Post-Buckling Behavior of Laminated Composite Cylindrical Shells Subjected to Axial, Bending and Torsion Loads  [PDF]
Yengula Venkata Narayana, Jagadish Babu Gunda, Ravinder Reddy Pinninti, Markandeya Ravvala
World Journal of Engineering and Technology (WJET) , 2015, DOI: 10.4236/wjet.2015.34019
Abstract: In present work, post-buckling behavior of imperfect (of eigen form) laminated composite cylindrical shells with different L/D and R/t ratios subjected to axial, bending and torsion loads has been investigated by using an equilibrium path approach in the finite element analysis. The Newton-Raphson approach as well as the arc-length approach is used to ensure the correctness of the equilibrium paths up to the limit point load. Post-buckling behavior of imperfect cylindrical shells with different L/D and R/t ratios of interest is obtained and the theoretical knock-down factors are reported for the considered cylindrical shells.
A COMPARATIVE STUDY OF DOT AND SAT IN RURAL TERTIARY CARE HOSPITAL: A TWO YEARS RETROSPECTIVE STUDY
Jagadish Babu D.* and K. Jyothi
International Journal of Pharmaceutical Sciences and Research , 2012,
Abstract: Directly observed therapy (DOT) of tuberculosis patients talking their drugs is supposed to improve treatment completion and outcome .we compared DOT and Self Administered therapy (SAT), in which patients on the same drug regimen are not, observed taking their pills, to assess the effect of each on the success of tuberculosis treatment. This was the two year (2010 and 2011) retrospective study of tuberculosis patients admitted to the AH and RC.A total of 308 patients cases were analyzed. The majority of the cases were within 21-40 years TB patients were 38.96% of the total. Among the all TB patients with chronic illness others were 18(58.44%) more. Among 308 patients TB patients 131(42.53%) TB patients undergone DOT and 177 (57.46%) TB patient’s undergone SAT therapy. The comparative outcome between DOT and SAT were 110(86.61%) of cure and in SAT were 90 (57.32%). Only 5(03.93%) treatment failure, acquired drug resistance 01(00.78%), follow up lost were 11(08.66%) in DOT as compared to SAT 23(14.64%), 06(03.82%), 23(14.64%) respectively. There is no relapse and death in DOT therapy but in SAT therapy relapse were 10(06.36%) and deaths were 05(03.18%). There were large and significant difference in the cure, treatment failure, relapse and death rates between TB patient who receive DOT and SAT therapy respectively.
Povidone Iodine - Revisited
Palakuru SK,Raja Babu P,Jagadish Reddy G,Uttam A
Indian Journal of Dental Advancements , 2011, DOI: 10.5866/3.3.617
Abstract: Povidone Iodine or polyvinyl pyrrolidone-iodine is an iodophor and a broad spectrum antimicrobial agent delivered in many forms including powders, gels, lotions, ointments, sprays and mousses. Compared to other similar compounds Povidone iodine is highly soluble and less toxic making it widely suitable for surgical asepsis and wound dressing. In dentistry it is used for pre surgical skin preparation, pre procedural rinse to reduce bacteremia and microbial load in aerosols, root canal irrigant and intracanal medicament.
Existence and Stability of Equilibrium Points in the Robe’s Restricted Three-Body Problem with Variable Masses  [PDF]
Jagadish Singh, Oni Leke
International Journal of Astronomy and Astrophysics (IJAA) , 2013, DOI: 10.4236/ijaa.2013.32013
Abstract:

The positions and linear stability of the equilibrium points of the Robe’s circular restricted three-body problem, are generalized to include the effect of mass variations of the primaries in accordance with the unified Meshcherskii law, when the motion of the primaries is determined by the Gylden-Meshcherskii problem. The autonomized dynamical system with constant coefficients here is possible, only when the shell is empty or when the densities of the medium and the infinitesimal body are equal. We found that the center of the shell is an equilibrium point. Further, when k1; k being the constant of a particular integral of the Gylden-Meshcherskii problem; a pair of equilibrium point, lying in the \"\"-plane with each forming triangles with the center of the shell and the second primary exist. Several of the points exist depending on k; hence every point inside the shell is an equilibrium point. The linear stability of the equilibrium points is examined and it is seen that the point at the center of the shell of the autonomized system is conditionally stable; while that of the non-autonomized system is unstable. The triangular equilibrium points on the \"\"-plane of both systems are unstable.

The Collinear Libration Points in the Elliptic R3BP with a Triaxial Primary and an Oblate Secondary  [PDF]
Jagadish Singh, Aishetu Umar
International Journal of Astronomy and Astrophysics (IJAA) , 2014, DOI: 10.4236/ijaa.2014.42034
Abstract:

This paper examines the motion of a dust grain around a triaxial primary and an oblate companion orbiting each other in elliptic orbits about their common barycenter in the neighborhood of collinear libration points. The positions and stability of these points are found to be affected by the triaxiality and oblateness of the primaries, and by the semi-major axis and eccentricity of their orbits. The stability behavior of the collinear points however remains unchanged; they are unstable in the Lyapunov sense.

