India's National Population Policy (2000): An Evaluation
No full textprofessional paper for the fulfillment of the Masters of Public Policy degreeThis paper examines the quality of India’s family planning practice under the National Population Policy (2000) or NPP-2000. The intent of NPP-2000 is to eliminate unmet contraceptive needs by providing high quality reproductive healthcare. In particular, the NPP-2000 aims to address flaws in healthcare infrastructure and to achieve a total fertility rate of 2.1 births per woman by 2010. Unfortunately, the implementation difficulties of past years persist in the era of NPP-2000. Indian families are subject to poorly-trained healthcare personnel and insufficient medical supplies, among other setbacks. Using interviews with family planning professionals and data from quantitative
and qualitative studies, the following analysis exposes widespread variation in the quality of family planning practice. Additionally, the author proposes strategies to address unmet contraceptive needs in northern states and among disadvantaged populations.Agrawal, Sandhya. (2009).

Effect of Chitosan on Okra (Abelmoschus esculentus (L.) Moench) Seed Germination
No full textPresent paper deals with the effect of chitosan at different concentration on seed germination of okra. It was revealed that chitosan at 0.03%, 0.12%,0.3% and 0.6% concentration induced seed germination in okra while at 0,03% there was maximum seed germination percentage as compare to other treatments. 1Department of Botany, Dr. Babasaheb Ambedkar Marathwada University, Aurangabad- 431 004 (MS), India; 2Department of Chemistry, Dr. Babasaheb Ambedkar Marathwada University, Aurangabad- 431 004 (MS), India; 3Department of Botany, University of Pune, Pune -411 007 (MS), India.* Corresponding Author, Email: [email protected] Cite This Article As: Sandhya Jaybhay, Asha Chate and Avinash B.

The authors regret that the legends to Fig. 3 (C, D, and I) and Fig. 4 (B, C, and E) did not originally specify that the values shown are adjusted P values. In addition, the colors used in the bar graph in Fig. 4 B were not correct nor defined. The corrected legends, with new text underlined, and corrected Fig. 4 are shown here.

Atmospheric neutrinos: Status and prospects
No full textAbstractWe present an overview of the current status of neutrino oscillation studies at atmospheric neutrino experiments. While the current data gives some tantalising hints regarding the neutrino mass hierarchy, octant of θ23 and δCP, the hints are not statistically significant. We summarise the sensitivity to these sub-dominant three-generation effects from the next-generation proposed atmospheric neutrino experiments. We next present the prospects of new physics searches such as non-standard interactions, sterile neutrinos and CPT violation studies at these experiments
How it feels: The value and application of physical sensation in XR: Explore Somatosensory experience’s possibility in future XR trends
No full textThis research advocates for exploring the somatosensory system and its incorporation within XR systems, particularly in spatial recognition. This paradigm shift could introduce novel methodologies in XR design that perceive the body as a recipient of sensory stimuli and as an active participant in sensory perception. This could redefine our understanding of somatosensory in XR and contribute to a more holistic approach to multisensory design. Additionally, this study aims to examine the deployment of XR in the evaluation of aircraft interior design. The successful integration of XR technologies could potentially revolutionize the design process by presenting a more immersive and authentic user testing environment. In light of the present deficiency in precise spatial recognition within XR applications, this research could offer fresh insights into optimizing XR use in design, thereby improving spatial perception accuracy and enhancing ergonomics and user experience in real-world applications, such as aircraft interior design.Integrated Product Desig

No full textPneumatically-actuated acoustic metamaterials based on helmholtz resonators
No full textMetamaterials are periodic structures which offer physical properties not found in nature. Particularly, acoustic metamaterials can manipulate sound and elastic waves both spatially and spectrally in unpreceded ways. Acoustic metamaterials can generate arbitrary acoustic bandgaps by scattering sound waves, which is a superior property for insulation properties. In this study, one dimension of the resonators (depth of cavity) was altered by means of a pneumatic actuation system. To this end, metamaterial slabs were additively manufactured and connected to a proportional pressure control unit. The noise reduction performance of active acoustic metamaterials in closed-and open-space configurations was measured in different control conditions. The pneumatic actuation system was used to vary the pressure behind pistons inside each cell of the metamaterial, and as a result to vary the cavity depth of each unit cell. Two pressures were considered, P = 0.05 bar, which led to higher depth of the cavities, and P = 0.15 bar, which resulted in lower depth of cavities. The results showed that by changing the pressure from P = 0.05 (high cavity depth) to P = 0.15 (low cavity depth), the acoustic bandgap can be shifted from a frequency band of 150-350 Hz to a frequency band of 300-600 Hz. The pneumatically-actuated acoustical metamaterial gave a peak attenuation of 20 dB (at 500 Hz) in the closed system and 15 dB (at 500 Hz) in the open system. A step forward would be to tune different unit cells of the metamaterial with different pressure levels (and therefore different cavity depths) in order to target a broader range of frequencies.Novel Aerospace Material
Active acoustic metamaterial based on Helmholtz resonators to absorb broadband low frequency noise
No full textMetamaterials are a new class of materials that have properties that cannot be found in nature. Though these artificially engineered structures have not been prominently used in many applications, they have been theoretically studied to have a variety of applications in many sectors. Acoustic metamaterials have the capability of manipulating sound waves in order to achieve the required unique properties.The aim of the project is to design an active acoustic metamaterial consisting of an array of Helmholtz resonators to assist in reduction of noise levels in aerospace applications using the method of 3D printing.This project presents an active Helmholtz resonator based design that can attenuate a broadband range of targeted frequencies in the low-frequency regime. To this end, a passive metamaterial consisting of an array of Helmholtz resonator unit cells, with a single varying design variable, is designed and tested to establish the effectiveness and region of performance. The selected design variable for change is identified through the frequency response for each parameter of the Helmholtz resonance equation, to achieve a broadband frequency range of the metamaterial. An active model of this design is then fabricated and tested. Two actuation mechanisms are presented for this design. The resulting acoustic systems are capable of providing an attenuation of up to 20 dB, for an open system, and up to 35 dB, for a closed system, at frequencies between 150 Hz and 500 Hz. Unlike most other studies conducted, this active acoustic design is capable of attenuating isolated frequencies as well as multiple frequencies simultaneously. The added control that is achieved through the incorporation of the electric linear motor based actuation allows for the advantage of accurate frequency targeting along with the base attenuation levels of the passive resonant acoustic metamaterial.Aerospace Engineerin
