Apatite Microstructure and Composition in Manganese Formation of Eastern Ghats, Orissa, India  [PDF]
Subhasmita Jena, B.K. Mohapatra, P. P. Singh
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2011, DOI: 10.4236/jmmce.2011.105030
Abstract: Apatite grains in a stratabound manganese ore body from Eastern Ghats in Leliguma, Koraput district south Orissa, India were studied under optical and electron microscope. Apatite shows bimodal occurrence: one associated with granite/pegmatitic phase and other with manganese phase, and exhibits different microstructure and composition. Apatite in pegmatitic association (occurring as inclusion in quartz and feldspar) is small in size and occurs as subhedral grains having irregular boundaries and poor in manganese content (MnO: 0.16%). Apatite associated with manganese mineral phases (cryptomelane / romanechite) is mostly euhedral, relatively larger in size, contains higher manganese value, and exhibits some peculiar features like twinning, zoning, overgrowth, and occasionally contains inclusion of quartz and feldspar grains. Apatite grains occurring as inclusions within quartz and feldspar are of hydrothermal origin and formed along with pegmatitic minerals. Such apatite is almost devoid of manganese but relatively enriched in Sr, F and LREE content. The apatite in manganese mineral association formed during supergene process. The apatite of latter generation appears as idiomorphic crystals; contains up to 6.85% of MnO in solid solution and shows relatively higher HREE values. The higher HREE values may be due to its derivation from stratiform Mn-ore bodies and associated granitised rock during remobilization, solution and precipitation of Mn –rich fluid along structurally weak planes resulting in development of a stratabound ore body.
Work-Life Balance Challenges for Indian Employees: Socio-Cultural Implications and Strategies  [PDF]
Atasi Mohanty, Lalatendu Kesari Jena
Journal of Human Resource and Sustainability Studies (JHRSS) , 2016, DOI: 10.4236/jhrss.2016.41002
Abstract: The changing nature at workplace coupled with changes in socio-cultural level has led to imbalance in the work and personal lives of employees all over. Increasing demand, rising awareness among women, increasing stress levels, increasing family levels etc., have made it difficult for people to cope with their work and family lives. With increasing stress levels and demands at the workplaces, attrition rate in organization is increasing. Therefore, the present day organizations are required to create a flexible environment which would help employees to manage their work and family together. This paper brings forth such issues and practices prevailing in Indian context. The materials reviewed were obtained through searches of academic, business and sociological data base containing generalized research evidence and case study findings. It includes academic journal articles, books, research reports and materials oriented to business community.
Indian Streams Research Journal , 2012,
Abstract: The major characters in Shashi Deshpande's novels are educated, modern and working women. They crave to establish themselves as individuals having their own identity. They dislike being considered as appendages to men. A crisis of identity crops up when the women develop relationship with others. Bereft of support and confidence, they find themselves fettered in the chains of alienation as the situation lacks congeniality and compatibility.

High-field Current-carrying Capacity of Semiconducting Carbon Nanotubes
Debdeep Jena
Physics , 2008,
Abstract: It is shown that current saturation in semiconducting carbon nanotubes is indistinguishable from metallic nanotubes if the carrier density is above a critical value determined by the bandgap and the LO phonon energy. This feature stems from the higher number of current-carrying states in the semiconducting tubes due to the van-Hove singularity at the band-edge. Above this critical carrier density, the ensemble saturation velocity at high-fields is found to be independent of the bandgap, but strongly dependent on the carrier density, explaining recent observations.
Measurement of D-meson production in pp, p-Pb, and Pb-Pb collisions at the LHC with the ALICE detector
Chitrasen Jena
Physics , 2014, DOI: 10.1088/1742-6596/535/1/012027
Abstract: Heavy quarks are a powerful probe for investigating the properties of the Quark-Gluon Plasma created in heavy-ion collisions, since they are produced in initial hard scattering processes and experience all the stages of the medium evolution. ALICE has measured the production of $\mathrm{D}^0$, $\mathrm{D}^+$, $\mathrm{D}^{*+}$, and $\mathrm{D}_{\mathrm{s}}^+$ mesons at central rapidity in their hadronic decay channels in various collision systems and energies. We present recent results for D-meson production measured by the ALICE Collaboration in pp collisions at $\sqrt{s}=7$ and 2.76 TeV, Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}=2.76$ TeV and p-Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02$ TeV.
