A granular material is most likely to possess an initial anisotropic structure due to the depositional process or the previous stress history. There is also induced fabric anisotropy during shearing. Concerning the significant influence of fabric anisotropy on the stress-strain behaviour of a granular material, in-depth investigation on the two kinds of fabric anisotropy is essential. Initial f...

In this research the stress-strain curve of porous Titanium, as a common material for biomedical application, was predicted using the mechanical properties of fully solid Titanium experimental data. Modified Gurson model (Gurson-Tvergaard-Needleman (GTN) model) was used to predict the plastic response of porous Titanium in compaction. Different values of GTN parameters were used for different i...

Abstract Diabetes mellitus is one of the major metabolic disorders. Diabetes is recognized for severe complications including diabetic nephropathy, neuropathy and retinopathy. Long-lasting effect of hyperglycemia results in increased oxidative stress. Oxidative stress results from an imbalance between radical-generating and radical scavenging systems. Increased oxidative stress has been shown ...

Rhythmic patterns related to Brazilian Portuguese adjacent stresses and secondary stress were investigated under a dynamical systems perspective. Paired utterances contrasting alleged stress clash vs non clash reveal a duration pattern difference in the opposite direction of the Rhythm Rule: the closer a syllable-sized unit is to phrase stress, the longer its duration. Polysyllabic words may ex...

Vibration of laminated composite and sandwich plate under thermal loading is studied in this paper. A refined higher order theory has been used for the purpose. In order to avoid stress oscillations observed in the implementation of a displacement based finite element, the stress field derived from temperature (initial strains) have been made consistent with total strain field. So far no study ...

background: different stressors induce learning and memory impairment and physical activity influence learning and memory enhancement. in this research, we investigated the effect of synchronized running activity with stress on acquisition and retention time of passive avoidance test. methods: male wistar rats were randomly divided into five groups as follows: control (co), sham (sh), exercise ...

The effect of the initial microstructure and intercritical annealing on mechanical properties and work-hardening response of a high-formability low carbon steel were studied. The work-hardening analysis was based on the modified Crussard–Jaoul method. The ferritic-pearlitic sheets showed low strength and high total elongation with the appearance of the yield point phenomenon. The occurrence of ...

Rhythmic properties of spoken language such as metrical stress, that is, the alternation of strong and weak syllables, are important in speech recognition of stress-timed languages such as Dutch and English. Nineteen subjects listened passively to or discriminated actively between sequences of bisyllabic Dutch words, which started with either a weak or a strong syllable. Weak-initial words, whi...
