The effect of a nickel oxide supported silica oxide (NiO/SiO2) catalyst on temperature programmed reduction (TPR) with 40% (v/v) carbon monoxide (CO) in nitrogen atmosphere as reductant agent was investigated. The conventional impregnation method was used to create the NiO/SiO2 catalysts. The reduction characteristics of NiO to Ni were investigated up to 700 °C, followed by isothermal reduction. The TPR profile of 9% NiO/SiO2 slightly shifted to lower temperature from 412 to 392 °C. Whereas the undoped NiO was reduced at a lower temperature of 387 °C. XRD diffractogram of the catalysts showed a complete reduction of NiO to Ni and have different intensities for each different loading of NiO catalyst on SiO2 support. The TEM images indicated that the carbon nanotubes were deposited on the NiO surfaces indicating some chemical reactions occur on NiO. It was found that the addition of 3% of NiO on SiO2 also exhibited a larger BET surface area (532.8 m2g−1) and insignificant pore diameter (5.9-6.0 nm). Based on these results, it is interesting to note that the addition of a small amount of NiO to SiO2 has a remarkable influence by reducing the temperature in the reduction process. The 9% NiO/SiO2 was found sufficient could enhance the reducibility of NiO at a lower temperature. [ABSTRACT FROM AUTHOR]

Abnormality location frameworks conveyed for checking in oil and gas ventures are generally WSN based frameworks or SCADA frameworks which all experience the ill effects of significant impediments. WSN based frameworks are not homogenous or contradictory frameworks. They need facilitated correspondence and straightforwardness among districts and cycles. Then again, SCADA frameworks are costly, unyielding, not versatile, and furnish information with a long postponement. In this paper, a novel IoT based engineering is proposed for Oil and gas businesses to make information assortment from associated objects as straightforward, secure, hearty, solid and speedy. This paper audits and examinations recurrence and outcomes of disappointment rates for inward and outside consumption, human activity and normal powers are dissected and the normal disappointment rate for every disappointment instrument in oil pipeline transport frameworks. Verifiable information on results of the unplanned loss of regulation of inland pipelines are evaluated. To stay away from this event, designs for the most part do pressure transient investigation in the water powered plan period of pipeline network frameworks. Demonstrating and reproduction of homeless people in pipelines is an adequate and savvy technique for evaluating this issue and discovering specialized arrangements. Qualities and restrictions of different discovery and control procedures with some down to earth models are examined. [ABSTRACT FROM AUTHOR]

Security issues of cloud computing environments are considered a major challenge for its full adoption. A Service Level Agreement (SLA) corroborates the shared management vision provided by the cloud computing paradigm, which can assist with related security issues. The necessity to address security requirements in cloud computing SLAs is considered important for both providers and consumers, along with the tools and mechanisms necessary to deal with these requirements. These issues are current research challenges; therefore, this paper aims at proposing a framework to orchestrate the management of cloud services based on security requirements defined by the SLA in an automated manner during its entire lifecycle. In addition, mechanisms to support the phases of the SLA lifecycle are proposed as a part of the framework. also the preliminary validation of the proposed framework. Finally, it is presented the integration of the framework with a cloud solution and in what manner the SLA lifecycle is supported by the framework. [ABSTRACT FROM AUTHOR]

This article presents the main features of Layer 1 L1VPN Virtual-Private Networks. It focuses particularly on aspects such as the provision and modeling of services within inter-domain environments, the supply of a Layer 1 VPN, the existent and proposed architectures, and the type of services offered through Networking Technologies together with Optical Transmission. Interaction between these aspects and new findings resulting from studies conducted by experts are analyzed. [ABSTRACT FROM PUBLISHER]
