Role of Electron Donors in MgCl2 Supported Ziegler-Natta Catalysis: DFT Approach
Abstract: An insight into the nature of carbonate-based electron donors in high-activity MgCl2 supported Ziegler-Natta (Z-N) catalysts has been studied and compared with conventional phthalate and diether systems by employing density functional theory (DFT) calculations. In the catalyst activation (one of the important processes to produce the active catalyst sites), the conventional monometallic and recently characterized bimetallic (TiCl2(Et)–Cl–AlEt2) active site are studied in the presence/absence of electron donors. These active sites …

Structure-Property Correlation in PTT/PP Blends with Improved Mechanical Performance
Abstract: The present work investigates a series of poly (trimethylene terephthalate) (PTT)/polypropylene (PP) blends prepared with varying PP concentrations in order to improve the overall performance of PTT, particularly with respect to mechanical properties and processability. PTT is a promising engineering thermoplastic owing to its balanced stiffness, resilience, and chemical resistance; however, its relatively high cost and processing limitations often restrict its wider application. In this context, blending with PP offers …

Lumped Construction Sequence for Column Shortening Analysis in High Rise Building with Outrigger System
Abstract: The exact value of column shortening is not a straightforward task. Various parameters are affected on column shortening results like rate of construction sequence and reinforcement ratio. The building should stand with high stiffness and must be able to resist lateral deformation without having discomfort to the user. The excessive drift is controlled by using outrigger system. In high rise buildings, the construction sequence analysis and conventional sequence analysis are …

Loan Prediction Using Random Forest Algorithm
Abstract: With the growth of the banking sector, more and more people are applying for bank loans. All of these loans are not allowed. The principal income of bank assets arises from the interest earned on the loan. Bank profit or loss depends largely on the amount of the loan, i.e., whether customers pay off the loan or fail. The main purpose of banks is to invest their assets in secure …

Study on the Response of Strengthening Strategies for Masonry-infilled Open Ground Storey Framed Building
Abstract: The strengthening of reinforced concrete (RC) frame buildings with masonry infill wall and with open ground storey is a very timely and significant topic because of the poor performance against seismic action. The absence of infill walls in the ground storey makes the ground storey less stiff and weaker than the all upper storys which results in a poor performance against lateral loads. Soft storey mechanism prevails in these cases …
