Figure 5 showed the effect of ultrasonic frequency on degradation of sulfa antibiotics by Fe VI -US in diFe VI -USH condinions.
Ultrasonic frequency in experiments was 200, 400, 600, and 800 kHz, respectively, the initial concentration of sulfamethoxazole was 0.02 mmol·L−1, and the output electric power was 100 W, studying the effect of ultrasonic frequency on degradation of sulfa antibiotics by Fe VI -US.
This also means that for every fixed size of reflector there exists a band of optimal THz frequencies and the focusing ability is severely degraded at higher frequencies because of degradation of graphene's surface conductivity.
At high frequency, the possibility of degradation at the sites near the branching points of LCB increases.
Compared to rim15Δ cells, sch9Δ rim15Δ cells exhibited a more efficient G1 arrest and a reduced frequency of apoptotic DNA degradation during nutrient depletion (Figs. 1A and B).
Feeding of high charges at low frequencies causes an accumulation of degradation products and by-products.
The performance of these communications links are measured by the average signal-to-noise ratio over a period of time, the magnitude of transient noise, the degree of degradation of frequency, phase and amplitude characteristics over a period of time, and what period of time, over a year, the link is available for uninterrupted use.
In tropical dry forest systems (Janzen 1988), grass intrusion and other habitat modifications driven by anthropogenic disturbance can yield widely different outcomes depending on the degree of degradation and frequency of perturbation.
Therefore, we chose a degradation frequency of 1 20 for all following computations.
The pyocyanin level comes close to the maximal level for frequencies of 1 7 or less and reaches this value at a degradation frequency of 1 20 or less.
The effects of magnetic induction, sound pressure level, and sound frequency on the degradation rate of formaldehyde were investigated.
