Ganglioneuroma Always A Histopathological Diagnosis

Neuroblastoma, ganglioneuroblastoma and ganglioneuroma arise from sympathetic tissue in the neck, posterior mediastinum, adrenal gland, retroperitoneum and pelvis Ganglioneuromas are commonly seen in childhood. They are highly differentiated benign tumors and are compatible with long-term disease free survival. Retroperitoneal localization is relatively frequent for these tumors. Due to its rarity and lack of specific radiological findings diagnosis is always postoperative. Here, we present a case of Retroperitoneal ganglioneuroma which was undiagnosed before surgery

Cloud Based Application Development for Accessing Restaurant Information on Mobile Device using LBS

Over the past couple of years, the extent of the services provided on the mobile devices has increased rapidly. A special class of service among them is the Location Based Service(LBS) which depends on the geographical position of the user to provide services to the end users. However, a mobile device is still resource constrained, and some applications usually demand more resources than a mobile device can a ord. To alleviate this, a mobile device should get resources from an external source. One of such sources is cloud computing platforms. We can predict that the mobile area will take on a boom with the advent of this new concept. The aim of this paper is to exchange messages between user and location service provider in mobile device accessing the cloud by minimizing cost, data storage and processing power. Our main goal is to provide dynamic location-based service and increase the information retrieve accuracy especially on the limited mobile screen by accessing cloud application. In this paper we present location based restaurant information retrieval system and we have developed our application in Android.Comment: 11 pages, 10 figure

Interpreting the sub-linear Kennicutt-Schmidt relationship: The case for diffuse molecular gas

Recent statistical analysis of two extragalactic observational surveys strongly indicate a sublinear Kennicutt-Schmidt (KS) relationship between the star formation rate (Sigsfr) and molecular gas surface density (Sigmol). Here, we consider the consequences of these results in the context of common assumptions, as well as observational support for a linear relationship between Sigsfr and the surface density of dense gas. If the CO traced gas depletion time (tau_mol) is constant, and if CO only traces star forming giant molecular clouds (GMCs), then the physical properties of each GMC must vary, such as the volume densities or star formation rates. Another possibility is that the conversion between CO luminosity and Sigmol, the XCO factor, differs from cloud-to-cloud. A more straightforward explanation is that CO permeates the hierarchical ISM, including the filaments and lower density regions within which GMCs are embedded. A number of independent observational results support this description, with the diffuse gas comprising at least 30% of the total molecular content. The CO bright diffuse gas can explain the sublinear KS relationship, and consequently leads to an increasing tau_mol with Sigmol. If Sigsfr linearly correlates with the dense gas surface density, a sublinear KS relationship indicates that the fraction of diffuse gas fdiff grows with Sigmol. In galaxies where Sigmol falls towards the outer disk, this description suggests that fdiff also decreases radially.Comment: 8 pages, 4 figures, to appear in MNRAS, comments welcom

Case report of a new technique for with posterior cruciate ligament avulsion fractures treated with a mini transverse incision

Posterior cruciate ligament (PCL) is a strong stabilising ligament of the knee joint originating from posterior part of Intercondylar eminence oof tibia and attaches to the anterior part of medial surface of lateral condyle of femur. The PCL plays a major role in knee stabilization, and are statistically one of the rarest injuries around the knee. Due to the surrounding neurovascular elements in the popliteal space, very few open approaches to repair such injury were performed. The ‘‘safe transverse mini-incision approach’’ to PCL avulsion fracture is a simple approach, does not require exploration of the neurovascular elements, and produced satisfactory results in the majority of patients

Oxford: people and townscape

The purpose of this thesis is to shed light on the role of the urban configuration in bringing Residents and Visitors into ‘common space’ and interface. The study focuses on the city centre of Oxford, in South East England, which is a thriving hub of students, tourists and local inhabitants. Through a historic review of Oxford, the report provides a context for understanding the spatial aspects of the socio-economic processes prevalent through centuries illustrating the emergent spatial pattern contributing to the city’s socio-spatial organisation that we witness today. Space Syntax theories and methodology coupled with on-site observations are implemented to evaluate the performance and social implication embedded in the urban spaces. The thesis discusses the urban configuration in the light of Hillier’s notion of ‘Centrality as a process’ analysing the significance of the city’s growth in preserving life of Heritage and in playing an active role in the city’s urban life. The spatio-functional analysis of the urban framework supported by empirical data provides insights into the movement patterns of the Resident group. The thesis also focuses in particular on the observation and analysis of the movement pattern of the Tourist in conjunction with the street character and the afforded visual fields. The analysis of co-presence follows the analysis of movement patterns as the public urban spaces, from the convex spaces of transition to the convex spaces of stasis, are studied and presented with respect to their roles in the construction of interfaces. The report concludes that the spatial pattern of the city emergent from a prevailing trade route, has systematically oriented itself to the micro-economic activity at the historic core in effect bringing the city’s inhabitants into an interface. Further, the analysis of movement patterns of tourists suggests that the visual fields afforded by the layout of the street structure has a significant effect on tourist movement and behaviour whilst the spatial layout of the city centre brings them into an interface with the Resident population

Effective nucleon mass and the nuclear caloric curve

Assuming a schematic form of the nucleon effective mass as a function of nuclear excitation energy and mass, we provide a simple explanation for understanding the experimentally observed mass dependence of the nuclear caloric curve. It is observed that the excitation energy at which the caloric curve enters into a plateau region, could be sensitive to the nuclear mass evolution of the effective nucleon mass.Comment: 5 pages, 5 figures, Accepted for publication in Phys.

Symmetry Energy in the Equation of State of Asymmetric Nuclear Matte

The symmetry energy is an important quantity in the equation of state of isospin asymmetric nuclear matter. This currently unknown quantity is key to understanding the structure of systems as diverse as the neutron-rich nuclei and neutron stars. At TAMU, we have carried out studies, aimed at understanding the symmetry energy, in a variety of reactions such as, the multifragmentation of $^{40}$Ar, $^{40}$Ca + $^{58}$Fe, $^{58}$Ni and $^{58}$Ni, $^{58}$Fe + $^{58}$Ni, $^{58}$Fe reactions at 25 - 53 AMeV, and deep-inelastic reactions of $^{86}$Kr + $^{124,112}$Sn, $^{64,58}$Ni (25 AMeV), $^{64}$Ni + $^{64,58}$Ni, $^{112,124}$Sn, $^{232}$Th, $^{208}$Pb (25 AMeV) and $^{136}$Xe + $^{64,58}$Ni, $^{112,124}$Sn, $^{232}$Th, $^{197}$Au (20 AMeV). Here we present an overview of some of the results obtained from these studies. The results are analyzed within the framework of statistical and dynamical models, and have important implications for future experiments using beams of neutron-rich nuclei.Comment: 10 pages, 4 figures, talk presented at VI Latin American Symposium on Nuclear Physics and Application
