An Investigation on Fresh and Hardened Properties of Concrete Blended with Rice Husk Ash as Cementitious Ingredient and Coal Bottom Ash as Sand Replacement Material Silicon (IF 1.499) Pub Date : 2021-01-03 Naraindas Bheel, Manthar Ali keerio, Aneel Kumar, Jam Shahzaib, Zohaib Ali, Mouzzam Ali, Samiullah sohu
This research offered that the rice husk ash is served as replacement for cement ingredient such as 5%, 10% and 15% along with 10%, 20%, 30% and 40% of fine aggregates replaced with coal bottom ash in concrete. In this regard, total 180 concrete samples were prepared with mix proportion of 1:2:4 at 0.50 water/cement ratio and theses specimens were cured at 28 days. However, the main theme of this study

Influence of Nano Silica on Mechanical and Tribological Properties of Additive Manufactured PLA Bio Nanocomposite Silicon (IF 1.499) Pub Date : 2021-01-03 M. G. Ramachandran, N. Rajeswari
Fused deposition modelling (FDM) is one of the most effective 3D printing technologies and it shows high potential for various applications. The nano material reinforced FDM printed parts effectively overcome the limitations of low mechanical and tribological properties of the 3D printed parts. In this research work, the polylactic acid (PLA) / nano-silica bio nanocomposite filament was prepared for

Effectiveness of Limestone Powder in Controlling the Shrinkage Behavior of Cement Based System: a Review Silicon (IF 1.499) Pub Date : 2021-01-03 Izhar Ahmad, Dejian Shen, Kashif Ali Khan, Ahmed Jan, Mohammad Khubaib, Tahir Ahmad, Hassan Nasir
Limestone (LS) powder is commonly used in concrete from the last two decades as it is widely available and having low cost. Since, LS powder is mostly used as a replacement of cement for avoiding the CO2 emission; however its incorporation in concrete may influence the shrinkage behavior of the cementitious system mainly by filler and nucleation effect. Therefore, in this paper, the effect of LS powder

Effect of Silicon and Plant Growth Regulators on the Biology and Fitness of Fall Armyworm, Spodoptera frugiperda, a Recently Invaded Pest of Maize in India Silicon (IF 1.499) Pub Date : 2021-01-03 W. Nagaratna, C. M. Kalleshwaraswamy, B. C. Dhananjaya, Sharanabasappa, N. B. Prakash
Silicon (Si) and Plant growth regulators (PGR’s) are known to induce resistance against various insect pests. A study was conducted to determine the effect of Si and PGR’s on biology and induced resistance in maize against recently invaded fall armyworm (FAW), Spodoptera frugiperda. Different foliar silicic acid (FSA), gibberellic acid (GA3) and jasmonic acid (JA) at different concentrations and combinations

CNTFET Based 4-Trit Hybrid Ternary Adder-Subtractor for low Power & High-Speed Applications Silicon (IF 1.499) Pub Date : 2021-01-03 Suman Rani, Balwinder Singh
To go through the phenomenon at nanoscale regimes, circuits using the CNTFETbased on Ternary Logic have been explored due to their constantly increasing application in high-speed low power designs. In this paper, 4-Trit Ternary Adder-Subtractor (TAS) using Complementary metal-oxide-semiconductor (CMOS) and Carbon Nanotube Field-Effect Transistor (CNFET) is proposed, which demonstrates the ternary addition