A Novel Secure Key Agreement Protocol using Trusted Third Party
Sairam Kulkarni,Debashih Jena,Sanjay Kumar Jena
International Journal of Computer Science and Security , 2007,
Abstract: In the past, several key agreement protocols are proposed on password based mechanism. These protocols are vulnerable to dictionary attacks. Storing plain text version of password on server is not secure always. In this paper we utilize the service of a trusted third party, i.e., the Key Distribution server (KDS) for key agreement between the hosts. Now-a-days in large working environments two party key agreement protocols are being rarely used. In this proposed scheme, instead of storing plain text version of password we store one way hash of the password at the server. Every host and server agree upon family of commutative one-way hash functions, using which host authentication is done when a host applies for session key with KDS. Host establishes one time key with server using which server authentication is done. Due to this man-in-the middle attacks are defeated. The proposed protocol is based on Diffie-Hellman key exchange protocol.
Forecasting the Rainfall Pattern on Upstream of Hirakud Reservoir Using L-Moment for Accessing the Inflow  [PDF]
Krishna Kumar Gupta, Anil Kumar Kar, Joygopal Jena, Dipti Ranjan Jena
Journal of Water Resource and Protection (JWARP) , 2017, DOI: 10.4236/jwarp.2017.912085
Abstract: Changes in the rainfall pattern are a challenge for filling schedule of reservoir, when it is fulfilling various demands. In monsoon fed reservoirs, the target remains for attaining full reservoir capacity in order to meet various demands during non-monsoon period and the flood control. The planners always eye towards the inflow trend and perspective frequency of rainfall in order to counter the extreme events. In this study, the case of Hirakud reservoir of Mahanadi basin of India is considered as this reservoir meets various demands as well as controls devastating floods. The inflow trend has been detected by using Mann Kendall test. The frequency analysis of monthly rainfall is calculated using L-moment program for finalizing a regional distribution. The falling trend in inflow to reservoir is visualized in the month of July and August. The Wakeby distribution is found suitable for the monthly rainfall of July, September and October, where as in June and August, General Extreme Value (GEV), General Normal (GN) and Pearson Type-III (PT-III) distributions are found suitable. The regional growth factors for the 20, 40, 50 and 100-year return period rain-falls along with inflow to reservoir observed between 1958-2010 are calculated in this study as a referral for reservoir operation policy.
Medullary carcinoma of the thyroid - an unusual case of hyalinizing trabecular adenoma - like variant (encapsulated)
Vidya Bhat, Madhusmita Jena
Internet Journal of Medical Update - EJOURNAL , 2012,
Abstract: Medullary thyroid carcinoma is a neoplasm occurring in sporadic and familial patterns. A rare variant of medullary thyroid carcinoma shows microscopic features similar to hyalinizing trabecular adenoma of thyroid. Detection of this variant requires a high index of suspicion and immunohistochemical confirmation by calcitonin positivity. We present a 36 years old female patient with a thyroid nodule which, on microscopy, displayed an encapsulated tumor with elongated cells arranged in trabecular pattern separated by hyalinized fibrous septae simulating a hyalinizing trabecular adenoma. Also present were spindle cells arranged in an organoid fashion. Most of the cells showed salt and pepper chromatin pattern. The lesion was negative for amyloid but showed diffuse calcitonin positivity indicative of a tumor of C-cell origin i.e. medullary carcinoma of thyroid – hyalinizing trabecular variant.

Clinical Ophthalmology , 2010, DOI: http://dx.doi.org/10.2147/OPTH.S10992
Abstract: pical administration of adrenergic receptor pharmaceutics and nerve growth factor Review (3196) Total Article Views Authors: Jena J Steinle Published Date June 2010 Volume 2010:4 Pages 605 - 610 DOI: http://dx.doi.org/10.2147/OPTH.S10992 Jena J Steinle Departments of Ophthalmology and Anatomy and Neurobiology, Hamilton Eye Institute, University of Tennessee Health Science Center, Memphis, TN 38163, USA Abstract: Topical application of nerve growth factor (NGF) and adrenergic receptor pharmaceutics are currently in use for corneal ulcers and glaucoma. A recent interest in the neuroprotective abilities of NGF has led to a renewed interest in NGF as a therapeutic for retinal and choroidal diseases. NGF can promote cell proliferation through actions of the TrkA receptor or promote apoptosis through receptor p75NTR. This understanding has led to novel interest in the role of NGF for diseases of the posterior eye. The role of β-adrenergic receptor agonists and antagonists for treatments of glaucoma, diabetic retinopathy, and their potential mechanisms of action, are still under investigation. This review discusses the current knowledge and applications of topical NGF and adrenergic receptor drugs for ocular disease.
