    In Ayurveda there is a description of 3 Aushadhi : 1. Daivavyapasraya Chikitsa [taking refuge of your Aatma (Soul)], 2. Yuktivyapasraya Chikitsa (taking refuge of device which is considered the fastest way to heal), 3. Sattavajaya Chikitsa (Purity of Thoughts). Here the Mantras are the sacred words having spiritual potency. Mantras are not merely sounds but thoughts which establish a connection between Divine and You. Later comes the sound of that Mantra and its impact is also affected if not done with full attention. Mantra instill confidence, improve concentration and Aatma (soul) therapy is the medicine of the future, soul as a creator of mind & body wave of consciousness protects us from several diseases and reforms the future. Aims & Objective: The aim of the present study was to know the effect of the beej mantra meditation on the student’s BP, Pulse, spo2, Weight and pulse rate. Methods: Manual and electronic search was done on Mantra Chikitsa, Beej Mantra in Charak Samhita, Susruta Samhita and Astanga Hridaya. Then 48 PEC Chandigarh Ist Yr students practised Beej Mantra meditation technique through a one hour lecture. Pre and post meditation measurements were recorded and analysed. Results: Significant number of students reported to be more attentive, comfortable, relaxed and had better memory and had significant reduction in mean pulse rate, Weight, BP. Students expressed a feeling of relaxation and of having a fun filled learning atmosphere after meditation. Conclusion: This simple and easy technique of Beej Mantra meditation could be adopted to enhance Stress reduction in students

    Development and evaluation of a novel method for in-situ medical image display

    Three-dimensional (3D) medical imaging, including computed tomography (CT) and magnetic resonance (MR), and other modalities, has become a standard of care for diagnosis of disease and guidance of interventional procedures. As the technology to acquire larger, more magnificent, and more informative medical images advances, so too must the technology to display, interact with, and interpret these data.This dissertation concerns the development and evaluation of a novel method for interaction with 3D medical images called "grab-a-slice," which is a movable, tracked stereo display. It is the latest in a series of displays developed in our laboratory that we describe as in-situ, meaning that the displayed image is embedded in a physical 3D coordinate system. As the display is moved through space, a continuously updated tomographic slice of a 3D medical image is shown on the screen, corresponding to the position and orientation of the display. The act of manipulating the display through a "virtual patient" preserves the perception of 3D anatomic relationships in a way that is not possible with conventional, fixed displays. The further addition of stereo display capabilities permits augmentation of the tomographic image data with out-of-plane structures using 3D graphical methods.In this dissertation we describe the research and clinical motivations for such a device. We describe the technical development of grab-a-slice as well as psychophysical experiments to evaluate the hypothesized perceptual and cognitive benefits. We speculate on the advantages and limitations of the grab-a-slice display and propose future directions for its use in psychophysical research, clinical settings, and image analysis

    Advanced Magnetic Resonance Imaging in Glioblastoma: A Review

    Get PDF
    INTRODUCTION In 2017, it is estimated that 26,070 patients will be diagnosed with a malignant primary brain tumor in the United States, with more than half having the diagnosis of glioblas- toma (GBM).1 Magnetic resonance imaging (MRI) is a widely utilized examination in the diagnosis and post-treatment management of patients with glioblastoma; standard modalities available from any clinical MRI scanner, including T1, T2, T2-FLAIR, and T1-contrast-enhanced (T1CE) sequences, provide critical clinical information. In the last decade, advanced imaging modalities are increasingly utilized to further charac- terize glioblastomas. These include multi-parametric MRI sequences, such as dynamic contrast enhancement (DCE), dynamic susceptibility contrast (DSC), diffusion tensor imaging (DTI), functional imaging, and spectroscopy (MRS), to further characterize glioblastomas, and significant efforts are ongoing to implement these advanced imaging modalities into improved clinical workflows and personalized therapy approaches. A contemporary review of standard and advanced MR imaging in clinical neuro-oncologic practice is presented

    Desmoid tumour: a rare etiology of intestinal obstruction

    Intestinal obstruction is a frequently encountered entity in surgical practice. The signs & symptoms, many a times, are suggestive of the level of obstruction, making the diagnosis of obstruction evident. There are  various causes of intestinal obstruction which diversify to an enormous extent, stamping on the famous  paradigm for the mysterious nature of the abdomen being referred to as the Pandora's Box. In accordance with the above saying, we report a rare case of a desmoid tumour, presenting as intestinal obstruction, which entices us to strongly believe the same.Key words: Intestinal obstruction, pandora´s box, desmoid tumou

