Quality Management System Implementation at KELTEC-A Case Study

The scenario of quality is expanding exponentially. In the present-day world, quality is now in the driver's seat. With this globalisation of industrial products, many problems and opportunities have risen, primarily due to inconsistent standards existing in the market. The International Standards Organisation has tried (and seem to be very successful in doing so) to standardise a minimum level of quality norms. These norms act as the foundation to implements total quality management (TQM). TQM has been identified as a philosophy of interdependent characteristics, such as customer focus, commitment, measurement, systematic support, and continuous improvement. This paper presents a case study on the implementation of ISO 9002: 1994 at Kerala Hitech Industries (KELTEC), with the benefits, hurdles faced, and shortcomings. Upgradation of KELTEC's quality management system to the requirements of ISO 9001: 2000 is currently under progress

Dissecting galactic bulges in space and time I: The importance of early formation scenarios vs. secular evolution

This article has been accepted for publication in Monthly Notices Royal Astronomical Society ©: 2014 The Authors. Published by Oxford University Press on behalf of the Royal Astronomical Society. All rights reservedThe details of bulge formation via collapse, mergers, secular processes or their interplay remain unresolved. To start answering this question and quantify the importance of distinct mechanisms, we mapped a sample of three galactic bulges using data from the integral field spectrograph WiFeS on the ANU's 2.3-m telescope in Siding Spring Observatory. Its highresolution gratings (R ~ 7000) allow us to present a detailed kinematic and stellar population analysis of their inner structures with classical and novel techniques. The comparison of those techniques calls for the necessity of inversion algorithms in order to understand complex substructures and separate populations. We use line-strength indices to derive single stellar population equivalent ages and metallicities. Additionally, we use full spectral fitting methods, here the code STECKMAP, to extract their star formation histories. The high quality of our data allows us to study the 2D distribution of different stellar populations (i.e. young, intermediate and old). We can identify their dominant populations based on these age-discriminated 2D light and mass contribution. In all galactic bulges studied, at least 50 per cent of the stellar mass already existed 12 Gyr ago, more than currently predicted by simulations. A younger component (age between ~1 and ~8 Gyr) is also prominent and its present day distribution seems to be affected much more strongly by morphological structures, especially bars, than the older one. This in-depth analysis of the three bulges supports the notion of increasing complexity in their evolution, likely to be found in numerous bulge structures if studied at this level of detail, which cannot be achieved by mergers alone and require a non-negligible contribution of secular evolutionMKS acknowledges the support of the Instituto de Astrofísica de Canarias via an Astrophysicist Resident fellowship and Ignacio Martín-Navarro, Andra Stroe and Stéphane Courteau for useful discussions.

Resolving the disc–halo degeneracy – I: a look at NGC 628

The decomposition of the rotation curve of galaxies into contribution from the disc and dark halo remains uncertain and depends on the adopted mass-to-light ratio (M/L) of the disc. Given the vertical velocity dispersion of stars and disc scale height, the disc surface mass density and hence the M/L can be estimated. We address a conceptual problem with previous measurements of the scale height and dispersion. When using this method, the dispersion and scale height must refer to the same population of stars. The scale height is obtained from near-infrared (IR) studies of edge-on galaxies and is weighted towards older kinematically hotter stars, whereas the dispersion obtained from integrated light in the optical bands includes stars of all ages. We aim to extract the dispersion for the hotter stars, so that it can then be used with the correct scale height to obtain the disc surface mass density. We use a sample of planetary nebulae (PNe) as dynamical tracers in the face-on galaxy NGC 628. We extract two different dispersions from its velocity histogram – representing the older and younger PNe. We also present complementary stellar absorption spectra in the inner regions of this galaxy and use a direct pixel fitting technique to extract the two components. Our analysis concludes that previous studies, which do not take account of the young disc, underestimate the disc surface mass density by a factor of ∼2. This is sufficient to make a maximal disc for NGC 628 appear like a submaximal disc

