Filter-based measurements of aerosol optical absorption are widely used to determine Black carbon（Bc） concentrations in real time. Measurements at multiple wavelengths（Sandradewi 2008） can identify the contributions from different combustion sources, separating ‘Black carbon’（Bc） from ‘Brown carbon’（Br c）. These methods sometimes show non-linearity due to ‘loading effects’ of increasing aerosol deposit on the filter（gundel, 1984;Weingartner, 2003;Arnott, 2005;Virkkula, 2007）. These effects are highly variable and cannot be treated by static.a.gorithms, either in post-processing of the data or fixed in the instrument firmware. A dynamical and auto-adaptive approach is required, in order to capture the details and variability of the aerosol optical properties and allow for accurate real-time source apportionment. We have developed a new Aethalometer?, Model AE33, in which two parallel sampling channels collect the aerosol simultaneously at different loading rates. combining the data from the two parallel analyses eliminates the ‘loading effect’ and yields an accurate measurement of Bc together with a dynamical value of the non-linearity parameter which is indicative of aerosol properties. These analyses are performed for multiple optical wavelengths spanning the range from 370 nm to 950 nm and with a time resolution as rapid as 1 second. The results show greatly improved analytical performance for measurement of Bc. The instrument is network-ready and is designed for both research and routine monitoring operations. We present results from the use of this new instrument in urban and rural measurement campaigns in Switzerland, France, Austria, and Slovenia. The data show high sensitivity and time resolution, with a complete absence of loading artifacts. We have developed a real-time application based on a published method（Sandradewi, 2008） for source apportionment to separate contributions of biomass and fossil fuel combustion to ambient aerosols.

Tolpyralate is a new benzoylpyrazole herbicide for weed management in corn. It is recommended to be co-applied with atrazine along with the adjuvants methylated seed oil concentrate (MSO) plus an ammonium nitrogen fertilizer, such as urea ammonium nitrate (UAN). Two studies were conducted on glyphosate-resistant (gR) canada fleabane and gR waterhemp to determine if an additional adjuvant is still required when tolpyralate plus atrazine are tankmixed with a commercial glyphosate formulation (Roundup WeatherMAX®) in corn. Trials were conducted over a two-year period (2018-19) on farms in south western Ontario with confirmed gR populations. When co-applied with Roundup WeatherMAX®, the addition of MSO to tolpyralate + atrazine increased control of gR waterhemp 9%;however, there was no increase in gR canada fleabane control from the addition of additional adjuvants. At 8 WAA, all treatments provided > 91% and > 84% control of gR waterhemp and gR canada fleabane, respectively. This study concludes that the addition of Roundup WeatherMAX®to tolpyralate plus atrazine improves the control of gR waterhemp and gR canada fleabane in corn.

Aim: To validate a Vietnamese short version (OhIP- 14VN) for use in epidemiological studies. Methods: The original English-language version was translated into Vietnamese, back translated and after some revisions tested for psychometric properties. Subjects (n = 724) were asked to self-administer a questionnaire but could ask for assistance. convergent validity was tested by investigating associations between OhIP domain and total scores, and dichotomized self-reported satisfaction with 1) the dentition in general, 2) chewing function, and 3) esthetics. groups validity was evaluated by comparing OhIP scores of subjects having ≤6 molars vs. >6 molars and tooth decay vs. no decay. Test-retest reliability was investigated in a convenience sample (n = 54) and expressed in Intraclass correlation coefficients (Iccs). Internal consistency was assessed by cronbach’s alpha and average interitem correlation coefficients. Results: Validity: all associations were in the hypothesized directions. Differences in mean OhIP total were statistically sig-nificant for all discriminative variables. OhIP scores completed with assistance were significantly lower than those from self-administered questionnaires and therefore analyzed separately. For both administration formats differences in mean scores were still significant for “satisfaction” but for having ≤6 molars or decay the differences lost significance for most domain and total scores. Reliability: Iccs ranged from 0.54 - 0.74. Internal consistency: cronbach’s alphas for OhIP total scores were 0.93 (self-administered) and 0.91 (with assistance). Average interitem correlation coefficients ranged from 0.26 - 0.67 (self-administered) and 0.28 - 0.69 (with assistance). conclusions: This Vietnamese version of the OhIP-14 demonstrated good construct validity and acceptable reliability for OhIP total scores however OhIP-14VN domain scores should be interpreted with caution.

Synthesis gas, composed of h2 and cO, is an important fuel which serves as feedstock for industrially relevant processes, such as methanol or ammonia synthesis. The efficiency of these reactions depends on the h2: cO ratio, which can be controlled by a careful choice of reactants and catalyst surface ***, using a combination of environmental scanning electron microscopy(ESEM) and online mass spectrometry, direct visualization of the surface chemistry of a Ni catalyst during the production of synthesis gas was achieved for the first time. The insertion of a homebuilt quartz tube reactor in the modified ESEM chamber was key to success of the setup. The nature of chemical dynamics was revealed in the form of reversible oxide-metal phase transitions and surface transformations which occurred on the performing catalyst. The oxide-metal phase transitions were found to control the production of synthesis gas in the temperature regime between 700 and 900 ℃ in an atmosphere relevant for dry reforming of methane(DRM, cO2: ch4=0.75). This was confirmed using high resolution transmission electron microscopy imaging, electron energy loss spectroscopy, thermal analysis, and c18O2 labelled *** dedicated operando approach of simultaneously studying the surface processes of a catalyst and its activity allowed to uncover how phase transitions can steer catalytic reactions.
