Anaerobic benzene degradation in culture and hydrocarbon degradation in the subsurface environment
No full textUnderstanding of microorganisms and pathways involved in anaerobic benzene degradation is limited. Stable isotope probing of DNA was used to identify key members of a previously characterized, sulfate-reducing benzene degrading consortium. DNA extracts of cultures incubated with [13C6]- or [12C6]benzene were separated into 13C- and 12C-labeled fractions by CsCl density gradient centrifugation. Sequencing and Terminal Restriction Fragment Length Polymorphism (T-RFLP) analysis of the 16S rRNA gene identified TRF 270 (bp), a Desulfobacterium like phylotype, which was first to derive the bulk of the 13C label for DNA synthesis, and is thus likely involved in activation of benzene degradation.
To understand the pathway of anaerobic benzene metabolism, degradation and inhibition tests were used. Based on these tests toluene was eliminated, and benzoate was identified as a possible intermediate. Metabolites detected in cultures amended with [13C6]benzene or [13C6]phenol indicate that in this consortium there are 2 different pathways of benzoate formation, one forms universally labeled ([13C-UL]benzoate), and the other forms ring labeled benzoate. Pathway that forms [13C-UL]benzoate is dominant during benzene degradation in which the benzene ring is carboxylated by a carbon derived from another benzene ring. This pathway is different from the proposed pathway of benzene degradation via phenol, as the labeling pattern of 13C-labeled benzoate formed from [13C6]benzene or [13C6]phenol is not identical. In conclusion, a novel pathway that activates one benzene ring through its reaction with products of another benzene ring likely exists in this consortium.
Groundwater impacted by a manufacturing gas plant site was used for detection and quantification of metabolic intermediates of polycyclic aromatic hydrocarbons and gene analogues encoding alpha subunit of benzylsuccinate synthase (bssA), as evidence for natural attenuation. Highest concentrations of metabolic intermediates of anaerobic naphthalene and 2-methylnaphthalene degradation were detected in an impacted monitoring well (MW)-24, near the source. Quantitative analysis of 16S rRNA gene indicated that bacterial population was enriched in the impacted wells, while bssA gene containing bacterial community was enriched in MW-24. Detection of not one, but two different indicators specific to the presence and activity of microorganisms provides strong evidence for in situ anaerobic microbial processes.Ph.D.Includes bibliographical referencesby Amita R.

No full textAmita Baviskar’s latest book titled Uncivil City: Ecology,
Equity and the Commons in Delhi provides an in-depth analysis of
exclusion of the Commons from the socio-economic and political spaces of
inarguably India’s most powerful city; Delhi. The book is divided into
three sections with eights chapters encompassing book’s themes. It
starts with setting the context by explaining the reasons for titling
the book as ‘Uncivil City’. Conceptualising Delhi as Uncivil expounds
the City’s changing spatial dynamics which the author has detailed by
analysing City’s social history by doing socio-historical analysis. She
also reminisces her early-life experiences with the City; what the City
was for the Commons in the past; how infrastructural development has
excluded the Commons; what the City’s formal politics and politicised
environment is doing to the Commons and what does future entail for
them
Partition asymptotics; zeros of zeta functions; and Apéry-like numbers
No full textPART I
G. H. Hardy and S. Ramanujan established an asymptotic formula for the number of
unrestricted partitions of a positive integer, and claimed a similar asymptotic formula for
the number of partitions into perfect kth powers, which was later proved by E. M. Wright.
Recently, R. C. Vaughan provided a simpler asymptotic formula in the case k = 2. In the
first part of the thesis, we study the number of partitions into parts from a specific set
Ak(a0; b0) :={mk : m 2 N;m _ a0 (mod b0)}, for fixed positive integers k, a0; and b0. Using
the Hardy-Littlewood circle method, we give an asymptotic formula for the number of such partitions, thus generalizing the aforementioned results of Wright and Vaughan. We also consider the parity problem for such partitions and prove that the number of such partitions is even (odd) infinitely often, which generalizes O. Kolberg's theorem for the ordinary partition function. This material builds on the joint work with B. C. Berndt and A. Zaharescu.
PART II
The Riemann Hypothesis implies that the zeros of all the derivatives of the Riemann-_
function lie on the critical line. Results on the proportion of zeros on the critical line of derivatives of _(s) have been investigated before by B. Conrey, and I. Rezvyakova. The percentage of zeros of _(k)(s) on the critical line approaches 100% percent as k increases. The second part of this thesis builds on the joint work with S. Chaubey, N. Robles, and A. Zaharescu. We study the zeros of combinations of derivatives of _(s). Although such combinations do not always have all their zeros on the critical line, we show that the proportion of zeros on the critical line still tends to 1.
PART III
The third part of this thesis focuses on the work on Apéry-like numbers joint with Armin
Straub. In 1982, Gessel showed that the Apéry numbers associated to the irrationality of
_(3) satisfy Lucas congruences. Our main result is to prove corresponding congruences for all known sporadic Apéry-like sequences. In several cases, we are able to employ approaches due to McIntosh, Samol-van Straten and Rowland-Yassawi to establish these congruences. However, for the sequences labeled s18 and (_) we require a finer analysis. As an application, we investigate modulo which numbers these sequences are periodic. In particular, we show that the Almkvist-Zudilin numbers are periodic modulo 8, a special property which they share with the Apéry numbers. We also investigate primes which do not divide any term of a given Apéry -like sequence.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2019-08-01The student, Amita Malik, accepted the attached license on 2017-07-13 at 10:11.The student, Amita Malik, submitted this Dissertation for approval on 2017-07-13 at 10:40.This Dissertation was approved for publication on 2017-07-13 at 13:58.DSpace SAF Submission Ingestion Package generated from Vireo submission #11450 on 2017-09-29 at 11:19:20Made available in DSpace on 2017-09-29T17:52:21Z (GMT).

