Peng–Robinson equation of state is widely used with the classical van der Waals mixing rules to predict vapor liquid equilibria for systems containing hydrocarbons and related compounds. This model requires good values of the binary interaction parameter kij. In this work, we developed a semi-empiri[r]

In the work presented here, P216A and P233A mutant tau proteins were correctly synthesized and expressed in CHO cells, and both of these proteins were able to interact, but to differing extents, with Fyn-SH3. This suggests that the results shown here are not artefactual, owing[r]
Response evaluation of neoadjuvant chemotherapy (NACT) in patients with osteosarcoma is significant for the termination of ineffective treatment, the development of postoperative chemotherapy regimens, and the prediction of prognosis.
Further there is a critical limit of shear strength of rock joint which cannot be higher than the shear strength of weaker rock material at very high confining stress. Fig. 7.5 illustrates this idea by τ = constant saturation (critical state) line. It follows that t[r]

This paper presents an approach for reducing uncertainty related to the process of land-cover change (LCC) prediction. LCC prediction models have, almost, two sources of uncertainty which are the uncertainty related to model parameters and the uncertainty related to model structure. These uncertaint[r]
