Multicasting allows IP traffic to be sent from many sources and transmitted to multiple destinations. In multicasting, a single data packet is directed to a multicast group identified by a single IP destination group address instead of sending individual packets to each destination. For the multicast sessions to be efficient, the network must transmit data in these sessions using minimal network resources. Multicasting optimizes the performance of the network, as only one multicast data stream is transmitted preserving bandwidth and eliminating traffic redundancy. Multicasting also provides enhanced efficiency by controlling the traffic on the network and reducing load on network devices.

The ability of activated carbon prepared from Papaya stem to adsorb Pb(II), Cu(II), Cr(III), Fe(II) and Zn(II) ions from synthetic wastewater has been studied through batch experiment. Batch adsorption study was performed to observe the effect of contact time, pH and initial metal ion concentration on adsorption of Pb(II),Cu(II), Cr(III) , Fe(II) and Zn(II) ions from synthetic wastewater. The results obtained from the studies reveal that, the adsorption of metal ions depends upon initial metal ion concentration, pH and contact time. The optimum contact time, initial metal ion concentration and pH for Pb(II) is 5 hrs., 9 mg at pH 8, for Cu(II) 5 hrs, 8 mg at pH 8, for Cr(III) 5 hrs.9 mg at pH 8, for Fe(II) 5 hrs. 9 mg at pH 10 and for Zn (II) 5 hrs, 9 mg at pH 8 respectively. Langmuir and Freundlich isotherms were studied and the values obtained are in agreement with Langmuir isotherm and better fitted to Freundlich isotherm. The aim of this work is to develop inexpensive, easily available, effective adsorbents from papaya stem as alternative to existing commercial adsorbents.

The viscosity of a fluid is a measure of it‟s resistance to gradual deformation by shear stress or tensile stress. For liquids, it corresponds to the informal concept of "thickness"; for example, honey has a much higher viscosity than water. A lubricant is a substance introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces.The property of reducing friction is known as lubricity which is known to be good for other people's daily uses.Viscosity is an internal property of a fluid that offers resistance to flow.

During the last few years we have all witnessed steadily increasing growth in the deployment of Mobile Ad hoc network (MANET). They consist of nodes that are able to communicate through the use of wireless mediums and form dynamic topologies. Unfortunately, mostly broadly used routing protocols in MANET have no security considerations and trust to the participant nodes in order to correctly forward routing and data traffic. In order to maintain connectivity in such network all participating nodes have to perform routing of network traffic. The cooperation of nodes cannot be enforced by a centralize administration authority since one does not exist. Therefore, network layer protocols are key force to enforce connectivity and security requirements in order to guarantee the undisrupted operation of the higher layer protocols.

Over the years, Mobile Ad Hoc Networks (MANETs) are foremost necessary form of circumstantial wireless network, where mobile nodes join together on an extemporaneous basis. MANETs are both self-healing and self-forming, and let the communications begin between mobile nodes peer to peer level with no support of fixed infrastructure or federal administration. These attributes of MANETs bring vital advantages in a circumstances that features vastly mobile users or platforms, ought to share IP-based information, or a situation where fixed network infrastructure is supposed to be impractical, impaired, or extremely complex to laid down, which gives rise to more concern about performance of MANET. In this paper we developed a stochastic technique also known as queueing approach for MANET which evaluates some of the performance metrics.

Taiwan coast is surrounded by the Taiwan Strait and the Pacific Ocean. Sandy coasts are majority and severely scoured by North-Easterly winter monsoon and summer and autumn hurricane (i.e. typhoon).Link block (shore protection concrete block) are largely placed along the beach or vertical to the beach or even arranged offshore parallel to coast (i.e. offshore breakwater) to induce sediment behind the offshore breakwater to reclaimed the lost sand of beach (i.e. beach nourishment). Link block protect seaport such as Taipei Commercial Port Mailiao Industrial Port and fishery ports etc. Link block has a great function for shore protection and a good wave absorber for breakwater construction. It contributes a great potential ability to prevent wave action on the coastal zone...............

Steganography is the study and analysis of the art and science of concealing or protecting sensitive communication. The concealed entity might be anything from a file, message, video, image or even audio and it is embedded into other videos ,images or files, etc. In this paper we will be presenting various types of Steganography as well as the factors driving the success of a good stego system.

This research analyzes the potential of agribusiness and the availability of facilities and infrastructure, formulating a strategy of developing agribusiness product transaction centers. The method used is field survey and comparative study at Sub Terminal Agribusiness of Sewukan and Central Market of Puspa Agro East Java and SWOT analysis. The results showed that the potential of vegetable agribusiness in Sub Terminal Agribusiness of Sumillan is very high, management of information management is still limited. Building lods of vegetables, warehouses and packing house building, vegetable waste processing technology have not been equipped facilities.

Schiff base nano complexes of Zirconium(IV) and Thorium(IV) of general composition ML2 have been synthesized using DFMPM and Histidine. The complexes were prepared by standared methods.The melting point, elemental analysis, molar conductance, magnetic moment studies were conducted and the complexes were characterized by IR, UV–Vis, 1H NMR, SEM, and XRD. Based on the above studies the ligand was bidentate and the complexes were hexa coordinated proposing octahedral geometry to the complexes and are nano crystalline in size. Biological studies such as antibacterial, antifungal and DNA cleavage studies of the complexes indicated that the complex have better antibacterial, antifungal and DNA cleavage properties. The XRD and SEM studies revealed the nano crystalline nature of the complexes. The conductance measurements indicated the non-electrolytic nature of the complexes and are used for the removal of these metals from water .
