Physical Ergonomics in Peripheral Nerve Block

The understanding of ergonomics is a vital competency for all peripheral nerve block operators. The essence of physical ergonomics for peripheral nerve block procedures can be summarised into three significant components: brain, musculoskeletal and needling. The first component includes strategies to optimise visuospatial neuroprocessing using equipment configuration. The second component reflects the careful planning of posture and position to improve procedural technique and reduce physical fatigue. The final component focuses on strategies to achieve needle beam alignment for optimal needle visualisation.

Efficient Water Softening for Avoidance of Scales in Heavy Oil Steam Floods

Pigging of Once Through Steam Generators (OTSGs) indicated various types of scales, the most predominant of these being silicates of hardness causing ions. It was noted that scaling propensity can potentially go up with higher Steam Quality (SQ) as the reject stream gets concentrated with ions. However, models suggested that there are benefits of higher SQ in enhancing fuel savings (8%) and electricity savings (2%) when SQ was increased by 20%. The challenges of higher SQ were noted in terms of increased scaling tendency and therefore the need for improved softening. In Field D, the service cycle, the backwash cycle, and the brining cycle were optimized leading to a gain in throughput and reduction in salt consumption. Service cycle improvement gained 30 % to 130 % in throughput between two regenerations, backwash cycle improvement by fluidizing the bed to nearly 35% helped gain 10% in throughput, and reduction of brining cycle from 75 minutes to 48 minutes helped reduce salt consumption by 56% without impacting the throughput. In Field B, a six month pilot revealed that shallow shell resins where ion-exchange is more efficient due to inert core (better intra particle diffusion control) can enhance the throughput by 30% - 80% and simultaneously reduce the number of regenerations by 15 – 30%. Resin fouling is still a major challenge to contend with as oil can foul the resin and throughput can decline by 0.5 – 3 folds. In a plant operation, where there are multiple softener and brine vessels, there is a need to optimize them as a system. Reliability, Availability, and Maintainability (RAM) Models are used in Field C to a) Address equipment configuration optimization with impact on capital capacity expansion project scope b) Understand how net softwater delivery capacity was affected by increases in inlet hardness and c) Assess through a comparison scenario, if the large cost of addressing the valve issue in an upstream nutshell filter was worth the lost production opportunity related to unplanned downtime.

Unmanned Aerial Vehicle for Transmission Line Inspection: Status, Standardization, and Perspectives

As the biggest country in power consumption and generation, China owns the largest scale of transmission line worldwide. The application of unmanned aerial vehicle (UAV) in inspection has been carried out for many years in China because of its strong adaptability and safety compared to the traditional manual way. For the further development of UAV application technology in transmission line inspection, China has accumulated rich experiences and greatly improved line inspection efficiency and formed a relatively complete UAV transmission line inspection standardization system including operation safety management, an equipment configuration method, and functional quality requirements. However, there still exist some obstacles that need to be tackled due to the fact that China’s UAV transmission line inspection standardization and its international promotion have not been thoroughly and comprehensively studied at present. Based on an in-depth analysis of China’s current UAV transmission line inspection standardization system, this study employs SWOT-PEST analysis to insightfully investigate international promotion opportunities/challenges under the current situation, upon which several constructive suggestions are proposed from four aspects of politics, economy, society, and technology. The ultimate purpose is to design feasible schemes to boost the international promotion of China’s UAV transmission line inspection standardization and further development of international UAV inspection technology.

PUMPING STATION AND STAMPING MACHINE FOR THE PRODUCTION OF RADIATION SOURCES

The article describes a five-lamp pumping station and a semi-automatic stamping machine for the production of bactericidal ultraviolet lamps. Standard methods of production and testing of pumping stations and stamping machines were analyzed. In the course of work and on the basis of the conducted research, the technical characteristics and equipment configuration were worked out. The pumping station is designed for processing simultaneously five products that will later be bactericidal ultraviolet lamps, including: decontamination of products, oxidation of electrodes, filling products with a gas mixture to the working pressure, loading amalgam and desoldering. This equipment ensures the fulfillment of the production volume for the production of bactericidal lamps. When designing and manufacturing electrical equipment, components from the world's leading manufacturers are used. The use of high-quality materials can significantly increase the efficiency of equipment operation. The latest technical solutions combined with a well-thought-out design make it possible to successfully integrate this equipment into integrated automated control systems.
