International Journal of Biomedical and Advance Research , 2013, DOI: 10.7439/ijbar.v4i1.899
Abstract: Introduction- Post graduate students during OPD hours, sometimes find it difficult to reach the provisional diagnosis. There is rising tendency to send patients to investigations without utilizing history and clinical findings to reach the diagnosis. Ideal approach- Residents should take careful history, do thorough clinical examination and develop a thought process to utilize these findings to come to a provisional diagnosis. Aim - Use of “One Minute Preceptor” in surgery post graduate residents in surgery OPD. Objectives- The tendency to rush for investigations should change and they should utilize the investigative tools to reinforce their diagnosis rather than getting / seeking readymade diagnosis. Innovation- To achieve this goal, the use of ‘One Minute Preceptor’ was adapted which provides a different approach compared to the traditional teaching. Materials And Methods – 1.Preproject questionnaire 2.Implementation 3.Interval feedback 4. Assessment Results: The use of “One Minute Preceptor’ in Surgery residents in ambulatory setup of Surgery OPD has positively contributed in achieving objectives of developing thought process to reach provisional diagnosis by utilizing history and clinical examination.

Keratinization and its Disorders
Shibani Shetty,Gokul S.
Oman Medical Journal , 2012,
Abstract: Keratins are a diverse group of structural proteins that form thei ntermediate filament network responsible for maintaining the structural integrity of keratinocytes. In humans, there are around 30 keratin families divided into two groups, namely, acidic and basic keratins, which are arranged in pairs. They are expressed in a highly specific pattern related to the epithelial type and stage of cellular differentiation. A total of 54 functional genes exist which codes for these keratin families. The expression of specific keratin genes is regulated by the differentiation of epithelial cells within the stratifying squamous epithelium. Mutations in most of these genes are now associated with specific tissue fragility disorders which may manifest both in skin and mucosa depending on the expression pattern. The keratins and keratin-associated proteins are useful as differentiation markers because their expression is both region specific and differentiation specific. Antibodies to keratin are considered as important tissue differentiation markers and therefore are an integral aid in diagnostic pathology. The present review discusses the structure of keratin, the various types of keratin and their distribution and the disorders associated with keratinization with special emphasis on the disorders of the oralcavity. A brief note on the clinical significance of keratin is also mentioned.
Degrees of Freedom of MIMO Cellular Networks: Decomposition and Linear Beamforming Design
Gokul Sridharan,Wei Yu
Computer Science , 2013,
Abstract: This paper investigates the symmetric degrees of freedom (DoF) of MIMO cellular networks with G cells and K users per cell, having N antennas at each base station and M antennas at each user. In particular, we investigate achievability techniques based on either decomposition with asymptotic interference alignment (IA) or linear beamforming schemes, and show that there are distinct regimes of (G,K,M,N) where one outperforms the other. We first note that both one-sided and two-sided decomposition with asymptotic IA achieve the same degrees of freedom. We then establish specific antenna configurations under which the DoF achieved using decomposition based schemes is optimal by deriving a set of outer bounds on the symmetric DoF. For linear beamforming schemes, we first focus on small networks and propose a structured approach to linear beamforming based on a notion called packing ratios. Packing ratio describes the interference footprint or shadow cast by a set of transmit beamformers and enables us to identify the underlying structures for aligning interference. Such a structured beamforming design can be shown to achieve the optimal spatially normalized DoF (sDoF) of two-cell two-user/cell network and the two-cell three-user/cell network. For larger networks, we develop an unstructured approach to linear interference alignment, where transmit beamformers are designed to satisfy conditions for IA without explicitly identifying the underlying structures for IA. The main numerical insight of this paper is that such an approach appears to be capable of achieving the optimal sDoF for MIMO cellular networks in regimes where linear beamforming dominates asymptotic decomposition, and a significant portion of sDoF elsewhere. Remarkably, polynomial identity test appears to play a key role in identifying the boundary of the achievable sDoF region in the former case.

