  • Ponseti casting for clubfoot – fiberglass or plaster casting?

    Background: Various cast materials have been used to manage idiopathic club foot by Ponseti method of serial casting and bracing each material have it`s advantage and disadvantage. Objectives: To compare between two cast materials used to treat idiopathic clubfoot in response to the number of casts required in achieving correction, the need for tenotomy, and skin problems that can result from using these materials. Methods: Patients were randomized to fiberglass cast group and plaster cast group. The outcome measures were: the number of casts required to obtain clubfoot correction, need for Achilles tenotomy, and skin problems that are associated with the use of different cast materials Results: We enrolled 33 children in the study with 40 clubfeet. 22 (55%) clubfeet were randomized to fiberglass and 18 (45%) to plaster casts. taking in consideration that bilateral feet have the same cast material for correction. There was a significant difference in the number of casts required for clubfoot correction between the two groups (p=0.005). Tenotomy was performed in 19 (47.5%) clubfeet with no significant association between tenotomy and cast material groups. Skin problem occurred in 8 (20%) clubfeet during the process of their correction. Conclusion: The historical plaster of Paris remain to be the material of choice which can be used for correction of clubfeet by Ponseti method.

  • Study on the pollution mechanism of drinking water source water to ultrafiltration membrane

    The effects of particulate matter (represented by humic acid, kaolin and algae) on ultrafiltration membranes in micro-polluted water sources were investigated, and the mechanism of ultrafiltration membranes was further understood with the change of membrane flux and transmembrane pressure difference. The results showed that the removal rate of kaolin and algae by UF membrane was over 99%, while the removal rate of humic acid was only about 72%. Moreover, the extent of UF membrane fouling caused by humic acid was larger than that caused by kaolin and algae. The higher the concentration of humic acid, the more serious the membrane fouling was. Ultrafiltration membranes contaminated by humic acid were washed by 0.05mol/L NaOH alkali and 0.05mol/L HCL acid. The permeability of the membranes was restored to 91.24% of the cleaned surface, which was better than that of pure water, sodium hypochlorite and sodium hydroxide. It can provide better guidance for choosing appropriate cleaning agents for ultrafiltration membrane fouling.

  • Discussion on the Benefits of Port and Shipping Enterprises Based on Game Theory

    In the field of port and shipping, the mutual interest relationship between the port and the shipping company has always been a hot topic.On the one hand, the port needs the shipping company to park its port operations to obtain economic benefits and social benefits.On the other hand, shipping companies have their own considerations when facing different types of ports, and must consider them from the perspectives of maximizing their own interests and optimizing service levels.In this paper, the Stackelberg model and the Nash equilibrium model in game theory are used to analyze the basis of the choice of the interests of the port and shipping enterprises to establish a multi-influence factor and multi-targeted model of the profit distribution of the port and shipping enterprises.According to the research in this paper, the appropriate cooperation between the two parties can further enhance the efforts of the port and shipping companies, and realize the rational distribution of interests between the port and the shipping company, so as to achieve a win-win situation in the entire port supply chain.

  • Marginal and internal fit of fixed prosthodontic constructions: a literature review

    Marginal fit of fixed dental prostheses is determined by the size of the gap between the margin of the restoration and finish line of the prepared tooth. The most important factors influencing marginal and internal fit of fixed dental prostheses are the material used, the type of finish line as well as peculiarities of various technique of restoration fabrication. The objective of the article is to review the literature about the marginal and internal fit of various fixed prosthetic constructions. A review of literature using Pubmed, Google Scholar, and Research Gate database was carried out and 73 articles mostly in English were selected. The keywords were “Computer-aided design, marginal gap, internal fit, marginal fit, and crown adaptation”. Clinically accepted boundary value of marginal gap is considered to be ≤100 μm. However, a number of factors such as milling machine, parameters of bur (diameter, sharpness), software, design preparation, smooth preparation margins and incorporation of rounded line angles on the tooth preparation, the type of finish line, material and fabrication method of the construction and type of impression method should be taken into consideration in order to achieve these results. The perfect marginal and internal fit are the guarantee of construction success and longevity. As a sizeable marginal opening concedes more plaque accumulation, gingival sulcular fluid flow and bone loss, following in microleakage, recurrent caries, periodontal disease and a decrease in the longevity of the prosthetics restorations. Currently used techniques of restoration manufacturing, including constructions manufactured by computer aided design/computer aided manufacturing system can provide clinically allowable marginal fit.

  • Wind power cabin high temperature hot spot remote intelligent monitoring and early warning system

    With the increasing energy crisis, the development and utilization of wind energy, which is a substitute for traditional energy sources and has renewable and cleanliness, has gradually attracted the attention of people all over the world. While the wind power industry is growing rapidly and the unit capacity of the unit is gradually increasing, the operational safety of wind power equipment is receiving more and more attention. If the wind turbine component fails, the small one will result in downtime maintenance, and the other will cause the machine to be destroyed. Because the wind farm is built in remote areas or offshore areas far away from the city, the traffic is inconvenient, and the wind turbines are at high altitude, so it is very difficult to maintain the unit. Once a fault or fire occurs, it is difficult to rescue in time. Let it develop its accident. In view of the high cost of detection, the failure of detecting faults, and the high proportion of missed faults, the on-line monitoring of the operating status of wind power equipment, the real-time diagnosis of early warning faults, and the maintenance of equipment are also important. The online monitoring system is applied to the health monitoring of wind power equipment, which not only can alert the equipment to potential failures, avoid the occurrence of major accidents, but also can determine the fault type and severity of the equipment based on the integration of existing analytical methods. Save on operational maintenance and repair costs. At a deeper level, mining and analyzing the monitoring data can also complete the estimation of the equipment’s continuous running time before the major accident, promptly remind the staff and provide reasonable rescue plans and solutions.
