Abstract:

Idiopathic hypereosinophilic syndrome (IHES) is a disorder characterized by increased eosinophil count (eosinophilia) along with organ dysfunction secondary to organ infiltration of eosinophils and release of inflammatory markers [1-4], with no obvious cause for eosinophilia. The onset of symptoms is insidious in most of the cases and eosinophilia is detected incidentally. However, in others, the initial manifestations are severe and life-threatening due to the rapid evolution of cardiac or neurologic complications [5]. Renal involvement is rarely reported [6] in IHES. Herein we reported a case of IHES with predominant renal involvement as nephrotic syndrome with focal necrotizing IgA nephropathy.

Voltage Mode Universal Filter Using Current Differencing Buffered Amplifier as an Active Device  [PDF]
Sheikh Ajaz Bashir, Nisar Ahmed Shah
Circuits and Systems (CS) , 2012, DOI: 10.4236/cs.2012.33038
Abstract: Integrated filter circuit design resulted in desire for replacement of Inductors by active elements like Operational Amplifiers which led to the introduction of active filters. Active filter design has evolved over a period of time. Starting with OP AMPs, we have witnessed phenomenal growth of active component usage in filter design and development catering to varying requirements. This has contributed greatly in emergence of circuits with minimal limitations and advantages in terms of wide Bandwidth and High slew rates. Current Differencing Buffered Amplifier (CDBA) based active filter design has resulted in introduction of many novel circuits .This paper proposes a new Voltage-mode three input and Single output (TISO) multifunction filter based on single CDBA, four resistors and two capacitors. This second order filter circuit is capable of realizing various filter functions by choosing values of the three inputs variably. The natural frequency (ω0) can be tuned with passive components and the Q of the circuit is independent of (ω0) .The higher cascading capability of the circuit is ensured because of its low - output impedance. Further PSPICE-simulated results are in conformity with theoretical values.

The natural frequency (ω0) can be tuned with passive components and the Q of the circuit is independent of the higher cascading capability of the circuit is ensured because of its low - output impedance.

Abstract: A prospective study of 10 patients who had breast gangrene over a period of 6 years were analyzedAll the patients in the study group were female. Total of 10 patients were encountered who had breast gangrene. Six patients presented with breast gangrene on the right breast whereas four had on left breast. Out of 10 patients, three had breast abscess after teeth bite followed by gangrene, one had iatrogenic trauma by needle aspiration of erythematous area of breast under septic conditions. Four had history of application of belladonna on cutaneous breast abscess and had then gangrene. All were lactating female. Amongst the rest two were elderly, one of which was a diabetic who had gangrene of breast and had no application of belladonna. All except one had debridement under cover of broad spectrum antibiotics. Three patients had grafting to cover the raw area.Breast gangrene occurs rarely. Etiology is variable and mutifactorial. Teeth bite while lactation and the iatrogenic trauma by needle aspiration of breast abscess under unsterlised conditions could be causative. Uncontrolled diabetes can be one more causative factor for the breast gangrene. Belladonna application as a topical agent could be inciting factor. Sometimes gangrene of breast can be idiopathic. Treatment is antibiotics and debridement.Gangrene of breast is rare to see [1]. There are only few cases of breast gangrene reported in the literature. This is regarded as cosmetic blemish and is agony for the female. Gangrene of breast can be idiopathic or occurs after some secondary to some causative agent. Occurrence of breast gangrene in the diabetes, after application of a topical agent or of idiopathic cause is scarcely reported in literature. Its medico-surgical management is an emergency [2]. Treatment involves debridement, antibiotics and sometimes mastectomy. The aim was to study clinical presentation and management of patients with breast gangrene.A study of 10 female patients who presented with the bre
A Study of Network Based Mobility Management Schemes, 6LoWPAN Mobility, Open Issues and Proposed Solutions

Abstract: Wireless Sensor Nodes (SNs), the key elements for building Internet of Things (IOT), have been deployed widely in order to get and transmit information over the internet. With the introduction of IPv6 over Low Power Wireless Personal Area Network (6LoWPAN), it is possible to connect these constrained devices to IPv6 Networks and transmit IPv6 packets. The sensor nodes are being deployed/installed on many objects and some of them are mobile (moving) including mobile gadgets, physical objects (living or non-living) etc. These mobile objects require sufficient Mobility Management Schemes to take care of data transmission. Host based mobility protocols; MIPv6 and its extensions are not suitable for these resource constrained devices. In this paper our focus is to study PMIPv6 based mobility management and different Scenarios based on it along with sensor devices. Existing research has made many improvements in terms of HO latency but less attention has paid towards signaling cost and packet loss particularly in time critical areas. The study provides the complete survey of network based mobility management schemes, 6LoWPAN mobility, challenges associated with them and solutions to meet these challenges.

Abstract: Some experimental results on nuclear transparency effect in pC- and dC-interaction at 4.2 A GeV/c (JINR Dubna) are presented. The "half angle" ({\theta}1/2) technique was used and the particles with emission angle greater and less than {\theta}1/2 are considered separately. The results of the experimental study have been compared with the simulation data coming from the Dubna Cascade model. The values of average multiplicity, average momentum, and average transverse momentum of charged pions and protons are analyzed as a function of the number of identified protons in an event. We observed some behaviors for the data which could be considered as some nuclear transparency effects. The lasts have been divided into three main groups depending on their probable behavior: leading effect; cascade effect; medium effect.
Study of the behavior of nuclear modification factor in freeze-out state

Physics , 2013, DOI: 10.1088/1674-1137/37/2/024101
Abstract: One of the latest trends in the advancement of experimental high-energy physics is to identify the quark gluon plasma (QGP) predicted qualitatively by quantum chromodynamics (QCD). We discuss whether nuclear transparency effect which is considered an important phenomenon, connected with dynamics of hadron-nuclear and nuclear-nuclear interactions could reflect some particular properties of the medium. FASTMC is used for Au-Au collision at RHIC energies. Critical change in the transparency is considered a signal on the appearance of new phases of strongly interacting matter and the QGP.
Searching for the properties of nuclear matter using proton-carbon and deuteron-carbon collisions at 4.2 a gev/c

Abstract: The present work reports the use of nuclear transparency effect of protons in proton and deuteron carbon interactions at 4.2 A GeV/c to get information about the states of nuclear matter. The half angle technique is used to extract the information on nuclear transparency. The results are compared with Dubna version of Cascade model. The average values of multiplicity, momentum and transverse momentum of protons are analyzed as a function of the number of identified protons in an event. We observed some evidence and trends in the data which could be considered as transparency effect. Analysis of the results shows that the leading effect is the basis of the observed transparency. Some contribution to the observed effect could be the existing short range correlations and the scaling power law s^-N, for exclusive two body hard scattering.
