The relation between the stored energy and the Taylor factor (TF) has been investigated using the SEM/EBSP analysis in an Al-Mg-Mn alloy sheet worked by the continuous cyclic bending (CCB). The analysis reveals that the stored energy is high for the high TF region, whereas a significant increase of the stored energy with the decrease of the Taylor factor appears in the vicinity of the minimum T...

nanofibrillated cellulose fibers were produced from unbleached kraft pulp of kenaf bast fiber. air dried and vacuum filtrated films of cellulose nanofibers were produced and their density and tensile properties were investigated. kenaf bast fiber unbleached kraft pulp has good potential for production of cellulose nanofibers by microfluidizer; so that the use of kenaf bast fiber unbleached kraf...

Background: The consumption of low quality foods is common in low socioeconomic areas; and according to epidemiological studies, the density of nutrients often proves the quality of diet. This study aimed to compare the density of macronutrients and micronutrients in various parts of Tehran.   Methods: This was a cross-sectional study performed from September to December 2007 in all the...

Few multiaxial constitutive laws under the vasoactive condition have been proposed as compared with those under the passive condition. The author and his colleagues have studied biaxial isometric properties of vasoactive rabbit arteries [1] although the constitutive law has not been proposed. The experiments for 10 common carotid arteries of rabbit were performed under the passive condition and...

A method of damage identification of piles was established by using vibration characteristics. The approach focused on the application of the element strain energy and sensitive modals. A damage identification equation of piles was deduced using the structural vibration equation. The equation contained three major factors: change rate of element modal strain energy, damage factor of pile, and s...

background: little is known about the effects of a low energy dense diet on weight maintenance and cardiovascular risks following a recent weight reduction. therefore, we assessed if weight maintenance, lipid profiles, and glycemic control differ between low energy density (led) diet and usual diet consumers following a recent weight reduction. materials and methods: in this randomized controll...

bacteria use a chemical language to communicate with each other which enables them to synchronize gene expression as a result of cell density. this special language which is called quorum sensing (qs) is based on producing and sensing the small signals and eventually leads them to perceive when a minimum population unit is reached. on the contrary, quorum sensing blockade (quorum quenching) has...

The traditional Hessian-related vessel filters often suffer from the problem of handling non-cylindrical objects. To remedy the shortcoming, we present a shape-tuned strain energy density function to measure vessel likelihood in 3D images. Based on the tensor invariants and stress-strain principle in mechanics, a new shape discriminating and vessel strength measure function is formulated. The s...
