Aiming at the construction of infill wall structural column are often used in artificial layer pouring method and top pouring back method, to improve the structure of wall column concrete pouring process, puts forward a new type of structural column concrete pouring machine. The application of this equipment, process worker can finish pouring filled wall structure column and tap filled wall str...

1,3-butadiene is an essential platform chemical for producing rubberlike polymers, which extracted from C4 hydrocarbons that are produced through steam cracking. The current state-of-the-art technology the BASF process uses thermally coupled extractive distillation (ED) followed by two columns. However, requires high temperature heat input, thus cost hot utility and reduces possibility integrat...

Abstract Divided‐wall column (DWC) is an intensified separation process and so far developing a simple procedure for designing these units has been challenging. In this work, the concept of molecular tracking integrated with conventional methods to build easy‐to‐use methodology DWCs multicomponent separations. Application proposed approach highlighted through several three‐ four‐component mixtu...

BACKGROUND The aim of this study was to explore the surgical treatment of transverse with or without posterior wall fractures of the acetabulum. MATERIAL AND METHODS We surgically treated 21 consecutive cases of pure transverse (7 cases) and with posterior wall (14 cases) fractures of the acetabulum. The anterior column fractures were firstly reduced, temporarily fixed through a modified Smith-...
