To investigate the behaviour of volcanic ash upon reheating, we have performed experiments at ten temperature steps between 700 and 1600°C on (1) fresh volcanic ash from the final explosive phase of the 2010 Eyjafjallajökull (EYJA) eruption and (2) two standard materials used in ingestion tests in the history of turbine testing (MIL E 5007C test sand, MIL; Arizona Test Dust, ATD).
Certainly, ingestion tests with standard sands cannot be reliable proxies for the thermal risk of volcanic ash in turbines.
Thus, ash ingestion tests should be performed to constrain the effect of ash concentration and total load.
We stress as well that ingestion tests should not only investigate the turbine's response to ash concentration (g/m3) but also to ash dosage.
The first performance results of data ingestion tests indicated that MongoDB had a lower latency with simple write operations, but AsterixDB outperformed MongoDB, when multiple elements were saved in a batch over representational state transfer (REST) API [45].
After collecting a pre-test sample to exclude prior ingestion of test sugars, participants drank this solution at time 0, and then urine samples were collected for exactly 5 hours and preserved with merthiolate (approximately 0.04% final concentration).
Two hours after LM ingestion, the test is stopped; if an infant has not passed any urine, the test is extended until urine is collected.
Changes to appetite sensation scores were evident over time after ingestion of test meals (p < 0.05).
Likewise, breath hydrogen concentrations obtained from patients who were unable to absorb all of the ingested carbohydrate were analyzed at baseline and at different time points after ingestion of the test meal (positive test).
During the 4 h after administration or ingestion of the test meal, a C breath test was performed ((11, 13, 14)) on breath samples obtained using an exclusive nasal cannula connected to an infrared spectrometer (Breath ID System; Exalenz Bioscience, Modiin, Israel) that analyzes the ratio of CO2 to CO2 in each breath sample.
