At temperatures moderately below their glass transition temperature, the properties of many glass-forming materials can evolve slowly with time in a process known as physical aging whereby the thermodynamic, mechanical, and dynamic properties all drift towards their equilibrium values. In this work, we study the evolution of the thermodynamic and dynamic properties during physical aging for a m...

This paper presents a new modelling approach for liquid lubricant behavior in metal forming operations by focusing on the hydrodynamic pressure build-up micro pockets. Theoretical and numerical fundamentals of proposed are introduced, upsetting an aluminum cylinder with artificial pocket is presented as validation case. The framework splits fluid-solid interaction model into computational fluid...

the source of cement in oilfields is critical to the prediction of the distribution of cements in the reservoirs and also prediction of reservoir quality. the source of mineral forming cements has been determined for the storrington oolitic carbonate reservoir (middle jurassic great oolite formation, weald basin, onshore uk) using a combination of petrography, electron microscopy, fluid inclusi...

.Hot metal gas forming of tubes can be used in various industries such as automotive and aerospace industries. In this process tube is formed at elevated temperatures, by using gas instead of fluid pressure. Lower required pressure and low power are its advantages in comparison to hydroforming process. In this paper, a hot metal gas bulging process of an aluminum alloy tube has been investigate...

We report here the draft genome sequence of Bacillus respiratorii VT-16-64, a novel spore-forming bacterium isolated from the bronchiolar alveolar lavage fluid of a patient with chronic obstructive pulmonary disease. The genome was comprised 4,831,386 bp with 4,399 predicted protein-coding genes, including those associated with antibiotic resistance and virulence.

We investigate how the non-analytic solitary wave solutions — peakons and compactons — of an integrable biHamiltonian system arising in fluid mechanics, can be recovered as limits of classical solitary wave solutions forming analytic homoclinic orbits for the reduced dynamical system. This phenomenon is examined to understand the important effect of linear dispersion terms on the analyticity of...

Open-celled, elastomeric foams allow the simple design of fully 3D pneumatic soft machines using common forming techniques. This is demonstrated through the fabrication of simple actuators and an entirely soft, functional fluid pump formed in the shape of the human heart. The device pumps at physiologically relevant frequencies and pressures and attains a flow rate higher than all previously re...