Periods, Eccentricities and Axes around L4,5 in the ER3BP under Radiating and Oblate Primaries  [PDF]
Aishetu Umar, Jagadish Singh
International Journal of Astronomy and Astrophysics (IJAA) , 2014, DOI: 10.4236/ijaa.2014.44061
Abstract: In the framework of the elliptic restricted three-body problem, using a semi-analytic approach, we investigate the effects of oblateness, radiation and eccentricity of both primaries on the periodic orbits around the triangular Lagrangian points of oblate and luminous binary systems. The frequencies of the long and short orbits of the periodic motion are affected by the oblateness and radiation of both primaries, so are their eccentricities, semi-major and semi-minor axes.

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0099182
Abstract: The major limiting factor for production and productivity of finger millet crop is blast disease caused by Magnaporthe grisea. Since, the genome sequence information available in finger millet crop is scarce, comparative genomics plays a very important role in identification of genes/QTLs linked to the blast resistance genes using SSR markers. In the present study, a total of 58 genic SSRs were developed for use in genetic analysis of a global collection of 190 finger millet genotypes. The 58 SSRs yielded ninety five scorable alleles and the polymorphism information content varied from 0.186 to 0.677 at an average of 0.385. The gene diversity was in the range of 0.208 to 0.726 with an average of 0.487. Association mapping for blast resistance was done using 104 SSR markers which identified four QTLs for finger blast and one QTL for neck blast resistance. The genomic marker RM262 and genic marker FMBLEST32 were linked to finger blast disease at a P value of 0.007 and explained phenotypic variance (R2) of 10% and 8% respectively. The genomic marker UGEP81 was associated to finger blast at a P value of 0.009 and explained 7.5% of R2. The QTLs for neck blast was associated with the genomic SSR marker UGEP18 at a P value of 0.01, which explained 11% of R2. Three QTLs for blast resistance were found common by using both GLM and MLM approaches. The resistant alleles were found to be present mostly in the exotic genotypes. Among the genotypes of NW Himalayan region of India, VHC3997, VHC3996 and VHC3930 were found highly resistant, which may be effectively used as parents for developing blast resistant cultivars in the NW Himalayan region of India. The markers linked to the QTLs for blast resistance in the present study can be further used for cloning of the full length gene, fine mapping and their further use in the marker assisted breeding programmes for introgression of blast resistant alleles into locally adapted cultivars.
Collinear Libration Points in the Photogravitational CR3BP with Zonal Harmonics and Potential from a Belt  [PDF]
Jagadish Singh, Joel John Taura
International Journal of Astronomy and Astrophysics (IJAA) , 2015, DOI: 10.4236/ijaa.2015.53020
Abstract: We have studied a reformed type of the classic restricted three-body problem where the bigger primary is radiating and the smaller primary is oblate; and they are encompassed by a homogeneous circular cluster of material points centered at the mass center of the system (belt). In this dynamical model, we have derived the equations that govern the motion of the infinitesimal mass under the effects of oblateness up to the zonal harmonics J4 of the smaller primary, radiation of the bigger primary and the gravitational potential generated by the belt. Numerically, we have found that, in addition to the three collinear libration points Li (i = 1, 2, 3) in the classic restricted three-body problem, there appear four more collinear points Lni (i = 1, 2, 3, 4). Ln1 and Ln2 result due to the potential from the belt, while Ln3 and Ln4 are consequences of the oblateness up to the zonal harmonics J4 of the smaller primary. Owing to the mutual effect of all the perturbations, L1 and L3 come nearer to the primaries while Ln3 advances away from the primaries; and L2 and Ln1 tend towards the smaller primary whereas Ln2 and Ln4 draw closer to the bigger primary. The collinear libration points Li (i = 1, 2, 3) and Ln2 are linearly unstable whereas the Ln1, Ln3 and Ln4 are linearly stable. A practical application of this model could be the study of motion of a dust particle near a radiating star and an oblate body surrounded by a belt.
THE ‘MAN OF GOD WHO CAME FROM JUDAH’ (2 KINGS 23:17-18): IN SEARCH OF THE FATE OF AMOS?
Masiiwa Ragies Gunda
Scriptura , 2013, DOI: 10.7833/111-1-33
Abstract: The prophetic book of Amos is widely studied yet one question remains unanswered: What happened to the prophet? This article attempts to answer this question. This article notes the brevity of the ministry of Amos as an indicator to a bad ending. By analyzing the narratives in 1 Kings 13 and 2 Kings 23, this article highlights similarities between Amos and the unnamed man of God such as place of origin, name of reigning king, centrality of Bethel and the lion. It is argued that on the balance of probabilities, Amos was a martyr. Through this analysis, this article argues that from Amos, Christians can learn from word and deed. Such an end is instructive for contemporary Christians faced with the options of being good neighbours or faithful believers. Overall, this article contends that while Christians must not actively seek persecution, they cannot compromise their faith to avoid persecution. doi: 10.7833/111-1-33
Malignant melanoma of the oral cavity
Ebenezer Jagadish
Indian Journal of Dental Research , 2006,
Abstract: Oral malignant melanoma is a rare disease. The common sites of its occurrence are the palate and gingiva with the maxillary arch being affected 80% of the time. Because of their presence at relatively obscure areas in the oral cavity, most of the malignant melanomas of the oral cavity are diagnosed at a late stage. These lesions are associated with poor prognosis. The dental clinician must therefore carefully examine the head, neck, and oral cavity, and any pigmented lesion that may exhibit growth potential must be biopsied. This article describes a case of malignant melanoma that was present in the oral cavity and briefly reviews the relevant literature that explains the nature of this lesion.
