20 Years of Independent Oil and Gas Audits: The Trinidad and Tobago Story

Over the 20 year period from 2001 to 2020, the Ministry of Energy and Energy Industries (MEEI) of Trinidad and Tobago commissioned 19 gas and 3 oil audits conducted by independent consultants. Trinidad and Tobago's natural gas Technically Recoverable Resources (TRR) moved from a P1+C1 TRR to Production Ratio of greater than 30 in 2001 to less than 10 years as production has grown from a low of 1.5 Bcf/d to a high of 4.3 Bcf/d. Despite this, the opening of a new exploration basin in the Deepwater has resulted in greater than 100% technically recoverable resource replacement in the last three years for natural gas and a 770% increase in Prospective Resources for crude oil. The data from these successful audits have served to demonstrate the astute management by the Government and People of Trinidad and Tobago of the country's hydrocarbon resources.

Development of a Low-Resource Operating Room and a Wide-Awake Orthopedic Surgery Program During the COVID-19 Pandemic

Introduction. The COVID-19 pandemic resulted in significant medication, supply and equipment, and provider shortages, limiting the resources available for provision of surgical care. In response to mandates restricting surgery to high-acuity procedures during this period, our institution developed a multidisciplinary Low-Resource Operating Room (LROR) Taskforce in April 2020. This study describes our institutional experience developing an LROR to maintain access to urgent surgical procedures during the peak of the COVID-19 pandemic. Methods. A delineation of available resources and resource replacement strategies was conducted, and a final institution-wide plan for operationalizing the LROR was formed. Specialty-specific subgroups then convened to determine best practices and opportunities for LROR utilization. Orthopedic surgery performed in the LROR using wide-awake local anesthesia no tourniquet (WALANT) is presented as a use case. Results. Overall, 19 limited resources were identified, spanning across the domains of physical space, drugs, devices and equipment, and personnel. Based on the assessment, the decision to proceed with creation of an LROR was made. Sixteen urgent orthopedic surgeries were successfully performed using WALANT without conversion to general anesthesia. Conclusion. In response to the COVID-19 pandemic, a LROR was successfully designed and operationalized. The process for development of a LROR and recommended strategies for operating in a resource-constrained environment may serve as a model for other institutions and facilitate rapid implementation of this care model should the need arise in future pandemic or disaster situations.

The Structure of the Methodology "Motivation for the Adoption of an Orphan Child by a Foster Family"

The results of validation of a new version of the methodology "Motivation for the adoption of an orphan child by a foster family" (author V.N. Oslon) are presented. The analysis allowed us to identify 9 scales (types of motivation), as well as to clarify their content. All nine scales have good internal consistency (Cronbach's alpha from 0.703 to 0.937). The convergent validity of the tool is proved. At the level of high statistical significance, the scales of the questionnaire correlate with the results obtained by standardized methods: "Family Viability Scale" M.T. Sixby (adaptation by E.S. Gusarov, M.A. Odintsova, M.G. Sorokova), "Questionnaire of emotional Intelligence" (D.V. Lyusin), "Short Questionnaire of the Dark Triad" (adaptation by M.S. Egorov, M.A. Sitnikov, O.V. Parshikov); questionnaire "Big Five" by L. Goldberg (adaptation by G.G. Knyazev, L.G. Mitrofanov, A.V. Bocharov). The methodology "Motivation for the adoption of an orphan child by a foster family" is capable of performing a prognostic function and can be used by specialists of the SPR to select resource replacement families for an adopted child, as well as to track the dynamics of changes in motivation in the process of preparing potential foster parents, actualization and mobilization of types of motivation adequate to the tasks of raising an orphan child, neutralization and correction of the inadequate ones.

FSB-DReViSeR: Flow Splitting-Based Dynamic Replacement of Virtual Service Resources for Mobile Users in Virtual Heterogeneous Networks

Virtual networks are sets of virtual devices that are interconnected through a physical network to provide services to end users. These services are usually heterogeneous (VOIP, VoD, streaming, etc.), exploit various amounts of resources (bandwidth, computing power, servers, etc.), and have topologies different from those of the substrate network. These variations in requirements are traditionally known as the architectural flexibility of virtual networks. Each virtual service is provided through a server called a virtual service resource. When a virtual service resource can no longer provide a good quality of service to end users due to the traffic variation generated by their mobility, two approaches are commonly implemented: provisioning the virtual network with resources or replacing the virtual service resource by migrating the service to another node that offers the most suitable amount of resource to satisfy the quality of service (QoS). In this paper, we propose a flow splitting-based dynamic virtual service resource replacement approach that allows for virtual service replacement across multiple virtual paths. Our approach is based on a graph topology that differs from those in the literature, which are based on tree topologies. The simulations performed in this study show that our approach significantly reduces the virtual service resource replacement time compared to other approaches.

The Geological Characteristics and Potential Evaluation of Yunnan Zhenkang Luziyuan Mining Area

Luziyuan lead zinc iron metal mining area is located in the south of Baoshan-Zhenkang lead, zinc, mercury, rare metal mineralization belt of the southwest Sanjiang metallogenic belt.According to the mine tunnel drilling and logging data, that the ore bodies are controlled by strata and faults, symbiosis and Dali rock, limestone, near ore wall rock skarnization strongly, the research shows that the deposit belongs to sedimentary transformation - skarn Pb Zn Fe polymetallic deposit. [ Mining area within the range of 1:50000, 1:50000 gravity measurements of soil geochemical survey, combined with the large scale mapping of data discovery lead zinc iron copper resources are expected to find in the eastern Luziyuan area Mangxi - Head Mountain Luojiazhai resource replacement area.
