In the present paper, we have analyzed the pressure induced structural phase transitions in TiN1-xCx. Present study has been made with Three-body force potential approach, which includes coulomb and three body forces as the long range contribution whereas interactions of van der Waals and overlap repulsive type (effective up to the next nearest neighbors) considered as part of short range. In our findings, under the application of pressure, original NaCl (B1) type phase of the host binary compounds (TiC, TiN) has been transformed to its most stable CsCl (B2) type phase and similar is the case with its ternary compound (TiN1-xCx). Further, we have observed that introduction of carbon (C) at the site of Nitrogen (N) increases the transition pressure. © 2011 American Institute of Physics.

The effect of various concentrations of salicylic acid (SA) on the growth, pigment content and the activity of antioxidants was investigated in the laboratory grown wheat plants. The root and shoot growth was affected at higher concentration of SA in early days of growth. The activities of catalase (CAT), ascorbate peroxidase (APX) and guaicol-specific peroxidase (POX) declined with the application of SA (50, 500 and 1000 μM), the decrease being more pronounced with the increase in SA concentrations both in the root and leaf tissues. On the other hand superoxide dismutase (SOD) activity increased with the application of SA. At low concentrations, SA has no effect on the activities of these enzymes in vitro. Salicylic acid at higher concentrations (5- and 10 mM) though inhibited CAT activity, the activities of APX and POX remain unchanged. High concentration of SA increased the level of H 2O 2 and malondialdehyde both in root and leaf tissues. Thus, SA though has been reported to be a signal molecule for inducing various physiological and morphological attributes in plants, this study indicated the negative effect of the compound on growth and the activity of major enzymatic antioxidants.

We have incorporated the translational rotational (TR) coupling effects in the framework of three body force shell model (TSM) to develop an extended TSM (ETSM). This ETSM has been applied to reveal the second order elastic constants (C11, C12 and C44) in the dilute regimes 0≤x≤0.50. Our theoretical results have reproduced well the observed variations of C11 (x=0.14, 0.43) and C12 (x=0.14, 0.43) with temperature. The anomalous elastic behaviour observed in C44 below 150 K for x=0.43 has been predicted well by ETSM results in the orientationally disordered (NH4I)x(KI)1-x mixed crystals. Our results for C12 are in good agreement with the experimental data available for x=0.14 and 0.43. Besides, the third and fourth order elastic constants and the results on cohesive and thermophysical properties are also discussed. © 2010 Elsevier Ltd. All rights reserved.

Worldwide Interoperability for Microwave Access applications and QoS specifications are based upon class based schemes. These service classes effect to QoS for user fairness and system utilization. Improved MAX C/I algorithm considers user waiting time and channel to interference ratio but not class based scheduling schemes, after including this neglecting condition algorithm solves the problem of long distance priorities. MAX C/I and RR scheduled the instructions of execution where queue and priorities of users set. But this Improved MAX C/I condition not gain QoS specifications criteria, now mDmT resolves those neglecting conditions to resolve QoS lacking under network architecture. This comparison performs to evaluate minimum delay for user choice execution and maximum utilization of system with high efficiency. mDmT generates with the combination of MLDRR, E-APF, Modified Inverse C/I and mDmSIR which are completely designs under the instructions of WiMAX Scheduling schemes. MLDRR scheduler that not categorized sudden priorities to users because DRR show fix granularity and it gives large delay for short executable packets and low throughput. MLDRR high throughput and small delay. The property helps to overcome the problem of DRR and provides work conserving scheduler environment where scheduler never idles when packets are waiting in the queue. E- APF describes Resource management with MDRR and APF with consideration of quantum value, assign weights and priority queuing. Differentiation of quality of service (QoS) acts as modified C/I base scheduling algorithm and performs on specifications of Prioritized C/I and Modified Inverse C/I scheduling. Prioritized C/I scheduling works with MAX C/I and RR, for those users which are in equal distances from base station (BS) with different service class schemes. In Prioritized C/I, if two users having same priority then scheduler allocates execution time according to Channel Quality Indicator (CQI) values. Second is Modified Inverse C/I which is combination of MAX C/I and Inverse C/I and it improves QoS for degraded condition's user. At initial stage priorities are not decided. Least CQI value user has highest priority as compared to others, this improvement generally uses for mobile users in the degraded condition. Effective values to maintain higher throughput minimum average delay and suitable for real time services are defined by mDmSIR under light and heavy load due to avoidance of maximum latency condition for rtps flows. Advantage of these comparisons is defining how mDmT performs in various QoS criteria. For these all data Simulation acts under MAT LAB R2012a and it helps for consider mDmT scheduling algorithm gives optimal results. © 2016 IEEE.

