The addition of preservative to spiked blanks and spiked samples should be carried out a few hours after spiking; this time delay permits physical interaction between the sample matrix and the spiking solution. In reporting the analytical results on the spikes, both the absolute concentrations and ...
Using T1 gradient-echo and STIR sequences for caries detection was feasible and accurate in this clinical sample. The STIR sequence might offer advantages compared to conventional radiation-based dental imaging and clinical inspection with regard to detection of clinically asymptomatic lesions with unknown...
A Python code was written to cycle through each combination of possible independent variables with the maximum number of independent variables kept less than or equal to four given the small sample size. For each iteration, the variable inflation factor (VIF) was calculated to assess multi-...
Asset management GCN-DQN Rancho Solano Zone III Novel problem setup to test resilience post-earthquake. Use of GCN as function approximator and transfer learning greatly improves results. (Fan et al., 2022) Stormwater systems Flood control DQN, DDQN, PPO1, PPO2, A2C, Voting Sewer system in...
Sample mean and 95%ile are tested whether they are significantly higher than the class boundaries at a confidence level of 99%, and both t test results are used to determine the physicochemical status following the scheme described above. In the Bayesian approach, the uncertainty of classifi- ...
Fifteen (15) water samples were collected from 15 shallow groundwater sources (depths < 30 m) within three areas (TCA, UA, and PUA) in Ibadan metropolis. The concentration of each analyzed quality indicator in each water sample is presented in the study. Water samples from five hand-du...
Statistical analysis of the concentration of different parameter in water sample around the study area and corresponding WHO recommended value of those different parameters are tabulated in Table 4. Calcium is a major cations found in water which makes water hard. Calcium constitutes our body’s bone...
Results Progressive water deficit was found to effect changes in leaf water potentials accompanied by metabolic changes. In both cultivars, but more intensively in Shiraz than Cabernet Sauvignon, water deficit caused a shift to higher osmolality and lower C/N ratios, the latter of which was also ...
A summary of tentative results regarding non-target screening is shown in Table3. A total of 16 out of 248 analytes were detected in at least one water sample, with occurrence frequency varying substantially between types of drinking water (Table3, Supplementary Table2). Non-filtered tap water...
Bacteria removal test Domestic river water was used as raw sewage for the bacteria source. Water condensed from the vapour generated by GAH was collected as purified sample. The river water and the GAH-purified water to be tested were diluted 10,000 times, and then 1 ml was evenly applied...
