    Bulk YBCO sample is prepared using chemical route method. Ag is used as composite because of its advantageous properties. The samples are characterized by the vs T measurement performed by FOUR PROBE METHOD. Data are collected by automatic programming and analyzed for the behaviour. SEM is done to study the grain morphology. It is found that by increase in the weight percentage of Ag in the composite sample the transition temperature decreases slightly. From SEM images, it is observed that the grains become smaller in sizes as compared to prestine

    Reforming History: Turkey’s Legal Regime and Its Potential Accession to the European Union

    For the past decade, Turkey and the European Union (EU) have had serious discussions about Turkey\u27s possible entrance into the EU. The intensity of these talks, however, has always been tempered by Turkey\u27s extremely questionable human rights practices. The most marked aspects of this record are the country\u27s treatment of the Kurdish minority and its quashing of political dissent through the heavyhanded use of its legal system. In this note, I will argue that, despite Turkey\u27s increasing political and economic stature in the world, it will not be able to gain entry into the EU until it is able to sufficiently address these human rights problems to the satisfaction of the EU and the international community in general

    An Efficient Elliptic Curve Cryptography Arithmetic Using Nikhilam Multiplication

    Full text link
    Multiplication is one of the most important operation in Elliptic Curve Cryptography (ECC) arithmetic. For point addition and point doubling in ECC scalar (integer) multiplication is required. In higher order classical (standard) multiplication many intermediate operations are required. Reduced operation in multiplication will increase the functional speed of ECC arithmetic. These goals can be achieved using ancient multiplication algorithm namely Nikhilam Sutra. Nikhilam Sutra is one of the Sutra (algorithm) within 16 Vedic mathematics Sutras (algorithms). Nikhilam Sutra is efficient for multiplying two large decimal numbers. The Sutra reduces multiplication of two large numbers into two smaller numbers multiplication. The functional speed of Elliptic Curve Cryptography can be increased using Nikhilam method for scalar multiplication

    DNA Encoded Elliptic Curve Cryptography System for IoT Security

    In the field of Computer Science and Information Technology Internet of Things (IoT) is one of the emerging technologies. In IoT environment several devices are interconnected and transmit data among them. There may be some security vulnerability arise within the IoT environment. Till date, IoT has not been widely accepted due to its security flaws. Hence to keep the IoT environment most robust, we propose a stable security framework of IoT with Elliptic Curve Cryptography (ECC) using DNA Encoding. The ECC is most lightweight cryptography technique among other well known public key cryptography techniques. To increase encryption complexity, DNA encoding mechanism of DNA computing with ECC is preceded

    Secure Data Transmission over Insecure Radio Channel in Wireless of Things (WoT) Network

    Full text link
    Potential capacity of processors is enhancing rapidly which leads to the increase of computational ability of the adversary. As a result, the required key size for conventional encryption techniques is growing everyday for complex unbreakable security communication systems. The Public Key Cryptography (PKC) techniques which use larger keys cannot be fitted in tiny resource constrained Wireless of Things (WoT) devices. Some Symmetric Key Cryptosystems (SKC) use smaller keys, which can be fitted in the tiny devices. But in large networks where the number of nodes is in the order of 103, the memory constraint does not allow the system to do so. The existing secure data communication in insecure medium uses various conventional encryption methods like Public Key Cryptography (PKC) and Symmetric Key Cryptosystems (SKC). Generally, modern encryption methods need huge processing power, memory and time. Also in some cases, Key Pre-distribution System (KPS) is used among different communicating devices. With the growing need for larger key size in the conventional secure communication system, the existing resources in the communicating devices suffer from resource starvation. Hence, the need of a novel mechanism for secure communication is inevitable. But the existing secure communication mechanisms like PKC, SKC or KPS do not ensure elimination of resource starvation issue in tiny devices during communication. In these existing conventional mechanisms, the plain text is generally converted into cipher text with greater size than the plain text at the device level, which leads to resource starvation. At the time of transmission, the cipher text at the device end requires more bandwidth than the plain text which puts bandwidth overhead on the broadcast channel (BC)

    Extraction and sugar composition of mucilage in Urginea Indica​/Drimia Indica (ROXB) kunth hyacinthaceae

    Objective:Urginea indica (U. indica) Kunth. Hyacinthaceae has high mucilage content; the aim of the study is to isolate the mucilage and to analyze the sugar present in mucilage and its Physicochem. properties. Methods: The mucilage of U. indica extd. from the dried powder from bulbs of Urginea indica using Acetone Pptn. method. HPLC anal. has been made to see the presence of sugars in mucilage. The compn. of polysaccharide analyzed based on the std. hydrolysis procedure using hydrochloric, sulfuric, and trifluoroacetic acid (TFA) at elevated temp. Results: The percentage yield of mucilage was found to be 4 %. The HPLC anal. revealed the presence of sugar such as Sucrose, Maltose, Fructose and Galactose in mucilage sample among which maltose was found to be higher with 21.84 μg​/mL followed by Fructose (1.90 μg​/mL)​, Galactose (2.09 μg​/mL) and sucrose (0.82 μg​/mL)​. Conclusion: The present investigation showed that U. indica mucilage has high pharmaceutical significance with the presence of high amt. of maltose, which makes it an attractive source of carbohydrate
