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:

Calcium and vitamin D in post menopausal women
No full textCalcium and Vitamin D are widely used therapies for Osteoporosis. Vitamin D is not a vitamin in true sense since it is produced in response to the action of sunlight on skin. Vitamin D has multiple roles in the body, not all of them well-understood. Vitamin D supplementation must be considered a form of hormone replacement therapy. Therefore it raises all the questions about efficacy, dose, and side effects. The Efficacy of use of Calcium and Vitamin D in all post menopausal women in terms of the prevention of fracture is uncertain. The Annual worldwide sales of these supplements have been several billion dollars. The variation of the results from various studies of Calcium and Vitamin D supplementation in elderly women suggest that benefit of calcium plus vitamin D on bone mineral density or the risk of fracture is small and may vary from group to group and baseline Vitamin D status. Women taking supplemental vitamin D and calcium have a statistically increased incidence of renal stones, according to evidence from the Women′s Health Initiative. Studies have shown association between calcium use and increased risk for cardiovascular disease. In a recent review of evidence from 6 randomized trials evaluating the use of vitamin D and calcium to prevent fractures in postmenopausal women who are not living in a nursing home or other institution, the United States Preventive Task Force (USPTF) found no evidence of a benefit from supplementation with 400 IU or less of vitamin D3 and 1000 mg or less of calcium. Also in a report from institute of Medicine Committee, there was insufficient evidence, particularly from randomized trials, that vitamin D treatment affected the risk of non skeletal outcomes like risk of cancer, cardiovascular disease, diabetes, infections, autoimmune disease, and other extra skeletal outcomes

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
Abnormal mitral valve apparatus in a case of hypertrophic obstructive cardiomyopathy: Intraoperative transesophageal echocardiography
No full textHypertrophic obstructive cardiomyopathy is a relatively common disorder that signifies asymmetric hypertrophy of interventricular septum causing obstruction of the left ventricular outflow tract (LVOT). However, more recent studies have shown that during ventricular systole, flow against an abnormal mitral valve apparatus results in drag forces on the part of the leaflets. The mitral leaflet is pushed into the LVOT to obstruct it. We present a case where intraoperative transesophageal echocardiography played a crucial role in defining the etiology of LVOT obstruction that subsequently helped in deciding the surgical plan
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.
Drug-induced bone disorders: A systematic review
No full textDrug-induced bone disorders are a group of disorders characterized by osteomalacia or osteoporosis, with the common denominator being the iatrogenic nature of the disease. Drug-induced bone disorders are either due to the drug directly effecting the bone microarchitecture (osteoblastic or osteoclastic activity) or indirectly by interfering with Vitamin D metabolism, Vitamin D/calcium absorption, and excess calcium loss or due to altered hormone states which promote bone loss (hypogonadism, hyperthyroidism, somatostatin excess states, insulin deficiency, increased systemic inflammation, and oxidative stress). References for this review were identified through searches of PubMed, Medline, and Embase for articles published until July 2019 using the terms “drug induced bone disorders” (MeSH Terms) AND “osteoporosis” (All Fields) OR “osteomalacia” (All Fields). Anti-epileptics, proton pump inhibitors, glucocorticoids, immunosuppressants (calcineurin inhibitors), anticoagulants, glitazones, SGLT2 inhibitors, somatostatin analogs, anticancer medications, and protein kinase inhibitors are some of the commonly used medications associated with bone mineral loss. An increased awareness, minimizing the use of these medications in patients at increased risk of fractures, keeping dosage and duration of therapy to the lowest, ensuring Vitamin D and calcium adequacy either through diet or supplements, and prophylactic use of bisphosphonates (where indicated) can play a major role in preventing morbidity associated with drug-induced bone disorders
Pathways to Social Transformation: Delhi and the Human Right to Housing
No full textabstract: The objective of this study was to better understand promising pathways to realizing human rights norms in the context of rapidly developing cities, and the role that the courts play in this process. Scholars have already started to ask these larger questions of social transformation; however, there continues to be a need for further research since the answers are vast and context-dependent. In order to contribute to these larger conversations, this project examined a key social right in Delhi \u2014 the right to housing. This study relied on interviews with key actors in Delhi's housing sector as well as a review of housing rights cases in the Delhi High Court in order to understand what mechanisms various actors utilize in the context of Delhi to realize the human right to housing on the ground. These two types of data were compared and contrasted to past research on human rights scholarship, law and social literature, and studies on urbanization. Two frameworks from these bodies of knowledge, the MAPs framework developed by Haglund and Aggarwal (2011) and the triangular framework created by Gauri and Brinks (2008), were utilized in particular to analyze interview and court data. Overall, this study found that the courts in India are advocates for housing rights, but that their advocacy is often limited, cautious, and influenced by a pattern of bias against populations without legal title to land. This study also found that communities and their allies are often more successful in realizing the right to housing when they combine litigation with other non-legal social change mechanisms. Consequently, it appears that the role of the courts in realizing ESR in Delhi is both complicated and limited, which means that pathways toward ESR realization are more promising when they incorporate non-legal mechanisms alongside court action
