Non-linear behavior of ring-down time in cavity ring-down spectroscopy with tapered fibers
No full textThe effect of surrounding refractive index (n2) on ring-down time (τ) is studied in conventional and amplified cavity ring-down spectroscopy with tapered fibers. Simulation and experimental results indicate that τ varies as rational function of n2
Women’s Bodies as a Site of Cultural Inscriptions in Deepa Mehta’s Fire
No full textDeepa Mehta, Indo-Canadian director’s Fire was released in 1996. The film is the first among her trilogy. It is influential because of her representation of a same-sex relationship in a traditional Indian society of that period of time. This research paper investigates how women’s bodies function as sites of cultural inscriptions in Fire. Fire retains patriarchal ideologies, socio-religious norms, and heteronormative anticipations that frame women’s understandings and bodies. Research questions in this paper are: what kinds of inscriptions are imposed on women’s bodies in Fire, how these inscriptions are enforced and maintained and how Fire contests and subverts these inscriptions? The paper employs qualitative research approach, utilizing textual and filmic analysis. Deepa Mehta’s Fire is the primary text. Feminist theory, postcolonial studies, and Michel Foucault’s discourse on power and the body are the major lenses used to analyze the film Fire. Feminist theories, cultural theory, and scholarly analyses of Fire comprise the secondary source of this paper. This study is based on feminist theory, specifically Judith Butler’s theory of gender performativity and Michel Foucault’s philosophies on disciplining of the body. Furthermore, postcolonial feminist critiques postulate comprehensions into the juncture of gender, culture, and power structures in Fire. Deepa Mehta’s Fire functions as an influential criticism of patriarchal cultural inscriptions on women’s bodies. By foregrounding female longings and resistance, the film encounters prevailing chronicles that standardize women’s identities. It contributes to feminist and postcolonial discourses by emphasizing how cultural inscriptions function and how they can be subverted.

Fiber-Based Cavity Ring-Down Technique for Refractive Index Sensing at 1953 nm Using Tapered Fibers
No full textConventional and amplified fiber-based cavity ring-down techniques (CRDT) are demonstrated for the first time in the 2-m wavelength region. The evanescent field in tapered fibers, used as an intra-cavity element, is utilized to perform refractive index (RI) measurement. These longer wavelengths have larger mode field diameter. This results in larger value of the evanescent field and higher sensitivity, confirmed by the numerical simulations. The effect of tapered fiber diameter is investigated both numerically and experimentally. It is found that smaller diameters provide higher sensitivity. The best detection limit achieved experimentally is 4.8 10-5 RIU at RI of 1.31 with a tapered fiber of length 4 mm and a diameter of 5.35 μm, in conjunction with amplified CRDT. The detection limit can be further improved when the cavity is designed with components and fiber that are optimized for minimal loss at these wavelengths

Assessment of static and dynamic balance in overweight and obese children with and without flatfoot: A cross-sectional study
No full textBackground: Childhood obesity and overweight have been referred by health organization as serious epidemic and global problems that are on the rise. The consequence of being overweight in children is the greater impairment of mobility which may result in several orthopedic conditions. The foot dimensions of overweight children and obese children will be larger than those of normal weight children. Balance is defined as an ability to maintain the center of mass over base of support. Balance as a sensorimotor ability helps in maintaining static and dynamic equilibrium. The presence of abnormalities in the foot structures may affect the displacement of the body, function in static, and dynamic position.
Methodology: This was a cross-sectional study done in overweight and obese children with and without flatfoot. A total of 1165 children were screened out of which 87 were found to have obesity between the age group of 6–12 years from 11 schools. Static balance of children was measured using balance error scoring system (BESS) and stork balance stand test (SBST), and dynamic balance was measured using four square step test (FSST) and modified bass test of dynamic balance (MBTDB).
Results: The static balance was significantly affected in obese children with and without flatfoot and also in overweight children with flatfoot whereas dynamic balance was affected in obese children with flatfoot. BESS (P = 0.001), MBTDB (P = 0.006), and FSST (P = 0.001) were statistically significant. There was no significant difference found on SBST (P = 0.0657) when compared within and between the groups.
Conclusion: Obese children with flatfoot had poor static and dynamic balance compared to overweight children with flatfoot when it was tested on BESS and MBTDB and FSST
Micro-raman spectroscopy of caries lesion formation in dental enamel
No full textCaries lesions form by a complex process of chemical interactions between dental enamel and its environment. They can cause cavities and pain, and are expensive to fix. Lesions form by slow demineralization over many months, even years. It is hard to characterize in vivo as a result of environmental factors and remineralization by ions in the oral cavity. In this thesis the process of demineralization was carried out in vitro and micro-Raman spectroscopy used to investigate and characterize the lesion's chemistry. Demineralization occurs by diffusion across the depth of the lesion of mineral ions via interstitial spaces in the dental enamel. Hydroxyl ions are initially lost by acidic attack, which increases the interstitial space. The demineralization is retarded by diffusion processes in the opposite direction, and a balance in the charges of the ions must be maintained. Having multiple ions diffusing simultaneously is termed &amp;amp;#08220;coupled diffusion&amp;amp;#08221;. A subsurface highly demineralized region is formed, but this can be remineralized.
Micro-Raman spectroscopy is a powerful tool for studying material composition by exciting chemical bonds in the sample. Using micro-Raman to characterize the chemical composition of lesions may help in developing preventative measures to stop their formation. Raman (λ=785 nm) was used to characterize lesions grown over 5, 7, 9, 11 and 14 days. The amide I peak at ~1605 cm-1, which has not been observed previously, was seen in the maturing lesions. The extreme demineralization in these lesions enables the organic peaks to be seen rather than the normally stronger mineral peaks. Analysis of crystallinity shows that there is always a reduction in mineral content with distance below the enamel surface, but this becomes magnified as the lesion matures. Type B carbonate substitution for phosphate ions can also be examined with Raman. Correcting for crystallinity shows that both carbonate and phosphate ions are lost at the same rate during demineralization.
In summary, micro-Raman is an effective and relatively easy tool to use in lesion characterization. It also has the advantage that it can be used to identify changes in both the mineral and protein phases of enamel.M.S.Includes bibliographical references (p. 53-55)
Out of Thin Air: Evaluating the Legality of the Clean Power Plan under the Equal Sovereignty Principle
No full textThe Clean Power Plan requires states to meet specific carbon emissions targets based on the amount of pollution emitted from in-state power plants. The rule marks the most aggressive action taken by the United States to combat climate change. The rule, however, is currently facing a litany of legal challenges. In addition to the questionable legal authority under which the regulation was promulgated, the regulation may be constitutionally problematic. This paper examines whether the rule violates the Equal Sovereignty Principle as articulated in the Supreme Court\u27s blockbuster ruling in Shelby County v. Holder because it exempts Alaska and Hawaii without sufficient justification, and because of its disproportionate burden on coal states. This paper argues that the Equal Sovereignty Principle indeed applies to the Clean Power Plan, and that the rule violates the doctrine of Equal Sovereignty because it exempts Alaska and Hawaii. The paper also argues that the principle\u27s application in this context may actually result in wider application of the Clean Power Rule and further environmentalists\u27 objectives of ensuring that the burden of mitigating climate change is shared among the states
