Effect of firm-specific and macroeconomic conditions on corporate cash holdings: evidence from FMCG companies in India / Reeti Gaur and Rajinder Kaur.
Get PDFThis paper attempts to find out the effects of firm-specific and macroeconomic variables on corporate cash holdings. Panel data regression analysis was applied on the selected FMCG companies in India for the years2001-02 to 2016-17. The analysis showed that FMCG firms in India prefer keeping huge amounts of cash reserves and one of the preferred sources of cash holdings is cash flow. However, large scale and highly levered firms do not have large cash holdings. On the other hand, among the macroeconomic variables economic growth and bank lending rate play a significant role while amaking cash holding decisions. The paper has tried to fill the gap in previous literature that often ignore the role of macroeconomic elements in cash holding decisions
Structural, optical and thermal properties of glass and anti-glass phases in strontium tellurite and borotellurite systems doped with europium
No full textGlass sample of the composition: 10SrO-90TeO2 was prepared by melt-quenching technique and found to contain triangular, rectangular, and spherical shaped micro-inclusions of the average size ∼803 μm in the glassy matrix. The inclusions grow to an average size of ∼1347 μm and assume flower-like morphology upon adding 1 mol% Eu2O3 in the 10SrO-90TeO2 sample. X-ray diffraction studies showed that the micro-inclusions exhibit sharp peaks, but their Raman spectra have broad phonon bands that are indistinguishable or very similar to that of the glassy matrix phase. The addition of 10 mol% B2O3 in the samples inhibits the growth of inclusions of anti-glass phases and forms purely amorphous samples. B2O3 significantly enhances the photoluminescence properties of Eu3+ doped samples. Furthermore, B2O3 converts the four-fold co-ordinated Te-O structural units into three-fold co-ordinated Te-O units.Atul Khanna thanks the UGC-DAE Consortium for Scientific Research, Indore and Mumbai Centers, India for research grants.

Ubiquitous interactive displays: magical experiences beyond the screen
Get PDFUbiquitous Interactive Displays are interfaces that extend interaction beyond traditional flat screens. This thesis presents a series of proof-of-concept systems exploring three interactive displays: the first part of this thesis explores interactive projective displays, where the use of projected light transforms and enhances physical objects in our environment. The second part of this thesis explores gestural displays, where traditional mobile devices such as our smartphones are equipped with depth sensors to enable input and output around a device. Finally, I introduce a new tactile display that imbues our physical spaces with a sense of touch in mid air without requiring the user to wear a physical device. These systems explore a future where interfaces are inherently everywhere, connecting our physical objects and spaces together through visual, gestural and tactile displays. I aim to demonstrate new technical innovations as well as compelling interactions with one ore more users and their physical environment. These new interactive displays enable novel experiences beyond flat screens that blurs the line between the physical and virtual world.Submission published under a 24 month embargo labeled 'U of I only', the embargo will last until 2017-05-01The student, Rajinder Sodhi, accepted the attached license on 2015-03-30 at 21:37.The student, Rajinder Sodhi, submitted this Dissertation for approval on 2015-03-30 at 21:48.This Dissertation was approved for publication on 2015-04-01 at 16:12.DSpace SAF Submission Ingestion Package generated from Vireo submission #7777 on 2015-07-22 at 14:17:11Made available in DSpace on 2015-07-22T22:33:04Z (GMT).

Asian Modernity: Cricket in Princely States – Case Example of Dhruve Pandove Cricket Stadium cum Gymkhana Club Patiala, Punjab
Get PDFThe paper bringing about the certain changes, which were implies in Asian countries during the 18th century, when most part of these countries comes under British impact. Considering India only, the changes were not focusing only on the architectural style, but it was the entire process to structure the society in a better way. Britishers, by nature were very fond of recreation, entertainment, luxury in their life. Sports was one of the medium of their entertainment through which they interact among high societies. When cricket was introduced in India by Britishers, it was become most popular game among all the states. Maharajas of princely states were always try to copy the British life style, so they adopted cricket also with full obsession. Maharajas of Patiala, princely state Punjab along with their royal families, were in passionate lead to support Cricket as major sport (Majumdar, B. 2008). They had taken cricket to utmost priority and formed their own cricket grounds in Chail and Patiala. Maharaja Rajinder Singh, constructed a cricket ground and pavilion in 1890 in Patiala named as ‘Dhruve Pandove Stadium’ from where he initiated the cricket patronage (Sarkar, A. 2016). The pavilion is constructed in colonial style, which has given India a number of leading crickets, is still intact in good and working condition.

