The low maintenance cost of wood plastic composite (WPC) is generating a boom in the market of wood composites products. An attempt is made to fabricate WPCs with saw dust of pine wood flour which is wastages of wood/furniture industry. These composites (WPCs) are made using matrices of recycled polypropylene (rPP) with sawdust (Pine Wood flour) as filler. Corresponding WPCs are also made using virgin plastics (vPP) for comparison with the recycled plastic based composites. All varieties of these WPCs are made through melt compounding and injection moulding with varying formulations based on the plastic type (PP), plastic form (recycled and virgin), wood four content and addition of coupling agent(MAPP). The water absorption and thickness swelling evaluated. To understand the changes in WPCs stability and durability performance, microstructure of the composites are examined, Incorporation of maleated polypropylene (MAPP) coupling agent in composite formulation improved the stability. Scanning electron microscopy (SEM) images of the fractured surfaces of WPCs confirmed that the MAPP coupling improved the interfacial bonding between the plastic and the wood filler for the series of composites.

We explore the possibility that a new-physics interaction can provide an explanation for the knee just above 106 GeV in the cosmic ray spectrum. We model the new-physics modifications to the total proton-proton cross section with an incoherent term that allows for missing energy above the scale of new physics. We add the constraint that the new physics must also be consistent with published pp cross section measurements, using cosmic ray observations, an order of magnitude and more above the knee. We find that the rise in cross section required at energies above the knee is radical. The increase in cross section suggests that it may be more appropriate to treat the scattering process in the black disc limit at such high energies. In this case there may be no clean separation between the standard model and new-physics contributions to the total cross section. We model the missing energy in this limit and find a good fit to the Tibet III cosmic ray flux data. We comment on testing the new-physics proposal for the cosmic ray knee at the Large Hadron Collider. © 2010 Springer-Verlag / Societá Italiana di Fisica. Source

Surface tension and excess volume for trimethyl benzene with tetrahydrofuran, tetra chloromethane, and diethyl solfoxide were theoretically predicted with the help of the PrigogineFloryPatterson (PFP) model over the entire concentration range at 298.15 K, which has immense sense of applicability in organic separation and synthesis as solvent. Further, we found that computed results are in good agreement with the experimental findings. The results so obtained have been explained on the basis of packing effect and dipolar-dipolar interactions. An attempt has also been made to study the excess thermodynamic functions that measure the extent of molecular interactions involved in the liquid mixture. © 2010 de Gruyter. Source

Densities and refractive indices were measured for the binary liquid mixtures formed by formamide, N-methylacetamide, di-methylformamide and di-methylacetamide with acetonitrile at T = 293.15, 298.15, 303.15, 308.15 and 313.15 K and atmospheric pressure over the whole concentration range. Lorentz-Lorentz mixing rule, Ramaswamy and Anbananthan model and model devised by Glinski were used to study the refractive index and molar refractivity. These results have been discussed to study the type of mixing behavior between the mixing molecules. The measured data were fitted to the Redlich-Kister polynomial relation to estimate the binary coefficients and standard errors. Furthermore, McAllister multibody interaction model is used to correlate the binary refractive index with the experimental findings. It is observed that molar refractivity, molecular interaction and association constant can be better understood from these models. © 2012. Source

With the advancement in mobility management in next generation, people will have an effortless, widespread, continuous access to information, activity and communication etc. when, where and how the client want it. To craft such an environment, one calls for integrating various networks that are budding from various emerging engineering practices. The Next Generation Future Network (NGFN) seems to visualize as a cluster of synchronized heterogeneous mobile interacting technologies with a unique Internet Protocol (IP). Thus to make certain about continual services during session handoffs necessitates the implementation of successful mobility and session management mechanisms in these contributing access networks. Furthermore, an efficient and effective distributive system can be valuable in wide range of areas such as: for monitoring the entry to a secure data base, refining QoS, digital media files, concurrent data structure in wireless applications and in mobile ad hoc networks. To achieve seamless mobility management for future networks (FNs), a study of WLAN and WiMAX interworking solution including integration architecture, switching procedure and inter-system measurement has been performed. For the purpose of simulation QualNet Simulator tool has been used. © 2014 IEEE. Source
