Abstract We investigated the influence of negative emotions on arithmetic problem-solving performance and age-related differences therein. Participants were asked to verify complex multiplication problems that either true (e.g., 4 × 26 = 104) or false 5 41 201). Half five 28 140) half non-five 6 36 216). False violated five-rule, parity-rule, both rules, no rule. Problems preceded by emotionall...

A triaxial constitutive model is developed for elastoplastic behavior of geomaterials, which accounts for tensile damage. The constitutive setting is formulated in the framework of continuum thermodynamics using internal variables. The interaction of elastic damage and plastic flow is examined with the help of very simple constitutive assumptions: (i) a Drucker-Prager yield function is used to ...

Low cycle fatigue life of Ti and alloys decreases due to tensile stress dwell even at ambient temperature. This phenomenon is called Cold Dwell Fatigue (CDF). CDF properties are affected by time, test stress, microstructure. In our previous study, the effects time assessment linear cumulative damage rule were reported. The microstructure for discussed in this study. Test was from 0.85 0.955 σ0....

For many fracture problems of practical engineering importance, the three-dimensional effects are significant and a three-dimensional analysis for the problems is thus required. In this paper, an endochronic theory coupled with anisotropic damage is first established, which is actually an elasto-plastic damage theory coupled with isotropic-nonlinear kinematic hardening. The ductile damage evolu...

This study investigated the influence of nanoclay on the impact damage resistance of glass fiber-epoxy composites under high velocity ice impact loading. Addition of 0.5 wt. % nanoclay into epoxy was shown to improve damage resistance compared to composite plates having no nanoclay platelet. The glass fiber-epoxy composites containing nanoclay brought about substantial improvement in ice impact...

Background: The pathophysiology of the varicocele has received considerable study, both in humans and in animal models. The sperm DNA damage and related oxidative stress have been identified as significant cause of male infertility. Present study was designed to evaluate the testicular nitric oxide (NO) generation, lipid and carbonyl groups (CGs) peroxidation and to analyze related sperm DNA da...

This paper re-examines the implementation of short run marginal cost (SRMC) pricing principle with respect to rail infrastructure usage and empirically tests if there are maintenance costs triggered by traffic but not caused asset damage from traffic. is important because current EU legislation stipulates that only related wear tear eligible for direct cost-based element track access charges. A...

unlike the islamic code (approved 1370/1991) in which no suitable attention had been paid to the rule of interference of retaliation, the islamic punishment code (approved 1392/2013) has discussed this rule as well as the rule of interference of blood-moneys in details and in which some innovations may be seen. in spite of increase in the number of articles concerning this rule, some innovation...
