the density and viscosity values at t= (293.15 to 323.15) k for binary mixtures of nitromethane with 2-propanol, 2-butanol and 2-pentanol were measured over the entire composition range. from the experimental data, excess molar volumes, thermal expansion coefficients, excess thermal expansions, partial molar volumes at infinite dilution and deviations in viscosity were calculated. the results w...

Background: The emerging world of work requires the acquisition of a set of non-technical competencies with technical competencies in a career for sustainable employment. This paper aims at designing and validating a model for integrating the ethical components with technical competencies in curriculum based on competency in industrial mechanics’ branch. Method: The research approach is based ...

Pressure overload-induced hypertrophy is a key step leading to heart failure. The Ca(2+)-induced Ca(2+) release (CICR) process that governs cardiac contractility is defective in hypertrophy/heart failure, but the molecular mechanisms remain elusive. To examine the intermolecular aspects of CICR during hypertrophy, we utilized loose-patch confocal imaging to visualize the signaling between a sin...

A study of the intermolecular potential-energy surface ~IPS! and the intermolecular states of the perprotonated and perdeuterated benzene–He complex is reported. From a fit to ab initio data computed within the coupled cluster singles and doubles including connected triples model for 280 interaction geometries, an analytic IPS including twoto four-body atom–atom terms is obtained. This IPS, and...

Springback is one of the most common and important issues in metal forming area. Due to the fact that springback depends on a variety of parameters, it is hard to predict. Hence, in this paper, the effect of continuum damage mechanics (CDM) on springback was investigated based on the Lemaitre isotropic unified damage law. Swift’s hardening law was employed to describe isotropic hardening behavi...

A vanadyl(iv) complex, K2V(O)(dtoym)2, forms polymeric interactions via intermolecular dative bonds; the intermolecular dative interaction is tuned by changes of the ligand planarity and counter cations of the vanadyl complex.

Abstract Reversible dry adhesives rely on short-ranged intermolecular bonds, hence requiring a low elastic modulus to conform the surface roughness of adhered material. Under external loads, however, soft accumulate strain energy, which release drives propagation interfacial flaws prompting detachment. The trade-off between required compliance, for conformity, and desire reduced energy rate, be...
