Water disinfection is an essential process that provides safe water by inactivating pathogens that cause waterborne diseases. However, disinfectants react with organic matter naturally present in water, leading to the formation of disinfection by-products(DBPs). Multi-analyte methods based on mass spectrometry(MS) are preferred to quantify multiple DBP classes at once however, most require extensive sample pre-treatment and significant resources. In this study, two analytical methods were developed for the quantification of 32 regulated and unregulated DBPs. A purge and trap(P&T) coupled with gas chromatography mass spectrometry(Gc-MS) method was optimized that automated sample pre-treatment and analyzed volatile and semi-volatile compounds, including trihalomethanes(THMs), iodinated trihalomethanes(I-THMs), haloacetonitriles(HANs), haloketones(HKTs) and halonitromethanes(HNMs). LOQs were between 0.02-0.4 μg/L for most DBPs except for 8 analytes that were in the low μg/L range. A second method with liquid chromatography(Lc) tandem mass spectrometry(MS/MS) was developed for the quantification of 10 haloacetic acids(HAAs) with a simple clean-up and direct injection. The Lc-MS/MS direct injection method has the lowest detection limits reported(0.2-0.5 μg/L). Both methods have a simple sample pre-treatment, which make it possible for routine analysis. Hyperchlorination and uniform formation conditions(UFc) formation potential tests with chlorine were evaluated with water samples containing high and low TOc. Hyperchlorination formation potential test maximized THMs and HAAs while UFc maximized HANs. Ascorbic acid was found to be an appropriate quencher for both analytical methods. Disinfected drinking water from four water utilities in Alberta, canada were also evaluated.

In our previous studies, we demonstrated the usefulness of TanDEM-X interferometric bistatic mode with single polarization to obtain forest heights for the purposes of large area mapping. A key feature of our approach has been the use of a simplified Random Volume Over Ground(RVOG) model that locally estimates forest height. The model takes TanDEM-X interferometric coherence amplitude as an input and uses an external Digital Surface Model(DSM) to account for local slope variations due to terrain topography in order to achieve accurate forest height estimation. The selection of DSM for use as a local slope reference is essential, as an inaccurate DSM will result in less accurate terrain-correction and forest height estimation. In this paper, we assessed TanDEM-X height estimates associated with scale variations in different DSMs used in the model over a remote sensing supersite in Petawawa, canada. The DSMs used for assessments and comparisons included ASTER GDEM, ALOS GDSM, airborne DRAPE DSM, canadian DSM and TanDEM-X DSM. Airborne Laser Scanning(ALS) data were used as reference for terrain slope and forest height comparisons. The results showed that, with the exception of the ASTER GDEM, all DSMs were sufficiently accurate for the simplified RVOG model to provide a satisfactory estimate of stand-level forest height. When compared to the ALS 95th height percentile, the modeled forest heights had R2 values greater than 80% and Root-Mean-Square Errors(RMSE)less than 2 m. For a close similarity in slope estimation with the ALS reference, coverage across canada and open data access, the 0.75 arc-second(20 m) resolution canadian DSM was selected as a preferred choice for the simplified RVOG model to provide TanDEM-X height estimation in canada.

The neurophysiological measurement technique known as magnetoencephalography, or MEG, has been in use since the early 1970's, and applied to clinical populations since the early 1980's. However, it was not until the late 1980's and early 1990's that the technology was advanced to point where effective clinical use was achieved. This presentation will review the basic principles of MEG, discuss the progression of technology development and give an update on the current clinical applications of the technology.

In 1981 a magnetic and bathymetric survey was carried out over Explorer Seamount located approximately between 48°50′ and 49°30′N and 130°40′ and 131°30′W. During the cruise four pillow fragments were dredged from peaks in this area. Based on the observed ***, it was identified that the main peak of Explorer Seamount should be of the Bruhnes age while the magnetic high in the N W of study area would be Gauss. This would yield a spreading rate of about 2 cm per year for the Matuyama epoch. The results of intensities of remanence measured from the pillow fragments indicate that the ages are less than 106 years. Similarly the curie temperature is consistent with ages of around 106 years. An attempt was made to model the observed magnetic field using a series of uniformly magnetized NE-SW trending blocks of alternating polarity. Agreement between the model and observed results is satisfied. Oxidation ratios calculated from measured samples suggest that the main peak of Explorer Seamount is
