Abstract: :Voice over IP protocols simply enables two (or more) devices to transmit and receive real-time audio traffic that allows their respective users to communicate. In general, VoIP architectures are partitioned in two main components: signaling and media transfer. Signaling covers both abstract notions, such as endpoint naming and addressing, and concrete protocol functions such as parameter negotiation, access control and billing. Depending on the architecture, quality of service (QoS) and device optimization/management may also be part of the signaling protocol. The media transfer aspect of VoIP systems generally includes a comparatively simpler protocol for encapsulating data, with support for multiple codecs and security. Consequently, there exist a variety of different VoIP protocols and architectures. For concreteness, this paper will focus attention on a popular and widely deployed technology the Session Initiation Protocol (SIP).

Abstract: :Geometrical quantities in all orthogonal curvilinear coordinates in theoretical physics and Mathematics were built upon the Euclidean geometry, which Euclid, the Greek Philosopher and Mathematician introduced more than 2000 year ago. In this paper, we formulate some geometrical quantities in Rotational Oblate Spheroidal coordinates based on Riemann’s coordinate geometry as an extension and generalization of the Euclidean geometry.
ENGINEERED ACETOGEN BIOCATALYST REDUCES CARBON DIOXIDE AND NITROGEN DIRECTLY AND SELECTIVELY TO FUEL ISOBUTANOL IN CONTINUOUS FERMENTATION OF THE CO2 + H2 + N2 GAS BLEND

Abstract: : Industrial grade stable biocatalyst Clostridium ljungdahlii MT871RG11IBR6Nit1was engineered for the production of fuel isobutanol from the CO2 + H2 + N2 gas blend using continuous gas blend fermentation process. Viscous at temperatures below water freezing point fuel isobutanol may be blended with gasoline ($1trillion market) substituting it by up to 75% to render gasoline blend low viscosity at low temperatures. Use of air as the source of CO2 and N2 is discussed. The major sources of air CO2 now are the breathing process and the oxidation of carbohydrates for energy generation: anticipated ~ 14 billion people by the year 2050, along with the almost complete exhaustion of petroleum reserves in last 200 years while petroleum formation took over 3+million years. Using Genome Tailoring® commercial biocatalyst was engineered

Abstract: : Physico-chemical properties of sugar syrup produced from two varieties of yam using malted rice and malted sorghum were studied. Yam varieties (Dioscorea dumetorum and Dioscorea alata) were used as a major source of starch in the production of syrup. The yam varieties were dried, milled and sieved. Two sorghum varieties (White sorghum FaraFara and Red sorghum KSV8) and rice (rice faro 60 variety) were malted, dried, milled and blended into the yam flour as source of enzyme.
