this paper presents a new model for predicting the compressive strength of steel-confined concrete on circular concrete filled steel tube (ccfst) stub columns under axial loading condition based on artificial neural networks (anns) by using a large wide of experimental investigations. the input parameters were selected based on past studies such as outer diameter of column, compressive strength...

In this paper, nanoscale wetting on groove-patterned surfaces is thoroughly studied using molecular dynamics simulations. The results are compared with Wenzel's and Cassie's predictions to determine whether these continuum theories are still valid at the nanoscale for both hydrophobic and hydrophilic types of surfaces when the droplet size is comparable to the groove size. A system with a liqui...

Virulence of the opportunistic yeast, Candida albieans, involves the interplay of many complex changes including the yeast-hyphae transition, which mainly involves protein changes. Cell wall mannoproteins are found to be the main cause of adherence of C. albieans to epithel ial cells in the first step of an infection process. In the present study, cell wall mannoproteins of intact yeast wer...

• A feasible path-based procedure allows to bypass the simulation failures due non-ideal thermodynamics or complex optimization algorithms. The proposed use a shortcut design provided by ProSimPlus® process simulator initialize algorithm coupled with rigorous simulations. Although “non-optimal”, DWC obtained via fulfills expectations both from an economic and environmental point of view respect...

The distillation process remains as the most common method ofseparation in chemical process industries. The energy used from this process accounts for an estimated 3% of <span style="font-size: 10pt; c...

/Description The PS-rich and neutral PS-b-PMMA block copolymer (BCP) films were spin coated on the neutral random copolymer hydroxyl-terminated PS-r-PMMA layers grafted on the native oxide and 50 nm thick PECVD amorphous silicon oxide layers. Relationship between the grafting density of BCP and surface density of hydroxyl moiety on silicon oxide is discussed. Furthermore, optimization of anneal...
