The author reflects upon the roles of language and poetics, the distinction between book and text, and how politics and power affect the making and reception of these works. 2 bibl. ref
Book review: paper tiger: law, bureaucracy and the developmental state in Himalayan India by Nayanika Mathur
No full textFollowing eighteen months of intensive fieldwork, in Paper Tiger: Law, Bureaucracy and the Developmental State in Himalayan India author Nayanika Mathur details the everyday absurdities of bureaucracy in the Himalayan borderlands, showing the frequent gulf between ‘real life’ and the abstract workings of the law.

FINANCING COMMUNITY FACILITIES: A CASE STUDY OF THE PARKS AND RECREATIONAL GENERAL OBLIGATION BOND MEASURE OF SAN JOSE, CALIFORNIA
No full textThis study of the City of San Jose’s Parks and Recreation General Obligation (GO) Bond Measure seeks to identify the politics-, management-, and planning-related lessons learned by the City as it developed its community facilities using the GO bonds proceeds. The study finds that these lessons include: be conservative in what you promise the residents; be prepared for changes in economic environment by identifying supplementary funding sources should the primary source not yield adequate funds; make sure that the jurisdiction is organizationally capable of handling the increased workload; and prepare detailed project plans prior to the bond issuance.Community Infrastructure and Services; Municipal Bonds; Public Finance
An Analytical Criterion for Centrifugal Instability in Non-Axisymmetric Vortices
No full textNon-axisymmetric vortices are ubiquitous in nature; examples include polar vortices in planets, the giant red spot in Jupiter, tornadoes and cyclones on Earth, mesoscale eddies in the ocean. Turbulent flows are furthermore known to be dominated by small- and large-scale vortex structures. Owing to the wide range of applications, knowledge of conditions under which a given vortex becomes unstable is beneficial. Here, the centrifugal instability of two-dimensional, non-axisymmetric vortices in the presence of an axial flow and a background rotation is studied using the local stability approach. The local stability approach, based on geometric optics and similar in formulation to the rapid distortion theory \cite{bib:godeferd2001}, considers the evolution of shortwavelength perturbations along streamlines in the base flow. This approach, developed by Lifschitz Hameiri \cite{bib:lifschitz1991}, is particularly useful for base flows for which a global stability analysis is computationally expensive. A sufficient criterion for centrifugal instability in an axisymmetric vortex with and is first derived by analytically solving the local stability equations for wave vectors that are periodic upon evolution around a closed streamline. This criterion is then heuristically extended to non-axisymmetric vortices and written in terms of integral quantities on a streamline. The criterion is then shown to be accurate in describing centrifugal instability over a reasonably large range of parameters that specify Stuart vortices and Taylor-Green vortices
An experimental investigation of the effects of base bleed in axisymmetric supersonic flow
No full textBase bleed is a technique wherein a small quantity of fluid is injected into the base region of a projectile to reduce the base drag. The effects of base bleed on the near-wake flowfield of a cylindrical afterbody in a Mach 2.5 flow have been investigated in the present study. This experimental study is aimed at better understanding the complex fluid dynamic interactions occurring in the near-wake due to base bleed and is motivated by the lack of detailed velocity and turbulence data in this flowfield. The experimental techniques used include static pressure measurements, schlieren and shadowgraph photography, and two-component laser Doppler velocimetry (LDV). The comprehensive LDV mean velocity and turbulence measurements obtained during this study provide valuable insight into the physics of the base bleed mechanism and constitute a benchmark data set to aid analytical and computational efforts in modeling and predicting supersonic base flows.Static pressure measurements show that with increasing bleed flow rate, the average base pressure increases initially, attains a peak value near an injection parameter of I = 0.0148, and then decreases with further increase in I. The peak base pressure ratio at the optimum bleed condition is 18.5% higher than the blunt base case and 5.7% higher than for a 5 degree boattailed afterbody. Axial LDV traverses show peaks in turbulent kinetic energy along the centerline at the forward and rear stagnation point locations. Centerline measurements also indicate the near-disappearance of the primary recirculation region near the optimum bleed condition. Detailed mean velocity and turbulence data were obtained in the entire near-wake flowfield for three different bleed cases corresponding to low bleed, slightly pre-optimal bleed, and slightly post-optimal bleed conditions. These measurements indicate that the bleed flow provides at least some of the fluid required for shear layer entrainment and shields the base annulus from the outer shear layer and the primary recirculation region, leading to an increase in base pressure. There is an overall reduction in turbulence levels throughout the base bleed flowfields relative to the near-wake flowfields of blunt-based and boattailed afterbodies. With increasing bleed, the formation of a strong bleed jet shear layer and secondary recirculation region near the base annulus offsets the benefits of base bleed, leading to a drop in the base pressure. At all bleed conditions, the normal stress distribution is highly anisotropic with the axial component dominating the near-wake turbulence field. The net benefits of base bleed are maximized at the optimum bleed condition, which corresponds to the highest base pressure, the disappearance of the primary recirculation region, and the lowest turbulence and entrainment levels in the near-wake flowfield.Made available in DSpace on 2011-05-07T12:26:18Z (GMT).

An Interactive Dialogue for the Creation, Maintenance and Querying of a Data Base Representative of the Anatomy of an Administrative System
No full textTitle: An Interactive Dialogue for the Creation, Maintenance and Querying of a Data Base Representative of the Anatomy of an Administrative System, Author: Pratima Mathur, Location: ThodeThe logical structure of a database is given, and is
representative of the anatomy of an administrative system,
and of the personnel organization by which it is operated.
This project will adopt an appropriate host computer,
terminal, and physical representation of the database, for
the main purpose of developing a user-terminal dialogue by
which the database can be created and maintained. The
dialogue should be as easy and flexible to use by an audit
analyst as is possible, while at the same time imposing a
systematic and disciplined approach to the task.ThesisMaster of Science (MS
Uncovering a novel role for FXR-SHP axis in liver physiology, diseases and beyond
No full textLiver performs a multitude of functions ranging from detoxification, metabolism and digestion. To execute these tasks, one of the mechanisms that the liver utilizes is nuclear receptor signaling, which in turn can transcriptionally regulate gene networks. My doctoral thesis focuses on studying the role of two nuclear receptors, FXR and SHP in maintaining liver function. Farnesoid X Receptor (FXR) and Small Heterodimer Partner (SHP) are well-known regulators of glucose, fat and bile acid homeostasis. Here, I uncover novel roles for FXR-SHP axis not only in the liver but also in extrahepatic organs, like heart. In Chapter 2, I discuss how hepatic loss of FXR and SHP results in increased glycosylation of liver proteins and structural defects in Golgi apparatus, and ultimately liver cancer. Chapter 3 focuses on comprehending how FXR-SHP ablation results in increased drug metabolic capacity of the liver. Finally, chapter 4 discusses how liver dysfunction, caused by loss of FXR and SHP, can induce metabolic and functional defects in heart. Taken together, these projects will help understand some of the FXR and SHP transcriptional networks under different physiological and pathological contexts and may open avenues for pharmacological manipulation to treat various diseases.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-08-01The student, Bhoomika Mathur, accepted the attached license on 2019-07-04 at 01:18.The student, Bhoomika Mathur, submitted this Dissertation for approval on 2019-07-04 at 01:31.This Dissertation was approved for publication on 2019-07-09 at 15:41.DSpace SAF Submission Ingestion Package generated from Vireo submission #14170 on 2019-11-26 at 13:04:27Made available in DSpace on 2019-11-26T20:49:21Z (GMT).
