To study the variation of ionospheric electron and ion temperatures with solar activity the data of electron and ion temperatures were recorded with the help of Retarding Potential Analyzer payload aboard Indian SROSS-C2 satellite at an average altitude of ∼500 km. The main focuses of the paper is to see the diurnal, seasonal and latitudinal variations of electron and ion temperatures during periods of minimum to maximum solar activity. The ionospheric temperatures in the topside show strong variations with altitude, latitude, season and solar activity. In present study, the temperature variations with latitude, season and solar activity have been studied at an average altitude ∼500 km. The peak at sunrise has been observed during all seasons, in both electron and ion temperatures. Further, the ionospheric temperatures vary with latitude in day time. The latitudinal variation is more pronounced for low solar activity than for high solar activity. © 2009 COSPAR.

Workload information management and resource management are two key aspects in grid computing to provide the better services to grid environment users. Grid computing also faced other challenging areas like heterogeneous nature of resources, huge number of computing elements, independency of computing resources, different processing capacities of the nodes, different types of load conditions, overloading of jobs at computing nodes, underutilized of resources, etc. A distributed load balancing algorithm is proposed that can handle any kind of grid structure. The proposed algorithm is divided into two steps: To reduce the time taken for executing the jobs or we can say reduce the response time and communication cost between transferring the jobs from one computing node to another in a grid architecture. In proposed algorithm it is shown that the load will be primarily balanced at local level to reduce the communication cost. © 2015 IEEE.

Rapid growth of internet and other technologies seems more challenging to develop the high speed networks with powerful capabilities in lower computational cost. To cover the above problem grid computing has emerged rapidly. The previous technologies such as distributed computing cluster computing, parallel computing, etc., facing the problem of space utilization. Using Grid Computing technologies the distributed resources can be accessed or used situated around the world without any geographical limitations. Algorithms developed earlier basically focused on homogenous set of computing nodes having homogenous network with higher computational speed. In this paper we are addressing the problem of adaptability, scalability and heterogeneity that creates grid computing environment more challenging. Here covered the important aspects of grid computing; scalability heterogeneity, and allocation of resources dynamically. The proposed multilevel tree architecture that is Hierarchal; Covers scalability and heterogeneity of the resources All the computing resources are independent from the architecture of grid. © 2015 IEEE.

Free-living bacteria may trigger the plant growth through production of phytohormones viz. gibberellins, auxins and cytokinins. A total 50 isolates of fluorescent Pseudomonas were screened for their ability to produce cytokinins such as isopentenyladenosine (IPA), dihydroxyzeatin riboside (DHZR) and zeatin riboside (ZR) as plant growth-promoting activity. Pseudomonas fluorescens AK1 and Pseudomonas aeruginosa AK2 were found higher phytohormones producing strains. Of the three cytokinins, IPA was the major cytokinin produced by both isolates in pure culture (5.5 and 2.9 pmol/ml, respectively) and with rice root exudates (5.9 and 3.4 pmol/ml, respectively). Production of ZR and DHZR for both organisms was found after 48 and 72 h. Amount of ZR and DHZR increased with time for both isolates in pure culture conditions. In presence of rice, production of ZR was increased 0.8 and 0.6 pmol/ml for P. fluorescence AK1 and P. aeruginosa AK2, respectively, in comparison with controls. There was no significant difference in the production of DHZR with rice exudates. © 2011 Taylor & Francis.

Route selection is a very sensitive activity for mobile ad-hoc network (MANET) and ranking of multiple routes from source node to destination node can result in effective route selection and can provide many other benefits for better performance and security of MANET. This paper proposes an evaluation model based on analytical hierarchy process (AHP), fuzzy sets and technique for order performance by similarity to ideal solution (TOPSIS) to provide a useful solution for ranking of routes. The proposed model utilizes AHP to acquire criteria weights, fuzzy sets to describe vagueness with linguistic values and triangular fuzzy numbers, and TOPSIS to obtain the final ranking of routes. Final ranking of routes facilitates selection of best and most reliable route and provide alternative options for making a robust Mobile Ad-hoc network. © 2014 IEEE.

