Elastodynamics response of Green’s function and influence function in fluid saturated incompressible porous medium
R Kumar, A Miglani, S Kumar
International Journal of Engineering, Science and Technology , 2011,
Abstract: The article reports on a methodology to synthesize the response of Green’s function and influence function in fluid saturated incompressible porous half space. As an application, the disturbance due to concentrated and distributed loads in normal and tangential direction is investigated by employing the Laplace and Fourier transforms. The integral transforms have been inverted by using a numerical technique to obtain the components of displacement, stress and pore pressure in physical domain. The results concerning these quantities are given and illustrated graphically to depict the effect of pore pressure. A particular case of interest has been deduced from the present investigation.
Immunoglobulin G4-associated cholangitis mimicking cholangiocarcinoma in a young boy

Journal of Postgraduate Medicine , 2010,
Abstract: Autoimmune pancreatitis is a rare form of chronic pancreatitis, which commonly mimics pancreatic carcinoma. Immunoglobulin G4-associated cholangitis (IAC) is a rare type of autoimmune pancreatitis associated with bile duct involvement, which can present with or without pancreatic involvement. Usually, the bile duct involvement is in the form of multiple intra-and extra-hepatic strictures mimicking primary sclerosing cholangitis. Rarely, there can be an isolated stricture which mimics cholangiocarcinoma. Differentiating these from cholangiocarcinoma, though extremely difficult, is of critical importance since it can be treated without surgical intervention. Most cases with rare presentation mimicking cholangiocarcinoma have been reported in elderly patients. We present one such rare presentation of autoimmune pancreatitis in a young 13-year-old patient in whom hepaticojejunostomy was done for a hilar stricture, which later turned out to be related to IAC. To our knowledge this is the first reported case of its kind from India.
Comparative evaluation of the surface tension and the pH of calcium hydroxide mixed with five different vehicles:An in vitro study
Poorni S,Miglani Revathi,Srinivasan M,Indira R
Indian Journal of Dental Research , 2009,
Abstract: Aim: The aim of this study was to evaluate the surface tension and pH of five different vehicles that are used as potential agents to mix calcium hydroxide in root canal treatments and to compare them with the final surface tension and pH of calcium hydroxide mixed with these vehicles. Materials and Methods: The study was carried out in two phases. In Phase I, the surface tension and pH of five vehicles (distilled water, saline, anesthetic solution, chlorhexidine, and glycerin) were evaluated using a Du Nuoy Tensiometer and a pH Meter. In Phase II, a predetermined amount of calcium hydroxide was mixed with the individual vehicles and the surface tension and pH was determined. In each group, seven samples were evaluated. Results: Among the individual vehicles, chlorhexidine had the least surface tension values (39.8+1.1 dynes/cm). Among the various calcium hydroxide mixtures, calcium hydroxide with chlorhexidine showed the least surface tension values (36.4+1.1 dynes/cm). All the vehicles showed an acidic pH ranging from 5 to 6.5. There was a significant increase in the pH values with the addition of calcium hydroxide to the respective vehicles. The calcium hydroxide mixtures had an alkaline pH ranging from 9 to 11.5; the highest pH was observed for calcium hydroxide mixed with distilled water and saline (11.5+0.2). Conclusion: The surface tension and pH of the vehicles directly influenced the surface tension and pH of the calcium hydroxide mixtures. Chlorhexidine was found to be a better vehicle for calcium hydroxide when used as an intracanal medicament.

