Abstract Plant derived natural fibers have been widely investigated as alternatives to synthetic fibers in reinforcing polymers. Researchers over the years have explored many plant fibers using different extraction processes to study their physical, chemical, and mechanical properties. In this context, the present study relates to the extraction, characterization, and optimization of Typha angustata L. stem fibers. For this purpose, desirability functions and response surface methodology were applied to simultaneously optimize the diameter (D), linear density (LD); yield (Y), lignin fraction (L), and tenacity (T) of Typha stem fibers. Typha stems have been subjected to both alkali (NaOH) and enzymatic… More > Graphic Abstract

Abstract Tailings known as solid waste are generated by the mining industry. The development of tailings as wet shotcrete aggregates has significant economic and environmental benefits. The fine particle size of the tailings results in a large consumption of traditional cement as a cementitious material and insignificant improvement in strength. Therefore, a composite cementitious system of cement and solid waste resources (fly ash and slag powder) is explored for this study. In this paper, the response surface methodology (RSM) is used to optimize the experimental design and a multivariate nonlinear response model with cement, fly ash… More >

Abstract Craniosynostosis is a common congenital craniofacial deformity caused by premature ossification and closure of one or more cranial sutures. Craniosynostosis will not only affect the normal development of the skull, but also may cause a variety of complications, damage the nervous system, and cause long-term effects on the development of physical and mental health. Therefore, it is particularly important to provide new ideas for clinical treatment by studying the rehabilitation methods of craniosynostosis, and to improve the cure rate. To this end, this paper studies the early rehabilitation methods after craniosynostosis surgery and designs a… More >
