Management of Tracheo Bronchial Foreign Bodies in Children – A Retrospective Study of series of 50 cases

Abstract             This retrospective study of series of 50 cases of inhaled foreign bodies in pediatric patients in one year, deals with which the cases presented and the types of foreign body removed. Diagnostic flexible bronchoscopy aid in the diagnosis of unsuspected foreign body aspiration, or with doubtful history of foreign body aspiration without physical or X-ray signs and can proceed with definitive treatment in the same preparation without delay. Tracheotomy is indicated for foreign body that cannot be removed through glottis. A team work of anesthetist, endoscopist, and assistants are essential to ensure the safety of procedure with no compromise on availability of instruments.  Key words Tracheo Bronchial · Foreign Bodies · Children · Management

Taxonomical Keys for Morphological Identification of Coral-Associated Polychaetes from Great Nicobar Islands

The present study illustrates the insufficient taxonomy records and highlights the use of microscopic diagnostic tool in polychaete taxonomy. It leads to a better understanding of coral-associated polychaete taxonomy in Great Nicobar Islands, India. A total of 24 species under 14 genera, 7 orders, and 11 families were identified, in spite of 3 species of Phyllocidae, 8 species of Nereidae, 5 species of Eunicidae, 2 species of Spionidae, and 1 species of Opheliidae, Sabellariidae, Terebellidae, Polynoidae, Amphinomidae, and Sabellidae. The current status of taxonomic information varies greatly among taxa and among geographic areas within taxa. The problems encountered included nomenclature, diagnoses, and determination of taxonomic relationships. We provide examples of a variety of these problems. Each species has distinct features of the particular families, and taxonomic section to assist the polychaete identification that is necessary to assess the biodiversity and taxonomy at any level. This chapter considers the importance of monitoring biological diversity, current morphological taxonomy of polychaetes and describes the approach developed for protected areas in Great Nicobar Islands

Classical solutions of a model of quark confinement

We find the classical solutions of a model of quark confinement defined by the vanishing of colour currents. Both plane-wave type of solutions extending all over space as well as string-type of solutions confined to restricted regions of space are found

Critical current density of a sample of melt grown Y<SUB>1&#183;2</SUB>Ba<SUB>1&#183;8</SUB>Cu<SUB>2&#183;4</SUB>O<SUB>x</SUB>

Melt grown samples of Y1&#183;2Ba1&#183;8Cu2&#183;4Ox have been prepared and studied for their current carrying capacity. The composition was chosen to include Y2BaCuO5 (211) particles in the YBa2Cu3Ox (123) phase. The critical current density (Jc) of these samples was studied as a function of magnetic field using magnetization technique. The micrographic investigation shows well aligned grains in this material. The magnetic hysteresis measurements were done using a MPMS SQUID magnetometer up to the fields of 5.5 T. The Jc was estimated from the remanent magnetization using Bean model. Isothermal magnetization hysteresis loops at low fields reveal the presence of only one kind of hysteresis loops (corresponding to intragrain magnetizations). This is a valid proof that the weak links are greatly eliminated in these samples prepared by MG process. The Jc behaviour as a function of magnetic field has two components, a rapidly decaying exponential function of field and the other component that predominates at higher fields. This could be explained if we assume that the sample contains two phases of superconductors, one having a low Hc2 becoming normal at fairly medium fields of the order of a few kilogauss will act as pinning centres for the other phase having higher Hc2 and hence higher Jc at high fields

Generation of gluons from quark confinement

We study a model of quark confinement defined by the vanishing of colour currents. The model is shown to be equivalent to quantum chromodynamics and this equivalence is interpreted as due to the compositeness of the colour gluons. The Green's functions of the theory are found to contain nontrivial structure only for colour singlet composites which can be identified with hadrons

Renormalizable theories from non-renormalizable interactions

By using Kikkawa's method the equivalence of the nonrenormalizable pair interaction ψ&#x0305;−ψψ2 to a renormalizable theory is proved. Equivalence relationships between a few other nonrenormalizable and renormalizable interactions are also indicated