Journal of Crystallization Process and Technology (JCPT) , 2012, DOI: 10.4236/jcpt.2012.24018
Abstract: A new alkali metallo-organic single crystal of Lithium Sodium Acid Phthlate (LiNaP) complex has been synthesized from aqueous solution in the equimolar ratio 3:1:2. Transparent and bulk single crystals of dimension 9 × 4 ×2 mm3 have been grown from the conventional slow-cooling technique. The crystal structure of the compound has been solved from single crystal X-ray diffraction. The compound 2[C8H4O3]4-Li3+Na+ crystallizes in triclinic system with a space group of Pī having cell dimensions a = 7.5451(2) ? b = 9.8422(3) ? c = 25.2209(7) ? α = 80.299(2); β = 89.204(2); γ = 82.7770(10). FTIR measurement was carried out fo? LiNaP to study the vibrational structure of the compound. The various functional groups present in the molecule and the role of H-bonds in stabilizing the crystal structure of the compound have been explained. Optical absorption properties were studied for the grown crystal using UV-Vis-NIR spectrum. Thermal measurements were carried out for LiNaP to determine the thermal strength as well as to ascertain the hydrated nature of the crystal. Third order nonliner optical studies have also studied by Z-scan techniques. Nonlinear absorption and nonlinear refractive index were found out and the third order bulk susceptibility of compound was also estimated. The results of all studies have been discussed in detail.
FEM Approach for Transient Heat Transfer in Human Eye  [PDF]

Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.410A2003

In this paper, a bio-heat transfer model of temperature distribution in human eye is discussed using appropriate boundary conditions for cornea and sclera. Variational finite element method with Crank-Nicolson scheme is used to calculate the transient temperature distribution in normal human eye. The temperature with and without the effect of blood perfusion and metabolism on retina is simulated and compared for various ambient temperatures, evaporation rates and lens thermal conductivities. The obtained results are compared with experimental results and past results found in literatures. The results show that the steady state corneal temperature is achieved in around 31 and 45 minute of exposure at ambient temperatures 10 and 50 respectively. Steady state eye temperature is achieved earlier at higher evaporation rate. Similar result is achieved for higher lens thermal conductivity and also for lower ambient temperature.

Elemental mercury poisoning caused by subcutaneous and intravenous injection: An unusual self-injury
Wale Jaywant,Yadav Pankaj,Garg Shairy
Indian Journal of Radiology and Imaging , 2010,
Abstract: Elemental mercury poisoning most commonly occurs through vapor inhalation as mercury is well absorbed through the lungs. Administering subcutaneous and intravenous elemental mercury is very uncommon but with only a few isolated case reports in the literature. We present an unusual case of elemental mercury poisoning in a 20-year-old young male who presented with chest pain, fever, and hemoptysis. He had injected himself subcutaneously with elemental mercury obtained from a sphygmomanometer. The typical radiographic findings in the chest, forearm, and abdomen are discussed, with a review of the literature.
Integral analysis of laminar indirect free convection boundary layers with weak blowing for Schmidt no. ~ 1
Baburaj A. Puthenveettil,Jaywant H. Arakeri
Physics , 2004, DOI: 10.1016/j.icheatmasstransfer.2004.08.017
Abstract: Laminar natural convection at unity Schmidt number over a horizontal surface with a weak normal velocity at the wall is studied using an integral analysis. To characterise the strength of the blowing, we define a non-dimensional parameter called the blowing parameter. After benchmarking with the no blowing case, the effect of the blowing parameter on boundary layer thickness, velocity and concentration profiles is obtained. Weak blowing is seen to increase the wall shear stress. For blowing parameters greater than unity, the diffusional flux at the wall becomes negligible and the flux is almost entirely due to the blowing.
A Pitching Foil with a Flexible flap Creates an Orderly Jet
Sachin Y. Shinde,Jaywant H. Arakeri
Physics , 2010,
Abstract: We experimentally studied the effect of flexibility on the flow produced by sinusoidally pitching foil in quiescent fluid. The rigid foil produces a weak, divergent and meandering jet. On the contrary, the foil with a flexible flap produces an orderly, narrow, coherent jet. It has been observed that such orderly jet is produced when the flap has appropriate flexibility. The jet produced in quiescent fluid by the flexible foil is accompanied by a corresponding thrust. In that sense, this is simple and different type of hovering.
