Multi-point monitoring of nitrous oxide emissions and aeration efficiency in a full-scale conventional activated sludge tank
In this work the biological tank of a WRRF in Italy was monitored placing five floating hoods on a plug-flow-like biological aerated tank surface in order to capture emission dynamics in both time and space domains. The five hoods report which location is more responsible for N2O production at a certain moment of the day. Moreover, with this experimental investigation, a spatial shift in N2O production towards the end of the biological tank could be detected. This provides important insights in the changes in biological dynamics especially with varying incoming load
DEVISE AND ORGANIZING OF ENERGY IN PV SRM DRIVES FOR ELECTRICAL VEHICLES
Electric motors are automobiles, which is probably powered via the use of the use of the electrical engine and electric powered power. To triumph over the one's issues a photovoltaic panel and a switched reluctance motor can be used for power shipping and motor power. In order to decrease the power conversion strategies, one method is to rework the motor to embody a few onboard charging functions. The solar energy usage and most power component tracking (MPPT) are suitable elements for the PV-fed electric powered automobiles. In order to gain inexpensive and bendy electricity drift modes, a unique low-price tri-port converter is proposed in this paper in a way to coordinate the PV panel, SRM, and battery. To assist flexible control energy flow six operational modes are evolved. Due to the trap 22 state of affairs of cutting-edge battery technology, the usage of range is probably very short. In giving a boost to, in phrases of motor drives, immoderate-regular typical overall performance eternal-magnet (PM) machines are notably used. In PM machines there may be no trouble winding and the sphere is furnished thru the out of doors magnet. Most typically unusual earth materials are used. But they'll be very dearer
Preventing the Reintroduction of Malaria in Mauritius: A Programmatic and Financial Assessment
Sustaining elimination of malaria in areas with high receptivity and vulnerability will require effective strategies to prevent reestablishment of local transmission, yet there is a dearth of evidence about this phase. Mauritius offers a uniquely informative history, with elimination of local transmission in 1969, re-emergence in 1975, and second elimination in 1998. Towards this end, Mauritius's elimination and prevention of reintroduction (POR) programs were analyzed via a comprehensive review of literature and government documents, supplemented by program observation and interviews with policy makers and program personnel. The impact of the country's most costly intervention, a passenger screening program, was assessed quantitatively using simulation modeling
Quantification of greenhouse gas emissions in biological wastewater treatment
There is an increasing need to reduce greenhouse gas (GHG) emissions and to identify
influencing factors from wastewater treatment plants (WWTPs), particularly process
emissions consisting of nitrous oxide (N2O), and methane (CH4) GHG, with global
warming potentials about 310 and 21 times higher than carbon dioxide (CO2)
respectively (IPCC, 2006). However, the challenges offered by full-scale environments,
have to date, restricted a real-time, comprehensive approach of monitoring emissions
and influencing factors. This study aimed at addressing this knowledge gap, by
reporting the findings of a long-term, online, continuous monitoring of GHG emissions
and operational variables. Lanes were monitored in nitrifying activated sludge plants
(ASP) controlled under ammonia (NH4
+
) and dissolved oxygen (DO) set-points (DO setpoints
monitored: 1.5 and 2.0 mg/L), as well as in a biological nutrient removal plant
(BNR) under NH4
+
control.
The findings showed that CH4, although potentially formed in non-aerated
compartments, was emitted in aerobic zones, at an average emission factor (EF) of
0.07 % of influent and removed chemical oxygen demand (COD). Nitrous oxide EFs on
the other hand, depended on relative nitrogen fractions, with influent-based EFs
showing a best-case scenario, at 0.05–0.72 % of both influent total nitrogen (TN) and
NH4
+
, compared to the higher EFs based on removed nitrogen at 0.13–3.9 % of TN and
NH4
+
removed. The processes operated under the same control settings (DO set-point
1.5 mg/L), had similar, or identical, EF, suggesting that settings could help predict the
range of EF. Nitrous oxide was always produced in the presence of NH4
+
, even at low
concentrations (=<0.5 mg/L), therefore linking N2O production with NH4
+
oxidation,
particularly with nitrifier nitrification. Incomplete denitrification under low carbon to
nitrogen (C/N) ratios also triggered N2O production (EFs of 2.4 and 4.1 % of reduced TN
at C/N ratios of 2.8 and 2.4 respectively), particularly with intermittent aeration.
Therefore, nitrifier denitrification and incomplete denitrification simultaneously
occurred and triggered N2O production in the final stages of nitrification. The BNR lane
was the most operationally stable process, therefore offering the best balance
between efficiency (60–99 % less aeration and energy per kg of treated NH4
+
), low
carbon footprint and reduced EFs (0.08–0.1 % of all nitrogen fractions). The second
best option was the DO set-point control of 1.5 mg/L, with low EFs (0.05–0.2 %), stable
operational conditions and reduction in aeration requirements (up to 340 % less than
DO set-point 2.0 mg/L). Operating ASP under NH4
+
control however, led to 7–96 %
more efficiency than under DO set-points, although it required better control in the
back end of the process.
Only an online, long-term methodology such as adopted in this study, could provide
insights into emission variability and the effect of operational variables on promoting
or reducing emissions. Based on this, strategies to mitigate emissions at full-scale were
recommended
Unseen Histories: A Visual Study of Political Presence and Aesthetic Interpretation
My thesis explores different attempts made to counter a visual occupation that has a fixed frame on the supposed ·\u27criminal,\u27\u27 such as Elia Suleiman\u27 s films, Claudia Rankine\u27s poetry and short videos, and Korryn Gaines\u27s sousveillance of her traffic stop and the day of her shooting. In considering all of these, I strive to illuminate ethical ways of watching the videos we encounter that practice what Simone Browne calls \u27·dark sousveillance.\u27· I use my research to (re)consider the ways one can watch Konyn Gaines\u27s videos as an attempt at freedom for the more of us. By doing so, I begin to find and explore the contours of the visual practices and ways of seeing that are required of us as fellows in a relationship built on a promise or trust that we will see injustice and act to maintain sanctuary cities. My visual study was inspired by attempts to retool language and visuality as a gesture towards emancipation. The first chapter is followed by an interlude--a spoken word piece that accompanied a visual piece I had created combining the recent Pepsi ad that gestures towards peace with the police and the community meeting in Portland where a person was escorted out by police for enacting the same gesture in the ad. The second interlude is an annotated version of the Great Barrington Trust Policy, which I felt important to include not only because of its current topicality, but because it is implicated in conversations of politics, visuality, citizenship, surveillance, policing, and most importantly (to my project), community building. The final interlude, a letter to my sister, concludes my thesis on a note of creating new relationships with old friends through newer modes of thinking about seeing, knowing, and believing
Exploring the use of big data in auditing: evidence from external auditors in Portugal
This Work Project provides evidence of the use of Big Data in auditing in Big 4and non-Big 4auditfirms in Portugal. Based on five interviews and a questionnaire submitted to 46 auditors, the research concludes that auditors value the use of Big Data in auditing, although they confuse the concept of Big Data with Data Analytics and are not yet fully utilising it. Lack of knowledge on the subject is an obstacle as is resistance to change. The research recommends leadership commitment and increase in education about Big Data as key drivers to ease its use in auditing