This study deals in bio-diversity of Vesicular Arbuscular Mycorrhiza (VAM) associated with prominent medicinal plants i.e., Catharanthus roseus, Ocimum species and Asparagus racemosus in Central Himalayan region of India. Soil samples were collected from 104 locations spread at different altitudes and climatic conditions. The samples were regularly collected and observed at regular time intervals for a period of three years. In total 16 species of VAM were detected from these three medicinal plants. Approximately more than 50% of total species were identified as species of Glomus. It was observed that in Catharanthus roseus, Glomus species were dominantly present. Glomus aggregatum, Glomus fasciculatum, Glomus geosporum, Glomus mosseae, Gigaspora margarita, Gigaspora rosea, Sclerocystis sinuosa and Acaulospora laevis were found in Ocimum species. Among all the observed species of Ocimum, Glomus aggregatum and Glomus fasciculatum were predominantly present. In Asparagus racemosus, various species such as Glomus etunicatum, Glomus coranatum, Glomus mosseae, Glomus fasciculatum, Gigaspora gigantea, Gigaspora margarita, Sclerocystis sinuosa and Acaulospora scrobiculata were observed. Interestingly, species of Acaulospora and Sclerocystis were isolated from different soil types of Uttarakhand region but were never recorded as a dominant species. The study reflected a trend indicating decrease in the richness and diversity of vesicular arbuscular mycorrhizal fungi with the increasing altitude. VAM fungal spores were primarily isolated as chlamydospores and few as sporocarps. The isolated number of spores varied in count from 70 to 178 per 10 g of soil. VAM spores were found in higher abundance from sandy loam soils followed by clay and loam soils. The percentage of root colonization levels ranged 58.22-65.43, 76.88-95 and 57.21 - 63.32 for medicinal plants Catharanthus roseus, Ocimum spp. and Asparagus racemosus, respectively. © 2011 Asian Network for Scientific Information.

Mobile Agents are no longer a theoretical issue, since different architectures for their realization have already been proposed. Security is an important issue for the widespread deployment of applications based on mobile agent technology. Despite its many practical benefits, without the proper solution to the security problems, use of agent-based applications is severely impeded. This paper identifies the major issues related with the security of mobile agents and presents an architecture which is hybrid in nature i.e. uses different approaches and techniques to solve the security related problems of mobile agents. Proposed architecture is centralized at one level and distributed at other. Pull and push both approaches have been used to detect the host failure. It takes the use of existing security techniques such as digital signature, use of public and private key, intrusion detector system, signed agreement etc. to ensure the security of both mobile agents and the executing hosts.

We have investigated the Regge trajectories of exotic hadrons by considering different possible pentaquark configurations with finite quark mass in the flux tube model. Significant deviation is observed in the linear behavior of the Regge trajectories for pentaquark systems in view of the universal value of the Regge slope parameter for hadrons. The modified Regge trajectories are also compared with the available experimental and lattice data. It is observed that the nonlinear Regge trajectories of such pentaquark systems can be well described by the relativistic corrections in view of the current quark masses and the high rotational speed of the quarks at the end of flux tube structure. © 2016 World Scientific Publishing Company.

Abstract: This study analyzed the effect of various Edaphic factors on the Vesicular Arbuscular Mycorrhiza (VAM) associated with medicinal plants. Based on the richness of medicinal plants in Himalayan region, this study considered three plants i.e., Catharanthus roseus Linn., Ocimum spp. and Asparagus racemosus Willd. The study was conducted at five districts of Uttarakhand state in India viz. Pauri Garhwal, Haridwar, Dehradun, Udham Singh Nagar and Almora. This study has evaluated and analyzed the effect of edaphic factors like pH, organic carbon, potassium, phosphorous and soil type on the spore number. The correlation between the individual variations of different edaphic factors with spore number was also investigated. Change in edaphic factors greatly influence mycorrhizal diversity. Maximum number of spores were isolated from soils of pH 6.0-7.0 and with an organic carbon contents ranging from 0.82 to 0.85%. Generally, phosphorous content in the soil samples ranged from 27.11 to 37.21 k ha -1 and a feeble negative correlation was observed with respect to spore population. As the moisture content of the soil increased, it was observed that VAM fungal spore number decreased. Potassium content of soil showed significant positive correlation with spore numbers. Glomus species was observed as more versatile in comparison to others and therefore existed in even adverse soil and climatic conditions. © 2011 Asian Network for Scientific Information.

Heavy metals are toxic, persistent, carcinogenic and mutagenic in nature. Industrial wastewater is a widely known source for metal pollution in aquatic bodies as well as surface contamination. There are various techniques available for the removal of heavy metals from wastewater, like ion-exchange, membrane filtration, electrolysis, coagulation, flotation, and adsorption. However, these methods have several disadvantages like high operating cost, sludge generation and selectivity of metals. Among them, adsorption processes are extensively used for heavy metal and other pollutant removal. Biosorption is an eco-friendly, sustainable, rapid and economic process, which increases its wide application. Biosorbents are easily available and low cost in nature. Plant biomasses are commonly used as biosorbents for synthetic and real wastewater treatment. The adsorbent capacity of metal ion removal varies, depending on the nature of the adsorbent, pH, contact time, particle size, and metal concentrations. In this review paper, literature on plant based biomass has been compiled to provide concise information exploring the adsorption efficiencies in removal of toxic metals like cadmium, copper, lead, mercury, cobalt, chromium, arsenic, zinc and nickel. The metal removal efficiencies in batch and column studies are also compared. © 2016, Springer International Publishing Switzerland.
