solution necessary for the commercial electrodes, thus avoiding to damage or dirtying the patient's hair.
To normalize protein expression to the total cellular protein, a fraction of the lysate solution was used in a Bradford protein assay.
Given that one of the two binding sites on SEA is a weak binding site of micromolar affinity [1], [21], we hypothesized that there may exist a fraction of SEA in solution that remained bound to DR1 through only one binding site.
A fraction of the KO2 solution (e.g., ∼1 2 μL) was transferred to an anaerobically sealed assay vial that contained an assay buffer (1 mL).
To normalize protein expression to total cellular protein, a fraction of the lysate solution was used in a Bradford protein assay.
In brief, a fraction of the assay solution containing KO2 was transferred to an anaerobically sealed vial that contained oxidized ferricytochrome c (10 μL).
