 Civil Engineering Research Journal- Juniper Publishers Abstract Prestressed concrete containment vessel (PCCV) is the unique structures that are constantly exposed to harsh environmental conditions, acts as the final defensive shield against radiation leakage, and ensuring the structural safety of the dome is critical in nuclear power industry. Many related studied about the internal pressure capacity of PCCV are summarized in this paper. Keywords:  Ultimate internal pressure; Prestressed concrete containment vessel; Mechanical analysis, Failure mode; Finite element Go to Introduction The nuclear containment acts as the final barrier against the release of radioactivity. Hence, its design, strict performance and safety evaluation under severe conditions are of great significance, whether through experiments or by numerical methods. In particular, the behavior prediction from functional to structural failure when the internal pressure is higher than the design pressure (Pd) is...

 Civil Engineering Research Journal- Juniper Publishers Opinion In the modern view generally accepted by non-scientists, science is understood to be the process, or method of accumulating abstract truths. From this perspective, truths are composed of multiple facts that may be universally applied. For example, the properties of lead are said to be the same in Zimbabwe as they are in Canada. Once scientists establish such truths, they are handed-over to practical designers (e.g., engineers, architects, medical practitioners ….) to solve problems in the messy conditions of the world. Surprisingly, however, this modern dualistic view of the world is less a departure from the mystical past than was claimed by advocates of modernity. Rather, modern philosophical dualisms simply reproduce the ancient separation of mind and matter, or God and man. Such popular understanding of science suggests that we have not yet finished the Modern project. One problem with these popular modern dualisms...

 Civil Engineering Research Journal- Juniper Publishers Abstract Although there are studies that compared between indirect left-turn treatments such Median U-turn (MUT) or RCUT to the Conventional Intersection (CI) designs, very few have compared between the operational performances of MUT versus RCUT. Furthermore, few studies on the Quadrant Roadway Intersection (QRI) were found in the literature. The main objective of this paper is to assess different designs for the accommodation of left turns through indirect maneuvers. Traffic performance of the proposed intersection designs was evaluated based on microsimulation. The results revealed that the difference between the two designs, RCUT and MUT lies in the amount of traffic rerouted to the crossover intersections. Increasing the traffic downstream of the main intersection to the crossover intersection still has an effect on the main intersection’s operations. Proper design and spacing is needed at the crossover intersection to mi...
