    A Mobile ad hoc network MANET is a type of network which consists of group of mobile nodes which are wireless and do not have fixed architecture The nodes act as a router and depict the nature of dynamism The three different classification of protocols in MANETS supports different applications But to support real time applications like voice signalling and video signalling we require the most efficient protocol that gives the QoS mechanism Voice and video signalling demand to know the performance of different metrics in the network such as end-to-end delay overall throughput of network and jitter of the network This paper works on identifying and analyzing the performance of various protocols like AODV DSR OLSR and TORA which would help in fulfilling the mentioned need Voice over Internet Protocol VoIP also known as IP telephony is a class of technologies used to deliver voice and multimedia sessions over internet protocol network

    cloud computing is a general term used to depict another class of system based computing that happens over the web. The essential advantage of moving to Clouds is application versatility. Cloud computing is extremely advantageous for the application which are sharing their resources on various hubs. Scheduling the errand is a significant testing in cloud condition. Typically undertakings are planned by client prerequisites. New scheduling techniques should be proposed to defeat the issues proposed by organize properties amongst client and resources. New scheduling systems may utilize a portion of the customary scheduling ideas to consolidate them with some system mindful procedures to give answers for better and more effective employment scheduling. Scheduling technique is the key innovation in cloud computing. This paper gives the study on scheduling calculations. There working regarding the resource sharing. We systemize the scheduling issue in cloud computing, and present a cloud scheduling pecking order

    Asymmetries in the Firm's use of debt to changing market values

    Using a sample of U.S. firms over the period, 1984 to 2013, this study examines the relation between market and book leverage ratios. Unlike Welch (2004) who contends that changes in market leverage do not induce adjustments in book leverage, we find an asymmetric effect. That is, firms adjust their book leverage only when the changes in market leverage are due to increases in equity values. No adjustment is observed when firm equity values decrease. Our results are consistent with Myers (1977) and Barclay et al. (2006) who argue that optimal debt levels decrease with corporate growth opportunities. © 2017 The Author

    Applications of raman spectroscopy in dentistry part II: Soft tissue analysis

    Get PDF
    Raman spectroscopy is rapidly moving from an experimental technique for the analysis of biological molecules to a tool for the real-time clinical diagnosis and in situ evaluation of the oral tissue in medical and dental research. The purpose of this study is to identify various applications of Raman spectroscopy, to evaluate the contemporary status and to explore future directions in the field of dentistry. Several in-depth applications are presented to illustrate Raman spectroscopy in early diagnosis of soft tissue abnormalities. Raman spectroscopy allows to analyze histological and biochemical composition of biological tissues. The technique not only demonstrates its role in the disclosure of dysplasia and malignancy but also in performing guided biopsies, diagnosing sialoliths, and assessment of surgical margins. Raman spectroscopy is used to identify the molecular structures and its components to give substantial information about the chemical structure properties of these molecules. In this paper, we acquaint the utilization of Raman spectroscopy in analyzing the soft tissues in relation to dentistry

    A Review of Metallothionein Isoforms and their Role in Pathophysiology

    Get PDF
    The Metallothionein (MT) is a protein which has several interesting biological effects and has been demonstrated increase focus on the role of MT in various biological systems in the past three decades. The studies on the role of MT were limited with few areas like apoptosis and antioxidants in selected organs even fifty years after its discovery. Now acknowledge the exploration of various isoforms of MT such as MT-I, MT-II, MT-III and MT-IV and other isoforms in various biological systems

    A bibliography of parasites and diseases of marine and freshwater fishes of India

    With the increasing demand for fish as human food, aquaculture both in freshwater and salt water is rapidly developing over the world. In the developing countries, fishes are being raised as food. In many countries fish farming is a very important economic activity. The most recent branch, mariculture, has shown advances in raising fishes in brackish, estuarine and bay waters, in which marine, anadromous and catadromous fishes have successfully been grown and maintained
