How do variations in Urban Heat Islands in space and time influence household water use? The case of Phoenix, Arizona
No full textabstract: This paper explores how urbanization, through its role in the evolution of Urban Heat Island (UHI), affects residential water consumption. Using longitudinal data and drawing on a mesoscale atmospheric model, we examine how variations in surface temperature at the census tract level have affected water use in single family residences in Phoenix, Arizona. Results show that each Fahrenheit rise in nighttime temperature increases water consumption by 1.4%. This temperature effect is found to vary significantly with lot size and pool size. The study provides insights into the links between urban form and water use, through the dynamics of UHI.Corresponding Author:

Biodegradation of atrazine by atrazine chlorohydrolase: characterization of mutant enzyme and immobilization system for water purification.
No full textUniversity of Minnesota M.S. thesis. January 2012. Major:Biochemistry, Molecular Biology and Biophysics. Advisors: Lawrence P. Wackett & Ping Wang. 1 computer file (PDF); viii, 85 pages.Atrazine is the most widely used herbicide by corn and sorghum growers. Atrazine
chlorohydrolase (AtzA) dechlorinates atrazine, producing non-toxic and non-phytotoxic
hydroxyatrazine. In this study, we report the cloning and initial experiments for partial
characterization of mutant AtzA (Colin Scott, Colin J. Jackson, Chris W. Coppin, et al.
2009. Catalytic Improvement and Evolution of Atrazine Chlorohydrolase. Appl. Environ.
Microbiol. 75(7):2184-2191). A plasmid vector was designed for ease of purification of
the enzyme with the help of a his-tag and to ensure high expression of soluble protein in
recombinant E.coli. The specific activity and substrate specificity of the purified mutant
AtzA was then compared to the wild type enzyme. It was observed from these initial
studies that the mutant enzyme had somewhat similar characteristics to the wild type
enzyme.
Further, the current study also describes immobilization recombinant E. coli cells
expressing the wild type atrazine chlorohydrolase in a silica/polymer porous gel. This
novel recombinant enzyme-based method utilizes both adsorption and degradation to
remove atrazine from water. A combination of silica nanoparticles (Ludox TM40),
alkoxides, and an organic polymer were used to synthesize a porous gel. Gel curing
temperatures of 23°C or 45°C were used to either maintain cell viability or to render the
cells non-viable, respectively. The enzymatic activity of the encapsulated viable and nonviable
cells was high and extremely stable over the time period analyzed. At room
temperature, the encapsulated non-viable cells maintained a specific activity between (0.44 ± 0.06) μmol/g-min and (0.66 ± 0.12) μmol/g-min for up to 4 months, comparing
well with free, viable cells specific activities (0.61 ± 0.04 μmol/g-min). Gels cured at 45°C
had excellent structural rigidity and contained few viable cells, making these gels
potentially compatible with water treatment facility applications.Aggarwal, Amit. (2012).

Kleine-Levine syndrome in an adolescent female and response to modafinil
No full textKleine-Levine Syndrome (KLS) is a disorder characterized by a triad of periodic hypersomnia, hyperphagia, and hypersexuality. KLS, although more common in young males, it has also been seen in females. Treatment options available for its management include mood stabilisers like lithium, stimulants like amphetamines, antidepressants and other options including electroconvulsive therapy. Modafinil is one of the new stimulant medications approved for narcolepsy. Herein, we report a young female with KLS and showing favorable response to modafinil. More data is required to establish the effectiveness of modafinil in this syndrome
Decoding "Public authority" under the RTI act: a comment on Subhash Chandra Aggarwal v. Indian national congress
No full textThe June, 2013 order of the Central Information Commission ("CIC") in Subhash Chandra Aggarwal v. Indian National Congress which brought political parties within the scope of the Right to Information ("RTI") Act, has highlighted some issues regarding the drafting and interpretation of the RTI Act. The CIC held that the six national political parties which were respondents
in the case, have the ingredients that qualify them as "public authorities" within the meaning of section 2(h) of the RTI Act. In this comment the author argues that the reasoning for holding what constitutes substantial financing that makes a body a "public authority" is not clear and the interpretation of the definition of "public authority" is inconsisten
Impact of tariff reduction on exports: A quantitative assessment of Indian exports to US
No full textThis paper quantitatively assesses likely changes in market access opportunities for Indian exports owing to tariff reductions by the USA. The study identifies particular products for India at the ISIC 4-digit level of disaggregation, which could be considered tariff sensitive. Regression analysis of the relationship between MFN tariff rates and India's exports to the US was used to assess in quantitative terms the likely impact of tariff reduction that may be agreed in the Doha Round. This analysis suggests that tariff cuts are not expected to benefit India's exports to the US in a major way. With the full implementation of the Chairman's formula for tariff cuts, increase in India's exports to the US would amount to 1.2 or 0.6 depending on the value of the B coefficient in theChairman's formula. These findings are in all likelihood substantially due to the tariff diversion effect of NAFTA preferences in favour of suppliers in Mexico, which is a competing country in many traditional items. It is expected that reduction of MFN tariff would alleviate the trade diversion effect of the NAFTA.The study has also attempted to decompose changes in India's total exports due to tariff reductions in the US into the competitive and market effects. The analysis suggests that the increase in India's exports would be mainly due to the competitive effect. This leads the author to conclude that it is crucial for India to improve its competitiveness vis-a-vis its competitors in different markets.
