A Simple Sol Gel Protocol Towards Synthesis of Semiconducting Oxide Nanomaterial
G.S. Devi,H.Z.R. Hamoon,A. Nanaji,K.R. Reddy
Journal of Nano- and Electronic Physics , 2011,
Abstract: Nanostructured Tin oxide (SnO2), powders was synthesized by employing a novel Sol-gel protocol at RT. A wide variety of techniques such as energy – dispersive spectroscopy(EDX), N2 sorption, X-ray diffraction (XRD), have been used to study the formation process and characterization of the nanoparticles obtained. Transmission electron microscopy (TEM) has been applied to find out about the shape and size distribution of the particles. The nanoparticles thus synthesized were monodispersed, with an average particle size of ~ 10 nm and spherical in shape. The EDX analysis revealed the presence of Sn, O signal in the synthesized nanoparticles confirming the purity of the synthesized samples. This protocol appears promising for application in large-scale synthesis of nanoparticles.
Efficient Implementation of Conditional Shortest Path Routing in Delay Tolerant Networks
International Journal of Computer Science and Communication Networks , 2011,
Abstract: Routing in delay tolerant networks (DTN) is a challenging problem because at any given time instance, the probability that there is an end-to-end path from a source to a destination is low. Since the routing algorithms for conventional networks assume that the links between nodes are stable most of the time and do not fail frequently, they do not generally work in DTN’s. Therefore, the routing problem is still an active research area in DTN’s To realize the DTN vision, routes must be found over multiple unreliable, intermittently-connected hops. Many researchers have investigated this fundamental challenge, to overcome these challenges, this paper propose Conditional Shortest Path Routing (CSPR) protocol that routes the messages over conditional shortest paths in which the cost of links between nodes is defined by conditional intermeeting times rather than the conventional intermeeting times. Through trace-driven simulations, we demonstrate that CSPR achieves higher delivery rate and lower end-to-end delay compared to the shortest path based routing protocols that use the conventional intermeeting time as the link metric
Implementation of Personalized E-Mail Prioritization-A Content Based Social Network Analysis
International Journal of Computer Science and Communication Networks , 2011,
Abstract: Now a Day’s, Email is one of the most prevalent personal and business communication tool, but it exhibits some significant drawbacks. One of the drawback of this is the portion of e-mail is that spam, has increased dramatically in the past few years. A recent study showed that 52 percent of e-mail users say spam has made them less trusting of e-mail, and 25 percent say that the volume of spam has reduced their e-mail use. This crisis has prompted proposals for a broad spectrum of potential solutions, ranging from more efficient antispam software tools to antispam laws at both the federal and state levels. But Still there is a necessity, to overcome this, in this paper We propose a novel approach that combines unsupervised clustering, social network analysis, semi supervised feature induction, and supervised classification to model user priorities among incoming email messages. This article presents the first study on PEP with a fully personalized methodology, where only each user’s personal email data. Finally results show that this method somehow better compared to other methods

Damodar Nanaji Balpande,Chandra Shekhar Pathak,Amit Agrawal,Brij Raj Singh
Iranian Journal of Pediatrics , 2009,
Abstract: Background:Hemihydranencephaly is a rare disorder of the brain characterized by complete or almost complete unilateral absence of cerebral cortex with preservation of meninges, basal ganglia, pons, medulla, cerebellum, and falx. Case Presentation:Thirteen year-old male child presented with left sided upper and lower limb weakness with facial asymmetry since the age of six months. His magnetic resonance imaging (MRI) scans demonstrated a nearly complete absence of the right cerebral hemisphere including basal ganglion, which was replaced by cerebrospinal fluid with a small residual rim of the occipital cortex. The imaging features were suggestive of right-sided hemihydranencephaly. Conclusion:Patients with hemihydranencephaly provide an experiment of nature with potential implications for normal cognitive development and illustrate how much there is still to be learned about human development.