In this research paper we are proposing a delay minimization algorithm for minimizing end to end delay for multicasting on a tree based wireless network with multiple source and multiple destinations. Our algorithm uses two stages, first is level division and second is for selecting best path among all paths from tree. The second stage is DOMA (Delay Optimal Multicast Algorithm) algorithm. Our algorithm divides the tree into its sub trees and finds the best delay optimal path. The algorithm is compared with Tree Pruning (TPA) algorithm. In tree pruning algorithm the whole tree is used for routing. Simulation result shows that our algorithm has lower end to end delay as compared with TPA. © 2016 IEEE.

The phytotoxicity and oxidative damage in response to different concentrations of Hg (0. 0, 2. 5, 5. 0, 10 and 25 μM) were evaluated in wheat plants. The root and shoot growth, content of chlorophyll and total soluble protein declined at 10 and 25 μM Hg. Roots of the plant were more affected as compared to the shoot. The malondialdehyde (MDA) quantity enhanced in the roots of wheat plants treated with 10 and 25 μM Hg and in the leaves of plants treated with 25 μM Hg. The concentration of H 2O 2 decreased at low concentration and increased at high concentration of Hg. The induction of enzymatic antioxidants (catalase, CAT; ascorbate peroxidase, APX; peroxidase, POX and superoxide dismutase, SOD) was found in the roots and leaves of plants with increased concentration of Hg up to 10 μM and low activities of these enzymes were observed at 25 μM Hg. Also, the level of K, Ca and Mg declined in leaf tissues of Hg treated plants. Thus wheat plants exposed to lower concentrations of Hg did not experience any oxidative stress. However, on treatment with 10 μM Hg, the roots and leaves responded differently. Both the leaves and roots of plants treated with higher concentration of Hg were subjected to comparatively greater oxidative damage and demonstrated that the antioxidative components were not able to remove the stress due to higher concentration of Hg and thus might affect the productivity in wheat plants. © 2011 Prof. H.S.

After the discovery of Colossal Magneto-Resistance (CMR) in the hole doped manganites, many scientists have carried out a variety of site selective substitutional studies on them to understand the underlying mechanism for this unique behaviour. In this paper, we have studied the fascinating features of Mn site substituted Pr based Doped rare earth Manganites Pr3/5Ca2/5Mn1-xZnxO3 (x=0.00 & 0.15). The variation of physical properties like grain size, average valence of Mn site were observable and AC susceptibility measurement indicates disappearance of charged ordering. It is due to variable range hopping mechanism and magnetization verses applied field loop taken at 5K for both the compound Pr3/5Ca2/5Mn1-xZnxO3 (x=0.00 & 0.15).x = 0.00 shows metamagnetic transition and x = 0.15 shows ferromagnetic nature at 5K < Tco. This shows increasing the population of hopping electrons and Mn3+/Mn4+ ratio are present in this compound.

We have investigated the elastic and thermodynamic properties for MCNi3 (M = Zr, Cd, Ag, Tc, Mg, Zn) probably for the first time, by using the modified rigid ion model (MRIM). The computed elastic constants (C11, C12, C44) are closer to the available experimental agreement. Using these elastic constants, we have computed other related elastic properties (B, G, G′, E, σ, β, B/G ratio, Cauchy pressure (C12 - C44) and Lame's parameters (μ, λ)). These properties have shown a good agreement with the available measured data. Besides, we have reported the thermodynamic properties (φ{symbol}, f, θD, υ0, γ, α). The Debye temperature obtained by us is in reasonably good agreement with the available data. The variations of specific heat with temperature are reported for a wide range and compared with the respective experimental data available in the literature. To our knowledge, some of the properties are being reported for the first report on these materials. © 2009 Elsevier B.V. All rights reserved.
