For decades, the PWSCC on the penetration nozzles like BMI and CEDM nozzles are widely occurred all around the world. The PWSCC is dependent on the tensile stress condition, specific materials and chemical environment. Therefore, to evaluate the severity of the PWSCC, prediction of the welding residual stress on the J-groove welding part in the penetration nozzles is essential. Residual stress can be measured by using experimental methods like deep-hole drilling and X-ray diffraction, etc. However, the results of experimental methods are quite doubtable and these methods are hard to apply on the actual equipment. Therefore, computational approach like the FE analysis has been considered. The FE analysis results are very sensitive to the FE model density and analysis conditions. In this paper the optimized FE model for the residual stress analysis will be developed in the case of CEDM penetration nozzle. The optimized parameters contains bead number and mesh density. The bead numbers along the longitudinal and circumferential directions are considered and the mesh density in each the bead is also considered. The model will be verified by numerical error control.

Circular RNAs (circRNAs) constitute a recently recognized group of noncoding transcripts that function as posttranscriptional regulators of gene expression at a new level. Recent developments in experimental methods together with rapidly evolving bioinformatics approaches have accelerated the exploration of circRNAs. The differentiation of hematopoietic stem cells into a broad spectrum of specialized blood lineages is a tightly regulated process that depends on a multitude of factors, including circRNAs. However, despite the growing number of circRNAs described to date, the roles of the majority of them in hematopoiesis remain unknown. Given their stability and disease-specific expression, circRNAs have been acknowledged as novel promising biomarkers and therapeutic targets. In this paper, the biogenesis, characteristics, and roles of circRNAs are reviewed with an emphasis on their currently recognized or presumed involvement in hematopoiesis, especially in acute myeloid leukemia and myelodysplastic syndrome.

AbstractFibers obtained from different parts of the oil palm tree (Elaeis guineensis) have been under investigation for possible use in construction. Studies have been carried out investigating the engineering properties and possible applications of these fibers. However, the experimental methods employed and the values of mechanical and physical properties recorded by various authors are inconsistent. It has therefore become necessary to organize information which would be useful in the design of oil palm fiber cement composites and help researchers and engineers make informed decisions in further research and application. This review provides information about fibers from different parts of the oil palm, their properties, enhancement techniques, current and potential application in cement composites.

Recent Developments

An overview is presented of recent developments and the current status of several experimental mechanics methods, i.e., strain gages, moire´, photoelasticity, and interferometry. Examples of applications of these methods are given. Progress has been noted in all aspects, including methodology, data acquisition instrumentation, data processing, and range of applications. The trend is to tackle more difficult problems and to take full advantage of technological advances.

Laboratory experiments have always been important in psychology and are as commonly used today as ever due to the dominating position of cognitive research in international psychology. is trend has been fur- ther strengthened by recent developments in cognitive neuroscience, where experimental studies are central. Recently, experimental studies within the eld of a ective neuroscience have also received attention. Not- withstanding, experimental methods remain controversial also in psychology, and one should carefully weigh their advantages against their drawbacks. is article provides an introduction to experimental psychology, including basic principles and illustrative examples. e article focuses on the experimental method in its purest form, the controlled laboratory study, and discusses the value of this scienti c approach with regard to ecological validity and socio-cultural factors. Furthermore, the article describes the use of experiments within cognitive and a ective neuroscience as well as the inherent challenges of individual versus social perspectives when conducting micro level laboratory experiments.