Thoraco-abdominal neuroenteric cyst: A case report and review of the literature
N Agarwal, N Kaur, R Miglani, P Saini, D Nebhnani, A Gupta
South African Journal of Child Health , 2011,
Abstract: Neuroenteric cysts are rare congenital anonalies, presenting in infancy or childhood. Only a few cases of posterior mediastinal neuroenteric cysts have been reported. A 12-year-old girl presented to our hospital with a neglected mildly painful cyst in the posterior mediastinum and retroperitoneum. Magnetic resonance imaging revelealed scoliosis of the thoracic spine, hemivertebrae T6 - 7, and a large hyperintense (on T2-weighted images) cystic lesion in the posterior mediastinum. The lesion had no intraspinal communication, but extended into the abdomen between the liver and kidney. Despite the long history and spatial extent of the lesion, it was excised uneventfully through a right thoracotomy. Microscopy of the cyst wall revealed partially disrupted cuboidal epithelium, muscle fibres, inflammatory cells, and, bony and cartilaginous elements. Enterogenous duplication cysts of foregut origin with vertebral anomalies are referred to as neuroenteric cysts. This is a probably only the second reported case of thoraco-abdominal neurogenic cyst originating in the posterior mediastinum.
Plane Strain Deformation of a Poroelastic Half-space in Welded Contact with Transversely Isotropic Elastic Half-Space
International Journal of Engineering Science and Technology , 2012,
Abstract: The Biot linearized theory for fluid saturated porous materials is used to study the plane strain deformation of an isotropic, homogeneous, poroelastPic half space in welded contact with a homogeneous, transversely isotropic, elastic half space caused by an inclined line-load in elastic half space. The integral expressions for the displacements and stresses in the two half spaces in welded contact are obtained from the corresponding expressions for an unbounded transversely isotropic elastic and poroelastic medium by applying boundary conditions at the interface. The integrals for the inclined line-load are solved analytically for the limiting casei.e. undrained conditions in high frequency limit. The undrained displacements, stresses and pore pressure are shown graphically. Expression for the pore pressure is also calculated for undrained conditions in the high frequency limit.
Deformation due to distributed sources in micropolar thermodiffusive medium
Sachin Kaushal,Aseem Miglani
Mathematical Sciences Quarterly Journal , 2010,
Abstract: The general solution to the field equations in micropolar generalized thermodiffusive in the context of G-L theory is investigated by applying the Laplace and Fourier transform's as a result of various sources. An application of distributed normal forces or thermal sources or potential sources has been taken to show the utility of the problem. To get the solution in the physical form, a numerical inversion technique has been applied. The transformed components of stress, temperature distribution and chemical potential for G-L theory and CT theory has been depicted graphically and results are compared analytically to show the impact of diffusion, relaxation times and micropolarity on these quantities. Some special case of interest are also deduced from present investigation.
Radiative Effect on Flow and Heat Transfer over a Vertically Oscillating Porous Flat Plate Embedded in Porous Medium with Oscillating Surface Temperature  [PDF]
Monika Miglani, Net Ram Garg, Mukesh Kumar Sharma
Open Journal of Fluid Dynamics (OJFD) , 2016, DOI: 10.4236/ojfd.2016.62010
Abstract: The effect of radiation on flow and heat transfer over a vertically oscillating porous flat plate embedded in porous medium with oscillating surface temperature is investigated. The analytic solutions of momentum and energy equations are obtained. The velocity and temperature profiles are computed. The frictional force at the plate due to viscosity of fluid is estimated in terms of non dimensional skin friction coefficient and heat convection at the plate is estimated in the form of Nusselt number. The effects of physical parameters Prandtl number Pr, Grashof number Gr, Suction parameter S and radiative parameter R on velocity and temperature profiles are analyzed through graphs. The effects of oscillation on the velocity and temperature profiles are shown through 3-D surface plot.

Abstract: 卵黄蛋白原(vitellogenin,Vg)是主要的卵黄蛋白前体,在雌虫血餐之后在脂肪体内大量合成。卵黄蛋白原的调节元件已经被用于驱动蚊子(与寄生虫发生最大相互作用的场所)中抗寄生基因的组织特异性表达。不过,迄今为止,对在印度引起60%~70%疟疾发生的库态按蚊Anophelesculicifacies中的内源启动子尚未进行过分析。本研究通过PCR扩增了包括5′端上游调节区在内的库态按蚊A.culicifacies卵黄蛋白原基因,并命名为AncuVg(GenBank登录号为JN113091)。它含有一个大约6.2kb的开放阅读框,编码2052个氨基酸,具有一个16个氨基酸残基的推断的信号肽。也含有一个N_Vitellogenin区和一个VWF型D区,这两个区在其他昆虫卵黄蛋白原中也保守。估计多肽分子量为238.0kDa,含有4个共有的(RXXR/S)切割位点,C端附近有一个GL/ICG基序,其后是9个半胱氨酸残基和1个位于GL/ICCG基序上游第18个氨基酸残基处的DGXR基序。在推断的氨基酸序列上发现3个聚丝氨酸区,其中2个位于氨基端,1个位于羧基端。根据同义密码子相对使用概率值,通过有效密码子数,测定了蚊子卵黄蛋白原基因密码子的偏倚性程度。也预测了库态按蚊A.culicifaciesVg的三维结构。分析了AncuVg基因,以理解Vg基因的转录调节。对Vg基因5′端上游区进行的系统发育分析表明,它们聚类于蚊子的3大分枝。也用各种生物信息学工具分析分析了Vg的同源性和特征。