    4th International Conference on Open RepositoriesThis presentation was part of the session : DSpace User Group PresentationsDate: 2009-05-21 08:30 AM – 10:00 AMRealizing the importance and magnitude of Institutional Repository and global visibility and further research scope, Indian Institute of Technology Kanpur, India has intensively planned and designed a full fledged IR project started in mid 2005. Considering the various characteristics and strategies we have designed a well defined and distinct roadmap for establishing our IR in two phases. In the first phase we have planned the mass digitization of entire theses collection of Masters and Doctoral Dissertations produced from 1963 spanning one million pages with their complex content. The content management and uploading to the content server with extracted metadata encoded in XML from our existing server by an in-house developed script is being organised effectively ensuring adequate quality checking of these pages. Initially manual submission for theses was in place. Now a provision has been made available to researchers to submit their theses online even without submitting any hardcopy in the library. The second phase is conceived of digitizing scholarly publications other than theses from our academic community. Its coverage is extremely appreciable in number and strategy we are using for our IR. Excellent feature of our system is the depth customization of DSpace at several places incorporating enhanced features. We discovered that default features offered by even the latest version of DSpace are not sufficient and adequate for academic community to establish their IR system in its full functionality so as to deliver the right information to the right user at the time it is needed. After a detailed study and research we have incorporated significant features like workflow, additional browse and search options, cross-collection search, linking to keywords/subject/homepage/citation, total count of items in respect of supervisor/subject/citation. Additionally, login user authentication from central database, IP based access restrictions, embargo and encryption on the bit stream are also provided. Redesigned feedback form has also been provided to improve its scope and functionalities of our system. These are unique features of our IR system and these enhanced features may be useful to any system in identical academic environment using DSpace to power their Institutional Repositories.Indian Institute of Technology Kanpur, Indi

    Thermoelasticity of Fe2+-bearing bridgmanite

    We present LDA+U calculations of high temperature elastic properties of bridgmanite with composition (Mg(1−x)_{(1-x)}Fex2+_{x}^{2+})SiO3_3 for 0≤x≤0.1250\le{x}\le0.125. Results of elastic moduli and acoustic velocities for the Mg-end member (x=0) agree very well with the latest high pressure and high temperature experimental measurements. In the iron-bearing system, we focus particularly on the change in thermoelastic parameters across the state change that occurs in ferrous iron above ∼\sim30 GPa, often attributed to a high-spin (HS) to intermediate spin (IS) crossover but explained by first principles calculations as a lateral displacement of substitutional iron in the perovskite cage. We show that the measured effect of this change on the equation of state of this system can be explained by the lateral displacement of substitutional iron, not by the HS to IS crossover. The calculated elastic properties of (Mg0.875_{0.875}Fe0.1252+_{0.125}^{2+})SiO3_3 along an adiabatic mantle geotherm, somewhat overestimate longitudinal velocities but produce densities and shear velocities quite consistent with Preliminary Reference Earth Model data throughout most of the lower mantle.Comment: Accepted for Geophysical Research Letters (DOI: 10.1002/2014GL062888

    Quantum-enhanced super-sensitivity of Mach-Zehnder interferometer using squeezed Kerr state

    Full text link
    We study the phase super-sensitivity of a Mach-Zehnder interferometer (MZI) with the squeezed Kerr and coherent states as the inputs. We discuss the lower bound in phase sensitivity by considering the quantum Fisher information (QFI) and corresponding quantum Cramer-Rao bound (QCRB). With the help of single intensity detection (SID), intensity difference detection (IDD) and homodyne detection (HD) schemes, we find that our scheme gives better sensitivity in both the lossless as well as in lossy conditions as compared to the combination of well-known results of inputs as coherent plus vacuum, coherent plus squeezed vacuum and double coherent state as the inputs. Because of the possibility of generation of squeezed Kerr state (SKS) with the present available quantum optical techniques, we expect that SKS may be an alternative nonclassical resource for the improvement in the phase super-sensitivity of the MZI under realistic scenario.Comment: Comments are welcome