International Research Journal of Pharmacy , 2011,
Abstract: In the present investigation was to evaluate the antioxidant capacity of various extracts from whole plants of Dolichos biflorus with the help of three in-vitro antioxidant models were carried out for total antioxidant activity (phosphomolybdic acid method), ferric-reducing antioxidant potential (FRAP) assay and iron chelating method. Methanolic extract of Dolichos biflorus was showed more effective in free radical scavenging activity in total antioxidant activity, FRAP and iron chelating methods than that of other two extracts. The results obtained in the present study indicate that the methanolic extract of whole plants of Dolichos biflorus are a potential source of natural antioxidant.
The Spread of Infectious Disease on Network Using Neutrosophic Algebraic Structure  [PDF]
A. Zubairu, A. A. Ibrahim
Open Journal of Discrete Mathematics (OJDM) , 2017, DOI: 10.4236/ojdm.2017.72009
Abstract: Network theory and its associated techniques has tremendous impact in various discipline and research, from computer, engineering, architecture, humanities, social science to system biology. However in recent years epidemiology can be said to utilizes these potentials of network theory more than any other discipline. Graph which has been considered as the processor in network theory has a close relationship with epidemiology that dated as far back as early 1900 [1]. This is because the earliest models of infectious disease transfer were in a form of compartment which defines a graph even though adequate knowledge of mathematical computation and mechanistic behavior is scarce. This paper introduces a new type of disease propagation on network utilizing the potentials of neutrosophic algebraic group structures and graph theory.

Abstract: The compound lead oxide sulfate PbSO4.PbO was prepared in our laboratory. The Thermal behavior of PbSO4 was studied using techniques of Thermogravimetry under air atmosphere from 25 to 1200°C. The identity of both compounds was confirmed by XRD technique. Results obtained using both techniques support same decomposition stages for this compound. The electron microscopic investigations are made by SEM and TEM. The compound is characterized by XRD and the purity was determined by analytical Methods. Also a series of thermogravimetric analysis is made and the ideal condition is determined to convert this compound to pure lead oxide.
Metal ion-binding properties of L-glutamic acid and L-aspartic acid, a comparative investigation  [PDF]
S. A. A. Sajadi
Natural Science (NS) , 2010, DOI: 10.4236/ns.2010.22013
Abstract: A comparative research has been developed for acidity and stability constants of M(Glu)1, M(Asp)2 and M(Ttr)3 complexes, which have been determined by potentiometric pH titration. Depending on metal ion-binding properties, vital differences in building complex were observed. The present study indicates that in M(Ttr) com-plexes, metal ions are arranged to the carboxyl groups, but in M(Glu) and M(Asp), some metal ions are able to build chelate over amine groups. The results mentioned-above demonstrate that for some M(Glu) and M(Asp) complexes, the stability constants are also largely determined by the affinity of metal ions for amine group. This leads to a kind of selectivity of metal ions, and transfers them through building complexes accompanied with glutamate and aspartate. For heavy metal ions, this building complex helps the absorption and filtration of the blood plasma, and consequently, the excursion of heavy metal ions takes place. This is an important method in micro-dialysis. In this study the different as-pects of stabilization of metal ion complexes regarding to Irving-Williams sequence have been investigated.

A. Alanezi, A. Qadrouh
Open Journal of Geology (OJG) , 2013, DOI: 10.4236/ojg.2013.32B004

This study was carried out in Harat Rahat (south of Almadinah Almonwarah) using seismic reflection and resistivity methods. The main objectives of this study are to determine the extent of the basaltic layer and to define the subsurface faults and fractures that could affect and control the groundwater movement in the study area. A 2D seismic profile was acquired and the result shows that the subsurface in the study area has a major fault. We obtained a well match when the seismic result was compared with drilled wells. As a complementary tool, the resistivity method was applied in order to detect the groundwater level. The results of the resistivity method showed that six distinct layers have been identified. The interpretation of these six layers show that the first three layers, the fourth layer, the fifth layer and the bottom of the section indicated various subsurface structures and lithologies; various basaltic layers, fractured basalt, weathered basement and fresh basaltic layers, respectively. It is obvious that the eventual success of geophysical surveys depend on the combination with other subsurface data sources in order to produce accurate maps.