From the sources distributed and transported to local restaurants, then prepared, served, and eventually eaten by consumers, food is a significant part of Chengdu's culture. Eating is not only just about the food itself, but also about where to eat, how to eat, when to eat, whom to eat with. Culinary heritage is proposed to be conserved through the concept of ""tastescape"", which is planned as a combination of landscape and culture in which eating becomes a situated event. The design study focuses on the streets in historic neighborhoods in the inner city of Chengdu. The relationship between food, landscape and culture, and tastescape is proposed by combining eating with participating in theaters, local artworks, and cooking."Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-08-01The student, Linna Yi, accepted the attached license on 2016-07-21 at 14:46.The student, Linna Yi, submitted this Thesis for approval on 2016-07-21 at 15:13.This Thesis was approved for publication on 2016-07-22 at 09:52.DSpace SAF Submission Ingestion Package generated from Vireo submission #10042 on 2016-11-10 at 12:27:36Embargo set by: Seth Robbins for item 95396

Housing design for land-lost farmers in Suzhou, China
No full textWith the reform and opening-up policy launched since the 1980s, China's economy has been growing rapidly. With this background, urbanization has been on a fast track. However, rapid urbanization resulted in many problems. One of these problems was that more and more farmers were losing their land. The land-lost farmers usually live a difficult life and their new housing usually lacks many cultural features that they have been used to. This thesis proposes a socially and culturally appropriate housing design as a tool to help relieve the above mentioned problems of the land-lost farmers.
In order to alleviate the problems, design patterns are used as principles in this housing design project. The principles are applied based on the specific site context. The principles are generated from A Pattern Language to meet the special requirements of the land-lost farmers. They are also based upon vernacular housing and the traditional culture in the Yangtze delta region.
The study site is located in Suzhou, a typical city with many land-lost farmers. Two possible site designs are proposed in this thesis. They are applications of design patterns and can be used at other sites in China.Item withdrawn by Mark Zulauf ([email protected]) on 2014-08-15T21:03:50Z

Nanjing City Wall: embodied heritage in wallscape
No full textNanjing City Wall is one of the largest city walls in China. As the capital of Ming Dynasty between 1368-1420 CE, the wall was built to protect the city. A four-wall system separated the royal palace in the city from the countryside. After approximately six hundred years of damage by humans and nature, the importance of this ancient heritage was realized. However, as the wall has been nominated to be a UNESCO World Heritage Site, the government is implementing its preservation policy to sanitize the surrounding neighborhoods which are in poor condition. The preservation plan puts too much emphasis on picturesque landscapes. As such, by reviewing the history and representations of the City Wall, the thesis studies the important relationship between the wall, adjacent landscape and the entire city. Mapping and analysis of city wall is done to critique the current conservation policy. Design strategy is proposed to envision potential of the wall as heritagescape.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2019-08-01The student, Kaichao Wang, accepted the attached license on 2017-07-21 at 10:18.The student, Kaichao Wang, submitted this Thesis for approval on 2017-07-21 at 10:43.This Thesis was approved for publication on 2017-07-21 at 11:31.DSpace SAF Submission Ingestion Package generated from Vireo submission #11575 on 2018-03-02 at 13:03:09Made available in DSpace on 2018-03-02T20:02:40Z (GMT).