Diasporic audiences and non-resident media: The case of Indian films
Get PDFThis article seeks to demonstrate how various overlapping claims made by politicians, film producers and academics regarding diasporic audiences have constructed a particular model of cultural transmission emerging from a globalised mediasphere. Taking the case of popular Indian films and their global circulation, this article goes on to challenge the dominant ethnocultural explanations of popular culture and its circulation. Following a consideration of the empirical and epistemological faultlines arising from that paradigm, it is claimed that the tidy equation of media dispersal with migrant ethnicities is not only problematic in this specific case, but also that it provides for misleading conclusions about the relationship between cultural identity and media consumption. On reflection, it is argued that the epistemological foundation of global audience studies must provide for a greater recognition of the subjective and demographic diversity of audiences as well as the inherent hybridity and multiplication of media sources in everyday experience
Design and Analysis of Evanescent-Wave Based D-Shaped Fiber-Optic Photonic Sensing Device for Pathogen Detection
No full textOptical sensors have emerged as transformative tools in sensing technology, offering good detection sensitivity and adaptability across diverse applications. The integration of plasmonic elements with optical waveguides has unlocked new frontiers in high-throughput optical sensing, leveraging properties such as absorbance, transmittance, and reflectance. While conventional spectroscopic techniques often face challenges like limited applicable sensitivity and impracticality for field applications, evanescent wave-based optical sensors provide a compelling alternative. The efficacy of evanescent wave absorption is governed by factors including the analyte's extinction coefficient, concentration, interaction area, wavelength of light, and the refractive indices of the medium and waveguide. By coupling evanescent wave absorption with the localized surface plasmon resonance (LSPR) effect of noble metal nanoparticles, researchers are developing cost-effective, user-friendly, and highly sensitive sensors tailored for field deployment.
This study focuses on fiber optics-based evanescent wave sensors (FOS), emphasizing D-shaped optical fibers. This geometry enhances interaction between the evanescent field and analytes, enabling deeper field penetration, minimizing noise, and optimizing the signal-to-noise ratio. Gold nanoparticles (AuNPs), chosen for their biocompatibility, low toxicity, and ease of functionalization, play a pivotal role in advancing sensor performance. By leveraging these nanoparticles' size- and shape-dependent optical properties, this research work demonstrates the development of a robust LSPR sensing platform for agricultural applications.
The proposed sensor integrates a D-shaped fiber optic geometry functionalized with AuNPs using a cost-effective silanization-based nanoparticle immobilization process. This method achieves uniform nanoparticle distribution, ensuring enhanced plasmonic interactions and reproducible sensor performance. A systematic investigation of nanoparticle distribution and binding dynamics confirmed an optimized LSPR response at 540 nm, demonstrating high sensitivity to refractive index changes. For bare probes, the refractive index sensitivity was evaluated using sucrose solutions, yielding a linear correlation between sensor area and sensitivity. The functionalization with amine groups and subsequent AuNP immobilization further improved detection sensitivity, achieving a limit of detection (LOD) of 0.118 ± 0.047 × 10⁻³ RIU with a sensitivity of 1.025 ΔA/Δn.
The sensor's biosensing capabilities were validated using immunoglobulin antibody (HIgG) detection, achieving an LOD of 0.6 μg/mL through antigen-antibody conjugation. Further, extended its application to plant pathogen detection, the sensor was adapted for Begomovirus DNA sensing by immobilizing complementary DNA (cDNA) probes on the AuNP-functionalized surface.

The dynamic LSPR absorption response confirmed successful hybridization with single-stranded viral DNA (ssDNA) extracted from Tomato Leaf Curl New Delhi Virus-infected leaves. This sensor achieved an LOD of 85 ± 5 ng/μL, demonstrating comparable sensitivity and specificity with other standard detection such as polymerase chain reaction and enzyme-linked immunosorbent assay.
This research work demonstrated the versatility and potential of D-shaped fiber optic LSPR sensors for real-time, on-site detection of plant pathogens. By optimizing probe geometry and functionalization techniques, the developed sensor achieves remarkable sensitivity and selectivity, making it a valuable tool for agricultural disease management. The conceptualized optical sensing platform, based on digital electronic logic states, further enhances the sensor's utility for versatile diagnostic systems. Beyond agriculture, this technology shows promise for broader applications, including environmental monitoring and healthcare diagnostics.
The findings presented herein offer a robust proof-of-concept for advanced optical sensing technologies, paving the way for scalable and cost-effective solutions to address challenges in agriculture. By redesigning D-shaped fiber arrays and optimizing plasmonic interactions, this research established a benchmark for the development of next-generation optical biosensors for plant pathogen detection. The demonstrated ability to detect various genera of begomo-viruses and the potential for multi-target sensing highlight its profound impact on improving crop yield and disease control strategies, ensuring a significant contribution to the global agricultural production landscape