Extragalactic Radio Continuum Surveys and the Transformation of Radio Astronomy

Next-generation radio surveys are about to transform radio astronomy by discovering and studying tens of millions of previously unknown radio sources. These surveys will provide new insights to understand the evolution of galaxies, measuring the evolution of the cosmic star formation rate, and rivalling traditional techniques in the measurement of fundamental cosmological parameters. By observing a new volume of observational parameter space, they are also likely to discover unexpected new phenomena. This review traces the evolution of extragalactic radio continuum surveys from the earliest days of radio astronomy to the present, and identifies the challenges that must be overcome to achieve this transformational change.Comment: To be published in Nature Astronomy 18 Sept 201

Resolving the Disc–Halo Degeneracy – II: NGC 6946

The mass-to-light ratio (M/L) is a key parameter in decomposing galactic rotation curves into contributions from the baryonic components and the dark halo of a galaxy. One direct observational method to determine the disc M/L is by calculating the surface mass density of the disc from the stellar vertical velocity dispersion and the scale height of the disc. Usually, the scale height is obtained from near-IR studies of edge-on galaxies and pertains to the older, kinematically hotter stars in the disc, while the vertical velocity dispersion of stars is measured in the optical band and refers to stars of all ages (up to ∼10 Gyr) and velocity dispersions. This mismatch between the scale height and the velocity dispersion can lead to underestimates of the disc surface density and a misleading conclusion of the submaximality of galaxy discs. In this paper, we present the study of the stellar velocity dispersion of the disc galaxy NGC 6946 using integrated star light and individual planetary nebulae as dynamical tracers. We demonstrate the presence of two kinematically distinct populations of tracers that contribute to the total stellar velocity dispersion. Thus, we are able to use the dispersion and the scale height of the same dynamical population to derive the surface mass density of the disc over a radial extent. We find the disc of NGC 6946 to be closer to maximal with the baryonic component contributing most of the radial gravitational field in the inner parts of the galaxy (Vmax(bar) = 0.76(±0.14)Vmax)

GINGIVAL FIBROMATOSIS WITH HEARING LOSS: A JONES SYNDROME CASE REPORT

Introduction: Hereditary Gingival Enlargement (HGF), a rare entity, is also known as familial elephantiasis, elephantiasis gingivae, diffuse fibromatosis. It is a benign, non-haemorrhagic fibrous enlargement of gingival tissue. It is frequently a component feature of many syndromes. Jones syndrome is one such syndrome, characterized by gingival overgrowth and progressive deafness.&#x0D; Case report: A 27-year-old male patient reported to the Department of Oral Medicine and Radiology with the chief complaint of swollen gums for the past 7 years. The patient also complained of bleeding gums on brushing. The medical history stated a concurrent gradual hearing loss 7 years back. An incisional biopsy was done to confirm the fibrous nature of the diagnosis.&#x0D; Conclusion: This reporting is of unique case that remained undiagnosed for almost a decade. It also emphasises the need of a multidisciplinary approach during diagnosis and treatment.</jats:p

Assessment of dental problems faced by adult population during lockdown

People have always coped with their dental issues on their own until they have an exacerbation of the symptoms. During this pandemic, there had people suffering from various dental issues, yet they have either overlooked or coped with these issues on their own. There are cases reported of harmful effects of improper use of home remedies and the hazardous effect of over-the-counter medications. Hence, this survey concentrates on the various dental problems they have faced and how they overcame them during this pandemic. Coping up with dental problems during the pandemic patient’s perspective-a questionnaire study. This questionnaire study was conducted in our department with a total sample size n = 805 with only the residents of Chennai with an open-ended questionnaire containing 21 questions. All the patients who walked into the department were included in the study based on the inclusion criteria such as age above 18 years, willingness to participate, faced any dental issues during the lockdown, there was a time lag between their issue and the treatment and all the answers were digitalised and sent for statistical analysis.</jats:p
